With rates of syphilis rising quickly in the United States and elsewhere, clinicians are having to up their game when it comes to diagnosing and treating an infection that they may not be paying enough attention to.

More than 200,000 cases of syphilis were reported in the United States in 2022, which is the highest number since 1950 and is a 17.3% increase over 2021, according to the latest figures from the Centers for Disease Control and Prevention (CDC). The rate of infection has increased almost every year since a historic low in 2001.

And the trend is not limited to the United States. Last year, the infection rate in the United Kingdom hit a 50-year high, said David Mabey, BCh, DM, from the London School of Hygiene and Tropical Medicine. Syphilis and other sexually transmitted infections are also a major problem in low- and middle-income countries, he added, although good data are not always available.

Many of today’s healthcare professionals have little experience with the disease, shared Ina Park, MD, a sexually transmitted infections specialist at the University of California at San Francisco. “An entire generation of physicians — including myself — did not see any cases until we were well out of our training,” Dr. Park reported. “We’re really playing catch-up.”
 

A Centuries-Old Ailment

Dr. Park offered some advice on the challenges of diagnosing what can be an elusive infection at the Conference on Retroviruses and Opportunistic Infections (CROI) 2024 Annual Meeting in Denver. That advice boiled down to one simple rule: “Test, test, test.”

Because syphilis can mimic so many other conditions and can have long periods of latency, it can be easily missed or even misdiagnosed by experienced physicians, said Dr. Park. Clinicians need to keep it front of mind and have a lower threshold for testing, even if there are no obvious symptoms.

Following the CDC’s new recommendations for syphilis screening will help, she noted; every sexually active patient aged between 15 and 44 years who lives in a county with a syphilis infection rate of 4.6 per 100,000 people or higher should get the test. And clinicians should remain vigilant, even in areas with a lower prevalence. “If you can’t account for new symptoms in a sexually active patient, order a test,” said Dr. Park.
 

Complicated Cases

The lack of experience with syphilis affects not just diagnosis but also treatment, particularly for complex cases, said Khalil Ghanem, MD, PhD, from the Johns Hopkins University School of Medicine in Baltimore. “When you don’t have to deal with something for a while, you forget how to deal with it,” he added.

At CROI, Dr. Ghanem offered suggestions for how to navigate complicated cases of ocular syphilis, otic syphilis, and neurosyphilis, and how to interpret test results when a patient’s antigen titers are being “unruly.”

With potential ocular or otic syphilis, you shouldn’t wait for a specialist like an ophthalmologist to weigh in but instead refer the patient directly to the emergency department because of the risk that the symptoms may become irreversible and result in permanent blindness or deafness. “You don’t want to dilly-dally with those conditions,” Dr. Ghanem said.

Closely monitoring a patient’s rapid plasma regain and venereal disease research laboratory antigen levels is the only way to manage syphilis and to determine whether the infection is responding to treatment, he noted, but sometimes those titers “don’t do what you think they should be doing” and fail to decline or even go up after treatment.

“You don’t know if they went up because the patient was re-infected, or they developed neurosyphilis, or there was a problem at the lab,” he said. “It can be challenging to interpret.”

To decipher confusing test results, Dr. Ghanem recommended getting a detailed history to understand whether a patient is at risk for reinfection, whether there are signs of neurosyphilis or other complications, whether pregnancy is possible, and so on. “Based on the answers, you can determine what the most rational approach to treatment would be,” he shared.
 

Drug Shortages

Efforts to get the infection under control have become more complicated. Last summer, Pfizer announced that it had run out of penicillin G benzathine (Bicillin), an injectable, long-acting drug that is one of the main treatments for syphilis and the only one that can be given to pregnant people. Supplies for children ran out at the end of June 2023, and supplies for adults were gone by the end of September.

Because Pfizer is the only company that manufactures penicillin G benzathine, there is no one to pick up the slack in the short-term, so the shortage is expected to continue until at least the middle of 2024.

In response, the US Food and Drug Administration has temporarily allowed the use of benzylpenicillin benzathine (Extencilline), a French formulation that has not been approved in the United States, until supplies of penicillin G benzathine are stabilized.

The shortage has shone a spotlight on the important issue of a lack of alternatives for the treatment of syphilis during pregnancy, which increases the risk for congenital syphilis. “Hopefully, this pushes the National Institutes of Health and others to step up their game on studies for alternative drugs for use in pregnancy,” Dr. Ghanem said.

TOPLINE:

A study found that 94% of best-selling baby cleansers contain allergens, despite their hypoallergenic claims.

METHODOLOGY:

• Many baby cleansers are marketed as “hypoallergenic,” but these claims are not validated. 
• This study assessed the potential allergens and marketing claims in best-selling baby cleansers. 
• The researchers collected ingredients and marketing claims of the top 50 best-selling baby body wash products sold on Amazon on April 4, 2023. 
• Ingredient lists were checked for potential allergens using the 2020 American Contact Dermatitis Society (ACDS) core allergen series, which lists 90 common allergens for adults and children.

TAKEAWAY:

• In the 50 cleansers tested, 10 allergens were identified. Overall, 94% of the cleansers contained at least one allergen, averaging 2.9 allergens per product; cocamidopropyl betaine  (72%), fragrance (64%), and sodium benzoate (54%) were the most common allergens. 
• All cleansers had at least five marketing claims, with an average of 10.9 claims per product; the most common claims were “paraben-free” (88%), “phthalate-free” (84%), “tear-free” (74%), and “hypoallergenic” or “allergy-tested” (74%). 
• There was no significant difference in the number of allergens in the cleansers marketed as “hypoallergenic” or “allergy tested” compared with cleansers that did not have these claims (P = .843).
• Fewer allergens were found in cleansers endorsed by the National Eczema Association (P = .004) or labeled “synthetic fragrance-free” (P = .003).
• There was a positive correlation between a greater number of allergens and an increased number of marketing claims (r = 0.547, P < .001) and a negative correlation between cost and number of allergens (r = −0.450, P = .001).

IN PRACTICE:

Because marketing claims like “hypoallergenic” may be misleading, “clinicians should counsel parents to carefully examine cleanser ingredients or consider selecting cleansers” endorsed by the National Eczema Association or another international eczema organization, especially for infants and children with a history of atopic dermatitis, the authors wrote. 

SOURCE:

The study, led by Sasan D. Noveir, BA, from the University of California, Los Angeles, and coauthors from the division of dermatology at UCLA, was published online in Pediatric Dermatology.

LIMITATIONS:

The study only evaluated top-selling products from a single online source at a specific time, which may limit generalizability. Potential allergens not included in the ACDS core series may be present.

DISCLOSURES:

The study did not disclose any funding source. The authors declared no conflicts of interest.

FROM AAD 2024

SAN DIEGO — In separate studies evaluating treatments for severe forms of alopecia, inhibitors of Janus kinases (JAKs) produced clinically meaningful hair regrowth, according to late-breaking data presented at the annual meeting of  the American Academy of Dermatology.

In one study of brepocitinib, the target was cicatricial alopecia (CA), a form of hair loss for which there are no approved therapies. In the other, a subanalysis from phase 3 trials of ritlecitinib for alopecia areata (AA), hair regrowth was shown in the subset of patients who entered the study with alopecia totalis or alopecia universalis (AT/AU).

Reflecting comments from several experts, including one of the late-breaking session moderators, April W. Armstrong, MD, MPH, professor and chief of dermatology, University of California, Los Angeles, said that the CA study, which matched clinical response to changes in CA biomarkers, suggested that the results are a potential breakthrough.

“This is the first placebo-controlled study with an oral JAK inhibitor that not only shows that scarring alopecia can be reversible but also gives insights to the mechanism of action and which patients might respond best,” Emma Guttman-Yassky, MD, PhD, said in an interview. Dr. Guttman-Yassky, professor of Dermatology and Immunology, and director of the Laboratory of Inflammatory Skin Diseases, Icahn School of Medicine at Mount Sinai, New York City, was the study’s senior investigator.

Scarring Alopecia and Brepocitinib

For the study of scarring alopecia, 49 patients with CA were randomized in a 3:1 ratio to brepocitinib, a first-in-class inhibitor that targets both JAK1 and TYK2, or placebo. Because of the small size of the study, the primary endpoint was the change in CA biomarkers. The secondary outcome was clinical response, but because of a correlation between the two, these were mutually reinforcing.

Of the subtypes, nine patients enrolled in the study had frontal fibrosing alopecia (FFA), 16 had lichen planopilaris (LPP) alopecia, and 24 had central centrifugal cicatricial alopecia (CCCA). All of the forms of CA are more common in women overall and women of color specifically, particularly CCCA. For this analysis, the FFA and LPP subtypes were considered similar for assessing response and were combined.

The data included a comparison of response and safety during the 24-week randomization phase, as well as an additional follow-up conducted after another 24 weeks of open-label treatment. During the second phase, all patients on placebo were switched to active treatment.

Overall, there was a reduction in all four of the key scalp inflammatory biomarkers measured among those in the combined FFA/LLP group. In the placebo group, each of these markers — interferon gamma (IFN-gamma), CCLS, CXCL10, and STAT1 — increased over the same time period. In almost all cases, the differences were statistically significant.

In the CCCA subgroup, the same pattern (an increase among those on placebo but a decrease among those on brepocitinib) was observed for CCLS and CXCL10. For IFN-gamma and STAT1, a rise was observed among those on placebo and those on active treatment, although the rise was greater for placebo.

For clinical response, improvement on brepocitinib was observed on disease activity indexes, particularly among those in the FFA/LLP group, according to Marguerite Meariman, MD, a dermatology resident at Mount Sinai, who presented the results. She called the improvement in clinical activity scores at 48 weeks “dramatic.” Moreover, improvement was apparent within 4 weeks of starting therapy.

For CCCA, a more challenging condition to treat, Dr. Meariman said that no further progression might represent an acceptable response for many patients, but there were also cases of hair regrowth in this subset. Although improvement was not generally on the order seen among those with FFA/LLP, she suggested that there is promise even in these more difficult patients.

Further studies are planned, but Dr. Meariman said that it might be important to focus on early treatment regardless of CA subtype. She noted that patients with less than 5 years disease duration typically did better than those with longer durations.

Ritlecitinib for AT/AU

The analysis of patients with AT/AU was based on a subset analysis from the ALLEGRO phase 2b/3 study of ritlecitinib, which targets JAK3 and TEC kinases. The full results of the ALLEGRO trial were published last year in The Lancet. In the new late-breaker analysis, Severity of Alopecia Tool (SALT) scores were evaluated on an observed or last-observation-carried-forward basis. Generally, responses in the subgroup of patients with AT/AU, who had a median SALT score of 80.3 (signifying 80.3% hair loss) at baseline, were only modestly lower than those in the overall trial.

At 24 months, about 50% of patients achieved a SALT score of 20, according to Melissa Piliang, MD, chair of Dermatology at the Cleveland Clinic, Cleveland, Ohio, who presented the data. In this group, as in the non-AT/AU population, responses climbed over time, and these responses have been maintained for as long as patients have remained on therapy.

At the more rigorous threshold of SALT < 10, the proportion of responders was only slightly lower, meaning a substantial proportion of patients with AT/AU “are achieving 90% or more of hair regrowth, so really an excellent response,” Dr. Piliang said.

For the subgroup with AU, specifically, regrowth of eyebrows and eyelashes was also observed in a substantial proportion, according to Dr. Piliang. Attributed to the often-devastating psychological burden of hair loss, patient-reported assessments of these responses global were generally “even better” than those reported by the investigators.

However, Dr. Piliang advised clinicians to treat AA as early as possible. Despite the benefits seen in the AT/AU subgroup, she pointed out that starting treatment before total hair loss is associated with a higher likelihood of complete or nearly complete hair regrowth.

There are no data from the ALLEGRO trial to determine how long hair regrowth persists after discontinuation of ritlecitinib, which has been approved for the treatment of AA, but Dr. Piliang said that patients should be told that lifelong therapy should be expected in the vast majority of individuals, whether or not AA has advanced to AT/AU.

“In my experience with JAK inhibitors, you lose response when you come off these drugs,” she said.

Dr. Meariman reported a financial relationship with AbbVie. Dr. Piliang reported financial relationships with Eli Lilly, Pfizer, and Proctor & Gamble. Dr. Armstrong reported financial relationships with more than 30 pharmaceutical companies, including those that manufacture JAK inhibitors. Dr. Guttman-Yassky reported financial relationships with more than 30 companies, including those that manufacture JAK inhibitors.

Although improvement was not generally on the order seen among those with FFA/LLP, she suggested that there is promise even in these more difficult patients.

Further studies are planned, but Dr. Meariman said that it might be important to focus on early treatment regardless of CA subtype. She noted that patients with less than 5 years disease duration typically did better than those with longer durations.

Ritlecitinib for AT/AU

The analysis of patients with AT/AU was based on a subset analysis from the ALLEGRO phase 2b/3 study of ritlecitinib, which targets JAK3 and TEC kinases. The full results of the ALLEGRO trial were published last year in The Lancet. In the new late-breaker analysis, Severity of Alopecia Tool (SALT) scores were evaluated on an observed or last-observation-carried-forward basis. Generally, responses in the subgroup of patients with AT/AU, who had a median SALT score of 80.3 (signifying 80.3% hair loss) at baseline, were only modestly lower than those in the overall trial.

At 24 months, about 50% of patients achieved a SALT score of 20, according to Melissa Piliang, MD, chair of Dermatology at the Cleveland Clinic, Cleveland, Ohio, who presented the data. In this group, as in the non-AT/AU population, responses climbed over time, and these responses have been maintained for as long as patients have remained on therapy.

At the more rigorous threshold of SALT < 10, the proportion of responders was only slightly lower, meaning a substantial proportion of patients with AT/AU “are achieving 90% or more of hair regrowth, so really an excellent response,” Dr. Piliang said.

For the subgroup with AU, specifically, regrowth of eyebrows and eyelashes was also observed in a substantial proportion, according to Dr. Piliang. Attributed to the often-devastating psychological burden of hair loss, patient-reported assessments of these responses global were generally “even better” than those reported by the investigators.

However, Dr. Piliang advised clinicians to treat AA as early as possible. Despite the benefits seen in the AT/AU subgroup, she pointed out that starting treatment before total hair loss is associated with a higher likelihood of complete or nearly complete hair regrowth.

There are no data from the ALLEGRO trial to determine how long hair regrowth persists after discontinuation of ritlecitinib, which has been approved for the treatment of AA, but Dr. Piliang said that patients should be told that lifelong therapy should be expected in the vast majority of individuals, whether or not AA has advanced to AT/AU.

“In my experience with JAK inhibitors, you lose response when you come off these drugs,” she said.

Dr. Meariman reported a financial relationship with AbbVie. Dr. Piliang reported financial relationships with Eli Lilly, Pfizer, and Proctor & Gamble. Dr. Armstrong reported financial relationships with more than 30 pharmaceutical companies, including those that manufacture JAK inhibitors. Dr. Guttman-Yassky reported financial relationships with more than 30 companies, including those that manufacture JAK inhibitors.

FROM AAD 2024

SAN DIEGO — In separate studies evaluating treatments for severe forms of alopecia, inhibitors of Janus kinases (JAKs) produced clinically meaningful hair regrowth, according to late-breaking data presented at the annual meeting of  the American Academy of Dermatology.

In one study of brepocitinib, the target was cicatricial alopecia (CA), a form of hair loss for which there are no approved therapies. In the other, a subanalysis from phase 3 trials of ritlecitinib for alopecia areata (AA), hair regrowth was shown in the subset of patients who entered the study with alopecia totalis or alopecia universalis (AT/AU).

Reflecting comments from several experts, including one of the late-breaking session moderators, April W. Armstrong, MD, MPH, professor and chief of dermatology, University of California, Los Angeles, said that the CA study, which matched clinical response to changes in CA biomarkers, suggested that the results are a potential breakthrough.

“This is the first placebo-controlled study with an oral JAK inhibitor that not only shows that scarring alopecia can be reversible but also gives insights to the mechanism of action and which patients might respond best,” Emma Guttman-Yassky, MD, PhD, said in an interview. Dr. Guttman-Yassky, professor of Dermatology and Immunology, and director of the Laboratory of Inflammatory Skin Diseases, Icahn School of Medicine at Mount Sinai, New York City, was the study’s senior investigator.

Scarring Alopecia and Brepocitinib

For the study of scarring alopecia, 49 patients with CA were randomized in a 3:1 ratio to brepocitinib, a first-in-class inhibitor that targets both JAK1 and TYK2, or placebo. Because of the small size of the study, the primary endpoint was the change in CA biomarkers. The secondary outcome was clinical response, but because of a correlation between the two, these were mutually reinforcing.

Of the subtypes, nine patients enrolled in the study had frontal fibrosing alopecia (FFA), 16 had lichen planopilaris (LPP) alopecia, and 24 had central centrifugal cicatricial alopecia (CCCA). All of the forms of CA are more common in women overall and women of color specifically, particularly CCCA. For this analysis, the FFA and LPP subtypes were considered similar for assessing response and were combined.

The data included a comparison of response and safety during the 24-week randomization phase, as well as an additional follow-up conducted after another 24 weeks of open-label treatment. During the second phase, all patients on placebo were switched to active treatment.

Overall, there was a reduction in all four of the key scalp inflammatory biomarkers measured among those in the combined FFA/LLP group. In the placebo group, each of these markers — interferon gamma (IFN-gamma), CCLS, CXCL10, and STAT1 — increased over the same time period. In almost all cases, the differences were statistically significant.

In the CCCA subgroup, the same pattern (an increase among those on placebo but a decrease among those on brepocitinib) was observed for CCLS and CXCL10. For IFN-gamma and STAT1, a rise was observed among those on placebo and those on active treatment, although the rise was greater for placebo.

For clinical response, improvement on brepocitinib was observed on disease activity indexes, particularly among those in the FFA/LLP group, according to Marguerite Meariman, MD, a dermatology resident at Mount Sinai, who presented the results. She called the improvement in clinical activity scores at 48 weeks “dramatic.” Moreover, improvement was apparent within 4 weeks of starting therapy.

For CCCA, a more challenging condition to treat, Dr. Meariman said that no further progression might represent an acceptable response for many patients, but there were also cases of hair regrowth in this subset. Although improvement was not generally on the order seen among those with FFA/LLP, she suggested that there is promise even in these more difficult patients.

Further studies are planned, but Dr. Meariman said that it might be important to focus on early treatment regardless of CA subtype. She noted that patients with less than 5 years disease duration typically did better than those with longer durations.

Hand, foot, and mouth disease (HFMD) is a viral infection that commonly affects children under the age of five. It is primarily caused by coxsackieviruses and other enterovirus species.¹ While it predominantly affects children, it is important to note that it can also affect adults. Although it is not a life threatening infection, it can cause a painful rash and is highly contagious. The infection is easily spread in multiple ways, including via respiratory droplets, contact with vesicular or nasal secretions, or through fecal-oral transmission. Most cases occur during the summer and fall seasons but individuals can be infected at any time of the year.

HFMD typically starts with a few days of non-specific viral symptoms, such as fever, cough, sore throat, and fatigue. It is then followed by an eruption of intraoral macules and vesicles and a widespread distribution of oval shaped macules that predominantly involve the hands and feet.¹ Both children and adults can present atypically. Atypical presentations include vesicles and bullae on extensor surfaces such as the forearms, as well as eruptions on the face or buttocks.² Other atypical morphologies include eczema herpeticum-like, Gianotti-Crosti-like, and purpuric/petechiae.³ Atypical hand, food, and mouth disease cases are often caused by coxsackievirus A6, however other strains of coxsackievirus can also cause atypical symptoms.^2,3

Our 35-year-old female patient presented with eroded papules and vesicles around the mouth. A diagnosis of atypical HFMD was made clinically in the following days when the patient developed the more classic intraoral and acral macules and vesicles.

Rosemary (Salvia rosmarinus, formerly Rosmarinus officinalis) has been a common ingredient in cosmetic and cosmeceutical products for the last few decades. Used as a spice in various, particularly Mediterranean, cuisines and in traditional medicine for hundreds of years, this aromatic shrub has been the focus of substantial research this century to clarify its roles in skin care. It is used broadly in cosmetic formulations, particularly to preserve the product, and acts as a skin conditioner and fragrance in safe concentrations.¹ Rosemary essential oil is also a popular choice frequently used in aromatherapy.^2,3 This column focuses on recent promising results supporting the antioxidant and anti-photoaging activities, especially, of rosemary.

UV Protection and Rosemary in Combination

A 2021 study in mice authored by Auh and Madhavan showed that a mixture of marigold and rosemary extracts yielded anti-photoaging effects, with the botanical formula suppressing UV-induced damage.⁴

Seven years earlier, Pérez-Sánchez et al. combined rosemary and citrus extracts and found that they exerted protective effects against UV damage in human HaCaT keratinocytes as well as human volunteers after oral consumption. Significant increases in minimal erythema dose (MED) were seen in participants, with daily intake of 250 mg of botanical combination, at 8 weeks (34%) and 12 weeks (56%). The investigators attributed the photoprotective effects of the formula to rosemary polyphenols and diterpenes as well as citrus flavonoids.⁵

Evaluation of a human skin cell model by Sánchez-Marzo et al. in 2020 revealed that rosemary diterpenes were instrumental in an herbal extract that combined citrus, olive, and rosemary in conferring genoprotection against UV-induced DNA damage. The authors note that human trials are needed to overcome the limitations of the cellular model in ascertaining whether the tested herbal formulations can yield oral and/or topical photoprotection.⁶

Anti-Photoaging and Anti-Pollution

In 2022, Ibrahim et al. assessed a hexane extract of rosemary leaves for anti-photoaging activity. Their evaluation showed an abundance of triterpenoids, monoterpenoids, and phenolic diterpenes in rosemary, with in vitro assays verifying the anti-aging, antioxidant, and wound healing functions of the extract. Further, topical rosemary hexane extract–loaded lipid nanocapsules protected rat skin from UV radiation, as epidermal and dermal histological parameters improved, antioxidant biochemical balance was restored, and inflammatory markers and wrinkling were diminished. The researchers concluded that the use of rosemary hexane extract represents a safe, efficient, and cost-effective way to deliver anti-aging, photoprotective functions to cosmeceutical formulations.⁷

In March 2021, Nobile et al. published a report on their randomized, double-blind, placebo-controlled parallel group study to investigate the efficacy of a marketed polyphenol-enriched dietary supplement (Zeropollution, which contains four standardized herbal extracts: Olea europaea leaf, Lippia citriodora, S. rosmarinus, and Sophora japonica) in diminishing pollution-induced oxidative stress and in improving skin aging in 100 White and Asian women who were outdoor workers living in a polluted environment (Milan, Italy). Statistically significant improvements in reducing wrinkle depth and hyperpigmentation, enhancing elasticity and firmness, as well as promoting skin moisturization and diminishing transepidermal water loss were noted as early as 2 weeks after product consumption began, with inter-group and intra-group analysis verifying that all skin parameters were ameliorated in Asian and White subjects.⁸

Previously, Nobile et al. conducted a randomized, parallel-group study on 90 subjects to evaluate the photoprotective effects of a combination of rosemary and grapefruit (Citrus paradisi) extracts (Nutroxsun). The investigators also performed a pilot, randomized crossover study on five participants. Both studies included only females with Fitzpatrick skin phototypes I-III who manifested mild to moderate chronological aging or photoaging. Within as little as 2 weeks, treated individuals exhibited reductions in UVA- and UVB-induced skin changes. Skin elasticity improved in this group, with wrinkles diminishing along with skin redness and lipoperoxides. The investigators concluded that the oral blend of rosemary and grapefruit consumed long term merits consideration as an adjuvant approach to preventing the deleterious effects of solar exposure.⁹

In 2021, Hoskin et al. used ex vivo human biopsies exposed to diesel engine exhaust to study the impact of spray-dried algae-rosemary particles against pollution-induced damage. The spirulina-rosemary gel that was developed lowered levels of 4-hydroxynonenal protein adducts (4HNE-PA) as well as matrix metalloproteinase-9 (MMP-9) and reduced the loss of filaggrin. The researchers concluded that their topically applied spirulina-rosemary gel was effective in mitigating or preventing skin aging and cutaneous damage caused by diesel air pollution.¹⁰

Antioxidant, Antibacterial, and Anti-Inflammatory Activity

Based on a 2023 literature search by Li Pomi et al. of in vitro as well as in vivo animal and human studies involving S. rosmarinus and the skin, researchers reported on substantial evidence buttressing the antioxidant role of the botanical agent. They cautioned that, while data support the harnessing of the bioactive constituents of rosemary to address inflammatory and infectious skin conditions, large controlled trials remain necessary to establish its potential functions in dermatologic clinical practice.¹¹

Baumann Cosmetic &amp; Research Institute

Ten years earlier, Park et al. determined that a phenolic diterpene from rosemary (carnosic acid) prevented UV-induced expression of MMP-1, MMP-3, and MMP-9 in human skin fibroblasts and keratinocytes in a concentration-dependent manner by suppressing reactive oxygen species and blocking through the inhibition of ROS and the suppression of extracellular signal-regulated kinase (ERK)-mediated AP-1 activation.¹²

Around the same time, Sienkiewicz et al. showed that rosemary essential oil exhibits antibacterial activity against the standard strain Escherichia coli ATCC 25922 and 60 other clinical strains of the bacteria.¹³

Further, anti-inflammatory properties have been attributed to rosemary essential oil, which are thought to be due to its suppression of nuclear factor kappa B transcription and inhibition of the arachidonic acid cascade.¹⁴

Other Functions of Rosemary

In 2022, Sutkowska-Skolimowska et al. demonstrated that rosemary extract in concentrations of 50 and 100mcg/mL significantly diminished accumulated collagen in the fibroblasts of four patients with severe and fatal osteogenesis imperfecta, suggesting that the botanical agent may have a role targeting cellular stress and inducing autophagy in therapy for this condition.¹⁵

In 2015, Akbari et al. established that 0.5% and 1% concentrations of rosemary essential oil were effective in facilitating the percutaneous absorption of diclofenac sodium topical gel.¹⁶

Conclusion

In Western culture, rosemary is thought of more as a spice to add flavor to food. However, there appears to be an emerging body of evidence suggesting various possible functions for rosemary in the dermatologic armamentarium. Much more research is necessary, though, to ascertain the most appropriate and optimal roles for this popular herb in skin care.

Rosemary (Salvia rosmarinus, formerly Rosmarinus officinalis) has been a common ingredient in cosmetic and cosmeceutical products for the last few decades. Used as a spice in various, particularly Mediterranean, cuisines and in traditional medicine for hundreds of years, this aromatic shrub has been the focus of substantial research this century to clarify its roles in skin care. It is used broadly in cosmetic formulations, particularly to preserve the product, and acts as a skin conditioner and fragrance in safe concentrations.¹ Rosemary essential oil is also a popular choice frequently used in aromatherapy.^2,3 This column focuses on recent promising results supporting the antioxidant and anti-photoaging activities, especially, of rosemary.

UV Protection and Rosemary in Combination

A 2021 study in mice authored by Auh and Madhavan showed that a mixture of marigold and rosemary extracts yielded anti-photoaging effects, with the botanical formula suppressing UV-induced damage.⁴

Seven years earlier, Pérez-Sánchez et al. combined rosemary and citrus extracts and found that they exerted protective effects against UV damage in human HaCaT keratinocytes as well as human volunteers after oral consumption. Significant increases in minimal erythema dose (MED) were seen in participants, with daily intake of 250 mg of botanical combination, at 8 weeks (34%) and 12 weeks (56%). The investigators attributed the photoprotective effects of the formula to rosemary polyphenols and diterpenes as well as citrus flavonoids.⁵

Evaluation of a human skin cell model by Sánchez-Marzo et al. in 2020 revealed that rosemary diterpenes were instrumental in an herbal extract that combined citrus, olive, and rosemary in conferring genoprotection against UV-induced DNA damage. The authors note that human trials are needed to overcome the limitations of the cellular model in ascertaining whether the tested herbal formulations can yield oral and/or topical photoprotection.⁶

Anti-Photoaging and Anti-Pollution

In 2022, Ibrahim et al. assessed a hexane extract of rosemary leaves for anti-photoaging activity. Their evaluation showed an abundance of triterpenoids, monoterpenoids, and phenolic diterpenes in rosemary, with in vitro assays verifying the anti-aging, antioxidant, and wound healing functions of the extract. Further, topical rosemary hexane extract–loaded lipid nanocapsules protected rat skin from UV radiation, as epidermal and dermal histological parameters improved, antioxidant biochemical balance was restored, and inflammatory markers and wrinkling were diminished. The researchers concluded that the use of rosemary hexane extract represents a safe, efficient, and cost-effective way to deliver anti-aging, photoprotective functions to cosmeceutical formulations.⁷

In March 2021, Nobile et al. published a report on their randomized, double-blind, placebo-controlled parallel group study to investigate the efficacy of a marketed polyphenol-enriched dietary supplement (Zeropollution, which contains four standardized herbal extracts: Olea europaea leaf, Lippia citriodora, S. rosmarinus, and Sophora japonica) in diminishing pollution-induced oxidative stress and in improving skin aging in 100 White and Asian women who were outdoor workers living in a polluted environment (Milan, Italy). Statistically significant improvements in reducing wrinkle depth and hyperpigmentation, enhancing elasticity and firmness, as well as promoting skin moisturization and diminishing transepidermal water loss were noted as early as 2 weeks after product consumption began, with inter-group and intra-group analysis verifying that all skin parameters were ameliorated in Asian and White subjects.⁸

Previously, Nobile et al. conducted a randomized, parallel-group study on 90 subjects to evaluate the photoprotective effects of a combination of rosemary and grapefruit (Citrus paradisi) extracts (Nutroxsun). The investigators also performed a pilot, randomized crossover study on five participants. Both studies included only females with Fitzpatrick skin phototypes I-III who manifested mild to moderate chronological aging or photoaging. Within as little as 2 weeks, treated individuals exhibited reductions in UVA- and UVB-induced skin changes. Skin elasticity improved in this group, with wrinkles diminishing along with skin redness and lipoperoxides. The investigators concluded that the oral blend of rosemary and grapefruit consumed long term merits consideration as an adjuvant approach to preventing the deleterious effects of solar exposure.⁹

In 2021, Hoskin et al. used ex vivo human biopsies exposed to diesel engine exhaust to study the impact of spray-dried algae-rosemary particles against pollution-induced damage. The spirulina-rosemary gel that was developed lowered levels of 4-hydroxynonenal protein adducts (4HNE-PA) as well as matrix metalloproteinase-9 (MMP-9) and reduced the loss of filaggrin. The researchers concluded that their topically applied spirulina-rosemary gel was effective in mitigating or preventing skin aging and cutaneous damage caused by diesel air pollution.¹⁰

Antioxidant, Antibacterial, and Anti-Inflammatory Activity

Based on a 2023 literature search by Li Pomi et al. of in vitro as well as in vivo animal and human studies involving S. rosmarinus and the skin, researchers reported on substantial evidence buttressing the antioxidant role of the botanical agent. They cautioned that, while data support the harnessing of the bioactive constituents of rosemary to address inflammatory and infectious skin conditions, large controlled trials remain necessary to establish its potential functions in dermatologic clinical practice.¹¹

Baumann Cosmetic &amp; Research Institute

Ten years earlier, Park et al. determined that a phenolic diterpene from rosemary (carnosic acid) prevented UV-induced expression of MMP-1, MMP-3, and MMP-9 in human skin fibroblasts and keratinocytes in a concentration-dependent manner by suppressing reactive oxygen species and blocking through the inhibition of ROS and the suppression of extracellular signal-regulated kinase (ERK)-mediated AP-1 activation.¹²

Around the same time, Sienkiewicz et al. showed that rosemary essential oil exhibits antibacterial activity against the standard strain Escherichia coli ATCC 25922 and 60 other clinical strains of the bacteria.¹³

Further, anti-inflammatory properties have been attributed to rosemary essential oil, which are thought to be due to its suppression of nuclear factor kappa B transcription and inhibition of the arachidonic acid cascade.¹⁴

Other Functions of Rosemary

In 2022, Sutkowska-Skolimowska et al. demonstrated that rosemary extract in concentrations of 50 and 100mcg/mL significantly diminished accumulated collagen in the fibroblasts of four patients with severe and fatal osteogenesis imperfecta, suggesting that the botanical agent may have a role targeting cellular stress and inducing autophagy in therapy for this condition.¹⁵

In 2015, Akbari et al. established that 0.5% and 1% concentrations of rosemary essential oil were effective in facilitating the percutaneous absorption of diclofenac sodium topical gel.¹⁶

Conclusion

In Western culture, rosemary is thought of more as a spice to add flavor to food. However, there appears to be an emerging body of evidence suggesting various possible functions for rosemary in the dermatologic armamentarium. Much more research is necessary, though, to ascertain the most appropriate and optimal roles for this popular herb in skin care.

President Joe Biden on March 9 signed into law a measure that softened — but did not completely eliminate — a 2024 cut in a key rate used to determine how physicians are paid for treating Medicare patients.

While physician groups hailed the move as partial relief, they say they’ll continue to press for broader changes in the Medicare physician fee schedule.

The Medicare provision was tucked into a larger spending package approved by the US House and Senate.

The American Academy of Family Physicians (AAFP), the American Medical Association (AMA), and other groups have lobbied Congress for months to undo a 3.4% cut in the base rate, or conversion factor, in the physician fee schedule for 2024.

The conversion factor is used in calculations to determine reimbursement for myriad other services. Federal Medicare officials said the cut would mean a 1.25% decrease in overall payments in 2024, compared with 2023.

“With the passage of this legislation, Congress has offset 2.93% of that payment cut,” said Steven P. Furr, MD, AAFP’s president in a statement. “We appreciate this temporary measure but continue to urge Congress to advance comprehensive, long-term Medicare payment reform.”

In a statement, Representative Larry Bucshon, MD (R-IN), said the payment cut could not be completely eliminated because of budget constraints.

The Medicare physician fee schedule covers much of the care clinicians provide to people older than 65 and those with disabilities. It covers about 8000 different types of services, ranging from office visits to surgical procedures, imaging, and tests, according to the Medicare Payment Advisory Commission (MedPAC).

Along with physicians, the fee schedule sets payments for nurse practitioners, physician assistants, podiatrists, physical therapists, psychologists, and other clinicians.

In 2021, the Medicare program and its beneficiaries paid $92.8 billion for services provided by almost 1.3 million clinicians, MedPAC said.
 

Larger Changes Ahead?

Rep. Bucshon is among the physicians serving in the House who are pressing for a permanent revamp of the Medicare physician fee schedule. He cosponsored a bill (HR 2474) that would peg future annual increases in the physician fee schedule to the Medicare Economic Index, which would reflect inflation’s effect.

In April, more than 120 state and national medical groups signed onto an AMA-led letter urging Congress to pass this bill.

The measure is a key priority for the AMA. The organization reached out repeatedly last year to federal officials about it through its own in-house lobbyists, this news organization found through a review of congressional lobbying forms submitted by AMA.

These required disclosure forms reveal how much AMA and other organizations spend each quarter to appeal to members of Congress and federal agencies on specific issues. The disclosure forms do not include a detailed accounting of spending on each issue.

But they do show which issues are priorities for an organization. AMA’s in-house lobbyists reported raising dozens of issues in 2024 within contacts in Congress and federal agencies. These issues included abortion access, maternal health, physician burnout, and potential for bias in clinical use of algorithms, as well as Medicare payment for physicians.

AMA reported spending estimated cost of $20.6 million. (AMA spent $6.7 million in the first quarter, $4.75 million in the second quarter, $3.42 million in the third quarter, and $5.74 million in the fourth quarter.)

In a March 6 statement, Jesse M. Ehrenfeld, MD, MPH, AMA president, urged Congress to turn to more serious consideration of Medicare physician pay beyond short-term tweaks attached to other larger bills.

“As physicians, we are trained to run toward emergencies. We urge Congress to do the same,” Dr. Ehrenfeld said. “We encourage Congress to act if this policy decision is an emergency because — in fact — it is. It is well past time to put an end to stopgap measures that fail to address the underlying causes of the continuing decline in Medicare physician payments.”

There’s bipartisan interest in a revamp of the physician fee schedule amid widespread criticism of the last such overhaul, the Medicare Access and CHIP Reauthorization Act of 2015.

For example, Senate Budget Chairman Sheldon Whitehouse (D-RI) has proposed the creation of a technical advisory committee to improve how Medicare sets the physician fee schedule. The existing fee schedule provides too little money for primary care services and primary care provider pay, contributing to shortages, Sen. Whitehouse said.

Sen. Whitehouse on March 6 held a hearing on ways to beef up US primary care. Among the experts who appeared was Amol Navathe, MD, PhD, of the University of Pennsylvania, Philadelphia, Pennsylvania.

Dr. Navathe said the current Medicare physician fee schedule tilts in favor of procedural services, leading to “underinvestment in cognitive, diagnostic, and supportive services such as primary care.”

In addition, much of what primary care clinicians do, “such as addressing social challenges, is not included in the codes of the fee schedule itself,” said Dr. Navathe, who also serves as the vice chairman of MedPAC.

It’s unclear when Congress will attempt a serious revision to the Medicare physician fee schedule. Lawmakers are unlikely to take on such a major challenge in this election year.

There would be significant opposition and challenges for lawmakers in trying to clear a bill that added an inflation adjustment for what’s already seen as an imperfect physician fee schedule, said Mark E. Miller, PhD, executive vice president of healthcare at the philanthropy Arnold Ventures, which studies how payment decisions affect medical care.

“That bill could cost a lot of money and raise a lot of questions,” Dr. Miller said.

TOPLINE:

Topical calcineurin inhibitors (TCIs), topical corticosteroids (TCSs), and topical Janus kinase (JAK) inhibitors are supported as mainstay treatments in new expert recommendations on the use of topical therapeutics in children, adolescents, and young adults with vitiligo.

METHODOLOGY:

• While half of all vitiligo cases manifest within the initial two decades of life, no guidelines specifically address the management of vitiligo in children, adolescents, and young adults with vitiligo.
• A protocol was established to formulate consensus recommendations addressing questions related to pediatric vitiligo.
• Overall, 50 articles on topical corticosteroids and/or topical calcineurin inhibitors, five on topical Janus kinase inhibitors, and two each on pseudocatalase and microdermabrasion were included.
• The participants recorded their agreement levels with the formulated statements, using a 5-point Likert scale.

TAKEAWAY:

• TCIs, TCSs, JAK inhibitors, and phototherapy, specifically narrowband ultraviolet (UV)-B light therapy, are mainstay treatments; the combination of UV-B light and topical therapy may enhance initial repigmentation.
• Long-term monitoring for skin cancers is advised, and short outdoor UV exposure is suggested for pediatric patients.
• TCIs, such as tacrolimus and pimecrolimus, are recommended as first-line therapy, particularly on the face, applied twice daily for ≥ 3 months; continued use for 6-12 additional months is recommended if repigmentation is observed.
• The choice of TCS class depends on the site and planned usage duration. Short-term use or overlap with TCIs is recommended because of the risk for atrophy with long-term TCS use. Class 5-6 agents are another option.
• For areas with thin skin, TCSs can be considered second-line treatments.
• Topical JAK inhibitors, specifically topical 1.5% ruxolitinib cream, are recommended for patients aged ≥ 12 years, as first- or second-line therapy. Limitation to 10% body surface area is recommended to minimize systemic absorption. Limited evidence exists for children aged < 12 years.

IN PRACTICE:

“Effective therapy requires a focus on long-term therapeutic interventions to maximize the local gain and retention of pigmentation with a trial period of twice-weekly application. Counseling should include discussion of the chronicity of vitiligo and the need for long-term care,” the authors wrote.

LIMITATIONS:

Some of the recommendations were opinion-based because of the scarcity of evidence-based literature.

SOURCE:

The consensus statement was published on March 13 in JAMA Dermatology.

DISCLOSURES:

This work was supported by grants from Vitiligo Research Foundation and Incyte Pharmaceuticals. The majority of authors disclosed financial relationships outside this work; several reported no disclosures.

• TCIs, TCSs, JAK inhibitors, and phototherapy, specifically narrowband ultraviolet (UV)-B light therapy, are mainstay treatments; the combination of UV-B light and topical therapy may enhance initial repigmentation.
• Long-term monitoring for skin cancers is advised, and short outdoor UV exposure is suggested for pediatric patients.
• TCIs, such as tacrolimus and pimecrolimus, are recommended as first-line therapy, particularly on the face, applied twice daily for ≥ 3 months; continued use for 6-12 additional months is recommended if repigmentation is observed.
• The choice of TCS class depends on the site and planned usage duration. Short-term use or overlap with TCIs is recommended because of the risk for atrophy with long-term TCS use. Class 5-6 agents are another option.
• For areas with thin skin, TCSs can be considered second-line treatments.
• Topical JAK inhibitors, specifically topical 1.5% ruxolitinib cream, are recommended for patients aged ≥ 12 years, as first- or second-line therapy. Limitation to 10% body surface area is recommended to minimize systemic absorption. Limited evidence exists for children aged < 12 years.

IN PRACTICE:

“Effective therapy requires a focus on long-term therapeutic interventions to maximize the local gain and retention of pigmentation with a trial period of twice-weekly application. Counseling should include discussion of the chronicity of vitiligo and the need for long-term care,” the authors wrote.

LIMITATIONS:

Some of the recommendations were opinion-based because of the scarcity of evidence-based literature.

Sublingual immunotherapy (SLIT) is as safe and effective for high-risk older children and adolescents as oral immunotherapy (OIT) is for infants and preschoolers, according to new research.

Preliminary data from a study of more than 180 pediatric patients with multiple food allergies showed that while most patients had mild symptoms, none experienced a severe grade 4 reaction during the buildup and maintenance phase of SLIT.

In addition, 70% of those tested at the end of the treatment protocol were able to tolerate 300 mg of their allergen, a success rate nearly as high as that for OIT.

The study was published in The Journal of Allergy and Clinical Immunology: In Practice.

SLIT has been used successfully in the treatment of environmental allergens such as grass and tree pollen and dust mites. In this study, researchers decided to test SLIT’s effectiveness and safety in the treatment of food allergies in older children.

“We knew that OIT is very effective and safe in infants and toddlers, but there was literature illustrating that for older, school-age kids and adolescents, OIT is not safe enough, as those older age groups tend to have higher risk of severe reaction during treatment,” senior author Edmond Chan, MD, clinical professor of allergy at the University of British Columbia and pediatric allergist at BC Children’s Hospital, both in Vancouver, British Columbia, Canada, told this news organization. “With that knowledge, we decided to explore SLIT as another first-phase therapy for the older kids.”

The investigators recruited 188 high-risk older children aged 4-18 years for multifood SLIT. Most (61.7%) participants had multiple food allergies. Approximately 68% were male, and the population’s median age was 11.3 years.

Nearly half (48.4%) of participants had atopic dermatitis, 45.2% had asthma, 58.0% had allergic rhinitis, and 2.66% had preexisting eosinophilic esophagitis.

Most (75.0%) of the children were classified as higher risk, and 23 had a history of a grade 3 or 4 reaction before beginning SLIT.

Of the 188 children who were initially enrolled in the study, 173 (92.0%) finished their SLIT buildup phase.

Because the study started when COVID-19 pandemic restrictions were in place, the SLIT protocol mandated that patients be seen virtually. The patients’ caregivers learned how to mix and administer the required doses at home using recipes specially developed by the research team that used products bought at the grocery store.

A wide variety of food allergens were treated, including peanut, other legumes, tree nuts, sesame, other seeds, egg, cow’s milk, fish, wheat, shrimp, and other allergens.

The children built up to 2-mg protein SLIT maintenance over the course of three to five visits under nurse supervision.

After 1-2 years of daily SLIT maintenance, patients were offered a low-dose oral food challenge (OFC; cumulative dose: 300 mg of protein) with the goal of bypassing OIT buildup.

Nearly all patients (93.1%) had symptoms during SLIT buildup, but most were mild grade 1 (52.1%) or 2 (40.4%) reactions. Only one patient had a grade 3 reaction. None of the patients experienced a severe grade 4 reaction.

The most common grade 1 reaction was oral itch, an expected symptom of SLIT, which occurred in 82.7% of the patients.

Four patients (2.10%) received epinephrine during buildup and went to the emergency department. All these patients returned to continue SLIT without further need for epinephrine.

To test the effectiveness of SLIT, the researchers performed 50 low-dose OFCs in 20 patients. Of these food challenges, 35 (70%) were successful, and patients were asked to start daily 300-mg OIT maintenance, thus bypassing OIT buildup.

An additional nine OFCs that were unsuccessful were counseled to self-escalate from 80 mg or higher to 300 mg at home with medical guidance as needed.

“Our preliminary data of 20 patients and 50 low-dose oral food challenges suggest that an initial phase of 1-2 years of 2-mg daily SLIT therapy may be a safe and effective way to bypass the OIT buildup phase without the need for dozens of in-person visits with an allergist,” said Dr. Chan.

“So now we have the best of both worlds. We harness the safety of SLIT for the first 1-2 years, with the effectiveness of OIT for the remainder of the treatment period,” he said.
 

Adds to Evidence

Commenting on the study for this news organization, Julia Upton, MD, associate professor of pediatrics at the University of Toronto, Toronto, Ontario, Canada, said, “This study adds to the evidence that consistent, low exposure to food drives meaningful desensitization far above the daily dose.” Upton did not participate in the research.

“Prior prospective studies in SLIT demonstrated that small single-digit-milligram doses and time greatly increased the threshold of reaction. This real-world report suggests that a way to utilize that threshold increase is by switching to a commonly used maintenance dose of OIT,” said Dr. Upton.

“Although few patients have been assessed for the 300-mg challenge, this study is notable for the age group of 4-18 years, and that many of the patients had reacted to low doses in the past. It also shows that many families are capable of diluting and mixing their own immunotherapy solutions with store-bought foods under the guidance of an experienced allergy clinic,” she added.

“Overall, evidence is building that by various routes, initial small amounts with minimal updoses, plus the tincture of time, may be preferred to multiple frequent updosing from multiple perspectives, including safety, feasibility, cost, and medical resources. It will also be important to understand the preferences and goals of the patient and family as various regimens become more available,” Dr. Upton concluded.

The study was funded by BC Children’s Hospital Foundation. Dr. Chan reported receiving research support from DVB Technologies; has been a member of advisory boards for Pfizer, Miravo, Medexus, Leo Pharma, Kaleo, DBV, AllerGenis, Sanofi, Genzyme, Bausch Health, Avir Pharma, AstraZeneca, ALK, and Alladapt; and was a colead of the CSACI OIT guidelines. Dr. Upton reported research support/grants from Novartis, Regeneron, Sanofi, ALK Abello, DBV Technologies, CIHR, and SickKids Food Allergy and Anaphylaxis Program and fees from Pfizer, ALK Abello, Bausch Health, Astra Zeneca, and Pharming.

SAN DIEGO — Just weeks after the American Academy of Dermatology (AAD) published its updated acne management guidelines, a dermatologist who helped write the recommendations provided colleagues with insight into recently approved topical therapies, the importance of multimodal therapy, and a controversial report linking benzoyl peroxide (BP) to the carcinogen benzene.

In regard to topical treatments, the guidelines make a “strong” recommendation for topical retinoids based on “moderate” evidence, Andrea L. Zaenglein, MD, professor of dermatology and pediatrics, Penn State University, Hershey, Pennsylvania, said at the annual meeting of the American Academy of Dermatology. The recommendation was based on a pooled analysis of four randomized controlled trials that found patients with acne who used the medications were more likely to have improvement via the Investigator Global Assessment (IGA) scale at 12 weeks than were those treated with a vehicle (risk ratio [RR], 1.57; 1.21-2.04).

The updated guidelines were published on January 30 in the Journal of the American Academy of Dermatology. The previous guidelines were issued in 2016.

“We have four current retinoids that we use: adapalene, tretinoin, tazarotene, and trifarotene,” Dr. Zaenglein said. “Typically, when we think about retinoids, we think of adapalene as being more tolerable and tazarotene as being more effective. But we also know that they can work to prevent and treat scarring, and they work against comedonal lesions and inflammatory lesions.”

Newer concentrations include tretinoin 0.05% lotion, tazarotene 0.045% lotion, and trifarotene 0.005% cream. She noted that this trifarotene concentration can be helpful for moderate truncal acne and also referred to evidence that whey protein appears to exacerbate that condition. “I always ask teenage kids about that: Are they using those protein powders?”
 

Recommendations for ‘Multimodal Therapy,’ Especially With Antibiotics

Dr. Zaenglein highlighted a “good practice statement” in the new guidelines that says, “when managing acne with topical medications, we recommend multimodal therapy combining multiple mechanisms of action.”

Topical antibiotics are effective treatments on their own and include erythromycin, clindamycin, and minocycline (Minocin), she said. But the guidelines, which refer to evidence supporting them as “moderate,” do not recommend them as monotherapy because of the risk for antibiotic resistance.

The oral retinoid isotretinoin may be appropriate in conjunction with topical medications, she said, “and we also recommend fixed combination products because they’re associated with increased adherence.”

Dermatologists are familiar with several of these products because “we’ve been using them for years and years,” she said. The guidelines note that “compared to vehicle at 12 weeks, a greater proportion of patients treated with combined BP and topical retinoid achieved IGA success in three RCTs (RR, 2.19; 1.77-2.72).”

Dr. Zaenglein noted that the guidelines recommend that patients taking antibiotics also use benzoyl peroxide, which has “moderate” evidence regarding preventing the development of antibiotic resistance. “Lower strengths tend to be less irritating, and over-the-counter formulations are readily available,” she said, adding that colleagues should make sure to warn patients about the risk of bleaching clothes and towels with BP.

Now, there’s a newly approved treatment, the first fixed-dose triple combination therapy for acne, she said. It combines 1.2% clindamycin, 3.1% benzoyl peroxide, and 0.15% adapalene (Cabtreo) and is Food and Drug Administration (FDA)-approved for treating acne in patients ages 12 and up.

The new AAD guidelines note that “potential adverse effect profiles of the fixed-dose combinations generally reflect those of the individual agents in summation. Some fixed-dose combination products may be less expensive than prescribing their individual components separately.” The evidence supporting fixed-dose combinations in conjunction with benzoyl peroxide is considered “moderate.”

Dapsone gel, 7.5% (Aczone) is another option for acne. “It’s a topical so you don’t need to do G6PD [glucose-6-phosphate dehydrogenase] testing,” Dr. Zaenglein said. “It’s well tolerated, and mean total lesions fell by 48.9% vs 43.2% for vehicle,” in a 2018 study, which she said also found that females benefited more than males from this treatment.

Clascoterone 1% cream (Winlevi), approved in 2020, is appropriate for males and females aged 12 and up, Dr. Zaenglein said. She noted that it’s the only topical anti-androgen that can be used in males. However, while it has a “high” level of evidence because of phase 3 clinical trials showing benefits in moderate to severe acne, the AAD guidelines only conditionally recommend this option because the high price of clascoterone “may impact equitable acne treatment access.” The price listed on the website GoodRx (accessed on March 12) lists drugstore prices for a single 60-gram tube as ranging from $590 to $671.

“One of the harder things is trying to figure out where clascoterone fits in our kind of standard combination therapy,” she said. “Much like other hormonal therapies, it works better over the long term.”

Two more topical options per the AAD guidelines are salicylic acid, based on one randomized controlled trial, and azelaic acid (Azelex, Finacea), based on three randomized controlled trials. Both of these recommendations are conditional because of limited evidence: Evidence is considered “low” for salicylic acid and “moderate” for azelaic acid, the guidelines say, and azelaic acid “may be particularly helpful for patients with sensitive skin or darker skin types due to its lightening effect on dyspigmentation.”

As for risk for topical treatments during pregnancy/lactation, the guidelines note that topical therapies other than topical retinoids are “preferred” during pregnancy. Tazarotene is contraindicated during pregnancy, and salicylic acid should be used only in limited areas of exposure. There are no data for dapsone and clascoterone during pregnancy/lactation, and minocycline is “not recommended.”

The guideline authors noted that “available evidence is insufficient to develop a recommendation on the use of topical glycolic acid, sulfur, sodium sulfacetamide, and resorcinol for acne treatment or to make recommendations that compare topical BP, retinoids, antibiotics, and their combinations directly against each other.”
 

Could BP Post a Risk From Benzene?

Dr. Zaenglein highlighted a recently released report by Valisure, an independent laboratory, which reported finding high levels of the cancer-causing chemical benzene in several acne treatments, including brands such as Clearasil. “They didn’t release all of the ones that they evaluated, but there were a lot ... that we commonly recommend for our patients,” she said.

On March 6, CBS News reported that Valisure “ran tests at various temperatures over 18 days and found some products ‘can form over 800 times the conditionally restricted FDA concentration limit of two parts per million (ppm) for benzene’ in 2 weeks at 50° C (122° F),” but that benzene levels “at room temperature were more modest, ranging from about one to 24 parts per million.”

Dr. Zaenglein said she’s not ready to urge patients to discontinue BP, although in light of the findings, “I will tell them to store it at room temperature or lower.”

For now, it’s important to wait for independent verification of the results, she said. “And then it’s up to the manufacturers to reevaluate the stability of their benzoyl peroxide products with heat.”

Dr. Zaenglein disclosed relationships with AbbVie, Arcutis, Biofrontera, Galderma, and Incyte (grants/research funding), Church & Dwight (consulting fees), and UCB (consulting honoraria).

“One of the harder things is trying to figure out where clascoterone fits in our kind of standard combination therapy,” she said. “Much like other hormonal therapies, it works better over the long term.”

Two more topical options per the AAD guidelines are salicylic acid, based on one randomized controlled trial, and azelaic acid (Azelex, Finacea), based on three randomized controlled trials. Both of these recommendations are conditional because of limited evidence: Evidence is considered “low” for salicylic acid and “moderate” for azelaic acid, the guidelines say, and azelaic acid “may be particularly helpful for patients with sensitive skin or darker skin types due to its lightening effect on dyspigmentation.”

As for risk for topical treatments during pregnancy/lactation, the guidelines note that topical therapies other than topical retinoids are “preferred” during pregnancy. Tazarotene is contraindicated during pregnancy, and salicylic acid should be used only in limited areas of exposure. There are no data for dapsone and clascoterone during pregnancy/lactation, and minocycline is “not recommended.”

The guideline authors noted that “available evidence is insufficient to develop a recommendation on the use of topical glycolic acid, sulfur, sodium sulfacetamide, and resorcinol for acne treatment or to make recommendations that compare topical BP, retinoids, antibiotics, and their combinations directly against each other.”
 

Could BP Post a Risk From Benzene?

Dr. Zaenglein highlighted a recently released report by Valisure, an independent laboratory, which reported finding high levels of the cancer-causing chemical benzene in several acne treatments, including brands such as Clearasil. “They didn’t release all of the ones that they evaluated, but there were a lot ... that we commonly recommend for our patients,” she said.

On March 6, CBS News reported that Valisure “ran tests at various temperatures over 18 days and found some products ‘can form over 800 times the conditionally restricted FDA concentration limit of two parts per million (ppm) for benzene’ in 2 weeks at 50° C (122° F),” but that benzene levels “at room temperature were more modest, ranging from about one to 24 parts per million.”

Dr. Zaenglein said she’s not ready to urge patients to discontinue BP, although in light of the findings, “I will tell them to store it at room temperature or lower.”

For now, it’s important to wait for independent verification of the results, she said. “And then it’s up to the manufacturers to reevaluate the stability of their benzoyl peroxide products with heat.”

Dr. Zaenglein disclosed relationships with AbbVie, Arcutis, Biofrontera, Galderma, and Incyte (grants/research funding), Church & Dwight (consulting fees), and UCB (consulting honoraria).

SAN DIEGO — Just weeks after the American Academy of Dermatology (AAD) published its updated acne management guidelines, a dermatologist who helped write the recommendations provided colleagues with insight into recently approved topical therapies, the importance of multimodal therapy, and a controversial report linking benzoyl peroxide (BP) to the carcinogen benzene.

In regard to topical treatments, the guidelines make a “strong” recommendation for topical retinoids based on “moderate” evidence, Andrea L. Zaenglein, MD, professor of dermatology and pediatrics, Penn State University, Hershey, Pennsylvania, said at the annual meeting of the American Academy of Dermatology. The recommendation was based on a pooled analysis of four randomized controlled trials that found patients with acne who used the medications were more likely to have improvement via the Investigator Global Assessment (IGA) scale at 12 weeks than were those treated with a vehicle (risk ratio [RR], 1.57; 1.21-2.04).

The updated guidelines were published on January 30 in the Journal of the American Academy of Dermatology. The previous guidelines were issued in 2016.

“We have four current retinoids that we use: adapalene, tretinoin, tazarotene, and trifarotene,” Dr. Zaenglein said. “Typically, when we think about retinoids, we think of adapalene as being more tolerable and tazarotene as being more effective. But we also know that they can work to prevent and treat scarring, and they work against comedonal lesions and inflammatory lesions.”

Newer concentrations include tretinoin 0.05% lotion, tazarotene 0.045% lotion, and trifarotene 0.005% cream. She noted that this trifarotene concentration can be helpful for moderate truncal acne and also referred to evidence that whey protein appears to exacerbate that condition. “I always ask teenage kids about that: Are they using those protein powders?”
 

Recommendations for ‘Multimodal Therapy,’ Especially With Antibiotics

Dr. Zaenglein highlighted a “good practice statement” in the new guidelines that says, “when managing acne with topical medications, we recommend multimodal therapy combining multiple mechanisms of action.”

Topical antibiotics are effective treatments on their own and include erythromycin, clindamycin, and minocycline (Minocin), she said. But the guidelines, which refer to evidence supporting them as “moderate,” do not recommend them as monotherapy because of the risk for antibiotic resistance.

The oral retinoid isotretinoin may be appropriate in conjunction with topical medications, she said, “and we also recommend fixed combination products because they’re associated with increased adherence.”

Dermatologists are familiar with several of these products because “we’ve been using them for years and years,” she said. The guidelines note that “compared to vehicle at 12 weeks, a greater proportion of patients treated with combined BP and topical retinoid achieved IGA success in three RCTs (RR, 2.19; 1.77-2.72).”

Dr. Zaenglein noted that the guidelines recommend that patients taking antibiotics also use benzoyl peroxide, which has “moderate” evidence regarding preventing the development of antibiotic resistance. “Lower strengths tend to be less irritating, and over-the-counter formulations are readily available,” she said, adding that colleagues should make sure to warn patients about the risk of bleaching clothes and towels with BP.

Now, there’s a newly approved treatment, the first fixed-dose triple combination therapy for acne, she said. It combines 1.2% clindamycin, 3.1% benzoyl peroxide, and 0.15% adapalene (Cabtreo) and is Food and Drug Administration (FDA)-approved for treating acne in patients ages 12 and up.

The new AAD guidelines note that “potential adverse effect profiles of the fixed-dose combinations generally reflect those of the individual agents in summation. Some fixed-dose combination products may be less expensive than prescribing their individual components separately.” The evidence supporting fixed-dose combinations in conjunction with benzoyl peroxide is considered “moderate.”

Dapsone gel, 7.5% (Aczone) is another option for acne. “It’s a topical so you don’t need to do G6PD [glucose-6-phosphate dehydrogenase] testing,” Dr. Zaenglein said. “It’s well tolerated, and mean total lesions fell by 48.9% vs 43.2% for vehicle,” in a 2018 study, which she said also found that females benefited more than males from this treatment.

Clascoterone 1% cream (Winlevi), approved in 2020, is appropriate for males and females aged 12 and up, Dr. Zaenglein said. She noted that it’s the only topical anti-androgen that can be used in males. However, while it has a “high” level of evidence because of phase 3 clinical trials showing benefits in moderate to severe acne, the AAD guidelines only conditionally recommend this option because the high price of clascoterone “may impact equitable acne treatment access.” The price listed on the website GoodRx (accessed on March 12) lists drugstore prices for a single 60-gram tube as ranging from $590 to $671.

There are no data for dapsone and clascoterone during pregnancy/lactation, and minocycline is “not recommended.”

Hi. I’m Brian Rini. I’m an Ingram Professor of Medicine at Vanderbilt-Ingram Cancer Center in Nashville, Tennessee. I’m going to talk to you briefly today about some major highlights in renal cancer from the Genitourinary (GU) Cancer Symposium that was just held. I think there’s three main areas: adjuvant therapy in kidney cancer, frontline therapy in advanced disease, and the refractory space.

To open with adjuvant therapy, the biggest news in kidney cancer, and probably all of GU cancer at ASCO GU this year, was the adjuvant pembrolizumab overall survival data. This KEYNOTE study had previously shown disease-free survival advantages over placebo in a population with high-risk resected kidney cancer. There was a trend toward overall survival, but it was not significant in those early analyses.

Now with nearly 5 years of follow-up, we see an overall survival advantage, with a hazard ratio in the 0.6 range — so, about a 40% reduction in the risk for death among these patients receiving adjuvant pembrolizumab (pembro). This was really important for the field. It’s been difficult to show a survival advantage, even in diseases like melanoma, which is considered at least as much, if not more immune responsive, and I think puts into perspective whether to offer this drug to high-risk resected patients. And it certainly needs to be considered for this population.

I think the balance on that — and this came out in some of the questions after the session — was around how many of the placebo recipients got salvage immune therapy, which would be a standard of care. But in the countries where this was done, it’s not really clear how many actually got therapy. We know most patients got some salvage therapy, be it local or systemic, and about half the patients got immune therapy. But some more granular detail would be necessary.

The other thing I would mention is that this was paired with the previous presentation, which was adjuvant nivolumab. It was a very similar study, a similar drug in a similar setting, but it did not show any advantages of either disease-free or overall survival. This comes on the heels of other negative studies and a negative ipilimumab/nivolumab (ipi/nivo) study in this setting, part of the same study.

The reasons for these discrepancies are not entirely clear. There’s differences in populations and duration of therapy and mechanism, and all sorts of things. I don’t think anybody’s really been able to come up with one reason why we have some negative immune trials in kidney cancer and one shiningly positive one. But be that as it may, I think the take-home was that adjuvant pembro is certainly a standard of care in high-risk disease, and a benefit/risk discussion needs to be had with each individual patient. And I think pembro will be the building block for future studies, some of which are ongoing.

The second major area of update was in frontline kidney cancer. There weren’t a lot of new data, but there were updates to the existing trials. As you may know, frontline immune-based doublet is a standard of care in this disease: either ipi/nivo or one of the immuno-oncology/tyrosine kinase inhibitor (IO/TKI) regimens. We had two updates. One was an 8-year update on ipi/nivo. It’s a really long follow-up for these patients now, and what was observed was that these results remain remarkably consistent.

The hazard ratios for benefit in terms of survival and durability of response are really consistent over the past several years — again, a hallmark of immune therapy. Over half the responders are still responding now, many years later. I think that only strengthens the position of ipi/nivo as a choice for advanced clear cell kidney cancer patients. Again, there are good long-term toxicity data, and some patients can remain off treatment in what’s called treatment-free survival. So, an important update. We look forward to future, probably 10-year, data.

The CheckMate 9ER cabozantinib/nivolumab (cabo/nivo) study was updated now with many years of follow-up, as some of the other IO/TKI regimens have as well. And I think there is a similar theme, although a few years behind in maturity from the ipi/nivo data. It shows persistence of benefit. With IO/TKI regimens, a lot of the benefit is up front. It’s high response rates. It’s progression-free survival (PFS). But we’re starting to see some of that durability.

Where it’ll land, if there will be a tail of the curve and where it will be, is unclear, but these updates are important in terms of counseling patients. Patients want to know not just what’s going to happen at their first scan but also years from now. And they’re planning to be around years from now. So, I think these data are important.

The last thing I’ll mention is a health-related quality-of-life update from what was called the 005 trial of belzutifan, an oral HIF inhibitor, compared with everolimus. We heard data at the European Society for Medical Oncology (ESMO) Congress 2023 on a PFS and response-rate advantage. The drug was approved by the US Food and Drug Administration (FDA) in late December, and now we see some quality-of-life data.

Quality-of-life questionnaires and scales have a lot of imperfections. I don’t think they necessarily capture everything we want. But in this case, it was fairly clean in that belzutifan is known to be a well-tolerated agent. The toxicity profile is clean. It’s been used for years in patients with Von Hippel-Lindau syndrome, certainly in the trials for years, and has shown good tolerance over time. So, I view these data as complementary to what we already knew about the drug, but they’re nice to see.

It’s nice to see datasets come together and show the same thing: Not only is the drug active in a refractory renal cell carcinoma (RCC) setting, but also it’s really well tolerated and does not adversely impact patients› quality of life. I use this drug a lot in refractory kidney cancer, and because it’s so well tolerated. That means it’s also combinable. And there are some very large studies in the front-end second-line space combining it, in a space where people believe that it has more activity. But there are some complementary data as we wait for the overall survival signal, hopefully, from this regimen.

So, there have been some exciting updates, mostly in the adjuvant space but also in some other spaces in kidney cancer and building upon some of the clinical advances that we had seen from previous meetings. I’m Brian Rini, and I appreciate you attending.
