ABSTRACT

Background: Isoniazid (INH) is the main drug of choice for tuberculosis. It can be administered singly or in combination with other anti-tuberculosis agents. However, long-term INH therapy may increase the risk of liver toxicity. Previous studies reported that high dose of INH for 1 week can result in steatosis and an increase in sorbitol dehydrogenase (SDH) that indicates mitochondrial damage. Long term use of low dose INH did not induce steatosis in rat liver. This study aimed to determine the INH intraperitoneal dose characteristics in white rat with induced liver fibrosis.

Subjects and Method: This was a randomized controlled trial. A sample of 32 white male rat was selected for this study, and was randomly assigned to 4 groups: (1) INH intraperitoneal 50 mg/kg BW/day; (2) 60 mg/kg BW/day; (3) 70 mg/kg BW/day; (4) 80 mg/kg BW/day. Each group consists of 2 rat. The treatment was given for 2 weeks, 3 weeks, 4 weeks and 5 weeks. After treatment, rat were sacrificed. Liver tissue was taken and histopathological preparations were made by painting with hematoxylineosin for assessment of damage. The independent variable was INH injected intraperitoneally. The dependent variables were hepatocyte ballooning, steatosis, ductular reaction, activity score, and fibrosis. The data were analyzed by paired t test.

Results: High intraperitoneal INH dose (80 mg/kg BW/day) and long treatment duration (5 weeks) were associated with liver damage. Liver tissue in rats in this group showed hepatocyte ballooning prominence (2nd degree), steatosis (3rd degree), and ductus reaction (2nd degree). In addition, liver tissue in rats in that group also showed severe fibrosis (many links or septa fibrous tissue).

Conclusion: High intraperitoneal INH dose (80 mg/kg BW/day) and long treatment duration (5 weeks) are associated with liver damage.
