RESUMEN
Hepatitis C virus (HCV) is a major public health problem being the most common cause of chronic liver disease in Egypt. HCV-induced decompensated liver cirrhosis patients have a median survival of 2 years even with currently used new treatments. Silymarin is the most commonly used herbal product in chronic liver disease for its anti-inflammatory, antiviral, antioxidant, and antifibrotic effects. The aim of this study was to assess the effects of silymarin in high dose on the clinical and biochemical status of chronic HCV-associated decompensated liver cirrhosis. The study was conducted on 62 chronic HCV-decompensated cirrhotic patients. Patients were randomized according to treatment plans: group A, included 31 patients who received silymarin in dose of 1,050 mg/day, and group B, included 31 patients who received silymarin in dose of 420 mg/day. Patients were subjected to baseline history taking, laboratory evaluation, abdominal ultrasound, Child scoring, and quality-of-life (QoL) questionnaire. Follow-up was done every 2 weeks for 12 weeks. Silymarin in high dose had an effect on reducing alanine transaminase, aspartate aminotransferase levels (P ≤ 0.01), as well as improving albumin (P = 0.04), bilirubin (P = 0.02), and international normalized ratio (P = 0.03), thus resulted in improvement in Child score (P = 0.048), however, regular silymarin regimen (420 mg/day) failed to achieve the previous biochemical changes. High-dose regimen of silymarin also had a positive impact on improving QoL. No serious adverse events were reported. Silymarin in high dose is a good choice for improvement of liver biochemical profile and QoL in chronic HCV cirrhotic patients.
