Biomarker for cardiorenal syndrome risk in patients with liver cirrhosis and type 2 diabetes in Saudi Arabia

OBJECTIVES

To evaluate the correlation between different attributes, levels of biomarkers, and the probability of developing cardiorenal syndrome (CRS) in patients who have been diagnosed with type 2 diabetes mellitus (T2DM) and liver cirrhosis (LC). The hypothesis suggests that liver illness may be linked to renal impairment, cardiac dysfunction, and the development of cardiorenal syndrome METHODS: The current study retrospectively assessed the medical records of patients who had LC and T2DM diagnoses and were hospitalized at Al Madina Al Munwara hospitals in 2022 and 2023.

RESULTS

This research investigated T2DM patients with physician-confirmed to have LC. Poor glycemic control is indicated by high blood glucose and glycated hemoglobin (HbA1c) readings in research participants. High blood pressure, atherogenic plasma indicator (AIP), and obesity plagued most of these individuals. High creatinine, moderate estimated Glomerular Filtration Rate (eGFR) decline, and a modest urinary albumin-to-creatinine (UACR) rise were the most prevalent variables in LC and T2DM patients. Cardiorenal syndrome risk factors, including elevated blood pressure, triglyceride levels, body mass index (BMI), and high-sensitivity C-reactive protein (hs-CRP) concentrations, were identified through logistic regression. It has been demonstrated that the prevalence of these risk factors increases with age; women may be at a greater risk for developing CRS. Specific biomarker evaluations classified 108 (22.6%) LC and T2DM patients at high risk for chronic kidney disease (CKD), 100 (20%) at risk for cardiovascular disease (CVD), and 91 (18.2%) at risk for CRS.

CONCLUSION

The current assessment included 500 patients with T2DM and LC. The risk factors for CRS identified in this study included elevated cholesterol and triglyceride levels, high BMI, and elevated blood pressure, with age being a significant factor, particularly in female patients. Early identification of these characteristics in patients with LC and T2DM could aid in mitigating the progression of chronic illnesses and their associated complications.

External validation of the modified CTP score based on ammonia to predict survival in patients with cirrhosis after TIPS placement

This study aimed to perform the first external validation of the modified Child-Turcotte-Pugh score based on plasma ammonia (aCTP) and compare it with other risk scoring systems to predict survival in patients with cirrhosis after transjugular intrahepatic portosystemic shunt (TIPS) placement. We retrospectively reviewed 473 patients from three cohorts between January 2016 and June 2022 and compared the aCTP score with the Child-Turcotte-Pugh (CTP) score, albumin-bilirubin (ALBI), model for end-stage liver disease (MELD) and sodium MELD (MELD-Na) in predicting transplant-free survival by the concordance index (C-index), area under the receiver operating characteristic curve, calibration plot, and decision curve analysis (DCA) curve. The median follow-up time was 29 months, during which a total of 62 (20.74%) patients died or underwent liver transplantation. The survival curves for the three aCTP grades differed significantly. Patients with aCTP grade C had a shorter expected lifespan than patients with aCTP grades A and B (P < 0.0001). The aCTP score showed the best discriminative performance using the C-index compared with other scores at each time point during follow-up, it also showed better calibration in the calibration plot and the lowest Brier scores, and it also showed a higher net benefit than the other scores in the DCA curve. The aCTP score outperformed the other risk scores in predicting survival after TIPS placement in patients with cirrhosis and may be useful for risk stratification and survival prediction.

Combination of Model for End-Stage Liver Disease (MELD) and Sarcopenia predicts mortality after transjugular intrahepatic portosystemic shunt (TIPS)

TIPS is the most effective treatment for portal hypertension. Patient selection remains important to achieving optimal post-TIPS outcomes. The study evaluates 1-year mortality factors in cirrhotic patients receiving TIPS.

METHODS

87 cirrhotic patients received a TIPS between 2015 - 2021. Predictors of 1-year and overall mortality were assessed by estimating cumulative incidence functions and Grey's test to adjust for liver transplantation as a risk competing with mortality. Variables with p < 0.05 were checked for collinearity and included in the multivariate Cox proportional hazards model. Model discrimination was evaluated by calculating the area under the ROC curve.

RESULTS

87 patients were included (68% men; 22% ≥70 years). ALD was the primary cirrhosis cause. Most patients were Child-Pugh class B, MELD-Na score was 13.6 ± 6.0 points. The most frequent indication for TIPS was bleeding (51.7%), followed by refractory ascites (42.5%). The variables positively associated with mortality in univariate analysis were ascites, clinically overt sarcopenia and MELD-Na score, while ongoing nutritional supplementation improved survival. In the multivariate analysis, only clinically overt sarcopenia and MELD-Na score remained independently associated with mortality. A MELD-Na/sarcopenia model demonstrated a good discrimination, AUROC: 0.86 (95% CI 0.77 - 0.95).

CONCLUSION

MELD-Na score, and sarcopenia were significantly associated with 1-year survival in cirrhotic patients who received TIPS.

A modified model for predicting mortality after transjugular intrahepatic portosystemic shunt: A multicentre study

BACKGROUND AND AIMS

The transjugular intrahepatic portosystemic shunt has controversial survival benefits; thus, patient screening should be performed preoperatively. In this study, we aimed to develop a model to predict post-transjugular intrahepatic portosystemic shunt mortality to aid clinical decision making.

METHODS

A total of 811 patients undergoing transjugular intrahepatic portosystemic shunt from five hospitals were divided into the training and external validation data sets. A modified prediction model of post-transjugular intrahepatic portosystemic shunt mortality (ModelMT ) was built after performing logistic regression. To verify the improved performance of ModelMT , we compared it with seven previous models, both in discrimination and calibration. Furthermore, patients were stratified into low-, medium-, high- and extremely high-risk subgroups.

RESULTS

ModelMT demonstrated a satisfying predictive efficiency in both discrimination and calibration, with an area under the curve of .875 in the training set and .852 in the validation set. Compared to previous models (ALBI, BILI-PLT, MELD-Na, MOTS, FIPS, MELD, CLIF-C AD), ModelMT showed superior performance in discrimination by statistical difference in the Delong test, net reclassification improvement and integrated discrimination improvement (all p < .050). Similar results were observed in calibration. Low-, medium-, high- and extremely high-risk groups were defined by scores of ≤160, 160-180, 180-200 and >200, respectively. To facilitate future clinical application, we also built an applet for ModelMT .

CONCLUSIONS

We successfully developed a predictive model with improved performance to assist in decision making for transjugular intrahepatic portosystemic shunt according to survival benefits.

Mac-2-Binding Protein Glycosylation Isomer to Albumin Ratio Predicts Bacterial Infections in Cirrhotic Patients

INTRODUCTION

Mac-2-binding protein glycosylation isomer (M2BPGi) is a novel biomarker for liver fibrosis, but little is known about its role in cirrhosis-associated clinical outcomes. This study aimed to investigate the predictive role of M2BPGi in cirrhosis-associated complications.

METHODS

One hundred and forty-nine cirrhotic patients were retrospectively enrolled. Patients were followed up for 1 year, and cirrhosis-associated clinical events were recorded. Receiver operating characteristic curve (ROC) analysis was used to establish the values of the predictive models for cirrhotic outcomes, and Cox proportional hazards regression models were used to identify predictors of clinical outcomes.

RESULTS

Sixty (40.3%) patients experienced cirrhosis-associated clinical events and had higher M2BPGi levels compared to those without events (8.7 vs. 5.1 cutoff index, p < 0.001). The most common cirrhosis-associated complications were bacterial infections (24.2%). On ROC analysis, M2BPGi to albumin ratio (M2BPGi/albumin) had comparable discriminant abilities for all cirrhosis-associated events (area under the ROC curve [AUC] = 0.74) compared with M2BPGi, Child-Pugh, model for end-stage liver disease, albumin-bilirubin scores, and neutrophil-to-lymphocyte ratio and was superior to M2BPGi alone for all bacterial infectious events (AUC = 0.80). Cox regression analysis revealed that the M2BPGi/albumin, but not M2BPGi alone, independently predicted all cirrhosis-associated events (hazard ratio [HR] = 1.34, p = 0.038) and all bacterial infectious events (HR = 1.51, p = 0.011) within 1 year. However, M2BPGi/albumin did not predict other cirrhotic complications and transplant-free survival.

DISCUSSION/CONCLUSION

M2BPGi/albumin might serve as a potential prognostic indicator for patients with cirrhosis, particularly for predicting bacterial infections.

Plug-Assisted Retrograde Transvenous Obliteration for the Treatment of Duodenal Variceal Bleeding - A Case Report and Literature Review

Duodenal varices are uncommon complications of portal hypertension. Although duodenal variceal bleeding is infrequent, it is a life-threatening condition with a high mortality rate. Non-surgical methods for duodenal variceal bleeding include endoscopic band ligation, endoscopic sclerotherapy, transjugular intrahepatic portosystemic shunt, and retrograde transvenous obliteration. On the other hand, an optimal treatment strategy for this rare condition has not been established. A 38-year-old male with a history of alcoholic liver cirrhosis presented with hematemesis. An emergency esophagogastroduodenoscopy (EGD) revealed large, multiple varices in the second portion of the duodenum, and plug-assisted retrograde transvenous obliteration (PARTO) was performed accordingly. Gastrointestinal bleeding was resolved after the procedure. Follow-up EGD conducted after 11 weeks revealed complete obliteration of the previously observed duodenal varices. PARTO may be considered a viable option for treating duodenal variceal bleeding.

Predictive Accuracy Comparison of Prognostic Scoring Systems for Survival in Patients Undergoing TIPS Placement: A Systematic Review and Meta-analysis

RATIONALE AND OBJECTIVES

This meta-analysis aimed to evaluate the performance of different risk assessment models (RAMs) for survival after Transjugular Intrahepatic Portosystemic Shunt (TIPS) in patients with cirrhotic portal hypertension.

MATERIALS AND METHODS

A systematic search of PubMed, WOS, Embase, Cochrane, and CNKI from inception to February 2023 was conducted. We comprehensively reviewed and aggregated data from numerous studies covering prevalent RAMs such as Child-Turcotte-Pugh, the Model for End-Stage Liver Disease (MELD), MELD-Sodium (MELD-Na), the Freiburg Index of Post-TIPS Survival (FIPS), Bilirubin-platelet, Chronic Liver Failure Consortium Acute Decompensation score, and Albumin-Bilirubin grade across different timeframes. For this study, short-term is defined as outcomes within a year while long-term refers to outcomes beyond one year. The area under the receiver operating characteristic (AUC) curve or Concordance Statistics was chosen as the metric to assess predictive capacity for mortality outcomes across six predetermined time intervals. Mean effect sizes at various time points were determined using robust variance estimation.

RESULTS

MELD consistently stood out as a primary short-term survival predictor, particularly for 1 month (± 2 weeks) (AUC: 0.72) and 3 months of (± 1 month) survival (AUC: 0.72). MELD-Na showed the best long-term predictive ability, with an AUC of 0.70 at 3.5 years (± 1.5 years). FIPS performed well for 6 months of (± 2 months) survival (AUC: 0.68) and overall transplant-free survival (AUC: 0.75). Efficacy nuances were observed in RAMs when applied to particular subgroups. Meta-regression emphasized the potential predictor overlaps in models like MELD and FIPS.

CONCLUSION

This meta-analysis underscores the MELD score as the premier predictor for short-term survival following TIPS. Meanwhile, the FIPS score and MELD-Na model exhibit potential in forecasting long-term outcomes. The study accentuates the significance of RAM selection for enhancing patient outcomes and advocates for additional research to corroborate these findings and fine-tune risk assessment in TIPS.

DNA Methylation Biomarkers as Prediction Tools for Therapeutic Response and Prognosis in Intermediate-Stage Hepatocellular Carcinoma

INTRODUCTION

Alfa-fetoprotein (AFP), as the main serum tumor marker of hepatocellular carcinoma (HCC), is limited in terms of specificity and ability to predict outcomes. This study investigated the clinical utility of DNA methylation biomarkers to predict therapeutic responses and prognosis in intermediate-stage HCC.

METHODS

This study enrolled 72 patients with intermediate-stage HCC who underwent locoregional therapy (LRT) between 2020 and 2021. The immediate therapeutic response and disease status during a two-year follow-up were recorded. Analysis was performed on 10 selected DNA methylation biomarkers via pyrosequencing analysis of plasma collected before and after LRT.

RESULTS

Analysis was performed on 53 patients with complete responses and 19 patients with disease progression after LRT. The mean follow-up duration was 2.4 ± 0.6 years. A methylation prediction model for tumor response (MMTR) and a methylation prediction model for early progression (MMEP) were constructed. The area under the curve (AUC) for sensitivity and specificity of MMTR was 0.79 for complete response and 0.759 for overall survival. The corresponding AUCs for sensitivity and specificity of AFP and protein induced by vitamin K absence-II (PIVKA-II) were 0.717 and 0.708, respectively. Note that the MMTR index was the only significant predictor in multivariate analysis. The AUC for sensitivity and specificity of the MMEP in predicting early progression was 0.79. The corresponding AUCs for sensitivity and specificity of AFP and PIVKA-II were 0.758 and 0.714, respectively. Multivariate analysis revealed that platelet count, beyond up-to-7 criteria, and the MMEP index were strongly correlated with early tumor progression. Combining the indexes and serum markers further improved the predictive accuracy (AUC = 0.922). Multivariate analysis revealed the MMEP index was the only independent risk factor for overall survival.

DISCUSSION/CONCLUSIONS

This study indicates that these methylation markers could potentially outperform current serum markers in terms of accuracy and reliability in assessing treatment response and predicting outcomes. Combining methylation markers and serum markers further improved predictive accuracy, indicating that a multi-marker approach may be more effective in clinical practice. These findings suggest that DNA methylation biomarkers may be a useful tool for managing intermediate-stage HCC patients and guiding personalized treatment, particularly for those who are at high risk for close surveillance or adjuvant treatment after LRT.

The Added Value of Sarcopenia on Existing Risk Scores to Predict Mortality after TIPS Placement: A Multicenter Study

RATIONALE AND OBJECTIVES

Multiple prognostic scores have been applied for predicting survival after TIPS placement. The aim was to evaluate the added value of sarcopenia on existing risk scores and develop a sarcopenia-based scoring system for survival prediction and risk stratification.

MATERIALS AND METHODS

In the derivation cohort of 386 cirrhotic patients undergoing TIPS, five risk scores (Child-Pugh, MELD, MELD-Na, MELD 3.0, and FIPS) were compared for prediction of short- and long-term mortality after TIPS. Sarcopenia was diagnosed based on the L3 skeletal muscle index and was incorporated into existing scores to assess its added value. A novel sarcopenia-based score was developed and externally validated in an independent cohort of 198 patients undergoing TIPS.

RESULTS

Among existing scores, the FIPS score showed the highest discrimination (c-index: 0.756-0.783) and calibration (Brier score: 0.059-0.127). Besides, the FIPS score was significantly associated with the severity of baseline sarcopenia and reversal of sarcopenia after TIPS. The inclusion of sarcopenia improved discrimination of existing scores in different degrees and sarcopenia could stratify the low-risk categories deemed by these scores. A FIPS-sarcopenia score was developed, showing superior discrimination over existing scores (c-index: 0.777-0.804 in the derivation cohort, 0.738-0.788 in the validation cohort). With a determined cutoff of 0.8, this score allowed for the identification of two prognostic subgroups with distinct prognoses.

CONCLUSION

FIPS score was highly correlated with the severity of sarcopenia and sarcopenia reversal after TIPS, and sarcopenia could improve the prognostic ability of existing scores. A FIPS-sarcopenia score was developed and validated, showing improved survival prediction and risk stratification.

Frailty as a risk-stratification tool in patients undergoing transjugular intrahepatic portosystemic shunt (TIPS)

Objectives

The concept of frailty has gained importance, especially in patients with liver disease. Our study systematically investigated the effect of frailty on post-procedural outcomes in patients undergoing transjugular intrahepatic portosystemic shunt (TIPS).

Methods

We used National Inpatient Sample(NIS) 2016-2019 data to identify patients who underwent TIPS. Hospital frailty risk score (HFRS) was used to classify patients as frail (HFRS>=5) and non-frail (HFRS<5). The relationship between frailty and outcomes such as death, post-procedural shock, non-home discharge, length of stay (LOS), post-procedural LOS, and total hospitalization charges (THC) was assessed.

Results

A total of 13,700 patients underwent TIPS during 2016-2019. Of them, 5,995 (43.76%) patients were frail, while 7,705 (56.24%) were non-frail. There were no significant differences between the two groups based on age, gender, race, insurance, and income. Frail patients had higher mortality (15.18% vs. 2.07%, p<0.001), a higher incidence of non-home discharge (53.38% vs. 19.08%, p<0.001), a longer overall LOS (12.5 days vs. 3.35,p<0.001), longer post-procedural stay (8.2 days vs. 3.4 days, p<0.001), and higher THC ($240,746.7 vs. $121,763.1, p<0.001) compared to the non-frail patients. On multivariate analysis, frail patients had a statistically significant higher risk of mortality (aOR-3.22, 95% CI-1.98- 5.00, p<0.001).

Conclusion

Frailty assessment can be beneficial in risk stratification in patients undergoing TIPS.

MELD 3.0 Score for Predicting Survival in Patients with Cirrhosis After Transjugular Intrahepatic Portosystemic Shunt Creation

BACKGROUND AND AIMS

The selection of appropriate candidates for transjugular intrahepatic portosystemic shunt (TIPS) is important and challenging. To validate the Model for End-Stage Liver Disease (MELD) 3.0 in predicting mortality in patients with cirrhosis after TIPS creation.

METHODS

A total of 855 consecutive patients with cirrhosis from December 2011 to October 2019 who underwent TIPS placement were retrospectively reviewed. The prognostic value of the MELD 3.0, MELD, MELD-Na, Child-Pugh and FIPS score was assessed using Harrell's C concordance index (c-index). The Hosmer-Lemeshow test was used to test the goodness of fit of all models and the calibration plot was drawn.

RESULTS

The c-index of the MELD 3.0 in predicting 3-month mortality was 0.727 (0.645-0.808), which were significantly superior to the MELD (0.663 [0.565-0.761]; P = 0.015), MELD-Na (0.672 [0.577-0.768]; P = 0.008) and FIPS (0.582 [0.477-0.687]; P = 0.015). The Child-Pugh score reached c-indices of 0.754 (0.673-0.835), 0.720 (0.649-0.792), 0.705 (0.643-0.766) and 0.665 (0.614-0.716) for 3-month, 6-month, 1-year, and 2-year mortality, respectively, which seems comparable to MELD 3.0. A MELD 3.0 of 14 could be used as a cut-off point for discriminating between high- and low-risk patients. The MELD 3.0 could stratify patients with Child-Pugh grade B (log-rank P < 0.001). The Child-Pugh score could stratify patients defined as low risk by MELD 3.0 (log-rank P < 0.001).

CONCLUSIONS

The MELD 3.0 was significantly superior to the MELD, MELD-Na and FIPS scores in predicting mortality in patients with cirrhosis after TIPS creation.

The Risk of Endoscopy-Related Bleeding in Patients with Liver Cirrhosis: A Retrospective Study

Background and Objectives: The risk of bleeding after endoscopic procedures in patients with liver cirrhosis remains unclear because of secondary blood coagulation disorders. In this study, we used various indices to evaluate the risk of bleeding in patients with cirrhosis. Materials and Methods: Patients with liver cirrhosis aged ≥18 years who underwent endoscopic interventions at Kyung Hee University Hospital at Gangdong between February 2007 and September 2021 were included. Clinical information, including demographic data, laboratory results, the presence of cirrhosis complications, and the degree of fibrosis, was checked and evaluated based on medical records. Results: A total of 101 patients with cirrhosis were analyzed. A total of 16 of the 101 patients (15.8%) experienced bleeding after the endoscopic procedure. One patient (0.99%) presented with spurting, while the others presented with mild oozing. All patients underwent hemostatic procedures using hemoclips. The presence of a varix significantly increased post-endoscopic bleeding (p = 0.03). Patients with FIB > 3.25 showed a statistically significant bleeding tendency (p = 0.00). Conclusions: There was no significant difference in bleeding risk according to the platelet count, prothrombin time, Child−Pugh score, and model for end-stage liver disease (MELD). Considering the degree of liver fibrosis and the invasiveness of the planned procedure, most endoscopic procedures can be performed safely but should be further evaluated in a cohort with a larger sample size.

Nomogram-based development and evaluation for predictions of 30-day and 1-year survival in patients with spontaneously ruptured hepatocellular carcinoma

Background

Accurately predicting the prognosis of patients with spontaneously ruptured hepatocellular carcinoma (HCC) is crucial for effective clinical management. The aim of the present study was to establish and evaluate prediction models for 30-day and 1-year survival in patients with spontaneously ruptured HCC.

Methods

A total of 118 patients with spontaneous rupture HCC were enrolled. Univariate and multivariate analyses were performed using logistic-regression model and Cox proportional-hazard model. The identified indicators were used to establish prediction models, the performance of which we compared with those of commonly used liver disease scoring models. The survival possibilities of different risk categories were calculated using the newly developed models.

Results

Largest tumor size (LTS), serum albumin (ALB), total bilirubin (TBil), and serum creatinine were identified as independent predictors, which were used to establish a 30-day survival prediction model. LTS, BCLC staging, ALB, TBil, hepatectomy at rupture, and TACE during follow-up were identified as independent predictors of 1-year survival model. The 30-day survival model had sensitivity of 79.3%, specificity of 87.1%, and an AUC of 0.879, exhibiting better predictive performance than scores for Chronic Liver Failure Consortium Acute Decompensation score (CLIF-C ADs) and Model for End-stage Liver Disease (MELD). The 1-year survival model had sensitivity of 66.7%, specificity of 94.6%, and an AUC of 0.835, showing better predictive performance than Albumin–Bilirubin (ALBI), Child–Pugh, CLIF-C ADs, and MELD. After stratification, survival possibilities were 90.9 and 21.1% in low- and high-risk groups within 30 days, respectively, and 43.90, 4.35%, and 0 in low-, intermediate-, and high-risk groups at 1 year, respectively.

Conclusions

The established models exhibited good performance in predicting both 30-day and 1-year survival in patients with spontaneously ruptured HCC.

Validating the prognostic value of Freiburg index of posttransjugular intrahepatic portosystemic shunt survival score and classic scores in Chinese patients with implantation of transjugular intrahepatic portosystemic shunt

BACKGROUND AND AIMS

It is important and challenging to evaluate the survival of cirrhotic patients undergoing transjugular intrahepatic portosystemic shunt (TIPS). We aimed to validate the Freiburg index of post-TIPS survival (FIPS) score and classic scores for predicting mortality in Chinese patients after TIPS creation.

METHODS

A total of 709 consecutive patients with cirrhosis from December 2011 to July 2018 who underwent TIPS placement were retrospectively reviewed. The prognostic value of the FIPS score, the model for end-stage liver disease (MELD) score, Child-Pugh score and Chronic Liver Failure Consortium Acute Decompensation score was validated with the receiver operating characteristic (ROC) curve and DeLong et al. test.

RESULTS

The MELD-Na score was superior to the FIPS score in predicting 1-month mortality [AUROC, 0.727 (0.692-0.759) vs. 0.588 (0.551-0.625); P = 0.048]. The MELD and MELD-Na scores were significant superior to the FIPS score in predicting 3-month mortality [AUROC, 0.730 (0.696-0.762) vs. 0.598 (0.561-0.634); P = 0.044 and 0.740 (0.706-0.772) vs. 0.598 (0.561-0.634); P = 0.028]. Subgroup analyses revealed that Child-Pugh score was better than FIPS score in predicting 3-month mortality [AUROC, 0.797 (0.745-0.843) vs. 0.578 (0.517-0.637); P = 0.049] in nonviral cirrhosis group.

CONCLUSION

Classic scores still had good risk stratification and predictive ability of post-TIPS mortality. The FIPS score was not superior to the classic scores in the current Chinese cohort. The MELD and MELD-Na scores were significantly superior to the FIPS score in predicting 3-month mortality.

External Validation of the FIPS Score for Post-TIPS Mortality in a National Veterans Affairs Cohort

BACKGROUND

The Freiburg index of post-TIPS survival (FIPS) score was recently demonstrated to improve prediction of post-TIPS mortality relative to existing standards. As this score was derived from a German cohort over an extended time period, it is unclear if performance will translate well to other settings. This study aimed to externally validate the FIPS score in a large Veterans Affairs (VA) cohort over two separate eras of TIPS-related care.

METHODS

This was a retrospective cohort study of patients with cirrhosis who underwent TIPS placement in the VA from 2008 to 2020. Cox regression models for post-TIPS survival were constructed using FIPS, MELD, MELD-Na, or CTP scores as predictors. Discrimination (Harrell's C) and calibration (joint tests of calibration curve slope and intercept) were evaluated for each score. A stratified analysis was performed for time periods between 2008-2013 and 2014-2020.

RESULTS

The cohort of 1,274 patients was 97.3% male with mean age 60.9 years and mean MELD-Na 14. The FIPS score demonstrated the highest overall discrimination versus MELD, MELD-Na, and CTP (0.634 vs. 0.585, 0.626, 0.612, respectively). However, in the modern treatment era (2014-2020), the FIPS score performed similarly to MELD-Na. Additionally, the FIPS score demonstrated poor calibration at one-month and six-month post-TIPS timepoints (joint p = 0.04 and 0.004, respectively). MELD, MELD-Na, and CTP were well-calibrated at each timepoint (each joint p > 0.05).

CONCLUSION

The FIPS score performed similarly to MELD-Na in the modern TIPS treatment era and demonstrated regions of poor calibration. Future models derived with contemporary data may improve prediction of post-TIPS mortality.

A comprehensive review of prognostic scoring systems to predict survival after transjugular intrahepatic portosystemic shunt placement

Patient prognosis after transjugular intrahepatic portosystemic shunt (TIPS) placement is relatively poor and highly heterogeneous; therefore, a prognostic scoring system is essential for survival prediction and risk stratification. Conventional scores include the Child–Turcotte–Pugh (CTP) and model for end‐stage liver disease (MELD) scores. The CTP score was created empirically and displayed a high correlation with post‐TIPS survival. However, the inclusion of subjective parameters and the use of discrete cut‐offs limit its utility. The advantages of the MELD score include its statistical validation and objective and readily available predictors that contribute to its broad application in clinical practice to predict post‐TIPS outcomes. In addition, multiple modifications of the MELD score, by incorporating additional predictors (e.g., MELD‐Sodium and MELD‐Sarcopenia scores), adjusting coefficients (recalibrated MELD score), or combined (MELD 3.0), have been proposed to improve the prognostic ability of the standard MELD score. Despite several updates to conventional scores, a prognostic score has been proposed (based on contemporary data) specifically for outcome prediction after TIPS placement. However, this novel score (the Freiburg index of post‐TIPS survival, FIPS) exhibited inconsistent discrimination in external validation studies, and its superiority over conventional scores remains undetermined. Additionally, several tools display potential for application in specific TIPS indications (e.g., bilirubin‐platelet grade for refractory ascites), and biomarkers of systemic inflammation, nutritional status, liver disease progression, and cardiac decompensation may provide additional value, but require further validation. Future studies should consider the effect of TIPS placement when exploring predictors, as TIPS is a pathophysiological approach that substantially alters systemic hemodynamics and ameliorates bacterial translocation and malnutrition.

Tumor burden score as a new prognostic surrogate in patients with hepatocellular carcinoma undergoing radiofrequency ablation: role of albumin-bilirubin (ALBI) grade vs easy ALBI grade

INTRODUCTION

Tumor burden score (TBS) was proposed to represent tumor burden in solid tumors, including hepatocellular carcinoma (HCC). The prognostic role of TBS in HCC patients in relation to recently introduced liver reserve markers, albumin-bilirubin (ALBI) grade, and easy (EZ)-ALBI grade, is unclear. We aimed to investigate the feasibility of TBS in HCC patients undergoing radiofrequency ablation (RFA).

RESEARCH DESIGN AND METHODS

A total of 576 treatment-naïve patients with HCC undergoing RFA were analyzed. The multivariate Cox analysis was used to identify independent predictors associated with tumor recurrence and long-term survival.

RESULTS

Patients with high TBS had increased risk of tumor recurrence and mortality compared with those with low TBS. The Cox analysis showed that serum ɑ-fetoprotein (AFP) level >20 ng/mL, medium and high TBS, ALBI grade 2 and grade 3, EZ-ALBI grade 2 and grade 3 were associated with tumor recurrence and decreased patient survival (all p <0.05). In addition, TBS can reliably stratify tumor recurrence and overall survival in different ALBI and EZ-ALBI grade groups.

CONCLUSIONS

TBS is a simple and feasible prognostic surrogate to predict tumor recurrence and survival in HCC patients undergoing RFA. Its prognostic ability remains stable in patients with variable liver functional reserve.

Prognosis factors of predicting survival in spontaneously ruptured hepatocellular carcinoma

AIM

To investigate predictors affecting survival in patients with spontaneously ruptured hepatocellular carcinoma (srHCC).

METHODS

One-hundred-and-twenty-seven patients experiencing srHCC between January 2010 and December 2020 were enrolled. The clinical features, treatments, and outcomes were reviewed. Statistics included univariate analysis, Kaplan-Meier analysis, multivariate analysis using Cox proportional hazards model and logistic regression model, and receiver operating characteristic (ROC) curve analysis.

RESULTS

Of the 127 srHCC patients, 24, 42, and 61 patients received conservative treatment, surgical treatment, and transarterial chemoembolization/embolization (TACE/TAE) treatment at HCC rupture, respectively. The largest tumor size [hazard ratio (HR) 1.127; p < 0.001], Barcelona-Clinic Liver Cancer (BCLC) stage (HR 2.184, p = 0.023), international normalized ratio (INR; HR 3.895; p = 0.012), total bilirubin level (TBil; HR 1.014; p = 0.014), TACE after rupture (compared with conservative treatment) (HR 0.549; p = 0.029), TACE/TAE and surgery at rupture, and albumin level (HR 0.949; p = 0.017) were independent predictors affecting overall survival. A survival predictive model for HCC rupture (SPHR) using these predictors was created. ROC analysis showed that the area under the curve (AUC) of the SPHR model for 30 day survival was 0.925, and the AUCs of the model for end-stage liver disease (MELD) score and Child-Pugh score for 30 day survival were 0.767 and 0.757, respectively.

CONCLUSION

The largest tumor size, advanced BCLC stage, higher INR and TBil, lower albumin, and conservative treatment were negative independent predictors for overall survival. The SPHR model may be more suitable than the MELD score and Child-Pugh score for predicting 30 day survival in srHCC.

A novel score predicts mortality after transjugular intrahepatic portosystemic shunt: MOTS - Modified TIPS Score

BACKGROUND AND AIMS

The high risk for severe shunting-related post-interventional complications demands a stringent selection of candidates for transjugular intrahepatic portosystemic shunt (TIPS). We aimed to develop a simple and reliable tool to accurately predict early post-TIPS mortality.

METHODS

144 cases of TIPS implantation were retrospectively analysed. Using univariate and multivariate Cox regression analysis of factors predicting mortality within 90 days after TIPS, a score integrating urea, international normalized ratio (INR) and bilirubin was developed. The Modified TIPS-Score (MOTS) ranges from 0 to 3 points: INR >1.6, urea >71 mg/dl and bilirubin >2.2 mg/dl account for one point each. Additionally, MOTS was tested in an external validation cohort (n = 187) and its performance was compared to existing models.

RESULTS

Modified TIPS-Score achieved a significant prognostic discrimination reflected by 90-day mortality of 8% in patients with MOTS 0-1 and 60% in patients with MOTS 2-3 (p < .001). Predictive performance (area under the curve) of MOTS was accurate (c = 0.845 [0.73-0.96], p < .001), also in patients with renal insufficiency (c = 0.830 [0.64-1.00], p = .02) and in patients with refractory ascites (c = 0.949 [0.88-1.00], p < .001), which are subgroups with particular room for improvement of post-TIPS mortality prediction. The results were reproducible in the validation cohort.

CONCLUSIONS

Modified TIPS-Score is a novel, practicable tool to predict post-TIPS mortality, that can significantly simplify clinical decision making. Its practical applicability should be further investigated.

FIB-4 and APRI as Predictive Factors for Short- and Long-Term Survival in Patients with Transjugular Intrahepatic Portosystemic Stent Shunts

(1) Background: Transjugular intrahepatic portosystemic shunt (TIPS) is a standard therapy for portal hypertension. We aimed to explore the association of established baseline scores with TIPS outcomes. (2) Methods: In total, 136 liver cirrhosis patients underwent TIPS insertion, mainly to treat refractory ascites (86%), between January 2016 and December 2019. An external validation cohort of 187 patients was chosen. (3) Results: The majority of the patients were male (62%); the median follow-up was 715 days. The baseline Child—Turcotte−Pugh stage was A in 14%, B in 75% and C in 11%. The patients’ liver-transplant-free (LTF) survival rates after 3, 12 and 24 months were 87%, 72% and 61%, respectively. In the univariate analysis, neither bilirubin, nor the international normalized ratio (INR), nor liver enzymes were associated with survival. However, both the APRI (AST-to-platelet ratio index) and the FIB-4 (fibrosis-4 score) were associated with LTF survival. For patients with FIB-4 > 3.25, the hazard ratio for mortality after 2 years was 3.952 (p < 0.0001). Liver-related clinical events were monitored for 24 months. High FIB-4 scores were predictive of liver-related events (HR = 2.404, p = 0.001). Similarly, in our validation cohort, LTF survival was correlated with the APRI and FIB-4 scores. (4) Conclusions: Well-established scores that reflect portal hypertension and biochemical disease activity predict long-term outcomes after TIPS and support clinical decisions over TIPS insertion.

Predicting death or recurrence of portal hypertension symptoms after TIPS procedures

BACKGROUND

Accurate prediction of portal hypertension recurrence after transjugular intrahepatic portosystemic shunt (TIPS) placement will improve clinical decision-making.

PURPOSE

To evaluate if perioperative variables could predict disease-free survival (DFS) in cirrhotic patients with portal hypertension (PHT) treated with TIPS.

MATERIALS AND METHODS

We recruited 206 cirrhotic patients with PHT treated with TIPS, randomly assigned to training (n = 138) and validation (n = 68) sets. We recorded 7 epidemiological, 4 clinical, and 9 radiological variables. TIPS-distal end positioning (TIPS-DEP) measured the distance between the distal end of the stent and the hepatocaval junction on contrast-enhanced CT scans. In the training set, the signature was defined as the random forest for survival algorithm achieving the lowest error rate for the prediction of DFS which was landmarked 4 weeks after the TIPS procedure. In the training set, a simple to use scoring system was derived from variables selected by the signature. The primary endpoint was to assess if TIPS-DEP was associated with DFS. The secondary endpoint was to validate the scoring system in the validation set.

RESULTS

Overall, patients with TIPS-DEP ≥ 6 mm (n = 49) had a median DFS of 24.5 months vs. 72.8 months otherwise (n = 157, p = 0.004). In the training set, the scoring system was calculated by adding age ≥ 60 years old, Child-Pugh B or C, and TIPS-DEP ≥ 6 mm (1 point each) since the signature showed high DFS probability at 6.5 months post-landmark in patients that did not meet these criteria: 86%, 80%, and 78%, respectively. The hazard ratio [95 CI] between patients determined to be low-risk (< 2 points) and high-risk (≥ 2 points) was 2.30 [1.35-3.93] (p = 0.002) in the training set and 2.01 [0.94-4.32] (p = 0.072) in the validation set.

CONCLUSION

TIPS-DEP is an actionable radiological biomarker which can be combined with age and Child-Pugh score to predict death or PHT symptom recurrence after TIPS procedure.

KEY POINTS

• TIPS-DEP measurement was the third most important but only actionable variable for predicting DFS. • TIPS-DEP < 6 mm was associated with a DFS probability of 78% at 6.5 months post-landmark. • A simple scoring system calculated using age, Child-Pugh score, and TIPS-DEP predicted DFS after TIPS.

Long-term survival prediction for transjugular intrahepatic portosystemic shunt in severe cirrhotic ascites: assessment of ten prognostic models

OBJECTIVES

Patients with severe cirrhotic ascites have poor prognosis, yet individual patient survival varies greatly. Therefore, suitable prognostic models can be helpful in clinical decision making. The aim of this study was to evaluate and compare the performance of 10 scores in predicting transplant-free survival (TFS) after transjugular intrahepatic portosystemic shunt (TIPS) in severe cirrhotic ascites.

METHODS

Two hundred eighty consecutive cirrhotic patients with severe ascites undergoing TIPS between March 2006 and December 2017 were retrospectively screened and included from nine tertiary Chinese centers, consisting of 123 patients with refractory ascites and 157 with recurrent ascites. Discriminatory ability of these models was further assessed in the whole cohort and subgroups.

RESULTS

TFS rates of all 280 patients were 75.4, 65.7, and 53.6% at 6-month, 1-year, and 2-year follow-up, respectively. Compared with other prognostic systems, the integrated model for end-stage liver disease (iMELD, incorporating serum sodium and age) showed optimal performance in predicting 6-month, 1-year, and 2-year TFS. Cutoffs were determined according to c-index and were used to stratify patients into three strata presenting significantly different TFS for short-term and long-term: iMELD < 32, ≥32 but <38 and ≥38 (log-rank P < 0.001).

CONCLUSIONS

The iMELD score proved to be the best prognostic model in predicting TFS in patients with severe cirrhotic ascites receiving TIPS. Meanwhile, the model could stratify patients in three strata to help guiding clinical practice.

Predictive potential of the MELD and Child-Turcotte-Pugh II scores for SBP in patients with cirrhosis and ascites

It is very important for patients with spontaneous bacterial peritonitis (SBP) to assess the length of survival and the risk of death, primarily because of the wide range of potential complications that can lead to multisystem organ failure and fatal outcome. The aim of this study was to determine the predictive potential of MELD and Child-Turcotte-Pugh II score for SBP in patients with cirrhosis and ascites. Material and methods: The study was designed as a prospective-analytical-observational and was conducted at the University Clinic for Gastroenterohepatology in Skopje for a period of one year. The study population included 70 hospitalized patients with established liver cirrhosis, regardless of etiology, divided into two groups, 35 patients with SBP and 35 non-SBP. Prognostic scores in patients with liver cirrhosis and ascites: MELD score, according to the formula: MELD = [(0.957 x Ln Creatinin) + (0.378 x Ln Bilirubin) + (1.12 x Ln INR) + (0.643) x 10]. The Child-Turcotte-Pugh II score includes 6 parameters: serum albumin and bilirubin, amount of ascites, degree of encephalopathy ( HE), prothrombin time (PT) and serum creatinine, and assessment of the degree of hepatic encephalopathy according to the West Haven criteria. Results: The average value of the MELD score in patients with SBP was 22.6 ± 8.27 and in non-SBP the average value was lower - 17.83±5.87. According to the Mann-Whitney U test, the difference between the mean values ​​was statistically significant for p <0.05 (z = 2.41; p = 0.015). A score of 30 to 39 was registered in 25.7% of patients with SBP, and only in 2.9% in non-SBP; the percentage difference was statistically significant for p <0.05 (Difference test, p = 0.0064 ). Patients with SBP had an average Child-Pugh score of 13.09 ± 2.48 or 100.0% C-class points. In patients with non-SBP, an average child-Pugh score of 9.63 ± 1.62 was recorded, or class B in 65.7% and class C in 34.3%. The percentage difference was statistically significant for p <0.05 (Difference test, p = 0.000000). According to the Mann-Whitney U test, the difference between the mean values ​​was statistically significant for p <0.05 (z = -5.44; p = 0.00001). ROC analysis indicated that the Child-Turcotte-Pugh II score contributed to the diagnosis of SBP - 90.7% (p = 0.000) (excellent predictor), closer to the ideal value of 1.0 and above the worst value of 0.5. ROC analysis indicated that the MELD score did not contribute to the diagnosis of SBP - 66.7% (p = 0.017) (weak predictor), closer to the worst value of 0.5. Conclusion:Our research confirmed that SBP occurs in patients with severe hepatic dysfunction calculated according to the CTP II score and MELD score. Mean value of the MELD score in patients with SBP was higher then in patients with non-SBP. On the other hand all patients with SBP had an average CTP II score, C-class points,  while the largest percentage of patients with non-SBP were class B-class points. MELD score is a weak predictor of SBP.  The best predictor for predicting SBP is the CTP II score (rank C).

Alcoholic liver disease: Current insights into cellular mechanisms

Alcoholic liver disease (ALD) due to chronic alcohol consumption is a significant global disease burden and a leading cause of mortality. Alcohol abuse induces a myriad of aberrant changes in hepatocytes at both the cellular and molecular level. Although the disease spectrum of ALD is widely recognized, the precise triggers for disease progression are still to be fully elucidated. Oxidative stress, mitochondrial dysfunction, gut dysbiosis and altered immune system response plays an important role in disease pathogenesis, triggering the activation of inflammatory pathways and apoptosis. Despite many recent clinical studies treatment options for ALD are limited, especially at the alcoholic hepatitis stage. We have therefore reviewed some of the key pathways involved in the pathogenesis of ALD and highlighted current trials for treating patients.

Transjugular intrahepatic portosystemic shunt (TIPS) placement at index portal hypertensive decompensation (anticipant TIPS) in cirrhosis and the role of early intervention in variceal bleeding and ascites

BACKGROUND

Transjugular intrahepatic portosystemic shunt (TIPS) placement improves survival in patients with refractory/recurrent acute variceal bleeding (RAVB) and refractory ascites/hydrothorax. Recently, early TIPS was shown to reduce rebleeding and improve survival compared to the conventional TIPS. We aimed to study outcomes in patients with cirrhosis undergoing TIPS at first significant portal hypertensive (PHT) decompensation (termed anticipant TIPS) compared to those undergoing TIPS for recurrent or persistent PHT complications (conventional) and compared the former to matched controls on standard medical management (SMT).

METHODS

We retrospectively analyzed the clinical, biochemical, and liver disease severity parameters and survival at baseline and post-intervention in cirrhosis patients at two major hepatobiliary intervention centers undergoing anticipant (n = 27) or conventional TIPS (n = 30) and compared the former group to matched historical controls on SMT (n = 35).

RESULTS

Baseline parameters were comparable between both the groups, including the Child-Pugh class and model for end-stage liver disease (MELD) scores. Length of stay in the intensive care unit, post-procedure admission rates, and sepsis events were higher among patients undergoing conventional TIPS (p < 0.05). Post-TIPS, at 1 year, overall and sub-grouped survivals were   better in patients undergoing anticipant TIPS. On further sub-group analysis, based on the PHT events and stratified based on Child-Pugh and MELD scores, a higher proportion of patients survived after anticipant TIPS at 1 year. Compared to SMT, patients undergoing anticipant TIPS had significantly lesser hospitalizations, recurrence of varices, and ascites at 1 year, reducing hospital visits and financial burden.

CONCLUSIONS

Anticipant TIPS at the first significant PHT event could improve liver-related events and survival compared to   standard medical management and conventional TIPS, respectively.

Serum Amyloid Beta42 Is Not Eliminated by the Cirrhotic Liver: A Pilot Study

Amyloid-beta (Aβ) deposition in the brain is the main pathological hallmark of Alzheimer disease. Peripheral clearance of Aβ may possibly also lower brain levels. Recent evidence suggested that hepatic clearance of Aβ42 is impaired in liver cirrhosis. To further test this hypothesis, serum Aβ42 was measured by ELISA in portal venous serum (PVS), systemic venous serum (SVS), and hepatic venous serum (HVS) of 20 patients with liver cirrhosis. Mean Aβ42 level was 24.7 ± 20.4 pg/mL in PVS, 21.2 ± 16.7 pg/mL in HVS, and 19.2 ± 11.7 pg/mL in SVS. Similar levels in the three blood compartments suggested that the cirrhotic liver does not clear Aβ42. Aβ42 was neither associated with the model of end-stage liver disease score nor the Child–Pugh score. Patients with abnormal creatinine or bilirubin levels or prolonged prothrombin time did not display higher Aβ42 levels. Patients with massive ascites and patients with large varices had serum Aβ42 levels similar to patients without these complications. Serum Aβ42 was negatively associated with connective tissue growth factor levels (r = −0.580, p = 0.007) and a protective role of Aβ42 in fibrogenesis was already described. Diabetic patients with liver cirrhosis had higher Aβ42 levels (p = 0.069 for PVS, p = 0.047 for HVS and p = 0.181 for SVS), which is in accordance with previous reports. Present analysis showed that the cirrhotic liver does not eliminate Aβ42. Further studies are needed to explore the association of liver cirrhosis, Aβ42 levels, and cognitive dysfunction.

Refining prediction of survival after TIPS with the novel Freiburg index of post-TIPS survival

BACKGROUND & AIMS

Transjugular intrahepatic portosystemic shunt (TIPS) implantation is an effective and safe treatment for complications of portal hypertension. Survival prediction is important in these patients as they constitute a high-risk population. Therefore, the aim of our study was to develop an alternative prognostic model for accurate survival prediction after planned TIPS implantation.

METHODS

A total of 1,871 patients with de novo TIPS implantation for ascites or secondary prophylaxis of variceal bleeding were recruited retrospectively. The study cohort was divided into a training set (80% of study patients; n = 1,496) and a validation set (20% of study patients; n = 375). Further, patients with early (preemptive) TIPS implantation due to variceal bleeding were included as another validation cohort (n = 290). Medical data and overall survival (OS) were assessed. A Cox regression model was used to create an alternative prediction model, which includes significant prognostic factors.

RESULTS

Age, bilirubin, albumin and creatinine were the most important prognostic factors. These parameters were included in a new score named the Freiburg index of post-TIPS survival (FIPS). The FIPS score was able to identify high-risk patients with a significantly reduced median survival of 5.0 (3.1-6.9) months after TIPS implantation in the training set. These results were confirmed in the validation set (median survival of 3.1 [0.9-5.3] months). The FIPS score showed better prognostic discrimination compared to the Child-Pugh, MELD, MELD-Na score and the bilirubin-platelet model. However, the FIPS score showed insufficient prognostic discrimination in patients with early TIPS implantation.

CONCLUSIONS

The FIPS score is superior to established scoring systems for the identification of high-risk patients with a worse prognosis following elective TIPS implantation.

LAY SUMMARY

Implantation of a transjugular intrahepatic portosystemic shunt (TIPS) is a safe and effective treatment for patients with cirrhosis and clinically significant portal hypertension. However, risk stratification is a major challenge in these patients as currently available scoring systems have major drawbacks. Age, bilirubin, albumin and creatinine were included in a new risk score which was named the Freiburg index of post-TIPS survival (FIPS). The FIPS score can identify patients at high risk and may guide clinical decision making.

Outcomes of curative liver resection for hepatocellular carcinoma in patients with cirrhosis

BACKGROUND

Given the poor synthetic function of cirrhotic liver, successful resection for patients with hepatocellular carcinoma (HCC) necessitates the ability to achieve resections with tumor free margins.

AIM

To validate post hepatectomy liver failure score (PHLF), compare it to other established systems and to stratify risks in patients with cirrhosis who underwent curative liver resection for HCC.

METHODS

Between December 2010 and January 2017, 120 patients underwent curative resection for HCC in patients with cirrhosis were included, the pre-operative, operative and post-operative factors were recorded to stratify patients' risks of decompensation, survival, and PHLF.

RESULTS

The preoperative model for end-stage liver disease (MELD) score [odds ratio (OR) = 2.7, 95%CI: 1.2-5.7, P = 0.013], tumor diameter (OR = 5.4, 95%CI: 2-14.8, P = 0.001) and duration of hospital stay (OR = 2.5, 95%CI: 1.5-4.2, P = 0.001) were significant independent predictors of hepatic decompensation after resection. While the preoperative MELD score [hazard ratio (HR) = 1.37, 95%CI: 1.16-1.62, P < 0.001] and different grades of PHLF (grade A: HR = 2.33, 95%CI: 0.59-9.24; Grade B: HR = 3.15, 95%CI: 1.11-8.95; Grade C: HR = 373.41, 95%CI: 66.23-2105.43; P < 0.001) and HCC recurrence (HR = 11.67, 95%CI: 4.19-32.52, P < 0.001) were significant independent predictors for survival.

CONCLUSION

Preoperative MELD score and tumor diameter can independently predict hepatic decompensation. While, preoperative MELD score, different grades of PHLF and HCC recurrence can precisely predict survival.

Identification of the Most Important Subset of Doppler, Laboratory, and Clinical Parameters for Serial TIPS Evaluation

OBJECTIVE. The purpose of the present study was to identify the subset of a wide range of serial Doppler, laboratory, and clinical parameters most predictive (both individually and in combination) of TIPS dysfunction in a large patient sample. MATERIALS AND METHODS. The medical records of 189 patients who had undergone TIPS procedures were analyzed. The patients (mean age, 52 years; 62% of whom were men) had undergone 1139 Doppler studies and 323 portovenograms. Laboratory parameters included model for end-stage liver disease (MELD) scores, serum albumin levels, presence of ascites, and time since last intervention. Doppler parameters included intrashunt velocities, temporal change in intrashunt velocities, main portal vein velocity, direction of flow in the left portal hepatic vein, and venous pulsatility index. Statistical analysis used ROC, univariate, and multivariate regression models to assess the parameters both individually and in combination. Shunt dysfunction was defined by a portosystemic gradient of more than 12 mm Hg. RESULTS. The laboratory and clinical parameters of greatest predictive value included the MELD score and the time since the last intervention. The Doppler parameters that were of greatest predictive value included the change in velocity at the hepatic venous end and the left portal vein flow direction. Multivariate models produced an AUC of 0.74. Differences between functional and dysfunctional shunts were also statistically significant for absolute velocity at the hepatic venous end, the change in velocity within the stent, and the temporal change in the mid shunt velocity. CONCLUSION. The subset of serial parameters most predictive of TIPS dysfunction are the temporal change in the velocity at the hepatic venous end, the absolute velocity at the hepatic venous end, the direction of flow in the left portal venous branch, and changes in the MELD score.

Systemic Inflammatory Response Syndrome in Patients Hospitalized for Acute Decompensation of Cirrhosis

BACKGROUND

Although recently challenged, systemic inflammatory response syndrome (SIRS) criteria are still commonly used in daily practice to define sepsis. However, several factors in liver cirrhosis may negatively impact its prognostic ability. Goals. To investigate the factors associated with the presence of SIRS, the characteristics of SIRS related to infection, and its prognostic value among patients hospitalized for acute decompensation of cirrhosis. Study. In this cohort study from two tertiary hospitals, 543 patients were followed up, up to 90 days. Data collection, including the prognostic models, was within 48 hours of admission.

RESULTS

SIRS was present in 42.7% of the sample and was independently associated with upper gastrointestinal bleeding (UGB), ACLF, infection, and negatively related to beta-blockers. SIRS was associated with mortality in univariate analysis, but not in multiple Cox regression analysis. The Kaplan-Meier survival probability of patients without SIRS was 73.0% and for those with SIRS was 64.7%. The presence of SIRS was not significantly associated with mortality when considering patients with or without infection, separately. Infection in SIRS patients was independently associated with Child-Pugh C and inversely related to UGB. Among subjects with SIRS, mortality was independently related to the presence of infection, ACLF, and Child-Pugh C.

CONCLUSIONS

SIRS was common in hospitalized patients with cirrhosis and was of no prognostic value, even in the presence of infection.

Prognostic Value of the CLIF-C AD Score in Patients With Implantation of Transjugular Intrahepatic Portosystemic Shunt

Prognostic assessment of patients with liver cirrhosis allocated for implantation of a transjugular intrahepatic portosystemic shunt (TIPS) is a challenging task in clinical practice. The aim of our study was to assess the prognostic value of the CLIF-C AD (Acute Decompensation) score in patients with TIPS implantation. Transplant-free survival (TFS) and 3-month mortality were reviewed in 880 patients who received de novo TIPS implantation for the treatment of cirrhotic portal hypertension. The prognostic value of the CLIF-C AD score was compared with the Model for End-Stage Liver Disease (MELD) score, Child-Pugh score, and albumin-bilirubin (ALBI) score using Harrell's C concordance index. The median TFS after TIPS implantation was 40.0 (34.6-45.4) months. The CLIF-C AD score (c = 0.635 [0.609-0.661]) was superior in the prediction of TFS in comparison to MELD score (c = 0.597 [0.570-0.623], P = 0.006), Child-Pugh score (c = 0.579 [0.552-0.606], P < 0.001), and ALBI score (c = 0.573 [0.545-0.600], P < 0.001). However, the CLIF-C AD score did not perform significantly better than the MELD-Na score (c = 0.626 [0.599-0.653], P = 0.442). There were no profound differences in the scores' ranking with respect to indication for TIPS implantation, stent type, or underlying liver disease. Subgroup analyses revealed that a CLIF-C AD score >45 was a predictor of 3-month mortality in the supposed low-risk group of patients with a MELD score ≤12 (14.7% vs. 5.1%, P < 0.001). Conclusion: The CLIF-C AD score is suitable for prognostic assessment of patients with cirrhotic portal hypertension receiving TIPS implantation. In the prediction of TFS, the CLIF-C AD score is superior to MELD score, Child-Pugh score, and ALBI score but not the MELD-Na score.

Development and Evaluation of a Physiologically Based Pharmacokinetic Drug-Disease Model of Propranolol for Suggesting Model Informed Dosing in Liver Cirrhosis Patients

AIM

The study was aimed to understand the underlying causes for the differences in propranolol pharmacokinetics (PK) between healthy and cirrhosis populations by using a systematic whole-body physiologically based pharmacokinetic (PBPK) model-building approach for suggesting model informed propranolol dosing in liver cirrhosis patients with different stages of disease severity.

METHODS

A whole-body PBPK model was developed by using population simulator PK-Sim® by using reported physicochemical and clinical data for propranolol in healthy and liver cirrhosis populations. The model evaluation was done by visual verification and comparison of PK parameters using their observed/predicted ratios (Robs/pred).

RESULTS

The developed model has effectively described the disposition of propranolol after intravenous and oral application in healthy and liver cirrhosis populations. All the model predictions were comparable to the observed clinical data and the Robs/pred for all the PK parameters were within a 2-fold range. A significant increase in plasma concentration of propranolol and decrease in drug clearance was observed in progressive stages of liver cirrhosis. The developed model after evaluation with the reported clinical PK data was used for suggesting model informed propranolol dosing in different stages of liver cirrhosis based on systemic unbound drug concentration.

CONCLUSION

The developed PBPK model has successfully described propranolol PK in healthy and cirrhosis populations after IV and oral administration. The evaluated PBPK propranolol-cirrhosis model can have many implications in predicting propranolol dosing in liver cirrhosis patients with different stages of disease severity.

Proprotein convertase subtilisin/kexin type 9 (PCSK9) levels are not associated with severity of liver disease and are inversely related to cholesterol in a cohort of thirty eight patients with liver cirrhosis

BACKGROUND

Proprotein convertase subtilisin/kexin type 9 (PCSK9) is of particular importance in cholesterol metabolism with high levels contributing to hypercholesterolemia. Cholesterol and sphingolipids are low in patients with liver cirrhosis. Purpose of this study was to find associations of plasma PCSK9 with circulating cholesterol and sphingolipid species and measures of liver disease severity in patients with liver cirrhosis.

METHODS

PCSK9 protein levels were determined by ELISA in systemic vein (SVP), hepatic vein (HVP) and portal vein plasma of patients with mostly alcoholic liver cirrhosis. PCSK9 and LDL-receptor protein expression were analysed in cirrhotic and non-cirrhotic liver tissues.

RESULTS

Serum PCSK9 was reduced in patients with liver cirrhosis in comparison to non-cirrhotic patients. In liver cirrhosis, plasma PCSK9 was not correlated with Child-Pugh score, Model for End-Stage Liver Disease score, bilirubin or aminotransferases. A negative association of SVP PCSK9 with albumin existed. PCSK9 protein in the liver did not change with fibrosis stage and was even positively correlated with LDL-receptor protein levels. Ascites volume and variceal size were not related to PCSK9 levels. Along the same line, transjugular intrahepatic shunt to lower portal pressure did not affect PCSK9 concentrations in the three blood compartments. Serum cholesterol, sphingomyelin and ceramide levels did not correlate with PCSK9. Stratifying patients by high versus low PCSK9 levels using the median as cut-off, several cholesteryl ester species were even low in the subgroup with high PCSK9 levels. A few sphingomyelin species were also reduced in the patients with PCSK9 levels above the median. PCSK9 is highly expressed in the liver but systemic, portal and hepatic vein levels were similar. PCSK9 was not correlated with the inflammatory proteins C-reactive protein, IL-6, galectin-3, resistin or pentraxin 3. Of note, HVP PCSK9 was positively associated with HVP chemerin and negatively with HVP adiponectin levels.

CONCLUSIONS

In the cohort of patients with liver cirrhosis mostly secondary to alcohol consumption high PCSK9 was associated with low levels of certain cholesteryl ester and sphingomyelin species. Positive correlations of PCSK9 and LDL-receptor protein in the liver of patients with chronic liver injury are consistent with these findings.

Paraphenylenediamine and related chemicals as allergens responsible for allergic contact dermatitis

INTRODUCTION

Paraphenylenediamine (PPDA) is a chemical with strong sensitizing properties used for dyeing of hair and textiles. Paraphenylenediamine can cross-react, resulting in allergy to other related compounds. The prevalence of PPDA sensitization varies widely. The objectives were to assess the frequency of positive patch test reactions to PPDA and related chemicals among patients with allergic contact dermatitis (ACD) and to analyze them regarding their clinical pattern, occupation and cross-reactions.

MATERIAL AND METHODS

The sociodemographic and clinical data of patients with positive patch tests to PPDA, N-isopropyl-N-phenyl-4-phenylenediamine (IPPD), ethylenediamine (EDA), triethylenetetramine (TETA) and toluene-2,5-diamine (TDA) were analyzed. The frequency, strength and cross-reactions with other chemicals were assessed.

RESULTS

Of 4087 ACD patients patch-tested between 2006 and 2015, positive reactions to PPDA and other amines were found in 166 (4.1%). The occupational character of PPDA allergy was established in 34.3% of patients. Personal history of atopy was reported by 36.7% of patients. In 98% of those examined, allergy presented as ACD, most frequently affecting hands. Hypersensitivity to PPDA was diagnosed in 77.1%, to IPPD in 20.5%, to TDA in 6%, to TETA in 1.2%, and to EDA in 0.6% of cases. The patients with an extremely strong PPDA reaction significantly more frequently showed reactions to other para group chemicals, especially to benzocaine.

CONCLUSIONS

Paraphenylenediamine was a major cause of contact allergy of diverse clinical picture more often affecting women, especially with atopy. Every fifth PPDA-allergic person exhibited hypersensitivity to other related compounds. Strong reactions to PPDA increased the risk of cross-reactions.

The role of interventional radiology in the pre-liver transplant patient

Each year approximately 8500 patients undergo liver transplantation in the USA for acute and chronic liver failure. Over the years, the success of liver transplantation has led to more clinical indications for liver transplantation. These expanded indications, without a proportionate increase in donors, result in increased competition for the limited pool of transplantable whole or partial grafts. The likelihood of receiving a deceased donor graft depends on many clinical variables, including the acute and chronic fitness of the candidate aligning with the timing of donor organ availability. Several types of patients are candidates for transplant: patients with acute fulminant hepatic failure who will die without a transplant, patients with decompensated cirrhosis, and patients with HCC and compensated cirrhosis. Interventional radiology can preserve equity between these subgroups and reduce patient dropout by increasing the physiologic and anatomic fitness of the candidate before and after formal listing. The primary determinants of candidacy fitness and dropout are the severity of clinical symptoms related to portal hypertension and the presence of hepatocellular cancer. There is a subgroup of patients whose disease severity is not accurately reflected by the Model for End-stage Liver Disease (MELD), such as patients with chronic cholestasis that also may benefit from IR management.

Pretransplant ascites and encephalopathy and their influence on survival and liver graft rejection in alcoholic cirrhosis disease

INTRODUCTION

The Child-Pugh and model for end-stage liver disease (MELD) scores are widely used to predict the outcomes of liver transplant (LT). Both have similar prognostic values in most cases, although their benefits might differ in some specific conditions. The aim of our study was to analyze the influence of pre-transplant ascites and encephalopathy in post-transplant liver rejection development and survival in alcohol cirrhosis (AC) patients undergoing LT to determine the usefulness of the Child-Pugh score for the assessment of prognosis in such patients.

MATERIAL AND METHODS

Two hundred and eighty-one AC patients, classified according to viral infections and pre-transplant complications, were analyzed. Acute (AR) and chronic (CR) liver rejections and Child-Pugh, MELD and albumin-bilirubin (ALBI) scores were studied in all cases.

RESULTS

Similar AC rejection percentages were observed in ascites or encephalopathy groups (18.5% and 16.5%, p = 0.735), although a higher but not statistically significant AC rate was observed in patients with grade III ascites (p = 0.777) and with grade II encephalopathy (p = 0.089). Chronic rejection was only developed by 9.1% of AC patients, regardless of the presence of ascites (6.2%) or encephalopathy (5.5%). The presence of ascites and encephalopathy complications did not seem to influence post-transplant survival. Neither the Child-Pugh nor the ALBI score can be considered the best for predicting patient survival in the short or long term.

CONCLUSIONS

Ascites and encephalopathy do not seem to influence AC or CR in patient survival, regardless of the presence of viral infections, so in our study neither the Child-Pugh nor ALBI score seems to be the best score to predict the outcomes of these patients.

Infection as a predictor of mortality in decompensated liver cirrhosis: exploring the relationship to severity of liver failure

BACKGROUND

Infections are common in patients with liver cirrhosis and increase mortality. We explored the relationship between infection and liver dysfunction in their effects on mortality.

METHODS

Single-center data on decompensated liver cirrhosis patients hospitalized between March 2014 and December 2017 (index period) were reviewed until death, liver transplantation or 31 December 2018. Infections were classified as community-acquired infection (CAi) or hospital/healthcare associated infection (HCAi). Child-Pugh, model for the end-stage liver disease (MELD) and chronic liver failure-organ failure (CLiF-OF) scores indicated liver (dys)function.

RESULTS

We enrolled 155 patients (85% alcoholic liver disease), 65 without infection at first hospitalization, 48 with CAi and 42 with HCAi. Multidrug resistant agents were confirmed in 2/48 (4.2%) CAi and 10/42 (23.8%) HCAi patients. At first hospitalization, infection was independently associated with worse liver dysfunction and vice versa, and with higher 30-day mortality [odds ratio (OR) = 2.73, 95% confidence interval (CI) 1.07-6.94]. The association was reduced with adjustment for MELD/CLiF-OF scores, but mediation analysis detected an indirect (via liver dysfunction) association. Twenty-eight patients were repeatedly hospitalized, 11 with new HCAi. HCAi was independently associated with twice higher risk of medium-term mortality and added an additional risk to any level of liver dysfunction, considering all or patients who survived the first 30 days. In those repeatedly hospitalized, HCAi appeared independently associated with a higher probability of infection and higher MELD scores at subsequent hospitalizations.

CONCLUSION

Infection (particularly HCAi) adds mortality risk to any level of liver dysfunction in decompensated liver cirrhosis patients. Mechanisms of long(er)-term effects (in acute episode survivors) seemingly include enhanced deterioration of liver function.

Transjugular intrahepatic portosystemic stent-shunt in the management of portal hypertension

These guidelines on transjugular intrahepatic portosystemic stent-shunt (TIPSS) in the management of portal hypertension have been commissioned by the Clinical Services and Standards Committee (CSSC) of the British Society of Gastroenterology (BSG) under the auspices of the Liver Section of the BSG. The guidelines are new and have been produced in collaboration with the British Society of Interventional Radiology (BSIR) and British Association of the Study of the Liver (BASL). The guidelines development group comprises elected members of the BSG Liver Section, representation from BASL, a nursing representative and two patient representatives. The quality of evidence and grading of recommendations was appraised using the GRADE system. These guidelines are aimed at healthcare professionals considering referring a patient for a TIPSS. They comprise the following subheadings: indications; patient selection; procedural details; complications; and research agenda. They are not designed to address: the management of the underlying liver disease; the role of TIPSS in children; or complex technical and procedural aspects of TIPSS.

Safety and feasibility of transjugular intrahepatic portosystemic shunt in elderly patients with liver cirrhosis and refractory ascites

BACKGROUND & AIMS

The management of patients with refractory ascites (RA) is challenging, particularly at higher age. Transjugular intrahepatic portosystemic shunt (TIPS) is an established treatment for RA, but safety data in elderly patients are rare. Our aim was to evaluate the safety and feasibility of TIPS in elderly patients with RA.

METHODS

Overall, 160 consecutive cirrhotic patients receiving a TIPS for RA at Hannover Medical School between 2012 and 2018 were considered for this retrospective analysis. Periinterventional complications such as acute-on-chronic liver failure (ACLF) as well as survival were compared between patients <65 and ≥65 years. Propensity score matching was conducted to match elderly TIPS patients and patients treated with paracentesis.

RESULTS

A number of 53 out of the 160 patients were ≥65 years (33%). Periinterventional course in those ≥65 years appeared to be slightly more complicated than in <65 years as reflected by a significantly longer hospital stay (p = 0.030) and more ACLF-episodes (21% vs. 9%; p = 0.044). 28-day mortality was similar between both groups (p = 0.350), whereas survival of the younger patients was significantly higher at 90 days (p = 0.029) and numerically higher at 1 year (p = 0.171). In the multivariate analysis age ≥65 years remained an independent predictor for 90-day mortality (HR: 2.58; p = 0.028), while it was not associated with 28-day and 1-year survival. Importantly, after matching for potential confounders 1-year survival was similar in elderly patients if treated with TIPS or paracentesis (p = 0.419).

CONCLUSIONS

TIPS placement in elderly patients with RA appears to be slightly more complicated compared to younger individuals, but overall feasible and at least not inferior to paracentesis.

Serial assessment of hepatic encephalopathy in patients hospitalised for acute decompensation of cirrhosis

INTRODUCTION AND AIM

Hepatic encephalopathy (HE) is a frequent complication of cirrhosis, but the clinical and prognostic significance of the progression of mental status in hospitalised cirrhotics is unknown. We aimed to investigate the prognostic significance of serial evaluation of HE in patients hospitalised for acute decompensation (AD) of cirrhosis.

MATERIALS AND METHODS

Patients (n=293) were evaluated for HE (West-Haven criteria) at admission and at day-3 and classified in two groups: (1) Absent or improved HE: HE absent at admission and at day-3, or any improvement at day-3; (2) Unfavourable progression: Development of HE or HE present at admission and stable/worse at day-3.

RESULTS

Unfavourable progression of HE was observed in 31% of patients and it was independently associated with previous HE, Child-Pugh C and acute-on-chronic liver failure (ACLF). MELD score and unfavourable progression of HE were independently associated with 90-day mortality. The 90-day Kaplan-Meier survival probability was 91% in patients with MELD<18 and absent or improved HE and only 31% in subjects with both MELD≥18 and unfavourable progression of HE. Unfavourable progression of HE was also related to lower survival in patients with or without ACLF. Worsening of GCS at day-3 was observed in 11% of the sample and was related with significantly high mortality (69% vs. 27%, P<0.001).

CONCLUSION

Among cirrhotics hospitalised for AD, unfavourable progression of HE was associated with high short-term mortality and therefore can be used for prognostication and to individualise clinical care.

Assessing the Prognostic Performance of the Child-Pugh, Model for End-Stage Liver Disease, and Albumin-Bilirubin Scores in Patients with Decompensated Cirrhosis: A Large Asian Cohort from Gastroenterology Department

Background and Aim. Various methods, including the Child-Pugh score, the model for end-stage liver disease (MELD) score, the MELD combined with serum sodium concentration (MELD-Na) score, the integrated MELD (iMELD) score, and the albumin-bilirubin (ALBI) score, have been widely used for predicting the survival of decompensated cirrhosis (DeCi) patients. In this study, we defined and compared the prognostic value of these scores to predict mortality in DeCi patients.

MicroRNA profiles in serum samples from Acute-On-Chronic Liver Failure patients and miR-25-3p as a potential biomarker for survival prediction

Acute-on-chronic liver failure (ACLF) is a condition characterized by acute decompensation of cirrhosis, associated with organ failure(s), and high short-term mortality. The microRNAs or miRNAs are small non-coding RNA molecules, stable in circulating samples such as biological fluids, and the difference in expression levels may indicate the presence, absence and/or stage of the disease. We analyzed here the miRNA profiling to identify potential diagnostic or prognostic biomarkers for ACLF. The major miRNAs discovered were validated in a cohort of patients with acute decompensation of cirrhosis grouped in no ACLF or ACLF according to EASL-CLIF definition. Relationship between serum miRNAs and variables associated with liver-damage and survival outcomes were verified to identify possible prognostic markers. Our results showed twenty altered miRNAs between no ACLF and ACLF patients, and twenty-seven in patients who died in 30 days compared with who survived. In validation phase, miR-223-3p and miR-25-3p were significantly altered in ACLF patients and in those who died in 30 days. miR-223-3p and miR-25-3p expression were associated with the lowest survival in 30 days. The decrease in miR-223-3p and miR-25-3p expression was associated with the presence of ACLF and poor prognosis. Of these, miR-25-3p was independently related to ACLF and 30-day mortality.

Role of Transjugular Intrahepatic Portosystemic Shunt in the Management of Portal Hypertension: Review and Update of the Literature

Transjugular intrahepatic portosystemic shunt (TIPS) is a well-established procedure used in the management of complications of portal hypertension. Although the most robust evidence supports the use of TIPS as salvage therapy in variceal hemorrhage, secondary prophylaxis of variceal bleeding, and treatment of refractory ascites, there is also data to suggest its efficacy in other indications such as hepatic hydrothorax, hepatorenal syndrome, and Budd-Chiari syndrome. Recent literature also suggests that TIPS may improve survival for certain subpopulations if placed early after variceal bleeding. This article provides an updated evidence-based review of the indications for TIPS. Outcomes, complications, and adequate patient selection are also discussed.

Allocation of liver grafts worldwide - Is there a best system?

BACKGROUND & AIMS

An optimal allocation system for scarce resources should simultaneously ensure maximal utility, but also equity. The most frequent principles for allocation policies in liver transplantation are therefore criteria that rely on pre-transplant survival (sickest first policy), post-transplant survival (utility), or on their combination (benefit). However, large differences exist between centers and countries for ethical and legislative reasons. The aim of this study was to report the current worldwide practice of liver graft allocation and discuss respective advantages and disadvantages.

METHODS

Countries around the world that perform 95 or more deceased donor liver transplantations per year were analyzed for donation and allocation policies, as well as recipient characteristics.

RESULTS

Most countries use the model for end-stage liver disease (MELD) score, or variations of it, for organ allocation, while some countries opt for center-based allocation systems based on their specific requirements, and some countries combine both a MELD and center-based approach. Both the MELD and center-specific allocation systems have inherent limitations. For example, most countries or allocation systems address the limitations of the MELD system by adding extra points to recipient's laboratory scores based on clinical information. It is also clear from this study that cancer, as an indication for liver transplantation, requires special attention.

CONCLUSION

The sickest first policy is the most reasonable basis for the allocation of liver grafts. While MELD is currently the standard for this model, many adjustments were implemented in most countries. A future globally applicable strategy should combine donor and recipient factors, predicting probability of death on the waiting list, post-transplant survival and morbidity, and perhaps costs.

LAY SUMMARY

An optimal allocation system for scarce resources should simultaneously ensure maximal utility, but also equity. While the model for end-stage liver disease is currently the standard for this model, many adjustments were implemented in most countries. A future globally applicable strategy should combine donor and recipient factors predicting probability of death on the waiting list, post-transplant survival and morbidity, and perhaps costs.

Evaluation of model performance to predict survival after transjugular intrahepatic portosystemic shunt placement

Background/Aims

The MELD score was developed to predict survival after transjugular intrahepatic portosystemic shunt (TIPS) placement. Given changes in practice patterns and development of new prognostic tools in cirrhosis, we aimed to evaluate common models to predict mortality after TIPS placement.

Methods

Analysis of consecutive patients who underwent TIPS placement for ascites or bleeding. Performance to predict 90-day mortality was assessed by C statistic for six models (MELD, MELD-Na, CLIF-C ACLF, Child-Pugh, Platelet-Albumin-Bilirubin, and Emory score). Added predictive value to MELD score was assessed for univariate predictors of 90-day mortality. Stratified analysis by TIPS indication, emergent placement status, and TIPS stent type was performed.

Results

413 patients were analyzed (248 with variceal bleeding, 165 with refractory ascites). 90-day mortality was 27% (113/413). Mean MELD score was 15 ± 7.9. MELD score best predicted mortality for all patients (c = 0.779), for variceal bleeding (c = 0.844), and for emergent TIPS (c = 0.817). CLIF-C ACLF score best predicted mortality for refractory ascites (c = 0.707). Addition of sodium to the MELD score did not improve predictive value across multiple strata. Addition of hemoglobin improved MELD score’s predictive value in variceal bleeding. Addition of age improved MELD score’s predictive value in refractory ascites.

Conclusions

MELD score best predicted 90-day mortality. Addition of sodium to the MELD score did not improve its performance, though mortality prediction was improved using Age-MELD for ascites and Hemoglobin-MELD for bleeding. An individualized risk stratification approach may be best when considering candidates for TIPS placement.

Prognostic Significance of The New Criteria for Acute Kidney Injury in Cirrhosis

BACKGROUND

New criteria for acute kidney injury (AKI) in cirrhosis have been proposed, but its prognostic significance is unclear. This study aims to evaluate the prognostic significance of the AKI criteria in cirrhotic patients hospitalized for acute decompensation.

MATERIAL AND METHODS

This is a prospective cohort study. AKI was defined as an increase in creatinine (Cr) levels ≥ 0.3 mg/dL in 48 h or ≥ 50% of the basal value in the last 7d. AKI was divided into stages 1 (elevation: &lt; 2x basal), 2 (2 or 3x), and 3 (&gt; 3x).

RESULTS

In this study, 227 patients aged 53.9 ± 11.5 years were included, of whom 37% had AKI (28% AKI1, 5% AKI2, and 4% AKI3). Thirty percent of the patients died or were transplanted within 90 days from causes related to the presence of ascites at hospital admission and higher values of Chronic Liver Failure-Sequential Organ Failure Assessment (CLIF-SOFA) scores, but not to the presence of AKI. In a regression analysis conducted to assess the effect of the final Cr level in patients with AKI, 90-day mortality was associated with ascites, higher CLIF-SOFA score, and AKI with final Cr level ≥ 1.5 mg/dL. The patients with AKI with Cr levels ≥ 1.5 mg/dL showed lower transplant-free survival rates than those without AKI, and those with AKI1 with final Cr level &lt; 1.5 mg/dL.

CONCLUSIONS

Early AKI was frequent and associated with 90-day mortality or transplantation only when the final Cr level was ≥ 1.5 mg/dL. Distinct approaches are needed for patients with AKI1 according to final Cr.

Detection of Minimal Hepatic Encephalopathy in Iranian Patients with Cirrhosis

BACKGROUND

Minimal hepatic encephalopathy (MHE) is the mildest type of hepatic encephalopathy in patients with cirrhosis. Patients with MHE have normal clinical and physical examination but they show some neurocognitive dysfunctions that affect their quality of life negatively. The aim of the current study is to diagnose MHE in patients with cirrhosis and its associated factors.

METHODS

This is a cross-sectional study on 120 known cases of cirrhosis referred to hospitals affiliated to Isfahan University of Medical Sciences during 2014-17. The patients’ cirrhosis severity was evaluated using laboratory tests and physical examinations based on MELD (Model for End-stage Liver Disease) and Child-Pugh criteria. The patients’ demographics were filled in a checklist. All included patients with cirrhosis were asked to respond to the questions of Psychometric Hepatic Encephalopathy Score (PHES) test.

RESULTS

Mean age of the patients was 51.2 ± 9.7 years. 62 (51.7%) patients were men and 58 (48.3%) patients were women. The mean score of the patients based on MELD criteria was 14.03 ± 6.09. 26.7% of the patients presented MHE. Mean age of the patients with MHE was statistically less than the patients without MHE (p value < 0.001). Mean score of MELD criteria among the patients with diagnosis of MHE was significantly higher than the other group (p value < 0.001). The patients’ Child class was statistically associated with MHE (p value < 0.001). Men were significantly more affected than women (p value = 0.03).

CONCLUSION

MHE was associated with MELD score and Child class of the patients with cirrhosis. The noticeable point was reversible association of age with MHE. Further studies are recommended.
