Platelets and leucocytes are important effector cells of the haemostatic and inflammatory responses to tissue injury. To investigate the effects of surgical trauma on platelet activation (assessed by measuring levels of P-selectin and β-thromboglobulin), leucocyte activation (CD11b expression) and leucocyte-platelet interactions (leucocyte-platelet complexes), 30 patients undergoing primary hip arthroplasty were studied before and at the end of surgery, and on days 1 and 10 post-operatively, using a whole-blood flow cytometry assay. The inflammatory response was followed by measurement of the levels of C-reactive protein and interleukin-6 in plasma, and the activation of coagulation was monitored by determination of prothrombin fragment 1+2 levels. On day 1 post-operatively a significantly increased expression of CD11b on monocytes was noted, but no direct correlation was found between monocyte activation and interleukin-6 production or C-reactive protein at this time point. The percentage of monocyte-platelet and neutrophil-platelet complexes was markedly increased on day 10 post-operatively compared with pre-operative levels, and levels of these complexes were significantly positively correlated with β-thromboglobulin levels. Activation of coagulation (prothrombin fragment 1+2) on day 10 post-operatively was positively correlated with the extent of surgical trauma (duration of surgery, amount of blood loss) and with the increase in platelet activation (β-thromboglobulin). In conclusion, hip arthroplasty induces platelet and coagulation activation, and also an inflammatory response that is maintained for more than 10 days post-operatively. This indicates an interaction between the immune and the haemostatic systems in the post-operative phase after hip arthroplasty.

1. Recent studies have suggested that interleukin-6 is a major mediator of the acute-phase protein response in man. The aim of the present study was to investigate the relationships between the response of serum interleukin-6 to surgery, the type of surgical procedure performed and the response of serum C-reactive protein. 2. Timed venous blood samples were taken from 26 patients in five broad surgical categories (minor surgery, cholecystectomy, hip replacement, colorectal surgery and major vascular surgery). C-reactive protein and interleukin-6 were measured in each sample. 3. Serum interleukin-6 rose within 2–4 h of incision in all patients and the magnitude of the response differed among the various surgical groups. The response of interleukin-6 correlated (r = 0.80, P < 0.001) with the duration of surgery. In contrast, serum C-reactive protein was not detectable after minor surgery (< 10 mg/l) and the response of C-reactive protein did not differ among the more major surgical groups. The response of interleukin-6 showed a weak, but significant, correlation with the response of C-reactive protein (r = 0.67, P < 0.001). 4. We conclude that serum interleukin-6 is a sensitive, early marker of tissue damage. In general, the greater the surgical trauma, the greater the response of serum interleukin-6 and the greater the peak serum concentration of interleukin-6. Our results are consistent with a role for interleukin-6 in the induction of C-reactive protein synthesis.

1. On the basis of results from 3000 parallel measurements of serum amyloid A protein (SAA) and C-reactive protein (CRP) in various clinical and experimental conditions, the relationship between these proteins was examined and the question of whether measurements of SAA can provide clinically useful information beyond that from CRP assays was evaluated. 2. The concentrations of SAA and CRP showed a close relationship in a wide range of clinical conditions and the general clinical impact of an elevated SAA or CRP level is similar. SAA was, however, more sensitive than CRP in reflecting inflammatory activity, and in some conditions characterized by normal or only slightly elevated CRP concentrations, measurements of SAA concentrations could be used for monitoring disease activity and response to treatment. 3. Marked variation in the ratios of SAA to CRP concentration occurred in response to different stimuli (e.g. surgical trauma/immunological tissue injury), suggesting the existence of independent, disease-specific pathways of regulation for the serum concentrations of SAA and CRP.

Criteria of the systemic inflammatory response syndrome (SIRS) are known to include patients without systemic inflammation. Our aim was to explore additional markers of inflammation that would distinguish SIRS patients with systemic inflammation from patients without inflammation. The study included 100 acutely ill patients with SIRS. Peripheral blood neutrophil and monocyte CD11b expression, serum interleukin-6, interleukin-1β, tumour necrosis factor-α and C-reactive protein were determined, and severity of inflammation was evaluated by systemic inflammation composite score based on CD11b expression, C-reactive protein and cytokine levels. Levels of CD11b expression, C-reactive protein and interleukin-6 were higher in sepsis patients than in SIRS patients who met two criteria (SIRS2 group) or three criteria of SIRS (SIRS3 group). The systemic inflammation composite score of SIRS2 patients (median 1.5; range 0–8, n = 56) was lower than that of SIRS3 patients (3.5; range 0–9, n = 14, P = 0.013) and that of sepsis patients (5.0; range 3–10, n = 19, P< 0.001). The systemic inflammation composite score was 0 in 13/94 patients. In 81 patients in whom systemic inflammation composite scores exceeded 1, interleukin-6 was increased in 64 (79.0%), C-reactive protein in 59 (72.8%) and CD11b in 50 (61.7%). None of these markers, when used alone, identified all patients but at least one marker was positive in each patient. Quantifying phagocyte CD11b expression and serum interleukin-6 and C-reactive protein concurrently provides a means to discriminate SIRS patients with systemic inflammation from patients without systemic inflammation.

Fetal Inflammatory Response

Overview Objective: Fetal Inflammatory Response Syndrome (FIRS) is a serious complication accompanied by increased neonatal mortality and morbidity. Early dia­gnosis of FIRS is essential to detect high risk infants. The aim of the study was to evaluate the correlation between interleukin-6 
(IL-6), procalcitonin (PCT), C-reactive protein (CRP) in cord blood and histologically proven funisitis/ chorioamnionitis in high-risk infants after preterm birth. Methods: Blood sampling for the measurement of inflammatory bio­markers was performed immediately after placental delivery and umbilical cutting. Umbilical and placental inflammatory changes were assessed using a recently released scoring system (Amsterdam Placental Workshop Group Consensus). Results: One hundred preterm infants (30.5 ± 2.5 gestational week, birth weight 1,443 ± 566 grams) and 21 health term infants were analyzed. Histologic chorioamnionitis was confirmed in 19% cases and chorioamnionitis with funisitis in 7% cases. Thirty-three infants (33%) fulfilled criteria of FIRS (funistis and/ or umbilical IL-6 > 11 ng/ L). The presence of FIRS correlated significantly with maternal leukocytosis (P < 0.001), preterm premature rupture of membrane (P < 0.001) and preterm uterine contraction (P < 0.0001). In comparison to preterm and healthy term infants we found statistically significant higher levels of umbilical inflammatory bio­markers (IL-6, PCT, CRP) in FIRS group (P < 0.0001). Composite mortality and morbidity (bronchopulmonary dysplasia, intraventricular haemorrhage, periventricular leukomalacia) was higher in FIRS group (28.1 vs 22.4% in preterm group). However, the difference was not statistically significant (P = 0.53). Conclusion: Our study confirmed the correlation of umbilical inflammatory bio­markers levels (IL-6, PCT, CRP) and the presence of FIRS. We did not find significant adverse impact of FIRS on neonatal mortality and morbidity. Nevertheless, our results could be influenced by the size of study group and strict inclusion criteria (only cases after C-section were analyzed).

SummaryDisseminated intravascular coagulation (DIC) is a frequent complication of septicemia or tissue injury and may be accompanied by elevations of interleukin-6, a mediator of the acute phase response. It is not known whether thrombin or fibrin deposition may directly induce an acute phase response. To study this, we employed a baboon model of in vivo thrombin generation, induced by the administration of purified bovine Factor Xa and phospholipid vesicles. Two Xa/phospholipid dosages were used, a low dosage (2 animals) leading to a rapid 49% decrease in fibrinogen and a high dosage (two injections at 5h interval; 3 animals) leading to complete fibrinogen depletion. Thereafter, fibrinogen levels increased in both treatment groups, reached a maximum of 2.52 ± 0.23 g/1 (mean ± SE, n = 5; p <0.01 with respect to basal levels) at day 2, and returned to normal by day seven. In five control (injection of 0.15% NaCl) baboons no significant changes of fibrinogen were observed (maximal values: 1.88 ± 0.12 g/1). Serum concentrations of C-reactive protein, an acute phase protein, increased from 3.7 ± 0.4 mg/1 to a maximum of 33.0 ± 7.3 at day one, which was five-fold higher (p <0.01) than in control animals at day one (6.2 ± 0.5 mg/1). Transient increases were observed within 6 h for interleukin-6 from basal values of 6.2 ± 1.7 ng/1 to peak plasma levels of 42.9 ±21.4 ng/1, a value threefold higher (p = 0.07) than in control animals (14.8 ± 4.0 ng/1).The preliminary results of this observational study suggest that factor Xa/phospholipid infusion is followed by an acute phase response, leading after one day to significant increases of fibrinogen and of C-reactive protein.

BACKGROUND: Ozone as a strong oxidant may induce an inflammatory response.Aim: The hypothesis was verified as to whether ozonated autohemotherapy using an ozone dose in therapeutic range changes the plasma concentration of C-reactive protein and interleukin-6, markers of inflammation.Methods: In a controlled, single-blind, cross-over study, 12 chronically hemodialyzed patients with peripheral arterial disease were exposed to nine sessions of autohemotherapy with blood exposure to oxygen as a control followed by nine sessions of ozonated autohemotherapy with an ozone concentration of 50 μg/ml.Results: There was no statistical difference between C-reactive protein levels at baseline (1.53±1.01 mg/l), after nine sessions of control autohemotherapy (1.48±0.96 mg/l), and after nine sessions of ozonated autohemotherapy (1.55±0.84 mg/l). There was also no statistical difference between the interleukin-6 serum concentration at baseline (438±118 pg/ml), after nine sessions of control autohemotherapy (444±120 pg/ml), and after nine sessions of ozonated autohemotherapy (466±152 pg/ml).Conclusion: The results of this study suggest that ozonated autohemotherapy using an ozone concentration of 50 μg/ml does not induce an inflammatory response.
