Assessment of Helicobacter pylori cytotoxin-associated Gene A (Cag A) protein and its association with ferritin and vitamin B12 deficiencies among adult healthy asymptomatic residents in Sharjah, United Arab Emirates. Heliyon 2024; 10:e32141. [PMID: 38882276 PMCID: PMC11180313 DOI: 10.1016/j.heliyon.2024.e32141] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2024] [Revised: 05/28/2024] [Accepted: 05/29/2024] [Indexed: 06/18/2024] Open
Abstract
The United Arab Emirates (UAE) serves as an effective epidemiological site for assessing Helicobacter pylori (H. pylori) infection due to its diverse population. However, comprehensive studies on the prevalence of H. pylori in the UAE are notably scarce. In depth prevalence studies are needed as a preventive measure against gastric cancer and other emerging extra gastric diseases associated with H. pylori infection. Aim: This study aimed to assess H. pylori infection and its virulent oncoprotein, the Cytotoxin-Associated Gene (Cag A) and its association with ferritin and vitamin B12 deficiencies. Methods: The study was conducted on 1094 healthy asymptomatic volunteers residents in the Sharjah Emirate, UAE. Enzyme-linked immunosorbent assay (ELISA) was performed to assess H. pylori infection using H. pylori antibodies (IgG), and detection of CagA protein using Cag A antibody (IgG) in the human serum. Ferritin and vitamin B12 serum levels were assessed and correlated to H. pylori infection. Results: This study focuses mainly on the assessment of H. pylori and its virulent factor CagA, in relation to vitamin B12 and ferritin deficiencies. Remarkably, 49.6 % of the participants were detected positive for H. pylori, with over half of these cases involving CagA positive strains. Notably, among Emirati participants, 76.11 % of those with H. pylori infection were CagA positive. Statistical analysis revealed a significant correlation between H. pylori, CagA level, and ferritin/vitamin B12 deficiencies. Conclusion: These findings emphasize the importance of timely detection and eradication of H. pylori not only as a preventive strategy against gastric cancer but also as an effective strategy to rescue the adverse effects from ferritin and vitamin B12 deficiencies, thereby improving the overall health outcomes of individuals affected by H. pylori infection.

[PMID: 30836932 PMCID: PMC6402101 DOI: 10.1186/s12879-019-3849-y] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2018] [Accepted: 02/25/2019] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND The prevalence of Helicobacter pylori (H. pylori) infection increases with age. However, the relationship between H. pylori infection and anemia in the elderly population remains to be identified. The aim of this study is to explore whether H. pylori infection is associated with anemia in a male elderly cohort. METHODS A cross-sectional study was designed using data collected from asymptomatic male senior citizens (≥ 65 years old) who received an assessment of their health status at the General Hospital of Chinese PLA from January 2015 to December 2015. H. pylori infection was confirmed by the 13C-urea breath test. Blood samples from the participants were taken to assay for hemoglobin and other erythroid-related indices - serum iron, ferritin, and C-reactive protein (CRP). Anemia was defined as hemoglobin values lower than 120.0 g/L. Charlson Comorbidity Index (CCI) was applied to establish baseline comorbidities. RESULTS Data from 646 subjects were analyzed. The mean age of the study cohort was 79.4 ± 8.9 years. The overall prevalence of H. pylori infection was 35.3%. The prevalence of anemia in the H. pylori positive group was higher than that in the negative group (5.3% vs. 2.2%, P = .033). Among the patients who had higher CCI scores (> 2), the prevalence of anemia in the H. pylori positive and negative groups were 10.3 and 1.4%, respectively (P = .009). Compared to the H. pylori negative group, the odds ratio for anemia of the H. pylori positive group was 2.53 (P = .033). No correlation between H. pylori infection and serum iron and ferritin levels was found. The mean corpuscular volume of the H. pylori positive and negative group was 91.17 ± 3.94 fl and 91.17 ± 4.09 fl (mean ± SD), respectively (P = .986). The CRP level in the H. pylori positive group was higher than that in the H. pylori negative group (Median: 0.17 mg/dL vs. 0.10 mg/dL, P < .001). CONCLUSION H. pylori infection seems to be associated with normocytic and normochromic anemia in elderly males, especially in those with more comorbidities. Further clinical studies are needed to verify the association.

Abstract
The role of Helicobacter pylori (H. pylori) infection in haematological system diseases is not well understood. We conducted this retrospective study to explore the association between H. pylori infection and anaemia in the Chinese population. This retrospective study was performed in Aerospace Center Hospital in Beijing. We derived the data from the registration system of the physical population between 2012-2016. Logistic regression models were used to explore the association between H. pylori infection and anaemia. Among 17,791 subjects, there were 7,804 (43.9%) subjects with H. pylori infection and 950 (5.3%) with anaemia. The prevalence of anaemia in the H. pylori (+) group was significantly higher than in the H. pylori (-) group after adjusting for age, sex, marriage, underlying diseases and body mass index. Compared to H. pylori (-), the OR of H. pylori (+) was 1.39 for moderate-to-severe anaemia and 1.05 for mild anaemia. The level of haemoglobin was lower in the H. pylori (+) group than in the H. pylori (-) group. This study indicates that H. pylori infection may be related to anaemia and haemoglobin level in the Chinese population.

Abstract
BACKGROUND We conducted an updated systematic review and meta-analysis to examine the prevalence of depleted iron stores among persons infected with Helicobacter pylori compared to uninfected ones. We also assessed the impact of anti-H. pylori eradication therapy plus iron therapy on ferritin and hemoglobin levels compared to iron therapy alone. METHODS A literature search was conducted using the databases Medline, the Cochrane Library, Cochrane Central Register of Controlled Trials, EMBASE, and the Science Citation Index Expanded. Observational studies with methodological quality score of 13 (median score) and above, on a scale of 0-16, and all randomized controlled trials (RCTs) were eligible for the meta-analyses. Pooled point estimates and 95% confidence intervals (CI) were obtained using the random effects model. RESULTS Compared to uninfected persons, H. pylori-infected individuals showed increased likelihood of iron deficiency anemia (14 observational studies); pooled OR 1.72 (95% CI 1.23-2.42); iron deficiency (pooled OR 1.33; 95% CI 1.15-1.54; 30 studies); and anemia (pooled OR 1.15; 95% CI 1.00-1.32; 23 studies). Meta-analyses of seven RCTs showed increased ferritin, standardized mean difference (SMD) 0.53 (95% 0.21-0.85), but not hemoglobin, SMD 0.36 (95% -0.07 to 0.78), Pv=.1, following anti-H. pylori eradication therapy plus iron therapy as compared with iron therapy alone. Significant heterogeneity was found among studies, as well as evidence of publication bias. CONCLUSIONS Current evidence indicates increased likelihood of depleted iron stores in relation to H. pylori infection. H. pylori eradication therapy, added to iron therapy, might be beneficial in increasing ferritin and hemoglobin levels.

The Association of Helicobacter pylori Eradication with the Occurrences of Chronic Kidney Diseases in Patients with Peptic Ulcer Diseases. PLoS One 2016; 11:e0164824. [PMID: 27764171 PMCID: PMC5072588 DOI: 10.1371/journal.pone.0164824] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2016] [Accepted: 09/30/2016] [Indexed: 02/06/2023] Open
Abstract
The association of Helicobacter pylori eradication with the occurrence of renal dysfunction in patients with peptic ulcer diseases is still unclear. This study aimed to clarify the relevance of H. pylori eradication to the occurrence of chronic kidney diseases in patients with peptic ulcer diseases. Data that were available from 2000–2011 were extracted from the National Health Insurance Research Database in Taiwan, and all patients with peptic ulcer diseases (n = 208 196) were screened for eligibility. We divided randomly selected patients into an H. pylori eradication cohort (cohort A, n = 3593) and matched them by age and sex to a without H. pylori eradication cohort (cohort B, n = 3593). Subgroup analysis was further performed for H. pylori eradication within ≤ 90 days of the diagnosis date (early eradication, n = 2837) and within 91–365 days (non-early eradication, n = 756). Cox proportional hazards regression analysis was used to estimate the association of H. pylori eradication with the risk of developing chronic kidney diseases and mortality. We observed that there were more patients suffering from chronic kidney disease in cohort B than in the early eradication subgroup of cohort A (8.49% vs. 6.70%, respectively, p = 0.0075); the mortality rate was also higher in cohort B (4.76% vs. 3.70%, respectively, p = 0.0376). Old age, pulmonary disease, connective tissue disorders, and diabetes were risk factors for chronic kidney diseases but early H. pylori eradication was a protective factor against chronic kidney diseases (hazard ratio: 0.68, 95% confidence interval: 0.52–0.88, p = 0.0030), and death (hazard ratio: 0.69, 95% confidence interval: 0.49–0.96, p = 0.0297). In conclusion, our findings have important implications suggesting that early H. pylori eradication is mandatory since it is associated with a protective role against the occurrence of chronic kidney diseases.

Abstract
BACKGROUND & AIMS The association between Helicobacter pylori infection and end-stage renal disease (ESRD) events remains unknown. We assessed the relationship between H. pylori infection requiring hospital admission and the subsequent risks of ESRD. METHODS This was a retrospective cohort study in which data from the National Health Insurance system of Taiwan was used. The H. pylori-infected cohort comprised 20,068 patients. Each participant was frequency-matched by age and sex with 4 individuals from the general population without H. pylori-infected. Cox proportional hazards regression analysis was used to estimate the influence of H. pylori infection on the risk of ESRD. RESULTS The overall incidence of ESRD was 3.72 times greater in the H. pylori-infected cohort than in the non-infected cohort (11.1 vs. 2.96 per 1000 person-years), with an adjusted HR of 2.58 [95% confidence interval (CI)=2.33-2.86]. The risk of ESRD markedly increased in patients with H. pylori infection combined with at least one of the following concomitant comorbidities: hypertension, diabetes, hyperlipidaemia and coronary artery disease. CONCLUSIONS This is currently the largest nation-based study in which the risk of ESRD in H. pylori-infected patients was examined. H. pylori infection was associated with a subsequent risk of ESRD. H. pylori-infected patients with concomitant chronic kidney disease (CKD) or cardiovascular disease (CVD) risk factors were at higher risk of ESRD than were those who had a single CKD or CVD risk factor.

Abstract
Background. The aim of this study was to investigate the association between iron deficiency anemia and H. pylori in patients with normal gastrointestinal tract endoscopy results. Materials and Methods. A total of 117 male patients with normal gastrointestinal tract endoscopy results were included in this retrospective study. The study and control groups included 69 and 48 patients with and without iron deficiency anemia, respectively. The prevalence of H. pylori, the number of RBCs, and the levels of HGB, HTC, MCV, iron, and ferritin were calculated and compared. Results. There was no statistically significant difference found between the groups according to the prevalence of H. pylori (65.2% versus 64.6%, P = 0.896). Additionally, the levels of RBCs, HGB, HTC, MCV, iron, and ferritin in the patients in the study group were lower than those in the control group (P < 0.05). Finally, there was no association between iron deficiency anemia and H. pylori (OR 1.02, Cl 95% 0.47-2.22, and P = 0.943). Conclusion. H. pylori is not associated with iron deficiency anemia in male patients with normal gastrointestinal tract endoscopy results.

Abstract
While Helicobacter pylori infection was initially revealed to be associated only with some gastroduodenal diseases, further studies have shown its possible role in several extragastric diseases. For idiopathic thrombocytopenic purpura, sideropenic anemia, and vitamin B12 deficiency, the diagnosis of H. pylori infection is recommended, and there are many other conditions such as cardiovascular, neurological, dermatological, and respiratory diseases in which H. pylori may possibly play a role. Interestingly, a potential role has also been described for GI neoplastic diseases, including colorectal and pancreatic cancer. Different mechanisms of action have been proposed, ranging from the induction of a low grade inflammatory state to the occurrence of molecular mimicry mechanisms. This review summarizes the results of the most relevant studies published on this topic over the last year.
