Patients with Moderate-to-Severe Atopic Dermatitis Maintain Stable Response with No or Minimal Fluctuations with 1 Year of Lebrikizumab Treatment.

INTRODUCTION: Lebrikizumab is a novel monoclonal antibody with established efficacy in patients with moderate-to-severe atopic dermatitis (AD) in multiple Phase 3 trials. One of the ultimate treatment goals for patients with moderate-to-severe AD is to achieve stable disease control without concern for planning future life events. METHODS: In ADvocate1 and ADvocate2, lebrikizumab-treated patients meeting the protocol-defined response criteria at Week 16 were re-randomized 2:2:1 to receive lebrikizumab every 2 weeks (Q2W), lebrikizumab every 4 weeks (Q4W), or placebo Q2W (lebrikizumab withdrawal) for 36 additional weeks. In this post hoc analysis, we evaluated the proportions of patients with no or minimal fluctuations of efficacy during the 36-week maintenance period and plotted individual patient trajectories. We defined no or minimal fluctuations as achieving and maintaining the defined endpoint (≥ 75% improvement in the Eczema Area and Severity Index [EASI 75], ≥ 90% improvement in EASI, Pruritus Numeric Rating Scale [NRS] ≥ 4-point improvement, or Pruritus NRS ≥ 3-point improvement) for ≥ 80% of the study visits. If patients used rescue medication, discontinued treatment, or transferred to the escape arm, data collected at or after the event were imputed as non-response. RESULTS: The proportions of lebrikizumab responders who maintained EASI 75 with no or minimal fluctuations were 70.8% (lebrikizumab Q2W), 71.2% (lebrikizumab Q4W), and 60.0% (lebrikizumab withdrawal). Of the patients with baseline Pruritus NRS ≥ 4 and who achieved ≥ 4-point improvement at Week 16, 66.1% (lebrikizumab Q2W), 62.7% (lebrikizumab Q4W), and 55.2% (lebrikizumab withdrawal) maintained ≥ 4-point Pruritus NRS improvement with no or minimal fluctuations. CONCLUSIONS: Patients who met the response criteria at Week 16 and continued treatment with lebrikizumab Q2W or Q4W demonstrated a stable response with no or minimal fluctuations of efficacy in measures of skin and itch up to Week 52. CLINICAL TRIAL REGISTRATION: NCT04146363 (ADvocate1) and NCT04178967 (ADvocate2).

Atopic dermatitis, also known as atopic eczema (or just eczema), is a common skin disease that causes itchy, dry skin. Patients with eczema are often unsure of when disease flares will happen, even while receiving treatment. In two global studies, ADvocate1 and ADvocate2, lebrikizumab improved the signs and symptoms of moderate-to-severe eczema after 16 weeks of treatment. Most of these patients also saw improvement up to 52 weeks. We wanted to know if patients continued to feel better between Week 16 and Week 52. Patients who responded to lebrikizumab after 16 weeks were given lebrikizumab every 2 weeks, lebrikizumab every 4 weeks, or placebo every 2 weeks. We tested how many patients experienced stable response to therapy, which we said was maintaining the same level of improvement on skin signs and itch symptoms for at least 80% of study visits from Week 16 to Week 52. In patients treated with lebrikizumab every 2 weeks or every 4 weeks, we saw that about seven of every ten patients maintained a stable response in skin improvement and about six of every ten patients maintained stable response in itch symptoms. In patients who stopped lebrikizumab therapy, six out of every ten patients maintained a stable skin improvement and more than five of every ten patients maintained a stable improvement in itch symptoms. In ADvocate1 and ADvocate2, most lebrikizumab-treated patients showed a stable response over time on skin and itch with dosing every 2 weeks or every 4 weeks.

Clindamycin: A Comprehensive Status Report with Emphasis on Use in Dermatology.

Clindamycin is a lincosamide antibiotic that has been used as a topical, oral, or injectable formulation for over five decades. It exhibits a narrow spectrum of microbiologic activity, primarily against gram-positive and anaerobic bacteria. In dermatology, clindamycin has been used primarily as a topical agent, usually for the treatment of acne vulgaris. Despite questions surrounding antibiotic resistance and/or its relative contribution to antibiotic treatment efficacy, a large body of data support the therapeutic value of topical clindamycin for acne vulgaris. As a systemic agent, clindamycin is used orally to treat a variety of cutaneous bacterial infections, and sometimes for acne vulgaris, with oral treatment for the latter less common in more recent years. The modes of action of clindamycin are supported by data showing both its anti-inflammatory and antibiotic mechanisms, which are discussed here along with pharmacokinetic profiles and structure-activity relationships. The diverse applications of clindamycin for multiple disease states, its efficacy, and safety considerations are also reviewed here, including for both topical and systemic formulations. Emphasis is placed on uses in dermatology, but other information on clindamycin relevant to clinicians is also discussed.

Developing a questionnaire for assessing clinician- and patient-reported outcomes in actinic keratosis: Results from an expert panel.

Background: Current assessments on topical treatment attributes in actinic keratosis (AK) do not evaluate safety, effectiveness, and satisfaction from both clinician and patient perspectives, creating an unmet need for more comprehensive AK-specific measures that fully capture the patient experience. Objective: To develop an actinic keratosis-specific expert panel questionnaire (AK-EPQ) of patient-reported outcomes and clinician-reported outcomes for use in research studies. Methods: Using interviews of patients with AK and targeted literature reviews, a 9-person consensus panel of dermatologists with expertise in AK treatment was convened to develop the AK-EPQ to assess AK-specific patient-reported outcomes and clinician-reported outcomes. Results: Nine expert advisers achieved consensus on 11 AK-EPQ items that encompass patient and clinician perspectives of treatment-related local skin reactions, clinical and cosmetic outcomes associated with AK, and satisfaction with treatment; the AK-EPQ will be first implemented in the Patient-Reported Outcomes for Actinic Keratosis study (NCT05260073). Limitations: The AK-EPQ does not directly measure quality of life, although it can be used with validated quality of life instruments. Conclusion: The newly developed AK-EPQ elicits insights into the patient and clinician experience with AK treatments. Comparative probing of these perspectives may help optimize precision medicine in AK treatment.

Efficacy and Safety of Micronized Isotretinoin Administered Once Daily Without Food in Patients With Recalcitrant Nodular Acne.

INTRODUCTION: Micronized isotretinoin 0.4 to 0.8 mg/kg/day administered in 2 divided doses with or without meals is approved for the treatment of severe nodular acne in patients aged 12 years or older. Although practitioners may suggest once-daily dosing to increase patient compliance, supporting data are limited. METHODS: In this pilot study, patients aged 12 years or older with severe nodular acne (Investigator's Global Assessment [IGA] =>4 and >5 facial nodules) received once-daily micronized isotretinoin 0.4 to 0.8 mg/kg/day without food for 20 weeks. The coprimary efficacy endpoints were changes from baseline in nodular lesion count (NLC) and percentage of patients with a =>90% reduction in NLC at week 24. Secondary endpoints included percentage of patients achieving IGA 0/1; reductions in inflammatory lesion count (ILC) and noninflammatory lesion count (NILC); adverse events (AEs); and severity of erythema, dryness, peeling, oiliness, burning, and pruritus. Analyses included all enrolled patients with the last observation carried forward. RESULTS: Twenty-two of 24 patients completed the study. From baseline to week 24, NLC decreased by a median (quartile [Q]1, Q3) of 6 (5, 7), all patients experienced complete clearance of nodules, 23/24 (96%) patients achieved IGA 0/1, and ILC and NILC decreased by a mean +/- standard deviation of 97.8% +/- 5.7% and 98.4% +/- 6.2%, respectively (all P<0.0001). There were small, significant, early increases in the severity of erythema, dryness, and peeling; 2 patients experienced 3 AEs considered unrelated to treatment. CONCLUSIONS: Once-daily micronized isotretinoin administered without food was efficacious and well tolerated in patients with severe nodular acne.  J Drugs Dermatol. 2024;23(6):423-428.     doi:10.36849/JDD.7863.

Consensus Statements on the Use of Novel Formulations of Isotretinoin: A Modified Delphi Process.

Oral isotretinoin remains a mainstay of treatment for severe, recalcitrant nodular acne. Novel formulations of isotretinoin have been developed over the past decade, including lidose isotretinoin and micronized isotretinoin. It is important to understand the differences between isotretinoin formulations to help guide clinical decision-making and selection of isotretinoin therapy. This study aims to provide evidence-based consensus statements regarding the use of novel formulations of isotretinoin for the treatment of moderate-to-severe acne. The Expert Consensus Group consisted of dermatologists with expertise in the treatment of acne. Voting members met in person to conduct a modified Delphi process; a maximum of 2 rounds of voting were conducted for each consensus statement. A total of 5 statements were generated regarding the use of novel formulations of isotretinoin, addressing the efficacy, tolerability, and side effects of novel isotretinoin formulations. All 5 statements achieved agreement with high consensus. The Expert Consensus Group agrees that individualized selection of isotretinoin therapy is important to maximize efficacy and minimize side effects. Compared to generic isotretinoin, micronized isotretinoin may require lower doses to achieve sufficient plasma concentrations. With the increased bioavailability of micronized formulation, there is no need to calculate cumulative dose; instead, the general recommendation with micronized isotretinoin is to treat for at least 5 months, or longer if needed to achieve clearance. Micronized isotretinoin can be taken in the fed or fasted state and has an acceptable safety profile. J Drugs Dermatol. 2024;23(6):429-432.     doi:10.36849/JDD.7971.

Topical Clindamycin in the Management of Acne Vulgaris: Current Perspectives and Recent Therapeutic Advances.

Clindamycin is a lincosamide-derivate antibiotic that has been widely used both systemically and topically for approximately 5 decades. The antimicrobial profile of clindamycin primarily covers several gram-positive bacteria and anaerobic bacteria, with multiple clinical applications supported in the literature and with widespread real-world use. Topical clindamycin has been used primarily for the treatment of acne vulgaris, with both monotherapy and combination therapy formulations available commercially. This article reviews the use of clindamycin as a topical agent with emphasis on therapy for acne vulgaris, and addresses modes of action, reported anti-inflammatory properties that may relate to therapeutic outcomes, recommendations to avoid the emergence of antibiotic-resistant bacteria, tolerability and safety considerations, and published data from clinical studies completed over a span of several years. A discussion of a newly FDA-approved triple-combination formulation is also included.  J Drugs Dermatol. 2024;23(6):438-445.     doi:10.36849/JDD.8318.

Going Beyond Ceramides in Moisturizers: The Role of Natural Moisturizing Factors.

Xerosis is experienced by almost everyone at some time in their lives and the foundation of management of dry skin (both consumer- and healthcare professional--directed) rests on the use of moisturizers. Given the wide range of available moisturizers, counseling patients about selecting the optimum moisturizer for their individual situation relies on knowledge of ingredients and formulations. Traditionally, the main focus for many moisturizers centered on the core functional and structural role of ceramides within the epidermal barrier.  However, while a key aspect of transepidermal water loss and other skin barrier functions, components other than ceramides are equally essential in increasing moisturization. The skin's natural moisturizing factors (NMFs) are a complex mixture of water-attracting compounds such as amino acids, urea, lactate, pyrrolidone carboxylic acid (PCA), and electrolytes which play a fundamental role in preserving physiologic function by regulating the water content of the stratum corneum. By facilitating water retention, NMFs contribute significantly to the suppleness, elasticity, normal desquamation, and overall integrity of the skin barrier. Incorporation of NMFs into moisturizers addresses critical deficiencies in the skin's moisture balance that exist in xerotic and atopic skin, and in many skin disorders, mitigating signs and symptoms associated with xerosis and promoting optimal skin health. The biochemical composition of NMFs and the intricate interplay with epidermal homeostasis translate to a central role in moisturizers used for prophylactic and therapeutic management of various dry skin conditions, beyond ceramides alone.

Triple Combination Clindamycin Phosphate 1.2%/Adapalene 0.15%/Benzoyl Peroxide 3.1% for Acne: Efficacy and Safety from a Pooled Phase 3 Analysis.

INTRODUCTION: A three-pronged approach to acne treatment combining an antibiotic, antimicrobial, and retinoid may be more efficacious than single/double treatments while potentially reducing antibiotic resistance. This study evaluated the efficacy and safety of the first fixed-dose, triple-combination topical acne product, clindamycin 1.2%/adapalene 0.15%/benzoyl peroxide (BPO) 3.1% gel (CAB) using pooled phase 3 data. METHODS: In two identical phase 3 (N = 183; N = 180), double-blind, 12-week studies, participants aged ≥ 9 years with moderate-to-severe acne were randomized 2:1 to receive once-daily CAB or vehicle gel. Endpoints included ≥ 2-grade reduction from baseline in Evaluator's Global Severity Score and clear/almost clear skin (treatment success) and least-squares mean percent change from baseline in acne lesion counts. Treatment-emergent adverse events (TEAEs) and cutaneous safety/tolerability were evaluated. RESULTS: At week 12, 50.0% of participants achieved treatment success with CAB versus 22.6% with vehicle gel (P < 0.001). CAB resulted in > 70% reductions in inflammatory and noninflammatory lesions at week 12 (77.9% and 73.0%, respectively), which were significantly greater than vehicle (57.9% and 48.2%; P < 0.001, both). Most TEAEs were of mild-moderate severity, and < 3% of CAB-treated participants discontinued study/treatment because of AEs. Transient increases from baseline in scaling, erythema, itching, burning, and stinging were observed with CAB, but resolved back to or near baseline values by week 12. CONCLUSIONS: The innovative fixed-dose, triple-combination clindamycin phosphate 1.2%/adapalene 0.15%/BPO 3.1% gel was efficacious and well tolerated in children, adolescents, and adults with moderate-to-severe acne. Half of participants achieved clear/almost clear skin by 12 weeks, rates not previously seen in clinical studies of other topical acne products. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT04214639 and NCT04214652.

Antiseptic and Antibiotic Stewardship in Dermatologic Surgery: Is Benzoyl Peroxide the Solution?

Objective: We sought to review published literature on antibiotic and antiseptic use and resistance, and explore the utility of benzoyl peroxide in this capacity for dermatologic surgery. Methods: A literature review was performed to investigate the skin microbiome, guidelines on antibiotic and antiseptic use in dermatologic surgery, and the utility of benzoyl peroxide as an antiseptic. Results: Antiseptics are commonly used in dermatologic surgery to prepare surgical sites, and antibiotics are also employed by some physicians to prevent post-operative infection despite the potential for antibiotic resistance. Benzoyl peroxide, known for its high threshold for antibiotic resistance, has been successfully used in orthopedic surgery to prevent surgical site infection, especially in sebaceous areas of the skin which house a distinct microbiota. Limitations: Limitations to this review include lack of high-quality, adequately powered research and studies which evaluate the clinical impact of anti-septic use, particularly benzoyl peroxide use, in dermatologic surgery. Conclusion: Benzoyl peroxide may be a used as an antiseptic in dermatologic surgery of sebaceous areas to prevent post-operative infections, with a low likelihood of causing microbial resistance.

Rosacea Core Domain Set for Clinical Trials and Practice: A Consensus Statement.

Importance: Inconsistent reporting of outcomes in clinical trials of rosacea is impeding and likely preventing accurate data pooling and meta-analyses. There is a need for standardization of outcomes assessed during intervention trials of rosacea. Objective: To develop a rosacea core outcome set (COS) based on key domains that are globally relevant and applicable to all demographic groups to be used as a minimum list of outcomes for reporting by rosacea clinical trials, and when appropriate, in clinical practice. Evidence Review: A systematic literature review of rosacea clinical trials was conducted. Discrete outcomes were extracted and augmented through discussions and focus groups with key stakeholders. The initial list of 192 outcomes was refined to identify 50 unique outcomes that were rated through the Delphi process Round 1 by 88 panelists (63 physicians from 17 countries and 25 patients with rosacea in the US) on 9-point Likert scale. Based on feedback, an additional 11 outcomes were added in Round 2. Outcomes deemed to be critical for inclusion (rated 7-9 by ≥70% of both groups) were discussed in consensus meetings. The outcomes deemed to be most important for inclusion by at least 85% of the participants were incorporated into the final core domain set. Findings: The Delphi process and consensus-building meetings identified a final core set of 8 domains for rosacea clinical trials: ocular signs and symptoms; skin signs of disease; skin symptoms; overall severity; patient satisfaction; quality of life; degree of improvement; and presence and severity of treatment-related adverse events. Recommendations were also made for application in the clinical setting. Conclusions and Relevance: This core domain set for rosacea research is now available; its adoption by researchers may improve the usefulness of future trials of rosacea therapies by enabling meta-analyses and other comparisons across studies. This core domain set may also be useful in clinical practice.

Topical clindamycin for acne vulgaris: analysis of gastrointestinal events.

Purpose: Topical clindamycin, a lincosamide antibiotic, is commonly combined with benzoyl peroxide or a retinoid for acne vulgaris (AV) treatment. While oral and topical clindamycin carry warnings/contraindications regarding gastrointestinal (GI) adverse events (AEs), real-world incidence of GI AEs with topical clindamycin is unknown. This review provides background information and an overview of safety data of topical clindamycin for treating AV.Materials and Methods: Available safety data from published literature, previously unpublished worldwide pharmacovigilance data, and two retrospective cohort studies were reviewed.Results and Conclusions: According to pharmacovigilance data, the rate of GI adverse drug reactions with topical clindamycin-containing products was 0.000045% (64/141,084,533). Results from two retrospective medical record studies of patients with AV indicated that physicians prescribe topical clindamycin equally to patients with or without inflammatory bowel disease history, and that rates of pseudomembranous colitis in these patients were low. In 8 published pivotal clinical trials of topical clindamycin for AV, GI AEs were reported in 1.4% of participants. Limitations include under/inaccurate reporting of AEs or prescription data and limited generalizability. This review of published case reports, worldwide pharmacovigilance data, retrospective US prescription data, and clinical trials safety data demonstrates that the incidence of colitis in patients exposed to topical clindamycin is extremely low.

Importance of treating acne sequelae in skin of color: 6-month phase IV study of trifarotene with an appropriate skincare routine including UV protection in acne-induced post-inflammatory hyperpigmentation.

BACKGROUND: Acne-induced hyperpigmentation (AIH) may accompany acne vulgaris (AV) inflammation in all skin phototypes. Trifarotene has shown depigmenting properties in vivo. This study evaluated trifarotene plus skincare because it is increasingly recognized that holistic AV management should include skincare and treatments. METHODS: This is a phase IV double-blind, parallel-group study of patients (13-35 years) with moderate AV and AIH treated with trifarotene (N = 60) or vehicle (N = 63) plus skincare regimen (moisturizer, cleanser, and sunscreen) for 24 weeks. Assessments included the AIH overall disease severity (ODS) score, post-AV hyperpigmentation index (PAHPI), exit interviews, photography, and acne assessments. Standard safety assessments were included. RESULTS: Trifarotene 50 µg/g cream improved significantly from baseline in ODS score versus vehicle (-1.6 vs. -1.1, P = 0.03) at Week 12, but scores were comparable between groups at Week 24 (primary endpoint). Trifarotene had a better reduction in PAHPI score at Week 24 (-18.9% vs. -11.3% vehicle, P < 0.01). Lesion count reductions were higher with trifarotene at Week 12 versus vehicle (P < 0.001) and at Week 24 (P < 0.05), as were IGA success rates versus vehicle at Weeks 12 (P < 0.05) and 24 (P < 0.05). Patients agreed that the skincare regimen contributed to less irritation, making treatment adherence easier. Photography showed improvements in pigmentation and erythema across all skin types. AEs were more common in the vehicle group versus trifarotene (30.2 vs. 16.7%, respectively). CONCLUSIONS: In all skin phototypes, there was more rapid improvement in the ODS and PAHPI scores with trifarotene by Weeks 12 and 24, respectively. The combination of trifarotene and skincare correlated with high patient satisfaction and adherence to the treatment protocol.

COVID-19 Protection Strategies: Lessons Learned About Epidermal Barrier Function and the Significance of Optimized Skin Care.

Initially categorized as primarily a respiratory disease, COVID-19 can involve other organ systems and may have direct skin manifestations, including exanthems, morbilliform eruption, generalized urticaria, or pseudo-chilblains —commonly called “COVID Toes.” Frequent handwashing and prolonged wearing of face masks and shields in efforts to minimize transmission of SARS-CoV-2, the novel coronavirus that causes COVID, has given rise to indirect skin manifestations of COVID. “Maskne” and handwashing dermatitis are particularly common among healthcare workers. Characterized by skin inflammation, dryness, pruritus, and other symptoms, these conditions are fundamentally disorders of skin barrier dysfunction. This dysfunction may result from the combination of mechanical skin damage, changes in skin pH, reductions in skin lipids attributable to protection measures, and local alterations in the cutaneous microbiome. Strategies to manage these conditions focus on reversing and repairing skin barrier damage with preventative general measures, optimized skin care with the selection of proper products, eliminating irritant exposures, and avoiding certain medications, such as topical corticosteroids, that may further impair barrier function despite temporary improvement in signs and symptoms. J Drugs Dermatol. 2024;23(4):  doi:10.36849/JDD.7862.

Scientific Rationale and Clinical Basis for Clindamycin Use in the Treatment of Dermatologic Disease.

Clindamycin is a highly effective antibiotic of the lincosamide class. It has been widely used for decades to treat a range of skin and soft tissue infections in dermatology and medicine. Clindamycin is commonly prescribed for acne vulgaris, with current practice standards utilizing fixed-combination topicals containing clindamycin that prevent Cutibacterium acnes growth and reduce inflammation associated with acne lesion formation. Certain clinical presentations of folliculitis, rosacea, staphylococcal infections, and hidradenitis suppurativa are also responsive to clindamycin, demonstrating its suitability and versatility as a treatment option. This review describes the use of clindamycin in dermatological practice, the mechanism of protein synthesis inhibition by clindamycin at the level of the bacterial ribosome, and clindamycin's anti-inflammatory properties with a focus on its ability to ameliorate inflammation in acne. A comparison of the dermatologic indications for similarly utilized antibiotics, like the tetracycline class antibiotics, is also presented. Finally, this review addresses both the trends and mechanisms for clindamycin and antibiotic resistance, as well as the current clinical evidence in support of the continued, targeted use of clindamycin in dermatology.

Natural Moisturizing Factor-Enriched Formulations Compared to a Ceramide-Based Cream.

BACKGROUND: We aimed to investigate the effects of 2 ceramide plus natural moisturizing factor-enriched formulations compared to a ceramide-based cream on skin moisturization. METHODS: Two double-blinded comparative studies were conducted, which enrolled 35 (n=29 females, n=6 males) and 33 (n=21 females, n=12 males) participants, respectively. Participants applied ceramide plus natural moisturizer cream or ceramide-based cream (study 1) or applied ceramide plus natural moisturizing factor lotion or ceramide-based cream (study 2) to each of their lower legs for 10 days with a 5-day regression period (no moisturizer applied). Skin hydration by corneometry after bilateral application was conducted once daily for each leg in both groups.   Results: An increase in corneometer units vs baseline for the ceramide plus natural moisturizing factor-enriched cream and natural moisturizing factor-enriched lotion were greater than the increase vs baseline for the ceramide-based cream at days 10 and 15; with an overall statistical significance in favor of the ceramide plus natural moisturizing factor-enriched formulations at day 10.  Conclusions: The marked improvement in skin moisturization following utilization of the ceramide plus natural moisturizing  factor-enriched cream and lotion compared to the ceramide-based cream can be attributed to the inherent properties of the natural moisturizing factors. These properties are known to maintain the humectancy and intercellular lipid membrane of the stratum corneum, which directly improves the permeability barrier function of human skin in reducing transepidermal water loss.

Microencapsulated Benzoyl Peroxide for Rosacea in Context: A Review of the Current Treatment Landscape.

Rosacea, a chronic skin condition affecting millions of people in the USA, leads to significant social and professional stigmatization. Effective management strategies are crucial to alleviate symptoms and improve patients' quality of life. Encapsulated benzoyl peroxide 5% (E-BPO 5%) is a newly FDA-approved topical treatment for rosacea that shows promise in enhancing therapeutic response and minimizing skin irritation. This review aims to assess the role of recently FDA approved E-BPO 5% in the current treatment landscape for rosacea management, as it is not yet included in clinical guidelines that predominantly rely on older approved therapies. The review focuses on randomized controlled trials conducted in English-speaking adults. It evaluates the efficacy, safety, and tolerability of various US Food and Drug Administration (FDA)-approved agents used for rosacea treatment, including E-BPO cream, metronidazole gel, azelaic acid gel and foam, ivermectin cream, minocycline foam, oral doxycycline, brimonidine gel, and oxymetazoline HCl cream. Existing therapies have been effective in reducing papulopustular lesions and erythema associated with rosacea for many years. E-BPO 5% offers a promising addition to the treatment options due to its microencapsulation technology, which prolongs drug delivery time and aims to improve therapeutic response while minimizing skin irritation. Further research is necessary to determine the exact role of E-BPO 5% in the therapeutic landscape for rosacea. However, based on available evidence, E-BPO 5% shows potential as a valuable treatment option for managing inflammatory lesions of rosacea, and it may offer benefits to patients including: rapid onset of action, demonstrated efficacy by Week 2, excellent tolerability, and sustained long-term results for up to 52 weeks of treatment.

Incorporating a Prognostic Gene Expression Profile Test into the Management of Cutaneous Squamous Cell Carcinoma: An Expert Consensus Panel Report.

BACKGROUND:  Cutaneous squamous cell carcinoma (cSCC) is a growing health concern with a rapidly increasing incidence. Disease-specific mortality is typically preceded by a metastasis, but current staging systems have significant limitations in predicting this event. The 40-gene expression profile (40-GEP) test is a validated method of further stratifying patients based on the risk of regional or distant metastasis, but limited guidelines exist for incorporating this test into clinical practice. OBJECTIVE:  To review the available literature on the use of gene expression profile (GEP) testing to assess prognosis in cSCC and create consensus statements to guide dermatology clinicians on its use. METHODS:  A comprehensive literature search of PubMed, EMBASE, and Scopus was completed for English-language original research articles on the use of GEP testing to assess cSCC prognosis. A panel of 8 dermatologists with significant expertise in diagnosing and managing cSCC gathered to review the articles and create consensus statements. A modified Delphi process was used to approve each statement and a strength of recommendation was assigned using the Strength of Recommendation Taxonomy (SORT) criteria. RESULTS:  The literature search produced 157 articles that met the search criteria. A thorough screening of the studies for relevance to the research question resulted in 21 articles that were distributed to the panelists for review prior to the roundtable discussion. The panel unanimously voted to adopt 7 consensus statements and recommendations, 6 of which were given a strength of "A" and 1 of which was given a strength of "C". CONCLUSION:  The 40-GEP test provides accurate and independent prognostic information beyond standard staging systems that only incorporate pathologic data. Incorporation of GEP testing into national guidelines can help further stratify patients based on risk of metastasis and thus may improve morbidity and mortality.

New Insights Into Systemic Drivers of Inflammation and Their Contributions to the Pathophysiology of Acne.

Acne Vulgaris (AV) is a prominent skin disease commonly affecting teenagers. It often persists into adulthood and is associated with adverse physical and psychosocial impacts. The pathophysiology of AV is conventionally correlated with 4 factors within and around the pilosebaceous unit: increased sebum production, follicular hyperkeratinization, Cutibacterium acnes proliferation, and localized immune responses. As such, conventional therapeutic approaches for AV have primarily focused on these factors. In addition to this primarily localized pathophysiology, there is a progressively emerging body of evidence indicating that underlying systemic factors contributing to a generalized immuno-inflammatory response can contribute to or exacerbate AV. In this article, we introduce and provide the supporting data, for 6 patient-centric systems that may be implicated in the development of AV: psycho-emotional stress, diet and metabolism, dysbiosis of the gut and skin microbiome, hormonal fluctuations, oxidative stress, and immune response. Identifying these pathways and their contributions in a patient-centric approach may provide expanded therapeutic opportunities for treating patients with AV.

INDIVIDUAL ARTICLE: Impact of Acne Vulgaris and Sarecycline on Social/Emotional Functioning and Daily Activities: PROSES Study.

BACKGROUND: Concise patient-reported outcome (PRO) instruments addressing the consequences of facial acne vulgaris (AV) on patients’ functioning and activities of daily living (ADL) are needed. METHODS: A 12-week, single-arm, prospective cohort study was conducted in patients ≥9 years old with moderate/severe non-nodular facial AV prescribed sarecycline as part of usual care. The primary endpoint included AV-specific patient- and caregiver-reported outcomes assessed with the expert panel questionnaire (EPQ, developed by 10 experts using a Delphi method) in patients (>12 years) and caregivers (for patients 9-11 years). Additional assessments included parental/caregiver perspectives on children’s AV. RESULTS: A total of 253 patients completed the study. Following 12-weeks of treatment, there were significant (P ≤.0001) changes from baseline in the proportion of patients responding that they never or rarely: felt angry (31.6%), worried about AV worsening (28.9%), had thoughts about AV (20.9%), had a certain level of worries about AV (38.7%), altered their social media/selfie activity (23.7%), had an impact on real-life plans due to AV (22.9%), made efforts to hide AV (21.3%), felt picked-on/judged due to AV (15.0%), were concerned about their ability to reach future goals due to AV (13.8%), or had sleep impacted due to AV (18.2%). No significant change from baseline was observed for parent/caregiver’s understanding of the child’s AV concerns, from both patient and parent/caregiver perspectives. CONCLUSIONS: Over 12 weeks of AV management with oral sarecycline, patients reported significant reductions in AV-related effects on emotional/social functioning and ADL as measured by the EPQ, a simple PRO with potential for use in clinical practice.
