Title: No evidence of HTLV-I infection in patients with mycosis fungoides and Sezary syndrome

Abstract: The involvement of human T-cell lymphotropic virus type I (HTLV-I) in the etiology of cutaneous T-cell lymphomas (CTCL) is still controversial. The aim of the study was to evaluate the role of HTLV-I in the pathogenesis of mycosis fungoides (MF) and Sezary syndrome (SS) in Polish patients. The studied group consisted of 42 patients with MF, 5 with SS and 25 with chronic dermatitis. DNA was extracted from snap-frozen and paraffin-embedded skin biopsies and from peripheral blood. Polymerase chain reaction (PCR or nested PCR) was carried out for amplification of different regions of HTLV-I genome. Primer sets flanking pX, p 19, U5, tax and pol genes were used in the investigation. The presence of HTLV-I antibody was examined in 46 sera samples with the use of anti-HTLV-I/II EIA test. HTLV-I antibodies were not detected in any collected sera samples. PCR with two primer sets homologous to the pX region of HTLV-I showed negative results in all samples investigated. To confirm these results two other primer pairs specific for U5 and gag regions were designed. With these primer pairs no PCR product, except that in positive control, was observed. For more sensitive amplification a nested-PCR with pol and tax specific primers was performed. HTLV-I probably does not play an important role in the pathogenesis of MF in Polish patients.
