Use Of H2-receptor Antagonists Research Articles

Association Between Risk of Clostridium difficile Infection and Duration of Proton Pump Inhibitor or H2-Receptor Antagonist Use in Hospitalized Patients.

Limited studies have evaluated the association between Clostridium difficile infection (CDI) and the duration of proton pump inhibitor (PPI) or histamine H2-receptor blocker (H2RA) use and provided a cutoff duration for PPI or H2RA use to mitigate a substantially increased risk of CDI. We aimed to evaluate these associations in hospitalized patients using a nationwide insurance claims database. We conducted a nested case-control study to identify cases with a first ever record of CDI in a study cohort undergoing PPI or H2RA therapy from the National Health Insurance Database from 2012 to 2018. Each case was matched with one control by age, sex, and calendar year. We used conditional logistic regression to estimate the sensitivity, specificity, and area under the receiver operating characteristic curve (AUC ROC). Youden's Jstatistic was used to identify the optimal cutoff duration in days for PPI or H2RA use. In the main analysis, the AUC ROC was 0.64 (95%CI 0.63-0.66) and optimal cutoff duration was 15days for PPI users. The AUC ROC was 0.63 (95%CI 0.62-0.64) and optimal cutoff duration was 16days for H2RA users. In the sensitivity analyses, the results were similar to those of the main analysis, and the optimal cutoff duration was in the range of 14-15days. The optimal cutoff duration for PPI and H2RA use was about 2weeks. It is necessary to be cautious regarding the risk of CDI in patients taking PPIs or H2RAs for longer than 2weeks.

Analysis of Barrett’s Esophagus and Its Risk Factors: A Cross-Sectional Study of 10,122 Subjects at a Japanese Health Examination Center

Introduction: Helicobacter pylori eradication is expected to significantly change the prevalence of Barrett’s esophagus (BE). However, few reports on this relationship exist. We analyzed the risk factors of BE using the current consensus on length of BE considering H. pylori infection status. Methods: We analyzed 10,122 individuals (5,962 men; mean age = 52.9 ± 9.9 years) who had undergone esophagogastroduodenoscopy as part of a medical checkup. Correlations among factors including H. pylori infectious status, endoscopic findings, and BE ≥1 cm were analyzed. Results: Prevalence of BE, long-segment BE, and esophageal adenocarcinoma was 22.5%, 0.014%, and 0%, respectively. Logistic regression analysis showed that the risk factors for BE were hiatal hernia (odds ratio [OR]: 2.89 [2.59–3.24]), female sex (OR: 0.52 [0.46–0.59]), social drinking (OR:0.77 [0.68–0.87]), H. pylori eradication therapy (OR: 1.34 [1.19–1.51]), proton pump inhibitor (PPI) use (OR: 1.52 [1.18–1.96]), bile reflux (OR: 1.18 [1.04–1.33]), age ≥50 years (OR: 1.13 [1.02–1.26]), and nonsteroidal anti-inflammatory drug (NSAID) use (OR: 1.29 [1.02–1.62]). Although reflux esophagitis (RE) was more common in H. pylori-negative patients (17.2%) than in those after H. pylori eradication therapy (11.8%, p < 0.00001), the latter was correlated with BE, disputing RE as a strong risk factor for BE. Therefore, we conducted a subgroup analysis; most of the risk factors except for PPI use (p = 0.75), H2-receptor antagonist use (p = 0.078), and atrophic gastritis absence (p = 0.72) were positively correlated with BE after H. pylori eradication therapy compared with H. pylori-negative status. Conclusions: H. pylori eradication, bile reflux, PPI use, and NSAID use were risk factors for BE along with hiatal hernia, male sex, and older age.

Factors Associated With Poor Outcomes Among Patients With SARS-CoV-2 Coronavirus Infection and Gastrointestinal Symptoms

Background & AimsGastrointestinal (GI) symptoms are present in 20% of patients with COVID-19. We studied the association of GI symptoms (in COVID-19 patients) with adverse outcomes and factors associated with poor outcomes in these patients.MethodsThe study cohort included 100,902 patients from the Cerner Real World Data (CRWD) COVID-19 Database of hospital encounters and emergency department (ER) visits with COVID-19 infection from December 1, 2019, to November 30, 2020. Multivariate analysis was used to study the effect of GI symptoms on adverse outcomes, and the factors associated with acute respiratory distress syndrome (ARDS), sepsis, and ventilator requirement or oxygen dependence in COVID-19 patients with GI symptoms.ResultsPatients with COVID-19 and GI symptoms were significantly more likely to have ARDS (OR 1.20, 95% CI 1.11, 1.29), sepsis (OR 1.19, 95% CI 1.14, 1.24), acute kidney injury (OR 1.30, 95% CI 1.24, 1.36), venous thromboembolism (OR 1.36, 95% CI 1.22, 1.52) or GI bleed (OR 1.62, 95% CI 1.47, 1.79); and less likely to experience cardiomyopathy (OR 0.87, 95% CI 0.77, 0.99) or death (OR 0.71, 95% CI 0.67, 0.75). Among those with GI symptoms, older age, higher Charlson comorbidity index scores, and use of proton pump inhibitors (PPI)/ H2 receptor antagonists (H2RA) were associated with higher mortality, ARDS, sepsis, and ventilator or oxygen requirement.ConclusionPatients with COVID-19 who have GI symptoms have overall worse in-hospital complications, but less cardiomyopathy and mortality. Older age, higher comorbidity scores, and the use of PPI and H2RA are associated with poor outcomes in these patients.

The Association of Long-Term Use of Proton Pump Inhibitors and Histamine H2 Receptor Antagonists with Clinical Complications in Patients with Severe Sepsis.

Objective Proton pump inhibitors (PPIs) are commonly used to treat gastric acidity, and their frequent use may trigger various malfunctioning, such as cardiac, renal, and liver function failure. In the current study, we evaluated the association between the excessive use of the PPIs and the clinical complications of intensive care unit (ICU) septic patients. Methods A total of 208188 patients were analyzed from 2016 to 2017 through the China Critical Care Sepsis Trial (CCCST) database. The characteristics of the study group and outcome of events from the PPI- and H2 blocker-using groups were reported. To get unbiased results, the data from the target trials were randomly assigned for PPI and H2 blocker groups. Result The data revealed 43.34 excess deaths (95% confidence intensive (CI) 25.12 to 62.02) per 1000 patients in patients extensively consuming PPI drugs. The sepsis with chronic kidney disease attributed to deaths 21.36; 95% CI (9.34 to 23.23). However, comorbidities, including circulatory diseases (16.34; 95% CI 5.78 to 23.45), nervous system (2.08; 95% CI 1.56 to 6.34), mental disorders (1.87; 95% CI 1.65 to 2.95), genitourinary system (5.23; 95% CI 3.69 to 8.89), and infectious and parasitic disease (4.17; 95% CI 1.44 to 7.49), were also reported. Extensive use of the PPIs and H2 blockers was associated with esophageal adenocarcinoma, Barrett's esophagus, neoplasms, and GI cancers. Conclusion We conclude that the excessive use of PPI in sepsis patients triggers chronic kidney disease which has a higher clinical complication rate among others.

Trends in proton pump inhibitor use, reflux esophagitis, and various upper gastrointestinal symptoms from 2010 to 2019 in Japan.

The increasing usage of proton pump inhibitors (PPIs) has been reported worldwide, but information on PPI use in East Asia is inadequate. This study aimed to examine the trends in PPI use in Japan, along with the changes in histamine H2 receptor antagonist (H2RA) use, disease rate of reflux esophagitis, and the prevalence of upper gastrointestinal symptoms. We analyzed 217,712 healthy subjects (127,607 men and 90,105 women; 51.4 ± 9.7 years old) participating in the health check program from 2010 to 2019. Various upper gastrointestinal symptoms were evaluated using the frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) questionnaire. Reflux esophagitis was diagnosed by esophageal erosion using the Los Angeles classification grades A, B, C, and D. From 2010 to 2019, the percentage of PPI users increased markedly from approximately 1.8% to 5.3%, whereas that of H2RA users decreased gradually from approximately 2.5% to 1.9%. The use of all classical types of PPIs (omeprazole, lansoprazole, rabeprazole, and esomerazole) and a new type of PPI, a potassium-competitive acid blocker (vonoprazan), greatly increased during the 10 years. An upward trend in the prevalence of reflux esophagitis was observed from 2010 to 2015, but not from 2016 to 2019, indicating that the monotonic rising prevalence of reflux disease stopped in the middle of the 2010s in Japan. In contrast, various upper gastrointestinal symptoms significantly improved between 2010 and 2019. All 12 FSSG symptoms of PPI users were significantly worse than those of non-PPI users, suggesting that PPIs still cannot completely control upper gastrointestinal symptoms. In conclusion, this study revealed a significant increase in PPI use and a slight decrease in H2RA use from 2010 to 2019. Despite a plateau in the prevalence of reflux esophagitis and considerable improvement in various upper gastrointestinal symptoms, PPI use has continued to increase in Japan.

Exposure to Proton Pump Inhibitors and the Risk of Incident Asthma in Patients with Coronary Artery Diseases: A Population-Based Cohort Study

We aimed to determine the association between proton pump inhibitor (PPI) use and incident asthma in patients with coronary artery disease (CAD). This nationwide cohort study collected claims data from the Taiwanese Bureau of National Health Insurance from 2004 to 2013. The primary outcome, i.e., the risk of incident asthma, was assessed by estimating hazard ratios (HRs) and 95% confidence intervals (CIs). The adjusted HR of asthma development was estimated using the Cox regression model. Sensitivity and subgroup analyses were also conducted. A total of 8894 PPI users and 12,684 H2-receptor antagonist (H2RA) users were included in patients with CAD. Compared with H2RA use, an increased risk of incident asthma was found between PPI use and the risk of incident asthma in patients with CAD after adjusting for sex, age, urbanization, and low income (HR: 1.41; 95% CI: 1.04–1.89). The sensitivity analysis results were consistent with the main analysis results. However, the subgroup analysis revealed no association of incident asthma in patients with diabetes mellitus, hyperlipidemia, stroke, allergic rhinitis, pneumonia, cancer, or depression in the PPI group compared with those in the H2RA group. In conclusion, PPI use increased the risk of asthma development in patients with CAD.

Possible Association between the Use of Proton Pump Inhibitors and H2 Receptor Antagonists, and Esophageal Cancer: A Nested Case-Control Study Using a Korean National Health Screening Cohort.

Although safety concerns regarding proton pump inhibitor (PPI)/H2-receptor antagonists (H2RA) in the incident esophageal cancer have been raised, the Asian-based report is unclear. We investigated the estimated likelihood of incident esophageal cancer—its mortality depending on prior history of PPI/H2RA use—and gastroesophageal reflux disease (GERD) in Koreans. Using the Korean National Health Insurance Service-Health Screening Cohort data (2002–2015), a case–control study was retrospectively conducted, including 811 patients with incident esophageal cancer and 3244 controls matched with sex, age, income, and residence. Propensity score overlap weighting was adjusted to balance the baseline covariates. Overlap propensity score-weighted logistic regression analyses were assessed to determine associations of the prior exposure of PPI/H2RA (current vs. past) and the medication duration (<30-, 30–90-, vs. ≥90-days) with incident esophageal cancer and its mortality among the total participants or those with/without the GERD episodes, after adjusting for multiple covariates including PPI/H2RA. The current exposure to either PPI or H2RA showed higher odds for incident esophageal cancer than the nonuser group ([13.23; 95%CI 10.25–17.06] and [4.34; 95%CI 3.67–5.14], respectively), especially in all adults over the age of 40 years without GERD. Both current and past exposures to PPI showed a decreased probability of mortality compared with those of the nonuser group ([0.62; 95%CI 0.45–0.86] and [0.41; 95%CI 0.25–0.67], respectively). However, current or past exposure to H2RA harbored the mutually different likelihoods for mortality depending on the presence of GERD and old age. This study carefully speculates on the possible link between PPI/H2RA and incident esophageal cancer in the Korean population. Mortality appears to be affected by certain risk factors depending on drug types, exposure history, old age, and the presence of GERD.

Minimizing the "Kitchen Sink" Approach: De-implementation of Unnecessary Care for Patients with Anaphylaxis in a Pediatric Emergency Department.

Introduction:Epinephrine is the only medication that prevents morbidity and mortality in anaphylaxis. Systemic corticosteroids and H2 receptor antagonists (H2RA) may benefit select cases but are not universally indicated. This study aims to de-implement the universal use of steroids and H2RAs and emphasize epinephrine-focused care for children with anaphylaxis during acute care visits. The study aims to reduce steroid and H2RA use from 81% and 60%, respectively, to 30% by December 2019.Methods:The primary outcome measures were the percent of patients receiving steroids and H2RAs in the emergency department (ED) or urgent care (UC). Process measure was the frequency of intravenous (IV) line placement. Balancing measures were ED/UC length of stay, admission rate, and ED/UC return visit rate. In addition, a multidisciplinary team designed the following interventions: (1) anaphylaxis clinical pathway to emphasize epinephrine-focused care, outline criteria for second-line therapies and a provider guideline for ED/UC observation; (2) standardize unit-based anaphylaxis medication kits; (3) optimize electronic medical record tools, including order sets and discharge instructions to be concordant with guideline recommendations.Results:The study included 870 patients. There was special cause variation in the use of steroids (81%–33%) and H2RAs (60%–11%), ED/UC Length of stay decreased (6.2–5.0 hours). There was no special cause variation in admission rates or ED/UC return visit rates.Conclusion:Universal use of systemic steroids and H2RAs can be safely de-implemented in pediatric patients with anaphylaxis using quality improvement methods.

Association Between Regular Use of Gastric Acid Suppressants and Subsequent Risk of Cholelithiasis: A Prospective Cohort Study of 0.47 Million Participants.

Background: Gastric acid suppressants have a major impact on gut microbiome which in turn, may increase the risk of cholelithiasis, but epidemiological evidence remains unclear. We undertook this research to evaluate the association between regular use of proton pump inhibitors (PPIs) and H2-receptor antagonists (H2RAs) with risk of cholelithiasis. Methods: Prospective cohort study included 477,293 UK residents aged 37–73 years from the UK Biobank. We included the participants reported PPI or H2RA use, and were free of cholelithiasis or cancer. We evaluated hazard ratios (HRs) of regular use of PPIs or H2RAs and risk of cholelithiasis adjusting for demographic factors, lifestyle habits, the presence of comorbidities, use of other medications, and clinical indications. Results: We identified 12,870 cases of cholelithiasis over a median follow-up of 8.1 years. Regular use of PPIs (HR 1.22 95% CI 1.16–1.29) or H2RAs (HR 1.16, 95% CI 1.05–1.28) was associated with an increased risk of cholelithiasis after confounding adjustment. There were no major differences among individual PPIs/H2RAs. The absolute risk of PPI-associated cholelithiasis was increased with the baseline predicted risk evaluated by known environmental and genetic risk factors (Risk differences in the lowest vs. the highest quartile: 1.37 vs. 4.29 per 1,000 person-years). Conclusion: Regular use of PPIs and H2RAs was associated with increased risk of cholelithiasis. Future prospective studies are required to confirm whether the observed associations are casual.

Acid suppressant use in association with incidence and severe outcomes of COVID-19: a systematic review and meta-analysis.

PurposeSeveral observational studies have presented conflicting results on the association between the use of proton pump inhibitors (PPIs) or histamine H2 receptor antagonist (H2RA) and the risk of coronavirus disease 2019 (COVID-19). This systematic review and meta-analysis aimed to examine this association.MethodsIn July 2021, PubMed, Embase, Cochrane Central Register of Controlled Trials, and Web of Science were searched for articles investigating the relationship between the two main acid suppressants and COVID-19. Studies showing the effect estimates as hazard ratio (HR) for severe outcomes or incidence of COVID-19 were evaluated using a random-effects model.ResultsA total of 15 retrospective cohort studies with 18,109 COVID-19 cases were included in the current meta-analysis. PPI use was significantly associated with severe outcomes of COVID-19 (hazard ratio [HR] = 1.53; 95% confidence interval [CI]: 1.20–1.95) but not with the incidence of COVID-19, whereas H2RA use was significantly associated with decreased incidence (HR = 0.86, 95% CI: 0.76–0.97). For subgroup analyses of PPIs, increased severe outcomes of COVID-19 were observed in < 60 years, active use, in-hospital use, and Asians. For subgroup analyses of H2RAs, decreased severe outcomes of COVID-19 were observed in > 60 years, while in-hospital use and use in Asia were associated with higher disease severity.ConclusionsClose observation can be considered for COVID-19 patients who use PPIs to prevent severe outcomes. However, caution should be taken because of substantial heterogeneity and plausible protopathic bias.Supplementary informationThe online version contains supplementary material available at 10.1007/s00228-021-03255-1.

Use of acid-suppressive drugs and risk of fracture in children and young adults: a meta-analysis of observational studies.

Acid-suppressive drugs (ASDs) are being used by increasing number of children and young adults. However, evidence for a relationship between ASD use and the risk of fracture in these groups of patients is conflicting. We conducted a meta-analysis to evaluate the risk of fracture in children and young adults exposed to ASDs. A literature search was performed using the PUBMED, EMBASE, and Cochrane Library databases from inception to November 2020. Pooled relative risks (RRs) and 95% confidence intervals (CIs) were calculated to determine the relationship of ASD use with fracture risk in children and young adults. Six studies reporting the outcomes of more than 900,000 children and young adults with ASD use were included in the meta-analysis. The pooled RR for fracture with the use of proton pump inhibitors (PPIs) versus non-use of these medications was 1.17 (95% CI = 1.1-1.25; P < 0.001) in children and 1.2 (95% CI = 0.87-1.65; P = 0.272) in young adults. By contrast, the use of histamine H2-receptor antagonists (H2RAs) was not significantly associated with fracture risk in children (RR, 1.08, 95% CI = 0.99-1.17; P = 0. 083) or young adults (RR, 1.08, 95% CI = 0.82-1.42; P = 0.589). Significant statistical and clinical heterogeneity among studies were determined for the main analysis and most of the subgroup analyses. Our study provides evidence linking PPI use to an increased risk of fracture in children. Thus, the use of PPIs in these patients should be carefully considered. However, randomized controlled studies are needed to determine causality and the role of unmeasured/residual confounding factors in this association.

Risk of Enteric Infection in Patients with Gastric Acid Supressive Drugs: A Population-Based Case-Control Study.

: BackgroundLong-term use of gastric-acid-suppressive drugs is known to be associated with several adverse effects. However, the association between enteric infection and acid suppression therapy is still uncertain. This study aimed to evaluate the association between gastric acid suppression and the risk of enteric infection. Materials and Methods: We conducted a population-based case-control study using the data from Chang Gung Research Database (CGRD) in Taiwan. Between January 2008 and December 2017, a total of 154,590 adult inpatients (age > 18) were identified. A pool of potential eligible controls according to four propensity scores matching by sex, age, and index year were extracted (n = 89,925). Subjects with missing data or who received less than 7 days of proton pump inhibitors (PPIs) and/or H2-receptor antagonists (H2RAs) were excluded. Finally, 17,186 cases and 69,708 corresponding controls were selected for analysis. The use of PPIs and H2RAs, the result of microbiological samples, and co-morbidity conditions have been analyzed. Confounders were controlled by conditional logistic regression. Results: 32.84% of patients in the case group used PPIs, compared with 7.48% in the control group. Of patients in the case group, 9.9% used H2RAs, compared with 6.9% in the control group. Of patients in the case group, 8.3% used a combination of PPIs and H2RAs, compared with 2.7% in the control group. The most common etiological pathogens were Enterococcus (44.8%), Clostridioides difficile (34.5%), and Salmonella spp. (10.2%). The adjusted odds ratio (OR) for PPI use with enteric infection was 5.526 (95% confidence interval [CI], 5.274–5.791). For H2RAs, the adjusted odds ratio was 1.339 (95% confidence interval [CI], 1.261–1.424). Compared to the control group, persons with enteric infection had more frequent acid-suppressive agent usage. Conclusions: This study demonstrates that gastric-acid-suppressive drug use is associated with an increased risk of enteric infection after adjusting for potential biases and confounders.

S441 The Association Between Chronic PPI Use and COVID-19 Infection

Introduction: Proton pump inhibitors (PPIs) are well-tolerated antisecretory agents used to treat acid-peptic disorders, but chronic use has been associated with increased risk of gastrointestinal (GI) infections. Novel coronavirus is a respiratory illness that causes COVID-19, but has also been shown to infect the GI tract. Recent work has supported an association between COVID-19 and PPI use. Our study aimed to validate the association between PPI use and increased risk of COVID-19 and to investigate the severity of infection in these patients. Methods: Patients from a large community hospital aged 18 and older with a positive COVID-19 test (cases) (n = 299) were compared with those who tested negative (controls) (n = 601). Age, gender, race, BMI, history of tobacco or alcohol use, and certain comorbidities (diabetes mellitus, asthma, chronic obstructive pulmonary disease, cirrhosis, chronic kidney disease, and malignancy) were matched using propensity score matching (PSM) to minimize confounding variables. The rate of positive COVID-19 tests versus negative COVID-19 tests was compared among those using only chronic PPI (greater than 3 months), only H2-receptor antagonist use (H2RA), and combination therapy of PPI and H2RA. Subgroup analysis was also performed among positive COVID-19 cases to assess the rate of hospitalization, intensive care unit needs, ventilator dependence, and death. Results: Chronic PPI use showed no increased risk of COVID-19 (OR 0.42, 95% CI 0.3384-0.5096, P = 0.0805) (Table 1). H2RA therapy as well as combination therapy also did not have an increased risk of testing positive for COVID-19 (OR 0.37, 95% CI 0.2445-05170, P = 0.0823 and OR 0.55, 95% CI 0.3807-0.7151, P = 0.5455, respectively) (Figure 1). Among patients with COVID-19 who took PPI and/or H2RA, 14.46% were hospitalized, 16.67% required mechanical ventilation, 41.67% required intensive care, and there was 8.33% mortality. Patients on PPI and/or H2RA therapy were not more likely to be hospitalized, require mechanical ventilation or intensive care, or have increased risk of mortality compared with those who did not take either medication (P = 0.6813, P = 0.3679, P = 0.6703, P = 0.0654). Conclusion: Chronic PPI use (with or without H2RA use) does not increase the risk of COVID -19. Patients who did test positive for COVID-19 while on chronic PPI were not more likely to be hospitalized and did not require higher levels of care. PPIs should continue to be used in the proper patients regardless if they are positive for COVID-19.Table 1.: Comparison of chronic PPI use, H2RA, and combination therapy in those who tested positive for COVID-19 and those who tested negative.Figure 1.: Comparison of chronic PPI use, H2RA, and combination therapy in those who tested positive for COVID-19 and those who tested negative.

Histamine H2-Receptor Antagonists Improve Non-Steroidal Anti-Inflammatory Drug-Induced Intestinal Dysbiosis

Dysbiosis, an imbalance of intestinal flora, can cause serious conditions such as obesity, cancer, and psychoneurological disorders. One cause of dysbiosis is inflammation. Ulcerative enteritis is a side effect of non-steroidal anti-inflammatory drugs (NSAIDs). To counteract this side effect, we proposed the concurrent use of histamine H2 receptor antagonists (H2RA), and we examined the effect on the intestinal flora. We generated a murine model of NSAID-induced intestinal mucosal injury, and we administered oral H2RA to the mice. We collected stool samples, compared the composition of intestinal flora using terminal restriction fragment length polymorphism, and performed organic acid analysis using high-performance liquid chromatography. The intestinal flora analysis revealed that NSAID [indomethacin (IDM)] administration increased Erysipelotrichaceae and decreased Clostridiales but that both had improved with the concurrent administration of H2RA. Fecal levels of acetic, propionic, and n-butyric acids increased with IDM administration and decreased with the concurrent administration of H2RA. Although in NSAID-induced gastroenteritis the proportion of intestinal microorganisms changes, leading to the deterioration of the intestinal environment, concurrent administration of H2RA can normalize the intestinal flora.

Some Risk Factors for Hospital Infections at the ICU in the Vietnam National Children’s Hospital

Purpose: To identify some risk factors for hospital infections in the ICU, Vietnam National Children’s Hospital in 2018-2019.&#x0D; Method: A prospective cohort study was conducted.&#x0D; Results: Malnutrition grade II or higher, PRISM &gt; 10, ≥ 3 invasive intervention, use of H2-receptor antagonists and intravenous feeding were risk factors for nosocomial infections. Endotracheal intubation, intubation for &gt; 5 days, re-intubation, and aspiration of vomit were risk factors for nosocomial pneumonia. Intravenous exposure, 3 or more IV lines, and central venous catheterization were risk factors for sepsis. Gastrointestinal surgery, surgery time &gt; 2 hours, postoperative drainage, drainage time &gt; 5 days and no prophylactic antibiotics were risk factors for wound infection. Urinary retention and urinary flow &gt; 3 days were risk factors for urinary tract infections.&#x0D; Conclusion: Nosocomial infections with grade II or higher malnutrition and 3 invasive interventions, the use of H2-receptor resistance and intravenous nutrition associated with nosocomial infections. Pneumonia, urinary tract infections, and sepsis are high risk factors for nosocomial infections.

Risk of Adverse Cardiovascular Events Following a Myocardial Infarction in Patients Receiving Combined Clopidogrel and Proton Pump Inhibitor Treatment: A Nested Case-Control Study.

BackgroundThe clinical implications of potential interactions between proton pump inhibitors (PPIs) and clopidogrel have been debated for over a decade.ObjectiveWe assessed the association between combined clopidogrel–PPI treatment and the risk of recurrent myocardial infarction (MI) and three secondary outcomes.Patients and MethodsA nested case–control study was conducted within Cerner Corporation’s Health Facts® database. A retrospective cohort of patients who experienced a first MI and started clopidogrel treatment was created. Within this cohort, patients experiencing a second MI (cases) were matched with up to five controls. Logistic regression was used to estimate adjusted odds ratios (aORs). Findings were compared with those obtained from models with three negative control exposure drugs: H2 receptor antagonists, prasugrel, and ticagrelor.ResultsIn total, 2890 recurrent MI cases were identified within 12 months following entry into the cohort of clopidogrel users (N = 52,006). aOR for PPI use versus non-use among clopidogrel users was 1.08 [95% confidence interval (CI) 0.95–1.23]. Similar ORs were obtained for secondary endpoints. A positive association between combined use of clopidogrel/PPIs and increased risk of MI was seen in the group aged 80–89 years (aOR 1.26; 95% CI 1.05–1.51). No associations with MI were observed for (1) H2 receptor antagonist use versus non-use among clopidogrel users or (2) PPI use versus non-use among prasugrel users or among ticagrelor users.ConclusionsOverall, our findings do not support a significant adverse clinical impact of concomitant clopidogrel/PPI use by patients with MI. Nonetheless, investigation of the possible association seen in those aged 80–89 years may be warranted.Electronic supplementary materialThe online version of this article (10.1007/s40801-020-00204-9) contains supplementary material, which is available to authorized users.

Acid-suppressive medications and risk of colorectal cancer: results from three large prospective cohort studies

BackgroundDespite several plausible biological mechanisms linking proton pump inhibitors (PPIs) and H2 receptor antagonists (H2RAs) with colorectal tumorigenesis, their association with risk of colorectal cancer (CRC) has not been adequately assessed in prospective epidemiological studies.MethodsWe evaluated the association of acid-suppressive medication use with CRC risk among 175,871 (PPI) and 208,831 (H2RA) participants from three large prospective cohort studies. Medication use was assessed at baseline and updated biennially. The association was evaluated using multivariate Cox proportional hazards regression models.ResultsThere was no significant association between baseline PPI use (hazard ratio (HR) = 0.89, 95% confidence interval (CI), 0.71–1.12) or PPI use after a lag of 8–10 years (HR = 1.12, 95% CI, 0.78–1.59) with CRC risk. We observed no significant association between H2RA use after a lag of 8–10 years and CRC risk (HR = 1.02, 95% CI, 0.81–1.28), while risk was lower for participants with baseline H2RA use (HR = 0.76, 95% CI, 0.60–0.95). Duration of PPI use or H2RA use was not associated with CRC risk (P-trend = 0.21 and 0.95, respectively).ConclusionsAmong participants from three large prospective cohorts, use of PPI or H2RA was not associated with higher risk of colorectal cancer.

Cerrahi Alan İnfeksiyonlarının Değerlendirilmesi ve Risk Faktörlerinin Analizi

Surgical site infections (SSI) extend the patient’s length of stay, causing unnecessary complications and increase mortality, morbidity and cost. In each hospital, these infections take place in hospital infection surveillance and show changes specific to hospitals. In this study, the files of 402 patients; hospitalized between 2016 and 2018 in the surgical clinics of the Health Sciences University Bursa High Specialization Training and Research Hospital were analyzed retrospectively in terms of SSI, patient profile, length of stay, underlying diseases, risk factors and causative microorganisms. In the study, patients in gynecology and obstetrics, pediatric surgery, cardiovascular surgery, orthopedics, general surgery, urology, and neurosurgery services were included in the surgeries that were followed up on the basis of the procedures in accordance with the decisions of the infection control committee. The most frequently isolated microorganisms in SSI were coagulase negative staphylococci (14.7 %) Escherichia coli (11.7 %), Staphylococcus aureus (6 %) Klebsiella spp. (7 %) and Pseudomonas spp. (3.5 %), while the rate of culture negative SSI cases was determined as (41.5 %). In statistical analysis; presence of a foreign body prosthesis, coronary artery disease, diabetes mellitus, hypertension, hemodialysis, H2 receptor antagonist use, chest tube, peripheral artery catheter, central venous catheter, nasogastric catheter, surgical drain, transfusion, urinary catheter, peripheral venous catheter, mechanical ventilation and endotracheal intubation were statistically significant in the development of SSI. In the analyzes on length of stay, it was found that the length of stay significantly increased as the depth increased in the SSI classification. Identifying risk factors for SSI is critical to reduce the incidence of SSI and identify high-risk patient populations that may require more surveillance for postoperative infection and to develop quality improvement strategies and infection control interventions.

I]Clostridioides difficile[/i] infection in patients with end stage renal disease. Is it preventable?

[i]Clostridioides difficile[/i] infection (CDI) is a leading cause of a healthcare-associated diarrhea worldwide. Recently, an increased number of new cases and growing mortality due to CDI have been observed. Patients suffering from end-stage renal disease (ESRD) are most exposed to CDI. It has been proven that CDI in patients receiving renal replacement therapy (RRT) significantly increases mortality, prolongs hospitalization and increases the cost of treatment. Important risk factors of CDI in ERSD patients include hospitalization or stay in an intensive care unit in the last 90 days, HIV infection, bacteremia, prolonged antibiotic therapy and hypoalbuminemia. Cirrhosis, age over 65 years, hypoalbuminemia, longer hospitalization time and use of antibiotics are significant risk factors of death. Effective methods of preventing CDI include hand hygiene with soap and water, isolation of infected patients in a private room with a dedicated toilet, the use of masks, gloves, disinfection of the environment and systematic education and control of medical personnel, as well as rational antibiotic policy. In addition, it is important to avoid antibiotics with a proven risk of CDI, caution use of proton pump inhibitors (PPI) and H2 receptor antagonists. It is also important in the prevention of CDI in people with ERSD, to apply a fast diagnostic since the onset of the first symptoms. The use of probiotics and bile acids in the primary prevention of CDI requires further research. It seems that knowledge of these factors and methods of prevention will significantly reduce morbidity and mortality due to CDI.

Use of Acid-Suppressant Medications After Diagnosis Increases Mortality in a Subset of Gastrointestinal Cancer Patients.

Acid-suppressant medications, including proton pump inhibitors (PPIs) and H2 receptor antagonists (H2RAs), are frequently prescribed and have been linked to increased risk of some gastrointestinal cancers. We examined whether post-diagnosis use of PPIs/H2RAs is associated with the risk of mortality in gastrointestinal cancer patients. We used data from patients with esophageal cancer, gastric cancer, or hepatocellular carcinomas (HCCs) in the national VA Central Cancer Registry diagnosed between 2002 and 2016. We identified PPI/H2RA prescriptions that were filled before and after cancer diagnosis and used time-dependent Cox regression models to calculate adjusted hazard ratios (HRs) and 95% CIs for mortality risk. We used a time-varying exposure to avoid immortal-time bias and a 3-month lag to reduce reverse causation. A sensitivity analysis was conducted varying the lag duration between the date of cancer diagnosis and the start of follow-up. PPIs were used by the majority (54% post-diagnosis use) of patients. We found no association between post-diagnosis PPI use and cancer-specific mortality in esophageal adenocarcinoma (HR 0.93; 95% CI 0.84-1.02), esophageal squamous cell carcinoma (HR 0.99; 95% CI 0.87-1.12), or gastric cardia cancer (HR 1.04; 95% CI 0.89-1.22) patients. Post-diagnosis PPI use was, however, associated with the increased risk of cancer-specific mortality for patients with gastric non-cardia cancer (HR 1.50; 95% CI 1.29-1.74) and HCC (HR 1.31; 95% CI 1.23-1.40). The results were similar for associations with post-diagnosis use of H2RAs. There was no association with pre-diagnosis PPI/H2RA use. Post-diagnosis PPI/H2RA use was associated with the increased mortality in gastric non-cardia cancer and HCC patients.
