Aspirin-induced hepatotoxicity and its effect on juvenile rheumatoid arthritis
Insights
Aspirin use in juvenile rheumatoid arthritis (JRA) can elevate liver enzymes (SGOT). Higher doses and serum salicylate levels correlate with these elevations, which often improve with reduced aspirin dosage.
Area of Science:
- Pediatric Rheumatology
- Hepatology
- Pharmacology
Background:
- Juvenile rheumatoid arthritis (JRA) is a chronic inflammatory condition in children.
- Aspirin has been a common treatment for JRA, but potential side effects require monitoring.
- Hepatic involvement can be a concern in children with chronic inflammatory diseases.
Purpose of the Study:
- To investigate the prevalence and degree of hepatic disease evidence in children with JRA treated with aspirin.
- To determine the correlation between aspirin dosage, serum salicylate levels, and liver enzyme elevations.
- To assess the impact of aspirin dose reduction on liver enzyme levels and clinical symptoms.
Main Methods:
- Studied 102 children diagnosed with JRA.
- Monitored serum glutamic oxaloacetic transaminase (SGOT) levels as an indicator of hepatic disease.
- Correlated SGOT levels with aspirin dosage and serum salicylate concentrations.
Main Results:
- Elevated SGOT levels ( > 39 IU/liter) were observed in 59% of the children.
- SGOT elevations correlated significantly with aspirin dose and serum salicylate levels.
- Reduced aspirin dosage led to a decrease in elevated SGOT values.
- SGOT levels above 100 IU/liter were associated with reduced sedimentation rates.
Conclusions:
- Aspirin treatment in JRA is associated with a high prevalence of elevated SGOT levels.
- The degree of liver enzyme elevation is dose-dependent and related to serum salicylate levels.
- Reducing aspirin dosage can normalize SGOT levels and may be associated with clinical improvement in JRA.
Abstract:
Evidence of hepatic disease was sought in 102 children with juvenile rheumatoid arthritis (JRA) who were treated with aspirin. Serum glutamic oxaloacetic transaminase level was elevated (greater than 39 IU/liter) in 59% of the children. The degree and prevalence of SGOT elevations correlated with aspirin dose and serum salicylate level. Nevertheless, increased SGOT values were frequently present in children receiving moderate aspirin doses and having serum salicylate levels less than 25 mg/100 ml. Elevated SGOT values decreased in proportion to the degree of reduction in aspirin dose. The SGOT values above the 100 IU/liter were statistically associated with reduced sedimentation rates. Concomitant improvement in the clinical manifestations of JRA was noted in some children.
