Abstract
Background and objective
Association of interleukin-10 (IL-10) polymorphism with diabetes and its complication was recently established, while there were few kinds of research considering the potential role of IL-10 in gestational diabetes (GDM). This study aimed to systematically review the association between serum IL-10 level and GDM susceptibility.
Methods
A comprehensive literature search for the published studies in PubMed, Scopus, CENTRAL (Cochrane Central Register of Controlled Trials), and Google Scholar databases was performed for English language papers published up to 31st July 2020. Following key terms were used: “Cytokine level” OR “Interleukin-10” OR “IL-10,” OR “Pro-inflammatory Cytokines” OR “gestational diabetes mellitus” OR “GDM.” Fixed or random-effects models were used to estimate the pooled SDM and 95% confidence intervals (CIs). Begg’s funnel plot was used to assess the potential for publication bias.
Results
In our meta-analysis, a total of ten studies for the risk of GDM involving 609 GDM cases and 664 controls were included. No significant association between IL-10 levels and risk of GDM as compared to control subjects (SMD = −0.09, 95% CI = −0.73 to 0.55). Subgroup analysis based on ethnicity also does not reveal any association between IL-10 levels and risk of GDM as compared to control subjects has more or less similar trends in Caucasian (SMD = −0.07, 95% CI = −0.58 to 0.45) as well as Asian population (SMD = −0.03, 95% CI = −1.56 to 1.49).
Conclusion
Our findings suggest that the serum IL-10 level may not be significantly associated with an increased risk of susceptibility to GDM. Further well-designed prospective studies embedded with a large sample size are needed to confirm these findings.
