Successful pregnancy in a patient with medullary cystic disease and severe renal impairment.
We present a successful pregnancy in a 37-year-old women with severe renal impairment due to medullary cystic disease. She presented five years earlier with hypertension and chronic renal failure with creatinine was 2.1 mg/dl (Ccr 35 ml/min). She had had two successful pregnancies in the past, nine and seven years earlier. Diagnosis of medullary cystic disease (MCD) was made based on typical ultrasound appearance, sodium wasting and acidosis out of the proportion to the degree of renal failure. Over the next 5 years, a slow progression of chronic renal failure was observed with creatinine reaching 5.1 mg/dl (Ccr 15,4 ml/min), shortly before she became pregnant in December 2001. Her hypertension remained well-controlled and serum creatinine decreased at the beginning of the second trimester to 3.7 mg/dl with subsequent increase toward the end of the pregnancy. She required increasing doses of erythropoietin and intravenous iron supplementation to maintain hemoglobin levels. The polyhydramnios developed necessitating five procedures of amnio reduction. She was not treated by dialysis. A boy weighing 1,600 g was delivered by cesarean section in the 35th week of gestation. The mother's creatinine rose to 5.2 mg/dl (Ccr 15 ml/min) post partum and her renal function declined only slightly over the next 20 months. Our report illustrates that successful fetal and maternal outcome can be achieved even in cases of advanced renal failure preceding gestation. It appears that the type of renal disease influences the pregnancy course and outcome and thus should be considered in patient counseling and therapeutic decisions.
