Pioglitazone use may be associated with a decrease in both cardiovascular and noncardiovascular mortality for patients with type 2 diabetes (T2D), according to results of an extended database cohort analysis published in BMJ Open Diabetes Research and Care.
The results suggest that these broader benefits of pioglitazone support its safe and effective use for patients with T2D.
The exploratory linked database cohort analysis pooled health and mortality data from Finland, Sweden, and the United Kingdom. The study included participants with T2D who were first prescribed pioglitazone from 2000 to 2011 (n=31,133) and matched control patients with T2D who had never been prescribed pioglitazone (n=31,133). Participants were matched for treatment stage, history of diabetes, diabetes complications, cardiovascular disease, and year of cohort entry. Mean follow-up time was 2.60 and 2.69 years in the pioglitazone and control groups, respectively.
The researchers found that the pioglitazone group had a lower cardiovascular-related and noncardiovascular-related mortality compared with the control group (adjusted hazard ratio, 0.58 [95% CI, 0.52-0.63] and 0.63 [95% CI, 0.58-0.68], respectively).
Participants in the pioglitazone group had significantly reduced risk for several cause-specific mortalities compared with control patients. The pioglitazone group had a 39% reduction for myocardial infarction-related mortality, 52% reduction for stroke-related mortality, and 40% for heart failure-related mortality compared with control patients.
The researchers stressed that this was an exploratory study and suggest further studies that test the association between pioglitazone use and patient-focused outcomes.
