(− 7402 T/G and-4729G/A) condition susceptibility to pediatric severe malarial anemia but not circulating IL-13 levels
Okumu, Wilson; Okeyo, Winnie A; Munde, Elly O; Raballah, Evans; Anyona, Samuel B; Vulule, John M; Ong’echa, John M; Perkins, Douglas J; Ouma, Collins (Bio Med Central, 2013)In holoendemic Plasmodium falciparum transmission areas such as western Kenya, severe malarial anemia [SMA, hemoglobin (Hb) < 6.0 g/dL, with any density parasitemia] is the most common clinical manifestation of severe ... -
Association between Fcγ receptor IIA, IIIA and IIIB genetic polymorphisms and susceptibility to severe malaria anemia in children in western Kenya
Munde, Elly O; Okeyo, Winnie A; Raballah, Evans; Anyona, Samuel B; Were, Tom; Ong’echa, John M; Perkins, Douglas J; Ouma, Collins (BioMed Central, 2017-04-20)Background Naturally-acquired immunity to Plasmodium falciparum malaria develops after several episodes of infection. Fc gamma receptors (FcγRs) bind to immunoglobulin G (IgG) antibodies and mediate phagocytosis of ... -
Functional Haplotypes of Fc gamma (Fcγ) receptor (FcγRIIA and FcγRIIIB) predict risk to repeated episodes of severe malarial anemia and mortality in Kenyan children
Ouma, Collins; Davenport, Gregory C; Garcia, Steven; Kempaiah, Prakasha; Chaudhary, Ateefa; Were, Tom; Anyona, Samuel B; Raballah, Evans; Konah, Stephen N; Hittner, James B; Vulule, John M; Ong’echa, John M; Perkins, Douglas J (Springer-Verlag, 2012-02-01)Development of protective immunity against Plasmodium falciparum is partially mediated through binding of malaria-specific IgG to Fc gamma (γ) receptors. Variations in human FcγRIIA-H/R-131 and FcγRIIIB-NA1/NA2 affect ... -
Haplotype of non-synonymous mutations within IL-23R is associated with susceptibility to severe malaria anemia in a P. falciparum holoendemic transmission area...
Munde, Elly O; Raballah, Evans; Okeyo, Winnie A; Ong’echa, John M; Perkins, Douglas J; Ouma, Collins (BioMed Central, 2017-04-20)Background Improved understanding of the molecular mechanisms involved in pediatric severe malarial anemia (SMA) pathogenesis is a crucial step in the design of novel therapeutics. Identification of host genetic ... -
HAPLOTYPES WITHIN NFKBIA PROMOTER ARE ASSOCIATED WITH SEVERE MALARIAL ANEMIA AND CIRCULATING IL-10 AND IP-10 LEVELS IN CHILDREN...
Munde, Elly O; Achieng, Angela O; Kisia, Lily E; Karim, Zachery S; Raballah, Evans O; Kempaiah, Prakasha; Ong'echa, John M; Ouma, Collins; Perkins, Douglas J (AMER SOC TROP MED & HYGIENE, 2017-11-01)HAPLOTYPES WITHIN NFKBIA PROMOTER ARE ASSOCIATED WITH SEVERE MALARIAL ANEMIA AND CIRCULATING IL-10 AND IP-10 LEVELS IN CHILDREN WITH PLASMODIUM FALCIPARUM MALARIA -
HAPLOTYPES WITHIN THE NFKB1 PROMOTER ARE ASSOCIATED WITH RISK OF SEVERE MALARIAL ANEMIA
Munde, Elly O; Karim, Zachary S; Onyambu, Frank G; Raballah, Evans O; Ong'echa, John M; Ouma, Collins; Kempaiah, Prakasha; Perkins, Douglas J (AMER SOC TROP MED & HYGIENE, 2015-10-01)Haplotypes within the NFKBI1 promoter are associated with risk of severe malaria anemia -
Hematological predictors of increased severe anemia in Kenyan children coinfected with Plasmodium falciparum and HIV‐1
Davenport, Gregory C; Ouma, Collins; Hittner, James B; Hittner, James B; Ouma, Yamo; Ong'echa, John M; Perkins, Douglas J (Wiley Subscription Services, Inc., A Wiley Company, 2010-04-01)Malaria and HIV-1 are coendemic in many developing countries, with anemia being the most common pediatric hematological manifestation of each disease. Anemia is also one of the primary causes of mortality in children ... -
Interleukin (IL)-13 promoter polymorphisms (-7402 T/G and-4729G/A) condition susceptibility to pediatric severe malarial anemia but not circulating IL-13 levels
Okumu, Wilson; Okeyo, Winnie A; Munde, Elly O; Raballah, Evans; Anyona, Samuel B; Vulule, John M; Ong’echa, John M; Perkins, Douglas J; Ouma, Collins (BioMed Central, 2013-12)In holoendemic Plasmodium falciparum transmission areas such as western Kenya, severe malarial anemia [SMA, hemoglobin (Hb) < 6.0 g/dL, with any density parasitemia] is the most common clinical manifestation of severe ... -
Polymorphic variability in the 3'untranslated region (UTR) of IL12B is associated with susceptibility to severe anaemia in Kenyan children with acute Plasmodium falc...
Ong'echa, John M; Raballah, Evans O; Kempaiah, Prakasha M; Anyona, Samuel B; Were, Tom; Davenport, Gregory C; Konah, Stephen; Vulule, John M; Ouma, Collins; Hittner, James B; Perkins, Douglas J (BioMed Central, 2011-08-06)Plasmodium falciparum malaria remains a leading cause of morbidity and mortality among African children. Innate immunity provides the first line of defence against P. falciparum infections, particularly in young children ...
