Complicated and uncomplicated peptic ulcers in a Danish county 1993-2002: a population-based cohort study

Frailty, Treatments, and Outcomes in Older Patients With Myocardial Infarction: A Nationwide Registry-Based Study

Background Guidelines recommend that patients with myocardial infarction (MI) receive equal care regardless of age. However, withholding treatment may be justified in elderly and frail patients. This study aimed to investigate trends in treatments and outcomes of older patients with MI according to frailty. Methods and Results All patients aged ≥75 years with first-time MI during 2002 to 2021 were identified through Danish nationwide registries. Frailty was categorized using the Hospital Frailty Risk Score. One-year risk and hazard ratios (HRs) for days 0 to 28 and 29 to 365 were calculated for all-cause death. A total of 51 022 patients with MI were included (median, 82 years; 50.2% women). Intermediate/high frailty increased from 26.7% in 2002 to 2006 to 37.1% in 2017 to 2021. Use of treatment increased substantially regardless of frailty: for example, 28.1% to 48.0% (statins), 21.8% to 33.7% (dual antiplatelet therapy), and 7.6% to 28.0% (percutaneous coronary intervention) for high frailty (all P-trend <0.001). One-year death decreased for low frailty (35.1%-17.9%), intermediate frailty (49.8%-31.0%), and high frailty (62.8%-45.6%), all P-trend <0.001. Age- and sex-adjusted 29- to 365-day HRs (2017-2021 versus 2002-2006) were 0.53 (0.48-0.59), 0.62 (0.55-0.70), and 0.62 (0.46-0.83) for low, intermediate, and high frailty, respectively (P-interaction=0.23). When additionally adjusted for treatment, HRs attenuated to 0.74 (0.67-0.83), 0.83 (0.74-0.94), and 0.78 (0.58-1.05), respectively, indicating that increased use of treatment may account partially for the observed improvements. Conclusions Use of guideline-based treatments and outcomes improved concomitantly in older patients with MI, irrespective of frailty. These results indicate that guideline-based management of MI may be reasonable in the elderly and frail.

Long-term mortality, cardiovascular events, and bleeding in stable patients 1 year after myocardial infarction: a Danish nationwide study

AIMS

Outcomes after myocardial infarction (MI) improved during recent decades alongside better risk factor management and implementation of guideline-recommended treatments. However, it is unknown whether this applies to stable patients who are event-free 1 year after MI.

METHODS AND RESULTS

Using nationwide Danish registries, we included all patients with first-time MI during 2000-17 who survived 1 year free from bleeding and cardiovascular events (n = 82 108, median age 64 years, 68.2% male). Follow-up started 1 year after MI and continued through January 2022. Crude risks of mortality, cardiovascular events, and bleeding were estimated in consecutive 3-year periods. Standardized risks were calculated with respect to the distribution of age, sex, comorbidities, and treatments in the latter period. Guideline-recommended treatment use increased during the study period: e.g. statins (68.6-92.5%) and percutaneous coronary intervention (23.9-68.2%). The crude 5-year risks of outcomes decreased (all P-trend <0.001): Mortality, 18.6% (95% confidence interval [CI]: 17.9-19.2) to 12.5% (CI: 11.9-13.1); Recurrent MI, 7.5% (CI: 7.1-8.0) to 5.5% (CI: 5.1-6.0); Bleeding, 3.9% (CI: 3.6-4.3) to 2.7% (CI: 2.4-3.0). Crude 5-year risk of mortality in 2015-17 was as low as 2.6% for patients aged <60 years. Use of guideline-recommended treatments was associated with improved outcomes: After standardization for changes in treatments, 5-year risk of mortality in 2000-02 was 15.5% (CI: 14.9-16.2).

CONCLUSIONS

For patients who were event-free 1 year after MI, the long-term risks of mortality, cardiovascular events, and bleeding decreased significantly, along with an improved use of guideline-recommended treatments between 2000 and 2017. In the most recent period, 1 year after MI, the risk of additional events was lower than previously reported.

The contribution of general medical conditions to the non-fatal burden of mental disorders: register-based cohort study in Denmark

BACKGROUND

General medical conditions (GMCs) often co-occur with mental and substance use disorders (MSDs).

AIMS

To explore the contribution of GMCs to the burden of disease in people with MSDs, and investigate how this varied by age.

METHOD

A population-based cohort of 6 988 507 persons living in Denmark during 2000-2015 followed for up to 16 years. Danish health registers were used to identify people with MSDs and GMCs. For each MSD, years lived with disability and health loss proportion (HeLP) were estimated for comorbid MSDs and GMCs, using a multiplicative model for disability weights.

RESULTS

Those with any MSD lost the equivalent of 43% of healthy life (HeLP = 0.43, 95% CI 0.40-0.44) after including information on GMCs, which was an increase from 25% before including GMCs (HeLP = 0.25, 95% CI 0.23-0.27). Schizophrenia was associated with the highest burden of disease (HeLP = 0.77, 95% CI 0.68-0.85). However, within each disorder, the relative contribution of MSDs and GMCs varied. For example, in those diagnosed with schizophrenia, MSDs and GMCs accounted for 86% and 14% of the total health loss; in contrast, in those with anxiety disorders, the same proportions were 59% and 41%. In general, HeLP increased with age, and was mainly associated with increasing rates of pulmonary, musculoskeletal and circulatory diseases.

CONCLUSIONS

In those with mental disorders, the relative contribution of comorbid GMCs to the non-fatal burden of disease increases with age. GMCs contribute substantially to the non-fatal burden of disease in those with MSDs.

Strongly increased risk of gastric and duodenal ulcers among new users of low-dose aspirin: results from two large cohorts with new-user design

BACKGROUND

Low-dose aspirin is a risk factor for peptic ulcer disease but previous, population-based cohort studies may have underestimated the low-dose aspirin risk because they did not use a new-user design. Gastrointestinal bleeding occurs more frequently early after initiation of low-dose aspirin therapy than in later years.

AIM

To assess the associations of low-dose aspirin with gastric and duodenal ulcer incidence in prevalent- and new-user design.

METHODS

Multivariate Cox regression models in the German ESTHER study (N = 7737) and the UK Biobank (N = 213,598) with more than 10 years of follow-up.

RESULTS

In the prevalent-user design, there was no significant association between low-dose aspirin and gastric ulcer observed in both cohorts. Furthermore, low-dose aspirin was weakly, statistically significantly associated with prevalent duodenal ulcer in the UK Biobank (hazard ratio [95% confidence interval]: 1.27 [1.07-1.51]) but not in the ESTHER study (1.33 [0.54-3.29]). When restricting the exposure to only new users, the hazard ratios for incident gastric and duodenal ulcer disease were 1.82 [1.58-2.11] and 1.66 [1.36-2.04] in the UK Biobank, respectively, and 2.83 [1.40-5.71] and 3.89 [1.46-10.42] in the ESTHER study, respectively.

CONCLUSIONS

This study shows that low-dose aspirin is an independent risk factor for both gastric and duodenal ulcers. The associations were not significant or weak in the prevalent-user design and strong and statistically significant in the new-user design in both cohorts. Thus, it is important to weigh risks against benefits when low-dose aspirin treatment shall be initiated and to monitor adverse gastrointestinal symptoms after the start of low-dose aspirin therapy.

Association of inferior vena cava diameter ratio with outcomes in patients with gastrointestinal bleeding

Objective

To examine the association of inferior vena cava (IVC) diameter ratio measured using computed tomography with outcomes in patients with gastrointestinal bleeding (GIB).

Methods

A single-center retrospective observational study was conducted on consecutive patients with GIB who presented to the emergency department. The IVC diameter ratio was calculated by dividing the maximum transverse and anteroposterior diameters perpendicular to it. The association of the IVC diameter ratio with outcomes was examined using multivariable logistic regression analysis. The primary outcome was in-hospital mortality. The area under the receiver operator characteristic curve (AUC) of the IVC diameter ratio was calculated, and the sensitivity and specificity, including the cutoff values, were computed.

Results

In total, 585 patients were included in the final analysis. The in-hospital mortality rate was 4.6% (n=27). The IVC diameter ratio was significantly associated with higher in-hospital mortality in multivariable logistic regression analysis (odds ratio, 1.793; 95% confidence interval [CI], 1.239–2.597; P=0.002). The AUC of the IVC diameter ratio for in-hospital mortality was 0.616 (95% CI, 0.498–0.735). With a cutoff of the IVC diameter ratio (≥2.1), the sensitivity and specificity for predicting in-hospital mortality were 44% (95% CI, 26%–65%) and 71% (95% CI, 67%–75%), respectively.

Conclusion

The IVC diameter ratio was independently associated with in-hospital mortality in patients with GIB. However, the AUC of the IVC diameter ratio for in-hospital mortality was low.

Low serum albumin may predict poor efficacy in patients with perforated peptic ulcer treated nonoperatively

BACKGROUND

Nonoperative management (NOM) is a promising therapeutic modality for patients with perforated peptic ulcer (PPU). However, the risk factors for poor efficacy and adverse events of NOM are a concern.

AIM

To investigate the factors predictive of poor efficacy and adverse events in patients with PPU treated by NOM.

METHODS

This retrospective case-control study enrolled 272 patients who were diagnosed with PPU and initially managed nonoperatively from January 2014 to December 2018. Of these 272 patients, 50 converted to emergency surgery due to a lack of improvement (surgical group) and 222 patients were included in the NOM group. The clinical data of these patients were collected. Baseline patient characteristics and adverse outcomes were compared between the two groups. Logistic regression analysis and receiver operating characteristic curve analyses were conducted to investigate the factors predictive of poor efficacy of NOM and adverse outcomes in patients with PPU.

RESULTS

Adverse outcomes were observed in 71 patients (32.0%). Multivariate analyses revealed that low serum albumin level was an independent predictor for poor efficacy of NOM and adverse outcomes in patients with PPU.

CONCLUSION

Low serum albumin level may be used as an indicator to help predict the poor efficacy of NOM and adverse outcomes, and can be used for risk stratification in patients with PPU.

Comparing the Performance of the ABC, AIMS65, GBS, and pRS Scores in Predicting 90-day Mortality Or Rebleeding Among Emergency Department Patients with Acute Upper Gastrointestinal Bleeding: A Prospective Multicenter Study

Background and Objectives

Acute upper gastrointestinal bleeding (UGIB) is a common problem that can cause significant morbidity and mortality. We aimed to compare the performance of the ABC score (ABC), the AIMS65 score (AIMS65), the Glasgow-Blatchford score (GBS), and the pre-endoscopic Rockall score (pRS) in predicting 90-day mortality or rebleeding among patients with acute UGIB.

Methods

This was a prospective multicenter study conducted at 20 tertiary hospitals in China. Data were collected between June 30, 2020 and February 10, 2021. An area under the receiver operating characteristic curve (AUC) analysis was used to compare the performance of the four scores in predicting 90-day mortality or rebleeding.

Results

Among the 1072 patients included during the study period, the overall 90-day mortality rate was 10.91% (117/1072) and the rebleeding rate was 12.03% (129/1072). In predicting 90-day mortality, the ABC and pRS scores performed better with an AUC of 0.722 (95% CI 0.675-0.768; P<0.001) and 0.711 (95% CI 0.663-0.757; P<0.001), respectively, compared to the AIMS-65 (AUC, 0.672; 95% CI, 0.624-0.721; P<0.001) and GBS (AUC, 0.624; 95% CI, 0.569-0.679; P<0.001) scores. In predicting rebleeding in 90 days, the AUC of all scores did not exceed 0.70.

Conclusion

In patients with acute UGIB, ABC and pRS performed better than AIMS-65 and GBS in predicting 90-day mortality. The performance of each score is not satisfactory in predicting rebleeding, however. Newer predictive models are needed to predict rebleeding after UGIB.

A Nationwide Cohort Study Shows a Sex-Dependent Change in the Trend of Peptic Ulcer Bleeding Incidence in Korea between 2006 and 2015

Background/Aims

The incidence of peptic ulcer disease has decreased in past decades; however, the trends in peptic ulcer bleeding (PUB) are inconsistent among regions. This study aimed to investigate the trends in PUB incidence and the effect of risk factors on PUB in Korea.

Methods

The records of patients hospitalized with PUB from 2006 to 2015 were retrieved from the Korean National Health Insurance Service Database. Standardized incidences of PUB were calculated, and the clinical characteristics such as age, sex, Helicobacterpylori infection, drug exposure, comorbidities, and mortality were obtained.

Results

In total, 151,507 hospitalizations with PUB were identified. The overall annual hospitalization rate was 34.98 per 100,000 person-years. The incidence of PUB showed no significant change from 2006 to 2008 and decreased from 2008 to 2015, with an annual change of –2.7% (p<0.05); however, this change was only significant in men. The incidence of PUB was higher in men than in women between 40 and 70 years old and higher in women than in men older than 80 years. From 2006 to 2015, the H. pylori infection rate increased significantly in patients with PUB; however, there was no significant change in exposure to nonsteroidal anti-inflammatory drugs or other drugs that increase the risk of PUB.

Conclusions

Over the past decade, the incidence of PUB has decreased in a sex-specific manner. There has been a decreasing trend in the H. pylori infection rate and no change in exposure to drugs that increase the risk of PUB in Korea.

Study on the preventive effect of intravenous esomeprazole in the management of nonvarices upper gastrointestinal bleeding

This retrospective study investigated the preventive effect of intravenous esomeprazole (IVEO) in the prevention of nonvarices upper gastrointestinal bleeding (NUGIB).This study enrolled 130 patients with NUGIB and all of them underwent successful endoscopic hemostasis, of which 65 cases received routine management and IVEO (Group A) and the other 65 cases received routine management alone (Group B). The primary outcome (recurrent bleeding rate within 72-hour, 7-day, and 30-day), and secondary outcomes ((all-cause mortality, bleeding-related mortality, blood transfused, hospital stay (day), and incidence of adverse events)) were compared between 2 groups.Patients in the group A showed lower recurrent bleeding rate within 72-hour(P < .05), 7-day (P < .05), and 30-day (P < .05), than that of patients in the group B. However, no significant differences were identified in all-cause mortality(P = .26), bleeding-related mortality (P = .57), blood transfused (P = .33), and hospital stay (P = .74) between 2 groups. In addition, both groups had similar safety profile.This study found that routine management and IVEO was superior to the routine management alone for preventing the recurrent bleeding rate after successful endoscopic hemostasis in patients with NUGIB.

Urban-Rural Disparities and Temporal Trends in Peptic Ulcer Disease Epidemiology, Treatment, and Outcomes in the United States

INTRODUCTION

The incidence of peptic ulcer disease (PUD) has been decreasing over time with Helicobacter pylori eradication and use of acid-suppressing therapies. However, PUD remains a common cause of hospitalization in the United States. We aimed to evaluate contemporary national trends in the incidence, treatment patterns, and outcomes for PUD-related hospitalizations and compare care delivery by hospital rurality.

METHODS

Data from the National Inpatient Sample were used to estimate weighted annual rates of PUD-related hospitalizations. Temporal trends were evaluated by joinpoint regression and expressed as annual percent change with 95% confidence intervals (CIs). We determined the proportion of hospitalizations requiring endoscopic and surgical interventions, stratified by clinical presentation and rurality. Multivariable logistic regression was used to assess independent predictors of in-hospital mortality and postoperative morbidity.

RESULTS

There was a 25.8% reduction (P < 0.001) in PUD-related hospitalizations from 2005 to 2014, although the rate of decline decreased from -7.2% per year (95% CI: 13.2% to -0.7%) before 2008 to -2.1% per year (95% CI: 3.0% to -1.1%) after 2008. In-hospital mortality was 2.4% (95% CI: 2.4%-2.5%). Upper endoscopy (84.3% vs 78.4%, P < 0.001) and endoscopic hemostasis (26.1% vs 16.8%, P < 0.001) were more likely to be performed in urban hospitals, whereas surgery was performed less frequently (9.7% vs 10.5%, P < 0.001). In multivariable logistic regression, patients managed in urban hospitals were at higher risk for postoperative morbidity (odds ratio 1.16 [95% CI: 1.04-1.29]), but not death (odds ratio 1.11 [95% CI: 1.00-1.23]).

DISCUSSION

The rate of decline in hospitalization rates for PUD has stabilized over time, although there remains significant heterogeneity in treatment patterns by hospital rurality.

Pre-endoscopic intravenous proton pump inhibitors therapy for upper gastrointestinal bleeding: A prospective, multicentre study

BACKGROUND/AIM

The indiscriminate use of high-dose, proton pump inhibitor (PPI) infusion in non-variceal upper gastrointestinal bleeding (UGIB) patients to reduce the rate of peptic ulcers with high-risk stigmata (HRS) has been questioned. We evaluated the prevalence of HRS on peptic ulcer and non-ulcer lesions in patients receiving or not receiving pre-endoscopic PPI therapy.

METHODS

Data of consecutive UGIB patients observed in 50 Italian centres were analysed. The prevalence of both HRS on peptic ulcers and active bleeding on non-ulcer lesions between patients treated or not treated with PPI were compared. Multivariate analysis was performed.

RESULTS

A total of 1,792 (69.8%) out of 2,566 patients received PPI therapy. Prevalence of HRS on ulcers was 51.8% and 53.4% (P = 0.58) in treated and not treated patients, respectively, and the rate of endoscopic therapy did not differ between groups. Prevalence of non-ulcer bleeding lesions was higher in patients treated than in those not treated with PPI (18.7% vs 10.6%; P = 0.023). At multivariate analysis, PPI therapy (OR: 1.16, 95% CI = 0.82-1.64; P = 0.4) was not an independent factor affecting HRS prevalence, which was inversely correlated with timing to endoscopy (OR: 0.85, 95% CI = 0.76-0.95; P = 0.005).

CONCLUSIONS

Our data failed to detect a significant role of pre-endoscopic PPI therapy in decreasing prevalence of HRS and need for endoscopic treatment in bleeding patients with either peptic ulcer or non-ulcer lesions.

Reduced risk of gastrointestinal bleeding associated with proton pump inhibitor therapy in patients treated with dual antiplatelet therapy after myocardial infarction

AIMS

Guidelines differ in their recommendations on therapy to prevent gastrointestinal bleeding for patients treated with dual antiplatelet treatment (DAPT). We sought to investigate the effectiveness of proton pump inhibitors (PPIs) to prevent upper gastrointestinal (UGI) bleeding in patients using DAPT following myocardial infarction (MI) in relation to current European Society of Cardiology guidelines recommendations.

METHODS AND RESULTS

We linked Danish nationwide registries to identify patients taking DAPT 7 days following hospital discharge for an acute MI, and excluded individuals on anticoagulation therapy. We used multiple Cox regression modelling, to compute average risk of UGI bleeding in relation to PPI use. The associated treatment efficacy was compared based on guideline risk assessment. We studied 46 301 patients on DAPT after MI. Only 35% of patients at higher risk of UGI bleeding received recommended treatment with a PPI based on the guideline criteria. The 1--year risk of UGI bleeding was 1.0% [95% confidence interval (CI) 0.9-1.1%] and 1.7% (CI 1.5-2.0%) for high-risk patients. Overall PPI compared with no therapy, was associated with a risk ratio for UGI bleeding of 0.62 (CI 0.48-0.77) corresponding to an absolute risk difference of 0.44% (CI 0.39-0.48%). Proton pump inhibitor therapy was associated with a similar absolute risk difference [0.47% (CI 0.43-0.51%)] for high-risk patients.

CONCLUSION

Proton pump inhibitor therapy is used less than suggested by guidelines in patients treated with DAPT following MI and was generally associated with reduced risk of UGI bleeding. Considering the overall low risk of bleeding, more focus should be on identifying patients benefiting the most from PPI therapy.

Gastrointestinal bleeding due to peptic ulcers and erosions - a prospective observational study (BLUE study)

OBJECTIVES

Acute upper gastrointestinal bleeding is a well-recognized complication of peptic ulcers and erosions. The aim of this study was to assess the incidence rate and identify risk factors for this complication in southeastern Norway.

MATERIALS AND METHODS

Between March 2015 and December 2017, a prospective observational study was conducted at two Norwegian hospitals with a total catchment area of approximately 800,000 inhabitants. Information regarding patient characteristics, comorbidities, drug use, H. pylori status and 30-day mortality was recorded.

RESULTS

A total of 543 adult patients were included. The incidence was 30/100,000 inhabitants per year. Altogether, 434 (80%) of the study patients used risk medication. Only 46 patients (8.5%) used proton pump inhibitors (PPIs) for more than 2 weeks before the bleeding episode. H. pylori testing was performed in 527 (97%) patients, of whom 195 (37%) were H. pylori-positive. The main comorbidity was cardiovascular disease. Gastric and duodenal ulcers were found in 183 (34%) and 275 (51%) patients, respectively. Simultaneous ulcerations at both locations were present in 58 (10%) patients, and 27 (5%) had only erosions. Overall, the 30-day mortality rate was 7.6%.

CONCLUSIONS

The incidence of upper gastrointestinal bleeding due to peptic ulcers and erosions was found to be lower than previously demonstrated in comparable studies, but the overall mortality rate was unchanged. The consumption of risk medication was high, and only a few patients had used prophylactic PPIs. Concurrent H. pylori infection was present in only one-third of the patients.

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.

In-hospital acute upper gastrointestinal bleeding: What is the scope of the problem?

BACKGROUND

Acute upper gastrointestinal bleeding (AUGIB) is a frequently encountered condition in the Gastroenterology field with a mortality rate of 10-14%. Despite recent newer innovations and advancements in endoscopic techniques and available medications, the mortality rate associated with AUGIB remained persistently elevated.

AIM

To explore mortality, characteristics and outcome differences between hospitalized patients who develop AUGIB while in-hospital, and patients who initially present with AUGIB.

METHODS

This is a retrospective of patients who presented to Northwell Health Staten Island University Hospital from October 2012 to October 2016 with AUGIB that was confirmed endoscopically. Patients were divided in two groups: Group 1 comprised patients who developed AUGIB during their hospital stay; group 2 consisted of patients who initially presented with AUGIB as their main complaint. Patient characteristics, time to endoscopy, endoscopy findings and interventions, and clinical outcomes were collected and compared between groups.

RESULTS

A total of 336 patients were included. Group 1 consisted of 139 patients and group 2 of 196 patients. Mortality was significantly higher in the 1st group compared to the 2nd (20% vs 3.1%, P ≤ 0.05). Increased length of stay (LOS) was noted in the 1st group (13 vs 6, P ≤ 0.05). LOS post-endoscopy, vasopressor use, number of packed red blood cell units and patients requiring fresh frozen plasma were higher in group 1. Inpatients were more likely to be on corticosteroids, antiplatelets and anticoagulants. Conversely, the mean time from bleeding to undergoing upper endoscopy was significantly lower in group 1 compared to group 2.

CONCLUSION

In-hospital AUGIB is associated with high mortality and morbidity despite a shorter time to endoscopy. Larger scale studies assessing the role of increased comorbidities and antithrombotic use in this setting are warranted.

The Effect of Hemostasis Powder® on Treatment of Bleeding from Benign Ulcers of Upper Gastrointestinal Tract; A Pilot Study

BACKGROUND

Gastrointestinal (GI) bleeding is one of the most prevalent internal medical emergencies. Despite using several methods of treatment, effective treatment cannot be achieved in some patients. Hemostasis powder® is a mineral-herbal product. This emulsion was able to coagulate blood in, in vitro studies and also was effective in the treatment of mucosal and cutaneous bleeding in animal studies, without any toxicity. We decided to compare its effect on the treatment of human GI bleeding with the other common method for treatment of GI bleeding "argon plasma coagulation plus epinephrine injection" in a pilot randomized clinical trial.

METHODS

The patients with GI bleeding who were admitted to the emergency wards of Ghaem and Imam-Reza Hospitals in Mashhad were randomized to treatment with Hemostasis powder® or "argon plasma coagulation plus epinephrine injection" method, with randomized doctors, after complete testimonial sheet. The patients underwent re-endoscopy to evaluate the ulcers 3 days later, and were under observation for 3 months. After achieving the number of patients that was planned (20 patients), all data were entered to SPSS software version 20 and were analyzed with parametric and non-parametric tests.

RESULTS

The treatment success was 95% in both groups. There was no complication after treatment of GI bleeding in the two groups after 3 months. No rebreeding was reported in Hemostasis powder® group but 10 % was reported in "argon plasma coagulation plus epinephrine injection" group.

CONCLUSION

It seems that if the successful results occur in the future complimentary studies, Hemostasis powder® can be used as a new, effective, available, and inexpensive measure in the treatment of GI bleeding and also in the GI bleedings that cannot be treated with common available methods.

Risk of thromboembolic and bleeding outcomes following hematological cancers: A Danish population-based cohort study

BACKGROUND

Therapeutic advances have improved survival after hematological cancers. In turn, patients may be at increased risk of thromboembolic and bleeding events.

OBJECTIVES

To examine the risks of myocardial infarction (MI), ischemic stroke, venous thromboembolism (VTE), and bleeding requiring hospital contact in patients with hematological cancers.

METHODS

We conducted a Danish population-based cohort study (2000-2013). We identified all adult hematological cancer patients and sampled a general population comparison cohort in a 1:5 ratio matched by age, sex, previous thromboembolic events, bleeding, and solid cancer. Ten-year absolute risks of thromboembolism and bleeding were calculated and hazard ratios (HRs) were computed, controlling for matching factors.

RESULTS

Among 32 141 hematological cancer patients, the 10-year absolute risk of any thromboembolic or bleeding complication following hematological cancer was 19%: 3.3% for MI, 3.5% for ischemic stroke, 5.2% for VTE, and 8.5% for bleeding. Except among patients with myeloid leukemia, acute lymphoid leukemia, or myelodysplastic syndrome, the risk of thromboembolic events surpassed that of bleeding. The hematological cancer cohort overall was at increased risk for MI [HR = 1.36, 95% confidence interval (CI): 1.25-1.49], ischemic stroke (HR = 1.22, 95% CI: 1.12-1.33), VTE (HR = 3.37, 95% CI: 3.13-3.64), and bleeding (HR = 2.39, 95% CI: 2.26-2.53) compared with the general population.

CONCLUSIONS

Approximately 2 of 10 hematological cancer patients experienced MI, ischemic stroke, VTE, or bleeding requiring hospital contact within 10 years. The hematological cancer cohort had higher hazards of MI, ischemic stroke, VTE, and bleeding requiring hospital contact than a general population comparison cohort.

Treatment of newly-diagnosed gastroesophageal reflux disease: a nationwide register-based cohort study

Objective: The aim of this study was to describe short-term treatment of gastroesophageal reflux disease (GERD) in patients registered with a GERD-diagnosis as part of evaluation with endoscopy using national Danish registers. Methods: The study population included all adults undergoing upper gastrointestinal endoscopy in Denmark from 1 January 2000 to 31 December 2015, who within 90 days received a diagnosis of GERD. We obtained nationwide data from The National Patient Registry on procedures (endoscopy and anti-reflux surgery) and diagnosis (GERD diagnosis and comorbidity), The Danish National Prescription Registry on the use of anti-reflux medication and ulcerogenic drugs, and The National Civil Registry on death and civil status. The primary outcome was a type of treatment of GERD within two years of primary endoscopy defined as either no treatment, medical treatment alone, surgical treatment alone or both medical and surgical treatment. Results: A total of 36,292 patients were included in the study. Endoscopies were performed without biopsies in 67.5% (n = 24,479) of cases. The majority (66.3%, n = 24,077) was registered as GERD with esophagitis. After initial endoscopy, 10.6% (n = 3862) received no pharmacological or surgical treatment for GERD within two years of follow-up, 87.5% (n = 31,761) received only pharmacological treatment, 0.1% (n = 50) received only surgical treatment and 1.7% (n = 619) received a combination of pharmacological and surgical treatment. Conclusion: Patients referred to investigation with endoscopy and diagnosed with GERD in Denmark are primarily treated with pharmacological anti-reflux treatment within the first two years with PPI being the primary agent. Only a small fraction of patients is treated surgically.

Early enteral nutrition versus delayed enteral nutrition in patients with gastrointestinal bleeding: A PRISMA-compliant meta-analysis

BACKGROUND

Controversy persists about whether early enteral nutrition administration is related to worse prognosis than delayed enteral nutrition for patients with gastrointestinal bleeding.

OBJECTIVES

To systematically evaluate the effect of early enteral nutrition on the patient with gastrointestinal bleeding through the meta-analysis.

METHODS

Such electronic databases including PubMed, EMBASE, Cochrane Library, CNKI, and CBM were searched from 1985 to March 2018. Randomized controlled trials that compared early enteral nutrition versus delayed enteral nutrition in patients with gastrointestinal bleeding were considered eligible. Data extraction and the methodological quality assessment of the included trials were carried out according to the Cochrane Handbook. We calculated the pooled risk ratio, weighted mean difference, and the corresponding 95% confidential interval using RevMan5.3.

RESULT

A total of 5 trials involving 313 patients were included. Compared with delayed enteral nutrition, there was a tendency for a decreased rebleeding rate in the early enteral nutrition group, but the trend was not statistically significant (risk ratio = 0.75, 95% confidential interval: 0.34-1.64, I = 0). As for mortality within 30 days, no significant difference was found between the 2 groups (risk ratio = 0.74, 95% confidential interval: 0.23-2.39, I = 0). In addition, the pooled analysis showed that early enteral nutrition was related to reduced hospitalized days (weighted mean difference = -1.69, 95% confidential interval: -2.15 to -1.23; I = 27%) CONCLUSION:: For patients with gastrointestinal bleeding, early enteral nutrition within 24 hours does not result in the significantly higher risk of rebleeding and mortality compared with delayed enteral nutrition, but decrease hospitalized days. Patients who are at low risk for rebleeding can be fed early and discharged early. However, larger, high-quality randomized controlled trials are needed to verify these findings, and when the gastrointestinal bleeding patient start enteral nutrition is worth studying.

International Consensus on Guiding Recommendations for Management of Patients with Nonsteroidal Antiinflammatory Drugs Induced Gastropathy-ICON-G

Introduction

Nonsteroidal anti-inflammatory drugs (NSAIDs), one of the most commonly used medications worldwide, are frequently associated with gastrointestinal adverse events. Primary care physicians often face the challenge of achieving adequate pain relief with NSAIDs, while keeping their adverse events to a minimum. This is especially true when long-term use of NSAIDs is required such as in patients with osteoarthritis and rheumatoid arthritis. To help primary care physicians deal with such challenges more effectively, a panel of expert gastroenterologists came together with the aim of developing practice recommendations.

Methods

A modified ‘Delphi’ process was used to reach consensus and develop practice recommendations. Twelve gastroenterologists from nine countries provided their expert inputs to formulate the recommendations. These recommendations were carefully developed taking into account existing literature, current practices, and expert opinion of the panelists.

Results

The expert panel developed a total of fifteen practice recommendations. Following are the key recommendations: NSAIDs should be prescribed only when necessary; before prescribing NSAIDs, associated modifiable and non-modifiable risk factors should be considered; H. pylori infection should be considered and treated before initiating NSAIDs; patients should be properly educated regarding NSAIDs use; patients who need to be on long-term NSAIDs should be prescribed a gastroprotective agent, preferably a proton pump inhibitor and these patients should be closely monitored for any untoward adverse events.

Conclusion/clinical significance

These practice recommendations will serve as an important tool for primary care physicians and will guide them in making appropriate therapeutic choices for their patients.

Risk factors of upper gastrointestinal hemorrhage with acute coronary syndrome

BACKGROUND

Research showed that the mortality of upper gastrointestinal hemorrhage (UGH) complicated with acute coronary syndrome (ACS) was higher than single UGH in elderly patients. This study aimed to determine the risk factors that associated with an increased risk of ACS occurrence after UGH.

METHODS

A population-based nested case-control study was conducted analyzing the hospital information system database of Shengjing Hospital of China Medical University from September 1, 2009 to December 31, 2014. We included 3217 elderly patients who experienced a UGH, among which 152 cases were identified and matched 604 selected controls. Multivariate conditional logistic regression models were used to characterize risk factors associated with ACS occurrence and death after UGH.

RESULTS

Diabetes (odds ratio (OR) = 1.84, 95% confidence interval (CI) 1.13-2.71, P = 0.039), smoking (OR = 1.87, 95% CI 1.19-2.73, P = 0.028), vasopressin or terlipressin use (OR = 1.51, 95% CI 1.02-2.14, P = 0.043), liver cirrhosis (OR = 2.43, 95% CI 1.45-4.38, P = 0.013), hemoglobin level (OR = 2.36, 95% CI 1.65-3.79, P = 0.014) and history of ACS (OR = 1.98, 95% CI 1.13-3.49, P = 0.017) increased risk of ACS incidence in elderly patients with UGH. Moreover, diabetes (OR = 2.14, 95% CI 1.15-4.21, P = 0.041), smoking (OR = 2.93, 95% CI 1.17-5.31, P = 0.043) and hemoglobin levels (OR = 1.95, 95% CI 1.24-3.16, P = 0.038) were independent variables for the mortality underwent UGH with ACS in elderly patients.

CONCLUSIONS

History of diabetes, vasopressin or terlipressin use, smoking, liver cirrhosis, hemoglobin level and history of ACS are risk factors to develop ACS in elderly patients with UGH. Importantly, diabetes, smoking and lower hemoglobin level are key variables for mortality.

Prehospital triage of patients diagnosed with perforated peptic ulcer or peptic ulcer bleeding: an observational study of patients calling 1-1-2

BACKGROUND

Triage systems are used in emergency medical services to systematically prioritize prehospital resources according to individual patient conditions. Previous studies have shown cases of preventable deaths in emergency medical services even when triage systems are used, indicating a potential undertriage among some conditions. The aim of this study was to investigate the triage level among patients diagnosed with perforated peptic ulcer (PPU) or peptic ulcer bleeding (PUB).

METHODS

In a three-year period in Central Denmark Region, all patients hospitalized within 24 h after a 1-1-2 emergency call and who subsequently received either a PPU or a PUB (hereinafter combined and referred to as PPU/PUB) or a First Hour Quintet (FHQ: respiratory failure, stroke, trauma, cardiac chest pain, and cardiac arrest) diagnosis were investigated. A modified Poisson regression was used to estimate the relative risk of receiving the highest and lowest prehospital response level. Also, a linear regression analysis was used to estimate the relative risk of 30-day mortality.

RESULTS

Of 8658 evaluated patients, 263 were diagnosed with PPU/PUB. After adjusting for relevant confounding variables, patients diagnosed with PPU/PUB were less likely to receive ambulance transportation compared to patients diagnosed with stroke, RR = 1.41 (CI: 1.28-1.56); trauma, RR = 1.28 (CI: 1.15-1.42); cardiac chest pain, RR = 1.47 (CI: 1.33-1.62); and cardiac arrest, RR = 1.44 (CI: 1.31-1.42). Among patients diagnosed with PPU/PUB, 6.5% (CI: 3.3-9.7) did not receive ambulance transportation. The proportion of patients not receiving ambulance transportation was higher among patients diagnosed with PPU/PUB compared to patients diagnosed with an FHQ diagnosis. The 30-day mortality rate among patients diagnosed with PPU/PUB was 7.8% (CI: 4.2-11.1). This was lower than the 30-day mortality rate among patients diagnosed with respiratory failure (P = 0.010), stroke (P = 0.001), and cardiac arrest (P < 0.001), but comparable to the 30-day mortality among patients diagnosed with cardiac chest pain (P = 0.080) and trauma (P = 0.281).

CONCLUSION

Among patients calling 1-1-2, fewer patients diagnosed with PPU/PUB received ambulance transportation than patients diagnosed with FHQ diagnoses, despite a high mortality among patients diagnosed with PPU/PUB.

Double Perforated Kissing Ulcers of Duodenum: A Brief Report

Helicobactor pylori infection has been associated with peptic ulcer disease and is currently treated with proton pump inhibitors (PPIs), which have reduced the complications of the disease. Perforation of either a gastric or duodenal ulcer is rarely treated with surgery. We report the case of double-perforated synchronous duodenal ulcers, which is an extremely infrequent condition. To our knowledge, no English case reports have yet been published. Therefore, awareness of the physician in the field of diagnosis and treatment of this peptic ulcer is required. We report the case of a 46-year-old male patient who presented with acute abdominal pain at the emergency surgical department of our hospital. According to patient history, smoking, alcohol consumption, and frequent postprandial abdominal pain were noted. A physical examination revealed a rigid abdomen and tachycardia, and the temperature was 37.8°C. Laboratory testing showed increased levels of leukocytes, and free subdiaphragmatic air was found in the chest X-ray. Due to rapid deterioration of his clinical condition, the patient underwent urgent surgery. An explorative laparotomy showed 2 perforated kissing ulcers at the first segment of the duodenum, in the anterior and posterior walls. A peripheral gastrectomy was performed. Postoperative follow-up did not result in any complications. In regard to this case we present, simultaneous perforation of two synchronous duodenal ulcers is an uncommon but possible incident of which the clinician should be aware. To our knowledge, this is the first case published in the literature.

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

BACKGROUND/AIMS

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

METHODS

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

RESULTS

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

CONCLUSION

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

Is it possible to reduce the surgical mortality and morbidity of peptic ulcer perforations?

Objective

Peptic ulcer perforation is a life-threatening situation requiring urgent surgical treatment. A novel vision in peptic ulcer perforation is necessary to fill the gaps created by antiulcer medication, aging of the patients, and presentation of resistant cases in our era. In this study, we aimed to share our findings regarding the effects of various risk factors and operative techniques on the mortality and morbidity of patients with peptic ulcer perforation.

Material and Methods

Data from 112 patients presenting at our Training and Research Hospital Emergency Surgery Department between January 2010 and December 2015 who were diagnosed with PUP through physical examination and laboratory and radiological tests and operated at the hospital have been retrospectively analyzed. Patients were divided into three groups based on morbidity (Group 1), mortality (Group 2), and no complication (Group 3).

Results

Of the 112 patients included in the study, morbidity was observed in 21 (18.8%), mortality in 11 (9.8%), and no complication was observed in 80 (71.4%), who were discharged with cure. The differences between group for the average values of the perforation diameter and American Society of Anesthesiologists, Acute Physiology and Chronic Health Evaluation II, and Mannheim Peritonitis Index scores were statistically significant (p<0.001 for each). The average values for the group with mortality were significantly higher than those of the other groups.

Conclusion

In this study where we investigated risk factors for increased morbidity and mortality in PUPs, there was statistically significant difference between the average values for age, body mass index, perforation diameter, and Acute Physiology and Chronic Health Evaluation II and Mannheim Peritonitis Index scores among the three groups, whereas the amount of subdiaphragmatic free air did not differ.

Erythromycin infusion prior to endoscopy for acute nonvariceal upper gastrointestinal bleeding: a pilot randomized controlled trial

BACKGROUND/AIMS

The aim of this study was to compare the effects of erythromycin infusion and gastric lavage in order to improve the quality of visualization during emergency upper endoscopy.

METHODS

We performed a prospective randomized pilot study. Patients presented with hematemesis or melena within 12 hours and were randomly assigned to the erythromycin group (intravenous infusion of erythromycin), gastric lavage group (nasogastric tube placement with gastric lavage), or erythromycin + gastric lavage group (both erythromycin infusion and gastric lavage). The primary outcome was satisfactory visualization. Secondary outcomes included identification of a bleeding source, the success rate of hemostasis, duration of endoscopy, complications related to erythromycin infusion or gastric lavage, number of transfused blood units, rebleeding rate, and bleeding-related mortality.

RESULTS

A total of 43 patients were randomly assigned: 14 patients in the erythromycin group; 15 patients in the gastric lavage group; and 14 patients in the erythromycin + gastric lavage group. Overall satisfactory visualization was achieved in 81% of patients: 92.8% in the erythromycin group; 60.0% in the gastric lavage group; and 92.9% in the erythromycin + gastric lavage group, respectively (p = 0.055). The identification of a bleeding source was possible in all cases. The success rate of hemostasis, duration of endoscopy, and number of transfused blood units did not significantly differ between groups. There were no complications. Rebleeding occurred in three patients (7.0%). Bleeding-related mortality was not reported.

CONCLUSIONS

Intravenous erythromycin infusion prior to emergency endoscopy for acute nonvariceal upper gastrointestinal bleeding seems to provide satisfactory endoscopic visualization.

Efficacy Comparison of Divided and Infusion Intravenous Pantoprazole Methods after Endoscopic Therapy in Patients with Acute Gastrointestinal Bleeding

Background:

Intravenous pantoprazole administration in patients with severe bleeding under urgent endoscopic therapy is effective. Furthermore, its infusion dose is useful to control bleeding; however, it is not economical. In this study, clinical outcomes and intravenous infusion of pantoprazole after endoscopic therapy plus efficacy of infusion dosage and divided doses are compared.

Materials and Methods:

This prospective, comparative study conducted on 18 adult (>18 years) patients referred to Al Zahra Hospital for hematemesis and melena bleeding who underwent endoscopic treatment with pantoprazole which divided into two groups of forty patients. First group received intravenous infusion for 80 mg and 8 mg/h. The second group received intravenous infusion with divided doses as 40 mg twice daily for 3 days. Clinical outcomes such as rebleeding, duration of hospitalization, amount of blood transfused, and mortality within 3 days after endoscopic treatment were collected and analyzed by SPSS software (version 20) using independent t-test, Chi-square test, and Fisher's exact test.

Results:

Duration of hospitalization in the pantoprazole infusion group was 5.42 ± 4.62 days, with three patients (7.5%) having rebleeding, and in the divided pantoprazole group was 5.90 ± 3.08 days, with four patients (10%) having rebleeding, and overall, only one person died in the divided pantoprazole group (2.5%) out of eighty patients. No significant difference was observed between two groups in terms of clinical outcomes (P > 0.05).

Conclusion:

Regarding to results, it can be stated that both methods with specified dosage had significant impact on improvement of hematemesis and melena. Furthermore, due to lower costs, low dose of pantoprazole in divided approach as 40 mg/12 h is proposed.

Randomized clinical trial: the impact of gastrointestinal risk factor screening and prophylactic proton pump inhibitor therapy in patients receiving dual antiplatelet therapy

OBJECTIVE

Dual antiplatelet therapy reduces the risk of ischemic complications after acute coronary syndrome, but increases the risk of bleeding including upper gastrointestinal bleeding (UGIB).The aim of this study was to examine the effect of screening for risk of UGIB and prophylactic proton pump inhibitor (PPI) treatment in dual-antiplatelet-treated patients at risk of UGIB and to assess the significance of dual antiplatelet therapy compliance for cardiovascular events.

PATIENTS AND METHODS

In a register-based randomized-controlled trial, 2009 patients were included at the time of first percutaneous coronary intervention and randomized to either screening or control. Screened high-risk patients were prescribed pantoprazole 40 mg during the 1-year after percutaneous coronary intervention.

RESULTS

The incidence of UGIB was 0.8 versus 1.3% in screened patients and controls, respectively (P=0.381).Significantly fewer screened patients (5.4%) than controls (8.0%) underwent upper gastrointestinal endoscopy (P=0.026). Screened patients (2.9%) had significantly fewer events of unstable angina pectoris than controls (4.7%) (P=0.036) and a higher compliance to dual antiplatelet therapy (88.3 vs. 85.0%) (P=0.035), but no statistically difference was observed in the incidences of myocardial infarction and all-cause mortality (1.0 vs. 1.5%) (P=0.422).

CONCLUSION

Screening for risk factors for UGIB and subsequent prophylactic PPI treatment did not significantly reduce the incidence of UGIB. Prescription of PPI was associated with a higher compliance with dual antiplatelet therapy and decreases the risk of recurrent cardiovascular events.

Scoring systems used to predict mortality in patients with acute upper gastrointestinal bleeding in the ED

OBJECTIVE

Acute upper gastrointestinal bleeding (UGIB) is a potentially life-threatening condition that requires rapid assessment in the emergency department (ED). We aimed to compare the performance of the AIMS65, Glasgow-Blatchford (Blatchford), preendoscopic Rockall (pre-Rockall), and preendoscopic Baylor bleeding (pre-Baylor) scores in predicting 30-day mortality in patients with acute UGIB in the ED setting.

METHODS

Consecutive patients with acute UGIB who were admitted to the ED ward during 2012-2016 were retrospectively recruited. Data were retrieved from the admission list of the ED using international classification of disease codes via computer registration. The predictive accuracy of these four scores was compared using the area under the receiver operating characteristic curve (AUC) method.

RESULTS

Among the 395 patients included during the study period, the total 30-day mortality rate was 10.4% (41/395). The AIMS65 and Glasgow-Blatchford scores performed better with an AUC of 0.907 (95% confidence interval (CI), 0.852-0.963; P<0.001) and 0.870 (95% confidence interval, 0.833-0.902; P<0.001) compared with other scoring systems (preendoscopic Rockall score: AUC, 0.709; 95% CI, 0.635-0.784; P<0.001; preendoscopic Baylor score: AUC, 0.523; 95% CI, 0.472-0.573; P>0.05).

CONCLUSION

In patients with acute UGIB in the ED, the AIMS65 and Glasgow-Blatchford scores are clinically more useful for predicting 30-day mortality than the preendoscopic Rockall and preendoscopic Baylor scores. The AIMS65 score might be more ideal for risk stratification in the ED setting.

Gastric Ulcer Complications after the Introduction of Proton Pump Inhibitors into Clinical Routine: 20-Year Experience

BACKGROUND

The aim of this study was to analyze the admissions and the management of peptic ulcer disease (PUD) in a tertiary care surgical center.

METHODS

We evaluated the medical records of all patients admitted to the University Hospital of Tübingen, Germany, for treatment of PUD during 1989-2008. Patients were included into the study if the diagnosis was verified endoscopically or surgically. Annual number of admissions, length of hospitalization, mortality rate, age, rate of non-steroidal anti-inflammatory drugs (NSAIDs) and proton pump inhibitor (PPI) medication, rate of Helicobacter pylori infection, and complications of PUD and surgery performed were recorded. Data were analyzed by descriptive analyses, Pearson's chi-square test, and regression analysis.

RESULTS

This study included 614 admissions. The number of annual admissions (31 ± 12), the length of hospitalization (9 ± 3 days), and the mortality rate (5 ± 4% per year) remained constant, whereas the age increased (1989: 52 ± 14 years vs. 2008: 67 ± 16 years). The rates of patients with H. pylori infection (47 ± 28% per year), NSAIDs treatment (29 ± 15% per year), and PPI treatment (31 ± 27% per year) remained constant. The most frequent PUD complication was hemorrhage (42 ± 16% per year), followed by perforation (9 ± 8% per year). During 1999-2008, more hemorrhages (125 vs. 121; p < 0.05) and perforations (40 vs. 21; p < 0.05) were registered than during 1989-1998. The rate of emergency surgery increased from 70% during 1989-1998 to 87% during 1999-2008. In contrast, elective surgery decreased from 21% during 1989-1998 to 7% during 1999-2008. Ulcer excision and oversewing was the most frequent surgical procedure performed (59%), with decreasing rates of acid-reducing surgery.

CONCLUSION

Despite recent advances in PUD management, ulcer hemorrhage and perforation remain a significant health burden and a surgical disease.

Positive predictive value of peptic ulcer diagnosis codes in the Danish National Patient Registry

Background

Diagnoses of peptic ulcer are registered in the Danish National Patient Registry (DNPR) for administrative as well as research purposes, but it is unknown whether the coding validity depends on the location of the ulcer.

Objective

To validate the International Classification of Diseases, 10^th revision diagnosis codes of peptic ulcer in the DNPR by estimating positive predictive values (PPVs) for gastric and duodenal ulcer diagnoses.

Methods

We identified all patients registered with a hospital discharge diagnosis of peptic ulcer from Aarhus University Hospital, Denmark, in 1995–2006. Among them, we randomly selected 200 who had an outpatient gastroscopy at the time of ulcer diagnosis. We reviewed the findings from these gastroscopies to confirm the presence of peptic ulcer and its location. We calculated PPVs and corresponding 95% confidence intervals (CIs) of gastric and duodenal ulcer diagnoses, using descriptions from the gastroscopic examinations as standard reference.

Results

In total, 182 records (91%) were available for review. The overall PPV of peptic ulcer diagnoses in DNPR was 95.6% (95% CI 91.5–98.1), with PPVs of 90.3% (95% CI 82.4–95.5) for gastric ulcer diagnoses, and 94.4% (95% CI 87.4–98.2) for duodenal ulcer diagnoses. PPVs were constant over time.

Conclusion

The PPV of uncomplicated peptic ulcer diagnoses in the DNPR is high, and the location of the ulcers is registered correctly in most cases, indicating that the diagnoses are useful for research purposes.

Plasma copeptin levels in the patients with gastrointestinal bleeding

INTRODUCTION

Gastrointestinal bleeding is a significant cause of morbidity and mortality worldwide. In addition, it constitutes an important part of health expenditures. In this study, we aimed to determine whether there is a relationship between plasma copeptin levels and the etiology, location and severity of gastrointestinal bleeding.

MATERIALS AND METHODS

This study was performed prospectively in 104 consecutive patients who were admitted to an emergency department with complaints of bloody vomiting or bloody or black stool. To evaluate the level of biochemical parameters such as Full Blood Count (FBC), serum biochemistry, bleeding parameters and copeptin, blood samples were obtained at admission. For the copeptin levels, 2 more blood samples were obtained at the 12th and 24th hours after admission. The values obtained were compared using statistical methods.

RESULTS

In terms of the etiology of bleeding, the copeptin levels in the patients with peptic ulcer were higher than the levels in patients with other gastrointestinal bleeding. However, the difference was not statistically significant. There were no significant differences among all groups' 0th, 12th and 24th hour levels of copeptin.

DISCUSSION

We conclude that copeptin cannot be effectively used as a biochemical parameter in an emergency department to determine the etiology and location of gastrointestinal bleeding. It can, however, be used to make decisions on endoscopy and the hospitalization of patients with suspected gastrointestinal bleeding.

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.

Prognostic factors in peptic ulcer perforations: a retrospective 14-year study

Regarding the complications of peptic ulcer, a perforation remains the most important fatal complication. The aim of our retrospective study was to determine relations between postoperative morbidity and comorbid disease or perioperative risk factors in perforated peptic ulcer. In total, 239 patients who underwent emergency surgery for perforated peptic ulcer in Ege University General Surgery Department, between June 1999 and May 2013 were included in this study. The clinical data concerning the patient characteristics, operative methods, and complications were collected retrospectively. One hundred seventy-five of the 239 patients were male (73.2%) and 64 were female (26.8%). Mean American Society of Anesthesiologists (ASA) score was 1 in the patients without morbidity, but mean ASA score was 3 in the morbidity and mortality groups. Primary suture and omentoplasty was the selected procedure in 228 of the patients. Eleven patients underwent resection. In total, 105 patients (43.9%) had comorbidities. Thirty-seven patients (67.3%) in the morbidity group had comorbid diseases. Thirteen (92.9%) patients in the mortality group had comorbid diseases. Perforation as a complication of peptic ulcer disease still remains among the frequent indications of urgent abdominal surgery. Among the analyzed parameters, age, ASA score, and having comorbid disease were found to have an effect on both mortality and morbidity. The controversial subject in the present study is regarding the duration of symptoms. The duration of symptoms had no effect on mortality nor morbidity in our study.

Increased short- and long-term mortality in 8146 hospitalised peptic ulcer patients

BACKGROUND

Incidence and complications of peptic ulcer disease (PUD) have declined, but mortality from peptic ulcer bleeding has remained unchanged. The few recent studies on mortality associated with both uncomplicated and complicated patients with peptic ulcer disease provide contradictory results.

AIMS

To evaluate short- and long-term mortality, and the main causes of death in peptic ulcer disease.

METHODS

In this retrospective epidemiologic cohort study, register data on 8146 adult patients hospitalised with peptic ulcer disease during 2000-2008 were collected in the capital region of Finland. All were followed in the National Cause of Death Register until the end of 2009. The data were linked with the nationwide Drug Purchase Register of the Finnish Social Insurance Institution.

RESULTS

Mean follow-up time was 4.9 years. Overall mortality was substantially increased, standardised mortality ratio 2.53 (95% CI: 2.44-2.63); 3.7% died within 30 days, and 11.8% within 1 year. At 6 months, the survival of patients with perforated or bleeding ulcer was lower compared to those with uncomplicated ulcer; hazard ratios were 2.06 (1.68-2.04) and 1.32 (1.11-1.58), respectively. For perforated duodenal ulcers, both the short- and long-term survival was significantly impaired in women. The main causes of mortality at 1 year were malignancies and cardiovascular diseases. Previous use of statins was associated with significant reduction in all-cause mortality.

CONCLUSIONS

One-year mortality in patients hospitalised with peptic ulcer disease remained high with no change. This peptic ulcer disease cohort had a clearly decreased survival rate up to 10 years, especially among women with a perforated duodenal ulcer, most likely explained by poorer survival due to underlying comorbidity.

Long-term risk of gastrointestinal cancers in persons with gastric or duodenal ulcers

Peptic ulcer predicts gastric cancer. It is controversial if peptic ulcers predict other gastrointestinal cancers, potentially related to Helicobacter pylori or shared lifestyle factors. We hypothesized that gastric and duodenal ulcers may have different impact on the risk of gastrointestinal cancers. In a nationwide cohort study using Danish medical databases 1994-2013, we quantified the risk of gastric and other gastrointestinal cancers among patients with duodenal ulcers (dominantly H. pylori-related) and gastric ulcers (dominantly lifestyle-related) compared with the general population. We started follow-up 1-year after ulcer diagnosis to avoid detection bias and calculated absolute risks of cancer and standardized incidence ratios (SIRs). We identified 54,565 patients with gastric ulcers and 38,576 patients with duodenal ulcers. Patient characteristics were similar in the two cohorts. The 1-5-year risk of any gastrointestinal cancer was slightly higher for gastric ulcers patients (2.1%) than for duodenal ulcers patients (2.0%), and SIRs were 1.38 (95% CI: 1.31-1.44) and 1.30 (95% CI: 1.23-1.37), respectively. The SIR of gastric cancer was higher among patients with gastric ulcer than duodenal ulcer (1.92 vs. 1.38), while the SIRs for other gastrointestinal cancers were similar (1.33 vs. 1.29). Compared with gastric ulcer patients, duodenal ulcer patients were at lower risk of smoking- and alcohol-related gastrointestinal cancers. The risk of nongastric gastrointestinal cancers is increased both for patients with gastric ulcers and with duodenal ulcers, but absolute risks are low. H. pylori may be less important for the development of nongastric gastrointestinal cancer than hypothesized.

The Danish National Patient Registry: a review of content, data quality, and research potential

Background

The Danish National Patient Registry (DNPR) is one of the world’s oldest nationwide hospital registries and is used extensively for research. Many studies have validated algorithms for identifying health events in the DNPR, but the reports are fragmented and no overview exists.

Objectives

To review the content, data quality, and research potential of the DNPR.

Methods

We examined the setting, history, aims, content, and classification systems of the DNPR. We searched PubMed and the Danish Medical Journal to create a bibliography of validation studies. We included also studies that were referenced in retrieved papers or known to us beforehand. Methodological considerations related to DNPR data were reviewed.

Results

During 1977–2012, the DNPR registered 8,085,603 persons, accounting for 7,268,857 inpatient, 5,953,405 outpatient, and 5,097,300 emergency department contacts. The DNPR provides nationwide longitudinal registration of detailed administrative and clinical data. It has recorded information on all patients discharged from Danish nonpsychiatric hospitals since 1977 and on psychiatric inpatients and emergency department and outpatient specialty clinic contacts since 1995. For each patient contact, one primary and optional secondary diagnoses are recorded according to the International Classification of Diseases. The DNPR provides a data source to identify diseases, examinations, certain in-hospital medical treatments, and surgical procedures. Long-term temporal trends in hospitalization and treatment rates can be studied. The positive predictive values of diseases and treatments vary widely (<15%–100%). The DNPR data are linkable at the patient level with data from other Danish administrative registries, clinical registries, randomized controlled trials, population surveys, and epidemiologic field studies – enabling researchers to reconstruct individual life and health trajectories for an entire population.

Conclusion

The DNPR is a valuable tool for epidemiological research. However, both its strengths and limitations must be considered when interpreting research results, and continuous validation of its clinical data is essential.

Diagnosis and therapy of non-variceal upper gastrointestinal bleeding

Non-variceal upper gastrointestinal bleeding (UGIB) is defined as bleeding proximal to the ligament of Treitz in the absence of oesophageal, gastric or duodenal varices. The clinical presentation varies according to the intensity of bleeding from occult bleeding to melena or haematemesis and haemorrhagic shock. Causes of UGIB are peptic ulcers, Mallory-Weiss lesions, erosive gastritis, reflux oesophagitis, Dieulafoy lesions or angiodysplasia. After admission to the hospital a structured approach to the patient with acute UGIB that includes haemodynamic resuscitation and stabilization as well as pre-endoscopic risk stratification has to be done. Endoscopy offers not only the localisation of the bleeding site but also a variety of therapeutic measures like injection therapy, thermocoagulation or endoclips. Endoscopic therapy is facilitated by acid suppression with proton pump inhibitor (PPI) therapy. These drugs are highly effective but the best route of application (oral vs intravenous) and the adequate dosage are still subjects of discussion. Patients with ulcer disease are tested for Helicobacter pylori and eradication therapy should be given if it is present. Non-steroidal anti-inflammatory drugs have to be discontinued if possible. If discontinuation is not possible, cyclooxygenase-2 inhibitors in combination with PPI have the lowest bleeding risk but the incidence of cardiovascular events is increased.

Perforated peptic ulcer

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

Study of the protective effect on intestinal mucosa of the hydrosoluble fiber Plantago ovata husk

Background

Several studies have indicated that dietary fiber may have a protective effect on gastrointestinal mucosa. The aim of this study was to evaluate the protective action of the soluble fiber Plantago ovata husk against intestinal damage.

Methods

To evaluate the anti-ulcerogenic effect on duodenal mucosa of the soluble fiber Plantago ovata husk, low-dose acetylsalicylic acid (10 mg/kg) was given orally to animals once daily for 14 or 28 days with and without Plantago ovata husk (100 mg/kg). 24 h after final dosing duodenal samples were removed for anatomopathological evaluation. Villi were examined by both light and scanning electron microscopy.

Results

Acetylsalicylic acid induced severe lesions in duodenal mucosa of rabbits, including erosions, epithelium disorganization, and cell vacuolization, increasing as well the amount of mononuclear and caliciform cells. Damage was much more severe in animals treated for 28 days. In groups receiving Plantago ovata husk, a significant attenuation of acetylsalicylic acid-induced lesions was already observed in group treated for 14 days, becoming more evident in those treated for 28 days, all of them with duodenal cytoarchitecture normal and similar to control animals.

Conclusions

These findings suggest that Plantago ovata husk may protect intestinal mucosa probably by limiting acetylsalicylic acid penetration into epithelial cells, although further studies are needed to confirm the same effect in other experimental models of induced mucosal damage and to elucidate the mechanisms of fiber protection.

Decreased stress resilience in young men significantly increases the risk of subsequent peptic ulcer disease - a prospective study of 233 093 men in Sweden

BACKGROUND

Psychosocial stress may influence peptic ulcer disease (PUD) risk, but it can be difficult to identify reliably whether stressful exposures pre-dated disease. The association of stress resilience (susceptibility to stress) with subsequent PUD risk has been incompletely investigated.

AIM

To assess if stress resilience in adolescence is associated with subsequent PUD risk.

METHODS

The participants comprised of 233 093 men resident in Sweden, born 1952-1956 and assessed for compulsory military conscription during 1969-1976, with data provided by national Swedish registers. Stress resilience was evaluated through semi-structured interviews by a certified psychologist. Cox regression assessed the association between stress resilience in adolescence and the risk of PUD from 1985 to 2009, between ages 28 and 57 years, with adjustment for parental socioeconomic index, household crowding and number of siblings in childhood, as well as cognitive function and erythrocyte sedimentation rate in adolescence.

RESULTS

In total, 2259 first PUD diagnoses were identified. Lower stress resilience in adolescence is associated with a higher risk of PUD in subsequent adulthood: compared with high resilience, the adjusted hazard ratios (and 95% CI) are 1.84 (1.61-2.10) and 1.23 (1.09-1.38) for low and moderate stress resilience, respectively.

CONCLUSION

Stress may be implicated in the aetiology of PUD and low stress resilience is a marker of risk.

[Incidence and predictive factors of iron deficiency anemia after acute non-variceal upper gastrointestinal bleeding without portal hypertension]

INTRODUCTION

There are few studies on iron deficiency anemia (IDA) after non-variceal acute upper gastrointestinal bleeding (UGIB) in patients without portal hypertension.

OBJECTIVES

To define the incidence of IDA after UGIB, to characterize the predictive factors for IDA and to design algorithms that could help physicians identify those patients who could benefit from iron therapy.

MATERIAL AND METHOD

We registered 391 patients with UGIB between April 2007 and May 2009. Patients with portal hypertension and those with clinical or/and biological conditions that could affect the ferrokinetic pattern were excluded. Blood analyses were performed, including ferric parameters upon admission, on the 5th day, and on the 30th day after the hemorrhage episode. We used a multiple logistic regression model and a classification and regression tree model.

RESULTS

A total of 124 patients were included, of which 76 (61.3%) developed IDA 30 days after UGIB. The predictive variables were age >75 years (P=.037; OR 3.9; 95% CI: 1.3-11.6), initial urea level >80mg/dL (P=.027; OR 2.9; 95% CI: 1.1-7.6), initial ferritin level ≤65ng/dL (P=.002; OR 7.6; 95% CI: 2.9-18.5), initial hemoglobin level ≤100g/L (P=.003; OR 3.2; 95% CI: 1.3-8.0), hemoglobin level on the 5th day ≤100g/L (P<.001; OR 14.9; 95% CI: 3.6-61.1) and the value of the transferrin saturation index on the 5th day <10% (p<0.001; OR 7.2; 95% CI: 2.6-20.3).

CONCLUSIONS

Most patients with UGIB developed IDA 30 days after the episode. Identification of the predictive factors for IDA may help to establish guidelines for the administration of iron therapy.

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

Aim

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

Methods

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

Results

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

Conclusion

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

Chronic liver disease and 90-day mortality in 21,359 patients following peptic ulcer bleeding--a Nationwide Cohort Study

BACKGROUND

Bleeding is a serious and frequent complication of peptic ulcer disease. Hepatic dysfunction can cause coagulopathy and increases the risk of peptic ulcer bleeding. However, whether chronic liver disease increases mortality after peptic ulcer bleeding remains unclear.

AIM

To examine the prognostic impact of chronic liver disease on mortality after peptic ulcer bleeding.

METHODS

We used population-based medical registries to conduct a cohort study of all Danish residents hospitalised with incident peptic ulcer bleeding from 2004 through 2011. We identified patients diagnosed with liver cirrhosis or non-cirrhotic chronic liver disease before their admission for peptic ulcer bleeding. We then computed 90-day mortality after peptic ulcer bleeding based on the Kaplan-Meier method (1 - survival function) and used a Cox regression model to estimate mortality rate ratios (MRRs), controlling for potential confounders.

RESULTS

We identified 21,359 patients hospitalised with peptic ulcer bleeding. Among these, 653 (3.1%) had a previous diagnosis of liver cirrhosis and 474 (2.2%) had a history of non-cirrhotic chronic liver disease. Patients with liver cirrhosis and non-cirrhotic chronic liver disease had a cumulative 90-day mortality of 25.3% and 20.7%, respectively, compared to 18.3% among patients without chronic liver disease. Liver cirrhosis was associated with an adjusted 90-day MRR of 2.38 (95% CI: 2.02-2.80), compared to 1.49 (95% CI: 1.22-1.83) among patients with non-cirrhotic chronic liver disease.

CONCLUSION

Patients with chronic liver disease, particularly liver cirrhosis, are at increased risk of death within 90 days after hospitalisation for peptic ulcer bleeding compared to patients without chronic liver disease.
