Postoperative Pulmonary Hemodynamics and Systemic Inflammatory Response in Pediatric Patients Undergoing Surgery for Congenital Heart Defects. Mediators Inflamm 2022; 2022:3977585. [PMID: 35075348 PMCID: PMC8783708 DOI: 10.1155/2022/3977585] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2021] [Revised: 12/17/2021] [Accepted: 12/27/2021] [Indexed: 12/15/2022] Open
Abstract
There is scarce information about the relationships between postoperative pulmonary hemodynamics, inflammation, and outcomes in pediatric patients with congenital cardiac communications undergoing surgery. We prospectively studied 40 patients aged 11 (8–17) months (median with interquartile range) with a preoperative mean pulmonary arterial pressure of 48 (34–54) mmHg who were considered to be at risk for postoperative pulmonary hypertension. The immediate postoperative pulmonary/systemic mean arterial pressure ratio (PAP/SAPIPO, mean of first 4 values obtained in the intensive care unit, readings at 2-hour intervals) was correlated directly with PAP/SAP registered in the surgical room just after cardiopulmonary bypass (r = 0.68, p < 0.001). For the entire cohort, circulating levels of 15 inflammatory markers changed after surgery. Compared with patients with PAP/SAPIPO ≤ 0.40 (n = 22), those above this level (n = 18) had increased pre- and postoperative serum levels of granulocyte colony-stimulating factor (p = 0.040), interleukin-1 receptor antagonist (p = 0.020), interleukin-6 (p = 0.003), and interleukin-21 (p = 0.047) (panel for 36 human cytokines) and increased mean platelet volume (p = 0.018). Using logistic regression analysis, a PAP/SAPIPO > 0.40 and a heightened immediate postoperative serum level of macrophage migration inhibitory factor (quartile analysis) were shown to be predictive of significant postoperative cardiopulmonary events (respective hazard ratios with 95% CIs, 5.07 (1.10–23.45), and 3.29 (1.38–7.88)). Thus, the early postoperative behavior of the pulmonary circulation and systemic inflammatory response are closely related and can be used to predict outcomes in this population.

Abstract
Introduction Extracorporeal membrane oxygenation (ECMO) has become a standard technique
over the past few decades in intensive care unit (ICU). Objective A review of pediatric patients who received ECMO support in the pediatric
cardiac ICU was conducted to determine the incidence, risk factors and
causal organisms related to acquired infections and assess the survival
rates of ECMO patients with nosocomial infections. Methods Sixty-six patients who received ECMO support in the pediatric cardiac ICU
between January 2011 and June 2014 were included in the study. Demographic,
echocardiographic, hemodynamic features and surgical procedures were
reviewed. Results Sixty-six patients received a total of 292.5 days of venoarterial ECMO
support. Sixty were postoperative patients. Forty-five patients were weaned
from ECMO support with an ECMO survival rate of 68.2%. The rate of infection
was 116.2/1000 ECMO days. Prolonged ICU stay, duration of ventilation and
ECMO were found associated with development of nosocomial infection and only
the duration of ECMO was an independent risk factor for nosocomial
infections in ECMO patients. Conclusion The correction of the underlying process leading to ECMO support and
shortening the length of ECMO duration together with stricter application of
ECMO indications would improve the infection incidence and hospital
surveillance of the patient group.

Abstract
The aim of this study was to evaluate plasma levels of two mediators with immunosuppressive properties, complement fraction C3a (C3a) and transforming growth factor-β1 (TGF-β1), during extracorporeal circulation. The proliferation index after phytohaemagglutinin (PHA) stimulation of isolated peripheral blood mononuclear cells was also investigated. Sixteen patients undergoing hypothermic (n = 8, group 1) and normothermic (n = 8, group 2) cardiopulmormry bypass (CPB) were enrolled in this study. As a control, we evaluated four patients undergoing thoracovascular operations without CPB. Blood samples were collected before CPB but after anaesthesia, every 30 min during CPB, at the end of CPB and 10 min after protamine administration. Both C3a and TGF-β1 increased significantly during CPB and after protamine administration in the hypothermic as well as the normothermic group. In the latter case the increase of C3a and TGF-β1, although more prominent, was not significantl higher than in the former group. Conversely, the proliferation, index of peripheral mononuclear cells had already decreased 30 min after CPB was started and remained depressed throughout the CPB time. These results suggest a possible role of C3a and TGF-β1 in the immunological changes occurring during extracorporeal circulation.

Abstract
Newer oxygenators with the latest technologies are designed to attenuate the immune response, including lymphopenia, prompted by cardiopulmonary bypass (CPB) in cardiac surgery. We evaluated the effect of CPB, comparing an oxygenator with a venous-arterial shunt and a conventional oxygenator with regard to lymphocyte's early activation and apoptosis induction and its implications in post-CPB lymphopenia. Patients undergoing coronary artery bypass graft surgery with CPB, using either a conventional oxygenator or one with a venous-arterial shunt, had blood samples drawn at anesthetic induction (baseline); the beginning and end of the CPB; and at 6, 12, and 24 hours after surgery. Analysis by flow cytometry was undertaken to assess the expression of lymphocyte surface markers (CD3+, CD25+, CD26+, CD69+) and apoptosis (annexin V). Twenty patients were studied; 10 used a conventional oxygenator, and 10 used an oxygenator with venous-arterial shunt. Postoperative lymphopenia (50% decrease), 35% increased expression of CD69+, and 56% decrease in annexin V were significant comparing baseline to 24 hour value, similarly in both groups. Early activation (expression of CD69+) and degree of apoptosis (expression of annexin V) of lymphocytes after CBP in cardiac surgery was similarly observed in both types of oxygenators. The observed lymphopenia after CPB does not appear to be secondary to apoptosis.

Abstract
This 10-year Medline search of English-language articles describing experimental and clinical studies on chemokines, cardiopulmonary bypass (CPB) and systemic or multiorgan failure revealed that chemokines are significantly involved in the pathogenesis of post-CPB syndrome. The post-CPB inflammatory response depends upon recruitment and activation of inflammatory cells. Leucocyte recruitment is a well-orchestrated process that involves several protein families, including pro-inflammatory cytokines, adhesion molecules and chemokines. Current anti-inflammatory therapies mostly act on the cells that have already been recruited. A more efficient therapy might be the prevention of excessive recruitment of particular leucocyte populations by antagonizing chemokine receptors which might act upstream of the current anti-inflammatory agents. The chemokines, which are a cytokine subfamily of chemotactic cytokines, participate in recognizing, recruiting, removing and repairing inflammation. As chemokines target specific leucocyte subsets, antagonism of a single chemokine ligand or receptor would be expected to have a circumscribed effect, thereby endowing the antagonist with a limited side-effect profile. Chemokines should be considered as possible targets for therapeutic intervention.

Abstract
This study examines the effect of methylprednisolone on cytokine balance and adhesion molecule expression within an isolated cardiopulmonary bypass (CPB) system. This isolated CPB system is an in vitro model which simulates the pro-inflammatory immune response. Whole blood from 10 volunteers was obtained in two equal amounts. Heparin and saline were added to the control group while heparin and methylprednisolone were added to the methylprednisolone group. The blood was added to two identical CPB circuits and bypass commenced by a trained perfusionist. Samples were taken at blood donation (Sample 0), 10 min after the addition of drugs (Sample 1) and after 30, 60 and 90 min of CPB (Samples 2, 3 and 4, respectively). Cytokines interleukin-8 (IL-8), interleukin-10 (IL-10), interleukin-1 receptor antagonist (IL-1ra) and tumour necrosis factor soluble receptor 2 (TNFsr2) and the leucocyte adhesion molecules L-selectin, HLA DR, CD18 and CD11b were determined. IL-8 increased in both groups. This increase was significantly less in the methylprednisolone group. Increases in granulocyte CD11b and CD18 expression were less in the methylprednisolone group than in the control group but did not reach statistical significance. These results indicate that methylprednisolone significantly reduces the production of IL-8 in an isolated CPB system. This effect occurs in the absence of IL-10.

Abstract
STUDY OBJECTIVE To observe changes in the peripheral lymphocyte subpopulations as an index of cellular immunity during neurosurgical procedures. DESIGN Clinical study. SETTING Operating room of a university hospital. PATIENTS 11 patients with early intracranial disease who were scheduled to undergo elective neurosurgery with general anesthesia. Patients in the control group (n = 10) underwent minor surgeries such as ophthalmologic, otorhinolaryngological, or orthopedic surgeries. INTERVENTIONS Blood was sampled before anesthesia induction (t0) for baseline and at 1 hour (t(1)) and 2 hours (t(2)) following surgical incision. MEASUREMENTS Detection and quantification of lymphocyte subpopulations were performed at each time point using single-label and double-label analyses of monoclonal antibodies against lymphocyte membrane surface markers. MAIN RESULTS Significant changes in patients who underwent a neurosurgical procedure included: the percentage of total T cells (CD3+) from 57.54 +/- 3.50% at t(0) to 51.41 +/- 4.26% at t(1) and 46.29 +/- 4.02% at t(2); the percentage of inducer T cells (CD4+, Leu8+) from 27.39 +/- 2.26% at t(0), to 23.26 +/- 2.30% at t(1) and 20.82 +/- 2.70% at t(2); the CD4/CD8 ratio, from 1.78 +/- 0.25% at t(0) to 1.35 +/- 0.12% at t(1) and 1.22 +/- 0.17% at t(2). The percentage of suppressor T cells (CD8+, Leu15+) increased significantly from 10.8 +/- 1.07% at t(0) to 13.64 +/- 1.62% at t(1), and 14.82 +/- 1.24% at t(2). The percentages of the natural killer cell subsets also increased significantly. Control group patients who underwent minor surgeries showed no significant changes. CONCLUSIONS Neurosurgery-induced significant suppression of cellular immunity was demonstrated in peripheral lymphocyte subpopulations, probably from the surgical stress on the central nervous system.

Abstract
OBJECTIVE The influence of open-heart surgery on antigen-specific immunity, also called adaptive immunity, remains to be clarified. We explored the effects of open-heart surgery on adaptive immunity. METHODS In 8 consecutive adult patients undergoing elective cardiac surgery with cardiopulmonary bypass, we measured the T cell-response to purified protein derivative (PPD) antigen perioperatively. We separately measured the proliferation of T cells and the antigen presentation of antigen-presenting cells (APCs) using a cross-reaction system. RESULTS T cell response to PPD antigen was severely impaired by open-heart surgery. Compared to preoperative values, T cell response to PPD antigen fell to 5.7 +/- 4.4% immediately after surgery, 4.5 +/- 3.2% on postoperative day (POD) 1, to 22.4 +/- 24.6% on POD 3 and to 50.1 +/- 34.3% on POD 7. T cell proliferation on POD1 decreased to 29 +/- 26%. APC antigen-presentation on POD 1 also decreased to 31 +/- 36%. CONCLUSIONS Open-heart surgery impaired both T cell proliferation and the antigen-presentation. Such synergistic impairment severely impaired adaptive immunity. This impairment was both severer and longer than we anticipated based on previous studies using the response of T cells to lectin as a marker of cell-mediated immunity.

Abstract
BACKGROUND Surgery involving cardiopulmonary bypass (CPB) is frequently accompanied by a systemic inflammatory response partly triggered by neutrophils and monocyte-macrophages. Certain cytokines that are powerful leukocyte-chemotactic factors have recently been characterized and shown to be important in evoking inflammatory responses: monocyte chemoattractant protein-1 (MCP-1) has monocyte-macrophage chemotactic activity, and regulated-upon-activation normal T-cell expressed and secreted (RANTES) has a potent chemoattractant activity for mononuclear phagocytes. This prospective cohort study investigated possible roles of these chemokines in the inflammatory response to CPB and relationships between the changes in chemokine levels and the clinical course and outcome. METHODS Systemic blood of 16 children undergoing CPB was collected after induction of anesthesia (base line); at 15 minutes after bypass onset; at CPB cessation; and at 1, 2, 4, 8, 12, and 24 hours afterward to measure MCP-1 and RANTES. RESULTS The significant changes of plasma beta chemokine levels following CPB were associated with patient characteristics, operative variables, and postoperative course. Cardiopulmonary bypass of more than 2 hours, longer surgical times, inotropic support, and reoperation were associated with higher MCP-1 levels and lower RANTES levels. CONCLUSIONS Our results suggest a relation between CPB-induced mediators and clinical effects, implying pathogenic roles for chemokines following CPB. These molecules should be considered as possible targets for therapeutic intervention.

Abstract
Cardiac surgery with cardiopulmonary bypass (CPB) leads to a systemic inflammatory response with secretion of cytokines. Alterations in the serum concentrations of cytokines have important prognostic significance. Reports on cytokine release during cardiac surgery with CPB have yielded conflicting results. Haemodilution occurs with the onset of CPB resulting in large fluid shifts during the perioperative course of cardiac procedures. In the present study we compare the perioperative course of serum concentrations of TNF-alpha, IL-1beta, IL-6, IL-10 and sIL-2R with and without correction for haemodilution in patients undergoing coronary artery bypass grafting (CABG) surgery. Twenty male patients undergoing elective CABG surgery with CPB and general anaesthesia using a balanced technique with sufentanil, isoflurane and midazolam were enrolled into the study. Serum levels of TNF-alpha, IL-1beta, IL-6, IL-10 and sIL-2R were measured using commercially available ELISA kits. Simultaneous haematocrit values were obtained at all sample times. Statistical analysis was performed by non-parametric analysis of variance and t-tests for data corrected for haemodilution and data that were not corrected for haemodilution. Adjusted significance level was P < 0.01. Intra-operatively, up to the second post-operative day PCV values were significantly decreased compared with preoperative values. Cytokine measurements not corrected for haemodilution were significantly lower than the corrected values. The perioperative haemodilution and decrease in PCV may lead to an underestimation of the cytokine secretion in post-operative patients. We conclude that cytokine measurements were significantly influenced by the perioperative haemodilution and the subsequent decrease in PCV and may in part account for the varying results reported in the literature regarding cytokine release in patients undergoing CABG surgery.

Abstract
This study investigated whether the lymphocyte count is a useful indicator to assess surgical damage following extracorporeal bypass. In Study 1, to investigate the correlation between extracorporeal circulating time (ECCT) and lymphocyte counts, 40 elective CABG patients were studied retrospectively. The lymphocyte recovery ratio (LRR), which represented the actual lymphocyte count divided by the preoperative lymphocyte count, was determined preoperatively, and on postoperative day (POD) 1, POD 3, and POD 5. In Study 2, the correlation between the interleukin-8 (IL-8) level and LRR was examined prospectively in elective CABG patients (n = 20). We measured the LRR and serum IL-8 levels preoperatively and during extracorporeal circulation (ECC) at 5 min, at the end of ECC, and 1, 3, and 12 h following ECC termination. Study 1 showed that the LRR decreased until POD 1 and gradually increased thereafter. The LRR had a negative correlation with the ECCT. In Study 2, the IL-8 level demonstrated a time course opposite to that of the LRR; it increased until 3 h after ECC termination and declined thereafter. There was a significant negative correlation between the LRR on POD 3 and the IL-8 level at 3 h after ECC termination. In summary, long-term ECC induced significant and prolonged lymphocytopenia. The LRR had a negative correlation with IL-8. These results indicated that the LRR may represent the degree of surgical stress following ECC; therefore, the counting of lymphocytes can be a quite useful bedside monitor to assess surgical damage and prognosis.

Abstract
In a patient with severe ischemic heart disease and advanced human immunodeficiency virus (HIV) infection, vigorous perioperative treatment with anti-retroviral agents was given and coronary artery bypass surgery using cardiopulmonary bypass was successfully performed. This strategy could become the standard for patients with cardiovascular disease and advanced HIV infection. The following aspects of this case require further investigation: (1) lack of a reactive increase in the neutrophil count, (2) transient extreme reduction of lymphocytes, and (3) a relative decrease in the CD8+ cell ratio.

Abstract
OBJECTIVE Depressive effects of cardiopulmonary bypass on cell-mediated immune responses may lead to postoperative infectious complications. We previously reported that cimetidine reduced postbypass depression of the cytotoxic activity of natural killer cells. This study evaluated cimetidine as an agent to preserve cellular immunity after cardiac operations. METHODS In a prospective randomized study, 20 patients were divided into two groups of equal size. Cimetidine-group patients received 400 mg of cimetidine intravenously before bypass and a 33 mg/hr intravenous infusion of cimetidine after the operation, continuing until the fifth postoperative day. Control-group patients received conventional perioperative therapy. Lymphocyte subsets, natural killer cell activity, percentage of CD56+CD16+ (percentage of natural killer cells), and percentage of CD11b+CD8+ (percentage of suppressor T lymphocytes) were measured perioperatively. RESULTS Although temporary postoperative reductions in percentages of CD3+, CD4+, and CD56+CD16+ cells were observed in both groups, CD8+ percentages on postoperative day 1 and CD11b+CD8+ percentages on postoperative days 1 and 3 in the cimetidine group were significantly lower compared with those in the control group (p = 0.01,p = 0.004, andp = 0.02, respectively). Temporary postoperative reduction of natural killer cell activity was also observed in both groups, but the natural killer cell activity on postoperative day 1 in the cimetidine group (17.1%) was significantly higher (p = 0.02) than that in the control group (8.20%). CONCLUSIONS Cimetidine counteracts depressive effects of cardiopulmonary bypass on cell-mediated immunity and may possibly reduce postoperative susceptibility to infection.

Abstract
Complications of cardiopulmonary bypass (CPB) may be associated with either immune suppression or immune activation, but the specific effects of CPB on many lymphocyte and monocyte subsets are unclear. In addition, the increasing age of patients undergoing cardiac surgery raises the possibility of even greater effects on the immune system in elderly patients. We measured immunophenotypic alterations of circulating lymphocytes and monocytes after CPB in male and female cardiac surgery patients who were either younger than 60 or older than 75 years of age. The total lymphocyte counts in all patients decreased postoperatively; older patients had significantly lower counts at all time points. The absolute decline was greatest among T cells and particularly CD4+ T cells, which reached an average nadir of 251 cells/microl on postoperative day 1 in the older patients. The percentages of CD8+, CD4+CD45RA+, and CD4+CD45RO+ T cells did not change significantly, whereas the percentages of B cells and natural killer cells increased. Both T and B lymphocytes and monocytes showed evidence of activation, with increased percentages of CD3+HLADr+, CD3+IL2R+, and CD19+CD23+ lymphocytes and increased expression of CD11b on monocytes. By contrast, expression of class II major histocompatibility antigen (HLADr) monocytes decreased significantly. We conclude that CPB produces a profound alteration in the pool of circulating lymphocytes and monocytes, evidenced by decreased numbers of lymphocyte subsets including CD4+ cells and decreased expression of monocyte surface membrane proteins important for antigen presentation; CPB also activates a variety of specific circulating mononuclear cell subsets. Older patients showed patterns of lymphocyte and monocyte activation comparable to those of younger patients; however, they had consistently lower lymphocyte numbers and a trend toward decreased monocyte HLADr expression, potentially placing them at greater risk for infectious complications. Gender had no effect.

Abstract
The role of surgery in the natural history of HIV disease is in evolution. A review was conducted of 2980 CABG operations taking place between January 1992 and January 1996 at St. Vincents Hospital; four of these patients were known to be HIV-positive prior to the operation. Preoperative work-up, operative course, and postoperative events were largely unremarkable. Only 1 of the 4 patients required rehospitalization within 30 days. Follow-up averaged 28 months (range 7-49 months). Three of four patients were in NYHA Class II or better at follow-up. Other reviews of CABG performed on HIV+ patients also indicate that, although CPB can be linked with immune suppression, there is no conclusive evidence of the acceleration of HIV into AIDS associated with CPB. In conclusion, due to the lack of controlled trials and large patient reviews, no firm recommendations about the effect of CPB on immunocompromized patients can be generated.

Abstract
BACKGROUND A growing body of evidence relates the release during cardiopulmonary bypass (CPB) of proinflammatory cytokines, such as tumor necrosis factor-alpha, interleukin (IL)-6, and IL-8, to the postoperative systemic inflammatory response syndrome. Antiinflammatory cytokines, such as IL-10, however, may also play an important role in limiting these complications. METHODS The English-language literature was reviewed. Emphasis was placed on cytokine responses during clinical CPB for cardiac operations and, in particular, for heart and heart-lung transplantation. RESULTS The recent data indicate that (1) although cytokine release can be triggered by many factors during CPB, ischemia-reperfusion may play the most important role; (2) the levels of tumor necrosis factor-alpha, IL-6, and IL-8 are correlated with the duration of cardiac ischemia and the myocardium is a major source of these three cytokines during CPB; (3) IL-10 levels are correlated with the duration of CPB and the liver is a major source of IL-10 during CPB; and (4) steroid pretreatment is an effective intervention to inhibit the release of proinflammatory cytokines and enhance IL-10 production. CONCLUSIONS The improved knowledge of cytokine responses to CPB may help to develop interventions aimed at reducing postoperative morbidity and mortality.

Abstract
We compared the effects of a centrifugal pump with those of a roller pump on immune responses in 26 coronary artery bypass surgery patients during cardiopulmonary bypass (CPB). The patients were randomly allocated into a (Biomedicus) centrifugal pump group and a (Stöckert) twin roller pump group. Leucocyte and differential counts; percentages of lymphocyte subpopulations (CD3-, CD4-, CD8-, CD16-, CD20- and CD25-positive lymphocytes) and monocytes (CD14); phytohaemagglutinin-, concanavalin A-, and pokeweed mitogen-induced and unstimulated proliferation of separated lymphocytes; unstimulated and pokeweed mitogen-stimulated production of IgG, IgM, or IgA; and plasma fibronectin, C-reactive protein and serum albumin concentrations were measured preoperatively, immediately before CPB, immediately before aortic declamping and on the first postoperative morning. Significant changes were seen in these variables, but no differences occurred between the groups.

Abstract
To evaluate the effect of cardiopulmonary bypass on immunological function, we measured interleukin-6 (IL-6) and tumor necrosis factor (TNF) in 12 patients undergoing cardiac surgery during and after cardiopulmonary bypass, and in 10 patients with pancreatoduodenectomy. Plasma IL-6 levels were determined using the Human Interleukin 6 ELISA Kit, and TNF levels were determined using a highly sensitive sandwich enzyme immunoassay. In patients with cardiac surgery, plasma levels of IL-6 and TNF increased during cardiopulmonary bypass, and in patients with pancreatoduodenectomy, IL-6 and TNF levels significantly increased at the end of intraabdominal manipulation. These results suggest that endotoxin may have activated the immune system and stimulated cytokine production after pancreatoduodenectomy and during bypass.

Abstract
Little data exist on the type of infections patients acquire during extracorporeal life support. Through a retrospective analysis of 109 patients who underwent 115 episodes of venoarterial extracorporeal life support, it was determined that nosocomial infections developed in 18 patients (16%). Patients with nosocomial infections were supported for longer periods of time (230 versus 140 hours; P < .05) and were more likely to have an open chest (P = .02) than those who did not have infectious complications. Blood-borne infections occurred most often while patients were cannulated for extracorporeal life support, with urinary tract and wound infections more commonly occurring after decannulation. Fungal organisms were isolated in 50% of nosocomial infections. Patients with blood or wound fungal infections had a higher case-fatality rate than those patients with bacterial complications (P = .03). Because it is unlikely that the duration of extracorporeal life support can be shortened significantly, the authors recommend an increased level of awareness of nosocomial infections in patients on prolonged extracorporeal life support. Further research is needed to assess the effects of antifungal prophylaxis or immune modulation to prevent nosocomial infections.

Abstract
T cell subsets and immunoglobulin (Ig) were observed sequentially with the OKT monoclonal antibodies rosette test and the rate scattering turbidimetry in 13 patients who underwent open heart surgery under cardiopulmonary bypass (CPB) for rheumatic heart diseases (RHD) and congenital heart diseases (CHD), before and after operation. Compared with preoperative values, in the early period after CPB, T helper cells, T helper cells to T suppressor cells ratio and IgG decreased significantly; whereas T suppressor cells increased, in RHD and CHD. The T cell subsets returned to the preoperative levels two weeks after CPB in RHD and CHD. The IgG came back to the preoperative levels two weeks after CPB in RHD and only one week after CPB in CHD.

Abstract
Erythropoietin is the primary growth factor for red blood cells. A glycoprotein hormone synthesized by the kidneys, erythropoietin serves to increase red blood cell production in response to tissue hypoxia. It exerts its effect by increasing the numbers of erythroid progenitor cells in the bone marrow, and by increasing the rate at which their development is accomplished. With the introduction of recombinant erythropoietin in 1987, an important pharmacological agent became available for the manipulation of erythropoiesis. While used primarily for the treatment of the anemia of renal failure, recombinant erythropoietin has also shown usefulness in treating other types of anemias in which the endogenous erythropoietin response is insufficient. Perioperative use of the drug grew as a natural extension of this, and erythropoietin has been applied to correct preoperative anemia, augment autologous blood donation, and improve postoperative red cell recovery. Analysis of these perioperative clinical studies reveals success in these areas, but it also reveals that closer attention to the physiology of the natural response, and to the pharmacology of the recombinant product, might significantly improve results. Such an improvement in efficacy is both desirable and necessary when use of the drug is viewed in the setting of today's changing health care environment. By optimizing dosing schedules and targeting the drug to those most at risk for red cell transfusion, recombinant erythropoietin will likely become an important tool in efforts to achieve the elusive goal of bloodless cardiac surgery.

Abstract
High serum level of immunoreactive but not biologically active IL-2 was detected 1 day after surgery in patients undergoing major operation (abdominal, open-heart), in proportion to the tissue injury caused by surgical trauma. IL-2 values were highest in those patients who underwent open-heart surgery and received blood transfusions. In all patients they declined in the third and fourth post-operative days. Elevated serum levels of soluble IL-2 receptors (sIL-2R) were already present 1 day after operation, and peaked in the third and fifth post-operative days after mitogen triggering. Blood lymphocytes derived from operated patients secreted reduced amounts of both IL-2 and sIL-2R compared with control lymphocytes. The extent and duration of this reduction were also proportional to the tissue trauma and were affected by blood transfusions. Based on these data we suggest that early post-operative systemic immunological activation (appearance of IL-2 in the serum) is followed by elevation of sIL-2R, which then interferes with IL-2-dependent immunity. Blood lymphocytes are probably not involved in the post-operative immunological activation. The trigger for and the site of IL-2/sIL-2R synthesis are not yet clear.

Abstract
To prove the hypothesis that cardiopulmonary bypass may accelerate the development of acquired immunodeficiency syndrome (AIDS) in the human immunodeficiency virus carrier, the clinical course of 40 patients positive for human immunodeficiency virus who underwent cardiac operations between 1986 and 1992 was analyzed, especially in regard to the progression to AIDS. Mean age was 30 years (range, 19 to 61 years). Thirty-four patients (85%) were intravenous drug abusers; in 4 (10%) transmission of infection was sexual, and in 2 (5%) it was through a contaminated blood transfusion. Valve procedures were performed in 38 patients (95%), mostly for endocarditis in drug addicts. Hospital mortality was 20% (8 patients). The 32 survivors have been followed up a mean of 21 months (range, 4 months to 6 years). Four patients (12.5%) experienced progression to AIDS during the follow-up period. Actuarial progression to AIDS is 5% (+/- 5%) at 1 year, 20% (+/- 10%) at 2 years, and 40% (+/- 19%) at 5 years. There have been 8 late deaths (5 due to recurrent endocarditis, 2 due to AIDS, and 1 due to overdose). Actuarial survival is 79% (+/- 8%) at 1 year, 60% (+/- 11%) at 2 years, and 48% (+/- 14%) at 5 years. The results indicate that progression to AIDS in the patient positive for human immunodeficiency virus is not accelerated by the use of cardiopulmonary bypass. The poor prognosis in these patients is mainly related to the particular pathological conditions that often affect the drug addict population.

Abstract
To investigate whether cell-mediated immunity responses are suppressed or activated by the effect of cardiopulmonary bypass (CPB), we studied peripheral blood lymphocyte subsets and antibody-dependent cell-mediated cytotoxicity in 52 adult patients who had undergone open heart operations. Lymphocyte function also was studied with regard to mixed lymphocyte reaction, which indicates the amount of DNA synthesis of lymphocytes, and natural killer (NK) cytotoxicity, which represents the killing activity of NK cells on the tumor cells (K-562), in 11 patients. The total T lymphocyte (OKT3+ and OKT11+) number showed no significant change during CPB. Suppressor/cytotoxic T cell (OKT8+) and NK cell (Leu7+ and Leu11+) numbers were found to be remarkably increased. However, helper/inducer T cell (OKT4+) and B cell (Leu12+) numbers were decreased during CPB. Antibody-dependent cell-mediated cytotoxicity was elevated during CPB. All of these changes were almost returned to the preoperative levels by the seventh day after operation. Mixed lymphocyte reaction and NK cytotoxicity were also activated during CPB. The results show that heart operations in which cardiopulmonary bypass is used are associated with activation of cytotoxic cell-mediated immunity.

Abstract
Interleukin-6 (IL-6) and alpha-melanocyte-stimulating hormone (alpha MSH) are important modulators of the immunologic response to tissue injury and antigenic challenge. Serial changes in the plasma concentrations of these two peptides were measured in 12 patients undergoing heart transplantation. Tissue concentrations of IL-6 in atrial samples from both donor and recipient hearts were also compared. Plasma IL-6 concentration remained stable prior to cardiopulmonary bypass (CPB), initially decreased with the onset of CPB, and then increased significantly over control values at the end of CPB (180 +/- 40 v 53 +/- 60 pg/mL). Plasma IL-6 remained elevated for at least 60 minutes after CPB, and then it returned to control values by 24 hours postoperatively (67 +/- 9 pg/mL). Examination of IL-6 changes after CPB in 10 additional patients undergoing nontransplant cardiac surgery with CPB revealed a similar elevation in IL-6 at 60 minutes after CPB (290 +/- 76 pg/mL). However, IL-6 in the nontransplant group remained significantly elevated at 24 hours (138 +/- 42 pg/mL). These combined results suggest that CPB causes a marked increase in IL-6, and that implantation of a new heart in transplant patients does not augment this increase. The return of IL-6 to control values by 24 hours in the patients who have had transplants suggests that immunosuppression has an appreciable effect on IL-6 at this time. In contrast to IL-6, plasma alpha MSH never increased above control values.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Plasma levels of biologically active IL-1, tumour necrosis factor (TNF) and IL-6 were measured before, during and after coronary artery bypass graftings (CABG) (n = 9) and cholecystectomy (CHO, n = 9), and in normal controls (nine healthy volunteers). Mean pre-operative IL-1 concentration in four of the nine CABG patients was 0.452 + 0.03 ng/ml, significantly (P less than 0.001) higher than that of the other five (0.045 +/- 0.009 ng/ml), CHO patients (0.035 +/- 0.005 ng/ml) and controls (0.029 +/- 0.008 ng/ml). Three of the four patients with high pre-operative IL-1 had functional capacity IV, while the other five had functional capacity IIa or IIb. Slight IL-1 elevation after anaesthesia, followed by reduction after initiation of bypass, elevation on completion of surgery and reduction to basal levels after 7 days was found in patients undergoing CABG. Mean basal TNF levels of CABG and CHO patients did not differ, but were higher than those of controls (2.85 +/- 0.5 ng/ml for CABG, 2.05 +/- 0.06 ng/ml for CHO, 0.72 +/- 0.07 ng/ml for normals, P less than 0.001). A unique kinetics of release during CABG was observed also for TNF. Mean pre-operative IL-6 levels were normal (50 +/- 3 ng/ml for CABG, 50 +/- 0.5 ng/ml for CHO and 65 +/- 10 ng/ml for controls). Gradual elevation to a mean peak of 725 +/- 100 ng/ml on completion of CABG was observed as compared with 275 +/- 50 ng/ml in CHO (P less than 0.01). On the seventh post-operative day mean IL-6 levels returned to normal. Two patients with post-operative low-grade fever (38 degrees C) had high, late cytokine levels. One of these two patients had leucocytosis, sterile discharge from the operative wound and was diagnosed as suffering from the Dressler syndrome. In this study elevated cytokine values and unique kinetics of release into the serum were found in patients undergoing CABG.

Abstract
Pneumocystis carinii pneumonia (PCP) occurs frequently in individuals infected with the HIV virus. Malignancy, immunosuppressive drugs, and congenital immune deficiency may be associated with PCP. We describe a patient with stage 1 testicular carcinoma who developed hypoxemic respiratory failure two days after retroperitoneal lymph node dissection. Pneumocystis carinii organisms were demonstrated by catheter lavage samples and confirmed on bronchoalveolar lavage. Testing for HIV antibody by ELISA and the Western blot test were negative; HIV viral culture and polymerase chain reaction were also negative. Pneumocystis carinii pneumonia is unusual in localized surgically cured malignancies without obvious immunodeficiency and, to our knowledge, has not been described as a cause of postoperative respiratory failure.

Abstract
Extracorporeal cardiopulmonary bypass (CPB) has been associated with a wide variety of immunological derangements, including a transient postoperative impairment of lymphocyte function. We examined changes in phenotypic and nonspecific cytotoxicity of peripheral blood mononuclear cells after extracorporeal CPB. The peripheral blood samples obtained from 10 patients were subjected to natural killer and cytotoxic T lymphocyte activity assay before and at intervals after CPB. Phenotypic analysis of peripheral blood lymphocytes was performed in 5 patients before and immediately after CPB. We observed a significant increase in peripheral blood CD8+ cells (cytotoxic/suppressor T lymphocytes) (16.1% +/- 2.5% versus 22.5% +/- 2.1%; p less than .005) and a decrease in CD4+ cells (helper/inducer T lymphocytes) (46.1% +/- 3.5% versus 36.1% +/- 3.5%; p less than 0.02) immediately after extracorporeal circulation. The CD8/CD4 ratio in peripheral blood was significantly increased immediately after bypass (0.53 versus 0.80; p less than 0.001). No significant changes in percentages of other leukocyte subsets in peripheral blood were noted. The activity of cytotoxic T lymphocytes and natural killer cells in peripheral blood was impaired on postoperative days 1 and 3 but was restored to preoperative values by removal of mononuclear phagocytes from these cells. The decrease in natural killer cell and cytotoxic T lymphocyte activity in peripheral blood may signify a temporary impairment of the effector arm of the cell-mediated immunity in the post-operative period. The observed changes in peripheral blood phenotype and function may be involved in early organ injury and infectious complications after CPB.

Abstract
Alterations have been found to occur in every component of immune response during anaesthesia and surgery. These alterations represent the body's general physiological responses and are mainly dependent on the extent of surgery, as well as other factors such as the patient's age and health status, medication and blood transfusion. Anaesthetic and operative complications have profound effects on these responses. Basically, the immune response to anaesthesia and surgery is a beneficial reaction, needed in local host defences and wound healing and in preventing the body from making autoantibodies against its own tissues. The responses may, however, contribute to the development of postoperative infections and spread of malignant disease. During uncomplicated conventional surgery, the immune response usually passes clinically unnoticed without any harmful effects. Absent responses and excessively high responses, on the other hand, harm the patient. Our understanding of immunological phenomena and our possibilities of controlling mediator activation are now lagging behind the technical advances made in operative treatment. If we want to decrease operative morbidity and mortality to below their present levels, more attention should be directed to immune responses to major surgery, injuries and operative complications with massive mediator release which place the surgical patient at risk. Experimental evidence suggests that results of treatment in injured and operated patients can in the future be improved by controlling immune responses and their mediator systems. Our current level of knowledge of immune responses is already helping us to avoid many immune-mediated complications. However, routine interference with these responses is not indicated.

Abstract
The expression of class II major histocompatibility complex (MHC) molecules on monocytes and the relative proportion of immunoregulatory lymphocyte subpopulations were studied from the blood of eight patients undergoing a cardiac operation. The aim of the study was to reveal mechanisms responsible for depression of cellular immunity and B-lymphocyte activation associated with open-heart surgery. A decreased staining of HLA-DR and even more of HLA-DQ class II MHC molecules was found on the monocyte surface in samples taken 2 and 7 days after operation when compared to preoperative values. The relative proportion of monocytes in mononuclear cells increased after surgery, but within lymphocyte subpopulations only a decrease in total T cells and an increased number of activated (HLA-DR positive) T cells were found, whereas the rations between various T cells subsets remained relatively stable.

Abstract
We reported previously in a randomized double-blinded study in 20 postoperative coronary bypass patients that hypertonic saline (1.8% NaCl, HS) provides early hemodynamic benefits, increased osmolality and net negative fluid balance compared to 0.9% NaCl (NS). To investigate the effects of HS on the hormonal response to injury, we measured ACTH, cortisol, angiotensin II (AII), aldosterone, vasopressin (AVP), and atrial natriuretic factor (ANF) in these patients. ACTH and cortisol concentrations increased in the NS group but were suppressed in the HS group (p less than 0.05). Aldosterone increased in NS patients, but was suppressed in HS patients (HS: delta Aldosterone 13.0 +/- 3.0 vs. NS: delta Aldosterone 26.0 +/- 7.0 ng/dl, p less than 0.05). The AII response was suppressed at six and eight hours (p less than 0.05) in patients receiving HS but did not change in patients receiving NS. ANF did not change significantly for either group. The significant increases in AVP were similar in both groups (p less than 0.05), but correlated with increases in osmolality only in the NS group (r = 0.8, p less than 0.009). Other than AVP, HS suppressed the responses of some of the hormones that normally increase in response to injury, relative to NS. Attenuation of the neuroendocrine response and other previously reported effects of HS suggest that HS may be an efficacious solution for resuscitation in the postoperative and postinjury period.
