Abstract

Aims/hypothesis

Recently, safety data signalled an increased risk of amputations in people taking canagliflozin, a sodium−glucose cotransporter 2 (SGLT2) inhibitor. If this side effect is due to drug-induced hypovolaemia, diuretics should also increase that risk. The aim of this study was to analyse the association between diuretic use and the risk of lower limb events (LLEs) in people with type 2 diabetes.

Methods

SURDIAGENE (SUivi Rénal, DIAbète de type 2 et GENEtique) is a prospective observational cohort that includes people with type 2 diabetes enrolled from 2002 to 2012 and followed-up until onset of LLE, death or 31 December 2015, whichever came first. Primary outcome was the first occurrence of LLE, a composite of lower limb amputation (LLA) and lower limb revascularisation (LLR). The rates of primary outcome were compared between participants taking and not taking diuretics at baseline in a Cox-adjusted model.

Results

At baseline, of the 1459 participants included, 670 were taking diuretics. In participants with and without diuretics, the mean ages were 67.1 and 62.9 years and 55.8% and 59.8% were men, respectively. During a median follow-up of 7.1 years, the incidence of LLE was 1.80 per 100 patient-years in diuretic users vs 1.00 in non-users (p < 0.001). The HR for LLE in users vs non-users was 2.08 (95% CI 1.49, 2.93), p < 0.001. This association remained significant in a multivariable-adjusted model (1.49 [1.01, 2.19]; p = 0.04) and similar after considering death as a competing risk (subhazard ratio 1.89 [1.35, 2.64]; p < 0.001). When separated, LLA but not LLR, was associated with the use of diuretics: 2.01 (1.14, 3.54), p = 0.02 and 1.05 (0.67, 1.64), p = 0.84, respectively, in the multivariable-adjusted model.

Conclusions/interpretation

Among people with type 2 diabetes treated with diuretics, there was a significant increase in the risk of LLE, predominantly in the risk of LLA.
