MASSAU, Aline et al. The high prevalence of Torque teno virus DNA in blood donors and haemodialysis patients in southern Brazil. Mem. Inst. Oswaldo Cruz [online]. 2012, vol.107, n.5, pp. 684-686. ISSN 0074-0276. http://dx.doi.org/10.1590/S0074-02762012000500017.
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.
