Effect of silymarin for the prevention of drug-induced liver injury in tuberculosis patients
Abstract
To evaluate the effect of silymarin for the prevention of antituberculosis drug-induced liver injury 307 new tuberculosis patients were enrolled to the retrospective cohort study. The patients of silymarin group (n = 204) received silymarin in a dose of 105 mg per day from the start of anti-tuberculosis treatment; patients of control group (n = 103) received only anti-tuberculosis drugs. The follow-up period were equal to the duration of intensive phase of anti-tuberculosis treatment. Drug-induced liver injury was registered in 20.1% (41/204) and 33.0% (34/103) in silymarin and control groups, respectively (р = 0.017, RR 1.64, 95%CI 1.11–2.42). The effect of silymarin was different in groups of high and low individual risk of drug-induced liver injury defined by validated risk assessment scale. Only in patients with high individual risk the rate of drug-induced injury in silymarin group was significantly low: 23.2% (13/56) vs 65.8% (25/38) in control group (р < 0.001, RR = 2.83, 95%CI 1.67–4.81). In patients with low individual risk silymarin had no protective effect (19.2% and 12.8% cases of druginduced injury in silymarin and control groups, p = 0,320). So, silymarin preventive use indicated only for TB patients with high individual risk of drug-induced liver injury.
