Abstract

PH1 is an inborn error of the metabolism in which a functional deficiency of the liver-specific peroxisomal enzyme, AGT, causes hyperoxaluria and hyperglycolic aciduria. Infantile PH1 is the most aggressive form of this disease, leading to early nephrocalcinosis, systemic oxalosis, and end-stage renal failure. Infantile PH1 is rapidly fatal in children unless timely liver-kidney transplantation is performed to correct both the hepatic enzyme defect and the renal end-organ damage. The surgical procedure can be further complicated in infants and young children, who are at higher risk for vascular anomalies, such as IVC thrombosis. Although recently a limited number of children with IVC thrombosis have underwent successful kidney transplantation, successful multi-organ transplantation in a child with complete IVC thrombosis is quite rare. We report here the interesting and technically difficult case of a three-yr-old girl with a complete thrombosis of the IVC, who was the recipient of combined split liver and kidney transplantation for infantile PH1. Although initial delayed renal graft function with mild-to-moderate acute rejection was observed, the patient rapidly regained renal function after steroid boluses, and was soon hemodialysis-independent, with good diuresis. Serum and plasma oxalate levels progressively decreased; although, to date they are still above normal. Hepatic and renal function indices were at, or approaching, normal values when the patient was discharged 15-wk post-transplant, and the patient continues to do well, with close and frequent follow-up. This is the first report of a successful double-organ transplant in a pediatric patient presenting with infantile PH1 complicated by complete IVC thrombosis.
