ABSTRACT Silymarin derived from silybum marianum (milk thistle), a flowering member of the daisy family, may benefit liver function in people infected with the hepatitis C virus. The aims of this pilot study were to assess the efficacy and safety of silymarin on serum hepatitis C virus (HCV) RNA, serum aminotransferases (ALT, AST) levels, liver fibrosis and well-being in patients with chronic hepatitis C (CHC).
This prospective self-controlled trial study was conducted from March to September 2006 at Department of Gastroenterology, Isfahan University of Medical Sciences, Isfahan, Iran. 55 patients with HCV (10 female and 45 male) with a mean age of 31.8 ± 6.4 years (10-67 years) were participated in the study. Patients received 24 weeks of silymarin (630 mg/day). Baseline virological biochemical, liver fibrosis (by a serum fibrosis markers, including YKL-40 and Hyaluronic acid), and SF-36 questionnaire were performed with biochemical tests repeated at the end of the treatment period.
There was statistically difference in mean of ALT (108.7 ± 86.6 vs 70.3 ± 57.7) before and after the treatment (p < 0.001). The means of AST were 99.4 ± 139.7 and 59.7 ± 64.32 before and after the treatment with statistically differences (p = 0.004). After the treatment, nine patients were found with negative HCV-RNA (p = 0.004) and statistically significant improvement in results of liver fibrosis markers were found only in fibrosis group (p = 0.015). Quality of life was improved significantly (p < 0.001).
This study indicated that in patients with CHC performing silymarin (650 mg/day) for 6 months, improved serum HCV-RNA titer, serum aminotransferases (ALT, AST), hepatic fibrosis and patient's quality of life. More future studies are warranted.

    ABSTRACT: The objective of this study is to estimate the average diagnosis and treatment costs of chronic hepatitis B and C, with respect to different therapeutic strategies in Iran. This is a descriptive, analytical, and cross-sectional study carried out on patients with hepatitis B and C, who were referred to the Liver Disease Research Center for Prevention and Treatment of Hepatitis, Isfahan University of Medical Sciences, in 2011. We have estimated the direct medical costs including doctors' fees, cost of para-clinical tests, medical treatments, and liver biopsy, in different treatment strategies. The results of this study showed that the total cost of diagnostic services for hepatitis B virus (HBV) and hepatitis C virus (HCV) patients, with state medical tariffs, was US$ 1499.07 and US$ 2084.89, respectively. The patients' profiles showed that there were currently seven therapeutic strategies available to treat HBV patients. The total cost of treatment strategies varied significantly from US$ 73 to US$ 8256. There were also four main strategies for HCV patients, each of these could be applied in two periods of time. The total cost of these treatment strategies showed a high discrepancy from US$ 242 to US$ 8256. The results confirmed that the total direct medical cost for an HBV patient in Iran exceeded US$ 5.5 Milliard in 2011. The results implied that the market price of direct medical cost of HBV and HCV patients in Iran is much higher than the estimated state costs. These costs would likely be saved or reduced by effective disease management and early prevention.
