schistosomiasis

 [shis″-, skis″to-so-mi´ahsis]
infection with flukes of the genus Schistosoma; called also bilharziasis. The disease is rare in North America, but is a significant health problem in many parts of the world, including the Middle East, Africa, East Asia, South America, and the Caribbean. Different species cause different forms of the disease: S. mansoni and S. japonicum produce intestinal symptoms, while S. haematobium produces hematuria and other urinary symptoms. The early stages of acute infection with S. japonicum produce katayama fever, a serum sickness–like illness. Initial treatment includes correction of anemia and other nutritional disorders caused by the parasites; definitive treatment may be delayed until acute symptoms subside. Anthelmintic medications are administered, such as oxamniquine or praziquantel. Improvement in sanitation and snail control are the chief preventive measures.

schis·to·so·mi·a·sis

(shis', skis'tō-sō-mī'ă-sis),
Infection with a species of Schistosoma; manifestations of this often chronic and debilitating disease vary with the infecting species but depend in large measure on tissue reaction (granulation and fibrosis) to the eggs deposited in venules and in the hepatic portals, the latter resulting in portal hypertension and esophageal varices, as well as liver damage leading to cirrhosis. See: tropic diseases.

But, the high prevalence of HCV infection among contacts to HCV-negative patients could be explained by the past history of hospitalization, surgical procedures, exposure to used syringe, circumcision by nonmedical personnel, and prior injection treatment for Bilharziasis.
Moreover, it was found that HCV-positive contacts were more likely exposed to sources of infections such as shaving at common barber, infected blood, and Bilharziasis. Thus, the risk of HCV infection increased with environmental exposure to potential sources of infection.

Schistosomiasis (bilharziasis) has been a focus of various studies because of its medical, veterinary and social importance (Chitsulo et al., 2000; Ross et al., 2002; WHO, 2002; Ravindran et al., 2007; Abdel et al., 2008; Da,dara et al., 2008; Atupele et al., 2009; Hirofume & Hiroshi, 2009).

Unfortunately, in terms of identifying a new parasite, in 1902 Sir Patrick Manson had described in England a single case of intestinal bilharziasis from a patient from the Caribbean island of Antigua finding oval eggs with lateral spines.
These three species are the main vectors of various species of schistosomes, agents of bilharziasis in humans (Malek 1985; Brown 1994).
