Objective: To review the efficacy and safety of rituximab in vasculitic neuropathy (VN) METHODS: A literature search was performed on Medline and Embase up until 2017. It included terms related to "vasculitis","vasculitic neuropathy" and "Rituximab". Research was carried out by two reviewers. The main outcome was rituximab efficacy.
Results: Of an initial selection of 702 articles, 5 remained with a level of evidence between 1+ and 3 and variable recommendation degree. In the only clinical trial included, rituximab was superior to conventional therapy for cryoglobulinemic vasculitis with VN showing an increase in drug retention rate (64.3% vs. 3.5%; P<.001)and with a lower rate of serious adverse effects (.12 vs. .48). Cohort studies of patients with cryoglobulinemic vasculitis showed improvement and complete/partial remission of VN. In a series of 5 cases of refractory EGPA suffering from VN, 60% and 20% of patients achieved complete and partial remission respectively.
Conclusions: Rituximab seems an effective and safe treatment for VN in the context of cryoglobulinemic vasculitis. Evidence for specific efficacy in VN in the context of other types of vasculitis is lacking.
