 en Ultrasonography in Schistosomiasis in Africa
Ekkehard Doehring-Schwerdtfeger & Ruediger Kardorff

Abstract

Approximately 50 publications have become available in the
international literature on ultrasonography in schistosomiasis
in Africa. Geographically these cover Congo, Egypt, Kenya,
Mali, Mauritius, Niger, Senegal, Sudan, Tanzania and East
African Islands as well as  Zimbabwe. Further studies are
ongoing in many countries, such as Burundi, Ghana, Madagaskar
and Uganda.

It was shown that ultrasonography is useful in the detection of morbidity induced by schistosomiasis on an individual basis and on the community level. There is indication for varying morbidity patterns in different African foci. Post-treatment monitoring has provided evidence for reversibility of pathological lesions induced by Schistosoma (S.) haematobium and S. mansoni, even though evidence for reversibility of periportal fibrosis in adults is not yet satisfactorily substantiated. A standardized set of criteria for ultrasonographical observations has been worked out and is presently in the process of being refined. It is thus hoped that standardization will contribute to render studies in different endemic settings comparable on a global basis.
