[SHTLV-I/II seroprevalence in blood donors of Hospital Pablo Tobón Uribe Blood Bank during the period 2014-2015].

INTRODUCTION

The human-T cell lymphotropic virus is a retrovirus with various types known so far. HTLV-I and HTLV-II are of clinically importance as they cause different diseases such as adult T-cell leukemia/lymphoma, tropical spastic paraparesis, and human T-lymphotropic virus type I-associated myelopathy (HAM).

OBJECTIVE

To estimate the prevalence of presumptive and confirmatory reactivity to HTLV-I/II in blood donors of Hospital Pablo Tobón Uribe Blood Bank between 2014 and 2015.

MATERIALS AND

METHODS

The information was obtained from the Hospital Pablo Tobón Uribe Blood Bank database. We analyzed age, sex, place of origin, and place of residence of donors, and the reactivity using the screening test (ELISA) as well as the confirmatory test (immunoblot).

RESULTS

The donor population studied included 6,275 men and 8,148 women, for a total of 14,423 donors recruited between March 1, 2014, and June 30, 2015. Of all tested donors, 25 were positive for HTLV-I/II by the screening test (ELISA). After performing the confirmatory test (immunoblot), only nine patients were positive for HTLV-I/II (36%), of whom eight were reactive to HTLV-I (32%) and one to HTLV-II (4%), for a global seroprevalence of 0.06% (CI 95%: 0.10-0.25).

CONCLUSIONS

Our findings were consistent with those found in similar studies in non-endemic areas of the country and with those from studies at international level reported in the literature.
