The purpose of this ... Twenty-seven LV patients and 21 cutaneous small vessel vasculitis (CSVV) patients, all at the active stage, were included. Platelet parameters in active- and stable-stage LV and CSVV patients were com... LV patients' mean age was 25.48 years (range: 9-62 years), and 81.48% (22/27) were women and 18.52% (5/27) were men. The platelet counts and plateletcrit (PCT) levels were significantly elevated in LV... Altered platelet morphology was detected in LV patients. Platelet count and PCT might be haematological biomarkers for early prediction of LV activity and relapses and for differential identification ...
