Oral Contraceptive Types in Relation to ABO Blood Groups Among Saudi Women of Different Reproductive Age Groups and Impact on Venous Thromboembolism

Saudi women have recently started using oral contraceptives (OCs), which has led to risk of venous thromboembolism (VTE). The risk varies with the type of OC generations used, and with OC use the risk for VTE increases by 2- to 6-fold. This study evaluated the effect of OC types in relation to ABO blood group on the risk of VTE among Saudi women. Thrombin generation (TG) was measured in the plasma of the women in the presence and absence of platelet rich plasma, platelet poor plasma and thrombomodulin or activated protein C. OC usage increased TG parameters ETP and Peak height by 9.81% and 16.04%, respectively. An increased risk of VTE was seen among women on third generation OCs as compared to those on second generation products. Within OC generations, we found that for women using fourth generation OCs, their ETP increased by 36.18% as compared to those using second generation and by 6.07% in those using third generation compared to those using second generation. There was significant difference with respect to ABO blood groups and OC generation types, but larger sample size is required. Women who are 40 years and older and using third generation OC had a higher risk of having thrombosis (11.84%), as compared to those using second generation OC (8.79%) and to those using fourth generation OC (5.03%). An association between different OC groups and non-O blood group in thrombosis generation was noted. TG parameters were significantly increased in relation to BMI when comparing to OC users versus non-users. In addition, inhibition of TG parameters in the presence of recombinant human thrombomodulin (TM) and activated protein C (APC) were significantly increased.

Abstract Background: Numerous studies have demonstrated that patients with non-O blood groups have higher risk for venous thromboembolism than those with O blood group. However, it has remained unknown about the effect of ABO blood groups on warfarin dose requirements in patients receiving anticoagulation in Chinese Han population. The study aimed to investigate the influence of ABO blood groups on warfarin dose requirements in Chinese Han population. Methods: A retrospective study was conducted in the First Affiliated Hospital of Shantou University Medical College in Southern China. Three hundreds and 58 patients with confirmed diagnosis of deep venous thromboembolism and atrial fibrillation were included. Frequency of blood groups and warfarin dose requirements were determined. Results: Of 358 patients with deep venous thromboembolism and atrial fibrillation, 111 patients had blood group A (31.01%), 104 patinets had blood group B (29.05%), 20 patients had blood group AB (5.59%), and 123 patients had blood group O (34.36%). The patients with O blood group had a lower warfarin dose requirements compared with those with A, B and AB blood group. Conclusion: Our study showed that patients with non-O blood groups require higher doses of warfarin.

Background: ABO blood types are scientifically proved to be associated with the risk of venous thromboembolism (VTE), but data is lacking in the Saudi population. Aims: We aimed to investigate the association between ABO blood types and VTE, to explore potential interactions between ABO blood type with sex and obesity status. Methods: This was a retrospective study with a total of 998 patients, who were admitted with venous thromboembolism at our tertiary care hospital, between January 2010 and January 2018. Demographic and clinical data were collected. We used chi-square tests to assess the association between ABO blood group and the development of VTE. It was decided that the test will be considered significant if the p-value is <0.05. Results: Out of 998 VTE patients, 506 of patients were excluded, because their ABO blood group was not tested. Therefore, 492 patients were qualified as study subjects, of whom 66% of patients had DVT, 23% of patients had pulmonary embolism. Most of them had provoked VTE. Female patients constituted the majority of the study subjects (82.5%). Sample distribution appeared that O blood group was present in 34.1% of all VTE patients, while non-O-blood groups were present in 66% of them. Overall, there was a non-significant difference between VTE in patients with non-O blood type compared to O blood type (p=0.268). Conclusions: Non-O-blood groups (A, B, AB) are the most common blood types in Saudi patients with VTE. There is no statistically significant association between ABO blood groups, gender, and obesity status. Disclosures No relevant conflicts of interest to declare.

AbstractFactor V gene polymorphisms were investigated to detect components that may contribute to the activated protein C (APC) resistance phenotype in patients with venous thromboembolism. A specific factor V gene haplotype (HR2) was defined by six polymorphisms and its frequency was found to be similar in normal subjects coming from Italy (0.08), India (0.1), and Somalia (0.08), indicating that it was originated by ancestral mutational events. The relationship between the distribution of normalized APC ratios obtained with the functional assay and haplotype frequency was analyzed in patients heterozygous for factor V R506Q (factor V Leiden). The HR2 haplotype was significantly more frequent in patients with ratios below the 15th percentile than in those with higher ratios or in normal controls. Moreover, the study of 10 patients with APC resistance in the absence of the factor V R506Q mutation showed a 50-fold higher frequency of HR2 homozygotes. The HR2 haplotype was associated with significantly lower APC ratios both in patients with venous thromboembolism and in age- and sex-matched controls. However, the two groups showed similar HR2 haplotype frequencies. Plasma mixing experiments showed that an artificially created double heterozygote for the factor V R506Q mutation and the HR2 haplotype had an APC ratio lower than that expected for a simple R506Q heterozygote. Time-course experiments evaluating the decay of factor V in plasma showed the normal stability of the molecule encoded by the factor V gene marked by the HR2 haplotype, which ruled out the presence of a pseudo-homozygous APC resistance mechanism. Our results provide new insights into the presence of factor V genetic components other than the factor V R506Q that are able to contribute to the APC resistance phenotype in patients with venous thromboembolism.

BACKGROUND: The development of periodontal diseases depends on the presence of causative microorganisms, host immunity and risk factors. Although variability present among the types of periodontal diseases, all are represented to a shared interaction between host and bacteria. ABO blood groups are the most investigated erythrocyte antigen system. However, limited investigations have been conducted to explore the alliance between ABO blood groups and periodontal diseases. AIM: Our purpose was to explore any possible association between the severity of chronic periodontitis with ABO blood groups and Rh factor. METHODS: A cross-sectional study was carried out on 205 patients out of 1126 generalised chronic periodontitis patients (GCP) who were referred to Al-Farabi Colleges, Riyadh, Saudi Arabia. They were categorized into; group I (mild), group II (moderate) and group III (sever). RESULTS: The patients with blood group O were at a greater risk to develop GCP irrespective of its severity, followed by those with blood group A, B, and AB. The dispensation of the Rh factor in all groups exhibited a significantly greater distribution of Rh positive. CONCLUSION: Genetic factors such as ABO blood group antigens may act as a risk influencer that affects the progression and severity of the chronic periodontitis.

Background Globally, studies have shown conflicting results regarding the association of blood groups with SARS CoV-2 infection. Objective To observe the association between ABO blood groups and the presentation and outcomes of confirmed COVID-19 cases. Design, setting, and participants This was a prospective cohort study of patients with mild-to-moderately severe COVID-19 infections who presented in the COVID-19 unit of Dhaka Medical College Hospital and were enrolled between 01 June and 25 August, 2020. Patients were followed up for at least 30 days after disease onset. We grouped participants with A-positive and A-negative blood groups into group I and participants with other blood groups into group II. Results The cohort included 438 patients; 52 patients were lost to follow-up, five died, and 381 completed the study. The prevalence of blood group A [144 (32.9%)] was significantly higher among COVID-19 patients than in the general population (p < 0.001). The presenting age [mean (SD)] of group I [42.1 (14.5)] was higher than that of group II [38.8 (12.4), p = 0.014]. Sex (p = 0.23) and co-morbidity (hypertension, p = 0.34; diabetes, p = 0.13) did not differ between the patients in groups I and II. No differences were observed regarding important presenting symptoms, including fever (p = 0.72), cough (p = 0.69), and respiratory distress (p = 0.09). There was no significant difference in the median duration of symptoms in the two group (12 days), and conversion to the next level of severity was observed in 26 (20.6%) and 36 patients (13.8%) in group I and II, respectively. However, persistent positivity of RT-PCR at 14 days of initial positivity was more frequent among the patients in group I [24 (19%)] than among those in group II [29 (11.1%)]. Conclusions The prevalence of blood group A was higher among COVID-19 patients. Although ABO blood groups were not associated with the presentation or recovery period of COVID-19, patients with blood group A had delayed seroconversion.

Background: The pattern and distribution of Haematological malignancies vary depending on age, sex and geographical location. Studies on the association between Haematological cancers and ABO blood types have been largely conflicting. The objective of our study was to determine the distribution of ABO blood groups among patients with Haematological malignancies and to correlate with age and gender. Materials and Methods: This was a chart based observational descriptive study involving the review of records of 85 patients with various Haematological malignancies in Father Muller Medical College Hospital for a period of two years from July 2017- June 2019. Age, gender, malignant condition, ABO and Rh blood group were collected for each case. Data was analyzed statistically by frequency and percentage. Results: The peak age incidence for various Haematological malignancies was in the fifth and sixth decades of life with a mean age of 47.The male to female sex ratio was almost 1:1. Majority of the patients were of the O blood group and an association of O blood group with various hematological malignancies with male preponderance was noted. Altogether, Leukemias were the most common Haematological malignancy observed in this study. Conclusion: The distribution, age and sex ratio of Haematological malignancies in our study was comparable to those reported by other authors with Acute Myeloid Leukemia (AML) being the most common Haematological malignancy in our environment. There was no significant association between Haematological cancers and ABO blood type of the patients, but probably individuals with O Rh positive blood group are more prone to

Background. Determination of the various ABO/Rh blood group distributions and their association with malaria infection has paramount importance in the context of transfusion medicine and malaria control. Methods. Facility based cross-sectional study was conducted from February to June, 2015, to assess ABO/Rh blood groups distribution and their association with asymptomatic malaria. A structured questionnaire was used to collect data. Blood grouping was done using monoclonal antibodies. Thin and thick blood films were examined for Plasmodium parasites. Data were analyzed using SPSS version 20.0. Results. A total of 416 blood donors participated with median age of 22±0.29 (median ± standard error of the mean). Distribution of ABO phenotypes, in decreasing order, was O (175, 42.1%), A (136, 32.7%), B (87, 20.9%), and AB (18, 4.3%). Most of them were Rh+ (386, 92.8%). The overall malaria prevalence was 4.1% (17/416). ABO blood group is significantly associated with malaria infection (P=0.022). High rate of parasitemia was seen in blood group O donors (6.899, P=0.003) compared to those with other ABO blood groups. Conclusion. Blood groups O and AB phenotypes are the most and the least ABO blood groups, respectively. There is significant association between ABO blood group and asymptomatic malaria parasitemia.
