چکیده
Immunoglobulins 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 less than 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 for IgM-MBP. The CSF analysis of patients with GBS showed that 56.3% revealed IgG-MBP (p less than 0.05), 53% for IgM-MBP, 38.5% 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 less than 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 antiphospholipid 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.

Spinal MRI findings of guillain-barré syndrome.
Guillain-Barré syndrome is a relatively common, acute, and rapidly progressive, inflammatory demyelinating polyneuropathy. The diagnosis is usually established on the basis of symptoms and signs, aided by cerebrospinal fluid findings and electrophysiologic criteria. Previously, radiologic examinations have been used only to rule out other spinal abnormalities. We report a case of systemic lupus...
متن کاملAnticardiolipin Antibodies in Juvenile Rheumatoid Arthritis and Systemic Lupus Erythematosus
Background: Antiphospholipid antibody syndrome (APS) can either occur as a primary syndrome or associated with other autoimmune diseases such as systemic lupus erythematosus (SLE). Anticardiolipin antibody (aCL) of IgG and/or IgM isotype in blood, measured by a standardized ELISA is the most acceptable laboratory criteria. APS IgG isotype, particularly IgG2 subclass is more strongly associated ...

Background: Libman-Sacks endocarditis (LSE) is characterized by sterile lesions that commonly affect the aortic and mitral heart valves. Antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE) have been associated with LSE. Cardiac manifestations including LSE could be interrelated with other manifestations and early diagnosis could help in preventing further complications. Case...
