For patients with chronic hepatitis C who are not candidates for interferon-based treatment, an alternative might be suppressive treatment
with a well-tolerated agent that reduces inflammation and might therefore slow progression of fibrosis. Vitamin E has previously been shown to reduce
ALT levels among a small group of patients with chronic hepatitis C. Omega-3 fatty acid (O3FA) concentrate (Omacor‚) has been shown to reduce disease
activity in chronic conditions such as arthritis and IBD. AIM: to determine whether short-term treatment with vit E or O3FA reduces serum ALT levels
among patients with chronic hepatitis C.
METHODS: Patients had histological evidence of chronic hepatitis, detectable
serum HCV RNA, and ALT at least 2X normal. They had received no antiviral, herbal, or vitamin treatment within 30 days of entry. In random order, they
were given vit E 400 IU BID x 12 wk, then O3FA 2 g BID x 12 wk, or vice versa, with 12-wk observation after each. Blood tests were monitored at 0, 2,
4, 8, and 12 wk of treatment, and at 12 wk after treatment.
RESULTS: 20 patients were enrolled, most having failed interferon; 13 have
completed treatment and follow-up on vit E, and 10 on O3FA. On vit E, median ALT was ~60% of baseline, starting at 2 wk; 11 of 13 patients had a reduction
in ALT. On O3FA, median ALT gradually declined to ~60% of baseline at 12 wk; 7 of 10 had reduced ALT. Median ALT relapsed toward baseline after each
treatment. Median ALT (% of baseline): see table. Among 7 patients on vit E with paired PCR results available thus far (Chiron bDNA assay), we found no
significant changes in RNA levels on treatment compared to baseline.
CONCLUSIONS: 1) Both vitamin E and O3FA (Omacor‚) can reduce ALT levels among
patients with chronic hepatitis C. 2) The progressive decline in ALT over 12 weeks on O3FA suggests that longer treatment might be beneficial. 3) These
agents warrant further study as alternative suppressive treatments for patients who are not candidates for conventional therapy. Grant support was
