title: The influence of antecedent renal disease on pregnancy.
abstract: The influence of antecedent renal disease on pregnancy was studied retrospectively in 72 women with various renal diseases that had been proved by biopsy. Among 105 pregnancies studied, normal deliveries were observed in 74 (71%), abnormal deliveries with live infants in 14 (13%), fetal or neonatal deaths in 11 (10%), and spontaneous abortions in six (6%). The incidence of normal delivery, as well as that of live births, was the highest in the cases of membranous glomerulonephritis, but there was no obvious difference in the incidence among IgA nephropathy and non-IgA proliferative glomerulonephritis. Cases in which there were tubulointerstitial changes of the cortical area or arteriosclerosis in biopsy specimens and cases that included hypertension (greater than 140/90 mm Hg) or decreased renal function (glomerular filtration rate, less than 70 ml/min) were clearly associated with an unfavorable outcome in delivery. It was concluded that assessment of the advisability of pregnancy in nephritic women should be made on the basis of a combination of the clinical and histologic parameters.
