Abstract Identification of risk factors for contracting and developing serious illness following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is of paramount interest. Here, we performed a retrospective cohort analysis of all Danish individuals tested for SARS-CoV-2 between 27 February 2020 and 30 July 2020, with a known ABO and RhD blood group, to determine the influence of common blood groups on virus susceptibility. Distribution of blood groups was compared with data from nontested individuals. Participants (29% of whom were male) included 473 654 individuals tested for SARS-CoV-2 using real-time polymerase chain reaction (7422 positive and 466 232 negative) and 2 204 742 nontested individuals, accounting for ∼38% of the total Danish population. Hospitalization and death from COVID-19, age, cardiovascular comorbidities, and job status were also collected for confirmed infected cases. ABO blood groups varied significantly between patients and the reference group, with only 38.41% (95% confidence interval [CI], 37.30-39.50) of the patients belonging to blood group O compared with 41.70% (95% CI, 41.60-41.80) in the controls, corresponding to a relative risk of 0.87 (95% CI, 0.83-0.91) for acquiring COVID-19. This study identifies ABO blood group as a risk factor for SARS-CoV-2 infection but not for hospitalization or death from COVID-19.

INTRODUCTION:Existing evidence on clinical and economic effectiveness of one long-acting injectable antipsychotic (LAI) versus another in successful management of schizophrenia is scarce. The study was conducted to compare all-cause inpatient healthcare utilization and associated costs among Medicaid patients with schizophrenia who initiated LAIs.METHODS:This retrospective cohort analysis used the Truven Health Analytics MarketScan® Medicaid claims database. Schizophrenia patients >18 years with at least one claim for one of the following LAI were identified between 1 January 2013 and 30 June 2014 (identification period): aripiprazole, fluphenazine, haloperidol, paliperidone palmitate, and risperidone. The first day of initiating an LAI was considered the index date. Patients were followed for 1 year from index date. Logistic and general linear regression models were used to estimate risk of inpatient hospitalization and associated costs during follow up.RESULTS:Of the identified Medicaid patients with schizophrenia, 1,672 (36.7 percent) initiated an LAI: 44.0 percent received paliperidone, 26.4 percent haloperidol, 13.8 percent risperidone, 9.2 percent aripiprazole, and 6.6 percent fluphenazine. With the aripiprazole cohort as the reference group, the odds of having any inpatient hospitalizations were significantly higher in haloperidol [Odds Ratio, OR (95 percent Confidence Interval, CI): 1.51 (1.05 - 2.16)] and risperidone [OR (95 percent CI): 1.58 (1.07 - 2.33)] cohorts. Fluphenazine and paliperidone palmitate cohorts also had higher risk of having any inpatient hospitalizations compared with aripiprazole, but the differences were not statistically significant (p>.05). Among LAI initiators with any inpatient hospitalizations, the adjusted mean inpatient costs were lowest in the aripiprazole cohort (USD25,616), followed by haloperidol (USD30,811), paliperidone (USD30,833), risperidone (USD31,584), and fluphenazine (USD37,338), although differences were not statistically significant.CONCLUSIONS:Our study findings highlight the value of aripiprazole in reducing inpatient hospitalizations and associated costs among patients with schizophrenia. However, our study is limited as our results are reflective of a multi-state Medicaid population. Future studies are warranted to confirm the results in non-Medicaid patient populations.

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.

Objective: The present study investigates the seroconversion time course of the IgG antibody against SARS-CoV-2 and ascertains whether its levels change according to the patient’s ABO blood group. Method: A total of 36,003-convalescent plasma (CP) donations of 12,315 Turkish Red Crescent CP donors were analyzed. The ABO blood group of the CP donors was determined by Gel Centrifugation; and IgG was measured using the Euroimmun anti-SARS-CoV-2 ELISA. The differences in the distributions of mean IgG ratios among the different ABO blood groups were analyzed with One-Way ANOVA and Independent Samples T-test. Results: Among the CP donors, 98.4% were male. An antibody response to SARS-CoV-2 was noted-although in a few CP donors- on the 244th day, and a significant association between the ABO blood groups and the mean IgG ratios was noted (p: 0.001). The highest (mean±SD) antibody level was observed in the AB blood group (39.5±15.7), followed by the B (37.9±11.5) and the A blood groups (36.6±10.7), while the lowest value was recorded in the O blood group (34.4±11.5). Significant differences between all paired groups were noted in pairwise comparisons. The Rh (-) blood group (37.4±13.6) had a significantly higher antibody level than the Rh (+) blood group (36.3±11.2) (p: 0.005). Conclusion: An antibody response to SARS-CoV-2 was noted in a CP donor on the 244th day. The average IgG ratios were higher in the CP donors with the AB blood group, but lower in the O blood group. These results may be considered a valuable indication of the effectiveness of CP therapy used for the treatment of COVID-19 patients with clinically relevant blood types.

Introduction: Coronavirus disease 2019 (COVID-19) disease severity differs widely due to numerous factors including ABO gene-derived susceptibility or resistance. The objective of this study was to investigate the association of the ABO blood group and genetic variations of the ABO gene with COVID-19 severity in a heterogeneous hospital population sample from the United Arab Emirates, with the use of an epidemiological and candidate gene approach from a genome-wide association study (GWAS).Methods: In this cross-sectional study, a total of 646 participants who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were recruited from multiple hospitals and population-based (quarantine camps) recruitment sites from March 2020 to February 2021. The participants were divided into two groups based on the severity of COVID-19: noncritical (n = 453) and critical [intensive care unit (ICU) patients] (n = 193), as per the COVID-19 Reporting and Data System (CO-RADS) classification. The multivariate logistic regression analysis demonstrated the association of ABO blood type as well as circulating anti-A antibodies and anti-B antibodies as well as A and B antigens, in association with critical COVID-19 hospital presentation. A candidate gene analysis approach was conducted from a GWAS where we examined 240 single nucleotide polymorphisms (SNPs) (position in chr9: 136125788-136150617) in the ABO gene, in association with critical COVID-19 hospital presentation.Results: Patients with blood group O [odds ratio (OR): 0.51 (0.33, 0.79); p = 0.003] were less likely to develop critical COVID-19 symptoms. Eight alleles have been identified to be associated with a protective effect of blood group O in ABO 3'untranslated region (UTR): rs199969472 (p = 0.0052), rs34266669 (p = 0.0052), rs76700116 (p = 0.0052), rs7849280 (p = 0.0052), rs34039247 (p = 0.0104), rs10901251 (p = 0.0165), rs9411475 (p = 0.0377), and rs13291798 (p = 0.0377).Conclusion: Our findings suggest that there are novel allelic variants that link genetic variants of the ABO gene and ABO blood groups contributing to the reduced risk of critical COVID-19 disease. This study is the first study to combine genetic and serological evidence of the involvement of the ABO blood groups and the ABO gene allelic associations with COVID-19 severity within the Middle Eastern population.

Purpose: to assess the frequency of ABO and Rh blood groups among Saudi and non-Saudi healthy blood donors and to compare between them. Methods: A retrospective study was conducted; in Makkah City, Saudi Arabia. It included 15,365 participants of 44 nationalities who have attended the blood bank of King Abdul Aziz Hospital. The collected data were age, sex, nationality, ABO, and Rhesus blood groups.  Results: 46.8 % of the participants were O, 28.8 % A, 19.5 % B, and 4.9% AB. The nationalities with a higher frequency of blood group O were Saudi, Mauritanian, Yemeni, Thai, Malian, Sudanese, Jordanian, Indian, Moroccan, Somali, Malaysian, Indonesian, Myanmar, Nigerian, Pakistani, Bangladeshi, Algerian, Djibouti, Burkinabe, Eritrean, Ghanaian, Bahraini, Bosnian, Canadian, Gambian, Iraqi, and Sri Lankan. Those with a higher frequency of blood group A were Turkish, Palestinian, Syrian, Lebanese, Egyptian, Afghan, Chadian, French, Tunisian, Cameroonian, Ethiopian, and British.  Those with a higher frequency of B were Nigerien, American, Nepalese, and two nationalities with higher AB frequency Filipino and Chinese. 91.6 % of all populations were Rh-positive, and 8.4% were Rh-negative. The Saudi participants were like some nationalities and differed from others. Conclusion:  In Makkah city, the higher frequency of ABO blood group in Saudi and non -Saudi people is O followed by A, then B, and AB.  The Rh-positive is predominant, and 8.4% of the participants are negative. The ABO and Rh blood groups' identifications are essential for providing suitable blood storage for individuals in need.

Objective: This meta-analysis comprehensively evaluated the association between ABO blood group and the risk of preeclampsia (PE).Design: Systematic review and meta-analysis.Data sources: PubMed, Web of Science, and ScienceDirect databases from their inception to September 23, 2020.Methods: Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were obtained through random-effects and fixed-effects models according to heterogeneity. Meta-regression analysis was applied to explore the source of heterogeneity. We conducted a subgroup analysis by the publication year, study design, state, and Newcastle-Ottawa Scale (NOS) score. In addition, we calculated the rate of each ABO blood group in PE by total pooled effects.Results: A total of 12 articles with 714,153 patients were included in our analysis. Compared with people without PE (control group), the O blood group presented a lower risk of PE (OR 0.95, 95% CI 0.93–0.97). The AB (OR 1.46, 95% CI 1.12–1.91) blood group presented a higher risk. However, the total pooled OR and 95% CI for the A (OR 1.02, 95% CI 0.90–1.16) and B (OR 1.02, 95% CI 0.98–1.05) blood groups were not significant. The funnel plot and linear regression equation showed that there was no publication bias for the O, A, or B blood groups (all P > 0.05). However, the funnel plot and linear regression equation for the AB blood group were obviously asymmetric (P < 0.05), and the publication bias persisted even after the trim-and-fill method was applied (P < 0.05). Multivariable meta-regression analysis did not find a specific source of heterogeneity. The A blood group showed an association with early-onset PE (OR 0.53, 95% CI 0.33–0.83), and the other blood groups showed no significant differences. In PE, the rates of the O, A, B, and AB blood groups decreased gradually (0.39, 0.33, 0.19, 0.07).Conclusion: These findings suggest that pregnant women with AB blood group are more likely to develop PE, and more attention should be paid to AB blood group whose blood pressure is high but not sufficient to diagnose PE.Systematic Review Registration: Prospero CRD42021227930.
