Resumen
This study investigates the frequency of Torque teno virus (TTV) infection in 150 blood donors and 77 patients
requiring haemodialysis in southern Brazil. Plasma samples were screened for TTV DNA using polymerase chain
reaction (PCR). The prevalences of TTV among blood donors and patients requiring haemodialysis were 73.3% and
68.8%, respectively. The presence of TTV was correlated with age in the blood donors (p = 0.024). In haemodialysis
patients, no association was found between TTV infection and the demographic parameters (age, sex and education),
the duration of haemodialysis or a history of blood transfusion. This study is the first to evaluate the prevalence of
TTV infection in Brazilian patients requiring haemodialysis.
