About

Based on clinical manifestations, laboratory data and intestinal microflora detection, the cognitive function characteristics of patients with systemic lupus erythematosus and cerebrovascular disease and its relationship with intestinal microflora were analyzed to explore the possible pathogenesis of lupus cerebrovascular disease.

Full description

This study was a retrospective and prospective cohort study. They were divided into three groups, namely SLE group, SLE cerebrovascular disease group and healthy control group. Each group included 60 patients [Anticipated].

1. Retrospective study: The SLE patients admitted to Nanfang Hospital from 2018 to 2022 were retrieved. The patients enrolled from September 2018 to September 2021 applied for exemption from informed consent, and the patients enrolled from September 2021 to September 2022 voluntarily signed informed consent. Patients were selected according to inclusion and exclusion criteria, and clinical and laboratory data of all subjects were recorded.
2. Prospective study: Obtain the consent of the subjects, sign the informed consent, and record the clinical and laboratory examination data of all the subjects.

(1) Cognitive function assessment; (2) Fresh stool and serum were collected, and 16s rRNA technology was used for intestinal flora detection, and QIIME2 platform was used for flora analysis; Serum inflammatory factors were detected and metabolomic analysis was performed.

The clinical data of all enrolled patients were statistically analyzed.

Enrollment: 180 estimated patients

Sex: All

Ages: 14 to 55 years old

Volunteers: Accepts Healthy Volunteers
