“…It is a sensitive but non-specific inflammatory biomarker often used as an indicator for systemic inflammatory response syndrome (SIRS) [1], [2] secondary to surgery or early postoperative complications [3]. However, its role as predictor for clinical deterioration in the surgical critically ill patient in the intensive care unit (ICU) remains unspecific.…”

“…Studies about the value of CRP in the critically ill patient on the ICU are contradictory. Increased CRP concentrations in a heterogeneous population on the ICU have been associated with organ failure, prolonged ICU stay, high infection rates and mortality rates [3], [5], [6]. On the contrary, a recent review on the predictive value of CRP concentrations for survival concluded that CRP is not a good predictor for survival in the critically ill patient during the early course.…”

“…An increase in CRP levels has been described as a crucial indicator for the diagnosis of postoperative complications in surgical patients such as infection, SIRS, sepsis, anastomotic leakage or mesenterial ischemia [8], [9], [10]. In addition, in patients with CRP levels >140 mg/L on the 4th postoperative day after rectal surgery with primary anastomosis, a 90.5% positive predictive value for postoperative infection was measured [3], [9], [11]. However, CRP concentrations change throughout the postoperative course in both subjects with or without complications, and they are not specific for any kind of complications [9].…”
IntroductionC-reactive Protein (CRP) is used next to clinical scoring systems to recognize critically ill patients prone to develop complications on the Intensive Care Unit (ICU). The purpose of this study is to assess the predictive value of CRP as parameter for clinical deterioration and/or clinical decision making as ordering diagnostic procedures or performing (re)interventions. Also, we wanted to determine the value of CRP in early detection of surgical complications in the critically ill general surgical patient in the ICU and its interpretation in adjunct to a clinical scoring system, the Sequential Organ Failure Assessment Score.Materials and MethodsIn our prospective observational study, 174 general surgical patients admitted into the Intensive Care Unit were included. We evaluated the Sequential Organ Failure Assessment Score (SOFA) and daily measured the C-reactive protein (CRP) concentrations. All events (diagnostic or therapeutic interventions) and surgical complications were registered. Then the relationship between SOFA score, CRP concentrations, events and complications were studied.ResultsEach 10% increase in CRP resulted in a 3.5% increase in the odds of an event (odds ratio 1.035, 95% CI: 1.004–1.068; p = 0.028). However, an increase in CRP levels did not lead to a higher odds of complication (OR 0.983, 95% CI: 0.932–1.036; p = 0.52). When adjusting for the SOFA score the effect of CRP on the probability of a first event remained significant (OR 1.033, 95% CI: 1.001–1.065; p = 0.046), and again did not significantly affect the complication probability (OR 0.980, 95% CI: 0.929–1.035; p = 0.46).ConclusionsAn increase in C-reactive protein is a poor parameter for early detection of complications in the critically ill surgical patient in the ICU by means of diagnostic procedures or therapeutic (re)-interventions.

“…Obese patients may present high CRP values due to the chronic inflammatory condition developed by the increase of interleukin-6 and tumor necrosis factor in adipocytes, promoting the production of C-reactive protein by hepatocytes, inducing a state of chronic inflammation 3 , 14 , 23 . Due to the PCR/adipocyte ratio, it has been speculated that weight loss may decrease the chronic inflammatory state 21 . Increased inflammatory markers have been the focus of many studies, with emphasis on adipose tissue in obese patients as a causal factor of cardiovascular events 12 .…”
Background: PCR (C-reactive protein), produced in the liver after stimuli of inflammatory
mediators, is determined as a marker of inflammatory activity
(adipocytokines) and is present within adipocyte cells; besides being an
inflammatory product, many studies have shown to be a predictor of
complications. Aim: To determine if the inflammatory state of the obese patient decreases after
bariatric surgery, based on pre and post-operative PCR. Methods: A prospective, observational study in patients undergoing Roux-en-Y gastric
by-pass surgery followed up for three months after surgery, with serum
preoperative CRP in 30, 60 and 90 days after surgery. Results: A total of 19 patients, who had a mean CRP value before the surgical
procedure of 0.80(±0.54) mg/dl, were followed, and when compared to the CRP
with 30 days of surgery, they presented a significant increase to 2.68 mg/dl
(p=0.012). When compared with the PCR of 60 days after the surgical
procedure, it was also higher with the value of 3.32 mg/dl (p=0.27).
However, at three months after surgery, the CRP showed a decrease when
compared to the preoperative mark, with value of 0.45 mg/dl (p=0.0042). Conclusion: Roux-en-Y gastric bypass was able to decrease the chronic inflammation status
of these patients, based on the value of CRP, with three months of
surgery.
“…Por se tratar de uma proteína não específica para infecção, uma metanálise conclui que utilização de proteína-C-reativa deve ser acompanhada de exames clínicos, o que não exclui seu valor como preditor de infecções (96). Em ensaio randomizado comparando ambos, não houve significativa diferença na redução de terapia antimicrobiana, mas a procalcitonina foi superior em reduzir os dias de terapia antimicrobiana e é demonstrado também em alguns estudos seu potencial em reduzir mortalidade (97) (98).…”
