Levels of the macrophage migration inhibitory factor and polymorphisms in systemic lupus erythematosus: a meta-analysis

Abstract

IntroductionSeveral 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 methodsAll 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.ResultsThere 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.ConclusionsThis 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.

New Insights into the Role and Mechanism of Macrophage Migration Inhibitory Factor in Epinephelus awoara Infected with Vibrio alginolyticus

“…MIF increased tumour cell proliferation by releasing cytokines including TNF-α, IL-1b and IL-6 (Kolostova et al, 2022). In our study, tissue levels of MIF, TNF-α and IL-1 were up-regulated in infected E. awoara; these results were similar to previously reported results (Sam et al, 2021).These results may offer a novel therapeutic strategy for treating bacterial disease.…”

Increasing Levels of Macrophage Migration Inhibitory Factor in COVID-19 Infection and Its Pathophysiological Role; Cut-off Value Determination Might Be Clinically Misleading

“…In fact, a wide range of variations has been observed in healthy control groups in different studies. In one meta-analysis study (37), the healthy controls serum levels ranged from 0.3 ± 0.012 up to 61 ± 58.7 ng/mL (38) based on the studies included in the meta-analysis. Also, in another meta-analysis (27), the mean serum levels of the control groups among different studies ranged from 0.121 ± 0.001 up to 46.829 ± 38.394 ng/mL (39).…”

Case report of systemic lupus erythematosus in a middle-aged male with facial palsy at onset

“…Sex differences indicate that the onset of LN may be correlated with oestrogen levels. However, several studies have reported regional and ethnic differences in terms of age at peak onset in men with LN [7][8][9][10]. Type IV LN is the most common pathological type in both male and female patients.…”
