This study compares pregnancy outcomes in systemic lupus erythematosus (SLE) patients post renal transplant with recipients with other primary diagnoses, utilizing data from the National Transplantation Pregnancy Registry, Philadelphia, PA. Recipients were referred from transplant centers nationwide. A retrospective analysis was performed using data from questionnaires, hospital records and telephone interviews. Outcomes of pregnancies post renal transplant secondary to lupus nephritis (SLE: n = 38; 60 pregnancies) were compared with the pregnancy outcomes of renal recipients with other diagnoses (non-SLE: n = 247; 374 pregnancies). Drug-treated hypertension during pregnancy was less common in the SLE group than in the non-SLE group (45.0% vs. 62.5%, p = 0.015). There were fewer cesarean sections in the SLE group (30.2 vs. 53.2%, p = 0.008). There was no primary or gestational diabetes in the SLE group. There were no other statistical differences in maternal conditions or pregnancy outcomes between the SLE and non-SLE groups, or in the incidence of post pregnancy graft loss. Female recipients transplanted for renal failure secondary to lupus nephritis can successfully maintain pregnancy. Outcomes are comparable to renal recipients with other diagnoses. Newborns in both groups were often premature and had low birthweight. Overall childhood health was reported to be good; there were no apparent predominant structural malformations among the children.
