relationships of schistosoma haematobium, hookworm and malarial infections and metrifonate treatment to growth of kenyan school children.relationships of s. haematobium, hookworm and malarial infections to growth 6 months after metrifonate treatment were studied in kenyan primary school children in an area where poor growth, s. haematobium and hookworm were common and malaria was endemic. all children with light-moderate s. haematobium infections (1-500 eggs/10 ml adj) in 4 schools were examined (exam 1), allocated at random to either placebo (mip, n = 198) or metrifonate treatment (mit, n = 201) groups, treated, and examined aga ...19853938925
effect of praziquantel on hematuria and proteinuria in urinary five settlements on lake volta, ghana, 230 persons infected with s. haematobium were treated with either 30 or 40 mg/kg of praziquantel. both treatment regimes gave similar overall cure rates (60%) and reduction in geometric mean egg counts (92%) at a six-month follow-up. in this highly endemic area, 32% of the initial urine specimens were visibly bloody and only 4% remained bloody after treatment. geometric mean egg counts of visibly bloody urine specimens were two to six times higher than n ...19853938926
praziquantel for treatment of schistosomiasis in patients with advanced hepatosplenomegaly.we evaluated praziquantel for therapy of active schistosoma mansoni infection in 15 rural egyptian males with hepatosplenic schistosomiasis. criteria for inclusion in this study were two pre-treatment s. mansoni egg counts with a mean of greater than 100 eggs g-1 faeces and an enlarged spleen. fourteen of 15 patients had hepatomegaly, five had ascites, and six had serum albumin below 3 g dl-1. schistosoma haematobium infection (less than 10 eggs ml-1 urine) was present in three patients. praziqu ...19853938936
swamp rice farming: possible effects on endemicity of schistosomiasis mansoni and haematobia in a population in obtain a better understanding of the possible influence of swamp rice farming on the patterns of schistosoma mansoni and schistosoma haematobium infections, the populations of two communities in rural liberia were studied. in one village, balama (population of 435), swamp rice farms were initiated six years before the survey; in the other nearby community, gbarta (population of 216), swamp rice farms had not yet been initiated. the prevalence of s. mansoni infection in balama was 87% vs. 9% i ...19853970302
regression of splenomegaly and hepatomegaly in children treated for schistosoma haematobium infection.during a study in kenya of the relationships between schistosoma haematobium infection and anemia and growth, evidence was found to suggest that this infection was associated with splenomegaly in children, and that both splenomegaly and hepatomegaly regressed in children treated for urinary schistosomiasis, compared with a placebo group. these results imply that s. haematobium is partially responsible for the splenomegaly and hepatomegaly found in this malarious area, and that treatment for s. h ...19853970303
