Análise imunocitoquímica do infiltrado inflamatório na miosite com corpos de inclusão citoplasmática e em outras doenças neuromusculares com vacúolos marginados

Abstract: RESUMO -Encontramos 16 casos com vacúolos marginados entre 1400 biópsias musculares cujo diagnóstico final foi miosite com corpos de inclusão citoplasmática esporádica (MCIC) (4 casos), atrofia muscular espinhal juvenil (6 casos), miopatias distais (3 casos), distrofia das cinturas pélvica e escapular (2 casos) e neuropatia periférica (1 caso). Foram utilizados anticorpos monoclonais contra linfócitos T totais e subpopulações (CD4+ e CD8+), linfócitos B, macrófagos, células exterminadoras naturais (NK), imunog… Show more

“…The inflammatory infiltrates consist of CD8+ T cells and macrophages, suggesting involvement of a T cell mediated cytotoxic mechanism against muscle fibres 10 . Although we could not perform techniques for amyloid, as specific antibodies against beta amyloid or immunocytochemical analysis and ultrastructure techniques, the morphological changes seen in our case, particularly the lymphocytic infiltration and the rimmed vacuoles, although non-specific, are highly suggestive of IBM.…”

“…Typical features of this myopathy are ragged red fibres and paracrystalline inclusions in mitochondria that have been attributed to its DNA (mtDNA) depletion 13 . Ragged red fibres may be seen in rare cases of IBM suggesting that mitochondrial function is impaired in this disease 10 .…”
