| خلاصه مقاله | BACKGROUND AND OBJECTIVES
Helicobacter pylori (H. pylori) is a widespread pathogenic agent that often invades gastric
mucosa epithelial cells. Invasion of this dominant bacterial species of stomach can induce
mucosal cellular immunity and local and systemic humoral immunity. Hence, it is possible to
identify common H. pylori infection by assessing host immune responses as a non-invasive
method. In this research we aimed to detect the abundance of serum immunoglobulin (Ig) G,
IgM and IgA and their association with the age and gender of participents from children to
adults in Tabriz, Iran.
MATERIALS AND METHODS
Between 2019-2022, venous serum samples of 3733 normal participants (1235 males, 2498
females) were collected for immunodiagnosis of H pylori infection. The enzyme-linked
immunosorbent assay method was used to detect the antibody groups. The statistical data was
analyzed by SPSS software.
RESULTS AND DISCUSSION
According to comparison results, the prevalence of IgG in 1949 individuals (57.9%), IgA in
83 individuals (11.6%), and IgM in 8 (0.3%) participants were reported positive. In terms of
seropositivity, females were the significant target group for only IgM. While for both IgA and
IgG, the number of seropositive males was predominant with a non-significant difference.
Moreover, a significant correlation was observed between ageing and positive prevalence of
IgG, IgM and IgA antibodies in biosamples. In some age subgroups, gender was also a
remarkable factor for evaluating the prevalence of serum indicators such as IgG and IgM.
CONCLUSION
Similar to most cities in Iran, there is an unstable situation in the capital of East Azerbaijan
province against H. pylori infection. Out of three immunoglobulin groups, IgG had the
highest serum prevalence among our study population. Also, adult age groups were more at
risk of H. pylori infection. Due to the growing prevalence of this pathogen, it is necessary to
pay attention to infection control programs of developed countries and promoting basic
health education. |
