BACKGROUND: Both tenofovir alafenamide (TAF) and tenofovir disoproxil fumarate (TDF) are the first-line treatments for chronic hepatitis B (CHB). We have showed switching from TDF to TAF for 96 weeks resulted in further alanine aminotransferase (ALT) improvement, but data remain lacking on the long-term benefits of TDF switching to TAF on hepatic fibrosis.
OBJECTIVE: To assess the benefits of TDF switching to TAF for 3 years on ALT, aspartate aminotransferase (AST), and hepatic fibrosis improvement in patients with CHB.
METHODS: A single center retrospective study on 53 patients with CHB who were initially treated with TDF, then switched to TAF to determine dynamic patterns of ALT, AST, AST to platelet ratio index (APRI), fibrosis-4 (FIB-4) scores, and shear wave elastography (SWE) reading improvement at switching week 144, and the associated factors.
RESULTS: The mean age was 55 (28-80); 45.3%, males; 15.1%, clinical cirrhosis; mean baseline ALT, 24.8; AST, 25.7 U/L; APRI, 0.37; and FIB-4, 1.66. After 144 weeks TDF switching to TAF, mean ALT and AST were reduced to 19.7 and 21, respectively. From baseline to switching week 144, the rates of ALT and AST < 35 (male)/25 (female) and < 30 (male)/19 (female) were persistently increased; hepatic fibrosis was also improved by APRI < 0.5, from 79.2% to 96.2%; FIB-4 < 1.45, from 52.8% to 58.5%, respectively; mean APRI was reduced to 0.27; FIB-4, to 1.38; and mean SWE reading, from 7.05 to 6.30 kPa after a mean of 109 weeks switching. The renal function was stable and the frequency of patients with glomerular filtration rate > 60 mL/min was increased from 86.5% at baseline to 88.2% at switching week 144.
CONCLUSIONS: Our data confirmed that switching from TDF to TAF for 3 years results in not only persistent ALT/AST improvement, but also hepatic fibrosis improvement by APRI, FIB-4 scores, as well as SWE reading, the important clinical benefits of long-term hepatitis B virus antiviral treatment with TAF.

OBJECTIVE: Non-invasive tests (NITs) for liver fibrosis have been recognized for their clinical utility in metabolic dysfunction-associated steatotic liver disease (MASLD). However, their diagnostic efficacy in detecting liver fibrosis is notably reduced in patients with alcohol-related liver disease. Therefore, ascertaining the reliability of NITs in patients with MASLD with moderate alcohol intake (MetALD) is essential.
METHODS: In this cross-sectional study, we reviewed data from 7,918 health check-up participants who underwent both magnetic resonance elastography (MRE) and ultrasound for the diagnosis of hepatic steatosis. The participants were categorized into MASLD and MetALD groups, and the performance of fibrosis-4 index (FIB-4) and NAFLD fibrosis score (NFS) were assessed. Advanced hepatic fibrosis (F3) was defined as MRE ≥3.6 kPa.
RESULTS: The prevalence of MetALD was 5.8% in this health check-up cohort, and 1.5% of these patients exhibited advanced hepatic fibrosis. Both MetALD and MASLD displayed similar metabolic profiles and hepatic fibrosis burdens. The diagnostic performance of FIB-4 and NFS for MRE ≥3.6 kPa showed no noticeable differences in the area under the receiver-operating characteristic values between the two groups (0.85 vs. 0.80 in FIB-4). Moreover, the sensitivity (71.4%), specificity (77.3%), and both positive (4.6%) and negative (99.4%) predictive values of NITs for MetALD closely mirrored those observed for MASLD.
CONCLUSIONS: FIB-4 performed well for the initial screening of advanced hepatic fibrosis in MetALD, demonstrating reasonable sensitivity and negative predictive values.
UNASSIGNED: In this cross-sectional study, data from 7,918 participants who underwent MRE were analyzed to assess the performance of fibrosis-4 (FIB-4) and non-alcoholic fatty liver disease fibrosis scores in metabolic dysfunction-associated steatotic liver disease (MASLD) and MASLD with moderate alcohol intake (MetALD). We found that FIB-4 had high diagnostic accuracy in the newly identified MetALD group, similar to that in the MASLD population. These results highlight the potential of FIB-4 as a reliable screening tool for MetALD, even when specific subgroups are considered. Therefore, FIB-4 is a valuable screening tool for identifying advanced fibrosis in the MetALD population.

BACKGROUND: Black patients have higher hepatocellular carcinoma (HCC)-related mortality than White patients and more often develop HCC in non-cirrhotic liver. HCC surveillance is primarily directed toward cirrhotic patients. We aimed to characterize HCC in non-cirrhotic patients and to identify factors associated with HCC beyond Milan criteria.
METHODS: Demographic, imaging, laboratory, and pathology data of HCC patients at our institution, 2003-2018, were reviewed, retrospectively. Race/ethnicity were self-reported. Cirrhosis was defined as a Fibrosis-4 score ≥3.25.
RESULTS: Compared to 1146 cirrhotic patients, 411 non-cirrhotic patients had larger tumors (median 4.7 cm vs. 3.1 cm, p < 0.01) and were less likely to be within Milan criteria (42.6% vs. 57.7%, p < 0.01). Among non-cirrhotic patients, Black patients had larger tumors (4.9 cm vs. 4.3 cm, p < 0.01) and a higher percentage of poorly differentiated tumors (39.4% vs. 23.1%, p = 0.02). Among cirrhotic patients, Black patients had larger tumors (3.3 cm vs. 3.0 cm, p = 0.03) and were less likely to be within Milan criteria (52.3% vs. 83.2%, p < 0.01). In multivariable analysis, lack of commercial insurance (OR 1.45 [CI 95% 1.19-1.83], p < 0.01), male sex (OR 1.34 [CI 95% 1.05-1.70], p < 0.01), absence of cirrhosis (OR 1.58 [CI 95% 1.27-1.98], p < 0.01) and Black race/ethnicity (OR 1.34 [CI 95% 1.09-1.66], p = 0.01) were associated with HCC beyond Milan criteria. Black patients had lower survival rates than other patients (p < 0.01).
CONCLUSIONS: Non-cirrhotic patients had more advanced HCC than cirrhotic patients. Black patients (with or without cirrhosis) had more advanced HCC than comparable non-Black patients and higher mortality rates. Improved access to healthcare (commercial insurance) may increase early diagnosis (within Milan criteria) and reduce disparities.

Rebleeding following endoscopic treatment in patients with cirrhosis is a serious life-threatening complication. In the present study, a novel, reliable and non-invasive score for prediction of rebleeding following endoscopic therapy for esophagogastric variceal bleeding (EGVB) was developed. The present retrospective study recruited cirrhotic patients with EGVB (n=596) who underwent endoscopic therapy. Patients hospitalized from January 2015 to January 2020 were grouped into a training (n=437) cohort to develop the new score and those hospitalized from February 2020 to February 2022 were grouped into a validation (n=159) cohort to validate the score. The international normalized ratio (INR) and albumin-bilirubin (ALBI) grade were used to develop the INR-ALBI (IALBI) score to predict risk of rebleeding. In the training cohort, the prognostic performance of the IALBI score and other ALBI-associated scores (modified ALBI, platelet-ALBI and ALBI-fibrosis-4) at 1, 3 and 12 months was assessed using receiver operating characteristic (ROC) curve and Kaplan-Meier analysis. At each time point, most areas under the ROC curve of IALBI were higher than those of other ALBI-associated scores, particularly for prediction of early rebleeding. At 1 month, the rebleeding rates of patients with IALBI grade 2 and 3 were ~10.0- and 19.5-times higher than those of patients with grade 1, respectively. The negative predictive value (NPV) of IALBI for the training and validation cohort at 1 month was 100.0 and 97.8%, respectively. For viral and non-viral patients in the training cohort, IALBI showed good predictive ability and NPV for early rebleeding. The IALBI grading system successfully assessed rebleeding, particularly early rebleeding, in cirrhotic patients with EGVB following endoscopic therapy IALBI grade 1, predicted low risk of rebleeding and may not require endoscopic treatment again in the short-term.

UNASSIGNED: Biliary atresia (BA) is a blockage in the tubes (ducts) that carry bile from the liver to the gallbladder. The aspartate aminotransferase to platelet ratio (APRI), and Fibrosis-4 (FIB-4) scores are commonly used compound surrogates for advanced fibrosis. However, the use of APRI and FIB-4 entails a risk of overestimating the fibrosis stage due to the impact of necroinflammatory activity on transaminases. So, we determined the optimal cutoff values of the APRI and FIB-4 indices in prediction of fibrosis in BA patients. The aim of the study was to evaluate the validity of the APRI and FIB-4 indices in prediction of fibrosis in patients with BA.
UNASSIGNED: A cross sectional hospital-based study was conducted on 121 children complaining of BA attending the National Liver Institute, Menoufia University, Shebin Elkom, Menoufia, Egypt, during the period from January 2022 to February 2023.
UNASSIGNED: The APRI score was significantly higher among neglected BA than BA type II a, BA type III, type II b and type I (p = 0.001). Also FIB-4 was significantly higher among neglected BA than BA type II a, BA type II b, type III and type I (p = 0.001). Receiver operating characteristic (ROC) curve analysis showed that the cutoff point of the APRI score in prediction of fibrosis in patients with BA was 1.29, with sensitivity of 88.6% and specificity of 76.0%, while the cutoff point of FIB-4 in prediction of fibrosis in patients with BA was 9.82 with sensitivity of 89.0% and specificity of 70.0%.
UNASSIGNED: Our study confirms that FIB-4 and APRI scores are both able to predict severe fibrosis. APRI score and FIB-4 are good non-invasive alternatives to liver biopsy in the detection of liver fibrosis and its extent in patients with BA.

UNASSIGNED: In a longitudinal study, we aimed to assess the correlation between ultrasound transient elastography (TE), serum ferritin (SF), liver iron content (LIC) by magnetic resonance imaging (MRI) T2* along with the fibrosis-4 (FIB-4) score as a screening tool to detect significant liver fibrosis among chronically transfusion-dependent beta-thalassemia (TDT) patients.
UNASSIGNED: The study was conducted at a tertiary health center treating TDT patients. Transient elastography was performed within 3 months of Liver MRI T2* examinations at the radiology department over a median of one-year duration. T-test for independent data or Mann-Whitney U test was used to analyze group differences. Spearman correlation with linear regression analysis was used to evaluate the correlation between TE liver stiffness measurements, Liver MRI T2* values, and SF levels.
UNASSIGNED: In this study on 91 patients, the median age (IQR) of the subjects was 33 (9) years, and the median (IQR) body mass index was 23.8 (6.1) kg/m2. Median (IQR) TE by fibroscan, MRI T2*(3T), Liver iron concentration (LIC) by MRI Liver T2*, and SF levels were 6.38 (2.6) kPa, 32.4 (18) milliseconds, 7(9) g/dry wt., and 1881 (2969) ng/mL, respectively. TE measurements correlated with LIC g/dry wt. (rS =0.39, p=0.0001) and with SF level (rS =0.43, P=0.001) but not with MRI T2* values (rS =-0.24; P=0.98).
UNASSIGNED: In TDT patients, liver stiffness measured as TE decreased significantly with improved iron overload measured as LIC by MRI and SF levels. However, there was no correlation of TE with the fibrosis-4 (FIB-4) score.

It was intended to assess the efficacy of lamivudine, entecavir, and tenofovir regimens in the management of chronic hepatitis B (CHB) guided by Fibrosis-4 (FIB-4) and aspartate aminotransferase-to-platelet ratio index (APRI) scores.
Our study was conducted on patients who applied to the hepatitis outpatient clinic between 2008 and 2015 retrospectively. Lamivudine, entecavir, and tenofovir regimens used in the practice of CHB cases were compared by measuring noninvasive FIB tests.
Entirely 199 patients involved in the research were evaluated in three treatment arms; 48 used lamivudine, 46 used entecavir, and 105 used tenofovir. Similar statistical characteristics were observed between research arms regarding age, gender, and alanine aminotransferase normalization by years (P > 0.05). Totally 5 (13.5%) of patients developed Hepatitis B e antigen (HBeAg) seroconversion among 36 HBeAg positivity, and similar statistical features were seen by comparing the groups (P > 0.05). In the entecavir and tenofovir arms, a significant decrease was seen in FIB-4, and APRI index values in the 1st year of treatment (P < 0.001). At the graph curve, a plateau was observed in the APRI test after the 1st year, and a plateau was observed in the FIB-4 test after the 2nd year.
Consistent with the study outcome, when we consider FIB regression, tenofovir and entecavir regimens were found more effective than lamivudine. In addition, entecavir was more effective than the other two drugs after the 1st year.

UNASSIGNED: This study aimed to clarify the relationship between liver fibrosis scores (Fibrosis-4, BARD score, and BAAT score) and chronic kidney disease (CKD).
UNASSIGNED: We collected a range of data from 11,503 subjects (5,326 men and 6,177 women) from the rural regions of Northeastern China. Three liver fibrosis scores (LFSs) including fibrosis-4 (FIB-4), BARD score, and BAAT score were adopted. A logistic regression analysis was used to calculate odds ratios and the 95% confidence interval. A subgroup analysis showed the association between LFSs and CKD under different stratifications. Restricted cubic spline could further explore whether there is a linear relationship between LFSs and CKD. Finally, we used C-statistics, Net Reclassification Index (NRI), and Integrated Discrimination Improvement (IDI) to assess the effect of each LFS on CKD.
UNASSIGNED: Through the baseline characteristics, we observed that LFSs were higher in the CKD population than in non-CKD. The proportion of participants with CKD also increased with LFSs. In a multivariate logistic regression analysis, the ORs of CKD were 6.71 (4.45-10.13) in FIB-4, 1.88 (1.29-2.75) in the BAAT score, and 1.72 (1.28-2.31) in the BARD score by comparing the high level with the low level in each LFSs. Moreover, after adding LFSs to the original risk prediction model, which consisted of age, sex, drinking, smoking, diabetes, low-density lipoprotein cholesterol, total cholesterol, triglycerides, and mean waist circumference, we found the new models have higher C-statistics. Furthermore, NRI and IDI both indicate LFSs had a positive effect on the model.
UNASSIGNED: Our study showed that LFSs are associated with CKD among middle-aged populations in rural areas of northeastern China.

OBJECTIVE: Oxaliplatin can lead to hepatic sinusoidal injury, called hepatic sinusoidal obstruction syndrome (SOS), resulting in portal hypertension-related complications. This could worsen the clinical course of the patients treated with oxaliplatin. Early diagnosis is challenging. We explored predictive markers of oxaliplatin-induced collateral vessels.
METHODS: Patients who received oxaliplatin-based chemotherapy were retrospectively screened. We evaluated their laboratory findings and spleen size on computed tomography immediately before oxaliplatin-based chemotherapy and after 6 months of treatment. The primary outcome was collateral vessel development, as a surrogate marker for oxaliplatin-induced SOS in patients who underwent oxaliplatin-based chemotherapy. The secondary outcome was the identification of factors that predicted the development of collateral vessels.
RESULTS: We enrolled 161 patients who received oxaliplatin-based chemotherapy. They had a median age of 69 years, and 63.3% were men. Collateral vessels developed in nine (5.6%) patients during the study period. After oxaliplatin-based chemotherapy, the spleen size increased in 104 patients (64.6%), with a ≥ 30% increase in 19.4% of the patients. Univariate analysis showed that the Fibrosis-4 (FIB-4) index (≥ 1.76; OR 9.17), aspartate aminotransferase:platelet ratio index (APRI) (≥ 0.193; OR 9.62), cumulative dose of oxaliplatin (≥ 1000 mg; OR 8.43), and increase in spleen size (≥ 30%; OR 6.01) were significant risk factors for collateral vessel development. Multivariate analysis after stepwise selection revealed that the FIB-4 index and spleen size were significant independent predictive factors.
CONCLUSIONS: A ≥ 1.76 increase in the FIB-4 index and a ≥ 30% increase in spleen size after 6 months of oxaliplatin-based chemotherapy were significant predictive markers for collateral vessel development.
