Risk factors for rebleeding and death from peptic ulcer in the very elderly

Risk factors of poor prognosis and impairment of activities of daily living in patients with hemorrhagic gastroduodenal ulcers

Background

Impairment of activities of daily living (ADL) due to hemorrhagic gastroduodenal ulcers (HGU) has rarely been evaluated. We analyzed the risk factors of poor prognosis, including mortality and impairment of ADL, in patients with HGU.

Methods

In total, 582 patients diagnosed with HGU were retrospectively analyzed. Admission to a care facility or the need for home adaptations during hospitalization were defined as ADL decline. The clinical factors were evaluated: endoscopic features, need for interventional endoscopic procedures, comorbidities, symptoms, and medications. The risk factors of outcomes were examined with multivariate analysis.

Results

Advanced age (> 75 years) was a significant predictor of poor prognosis, including impairment of ADL. Additional significant risk factors were renal disease (odds ratio [OR] 3.43; 95% confidence interval [CI] 1.44–8.14) for overall mortality, proton pump inhibitor (PPIs) usage prior to hemorrhage (OR 5.80; 95% CI 2.08–16.2), and heart disease (OR 3.05; 95% CI 1.11–8.43) for the impairment of ADL. Analysis of elderly (> 75 years) subjects alone also revealed that use of PPIs prior to hemorrhage was a significant predictor for the impairment of ADL (OR 8.24; 95% CI 2.36–28.7).

Conclusion

In addition to advanced age, the presence of comorbidities was a risk of poor outcomes in patients with HGU. PPI use prior to hemorrhage was a significant risk factor for the impairment of ADL, both in overall HGU patients and in elderly patients alone. These findings suggest that the current strategy for PPI use needs reconsideration.

Need of Emergency Surgery in Elderly Patients with Upper Gastrointestinal Bleeding: Survival Analysis during 2009-2015

BACKGROUND/AIMS

The role of emergency surgery is decreasing in the treatment of patients with upper gastrointestinal bleeding (UGIB). We investigated the need of urgent surgery and outcome of elderly UGIB patients who often have cardiovascular comorbidities with antithrombotic medication.

METHODS

All consecutive adult patients who received emergency treatment for suspected gastrointestinal bleeding between January 2009 and December 2011 were registered in an electronic database (n = 1,643). A total of 569 patients with a first-time UGIB were identified, of whom 282 were ≥70 years old. Age-specific incidence rates, risk factors for bleeding and need of endoscopic or emergency surgery were studied. Long-term mortality was compared to age-adjusted control subjects (n = 569) without bleeding.

RESULTS

The age-specific incidence of UGIB increased from 156 to 401 cases per 100,000 inhabitants from age 60-69 to 80-89 years, respectively. Cardiovascular comorbidities and antithrombotic therapies (acetosalicylic acid 51 vs. 27%; warfarins 25 vs. 11%) related to UGIB were more common in patients over than under 70 years of age (p < 0.0001). Early endoscopic therapy was successful in over 95% of patients, whereas emergency surgery was needed only in 6 (2%) patients ≥70 years old. Hospital mortality (7.8%) was acceptable in these patients, but the 5-year mortality (40%) was significantly higher than in controls (20%, p < 0.001).

CONCLUSION

Today, emergency surgery is seldom needed in the patients with UGIB. In comparison to the age-matched control population, long-term survival was significantly lower after UGIB in the elderly.

Characteristics and outcomes of gastroduodenal ulcer bleeding: a single-centre experience in Lithuania

Introduction

Despite the optimal use of combined endoscopic haemostasis and pharmacologic control of acid secretion in the stomach, mortality in patients with peptic ulcer bleeding (PUB) has remained constant. Recent data has shown that the majority of patients with PUB die of non-bleeding-related causes.

Aim

To provide an overview of our experience of PUB management, with emphasis on the effect of age, gender, comorbidities, and drug use on the characteristics and outcomes of gastroduodenal ulcer bleeding.

Material and methods

We retrospectively reviewed the medical records of all patients admitted with the primary diagnosis of acute, chronic or unspecified gastric and/or duodenal ulcer with haemorrhage during 2008–2012.

Results

Two hundred and nineteen patients were identified. 46.6% of patients were ≥ 65 years old (elderly) and 53.4% were < 65 years old (young). The young patients were more likely to have duodenal ulcers and liver failure at admission. Previous use of medications was more regularly observed in gastric ulcer patients than in duodenal ulcer patients. Rebleeding occurred in 43 (19.6%) patients and death in 5 (2.3%) patients. Increased risk of mortality in our patients was associated with age ≥ 65 years (RR = 2.21; 95% CI: 1.90–2.56; p = 0.021).

Conclusions

Management of peptic ulcer bleeding should aim at reducing the risk of multiorgan failure and cardiopulmonary death instead of focusing merely on successful haemostasis.

Use of proton pump inhibitors and mortality after hip fracture in a nationwide study

We analyzed the association of proton pump inhibitors (PPIs) with mortality after osteoporosis-related hip fracture in Austria. PPIs were associated with reduced 90-day mortality but elevated mortality after half a year when initiated pre-fracture. Inpatients and discharged patients on PPIs showed lowered in-hospital and 90-day mortality, respectively.

INTRODUCTION

We herein investigated use of proton pump inhibitors (PPIs) and mortality among hip fracture patients in a nationwide study in Austria.

METHODS

In this retrospective cohort study, data on use of PPIs were obtained from 31,668 Austrian patients ≥50 years with a hip fracture between July 2008 and December 2010. All-cause mortality in patients without anti-osteoporotic drug treatment who had received their first recorded PPI prescription in the study period either before or after fracture was compared with hip fracture patients on neither PPIs nor anti-osteoporotic medication using logistic and Cox regression analysis.

RESULTS

With PPI use, 90-day mortality was significantly reduced, both at initiation before (OR 0.66; p < 0.0001) and after hip fracture (OR 0.23; p < 0.0001). 90-day mortality was also reduced when PPIs were prescribed not until after discharge from the last recorded hip fracture-related hospital stay (OR 0.49; p < 0.0001) except for patients aged <70 years. In a sub-cohort of patients beginning PPIs during hospital stay, in-hospital mortality (0.2%) was substantially reduced relative to matched control patients (3.5%) (p < 0.0001). Longer-term mortality significantly increased after half a year post-fracture only among those who started PPI prescription before fracture.

CONCLUSIONS

PPI use during and after hospital stay due to hip fracture is associated with a considerable decrease in mortality. These findings could have implications for hip fracture treatment.

Nonvariceal upper gastrointestinal bleeding in elderly people: Clinical outcomes and prognostic factors

OBJECTIVE

To analyze the clinical characteristics, outcomes and prognostic factors in elderly patients (aged 75 years and elder) with acute nonvariceal upper gastrointestinal bleeding (UGIB).

METHODS

Consecutive patients admitted with acute nonvariceal UGIB who underwent upper gastrointestinal endoscopy were prospectively recruited and subdivided into two age-based groups, elderly (aged ≥75 years) and younger patients (<75 years). The patients' characteristics and outcomes were recorded.

RESULTS

Altogether 1136 patients were included in the study, 276 (24.3%) aged ≥75 years. Peptic ulcers, gastroduodenal erosions and esophagitis represented the three most common endoscopic lesions found in 87.7% of the elderly patients compared with 80.8% in younger patients ( P  = 0.008). Overall, the rebleeding rate (4.0% vs 3.3%, P = 0.568), need for blood transfusion (66.3% vs 61.0%, P = 0.122), surgery rate (1.2% vs 1.4%, P = 0.947) and in-hospital mortality (13.0% vs 10.0%, P = 0.157) were not different between the two groups. In elderly patients, serum albumin was the only predictive variable independently associated with mortality in the overall analysis (OR 5.867, 95% CI 2.206-15.604, P < 0.001) and in the subgroup patients with peptic ulcers (OR 5.230, 95% CI 2.099-13.029, P = 0.001). Elderly patients with serum albumin >23.5 g/L at admission presented a low mortality (negative predictive value 97.3%).

CONCLUSIONS

Clinical evolution and mortality do not differ between the elderly and younger patients with acute nonvariceal UGIB. Serum albumin level at admission is a prognostic marker for mortality in elder patients.

Factors predicting mortality of elderly patients with acute upper gastrointestinal bleeding

Background

Acute upper gastrointestinal bleeding (UGIB) is a common gastrointestinal disease emergency and a cause of morbidity and mortality.

Objectives

To assess the clinical outcomes and explore predictive factors for mortality of elderly patients with acute UGIB.

Methods

During the study period from January 2010 to September 2011, we prospectively enrolled 981 patients presenting with UGIB from 11 hospitals (mean age ± standard deviation (SD), 59.4 ± 14.9 years; range, 17–94 years; including 661 men). Of these 981 patients, 499 (50.9%) were elderly. Basic demographic data and clinical findings, and Rockall scores were collected and calculated.

Results

We studied 499 elderly patients. Their mean age ± SD was 71.63 ± 7.65 years. The 30-day mortality rate was 9% and rebleeding was just 1%. Regression analysis showed a pulse rate >100 beats per min at first visit, red blood in a nasogastric aspiration, comorbidity with coronary artery disease, and creatinine >1.5 mg/dL were independent predictive factors of 30-day mortality.

Conclusions

Peptic ulcer bleeding is a major cause of acute UGBI in the elderly. We recommend patients with predictive factors of mortality, pulse rate >100 beats per min at first visit, red blood in nasogastric aspiration, comorbidity with coronary artery disease, and creatinine >1.5 mg/dL be closely monitored and treated promptly. Reducing mortality from peptic ulcer bleeding should focus on preventing peptic ulcer occurrence as a result of ulcerogenic medications.

Independent risk factors of 30-day outcomes in 1264 patients with peptic ulcer bleeding in the USA: large ulcers do worse

BACKGROUND

Predictors of worse outcomes (rebleeding, surgery and death) of peptic ulcer bleeds (PUBs) are essential indicators because of significant morbidity and mortality rates of PUBs. However those have been infrequently reported since changes in medical therapy (PPI, proton pump inhibitors) and application of newer endoscopic haemostatic technique.

AIMS

To determine: (i) independent risk factors for 30-day rebleeding, surgery, and death and (ii) whether ulcer size is an independent predictor of major outcomes in patients with severe PUB after successful endoscopic haemostasis and treatment with optimal medical (high dose IV PPI) vs. prior treatment (high dose IV histamine 2 antagonists - H2RAs).

METHODS

A large prospectively followed population of patients hospitalised with severe PUBs between 1993 and 2011 at two US tertiary care academic medical centres, stratified by stigmata of recent haemorrhage (SRH) was studied. Using multivariable logistic regression analyses, independent risk factors for each outcome (rebleeding, surgery and death) up to 30 days were analysed. Effects for medical treatment (H2RA patients 1993-2005 vs. PPIs 2006-2011) were also analysed.

RESULTS

A total of 1264 patients were included. For ulcers ≥10 mm, the odds of 30-day rebleeding increased 6% per each 10% increase in ulcer size (OR 1.06, 95% CI 1.02-1.10, P = 0.0053). Other risk factors for 30-day rebleeding were major SRH, in-patient start of bleeding, and prior GI bleeding. Major SRH and ulcer size≥10 mm were predictors of 30-day surgery. Risk factors for 30-day death were major SRH, in-patient bleeding, and any initial platelet transfusion or fresh frozen plasma transfusion ≥2 units. Among patients with major SRH and out-patient start of bleeding, larger ulcer size was also a risk factor for death (OR 1.08 per 10% increase in ulcer size, 95% CI 1.02-1.14, P = 0.0095). Ulcer size was a significant independent variable for both time periods.

CONCLUSIONS

Ulcer size is a risk factor for worse outcomes after PUB and should be carefully recorded at initial endoscopy to improve patient triage and management.

Effect of dementia on outcomes of elderly patients with hemorrhagic peptic ulcer disease based on a national administrative database

BACKGROUND

Little information is available on the effect of dementia on outcomes of elderly patients with hemorrhagic peptic ulcer disease at the population level.

AIMS

This study aimed to investigate the effect of dementia on outcomes of elderly patients with hemorrhagic peptic ulcer based on a national administrative database.

METHODS

A total of 14,569 elderly patients (≥80 years) who were treated by endoscopic hemostasis for hemorrhagic peptic ulcer were referred to 1073 hospitals between 2010 and 2012 in Japan. We collected patients' data from the administrative database to compare clinical and medical economic outcomes of elderly patients with hemorrhagic peptic ulcers. Patients were divided into two groups according to the presence of dementia: patients with dementia (n = 695) and those without dementia (n = 13,874).

RESULTS

There were no significant differences in in-hospital mortality within 30 days and overall mortality between the groups (odds ratio; OR 1.00, 95 % confidence interval; CI 0.68-1.46, p = 0.986 and OR 1.02, 95 % CI 0.74-1.41, p = 0.877). However, the length of stay (LOS) and medical costs during hospitalization were significantly higher in patients with dementia compared with those without dementia. The unstandardized coefficient for LOS was 3.12 days (95 % CI 1.58-4.67 days, p < 0.001), whereas that for medical costs was 1171.7 US dollars (95 % CI 533.8-1809.5 US dollars, p < 0.001).

CONCLUSIONS

Length of stay and medical costs during hospitalization are significantly increased in elderly patients with dementia undergoing endoscopic hemostasis for hemorrhagic peptic ulcer disease.

Effect of comorbidity on mortality in patients with peptic ulcer bleeding: systematic review and meta-analysis

OBJECTIVES

By systematic review and meta-analysis, we sought to assess the impact of comorbidity on short-term mortality in patients with peptic ulcer bleeding (PUB).

METHODS

We conducted systematic searches in PubMed and Embase (January 1989-January 2010). Relative risks (RRs) were pooled across selected studies and an analysis of diagnostic test accuracy was performed to validate the results further.

RESULTS

Of 1,572 identified studies, 16 were eligible for inclusion. Only three had a low risk of bias and the overall quality of evidence was low. The risk of death (30-day or in-hospital mortality) was significantly greater in PUB patients with comorbidity than in those without (RR: 4.44; 95% confidence interval (CI): 2.45-8.04). The pooled sensitivity for comorbidity predicting death in patients with PUB was 0.86 (95% CI: 0.66-0.95) and the pooled specificity was 0.53 (95% CI: 0.40-0.65). PUB patients with three or more comorbidities had a greater risk of dying than those with one or two (RR: 3.46; 95% CI: 1.34-8.89). All individual comorbidities that we assessed significantly increased the risk of death associated with PUB. However, RRs were higher for hepatic, renal, and malignant disease (range: 4.04-6.33; no significant heterogeneity) than for cardiovascular and respiratory disease and diabetes (2.39, 2.45, and 1.63, respectively; no significant heterogeneity).

CONCLUSIONS

Underlying comorbidity is consistently associated with increased mortality in patients with PUB. The number and type of comorbidities in patients with PUB should be carefully evaluated and factored into initial management strategies.

The influence of diabetes mellitus on short-term outcomes of patients with bleeding peptic ulcers

PURPOSE

Little information is available on the influence of diabetes mellitus on the short-term clinical outcomes of patients with bleeding peptic ulcers. The aim of this study is to investigate whether diabetes mellitus influences the short-term clinical outcomes of patients with bleeding peptic ulcers using a Japanese national administrative database.

MATERIALS AND METHODS

A total of 4863 patients treated by endoscopic hemostasis on admission for bleeding peptic ulcers were referred to 586 participating hospitals in Japan. We collected their data to compare the risk-adjusted length of stay (LOS) and in-hospital mortality of patients with and without diabetes mellitus within 30 days. Patients were divided into two groups: patients with diabetes mellitus (n=434) and patients without diabetes mellitus (n=4429).

RESULTS

Mean LOS in patients with diabetes mellitus was significantly longer than those without diabetes mellitus (15.8 days vs. 12.5 days, p<0.001). Also, higher in-hospital mortality within 30 days was observed in patients with diabetes mellitus compared with those without diabetes mellitus (2.7% vs. 1.1%, p=0.004). Multiple linear regression analysis revealed that diabetes mellitus was significantly associated with an increase in risk-adjusted LOS. The standardized coefficient was 0.036 days (p=0.01). Furthermore, the analysis revealed that diabetes mellitus significantly increased the risk of in-hospital mortality within 30 days (odds ratio=2.285, 95% CI=1.161-4.497, p=0.017).

CONCLUSION

This study demonstrated that presence of diabetes mellitus significantly influences the short-term clinical outcomes of patients with bleeding peptic ulcers.

[Upper gastrointestinal haemorrhage in patients over 80 years-old]

OBJECTIVES

To evaluate the patient characteristics, outcome, and prognosis of upper gastrointestinal haemorrhage in the elderly.

MATERIAL AND METHODS

A prospective study was conducted on 103 patients aged 80 years and over, admitted to a Gastrointestinal Bleeding Unit after an episode of upper gastrointestinal bleeding. We analysed the personal history, the characteristics of the bleeding event, and whether an urgent diagnostic or therapeutic endoscopy was performed, in order to identify clinical data and endoscopic findings that may have an influence on the outcome of the haemorrhage.

RESULTS

The major cause of the haemorrhage was peptic ulcer in 65.1%, and 60.2% of patients were on chronic treatment with non-steroidal anti-inflammatory drugs. An urgent diagnostic endoscopy was performed in all of them, identifying the source of bleeding in 94.2%, and treatment was carried out on 28.2%. The likelihood of rebleeding was 8%, and 4.9% of patients underwent emergency surgery, with an overall mortality rate of 5.8%.

CONCLUSIONS

The performance of urgent endoscopy and the application of endoscopic haemostasis are safe and effective in stopping upper gastrointestinal bleeding in the elderly. This has significantly reduced the need for emergency surgery, improving the survival of the bleeding elderly patient and preventing recurrent bleeding.

Meta-analysis: predictors of rebleeding after endoscopic treatment for bleeding peptic ulcer

BACKGROUND

Determining the risk of rebleeding after endoscopic therapy for peptic ulcer bleeding (PUB) may be useful for establishing additional haemostatic measures in very high-risk patients.

AIM

To identify predictors of rebleeding after endoscopic therapy.

METHODS

Bibliographic database searches were performed to identify studies assessing rebleeding after endoscopic therapy for PUB. All searches and data abstraction were performed in duplicate. A parameter was considered to be an independent predictor of rebleeding when it was detected as prognostic by multivariate analyses in ≥2 studies. Pooled odds ratios (pOR) were calculated for prognostic variables.

RESULTS

Fourteen studies met the prespecified inclusion criteria. Pre-endoscopic predictors of rebleeding were: (i) Haemodynamic instability: significant in 9 of 13 studies evaluating the variable (pOR: 3.30, 95% CI: 2.57-4.24); (ii) Haemoglobin value: significant in 2 of 10 (pOR: 1.73, 95% CI: 1.14-2.62) and (iii) Transfusion: significant in two of six (pOR not calculable). Endoscopic predictors of rebleeding were: (i) Active bleeding: significant in 6 of 12 studies (pOR: 1.70, 95% CI: 1.31-2.22); (ii) Large ulcer size: significant in 8 of 12 studies (pOR: 2.81, 95% CI: 1.98-4.00); (iii) Posterior duodenal ulcer location: significant in four of eight studies (pOR: 3.83, 95% CI: 1.38-10.66) and (iv) High lesser gastric curvature ulcer location: significant in three of eight studies (pOR: 2.86; 95% CI: 1.69-4.86).

CONCLUSIONS

Major predictors for rebleeding in patients receiving endoscopic therapy are haemodynamic instability, active bleeding at endoscopy, large ulcer size, ulcer location, haemoglobin value and the need for transfusion. These risk factors may be useful for guiding clinical management in patients with PUB.

Characteristics and outcomes of acute upper gastrointestinal bleeding after therapeutic endoscopy in the elderly

AIM: To characterize the effects of age on clinical presentations and endoscopic diagnoses and to determine outcomes after endoscopic therapy among patients aged ≥ 65 years admitted for acute upper gastrointestinal bleeding (UGIB) compared with those aged < 65 years.

METHODS: Medical records and an endoscopy data-base of 526 consecutive patients with overt UGIB ad-mitted during 2007-2009 were reviewed. The initial presentations and clinical course within 30 d after endoscopy were obtained.

RESULTS: A total of 235 patients aged ≥ 65 years constituted the elderly population (mean age of 74.2 ± 6.7 years, 63% male). Compared to young patients, the elderly patients were more likely to present with melena (53% vs 30%, respectively; P < 0.001), have comorbidities (69% vs 54%, respectively; P < 0.001), and receive antiplatelet agents (39% vs 10%, respectively; P < 0.001). Interestingly, hemodynamic instability was observed less in this group (49% vs 68%, respectively; P < 0.001). Peptic ulcer was the leading cause of UGIB in the elderly patients, followed by varices and gastropathy. The elderly and young patients had a similar clinical course with regard to the utilization of endoscopic therapy, requirement for transfusion, duration of hospital stay, need for surgery [relative risk (RR), 0.31; 95% confidence interval (CI), 0.03-2.75; P = 0.26], rebleeding (RR, 1.44; 95% CI, 0.92-2.25; P = 0.11), and mortality (RR, 1.10; 95% CI, 0.57-2.11; P = 0.77). In Cox’s regression analysis, hemodynamic instability at presentation, background of liver cirrhosis or disseminated malignancy, transfusion requirement, and development of rebleeding were significantly associated with 30-d mortality.

CONCLUSION: Despite multiple comorbidities and the concomitant use of antiplatelets in the elderly patients, advanced age does not appear to influence adverse outcomes of acute UGIB after therapeutic endoscopy.

Equivalent clinical outcomes of bleeding peptic ulcers in teaching and non-teaching hospitals: evidence for standardization of medical care in Japan

The clinical outcomes of treatments for several medical conditions are better in teaching hospitals than in non-teaching hospitals. However, there is only limited information for comparisons of the clinical outcomes of bleeding peptic ulcers between teaching and non-teaching hospitals. A total of 4,863 patients treated by endoscopic hemostasis on admission for bleeding peptic ulcers were evaluated in 586 hospitals of the Diagnosis Procedure Combination (DPC) system. We collected their data from the database associated with the DPC system to compare the risk-adjusted length of stay (LOS) and in-hospital mortality within 30 days with respect to the hospital characteristics. The hospitals were categorized into two groups: teaching hospitals that were certified by the Japanese Society of Gastroenterology (3,332 patients in 360 hospitals) and non-teaching hospitals (1,531 patients in 226 hospitals). There was no significant difference with regard to the mean LOS and the crude in-hospital mortality within 30 days between groups (p = 0.181 and 0.174, respectively). Multiple linear regression analyses revealed that the hospital characteristics were not associated with the risk-adjusted LOS. The standardized coefficient for non-teaching hospitals was 0.019 (p = 0.172). Multiple logistic regression analyses further showed no significant difference in the in-hospital mortality within 30 days (non-teaching hospitals, odds ratio = 1.35, 95% confidence interval = 0.786 - 2.319, p = 0.277). In conclusion, both teaching and non-teaching hospitals have equivalent qualities in management of bleeding peptic ulcers. These findings suggest that the standardization of medical treatments for bleeding peptic ulcers has become disseminated in Japan.

Prognostic factors in gastrointestinal bleeding due to peptic ulcer: construction of a predictive model

OBJECTIVES

The identification of prognostic factors of easy application in clinical practice can improve the diagnostic and therapeutic decision making process in upper gastrointestinal bleeding (UGB). The present study estimates the capacity to predict an unfavorable clinical course (mortality, unstable bleeding, and/or interventional therapy) on the basis of the preendoscopic and endoscopic clinical analytical findings in patients with UGB owing to peptic ulcer.

METHOD

A retrospective cohort study was made of 473 adult patients seen in the Emergency Service of a District Hospital, and diagnosed with UGB secondary to gastroduodenal ulcer. Logistic regression analysis was used to construct different models, with the evaluation of their predictive capacity based on calculation of the area under the receiver operating curve (ROC). The final model was used to calculate the probabilities of an unfavorable clinical course for different profiles, with the purpose of constructing an algorithm of help in the decision making process applied to patients initially considered to be at low risk (Forrest classification IIb and III).

RESULTS

The model with the Forrest variable showed a high predictive capacity: ROCa=0.81 (95% confidence interval, 0.76-0.85). Incorporation to the model of clinical and preendoscopic factors (type of UGB, hematocrit, kidney failure, and liver disease) significantly increased its predictive capacity: ROCa=0.87 (95% confidence interval, 0.83-0.91). This model allows the differentiation of different complication risk levels in patients initially at low risk according to the Forrest classification (IIb and III).

CONCLUSIONS

The Forrest classification is the principal predictive factor for an unfavorable course in patients with gastrointestinal bleeding owing to peptic ulcer, though clinical factors are also important and should complement the decision taking process.

Acute upper gastrointestinal bleeding in octogenarians: Clinical outcome and factors related to mortality

AIM: To evaluate the aetiology, clinical outcome and factors related to mortality of acute upper gastrointestinal bleeding (AUGIB) in octogenarians.

METHODS: We reviewed the records of all patients over 65 years old who were hospitalised with AUGIB in two hospitals from January 2006 to December of 2006. Patients were divided into two groups: Group A (65-80 years old) and Group B (> 80 years old).

RESULTS: Four hundred and sixteen patients over 65 years of age were hospitalized because of AUGIB. Group A included 269 patients and Group B 147 patients. Co-morbidity was more common in octogenarians (P = 0.04). The main cause of bleeding was peptic ulcer in both groups. Rebleeding and emergency surgery were uncommon in octogenarians and not different from those in younger patients. In-hospital complications were more common in octogenarians (P = 0.05) and more patients died in the group of octogenarians compared to the younger age group (P = 0.02). Inability to perform endoscopic examination (P = 0.002), presence of high risk for rebleeding stigmata (P = 0.004), urea on admission (P = 0.036), rebleeding (P = 0.004) and presence of severe co-morbidity (P < 0.0001) were related to mortality. In multivariate analysis, only the presence of severe co-morbidity was independently related to mortality (P = 0.032).

CONCLUSION: While rebleeding and emergency surgery rates are relatively low in octogenarians with AUGIB, the presence of severe co-morbidity is the main factor of adverse outcome.

Gastrointestinal bleeding in the elderly

Gastrointestinal bleeding affects a substantial number of elderly people and is a frequent indication for hospitalization. Bleeding can originate from either the upper or lower gastrointestinal tract, and patients with gastrointestinal bleeding present with a range of symptoms. In the elderly, the nature, severity, and outcome of bleeding are influenced by the presence of medical comorbidities and the use of antiplatelet medication. This Review discusses trends in the epidemiology and outcome of gastrointestinal bleeding in elderly patients. Specific causes of upper and lower gastrointestinal bleeding are discussed, and recommendations for approaches to endoscopic diagnosis and therapy are given.

Current management of Helicobacter pylori infections in the elderly

Helicobacter pylori infection is a chronic gastric gram-negative infection that increases with age worldwide. However, the percentage age of H. pylori-positive elderly patients who are tested and treated for their infection remains very low. It is now demonstrated that H. pylori infection induces a whole cascade of events leading to gastric pathologies, such as peptic ulcer diseases, gastric precancerous lesions and gastric cancer. Recent data also demonstrated that H. pylori chronic infection can play a role in gastric aging, appetite regulation and extradigestive diseases, such as Alzheimer's disease, in the elderly. The diagnosis of H. pylori infection remains difficult to realize in the very old population, and the urea breath test obtains the best performance in this population. 1-week proton pump inhibitor-based triple therapy regimens are highly effective and well tolerated in elderly patients, and antibiotic resistance remains very low. Low compliance is the main factor related to treatment failure in this population.

Infection à Helicobacter pylori chez la personne âgée

PURPOSES

Helicobacter pylori (H. pylori) infection is a chronic gastric Gram-negative infection that increases with age. Acquired in childhood, H. pylori infection may induce a whole cascade of events leading to gastric pathologies such as peptic ulcer diseases, gastric precancerous lesions, and gastric lymphomas (MALT). The characteristics of the diagnosis and the treatment of this infection in geriatrics are thus particularly important to take into account.

MAIN POINTS

1) The incidence of gastric and duodenal ulcers and their bleeding complications is increasing in old-aged populations. Clinical signs such as anorexia and malnutrition are proven to be excellent indications for endoscopic explorations in the elderly. NSAID-use and H. pylori infection were shown to be independent and unrelated risk factors for peptic ulcer and gastroduodenal bleeding in elderly subjects; 2) H. pylori infection diagnosis is difficult to realize in the very old population, and the urea breath test is the test which obtain the best performances in this population.

PERSPECTIVES

Recent work showed the part played by H. pylori chronic infection in gastric aging and in appetite regulation in the elderly. Research tasks should be continued in this field in order to better understand the part played by this chronic infection in gastric aging and in other pathologies (i.e. neurological or cardiovascular diseases) in this population.

The vital threat of an upper gastrointestinal bleeding: Risk factor analysis of 121 consecutive patients

AIM: To analyze the importance in predicting patients risk of mortality due to upper gastrointestinal (UGI) bleeding under today's therapeutic regimen.

METHODS: From 1998 to 2001, 121 patients with the diagnosis of UGI bleeding were treated in our hospital. Based on the patients’ data, a retrospective multivariate data analysis with initially more than 270 single factors was performed. Subsequently, the following potential risk factors underwent a logistic regression analysis: age, gender, initial hemoglobin, coumarines, liver cirrhosis, prothrombin time (PT), gastric ulcer (small curvature), duodenal ulcer (bulbus back wall), Forrest classification, vascular stump, variceal bleeding, Mallory-Weiss syndrome, RBC substitution, recurrent bleeding, conservative and surgical therapy.

RESULTS: Seventy male (58%) and 51 female (42%) patients with a median age of 70 (range: 21-96) years were treated. Their in-hospital mortality was 14%. While 12% (11/91) of the patients died after conservative therapy, 20% (6/30) died after undergoing surgical therapy. UGI bleeding occurred due to duodenal ulcer (n = 36; 30%), gastric ulcer (n = 35; 29%), esophageal varicosis (n = 12; 10%), Mallory-Weiss syndrome (n = 8; 7%), erosive lesions of the mucosa (n = 20; 17%), cancer (n = 5; 4%), coagulopathy (n = 4; 3%), lymphoma (n = 2; 2%), benign tumor (n = 2; 2%) and unknown reason (n = 1; 1%). A logistic regression analysis of all aforementioned factors revealed that liver cirrhosis and duodenal ulcer (bulbus back wall) were associated risk factors for a fatal course after UGI bleeding. Prior to endoscopy, only liver cirrhosis was an assessable risk factor. Thereafter, liver cirrhosis, the location of a bleeding ulcer (bulbus back wall) and patients’ gender (male) were of prognostic importance for the clinical outcome (mortality) of patients with a bleeding ulcer.

CONCLUSION: Most prognostic parameters used in clinical routine today are not reliable enough in predicting a patient’s vital threat posed by an UGI bleeding. Liver cirrhosis, on the other hand, is significantly more frequently associated with an increased risk to die after bleeding of an ulcer located at the posterior duodenal wall.

Neue Epidemiologie der akuten gastrointestinalen Blutung

Due to progress in general medicine and especially in gastroenterology, the incidence of acute gastrointestinal hemorrhage could be expected to have decreased during the last 25 years. However, published epidemiological data cannot, in general, fulfill this hope. The interpretation of potential trends is, however, often limited by low study quality. For example, questionable bleeding sources such as erosions in the upper gastrointestinal tract or colon diverticula are often rather uncritically named the definitive causes of bleeding. However, there is clear evidence of changes in grouping of patients. After the almost complete disappearance of Helicobacter pylori in younger indigenous populations of most industrialized countries, it is mostly elderly comorbid people with additional risk factors (NSAID use, low-dose aspirin, anticoagulation) who are affected. Not unexpectedly, this group has generally experienced no change in incidence and in fact shows a deterioration of prognosis in case of acute bleeding.

Comparative Analysis of Vagotomy and Drainage Versus Vagotomy and Resection Procedures for Bleeding Peptic Ulcer Disease: Results of 907 Patients from the Department of Veterans Affairs National Surgical Quality Improvement Program Database

BACKGROUND

The purpose of this study was to determine postoperative outcomes and risk factors for morbidity and mortality in patients requiring surgery for bleeding peptic ulcer disease (PUD). Vagotomy and drainage procedures are technically simpler but are usually associated with higher ulcer recurrence rates. In contrast, vagotomy and resection approaches offer lower ulcer recurrences but represent much more challenging operations and are associated with considerable morbidity and mortality.

STUDY DESIGN

Data collected through the Department of Veterans Affairs National Surgical Quality Improvement Program database from 1991 to 2001 were submitted for stepwise logistic regression analysis for prediction of 30-day postoperative morbidity and mortality, rebleeding, and postoperative length of stay. The study population included all patients operated on for bleeding PUD within an 11-year period.

RESULTS

The 30-day morbidity, mortality, and rebleeding rates were comparable between surgical groups. Age, American Society of Anesthesiologists class, presence of ascites, coma, diabetes, functional status, hemiplegia, and history of steroid use were predictors of postoperative death. Risk factors for rebleeding included dependent functional status, history of congestive heart failure, smoking, steroid use, and preoperative transfusions. Having a resective procedure, American Society of Anesthesiologists class, hemiplegia, history of COPD, and requiring ventilator-assisted respirations before surgery were positively associated with increased length of hospital stay.

CONCLUSIONS

No differences were observed in 30-day mortality, morbidity, or rebleeding rates between surgical groups. Having a resective procedure was a predictor of prolonged postoperative stay. Dependent status and chronic use of steroids were predictors of both rebleeding and postoperative mortality.

Time-trends in the epidemiology of peptic ulcer bleeding

OBJECTIVE

Despite the introduction of effective medical treatment of peptic ulcer disease, bleeding is still a frequent complication. The aim of this study was to investigate whether the incidence and the risk profile of peptic ulcer haemorrhage have changed within a 10-year period.

MATERIAL AND METHODS

In a prospective epidemiological and observational study the incidence and risk profile of peptic ulcer haemorrhage in Düsseldorf, Germany were compared between two time periods (period A: 1.3.89-28.2.90 and period B: 1.4.99-31.3.2000), involving nine hospitals with both surgical and medical departments. Patients with proven peptic ulcer haemorrhage at endoscopy or operation were included in the study; those with bleeding under defined severe stress conditions were excluded.

RESULTS

No differences in bleeding ulcer incidence were observed between periods A and B (51.4 per 100,000 person-years versus 48.7), or for duodenal ulcer (24.9 versus 25.7) or for gastric ulcer bleeding (26.5 versus 23.0). A marked increase in incidence rates was observed with increasing age. In period B, patients with bleeding ulcers were older (56% versus 41% 70 years or older), were usually taking non-steroidal anti-inflammatory drugs (NSAIDs) (45% versus 27%) and were less likely to have a history of ulcer (25% versus 59%) compared with patients in period A.

CONCLUSIONS

The persisting high incidence of peptic ulcer disease is a superimposing of two trends: a higher incidence in the growing population of elderly patient with a higher intake of NSAIDs and a lower incidence among younger patients due to a decrease in incidence and improved medical treatment.

Endoscopic hemostasis: safe treatment for peptic ulcer patients aged 80 years or older?

BACKGROUND AND AIM

Recently, the number of peptic ulcer patients aged 80 years or older has been increasing. However, little information is available concerning therapeutic endoscopy for these patients. The objective of this study was to evaluate the efficacy of endoscopic hemostasis for peptic ulcer bleeding in patients aged 80 years or older.

METHODS

In this 7-year study, bleeding peptic ulcer patients were divided into group A (>/=80 years old) and group B (<80 years), for which prospective data, endoscopic findings and outcomes of endoscopic treatment were compared.

RESULTS

Of the 459 patients who underwent endoscopic hemostasis for peptic ulcer bleeding, the 42 patients (average age 84 +/- 3 years) in group A had a significantly higher incidence of concomitant disease, lower hemoglobin, transfusional requirement over 800 mL and lower serum albumin than the 417 patients (average age 55 +/- 13 years) in group B. Significantly more patients in group A had large gastric ulcers. More patients in group A had ulcers located at the proximal third of the stomach, which is technically difficult to treat endoscopically. Nevertheless, all patients in groups A and B underwent initial hemostasis successfully. The rebleeding rate was not significantly different between group A and B. Neither group had hospital deaths nor complications related to endoscopic procedures.

CONCLUSIONS

Endoscopic hemostasis for peptic ulcer bleeding in patients aged 80 years or older is effective and safe. Increasing age may no longer be a risk factor for rebleeding and hospital death after endoscopic hemostasis for peptic ulcer bleeding.

Physiology and organ-related pathology of the elderly: stomach ulcers

Peptic ulcer disease, particularly as a result of its complications, is a burden that is focused on the elderly through their higher Helicobacter pylori prevalence and use of non-steroidal anti-inflammatory drugs (NSAIDs). In these patients, senescence may further increase ulcer susceptibility, particularly in the stomach, by the loss of mucosal protection and repair mechanisms. Age is mainly a marker for the increased prevalence of other complicated ulcer risk factors such as previous ulcer history and use of anti-coagulants, steroids and aspirin. The development of selective cyclo-oxygenase inhibitors (coxibs) has reduced the specific risk of NSAID ulceration, but the residual incidence in high risk patients remains substantially higher than that in young patients without other risk factors. The argument for early surgery versus endoscopic therapy in high risk patients with bleeding ulcers has not been resolved, both having a high mortality. There is still potential for the development of new strategies to prevent primary and secondary ulcers, either by new drug development or by expanding existing co-prescription strategies.

Gastrointestinal bleeding in the elderly

Gastrointestinal bleeding in elderly individuals is a frequent cause of consultation with a physician and of hospital admissions. Co-morbidity and greater medication use in this steadily growing patient group influence the clinical course and adversely affect outcome. Clinical presentation is often predictable and guides subsequent patient management. Due to a surprising lack of prospective controlled data in the area of gastrointestinal bleeding, the selection of diagnostic and therapeutic manoeuvres often depends more on local expertise and availability than on an algorithmic approach. Advances in endoscopic, medical, radiological and surgical treatment modalities offer promising new diagnostic and therapeutic tools, particularly in concerted applications. Outcome studies on the appropriate sequence and linking of these modalities are urgently needed. This chapter will address clinical presentation, aetiology, diagnosis and treatment of both upper and lower gastrointestinal bleeding in the elderly.

Clinical correlates and drug treatment of residents with stroke in long-term care

BACKGROUND AND PURPOSE

Stroke incidence increases with age, and stroke survivors often require nursing home placement. Characteristics of these residents and factors associated with the secondary drug prevention of stroke in nursing homes have yet to be explored.

METHODS

We used a population-based data set of all nursing home residents in 5 states (1992 to 1995). We identified 53 829 (20.4%) with a diagnosis of stroke on the Minimum Data Set assessment. We considered aspirin, dipyridamole, ticlopidine, or warfarin alone or in combination as secondary drug prevention. We used logistic regression modeling to identify independent predictors of drug treatment.

RESULTS

Sixty-seven percent of stroke survivors were not receiving drug therapy for stroke prevention. Among those treated, most received aspirin alone (16%) or warfarin alone (10%). Independent predictors of drug treatment included comorbid conditions (eg, hypertension, atrial fibrillation, depression, Alzheimer's disease, dementia, gastrointestinal bleeding, and peptic ulcer disease). Those over the age of 85 years were less likely to be treated than those 65 to 74 years of age (odds ratio [OR], 0.86; 95% confidence interval [CI], 0.82 to 0.91); black residents were less likely to be treated than whites (OR, 0.80; 95% CI, 0.75 to 0.85); and those with severe cognitive (OR, 0.63; 95% CI, 0.60 to 0.67) or physical impairment (OR, 0.69; 95% CI, 0.64 to 0.75) were also less likely to receive drug treatment.

CONCLUSIONS

Stroke is highly prevalent in long-term care. Despite the increased risk of subsequent stroke in the elderly, many are not being treated. The choice to treat or not to treat may be influenced by age, comorbidity, race/ethnicity, and cognitive or physical functioning.

Gastrointestinal bleeding in the elderly patient

The elderly patient with acute gastrointestinal bleeding requires a management approach that attends to age-dependent demands, such as functional status, the independent impact of functional status on outcomes such as short term mortality, and the consent process. This review examines issues such as patient triage, resuscitation, diet and medications, anticoagulation, endoscopy and conscious sedation, informed consent in the impaired patient, and discharge planning in light of these age-dependent demands.

Bleeding peptic ulcer: An evolving role for surgical intervention

Early surgical intervention was previously advocated in patients > 60 years with bleeding peptic ulcer presenting with haemodynamic instability or ongoing transfusion requirements. It is, however, well recognized that emergency surgical intervention with its inherent risks must be reserved for highly selected patients in whom endoscopy initially fails to control exsanquinating haemorrhage or in whom life-threatening bleeding recurs. Therapeutic endoscopy for bleeding ulcer has led to a remarkable decline in rebleeding rates, the need for emergency surgery and mortality. Octogenarians are at risk, particularly when ulcer size exceeds 2 cm. Poor surgical candidates make up two-thirds of patients with major ulcer bleeding and operation is to be avoided if at all possible. Medical therapy with proton pump inhibitor and subsequent eradication of Helicobacter pylori following endoscopic treatment has been shown to be beneficial to outcomes. Should surgery be deemed necessary, it is likely that laparoscopic techniques to control bleeding, with or without the addition of an acid-reducing procedure, will find a role in haemodynamically stable patients undergoing operation on an early elective basis.
