Comparing Clinical Outcomes of Steroid-Sparing Therapy With Rituximab Versus Rituximab Alone in Pemphigus
Background:
Previous clinical trials have demonstrated that rituximab therapy combined with conventional steroid-sparing therapy (SST) has increased rates of disease control for mucous membrane pemphigoid compared with rituximab alone. However, limited data is available regarding the role of SST with rituximab therapy in pemphigus.
Objective:
This study aimed to examine clinical outcomes in pemphigus patients treated with rituximab with SST versus without the addition of SST.
Methods:
A retrospective chart review was performed for adult pemphigus patients in the Southeastern US at Emory between January 1, 2011, and December 31, 2021. Primary outcomes, including time to remission, time to prednisone dose of 10 mg or less, time to cessation of prednisone therapy, and time to relapse after a rituximab cycle, were compared between patients on SST and patients without SST. Results: Following rituximab therapy, there was no difference in time to remission, time to prednisone dose of 10 mg or less, time to cessation of prednisone therapy, or time to relapse for patients with or without SST.
Limitations:
Our study is limited by its retrospective decline, setting at a single academic center, and inclusion of a high proportion of patients with moderate disease.
Conclusions:
The use of SST with rituximab dosing did not improve clinical outcomes related to time to remission, reduction in prednisone dosing, or relapse. These data provide further evidence for the use of rituximab in the majority of pemphigus patients without the need for SST. J Drugs Dermatol. 2024;23(3):e97-e99 doi:10.36849/JDD.7949e.
