Topical Prescription Management.

With recent advances in topical therapies for atopic dermatitis (AD), steroid-sparing options like calcineurin inhibitors, Janus kinase (JAK) inhibitors, and phosphodiesterase-4 (PDE-4) inhibitors are becoming mainstays in therapy, underscoring the importance of careful selection and usage of topical corticosteroids (TCSs) to minimize side effects. Alongside the necessity of emollient use, these steroid-sparing alternatives offer rapid itch relief and efficacy in improving disease severity. While TCSs still hold a prominent role in AD management, promising novel topical treatments like tapinarof and live biotherapeutics to modulate the skin microbiome are also discussed. Overall, the recent addition of novel topical therapies offers diverse options for AD management and underscores the importance of topical treatments in the management of AD.

The Future of Atopic Dermatitis Treatment.

This chapter thoroughly examines recent breakthroughs in atopic dermatitis (AD) treatment, with a primary focus on the medications in the development pipeline. Biologics agents targeting new interleukin receptors like interleukin-31, interleukin-22, and interleukin-2 are discussed along with the novel pathway looking at the OX40-OX40L interaction. Oral agents and small molecule therapies like Janus kinase inhibitors, sphingosine-1-phosphate modulators, and Bruton's tyrosine kinase inhibitors are also discussed along with the various new topical medications. Newly approved topicals like phosphodiesterase-4 and JAK inhibitors are highlighted while also discussing the potential of tapinarof and emerging microbiome-targeted therapies. Beyond conventional approaches, the chapter touches upon unconventional therapies currently being studied. The goal of this chapter is to discuss new advances in AD treatment from medications in the initial stages of development to those nearing FDA approval.

Comparative effectiveness of tildrakizumab 200 mg versus tildrakizumab 100 mg in psoriatic patients with high disease burden or above 90 kg of body weight: a 16-week multicenter retrospective study - IL PSO (Italian landscape psoriasis).

PURPOSE: Tildrakizumab is a selective inhibitor of IL-23 approved for the treatment of moderate-to-severe plaque psoriasis in two dosages. We conducted a 16-week multicenter retrospective study to compare the effectiveness and safety of tildrakizumab 200 mg versus tildrakizumab 100 mg in patients with a high disease burden or high body weight. MATERIALS AND METHODS: Our retrospective study included 134 patients treated with tildrakizumab 200 mg and 364 patients treated with tildrakizumab 100 mg from 28 Italian Dermatology Units affected by moderate-to-severe plaque psoriasis. The patients had a body weight above 90 kg or a high disease burden (Psoriasis Area and Severity Index [PASI] ≥ 16 or the involvement of difficult-to-treat areas). We evaluated the effectiveness of tildrakizumab at the week-16 visit in terms of PASI90, PASI100 and absolute PASI ≤ 2. RESULTS: After 16 weeks of treatment with tildrakizumab 200 mg, PASI90 was reached by 57.5% of patients and PASI100 by 39.6% of patients. At the same time point, 34.3% and 24.2% of patients treated with tildrakizumab 100 mg achieved PASI90 and PASI100, respectively. CONCLUSIONS: Our data suggest that tildrakizumab 200 mg has better effectiveness than tildrakizumab 100 mg in patients with a body weight ≥ 90 kg and a high disease burden.

Isotretinoin's Effect on Fasting Lipid Profile in Acne Patients.

OBJECTIVE: To determine the isotretinoin's effect on fasting lipid profile in patients with acne. STUDY DESIGN: Observational study. Place and Duration of the Study: Outpatient Department of Dermatology, Dow International Medical College, Dow University of Health Sciences, Karachi, Pakistan, from 22nd June to 21st December 2022. METHODOLOGY: Patients of clinically moderate and severe acne were selected and prescribed a dose of 0.5mg /kg cap isotretinoin for 6 months. They were advised to get a fasting lipid profile at the baseline and then after two months of isotretinoin therapy. National Cancer Institute Common Terminology Criteria for Adverse Events v5.0 grading system and Adult Treatment Panel III were used for the grading of abnormalities. McNemar Bowker test was used to assess the difference in variables [serum triglycerides (TGs), cholesterol, high-density lipoproteins (HDL), and low-density lipoproteins (LDL)] at the baseline and after 2 months follow-up. RESULTS: A total of 214 patients were evaluated. After 2 months of isotretinoin therapy, TGs and cholesterol levels were elevated to higher grade in 2% of the patients. Likewise in 1% of patients, LDL levels rised to higher grade. Moreover, HDL levels declined to lower grade in 2% of the patients taking isotretinoin. CONCLUSION: Insignificant alterations in the various serum lipid parameters were observed in acne patients during isotretinoin therapy. It is advisable to obtain a baseline fasting lipid profile in all acne patients on isotretinoin and repeated in those with baseline abnormal levels and in patients with a clinical sign of metabolic syndrome and a family history of dyslipidemias. KEY WORDS: Acne, Hyperlipidemias, Isotretinoin, Laboratory monitoring.

The Psoriasis Treatment Pipeline: An Overview and Update.

Significant research advances in our understanding of psoriatic disease have led to the development of several highly selective, effective, and safe topical and systemic treatments. These treatments have led to unprecedented levels of disease clearance and control for most patients with psoriasis with cutaneous disease. However, there remains a need for improved treatments for those patients with recalcitrant disease, psoriatic arthritis, or nonplaque disease variants. Recently approved therapies and investigational products in ongoing clinical development programs that target IL-17A/F, IL-23, TYK2, PDE4, AhR or IL-36 cytokine signaling are improving the clinician's ability to care for a broader range of patients affected by psoriasis.

Biologics for Psoriasis.

Biologic therapies targeting tumor necrosis factor alpha (TNF-α) (infliximab, adalimumab, certolizumab, etanercept), the p40 subunit shared by IL-12 and IL-23 (ustekinumab), the p19 subunit of IL-23 (guselkumab, tildrakizumab, risankizumab), IL-17A (secukinumab, ixekizumab), IL-17-RA (brodalumab) and both IL-17A and IL-17F (bimekizumab) have revolutionized the treatment of psoriasis. In both the short and long term, risankizumab had highest Psoriasis Area and Severity Index 90 scores compared to other oral and injectable biologics. IL-23 inhibitors had lowest rates of short-term and long-term adverse events and most favorable long-term risk-benefit profile compared to IL-17, IL-12/23, and TNF-α inhibitors.

Evolving Landscape of Biologic Therapy for Pediatric Psoriasis.

Pediatric psoriasis is a chronic inflammatory skin condition. Current treatment modalities include topical medications, phototherapy, and systemic drugs, including biological agents. In cases of moderate-to-severe psoriasis recalcitrant to other therapies, biological therapies are often an attractive option given their dosing schedules, safety profiles, and need for less frequent laboratory monitoring, when compared with traditional systemic therapies. This article reviews biological treatment options approved for pediatric psoriasis and identifies others actively under investigation.

Oral Psoriasis Therapies.

Oral psoriasis therapies include both older traditional immunosuppressants, such as methotrexate, cyclosporine, and acitretin, as well as newer, more targeted agents, such as apremilast, deucravacitinib, and oral interleukin-23 receptor antagonists. Patients may prefer oral therapies to injectable therapies based on the route of administration. Both older and newer oral psoriasis therapies can be utilized effectively in the treatment of psoriasis. Here, we will review oral agents used in the treatment of psoriasis as well as provide commentary on their role in our current, evolving psoriasis treatment paradigm.

The Role of Genetics on Psoriasis Susceptibility, Comorbidities, and Treatment Response.

This review highlights advances made in psoriasis genetics, including findings from genome-wide association studies, exome-sequencing studies, and copy number variant studies. The impact of genetic variants on various comorbidities and therapeutic responses is discussed.

Treatment of Nail Psoriasis.

Nail psoriasis is associated with significant disease burden, negative impact on quality of life, and potential progression to psoriatic arthritis. Initiating timely and appropriate treatment is of the utmost importance, especially because nail disease may be more resistant to therapies than cutaneous psoriasis. This article reviews available intralesional, topical, and systemic treatment options for nail psoriasis, and discusses efficacy and safety of studied agents. Also reviewed are consensus treatment guideline recommendations. An updated algorithm to aid physicians in selection of specific treatment options is provided.

Adherence to Psoriasis Therapies.

Understanding the underlying causes of nonadherence among patients with psoriasis and adopting strategies to address these issues may allow providers to share responsibility and work alongside patients to overcome these barriers. The review explores patient adherence to different types of psoriasis treatment, suggestions for interventions to overcome barriers, and methods to promote adherence that have been published in the literature.

Analysis of factors influencing target PASI responses and side effects of methotrexate monotherapy in plaque psoriasis: a multicenter study of 1521 patients.

Methotrexate (MTX) is commonly used as first-line systemic treatment agent in psoriasis. We aimed to evaluate the clinical characteristics and treatment responses of patients with psoriasis undergoing MTX monotherapy. Data from adult patients with plaque psoriasis who received MTX monotherapy for at least 3 months between April 2012 and April 2022 were retrospectively evaluated in 19 tertiary care centers. Our study included 722 female and 799 male patients, a total of 1521 participants. The average age of the patients was 44.3 ± 15.5 years. Mode of treatment was oral in 20.4% of patients while in 79.4% it was subcutaneous. The median treatment duration was 8 months (IQR = 5-15). The median weekly dose was 15 mg (IQR = 11-15). 1448 (95.2%) patients were taking folic acid supplementation. At week 12, 16.3% of the patients achieved PASI (Psoriasis Area and Severity Index) 90 response while at week 24, 37.3% achieved it. Logistic regression analysis for week 12 identified the following independent factors affecting PASI 90 achievement positively: median weekly MTX dose ≤ 15 mg (P = 0.011), subcutaneous administration (P = 0.005), no prior systemic treatment (< 0.001) and folic acid use (0.021). In logistic regression analysis for week 24; median weekly MTX dose ≤ 15 mg (P = 0.001), baseline PASI ≥ 10 (P < 0.001), no prior systemic treatment (P < 0.004), folic acid use (P = 0.001) and absence of comorbidities (P = 0.009) were determined as independent factors affecting the achievement of PASI 90. Adverse effects were observed in 38.8% of the patients, with nausea/vomiting (23.9%) and transaminase elevation (13%) being the most common. The most common reasons for interruptions (15.3%) and discontinuations (27.1%) of the treatment were patient related individual factors. The use of MTX as the first systemic treatment agent, at doses ≤ 15 mg/week and concurrent folic acid application are positive predictive factors for achieving the target PASI response both at weeks 12 and 24. In our study, which is one of the most comprehensive studies on MTX treatment in psoriasis, we observed that MTX is an effective and safe treatment option.

Association of disease duration and PASI response rates at week 12 in patients with moderate-to-severe plaque psoriasis receiving biologics in the real-world psoriasis study of health outcomes (PSoHO).

PURPOSE: Currently, in the treatment of moderate-to-severe psoriasis (PsO) there is a lack of evidence demonstrating optimal biologic treatment response with respect to disease duration. The aim of this post-hoc analysis, using real world data from the Psoriasis Study of Health Outcomes (PSoHO), is to provide evidence if early intervention with biologics is associated with better treatment outcomes and if there is any difference among drug classes or individual biologics. MATERIALS AND METHODS: For this post-hoc analysis patients were categorised into two subgroups according to shorter (≤2 years) or longer (>2 years) disease duration. Analysis was performed on anti-interleukin (IL)-17A cohort vs other biologics cohort, anti-IL-17A vs other drug classes, and pairwise comparisons of ixekizumab vs individual biologics, provided that the statistical models converged. Analysis investigated the association of disease duration with the proportion of patients achieving 100% improvement in Psoriasis Area Severity Index score (PASI 100) at week 12. Adjusted comparative analyses, reported as odds ratio (OR), were performed using Frequentist Model Averaging (FMA) for each cohort or treatments within each subcategory of the subgroups. RESULTS: At week 12, anti-IL-17A and other biologics cohorts displayed minimal differences in numerical response rate for PASI 100 with respect to disease duration. The anti-IL-17A cohort showed a higher numerical PASI 100 response rate compared to the other biologic cohort irrespective of disease duration (≤2 years: 36.7% vs 21.8%; >2 years: 35.8% vs 21.9%). CONCLUSION: Overall, the results do not clearly indicate that treating patients early is critical in achieving optimal patient outcomes. Furthermore, patients treated with ixekizumab show numerically higher response rates relative to other individual biologics irrespective of disease duration.

Real-world use, perception, satisfaction, and adherence of calcipotriol and betamethasone dipropionate PAD-cream in patients with plaque psoriasis in Spain and Germany: results from a cross-sectional, online survey.

BACKGROUND: Psoriasis significantly impacts patients' quality of life (QoL). Dissatisfaction and non-adherence are major barriers associated with topical treatments. A cream based on the polyaphron dispersion (PAD) Technology containing a fixed-dose of calcipotriol (CAL) and betamethasone dipropionate (BDP) was designed for a patient-friendly psoriasis management. The CAL/BDP PAD-cream demonstrated efficacy, convenience, and safety/tolerability in clinical trials. OBJECTIVES: This research assesses the real-world use, perception, satisfaction, and adherence of CAL/BDP PAD-cream among plaque psoriasis patients. METHODS: Between September-November 2023, psoriasis patients from Spain and Germany using or having used CAL/BDP PAD-cream for >2 weeks were recruited via Wefight network to complete a 30-questions online survey. Anonymized results were pooled for descriptive statistical analysis. RESULTS: The survey was completed by 129 patients (mean age: 43 years; 66% females; mean psoriasis duration: 12 years). Most patients (93%) were satisfied with CAL/BDP PAD-cream. The 66% reported high adherence (visual analogue scale 80-100) and 91% preferred CAL/BDP PAD-cream to their previous topical(s). Patients highlighted its ease/convenience of application, tolerability, and lack of itching/burning. CONCLUSIONS: Psoriasis patients treated with CAL/BDP PAD-cream in a real-world setting show high satisfaction, good adherence, and a positive perception of the product, suggesting that favorable outcomes observed in clinical trials translate to real clinical practice.

Successful secukinumab treatment of generalized pustular psoriasis.

Generalized pustular psoriasis is a rare variant of psoriasis. Evidence recommending generalized pustular psoriasis treatment with secukinumab is limited. This report aims to evaluate the use of secukinumab in two patients with generalized pustular psoriasis. The standard treatment regimen for secukinumab was as follows: 300mg subcutaneously once weekly in weeks 0-4, followed by 300mg every four weeks. The efficacy was evaluated by analyzing the psoriasis area and severity index (PASI) and dermatology life quality index (DLQI). One patient had generalized pustular psoriasis, which had developed from palmoplantar pustulosis over 12 years. The second patient was an adolescent with recurrent generalized pustular psoriasis. The first patient achieved PASI-75 response by week 3 and both PASI-90 and a DLQI score of 0 were observed by week 8. The second patient achieved PASI-75 response by week 4 and complete clinical resolution, except for nail changes, and a DLQI of 0 by week 8, without any adverse events.

Effectiveness and safety of risankizumab in VEry severe plaque psoriasis: a real-life retrospective study (VESPA-Study).

BACKGROUND: The recent introduction of biological drugs specifically targeting the interleukins involved in psoriasis pathogenesis revolutionized the therapeutic scenario of moderate to severe forms of psoriasis. Among these, risankizumab, an anti-IL-23, was shown to be effective both in clinical trials and real-life experiences. However, data on its use on very severe forms of psoriasis, defined by a Psoriasis Area Severity Index (PASI) of at least 30, are scant. In this context, our study aimed to investigate the outcomes of patients with very severe psoriasis, and the involvement of difficult-to-treat areas treated with risankizumab for up to 2 years. METHODS: A retrospective, observational study enrolled patients with very severe plaque psoriasis and the involvement of difficult-to-treat areas undergoing treatment with risankizumab. Clinical and demographic data were collected at baseline. Moreover, at baseline and each dermatological examination (16, 28, 40 and 104 weeks), clinical improvement was measured using the percentage of patients achieving PASI 75/90/100 response, site-specific Psoriasis Global Assessment and Dermatology Life Quality Index. RESULTS: At baseline, the mean PASI was 35.1 ± 5.1. A significant reduction was observed since week 16 and maintained up to week 104. Moreover, the Psoriasis Global Assessment and Dermatology Life Quality Index improved as well. CONCLUSIONS: Risankizumab showed to be effective and safe in patients affected by very severe forms of psoriasis with the involvement of difficult-to-treat areas.

A randomized controlled double-blinded split-face prospective clinical trial to assess the efficacy, safety, and tolerability of a novel 3-step routine compared to benzoyl peroxide for the treatment of mild to moderate acne vulgaris.

Adult acne vulgaris affects up to 43-51% of individuals. While there are numerous treatment options for acne including topical, oral, and energy-based approaches, benzoyl peroxide (BPO) is a popular over the counter (OTC) treatment. Although BPO monotherapy has a long history of efficacy and safety, it suffers from several disadvantages, most notably, skin irritation, particularly for treatment naïve patients. In this prospective, randomized, controlled, split-face study, we evaluated the comparative efficacy, safety, and tolerability of a novel 3-step azelaic acid, salicylic acid, and graduated retinol regimen versus a common OTC BPO-based regimen over 12 weeks. A total of 37 adult subjects with self-reported mild to moderate acne vulgaris were recruited. A total of 21 subjects underwent a 2-week washout period and completed the full study with 3 dropping out due to product irritation from the BPO routine, and 13 being lost to follow-up. Detailed tolerability surveys were conducted at Week 4. Additional surveys on tolerability and product preferences were collected monthly, at Week 4, Week 8, and Week 12. A blinded board-certified dermatologist objectively scored the presence and type of acne lesions (open or closed comedones, papules, pustules, nodules, and cysts) at baseline, Week 4, Week 8, and Week 12. Patients photographed themselves and uploaded the images using personal mobile phones. Detailed Week 4 survey results showed across 25 domains of user-assessed product performance, the novel routine outperformed the BPO routine in 19 (76%) which included domains in preference (e.g. "I would use this in the future) and performance ("my skin improved" and "helped my acne clear up faster"). Users of the novel routine reported less facial redness, itching, and burning, though differences did not reach statistical significance. In terms of efficacy, both products performed similarly, reducing total acne lesions by 36% (novel routine) and 40% (BPO routine) by Week 12. Overall, accounting for user preferences and tolerability the novel routine was more preferred than the BPO routine in 79% of domains (22/28). Differences in objective acne lesion reduction were not statistically significant (p = 0.97). In a randomized split-face study, a 3-step azelaic acid, salicylic acid, and graduated retinol regimen delivered similar acne lesion reduction, fewer user dropouts, greater user tolerability, and higher use preference compared to a 3-step BPO routine based in a cohort of participants with mild-to-moderate acne vulgaris.
