Abstract/OtherAbstract:
Summary.  The history behind the production of clotting factor concentrates produced differences in the prevalence of Hepatitis C Virus (HCV) and other blood-borne infections in haemophilic patients. Prevalence rates of HCV infection up to 100% were reported in patients treated with concentrates before 1985. Conversely, nowadays, viral inactivation and recombinant technologies have effectively prevented transfusion-transmitted viral pathogens. Recently, new HCV infections in three young brothers were observed. In the absence of any other risk of transmission, their HIV/HCV coinfected uncle, who was living in the same house, was subject to study. Plasma samples of the four relatives were investigated in order to test whether the infections have a common source. A phylogenetic approach using the most variable (E2) viral sequences was carried out using samples from the four family members. The HCV sequences from the study resulted highly related, being those obtained from the uncle the most ancestral ones. Because of the chronological order in which the infections occurred and the relatedness of the sequences, an infection from the uncle to his nephews is the most likely explanation. Special cares must be applied in the case of household contact among members of a family with inherited bleeding disorders.
