Abstract

To evaluate the relationship between glycemic control and plasma glycated hemoglobin (HbA1c) levels in patients with type 2 diabetes mellitus (T2D) and the risk of chronic obstructive pulmonary disease (COPD). We conducted a population-based, retrospective, nested, case-control study involving 124,876 patients with DM2 from the Canary Islands, Spain. From the cohort, we selected all COPD cases and, for each case, five control subjects who were COPD free. We analyzed the association between glycemic control, HbA1c level and incident COPD. A total of 1320 incidence cases of COPD (1.06%) were identified and matched individually with 6600 controls according to age and sex. After multivariate adjustment, the COPD risk increased among patients with poor glycemic control compared to patients with good glycemic control [HbA1c levels <7% (53 mmol/mol)] (OR 1.18; 95% CI: 1.03-1.36). In comparison with patients exhibiting HbA1c levels <7% (53 mmol/mol), the risk of COPD was higher among people with HbA1c levels of 7-8% (53-64 mmol/mol) (OR 1.24; 95% CI: 1.05-1.47) and 8-9% (64-75 mmol/mol) (OR 1.31; 95% CI: 1.04-1.66). Poor glycemic control reveals a weak association with increased risk of COPD in T2D patients.

Biomarkers for Type 2 Diabetes

Biomarkers can help understand chronic diseases and assist in risk prediction for prevention and early detection of diseases. Here is the latest research on biomarkers in type 2 diabetes, a disease in which the body is unable to produce or properly use insulin.
