Abstract

A marker useful in diagnosing surgical site infections is provided. In the method of the present invention for detecting surgical site infections, sCD14-ST in a sample is measured.

Claims (24)

1. A method of detecting and treating surgical site infections not accompanied by systemic inflammatory response syndrome, comprising the steps of:

(A) collecting a sample from a patient after surgery suspected of having a surgical site infection not accompanied by systemic inflammatory response syndrome or a patient suffering from a surgical site infection not accompanied by systemic inflammatory response syndrome;

(B) measuring sCD14-ST in the sample;

(C) comparing the amount of sCD14-ST in the sample to a threshold value;

(D) diagnosing that the patient suffers from a surgical site infection not accompanied by systemic inflammatory response syndrome when an sCD14-ST value is higher than that of an uninfected person; and

(E) administering a treatment to the patient for the surgical site infection using an antimicrobial treatment.

2. The method according to claim 1 , wherein the sCD14-ST value is compared to the threshold previously determined selected from the group consisting of a healthy person group, a non-infection group, an infection group, a sepsis group, septic groups of different pathological level, and septic groups of different pathological types.

3. The method according to claim 1 , wherein sCD14-ST is measured by an immunoassay.

4. The method of claim 1 , wherein sCD14-ST is measured in the sample within about 7 to 10 days after surgery.

5. A method of detecting and treating surgical site infections not accompanied by systemic inflammatory response syndrome, comprising the steps of:

(A) collecting a sample from a patient after surgery suspected of having a surgical site infection not accompanied by systemic inflammatory response syndrome or a patient suffering from a surgical site infection not accompanied by systemic inflammatory response syndrome;

(B) measuring sCD14-ST in the sample by an immunoassay using a kit for detecting surgical site infections not accompanied by systemic inflammatory response syndrome, comprising:

(i) an antibody specific to sCD14-ST, said antibody being immobilized onto a latex carrier, magnetic particles or a substrate, or being labeled with a labeling substance,

(ii) standard data showing a correlation between the amount of sCD14-ST in a sample and surgical site infections not accompanied by systemic inflammatory response syndrome,

(C) comparing the amount of sCD14-ST in the sample to a threshold value;

(D) diagnosing that the patient suffers from a surgical site infection not accompanied by systemic inflammatory response syndrome when an sCD14-ST value is higher than that of an uninfected person; and

(E) administering a treatment to the patient for the surgical site infection using an antimicrobial treatment.

6. The method of claim 5 , wherein sCD14-ST is measured in the sample within about 7 to 10 days after surgery.

7. The method of claim 1 , wherein sCD14-ST is measured in the sample within about 5 to 10 days after surgery.

8. The method of claim 5 , wherein sCD14-ST is measured in the sample within about 5 to 10 days after surgery.

9. The method of claim 1 , wherein sCD14-ST is measured using a kit for detecting surgical site infections not accompanied by systemic inflammatory response syndrome, the kit comprising:

(a) an antibody specific to sCD14-ST, said antibody being immobilized onto a latex carrier, magnetic particles or a substrate, or being labeled with a labeling substance,

(b) standard data showing a correlation between the amount of sCD14-ST in a sample and surgical site infections not accompanied by systemic inflammatory response syndrome, and

(c) an instruction manual.
