Prevalence of hypoglycemia among a sample of sulfonylurea-treated patients with Type 2 diabetes mellitus in Argentina: The real-life effectiveness and care patterns of diabetes management (RECAP-DM) study

Aim: Strict blood glucose control in the treatment of diabetes can sometimes lead to hypoglycemia. The main aim of this study was to assess the prevalence of hypoglycemia among patients receiving sulfonylureas alone, or in combination with metforrnin, for the treatment of Type 2 Diabetes Mellitus (T2DM) in Argentina. Methods: This is a real life, multi-center, retrospective, and cross-sectional study based on clinical chart reviews including cross-sectional data, and evaluation of patient questionnaires of Glycemic control T2DM patients (>30 years), treated with sulfonylureas alone or in combination with metforrmin, during a routine clinic visit in 16 medical centers across Argentina. Socio-demographic and clinical parameters were collected from medical records, as well as hypoglycemic events from both the medical records and the patient questionnaires. The glycated hemoglobin (HbA(1c) ) levels were obtained from medical records as well as a blood test. Results: The study included a total of 397 patients with a mean age of 62.5 years, diagnosed for 9.9 years, and 54.2% mate. Mean HbA(lc) levels were 8.1%, (65 mmol/mol) at enrolment, with 36.4% being in control (HbA(1c) < 7%, (53 mmol/mol). Patients with HbA(1c) < 7%, (53 mmol/mol) were significantly older, diagnosed at older age, and had tower triglyceride levels. Almost 50% reported hypoglycemic episodes that were mostly mild, and with women more likely to report them. The large majority (86%) were on combined metformin and sulfonylureas, most commonly Glibenclamide (48.6%). Patients on combined therapy were significantly younger and more likely to have uncontrolled diabetes. Conclusions: This study demonstrated that out of a sample of 397 patients with T2DM treated with sulfonylureas alone or in combination with metformin in Argentina, around 50% of them reported symptoms of hypoglycemia induced by sulfonylureas, and one third of them achieved target HbA(1c) < 7% levels.
