Histopatologia da leishmaniose tegumentar por Leishmania braziliensis braziliensis. 2. Resposta humoral tissular

Abstract: Os A.A. analisaram a resposta humoral nas lesões de 90 pacientes de Leishmaniose Tegumentar — causada por Leishmania braziliensis brasiliensis —, utilizando o método da imunoperoxidase para identificar nos tecidos a presença de IgA, IgG, IgM, fração C3 do complemento e fibrina. Constataram a presença de IgA, IgC e IgM nos plasmócitos tissulares, com predomínio de IgG. Admitiram aue a passagem dessas imunoglobulinas para os tecidos possibilitando a opsonização do parasites e/ou de seus antígenos, permitiria a o… Show more

“…Plasma cells were frequently observed in the infiltrates of tissue lesions in all of the groups and they were more common than B lymphocytes in the LCL and DL late ulcerative lesions; this observation is consistent with previous studies showing that most of these cells are mature at the lesion site and are responsible for immunoglobulin production in situ (Magalhães et al 1986, Esterre et al 1992, Vieira et al 2002). In contrast to CD4 + T lymphocytes, the recruitment of B lymphocytes and plasma cells did not occur gradually with disease progression in any clinical form.…”

“…CL is characterised by a single ulcer, which is also referred to as localised CL (LCL) and this ulcer may spontaneously regress or disseminate into the multiple ulcers and papules, which are characteristic of disseminated leishmaniasis (DL), an emerging form of leishmaniasis (Costa et al 1986, Turetz et al 2002). Multiple studies of the morphological pathology of leishmaniasis have been performed in attempts to establish a morphological pattern that could be used to differentiate between the lesions (Azulay 1960, Ridley et al 1980, Magalhães et al 1986a). …”
