Histo-blood group antigens, which are present on gut epithelial surfaces, function as receptors or attachment factors and mediate susceptibility to rotavirus infection. The major determinant for susceptibility is a functional FUT2 enzyme which mediates the presence of α-1,2 fucosylated blood group antigens in mucosa and secretions, yielding the secretor-positive phenotype. Secretors are more susceptible to infection with predominant rotavirus genotypes, as well as to the commonly used live rotavirus vaccines. Difference in susceptibility to the vaccines is one proposed factor for the varying degree of efficacy observed between countries. Besides infection susceptibility, secretor status has been found to modulate rotavirus specific antibody levels in adults, as well as composition of breastmilk in mothers and microbiota of the infant, which are other proposed factors affecting rotavirus vaccine take. Here, the known and possible effects of secretor status in both infant and mother on rotavirus vaccine take are reviewed and discussed.

Abstract Background VP4 [P] genotype binding specificities of rotaviruses and differential expression of histo-blood group antigens (HBGAs) between populations may contribute to reduced efficacy against severe rotavirus disease. P[6]-based rotavirus vaccines could broaden protection in such settings, particularly in Africa, where the Lewis-negative phenotype and P[6] rotavirus strains are common. Methods The association between HBGA status and G3P[6] rotavirus vaccine (RV3-BB) take was investigated in a phase 2A study of RV3-BB vaccine involving 46 individuals in Dunedin, New Zealand, during 2012–2014. FUT2 and FUT3 genotypes were determined from DNA extracted from stool specimens, and frequencies of positive cumulative vaccine take, defined as an RV3-BB serum immune response (either immunoglobulin A or serum neutralizing antibody) and/or stool excretion of the vaccine strain, stratified by HBGA status were determined. Results RV3-BB produced positive cumulative vaccine take in 29 of 32 individuals (91%) who expressed a functional FUT2 enzyme (the secretor group), 13 of 13 (100%) who were FUT2 null (the nonsecretor group), and 1 of 1 with reduced FUT2 activity (i.e., a weak secretor); in 37 of 40 individuals (93%) who expressed a functional FUT3 enzyme (the Lewis-positive group) and 3 of 3 who were FUT3 null (the Lewis-negative group); and in 25 of 28 Lewis-positive secretors (89%), 12 of 12 Lewis-positive nonsecretors (100%), 2 of 2 Lewis-negative secretors, and 1 of 1 Lewis-negative weak secretor. Conclusions RV3-BB produced positive cumulative vaccine take irrespective of HBGA status. RV3-BB has the potential to provide an improved level of protection in settings where P[6] rotavirus disease is endemic, irrespective of the HBGA profile of the population.

The mapping out of the histologic distribution of blood group antigens A and B in human tissues was performed by means of the fluorescent antibody technique. Human hyperimmune sera were conjugated with fluorescein isocyanate and applied to frozen sections of human material obtained at autopsy or after surgical removal. The material examined encompassed A, B, and AB subjects. In the latter the anti-A and the anti-B conjugate elicited the same picture. Group O tissues were used for controls and were uniformly negative. The secretor status of subjects was determined from the saliva or by the Lewis typing of erythrocytes. The results fall into the following main divisions: Endothelia of Vessels.—Widespread localization was demonstrated in the cell walls of endothelium of capillaries, veins, arteries, and of sinusoidal cells of spleen. Stratified Epithelia.—These showed good outlining of cells of the Malpighian (and the granular, when present) layers. In transitional epithelia, cells of the basal and contiguous layers gave specific staining. Mucus-Secreting Apparatus.—Positive staining was obtained in glands, goblet cells, and secreting surface epithelia. In non-secretors there was no identifiable antigen with the important exception of the deeper parts of gastric foveolae, deeper parts of crypts of Lieberkühn of bowel mucosa and Brunner's glands of the duodenum. Various Organs of Secretion and Excretion.—The pancreas (exocrine portion) and the sweat glands were found to produce the antigen irrespectively of secretor status. Breast, prostate, and endometrial glands on the other hand apparently secrete the antigen in conformity with the subject's secretor:non-secretor make-up. Thus the secretor:non-secretor status governs principally the antigens associated with mucous secretions and this in most but not all locations. The possible nature of this control is briefly discussed.

We demonstrated the immunohistochemical distribution of Le-a and Le-b blood group antigens in human major and minor salivary glands at the ultrastructural level by applying a post-embedding immunogold staining method. In secretors' glands, a faint Le-a reactivity was found only in mucous droplets, whereas Le-b antigen was intensely stained in secretory granules of most mucous cells, in those of intercalated duct cells, in the pale granular matrix of some serous cells, and, when osmication was omitted, in cytoplasmatic vesicles and cell surfaces of striated ducts. In the submandibular gland of a non-secretor, Le-a antigen was considerably stained in mucous droplets, whereas Le-b reactivity was restricted to the striated duct cells. These results indicate that the secretor status affects the secretion of Lewis antigens by mucous, serous, and intercalated duct cells but not the presence of Le-b as a surface antigen in striated duct cells.

IntroductionABO blood group antigens within grafts are continuously exposed to anti-A/B antibodies in the serum of recipients after ABO-incompatible (ABOi) kidney transplantation and are instrumental in antibody-mediated rejection. Some individuals secrete soluble blood group antigens into body fluids. In this study, we investigated the effect of donor and recipient secretor status on the outcomes of ABOi kidney transplantation.MethodsData of a total of 32 patients with ABOi living donor kidney transplantation were retrospectively collected between 2014 and 2020 in West China Hospital. The genotype and phenotype of both donors and recipients were examined and evaluated with post-transplantation anti-A/B titer changes, graft function, and rejection.ResultsOf the 32 recipients and 32 donors, 23 (71.9%) recipients and 27 (84.4%) donors had secretor genotypes, whereas 9 (28.1%) recipients and 5 (15.6%) donors did not. Anti-A/B titers after ABOi kidney transplantation were not significantly influenced by the secretor status of either donors or recipients. The post-transplantation serum creatinine (Scr) levels and estimated glomerular filtration rate (eGFR) was better in weak- or non-secretor recipients at day 30 (Scr P = 0.047, eGFR P = 0.008), day 90 (Scr P = 0.010, eGFR P = 0.005), and month 9 (eGFR P = 0.008), and recipients from secretor donors had a lower incidence of graft rejection in the first year after ABOi transplantation (P = 0.004).ConclusionsA weak secretor status phenotype was found in both genotypes, i.e., individuals who secreted soluble antigens as well as those who did not. The recipient ABH-secretor status may have an influence on early posttransplant renal function, and the donor ABH-secretor status might affect the incidence of graft rejection.

Seronegative Spondyloarthropathies

The classical paradigm of autoimmune pathogenesis involving specific genetic makeup and exposure to environmental triggers has been challenged recently by the addition of a third element, the loss of intestinal barrier function. Regardless of HLA B27 phenotype or gastrointestinal symptoms, evidence of ileitis, ileocolitis or colitis exists in patients with spondyloarthropathy. The FUT2 secretory gene is a strong candidate for Crohn's susceptibility by shaping the functional states of mucosal microbiota and may thus have influence on the release of zonulin, the main regulator of gut permeability. Gram negative bacteria precipitate and may be involved in the pathogenesis of spondyloarthropathies. Susceptibility to many infectious agents is associated with ABO blood group or secretor state. Patients who cannot secrete ABO and Lewis blood group antigens into body fluids, an ability controlled by a single gene on chromosome 19, are known to be at increased risk of certain autoimmune diseases associated with human leukocyte antigen (HLA) markers. Lewis (Le) blood group phenotype can be used to infer secretor status. The objective of this study was to determine the distribution of secretor state and Lewis blood group phenotype in patients with seronegative spondyloarthropathies and healthy control subjects. Hundred and ten (110) patients with seronegative spondyloarthropathies (58 females and 52 males) and 103 control (74 males and 29 females) subjects participated in this study. Samples of saliva and blood were subjected to haemagglutination inhibition tests for determination of secretor status and Lewis phenotype. A total of 92(84%) patients and 92 (89%) control subjects were secretors while 18 (16%) patients and 11 (11%) control subjects were non-secretors. There was no statistically significant difference (?2 1,461 p<0,05 and degrees of freedom 1) in distribution of secretor status in comparison to seronegative spondyloarthropathies by comparing two observed populations. Seven patients had modified (reduced) expression of Lewis b antigen on their erythrocytes. Reduction of Lewis b antigen expression was not observed on erythrocytes of healthy subjects. Reduced expression of Lewis b antigen could be a consequence of the inflammatory process within the gut and it also suggests several pathogenic mechanisms which may be relevant to the synthesis of Lewis antigens inside the gut or its absorption on erythrocytes in patients with spondyloarthropathy.

Group A rotaviruses are a major cause of acute gastroenteritis in children. The diversity and unequal geographical prevalence of rotavirus genotypes have been linked to histo-blood group antigens (HBGAs) in different human populations. In order to evaluate the role of HBGAs in rotavirus infections in our population, secretor status (FUT2+), ABO blood group, and Lewis antigens were determined in children attended for rotavirus gastroenteritis in Valencia, Spain. During three consecutive years (2013–2015), stool and saliva samples were collected from 133 children with rotavirus infection. Infecting viral genotypes and HBGAs were determined in patients and compared to a control group and data from blood donors. Rotavirus G9P[8] was the most prevalent strain (49.6%), followed by G1P[8] (20.3%) and G12P[8] (14.3%). Rotavirus infected predominantly secretor (99%) and Lewis b positive (91.7%) children. Children with blood group A and AB were significantly more prone to rotavirus gastroenteritis than those with blood group O. Our results confirm that a HBGA genetic background is linked to rotavirus P[8] susceptibility. Rotavirus P[8] symptomatic infection is manifestly more frequent in secretor-positive (FUT2+) than in non-secretor individuals, although no differences between rotavirus G genotypes were found.
