Application Number:	14/911,289
Patent Claims:	1. A method for diagnosing and treating first-attack multiple sclerosis in a patient, the method comprising: a) isolating a cerebrospinal fluid (CSF) sample from the patient; b) contacting the CSF sample with reagents specific for each of a panel of biomarkers to assess expression of the biomarkers, wherein the panel of biomarkers comprises Neural epidermal growth factor like 2/cerebral protein-12, Cerebellin-1, Nogo receptor, Dickkopf-3 (RIG-like 7-1), Brevican, Chitinase-3-like 1 protein, and Neogenin; and c) comparing expression of each of the biomarkers in the CSF sample to expression of each of the biomarkers, respectively, in a control CSF sample to determine if expression of any of the biomarkers in the CSF sample is increased or decreased relative to biomarkers in the control CSF sample, wherein detection of increased expression of any of Neural epidermal growth factor like 2/cerebral protein-12, Cerebellin-1, Nogo receptor, or Dickkopf-3 (RIG-like 7-1) in the CSF sample relative to expression for each biomarker, respectively, in a control CSF sample is, for each biomarker, a positive indicator of first-attack multiple sclerosis in the patient; and detection of decreased expression of any of Brevican, Chitinase-3-like 1 protein, or Neogenin in the CSF sample relative to expression for each biomarker, respectively, in a control CSF sample is, for each biomarker, a positive indicator of first-attack multiple sclerosis in the patient, and identification of at least two positive indicators in the patient serves to diagnose the patient as a first-attack multiple sclerosis patient; and treating the patient diagnosed with first-attack multiple sclerosis by administering a therapeutically effective amount of a disease modifying agent for treating multiple sclerosis. 2. The method of claim 1, wherein the reagents specific for each of the panel of biomarkers comprise antibodies. 3. The method of claim 1, further comprising processing the CSF sample prior to step b. 4. The method of claim 3, wherein the processing comprises immunodepletion of abundant proteins and sample concentration and/or proteolytic enzymatic digestion. 5. The method of claim 1, wherein the at least two positive indicators correspond to increased or decreased expression of three, four, five, six, or seven of the biomarkers in the CSF sample relative to the control CSF sample. 6. The method of claim 1, wherein the at least two positive indicators comprise increased expression of Neural epidermal growth factor like 2/cerebral protein-12 and Cerebellin-1. 7. The method of claim 1, wherein the increase or decrease is at least about a fold change of 1.1. 8. The method of claim 1, wherein the patient has experienced one of the common initial symptoms of multiple sclerosis comprising a vision problem, weakness, imbalance, or sensory problems. 9. The method of claim 1, wherein the disease modifying agent for treating multiple sclerosis is Aubagio (teriflunomide), Avonex (interferon beta-1a), Betaseron (interferon beta-1b), Copaxone (glatiramer acetate), Extavia (interferon beta-1b), Gilenya (fingolimod), Novantrone (mitoxantrone), Rebif (interferon beta-1a), Tecfidera (dimethyl fumarate), or Tysabri (natalizumab). 10. A method for diagnosing and treating first-attack multiple sclerosis in a patient, the method comprising: a) isolating a cerebrospinal fluid (CSF) sample from the patient; b) contacting the CSF sample with reagents specific for each of a panel of biomarkers to assess expression of the biomarkers, wherein the panel of biomarkers comprises Neural epidermal growth factor like 2/cerebral protein-12, Cerebellin-1, Neural cell adhesion molecule 2, Neuronal cadherin, Nogo receptor, Kallikrein-6 (Neurosin), Ceruloplasmin, Dickkopf-3 (RIG-like 7-1), Activated leukocyte cell adhesion molecule (CD166), Clusterin (Apolipoprotein J, complement lysis inhibitor), Brevican, Chitinase-3-like 1 protein, Neogenin, Multifunctional protein MFP, collagen alpha 1 (XVIII) chain (Endostatin), Dystroglycan 1, Contactin 2, Ephrin type A receptor 4, Neural cell adhesion molecule L1 like protein, and Contactin 1 and comparing expression of each of the biomarkers in the CSF sample to expression of each of the biomarkers, respectively, in a control CSF sample to determine if expression of any of the biomarkers in the CSF sample is increased or decreased relative to biomarkers in the control CSF sample, wherein detection of increased expression of Neural epidermal growth factor like 2/cerebral protein-12, Cerebellin-1, Nogo receptor, or Dickkopf-3 (RIG-like 7-1) in the processed CSF sample relative to expression for each biomarker, respectively, in a processed control CSF sample is, for each biomarker, a positive indicator of first-attack multiple sclerosis in the patient; and detection of decreased expression of Brevican, Chitinase-3-like 1 protein, or Neogenin in the processed CSF sample relative to expression for Neuronal cadherin in a processed control CSF sample is, for each biomarker, a positive indicator of first-attack multiple sclerosis in the patient, and identification of at least two positive indicators in the patient serves to diagnose the patient as a first-attack multiple sclerosis patient; and treating the patient diagnosed with first-attack multiple sclerosis by administering a therapeutically effective amount of a disease modifying agent for treating multiple sclerosis. 11. The method of claim 10, wherein the reagents specific for each of the panel of biomarkers comprise antibodies. 12. The method of claim 10, further comprising processing the CSF sample prior to step b. 13. The method of claim 10, wherein the at least two positive indicators correspond to increased or decreased expression of three, four, five, six, or seven of the biomarkers in the CSF sample relative to the control CSF sample. 14. The method of claim 10, wherein the at least two positive indicators comprise increased expression of Neural epidermal growth factor like 2/cerebral protein-12 and Cerebellin-1. 15. The method of claim 10, wherein the increase or decrease is at least about a fold change of 1.1. 16. The method of claim 10, wherein the disease modifying agent for treating multiple sclerosis is Aubagio (teriflunomide), Avonex (interferon beta-1a), Betaseron (interferon beta-1b), Copaxone (glatiramer acetate), Extavia (interferon beta-1b), Gilenya (fingolimod), Novantrone (mitoxantrone), Rebif (interferon beta-1a), Tecfidera (dimethyl fumarate), or Tysabri (natalizumab).
