Abstract
Primary Hyperoxaluria (PH) is a metabolic liver disease that results in oxalate overproduction that cannot be metabolized by the liver [1]. PH is caused by mutations in one of three genes that encode enzymes involved in glyoxylate metabolism. As oxalate is primarily excreted in the urine, the kidney is the prime target for oxalate deposition, which leads to end-stage kidney disease [2]. A patient named MN with Nephrocalcinosis (NC) was referred to the Children`s Memorial Health Institute of Warsaw in early childhood. The patient was diagnosed with PH type 1. PH type 1 is caused by mutations in a gene called AGXT that encodes alanine-glyoxylate aminotransferase. This enzyme is found in hepatic peroxisomes. It converts a compound called glyoxylate to the amino acid glycine [3]. In 02.12.1996, at the age of 13 the patient received a first kidney transplant from family member. In 16/09/1998 graftectomy was performed due to rapidly progressive kidney failure, nephrocalcinosis and infections. The patient had to return to hemodialysis after renal allograft loss. Also the patient was diagnosed with chronic HCV genotype 4 infection in 1998. In 08.11.2002, at the age of 19, the patient was qualified for a simultaneous liver and second kidney transplantation due to primary hyperoxaluria. The patient was treated with combination of: Daclizumab, steroid, tacrolimus, mycophenolate mofetil. Since October, 2015 the patient had been treating with combination of ombitasvir, paritaprevir, ribavirin and ritonavir. Hepatitis C Virus (HCV) was successfully eliminated. Patients with kidney failure from primary hyperoxaluria type 1 should not undergo kidney transplantation alone due to the very high risk of recurrence. Combined liver and kidney transplantation is the treatment of choice [4].
