In 2002, human T-cell leukemia virus type 1 (HTLV-1) and HTLV-2 seroprevalence was 0.16% (8/4,900) in blood donors from Dakar,
Senegal. Most of the positive donors originated from the country’s southern region. Seven donors were infected by HTLV-1 (of
cosmopolitan subtype), and one was infected by HTLV-2. These data highlight the problem of transfusion safety in this area
where HTLV-1-associated lymphoproliferative and neurological diseases are endemic.

    ABSTRACT: The pseudo-Wigner distribution (PWD) is a time-frequency signal representation particularly suited for analyzing and processing `long' signals. Signal processing by means of PWD involves a signal synthesis step. Two signal synthesis algorithms for PWD are presented. These are the pseudopower method which allows optimal signal synthesis, but is computationally expensive for longer signals, and the partial sum method, which is suboptimal but suited for the synthesis of signals with arbitrary length. The performance of the two algorithms is demonstrated by simple synthesis experiments

    ABSTRACT: Melanesia is endemic for human T lymphotropic virus type 1 (HTLV-1) subtype C. In 2005, we identified 4 infected women from Ambae Island, Vanuatu. Subsequently, 4247 Ni-Vanuatu originating from 18 islands were enrolled to define HTLV-1 epidemiological determinants and to characterize the viral strains molecularly. Plasma from 1074 males and 3173 females were screened for HTLV-1/2 antibodies by particle agglutination (PA) and an immunofluorescence assay (IFA). Positive and/or borderline samples were then tested by a Western blot (WB) confirmatory assay. DNAs were amplified to obtain a 522-bp env gene fragment. Phylogenetic and molecular-clock analyses were performed. Of 4247 samples, 762 were positive and/or borderline by IFA/PA, and 26 of them were confirmed to be HTLV-1 positive by WB. The overall HTLV-1 seroprevalence was 0.62%. Viral transmission was found within families of infected index case patients. A geographic heterogeneity of HTLV-1 seroprevalence was observed among the islands. All 41 of the new env sequences belonged to HTLV-1 subtype C. Phylogenetic and molecular-clock analyses suggested that Ni-Vanuatu and Solomon Islander strains emerged from a common ancestor ~10,000 years ago. The Vanuatu archipelago is endemic for HTLV-1 with a diversity of subtype C variants. These strains were probably introduced into Vanuatu during ancient migration of the original settlers a few thousand years ago.

    ABSTRACT: Mycosis fungoides (MF) and Sezary syndrome (SS) are forms of primary cutaneous T-cell lymphoma. They are relatively rare diseases, infrequent in Europe, Asia, and Africa. In Rwanda, they remain very rare. Their etiopathogenesis has long been obscure and poorly understood. Recent studies, however, have confirmed that they are of viral origin, specifically human T-cell lymphotropic virus type I (HTLV-I) and human immunodeficiency virus (HIV). Their incidence is low: about three new cases per year per million inhabitants. Individuals affected are usually aged between 40 and 60 years and of male gender. The incidence of SS is less than one new case per year per million inhabitants. A new case of MF/SS syndrome against a HIV-positive background is described and a literature review is performed. Clinically, MF is characterized at onset by pruriginous, disseminated, erythematous, scaly plaques, localized on the skin, which gradually become infiltrative. In advanced stages, the nodular lesions can become ulcerated and Sezary cells are detected in the peripheral blood. Our male Rwandan MF/SS/HIV-positive patient presented with pruriginous, erythematous, scaly lesions, which had developed over 4 years and were now infiltrative, together with nodular lesions of various sizes, localized on the face, scalp, and palmar and plantar regions. All of these clinical signs, the anatomopathologic examination, retroviral serology, and testing of peripheral blood confirmed the diagnosis of MF/SS against a background of immunodepression. MF and SS are relatively rare cutaneous lymphomas, but have been diagnosed in Rwanda against a clinical picture of immunodepression. Their etiology seems to be viral in origin. MF and SS are difficult diseases to diagnose, with confirmation only at advanced stages. No tests exist to aid and confirm the diagnosis in the initial stages of the diseases. Further studies are urgently needed on these diseases.
