Successful Pregnancy in a Kidney-Pancreas Transplanted Patient on LifeCycle Pharma Tacrolimus (LCPT)-Based Immunosuppression

Patient: Female, 25-year-old Final Diagnosis: Type 1 diabetes mellitus Symptoms: No symptoms Medication:— Clinical Procedure: Immunosuppression Specialty: Metabolic Disorders and Diabetics OBJECTIVE: Unusual clinical course BACKGROUND: There has been, to our knowledge, no reports on LifeCycle Pharma tacrolimus (LCPT) taken during pregnancy after simultaneous pancreas-kidney transplantation (SPK). Here, we report a 25-year-old female SPK recipient who gave birth to a healthy infant in posttransplant month 32. We analyzed the long-term graft function, obstetric/neonatal course, LCPT dosage, tacrolimus (TAC) levels, concomitant medication, and complications. CASE REPORT: Her medical history consisted of type 1 diabetes with chronic nephropathy, arterial hypertension, and atypical haemolytic uremic syndrome with critical deterioration of her general condition requiring clinically indicated early termination of her first pregnancy prior to SPK. SPK was performed according to surgical standards. The immunosuppressive prophylaxis consisted of thymoglobulin, mycophenolate mofetil, standard TAC formulation, and steroids. Due to rapid TAC metabolism, the patient was converted from a standard TAC formulation to LCPT in the first month posttransplant. Her long-term immunosuppression, including the obstetric and peripartal course, consisted of LCPT, prednisolone, and azathioprine. She was normotensive without antihypertensive medication and maintained excellent function of both grafts during the observation period of 48 months post-transplant. All (mostly infectious) complications were reversible, especially temporary polyoma viremia within normal renal function, and 2 episodes of urosepsis. No relapse of her pretransplant episode of atypical haemolytic uremic syndrome occurred posttransplant. Her child is in good health at the age of 12 months without any malformations. CONCLUSIONS: This case suggests that pregnancy after SPK under LCPT is feasible. Further studies are needed to expand the empirical knowledge surrounding tacrolimus.
