Background. The aim of this study has been to evaluate the prevalence of APC-resistance phenotype in a community of the upper Aniene Valley, geographic area of eastern Lazio region, Italy.
Methods. The Activated protein C (APC)-resistance phenotype was searched in 183 women aged <40, included between 305 consecutive asymptomatic outpatient subjects, all resident in the upper Aniene Valley, examined during for a coagulative screening for inherited thrombophilia. The assessment of APC-r was carried out using a commercially available plasma-based method (FV aPTT method).
Results. The APC-resistance phenotype was found in five of the 183 young women (2.73%) and in ten of the 305 overall subjects (3.27%).
Conclusions. These percentages of prevalence are in agreement with the distribution of the Leiden mutation in the Italian general population and confirm a large diffusion of this defect also in our community.
