High-density lipoprotein cholesterol and liver disease
Insights
High-density lipoprotein cholesterol (HDLC) levels significantly decrease in patients with various forms of liver disease, including hepatitis and cancer. This finding highlights HDLC as a potential biomarker for liver health.
Area of Science:
- Hepatology
- Clinical Chemistry
- Biomarkers
Background:
- High-density lipoprotein cholesterol (HDLC) is a key lipid parameter.
- The relationship between HDLC and liver disease requires further elucidation.
Purpose of the Study:
- To investigate the association between HDLC concentrations and biopsy-proven liver disease.
- To assess HDLC levels across different liver conditions.
Main Methods:
- 169 patients underwent liver biopsy, serum cholesterol, and HDLC evaluation.
- Serial testing of cholesterol, HDLC, prothrombin, and aminotransferase levels in 24 patients.
Main Results:
- HDLC significantly decreased in acute alcoholic hepatitis, acute viral hepatitis, inactive alcoholic liver disease, chronic active hepatitis, and hepatic neoplasms.
- A strong direct correlation was observed between HDLC and prothrombin activity (r=0.71–0.98).
- Alcohol intake's positive correlation with HDLC is reversed in the presence of liver disease.
Conclusions:
- Reduced HDLC is a significant indicator across diverse liver diseases.
- HDLC serves as a potential biomarker for liver dysfunction and correlates with coagulation status.
Abstract:
To establish whether there is any significant relationship between high-density lipoprotein cholesterol (HDLC) concentrations and biopsy-documented liver disease, 169 patients had needle biopsies, serum cholesterol, and HDLC evaluated. Twenty-four patients had serial cholesterol, HDLC, prothrombin, and aminotransferase levels and activities examined. In both men and women, HDLC decreased strikingly and significantly in acute alcoholic hepatitis and in acute viral hepatitis, compared to controls (p less than 0.001). Men and women with inactive alcoholic liver disease and chronic active hepatitis showed moderate decreased in HDLC (p less than 0.001). Patients with primary and metastatic hepatic neoplasms also had strikingly decreased HDLC (p less than 0.001). Serial testing showed an excellent direct correlation between HDLC and prothrombin activity, r values ranging from 0.71 to 0.98. Although alcohol intake is known to correlate positively with HDLC concentrations, our data shows that this association is not absolute, and in most cases is reversed once liver disease becomes apparent.
