PurposeThe purpose of this article was to systematically review the literature to identify the impact of primary Sjögren's syndrome (pSS) on specific health-related quality of life (HRQoL) domains.MethodsA meta-analysis was performed, and the related articles were searched in Medline, Embase, Cochrane Library, China National Knowledge Infrastructure, China Biology Medicine, and Web of Science databases and in reference lists of articles and systematic reviews. Score of the Short Form 36 (SF-36) questionnaire was used as the outcome measurement, and mean differences (MD) with 95% confidence intervals (CIs) were calculated.ResultsSeven studies were included, comprising 521 patients with pSS and 9,916 healthy controls. The SF-36 questionnaire score of each domain (physical function, role physical [RP] function, emotional role function, vitality, mental health, social function, body pain, general health, physical component scale, mental component scale) was lower in patients with pSS than in healthy controls, especially the score in the dimension of RP function.ConclusionThis meta-analysis showed that patients had lower pSS score in each dimension of the SF-36, mostly in the RP function. This demonstrated that targeted interventions should be carried out to improve the HRQoL of pSS patients.
