A severe psoriasis flare after COVID-19 treated with risankizumab: complete skin clearance after 16 weeks.

The development of flares or new-onset of immune-mediated dermatologic diseases, including psoriasis, has occurred with the worldwide spreading of the COVID-19 pandemic. We report the case of a 38-year-old woman who came to our department with a severe flare of plaque psoriasis four weeks after SARS-CoV-2 infection. Her Psoriasis Area Severity Index was 25, and her Dermatology Life Quality Index was 18. Our initial decision was to prescribe acitretin, but the patients reported adverse events. For this reason, we started risankizumab with complete skin clearance after 16 weeks. The patient is still on treatment, and no adverse events have been reported to date.

Baseline Characteristics and mNAPSI Change from Baseline Scores Through Month 12 for Patients with Moderate-to-Severe Plaque Psoriasis and Concomitant Nail Psoriasis Treated with Biologics from PSoHO.

INTRODUCTION: Nail psoriasis is highly prevalent among patients with psoriasis yet remains one of the most challenging areas to treat. To better understand the treatment landscape for psoriatic nail disease, more studies are needed that compare the effectiveness of different biologics for patients with nail psoriasis. This study contributes to this objective by directly comparing the effectiveness of approved biologics in improving nail psoriasis for patients up to month 12 in a real-world setting. METHODS: Psoriasis Study of Health Outcomes (PSoHO) is an ongoing 3-year, prospective, non-interventional cohort study of adults with chronic moderate-to-severe plaque psoriasis initiating or switching to a new biologic. This study assessed the change in modified Nail Psoriasis Severity Index (mNAPSI) score from baseline to months 3, 6 and 12 for 763 patients and compared the effectiveness of anti-interleukin (IL)-17A biologics versus other approved biologics, as well as ixekizumab versus secukinumab, guselkumab, risankizumab and adalimumab. Comparative adjusted analyses used frequentist model averaging (FMA). Least square mean difference (LSMD) in mNAPSI scores are presented as observed. RESULTS: Irrespective of the severity of nail psoriasis at baseline, the anti-IL-17A cohort had greater mean mNAPSI reductions from baseline compared to the other biologics cohort through month 12, reaching significance at months 3 and 6 in the adjusted analysis. For patients with moderate-to-severe nail psoriasis, ixekizumab showed numerically higher mean reductions in mNAPSI scores compared to all other studied biologics, reaching significance versus guselkumab at all timepoints and risankizumab at month 6. CONCLUSION: This real-world study showed that patients with moderate-to-severe psoriasis and any severity of concomitant nail involvement had significantly faster and more substantial improvements in nail psoriasis up to month 6 in the anti-IL-17A cohort compared to the other biologics cohort. Of the individual biologics studied, ixekizumab showed the highest numerical improvements in nail psoriasis at month 12. TRIAL REGISTRATION: EUPAS24207.

Management of Patients Affected by Moderate-to-Severe Atopic Dermatitis with JAK Inhibitors in Real-World Clinical Practice: An Italian Delphi Consensus.

INTRODUCTION: Several systemic therapies have been approved for the treatment of severe AD. In particular, Janus kinase inhibitors (JAKi), including abrocitinib, baricitinib, and upadacitinib, recently received approval for the treatment of patients with severe AD after being evaluated in several clinical trials. However, a few concerns have been raised regarding their long-term safety and the management of these drugs in real-world clinical practice. In this article we described the results of a Delphi consensus aimed at describing the knowledge on JAKi and focusing, in particular, on providing clinical recommendations for dermatologists in daily practice regarding the use of these drugs. METHODS: Twelve Italian dermatologists reviewed the most recent literature regarding the efficacy and safety profiles of JAKi and proposed 24 statements. RESULTS: Agreement was reached for statements focusing on three main topics: (1) place in therapy of JAKi in patients with moderate-to-severe AD; (2) effectiveness and safety of JAK inhibitors in different phenotypes; (3) different approaches to the management of patients treated with JAKi in clinical practice. The panel proposed several recommendations regarding all the statements. CONCLUSION: Given the wide use of JAKi in clinical practice, it is crucial to establish a specific follow-up for each patient's phenotype in order to achieve the best possible clinical outcome and minimize potential adverse events.

Practical Use of Upadacitinib in Patients with Severe Atopic Dermatitis in a Real-World Setting: A Systematic Review.

Upadacitinib is a selective Janus kinase inhibitor approved for the treatment of severe atopic dermatitis (AD). This systematic review aims to summarize the most recent data in terms of effectiveness and safety of upadacitinib in the treatment of severe AD in a real-world setting. The review included a comprehensive search of databases, including PubMed, Google Scholar and Web of Science, according to Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. The literature search initially identified 242 studies. Of these, 214 were excluded after reviewing their titles and abstracts. We then conducted a full-text review of 25 studies, of which 17 met our inclusion criteria and were therefore included in our systematic review. The analysis of real-world studies showed high effectiveness of upadacitinib, in terms of both clinical signs and subjective symptoms, in different patient populations, including those resistant to other treatments. No new significant safety concerns have emerged as compared to randomized clinical trials.

Bimekizumab for the Treatment of Plaque Psoriasis With Involvement of Genitalia: A 16-Week Multicenter Real-World Experience - IL PSO (Italian Landscape Psoriasis).

INTRODUCTION: Genital involvement is observed in approximately 60% of patients with psoriasis, presenting clinicians with formidable challenges in treatment. While new biologic drugs have emerged as safe and effective options for managing psoriasis, their efficacy in challenging-to-treat areas remains inadequately explored. Intriguingly, studies have shown that interleukin (IL)-17 inhibitors exhibit effectiveness in addressing genital psoriasis. OBJECTIVES: We aimed to determine the effectiveness profile of bimekizumab in patients affected by moderate-to-severe plaque psoriasis with involvement of genitalia. METHODS: Bimekizumab, a dual inhibitor of both IL-17A and IL-17F, was the focus of our 16-week study, demonstrating highly favorable outcomes for patients with genital psoriasis. The effectiveness of bimekizumab was evaluated in terms of improvement in Static Physician's Global Assessment of Genitalia (sPGA-G) and Psoriasis Area and Severity Index. RESULTS: Sixty-five adult patients were enrolled. Remarkably, 98.4% of our participants achieved a clear sPGA-G score (s-PGA-g=0) within 16 weeks. Moreover, consistent improvements were observed in PASI scores, accompanied by a significant reduction in the mean Dermatology Life Quality Index (DLQI), signifying enhanced quality of life. Notably, none of the patients reported a severe impairment in their quality of life after 16 weeks of treatment. In our cohort of 65 patients, subgroup analyses unveiled that the effectiveness of bimekizumab remained unaffected by prior exposure to other biologics or by obesity. CONCLUSIONS: Our initial findings suggest that bimekizumab may serve as a valuable treatment option for genital psoriasis. Nevertheless, further research with larger sample sizes and longer-term follow-up is imperative to conclusively validate these results.

Effectiveness and Safety of Biological Therapies in Very Severe Plaque Psoriasis: A Real-Life Retrospective Study.

Psoriasis can have a significant impact on quality of life and productivity, especially with increased severity. However, there is limited evidence on biologics' efficacy in highly severe cases compared to moderate-to-severe ones. This study aimed to evaluate the effectiveness and safety of novel biological therapies in very severe psoriasis. We conducted a retrospective analysis on patients ≥ 18 years old affected by very severe psoriasis who had received a biological agent for at least 16 weeks. We used PASI to assess disease severity and effectiveness at weeks 16, 52, 104, and 156. Safety was evaluated by tracking treatment discontinuation rates and adverse events. This study included 29 males and 11 females, with a mean age of 55.80 years (SD 13.82). Cardiometabolic diseases were the most common comorbidities (25.00%). Twenty-eight (70.00%) patients had psoriasis involvement in at least one difficult-to-treat area. All patients completed 16 weeks of treatment. The mean PASI was 31.60 (SD 2.57) at baseline, 3.48 (SD 4.13) at week 16, 0.58 (SD 1.70) at week 52, 0.77 (SD 1.66) at week 104, and 1.29 (SD 2.12) at week 156. PASI90 and 100 were achieved by 52.50% and 30.00% of patients at week 16, by 96.15% and 80.77% at week 52, by 93.33% and 66.67% at week 104, and by 85.71% and 42.86% at week 156. PASIs ≤ 2 were achieved by 50.00% of patients at week 16, 88.46% at week 52, 86.67% at week 104, and 85.71% at week 156. Only two patients discontinued biologics due to complete remission, and mild AEs were reported by four patients. Our findings show that biologics are effective and well tolerated for treating very severe psoriasis, maintaining long-term effectiveness.

Effectiveness, Tolerability, and Drug Survival of Risankizumab in a Real-World Setting: A Three-Year Retrospective Multicenter Study-IL PSO (ITALIAN LANDSCAPE PSORIASIS).

BACKGROUND: Risankizumab is a humanized monoclonal antibody that selectively inhibits interleukin-23. It has been approved for moderate-to-severe plaque psoriasis and has shown efficacy and safety in clinical trials and real-world experiences. This study aimed to evaluate the long-term effectiveness, safety, and drug survival of risankizumab in a real-life setting. MATERIALS AND METHODS: We included patients treated with risankizumab from January 2019 to February 2023. A Psoriasis Area and Severity Index score (PASI) was collected at weeks 0, 16, 28, 52, 104, and 156, when available. The occurrence of any adverse events was recorded at each visit. RESULTS: We enrolled 1047 patients. At week 52, a ≥90% improvement in PASI was observed in 81.44% of patients, with a continuous improvement throughout the study (88.99% and 99.07% at weeks 104 and 156, respectively). After three years of treatment, all patients involving the scalp, palms/soles, and genitalia and 95% of patients with nail psoriasis achieved a complete or almost complete skin clearance. No significant safety findings were observed, and 90.73% of the patients were still on treatment after 36 months. CONCLUSIONS: This study supports the long-term effectiveness and safety of risankizumab in a real-world setting, even in patients involving difficult-to-treat areas.

Effectiveness of ixekizumab for the treatment of moderate-to-severe plaque psoriasis with involvement of difficult-to-treat areas: A 52-week multicenter retrospective study.

Biological drugs have dramatically changed the approach to treating moderate-to-severe plaque psoriasis, achieving excellent skin clearance and safety outcomes. However, the management of difficult-to-treat areas (e.g., scalp, palms/soles, nails, and genitalia) still represents a challenge in psoriasis treatment. Data in the literature on difficult-to-treat sites are limited and, frequently, no specific analysis is performed during clinical trials. We conducted a 52-week, retrospective study to evaluate the effectiveness of ixekizumab in 120 patients with moderate-to-severe plaque psoriasis of at least one difficult-to-treat area (scalp, palmoplantar surfaces, nails, and genitalia). Ninety-nine patients had scalp psoriasis, 35 had involvement of the palms or soles, 27 were affected by genital psoriasis, and 22 patients reported involvement of the nails. After 1 year of treatment, 96% of patients with scalp involvement, 95.6% of patients with palmoplantar psoriasis, 95.2% of patients with genital psoriasis, and 85% of patients with nail involvement achieved a site-specific Physician's Global Assessment of 0 or 1 (clear or almost clear). No serious adverse events were observed during the study. Our study supports the effectiveness of ixekizumab in plaque psoriasis involving difficult-to-treat sites.

Association between maternal dupilumab exposure and pregnancy outcomes in patients with moderate-to-severe atopic dermatitis: A nationwide retrospective cohort study.

BACKGROUND: There is limited epidemiological evidence on outcomes associated with dupilumab exposure during pregnancy; monitoring pregnancy outcomes in large populations is required. OBJECTIVE: To investigate the potential association between exposure to dupilumab in pregnant women with atopic dermatitis and any adverse pregnancy, neonatal, congenital and post-partum outcomes. METHODS: We performed a multicentre retrospective cohort study across 19 Italian tertiary referral hospital. Childbearing women were eligible if aged 18-49 years and carried out the pregnancy between 1 October 2018 and 1 September 2022. RESULTS: We retrospectively screened records of 5062 patients receiving dupilumab regardless of age and gender, identifying 951 female atopic dermatitis patients of childbearing age, 29 of whom had been exposed to the drug during pregnancy (3%). The median duration of dupilumab treatment prior to conception was 22.5 weeks (range: 3-118). The median time of exposure to the drug during pregnancy was 6 weeks (range: 2-24). All the documented pregnancies were unplanned, and the drug was discontinued in all cases once pregnancy status was reported. The comparison of the study cohort and the control group found no significant drug-associated risk for adverse pregnancy, congenital, neonatal or post-partum outcomes. The absence of a statistically significant effect of exposure on the event was confirmed by bivariate analysis and multivariate analysis adjusted for other confounding factors. CONCLUSIONS: This cohort of pregnant patients exposed to dupilumab adds to the existing evidence concerning the safety of biologic agents in pregnancy. No safety issues were identified regarding the primary outcome assessed. In clinical practice, these data provide reassurance in case of dupilumab exposure during the first trimester. However, the continuous use of dupilumab throughout pregnancy warrants further research.

Bone marrow metastases: a systematic review of a neglected involvement in malignant melanoma.

The occurrence of bone marrow metastases (BMM) in melanoma patients is often underestimated, with only 7% detected during in-vivo staging procedures but rising to 45% in autopsy cases. This systematic review aims to shed light on the clinical and laboratory features of BMM in melanoma by analyzing 73 studies selected from 2 482 initially retrieved from PubMed, Embase , and Cochrane CENTRAL databases. Our findings reveal a slight male predominance, with a median age at BMM diagnosis of 56 years. Primary melanoma sites included the skin (52%), mucosa (8.8%), uvea (20.5%) and unidentified (19%). BMM was preceded by lymph node involvement in 36.5% of cases, whereas 63% showed no nodal metastases, with direct BMM occurring in 22.5% and metastases to other sites in 41%. Common BMM symptoms included pain (60.7%), anemia (80%), thrombocytopenia, leukoerythroblastosis, pancytopenia and leukopenia, while disseminated intravascular coagulation was detected in 11% of cases. In 23.6% of cases, BMM was amelanotic. The prognosis for BMM is grim, with a median survival of only 2 months. Conventional therapies for BMM remain largely ineffective, emphasizing the importance of considering bone marrow as a potential metastatic site in melanoma patients.

Effectiveness and safety of risankizumab in HIV patients with psoriasis: A case series.

Biological therapies represent the gold-standard treatment of severe forms of plaque psoriasis. However, people living with HIV are often under-treated for psoriasis because very limited data are available on the use of biologics in this population. We report four cases of patients affected by HIV and moderate-to-severe plaque psoriasis, all treated with risankizumab, a monoclonal antibody that selectively targets interleukin-23. After 16 weeks, all patients experienced complete or almost complete skin clearance without any adverse events. Data on the effectiveness and safety of biological therapies in people living with HIV are limited to case reports or small case series, especially for the most recently approved inhibitors of interleukin-23. Our experienced, although limited, supports the role of risankizumab as a safe and effective therapy for psoriasis amongst patients living with HIV.

Guselkumab-Treated Patients with Plaque Psoriasis Who Achieved Complete Skin Clearance for ≥ 156 Consecutive Weeks: A Post-Hoc Analysis From the VOYAGE 1 Clinical Trial.

BACKGROUND: Treatment of moderate-to-severe plaque psoriasis with biologics, such as guselkumab, has demonstrated greater efficacy over traditional non-biologic treatments. However, given patient diversity, greater understanding of the relationship between patient characteristics, positive clinical outcomes, and long-term response to biologics is crucial for optimizing treatment choices. MATERIALS AND METHODS: This post-hoc analysis of the 5-year VOYAGE 1 clinical trial compares baseline characteristics of patients maintaining a Psoriasis Area and Severity Index (PASI) score of 0 at all visits for ≥ 156 consecutive weeks (PASI = 0 group) with those that never achieve PASI = 0 (comparator group), using descriptive statistics and a multiple logistic regression model. Guselkumab plasma trough concentrations in both response groups were assessed from Weeks 4-156. RESULTS: Of patients who started guselkumab treatment at Week 0 or at Week 16 after switching from placebo, 22.7% (112/494) maintained PASI = 0 for ≥ 156 consecutive weeks. Numerical differences in baseline characteristics, including age, obesity, diabetes, PASI score, disease duration, smoking status, and psoriatic arthritis comorbidity, were identified between the PASI = 0 group and comparator group. Plasma guselkumab levels were consistently higher in the PASI = 0 group. Multiple logistic regression analysis revealed absence of diabetes, lower Dermatology Life Quality Index score at baseline, and higher Week 4 guselkumab plasma concentration as significantly (p < 0.05) associated with the PASI = 0 group. CONCLUSION: A substantial (22.7%) number of guselkumab-treated patients in the VOYAGE 1 clinical trial maintained complete skin clearance for a consecutive period of ≥ 156 weeks. Factors associated with this outcome may suggest clinical benefits of holistic treatment approaches. TRIAL REGISTRATION: NCT02207231.

Implementation of regulatory guidance for JAK inhibitors use in patients with immune-mediated inflammatory diseases: An international appropriateness study.

BACKGROUND AND AIMS: The Pharmacovigilance Risk Assessment Committee (PRAC) proposed measures to address severe side effects linked to Janus kinase inhibitors (JAKi) in immune-mediated inflammatory diseases (IMID). Use of these medications in individuals aged 65 and older, those at high cardiovascular risk, active or former long-term smokers, and those with increased cancer risk should be considered only if no alternatives exist. Caution is advised when administering JAKi to patients at risk of venous thromboembolism. We aim to implement recommendations from regulatory guidelines based on areas of uncertainty identified. METHODS: A two-round modified Research and Development/University of California Los Angeles appropriateness methodology study was conducted. A panel of 21 gastroenterologists, dermatologists and rheumatologists used a 9-point Likert scale to rate the appropriateness of administering a JAKi for each proposed clinical scenario. Scores for appropriateness were categorized as appropriate, uncertain, or inappropriate. Two rounds were performed, each with online surveys and a virtual meeting to enable discussion and rating of each best practice. RESULTS: Round 1 involved participants rating JAKi appropriateness and suggesting descriptors to reduce uncertainty. Survey results were discussed in a virtual meeting, identifying areas of disagreement. In round 2, participants rated their agreement with descriptors from round 1, and the level of uncertainty and disagreement reduced. Age flexibility is recommended in the absence of other risk factors. Active counseling on modifiable risks (e.g., overweight, mild hyperlipidemia and hypertension) and smoking cessation is advised. Uncertainty persists regarding cancer risk due to various factors. CONCLUSIONS: We outlined regulatory guidance without a personalized evaluation of the patient's risk profile might lead to uncertainty and become an arid technicality. Therefore, we identified gaps and implemented PRAC recommendations to help health professionals in clinical practice.

Anti-interleukin-17 and anti-interleukin-23 biologic drugs for genital psoriasis: a single-center retrospective comparative study.

Genital psoriasis affects 3-33% of patients with psoriasis during the course of the disease, usually leading to a severe reduction in the patient's quality of life. This study aims to retrospectively assess the effectiveness of interleukin (IL)-23 and IL-17 inhibitors in a real-life population affected by moderate-to-severe plaque psoriasis with genital involvement coming from our dermatology department. A total of 86 patients with a diagnosis of moderate-tosevere plaque psoriasis with severe genital involvement were enrolled. Patient characteristics, psoriasis area and severity index (PASI), and static physician global assessment of genitalia (sPGAG) at each visit were recorded. During the treatment, the mean PASI decreased from 12.8 to 0.63 at week 52; a PGA of 0/1 was reached by 97.40% at week 52 and by 100% of patients (37/37) at week 104. No significant differences between IL-23 and IL-17 inhibitors were observed; indeed, the bio-naïve group of patients demonstrated a superior response compared to the group of bioexperienced patients.Our findings confirmed that IL-23 and IL-17 inhibitors are safe and effective therapeutic options for the treatment of genital psoriasis.
