Postgraduate Course Notes – Hepatitis Module

Notes from NASPGHAN’s postgraduate course:

Refractory Autoimmune Hepatitis (AIH):  — Vicky Ng

Dr. Ng’s talk started with an overview of AIH and referred to AASLD guidelines: Diagnosis and Management of Autoimmune Hepatitis – AASLD

Recommendations included the following:

  • Cholangiography for all new cases of AIH
  • Starting azathioprine after seeing some improvement in transaminases with steroids
  • Monitoring for HCC
  • Monitor bone density/bone protection strategies discussed
  • Long term Rx needed in majority, though small number may be able to come off therapy if doing well for 2 years and normal liver biopsy

Refractory mgt:

  • This is applicable in 15-20% of patients
  • Reasons for refractory disease: non response, drug intolerance, non-compliance, overlap syndrome, comorbidities
  • If treatment failure, options could include increasing steroids and azathioprine.  If concerns for decompensation, refer for liver transplant evaluation.
  • NO standard Rx for refractory, but consider MMF (mycophenolate mofetil), cyclosporin (CYA), or tacrolimus (FK)
  • MMF most promising agent for refractory disease.  Small studies of MMF in adults/pediatrics indicates response in about 2/3rds of patients; best for those intolerant to azathioprine & helpful in dropping steroid dosing.  In pediatrics, a starting dose of 20 mg/kg/day is typical and increasing up to 40 mg/kg/day.  Pediatric study: 18/26 (69%) with response and 14/18 with normal AST w/in 2 months.
  • Tacrolimus –small study showed about ~90% response.  Dose was 0.1 mg/kg/day & target trough was 3 ng/mL
  • Briefly discussed budesonide.  More data in pediatrics needed.
