Gastroscopic characterisation and prevalence of gastric ulcer syndrome in working mules in Colombia

BACKGROUND

The existing literature does not contain information about the prevalence of gastric ulcers in mules, and on the potential associations between the presence of ulcers and work load, work type, diet, sex, age and body condition score (BCS).

OBJECTIVE

To estimate the prevalence and factors associated with mule gastric ulcer syndrome (MGUS) and evaluate its distribution in both mule squamous gastric disease (MSGD) and mule glandular gastric disease (MGGD) mucosa in a population of mules in Colombia.

STUDY DESIGN

Observational, cross-sectional.

METHODS

A total of 97 clinically healthy mules of different ages and locations in the province of Antioquia (Colombia) were included in this study. The mules were involved in agricultural activities (i.e., riding, pack and ranch mules) at the time of the study. The animals underwent gastroscopic evaluation, and ulcer scores from 0 to 4 were assigned based on severity, with scores ≥2 indicating clinical relevance. The presence or absence of ulcer in the squamous and/or glandular region of the stomach was recorded. Data related to work type, work load and diet, as well as sex, age and BCS were recorded for each mule. Pearson's chi-square test was used to determine the association between the outcomes and explanatory variables of the study (p ≤ 0.05). The results of the risk estimations were presented as odds ratios (ORs) with 95% confidence intervals (CIs).

RESULTS

The frequency of MGUS in the study population was 42%. Most of the lesions were located in the squamous region of the stomach (27%), mainly in the margo plicatus, and 20% were located in the glandular region, mainly in the fundus and pyloric antrum. Six animals showed lesions in both squamous and glandular regions. Work load was the only variable associated with the presence of MGUS (OR: 1.98; 95% CI: 0.49-0.96) and MSGD (OR: 1.78; 95% CI: 0.36-0.67). Nevertheless, the findings did not provide any significant risk assessment result, nor did they reveal any significant interactions among the other variables.

MAIN LIMITATIONS

This study used convenience sampling from a limited geographic region, and multivariate analysis was not performed, one of the exclusion criteria was the use of nonsteroidal anti-inflammatory drugs, which means that the effect of these drugs can no longer be evaluated.

CONCLUSIONS

MGUS occurs in mules subjected to agricultural work, the risk factors associated with EGUS do not appear to be significant in mules and other equids subjected to the same conditions, in this region. Further research is needed to define the differential dynamics of MGUS in comparison with the findings in horses.

Risk Factors for Mortality in Emergently Admitted Patients with Acute Gastric Ulcer: An Analysis of 15,538 Patients in National Inpatient Sample, 2005-2014

Background: Patients admitted emergently with a primary diagnosis of acute gastric ulcer have significant complications including morbidity and mortality. The objective of this study was to assess the risk factors of mortality including the role of surgery in gastric ulcers. Methods: Adult (18−64-year-old) and elderly (≥65-year-old) patients admitted emergently with hemorrhagic and/or perforated gastric ulcers, were analyzed using the National Inpatient Sample database, 2005−2014. Demographics, various clinical data, and associated comorbidities were collected. A stratified analysis was combined with a multivariable logistic regression model to assess predictors of mortality. Results: Our study analyzed a total of 15,538 patients, split independently into two age groups: 6338 adult patients and 9200 elderly patients. The mean age (SD) was 50.42 (10.65) in adult males vs. 51.10 (10.35) in adult females (p < 0.05). The mean age (SD) was 76.72 (7.50) in elderly males vs. 79.03 (7.80) in elderly females (p < 0.001). The percentage of total deceased adults was 1.9% and the percentage of total deceased elderly was 3.7%, a difference by a factor of 1.94. Out of 3283 adult patients who underwent surgery, 32.1% had perforated non-hemorrhagic ulcers vs. 1.8% in the non-surgical counterparts (p < 0.001). In the 4181 elderly surgical patients, 18.1% had perforated non-hemorrhagic ulcers vs. 1.2% in the non-surgical counterparts (p < 0.001). In adult patients managed surgically, 2.6% were deceased, while in elderly patients managed surgically, 5.5% were deceased. The mortality of non-surgical counterparts in both age groups were lower (p < 0.001). The multivariable logistic regression model for adult patients electing surgery found delayed surgery, frailty, and the presence of perforations to be the main risk factors for mortality. In the regression model for elderly surgical patients, delayed surgery, frailty, presence of perforations, the male sex, and age were the main risk factors for mortality. In contrast, the regression model for adult patients with no surgery found hospital length of stay to be the main risk factor for mortality, whereas invasive diagnostic procedures were protective. In elderly non-surgical patients, hospital length of stay, presence of perforations, age, and frailty were the main risk factors for mortality, while invasive diagnostic procedures were protective. The following comorbidities were associated with gastric ulcers: alcohol abuse, deficiency anemias, chronic blood loss, chronic heart failure, chronic pulmonary disease, hypertension, fluid/electrolyte disorders, uncomplicated diabetes, and renal failure. Conclusions: The odds of mortality in emergently admitted geriatric patients with acute gastric ulcer was two times that in adult patients. Surgery was a protective factor for patients admitted emergently with gastric perforated non-hemorrhagic ulcers.

Epidemiology of perforating peptic ulcer: A population-based retrospective study over 40 years

BACKGROUND

The incidence of peptic ulcer disease has decreased during the last few decades, but the incidence of reported peptic ulcer complications has not decreased. Perforating peptic ulcer (PPU) is a severe form of the disease.

AIM

To assess trends in the incidence, presentation, and outcome of PPU over a period of 40 years.

METHODS

This was a single-centre, retrospective, cohort study of all patients admitted to Levanger Hospital, Norway, with PPU from 1978 to 2017. The patients were identified in the Patient Administrative System of the hospital using International Classification of Diseases (ICD), revision 8, ICD-9, and ICD-10 codes for perforated gastric and duodenal ulcers. We reviewed the medical records of the patients to retrieve data. Vital statistics were available for all patients. The incidence of PPU was analysed using Poisson regression with perforated ulcer as the dependent variable, and sex, age, and calendar year from 1978 to 2017 as covariates. Relative survival analysis was performed to compare long-term survival over the four decades.

RESULTS

Two hundred and nine patients were evaluated, including 113 (54%) men. Forty-six (22%) patients were older than 80 years. Median age increased from the first to the last decade (from 63 to 72 years). The incidence rate increased with increasing age, but we measured a decline in recent decades for both sexes. A significant increase in the use of acetylsalicylic acid, from 5% (2/38) to 18% (8/45), was observed during the study period. Comorbidity increased significantly over the 40 years of the study, with 22% (10/45) of the patients having an American Society of Anaesthesiologists (ASA) score 4-5 in the last decade, compared to 5% (2/38) in the first decade. Thirty-nine percent (81/209) of the patients had one or more postoperative complications. Both 100-day mortality and long-term survival were associated with ASA score, without significant variations between the decades.

CONCLUSION

Declining incidence rates occurred in recent years, but the patients were older and had more comorbidity. The ASA score was associated with both short-term mortality and long-term survival.

Changes of gastric ulcer bleeding in the metropolitan area of Japan

BACKGROUND

The two main causes of gastric ulcer bleeding are Helicobacter pylori (H. pylori) infection and ulcerogenic medicines, although the number of cases caused by each may vary with age. In Japan, the rate of H. pylori infection has fallen over the last decade and the number of prescriptions for non-steroidal anti-inflammatory drugs (NSAIDs) and antithrombotic drugs is increasing as the population ages. Methods of treatment for gastric ulcer bleeding have advanced with the advent of hemostatic forceps and potassium-competitive acid blocker (P-CAB). Thus, causes and treatments for gastric ulcer bleeding have changed over the last decade.

AIM

To examine the trends of gastric ulcer bleeding over 10 years in the metropolitan area of Japan.

METHODS

This is a single-center retrospective study. A total of 564 patients were enrolled from inpatients admitted to our hospital with gastric ulcer bleeding between 2006 and 2016. Age, medication history, H. pylori infection, method of treatment, rate of rebleeding, and the length of hospitalization were analyzed. Factors associated with gastric ulcer bleeding were evaluated using Fisher’s exact test, Pearson’s Chi-squared test or Student’s t-test as appropriate. The Jonckheere-Terpstra test was used to evaluate trends. A per-protocol analysis was used to examine the rate of H. pylori infection.

RESULTS

There was a significant increase in the mean age over time (P < 0.01). The rate of H. pylori infection tended to decrease over the study period (P = 0.10), whereas the proportion of patients taking antithrombotic agents or NSAIDs tended to increase (P = 0.07). Over time, the use of NSAIDs and antithrombotic drugs increased with age. By contrast, the rate of H. pylori infection during the study period fell with age. H. pylori-induced ulcers accounted for the majority of cases in younger patients (< 70 years old); however, the rate decreased with age (P < 0.01). The method of treatment trend has changed significantly over time. The main method of endoscopic hemostasis has changed from clipping and injection to forceps coagulation (P < 0.01), and frequently prescribed medicines have changed from proton pump inhibitor to P-CAB (P < 0.01). The rate of rebleeding during the latter half of the study was significantly lower than that in the first half.

CONCLUSION

These trends, gastric ulcers caused by ulcerogenic drugs were increasing with age and H. pylori-induced ulcers were more common in younger patients, were observed.

Gastroduodenal perforation in the pediatric population: a retrospective analysis of 20 cases

OBJECTIVE

The aim of this study was to investigate the pathogenesis, symptoms and individualized surgical management in pediatrics with gastroduodenal perforation (GDP).

METHODS

Patients diagnosed with GDP from January 2013 to December 2016 in our hospital were collected and divided into gastric perforation (GP) group and duodenal perforation (DP) group. Demographics, clinical events, etiological factors, symptoms, the time from symptom onset to operation, intraoperative findings and surgical procedures were analyzed. Follow-ups including ulcer, perforations occurrence, and digestive symptoms were carried out by out-patient review or telephones.

RESULTS

A total of 20 patients aged from 3 months to 14 years were enrolled in this study. The average age, main clinical presentations, size of perforations and operating time between two groups had no difference. The male to female ratio in DP group was higher than GP (P < 0.05). The high risk factor for DP was the use of dexamethasone, and for GP was HP infection. The most common site of perforation in DP group was duodenal bulb, and in GP group was pylorus area. Simple suture is the main management for both DP and GP, but distal gastrectomy combined with gastrojejunal Roux-en-Y anastomosis may be an alternative procedure for large perforation with diameter > 2 cm. The length of hospital days in GP group is shorter than DP group (P < 0.05). For follow-up, no patients had digestive symptoms.

CONCLUSIONS

The general condition had no difference between GP and DP patients. But the risk factors and surgical repair differ depending on the patient's fundamental illness and the complexity of the perforation.

[Current state of elective surgery for peptic ulcer]

AIM

To analyze the current state of elective surgery for peptic ulcer and to assess its significance for improving the results of treatment of this disease.

MATERIAL AND METHODS

The analysis included elective procedures for peptic ulcer performed in the surgical department of Tula Regional Clinical Hospital in the period from 2011 to 2015. These data were compared with those for the period 1996-2000 in order to objectively identify current changes in surgery for peptic ulcer. The interval between both periods was 10 years. The main group consisted of 47 patients with peptic ulcer who underwent surgery in 2011-2015. The control group included 254 patients who underwent similar procedures in 1996-2000.

RESULTS

Annual number of elective procedures for peptic ulcer decreased 5 times. There was advanced mean age in the main group, 29.8% of patients in the main group were older than 60 years, in the control group - 23%. Male/female ratio in the main group was 1:1, in the control group - 5:1. Prolonged ulcer history was observed in 10.6% of patients of the main group and 3.2% - in the control group. At the end of the last century, the greatest number of scheduled operations was performed for duodenal ulcer, now - for stomach ulcer. There was increased incidence of surgery for post-resection gastric syndrome (17 and 4.8% in both groups, respectively). We noted similar indications for elective surgical treatment of peptic ulcer in both groups. However, the negative feature of current period is significant augmentation of patients with decompensated pyloroduodenal stenosis. The structure of elective operations in 2011-2015 was characterized by significant proportion of decompensated complications of peptic ulcer as a result of prolonged medication. Prolonged postoperative hospital-stay and increased postoperative mortality were noted in the main group.

CONCLUSION

Reduced number of elective procedures for peptic ulcer is associated with changed structure of patients undergoing surgery. Unreasonable prolonged medication aggravates patient state and adversely affects the results of surgical treatment. The current state of elective surgery for peptic ulcer does not correspond to the objective to improve the results of treatment of this disease.

The value of oral contrast ultrasonography in the diagnosis of gastric cancer in elderly patients

BACKGROUND

This study aims to investigate the value of oral contrast ultrasonography (OCUS) in the diagnosis of gastric cancer in elderly patients.

METHODS

OCUS data obtained from patients ≥ 60 years old were retrospectively analyzed and compared with gastroscopy results.

RESULTS

Among the 12,716 subjects examined by OCUS, 5021 subjects were ≥ 60 years old, which accounted for 39.48% (5021/12,716). Gastritis, gastric polyp, benign ulcer, and gastric cancer were detected by OCUS in 1099 patients. Among them, 196 patients underwent gastroscopy. Furthermore, ulcerative lesions were detected in 32 patients by OCUS and in 51 patients by gastroscopy, and the coincidence rate was 62.74%. Among these patients, gastric cancer was diagnosed in 18 patients by OCUS with a detection rate of 1.64% (18/1099) and detected in 19 patients by gastroscopy with a diagnostic coincidence rate of 94.73% (18/19). Furthermore, benign ulcer was detected in 14 patients by OCUS and in 32 patients by gastroscopy, and the diagnostic coincidence rate was 43.75% (14/32).

CONCLUSION

OCUS helps to timely detect senile gastric cancer and can be used as a suitable technique for the detection of gastric diseases.

Association of gastric and duodenal ulcers with anthropometry and nutrients: Korean National Health and Nutrition Examination Survey (KNHANES II-IV) 2001-2009

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.

The WOMAC score can be reliably used to classify patient satisfaction after total knee arthroplasty

PURPOSE

The primary aim of this study was to define a classification in the WOMAC score after total knee arthroplasty (TKA) according to patient satisfaction. The secondary aims were to describe patient demographics for each level of satisfaction.

METHODS

A retrospective cohort consisting of 2589 patients undergoing a primary TKA were identified from an established arthroplasty database. Patient demographics, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and short form (SF) 12 scores were collected pre-operatively and 1 year post-operatively. In addition, patient satisfaction was assessed at 1 year with four responses: very satisfied, satisfied, dissatisfied or very dissatisfied. Receiver operating characteristic (ROC) curves were used to identify values in the components and total WOMAC scores that were predictive of each level of satisfaction, which were used to define the categories of excellent, good, fair and poor.

RESULTS

At 1 year, there were 1740 (67.5%) very satisfied, 572 (22.2%) satisfied, 190 (7.4%) dissatisfied and 76 (2.9%) very dissatisfied patients. ROC curve analysis identified excellent, good, fair and poor categories for the pain (> 78, 59-78, 44-58, < 44), function (> 72, 54-72, 41-53, < 41), stiffness (> 69, 56-69, 43-55, < 43) and total (> 75, 56-75, 43-55, < 43) WOMAC scores, respectively. Patients with lung disease, diabetes, gastric ulcer, kidney disease, liver disease, depression, back pain, with worse pre-operative functional scores (WOMAC and SF-12) and those with less of an improvement in the scores, had a significantly lower level of satisfaction.

CONCLUSION

This study has defined a post-operative classification of excellent, good, fair and poor for the components and total WOMAC scores after TKA. The predictors of level of satisfaction should be recognised in clinical practice and patients at risk of a lower level of satisfaction should be made aware in the pre-operative consent process.

Should asymptomatic young men with iron deficiency anemia necessarily undergo endoscopy?

BACKGROUND/AIMS

There has been no evidence for the necessity of endoscopy in asymptomatic young men with iron deficiency anemia (IDA). To determine whether endoscopy should be recommended in asymptomatic young men with IDA, we compared the prevalence of gastrointestinal (GI) lesions between young men (< 50 years) with IDA and those without IDA.

METHODS

We conducted a case-control study on asymptomatic young men aged < 50 years who underwent both esophagogastroduodenoscopy (EGD) and colonoscopy as part of a health checkup between 2010 and 2014.

RESULTS

Of 77,864 participants, 128 (0.16%) had IDA and 512 subjects without IDA were matched for several variables including age. Young men with IDA had a significantly higher proportion of colorectal cancer (CRC) (0.8% vs. 0.0%, p = 0.045), villous adenoma (0.8% vs. 0.0%, p = 0.045), and inflammatory bowel disease (IBD; 2.3% vs. 0.4%, p = 0.025) than those without IDA. Additionally, the prevalence of advanced colorectal neoplasia (ACRN) tended to be higher in subjects with IDA than in those without IDA (3.1% vs. 1.0%, p = 0.084). The prevalence of significant lower GI lesions including ACRN and IBD was higher in subjects with IDA than in those without IDA (5.5% vs. 1.4%, p = 0.011). Regarding upper GI lesions, a positive association with IDA was observed only for gastric ulcer (4.7% vs. 1.0%, p = 0.011).

CONCLUSION

GI lesions including CRC, villous adenoma, IBD, and gastric ulcer were more common in asymptomatic young men with IDA. Our results suggest that EGD and particularly colonoscopy should be recommended even in asymptomatic young men with IDA.

Acid suppression in patients treated with endoscopic therapy for the management of gastroesophageal varices: a systematic review and meta-analysis

BACKGROUND AND AIM

Endoscopic therapy is the cornerstone choice for the management of varices and variceal hemorrhage. The aim of the present systematic review and meta-analysis was to evaluate the efficacy of acid suppression in patients treated with endoscopic therapy for gastroesophageal varices.

METHODS

All eligible studies were searched via the PubMed, EMBASE, and Cochrane Library databases. Incidence of bleeding, mortality, ulcers, chest pain, and dysphagia after endoscopic therapy and length of stay were analyzed. Subgroup analyses were performed according to the types and major indications of endoscopic treatments. Odds ratios (ORs) with 95% confidence intervals (95%CIs) were calculated.

RESULTS

Nine studies with 1470 patients were included. Acid suppression could significantly decrease the incidence of bleeding (OR = 0.39, 95%CI: 0.19-0.81, P = 0.01) and diminish the ulcer size (OR = 0.78, 95%CI: 0.38-1.57, P = 0.48) after endoscopic therapy. The subgroup analyses showed that acid suppression could significantly decrease the incidence of bleeding in patients undergoing prophylactic EVL, rather than in patients undergoing therapeutic EVL. There was no significant difference in the incidence of mortality, ulcers, chest pain, and dysphagia and length of stay between patients treated with and without acid suppression.

CONCLUSION

Acid suppression might be considered in patients undergoing prophylactic EVL for gastroesophageal varices.

Clinical aspects of gastropathy development in patients with chronic obstructive pulmonary disease

OBJECTIVE

Introduction: Chronic obstructive pulmonary disease (COPD) is a one of the main reasons of disability and mortality in the world. The essential attention is dedicated to the combination of COPD and erosive/ulcer defects with the haemorrhage risk factor. The aim was to compare gastric acidity and mucoid secretion in patients with chronic obstructive pulmonary disease of gastropathy development.

PATIENTS AND METHODS

Materials and methods: 94 patients with gastroduodenal erosive and ulcerous defects combined with COPD were examined. More than 50 % of patients (over 20 pack-years) had a long smoking history. Control group including 20 healthy voluntiers.

RESULTS

Results: The mean age of patients was no difference in both groups. In regards to the severity of disease based on FEV1 30,9 % patients had mild obstruction and 69,1 % had moderate obstruction. Measurement of intragastric pH in patients with COPD and gastropathy showed the tendency of decreasing pH from 1,70±0,05 to 1,52±0,04 (р<0,05), while the pepsin level increased from 0,56±0,05 mg/ml to 0,86±0,07 mg/ml (р<0,01). At the same time the level of NANA decreased in cases of ulcerative defects (р<0,05).

CONCLUSION

Conclusions: The COPD combination with gastropathy leads to appearance of numerous erosions and ulcers in gastroduodenal zone that can be the reason of bleeding development. Long-term cigarette smoke exposure and high level of H.pylori infectoin are the main cause of gastroduodenal erosive and ulcerative defects in this comorbidities. The presence of erosions and ulcers is accompanied by a significant increase of an acid-peptic factor and a decrease of defense factor.

[Risk factors for adverse course of gastric and duodenal peptic ulcer]

OBJECTIVE

Introduction: High morbidity rate, frequent relapses, and significant economic losses give reasons for highlighting the peptic ulcer disease as the most topical medical-statistical problem. The aim of the study is to assess the influence of the main risk factors on the course of gastric and duodenal peptic ulcer.

PATIENTS AND METHODS

Materials and methods: We formed up the risk groups consisted of patients with 12 modified (4) and regular (8) factors, each characterized with its own signs and gradations. We performed the quantitative evaluation of the factors and scored the signs thereof, the results of which were used for determination of the most informative ones.

RESULTS

Results: Among the regular factors, we placed emphasis on gender, age, burdened heredity, and 0(I), Rh+ blood type. The risk of peptic ulcer in hereditary tainted young men of the working age with parental lineage (+2.3) and in males with 0(I) Rh+ blood type (+1.4) was proved. Helicobacter pylori (Hp) infection is a key contributor (a predictor of) to severity of the disease course (+9.7) among the modified risk factors. Negative effect of a concomitant pathology (+5.0), including hepatobiliary lesions (+3.8), hypertension (+4.0), and diabetes mellitus (+1.3) is also significant. Diet violation (+3.7), tobacco smoking (+3.2) and stress (+3.0) were ranked third.

CONCLUSION

Conclusions: The results of quantitative evaluation of the factors scoring suggest of the underlying H.pylori infection (the significance of which is growing along with the growth of the disease incidence) and irrational diet as the most informatively important ones. We have established the direct dependence between the most important peptic ulcer risk factors, severity of the disease, and duration and periodicity of treatment thereof.

Associations of Helicobacter pylori infection and peptic disease with diabetic mellitus: Results from a large population-based study

BACKGROUND

Evidence is conflicting regarding the association between Helicobacter pylori infection and diabetes mellitus. The study objective was to examine associations of H. pylori infection, gastric ulcers and duodenal ulcers, with diabetes mellitus.

METHODS

This cross-sectional study was undertaken using coded data from the computerized database of Maccabi Health Services in Israel, on 147,936 individuals aged 25-95 years who underwent the urea breath test during 2002-2012. Multiple logistic regression models were conducted, while adjusting for known risk factors for diabetes mellitus.

RESULTS

A H. pylori positive test was recorded for 76,992 (52.0%) individuals and diabetes for 12,207 (8.3%). The prevalence of diabetes was similar in individuals with and without H. pylori infection, but this association was modified (P for heterogeneity 0.049) by body mass index (BMI): adjusted odds ratio (aOR) 1.16 (95% confidence intervals (CI) 1.04-1.29) in persons with BMI<25 kg/m2 versus aOR 1.03 (95% CI 0.98-1.08) in persons with BMI≥25 kg/m2. Diabetes mellitus prevalence was higher in persons with gastric (aOR 1.20 (95% CI 1.06-1.34)) and duodenal ulcers (aOR 1.20 (95% CI 1.12-1.28)) compared to persons without these diagnoses.

CONCLUSIONS

In this large population-based study, we demonstrated significant positive associations, albeit of small magnitude, of H. pylori infection and peptic disease with diabetes. The long-term gastric inflammation and associated-damage to the gastric mucosa might play a role in such associations.

Increased blood cadmium levels were not associated with increased fracture risk but with increased total mortality in women: the Malmö Diet and Cancer Study

This study aimed to investigate if high levels of blood cadmium at baseline were associated with increased fracture risk during follow-up in middle-aged women. No increased fracture risk was observed during follow-up, but women with higher levels of cadmium had an increased overall mortality.

INTRODUCTION

Exposure to high levels of cadmium has been associated with an increased fracture risk. The aim was to investigate a perceived association between low levels of blood cadmium (B-Cd) at baseline and risk of first incident fracture.

METHODS

From the population-based Malmö Diet and Cancer Study Cardiovascular cohort, 2920 middle-aged women with available background questionnaire and B-Cd measurements were included. Women were divided into quartiles (Q) according to their cadmium levels (Cd-Q1 <0.18 μg/L, Cd-Q2 0.18-0.28 μg/L, Cd-Q3 0.28-0.51 μg/L, and Cd-Q4 >0.51 μg/L). National registries were analysed for prospective risk of fractures or death. Associations between B-Cd and fracture risk were assessed by survival analysis (Cox regression analysis).

RESULTS

In total, 998 first incident fractures occurred in women during a follow-up lasting 20.2 years (median) (12.5-21.2 years) (25th-75th percentile). Women in Cd-Q4 were more often current smokers than in Cd-Q1 78.4 vs. 3.3% (p < 0.001) and the number of cigarettes smoked per day correlated with B-Cd (r = 0.49; p < 0.001). The risk of fracture was not associated with baseline B-Cd in adjusted models. The hazard ratio (HR) Cd-Q4 vs. Cd-Q1 was 1.06 (95% confidence interval (CI) 0.89-1.27). In the multivariate Cox regression, independent variables for increased fracture risk were history of gastric ulcer and increasing age, whereas increasing body mass index (BMI) lowered fracture risk. Overall mortality was significantly higher for women with high B-Cd, HR 2.06 (95% CI 1.57-2.69).

CONCLUSIONS

Higher blood levels of cadmium did not increase fracture risk in middle-aged women but reduced overall survival.

Celecoxib for rheumatoid arthritis

BACKGROUND

Rheumatoid arthritis is a systemic auto-immune disorder that causes widespread and persistent inflammation of the synovial lining of joints and tendon sheaths. Presently, there is no cure for rheumatoid arthritis and treatment focuses on managing symptoms such as pain, stiffness and mobility, with the aim of achieving stable remission and improving mobility. Celecoxib is a selective non-steroidal anti-inflammatory drug (NSAID) used for treatment of people with rheumatoid arthritis.

OBJECTIVES

To assess the benefits and harms of celecoxib in people with rheumatoid arthritis.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase and clinical trials registers (ClinicalTrials.gov and the World Health Organization trials portal) to May 18, 2017. We also searched the reference and citation lists of included studies.

SELECTION CRITERIA

We included prospective randomized controlled trials (RCTs) that compared oral celecoxib (200 mg and 400 mg daily) versus no intervention, placebo or a traditional NSAID (tNSAID) in people with confirmed rheumatoid arthritis, of any age and either sex. We excluded studies with fewer than 50 participants in each arm or had durations of fewer than four weeks treatment.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by The Cochrane Collaboration.

MAIN RESULTS

We included eight RCTs with durations of 4 to 24 weeks, published between 1998 and 2014 that involved a total of 3988 adults (mean age = 54 years), most of whom were women (73%). Participants had rheumatoid arthritis for an average of 9.2 years. All studies were assessed at high or unclear risk of bias in at least one domain. Overall, evidence was assessed as moderate-to-low quality. Five studies were funded by pharmaceutical companies. Celecoxib versus placeboWe included two studies (N = 873) in which participants received 200 mg daily or 400 mg daily or placebo. Participants who received celecoxib showed significant clinical improvement compared with those receiving placebo (15% absolute improvement; 95% CI 7% to 25%; RR 1.53, 95% CI 1.25 to 1.86; number needed to treat to benefit (NNTB) = 7, 95% CI 5 to 13; 2 studies, 873 participants; moderate to low quality evidence).Participants who received celecoxib reported less pain than placebo-treated people (11% absolute improvement; 95% CI 8% to 14%; NNTB = 4, 95% CI 3 to 6; 1 study, 706 participants) but results were inconclusive for improvement in physical function (MD -0.10, 95% CI 0.29 to 0.10; 1 study, 706 participants).In the celecoxib group, 15/293 participants developed ulcers, compared with 4/99 in the placebo group (Peto OR 1.26, 95% CI 0.44 to 3.63; 1 study, 392 participants; low quality evidence). Nine (of 475) participants in the celecoxib group developed short-term serious adverse events, compared with five (of 231) in the placebo group (Peto OR 0.87 (0.28 to 2.69; 1 study, 706 participants; low quality evidence).There were fewer withdrawals among people who received celecoxib (163/475) compared with placebo (130/231) (22% absolute change; 95% CI 16% to 27%; RR 0.61, 95% CI 0.52 to 0.72; 1 study, 706 participants).Cardiovascular events (myocardial infarction, stroke) were not reported. However, regulatory agencies warn of increased cardiovascular event risk associated with celecoxib. Celecoxib versus tNSAIDsSeven studies (N = 2930) compared celecoxib and tNSAIDs (amtolmetin guacyl, diclofenac, ibuprofen, meloxicam, nabumetone, naproxen, pelubiprofen); one study included comparisons of both placebo and tNSAIDs (N = 1149).There was a small improvement, which may not be clinically significant, in numbers of participants achieving ACR20 criteria response in the celecoxib group compared to tNSAIDs (4% absolute improvement; 95% CI 0% less improvement to 8% more improvement; RR 1.10, 95% CI 0.99 to 1.23; 4 studies, 1981 participants). There was a lack of evidence of difference between participants in the celecoxib and tNSAID groups in terms of pain or physical function. Results were assessed at moderate-to-low quality evidence (downgraded due to risk of bias and inconsistency).People who received celecoxib had a lower incidence of gastroduodenal ulcers ≥ 3 mm (34/870) compared with those who received tNSAIDs (116/698). This corresponded to 12% absolute change (95% CI 11% to 13%; RR 0.22, 95% CI 0.15 to 0.32; 5 studies, 1568 participants; moderate quality evidence). There were 7% fewer withdrawals among people who received celecoxib (95% CI 4% to 9%; RR 0.73, 95% CI 0.62 to 0.86; 6 studies, 2639 participants).Results were inconclusive for short-term serious adverse events and cardiovascular events (low quality evidence). There were 17/918 serious adverse events in people taking celecoxib compared to 42/1236 among people who received placebo (Peto OR 0.71; 95% CI 0.39 to 1.28; 5 studies, 2154 participants). Cardiovascular events were reported in both celecoxib and placebo groups in one study (149 participants).

AUTHORS' CONCLUSIONS

Celecoxib may improve clinical symptoms, alleviate pain and contribute to little or no difference in physical function compared with placebo. Celecoxib was associated with fewer numbers of participant withdrawals. Results for incidence of gastroduodenal ulcers (≥ 3 mm) and short-term serious adverse events were uncertain; however, there were few reported events for either.Celecoxib may slightly improve clinical symptoms compared with tNSAIDs. Results for reduced pain and improved physical function were uncertain. Particpants taking celecoxib had lower incidence of gastroduodenal ulcers (≥ 3 mm) and there were fewer withdrawals from trials. Results for cardiovascular events and short-term serious adverse events were also uncertain.Uncertainty about the rate of cardiovascular events between celecoxib and tNSAIDs could be due to risk of bias; another factor is that these were small, short-term trials. It has been reported previously that both celecoxib and tNSAIDs increase cardiovascular event rates. Our confidence in results about harms is therefore low. Larger head-to-head clinical trials comparing celecoxib to other tNSAIDs is needed to better inform clinical practice.

Clinical characteristics of peptic ulcer perforation in Korea

AIM

To elucidate the epidemiological characteristics and associated risk factors of perforated peptic ulcer (PPU).

METHODS

We retrospectively reviewed medical records of patients who were diagnosed with benign PPU from 2010 through 2015 at 6 Hallym university-affiliated hospitals.

RESULTS

A total of 396 patients were identified with postoperative complication rate of 9.1% and mortality rate of 0.8%. Among 174 (43.9%) patients who were examined for Helicobacter pylori (H. pylori) infection, 78 (44.8%) patients were positive for H. pylori infection, 21 (12.1%) were on non-steroidal anti-inflammatory drugs (NSAIDs) therapy, and 80 (46%) patients were neither infected of H. pylori nor treated by any kinds of NSAIDs. Multivariate analysis indicated that older age (OR = 1.09, 95%CI: 1.04-1.16) and comorbidity (OR = 4.11, 95%CI: 1.03-16.48) were risk factors for NSAID-associated PPU compared with non-H. pylori, non-NSAID associated PPU and older age (OR = 1.04, 95%CI: 1.02-1.07) and alcohol consumption (OR = 2.08, 95%CI: 1.05-4.13) were risk factors for non-H. pylori, non-NSAID associated PPU compared with solely H. pylori positive PPU.

CONCLUSION

Elderly patients with comorbidities are associated with NSAIDs-associated PPU. Non-H. pylori, non-NSAID peptic ulcer is important etiology of PPU and alcohol consumption is associated risk factor.

Chronic disease and lifestyle factors associated with change in sleep duration among older adults in the Singapore Chinese Health Study

Identifying risk factors for future change in sleep duration can clarify whether, and if so how, sleep and morbidity are bidirectionally related. To date, only limited longitudinal evidence exists characterizing changes to sleep duration among older adults. This study aimed to identify factors associated with change in sleep duration in a large sample of older adults (≥ 60 years) residing in Singapore (n = 10 335). These adults were monitored as part of the Singapore Chinese Health Study, which collected information regarding daily sleep duration at baseline (assessed in 1993-1998) and at a follow-up wave conducted over a mean of 12.7 years later (assessed in 2006-2010). Among adults sleeping 6-8 h at baseline (n = 8265), most participants (55.6%) remained 6-8 h sleepers at follow-up, while 8.4% became short (< 6 h) and 36.0% became long (> 8 h) sleepers. A history of stroke, diabetes, cancer, hip fracture and greater age all independently increased the odds of having long sleep duration at follow-up, while greater educational attainment and weekly physical activity were both associated with reduced odds of becoming a long sleeper. Other than greater baseline age, the only factor related to higher odds of becoming a short sleeper was concurrent stomach/duodenal ulcer at follow-up. Long sleep duration among older adults may therefore reflect longstanding disease processes, whereas the aetiology of short sleep may predominately involve factors other than those examined. Future research is needed to distinguish if/when long sleep duration serves the disease recovery process, and when long sleep duration complicates disease and requires sleep medicine interventions.

[ULCER DAMAGE TO THE GASTROINTESTINAL PATH ASSOCIATED WITH HYPERTENSION AS A MANIFESTATION OF COMORBIDITY AMONG RAILWAY WORKERS]

PURPOSE OF THE STUDY

The investigation of clinical and laboratory parameters that characterize the pathogenetic connections of association of ulcerative lesions of the gastrointestinal tract and hypertension as work-related diseases among workers of locomotive brigades.

MATERIALS AND METHODS

192 railway workers were examined. The level of general clinical and biochemical parameters in the blood serum were investigated.

RESULTS

Due to the syntopy of duodenal ulcers and (or) the stomach and hypertension on the background of the negative impact of harmful factors of production the abnormalities in the vascular endothelium with signs of systemic inflammation are revealed.

CONCLUSION

The identified parameters can be considered as an early predictor of formation of hypertension as well as a comorbid flow of duodenal ulcers and (or) of the stomach and hypertension, assessing it as work-related diseases.

Analgesic, antiulcer, antithrombotic drugs and organ damage: a population-based case-control study

AIM

Oral medication is of paramount importance for pain treatment. Analgesics, antiulcer (AUDs) and antithrombotic drugs (ATDs) are often coprescribed in elderly people. Non-steroidal anti-inflammatory drugs (NSAIDs) require AUDs to lower the risk of peptic ulcer, and potentially interfere with ATDs. The aim of this study was to quantify the prevalence of NSAID use in patients with gastrointestinal, cardiac or kidney damage in the year 2013, compared to the general population.

METHODS

We performed a population-based case-control study in the Republic of San Marino to evaluate the Odds-Ratios for upper gastrointestinal damage (gastroduodenal ulcers and/or erosions, GUE), ischemic heart disease (IHD), heart failure (HF), and renal function impairment (assessed using the CKD-EPI formula), in people who had taken AUDs, ATDs, or NSAIDs in the previous 90 days, versus people who had not taken such drugs in the same period of time.

RESULTS

We found that AUDs decreased the OR for GUE (OR: 0.762; CI:0.598-0.972), while ATDs and NSAIDs increased the risk (OR: 1.238 and CI: 0.935-1.683; OR:1.203 and CI:0.909-1.592, respectively). NSAIDs seemed to increase the risk of IHD, although this was not statistically significant (OR=1.464; CI=0.592-3.621). AUDs and ATDs significantly increased the risk of renal function impairment (OR=1.369 and CI=1.187-1.579; OR=1.818 and CI=1.578-2.095, respectively), while this effect was not observed for NSAIDs.

CONCLUSION

NSAIDs may induce gastrointestinal and cardiovascular damage, not only by themselves, but also when used concomitantly with common medications such as AUDs or ATDs, due to additive and/or synergistic effects. We performed a "pragmatic" analysis of the association of organ damage with use of NSAIDs/AUDs/ATDs, including patient age, treatment duration and dose, to allow for an immediate application of our findings to everyday clinical practice.

Long-term effects of gastrectomy in patients with spirometry-defined COPD and patients at risk of COPD: a case-control study

OBJECTIVE

Comorbidities are characteristic of COPD. However, little is known about the secondary manifestations of COPD in the gastrointestinal tract. Therefore, we aimed to explore the long-term effects of gastrectomy in patients with spirometry-defined COPD or those at risk of COPD.

PARTICIPANTS

Subjects included 87 patients either with COPD or at risk of COPD (symptomatic) who underwent gastrectomy between December 2003 and October 2013 (group A), and 174 patients either with COPD or at risk of COPD, matched by age (±5 years), sex, and forced expiratory volume in 1 second (FEV1) as percentage of predicted (FEV1% predicted) (±5%) (group B).

METHODS

All patients underwent routine blood chemistry and pulmonary function tests, arterial blood gas analysis, 6-minute walk test (6MWT), high-resolution chest computed tomography scans, and nutritional assessments.

RESULTS

The mean duration postgastrectomy was 18.3±15.4 years. The mean FEV1 and FEV1% predicted were 2.07±0.76 L and 74.6±24.5%, respectively. Univariate analysis indicated that group A patients had significantly lower body mass index, fat-free mass index, and serum hemoglobin and albumin concentration (all P=0.00), and walked a significantly shorter distance in the 6MWT (P<0.05). Multivariate linear regression analysis for the distance in the 6MWT indicated that increased residual volume (RV) to total lung capacity (TLC) as percentage of predicted (%RV/TLC) alone was an independent and significant predictor of reduced distances in the 6MWT.

CONCLUSION

We concluded that nutritional insufficiency in patients with COPD (or those at risk of COPD) who previously underwent gastrectomy might lead to hyperinflation and consequently, decreased exercise capacity.

Upper gastrointestinal diseases in patients for endoscopy in South-Western Uganda

BACKGROUND

There is a paucity of published data regarding upper gastrointestinal diseases in Ugandans with upper gastrointestinal symptoms referred for endoscopy.

OBJECTIVES

To study the presenting complaints, pathology and Helicobacter pylori prevalence among patients with upper gastrointestinal symptoms in South-Western Uganda.

METHODS

Patients presenting with upper gastrointestinal symptoms underwent upper endoscopy and a urease test for Helicobacter Pylori, all suspicious lesions were biopsied for histopathology review as appropriate.

RESULTS

The most common presenting complaints were epigastric pain (51.6%), dysphagia (13.6%) and odynophagia (7.1%). The most common endoscopy finding was gastritis (40.2%), followed by normal examination (15.2%), oesophageal cancer (13.6%), gastric ulcer (7.6%) and gastric cancer (7.1%). Patients older than 40 years (n=110) had significant findings including gastritis (50.9%), oesophageal cancer (22.7%) and gastric cancer (11.8%). However in younger patients, with the age range of 18-40 years (n=74), most examinations were normal (92.9%). Of the 176 patients able to undergo Helicobacter pylori testing 75.6% were positive. Helicobacter pylori infection was associated with statistically significant increase in gastritis, oesophageal cancer, gastric ulcer, gastric cancer, and duodenal ulcers (p-values< 0.05).

CONCLUSION

Gastritis, ulcerative disease, and upper gastrointestinal malignancies are common in South-Western Ugandans and are associated with a high prevalence of Helicobacter pylori.

Reciprocal impact of host factors and Helicobacter pylori genotypes on gastric diseases

AIM: To assess the impact of Helicobacter pylori (H. pylori) genotypes and patient age and sex on the development of gastric diseases.

METHODS: H. pylori-infected patients (n = 233) referred to the endoscopy unit at Tehran University of Medical Sciences (Tehran, Iran) were diagnosed with chronic gastritis (CG), gastric ulcer (GU), or duodenal ulcer (DU). Brucella blood agar was used for biopsy cultures and H. pylori isolation under microaerobic conditions. H. pylori isolates were confirmed with biochemical tests and through amplification of the 16S rRNA gene. DNA was extracted from fresh cultures of the H. pylori isolates and used for amplification of vacA alleles and the cagA gene. Statistical analysis was performed to determine the association between H. pylori genotypes, age (< 40 years vs > 40 years) and sex of the patient, and gastric diseases.

RESULTS: CG was the most prevalent gastric disease (113/233; 48.5%), compared to GU (64/233; 27.5%) and DU (56/233; 24%). More patients were male, and gastric diseases were more frequent in patients > 40 years (P < 0.05). The percentage of CG and GU patients that were male and female did not show a significant difference; however DU was more common in males (P < 0.05). Interestingly, a diagnosis of CG in patients > 40 years was more common in females (18.5%) than males (11.6%) (P = 0.05), whereas a diagnosis of GU or DU in patients > 40 years was more frequent in males (14.6% vs 10.7% and 12.4% vs 4.3%, respectively). Overall, genotyping of the H. pylori isolates revealed that the vacA s1 (82%), vacA m2 (70%), and cagA⁺ (72.5%) alleles were more frequent than vacA s2 (18%), vacA m1 (29.2%), and cagA^- (all P < 0.05). The vacA s1m2cagA⁺ genotype was the most prevalent within the three disease groups. vacA s1m2 frequency was 56.2% with a similar occurrence in all diagnoses, while vacA s1m1 appeared more often in DU patients (33.9%). A genotype of vacA s2m2 occurred in 15% of isolates and was more common in CG patients (21.2%); vacA s2m1 was the least common genotype (3%). The vacA s1 allele was found to be a risk factor for DU, vacA s2 for CG, and vacA s1 and vacA s2 for GU (all P < 0.05). The vacA s2m2 genotype was associated with the development of CG and GU compared to DU (P < 0.05). No correlation was found between vacA m or cagA and gastric diseases.

CONCLUSION: The outcome of H. pylori infection is the result of interaction between bacterial genotypes and the age and sex of infected individuals.

Geographic differences in low-dose aspirin-associated gastroduodenal mucosal injury

Aspirin, even at low doses, has been known to cause upper gastro-intestinal complications, such as gastroduodenal ulcers, despite the definite benefits from its antithrombotic effects. Helicobacter pylori (H. pylori) is major pathogen responsible for gastroduodenal ulcer formation. There have been conflicting results about the potential interaction between these two ulcerogenic factors and the geographic areas involved. In Western countries, the prevalence of gastroduodenal ulcers is consistently higher in H. pylori-positive low-dose aspirin (LDA) users than in H. pylori-negative ones, suggesting that H. pylori infection exacerbates LDA-induced gastroduodenal mucosal injury in these geographic areas. Meanwhile, previous studies from Japan have generally reported a similar prevalence of LDA-induced gastroduodenal mucosal injury regardless of the presence of H. pylori infection, indicating that the infection is not an overall exacerbating factor for drug-induced injury. H. pylori infection could have a synergistic or antagonistic interaction with LDA use in adverse gastroduodenal events depending on gastric acid secretion. It is well-recognized that the net effect of H. pylori infection on gastric acid secretion shows considerable geographic variation at the population level. While gastric acid secretion levels were not decreased and were well-preserved in most patients with H. pylori infection from Western countries, the majority of Japanese patients with H. pylori infection exhibited decreased gastric acid secretion. Such large geographic differences in the net effect of H. pylori infection on gastric acid secretion could be at least partly responsible for the geographically distinct interaction between LDA use and H. pylori infection on adverse gastroduodenal lesions.

Predictive Factors for NSAIDs-related Gastrointestinal Toxicity: Can COX-2 Selective Inhibtor Prevent it?

BACKGROUND/AIMS

To identify predictive factors for NSAIDs-related GI toxicity and to clarify whether cox-2 selective inhibitors can prevent it or not.

METHODOLOGY

We have surveyed all patients received esophagogastroduodenoscopy examined at our hospital between January 2008 and September 2011. We performed the following retrospective analyses of the clinical records of the 253 patients prescribed NSAIDs. The severity of gastro duodenal mucosal lesions was evaluated using the modified gastro duodenal LANZA score. The following scores for response were used: 0 = no lesions (LANZA score 0); 1 = erosion and redness (LANZA score 1-3); 2 = ulcer (LANZA score 4). Predictors evaluated were factors potentially related to pathogenesis of NSAIDs related GI toxicity. Ordered logistic regression analysis was performed to identify predictive factors for NSAIDs related. ulcer.

RESULTS

A multivariate logistic regression identified number of risk factors (odds ratio (OR) = 6.82, confidence interval (CI) = 5.31-8.76; P = 0.01), concomitant use of anti- cancer drugs (OR = 2.17, Cl = 1.02-4.62; P = 0.04) were found to be significant factors.

CONCLUSIONS

Number of risk factors and concomitant use of anticancer drugs were shown to be predictive factors for NSAID-related GI toxicity. Use of celecoxib or proton pump inhibitor was not identified as a protective factor.

Characteristics of gastric cancer in peptic ulcer patients with Helicobacter pylori infection

AIM: To evaluate the incidence and clinical characteristics of gastric cancer (GC) in peptic ulcer patients with Helicobacter pylori (H. pylori) infection.

METHODS: Between January 2003 and December 2013, the medical records of patients diagnosed with GC were retrospectively reviewed. Those with previous gastric ulcer (GU) and H. pylori infection were assigned to the HpGU-GC group (n = 86) and those with previous duodenal ulcer (DU) disease and H. pylori infection were assigned to the HpDU-GC group (n = 35). The incidence rates of GC in the HpGU-GC and HpDU-GC groups were analyzed. Data on demographics (age, gender, peptic ulcer complications and cancer treatment), GC clinical characteristics [location, pathological diagnosis, differentiation, T stage, Lauren’s classification, atrophy of surrounding mucosa and intestinal metaplasia (IM)], outcome of eradication therapy for H. pylori infection, esophagogastroduodenoscopy number and the duration until GC onset were reviewed. Univariate and multivariate analyses were performed to identify factors influencing GC development. The relative risk of GC was evaluated using a Cox proportional hazards model.

RESULTS: The incidence rates of GC were 3.60% (86/2387) in the HpGU-GC group and 1.66% (35/2098) in the HpDU-GC group. The annual incidence was 0.41% in the HpGU-GC group and 0.11% in the HpDU-GC group. The rates of moderate-to-severe atrophy of the surrounding mucosa and IM were higher in the HpGU-GC group than in the HpDU-GC group (86% vs 34.3%, respectively, and 61.6% vs 14.3%, respectively, P < 0.05). In the univariate analysis, atrophy of surrounding mucosa, IM and eradication therapy for H. pylori infection were significantly associated with the development of GC (P < 0.05). There was no significant difference in the prognosis of GC patients between the HpGU-GC and HpDU-GC groups (P = 0.347). The relative risk of GC development in the HpGU-GC group compared to that of the HpDU-GC group, after correction for age and gender, was 1.71 (95%CI: 1.09-2.70; P = 0.02).

CONCLUSION: GU patients with H. pylori infection had higher GC incidence rates and relative risks. Atrophy of surrounding mucosa, IM and eradication therapy were associated with GC.

Prevalence of Helicobacter pylori infection and atrophic gastritis in patients with dyspeptic symptoms in Myanmar

AIM: To survey the detailed analyses for Helicobacter pylori (H. pylori) infection and gastric mucosal status in Myanmar.

METHODS: A total of 252 volunteers with dyspeptic symptoms (155 female and 97 male; mean age of 43.6 ± 14.2 years) was participated in Yangon and Mandalay. The status of H. pylori infection was determined based on 5 different tests including rapid urease test, culture, histology, immunohistochemistry and serology. Histological scores were evaluated according to the update Sydney system and the Operative Link for Gastritis Assessment system. Pepsinogen (PG) I and PG II were measured using enzyme-linked immunosorbent assays.

RESULTS: The overall prevalence of H. pylori infection was 48.0%. There was no relationship between age and infection rate. Even in young group (less than 29 years old), the H. pylori infection rate was relatively high (41.9%). The prevalence of H. pylori infection was significantly higher in Yangon than that of Mandalay. H. pylori infection was significantly associated with the presence of gastric mucosal atrophy. All 7 subjects with peptic ulcer were infected with H. pylori. Although H. pylori-positive subjects showed stronger gastritis than H. pylori-negative subjects, most cases had mild gastritis.

CONCLUSION: We revealed the prevalence of H. pylori infection in patients with dyspeptic symptoms in Myanmar. The H. pylori infection was a risk factor for peptic ulcer and stronger gastritis.

[STUDY OF THE VARIABILITY OF THE CARDIAC RHYTHM IN RAILROAD EMPLOYEES, WHO SUFFER BY STOMACH ULCER AND DUODENUM, ASSOCIATED AND NONASSOCIATED WITH THE INFECTION HELICOBACTER PYLORI]

AIM OF INVESTIGATION

To estimate the Heart rate variability (HRV), by the method of daily kholterovskogo monitoring in the workers of rail transport (RT).

MATERIALS AND METHODS

A total of 93 persons working in the East Siberian Railway. The main group (CG) consisted of 27 patients with gastric ulcer (GU) and duodenal ulcer (DU) contamination without Helicobacter infection. The first group of clinical comparison (GCS 1) included 36 patients with gastric ulcer and duodenal with contamination of infection H. pylori. The second group of clinical comparison (GCS 2) consisted of 30 employees VT held preventive medical examination, without contamination of Helicobacter infection is not suffering from gastric ulcer and duodenum.

RESULTS

With the analysis of spectral and time characteristics HRV in Haug is revealed the explicit displacement of vegetative homeostasis with the prevalence of the sympathetic component of regulation, which is restored against the background of treatment. Meanwhile in GKS1 the indices of vegetative regulation had parasympathetic directivity, they were more close to the standard and did not change after conducting of the eradikatsionnoy therapy.

CONCLUSION

The greatest unbalance of sympathetic and parasympathetic nervous system is observed in patients, workers (RT), who suffer SU and UD in the absence of the contamination of H. pylori. The use of a method of study VCR in the conditions of the absence of H. pylori infection can make it possible to form the group of risk of development SU and UD in workers RT.

Upper-gastrointestinal bleeding secondary to peptic ulcer disease: Incidence and outcomes

AIM: To evaluate the incidence, surgery, mortality, and readmission of upper gastrointestinal bleeding (UGIB) secondary to peptic ulcer disease (PUD).

METHODS: Administrative databases identified all hospitalizations for UGIB secondary to PUD in Alberta, Canada from 2004 to 2010 (n = 7079) using the International Classification of Diseases Codes (ICD-10). A subset of the data was validated using endoscopy reports. Positive predictive value and sensitivity with 95% confidence intervals (CI) were calculated. Incidence of UGIB secondary to PUD was calculated. Logistic regression was used to evaluate surgery, in-hospital mortality, and 30-d readmission to hospital with recurrent UGIB secondary to PUD. Co-variants accounted for in our logistic regression model included: age, sex, area of residence (i.e., urban vs rural), number of Charlson comorbidities, presence of perforated PUD, undergoing upper endoscopy, year of admission, and interventional radiological attempt at controlling bleeding. A subgroup analysis (n = 6356) compared outcomes of patients with gastric ulcers to those with duodenal ulcers. Adjusted estimates are presented as odds ratios (OR) with 95%CI.

RESULTS: The positive predictive value and sensitivity of ICD-10 coding for UGIB secondary to PUD were 85.2% (95%CI: 80.2%-90.2%) and 77.1% (95%CI: 69.1%-85.2%), respectively. The annual incidence between 2004 and 2010 ranged from 35.4 to 41.2 per 100000. Overall risk of surgery, in-hospital mortality, and 30-d readmission to hospital for UGIB secondary to PUD were 4.3%, 8.5%, and 4.7%, respectively. Interventional radiology to control bleeding was performed in 0.6% of patients and 76% of these patients avoided surgical intervention. Thirty-day readmission significantly increased from 3.1% in 2004 to 5.2% in 2010 (OR = 1.07; 95%CI: 1.01-1.14). Rural residents (OR rural vs urban: 2.35; 95%CI: 1.83-3.01) and older individuals (OR ≥ 65 vs < 65: 1.57; 95%CI: 1.21-2.04) were at higher odds of being readmitted to hospital. Patients with duodenal ulcers had higher odds of dying (OR = 1.27; 95%CI: 1.05-1.53), requiring surgery (OR = 1.73; 95%CI: 1.34-2.23), and being readmitted to hospital (OR = 1.54; 95%CI: 1.19-1.99) when compared to gastric ulcers.

CONCLUSION: UGIB secondary to PUD, particularly duodenal ulcers, was associated with significant morbidity and mortality. Early readmissions increased over time and occurred more commonly in rural areas.

Prevalence of lesions detected at upper endoscopy: an Italian survey

BACKGROUND

Prevalence of gastroduodenal lesions is changing in the last decades. Prevalence of Helicobacter pylori infection, non-steroidal anti-inflammatory drugs (NSAIDs), and proton pump inhibitor (PPI) therapy may be involved in such a phenomenon. We assessed gastroduodenal lesions prevalence in a nationwide study.

MATERIALS AND METHODS

Consecutive patients who underwent upper endoscopy for the first time in 24 Italian centres between January 2012 and 31 March 2012 were enrolled. Prevalence of gastric ulcer (GU), duodenal ulcer (DU), gastric erosions (GE), duodenal erosions (DE), gastric polyp (GP), Barrett's oesophagus (BE), and neoplasia was assessed.

RESULTS

Overall, 1054 (M/F: 388/666; Mean age: 57.5 ± 5 years) patients were enrolled. H. pylori infection was detected in 356 (33.9%) patients, 358 (34%) were taking NSAIDs, and 532 (50.5%) PPIs. PPI therapy was associated with a significantly lower H. pylori detection rate (27.8% vs 39.8%; OR: 0.6, 95% CI 0.45-0.77; P<0.001). GU, DU, GE, DE, GP and BE were detected in 17 (1.6%), 13 (1.2%), 150 (14.2%), 50 (4.7%), 51 (4.8%) and 17 (1.6%), respectively. Moreover, 3 (0.3%) distal gastric cancers were observed. H. pylori infection remained the most prevalent factor for all gastroduodenal lesions, but gastric polyp. One third of patients with GU and GE were taking only NSAIDs therapy.

CONCLUSIONS

The prevalence of peptic ulcer was very low (<3%), with a similar rate between DU and GU. As many as half patients were on ongoing PPI therapy. Such a therapy could affect both the detection rate of H. pylori infection and the real prevalence of gastroduodenal lesions.

History of Helicobacter pylori, duodenal ulcer, gastric ulcer and gastric cancer

Helicobacter pylori (H. pylori) infection underlies gastric ulcer disease, gastric cancer and duodenal ulcer disease. The disease expression reflects the pattern and extent of gastritis/gastric atrophy (i.e., duodenal ulcer with non-atrophic and gastric ulcer and gastric cancer with atrophic gastritis). Gastric and duodenal ulcers and gastric cancer have been known for thousands of years. Ulcers are generally non-fatal and until the 20^th century were difficult to diagnose. However, the presence and pattern of gastritis in past civilizations can be deduced based on the diseases present. It has been suggested that gastric ulcer and duodenal ulcer both arose or became more frequent in Europe in the 19^th century. Here, we show that gastric cancer and gastric ulcer were present throughout the 17^th to 19^th centuries consistent with atrophic gastritis being the predominant pattern, as it proved to be when it could be examined directly in the late 19^th century. The environment before the 20^th century favored acquisition of H. pylori infection and atrophic gastritis (e.g., poor sanitation and standards of living, seasonal diets poor in fresh fruits and vegetables, especially in winter, vitamin deficiencies, and frequent febrile infections in childhood). The latter part of the 19^th century saw improvements in standards of living, sanitation, and diets with a corresponding decrease in rate of development of atrophic gastritis allowing duodenal ulcers to become more prominent. In the early 20^th century physician’s believed they could diagnose ulcers clinically and that the diagnosis required hospitalization for “surgical disease” or for “Sippy” diets. We show that while H. pylori remained common and virulent in Europe and the United States, environmental changes resulted in changes of the pattern of gastritis producing a change in the manifestations of H. pylori infections and subsequently to a rapid decline in transmission and a rapid decline in all H. pylori-related diseases.

Peptic ulcer disease risk in chronic kidney disease: ten-year incidence, ulcer location, and ulcerogenic effect of medications

Objectives

We aimed at determining peptic ulcer disease (PUD) incidence among chronic kidney disease (CKD) patients during 1998–2008, compared to patients without CKD, and at examining associations between CKD and PUD.

Methods

Data for 1998–2008 were extracted from the National Health Insurance Research Database in Taiwan. The annual PUD incidence (cases per thousand persons per year) was calculated separately for patients with and without CKD. Characteristics of patients with newly diagnosed PUD (n = 16322) were compared to those of a control group without PUD (n = 32644). The 2 groups were matched for age, sex, and index year. Odds ratios (OR) and 95% confidence intervals (CI) were estimated by logistic regression.

Results

Over the 10-year period, the PUD incidence was ∼10–12 times higher in CKD patients than in those without CKD. Its incidence in elderly CKD patients increased rapidly over time. For CKD patients, most PUD events (>95%) were managed during hospitalization. Peptic ulcer risk, adjusted for all potential confounders, was much higher in CKD patients undergoing hemodialysis (adjusted OR, 9.74; 95% CI, 7.11–13.31). Maintenance hemodialysis patients were 2 times more likely to have gastric ulcers than duodenal ulcers, while CKD patients not on dialysis had similar risks for both. There were no significant interactions between medications and CKD status on the peptic ulcer risk. Unlike CKD patients on nonsteroidal anti-inflammatory drugs and clopidogrel, those on aspirin did not have a higher peptic ulcer risk (adjusted OR, 0.88; 95% CI, 0.44–1.77).

Conclusions

CKD patients have a substantially increased PUD risk, and the majority of CKD patients with PUD require hospital management. Further, peptic ulcer risk is affected by hemodialysis therapy, patient status (inpatient vs. outpatient), and ulcerogenic medications.

Population health concerns during the United States' Great Recession

BACKGROUND

Associations between economic conditions and health are usually derived from cost-intensive surveys that are intermittently collected with nonspecific measures (i.e., self-rated health).

PURPOSE

This study identified how precise health concerns changed during the U.S. Great Recession analyzing Google search queries to identify the concern by the query content and their prevalence by the query volume.

METHODS

Excess health concerns were estimated during the Great Recession (December 2008 through 2011) by comparing the cumulative difference between observed and expected (based on linear projections from pre-existing trends) query volume for hundreds of individual terms. As performed in 2013, the 100 queries with the greatest excess were ranked and then clustered into themes based on query content.

RESULTS

The specific queries with the greatest relative excess were stomach ulcer symptoms and headache symptoms, respectively, 228% (95% CI=35, 363) and 193% (95% CI=60, 275) greater than expected. Queries typically involved symptomology (i.e., gas symptoms) and diagnostics (i.e., heart monitor) naturally coalescing into themes. Among top themes, headache queries were 41% (95% CI=3, 148); hernia 37% (95% CI=16, 142); chest pain 35% (95% CI=6, 313); and arrhythmia 32% (95% CI=3, 149) greater than expected. Pain was common with back, gastric, joint, and tooth foci, with the latter 19% (95% CI=4, 46) higher. Among just the top 100, there were roughly 205 million excess health concern queries during the Great Recession.

CONCLUSIONS

Google queries indicate that the Great Recession coincided with substantial increases in health concerns, hinting at how population health specifically changed during that time.

Low-dose aspirin and comorbidities are significantly related to bleeding peptic ulcers in elderly patients compared with nonelderly patients in Japan

OBJECTIVE

The present study was conducted using data accumulated from our earlier study of bleeding peptic ulcers, focusing on elderly patients.

METHODS

A total of 461 patients with bleeding peptic ulcers underwent emergency endoscopy at Saga Medical School Hospital between 1999 and 2011. Risk factors for bleeding peptic ulcers were compared between two groups: an elderly group (≥65 years old) and a nonelderly group (<65 years old). The relationship between drug use and age was examined using multiple logistic regression models. In the elderly group, the factors were compared between Period I (1999-2005) and Period II (2006-2011).

RESULTS

The proportion of men and the incidence of Helicobacter pylori infection were lower in the elderly group than in the nonelderly group. The use of low-dose aspirin, antithrombotic drugs and corticosteroids, but not nonsteroidal anti-inflammatory drugs, was higher in the elderly group. A multiple logistic regression analysis of prescribed medications indicated that low-dose aspirin was more frequently used in the elderly group. The rate of comorbidities was higher and the hemoglobin levels were lower in the elderly group. The rates of rebleeding within one week and death within one month did not differ in the elderly group. Compared with that observed in Period I, the incidence of Helicobacter pylori infection was decreased and the rate of comorbidities was increased in Period II.

CONCLUSION

This study indicates that factors related to bleeding peptic ulcers in elderly patients have shifted from Helicobacter pylori infection to comorbidities associated with low-dose aspirin, suggesting a close relationship between low-dose aspirin therapy and comorbidities in elderly patients with peptic ulcers.

[Psychoemotional status and "adaptation diseases" at patients with the peptic ulcer in Ural Federal Territory]

RESEARCH OBJECTIVE

To study the psycho-emotional status and prevalence of the coronary heart disease (CHD) and the idiopathic hypertensia (IH) at patients with the peptic ulcer of a stomach (PUS) and at patients with a peptic ulcer of a duodenum is (YaB DPK).

MATERIALS AND METHODS

Examination of 226 patients with an exacerbation of a peptic ulcer was conducted. Patients were distributed in 3 groups of observation depending on localization of ulcerative process. At all surveyed questioning was carried out, data on heriditary burdeness, smoking, alcohol intake, existence of somatopathies were specified, clinic-morphological implications of a peptic ulcer were studied.

RESULTS

Feeling of alarm was present at 109 (48.2%) patients with a peptic ulcer, from them at 92 (40.7%) the subclinical level of alarm is noted, and at 17 (7.5%) clinically expressed form is taped. At 39.3% of the examined patients the depression is defined, from them two thirds of patients had the subclinical level of a depression, and 13 people suffered from clinically expressed depression form. Communication of recurrence with a stress was noted at 86.0% of patients, professionally caused stress--at 44.4%. In our research at the time of the beginning of a disease prevalence of an ischemic heart disease among patients with an ulcer of a duodenum (DPK) made 18.2%. In group of patients with the combined localization of ulcerative defect in a stomach and in DPK which already had an ischemic heart disease before emergence of the second ulcerative defect there were 26.6% that statistically significantly doesn't differ. However that by the time of emergence of the combined lesion this category of patients made already 73.4% is indicative. In case of DPK ulcer prevalence of an ischemic heart disease increased from the moment of the beginning of a disease until carrying out research twice (to 36.4%), but patients with the combined ultserozny lesion nevertheless distinguished both larger initial prevalence of an ischemic heart disease, and more expressed its gain. At the time of the beginning of a disease of GB met in a group of persons with the isolated ulcerative defect authentically more often (36.4% against 18.7% in group of patients with the combined localization of an ulcer). At the time of carrying out research prevalence of GB among patients with DPK ulcer (47.7%) whereas in group of the combined lesion of a stomach and DPK of GB without ischemic heart disease there was only every fourth patient remained significant by 2,7 times (DI 1.2-6.3). The combination of associated diseases of an ischemic heart disease and GB at patients with the advent of an ulcer at the same time in a stomach and DPK practically always met at the persons abusing alcohol and tobacco smoking that in general enlarges risk of development of an ulcer of the second localization by 7,6 times

CONCLUSION

At the peptic ulcer (PU) of any localization the previous stress conducting quite often to formation of alarm and a depression conducts to also education a stress--the induced conditions, for example, of an arterial hypertonia, and later--to an ischemic heart disease. As specific to every second patient with the combined form of a peptic ulcer of a stomach and a duodenum it is possible to consider a polisintropiya from such the comorbidity diseases as coronary heart disease and an idiopathic hypertensia. The combination of these associated diseases to alcohol intake and tobacco smoking progressively enlarges risk of development of a peptic ulcer of the combined localization by 7,6 times in comparison with the isolated duodenum canker.

RESEARCH OBJECTIVE

To define influence of the comorbidity diseases and risk.

Phlegmonous gastritis associated with group A streptococcal toxic shock syndrome

Phlegmonous gastritis (PG) is a rare, acute, severe infectious disease of the gastric wall that is often fatal due to Streptococcus spp. A 77-year-old man with diabetes and a gastric ulcer was urgently admitted due to prolonged nausea and vomiting. Computed tomography revealed widespread diffuse thickening of the gastric wall, and PG was suspected. The patient expired less than 9 hours after admission despite intensive treatments. Later, an analysis of the blood and gastric juice revealed group A streptococcus (GAS) and virulence factors associated with toxic shock syndrome (TSS). We herein diagnosed a patient with an extremely aggressive course of PG caused by GAS TSS.

Hemorrhagic gastric and duodenal ulcers after the Great East Japan Earthquake Disaster

AIM: To elucidate the characteristics of hemorrhagic gastric/duodenal ulcers in a post-earthquake period within one medical district.

METHODS: Hemorrhagic gastric/duodenal ulcers in the Iwate Prefectural Kamaishi Hospital during the 6-mo period after the Great East Japan Earthquake Disaster were reviewed retrospectively. The subjects were 27 patients who visited our hospital with a chief complaint of hematemesis or hemorrhagic stool and were diagnosed as having hemorrhagic gastric/duodenal ulcers by upper gastrointestinal endoscopy during a 6-mo period starting on March 11, 2011. This period was divided into two phases: the acute stress phase, comprising the first month after the earthquake disaster, and the chronic stress phase, from the second through the sixth month. The following items were analyzed according to these phases: age, sex, sites and number of ulcers, peptic ulcer history, status of Helicobacter pylori (H. pylori) infection, intake of non-steroidal anti-inflammatory drugs, and degree of impact of the earthquake disaster.

RESULTS: In the acute stress phase from 10 d to 1 mo after the disaster, the number of patients increased rapidly, with a nearly equal male-to-female ratio, and the rate of multiple ulcers was significantly higher than in the previous year (88.9% vs 25%, P < 0.005). In the chronic stress phase starting 1 mo after the earthquake disaster, the number of patients decreased to a level similar to that of the previous year. There were more male patients during this period, and many patients tended to have a solitary ulcer. All patients with duodenal ulcers found in the acute stress phase were negative for serum H. pylori antibodies, and this was significantly different from the previous year’s positive rate of 75% (P < 0.05).

CONCLUSION: Severe stress caused by an earthquake disaster may have affected the characteristics of hemorrhagic gastric/duodenal ulcers.

Prevalence of Helicobacter pylori virulence genotypes among children in Eastern Turkey

AIM: To identify the virulence genotypes of Helicobacter pylori (H. pylori) if present in children in Eastern Turkey and if those genotypes are mostly associated with severe clinical presentations.

METHODS: A total of 49 H. pylori positive Turkish children (42 with antral nodularity and 7 with peptic ulcer) who underwent upper gastrointestinal endoscopy with abdominal symptoms during the period from March 2011 to September 2012 were enrolled in this study. Antral nodularity was diagnosed endoscopically by two of the authors. We determined for the presence of cagA, vacA, cagE, iceA and babA2 genotypes of H. pylori isolates in DNA obtained directly from frozen gastric biopsy samples by polymerase chain reaction test using specific primers.

RESULTS: Of the 49 H. pylori isolates studied, 61.2%, 91.8%, 22.4%, 28.6%, 57.1% and 40.8% were positive for the cagA, vacA s1, cagE, iceA1, iceA2 and babA2 genes, respectively. We showed that the most common vacA subtype was s1a (79.6%). However, the s2 gene was found less frequently with an isolation rate of 8.2% of the H. pylori isolates. The genotypes iceA2 and vacA s1m2 were the most frequently found types in children with antral nodularity. In addition, the genotypes iceA1, babA2 and vacA s1m1 were found in similar ratios in all the H. pylori isolates obtained from children with peptic ulcer. The genotypes vacA s2m1 and s1c were not observed in any of isolates studied.

CONCLUSION: This study showed that vacA s1m2, cagA and iceA2 were the most common genotypes, and no association between antral nodularity and genotypes was observed.

[Helicobacter pylori population characteristic in patients with diseases of gastrointestinal tract]

AIM

Study H. pylori strains circulating in St. Petersburg among patients with various gastrointestinal tract pathology as well as study of frequency of infection by H. pylori based on serological markers data among this group of patients.

MATERIALS AND METHODS

By using serological method 162 individuals with various chronic diseases of stomach and duodenum were examined. The presence in blood serum of IgG against H. pylori bacterial antigen and IgG against its toxin--CagA was studied. 129 patients were examined bacteriologically, biopsy samples of stomach mucous membrane were studied. PCR in real time format was used for study of H. pylori strains (49) and biopsy samples (36) of stomach mucous membrane.

RESULTS

The analysis performed showed that on the territory of St. Petersburg H. pylori strains containing cagA gene predominate (81.63% of the isolated strains). Genotyping of strains by vacA showed that s1m1 genotype was more frequent (in 57.14% of cases). The fraction of CagA positive strains in patients in St. Petersburg is maximum for stomach cancer (90.8%), whereas for peptic ulcer disease and gastritis it is 64.7% and 72.2%, respectively. In patients with stomach and duodenum pathology the parameters of seropositivity for H. pylori were significantly higher than in individuals without clinical manifestations of H. pylori infection (86.72% against 65.09%; p < 0.05).

CONCLUSION

The data obtained on increase of fraction of CagA positive strains among H. pylori circulating in St. Petersburg determine the importance of conducting eradication H. pylori.

A discrete-choice experiment of United Kingdom patients' willingness to risk adverse events for improved function and pain control in osteoarthritis

OBJECTIVE

To assess patient preferences for treatment-related benefits and risks associated with the use of nonsteroidal anti-inflammatory drugs (NSAIDs) in the management of osteoarthritis (OA).

DESIGN

Using a chronic-illness panel in the United Kingdom, patients 45 years or older with a self-reported diagnosis of OA were eligible to participate in the study. Patient preferences were assessed using a discrete-choice experiment that compared hypothetical treatment profiles of benefits and risks consistent with NSAID use. Benefit outcomes (ambulatory pain, resting pain, stiffness, and difficulty doing daily activities) were presented on a 0-to-100 mm scale. Risk outcomes (bleeding ulcer, stroke, and myocardial infarction [MI]) were expressed as probabilities over a fixed time period. Each patient answered 10 choice tasks comparing different treatment profiles. Preference weights were estimated using a random-parameters logit model.

RESULTS

Final sample included 294 patients. Patients ranked reductions in ambulatory pain and difficulty doing daily activities (both: 6.32; 95% confidence interval [CI]: 5.0-7.6) as the most important benefit outcomes, followed by reductions in resting pain (2.80; 95% CI: 1.8-3.8) and stiffness (2.65; 95% CI: 0.9-4.4). Incremental changes (3%) in the risk of MI or stroke were assessed as the most important risk outcomes (10.00; 95% CI: 8.2-11.8; and 8.90; 95% CI: 7.3-10.5, respectively).

CONCLUSION

Patients ranked ambulatory pain as a more important benefit than resting pain; likely due to its impact on ability to do daily activities. For a 25-mm reduction, patients were willing to accept four times the risk of MI in ambulatory pain vs resting pain.

Stress: from symptom to disease

AIM

To evaluate the presence and role of stress in causing diseases.

MATERIALS AND METHODS

We conducted a 6-month study in patients who presented for the first time with a series of symptom and tried to look for an organic cause of those symptoms. We wanted to see the impact of stress in everyday life and its role in causing various diseases.

RESULTS

The obtained results showed a female predominance in terms of seeking medical advice and that the most affected age group was 20-30 years, accounted for by the start of socio-professional issues. The psycho-behavioural symptoms were the most prevalent, followed by the gastro-intestinal ones. The presence of stress had left its mark on these events, fact proven by the lower rate of organic pathology.

CONCLUSIONS

Stress awareness must guide us in medical practice as to avoid under- or over-diagnosis.

[Influence of the comorbidity diseases and risk factors on development of the combined peptic ulcer of the stomach and the duodenum]

RESEARCH OBJECTIVE

To define influence of the comorbidity diseases and risk factors of development of the combined peptic ulcer of a stomach and duodenum.

MATERIALS AND METHODS

As a result of carried-out poll and inspection 250 patients with an exacerbation of a peptic ulcer were surveyed. Patients were distributed in 3 groups of observation depending on localization of ulcerative process. At all surveyed questioning was carried out, data on hereditary load, smoking, alcohol intake, existence of somatopathies were specified, clinic-morphological implications of a peptic ulcer were studied.

RESULTS

The peptic ulcer of a stomach is characteristic for women (72.1%) and develops mainly aged from 45 till 59 years (60.3%). Peptic ulcer of duodenum men (76.3%) suffer mainly, the debut is the share in most cases of age from 18 to 44 years (79.1%). The combined canker of a stomach and duodenum meets at males (61.2%) more often, is initially involved in process ulcerogenesis by duodenum generally aged from 30 till 44 years (64.2%), accession of a canker of a stomach happens is delayed (at 38.8% within 16 and more years). In the analysis of risk factors at patients with the combined peptic ulcer of a stomach and duodenum depending on existence or absence specific to this category of patients of a background from such comorbidity diseases as IBS, HOBL and widespread osteochondrosis taped that larger prevalence of smoking (100%) and as the use (50%) and the excessive use (50%), alcohol are characteristic for the patients having a high comorbidity (a combination of three above nosologies).

CONCLUSION

The greatest interest in respect of possible communication with formation of the combined peptic ulcer of a stomach and duodenum is represented by IBS, HOBL and osteochondrosis. And major factors of risk were smoking, the excessive alcohol intake, the burdened heredity.

Effectiveness of thoracoscopic truncal vagotomy in the treatment of marginal ulcers after laparoscopic Roux-en-Y gastric bypass

Marginal ulcer is a significant complication of laparoscopic Roux-en-Y gastric bypass (LRYGB). Most marginal ulcers resolve with medical management, but nonhealing ulcers may require revision of the gastrojejunostomy, a procedure with significant morbidity and mortality. Traditionally, surgical therapy for refractory peptic ulcers includes a vagotomy. The current study evaluates the effectiveness of thoracoscopic truncal vagotomy (TTV) in the management of refractory marginal ulcers. All patients at two institutions with an intractable marginal ulcer after LRYGB treated with TTV between 2003 and 2010 were reviewed. Data were collected from chart review and telephone interview. Seventeen patients (mean age, 39 ± 13 years; 16 females) were diagnosed with marginal ulceration a median of 18 months after LRYGB and proceeded to TTV at a mean of 39 ± 43 weeks (range, 1 to 114 weeks) after the diagnosis. The median operative time was 89 ± 65 minutes (range, 45 to 318 minutes). Four patients had a complication (sympathetic contralateral pleural effusion, pneumothorax, operative bleeding, and readmission for emesis). Eleven patients had follow-up of 3 months to 6 years (median, 7 months). Nine patients (82%) had symptomatic improvement and/or endoscopic resolution, whereas two (18%) did not. No patient had endoscopic evidence of persistent or recurrent marginal ulcer. TTV achieves symptomatic improvement and/or endoscopic resolution of intractable marginal ulcers in over 80 per cent of patients status post gastric bypass and therefore offers a less morbid alternative to revision of the gastrojejunostomy.

Effects of Use of Alternative Therapies on Quality of Life and Healthcare Spending

Osteoarthritis (OA) is a costly disease that causes much morbidity and mortality in the world, and it was the sixth leading cause of disability in developed countries. We aim to study the utilization pattern of alternative therapies and their effects on quality of life and personal health spending in Chinese OA patients in Hong Kong. Five-hundred forty-seven patients with OA from four regional hospitals in Hong Kong were recruited, and we measured various types of alternative therapies, SF-36 scales, an overall Health Utility Index derived from a pre-scored multi-attribute classification system based upon SF-36 health surveys, health spending per person and out-of-pocket payments and side-effects. The study shows that out of the 547 OA patients, the patients have used a wide spectrum of alternative therapies and often used a multiplicity of them. Payment for alternative therapies constitutes 5% of the overall personal healthcare spending, and 29% of the out-of-pocket payments. The use of alternative therapies was significantly associated with higher personal healthcare spending ( p = 0.01), after adjusting for socioeconomic variables, years of OA and severity of OA. The use of alternative therapies was not significantly associated with an improvement in the quality of life in the regression analysis ( p = 0.64). The use of alternative therapies was statistically significant associated with the side effects, including gastric discomfort and gastric ulcer/bleeding ( p = 0.04, 0.02, respectively). Alternative therapies were used extensively by OA patients in Hong Kong. Clinicians, health policy makers, and insurance carriers should be aware of the potential health and economic effects in practice and policy formulation.

Perforated peptic ulcer disease in Zewditu Hospital

BACKGROUND

Peptic ulcer perforation is a serious complication of peptic ulcer disease with a significant morbidity and mortality.

OBJECTIVE

To evaluate 76 patients operated for peptic ulcer perforation and analyse the associated factors in Zewditu Memorial Hospital, Addis Ababa from September 2006 to August 2008.

PATIENTS AND METHODS

A retrospective analysis of medical records of 76 patients who were operated up on for perforated peptic ulcer over a two year period (2006-2008).

RESULTS

The male to female ratio was 6.6:1 with a mean age being 31.5 years. The most common presenting symptom was abdominal pain in 76 (100%) patients. History of smoking and khat chewing was documented in 53/64 (82.8%) and 48/64 (75%) of the patients respectively. Twenty five per cent of the patients gave no history of previous peptic ulcer disease. Seventy patients (92.1%) presented after 48 hours of their illness. The mean hospital stay was 14.5 days. Leucocytosis was found in 31.6% of the cases. Sixty five (85.5%) patients had duodenal ulcer perforation. Postoperative complications occurred in 24 (31.6%) patients. Twelve (15.8%) patients died in the hospital.

CONCLUSION

Early presentation of patients and change in life style may reduce morbidity and mortality in patients with peptic ulcer perforation.

Upper gastrointestinal haemorrhage and deprivation: a nationwide cohort study of health inequality in hospital admissions

OBJECTIVE

Inequalities in health are well recognized in cardiovascular disease and cancer, but in comparison, we have minimal understanding for upper gastrointestinal bleeding. Since furthering our understanding of such inequality signposts preventable disease, we investigated in detail the association between upper gastrointestinal bleeding and socioeconomic status.

DESIGN

Population-based cohort study.

SETTING

All English National Health Service hospitals.

POPULATION

English adult population, 1 January 2001 to 31 December 2007.

EXPOSURE MEASURES

Deprivation scores defined according to quintiles of neighbourhood areas ranked by the Indices of Multiple Deprivation for England 2007.

OUTCOME MEASURES

Rates of all adult admissions coded with a primary diagnosis of upper gastrointestinal bleed were analysed by deprivation quintile and adjusted for age, sex, region and year using Poisson regression.

RESULTS

The annual hospitalization rate for non-variceal haemorrhage was 84.6 per 100,000 population (95% CI 83.5 to 84.1; n=237,145), and for variceal haemorrhage, it was 2.83 per 100,000 population (95% CI 2.87 to 2.99; n=8291). There was a twofold increase in the hospitalization rate ratio for non-variceal haemorrhage from the most deprived areas compared to the least deprived (2.00, 95% CI 1.98 to 2.03). The ratio for variceal haemorrhage was even more pronounced (2.49, 95% CI 2.32 to 2.67). Inequality increased over the study period (non-variceal p<0.0001, variceal p=0.0068), and adjusting for age and sex increased the disparity between deprived and affluent areas. Case fatality did not have a similar socioeconomic gradient.

CONCLUSION

Both variceal and non-variceal haemorrhage hospitalization rates increased with deprivation, and there was a similar gradient in all areas of the country and in all age bands. The existence of such a steep gradient suggests that there are opportunities to reduce hospitalizations down to the low rates seen in the most affluent, and thus, there is the potential to prevent almost 10,000 admissions and over 1000 deaths a year.
