Comparative Study of Maternal and Perinatal Outcomes among Patients with Pregestational Type I and Type II Diabetes |

Purpose: to evaluate the evolution of gestation, metabolic control and perinatal outcome of pregestational diabetic patients and to perform a comparative study of the results of patients with insulin-dependent diabetes (type I) and non-insulin-dependent diabetes (type II). Methods: retrospective analysis of 57 pregestational diabetic woman charts who began a prenatal follow-up in the Service of Maternofetal Medicine of the Maternidade-Escola Assis Chateaubriand of the Universidade Federal do Ceará, in the period from January 1995 to December 1998. The 57 pregnant women included in the study were divided into groups: the first, composed of 28 patients with insulin-dependent diabetes (type I), and the second with 29 pregnant women with non-insulin-dependent diabetes (type II), controlled with diet or with oral hypoglycemics before pregnancy. Results: there was no statistically significant difference between the two groups in relation to the need of hospitalization for glycemia control (39.2% x 27.5%) and maternal complications, such as: chronic arterial hypertension (14.2% x 27.5%), pregnancy-induced hypertension (14.2% x 17.2%), premature rupture of membranes (3.5% x 10.3%), urinary tract infection (10.7% x 6.8%), and preterm labor (3.5% x 6.8%). However, episodes of maternal hypoglycemia were more frequent among insulin-dependent patients (35.7% x 3.4%). The perinatal results were similar. We observed a great number of congenital anomalies and increased perinatal morbidity and mortality. Conclusion: there was no difference in the incidence of obstetric and clinical complications between insulin-dependent and non-insulin-dependent patients, except for maternal hypoglycemia.
