Abstract:Objective To study the clinical characteristics and risk factors of adult systemic lupus erythematosus with digestive system manifestations, to establish a risk assessment model, and to provide reference for diagnosis and prevention for the disease. Methods We retrospectively collected 307 patients of SLE diagnosed in the First and Second Affiliated Hospital of Guangxi Medical University from August 2012 to August 2017, and systematically analyzed clinical datas, especially focus on the patients with digestive system manifestations. Results There were 61 patients (19.9%) with digestive system manifestations appearing abdominal pain, nausea, vomiting and diarrhea. The incidence of blood system damage, polyserositis and pyeloureterectasis in SLE patients with digestive system manifestations were higher than those without digestive system manifestations, the difference was statistically significant (P?0.05). Decreased ALB, C3, PLT and increased CRP, ALT, AST, ALP, GGT were also associated with digestive system manifestations of SLE patients, the difference was statistically significant (P?< 0.05). Multivariate logistic regression analysis showed that blood system damage, polyserositis, decreased ALB and elevated ALT were independent risk factors of digestive system manifestations. Conclusions Digestive system symptom is a common clinical manifestation of SLE. The patients of SLE with digestive system symptom have long hospital stay, various clinical and imaging manifestations. As independent risk factors, blood system damage, polyserositis, decrease of Alb and elevation of ALT can be used to establish a risk assessment model for SLE complicated with digestive system symptoms.
