Presepsin (soluble CD14 subtype) as a risk factor for the development of infectious and inflammatory complications in operated colorectal cancer patients

PURPOSE

In this pilot study the dynamic of presepsin (soluble CD14 subtype, sCD14-ST) in blood serum was assessed as a possible risk factor for the development of systemic inflammatory response syndrome (SIRS) and infectious and inflammatory complications in operated colorectal cancer patients.

METHODS

To determine sCD14-ST by enzyme-linked immunosorbent assay method venous blood was taken 1 hour before surgery and 72 hours after it (3rd day). The presence of SIRS and organ dysfunctions (ODs) according to the Sequential Organ Failure Assessment scale were assessed.

RESULTS

Thiry-six patients with colorectal cancer were enrolled in the study. sCD14-ST level before surgery was 269.8±103.1 pg/mL (interquartile range [IQR], 196.7-327.1 pg/mL). Despite the presepsin level on the 3rd day being higher (291.1±136.5 pg/mL; IQR, 181.2-395.5 pg/mL), there was no statistical significance in its dynamics (P=0.437). sCD14-ST value both before surgery and on the 3rd day after it was significantly higher in patients with bowel obstruction (P=0.038 and P=0.007). sCD14-ST level before surgery above 330 pg/mL showed an increase in the probability of complications, SIRS, and OD (odds ratio [OR], 5.5; 95% confidence interval [CI], 1.1-28.2; OR, 7.0; 95% CI, 1.3-36.7; and OR, 13.0; 95% CI, 1.1-147.8; respectively). Patients with OD had higher levels on the 3rd day after surgery (P=0.049).

CONCLUSION

sCD14-ST level in operated colorectal cancer patients was much higher if they were admitted with complication like bowel obstruction. Higher preoperative levels of sCD14-ST increase the probability of postoperative complications, SIRS, and OD. Therefore, further studies with large sample size are needed.

Lipopolysaccharide-binding protein as a risk factor for development of infectious and inflammatory postsurgical complications in colorectal cancer paients

Aim of the study

In this pilot study lipopolysaccharide-binding protein (LBP) levels were assessed as a possible risk factor for development of systemic inflammatory response syndrome (SIRS) and infectious and inflammatory complications in colorectal cancer (CRC) patients after surgery.

Material and methods

For LBP determination venous blood was taken 1 hour before the surgery and 72 hours after it. All patients were stratified by the presence or absence of acute bowel obstruction (ABO), SIRS and complications.

Results

36 patients with CRC participated in the study. The LBP level before surgery was 879.8 ± 221.8 ng/ml (interquartile range (IQR) 749.3-1028.8); on the 3^rd day it was 766.5 ± 159.4 ng/ml (IQR 669.5-847.6), which was a statistically significant decrease (p = 0.004). A decrease in LBP level by more than 280 ng/ml increases the probability of SIRS and complications in operated CRC patients (OR 6.6, 95% CI: 1.1-40.9 and OR 12.0, 95% CI: 1.8-80.4, respectively). In patients with ABO in the presence of SIRS, the LBP value decreased more than in those without SIRS (p = 0.046).

Conclusions

This study demonstrated that the LBP level in the operated CRC patients tends to decrease on the 3^rd day after surgery. A bigger decrease in LBP level increases the probability of SIRS and postoperative infectious and inflammatory complications. Therefore, further studies with larger numbers of patients are required.

Takes two to tango

A 17-year-old girl was admitted with acute abdominal pain, vomiting and a leucocytosis, and was initially thought to have appendicitis. She underwent laparoscopic appendicectomy, where the tip of the appendix was noted to be mildly inflamed and she was discharged home the day after surgery. Two days later, she re-presented with small bowel obstruction which was subsequently demonstrated to be due to ingestion of five magnetic beads. She required a laparotomy and small bowel resection to resolve the obstruction, but has since fully recovered. This case highlights the potential intestinal complications caused by the intake of magnetic objects, and based on a literature review a number of recommendations are made to guide clinicians when managing similar cases.
