ABO, Lewis blood group systems and secretory status with H.pylori infection in yemeni dyspeptic patients: a cross- sectional study. BMC Infect Dis 2023; 23:520. [PMID: 37553651 PMCID: PMC10408178 DOI: 10.1186/s12879-023-08496-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2023] [Accepted: 07/31/2023] [Indexed: 08/10/2023] Open
Abstract
BACKGROUND The ABO and Lewis blood group antigens are potential factors in susceptibility to H. pylori infection. This research aimed to examine the prevalence of Helicobater pylori (H.pylori) infection and its association with ABO, Lewis blood group systems, and secretory status in Yemeni symptomatic patients. METHODS In a cross-sectional study, 103 patients referred for endoscopy due to dyspepsia were included. H pylori infection was assessed using stool antigen and serum antibody rapid tests. ABO and Lewis blood group systems were examined using hemagglutination assay. Saliva samples were investigated for identification of the secretory phenotype using hemagglutination inhibition test. RESULTS The prevalence of H. pylori infection was (80.6%), with a higher rate of infection in females than males. The ABO blood groups were found to be significantly different between males and females (p = 0.047). The O blood group was prevalent among H. pylori patients, especially secretors. There was a significant association between ABO blood groups and H. pylori infection (p = 0.001). The Le (a + b+) phenotype was the most common, followed by Le (a + b-), Le (a-b+), and Le (a-b-). Lewis blood group systems and secretory status of symptomatic patients were not associated with H. pylori infection. The results showed that serum Ab test for H. pylori achieved poor sensitivity (68%), specificity of 55%; positive predictive value (PPV) 86%, negative predictive value (NPV) 29% and accuracy 65.1%. CONCLUSION The prevalence of H. pylori infection was high in Yemeni patients. This infection was linked to the O and Le (a + b+) secretor phenotype. The H. pylori stool Ag test is the most reliable noninvasive diagnostic method for detecting H. pylori infection.

Abstract
Early evidence from China suggested that blood groups may be involved in susceptibility to COVID‐19. Several subsequent studies reported controversial results. We conducted a retrospective matched case‐control study that aims to investigate the association between blood groups and the risk and/or severity of COVID‐19. We compared the blood groups distribution of 474 patients admitted to the hospital for COVID‐19 between March 2020 and March 2021, to that of a positive control group of outpatients infected with COVID‐19 and matched them for sex and age, as well as to the distribution in the general population. Three hundred and eighteen HC+ pairs with available blood group information were matched. The proportion of group A Rh+ in hospitalized patients (HC+) was 39.9% (CI 35.2%–44.7%), compared to 44.8% (CI 39.8%–49.9%) and 32.3% in the positive outpatient controls (C+) and the general population (C−), respectively. Both COVID‐19‐positive groups (HC+ and C+) had significantly higher proportions of group A Rh+ compared to the general population (p = 0.0019 and p < 0.001, respectively), indicating that group A Rh+ increases susceptibility to COVID‐19. Although blood group A Rh+ was more frequent in the outpatients C+ compared to the hospitalized group HC+, the association did not reach statistical significance, indicating that blood group A Rh+ is not associated with severity. There was no significant relationship between COVID‐19 and other blood groups. Our findings indicate that blood group A Rh+ increases the susceptibility for COVID‐19 but is not associated with higher disease severity.

Abstract
The glycosyltransferases encoded by genes from the human ABO, Lewis, and Secretor histo-blood group systems synthesize part of the carbohydrate antigens in hematopoietic and non-hematopoietic tissues. The combined action of these glycosyltransferases strongly influences cell, tissue, mucosa, and exocrine secretion carbohydrate phenotypes, including those serving as habitat for mutualistic and pathogenic microorganisms. A set of reports investigated associations between Toxoplasma gondii infection and the ABO histo-blood group system, but the results are contradictory. As T. gondii uses the gastrointestinal tract as a route for infection, and in this organ, the expression of ABO, Lewis, and Secretor histo-blood group carbohydrates occurs, it is reasonable to suppose some biological relationship between them. This text reviewed association studies published in recent decades focusing on the potential contribution of the ABO, Lewis, and Secretor histo-blood group carbohydrates and infection by T. gondii.

Abstract
OBJECTIVE There is insufficient study of the association of blood groups with neonatal diseases. The aim of this study was to evaluate the blood groups associated with sepsis and blood groups in preterm infants. STUDY DESIGN This retrospective study was conducted between January 1, 2010 and November 31, 2018 in the neonatal intensive care unit (NICU). This study was done in single-center tertiary NICU. Infants born at gestational age (GA) <32 weeks with birth weight (BW) <1,500 g were included in the study. RESULTS A total of 2,548 infants were included. The culture-proven sepsis ratio (30.2%) was the lowest in the O blood group and the highest in the AB blood group (37.5%) (p = 0.045). Meningitis ratio (6.5%) was significantly higher, and hospital stay (64.1 ± 33.9 days) was significantly longer in B blood group (respectively, p = 0.005, p < 0.001). In the AB blood group, GA (27.68 ± 1.12 weeks) was the lowest and early onset sepsis (EOS) (40.1%) and mortality (28.9%) ratio were found to be statistically higher (p < 0.001 for all groups). The AB group was significantly related to higher frequency of EOS (odds ratio [OR] = 2.93, 95% confidence interval [CI] = 1.68-5.12, p = 0.000), in addition to mortality (OR = 1.1, 95% CI = 0.55-2.19, p = 0.001). The O group was found to be associated with lower risk of late onset sepsis (LOS) (OR = 1.67, 95% CI = 1.06-3.058, p = 0.003) according to the model with corrected risk factor including GA, BW, and time of hospitalization. CONCLUSION Our study was the first study showing a relationship between certain blood groups and EOS/LOS in premature infants as well as meningitis.

Abstract
Food nutrients plays a crucial role in human health, especially in gastrointestinal (GI) health. The effect of food nutrients on human health mainly depends on the digestion and fermentation process in the GI tract. In vitro GI digestion and fermentation models had the advantages of reproducibility, simplicity, universality, and could integrally simulate the in vivo conditions to mimic oral, gastric, small intestinal and large intestinal digestive processes. They could not only predict the relationship among material composition, structure and digestive characteristics, but also evaluate the bioavailability of material components and the impact of digestive metabolites on GI health. This review systematicly summarized the current state of the in vitro simulation models, and made detailed descriptions for their applications, advantages and disadvantages, and specially their applications in food carbohydrates. In addition, it also provided the suggestions for the improvement of in vitro models and firstly proposed to establish a set of standardized methods of in vitro dynamic digestion and fermentation conditions for food carbohydrates, which were in order to further evaluate more effects of the nutrients on human health in future.

Abstract
BACKGROUND Helicobacter pylori infection occurs in 50% of the world's population and represents a major risk factor for chronic gastritis, gastroduodenal ulcer and gastric cancer in developed and developing countries. The distribution of H. pylori virulence factors is diverse and varies geographically, such as the CagA and VacA genes, which have revealed association with disease status. Some findings show increased frequencies of these diseases in O Le (a-b +) and A Le (a-b +) blood type individuals, but other studies not found any relationship between these blood groups and H. pylori infection. AIM This study aimed to elucidate probable controversies described in the relationship between the ABH/Lewis blood groups and H. pylori, contributing to the severity of gastric diseases in northern the population of Belém -Pará.-Brazil. METHODS This cross-sectional study included 288 samples of patients separate into two groups with gastric cancer and chronic gastritis. Blood, saliva, and gastric biopsy were analyzed using modified Gram and hematoxylin-eosin staining techniques, the enzyme immunoassay Elisa and Multiplex PCR. The antigens expression of ABH and Lewis systems was determined through Dot-ELISA and direct hemagglutination. Proportions were compared in univariate analysis, while the relation between putative risk factors including H. pylori status and ABO/Lewis phenotype was performed using multivariable logistic regression analyses, P-value < 0.05 was considered significant. RESULTS The findings of this study demonstrate that the likelihood of developing gastric cancer increases threefold if the individual is from A1 Le (a-b +) blood group, has premalignant changes, and infection with H. pylori virulent strains (cagA+/vacA + s1m1). CONCLUSION Therefore, this study found a significant association between ABO and Lewis phenotypes and H. pylori cagA status into the relevance of the development of gastric carcinogenesis.

Abstract
Human ovarian cyst glycoproteins (HOC, cyst gps) isolated from pseudomucinous type of human ovarian cyst fluids is one of the richest and pioneer sources for studying biosynthesis, structures and functional roles of blood group ABH, Lea,b,x,y, sLea and sLex active glycoproteins. After 70+ years of exploration, four top highlights are shared. (i) an updated concept of glycotopes and their internal structures in cyst gps was composited; (ii) the unknown codes of new genes in secreted cyst gps were unlocked as Lex and Ley; (iii) recognition profiles of cyst glycans and a sialic acid-rich (18%) glycan with lectins and antibodies were shown. (iv) Co-expression of Blood Group A/ A-Leb/y and B/B-Leb/y active Glycotopes in the same glycan chains were isolated and illustrated. These are the most advanced achievements since 1980.

Abstract
The ABH and Lewis antigens were among the first of the human red blood cell polymorphisms to be identified and, in the case of the former, play a dominant role in transfusion and transplantation. But these two therapies are largely twentieth century innovations, and the ABH and related carbohydrate antigens are not only expressed on a very wide range of human tissues, but were present in primates long before modern humans evolved. Although we have learned a great deal about the biochemistry and genetics of these structures, the biological roles that they play in human health and disease are incompletely understood. This review and its companion, to appear in a later issue of Vox Sanguinis, will focus on a few of the biologic and pathologic processes which appear to be affected by histo-blood group phenotype. The first of the two reviews will explore the interactions of two bacteria with the ABH and Lewis glycoconjugates of their human host cells, and describe the possible connections between the immune response of the human host to infection and the development of the AB-isoagglutinins. The second review will describe the relationship between ABO phenotype and thromboembolic disease, cardio-vascular disease states, and general metabolism.

Abstract
Helicobacter pylori has a number of well-characterized carbohydrate-binding adhesins (BabA, SabA, and LabA) that promote adhesion to the gastric mucosa. In contrast, information on the glycoconjugates present in the human stomach remains unavailable. Here, we used MS and binding of carbohydrate-recognizing ligands to characterize the glycosphingolipids of three human stomachs from individuals with different blood group phenotypes (O(Rh-)P, A(Rh+)P, and A(Rh+)p), focusing on compounds recognized by H. pylori We observed a high degree of structural complexity, and the composition of glycosphingolipids differed among individuals with different blood groups. The type 2 chain was the dominating core chain of the complex glycosphingolipids in the human stomach, in contrast to the complex glycosphingolipids in the human small intestine, which have mainly a type 1 core. H. pylori did not bind to the O(Rh-)P stomach glycosphingolipids, whose major complex glycosphingolipids were neolactotetraosylceramide, the Lex, Lea, and H type 2 pentaosylceramides, and the Ley hexaosylceramide. Several H. pylori-binding compounds were present among the A(Rh+)P and A(Rh+)p stomach glycosphingolipids. Ligands for BabA-mediated binding of H. pylori were the Leb hexaosylceramide, the H type 1 pentaosylceramide, and the A type 1/ALeb heptaosylceramide. Additional H. pylori-binding glycosphingolipids recognized by BabA-deficient strains were lactosylceramide, lactotetraosylceramide, the x2 pentaosylceramide, and neolactohexaosylceramide. Our characterization of human gastric receptors required for H. pylori adhesion provides a basis for the development of specific compounds that inhibit the binding of this bacterium to the human gastric mucosa.
