title: Studies in diabetic pregnancy. I. Serum lipids.
abstract: The serum lipid values at different stages of pregnancy in twenty-six pregnany diabetic women attending a special antenatal clinic at the Department of Obstetrics and Gynecology, were compared with the corresponding values in four control series composed of non-diabetic pregnant women. Control series were studied at weeks 10, 22, 34 and after delivery, respectively. Serum triglycerides were higher in the diabetic women at week 10 (p less than 0.01), week 34 (p less than 0.05) and after delivery (p less than 0.05). Furthermore, in the diabetic women, infant birth weights were correlated (r=0.52, p=0.05) with maternal serum triglyceride values at week 31. Women with the highest serum triglyceride values (greater than 250 mg/100 ml) were delivered of infants with a higher birth weight (p less than 0.05) than those women with lower serum triglyceride values (less than 250 mg/100 ml). Intra-uterine deaths (n=4) were not related to maternal serum triglyceride values, but mean blood glucose values (during the whole pregnancy) were higher (p less than 0.001) in mothers with intra-uterine deaths. Elevated plasma free fatty acids (FFA) in the diabetic mother would be a possible cause for elevated serum triglycerides through increased liver triglyceride synthesis, while in the fetus an excess of plasma FFA (passing through the placental barrier) together with normal or elevated plasma insulin would be a likely explanation for increased triglyceride synthesis in adipose tissue and thereby of increased fat depots and body weight.
