Helicobacter pylori Burden in the United States According to Individual Demographics and Geography: A Nationwide Analysis of the Veterans Healthcare System. Clin Gastroenterol Hepatol 2024; 22:42-50.e26. [PMID: 37245717 DOI: 10.1016/j.cgh.2023.05.016] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Revised: 04/22/2023] [Accepted: 05/13/2023] [Indexed: 05/30/2023]
Abstract
BACKGROUND & AIMS There are no contemporary large-scale studies evaluating the burden of Helicobacter pylori in the United States according to detailed demographics. The primary objective was to evaluate H pylori positivity in a large national healthcare system according to individual demographics and geography. METHODS We conducted a nationwide retrospective analysis of adults in the Veterans Health Administration who completed H pylori testing between 1999 and 2018. The primary outcome was H pylori positivity overall, as well as according to zip code-level geography, race, ethnicity, age, sex, and time period. RESULTS Among 913,328 individuals (mean, 58.1 years; 90.2% male) included between 1999 and 2018, H pylori was diagnosed in 25.8%. Positivity was highest in non-Hispanic black (median, 40.2%; 95% confidence interval [CI], 40.0%-40.5%) and Hispanic (36.7%; 95% CI, 36.4%-37.1%) individuals and lowest in non-Hispanic white individuals (20.1%; 95% CI, 20.0%-20.2%). Although H pylori positivity declined in all racial and ethnic groups over the timeframe, the disproportionate burden of H pylori in non-Hispanic black and Hispanic compared with non-Hispanic white individuals persisted. Approximately 4.7% of the variation in H pylori positivity was explained by demographics, with race and ethnicity accounting for the vast majority. CONCLUSIONS The burden of H pylori is substantial in the United States among veterans. These data should (1) motivate research aimed at better understanding why marked demographic differences in H pylori burden persist so that mitigating interventions may be implemented and (2) guide resource allocation to optimize H pylori testing and eradication in high-risk groups.

Shah S, Cappell K, Sedgley R, Pelletier C, Jacob R, Bonafede M, Yadlapati R. Diagnosis and treatment patterns among patients with newly diagnosed Helicobacter pylori infection in the United States 2016-2019. Sci Rep 2023; 13:1375. [PMID: 36697470 PMCID: PMC9876904 DOI: 10.1038/s41598-023-28200-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Accepted: 01/13/2023] [Indexed: 01/27/2023] Open
Abstract
Approximately 36% of the United States (US) population is infected with Helicobacter pylori (HP), a known major risk factor for peptic ulcer disease and gastric cancer. HP eradication reduces the rate of complications; however, the benefits are undermined by rising rates of HP eradication treatment failure. This real-world observational cohort analysis aims to describe HP diagnostic and treatment patterns among insured patients in the US. Using diagnoses, lab results, and treatment patterns, we identified adults (18+) with new diagnoses of HP in the Veradigm Health Insights EHR Database linked to Komodo claims data (1/1/2016-12/31/2019). Patients were required to have ≥ 12 months of data pre-/post-index. We captured patient characteristics, HP-related diagnostic testing, and the use of US guideline-recommended HP eradication regimens. HP eradication rates following first-line eradication treatment were measured among patients with available lab results. Overall, 31.8% of the 60,593 included patients did not receive guideline-recommended treatment. Among the 68.2% (41,340) with first-line treatment, 80.2% received clarithromycin-based triple therapy, and 6.6% received bismuth quadruple therapy. Of the 4569 patients with a repeated course of eradication therapy, 53.4% received the same regimen as their first-line, the majority (90.7%) of whom received two rounds of clarithromycin-based triple therapy. Among the 2455 patients with results of HP non-serology testing following first-line treatment, the 180-day eradication rate was 80.2% overall, with differences based on treatments and demographics. This study highlights gaps between guideline-recommended HP management and real-world patterns, underscoring the need to improve HP testing, treatment, and follow-up practices.

A Population-Based Cross-sectional Study on the Prevalence and Associated Risk Factors of Helicobacter pylori Infection in Rafsanjan, a Low Gastric Cancer Area in Southeast Iran. Middle East J Dig Dis 2022; 14:287-293. [PMID: 36619268 PMCID: PMC9489427 DOI: 10.34172/mejdd.2022.285] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Accepted: 06/10/2022] [Indexed: 11/06/2022] Open
Abstract
Background: Despite all improvements in sanitation and exposure to antibiotics over time, Helicobacter pylori (HP) prevalence remains high, affecting the lives of about half of the world population, which can gradually lead to serious upper gastrointestinal disorders. Understanding HP's epidemiologic patterns help us to better manage the burden of this infection and to plan more effectively regarding potential screening or eradication strategies. We, therefore, aimed to report the crude and age- and sex-standardized prevalence rate of HP infection, its trend, and possible associated factors among asymptomatic healthy individuals in Rafsanjan city, a low-incidence area of gastric cancer (GC) in the southeast of Iran, from July 2018 to December 2021. Methods: This population-based cross-sectional descriptive study included 2,046 male and female subjects between 3 to 72 years who were in good health condition. Study participants were randomly selected from the Health Houses and each underwent a questionnaire-based interview and provided blood and feces samples. The presence of HP infection was detected by serum IgG antibodies and stool antigen test. Results: The overall and age- and sex-standardized prevalence rates of HP infection were 50.9% and 43%, respectively. The prevalence rate has notably decreased in all age groups compared with 2007. Also, it was significantly higher among men (P=0.033) and increased with advancing age (P<0.001). A higher population density living in a specific room area (P=0.012) increased the likelihood of HP infection. Conclusion: To conclude, the prevalence of HP infection is decreasing over time in Rafsanjan city, which may be due to improvements in living standards in this area. A healthy lifestyle and adherence to hygienic principles, especially during childhood, may be required for a reduction in the prevalence of HP infection.

Nativity Status is an Important Social Determinant of Health for Hispanic Patients with Gastric Cancer in Texas. Ann Surg Oncol 2022; 29:3113-3121. [PMID: 35028796 DOI: 10.1245/s10434-021-11188-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2021] [Accepted: 11/21/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND The U.S. foreign-born population is rapidly increasing, and cancer incidence/mortality rates have been shown to differ by nativity status. Our study aimed to characterize differences in gastric cancer presentation and survival among Hispanic patients in Texas by nativity status. METHODS We conducted a retrospective review of the Texas Cancer Registry to identify Hispanic patients diagnosed with gastric adenocarcinoma between 2004 and 2017. Existing indices applied to 2010 census tract-level data were utilized to measure neighborhood socioeconomic status (nSES) and Hispanic enclaves. Nativity status was imputed for patients with missing data. Multivariable Cox proportional hazard models were fit for overall survival adjusted for age, insurance status, diagnosis year, tumor location, stage, grade, reporting source, nativity status, nSES, and Hispanic enclave. RESULTS Our study cohort consisted of 6186 patients and 39% were foreign-born. A greater proportion of foreign-born patients were diagnosed at < 45 years old (16% vs. 11%, p < 0.0001) and had metastatic disease at presentation (47% vs. 34%, p < 0.0001). Foreign-born patients were more often uninsured, in the lowest nSES quintile, and the highest (most ethnically distinct) quintile for Hispanic enclave. Stage-specific overall survival was significantly higher among foreign-born patients. In our multivariate model, foreign-born Hispanic patients had improved survival versus US-born (hazard ratio [HR] 0.90, 95% confidence interval [CI] 0.82-0.99). CONCLUSIONS The clinical presentation of gastric cancer differs significantly between foreign-born and U.S.-born Hispanic patients. Foreign-born Hispanic patients have improved survival after adjusting for socioeconomic, neighborhood, and clinical factors. Further studies are needed to identify specific causal mechanisms driving the observed survival difference by nativity status.

Associations of Helicobacter pylori and hepatitis A seropositivity with asthma in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL): addressing the hygiene hypothesis. Allergy Asthma Clin Immunol 2021; 17:120. [PMID: 34819160 PMCID: PMC8611872 DOI: 10.1186/s13223-021-00625-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Accepted: 11/08/2021] [Indexed: 11/10/2022] Open
Abstract
Abstract
Background
The hygiene hypothesis posits that microbial exposure reduces risk of asthma and other respiratory-related diseases. Helicobacter pylori and hepatitis A virus (HAV) are common fecal–oral infections. Our study aimed to examine associations of seropositivity to these agents with asthma in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL).
Methods
A total of 12,471 HCHS/SOL participants with baseline data on self-reported physician-diagnosed asthma, and antibodies anti-H. pylori and anti-HAV were included in this cross-sectional analysis. Multivariable logistic regression models were used to estimate the odds ratios and 95% confidence intervals for the overall associations of seropositivity to each agent with asthma. Analyses were also stratified by Hispanic/Latino background. Effect modification by smoking status and nativity were tested. An analysis restricted to individuals with spirometry-defined chronic obstructive pulmonary disease (COPD) was also considered.
Results
The weighted overall prevalence of asthma was 16.6%. The weighted seroprevalence of H. pylori was 56.6% and of HAV was 76.6%, and they significantly differed by Hispanic/Latino background. After accounting for age, sex, education and other key confounders, we found no associations between H. pylori or HAV seropositivity with asthma (with and without COPD), either for all individuals combined or for any of the six specific backgrounds. There were no significant interactions by smoking and nativity.
Conclusion
Our findings did not provide support for the role of H. pylori or HAV, as evidence of the hygiene hypothesis in asthma among the large and diverse Hispanic/Latino populations of the HCHS/SOL.
