Overview
Immunocompetent patients usually do not require any medical therapy. However, patients with pre-existing liver disease, particularly transplanted patients on immunosuppressive therapy, often develop chronic infection and require antiviral therapy. Antiviral therapy may include either Ribavirin monotherapy (first-line), Pegylated interferon-α monotherapy, or a combination of both.
Medical Therapy
As no specific therapy is capable of altering the course of acute hepatitis E infection, prevention is the most effective approach against the disease. Hospitalization is required for fulminant hepatitis and should be considered for infected pregnant women.[1][2][3]
Acute Hepatitis E
The majority of hepatitis E cases in immunocompetent patients are self-limited. Some patients may require symptomatic treatment, however, HEV infection resolves spontaneously in most cases.[4]
Patients with pre-existing liver conditions, may require treatment with ribavirin. A patient who received treatment with ribavirin showed a normalization of bilirubin levels and a decrease in transaminases.[5][6]
Pregnant women with hepatitis E should be treated, however, a specific treatment regimen has not been established. Ribavirin might be indicated for the treatment of these patients. Despite the teratogenic contra-indications of ribavirin, the risks of HEV infection for the mother and fetus may outweigh the teratogenicity risks of the drug.[7]
Chronic Hepatitis E
Chronic HEV infection often occurs in transplanted patients. In this group of patients, viral clearance is the ideal therapeutic target. Three treatment options are available:
- Reduction of immunosupression
- Pegylated interferon-α
- Ribavirin
Due to the lack of evidence regarding the treatment of chronic hepatitis E, this should be individualized for each patient, according to:
- Stage of liver disease
- Comorbidities
- Range of possible reduction of immunosuppression
- Antiviral drug side-effects
Assessment of a potential reduction of the immunosuppressive therapy, particularly of the T-cell suppression, is the initial approach to treat these patients. 30 % of cases in whom this approach is possible, are cleared from HEV.[8][9]
Patients for whom a reduction of immunosuppression is not possible, and for those who fail to respond to this reduction, antiviral therapy should be considered.[7] This may include pegylated interferon-α monotherapy; ribavirin monotherapy; or a combination of both.[8][10][11][12]
