(−7402 T/G and -4729G/A) condition susceptibility to pediatric severe malarial anemia but not circulating IL-13 levels
Okeyo, WA; Munde, EO; Okumu, W; Raballah, E; Anyona, SB; Vulule, JM; Ong’echa, JM; Perkins, DJ; Ouma, C (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 ... -
Bacteremia in Kenyan children presenting with malaria
Were, T; Davenport, GC; Hittner, JB; Ouma, C; Vulule, JM; Ong'echa, JM; Perkins, DJ (American Society for Microbiology, 2011-02-01)Since the etiologies and clinical outcomes of bacteremia in children with Plasmodium falciparum infections, particularly in areas of holoendemic malaria transmission, are largely unexplored, blood cultures and comprehensive ... -
Functional promoter haplotypes of interleukin-18 condition susceptibility to severe malarial anemia and childhood mortality
Anyona, SB; Kempaiah, P; Raballah, E; Ouma, C; Were, T; Davenport, GC; Konah, SN; Vulule, JM; Hittner, JB; Gichuki, CW; Ong'echa, JM; Perkins, DJ (Pub Med Central, 2011-12)Severe malarial anemia (SMA) is a leading cause of morbidity and mortality in children residing in regions where Plasmodium falciparum transmission is holoendemic. Although largely unexplored in children with SMA, ... -
Functional promoter haplotypes of interleukin-18 condition susceptibility to severe malarial anemia and childhood mortality.
T, Were,; CW, Gichuki; Ong'echa, JM; Ouma, Collins; Anyona, SB; Kempaiah, P; Raballah, E; Davenpor, GC; Konah, SN; Vulule, JM; Hittner, James B; Perkins, DJ (PubMed, 2012)Severe malarial anemia (SMA) is a leading cause of morbidity and mortality in children residing in regions where plasmodium falciparum transmission is holoendemic. Although largely unexplored in children with SMA, ... -
Parasitemia, anemia, and malarial anemia in infants and young children in a rural holoendemic Plasmodium falciparum transmission area.
Were, T; Ong'echa, JM; Keller, CC; Ouma, C; Otieno, Richard O; Lewis, Z L; Ochie, D; Slingluff, JL; Mogere, S; Ogonji, GA; Orago, AS; Vulule, JM; Kaplan, SS; Day, RD; Perkins, DJ (American Journal of Tropical Medicine and Hygiene, 2005)Malarial anemia (MA) is a multifactorial disease for which the complex etiological basis is only partially defined. The association of clinical, nutritional, demographic, and socioeconomic factors with parasitemia, ... -
Polymorphic variability in the 3' untranslated region (UTR) of IL12B is associated with susceptibility to severe anaemia in Kenyan children with acute Plasmodium falciparum malaria
Ong'echa, JM; Raballah, EO; Kempaiah, PM; Anyona, SB; Were, T; Davenport, GC; Konah, S; Vulule, JM; Ouma, C; Hittner, JB; Perkins, DJ (Pub Med Central, 2011-08)BACKGROUND: 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 ... -

Polymorphic Variability in the Interleukin (IL)-1Beta Promoter Conditions Susceptibility to Severe Malarial Anemia and Functional Changes in IL-1Beta Production
Otieno, Micheal F; Ouma, C; Davenport, GC; Awandare, GA; Keller, CC; Were, T; Vulule, JM; Martinson, J; Ong'echa, JM; Ferrell, RE; Perkins, DJ (PubMed, 2012)Interleukin (IL)-1beta is a cytokine released as part of the innate immune response to Plasmodium falciparum. Because the role played by IL-1beta polymorphic variability in conditioning the immunopathogenesis of severe ... -
Reduced Systemic Bicyclo-Prostaglandin-E2 and Cyclooxygenase-2 Gene Expression are Associated with Inefficient Erythropoiesis and Enhanced Uptake of Monocytic Hemozoin in Children with Severe Malarial Anemia
Anyona, SB; Kempaiah, P; Raballah, E; Davenport, GC; Were, T; Konah, SN; Vulule, JM; Hittner, JB; Gichuki, CW; Ong’echa, JM; Perkins, DJ (Pub Med Central, 2012-08)In holoendemic Plasmodium falciparum transmission areas, severe malaria primarily occurs in children <48 mos. and manifests as severe malarial anemia [SMA; hemoglobin (Hb)<6.0 g/dL]. Induction of high levels of prostaglandin-E2 ... -
Suppressed circulating bicyclo-PGE2 levels and leukocyte COX-2 transcripts in children co-infected with P. falciparum malaria and HIV-1 or bacteremia.
Anyona, SB; Kempaiah, P; Davenport, GC; Vulule, JM; Hittner, JB; Ong’echa, JM; Perkins, DJ (Biochemical and biophysical research communications, 2013)In holoendemic Plasmodium falciparum transmission regions, malarial anemia is a leading cause of childhood morbidity and mortality. Identifying biomarkers of malaria disease severity is important for identifying at-risk ...
