Abstracts
Immuneglobulins isotypes (IgG and IgM) for myelin basic protein (MBP), cerebrosides (CER), gangliosides (GANG) and cardiolipin (CARD) were detected in the cerebrospinal fluid (CSF) from 33 patients with multiple sclerosis (MS), 18 with Guillain-Barré syndrome (GBS) and 30 with systemic lupus erythematosus (SLE). In MS patients occurred positive and significant levels of IgG-MBP in 51,5% (p<0.05) and IgM-MBP in only 18.2%, IgG-CARD in 46.2%, as long as CER and GANG were detected in almost 20%. From serum samples of MS patients 20.6% presented IgG-MBP, while 53% showed positive levels foi IgM-MBP. The CSF analysis of patients with GBS showed that 56.3% revealed IgG-MBP (p<0.05), 53% for IgM-MBP. 3&.5% for IgG-CER and 23% for IgM-CER, while 50% of patients had IgG-CARD, as long -as 31% also had IgG-GANG. The serum evaluation from 14 patients showed that 18.8% had positive concentrations of IgG-MBP and 56.3% presented IgM-MBP (p<0.05) Except for 50% of patients with SLE who presented positive CSF levels of IgG-CARD. only 24.1% had positive levels of IgG-MBP. We believe that the presence of antiphosphohoid antibodies in CSF of the above mentioned diseases occurred as immune epiphenomena, but their appearance would permit the maintenance of and perpetuate the immune event.
Isotipos de imunoglobulinas (IgG e IgM) de proteína básica de mielina (PBM), cerebrosídeos (CER), gangliosídeos (GANG) e cardiolipina (CARD) foram investigados em amostras de liqüido cefalorraquidiano (LCR) de 33 pacientes com esclerose múltipla (EM), 18 com síndrome de Guillain-Barré (SGB), e 30 com lúpus eritematoso sistêmico (LES). Pacientes com EM revelaram concentrações positivas e significantes para IgG-PBM em 51,5% (p<0,05), IgM-PBM em 18,2%, IgG-CARD em 46,2%; CER e GANG foram detectados em cerca de 20% dos pacientes. A avaliação dos isotipos de imunoglobulinas no soro de pacientes com EM foi positiva em 20,6% para IgG-PBM e. 53,0% para IgM-PBM. No LCR dos pacientes com SGB a análise mostrou-se positiva em 56,3% para IgG-PBM (p<0,05), 53% para IgM-PBM, 38,5% para IgG-CER e 23% para IgM-CER, 50% para IgG-CARD e 31% para IgM-GANG. Os isotipos avaliados no soro de 14 pacientes com SGB foram positivos em 18,8% para IgG-PBM e 56,3% para IgM-PBM (p<0,05). No LCR, 50% dos pacientes com LES revelaram positividade para IgG-CARD e 241% para IgG-PBM. Os autores acreditam que a presença de anticorpos antifosfolipides seja conseqüente a epifenômeno imune, embora sua presença possa manter e perpetuar o evento imune intrínseco a essas doenças.
