ABSTRACT A 24-year-old Japanese woman was admitted to our hospital in 1987 with a chief complaint of skin eruptions, and was diagnosed as having chronic ATLL. In 1993 the leucocyte count increased gradually to 126.0 x 10(9)/l with 91.5% abnormal lymphocytes expressing two different types of antigenicity, either CD+/CD8- or CD4-/CD8+. Monoclonal integration of human T-cell lymphotropic virus type-I proviral DNA was detected at different sites of the genomic DNA in each cell type. These studies clearly indicate that CD4+/CD8- and CD4-/CD8+ leukaemic cells originated from two independent clones.

    ABSTRACT: In this review, we discuss the possible relationship between the clinical characteristics and the multiple integration of human T-cell lymphotropic virus type I (HTLV-I) proviral DNA in patients with adult T-cell leukemia/lymphoma (ATL). Some patients with ATL show multiple HTLV-I integrations and exhibit clinical characteristics unlike those of ATL patients who show the typical integration of a single provirus. Multiple HTLV-I integrations can be detected by Southern blotting as multiple bands having varied intensities. These multiple integration conditions can arise from one tumor cell clone carrying multiple copies of the provirus, or from multiple cell clones, each carrying one copy of the provirus. The former patients manifest an extremely aggressive clinical course with the infiltration of unusual organs such as the retina and uvea. The latter patients show an indolent clinical course with skin lesions. These findings suggest that the clinical implications for multiple HTLV-I integrations exist in ATL. This may be one of the explanations for the heterogeneous findings in the disease. Such observations may provide information linking viral integration with clinical manifestations, and improve our understanding of the pathogenesis of ATL.

    ABSTRACT: We report a case of Sezary syndrome with two abnormal CD4+ T-cell populations detected in the peripheral blood by flow cytometry immunophenotyping and DNA cell content, suggesting a biclonal T-cell lymphoproliferative disorder. Despite these findings, molecular analysis of the T-cell receptor genes was consistent with a monoclonal T-cell proliferation, supporting the existence of intraclonal diversity rather than a true biclonal disease. The patient achieved a transient response with 2-deoxycoformycin, with a selective decrease of the larger/hyperploid T-cell population; later on, an increased representation of this T-cell population was observed concomitantly with clinical relapse.

    ABSTRACT: The association of CD26/dipeptidyl peptidase IV (DPPIV) and human T lymphotropic virus type I (HTLV-I) was studied by two approaches. First, we examined the expression of CD26 in peripheral blood mononuclear cells (PBMC) from the patients with adult T cell leukemia/lymphoma (ATLL), an HTLV-I-related malignancy. The expression of CD26 on the surface of PBMC was decreased in all 20 patients with ATLL compared with those from normal individuals (P < 0.01) and the expression of the CD26 gene transcript was not detectable in seven out of eight patients with ATLL. Then we compared the quantity of viral DNA in CD26-negative (CD26-) and CD26-positive (CD26+) cells obtained from 17 HTLV-I healthy carries by using a polymerase chain reaction method. The CD26-cells had a higher copy number of viral DNA than CD26+ cells. These findings indicate that HTLV-I has in vivo tropism to CD26- cells, suggesting that some phenotypes of ATLL cells reflect the in vivo cellular tropism of HTLV-I.
