Serum concentration of N-terminal procollagen peptide of collagen type III in schistosomal liver fibrosis.

The major cause of mortality in human schistosomiasis is the chronic granulomatous reaction of the liver tissue to Schistosoma mansoni eggs. Liver biopsy still provides the best evaluation of the degree of liver damage. However, liver biopsy does not provide an image of the dynamic process of fibrogenesis. Variations of concentrations of procollagen type III peptide in sera have been proposed to be significant markers of liver fibrosis. Thus, liver function tests in relation to histopathological diagnosis and procollagen type III peptide concentrations were studied in patients with schistosomiasis and revealed a high correlation between the serum procollagen type III peptide and the degree of fibrosis in liver tissue.
