Glycated haemoglobin (HbA(1c)) is considered the gold standard for assessing diabetes compensation and treatment. In addition, fortuitous detection of haemoglobin variants during HbA1c measurement is not rare. Recently, two publications reported different conclusions on accuracy of HbA(1c) value using capillary electrophoresis method in presence of haemoglobin J-Baltimore (HbJ).
Here we describ...

Using microscopic immunodiffusion assays and microdensitometric analysis of pericellular immunoprecipitate, the percentage of nucleated erythrocytes containing fetal hemoglobin (FNRBC) and the mean picograms of fetal or adult hemoglobin per nucleated erythrocyte (picograms HbF/NRBC, picograms HbA/NRBC) were assayed in 14-d-old colonies (bursts) derived from peripheral blood erythroid progenitor...

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...

The apparent proportion of column-chromatographically measured glycosylated hemoglobin in erythrocytes from an individual with hemoglobins A, S, and G was only 2.3% because the slow glycosylated variant hemoglobins were retarded in the column. In contrast, the value for glycosylated hemoglobin was 7.8% by a new cellulose acetate electrophoretic method that includes use of dextran sulfate buffer...

BACKGROUND The diabetes prevalence increases at an alarming rate around the world and understanding disparities in occurrence, care management, and health outcomes may be a starting point towards achieving more effective strategies to prevent and manage it. The aims of this study are to compare immigrants and Italians in terms of the differences in diabetes prevalence and to evaluate inequaliti...

Hemoglobin is a porphyrin containing protein with an a2b2 tetrameric structure and like other porphyrin compounds shows spectral behavior of species specific characteristics. Researchers tend to relate bands in the hemoglobin spectra to certain structural and/or functional features. Given the fact that hemoglobin is the main oxygen carrier in animals functioning through the Oxy«Deoxy equilibriu...

Aims The aim of this study was to investigate whether subjects included in the diabetes register solely because their HbA1c was over the diagnostic threshold received a diagnosis of diabetes from their general practitioner (GP). Methods The study included all registered cases in 2009-2010 aged 18 or over that were identified only by the laboratory database because they had one or more HbA1c o...

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 6.7 to 22.2% and the results were normally distributed (mean +/- SD 13.2 +/- 2.8%). The normal range in non-diabetics using this method is 4.9 to 8.0%. Results from children who had had diabe...
