Abstract
Background – Periportal fibrosis is the major pathological consequence of the Schistosoma mansoni infection. Objective – To evaluate the
accuracy of serum markers and to construct an index to assess fibrosis. Methods – Patients (n=116) with schistosomiasis were evaluated by ultrasound
scan and measurements of serum levels of aminotransferases, γ-glutamyl transferase, alkaline phosphatase, hyaluronic acid, cytokines and platelets.
Ultrasound images were used to evaluate the fibrosis using Niamey’s classification and identified 19 patients without periportal fibrosis (patterns A
and B), 48 with mild to moderate fibrosis (C and D) and 49 with advanced fibrosis (E and F). Results – Using multivariate analysis, a model was
created, which involved alkaline phosphatase and platelets and could separate patients with different patterns of fibrosis. This index showed a better
performance in separating patients without fibrosis from with advanced periportal fibrosis. The biological index showed an area under the ROC
curve of 1.000. Using values below the lowest or above the highest cut-off point, the presence or absence of advanced fibrosis could be predicted
in all patients. Conclusion – The index constructed can be used to separate patients with different patterns of periportal fibrosis, specially to predict
advanced fibrosis in schistosomiasis patients.
