Interleukin-10-1082A/G polymorphism and diabetic nephropathy: a meta-analysis

Area of Science:

• Genetics and Immunology
• Nephrology
• Metabolic Diseases

Background:

• Diabetic nephropathy (DN) is a major complication of diabetes.
• Previous studies on the association between Interleukin-10 (IL-10) -1082A/G polymorphism and DN risk yielded inconclusive results.
• A comprehensive meta-analysis is needed to clarify this relationship.

Purpose of the Study:

• To investigate the association between the IL10-1082A/G polymorphism and the risk of developing diabetic nephropathy.
• To synthesize evidence from existing case-control studies through a meta-analysis.

Main Methods:

• A systematic literature search was conducted using PubMed and EMBASE databases.
• Data from relevant case-control studies were independently extracted by two authors.
• Statistical analysis involved calculating Odds Ratios (ORs) with 95% Confidence Intervals (CIs) to assess the risk association.

Main Results:

• Nine case-control studies comprising 4165 subjects were included in this meta-analysis.
• The IL10-1082A/G polymorphism was significantly associated with an increased risk of DN (OR=1.21; 95% CI 1.07-1.37; P=0.002).
• Subgroup analyses by race (Caucasians and Asians) and sample size consistently showed an increased DN risk associated with the polymorphism.

Conclusions:

• This meta-analysis provides strong evidence that the IL10-1082A/G polymorphism contributes to the susceptibility of developing diabetic nephropathy.
• The findings highlight the potential role of IL-10 genetic variations in DN pathogenesis.
