Abstract:
A 24-year-old female was diagnosed as having membranoproliferative glomerulonephritis type II (or dense deposit disease), 11 years prior to becoming pregnant. The patient's first renal biopsy was performed 5 years after the onset of her renal symptoms. This biopsy was compared to a second renal biopsy taken just before the patient became pregnant. The second renal biopsy only showed a slight progression in the disease process. During the course of pregnancy, neither renal insufficiency nor hypertension were clinically evident. However, both an increase in proteinuria and a transient hypoalbuminemia were observed. The pregnancy, labor and delivery, and postpartum course for both the mother and child were without complications. Cases of membranoproliferative glomerulonephritis type I and pregnancy have been reported. However, to our knowledge, there are few reports documenting the outcome of pregnancy when a patient has membranoproliferative glomerulonephritis type II. We suggest that it is possible for a patient with membranoproliferative glomerulonephritis type II to have an uneventful pregnancy if she has neither hypertension nor renal insufficiency.
