Human T-cell lymphotropic virus type 1 infection and ocular manifestations in Sao Paulo, Brazil.
Although human T-cell lymphotropic virus type 1 (HTLV-1) - associated uveitis has been well recognized in Japan, related studies in Brazil are scarce.
We performed a serologic survey for HTLV-infection among patients with uveitis and investigated the ocular findings in HTLV-1-asymptomatic carriers.
One hundred ninety serum samples from patients with uveitis of determined (n=137) and undetermined origins (n=53) being examined at the Uveitis Service, University of Sao Paulo, Sao Paulo, Brazil, underwent testing using HTLV enzyme-linked immunosorbent assay and discriminatory Western blots.
One hundred five asymptomatic blood donors and/or their relatives who were seropositive for HTLV-1 (carrier group) and 105 age-and sex-paired blood donors who were seronegative for HTLV-1 (control group) underwent ocular evaluation.
For the statistical analysis, X2 test was used.
Only 1 patient with uveitis was seropositive for HTLV-1, and she belonged to the group with uveitis of undetermined origin.
Results of tear films were evaluated in 52 carriers.
The prevalence ofa decreased tear break-up time was significantly higher in the carrier compared with the control group (P=02).
Two carriers had keratoconjunctivitis sicca.
Three of the 105 carriers exhibited mild uveitis (cells in the vitreous, retinal and choroidal infiltrates, retinal vasculitis, and bilateral pars planitis). (...)
