Abstract

With more renal allograft recipients becoming pregnant, it is important to refine existing pre-pregnancy assessment criteria and to identify other factors influencing perinatal outcome. We analyzed gestational renal response and acute or chronic hypertension in relation to perinatal outcome for 22 pregnancies that continued beyond 28 weeks' gestation in 17 allograft recipients (mean age 27 years, range 20-40) transplanted between 1967-1987. Before pregnancy, all had plasma creatinine of 1.62 mg/dL or less and 24-hour creatinine clearance of 39 mL/minute or greater. Six pregnancies were to four women on antihypertensive therapy. Mean arterial pressure (MAP), antihypertensive therapy, plasma creatinine, and 24-hour creatinine clearance were recorded before and during pregnancy. Perinatal outcome was adverse in ten pregnancies: five stillbirths, four growth-retarded infants, and one neonatal death, whereas 12 pregnancies had satisfactory perinatal outcome. Early-pregnancy increments and late-pregnancy decrements in renal function were identical in both groups. Mean arterial pressure was significantly higher at 16-28 weeks in women having adverse outcomes. Hypertension (MAP above 107 mmHg) occurred in 16 pregnancies (73%); it appeared before 28 weeks in seven and was invariably associated with adverse outcome. Hypertension appeared after 28 weeks in nine women and was associated with adverse outcome in only two cases. Five of six pregnancies in women who were on pre-pregnancy antihypertensive therapy ended in adverse outcome. It can be concluded that renal function was identical in pregnancies having adverse or satisfactory perinatal outcome, whereas hypertension before or during early pregnancy, albeit apparently satisfactorily controlled, appeared to be associated with adverse perinatal outcome.
