  • Patent number: 10294509
    Abstract: To provide a method for simply measuring ethanolamine phosphate in a sample, and a reagent, kit, program and the like useful in the method. A measurement method of ethanolamine phosphate includes a first step of adding an enzyme, which can catalyze a reaction that forms acetaldehyde from ethanolamine phosphate, to a sample, and conducting a first enzymatic reaction to form acetaldehyde, phosphoric acid and ammonia; and a second step of quantifying at least one of the resultant acetaldehyde, phosphoric acid and ammonia to determine an amount of the ethanolamine phosphate in the measurement sample.

  • Publication number: 20170176412
    Abstract: A method for predicting options of depression treatment drugs includes (a) measuring a phosphoethanolamine (PEA) level in blood collected from a patient suspected of depression, (b) measuring whether the blood PEA level of the patient is lower than a reference value or not, wherein if the measured value of the patient is lower than values of healthy persons, the patient suffers from depression exhibiting a decreased PEA level as an indicator, and (c) predicting options of depression treatment drugs on the basis of the presence or absence of decreased blood PEA level in the patient. Thus, PEA, which is a biomarker of depression, can be directly linked to treatment.

  • Patent number: 9442121
    Abstract: A method for treating depression using a biomarker includes measuring a level of phosphoethanolamine in a blood sample collected from a subject, comparing the level of phosphoethanolamine in the blood sample with a predetermined threshold, in response to the level of phosphoethanolamine in the blood sample being below the predetermined threshold, determining that the subject requires a treatment for depression, and treating the subject determined to suffer from depression.
