Abstract
AIMS: Diabetic ketoacidosis (DKA) associated with SGLT-2 inhibitors (SGLT-2i) is a possible adverse event. In fact, SGLT-2i are capable of stimulating the release of glucagon and ketone re-absorption in the renal tubuli, thus increasing the concentration of ketone bodies. METHODS: A Medline search for SGLT2i (dapagliflozin, empagliflozin, canagliflozin, ipragliflozin, ertugliflozin, luseogliflozin) was performed, collecting all randomized trials with a duration of treatment≥12weeks, enrolling patients with type 2 diabetes, and comparing a SGLT2i with placebo or other comparators. The principal outcome was the effect of SGLT2i on ketoacidosis as serious adverse event. RESULTS: Out of 72 trials reporting information on DKA, 9 reported at least one event of ketoacidosis; those eight trials enrolled 10,157 and 5396 in SGLT-2 inhibitors and comparator groups, respectively. No signal of increased risk for ketoacidosis was observed for SGLT2 inhibitors as a class (MH-OR [95% CI] 1.14 [0.45-2.88], p=0.78) or as individual molecule. The sensitivity analysis with continuity correction (inputing one event each in drug and comparator arms of each trial with zero events) suggested a reduced incidence of ketoacidosis in patients treated with SGLT-2 inhibitors (MH-OR 0.65 [0.47-0.90]; p=0.01). CONCLUSIONS: The results of clinical trials summarized in the present meta-analysis reassure us that, when the drug is properly prescribed, the risk of DKA is negligible.
