The overall objective of this project is to assess whether Silymarin therapy shortens illness or prevents complications in patients with acute hepatitis. We will specifically compare responses in acute hepatitis patients treated with Silymarin to those given a control preparation of a vitamin supplements in a double blinded, randomized, placebo-controlled trial.

Hepatitis Drug: Silymarin (Silybum marianum) Phase 4

Further study details as provided by University of Maryland:

Primary Outcome Measures:
  • Primary outcomes were symptoms and signs of acute hepatitis and results of liver function tests on days 3, 5 and 7 in the hospital and in the outpatient clinic at weeks 2, 4, and 8.

Secondary Outcome Measures:
  • Side-effects and adverse events were ascertained by self-report on days 3, 5 and 7 in the hospital and in the outpatient clinic at weeks 2, 4, and 8. .

Estimated Enrollment: 200
Study Start Date: July 2003
Estimated Study Completion Date: October 2005
Detailed Description:

The study is designed as a double-blinded placebo controlled trial. We compare a 4 week course of therapy with silymarin tablets and a low-dose vitamin preparation (placebo) and then follow-up for a total of 8 weeks to assess treatment response. Outcomes of our randomized controlled trial are improvement in symptoms and signs, normalization of liver functions, time to resuming normal activities, and and sense of well-being. This protocol follows the standard therapeutic care for acute hepatitis except that the patients will receive either a herbal supplement (silymarin), which many patients are taking anyway, or a vitamin placebo.

Freshly collected serum will be tested for anti-HAV IgM, anti-HBc Igm, anti-HBs, HBs Ag, anti-HCV antibody, HCV-RNA, anti-HDV IgM, anti-HEV IgM, CMV and EBV and for alanine aminotransferase (ALT), AST, direct and total bilirubin.


Ages Eligible for Study:   13 Years to 70 Years   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients admitted to the fever hospital and presenting with symptoms and signs that may be consistent with a diagnosis of acute hepatitis.
  • Recent (<1 month) history of illness.
  • Elevation of ALT > 2.5 normal.
  • At least 13 years old.

Exclusion Criteria:

  • History suggestive of severe drug-induced acute hepatitis.
  • Children 12 years and younger.
  • Pregnant or breastfeeding women
