Id: 17589 Author: Barreto, Jaison Antonio Title: Hanseniase dimorfa reacional: estudo comparativo, em biopsias cutaneas, entre reacao tipo 1 ocorridas antes e durante a poliquimioterapia ?- Source: Sao Paulo; s.n; 2005. [107] p. ilus, tab. Thesis: Present for Sao Paulo (Estado). Secretaria de Estado da Saude. Coordenadoria de Controle de Doencas presented for the degree Mestre. Abstract: A hanseniase dimorfa e a forma clinica mais frequentemente associada a ocorrencia de reaçoes de hipersensibilidade medida por celulas (reacao tipo 1), que podem ocorrer antes, durante ou depois do tratamento especifico. Ha varias teorias a respeito da patogenese dessas reacoes, as quais estao diretamente ligadas ao dano neural e as sequelas. Visando-se compreender melhor a fisiopatologia das reacoes tipo 1, foram estudadas 10 biopsias cutaneas de individuos com hanseniase dimorfa-tuberculoide reacional nao tratados e 10 de individuos dimorfos em reacao reversa (apos o inicio do tratamento especifico), comparando-se os parametros morfologicos e imunoistoquimicos. Observou-se no grupo em tratamento, maior positividade das celulas para a enzima oxida nitrico sintase induzivel (iNOS) e menor quantidade de linfocitos T CD8+(p menor 0,05). Nao houve diferenças significativas na baciloscopia e positividade para antigenos micobacterianos nos dois grupos, e nem na quantidade de celulas IL-10+, apesar de ter sido observada correlaçao negativa entre esta citocina e a proporçao CD4/CD8 nos pacientes em tratamento (p menor 0,05). Notou-se tambem, tendencia a reduçao do infiltrado especifico (linfocitos T e B) e aumento do numero de celulas citotoxicas inespecificas (NK) no grupo em tratamento. Estes resultados sao concordantes com trabalhos recentes, que surgerem que a reaçao tipo 1 representaria um desiquilibrio imunologico entre citocinas pro-inflamatorias e anti-inflamatorias...(AU).

Source: Hansen. int;29(2):141-144, Jul.-Dez. 2004. ilus. Abstract: Nesta secao, que neste numero se inicia, o periodico abordara temas relativos ao diagnostico e tratamento da hanseniase, com a participacao de varios especialistas convidados que procurarao transmitir de forma consensual as condutas mais pertinentes e atuais para o tema selecionado. Como primeiro assunto a ser abordado elegeu-se o "papel da biopsia cutanea no diagnostico de hanseniase", principalmente quanto as indicacoes, procedimentos, e interpretacao de alguns achados histopatologicos (AU).

Abstract: The immunohistochemical identification of neuropeptides (calcitonin gene-related peptide, vasoactive intestinal polypeptide, substance P, alpha-melanocyte stimulating hormone and gamma-melanocyte stimulating hormone) quantification of mast cells and their subsets (tryptase/chymase-immunoreactive mast cells = TCMC and tryptase-immunoreactive mast cells = TMC) were determined in biopsies of six patients with leprosy reactions (three patients with type I reaction and three with type II). Biopsies were compared with those taken from the same body site in the remission stage of the same patient. We found a relative increase of TMC in the inflammatory infiltrate of the reactional biopsies compared to the post-reactional biopsy. Also, the total number of mast cells and the TMC/TCMC ratio in the inflammatory infiltrate was significantly higher than in the intervening dermis of the biopsies of both periods. No significant difference was found regarding neuroptide expression in the reactional and post-reactional biopsies. The relative increase of TMC in the reactional infiltrates could implicate this mast cell subset in the reported increase of the immune response in leprosy reactions. (AU).

Nerve biopsies in three lepromatous and three dimorphous leprosy patients are reported. Bacilli were found in all three lepromatous nerves, and in one dimorphous nerve. Bacilli were present in cutaneous nerve twigs in all six patients. 2. Myelinated fiber counts were severly reduced in four patients. Large fibers were affected to a greater extent than small fibers. 3. Evidence of widespread segmental demyelination with remyelination was present. Wallerian degeneration was not found. 4. Schwann cell involvement with subsequent segmental demyelination appears to be an important event in the pathogenesis os leprous neuritis.(AU).
