To determine the role of neurofilament light chain in Behçet's disease with or without neurological affection and its relation to neurological manifestation (either peripheral or central ).
Behçet disease is a multisystemic autoinflammatory disorder characterized by recurrent oral and genital ulcer, eye affection, thrombosis and many systems can be affected with the most serious being the nervous system affection which is commonly called neuro-Behçet's disease (NBD) In Ghita et al, the prevalence of Behcet disease in Egypt was estimated to be 3.6/100,000 with CNS affection occurred in about 13.1% of the patients , while in other study performed in Egypt the peripheral neuropathy affection reached 53.3% of the patients with insignificant difference between both upper and lower limb but sensory affection was manifested more than motor affection in those patients.
Neurofilament light chain (NFL) is a neuronal cytoplasmic protein, which was assumed to have a role as a prognostic biomarker in several neuroimmunological and neurodegenerative diseases. It was documented in peripheral nerve affection of patients with diabetes mellitus and GuillainBarré syndrome. Recently, some studies documented the presence of high level of NFL chain in serum of neurolupus and primary sjogren's diseases , more over in 2022, Karaaslan et al. measured NFL in the cerebrospinal fluid (CSF) and found it high in neurobehcet patients and assumed that it can predict the prospective cognitive and somatic disability in NBD patients.
So, the investigators aim at our study to assess the role of NFL chain in serum of behcet disease in those with and without peripheral and central nervous system affection and its relation to neurological manifestation.
