Introduction Posttransplantation diabetes mellitus (PTDM) is a common complication among kidney transplant recipients and is associated with a higher risk of cardiovascular events and poorer graft and patient survival. The association of pretransplantation hemoglobin A1c (HbA1c) with PTDM remains unclear. Identifying recipients at greatest risk for PTDM may help guide monitoring and treatment s...

OBJECTIVE This study aimed to analyze the effect of HbA1c variability on the occurrence of diabetic retinopathy in type 1 diabetes patients. PATIENTS AND METHODS 35,891 patients with childhood, adolescent or adult onset of type 1 diabetes from a large multicentre survey, the German/Austrian prospective documentation system (DPV), were analysed. Cox proportional hazard models were used to exam...

Introduction. Whether changes in adherence are associated with changes in HbA1c is assumed but not known. Methods. We conducted a observational study of 2,844 type 2 diabetes patients who initiated metformin as their first antihyperglycemic drug. Using HbA1c measures before, 6-12 months after, and up to 3 years after metformin initiation, we analyzed HbA1c change as a function of initial adhere...

OBJECTIVE: To evaluate glycemic control in type 1 diabetes mellitus patients followed in 1998. PATIENTS AND METHODS: We studied 38 patients [22 males; age = 10.4 -/+ 4.1 years; 12 (31.6%) prepubertal, 26 (68.4%) pubertal], with diabetes duration of 3.7-/+3.4 years and age of diagnosis of 7.2 -/+ 4.7 years. HbA1c was determined using high-performance liquid chromatography (L-9100 Merck Hitachi, ...

OBJECTIVE Recent Veterans Affairs (VA) guidelines recommend that persons with stable type 2 diabetes controlled on oral agents or diet therapy perform self-monitoring of blood glucose (SMBG) twice weekly. We assessed the impact of a modification of these guidelines on hemoglobin A1c (HbA1c) and monitoring cost. STUDY DESIGN Retrospective, noncrossover clinical trial. PATIENTS AND METHODS We...

OBJECTIVES Ion-exchange high-performance liquid chromatography (IE-HPLC) has long been used as a reproducible and versatile analytical tool for HbA1c measurement. In this study, we performed analytical verification and quality assessment of the recently introduced small IE-HPLC Tosoh HLC-723GX HbA1c analyzer, and a comparison of results to immunoassay (IA) and capillary electrophoresis (CE). ...

OBJECTIVE To determine which measures-impaired fasting glucose (IFG), elevated HbA1c, or both-best predict incident diabetes in older adults. RESEARCH DESIGN AND METHODS From the Health, Aging, and Body Composition study, we selected individuals without diabetes, and we defined IFG (100-125 mg/dL) and elevated HbA1c (5.7-6.4%) per American Diabetes Association guidelines. Incident diabetes wa...

BACKGROUND Ipragliflozin is a selective sodium glucose co-transporter 2 (SGLT2) inhibitor that blocks glucose reabsorption in the proximal tubules. SGLT2 inhibitors are expected to be effective in patients with insulin resistance and obesity, but it is important to select treatment according to patient background factors that minimizes the risk of adverse events. There have been a limited numbe...

BACKGROUND HbA1c ≥ 6.5% has been recommended as a diagnostic criterion for the detection of diabetes mellitus (DM) since 2010 because of its convenience, stability and significant correlation with diabetic complications. Nevertheless, the accuracy of HbA1c compared to glucose-based diagnostic criteria varies among subjects of different ethnicity and risk profile. OBJECTIVES This study aimed t...
