[Diabetic retinopathy and nephropathy--complications in pregnancy and labor].

The purpose of this retrospective study was to determine the risk factors for the morbidity of the mothers and their fetus in patients with diabetic retinopathy and/or nephropathy with an open family planning. We compared the course of pregnancies, complications as well as the maternal and neonatal morbidity in 76 patients with diabetic retinopathy or nephropathy (White R F) with 85 patients without severe microangiopathy (White C D). We found a correlation between retinopathy progression and hyperglycaemia during the first trimester (p < 0.05). There was an increase in the deterioration of visual acuity up to blindness due to the progression of this microangiopathy in cases of proliferative retinopathy. There was a significant increase of the mean diastolic blood pressure (mdp) and preeclamptic symptoms occurred in 71% of the cases with severe microangiopathy (p < 0.05). Deterioration of the diabetic nephropathy with excessive proteinuria (> 10 g/d) and unmanageable hypertension or a progression of the retinopathy led to an earlier delivery in 80% of the patients (p < 0.05). A high rate of preterm deliveries (39%) and a frequent occurrence of intrauterine growth retardation's (9%) characterised the fetal outcome. The following examinations for a patient with an open family planning, if diabetes is diagnosed during childhood or the course of the disease is between 10 and 15 years, should be done: Ophthalmological evaluation, control of the renal function, contraceptive advice and an improvement of the metabolic situation. In case of a diabetic nephropathy in combination with hypertonus the patients shoud be warned against pregnancy.(ABSTRACT TRUNCATED AT 250 WORDS)
