Psoriasis with Leg Involvement as the New Difficult-To-Treat Area: A Cohort Study of Patients Treated With Risankizumab.

INTRODUCTION: Historically, difficult-to-treat areas in psoriasis included face, scalp, folds, genitalia, nails, and palmoplantar region. Recent studies have found that lower limbs behave like a "new" difficult-to-treat area as they can be the only site of residual disease even in patients undergoing biologic therapies. OBJECTIVES: We aimed to evaluate whether legs had different response rates and response times to treatment with a new biologic drug, risankizumab, compared to other body sites. METHODS: We conducted a real-life, observational, retrospective, multicenter study including patients affected by moderate-to-severe psoriasis with leg involvement and undergoing biological therapy with risankizumab for more than 16 weeks. The Psoriasis Area Severity Index (PASI) and Leg-PASI were collected at T0 and at weeks 16, 28, 40, 52, 64, and 76. Statistical analysis using Student's t test and linear regression analysis were performed. RESULTS: A total of 124 patients were included. The difference between the improvement percentage compared to baseline was statistically significant at weeks 16 and 28, demonstrating that Leg-PASI improved less than PASI. From the linear regression it was deduced that the slope is statistically less steep for Leg-PASI than for overall PASI, confirming that this site responds more slowly to the therapy. CONCLUSIONS: Leg response to risankizumab appears to differ significantly from other body sites in the first weeks of treatment, even if after 28 weeks, statistical significance is lost. Our preliminary finding suggests that risankizumab can be considered an effective treatment for leg psoriasis but with longer response times than other areas, demonstrating the relative nature of resistance to treatment of this district.

Guselkumab for the treatment of psoriasis: a 60-week real-life multicenter retrospective experience.

BACKGROUND: Real-world data for guselkumab, the first interleukin-23 inhibitor approved to treat moderate-to-severe psoriasis, are scarce. This study represents the first 60-week, real-life, multicenter, retrospective experience to investigate the effectiveness, safety, tolerability, and drug retention of guselkumab in psoriatic patients. RESEARCH DESIGN AND METHODS: Clinical information was collected at baseline and at weeks 12, 24, 36, 48, and 60. RESULTS: The mean baseline Psoriasis Activity Severity Index (PASI) reduced from 14.2 to 3.1 at week 12 and decreased to around 0 at weeks 36, 48, and 60. PASI 75, PASI 90, and PASI 100 were 100%, 96.8%, and 83.9% at week 60, respectively. Multiple logistic regression analysis showed that neither body mass index >30, smoking, ≥3 comorbidities, difficult-to-treat areas, nor a failure to ≥2 prior biologic treatments significantly influenced PASI reduction (p > 0.05). CONCLUSIONS: Our findings confirm guselkumab as an appropriate therapeutic option in routine clinical practice, especially when dealing with complex patients with comorbidities or previous failure to biologic treatments.

Assessment of the perceived burden associated with Malignant Melanoma with Pictorial Representation of Illness and Self Measure (PRISM) and Melanoma Concerns Questionnaire (MCQ-28).

PURPOSE: The impact of malignant melanoma (MM) on patients' psychophysical well-being has been poorly addressed. We aimed to assess the perceived burden in patients with a diagnosis of MM, using two different tools, one generic and one specific for MM, such as Pictorial Representation of Illness and Self Measure (PRISM) and Melanoma Concerns Questionnaire (MCQ-28), respectively. The correlation between PRISM and MCQ-28 subscales and the relevance of disease and patient-related variables were also investigated. METHODS: This single-centre, cross-sectional study included all adult consecutive MM patients who attended our Dermatology Unit from December 2020 to June 2021. Demographics and disease-related data were recorded. PRISM and MCQ-28 were administered. RESULTS: One hundred and seventy-one patients were included (mean age: 59.5 ±14.9 years.; 48.0% males). Median time from MM diagnosis to inclusion was 36 months. Nearly 80% of the patients had in situ or stage I MM. Overall, 22.2% of the patients reported a PRISM score <100mm and similar percentages provided scores indicating impaired quality of life, as assessed with MCQ-28 subscales. A weak, albeit significant, correlation was found between PRISM scores and ACP, CON and SOC2 subscales. The most relevant association found was that between lower PRISM scores and higher-stage MM. CONCLUSIONS: In the study population, mostly affected with superficial MM, their perception of the burden associated with MM did not appear either particularly dramatic or disabling. PRISM seems a reliable system for capturing and quantifying the domains correlated with the emotive dimension of MM, especially MM-related concerns and willingness to face life.

Use of Apremilast® in the psoriasis treatment: a real-life multicenter Italian experience.

BACKGROUND: Apremilast® (Amgen, Thousand Oaks, CA, USA) is the first small molecule approved for the treatment of moderate-to-severe psoriasis in adult patients; however, real-life data are still limited. We investigated the effectiveness and safety of this drug in a multicenter real-world setting. METHODS: We retrospectively reviewed data from all psoriatic patients who received at least one dose of Apremilast® (Amgen) and collected demographic data and medical history at baseline and periodically for 36 months. RESULTS: A total of 111 patients entered in the study. The mean drug survival duration was 21.8±10.6 months; however, it was significantly shorter when comorbidities were ≥3 and if biologic drugs were previously administered. ΔPASI90 was achieved in 29% of patients and ΔPASI50 in 68% at T4; the rate of ΔPASI improvement increased progressively at T12, T24, T36 in patients who continued to receive Apremilast® (Amgen). At the end of the study 50 patients discontinued the treatment because of adverse events (19.8%), primary failure (19%) or secondary failure (6.3%). CONCLUSIONS: Apremilast® (Amgen) proved to be an effective, safe, and manageable drug, showing effectiveness also in difficult-to-treat patients with psoriasis, with a favorable tolerability profile and a potentially valid weight loss effect. We believe that treating patients with few comorbidities who are naive to biological therapy may result in higher response rates and longer mean drug survival.
