Long-term drug survival of risankizumab in psoriasis: insights from a real-life multicenter study on hard-to-treat areas.

Psoriasis, a chronic inflammatory condition, often presents challenges in treatment, particularly in areas such as nails, palms/soles, scalp/face, and genitalia. Monoclonal antibodies (mAb) like risankizumab targeting interleukin-23 (IL-23) have emerged as promising treatments, yet data on long-term efficacy remain limited. This multicenter retrospective study aimed to evaluate the drug survival at 12 and 36 months of 191 psoriasis patients treated with risankizumab, focusing on critical areas. Patients, previously unresponsive to first-line therapies, were treated according to Italian Guidelines. Survival analysis revealed a 97.6% one-year and 95% three-year drug survival rate. Secondary ineffectiveness was the primary reason for discontinuation, particularly in palmoplantar involvement cases. Factors such as BMI, gender, age, disease duration, baseline severity, and previous biologic exposure did not significantly impact drug survival, except for palmoplantar psoriasis (HR 4.72). Risankizumab demonstrated prolonged response with low treatment switch requirements, especially notable in challenging areas. Understanding such factors can aid in optimizing therapeutic approaches for improved patient care and long-term outcomes in managing psoriasis. Further research is warranted to refine treatment strategies in difficult-to-treat areas.

Moderate-to-severe atopic dermatitis in adolescents treated with dupilumab: A multicentre Italian real-world experience.

BACKGROUND: Moderate-to-severe atopic dermatitis (AD) in the adolescence is a high burden disease, and its treatment can be very challenging due to paucity of approved systemic drugs for this age and their side-effects. Dupilumab was recently approved for treatment of adolescent AD. OBJECTIVES: A multicentre, prospective, real-world study on the effectiveness and safety of dupilumab in adolescents (aged from ≥12 to <18 years) with moderate-to-severe AD was conducted. The main AD clinical phenotypes were also examined. METHODS: Data of adolescents with moderate-to-severe AD treated with dupilumab at label dosage for 16 weeks were collected. Treatment outcome was assessed by EASI, NRS itch, NRS sleep loss and CDLQI scores at baseline and after 16 weeks of treatment. The clinical scores were also evaluated according to clinical phenotypes. RESULTS: One hundred and thirty-nine adolescents were enrolled in the study. Flexural eczema and head and neck eczema were the most frequent clinical phenotypes, followed by hand eczema and portrait-like dermatitis. Coexistence of more than 1 phenotype was documented in 126/139 (88.5%) adolescents. Three patients (2.1%) contracted asymptomatic SARS-CoV-2 infection and 1 of the discontinued dupilumab treatment before the target treatment period. A significant improvement in EASI, NRS itch, NRS sleep loss and CDLQI was observed after 16 weeks of treatment with dupilumab. This outcome was better than that observed in clinical trials. Dupilumab resulted effective in all AD phenotypes, especially in diffuse eczema. Twenty-eight (20.1%) patients reported adverse events, conjunctivitis and flushing being the most frequent. None of patients discontinued dupilumab due to adverse event. CONCLUSIONS: Dupilumab in adolescent AD showed excellent effectiveness at week 16 with consistent improvement of all clinical scores. Moreover, dupilumab showed a good safety profile also in this COVID-19 pandemic era.

Clinical efficacy of two topical corticosteroids in the management of chronic hand eczema.

AIM: The aim of this study was to evaluate efficacy, tolerability and safety of a combination treatment with fluticasone propionate 0.05% cream and clobetasole ointment 0.05% in patients suffering from chronic hand eczema. METHODS: The study examined 30 patients with a clinical diagnosis of chronic hand eczema. RESULTS: The treatment with topical corticosteroids resulted effective and topical corticosteroids proved their efficacy in mild and moderate hand eczema. CONCLUSION: In according to the severity of the disease, authors suggest two different clinical strategies in the management of hand eczema.

Gluten-free diet as a therapeutic approach in psoriatic patients: if yes, when.

Since most of the studies are mainly confined to cases reporting coincidence of psoriasis and celiac disease, the authors want to underline the utility of investigating the possible presence of an underlying celiac disease in normal practice for a better approach to the patient. It is necessary to carry out controlled studies on a large number of patients to evaluate the association between these two diseases and the benefits of a gluten-free diet, even when the intestinal symptomatology is not evident.

Nail improvement during alitretinoin treatment: three case reports and review of the literature.

Alitretinoin is an endogenous vitamin A derivative, 9-cis-retinoic acid. Its anti-inflammatory and immunomodulatory efficacy results from controlling leukocyte activity and cytokine production in keratinocytes. We describe three patients with severe chronic hand eczema accompanied by nail dystrophy, which was treated with alitretinoin 30 mg. Clinical evaluation at 6 months showed complete or almost complete clearing of the nail lesions. We also briefly review the literature reporting on nail dystrophy and alitretinoin treatment. There is some evidence of the clinical effect of retinoids on nail formation, owing to the presence of retinoid receptors on the nail matrix. Further studies are required to better understand the impact of alitretinoin in nail diseases. Our observation supports alitretinoin as a treatment option in retinoid-responsive dermatoses associated with nail involvement.

Clinical evaluation and assessment of the therapeutic efficacy of alitretinoin in a group of patients with chronic hand eczema refractory to topical steroid therapy.

AIM: We examined and evaluated the clinical characteristics of patients who had come to the Allergological and Occupational Dermatology unit in Florence with severe CHE refractory to potent topical corticosteroids. We evaluated the efficacy and safety of alitretinoin and we analyzed the response in the three months of follow-up in the group of patients who completed the cycle of therapy. Improvement in clinical signs and symptoms was assessed using mTLSS and PGA. METHODS: All patients were treated daily with single 30-mg doses of oral alitretinoin for 3 to 5 months. The study examined 15 patients with a clinical diagnosis of severe CHE. We found the treatment to be efficient in nine of 13 patients (69%) who were assessed as having "clear" or "almost clear" hands according to PGA. RESULTS AND CONCLUSION: Even if the number of patients we analyzed was limited and lacked a control group the study allowed us to confirm the efficacy of alitretinoin used in a "real life" clinical experience. In addition, thanks to the adoption of proper emollient therapy and avoidance of any relevant allergens or irritants, no recurrence of the condition was observed among the patients who completed therapy with a PGA value of "mild", "almost clear", or "clear" during three months after treatment.
