Abstract:
Objective To observe the uhrasenographical characters of liver and spleen of residents and their changes in endearic areas of schistosomiasis japonica in Poyang Lake region.Jiangxi Province and to explore the value of ultrasonography for assessment of the morbidity of the disease.Methods All permanent residents aged above 3 years old were examined by ultrasonography and Kato-Katz method.Results The schistosome positive rates of fecal examinations decreased obviously from 16.29%in 1995 to 8.54%in 2007(P<0.01).However,the rates of hepatomegaly and splenomegaly between 1995 and 2007 were not significantly changed(P>0.05),with the rates of 8.82% and 20.33% in 1995 and 8.54% and 21.34% in 2007,respectively.The abnormal rate of portal vein diameter decreased significantly.from 32.47%in 1995 to 6.50% in 2007.The abnormal rate of liver parenehyma increased remarkably(P<0.01),from 34.85% to 51.83%.The changes of liver parenchyma Grade I showed a bidirectional trend,29.90% of them chased into Grade 0(normal image on ultrasonngraphy),and 34.02% changed into Grade 2 and above.The abnormality of various indices of uhrasonography examinations were related to age,occupation and schistesome infection status.Conclusions Ultrasonography can show the damages of liver and spleen of patients infected with Schistosoma japonicum directly.but it is necessary to study further on the sensitive indices that reflecting early pathological changes and the best combination of the indices for the assessment of schistosomiasis-related morbidity.
