Screened Glucosuria During Pregnancy: Correlation with Intravenous Glucose Tolerance Test and Serum Lipids

216 pregnant women with morning glucosuria observed twice at regular testing were subjected to intravenous glucose tolerance tests and serum lipid determinations. A Control Series consisted of 44 pregnant women. An additional group of 24 women with special obstetric histories was also studied. K-values less than 1.0, pointing to diabetes mellitus, were observed in 4.4% of pregnant women with glucosuria, in 5.5% of the control group and in 26.1 % of women with special obstetric histories. No positive correlations were found between the K-value and the duration of pregnancy at the time when glucosuria was detected, number of previous pregnancies, weight of newborn, maximal glucose content and 60 min glucose value during IVGTT. The serum lipid values (triglycerides, total and free cholesterol and non-esterified fatty acids) were clearly elevated in all the groups. No correlation was found between the K-value and serum lipid levels. It is concluded that the significance of screened glucosuria, even if recorde...
