Evolution of schistosomiasis-induced pathology after therapy and interruption of exposure to schistosomes: a review of ultrasonographic studies

Schistosomiasis mansoni in low transmission areas: abdominal ultrasound

“…Moreover, using this classification it is difficult to establish the differences between periportal thickening grades 0 and I. In consequence, for the diagnosis of early pathology the sensitivity and specificity are lower (Boisier et al 1995, Nooman et al 1995, Thomas et al 1997, Richter 2000. However, these precocious lesions are the most important to be identified because are more prevalent among the population living in endemic areas.…”

Serum hyaluronan and collagen IV as non-invasive markers of liver fibrosis in patients from an endemic area for schistosomiasis mansoni: a field-based study in Brazil

“…Considered a simple, safe and low-cost method, after the advent of portable equipment, it has been of invaluable help in the screening of populations living in endemic areas and in field-based studies of the disease. Taken as a nearly ideal tool in the diagnosis and classification of schistosomiasis, it is now used as a surrogate for the gold-standard in the diagnosis of schistosomiasis-related liver fibrosis (Doehring-Schwerdtfeger et al 1989, Abdel-Wahab et al 1992, Richter et al 1992, Abdel-Wahab & Strickland 1993, pinto-Silva et al 1994, Richter 2000, Kariuki et al 2001, Cota et al 2006, Marinho et al 2006, Ruiz-Guevara et al 2007.…”

Liver morbidity due to Schistosoma mekongi in Cambodia after seven rounds of mass drug administration

“…It was concluded that pathological changes around the portal tree might regress to a large degree but that 'network pattern' abnormalities do not normally resolve (Richter, 2000). A comparable finding was obtained in a 2-year cohort study in Stung Treng province in Cambodia for S. mekongi between 1997 and 1999 (Hatz, 2001).…”
