Detection of inflammatory disease and composition for prevention or treatment of inflammatory disease
View Patent ↗A novel method for detection of an inflammatory disease and a novel composition for prevention or treatment of an inflammatory disease are provided. The method for detection of an inflammatory disease comprises using RANKL and/or OPG as a marker in a biological sample. The composition for prevention or treatment of an inflammatory disease comprises RANKL and/or M-CSF as an active ingredient.
1. A method for detection of a bacterial infectious disease or sepsis with use of RANKL as a marker in a biological blood sample, the method comprising:
(i) measuring by immunoassay a concentration of soluble RANKL in the biological blood sample isolated from a subject; and
(ii) determining that the subject is affected with the bacterial infectious disease or sepsis when the concentration of the soluble RANKL in the biological blood sample is lower than that of a normal subject,
wherein the bacterial infectious disease is a salmonella infectious disease, and
the sepsis is lipopolysaccharide or (LPS)-induced sepsis.
2. The method for detection of a bacterial infectious disease or sepsis according to claim 1 , wherein the method uses OPG in addition to RANKL as a marker in the biological blood sample, and the method comprises:
(i) measuring by immunoassay a concentration of OPG in the biological blood sample isolated from the subject in addition to the concentration of soluble RANKL; and
(ii) determining that the subject is affected with bacterial infectious disease or sepsis when a ratio of the concentration of the soluble RANKL relative to the concentration of the OPG in the biological blood sample is lower than the ratio of a normal subject.
3. The method for detection of a bacterial infectious disease or sepsis according to claim 2 , the method comprising a step of isolating the blood sample from the subject.
4. The method for detection of a bacterial infectious disease or sepsis according to claim 1 , the method comprising a step of isolating the blood sample from the subject.
