Abstract
UNLABELLED Oral bisphosphonates and direct oral anticoagulants are related to upper gastrointestinal ulcers. The present study investigated whether concomitant use of these drugs increase the risk of upper gastrointestinal ulcers and report no increased risk of upper gastrointestinal ulcers compared to the use of either drug alone, when individuals with previous upper gastrointestinal ulcers are excluded. INTRODUCTION This study examines whether concomitant use of oral bisphosphonates (oBP) and direct oral anticoagulants (DOAC) increases the risk of peptic ulcers more than any drug alone. METHODS A population-based cohort study was performed. We sampled a cohort of oBP and DOAC users from a sample of 2,622,742 individuals, consisting of diabetes patients and age- and gender-matched controls, obtained from the Danish National Patient Register. The exposures were concomitant use of oBP and DOAC and single use of DOAC and single use of oBP. The primary endpoint was the first incident peptic ulcer. Information on exposure and outcome were collected from national registries. The period of observation was from 01.01.2008 until 31.12.2018. Unadjusted and adjusted Cox regressions were performed. RESULTS 8077 individuals received concomitant treatment with DOAC and oBP; 96,451 individuals used DOAC and no oBP; and 118,675 used oBP and no DOAC. The mean duration of follow-up was 1.9 years for concomitant users, 2.5 years for DOAC users, and 4.5 years for oBP users. A total of 4742 individuals with incident peptic ulcers were collected. We observed an increased risk of incident ulcer in users of DOAC and oBP compared to single DOAC treatment in the adjusted analysis (HR = 1.23, 95% CI: 1.03; 1.48). However, the effects were abolished when excluding individuals with a previous ulcer. We observed an increased risk of incident ulcer in users of DOAC and oBP compared to users of oBP in the adjusted model (HR = 1.34, 95% CI: 1.11; 1.63). CONCLUSION Based on our results, concomitant use of oBP and DOAC is associated with a slight increase in the risk of peptic ulcers compared to either drug alone. The prescribing physician should weigh the slight increased risk of ulcer in concomitant users of oBP and DOAC with beneficial reductions in stroke and fractures.

Abstract
Background and Aim Endoscopic differentiation between malignant and benign gastric ulcers (GU) affects further evaluation and prognosis. The aim of our study was to evaluate a deep learning algorithm for discrimination between benign and malignant GU in a database of endoscopic ulcer images. Methods We retrospectively collected consecutive upper gastrointestinal endoscopy images of GU performed between 2011 and 2019 at the Sheba Medical Center. All ulcers had a corresponding histopathology result of either benign peptic ulcer or gastric adenocarcinoma. A convolutional neural network (CNN) was trained to classify the images into either benign or malignant. Endoscopies from 2011 to 2017 were used for training (2011-2015) and validation (2016-2017). Hyper-parameters, image augmentation and pre-training on Google images obtained images were evaluated on the validation data. Held-out data from 2018 to 2019 was used for testing the final model. Results Overall, the Sheba dataset included 1978 GU images; 1894 images from benign GU and 84 images of malignant ulcers. The final CNN model showed an AUC 0.91 (95% CI 0.85-0.96) for detecting malignant ulcers. For cut-off probability 0.5, the network showed a sensitivity of 92% and specificity of 75% for malignant ulcers. Conclusion Our study displays the applicability of a CNN model for automated evaluation of gastric ulcers images for malignant potential. Following further research, the algorithm may improve accuracy of differentiating benign from malignant ulcers during endoscopies and assist in patients' stratification, allowing accelerated patients management and individualized approach towards surveillance endoscopy.

Abstract
Peptic ulcer disease (PUD) is caused by many sociodemographic and economic risk factors other than H. pylori infection. However, no studies reported an association between PUD and the number of household members. We showed the number of family members affected by PUD based on sex in a Korean population. This cross-sectional study used 1998–2009 data from the Korea National Health and Nutrition Examination Survey of the Korea Centers for Disease Control and Prevention. Multiple binary logistic regression models adjusted for confounders were constructed to analyze the association of PUD with the number of household members. The number of household members was associated with PUD, age, body mass index (BMI), waist circumference, systolic blood pressure, hemoglobin, glucose, location (urban/rural), income, education level, stress, current drinking, and smoking in both sexes. Men with other household members had a higher PUD risk compared to men or women living alone (reference), and the opposite was observed for women. Men with 4 household members had a higher PUD risk than men living alone in the model adjusted for age, BMI, income, location, education, and stress (OR = 2.04 [95% CI 1.28–3.27], p value = .003). Women with more than 6 household members had a lower PUD risk than women living alone in the adjusted model (OR = 0.50 [0.33–0.75], p value = .001). Women with more household members had a lower PUD risk. However, more men had PUD than women regardless of the number of household members.

Abstract
PURPOSE To report the computed tomography (CT) findings of acute peptic ulcer disease (PUD) and to evaluate the usefulness of contrast media for diagnosis. METHODS This retrospective study included 51 patients diagnosed with acute gastric peptic ulcer by endoscopy. Using a κ analysis, two radiologists independently reviewed contrast-enhanced emergency CTs performed within 24 h of endoscopy. Evaluation findings included low-attenuation wall thickening, focal wall thickening, focal luminal outpouching, perigastric fat stranding, ascites, adjacent lymphadenopathy, and high-density gastric contents. Of the 51 patients, 48 underwent both non-contrast-enhanced and contrast-enhanced CT, and two radiologists also evaluated the presence or absence of these findings on a non-contrast-enhanced CT. McNemar's test was used to evaluate the contrast media's usefulness. RESULTS Interobserver variability of perigastric fat stranding revealed substantial agreement between evaluators, and other findings had almost perfect agreement. High-density gastric contents were the most recognized findings (60%). Low-attenuation focal wall thickening and focal luminal outpouching were observed in relatively large numbers (~50%) of the cases on contrast-enhanced CT. The CT examinations using contrast media provided significantly higher detectability of low-attenuation wall thickening and focal luminal outpouching than CT examinations without using contrast media. CONCLUSION Acute PUD can be suspected in patients with nonspecific abdominal symptoms in whom emergency CT shows high-density gastric contents, focal low-attenuation wall thickening, and/or focal luminal outpouching. Our study showed that contrast media are useful for diagnosis.

Abstract
Gastric ulcer is a prevalent disease with various etiologies, including non-steroidal anti-inflammatory drugs (NSAIDs), stress conditions, and alcohol, resulting in an inflammatory condition in the gastric mucosa. The aim of this study was to explore the protective effects of modafinil on gastric erosions induced by indomethacin, water-immersion stress, and alcohol in rats and to evaluate the role of nitric oxide (NO) pathway. Animals were allocated to the three experimental models of gastric ulcer – indomethacin (30 mg/kg PO), water-immersion stress, and ethanol (5 ml/kg PO). Induction of gastric ulcer in all models caused an increase in J-score (macroscopic assessment), biochemical markers, including tumor necrosis factor-alpha (TNF-α), interleukin-1beta (IL-1β), and myeloperoxidase (MPO), and microscopic destructions. Administration of modafinil (50 and 100 mg/kg i. p) significantly improved J-score in the indomethacin (P < 0.05) and stress models (P < 0.001). Moreover, the level of TNF-α IL-1β, and MPO was deceased after modafinil administration (P < 0.001). However, modafinil did not have any effects on gastric injury induced by ethanol. In addition, co-administration of L-NAME (a non-specific NO synthase inhibitor) and aminoguanidine (an inducible NO synthase inhibitor) with modafinil significantly neutralized the gastroprotective effect of modafinil in the indomethacin and water-immersion stress groups (P < 0.05, and P < 0.01; respectively), while 7-nitroindazole (a neuronal NO synthase inhibitor) did not show such reversing effects. In conclusion, modafinil possesses gastroprotective effects on the gastric lesions induced by indomethacin and stress, which are probably mediated via the inflammation inhibition and NO pathway modulation.

Abstract
Objectives The objective of this study was to examine the association of peptic ulcer disease (PUD), including gastric ulcer and duodenal ulcer, with obesity-related indices, nutrients, and blood parameters in Korean adults. Methods Data were obtained from the Second-Fourth Korean National Health and Nutrition Examination Survey (KNHANES II-IV). Binary logistic regression was carried out to analyze the association between PUD and all variables in the crude analysis; in a subsequent analysis, adjustments were made for age, region, house type, number of snacks per day, and number of household members. Results PUD exhibited the highest association with age in both men and women among all variables used in this study. In men, only body mass index was associated with PUD in both the crude and adjusted analyses. PUD was associated with weight, height, and fat in the crude analysis, but these associations disappeared after adjustment for confounders. Vitamin B2, hemoglobin, and glucose were related to PUD, but these associations became nonsignificant in the adjusted analysis. Water, vitamin C, and potassium were not associated with PUD in the crude analysis but were associated with PUD after adjustment for confounders. In women, systolic blood pressure and height were associated with PUD. PUD was also related to waist circumference, the waist-to-height ratio, fat, and cholesterol, but these associations became nonsignificant after adjustment for confounders. Vitamin C, protein, niacin, sodium, energy, vitamin B2, vitamin B1, and aspartate aminotransferases were associated with PUD in only the crude analysis. PUD was not associated with diastolic blood pressure, water, vitamin A, or glucose, but these factors were associated with the disease in the adjusted analysis. Conclusion Older age was a risk factor for PUD in Korean adults, and the association of PUD with most nutrients and anthropometric indices may differ according to gender.

Abstract
Objectives Peptic ulcer disease (PUD) is a common disorder, but whether an association exists between PUD and anthropometric indicators remains controversial. Furthermore, no studies on the association of PUD with anthropometric indices, blood parameters, and nutritional components have been reported. The aim of this study was to assess associations of anthropometrics, blood parameters, nutritional components, and lifestyle factors with PUD in the Korean population. Methods Data were collected from a nationally representative sample of the South Korean population using the Korea National Health and Nutrition Examination Survey. Logistic regression was used to examine associations of anthropometrics, blood parameters and nutritional components among patients with PUD. Results Age was the factor most strongly associated with PUD in women (p = <0.0001, odds ratio (OR) = 0.770 [0.683–0.869]) and men (p = <0.0001, OR = 0.715 [0.616–0.831]). In both crude and adjusted analyses, PUD was highly associated with weight (adjusted p = 0.0008, adjusted OR = 1.251 [95%CI: 1.098–1.426]), hip circumference (adjusted p = 0.005, adjusted OR = 1.198 [1.056–1.360]), and body mass index (adjusted p = 0.0001, adjusted OR = 1.303 [1.139–1.490]) in women and hip circumference (adjusted p = 0.0199, adjusted OR = 1.217 [1.031–1.435]) in men. PUD was significantly associated with intake of fiber (adjusted p = 0.0386, adjusted OR = 1.157 [1.008–1.328], vitamin B2 (adjusted p = 0.0477, adjusted OR = 1.155 [1.001–1.333]), sodium (adjusted p = 0.0154, adjusted OR = 1.191 [1.034–1.372]), calcium (adjusted p = 0.0079, adjusted OR = 1.243 [1.059–1.459]), and ash (adjusted p = 0.0468, adjusted OR = 1.152 [1.002–1.325] in women but not in men. None of the assessed blood parameters were associated with PUD in women, and only triglyceride level was associated with PUD in men (adjusted p = 0.0169, adjusted OR = 1.227 [1.037–1.451]). Discussion We found that obesity was associated with PUD in the Korean population; additionally, the association between nutritional components and PUD was greater in women than in men.

Abstract
Background: T-cell immunoglobulin and mucin domain protein-3 (Tim-3), an inhibitory immunoregulatory receptor, has been recently implicated in tumor biology and tumor-associated immune suppression. In the present study, expression of Tim-3 was evaluated in gastric cancer (GC) and peptic ulcer disease (PUD) at both mRNA and protein levels. Methods: A total of 133 gastric tissue biopsies, comprising 43 from GC cases, 48 from PUD and 42 from non-ulcer dyspepsia (NUD) serving as controls were collected. Additionally, non-neoplastic adjacent tissue biopsies were also obtained from 6 patients with GC. Infection with Helicobacter pylori was determined by the rapid urease test for all participants and H&E staining was conducted for GC and PUD patients. Tim-3 relative mRNA expression was determined by SYBR Green based Real-Time PCR using β-actin as a reference gene. Tim-3 protein expression was also studied by immunohistochemistry in 7 GC, 7 PUD and 10 NUD tissue samples. Results: Tim-3 was expressed at higher levels in GC (p=0.030) and PUD (p=0.022) cases compared to he NUD group. Among paired samples obtained from gastric cancer patients, tumor tissues showed elevated Tim-3 expression (p=0.019) in comparison with adjacent non-neoplastic biopsies. Tim-3 mRNA findings were supported by detection of more Tim-3 protein in cancerous (p=0.002) and ulcerative (p=0.01) tissues than in controls. Tim-3 was similarly expressed in H. pylori positive and negative cases. Conclusion: Higher Tim-3 expression in patients with gastric cancer and peptic ulcer implies that it might be involved in immune regulation and establishment of these gastrointestinal diseases. Targeted immunotherapy by blocking of inhibitory receptors like Tim-3 could be a promising approach for gastric cancer treatment.

Follow-up endoscopy for benign-appearing gastric ulcers has no additive value in detecting malignancy: It is time to individualise surveillance endoscopy. Gastric Cancer 2015; 18:803-9. [PMID: 25312052 DOI: 10.1007/s10120-014-0433-4] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2014] [Accepted: 09/16/2014] [Indexed: 02/07/2023]
Abstract
OBJECTIVE To determine the diagnostic accuracy of endoscopic follow-up for gastric ulcers. METHODS All cases of gastric ulcers diagnosed at our teaching hospital between September 2005 and November 2011 were reviewed. The cases were selected by using ENDOBASE, an endoscopy documentation system. The characteristics of the ulcers and their histology were analysed. RESULTS During the study period 321 cases with a gastric ulcer were diagnosed, including 214 benign ulcers (67 %) and 107 malignant ulcers (33 %). The mean age of the population was 71 years. In 200 patients (62 %) the ulcers were classified as benign appearing at the first endoscopy. However, in five of these patients, the ulcers eventually were malignant. In all of these five patients the index gastroscopy revealed a non-benign histology. Therefore, the sensitivity of a benign appearance of the ulcer in combination with histology at the first endoscopy is 100 % to rule out malignancy. In 121 patients (38 %) the ulcers were explicitly labelled as potentially malignant in the report of the first endoscopy. Of these potentially malignant-appearing ulcers, 102 (84 %) were indeed malignant as confirmed by histology. The other 19 ulcers (16 %) were benign at follow-up. The sensitivity of the three potential malignant characteristics at endoscopy was: dirty base 79 %, elevated border 94 % and irregular border 91 %. The specificity was 93, 82 and 89 %, respectively. The median diameter of the ulcers was significantly higher in the malignant group compared to the benign ulcer group (p < 0.0001). The accuracy of endoscopic malignancy diagnosis was as follows: sensitivity of 0.98 and specificity 0.84, positive predictive value 0.84 and negative predictive value 0.98. In total, 546 gastroscopies were performed in these 321 patients, of which 225 were follow-up endoscopies. By not monitoring ulcers considered benign in both appearance and histology, 173 gastroscopies would not have been performed, resulting in a decline of 77 % of the follow-up endoscopies performed. CONCLUSION Endoscopic follow-up of gastric ulcers considered benign by appearance and with benign histology showed no additive value in detecting unsuspected malignancy in this study. This strategy could reduce health costs and save distress to patients.

Improving quality of care in peptic ulcer bleeding: nationwide cohort study of 13,498 consecutive patients in the Danish Clinical Register of Emergency Surgery. Am J Gastroenterol 2013; 108:1449-57. [PMID: 23732464 DOI: 10.1038/ajg.2013.162] [Citation(s) in RCA: 64] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2012] [Accepted: 04/23/2013] [Indexed: 12/11/2022]
Abstract
OBJECTIVES The treatment of peptic ulcer bleeding (PUB) is complex, and mortality remains high. We present results from a nationwide initiative to monitor and improve the quality of care (QOC) in PUB. METHODS All Danish hospitals treating PUB patients between 2004 and 2011 prospectively registered demographic, clinical, and prognostic data. QOC was evaluated using eight process and outcome indicators, including time to initial endoscopy, hemostasis obtainment, proportion undergoing surgery, rebleeding risks, and 30-day mortality. RESULTS A total of 13,498 PUB patients (median age 74 years) were included, of which one-quarter were in-hospital bleeders. Preadmission use of anticoagulants, multiple coexisting diseases, and the American Society of Anesthesiologists scores increased between 2004 and 2011. Considerable improvements were observed for most QOC indicators over time. Endoscopic treatment was successful with primary hemostasis achieved in more patients (94% in 2010-2011 vs. 89% in 2004-2006, relative risk (RR) 1.06 (95% confidence intervals 1.04-1.08)), endoscopy delay for hemodynamically unstable patients decreased during this period (43% vs. 34% had endoscopy within 6 h, RR 1.33 (1.10-1.61)), and fewer patients underwent open surgery (4% vs. 6%, RR 0.72 (0.59-0.87)). After controlling for time changes in prognostic factors, rebleeding rates improved (13% vs. 18%, adjusted RR 0.77 (0.66-0.91)). Crude 30-day mortality was unchanged (11% vs. 11%), whereas adjusted mortality decreased nonsignificantly over time (adjusted RR 0.89 (0.78-1.00)). CONCLUSIONS QOC in PUB has improved substantially in Denmark, but the 30-day mortality remains high. Future initiatives to improve outcomes may include earlier endoscopy, having fully trained endoscopists on call, and increased focus on managing coexisting disease.

Abstract
PURPOSE Incidence rate (IR) estimates for peptic ulcer disease (PUD) vary widely among studies. We conducted a systematic review to quantify and examine the discrepancies. METHODS Of 4780 articles identified from PubMed and EMBASE databases, 31 published in the last three decades that had reported IRs of PUD in the general population were included. Random effects meta-analysis and meta-regression were performed to calculate pooled estimates and to identify sources of heterogeneity. RESULTS The pooled IR estimate per 1000 person-years was 0.90 (95% confidence interval: 0.78-1.04) for uncomplicated PUD, 0.57 (0.49-0.65) for peptic ulcer bleeding, 0.10 (0.08-0.13) for gastrointestinal perforations, and 3.18 (2.05-4.92) for nonspecific PUD. Within specific outcomes definitions, IR estimates were significantly lower in studies with restriction to hospitalized cases, case validation, and case ascertainment directly from hospital or clinical sources versus computerized health care databases. Younger age, female sex, and later calendar time were also associated with lower PUD incidence. CONCLUSIONS We found that the IR of uncomplicated PUD was in the order of one case per 1000 person-years in the general population, and that the IR of peptic ulcer complications was around 0.7 cases per 1000 person-years. Comparisons of IR estimates among studies need to take into account disease definition and other study characteristics, particularly whether outcome validation was performed in computerized claims. The use of claims to identify PUD cases might overestimate the IR by around 45%.

Abstract
AIM: To investigate the prevalence and risk factors of asymptomatic peptic ulcer disease (PUD) in a general Taiwanese population.
METHODS: From January to August 2008, consecutive asymptomatic subjects undergoing a routine health check-up were evaluated by upper gastrointestinal endoscopy. Gastroduodenal mucosal breaks were carefully assessed, and a complete medical history and demographic data were obtained from each patient. Logistic regression analysis was conducted to identify independent risk factors for asymptomatic PUD.
RESULTS: Of the 572 asymptomatic subjects, 54 (9.4%) were diagnosed as having PUD. The prevalence of gastric ulcer, duodenal ulcer and both gastric and duodenal ulcers were 4.7%, 3.9%, and 0.9%, respectively. Multivariate analysis revealed that prior history of PUD [odds ratio (OR), 2.0, 95% CI: 1.3-2.9], high body mass index [body mass index (BMI) 25-30: OR, 1.5, 95% CI: 1.0-2.2; BMI > 30 kg/m2: OR, 3.6, 95% CI: 1.5-8.7] and current smoker (OR, 2.6, 95% CI: 1.6-4.4) were independent predictors of asymptomatic PUD. In contrast, high education level was a negative predictor of PUD (years of education 10-12: OR, 0.5, 95% CI: 0.3-0.8; years of education > 12: OR, 0.6, 95% CI: 0.3-0.9).
CONCLUSION: The prevalence of PUD in asymptomatic subjects is 9.4% in Taiwan. Prior history of PUD, low education level, a high BMI and current smoker are independent risk factors for developing asymptomatic PUD.

Abstract
CONTEXT Solidago chilensis Meyen (Asteraceae) is widely used in South America in traditional medicine as an anti-inflammatory and diuretic, and to treat gastrointestinal disorders. However, no scientific evidence exists in literature to corroborate the therapeutic use of the plant. Despite its traditional uses, no reports are available on the safety of this utilization or on the relationship between the pharmacological activities and its phytochemical compounds. OBJECTIVE This study investigates for the first time the acute toxicity and the gastroprotective effect of the aqueous extract from inflorescences of S. chilensis. MATERIALS AND METHODS The gastroprotective activity was evaluated in mice subjected to ethanol-induced gastric ulcer model at 125, 250, 400, 800, 1200, and 2000 mg/kg doses. Acute toxicity study was performed at one dose of 2000 mg/kg. At the end of the exposure behavioral and functional parameters and motor activity were assessed in all animals. RESULTS Results demonstrated that the extract exhibited a significant antiulcer activity when given at 125-2000 mg/kg (P <0.05), but did not show acute toxicity in mice treated with 2000 mg/kg p.o. DISCUSSION AND CONCLUSION This study demonstrated that the oral administration of S. chilensis aqueous extract prevents the formation of gastric lesions caused by an aggressive factor as ethanol but does not produce toxicity by acute exposure in mice. These promising results support a better pharmacological study of S. chilensis as a potential antiulcerogenic species for studies targeted towards the development of antiulcerogenic agents.

Abstract
BACKGROUND Peptic ulcer disease (PUD) is most commonly associated with Helicobacter pylori infection and the use of acetylsalicylic acid (ASA) and nonsteroidal anti-inflammatory drugs (NSAIDs). The management of H. pylori infection has improved radically in recent years; however, the prescription of ASA and NSAIDs has increased over the same period. AIM To evaluate the current global incidence and prevalence of PUD by systematic review of the literature published over the last decade. METHODS Systematic searches of PubMed, EMBASE and the Cochrane library. RESULTS The annual incidence rates of PUD were 0.10-0.19% for physician-diagnosed PUD and 0.03-0.17% when based on hospitalization data. The 1-year prevalence based on physician diagnosis was 0.12-1.50% and that based on hospitalization data was 0.10-0.19%. The majority of studies reported a decrease in the incidence or prevalence of PUD over time. CONCLUSIONS Peptic ulcer disease remains a common condition, although reported incidence and prevalence are decreasing. This decrease may be due to a decrease in H. pylori-associated PUD.

Abstract
We investigated the prevalence of peptic ulcer in dyspeptic patients in China to analyze the influence of age, sex, and Helicobacter pylori (H. pylori) infection. The results showed that the prevalence of gastric and duodenal ulcer increased with age. In patients under 60 years old, the prevalence of duodenal and gastric ulcers in females was markedly lower than that in males, especially the prevalence of duodenal ulcer. The prevalence of duodenal ulcer and gastric ulcer in H. pylori-infected patients was markedly higher than in patients without H. pylori infection. In the patients under 60 years old, sex differences were still seen in both H. pylori-positive and H. pylori-negative patients. The prevalence of gastric and duodenal ulcers was markedly increased with age in both H. pylori-positive and H. pylori-negative patients. Multivariate logistic regression analysis showed that age, male sex, and H. pylori infection were three independent risk factors for gastric and duodenal ulcers.

Abstract
Barrett's esophagus (BE) is a chronic complication associated with gastroesophageal reflux disease. The ICD-9-CM code used for BE, 530.2, is also used for patients with 'ulcer of the esophagus.' We aimed to determine if the ICD-9-CM code of 530.2 is reliable for identifying cases of Barrett's esophagus within databases for research purposes. We reviewed the records of all patients assigned code 530.2 at two university medical center hospitals and a veterans' administration hospital over a cumulative 16-year period. Billing records provided information about where the code was assigned, whether it was a major or minor diagnosis, and if the code was assigned on multiple occasions for each patient. Histology and endoscopy records were reviewed to confirm the diagnosis of Barrett's esophagus. Among 435 patients with code 530.2 in their records, 354 (82%) had an esophageal biopsy reported and 393 (90%) had an endoscopy report available for review. Only 182 (42%) had specialized intestinal metaplasia documented in a biopsy from an area of salmon-colored mucosa arising above the esophagogastric junction (51% of those with histology available). There were 288 patients (66%) with an endoscopic diagnosis of Barrett's esophagus (73% of those with an endoscopy reported). Variables associated with documented specialized intestinal metaplasia were age > or = 60 (OR 2.3; 95% CI 1.4-3.7), multiple assignments of 530.2 (OR 3.2; 95% CI 2.0-5.0), and assignment of 530.2 in a gastrointestinal (GI) clinic or an endoscopy unit (OR 3.5; 95% CI 2.0-6.3). The positive predictive value of the code being assigned in a GI location was 48% (95% CI 43-54%). Therefore, ICD-9-CM code of 530.2 is not specific for the diagnosis of Barrett's esophagus. The usage of code 530.2 in a GI setting was not sufficiently predictive of BE to be reliable for rigorous epidemiological studies.

An economic model of long-term use of celecoxib in patients with osteoarthritis. BMC Gastroenterol 2007; 7:25.

Abstract
Background Previous evaluations of the cost-effectiveness of the cyclooxygenase-2 selective inhibitor celecoxib (Celebrex, Pfizer Inc, USA) have produced conflicting results. The recent controversy over the cardiovascular (CV) risks of rofecoxib and other coxibs has renewed interest in the economic profile of celecoxib, the only coxib now available in the United States. The objective of our study was to evaluate the long-term cost-effectiveness of celecoxib compared with nonselective nonsteroidal anti-inflammatory drugs (nsNSAIDs) in a population of 60-year-old osteoarthritis (OA) patients with average risks of upper gastrointestinal (UGI) complications who require chronic daily NSAID therapy. Methods We used decision analysis based on data from the literature to evaluate cost-effectiveness from a modified societal perspective over patients' lifetimes, with outcomes expressed as incremental costs per quality-adjusted life-year (QALY) gained. Sensitivity tests were performed to evaluate the impacts of advancing age, CV thromboembolic event risk, different analytic horizons and alternate treatment strategies after UGI adverse events. Results Our main findings were: 1) the base model incremental cost-effectiveness ratio (ICER) for celecoxib versus nsNSAIDs was $31,097 per QALY; 2) the ICER per QALY was $19,309 for a model in which UGI ulcer and ulcer complication event risks increased with advancing age; 3) the ICER per QALY was $17,120 in sensitivity analyses combining serious CV thromboembolic event (myocardial infarction, stroke, CV death) risks with base model assumptions. Conclusion Our model suggests that chronic celecoxib is cost-effective versus nsNSAIDs in a population of 60-year-old OA patients with average risks of UGI events.

Abstract
AIM: To identify and evaluate the relative impact of H pylori infection and other risk factors on the occurrence of gastric ulcer (GU), duodenal ulcer (DU) and gastritis in Turkish patients.
METHODS: A total of 4471 patients (48.3% female) out of 4863 attended the Samatya hospital in Istanbul (June 1999 - October 2003) were included. The records of H pylori status (CLO-test), endoscopic findings of GU, DU and gastritis, personal habits (smoking, alcohol intake) and medication [non-steroidal anti-inflammatory drugs (NSAIDs), aspirin intake] were analyzed using multi-way frequency analysis.
RESULTS: We have found that GU in the presence of H pylori had significant association with aspirin (P = 0.0001), alcohol (P = 0.0090) and NSAIDs (P = 0.0372). DU on the other hand had significant association with aspirin/ smoking/NSAIDs (P = 0.0259), aspirin/alcohol (P = 0.0002) and aspirin/smoking (P = 0.0233), also in the presence of H pylori. In the absence of H pylori GU had significant association with alcohol/NSAIDs (P = 0.0431), and NSAIDs (P = 0.0436). While DU in the absence of H pylori had significant association with smoking/alcohol/ NSAIDs (P = 0.0013), aspirin/NSAIDs (P = 0.0334), aspirin/alcohol (P = 0.0360).
CONCLUSION: In the presence of H pylori, aspirin, alcohol and NSAIDs intake act as an independent risk factors that had an augmenting impact on the occurrence of GU and only together on the occurrence of DU in Turkish patients.

Abstract
The impact of risk factors on the development of peptic ulcers has been shown to vary among different populations. We sought to establish a correlation between these factors and their involvement in the occurrence of peptic ulcers for which a canonical correlation analysis was applied. We included 7,014 patient records (48.6% women, 18.4% duodenal ulcer [DU], 4.6% gastric ulcer [GU]) of those underwent upper gastroendoscopy for the last 5 years. The variables measured are endoscopic findings (DU, GU, antral gastritis, erosive gastritis, pangastritis, pyloric deformity, bulbar deformity, bleeding, atrophy, Barret esophagus and gastric polyp) and risk factors (age, gender, Helicobacter pylori infection, smoking, alcohol, and nonsteroidal anti-inflammatory drugs [NSAIDs] and aspirin intake). We found that DU had significant positive correlation with bulbar deformity (P=2.6 x 10(-23)), pyloric deformity (P=2.6 x 10(-23)), gender (P=2.6 x 10(-23)), H. pylori (P=1.4 x 10(-15)), bleeding (P=6.9 x 10(-15)), smoking (P=1.4 x 10(-7)), aspirin use (P=1.1 x 10(-4)), alcohol intake (P=7.7 x 10(-4)), and NSAIDs (P=.01). GU had a significantly positive correlation with pyloric deformity (P=1,6 x 10(-15)), age (P=2.6 x 10(-14)), bleeding (P=3.7 x 10(-8)), gender (P=1.3 x 10(-7)), aspirin use (P=1.1 x 10(-6)), bulbar deformity (P=7.4 x 10(-4)), alcohol intake (P=.03), smoking (P=.04), and Barret esophagus (P=.03). The level of significance was much higher in some variables with DU than with GU and the correlations with GU in spite of being highly significant the majority, were small in magnitude. In conclusion, Turkish patients with the following endoscopic findings bulbar deformity and pyloric deformity are high-risk patients for peptic ulcers with the risk of the occurrence of DU being higher than that of GU. Factors such as H. pylori, smoking, alcohol use, and NSAIDs use (listed in a decreasing manner) are risk factors that have significant impact on the occurrence of DU; aspirin has a significant impact on both DU and GU.

Abstract
UNLABELLED Peptic ulcer epidemiology changes as the proportion of Helicobacter pylori infected people decreases, use of nonsteroidal anti-inflammatory drugs (NSAID) increases, and the proportion of elderly persons increases. OBJECTIVES To describe incidence and prognosis of uncomplicated and complicated peptic ulcer patients in Funen County 1993-2002. METHODS Data on endoscopies, gastric and duodenal operations, and related peptic ulcer diagnoses were extracted from four population-based databases covering a period from 1974 to 2002. All citizens of Funen County (population 470,000) who between 1993 and 2002 had a peptic ulcer diagnosed for the first time were identified. RESULTS Between 1993 and 2002 the incidence of uncomplicated duodenal ulcer decreased from 0.55/1,000 person-years (95% CI 0.49-0.62) to 0.37 (0.31-0.43), uncomplicated gastric ulcer decreased from 0.56 (0.49-0.63) to 0.40 (0.34-0.46), and perforated ulcer decreased from 0.14 (0.11-0.18) to 0.08 (0.06-0.11). The incidence of bleeding peptic ulcer was stable with 0.55 (0.49-0.62) in 1993 and 0.57 (0.51-0.64) in 2002. The proportion of possible NSAID-related incident peptic ulcers increased from 320/827 (39%) in 1993 to 363/686 (53%) in 2002 (p < 0.01). A total of 3,233 patients with incident complicated peptic ulcer (9,927 person-years) and 4,421 patients with incident uncomplicated peptic ulcer (17,773 person-years) was followed for up to 10 yr. The first month following newly diagnosed complicated ulcer the standardized mortality rate was 37.1 (33.4-41.1) during the next 11 months it was 5.1 (4.6-5.6), and in the following years it was 2.6 (2.4-2.8). The corresponding figures for incident uncomplicated peptic ulcer was 11.6 (9.6-13.9), 4.0 (3.6-4.4), and 2.5 (2.3-2.7). CONCLUSION During the period, incidence of peptic ulcers decreased and an increasing proportion was related to NSAID. Mortality is high.

Abstract
OBJECTIVE The objective of this study was to examine the relationship of work loss associated with gastro- the relationship of work loss associated with gastro- the relationship of work loss associated with gastro-esophageal reflux disease (GERD) and peptic ulcer disease (GERD) and peptic ulcer disease (PUD) in a large population of employed individuals in the United States (US) and quantify the individuals in the United States (US) and quantify the economic impact of these diseases to the employer. METHODS A proprietary database that contained work place absence, disability and workers' compensation data in addition to prescription drug and medical claims was used to answer the objectives. Employees with a medical claim with an ICD-9 code for GERD or PUD were identified from 1 January 1997 to 31 December 2000. A cohort of controls was identified for the same time period using the method of frequency matching on age, gender, industry type, occupational status, and employment status. Work absence rates and health care costs were compared between the groups after adjusting for demo graphic, and employment differences using analysis of covariance models. RESULTS There were significantly lower (p < 0.05) prescription, and outpatient costs in the controls compared to the disease groups, although the eta-square values were very low. The mean work absence attributed to sick days was 2.8 (+/- 2.3) for controls, 3.4 (+/- 2.5) for GERD, 3.2 (+/- 2.6) for PUD, and 3.2 (+/- 2.3) days for GERD + PUD. For work loss, a significantly higher (p < 0.05) rate of adjusted all-cause absenteeism and sickness-related absenteeism were observed between the disease groups versus the controls. In particular, controls had an average of 1.2 to 1.6 days and 0.4 to 0.6 lower all-cause and sickness-related absenteeism compared to the disease groups. The incremental economic impact projected to a hypothetical employed population was estimated to be $3441 for GERD, $1374 for PUD, and $4803 for GERD + PUD per employee per year compared to employees without these diseases. CONCLUSIONS Direct medical cost and work absence in employees with GERD, PUD and GERD + PUD represent a significant burden to employees and employers.

Abstract
BACKGROUND Peptic ulcer epidemiology has changed considerably within the past century. The aim of this study was to assess the 11-year cumulative incidence of peptic ulcer disease and examine the relationship between ulcer incidence and psychosocial and genetic factors. METHODS A random sample of 2416 Danish adults with no history of peptic ulcer disease residing in Copenhagen County, Denmark, attended a population-based prospective cohort study in 1983 and 1994. All participants reported whether they had had an ulcer diagnosed within the observation period. Information on socio-economic factors, family history of peptic ulcer disease (PUD) and lifestyle practices was obtained from a questionnaire. Lewis blood group antigens were assessed from blood samples and Helicobacter pylori infection status was determined with an in-house IgG ELISA. RESULTS The overall 11-year cumulative incidence proportion of PUD was 2.9% (95% CI (2.2; 3.6)), i.e. 1.6% (95% CI (1.1; 2.1)) for duodenal ulcer, and 1.3% (95% CI (0.8; 1.7)) for gastric ulcer. Poor socio-economic status increased the risk of PUD independently of H. pylori infection (odds ratio 2.7, 95% CI (1.1; 6.1)) and accounted for 17% of all ulcer cases. High physical activity at work increased the risk of PUD in people infected with H. pylori (odds ratio 2.6, 95% CI (0.8; 8.0)). Family history of PUD or Lewis blood group antigens did not relate to ulcer incidence. CONCLUSIONS Poor socio-economic status is an important risk factor for PUD that exerts its effect independently of H. pylori infection. Strenuous work may increase the risk of PUD in people with H. pylori infection. Genetic factors do not influence the risk of PUD in Danish adults.

Abstract
OBJECTIVE During proton pump inhibitor (PPI) use, in clinical trials, headache is one of the most frequently reported adverse events (frequency 1.3 to 8.8%), while results of one observational study indicate that headache is the fifth most frequently reported adverse event (incidence densities 2.5 to 4.6 per 1000 patient-months of exposure). However, there are no observational studies performed regarding the occurrence and features of headache during use of PPIs in daily practice. For this reason this study was set up with the aim to assess the incidence and characteristics of headache and to investigate possible associated co-factors in PPI users in daily practice. DESIGN Data were used from a prospective, observational study in which 10 008 lansoprazole users were followed over time. The study was designed according to the Safety Assessment of Marketed Medicines guidelines. A nested case-control design was used to compare PPI users reporting headache or not. RESULTS The frequency of headache was 2.5% in users of lansoprazole and the incidence density was 7.2 per 1000 patient-months of PPI lansoprazole use. Two-thirds of patients with headache had tension headache and one-third had migraine. The analysis of co-factors revealed that women, patients with previous use of analgesics and patients reporting several adverse events, were at risk to develop headache during PPI use. Patients with headache also, significantly more often, reported diarrhoea, nausea and dizziness. A discontinuation of PPI therapy resulted in a cessation or reduction of the headache in 80.0% (20 of 25). CONCLUSIONS As can be expected, headache was reported less frequently in this study compared with clinical trials with lansoprazole. The incidence density was comparable with other observational data of lansoprazole and omeprazole users. Besides several commonly accepted co-factors such as female gender and a history of analgesic use, we also found the reporting of other adverse events to be associated with the reporting of headache during lansoprazole use. The cessation of headache after a discontinuation of use of the PPI and the observed dose relationship suggested that headache was indeed an adverse effect of lansoprazole use.

Abstract
BACKGROUND Despite the fact that the main cause of duodenal ulcer incidence and recurrence is the Helicobacter pylori bacterium, more than 80% of Helicobacter pylori-infected people never develop an ulcer. Diet may be one of the most important environmental factors contributing to duodenal ulcer. AIMS To explore the role of diet in causation, treatment and prevention of duodenal ulcer recurrence. METHODS All research papers published in English from 1966 to October 1999 present in Medline, involving human subjects, and having duodenal ulcer as outcome, entered the review. RESULTS AND CONCLUSIONS Soluble fibre from fruit and vegetables seem to be protective against duodenal ulcer and refined sugars a risk factor. The role of fibre in the treatment and prevention of recurrence of duodenal ulcer is uncertain, as is that of essential fatty acids. However, none of the epidemiological studies on the relationship between diet and duodenal ulcer disease controlled for Helicobacter pylori.

Abstract
BACKGROUND Although Helicobacter pylori has been identified as a major cause of chronic gastritis, not all infected patients develop ulcers, suggesting that other factors such as lifestyle may be critical to the development of ulcer disease. OBJECTIVE To investigate the role physical activity may play in the incidence of peptic ulcer disease. METHODS The participants were men (n = 8,529) and women (n = 2,884) who attended the Cooper Institute for Aerobics Research, Dallas, Texas, between 1970 and 1990. The presence of gastric or duodenal ulcer disease diagnosed by a physician was determined from a mail survey in 1990. Participants were classified into 3 physical activity groups according to information provided at the baseline clinic visit (before 1990): active, those who walked or ran 10 miles or more a week; moderately active, those who walked or ran less than 10 miles a week or did another regular activity; and the referent group consisting of those who reported no regular physical activity. RESULTS With the use of gender-specific proportional hazards regression models that could be adjusted for age, smoking, alcohol use, body mass index, and self-reported tension, active men had a significantly reduced risk for duodenal ulcers (relative hazard [95% confidence interval] for the active group, 0.38 [0.15-0.94], and 0.54 [0.30-0.96] for the moderately active group). No association was found between physical activity and gastric ulcers for men or for either type of ulcer for women. CONCLUSION Physical activity may provide a nonpharmacologic method of reducing the incidence of duodenal ulcers among men.
