[Which place for thiazide and thiazide-like diuretics in patients with type 2 diabetes ?].

The use of thiazides as antihypertensive agents has been challenged because associated metabolic adverse events, including new-onset diabetes. However, these metabolic disturbances are less marked with low-dose of hydrochlorothiazide and with thiazide-like diuretics such as chlorthalidone and indapamide. In post hoc analyses of subgroups of patients with hypertension and type 2 diabetes, thiazide(-like) diuretics resulted in a significant reduction in cardiovascular events, all-cause mortality and hospitalization for heart failure compared to placebo. Furthermore, they were shown to be non-inferior to other antihypertensive agents, including blockers of the renin-angiotensin system in diabetic patients without albuminuria. Benefits attributed to thiazide(-like) diuretics (especially at low dose) in terms of cardiovascular protection outweigh the risk of worsening glucose control and inducing other metabolic disorders in patients with type 2 diabetes. Thus low dose thiazide(-like) drugs still play a major role in the treatment of hypertension in patients with type 2 diabetes.
