[Hepatic and renal transplantation in the treatment of type I hyperoxaluria]

Abstract

Hyperoxaluria type I (HPI) is a metabolic disorder secondary to liver alanine glyoxylate aminotransferase deficiency. Renal failure occurs due to the excessive production and precipitation of oxalate in the kidney. Combined liver-renal transplantation is the correct treatment for this condition when end-stage renal failure occurs as with renal transplantation alone the risk of recurrence of the same pathology in the transplanted kidney would be high. We report the case of a 4 year-old child with HPI suffering from terminal renal failure in whom a hepato-renal transplantation was performed: six months later, creatinine clearance was 62 ml/min/1.73 m2 and liver function tests were normal.
