Background: Bullous pemphigoid (BP) is a widely recognized autoimmune blistering disease (AIBD) linked with a high incidence of morbidity and mortality. The aim of this study was to evaluate the available findings of randomized clinical trial studies to update interventions for Bullous pemphigoid. Methods: This article provides an updated overview of interventions for BP. A literature search was performed using Cochrane Central Register of Clinical Trials, MEDLINE, Scopus, and Web of Science from August 2010 to December 2020. All randomized clinical trials (RCTs) were done on adults and investigated the effectiveness of administered topical or systemic medications versus placebos or controls included in the current systematic review. Three RCTs comprising 363 patients were included in the systematic review. One of the eligible studies was placebo-controlled. All of the included studies used various interventions including, methylprednisolone plus azathioprine versus methylprednisolone plus dapsone, doxycycline versus prednisolone, and intravenous immunoglobulin (IVIG). Results: Following their potentials in disease control, no difference was observed between dapsone and azathioprine; although, dapsone had a higher corticosteroid-sparing potential. The evaluation of the effect of doxycycline in short-term blister control in comparison to corticosteroids showed that the medication was not inferior to prednisolone, although it had a higher long-term safety. Conclusion: Therapeutic outcome of IVIG for steroid-resistant patients was satisfactory. Moreover, the effectiveness and reliability of various immunosuppressive drugs and tetracyclines are investigated by blinded RCTs for the treatment of BP.
