Abstract
The genomic characteristics of Peruvian patients with gastric adenocarcinoma from diverse socioeconomic backgrounds were examined in consideration of the possibility that patients from different socioeconomic backgrounds may be exposed to different risk factors. We conducted a prospective pilot study in two Peruvian cities (Lima and Ica). This study enrolled 15 patients from low socioeconomic status (LSES) and 15 patients from medium/high socioeconomic status (MHSES). The genomic profiling of gastric adenocarcinoma samples was done through the FoundationOne CDx platform. We compared the genomic characteristics and the need for targeted therapy and immunotherapy between LSES and MHSES. The genes with higher rates of alterations were TP53 (73.3% vs. 50.0%, P = 0.2635); CDH1 (26.7% vs. 28.6%, P = 1); CDKN2A (20.0% vs. 28.6%, P = 1); KRAS (33.3% vs. 7.1%, P = 0.1686); ARID1A (20.0% vs. 14.3%, P = 1); MLL2 (13.3% vs. 21.4%, P = 1) and SOX9 (33.3% vs. 0.0%, P = 0.0421) in LSES versus HMSES, respectively. There was no significant difference in tumor mutational burden (P = 0.377) or microsatellite status (P = 1). The LSES group had a higher need for targeted therapy or immunotherapy according to gene involvement and alterations. A significant genomic difference exists among patients with gastric adenocarcinoma of different socioeconomic status, which may result in a different need for targeted therapy and immunotherapy.

[PMID: 38966320 PMCID: PMC11221896 DOI: 10.1055/a-2297-9905] [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: 10/12/2023] [Accepted: 03/22/2024] [Indexed: 07/06/2024] Open
Abstract
Background and study aims Socioeconomic deprivation has long been associated with many gastrointestinal diseases, yet its influence on esophagogastroduodenoscopy (EGD) diagnosis has not been evaluated. The aim of this study was to investigate the influence of deprivation on outcomes of EGD irrespective of referral reason. Patients and methods Two thousand consecutive patients presenting to four Health Boards in Wales beginning in June 2019 were studied retrospectively with deprivation scores calculated using the Wales Indices of Multiple Deprivation (WIMD). Patients were subclassified into quintiles for analysis (Q1 most, Q5 least deprived). Results Inhabitants of the most deprived areas were more likely to be diagnosed with peptic ulcer (Q1 7.9%, Q5 4.7%; odds ratio [OR] 0.498, P =0.018), severe esophagitis (LA4, Q1 2.7% v Q5 0%, OR 0.089, P 0.002), Helicobacter pylori infection (Q1 5.4%, Q5 1.7%; OR 0.284, P =0.002), but less likely to be diagnosed with Barrett's esophagus (Q1 6.3% v Q5 12.3%, OR 2.146, P =0.004) than those from the least deprived areas. New cancer diagnoses numbered 53 and were proportionately higher after presentation for urgent suspected cancer (USC, n=35, 4.6%) than for routine referrals (n=3, 0.6%, P < 0.001). Deprivation was associated with more advanced stage cancer (stage III Q1 16.7% v Q5 5.6%, OR 0.997, P =0.006: stage IV Q1 16.7% v Q2 38.9% v Q5 22.2%, OR 0.998, P =0.049). Conclusions Deprivation was associated with two-fold more peptic ulcer disease, three-fold more H. pylori infection, and 12-fold more severe esophagitis, and more advanced cancer stage.

Sero- and Feco-Prevalence of Helicobacter pylori Infection and Its Associated Risk Factors among Adult Dyspeptic Patients Visiting the Outpatient Department of Adet Primary Hospital, Yilmana Densa District, Northwest Ethiopia. THE CANADIAN JOURNAL OF INFECTIOUS DISEASES & MEDICAL MICROBIOLOGY = JOURNAL CANADIEN DES MALADIES INFECTIEUSES ET DE LA MICROBIOLOGIE MEDICALE 2023; 2023:2305681. [PMID: 37492856 PMCID: PMC10365919 DOI: 10.1155/2023/2305681] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Revised: 06/11/2023] [Accepted: 07/05/2023] [Indexed: 07/27/2023]
Abstract
Background Most gastric cancers in the world are attributed to Helicobacter pylori (H. pylori) infections. The prevalence of H. pylori infection is influenced by socioeconomic status, hygiene, and lifestyle of the population. This study aimed to assess sero- and feco-prevalence of H. pylori infections and its associated risk factors among adult dyspeptic patients visiting the outpatient department of Adet Primary Hospital, Yilmana Densa District, northwest Ethiopia. Methods A hospital-based cross-sectional study was conducted from February 10, 2022 to April 10, 2022. The study participants were selected using a systematic random sampling technique. The data were collected by pretested questionnaires. Blood and stool specimens were collected from each patient for antibody and H. pylori antigen tests, respectively. The data were analyzed using Statistical Package for Social Science (SPSS) version 26.0. A logistic regression model was used to assess the strength of association between H. pylori positivity and risk factors. Results The sero- and feco-prevalence of H. pylori infection was 62% and 51.1%, respectively. In those patients who had a positive result with either the antibody (Ab) or antigen (Ag) test, rural residence (AOR = 5.55; 95% CI: 2.34-13.14; p < 0.001), alcohol consumption (AOR = 12.34; 95% CI: 2.29-66.51; p=0.003), having no awareness about H. pylori transmission (AOR = 4.76; 95% CI: 1.86-12.15; p=0.001), using pond/river as a source of drinking water (AOR = 5.22; 95% CI: 1.91-14.27; p=0.001), and open field defecation (AOR = 4.19; 95% CI: 1.67-10.52; p=0.002) were the explanatory risk factors significantly associated with H. pylori infection. Conclusion This study showed that the prevalence of H. pylori infection was very high. Most cases of gastric cancers are ascribed to H. pylori infection. Therefore, education should be given to communities so as to increase their awareness of the infection and the associated major explanatory risk factors identified in the present study.

Expression Assessment of the Helicobacter pyloribabA and sabA Genes in Patients with Peptic Ulcer, Duodenal Ulcer and Gastric Cancer. INTERNATIONAL JOURNAL OF MOLECULAR AND CELLULAR MEDICINE 2023; 12:211-219. [PMID: 38313370 PMCID: PMC10837913 DOI: 10.22088/ijmcm.bums.12.2.211] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Revised: 10/04/2023] [Accepted: 11/25/2023] [Indexed: 02/06/2024]
Abstract
Helicobacter pylori as a common gastrointestinal (GI) pathogen must possess certain virulence characteristics to colonize the stomach, evade host immune responses, and subsequently induce GI diseases. This research aimed to investigate the expression level of two important genes, the sialic acid-binding adherence (SabA) and the blood group antigen-binding adhesion (BabA) in H. pylori strains isolated from adult patients living in the northern part of Iran, and their association with peptic ulcer disease (PUD) and gastric cancer (GC). This cross-sectional study was carried out on adult patients referring to the GI clinic of the hospitals affiliated to Babol University of Medical Sciences, Iran. New cases diagnosed with gastritis, peptic ulcer or gastric cancer were included. Endoscopic-guided gastric biopsies were examined and H. pylori positive colonies were analyzed to determine the expression of babA and sabA genes, utilizing specific primers and the SYBR Green dye. Among 175 patients with mean age of 51.6±15.6 years, 101 (57.7%) of the individuals tested positive for H. pylori infection. Statistical analysis revealed a significant correlation between sabA (P=0.003) and babA (P=0.002) gene expression and development of PUD and GC. Smoking (P=0.052), gender (P=0.004) and positive babA gene expression (P=0.009) had the greatest association with occurrence of PUD or GC in H. pylori positive patients. In summary, the presence of the sabA gene in people infected with H. pylori increased the risk of GC compared to gastritis, while, the presence of the babA gene was significantly increased in gastric ulcer patients. Considering the diversity of H. pylori isolates and the varying results observed in different geographical regions, further comprehensive studies are required to evaluate the function of these genes in H. pylori pathogenesis and their relationship with clinical outcomes.
