Induction of Remission in Autoimmune Hepatitis with Azathioprine Vs. MMF

The goal of this clinical trial is to determine the effectiveness of azathioprine (AZA) versus mycophenolate mofetil (MMF) in inducing remission in treatment-naive patients with autoimmune hepatitis (AIH). The main questions it aims to answer are: Does MMF combined with prednisolone lead to higher remission rates compared to AZA with prednisolone after 24 weeks? Is MMF associated with fewer adverse events than AZA in these patients? Researchers will compare two treatment arms (MMF vs. AZA) to see if MMF leads to improved remission rates and safety outcomes. Primary Outcome Measure: Biochemical remission: The primary outcome is the normalization of liver enzymes (AST, ALT) and IgG levels at 24 weeks. Secondary Outcome Measures: Safety and adverse events: Monitoring and comparing the incidence and severity of side effects between the two groups. Treatment adherence: Evaluating how well patients stick to their assigned treatment regimens. Improvement in quality of life: Assessing changes in the patient\'s quality of life using validated questionnaires. Reversal of fibrosis: Measured by liver stiffness using Fibroscan, aiming for no progression of fibrosis. Participants will: Receive either MMF or AZA, alongside a tapering dose of prednisolone. Be monitored regularly through clinic visits, laboratory tests, and safety assessments to track remission and any adverse events.
