Decreased activities of daily living is a strong risk factor for liver injury by anti-tuberculosis drugs.

We evaluated the association between activities of daily living and drug-induced liver injury by anti-tuberculosis drugs. This retrospective cohort study included adult inpatients with newly diagnosed smear-positive lung tuberculosis treated with standard regimen in two hospitals. (n = 346; 63.6 ± 20.3 years old; 106 (30.6%) females). Activities of daily living was divided into 'independent' (Barthel Index (BI) 80-100, 60.4%) and 'decreased' (BI 0-75, 39.6%) categories. Liver injury was defined as the withdrawal or change of treatment regimen on the basis of the following criteria: serum transaminase concentrations were more than three times the upper limit of normal range with jaundice and/or hepatitis symptoms, or more than five times the upper limit of the normal range. Compared with 'independent' patients, patients with 'decreased' activities of daily living had odds ratios for liver injury of 4.2 (P < 0.001) in univariate analysis and 5.7 (P = 0.002) in logistic regression analysis after adjusting for other risk factors. Decreased activity of daily living is a strong risk factor for liver injury among adult inpatients with newly diagnosed smear-positive lung tuberculosis treated using a standard regimen. © 2013 The Authors.
