To determine if intestinal helminths and the CD23/nitric oxide pathway had an influence on liver size, we conducted a cross-sectional study on 438 patients with confirmed P. falciparum malaria admitted at the Hospital for Tropical Diseases in Bangkok. For all patients the liver size was measured as number of centimeters below the rib cage, a stool examination was conducted, and CD23 and reactiv...

BACKGROUND Intestinal helminthiasis is a debilitating parasitic disease found in many parts of Uganda including Luweero district. In the district, the disease causes as high as 9% morbidity in children below five years. There was very scanty district information on the disease based mainly on hospital records despite this figure. The current study was carried out to provide data to plan for its...

Helminths have evolved to become experts at subverting immune surveillance. Through potent and persistent immune tempering, helminths can remain undetected in human tissues for decades. Redirecting the immunomodulating "talents" of helminths to treat inflammatory human diseases is receiving intensive interest. Here, we review therapies using live parasitic worms, worm secretions, and worm-deriv...

BACKGROUND Helminth infection and malaria remain major causes of ill-health in the tropics and subtropics. There are several shared risk factors (e.g., poverty), and hence, helminth infection and malaria overlap geographically and temporally. However, the extent and consequences of helminth-Plasmodium co-infection at different spatial scales are poorly understood. METHODOLOGY This study was c...

Tissue invasive helminth infections and tuberculosis (TB) are co-endemic in many parts of the world and can trigger immune responses that might antagonize each other. We have previously shown that helminth infections modulate the Th1 and Th17 responses to mycobacterial-antigens in latent TB. To determine whether helminth infections modulate antigen-specific and non-specific immune responses in ...

BACKGROUND It has been suggested that the proliferative capacity of cells from individuals with HIV or both HIV and helminth infections is attenuated and cytokine production is dysregulated. This study describes peripheral blood mononuclear cell proliferation capacity and cytokine profile from individuals with HIV or both HIV and helminth infections in South Africa. METHODS Forty HIV-infected...

BACKGROUND Helminth co-infection in humans is common in tropical regions of the world where transmission of soil-transmitted helminths such as Ascaris lumbricoides, Trichuris trichiura, and the hookworms Necator americanus and Ancylostoma duodenale as well as other helminths such as Schistosoma mansoni often occur simultaneously. METHODOLOGY We investigated whether co-infection with another h...

BACKGROUND Helminth infections and allergies are associated with TH2 responses. Whereas the development of TH2 responses and allergic disorders in pediatric populations has been examined in affluent countries, no or little data exist from low income regions of the world. The aim of this study is to examine factors influencing the development of TH2 responses of children born in areas endemic fo...

The economic, physiological and immunological costs of endo-parasitism are documented to be higher in poultry with greater parasite intensities and diversity. The current study was undertaken to determine the effects of helminth burden in domestic guinea fowls at quantified natural infestation levels on body condition, haematological profile and spleen morphometrics. We hypothesized that the sp...

BACKGROUND The incidence and hematological effects of helminth infection during pregnancy were investigated among pregnant women in Isiala, Mbano, Southeast Nigeria. METHODS Totally 282 pregnant women were enlisted for the study between October 2011 and September 2012. Stool samples were examined for intestinal helminths using formalin-ether sedimentation technique. Hemoglobin (Hb) and Packed...
