False-positive human T-lymphotropic virus serology after intravenous immunoglobulin transfusion.

Evaluating the Frequency of Human T-Lymphotropic Virus Type 1 Infection in Iranian Population

Background: Human T-cell lymphotropic viruses 1 (HTLV1) is endemic in specific regions. We aimed to determine the prevalence of HTLV I infection among blood donors in southeast Iran.   Methods: This cross-sectional study was conducted between April 2005 and March 2015. Sera were collected from blood donors and were tested for the presence of HTLV1 specific antibody using ELISA. Reactive sample...

Incidence of Human T-Lymphotropic Virus Type 1 (HTLV-1) among Blood Donors from Ilam, Iran

Transfusion-transmitted human T-cell lymphotropic virus type I infection in Taiwan: a true risk and occasional coinfection with hepatitis C virus shown in a prospective study.

To study the incidence of human T-cell lymphotropic virus (HTLV) after blood transfusion in Taiwan, serum samples from 699 patients in a prospective study were examined for seroreactivity of anti-HTLV. By an enzyme immunoassay, 9 of the 699 recipients were repeatedly positive. Serial serum samples of these 9 patients were then confirmed with a Western blot analysis and with a polymerase chain r...

Evaluation of surrogate markers for human immunodeficiency virus infection among blood donors at the blood bank of "Hospital Universitário Regional Norte do Paraná", Londrina, PR, Brazil.

This study evaluated the usefulness of the anti-HBc, hepatitis C virus antibodies (anti-HCV), human T cell lymphotropic virus I and II antibodies (anti-HTLV I/II), serologic tests for syphilis, and surface antigen of hepatitis B virus (HBsAg) as surrogate markers for the risk for HIV infection in 80,284 serum samples from blood donors from the Blood Bank of "Hospital Universitário Regional Nort...
