Rituximab provides long-term benefit in systemic sclerosis
Treatment with rituximab was associated with significantly improved skin and lung fibrosis in systemic sclerosis over approximately 2 years, according to a study.
In this single-center cohort study, data from 29 patients with SSc enrolled in the DESIRES trial who opted to continue to receive rituximab were analyzed after a median follow-up of 96 weeks.
After 1 course of rituximab significant improvement in modified Rodnan skin score (MRSS) were noted and after 3 courses, significant improvement in the percentage of predicted forced vital capacity (FVC%) were observed. These improvements were sustained during follow-up.
The 16 patients who had MRSS improvement of ≥9 had a greater decrease in serum levels of IgG and IgA compared with the 13 patients who had MRSS improvement of≤8.
The authors note that a “decrease in serum IgA levels significantly correlated with the improvement in MRSS.”
