Emerging diagnostic technology that uses artificial intelligence (AI) has demonstrated the potential to free dermatologists from the burden of triaging skin lesions, but dermatology lags behind some other specialties in harnessing the power of AI, and confusion surrounds dermatologists’ role in using this technology, according to researchers and dermatologists investigating AI.

While some AI-integrated devices designed to triage skin lesions have emerged, including one that received Food and Drug Administration (FDA) clearance earlier in 2024, it may be some time before AI has a meaningful clinical impact in dermatology and, more specifically, the diagnosis of skin cancer, Ivy Lee, MD, a dermatologist in Pasadena, California, and chair of the American Academy of Dermatology’s augmented intelligence committee, told this news organization.

“It hasn’t really translated into clinical practice yet,” Dr. Lee said of AI in dermatology. “There have been significant advances in terms of the technical possibility and feasibility of these tools, but the translation and integration of AI into actual clinical work flows to benefit patients beyond academic research studies has been limited.” More studies and more “easily accessible and digestible information” are needed to evaluate AI tools in dermatologic practice.

“In dermatology, we’re on a cusp with AI,” said Rebecca Hartman, MD, MPH, chief of dermatology at the VA Boston Healthcare System and director of melanoma epidemiology at Brigham and Women’s Hospital, Boston, Massachusetts. “I think it’s going to come and change what we do,” which is especially true for any image-based specialty,” including radiology and pathology, in addition to dermatology.

Dr. Hartman led a study of one of these emerging technologies, the handheld elastic scattering spectroscopy device DermaSensor, which was cleared by the FDA in January for evaluating skin lesions suggestive of skin cancer.
 

Early AI Devices for Skin Cancer Detection

At the American Society for Laser Medicine and Surgery (ASLMS) meeting in April, a panel explored a number of algorithms with dermatologic applications that use AI to triage skin lesions, including DermaSensor.

Raman spectroscopy, which contains a handheld Raman probe, a diode laser, and a detecting spectrograph. A laser beam — which at 1.56 W/cm² is below the maximum permissible exposure — focuses on the skin target with a 3.5-mm spot, gathers data on the target, and feeds it back into the unit that houses the algorithm that evaluates the spot analysis. It’s still in the investigative phase. A clinical trial, published almost 5 years ago, demonstrated a sensitivity of 90%-99% and a specificity of 24%-66% for skin cancer.

A dermatoscope called Sklip clips onto a smartphone and performs what company cofounder Alexander Witkowski, MD, PhD, described as an “optical painless virtual biopsy” for at-home use. The device uploads the captured image to an AI platform for analysis. It received FDA breakthrough device designation in 2022. At the ASLMS meeting, Dr. Witkowski said that clinical performance showed the device had a 97% sensitivity and 30% specificity for skin cancer.

DermaSensor, described in the study conducted by Dr. Hartman and others as a noninvasive, point-and-click spectrometer, is a wireless handheld piece that weighs about 10 ounces. The unit captures five recordings to generate a spectral reading, which an algorithm in the software unit analyzes. The study found a sensitivity of 95.5% and specificity of 32.5% for melanoma detection with the device.

The target market for DermaSensor is primary care physicians, and, according to the FDA announcement in January, it is indicated for evaluating skin lesions “suggestive” of melanoma, basal cell carcinoma (BCC), and/or squamous cell carcinoma (SCC) in patients aged 40 and older to “assist healthcare providers in determining whether to refer a patient to a dermatologist.”
 

So Many Cases, So Few Dermatologists

In dermatology, AI devices have the potential to streamline the crushing burden of diagnosing skin cancer, said Yun Liu, PhD, a senior staff scientist at Google Research, Mountain View, California, who’s worked on developing machine-learning tools in dermatology among other medical fields. “Many people cannot access dermatology expertise when they most need it, ie, without waiting a long time. This causes substantial morbidity for patients,” Dr. Liu said in an interview.

His own research of an AI-based tool to help primary care physicians and nurse practitioners in teledermatology practices diagnose skin conditions documented the shortage of dermatologists to triage lesions, including a finding that only about one quarter of skin conditions are seen by a specialist and that nonspecialists play a pivotal role in the management of skin lesions.

The Centers for Disease Control and Prevention reports that about 6.1 million adults are treated for BCC and SCCs each year. The American Medical Association estimates that 13,200 active dermatologists practice in the United States.
 

Overcoming Barriers to AI in Dermatology

Before AI makes significant inroads in dermatology, clinicians need to see more verifiable data, said Roxana Daneshjou, MD, PhD, assistant professor of biomedical data science and dermatology at Stanford University, Stanford, California. “One of the challenges is having the availability of models that actually improve clinical care because we have some very early prospective trials on different devices, but we don’t have large-scale randomized clinical trials of AI devices showing definitive behaviors such as improved patient outcomes, that it helps curb skin cancer, or it catches it like dermatologists but helps reduce the biopsy load,” she said. “You need good data.”

Another challenge she noted was overcoming biases built into medicine. “A lot of the image-based models are built on datasets depicting skin disease on White skin, and those models don’t work so well on people with brown and black skin, who have historically had worse outcomes and also have been underrepresented in dermatology,” said Dr. Daneshjou, an associate editor of NEJM AI.

There’s also the challenge of getting verified AI models into the clinic. “Similar to many medical AI endeavors, developing a proof-of-concept or research prototype is far easier and faster than bringing the development to real users,” Dr. Liu said. “In particular, it is important to conduct thorough validation studies on various patient populations and settings and understand how these AI tools can best fit into the workflow or patient journey.”

A study published in 2023 documented progress Google made in deploying AI models in retina specialty clinics in India and Thailand, Dr. Liu noted.

Another challenge is to avoid overdiagnosis with these new technologies, Dr. Hartman said. Her group’s study showed the DermaSensor had a positive predictive value of 16% and a negative predictive value of 98.5%. “I think there’s some question about how this will factor into overdiagnosis. Could this actually bombard dermatologists more if the positive predictive value’s only 16%?”

One key to dermatologists accepting AI tools is having a transparent process for validating them, Dr. Lee said. “Even with FDA clearance, we don’t have the transparency we need as clinicians, researchers, and advocates of machine learning and AI in healthcare.”

But, Dr. Lee noted, the FDA in June took a step toward illuminating its validation process when it adopted guiding principles for transparency for machine learning–enabled devices. “Once we can get more access to this information and have more transparency, that’s where we can think about actually about making the decision to implement or not implement into local healthcare settings,” she said. The process was further enabled by a White House executive order in October 2023 on the safe, secure, and trustworthy development and use of AI.

The experience with telehealth during the COVID-19 pandemic, when patients and providers quickly embraced the technology to stay connected, serves as a potential template for AI, Dr. Lee noted. “As we’d seen with telehealth through the pandemic, you also need the cultural evolution and the development of the infrastructure around it to actually make sure this is a sustainable implementation and a scalable implementation in healthcare.”

Dr. Lee had no relevant relationships to disclose. Dr. Hartman received funding from DermaSensor for a study. Dr. Witkowski is a cofounder of Sklip. Dr. Liu is an employee of Google Research. Dr. Daneshjou reported financial relationships with MD Algorithms, Revea, and L’Oreal.

CARLSBAD, CALIFORNIA — The level of training and supervision among individuals who perform cosmetic procedures at medical spas (MedSpas) varies widely, a trend that patients may not be aware of, according to Sara Hogan, MD.

Dr. Sara Hogan

The top five cosmetic procedures offered by the 127 surveyed MedSpas were facials (85.0%), hair removal (85.0%), botulinum toxin injections (83.5%), dermal fillers (82.7%), and chemical peels (76.4%). About two thirds of cosmetic procedures were performed by aestheticians (66.9%), followed by registered nurses or licensed practical nurses (52.8%), board-certified physicians (48.8%, mostly plastic and reconstructive surgeons), nurse practitioners (27.6%), and physician assistants (9.4%).

In the realm of supervision, 16.5% of MedSpas surveyed reported that a medical director or supervising physician is always on site. “If not located on site, when asked where the physicians are, the majority of the time they were at the physician’s primary practice, clinic, or hospital,” Dr. Hogan said. “Only 65% of the MedSpas surveyed stated that they informed the patient that the supervising physician is not on site. In addition, a patient’s medical history is reviewed at only 40% of the MedSpas. To give context, in Illinois, a physician can only deliver care after a physician-patient relationship has been established, meaning that a good faith exam has been performed. And if they are to delegate any type of service, they must always be on site to provide assistance.”

Dr. Hogan noted that there are no federal statutes or agencies that regulate or oversee MedSpas. “Regulation and oversight are often delegated to state licensing agencies that are overwhelmed and often stretched thin regarding personnel and budgets,” she said. To raise awareness of this issue, the American Society for Dermatologic Surgery Association (ASDSA) launched the Medical Spa Safety Coalition, which aims to promote model legislation for states known as the Medical Spa Safety Act. Highlights of the bill include clear definitions of medical spa and medical director, as well as the requirement of an on-site medical director who must be a physician trained in all procedures performed at the MedSpa. Coalition members include 16 state dermatology boards as well as the ASDSA, the American Academy of Dermatology Association, the American Society for Laser Medicine & Surgery, and the American Society of Plastic Surgeons.

The ASDSA provided funding to support the published study. Dr. Hogan reported having no financial disclosures.

To the Editor:
Crusted scabies (formerly known as Norwegian scabies) is a rare and highly contagious variant of scabies, in which the skin is infested with thousands to millions of Sarcoptes scabiei var hominis mites. We present a case of skin changes that were misdiagnosed as atopic dermatitis, seborrhea, xerosis, and drug eruption on initial presentation, which prompted treatment with a corticosteroid that inadvertently caused progression to crusted scabies.

A 79-year-old woman who uses a wheelchair presented to the clinic with skin changes that consisted of diffuse, severely pruritic, erythematous plaques on the head, neck, trunk, face, and extremities of 2 years’ duration. She had a medical history of hyperlipidemia, hypertension, and hyperglycemia, as well as a stroke that required hospitalization 2 years prior to the onset of the skin changes. She had no history of allergies.

Prior clinical diagnoses by primary care and dermatology included xerosis, atopic dermatitis, seborrhea, and drug eruption. She was treated with a mid-potency topical corticosteroid (triamcinolone acetonide cream 0.1%) twice daily and prednisone 40 mg once daily for 2- to 4-week courses over an 8-month period without reduction in symptoms.

Physical examination at the current presentation revealed golden, crusted, fine, powdery but slightly sticky flakes that spread diffusely across the entire body and came off in crumbles with a simple touch. These widespread crusts were easily visible on clothing. There was underlying diffuse erythema beneath the flaking skin on the trunk and proximal extremities. The scale and shedding skin laid in piles on the patient’s lap and resembled brown sugar (Figure 1). The patient also reported decreased hand function and dexterity due to the yellowbrown, thick, crusty plaques that had developed on both the palmar and dorsal sides of the hands (Figure 2). Erythematous plaques on the scalp, forehead, and inner ears resembled seborrhea (Figure 3). Pruritus severity was rated by the patient as 10 of 10, and she scratched her skin the entire time she was in the clinic. The patient was emotional and stated that she had not been able to sleep due to the discomfort. We suspected scabies, and the patient was reassured to learn that it could be confirmed with a simple skin scrape test.

The crusted lesions on the patient's hands were scraped with a #15-blade scalpel, and a routine potassium hydroxide mount was performed. The skin scrapings were placed on a slide with a drop of 10% potassium hydroxide and observed under low-power (×10) and high-power (×40) microscopy, which revealed thousands of mites and eggs (along with previously hatched eggs) (Figure 4) and quickly confirmed a diagnosis of crusted scabies.an extremely contagious form of scabies seen in older patients with compromised immune systems, malnutrition, or disabilities. The patient was prescribed oral ivermectin (3 mg dosed at 200 μg/kg of body weight) and topical permethrin 5%, neither of which she took, as she died of a COVID-19 infection complication 3 days after this diagnostic clinic visit.

Classic and crusted scabies are both caused by infestation of the Sarcoptes scabiei var hominis mite. Classic scabies is a result of an infestation of a small number of mites (commonly 5–15 mites), while crusted scabies is due to hyperinfestation by as many as millions of mites, the latter often requiring more aggressive treatment. The mites are first transmitted to humans by either skin-toskin contact or fomites on bedding and clothing. The scabies mite undergoes 4 life cycle stages: egg, larvae, nymph, and adult. Once female mites are transmitted, they burrow under the skin and lay 2 to 3 eggs per day. The eggs hatch within 3 to 4 days, after which the larvae migrate to the skin surface. The larval stage lasts for 3 to 4 days, during which the larvae burrow into the stratum corneum to create molting pouches, until they molt into slightly larger nymphs. Nymphs can be found in hair follicles or molting pouches until they further molt within 3 to 4 days into adults, which are round, saclike mites. The adult male and female mites then mate, leaving the female fertile for the rest of her 1- to 2-month lifespan. Impregnated female mites traverse the skin surface in search of a burrow site, using the pulvilli on the anterior aspect of 2 legs to hold onto the skin. Once burrowed, the female mite continues to lay eggs for the rest of her life, with approximately 10% of her eggs resulting in adult mites. Male mites feed in shallow pits of the skin until they find a female burrow site for mating.¹ This continuous life cycle of the scabies mite gives rise to highly transmissible, pruritic skin excoriations, as demonstrated in our patient.

The skin has a relatively late inflammatory and adaptive immune response to scabies, typically occurring 4 to 6 weeks after the initial infestation.² This delayed inflammatory response and onset of symptoms may be due to the scabies mite’s ability to alter aspects of the host’s immune response, which differs in classic vs crusted scabies. In classic scabies, there is a predominance of CD4+ T cells in the dermis and minimal CD8+ T cells. The opposite is true in crusted scabies— there is an overwhelming infiltration of CD8+ T cells and minimal CD4+ T cells.³ The CD8+ T-cell predominance in crusted scabies is hypothesized to be the cause of keratinocyte apoptosis, resulting in epidermal hyperproliferation. Keratinocyte apoptosis also secretes cytokines, which may lead to the immunologic targeting of healthy skin cells. The damage of healthy dermal cells contributes to the inability of the skin’s immune system to mount an effective response, allowing the parasite to grow uncontrollably in patients with crusted scabies.⁴

This ineffective immune response is further exacerbated by corticosteroids, which are commonly prescribed for pruritus experienced by patients with scabies infestations. The mechanism of action of corticosteroids is the production of anti-inflammatory, antimitotic, and immunosuppressive effects.⁵ Because the integumentary immune system is imbalanced during crusted scabies infestation, the immunosuppressive mechanism of oral and topical corticosteroids further reduces the cellular immune response to scabies. The flourishing of the scabies mites along with keratinocyte apoptosis⁴ results in the development of hyperkeratotic skin crusting, most frequently on the palms, soles, arms, and legs. Risk factors for crusted scabies include immunosuppression, hospitalization, crowded living conditions, and poor hygiene, though no known risk factors were documented in up to 42% (33/78) of patients with crusted scabies in one study.⁶

Patients with crusted scabies typically present with generalized, poorly defined, erythematous, fissured plaques covered by scaling and crusts. Plaques on bony prominences such as finger articulations and elbows may have a thick verrucous aspect.¹ Skin flaking that resembles brown sugar—a mixture of white sugar and molasses—is a clue to the diagnosis of crusted scabies. Brown sugar has a slightly sandy and sticky texture that ranges in color from very light brown to very dark brown. When present, flakes always appears slightly lighter than the patient’s skin tone. Although skin burrows are pathognomonic and clinically recognizable features of scabies, these burrows can be disguised by lesions, such as the hyperkeratotic plaques seen in our patient. The lesions may or may not be associated with pruritus, which may occur only at night, and bacterial superinfection has been reported in severe cases of crusted scabies,⁷ as scratching can cause sores, which may lead to infection. In severe cases, the constant scratching could lead to sepsis if the infection enters the bloodstream.⁸ Another symptom of scabies is a rash that causes small bumps that tend to form in a line, resembling small bites, hives, or pimples, and scaly plaques can lead to misdiagnosis as atopic dermatitis.

Treatment often is delayed due to misdiagnosis, as seen in our patient. Common misdiagnoses include atopic dermatitis, pityriasis rosea, systemic lupus erythematosus, bullous pemphigoid, lichen planus, pediculosis corporis, seborrheic scalp dermatitis, and adverse drug reactions.⁹ Patients with extensive infestations of crusted scabies should be treated with a 4-week course of permethrin cream 5% daily for 1 week, then twice per week until resolved, and oral ivermectin 200 μg/kg dosed 1 week apart for up to 4 weeks, if needed.¹ Topical permethrin works by producing a selective neurotoxic effect on invertebrates such as scabies mites, which disrupts the function of voltage-gated sodium channels, thereby paralyzing the adult mites to halt the spread of infestation. However, treatment with topical medications can be difficult due to the thick crusts that have formed, which make it more challenging for the skin to properly absorb the treatment. Additionally, surgical debridement as an adjunct procedure has been done to improve the effectiveness of topical medications by removing all the mites in skin.¹⁰ On the other hand, the mechanism in which ivermectin treats scabies infestations is poorly understood. Current research suggests that ivermectin works by causing persistent opening of pH-gated chloride channels in scabies mites.¹¹ There is emerging concern for drug resistance to these scabicides,¹² revealing a need for further research of treatment options.

Patients with crusted scabies can have an extremely large number of mites (up to 2 million), making them more infectious than patients with classic scabies.¹³ As a result, it is imperative to reduce environmental transmission and risk for reinfection with mites during treatment. Because crusted scabies is transmitted by prolonged skinto- skin contact or by contact with personal items of an infected person (eg, bedding, clothing), treatment guidelines require all clothing, bedding, and towels of a patient with scabies to be machine-washed and dried with hot water and hot dryer cycles. If an item cannot be washed, it should be stored in a sealed plastic bag for 1 week, as scabies mites cannot survive more than 2 to 3 days away from their host of human skin.¹³ Treatment of close contacts of patients with scabies is recommended, as well as for those in endemic areas or closed communities, such as nursing homes or jails.

To the Editor:
Crusted scabies (formerly known as Norwegian scabies) is a rare and highly contagious variant of scabies, in which the skin is infested with thousands to millions of Sarcoptes scabiei var hominis mites. We present a case of skin changes that were misdiagnosed as atopic dermatitis, seborrhea, xerosis, and drug eruption on initial presentation, which prompted treatment with a corticosteroid that inadvertently caused progression to crusted scabies.

A 79-year-old woman who uses a wheelchair presented to the clinic with skin changes that consisted of diffuse, severely pruritic, erythematous plaques on the head, neck, trunk, face, and extremities of 2 years’ duration. She had a medical history of hyperlipidemia, hypertension, and hyperglycemia, as well as a stroke that required hospitalization 2 years prior to the onset of the skin changes. She had no history of allergies.

Prior clinical diagnoses by primary care and dermatology included xerosis, atopic dermatitis, seborrhea, and drug eruption. She was treated with a mid-potency topical corticosteroid (triamcinolone acetonide cream 0.1%) twice daily and prednisone 40 mg once daily for 2- to 4-week courses over an 8-month period without reduction in symptoms.

Physical examination at the current presentation revealed golden, crusted, fine, powdery but slightly sticky flakes that spread diffusely across the entire body and came off in crumbles with a simple touch. These widespread crusts were easily visible on clothing. There was underlying diffuse erythema beneath the flaking skin on the trunk and proximal extremities. The scale and shedding skin laid in piles on the patient’s lap and resembled brown sugar (Figure 1). The patient also reported decreased hand function and dexterity due to the yellowbrown, thick, crusty plaques that had developed on both the palmar and dorsal sides of the hands (Figure 2). Erythematous plaques on the scalp, forehead, and inner ears resembled seborrhea (Figure 3). Pruritus severity was rated by the patient as 10 of 10, and she scratched her skin the entire time she was in the clinic. The patient was emotional and stated that she had not been able to sleep due to the discomfort. We suspected scabies, and the patient was reassured to learn that it could be confirmed with a simple skin scrape test.

The crusted lesions on the patient's hands were scraped with a #15-blade scalpel, and a routine potassium hydroxide mount was performed. The skin scrapings were placed on a slide with a drop of 10% potassium hydroxide and observed under low-power (×10) and high-power (×40) microscopy, which revealed thousands of mites and eggs (along with previously hatched eggs) (Figure 4) and quickly confirmed a diagnosis of crusted scabies.an extremely contagious form of scabies seen in older patients with compromised immune systems, malnutrition, or disabilities. The patient was prescribed oral ivermectin (3 mg dosed at 200 μg/kg of body weight) and topical permethrin 5%, neither of which she took, as she died of a COVID-19 infection complication 3 days after this diagnostic clinic visit.

When Andrea Austin, MD, an emergency medicine specialist, left the military in 2020, she knew the adjustment to civilian life and practice might be difficult. To help smooth the transition, she reached out to a physician mentor who also had a professional coaching certificate. After a conversation, Dr. Austin signed up for 6 months of career coaching. 

It was time well spent, according to Dr. Austin, who today is a coach herself. “It was really the first time I had the ability to choose what I wanted to do, and that required a mindset shift,” she explains. “A big part of coaching is helping physicians discover their agency so that they can make the best career choices.”

Physicians have long lacked the coaching resources typically made available to corporate executives. But that’s changing. In today’s high-pressure environment, where doctors are burning out at a rapid pace, coaching can sometimes be an avenue to staying in the field, especially if that coach is a fellow physician who understands what you’re facing. 

With a physician shortage that the Association of American Medical Colleges expects to hit 86,000 in the next decade or so, coaching could be a stone worth turning over. A 2024 report in JAMA Network Open found that coaching provided by physician peers led to a significant reduction in interpersonal disengagement and burnout. 

“What I think is exciting about coaching is that it allows you to better understand yourself and know your strengths and weaknesses,” said Dr. Austin. “It might seem simple, but many ‘soft skills’ aren’t considered mainstream in medicine. Coaching allows us to understand them and ourselves better.” 
 

Why Are Doctors Using Coaches?

Although it’s hard to put a number on how many physicians are turning to coaches, the number of coaches available for doctors is growing rapidly. The American Medical Women’s Association maintains a database of physician coaches. According to deputy director Jodi Godfrey, MS, RDN, the number of members who have added coaching to their skill set has tripled in the past 4 years. “Many cite burnout as the reason they sought coaching support, and then they decided to go on to get certified in coaching.”

The pandemic is one reason physician coaching has grown, said Elizabeth Esparaz, MD, an ophthalmologist and physician coach. “Since the pandemic, the word ‘burnout’ is thrown around a good deal.” And the causes are clear. “Doctors are facing longer hours, they must make split-second decisions, they’re multitasking, and they have less support staff.”

Among her coaching clients, Dr. Austin has noticed other common struggles: fears of litigation, time scarcity with patients, declining reimbursement that hasn’t kept up with inflation, and loss of autonomy because of the corporatization of healthcare. 

Coaching, Dr. Esparaz believes, can be an antidote to many of these issues. “Coaches help doctors see their strengths and find better ways of applying them,” she said. “We help them move forward, and also see their blind spots.”
 

Clarity, Goals, and Making the Right Choices

Physician coaching comes in a variety of flavors — some one on one, and others in the form of group sessions. All, however, serve the purpose of helping physicians gain career clarity. “Sometimes clients realize their job may not be working for them, but that there are things they can do to change that without having to leave the field,” said Jattu Senesie, MD, a former ob.gyn. who is now a physician coach. 

Dr. Esparaz works with doctors to establish SMART goals: specific, measurable, attainable, realistic, and time based. She gave the example of learning how to set boundaries. “If a physician is asked to create a presentation for work, I encourage them to ask for compensation or administrative time before committing to unpaid tasks.”

Another big issue: charting. It’s increasingly burdensome, and many doctors find it encroaching on their home lives. “If we can identify a problem like that, we can come up with a strategy for mitigating it,” Dr. Esparaz said. This might include setting a goal of getting 80% of charting completed immediately after the patient encounter on the busiest clinic day of the week. The client tests the experiment and then revisits it with the coach to discuss what worked and what didn’t, refining the process until it has freed up the physician’s home life.

The younger generation of doctors often struggles with career choices, too, because it’s the first time they are without structure, said Dr. Senesie. There’s med school and residency, which puts a framework around every move a doctor makes. But once they become attending physicians, the choices are endless. “Coaching can help them find a new structure and systems that will allow them to thrive.”

Although mentoring has been a well-embraced concept for decades, it “hits a wall,” at some point in terms of what it can offer, Dr. Austin said. That’s where coaching can take over. “There’s a point where a mentor cannot help someone self-actualize. As a coach, you don’t need to know everything about a doctor’s life, but you can help them learn to ask themselves the right questions to solve problems.”
 

Should You Stay or Should You Go?

Dr. Austin’s approach begins with the premise that healthcare today is challenging and dysfunctional — but doctors still have agency. She has worked with clients on the verge of leaving the field and helped them find their way back. 

“They have a light bulb moment and open up to the idea that they have much to give still,” she said. “We take an inventory to help them better communicate their needs and make changes, and I help them connect to their values. Sometimes that exercise allows them to reframe their current work environment.” 

Not every doctor who goes through coaching remains in the field. But “that’s the exception, not the rule,” Dr. Austin said. And that’s okay. “If that’s the outcome, coaching probably helped them get to that point faster, and with an informed decision.” 

Dr. Senesie has been coaching for about a decade, and in that time, she’s seen a shift that goes beyond figuring out career goals. “Doctors are more aware of the need for well-being today. The pandemic made it impossible to ignore what doesn’t work for us. When I work with clients, we look for ways to make the job more tenable.” 

According to Dr. Senesie, younger doctors are looking for that balance at the outset. “They want to be physicians, but they also want a life,” she said. “It’s a challenge for them because in addition to that mindset, they’re also coming out with more debt than older generations. They want out from underneath that.”
 

When It’s Time to Find a Physician Coach

Wondering whether coaching is right for you? Consider these symptoms:

• You need help setting boundaries at work.
• You feel like you’re sacrificing your own well-being for your job.
• You’re using maladaptive strategies to cope with the stress at work.
• You’ve reached a point where you are considering leaving the field.

If you’re interested in finding a physician coach, there are several places to begin your search, word of mouth being one of them. “Conferences and social media can also expose you to coaches,” suggested Dr. Esparaz. There are different methods and approaches to coaching. So, as you research, “make sure the coach you choose has techniques and a framework that fit what you’re after.” 

Dr. Austin warned that it is an unregulated industry, so buyer beware. To ensure you’re getting an accredited physician coach, look for people who have obtained an International Coach Federation (ICF) accreditation. These coaches will hold an associate certified coach credential, which requires at least 60 hours of coaching-specific training approved by the ICF, in addition to other assessments and education. 

Ensure that the coach you choose is within your budget. “There are some people charging astronomical rates out there,” Dr. Austin said. “If you’re burned out or struggling, it can be easy to reach for your credit card.”

Dr. Austin also cautioned doctors seeking a coach to avoid promises that sound too good to be true. Some coaching can have a gaslighting quality to it, she warned, “suggesting it can allow you to endure any environment.” But positive self-talk alone won’t cure an abusive or discriminatory situation. “If a client describes a toxic work environment,” the coach has an “ethical imperative” to help that person protect themselves.

After Dr. Austin’s experience with her coach, she made the choice to continue as an emergency physician part-time while starting her own coaching business. “It’s important for me personally to keep in touch with what’s happening on the ground, but I have no judgment for anyone who chooses to leave clinical practice to become a coach.”

When Dr. Senesie looks back on her own struggles as a clinician, she recognizes the state of burnout she was in 10 years ago. “I knew there was an issue, but I didn’t have the mindset to find a way to make it work,” she said. “I left the field when I was at my depths of burnout, which is generally not the best way to go about it.” 

Guidance might have allowed her to take into account other avenues and helped her remain in the field, said Dr. Senesie. She has since learned that “there are many ways to practice medicine, and the way we’ve gone about it traditionally has worked for some, but not necessarily for everyone.” 

There may be more possibilities than you think. By helping you assess your path and make meaningful changes, a physician coach might be the key to remaining in the field you love.

When Andrea Austin, MD, an emergency medicine specialist, left the military in 2020, she knew the adjustment to civilian life and practice might be difficult. To help smooth the transition, she reached out to a physician mentor who also had a professional coaching certificate. After a conversation, Dr. Austin signed up for 6 months of career coaching. 

It was time well spent, according to Dr. Austin, who today is a coach herself. “It was really the first time I had the ability to choose what I wanted to do, and that required a mindset shift,” she explains. “A big part of coaching is helping physicians discover their agency so that they can make the best career choices.”

Physicians have long lacked the coaching resources typically made available to corporate executives. But that’s changing. In today’s high-pressure environment, where doctors are burning out at a rapid pace, coaching can sometimes be an avenue to staying in the field, especially if that coach is a fellow physician who understands what you’re facing. 

With a physician shortage that the Association of American Medical Colleges expects to hit 86,000 in the next decade or so, coaching could be a stone worth turning over. A 2024 report in JAMA Network Open found that coaching provided by physician peers led to a significant reduction in interpersonal disengagement and burnout. 

“What I think is exciting about coaching is that it allows you to better understand yourself and know your strengths and weaknesses,” said Dr. Austin. “It might seem simple, but many ‘soft skills’ aren’t considered mainstream in medicine. Coaching allows us to understand them and ourselves better.” 
 

Why Are Doctors Using Coaches?

Although it’s hard to put a number on how many physicians are turning to coaches, the number of coaches available for doctors is growing rapidly. The American Medical Women’s Association maintains a database of physician coaches. According to deputy director Jodi Godfrey, MS, RDN, the number of members who have added coaching to their skill set has tripled in the past 4 years. “Many cite burnout as the reason they sought coaching support, and then they decided to go on to get certified in coaching.”

The pandemic is one reason physician coaching has grown, said Elizabeth Esparaz, MD, an ophthalmologist and physician coach. “Since the pandemic, the word ‘burnout’ is thrown around a good deal.” And the causes are clear. “Doctors are facing longer hours, they must make split-second decisions, they’re multitasking, and they have less support staff.”

Among her coaching clients, Dr. Austin has noticed other common struggles: fears of litigation, time scarcity with patients, declining reimbursement that hasn’t kept up with inflation, and loss of autonomy because of the corporatization of healthcare. 

Coaching, Dr. Esparaz believes, can be an antidote to many of these issues. “Coaches help doctors see their strengths and find better ways of applying them,” she said. “We help them move forward, and also see their blind spots.”
 

Clarity, Goals, and Making the Right Choices

Physician coaching comes in a variety of flavors — some one on one, and others in the form of group sessions. All, however, serve the purpose of helping physicians gain career clarity. “Sometimes clients realize their job may not be working for them, but that there are things they can do to change that without having to leave the field,” said Jattu Senesie, MD, a former ob.gyn. who is now a physician coach. 

Dr. Esparaz works with doctors to establish SMART goals: specific, measurable, attainable, realistic, and time based. She gave the example of learning how to set boundaries. “If a physician is asked to create a presentation for work, I encourage them to ask for compensation or administrative time before committing to unpaid tasks.”

Another big issue: charting. It’s increasingly burdensome, and many doctors find it encroaching on their home lives. “If we can identify a problem like that, we can come up with a strategy for mitigating it,” Dr. Esparaz said. This might include setting a goal of getting 80% of charting completed immediately after the patient encounter on the busiest clinic day of the week. The client tests the experiment and then revisits it with the coach to discuss what worked and what didn’t, refining the process until it has freed up the physician’s home life.

The younger generation of doctors often struggles with career choices, too, because it’s the first time they are without structure, said Dr. Senesie. There’s med school and residency, which puts a framework around every move a doctor makes. But once they become attending physicians, the choices are endless. “Coaching can help them find a new structure and systems that will allow them to thrive.”

Although mentoring has been a well-embraced concept for decades, it “hits a wall,” at some point in terms of what it can offer, Dr. Austin said. That’s where coaching can take over. “There’s a point where a mentor cannot help someone self-actualize. As a coach, you don’t need to know everything about a doctor’s life, but you can help them learn to ask themselves the right questions to solve problems.”
 

Should You Stay or Should You Go?

Dr. Austin’s approach begins with the premise that healthcare today is challenging and dysfunctional — but doctors still have agency. She has worked with clients on the verge of leaving the field and helped them find their way back. 

“They have a light bulb moment and open up to the idea that they have much to give still,” she said. “We take an inventory to help them better communicate their needs and make changes, and I help them connect to their values. Sometimes that exercise allows them to reframe their current work environment.” 

Not every doctor who goes through coaching remains in the field. But “that’s the exception, not the rule,” Dr. Austin said. And that’s okay. “If that’s the outcome, coaching probably helped them get to that point faster, and with an informed decision.” 

Dr. Senesie has been coaching for about a decade, and in that time, she’s seen a shift that goes beyond figuring out career goals. “Doctors are more aware of the need for well-being today. The pandemic made it impossible to ignore what doesn’t work for us. When I work with clients, we look for ways to make the job more tenable.” 

According to Dr. Senesie, younger doctors are looking for that balance at the outset. “They want to be physicians, but they also want a life,” she said. “It’s a challenge for them because in addition to that mindset, they’re also coming out with more debt than older generations. They want out from underneath that.”
 

When It’s Time to Find a Physician Coach

Wondering whether coaching is right for you? Consider these symptoms:

• You need help setting boundaries at work.
• You feel like you’re sacrificing your own well-being for your job.
• You’re using maladaptive strategies to cope with the stress at work.
• You’ve reached a point where you are considering leaving the field.

If you’re interested in finding a physician coach, there are several places to begin your search, word of mouth being one of them. “Conferences and social media can also expose you to coaches,” suggested Dr. Esparaz. There are different methods and approaches to coaching. So, as you research, “make sure the coach you choose has techniques and a framework that fit what you’re after.” 

Dr. Austin warned that it is an unregulated industry, so buyer beware. To ensure you’re getting an accredited physician coach, look for people who have obtained an International Coach Federation (ICF) accreditation. These coaches will hold an associate certified coach credential, which requires at least 60 hours of coaching-specific training approved by the ICF, in addition to other assessments and education. 

Ensure that the coach you choose is within your budget. “There are some people charging astronomical rates out there,” Dr. Austin said. “If you’re burned out or struggling, it can be easy to reach for your credit card.”

Dr. Austin also cautioned doctors seeking a coach to avoid promises that sound too good to be true. Some coaching can have a gaslighting quality to it, she warned, “suggesting it can allow you to endure any environment.” But positive self-talk alone won’t cure an abusive or discriminatory situation. “If a client describes a toxic work environment,” the coach has an “ethical imperative” to help that person protect themselves.

CARLSBAD, CALIFORNIA — In 2003, researchers asked 303 patients with systemic sclerosis (scleroderma) what bothered them most about their disease from an aesthetic standpoint: Orofacial features, such as thin lips and mouth furrows, or non-facial features, such as fingertip ulceration and waxy changes to the skin.

Respondents expressed significant concern about specific orofacial features, including thin lips (73%), mouth furrows (80%), loss of facial lines (68%), and a smaller, tighter mouth (77%).

“Patients with systemic sclerosis may have loss of vermilion lip, microstomia, and perioral rhytids,” Kathleen Cook Suozzi, MD, who directs the Aesthetic Dermatology Program at Yale University School of Medicine, New Haven, Connecticut, said at the Controversies and Conversations in Laser and Cosmetic Surgery annual symposium. “How can we address these changes for our patients?”

Yale University School of Medicine

Recent research has shown that hyaluronidase injections can help improve orofacial changes commonly experienced by patients with scleroderma. In 2019, researchers in Alabama reported the case of a 53-year-old woman treated with hyaluronidase for scleroderma-induced microstomia. After four visits over 7 months and a total hyaluronidase dose of 470 IU, the patient reported an improved Mouth Handicap in Systemic Sclerosis (MHISS) score (38 of 48); subjective improvement of symptoms, including greater ease in eating and undergoing dental treatment; and improved mouth closure.

In 2023, researchers published a cohort study of four women between the ages of 43 and 61 with autoimmune sclerosing conditions that resulted in oral microstomia. Following hyaluronidase injections, all improved in mouth opening capacity and MHISS, with change stabilizing between three and five treatments. More recently, in a study pending publication in JAAD Case Reports, Dr. Suozzi and colleagues retrospectively evaluated 12 women with scleroderma who received between 150 and 300 units of hyaluronic acid (HA) filler for microstomia between 2020 and 2023. Of the 12 women, 58% had diffuse disease, and 42% had limited disease. Overall, oral aperture width increased by 0.65 cm (P = .0027) and oral aperture height increased by 0.88 cm (P < .0001). “In general, patients needed three to four treatments to reach peak effect, and then they reached a plateau,” Dr. Suozzi said. “It wasn’t that the treatment wasn’t working anymore, but it was because their oral aperture had gotten to a size of around 5 cm, which is clinically normal. Interestingly, we found that if the patient’s disease flared and their microstomia started to return, when you rechallenged them, they continued to respond. So, patients can continue to use this treatment over time.”

In a separate case series of seven patients, Dr. Suozzi and colleagues prospectively evaluated the effect of HA soft tissue filler with Restylane Silk for lip augmentation. Study participants experienced statistically significant increases in the difference between pre- and postinjection fullness in both upper and lower lips. Also, the mean posttreatment score fell between “much improved” (2) and “improved” (3) on both the Investigator Global Aesthetic Improvement Scale and the Subject Global Aesthetic Improvement Scale.

Dr. Suozzi recommends using nerve blocks for injecting HA filler or hyaluronidase in patients with scleroderma and minimizing the injection points. “Initially, we were using 30% lidocaine preparations around the mouth for an hour before the procedure, and patients were still having pain, so now we use nerve blocks,” she said. “For hyaluronidase, we do perform a test dose of 75-100 units, usually in the commissure. It’s amazing how well it works; people will usually come back after their test dose and have improvements in their measurements. This is a really easy treatment to perform, and I think it can be done in the office of a general dermatologist. There is concern about cross-reactivity with bee venom, so you want to ask patients about that.”

Dr. Suozzi reported having no relevant financial relationships.

Given the clinical presentation and the absence of other systemic or dermatological findings, the diagnosis of chevron nails was made.

Discussion

Chevron nails, also known as V-shaped nails or herringbone nails, are an uncommon but benign nail condition typically observed in infancy and early childhood. The condition is characterized by transverse ridges on the nails that converge towards the center, forming a V or chevron shape. This condition was first described by Perry et al. and later by Shuster et al., who explained that the condition might result from axial growth of the nail with synchronous growth occurring from a chevron-shaped growing edge of the nail root. Alternatively, Shuster suggested that sequential growth, with localized variation in the nail production rate, could propagate a wave from the center of the nail to the edge.

The etiology of chevron nails is not well understood, but it is believed to result from temporary disruptions in the nail matrix, possibly related to minor illness or physiological stress during infancy.

In the case of our 7-month-old patient, the history of mild upper respiratory infections might have contributed to the development of chevron nails. However, the lack of other significant illness, skin involvement, or systemic findings supports the benign and self-limiting nature of this condition. Parents were reassured that chevron nails typically resolve on their own as the child grows and that no specific treatment is necessary.
 

Differential Diagnosis

The differential diagnosis of transverse nail changes in children includes other conditions such as trachyonychia, lichen planus, Darier disease, and pachyonychia congenita.

Trachyonychia, also known as “sandpaper nails,” trachyonychia is characterized by the roughening of the nail surface, giving it a dull and ridged appearance. The condition may affect all 20 nails and is often associated with underlying dermatological conditions such as lichen planus or alopecia areata. Unlike chevron nails, trachyonychia presents with more diffuse nail changes and does not typically feature the distinct V-shaped ridging seen in this patient.

Lichen planus is an inflammatory condition that can affect the skin, mucous membranes, and nails. Nail involvement in lichen planus can lead to longitudinal ridging, thinning, and sometimes even complete nail loss. The absence of other characteristic features of lichen planus, such as violaceous papules on the skin or white lacy patterns on mucous membranes (Wickham striae), makes this diagnosis less likely in our patient.

Darier disease, also known as keratosis follicularis, is a genetic disorder characterized by greasy, warty papules primarily on seborrheic areas of the skin, nail abnormalities, and sometimes mucosal involvement. Nail changes in Darier disease include longitudinal red and white streaks, V-shaped notching at the free edge of the nails, and subungual hyperkeratosis. These nail changes are more severe and distinct than the simple transverse ridging seen in chevron nails. The absence of other clinical signs of Darier disease, such as skin papules or characteristic nail notching, makes this diagnosis unlikely in our patient.

Pachyonychia congenita is a rare genetic disorder characterized by thickened nails (pachyonychia), painful plantar keratoderma, and sometimes oral leukokeratosis. The condition typically presents with significant nail thickening and other systemic findings, which were absent in our patient. The distinct pattern of V-shaped ridging observed in chevron nails does not align with the typical presentation of pachyonychia congenita.
 

Next Steps

No specific treatment is required for chevron nails. The condition is typically self-resolving, and the nails usually return to a normal appearance as the child continues to grow. Parents were advised to monitor the nails for any changes or new symptoms and were reassured about the benign nature of the findings. Follow-up was scheduled to ensure the resolution of the condition as the child develops.

Conclusion

Chevron nails are an important consideration in the differential diagnosis of transverse nail ridging in infants and young children. While the condition is benign and self-limiting, it is crucial to differentiate it from other nail dystrophies, such as trachyonychia, lichen planus, Darier disease, and pachyonychia congenita, which may require further investigation or intervention. Awareness of chevron nails can help prevent unnecessary worry and provide reassurance to parents and caregivers.

Given the clinical presentation and the absence of other systemic or dermatological findings, the diagnosis of chevron nails was made.

Discussion

Chevron nails, also known as V-shaped nails or herringbone nails, are an uncommon but benign nail condition typically observed in infancy and early childhood. The condition is characterized by transverse ridges on the nails that converge towards the center, forming a V or chevron shape. This condition was first described by Perry et al. and later by Shuster et al., who explained that the condition might result from axial growth of the nail with synchronous growth occurring from a chevron-shaped growing edge of the nail root. Alternatively, Shuster suggested that sequential growth, with localized variation in the nail production rate, could propagate a wave from the center of the nail to the edge.

The etiology of chevron nails is not well understood, but it is believed to result from temporary disruptions in the nail matrix, possibly related to minor illness or physiological stress during infancy.

In the case of our 7-month-old patient, the history of mild upper respiratory infections might have contributed to the development of chevron nails. However, the lack of other significant illness, skin involvement, or systemic findings supports the benign and self-limiting nature of this condition. Parents were reassured that chevron nails typically resolve on their own as the child grows and that no specific treatment is necessary.
 

Differential Diagnosis

The differential diagnosis of transverse nail changes in children includes other conditions such as trachyonychia, lichen planus, Darier disease, and pachyonychia congenita.

Trachyonychia, also known as “sandpaper nails,” trachyonychia is characterized by the roughening of the nail surface, giving it a dull and ridged appearance. The condition may affect all 20 nails and is often associated with underlying dermatological conditions such as lichen planus or alopecia areata. Unlike chevron nails, trachyonychia presents with more diffuse nail changes and does not typically feature the distinct V-shaped ridging seen in this patient.

Lichen planus is an inflammatory condition that can affect the skin, mucous membranes, and nails. Nail involvement in lichen planus can lead to longitudinal ridging, thinning, and sometimes even complete nail loss. The absence of other characteristic features of lichen planus, such as violaceous papules on the skin or white lacy patterns on mucous membranes (Wickham striae), makes this diagnosis less likely in our patient.

Darier disease, also known as keratosis follicularis, is a genetic disorder characterized by greasy, warty papules primarily on seborrheic areas of the skin, nail abnormalities, and sometimes mucosal involvement.

TOPLINE: 

Patients with psoriasis, uveitis, or colitis who present with undiagnosed chronic back pain should be referred to a rheumatologist for the assessment of axial spondyloarthritis (axSpA), with MRI being a more accurate diagnostic method than clinical features.

METHODOLOGY:

• Researchers assessed the prevalence of axSpA according to the extra-articular presentation and human leukocyte antigen B27 (HLA-B27) status in two Canadian cohorts (SASPIC 1 and 2).
• Overall, 363 adult patients aged ≤ 45 years with psoriasis, uveitis, or colitis who presented with chronic undiagnosed back and/or buttock pain lasting 3 months or more were included.
• Participants were referred to rheumatologists with expertise in axSpA for structured diagnostic evaluations, including history, physical exam, levels of C-reactive protein, HLA-B27 status, and imaging studies.
• An MRI of the sacroiliac joints was conducted in all patients in the SASPIC-2 cohort and in 62.3% of those in the SASPIC-1 cohort.
• The primary outcome was the proportion of patients diagnosed with axSpA after final global evaluation, and the secondary outcome was the impact of MRI on diagnosis and classification.

TAKEAWAY:

• AxSpA diagnoses were made in 46.7% with psoriasis, 61.6% with uveitis, and 46.8% with colitis in the SASPIC-1 cohort and in 23.5%, 57.9%, and 23.3%, respectively, in the SASPIC-2 cohort.
• Being positive for HLA-B27 was linked to the presence of axSpA in 56%-88% of those in both the cohorts.
• Musculoskeletal clinical features were not helpful in differentiating between patients with and without axSpA.
• In both the cohorts, the MRI of the sacroiliac joints was indicative of axSpA in a significantly greater number of patients with psoriasis, uveitis, or colitis who were diagnosed with axSpA than in those not diagnosed with axSpA (P < .05 for all).

IN PRACTICE:

“Our data supports the benefit of recent referral recommendations that advocate referral to a rheumatologist of patients with chronic back pain and extra-articular features related to axSpA,” the authors wrote.

SOURCE:

The study was led by Walter P. Maksymowych, MB ChB, University of Alberta, Edmonton, Alberta, Canada. It was published online in Arthritis & Rheumatology.

LIMITATIONS: 

MRI readers had to rely on their own expertise to decide if an MRI was indeed positive and thus indicative of axSpA. This study included only patients with undiagnosed back pain, and a longer follow-up duration could have led to a higher number of patients being diagnosed with axial inflammation. In SASPIC-1, local rheumatologists conducted MRI evaluations of the spinal lesions only when necessary, while in SASPIC-2, MRI of only the sacroiliac joints was required.

DISCLOSURES:

SASPIC-1 was supported by AbbVie Canada and Janssen Canada, and SASPIC-2 was supported by AbbVie Canada. The authors disclosed receiving grants, consulting fees, speaking fees, and/or honoraria and having other ties with AbbVie and several other pharmaceutical companies.

Rising consolidation among pharmacy benefit managers (PBMs) allows the companies to profit at the expense of patients and independent pharmacists. That’s the conclusion of a recent Federal Trade Commission (FTC) report on interim findings from the agency’s ongoing investigation of PBMs. 

Lawmakers are increasingly scrutinizing the industry amid growing concern among physicians and consumers about how PBMs exploit their market dominance. The top six PBMs managed 94% of US drug claims in 2023, with the majority handled by the industry’s three giants: CVS Caremark, Cigna’s Express Scripts, and United Healthcare’s OptumRx.

PBMs manage prescription drug benefits for health insurers, Medicare Part D drug plans, and large employers. They act as middlemen between health insurers and pharmacies, developing formularies of covered drugs and promising savings from the discounts and rebates they negotiate with drugmakers.

The FTC’s interim report found that the giant PBMs often exercise significant control over what drugs are available and at what price and which pharmacies patients can use to access their prescribed medications. Consumers suffer as a result, the report concluded.

Madelaine A. Feldman, MD, vice president for advocacy and government affairs for the Coalition of State Rheumatology Organizations, shared her perspective on the FTC report in an email Q&A with this news organization. She is affiliated with The Rheumatology Group, based in Metairie, Louisiana. 

Dr. Feldman has long tracked the PBM industry and appeared as a witness before influential government panels, including the House Energy and Commerce Committee. She has highlighted for lawmakers the challenges physicians face in helping patients get needed medicines. 

For example, she shared cases of PBMs steering patients toward the more expensive of three widely used rheumatoid arthritis medicines that have a similar mechanism of action, the Janus kinase (JAK) inhibitors, Dr. Feldman said. 

One of the drugs cost roughly half of the other two — about $30,000 per year vs $65,000-$70,000. Yet only the two expensive drugs were included in the PBM formulary. As a result, the cheapest drug holds only a sliver of market share; the remainder is dominated by the two expensive products, she told the House Oversight and Accountability Committee in 2021.

This Q&A has been edited for length and clarity.

What would you want federal and state policymakers to do in response to the FTC’s report?

I think Congress needs to clearly delineate the differences between anticompetitive pharmacy issues, drug pricing issues, and their effect on formulary construction issues.

Lawmakers should demand more transparency and consider legislation that would remove perverse incentives that prompt PBMs to choose higher priced drugs for their formularies. 

That may require other regulatory or legislative actions to ensure lower prices (not higher kickbacks) are incentivized. Ultimately, in order to gain true competition within the health insurance business, these oligopolies of multiple businesses need to be broken up. Anything less seems to be nibbling around the edges and allows the Big Three to continue their “whack-a mole” in circumventing piecemeal regulatory and legislative policies.

You’ve followed PBM practices closely for many years. Was there anything in this interim FTC report that surprised you?

Though not surprised, I am glad that it was released because it had been a year in investigation and there were many requests for some type of substantive report. 

Two things that are missing that I feel are paramount are investigating how the three big PBMs are causing physical harm to patients as a result of the profit component in formulary construction and the profound financial impact of hidden PBM profit centers in self-insured employer health plans.

What we have seen over the years is the result of the perverse incentives for the PBMs to prefer the most profitable medications on their formularies. 

They use utilization management tools such as step therapy, nonmedical switching, and exclusions to maintain their formularies’ profitability. These tools have been shown to delay and deny the proper care of patients, resulting in not just monetary but physical harm as well. 

I would think the physical harm done to patients in manipulating the formularies should be addressed in this report as well and, in fact, may be the most important aspect of consumer protection of this issue.

In terms of the FTC’s mission to not “unduly burden” legitimate business, I would like to see the sector of self-insured employers addressed. 

The report details how PBMs steer prescriptions to their affiliated pharmacies. The FTC says that can push smaller pharmacies out of the market, ultimately leading to higher costs and lower quality services for people. What’s your perspective? 

Having more community pharmacies is better than having less. We are seeing more “pharmacy deserts” in rural areas as a result of many community pharmacies having to close.

The FTC voted 4-1 to allow staff to issue the interim report, with Commissioner Melissa Holyoak voting no. And some FTC commissioners seem divided on the usefulness of the report. Why?

Commissioner Holyoak states the “the Report leaves us without a better understanding of the competition concerns surrounding PBMs or how consumers are impacted by PBM practices.” 

I do agree with her that the harm to patients’ medical status was not even addressed as far as I could tell in this report. There are multiple news articles and reports on the harms inflicted upon patients by the UM tools that drive the construction of ever changing formularies, all based on contracting with manufacturers that result in the highest profit for the PBM.

Holyoak also states, “Among other critical conclusions, the Report does not address the seemingly contradictory conclusions in the 2005 Report that PBMs, including vertically owned PBMs, generated cost savings for consumers.” 

That may be true, but in 2005, the rise of PBMs was just beginning and the huge vertical and horizontal integration had yet to begin. Also, 2005 was still in the beginning of the biologic drug deluge, which did create competition to get on the formulary. Since then, PBMs have done nothing to control the rise in prices but instead, apparently have used the competition to get higher price concessions from manufacturers based on a percentage of the list price to line their pockets.

Commissioner Ferguson agreed with releasing the report but he had many issues with this report including the lack of PBM response. 

I do agree with him that the FTC should have used some type of “force” to get the information they needed from the PBMs. The Big Three are known for obfuscation and delaying providing information to legislative and regulatory agencies.

The FTC voted 4-1 to allow staff to issue the interim report, with Commissioner Melissa Holyoak voting no. And some FTC commissioners seem divided on the usefulness of the report. Why?

Commissioner Holyoak states the “the Report leaves us without a better understanding of the competition concerns surrounding PBMs or how consumers are impacted by PBM practices.” 

I do agree with her that the harm to patients’ medical status was not even addressed as far as I could tell in this report. There are multiple news articles and reports on the harms inflicted upon patients by the UM tools that drive the construction of ever changing formularies, all based on contracting with manufacturers that result in the highest profit for the PBM.

Holyoak also states, “Among other critical conclusions, the Report does not address the seemingly contradictory conclusions in the 2005 Report that PBMs, including vertically owned PBMs, generated cost savings for consumers.” 

That may be true, but in 2005, the rise of PBMs was just beginning and the huge vertical and horizontal integration had yet to begin. Also, 2005 was still in the beginning of the biologic drug deluge, which did create competition to get on the formulary. Since then, PBMs have done nothing to control the rise in prices but instead, apparently have used the competition to get higher price concessions from manufacturers based on a percentage of the list price to line their pockets.

Commissioner Ferguson agreed with releasing the report but he had many issues with this report including the lack of PBM response. 

I do agree with him that the FTC should have used some type of “force” to get the information they needed from the PBMs. The Big Three are known for obfuscation and delaying providing information to legislative and regulatory agencies.

Rising consolidation among pharmacy benefit managers (PBMs) allows the companies to profit at the expense of patients and independent pharmacists. That’s the conclusion of a recent Federal Trade Commission (FTC) report on interim findings from the agency’s ongoing investigation of PBMs. 

Lawmakers are increasingly scrutinizing the industry amid growing concern among physicians and consumers about how PBMs exploit their market dominance. The top six PBMs managed 94% of US drug claims in 2023, with the majority handled by the industry’s three giants: CVS Caremark, Cigna’s Express Scripts, and United Healthcare’s OptumRx.

PBMs manage prescription drug benefits for health insurers, Medicare Part D drug plans, and large employers. They act as middlemen between health insurers and pharmacies, developing formularies of covered drugs and promising savings from the discounts and rebates they negotiate with drugmakers.

The FTC’s interim report found that the giant PBMs often exercise significant control over what drugs are available and at what price and which pharmacies patients can use to access their prescribed medications. Consumers suffer as a result, the report concluded.

Madelaine A. Feldman, MD, vice president for advocacy and government affairs for the Coalition of State Rheumatology Organizations, shared her perspective on the FTC report in an email Q&A with this news organization. She is affiliated with The Rheumatology Group, based in Metairie, Louisiana. 

Dr. Feldman has long tracked the PBM industry and appeared as a witness before influential government panels, including the House Energy and Commerce Committee. She has highlighted for lawmakers the challenges physicians face in helping patients get needed medicines. 

For example, she shared cases of PBMs steering patients toward the more expensive of three widely used rheumatoid arthritis medicines that have a similar mechanism of action, the Janus kinase (JAK) inhibitors, Dr. Feldman said. 

One of the drugs cost roughly half of the other two — about $30,000 per year vs $65,000-$70,000. Yet only the two expensive drugs were included in the PBM formulary. As a result, the cheapest drug holds only a sliver of market share; the remainder is dominated by the two expensive products, she told the House Oversight and Accountability Committee in 2021.

This Q&A has been edited for length and clarity.

What would you want federal and state policymakers to do in response to the FTC’s report?

I think Congress needs to clearly delineate the differences between anticompetitive pharmacy issues, drug pricing issues, and their effect on formulary construction issues.

Lawmakers should demand more transparency and consider legislation that would remove perverse incentives that prompt PBMs to choose higher priced drugs for their formularies. 

That may require other regulatory or legislative actions to ensure lower prices (not higher kickbacks) are incentivized. Ultimately, in order to gain true competition within the health insurance business, these oligopolies of multiple businesses need to be broken up. Anything less seems to be nibbling around the edges and allows the Big Three to continue their “whack-a mole” in circumventing piecemeal regulatory and legislative policies.

You’ve followed PBM practices closely for many years. Was there anything in this interim FTC report that surprised you?

Though not surprised, I am glad that it was released because it had been a year in investigation and there were many requests for some type of substantive report. 

Two things that are missing that I feel are paramount are investigating how the three big PBMs are causing physical harm to patients as a result of the profit component in formulary construction and the profound financial impact of hidden PBM profit centers in self-insured employer health plans.

What we have seen over the years is the result of the perverse incentives for the PBMs to prefer the most profitable medications on their formularies. 

They use utilization management tools such as step therapy, nonmedical switching, and exclusions to maintain their formularies’ profitability. These tools have been shown to delay and deny the proper care of patients, resulting in not just monetary but physical harm as well. 

I would think the physical harm done to patients in manipulating the formularies should be addressed in this report as well and, in fact, may be the most important aspect of consumer protection of this issue.

In terms of the FTC’s mission to not “unduly burden” legitimate business, I would like to see the sector of self-insured employers addressed.

Melasma (also known as chloasma faciei) is a common chronic skin disorder that results in well-demarcated, hyperpigmented, tan to dark patches that mostly appear in sun-exposed areas such as the face and neck and sometimes the arms. The exact prevalence or incidence is not known but is estimated to be 1% to 50% overall depending on the ethnic population and geographic location.^1,2 Melasma predominantly affects women, but research has shown that approximately 10% to 20% of men are affected by this condition.^3,4 Although melasma can affect patients of all skin types, it primarily affects those with darker skin tones.⁵ The groups most often affected are women of Black, Hispanic, Middle Eastern, and Southeast Asian ethnicity. Although the pathogenesis is complex and not fully understood, multiple pathways and etiologies have been theorized to cause melasma. Potential causes include exposure to UV radiation, oral contraceptives, hormonal changes, medications, thyroid dysfunction, genetics, and pregnancy.^6,7 Cytokines and growth factors, including adipokine and angiopoietin, synthesized by sebaceous glands play a role in the pathogenic mechanism of melasma. Cytokines and growth factors are hypothesized to modulate the function of melanocytes.⁸ Both melanocytes and sebocytes are controlled by α–melanocyte-stimulating hormone. Therefore, overexpression of α–melanocyte-stimulating hormone will result in overproduction of these 2 cell types, resulting in melasma. Melasma can be classified into 4 subtypes using Wood lamp examination: epidermal, dermal, mixed, or indeterminate.³ Furthermore, melasma is divided into subgroups based on the location: malar region, mandibular region, and centrofacial patch pattern.^9,10 The involvement of sebaceous glands in the pathogenesis of melasma may explain the predilection for the centrofacial region, which is the most common pattern.

The severity of melasma can be assessed using the melasma area and severity index (MASI), which is calculated by subjective assessment of 3 main factors: (1) facial area of involvement; (2) darkness of affected region; and (3) homogeneity, with the extent of melasma indicated by a score ranging from 0 to 48.¹¹ The modified MASI (mMASI) subsequently was introduced to assist with assessing the severity of melasma and creating distinct ranges for mild, moderate, and severe cases, ranging from 0 (mild) to 24 (severe).¹² Both indices are used in research to assess the improvement of melasma with treatment.

Patients with melasma report a decrease in quality of life, increased emotional stress, and lower self-esteem due to cosmesis.¹³ Treatment of melasma can be highly challenging and often is complicated by relapsing. Historically, the treatment of melasma has included the use of chemical lightening agents. Additional treatment options include the use of lasers and complex chemical peels,^9,10 but these interventions may result in adverse outcomes for individuals with darker skin tones. The current gold-standard treatment is topical hydroquinone and broad-spectrum sunscreen. Although hydroquinone is effective in the treatment of melasma, relapse is common. The goal of melasma management is not only to treat acute hyperpigmentation but also to prevent relapse. Other therapies that currently are being explored for the clinically sustained treatment of melasma include tranexamic acid (TXA)(trans-4-[aminomethyl]cyclohexanecarboxylic acid),^9,10 an antifibrinolytic agent routinely used to prevent blood loss during surgery and in the management of menorrhagia. It is a synthetic derivative of lysine and serves as a potent plasmin inhibitor by blocking the lysine-binding sites of plasminogen molecules, thus preventing the conversion of plasminogen to plasmin. It also prevents fibrinolysis and blood loss.

In addition to its hemostatic properties, TXA has been found to have hypopigmentation properties.^14,15 Plasminogen also can be found in human epidermal basal cells and human keratinocytes, and it is postulated that TXA’s interaction with these cells explains its hypopigmentation properties. Both UV radiation and hormones activate plasminogen into plasmin, resulting in the activation of tyrosinase and melanogenesis.^14,15 Tranexamic acid is postulated to inhibit the keratinocyte-plasminogen pathway, thus leading to the inhibition of UV-induced and hormone-induced pigmentation. Also, TXA serves as a competitive inhibitor for tyrosinase due to its structural similarity to tyrosine.¹⁵ The combination of these 2 mechanisms contributes to the skin-lightening effects of TXA, making it a potential treatment for melasma.

Furthermore, the use of microneedling is being explored as a treatment option for melasma. Microneedling creates microscopic punctures in the skin using tiny needles, resulting in a wound-healing response and skin resurfacing. The microneedling technique is utilized to create small holes in the skin, with needle depths that can be adjusted from 0.5 to 3.5 mm to target different layers of the dermis and allow for discreet application of TXA.¹⁶ We sought to look at the current literature on the use and effectiveness of microneedling in combination with TXA to treat melasma and prevent relapse.

Methods

A systematic review was performed of PubMed articles indexed for MEDLINE and Embase in November 2021 to compile available articles that studied TXA and microneedling as a treatment for melasma. The PubMed search terms were (melasma) AND (microneedling* OR ‘tranexamic acid’ OR TXA or TA). The Embase search terms were (cholasma OR melasma) AND (tranexamic acid OR TXA) AND (microneedling)(Figure). The search was then limited to ”randomized controlled trial” and ”clinical trial” in English-language journals. Duplicates were excluded. After thorough evaluation, articles that discussed the use of TXA in combination with treatment options other than microneedling also were excluded.

Results

The literature search yielded a total of 12 articles that assessed the effectiveness of TXA and microneedling for the treatment of melasma (Table).^17-28 Several articles concluded that TXA was equally effective at reducing melasma lesions when compared with the standard treatment of hydroquinone. Some of the reviewed articles also demonstrated the effectiveness of microneedling in improving melasma lesions as a stand-alone treatment. These studies highlighted the enhanced efficacy of the combined treatment of TXA and microneedling compared with their individual uses.^17-28

Comment

Melasma is a common chronic hyperpigmentation disorder, making its treatment clinically challenging. Many patients experience symptom relapses, and limited effective treatment options make achieving complete clearance difficult, underscoring the need for improved therapeutic approaches. Recently, researchers have explored alternative treatments to address the challenges of melasma management. Tranexamic acid is an antifibrinolytic used to prevent blood loss and has emerged as a potential treatment for melasma. Similarly, microneedling—a technique in which multiple punctures are made in the skin to activate and stimulate wound healing and skin rejuvenation—shows promise for melasma.

Oral TXA for Melasma—Oral TXA has been shown to reduce melasma lesions. Del Rosario et al¹⁷ recruited 44 women (39 of whom completed the study) with moderate to severe melasma and randomized them into 2 groups: oral TXA and placebo. This study demonstrated a 49% reduction in the mMASI score in all participants taking oral TXA (250 mg twice daily [BID]) compared with an 18% reduction in the control group (placebo capsule BID) after 3 months of treatment. In patients with moderate and severe melasma, 45% and 51% mMASI score reductions were reported in the treatment group, respectively, vs 16% and 19% score reductions in placebo group, respectively. These researchers concluded that oral TXA may be effective at treating moderate to severe melasma. Although patients with severe melasma had a better response to treatment, their improvement was not sustained compared with patients with moderate melasma after a 3-month posttreatment follow-up.¹⁷

Microneedling Plus TXA for Melasma—Microneedling alone has been shown to be effective for melasma. El Attar et al¹⁸ conducted a split-face study of microneedling (1.5-mm depth) plus topical TXA (0.5 mL)(right side of the face[treatment arm]) compared with microneedling (1.5-mm depth) plus topical vitamin C (0.5 mL)(left side of the face [control group]) in 20 women with melasma. The sessions were repeated every 2 weeks for a total of 6 sessions. Although researchers found no statistically significant differences between the 2 treatment sides, microneedling plus TXA showed a slight advantage over microneedling plus vitamin C in dermoscopic examination. Both sides showed improvement in pigmented lesions, but vitamin C–treated lesions did not show an improvement in vascularity vs TXA.¹⁸

Saleh et al¹⁹ further showed that combination treatment with microneedling and TXA may improve clinical outcomes better than microneedling alone. Their study demonstrated a reduction in MASI score that was significantly higher in the combination treatment group compared with the microneedling alone group (P=.001). There was a significant reduction in melanoma antigen recognized by T cells 1 (MART-1)–positive cells in the combination treatment group compared with the microneedling alone group (P=.001). Lastly, combined therapy improved melasma patches better than microneedling alone.¹⁹

Xu et al²⁰ conducted a split-face study (N=28) exploring the effectiveness of transdermal application of topical TXA using a microarray pen with microneedles (vibration at 3000×/min) plus topical TXA on one side of the face, while the other side received only topical TXA as a control. After 12 weeks of treatment, combination therapy with microneedling and TXA decreased brown spot scores, lowered melanin index (MI) values, improved blinded physician assessment, and improved patient satisfaction vs TXA therapy alone.²⁰

Kaur et al²¹ conducted a split-face, randomized, controlled trial of microneedling (1-mm depth) with TXA solution 10% vs microneedling (1-mm depth) with distilled water alone for 8 weeks (N=40). They graded participant responses to treatment using reductions in mMASI scores¹² at every 2 weeks of follow-up (no response, minimal or poor response=0%–25%; partial or fair response=26%–50%; good response=51%–75%; and excellent response=>75%). They reported an overall reduction in mMASI scores for both the treatment side and the control side in all participants, showing a 65.92% improvement in mean mMASI scores on the treatment side vs 20.75% improvement on the control side at week 8. Both sides showed statistically significant reductions in mean mMASI scores (P<.05). Clinically, 40% (16/40) of participants showed an excellent response to combined treatment compared with 0% (0/40) to microneedling alone. Overall, patient satisfaction was similar across both groups. This study demonstrated that microneedling alone improves melasma, but a combination of microneedling plus TXA showed a better clinical reduction in melasma. However, the researchers did not follow up with participants posttreatment, so it remains unclear if the improved clinical outcomes were sustained long-term.²¹

Ebrahim et al²² reported that the combination of 0.5 mL TXA (4 mg/mL) and microneedling (0.25- to 1-mm depth) was effective for melasma. Although there was improvement within microneedling and TXA, the study also showed that intradermal injection of TXA was significant in reducing mean mMASI scores and improving melasma (P<.001). The reduction in mMASI scores for the group receiving intradermal injections of TXA (left side; 74.8% reduction in mean mMASI score) vs the group receiving microneedling application of TXA (right side; 73.6% reduction in mean mMASI score) was not statistically significant. These findings suggest that the mode of TXA application may not be critical in determining clinical responses to TXA treatment. Although there was no reported statistically significant difference in clinical outcomes between the 2 treatments, patient satisfaction was higher on the microneedling side. Only 8 of 50 participants (16%) experienced recurrence 3 months posttreatment.²²

Saki et al²³ compared the efficacy of topical hydroquinone (2%) to intradermal TXA injections in treating melasma. They found intradermal TXA injections to be a clinically effective mode of treatment.²³

Sharma et al²⁴ explored the efficacy and safety of oral TXA by randomly assigning 100 Indian patients (20 of whom withdrew before study completion) with melasma into 2 groups: group A received TXA 250 mg twice daily, and group B received intradermal microinjections of TXA (4 mg/mL) every 4 weeks. The MASI scores were assessed at 4-week intervals for a total of 12 weeks. There was a decrease in MASI scores in both groups, and there was no statistically significant difference in mean percentage reduction in MASI scores between the 2 routes of drug administration, further suggesting the effectiveness of TXA independent of administration route. Two patients in group A relapsed at 24 weeks, and there were no relapses in group B, which may suggest a minimal superiority of TXA plus microneedling at providing more sustainable results compared with oral TXA alone. A notable limitation of this study was a high dropout rate as well as lack of long-term follow-up with participants, limiting the generalizability of the conclusions.²⁴

Cassiano et al²⁵ assigned 64 women with melasma to 1 of 3 treatment groups or a control group to compare the effectiveness of microneedling (M group: 1.5 mm; 2 sessions), oral TXA (T group: 250 mg/d twice daily for 60 days), and a combination of microneedling (2 sessions) and oral TXA (MT group: 250 mg/d twice daily for 60 days)with placebo for clinically reducing melasma lesions. The intervention period was 60 days followed by a 60-day maintenance phase for a total study period of 120 days. The researchers evaluated mMASI scores, quality of life, and difference in colorimetric luminosity. All treatment groups showed a reduction in mMASI scores at both 30 days and 60 days, indicating improved melasma severity. The MT and T groups had more significant improvement at 30 days compared with the control group (P<.03), suggesting that microneedling plus TXA and TXA alone promote faster improvement in melasma lesions. By 60 days, the M, T, and MT groups outperformed the control group, with no significant differences between the M, T, and MT groups. However, at the 120-day maintenance follow-up, the T group did not maintain its improvement compared with the control group. The M and MT groups showed no significance difference in effectiveness at 120 days, suggesting that microneedling may promote less frequent relapse and sustained remission compared to TXA alone.²⁵

Hydroquinone for Melasma—Additional studies on the use of TXA treatments show that TXA may be an equally effective alternative to the standard use of hydroquinone treatment. Shamsi Meymandi et al²⁶ did not find a statistically significant difference in treatment with TXA plus microneedling vs the standard regimen of hydroquinone. More importantly, patient and physician satisfaction assessments were similar between the 2 groups. Compared to hydroquinone, nightly treatment is not necessary with microneedling and TXA.²⁶

Xing et al²⁷ supported these conclusions with their study. They compared 3 study arms for a duration of 12 weeks: group A received topical 1.8% liposomal TXA BID, group B received stamp-mode electric microneedling with 5% TXA weekly, and group C applied 2% ­hydroquinone cream nightly. The study concluded that all 3 groups showed a significant reduction in mean MI by the end of the study, but a better MI improvement was observed in groups B and C (both P<.001) compared with group A (P<.01).²⁷

Zaky et al²⁸ showed that both hydroquinone and combination treatment of TXA plus microneedling are effective at improving melasma lesions. Further studies are needed to definitively conclude if combination treatment is more efficacious than hydroquinone; if the combination is more effective, it provides a treatment option for patients with melasma who may not be good candidates for hydroquinone treatment.

Study Limitations—One limitation in all the studies evaluated is the sample size. Because they all had small sample sizes, it is difficult to definitively conclude that the combination TXA and microneedling is an effective and appropriate treatment for patients with melasma. Furthermore, the quality of these studies was mostly dependent on subjectivity of the mMASI scores. Future large randomized controlled trials with a diverse participant population are needed to assess the effectiveness of TXA and microneedling in melasma treatment.

Another limitation is that many of the studies did not follow the patients longitudinally, which did not allow for an evaluation of whether patients had a relapse of melasma. Due to the chronic nature of melasma and frequent disease recurrence, future longitudinal studies are needed to monitor for disease recurrence.

Conclusion

Tranexamic acid and microneedling are potential treatment options for patients with melasma, and combination therapy appears more effective than either TXA or microneedling alone at providing sustained improvement of melasma lesions. Combination therapy appears safe and well tolerated, but its effect on reducing long-term disease recurrence is yet to be established.

Xu et al²⁰ conducted a split-face study (N=28) exploring the effectiveness of transdermal application of topical TXA using a microarray pen with microneedles (vibration at 3000×/min) plus topical TXA on one side of the face, while the other side received only topical TXA as a control. After 12 weeks of treatment, combination therapy with microneedling and TXA decreased brown spot scores, lowered melanin index (MI) values, improved blinded physician assessment, and improved patient satisfaction vs TXA therapy alone.²⁰

Kaur et al²¹ conducted a split-face, randomized, controlled trial of microneedling (1-mm depth) with TXA solution 10% vs microneedling (1-mm depth) with distilled water alone for 8 weeks (N=40). They graded participant responses to treatment using reductions in mMASI scores¹² at every 2 weeks of follow-up (no response, minimal or poor response=0%–25%; partial or fair response=26%–50%; good response=51%–75%; and excellent response=>75%). They reported an overall reduction in mMASI scores for both the treatment side and the control side in all participants, showing a 65.92% improvement in mean mMASI scores on the treatment side vs 20.75% improvement on the control side at week 8. Both sides showed statistically significant reductions in mean mMASI scores (P<.05). Clinically, 40% (16/40) of participants showed an excellent response to combined treatment compared with 0% (0/40) to microneedling alone. Overall, patient satisfaction was similar across both groups. This study demonstrated that microneedling alone improves melasma, but a combination of microneedling plus TXA showed a better clinical reduction in melasma. However, the researchers did not follow up with participants posttreatment, so it remains unclear if the improved clinical outcomes were sustained long-term.²¹

Ebrahim et al²² reported that the combination of 0.5 mL TXA (4 mg/mL) and microneedling (0.25- to 1-mm depth) was effective for melasma. Although there was improvement within microneedling and TXA, the study also showed that intradermal injection of TXA was significant in reducing mean mMASI scores and improving melasma (P<.001). The reduction in mMASI scores for the group receiving intradermal injections of TXA (left side; 74.8% reduction in mean mMASI score) vs the group receiving microneedling application of TXA (right side; 73.6% reduction in mean mMASI score) was not statistically significant. These findings suggest that the mode of TXA application may not be critical in determining clinical responses to TXA treatment. Although there was no reported statistically significant difference in clinical outcomes between the 2 treatments, patient satisfaction was higher on the microneedling side. Only 8 of 50 participants (16%) experienced recurrence 3 months posttreatment.²²

Saki et al²³ compared the efficacy of topical hydroquinone (2%) to intradermal TXA injections in treating melasma. They found intradermal TXA injections to be a clinically effective mode of treatment.²³

Sharma et al²⁴ explored the efficacy and safety of oral TXA by randomly assigning 100 Indian patients (20 of whom withdrew before study completion) with melasma into 2 groups: group A received TXA 250 mg twice daily, and group B received intradermal microinjections of TXA (4 mg/mL) every 4 weeks. The MASI scores were assessed at 4-week intervals for a total of 12 weeks. There was a decrease in MASI scores in both groups, and there was no statistically significant difference in mean percentage reduction in MASI scores between the 2 routes of drug administration, further suggesting the effectiveness of TXA independent of administration route. Two patients in group A relapsed at 24 weeks, and there were no relapses in group B, which may suggest a minimal superiority of TXA plus microneedling at providing more sustainable results compared with oral TXA alone. A notable limitation of this study was a high dropout rate as well as lack of long-term follow-up with participants, limiting the generalizability of the conclusions.²⁴

Cassiano et al²⁵ assigned 64 women with melasma to 1 of 3 treatment groups or a control group to compare the effectiveness of microneedling (M group: 1.5 mm; 2 sessions), oral TXA (T group: 250 mg/d twice daily for 60 days), and a combination of microneedling (2 sessions) and oral TXA (MT group: 250 mg/d twice daily for 60 days)with placebo for clinically reducing melasma lesions. The intervention period was 60 days followed by a 60-day maintenance phase for a total study period of 120 days. The researchers evaluated mMASI scores, quality of life, and difference in colorimetric luminosity. All treatment groups showed a reduction in mMASI scores at both 30 days and 60 days, indicating improved melasma severity. The MT and T groups had more significant improvement at 30 days compared with the control group (P<.03), suggesting that microneedling plus TXA and TXA alone promote faster improvement in melasma lesions. By 60 days, the M, T, and MT groups outperformed the control group, with no significant differences between the M, T, and MT groups. However, at the 120-day maintenance follow-up, the T group did not maintain its improvement compared with the control group. The M and MT groups showed no significance difference in effectiveness at 120 days, suggesting that microneedling may promote less frequent relapse and sustained remission compared to TXA alone.²⁵

Hydroquinone for Melasma—Additional studies on the use of TXA treatments show that TXA may be an equally effective alternative to the standard use of hydroquinone treatment. Shamsi Meymandi et al²⁶ did not find a statistically significant difference in treatment with TXA plus microneedling vs the standard regimen of hydroquinone. More importantly, patient and physician satisfaction assessments were similar between the 2 groups. Compared to hydroquinone, nightly treatment is not necessary with microneedling and TXA.²⁶

Xing et al²⁷ supported these conclusions with their study. They compared 3 study arms for a duration of 12 weeks: group A received topical 1.8% liposomal TXA BID, group B received stamp-mode electric microneedling with 5% TXA weekly, and group C applied 2% ­hydroquinone cream nightly. The study concluded that all 3 groups showed a significant reduction in mean MI by the end of the study, but a better MI improvement was observed in groups B and C (both P<.001) compared with group A (P<.01).²⁷

Zaky et al²⁸ showed that both hydroquinone and combination treatment of TXA plus microneedling are effective at improving melasma lesions. Further studies are needed to definitively conclude if combination treatment is more efficacious than hydroquinone; if the combination is more effective, it provides a treatment option for patients with melasma who may not be good candidates for hydroquinone treatment.

Study Limitations—One limitation in all the studies evaluated is the sample size. Because they all had small sample sizes, it is difficult to definitively conclude that the combination TXA and microneedling is an effective and appropriate treatment for patients with melasma. Furthermore, the quality of these studies was mostly dependent on subjectivity of the mMASI scores. Future large randomized controlled trials with a diverse participant population are needed to assess the effectiveness of TXA and microneedling in melasma treatment.

Another limitation is that many of the studies did not follow the patients longitudinally, which did not allow for an evaluation of whether patients had a relapse of melasma. Due to the chronic nature of melasma and frequent disease recurrence, future longitudinal studies are needed to monitor for disease recurrence.

Conclusion

Tranexamic acid and microneedling are potential treatment options for patients with melasma, and combination therapy appears more effective than either TXA or microneedling alone at providing sustained improvement of melasma lesions. Combination therapy appears safe and well tolerated, but its effect on reducing long-term disease recurrence is yet to be established.

Melasma (also known as chloasma faciei) is a common chronic skin disorder that results in well-demarcated, hyperpigmented, tan to dark patches that mostly appear in sun-exposed areas such as the face and neck and sometimes the arms. The exact prevalence or incidence is not known but is estimated to be 1% to 50% overall depending on the ethnic population and geographic location.^1,2 Melasma predominantly affects women, but research has shown that approximately 10% to 20% of men are affected by this condition.^3,4 Although melasma can affect patients of all skin types, it primarily affects those with darker skin tones.⁵ The groups most often affected are women of Black, Hispanic, Middle Eastern, and Southeast Asian ethnicity. Although the pathogenesis is complex and not fully understood, multiple pathways and etiologies have been theorized to cause melasma. Potential causes include exposure to UV radiation, oral contraceptives, hormonal changes, medications, thyroid dysfunction, genetics, and pregnancy.^6,7 Cytokines and growth factors, including adipokine and angiopoietin, synthesized by sebaceous glands play a role in the pathogenic mechanism of melasma. Cytokines and growth factors are hypothesized to modulate the function of melanocytes.⁸ Both melanocytes and sebocytes are controlled by α–melanocyte-stimulating hormone. Therefore, overexpression of α–melanocyte-stimulating hormone will result in overproduction of these 2 cell types, resulting in melasma. Melasma can be classified into 4 subtypes using Wood lamp examination: epidermal, dermal, mixed, or indeterminate.³ Furthermore, melasma is divided into subgroups based on the location: malar region, mandibular region, and centrofacial patch pattern.^9,10 The involvement of sebaceous glands in the pathogenesis of melasma may explain the predilection for the centrofacial region, which is the most common pattern.

The severity of melasma can be assessed using the melasma area and severity index (MASI), which is calculated by subjective assessment of 3 main factors: (1) facial area of involvement; (2) darkness of affected region; and (3) homogeneity, with the extent of melasma indicated by a score ranging from 0 to 48.¹¹ The modified MASI (mMASI) subsequently was introduced to assist with assessing the severity of melasma and creating distinct ranges for mild, moderate, and severe cases, ranging from 0 (mild) to 24 (severe).¹² Both indices are used in research to assess the improvement of melasma with treatment.

Patients with melasma report a decrease in quality of life, increased emotional stress, and lower self-esteem due to cosmesis.¹³ Treatment of melasma can be highly challenging and often is complicated by relapsing. Historically, the treatment of melasma has included the use of chemical lightening agents. Additional treatment options include the use of lasers and complex chemical peels,^9,10 but these interventions may result in adverse outcomes for individuals with darker skin tones. The current gold-standard treatment is topical hydroquinone and broad-spectrum sunscreen. Although hydroquinone is effective in the treatment of melasma, relapse is common. The goal of melasma management is not only to treat acute hyperpigmentation but also to prevent relapse. Other therapies that currently are being explored for the clinically sustained treatment of melasma include tranexamic acid (TXA)(trans-4-[aminomethyl]cyclohexanecarboxylic acid),^9,10 an antifibrinolytic agent routinely used to prevent blood loss during surgery and in the management of menorrhagia. It is a synthetic derivative of lysine and serves as a potent plasmin inhibitor by blocking the lysine-binding sites of plasminogen molecules, thus preventing the conversion of plasminogen to plasmin. It also prevents fibrinolysis and blood loss.

In addition to its hemostatic properties, TXA has been found to have hypopigmentation properties.^14,15 Plasminogen also can be found in human epidermal basal cells and human keratinocytes, and it is postulated that TXA’s interaction with these cells explains its hypopigmentation properties. Both UV radiation and hormones activate plasminogen into plasmin, resulting in the activation of tyrosinase and melanogenesis.^14,15 Tranexamic acid is postulated to inhibit the keratinocyte-plasminogen pathway, thus leading to the inhibition of UV-induced and hormone-induced pigmentation. Also, TXA serves as a competitive inhibitor for tyrosinase due to its structural similarity to tyrosine.¹⁵ The combination of these 2 mechanisms contributes to the skin-lightening effects of TXA, making it a potential treatment for melasma.

Furthermore, the use of microneedling is being explored as a treatment option for melasma. Microneedling creates microscopic punctures in the skin using tiny needles, resulting in a wound-healing response and skin resurfacing. The microneedling technique is utilized to create small holes in the skin, with needle depths that can be adjusted from 0.5 to 3.5 mm to target different layers of the dermis and allow for discreet application of TXA.¹⁶ We sought to look at the current literature on the use and effectiveness of microneedling in combination with TXA to treat melasma and prevent relapse.

Methods

A systematic review was performed of PubMed articles indexed for MEDLINE and Embase in November 2021 to compile available articles that studied TXA and microneedling as a treatment for melasma. The PubMed search terms were (melasma) AND (microneedling* OR ‘tranexamic acid’ OR TXA or TA). The Embase search terms were (cholasma OR melasma) AND (tranexamic acid OR TXA) AND (microneedling)(Figure). The search was then limited to ”randomized controlled trial” and ”clinical trial” in English-language journals. Duplicates were excluded. After thorough evaluation, articles that discussed the use of TXA in combination with treatment options other than microneedling also were excluded.

Results

The literature search yielded a total of 12 articles that assessed the effectiveness of TXA and microneedling for the treatment of melasma (Table).^17-28 Several articles concluded that TXA was equally effective at reducing melasma lesions when compared with the standard treatment of hydroquinone. Some of the reviewed articles also demonstrated the effectiveness of microneedling in improving melasma lesions as a stand-alone treatment. These studies highlighted the enhanced efficacy of the combined treatment of TXA and microneedling compared with their individual uses.^17-28

Comment

Melasma is a common chronic hyperpigmentation disorder, making its treatment clinically challenging. Many patients experience symptom relapses, and limited effective treatment options make achieving complete clearance difficult, underscoring the need for improved therapeutic approaches. Recently, researchers have explored alternative treatments to address the challenges of melasma management. Tranexamic acid is an antifibrinolytic used to prevent blood loss and has emerged as a potential treatment for melasma. Similarly, microneedling—a technique in which multiple punctures are made in the skin to activate and stimulate wound healing and skin rejuvenation—shows promise for melasma.

Oral TXA for Melasma—Oral TXA has been shown to reduce melasma lesions. Del Rosario et al¹⁷ recruited 44 women (39 of whom completed the study) with moderate to severe melasma and randomized them into 2 groups: oral TXA and placebo. This study demonstrated a 49% reduction in the mMASI score in all participants taking oral TXA (250 mg twice daily [BID]) compared with an 18% reduction in the control group (placebo capsule BID) after 3 months of treatment. In patients with moderate and severe melasma, 45% and 51% mMASI score reductions were reported in the treatment group, respectively, vs 16% and 19% score reductions in placebo group, respectively. These researchers concluded that oral TXA may be effective at treating moderate to severe melasma. Although patients with severe melasma had a better response to treatment, their improvement was not sustained compared with patients with moderate melasma after a 3-month posttreatment follow-up.¹⁷

Microneedling Plus TXA for Melasma—Microneedling alone has been shown to be effective for melasma. El Attar et al¹⁸ conducted a split-face study of microneedling (1.5-mm depth) plus topical TXA (0.5 mL)(right side of the face[treatment arm]) compared with microneedling (1.5-mm depth) plus topical vitamin C (0.5 mL)(left side of the face [control group]) in 20 women with melasma. The sessions were repeated every 2 weeks for a total of 6 sessions. Although researchers found no statistically significant differences between the 2 treatment sides, microneedling plus TXA showed a slight advantage over microneedling plus vitamin C in dermoscopic examination. Both sides showed improvement in pigmented lesions, but vitamin C–treated lesions did not show an improvement in vascularity vs TXA.¹⁸

Saleh et al¹⁹ further showed that combination treatment with microneedling and TXA may improve clinical outcomes better than microneedling alone. Their study demonstrated a reduction in MASI score that was significantly higher in the combination treatment group compared with the microneedling alone group (P=.001). There was a significant reduction in melanoma antigen recognized by T cells 1 (MART-1)–positive cells in the combination treatment group compared with the microneedling alone group (P=.001). Lastly, combined therapy improved melasma patches better than microneedling alone.¹⁹

What if a drug could help you live a longer, healthier life?

Scientists at the University of Connecticut are working on it. In a new study in Cell Metabolism, researchers described how to target specific cells to extend the lifespan and improve the health of mice late in life.

The study builds on a growing body of research, mostly in animals, testing interventions to slow aging and prolong health span, the length of time that one is not just alive but also healthy.

“Aging is the most important risk factor for every disease that we deal with in adult human beings,” said cardiologist Douglas Vaughan, MD, director of the Potocsnak Longevity Institute at Northwestern University’s Feinberg School of Medicine, Chicago. (Dr. Vaughan was not involved in the new study.) “So the big hypothesis is: If we could slow down aging just a little bit, we can push back the onset of disease.”

As we age, our cells wear out. It’s called cellular senescence — a state of irreversible cell cycle arrest — and it’s increasingly recognized as a key contributor to aging.

Senescent cells — or “zombie cells” — secrete harmful substances that disrupt tissue functioning. They’ve been linked to chronic inflammation, tissue damage, and the development of age-related diseases.

Senescence can be characterized by the accumulation of cells with high levels of specific markers like p21, or p21^high cells. Almost any cell can become a p21^high cell, and they accumulate with age, said Ming Xu, PhD, a professor at the UConn Center on Aging, UConn Health, Farmington, Connecticut, who led the study.

By targeting and eliminating p21^high senescent cells, Dr. Xu hopes to develop novel therapies that might help people live longer and enjoy more years in good health.

Such a treatment could be ready for human trials in 2-5 years, Dr. Xu said.
 

What the Researchers Did

Xu and colleagues used genetic engineering to eliminate p21^high cells in mice, introducing into their genome something they describe as an inducible “suicide gene.” Giving the mice a certain drug (a low dose of tamoxifen) activated the suicide gene in all p21^high cells, causing them to die. Administering this treatment once a month, from age 20 months (older age) until the end of life, significantly extended the rodents’ lifespan, reduced inflammation, and decreased gene activity linked to aging.

Treated mice lived, on average, for 33 months — 3 months longer than the untreated mice. The oldest treated mouse lived to 43 months — roughly 130 in human years.

But the treated mice didn’t just live longer; they were also healthier. In humans, walking speed and grip strength can be clues of overall health and vitality. The old, treated mice were able to walk faster and grip objects with greater strength than untreated mice of the same age.

Dr. Xu’s lab is now testing drugs that target p21^high cells in hopes of finding one that would work in humans. Leveraging immunotherapy technology to target these cells could be another option, Dr. Xu said.

The team also plans to test whether eliminating p21^high cells could prevent or alleviate diabetes or Alzheimer’s disease.
 

Challenges and Criticisms

The research provides “important evidence that targeting senescence and the molecular components of that pathway might provide some benefit in the long term,” Dr. Vaughan said.

But killing senescent cells could come with downsides.

“Senescence protects us from hyperproliferative responses,” potentially blocking cells from becoming malignant, Dr. Vaughan said. “There’s this effect on aging that is desirable, but at the same time, you may enhance your risk of cancer or malignancy or excessive proliferation in some cells.”

And of course, we don’t necessarily need drugs to prolong healthy life, Dr. Vaughan pointed out.

For many people, a long healthy life is already within reach. Humans live longer on average than they used to, and simple lifestyle choices — nourishing your body well, staying active, and maintaining a healthy weight — can increase one’s chances of good health.

The most consistently demonstrated intervention for extending lifespan “in almost every animal species is caloric restriction,” Dr. Vaughan said. (Dr. Xu’s team is also investigating whether fasting and exercise can lead to a decrease in p21^high cells.)

As for brain health, Dr. Vaughan and colleagues at Northwestern are studying “super agers,” people who are cognitively intact into their 90s.

“The one single thing that they found that contributes to that process, and contributes to that success, is really a social network and human bonds and interaction,” Dr. Vaughan said.

Scientists at the University of Connecticut are working on it. In a new study in Cell Metabolism, researchers described how to target specific cells to extend the lifespan and improve the health of mice late in life.

The study builds on a growing body of research, mostly in animals, testing interventions to slow aging and prolong health span, the length of time that one is not just alive but also healthy.

“Aging is the most important risk factor for every disease that we deal with in adult human beings,” said cardiologist Douglas Vaughan, MD, director of the Potocsnak Longevity Institute at Northwestern University’s Feinberg School of Medicine, Chicago. (Dr. Vaughan was not involved in the new study.) “So the big hypothesis is: If we could slow down aging just a little bit, we can push back the onset of disease.”

As we age, our cells wear out. It’s called cellular senescence — a state of irreversible cell cycle arrest — and it’s increasingly recognized as a key contributor to aging.

Senescent cells — or “zombie cells” — secrete harmful substances that disrupt tissue functioning. They’ve been linked to chronic inflammation, tissue damage, and the development of age-related diseases.

Senescence can be characterized by the accumulation of cells with high levels of specific markers like p21, or p21^high cells. Almost any cell can become a p21^high cell, and they accumulate with age, said Ming Xu, PhD, a professor at the UConn Center on Aging, UConn Health, Farmington, Connecticut, who led the study.

By targeting and eliminating p21^high senescent cells, Dr. Xu hopes to develop novel therapies that might help people live longer and enjoy more years in good health.

Such a treatment could be ready for human trials in 2-5 years, Dr. Xu said.
 

What the Researchers Did

Xu and colleagues used genetic engineering to eliminate p21^high cells in mice, introducing into their genome something they describe as an inducible “suicide gene.” Giving the mice a certain drug (a low dose of tamoxifen) activated the suicide gene in all p21^high cells, causing them to die. Administering this treatment once a month, from age 20 months (older age) until the end of life, significantly extended the rodents’ lifespan, reduced inflammation, and decreased gene activity linked to aging.

Treated mice lived, on average, for 33 months — 3 months longer than the untreated mice. The oldest treated mouse lived to 43 months — roughly 130 in human years.

But the treated mice didn’t just live longer; they were also healthier. In humans, walking speed and grip strength can be clues of overall health and vitality. The old, treated mice were able to walk faster and grip objects with greater strength than untreated mice of the same age.

Dr. Xu’s lab is now testing drugs that target p21^high cells in hopes of finding one that would work in humans. Leveraging immunotherapy technology to target these cells could be another option, Dr. Xu said.

The team also plans to test whether eliminating p21^high cells could prevent or alleviate diabetes or Alzheimer’s disease.
 

Challenges and Criticisms

The research provides “important evidence that targeting senescence and the molecular components of that pathway might provide some benefit in the long term,” Dr. Vaughan said.

But killing senescent cells could come with downsides.

“Senescence protects us from hyperproliferative responses,” potentially blocking cells from becoming malignant, Dr. Vaughan said. “There’s this effect on aging that is desirable, but at the same time, you may enhance your risk of cancer or malignancy or excessive proliferation in some cells.”

And of course, we don’t necessarily need drugs to prolong healthy life, Dr. Vaughan pointed out.

For many people, a long healthy life is already within reach. Humans live longer on average than they used to, and simple lifestyle choices — nourishing your body well, staying active, and maintaining a healthy weight — can increase one’s chances of good health.

The most consistently demonstrated intervention for extending lifespan “in almost every animal species is caloric restriction,” Dr. Vaughan said. (Dr. Xu’s team is also investigating whether fasting and exercise can lead to a decrease in p21^high cells.)

As for brain health, Dr. Vaughan and colleagues at Northwestern are studying “super agers,” people who are cognitively intact into their 90s.

“The one single thing that they found that contributes to that process, and contributes to that success, is really a social network and human bonds and interaction,” Dr. Vaughan said.
