Evaluation of clinical factors and outcome of systemic glucocorticoid therapy discontinuation in patients with pemphigus achieving complete remission.

Abstract

Therapy discontinuation of systemic glucocorticoid treatment for pemphigus remains uncertain at the clinical end point of complete remission. The objective of this study was to identify the factors associated with achieving complete remission off therapy (CROT) and analyze the occurrence of relapse after therapy discontinuation. A retrospective cohort study was conducted at the Department of Dermatology of Peking University First Hospital. A total of 447 patients with pemphigus treated from 2005 to 2020 were identified. Univariate and multivariate analyses were conducted to analyze the associated factors of CROT and to evaluate the outcomes. The mean age was 48 years (±13.4 years), and 54.6% of the patients were women. During a median follow-up of 59 months (43-87.5 months), 160 of 447 (35.8%) patients achieved CROT after a median treatment duration of 51 months (38-66.2 months). Patients with a shorter therapy duration to complete remission on minimal therapy and negative desmoglein antibodies tested in remission were more likely to achieve early CROT. Thirty-five of 160 (21.9%) patients experienced relapse after CROT. Patients who discontinued therapy without guidance experienced significantly faster and higher occurrences of relapse than those withdrawing under guidance (log-rank p = 0.01). Minimal therapy maintenance ≤8 months from complete remission on minimal therapy and positive desmoglein antibodies tested at withdrawal increased the risk of early relapse after CROT.
