[Can TNF-alpha and IL-6 be helpful in assessment of chronic hepatitis in children?]
Insights
Tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) levels were slightly elevated in children with chronic hepatitis. These inflammatory markers did not significantly correlate with disease activity or liver function, suggesting compensated liver function.
Area of Science:
- Pediatric Gastroenterology
- Immunology
- Hepatology
Context:
- Chronic hepatitis in children is a significant health concern.
- Understanding the role of inflammatory cytokines is crucial for disease management.
- Previous research has explored cytokine profiles in pediatric liver diseases.
Purpose:
- To assess the concentrations of Tumor Necrosis Factor-alpha (TNF-alpha) and Interleukin-6 (IL-6) in children diagnosed with chronic hepatitis.
- To investigate the correlation between these cytokine levels and various laboratory indicators of hepatitis activity and liver function.
- To determine if TNF-alpha and IL-6 levels differ between subgroups of patients based on disease activity, cirrhosis, or portal hypertension.
Summary:
- This study analyzed TNF-alpha and IL-6 levels in 34 children with chronic hepatitis, finding slightly increased concentrations in all patients.
- Correlations between TNF-alpha/IL-6 and laboratory parameters (ALT, prothrombin index, bilirubin, bile acids, alkaline phosphatase, anti-pyrin half-life) were largely non-significant, except for albumin and TNF-alpha.
- No significant differences in TNF-alpha and IL-6 levels were observed between groups with active vs. persistent hepatitis, with vs. without cirrhosis, or with vs. without portal hypertension.
Impact:
- The findings suggest that slightly elevated TNF-alpha and IL-6 levels in pediatric chronic hepatitis may reflect a compensated liver function state.
- This research contributes to the understanding of inflammatory processes in pediatric liver disease.
- Further investigation may elucidate the long-term implications of these cytokine levels in children with chronic hepatitis.
Abstract:
The purpose of the work was an assessment of TNF-alpha and Il-6 concentrations in 34 children with diagnosed chronic hepatitis. In all studied patients the values of TNF-alpha and Il-6 concentration were slightly increased. The correlations calculated between TNF-alpha and Il-6 concentrations calculated between TNF-alpha and Il-6 concentrations and laboratory parameters (laboratory indicators of hepatitis activity--AlAT; liver function indicators--prothrombin index, bilirubin concentration, bile acid concentration, alkaline phosphatase activity, anti-pyrin half-life) were non-significant in Spearman non-parametric test (p > 0.005) except for the correlation between albumin and TNF-alpha concentrations. No statistically significant differences of TNF-alpha and Il-6 concentrations were found between groups of patients with active and persistent hepatitis; groups with and without cirrhosis as well as between groups with and without portal hypertension. Normal or slightly increased TNF-alpha and Il-6 concentrations, observed in chronic hepatitis in children should be explained by compensated liver function in such patients.
