Updates on the Management of Autoimmune Bullous Diseases

Autoimmune bullous diseases are associated with high morbidity and mortality. Traditionally, systemic corticosteroids and conventional immunosuppressive agents have been the mainstay of treatment, but their broad immunosuppressive effects and long-term complications have prompted the exploration of newer more targeted therapies. This review explores the evolving landscape of therapeutic options for immunobullous diseases, with a particular focus on pemphigus, bullous pemphigoid (BP), and mucous membrane pemphigoid, by searching PubMed, clinicaltrials.gov, and Cochrane databases for published literature from 2014 to 2023. We discuss emerging treatments for pemphigus such as B cell modulatory drugs, anti-inflammatory drugs, those inhibiting autoantibody half-life or blister-inducing activity, and stem cell therapy, while offering insights into the level of evidence, potential benefits, and limitations of each approach. The role of biologics and novel therapies like rituximab, omalizumab, and dupilumab in reshaping the management of BP is also discussed. The article highlights the need for further research, clinical trials, and comparative studies to determine the most effective and safest treatment options for patients with immunobullous diseases.
