Procalcitonin, neopterin and C-reactive protein after pediatric cardiac surgery with cardiopulmonary bypass

Bratislavské lekárske listy, 2007

Kinetics of activation of newly introduced inflammatory markers is of particular value in their use in postoperative setting after pediatric cardiac surgery. To assess the influence of cardiopulmonary bypass (CPB) on activation of inflammatory markers. Procalcitonin, neopterin and C-reactive protein (CRP) blood levels were measured before, on day 1 and day 2 after surgery in 152 pediatric patients undergoing cardiac surgery with CPB. All patients had infection-free postoperative course. Procalcitonin blood levels increased from 0.08 (0.001-0.19) ng/mL before surgery to 0.79 (0.13-3.5) ng/mL on day 1 (p < 0.001) and 0.52 (0.07-2.7) ng/mL on day 2 (p < 0.001) after surgery. Procalcitonin levels on day 1 correlated with CPB duration, cross-clamping time and use of aprotinin. Neopterin values increased from 8.4 (4.4-32) nmol/L before surgery to 16.1 (6.8-37.6) nmol/L on day 1 (p < 0.001) and 10.9 (5.3-31.1) nmol/L on day 2 (p < 0.001) after surgery. Neopterin levels on day 1...

Is C-Reactive Protein a Biomarker for Immediate Clinical Outcome After Cardiac Surgery?

Journal of Cardiothoracic and Vascular Anesthesia, 2009

The purpose of this study was to determine the possible correlation between inflammatory activation after cardiac surgery with cardiopulmonary bypass, measured by postoperative C-reactive protein concentrations, and immediate intensive care unit outcome. Design: A prospective, clinical cohort study. Setting: A 10-bed surgical intensive care unit at a tertiary university hospital. Patients: Two hundred sixteen consecutive patients undergoing nonemergency cardiac surgery with cardiopulmonary bypass. Measurements and Main Results: Parsonnet and Acute Physiology and Chronic Health Evaluation scores, characteristics of the surgical intervention, intensive care unit length of stay, and mortality were recorded along with the following variables: cardiac (hours requiring inotropic support and new atrial fibrillation), respiratory (oxygenation index and hours requiring intubation), renal (difference between serum creatinine at admission and maximum creatinine), and analytic (C-reactive protein at admission and 6, 24, and 48 hours later; troponin I; CK-MB; and lactate). Results: Postoperative C-reactive protein concentrations did not correlate with variables such as time requiring inotropic support or intubation, oxygenation index, delta serum creatinine, and intensive care unit length of stay (with the exception of cardiopulmonary bypass time and the more frequent norepinephrine requirement in patients with higher C-reactive protein concentration at 48 hours); nor did Creactive protein correlate with the analytic variables (with the exception of the lactate peak and C-reactive protein concentrations at 24 and 48 hours). There was no correlation between C-reactive protein and postoperative variables for coronary artery bypass graft surgery and valvular groups analyzed separately. Conclusion: Postoperative C-reactive protein does not seem to be a useful marker in predicting outcome after 48 hours in the intensive care unit.

Preoperative C-reactive protein level and outcome following coronary surgery

European Journal of Cardio-Thoracic Surgery, 2002

Objective: It has been suggested that a preoperative level of C-reactive protein (CRP) . 5 mg/l is predictive of postoperative complications in cardiac surgery patients. Material and methods: Among 113 primary isolated coronary artery bypass patients, CRP was determined preoperatively and fibrinogen, interleukine 6, plasminogen activator inhibitor-1, prothrombin time, activated partial thromboplastin time, platelets and white blood cells count measured before surgery, 24, 48 and 72 h thereafter and at hospital discharge. The clinical course of all cases was prospectively recorded. Data were then analysed according to the preoperative CRP level by dividing the patients into two groups (CRP . 5 mg/l or CRP , 5 mg/l). Results: The in-hospital results were similar between the two patients groups. Even the postoperative haematic inflammatory markers did not significantly differ according to the preoperative CRP level. Conclusion: In this prospective study, a preoperative level of CRP . 5 mg/l did not predict in-hospital postoperative complications nor influence the extent of the inflammatory activation in primary isolated coronary bypass patients. q

Release of Cardiac Biochemical and Inflammatory Markers in Patients on Cardiopulmonary Bypass Undergoing Coronary Artery Bypass Grafting

Journal of Cardiac Surgery, 2008

Background: Determination of cardiac markers can assess cardiac injury induced by cardiopulmonary bypass (CPB) during coronary artery bypass grafting (CABG). However, the markers and their release pattern are not well defined. This study was aimed at assessing the release and timing of cardiac biochemical and inflammatory markers in patients undergoing elective CABG with CPB. Methods: Forty patients undergoing elective CABG were included in this study. Blood samples were collected for biochemical measurements at the following time points: immediately prior to the induction of anesthesia, one, six, 12, and 24 hours after initiation of CPB. Results: Increased release of cardiac troponin I was observed one hour after initiation of CPB (p < 0.05) and reached the maximum at 12 hours after CPB (p < 0.01). Serum CK-MB enzyme activity and CK-MB mass both were highly elevated starting at one hour after initiation of CPB, peaked at six hours, and remained elevated until 24 hours after CPB. Both lactate and lactate dehydrogenase were highly elevated six hours after CPB and peaked at 12 hours after CPB (p < 0.01). Serum levels of interleukin-6 and tumor necrosis factor-α increased significantly one hour after initiation of CPB and peaked at six hours (p < 0.01), while serum high sensitivity C-reactive protein levels started to elevate 12 hours after CPB (p < 0.01). Conclusion: Monitoring of these markers could help to determine implementation of protective interventions during CABG with CPB to prevent myocardial deterioration and to predict the risk and prognosis.

Elevated Levels of Procalcitonin and Interleukin-6 are Linked with Postoperative Complications in Cardiac Surgery

Scandinavian Journal of Surgery, 2017

Background: Cardiac surgery–associated acute kidney injury is a frequent and serious postoperative complication of cardiac surgery and is associated with an increased risk of morbidity, mortality, and length stay. In this study, we hypothesized that persistent elevation in inflammation in the first 48 h might be a powerful predictor of clinical outcome. Our aim was to elucidate the usefulness of interleukin-6 and procalcitonin postoperative levels in predicting mortality and renal complications in cardiac surgery patients. Methods: A total of 122 cardiac surgery patients were enrolled. Procalcitonin and interleukin-6 concentrations were measured on the second postoperative day, and their levels were evaluated versus a number of conditions and endpoints. Results: Procalcitonin has a good predictive value for adverse renal outcome (p < 0.05). Interleukin-6 has a good predictive value for 30 days and overall mortality in cardiac surgery population (p < 0.05). We did not observe a...

Kinetics of procalcitonin, interleukin 6 and C-reactive protein after cardiopulmonary-bypass in children

Cardiology in the Young, 2003

Cardiopulmonary bypass induces a generalized inflammatory response, with fever and leukocytes, which is difficult to differentiate from an infection. Recently, procalcitonin has been proposed as an early and specific marker of bacterial infection. The influence of cardiopulmonary bypass on production of procalcitonin, therefore, must be assessed before considering this molecule as a valuable marker of infection after cardiac surgery in children. With this in mind, we measured levels of procalcitonin, interleukin 6, and C-reactive protein before and 6 h, 1, 3 and 5 days after cardiopulmonary bypass, in 25 children undergoing cardiac surgery. Cardiopulmonary-bypass induced a transient increase in procalcitonin, with a peak at 24 h, with a median of 1.13 μg/l, a 25th and 75th interquartile of 0.68–2.25, and a p value of less than 0.001. The value had returned to normal in the majority of the children by the third day after surgery. Peak values correlated with the duration of cardiopulm...
