With each new tool the insurance industry obtains to evaluate both states of health and states of disease, the temptation exists to use it in as many contexts as possible. The initial understanding in the mid-1960’s that diabetic individuals have different percentages of specific hemoglobins has led to the study and refinement of the hemoglobin Alc (HbAlc), which is being used increasingly by c...

OBJECTIVE Haemoglobin A1c (Hb A1c) is routinely used for monitoring glycemic control in patients with diabetes. Hb A1c seasonal fluctuations can be directly related to different biological, geographical and cultural influences. Our purpose was to evaluate seasonal variation of Hb A1c in a hospital-based adult population over a period of 5 years. MATERIALS AND METHODS We analyzed retrospective...

Concentrations of total glycosylated haemoglobins (Hb A1) were measured in 40 diabetics at diagnosis and at monthly intervals after treatment with chlorpropamide, insulin, or diet alone was begun. The mean Hb A1 concentration at presentation in 16 patients treated with chlorpropamide was significantly higher than that in 12 patients treated with insulin, and the duration of glycaemic symptoms w...

OBJECTIVE Examine clinical indicators to evaluate diabetes care in Mexico. MATERIAL AND METHODS Diabetics (self reported, with therapy) were examined with standardized questionnaires, anthropometry, glucose, lipids and glycohemoglobin. Data were analyzed statistically. RESULTS There were 2 644 patients, 677 cases without access to medical care (73% women), most lived in rural communities an...

Hemoglobin A1c (HbA1c) measurements are important for monitoring glycemic control in patients with diabetes. The positive impact of point-of-care HbA1c measurements on patient management is described in the literature. The general analytical requirements for HbA1c testing are described. The analytical evaluation of a new point-of-care HbA1c analyzer, suitable for a physician's office, against t...

Total glycosylated haemoglobin (HbA1) levels from capillary blood were studied retrospectively during a 1-year period in 148 diabetic children aged between 1 9 and 16 8 years. The clinic range for HbA1 was 67 to 22 2% and the results were normally distributed (mean ± SD 13 2 ± 28 %). The normal range in non-diabetics using this method is 4 9 to 8-0 %. Results from children who had had diabetes ...

BACKGROUND In persons with diabetes, chronic hyperglycemia (assessed by glycosylated hemoglobin level) is related to the development of microvascular disease; however, the relation of glycosylated hemoglobin to macrovascular disease is less clear. PURPOSE To conduct a meta-analysis of observational studies of the association between glycosylated hemoglobin and cardiovascular disease in diabet...

OBJECTIVES To evaluate the effects of GH replacement therapy (GHR) for 3 years on glycated haemoglobin (HbA1c) and on the presence of dysglycaemia at any time during follow-up in Spanish adult patients with growth hormone deficiency (GHD). STUDY DESIGN A retrospective study of 41 patients with GHD was conducted using baseline and long-term data. Changes in HbA1c values during the first 3 year...

OBJECTIVE To study insulin dependent diabetic patients for change in non-proliferative retinopathy and its relation to glycaemic control and to various clinical background data. DESIGN Prospective study with follow up for seven years. SETTING Outpatient departments of university hospitals. MAIN OUTCOME MEASURES Glycated haemoglobin concentration; degree of retinopathy. RESULTS Retinopat...
