Association of Interleukin-1B gene Polymorphism with H. pylori infected Dyspeptic Gastric Diseases and Healthy Population
H. pylori infected Dyspeptic Gastric Diseases
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.
