Résumé

This study aimed to investigate the predictive factors for uveitis recurrence (UR) risk in Behcet's disease (BD) patients. BD patients (n=164) with a history of uveitis were recruited, and demographic data, clinical features, and laboratory tests were recorded. Uveitis was defined as anterior uveitis, intermediate uveitis, posterior uveitis, panuveitis referring to the "International Uveitis Study Group recommendations for the evaluation of intraocular inflammatory disease". In total, there were 70 UR patients and 94 non-UR patients. Compared to non-UR patients, UR patients appeared to be older and presented with increased uveitis occurrence rate and times within 3 months, oral ulcers occurrence rate, as well as higher concentrations of triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL), and serum amyloid A (SAA). Multivariate logistic model disclosed that uveitis occurrence times within 3 months, oral ulcers, TG, LDL, and SAA independently predicted higher risk of UR. Furthermore, receiver operating characteristic curve analysis showed that the combination of uveitis occurrence times within 3 months, oral ulcers, TG, LDL, and SAA exhibited a high predictive value for UR risk with an area under the curve of 0.983 (95%CI: 0.969−0.998). In conclusion, uveitis occurrence times within 3 months, oral ulcers, TG, LDL, and SAA might be potential predictive factors for UR risk in BD patients, which can help in prevention and management of the disease.

Résumé

OBJECTIVE@#Behcet's disease (BD) is an autoimmune disorder that causes most commonly mouth and genital ulcerations and erythema nodules of the skin and currently has limited options of therapeutic medicines. Metformin is recently reported to suppress immune reaction, and we hypothesized that metformin could be an option for treatment of BD.@*METHODS@#Thirty patients with BD were enrolled in this perspective single-blinded, before-after study. We recorded the changes in the mucocutaneous activity index for BD (MAIBD), relapse frequency, C-reactive protein (CRP) level and erythrocyte sedimentation rate (ESR) after metformin treatment to assess the changes in the disease activity. We also analyzed the changes in the protein and mRNA expression levels of Foxp3, interleukin-35 (IL-35), transforming growth factor-β (TGF-β), Ror-γt, IL-17, and tumor necrosis factor- (TNF-) in these patients using ELISA and qRT-PCR.@*RESULTS@#Of the 30 patients enrolled, 26 completed the trial. After the treatment, favorable responses were achieved in 88.46% (23/26) of the patients, and partial remission was obtained in 11.54% (4/26) of them. During the treatment, 8 patients complained of gastrointestinal side effects, for which 4 chose to withdraw from the study in the first week. Our results showed that metformin treatment decreased MAIBD and relapse frequency in the patients, and significantly lowered the clinical inflammatory indexes including CRP and ESR. The results of ELISA and qRT-PCR revealed that metformin treatment obviously increased Foxp3 and TGF-β expressions at both the protein and mRNA levels and significantly decreased the levels of ROR-γt, IL-17 and TNF- as well as IL-35 level in these patients.@*CONCLUSIONS@#Metformin treatment relieves the clinical symptoms, reduces the inflammatory reaction indexes and regulates the Treg/Th17 axis in patients with BD, suggesting the potential of metformin as a candidate medicine for treatment of BD.
