[Circulating complexes of plasma fibronectin (fibronectin-fibrin) in human diseases].

The study of circulating complexes fibronectin-fibrin in 21 patients with immunocomplex affections revealed their high levels which occurred in inverse relationships with fibronectin concentrations in the blood, but in direct correlation with indicators of inflammation (fibrinogen, cialic acid). It is suggested that the complexes are involved in the development of fibrosis at the sites of chronic inflammation in immune disorders.
