Insights
Hepatic artery resistive index (HARI) more accurately identifies liver fibrosis than cystatin C (CysC). However, CysC better indicates the severity of liver cirrhosis progression.
Area of Science:
- Hepatology
- Nephrology
- Medical Diagnostics
Background:
- Cystatin C (CysC) and hepatic artery resistive index (HARI) are potential biomarkers for chronic liver disease progression.
- Assessing their clinical utility in liver cirrhosis is crucial.
Purpose of the Study:
- To evaluate the clinical significance of CysC and HARI in assessing liver fibrosis in patients with liver cirrhosis.
- To compare the efficacy of CysC and HARI in differentiating healthy individuals from those with liver fibrosis.
Main Methods:
- A cross-sectional study involving 63 liver cirrhosis patients and 30 healthy controls.
- Measurement of CysC levels and HARI values.
- Statistical analysis including correlation and receiver operating characteristic (ROC) curve analysis.
Main Results:
- Significantly higher CysC levels and increased HARI values were observed in liver cirrhosis patients compared to controls (p=0.036 and p<0.001, respectively).
- A significant correlation was found between HARI and CysC in the study group.
- HARI demonstrated a greater area under the curve than CysC for distinguishing healthy subjects from patients with fibrosis.
- CysC showed statistically significant correlations with Child-Pugh stages and MELD score.
Conclusions:
- HARI is a more accurate parameter than CysC for discriminating healthy individuals from those with liver fibrosis.
- CysC may serve as a better indicator for assessing the stage of liver cirrhosis.
Background:
Data suggest cystatin C (CysC) levels and hepatic artery resistive index (HARI) correspond to the progression of chronic liver disease. We aimed to evaluate the clinical significance of these parameters in assessment of fibrosis in patients with liver cirrhosis.
Methods:
The cross-sectional study included 63 patients with liver cirrhosis. A control group consisted of 30 age- and gender-matched healthy persons.
Results:
We confirmed significantly higher values of CysC in patients with cirrhosis compared to control group (p = 0.036). Average value of HARI in the examined group was increased (0.72 ± 0.06) and there was the statistically significant difference compared to controls (0.66 ± 0.03) (p < 0.001). We found statistically significant correlation between HARI and CysC in the study group. Analyzing the possibility of distinguishing healthy subjects from patients with fibrosis, we have found that the area under the curve is far greater in the HARI index than CysC. Comparison of CysC among Child⁻Pugh stages and correlation with a model for end-stage liver disease (MELD) score showed statistically significant results.
Conclusion:
We confirmed HARI is a more accurate parameter than CysC in discriminating healthy subjects from patients with fibrosis, while CysC could be a better indicator of the stage of liver cirrhosis.
