BACKGROUND: Patients who undergo major surgery for cancer are at high risk of postoperative infection. Postoperative immunosuppression may be due to dysregulation of cytokine production. The aim of this study was to investigate the association between changes in serum proinflammatory and anti-inflammatory cytokine concentrations and postoperative septic complications after major surgery. METHODS: Serial blood samples were collected from 30 consecutive patients for determination of serum cytokine levels. Healthy volunteers were used as the control group. RESULTS: Eleven patients developed no complications (group 1), 14 developed sepsis or severe sepsis (group 2), and five developed septic shock (group 3). On day 1 the patients in groups 2 and 3 had significantly higher levels of interleukin (IL) 6 than those in group 1. IL-6 levels remained high until day 5. Tumour necrosis factor (TNF), IL-1, interferon (IFN) gamma and IL-12 levels were not affected by surgical trauma or by the occurrence of septic complications. After operation the circulating IL-1 receptor antagonist (IL-1ra) concentration was increased in all groups, but patients in group 3 had significantly higher levels of IL-1ra than those in group 1. IL-1ra levels correlated with IL-6 levels. The pattern of IL-10 levels was similar to that of IL-1ra levels. CONCLUSION: Serum concentrations of proinflammatory cytokines (TNF, IL-1, IFN-gamma and IL-12) were not affected by operation or the occurrence of septic complications. The postoperative increase in IL-6 concentration was associated with septic morbidity, while raised IL-1ra concentration was associated with postoperative septic shock. 相似文献

自体血液回输对脊柱手术患者术后IL-6、IFN-γ和TNF-α的影响 总被引:1,自引:0,他引:1
目的观察同种异体输血和自体血液回输对脊柱手术患者术后免疫反应的影响。方法择期行脊柱手术的患者44例,按手术日奇偶数分为2组,自体组术中仅输注自体洗涤红细胞(22例),异体组术中仅输注异体悬浮红细胞(22例),分别测定2组术前、术后1天和术后7天血清中白细胞介素6(IL-6)、干扰素γ(IFN-γ)和肿瘤坏死因子α(TNF—α)的水平。结果与术前相比,自体组术后1天、7天血清IFN-γ和IL-6均增高,IL-6升高尤为显著,明显高于异体组,2组间差异有显著性(P〈0.01)。2组术后的TNF—α水平在各个时间点都没有明显变化。结论与同种异体输血相比,在脊柱手术中采用自体血液回输对术后患者血清中TNF-α的影响不明显,但可以明显提高IFN-γ和IL-6的水平。自体血液回输对术后免疫细胞因子的抑制作用远小于异体输血,能够保护甚至增强脊柱手术患者术后的细胞免疫功能。 相似文献

INTRODUCTION: To obtain better insight into the kinetics of hepatic growth factors following partial hepatectomy for living related liver donation, we investigated the postoperative changes in serum levels of hepatocyte growth factor (HGF), epidermal growth factor (EGF), vascular epidermal growth factor (VEGF), and transforming growth factor-alpha (TGF-alpha). PATIENTS AND METHODS: Eighteen healthy donors undergoing right hepatectomy for living related donation were enrolled in this study. Serum levels of HGF, EGF, VEGF, and TGF-alpha were measured using enzyme-linked immunosorbent assay kits before surgery, at 2 hours after resection, and daily during 5 days postoperatively. RESULTS: Mean preoperative HGF serum levels in healthy adults were 778 +/- 64 pg/mL. Within 2 hours after operation, they significantly increased to 9608 +/- 3111 pg/mL afterward decreasing to 2726 +/- 241 at day 1 and 2283 +/- 250 pg/mL at day 2. Hereafter HGF serum levels stabilized at increased levels until day 5 (2109 +/- 138, 2047 +/- 219, 2283 +/- 336 pg/mL, respectively). At all time points, the differences between pre- and postoperative HGF levels were significant (P < .01). In contrast, VEGF and EGF serum levels showed no significant differences between pre- and postoperative levels at all time points. TGF-alpha was not detected using a commercially available test with a detection limit of 10 ng/mL, suggesting only low TGF-alpha serum levels following liver resection. CONCLUSION: Significantly increased HGF serum levels after hepatectomy demonstrate its crucial role among the other investigated growth factors in regeneration of the remnant liver tissue during the early period after the operation. 相似文献

Acute focal bacterial nephritis (AFBN) is a localized, interstitial bacterial infection of the renal parenchyma. In this study, we measured the serum levels of several cytokines in patients with AFBN. A total of 11 children were enrolled in the study and classified into two groups of patients: an AFBN group and a control group. There was no significant difference in the serum levels of interleukin (IL)-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12, IL-17, granulocyte-colony stimulating factor, or tumor necrosis factor-α among the patients in the two groups. However, the serum levels of interferon-γ among the patients in the AFBN group were significantly higher than those among the patients in the control group. The current results suggest that the bacterial kidney infection in the AFBN group is localized and that interferon-γ may be produced locally in response to the infection. 相似文献

Transarterial chemoembolization (TACE) is one of the standard therapies for bridging patients with hepatocellular carcinoma (HCC) to transplantation. This study was designed to determine which features on pre- and post-TACE imaging are associated with tumor necrosis in pathological specimens. Records of 105 patients with 132 HCC lesions who underwent liver transplantation after TACE were retrospectively reviewed. In 70% of the nodules, >90% necrosis was achieved. The development of >90% lesion necrosis upon pathological analysis was associated with avid lesion enhancement (P = 0.03) and the presence of a feeding vessel larger than 0.9 mm in diameter on the pre-TACE visceral angiogram (P = 0.01). Near-complete lesion necrosis was also associated with an extensive accumulation of ethiodized oil within a lesion during TACE administration (P = 0.04). On post-TACE computed tomography imaging, a lack of residual contrast enhancement (P < 0.0001), a decrease in the lesion size (P = 0.04), a high lesion density due to an accumulation of ethiodized oil (P = 0.03), and a diffuse distribution of ethiodized oil throughout the lesion (P = 0.0001) were also correlated with near-complete lesion necrosis upon pathological analysis. In conclusion, this study found multiple pre- and post-TACE imaging characteristics of HCC that were associated with near-complete tumor necrosis upon histopathological analysis after TACE. These findings may help to guide the selection of an optimal treatment strategy for bridging patients with HCC to liver transplantation. 相似文献

One of the major issues in contemporary kidney transplantation is prevention of acute allograft rejection episodes (AREs). Cytokines are crucial mediators of immune reactions leading to AREs. We correlated serum Th1/Th2 cytokine concentrations with AREs. The project included 44 patients undergoing kidney transplantation. During the 3-month period following the transplantation, ARE was diagnosed in 11 patients. Serum samples collected 1 day before and 2, 7, 14, and 30 days after transplantation were tested for interleukin (IL)-2, IL-4, IL-5, IL-10, interferon (IFN)-γ, tumor necrosis factor (TNF)-α concentrations using flow cytometry. Nonrejection (NONAR) and rejection (ARE) groups of patients did not show significant differences in baseline demographic characteristics. We observed that higher pretransplantation serum levels of IFN-γ (P = .000003) and IL-10 (P = .000001) were associated with AREs. Our analysis also showed slightly higher IL-4 serum levels among NONAR patients up to 7 days posttransplantation, followed by a drop in concentrations in NONAR patients. In contrast, there was a continuous increase among ARE patients. No significant differences were observed in plasma levels of IL-2, IL-5, IL-10, or TNF-α between the two groups. Higher pretransplantation levels of IFN-γ and IL-10 observed in ARE patients indicated ongoing nondetected, probably nonspecific, inflammatory processes able to intensify an immune response directed against the transplanted organ leading to its acute rejection. Higher levels of IL-4 prior to and shortly after transplantation may have protective effects on graft survival. However, a prolonged, increased production of IL-4 after transplantation can also contribute to AREs. 相似文献

Objectives: This study estimated plasma levels of interleukin IL-1β, IL-6, tumour necrosis factor-α (TNF-α), interferon-γ (INF-γ) in chronic kidney disease (CKD) patients with a single odontogenic pathology. Material and methods: Forty-nine selected adult CKD patients with single odontogenic pathology based on clinical and X-ray examination: patients after proper root canal treatment, without periapical lesions (n?=?12), with pulp necrosis (n?=?7), with asymptomatic periapical lesions (n?=?22), with periodontal disease (n?=?8), and 14 with healthy teeth were enrolled. Patients with coexisting different dental pathologies and the evidence of other infection were excluded. In all patients plasma concentrations of CRP, IL-1β, IL-6, TNF-α, and INF-γ were measured. Results: Patients with periodontitis were characterized by increased concentrations of IL-6 and TNF-α. Those with pulp necrosis had significantly more frequently serum CRP level over 2?mg/L and presented significantly elevated IL-6, but decreased TNF-α concentration than in the subjects with healthy teeth. In patients with periapical lesions and patients after root canal therapy, the concentrations of cytokines did not indicate for the systemic inflammation. Conclusions: Periodontitis and pulp necrosis are important sources of systemic microinflammation in CKD patients. Plasma concentrations of IL-6 and TNF-α appear to be more sensitive markers of odontogenic inflammation in CKD patients than CRP. 相似文献
