Introduction: To investigate the efficacy and safety of Cutegel^® MAX (Cutegel) in the correction of moderate-to-severe nasolabial folds (NLFS) compared to Restylane^® (Restylane, control).

Methods: This study was a 52-week, multicenter, randomized, double-blinded, active-controlled clinical trial. Qualified participants with moderate-to-severe NLFs were randomly assigned in a 1:1 ratio to receive Cutegel or Restylane. For the primary efficacy endpoint, the response rate was defined as the percentage of subjects exhibiting an improvement of at least one-point based on blinded evaluation of Wrinkle Severity Rating Scale (WSRS) at 24 weeks after injection. Other secondary efficacy endpoints and treatment-emergent adverse events (TEAEs) were assessed.

Results: Of 340 subjects randomized, 317 completed the week 52 visit. In the per protocol set (PPS), the blinded evaluator-assessed response rates at week 24 were 81.17% for Cutegel versus 77.56% for Restylane (p =  0.327). The between-group treatment differences in response rates were 3.60% [95% confidence interval (CI) = (-5.39%, 12.60%)], which demonstrated the noninferiority of Cutegel. Other secondary efficacy endpoints supported this. No significant differences were observed in the occurrence of adverse events between the two groups.

Conclusion: Similar to Restylane, Cutegel was effective and well tolerated in correcting moderate-to-severe NLFs among the Chinese population.

Background: Genital involvement in atopic dermatitis(AD) can have a significant impact on the patient's quality of life. However, inspection of genital areas is not usually conducted during routine examination and patients may be reluctant to inform the clinician or show this area.

Objective: to evaluate the efficacy of tralokinumab in AD patients with genital involvement.

Methods: Adult patients with moderate/severe AD and genital involvement receiving tralokinumab have been analyzed. Primary endpoints were EASI, DLQI, PP-NRS, genital-IGA (g-IGA) and genital itching (GI) at week 16.

Results: out of 48 patients with moderate/severe AD under treatment with tralokinumab, 12 patients (25%) showed a genital involvement. Seven patients reported itching in the genital area (58%), while none reported a positive history of genital infections. Median scores at T0 were EASI 17.5, PP-NRS 8 and DLQI 14. After 16 weeks of treatment, we observed a median EASI of 3, a median PP-NRS of 1 and a median DLQI of 1. Finally, concerning the genital response, after 16 weeks of treatment, we observed a statistically significant decrease in mean GI and g-IGA scores.

Conclusion: despite the small size of our sample, tralokinumab can be considered as a valid treatment option for AD with genital involvement.

Background: Biologics have revolutionized psoriasis treatment; however, relapse of psoriasis after discontinuation of biologics remains unresolved.

Objective: To assess the impact of adjunctive Chinese medicine (CM) therapy on relapse of psoriasis vulgaris (PV) after discontinuation of biologics.

Methods: We constructed a prospective cohort study through a psoriasis case registry platform that enrolled patients treated with biologics (in combination with or without CM). The endpoint event was relapse, defined as loss of psoriasis area and severity index (PASI) 75.

Results: A total of 391 patients completed the study and were included in the analysis, of whom 169 (43.2%) experienced relapse during follow-up. To minimize the bias, a 1:1 propensity score matching (PSM) was performed, generating matched cohorts of 156 individuals per group. Adjuvant CM therapy significantly associated with reduced incidence of relapse (HR =0.418, 95% CI = 0.289 ∼ 0.604, p < 0.001), and the protective effect of CM in the subgroup analysis was significant. In addition, PASI 90 response and disease duration were associated with relapse (p < 0.05).

Conclusion: Adjunctive CM therapy is associated with reduced relapse incidence in PV after discontinuation of biologics.

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.

Purpose: Trichodysplasia spinulosa (TS) is a rare, disfiguring skin condition which presents with widespread asymptomatic or pruritic, skin-colored papules with white protruding keratin spiculations in immunocompromised individuals. Due to its rarity, there is little data to guide treatment decisions. The purpose of this article is to report a case of TS that completely resolved after treatment with topical cidofovir.Materials and methods: A 19-year-old immunosuppressed female presented with widespread painful, itchy bumps on the nose and face. Upon examination, there were erythematous papules with hyperkeratinized spicules affecting the central face. Biopsy of the lesions was consistent with TS which was confirmed via PCR analysis. The tenderness of this patient's eruption was highly atypical for TS. Once daily topical application of compounded 1% cidofovir cream was prescribed.Results: The patient's symptoms resolved completely after 4 weeks of therapy with topical cidofovir 1% cream, without reduction of immunosuppression.Conclusions: Topical cidofovir 1% cream may be a valuable treatment for this rare disease.

Background: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease. Most patients with moderate-to-severe disease require long-term antibiotic treatment, or biologic treatments to control their disease. Despite these interventions, relapses are common. This study evaluated the effectiveness of piperacillin/tazobactam treatment in patients with Hurley stage II and III HS who experienced disease flares and did not respond to conventional antibiotic and biologic treatment. Methods: Patients with HS hospitalized at the Department of Dermatology, Sheba Medical Center between August 2021 and January 2023 were retrospectively analyzed. Results: A cohort of ten such patients were treated with piperacillin/tazobactam for 6-21 days. Eight (80%) and two (20%) patients respectively demonstrated 2- and 1-grade improvements, from their baseline HS-Physician Global Assessment score. During the follow-up period, nine patients were monitored. HS Clinical Response (HiSCR) was achieved in six (66.7%) and five (55.6%) patients at the 3- and 6-month follow-up visits, respectively. Conclusions: In conclusion, Piperacillin/tazobactam emerges as a promising therapeutic option for disease flare-up in patients with Hurley stage II and III HS who do not respond to conventional treatment. Thus, piperacillin/tazobactam should be considered as crisis therapy for this patient subset.
