Abstract
- Abstract Background Rituximab (RTX) has been utilised off‐label for a variety of dermatological indications beyond pemphigus vulgaris. Efficacy has been reported in other immunobullous disorders, inflammatory dermatoses and connective tissue diseases. Objectives To assess the off‐label use of RTX in our centre with respect to indications, frequency and duration of treatment, efficacy, and adverse events. Methods Charts were retrospectively reviewed for all patients who received dermatologist‐prescribed RTX infusions off‐label at our centre between 2009 and 2022. Efficacy was categorised based on reported percentage reduction of disease activity: very good (75%–100%), good (50%–74%), partial (25%–49%) and none (0%–24%). Results Twenty‐nine patients received RTX off‐label during this time period. Infusions were discontinued in 28% (n = 8), due to insufficient clinical response. Median treatment duration for those on 6‐12‐monthly regular infusions was 2.4 years (range 0.5–11 years). Indications included cutaneous lupus (n = 9), mucous membrane pemphigoid (n = 5), pyoderma gangrenosum (n = 6), lichen planus (n = 2), dermatomyositis (n = 1), livedoid vasculitis (n = 1), sarcoidosis (n = 1), bullous pemphigoid (n = 1), pemphigus vulgaris, foliaceus and vegetans (n = 1 each). Clinical improvement was documented in 79% (n = 23); very good in 48% (n = 14), good in 17% (n = 5), and moderate in 14% (n = 4). Clinical efficacy in immunobullous disorders was 100% (9/9), 67% in cutaneous lupus (6/9), 33% in pyoderma gangrenosum (2/6), and 50% in lichen planus (1/2). No side effects were documented for 79% (n = 23). Adverse peri‐infusion events were seen in three patients (10%). Four patients died during follow up; one due to neutropenic sepsis with a background of advanced malignancy, and three due to Covid‐19. Conclusions RTX was prescribed for multiple off‐label dermatological indications, often for recalcitrant disease. Responses were good overall, with a reassuring safety profile. Three patients died of Covid‐19; knowledge of the impact of RTX on the immune response and efficacy of vaccines is expanding and will continue to inform guidelines for RTX use in the post‐Covid era.
