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?”

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.”

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.

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.

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.

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.

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.

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.

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.

The Heritage Foundation sponsored and developed Project 2025 for the explicit, stated purpose of building a conservative victory through policy, personnel, and training with a 180-day game plan after a sympathetic new President of the United States takes office. To date, Project 2025 has not been formally endorsed by any presidential campaign.

More than 100 conservative organizations are said to be participating. More than 400 conservative scholars and experts have collaborated in authorship of the mandate’s 40 chapters. Chapter 14 of the “Mandate for Leadership” is an exhaustive proposed overhaul of the Department of Health and Human Services (HHS), one of the major existing arms of the executive branch of the US government. 

The mandate’s sweeping recommendations, if implemented, would impact the lives of all Americans and all healthcare workers, as outlined in the following excerpts. 
 

Healthcare-Related Excerpts From Project 2025

• “From the moment of conception, every human being possesses inherent dignity and worth, and our humanity does not depend on our age, stage of development, race, or abilities. The Secretary must ensure that all HHS programs and activities are rooted in a deep respect for innocent human life from day one until natural death: Abortion and euthanasia are not health care.”
• “Unfortunately, family policies and programs under President Biden’s HHS are fraught with agenda items focusing on ‘LGBTQ+ equity,’ subsidizing single motherhood, disincentivizing work, and penalizing marriage. These policies should be repealed and replaced by policies that support the formation of stable, married, nuclear families.”
• “The next Administration should guard against the regulatory capture of our public health agencies by pharmaceutical companies, insurers, hospital conglomerates, and related economic interests that these agencies are meant to regulate. We must erect robust firewalls to mitigate these obvious financial conflicts of interest.”
• “All National Institutes of Health, Centers for Disease Control and Prevention, and Food and Drug Administration regulators should be entirely free from private biopharmaceutical funding. In this realm, ‘public–private partnerships’ is a euphemism for agency capture, a thin veneer for corporatism. Funding for agencies and individual government researchers must come directly from the government with robust congressional oversight.”
• “The CDC [Centers for Disease Control and Prevention] operates several programs related to vaccine safety including the Vaccine Adverse Event Reporting System (VAERS); Vaccine Safety Datalink (VSD); and Clinical Immunization Safety Assessment (CISA) Project. Those functions and their associated funding should be transferred to the FDA [Food and Drug Administration], which is responsible for post-market surveillance and evaluation of all other drugs and biological products.”
• “Because liberal states have now become sanctuaries for abortion tourism, HHS should use every available tool, including the cutting of funds, to ensure that every state reports exactly how many abortions take place within its borders, at what gestational age of the child, for what reason, the mother’s state of residence, and by what method. It should also ensure that statistics are separated by category: spontaneous miscarriage; treatments that incidentally result in the death of a child (such as chemotherapy); stillbirths; and induced abortion. In addition, CDC should require monitoring and reporting for complications due to abortion and every instance of children being born alive after an abortion.”
• “The CDC should immediately end its collection of data on gender identity, which legitimizes the unscientific notion that men can become women (and vice versa) and encourages the phenomenon of ever-multiplying subjective identities.”
• “A test developed by a lab in accordance with the protocols developed by another lab (non-commercial sharing) currently constitutes a ‘new’ laboratory-developed test because the lab in which it will be used is different from the initial developing lab. To encourage interlaboratory collaboration and discourage duplicative test creation (and associated regulatory and logistical burdens), the FDA should introduce mechanisms through which laboratory-developed tests can easily be shared with other laboratories without the current regulatory burdens.”
• “[FDA should] Reverse its approval of chemical abortion drugs because the politicized approval process was illegal from the start. The FDA failed to abide by its legal obligations to protect the health, safety, and welfare of girls and women.”
• “[FDA should] Stop promoting or approving mail-order abortions in violation of long-standing federal laws that prohibit the mailing and interstate carriage of abortion drugs.”
• “[HHS should] Promptly restore the ethics advisory committee to oversee abortion-derived fetal tissue research, and Congress should prohibit such research altogether.”
• “[HHS should] End intramural research projects using tissue from aborted children within the NIH, which should end its human embryonic stem cell registry.”
• “Under Francis Collins, NIH became so focused on the #MeToo movement that it refused to sponsor scientific conferences unless there were a certain number of women panelists, which violates federal civil rights law against sex discrimination. This quota practice should be ended, and the NIH Office of Equity, Diversity, and Inclusion, which pushes such unlawful actions, should be abolished.”
• “Make Medicare Advantage [MA] the default enrollment option.”
• “[Legislation reforming legacy (non-MA) Medicare should] Repeal harmful health policies enacted under the Obama and Biden Administrations such as the Medicare Shared Savings Program and Inflation Reduction Act.”
• “…the next Administration should] Add work requirements and match Medicaid benefits to beneficiary needs. Because Medicaid serves a broad and diverse group of individuals, it should be flexible enough to accommodate different designs for different groups.”
• “The No Surprises Act should scrap the dispute resolution process in favor of a truth-in-advertising approach that will protect consumers and free doctors, insurers, and arbiters from confused and conflicting standards for resolving disputes that the disputing parties can best resolve themselves.”
• “Prohibit abortion travel funding. Providing funding for abortions increases the number of abortions and violates the conscience and religious freedom rights of Americans who object to subsidizing the taking of life.”
• “Prohibit Planned Parenthood from receiving Medicaid funds. During the 2020–2021 reporting period, Planned Parenthood performed more than 383,000 abortions.”
• “Protect faith-based grant recipients from religious liberty violations and maintain a biblically based, social science–reinforced definition of marriage and family. Social science reports that assess the objective outcomes for children raised in homes aside from a heterosexual, intact marriage are clear.”
• “Allocate funding to strategy programs promoting father involvement or terminate parental rights quickly.”
• “Eliminate the Head Start program.”
• “Support palliative care. Physician-assisted suicide (PAS) is legal in 10 states and the District of Columbia. Legalizing PAS is a grave mistake that endangers the weak and vulnerable, corrupts the practice of medicine and the doctor–patient relationship, compromises the family and intergenerational commitments, and betrays human dignity and equality before the law.”
• “Eliminate men’s preventive services from the women’s preventive services mandate. In December 2021, HRSA [Health Resources and Services Administration] updated its women’s preventive services guidelines to include male condoms.”
• “Prioritize funding for home-based childcare, not universal day care.”
• “ The Office of the Secretary should eliminate the HHS Reproductive Healthcare Access Task Force and install a pro-life task force to ensure that all of the department’s divisions seek to use their authority to promote the life and health of women and their unborn children.”
• “The ASH [Assistant Secretary for Health] and SG [Surgeon General] positions should be combined into one four-star position with the rank, responsibilities, and authority of the ASH retained but with the title of Surgeon General.”
• “OCR [Office for Civil Rights] should withdraw its Health Insurance Portability and Accountability Act (HIPAA) guidance on abortion.”

The Secretary must ensure that all HHS programs and activities are rooted in a deep respect for innocent human life from day one until natural death: Abortion and euthanasia are not health care.”
• “Unfortunately, family policies and programs under President Biden’s HHS are fraught with agenda items focusing on ‘LGBTQ+ equity,’ subsidizing single motherhood, disincentivizing work, and penalizing marriage. These policies should be repealed and replaced by policies that support the formation of stable, married, nuclear families.”
• “The next Administration should guard against the regulatory capture of our public health agencies by pharmaceutical companies, insurers, hospital conglomerates, and related economic interests that these agencies are meant to regulate. We must erect robust firewalls to mitigate these obvious financial conflicts of interest.”
• “All National Institutes of Health, Centers for Disease Control and Prevention, and Food and Drug Administration regulators should be entirely free from private biopharmaceutical funding. In this realm, ‘public–private partnerships’ is a euphemism for agency capture, a thin veneer for corporatism. Funding for agencies and individual government researchers must come directly from the government with robust congressional oversight.”
• “The CDC [Centers for Disease Control and Prevention] operates several programs related to vaccine safety including the Vaccine Adverse Event Reporting System (VAERS); Vaccine Safety Datalink (VSD); and Clinical Immunization Safety Assessment (CISA) Project. Those functions and their associated funding should be transferred to the FDA [Food and Drug Administration], which is responsible for post-market surveillance and evaluation of all other drugs and biological products.”
• “Because liberal states have now become sanctuaries for abortion tourism, HHS should use every available tool, including the cutting of funds, to ensure that every state reports exactly how many abortions take place within its borders, at what gestational age of the child, for what reason, the mother’s state of residence, and by what method. It should also ensure that statistics are separated by category: spontaneous miscarriage; treatments that incidentally result in the death of a child (such as chemotherapy); stillbirths; and induced abortion. In addition, CDC should require monitoring and reporting for complications due to abortion and every instance of children being born alive after an abortion.”
• “The CDC should immediately end its collection of data on gender identity, which legitimizes the unscientific notion that men can become women (and vice versa) and encourages the phenomenon of ever-multiplying subjective identities.”
• “A test developed by a lab in accordance with the protocols developed by another lab (non-commercial sharing) currently constitutes a ‘new’ laboratory-developed test because the lab in which it will be used is different from the initial developing lab. To encourage interlaboratory collaboration and discourage duplicative test creation (and associated regulatory and logistical burdens), the FDA should introduce mechanisms through which laboratory-developed tests can easily be shared with other laboratories without the current regulatory burdens.”
• “[FDA should] Reverse its approval of chemical abortion drugs because the politicized approval process was illegal from the start. The FDA failed to abide by its legal obligations to protect the health, safety, and welfare of girls and women.”
• “[FDA should] Stop promoting or approving mail-order abortions in violation of long-standing federal laws that prohibit the mailing and interstate carriage of abortion drugs.”
• “[HHS should] Promptly restore the ethics advisory committee to oversee abortion-derived fetal tissue research, and Congress should prohibit such research altogether.”
• “[HHS should] End intramural research projects using tissue from aborted children within the NIH, which should end its human embryonic stem cell registry.”
• “Under Francis Collins, NIH became so focused on the #MeToo movement that it refused to sponsor scientific conferences unless there were a certain number of women panelists, which violates federal civil rights law against sex discrimination. This quota practice should be ended, and the NIH Office of Equity, Diversity, and Inclusion, which pushes such unlawful actions, should be abolished.”
• “Make Medicare Advantage [MA] the default enrollment option.”
• “[Legislation reforming legacy (non-MA) Medicare should] Repeal harmful health policies enacted under the Obama and Biden Administrations such as the Medicare Shared Savings Program and Inflation Reduction Act.”
• “…the next Administration should] Add work requirements and match Medicaid benefits to beneficiary needs. Because Medicaid serves a broad and diverse group of individuals, it should be flexible enough to accommodate different designs for different groups.”
• “The No Surprises Act should scrap the dispute resolution process in favor of a truth-in-advertising approach that will protect consumers and free doctors, insurers, and arbiters from confused and conflicting standards for resolving disputes that the disputing parties can best resolve themselves.”
• “Prohibit abortion travel funding. Providing funding for abortions increases the number of abortions and violates the conscience and religious freedom rights of Americans who object to subsidizing the taking of life.”
• “Prohibit Planned Parenthood from receiving Medicaid funds. During the 2020–2021 reporting period, Planned Parenthood performed more than 383,000 abortions.”
• “Protect faith-based grant recipients from religious liberty violations and maintain a biblically based, social science–reinforced definition of marriage and family. Social science reports that assess the objective outcomes for children raised in homes aside from a heterosexual, intact marriage are clear.”
• “Allocate funding to strategy programs promoting father involvement or terminate parental rights quickly.”
• “Eliminate the Head Start program.”
• “Support palliative care. Physician-assisted suicide (PAS) is legal in 10 states and the District of Columbia. Legalizing PAS is a grave mistake that endangers the weak and vulnerable, corrupts the practice of medicine and the doctor–patient relationship, compromises the family and intergenerational commitments, and betrays human dignity and equality before the law.”
• “Eliminate men’s preventive services from the women’s preventive services mandate. In December 2021, HRSA [Health Resources and Services Administration] updated its women’s preventive services guidelines to include male condoms.”
• “Prioritize funding for home-based childcare, not universal day care.”
• “ The Office of the Secretary should eliminate the HHS Reproductive Healthcare Access Task Force and install a pro-life task force to ensure that all of the department’s divisions seek to use their authority to promote the life and health of women and their unborn children.”
• “The ASH [Assistant Secretary for Health] and SG [Surgeon General] positions should be combined into one four-star position with the rank, responsibilities, and authority of the ASH retained but with the title of Surgeon General.”
• “OCR [Office for Civil Rights] should withdraw its Health Insurance Portability and Accountability Act (HIPAA) guidance on abortion.”

TOPLINE:

The first year after the diagnosis of systemic lupus erythematosus (SLE) is crucial, with the highest percentage of patients experiencing organ damage. Cardiovascular issues are the second most prevalent after musculoskeletal damage in both early and later stages of SLE.

METHODOLOGY:

• Researchers assessed organ damage persisting at least 6 months over different stages of lupus in 4219 patients with SLE (mean age, 35.9 years; 89.6% women) from the Spanish Society of Rheumatology Lupus Registry.
• Damage was assessed using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI).
• Longitudinal analysis was conducted globally and by each SDI domain on 1274 patients with recorded damage event dates.
• Follow-up data were available out to 10 years in 1113 patients and to 20 years in 601.

TAKEAWAY:

• New damage was recorded in 20% of the patients with SLE within the first year after diagnosis, with the annual percentage of patients with new damage decreasing to 5% after the first 5 years of follow-up.
• In the first year, musculoskeletal damage was reported by the highest proportion of patients (21%), followed by cardiovascular damage inclusive of cerebrovascular accidents and claudication for 6 months (19%).
• The cardiovascular system remained the second most affected system even during the later stages of the diseases at years 10 and 20 of follow-up (20%-25%).
• Apart from musculoskeletal and cardiovascular damage, patients with lupus also showed renal and ocular damage in the early and later stages of the disease, respectively.

IN PRACTICE:

“Our study highlights the importance of cardiovascular damage and the need for its prevention during the earliest stages of the disease,” the authors wrote.

SOURCE:

The study was led by Irene Altabás-González, MD, PhD, Rheumatology Department, Vigo University Hospital Group, Vigo, Spain. It was published online in Lupus Science & Medicine.

LIMITATIONS:

The retrospective collection of data in the study may have led to missing items; for example, the dates of damage events for the whole cohort were not available. 

DISCLOSURES:

The registry was supported by the Spanish Society of Rheumatology. No specific funding was received for the study. The authors declared no conflicts of interest.

The Diagnosis: Brunsting-Perry Cicatricial Pemphigoid

Physical examination and histopathology are paramount in diagnosing Brunsting-Perry cicatricial pemphigoid (BPCP). In our patient, histopathology showed subepidermal blistering with a mixed superficial dermal inflammatory cell infiltrate. Direct immunofluorescence was positive for linear IgG and C3 antibodies along the basement membrane. The scarring erosions on the scalp combined with the autoantibody findings on direct immunofluorescence were consistent with BPCP. He was started on dapsone 100 mg daily and demonstrated complete resolution of symptoms after 10 months, with the exception of persistent scarring hair loss (Figure).

Brunsting-Perry cicatricial pemphigoid is a rare dermatologic condition. It was first defined in 1957 when Brunsting and Perry¹ examined 7 patients with cicatricial pemphigoid that predominantly affected the head and neck region, with occasional mucous membrane involvement but no mucosal scarring. Characteristically, BPCP manifests as scarring herpetiform plaques with varied blisters, erosions, crusts, and scarring.¹ It primarily affects middle-aged men.²

Historically, BPCP has been considered a variant of cicatricial pemphigoid (now known as mucous membrane pemphigoid), bullous pemphigoid, or epidermolysis bullosa acquisita.³ The antigen target has not been established clearly; however, autoantibodies against laminin 332, collagen VII, and BP180 and BP230 have been proposed.^2,4,5 Jacoby et al6 described BPCP on a spectrum with bullous pemphigoid and cicatricial pemphigoid, with primarily circulating autoantibodies on one end and tissue-fixed autoantibodies on the other.

The differential for BPCP also includes anti-p200 pemphigoid and anti–laminin 332 pemphigoid. Anti-p200 pemphigoid also is known as bullous pemphigoid with antibodies against the 200-kDa protein.⁷ It may clinically manifest similar to bullous pemphigoid and other subepidermal autoimmune blistering diseases; thus, immunopathologic differentiation can be helpful. Anti–laminin 332 pemphigoid (also known as anti–laminin gamma-1 pemphigoid) is characterized by autoantibodies targeting the laminin 332 protein in the basement membrane zone, resulting in blistering and erosions.⁸ Similar to BPCP and epidermolysis bullosa aquisita, anti–laminin 332 pemphigoid may affect cephalic regions and mucous membrane surfaces, resulting in scarring and cicatricial changes. Anti–laminin 332 pemphigoid also has been associated with internal malignancy.⁸ The use of the salt-split skin technique can be utilized to differentiate these entities based on their autoantibody-binding patterns in relation to the lamina densa.

Treatment options for mild BPCP include potent topical or intralesional steroids and dapsone, while more severe cases may require systemic therapy with rituximab, azathioprine, mycophenolate mofetil, or cyclophosphamide.⁴

This case highlights the importance of histopathologic examination of skin lesions with an unusual history or clinical presentation. Dermatologists should consider BPCP when presented with erosions, ulcerations, or blisters of the head and neck in middle-aged male patients.

TOPLINE:

Uptake of infliximab biosimilars rose slowly across private insurance, Medicaid, and Medicare when two were available in the United States during 2016-2020 but increased significantly through 2022 after the third biosimilar became available in July 2020. However, prescriptions in Medicare still lagged behind those in private insurance and Medicaid.

METHODOLOGY:

• Researchers analyzed electronic health records from over 1100 US rheumatologists who participated in a national registry, the Rheumatology Informatics System for Effectiveness (RISE), for all infliximab administrations (bio-originator or biosimilar) to patients older than 18 years from April 2016 to September 2022.
• They conducted an interrupted time series to account for autocorrelation and model the effect of each infliximab biosimilar release (infliximab-dyyb in November 2016, infliximab-abda in July 2017, and infliximab-axxq in July 2020) on uptake across Medicare, Medicaid, and private insurers.

TAKEAWAY:

• The researchers identified 659,988 infliximab administrations for 37,560 unique patients, with 52% on Medicare, 4.8% on Medicaid, and 43% on private insurance.
• Biosimilar uptake rose slowly with average annual increases < 5% from 2016 to June 2020 (Medicare, 3.2%; Medicaid, 5.2%; private insurance, 1.8%).
• After the third biosimilar release in July 2020, the average annual increase reached 13% for Medicaid and 16.4% for private insurance but remained low for Medicare (5.6%).
• By September 2022, biosimilar uptake was higher for Medicaid (43.8%) and private insurance (38.5%) than for Medicare (24%).

IN PRACTICE:

“Our results suggest policymakers may need to do more to allow biosimilars to get a foothold in the market by incentivizing the development and entry of multiple biosimilars, address anticompetitive pricing strategies, and may need to amend Medicare policy to [incentivize] uptake in order to ensure a competitive and sustainable biosimilar market that gradually reduces total drug expenditures and out-of-pocket costs over time,” wrote the authors of the study.

SOURCE:

The study was led by Eric T. Roberts, PhD, University of California, San Francisco. It was published online on July 30, 2024, in Arthritis & Rheumatology.

LIMITATIONS:

First, while the biosimilar introductions are likely catalysts for many changes in the market, some changes in slopes may also be attributable to the natural growth of the market over time. Second, this study may neither be generalizable to academic medical centers, which are underrepresented in RISE, nor be generalizable to infliximab prescriptions from other specialties. Third, uptake among privately insured patients changed shortly after November-December 2020, raising the possibility that the delay reflected negotiations between insurance companies and relevant entities regarding formulary coverage.

DISCLOSURES:

This study was funded by grants from the Agency for Healthcare Research and Quality and the National Institute of Arthritis and Musculoskeletal and Skin Diseases. One author disclosed receiving consulting fees from Pfizer, AstraZeneca, and Bristol-Myers Squibb and grant funding from AstraZeneca, the Bristol-Myers Squibb Foundation, and Aurinia.
