Guillain-Barré syndrome (GBS), an acquired immune-mediated autoimmune disorder affecting the peripheral nervous system (PNS), is associated with autoimmunity. The presence of autoantibodies in the blood is an important feature of autoimmune diseases. Herein, we explored the distribution characteristics of the antinuclear antibodies (ANAs) in GBS and the correlation between ANAs and disease severity. We retrospectively analyzed the clinical data of 170 GBS patients. According to ANAs, GBS patients were divided into ANAs positive and negative groups. The clinical characteristics of these two groups were compared. The distribution difference was also compared between male and female GBS patients. In addition, all enrolled patients were divided into more severe group and milder group according to whether the Hughes score at nadir ≥ 3 or not. Gender, age, and ANAs were compared between the two groups. In this study, the positive rate of ANAs was 27.1 % in 170 GBS patients, among which anti-SSA-52/Ro52 antibody and antimitochondrial antibody M2 made up the largest proportion. In the ANAs positive group, GBS patients had longer days of hospitalization, more respiratory function involvement, and higher level of CSF IgG than the ANAs negative group. Compared to the ANAs negative group, Medical Research Council (MRC) scores on admission and at nadir were lower, and Hughes functional Grading Scale (HFGS) scores on admission and at nadir were higher in GBS patients with ANAs positive group. Erasmus GBS Respiratory Insufficiency Score (EGRIS) in ANAs positive GBS patients group was significantly higher than ANAs negative group. Gender had no effects on the distribution of ANAs in GBS patients. Moreover, we found that the anti-SSA-60 antibodies and age were positively correlated with GBS severity. In addition, in the anti-SSA-60 antibody positive group, GBS patients had longer days of hospitalization, more respiratory function involvement, higher HFGS scores on admission/at nadir, and lower MRC scores at nadir compared with the anti-SSA-60 antibody negative group. Anti-SSA-52/Ro52 antibody and antimitochondrial antibody M2 were the most common ANAs in GBS patients. Anti-SSA-60 antibodies and age positively correlated with GBS severity. Positive anti-SSA-60 antibodies and age were independent predictors of GBS patient severity. •In 170 Guillain-Barré syndrome (GBS) patients, antinuclear antibodies (ANAs) positive rate was 27.1%, among which anti-SSA-52/Ro52 antibody and antimitochondrial antibody M2 were the most common.•GBS patients with ANAs positive group had longer days of hospitalization, more respiratory function involvement, higher levels of CSF IgG, lower scores of MRC on admission and at nadir and higher scores of HFGS on admission and at nadir, significantly higher EGRIS compared with ANAs negative group.•The anti-SSA-60 antibodies and age had a correlation with GBS severity.•In anti-SSA-60 antibody positive group, GBS patients had longer days of hospitalization, more respiratory function involvement, higher scores of HFGS on admission/at nadir and lower scores of MRC at nadir.
