“…Host iron is known to be essential for pathogen growth [17]. However, there have been inconsistent reports on the roles of iron in the acquisition of H. pylori infection [17][18][19]. Perhaps, the iron overload in thalassemia patients might have contributed to the high prevalence of H. pylori infection observed in our study.…”

“…In the remaining seventeen studies, two reviews 14, 21 and eight publications not being case-control design 22-29 were discarded. Then, a total of seven case-control studies were identified, of which two studies not presenting detailed raw data were further excluded 30, 31. Finally, five case-control studies were included in this study 32-36.…”

Objective: Helicobacter pylori (H. pylori) infection has been thought to play a critical role in disorders such as gastric and lung cancer. A number of studies have been devoted to the relationship between H. pylori infection and asthma risk, which have generated inconclusive results. In this study we aimed to derive a more precise estimation of the relationship.Methods: Meta-analyses evaluating the association of H. pylori infection and asthma risk were conducted and subgroup analyses on ethnicity and source of controls as well as CagA status were further conducted. Eligible studies were identified for the period up to Jul 2012.Results: A total of five case-control studies comprising 770 cases and 785 controls were lastly selected for analysis. The overall data failed to indicate a significant association of H. pylori infection and asthma risk (OR=1.01; 95%CI=0.82-1.24). Likewise, in the subgroup analysis regarding ethnicity, source of controls and CagA status, no associations could be observed.Conclusions: The pooled data failed to suggest a marked association between H. pylori infection and asthma risk. Future studies are needed to confirm this conclusion.

“…In a different study the same authors found that colo- In Jeddah, Saudi Arabia, 1432 children; were tested for H. pylori status by ELISA using IgG antibodies (HM-CAP; Enteric Products Incorporation, Westbury, NY). The prevalence did not differ according to nationality and gender but significantly increased with age in children with chronic asthma, chronic anemia and neurological impairment (P < 0.01 for all), length of illness, number of blood transfusions, number of hospital admission and type of feeding (14).…”

Background: It has been suggested that Helicobacter pylori infection might reduce the risk of atopic conditions, such as asthma, in childhood. This risk reduction could relate to the "hygiene hypothesis" which proposes an association between childhood exposure to microbes and risk of atopy. Objectives: To examine the association between Hp infection and childhood acquired asthma in Sardinia. Patients and Methods:Children from Northern Sardinia who were between the ages of 10 months to 6 years and were screened for Hp infection in 1994-1995 using IgG serology, were asked in 2012, whether they had developed asthma and/or allergic disease in pediatric age, using the global initiative on asthma guidelines questionnaire. Results: A total of 64 children participated in the study. The sero-positivity for Hp infection was 14.1%. Eleven (17.2%) children had a confirmed diagnosis of asthma with onset before the age of 5 years, 85.9% were Hp negative and 14.1% Hp positive. Eight children of the 53 without asthma were Hp positive (15%) compare to one children positive for the infection of the 11 patients (0.09%) with asthma (8/53 vs. 1/11; P = 0.6). The majority of children (73%) were from urban areas and 43.8% had a family history of asthma or allergies. Multiple logistic regression analysis was not able to find a studied variable, including Hp infection, significantly associated with pediatric asthma. Conclusions: Our results speak against Hp infection itself playing a role to protect from the risk to develop childhood asthma although household hygiene was not directly assessed.
