The lymphotropic virus of human T-cell I and II (HTLV-I/II) present genoma
of ribonucleic acid (RNA) and generally infect CD4+ cell, with endemic frequency in
some areas like Japan and Caribe with greater or minor predominancy in other places;
in Brasilian Amazonia, the research is mainly connected to the native population. These
virus are relationed with malign deseases, neurological disturbances and
il11unodeficiencies, which cause viremia for long time without clinical effects. The
HTLV is regarded as an ethiological agent of adult T-cell leukemia/lymphoma (L/LTA)
and tropical spastic paraparesis / HTLV-I associated myelopathy (PET/HAM) among.
This analisys has the mais purpose of researching the presence of HTLV and situate the
most frequent (HTLV-I/II) in children with Acute Lymphoblastic Leukemia treated in
the authorized Cancer Assistence in Belem, Para State, Brazil, observing the
transmition way by lactation, the neurological symptoms with infections and its
bibliografic revise. The rear search of virus was accomplish through the PCR
(Polimerase Chain Reaction) tecnique that shows differences among HTLV-I and
HTLV-II. Parameters among age, sex, skin lesions,
progression and blood transfusion by porcentage had been remarked in a little girl,
without relationship to transmition by breastfeeding, and there was no conection with
HTLV as na ethiological agent of lymphoidal cells of neoplasia in childhood.
