  • Title: Haemorheological profile in patients with systemic sclerosis.
    Author: Vayá A, Todolí J, Calvo J, Romagnoli M, Ricart JM.
    Journal: Clin Hemorheol Microcirc; 2008; 40(3):243-8. PubMed ID: 19029648.
    Abstract:
    The relationship between rheological alterations and systemic sclerosis (SSc) is not well established. We have determined in 27 patients with SSc (4 male, 21 female ) aged 59 +/- 14 years and in a well matched control group the whole rheological profile, i.e. blood viscosity (BV), plasma viscosity (PV), erythrocyte aggregation (EA), erythrocyte deformability (ED) along with fibrinogen (Fbg), C-reactive protein (CRP), lipids, and erythrocyte indices. Patients show higher Fbg, PV and EA (P<0.01) and lower ED (P<0.01). A negative significant correlation was found between ED and inflammation markers, both CRP (P<0.05) and Fbg (P<0.01), indicating that decreased ED seems to be related to inflammatory changes at microcirculatory levels. In addition, patients with anticentromere antibodies show significantly lower ED than those without (P<0.05). The clinical significance of this observation needs to be clarified, deserving further research.
