Guselkumab Treatment Outcomes and Persistence in a Nationwide Real-world Cohort of Patients with Plaque Psoriasis.

Guselkumab treatment outcomes and persistence were assessed in a real-world cohort of Finnish patients with difficult-to-treat plaque psoriasis over a median follow-up of 1 year. Data on 181 patients who initiated guselkumab at the 15 study centres were collected retrospectively from the patient charts. Prior exposure to biologic therapies was common, with 56% and 35% having used at least 1 and 2 biologics, respectively. Median guselkumab treatment duration was 11 months with 21 patients (12%) discontinuing treatment during follow-up. Of 85 patients with a follow-up duration of at least 1 year, 73 (86%) were still on guselkumab at 1 year. Significant improvements during follow-up were seen in the absolute Psoriasis Area and Severity Index (PASI) scores with 32 patients (80%) having absolute PASI ≤ 2 after a 9-14-month treatment. Guselkumab treatment was effective and treatment persistence was high in the nationwide Finnish real-life setting.

Cyclosporine treatment in severe gestational pemphigoid.

Gestational pemphigoid, a rare autoimmune skin disease typically occurring during pregnancy, is caused by autoantibodies against collagen XVII. Clinically it is characterised by severe itching followed by erythematous and bullous lesions of the skin. Topical or oral glucocorticoids usually relieve symptoms, but in more severe cases systemic immunosuppressive treatments are needed. Data on immunosuppressive medication controlling gestational pemphigoid are sparse. We report 3 intractable cases of gestational pemphigoid treated with cyclosporine.
