The influence of etiologic factors on clinical outcome in patients with peptic ulcer bleeding

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.

Outcomes of patients hospitalized with peptic ulcer disease diagnosed in acute upper endoscopy

OBJECTIVES

The incidence and complications of peptic ulcer disease (PUD) have declined, but mortality from bleeding ulcers has remained unchanged. The aims of the current study were to evaluate the significance of PUD among patients admitted for acute upper endoscopy and to evaluate the survival of PUD patients.

PATIENTS AND METHODS

In this prospective, observational cohort study, data on 1580 acute upper endoscopy cases during 2012-2014 were collected. A total of 649 patients were included with written informed consent. Data on patients' characteristics, living habits, comorbidities, drug use, endoscopy and short-term and long-term survival were collected.

RESULTS

Of all patients admitted for endoscopy, 147/649 (23%) had PUD with the main symptom of melena. Of these PUD patients, 35% had major stigmata of bleeding (Forrest Ia-IIb) in endoscopy. Patients with major stigmata had significantly more often renal insufficiency, lower level of blood pressure with tachycardia and lower level of haemoglobin, platelets and ratio of thromboplastin time. No differences in drug use, Charlson comorbidity class, BMI, smoking or alcohol use were found. Of the PUD patients, 31% were Helicobacter pylori positive. The 30-day mortality was 0.7% (95% confidence interval: 0.01-4.7), 1-year mortality was 12.9% (8.4-19.5) and the 2-year mortality was 19.4% (13.8-26.8), with no difference according to major or minor stigmata of bleeding. Comorbidity (Charlson>1) was associated with decreased survival (P=0.029) and obesity (BMI≥30) was associated with better survival (P=0.023).

CONCLUSION

PUD is still the most common cause for acute upper endoscopy with very low short-term mortality. Comorbidity, but not the stigmata of bleeding, was associated with decreased long-term survival.

Chronic obstructive pulmonary disease is associated with increased recurrent peptic ulcer bleeding risk

BACKGROUND

The association between chronic obstructive pulmonary disease (COPD) and the risk of recurrent peptic ulcer bleeding (PUB) remains unclear. In this study, we compared the risk of recurrent PUB between patients with and those without COPD.

METHODS

Using the Taiwan National Health Insurance Research Database, we first selected patients newly diagnosed with PUB in 2002-2009. Two groups comprising 13,732 COPD cases and 13,732 non-COPD matched controls were created using propensity score matching, thereby making the differences in basic demographics, medication use, and disease conditions between the two groups negligible. Cox proportional hazard regression was used to evaluate the risk of recurrent PUB during the follow-up period.

RESULTS

The cumulative recurrence rate of PUB was significantly higher in the patients with COPD than in the non-COPD matched controls (2years: 10.8% vs 9.3%; 6years: 18.3% vs 15.7%, P all <0.05), with an adjusted hazard ratio (HR) of 1.17 (95% confidence interval [CI], 1.08-1.26, P<0.001) and 1.19 (95% CI, 1.12-1.26, P<0.001) within 2-year and 6-year follow-ups, respectively. Patients with COPD using steroids were at a marginally higher risk of recurrent PUB than those who did not use steroids. Multivariate stratified analysis revealed similar results in many subgroups.

CONCLUSIONS

The risk of recurrent PUB is higher in patients with COPD than in patients without COPD.

Early eradication has a lower risk of peptic ulcer bleeding in Helicobacter pylori-infected chronic kidney disease patients

BACKGROUND

End stage renal disease (ESRD) contributes to a higher mortality rate in peptic ulcer bleeding (PUB) patients. A crucial question is whether early Helicobacter pylori (H. pylori) eradication therapy is necessary for H. pylori-infected chronic kidney disease (CKD) patients. To explore whether H. pylori eradication therapy has a lower risk of PUB at the pre-ESRD stage than at the ESRD stage.

METHODS AND PATIENTS

Patients meeting 2 criteria were defined as newly diagnosed ESRD cases: (1) patients diagnosed with ESRD and receiving regular dialysis between 2000 and 2009; and (2) patients with no history of dialysis between 1997 and 1999. We divided the study participants into pre-ESRD and ESRD groups on the basis of the time between H. pylori eradication and dialysis. The date of the first PUB diagnosis was defined as the primary endpoint. Stratified Cox proportional hazard regression analysis was used to estimate the effect of H. pylori eradication at the pre-ESRD and ESRD stage on the occurrence of PUB.

RESULTS

We included 476 patients in the pre-ESRD cohort and 476 patients in the matched ESRD cohort. After adjustment for age, sex, the presence of comorbidities, and medication use, the hazard ratio of PUB was 0.66 times less in the pre-ESRD cohort than in the ESRD cohort. Factors such as Charlson's score more than 3, and nonsteroidal anti-inflammatory drugs were associated with an increased risk of PUB.

CONCLUSION

Our result supports that early H. pylori eradication has a lower risk of PUB in H. pylori-infected CKD patients.

Value of standardized treatment mode for peptic ulcer

AIM: To evaluate the effect of standardized treatment mode for peptic ulcer.

METHODS: One hundred and eighty-nine patients with peptic ulcer were divided into a standardized treatment group (n = 96) and a control group (n = 93). The standardized treatment group received standardized treatment regimen, and the control group was treated with conventional therapy. After treatment, the two groups were compared regarding Helicobacter pylori (H. pylori) eradication, ulcer healing, ulcer recurrence, patient compliance, satisfaction score, and rate of disease knowledge awareness.

RESULTS: The H. pylori eradication rate and ulcer cure rate were significantly higher in the standardized treatment group than in the control group (84.21% vs 58.89%, 42.11% vs 28.89%, P < 0.05). The rate of ulcer recurrence did not differ significantly between the standardized treatment group and the control group (12.63% vs 17.78%, P > 0.05). Average score of therapeutic compliance in the 185 patients was 6.69 ± 1.35, among which the score was significantly lower in the standardized treatment group than in the control group (7.22 ± 1.34 vs 6.17 ± 1.37, P < 0.05). The satisfaction degree was also significantly higher in the standardized treatment group than in the control group (4.31 ± 0.99 vs 3.06 ± 1.26, P < 0.05). The standardized treatment group presented higher rate of disease knowledge awareness than the control group (70.53% vs 46.67%, P < 0.05).

CONCLUSION: The standardized treatment mode for peptic ulcer could effectively increase the eradication rate of H. pylori, ulcer healing rate, patient's knowledge about the disease, medication compliance and patient treatment satisfaction, representing an effective strategy for prevention and treatment of peptic ulcer.

North vs south differences in acute peptic ulcer hemorrhage in Croatia: hospitalization incidence trends, clinical features, and 30-day case fatality

Aim

To assess the seven-year trends of hospitalization incidence due to acute peptic ulcer hemorrhage (APUH) and associated risk factors, and examine the differences in these trends between two regions in Croatia.

Methods

The study collected sociodemographic, clinical, and endoscopic data on 2204 patients with endoscopically confirmed APUH who were admitted to the Clinical Hospital Center “Sestre Milosrdnice,” Zagreb and Clinical Hospital Center Split between January 1, 2005 and December 31, 2011. We determined hospitalization incidence rates, 30-day case fatality rate, clinical outcomes, and incidence-associated factors.

Results

No differences were observed in APUH hospitalization incidence rates between the regions. Age-standardized one-year cumulative APUH hospitalization incidence rate calculated using the European Standard Population was significantly higher in Zagreb than in Split region (43.2/100 000 vs 29.2/100,000). A significantly higher APUH hospitalization incidence rates were observed in the above 65 years age group. Overall 30-day case fatality rate was 4.9%.

Conclusion

The hospitalization incidence of APUH in two populations did not change over the observational period and it was significantly higher in the Zagreb region. The incidence of acute duodenal ulcer hemorrhage also remained unchanged, whereas the incidence of acute gastric ulcer hemorrhage increased. The results of this study allow us to monitor epidemiological indicators of APUH and compare data with other countries.

Mortality in high-risk patients with bleeding Mallory-Weiss syndrome is similar to that of peptic ulcer bleeding. Results of a prospective database study

OBJECTIVE

The aim of this study was to identify the predictive factors influencing mortality in patients with bleeding Mallory-Weiss syndrome in comparison with peptic ulcer bleeding.

MATERIAL AND METHODS

Between January 2005 and December 2009, 281 patients with endoscopically confirmed Mallory-Weiss syndrome and 1530 patients with peptic ulcer bleeding were consecutively evaluated. The 30-day mortality and clinical outcome were related to the patients' demographic data, endoscopic, and clinical characteristics.

RESULTS

The one-year cumulative incidence for bleeding Mallory-Weiss syndrome was 7.3 cases/100,000 people and for peptic ulcer bleeding 40.4 cases/100,000 people. The age-standardized incidence for both bleeding Mallory-Weiss syndrome and peptic ulcer bleeding remained unchanged during the observational five-year period. The majority of patients with bleeding Mallory-Weiss syndrome were male patients with significant overall comorbidities (ASA class 3-4). Overall 30-day mortality rate was 5.3% for patients with bleeding Mallory-Weiss syndrome and 4.6% for patients with peptic ulcer bleeding (p = 0.578). In both patients with bleeding Mallory-Weiss syndrome and peptic ulcer bleeding, mortality was significantly higher in patients over 65 years of age and those with significant overall comorbidities (ASA class 3-4).

CONCLUSION

The incidence of bleeding Mallory-Weiss syndrome and peptic ulcer bleeding has not changed over a five-year observational period. The overall 30-day mortality was almost equal for both bleeding Mallory-Weiss syndrome and peptic ulcer bleeding and was positively correlated to older age and underlying comorbid illnesses.
