Introduction: Several published results have established variations in respect to plasma/serum macrophage migration inhibitory factor (MIF) levels and gene polymorphisms with systemic lupus erythematosus (SLE). This study gave a more concise estimation on the MIF levels for SLE patients and established the association between MIF polymorphisms and SLE.Material and Methods: All articles were searched from PubMed, Embase, Web of Science, Wan-Fang, Chinese Biological Medical Literature, and China National Knowledge Infrastructure up to 6th October 2017, with no language restriction. Pooled standard mean difference with 95% confidence interval was evaluated using random effect model. Thirteen articles were used for this meta-analysis, with 620 SLE patients and 779 healthy controls assessed for MIF levels, and 2,159 SLE patients and 2,574 healthy controls considered for MIF-173 C/G and MIF-794 CATT polymorphisms.Results: There was a significant higher MIF levels in SLE patients than in healthy controls (p = 0.004). The subgroup analysis showed Asians and ages < 30 had higher MIF levels in SLE patients than in healthy controls. It was evident that patients with systemic lupus erythematosus diseases activity index scores < 8 and ≥ 8, and disease duration for both year < 5 and ≥ 5 of SLE had higher MIF levels when compared to healthy controls. We found a significant association between SLE and MIF-173 C/G, but not MIF-794 CATT.Conclusions: This study provided evidence of significant higher MIF levels in SLE patients and supported the association of MIF-173 C/G and SLE. However, we were not able to establish an association between MIF-794 CATT and SLE. [ABSTRACT FROM AUTHOR]

Aim: To derive a more precise estimation of carotid intima-media thickness (CIMT) levels in patients with type 1 diabetes mellitus (T1DM) by meta-analysis. Methods: PubMed and Embase databases were searched to identify all available studies comparing CIMT levels between T1DM group and control group. Meta-analysis was performed to compare the difference of overall mean CIMT levels between the two groups. Publication bias was evaluated by funnel plot, Begg' test and Egger' test. Meta-regression analysis was conducted to investigate the influential factors on CIMT difference. The meta-analysis was conducted by STATA 12.0 software. Results: A total of 1840 articles were obtained after searching databases; 47 studies were finally included in the meta-analysis. Significant heterogeneity was observed among these studies (Q = 768.75, < 0.001, I² = 94.0%). Compared with the control group, the T1DM group had significantly higher CIMT levels (standardized mean difference: 1.01, 95% CI: 0.75-1.28; < 0.001). A likely source of heterogeneity was Newcastle-Ottawa Scale (NOS) scores and sample size ratio of patents and controls. The funnel plot did not show a skewed or asymmetrical shape, and the result of Begg' test and Egger' test was P = 0.178 and P = 0.145 respectively. Accordingly, it could be assumed that publication bias was not present. Conclusion: T1DM patients have significantly increased CIMT levels compared to control subjects. [ABSTRACT FROM AUTHOR]
