Treating schizophrenia based on a panel of biomarkers
The invention relates to a method of differential diagnosis of schizophrenia or other psychotic disorder from a further psychiatric disorder.
1. A method of treating an individual suspected of suffering from schizophrenia, or a predisposition thereto, comprising:
a) obtaining a biological sample of an individual with a psychiatric disorder who has not been diagnosed with schizophrenia;
b) quantifying concentrations of a panel of biomarkers in the biological sample by subjecting the sample to SELDI (-TOF) spectrometry, MALDI (-TOF) spectrometry, a 1-D gel-based analysis, a 2-D gel-based analysis, mass spectrometry (MS), liquid chromatography (LC), reverse phase liquid chromatography (RP-LC), size permeation chromatography, gel filtration chromatography, ion exchange chromatography, affinity chromatography, FPLC, HPLC, UPLC, other LC-based techniques, other LC-MS-based techniques, or combinations thereof; or
an immunological method, a biosensor method, a microanalytical method, a microengineered method, a microseparation method, an immunochromatography method, or combinations thereof;
and
c) administering an antipsychotic agent to the individual showing a biomarker profile having a higher level of a set of biomarkers from the panel as compared to a normal control,
wherein the set of biomarkers consists of α2 Macroglobulin (A2M), α1 Antitrypsin (α1AT), Angiopoietin 2 (ANG2), Brain derived neurotrophic factor (BDNF), Betacellulin, Bone morphogenic protein 6 (BMP6), Carcinoembryonic Antigen (CEA), CD40 Ligand (CD40L), Cortisol, Connective tissue growth factor (CTGF), Epidermal growth factor (EGF), Eotaxin 3, Factor VII, Follicle stimulating hormone (FSH), GM-CSF, Glutathione S transferase (GST), Haptoglobin (HPT), ICAM 1, IGFBP 2, Interleukin 10 (IL 10), IL 17, IL 5, Luteinizing Hormone (LH), MIF, NrCAM, Pancreatic Polypeptide (PP), Prostatic acid phosphatise (PAP), RANTES (C—C motif chemokine 5), Resistin, SGOT, Sortilin, Stem Cell Factor (SCF), Thrombopoietin (TPO) and Thrombospondin 1 (TSP1).
2. The method of claim 1 , wherein the quantifying is performed on two or more occasions.
3. The method of claim 2 , wherein the quantifying is performed prior to the administering.
4. The method of claim 2 , wherein the quantifying is repeated at intervals throughout the individual's lifetime.
5. The method of claim 1 , wherein the administering further comprises at least one therapy selected from the group consisting of psychotherapy, counseling, hospitalization, electroconvulsive therapy, and combinations thereof.
6. A method of treatment comprising:
a) obtaining a biological sample of an individual with a psychiatric disorder having symptoms of bipolar disorder, Asperger syndrome, or major depressive disorder that overlap with schizophrenia and who has not been diagnosed with schizophrenia; and
b) quantifying concentrations of a panel of biomarkers in the biological sample by subjecting the sample to SELDI (-TOF) spectrometry, MALDI (-TOF) spectrometry, a 1-D gel-based analysis, a 2-D gel-based analysis, mass spectrometry (MS), liquid chromatography (LC), reverse phase liquid chromatography (RP-LC), size permeation chromatography, gel filtration chromatography, ion exchange chromatography, affinity chromatography, FPLC, HPLC, UPLC, other LC-based techniques, other LC-MS-based techniques, or combinations thereof; or
an immunological method, a biosensor method, a microanalytical method, a microengineered method, a microseparation method, an immunochromatography method, or combinations thereof;
(c) administering an antipsychotic agent to the individual showing a biomarker profile having a higher level of a set of biomarkers from the panel as compared to a normal control;
wherein the set of biomarkers consists of α2 Macroglobulin (A2M), α1 Antitrypsin (α1AT), Angiopoietin 2 (ANG2), Brain derived neurotrophic factor (BDNF), Betacellulin, Bone morphogenic protein 6 (BMP6), Carcinoembryonic Antigen (CEA), CD40 Ligand (CD40L), Cortisol, Connective tissue growth factor (CTGF), Epidermal growth factor (EGF), Eotaxin 3, Factor VII, Follicle stimulating hormone (FSH), GM-CSF, Glutathione S transferase (GST), Haptoglobin (HPT), ICAM 1, IGFBP 2, Interleukin 10 (IL 10), IL 17, IL 5, Luteinizing Hormone (LH), MIF, NrCAM, Pancreatic Polypeptide (PP), Prostatic acid phosphatise (PAP), RANTES (C—C motif chemokine 5), Resistin, SGOT, Sortilin, Stem Cell Factor (SCF), Thrombopoietin (TPO) and Thrombospondin 1 (TSP1).
7. The method of claim 6 , wherein the quantifying is performed on two or more occasions.
8. The method of claim 7 , wherein the quantifying is performed prior to the administering.
9. The method of claim 7 , wherein the quantifying is repeated at intervals throughout the individual's lifetime.
10. The method of claim 6 , wherein the administering further comprises at least one therapy selected from the group consisting of psychotherapy, counseling, hospitalization, electroconvulsive therapy, and combinations thereof.
11. A method of treatment comprising:
a) obtaining a biological sample of an individual who displays symptoms of a psychiatric disorder that has overlapping symptoms with schizophrenia and has not been diagnosed with schizophrenia;
b) quantifying concentrations of a panel of biomarkers in the biological sample by subjecting the sample to SELDI (-TOF) spectrometry, MALDI (-TOF) spectrometry, a 1-D gel-based analysis, a 2-D gel-based analysis, mass spectrometry (MS), liquid chromatography (LC), reverse phase liquid chromatography (RP-LC), size permeation chromatography, gel filtration chromatography, ion exchange chromatography, affinity chromatography, FPLC, HPLC, UPLC, other LC-based techniques, other LC-MS-based techniques, or combinations thereof; or
an immunological method, a biosensor method, a microanalytical method, a microengineered method, a microseparation method, an immunochromatography method, or combinations thereof;
(c) administering an antipsychotic agent to the individual showing a biomarker profile having a higher level of a set of biomarkers from the panel as compared to a normal control;
