Diabetes newly diagnosed during pregnancy: A 4-year study at Groote Schuur Hospital.


As a result of active screening for gestational diabetes of the population attending various antenatal clinics in the Cape Peninsula, 127 patients with a repeatedly diabetic glucose tolerance test (GTT) were discovered; in many the GTT was grossly abnormal. The most useful screening factor was repeated glycosuria. Because they had booked late, 22 patients received virtually no treatment, and 1 patient aborted. Treatment of the remaining 104 patients was achieved principally by regulating diet, but when this failed metformin or glibenclamide therapy was instituted. Insulin was used when diet and oral drugs failed. Diabetic control was considered adequate if fasting blood glucose levels remained below 5,5 mmol/l and if postprandial levels were below 7 mmol/l. Most patients (67) were well controlled on a strict dietary regimen, and there were no perinatal deaths in this group. Glibenclamide and metformin, judging from this small series, appear to be safe for use in gestational diabetics. The overall perinatal mortality in treated patients was 10/1 000 as compared with an effective perinatal mortality of 145/1 000 in the 'untreated' group. Neonatal morbidity was similar to that in other reported series. Hypoglycaemia was seldom a problem and 79% of birth weights were between the 10th and the 90th percentiles.
