ABSTRACT: Background
The effect of acute kidney injury (AKI) on patients with acute variceal bleeding (AVB) using the recently proposed International Club of Ascites (ICA) criteria is unclear. This study aimed to evaluate the incidence of AKI using the ICA criteria and factors associated with the outcomes in cirrhotic patients with AVB.Methods
This retrospective cohort study included data of cirrhotic patients with AVB from two centers in Korea. The association of the ICA criteria for AKI with 6-week mortality was analyzed through univariate and multivariate analyses using the Cox proportional hazard model.Results
In total, there were 546 episodes of AVB in 390 patients, of which 425 and 121 episodes were due to esophageal and gastric variceal bleeding, respectively. Moreover, 153 patients fulfilled the ICA criteria for AKI, and 64, 30, 39, and 20 patients were diagnosed with stages 1a, 1b, 2, and 3, respectively. Conversely, 97 patients developed AKI within 42 days as per the conventional criteria. The 6-week mortality rate was significantly higher in patients with ICA-AKI than in patients without ICA-AKI; the occurrence of ICA-AKI was an independent factor for predicting the 6-week mortality.Conclusion
The ICA criteria could help diagnose renal dysfunction earlier, and presence of AKI is a predictor of mortality in patients with cirrhosis and AVB.

Project description:Background/aimsThis study examined the risk factors associated with mortality in cirrhotic patients hospitalized with variceal bleeding, and evaluated the effects of acute-on-chronic liver failure (ACLF) on the prognosis of these patients.MethodsThis study was retrospectively conducted on patients registered in the Korean acute-on-chronic liver failure study cohort, and on 474 consecutive cirrhotic patients hospitalized with variceal bleeding from January 2013 to December 2013 at 21 university hospitals. ACLF was defined as described by the European Association for the Study of Liver-Chronic Liver Failure Consortium.ResultsAmong a total of 474 patients, 61 patients were diagnosed with ACLF. The cumulative overall survival (OS) rate was lower in the patients with ACLF than in those without (P<0.001), and patients with higher ACLF grades had a lower OS rate (P<0.001). The chronic liver failure-sequential organ failure assessment (CLIF-SOFA) score was identified as a significant prognostic factor in patients hospitalized with variceal bleeding (hazard ratio [HR], 1.40; 95% confidence interval [CI], 1.30-1.50; P<0.001), even in ACLF patients with variceal bleeding (HR, 1.32; 95% CI, 1.19-1.46, P<0.001). Concerning the prediction of the mortality risk at 28- and 90-day using CLIF-SOFA scores, c-statistics were 0.895 (95% CI, 0.829-0.962) and 0.897 (95% CI, 0.842-0.951), respectively, and the optimal cut-off values were 6.5 and 6.5, respectively.ConclusionIn cirrhotic patients hospitalized with variceal bleeding, the prognosis was poor when accompanied by ACLF, especially depending upon CLIF-SOFA score. CLIF-SOFA model well predicted the 28-day or 90-day mortality for cirrhotic patients who experienced variceal bleeding.

Project description:Background/purposeRisk factors for re-bleeding and death after acute variceal bleeding (AVB) in cirrhotic HCC patients are not fully understood.We aimed to (1) explore how the combination of high-risk esophageal varices, HCC status, and portal vein tumor thrombus (i.e., HCC Portal Hypertension Imaging Score [HCCPHTIS]) helps predict increased risk of variceal re-bleeding and mortality; (2) assess predictability and reproducibility of the identified variceal re-bleeding rules.MethodsThis prospective study included 195 HCC patients with first-time AVB and liver cirrhosis, and conducted multivariable Cox regression analysis and Kaplan-Meier analysis. Receiver operating characteristic curve analysis was calculated to find the optimal sensitivity, specificity, and cutoff values of the variables. The reproducibility of the results obtained was verified in a different but related group of patients.Results56 patients (28.7%) had re-bleeding within 6 weeks; HCCPHTIS was an independent risk factor for variceal re-bleeding after AVB (Odd ratio, 2.330; 95% confidence interval: 1.728-3.142, p < 0.001). The positive predictive value of HCCPHTIS cut off value > 3 was 66.2%, sensitivity 83.9%, and specificity 82.3%. HCCPHTIS area under the curve was higher than Child-Pugh score (89% vs. 75%, p < 0.001). 74(37.9%) death occurred within 6 weeks; HCCPHTIS > 4 was associated with increased risk of death within 6 weeks after AVB (p < 0.001).ConclusionHCCPHTIS > 3 is a strong predictor of variceal re-bleeding within the first 6 weeks. However, patients with HCCPHTIS > 4 were at increased risk of death within 6 weeks.

Project description:Modification of the mortality risk associated with acute kidney injury (AKI) necessitates recognition of AKI when it occurs. We sought to determine whether formal documentation of AKI in the medical record, assessed by billing codes for AKI, would be associated with improved clinical outcomes.Retrospective cohort study conducted at three hospitals within a single university health system. Adults without severe underlying kidney disease who suffered in-hospital AKI as defined by a doubling of baseline creatinine (n = 5,438) were included. Those whose AKI was formally documented according to discharge billing codes were compared to those without such documentation in terms of 30-day mortality.Formal documentation of AKI occurred in 2,325 patients (43%). Higher baseline creatinine, higher peak creatinine, medical admission status, and higher Sequential Organ Failure Assessment (SOFA) score were strongly associated with documentation of AKI. After adjustment for severity of disease, formal AKI documentation was associated with reduced 30-day mortality - OR 0.81 (0.68 - 0.96, p = 0.02). Patients with formal documentation were more likely to receive a nephrology consultation (31% vs. 6%, p < 0.001) and fluid boluses (64% vs. 45%, p < 0.001), and had a more rapid discontinuation of angiotensin-converting enzyme inhibitor and angiotensin-receptor blocker medications (HR 2.04, CI 1.69 - 2.46, p < 0.001).Formal documentation of AKI is associated with improved survival after adjustment for illness severity among patients with creatinine-defined AKI.

Project description:The objective of this study was to determine the incidence of acute kidney injury (AKI) and its relation with mortality among hospitalized patients.Analysis of hospital discharge and laboratory data from an urban academic medical center over a 1-year period. We included hospitalized adult patients receiving two or more serum creatinine (sCr) measurements. We excluded prisoners, psychiatry, labor and delivery, and transferred patients, 'bedded outpatients' as well as individuals with a history of kidney transplant or chronic dialysis. We defined AKI as (a) an increase in sCr of ?0.3 mg/dl; (b) an increase in sCr to ?150% of baseline, or (c) the initiation of dialysis in a patient with no known history of prior dialysis. We identified factors associated with AKI as well as the relationships between AKI and in-hospital mortality.Among the 19,249 hospitalizations included in the analysis, the incidence of AKI was 22.7%. Older persons, Blacks, and patients with reduced baseline kidney function were more likely to develop AKI (all p < 0.001). Among AKI cases, the most common primary admitting diagnosis groups were circulatory diseases (25.4%) and infection (16.4%). After adjustment for age, sex, race, admitting sCr concentration, and the severity of illness index, AKI was independently associated with in-hospital mortality (adjusted odds ratio 4.43, 95% confidence interval 3.68-5.35).AKI occurred in over 1 of 5 hospitalizations and was associated with a more than fourfold increased likelihood of death. These observations highlight the importance of AKI recognition as well as the association of AKI with mortality in hospitalized patients.

Project description:Background and aimAcute variceal bleeding (AVB) is a serious complication associated with high mortality. The aim of our study was to investigate mortality predictors and to develop a new simplified prognostic model among cirrhotic patients with AVB.MethodsA simplified prognostic model was developed using multiple logistic regression after identifying significant predictors of 6-week mortality.ResultsA total of 713 consecutive patients with AVB were enrolled. The 6-week overall mortality rate was 18%. Multivariate analysis showed that shock, model for end-stage liver disease (MELD) score, high-risk stigmata of esophageal varices on endoscopic finding, and Glasgow Blatchford score were independent predictors of mortality. A new logistic model using these variables was developed. This model (cutoff value ≥ 4) area under the receiver operating characteristics (AUROC) was 0.93 and significantly higher than that of MELD score alone (0.74). Two validation analyses showed that the AUROC of our model was consistently high. The 6-week rebleeding rate was 25.3%. Multivariate analysis showed that MELD score, Glasgow Blatchford score, history of upper GI bleeding, shock, and alcohol use were independent predictors of rebleeding.ConclusionOur new simplified model accurately and consistently predicted 6-week mortality among patients with AVB using objective variables measured at admission. Patients with higher MELD scores should be closely monitored due to the higher probability of 6-week rebleeding.

Project description:This study aimed to test the safety and efficacy of Hemospray® for emergency control of acute variceal bleeding (AVB) due to portal hypertension in cirrhotic patients.This single-arm, prospective trial, conducted at two hospitals in Belgium and Egypt, included patients admitted to the emergency room with hematemesis and/or melena and known or suspected liver cirrhosis. All patients received urgent hemodynamic stabilization, octreotide (50 mcg bolus then 25?mcg/hour for 24 hours) and intravenous ceftriaxone (1?g/hour). Endoscopy to confirm AVB and Hemospray® application (if indicated) was performed within six hours of admission. Patients were kept under observation for 24 hours and underwent second endoscopy and definitive therapy (band ligation and/or cyanoacrylate injection in cases of gastric varices) the next day.Thirty-eight patients were admitted for suspected AVB, and 30 of these had confirmed AVB (70% male; mean age 59.5 years (range, 32.0-73 years)). Child-Pugh class C liver disease was present in 53.4%. Esophageal varices were observed in 83.4% of patients, gastric varices in 10%, and duodenal varices in 6.6%. Spurting bleeding at the time of endoscopy was observed in 43.4%. One patient developed hematemesis six hours after Hemospray® application and underwent emergency endoscopic band ligation. No major adverse events or mortalities were observed during 15-day follow-up.Hemospray® application was safe and effective at short-term follow-up for emergency treatment of AVB in cirrhotic patients.

Project description:AbstractIn upper gastrointestinal bleeding (UGIB), scoring systems using multiple variables were developed to predict patient outcomes. We evaluated serum C-reactive protein (CRP) for simple prediction of patient mortality after acute non-variceal UGIB.The associated factors for 30-day mortality was investigated by regression analysis in patients with acute non-variceal UGIB (N = 1232). The area under the receiver operating characteristics (AUROC) curve was analyzed with serum CRP in these patients and a prospective cohort (N = 435). The discriminant validity of serum CRP was compared to other prognostic scoring systems by means of AUROC curve analysis.Serum CRP was significantly higher in the expired than survived patients (median, 4.53 vs 0.49; P < .001). The odds ratio of serum CRP was 4.18 (2.10-9.27) in multivariate analysis. The odds ratio of high serum CRP was higher than Rockall score (4.15 vs 1.29), AIMS65 (3.55 vs 1.71) and Glasgow-Blatchford score (4.32 vs 1.08) in multivariate analyses. The AUROC of serum CRP at bleeding was 0.78 for 30-day mortality (P < .001). In the validation set, serum CRP was also significantly higher in the expired than survived patients, of which AUROC was 0.73 (P < .001). In predicting 30-day mortality, the AUROC with serum CRP was not inferior to that of other scoring systems.Serum CRP at bleeding can be simply used to identify the patients with high mortality after acute non-variceal UGIB.

Project description:Blood transfusion remains an integral step in the management of acute non-variceal upper gastrointestinal bleeding (NV-UGIB), but its safety is being increasingly questioned in less severe cases. The authors aimed to measure 30-day and 2-year mortalities after blood transfusion for NV-UGIB.Cox proportional hazards models were used to estimate the association of blood transfusion with mortality while adjusting for age, Charlson comorbidity score, the complete Rockall score for acute UGIB, admission status and medication intake prior to bleeding.Death from any cause at 30 days and 2 years after NV-UGIB.1340 patients presented with NV-UGIB< (808 men (60.3%), median age 67 years) of whom 564 (42.1%) were transfused. The overall mortality was 5.3% at 30 days and 26.0% at 2 years in all patients. Comparing subjects with a haemoglobin concentration greater than 10.0 g/dl who were transfused with those who were not, 30-day mortalities (95% CIs) were 11.5% (6.7 to 18.0) versus 3.6% (2.3 to 5.3), respectively, p<0.001, and 2-year mortalities (95% CIs) were 40% (32 to 49) versus 20% (17 to 23), p<0.001. After adjusting for age, Charlson score, Rockall score and haemoglobin, the HRs (95% CIs) for death after transfusion were 1.88 (1.00 to 3.55) (p=0.051) at 30 days and 1.71 (1.28 to 2.28), (p<0.001) at 2 years.In patients with moderately severe NV-UGIB, mortality is higher following blood transfusion. Whether this reflects selection bias, an effect of comorbidity or an effect of transfusion requires urgent prospective study.

Project description:Background and aimEarly transjugular intrahepatic portosystemic shunt (TIPS) used as preventive therapy prior to recurrent bleeding has been recommended in patients presenting with acute esophageal variceal bleeding (EVB) who are at high risk of further bleeding and death. We investigated the impact of early TIPS on outcomes of US patients hospitalized with EVB from 2000 to 2010.MethodsThe Nationwide Inpatient Sample database was queried to identify patients with EVB and decompensated cirrhosis (because early TIPS is recommended only in high-risk patients). The primary outcome was in-hospital death, and secondary outcomes included rebleeding and hepatic encephalopathy. Early preventive TIPS was defined by placement within 3 days of hospitalization for acute EVB after one session of endoscopic therapy. Rescue TIPS was defined as TIPS after two interventions for EVB.ResultsThe study included 142 539 patients. From 2000 to 2010, the age-adjusted in-hospital mortality rate decreased 37.2% from 656 per 100 000 to 412 per 100 000 (P <0.01), while early and rescue TIPS increased (0.22% to 0.70%; P < 0.01 and 1.1% to 6.1%; P < 0.01). On multivariate analysis, as compared with no TIPS, early TIPS was associated with decreased inpatient mortality (risk ratio [RR] = 0.87; 95% confidence interval [CI], 0.84-0.90) and rebleeding (RR = 0.56; 95% CI, 0.45-0.71) without an increase in hepatic encephalopathy (RR = 1.01; 95% CI, 0.93-1.11).ConclusionEarly preventive TIPS in patients with EVB and decompensated cirrhosis was associated with significant in-hospital reductions in rebleeding and mortality without a significant increase in encephalopathy in "real-world" US clinical practice.

Project description:Background/aimsThe treatment outcomes and prognostic markers of acute variceal bleeding (AVB) in hepatocellular carcinoma (HCC) patients remain unclear. Therefore, we evaluated the clinical outcomes and prognostic factors of AVB in HCC patients.MethodsCirrhotic patients with endoscopically confirmed AVB between 2007 and 2013 were enrolled in this prospective study. Prognostic factors were identified by multivariate Cox proportional hazards regression analysis.ResultsAmong the 329 enrolled patients, 125 patients (38.0%) were diagnosed with HCC. The 6-week mortality rates of all enrolled AVB patients and the HCC subgroup were 14.9% and 26.4%. The 5-day treatment failure, 6-week mortality, cirrhosis-related complications, and duration of hospitalization were greater in HCC patients than in non-HCC patients (all p<0.05). In the HCC subgroup, the Model for End-Stage Liver Disease (MELD) score (hazard ratio [HR], 1.145; p=0.001) and Barcelona Clinic Liver Cancer (BCLC) stage (C-D vs 0-B) (HR, 3.096; p=0.019) were independent predictors of 6-week mortality. Our study revealed that 85% of HCC patients with both a MELD score ≥15.5 and BCLC stage C-D died within 6 weeks, and the 6-week mortality risk was 21-fold higher in this group than in the group with a lower MELD score and earlier HCC stage (p<0.001).ConclusionsThe 5-day treatment failure and 6-week mortality rates were significantly higher among AVB patients with HCC than those without HCC. The MELD score and the presence and stage of HCC are strong predictors of 6-week mortality in patients with AVB.
