WOS: 000502637300015 PubMed: 30461381 Objective: The aim of this study is to investigate whether there is a correlation between AB0 blood group antigens and Rhesus factor and lower urinary tract symptoms (LUTS). Material and methods: A total of 556 male patients applying to our clinic with LUTS complaints from April 2012-2015 and complying with the study criteria were included in the study. The patients were divided into two groups as those with (Group 1; n=283) and without LUTS (Group 2; n=273) complaints. The effect of blood groups on LUTS complaints was compared using univariate logistic regression analyzes. Results:According to AB0 blood groups, blood groups A (56.7%) and AB (56.9%) were most common in the LUTS group. But 0 blood group (44.1%) was the least common. According to rhesus factor, the incidence of LUTS in Rh (+), and Rh (-) groups were 48.9%, and 66.7%, respectively. Compared to 0 blood group, the LUTS incidence was 1.65, and 1.66 times higher for individuals with blood groups A, and AB, respectively. The same risk increased 2.09 times for individuals with Rhesus factor negative. Conclusion: This study identified a correlation between AB0 blood group and Rhesus factor and LUTS. The risk of LUTS risk increased in individuals with blood group A Rh (). Additionally there was a clear risk increase observed for AB blood group, though this did not reach statistical significance.

Background: The ABO blood group and Rhesus (Rh) factor remain the most important blood group in transfusion medicine. Knowledge of ABO and rhesus blood group distribution within a population is indispensable for transfusion medicine, clinical and marriage counselling. Aims and Objectives: The objectives of this study were to provide data and compare the pattern of ABO and rhesus blood group distribution between a homogenous and a heterogenous population. Material and Methods: Blood was collected from 352 University students representing a heterogenous population and 235 primary school pupils in a local community representing homogenous population. The ABO and rhesus blood groups were determined using white tile and agglutination methods. Results: Among the 352 and 235 individuals studied in UNN and HFNP, blood groups O had the highest frequency with 54.80% and 51.06% respectively while blood group AB had the least frequency of 4.50% and 3.40% in UNN and HFNP respectively. Rhesus positive had the highest frequency of 88.63% and 95.33% while rhesus negative had the frequencies of 11.35% and 4.68% in UNN and HFNP respectively. Rhesus negative was highest among females in UNN 26 (7.37%) while males had the highest rhesus negative 7 (2.98%) in HFNP. In both study populations, there was no significant difference in ABO and rhesus blood group distribution between the males and females (P > 0.05). Conclusions: A homogenous population is associated with low prevalence of rhesus negative compared to a heterogenous population.

Background: The distribution of ABO and rhesus (Rh) blood groups has been reported to be different in several world populations. There have been few studies about blood groups among Libyan population. Aims: The study aims to determine the distribution and frequency of ABO and Rh blood groups among Libyan population in Bani Waleed city. Subjects and Methods: The study group had included 344 participants of both genders aged between 15 and 80 years. Blood samples were collected for ABO and Rh blood group analysis from September to December 2018. Results: The percentage of male participants was 55.8% and 48.2% were female. The highest percentage (30.2%) were among the age group of 23–32 years. O blood group was the most common (43.6%), followed by A (31.7%), B (17.7%), and finally, AB blood group (7.0%). The percentage of Rh positive (Rh+) was 72.2% and of Rh negative (Rh−) was 23.8%. Moreover, the prevalence of ABO with Rh+ was 33.4%, 27.6%, 11.3%, and 4.7% for O+, A+, B+, and AB+, respectively. The prevalence of ABO with Rh− was 9.9%, 6.11%, 4.1%, and 2.6% for O−, B−, A−, and AB−, respectively. Conclusion: The distribution of ABO blood group in the present study is ordered of O > A> B > AB with majority of Rh+ and higher frequencies of Rh−. The findings of this study will contribute in health services and use them as database to know detailed information of blood types such as for blood bank and blood transfusion and also to be used in population studies.

Introduction Although several studies have investigated the relationship between ABO blood group and medical diseases, few reports have explored the association with oral diseases, including periodontal disease (PD). Aim The aim of this literature review was to assess the association between the ABO blood grouping and PD. Methods We searched PubMed and Google Scholar databases using the following terms in different combinations: “ABO blood group,” “periodontitis,” “aggressive periodontitis (AP),” “risk factor,” and “Rhesus factor.” Databases were searched for articles published from 1977 to August 2016. Titles and abstracts of articles were screened for English-language papers describing clinical studies, case reports, or retrospective studies of oral health status in patients with different ABO blood groups. Letters to the editor, historic reviews, and articles including unpublished data were excluded. Reference lists of included studies were reviewed for additional original and review studies. Results We identified eight articles describing studies of the relationship between ABO blood groups and PD. The findings suggested a possible genetic basis in the association of the blood group AB with AP. Four studies showed that chronic periodontitis was more common among patients with blood group O. Conclusion ABO blood subgroup and Rhesus factor could constitute risk predictors in the development of PD.

Objective: to improve the diagnosis of fetal hemolytic disease. Subjects and methods. A study group consisted of 42 pregnant women whose newborn infants had varying degrees of hemolytic disease. The women were divided into 3 subgroups according to the severity of neonatal hemolytic disease: 1) pregnant women whose neonates were born with severe hemolytic disease (n = 14); 2) those who gave birth to babies with moderate hemolytic disease (n = 11); 3) those who delivered infants with mild hemolytic disease (n = 17). A comparison group included 42 pregnant women whose babies were born without signs of hemolytic disease. Curvesfor blood flow velocity in the middle cerebral artery were analyzed in a fetus of 25 to 39 weeks’ gestation. Results. The peak systolic blood flow velocity was observed in Subgroup 1; however, the indicator did not exceed 1.5 MoM even in severe fetal anemic syndrome. The fetal middle artery blood flow velocity rating scale was divided into 2 zones: 1) the boundary values of peak systolic blood flow velocity from the median to the obtained midscore; 2) the boundary values of peak systolic blood flow velocity of the obtained values of as high as 1.5 MoM. Conclusion. The value of peak systolic blood flow velocity being in Zone 2, or its dynamic changes by transiting to this zone can serve as a prognostic factor in the development of severe fetal hemolytic disease.

BACKGROUND Haemolytic disease of the newborn secondary to Rhesus-D isoimmunisation contributes significantly to perinatal morbidity and mortality. There is a need for adequate counseling of pregnant women regarding the importance of detection of blood grouping and Rh typing during the antenatal period in order to prevent haemolytic disease of the newborn. The aim of this study is to estimate the prevalence of Rhesus-negative pregnancy in the antenatal women and evaluate the maternal and foetal outcome during the period of September 2014 to August 2015. MATERIALS AND METHODS All Rh-negative pregnant women who attended the Antenatal Clinic in Government Victoria Hospital were followed up till delivery and also postnatally regarding the maternal and foetal outcome. All the data was collected and results were analysed. RESULTS The prevalence of Rh-negative pregnancies in Government Victoria Hospital/Andhra Medical College, Visakhapatnam, was 4.268% out of 376 antenatal Rh-negative cases, 8 cases developed preeclampsia, 5 cases developed foetal growth restriction with severe oligoamnios, 2 cases associated with gestational diabetes mellitus and caesarean section was done in 120 cases. Regarding neonatal outcome, 366 were live born babies, 5 were early neonatal deaths and 5 were intrauterine deaths. CONCLUSION In our study, the prevalence of Rh-negative pregnancy is 4.268%. Despite the low prevalence of Rh-negative pregnancy, Rhisoimmunisation remains a determining factor responsible for perinatal morbidity.

Background AB0 blood groups and Rhesus factor expression have been associated with carcinogenesis, response to treatment and tumor progression in several malignancies. The aim of the present study was to test the hypothesis that AB0 blood groups and Rhesus factor expression are associated with clinical outcome in patients with epithelial ovarian cancer (EOC). Methods AB0 blood groups and Rhesus factor expression were evaluated in a retrospective multicenter study including 518 patients with EOC. Their association with patients’ survival was assessed using univariate and multivariable analyses. Results Neither AB0 blood groups nor Rhesus factor expression were associated with clinico-pathological parameters, recurrence-free, cancer-specific, or overall survival. In a subgroup of patients with high-grade serous adenocarcinoma, however, blood groups B and AB were associated with a better 5-year cancer-specific survival rate compared to blood groups A and 0 (60.3 ± 8.6% vs. 43.8 ± 3.6%, p = 0.04). Yet, this was not significant in multivariable analysis. Conclusions AB0 blood groups and Rhesus factor expression are both neither associated with features of biologically aggressive disease nor clinical outcome in patients with EOC. Further investigation of the role of the blood group B antigen on cancer-specific survival in the subgroup of high-grade serous should be considered.

Aim: To investigate the role of ABO blood group and Rhesus factor as a predictor of outcome in patients undergoing radical cystectomy (RC) for non-metastatic urothelial carcinoma of the bladder. Materials and Methods: Data of 463 consecutive patients treated with RC between 1988 and 2003 were retrospectively analyzed. The effect on recurrence-free survival, and cancer-specific and overall mortality were assessed using the Kaplan-Meier and multivariable Cox regression methods. Results: Overall, 185 (41.3%), 190 (42.4%), 46 (10.3%) and 27 (6%) patients expressed O, A, B and AB phenotypes, respectively; 65 (14.5%) were Rhesus-negative. Median follow-up was 14.2 years (interquartile range=10.2-17.1 years). No individual blood group was associated with any clinicopathological characteristics whereas Rhesus-positive patients had a higher rate of pT4 disease (11% vs. 22%; p=0.02). ABO blood groups were not associated with outcomes. Rhesuspositive patients had an increased risk of shorter recurrencefree survival, and of cancer-specific and overall mortality compared to Rhesus-negative patients (all p

Background : Blood groups and phenylthiocarbamide (PTC) are the most studied genetic traits among human populations around the world. In most of these studies, PTC taste sensitivity was described as a bimodal autosomal trait inherited in a simple Mendelian recessive pattern. ABO blood group is the most studied blood groups followed by Rhesus factors (Rh) and haemoglobin variants. Information from the study of these traits is useful to biologists, geneticists, anthropologists and clinicians. No information on the prevalence and gene frequencies of these traits among a population from Nigeria. Aim : This study presents information on the prevalence and gene frequencies of PTC taste sensitivity, ABO blood group and Rhesus factor, and Haemoglobin variants from male and female Nigerians examined. Subjects and methods : A total of 232 (51.33%) male and 220 (48.67%) female Nigerians participated in this study. Filter paper impregnated with 81.25 mg/L of saturated solution of PTC wasused to determine PTC tasters, while blood group phenotypes, Rhesus factor and haemoglobin types were determined by classical method. Hardy–Weinberg method was used to determine allelic frequencies and graphpad 5 computer software was used for the data processing. Results : The percentage frequency for non tasters of PTC was 29.42% with allele frequency t= 0.5424. There were more male (33.62%) non tasters than female (25.0%), but more female (75.0%) tasters than male (66.38%). This observation was statistically significant (p= 0.0444). Our findings support the bimodal inheritance of PTC taste sensitivity among Nigerians. Overall trend of ABO blood group was O > B >A > AB. This same trend was observed for females but differed for males (O> B = A> AB). O blood group was the highest while AB group was the least among studied Nigerians in both genders. The distribution pattern did not differ significantly (p= 0.1406) from those expected under Hardy–Weinberg Law. 93.14% of the studied population was Rh+ (DD and Dd) and there were more Rh+ males than females but more Rh females than males. The proportions and distributions of Rh factor among studied population did not show statistical significance (X2= 0.6047, df = 1, P = 0.4624). The overall allele frequency of the blood group as computed according to Hardy–Weinberg Law is r = 0.8201, q= 0.0977 and p= 0.0822. Similar trend in allele frequency was observed for both genders. The allele frequency for Rh+ (D) is 0.7381 and Rh (d)= 0.2619. This trend is also similar in both sexes. Among the six haemoglobin variants common to Nigerians CC was not detected in our study. The other five were observed in the order AA (76.55%)> AS (20.35%)> AC (1.99%) > SS (0.66%) >SC (0.44%). The overall allele frequency was A =0.8772, S =0.1106, C = 0.0122. Conclusion : The findings from this study provide information on the studied traits. It will provide background information for further studies and will be useful to clinicians, geneticists and anthropologists with respect to blood transfusion, marriage counseling and population studies.

The aim of this research is to search for same connection between blood type systems ABO and Rhesus factor and haemophilia A. The study was conducted on 91 male patients with haemophilia A. The results of the blood type system ABO are compared to those of the Bulgarian population. There is a significantly higher frequency of O blood type among patients - 54,94% against 31,67% (p

Objectives: The study was conducted to emphasize the sensitivity and specificity of dental pulp in identifying the ABO Blood group, Rhesus factor and also to emphasize the role of dental pulp in forensic odontology to identify the deceased individual. Materials and Methods: The study was conducted on 60 patients. The samples obtained from finger-prick method from those 60 patients were considered as control and the samples obtained from the pulp were considered as case. The blood grouping, Rhesus typing for capillary blood drawn by finger prick was done by slide-agglutination method and the blood grouping, Rhesus typing for extracted dental pulp was done by absorption-elution method. Results: Fifty seven teeth out of sixty showed positive results. Blood group elicited from capillary blood done by slide-agglutination method matched with that of the pulpal blood group elicited by absorption-elution method. Three showed negative results. Conclusion: As the teeth are the hardest, most stable biological material, resist adverse environmental conditions and the pulpal tissue inside the teeth is well protected, the blood group antigen from pulp remains stable for long. Thus, the high potential value of dental pulp tissue is highlighted in this study.
