Effects of silybum marianum on patients with chronic hepatitis C.

ABSTRACT: BACKGROUND: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). METHODS: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. RESULTS: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). CONCLUSIONS: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.

Project description:The glucose oligosaccharide-derived cyclodextrins (CDs) are used for improving bioactive compound production in plant cell cultures because, in addition to their elicitation activity, CDs promote product removal from cells. However, despite these advantages, the industrial application of CDs is hampered by their high market price. A strategy to overcome this constraint was recently tested, in which reusable CD polymers coated with magnetic Fe3O4 nanoparticles were harnessed in Vitis vinifera cell cultures to produce t-resveratrol (t-R). In this study, we applied hydroxypropyl-β-CDs (HPCD) and HPCDs coated with magnetic nanoparticles (HPCD-EPI-MN) in methyl jasmonate (MJ)-treated transgenic Silybum marianum cultures ectopically expressing either a stilbene synthase gene (STS) or a chalcone synthase gene (CHS), and compared their effects on the yields of t-R and naringenin (Ng), respectively. HPCD-EPI-MN at 15 g/L stimulated the accumulation of metabolites in the culture medium of the corresponding transgenic cell lines, with up to 4 mg/L of t-R and 3 mg/L of Ng released after 3 days. Similar amounts were produced in cultures treated with HPCD. Concentrations higher than 15 g/L of HPCD-EPI-MN and prolonged incubation periods negatively affected cell growth and viability in both transgenic cell lines. Reutilization of HPCD-EPI-MN was possible in three elicitation cycles (72 h each), after which the polymer retained 25-30% of its initial efficiency, indicating good stability and reusability. Due to their capacity to adsorb metabolites and their recyclability, the application of magnetic CD polymers may reduce the costs of establishing efficient secondary metabolite production systems on a commercial scale. KEY POINTS: • Long-term transgenic S. marianum suspensions stably produce transgene products • t-R and Ng accumulated extracellularly in cultures elicited with HPCD and HPCD-EPI-MN • The recyclability of HPCD-EPI-MN for metabolite production was proven.
