Correlation of the telomere length with type 2 diabetes mellitus in patients with ischemic heart disease.

ABSTRACT:

Objective

The study aimed to explore the relationship of the telomere length with type 2 diabetes mellitus (DM) among patients with ischemic heart disease (IHD).

Method

This 2-year cross-sectional study included 130 male patients diagnosed with IHD through echocardiography and coronary angiography, wherein consecutive IHD patients with type 2 DM (65) and without type 2 DM (65) were selected. Baseline characteristics including age, gender, body mass index, and blood pressure were recorded. Laboratory investigations such as random blood sugar (RBS), fasting lipid profile, serum creatinine, and serum urea levels were measured. Quantitative real-time polymerase chain reaction was used for the measurement of the telomere length. The logistic regression analysis was used to predict the relationship of the telomere length with age and type 2 DM among patients with IHD.

Results

All the patients in the study were men, and most of them (diabetics = 22; nondiabetics = 20) were aged between 56 and 65 years. Age (p = 0.003), telomere length (p < 0.001), RBS (p < 0.001), serum creatinine (p < 0013), and serum urea (p < 0.04) were significantly higher in the diabetic subset than in the nondiabetic subset. No significant relationship was observed between age and the telomere length (p = 0.813); however, the mean telomere length was significantly high among the patients with type 2 DM than those without type 2 DM (p = 0.005). The logistic regression analysis showed that the telomere shortening (p = 0.00019) and RBS (p < 0.0001) were the significant risk factors for type 2 DM in patients with IHD.

Conclusion

The telomere shortening was significantly correlated with type 2 DM among the patients with IHD. However, multicentric studies with larger samples are required to validate the current observation.

Project description:Short telomeres have been linked to various age-related diseases. We aimed to assess the association of telomere length with incident type 2 diabetes mellitus (T2DM) in prospective cohort studies.Leucocyte relative telomere length (RTL) was measured using quantitative polymerase chain reaction in 684 participants of the prospective population-based Bruneck Study (1995 baseline), with repeat RTL measurements performed in 2005 (n = 558) and 2010 (n = 479). Hazard ratios for T2DM were calculated across quartiles of baseline RTL using Cox regression models adjusted for age, sex, body-mass index, smoking, socio-economic status, physical activity, alcohol consumption, high-density lipoprotein cholesterol, log high-sensitivity C-reactive protein, and waist-hip ratio. Separate analyses corrected hazard ratios for within-person variability using multivariate regression calibration of repeated measurements. To contextualise findings, we systematically sought PubMed, Web of Science and EMBASE for relevant articles and pooled results using random-effects meta-analysis.Over 15 years of follow-up, 44 out of 606 participants free of diabetes at baseline developed incident T2DM. The adjusted hazard ratio for T2DM comparing the bottom vs. the top quartile of baseline RTL (i.e. shortest vs. longest) was 2.00 (95% confidence interval: 0.90 to 4.49; P = 0.091), and 2.31 comparing the bottom quartile vs. the remainder (1.21 to 4.41; P = 0.011). The corresponding hazard ratios corrected for within-person RTL variability were 3.22 (1.27 to 8.14; P = 0.014) and 2.86 (1.45 to 5.65; P = 0.003). In a random-effects meta-analysis of three prospective cohort studies involving 6,991 participants and 2,011 incident T2DM events, the pooled relative risk was 1.31 (1.07 to 1.60; P = 0.010; I2 = 69%).Low RTL is independently associated with the risk of incident T2DM. To avoid regression dilution biases in observed associations of RTL with disease risk, future studies should implement methods correcting for within-person variability in RTL. The causal role of short telomeres in T2DM development remains to be determined.
