12 Ocular manifestations in HTLV-1 patients and its correlation with proviral load André Luiz Land Curi 1 , Eliezer Benchimol 1, Marcus Tulius T Silva 2, Ana Claudia Leite 2, Marco Antonio Lima 2 ,Abelardo Araujo 2, Maria Jose Andrada-Serpa 3

13 The median HTLV-1 proviral load was of 11,89 copies/100 leukocytes in patients with ocular changes (ranging from 2,93 to 22,34), significantly higher than in patients without ophthalmic abnormalities (median 4,79, ranging from 0,00 to 24,24; p < 0,0001 – Mann-Whitney test)

14 Five out of 44 individuals without HAM/TSP presented some ocular changes. The proviral load in this group was statistically higher than in patients without HAM and with normal ophthalmologic examination ( p = 0,002 / Mann Whitney test). Proviral load varied from 5,43 to 21,18 ( mean: 13,86) in the group with ocular changes and from 0,00 to 24,24 (mean : 3,84) in the group without ocular changes

15 Out of 81 patients thirty-three were AC
Out of 81 patients thirty-three were AC. In 3 of these some ophthalmic abnormality was detected.The median proviral load in these patients was 13,45 copies/100 leukocytes (ranging from 5,43 to 21,18). In AC without ocular changes (N 50) the median load was significantly lower (3,52 copies/100 leukocytes, ranging from 0,00 to 24,24; p = 0,017 – Mann Whitney test)

18 Conclusion : Corneal abnormalities were the most frequent ocular changes in patients with HTLV-1 infection in this Brazilian cohort study. As in neurologic diseases associated with HTLV-1 infection, proviral load was shown to be a good marker for the presence of ocular changes.
