The predominant clinical manifestation was a rash, observed in 57.1% (117\/205) of these cases. Additionally, 19.0% (39\/205) of patients presented with concurrent liver injury. The laboratory parameters white blood cell count, total lymphocyte count, monocyte count, eosinophil count, basophil count, alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase were significantly elevated in patients with hypersensitivity compared to those without. In 38 patients who tested positive for oral antituberculosis drug provocation, 14 (36.8%) were allergic to more than two antituberculosis drugs. Significant risk factors included being female (odds ratio [OR]\u2009=\u20091.387, 95% confidence intervals [CI]: 1.016\u20131.894), under 65\u2009years of age (OR\u2009=\u20091.826, 95% CI: 1.145\u20132.913), existing liver disease (OR\u2009=\u20092.464, 95% CI: 1.822\u20133.333) and a history of allergic diseases (OR\u2009=\u20096.633, 95% CI: 2.681\u201316.406) and were significantly correlated with hypersensitivity to antituberculosis drugs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Hypersensitivity reactions to antituberculosis drugs primarily affect the skin, with significant associations observed with liver injury.
