Overview
Mainstay treatment of autoimmune hepatitis is pharmacotherapy. Corticosteroids alone or in combination with immunosuppressants are commonly used.
Medical Therapy
Mainstay treatment of autoimmune hepatitis is pharmacotherapy. Corticosteroids alone or in combination with immunosuppressants are commonly used.
Acute Pharmacotherapies
- Pharmacologic medical therapies for Autoimmune hepatitis include Prednisone alone and combination of Azathioprine and Prednisone
According to American Association for the Study of Liver Diseases indications for immunosuppressive treatment:
Indications for Immunosuppressive Treatment | ||
---|---|---|
Absolute Indications | Relative Indications | None |
Serum AST >10 fold upper limit of normal range(ULN) | Symptoms like fatigue, arthralgia, jaundice | Asymptomatic with normal or near normal serum
AST and gamma globulin levels |
Serum AST >5 fold ULN | Serum AST and/or gamma globulin less than absolute criteria | Inactive cirrhosis or mild portal inflammation
(portal hepatitis) |
Gamma globulin level>2 fold ULN | Interface hepatitis | Severe cytopenia (white blood cell counts
<2.5 x109/L or platelet counts <50 x 109/L) |
Bridging necrosis or multiacinar
necrosis on histological examination |
Osteopenia, emotional instability, hypertension, diabetes,
or cytopenia (white blood cell counts <2.5 x109/L or platelet counts <50 x109/L) |
complete deficiency of TPMT activity
precludes treatment with azathioprine |
Incapacitating symptoms such as fatigue
and arthralgia |
Vertebral compression, psychosis, brittle diabetes,
uncontrolled hypertension, known intolerances to prednisone or azathioprine |
Recommendations for the Treatment of Autoimmune Hepatitis
- Immunosuppressive treatment based on serum aspartate aminotransferase (AST), serum alanine aminotransferase (ALT), serum gamma-globulin levels, and histological features:[1]
- Prednisone or prednisolone with azathioprine (adults)
- Prednisone with azathioprine or 6-mercaptopurine (children)
- Prednisone or prednisolone alone
- Monitoring for bone disease
- Adjunctive therapies for bone disease (weight-bearing exercise program, vitamin D and calcium supplementation, bisphosphonates)
- Pretreatment vaccination against hepatitis A virus (HAV) and hepatitis B virus (HBV)
- Management of treatment side effects and risks, including during pregnancy
- Alternative drug therapies for suboptimal response (cyclosporine, tacrolimus, or mycophenolate mofetil)
- Hepatic ultrasonography to detect hepatocellular carcinoma (HCC)
- Liver transplantation, management of recurrent disease after transplant with drug therapy and/or retransplantation in certain patients}}
According to American Association for the Study of Liver Diseases, Immunosuppressive Treatment Regimens for Adults with Autoimmune Hepatitis:
- Preferred regimen (1): Prednisone 60mg PO q24h for 7 days ( Preference:Cytopenia, Thiopurine methyltransferase deficiency, Pregnancy, Malignancy, Short-course (<6 months)
- Preferred regimen (2): Prednisone 40mg PO q24h for next 7 days
- Preferred regimen (3): Prednisone 30mg PO q24h for next 7 days
- Preferred regimen (4): Prednisone 30mg PO q24h for next 7 days
- Preferred regimen (5): Prednisone 20mg and below PO q24h for maintenance until endpoint
- Alternative regimen: Combination Therapy which includes Prednisone and Azathioprine
- Alternative regimen (1): Prednisone 30mg PO q24h for 7 days and Azathioprine 50mg q24h for 7 days
- Alternative regimen (2): Prednisone 20mg PO q24h for 7 days and Azathioprine 50mg q24h for next 7 days
- Alternative regimen (3): Prednisone 15mg PO q24h for 7 days and Azathioprine 50mg q24h for next 7 days
- Alternative regimen (3): Prednisone 10mg PO q24h for 7 days and Azathioprine 50mg q24h for maintenance until endpoint

Reasons for Preference | Cytopenia, Thiopurine methyltransferase deficiency,
Pregnancy, Malignancy, Short-course (<6 months) |
Postmenopausal state, Brittle diabetes, Obesity, Acne,
Emotional lability, Hypertension |
Adjunctive therapies:
- Adjunctive therapy is based on medication and complication occurs due to medication
- The regular weight-bearing exercise program, vitamin D, calcium supplementation and bisphosphonates should be taken by patient who is taking corticosteroids for long-term
- Vaccination against hepatitis B virus (HBV) and hepatitis A virus (HAV) should be done as early as possible even before immunosuppression
According to American Association for the Study of Liver Diseases, Immunosuppressive Treatment Regimens for Children in Autoimmune Hepatitis:
Pediatric
- Preferred regimens:
- Initial regimen (1): Prednisone 1- 2 mg/kg (upto60mg/day) PO q24h for 14 days either alone or in combination with azathioprine, 1- 2 mg/kg q24h
- Maintenance regimen (2): Prednisone taper to 0.1 -0.2 mg/kg q24h or 5 mg q24h for 6 -8 weeks
- if added initially, azathioprine at constant dose
- Continue daily prednisone dose with or without azathioprine or switch to alternate day prednisone dose adjusted in response with or without azathioprine
