Objective:To investigate the clinical significance of anti-SSA positive with or without anti-SSB positive in children with lupus nephritis. Methods:The clinicopathological data of children with lupus nephritis newly diagnosed in the Nephrology Department of Nanjing Children’s Hospital from January 1,2018 to January 1,2023 were retrospectively analyzed. Eighty-five children with lupus nephritis were enrolled in this study,including 34 children in the anti-SSA positive with or without anti-SSB positive group(Group A) and 51 children in the anti-SSA and anti-SSB negative group(Group B). Group A was divided into Group A1(anti-SSA positive,22 children)and Group A2(anti - SSA and anti - SSB positive,12 children). The clinical manifestations,SLEDAI - 2K scores and pathological features were compared among all groups,and the remission of lupus nephritis after six months of treatment was followed up. Results:The Group A and Group A1 had no statistical significance compared with the Group B,respectively(P > 0.05). The incidence of rash in the Group A2 was lower than that in the Group B,the difference was statistically significant(P < 0.05),and the non - remission rate in the Group A2 was higher than that in the Group B,the difference was statistically significant(P < 0.05). Conclusion:Children with anti-SSB positive lupus nephritis are all accompanied by anti-SSA positive,and children with both anti-SSA and anti -SSB positive lupus nephritis have a lower incidence of rash clinically,but a higher renal unremission rate for half a year, which may require more aggressive renal treatment.
