Predictors of morbidity and mortality after the first episode of upper gastrointestinal bleeding in liver cirrhosis

Esophageal Varices Presenting With Massive Hematemesis in a Chronic Alcoholic: A Case Report on a Rare Condition

Esophageal varices are life-threatening complications in which the enlargement of the esophageal veins causes bleeding and reduces blood flow to the esophagus. They are complications caused by portal hypertension, renal failure, hepatic dysfunction, and infection. The leading cause of esophageal varices is cirrhosis, as patients with this disease are more susceptible to forming esophageal varices. Bleeding episodes occur due to the rupture of the blood vessels. We present the case of a 45-year-old male patient in the hospital with a history of chronic alcohol use and clinical symptoms of hematemesis, a distended abdomen, and melena. The patient experienced mild symptoms of giddiness and dizziness after undergoing various radiological investigations, laboratory tests, ultrasonography (USG), and CT scans. USG diagnosed portal hypertension, gross ascites, pleural effusion, and hepatosplenomegaly. A CT scan diagnosed the patient with esophageal varices and testicular carcinoma. Laboratory tests diagnosed anemia. The treatment plan included oral and intravenous iron supplements, blood transfusions, vitamin B12, folate supplements, and nonselective beta-blockers to manage portal hypertension and reduce variceal bleeding risk. During acute bleeding episodes, vasoconstrictors and endoscopic band ligation were employed. Regular endoscopies and hepatic venous catheterization were conducted to monitor and manage the condition. Follow-up included regular assessments of hemoglobin levels, iron status, liver function tests, and periodic endoscopies. The patient's adherence to beta-blockers was closely monitored. Esophageal varices, often resulting from portal hypertension because of cirrhosis, require early diagnosis and a combination of pharmacological and endoscopic treatments to prevent complications. Advances in treatment have reduced mortality rates, but effective management of portal hypertension and liver dysfunction remains crucial.

A Review of Terlipressin in Hepatorenal Syndrome: Targeting Endothelial Dysfunction and Subsequent Cardiovascular Adverse Events

Hepatorenal syndrome (HRS) is a serious complication of decompensated liver cirrhosis that results in acute kidney injury (AKI). The mortality rate is high. Endothelial dysfunction secondary to liver cirrhosis is a key driver of the development of portal hypertension, which is eventually complicated by ascites and HRS. Ultimately, splanchnic vasodilation and excess gut lymph production result in ascites, low effective arterial blood volume, and maladaptive compensatory mechanisms that contribute to renal hypoperfusion and injury. While the only curative treatment is liver transplantation, vasoconstrictors and albumin have been the mainstay of treatment for candidates who are ineligible or waiting for transplantation. On September 14, 2022, terlipressin, a V1 vasopressin receptor agonist, was approved by the Food and Drug Administration for the treatment of HRS-AKI. In clinical trials, terlipressin plus albumin have been superior to albumin alone and equivocal to noradrenaline plus albumin in renal function improvement. Terlipressin, however, does not improve survival, is costly, and is associated with severe adverse events-including severe cardiac and vascular complications. The aim of this review is to provide an overview of terlipressin pharmacology, adverse events-with a focus on cardiovascular complications-and comparative randomized controlled trials that resulted in the Food and Drug Administration's approval of terlipressin. New literature since its approval and ongoing clinical trials will also be highlighted.

Clinical and Dosimetric Results of Proton or Photon Radiation Therapy for Large (>5 cm) Hepatocellular Carcinoma: A Retrospective Analysis

PURPOSE

Our purpose was to report the clinical and dosimetric attributes of patients with large unresectable hepatocellular carcinoma (HCC) undergoing proton or photon radiation therapy.

METHODS AND MATERIALS

We retrospectively analyzed the outcomes and dosimetric indices of 159 patients with >5 cm nonmetastatic HCC who underwent definitive radiation therapy using either protons (N = 105) or photons (N = 54) between 2014 and 2018. Additional photon plans were performed in the 105 proton-treated patients using the same dose prescription criteria for intragroup dosimetric comparison.

RESULTS

After a median follow-up of 47 months, patients with biologically effective dose (BED10) ≥ 75 Gy exhibited significantly better local control (LC; 2-year: 85.6% vs 20.5%; P < .001), progression-free survival (PFS; median, 7.4 vs 3.2 months; P < .001), and overall survival (OS; median, 18.1 vs 7.3 months; P < .001) compared with those with BED10 < 75 Gy. Notably, proton-treated patients had a significantly higher BED10 (96 vs 67 Gy; P < .001) and improved LC (2-year: 88.5% vs 33.8%; P < .001), PFS (median, 7.4 vs 3.3 months; P = .001), and OS (median, 18.9 vs 8.3 months; P < .001) than those undergoing photon radiation therapy. Furthermore, patients treated with protons had significantly lower V1 of the liver (P < .001), mean upper gastrointestinal tract dose (P < .001), and mean splenic dose (P < .001), with significantly decreased incidences of radiation-induced liver disease (P = .007), grade ≥3 upper gastrointestinal bleeding (P = .001), and grade ≥3 lymphopenia (P = .003). On multivariate analysis, proton radiation therapy consistently correlated with superior LC (P < .001), PFS (P < .001), and OS (P < .001). In intragroup dosimetric comparison, photon plans demonstrated significantly higher mean liver dose (P < .001) compared with actually delivered proton treatments, and 72 (69%) of them had mean liver dose exceeding 28 Gy, which necessitated target dose de-escalation.

CONCLUSIONS

In the context of large HCC radiation therapy, a higher target BED10 was associated with improved outcomes. Notably, proton therapy has demonstrated the capability to deliver ablative doses while also being accompanied by fewer instances of severe toxicity.

MELD, MELD 3.0, versus Child score to predict mortality after acute variceal hemorrhage: A multicenter US cohort

BACKGROUND

Acute variceal hemorrhage is a major decompensating event in patients with cirrhosis and is associated with high 6-week mortality risk. Many prognostic models based on clinical and laboratory parameters have been developed to risk stratify patients on index bleeding presentation, including those based on the Model for End-Stage Liver Disease (MELD) and Child-Turcotte-Pugh (CTP). However, consensus on model performance remains unclear.

METHODS

Using a large US multicenter cohort of hospitalized patients with cirrhosis who presented with acute variceal hemorrhage, this study evaluates, recalibrates, and compares liver severity index-based models, including the more recent MELD 3.0 model, to investigate their predictive performance on 6-week mortality. Models were also recalibrated and externally validated using additional external centers.

RESULTS

All recalibrated MELD-based and CTP-based models had excellent discrimination to identify patients at higher risk for 6-week mortality on initial presentation. The recalibrated CTP score model maintained the best calibration and performance within the validation cohort. Patients with low CTP scores (Class A, score 5-6) were strongly associated with < 5% mortality, while high CTP score (Class C, score > 9) were associated with > 20% mortality.

CONCLUSION

Use of liver severity index-based models accurately predict 6-week mortality risk for patients admitted to the hospital with acute variceal hemorrhage and supports the utilization of these models in future clinical trials as well as their use in clinical practice.

Early prediction of acute kidney injury in patients with gastrointestinal bleeding admitted to the intensive care unit based on extreme gradient boosting

Background

Acute kidney injury (AKI) is a common and important complication in patients with gastrointestinal bleeding who are admitted to the intensive care unit. The present study proposes an artificial intelligence solution for acute kidney injury prediction in patients with gastrointestinal bleeding admitted to the intensive care unit.

Methods

Data were collected from the eICU Collaborative Research Database (eICU-CRD) and Medical Information Mart for Intensive Care-IV (MIMIC-IV) database. The prediction model was developed using the extreme gradient boosting (XGBoost) model. The area under the receiver operating characteristic curve, accuracy, precision, area under the precision-recall curve (AUC-PR), and F1 score were used to evaluate the predictive performance of each model.

Results

Logistic regression, XGBoost, and XGBoost with severity scores were used to predict acute kidney injury risk using all features. The XGBoost-based acute kidney injury predictive models including XGBoost and XGBoost+severity scores model showed greater accuracy, recall, precision AUC, AUC-PR, and F1 score compared to logistic regression.

Conclusion

The XGBoost model obtained better risk prediction for acute kidney injury in patients with gastrointestinal bleeding admitted to the intensive care unit than the traditional logistic regression model, suggesting that machine learning (ML) techniques have the potential to improve the development and validation of predictive models in patients with gastrointestinal bleeding admitted to the intensive care unit.

CHIBA score: a novel model for predicting 3-month mortality in a cohort of Decompensated Liver Disease (DCLD)

Background

Decompensated liver disease (DCLD) has high mortality, and its prediction is important to prognosticate and prioritize patients for liver transplantation. MELD, MELD variants, and CTP were widely tested for mortality prediction with few drawbacks. The aim of the study is to propose a new prognostic model for DCLD which is better than the existing scores.

Materials and methods

Retrospective study with 321 DCLD patients were enrolled. Patient relatives were telephonically contacted regarding date of death, and mortality at 3 months was assessed. Logistic regression was done, coefficient of beta of independent variables were found out, and a new CHIBA score was proposed.

CHIBA score = creatinine × 0.6 + HE × 0.4+ INR × 0.8 + bilirubin × 0.125 + ascites × 1.2) where C stands for creatinine, H for hepatic encephalopathy, I for INR, B for bilirubin, and A for ascites.

Results

CHIBA score has AUROC of 0.793 (at a cutoff of > 5.5, it has a sensitivity of 66% and specificity of 76%) compared to MELD-Na of 0.735 (cutoff > 25, sensitivity 65%, and specificity 72%); MELD of 0.727 (cutoff > 17 sensitivity of 80.37% and specificity of 55.14%); I-MELD of 0.72; MESO index of 0.72; and UKELD of 0.686. For validation, 214 patients were selected, and AUROC of CHIBA score in the validation cohort was 0.77. At a cutoff of > 5.5, it has a sensitivity of 60% and specificity of 77%.

Conclusion

CHIBA score is superior to MELD and MELD variants in predicting 3-month mortality, and it is validated in an external cohort. It can be calculated at bedside as it is a simple score with no logarithmic variables in it.

MELD-Lactate Predicts Poor Outcome in Variceal Bleeding in Cirrhosis

BACKGROUND

Predictors of poor outcome associated with variceal bleeding remain suboptimal. In patients with cirrhosis, serum lactate combined with Model for End-Stage Liver Disease (MELD-LA) improved prediction across heterogeneous populations. However, prognostic properties have not yet been assessed in the context of variceal bleeding.

AIMS

We aimed to evaluate the predictive performance of MELD-LA compared to MELD, lactate, and nadir hemoglobin in cirrhosis patients with variceal bleeding.

METHODS

In this multicenter study, we identified 472 patients with variceal bleeding from a German primary cohort (University Hospitals Hamburg/Frankfurt/Cologne), and two independent external validation cohorts [Veterans Affairs (VA), Baylor University]. Discrimination for 30-day mortality was analyzed and scores were compared. MELD-LA was evaluated separately in validation cohorts to ensure consistency of findings.

RESULTS

In contrast to nadir hemoglobin, MELD and peak-lactate at time of bleeding were significantly higher in 30-day non-survivors in the primary cohort (p = 0.708; p < 0.001). MELD-LA had excellent discrimination for 30-day mortality (AUROC 0.82, 95% CI 0.76-0.88), better than MELD and peak-lactate (AUROC 0.78, 95% CI 0.71-0.84; AUROC 0.73, 95% CI 0.66-0.81). MELD-LA predicted 30-day mortality independently of age, sex, severity of liver disease and vasopressor support (HR 1.29 per 1-point-increase of MELD-LA; 95% CI 1.19-1.41; p < 0.001). Similarly, MELD-LA demonstrated excellent discrimination for 30-day mortality in the VA (AUROC = 0.86, 95% CI 0.79-0.93) and Baylor cohort (AUROC = 0.85, 95% CI 0.74-0.95).

CONCLUSIONS

MELD-LA significantly improves discrimination of short-term mortality associated with variceal bleeding, compared to MELD, peak-lactate and nadir hemoglobin. Thus, MELD-LA might represent a useful and objective marker for risk assessment and therapeutic intervention in patients with variceal bleeding.

Early lactate clearance for predicting outcomes in patients with gastrointestinal bleeding

BACKGROUND

Acute gastrointestinal bleeding (GI bleeding) can range from mild symptoms to life-threatening conditions that require emergency intervention. Therefore, it is important to first identify the high-risk and low-risk patients in the emergency department (ED).

AIMS

This study aimed to investigate the usefulness of a three-hourly interval for determining the lactate clearance, which is shorter than the time interval in previous studies, in order to predict the prognosis early in patients with GI bleeding.

METHODS

This retrospective study involved patients who visited for complaining of GI bleeding symptoms. Initial lactate levels were measured upon arrival at the ED and measured again 3 h later after performing initial resuscitation. And 3-h lactate clearance was calculated. Lactate and 3-h lactate clearance for predicting outcomes were evaluated by the area under the receiver operating characteristic (AUROC) curve.

RESULTS

A total of 104 patients were enrolled and 21 patients (20.2%) died in the hospital. Multivariate logistic regression showed that 3-h lactate clearance was a significant predictor of in-hospital mortality. The AUROC of 3-h lactate clearance for predicting in-hospital mortality was 0.756. The sensitivity and specificity were 66.67% and 75.90%. On combining lactate clearance, total bilirubin, and PTT, the AUROC was 0.899 for predicting in-hospital mortality.

CONCLUSIONS

This study validated that lactate clearance at three-hourly intervals is useful for early prediction of mortality and prognosis in patients with GI bleeding. It is important to perform not only an initial lactate measurement, but also a follow-up lactate measurement after initial resuscitation to check the lactate clearance.

Comparison of risk scoring systems for upper gastrointestinal bleeding in patients after renal transplantation: a retrospective observational study in Hunan, China

Background

Upper gastrointestinal bleeding (UGIB) is a common complication in renal transplant recipients. However, the risk stratification value of bleeding scoring systems in these patients is unclear, and data regarding risk factors are limited.

Methods

Clinical data of renal transplant recipients in The Third Xiangya hospital were collected. The predictive ability of Glasgow Blatchford score (GBS), pre-endoscopy Rockall score (pRS), and AIMS65 score were assessed by the area under the receiver operating characteristic curve (AUROC). Risk factors of UGIB were analyzed using binary logistic regression analysis.

Results

A total of 220 patients were enrolled, of which 55 with UGIB. Endoscopy improved the overall survival rate of patients. Glasgow Blatchford score (AUROC 0.868) performed best at predicting UGIB patients who need intervention or death, with a threshold of 10, sensitivity and specificity were 82.4% and 70%, respectively. In terms of predicting mortality, the GBS score was comparable with AIMS65 score (p = 0.30) and pRS score (p = 0.42). Viral hepatitis, intravenous hormone usage, low platelet count, and low albumin level were significant factors associated with UGIB.

Conclusions

The Glasgow Blatchford score (AUROC 0.868) was best at predicting the need for intervention or death. However, their ability to predict mortality was limited, with AUROC less than 0.8. Our study also identified four independent risk factors for renal transplant recipients with UGIB.

Practice guidance for the use of terlipressin for liver cirrhosis-related complications

BACKGROUND

Liver cirrhosis is a major global health burden worldwide due to its high risk of morbidity and mortality. Role of terlipressin for the management of liver cirrhosis-related complications has been recognized during recent years. This article aims to develop evidence-based clinical practice guidance on the use of terlipressin for liver cirrhosis-related complications.

METHODS

Hepatobiliary Study Group of the Chinese Society of Gastroenterology of the Chinese Medical Association and Hepatology Committee of the Chinese Research Hospital Association have invited gastroenterologists, hepatologists, infectious disease specialists, surgeons, and clinical pharmacists to formulate the clinical practice guidance based on comprehensive literature review and experts' clinical experiences.

RESULTS

Overall, 10 major guidance statements regarding efficacy and safety of terlipressin in liver cirrhosis were proposed. Terlipressin can be beneficial for the management of cirrhotic patients with acute variceal bleeding and hepatorenal syndrome (HRS). However, the evidence regarding the use of terlipressin in cirrhotic patients with ascites, post-paracentesis circulatory dysfunction, and bacterial infections and in those undergoing hepatic resection and liver transplantation remains insufficient. Terlipressin-related adverse events, mainly including gastrointestinal symptoms, electrolyte disturbance, and cardiovascular and respiratory adverse events, should be closely monitored.

CONCLUSION

The current clinical practice guidance supports the use of terlipressin for gastroesophageal variceal bleeding and HRS in liver cirrhosis. High-quality studies are needed to further clarify its potential effects in other liver cirrhosis-related complications.

Outcomes for upper gastrointestinal bleeding during the first wave of the COVID-19 pandemic in the Toronto area

BACKGROUND AND AIM

Changes to endoscopy service availability during the COVID-19 pandemic may have affected management of upper gastrointestinal bleeding (UGIB). The aim of this study was to describe the impact of the pandemic on UGIB outcomes in the Toronto area in Canada.

METHODS

We described all adults admitted to general medicine wards or intensive care units at six hospitals in Toronto and Mississauga, Canada, with UGIB during the first wave of the COVID-19 pandemic (March 1 to June 30, 2020) and compared them with a historical cohort (March 1 to June 30, 2018 and 2019). We compared clinical outcomes (in-hospital mortality, length of stay, 30-day readmission, intensive care utilization, receipt of endoscopy, persistent bleeding, receipt of second endoscopy, and need for angiographic or surgical intervention) using multivariable regression models, controlling for demographics, comorbidities, and severity of clinical presentation.

RESULTS

There were 82.5 and 215.5 admissions per month for UGIB during the COVID-19 and control periods, respectively. There were no baseline differences between groups for demographic characteristics, comorbidities, or severity of bleeding. Patients in the COVID-19 group did not have significantly different unadjusted (3.9% vs 4.2%, P = 0.983) or adjusted mortality (adjusted odds ratio [OR] = 0.64, 95% confidence interval [CI] = 0.25-1.48, P = 0.322). Patients in COVID-19 group were less likely to receive endoscopy for UGIB in the unadjusted (61.8% vs 71.0%, P = 0.003) and adjusted (adjusted OR = 0.64, 95% CI = 0.49-0.84, P < 0.01) models. There were no differences between groups for other secondary outcomes.

CONCLUSIONS

While patients admitted for UGIB during the first wave of the pandemic were less likely to receive endoscopy, this had no impact on mortality or any secondary outcomes.

Endotoxin Translocation and Gut Barrier Dysfunction Are Related to Variceal Bleeding in Patients With Liver Cirrhosis

Background

Bacterial infections are associated with the risk of variceal bleeding through complex pathophysiologic pathways.

Objectives

The primary objective of the present case-control study was to investigate the role of bacterial translocation and intestinal barrier dysfunction in the pathogenesis of variceal bleeding. A secondary objective was to determine independent predictors of key outcomes in variceal bleeding, including bleeding-related mortality.

Methods

Eighty-four (n = 84) consecutive patients participated in the study, 41 patients with acute variceal bleeding and 43 patients with stable cirrhosis, and were followed up for 6 weeks. Peripheral blood samples were collected at patient admission and before any therapeutic intervention.

Results

Child-Pugh (CP) score (OR: 1.868; p = 0.044), IgM anti-endotoxin antibody levels (OR: 0.954; p = 0.016) and TGF-β levels (OR: 0.377; p = 0.026) were found to be significant predictors of variceal bleeding. Regression analysis revealed that albumin (OR: 0.0311; p = 0.023), CRP (OR: 3.234; p = 0.034) and FABP2 levels (OR:1.000, p = 0.040), CP score (OR: 2.504; p = 0.016), CP creatinine score (OR: 2.366; p = 0.008), end-stage liver disease model (MELD), Na (OR: 1.283; p = 0.033), portal vein thrombosis (OR: 0.075; p = 0.008), hepatocellular carcinoma (OR: 0.060; p = 0.003) and encephalopathy (OR: 0.179; p = 0.045) were significantly associated with 6-week mortality.

Conclusions

Bacterial translocation and gut barrier impairment are directly related to the risk of variceal bleeding. Microbiota-modulating interventions and anti-endotoxin agents may be promising strategies to prevent variceal bleeding.

Endoscopic management and outcome of non-variceal bleeding in patients with liver cirrhosis: A systematic review

BACKGROUND

Acute non-variceal bleeding accounts for approximately 20% of all-cause bleeding episodes in patients with liver cirrhosis. It is associated with high morbidity and mortality therefore prompt diagnosis and endoscopic management are crucial.

AIM

To evaluate available data on the efficacy of endoscopic treatment modalities used to control acute non-variceal gastrointestinal bleeding (GIB) in cirrhotic patients as well as to assess treatment outcomes.

METHODS

Employing PRISMA methodology, the MEDLINE was searched through PubMed using appropriate MeSH terms. Data are reported in a summative manner and separately for each major non-variceal cause of bleeding.

RESULTS

Overall, 23 studies were identified with a total of 1288 cirrhotic patients of whom 958/1288 underwent endoscopic therapy for acute non-variceal GIB. Peptic ulcer bleeding was the most common cause of acute non-variceal bleeding, followed by portal hypertensive gastropathy, gastric antral vascular ectasia, Mallory-Weiss syndrome, Dieaulafoy lesions, portal hypertensive colopathy, and hemorrhoids. Failure to control bleeding from all-causes of non-variceal GIB accounted for less than 3.5% of cirrhotic patients. Rebleeding (range 2%-25%) and mortality (range 3%-40%) rates varied, presumably due to study heterogeneity. Rebleeding was usually managed endoscopically and salvage therapy using arterial embolisation or surgery was undertaken in very few cases. Mortality was usually associated with liver function deterioration and other organ failure or infections rather than uncontrolled bleeding. Endoscopic treatment-related complications were extremely rare. Lower acute non-variceal bleeding was examined in two studies (197/1288 patients) achieving initial hemostasis in all patients using argon plasma coagulation for portal hypertensive colopathy and endoscopic band ligation or sclerotherapy for bleeding hemorrhoids (rebleeding range 10%-13%). Data on the efficacy of endoscopic therapy of cirrhotic patients vs non-cirrhotic controls with acute GIB are very scarce.

CONCLUSION

Endotherapy seems to be efficient as a means to control non-variceal hemorrhage in cirrhosis, although published data are very limited, particularly those comparing cirrhotics with non-cirrhotics and those regarding acute bleeding from the lower gastrointestinal tract. Rebleeding and mortality rates appear to be relatively high, although firm conclusions may not be drawn due to study heterogeneity. Hopefully this review may stimulate further research on this subject and help clinicians administer optimal endoscopic therapy for cirrhotic patients.

Predictors of early rebleeding after endoscopic therapy of first variceal bleeding in liver cirrhosis

Background

Despite the great advancement in therapeutic modalities for esophageal varices, early variceal rebleeding still occurs at high rates leading to an exaggeration of the morbidity and mortality for cirrhotic patients, so meticulous follow-up with optimum prediction and proper preventive measures for early variceal rebleeding are mandatory for increasing survival of those patients. In this respect, we evaluated the clinical, laboratory, abdominal ultrasound, and endoscopic criteria of variceal cirrhotic patients as possible risk predictors of early variceal rebleeding after endoscopic control of first variceal bleeding. All included patients were followed up blindly for 12 weeks after endoscopic control of bleeding for ascertainment of first variceal rebleeding. The demographic, clinical, laboratory, abdominal ultrasound, and upper gastrointestinal endoscopic criteria were evaluated for all patients at first admission.

Results

By univariate regression analysis, the statistically significant predictors for early variceal rebleeding were serum albumin, serum bilirubin, prothrombin concentration, Child-Pugh score, platelet count, spleen diameter, ascites, portal vein diameter and velocity, variceal size, variceal location, and red color sign. By using multivariate regression analysis, the most independent significant predictors were Child-Pugh score (sig: 0.001 and OR: 1.661), platelets count (sig: 0.000 and OR: 0.956), portal vein velocity (sig: 0.000 and OR: 0.664), variceal grading (sig: 0.000 and OR: 3.964), and variceal red color sign (sig: 0.000 and OR: 4.964). We used the multivariate regression coefficients for the significant predictors to build up early variceal rebleeding risk (EVRR) score with a significant discriminatory performance (AUC: 0.965 and sig: 0.000).

Conclusion

Child-Pugh score, platelet count, portal vein velocity, variceal grading, and variceal red color sign are independent risk predictors for early variceal rebleeding after successful control of first variceal bleeding in cirrhotic patients. Our proposed EVRR score could be helpful for the prediction of early variceal rebleeding in cirrhotic patients after endoscopic control of acute variceal bleeding; however, it should be externally validated in large prospective studies.

Primary endoscopic variceal ligation reduced acute variceal bleeding events but not long-term mortality in pediatric-onset portal hypertension

BACKGROUND/PURPOSE

Esophageal variceal bleeding (EVB) is a medical emergency in patients with portal hypertension (PHT). However, studies on the long-term outcomes of prophylactic endoscopic variceal ligation (EVL) in pediatric-onset PHT are lacking.

METHODS

Between 1999 and 2020, patients who received EVL in the Electronic Report System of the Pediatric Endoscopy Unit were included in this retrospective study. EVL was classified as primary prophylaxis when it was performed for esophageal varices (EVs) without previous bleeding. If it was implemented in acute EVB, the subsequent EVL was classified as secondary prophylaxis.

RESULTS

Fifty-eight patients aged 10 months to 33 years with 31 males were included. Thirty-eight patients were classified as primary prophylaxis group, and twenty, secondary prophylaxis group. The primary prophylaxis group experienced fewer 5-year EVB events than the secondary prophylaxis group (cumulative risk: 14.4% versus 32.4%). Still, it didn't significantly affect overall survival and biliary atresia transplant-free survival. Long-term mortality was significantly associated with higher serum direct bilirubin levels (≥0.55 mg/dL) and lower albumin levels (≤2.54 mg/dL) at the first EVL. Aspartate aminotransferase-to-platelet ratio index (APRI) with a cut-off value of 1.24 helped to predict EV presence at the initial esophagogastroduodenoscopy (EGD) (AUROC = 0.762, sensitivity 75.0%, and specificity 66.7%).

CONCLUSION

Primary prophylactic EVL, despite reducing acute EVB, may not change overall survival and biliary atresia transplant-free survival. APRI > 1.24 may predict EV presence at the first EGD and help to schedule a surveillance EGD. Higher direct bilirubin and lower albumin levels at the first EVL may relate to long-term mortality.

Retrograde transvenous obliteration for the prevention of variceal rebleeding in patients with hepatocellular carcinoma: a multicentre retrospective study

AIM

To evaluate the effectiveness and safety of retrograde transvenous obliteration (RTO) for the prevention of variceal rebleeding variceal rebleeding in patients with hepatocellular carcinoma (HCC).

MATERIALS AND METHODS

This multicentre retrospective study enrolled 79 patients with HCC who underwent RTO for the prevention of variceal rebleeding. Successful occlusion of the gastrorenal shunt and obliteration of the gastric varices were achieved in 74 patients, with a technical success rate of 93.7%. Of the remaining 74 patients (mean age, 64.9±10.3 years; 56 men), 66 (90.4%) had gastroesophageal varices and seven (9.6%) had isolated gastric varices. Thirty-two patients (43.8%) underwent balloon-occluded RTO, 40 patients (54.8%) underwent plug-assisted RTO, and one patient (1.4%) underwent coil-assisted RTO. No patients had major procedural complications.

RESULTS

Rebleeding occurred in seven patients (9.6%) during the follow-up period. The 6-week and 1-year actuarial probabilities of patients remaining free of rebleeding were 90.8±3.6% and 88.6±4.1%, respectively. The median survival was 12.6 (95% confidence interval [CI] 8-17.3) months. The 6-week, 1-year, and 3-year actuarial probabilities of survival were 83.2±4.4%, 51.1±6.6%, and 32.7±7%, respectively. New or worsening ascites and oesophageal varices occurred in 12 (16.4%) and 13 patients (17.8%), respectively, during the follow-up period. Overt hepatic encephalopathy occurred in one patient (1.4%) during the follow-up period. The Child-Pugh score remained comparable to that at baseline at 1 and 3 months.

CONCLUSION

RTO was effective and safe in preventing variceal rebleeding in patients with HCC.

Long-term Outcomes with Carvedilol versus Propranolol in Patients with Index Variceal Bleed: 6-year Follow-up Study

AIMS AND BACKGROUND

There is limited information on comparison of clinical outcomes with carvedilol for secondary prophylaxis following acute variceal bleed (AVB) when compared with propranolol. We report long-term clinical and safety outcomes of a randomised controlled trial comparing carvedilol with propranolol with respect to reduction in hepatic venous pressure gradient (HVPG) in patients after AVB.

METHODS

We conducted a post-hoc analysis of patients recruited in an open-label randomized controlled trial comparing carvedilol and propranolol following AVB, and estimated long-term rates of rebleed, survival, additional decompensation events and safety outcomes. Rebleed and other decompensations were compared using competing risks analysis, taking death as competing event, and survival was compared using Kaplan-Meier analysis.

RESULTS

Forty-eight patients (25 taking carvedilol; 23 propranolol) were followed up for 6 years from randomization. More number of patients on carvedilol had HVPG response when compared with those taking propranolol (72%- carvedilol versus 47.8% propranolol, p = 0.047). Comparable 1-year and 3-year rates of rebleed (16.0% and 24.0% for carvedilol versus 8.9% and 36.7% for propranolol; p = 0.457) and survival (94.7% and 89.0% for carvedilol versus 100.0% and 79.8% for propranolol; p = 0.76) were obtained. New/worsening ascites was more common in those receiving propranolol (69.5% vs 40%; p = 0.04). Other clinical decompensations and complications of liver disease occurred at comparable rates between two groups. Drug-related adverse-events were similar in both groups.

CONCLUSION

Despite higher degree of HVPG response, long-term clinical, survival and safety outcomes in carvedilol are similar to those of propranolol in patients with decompensated cirrhosis after index variceal bleed with the exception of ascites that developed less frequently in patients with carvedilol.

Comparison of various risk scores for the prognosis of hemorrhagic upper gastrointestinal mucosal disorder

Background

Various risk scores have been proposed that are useful for the management of upper gastrointestinal bleeding (UGIB), which is an important disease in emergency medicine. Few studies have examined the usefulness of Charlson Comorbidity index (CCI) in this disease, which evaluates the patient’s general condition by scoring the patient’s underlying disease. There have been no studies investigating the efficacy of CCI compared to other risk scores in the management of UGIB requiring endoscopic hemostasis.

Methods

In addition to the Glasgow-Blatchford score, AIMS65 score, and Rockall score, we investigated the efficacy of the outcome prediction obtained by the original CCI and the updated CCI, scored only with respect to the underlying disease. We also examined the cutoff value when using the risk score. This retrospective study included 265 patients with hemorrhagic upper gastrointestinal mucosal lesions who underwent emergency endoscopic hemostasis during a 6-year period between 2011 and 2016 in our hospital.

Results

The updated CCI and AIMS65 score correlated with prognosis in multivariate analysis (p = 0.002 and p = 0.003, respectively). In clinical practice, the prognosis might be worse if both updated CCI and AIMS65 score were 3 point or more.

Conclusion

In addition to the AIMS65 score, the updated CCI can be a useful tool for managing upper gastrointestinal mucosal disorder bleeding that requires endoscopic hemostasis.

Early rebleeding increases mortality of variecal bleeders on secondary prophylaxis with β-blockers and ligation

BACKGROUND/AIMS

Despite secondary-prophylaxis with β-blockers and endoscopic-variceal-ligation rebleeding is frequent, particularly within the first-6-weeks. Early-rebleeding may have greater impact on death-risk than late rebleeding, which may affect therapy. We assessed whether the influence of rebleeding on long-term survival of patients on secondary-prophylaxis is greater in patients with early-rebleeding.

METHODS

369 patients with cirrhosis were consecutively included once recovered from first variceal-bleeding. The impact of rebleeding on survival was investigated according to whether it occurred within 6-weeks (early-rebleeding) or later (late-rebleeding).

RESULTS

During 46-months of follow-up (IQR: 14-61), 45 patients (12%) had early-rebleeding, 74(20%) had late-rebleeding and 250(68%) had not rebleeding. Mortality risk was higher in early-rebleeding group vs. late-rebleeding (HR = 0.476, 95%CI = 0.318-0.712, p < 0.001) and was similar in late-rebleeding group vs. no-rebleeding (HR = 0.902, 95%CI = 0.749-1.086, p = 0.271). Adjusting for baseline risk-factors, early-rebleeding was independently associated with mortality-risk (HR = 1.58, 95%CI = 1.02-2.45; p = 0.04). Child-Pugh&MELD scores improved at 3rd-4th-week only in patients without early-rebleeding (p < 0.05). Presence of ascites or encephalopathy, MELD-score>12 and HVPG>20 mmHg identified patients at risk of early-rebleeding.

CONCLUSIONS

Patients with early-rebleeding have higher risk of death than patients without rebleeding and even than those rebleeding later. Our results suggest that patients at risk of early rebleeding might benefit from preemptive therapies such as early-TIPS.

Development of myocardial infarction and ischemic stroke after acute upper gastrointestinal bleeding

Cardiovascular disease, mainly including coronary artery disease and stroke, is the leading cause of mortality and morbidity worldwide. The traditional risk factors of cardiovascular disease include smoking, alcohol abuse, hypertension, diabetes mellitus, hyperlipidemia, and psychosocial stress. Herein, we reported one patient who developed myocardial infarction and ischemic stroke after acute upper gastrointestinal bleeding and discussed the potential association between cardiovascular disease and acuter upper gastrointestinal bleeding.

Incidence and mortality of renal dysfunction in cirrhotic patients with acute gastrointestinal bleeding: a systematic review and meta-analysis

Background: Gastrointestinal bleeding (GIB) is a common complication in cirrhosis. Renal dysfunction may be crucial for the outcomes of cirrhotic patients with acute GIB. This study aimed to explore the incidence and mortality of renal dysfunction in cirrhotic patients with acute GIB.Methods: The PubMed, EMBASE, and Cochrane Library databases were searched. We pooled the incidence and mortality of renal dysfunction in cirrhotic patients using a random-effect model. Odds ratio (OR) with 95% confidence interval (CI) were calculated.Results: Seventeen studies were included. The pooled incidence of renal dysfunction was 21% (95%CI = 16%-25%) in cirrhosis with acute GIB. In subgroup analyses, the pooled incidence of renal failure, acute kidney injury (AKI), and renal impairment were 21%, 25%, and 15%, respectively. The pooled mortality was 46% (95%CI = 37%-55%) in cirrhosis with acute GIB and renal dysfunction. In subgroup analyses, the pooled mortality in patients with renal failure, AKI, and renal impairment were 42%, 47%, and 49%, respectively. Renal dysfunction significantly increased the mortality of cirrhosis with acute GIB (OR = 4.92; 95%CI = 3.47-6.96; P < 0.001).Conclusion: Renal dysfunction is a common indicator for poor outcome of cirrhosis with acute GIB. Prevention of renal dysfunction in such patients should be further explored.

Clinical Outcome and Predictive Factors of Variceal Bleeding in Patients with Hepatocellular Carcinoma in Thailand

Objective:

Hepatocellular carcinoma (HCC) is common cancer in ASEAN. Variceal bleeding (VB) is considered to be fatal complication of cirrhosis with HCC. However, limited studies were reported in ASEAN. Aim of this study was to evaluate overall survival rate and predictors of VB in HCC patients.

Methods:

We conducted a retrospective cohort study of HCC patients aged ≥15 years between January 2012-January 2016 and follow up through June 2016 at Thammasat University Hospital, Thailand. Clinical information and radiologic findings were collected from reviewing computer database of medical records.

Results:

333 patients had completely retrievable information. Of which, 27 patients (8.1%) had documented with VB. Clinical presentations with weight loss and jaundice were higher in VB than non-VB groups (40.74% vs. 34.64%, p=0.525 and 7.41% vs. 2.29%, p=0.116) but the differences were not significant. The most common causes of cirrhosis in HCC patients with VB were chronic HBV infection (55.56%). In multivariate analysis; presence of ascites, Child-Pugh score>6, presence of varices were independent risk factors of having VB in HCC patients (OR=7.59, 95%CI=1.13-50.88, p=0.037; OR=5.07, 95%CI=1.08-23.76, p=0.039; OR=23.51, 95%CI=4.71-117.35, p<0.001, respectively). In HCC patients with VB, 1-year and 2.5-year survival rates were 56.6% and 28.3%.

Conclusions:

HCC patients with ascites, Child-Pugh score>6 and presence of varices might be important predictive factors of VB. Having VB were greatly impact to the survival rate of HCC patients. Clinical suspicion and regular surveillance of VB in HCC patients at risk could improve treatment outcomes.

Comparison of clinical outcomes between variceal and non-variceal gastrointestinal bleeding in patients with cirrhosis

BACKGROUND AND AIM

Acute upper gastrointestinal bleeding (UGIB) in cirrhosis is associated with significant morbidity and mortality and can be classified as acute variceal bleeding (AVB) or non-variceal bleeding (NVB). Differences in mortality, hospital length of stay (LOS), and 30-day readmission have yet to be determined. As such, the study aimed to evaluate differences in these clinical outcomes in cirrhotic patients admitted with UGIB.

METHODS

This retrospective study included all cirrhotic patients hospitalized for UGIB who underwent upper endoscopy from July 2014 to July 2016. AVB was defined as the presence of varices on endoscopy with high-risk stigmata such as cherry-red spots. Mortality, intensive care unit admission, hospital LOS, and 30-day hospital readmission were recorded and compared among patients with AVB and NVB.

RESULTS

A total of 116 patients with cirrhosis were included, 73 with AVB and 43 with NVB. Patients with NVB were older than those with AVB (60.4 ± 11.1 vs 55.0 ± 9.5, P = 0.006) whereas patients with AVB were more likely to have known esophageal varices (64.4% vs 37.2%, P = 0.007). Patients with AVB and NVB had similar mortality (15.1% vs 9.3%, P = 0.57), hospital LOS (4.9, interquartile range: 3.6-6.9 days vs 5.0, interquartile range: 2.7-8.3 days), and 30-day readmission rates (19.2% vs 30.2%, P = 0.18). Severity of clinical presentation was associated with increased LOS and overall mortality, including the need for intensive care unit admission, but these were not associated with 30-day readmission rates.

CONCLUSION

There were no differences in clinical outcomes, including mortality, in cirrhotic patients admitted with AVB and NVB.

Acute Variceal Bleeding Causes Significant Morbidity

BACKGROUND AND AIMS

The need for primary prophylaxis of variceal bleeding in children is unclear due to insufficient evidence of the efficacy of prophylactic therapy and the mortality and morbidity associated with the first bleeding event. Previous studies have provided estimates of mortality. We aimed to investigate the morbidity associated with acute variceal bleeding (AVB) in children and to identify contributing factors.

METHODS

We retrospectively reviewed children with chronic liver disease or portal vein thrombosis admitted with acute upper gastrointestinal bleeding between 2000 and 2015.

RESULTS

Seventy AVB episodes in 57 children (median age 6 years, 52% girls) were included, 58% with cirrhosis and 30% portal vein thrombosis. Approximately 67% were the patient's first bleed. Post-AVB morbidity was present in 57% of all episodes and in 64% of first bleeds and included: ascites (34%), infection (30%), respiratory complications (24%), intensive care unit admission (20%), rebleed (11%), encephalopathy (7%), acute kidney injury (6%), and failure to control bleed (4%). Two patients died (4% of first bleeds, 8% of cirrhotics' first bleeds) within 6 weeks of bleeding. Median length of stay was 7 days. Overall morbidity was associated with total bilirubin (P = 0.001). Ascites after AVB was associated with pediatric end-stage liver disease (P = 0.0007), total bilirubin (P = 0.001), and cirrhosis (P = 0.006). Median length of stay was longer in patients with morbidities (18 vs 4 days, P < 0.0001).

CONCLUSION

Children with AVB suffer significant morbidity but have a low risk of death. Morbidity should therefore be considered in future studies measuring the risks and benefits of primary prophylaxis of first AVB in children.

Tolvaptan in Chinese cirrhotic patients with ascites: A randomized, placebo-controlled phase 2 trial

OBJECTIVE

To evaluate tolvaptan as a novel therapeutic option for Chinese patients with liver cirrhosis-associated ascites in a phase 2 clinical trial.

METHODS

This randomized, double-blind, placebo-controlled, multicenter trial was conducted in patients with insufficient responses to combination therapies of an oral loop diuretic and an aldosterone antagonist. Reduction in body weight and abdominal circumference, increase in 24-h cumulative urine volume and improvement in serum sodium level from baseline to the end of treatment in the tolvaptan groups (15 mg/day or 30 mg/day orally) were compared with those in the placebo group. Drug safety was also assessed.

RESULTS

Sixty-two patients were allocated to the placebo group, 56 to the tolvaptan 15-mg group and 63 to the tolvaptan 30-mg group. Their mean changes in body weight were -0.5 ± 1.6 kg, -2.1 ± 2.0 kg and -1.9 ± 2.0 kg, respectively. Body weight reductions in both tolvaptan groups were significantly greater than that in the placebo group (difference -1.6, 95% confidence interval [CI] -2.5 to -0.8, and difference -1.4, 95% CI, -2.2 to -0.7, both P < 0.0001). The administration of tolvaptan also significantly reduced the abdominal circumference, increased 24-h cumulative urine volume and serum sodium level compared with placebo. The most common adverse events in the tolvaptan groups were constipation, diarrhea, dry mouth and thirst, with no severe adverse events observed.

CONCLUSION

Tolvaptan at 15 mg/day significantly reduced the body weight and abdominal circumference in patients with liver cirrhosis-associated ascites, which needs to be confirmed in a phase 3 trial.

Risk factors for hematemesis in Hoima and Buliisa Districts, Western Uganda, September-October 2015

Introduction

On 17 September 2015, Buliisa District Health Office reported multiple deaths due to haemorrhage to the Uganda Ministry of Health. We conducted an investigation to verify the existence of an outbreak and to identify the disease nature, mode of transmission and risk factors.

Methods

We defined a suspected case as onset of hematemesis between 1 June 2015 and 15 October 2015 in a resident of Hoima, Buliisa or neighbouring districts. We identified cases by reviewing medical records and actively searching in the community. We interviewed case-patients and health-care workers and performed descriptive epidemiology to generate hypotheses on possible exposures. In a case-control study we compared exposures between 21 cases and 81 controls, matched by age (± 10 years), sex and village of residence. We collected 22 biological specimens from 19 case-patients to test for Viral Haemorrhagic Fevers (VHF). We analysed the data using the Mantel-Haenszel method to account for the matched study design.

Results

We identified 56 cases with onset from June to October (attack rate 15/100,000 in Buliisa District and 5.2/100,000 in Hoima District). The age-specific attack rate was highest in persons aged 31-60 years (15/100,000 in Hoima and 47/100,000 in Buliisa); no persons below 15 years of age had the illness. In the case-control study, 42% (5/12) of cases vs. 0.0% (0/77) of controls had liver disease (OR_M-H = ∞; 95%CI = 3.7-∞); 71% (10/14) of cases vs. 35% (28/81) of controls had ulcer disease (OR_M-H = 13; 95% CI = 1.6-98); 27% (3/11) of cases vs. 14% (11/81) of controls used indomethacin prior to disease onset (OR_M-H = 6.0; 95% CI = 1.0-36). None of the blood samples were positive for any of the VHFs.

Conclusion

This reported cluster of hematemesis illness was due to predisposing conditions and use of Non-Steroidal Anti-inflammatory Drugs (NSAID). Health education should be conducted on the danger of NSAIDs misuse, especially in persons with pre-disposing conditions.

Outcomes in variceal hemorrhage following the use of a balloon tamponade device

BACKGROUND

Variceal hemorrhage is associated with high morbidity and mortality. A balloon tamponade device (BTD), such as the Sengstaken-Blakemore or Minnesota tube, may be used in cases of variceal hemorrhage. While these devices may be effective at controlling acute bleeding, the effect on patient outcomes remains less clear. We sought to describe the number of patients with variceal hemorrhage and a BTD who survive to discharge, survive to one-year, and develop complications related to a BTD.

METHODS

In this retrospective study, we identified patients at a single, tertiary care center who underwent placement of a BTD for upper gastrointestinal hemorrhage between 2003 and 2014. Patient characteristics and outcomes were summarized using descriptive statistics.

RESULTS

34 patients with a BTD were identified. Median age was 57.5 (IQR 47-63) and 76% (26/34) were male. Approximately 59% (20/34) of patients survived to discharge, and 41% (13/32) were alive after one year. Two patients were lost to follow-up. Of those surviving to discharge, 95% (19/20) had undergone transjugular intrahepatic portosystemic shunt (TIPS), while 36% (5/14) of patients who did not survive to discharge had TIPS (p<0.01). One complication, an esophageal perforation, was identified and managed conservatively.

CONCLUSION

In this cohort of patients undergoing BTD placement for variceal hemorrhage, approximately 59% of patients were alive at discharge and 41% were alive after one year. Placement of a BTD as a temporizing measure in the management of acute variceal hemorrhage may be helpful, particularly when utilized as a bridge to more definitive therapy.

Evaluating the current surgical strategies for hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related death worldwide. Despite careful surveillance programs and the development of antiviral therapy for hepatitis virus infection, the occurrence rate of HCC remains high. Liver resection and liver transplantation are mainstay curative treatments. Most patients with HCC have impaired liver function, and surgical treatment is always accompanied by the risk of decompensation of the remnant liver, especially when the volume of the remnant liver is too small and the liver function too low to meet metabolic demands. The mortality of liver resection has dramatically decreased over the last three decades from 20% to less than 5% due to the accumulation of knowledge of liver anatomy, perioperative management and preoperative assessment of liver function. Here we provide an overview of the multidisciplinary treatments and current standard treatment strategies for HCC, to explore the possibility of expanding surgical treatments beyond the current standards.

L‐ornithine L‐aspartate for people with cirrhosis and hepatic encephalopathy

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:

To assess the beneficial and harmful effects of L‐ornithine L‐aspartate versus placebo, no intervention, or other active interventions for people with cirrhosis and hepatic encephalopathy.

Serum Ammonia is Associated With Transplant-free Survival in Hospitalized Patients With Acutely Decompensated Cirrhosis [corrected]

BACKGROUND

As ammonia metabolism is a complex multiorgan process, we sought to determine whether serum ammonia concentrations were associated with transplant-free survival in patients with acutely decompensated cirrhosis and acute-on-chronic liver failure (ACLF).

METHODS

We studied 494 consecutive patients hospitalized with cirrhosis between April 2007 and September 2012 with venous ammonia measured on hospital admission. The primary outcome was transplant-free survival.

RESULTS

Overall, rates of death or transplant within 30 and 90 days were 23.1% (n=114) and 37.7% (n=186), respectively. Forty-six patients (9.2%) underwent liver transplantation within 90 days. In a multivariate Cox proportional hazards model, ammonia concentration was independently associated with death or transplantation within 30 and 90 days after adjusting for model for end-stage liver disease, sodium, white blood cells, and number of ACLF organ failures; every doubling of ammonia was associated with respective hazard ratios of 1.22 (95% confidence interval, 1.03-1.38) and 1.21 (95% confidence interval, 1.04-1.44) for 90- and 30-day transplant or mortality. Notably, after adjusting for ammonia, organ failures were not predictive of outcomes. In a Kaplan-Meier analysis, patients with admission ammonia concentrations >60 μmol/L had significantly lower 90-day transplant-free survival (P=0.0004). Patients with admission ammonia concentrations >60 μmol/L had higher 90- and 30-day risk of death or transplantation (45.2% vs. 31.2%, P=0.001; and 31.6% vs. 15.7%, P<0.0001, respectively).

CONCLUSION

For patients with acutely decompensated cirrhosis, an elevated serum ammonia concentration on admission is associated with reduced 90-day transplant-free survival after adjusting for established predictors.

The Role of IL-1 Family Members and Kupffer Cells in Liver Regeneration

Interleukin-1 (IL-1) family and Kupffer cells are linked with liver regeneration, but their precise roles remain unclear. IL-1 family members are pleiotropic factors with a range of biological roles in liver diseases, inducing hepatitis, cirrhosis, and hepatocellular carcinoma, as well as liver regeneration. Kupffer cells are the main source of IL-1 and IL-1 receptor antagonist (IL-1Ra), the key members of IL-1 family. This systemic review highlights a close association of IL-1 family members and Kupffer cells with liver regeneration, although their specific roles are inconclusive. Moreover, IL-1 members are proposed to induce effects on liver regeneration through Kupffer cells.

Effect of coexisting diabetes mellitus and chronic kidney disease on mortality of cirrhotic patients with esophageal variceal bleeding

BACKGROUND

Esophageal variceal bleeding (EVB) is a serious and common complication of cirrhosis. Diabetes mellitus (DM) and chronic kidney disease (CKD) increase mortality in patients with cirrhosis. However, whether coexisting DM and CKD increase mortality in cirrhotic patients with EVB remains unclear.

METHODS

We enrolled cirrhotic patients hospitalized with the first presentation of EVB from 2005 through 2010 using Longitudinal Health Insurance Database 2005. The hazard ratios (HRs) of 42-day and one-year EVB mortality were calculated using Cox regression model.

RESULTS

We identified 888 patients hospitalized with the first presentation of EVB. Among the cirrhotic patients with EVB, all-cause mortality at 42-day and one-year were 21.3 and 45.0 %, respectively. The respective HRs for the 42-day and one-year mortality were 1.80 (95 % confidence interval [CI], 1.10-2.97) and 1.52 (95 % CI, 1.06-2.17) for patients with CKD and 0.79 (95 % CI, 0.57-1.10) and 0.88 (95 % CI, 0.71-1.09) for patients with DM. Specifically, coexisting CKD and DM increased the 42-day and one-year mortality with respective HRs of 1.99 (95%CI, 1.03-3.84) and 1.84 (95%CI, 1.14-2.98) compared with those without CKD and DM. The HRs for 42-day and 1-year mortality in female patients with DM and CKD were 4.03 (95%CI, 1.40-11.59) and 2.84 (95%CI, 1.31-6.14) respectively, and were 2.93 (95%CI, 1.14-7.57) and 2.42 (95%CI, 1.28-4.57) in male patients with DM and CKD.

CONCLUSION

We identified that coexisting DM and CKD increased risk of mortality at 42 days and 1 year following EVB.

Distinctive aspects of peptic ulcer disease, Dieulafoy's lesion, and Mallory-Weiss syndrome in patients with advanced alcoholic liver disease or cirrhosis

AIM: To systematically review the data on distinctive aspects of peptic ulcer disease (PUD), Dieulafoy’s lesion (DL), and Mallory-Weiss syndrome (MWS) in patients with advanced alcoholic liver disease (aALD), including alcoholic hepatitis or alcoholic cirrhosis.

METHODS: Computerized literature search performed via PubMed using the following medical subject heading terms and keywords: “alcoholic liver disease”, “alcoholic hepatitis”,“ alcoholic cirrhosis”, “cirrhosis”, “liver disease”, “upper gastrointestinal bleeding”, “non-variceal upper gastrointestinal bleeding”, “PUD”, ‘‘DL’’, ‘‘Mallory-Weiss tear”, and “MWS’’.

RESULTS: While the majority of acute gastrointestinal (GI) bleeding with aALD is related to portal hypertension, about 30%-40% of acute GI bleeding in patients with aALD is unrelated to portal hypertension. Such bleeding constitutes an important complication of aALD because of its frequency, severity, and associated mortality. Patients with cirrhosis have a markedly increased risk of PUD, which further increases with the progression of cirrhosis. Patients with cirrhosis or aALD and peptic ulcer bleeding (PUB) have worse clinical outcomes than other patients with PUB, including uncontrolled bleeding, rebleeding, and mortality. Alcohol consumption, nonsteroidal anti-inflammatory drug use, and portal hypertension may have a pathogenic role in the development of PUD in patients with aALD. Limited data suggest that Helicobacter pylori does not play a significant role in the pathogenesis of PUD in most cirrhotic patients. The frequency of bleeding from DL appears to be increased in patients with aALD. DL may be associated with an especially high mortality in these patients. MWS is strongly associated with heavy alcohol consumption from binge drinking or chronic alcoholism, and is associated with aALD. Patients with aALD have more severe MWS bleeding and are more likely to rebleed when compared to non-cirrhotics. Pre-endoscopic management of acute GI bleeding in patients with aALD unrelated to portal hypertension is similar to the management of aALD patients with GI bleeding from portal hypertension, because clinical distinction before endoscopy is difficult. Most patients require intensive care unit admission and attention to avoid over-transfusion, to correct electrolyte abnormalities and coagulopathies, and to administer antibiotic prophylaxis. Alcoholics should receive thiamine and be closely monitored for symptoms of alcohol withdrawal. Prompt endoscopy, after initial resuscitation, is essential to diagnose and appropriately treat these patients. Generally, the same endoscopic hemostatic techniques are used in patients bleeding from PUD, DL, or MWS in patients with aALD as in the general population.

CONCLUSION: Nonvariceal upper GI bleeding in patients with aALD has clinically important differences from that in the general population without aALD, including: more frequent and more severe bleeding from PUD, DL, or MWS.

Benefit of cystatin C in evaluation of renal function and prediction of survival in patients with cirrhosis

AIM

The assessment of renal function is of vital importance in management of patients with cirrhosis. While serum creatinine (Cr) is routinely used for this purpose, Cr-based estimated glomerular filtration rate (eGFR) does not reflect true renal function because of muscle wasting and impaired liver function. By contrast, cystatin C (CysC) is unrelated to muscle volume and liver function. In this study, we examined whether CysC-based GFR estimation is beneficial in assessment of renal function in patients with cirrhosis.

METHODS

First, we assessed the performance of GFR-predicting equations based on serum Cr or CysC in 14 patients with cirrhosis, by comparison with inulin clearance as a gold standard of GFR (measured GFR [mGFR]). Next, in 49 patients with cirrhosis, we examined serum Cr and CysC at baseline, and examined which GFR-predicting equations were more suitable for predicting the outcome.

RESULTS

In the first experiment, mGFR was 54.3 ± 23.0 mL/min, and CysC-based GFR-estimating equations had better performances compared with Cr-based equations in terms of bias, precision and accuracy. Cr-based estimated GFR (eGFRcreat) was significantly different from mGFR (P < 0.05). In the follow-up study of 49 patients (observational period, 30.7 ± 32.0 months), multivariate analysis demonstrated that CysC-based estimated GFR (eGFRcys), along with albumin, Child-Pugh grade and presence of hepatocellular carcinoma, was independently associated with overall survival (odds ratio, 4.19; 95% confidence interval, 1.44-12.2, P = 0.009).

CONCLUSION

These results suggest that eGFRcys could estimate renal function and predict outcome more accurately compared with Cr-based eGFR in cirrhotic patients.

Systematic review with meta-analysis: self-expanding metal stents in patients with cirrhosis and severe or refractory oesophageal variceal bleeding

BACKGROUND

The prognosis of patients with cirrhosis and acute variceal bleeding is very poor when the standard-of-care fails to control bleeding. New treatment modalities are needed in these patients.

AIM

To synthesise the available evidence on the efficacy of self-expanding metal stents (SEMS) in patients with cirrhosis and severe or refractory oesophageal variceal bleeding.

METHODS

Meta-analysis of trials evaluating SEMS in patients with cirrhosis and severe or refractory oesophageal variceal bleeding.

RESULTS

Thirteen studies were included. The pooled estimate rates were 0.40 (95% confidence interval, CI = 0.31-0.49) for death, 0.41 (95% CI = 0.29-0.53) for liver-related death and 0.36 (95% CI = 0.26-0.47) for death at day 30, with low heterogeneity between studies. The pooled estimate rates were 0.12 (95% CI = 0.07-0.21) for mortality related to variceal bleeding, and 0.18 (95% CI = 0.11-0.29) for failure to control bleeding with SEMS, with no or low heterogeneity between studies. The pooled estimate rate were 0.16 (95% CI = 0.04-0.48) for rebleeding after stent removal and 0.28 (95% CI = 0.17-0.43) for stent migration, with high heterogeneity. A significant proportion of patients had access to liver transplantation or to TIPSS [pooled estimate rate 0.10 (95% CI = 0.04-0.21) and 0.26 (95% CI = 0.18-0.36), respectively].

CONCLUSIONS

Fewer than 40% of patients treated with SEMS were dead at 1 month. SEMS can be used as a bridge to TIPSS or to liver transplantation in a significant proportion of patients. Additional studies are required to identify potential risk factors leading to a poor prognosis in patients with acute variceal bleeding in whom the use of SEMS could be considered.

Effects of acute kidney injury on clinical outcomes in patients with upper gastrointestinal bleeding

AIM

Upper gastrointestinal bleeding (UGIB) is a very frequently encountered condition that has a high morbidity and which increases treatment costs. Duration of hospital stay and mortality increases in patients with UGIB complicated by acute kidney injury (AKI). The aim of this study was to reveal risk factors in patients with UGIB developing AKI and to compare clinical outcomes and hospital costs between patients with UGIB developing AKI and those with UGIB not developing AKI.

MATERIAL AND METHODS

This retrospective study included 245 patients admitted to the emergency unit and the intensive care unit for internal diseases at Ankara Numune Education and Research Hospital, Turkey.

RESULTS

The difference in mortality rates between the patients with AKI and those without AKI was significant (p < 0.001). The mean duration of intensive care unit stay was 0.2 ± 1.1 days in the patients without AKI (n = 143) and 2.5 ± 5.6 days in the patients with AKI. It was significantly higher in the patients with AKI (p < 0.001). Hospital stay was significantly longer in the patients with AKI than those without AKI, and as severity of AKI increased, hospital stay became considerably longer (p < 0.001). Hospital costs were significantly higher in the patients with AKI than those without AKI, and as severity of AKI increased, hospital costs considerably rose (p < 0.001).

CONCLUSION

AKI is a condition that lengthens hospital stay, increases hospital costs and creates a burden on health care systems. Detect kidney injury earlier and administering an appropriate treatment can improve clinical outcomes in patients with UGIB developing AKI.

Early transjugular intrahepatic portosystemic shunt in cirrhotic patients with acute variceal bleeding: a systematic review and meta-analysis of controlled trials

INTRODUCTION

There is conflicting evidence on the benefit of early transjugular intrahepatic portosystemic shunt (TIPSS) on the survival of patients with acute variceal bleeding (AVB).

AIM

To assess the effect of early TIPSS on patient prognosis.

MATERIALS AND METHODS

We carried out a meta-analysis of trials evaluating early TIPSS in cirrhotic patients with AVB.

RESULTS

Four studies were included. Early TIPSS was associated with fewer deaths [odds ratio (OR)=0.38, 95% confidence interval (CI)=0.17-0.83, P=0.02], with moderate heterogeneity between studies (P=0.15, I=44%). Early TIPSS was not significantly associated with fewer deaths among Child-Pugh B patients (OR=0.35, 95% CI=0.10-1.17, P=0.087) nor among Child-Pugh C patients (OR=0.34, 95% CI=0.10-1.11, P=0.074). There was no heterogeneity between studies in the Child-Pugh B analysis (P=0.6, I=0%), but there was a high heterogeneity in the Child-Pugh C analysis (P=0.06, I=60%). Early TIPSS was associated with lower rates of bleeding within 1 year (OR=0.08, 95% CI=0.04-0.17, P<0.001) both among Child-Pugh B patients, (OR=0.15, 95% CI=0.05-0.47, P=0.001) and among Child-Pugh C patients (OR=0.05, 95% CI=0.02-0.15, P<0.001), with no heterogeneity between studies. Early TIPSS was not associated with higher rates of encephalopathy (OR=0.84, 95% CI=0.50-1.42, P=0.5).

CONCLUSION

Cirrhotic patients with AVB treated with early TIPSS had lower death rates and lower rates of clinically significant bleeding within 1 year compared with patients treated without early TIPSS. Additional studies are required to identify the potential risk factors leading to a poor prognosis after early TIPSS in patients with AVB and to determine the impact of the degree of liver failure on the patient's prognosis.

Vitamin K for upper gastrointestinal bleeding in people with acute or chronic liver diseases

BACKGROUND

Upper gastrointestinal bleeding is one of the most frequent causes of morbidity and mortality in the course of liver cirrhosis. Several treatments are used for upper gastrointestinal bleeding in people with liver diseases. One of them is vitamin K administration, but it is not known whether it benefits or harms people with acute or chronic liver disease and upper gastrointestinal bleeding. This is an update of this Cochrane review.

OBJECTIVES

To assess the beneficial and harmful effects of vitamin K for people with acute or chronic liver disease and upper gastrointestinal bleeding.

SEARCH METHODS

We searched The Cochrane Hepato-Biliary Controlled Trials Register (February 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 2 of 12, 2015), MEDLINE (Ovid SP) (1946 to February 2015), EMBASE (Ovid SP) (1974 to February 2015), Science Citation Index EXPANDED (1900 to February 2015), and LILACS (1982 to 25 February 2015). We sought additional randomised trials from two registries of clinical trials: the World Health Organization Clinical Trials Search Portal and the metaRegister of Controlled Trials. We looked through the reference lists of the retrieved publications and review articles.

SELECTION CRITERIA

Randomised clinical trials irrespective of blinding, language, or publication status for assessment of benefits and harms. We considered observational studies for assessment of harms only.

DATA COLLECTION AND ANALYSIS

\We aimed to summarise data from randomised clinical trials using Standard Cochrane methodology and assess them according to the GRADE approach.

MAIN RESULTS

We found no randomised trials on vitamin K for upper gastrointestinal bleeding in people with liver diseases assessing benefits and harms of the intervention. We identified no quasi-randomised studies, historically controlled studies, or observational studies assessing harms.

AUTHORS' CONCLUSIONS

This updated review found no randomised clinical trials of vitamin K for upper gastrointestinal bleeding in people with liver diseases. The benefits and harms of vitamin K need to be tested in randomised clinical trials. Until randomised clinical trials are conducted to assess the trade-off between benefits and harms, we cannot recommend or refute the use of vitamin K for upper gastrointestinal bleeding in people with liver diseases.

Predictors of in-hospital mortality among patients presenting with variceal gastrointestinal bleeding

BACKGROUND/AIM

The recent years have witnessed an increase in number of people harboring chronic liver diseases. Gastroesophageal variceal bleeding occurs in 30% of patients with cirrhosis, and accounts for 80%-90% of bleeding episodes. We aimed to assess the in-hospital mortality rate among subjects presenting with variceal gastrointestinal bleeding and (2) to investigate the predictors of mortality rate among subjects presenting with variceal gastrointestinal bleeding.

PATIENTS AND METHODS

This retrospective study was conducted from treatment records of 317 subjects who presented with variceal upper gastrointestinal bleeding to Government Medical College, Patiala, between June 1, 2010, and May 30, 2014. The data thus obtained was compiled using a preset proforma, and the details analyzed using SPSSv20.

RESULTS

Cirrhosis accounted for 308 (97.16%) subjects with bleeding varices, with extrahepatic portal vein obstruction 9 (2.84%) completing the tally. Sixty-three (19.87%) subjects succumbed to death during hospital stay. Linear logistic regression revealed independent predictors for in-hospital mortality, including higher age (P = 0.000), Child-Pugh Class (P = 0.002), altered sensorium (P = 0.037), rebleeding within 24 h of admission (P = 0.000), low hemoglobin level (P = 0.023), and serum bilirubin (P = 0.002).

CONCLUSION

Higher age, low hemoglobin, higher Child-Pugh Class, rebleeding within 24 h of admission, higher serum bilirubin, and lower systolic blood pressure are the independent predictors of in-hospital mortality among subjects presenting with variceal gastrointestinal bleeding.

Risk factors for early rebleeding and mortality in acute variceal hemorrhage

AIM: To investigate the risk factors for 6-wk rebleeding and mortality in acute variceal hemorrhage (AVH) patients treated by percutaneous transhepatic variceal embolization (PTVE).

METHODS: A retrospective cohort study of AVH patients who had undergone PTVE treatment was conducted between January 2010 and December 2012. Demographic information, medical histories, physical examination findings, and laboratory test results were collected. The PTVE procedure was performed as a rescue therapy for patients who failed endoscopic and pharmacologic treatment. Survival analysis was estimated using the Kaplan-Meier method and compared using the log-rank test. The multivariate analysis was performed using the Cox regression test to identify independent risk factors for rebleeding and mortality.

RESULTS: One hundred and one patients were included; 71 were males and the average age was 51 years. Twenty-one patients rebled within 6 wk. Patients with high-risk stigmata, PTVE with trunk obliteration, and a hepatic vein pressure gradient (HVPG) ≥ 20 mmHg were at increased risk for rebleeding (OR = 5.279, 95%CI: 2.782-38.454, P = 0.003; OR = 4.309, 95%CI: = 2.144-11.793, P < 0.001; and OR = 1.534, 95%CI: 1.062-2.216, P = 0.022, respectively). Thirteen patients died within 6 wk. A model for end-stage liver disease (MELD) score ≥ 18 and an HVPG ≥ 20 mmHg were associated with 6-wk mortality (OR = 2.162, 95%CI: 1.145-4.084, P = 0.017 and OR = 1.423, 95%CI: 1.222-1.657, P < 0.001, respectively).

CONCLUSION: MELD score and HVPG in combination allow for early identification of patients with AVH who are at substantially increased risk of death over the short term.

Liver resection for HCC: patient's selection and controversial scenarios

Liver resection is a valuable curative option for patients with hepatocellular carcinoma (HCC). Yet, the balance between the operative risk following hepatectomy for HCC occurring on chronic liver disease and the oncologic prognosis of advanced lesions have led treatment recommendations to limiting the place of liver resection to selected patients with preserved liver function harbouring early-stage tumours. However, better understanding of the natural history of both tumour and underlying liver disease, sophisticated assessment of the liver function, improvements in the preoperative management of the patients with the use of liver volume modulation, refinements in surgical technique including anatomic resection and laparoscopic approach along with tailored management of recurrences have led expert centres to better define and extend the indications for liver resection. In this setting, the reported favourable operative results and long-term outcomes following resection of HCC in a number of controversial scenarios support that current guidelines could be refined.

Predictors of negative intraoperative findings at emergent laparotomy in patients with cirrhosis

BACKGROUND

Emergent surgery in the setting of decompensated cirrhosis is highly morbid. We sought to determine the clinical factors associated with negative intraoperative findings at emergent laparotomy.

METHODS

We performed a retrospective cohort study of consecutive inpatients with a diagnosis of cirrhosis (ICD-9 571) admitted to the Beth Israel Deaconess Medical Center (Boston, MA) who underwent emergent, nonhepatic, abdominal surgery between May 6, 2005 and September 3, 2012.

RESULTS

Eighty-six patients with cirrhosis were included with a mean model for end-stage liver disease score of 21.3 ± 7.95 and a 90-day mortality rate of 39.5%. Twelve (16.2%) patients had negative laparotomies. Negative intraoperative findings were independently associated with (1) paracentesis prior to a preoperative diagnosis of perforated viscus (P = 0.006), (2) development of an indication for emergent surgery after 24 h into hospital admission for another reason (P = 0.020), and (3) a preoperative diagnosis of bowel ischemia (P = 0.005), with odds ratios of 10.1 (CI 1.92-66.83), 5.80 (CI 1.32-33.39), and 11.1 (CI 2.08-77.4), respectively. Free air on computed tomography (CT) imaging was found in 64.3% (9/14) of patients who had a paracentesis within the preceding 48 h compared to 10.1% (7/72) among patients who did not undergo a paracentesis (P < 0.001). Only 45% of patients with free air following a paracentesis had positive findings at laparotomy compared to 100% in those without a preceding paracentesis (P = 0.038). Negative laparotomy was independently predictive of in-hospital mortality (OR 4.7; P = 0.034).

CONCLUSION

The possibility of a negative laparotomy is suggested by preoperative clinical factors. In particular, free air following a paracentesis does not necessarily indicate that operative intervention is required. Consideration of close observation before laparotomy in these patients is reasonable.

A risk scoring system to predict in-hospital mortality in patients with cirrhosis presenting with upper gastrointestinal bleeding

GOALS

We aimed to develop a simple and practical risk scoring system to predict in-hospital mortality in cirrhotics presenting with upper gastrointestinal (GI) bleeding.

STUDY

Extensive clinical data were captured in patients with documented cirrhosis who underwent endoscopic evaluation for upper GI bleeding between January 1, 2003 and June 30, 2011 at Parkland Memorial Hospital. Predictors of mortality were identified by multivariate regression analysis.

RESULTS

A total of 884 patients with cirrhosis admitted for upper GI bleeding were identified; 809 patients survived and 75 died (8.4%). The etiology of bleeding was similar in both groups, with bleeding attributed to esophageal varices in 59% of survivors and 60% of non-survivors (ulcer disease and other etiologies of bleeding accounted for the other causes of bleeding). Mortality was 8.6% and 8.3% in patients with variceal bleeding and nonvariceal bleeding, respectively. While survivors and those who died were similarly matched with regard to gender, age, ethnicity and etiology of cirrhosis, patients who died had lower systolic blood pressures, higher pulse rates and lower mean arterial pressures at admission than patients who survived. Non-survivors were more likely to be Childs C (61% vs. 19%, P<0.001). Multivariate regression analysis identified the following 4 predictors of in-hospital mortality: use of vasoactive pressors, number of packed red blood cells transfused, model for end-stage liver disease (MELD) score, and serum albumin. A receiver operating characteristic curve including these 4 variables yielded an area under the receiver operating characteristic (AUROC) curve of 0.94 (95% confidence interval, 0.91-0.98). Classification and Regression Tree analysis yielded similar results, identifying vasoactive pressors and then MELD>21 as the most important decision nodes for predicting death. By comparison, using the Rockall scoring system in the same patients, the AUROC curve was 0.70 (95% confidence interval, 0.64-0.76 and the comparison of the University of Texas Southwestern model to the Rockall model revealed P<0.0001). A validation set comprised of 150 unique admissions between July 1, 2011 and July 31, 2012, had an AUROC of 0.92, and the outcomes of 97% of the subjects in this set were accurately predicted by the risk score model.

CONCLUSIONS

Use of vasoactive agents, packed red blood cell transfusion, albumin, and MELD score were highly predictive of in-hospital mortality in cirrhotics presenting with upper GI bleeding. These variables were used to formulate a clinical risk scoring system for in-hospital mortality, which is available at: http://medweb.musc.edu/LogisticModelPredictor.

Enucleation-induced rat adrenal gland regeneration: expression profile of selected genes involved in control of adrenocortical cell proliferation

Enucleation-induced adrenal regeneration is a highly controlled process; however, only some elements involved in this process have been recognized. Therefore, we performed studies on regenerating rat adrenals. Microarray RNA analysis and QPCR revealed that enucleation resulted in a rapid elevation of expression of genes involved in response to wounding, defense response, and in immunological processes. Factors encoded by these genes obscure possible priming effects of various cytokines on initiation of regeneration. In regenerating adrenals we identified over 100 up- or downregulated genes involved in adrenocortical cell proliferation. The changes were most significant at days 2-3 after enucleation and their number decreased during regeneration. For example, expression analysis revealed a notable upregulation of the growth arrest gene, Gadd45, only 24 hours after surgery while expression of cyclin B1 and Cdk1 genes was notably elevated between days 1-8 of regeneration. These changes were accompanied by changes in expression levels of numerous growth factors and immediate-early transcription factors genes. Despite notable differences in mechanisms of adrenal and liver regeneration, in regenerating adrenals we identified genes, the expression of which is well recognized in regenerating liver. Thus, it seems legitimate to suggest that, in the rat, the general model of liver and adrenal regeneration demonstrate some degree of similarity.

A revised scope in different prognostic models in cirrhotic patients: Current and future perspectives, an Egyptian experience

BACKGROUND AND STUDY AIM

The prognosis of cirrhosis is of great interest for liver transplantation and new therapies of related complications. Traditional prognostic models such as Child-Pugh (CP) and Model for End-stage Liver Disease (MELD) were developed to predict mortality in decompensated cirrhosis, but lack parameter(s) related to complications. Recently, new models such as creatinine-modified Child-Turcotte-Pugh (CrCTP) and sodium-based MELD variants were developed to improve prognostic accuracy and enhance outcome predictive capability. Our aim was to investigate the prognostic ability of these models and their relation to complications among Egyptian cirrhotic patients to determine the best one and to assess adding new variables to improve the prognostic ability of that model.

PATIENTS AND METHODS

A total of 1000 cirrhotic patients were enrolled in a retrospective study; traditional and new prognostic models such as CP, MELD, CrCTP, integrated MELD (iMELD), MELD plus sodium (MELD-Na, MELDNa) and MELD:sodium ratio (MESO) were calculated. The predictive abilities of prognostic models were compared using the area under receiver operating characteristic curve (AUC) and 1-year survival rates were evaluated by Kaplan-Meier survival analysis. An index of cirrhosis-related complications was added to reveal the best prognostic model.

RESULTS

Using AUC, MELD and its sodium variants was significantly better than CP and CrCTP scores in predicting risk of 1-year mortality, where MELD-sodium (MELD-Na) had the highest AUC (0.743). Adding an index of cirrhosis-related complications (C) to MELD-Na creating a new scoring system (MELD-Na-C) improved its prognostic accuracy (AUC 0.753). Kaplan-Meier survival curves predicted increased mortality with higher prognostic scores.

CONCLUSIONS

All prognostic models were good predictors of 1-year mortality in patients with decompensated cirrhosis; however, MELD-Na was the best for outcome prediction. MELD-Na-C was a new model enhancing the predictive accuracy in assessing cirrhotic patients with related complications.

Model for End-Stage Liver Disease and liver cirrhosis-related complications

The Model for End-Stage Liver Disease (MELD) score has gained wide acceptance for predicting survival in patients undergoing liver transplantation. The strength of this score remains in the mathematical formula derived from a multivariate Cox regression analysis; it is a continuous scale and lacks a ceiling or a floor effect with a wide range of discrimination. It is based on objective, reproducible, and readily available laboratory data and the wide range of samples which have been validated. Liver cirrhosis complications such as ascites, encephalopathy, spontaneous bacterial peritonitis and variceal bleeding were not considered in the MELD score underestimating their direct association with the severity of liver disease. In this regard, several recent studies have shown that clinical manifestations secondary to portal hypertension are good prognostic markers in cirrhotic patients and may add additional useful prognostic information to the current MELD. We review the feasibility of MELD score as a prognostic predictor in patients with liver cirrhosis-related complications.
