Abstract
Emphysematous pyelonephritis (EPN) is a necrotizing bacterial infection characterized by gas retention and a poor prognosis. We present the case of a 75-year-old man who was diagnosed early with EPN and received multidisciplinary treatment. He had poorly controlled type 2 diabetes mellitus (DM) and chronic kidney disease (CKD), and was treated with oral hypoglycemic drugs, including a sodium-glucose co-transporter-2 inhibitor. He experienced the onset of back pain in the midsection of his back, tenderness in the costovertebral angle, and a high fever (> 39 °C), accompanied by tachycardia, hypotension, and tachypnea. The patient was diagnosed with pyelonephritis and septic shock. Immediate measures encompassing empirical antibiotic therapy, administration of noradrenaline, blood glucose regulation, and urethral catheterization were implemented. However, due to the persistent fever (> 38 °C) and lack of improvement in his condition, abdominal computed tomography (CT) was repeated on the fourth day. This revealed the presence of gas around the right kidney parenchyma, leading to a diagnosis of EPN that had evolved from acute pyelonephritis. Subsequently, percutaneous drainage of the right kidney parenchyma was performed. Subsequently, multidisciplinary treatment was continued, and his condition gradually improved. Clinicians should evaluate abdominal CT when acute pyelonephritis does not improve within a few days of antibiotic therapy. Disease progression from acute pyelonephritis to EPN should be considered in patients with DM and CKD.

Abstract
Sodium-glucose cotransporter 2 (SGLT2) inhibitors were initially developed for their glucose-lowering effects and have shown a modest glycaemic benefit in people with type 2 diabetes mellitus (T2DM). In the past decade, a series of large, robust clinical trials of these therapies have demonstrated striking beneficial effects for various care goals, transforming the chronic disease therapeutic landscape. Cardiovascular safety studies in people with T2DM demonstrated that SGLT2 inhibitors reduce cardiovascular death and hospitalization for heart failure. Subsequent trials in participants with heart failure with reduced or preserved left ventricular ejection fraction demonstrated that SGLT2 inhibitors have beneficial effects on heart failure outcomes. In dedicated kidney outcome studies, SGLT2 inhibitors reduced the incidence of kidney failure among participants with or without diabetes. Post hoc analyses have suggested a range of other benefits of these drugs in conditions as diverse as metabolic dysfunction-associated steatotic liver disease, kidney stone prevention and anaemia. SGLT2 inhibitors have a generally favourable adverse effect profile, although patient selection and medication counselling remain important. Concerted efforts are needed to better integrate these agents into routine care and support long-term medication adherence to close the gap between clinical trial outcomes and those achieved in the real world.

Abstract
Sodium-glucose cotransporter-2 inhibitors (SGLT2is) have been shown to reduce adverse cardiovascular events in patients with type 2 diabetes mellitus, all-cause mortality, and heart failure hospitalization in patients with heart failure, as well as adverse renal outcomes. However, concerns regarding the heightened risk of genitourinary (GU) infections, particularly urinary tract infections, remain a significant barrier to their wider adoption. Addressing these misconceptions using existing evidence is needed to ensure proper risk-benefit assessment and optimal utilization of this efficacious therapy. This review aims to provide a balanced perspective on the evidence-based cardiovascular and renal benefits of SGLT2is and the associated risk of GU infections. We also summarize and propose clinical practice considerations for SGLT2i-associated GU infections focusing on patients with cardiovascular disease.

Abstract
Traditional approaches to prevention of the complications of type 2 diabetes (T2D) and obesity have focused on reduction of blood glucose and body weight. The development of new classes of medications, together with evidence from dietary weight loss and bariatric surgery trials, provides new options for prevention of heart failure, chronic kidney disease, myocardial infarction, stroke, metabolic liver disease, cancer, T2D, and neurodegenerative disorders. Here I review evidence for use of lifestyle modification, SGLT-2 inhibitors, GLP-1 receptor agonists, selective mineralocorticoid receptor antagonists, and bariatric surgery, for prevention of cardiorenal and metabolic complications in people with T2D or obesity, highlighting the contributions of weight loss, as well as weight loss-independent mechanisms of action. Collectively, the evidence supports a tailored approach to selection of therapeutic interventions for T2D and obesity based on the likelihood of developing specific complications, rather than a stepwise approach focused exclusively on glycemic or weight control.

The impact of sodium-glucose co-transporter-2 inhibitors on dementia and cardiovascular events in diabetic patients with atrial fibrillation. Diabetes Metab Res Rev 2024; 40:e3775. [PMID: 38340046 DOI: 10.1002/dmrr.3775] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Revised: 11/28/2023] [Accepted: 12/12/2023] [Indexed: 02/12/2024]
Abstract
AIMS The effectiveness of sodium-glucose co-transporter-2 inhibitors (SGLT2i) on incident dementia in patients with diabetes and atrial fibrillation (AF) remains unknown. This study aimed to investigate the association between SGLT2i and the risk of incident dementia in diabetic patients with AF, and to explore the interactions with oral anticoagulants or dipeptidyl peptidase-4 inhibitors (DPP4i). MATERIALS AND METHODS We conducted a cohort study using Taiwan's National Health Insurance Research Database. Patients with diabetes and AFwithout a prior history of established cardiovascular diseases, were identified. Using propensity score matching, 810 patients receiving SGLT2i were matched with 1620 patients not receiving SGLT2i. The primary outcome was incident dementia, and secondary outcomes included composite cardiovascular events and mortality. RESULTS After up to 5 years of follow-up, SGLT2i use was associated with a significantly lower risk of incident dementia (hazard: 0.71, 95% confidence interval: 0.51-0.98), particularly vascular dementia (HR: 0.44, 95% CI: 0.24-0.82). SGLT2i was related to reduced risks of AF-related hospitalisation (HR: 0.72, 95% CI: 0.56-0.93), stroke (HR: 0.75, 95% CI: 0.60-0.94), and all-cause death (HR: 0.33, 95% CI: 0.24-0.44). The protective effects were consistent irrespective of the concurrent use of non-vitamin K antagonist oral anticoagulants (NOACs) or DPP4i. CONCLUSIONS In diabetic patients with AF, SGLT2i was associated with reduced risks of incident dementia, AF-related hospitalisation, stroke, and all-cause death. The protective effects were independent of either concurrent use of NOACs or DPP4i.
