RESUMO
AIMS: To assess post-initiation predictors of discontinuation of sodium-glucose cotransporter-2 (SGLT2) inhibitors compared to dipeptidyl-peptidase-4 (DPP-4) inhibitors in the United Kingdom. MATERIALS AND METHODS: We conducted a comparative population-based retrospective cohort study using primary care data from the UK Clinical Practice Research Datalink (CPRD) with linked data to hospital and death records. We included new metformin users who initiated either SGLT2 inhibitors or DPP-4 inhibitors between January 2013 and October 2019. The main outcome was treatment discontinuation, defined as the first 90-day gap after the estimated treatment end date. We used a series of extended Cox models to assess which time-dependent predictors were associated with treatment discontinuation. To test if the hazard ratio of discontinuation for each predictor was statistically different between SGLT2 and DPP-4 inhibitors, an exposure-predictor interaction term was added to each model. RESULTS: There were 2550 new users of SGLT2 inhibitors and 8195 new users of DPP-4 inhibitors. Approximately 69% of SGLT2 inhibitor and 74% of DPP-4 inhibitor users had discontinued treatment by the end of follow-up. Occurrence of fractures after treatment initiation was a significant predictor of discontinuation of SGLT2 inhibitors (hazard ratio [HR] 4.13, 95% confidence interval [CI] 2.12-8.06) but not DPP-4 inhibitors (HR 0.93, 95% CI 0.79-1.11). The rate of treatment discontinuation was significantly higher for those with low estimated glomerular filtration rate and minimal contact with the healthcare system. Efficacy endpoints, such as heart failure and glycated haemoglobin level, were not associated with treatment discontinuation. CONCLUSIONS: Our findings reflect some discrepancy between the available evidence and prescribing behaviour for SGLT2 inhibitors.

AIMS: Disproportionality analysis is a common pharmacovigilance tool to detect safety signals of type 2 diabetes medications from spontaneous drug reporting databases. The aim was to demonstrate the impact of using active-comparator restricted disproportionality analysis (ACR-DA), wherein the reference group is restricted to reports with a clinically appropriate active comparator. METHODS: Using reports from the Food and Drug Administration Adverse Event Reporting System, we assessed if sodium/glucose cotransporter 2 (SGLT2) inhibitors are associated with higher reporting of 5 potential adverse events: acute kidney injury, genitourinary tract infections, diabetic ketoacidosis, fractures, and amputations. For each adverse event, we calculated the proportional reporting ratio (PRR) and adjusted reporting odds ratio (aROR [95% confidence interval, CI]) using 3 types of reference groups: no SGLT2 inhibitor (background risk reference), other diabetes drugs (therapeutic class reference), and dipeptidyl peptidase 4 inhibitors (active comparator reference). RESULTS: Based on ACR-DA, we did not detect a safety signal for acute kidney injury (PRR 0.92 [0.81-1.04]; aROR 0.78 [95% CI 0.72-0.85]) or fractures (PRR 0.44[95% CI 0.17-1.15]; aROR 0.74 [95% CI 0.61-0.91]) associated with SGLT2 inhibitors compared to dipeptidyl peptidase 4 inhibitors. However, we detected safety signals for genitourinary tract infections (PRR 2.75[2.02-3.76]; aROR 2.54[2.26-2.86], diabetic ketoacidosis (PRR 63.85[39.37-103.53; aROR 91.49[70.66-118.48]), and amputations (PRR 52.60 [19.66-140.75]; aROR 22.64 [15.32-33.42]. CONCLUSION: The use of the proposed ACR-DA to detect safety signals of type 2 diabetes medications may reduce false positive safety signals through careful selection of the comparator which is expected to reduce channelling bias.

AIM: To assess the association between SGLT-2 inhibitors initiation and genital tract infections (GTIs) among patients with type 2 diabetes. METHODS: A population-based cohort study using administrative healthcare data from Alberta, Canada, and primary care data from the UK's Clinical Practice Research Datalink (CPRD). Among new metformin users, we identified new users of SGLT-2 inhibitors and five active comparator cohorts (new users of dipeptidyl peptidase-4 (DPP-4) inhibitors, sulfonylureas (SU), glucagon-like peptide-1 receptor agonists (GLP-1 RA), thiazolidinediones (TZD) and insulin). The outcome of interest was a composite GTI outcome. In each cohort, we used high-dimensional propensity score matching to adjust for confounding and conditional Cox proportional hazards regression to estimate the hazard ratios (HR). We used random-effects meta-analysis to combine aggregate data across databases. RESULTS: The risk of GTI was higher for SGLT-2 inhibitors users compared with DPP4inhibitor users (pooled HR 2.68, 95% CI 2.19 3.28), SU users (3.29, 2.62-4.13), GLP1-RA users (2.51, 1.90-3.31), TZD users (4.17, 2.46-7.08) and insulin users (1.86, 1.27-2.73). CONCLUSION: In five comparative cohorts, SGLT-2 inhibitors initiation is associated with a higher risk of GTIs. These findings from real-world data are consistent with placebo-controlled randomized controlled trials.

Evidence from observational studies may be considered complementary to that of randomized controlled trials (RCTs), particularly when assessing rare outcomes of drug therapies. Sodium/glucose cotransporter 2 (SGLT-2) inhibitors are a novel class of antidiabetic agents that have been linked to an increased risk of diabetic ketoacidosis (DKA). We conducted a systematic review and separately meta-analyzed data from RCTs (n = 18; 2013-2019) and cohort studies (n = 7; 2017-2020) to assess the consistency of the magnitude of association between SGLT-2 inhibitors and DKA risk. We illustrate the strengths and weaknesses of the 2 designs. Results from RCTs and observational studies consistently showed almost a doubling in the risk of DKA among patients using an SGLT-2 inhibitor as compared with placebo or an active comparator. In a random-effects model, the pooled relative risk was 2.08 (95% confidence interval (CI): 1.28, 3.40) from placebo-controlled RCTs and 0.82 (95% CI: 0.25, 2.68) from active-comparator RCTs. The pooled adjusted hazard ratio from observational studies was 1.74 (95% CI: 1.28, 2.38). Notably, the 2 designs complement each other in several domains, including external and internal validity and power. This demonstrates a need for more comprehensive evidence when assessing rare adverse events for both sources.

Introduction: Older adults with dementia who are on multiple medications are more vulnerable to the use of potentially inappropriate medications (PIMs), which can significantly increase the risk of adverse events and drug-related problems. PIMs use is prevalent and varies among older adults with dementia or cognitive impairment (CI) attending memory clinics. However, the prevalence of PIMs, polypharmacy, and hyper-polypharmacy among older adults with dementia or CI who are attending memory clinics is not well understood. We will conduct a systematic review and meta-analyses to examine the overall estimate of the prevalence of the PIMs, polypharmacy, and hyper-polypharmacy use among older adults attending memory clinics, with dementia or CI. The secondary objective of this study will be to compile a list of commonly implicated PIMs and to investigate factors that may be associated with using PIMs in this population. Methods: Ovid MEDLINE, Ovid Embase, Scopus, Cochrane library, EBSCOhost CINAHL, and Ovid International Pharmaceutical Abstracts (IPA) will be systematically searched by a researcher (R.S.) with the help of a librarian (C.C.). All databases will be searched from inception to May 05, 2023. Cross-sectional, cohort, randomized clinical trials, quasi-experimental, and case-control studies will be included if they assess PIM's use among older adults with dementia and/or CI. A step-by-step guide by Pai et al. [Natl Med J India. 2004;17(2):86-95] will be followed when conducting this systematic review (S.R.). The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) checklist will be followed for reporting this SR. Conclusion: The findings from this SR/MA will identify the pooled prevalence of PIMs, providing a more precise estimate of the true prevalence of the PIMs, polypharmacy, hyper-polypharmacy in older adults with dementia or CI who are attending memory clinics at primary, secondary, or tertiary healthcare settings by considering the results of multiple studies.
RESUMO
OBJECTIVES: To examine the associations between COVID-19 pandemic waves (1-4) and prevalent antipsychotic, antidepressant, benzodiazepine, anticonvulsant, and opioid use among assisted living (AL) residents, by setting (dementia care vs other). DESIGN: Population-based, repeated cross-sectional study. SETTING AND PARTICIPANTS: Linked clinical and health administrative databases for residents of all publicly subsidized AL homes (N = 256) in Alberta, Canada, examined from January 2018 to December 2021. Setting-specific quarterly cohorts of residents were derived for pandemic (starting March 1, 2020) and comparable historical (2018/2019 combined) periods. METHODS: The quarterly proportion of residents dispensed an antipsychotic, antidepressant, benzodiazepine, anticonvulsant, or opioid was examined for each setting and period. Log-binomial generalized estimating equations models estimated prevalence ratios (PR) for period (pandemic vs historical quarterly periods), setting (dementia care vs other AL), and period-setting interactions. RESULTS: On March 1, 2020, there were 2874 dementia care and 6611 other AL residents (mean age 82.4 vs 79.9 years, 68.2% vs 66.1% female, 93.5% vs 42.6% with dementia, respectively). Antipsychotic use increased during waves 2 to 4 for residents of both settings, but this increase was significantly greater for dementia care than other AL residents during waves 3 and 4 (eg, wave 3, PR 1.21, 95% CI 1.14-1.27 vs PR 1.12, 95% CI 1.07-1.17, interaction term P = .029). In both settings, there was a significant but modest increase in antidepressant use and a significant decrease in benzodiazepine use during several pandemic waves. For other AL residents only, there was a small statistically significant increase in anticonvulsant use during waves 2 to 4. No significant pandemic effect was observed for prevalent opioid use in either setting. CONCLUSIONS AND IMPLICATIONS: The persistence of the pandemic-associated increase in antipsychotic, antidepressant, and anticonvulsant use in AL residents, and greater increase in antipsychotic use for dementia care settings, raises concerns about the attendant risks for residents, especially those with dementia.

OBJECTIVES: Landmark clinical trials have shown the sodium-glucose cotransporter-2 (SGLT-2) inhibitors to have cardiorenal benefits beyond their glucose-lowering effect. Clinical guidelines now recommend their use in patients with chronic kidney disease or heart failure, with or without type 2 diabetes, potentially affecting prescribing patterns among physician specialties. METHODS: Using monthly projected total retail dispensed prescription data from IQVIA's CompuScript database, we assessed trends in prescribing SGLT-2 inhibitors among 6 prescriber specialities from 2015 to 2021 in Canada. We assessed these trends at the class, agent, and dose level using joinpoint regression. RESULTS: From 2015 to 2021, the projected total retail dispensed prescriptions of SGLT-2 inhibitors from all prescribers increased. Relative to other prescribers, >60% of SGLT-2 inhibitor prescriptions were written by general practitioners or family physicians. The percentage of prescriptions from endocrinologists decreased (average annual percent change: mean, -10.8; 95% confidence interval [CI], -12.2% to -9.4%), whereas a dramatic increase was observed for cardiologists (mean, 44.1%, 95% CI, 32.9 to 56.2). The percentage from nephrologists also increased, albeit not statistically significant (mean, 12.4; 95% CI, -0.5 to 27.1). Significant changes in the agent and dose of SGLT-2 inhibitor prescribed were also observed among cardiologists and nephrologists. CONCLUSIONS: Between 2015 and 2021, there was a steady increase in the proportion of SGLT-2 inhibitor prescriptions from cardiologists and nephrologists, reflecting emerging evidence and guideline recommendations.

OBJECTIVE: Severe hypoglycemia is associated with an increased risk of dementia. We examined if the association is consistently present in mid- and late-life hypoglycemia. RESEARCH DESIGN AND METHODS: Using health care data from Population Data BC, we created a base cohort of patients age ≥40 years with incident type 2 diabetes. Exposure was the first occurrence of severe hypoglycemia (hospitalization or physician visit). We assessed exposure versus no exposure in mid- (age 45-64 years) and late-life (age 65-84 years) cohorts. Index date was the later of the 45th birthday (midlife cohort), 65th birthday (late-life cohort), or diabetes diagnosis. Those with hypoglycemia or dementia before the index date were excluded. Patients were followed from index date until dementia diagnosis, death, emigration, or 31 December 2018. Exposure was modeled as time dependent. We adjusted for confounding using propensity score weighting. Dementia risk was estimated using cause-specific hazards models with death as a competing risk. RESULTS: Of 221,683 patients in the midlife cohort, 1,793 experienced their first severe hypoglycemic event. Over a median of 9.14 years, 3,117 dementia outcomes occurred (32 among exposed). Of 223,940 patients in the late-life cohort, 2,466 experienced their first severe hypoglycemic event. Over a median of 6.7 years, 15,997 dementia outcomes occurred (158 among exposed). The rate of dementia was higher for those with (vs. without) hypoglycemia in both the mid- (hazard ratio 2.85; 95% CI 1.72-4.72) and late-life (2.38; 1.83-3.11) cohorts. CONCLUSIONS: Both mid- and late-life hypoglycemia were associated with approximately double the risk of dementia, indicating the need for prevention throughout the life course of those with diabetes.

BACKGROUND: Previous studies have shown hypoglycaemia to be associated with an increased risk of dementia; however, there are several design challenges to consider. The objective of this study is to assess the association between hypoglycaemia and dementia while addressing these challenges using a lag period, exposure density sampling (EDS) and inverse probability of treatment weighting (IPTW). METHODS: This was a population-based cohort using data (1996-2018) from British Columbia, Canada. From a cohort of incident type 2 diabetes patients aged 40-70 years, we created a dynamic sub-cohort of hypoglycaemia-exposed (≥1 episode requiring hospitalization or a physician visit) and unexposed individuals using EDS, in which four unexposed individuals per one exposed were randomly selected into risk sets based on diabetes duration and age. Follow-up was until dementia diagnosis, death, emigration or 31 December 2018. Those diagnosed with dementia within 2 years of follow-up were censored. We adjusted for confounding using IPTW and estimated the hazard ratio (HR, 95% CI) of dementia using weighted conditional cause-specific hazards risk models with death as a competing risk. RESULTS: Among 13â970 patients with incident type 2 diabetes, 2794 experienced hypoglycaemia. There were 329 dementia events over a median (interquartile range: IQR) follow-up of 5.03 (5.7) years. IPTW resulted in well-balanced groups with weighted incidence rates (95% CI) of 4.59 (3.52, 5.98)/1000 person-years among exposed and 3.33 (2.58, 3.88)/1000 person-years among unexposed participants. The risk of dementia was higher among those with hypoglycaemia (HR, 1.83; 95% CI 1.31, 2.57). CONCLUSIONS: After addressing several methodological challenges, we showed that hypoglycaemia contributes to an increased risk of all-cause dementia among patients with type 2 diabetes.

OBJECTIVE: Evidence of an increased dementia risk with insulin use in type 2 diabetes is weakened by confounding by indication and disease severity. Herein we reassess this association, while accounting for confounding through design and analysis. RESEARCH DESIGN AND METHODS: Using administrative health care data from British Columbia, Canada, we identified patients diagnosed with type 2 diabetes in 1998-2016. To adjust for confounding by diabetes severity through design, we compared new users of insulin to new users of a noninsulin class, both from a restricted cohort of those who previously received two noninsulin antihyperglycemic classes. We further adjusted for confounding using 1) conventional multivariable adjustment and 2) inverse probability of treatment weighting (IPTW) based on the high-dimensional propensity score algorithm. The hazard ratio [HR] (95% CI) of dementia was estimated using cause-specific hazards models with death as a competing risk. RESULTS: The analytical comparative cohort included 7,863 insulin versus 25,230 noninsulin users. At baseline, insulin users were more likely to have worse health indicators. A total of 78 dementia events occurred over a median (interquartile range) follow-up of 3.9 (5.9) years among insulin users, and 179 events occurred over 4.6 (4.4) years among noninsulin users. The HR (95% CI) of dementia for insulin use versus noninsulin use was 1.68 (1.29-2.20) before adjustment and 1.39 (1.05-1.86) after multivariable adjustment, which was further attenuated to 1.14 (0.81-1.60) after IPTW. CONCLUSIONS: Among individuals with type 2 diabetes previously exposed to two noninsulin antihyperglycemic medications, no significant association was observed between insulin use and all-cause dementia.

Background: Athletes with type 1 diabetes (T1D) face unique challenges to maintain optimal glucose levels and therefore require tailored guidance from their healthcare providers. Herein, we aim to summarize and compare recommendations targeted at T1D management in athletes in commonly used clinical practice guidelines and topical position statements. The objective is to assess if the available recommendations are comprehensive enough for athletes to apply to high-performance sport. Methods: From seven clinical practice guidelines and positions statements, we identified recommendations relevant to athletes with T1D, based on a specific hierarchy. For included recommendations, we extracted relevant information including the year of publication, author(s), chapter name or number, text for the recommendation, and level of evidence. Based, on the clinical topic covered, we grouped included recommendations to five themes. Results: We screened a total of 126 recommendations, of which 60 recommendations were included. The National Athletic Trainers' Association provided the highest number of recommendations relevant to athletes with T1D (n = 27). Insulin modifications was the most covered clinical theme (n = 18). The 2018 Diabetes Canada and 2021 American Diabetic Association guidelines linked recommendations directly with levels and grades of evidence. None of the recommendations had level 1 or grade A evidence. Three recommendations from Diabetes Canada reported level 2, grade B evidence. American Diabetic Association reported 1 recommendation with grade B evidence, and 2 recommendations with grade C evidence. Conclusions: There is an opportunity for expansion of clinical practice guidelines to increase the depth and breadth of recommendations for high performance athletes with T1D.
RESUMO
INTRODUCTION: An increased risk of myopathy due to a potential interaction between sodium glucose co-transporter-2 inhibitors (SGLT-2i) and HMG-CoA reductase inhibitors (statins) has been suggested by case reports. OBJECTIVE: We aimed to assess if the reporting of myopathy is disproportionally higher among people using both SGLT-2i and statins compared to using either SGLT-2i or statins alone. METHODS: We conducted a disproportionality analysis using data from the US Food and Drug Administration Adverse Event Reporting System (FAERS). We included reports with at least one antihyperglycemic agent. We compared the proportion of myopathy cases to non-cases between those not using SGLT-2i or statins, using SGLT-2i only, statins only, or both. We calculated the reporting odds ratio and 95% confidence interval. We further stratified by individual SGLT-2i and selected statins (rosuvastatin or atorvastatin). RESULTS: We included 688,388 reports with at least one antihyperglycemic agent recorded, of which 9.80% had at least one SGLT-2i agent. Among all included reports, there were a total of 2202 myopathy cases with the majority, 61.26%, occurring among those using statins alone and only 2.72% of myopathy cases were among those using both SGLT-2i and statins together. Reporting of myopathy was not disproportionally higher among those reporting the use of SGLT-2i with statins (reporting odds ratio 2.95, 95% confidence interval 2.27-3.85) compared to statins alone (reporting odds ratio 6.41, 95% confidence interval 5.86-7.02). CONCLUSIONS: Reports of myopathy were not disproportionally higher among those using SGLT-2i with statins compared to SGLT-2i or statins alone at the class level. Further observational studies may be needed to better assess this interaction at the agent level.

AIM: We assessed the risk of all-cause hospitalization and all-cause death associated with the use of Sodium Glucose Cotransporter-2 inhibitors (SGLT2i). METHODS: Population-based propensity scores-matched cohort study of new users of metformin who subsequently initiated SGLT2i compared to those who initiated dipeptidyl peptidase-4 inhibitors (DPP4i) (primary comparison), sulfonylureas, thiazolidinediones, GLP1-Receptors agonists, and insulin, respectively. Alberta (Canada) health administrative data and United Kingdom Clinical Practice Research Datalink (CPRD) data were used to assess the study outcomes. Conditional Cox regressions were performed to assess the risk of each outcome, separately for each dataset and then results were combined using random-effects meta-analysis. RESULTS: For SGLT2i versus DPP4i, 7531 and 1647 SGLT2i-DPP4i matched pairs were analyzed in Alberta and CPRD data respectively. The mean age of patients was 56 and 57 years, and 39% and 43% were females, respectively in Alberta and CPRD cohorts. Compared with DPP-4-i, SGLT2i use was associated with a significant lower risk of all-cause hospitalization (combined hazard ratio (HR): 0.84, 95% confidence interval (95%CI): 0.75-0.95), and all-cause death (0.56, 0.38-0.83). SGLT2i use was also associated with a significant lower risk of all-cause hospitalization and all-cause death when compared to sulfonylureas (HRs: 0.80, 95%CI: 0.71-0.90 and 0.56, 95%CI: 0.38-0.82, respectively) and insulin (HRs: 0.55, 95%CI: 0.41-0.74, and 0.33, 95%CI: 0.24-0.46, respectively). CONCLUSIONS: SGLT2i initiation was associated with a decreased risk of all-cause hospitalization and all-cause death when compared to DPP4i, sulfonylureas, and insulin.

OBJECTIVES: Sodium-glucose cotransporter-2 (SGLT2) inhibitor-induced glycosuria is hypothesized to increase the risk of urinary tract infections (UTIs). We assessed the risk of UTIs associated with SGLT2 inhibitor initiation in type 2 diabetes. METHODS: We conducted a population-based cohort study using primary care data from the United Kingdom's Clinical Practice Research Datalink (CPRD) and administrative health-care data from Alberta, Canada. From a base cohort of new metformin users, we constructed 5 comparative cohorts, wherein the exposure contrast was defined as new use of SGLT2 inhibitors or 1 of 5 active comparators: dipeptidylpeptidase-4 (DPP-4) inhibitors, sulfonylureas (SU), glucagon-like peptide-1 receptor agonists (GLP-1 RA), thiazolidinediones (TZD) and insulin. We defined a composite UTI outcome based on hospitalizations or physician visit records. For each comparative cohort, we used high-dimensional propensity score matching to adjust for confounding and Cox proportional hazards regression to estimate the hazard ratios (HRs) in each database. We meta-analyzed estimates using a random-effects model. RESULTS: SGLT2 inhibitor use was not associated with a higher risk of UTI compared with DPP-4 inhibitors (pooled HR, 1.08; 95% confidence interval [CI], 0.89 to 1.30), SU (pooled HR, 1.08; 95% CI, 0.90 to 1.30), GLP-1 RA (pooled HR, 0.81; 95% CI, 0.61 to 1.09) or TZD (pooled HR, 0.81; 95% CI, 0.55 to 1.19). The risk of UTI was lower compared with insulin (pooled HR, 0.74; 95% CI, 0.63 to 0.87). The risk of UTI did not differ based on the SGLT2 inhibitor agent or dose. Last, SGLT2 inhibitor initiation was not associated with an increased risk of UTI recurrence. CONCLUSION: SGLT2 inhibitor use is not associated with an increased risk of UTIs, compared with other antidiabetic agents.

BACKGROUND: Sodium-glucose cotransporter-2 (SGLT-2) inhibitors are a novel class of pharmacotherapeutics for type 2 diabetes management that work by reducing renal reabsorption of glucose. Ipragliflozin is a potent, selective SGLT-2 inhibitor used for the management of type 2 diabetes. OBJECTIVE: The primary aim of this review is to summarize the available evidence on the efficacy and safety of ipragliflozin for the management of type 2 diabetes. We also review the discovery, pharmacokinetic, and pharmacodynamic profile of ipragliflozin. METHODS: To inform our review, we searched MEDLINE, International Pharmaceutical Abstracts, and Embase to identify relevant papers to ipragliflozin use in type 2 diabetes. Clinical trial registries were also searched. RESULTS: Findings from randomized clinical trials demonstrate that compared to placebo, ipragliflozin significantly reduces glucose as measured via Hemoglobin A1c and fasting plasma glucose levels. Ipragliflozin is also associated with weight reduction and an improvement in some, but not all, cardiovascular risk markers. Ipragliflozin has a favourable safety profile with a low risk of hypoglycemia and the rates of common adverse events are not significantly different than placebo. Limited data are available to assess rare and long-term adverse effects. CONCLUSION: Current evidence shows that ipragliflozin is an effective therapeutic option for the management of glucose control in type 2 diabetes. However, no cardiovascular outcome trials have been conducted to date. Real-world observational studies are still needed to accurately capture any possible rare or long-term adverse events.

BACKGROUND: Multiple published quantitative systematic reviews have reported on adverse events associated with the use of sodium glucose co-transporter 2 (SGLT-2) inhibitors in patients with type 2 diabetes mellitus. AIMS: To summarize and appraise the quality of evidence from quantitative systematic reviews assessing adverse events of SGLT-2 inhibitors. METHODS: We searched PubMed, EMBASE and the Cochrane Library for quantitative systematic reviews assessing SGLT-2 inhibitor safety. Two reviewers extracted data and assessed methodological quality using the Assessment of Multiple Systematic Reviews 2 (AMSTAR 2) tool. Main outcomes included pooled and single study point estimaates (in the absence of pooled estimates) with corresponding 95% confidence intervals (CIs) of SGLT-2 inhibitors versus placebo or active comparators for genitourinary infections, volume depletion, acute kidney injury, bone fractures, diabetic ketoacidosis, lower limb amputations, cancers, and other notable adverse events. RESULTS: Out of 1289 citations screened, 47 reviews assessed SGLT-2 inhibitor safety, of which 35 were of low quality. Canagliflozin, dapagliflozin and empagliflozin were consistently associated with an increased risk of genital tract infections versus placebo (point estimates ranged from 2.5 to 9.8) and other antihyperglycemic agents (point estimates ranged from 2.7 to 12.0). Canagliflozin and dapagliflozin were associated with an increased risk of diabetic ketoacidosis. Canagliflozin was the only agent associated with an increased amputation risk; however, this was driven by results from a single trial program. Dapagliflozin was the only agent that exhibited a statistically significant increased risk of urinary tract infections. Empagliflozin was associated with a statistically significant increased risk of bladder cancer; however, this finding was susceptible to detection bias. None of the agents were associated with a statistically significant increased risk of acute kidney injury, or bone fractures compared to placebo or mixed (active or placebo) comparators. Upper 95% CI limits do not rule out clinically meaningful outcomes. CONCLUSION: The majority of quantitative systematic reviews reporting on adverse events of SGLT-2 inhibitors were of low methodological quality. Despite almost 50 quantitative systematic reviews published on the safety of SGLT-2 inhibitors, clinicians are still left uncertain of the risks of important adverse effects. PLAIN LANGUAGE SUMMARY: SGLT-2 iInhibitor side effects: overview of reviews Many published systematic reviews have reported on side effects associated with the use of sodium glucose co-transporter 2 (SGLT-2) inhibitors in patients with type 2 diabetes. We aimed to summarize and appraise the quality of evidence from quantitative systematic reviews assessing side effects of SGLT-2 inhibitors. Using the Assessment of Multiple Systematic Reviews 2 (AMSTAR 2) tool, two authors extracted data and assessed the methods of included reviews. Main outcomes included reported pooled and single study point estimates for several SGLT-2 inhibitor side effects such as genital infections, bone fractures, lower limb amputations, increased blood acidity, among others. Of the reviews included in our study, 35 of the 47 reviews assessed were of low quality. Canagliflozin and dapagliflozin were associated with an increased risk of blood acidity in a 2020 review. Canagliflozin was the only agent associated with an increased amputation risk; however, this was driven by results from a single trial program. Dapagliflozin was the only agent that exhibited a significantly increased risk of urinary tract infections. Empagliflozin was associated with an increased risk of bladder cancer; however, this finding was susceptible to bias. None of the agents were associated with an increased risk of kidney injury or bone fractures.
RESUMO
INTRODUCTION: To assess the comparative effectiveness and safety of renal-related outcomes associated with sodium-glucose cotransporter-2 inhibitors (SGLT2-i) initiation among patients with type 2 diabetes using real-world data. RESEARCH DESIGN AND METHODS: We conducted a population-based cohort study using administrative healthcare data from Alberta (AB), Canada and primary care data from the Clinical Practice Research Datalink (CPRD), UK. From a cohort of new metformin users, we identified initiators of a SGLT2-i or dipeptidyl peptidase-4 inhibitor (DPP4-i) between January 1, 2014 and March 30, 2018 (AB) or between January 1, 2013 and November 29, 2018 (CPRD). Initiators of an SGLT2-i or DPP4-i were followed until death, disenrolment, therapy discontinuation, or study end date. The effectiveness outcome was renal disease progression, defined as a composite of new-onset macroalbuminuria, serum creatinine doubling with estimated glomerular filtration rate of ≤45 mL/min/1.73 m2, renal replacement therapy, hospital admission or death from renal causes. The safety outcome was hospitalization due to acute kidney injury (AKI). We adjusted for confounding using high-dimensional propensity score matching and estimated HRs using Cox proportional hazards regression. Aggregate data from each database were combined by random-effects meta-analysis. RESULTS: Among the 29 465 included patients (20 564 AB, 8901 CPRD), 37.5% were new SGLT2-i users in AB and 21.3% in CPRD. Compared with DPP4 initiators, SGLT2-i initiators were associated with a reduced risk of renal disease progression (pooled HR 0.79, 95% CI 0.62 to 1.00); however, there was no significant difference in the risk of AKI (pooled HR 0.89, 95% CI 0.58 to 1.36). These findings were consistent with other exposure definitions and antidiabetic comparators. CONCLUSIONS: Our findings support a renoprotective effect of SGLT2-i without an increased risk of AKI, compared with clinically relevant active comparators.

AIMS: To summarize reported cancer events associated with SGLT-2 inhibitors used in patients with type 2 diabetes mellitus, as well as assess the quality of included reviews. MATERIALS AND METHODS: In May 2019, we searched PubMed, Embase and the Cochrane Library for quantitative systematic reviews assessing the safety of SGLT-2 inhibitors. Data were abstracted using a standardized form, and methodological quality was assessed using the AMSTAR 2 tool. Main outcome measures included total cancer events and specific cancers such as breast cancer, bladder cancer, gastrointestinal cancer, prostate cancer, respiratory cancer, renal cancer and skin cancer. Pooled treatment effects from included reviews were summarized for SGLT-2 inhibitors as a class and for individual SGLT-2 inhibitors commonly used worldwide (canagliflozin, dapagliflozin and empagliflozin). RESULTS: We screened 1248 unique citations, of which eight quantitative systematic reviews meta-analysed results from studies reporting the association between an SGLT-2 inhibitor and any cancer. Only one review was rated as high quality according to AMSTAR 2 assessment. In total, data from 170 cancer-related point estimates (PE) were reported. As a class, SGLT-2 inhibitors were not associated with an increased risk of any cancer event versus placebo and active comparators. Most point estimates (7/143) were nonsignificant for individual cancers except for two associations. Empagliflozin was associated with an increased risk of bladder cancer versus placebo and active comparators in two reviews, while canagliflozin appeared protective for gastrointestinal cancer versus placebo and active comparators in one review. CONCLUSIONS: It appears that SGLT-2 inhibitors are not associated with an increased risk of total cancer or specific cancers in patients with type 2 diabetes. However, higher quality evidence is needed to derive confident conclusions.
