Fructosamine assay determines glycaemic control in diabetic patients by measuring glycosylated plasma protein. This study was done to assess the value of fructosamine as an alternative test to HbA1c as a measure of glycaemia. Sixty patients (both insulin dependent diabetes mellitus and non insulin dependent diabetes mellitus) were selected from the diabetic clinic and fasting blood samples were...
The serum fructosamine concentrations measured in 64 diabetic patients correlated (r = 0.73) with glycated hemoglobins (HbA1c). However, 23 percent of the diabetic patients had normal fructosamine and abnormal HbA1c levels. In order to determine whether or not the discrepant values were the result of recent glycemic regulation by the diabetic patient, fructosamine levels of patients suffering f...
OBJECTIVE Slowing the diabetes epidemic in Africa requires improved detection of prediabetes. A1C, a form of glycated hemoglobin A, is recommended for diagnosing prediabetes. The glycated proteins, fructosamine and glycated albumin (GA), are hemoglobin-independent alternatives to A1C, but their efficacy in Africans is unknown. Our goals were to determine the ability of A1C, fructosamine, and GA...
The influence of obesity on plasma fructosamine concentration was studied in 68 diabetic and 1335 nondiabetic subjects from a Chinese community. Obese nondiabetic men (body mass index > 25 kg/m2) had lower fructosamine concentrations than nonobese nondiabetic men (body mass index < or = 25 kg/m2); the pattern was similar for diabetic women. Stepwise multiple-regression analysis showed that, apa...
We determined fructosamine concentrations with the CentrifiChem 600 centrifugal analyzer and the Hitachi 737 discrete analyzer. Reference intervals agreed with the most recently published results, and values in fasting patients were significantly correlated with glycated hemoglobin, plasma glucose, albumin, beta- and gamma-globulins, IgG, IgA, IgM, and total protein. Partial correlation analysi...
We optimally solubilized the diformazan that forms during the fructosamine reaction with a nonionic detergent; we then automated the assay. After optimal solubilization of diformazan, we found that serum urate contributed significantly to the color formation in fructosamine reaction. When the error introduced by urate was corrected mathematically by use of an experimental determined factor, the...
OBJECTIVE Assays for serum total glycated proteins (fructosamine) and the more specific glycated albumin may be useful indicators of hyperglycemia in dialysis patients, either as substitutes or adjuncts to standard markers such as hemoglobin A1c, as they are not affected by erythrocyte turnover. However, their relationship with long-term outcomes in dialysis patients is not well described. RE...
Serum fructosamine was measured in 275 blood donors, in 559 subjects with a normal pregnancy, in 32 gestational diabetics being treated with insulin and 69 being treated by diet only, and in 53 pregnant subjects with established diabetes. In none of the pregnant subgroups did the mean fructosamine concentration exceed that of the donor group. The concentration in normal pregnant subjects showed...
Fructosamine 3-kinase, which phosphorylates low-molecular-mass and protein-bound fructosamines on the third carbon of their deoxyfructose moiety, is quite active in erythrocytes, and was proposed to initiate a process removing fructosamine residues from proteins. In the present study, we show that incubation of human erythrocytes with 200 mM glucose not only caused the progressive formation of ...
Diabetes mellitus is a common endocrinopathy of cats that is characterized by persistent fasting hyperglycemia. However, stress induces substantial hyperglycemia in cats that poses a challenge to the veterinarian who may wrongly interpret the high serum concentration of blood glucose as evidence of diabetes mellitus. Fructosamine is a glycated serum protein that serves as an index of glycemic c...
