This study was carried out to determine whether a short-term zinc supplementation contributes to beneficial changes in glycemic control among type 2 diabetic patients. Seventy-six diabetic subjects and 72 normal adults participated in this study. Subjects were divided into supplemented and control groups. Forty-four diabetic patients and 34 normal subjects were supplemented with 50 mg zinc dail...

BACKGROUND The relationship between glycated haemoglobin and the incidence of end-stage renal disease (ESRD) in patients with diabetes remains uncertain, especially in those with decreased glomerular filtration rate (GFR). The aim of this study was to assess the appropriate HbA(1c) level for diabetics for minimizing the incidence of ESRD and all-cause mortality. METHODS A cohort of patients a...

AIMS Using the HbA(1c) level to define diabetes has several advantages and these advantages also apply to define a high-risk group. However, the risk of diabetes increases as HbA(1c) increases and a certain degree of arbitrariness in the cut-off for the high risk group is unavoidable. The aim of this study was to determine the HbA(1c) cut-off for defining a high-risk group that corresponds to t...

OBJECTIVE To compare the abilities and associated hypoglycemia risks of insulin glargine and human NPH insulin added to oral therapy of type 2 diabetes to achieve 7% HbA(1c). RESEARCH DESIGN AND METHODS In a randomized, open-label, parallel, 24-week multicenter trial, 756 overweight men and women with inadequate glycemic control (HbA(1c) >7.5%) on one or two oral agents continued prestudy ora...

OBJECTIVE Diabetes and hypertension often co-occur and share risk factors. Hypertension is known to predict diabetes. However, hyperglycemia also may be independently associated with future development of hypertension. We investigated glycated hemoglobin (HbA(1c)) as a predictor of incident hypertension. RESEARCH DESIGN AND METHODS We conducted a prospective analysis of 9,603 middle-aged part...

OBJECTIVE We studied a systematic program to reeducate our medical house officers on how to manage inpatient hyperglycemia without the use of sliding-scale insulin (SSI). RESEARCH DESIGN AND METHODS Patients admitted to the general medical service with diabetes or a blood glucose >140 mg/dl were included. HbA(1c) was measured in all patients, and therapy was modified if the HbA(1c) was >7.0%....

OBJECTIVE The aim of this study was to determine whether obesity influences relationships between habitual alcohol drinking and hemoglobin A(1C) (HbA(1C)) level. METHODS Japanese men (35-70 years old, n = 24858) were divided into non-, light (<22 g ethanol/day), moderate (≥22 and <44 g ethanol/day), and heavy (≥44 g ethanol/day) drinkers. Relationships of alcohol with HbA(1C) were investigate...

BACKGROUND Monitoring of hemoglobin A(1c) (HbA(1c)) is important in the management of diabetes. The IFCC reference measurement procedure for HbA(1c) is based on the ratio of glycated to nonglycated N-terminal hexapeptides of the beta-chains of hemoglobin after digestion with Glu-C endoproteinase. We developed a modification of the original reference measurement procedure with HPLC-electrospray ...

A subtype of glycohaemoglobin, haemoglobin (Hb) A(1c), in specimens of whole blood was assayed on a new automated analyser that makes use of high-pressure liquid chromatography. The analyser provided precise and reproducible values. The mean of the HbA(1c) values was lower than that with an older instrument. The mean tended to increase with the age of the subjects, who were undergoing routine h...

BACKGROUND Results of intervention studies in patients with type 2 diabetes have led to concerns about the safety of aiming for normal blood glucose concentrations. We assessed survival as a function of HbA(1c) in people with type 2 diabetes. METHODS Two cohorts of patients aged 50 years and older with type 2 diabetes were generated from the UK General Practice Research Database from November...
