Albumin‑bilirubin grade and INR for the prediction of esophagogastric variceal rebleeding after endoscopic treatment in cirrhosis

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.

Predictive value of liver fibrosis scores in cardiovascular diseases among hypertensive population

PURPOSE

To explore the predictive value of liver fibrosis scores [fibrosis-4, AST/platelet ratio index, BAAT score (BMI Age ALT TG), and BARD score (BMI AST/ALT Ratio Diabetes)] for the risk of cardiovascular disease (CVD) in a hypertensive population.

METHODS

A total of 4164 hypertensive participants without history of CVD were enrolled in the follow-up. Four liver fibrosis scores (LFSs) were used, including the fibrosis-4 (FIB-4), APRI, BAAT score, and BARD score. The endpoint was CVD incidence which was defined as stroke or coronary heart disease (CHD) during the follow-up period. Cox regression analyses were used to calculate hazard ratios between LFSs and CVD. Kaplan-Meier curve was used to show the probability of CVD in different levels of LFSs. Restricted cubic spline further explored whether the relationship between LFSs and CVD was linear. Finally, we assessed the discriminatory ability of each LFS for CVD was assessed using C -statistics, net reclassification index (NRI), and integrated discrimination improvement (IDI).

RESULTS

During a median follow-up time of 4.66 years, 282 hypertensive participants had CVD. Kaplan-Meier curve showed that four LFSs were associated with CVD and high levels of LFSs significantly increase the probability of CVD in hypertensive population. In the multivariate Cox regression analysis, the adjusted hazard ratios for four LFSs were 3.13 in FIB-4, 1.66 in APRI, 1.47 in BAAT score, and 1.36 in BARD score. Moreover, after adding LFSs to original risk prediction model, we find that all four new models have higher C -statistics of CVD than the traditional model. Furthermore, the results of both NRI and IDI were positive, indicating that LFSs enhanced the effect on the prediction of CVD.

CONCLUSIONS

Our study showed that LFSs were associated with CVD in hypertensive populations in northeastern China. Furthermore, it suggested that LFSs could be a new tool for identifying patients at high risk of primary CVD in a hypertensive population.

The association between liver fibrosis scores and chronic kidney disease

Purpose

This study aimed to clarify the relationship between liver fibrosis scores (Fibrosis-4, BARD score, and BAAT score) and chronic kidney disease (CKD).

Methods

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.

Results

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.

Conclusions

Our study showed that LFSs are associated with CKD among middle-aged populations in rural areas of northeastern China.

Comparison of patients using lamivudine, entecavir, and tenofovir according to liver fibrosis markers fibrosis-4 and aspartate aminotransferase-to-platelet ratio index scores

OBJECTIVES

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.

MATERIALS AND METHODS

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.

RESULTS

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 1^st year, and a plateau was observed in the FIB-4 test after the 2^nd year.

CONCLUSION

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 1^st year.

Impact of liver fibrosis score on the incidence of stroke: A cohort study

PURPOSE

The purpose was to explore the value of liver fibrosis scores (fibrosis-4, BAAT score and BARD score) for incidence risk of stroke in a cohort study.

METHODS

A total of 9088 participants without stroke history enrolled the follow-up. Three liver fibrosis scores (LFSs) including FIB-4, BARD score and BAAT score were adopted. The end point was stroke. Cox regression analysis was used to calculate hazard ratios and 95% confidence interval. Kaplan-Meier curve was used to show the probability of stoke in different levels of LFSs. Subgroup analysis showed the association between LFSs and stroke under different stratification. Restricted cubic spline could further explore whether there is a linear relationship between LFSs and stroke. Finally, we used C-statistics, Net Reclassification Index (NRI) and Integrated Discrimination Improvement (IDI) to assess the discriminatory power of each LFS for stroke.

RESULTS

During a median follow-up time of 4.66 years, 272 participants had a stroke. Through the baseline characteristics, we observed that the stroke incidence population tends to be male and older. It was shown by Kaplan-Meier that three LFSs were associated with stroke and high levels of LFSs significantly increase the probability of stroke. In the univariate Cox regression analysis, the HR of stroke risk was 6.04 (4.14-8.18) in FIB-4, 2.10 (1.45-3.04) in BAAT score and 1.81 (1.38-2.38) in BARD score by comparing the high level with the low level at each LFSs. The adjusted HRs for three LFSs were 2.05 (1.33-3.15) in FIB-4, 1.61 (1.10-2.35) in BAAT score and 1.54 (1.17-2.04) in BARD score by comparing the high group with low group. We found that multivariable-adjusted HRs of three LFSs still increased for stroke when stratified by various factors in subgroup analysis. Moreover, after adding LFSs to original risk prediction model which consist of age, sex, drinking, smoking, hypertension, diabetes, low-density lipoprotein cholesterol, total cholesterol and triglycerides, we found that new models have higher C-statistics of stroke. Furthermore, we calculated Net Reclassification Index (NRI) and Integrated Discrimination Improvement (IDI) to show the ability of LFSs to predict stroke.

CONCLUSIONS

Our study showed that three LFSs were associated with stroke amongst middle-aged populations in rural areas of Northeast China. Furthermore, it suggests that LFSs can be used as a risk stratification tool to predict stroke.

FICK-3 Score Combining Fibrosis-4, Insulin Resistance and Cytokeratin-18 in Predicting Non-alcoholic Steatohepatitis in NAFLD Egyptian Patients

BACKGROUND AND OBJECTIVE

As liver biopsy had multiple procedure-related complications, the introduction of reliable noninvasive tests for accurate discrimination of NASH and liver fibrosis in patients with NAFLD are mandatory. The aim was to elucidate the diagnostic value of fibrosis-4 index (FIB-4), Homeostasis Model Assessment for Insulin Resistance (HOMA-IR) and Cytokeratin-18 fragments (CK18-Fs) in the prediction of NASH and liver fibrosis.

MATERIALS AND METHODS

One hundred Egyptian patients with NAFLD selected from outpatient's clinics of Mansoura University Hospitals underwent histological examination through liver biopsy after approval and consent. The FIB-4, HOMA-IR, CK18-Fs (measured using a human ELISA Kit) and their combination in FICK-3 score were investigated for predicting NASH and liver fibrosis. Receiver operating characteristic (ROC) curves and multivariate logistic regression were analyzed.

RESULTS

In patients with NAFLD, the areas under the ROC were significantly high (AUC: 0.765, 0.700, 0.803, 0.835 for FIB-4, HOMA-IR, CK18-Fs, FICK-3 score, respectively, p = 0.05) displaying a highly statistically significant predictive ability for NASH. Significantly higher AUCs for these parameters were demonstrated predicting early-or advanced-stage liver fibrosis (AUC >0.7, p<0.01). Also, the combined FICK-3 score (the sum of FIB-4 >1.46, HOMA-IR >2.11 and CK18-Fs >307U L-1) had highly significant predictive values for NASH and liver fibrosis and had the best diagnostic accuracy at a cutoff value of 1(AUC >0.8, p<0.001). Contrasted with other diagnostic scores, FICK-3 had the best diagnostic accuracy for detection of fibrotic NASH (AUC = 0.954, p<0.001) and positively correlated with the histological features of NAFLD.

CONCLUSION

The new combination FICK-3 score was a reliable and significant predictor for NASH and liver fibrosis in NAFLD Egyptian patients.

Application of guidelines for the management of nonalcoholic fatty liver disease in three prospective cohorts of HIV-monoinfected patients

OBJECTIVES

Current guidelines recommend use of a diagnostic algorithm to assess disease severity in cases of suspected nonalcoholic fatty liver disease (NAFLD). We applied this algorithm to HIV-monoinfected patients.

METHODS

We analysed three prospective screening programmes for NAFLD carried out in the following cohorts: the Liver Disease in HIV (LIVEHIV) cohort in Montreal, the Modena HIV Metabolic Clinic (MHMC) cohort and the Liver Pathologies in HIV in Palermo (LHivPa) cohort. In the LIVEHIV and LHivPa cohorts, NAFLD was diagnosed if the controlled attenuation parameter (CAP) was ≥ 248 dB/m; in the MHMC cohort, it was diagnosed if the liver/spleen Hounsfield unit (HU) ratio on abdominal computerized tomography scan was < 1.1. Medium/high-risk fibrosis category was defined as fibrosis-4 (FIB-4) ≥ 1.30. Patients requiring specialist referral to hepatology were defined as either having NAFLD and being in the medium/high-risk fibrosis category or having elevated alanine aminotransferase (ALT).

RESULTS

A total of 1534 HIV-infected adults without significant alcohol intake or viral hepatitis coinfection were included in the study. Of these, 313 (20.4%) patients had the metabolic comorbidities (obesity and/or diabetes) required for entry in the diagnostic algorithm. Among these patients, 123 (39.3%) required specialist referral to hepatology, according to guidelines. A total of 1062 patients with extended metabolic comorbidities (any among obesity, diabetes, hypertension and dyslipidaemia) represented most of the cases of NAFLD (79%), elevated ALT (75.9%) and medium/high-risk fibrosis category (75.4%). When the algorithm was extended to these patients, it was found that 341 (32.1%) would require specialist referral to hepatology.

CONCLUSIONS

According to current guidelines, one in five HIV-monoinfected patients should undergo detailed assessment for NAFLD and disease severity. Moreover, one in ten should be referred to hepatology. Expansion of the algorithm to patients with any metabolic comorbidities may be considered.

Characteristics of treatment-naïve HBV-infected individuals with HIV-1 coinfection: A cross-sectional study from South India

Purpose

Human immunodeficiency virus-1 (HIV-1) and hepatitis B virus (HBV) coinfection has become a major health problem across the globe. The increased life expectancy of HIV-1 patients due to antiretroviral therapy has led to the emergence of liver disease as a major mortality factor among them. The purpose of the study was to examine the baseline characteristics of HBV in treatment-naïve HBV/HIV coinfection from southern India compared to monoinfected individuals.

Materials and Methods

The study was cross sectional in design, and samples were examined from 80 HIV-1, 70 HBV and 35 HBV/HIV-coinfected individuals using chemiluminescent microparticle immunoassay, real-time polymerase chain reaction and flow cytometry assays.

Results

There was a significant increase in HBV DNA (P = 0.0001), higher hepatitis B e antigen percentage difference (P = 0.027) and lower CD4 counts (P = 0.01) among the HBV/HIV-coinfected individuals, but no difference in the HIV-1 viral load compared to HIV-1-monoinfected individuals. Also, the aspartate aminotransferase levels, prothrombin time and the international normalised ratio were significantly high among coinfected individuals.

Conclusion

These findings conclude that HIV-1 coinfection can have serious implications on the outcome of HBV-related liver disease. To the contrary, HBV infection had no consequence on the progression of HIV-1 disease but distinctly lowered CD4+ T-cells.

A combination of the on-treatment FIB-4 and alpha-foetoprotein predicts clinical outcomes in cirrhotic patients receiving entecavir

BACKGROUND & AIMS

This study investigates the long-term incidences and predictors of developing hepatocellular carcinoma (HCC), cirrhotic events and mortality in cirrhotic patients receiving entecavir (ETV) therapy.

METHODS

We enrolled 481 nucleos(t)ide analogue-naïve chronic hepatitis B (CHB) patients who had compensated cirrhosis upon entry and had received ETV monotherapy for >12 months.

RESULTS

The 8-year cumulative incidences of developing HCC, cirrhotic events and liver-related mortality were 26.5%, 8.62% and 10.03% respectively. Multivariate analysis revealed that diabetic mellitus (DM), higher fibrosis-4 (FIB-4) and alpha-foetoprotein (AFP) levels at 12 months of treatment, and FIB-4 increase from baseline to 12 months were independent factors of HCC. FIB-4 and AFP levels at 12 months of treatment were also independent factors of cirrhotic events and mortality. FIB-4 cut-off values of 3, 3 and 5 as well as AFP cut-offs of 5, 5, and 9 ng/mL at 12 months of treatment were optimal for predicting HCC, cirrhotic events and mortality during therapy respectively. The FIB-4 and AFP levels at 12 months of treatment were assessed for the combined risk of developing clinical outcomes. The 8-year incidences of HCC, cirrhotic events and liver-related mortality in the subgroups with low FIB-4 and AFP levels were only 5.95%, 1.03% and 2.43% respectively. DM was an independent predictor of HCC and mortality.

CONCLUSION

The combination of FIB-4 and AFP levels at 12 months of treatment is a useful marker for predicting the development of HCC, cirrhotic events and mortality in compensated cirrhotic patients with CHB who are receiving ETV therapy.
