Adherence and treatment continuation rates of the glucagon-like peptide-1 receptor agonist (GLP-1RA) semaglutide for both oral (O-SEMA) and subcutaneous injection (SEMA-SC) remain unknown in real-world clinical practice. This retrospective observational study compared the 12 month adherence and treatment discontinuation of O-SEMA and once-weekly SEMA-SC in patients with type 2 diabetes using a real-world claims database. SEMA-SC initiators were 1:1 propensity score-matched to O-SEMA initiators. Non-adherence was defined as <0.8 of the proportion of days covered. SEMA-SC had a significantly higher odds ratio (OR) for non-adherence than O-SEMA (OR: 1.39). The hazard ratio for treatment discontinuation, using O-SEMA as the reference, was 1.45 for SEMA-SC, although the discontinuation rate of O-SEMA was higher during the early stage. O-SEMA initiators showed significantly higher adherence and greater persistence in therapy than SEMA-SC initiators at 12 months, which could lead to earlier initiation of GLP-1RA treatment.

AIMS: This study aimed to investigate the factors associated with the exacerbation of the severity of atherothrombotic brain infarction at discharge in patients with type 2 diabetes using a large-scale claims database. MATERIALS AND METHODS: This retrospective cross-sectional study utilized the Medical Data Vision administrative claims database, a nationwide database in Japan using acute care hospital data, and the Diagnosis Procedure Combination system. Diagnosis Procedure Combination data collected between April 1, 2008, and December 31, 2022, were extracted. Patients with type 2 diabetes were included. Severe atherothrombotic brain infarction was defined as a modified Rankin scale score of ≥3. RESULTS: Severe atherothrombotic brain infarction occurred in 43,916/99,864 (44.0%) patients with type 2 diabetes. The odds ratio for severe atherothrombotic brain infarction increased significantly per 10 year increments in age (odds ratio: 1.69, 95% confidence interval: 1.66-1.71). A body mass index of <25 kg/m2, with a body mass index of ≥25 kg/m2 as reference, also increased the risk for severe atherothrombotic brain infarction (odds ratio: 1.11, 95% confidence interval: 1.08-1.15). The odds ratios in insulin and dipeptidyl peptidase 4 inhibitor use were significantly higher than 1. In particular, statin use (odds ratio: 0.85, 95% confidence interval: 0.83-0.88), fibrate use (odds ratio: 0.68, 95% confidence interval: 0.59-0.78), aspirin use (odds ratio: 0.78, 95% confidence interval: 0.75-0.80), and P2Y12 inhibitor use (odds ratio: 0.88, 95% confidence interval: 0.85-0.91) were associated with a lower odds ratio for severe atherothrombotic brain infarction. CONCLUSIONS: The active management of lipid levels using statins and fibrates may be beneficial in preventing the exacerbation of atherothrombotic brain infarction in type 2 diabetes patients.

BACKGROUND: Anamorelin is the first drug approved for the treatment of cancer cachexia, a debilitating condition characterized by weight loss, anorexia, and muscle mass depletion. Cachexia negatively affects a patient's quality of life, survival, and response to chemotherapy. Studies describing anamorelin use are currently limited to a small number of pancreatic cancer cases. OBJECTIVES: We aimed to examine the incidence and risk factors of adverse metabolic effects on glucose levels in cachexia patients with various carcinomas treated with anamorelin. METHOD: We used real-world data of patients who received anamorelin between August 2021 and July 2022 and were registered in the JMDC claims database. We investigated the impact of metabolic adverse effects on glucose in patients receiving anamorelin with respect to the following factors: sex (male), age (>75 years), types of carcinoma, history of diabetes mellitus (DM), and concomitant use of steroids. RESULTS: The incidence of adverse metabolic effects on glucose was 12.3%, and pancreatic cancer and history of DM were associated with adverse metabolic effects on glucose. The median onset of adverse metabolic effects on glucose was 17 days after anamorelin treatment. CONCLUSIONS: This study highlights the need to monitor and manage hyperglycemia in cachexia patients receiving anamorelin, especially in those with pancreatic cancer and a history of DM.

We aimed to compare the effects of cardiovascular disease risk in Japanese patients with type 2 diabetes on sodium-glucose cotransporter 2 inhibitors (SGLT2Is) or metformin. This retrospective, real-world cohort study was carried out using a claims database and propensity score matching; 58,402 eligible patients (29,201 per group) were included. The outcomes included nonfatal myocardial infarction, angina pectoris, nonfatal stroke, hospitalization for heart failure and composite end-points. The hazard ratio (HR) for the composite end-point was 0.79, which was lower for SGLT2Is than for metformin. For male patients (HR 0.76), patients aged <65 years (HR 0.94), patients aged ≥75 years (HR 0.78) and patients with body mass index ≥25 kg/m2 (HR 0.76), the HRs for the composite end-point were significantly lower in the SGLT2I group than in the metformin group. SGLT2Is might be superior to metformin in reducing the composite risk of cardiovascular disease in patients with type 2 diabetes.
