Combined use of total glucosides of paeony and hydroxychloroquine in primary Sjögren's syndrome: A systematic review

Abstract

Objective: To assess the effectiveness and safety of the total glucosides of paeony (TGP) combined with hydroxychloroquine (HCQ) on the treatment of primary Sjögren's syndrome (pSS) by conducting a meta-analysis. Methods: Eight databases were searched for randomized controlled trials (RCTs) reporting the use of TGP combined with HCQ for pSS, which are before May 10, 2022. Meta-analyses were performed on disappeared clinical symptoms (dry mouth and dry eyes), Schirmer's test, saliva flow test, erythrocyte sedimentation rate (ESR), index of immunoglobulin G (IgG), immunoglobulin M (IgM), immunoglobulin A (IgA), and adverse events (AEs). The Revman 5.4 software was used for this meta-analysis. Results: Seven RCTs which included 632 participants were identified.
