Influencing factors for drug-induced liver injury among patients with pulmonary tuberculosis in Ningbo City / 预防医学

ABSTRACT

Objective@#To investigate the factors affecting drug-induced liver injury among patients with pulmonary tuberculosis in Ningbo City from 2015 to 2019, so as to provide insights into the prevention of drug-induced liver injury.@*Methods@#Demographic features, presence of drug-induced liver injury, and disease history prior to anti-tuberculosis therapy were captured from patients with pulmonary tuberculosis in Ningbo City from 2015 to 2019 through the Tuberculosis Management Information System of the Chinese Disease Control and Prevention Information System and Ningbo Regional Diagnosis and Treatment Information Platform. Factors affecting drug-induced liver injury was identified using the multivariable logistic regression analysis.@*Results@#A total of 9 397 patients with pulmonary tuberculosis were enrolled, among whom 66.43% ( 6 242 case ) were male, 65.89% ( 6 192 cases ) were at ages of <60 years, and 92.35% ( 8 678 cases ) were treatment-naïve. There were 1 425 patients with drug-induced liver injury (15.16% incidence), including 729 cases with grade 1 (51.16%), 24 cases with grade 2 (1.68%), 7 cases with grade 3 (0.49%), 7 cases with grade 4 ( 0.49% ), and 658 cases with ungraded drug-induced liver injury ( 46.18% ). The median duration between drug administration and development of drug-induced liver injury was 24 ( interquartile range, 44 ) days. Multivariable logistic regression analysis identified treatment-naïve ( OR=1.464, 95%CI 1.153-1.859 ) and history of liver disease ( OR=2.001, 95%CI 1.709-2.342) as risk factors for drug-induced liver injury in patients with pulmonary tuberculosis.@*Conclusion@#The incidence of drug-induced liver injury was 15.16% among pulmonary tuberculosis patients in Ningbo City from 2015 to 2019. Treatment-naïve and a history of liver disease are associated with drug-induced liver injury among patients with pulmonary tuberculosis.
