Background: Popular treatment modalities for pemphigus vulgaris are dexamethasone cyclophosphamide pulse (DCP) therapy and rituximab. However, no previous studies are available which have compared the efficacy of the two modalities. Aim: This study aims to study the response of pemphigus vulgaris to DCP and rituximab therapy and to compare the efficacy and safety of the two modalities over a period of 1½ years. Materials and Methods: This was an observational retrospective study. The medical records of a total of 14 pemphigus vulgaris patients from July 2016 to July 2018 were retrieved for analysis who were treated with either DCP therapy or rituximab (7 in each group). Patients treated with any other modality except DCP/rituximab were excluded from the study. The pemphigus disease area index (PDAI) scores at baseline, 1 month, 6 months, 12 months, and 18 months were analyzed using statistical software (Stata Corp. 2013. Stata Statistical Software: Release 13. College Station, TX, Stata Corp. LP, Texas, USA). Outcome Measures: Time to achieve the end of consolidation phase, improvement in PDAI scores, adverse effects, and relapse. Results: Rituximab group achieved early remission; however, there was no statistically significant difference in the two groups in the time when they reached the end of consolidation phase. Repeated measure anova showed significant difference in PDAI scores within the two groups over time. One patient in DCP group relapsed following discontinuation of cyclophosphamide due to complications. Overall, the scoring of disease severity was markedly reduced in both the groups. Conclusion: Both DCP therapy and rituximab were found to be extremely and equally effective in inducing and maintaining remission.
