We report the first successful use of hepatocyte transplantation as a bridge to subsequent auxiliary partial orthotopic liver transplantation (APOLT) in a child antenatally diagnosed with severe ornithine transcarbamylase (OTC) deficiency. A total of 1.74 x 10(9) fresh and cryopreserved hepatocytes were administered intraportally into the liver over a period of 6 months. Immunosuppression was with tacrolimus and prednisolone. A sustained decrease in ammonia levels and a gradual increase in serum urea were observed except during episodes of sepsis in the first 6 months of life. The patient was able to tolerate a normal protein intake and presented a normal growth and neurological development. APOLT was successfully performed at 7 months of age. We conclude that hepatocyte transplantation can be used in conjunction with APOLT as an effective treatment for severe OTC-deficient patients, improving neurodevelopmental outcomes.
