Abstract
Disclosed is a method for assisting prediction of exacerbation of respiratory infection, comprising measuring a biomarker in a specimen collected from a subject suffering from a respiratory infection or a subject suspected of having a respiratory infection, wherein the biomarker is at least one selected from the group consisting of IFNλ3, CCL17, CXCL11, IP-10, IL-6 and CXCL9, and a measured value of the biomarker is used as an index to predict exacerbation of the respiratory infection.
Claims11
A method for assisting prediction of exacerbation of a respiratory infection, comprising:
- measuring a biomarker in a specimen collected from a subject suffering from the respiratory infection or a subject suspected of having the respiratory infection, wherein the biomarker is one or more of IFNλ3 and CCL17, and a measured value of the biomarker is an index to predict exacerbation of the respiratory infection of the subject,
- identifying a subject having the measured value of IFNλ3 greater than or equal to a threshold value corresponding to IFNλ3, and/or the measured value of CCL17 less than a threshold value corresponding to CCL17,
- wherein a possibility of exacerbation of the respiratory infection of the subject is suggested to be high if the biomarker is IFNλ3 and the measured value of IFNλ3 is greater than or equal to a threshold value corresponding to IFNλ3, and/or if the biomarker is CCL17 and the measured value of CCL17 is less than a threshold value corresponding to CCL17, and
- administering to said subject an antiviral drug, an anti-inflammatory drug or an ACE inhibitor capable of treating the respiratory infection.
A method for assisting prediction of exacerbation of a respiratory infection, comprising:
- monitoring a measured value of a biomarker in a specimen collected from a subject suffering from the respiratory infection or a subject suspected of having the respiratory infection,
- the monitoring comprising:
- acquiring measured values of the biomarker using specimens collected from the subject at a plurality of time points,
- wherein the biomarker is one or more of IFNλ3 and CCL17, and the measured values are indices to predict exacerbation of the respiratory infection of the subject,
- identifying a subject having the measured value of IFNλ3 greater than or equal to a threshold value corresponding to IFNλ3 at at least one of the plurality of time points, and/or the measured value of CCL17 less than a threshold value corresponding to CCL17 at at least one of the plurality of time points,
- wherein a possibility of exacerbation of the respiratory infection of the subject is suggested to be high if the biomarker is IFNλ3 and the measured value of IFNλ3 is greater than or equal to a threshold value corresponding to IFNλ3 at at least one of the plurality of time points, and/or if the biomarker is CCL17 and the measured value of CCL17 is less than a threshold value corresponding to CCL17 at at least one of the plurality of time points, and
- administering to said subject an antiviral drug, an anti-inflammatory drug or an ACE inhibitor capable of treating the respiratory infection.
