Serological and molecular analysis of ABO and Rh blood group chimeras

The serological examination, blood transfusion strategies and the molecular analysis to blood group chimera were conducted to demonstrate existent of chimera in blood group. The blood grouping of ABO or/and RhD, newborn red blood cells separated by capillary centrifugation. Aabsorption tests and DTT treated agglutination erythrocyte tests were implemented in four patients. Further molecular biological research was conducted on one patient''s sample. The results showed that for patient 1: ABO blood group was AB/B chimera, Rh blood cells contained the RhCE chimera gene; Patient 2: Rh blood cells contained the RhD chimera gene; Patient 3: ABO blood group was AB/B chimera, Rh blood cells contained the RhD chimera gene; Patient 4: ABO blood group was O/B chimera, Rh blood cells contained the RhCE chimera gene. The study suggests that the individuals categorized as chimeras are likely to be more common than existing literature reports. According to the serological tests, in the absence of a history of recent blood transfusion or disease to cause reduced antigen, the phenomena of hybrid aggregation of the ABO and Rh blood system were the main feature. In terms of transfusion strategy, the selection of ABO and Rh blood groups should be depended on the group of cells with more antigens.     

Interaction between haptoglobin subtypes and AB0 blood groups in a Bengalee population

Blood samples from 621 individuals of a Caste Hindu Population from West Bengal (India) were investigated in an attempt to find out an association between the AB0 blood groups and Haptoglobin (HP) subtypes. AB0 blood grouping was done on the basis of the agglutination test with standard anti-sera. Haptoglobin subtyping only for the HP*1 allele was done by Polyacrylamide Gel Electrophoresis (PAGE). A significant association was found with a significantly lower HP*1S allele frequency in blood group 0 versus other AB0 blood groups. A comparatively higher allele frequency of HP*1S was found in this population sample. An inverse relationship between HP*1S and HP*2 has been revealed in each blood group. It appears that the major portion of HP*1 alleles in the A, B, and AB blood groups belongs to the HP*1S allele compared to that of the 0 blood group.     

A study of diabetes in relation to blood groups and cholesterol levels

Summary Four hundred and sixteen patients suffering from diabetes were studied for AB0 Rhesus blood groups, to find out whether there is any association between blood group and diabetes. Though the relative incidence was found to be higher in blood group 0 and B, the difference was not statistically significant. This study confirms the earlier findings of high cholesterol levels in diabetes, particularly in patients with blood groups A and AB, and the overall mean cholesterol level as 253 mg/100 ml. This study also shows that diabetes with a cholesterol level of more than 300 mg/100 ml is a coronary risk factor.

Zusammenfassung 416 Patienten mit Diabetes wurden nach AB0 und Rh untersucht, um Assoziationen zwischen Blutgruppe und Diabetes zu finden. Es fand sich ein leichtes, nicht signifikantes Überwiegen von 0 und B. Ein besonders hoher Serum-Cholesteral-Spiegel fand sich beim Diabetes insbesondere bei Patienten der Gruppen A und AB. Die Studie zeigt auch, daß ein Cholesteral-Spiegel von mehr als 300 mg% ein Risikofaktor für Coronarerkrankungen ist.

     

Seasonal effects on fetal selection related to AB0 blood groups of mother and child.

An association of AB0 blood groups and month of birth was examined in two groups, students and newborns in Tokyo. Among 4919 students born mainly in the 1960s, an apparent seasonal variation was shown in births of blood group B students. Among 3592 newborns at an obstetric clinic in the 1980s seasonal variation was also observed in all four blood groups. The ratio of 0 group to A group newborns (0/A ratio) from 0 mothers was lower than that from A mothers among the 0 and A pairs contrary to the expected effects of 0-A incompatibility. The 0/A ratio was apparently different by season and the 0/A ratio from 0 mothers was significantly lower than that from A mothers among those born during August-January. It is assumed that an association of birth season with AB0 blood group may be caused by some seasonally and secularly changing environmental "infertility factors" such as infectious microorganism which may have some common components with a particular blood group substance respectively and induce a loss of embryos selectively at a particular season.     

Problems in the genetics of peptic ulcer. II. An analysis of the associations of the disease with certain simply heritable traits]

The research of distribution of blood group ABO, Rhesus, Lewis, Secretor, C5+-component of choline esterase and the ability to taste PTC among Moscow population patients suffering from duodenal ulcer is carried out in comparison with the control. Statistically authentic association of the disease with 0(I) blood group, unsecretor and the association of joint signs (coefficients of association are 1.32, 2.17 and 2.62 respectively) is found. Authenticity of relation with disease is not proved during the investigation of other signs. The values of risk to fall ill for the patients possessing and not possessing the signs of duodenal ulcer are obtained (concerning separate factors and joint factors). It is established that the combination of 0(I) blood group and unsecretor increases the risk of the diseases in 2.4 times as compared with the patients possessing A, B, AB blood groups and secretors.     

Distribution of AB0 and RH blood group alleles in different populations of southern Punjab, Pakistan.

The analysis of a sample of 1632 individuals from patients of the Nishtar Teaching Hospital, Multan, suggests that different ethnic groups (Araeen, Mughals, Syed, Jat, Rajputs, Baloch and Pathan) are not significantly different from another with regard to the distribution of RH blood group alleles (RH*d around 0.30). The distributions of the AB0 blood group alleles suggest that different ethnic groups are not significantly different from the average alele frequencies (AB0*A = 0.23, AB0*B = 0.33, AB0*0 = 0.47) except for the Pathan ethnic group (AB0*A = 0.35, AB0*B = 0.47, AB0*0 = 0.27). The populations of different geographic areas are not significantly different from the average allele frequencies, except for the southern district of Rahim Yar Khan (AB0*A = 0.12) and the northern district of Sahiwal (AB0*A = 0.19). The populations of Sahiwal (RH*d = 0.35) and Muzaffargarh (RH*d = 0.36) yield significantly different allele frequencies at the RH locus. The interpopulation differences can be explained by the geographic distance. There is a significant difference in the frequencies of the AB0 alleles between rural and urban populations, suggesting that rural populations maintain their isolation from urban populations. Rural and urban populations are not significantly different from one another concerning the allele frequencies at the RH locus.     

Interaction between AB0 and haptoglobin in a white Australian population

Blood samples from over 2,200 blood donors resident in the State of Victoria were investigated for the association between the AB0 and haptoglobin (HP) blood systems reported by others. No association between the phenotypes of the 2 systems was found but the distribution of the HP*1 allele varied among AB0 groups, and the difference between those who were group 0 and the other AB0 groups combined was significantly (p less than 0.05). Overall, the findings were similar, but not as pronounced, as those reported in the Hutterites.     

AB0 blood groups,inv serum groups,and serum proteins in leprosy patients from West Bengal (India)

Summary The associations between ABO blood groups and prevalence as well as type and severity of the leprosy infection were examined in 1034 Indians from West Bengal (leprosy patients and normal controls). There are no associations in the present series; combined analysis of 41 series from the literature (ours included) gives a slightly, but significantly higher frequency of groups A and AB as compared to B and 0 in leprosy patients. Groups A, B, and AB are also somewhat more frequent in lepromatous as compared with nonlepromatous leprosy.A lower level of ₂-globulins in the serum of leprosy patients of groups A and AB as compared with patients of groups B and 0, which had been described earlier in 683 leprosy patients from Thailand, was confirmed in the present series.In the Thai series of patients, a significant association between the AB0 blood groups and the Inv serum groups was observed: Persons having blood group A and AB as well as the Inv (1) type were significantly more frequent than expected. This association, however, was not confirmed in the Indian material.

Zusammenfassung Die Beziehungen zwischen AB0-Blutgruppen sowie Häufigkeit, Typ und Verlauf der Lepraerkrankung wurden an 1034 Indern aus West-Bengalen (Lepra-Patienten und normalen Kontrollen) untersucht. In dieser Serie fanden sich keine Beziehungen. Eine kombinierte Analyse von 41 Serien aus der Literatur (unsere eingeschlossen) gibt eine gering, aber signifikant erhöhte Häufigkeit der Gruppen A und AB im Vergleich zu B und 0 bei Lepra-Patienten. Die Gruppen A, B und AB sind im Gesamtmaterial ebenfalls etwas häufiger bei lepromatöser im Vergleich zu nichtlepromatöser Lepra.Bei 683 Lepra-Patienten aus Thailand hatten wir zuvor eine Verminderung der ₂-globuline bei Gruppen A und AB im Vergleich zu B und 0 beschrieben. Dieser Befund wurde an dem indischen Material bestätigt.Bei den thailändischen Patienten fanden sich auch Hinweise für eine Beziehung zwischen AB0- und Serum Inv-Gruppen: Personen, die sowohl A oder AB als auch den Typ Inv (1) aufwiesen, waren signifikant häufiger als erwartet. Dieser Befund konnte jedoch in dem indischen Material nicht bestätigt werden.

ABO and Rh blood groups in diabetes mellitus

The present investigation was conducted with a view to testing the hypothesis that there is some association between blood groups (ABO and Rh) and diabetes mellitus. 520 proven cases of adult diabetes mellitus from the Diabetic Clinic of Rajendra Hospital, Patiala, were studied in 1979-1980. A large sample of 6204 normal individuals studied by Jolly et al. (1969) for ABO and Rh blood groups was taken as control for comparison with the patients. There is a strong indication of an association of diabetes mellitus with blood groups, especially with A, AB and Rh-positive blood groups. The maximum differences are in the AB groups in the two series and minimum in the A group. Individuals with gene p seem to be more susceptible to this disease. Thus the association between blood groups and diabetes mellitus is not a chance finding, but implies an aetiological relationship.     

AB0-Blutgruppen bei rheumatischem Fieber und rheumatischer Karditis

The authors desribe a highly significant association between the AB0 blood group system and rheumatic carditis in Budapest samples (770 patients, 3830 controls). Persons belonging to blood group AB or A are more susceptible to this disease than others, while groups B and 0 are relatively protected. The influence of AB0-locus on the disease can be estimated as being of the order of 1/2% by the relative risk x=1.376 and a 2% incidence. The evaluation of studies published so far proved only the relative protection of group 0 against rheumatic fever; it seems probable that of persons suffering from rheumatic fever especially those of group A are more susceptible to develop carditis. The hypothesis is discussed that the relative protection of the blood group 0 and of the secretor phenotype against rheumatic fever could be based on the partial identity of the determinant groups of the human H-antigen —which is found in abundance in the body fluids of all secretors-and of the C-substance of the group A Streptococcus, which inhibits the allergic reaction.

Evidence for an association between AB0 blood group and goitre

Summary A medical and genetic study on KarKar Island, Papua New Guinea revealed a significant association between AB0 blood group status and susceptibility to goitre with 0 individuals more susceptible than non-0. The association is found in a number of separate villages on the island which indicates that it is not due simply to chance concordance in geographical patterns of genetic and disease variation.     

AB0 blood groups and the type of leprosy in an Indian population

In 931 leprosy patients from Bankura, West Bengal, India, the relationship between the AB0 blood group and the immunological type of leprosy (lepromatous vs. nonlepromatous) was examined. Among the 472 lepromatous patients, there was a slight excess of blood group A (and also AB and B) as compared with the nonlepromatous group. This excess was not significant statistically in our material. However, combination of the data with those published by Beiguelman (1964) from Brazil and Yankah (1965) from Ghana renders a significantly higher incidence of group A (and probably B and AB) in lepromatous patients.The examinations were supported by WHO (Grant No. G 3/181/15), by the Deutsche Forschungsgemeinschaft and by the Indian Statistical Institute.

Venous thromboembolism and AB0 blood groups in a Brazilian population

Summary The AB0 blood groups were determined in 125 patients suffering from venous thrombosis in a Brazilian population. There is a clear effect of the sex on the disease incidence, women being more frequently affected, but the mean age was not different regarding the sex. No differences were found in the disease incidence when Caucasians and Negroids were compared. An excess of blood group A and a decrease of blood group 0 was observed among the patients. The analysis of the combined data from ten different published series shows a A/0 relative incidence significantly higher than unity, but the heterogeneity was also significant in the series.     

HLA antigens, blood groups and serum protein groups in patients with intermittent claudication

HLA (A and B) antigens, blood group systems (AB0, Rh, MNSs P, Kell, Lewis and Duffy) and serum group systems (Hp, Tf, Pi, C3 and C4) were studied in patients with intermittent claudication (IC) and controls. HLA antigen A 28 was significantly more common, and blood group 0 was significantly less common among the patients than among the controls. A comparison between patients with IC and those with abdominal aortic aneurysms showed a significant difference between these two groups concerning the MN blood groups.     

Metabolic changes in blood in pulmonary tuberculosis patients from various blood groups

285 Patients suffering from the respiratory tract organs primary tuberculosis were subjected to the tests on definition of blood groups according to AB0 system, as well as its total proteolytic activity, alpha 1-antitrypsin, ceruloplasmin, general haptoglobin, lysozyme, malonic dialdehyde and diene conjugates levels were estimated. The sick persons as compared with the healthy ones were defined to reveal a tendency to increase of the persons with 0(I)- and B(III)-blood groups and decrease of those ones with A(II)-groups. Independently on the pulmonary tuberculosis patients phenotypic index their tested blood biochemical indices levels increase. As an exception is the proteolytic activity of the persons with B(III)- blood group, and also alpha 1-antitrypsin and lysozyme--with 0(I) and AB(IV) groups, in this case their rates failed to exceed the norm confidential interval. The blood metabolic parameters were defined as independent on its group.     

Aberrant glycosylation based on the neo-expression of poly- N-acetyllactosamine structures in squamous cell carcinomas of the head and neck

An immuno- and lectin-histochemical study was performed to investigate the aberrant expression of blood group-related antigens and poly-N- acetyllactosamine structures in squamous cell carcinomas of the maxillary sinus, the larynx, the apipharynx, the hypopharynx, the oral cavity, the parotid gland and the tonsil from 52 patients using monoclonal antibodies against A, B and H antigens, and six lectins, UEA-I, PNA, VVA-B4, PWM, LEA and DSA. In addition, GSA- II staining following endo-·-galactosidase digestion procedure was also applied. A, B and H antigens were expressed in most normal epithelial cells of head and neck organs, and depended on the patient blood type. However, in squamous cell carcinoma, A antigen was not detected in eight out of 25 individuals of blood groups A and AB, although B antigen was consistently expressed in carcinoma cells from all the B and AB individuals. On the other hand, H antigen was expressed in carcinoma cells not only from all blood group O individuals, but from 32 out of 35 individuals of blood groups A, B and AB. T and Tn antigens, which are recognized by PNA and VVA-B4, were strongly expressed in carcinoma cells from 40 and 42 out of 52 individuals respectively. Reactivity with GSA-II staining following endo-·-galactosidase digestion, which recognizes linear poly-N-acetyllactosamine structures, was found in a few malignant cells from 21 individuals. Staining with anti-A, -B and -H monoclonal antibodies and UEA-I lectin was diminished after endo-·-galactosidase digestion in some cases. Lectins specific for poly-N-acetyllactosamine, such as PWM, LEA and DSA, exhibited reactivity in some malignant cells from 30, 22 and 32 out of 52 individuals respectively. These results suggested that the expression of the blood group-related antigens is suppressed and immature carbohydrate chains, that is H, T and Tn antigens, are accumulated in squamous cell carcinomas of the head and neck. The results further suggested that poly-N-acetyllactosamine structures are simultaneously synthesized along with the deletion of A antigen and the accumulation of precursors This revised version was published online in November 2006 with corrections to the Cover Date.     

Preeclampsia and ABO blood groups: a systematic review and meta-analysis

Preeclampsia (PE) is a multifactorial pregnancy-specific syndrome which represents one of the leading causes of maternal mortality worldwide. Inherited thrombophilia have been investigated as risk factor for the development of PE and it is currently known that ABO blood group may impact haemostatic balance, having the non-O blood groups (A, B or AB) subjects increased risk for thrombus formation, as compared to those of group O. We performed a systematic review of the literature for published studies investigating whether ABO blood groups could influence PE developing. A sensitive search of four databases identified 45 unique titles. The retrieved papers were assessed independently by authors and a rigorous process of selection and data extract was conduct. Methodological quality of the included studies was also evaluated. Two studies met eligibility criteria. As a main finding of our systematic review, an association between the AB blood group and the occurrence of PE was detected based on two original studies. Considering the role of ABO blood groups on the hemostatic process and thrombus formation, special attention should be given to pregnant patients carrying the AB blood group in order to prevent the syndrome and improve prognosis.     

On the mechanism behind the association between ABO blood groups and gastric carcinoma

It has been hypothesized that the mechanisms behind the association between blood group A and gastric carcinoma is that the carcinoma cells produce an antigen immunologically related to blood group A, which particularly in O-individuals may have a protective effect by preventing the growth and spread of the tumour. The hypothesis predicts that O-individuals would have a longer survival time than A-individuals and that eventually the protective effect in blood group O would be somewhat stronger in women with multiple pregnancies. The results showed a significantly lower frequency of blood group O in females and a tendency towards a longer survival time in O-individuals among gastric cancer patients, but the relationship between blood group O and number of children was not in the expected direction. Thus the observations gave only partial support for the hypothesis that the association between ABO blood groups and gastric carcinoma is dependent on the antigenicity of the neoplasm. The data showed a significantly higher prevalence of gastric carcinoma and a lower average survival time in male patients.     

Zur Verbreitung der ABO-Blutgruppen in der Bevölkerung Nordthailands

2048 subjects in North Thailand were examined for AB0 blood groups. A control group representative of the population of the provinces of Chiengmai and Lampun was formed of 382 examinees and 3403 blood donors.The distribution of AB0 groups in this population is similar to that of Central Thailand. Some ethnic groups show significant deviations: The Miao tribe, originating in South China, has a much higher frequency of B. There was a significant reduction in gene A and B in the younger generation of this tribe. The Thai Yong, people who migrated to North Thailand from Yunnan in the 19th century, show an AB0 distribution similar to Chinese in Yunnan. They differ significantly from the Northern Thai. There is also a difference in the distribution of -thalassaemia and hemoglobin E between these two groups.Male leprosy patients showed an excess of group A which was not present in female patients. The percentage of severely ill patients was much higher in the males. Differentiation into lepromatous and tuberculid forms is not available. Among 108 people who had suffered from smallpox approximately 20 years ago there was an excess of groups 0 an B in comparison to the control group.
