Behçet's disease patients with multiple sclerosis-like features: discriminative value of Barkhof criteria.

Objectives: Behçet's disease (BD) is a systemic auto-inflammatory disorder of unknown cause, which may affect the central nervous system in around 5% of the patients [neuro-BD (NBD)], usually causing large lesions encompassing brainstem, diencephalon and basal ganglia regions. Occasionally NBD patients present with white matter lesions necessitating differential diagnosis from multiple sclerosis (MS). In this study, the efficacy of Barkhof criteria was tested in diagnostic differentiation of NBD and MS.

Intrathecal oligoclonal IgG bands are infrequently found in neuro-Behçet's disease.

Objectives: Oligoclonal bands (OCB) of immunoglobulins (IgG) in the cerebrospinal fluid (CSF) provides an evidence for the humoral response and have been screened in the CSF and serum of patients revealing 5 different patterns. In this study, patients with Behçet's disease (BD) are screened in a larger sample to potentially provide information about the possible role of CSF oligoclonal immunoglobulins in the diagnosis of this disease.

Methods: Paired CSF and serum samples from 121 consecutive BD patients with neurological complaints (43 women and 78 men) were included in this study.

Cognitive impairment in neuro-Behcet's disease and multiple sclerosis: a comparative study.

Both multiple sclerosis (MS) and neuro-Behcet's disease (NBD) can cause a cognitive dysfunction mainly involving the executive functions. We conducted this study to clarify the probable differential cognitive/behavioral profiles of MS and NBD. Twenty consecutive cases with parenchymal NBD (13 male, seven female), and 20 cases with MS (five male, 15 female) were evaluated.

Association of amyotrophic lateral sclerosis and Behcet's disease: is there a relationship? A multi-national case series.

Neurological involvement may be seen in 5-30% of the patients with Behcet's disease (BD). Occasionally, parenchymal neurological involvement in BD can present as a spinal cord syndrome. However, motor neuron disease-like presentation is extremely uncommon.

Mycophenolate mofetil as a novel immunosuppressant in the treatment of neuro-Behçet's disease with parenchymal involvement: presentation of four cases.

Objectives: Behçet's disease is a multisystemic, relapsing, inflammatory disorder of unknown origin. Among Turkish cohorts, 5-15% of patients show involvement of the central nervous system (CNS) at some time during their disease. There are mainly two types of clinical presentation: parenchymal CNS inflammation manifesting mainly as meningoencephalitis of the brainstem, or dural sinus thrombosis.

The comparison of socio-economic conditions and personal hygiene habits of neuro-Behçet's disease and multiple sclerosis patients.

The "hygiene hypothesis" suggests that a reduction in the exposure to infectious agents due to improved health conditions has contributed to the increased incidence of autoimmune disorders in developed countries. In keeping with the hygiene hypothesis, many autoimmune disorders such as multiple sclerosis (MS) are more frequently observed in developed countries. To identify the relevance of hygiene hypothesis in neuro-Behçet's disease (NBD), another chronic inflammatory disease of the central nervous system, we developed and administered a multiple choice questionnaire to evaluate the hygiene conditions and practices of age and gender-matched NBD patients (n = 50) and control MS (n =5 0) and headache (n = 50) patients.

Prognostic implications of aquaporin-4 antibody status in neuromyelitis optica patients.

Neuromyelitis optica (NMO) is an inflammatory/demyelinating disorder predominantly affecting the optic nerves and spinal cord. Recent findings showed an underlying humoral abnormality in NMO, characterized by a serum antibody against aquaporin-4 (Aqp-4-Ab). In this study, we evaluated the Aqp-4-Ab status among Turkish patients with NMO to determine the clinical and prognostic relevance.

Enhanced IL-6 production in aquaporin-4 antibody positive neuromyelitis optica patients.

Anti-aquaporin-4 (Aqp-4) antibody and complement system have emerged as major pathogenic factors in neuromyelitis optica (NMO). To test the significance of interleukin-6 (IL-6), another important humoral immunity factor, in NMO pathogenesis, we measured serum and cerebrospinal fluid (CSF) IL-6 levels of 23 NMO, 11 transverse myelitis, 16 optic neuritis, 27 relapsing remitting multiple sclerosis patients, and 20 neurologically normal controls. NMO and transverse myelitis patients had higher serum and CSF IL-6 levels than other groups.

Interleukin-6 in neuro-Behçet's disease: association with disease subsets and long-term outcome.

Increased cerebrospinal fluid (CSF) IL-6 has been reported in patients with Behçet's disease (BD) and neurological involvement. To elucidate the value of IL-6 as a marker of disease activity, serum and CSF IL-6 levels of 68 BD patients with acute (26) or chronic progressive (14) parenchymal involvement (pNB), dural sinus thrombosis (10), ischemic stroke (5) or headache (13) were measured by ELISA. Samples from multiple sclerosis, subacute sclerosing panencephalitis, and noninflammatory neurological disorders were used as controls.
