Abstract
The purpose of this meta-analysis was to investigate whether serum resistin level was associated with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) by comparing serum resistin levels between RA or SLE patients and normal controls. PubMed and EMBASE databases (up to May 13, 2014) were used to search all related articles. The weighted mean differences (WMDs) with 95 % confidence interval (CI) were calculated using random-effect model analysis. The Cochrane Q test and I 2 statistic were used to test heterogeneity. To assess publication bias, the Egger’s test and visual observation of a funnel plot were used. The Newcastle-Ottawa scale was used to assess the study quality. The STATA statistical software (version 11.0) was applied to deal with statistical data. A total of eight studies of RA including 620 patients and 460 healthy controls, and six studies of SLE including 559 patients and 430 healthy controls were finally included in the meta-analysis. The results revealed that the serum resistin levels in RA were significantly higher than those in normal controls (WMD = 0.767 ng/ml, 95 % CI = 0.114–1.419, P = 0.021), but there was no significant difference between SLE patients and normal controls (WMD = 2.771 ng/ml, 95 % CI = −0.521–6.063, P = 0.099). Publication bias was undetected. In conclusion, this meta-analysis indicate that serum resistin level was significantly elevated in RA patients.
