Progress in genetics of type 2 diabetes and diabetic complications.

ABSTRACT: Type 2 diabetes results from a complex interaction between genetic and environmental factors. Precision medicine for type 2 diabetes using genetic data is expected to predict the risk of developing diabetes and complications and to predict the effects of medications and life-style intervention more accurately for individuals. Genome-wide association studies (GWAS) have been conducted in European and Asian populations and new genetic loci have been identified that modulate the risk of developing type 2 diabetes. Novel loci were discovered by GWAS in diabetic complications with increasing sample sizes. Large-scale genome-wide association analysis and polygenic risk scores using biobank information is making it possible to predict the development of type 2 diabetes. In the ADVANCE clinical trial of type 2 diabetes, a multi-polygenic risk score was useful to predict diabetic complications and their response to treatment. Proteomics and metabolomics studies have been conducted and have revealed the associations between type 2 diabetes and inflammatory signals and amino acid synthesis. Using multi-omics analysis, comprehensive molecular mechanisms have been elucidated to guide the development of targeted therapy for type 2 diabetes and diabetic complications.

Project description:Microvascular complications, affecting small blood vessels, can lead to serious conditions such as kidney failure, painful nerve damage, and vision loss. Early detection and effective treatment of these issues are vital for improving patient outcomes and reducing healthcare expenses. Thus, this study aimed to assess diabetic microvascular complications among adults with type 2 diabetes in Adama, central Ethiopia. An institutional-based cross-sectional study was conducted among 381 adult type 2 diabetes patients. A computer-generated simple random sampling method was used to select study participants. Data were collected using a structured data extraction checklist. The collected data were entered into Epi info version 7.2 and exported to SPSS version 27 for processing and analysis. Binary logistic regression was employed to model the association between diabetic microvascular complications and explanatory variables. An adjusted odds ratio (AOR) with a 95% confidence interval (CI) was used to estimate the strength of association, and statistical significance was proclaimed at a p-value < 0.05. The prevalence of diabetic microvascular complications was 21.8% (95% CI: 17.8-25.6) with diabetic neuropathy being the most common (16.8%), followed by diabetic retinopathy (4.2%), and diabetic nephropathy (2.9%). Poor glycemic control (AOR = 2.00, 95% CI: 1.01-3.98), and a history of hypertension (AOR = 2.36, 95% CI: 1.39-4.00) were positively associated with the development of diabetic microvascular complications. Conversely, being aged 41-60 years (AOR = 0.35, 95% CI: 0.18-0.68) was negatively associated with the development of these complications. About one in five patients developed at least one diabetic microvascular complication. Age, poor glycemic control, and a history of hypertension were associated with the development of these complications. Therefore, intervening to improve glycemic control and manage hypertension is crucial in preventing the onset of diabetic microvascular complications.
