Pregnancy in membranous glomerulonephritis--course, treatment and outcome

The effect and outcome of pregnancy in women with preexisting glomerulonephritis is a controversial issue.

We report the clinical course and treatment of a 23-year-old pregnant woman with biopsy-proven membranous glomerulonephritis. When she conceived, the patient had been in stable remission for 1 year. In the 14th week of pregnancy, the patient developed uncontrolled hypertension and nephrotic syndrome. Daily 1 g methylprednisolone intravenous pulses were administered for 3 days, followed by a 4-week course of oral prednisone, 50 mg/day. Clinical improvement and normalization of arterial blood pressure were achieved. Oral prednisone 60 mg was administered on alternate days for another 4 weeks following 3 days of pulse therapy. At the end of treatment (26th gestational week), we observed a decrease of proteinuria (from 10.6-4.8 g/24 h) and rise in serum albumin (from 2.1-2.9 g/100 ml). At this time, blood pressure was 130/85. In the 34th week, a normal healthy male newborn was delivered by cesarean section. One year later she felt well, her blood pressure was 140/90, serum albumin was 3.4 g/100 ml, urine protein was 1.65 g/24 h and renal function was normal. The patient's child was healthy and well developed.

Judicious use of a specific therapy to the underlying renal disease during pregnancy, together with a continuous supervision, can improve outcomes of these particular high-risk conditions.
