Increase of interleukin-6 plasma levels after elective craniotomy: Influence of interleukin-10 and catecholamines

Summary Accidental and operative trauma are able to induce a systemic reaction of the organism characterized by fever, leukocytosis, catabolism, and an activation of the coagulation system. Interleukin-6 (IL-6) has been found to be an important mediator of this acute-phase response. In this study the influence of elective craniotomy on IL-6 plasma levels was evaluated. Blood samples were obtained from 20 patients undergoing elective craniotorny for vascular or tumorous diseases of the brain. IL-6 increased significantly (p < 0.05) from the pre-operative (0 (0–5.4) pg/ml) to the intraoperative (180 min after beginning of surgery) time-point (10.6 (0–18.5) pg/ml). The maximum was reached on the first postoperative morning (13.9 (4.3–45.0) pg/ml). Interleukin-10 (IL-10) is an anti-inflammatory cytokine which suppresses IL-6 synthesis in vitro in various cell lines. IL-10 plasma concentrations showed no alterations throughout the study period. Epinephrine plasma concentrations increased significantly from pre-operative values (15 (0–74) pg/ml) to the postoperative time-point (57 (9–459) pg/ml). A 4.5-fold increase (p < 0.05) of norepinephrine plasma concentrations was found when comparing the data obtained 60 min after beginning of surgery with the data of the first postoperative morning. In monocytes, which are a major source of plasma IL-6, an elevation of intracellular cAMP stimulates the IL-6 synthesis. The postoperative maximum of IL-6 in plasma could be due to a release of catecholamines. In conclusion this study demonstrated an elevation of IL-6 plasma concentrations during and after elective craniotomy. Increased plasma catecholamine concentrations as well as a damage in the blood-brain barrier due to the surgical trauma with a spill-over of IL-6 from brain tissue into plasma could have contributed to this result.

Comparison of surgical stress between laparoscopy and open surgery in the field of urology by measurement of humoral mediators

BACKGROUND: Recently, laparoscopic procedures have become more common in urological surgery, and are suggested to be less stressful compared with open surgery; however, little data on objective evaluation of surgical stress after laparoscopic surgery are available. The objective of this study was to compare surgical stress between laparoscopic and open surgery in the field of urology by measurement of humoral mediators. METHODS: Blood samples were obtained from 25 patients who underwent laparoscopic surgery (laparoscopic radical prostatectomy, 10; retroperitoneoscopic nephrectomy or nephroureterectomy, seven; laparoscopic adrenalectomy, five; and hand-assisted laparoscopic radical nephrectomy, three) and 10 who underwent open surgery (retropubic radical prostatectomy, four; radical cystectomy, three; and radical nephrectomy, three), 48 h before surgery, during surgery, and 24, 48 and 96 h after surgery. Serum levels of interleukin (IL)-6, IL-10 and granulocytic elastase in these samples were measured, and the results were analyzed with respect to several clinical factors. RESULTS: In both groups, IL-6 and granulocytic elastase levels increased during surgery and reached maximum levels 24 h after surgery; the increase in granulocytic elastase tended to be prolonged compared with that of IL-6. Changes in IL-10 levels in the open surgery group were similar to those of IL-6 and granulocytic elastase levels, whereas IL-10 levels in the laparoscopic surgery group reached a maximum level during surgery and then decreased to the same level as at 48 h before surgery, on the first postoperative day. The maximum levels of these three mediators in the laparoscopic surgery group were significantly lower than those in the open surgery group. IL-6 was closely associated with the interval of fasting and duration of hospitalization after surgery. CONCLUSION: Although the present study was based on retrospective and non-randomized analysis, the findings suggest that serum levels of IL-6, IL-10 and granulocytic elastase are useful as objective markers of surgical stress, and that laparoscopic surgery is markedly less stressful than open surgery.     

Lower prevalence of IL-4 receptor alpha-chain gene G variant in very-low-birth-weight infants with necrotizing enterocolitis

Background/purpose: Altered production of immunoregulatory cytokines is associated with the development of necrotizing enterocolitis (NEC) in preterm very low-birth-weight (VLBW) infants. According to data obtained in adults, functional genetic polymorphisms influence cytokine production capacity. The aim of this study was to evaluate whether functional polymorphisms of interleukin (IL)-1β, IL-4 receptor α-chain (IL-4ra), IL-6, and IL-10 genes might be associated with the risk of NEC in VLBW infants.Methods: Dried blood spot samples of 46 VLBW infants with NEC were analyzed using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) methods. Samples from 90 VLBW infants without NEC were used as controls.Results: Infants with NEC carried the mutant variant of IL-4ra less frequently than controls (0.125 v 0.224; P < .05) even after adjustment for risk factors of NEC. No significant differences were found in the allelic frequencies of IL-1β, IL-6, and IL-10 genes between NEC and control infants.Conclusions: Carrier state of IL-4ra mutant allele might be associated with lower risk of NEC in VLBW infants. This genetic variant is associated with enhanced IL-4 effect. IL-4 is a major regulator of Th1-Th2 shift. The authors hypothesize that infants carrying the IL-4ra mutant allele might have Th2 skewness that might defend against the development of NEC.

Pre-transplant elevations of interleukin-12 and interleukin-10 are associated with acute rejection after renal transplantation

BACKGROUND: Methods for predicting patients at higher risk for rejection before transplantation may help improve outcomes. We hypothesized that pre-transplant elevations of serum interleukin-12 (IL-12), a pro-inflammatory cytokine, would predict acute rejection, while pre-transplant IL-10, an immunoregulatory cytokine, would be down-regulated in patients subsequently experiencing acute rejection. MATERIALS AND METHODS: Thirty patients experiencing acute rejection after cadaveric renal allograft transplantation and a control group of 30 patients, undergoing the same procedure but without the occurrence of rejection, were identified. Serum samples taken before transplantation from each patient were then analyzed quantitatively for IL-12 and IL-10 using ELISA assays. RESULTS: The mean pre-transplant serum IL-12 level was higher in patients who subsequently underwent acute rejection vs. those who did not (181 +/- 143 pg/mL vs. 81.2 +/- 71.5 pg/mL, respectively, p = 0.007). Unexpectedly, pre-transplant serum IL-10 levels were also elevated in patients who underwent rejection (559 +/- 293 pg/mL vs. 332 +/- 163 pg/mL, respectively, p = 0.002). Multivariate analysis demonstrated that elevations of IL-12 and IL-10 were independent risk factors for rejection when adjusted for confounding variables. CONCLUSIONS: Pre-transplant elevations of IL-12 and, unexpectedly, IL-10 are associated with acute rejection after cadaveric renal transplantation and may be useful in predicting which patients are at increased immunological risk at the time of transplantation. Further studies are necessary to assess the role of occult systemic inflammation in contributing to poor outcomes after transplantation.     

Effects of intravenous anesthetics on interleukin (IL)-6 and IL-10 production by lipopolysaccharide-stimulated mononuclear cells from healthy volunteers

BACKGROUND: Surgical trauma has been shown to augment the plasma concentrations of proinflammatory cytokines, which are important mediators of host defense mechanisms and the systemic inflammatory response syndrome (SIRS). Recently, it has been shown that certain kinds of surgery provoke not only a proinflammatory response (SIRS) but also a concurrent anti-inflammatory response. The aim of this study was therefore to examine the effects of intravenous anesthetics on the synthesis of interleukin (IL)-6 (a proinflammatory cytokine) and IL-10 (an anti-inflammatory cytokine) by lipopolysaccharide (LPS)-stimulated mononuclear cells from healthy volunteers. METHODS: Peripheral blood mononuclear cells (PBMCs) from 17 healthy volunteers, separated by centrifugation on a Ficoll-Hypaque gradient, were washed and suspended in RPMI containing 10% heat-inactivated fetal calf serum (FCS). After adding RPMI-FCS containing various concentrations of intravenous anesthetics (propofol, thiopental, ketamine and midazolam), the PBMCs were incubated overnight in the presence of a submaximal concentration of LPS. The supernatants were collected and their IL-6 and IL-10 contents were assayed using enzyme-linked immunosorbent assay kits. RESULTS: Propofol inhibited both IL-6 and IL-10 production at 0.5 microg/mL, 5 microg/mL and 50 microg/mL. Conversely, thiopental induced IL-10 production at 2 microg/mL and 20 microg/mL. CONCLUSION: Propofol appears to inhibit both IL-6 and IL-10 production by LPS-stimulated PBMCs in vitro. Further study is required to clarify the mechanism of the suppressive effect of propofol.
