Successful Pregnancy Post-Kidney Transplant: A Case Report

Pregnancy after renal transplantation is now more feasible, with documented rates of successful live births. However, pregnancy after renal transplantation is associated with an increased risk of maternal complications, including preeclampsia, graft dysfunction, hypertension, and diabetes, as well as adverse perinatal outcomes such as preterm birth and intrauterine growth restriction. Effective care requires a multidisciplinary approach. This report discusses a case of a primigravida patient who successfully delivered at term three years after kidney transplantation, with an emphasis on the clinical decision-making process, challenges, and strategies used to achieve the best possible outcome. We present a 27-year-old female, gravida 1 para 0 (G1P0), with a history of end-stage renal disease secondary to glomerulonephritis, who underwent a renal transplant at age 24. She was maintained on tacrolimus, azathioprine, and prednisolone and had stable graft function throughout follow-up. She also had type 2 diabetes diagnosed after transplantation, which was managed with insulin. After spontaneous conception, she was followed in a high-risk antenatal clinic with joint nephrology and obstetrics oversight. Antenatal care included biweekly monitoring of renal function, including serum creatinine, estimated glomerular filtration rate (eGFR), and electrolytes, therapeutic drug monitoring of tacrolimus trough levels, frequent blood pressure assessments, and fetal surveillance using serial ultrasounds and non-stress testing. Preeclampsia prophylaxis with low-dose aspirin (150 mg) was initiated at the initial antenatal visit. Blood pressure was managed with labetalol, and insulin therapy was continued with input from endocrinology. Immunosuppressive drug doses were carefully adjusted to maintain therapeutic levels. Renal function at 20 weeks was within normal range (creatinine: 0.88 mg/dL, eGFR: >80 mL/min/1.73 m²) with no evidence of graft dysfunction or proteinuria. The remainder of the pregnancy was uneventful until 36+6 weeks, when there was a mild but sustained rise in serum creatinine (1.1 mg/dL) and urea, suggesting early renal stress. After consultation with nephrology, labor was induced at 37 weeks. Stress-dose intravenous hydrocortisone was administered, and a vacuum-assisted vaginal delivery was performed. The neonate weighed 3.39 kg and did not require NICU admission. Postpartum, she experienced an atonic postpartum hemorrhage of approximately 800 mL, which was managed with uterotonic agents and close observation. Renal function stabilized within one week. Immunosuppressants were resumed at their pre-pregnancy doses, and insulin therapy was converted to metformin following endocrinology reassessment. This report highlights the importance of individualized and multidisciplinary care in managing pregnancies among kidney transplant patients. Given the high risk of complications, including preeclampsia (up to 30%) and preterm delivery (50-60%), personalized management strategies are essential. Critical elements include maintaining stable graft function before conception, optimizing immunosuppressive therapy, effectively managing diabetes and hypertension, and detecting changes in renal function early to allow timely delivery.
