New simple prognostic score for primary biliary cirrhosis: Albumin-bilirubin score

Colectomy in patients with liver disease: albumin-bilirubin score accurately predicts outcomes

BACKGROUND

Patients with liver disease undergoing colectomy have higher rates of complications and mortality. The Albumin-Bilirubin score is a recently developed system, established to predict outcomes after hepatectomy, that accounts for liver dysfunction.

METHODS

All patients undergoing colectomy were identified in the 2015-2018 American College of Surgeons National Surgical Quality Improvement Program colectomy-targeted database. Demographics and outcomes were compared between patients with Albumin-Bilirubin Grade 1 vs. 2/3. Multivariable regression was performed for outcomes including colorectal-specific complications. Areas under the receiver operative characteristic curves were calculated to determine accuracy of the Albumin-Bilirubin score.

RESULTS

Of 86,273 patients identified, 48% (N = 41,624) were Albumin-Bilirubin Grade 1, 45% (N = 38,370) Grade 2 and 7% (N = 6,279) Grade 3. Patents with Grade 2/3 compared to Grade 1 had significantly increased mortality (7.2% vs. 0.9%, p < 0.001) and serious morbidity (31% vs. 12%, p < 0.001). Colorectal-specific complications including anastomotic leak (3.7% vs. 2.8%, p < 0.001) and prolonged ileus (26% vs. 14%, p < 0.001) were higher in patients with Grade 2/3. Grade 2/3 had increased risk of mortality (odds ratio 3.07, p < 0.001) and serious morbidity (1.78, p < 0.001). Albumin-Bilirubin had excellent accuracy in predicting mortality (area under the curve 0.81, p < 0.001) and serious morbidity (0.70, p < 0.001).

CONCLUSION

Albumin-Bilirubin is easily calculated using only serum albumin and total bilirubin values. Grade 2/3 is associated with increased rates of mortality and morbidity following colectomy. Albumin-Bilirubin can be applied to risk-stratify patients prior to colectomy.

Role of albumin-bilirubin score in non-malignant liver disease

The albumin-bilirubin (ALBI) score, which was proposed to assess the prognosis of patients with hepatocellular carcinoma, has gradually been extended to other liver diseases in recent years, including primary biliary cholangitis, liver cirrhosis, hepatitis, liver transplantation, and liver injury. The ALBI score is often compared with classical scores such as the Child-Pugh and model for end-stage liver disease scores or other noninvasive prediction models. It is widely employed because of its immunity to subjective evaluation indicators and ease of obtaining detection indicators. An increasing number of studies have confirmed that it is highly accurate for assessing the prognosis of patients with chronic liver disease; additionally, it has demonstrated good predictive performance for outcomes beyond survival in patients with liver diseases, such as decompensation events. This article presents a review of the application of ALBI scores in various non-malignant liver diseases.

Clinical Significance of Albumin-Bilirubin Grade in Thoracic Esophageal Squamous Cell Carcinoma

INTRODUCTION

The albumin-bilirubin (ALBI) score evaluates liver dysfunction severity. However, this score had prognostic effects in patients with hepatocellular, pancreatic, and gastric carcinomas. We aimed to assess the predictive value of the ALBI score in patients with esophageal squamous cell carcinoma (ESCC).

METHODS

Data from 154 patients with ESCC who consecutively underwent neoadjuvant chemotherapy (NAC) and subtotal esophagectomy were retrospectively investigated. The ALBI score was calculated as pre-NAC ALBI and categorized into grades 1, 2a, 2b, and 3; low-ALBI group (n = 134) was assigned with ALBI grade 1 and the other grades were assigned to the high-ALBI group (n = 20).

RESULTS

The pre-NAC ALBI was significantly associated with relapse-free survival (RFS) and overall survival (P = 0.003 and P = 0.014, respectively). Based on multivariate analysis, pre-NAC ALBI, pathological T factor, and N factor were identified as independent prognostic factors for poor RFS. Multivariate and univariate analyses limited to factors were obtained before treatment, indicating high pre-NAC ALBI as an independent prognostic factor of poor overall survival (P = 0.039) and RFS (P = 0.008). With respect to pathological response to NAC, patients in the high pre-NAC ALBI group had a significantly lower response than patients in the low pre-NAC ALBI group (P = 0.010).

CONCLUSIONS

Our results suggested that the pre-NAC ALBI marker predicts the long-term outcome and pathological response to NAC in patients with ESCC consecutively undergoing NAC and a subtotal esophagectomy.

Extracellular volume by dual-energy CT, hepatic reserve capacity scoring, CT volumetry, and transient elastography for estimating liver fibrosis

Our purpose was to compare the efficacy of liver and splenic volumetry (LV and SV), extracellular volume (ECV) on dual-layer spectral-detector CT scoring systems for estimating liver fibrosis (LF) in 45 patients with pathologically staged LF. ECV measured on CT value (HU-ECV), iodine density (ID-ECV), atomic number (Zeff-ECV), and electron density (ED-ECV), LV or SV/body surface area (BSA), albumin bilirubin grade (ALBI), model for end-stage liver disease (MELD) score, aspartate aminotransferase platelet ratio index (APRI), and fibrosis index based on the four factors (FIB-4) were recorded. Transient elastography was measured in 22 patients, and compared to ECV. No correlation was found between transient elastography and all ECVs. Area under the curve (AUC) for estimating F4 on transient elastography was 0.885 (95% CI 0.745-1.000). ALBI was weakly associated with LF (p = 0.451), while MELD (p < 0.001), APRI (p = 0.010), and FIB-4 (p = 0.010) were significantly associated with LF. SV/BSA had a higher AUC than MELD, APRI, and FIB-4 for estimating F4 (AUC = 0.815, 95% CI 0.63-0.999), but MELD (AUC = 0.799, 95% CI 0.634-0.965), APRI (AUC = 0.722, 95% CI 0.561-0.883), and FIB-4 (AUC = 0.741, 95% CI 0.582-0.899) had higher AUCs than ALBI. SV/BSA significantly contributed to differentiation for estimating F4; odds ratio (OR) was 1.304-1.353 (Reader 1-2; R1-R2), whereas MELD significantly contributed to the differentiation between F0-2 and F3-4; OR was 1.528-1.509 (R1-R2). AUC for SV/BSA and MELD combined was 0.877 (95% CI 0.748-1.000). In conclusion, SV/BSA allows for a higher estimation of liver cirrhosis (F4). MELD is more suitable for assessing severe LF (≥ F3-4). The combination of SV/BSA and MELD had a higher AUC than SV/BSA alone for liver cirrhosis (F4).

Treatment response to ursodeoxycholic acid in primary biliary cholangitis: A systematic review and meta-analysis

BACKGROUND

Several ursodeoxycholic acid (UDCA) treatment response definitions have been introduced in primary biliary cholangitis (PBC). However, the lack of a gold standard results in heterogeneity in second-line treatment research and clinical practice.

AIMS

This study aimed to explore which UDCA treatment response endpoint serves as the most accurate predictive model of long-term outcome.

METHODS

A systematic review and meta-analysis of UDCA treatment response endpoints (and corresponding validations) were performed.

RESULTS

Sixteen individual UDCA treatment response endpoints and 96 external validations were found. Barcelona, Paris-1, Paris-2, Rotterdam, Toronto and GLOBE and UK-PBC Risk Scores are currently most robustly validated in external populations. The results show that the continuous models (GLOBE and UK-PBC Risk Scores) serve as the most accurate predictive models. Besides standard UDCA treatment response endpoints, the alkaline phosphatase and total bilirubin normalization has been suggested as a new therapeutic target.

CONCLUSIONS

The GLOBE and UK-PBC Risk Scores are the most suitable for the real-world allocation of second-line therapies (obeticholic acid and fibrates). However, in the wake of the recent findings, alkaline phosphatase and total bilirubin normalization should be the primary outcome in trial research in PBC.

Baseline albumin-bilirubin score: a predictor for HBeAg clearance in patients with chronic hepatitis B after nucleos(t)ide analogue treatment

BACKGROUND

Serum biomarkers for predicting HBeAg clearance in patients with chronic hepatitis B (CHB) virus infection during antiviral therapy remain lacking. This study aimed to investigate baseline albumin-bilirubin (ALBI) score for assessing HBeAg clearance in HBeAg-positive CHB patients treated with nucleos(t)ide analogues (NAs).

METHODS

Six hundred and ninety-nine HBeAg-positive CHB patients treated with first-line NAs were retrospectively included. Kaplan-Meier curves were used to compare the possibility of HBeAg clearance and HBeAg seroconversion in different ALBI groups. Cox regression models were used to identify factors associated with HBeAg clearance and HBeAg seroconversion.

RESULTS

Of the patients, 69.8% were male, with a median age of 36.0 years. 174 (24.9%) patients achieved HBeAg clearance after a median of 92.0 (interquartile range 48.0-134.0) weeks of antiviral treatment and 108 (15.5%) patients achieved HBeAg seroconversion. 74.0% and 26.0% of patients were classified as ALBI grade 1 and ALBI grade 2-3, respectively. ALBI grade 2-3 was identified as an independent predictor of HBeAg clearance (hazard ratio 1.570, 95% confidence interval 1.071-2.301, P  = 0.021). The cumulative incidence of HBeAg clearance and HBeAg seroconversion was significantly higher in ALBI grade 2-3 group than group of ALBI grade 1 ( P  < 0.001). Similar results were observed in different subgroups with different antiviral drugs, cirrhosis status, and ALT levels.

CONCLUSION

Baseline ALBI score may be a valuable indicator for predicting antiviral response in HBeAg-positive CHB patients treated with NAs.

Prognostic scores in primary biliary cholangitis patients with advanced disease

BACKGROUND

Due to the chronic progressive disease characteristics of primary biliary cholangitis (PBC), patients with advanced PBC should not be ignored. Most prognostic score studies have focused on early stage PBC.

AIM

To compare the prognostic value of various risk scores in advanced PBC to help PBC patients obtain more monitoring and assessment.

METHODS

This study considered patients diagnosed with PBC during hospitalization between 2015 and 2021. The clinical stage was primarily middle and late, and patients usually took ursodeoxycholic acid (UDCA) after diagnosis. The discriminatory performance of the scores was assessed with concordance statistics at baseline and after 1 year of UDCA treatment. Telephone follow-up was conducted to analyze the course and disease-associated outcomes. The follow-up deadline was December 31, 2021. We compared the risk score indexes between those patients who reached a composite end point of death or liver transplantation (LT) and those who remained alive at the deadline. The combined performance of prognostic scores in estimating the risk of death or LT after 1 year of UDCA treatment was assessed using Cox regression analyses. Predictive accuracy was evaluated by comparing predicted and actual survival through Kaplan-Meier analyses.

RESULTS

We included 397 patients who were first diagnosed with PBC during hospitalization and received UDCA treatment; most disease stages were advanced. After an average of 6.4 ± 1.4 years of follow-up, 82 patients had died, and 4 patients had undergone LT. After receiving UDCA treatment for 1 year, the score with the best discrimination performance was the Mayo, with a concordance statistic of 0.740 (95% confidence interval: 0.690-0.791). The albumin-bilirubin, GLOBE, and Mayo scores tended to overestimate transplant-free survival. Comparing 7 years of calibration results showed that the Mayo score was the best model.

CONCLUSION

The Mayo, GLOBE, UK-PBC, and ALBI scores demonstrated comparable discriminating performance for advanced stage PBC. The Mayo score showed optimal discriminatory performance and excellent predictive accuracy.

The Albumin-Bilirubin Score as a Predictor of Liver-Related Mortality in Primary Biliary Cholangitis with Compensated Cirrhosis

BACKGROUND

Although several prognostic scores have been reported to correlate with the prognosis of primary biliary cholangitis (PBC) patients, there are limited tools to predict the prognosis of PBC with compensated cirrhosis. This study aimed to evaluate the prognostic performance of the albumin-bilirubin (ALBI) score in PBC patients with compensated cirrhosis.

METHODS

We conducted a retrospective longitudinal study of 219 patients with compensated PBC cirrhosis to evaluate the prognostic performance of the ALBI using Cox regression model, receiver operating characteristic (ROC) curve, and Kaplan-Meier method.

RESULTS

During follow-up, a total of 19 subjects (8.7%) met the primary endpoint of liver-related death or liver transplantation (LT). Patients who died/underwent LT have higher ALBI score (-1.06 vs. -2.06, p < 0.001) at baseline than those who survived. ALBI score (hazard ratio: 15.011, 95% confidence interval [CI]: 5.045-44.665, p < 0.001) was associated with an increase in liver-related mortality or LT. ALBI score had the best discriminative capacity to predict the 5-year liver-related mortality (area under the ROC curve: 0.871, 95% CI [0.820, 0.913]) compared with other prognostic scores. The ROC curve showed that the best cut-off value of ALBI score was -1.47, with 90.0% sensitivity and 76.6% specificity. Also, the probability of transplant-free survival decreased with increasing ALBI grade (log-rank p = 0.003). The 5-year transplant-free survival rates of patients in grade 1, grade 2, and grade 3 were 100.0%, 96.4%, and 89.4%, respectively.

CONCLUSION

ALBI score is a simple and effective predictive factor estimating the clinical outcome of patients with compensated PBC cirrhosis and provides better prognostic performance compared with other prognostic scores.

Prognostic utility of albumin-bilirubin grade in Japanese patients with primary biliary cholangitis

Background & Aims

The albumin-bilirubin (ALBI) score is calculated using serum levels of total bilirubin and albumin as a simple method to assess liver function. This study investigated the ability of baseline ALBI score/grade measurements to assess histological stage and disease progression in individuals with primary biliary cholangitis (PBC) in a large Japanese nationwide cohort.

Methods

A total of 8,768 Japanese patients with PBC were enrolled between 1980 and 2016 from 469 institutions, among whom 83% received ursodeoxycholic acid (UDCA) only, 9% received UDCA and bezafibrate, and 8% were given neither drug. Baseline clinical and laboratory parameters were retrospectively retrieved and reviewed from a central database. Associations of ALBI score/grade with histological stage, mortality, and need for liver transplantation (LT) were evaluated using Cox proportional hazards models.

Results

During the median follow-up period of 5.3 years, 1,227 patients died (including 789 from liver-related causes) and 113 underwent LT. ALBI score and ALBI grade were significantly associated with Scheuer's classification (both p <0.0001). ALBI grade 2 or 3 had significant associations with all-cause mortality or need for LT as well as liver-related mortality or need for LT according to Cox proportional hazards regression analysis (hazard ratio 3.453, 95% CI 2.942-4.052 and hazard ratio 4.242, 95% CI 3.421-5.260, respectively; both p <0.0001). Cumulative LT-free survival rates at 5 years in the ALBI grade 1, 2, and 3 groups were 97.2%, 82.4%, and 38.8%, respectively, while respective non-liver-related survival rates were 98.1%, 86.0%, and 42.0% (both p <0.0001, log-rank test).

Conclusions

This large nationwide study of patients with PBC suggested that baseline measurements of ALBI grade were a simple non-invasive predictor of prognosis in PBC.

Impact and implications

Primary biliary cholangitis (PBC) is an autoimmune liver disease characterized by progressive destruction of intrahepatic bile ducts. This study examined the ability of albumin-bilirubin (ALBI) score/grade to estimate histological findings and disease progression in PBC by means of a large-scale nationwide cohort in Japan. ALBI score/grade were significantly associated with Scheuer's classification stage. Baseline ALBI grade measurements may be a simple non-invasive predictor of prognosis in PBC.

Significance of pretreatment alpha-fetoprotein in patients with compensated severe fibrosis after hepatitis C viral eradication

BACKGROUND

We aimed to investigate the factors associated with improvement of liver functional reserve after sustained virological response using interferon-free, direct-acting antiviral combination treatment in patients with compensated, severe fibrosis.

METHODS

Between September 2014 and April 2020, 492 patients received direct-acting antiviral combination treatment in our hospital. Among them, 173 patients who had severe fibrosis based on a fibrosis-4 index ≥3.25, showed sustained virological response after treatment. We investigated the dynamic change in albumin-bilirubin score and the baseline factors associated with its improvement, 48 weeks after treatment.

RESULTS

The baseline significant factors associated with albumin-bilirubin ≦ -0.5 were lower albumin (HR: 15.625, 95% CI: 4.273-58.824, P < .001), higher hepatitis C virus RNA (HR: 4.995, 95% CI: 1.882-13.260, P = .001), and higher alpha-fetoprotein (HR: 1.033, 95% CI: 1.011-1.055, P = .003). Patients with alpha-fetoprotein ≧10 ng/mL showed significant improvement of albumin-bilirubin score from baseline to 48 weeks after treatment compared to those with alpha-fetoprotein <10 ng/mL (P < .001).

CONCLUSIONS

Baseline serum alpha-fetoprotein might be a predictive factor for improvement of liver function after sustained virological response in patients with severe fibrosis.

Gadoxetic acid-enhanced MRI-derived functional liver imaging score (FLIS) and spleen diameter predict outcomes in ACLD

BACKGROUND & AIMS

Functional liver imaging score (FLIS) - derived from gadoxetic acid-enhanced MRI - correlates with liver function and independently predicts liver-related mortality in patients with chronic liver disease (CLD), while splenic craniocaudal diameter (SCCD) is a marker of portal hypertension. The aim of this study was to investigate the accuracy of a combination of FLIS and SCCD for predicting hepatic decompensation, acute-on-chronic liver failure (ACLF), and mortality in patients with advanced CLD (ACLD).

METHODS

We included 397 patients with CLD who underwent gadoxetic acid-enhanced liver MRI. The FLIS was calculated by summing the points (0-2) of 3 hepatobiliary-phase features: hepatic enhancement, biliary excretion, and portal vein signal intensity. Patients were stratified into 3 groups according to liver fibrosis severity and presence/history of hepatic decompensation: non-ACLD, compensated ACLD (cACLD), and decompensated ACLD (dACLD).

RESULTS

SCCD showed excellent intra- and inter-reader agreement. Importantly, SCCD was an independent risk factor for hepatic decompensation in patients with cACLD (per cm; adjusted hazard ratio [aHR] 1.13; 95% CI 1.04-1.23; p = 0.004). Patients with cACLD and a FLIS of 0-3 points and/or a SCCD of >13 cm were at increased risk of hepatic decompensation (aHR 3.07; 95% CI 1.43-6.59; p = 0.004). In patients with dACLD, a FLIS of 0-3 was independently associated with an increased risk of ACLF (aHR 2.81; 95% CI 1.16-6.84; p = 0.02), even after adjusting for other prognostic factors. Finally, a FLIS and SCCD-based algorithm was independently predictive of transplant-free mortality and stratified the probability of transplant-free survival (TFS) in ACLD (p <0.001): FLIS 4-6 and SCCD ≤13 cm (5-year TFS of 84%) vs. FLIS 4-6 and SCCD >13 cm (5-year TFS of 70%) vs. FLIS 0-3 (5-year TFS of 24%).

CONCLUSION

The FLIS and SCCD are simple imaging markers that provide complementary information for risk stratification in patients with compensated and decompensated ACLD.

LAY SUMMARY

Magnetic resonance imaging (MRI) can be used to assess the state of the liver. Previously the functional liver imaging score, which is based on MRI criteria, was developed as a measure of liver function and to predict the risk of liver-related complications or death. By combining this score with a measurement of spleen diameter, also using MRI, we generated an algorithm that could predict the risk of adverse liver-related outcomes in patients with advanced chronic liver disease.

The ALBI score: From liver function in patients with HCC to a general measure of liver function

The (albumin-bilirubin) ‘ALBI’ score is an index of ‘liver function’ that was recently developed to assess prognosis in patients with hepatocellular carcinoma, irrespective of the degree of underlying liver fibrosis. Other measures of liver function, such as model for end-stage liver disease (MELD) and Child-Pugh score, which were introduced for specific clinical scenarios, have seen their use extended to other areas of hepatology. In the case of ALBI, its application has been increasingly extended to chronic liver disease in general and in some instances to non-liver diseases where it has proven remarkably accurate in terms of prognosis. With respect to chronic liver disease, numerous publications have shown that ALBI is highly prognostic in patients with all types and stages of chronic liver disease. Outside of liver disease, ALBI has been reported as being of prognostic value in conditions ranging from chronic heart failure to brain tumours. Whilst in several of these reports, explanations for the relationship of liver function to a clinical condition have been proposed, it has to be acknowledged that the specificity of ALBI for liver function has not been clearly demonstrated. Nonetheless, and similar to the MELD and Child-Pugh scores, the lack of any mechanistic basis for ALBI’s clinical utility does not preclude it from being clinically useful in certain situations. Why albumin and bilirubin levels, or a combination thereof, are prognostic in so many different diseases should be studied in the future.

Determination of hepatic extraction fraction with gadoxetate low‐temporal resolution DCE‐MRI ‐based deconvolution analysis: validation with ALBI score and Child‐Pugh class

INTRODUCTION

In this study, we aimed to investigate the feasibility of gadoxetate low-temporal resolution (LTR) DCE-MRI for voxel-based hepatic extraction fraction (HEF) quantification for liver sparing radiotherapy using a deconvolution analysis (DA) method.

METHODS

The accuracy and consistency of the deconvolution implementation in estimating liver function was first assessed using simulation data. Then, the method was applied to DCE-MRI data collected retrospectively from 64 patients (25 normal liver function and 39 cirrhotic patients) to generate HEF maps. The normal liver function patient data were used to measure the variability of liver function quantification. Next, a correlation between HEF and ALBI score (a new model for assessing the severity of liver dysfunction) was assessed using Pearson's correlation. Differences in HEF between Child-Pugh score classifications were assessed for significance using the Kruskal-Wallis test for all patient groups and Mann-Whitney U-test for inter-groups. A statistical significance was considered at a P-value <0.05 in all tests.

RESULTS

The results showed that the implemented method accurately reproduced simulated liver function; root-mean-square error between estimated and simulated liver response functions was 0.003, and the coefficient-of-variance of HEF was <20%. HEF correlation with ALBI score was r = -0.517, P < 0.0001, and HEF was significantly decreased in the cirrhotic patients compared to normal patients (P < 0.0001). Also, HEF in Child-Pugh B/C was significantly lower than in Child-Pugh A (P = 0.024).

CONCLUSION

The study demonstrated the feasibility of gadoxetate LTR-DCE MRI for voxel-based liver function quantification using DA. HEF could distinguish between different grades of liver function impairment and could potentially be used for functional guidance in radiotherapy.

Preoperative albumin-bilirubin score as a prognostic indicator in patients with stage III colon cancer

The albumin-bilirubin (ALBI) score was created to assess the severity of liver dysfunction and to predict prognosis of hepatocellular carcinoma. Purpose of this study was to investigate the prognostic value of the ALBI score in patients with stage III colon cancer using propensity score matching (PSM) analysis. This study analyzed 510 patients with stage III colon cancer who had surgery between 2014 and 2015. The ALBI score was calculated as follows: (log10 bilirubin (μmol/L) [Formula: see text] 0.66) + (albumin (g/L) [Formula: see text] -0.0852), and the optimal cut-off value was determined using a receiver operating characteristic analysis and the Youden Index. According to the calculated cut-off value, patients were divided into two groups: Group A (ALBI ≤  - 2.54) and Group B (ALBI >  - 2.54). The average ALBI score was - 2.68 (from - 3.39 to - 0.69). Group A had a significantly higher 5-year disease-free survival rate (85.5% vs 75.7%, p = 0.02), 5-year cancer-specific survival rate (93.7% vs 84.4%, p = 0.02), and 5-year overall survival rate (90.6% vs 77.4%, p = 0.01) than Group B. High ALBI scores were found to be an independent risk factor for both disease-free survival (HR 1.68, p = 0.048) and cancer-specific survival (HR 2.24, p = 0.028). The preoperative ALBI score was found to be a promising prognostic indicator for predicting recurrence and survival in patients with stage III colon cancer in this study. Because the ALBI score is simple and inexpensive to obtain, it has the potential to be a useful clinical marker for colon cancer patients.

Pretransplant Evaluation and Liver Transplantation Outcome in PBC Patients

Primary biliary cholangitis (PBC) is an autoimmune chronic cholestatic liver disease characterized by progressive cholangiocyte and bile duct destruction leading to fibrosis and finally to liver cirrhosis. The presence of disease-specific serological antimitochondrial antibody (AMA) together with elevated alkaline phosphatase (ALP) as a biomarker of cholestasis is sufficient for diagnosis. Ursodeoxycholic acid (UDCA) is the first treatment option for PBC. Up to 40% of patients have an incomplete response to therapy, and over time disease progresses to liver cirrhosis. Several risk scores are proposed for better evaluation of patients before and during treatment to stratify patients at increased risk of disease progression. GLOBE score and UK PBC risk score are used for the evaluation of UDCA treatment and Mayo risk score for transplant-free survival. Liver transplantation (LT) is the only treatment option for end-stage liver disease. More than 10 years after LT, 40% of patients experience recurrence of the disease. A liver biopsy is required to establish rPBC (recurrent primary biliary cholangitis). The only treatment option for rPBC is UDCA, and data show biochemical and clinical improvement, plus potential beneficial effects for use after transplantation for the prevention of rPBC development. Additional studies are required to assess the full impact of rPBC on graft and recipient survival and for treatment options for rPBC.

Analysis of the albumin‐bilirubin score as an indicator of improved liver function among hepatitis C virus patients with sustained viral response after direct‐acting antiviral therapy

Background and Aim

To investigate the performance of the albumin‐bilirubin (ALBI) score as an indicator of improved hepatic function using a cohort of hepatitis C virus (HCV) patients with sustained viral response (SVR) after direct‐acting antiviral therapy (DAA).

Methods

HCV patients who achieved SVR after DAAs between 2015 and 2016 were followed for at least 24 months. Changes in ALBI were evaluated in the entire cohort and according to liver function and liver stiffness status at baseline.

Results

Four hundred ninety‐seven patients were enrolled. Exactly 96.92% were in Child–Pugh (CTP) class A, and 42% had grade 2 fibrosis. Median ALBI was −3.02, while 87.7 and 11.3% of patients were in ALBI grades 1 and 2, respectively. ALBI improved significantly over time, particularly in patients who had a worse ALBI at baseline. Exactly 77% of patients initially in ALBI grade 1 and 93.9% of those in ALBI grades 2–3 improved their ALBI score in different amounts. Improved ALBI was observed irrespective of CTP score at baseline. Median ALBI at baseline and after 24 months were −3.03 and −3.27 for CTP 5, 2.02 and −2.88 for CTP 6, and −1.59 and −2.84 for CTP >6. Similarly, a significant improvement in ALBI was observed within each stage of fibrosis at baseline.

Conclusion

ALBI was a good indicator of improved hepatic function in HCV patients with SVR after DAA therapy, able to identify changes even in those patients who started DAA therapy with well‐preserved function and mild fibrosis. This simple, objective, and noninvasive test should be evaluated in other clinical scenarios where liver function is relevant.

Determining the efficacy of functional liver imaging score (FLIS) obtained from gadoxetic acid-enhanced MRI in patients with chronic liver disease and liver cirrhosis: the relationship between Albumin-Bilirubin (ALBI) grade and FLIS

PURPOSE

(1) To evaluate the efficacy of functional liver imaging score (FLIS) in predicting liver function on gadoxetic acid-enhanced MRI in patients with chronic liver disease (CLD) or liver cirrhosis (LC) and its relationship with ALBI grade. (2) To assess the intra-reader reliability and interreader agreement of readers with different levels of experience in abdominal imaging of FLIS.

METHODS

We retrospectively included 131 patients (70 men, 61 women; mean ± SD, 53.7 ± 14.6 years) with CLD and LC who underwent GA-enhanced MRI between November 2019 and March 2022. FLIS was assigned as a result of the sum of three hepatobiliary phase (HBP) images features, each scored 0-2: liver parenchymal enhancement, biliary contrast excretion, and portal vein sign. FLIS was calculated using HPB images independently by three radiologists with different experience. In addition, 50 randomly selected patients were reviewed a second time by a reader to assess intra-reader reliability. Patients were divided into the following three groups according to the albumin-bilirubin (ALBI) grade: ALBI grade 1, 2, and 3. We evaluated the correlation between ALBI grade and both FLIS and its parameters using Spearman's rank correlation for each reader. Receiver operating characteristic (ROC) curve analysis was performed to show the optimal cut-off value of FLIS to distinguish between ALBI grades. Intra-reader reliability and inter-reader agreement were evaluated by intraclass correlation coefficient (ICC).

RESULTS

FLIS and three FLIS parameters showed very strong correlation with ALBI grade for each readers (r =  - 0.843 to 0.976, - 0.831 to 0.962, and - 0.819 to 0.902, respectively). ROC curve analysis showed that FLIS ≥ 5 was the optimal cutoff for prediction of ALBI grade 1 for each readers (sensitivity, 83.7% to 95.4%; specificity, 82.6% to 87%; accuracy, 88.6% to 93.6% and area under the curve (AUC), 0.882 to 0.917), and FLIS ≤ 3 was the optimal cutoff for distinguish ALBI grade 3 from other grades for each readers (sensitivity, 100%; specificity, 95.2% to 96%; accuracy, 95.4% to 96.2% and AUC, 0.974 to 0.994). Intra-reader reliability (ICC = 0.95; 95% CI 0.93-0.96) and inter-reader agreement (ICC = 0.85 to 0.90; 95% CI 0.82-0.97) for FLIS were excellent.

CONCLUSION

FLIS showed a very correlation with hepatic function level and can stratify the ALBI grades. This feature has demonstrated the potential of FLIS to be excellent radiological tools for predicting of liver function of CLD and LC patients in clinical practice. Also, the excellent agreement of FLIS among readers with different levels of experience indicates that it can be used with high accuracy and reproducibility regardless of experience.

Prognostic Value of a Modified Albumin-Bilirubin Score Designed for Patients with Esophageal Squamous Cell Carcinoma After Radical Resection

BACKGROUND

The albumin-bilirubin (ALBI) score was originally developed to assess the severity of liver dysfunction in patients with hepatocellular carcinoma and has subsequently been used as a prognostic marker for that disease. Here, we examined the value of the preoperative ALBI score as a prognostic marker for patients with esophageal squamous cell carcinoma (ESCC) after radical esophagectomy.

METHODS

We retrospectively analyzed data from 449 patients who underwent curative resection for ESCC. The ALBI score was calculated as (log₁₀ serum bilirubin [μmol/l] × 0.66) + (serum albumin [g/l] × - 0.0852). Receiver operating characteristic curve analysis was used to define a preoperative modified ALBI (mALBI) score for patient stratification.

RESULTS

Of the 449 ESCC patients, 232 and 217 were assigned to mALBI Grade 1 or Grade 2 groups based on preoperative ALBI scores of ≤ - 3.33 or > - 3.33, respectively. Preoperative mALBI grade was significantly associated with age, excessive alcohol consumption, squamous cell carcinoma antigen level, and clinical disease stage. The mALBI Grade 2 group had significantly shorter disease-specific and recurrence-free survival than the mALBI Grade 1 group. Multivariate analysis demonstrated that mALBI Grade 2 was an independent prognostic factor for disease-specific survival (hazard ratio 1.86, 95% confidence interval 1.18-2.93, P = 0.0074). In most subgroup analyses, mALBI Grade 2 was associated with a greater risk of disease-specific death.

CONCLUSIONS

mALBI grade serves as a simple and useful prognostic marker for disease-specific survival in patients with ESCC after radical esophagectomy.

Association of Albumin-Bilirubin Grade and Myosteatosis with its Prognostic Significance for Patients with Colorectal Cancer

BACKGROUND

The albumin-bilirubin (ALBI) grade is a useful prognostic and predictive marker for patients with liver disease. Its clinical significance has been limited to patients with colorectal cancer (CRC). Furthermore, the association between the ALBI grade and skeletal muscle-related indices is unclear.

METHODS

This study enrolled 1015 patients who underwent computed tomography (CT) scans within 31 days before surgery. The prognostic value of the ALBI grade in predicting overall survival (OS) was assessed using the Cox proportional hazards model. The correlation between the ALBI grade and the skeletal muscle index or radiodensity (myosteatosis) was evaluated. The predictive accuracy of ALBI alone and in combination with myosteatosis was compared using Harrell's concordance index (C-index).

RESULTS

The significant prognostic factors for OS identified in the multivariable analysis were the ALBI group (low vs high: hazard ratio [HR], 1.566; 95 % confidence interval [CI], 1.174-2.089; p = 0.002) and myosteatosis (low vs. high: HR, 0.648; 95 % CI, 0.486-0.865; p = 0.003). The rate of low-grade myosteatosis increased as the ALBI grade increased. The C-index of combined ALBI and myosteatosis (0.650; 95 % CI, 0.618-0.683) was superior to that of ALBI alone (0.603; 95 % CI, 0.575-0.631; bootstrap incremental area under the curve [iAUC] mean difference, 0.047; 95 % CI, 0.012-0.070) and myosteatosis alone (0.608; 95 % CI, 0.577-0.640; bootstrap iAUC mean difference, 0.042; 95 % CI, 0.023-0.064).

CONCLUSION

The ALBI grade is significantly associated with myosteatosis. The ALBI grade is a significant prognostic factor, and the combination of ALBI and myosteatosis show an additive value in discriminating survival of patients with CRC.

Prognosis of patients with liver cirrhosis: A multi-center retrospective observational study

AIM

Despite advances in the management of liver diseases and changes in the etiology of cirrhosis, few studies have updated the prognosis of cirrhosis. This study aimed to clarify the recent prognosis of cirrhosis and identify risk factors for death.

METHODS

In this retrospective observational study by the Hepatic Disease Network of the National Hospital Organization in Japan, chart reviews were performed to follow patients with cirrhosis beginning in 2011. We conducted Kaplan-Meier survival time analyses stratified by Child-Pugh classification and albumin-bilirubin grade. Cox regression analysis was used to identify risk factors for death.

RESULTS

We identified 444 eligible patients from 25 hospitals, including 303 (68%), 110 (25%), and 31 (7%) patients with Child-Pugh classes A, B, and C, respectively. Hepatitis C virus infection was the cause of cirrhosis for 63% of the patients. The 1-year and 5-year cumulative survival rates of patients with Child-Pugh classes A, B, and C were 90% and 61%, 78% and 42%, and 65% and 25%, respectively. The 1-year and 5-year cumulative survival rates of patients with albumin-bilirubin grades 1, 2, and 3 were 98% and 80%, 91% and 56%, and 58% and 23%, respectively. Cirrhosis classification (Child-Pugh and albumin-bilirubin), age, liver cancer, and untreated esophageal varices were associated with increased hazard of death.

CONCLUSIONS

Little improvement was observed in the prognosis of cirrhosis compared with previous reports, and the prognosis of Child-Pugh class C cirrhosis remained poor. Untreated esophageal varices were identified as a risk factor for death.

Soluble CD163 Is a Predictor of Mortality in Patients With Decompensated Cirrhosis

Background: Soluble CD163 (sCD163) is a scavenger receptor membrane protein expressed almost exclusively on Kupffer cells and other macrophages. It was found to be associated with the severity of liver cirrhosis. The aim of the present study was to determine whether the novel biomarker sCD163 predicts outcomes in patients with decompensated cirrhosis. Materials and Methods: A single-center, observational, prospective study with 345 decompensated cirrhosis patients was conducted in the Gastroenterology Department between January 2017 and December 2020. Their plasma samples were tested by enzyme-linked immunosorbent assay (ELISA) for sCD163 within 24 hours of admission. These patients were followed up at 28 days, 3 months and 6 months. The independent risk factors were identified with uni- and multivariate logistic regression analyses. We evaluated the predictive performance of the new scoring system (including sCD163) and the original scoring system. Results: The sCD163 level was significantly higher in non-surviving patients than in surviving patients. Positive associations were found between sCD163 levels and the Child-Turcotte-Pugh (CTP), Model for End-Stage Liver Disease (MELD) and albumin-bilirubin (ALBI) scores. Logistic regression confirmed that sCD163 was an independent risk factor for 28-day, 3-month, and 6-month mortality. The areas under the receiver operating characteristic curves (AUROCs) of the use of sCD163 for the prediction of 28-day, 3-month, and 6-month mortality were relatively higher (AUROCs: 0.856; 0.823 and 0.811, respectively). The AUROCs of the new scores obtained by adding sCD163 to the original scoring systems (CTP + sCD163, MELD + sCD163 and ALBI + sCD163) showed that the new scoring systems had better predictive performance than the original scoring systems at all time points (P < 0.001). Conclusion: sCD163 is a prognostic predictor of short-term and long-term outcomes in decompensated cirrhosis patients. Accordingly, the addition of sCD163 to the original clinical scoring systems improved their prognostic performance.

A Nomogram Based on Preoperative Inflammatory Indices and ICG-R15 for Prediction of Liver Failure After Hepatectomy in HCC Patients

Objective

To establish a nomogram based on inflammatory indices and ICG-R15 for predicting post-hepatectomy liver failure (PHLF) among patients with resectable hepatocellular carcinoma (HCC).

Methods

A retrospective cohort of 407 patients with HCC hospitalized at Xiangya Hospital of Central South University between January 2015 and December 2020, and 81 patients with HCC hospitalized at the Second Xiangya Hospital of Central South University between January 2019 and January 2020 were included in the study. Totally 488 HCC patients were divided into the training cohort (n=378) and the validation cohort (n=110) by random sampling. Univariate and multivariate analysis was performed to identify the independent risk factors. Through combining these independent risk factors, a nomogram was established for the prediction of PHLF. The accuracy of the nomogram was evaluated and compared with traditional models, like CP score (Child-Pugh), MELD score (Model of End-Stage Liver Disease), and ALBI score (albumin-bilirubin) by using receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis (DCA).

Results

Cirrhosis (OR=2.203, 95%CI:1.070-3.824, P=0.030), prothrombin time (PT) (OR=1.886, 95%CI: 1.107-3.211, P=0.020), tumor size (OR=1.107, 95%CI: 1.022-1.200, P=0.013), ICG-R15% (OR=1.141, 95%CI: 1.070-1.216, P<0.001), blood loss (OR=2.415, 95%CI: 1.306-4.468, P=0.005) and AST-to-platelet ratio index (APRI) (OR=4.652, 95%CI: 1.432-15.112, P=0.011) were independent risk factors of PHLF. Nomogram was built with well-fitted calibration curves on the of these 6 factors. Comparing with CP score (C-index=0.582, 95%CI, 0.523-0.640), ALBI score (C-index=0.670, 95%CI, 0.615-0.725) and MELD score (C-ibasedndex=0.661, 95%CI, 0.606-0.716), the nomogram showed a better predictive value, with a C-index of 0.845 (95%CI, 0.806-0.884). The results were consistent in the validation cohort. DCA confirmed the conclusion as well.

Conclusion

A novel nomogram was established to predict PHLF in HCC patients. The nomogram showed a strong predictive efficiency and would be a convenient tool for us to facilitate clinical decisions.

Efficacy of albumin-bilirubin score to predict hepatic encephalopathy in patients underwent transjugular intrahepatic portosystemic shunt

BACKGROUND AND AIMS

The occurrence of hepatic encephalopathy is one of the main factors limiting the development and application of transjugular intrahepatic portosystemic shunt (TIPS). Our study aimed to verify the efficacy of the albumin-bilirubin score, an objective and simple scoring system, to predict post-TIPS hepatic encephalopathy.

METHODS

From February 2014 to July 2019, a total of 224 patients who underwent TIPS procedure were entered into the study. All patients were followed up after TIPS placement. Relevant clinical data within 24 h after admission were collected to compare the differences between patients with and without hepatic encephalopathy after TIPS placement.

RESULTS

A total of 82 (36.6%) patients developed post-TIPS hepatic encephalopathy. Age and albumin-bilirubin score was found to be independent risk factors for post-TIPS hepatic encephalopathy. The albumin-bilirubin score shows a good ability to predict the occurrence of hepatic encephalopathy within 1 year after TIPS. The area under the receiver operating characteristic curve is 0.74 (95% confidence interval: 0.673-0.806). In addition, in order to improve its feasibility, we regrouped the albumin-bilirubin score into three levels (albumin-bilirubin≤ -1.95, low risk; 1.95 <albumin-bilirubin ≤1.45, intermediate risk; albumin-bilirubin > -1.45, high risk).

CONCLUSION

The albumin-bilirubin score has a good predictive value for the possibility of post-TIPS hepatic encephalopathy, which is better than the model for end-stage liver disease and Child-Pugh score.

Predictive Model of Ursodeoxycholic Acid Treatment Response in Primary Biliary Cholangitis

BACKGROUND AND AIMS

Although ursodeoxycholic acid (UDCA) treatment in primary biliary cholangitis is effective in many patients, there are still many people who respond poorly to it. Identifying and intervening these patients early is important. Therefore, exploring the risk factors and proposing a predictor index to predict the UDCA treatment nonresponse earlier among primary biliary cholangitis patients were the aims of this research.

METHODS

A total of 135 primary biliary cholangitis patients treated with UDCA (13-15 mg/kg/d) were enrolled in this retrospective study. The response to treatment was evaluated based on Paris I criteria. The univariate and logistic multivariate regression analyses were adopted to determine the independent risk factors and propose a predictor index. Receiver operating characteristic curve was used to evaluate the predictive ability of the predictor index.

RESULTS

Total bilirubin, albumin, globulin, immunoglobin M, and aspartate aminotransferase-to-platelet ratio index were the five independent risk factors associating with early biochemical nonresponse to UDCA treatment. Based on these factors, we established a predictor index with the predictive value being 0.886 (sensitivity: 82.80%, specificity: 84.40%).

CONCLUSIONS

We developed a predictor index that had an accurate prediction of the early biochemical nonresponse to UDCA treatment, which is expected to provide valuable information for the high-risk group before treatment begins.

Effectiveness of Albumin-bilirubin Score as a Predictor of Post-hepatectomy Liver Failure in Patients with Hepatocellular Carcinoma

Backgrounds/Aims

Post-hepatectomy liver failure (PHLF) is a major concern for patients with hepatocellular carcinoma (HCC) who have undergone liver resection. The albumin-bilirubin (ALBI) score is a novel model for assessing liver function. We aimed to investigate the effectiveness of the ALBI score as a predictor of PHLF in HCC patients who have undergone hepatectomy in South Korea.

Methods

Between January 2014 and November 2018, HCC patients who underwent hepatectomy and indocyanine retention rate at 15 min (ICG-R15) test were enrolled in this study.

Results

A total of 101 patients diagnosed with HCC underwent hepatectomy. Thirty-two patients (31.7%) experienced PHLF. The ALBI score (OR 2.83; 95% CI 1.22-6.55; p=0.015), ICG-R15 (OR 1.07; 95% CI 1.02-1.12; p=0.007) and ALBI grade (OR 2,86; 95% CI 1.08-7.58; p=0.035) were identified as independent predictors of PHLF by multivariable analysis. The area under the receiver operating characteristic curve of the ALBI score and ICG-R15 were 0.676 (95% CI 0.566-0.785) and 0.632 (95% CI 0.513-0.752), respectively. The optimal cutoff value of the ALBI score in predicting PHLF was -2.62, with a sensitivity of 75.0% and a specificity of 56.5%.

Conclusions

The ALBI score is an effective predictor of PHLF in patients with HCC, and its predictive ability is comparable to that of ICG-R15.

Preoperative Predictors for 90-Day Mortality after Pancreaticoduodenectomy in Patients with Adenocarcinoma of the Ampulla of Vater: A Single-Centre Retrospective Cohort Study

Background

The standard treatment for ampullary adenocarcinoma is pancreaticoduodenectomy. Identification of preoperative risk factors might help the clinician to select patients fit for resection and potentially decrease morbidity and mortality after PD. We conducted a cohort study to determine the preoperative factors related to 90-day severe morbidity and mortality after PD.

Methods

We conducted a retrospective cohort study in patients with a diagnosis of ampullary adenocarcinoma who underwent an open PD between January 2010 and December 2019 at our tertiary centre.

Results

Independent preoperative predictors of mortality were the albumin-bilirubin (ALBI) grade 3 (OR: 21.7; CI 95: 2.1–226.9; p=0.01) and the estimated glomerular filtration rate (eGFR) <90 mL/min/1.73 m² (OR: 17.7; CI 95: 1.8–172.6; p=0.013). The eGFR <90 mL/min/1.73 m² (OR = 6.6; CI 95: 1.9–23.4; p=0.003) and prothrombin time (OR = 1.5; CI 95; 1.1–2.1; p=0.005) were independent predictors for severe morbidity.

Conclusion

These findings suggest that baseline renal function measured by the eGFR and liver function categorized with the ALBI grading are predictors of severe morbidity and mortality. Thus, they should be considered when selecting patients for PD or the use of neoadjuvant treatments. Further research is warranted.

Liver stiffness measurement predicts short-term and long-term outcomes in patients with hepatocellular carcinoma after curative liver resection

BACKGROUND AND AIM

Hepatocellular carcinoma is one of the commonest cancer in the world. Despite curative resection, recurrence remains the largest challenge. Many risk factors were identified for predicting recurrence, including liver fibrosis and cirrhosis. Transient elastography (Fibroscan) is an accurate tool in measuring liver fibrosis. This study aimed to evaluate the use of preoperative liver stiffness measurement (LSM), with Fibroscan in predicting long-term recurrence of hepatocellular carcinoma (HCC) after curative resection.

METHOD

A prospective cohort study was conducted from February 2010 - June 2017 in Prince of Wales hospital. All consecutive patients with HCC undergone hepatectomy were included. Demographic factors, preoperative LSM, tumor characteristics and operative details were assessed. Primary outcome and secondary outcome were overall survival and disease free survival at 1 year, 3 year and 5 year respectively.

RESULTS

A total of 401 cases were included. Patients with LSM ≥12kPa had significantly lower 5-year overall survival rate (75.1% vs 57.3%, p < 0.001) and disease free survival rate (45.8% vs. 26.7%, p < 0.001). On multivariate analysis, pre-operative creatinine and vascular invasion of tumor were significant factors in predicting early recurrence (p = 0.012 and p = 0.004). LSM ≥12kPa were the only significant factor in predicting late recurrence (p = 0.048).

CONCLUSION

Pre-operative liver stiffness measurement could predict the late recurrence of hepatocellular carcinoma after curative resection.

Clinical Significance of Preoperative Albumin-Bilirubin Grade in Pancreatic Cancer

BACKGROUND

No study has clarified the clinical significance of albumin-bilirubin (ALBI) grade in a large cohort of pancreatic cancer patients.

METHODS

A total of 1006 consecutive patients diagnosed with pancreatic cancer and deemed eligible for surgical resection were analyzed. The ALBI score was calculated as: ALBI score = (log₁₀ bilirubin [µmol/L] × 0.66) + (albumin [g/L]  × - 0.0852). ALBI grade was assigned as grade 1, 2a, 2b, and 3. ALBI grade 1 was assigned to the ALBI low group (N = 566), and grades 2a, 2b, and 3 to the ALBI high group (N = 440).

RESULTS

The primary lesion could not be resected in 129 patients. Among all patients, overall survival (OS) was significantly worse in the ALBI high group than in the ALBI low group (P = 0.024). Overall, 877 patients underwent pancreatectomy. In these patients, the ALBI high group was associated with high CA19-9 level (P < 0.001), lower morbidity rate (P < 0.001), and pancreatic head tumor (P = 0.001). Patients' OS after resection was significantly worse in the ALBI high group than in the ALBI low group (P < 0.001). Cox proportional hazard analysis revealed ALBI grade as an independent predictor for prognosis (hazard ratio, 1.33; P = 0.015). Even in the CA19-9 negative patients, OS was significantly worse in the ALBI high group than in the ALBI low group (P = 0.046).

CONCLUSIONS

The ALBI grade is a clinically useful predictor for prognosis in pancreatic cancer patients.

Assessing the Prediction Effect of Various Prognosis Model for 28-Day Mortality in Acute-on-Chronic Liver Failure Patients

Background

Acute-on-chronic liver failure (ACLF) is an extremely clinical entity associated with short-term high mortality. The CLIF-SOFA score measures both hepatic and extrahepatic organ dysfunction and can discriminate significantly better between survivors and nonsurvivors compared to other methods. The MELD score is widely used for organ allocation in liver transplantation. Recent reports indicate that the PWR is a potential biomarker for predicting clinical outcomes. The ALBI score is a new score model for evaluating the severity of liver dysfunction. We aimed to compare these prognosis models to predict short-term mortality in ACLF patients.

Methods

A retrospective analysis of 89 ACLF patients between 2015 and 2018 was performed. The receiver operating characteristic (ROC) curve was used to assess the power of four prognosis models for predicting 28-day mortality in patients with ACLF.

Results

The ALBI score, MELD score and CLIF-SOFA score were significantly higher, and the PWR was slightly lower in nonsurviving ACLF patients than in surviving patients. The MELD score and ALBI score were positively correlated with the CLIF-SOFA score, while the PWR was inversely related to the CLIF-SOFA score. The area under the ROC curves (AUROCS) of the CLIF-SOFA score, PWR, ALBI score and MELD score were 0.804, 0.759, 0.710 and 0.670, respectively.

Conclusion

The CLIF-SOFA score, PWR and ALBI score can better predict 28-day mortality in ACLF patients, but the MELD score has worse predictability. The CLIF-SOFA score is the best prognosis model among these models. PWR may be a simple and useful tool that can predict 28-day outcome.

Predicting Operative Outcomes in Patients with Liver Disease: Albumin-Bilirubin Score vs Model for End-Stage Liver Disease-Sodium Score

BACKGROUND

The albumin-bilirubin score (ALBI) has recently been shown to have increased accuracy in predicting post-hepatectomy liver failure and mortality compared with the Model for End-Stage Liver Disease (MELD). However, the use of ALBI as a predictor of postoperative mortality for other surgical procedures has not been analyzed. The aim of this study was to measure the predictive power of ALBI compared with MELD-sodium (MELD-Na) across a wide range of surgical procedures.

STUDY DESIGN

Patients undergoing cardiac, pulmonary, esophageal, gastric, gallbladder, pancreatic, splenic, appendix, colorectal, adrenal, renal, hernia, and aortic operations were identified in the 2015-2018 American College of Surgeons NSQIP database. Patients with missing laboratory data were excluded. Univariable analysis and receiver operator characteristic curves were performed for 30-day mortality and morbidity. Areas under the curves were calculated to validate and compare the predictive abilities of ALBI and MELD-Na.

RESULTS

Of 258,658 patients, the distribution of ALBI grades 1, 2, 3 were 51%, 42%, and 7%, respectively. Median MELD-Na was 7.50 (interquartile range 6.43 to 9.43). Overall 30-day mortality rate was 2.7% and overall morbidity was 28.6%. Increasing ALBI grade was significantly associated with mortality (ALBI grade 2: odds ratio [OR] 5.24; p < 0.001; ALBI grade 3: OR 25.6; p < 0.001) and morbidity (ALBI grade 2: OR 2.15; p < 0.001; ALBI grade 3: OR 6.12; p < 0.001). On receiver operator characteristic analysis, ALBI outperformed MELD-Na with increased accuracy in several operations.

CONCLUSIONS

ALBI score predicts mortality and morbidity across a wide spectrum of surgical procedures. When compared with MELD-Na, ALBI more accurately predicts outcomes in patients undergoing pulmonary, elective colorectal, and adrenal operations.

Early echocardiographic signs of diastolic dysfunction predict acute kidney injury in cirrhotic patients

BACKGROUND

Cardiovascular dysfunction in cirrhotic patients affects survival and the development of cirrhotic complications. We aimed to evaluate potential echocardiographic parameters to predict mortality and acute kidney injury (AKI) in cirrhotic patients.

METHODS

A total of 103 cirrhotic patients who underwent echocardiography between February 2009 and August 2016 in Taipei Veterans General Hospital were retrospectively enrolled. Cardiac function was evaluated using transthoracic two-dimensional echocardiography with tissue Doppler imaging. Cox hazard regression analysis was used for assessing predictors for 1-year mortality and AKI within 1 year.

RESULTS

Baseline echocardiographic parameters were similar between survivors (n = 92) and nonsurvivors (n = 11). Lower serum levels of albumin, as well as higher albumin-bilirubin (ALBI) scores, Child-Pugh scores, and model for end-stage liver disease scores were observed in nonsurvivors. Cox proportional hazard regression analysis revealed Child-Pugh score as the only predictor of 1-year mortality. Baseline serum creatinine (Cr) > 1.5 mg/dL, total bilirubin > 2 mg/dL, and a higher E/e' ratio predict occurrence of AKI within 1 year. Among patients with serum Cr < 1.5 mg/dL, an increased atrial filling velocity and higher ALBI scores predict AKI occurrence within 1 year.

CONCLUSION

Severity of underlying liver disease but not echocardiographic parameters predicts 1-year mortality in cirrhosis. Early echocardiographic signs of diastolic dysfunction and higher ALBI scores may predict development of AKI in cirrhotic patients with serum Cr < 1.5 mg/dL.

The albumin-bilirubin score as a predictor of outcomes in Japanese patients with PBC: an analysis using time-dependent ROC

The albumin-bilirubin (ALBI) score is calculated using only serum albumin and bilirubin levels, and was developed as a simple method to assess hepatic function. In this study, a total of 409 patients with primary biliary cholangitis (PBC) were enrolled between March 1990 and October 2018. The predictive performances of the ALBI score and other well-established prognostic scores were compared using time-dependent receiver operating characteristic (ROC) analysis. During the follow-up period, 60 patients died, 45 due to liver-related diseases and 15 due to non-liver-related diseases, and 16 patients underwent liver transplantation. Time-dependent ROC analysis showed that the ALBI score has higher the areas under the ROC curves (AUROCs) than the Child-Pugh (C-P) score at each time point; AUROCs at 3, 5, and 10 years after the start of follow-up were 0.94, 0.91, and 0.90 for the ALBI score, and 0.89, 0.88, and 0.82 for the C-P score, respectively. The ALBI score showed the highest AUROCs within 2 years after the start of observation; beyond 2 years, however, the Mayo score had better prognostic ability for mortality and liver transplantation. The ALBI score/grade, derived from objective blood tests, and the Mayo score were superior prognostic tools in PBC patients.

Review of Serum Biomarkers and Models Derived from Them in HBV-Related Liver Diseases

A series of predictive scoring systems is available for stratifying the severity of conditions and assessing the prognosis in patients with HBV-related liver diseases. We show nine of the most popular serum biomarkers and their models (i.e., serum cystatin C, homocysteine, C-reactive protein, C-reactive protein to albumin ratio, aspartate aminotransferase to platelet ratio index, fibrosis index based on four factors, gamma-glutamyl transpeptidase to platelet ratio, albumin-bilirubin score, and gamma-glutamyl transpeptidase to albumin ratio) that have gained great interest from clinicians. Compared with traditional scoring systems, these serum biomarkers and their models are easily acquired, simple, and relatively inexpensive. In the present review, we summarize the latest studies focused on these serum biomarkers and their models as diagnostic and prognostic indexes in HBV-related liver diseases.

The prognostic and predictive value of the albumin-bilirubin score in advanced pancreatic cancer

Albumin-bilirubin (ALBI) showed its prognostic and predictive value in hepatobiliary disease like hepatocellular carcinoma. However, little has been known about its role in pancreatic cancer.In this retrospective study, 149 patients with advanced pancreatic cancer (APC) treated in the Shanghai General Hospital from January 2009 to December 2014 were enrolled as the training cohort and 120 patients treated from January 2015 to December 2018 were taken as the validation cohort. We generated the ALBI score according previous studies. The correlations between ALBI and clinicopathological parameters were evaluated with the Pearson Chi-square test. Kaplan-Meier method and log-rank test were conducted to determine the correlation between ALBI and overall survival (OS). Then we used Cox regression model to investigate the prognostic significance of ALBI. We further assessed retrospectively whether ALBI score could be used to identify combination therapy candidates for APC.Eastern Cooperative Oncology Group Performance Status, hemoglobin, aspartate aminotransferase, and alanine aminotransferase were found to be significantly correlated with ALBI. Kaplan-Meier analysis showed that the median OS in patients with a pretreatment ALBI ≥-2.6 was 7.0 months, which was significantly shorter than OS of patients with a ALBI <-2.6 (13.0 months, P = .001). ALBI was independently correlated with OS in multivariate analysis. In the subgroup analysis, ALBI showed significant prognostic value in patients with liver metastasis but not those without liver metastasis in all 3 cohorts. In addition, only in the group with ALBI <-2.6, patients receiving combination therapy showed better prognosis than those receiving monotherapy.In conclusion, ALBI was a promising prognostic biomarker in APC with liver metastasis. ALBI also showed predictive value in identifying combination therapy candidates for patients with APC.

Prediction of Sufficient Liver Enhancement on the Gadoxetate Disodium-enhanced Hepatobiliary Phase Imaging Using Transitional Phase Images and Albumin-bilirubin Grade

Purpose:

To investigate whether the contrast enhancement effect in hepatobiliary phase (HBP) images can be predicted using transitional phase (3-min delay) images on liver magnetic resonance imaging (MRI) based on the quantitative liver–spleen contrast ratio (Q-LSC) and albumin–bilirubin (ALBI) grade.

Methods:

Overall, 212 patients (124 men and 88 women; mean age 66.7 ± 11.1 years) who underwent blood tests (assessed within 1 month of performing MRI) were included; patients with diffuse tumor, hepatectomy, splenectomy, Gamna–Gandy bodies in the spleen, and movement artifacts were excluded. Q-LSC was calculated using the signal intensity of the liver divided that of the spleen. Q-LSC > 1.5 (cut-off value) indicates a relatively higher sensitivity for detecting of hepatic lesions. To predict the contrast enhancement effect in HBP using Q-LSC of 3-min delay images, Q-LSC of 10- and 15-min delay images were compared for each ALBI grade based on Q-LSC of 3-min delay images. Furthermore, to verify the accuracy of this prediction, the proportion of cases with Q-LSC > 1.5 in 10- and 15 min delay images was calculated based on Q-LSC on 3-min delay images.

Results:

The higher the Q-LSC on the 3-min delay image, the higher was the Q-LSC on its 10- and 15-min delay images. The proportion of cases with Q-LSC > 1.5 in 10- and 15-min delay images was higher for ALBI grade 1 than for ALBI grades 2 and 3 even in the same Q-LSC on 3-min delay images. Q-LSC was <1 in a 3-min delay image and <1.5 in a 15-min delay image in 62.2% of patients with ALBI grade 1 and 82.1% of patients with ALBI grades 2 and 3.

Conclusion:

The liver contrast enhancement effect in HBP images could be predicted using a 3-min delay image based on Q-LSC and ALBI grade.

Prediction of esophageal varices in patients with HCV-related cirrhosis using albumin-bilirubin, platelets-albumin-bilirubin score, albumin-bilirubin-platelets grade, and GAR

Background

Development of esophageal varices (EVs) is the main complication of portal hypertension. Early detection prevents variceal bleeding. Baveno VI consensus recommended endoscopy if transient elastography (TE) > 20 kPa and platelets below 150,000/mm3.

Aim

Assessment of the reliability of the albumin-bilirubin (ALBI), platelets-albumin-bilirubin (PALBI), albumin-bilirubin-platelets (ALBI-PLT) score, and gamma-glutamyl transferase-platelets (GAR) ratio as non-invasive models for prediction of EVs presence and the need for endoscopy in patients with HCV-related cirrhosis.

Methods

HCV-related F4 fibrosis by TE or cirrhosis patients were included (n = 661). Full metabolic profile, CBC, ultrasonography, and endoscopy were done.

Results

The average age was 42.89 years mainly males. Patients with EVs had statistically significant (p < 0.05) higher TE values, ALBI, ALBI-PLT, and PALBI than those without EVs. Both groups were comparable for GAR. Large varices were statistically (p < 0.05) associated with higher ALBI, ALBI-PLT, and PALBI. Both small and large varices had comparable TE and GAR. EVs detection cutoffs (sensitivity, specificity): TE > 20 kPa (83.64%, 91.62%), ALBI >− 2.43 (81.28%, 74.89%), ALBI-PLT > 3 (77.34%, 72.93%), and PALBI >− 2.28 (62.1%, 76.4%). On comparison of the ROCs, TE was better than ALBI (p < 0.05), ALBI-PLT, and PALBI. ALBI was better than ALBI-PLT and PALBI. Both ALBI-PLT and PALBI are comparable (p > 0.05). Positive indirect hemagglutination of schistosomiasis, portal vein diameter, splenic vein diameter, TE, ALBI, ALBI-PLT, and PALBI were independent predictors of EVs existence. On multivariate analysis, portal vein diameter, TE, and ALBI score were significant.

Conclusion

The ALBI, ALBI-PLT, and PALBI are useful predictors of EVs presence and the need of diagnostic endoscopy especially in centers that lack FibroScan.

Prognostic value of the albumin-bilirubin grade in patients with hepatocellular carcinoma and other liver diseases

One of the most commonly used systems for grading liver function in hepatocellular carcinoma (HCC) patients is the Child-Pugh (CP) score. However, the CP scoring system is not without its shortcomings: for example, the cut-off values for the parameters are calculated arbitrarily and the assessment of ascites and hepatic encephalopathy is subjective. More recently, an alternative to traditional CP grade has emerged in the form of albumin-bilirubin (ALBI) grade. The predictive value provided for HCC patients by the ALBI grade is comparable to that of the CP grade; however, it can also surpass CP grade by greatly reducing subjectivity and further subdividing CP A patients into several different groups, thus improving the prognosis judgment and helping to inform clinicians’ optimal decision-making. The application of the ALBI grade into currently used HCC staging systems such as the Barcelona Clinic Liver Cancer (BCLC) staging system, the Cancer of the Liver Italian Program (CLIP) staging system, and the Japan Integrated Staging (JIS) score, etc., as well as newly produced systems like the ALBI-PLT grade, the ALBI and progression disease (ALBI-PD) grade and Modified Intermediate Stage of Liver Cancer (MICAN) criteria, greatly elevates prognostic power.

Impact of Albumin-Bilirubin Score on Short- and Long-Term Survival After Living-Donor Liver Transplantation: A Retrospective Study

BACKGROUND

The albumin-bilirubin (ALBI) grade, stratified from the ALBI score, may have prognostic value in patients with hepatocellular carcinoma. We aim to evaluate the prognostic abilities of the ALBI score/grade among living-donor liver transplantation patients.

METHODS

We retrospectively collected data of 81 patients who underwent living-donor liver transplant at Kobe University Hospital between June 2000 and October 2018. The efficacy of the ALBI score/grade as a prognostic factor was assessed and compared with that of the well-established Model for End-Stage Liver Disease (MELD) score.

MAIN FINDINGS

Multivariate analysis indicated that recipient age (P = .003), donor age (P = .003), ALBI score ≥ -1.28 (P = .002), and ALBI grade III (P = .004) were independently associated with post-transplant survival. A high MELD score was not associated with post-transplant survival in univariate or multivariate analyses. Although there was no significant difference in the overall survival rate relative to recipient and donor age, ALBI score/grade was significantly associated with the 1- and 5-year survival rates (P = .023, P = .005). ALBI scores specifically detected fatal complications of post-transplant graft dysfunction (P = .031) and infection (P = .020).

CONCLUSION

ALBI score/grade predicted patient survival more precisely than the MELD score did, suggesting that it is a more useful prognostic factor compared to the MELD score in living-donor liver transplantation cases.

Albumin-Bilirubin Score vs Model for End-Stage Liver Disease in Predicting Post-Hepatectomy Outcomes

BACKGROUND

The Albumin-Bilirubin score (ALBI) has been established to predict outcomes after hepatectomy. However, the relative value of ALBI and Model for End-Stage Liver Disease (MELD) in predicting post-hepatectomy liver failure and mortality has not been adequately evaluated. Therefore, the aim of this study was to validate and compare ALBI and MELD with respect to post-hepatectomy liver failure and mortality.

STUDY DESIGN

Patients undergoing major hepatectomy (≥3 segments) or partial hepatectomy (≤2 segments) were identified in the 2014 to 2017 American College of Surgeons NSQIP Procedure Targeted Participant Use File. Univariable and multivariable analyses were performed for 30-day post-hepatectomy liver failure (PHLF) and mortality. Predictive accuracy was assessed using a receiver operator characteristic curve and calculating the area under the curve (AUC).

RESULTS

For 13,783 patients, median ALBI was -2.6, and median MELD score was 6.9. Severe PHLF (grade B to C) and mortality rates were 2.9% and 1.8%, respectively. Multivariable analyses revealed ALBI grade 2/3 to be a stronger predictor than MELD ≥10 with respect to severe PHLF (odds ratio [OR] 2.30; 95% CI, 1.95 to 2.73; p < 0.001 vs OR 1.00; 95% CI, 0.78 to 1.23; p = 0.99) and mortality (OR 3.35; 95% CI, 2.49 to 4.52; p < 0.001 vs OR 1.73; 95% CI, 1.36 to 2.20; p < 0.001). ALBI also had better discrimination compared with MELD for severe PHLF (AUC 0.67 vs AUC 0.60) and mortality (AUC 0.70 vs AUC 0.58) in patients with hepatocellular carcinoma.

CONCLUSIONS

ALBI is a powerful predictor of PHLF and mortality. Compared with MELD, ALBI is more accurate, especially in patients with hepatocellular carcinoma.

Albumin-bilirubin score is associated with response to pegylated interferon and nucleos(t)ide analogues in chronic hepatitis B patients

BACKGROUND AND AIM

Recently, the role of albumin-bilirubin (ALBI) score in chronic hepatitis B (CHB) has not been well-understood. We aimed to investigate the association of ALBI score with natural history of chronic HBV infection and treatment response of CHB patients.

METHODS

The ALBI score in a cohort of 849 individuals including 721 chronic HBV-infected patients naïve to anti-HBV treatment in different phases and 128 healthy controls were estimated. Additionally, the dynamic changes of ALBI score of 243 hepatitis B e antigen (HBeAg)-positive CHB patients treated with pegylated interferon-alpha (PEG-IFN-α) or nucleos(t)ide analogues (NAs) were tested for 72 weeks.

RESULTS

ALBI score differed among phases, with the highest score in HBeAg-positive CHB patients, followed by HBeAg-negative CHB patients, HBeAg-positive chronic HBV infection, and HBeAg-negative chronic HBV infection. Besides, CHB patients harbouring high baseline ALBI score exhibited a relatively stronger therapeutic response to PEG-IFN-α or NAs. Moreover, the rate of HBeAg and HBsAg loss in patients with ALBI grade 2 was persistently higher than that in patients with ALBI grade 1 throughout the course of treatment. Furthermore, ALBI score was an independent predictor of sustained response achievement. The combined use of ALBI score, HBeAg and ALT could enhance the predictive value of treatment response.

CONCLUSIONS

ALBI score differed significantly across the natural course of chronic HBV infection and was correlated with PEG-IFN-α and NAs treatment response in HBeAg-positive CHB patients, which suggested that ALBI score could be useful as an auxiliary clinical factor to determine the initiation of therapy and predict stronger antiviral treatment response.

Comparative evaluation of ALBI, MELD, and Child-Pugh scores in prognosis of cirrhosis: is ALBI the new alternative?

Background:

The existence of reliable prognostic indices is of paramount importance in the management of cirrhosis. Both the model for end-stage liver disease (MELD) score and the older Child-Pugh (CP) scores are widely used. The albumin-bilirubin (ALBI) score, initially used in hepatocellular carcinoma, has not been thoroughly investigated in cirrhosis. The aim of this study was to compare the prognostic accuracy of ALBI, MELD, MELD with sodium (MELD-Na), CP, and the corrected for creatinine CP scores in a genetically homogeneous Cretan cirrhotic population.

Methods:

One hundred ninety-five outpatients or hospitalized cirrhotics (127 male, median age 66 years) were studied over a period of 2 years and ALBI, platelet-albumin-bilirubin, MELD, MELD-Na, CP score, and 2 types of modified CP score (CP-I and CP-II) with serum creatinine were calculated and correlated with survival.

Results:

ALBI had an optimum balance between sensitivity and specificity (area under the curve 0.704, 95% confidence interval [CI] 0.630-0.778) compared to the other scores. In the multivariate analysis, the only factors independently associated with death were the ALBI score (hazard ratio [HR] 2.51, 95%CI 1.69-3.73; P<0.001), the MELD-Na score (HR 1.04, 95%CI 1.00-1.09; P=0.045), and age (HR 1.05, 95%CI 1.03-1.07; P<0.001). When only decompensated cirrhosis was evaluated, the multivariate analysis showed that the ALBI score (HR 3.03; 95%CI 1.92-4.78; P<0.001), and age (HR 1.05, 95%CI 1.03-1.07; P<0.001) were independently associated with death.

Conclusion:

ALBI score might be a better prognostic indicator of mortality in cirrhosis and given its simplicity could substitute for the CP, MELD, and MELD-Na scores.

Combined preoperative albumin-bilirubin (ALBI) and serum γ-glutamyl transpeptidase (GGT) predicts the outcome of hepatocellular carcinoma patients following hepatic resection

Background: Liver function is an important prognostic factor for patients with hepatocellular carcinoma. The purpose of this study was to develop and validate a nomogram integrating the albumin-bilirubin (ALBI) and serum γ-glutamyl transpeptidase (GGT) level to predict postoperative overall survival (OS) and disease-free survival (DFS) of hepatocellular carcinoma (HCC).

Methods: The effect of combined of ALBI and GGT on HCC prognosis was investigated using univariate and multivariate Cox analyses. The nomogram for OS and DFS were developed, respectively, and their predictive ability was compared with other conventional staging systems, including the American Joint Commission on Cancer (AJCC), Barcelona Clinic Liver Cancer (BCLC) and the Cancer of the Liver Italian Program (CLIP).

Results: Combined ALBI and GGT was highly associated with OS (P<0.001) and DFS (P<0.001) of HCC patients treated with hepatic resection. In addition, the C-index of the OS (0.706±0.034) or DFS (0.674±0.032) nomogram in the training cohort was larger than AJCC, BCLC and CLIP. The Akaike information criterion (AICs) of the OS (2178.405) or DFS (2961.018) nomogram in the training cohort was smaller than above staging systems. The results suggested that the OS or DFS nomogram was the most powerful model to predict HCC prognosis. The similar trend was observed in the validation cohort.

Conclusion: The novel nomogram integrating ALBI and GGT was highly associated with OS and DFS of postoperative HCC patients.

Prediction of Transplant-Free Survival through Albumin-Bilirubin Score in Primary Biliary Cholangitis

Albumin–bilirubin (ALBI) grade is defined using the ALBI score, which is calculated based on total serum bilirubin and albumin. This study aimed to evaluate the diagnostic ability of the ALBI score for determining hepatic fibrosis stage and transplant-free survival in primary biliary cholangitis (PBC) patients. A total of 181 Japanese patients with biopsy-proven or serologically diagnosed PBC were enrolled. The pathological stage was assessed using the Scheuer classification. The ALBI score differentiated fibrosis in stage 4 from that of 3 in the biopsy-proven cohort (p < 0.05). With an ALBI score cut-off value of −1.679, the sensitivity and specificity were 100% and 91.1%, respectively, with a likelihood ratio of 12.3 to differentiate stage 4 from stages 1–3. The ALBI score at the beginning of ursodeoxycholic acid (UDCA) prescription correlated with the two prognostic scores calculated after 1-year UDCA treatment. Kaplan–Meier analysis showed that the baseline ALBI score differentiated liver transplant-free survival (p < 0.05). The ALBI score presented a greater hazard ratio for transplant-free survival than aspartate aminotransferase-to-platelet ratio index (APRI) in Cox proportional hazard model. In conclusion, ALBI score indicates pathological stage in Japanese PBC patients and scores before UDCA prescription predict better liver transplant-free survival, which correlated well with the two major prognostic scores. The prognosis-predicting ability of the ALBI score might surpass that of APRI.

The Potential Effects of Diabetes Mellitus on Liver Fibrosis in Patients with Primary Biliary Cholangitis

Background

The impact of diabetes mellitus (DM) on the natural progression of primary biliary cholangitis (PBC) has not yet been determined. The objective of this study was to determine whether DM is associated with increased liver damage in PBC.

Material/Methods

There were 168 treatment-naïve PBC patients, including 37 patients with DM, enrolled in this study between 2012 and 2018. Patient demographics, clinical features, and biochemical and histopathological parameters were collected. Disease severity was assessed by pathological data, Child Pugh grade, and noninvasive indicators. Relevant risks for PBC-related cirrhosis were assessed by univariate and multivariate analyses.

Results

The noninvasive scores predicting fibrosis were all significantly higher in PBC-DM versus PBC-only patients (fibrosis-4 score: 4.08 versus 3.21, P=0.029; aminotransferase-to-platelet ratio index: 1.46 versus 1.09, P=0.036; red blood cell distribution width to platelet ratio: 0.12 versus 0.08, P=0.016; Mayo Risk Score: 1.52 versus 0.19, P=0.011; the Newcastle model: 2.85 versus 2.07, P=0.009; albumin-bilirubin score: −1.92 versus −2.10, P=0.023). Cirrhosis occurred at a higher rate (62.2% versus 42.0%, P=0.030) in PBC-DM patients, but Child Pugh grade and pathological differences could not be accurately determined. A multivariate analysis revealed DM increased the risk of PBC-related cirrhosis, with a resulting adjusted odds ratio of 2.351 (95% confidence interval, 1.022–5.409).

Conclusions

The results of this retrospective, single-center study suggest that DM is associated with more severe liver fibrosis in PBC. Consequently, improved management of DM might alter the prognosis of PBC patients.

Albumin-Bilirubin (ALBI) as an accurate and simple prognostic score for chronic hepatitis B-related liver cirrhosis

BACKGROUND

The Albumin-Bilirubin (ALBI) score was developed to predict the long-term prognosis of hepatocellular carcinoma patients. We aimed to investigate the performance of ALBI for predicting severity and long-term prognosis of chronic hepatitis B-related liver cirrhosis (CHB-LC).

METHODS

CHB-LC patients were enrolled from two medical centers between 2011 and 2017. The prognostic performance of ALBI was evaluated and compared with Child-Turcotte-Pugh (CTP), model of end-stage liver disease (MELD) and MELD integrating sodium (MELD-Na) scores.

RESULTS

This study enrolled 398 CHB-LC patients and patients were followed up for a median of 33.9 (IQR 21.6-48.8) months. The ALBI (HR: 3.151, 95% CI: 2.039-4.869,P < 0.001) was identified as an independent predictor of liver-related mortality. The receiver operating characteristic curves (ROCs) analysis revealed that ALBI score (0.756, 0.745, 0.739, 0.767 and 0.765) was superior to MELD score (P < 0.05) and comparable with CTP score (P > 0.05) for predicting 2-year, 3-year, 4-year, 5-year and global mortality. The AUROCs of ALBI score were significantly higher than MELD-Na score(P < 0.05) for predicting 2-year, 3-year and 5-year mortality. Patients with lower ALBI grade had a significantly lower mortality than patients with higher ALBI grade (P < 0.05).

CONCLUSIONS

ALBI score accurately predicts the severity and long-term prognosis of patients with CHB-LC. The prognostic performance of ALBI score was superior to MELD and MELD-Na score.

Prognosis of 732 ursodeoxycholic acid-treated patients with primary biliary cholangitis: A single center follow-up study from China

BACKGROUND AND AIM

The impact of male sex and past hepatitis B virus (HBV) infection on survival of primary biliary cholangitis (PBC) are issues at discussion. The aim of the present study was to identify risk factors for transplant-free survival (TRS) in Chinese PBC patients who received ursodeoxycholic acid (UDCA), with special focus on the impact of male sex and past HBV infection.

METHODS

We followed up PBC patients who received UDCA at our institute between January 2000 and December 2017 until their death, liver transplantation, or censored on April 1, 2018, by interview and review of medical records. We used Cox proportional hazards model and Kaplan-Meier method.

RESULTS

Out of 976 PBC patients, 732 UDCA-treated patients (female : male = 6.2:1) with required clinical and laboratory data were enrolled in this study. The median follow-up period were 4.8 years (interquartile range: 2.8-7.1 years). The overall 5-, 10-, and 15-year TRS rates were 86.7% (95% CI: 83.8-88.1), 71.1% (95% CI: 65.0-77.2), and 59.2% (95% CI: 44.5-73.9), respectively. The survival was significantly worse for male patients and older patients (≥ 55 years) (log-rank test: P < 0.05 for both). On multivariate analysis, male sex, cirrhosis, serum bilirubin, and serum albumin were independent predictors for TRS. There was no significant difference in survivals between patients with (n = 167) and without (n = 219) past HBV infection (log-rank test: P = 0.293).

CONCLUSIONS

In this large Chinese cohort of UDCA-treated PBC patients, male sex was associated with shorter survival, whereas past HBV infection was not associated with poorer outcome.

Long-term clinical outcomes in patients with autoimmune hepatitis according to treatment response in Asian country

BACKGROUND & AIMS

As surrogate markers for autoimmune hepatitis (AIH), serum alanine aminotransferase (ALT) and immunoglobulin G (IgG) are convenient to measure under immunosuppression. However, the long-term prognosis of patients who achieve complete biochemical remission (CBR) in comparison with patients who achieve only biochemical remission (BR) is uncertain.

METHODS

A total of 291 patients (89.7% female) diagnosed with AIH were retrospectively reviewed. CBR was defined as normal ALT and IgG levels with immunosuppression, while BR was defined as normal ALT levels. CBR was further divided into early CBR (<1year) and late CBR (≥1year) by the timing of remission. Liver-related adverse outcomes including liver-related death, liver transplantation and hepatocellular carcinoma were evaluated.

RESULTS

With immunosuppressive treatment, 222 (76.3%) patients achieved CBR (early CBR: 168 and late CBR: 54). BR was achieved in 55 (18.9%) patients and 14 (4.8%) patients remained non-remission. With a median follow-up duration of 6.6 years, the risk of liver-related mortality was the lowest in patients with CBR, followed by patients with late CBR, BR and non-response. The cumulative risk of liver-related adverse outcomes was the highest in patients with non-response (8.51/100 person-years [PYs]), followed by BR (1.95/100 PYs), late CBR (1.89/100 PYs) and early CBR (0.75/100 PYs). By multivariable analysis, age, cirrhosis and treatment responses were independently associated with liver-related adverse outcomes.

CONCLUSIONS

Patients with CBR within 1 year after treatment initiation had the lowest risk of liver-related adverse outcomes. Patients with late CBR and those with only BR had a comparable risk of long-term outcomes.

Inter- and intra-reader agreement for gadoxetic acid-enhanced MRI parameter readings in patients with chronic liver diseases

Objectives

To examine inter- and intra-observer agreement for four simple hepatobiliary phase (HBP)–based scores on gadoxetic acid (GA)–enhanced MRI and their correlation with liver function in patients with mixed chronic liver disease (CLD).

Methods

This single-center, retrospective study included 287 patients (62% male, 38% female, mean age 53.5 ± 13.7 years) with mixed CLD (20.9% hepatitis C, 19.2% alcoholic liver disease, 8% hepatitis B) who underwent GA-enhanced MRI of the liver for clinical care between 2010 and 2015. Relative liver enhancement (RLE), contrast uptake index (CUI), hepatic uptake index (HUI), and liver-to-spleen contrast index (LSI) were calculated by two radiologists independently using unenhanced and GA-enhanced HPB (obtained 20 min after GA administration) images; 50 patients selected at random were reviewed twice by one reader to assess intra-observer reliability. Agreement was assessed by intraclass correlation coefficient (ICC). The albumin-bilirubin (ALBI) score, the model of end-stage liver disease (MELD), and the Child-Turcotte-Pugh (CTP) score were calculated as standards of reference for hepatic function.

Results

Intra-observer ICCs ranged from 0.814 (0.668–0.896) for CUI to 0.969 (0.945–0.983) for RLE. Inter-observer ICCs ranged from 0.777 (0.605–0.874) for HUI to 0.979 (0.963–0.988) for RLE. All HBP-based scores correlated significantly (all p < 0.001) with the ALBI, MELD, and CTP scores and were able to discriminate patients with a MELD score ≥ 15 versus ≤ 14, with area under the curve values ranging from 0.760 for RLE to 0.782 for HUI.

Conclusion

GA-enhanced, MRI-derived, HBP-based parameters showed excellent inter- and intra-observer agreement. All HBP-based parameters correlated with clinical and laboratory scores of hepatic dysfunction, with no significant differences between each other.

Key Points

• Radiological parameters that quantify the hepatic uptake of gadoxetic acid are highly reproducible.

• These parameters can be used interchangeably because they correlate with each other and with scores of hepatic dysfunction.

• Assessment of these parameters may be helpful in monitoring disease progression.

The ability of the new ALBI scoring in predicting mortality, complications and prognostic comparison among cirrhotics

Introduction

Albumin-bilirubin (ALBI) is a newly devised scoring system for prognostication of liver cirrhosis. The ALBI has recently been validated and found superior to Child-Turcotte-Pugh score (CTP) and Model for End stage Liver Disease (MELD) in assessing severity of liver disease.

Aim

To determine the ALBI score's mortality prediction among cirrhotics, associated complications and to compare its prognostic proficiency to that of MELD and CTP.

Material and methods

The diagnostic accuracy of CTP, MELD and ALBI scores for mortality in hospitalized cirrhotic patients was determined by receiver operating characteristic curve (ROC) analysis. The areas under the ROC curve were calculated, with confidence intervals (CI) of 95%. The best cut-off values were ascertained with the greatest specificity and sensitivity.

Results

The study showed overall in-hospital mortality of 25.5%. Median CTP score was 10.2 (IQR = 3) and area under curve (AUC) was 0.842 (95% CI: 0.817-0.868, p < 0.001) with sensitivity of 75.0% and specificity of 79.2%. Median MELD score was 20.9 (IQR = 7.2) and AUC was 0.836 (95% CI: 0.810-0.863, p < 0.001) with sensitivity of 76.6% and specificity of 76.7%. Median ALBI score was -1.1 (IQR = 1.0), and AUC of ALBI was 0.852 (95% CI: 0.826-0.879, p < 0.001) with sensitivity and specificity of 78.1%.

Conclusions

The objective prognostication and easy utilization of ALBI make it a useful alternative to MELD and CTP and therefore favour its applicability in clinical practice. Further validations in large prospective cohorts are needed for prognostic value of ALBI in cirrhosis and its complications.
