RESUMO

Nesfatin concentrations are positively correlated with beta cell function. However, it is unclear whether diet composition mediates this relationship. We recruited 27 overweight individuals who practiced Orthodox fasting (OF), a subset of the Mediterranean diet (MedDiet), for 7 weeks. Fourteen overweight people who practiced 16:8 time-restricted eating served as control group. Anthropometric parameters, biochemical data and adipokine levels were evaluated at baseline and after the end of the diet period (7 weeks from baseline). Subsequently, participants were asked to return to their usual eating plans, and an additional evaluation was performed 5 weeks after the end of the research diets (12 weeks from baseline). We observed a significant and negative correlation between HOMA-B and nesfatin values at 12 weeks, only in the OF group (r = -0.455, p = 0.01). In conclusion, returning to normal eating habits after 7 weeks of strict adherence to MedDiet affects the homeostatic balance between insulin secretion and nesfatin.

RESUMO

Over the last few years, given the increase in the incidence and prevalence of both type 2 diabetes mellitus (T2DM) and heart failure (HF), it became crucial to develop guidelines for the optimal preventive and treatment strategies for individuals facing these coexisting conditions. In patients aged over 65, HF hospitalization stands out as the predominant reason for hospital admissions, with their prognosis being associated with the presence or absence of T2DM. Historically, certain classes of glucose-lowering drugs, such as thiazolidinediones (rosiglitazone), raised concerns due to an observed increased risk of myocardial infarction (MI) and cardiovascular (CV)-related mortality. In response to these concerns, regulatory agencies started requiring CV outcome trials for all novel antidiabetic agents [i.e., dipeptidyl peptidase-4 inhibitors (DPP-4 inhibitors), glucagon-like peptide-1 receptor agonists (GLP-1 RAs), and sodium-glucose cotransporter-2 inhibitors (SGLT2is)] with the aim to assess the CV safety of these drugs beyond glycemic control. This narrative review aims to address the current knowledge about the impact of glucose-lowering agents used in T2DM on HF prevention, prognosis, and outcome.

RESUMO

Sodium-glucose co-transporter 2 inhibitors (SGLT2i) have emerged as a promising therapeutic option for hyperglycemia and its complications. However, metformin remains the first-line pharmacological treatment in most algorithms for type 2 diabetes (T2D). Although metformin is generally believed to exert positive effects on cardiovascular (CV) outcomes, relevant data are mainly observational and potentially overinterpreted. Yet, it exerts numerous pleiotropic actions that favorably affect metabolism and diabetes comorbidities. CV outcome trials have demonstrated cardiorenal protection with SGLT2i among people at high CV risk and mostly on concomitant metformin therapy. However, post hoc analyses of these trials suggest that the cardiorenal effects of gliflozins are independent of background treatment and consistent across the full spectrum of CV risk. Considering the importance of addressing hyperglycemia as a means of preventing diabetic complications and significant knowledge gaps, particularly regarding the cost-effectiveness of SGLT2i in drug-naïve populations with T2D, the position of metformin in the management of people with diabetes at low CV risk remains solid for the moment. On the other hand, available evidence-despite its limitations-suggests that specific groups of people with T2D, particularly those with heart failure and kidney disease, could probably benefit more from treatment with SGLT2i. This narrative mini-review aims to discuss whether current evidence justifies the use of SGLT2i as the first-line treatment for T2D.

RESUMO

BACKGROUND: Myasthenia gravis (MG) is a rare autoimmune disorder affecting the neuromuscular junction (NMJ). Here, we investigate the genetic architecture of MG via a genome-wide association study (GWAS) of the largest MG data set analysed to date. METHODS: We performed GWAS meta-analysis integrating three different data sets (total of 1401 cases and 3508 controls). We carried out human leucocyte antigen (HLA) fine-mapping, gene-based and tissue enrichment analyses and investigated genetic correlation with 13 other autoimmune disorders as well as pleiotropy across MG and correlated disorders. RESULTS: We confirmed the previously reported MG association with TNFRSF11A (rs4369774; p=1.09×10-13, OR=1.4). Furthermore, gene-based analysis revealed AGRN as a novel MG susceptibility gene. HLA fine-mapping pointed to two independent MG loci: HLA-DRB1 and HLA-B. MG onset-specific analysis reveals differences in the genetic architecture of early-onset MG (EOMG) versus late-onset MG (LOMG). Furthermore, we find MG to be genetically correlated with type 1 diabetes (T1D), rheumatoid arthritis (RA), late-onset vitiligo and autoimmune thyroid disease (ATD). Cross-disorder meta-analysis reveals multiple risk loci that appear pleiotropic across MG and correlated disorders. DISCUSSION: Our gene-based analysis identifies AGRN as a novel MG susceptibility gene, implicating for the first time a locus encoding a protein (agrin) that is directly relevant to NMJ activation. Mutations in AGRN have been found to underlie congenital myasthenic syndrome. Our results are also consistent with previous studies highlighting the role of HLA and TNFRSF11A in MG aetiology and the different risk genes in EOMG versus LOMG. Finally, we uncover the genetic correlation of MG with T1D, RA, ATD and late-onset vitiligo, pointing to shared underlying genetic mechanisms.

RESUMO

We prospectively assessed changes in free 25-hydroxyvitamin D [25(OH)D] and vitamin D binding protein (VDBP) among overweight adults who followed a pescatarian Orthodox intermittent fasting regimen (n = 59) and controls who followed a low-fat 12:12 diet (n = 46). Total and free 25(OH)D, parathyroid hormone, VDBP, anthropometric data, and amino acid intake were evaluated in both groups at three time points: at baseline, 7 weeks after diet implementation, and 5 weeks after participants returned to their usual eating habits (12 weeks from baseline). An increase in amino acid intake between baseline and 12 weeks was independently correlated with higher free 25(OH)D values at 12 weeks for both groups. Our findings suggest that diet can affect free 25(OH)D concentrations, through variations in amino acid intake, independently of exposure to sunlight, providing novel mechanistic insights into the future planning of vitamin D supplementation strategies. However, this hypothesis needs to be tested in larger studies.

RESUMO

The worldwide incidence of type 1 diabetes mellitus (T1DM) has increased in recent decades. The reasons behind this phenomenon are not yet fully understood. Early life infections, prenatal and perinatal factors, and diet composition have been associated with the triggering of autoimmunity and the risk of presentation of T1DM. However, the rapid increase in new cases of the disease raises the hypothesis that lifestyle factors, which have traditionally been associated with type 2 diabetes, such as obesity and unhealthy eating patterns could also play a role in the genesis of autoimmune diabetes. This article aims to highlight the changing epidemiology of T1DM and the importance of properly recognizing the environmental factors behind it, as well as the connections with the pathogenesis of the disorder and the need to prevent or delay T1DM and its long-term complications.

RESUMO

Thyroid disorders (TD) and diabetes mellitus (DM) are the two endocrinopathies with the highest prevalence in the general population that frequently coexist. Thyroid dysfunction is more common in people with type 2 diabetes mellitus (T2DM) compared to normoglycemic individuals. Untreated TD can impair glycemic control, increasing the risk of diabetes complications. Hyperinsulinemia can affect the morphology of the thyroid gland by promoting the proliferation of thyroid tissue and increasing the size of thyroid nodules. Metformin can confer benefits in both endocrinopathies, while other antidiabetics, such as sulfonylureas, can negatively affect thyroid function. Animal and human observational data suggest an increased risk of medullary thyroid carcinoma after treatment with glucagon-like peptide-1 receptor agonists. However, randomized trials have so far been reassuring. Furthermore, some observational studies suggest an association between thyroid cancer and T2DM, especially in women. This narrative review aims to shed light on the epidemiological, pathophysiological, and clinical aspects of the interplay between TD and T2DM. Taking into account the important clinical implications of the coexistence of T2DM and TD, proper screening and management strategies are needed for both endocrinopathies to ensure optimal patient care.

RESUMO

Hepatocellular carcinoma (HCC) occurs in the setting of prolonged liver inflammation, hepatocyte necrosis and regeneration in patients with cirrhosis. Despite the progress made in the medical management of the disorder during the past decades, the available pharmacological options remain limited, leading to poor survival rates and quality of life for patients with HCC. Sodium-glucose cotransporter 2 inhibitors (SGLT2) originally emerged as drugs for the treatment of hyperglycemia; however, they soon demonstrated important extra-glycemic properties, which led to their evaluation as potential treatments for a wide range of non-metabolic disorders. Evidence from animal studies suggests that SGLT2i have the potential to modulate molecular pathways that affect hallmarks of HCC, including inflammatory responses, cell proliferation, and oxidative stress. The impressive benefits of neurohormonal modulation observed with SGLT2i in congestive heart failure set the stage for human trials in cirrhotic ascites. However, future studies need to evaluate several aspects of the benefit to risk ratio of such a therapeutic strategy, including the co-administration with antineoplastic agents and diuretics, infections, use in hospitalized individuals, renal safety and hypovolemia. In this narrative review, we discuss the putative role of SGLT2i in the treatment of patients with HCC, starting with the mechanisms that could justify a possible benefit and ending with potential clinical implications and areas for future research.

RESUMO

The exact mechanisms mediating the metabolic effects of Orthodox fasting remain unclear. Plasma adiponectin, biochemical and anthropometrical data were evaluated in 55 Orthodox fasters (OF) and 42 time-restricted eating controls (all women, mean age 47.8 years) at three time points: baseline, end of the dietary intervention (7 weeks) and 5 weeks after participants returned to their typical dietary habits (12 weeks from baseline). In the OF group, there was an increase in adiponectin values at 12 weeks compared with baseline (9815.99 vs 8983.52 mg/ml, p = 0.02) and a reduction in body fat mass between baseline and 12 weeks (35.44 vs 32.17%, p = 0.004) and between 7 and 12 weeks (35.33 vs 32.17%, p = 0.003). In the same group, an inverse correlation between adiponectin and waist circumference values was observed over the entire study period. Our results provide novel evidence that Orthodox fasting has favourable metabolic effects related to improved adiponectin concentrations.

RESUMO

BACKGROUND: Latent autoimmune diabetes in adults (LADA) is characterised by pathophysiological and clinical heterogeneity. Hence, the optimal treatment strategy for this type of diabetes remains a clinical challenge. AIM: To discuss the potential of a modern therapeutic approach for LADA in the context of the novel findings of cardiovascular outcomes trials and stress the controversies surrounding LADA and the barriers in the effective management of people with this type of diabetes. METHODS: We performed a literature search in major biomedical databases in order to retrieve relevant literature. The results of key studies, along with the authors' clinical experience and perspective, are summarised and discussed in this narrative, mini review article. RESULTS: Insulin remains the primary treatment choice in individuals with low C-peptide levels. Although cardiovascular outcomes trials have mainly recruited participants with type 2 diabetes, recent data suggest that the cardiorenal protective properties of the new therapies are even present in people without diabetes and thus, the extrapolation of their results on LADA individuals sounds reasonable. Therefore, sodium-glucose co-transporter 2 inhibitors (SGLT2is) and glucagon-like peptide-1 receptor agonists should be considered for the management of people with preserved insulin production being at high cardiovascular risk. The risk of diabetic ketoacidosis with SGLT2is requires increased vigilance by treating physicians. CONCLUSIONS: Individualisation, preservation of beta-cell mass and function and cardiorenal protection are the new challenges in LADA therapy.

RESUMO

Emerging data are linking coronavirus disease 2019 (COVID-19) with an increased risk of developing new-onset diabetes. The gut has been so far out of the frame of the discussion on the pathophysiology of COVID-19-induced diabetes, with the pancreas, liver, and adipose tissue being under the spotlight of medical research. Sodium-glucose co-transporters (SGLT) 1 represent important regulators of glucose absorption, expressed in the small intestine where they mediate almost all sodium-dependent glucose uptake. Similar to what happens in diabetes and other viral infections, SGLT1 upregulation could result in increased intestinal glucose absorption and subsequently promote the development of hyperglycaemia in COVID-19. Considering the above, the question whether dual SGLT (1 and 2) inhibition could contribute to improved outcomes in such cases sounds challenging, deserving further evaluation. Future studies need to clarify whether putative benefits of dual SGLT inhibition in COVID-19 outweigh potential risks, particularly with respect to drug-induced euglycaemic diabetic ketoacidosis, gastrointestinal side effects, and compromised host response to pathogens.

RESUMO

A hypocaloric diet, based on Orthodox fasting (OF) was followed by 29 overweight adults. A low-calorie, 16/8, time restricted eating (TRE) pattern was followed by 16 age- and weight-matched participants. Anthropometric, lipid, glycaemic and inflammation markers were assessed at baseline, at the end of the intervention (7 weeks from baseline) and 6 weeks after the cessation of diets (13 weeks from baseline). There was a trend of weight loss in both groups, which was evident at week 7 (TRE: -2.1 ± 1.0; OF: -2.0 ± 0.5 kg, p < 0.001 from baseline) and remained significant at week 13 (TRE: -2.9 ± 0.7; OF: -2.6 ± 0.3 kg, p < 0.001 from baseline). In the OF group, lipid concentrations declined at week 7 compared with baseline, increasing at week 13 compared with week 7. Our findings suggest that OF promotes a decrease in lipid concentrations, which however, is not evident 6 weeks after its end.

RESUMO

For seven weeks, 37 overweight adults followed a hypocaloric diet based on Orthodox Fasting (OF). A hypocaloric, time restricted eating (TRE) plan (eating between 08:00 to 16:00 h, water fasting from 16:00 to 08:00 h) was followed by 23 Body Mass Index (BMI)-matched participants. Anthropometric, glycaemic and inflammation markers and serum lipids were assessed before and after the diets. Both OF and TRE groups demonstrated reductions in BMI (28.54 ± 5.45 vs 27.20 ± 5.10 kg/m2, p < 0.001 and 26.40 ± 4.11 vs 25.81 ± 3.78 kg/m2 p = 0.001, respectively). Following the intervention, the OF group presented lower concentrations of total and low-density lipoprotein-cholesterol, compared with the pre-fasting values (178.40 ± 34.14 vs 197.17 ± 34.30 mg/dl, p < 0.001 and 105.89 ± 28.08 vs 122.37 ± 29.70 mg/dl, p < 0.001, respectively). Neither group manifested significant differences in glycaemic and inflammatory parameters. Our findings suggest that OF has superior lipid lowering effects than the TRE pattern.

RESUMO

BACKGROUND: Patients' views on the relative importance of treatment outcomes and medication attributes for type 2 diabetes may differ from clinicians' perceptions. OBJECTIVE: To assess which treatment outcomes and medication attributes are considered important by patients and clinicians for therapeutic decisions in type 2 diabetes. DESIGN: Exploratory, sequential, mixed-methods design comprising a qualitative (focus groups) and a quantitative (survey) phase. PARTICIPANTS: Patients in the focus groups (n = 33) and the survey study (n = 656) were recruited from 4 and 9 diabetes clinics across Greece, respectively. Clinicians in the survey study (n = 363) were identified from Greek registries for healthcare professionals. MEASUREMENTS: We conducted 6 focus groups to obtain patients' views regarding the impact of type 2 diabetes on their lives. Identified themes informed the development of a survey, which aimed to assess which outcomes and medication attributes are considered most important by patients and clinicians. We calculated odds ratios to compare patients' and clinicians' responses. RESULTS: The focus groups identified 6 main themes and 15 subthemes. In the survey study, patients were more likely than clinicians to rate prevention of amputation (odds ratio, 9.32; 95% CI, 6.51 to 13.35), diabetic eye disease (6.16; 4.63 to 8.21), sexual dysfunction, and stroke as important, while clinicians were more likely than patients to choose risk for hypoglycemia, and reduction of all-cause mortality, HbA1c, and body weight. Compared with clinicians, patients were less concerned about drug cost (0.16; 0.11 to 0.23), but more concerned about route of administration and need for less frequent glucose self-monitoring. CONCLUSIONS: Patients and clinicians differ in the perception of the relative importance of treatment outcomes and drug characteristics. Individual patient preferences should be explored and implemented in the therapeutic decision-making for type 2 diabetes.

RESUMO

BACKGROUND: Although primary hyperparathyroidism has been associated with insulin resistance, potential optimal effects of parathyroidectomy (PTX) on glucose homeostasis remain controversial. Accordingly, the impact of PTX on glucose-stimulated incretin (glucagon-like peptide 1 [GLP-1] and gastric inhibitory peptide) secretion has not been evaluated. The aim of this pilot study was to compare glucose-stimulated incretin secretion (GSIS) in patients with asymptomatic primary hyperparathyroidism with normal glucose homeostasis, before and after PTX. METHODS: Fourteen patients were included in the study. Fasting calcium, parathyroid hormone, glucose, insulin, GLP-1, and gastric inhibitory peptide were measured pre- and post-operatively. Homeostasis Model Assessment 2, QUICKI, and Matsuda indexes were used as markers of insulin sensitivity and resistance before and after PTX. Preoperatively, a 75 g oral glucose tolerance test (OGTT) was performed to evaluate the response of glucose, insulin, and GSIS. OGTT measurements were repeated 6 ± 2 wk post-PTX. RESULTS: Patients had a mean age of 52.93 ± 9.96 y, and female-to-male ratio was 12:2. Pre- and post-operatively, a positive correlation between parathyroid hormone and Homeostasis Model Assessment 2 for ß-cell function was evident (r = 0.74, P = 0.002 and r = 0.55, P = 0.04, respectively). After PTX, a significant increase in GSIS for GLP-1 during OGTT was observed (in 60 min: 63.06 ± 44.78 versus 102.64 ± 40.19 pg/mL, P = 0.02; and in 120 min: 71.20 ± 35.90 versus 102.49 ± 40.02 pg/mL, P = 0.03). CONCLUSIONS: The increase of GLP-1 response following oral glucose load after PTX may reflect an initial recovery phase of glucose homeostasis. Long-term studies are required to elucidate the physiological interplay between the normalization of calciotropic axis and the rising GLP-1 concentrations post-PTX.

RESUMO

BACKGROUND: Strict glycaemic control early in the treatment process has been shown to reduce the occurrence of micro- and macro- vascular complications of diabetes in the long-term. Thus, treatment guidelines advise early intensification of treatment to achieve glycaemic control goals. However, evidence in Greece suggests that, despite guideline recommendations, glycaemic control among patients with T2DM remains challenging. This study presents the demographic and clinical characteristics of patients with T2DM in Greece using data from an electronic registry designed specifically for this treatment category and investigates the factors that are independently associated with glycaemic control. METHODS: This is a multi-center, observational, cross-sectional study to investigate epidemiological and clinical factors affecting glycaemic control among patients with T2DM in Greece. Data was collected via a web-based disease registry, the Diabetes Registry, which operated from January 1st to December 31st, 2017. Five large specialized diabetes centers operating in Greek hospitals participated in the study. RESULTS: Data for 1141 patients were retrieved (aged 63.02 ± 12.65 years, 56.9% male). Glycaemic control (Hb1Ac < 7%) was not achieved in 57.1% of patients. Factors independently associated with poor glycaemic control were: family history of diabetes [OR: 1.53, 95% CI: 1.06-2.23], BMI score between 25 to 30 [OR: 2.08, 95% CI: 1.05-4.13] or over 30 [OR: 2.12, 95% CI 1.12-4.07], elevated LDL levels [OR: 1.53, 95% 1.06-2.21] and low HDL levels [OR: 2.12, 95% CI: 1.44-3.12]. Lastly, use of injectable antidiabetic agents (in monotherapy or in combination) was less likely to be associated with poor glycaemic control versus treatment with combination of oral and injectable agents [OR: 0.50, 95% CI: 0.24-1.01]. This association was found to be marginally statistically significant. CONCLUSION: Inadequate lipid control, family history of diabetes and presence of obesity (ΒΜΙ ≥ 30 kg/m2) were associated with poor glycaemic control among study sample, whereas use of injectable antidiabetic agents was less likely to be associated with poor glycaemic control. These findings indicate how complex optimal glycaemic control is, highlighting the need for tailored interventions in high-risk subpopulations with T2DM.

RESUMO

WHAT IS KNOWN AND OBJECTIVE: In the outpatient setting, sodium-glucose co-transporter 2 inhibitors (SGLT2i) are recognized as effective agents to optimize glycaemia and also developing robust evidence for cardiovascular (CV) and renal protection in people with type 2 diabetes, particularly those at higher risk. However, data on the safety and efficacy of these drugs in hospitalized patients remain limited. The purpose of this review is to discuss the balance between risks and benefits of SGLT2i use in the inpatient setting. METHODS: PubMed, Embase and Google Scholar databases were searched to identify relevant published work. Available evidence on the mechanisms of action and the safety profile of SGLT2i in the context of their use in hospitalized individuals are summarized and discussed in this narrative review. RESULTS AND DISCUSSION: The rationale behind the use of these agents in the inpatient setting is based on the low risk of hypoglycaemia, the practical dosing scheme and the potential to decrease subsequent heart failure admission rates. In addition, data from animal studies indicate the ability of SGLT2i to ameliorate oxidative stress, suppress sympathetic activity, enhance autophagy and promote cardiac remodelling, when administered in the acute phase of CV episodes. On the other hand, these drugs have been linked to specific adverse events related to their mechanism of action, including an increased risk of euglycaemic diabetic ketoacidosis and volume depletion, which raises concerns over their usefulness in inpatients, particularly individuals with multimorbidities. WHAT IS NEW AND CONCLUSION: Potential benefits deriving from the use of SGLT2i in the inpatient setting cannot mitigate possible risks, at least until robust evidence on their efficacy in hospitalized individuals become available. The concept of administering these agents in the acute phase of CV episodes, in people with or without diabetes, requires further evaluation in appropriately designed clinical studies.

RESUMO

AIMS: To assess the effect of liraglutide on 24-hour ambulatory blood pressure and heart rate in patients with hypertension (pre- and stage 1 hypertension) and inadequately controlled Type 2 diabetes (glycated haemoglobin 7%-10% [53-86 mmol/mol]). MATERIALS AND METHODS: Eligible patients for this investigator-initiated, parallel-group, randomized, double-blind trial were on stable background antihyperglycaemic therapy excluding insulin, glucagon-like peptide-1 receptor agonists and dipeptidyl-peptidase-4 inhibitors. Participants were centrally randomized in a 1:1 ratio to daily liraglutide 0.6 mg, titrated to 1.2 mg after the first week, or placebo for 5 weeks. The primary outcome was change in 24-hour ambulatory systolic blood pressure (SBP), and secondary outcomes included change in ambulatory diastolic blood pressure (DBP) and heart rate. We also assessed renal sodium handling. RESULTS: Of 87 patients assessed for eligibility, 62 (66.1% men) with a mean age of 60.2 years were randomized to liraglutide (n = 31) or placebo (n = 31). All participants received background therapy with metformin, whilst 35.5% were treated concomitantly with sulphonylureas and 14.5% with pioglitazone. Compared with placebo, liraglutide reduced 24-hour SBP by -5.73 mm Hg (95% confidence interval [CI] -9.81 to -1.65) and had a neutral effect on 24-hour DBP (mean difference - 1.42 mm Hg; 95% CI -4.25 to 1.40), whilst increasing 24-hour heart rate by 6.16 beats/min (95% CI 3.25 to 9.07). Findings were consistent for daytime and night-time measurements. Liraglutide did not increase urine sodium excretion. CONCLUSION: Based on 24-hour ambulatory measurements, short-term treatment with liraglutide had a favourable effect on SBP whilst increasing heart rate.

RESUMO

PURPOSE: The primary aim of this study was to investigate the effect of gestational diabetes mellitus (GDM) on the quality of life (QoL) of pregnant women during the third trimester of pregnancy. The secondary aim was to compare the QoL of pregnant women with GDM according to their therapeutic approach. This is the first study of this kind conducted in Greece. METHODS: A case-control study with 62 pregnant women (31 with GDM and 31 with uncomplicated pregnancy), during the third trimester of pregnancy. QoL and Health Related QoL were studied with the use of three questionnaires (EQ-5D-5L, WHOQOL-BREF and ADDQoL). RESULTS: A decrease in the QoL was found in pregnant women with GDM compared with pregnant women with uncomplicated pregnancy (p < 0.05) regarding both social life and health scales. On the contrary, there was no difference in the QoL between pregnant women with GDM who followed different treatment approaches (diet or insulin). CONCLUSIONS: The diagnosis of GDM is associated with a reduction in the QoL of pregnant women during the third trimester of pregnancy, while the type of treatment does not seem to further affect it. More studies should be conducted so that the modifiers of this association can be clarified.

RESUMO

An increase in fracture risk has been reported in patients with type 2 diabetes mellitus (T2DM) treated with canagliflozin, possibly mediated by effects induced by all members of the sodium-glucose co-transporter-2 (SGLT2) inhibitor class. It is unclear whether initiation of dapagliflozin is followed by an increase in the risk of fracture; therefore, we performed a population-based, open cohort study (from January 2013 to January 2016) using The Health Improvement Network (THIN). A total of 22 618 people with T2DM (4548 exposed to dapagliflozin and 18 070 receiving standard antidiabetic treatment, matched for age, sex, body mass index and diabetes duration) with no history of fractures at baseline were included. The primary outcome was the occurrence of any fragility fracture (hip, spine, wrist) during the observation period. Risk of any fracture served as a secondary outcome. Adjusted hazard rate ratios (HRs) with 95% confidence intervals (CIs) were calculated using Cox regression. A total of 289 fractures (132 fragility fractures) were recorded. No difference in the risk of fragility fracture was detected between participants prescribed dapagliflozin and matched control participants (crude HR 0.90, 95% CI 0.59-1.39, P = .645; adjusted HR 0.87, 95% CI 0.56-1.35, P = .531). Similarly, no difference in the risk of any fracture was detected (adjusted HR 0.89, 95% CI 0.66-1.20; P = .427). Sensitivity analyses limited to the subset of the population at high risk of fracture produced similar results; thus, there was no evidence to suggest an increase in the risk of treatment-emergent fractures in patients with T2DM who initiated treatment with dapagliflozin.
