UNASSIGNED: The study aims to highlight the different clinical presentations of Hereditary Tyrosinemia type 1 in a cohort of Pakistani children.
UNASSIGNED: Retrospective observational study.
UNASSIGNED: All patients diagnosed with HT1 at Shifa International Hospital, Islamabad and Pak Emirates Military Hospital, Rawalpindi between 2010 and 2023 were included. Information was collected regarding age, gender, symptoms, physical signs, and laboratory results.
UNASSIGNED: The study identified 6 cases of HT1. The average age at presentation was 8 months, with a mean delay in diagnosis of 26.8 months. Males were 4 (66.7%) and 2 (33.3%) were females. All patients had underlying liver disease presenting as abdominal distension with hepatosplenomegaly and accompanying growth failure. Four cases presented with rickets, 2 of which had hypophosphatemic rickets. Urine for succinylacetone was raised in all patients. Alpha fetoprotein was raised but hepatocellular carcinoma was diagnosed in 1 patient only. Low protein diet, and vitamin supplements were used for management. Five of the 6 patients died within 2 years of diagnosis.
UNASSIGNED: Delayed referrals and unavailability of Nitisinone are the major challenges in diagnosing and treating HT1 in Pakistan.
