Matthew F. Watto, MD: I’m Dr Matthew Frank Watto, here with my great friend and America’s primary care physician, Dr Paul Nelson Williams. 

We had a great discussion with Kidney Boy, Dr Joel Topf, everyone’s favorite nephrologist, and he taught us how to manage blood pressure in chronic kidney disease (CKD).

When should I start freaking out about a patient’s kidney function? 

Paul N. Williams, MD: Dr Topf focuses more on albuminuria than we are used to doing. It’s probably one of the most important prognostic indicators of how a patient is going to do from a renal standpoint.

Historically, I’ve tended to focus on the estimated glomerular filtration rate (eGFR), and the lower that number gets, the more I sweat, but albuminuria is probably equally, if not more, important as a way of prognosticating whether a patient is going to progress to dialysis or transplant. He directed us towards this nifty little calculator, kidneyfailurerisk.com, where you plug in the patient’s age, eGFR, and degree of albuminuria, and it spits out their risk of progressing to hemodialysis or renal transplantation over the next 5 years. It’s a nice way to concretely explain to patients their risk for progression.

Instead of telling the patient, “You are high risk,” Dr Topf will say, “Your risk is 6% of needing dialysis in the next 5 years.” You can even use these thresholds to gauge when to refer a patient. If someone has a 5-year risk between 3% and 5% or higher, that patient should probably be seeing a nephrologist.

If their 2-year risk is greater than 20%, that patient probably should be evaluated for transplantation. This gives us have more concrete numbers to work with rather than just saying, “Your kidneys aren’t working as well as we would like and you should see a kidney doctor.” Patients have a better sense of how serious things might be. 

Watto: It’s just easier for them to understand. Dr Topf made the point that we used to have a heat map based on the stage of CKD that would tell you how high a patient’s risk was compared with other people. But patients don’t really understand relative risk, so Dr Topf tells them their absolute risk for ending up on dialysis over the next 2-5 years. 

Patients come in and they are worried because they looked at their lab results and see that their creatinine level is red, or their eGFR is low. They think, It says I have stage 3a CKD. 

We should probably have the stages of CKD start at stage 3, which should be called stage 1 so it doesn’t sound as bad. Patients think they are halfway to dialysis; they are already at stage 3 and didn’t even know their kidneys were a problem. 

Dr Topf said that cystatin C (something I only recently started ordering) can be obtained, and sometimes you can recategorize the patient, especially those with an eGFR between 45 and 60. The cystatin C can predict their renal function better than the creatinine-based equations. If you are using the creatinine equation, he recommends using the 2021 equations.

Another nice thing about cystatin C is that it isn’t tripped up in younger patients with a lot of muscle mass. You just have to watch out for inflammation, which can throw the test off. For example, when a patient is in the intensive care unit, it’s probably not that helpful, but for your outpatients, cystatin C works well. 

Williams: I’ve been using it a fair amount in my patients with more muscle mass. And some patients have been taking creatine as a supplement, and that can alter the numbers as well. This is a nice way to get them out of CKD stage 2 or 3 and back where they belong, with normal healthy functioning kidneys.

Watto: Now, Paul, if we find a patient with more advanced CKD — let’s say stage 4, whether by cystatin C or serum creatinine, and their eGFR is less than 30 — should we start peeling off the angiotensin-converting enzyme ACE inhibitor or the angiotensin receptor blocker (ARB)? Those drugs can raise potassium. What should we do here? 

Williams: That’s the temptation, Matt, and I feel like that was the old orthodoxy, back in residency. It didn’t take much for us to start taking off ACE inhibitors or ARBs once the kidney function started to drop, but it turns out you may be doing more harm than good.

Some data have shown that if you peel off those medications, you actually increase mortality and cardiovascular risk. So, in general, if you can keep them going, the patient will be better off. Hang onto the ACE inhibitors or ARBs as long as you are able to, because they confer a fair amount of benefit.

Watto: As long as the potassium isn’t in red on your lab’s range. It might go up to 5.2 or 5.4, but as long as it’s stable, that should be OK. You probably wouldn’t initiate an ACE inhibitor or ARB or spironolactone with a potassium level above 5, but if it’s below 5 when you start and it goes up slightly after you start the drug, that could be acceptable. 

Another thing we talked about was when a patient progresses to CKD and ends up on dialysis, how helpful are those intradialysis blood pressures in predicting cardiovascular outcomes? 

Williams: For someone who’s performing the dialysis, probably really helpful. In the outpatient setting to predict cardiovascular risk, probably less so. Dr Topf makes the point that the readings are done either shortly after or right when the patient is about to have a large-bore catheter inserted into their arm. And then they have liters of fluid drained out of them. So those numbers are going to have huge amounts of variability. You would not base the patient’s blood pressure treatment solely on those numbers. But regardless of what the numbers are, or even regardless of your office numbers, hopefully you’re working with a nephrologist to make sure that you’re actually in concert and not fighting each other with the blood pressure medications.

Watto: Dr Topf said that a lot of the hypertension in dialysis is because of too much volume. If you can get the volume down, you might be able to peel off blood pressure medications instead of adding more. But some patients have issues with cramping; it’s uncomfortable and not everyone tolerates it. 

I was really surprised to learn that beta blockers, specifically atenolol, have some evidence of improving cardiovascular outcomes in patients on dialysis. Dr Topf speculated that this was because they are largely dying of cardiovascular disease, so maybe that’s why, but that’s one of the places, the only places I can think of aside from thyroid disease, where atenolol really shines.

NEW YORK CITY — The total body skin examination with or without dermatoscopy might eventually be marginalized by noninvasive technologies that greatly reduce the need for biopsy while increasing sensitivity and specificity, according to an expert describing four such technologies now in routine use at his own institution.

For skin cancer screening, existing and coming technologies represent “the future of dermatology,” but “we can and should be [already] trying to incorporate these into routine practice,” said Jonathan Ungar, MD, assistant professor of dermatology at the Icahn School of Medicine at Mount Sinai, New York City.

 

Technologies such as electrical impedance spectroscopy (EIS), optical coherence tomography (OCT), and reflectance confocal microscopy (RCM) have immediate utility for improving skin cancer detection with fewer biopsies, but this is just the beginning, according to Ungar, who is also medical director of the Kimberly and Eric J. Waldman Melanoma and Skin Cancer Center at Mount Sinai, New York City.

“There is going to be a day when we are not cutting to make a diagnosis,” he said during a presentation at the 27th Annual Winter Symposium — Advances in Medical and Surgical Dermatology (MSWS) 2024.

 

Four Noninvasive Tools Are in Routine Use

Each of these technologies, along with total body photography (TBP), is currently in use at Mount Sinai as well as other tertiary centers to improve diagnostic accuracy at the same time they reduce invasive tests. The initial excitement about these technologies was based on their potential to avoid biopsy in cosmetically sensitive areas, but Ungar suggested that wider application is being driven by better rates of detection, less morbidity, and improved patient satisfaction.

Patients are happy to avoid invasive procedures whenever they can, Ungar noted. In addition to concern about pain or discomfort and a small but measurable risk for infection, patients face a wound that requires healing and the potential for an enduring scar whether the histology is positive for a malignancy.

While none of the four technologies Ungar outlined typically provide a yes or no answer regarding the presence of a malignancy, they do improve diagnostic accuracy with a lower rate of biopsy.

 

Each Noninvasive Tool Reduces Biopsy Rates

In the case of EIS, for example, the impedance of a painless and harmless electrical current directed into the skin with a handheld probe differentiates normal from abnormal skin through an EIS algorithm. Ungar said it does not require training. A result negative for an abnormality has about a 90% predictive value, and it means that a biopsy can be avoided if there are no other reasons for suspicion.

With a price estimated in the thousands of dollars, the device and software are “not so expensive,” particularly when the tool results in fewer biopsies, Ungar noted.

OCT has a similar profile. Again, used as an adjunct to other types of evaluations, including a history and visual inspection, this helps in modulating suspicion of malignancy. In published studies, OCT has proven superior to dermatoscopy for cancer detection. Citing a 14-study meta-analysis, Ungar said that the sensitivity of OCT for melanoma exceeds, and the specificity approaches, 90%. For basal cell cancers, it is even better.

RCM involves directing a laser into the skin to detect abnormal cells that reflect light. It enables visualization of the skin by layers to the papillary dermis in a detail that is comparable with histology, according to Ungar. Imaging performed with the device used at Mount Sinai (VivaScope 1500, Caliber Imaging & Diagnostics) is reimbursed by Medicare.

Once comfortable with the technology, scanning and interpretation take slightly more time than that required of EIS or OCT, but, like the others, it is painless and helpful for determining whether further evaluation is needed, according to Ungar.

“It is extremely useful in reducing the number of biopsies,” whether melanoma or basal cell malignancies, he said.

 

Total Body Photograph Helps With Serial Screens

While not specifically a diagnostic tool, TBP can also play a role in reducing biopsies through its highly efficient ability to document the evolution of lesions over time.

As its name implies, essentially the entire body surface is captured by multiple cameras mounted in a circle around the patient. Unlike sequential photos that require far more time to take and store and are challenging to organize and retrieve, the device used at Mount Sinai (Vectra Wb180 1360, Canfield Scientific) can complete the photos in about 2 minutes.

Software for organizing and storing the photos, to which dermatoscope images of individual lesions can be attached if helpful, results in efficient retrieval of photos at sequential visits for evaluating change in any specific lesion.

“It is very easy to use,” according to Ungar, who noted that although the underlying idea is not, the technology of taking, storing, and retrieving photographs has been “perhaps perfected” with this approach.

 

Noninvasive Screening Training Is Appropriate

Year after year, dermatology residents undergo intensive instruction to master the traditional methods of skin examination with the naked eye and the help of a dermatoscope, but Ungar considers the noninvasive tools to be another step forward. They lower miss rates while reducing the need for histopathology.

Adding these new technologies to routine patient care resonates for many experts, even if the protocols of when to use with the tool are not well established.

Angela J. Lamb, MD, an associate professor of dermatology at Mount Sinai, who has been following the work of Ungar with interest, sees merit in his argument. Not surprisingly, she thinks that any approach shown to boost skin cancer detection is something that deserves attention, but she thinks the effort to safely eliminate biopsies with a low likelihood of a positive finding cannot be ignored.

“Patients want to avoid biopsies when they can,” Lamb told this news organization, and she does not think this is limited to biopsies on the face or other cosmetically sensitive areas.

As a result, she said that she does see the rationale for incorporating the newer technologies into routine care and called this an “important” effort to improve the patient experience as well as reduce missed lesions.

Ungar reported financial relationships with AbbVie, Bristol-Myers Squibb, Castle Biosciences, Dermavant, Janssen Pharmaceuticals, Menlo Therapeutics, Mitsubishi Tanabe Pharma America, and UCB. Lamb reported no potential conflicts of interest.

Ungar said it does not require training. A result negative for an abnormality has about a 90% predictive value, and it means that a biopsy can be avoided if there are no other reasons for suspicion.

With a price estimated in the thousands of dollars, the device and software are “not so expensive,” particularly when the tool results in fewer biopsies, Ungar noted.

OCT has a similar profile. Again, used as an adjunct to other types of evaluations, including a history and visual inspection, this helps in modulating suspicion of malignancy. In published studies, OCT has proven superior to dermatoscopy for cancer detection. Citing a 14-study meta-analysis, Ungar said that the sensitivity of OCT for melanoma exceeds, and the specificity approaches, 90%. For basal cell cancers, it is even better.

RCM involves directing a laser into the skin to detect abnormal cells that reflect light. It enables visualization of the skin by layers to the papillary dermis in a detail that is comparable with histology, according to Ungar. Imaging performed with the device used at Mount Sinai (VivaScope 1500, Caliber Imaging & Diagnostics) is reimbursed by Medicare.

Once comfortable with the technology, scanning and interpretation take slightly more time than that required of EIS or OCT, but, like the others, it is painless and helpful for determining whether further evaluation is needed, according to Ungar.

“It is extremely useful in reducing the number of biopsies,” whether melanoma or basal cell malignancies, he said.

 

Total Body Photograph Helps With Serial Screens

While not specifically a diagnostic tool, TBP can also play a role in reducing biopsies through its highly efficient ability to document the evolution of lesions over time.

As its name implies, essentially the entire body surface is captured by multiple cameras mounted in a circle around the patient. Unlike sequential photos that require far more time to take and store and are challenging to organize and retrieve, the device used at Mount Sinai (Vectra Wb180 1360, Canfield Scientific) can complete the photos in about 2 minutes.

Software for organizing and storing the photos, to which dermatoscope images of individual lesions can be attached if helpful, results in efficient retrieval of photos at sequential visits for evaluating change in any specific lesion.

“It is very easy to use,” according to Ungar, who noted that although the underlying idea is not, the technology of taking, storing, and retrieving photographs has been “perhaps perfected” with this approach.

 

Noninvasive Screening Training Is Appropriate

Year after year, dermatology residents undergo intensive instruction to master the traditional methods of skin examination with the naked eye and the help of a dermatoscope, but Ungar considers the noninvasive tools to be another step forward. They lower miss rates while reducing the need for histopathology.

Adding these new technologies to routine patient care resonates for many experts, even if the protocols of when to use with the tool are not well established.

Angela J. Lamb, MD, an associate professor of dermatology at Mount Sinai, who has been following the work of Ungar with interest, sees merit in his argument. Not surprisingly, she thinks that any approach shown to boost skin cancer detection is something that deserves attention, but she thinks the effort to safely eliminate biopsies with a low likelihood of a positive finding cannot be ignored.

“Patients want to avoid biopsies when they can,” Lamb told this news organization, and she does not think this is limited to biopsies on the face or other cosmetically sensitive areas.

As a result, she said that she does see the rationale for incorporating the newer technologies into routine care and called this an “important” effort to improve the patient experience as well as reduce missed lesions.

Ungar reported financial relationships with AbbVie, Bristol-Myers Squibb, Castle Biosciences, Dermavant, Janssen Pharmaceuticals, Menlo Therapeutics, Mitsubishi Tanabe Pharma America, and UCB. Lamb reported no potential conflicts of interest.

TOPLINE:

InterRhythmic care (IRC), a novel digital intervention, was linked to greater improvements in depressive symptoms, anxiety, interpersonal relationships, and social functioning in patients with major depressive disorder (MDD), compared with internet general psychoeducation in new research.

METHODOLOGY:

• The randomized, single-blind trial included 120 outpatients from the Shanghai Mental Health Center between March and November 2021 with MDD (mean age, 28.2 years; 99% Han Chinese; 83% women) who were randomly assigned to receive either IRC or internet general psychoeducation (control group).
• IRC included computer-based psychoeducation on stabilizing social rhythm regularity and resolution of interpersonal problems plus brief online interactions with clinicians. Patients received 10 minutes of IRC daily, Monday through Friday, for 8 weeks.
• The researchers assessed participants’ depressive symptoms, anxiety symptoms, interpersonal relationships, social function, and biological rhythms using the 17-item Hamilton Depression Rating Scale, Hamilton Anxiety Scale, Interpersonal Comprehensive Diagnostic Scale, Sheehan Disability Scale, and Morning and Evening Questionnaire at baseline and at 8 weeks.

TAKEAWAY:

• The participants who received IRC had significantly lower Hamilton Depression Rating total scores than those who received internet general psychoeducation (P < .001).
• The IRC group demonstrated improved anxiety symptoms, as evidenced by lower Hamilton Anxiety Scale total scores, than those observed for the control group (P < .001).
• The IRC group also showed improved outcomes in interpersonal relationships, as indicated by lower Interpersonal Comprehensive Diagnostic Scale total scores (P < .001).
• Social functioning improved significantly in the IRC group, as measured by the Sheehan Disability Scale subscores for work/school (P = .03), social life (P < .001), and family life (P = .001).

IN PRACTICE:

“This study demonstrated that IRC can improve clinical symptoms such as depressive symptoms, anxiety symptoms, interpersonal problems, and social function in patients with MDD. Our study suggested that the IRC can be used in clinical practice,” the investigators wrote.

SOURCE:

The study was led by Chuchen Xu, Shanghai Mental Health Center, Shanghai Jiao Tong University School of Medicine in China. It was published online on November 20, 2024, in The Journal of Psychiatric Research.

LIMITATIONS:

The 8-week follow-up period was considered too short to comprehensively evaluate the intervention’s long-term impact. Additionally, the researchers had to check and supervise assignment completion, which increased research costs and may, therefore, potentially limit broader implementation.

DISCLOSURES:

The investigators reported no conflicts of interest.

Ringworm (also known as tinea, jock itch, or athlete’s foot) is a common infection caused by dermatophyte fungi, known to affect skin, hair, or nails. It causes skin infections that are typically mild and are often treated with topical antifungals.

However, in recent years, newly emerging dermatophyte strains have been causing more severe and harder-to-treat ringworm. Notably, one emerging strain, Trichophyton mentagrophytes genotype VII(TMVII), is associated with sexual contact. In recent years, TMVII infections linked to sexual contact have been reported among men who have sex with men in Europe and in travelers returning from Southeast Asia. The first US case of TMVII was reported in June 2024, after which public health authorities were alerted to additional cases; all were associated with recent sexual contact. Other dermatophyte species have also been reported to cause ringworm transmitted through sexual contact. 

Here are some key points to know about sexually transmitted ringworm. 

Tell me more about sexually transmitted ringworm: What is causing it?

Skin-to-skin contact is a common mode of ringworm transmission. In recent years, transmission of ringworm via intimate or sexual contact has been increasingly recognized. However, clinicians may not immediately consider ringworm when evaluating genital, facial, or perianal lesions. Infections with sexually transmitted TMVII commonly cause lesions on anatomical sites that may be exposed during intimate or sexual contact, such as the face, genitals, and perianal region. Sexual transmission of TMVII has been reported in Europe, predominantly among men who have sex with men, for several years. Other dermatophyte strains have been reported in association with sexual contact, including the emerging strain Trichophyton indotineae. However, sexual transmission is not the main mode of transmission for T indotineae and other dermatophyte strains. 

When should clinicians suspect a potential case of sexually transmitted ringworm?

Providers should consider sexually transmitted ringworm when seeing ringworm in locations associated with intimate contact (for example, a rash on or around the genitals, perianal area, or mouth). 

The typical appearance of ringworm is a raised, ring-like, erythematous rash with a scaly border that grows over time. The rash may appear pink, brown, or gray on different types of skin. Patients may note itching and flaking of the rash. In areas with hair such as the beard area, ringworm can present as pustules and be associated with hair loss.

Emerging ringworm infections can present in atypical or more severe ways, including a highly inflammatory (painful, scarring, or otherwise severe) rash, a rash affecting a large area or multiple sites, nodules, and pustules. 

Sexually transmitted ringworm may be considered based on sexual history and recent sexual contact with someone with known TMVII. Recent history of travel to a region with reported sexually transmitted ringworm may increase suspicion of TMVII. In patients with a travel history to South Asia, T indotineae should be considered, especially if the rash does not improve with oral terbinafine. 

How can testing help guide the diagnosis of sexually transmitted ringworm infection?

When evaluating a rash that may represent ringworm, providers should use a confirmatory test such as potassium hydroxide (KOH) preparation when possible. KOH prep can confirm the presence of a fungus that causes ringworm, but it does not identify the species or type of ringworm. Testing such as fungal culture and molecular testing can help identify specific types of ringworm, but these tests are not often performed and may take a long time to yield results.

Routine fungal cultures cannot identify TMVII and T indotineae; these tests may identify the genus Trichophyton, but only advanced molecular testing, which is available at selected US laboratories, can identify TMVII and T indotineae. 

We recommend confirmatory testing because ringworm can easily be misdiagnosed as skin conditions such as psoriasis or eczema. The use of topical steroids can worsen a ringworm infection, so clinicians should be cautious about treating a rash with topical steroids if the etiology is unclear. Treatment should not be delayed if testing is not available. 

Clinicians who suspect a case of TMVII infection or infection with another emerging type of severe or antifungal-resistant ringworm can contact the Centers for Disease Control and Prevention (CDC) at [email protected]. More details on how clinicians can pursue testing to identify emerging strains of ringworm can be found on the American Academy of Dermatology (AAD) emerging diseases task force website. 

How should clinicians treat and manage sexually transmitted ringworm? 

If TMVII infection is suspected, providers can consider starting empirical treatment with oral terbinafine. Although data are limited, experience from case series suggests that TMVII may require oral antifungal treatment because it can cause severe skin infections and often does not improve with topical antifungals. Clinicians should advise patients that they may need prolonged treatment courses until the rash resolves, with possible need for treatment courses of 6-8 weeks or longer. 

Any diagnosis of a sexually transmitted infection is an opportunity to engage patients in comprehensive sexual health services. Patients with suspected sexually transmitted ringworm should be evaluated for HIV and other sexually transmitted infections, including syphilis, chlamydia, and gonorrhea; clinicians should discuss and facilitate access to other preventive services, such as HIV pre-exposure prophylaxis if the patient is HIV negative and at risk for HIV. Patients should also notify their partner(s) about the diagnosis. 

Is sexually transmitted ringworm a public health concern? 

It is important to know that very few cases of TMVII have been reported in the United States thus far. CDC continues to monitor emerging dermatophyte strains because these types of ringworm can cause more severe or difficult-to-treat infections. Clinicians should be aware of the potential severity of sexually transmitted ringworm infections and of how diagnosis and treatment of these infections may differ from typical management of ringworm.

So far, TMVII, the dermatophyte strain most associated with spread through sexual contact, has not been documented to have antifungal resistance. More rarely, sexually transmitted ringworm may be caused by other emerging dermatophyte strains that are antifungal resistant, such as T indotineae. Itraconazole is the recommended first-line treatment for T indotineae infections. 

How can clinicians counsel patients with sexually transmitted ringworm?

Ringworm can spread with skin-to-skin contact, so patients should avoid such contact with others while they have a rash. They should also avoid sharing personal items (such as razors or towels) and clothing, and launder their clothing, towels, and bedding in a high heat cycle. 

People can reduce their risk of getting all types of ringworm infection by keeping their skin clean and dry, changing their socks and underwear daily, and wearing sandals in public locker rooms and other public spaces. People should avoid skin-to-skin contact with anyone with ringworm or an unexplained rash. Before having sex, people can check in with their partners and be aware of unexplained rashes on their partners’ bodies.

Where can clinicians go to learn more about sexually transmitted and other emerging types of ringworm?

CDC has partnered with the AAD to create set of online resources for clinicians for diagnosing and managing emerging dermatophyte infections. Clinicians who suspect or confirm antimicrobial resistant ringworm infection are also encouraged to submit cases to the AAD’s Emerging Diseases Registry. Clinicians wanting further guidance on how to manage suspected or confirmed ringworm infection with an emerging dermatophyte strain can also contact the CDC at [email protected]. Useful information on emerging dermatophyte infections for providers and patients is also available on CDC’s website.

CDC has partnered with the AAD to create set of online resources for clinicians for diagnosing and managing emerging dermatophyte infections. Clinicians who suspect or confirm antimicrobial resistant ringworm infection are also encouraged to submit cases to the AAD’s Emerging Diseases Registry. Clinicians wanting further guidance on how to manage suspected or confirmed ringworm infection with an emerging dermatophyte strain can also contact the CDC at [email protected]. Useful information on emerging dermatophyte infections for providers and patients is also available on CDC’s website.

TOPLINE:

A survey of dermatologists reveals hypertrophic or traumatic scars, acne, and hyperhidrosis as the top pediatric cosmetic concerns, and vascular lasers, laser hair removal, and lasers for pigmentation among the most common treatments.

METHODOLOGY:

• An anonymous online survey conducted with SurveyMonkey targeted healthcare providers who routinely used lasers to treat cutaneous conditions in pediatric patients.
• The survey included members of the Society for Pediatric Dermatology and the American Society for Laser Medicine and Surgery and Surgery, as well as fellowship directors and current fellows of the American Society for Dermatologic Surgery.
• A total of 85 practitioners responded to the survey, with 86% answering all questions; respondents primarily included pediatric dermatologists (77.65%), general dermatologists (18.82%), cosmetic dermatologists (8.24%), and dermatologic/Mohs surgeons (1.18%).

TAKEAWAY:

• Hypertrophic or traumatic scars ranked as the most frequently treated pediatric cosmetic condition (95.29%), followed by acne (89.41%), axillary and facial hyperhidrosis (77.65%), hypertrichosis/hirsutism (67.06%), and pigmented lesion removal (64.71%).
• The most common procedures performed were vascular lasers (77.65%), laser hair removal (50.59%), lasers for pigmentation (28.24%), neuromodulators (25.88%), and laser skin resurfacing (22.35%).
• Additional treatments respondents performed included chemical peels (20.00%), radiofrequency microneedling (16.47%), soft tissue fillers (4.71%), and cryolipolysis/body contouring (4.17%).
• About 50% of respondents said they would start cosmetic treatment of acne, and about 66% said they would start laser hair removal treatment between the ages of 12 and 15 years.

IN PRACTICE:

Noting that the survey results provided insight into the types of cosmetic procedures being performed for pediatric patients, the authors wrote, “These interventions can play a significant role in addressing the emotional and social challenges faced by pediatric patients with cosmetic concerns, allowing them to navigate social interactions more confidently and positively.” Before any procedure, they added, “It is important that any comorbid conditions be addressed,” they added, and “ethical considerations regarding informed consent, patient autonomy, and long-term consequences should be carefully weighed, given the vulnerable nature of pediatric patients.”

SOURCE:

The study was led by Lauren Hoffman, MD, who practices dermatology in Great Neck, New York. It was published online in December 2024 in Dermatologic Surgery.

LIMITATIONS:

The study was subjective in nature and had a small sample size, and the exact number of survey recipients was unclear, hindering an accurate calculation of the response rate. The absolute number of responses accounted for a small portion of the total memberships of the participating societies. Also, the data collection periods varied among the three academic societies, and dermatologists’ practice types may have influenced the range and nature of treated conditions.

DISCLOSURES:

The authors did not disclose funding information. They declared no conflicts of interest.

The Food and Drug Administration (FDA) has approved nemolizumab for moderate to severe atopic dermatitis inadequately controlled with topical therapies in patients aged 12 years and older, according to a press release from the manufacturer, Galderma. 

Nemolizumab (Nemluvio), a monoclonal antibody administered subcutaneously, targets the interleukin (IL)–31 receptor. IL-31 is known to promote itching and inflammation in atopic dermatitis, according to the company. 

Approval was based on data from the phase 3 ARCADIA 1 and ARCADIA 2 clinical trials, recently published in The Lancet, which included 1728 patients aged 12 years and older with moderate to severe atopic dermatitis and pruritus who had an inadequate response to topical steroids. 

At week 16, significantly more patients randomized to nemolizumab every 4 weeks met the co-primary endpoints, compared with those taking placebo. The co-primary endpoints were an Investigator Global Assessment (IGA) score of 0 (clear skin) or 1 (almost clear skin), with an improvement of at least 2 points from baseline to 16 weeks, and an improvement of at least 75% on the Eczema Area and Severity Index score from baseline to 16 weeks (EASI-75 response). All patients in both trials also received background treatment with topical corticosteroids and/or topical calcineurin inhibitors.

At 16 weeks, 36% and 38% of patients taking nemolizumab met the IGA criteria in ARCADIA 1 and ARCADIA 2, respectively, compared with 25% and 26% of those taking placebo. Similarly, 44% and 42% of those taking nemolizumab in ARCADIA 1 and ARCADIA 2, respectively, achieved EASI-75, compared with 29% and 30% of those taking placebo. Differences between treatment and placebo groups were significant in both studies. 

In addition, patients reported significant improvement in all key secondary endpoints, including itch, as early as week 1, and improvement in sleep by week 16, according to the study findings.

Safety profiles were similar between the treatment and placebo groups in both studies; the most common adverse reactions (reported by at least 1% of patients in each group) were headache (5% vs 4%), followed by arthralgia, urticaria, and myalgia (2% or less). In ARCADIA 1 and ARCADIA 2, 50% and 41% of patients taking nemolizumab reported at least one treatment-emergent adverse event, similar to the placebo groups (45% and 44%, respectively). 

Serious treatment-emergent adverse events occurred in 1% and 3% of those taking nemolizumab in ARCADIA 1 and ARCADIA 2, respectively, and 1% in the placebo groups in both studies. Ten serious treatment-emergent adverse events potentially related to nemolizumab were reported in five patients in ARCADIA 2. No deaths were reported in either study.

According to the prescribing information, safety profiles were similar between treatment and placebo groups in the subset of adolescents aged 12-17 years.

In August 2024, the FDA approved nemolizumab for the treatment of prurigo nodularis in adults. Authorization applications for nemolizumab for atopic dermatitis and prurigo nodularis are under review by regulatory authorities in Australia, Singapore, Switzerland, Canada, Brazil, and South Korea, according to Galderma.

SAN DIEGO — In patients with metabolic dysfunction–associated steatotic liver disease (MASLD), hypertension, and cirrhosis, certain antihypertensive medications may lead to increased risks for hepatocellular carcinoma (HCC), according to new research.

In particular, the use of calcium channel blockers (CCBs), angiotensin-converting enzyme (ACE) inhibitors, and angiotensin receptor blockers (ARBs) was associated with a higher risk of developing HCC, compared with not using these medications.

About half of patients with MASLD have hypertension, and the use of antihypertensives in these patients is beneficial to reduce the risk for cardiovascular disease and complications related to MASLD, said lead author Ahmed Elhariri, MD, a research fellow at the University of Texas MD Anderson Cancer Center, Houston, who conducted the study as a research assistant in gastroenterology and hepatology at the Baylor College of Medicine, also in Houston.

However, previous studies have suggested a possible link between these medications and cancer development, “especially CCBs and breast and lung cancer,” said Elhariri, who presented the findings at The Liver Meeting 2024: American Association for the Study of Liver Diseases (AASLD).

 

Analyzing Potential Risks

In a case-control study, Elhariri and colleagues analyzed antihypertensive medication use among patients with MASLD-induced HCC, as defined by histology or radiology based on the Liver Imaging Reporting & Data System, and control patients with MASLD but without HCC.

Between 2020 and 2024, the research team recruited 153 newly diagnosed HCC cases with different etiologies and 170 patients with MASLD but without HCC from Baylor College of Medicine’s outpatient clinics. For this study, they selected 47 age- and sex-matched pairs, all of whom had cirrhosis. Only those with a history of hypertension were included, however. Data on risk factors of metabolic syndrome (including diabetes) and HCC were collected, along with details about medication use such as metformin and statins.

A total of 42 patients with MASLD and HCC and 39 MASLD control individuals had a history of hypertension and were treated with antihypertensive medications. The mean age was 66.5 years for the HCC group and 63.5 years for the control group, and the mean body mass index (BMI) was 31.1 for the HCC group and 31.7 for the control group.

After adjusting for age, sex, BMI, Hispanic ethnicity, and use of other medications, patients taking CCBs had an increased HCC risk (odds ratio [OR], 2.76), compared with those not taking CCBs. Patients taking ACE inhibitors or ARBs also had an increased HCC risk (OR, 2.54), compared with those not taking ACE inhibitors or ARBs.

However, there wasn’t a statistically significant difference in HCC risk among patients taking beta-blockers (OR, 0.87).

“Patients with fatty liver in the presence of metabolic syndrome, especially in the presence of cirrhosis and antihypertensives, need to have stricter surveillance for liver cancer,” Elhariri said.

“We need to carefully review blood pressure medications in patients with MASLD and cirrhosis,” he said. CCBs, ACE inhibitors, and ARBs can be replaced with beta-blockers, “which have been shown to reduce progression of cirrhosis-related complications.”

 

Considering Clinical Implications

“Although our study showed some association between the use of some commonly used antihypertensives and the risk for HCC in this high-risk population, it is based on data collected retrospectively on a small number of selected patients with advanced liver disease,” Elhariri noted.

The associations and underlying mechanisms should be studied in larger populations and prospective trials, he said. “Until we have more data with a significantly larger sample size, it’s premature to raise the concern in the general population.”

“The cardiovascular benefits of controlling blood pressure far outweigh the risk of liver cancer in patients with metabolic syndrome,” Elhariri added.

In ongoing studies, researchers are investigating ways to improve patient outcomes and reduce the negative effects of cirrhosis-associated complications among patients with MASLD and metabolic dysfunction–associated steatohepatitis (MASH), Muhammad Ali Butt, MD, a hepatology fellow at Beth Israel Lahey Hospital & Medical Center in Burlington, Massachusetts, said in an interview.

Butt, who wasn’t involved with this study, presented separate research on statins in MASH patients with cirrhosis, which indicated statistically significant decreases in portal hypertension, thrombosis, hepatorenal syndrome, hepatic encephalopathy, and mortality.

“We know patients with MASLD- and MASH-associated cirrhosis commonly have other comorbidities, including high cardiovascular risks, diabetes, and hyperlipidemia,” he said. “All of these conditions indicate patients to be on other medications such as antihypertensives or statins. It’s important to know the role these medications play, especially given the high-risk profile of these patients.”

Elhariri and Butt reported no relevant disclosures.

Butt, who wasn’t involved with this study, presented separate research on statins in MASH patients with cirrhosis, which indicated statistically significant decreases in portal hypertension, thrombosis, hepatorenal syndrome, hepatic encephalopathy, and mortality.

“We know patients with MASLD- and MASH-associated cirrhosis commonly have other comorbidities, including high cardiovascular risks, diabetes, and hyperlipidemia,” he said. “All of these conditions indicate patients to be on other medications such as antihypertensives or statins. It’s important to know the role these medications play, especially given the high-risk profile of these patients.”

Elhariri and Butt reported no relevant disclosures.

NEW YORK CITY — Instructions on wound healing often involve disturbing photographs of severe diabetic ulcers, angry autoimmune blistering, and oozing lesions produced by uncommon genetic disorders, but whether or not they are dramatic, day-to-day dermatologic wound care relies on both the basics as well as novel approaches, according to a well-known wound treatment expert.

Wound repair is relevant to any specialty involved in invasive interventions, but dermatologists are at ground zero and should have commensurate skills, suggested Robert S. Kirsner, MD, PhD, director of the Wound Clinic at Jackson Memorial Hospital and chair of the Department of Dermatology and Cutaneous Surgery at the University of Miami, Florida.

“We as a specialty make and repair more wounds than any other specialty,” said Kirsner, who provided data to make his point. In a table he showed, the number of wound repairs made annually by dermatologists was several-fold higher than surgeons, the next highest group, and the numbers declined rapidly from there. 

Speaking at the 27th Annual Winter Symposium – Advances in Medical and Surgical Dermatology (MSWS) 2024, Kirsner offered an array of clinical pearls, reinforced some basics, and pointed to well-supported strategies he believes are too often overlooked.

Drugs Repurposed for Wound Healing

Of the clinical pearls, he spoke of the repurposing of several agents for wound care. His first example was the monoclonal antibody dupilumab, which inhibits interleukin-4 (IL-4) and IL-13 signaling, to heal selected patients with leg ulcers. The potential of this drug for wound healing was based on a patient with a leg ulcer who presented with concomitant prurigo nodularis and biliary cirrhosis. When offered for the comorbidities, dupilumab provided a “dramatic” benefit with regard to the wound, according to Kirsner. 

The explanation for the response is that IL-4 and IL-13 have been found to be upregulated in some patients with leg ulcers. Based on numerous cases, Kirsner spoke of a phenotype of nonhealing leg ulcers from which elevated IL-4 and IL-13 can be isolated; these are the candidates for adding dupilumab to wound care, he said.

Topical beta-blockade is another example of a therapy repurposed for wound healing, according to Kirsner. He said beta-blockers are already a standard of care for burn wounds, but the mechanism is relevant in other wound types.

Several studies have looked at this phenomenon, with experimental studies showing that skin healing is impaired when beta-2 receptors are agonized but accelerated when blocked. 

 

Beta-Blockade Accelerates Wound Healing 

A recent review of these mechanisms in soft-tissue wound healing pointed to an anti-inflammatory effect, acceleration of keratinocyte migration, pro-reepithelization effects, and inhibition of bacterial virulence. Beta-blockers were first implicated as mediators of wound healing more than a decade ago, but Kirsner indicated that there is now more attention to this therapy within a comprehensive approach in difficult cases.

Although not specific to wound healing, the potential for teprotumumab to improve control of pretibial myxedema is another example of a repurposed therapy for a challenging skin disease. Teprotumumab, a monoclonal antibody that targets the insulin-like growth factor-1 (IGF-1) receptor, is approved for active thyroid eye disease, but Kirsner cited data showing compelling evidence of benefit in this cutaneous complication of Graves disease.

As for basics, Kirsner devoted some time to emphasizing the importance of compression therapy for improving leg vascularization. This is not something to just consider; rather, he thinks it is part of standard practice. “Compress all leg ulcers,” was Kirsner’s simple message.

Citing encouraging work in identifying targetable molecular events in wound healing, Kirsner suggested that treatment might be increasingly guided by biomarkers. He pointed to ongoing work to characterize wound exudate as a source of biomarkers.

“The discarded dressing contains a wealth of information,” he said, referring to cell types and proteins, such as growth factors. He thinks that the ongoing studies of exudate, which have shown that molecular processes detected at the periphery are often different than those at the focal site of injury, have substantial promise for identifying new treatment targets.

 

Virtual Reality to Address Pain

From a practical standpoint, Kirsner looked to a well-studied but still underused adjunct to wound debridement and surgical repair: the distraction offered by relatively low-priced virtual reality systems. He described it as a simple way to help patients keep their minds off the pain. It is not a new idea and has been studied for this use numerous times, and the evidence of benefit is essentially uniform, according to Kirsner.

He said effective and sophisticated systems can now be purchased for just hundreds of dollars, and no training is needed. Indeed, he said pediatric patients can typically explain how the system works if the clinician does not know.

“If you can enhance their experience [during wound repair], you can make their lives and your life better,” he said. 

Joshua Zeichner, MD, associate professor of dermatology at Mount Sinai Hospital in New York City, concurred that the evidence supports this approach and is easy to do. “I am in favor of anything that improves the experience of the patient,” said Zeichner, who chaired the portion of the meeting during which Kirsner spoke. 

Kirsner said he practices what he preaches. “I routinely employ virtual reality for simple surgical procedures or processes that patients might find unpleasant,” he said. He acknowledged that clinicians might have heard this message before, but he believes those who have not yet introduced this into their practice should consider it.

Kirsner has reported no relevant financial relationships. Zeichner has reported serving as a consultant for Beiersdorf.
