The severity of the disease was estimated by an adopted clinical scoring system. Platelet count (PLT), mean platelet volume (MPV), plateletcrit (PCT), and platelet distribution width (PDW) indices at the time of diagnosis were recorded. </span> </div> <div style="text-align:justify;"> <span style="font-size:14px;">Results: Overall, 76 HSP patients (mean age: 7.4±2.5 years, 56.5% male) were evaluated. HSP was classified as mild in 59 (77.6%) cases and severe in 17 (22.4%). MPV was significantly lower in severe HSP patients (7.6±1 vs. 8.44±1.1, p<0.01), however, there was no significant difference for PCT and PDW parameters. Relapse occurred in 14 patients (18.4%, 5 mild HSP and 9 severe HSP patients) during follow up. Severe HSP cases were more prone to relapse (p<0.01) and relapsing HSP patients had lower PDW (13.2±3.1 vs. 14.8±2.4 p<0.05). </span> </div> <div style="text-align:justify;"> <span style="font-size:14px;">Conclusions: MPV level obtained at the time of first presentation of the HSP disease has a discriminative value for mild and severe HSP. Also, lower PDW might be predictive to suspect the HSP patients susceptive to relapse. </span> </div>}, number={2}, publisher={Oğuz KARABAY}, organization={Yok}
