Seroprevalencia de tamizaje frente a virus linfotrópico de células T (HTLV) y factores asociados a coinfección en donantes voluntarios de sangre de Colombia

Abstract

Objective: To determine the seroprevalence of HTLV screening and factors associated with co-infection in blood donors in Colombia. Materials and Methods: We performed a retrospective cross-sectional study inferential, the population was of 971 records of volunteer blood donors, we calculated prevalence of HTLV and calculated odds ratios (OR). Results: 49.3 % of donors were between 18 and 33 years, 53.4 % were female, 44.3 % lived with a partner, it was observed that the major syphilis coinfections are 7.0 %. There is a trend to increased prevalence of HTLV between 2010 (0.23 %) and 2011 (0.24 %) in the process of Bogota. Headquarters in related factors associated, positive association was found with increasing age and living with partner, and negative association with contributory system in multiple Poisson regression showed that the prevalence of co-infection is 2.92 (95 % CI 1.92 to 4.45) times in people 34 to 64 years compared to under 34 years, also the contributory scheme protects coinfection 0.69 (95 % CI 0.48-0.99) in people with contributory scheme compared to the subsidized regime. Conclusion: In general there is a significant proportion of donors with reactive results are set out clearly and factors associated with coinfection prevalence is higher than in other reports.
