Abstract
Inflammation may play contradictory roles in the pathogenesis of gastroesophageal reflux disease (GERD): gastritis decreases gastric output and reduces the risk of esophagitis, while interleukins may favor mucosal inflammation. The inflammation may cause esogastric motility changes and thus increase the risk of esophagitis. Considering the genetic influence of inflammatory response, we looked for the genetic polymorphisms of IL-1 in GERD manifested as reflux esophagitis. This is a prospective study carried out in GERD and healthy controls. We assessed in these groups the following single nucleotide polymorphisms (SNPs): IL-1A (rs1800587), IL-1B (rs16944), IL-1B (rs1143634) and the VNTR for IL-1RN. Both groups were similar according to biographical data. Reflux esophagitis was confirmed by endoscopy and where necessary by pH-impedance monitoring. Reflux esophagitis was associated only with the polymorphism rs16944. No other correlations with the other three genetic polymorphisms were detected. These data suggest that the diverging effects of proinflammatory factors on the upper digestive tract may have deleterious effect on GERD. The IL-1B (rs16944) SNP correlates with reflux esophagitis.

The Influence of IL-1B Gene Polymorphisms on H. pylori Infection and Triple Treatment Response Among Jordanian Population. APPLICATION OF CLINICAL GENETICS 2020; 13:139-145.

Abstract
Background Helicobacter pylori (H. pylori) is considered the main cause of gastritis, peptic ulcer and gastric carcinoma in the human populations. H. pylori infection influences the secretion level of several proinflammatory cytokines including IL-1β, which encoded by the IL-1B gene. Objective The current study aimed to investigate whether IL-1B gene polymorphisms are associated with H. pylori infection among the Jordanian population and responses to triple therapy. Subjects and Methods The gastroscopic examination was performed on 412 subjects for H. pylori infection diagnosis, 257 subjects were found to be infected by H. Pylori (positive cases), whereas 155 subjects were uninfected (negative controls). The IL-1B gene T-31C and C3954T polymorphisms were genotyped by PCR-RFLP. Results It was found that the T-31C polymorphism has a significant association with H. pylori infection (P<0.05), and the TT genotype frequency was significantly higher in infected subjects (50.2%) compared to controls (38.7%). On the other hand, no significant association was detected between C3954T SNPs and H. pylori infection among the Jordanian population. In addition, none of the examined polymorphisms were found to influence the responses to triple therapy. Conclusion The IL-1B gene T-31C SNP might be associated with an enhanced risk of H. pylori infection among the Jordanian population.

Abstract
Objective: The aim of study was to investigate the association of IL 1B gene polymorphism with involvement of H. pylori and other gastric diseases. Methods: Blood samples of dyspeptic patients were collected from endoscopy department of Allied Hospital Faisalabad from January 2017 to January 2019 and were qualitatively assayed for serological detection of CagA H. pylori antibodies. PCR followed by direct sequencing was performed for proinflammatory IL-1B gene polymorphism detection. Sequence analysis was performed in software SnapGene viewer for haplotypes. Results: Demographic characteristics of seropositive patients showed maximum 25% gastritis in age groups of 20-40 years and 41-60 years, predominantly (41.7%) in females. While in seronegative patient’s gastritis (33.3%) was found in age group of 20-40 years mainly in males (41.7%). Among studied groups, higher expression of IL-1B-511 genotype (33.3%) polymorphism was found in healthy individuals as compared to H. pylori seropositive (25%) and seronegative (8.3%). While IL-1B-31 genotype showed maximum 33.3% polymorphism rate in seropositive gastric diseased group. Moreover, haplotypes frequencies IL-1B-511CC and IL-1B-31TT were predominantly (20%) found in seropositive gastric diseased group. Conclusions: In H. pylori seropositive patients, gastric disease was commonly found, however, gastric disease was not only associated with H. pylori as seronegative patients were also carrying gastric complications. Interleukin IL-1B polymorphism was partially associated with H. pylori infection in studied dyspeptic population.

Abstract
The clinical outcome of infection with the chronic gastric pathogen Helicobacter pylori is not the same for all individuals and also differs in different ethnic groups. Infection occurs in early life (<3 years of age), and while all infected persons mount an immune response and develop gastritis, the majority of individuals are asymptomatic. However, up to 10-15% develop duodenal ulceration, up to 1% develop gastric cancer (GC) and up to 0.1% can develop gastric mucosa-associated lymphoid tissue (MALT) lymphoma. The initial immune response fails to clear infection and H. pylori can persist for decades. H. pylori has been classified as a group one carcinogen by the WHO. Interestingly, development of duodenal ulceration protects against GC. Factors that determine the outcome of infection include the genotype of the infecting strains and the environment. Host genetic polymorphisms have also been identified as factors that play a role in mediating the clinical outcome of infection. Several studies present compelling evidence that polymorphisms in genes involved in the immune response such as pro and anti-inflammatory cytokines and pathogen recognition receptors (PRRs) play a role in modulating disease outcome. However, as the number of studies grows emerging confounding factors are small sample size and lack of appropriate controls, lack of consideration of environmental and bacterial factors and ethnicity of the population. This chapter is a review of current evidence that host genetic polymorphisms play a role in mediating persistent H. pylori infection and the consequences of the subsequent inflammatory response.

Abstract
Background/Aims Gastric juice plays a crucial role in the physiology of the stomach. The aim of this study is to evaluate associations among the pH of gastric juice, atrophic gastritis (AG), intestinal metaplasia (IM), pepsinogen, and Helicobacter pylori infection. Methods Gastric biopsies and juice were collected from 46 subjects who underwent endoscopies at Seoul National University Bundang Hospital between November 2011 and March 2013. H. pylori, AG and IM were evaluated, and pepsinogen I or II, I/II ratio, and interleukin (IL)-1β levels were measured. Results The mean pH of gastric juice was higher in the H. pylori-positive group (n=17) than that in the H. pylori-negative group (n=29) (4.54 vs 2.46, p=0.002). When patients were divided into pH <3 (n=28) and pH ≥3 (n=18) groups, H. pylori was lower in the pH <3 group (21.4%) than in the pH ≥3 group (61.1%) (p=0.007). The pH ≥3 group demonstrated AG and IM more frequently than the pH <3 group in the body (p=0.047 and p=0.051, respectively) but not in the antrum. There were no differences in pepsinogen I or II, I/II ratio, and IL-1β levels between the two groups. Conclusions There is a relationship between chronic H. pylori infection and gastric juice pH ≥3, which may originate from AG and IM in the body.

Abstract
Helicobacter pylori infection, a common infection in many countries, is related to the clinical course of upper gastrointestinal diseases. Gastroesophageal reflux disease (GERD) is a common esophageal disease in Western countries and its prevalence is increasing in Asian countries. The pathophysiology of GERD is multifactorial. Although no single factor has been isolated as the cause of GERD, a negative association between the prevalence of H. pylori and the severity of GERD, including Barrett's esophagus, has been demonstrated in epidemiological studies. The high prevalence of H. pylori infection affects the incidence of GERD in Asian countries. In the subjects with East Asian CagA-positive strains, acid injury may be minimized by hypochlorhydria from pangastritis and gastric atrophy. Additionally, host genetic factors may affect the development of GERD. The interactions between genetic factors and the virulence of H. pylori infection may be the reason for the low prevalence of GERD in Asian countries. H. pylori eradication is not considered pivotal in GERD exacerbation based on evidence from Western studies. A recent meta-analysis demonstrated that eradication therapy of H. pylori was related to a higher risk of developing de novo GERD in Asian studies. H. pylori infection remains an inconclusive and important issue in GERD in Asian countries.
