Treatment with UDCA (13 mg/kg/d) and GSH (40 mg/kg/d) for 2 weeks restored normal liver function in the child. However, when the treatment was ceased the levels of serum ALT, AST and TBA returned to abnormally high levels in the patient. Interestingly, treatment with half of the dose of UDCA and GSH also maintained the normal levels of serum ALT and AST, and reduced serum TBA in the child patient.
