Nanotechnology for Detection of Multiple Sclerosis Compared to Autoimmune and Neurological Diseases by Exhaled Samples
Multiple Sclerosis (MS) is a complex multi-factorial disease, with underlying both genetic and environmental factors. Different populations have different susceptibility to MS. The disease is characterized by 2 main phenotypes: relapsing-remitting or progressive course. Clinical disability is due to distraction of the central nervous system (CNS) myelin.
Repair processes are mainly noted after the acute relapse - and recovery of function can be spontaneous. However, in severe relapses sometimes there is need for STEROID TREATMENT.
For the long term prophylaxis - following the increased understanding of the disease, in the last 10-15 years, there are new immunotherapies available (COPAXON / TEVA; Interferon -beta). However these can attenuate the disease (reduce the number of relapses per year) but cannot cure it. Also, they are beneficial in only ~40 % of the Relapsing -Remitting patients.
Currently there are no biomarkers available for MS (other than oligoclonal Immunoglobulin G (IgG) in the cervical spine fluid (CSF) - which helps confirm diagnosis but require an invasive procedure and are not correlated with disease activity nor response to therapy) and monitoring of MS and its treatment is by magnetic resonance Imaging (MRI) - which is an expensive procedure.
Dr Hossam Haick from the Technion developed an electronic nose based on nanomaterials for diagnosis of diseases (e.g., cancer, kidney failure, etc.) via breath samples.The research hypothesis is that Biomarkers of CNS inflammation and/or neurodegeneration and/or CNS repair in persons with MS can be detected by the "electronic nose".

Diagnosis, breath and confounding factor
Other: NA-NOSE artificial olfactory system
NA-NOSE is an artificial olfactory system that is based on nanomaterials and connected with machine learning. NA-NOSE can diagnosis diseases or disorders based on volatile biomarkers that are emitted from exhaled breath, blood, or from clinical tissue.
