52-Week Mid-term Efficacy of Tildrakizumab in Moderate-to-severe Psoriasis: A Real-life Multicenter Experience.

Tildrakizumab is an IL-23-inhibitor that has been approved to treat plaque psoriasis. However, few reports have become available on its efficacy profile in the real-world. Our objective was to study the mid-term efficacy of tildrakizumab in patients with moderate-to-severe psoriasis in the Spanish routine clinical practice setting. This was a retrospective multicenter study that included a total of 91 psoriatic patients on tildrakizumab. The mean Psoriasis Area and Severity Index (PASI) was 9.09 (SD, 5.30). The overall tildrakizumab survival rate was 93.47% for a mean treatment exposure of 30.18 weeks (SD, 16.57). No drug discontinuation was associated with drug tolerability, or adverse reactions. Absolute PASI ≤3 was reached by 91.3% and 96.5% of the patients on weeks 28 and 52, respectively. Response was not impacted by weight, age (>65), metabolic syndrome, presence of arthritis, or previous number of biological therapies used. Based on our own experience tildrakizumab is an effective strategy to treat plaque psoriasis and difficult-to-treat-areas.

Pityriasis Rubra Pilaris: A Multicentric Case Series of 65 Spanish Patients.

INTRODUCTION: PRP is a rare entity of unknown etiopathogenesis. Lack of management guidelines makes it a challenge for clinicians. OBJECTIVE: To add our experience to increase evidence about PRP. METHODS: We performed a retrospective, descriptive and multicentric study of 65 patients with PRP, being the largest European case series of patients with PRP. RESULTS: PRP was more frequent in male patients with an average age of 51 years, but erythrodermic forms presented in older patients (average age 61 years). Six (75%) paediatric patients and ten (60%) non-erythrodermic adults controlled their disease with topical corticosteroids. On the contrary, 26 (68%) erythrodermic patients required biologic therapy as last and effective therapy line requiring an average of 6.5 months to achieve complete response. CONCLUSION: Our study showed a statistical difference in terms of outcome and response to treatment between children or patients with limited disease and patients who develop erythroderma.

Series of Fourteen Cases of Topical Imiquimod 5% in Lentigo Maligna: Treatment Modalities and Clues for Detecting Recurrences.

Topical imiquimod has been used off-label as monotherapy or adjuvant treatment for lentigo maligna. Our aim is to describe treatment modalities, clinical outcomes, and management of recurrence in patients receiving imiquimod for lentigo maligna. Patients from our unit with lentigo maligna or lentigo maligna melanoma treated with imiquimod 5% as monotherapy or in combination with surgery were included in this study. Fourteen cases were recruited (85.7% lentigo maligna and 14.3% lentigo maligna melanoma). Eight patients (57.1%) received imiquimod without surgery, and six (42.9%) underwent narrow excision before beginning treatment. During the follow-up period, pigmentation reappeared in 6 patients (4 postinflammatory hyperpigmentation and 2 relapses). Relapses were managed with very narrow excision (1mm margin) and retreatment with imiquimod 5%. All imiquimod modalities showed well-tolerated side effects and low recurrence rates, with long periods of follow-up. Imiquimod appears to be a versatile option for treating LM in suitable candidates.
