[Glycosylated hemoglobin in pregnant women with glycosuria].

Systematic assays of glycosylated haemoglobin were performed to verify that pregnant women with glycosuria and normal fasting blood glucose and glucose tolerance tests had no disturbances in glycoregulation . Glycosylated haemoglobin levels were measured in 25 glycosuric women on the second (n = 11) or third (n = 14) trimester of pregnancy and compared with those of 81 non-glycosuric women of similar weight and gestational age. On the third trimester, glycosylated haemoglobin levels were significantly higher in glycosuric women of normal weight than in controls (5.85% versus 5.08%; p less than 0.01). They were also significantly higher in obese glycosuric women than in controls of the same weight (6.71% versus 5.3%; p less than 0.001) and exceeded normal limits. These results should encourage better detection (by glucose tolerance test) and better supervision of women with "renal" diabetes.
