Novel and Simple Criteria for Predicting Mortality of Peptic Ulcer Disease.

ABSTRACT: Objective Conventional risk scores of peptic ulcer disease (PUD) are based on many parameters, and their application in clinical practice is therefore limited. The aim of this study was to establish simple and reliable criteria for predicting PUD-associated mortality. Methods A total of 499 patients with PUD were divided into 2 groups: the training cohort (n=333) and the validation cohort (n=166). To minimize selection bias due to missing values, we used imputed datasets generated by the multiple imputation method (training-cohort dataset, n=33,300; validation-cohort dataset, n=16,600). Results In the training-cohort dataset, the heart rate-to-systolic blood pressure ratio (HR/SBP) and serum albumin (s-Alb) level were significant independent predictive factors for mortality according to the multivariate analysis [HR/SBP, odds ratio (OR): 1.72; 95% confidence interval (CI), 1.06-2.80, p=0.028; s-Alb, OR: 0.23, 95% CI, 0.11-0.51, p<0.001]. The model comprising HR/SBP and s-Alb was able to detect mortality due to PUD with an area under the curve (AUC) of 0.855. In the validation-cohort dataset, this model also showed good efficacy with an AUC of 0.835. The novel criteria combining HR/SBP and s-Alb developed by a decision tree analysis showed 73.3% sensitivity and 87.6% specificity for predicting mortality in the total-cohort dataset. Our criteria were superior to the Glasgow Blatchford and Rockall scores and similar to the AIMS65 and Progetto Nazionale Emorragia Digestiva scores for predicting mortality. Conclusion The combination of the HR/SBP ratio and s-Alb level is a good predictor of mortality in patients with PUD.

Scoring systems for predicting clinical outcomes in peptic ulcer bleeding.

Project description:Few studies have focused on assessing the usefulness of scoring systems such as the Rockall score (RS), Glasgow-Blatchford score (GBS), and AIMS65 score for risk stratification and prognosis prediction in peptic ulcer bleeding patients. This study aimed to assess scoring systems in predicting clinical outcomes of patients with peptic ulcer bleeding. A total of 682 peptic ulcer bleeding patients who underwent esophagogastroduodenoscopy between January 2013 and December 2017 were found eligible for this study. The area under the receiver-operating characteristic curve (AUROC) of each score was calculated for predicting rebleeding, hospitalization, blood transfusion, and mortality. The median age of patients was 64 (interquartile range, 56-75) years. Of the patients, 74.9% were men, and 373 underwent endoscopic intervention. The median RS, GBS, and AIMS65 scores were significantly higher in patients who underwent endoscopic intervention than in those who did not. The AUROC of RS for predicting rebleeding was significantly higher than that of GBS (P = .022) or AIMS65 (P < .001). GBS best predicted the need for blood transfusion than either pre-RS (P = .013) or AIMS65 (P = .001). AIMS65 score showed the highest AUROC for mortality (0.652 vs. 0.622 vs. 0.691). RS was significantly associated with rebleeding (odds ratio, 1.430; P < .001) and overall survival (hazard ratio, 1.217; P < .001). The RS, GBS, and AIMS65 scoring systems are acceptable tools for predicting clinical outcomes in peptic ulcer bleeding. RS is an independent prognostic factor of rebleeding and overall survival.

Predictors of mortality in the elderly after open repair for perforated peptic ulcer disease.

Project description:BackgroundAs the U.S. population ages and the number of emergent surgical repairs for perforated peptic ulcer disease (PUD) rise, contemporary national data evaluating operative outcomes for open surgical repair for perforated PUD among the elderly are lacking.Materials and methodsThe National Surgical Quality Improvement Program (2007-2014) was queried for patients ≥65 y who underwent open surgical repair for perforated PUD. The primary outcome was 30-d mortality. Secondary outcomes included 30-d postoperative complications. Univariate and multivariable regression analyses were performed.ResultsOverall, 2131 patients underwent open surgical repair for perforated PUD. Among those who died, more used steroids preoperatively (15% versus 9%, P = 0.001) and fewer were independent preoperatively (55% versus 83%, P < 0.0001) compared to those who were alive 30-d postoperatively. Common postoperative complications were septic shock (15%) and pneumonia (12%). The overall 30-d mortality rate was 17.7%, with more deaths in subsequent decades of life (65-75 y 13% versus 75-84 y 18% versus >85 y 24%, P < 0.0001). After adjustment for other factors, mortality was significantly associated with older age (85+ versus 65-74 y) (odds ratio [OR], 1.5; 95% confidence interval [CI], 0.8, 1.7), dependent functional status preoperatively ([OR], 0.2; 95% CI, 0.2, 0.3), and American Society of Anesthesiologist classification ≥4 (OR, 3.2; 95% CI, 2.4, 4.3).ConclusionsAt U.S. hospitals, open surgical repair, the accepted treatment of perforated PUD, among the elderly is associated with significant 30-d morbidity and mortality rates that are unacceptably high in our contemporary era. Furthermore, mortality rates are associated with older age. Therefore, as the elderly population continues to increase in the United States, preoperative, perioperative, and postoperative measures must be taken to reduce this high morbidity and mortality rates.

Perforated peptic ulcer.

Project description:Perforated peptic ulcer is a common emergency condition worldwide, with associated mortality rates of up to 30%. A scarcity of high-quality studies about the condition limits the knowledge base for clinical decision making, but a few published randomised trials are available. Although Helicobacter pylori and use of non-steroidal anti-inflammatory drugs are common causes, demographic differences in age, sex, perforation location, and underlying causes exist between countries, and mortality rates also vary. Clinical prediction rules are used, but accuracy varies with study population. Early surgery, either by laparoscopic or open repair, and proper sepsis management are essential for good outcome. Selected patients can be managed non-operatively or with novel endoscopic approaches, but validation of such methods in trials is needed. Quality of care, sepsis care bundles, and postoperative monitoring need further assessment. Adequate trials with low risk of bias are urgently needed to provide better evidence. We summarise the evidence for perforated peptic ulcer management and identify directions for future clinical research.

Epstein-Barr virus association with peptic ulcer disease.

Project description:Background. Helicobacter pylori (HP) infection and nonsteroidal anti-inflammatory drugs (NSAID) use are considered the main risk to develop peptic ulcer disease (PUD). However, PUD also occurs in the absence of HP infection and/or NSAID use. Recently, we have found evidence that Epstein-Barr virus (EBV) reactivation increases the risk to develop premalignant and malignant gastric lesions. Objective. To study a possible association between EBV and PUD. Methods. Antibodies against an EBV reactivation antigen, HP, and the HP virulence factor CagA were measured in sera from 207 Mexican subjects, controls (healthy individuals, n = 129), and PUD patients (n = 78, 58 duodenal and 20 gastric ulcers). Statistical associations were estimated. Results. Duodenal PUD was significantly associated with high anti-EBV IgG titers (p = 0.022, OR = 2.5), while anti-EBV IgA was positively associated with gastric PUD (p = 0.002, OR = 10.1). Conclusions. Our study suggests that EBV reactivation in gastric and duodenal epithelium increases the risk to develop PUD.

Evaluation of clinical factors and three scoring systems for predicting mortality in perforated peptic ulcer patients, a retrospective study.

Project description:Background/objectiveEarly identification of mortality risk in perforated peptic ulcer (PPU) patients is important for triage and risk stratification. This study aimed to compare clinical and laboratory factors and three scoring systems to predict mortality in PPU patients.MethodsRetrospective data on PPU patients at M. Djamil Hospital who underwent emergency laparotomy repair surgery were collected from December 2018 to May 2021. The data included demographics, clinical characteristics, and three scoring systems. Data analysis used bivariate, multivariate, and ROC analysis.ResultsA total 72 patients were included and mortality rate was 52.8%. Bivariate analysis showed a significant association between age (p = 0.029), onset of illness (p = 0.001), alteration of consciousness (p = <0.001), respiratory rate (p = 0.04), duration of surgery (p = 0.040), preoperative shock (p = 0.049), preoperative creatinine (p = <0.001), Boey's scores (p = 0.002), ASA (p = 0.001), and qSOFA scores (p = <0.001) with mortality in PPU patients. From multivariate analysis, the strongest clinical factors associated with mortality were alteration of consciousness (p = <0.001) and preoperative creatinine (p = 0.001). Receiver Operating Characteristic (ROC) analysis showed the area under the curve (AUC) of Boey's Score 0.73, ASA classification 0.69, qSOFA score 0.77, alteration of consciousness 0.74, and preoperative creatinine 0.78.ConclusionPreoperative creatinine and altered consciousness had the strongest association with mortality in PPU patients. The qSOFA score predicted mortality better than Boey's score and ASA classification. Preoperative creatinine was the best single predictor of mortality.

Association between fibromyalgia syndrome and peptic ulcer disease development.

Project description:PurposeThe correlation of fibromyalgia syndrome (FMS) with peptic ulcer disease (PUD) is unclear. We therefore conducted a cohort study to investigate whether FMS is correlated with an increased risk of PUD.MethodsIn this study, we established an FMS cohort comprising 26068 patients aged more than 20 years who were diagnosed with FMS from 2000 to 2011. Furthermore, we established a control cohort by randomly choosing 104269 people without FMS who were matched to the FMS patients by gender, age, and index year. All patients were free of PUD at the baseline. Cox proportional hazard regressions were performed to compute the hazard ratio of PUD after adjustment for demographic characteristics and comorbidities.ResultsThe prevalence of comorbidities was significantly higher in the FMS patients than in the controls. The incidence of PUD was 29.8 and 19.4 per 1000 person-years in the FMS and control cohorts, respectively. In addition, the FMS cohort exhibited a 1.40-fold higher risk of PUD (95% confidence interval = 1.35-1.45) compared with the control cohort. After control for confounding factors, the medications (selective serotonin reuptake inhibitors, serotonin-norepinephrine reuptake inhibitors, and antidepressants) taken by the FMS patients did not increase the risk of PUD.ConclusionFMS patients exhibit a higher risk of PUD than that of patients without FMS.

Seasonal variation of peptic ulcer disease, peptic ulcer bleeding, and acute pancreatitis: A nationwide population-based study using a common data model.

Project description:AbstractAlthough gastrointestinal diseases are reported at various times throughout the year, some particular seasons are associated with a higher incidence of these diseases. This study aimed to identify the seasonal variations of peptic ulcer (PU), peptic ulcer bleeding (PUB), and acute pancreatitis (AP) in South Korea.We conducted a retrospective, observational cohort study of all subjects aged >18 years between 2012 and 2016 using the Health Insurance Review and Assessment-National Patient Samples database, previously converted to the standardized Observational Medical Outcomes Partnership-Common Data Model. We assessed the overall seasonal variations of PU, PUB, and AP and further analyzed seasonal variations according to age and sex subgroups.In total, 14,626 patients with PU, 3575 with PUB, and 9023 with AP were analyzed for 5 years. A clear seasonal variation was noted in PU, with the highest incidence rate during winter, the second highest during spring, the third highest during summer, and the lowest incidence during autumn for 5 years (P < .001). PUB also showed significant seasonal fluctuations, with winter peak for 4 years, except 1 year, which had a spring peak (P < .001). However, AP showed no clear seasonal variations (P = .090). No significant differences in the seasonal variation of PU, PUB, and AP were observed according to sex and age subgroups (<60 years vs ≥60 years).Seasonal variation of PU and PUB should be considered when determining allocation of available health care resources.

Effects of Insomnia on Peptic Ulcer Disease Using Mendelian Randomization.

Project description:ObjectivesObservational studies indicate that insomnia may increase risk of peptic ulcer disease (PUD). Our purpose is to clarify the possible causal relationship between insomnia and PUD by Mendelian randomization analyses.MethodsWe carried out analyses using summary statistics data for genetic variants reported from a GWAS of insomnia (N = up to 1,331,010 individuals) and from a GWAS of PUD (N = up to 456,327 individuals). Three Mendelian randomization approaches were used to explore whether insomnia might play a causal role in PUD, and pathway and functional enrichment analyses were conducted to anticipate the underlying mechanisms.ResultsConventional Mendelian randomization analysis showed clear causality between insomnia and PUD; 1 SD increased insomnia incident was related to a 19% higher risk of PUD (P = 6.69 × 10-16; OR, 1.19 (95% CI, 1.14-1.24)). The associations between insomnia and PUD were consistent in the other two analyses performed using the weighted median method (P = 7.75 × 10-7; OR, 1.16 (95% CI, 1.09-1.23)) and MR-Egger regression (P = 5.00 × 10-3; OR, 1.27 (95% CI, 1.07-1.50)). Moreover, no evidence indicated a reverse causality between PUD events and insomnia symptoms. Pathway and functional enrichment analyses indicated that the mechanisms of insomnia effect on PUD may be through various ways, such as the immune system and oxidative stress.ConclusionsThis Mendelian randomization study suggests insomnia as a causal risk factor for PUD. The potential mechanisms included may be immune and oxidative stress. These findings indicate that improving sleep quality could have substantial health benefits.

Opposing time trends of peptic ulcer and reflux disease.

Project description:BACKGROUND: Gastritis associated hypochlorhydria may be protective against gastro-oesophageal reflux disease. It was hypothesised that the historic decline in Helicobacter pylori infection resulted in a decline in peptic ulcer and a concomitant risk in reflux disease. AIMS: To study the time trends of peptic ulcer and reflux disease. METHODS: Hospitalisation rates were analysed using the computerised database of the US Department of Veterans Affairs from 1970 until 1995. Death rates were calculated from the Vital Statistics of the United States. RESULTS: From 1970 to 1995, hospitalisation rates for gastric and duodenal ulcer, as well as gastric cancer fell, while the hospitalisation rates for gastro-oesophageal reflux disease and those for oesophageal adenocarcinoma rose significantly. Similar time trends were observed with respect to the death rates. There were notable ethnic differences. White subjects incurred higher rates of reflux disease and oesophageal adenocarcinoma and lower rates of gastric ulcer or cancer compared with non-whites. CONCLUSIONS: The ethnic variations and the opposing time trends of gastroduodenal versus oesophageal disease are consistent with the hypothesis that the declining infection rates of H pylori in the general population have led to a rise in the occurrence of gastro-oesophageal reflux disease and associated oesophageal adenocarcinoma.

CagA and VacA polymorphisms are associated with distinct pathological features in Helicobacter pylori-infected adults with peptic ulcer and non-peptic ulcer disease.

Project description:Polymorphic variability in Helicobacter pylori factors CagA and VacA contributes to bacterial virulence. The presence of one CagA EPIYA-C site is an independent risk factor for gastroduodenal ulceration (odds ratio [OR], 4.647; 95% confidence interval [CI], 2.037 to 10.602), while the presence of the vacA i1 allele is a risk factor for increased activity (OR, 5.310; 95% CI, 2.295 to 12.287) and severity of gastritis (OR, 3.862; 95% CI, 1.728 to 8.632).
