Prevalence of Helicobacter pylori in Southern Part of Iran

Abstract

Background: There are clear variations between and within countries regarding the prevalence of Helicobacter pylori. In addition, there are no estimations of its prevalence in the general population in the south of Iran. Objectives: We aimed to evaluate the prevalence of H. pylori in the rural population of Kavar, a southern city of Iran. Methods: A random sample of 500 individuals were selected from the Kavar cohort study. Serum total IgG against H. pylori was checked. The serum positive patients recalled for stool sampling and the H. pylori stool antigen was checked using sandwich ELISA. Moreover, age and gender were recorded for all patients. Results: Among the remained 441 who participated, 254 patients (57.6%) were positive for serum IgG. A total of 14 patients (5.5%) gave up due to stool sampling unsatisfaction. Overall, the rate of H. pylori infection based on both serum IgG and stool Ag of H.

Incidence Trends of Gastric Cancer in Southern Iran: Adenocarcinoma and Non-cardia Gastric Cancer Are More Rising Among Younger Ages

“…( 14) It also maybe because of very low and stable population exposure to H. pylori in this region. (20) This nding is inconsistent with previous reports from developed countries, which showed a decreasing trend for the incidence of GC. (22,23)However, this could be considered as a starting point for the signi cant decrease in the incidence of GC in this region.…”

“…(17,18) It may be due to higher socio-development, lower prevalence of Helicobacter pylori, and higher healthcare coverage in this region compared with other regions. (19)(20)(21) Our results showed that the overall trend of ASRs of GC has been stable from 2009 to 2015. According to the joinpoint regression, the last observed trends had been started in 2009.…”

Determination of Helicobacter Pylori Infection Prevalence by Non-invasive Methods

“…According to the results of this study, the seropositivity against H. pylori using ELISA kit for IgG, IgM, and IgA antibodies was 53.1%, 1.1%, and 0.2%, respectively. Some researchers reported 57.6% and 60.5% rates for IgG (35,36) that are in agreement with our results, while others reported 72.9%, 60%, and 21.2% rates which are inconsistent with our findings (29,37,38). The results of IgA were consistent with an earlier study which was 2.64% (39).…”

The Prevalence of Helicobacter pylori Infections in Duhok Province, Iraq: A Retrospective Study

“…Furthermore, our results nearly similar in the prevalence of infections age groups whereas by contrast the results are disagree in the rates of infections in males and females some Iraqi studies, where in our results the rate of males higher than females, but in study of Albadri [25] and the study of Majeed & Khoshnaw [26] the rates of infections were higher in females than males. In the final analysis, these differences among the rates of infections in males and females may as a result of the effect of socioeconomic situations, the geographical area, the level of education and the life style according to many research in the developing and developed countries, as exemplified by the research of Ozaydin et al [27], Eshraghian [28], Alsulaimany et al [29], Balas et al [30], Niknam et al [31], (Khoder et al [32], Alfaray et al [33]. In the current study, the small size and shortage of the data with lack of other socioeconomic factors may affect the accuracy and outcome of the findings.…”
