Abstract
Our previous study has for the first time demonstrated that atopic dermatitis (AD) patients show enhanced plasma concentrations of PF4 and beta-TG. In addition, it has been suggested that chemokines may be the markers of AD severity. The aim of this study was to determine whether enhanced platelet activation in active AD withdraws when the disease reaches the clinical remission stage. Plasma PF-4 and beta-TG concentrations were studied in 10 AD patients and in 23 healthy controls. Patients were examined twice: first, during the active period, and next, during the clinical remission lasting for at least 6 months. Plasma PF-4 and beta-TG concentrations in patients upon AD remission were significantly lower as compared to active AD and did not differ significantly from the healthy subjects. Enhanced platelet activation is a transient phenomenon accompanying active AD and disappears during clinical remission. As with earlier data, the findings point to platelet activity in AD increasing during flare, falling following therapy and normalizing upon remission.
