Objective. Type 2 deiodinase (Dio2) is an enzyme responsible for the conversion of T4 to T3. The Thr92Ala polymorphism has been shown related to an increased risk for developing type 2 diabetes mellitus (T2DM). The aim of this study is to assess the association between this polymorphism and glycemic control in T2DM patients as marked by the HbA1C levels.Design and Methods.The terms “rs225014,” “thr92ala,” “T92A,” or “dio2 a/g” were used to search for eligible studies in the PubMed, Embase, and Cochrane databases and Google Scholar. A systematic review and meta-analysis of studies including both polymorphism testing and glycated hemoglobin (HbA1C) assays were performed.Results. Four studies were selected, totaling 2190 subjects. The pooled mean difference of the studies was 0.48% (95% CI, 0.18–0.77%), indicating that type 2 diabetics homozygous for the Dio2 Thr92Ala polymorphism had higher HbA1C levels.Conclusions. Homozygosity for the Dio2 Thr92Ala polymorphism is associated with higher HbA1C levels in T2DM patients. To confirm this conclusion, more studies of larger populations are needed.

Background: Although previous studies suggested the protective effect of zinc for type-2 diabetes, the unitary causal effect remains inconclusive. Objective: We investigated the causal effect of zinc as a single intervention on glycemic control in type-2 diabetes patients, using a systematic review of RCTs and two-sample Mendelian randomization (MR). Methods: Four outcomes were identified: fasting blood glucose/fasting glucose, hemoglobin A1c (HbA1c), homeostasis model assessment of insulin resistance (HOMA-IR), and serum insulin/fasting insulin level. In the systematic review, four databases were searched up to June 2021. Results were synthesized through the random-effects meta-analysis. Single nucleotide polymorphisms (SNPs) that are independent and are strongly related to zinc supplements were selected from MR-base to perform the two-sample MR with inverse-variance weighted (IVW) coefficient. Results: In the systematic review, 14 trials were included. The zinc supplement led to a significant reduction in the post-trial mean of fasting blood glucose (mean difference (MD): -26.52, 95%CI: -35.13, -17.91), HbA1C (MD: -0.52, 95%CI: -0.90, -0.13), and HOMA-IR (MD: -1.65, 95%CI: -2.62, -0.68), compared to the control group. In the two-sample MR, zinc supplement with 2 SNPs associated with lower fasting glucose (IVW coefficient: -2.04, 95%CI: -3.26, -0.83), but not specified type-2 diabetes. Conclusion: Although the study was limited by the few trials (review) and SNPs (two-sample MR), we demonstrated that the single zinc supplementary improved glycemic control among type-2 diabetes patients with causal evidence to a certain extent.
