BACKGROUND Hepatitis C virus (HCV) and Schistosoma mansoni are major causes of chronic liver disease (CLD) in which immune alteration is common. Recent studies suggested that certain platelets and lymphocytes activation markers may have an impact on progression of CLD. This study aimed to evaluate the potential of platelets and lymphocytes activation molecules expression on the pathogenesis of ...

BACKGROUND Both Schistosoma mansoni and Schistosoma haematobium cause schistosomiasis in sub-Saharan Africa. We assessed the diagnostic value of selected Schistosoma antigens for the development of a multiplex serological immunoassay for sero-epidemiological surveillance. METHODOLOGY/PRINCIPAL FINDINGS Diagnostic ability of recombinant antigens from S. mansoni and S. haematobium was assessed ...

Schistosoma haematobium is presented as a cause of vesicovaginal fistula in a nulliparous adolescent. The possible role of S. haematobium in failure of fistula repair and the importance of screening and treatment in endemic areas prior to repair are discussed.

Protective factors associated with atopy or asthma in rural areas include socioeconomic level, overcrowding, and helminth infection. However, little epidemiological information was originated from schistosomiasis areas. This study aimed to investigate factors associated with asthma in a schistosomiasis endemic area. A questionnaire was used to obtain information on demographics, socioeconomic, ...

This study aims to present an update on schistosomiasis mansoni. Schistosomiasis is a parasitic disease caused by trematode flatworms of the genus Schistosoma. S. mansoni is the only species of importance in the American continent. This disease is considered a serious public health problem in some countries. It is found in 72 countries and is endemic in at least 52 of them. Its pathogenesis dep...

The incidences of schistosomiasis and multiple sclerosis (MS) are mutually exclusive worldwide suggesting that schistosomiasis may offer protection against the induction of the immune-mediated disease, MS. Recent studies using the mouse model of MS, experimental autoimmune encephalomyelitis, support a direct suppression of the onset of MS by chronic Schistosoma mansoni infection. Self-reactive ...

We present a method for the examination of antiidiotypic cellmediated reactivity during chronic human infections. Pooled and individual sera from patients with schistosomiasis. mansoni were purified on immunoaffinity columns of schistosomal egg antigens (SEA). The eluates contained anti-SEA antibodies, but not SEA. These antibody preparations, and their F(ab')2 fragments, stimulated dose-depend...

Schistosomiasis, or bilharziasis, results from infection by one of several species of parasitic flukes of the genus Schistosoma. The World Health Organization describes schistosomiasis as a millenary disease, affecting over 200 million individuals living in 76 different countries across Asia, Africa, and the Americas. It is considered the most important helminthic human disease and constitutes ...

C57Bl/10 male mice infected with Schistosoma mansoni were distributed into mixed, prophylactic and curative groups. A culture of Zymomonas mobilis was orally administered to mice. A 61% protection from the infection was observed in the curative group (p <0.05). Histopathological study of the livers and intestines showed similar results.

The objective of this study was to evaluate the role of cytokines in hepatic fibrosis in the prehepatosplenic and early hepatosplenic stages of schistosomiasis mansoni. Hepatic fibrosis was classified by ultrasonography of 94 patients. Immunological evaluation was performed by the measurement of secreted cytokines (interleukin-5 [IL-5], IL-10, IL-13, gamma interferon, tumor necrosis factor alph...
