The role of alpha-1-antitrypsin in the etiopathogenesis of chronic venous disease: A prospective clinical trial.

We believe that our hypothesis that low AAT levels play a role in the etiopathogenesis of CVD has been partially validated, at least in the CEAP-4 group. However, we believe that increased AAT levels in the CEAP-5 group may be a reactive increase in increased LE levels due to higher CRP levels of this group.
