[PMID: 39202269 PMCID: PMC11353373 DOI: 10.3390/diagnostics14161781] [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: 07/12/2024] [Revised: 08/05/2024] [Accepted: 08/14/2024] [Indexed: 09/03/2024] Open
Abstract
This article investigates the link between Helicobacter pylori (H. pylori) infection and cardiovascular and neurological disorders. Recent research suggests that H. pylori may play a role in cardiovascular diseases like atherosclerosis, myocardial infarction, and stroke, as well as neurological diseases including Alzheimer's disease, multiple sclerosis, and Parkinson's disease. Cardiovascular Diseases: H. pylori induces endothelial dysfunction and chronic inflammation, promoting atherosclerotic plaque formation and other cardiac complications. High infection prevalence in cardiovascular patients implies that systemic inflammation from H. pylori accelerates disease progression. Eradication therapies combined with anti-inflammatory and lipid-lowering treatments may reduce cardiovascular risk. Neurological Diseases: H. pylori may contribute to Alzheimer's, multiple sclerosis, and Parkinson's through systemic inflammation, neuroinflammation, and autoimmune responses. Increased infection prevalence in these patients suggests bacterial involvement in disease pathogenesis. The eradication of H. pylori could reduce neuroinflammation and improve outcomes. Discussions and Future Research: Managing H. pylori infection in clinical practice could impact public health and treatment approaches. Further research is needed to clarify these relationships. Longitudinal and mechanistic studies are essential to fully understand H. pylori's role in these conditions. Conclusions: H. pylori infection is a potential risk factor for various cardiovascular and neurological conditions. Additional research is critical for developing effective prevention and treatment strategies. Targeted therapies, including H. pylori eradication combined with anti-inflammatory treatments, could improve clinical outcomes. These findings highlight the need for an integrated clinical approach to include H. pylori evaluation and treatment.

Dore MP, Erre GL, Piroddu J, Pes GM. Helicobacter pylori infection and rheumatoid arthritis as risk enhancers' factors for atherosclerotic cardiovascular diseases. Helicobacter 2023; 28:e13025. [PMID: 37792567 DOI: 10.1111/hel.13025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Revised: 09/20/2023] [Accepted: 09/24/2023] [Indexed: 10/06/2023]
Abstract
BACKGROUND In addition to established risk factors for atherosclerotic cardiovascular diseases (aCVDs), infections and autoimmune diseases, such as Helicobacter pylori (H. pylori) and rheumatoid arthritis (RA), have been reported as risk-enhancer factors. In this retrospective single-center, case-control study, the relative weight of RA and H. pylori infection on aCVD was evaluated in a cohort of patients from Northern Sardinia, Italy, where both conditions are frequent. MATERIALS AND METHODS Data were retrieved from records of subjects undergoing upper endoscopy and screened for H. pylori infection by at least four biopsies. The presence of H. pylori and chronic-active gastritis were labeled as a current infection or a long-lasting infection (LLHp) when atrophy and/or metaplasia and/or dysplasia were detected in at least one gastric specimen. Diagnosis of aCVD and RA was made by the cardiologist and the rheumatologist, respectively, according to guidelines. Odd ratios (ORs) for aCVD were evaluated, adjusting for age, sex, excess weight, cigarette smoking, blood hypertension, dyslipidemia, diabetes, H. pylori status, and RA. RESULTS Among 4821 records (mean age 52.1 ± 16.7 years; 66.0% female), H. pylori infection was detected in 2262 patients, and more specifically, a LLHp infection was present in 1043 (21.6%). Three-hundred-three (6.3%) patients were diagnosed with aCVD, and 208 (4.3%) with RA. In patients with aCVD (cases), the LLHp infection (33.3% vs. 20.8%, p < 0.0001) and RA (12.2% vs. 3.8%, p < 0.0001) were more frequent in cases compared with controls (patients without aCVD). After adjusting for traditional aCVD risk factors, ORs significantly increased for LLHp infection (1.57; 95% CI 1.20-2.06) and RA (2.63; 95% CI 1.72-4.02). Interestingly, the LLHp infection in patients with RA showed an overall addictive effect on the risk for aCVD (7.89; 95% CI 4.29-14.53). CONCLUSIONS According to our findings, patients with RA should benefit from being screened and eventually treated for H. pylori infection.

Abstract
It is well documented that Helicobacter pylori (H. pylori) can cause both gastrointestinal and extraintestinal manifestations. The latter one represents a major burden in terms of diagnosis and treatment. H. pylori-associated systemic subclinical inflammation is mostly responsible for the development of extraintestinal manifestations, and its early eradication might result in preventing all adverse events related to their occurrence. Thus, it was suggested that H. pylori might be associated with iron deficiency anemia, thrombocytopenia (immune thrombocytopenic purpura), Schonlein Henoch purpura, failure to thrive, vitamin B12 deficiency, diabetes mellitus, body mass index, cardiovascular diseases, as well as certain neurological conditions. Nevertheless, studies showed both pros and cons in terms of the role of H. pylori in the development of previously mentioned clinical entity underlining the crucial need for further studies on these topics. Although most of these extraintestinal manifestations occur during adulthood, we must not forget that H. pylori infection is acquired mainly during childhood, and thus its early diagnosis and eradication might represent the cornerstone in the prevention of H. pylori-induced inflammatory status and consequently of all related extraintestinal conditions.

Abstract
Background Coronary heart disease (CHD) is one of the leading causes of mortality in the world. Although the traditional risk factors for CHD have been identified, it seems that there are still many CHD cases without these factors. Previous studies have hypothesized that Helicobacter pylori (H. pylori) infection was associated with the risk of CHD. Objective The association between H. pylori infection and the risk of CHD was studied using a systematic evaluation and meta-analysis method. Methods In order to find relevant studies, four electronic databases were systematically searched until August 2021. According to the inclusion and exclusion criteria, studies were screened and data were extracted. Under the random-effects or the fixed-effects model, the odds ratio (OR) and 95% confidence interval (95% CI) were combined. All analyses were conducted using Review Manager software (RevMan 5.4). Results Among the included studies, 2 studies were analyzed for H. pylori stool antigen test, 2 studies were analyzed for H. pylori histological staining test, 13 studies were analyzed for the anti-CagA test, and 38 studies were analyzed for the anti-H. pylori IgG test. The pooled results revealed that positive anti-H. pylori IgG was significantly associated with an increased risk of CHD (OR, 1.58; 95% CI: 1.34–1.87). Similarly, positive anti-CagA, positive H. pylori stool antigen, and positive H. pylori histological staining were significantly associated with the development of CHD with (OR: 1.33, 95% CI: 1.16–1.53), (OR: 3.50, 95% CI: 1.60–7.66), and (OR: 1.78, 95% CI: 1.12–2.83), respectively. Conclusion This meta-analysis showed that H. pylori infection increased the risk of CHD. However, more studies are needed to further investigate whether early eradication of H. pylori may reduce the morbidity of CHD.

Nutr Metab Cardiovasc Dis 2021; 31:169-177. [PMID: 33127250 DOI: 10.1016/j.numecd.2020.07.045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/16/2019] [Revised: 07/10/2020] [Accepted: 07/30/2020] [Indexed: 02/05/2023]
Abstract
BACKGROUND AND AIM Serum pepsinogens (PGs) are biomarkers for gastric mucosal damage and have been reported to be associated with atherosclerosis. Its correlation with atherosclerotic cardiovascular disease (ASCVD) is still unknown. This study aimed to explore the association between serum PGs and ASCVD for providing physicians with an integrative picture to make rational plans in the diagnosis and treatment of ASCVD. METHODS AND RESULTS The concentrations of serum PGs and their distributions between ASCVD and non-ASCVD were compared by non-parametric test, Chi-squared test and Fisher exact test. The correlation between variables was analyzed by Spearman's correlation test. The association of serum PGs with ASCVD was analyzed by the binary logistic regression and two-piecewise linear regression. A total of 8355 recruited cases were eligible for the study. The concentrations of serum PGs were significantly different between the ASCVD and non-ASCVD groups (P = 0.025, P < 0.001). The lower PGI and PGR levels were significantly correlated with a high risk of ASCVD presence after adjustment for 26 potential covariates. Moreover, there was a linear relationship between the high level of PGII and the high risk of ASCVD [adjusted OR = 1.16 (1.00, 1.37), P = 0.07]. A nonlinear relationship of PGI/PGR and ASCVD (P = 0.08/<0.001) was also revealed. The risk of ASCVD increased with a range of log PGI ≥2.13 (PGI≥131 ng/mL) [adjusted OR = 4.67 (1.00, 23.17)], and decreased with a range of log PGR ≥0.22 (1.65) [adjusted OR = 0.59 (0.48, 0.74), P < 0.001]. CONCLUSIONS Serum PGI and PGR are nonlinearly correlated with ASCVD, while PGII is linearly correlated with ASCVD. Among all PGs, PGR may serve as a reliable biomarker for ASCVD.

Abstract
BACKGROUND Helicobacter pylori (H pylori) infection may be a risk factor for cardiovascular disease (CVD), but the reported researches have given conflicting results. AIMS To investigate the association between H pylori infection and risk of atherosclerotic CVD. MATERIALS AND METHODS The studies were retrieved in Embase, PubMed, Web of Science (published from Jan 1, 1990, to Jan 31, 2020, language restrictions: English). All studies included used data from case-control studies and cohort studies of cardiovascular adverse events. Random effect models were used to measure pooled estimates. All data were analyzed with Stata 11.2 SE (StataCorp, College Station, TX). RESULTS Helicobacter pylori infection increased the risk of adverse cardiovascular events by 51% (40 studies, n = 19 691, odd ratio [OR] = 1.51, 95% confidence interval [CI]: 1.34-1.70). The effect was greater for studies that the type of CVDs was myocardial infarction (MI) and cerebrovascular disease (MI OR = 1.80, 95% CI: 1.42-2.26, cerebrovascular disease OR = 1.54, 95% CI: 1.27-1.89). Meanwhile, CagA seropositive H pylori strains were associated with a significantly increased risk of cardiovascular adverse events based on published research data (OR = 1.73, 95% CI: 1.40-2.14). CONCLUSION In conclusion, H pylori infection enhanced the risk of atherosclerotic cardiovascular adverse events, especially in some patients with MI and cerebrovascular disease. This study will provide guidance for the targeted prevention and treatment of CVDs. But this association need to be confirmed by more prospective studies.

Abstract
BACKGROUND Stroke stands among the most leading causes of mortality worldwide. Although modifiable risk factors for stroke have been identified, current risk factors do not sufficiently explain the risk in young patients. Previous studies have postulated an association between infection by Helicobacter pylori (HP) and stroke. OBJECTIVE To investigate the association between HP infection and stroke by using a systematic review and meta-analysis approach. METHODS Four electronic search engines/libraries were systematically searched for relevant observational studies. Studies were screened for eligibility and data were extracted. The odds ratio (OR) and 95% confidence interval (95% CI) were combined under the random-effect model. The protocol was registered in PROSPERO (CRD42019123689). RESULTS Among the included studies, 25 studies were analyzed for anti-HP IgG, 9 studies were for anti-Cag A, and 6 studies were for the C-urea breath test. The results showed that positive anti-HP IgG was significantly associated with an increased risk of stroke [OR (95% CI) = 1.43 (1.25-1.46)]. Similarly, both antiCag A and C-urea breath test were significantly associated with an increased risk of stroke with [OR (95% CI) = 1.77 (1.25-2.49)], and [OR (95% CI) = 2.21 (1.33-3.66)], respectively. Furthermore, our results indicated that positive anti-HP IgG was associated with stroke caused by atherothrombosis and small artery disease. CONCLUSIONS This study suggests that HP infection is significantly associated with increased risk of stroke. However, more well-designed studies are required to investigate if early HP eradication might decrease the incidence of stroke.

Abstract
Many studies have been performed concerning the potential role of Helicobacter pylori (H. pylori) in different extra-gastric diseases. Ischemic heart disease (IHD) remains the leading cause of mortality in developed countries. The traditional cardiovascular risk factors could not predict all cases of IHD. Hence, the scientists explore other potential etiologic factors, especially infections. H. pylori infection has been suspected to have a role in the pathogenesis of atherosclerosis. However, after 25 years from the first description, the role of the bacterium in the pathogenesis of IHD remains controversial and enigmatic. Since H. pylori infection is persistent and stimulates both a local and a systemic immune response that could cause significant changes in the markers of inflammation like cytokines, C-reactive protein, heat shock protein, fibrinogen, triglycerides, high density lipoprotein, it has been supposed that the outcomes of this process are atherosclerosis and a prothrombotic state which eventually leads to IHD. Alternative pathogenic mechanisms have been hypothesized, including the occurrence of molecular antigenicity. This hypothesis supposed that H. pylori could provoke autoimmunity as a result of molecular mimicry. The eradication of H. pylori infection as cardiovascular prevention strategy has been the object of some studies. However, the results are of difficult interpretation. Further studies, especially with a cohort and interventional design, have to be performed to reveal the potential relationship between H. pylori and IHD.

Abstract
A potential contribution of H. pylori contamination to low-grade inflammation, oxidative stress (OS) and insulin resistance as well as correlations between these parameters in asymptomatic sedentary males was analysed. We enrolled 30 apparently healthy asymptomatic young subjects (18 H. pylori negative and 12 positive) and measured whole blood glucose, glycated haemoglobin, insulin, C-peptide, cortisol, aldosterone, testosterone, thyroid stimulating hormone, C-reactive protein, interleukins 6 and 10, TNF-alpha and comet assay. As markers of OS, we used urine levels of iso-PGF2-α and 1,4-dihydroxynonane mercapturic acid (DHN-MA). Twofold elevation of fasting insulin level and HOMA index in H. pylori-positive subjects (p < .05) was shown. Inflammatory parameters and monocyte DNA damage, urine levels of DHN-MA and iso-PGF2-α did not show significant differences between the groups. The early stage of H. pylori-triggered metabolic derangements in sedentary subjects include development of insulin resistance in H. pylori-positive subjects; however, there is no evidence of systemic inflammatory and OS-related changes.

Abstract
Helicobacter pylori-induced oxidative stress in gastric mucosa (GM) is a milieu for the development of chronic gastritis, duodenal peptic ulcer (DPU), gastric cancer, and a number of extragastric diseases. Because our previous study revealed the accumulation of the protein adducts of lipid peroxidation product 4-hydroxynonenal (HNE) in GM, which persists after eradication of H. pylori, the aim of the study was to test whether Amaranth oil supplementation in addition to standard anti-Helicobacter treatment could prevent such accumulation of HNE in GM in H. pylori-positive DPU patients. Seventy-five patients were randomly split into two groups: group 1 - standard treatment (n = 39) and group 2 - standard treatment with additional supplementation of 1 ml of concentrated oil from amaranth seeds (Amaranthus cruenthus L., n = 36). Clinical analysis, including endoscopy with biopsies from antrum and corpus of the stomach were performed before and after the treatment, as was heart rate variability (HRV) recorded, as parameter of systemic, extragastric pathophysiological alterations in DPU patients. Improvement of clinical, endoscopic and histologic manifestations, and successful ulcer healing were observed in both the groups. Moreover, supplementation of amaranth oil in addition to standard anti-H. pylori treatment significantly reduced accumulation of HNE-histidine adducts in GM and increased HRV in DPU patients (p < .05). Therefore, standard treatments of DPU require additional therapeutic approaches, in accordance with integrative medicine principles, aiming to reduce persistence of oxidative stress, as was successfully done in our study by the use of amaranth oil.

Abstract
During the past year, many articles were published on the extragastric diseases related to Helicobacter pylori infection. This supports the theory that some microorganisms may cause diseases even far from the primary site of infection by interfering with different biologic processes. The role of H. pylori on idiopathic thrombocytopenic purpura, sideropenica anemia, and vitamin B12 deficiency is well known. On the other hand, there is a growing interest in the bacterium's association with cardiovascular, neurologic, hematologic, dermatologic, head and neck, and uro-gynecologic diseases, as well as diabetes mellitus and metabolic syndrome, with very promising results. This review has been aimed at summarizing the results of the most relevant studies published over the last year on this fascinating topic.

Abstract
The discovery of Helicobacter pylori (H. pylori) colonization of the stomach and its pathogenic effects is a crucial landmark in modern gastroenterology. There have been many studies reporting that the natural history of many disorders of the upper gastrointestinal tract, such as chronic gastritis, peptic ulcer disease, gastric cancer and MALT lymphoma are linked with the presence of this bacterium. Moreover, H. pylori is often involved in the pathogenic processes of a variety of extra-gastric diseases, especially those characterized by persistent and low grade systemic inflammation. The proposed mechanisms ranging from the induction of a low grade inflammatory state to the occurrence of molecular mimicry mechanisms. This paper will review the results of the most important studies on the association of H. pylori infection with extra-gastric diseases, such as autoimmune, neoplastic, cardiovascular and other related disorders, as well as possible mechanisms implicated in the pathogenesis of these extra-gastric diseases.

Abstract
AIM: To investigate the relationship between Helicobacter pylori (H. pylori) infection and coronary atherosclerotic heart disease (CAHD).
METHODS: A total of 1030 patients with CAHD and 1116 patients with non-coronary atherosclerotic heart disease underwent 14C-urea breath test. H. pylori positive rate were compared between the two groups. The CAHD group was further divided into two groups according to the test results for H. pylori: an H. pylori positive group and an H. pylori negative group. According to SYNTAX score, CAHD patients were divided into a low risk group, a moderate risk group, and a high risk group, and the difference in H. pylori positive rates was analyzed.
RESULTS: The positive rate of H. pylori in patients with CAHD was higher than that of the control group. Serum homocysteine level in H. pylori positive CAHD patients was significantly higher than that in the negative group (P < 0.01). The positive rate of H. pylori in the high risk group was the highest, followed by moderate and low risk groups, but the difference was not statistically significant (P > 0.05). Serum homocysteine level increased with the increasing of the CAHD risk degree in H. pylori positive CAHD patients (P < 0.01).
CONCLUSION: H. pylori infection is an important risk factor for CAHD. H. pylori infection may increase the degree of CAHD by elevating serum homocysteine levels, thereby promoting the development of coronary atherosclerosis.
