Outcomes from 197 pregnancies in 141 female kidney transplant recipients were analyzed from data collected via questionnaires, hospital records, and phone interviews. All recipients were maintained on cyclosporine (CsA) before and during pregnancy. Of the livebirths, 54% were premature (< 37 wk) and 50% were low-birthweight (LBW) (< 2500 g). The incidence of recipient drug-treated hypertension (HTN) was 56%; preeclampsia, 29%; infections and complications 22%; and rejection during pregnancy and up to 3 mo. post delivery (rej.), 11%. Graft loss within 2 years of delivery occurred in 9% of recipients (GrL < 2). No recipients reported a pregnancy after a postpregnancy graft loss. Mean serum creatinine was reported before, during, and after pregnancy. Mean cyclosporine doses were similar in recipients during and after pregnancy. Data were analyzed by logistic regression using SAS. Outcomes included prematurity, LBW, rej., and GrL < 2. In a case-controlled study comparing a recipient group with graft dysfunction during pregnancy vs. a group with good graft function, there was a trend toward lower mean prepregnancy CsA doses (in mg/kg) in the graft dysfunction group. A decline in recipient graft function during pregnancy is associated with lower newborn birthweights and lower maternal graft survival in cyclosporine treated female kidney recipients. Pregnancy-related infections and complications are associated with rejection and graft loss in this population. Close monitoring of CsA dosing and serum creatinine levels during pregnancy and immediately postpartum is recommended as CsA dosage adjustment may be required.
