Effects of single-dose praziquantel on morbidity and mortality resulting from intestinal schistosomiasis
AbstractThe long-term effect of single-dose praziquantel on morbidity and mortality from Schistosoma mansoni was investigated in surveys in 1987 and 1994 in central Sudan. Prevalence of infection dropped from 53% to 34%, and intensity of infection [400 eggs/g of faeces] from 31% to 18%. There was a reduction in hepatomegaly and hepatosplenomegaly, although splenomegaly alone was unchanged. Prevalence of periportal fibrosis decreased from 14% to 10%. Endoscopic investigation of patients with fibrosis showed a reduction in oesophageal varices from 47% to 30%. Mortality due to bleeding varices was high [community-wide, up to 11/100 infected patients with bleeding]. Thus praziquantel mass treatment can be spaced to a much longer period, reducing the expense of treatment, delivery and distribution

(2014)Schistosomiasis ranks second to malaria in terms of socioeconomic and public health importance in Yemen.This study assessed the validity of a morbidity questionnaire and urine reagent strips as a rapid tool for screening schoolchildren for urinary schistosomiasis as compared with the presence of eggs in urine as the gold-standard parasitological diagnosis.The study examined urine samples and interviewed 696 children [mean age 12.5 years]attending a primary-preparatory school in south Yemen.Urinary schistosomiasis was confirmed in 126 [18.1%]chi ...
