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.

Glucagon-Like Peptide-1 Receptor Agonists (GLP1-RA) has been associated with cholelithiasis in a previous meta-analysis. The publication of new trials suggests the need for an update. We collected trials with GLP1-RA vs. other therapies, calculating Mantel-Haenszel odds ratio (MH-OR, 95%CI). GLP1-RA significantly increased the risk of cholelithiasis (MH-OR 1.28 [1.11, 1.48]).

Background: Concerns have been raised on the risk of lower limb amputations with SGLT-2 inhibitors. Aim of the present metanalysis is the assessment of the effect of SGLT-2inhibitors on peripheral artery disease and lower limb amputations in randomized controlled trials performed in patients with type 2 diabetes.Methods: A Medline and Embase search for "Canaglifozin" OR "Dapaglifozin" OR "Empaglifozin" OR "Ertuglifozin" OR "Ipraglifozin" OR Tofoglifozin" OR "Luseoglifozin" was performed, collecting randomized clinical trials (duration > 12 weeks) up to December 1st, 2018, comparing SGLT-2i at approved dose with placebo or other active comparators different from SGLT-2 inhibitors. Furthermore, unpublished studies were searched in the www.clinicaltrials.gov register. Separate analyses were performed for individual molecules of the class. In addition, a separate analysis was performed for placebo-controlled trials. Mantel-Haenszel odds ratio with 95% Confidence Interval (MH-OR) was calculated for all outcomes defined above.Results: A total of 27 trials fulfilling the inclusion criteria was identified. The overall incidence of peripheral artery disease was increased with SGLT-2 inhibitors (MH-OR: 1.26 [1.04, 1.52]). The increase of risk was statistically significant only with canagliflozin. MH-OR for amputation in the three cardiovascular safety trials with SGLT-2 inhibitors was 1.22 [0.59-2.52].Conclusions: At present, there is no reason to believe that empagliflozin or dapagliflozin increase the risk of either peripheral artery disease of lower limb amputations. Canagliflozin could be associated with a specific risk, which needs to be further investigated. [ABSTRACT FROM AUTHOR]

Background: Immune checkpoint inhibitors (ICI) exert their therapeutic effect by modulating the immune system and potentiating antitumor immunity. ICI have been associated with several immune-related adverse events, such as diabetes. However, no formal metaanalysis with this respect has been conducted so far. Aim of the present metaanalysis of randomized trials is to assess the effects of ICI on incident diabetes and hyperglycemia.Methods: A MEDLINE, Scopus, ISI-WOS, and Cochrane database search was performed to identify trials, enrolling patients with any form of cancer, up to April 23rd, 2019 in which ICI have been compared either with placebo or active comparators. Data were extracted from published reports or, if not available, from clinicaltrials.gov. The principal endpoints were the incidence of diabetes and cases of hyperglycemia, reported as adverse events. Mantel-Haenszel Odds Ratio with 95% Confidence Interval (MH-OR) was calculated for all outcomes. The study has been registered on PROSPERO website (CDR133927).Findings: Out of 42 trials retrieved, 40 reported information on incident diabetes or hyperglycemia. No association of ICI with incident diabetes (MH-OR 1.27 [0.66, 2.43], p = 0.47) was observed; whereas there was a trend toward an increased risk of hyperglycemia (MH-OR 1.45 [0.99, 2.13], p = 0.060), which reached statistical significance in sensitivity analyses and when analyzing separately placebo-controlled trials (MH-OR 1.95 [1.10, 3.49], p = 0.020). I2 statistics did not suggest any relevant heterogeneity for all the principal analyses performed.Interpretation: ICI treatment is associated with an increased risk of hyperglycemia, and an increase in the risk of diabetes cannot be excluded.

Aim: Observational studies and metanalyses of randomized trials on Dipeptidyl Peptidase-4 inhibitors (DPP4i) reported discordant results on the risk of pancreatitis and pancreatic cancer with this class of drugs. Aim of the present meta-analysis is the assessment of the effect of DPP4i treatment on the incidence of pancreatitis and pancreatic cancer, collecting all available evidence from randomized controlled trials. Methods Data Sources: an extensive Medline, Embase and Cochrane Database search for sitagliptin or vildagliptin or omarigliptin or saxagliptin or alogliptin or trelagliptin or anagliptin or linagliptin or gemigliptin or evogliptin or teneligliptin was performed up to up to September 30th, 2019. All trials performed on type 2 diabetes, with duration ≥24 weeks, and comparing of DPP4i with placebo or active drugs were collected. The study has been registered on PROSPERO (#153344). Mantel-Haenszel odds ratio (MH-OR) with 95% Confidence Interval (95% CI) was calculated for all outcomes defined above. Results A total of 165 eligible trials were identified. DPP-4 inhibitors were not associated with an increased risk of pancreatitis (MH-OR 1.13 [0.86, 1.47]) or pancreatic cancer (MH-OR 0.86 [0.60, 1.24]) with no significant differences across individual molecules of the class.Conclusions: available data do not support the hypothesis of an association of DPP4i treatment with pancreatitis. Present data do not suggest any association of DPP4i with pancreatic cancer, although they are insufficient to draw definitive conclusions. [ABSTRACT FROM AUTHOR]

Sodium-glucose cotransporter 2 inhibitors (SGLT2i) decreased serum uric acid in type 2 diabetes. Hyperuricemia is associated with an increased risk of nephrolithiasis. The present meta-analysis, performed on trials with duration ≥52 weeks in comparison with placebo or active comparators, suggests no effects of SGLT-2i on the risk of nephrolithiasis.
