Abstract
So far, there was no report on the prevalence and clinical relevance of anti-Ro52 in primary Sjögren's syndrome (pSS) patients in Korea. In this study, we investigated the prevalence and the clinical relevance of anti-Ro52 in Korean patients with pSS. We retrospectively reviewed the medical records of 96 patients with pSS. On the first visit clinical manifestations, laboratory features and autoantibodies were assessed. We divided subjects into 4 groups according to the presence of anti-Ro60 or anti-Ro52 and investigated the association between those autoantibodies and clinical manifestations. Anti-Ro52 (66.7%) was the most frequently detected autoantibody, followed by anti-Ro60 (52.1%) and anti-La (49.0%). Patients with anti-Ro52 had higher frequency of liver and muscle involvements than those without, while anti-Ro60 exhibited negative association with liver involvement. Anti-Ro52 showed significant relative risk for liver involvement (OR = 5.987, P = 0.038, 95% CI = 1.109-32.326), while anti-Ro60 showed inverse relative risk for liver involvement (OR = 0.122, P = 0.003, 95% CI = 0.031-0.479). Anti-Ro52 also showed significant OR for muscle involvement (OR = 9.533, P = 0.044, 95% CI = 1.059-85.793). In conclusion, anti-Ro52 was the most frequently detected autoantibody except ANA in patients with pSS in Korea. Anti-Ro52 was significantly associated with liver and muscle involvements, while anti-Ro60 was inversely associated with liver involvement in Korean patients with pSS.
