Body Composition Changes in Patients with Chronic Hepatitis C

Area of Science:

• Hepatology
• Body Composition Analysis
• Metabolic Disorders

Background:

• Chronic hepatitis C (CHC) is a significant global health concern.
• Body composition alterations are increasingly recognized in chronic diseases.
• Limited research exists on soft tissue body composition changes in CHC patients compared to healthy individuals.

Purpose of the Study:

• To quantify global and regional body composition differences in CHC patients versus controls.
• To identify associations between body composition changes and CHC.
• To investigate the impact of CHC on soft tissue and bone parameters.

Main Methods:

• Dual-energy X-ray absorptiometry (DXA) was used to assess 60 CHC patients and 60 healthy controls.
• Statistical analysis included Mann-Whitney tests for group comparisons and Spearman's rank correlation for variable associations.
• Correlations were examined with factors including BMI, smoking, fibrosis grade, and treatment regimens.

Main Results:

• CHC patients showed significantly lower total fat mass, trunk fat mass, and percent body fat than controls.
• Reduced fat mass was associated with lower BMI, cigarette smoking, and peginterferon alpha 2a plus ribavirin treatment.
• Bone mineral density (BMD) was lower in CHC patients, correlating with low BMI, smoking, and the same treatment regimen.

Conclusions:

• CHC patients present with an acquired lipodystrophy, particularly affecting the trunk.
• Reduced bone mineral density is also observed in CHC patients compared to controls.
• Low BMI, smoking, and peginterferon alpha 2a/ribavirin therapy are linked to diminished fat mass and BMD in CHC.
