Abstract
Background and aim
Autoimmune hepatitis (AIH) has variable clinical manifestations and should be considered in the diagnostic work-up of any patient with cryptogenic liver disease. The aim of the study was to determine the clinical, biochemical, histopathological characteristics and treatment outcome of AIH in Egyptian children.
Patients and methods
This observational study was conducted at the Pediatric Hepatology Unit at Cairo University Pediatric Hospital, Egypt. All children (<18 years of age) presenting from 2009 to 2016 with established diagnosis of AIH were included. Medical history, clinical examination, and results of investigations were retrieved from patients’ files. The main outcome measures included the rate of remission, relapses, and mortality.
Results
The study included 34 children with AIH. Twenty patients (58%) presented with chronic liver disease. There was a history of concomitant autoimmune diseases in 5 patients. Transaminases were elevated in all patients. There was synthetic dysfunction in 58%. Twenty-four patients (70.5%) had AIH-1, while nine patients (26.4%) had AIH-2 and one patient (2.9%) had autoantibody negative AIH. Piecemeal necrosis was observed in the liver biopsy of 79% of our cohort. Approximately 80% achieved biochemical remission (88% received combined therapy of prednisolone and azathioprine). About half of the patients developed relapses. One patient died of liver cell failure.
Conclusion
In children with liver disease, a diagnosis of AIH should be considered. In those patients, AIH-1 is more common than AIH-2. Prednisolone monotherapy or combined with azathioprine could achieve remission, but relapse is still common. Treatment non-adherence is the main risk factor for relapse.
