There is no evident correlation between interleukin-10 gene polymorphisms and periportal fibrosis regression after specific treatment

Abstract INTRODUCTION: We evaluated the associations between interleukin-10 (IL-10) gene polymorphisms -G1082A/-C819T/-C592A and periportal fibrosis regression after specific treatment for schistosomiasis. METHODS: This retrospective cohort study involved 125 Brazilian patients infected with Schistosomiasis mansoni, who were followed up for 2 years after specific treatment to estimate the probability of periportal fibrosis regression. RESULTS: There was no evidence of associations between IL-10 polymorphisms and periportal fibrosis regression after treatment. CONCLUSIONS: There was no evidence of associations between gene promoter polymorphisms of IL-10 and the regression of periportal fibrosis in this Brazilian population.
