Assessment of the prognosis of cirrhosis: Child-Pugh versus MELD

Serum Cystatin C Predicts Mortality in HBV-Related Decompensated Cirrhosis

Background

Some studies have reported that renal dysfunction is associated with poor prognosis in cirrhotic patients. Serum cystatin C (CysC) is an accurate biomarker for early renal dysfunction. This study aimed to assess the prognostic value of serum CysC levels in patients with hepatitis B virus-related decompensated cirrhosis (HBV-DeCi).

Methods

This retrospective study included 75 subjects who had been diagnosed with HBV-DeCi. The association between serum CysC and prognosis was estimated by receiver operating characteristic curve analysis and a multivariable logistic regression model.

Results

Serum CysC levels were higher in nonsurvivors than in survivors and were positively correlated with model for end-stage liver disease (MELD) scores. In multivariate analysis, CysC and the MELD score were independent prognostic factors in all HBV-DeCi patients. However, only serum CysC was an independent factor predicting mortality in patients with normal creatinine levels.

Conclusions

These data suggest that high serum CysC levels can be considered an independent biomarker of 3-month mortality in patients with HBV-DeCi.

Serum Ferritin Levels: A Potential Biomarker to Represent Child-Turcotte-Pugh Score among Decompensated Liver Cirrhosis Patients

Background

Liver cirrhosis and the child-Turcotte-Pugh (CTP) score are inseparable entities in liver disease. CTP score is largely known as the mortality and prognosis predictor. Nevertheless, ferritin emerges as a simple biomarker related to prognosis. The study aimed to determine whether there was a significant correlation between serum ferritin levels and CTP score.

Methods

The study analysed 54 decompensated liver cirrhotic patients including 17 females and 37 males between May 2016 and May 2017 at the Haji Adam Malik General Hospital, Medan, Indonesia. Ferritin levels were, then, divided into trichotomous cut-off value (< 200 ng/mL, n = 22; 200–400 ng/mL, n = 5; and > 400 ng/mL, n = 27). Data was analysed using SPSS version 12.0 (continuous variables were assessed by the Kruskal-Wallis test and Chi-square test was used for categorical variables). In addition, Spearman correlation test was used to determine any significant correlation between ferritin levels and CTP score.

Results

Based on data analysis, gender and CTP score were related to higher ferritin levels (P = 0.002 and P = 0.018, respectively). Furthermore, a significant correlation between serum ferritin levels and CTP score was obtained in to moderate degree (P = 0.000; r = 0.487).

Conclusions

There might be a significant role of serum ferritin levels in predicting mortality and prognosis among decompensated liver cirrhosis patients but it still needs further attention.

Shear wave elastography prior to transjugular intrahepatic portosystemic shunt may predict the decrease in hepatic vein pressure gradient

BACKGROUND

Transjugular intrahepatic portosystemic shunt (TIPS) is a procedure used to treat portal hypertension complications. Our aim was to evaluate liver and spleen stiffness measurement (LSM and SSM, respectively) changes using acoustic radiation force impulse imaging (ARFI) in comparison to Child-Pugh scores for predicting hepatic venous pressure gradient (HVPG) decreases after TIPS implantation.

METHODS

This prospective study included 31 consecutive clinically significant portal hypertension patients with TIPS indication. All patients received LSM and SSM before TIPS, at baseline, 2 days (follow-up 1) and 6 weeks (follow-up 2) post-implantation. HVPG was performed during the TIPS procedure.

RESULTS

The mean decrease in HVPG after TIPS was 63%. LSM and SSM decreased significantly between baseline and follow-up 2 (p < 0.001 and p < 0.001, respectively). At baseline, follow-up 1 and follow-up 2, significant correlations were detected between mean SSM and mean HVPG (p = 0.026; p = 0.018; p = 0.002, respectively). HVPG decreased to ≤ 10 mmHg in 61% of patients for which LSM, SSM, and Child-Pugh score were predictors (p = 0.033, p = 0.002 and p = 0.030, respectively). The area under the curve (AUC) for LSM, SSM, and Child-Pugh was 0.88, 0.90, and 0.84, respectively, with close sensitivity and specificity. SSM had the highest diagnostic accuracy for predicting an HVPG decrease to ≤ 10 mmHg in comparison to LSM and Child-Pugh score.

CONCLUSION

Spleen stiffness is superior to liver stiffness and Child-Pugh score as a non-invasive surveillance tool for evaluating patients with clinically significant portal hypertension (HVPG ≥ 10 mmHg) prior to TIPS.

The risk factors of portal vein thrombosis in patients with liver cirrhosis

This study was designed to identify and assess risk factors for portal vein thrombosis (PVT) in patients with cirrhosis. A total of 98 cirrhosis patients with PVT were identified and 101 cirrhosis patients without PVT were chosen as the control group in this retrospective study. Several variables were measured and the two groups PVT and non-PVT were compared statistically. PVT was identified in 98 patients (10%). Significant differences in hematocrit, international normalized ratio, albumin, bilirubin and glucose were determined between the groups (P<0.05). Out of the thrombophilic risk factors in the patients with PVT factor V Leiden was identified in 8.8%, prothrombin gene 6.6% and methylenetetrahydrofolate reductase 2.2%. There was no difference in survival time between groups (P>0.05).

Preoperative aspartate aminotransferase-to-platelet-ratio index as a predictor of posthepatectomy liver failure for resectable hepatocellular carcinoma

Purpose

This study aimed to investigate the efficacy of preoperative aspartate aminotransferase-to-platelet-ratio index (APRI) score to predict the risk of posthepatectomy liver failure (PHLF) in patients with hepatocellular carcinoma (HCC) after liver resection, and to compare the discriminatory performance of the APRI with the Child–Pugh score, model for end-stage liver disease (MELD) score, and albumin–bilirubin (ALBI) score.

Patients and methods

A total of 1,044 consecutive patients with HCC who underwent liver resection were enrolled and studied. Univariate and multivariate analyses were performed to investigate risk factors associated with PHLF. Predictive discrimination of Child–Pugh, MELD, ALBI, and APRI scores for predicting PHLF were assessed according to area under the ROC curve. The cutoff value of the APRI score for predicting PHLF was determined by ROC analysis. APRI scores were stratified by dichotomy to analyze correlations with incidence and grade of PHLF.

Results

PHLF occurred in 213 (20.4%) patients. Univariate and multivariate analyses revealed that Child–Pugh, MELD, ALBI, and APRI scores were significantly associated with PHLF. Area under the ROC analysis revealed that the APRI score for predicting PHLF was significantly more accurate than Child–Pugh, MELD, or ALBI scores. With an optimal cutoff value of 0.55, the sensitivity and specificity of the APRI score for predicting PHLF were 72.2% and 68.0%, respectively, and the incidence and grade of PHLF in patients with high risk (APRI score >0.55) was significantly higher than in the low-risk cohort (APRI score <0.55).

Conclusion

The APRI score predicted PHLF in patients with HCC undergoing liver resection more accurately than Child–Pugh, MELD, or ALBI scores.

Improved survival following splenectomy combined with curative treatments for hepatocellular carcinoma in Child B patients: A propensity score matching study

AIMS

To explore the benefits of curative treatments (liver resection or local ablation) combined with splenectomy for patients with hepatocellular carcinoma (HCC) and Child grade B liver function.

METHODS

We reviewed 245 patients with Child grade B liver function who underwent treatment with curative intent for HCC. Among these patients, 116 patients underwent curative treatment combined with splenectomy (the splenectomy group); the other 129 patients only underwent curative treatment (the non-splenectomy group). A one-to-one matching produced 95 paired patients, perioperative and oncological outcomes were compared, and liver function changes were reassessed 1 year later.

RESULTS

The perioperative liver failure rates were 7.4% and 6.3% (P = 1.000) and the 90-day mortality was 4.2% and 6.3% (P = 0.747) in the splenectomy group and non-splenectomy group, respectively. The 1-, 3-, and 5-year overall survival rates were remarkably greater in the splenectomy group than in the non-splenectomy group (92.6% vs. 79.8%, 53.4% vs. 34.7%, and 19.9% vs. 11.0%, respectively; P = 0.004). In the univariate and multivariate analyses, splenectomy was identified as a protective factor for long-term survival. The proportion of patients whose liver function improved to Child A 1 year after surgery was also higher in the splenectomy group than in the non-splenectomy group (95.4% vs. 83.3%; P = 0.048).

CONCLUSIONS

Compared with non-splenectomy, curative treatments combined with splenectomy for patients with HCC and Child B grade liver function showed no different perioperative outcomes but achieved significant survival benefit. Splenectomy is a beneficial factor for patients with HCC and Child B liver function; liver function improved significantly 1 year after splenectomy.

Albi Score as a Predictor of Survival in Patients with Compensated Cirrhosis Resected for Hepatocellular Carcinoma: Exploratory Evaluation in Relationship to Palbi and Meld Liver Function Scores

The aim of the study was to explore predictive value of the ALBI, PALBI and MELD scores on survival in patients resected for hepatocellular carcinoma with compensated liver cirrhosis and no macrovascular infiltration. In this retrospective study, longitudinal survival analysis was performed. We analyzed patient/tumor characteristics and MELD, ALBI and PALBI scores as liver function tests for predicting survival outcome. Survival was analyzed from the date of liver resection until death, liver transplantation, or end of follow-up. Patients were stratified for age, cirrhosis etiology, presence of esophageal varices, hepatocellular carcinoma stage, microvascular invasion, histologic differentiation, and resection margins. We identified 38 patients (alcoholic cirrhosis in 84.2% of patients) resected over an 8-year period. Median preoperative MELD score was 8, ALBI score -2.63, and PALBI score -2.38. During the follow-up period, 24 patients died. Estimated median survival time was 36 months. Microvascular invasion was observed in 33 patients. Higher ALBI score was associated with 23.1% higher relative risk of death. PALBI score was associated with 12.1% higher relative risk of death, whereas MELD score was not associated with the risk of death. In conclusion, ALBI score demonstrated significant predictive capabilities for survival in patients with compensated cirrhosis resected for hepatocellular carcinoma.

Management of diabetes mellitus in patients undergoing liver transplantation

Diabetes is a common feature in cirrhotic individuals both before and after liver transplantation and negatively affects prognosis. Certain aetiological agents of chronic liver disease and loss of liver function per se favour the occurrence of pre-transplant diabetes in susceptible individuals, whereas immunosuppressant treatment, changes in lifestyle habits, and donor- and procedure-related factors contribute to diabetes development/persistence after transplantation. Challenges in the management of pre-transplant diabetes include the profound nutritional alterations characterizing cirrhotic individuals and the limitations to the use of drugs with liver metabolism. Special issues in the management of post-transplant diabetes include the diabetogenic potential of immunosuppressant drugs and the increased cardiovascular risk characterizing solid organ transplant survivors. Overall, the pharmacological management of cirrhotic patients undergoing liver transplantation is complicated by the lack of specific guidelines reflecting the paucity of data on the impact of glycaemic control and the safety and efficacy of anti-hyperglycaemic agents in these individuals.

Alteration in gut microbiota associated with hepatitis B and non-hepatitis virus related hepatocellular carcinoma

BACKGROUND

The onset of hepatocellular carcinoma (HCC) ranked fifth malignancies all over the world. Increasing evidences showed that the distribution of HCC was related to the incidence of chronic hepatitis B virus (HBV) infection and other factors, such as alcoholism, aflatoxin B1 ingestion and obesity. Recent studies demonstrated that gut dysbiosis plays an important role in liver diseases. However, the researches on gut microbiota of HBV and non-HBV non-HCV related HCC have not been reported. In this study, we investigated the differences between the gut microbiota of HBV related HCC (B-HCC) and non-HBV non-HCV related HCC (NBNC-HCC), finally found some potential bacteria, linking different pathological mechanism of both types of HCCs.

RESULTS

We carried out 16S rRNA analyses in a cohort of 33 healthy controls, 35 individuals with HBV related HCC (B-HCC) and 22 individuals with non-HBV non-HCV (NBNC) related HCC (NBNC-HCC). We found that the species richness of fecal microbiota of B-HCC patients was much higher than other two groups. Interestingly, the feces of NBNC-HCC patients harbored more potential pro-inflammatory bacteria (Escherichia-Shigella, Enterococcus) and reduced levels of Faecalibacterium, Ruminococcus, Ruminoclostridium which results in decrease potential of anti-inflammatory short-chain fatty acids. The feces of NBNC-HCC patients had relatively fewer abundance of multiple biological pathways related to amino acid and glucose metabolism, but high level of transport and secretion in some types. However, the B-HCC patients had opposite results of bacterial composition and associated multiple biological pathways versus NBNC-HCC patients. Meanwhile, we found that aberrant network of gut microbiota occurred differently in B-HCC and NBNC-HCC patients.

CONCLUSIONS

Our study indicated that B-HCC and NBNC-HCC patients showed differential abundance of bacteria involved in different functions or biological pathways. We suggested the modification of specific gut microbiota may provide the therapeutic benefit for B-HCC and NBNC-HCC.

Benefits of Splenectomy and Curative Treatments for Patients with Hepatocellular Carcinoma and Portal Hypertension: a Retrospective Study

BACKGROUND

We aimed to explore the benefit of splenectomy combined with curative treatments (liver resection or local ablation) for patients with hepatocellular carcinoma and portal hypertension.

METHODS

The records of 239 patients with hepatocellular carcinoma and portal hypertension undergoing either splenectomy combined with liver resection or local ablation were reviewed retrospectively. Perioperative complications and survival outcome were evaluated, and liver function 1 year later was reassessed according to the Child score.

RESULTS

The post-hepatectomy liver failure rates and 30-day mortality were 3.3% and 2.1%, respectively. The 1-, 3-, and 5-year overall survival rates were 95.1%, 73%, and 47.5% for patients with Child grade A and 92.2%, 51.2%, and 19.8% for Child grade B, respectively. The median survival time for patients with Child scores of 5, 6, 7, 8, and 9 were 61.5, 51.3, 44.8, 33.7, and 23.4 months, respectively. After multivariable analysis, tumor size, tumor number, post-hepatectomy liver failure, and Child score were independent risk factors for overall survival. Liver function was converted to Child grade A in 98 of 101 patients (97%) who had preoperative Child grade B 1 year after splenectomy.

CONCLUSION

Patients with hepatocellular carcinoma and portal hypertension can benefit from splenectomy combined with curative treatments, especially those with Child scores of 5, 6, and 7. Liver function improved significantly 1 year after splenectomy in patients with preoperative Child grade B.

ALBI and PALBI Grades Are Associated with the Outcome of Patients with Stable Decompensated Cirrhosis

INTRODUCTION AND AIM

Studies carried out mainly in patients with hepatocellular carcinoma (HCC), have shown the prognostic significance of albumin-bilirubin (ALBI) grade. Recently, another predictive score incorporating platelet count into ALBI, PALBI grade, was introduced in patients with HCC.

AIM

We evaluated the ability of ALBI and PALBI grades in predicting the outcome (mortality / liver transplantation) of patients with stable decompensated cirrhosis with various etiology of liver diseases.

MATERIAL AND METHODS

We prospectively studied 325 patients with stable decompensated cirrhosis awaiting liver transplantation. Their clinical and laboratory characteristics were recorded including albumin, bilirubin levels, platelets. We estimated ALBI and PALBI grades for every patient. Conventional prognostic scores were also evaluated; Child-Pugh (CTP), Model for End stage Liver Disease (MELD). We followed them up and recorded their outcome.

RESULTS

Beyond MELD and CTP, ALBI and PALBI grades proved significant factors associated with the outcome (HR: 2.13, 95%CI [1.59, 2.85], p < 0.001 and HR: 2.06, 95%CI [1.47, 2.9], p < 0.001, respectively), and their predictive capability was established (ROC analysis; AUC: 0.695, 95% CI [0.634, 0.755] and AUC: 0.683, 95% CI [0.621,0.744], respectively). ALBI and PALBI performed better than CTP score (p = 0.0044 and p = 0.014, respectively). Categorization of our patients into three ALBI groups detected statistically different survival times. Accordingly, PALBI grade 3 compared to those with PALBI grade 1 and 2 patients, had worse outcome and significantly higher frequency of cirrhosis-related complications Conclusions. ALBI and PALBI grades were validated and can be used to predict the outcome in patients with stable decompensated cirrhosis.

Scoring systems for prediction of mortality in decompensated liver cirrhosis: A meta-analysis of test accuracy

AIM

To compare the accuracy of the scoring systems Child-Turcotte-Pugh (CTP), Model for End-stage Liver Disease score (MELD), MELD-Na, and MELD to Serum Sodium ratio (MESO) to predict the mortality in decompensated liver cirrhosis.

METHODS

The PubMed, Web of Science, Cochrane Library, EMBASE, and Ovid databases were systematically searched from inception to September 2018 for relevant articles, and we evaluated the quality of the included studies. The accuracy of scoring systems was analyzed with Stata 12 and MetaDiSc 1.4.

RESULTS

Sixteen studies involving 2337 patients were included. The pooled areas under the summary receiver operating characteristic curves (AUROCs) of CTP, MELD, MELD-Na, and MESO to predict mortality were 0.81, 0.78, 0.85, and 0.86, respectively. Within 3 mo, the AUROCs of CTP, MELD, and MELD-Na in predicting mortality were 0.78, 0.76, and 0.89, respectively. The AUROCs of CTP, MELD, and MELD-Na at 3 mo were 0.86, 0.78, and 0.86, respectively. The AUROCs of CTP, MELD, and MELD-Na at 6 mo were 0.91, 0.83, and 0.90, respectively. The AUROCs of CTP, MELD, and MELD-Na at 12 mo were 0.72, 0.75 and 0.84, respectively. In cirrhotic patients with bleeding, the AUROCs of CTP and MELD were 0.76 and 0.88, respectively.

CONCLUSION

MESO has the highest AUROC in all assessed scoring systems. Considering the different time points, MELD-Na has good accuracy in predicting the mortality of decompensated liver cirrhosis. Compared to CTP, MELD is better in predicting variceal bleeding.

Managing diabetes and liver disease association

There is strong association between liver diseases and diabetes (DM) which is higher than expected by a chance association of two very common disorders. It can be classified into three categories: Liver disease related to diabetes, hepatogenous diabetes (HD), and liver disease occurring coincidentally with DM. The criteria for the diagnosis of diabetes associating liver disease are the same for primary diabetes. Two hours post glucose load is a better screening test for HD. HbA1c may not be suitable for diagnosis or monitoring of diabetes associating advanced liver disease. Apart from the increased cardiovascular risk in patients with type 2 DM (T2 DM) and NAFLD, the cardiovascular and retinopathy risk is low in HD. Patients with metabolic derangement should be screened for NAFLD which in turn may predict T2 DM development. Similarly, patients with established T2 DM should also be screened for NAFLD which further contributes to diabetes worsening. Diabetes is a significant risk factor for progression of the chronic liver disease. It is associated with poor patient survival. Treatment of diabetes associating liver disease appears beneficial. Metformin, if tolerated and not contraindicated, is recommended as a first-line therapy for patients with diabetes and chronic liver disease (CLD). If the hepatic disease is severe, insulin secretagogues should be avoided because of the increased risk of hypoglycaemia. Pioglitazone may be useful in patients with fatty liver disease. DPP-4 inhibitors showed effectiveness and safety for the treatment of T2 DM in CLD patients up to those with child B stage. GLP-1 receptor agonists and SGLT-2 inhibitors exhibit positive effects on weight and are associated with minimal risk of hypoglycaemia. Insulin must be used with caution, as hypoglycaemia may be a problem. Insulin analogues are preferred in the context of hypoglycaemia Statins can be used to treat dyslipidaemia in NAFLD, also the use of angiotensin II receptor antagonist for hypertension is safe and beneficial Given the clear association between diabetes mellitus and hepatocellular carcinoma, the strict control of glycaemia with insulin sensitizers can be essential in its prevention. The addition of DM to the currently used scores (Child-Pugh and MELD scores) may enhance the sensitivity and the specificity for prediction of morbidity and mortality rates in cirrhotic patients. In the new era of directly acting antiviral agents (DAAs) for HCV treatment, it is recommended to follow up lipid profile and blood sugar levels following SVR in order to adjust doses of medications used in diabetic (SVR is associated with reduction in insulin requirements) and dyslipidaemic patients (rebound increase in the lipid profile after clearing the virus may increase risk of cardiovascular disease (CVD)). The issues of post liver transplant diabetes and relation between DM and chronic HBV are highlighted. This narrative review and Consensus-based practice guidance (under revision and criticism) are based on a formal review and analysis of the recently published world literature on the topic (Medline search up to September 2017); and the experience of the authors and independent reviewers.

Transient elastography can stratify patients with Child-Pugh A cirrhosis according to risk of early decompensation

BACKGROUND

Compensated cirrhosis has a variable prognosis depending on stage. There are currently no straightforward and robust tools in clinical practice to predict decompensation in Child-Pugh A cirrhosis. We set out to determine whether transient elastography (TE) could be used across liver disease aetiologies to determine risk of decompensation.

PATIENTS AND METHODS

Participants were enrolled at two sites (Dublin and Nottingham) and followed up for a minimum of 2 years. The primary outcome of the study was liver decompensation, defined as the development of overt hepatic encephalopathy or ascites or presentation with bleeding varices. All patients received a TE examination to measure liver stiffness measurement (LSM) and had routine blood measurements taken at the baseline visit and on each subsequent visit.

RESULTS

In 259 participants, the overall rate of liver-related outcome was 31 per 1000 person-years (95% confidence interval: 19-47 per 1000 person-years). Of the total population, 6 and 11% developed a liver-related outcome within 2 and 4 years of follow-up, respectively. There were no events in the population with a LSM less than 21 kPa. A LSM of more than 35 kPa was associated with a decompensation risk of 39% at 4 years. For each unit increase in the LSM above 20 kPa, the risk of liver-related outcome increased by 6% (hazard ratio=1.06; 95% confidence interval: 1.04-1.82) after adjusting for age, sex Mayo End Liver Disease Score, cohort source and aetiology.

CONCLUSION

The risk of liver decompensation increased with increasing LSM in mixed aetiology compensated cirrhosis. LSM may be used to risk stratify patients, potentially reassure patients with low scores, and select patients with higher scores for experimental therapeutic studies with acceptable timelines.

Supportive and palliative care in people with cirrhosis: International systematic review of the perspective of patients, family members and health professionals

BACKGROUND & AIMS

People with cirrhosis have unmet needs, which could benefit from a palliative care approach. Developing effective services needs to be based on evidence from those with personal experience. This review aims to explore; patient and family perspectives of perceived needs including communication; health professionals' perspectives on delivery of care and improving palliative care between specialities.

METHODS

A literature search was conducted in Medline, Embase and CINAHL using key words reporting on the perspectives of patients with liver cirrhosis (18 years and over), family members or health professionals on the provision of care in liver cirrhosis. Study quality was assessed using the Mixed Methods Appraisal Tool. Qualitative and quantitative findings were grouped together according to the main relevant themes identified.

RESULTS

Nineteen research studies predominantly from high-income Western countries were identified, with a total sample consisting of 1,413 patients, 31 family carers and 733 health professionals. Patients and family members had limited understanding of cirrhosis or its impact. They wanted better information about their disease, its treatment and help with psychological and practical needs. Health professionals had difficulty communicating about these issues to patients and their families. General practitioners left care predominantly to the liver clinicians, who lacked confidence to have discussions about prognosis or future care preferences. The role of palliative care was recognised as important in caring for this group through earlier integration with liver and community services.

CONCLUSIONS

Health professionals need support to improve their communication with patients, to address patients' broader needs beyond medical treatment and to develop new models to improve palliative care coordination between different medical specialities. Future research should focus on developing communication aides, testing existing tools to identify suitable patients for supportive care and exploring robust ways of evaluating supportive care interventions, with more studies needed from middle- and low-income countries. Registration number: PROSPERO CRD42017064770.

LAY SUMMARY

Patients and their families had a poor understanding of advanced liver disease and its impact on them. They need more information about the treatments they receive and how to get practical and psychological support. Liver specialists and GPs found it difficult to talk to patients and their families about the seriousness of advanced liver disease and the lack of healthcare options available to them if their condition gets worse. All doctors and nurses involved in the care of patients with advanced liver disease recognise that palliative and supportive care have an important role in improving patient care.

Acute Variceal Bleeding: Does Octreotide Improve Outcomes in Patients with Different Functional Hepatic Reserve?

BACKGROUND

Current guidelines do not differentiate in the utilization of vasoactive drugs in patients with cirrhosis and acute variceal bleeding (AVB) depending on liver disease severity.

MATERIAL AND METHODS

In this retrospective study, clinical outcomes in 100 patients receiving octreotide plus endoscopic therapy (ET) and 216 patients with ET alone were compared in terms of failure to control bleeding, in-hospital mortality, and transfusion requirements stratifying the results according to liver disease severity by Child-Pugh (CP) score and MELD.

RESULTS

In patients with CP-A or those with MELD &lt; 10 octreotide was not associated with a better outcome compared to ET alone in terms of hospital mortality (CP-A: 0.0 vs. 0.0%; MELD &lt; 10: 0.0 vs. 2.9%, p = 1.00), failure to control bleeding (CP-A: 8.7 vs. 3.7%, p = 0.58; MELD &lt; 10: 5.3 vs. 4.3%, p = 1.00) and need for transfusion (CP-A: 39.1 vs. 61.1%, p = 0.09; MELD &lt; 10: 63.2 vs. 62.9%, p = 1.00). Those with severe liver dysfunction in the octreotide group showed better outcomes compared to the non-octreotide group in terms of hospital mortality (CP-B/C: 3.9 vs. 13.0%, p = 0.04; MELD ≥ 10: 3.9 vs. 13.3%, p = 0.03) and need for transfusion (CP-B/C: 58.4 vs. 71.6%, p = 0.05; MELD ≥ 10: 50.6 vs. 72.7%, p &lt; 0.01). In multivariate analysis, octreotide was independently associated with in-hospital mortality (p = 0.028) and need for transfusion (p = 0.008) only in patients with severe liver dysfunction (CP-B/C or MELD ≥ 10).

CONCLUSION

Patients with cirrhosis and AVB categorized as CP-A or MELD &lt; 10 had similar clinical outcomes during hospitalization whether or not they received octreotide.

Comparison of the ability of Child-Pugh score, MELD score, and ICG-R15 to assess preoperative hepatic functional reserve in patients with hepatocellular carcinoma

BACKGROUND

Assessing hepatic functional reserve before hepatectomy is beneficial to reduce the incidence of posthepatectomy liver failure (PHLF). This study aimed to compare the ability of the Child-Pugh score, model for end-stage liver disease (MELD) score, and retention test at 15 minutes (indocyanine green [ICG]-R15) to assess hepatic functional reserve.

METHODS

A total of 185 patients with hepatocellular carcinoma (HCC) undergoing hepatectomy were enrolled in this study. The ability of Child-Pugh score, MELD score, and ICG-R15 predicting severe PHLF were compared.

RESULTS

A total of 23 patients (12.4%) developed severe PHLF. Multivariate analyses identified that platelet count, ICG-R15, clinically significant portal hypertension, and major resection were independent factors for predicting severe PHLF. The area under the receiver operating characteristic curve of ICG-R15 for predicting severe PHLF was higher than that of both Child-Pugh score and MELD score. With an optimal cutoff value of 7.1%, the sensitivity and specificity of ICG-R15 for predicting severe PHLF were 52.2% and 89.5%, respectively. Both the incidence of severe PHLF and mortality in patients with ICG-R15 >7.1% were significantly higher than the figures for patients with ICG-R15 ≤7.1%.

CONCLUSION

ICG-R15 is more accurate than the Child-Pugh score and MELD score in predicting hepatic functional reserve before hepatectomy.

Long-term clinical outcomes in patients with viral hepatitis related liver cirrhosis after transjugular intrahepatic portosystemic shunt treatment

Background

Transjugular intrahepatic portosystemic shunt (TIPS) procedure has played a vital role in management of portal hypertension. Thus, we aimed to investigate the natural history, long-term clinical outcome, predictors of survival in viral hepatitis related cirrhotic patients post-TIPS.

Method

A total of 704 patients with complete followed-up data were enrolled, and clinical characteristics of patients were collected and analyzed. Kaplan-Meier method was used to calculate survival, and comparisons were made by log rank test. A multivariate analysis of factors influencing survival was carried out using the Cox proportional hazards regression model.

Results

TIPS implatantion significantly decreased portal vein pressure with 9.77 cmH₂O reduction, without influencing long-term liver functions. The total incidence rate of major complication post-TIPS, including HE and re-bleeding/bleeding, was 37.9% and 15.5%, respectively. Patients in Child-Pugh C stage revealed higher overt hepatic encephalopathy (HE) occurrence (65.6%), while patients receiving covered, 6 mm in diameter stents indicated notably lower incidence of HE in comparison with other groups (6.4%). The median survival was > 60 months, 27.0 months, and 11.5 months in cirrhotic patients with variceal bleeding, refractory ascites, and both complications, respectively. The cumulative 5-year survival was significantly higher in patients with variceal bleeding (75.6%) in comparison with either that in patients with refractory ascites (12.5%) or that in patients with both complications (1.96%) (P < 0.0001). Covered stents usage, baseline model for end-stage liver disease (MELD) score, and baseline Child-Pugh classification were predictive of survival (P < 0.001). Other variables including age, male gender, and pre-TIPS PVP were not emerged as significant predictors (P > 0.05).

Conclusion

TIPS was an effective and safe therapeutic method for decompression of portal hypertension and for treatment of its complications. Careful selection of patients with minimal liver dysfunction for TIPS implantation was essential for better long-term outcomes.

Outcome of endoscopic retrograde cholangiopancreatography in patients with clinically defined decompensated liver cirrhosis

OBJECTIVE

Decompensated liver cirrhosis (LC) can negatively affect the outcome of endoscopic retrograde cholangiopancreatography (ERCP). We aimed to compare the efficacy and safety of ERCP in patients with clinically defined compensated and decompensated LC.

METHODS

In a single tertiary hospital, 146 endoscopic sphincterotomy-naive patients with LC who underwent ERCP between 2005 and 2016 were reviewed. Patients with LC who had experienced variceal bleeding, ascites or hepatic encephalopathy were included in the decompensated LC group. Cannulation, technical and clinical successes, and major post-ERCP adverse events including bleeding, pancreatitis, cholangitis and perforation were compared between the two groups.

RESULTS

Patients were divided into compensated and decompensated LC groups. Their baseline characteristics were not different, except for comorbid malignancy (22.3 % vs 38.5%, P = 0.038) and preprocedural transfusion (7.4% vs 36.5%, P < 0.001). The cannulation (97,9% vs 94.2%, P = 0.348) and technical (95.7% vs 88.5%, P = 0.167) success rates were not different. The clinical success rate was lower in the decompensated LC group (95.7% and 78.8%, P = 0.003), mainly due to comorbid hepatobiliary malignancy. Post-ERCP pancreatitis (6.4% vs 30.8%, P = 0.008) and cholangitis (18.1% vs 32.7%, P = 0.046) rates were higher in the decompensated LC group.

CONCLUSIONS

Despite lower clinical success rates due to comorbid hepatobiliary malignancy, ERCP in patients with decompensated LC is technically feasible. Because postprocedural cholangitis and pancreatitis are more frequent in patients with decompensated LC, greater procedural precautions are needed in these patients.

Safety and Effectiveness of Suture-mediated Arterial Closure Device in Hepatocellular Carcinoma Patients Who Underwent Drug-Eluting Beads Transarterial Chemoembolization

BACKGROUND

The number of transarterial percutaneous procedures has risen over the years, consequently reducing puncture site related complications has become a necessity. To this end, the use of arterial closure devices has been growing progressively and their benefits have become a focus of research. The purpose of this study is to assess the safety and effectiveness of a suture-mediated closure device, Perclose ProGlide^® (Abbott Vascular, Redwood City, CA), in patients with liver disease and hepatocellular carcinoma who underwent transarterial liver chemoembolization with drug-eluting beads.

MATERIALS AND METHODS

A cohort of 253 hepatocellular carcinoma patients who underwent 449 procedures of transarterial liver chemoembolization with drug-eluting beads using the Perclose Proglide device was prospectively studied. The main endpoints evaluated were the technical success of the device, defined as complete hemostasis achieved within 3 min after the closure, and the incidence of puncture-site complications. The secondary endpoints evaluated were the correlation between epidemiological factors, coagulation profile and degree of liver disease, and the occurrence of complications.

RESULTS

Technical success was achieved in 96% of the cases. Among patients who underwent repeated procedures using the same vascular access, this rate was 95.3%. Puncture-site complications were observed in 7 procedures (1.56%); 4 (0.89%) were due to hemorrhage, 2 (0.44%) hematomas and 2 (0.44%) pseudoaneurysms; 2 (0.44%) due to limb ischemia; and 1 (0.22%) due to arterial dissection. Among them, 3 cases required intervention. The statistical analysis of demographic characteristics, Child-Pugh classification, and coagulation status did not show a significant correlation with the occurrence of complications. Of the 449 procedures, only 4 (0.89%) needed hospitalization due to puncture-site complications.

CONCLUSIONS

The use of Perclose Proglide is safe and effective in patients with liver disease and hepatocellular carcinoma who underwent transarterial liver chemoembolization with drug-eluting beads.

Validation of a Symptoms Distress Scale in a Cirrhotic Population Using Item Response Theory

BACKGROUND

The assessment of symptoms distress is an important strategy for symptoms management and treatment of patients with liver cirrhosis (LC); however, appropriate instruments are limited.

OBJECTIVE

The objective of this study was to validate a symptoms distress scale (SDS) by confirming the appropriateness of each item using item response theory.

METHODS

A cross-sectional and convenience sampling was conducted to recruit eligible cirrhotic outpatients from the gastroenterology outpatient department of a single medical university hospital. In total, 163 patients with LC completed the 21-item SDS. A graded response model with two-parameter (discrimination and difficulty) estimation was used for data analysis.

RESULTS

The item response theory model identified the validity of the SDS and found that most of the items in the SDS represented a high level of symptoms distress; moreover, three items of bruising, drowsiness, and dark urine were reported in cirrhotic patients with severe symptom distress. Four items comprising bodily pain, right upper quadrant pain, muscle cramps, and change in appearance can be appropriately represented in cirrhotic patients with mild symptoms distress. Moreover, the amount of test information in the SDS was >0.70, indicating acceptable reliability.

DISCUSSION

Items of the SDS can be useful for assessing different levels of symptoms distress; however, using the scale to assess mild symptoms distress in populations with LC should be done with great caution.

Predictors of clinical outcomes in cirrhosis patients

PURPOSE OF REVIEW

The current review aims to explain the different systems available to clinicians for predicting clinical outcomes in patients with cirrhosis.

RECENT FINDINGS

Cirrhosis is the final stage of chronic liver disease and is associated with high morbidity and mortality. The most commonly utilized tools to predict outcomes in patients with cirrhosis include the following: assessing severity of portal hypertension using hepatic venous pressure gradient (HVPG) measurements, using scoring systems such as the Model for End-stage Liver Disease (MELD) and Child-Pugh-Turcotte (CPT) scores, and recently, clinical staging systems based on cirrhosis-related clinical complications. Assessing portal pressure with HVPG measurements provides valuable prognostic information, yet is costly, time-consuming, and invasive. MELD and CPT scores can be calculated quickly and not only assess liver function, but also yield predictive information. However, they represent only one point in time, and do not take into account the full clinical picture. Clinical staging systems have traditionally been focused on compensated and decompensated stages, with newer models assessing the influence of cirrhosis-related complications. However, these are not commonly utilized.

SUMMARY

Predicting clinical outcomes in patients with cirrhosis is challenging, and is likely best accomplished with a combination of objective data (such as MELD and HVPG provide) in addition to the clinical course of cirrhosis.

MicroRNA profiles in serum samples from patients with stable cirrhosis and miRNA-21 as a predictor of transplant-free survival

MicroRNAs (miRNAs) have remarkable potential as diagnostic and prognostic markers because of their roles in disease pathogenesis. miRNAs can be released into the bloodstream, where they are sufficiently stable to be detected noninvasively. Here, we prospectively evaluated serum levels of miR-21, miR-34a, miR-122, miR-181b, and miR-885-5p in patients with stable cirrhosis. Total RNA was extracted from the sera of patients with cirrhosis and healthy individuals, and the expression levels of the target miRNAs were analyzed by reverse transcription-quantitative polymerase chain reaction. Serum miRNAs levels were correlated with liver function parameters, etiology, and complications of cirrhosis. Circulating miR-34a, miR-122, and miR-885-5p levels were higher in patients with cirrhosis than in healthy individuals. These miRNAs were positively correlated with alanine aminotransferase and aspartate aminotransferase levels, and the relative expression levels were higher in hepatitis C virus-infected patients and lower in patients with Child-Pugh C cirrhosis. miR-122 and miR-885-5p levels were also positively correlated with γ-glutamyl transpeptidase concentrations. miR-21 was associated with transplant-free survival in univariate Cox regression analysis and remained independently associated with survival after adjustment for age, Child-Pugh classification, Model for End-stage Liver Disease score, and history of previous decompensation in multivariate Cox regression analysis. These data suggested that miR-34a, miR-122, and miR-885-5p levels may be more related to the inflammatory process and ongoing hepatocyte damage in patients with cirrhosis. Moreover, miR-21 levels were independently associated with shorter transplant-free survival and may be used as a prognostic tool in outpatients with stable cirrhosis.

Assessment of prognostic performance of Albumin-Bilirubin, Child-Pugh, and Model for End-stage Liver Disease scores in patients with liver cirrhosis complicated with acute upper gastrointestinal bleeding

OBJECTIVE

The Albumin-Bilirubin (ALBI) score was developed recently to assess the severity of liver dysfunction. We aimed to assess its prognostic performance in patients with liver cirrhosis complicated with upper gastrointestinal bleeding (UGIB) while comparing it with Child-Pugh (CP) and Model for End-stage Liver Disease (MELD) scores.

PATIENTS AND METHODS

This was a retrospective unicentric study, including consecutive adult patients with cirrhosis admitted for UGIB between January 2011 and November 2015. Clinical, analytical, and endoscopic variables were assessed and ALBI, CP, and MELD scores at admission were calculated.

RESULTS

This study included 111 patients. During the first 30 days of follow-up, 12 (10.8%) patients died, and during the first year of follow-up, another 10 patients died (first-year mortality of 19.8%).On comparing the three scores, for in-stay and 30-day mortality, only the ALBI score showed statistically significant results, with an area under the curve (AUC) of 0.80 (P<0.01) for both outcomes. For first-year mortality, AUC for ALBI, CP, and MELD scores were 0.71 (P<0.01), 0.64 (P<0.05), and 0.66 (P=0.02), respectively, whereas for global mortality, AUC were 0.75 (P<0.01), 0.72 (P<0.01), and 0.72 (P<0.01), respectively. On comparing the AUC of the three scores, no significant differences were found in first-year mortality and global mortality.

CONCLUSION

In our series, the ALBI score accurately predicted both in-stay and 30-day mortality, whereas CP and MELD scores could not predict these outcomes. All scores showed a fair prognostic prediction performance for first-year and global mortality. These results suggest that the ALBI score is particularly useful in the assessment of short-term outcomes, with a better performance than the most commonly used scores.

2D shear wave elastography combined with MELD improved prognostic accuracy in patients with acute-on-chronic hepatitis B liver failure

OBJECTIVES

To evaluate accuracy of two-dimensional shear wave elastography (2D SWE) and develop and validate a new prognostic score in predicting prognosis of acute-on-chronic liver failure (ACLF) patients.

METHODS

From 1 October 2013 to 30 September 2015, we consecutively enrolled 290 patients, sequentially collected data (including 2D SWE, ultrasound parameters, laboratory data and prognostic scores) and recorded patients' outcome (recovering/steady or worsening) during a 90-day follow-up period. We evaluated ability of 2D SWE to predict outcomes of acute-on-chronic hepatitis B liver failure (ACLF-HBV) patients. We developed a new score (MELD-SWE, combining MELD and SWE values) for predicting mortality risk of ACLF-HBV in 179 patients in a derivation group, and validated in 111 patients.

RESULTS

2D SWE values were higher in worsening patients than recovering/steady ones (p < 0.001). Accuracy of 2D SWE in predicting outcomes of ACLF-HBV was comparable to that of the MELD score (p = 0.441). MELD-SWE showed a significantly higher prognostic value than MELD in both derivation (AUROC, 0.80 vs. 0.76, p = 0.040) and validation (AUROC, 0.87 vs. 0.82, p = 0.018) group.

CONCLUSIONS

The MELD-SWE score, combining MELD and SWE values, was superior to MELD alone for outcoming prediction in patients with ACLF-HBV.

KEY POINTS

• 2D SWE is a simple prognostic evaluation tool in patients with ACLF-HBV. • MELD-SWE was created in this study: 1.3×MELD + 0.3×2D SWE (kPa). • MELD-SWE score was superior to MELD alone for outcoming prediction in ACLF-HBV. • In this study, 46.8 was the optimal cut-off value of MELD-SWE score.

Comparison of five different scoring models for predicting short-term mortality in patients with alcohol-related acute-on-chronic liver failure

AIM

To compare the performance of age, bilirubin, INR, and creatinine (ABIC), Maddrey's discriminant function (MDF), model for end-stage liver disease (MELD), chronic liver failure-sequential organ failure assessment (CLIF-SOFA), and Child-Turcotte-Pugh (CTP) in predicting short-term mortality in patients with alcohol-related acute-on-chronic liver failure (ACLF).

METHODS

There were 462 consecutive patients with live failure treated from August 2005 to June 2017 at Tianjin Third Central Hospital, of whom 152 with alcohol-related ACLF were finally enrolled in this study according to the inclusion criteria and exclusion criteria. We divided patients into either group A or group B. Patients in group A met the criteria of Asian Pacific Association for the Study of the Liver but did not met the criteria of European Association for the Study of the Liver-Chronic Liver Failure (EASL-CLIF), and patients in group B met the criteria of EASL-CLIF on admission. The performance of different scoring models in predicting short-term mortality was assessed using the area under the receiver operating characteristic curve (AUC-ROC).

RESULTS

The 28-d mortality rate was 19% in group A and 50% in group B (P = 0.002). In group A, the AUC of CLIF-SOFA for predicting the 28-d mortality was highest (0.889), followed by MELD (0.761), MDF (0.738), ABIC (0.718), and CTP (0.671), and there was a significant difference between CTP and the others. In group B, the AUC of CLIF-SOFA was 0.916, followed by MELD (0.804), MDF (0.770), ABIC (0.729), and CTP (0.647), and there was a significant difference between CLIF-SOFA and the others and between CTP and the others.

CONCLUSION

The five scoring systems could all predict the short-term prognosis of the two groups of patients. However, CLIF-SOFA performs well compared to the others, regardless of patients in group A or group B.

Model for End-Stage Liver Disease and Seven Derivations to Prioritize Liver Transplant Candidates: Which Is the Winner?

OBJECTIVES

Under the present liver transplant policy, patients with the highest risk of death receive preference for organ placement. The aim of this study was to evaluate the Model for End-stage Liver Disease (MELD) and seven prognostic derivatives of this test for outcome prediction in cirrhotic patients on liver transplant wait lists.

MATERIAL AND METHODS

The study included 416 patients (65.9% male; age 49 ± 13.9 years) who were entered to liver transplant wait lists from January 2013 to October 2016. Study endpoints were 3-month, 6-month, and 1-year mortality.

RESULTS

All prognostic models had acceptable overall performances (0.12 < Brier score < 0.21). The MELD-to-serum sodium ratio test outperformed its counterparts at all 3 endpoints. Estimated C statistics ranged from 0.77 to 0.83. The largest value at 3 months was for the 5-variable MELD score (0.83), and the largest value at 6 months (0.82) and 1 year (0.83) was for the MELD-albumin score. The Hosmer-Lemeshow goodness-of-fit test and calibration plots revealed underestimation for the entire range of predicted risk (P < .001). With decision curve analysis, the MELD-to-serum sodium ratio and United Kingdom Model for End-Stage Liver Disease scoring tests covered the most extensive range of optimal threshold probabilities.

CONCLUSIONS

Although some derivations, including sodium and albumin, showed effective prioritization of liver transplant candidates, poor calibration statistics highlighted the need for a recalibration process as an inevitable prerequisite before daily clinical use of these tests at the individual level.

Effectiveness of the MELD/Na Score and the Child-Pugh Score for the Identification of Palliative Care Needs in Patients with Cirrhosis of the Liver

Objective:

Identification of palliative care needs in patients with liver cirrhosis using the MELD/Na score and the Child–Pugh score.

Materials and Methods:

A retrospective study of hospitalized patients with hepatic cirrhosis between January 2015 and December 2016 using the Child–Pugh score and the MELD/Na score in January 2018.

Results:

Recognizing end-of-life patients (the past 12 months of life) is a challenge for health professionals, especially in diseases with poorly defined criteria, such as cirrhosis of the liver. The verification of rapid functional decline and health indicators can be verified using already defined scales such as the Child–Pugh score and the MELD/Na score. Patients were classified according to the Child–Pugh score in Class A (17%), Class B (48.9%), and Class C (34%). The corresponding survival rate was as follows: class A (87.5%), Class B (30.4%), and Class C (31.25%). The MELD/Na score intervals were >9 (2.15%), score 10–19 (46.8%), score 20–29 (27.7%), score 30–40 (19.1%), and score >40 (4.3%). Nearly 51.1% had a MELD/Na score >20 and 48.9% <20. The study revealed that 59.6% of patients died before 12 months. They were end-of-life patients who needed palliative care to reduce the impact of the disease.

Conclusions:

The Child–Pugh score and the MELD/Na score represent a viable and easy-to-use tool to identify patients in need of palliative care, among those with liver cirrhosis. Early identification, timely evaluation, and effective treatment of physical, spiritual, family, and social problems improve the quality of life of people with incurable diseases and their families.

Nutrition and Muscle in Cirrhosis

As the cirrhosis progresses, development of complication like ascites, hepatic encephalopathy, variceal bleeding, kidney dysfunction, and hepatocellular carcinoma signify increasing risk of short term mortality. Malnutrition and muscle wasting (sarcopenia) is yet other complications that negatively impact survival, quality of life, and response to stressors, such as infection and surgery in patients with cirrhosis. Conventionally, these are not routinely looked for, because nutritional assessment can be a difficult especially if there is associated fluid retention and/or obesity. Patients with cirrhosis may have a combination of loss of skeletal muscle and gain of adipose tissue, culminating in the condition of "sarcopenic obesity." Sarcopenia in cirrhotic patients has been associated with increased mortality, sepsis complications, hyperammonemia, overt hepatic encephalopathy, and increased length of stay after liver transplantation. Assessment of muscles with cross-sectional imaging studies has become an attractive index of nutritional status evaluation in cirrhosis, as sarcopenia, the major component of malnutrition, is primarily responsible for the adverse clinical consequences seen in patients with liver disease. Cirrhosis is a state of accelerated starvation, with increased gluconeogenesis that requires amino acid diversion from other metabolic functions. Protein homeostasis is disturbed in cirrhosis due to several factors such as hyperammonemia, hormonal, and cytokine abnormalities, physical inactivity and direct effects of ethanol and its metabolites. New approaches to manage sarcopenia are being evolved. Branched chain amino acid supplementation, Myostatin inhibitors, and mitochondrial protective agents are currently in various stages of evaluation in preclinical studies to prevent and reverse sarcopenia, in cirrhosis.

Impact of Acute Kidney Injury on Mortality of Patients Hospitalized for Complications of Cirrhosis

BACKGROUND/AIMS

The mortality of hospitalized patients for complications of cirrhosis is very high. We examined the independent predictors of mortality, particularly the impact of increments in creatinine, in 339 consecutive patients (636 admissions) who were admitted for complications of cirrhosis.

METHODS

Clinical characteristics, biochemical parameters including serum creatinine levels at various time intervals, and mortality data were recorded for all admissions. Data were analyzed for initial as well for all repeated admissions to identify independent predictors of mortality.

RESULTS

The in-hospital mortality, 30-day, 90-day, 180 days, and 365 days mortality were 6%, 15%, 23%, 30%, and 41% respectively. Those admitted with spontaneous bacterial peritonitis had the worst survival. Increase in creatinine was noted in 29% of patients and they had lower 30-day (78% vs.91%) and 90-day (73% vs. 82%) survival than those without increase in creatinine. Any increment in serum creatinine (≥0.1 mg/dL) within 48 h after admission (peak 48 h - admission) was associated with a step-wise increase in mortality, but only if peak creatinine reached above 1.2 mg/dL. If peak creatinine levels were below 1.2 mg/dL, increases in serum creatinine had no impact on survival. Cox regression analysis showed that increments in serum creatinine of 0.3 mg/dL or higher had the worst outcome (HR 2.51, CI 1.65-3.81). Etiology of cirrhosis or the use of PPI, beta blockers or rifaxamin did not predict mortality. Other independent predictors of mortality were age, reason for admission, hyponatremia, and INR.

CONCLUSION

In patients with cirrhosis, any increment in serum creatinine within 48 h from hospitalization is associated with a higher mortality provided the peak serum creatinine within 48 h is above 1.2 mg/dL.

Echocardiographic and Electrocardiographic Predictors of Adverse Outcomes in Spontaneous Bacterial Peritonitis

BACKGROUND

Patients with cirrhosis who develop Spontaneous Bacterial Peritonitis (SBP) suffer from cirrhotic cardiomyopathy which is characterized by impaired contractility in response to stress despite a relatively normal resting cardiac output. We hypothesized that electrocardiographic and echocardiographic information would help prognosticate patients developing SBP in addition to existing scoring systems.

METHODS

Cirrhotic patients admitted to Einstein Medical Center from 01/01/2005 to 6/30/2012 for SBP, and did not receive a transplant within one year, were included. Patients were classified as QTc low vs. high, and E/E' low vs. high at cut points ≥480 ms for QTc and ≥10 for E/E' ratio. We estimated 1-year survival using Kaplan Meier curves. Regression analysis and Cox proportional hazards model were used for QTc and E/E' ratio, respectively, for assessing 1-year survival.

RESULTS

Among 112 patients with electrocardiogam, 78 were classified as QTc low. Among 64 patients with echocardiograms, 23 were classified as E/E' low. Higher QTc was associated with increased in-hospital acute kidney injury. QTc and E/E' ratio predicted worse 1-year survival (HR = 2.16, 95% CI 1.29-3.49; HR 2.65, 95% CI 1.31-5.35, respectively) on univariate and multivariate analysis (OR = 1.02, 95% CI 1.01-1.03; HR = 3.26, 95% CI 1.22-9.82 respectively) after adjusting for both Child Pugh stage, MELD score among other risk factors.

CONCLUSION

In conclusion, cirrhotic patients with SBP who present with a prolonged QTc interval are at a greater risk for acute renal failure during hospitalization. High QTc duration and an E/E' ratio of ≥10 independently predict increased mortality at 1-year follow-up.

Modified model for end-stage liver disease improves short-term prognosis of hepatitis B virus-related acute-on-chronic liver failure

AIM

To investigate whether the short-term prognosis of hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF) could be improved by using a modified model for end-stage liver disease (MELD) including serum lactate.

METHODS

This clinical study was conducted at the First Affiliated Hospital, Fujian Medicine University, China. From 2009 to 2015, 236 patients diagnosed with HBV-related ACLF at our center were recruited for this 3-month follow-up study. Demographic data and serum lactate levels were collected from the patients. The MELD scores with or without serum lactate levels from survival and non-survival groups were recorded and compared.

RESULTS

Two hundred and thirty-six patients with HBV-ACLF were divided into two groups: survival group (S) and non-survival group (NS). Compared with the NS group, the patients in survival the S group had a significantly lower level of serum lactate (3.11 ± 1.98 vs 4.67 ± 2.43, t = 5.43, P < 0.001) and MELD score (23.33 ± 5.42 vs 30.37 ± 6.58, t = 9.01, P = 0.023). Furthermore, serum lactate level was positively correlated with MELD score (r = 0.315, P < 0.001). Therefore, a modified MELD including serum lactate was developed by logistic regression analysis (0.314 × lactate + 0.172 × MELD - 5.923). In predicting 3-month mortality using the MELD-LAC model, the patients from the S group had significantly lower baseline scores (-0.930 ± 1.34) when compared with those from the NS group (0.771 ± 1.32, t = 9.735, P < 0.001). The area under the receiver operating characteristic curve (AUROC) was 0.859 calculated by using the MELD-LAC model, which was significantly higher than that calculated by using the lactate level (0.790) or MELD alone (0.818). When the cutoff value was set at -0.4741, the sensitivity, specificity, positive predictive value and negative predictive value for predicting short-term mortality were 91.5%, 80.10%, 94.34% and 74.62%, respectively. When the MELD-LAC scores at baseline level were set at -0.5561 and 0.6879, the corresponding mortality rates within three months were 75% and 90%, respectively.

CONCLUSION

The short-term prognosis of HBV-related ACLF was improved by using a modified MELD including serum lactate from the present 6-year clinical study.

Comparison of 10- and 20-min hepatobiliary phase images on Gd-EOB-DTPA-enhanced MRI T1 mapping for liver function assessment in clinic

PURPOSE

To compare hepatobiliary phase (HBP) images obtained 10 and 20 min after Gd-EOB-DTPA-enhanced MRI for liver function assessment in clinic on 3.0 T MR imaging.

METHODS

103 patients were separated into four groups: 38 patients for the normal liver function (NLF) group, 33 patients for the liver cirrhosis with Child-Pugh A (LCA) group, 21 patients for the liver cirrhosis with Child-Pugh B group, and 11 patients for a liver cirrhosis with Child-Pugh C group. T1 relaxation times (T1rt) were measured on T1 mapping and reduction rates of T1rt (rrT1rt) were calculated. HBP images were obtained at the 10- and 20-min mark after Gd-EOB-DTPA enhancement.

RESULTS

T1rt on pre-enhancement imaging showed no significant difference (p > 0.05) among all four groups. T1rt for both the 10-min HBP and the 20-min HBP showed a significant difference (p < 0.05) among all groups, but showed no significant difference (p > 0.05) between the NLF group and the LCA group. T1rt and rrT1rt showed no significant difference (p > 0.05) between 10-min HBP and 20-min HBP among all groups. The ROC analysis on 10-min HBP and 20-min HBP showed a lower diagnostic performance between NLF group and LCA group (AUC from 0.532 to 0.582), but high diagnostic performance (AUC from 0.788 to 1.000) among others group.

CONCLUSIONS

In comparing 10-min HBP and 20-min HBP T1 mapping after Gd-EOB-DTPA enhancement, our results suggest that 10-min HBP T1 mapping is a feasible option for quantitatively assessing liver function.

Cirrhosis of Liver and Diabetes Mellitus: The Diabolic Duo?

Introduction

Cirrhosis of the liver and diabetes mellitus are two chronic illnesses with significant impact on the quality of life. Studies from different part of the world have shown the combination to be associated with higher incidence of complications of cirrhosis and reduced survival. However, data on the impact of pre-cirrhotic and post-cirrhotic diabetes on cirrhosis is minimal.

Aim

The aim of the study was to determine the complications of cirrhosis patients with and without co-existent DM and to compare the relation between cirrhosis patients with antecedent DM and hepatogenous DM.

Materials and Methods

The present prospective study was conducted at a tertiary care hospital in Kerala, India, over a period of three years. Cirrhosis patients with and without diabetes, along with subcategorization as antecedent and hepatogenous diabetes, were studied for various complications and outcome including death. Chi-square and Mann-whitney tests were used for comparing data.

Results

Patients with cirrhosis and diabetes had higher incidence of gall stones (27.6% versus 13.2%; p=0.008) and urinary infection (29.3% versus 7.5%; p=<0.001). Incidence of hepatocellular carcinoma and mortality were similar between the groups. Patients with antecedent diabetes and hepatogenous diabetes were similar with respect to complications and mortality. Child-Turcotte-Pugh (CTP) score, Model for End stage Liver Disease (MELD) score, urinary tract and respiratory infections and duration of cirrhosis were independent predictors of mortality in patients with cirrhosis.

Conclusion

Coexistent diabetes mellitus increases the incidence of complications and hospitalizations in cirrhosis patients but without impact on mortality rates. There is no significant morbidity or mortality difference between cirrhotics with antecedent diabetes and hepatogenous diabetes.

Risk Factors for Post-Transplant Death in Donation after Circulatory Death Liver Transplantation

PURPOSE

In spite of the increasing success of liver transplantation, there remains inevitable risk of postoperative complications, re-operations, and even death. Risk factors that correlate with post-transplant death have not been fully identified.

MATERIALS AND METHODS

We performed a retrospective analysis of 65 adults that received donation after circulatory death liver transplantation. Binary logistic regression and Cox's proportional hazards regression were employed to identify risk factors that associate with postoperative death and the length of survival period.

RESULTS

Twenty-two recipients (33.8%) deceased during 392.3 ± 45.6 days. The higher preoperative Child-Pugh score (p = .007), prolonged postoperative ICU stay (p = .02), and more postoperative complications (p = .0005) were observed in deceased patients. Advanced pathological staging (p = .02) with more common nerve invasion (p = .03), lymph node invasion (p = .02), and para-tumor satellite lesion (p = .01) were found in deceased group. The higher pre-transplant Child-Pugh score was a risk factor for post-transplant death (OR = 4.38, p = .011), and was correlated with reduced post-transplant survival period (OR = 0.35, p = .009). Nerve invasion was also a risk factor for post-transplant death (OR = 13.85, p = .014), although it failed to affect survival period.

CONCLUSIONS

Our study emphasizes the impact of recipient's pre-transplant liver function as well as pre-transplant nerve invasion by recipient's liver cancer cells on postoperative outcome and survival period in patients receiving liver transplantation.

Serum cholinesterase: A predictive biomarker of hepatic reserves in chronic hepatitis D

AIM

To determine the predictive performance of cholinesterase compared to existing prognostic models in evaluating liver function in patients with chronic hepatitis D.

METHODS

In an observational, cross-sectional and retrospective study, consecutive patients with hepatitis D cirrhosis were evaluated. Demographic, clinical and laboratory parameters were recorded. Serum cholinesterase levels were correlated with existing scoring models for chronic liver disease and Liver function tests. Receiver operating characteristic (ROC) curves were constructed to find an optimal cholinesterase level predicting ascites, Child Turcotte Pugh (CTP) score ≥ 10, model for end stage liver disease (MELD) score ≥ 15, baseline-event-anticipation (BEA) score for hepatitis D ≥ 5 and the aspartate transaminase to Platelet Ratio Index (APRI) ≥ 1.5.

RESULTS

This study investigated 233 patients with chronic liver disease due to hepatitis D; 192 were male, median age 42 (16-69 years). Fifty patients had ascites and 15 had encephalopathy. One hundred and sixty-seven (71.7%) were in Child class A, 52 (22.3%) in Child class B and 14 (5.0%) in class C. A MELD score of 15 or more was seen in 24 patients. Cholinesterase levels correlated well with the INR, albumin, CTP score, MELD, MELD sodium, BEA and APRI scores (P < 0.001 each). Area under the ROC curve for ascites, CTP ≥ 10, MELD ≥ 15, BEA ≥ 5, APRI ≥ 1.5 was 0.836, 0.966, 0.913, 0.871 and 0.825 respectively (P < 0.001 each). Cut off values of cholinesterase (IU/L) for predicting ascites, CTP ≥ 10, MELD ≥ 15, BEA ≥ 5 and APRI ≥ 1.5 were < 3812, < 2853, < 2829, < 4719 and < 3954 with a sensitivity of 80%, 100%, 91.67%, 82.50%, 58.0% and specificity of 81.97%, 84.79%, 87.56%, 77.06% and 55.64% respectively.

CONCLUSION

Serum cholinesterase demonstrates promising correlations with serum albumin, INR and CTP, MELD, BEA and APRI scores and is predictive of liver reserves in hepatitis D cirrhosis.

Enhanced recovery after surgery program reduces length of hospital stay and complications in liver resection: A PRISMA-compliant systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Many enhanced recovery after surgery (ERAS) guidelines have already been established in several kinds of surgeries. But due to concerns of the specific complications, it has not yet been considered the standard of care in liver surgery.

OBJECTIVE

The aim of this review is to assess the effect of ERAS in patients undergoing liver surgery.

METHODS

EMBASE, CNKI, PubMed, and the Cochrane Database were searched for randomized controlled trials (RCTs) comparing ERAS with conventional care in patients undergoing liver surgery. Subgroup meta-analysis between laparoscopic and open surgical approaches to liver resection was also conducted.

RESULTS

Seven RCTs were included, representing 996 patients. Length of stay (LOS) (MD -3.17, 95% CI: -3.99 to -2.35, P < .00001, I = 89%) and time to first flatus (MD -0.9, 95% CI: -1.36 to -0.45, P = .0001, I = 98%) were both reduced in the ERAS group. There were also fewer complications in the ERAS group (OR 0.52, 95% CI: 0.37-0.72, P < .0001, I = 0%).

CONCLUSION

The ERAS program can obviously enhance short-term recovery after liver resection. It is safe and worthwhile. A specific ERAS guideline for liver resection is recommended.

Prognostic Value of a New Marker of Ventricular Repolarization in Cirrhotic Patients

Background

There is still debate about the relationship between changes in ventricular repolarization on the surface electrocardiogram and cirrhosis severity.

Objective

To study the relationship between variables related to ventricular repolarization and the clinical severity of the cirrhotic disease.

Methods

We selected 79 individuals with hepatic cirrhosis, classified according to the Child-Pugh-Turcotte criteria (Child A, B, and C). We measured the QT and corrected QT (QTc) intervals, and the interval between the peak and the end of the T wave (TpTe), and we identified their minimum, maximum, and mean values in the 12-lead electrocardiogram. We also calculated the dispersion of the QT (DQT) and QTc (DQTc) intervals.

Results

In 12 months of clinical follow-up, nine subjects underwent hepatic transplantation (Child A: 0 [0%]; Child B: 6 [23.1%]; Child C: 3 [18.8%]; p = 0.04) and 12 died (Child A: 3 [12.0%]; Child B: 4 [15.4%]; Child C: 5 [31.3%]; p = 0.002). No significant differences were observed between the cirrhotic groups related to the minimum, maximum, and mean values for the QT, QTc, TpTe, DQT, and DQTc intervals. A minimum TpTe interval ≤ 50 ms was a predictor for the composite endpoints of death or liver transplantation with a sensitivity of 90% and a specificity of 57% (p = 0.005). In the Cox multivariate analysis, the Child groups and a minimum TpTe of ≤ 50 ms were independent predictors of the composite endpoints.

Conclusion

The intervals QT, QTc, DQT, DQTc, and TpTe have similar distributions between different severity stages in cirrhotic disease. The TpTe interval proved to be a prognostic marker in subjects with cirrhosis, regardless of disease severity (NCT01433848).

Natural History of T1N0M0 Hepatocellular Carcinoma: Large-Scale Study in the United States

BACKGROUND

Hepatocellular carcinoma (HCC) prognosis depends on clinicopathological features in addition to the treatment provided. We aimed to assess the natural history of TNM stage I HCC tumors which received different treatment over a period of 20 years.

METHODS

Between 1992 and 2011, a total of 397 stage I HCC patients were included. Detailed information was retrieved from MD Anderson Cancer Center patients' medical records. The Kaplan-Meier method was used to calculate patients' overall survival (OS). Cox regression analysis was used to calculate the estimated hazard ratio and 95% confidence interval of different prognostic factors.

RESULTS

Out of 397 patients, 67.5% were males, 42.8% had hepatitis-related HCC, and 59.7% had underlying cirrhosis. After adjustment for confounding factors, we found that all therapeutic modalities were associated with a significant mortality rate reduction with an OS of 63, 42.03, 34.3, and 22.1 months among patients treated with surgery, ablation, local, and systemic therapy, respectively. A restricted analysis of cirrhotic and noncirrhotic patients showed that ablative and local therapy were significantly associated with a longer OS compared to systemic therapy.

CONCLUSION

TNM stage I HCC patients have a favorable prognosis regardless of the type of treatment. Notably, ablative and local therapy significantly improved OS compared to systemic therapy.

Clinical Features of Refractory Ascites in Outpatients

OBJECTIVES:

To present the clinical features and outcomes of outpatients who suffer from refractory ascites.

METHODS:

This prospective observational study consecutively enrolled patients with cirrhotic ascites who submitted to a clinical evaluation, a sodium restriction diet, biochemical blood tests, 24 hour urine tests and an ascitic fluid analysis. All patients received a multidisciplinary evaluation and diuretic treatment. Patients who did not respond to the diuretic treatment were controlled by therapeutic serial paracentesis, and a transjugular intrahepatic portosystemic shunt was indicated for patients who required therapeutic serial paracentesis up to twice a month.

RESULTS:

The most common etiology of cirrhosis in both groups was alcoholism [49 refractory (R) and 11 non-refractory ascites (NR)]. The majority of patients in the refractory group had Child-Pugh class B cirrhosis (p=0.034). The nutritional assessment showed protein-energy malnutrition in 81.6% of the patients in the R group and 35.5% of the patients in the NR group, while hepatic encephalopathy, hernia, spontaneous bacterial peritonitis, upper digestive hemorrhage and type 2 hepatorenal syndrome were present in 51%, 44.9%, 38.8%, 38.8% and 26.5% of the patients in the R group and 9.1%, 18.2%, 0%, 0% and 0% of the patients in the NR group, respectively (p=0.016, p=0.173, p=0.012, p=0.012, and p=0.100, respectively). Mortality occurred in 28.6% of the patients in the R group and in 9.1% of the patients in the NR group (p=0.262).

CONCLUSION:

Patients with refractory ascites were malnourished, suffered from hernias, had a high prevalence of complications and had a high postoperative death frequency, which was mostly due to infectious processes.

Hepatogenous diabetes: Is it time to separate it from type 2 diabetes?

By definition, hepatogenous diabetes is directly caused by loss of liver function, implying that it develops after cirrhosis onset. Therefore, it should be distinguished from type 2 diabetes developing before cirrhosis onset, in which specific causes of liver disease play a major role, in addition to traditional risk factors. Currently, although hepatogenous diabetes shows distinct pathophysiological and clinical features, it is not considered as an autonomous entity. Recent evidence suggests that the failing liver exerts an independent "toxic" effect on pancreatic islets resulting in β-cell dysfunction. Moreover, patients with hepatogenous diabetes usually present with normal fasting glucose and haemoglobin A_1c levels and abnormal response to an oral glucose tolerance test, which is therefore required for diagnosis. This article discusses the need to separate hepatogenous diabetes from type 2 diabetes occurring in subjects with chronic liver disease and to identify individuals suffering from this condition for prognostic and therapeutic purposes.

Performance of Disease-Specific Scoring Models in Intensive Care Patients with Severe Liver Diseases

INTRODUCTION

Egypt has the highest prevalence of Hepatitis C Virus (HCV) in the world, estimated nationally at 14.7%. HCV treatment consumes 20% ($80 million) of Egypt's annual health budget. Outcomes of cirrhotic patients admitted to the ICU may, in fact, largely depend on differences in the state of the disease, criteria and indications for admission, resource utilization, and intensity of treatment.

AIM

The aim of the present study was to evaluate the efficacy of liver specific scoring models in predicting the outcome of critically ill cirrhotic patients in the ICU as it may help in prioritization of high risk patients and preservation of ICU resources.

MATERIALS AND METHODS

Over one year, a total of 777 patients with End Stage Liver Disease (ESLD) due to HCV infection were included in this retrospective non-randomized human study. All statistical analyses were performed by the statistical software SPSS version 22.0 (SPSS, Chicago, IL, USA). Child Turcotte Pugh (CTP) score, MELD score, MELD-Na, MESO, iMELD, Refit MELD and Refit MELD-Na were calculated on ICU admission.

RESULTS

ICU admission was mainly due to Gastrointestinal (GI) bleeding and Hepatic Encephalopathy (HE). Overall mortality was 27%. Age and sex showed no statistical difference between survivors and non survivors. Significantly higher mean values were observed for all models among individuals who died compared to survivors. MELD-Na was the most specific compared to the other scores. MELD-Na was highly predictive of mortality at an optimized cut-off value of 20.4 (AURC=0.789±0.03-CI 95%=0.711-0.865) while original MELD was highly predictive of mortality at an optimized cut-off value of 17.4 (AURC=0.678±0.01-CI 95%=0.613-0.682) denoting the importance of adding serum sodium to the original MELD. INR, serum creatinine, bilirubin, white blood cells count and hyponatremia were significantly higher in non survivors compared to survivors, while hypoalbuminemia showed no statistical difference. The advent of Hepatorenal Syndrome (HRS) and Spontaneous Bacterial Peritonitis (SBP) carried worse prognosis. Hyponatremia and number of transfused blood bags were additional independent predictors of mortality.

CONCLUSION

In cirrhosis of liver, due to HCV infection, patients who died during their ICU stay displayed significantly higher values on all prognostic scores at admission. The addition of sodium to MELD score greatly improves the predictive accuracy of mortality. MELD-Na showed the highest predictive value of all scores.

Albumin-bilirubin (ALBI) score at admission predicts possible outcomes in patients with acute-on-chronic liver failure

The albumin-bilirubin (ALBI) score is a new model for assessing the severity of liver dysfunction. The purpose of the present study is to investigate the prognostic value of the ALBI score in predicting the 3-month outcome of patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure (AoCLF).This study included 84 patients with HBV-AoCLF, 56 chronic hepatitis B (CHB) patients, and 48 healthy controls (HCs). The virological parameters and biochemical examination of blood were obtained after 12 hours of fasting. The follow-up of AoCLF patients lasted for at least 3 months, and the relationships between the prognosis and ALBI score were analyzed.A significantly higher ALBI score was detected in AoCLF patients than in the HC and CHB groups (both P = .001). The ALBI score was positively correlated with the model of the end-stage liver disease (MELD) score and Child-Pugh score. Moreover, ALBI scores were higher among non-survivors than survivors in AoCLF patients. Multivariate analysis suggested that both the ALBI and MELD scores were independent predictors of the 3-month mortality in AoCLF patients (P < .001).A high ALBI score measured at admission may be used as a predictor for the 3-month mortality rate in patients with HBV-AoCLF.

Adoption of Sorafenib for the Treatment of Advanced-Stage Hepatocellular Carcinoma in Oncology Practices in the United States

BACKGROUND

The adoption of sorafenib into oncology practice as a first-line systemic treatment for advanced hepatocellular carcinoma (HCC) is not well understood. We examined sorafenib use since Food and Drug Administration (FDA) approval in 2007 and associated survival for individuals diagnosed with advanced HCC, conducting a population-based evaluation of treatment patterns and outcomes for this newly approved drug in the US over time.

METHODS

We identified individuals diagnosed with Barcelona Clinic Liver Cancer Stage C from the 2007 and 2012 National Cancer Institute Patterns of Care study. We examined trends in use as well as patient and clinical factors associated with receiving sorafenib using multivariate logistic regression analysis. We then evaluated the association between sorafenib use and overall hazard of death using multivariate Cox proportional hazards regression.

RESULTS

Among 550 individuals diagnosed with advanced HCC, we found no significant increase in the proportion of patients treated with sorafenib from 2007 to 2012 (26.3 vs. 30.4%). After adjusting for patient and clinical characteristics, non-Hispanic Blacks (compared to non-Hispanic Whites) and those with a lower Child-Pugh score remained more likely to receive sorafenib. Individuals receiving systemic chemotherapy only, radiation therapy only, or no treatment at all experienced a higher risk of death than those treated with sorafenib, while those receiving a transplant experienced a lower risk of death.

CONCLUSIONS

Sorafenib has not been widely adopted into oncology practice since FDA approval for advanced HCC. Few factors apart from Child-Pugh score and race/ethnicity predict sorafenib use in clinical practice, although sorafenib treatment is associated with a lower risk of death.

Randomized clinical trial of landiolol hydrochloride for the prevention of atrial fibrillation and postoperative complications after oesophagectomy for cancer

Background

Atrial fibrillation is common after oesophageal surgery. The aim of this study was to evaluate whether landiolol hydrochloride was effective and safe in the prevention of atrial fibrillation after oesophagectomy, and to see whether a reduction in incidence of atrial fibrillation would reduce other postoperative complications.

Methods

This single-centre study enrolled patients scheduled for transthoracic oesophagectomy in a randomized, double-blind, placebo-controlled trial between March 2013 and January 2016. Enrolled patients were randomized with a 1 : 1 parallel allocation ratio to either landiolol prophylaxis or placebo. The primary endpoint was the occurrence of atrial fibrillation after oesophagectomy. Secondary endpoints were incidence of postoperative complications, and effects on haemodynamic and inflammatory indices.

Results

One hundred patients were enrolled, 50 in each group. Postoperative atrial fibrillation occurred in 15 patients (30 per cent) receiving placebo versus five (10 per cent) receiving landiolol (P = 0·012). The overall incidence of postoperative complications was significantly lower in the landiolol group (P = 0·046). In the landiolol group, postoperative heart rate was suppressed effectively, but the decrease in BP was not harmful. The interleukin 6 level was significantly lower on days 3 and 5 after surgery in the landiolol group (P = 0·001 and P = 0·002 respectively).

Conclusion

Landiolol was effective and safe in preventing atrial fibrillation after oesophagectomy. Registration number: UMIN000010648 (http://www.umin.ac.jp/ctr/).

Usefulness of albumin-bilirubin grade for evaluation of long-term prognosis for hepatitis B-related cirrhosis

Long-term prognosis varies widely among patients with hepatitis B virus (HBV)-related liver cirrhosis. Our study aimed to investigate the applicability of albumin-bilirubin (ALBI), Child-Pugh and model for end-stage liver disease (MELD) scores to the long-term prognosis prediction of HBV-related cirrhosis. Patients diagnosed with HBV-associated cirrhosis from the First Affiliated Hospital of Wenzhou Medical University between January 2010 and December 2015 were enrolled in this study. The patients were followed up every 3 months. The prognostic performance of ALBI in long-term outcome prediction for HBV-related cirrhosis was compared with Child-Pugh and MELD scores using time-dependent receiver operating characteristic curve (tdROC) and decision curve analysis. A total of 806 patients were included in our study with 275 (34.1%) deceased during the follow-up. Multivariate Cox regression analysis showed that ALBI grade was an independent predictor associated with mortality. The tdROC analysis showed that ALBI score (0.787, 0.830 and 0.833) was superior to MELD (0.693, P=.003; 0.717, P<.001; 0.744, P<.001) and Child-Pugh score (0.641, P<.001; 0.649, P<.001; 0.657, P<.001) for predicting 1-year, 2-year and 3-year mortality. Additionally, decision curves also got the similar results. In addition, patients with lower ALBI score had a longer life expectancy, even among patients within the same Child-Pugh class. Thus, ALBI score was effective in predicting the long-term prognosis for patients with HBV-related cirrhosis and more accurate than Child-Pugh and MELD scores.

Evaluating segmental liver function using T1 mapping on Gd-EOB-DTPA-enhanced MRI with a 3.0 Tesla

Background

Assessing the liver function provides valuable information to evaluate surgical risk and plan accordingly. Current studies focus on whole liver function evaluation. However, assessment of segmental liver function is equally important in the clinical practice. The purpose of this study was to investigate whether Gd-EOB-DTPA-enhanced MRI can evaluate the liver function of each segment by using T1 mapping at 3 Tesla MRI.

Methods

One hundred three patients were classified into one of 4 groups: a normal liver function (NLF) group (n = 38), a liver cirrhosis with Child-Pugh A (LCA) group (n = 33), a liver cirrhosis with Child-Pugh B (LCB) group (n = 21), and a liver cirrhosis with Child-Pugh C (LCC) group (n = 11). All patients underwent Gd-EOB-DTPA-enhanced MRI scans. T1 relaxation times were measured on the liver superimposing T1 mapping images. Reduction rate (△%) of T1 relaxation time of the liver parenchyma were calculated.

Results

After 20 min of Gd-EOB-DTPA enhancement, the T1 relaxation time of all liver segments in the LCC group were different from those in all the other groups, and more liver segments from the LCB and LCA groups different from the NLF group (p < 0.05). For the LCB group, the areas under the receiver operating characteristic curves (AUCs) of different liver segments for hepatobiliary phase (HBP) were 0.654-0.904 on T1 relaxation time, and 0.709-0.905 on △%. For the LCC group, the AUCs of different liver segments for HBP were 0.842–0.997 on T1 relaxation time, and 0.887–0.990 on △%.

Conclusions

For LCB patients, segmental liver function evaluation is possible using Gd-EOB-DTPA-enhanced MRI T1 mapping. For LCC patients, all liver segments can be used to evaluate liver function and both T1 relaxation time and the △% of T1 relaxation time have good diagnostic performance.
