RESUMO
BACKGROUND: Liver biopsy is the gold standard for staging liver fibrosis, but it has numerous drawbacks, mainly associated with bleeding and bile fistula risks. A number of non-invasive techniques have been investigated, but they all have their own disadvantages. To avoid the risks mentioned above and to improve the diagnostic value, we still need to search for a more accurate non-invasive method to evaluate the degree of liver fibrosis. AIM: This study aimed to evaluate the diagnostic performance of FibroTouch versus other non-invasive fibrosis indexes in hepatic fibrosis of different aetiologies. METHODS: This study retrospectively enrolled 227 patients with chronic hepatic liver disease admitted to the first hospital of Lanzhou University from 2017 to 2020. Liver biopsy was performed in all of the patients, and their biochemical indicators were all tested. Non-invasive indexes including the fibrosis index based on four factors (FIB-4), the aminotransferase-to-platelet ratio index (APRI), and the gamma-glutamyl transpeptidase-to-platelet ratio index (GPRI) were all calculated. Transient elastography was performed using FibroTouch. RESULTS: The correlation between FibroTouch and the pathology of liver fibrosis was significantly higher than that between the non-invasive fibrosis indexes and the biopsy results (r = 0.771, p < 0.05). The area under the receiver operating curve (AUC) of FibroTouch was significantly higher than that of FIB-4, APRI, and GPRI for the diagnosis of significant fibrosis (≥ S2 fibrosis stage), advanced fibrosis (≥ S3 fibrosis stage), and cirrhosis (= S4 fibrosis stage) (p < 0.05). The patients were grouped according to different aetiologies. The diagnostic value of FibroTouch had much higher credibility in different fibrosis stages for different causes compared with other non-invasive indexes. The AUC of FibroTouch showed both higher specificity and higher sensitivity than FIB-4, APRI, and GPRI for different liver fibrosis stages with different aetiologies. CONCLUSIONS: FibroTouch demonstrates the highest diagnostic value for liver fibrosis and cirrhosis among non-invasive methods, showing better results than FIB-4, APRI, and GPRI, and surpassed only by liver biopsy. FibroTouch is reliable in assessing liver fibrosis with different aetiologies.

Although serum bile acids and total cholesterol (TC) are closely related to liver cirrhosis, the potential diagnostic value of total bile acid-to-cholesterol ratio (TBA/TC) for liver fibrosis is unclear. The present study aimed to evaluate the value of TBA/TC in the diagnosis of cirrhosis and the relationship between TBA/TC and significant liver fibrosis in chronic hepatitis B virus (HBV) infected patients without cholestasis.667 patients with alkaline phosphatase (ALP) ≤ 1.5 upper limit of normal (ULN) and gamma-glutamyl transferase (GGT) ≤ 3 ULN were rigorously included in this cross-sectional study. Liver biopsy was performed in 32 patients and METAVIR scoring system was used to evaluate liver fibrosis stage. Liver ultrasound elastography was performed in 138 patients, significant fibrosis was defined as fibrosis ≥ F2. Multiple logistic regression as well as receiver operating characteristic (ROC) curves analyses were performed.Compared to patients with non-cirrhosis, TBA and TBA/TC were significantly higher in cirrhosis while TC was significantly lower (all Pâ<â.001). In multivariate analysis, TBA/TC was also independently associated with cirrhosis [odds ratio (OR) = 1.102, 95% confidence interval (CI): 1.085-1.166]. The area under the curve (AUC) of TBA/TC (0.87) was almost equivalent to the aspartate aminotransferase to platelet ratio index (APRI, AUCâ=â0.84) and fibrosis 4 score (FIB-4, AUCâ=â0.80), and the optimal cut-off value for TBA/TC to diagnose cirrhosis was 2.70. Among the patients performed liver biopsy, TBA/TC were significantly higher both in significant fibrosis and cirrhosis as well as significantly correlated with fibrosis stage (all Pâ<â.001). Furthermore, In patients performed liver ultrasound elastography, TBA/TC was also independently associated with significant fibrosis (ORâ=â1.040, 95% CI: 1.001-1.078).Assessment of TBA/TC could serve as an additional marker of significant liver fibrosis and cirrhosis in non-cholestatic chronic HBV infection.
