Osteoarticular cells tolerate short-term exposure to nitisinone-implications in alkaptonuria [PDF]

open access: yes, 2016
Alkaptonuria (AKU) is a rare genetic disease resulting in severe, rapidly progressing, early onset multi-joint osteoarthropathy. A potential therapy, nitisinone, is being trialled that reduces the causative agent; homogentisic acid (HGA) and in a murine ...

Simultaneous succinylacetone-nitisinone measurement in tyrosinemia type I patients and evaluation of nitisinone therapeutic range

open access: yes, 2022
Abstract Introduction: In tyrosinemia type I (HT1) accumulation of succinylacetone causes severe hepatic and renal dysfunction and hepatocellular carcinoma, and the only drug used in the treatment is nitisinone (NTBC). While succinylacetone measurement from dried blood spots (DBS) is used in the diagnosis of patients, simultaneous measurements ...

Tyrosinemia type I: an unusual case presentation

open access: yesJournal of Biochemical and Clinical Genetics, 2022
Background: Hereditary tyrosinemia type 1 (HT1) is an autosomal recessive inherited metabolic disorder caused by the fumerylacetoacetate hydrolase enzyme deficiency. It is characterized by liver dysfunction and/ or failure, renal tubular dysfunction.
