Abstract:

Objective

To evaluate the association between microRNA gene polymorphisms and rheumatoid arthritis (RA) using Meta-analysis.

Methods

A systematic search of Chinese biomedical literature database, VIP database, Wanfang data, CNKI, PubMed, Cochrane, and Embase database was performed to identify articles reporting on the association between microRNA gene polymorphisms and RA. The search time limit was from the inception of the database to May 1, 2020. The references of retrieved articles were manually searched to ensure the comprehensiveness of the retrieval. Studies meeting the inclusion criteria were included to conduct data extraction and quality evaluation. Two researchers independently screened the literature, extracted the data, and evaluated the risk of bias in the included studies. A Meta-analysis was performed using Stata 15.1 software.

Results

A total of 14 cohort studies were included, involving 1945 RA cases and 2405 controls. Meta-analysis results showed that the expression level of G/G genotype of miR-146a in RA patients was significantly higher than that in normal controls [OR=1.15, 95%CI (1.00, 1.33), P=0.048], other phenotypes were not significantly associated with the risk of RA [C/C: OR=0.94, 95%CI (0.83, 1.07), P=0.353; G/C: OR=0.92, 95%CI(0.82,1.03), P=0.135]. The C/T genotype of miR-499 in RA patients was significantly lower than that in normal controls [OR=0.84, 95%CI (0.72,1.00), P=0.044], there were no significant differences in other genotypes [T/T: OR=0.97, 95%CI (0.77,1.24), P=0.831; C/C: OR=1.40, 95%CI (0.96,2.05), P=0.713]. Analysis of subgroups by race showed that there was no statistically significant association between the polymorphisms of miR-146a and miR-499 and the incidence of RA in Caucasian and Asian populations (P>0.05).

Conclusion

This study find that the G/G genotype of miR-146a and C/T genotype of miR-499 are related to genetic susceptibility to RA.
