Silybin Supplementation During HCV Therapy With Pegylated Interferon-α2b Plus Ribavirin Reduces Depression and Increases Work Ability

September 30, 2013 updated by: Mariano Malaguarnera, University of Catania

Background: Hepatitis C virus infection and interferon treatment have shown to be risk factors for depression, distressing, psychosocial burden and poor health-related quality of life.

Aim: To determine the effect of a Sylibin-vitamin E-phoshpolipids complex on work ability and whether health related factors (anxiety and depression) were associated with work ability in subjects with chronic hepatitis C treated with Peg-IFN-α and RBV.

Patients and Methods: In this prospective, randomized, placebo controlled, double blind clinical trial, 31 subjects (Group A) with chronic hepatitis, received Pegylated-Interferon-α2b (1.5 mg/kg per week) plus Ribavirin and placebo, while 31 subjects (Group B) received the same dosage of Pegylated-Interferon-α2b plus Ribavirin plus association of Silybin 94 mg + vitamin E 90 mg + phospholipids 194 mg in one pill for 12 months. All subjects underwent laboratory exams and questionnaires to evaluate depression (Beck Depression Inventory - BDI), anxiety (State-trait anxiety inventory - STAI) and work ability (Work ability Index - WAI).

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Work ability index
Time Frame: 12 months
Administration of questionnaire(Work ability Index - WAI)The work ability index is a tool to record the work ability of employees. It aims at identifying, at an early stage, health risks of early retirement an counteracting them. The questionnaire is aimed at: 1) the estimated current and future work ability; 2) diagnosed illness and the number of absenteeism days in the previous year; 3) the estimated sickness-related deterioration in the work performance; 4) mental ability reserves. The WAI evaluates current work ability compared with lifetime and in relation to the demands of the job, number of current diseases diagnosed by a physician, estimated work impairment due to diseases.
