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 ... -
Clinical chemistry profiles in injection heroin users from Coastal Region, Kenya
Were, Tom; Wesongah, Jesca O; Munde, Elly; Ouma, Collins; Kahiga, Titus M; Owuor, Francisca O; Kiarie, James N; Ahmed, Aabid A; Makokha, Ernest P; Budambula, Valentine (Biomed central, 2014-07-09)Background Although the co-burden of injection drug use and HIV is increasing in Africa, little is known about the laboratory markers of injection drug use and anti-retroviral treatment (ART) in Kenyan injection drug ... -
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 ... -
Hepatitis B virus sero-profiles and genotypes in HIV-1 infected and uninfected injection and Non-injection drug users from coastal Kenya
Webale, Mark K; Budambula, Valentine; Lihana, Raphael; Musumba, Francis O; Nyamache, Anthony K; Budambu, Nancy LM; Ahmed, Aabid A; Ouma, Collins; Were, Tom (BioMed Central, 2015-07-30)Background Information about HBV sero-markers, infection stages and genotypes in HIV-1 infected and uninfected injection and non-injection drug users (IDUs) in Kenya remains elusive. Methods A cross-sectional study ... -
HIV-1 protease inhibitor drug resistance in Kenyan antiretroviral treatment-naive and-experienced injection drug users and non-drug users
Budambula, Valentine; Musumba, Francis O; Webale, Mark K; Kahiga, Titus M; Owuor, Francisca O; Kiarie, James N; Sowayi, George A; Ahmed, Aabid A; Ouma, Collins; Were, Tom (BioMed Central, 2015-08-15)Background Although injection drug use drives antiretroviral drug resistance, the prevalence of protease inhibitor (PI) resistance among Kenyan IDUs remains undetermined. We, therefore, explored PI resistance mutations ... -

Budambula, Valentine; Musumba, Francis O; Webale, Mark K; Kahiga, Titus M; Owuor, Francisca O; Kiarie, James N; Sowayi, George A; Ahmed, Aabid A; Ouma, Collins; Were, Tom (BioMed Central, 2015-08-11)Background Although injection drug use drives antiretroviral drug resistance, the prevalence of protease inhibitor (PI) resistance among Kenyan IDUs remains undetermined. We, therefore, explored PI resistance mutations ... -
Natural monocytic acquisition of haemozoin and rantes polymorphisms: association with malarial disease outcomes and functional changes in children from Wester...
Were, Tom (2011-08-15)Plasmodium falciparum is an important cause of morbidity and mortality in children residing in holoendemic transmission areas largely from severe malarial anaemia (SMA). Although overproduction of inflammatory-derived ... -
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 ...
