Central nervous system (CNS) involvement in systemic lupus erythematosus (SLE) remains difficult to diagnose, particularly since structural abnormalities may not be revealed by magnetic resonance imaging (MRI). Glucose utilisation was measured by positron emission tomography (PET) in 35 SLE patients to detect signs of CNS involvement. The patients were(More)
We performed positron emission tomography (PET) using 18F-labeled 2-F-2-deoxyglucose in 13 patients with systemic lupus erythematosus (SLE). Ten of them had clinical signs of central nervous system involvement (NP-SLE). All patients with neurologic symptoms showed pathologic changes on PET, always in accordance with the clinical state. Three patients(More)
Using a C1q binding test, circulating immune complexes (IC) were detected in 33.3% of sera from 138 patients and in 19.4% of 124 spinal fluid samples from patients with multiple sclerosis. Most often they occur in sera alone. As a rule their detectable amount is small in sera as well as in spinal fluids. IC were observed with equal frequency during acute(More)
Positron emission tomography (PET) and magnetic resonance imaging (MRI) studies were performed on a case of neuro-Behçet's syndrome. In accordance with the clinical signs, FDG PET (using 18F-labeled 2-F-2'-desoxyglucose) revealed disseminated storage defects in the cerebrum and cerebellum. Focal regions of enhanced signal intensity were demonstrated in the(More)
To support the hypothesis of an immunopathogenesis of polyneuropathy in Waldenström's macroglobulinaemia (MW), serum IgM fractions of MW patients were applied intraperitoneally to mice for 17 days. Sections of liver, kidney, M. glutaeus maximus, central nervous system (CNS) and both Nn. ischiadici were examined for IgM, IgG, C3 and as control IgD with(More)
Sera of 23 patients with Waldenström's macroglobulinaemia and six monoclonal IgM paraproteins, which had been isolated from these sera, were examined for reactivity against peripheral nerve tissue. Of these 23 patients, 12 had clinical signs of peripheral polyneuropathy (PN). Using an indirect immunofluorescence method, all sera and monoclonal IgM(More)
