Peptic ulcer bleeding in patients with or without cirrhosis: different diseases but the same prognosis?

Epidemiology of asymptomatic peptic ulcer disease diagnosed during screening endoscopy in patients with cirrhosis

OBJECTIVE

Asymptomatic peptic ulcer disease (PUD) is frequently overlooked in patients with cirrhosis, who are at increased risk for gastrointestinal complications that can lead to increased morbidity and mortality. We aimed to determine the prevalence and associated factors of asymptomatic PUD identified during screening endoscopy in patients with cirrhosis.

METHODS

We conducted a retrospective cross-sectional study among patients with cirrhosis at St. Paul's Hospital Millennium Medical College in Ethiopia. Data were collected using a structured questionnaire from patients' medical charts. A logistic regression model was used to identify predictors of peptic ulcer.

RESULTS

This study included 296 patients, revealing that 19.6% had PUD (95% confidence interval: 13.5-26.4). Significant associations were found between peptic ulcer and Helicobacter pylori infection, moderate and heavy alcohol consumption, and Child-Pugh class C cirrhosis.

CONCLUSION

We found that patients with liver cirrhosis are more likely to have asymptomatic peptic ulcers. Asymptomatic PUD was linked to H. pylori infection, greater alcohol consumption, and Child-Pugh class C liver disease, highlighting the need for targeted prevention and management strategies to reduce morbidity in patients with cirrhosis, such as eradication therapy for H. pylori and counseling on alcohol use.

Comparison of gastrointestinal bleeding in patients with and without liver cirrhosis

OBJECTIVES

Upper gastrointestinal bleeding (GIB) in patients has been well-characterized in liver cirrhosis but studies on lower GIB are limited. The clinical characteristics, management and outcomes in patients with and without liver cirrhosis was compared to determine the overall features of GIB in patients with liver cirrhosis compared with non-cirrhotics.

METHODS

A retrospective study on cirrhotics hospitalized for GIB 2010-2021, matched with control group of non-cirrhotics (1:4) for upper vs. lower GIB. Patients with overt bleeding leading to hospitalization were included.

RESULTS

Overall, 396 patients had cirrhosis, 267 (67%) men, median age 62, alcoholic etiology 177/396 (45%), median MELD 12 (range 6-32). Overall 102 cirrhotics had GIB, matched with 391 non-cirrhotics. Overall 87 (85%) cirrhotic patients had upper and 15% lower GIB. Compared to non-cirrhotics, the cause of GIB was more commonly acute variceal bleeding (AVB) (42% vs. 1%), hemorrhoids 40% vs. 6% (p = 0.002), less commonly gastric ulcer 13% vs. 31% (p < 0.001), duodenal ulcer 9% vs. 29% (p < 0.001), 5% of cirrhotics used NSAIDs vs. 26% of controls (p < 0.001). Rebleeding occurred in 14% of cirrhotics vs. 3% in controls (p < 0.001). Only one cirrhotic patient (1%) died from GIB vs. 0.8% of controls within 45 days. Overall mortality 45 days after hospitalization was 10% in cirrhotics vs. 5% in controls (p < 0.001).

CONCLUSIONS

Bleeding from gastric and duodenal ulcers were less common in cirrhotics than in controls. Bleeding from hemorrhoids was more common in cirrhotics. Mortality due to GIB was low in both groups but overall mortality was significantly higher in cirrhotics.

Impact of peptic ulcer bleeding on the in-hospital outcomes of cirrhotic patients with acute gastrointestinal bleeding: an international multicenter study

OBJECTIVES

Peptic ulcer is the most common source of non-variceal bleeding. However, it remains controversial whether the outcomes of cirrhotic patients with peptic ulcer bleeding differ from those with variceal bleeding.

METHODS

Cirrhotic patients with acute gastrointestinal bleeding (AGIB) who underwent endoscopy and had an identifiable source of bleeding were retrospectively screened from an international multicenter cohort. Logistic regression analyses were performed to explore the impact of peptic ulcer bleeding on in-hospital death and 5-day failure to control bleeding. Propensity score matching (PSM) analysis was performed by matching age, gender, Child-Pugh score, and model for end-stage liver disease score between the peptic ulcer bleeding and variceal bleeding groups.

RESULTS

Overall, 1535 patients were included, of whom 73 (4.7%) had peptic ulcer bleeding. Multivariate logistic regression analyses showed that peptic ulcer bleeding was not independently associated with in-hospital death (OR = 2.169, p = 0.126) or 5-day failure to control bleeding (OR = 1.230, p = 0.680). PSM analyses demonstrated that both in-hospital mortality (9.7% vs. 6.3%, p = 0.376) and rate of 5-day failure to control bleeding (6.9% vs. 5.4%, p = 0.787) were not significantly different between the two groups.

CONCLUSIONS

The impact of peptic ulcer bleeding on the in-hospital outcomes of cirrhotic patients is similar to that of variceal bleeding.

Liver Severity Score-Based Modeling to Predict Six-Week Mortality Risk Among Hospitalized Cirrhosis Patients With Upper Gastrointestinal Bleeding

Background

Patients with cirrhosis who have gastrointestinal bleeding have high short-term mortality, but the best modality for risk calculation remains in debate. Liver severity indices, such as Child-Turcotte-Pugh (CTP) and Model-for-End-Stage-Liver Disease (MELD) score, are well-studied in portal hypertensive bleeding, but there is a paucity of data confirming their accuracy in non-portal hypertensive bleeding and overall acute upper gastrointestinal bleeding (UGIB), unrelated to portal hypertension.

Aims

This study aims to better understand the accuracy of current mortality risk calculators in predicting mortality for patients with any type of UGIB, which could allow for earlier risk stratification and targeted intervention prior to endoscopy to identify the bleeding source.

Methods

In a large US single-center cohort, we investigated and recalibrated the model performance of CTP and MELD scores to predict six-week mortality risk for both sources of UGIB (portal hypertensive and non-portal hypertensive).

Results

Both CTP- and MELD-based models have excellent discrimination in predicting six-week mortality for all types of bleeding sources. However, only a CTP-based model demonstrates calibration for all bleeding, regardless of bleeding etiology. Median predicted 6-week mortality by CTP class A, B, and C estimates a risk of 1%, 7%, and 35% respectively.

Conclusions

Our study corroborates findings in the literature that CTP- and MELD-based models have similar discriminative abilities for predicting 6-week mortality in hospitalized cirrhosis patients presenting with either portal hypertensive or non-portal hypertensive UGIB. CTP class is an effective clinical decision tool that can be used, even prior to endoscopy, to accurately risk stratify a patient with known cirrhosis presenting with any UGIB into low, moderate, and severe risk groupings.

Sudden Death Caused by Gastroesophageal Varices Rupture: Insights From an Autopsy-Based Case Series Unraveling the Pathological Events

Sudden death is characterized by natural yet unexpected death, typically occurring within 24 hours from the onset of the patient's symptoms. While the majority of sudden deaths stem from cardiac issues/causes, there are instances where non-cardiac factors are at play. One such scenario involves hemorrhage from ruptured esophageal varices, a complication that stems from portal hypertension. Portal hypertension can manifest due to a range of pre-hepatic, hepatic, and post-hepatic conditions, with liver cirrhosis being the primary culprit. Although sudden death cases linked to the gastrointestinal system are relatively rare, the rupture of gastroesophageal varices, precipitating severe morbidity and a high mortality rate, represents a life-threatening condition. In this context, we present a case series encompassing five instances of sudden natural deaths arising from the rupture of gastroesophageal varices.

Endoscopic findings unrelated to portal hypertension in patients with liver cirrhosis undergoing a varicose vein screening programme

AIM

To determine the prevalence of endoscopic lesions unrelated with portal hypertension in patients with cirrhosis.

PATIENTS AND METHODS

Cross-sectional study including a consecutive cohort of patients with liver cirrhosis enrolled in a screening program of oesophageal varices who underwent an upper gastrointestinal endoscopy from November, 2013, to November, 2018. Clinical predictors of endoscopic lesions unrelated to portal hypertension were analyzed by univariate and multivariate logistic regression.

RESULTS

A total of 379 patients were included. The most frequent aetiology of liver disease was alcohol consumption (60.4%). The prevalence of endoscopic lesions unrelated with portal hypertension was 39.6% (n=150). Among 96 patients with peptic lesions, urease was obtained in 56.2% of patients (positive in 44.4% of them). The prevalence of endoscopic lesions unrelated to portal hypertension was not associated with age, gender, liver function or ultrasound findings of portal hypertension. The prevalence of endoscopic lesions unrelated to portal hypertension was not associated with age, gender, liver function or ultrasound findings of portal hypertension. Smokers had a trend to increased prevalence of endoscopic lesions unrelated to portal hypertension (43.2% vs. 34.6%; p=0.09), particularly peptic ulcer (6.4% vs. 0.6%; p=0.05) and peptic duodenitis (17.3% vs. 6.3%; p=0.002). Active smoking was the only independent predictor of peptic ulcer or duodenitis (OR=2.56; p=0.017).

CONCLUSION

Active smoking is a risk factor for endoscopic lesions unrelated to portal hypertension. This finding should be further investigated to reassess endoscopic screening programs in cirrhotic smokers.

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.

Association of ABO Blood Type with Bleeding Severity in Patients with Acute Gastroesophageal Variceal Bleeding

Background and Objectives: ABO blood types have been implicated as potential risk factors for various hemorrhagic diseases. No study has investigated the association between gastroesophageal variceal bleeding and ABO blood types. We aimed to evaluate the impact of ABO blood types on mortality and bleeding risk in acute gastroesophageal variceal bleeding. Materials and Methods: This is a retrospective observational study. Patients presenting with acute gastroesophageal varices bleeding diagnosed by endoscopy were enrolled, and were divided by blood type into a type O group and non-type O group. The outcomes were death within 30 days and the proportion of further bleeding. We used generalized linear mixed-effects models to analyze the outcomes. Results: A total of 327 patients and 648 records of emergency room visits were included. The 30-day mortality was 14.8% (21 of 142 patients) in the type O group, and 16.2% (30 of 185 patients) in the non-type O group (p = 0.532). Further bleeding within 30 days occurred in 34 cases (12.6%) in the type O group, and in 26 cases (6.9%) in the non-type O group (p = 0.539). Conclusions: There was no significant difference in blood transfusion volume in 24 h, recurrent bleeding rates, or mortality between patients with blood type O and those with non-type O.

Emergent Transjugular Intrahepatic Portosystemic Shunt Creation in Acute Variceal Bleeding

Emergent transjugular intrahepatic portosystemic shunt (TIPS) creation is most commonly employed in the setting of acute variceal hemorrhage. Given a propensity for decompensation, these patients often require a multidisciplinary, multimodal approach involving prompt diagnosis, pharmacologic therapy, and endoscopic intervention. While successful in the majority of cases, failure to medically control initial bleeding can prompt interventional radiology consultation for emergent portal decompression via TIPS creation. This article discusses TIPS creation in emergent, acute variceal hemorrhage, reviewing the natural history of gastroesophageal varices, presentation and diagnosis of acute variceal hemorrhage, pharmacologic therapy, endoscopic approaches, patient selection and risk stratification for TIPS, technical considerations for TIPS creation, adjunctive embolotherapy, and the role of salvage TIPS versus early TIPS in acute variceal hemorrhage.

Parallel transjugular intrahepatic portosystemic shunt with Viatorr® stents for primary TIPS insufficiency: Case series and review of literature

BACKGROUND

Transjugular intrahepatic portosystemic shunts (TIPS) can alleviate complications of portal hypertension such as ascites and variceal bleeding by decreasing the portosystemic gradient. In limited clinical situations, parallel TIPS may be only solution to alleviate either variceal bleeding or ascites secondary to portal hypertension when the primary TIPS fails to do so. Data specifically addressing the use of this partially polytetrafluoroethylene covered nitinol stent (Viatorr®) is largely lacking despite Viatorr® being the current gold standard for modern TIPS placement.

CASE SUMMARY

All three patients had portal hypertension and already had a primary Viatorr® TIPS placed previously. All patients have undergone failed endoscopy to manage acute variceal bleeding before referral for a parallel stent (PS). PS were placed in patients presenting with recurrent variceal bleeding despite existence of a widely patent primary TIPS. Primary stent patency was verified with either Doppler ultrasound or intra-procedural TIPS stent venography. Doppler ultrasound follow-up imaging demonstrated complete patency of both primary and parallel TIPS. All three patients did well on clinical follow-up of up to six months and no major complications were recorded. A review of existing literature on the role of PS in the management of portal hypertension complications is discussed. There are three case reports of use of primary and PS Viatorr® stents placement, only one of which is in a patient with gastrointestinal variceal bleeding despite a patent primary Viatorr® TIPS.

CONCLUSION

Viatorr® PS placement in the management of variceal hemorrhage is feasible with promising short term patency and clinical follow-up data.

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.

Survival of patients with cirrhosis and acute peptic ulcer bleeding compared with variceal bleeding using current first-line therapies

The presence of cirrhosis increases the mortality of patients with peptic ulcer bleeding (PUB). Both acute variceal bleeding (AVB) and PUB are associated with substantial mortality in cirrhosis. This multicenter cohort study was performed to assess whether the mortality of patients with cirrhosis with PUB is different from that of those with AVB. Patients with cirrhosis and acute gastrointestinal bleeding were consecutively included and treated with somatostatin and proton pump inhibitor infusion from admission and with antibiotic prophylaxis. Emergency endoscopy with endoscopic therapy was performed within the first 6 hours. 646 patients with AVB and 144 with PUB were included. There were baseline differences between groups, such as use of gastroerosive drugs or β-blockers. Child-Pugh and Model for End-Stage Liver Disease MELD scores were similar. Further bleeding was more frequent in the AVB group than those in the PUB group (18% vs. 10%; odds ratio [OR] = 0.50; 95% confidence interval [CI] = 0.29-0.88). However, mortality risk at 45 days was similar in both groups (19% in the AVB group vs. 17% in the PUB group; OR = 0.85; 95% CI = 0.55-1.33; P = 0.48). Different parameters, such as Child-Pugh score, acute kidney injury, acute on chronic liver failure, or presence of shock or bacterial infection, but not the cause of bleeding, were related to the risk of death. Only 2% of the PUB group versus 3% of the AVB group died with uncontrolled bleeding (P = 0.39), whereas the majority of patients in either group died from liver failure or attributed to other comorbidities.

CONCLUSION

Using current first-line therapy, patients with cirrhosis and acute peptic ulcer bleeding have a similar survival than those with variceal bleeding. The risk of further bleeding is higher in patients with variceal hemorrhage. However, few patients in both groups died from uncontrolled bleeding, rather the cause of death was usually related to liver failure or comorbidities. (Hepatology 2018;67:1458-1471).

Variceal bleeding in cirrhotic patients

Variceal bleeding is one of the major causes of death in cirrhotic patients. The management during the acute phase and the secondary prophylaxis is well defined. Recent recommendations (2015 Baveno VI expert consensus) are available and should be followed for an optimal management, which must be performed as an emergency in a liver or general intensive-care unit. It is based on the early administration of a vasoactive drug (before endoscopy), an antibiotic prophylaxis and a restrictive transfusion strategy (hemoglobin target of 7 g/dL). The endoscopic treatment is based on band ligations. Sclerotherapy should be abandoned. In the most severe patients (Child Pugh C or B with active bleeding during initial endoscopy), transjugular intrahepatic portosystemic shunt (TIPS) should be performed within 72 hours after admission to minimize the risk of rebleeding. Secondary prophylaxis is based on the association of non-selective beta-blockers (NSBBs) and repeated band ligations. TIPS should be considered when bleeding reoccurs in spite of a well-conducted secondary prophylaxis or when NSBBs are poorly tolerated. It should also be considered when bleeding is refractory. Liver transplantation should be discussed when bleeding is not controlled after TIPS insertion and in all cases when liver function is deteriorated.

Risk of Rebleeding and Mortality in Cirrhotic Patients with Peptic Ulcer Bleeding: A 12-Year Nationwide Cohort Study

Although a few studies have investigated the risks of peptic ulcer bleeding (PUB) in cirrhotic patients, large population-based studies on in-hospital and long-term reports on recurrent PUB in a cohort of cirrhotic patients are lacking. This 12-year nationwide cohort study aimed to investigate the risks of in-hospital and long-term rebleeding and mortality in cirrhotic patients and to identify possible risk factors. Patient data from 1997 to 2008 were extracted from the National Health Insurance Research Database in Taiwan. A total of 15,575 patients who were discharged with a diagnosis of PUB were identified after strict exclusions (n = 2889). Among them, patients with cirrhosis (n = 737) and those with chronic hepatitis (n = 1044) were compared to propensity-score matched normal controls at a ratio of 1:1. Accumulated in-hospital and long-term follow-up PUB-free survival rates were analyzed in patients with cirrhosis, patients with chronic hepatitis, and matched controls. Cox proportional hazards regression was used to identify each independent risk factor. Compared with matched controls, patients with cirrhosis exhibited a 2.62-fold (95% CI: 1.74–3.92) higher risk of developing in-hospital rebleeding, but the risk of long-term rebleeding was comparable between cirrhotic patients and matched controls (hazard ratio: 1.29, 95% CI: 0.8–2.09). On the other hand, no significant difference was observed in in-hospital and long-term rebleeding between chronic hepatitis patients and matched controls. We compared the survival rates of cirrhotic and chronic hepatitis patients to that of matched controls. After propensity score matching, both cirrhotic and chronic hepatitis patients showed significantly lower survival than the matched controls (P < 0.0001 and 0.033, respectively) during the 12-year follow-up period. However, in-hospital and long-term rebleeding rates were not significantly different between chronic hepatitis patients and matched controls (P = 0.251 and 0.474, respectively). In conclusion, liver cirrhosis increased health care expenses in patients with PUB and these patients exhibited higher recurrent bleeding rate than non-cirrhotic patients during hospitalization. Cirrhosis and chronic hepatitis are independently associated with an increased long-term mortality when compared with patients without liver disease.

Improving the management of gastrointestinal bleeding in patients with cirrhosis

Gastrointestinal bleeding remains a major cause of mortality in patients with cirrhosis. The most common source of bleeding is from gastroesophageal varices but non-variceal bleeding from peptic ulcer disease also carries a significant risk in patients with liver disease. The prognosis is related to the severity of the underlying liver disease, and deaths often occur due to liver failure, infection or renal failure. Optimal management should therefore not only achieve haemostasis but address these complications as well. The management of gastrointestinal bleeding in patients with cirrhosis includes a range of medical, endoscopic and radiological interventions. This article updates the recent developments in this area and highlights topics where further research is still required.

Bleeding complications in critically ill patients with liver cirrhosis

BACKGROUND/AIMS

Patients with liver cirrhosis (LC) are at risk for critical events leading to Intensive Care Unit (ICU) admission. Coagulopathy in cirrhotic patients is complex and can lead to bleeding as well as thrombosis. The aim of this study was to investigate bleeding complications in critically ill patients with LC admitted to a medical ICU (MICU).

METHODS

All adult patients admitted to our MICU with a diagnosis of LC from January 2006 to December 2012 were retrospectively assessed. Patients with major bleeding at the time of MICU admission were excluded from the analysis.

RESULTS

A total of 205 patients were included in the analysis. The median patient age was 62 years, and 69.3% of the patients were male. The most common reason for MICU admission was acute respiratory failure (45.4%), followed by sepsis (27.3%). Major bleeding occurred in 25 patients (12.2%). The gastrointestinal tract was the most common site of bleeding (64%), followed by the respiratory tract (20%). In a multivariate analysis, a low platelet count at MICU admission (odds ratio [OR], 0.98; 95% confidence interval [CI], 0.97 to 0.99) and sepsis (OR, 8.35; 95% CI, 1.04 to 67.05) were independent risk factors for major bleeding. The ICU fatality rate was significantly greater among patients with major bleeding (84.0% vs. 58.9%, respectively; p = 0.015).

CONCLUSIONS

Major bleeding occurred in 12.2% of critically ill cirrhotic patients admitted to the MICU. A low platelet count at MICU admission and sepsis were associated with an increased risk of major bleeding during the MICU stay. Further study is needed to better understand hemostasis in critically ill patients with LC.

Liver stiffness plus platelet count can be used to exclude high-risk oesophageal varices

BACKGROUND/AIMS

Endoscopic screening for high-risk gastro-oesophageal varices (GOV) is recommended for compensated cirrhotic patients with transient elastography identifying increasing numbers of patients with cirrhosis without portal hypertension. Using liver stiffness measurement (LSM) ± platelet count, the aim was to develop a simple clinical rule to exclude the presence of high-risk GOV in patients with Child-Pugh A cirrhosis.

METHODS

A retrospective analysis of 71 patients with Child-Pugh A cirrhosis diagnosed by transient elastography (LSM >13.6 kPa) who underwent screening gastroscopy was conducted. A predictive model using LSM ± platelet count was assessed to exclude the presence of high-risk GOV (diameter >5 mm and/or the presence of high-risk stigmata) and validated using a second cohort of 200 patients from two independent centres.

RESULTS

High-risk GOV were present in 10 (15%) and 16 (8%) of the training and validation cohorts, respectively, which was associated with LSM and Pl count (P < 0.05). A combined model based on LSM and Pl count was more accurate for excluding the presence of high-risk GOV than either alone (training cohort AUROC: 0.87 [0.77-0.96] vs. 0.78 [0.65-0.92] for LSM and 0.71 [0.52-0.90] for platelets) with the combination of LSM ≤25 kPa and Pl ≥100 having a NPV of 100% in both the training and validation cohorts. A total of 107 (39%) patients meet this criterion.

CONCLUSION

The combination of LSM ≤25 kPa and Pl ≥100 can be used in clinical practice to exclude the presence of high-risk GOV in patients with Child-Pugh A cirrhosis.

Alcohol Abuse Increases Rebleeding Risk and Mortality in Patients with Non-variceal Upper Gastrointestinal Bleeding

BACKGROUND

No current data are available on rebleeding and mortality risk in patients who use alcohol excessively and are admitted for non-variceal upper gastrointestinal bleeding (NVUGIB). This information could help in planning interventions and follow-up protocols for these patients.

AIM

This study provides contemporary data on the long-term outcome after first-time NVUGIB in alcohol abusers (AAs) compared to non-abusers (NAs).

METHODS

Consecutive patients hospitalized for their first acute gastrointestinal bleeding from 2009 through 2011 were retrospectively recorded and categorized as AA or NA. Risk factors for one-year mortality and rebleeding were identified, and patients were further monitored for long-term mortality until 2015.

RESULTS

Alcohol abuse was identified in 19.7% of patients with NVUGIB (n = 518). The one-year rebleeding rate was 16.7% in AAs versus 9.1% in NAs (P = 0.027). Alcohol abuse was associated with a twofold increase in rebleeding risk (P = 0.025); the risk especially increased 6 months after the initial bleeding. The study groups did not differ significantly in 30-day (6.0%) or one-year mortality rates (20.5%). However, there was a tendency for higher overall mortality in AAs than NAs after adjustment of comorbidities.

CONCLUSION

AAs with NVUGIB are at high risk of rebleeding, and mortality is increased in AA patients. A close follow-up strategy and long-term proton pump inhibitor therapy are recommended for AA patients with peptic ulcer or esophagitis.

Predicting risk factors for rebleeding, infections, mortality following peptic ulcer bleeding in patients with cirrhosis and the impact of antibiotics prophylaxis at different clinical stages of the disease

Background

Infections in cirrhotic patients with upper gastrointestinal bleeding are a common event causing severe complication and mortality. This study aimed to identify risk factors that may predict rebleeding, bacterial infections, and the impact of antibiotic prophylaxis on mortality at different stages of cirrhosis following acute peptic ulcer bleeding (PUB).

Methods

A hospital-based retrospective cohort study was conducted on 235 cirrhotic patients with acute peptic ulcer hemorrhage who underwent therapeutic endoscopic procedures between January 2008 and January 2014 (n = 235); of these, 88 patients received prophylactic intravenous ceftriaxone (antibiotic group) and 147 patients did not (nil-antibiotic group). The recorded outcomes were length of hospital stay, bacterial infection, rebleeding, and in-hospital mortality.

Results

Forty-eight (20.4 %) patients experienced ulcer rebleeding and 46 (19.6 %) developed bacterial infections. More patients suffered from infection and recurrent bleeding in the nil-antibiotic group than the antibiotic group (25.2 % vs. 10.2 %, p = 0.005 and 30.6 % vs. 3.4 %; p < 0.001, respectively). The predictive risk factors for rebleeding were the Rockall score (p = 0.004), units of blood transfusion (p = 0.031), and no antibiotic prophylaxis (p <0.001); for bacterial infections, they were the Child-Pugh score (p = 0.003), active alcoholism (p = 0.035), and no antibiotic prophylaxis (p = 0.009). Overall, 40 (17 %) patients died during hospitalization. The Rockall score and rebleeding were predictive factors for in-hospital mortality. In subgroup analysis, survival was significantly reduced in decompensated patients (p = 0.034).

Conclusions

This study suggests that antibiotic prophylaxis after endoscopic hemostasis for acute PUB prevented infections and reduced rebleeding events in cirrhotic patients. Antibiotic prophylaxis improved survival among decompensated cohort following PUB. The Rockall score and rebleeding were predictive risk factors for in-hospital mortality.

Gastrointestinal dysfunction in liver cirrhosis

Patients with liver cirrhosis exhibit several features of gut dysfunction which may contribute to the development of cirrhosis complications as well as have an impact on nutritional status and health-related quality of life. Gastrointestinal symptoms are common in cirrhosis and their pathophysiology probably involves factors related to liver disease severity, psychological distress, and gut dysfunction (e.g., increased gastric sensitivity to distension and delayed gut transit). They may lead to reduced food intake and, thus, may contribute to the nutritional status deterioration in cirrhotic patients. Although tense ascites appears to have a negative impact on meal-induced accommodation of the stomach, published data on gastric accommodation in cirrhotics without significant ascites are not unanimous. Gastric emptying and small bowel transit have generally been shown to be prolonged. This may be related to disturbances in postprandial glucose, insulin, and ghrelin levels, which, in turn, appear to be associated to insulin resistance, a common finding in cirrhosis. Furthermore, small bowel manometry disturbances and delayed gut transit may be associated with the development of small bowel bacterial overgrowth. Finally, several studies have reported intestinal barrier dysfunction in patients with cirrhosis (especially those with portal hypertension), which is related to bacterial translocation and permeation of intestinal bacterial products, e.g., endotoxin and bacterial DNA, thus potentially being involved in the pathogenesis of complications of liver cirrhosis.

Peptic ulcer disease in liver cirrhosis and chronic hepatitis: impact of portal hypertension

OBJECTIVE

The pathophysiology of peptic ulcer disease (PUD) in liver cirrhosis (LC) and chronic hepatitis has not been established. The aim of this study was to assess the role of portal hypertension from PUD in patients with LC and chronic hepatitis.

MATERIALS AND METHODS

We analyzed the medical records of 455 hepatic vein pressure gradient (HVPG) and esophagogastroduodenoscopy patients who had LC or chronic hepatitis in a single tertiary hospital. The association of PUD with LC and chronic hepatitis was assessed by univariate and multivariate analysis.

RESULTS

A total of 72 PUD cases were detected. PUD was associated with LC more than with chronic hepatitis (odds ratio [OR]: 4.13, p = 0.03). In the univariate analysis, taking an ulcerogenic medication was associated with PUD in patients with LC (OR: 4.34, p = 0.04) and smoking was associated with PUD in patients with chronic hepatitis (OR: 3.61, p = 0.04). In the multivariate analysis, taking an ulcerogenic medication was associated with PUD in patients with LC (OR: 2.93, p = 0.04). However, HVPG was not related to PUD in patients with LC or chronic hepatitis.

CONCLUSION

According to the present study, patients with LC have a higher risk of PUD than those with chronic hepatitis. The risk factor was taking ulcerogenic medication. However, HVPG reflecting portal hypertension was not associated with PUD in LC or chronic hepatitis (Clinicaltrial number NCT01944878).

H. pylori eradication lower ulcers in cirrhosis. [Corrected]

OBIECTIVE

The study aimed to investigate whether early Helicobacter pylori (H. pylori) eradication therapy in cirrhotic patients caused a dramatic reduction of recurrent peptic ulcers compared with those treated with a late eradication.

METHODS

We identified cirrhotic patients using the International Classifications of Diseases, Revision 9 (ICD-9-CM). Decompensated cirrhotic patients can apply for a catastrophic illness card and were identified via the ICD-9-CM codes 571.2, 571.5 and 571.6. Compensated cirrhotic patients were identified via the ICD-9-CM codes 571.2, 571.5 and 571.6, after excluded decompensated cirrhotic patients. We categorized patients into early (time lag ≤365 days after peptic ulcer diagnosis) and late (time lag >365 days) H. pylori eradication therapy groups. The end-point was the occurrence of recurrent peptic ulcers. Cox proportional hazards model was used to calculate the hazard ratios (HRs).

RESULTS

Altogether, 154 cirrhotic patients were included in the early H. pylori eradication group and 103 in the late H. pylori eradication group. Cirrhotic patients had a higher risk of recurrent peptic ulcers in the late H. pylori eradication group (HR 1.58, 95% CI 1.09-2.28, P = 0.015). However, the risk of recurrent peptic ulcers in alcoholic cirrhotic patients in both groups (HR 1.47, 95% CI 0.77-2.83, P = 0.247) was similar.

CONCLUSIONS

Early H. pylori eradication is associated with a lower risk of recurrent peptic ulcers in cirrhotic patients. H. pylori eradication is the mainstay for treating cirrhotic patients who have contracted peptic ulcers.

Increased mortality with peptic ulcer bleeding in patients with both compensated and decompensated cirrhosis

BACKGROUND

Cirrhosis is associated with worse outcomes in peptic ulcer bleeding (PUB). There are no population-based studies from the United States on the impact of cirrhosis on PUB outcomes.

OBJECTIVE

To investigate the impact of cirrhosis on outcomes of patients with PUB.

DESIGN

Cross-sectional study.

SETTING

Nationwide Inpatient Sample 2009.

PATIENTS

International Classification of Diseases, the 9th revision, codes were used to identify patients with PUB and cirrhosis. The control group was patients with PUB without cirrhosis.

MAIN OUTCOME MEASUREMENTS

In-hospital mortality, length of stay, and hospitalization costs.

RESULTS

A total of 96,887 discharges with PUB as a diagnosis were identified-3574 with PUB and cirrhosis and 93,313 with PUB alone without cirrhosis. Mortality of PUB with concomitant cirrhosis was higher than in the control group without cirrhosis (5.5% vs 2%; P = .01); decompensated cirrhosis had higher mortality than did compensated cirrhosis (6.6% vs 3.9%; P = .01). In multivariate analysis, the presence of cirrhosis independently increased mortality (adjusted odds ratio (aOR) 3.3; 95% confidence interval [CI], 2.2-4.9). Stratified analysis showed that decompensated cirrhosis (aOR 4.4; 95% CI, 2.6-7.3) had higher mortality than compensated cirrhosis (aOR 1.9; 95% CI, 1.04-3.6). There was no difference in the proportion of patients who underwent endoscopy within 24 hours (51.9% vs 51.1%; P = .68) between those with cirrhosis and controls. Patients with cirrhosis received less surgical intervention (aOR 0.8; 95% CI, 0.6-0.9) compared with controls. Hospitalization costs also were increased in patients with decompensated cirrhosis.

LIMITATIONS

Administrative data set.

CONCLUSION

Both decompensated and compensated cirrhosis are associated with increased mortality in patients with PUB.

Cirrhotic patients at increased risk of peptic ulcer bleeding: a nationwide population-based cohort study

BACKGROUND

Few large population-based studies have compared the occurrence of peptic ulcer bleeding (PUB) in cirrhotic and noncirrhotic patients.

AIMS

To investigate if cirrhotic patients have higher risk of PUB than the general population and to identify possible risk factors of PUB in cirrhotic patients.

METHODS

Using the National Health Insurance Research Database, a nationwide population-based dataset in Taiwan and matching age, gender, comorbidities and ulcerogenic medication by propensity score, 4013 cirrhotic patients, 8013 chronic hepatitis patients and 7793 normal controls were compared. The log-rank test was used to analyse differences in accumulated PUB-free survival rates between the groups. Cox proportional hazard regressions were performed to evaluate independent risk factors for PUB in all patients and identified risk factors of PUB in cirrhotic patients.

RESULTS

During the 7-year follow-up, cirrhotic patients had significantly higher incidences of PUB than chronic hepatitis patients and controls, respectively (P < 0.001 by log-rank test). By Cox proportional hazard regression analysis, cirrhosis was independently associated with increased risk of PUB (hazard ratio: 4.22; 95% CI 3.37-5.29, P < 0.001) after adjusting for age, gender, economic status, underlying comorbidities and ulcerogenic medication. Age, male, diabetes, chronic renal disease, history of gastro-oesophageal variceal bleeding and use of nonsteroidal anti-inflammatory drugs were risk factors for PUB in cirrhotic patients.

CONCLUSION

Cirrhotic patients have a significantly higher risk of peptic ulcer bleeding after adjustments for possible confounding factors like age, gender, economic status, underlying comorbidities and ulcerogenic medication.
