RESUMO

OBJECTIVE: Mucous membrane pemphigoid (MMP) is an autoimmune blistering disorder with tendency to scarring. Long term immunosuppressive treatment may be required to minimize the consequences of the disease. METHODS: In this retrospective study, we investigated the efficacy of rituximab (RTX) in MMP patients and compare the beneficial effects of early versus late administration of RTX. Medical records of 24 MMP patients who were treated with 500 mg RTX on day 1, then weekly for 4 consecutive weeks were reviewed. RESULTS: Twenty-one patients (87.5%) reached disease control (DC) at the mean interval of 4.95 months (SD: 5.15; range: 1-24) after RTX. Complete remission (CR) with scarring was achieved in 45.8% (n = 11) and 33.3% (n = 8) attained CR without any residual scar (total CR with or without scar 79.1%). Two patients (8.3%) reached partial remission including persistent gingivitis. Only one patient progressed from non-cicatricial to cicatricial MMP despite receiving RTX. 47.6% (n = 10) of patients experienced relapse after achieving DC at a mean interval of 15.2 months (range: 6-30, SD: 7.0). Considerably, earlier the RTX was administered, sooner the DC was obtained (Pearson r = 0.742, p-value < .001). CONCLUSIONS: These results suggest that RTX may prevent further scarring and progression in MMP patients especially if administered early.
