چکیده مقاله:

Background: Geographical distribution of ABO blood groups affects by race, ethnicity, migration and some infectious agents, such as Plasmodium species. P. falciparum is the major causative agent of death in malaria that can affect ABO blood group distribution in different populations. Therefore, the objective of the current study was to determine the effect of p. falciparum on ABO blood group distribution in Iran. Methods: The present study was conducted on the database of Iranian Blood Transfusion Organization (IBTO) in 30 provinces of the country about ABO and Rh blood groups of the people who referred to health centers from June 2011 to August 2012. Results: A total number of 2124560 individuals were referred to IBTO in 30 provinces. The highest and lowest rates of O blood group were observed in Sistan & Baluchestan (64.6%) and Lorestan (37.7%), respectively. P. falciparum was the most common species of malaria in Sistan & Baluchestan (53215) and the rarest infection agent in Semnan province (20). The results showed statistically significant relationship (p < 0.05) between prevalence of P. falciparum with O blood group, while this relationship for A blood group was not significant (p > 0.05). Conclusion: Our results revealed a significant relationship between prevalence of P. falciparum and geographical distribution of ABO blood. There was also found more susceptibility and risk to malaria infection and cerebral malaria in A blood group compared to other groups. In addition, this was the first comprehensive study on the ABO blood group system and Plasmodium infection in Iran.

The ABO blood group system and Plasmodium falciparum malaria.

In the century since the discovery of the ABO blood groups, numerous associations between ABO groups and disease have been noted. However, the selection pressures defining the ABO distributions remain uncertain. We review published information on Plasmodium falciparum infection and ABO blood groups. DNA sequence information dates the emergence and development of the group O allele to a period o...

Cytoadherence in paediatric malaria: ABO blood group, CD36, and ICAM1 expression and severe Plasmodium falciparum infection

As a leading cause of childhood mortality worldwide, selection pressure by Plasmodium falciparum continues to shape the human genome. Severe disturbances within the microcirculation result from the adhesion of infected erythrocytes to host receptors on monocytes, platelets, and endothelium. In this prospective study, we compared expression of all major host cytoadhesion receptors among Ugandan ...

Frequency of ABO blood group system polymorphisms in Plasmodium falciparum malaria patients and blood donors from the Brazilian Amazon region.

We investigated the ABO genotypes and heterogeneity of the O alleles in Plasmodium falciparum-infected and non-infected individuals from the Brazilian Amazon region. Sample collection took place from May 2003 to August 2005, from P. falciparum malaria patients from four endemic regions of the Brazilian Amazon. The control group consisted of donors from four blood banks in the same areas. DNA wa...
