Summary
Advanced age, low albumin, high alcohol intake, slow acetylator status, and extensive disease are key risk factors for drug-induced liver injury during tuberculosis treatment. Identifying these can help manage potential hepatotoxicity. Keywords: tuberculosis, hepatotoxicity, risk factors, drug-induced liver injury.
Area of Science:
- Hepatology
- Infectious Diseases
- Pharmacology
Background:
- Antituberculosis therapy can cause drug-induced liver injury (hepatotoxicity).
- Several potential risk factors have been proposed, including age, nutritional status, and alcohol consumption.
- This study investigates specific risk factors for hepatotoxicity in patients with pulmonary tuberculosis.
Purpose of the Study:
- To identify significant risk factors for developing hepatotoxicity during short-course antituberculosis therapy.
- To assess the role of age, sex, disease extent, nutritional status, alcohol intake, and acetylator status.
Main Methods:
- A case-control study was conducted.
- Cases (n=86) had drug-induced hepatitis; controls (n=406) completed treatment without hepatitis.
- Variables analyzed included age, BMI, alcohol intake, disease extent, acetylator status, and serum proteins.
Main Results:
- Cases were older with lower serum albumin levels compared to controls.
- High alcohol intake, extensive radiological disease, and slow acetylator phenotype were more prevalent in cases.
- No significant differences were found for sex, BMI, or other analyzed factors.
Conclusions:
- Advanced age, hypoalbuminemia, high alcohol intake, slow acetylator phenotype, and extensive disease are confirmed risk factors for antituberculosis drug-induced hepatotoxicity.
- The presence of multiple risk factors may increase the likelihood of developing liver injury.
- These findings aid in predicting and potentially preventing hepatotoxicity in tuberculosis patients.
