Role of serum interleukin-18 as a prognostic factor in patients with hepatocellular carcinoma

AIM:To determine whether serum interleukin-18 (IL-18) levels correlated with clinicopathologic features and prognosis in patients with hepatocellular carcinoma (HCC). METHODS:Serum IL-18,IL-6 and IL-12 levels were measured by enzyme-linked immunosorbent assay (ELISA) from 70 patients with HCC and 10 healthy controls. RESULTS:Serum IL-18,IL-6 and IL-12 levels of patients with HCC were significantly higher that those of the controls. The levels of IL-18 correlated significantly with the presence of venous invasion and advanced tumor stages classified by Okuda's criteria. Patients with high serum IL-18 levels (≥ 105 pg/mL) had a poorer survival than those with low serum IL-18 levels (< 105 pg/mL) (4 and 11 mo,respectively,P = 0.015). Multivariate analyses showed that serum IL-18 level,but not IL-6 and IL-12 levels,was a significant and independent prognostic factor of survival. CONCLUSION:These findings demonstrate that serum IL-8 may a useful biological marker of tumor invasiveness and an independent prognostic factor of survival for patients with HCC. Thus,the detailed mechanisms of IL-18 involving in tumor progression should be further investigated.

SERUM INTERLEUKIN-18 LEVEL AS A PROGNOSTIC MARKER IN PATIENTS WITH COLORECTAL CARCINOMA

Interleukin-18(IL-18) is a cytokine with many functions. This study was to investigate the serum levels of IL-18 and their clinical significance in patients with colore3ctaql carcinomas. Methods: Peripheral blood samples were obtained from 106 patients with colorectal carcinoma and 60 volunteers. The serum IL-18 levels were determined in each sample with an enzyme-linked immunosorbent assay (ELISA). Results: In patients before 1997, the mean IL-18 level was 338.46 pg/ml; in patients after 1997, the mean IL-18 level was 328.85 pg/ml, there is no evidence of loss of IL-18 immunoreactivity after prolonged storage at -80℃. The mean serum IL-18 level in 106 patients with colorectal carcinoma was significantly higher compared with the 60 healthy volunteers (P<0.05). Although the IL-18 level in patients with stage I did not differ from controls, the serum IL-18 levels of patients with stage II, stage III and stage IV disease were significantly higher compared with healthy control (P<0.05). The mean serum IL-18 level of patients with stage III disease, while the difference between patients with stage II and stage IV was not statistically significant (P>0.05). The survival rate of patients with IL-18 levels ≥346 pg/ml (n=47 patients) was significantly worse compared with patients who had IL-18 levels <346 pg/ml(n=57 patients). The 5-year-survival rates were 5.3% and 18.6%, respectively. Multivariate analysis using a Cox proportional hazards model identified the serum IL-18 level as an independent prognostic factor for survival Conclusion: The serum IL-18 level has a significant correlation with survival curve. The serum IL-18 level may represent a significant postoperative prognostic determinant in patients with colorectal carcinoma.

Breast cancer in schizophrenia could be interleukin-33-mediated

Recent epidemiological and genetic studies have revealed an interconnection between schizophrenia and breast cancer.The mutual underlying pathophysiological mechanisms may be immunologically driven.A new cluster of molecules called alarmins may be involved in sterile brain inflammation,and we have already reported the potential impact of interleukin-33(IL-33)on positive symptoms onset and the role of its soluble trans-membranes full length receptor(sST2)on amelioration of negative symptoms in schizophrenia genesis.Furthermore,these molecules have already been shown to be involved in breast cancer etiopathogenesis.In this review article,we aim to describe the IL-33/suppressor of tumorigenicity 2(ST2)axis as a crossroad in schizophreniabreast cancer comorbidity.Considering that raloxifene could be tissue-specific and improve cognition and that tamoxifen resistance in breast carcinoma could be improved by strategies targeting IL-33,these selective estrogen receptor modulators could be useful in complementary treatment.These observations could guide further somatic,as well as psychiatric therapeutical protocols by incorporating what is known about immunity in schizophrenia.

Links between donor macrosteatosis,interleukin-33 and complement after liver transplantation

BACKGROUND As prevalence of nonalcoholic fatty liver disease increases in the population,livers with steatosis will continue to infiltrate the donor pool.Safe utilization of these extended criteria grafts is paramount given the increased risk associated with their use in transplantation.Prognostic factors that can predict liver dysfunction immediately after transplantation with macrosteatotic grafts are lacking.AIM To understand the relationship between interleukin-33(IL-33)and complement in recipients immediately following liver reperfusion as a marker of liver dysfunction.METHODS Cohort consisted of patients who received a liver transplant from September 2016–September 2019 at our institution.Clinical variables were retrospectively extracted from the electronic medical record.Back-table donor biopsies were obtained with donor steatosis percentage retrospectively determined by a boardcertified pathologist.Blood samples were available immediately following liver transplantation.Quantification of plasma IL-33 and complement proteins,C3a and C5a,were determined by enzyme-linked immunosorbent assay.For mRNA expression,RNA was extracted from donor biopsies and used against a 780 gene panel.RESULTS Cohort consisted of 99 donor and recipients.Donor median age was 45 years and 55%male.Recipients had a median age of 59 years with 62%male.The main etiologies were alcoholic hepatitis,nonalcoholic steatohepatitis,and hepatocellular carcinoma.Median MELD-Na at transplant was 21.Donors were grouped based on moderate macrosteatosis(≥30%).Recipients implanted with moderate macrosteatotic grafts had significantly higher peak alanine aminotransferase/aspartate aminotransferase(P<0.001 and P<0.004),and increased incidence of early allograft dysfunction(60%compared to 18%).Circulating IL-33 levels were significantly elevated in recipients of≥30%macrosteatotic grafts(P<0.05).Recipients with detectable levels of circulating IL-33 immediately following reperfusion had significantly higher alanine aminotransferase/aspartate aminotransferase(P<0.05 and P<0.01).Activated complement(C3a and C5a)were elevated in recipients implanted with moderate macrosteatotic grafts.RNA expression analysis of donor biopsies revealed moderate steatotic grafts upregulated genes inflammatory processes while downregulated hepatocyte-produced complement factors.CONCLUSION Circulating IL-33 and activated complement levels immediately following liver reperfusion in recipients of moderate macrosteatotic grafts may identify which patients are at risk of early allograft dysfunction.

Current status and prospects of interleukin-33 in lung area immunity

Interleukin (IL) 33 is a key cytokine in type II immune and airway diseases. It is abundantly expressed in lung epithelial cells and plays an important role in both innate and adaptive immunity. In innate immunity, IL-33 responds promptly to produce an immune response that maintains homeostasis. In adaptive immunity, IL-33 interacts with various immune cells. At the same time, IL-33 also plays an important role in chronic inflammation of the airway and its remodeling. This article reviews the relevant biological knowledge of IL-33 and its research progress in lung immunity, and discusses the related issues of IL-33 as a lung immune test site and therapeutic target.

目的:探讨血清IL-33、血清嗜酸性粒细胞衍生神经毒素(EDN)在呼吸道过敏性疾病中表达水平及其与疾病的关联性。方法:收集某院114例诊断为过敏性哮喘、过敏性鼻炎等呼吸系统疾病患儿为病例组,另选取57例门诊体检健康的受检者为对照组。比较2组研究对象血清IL-33、EDN表达水平。病例组根据患儿血清总IgE(TIgE水平)分为高表达组、低表达组,检测2组患儿血清IL-33、EDN水平、炎性指标及肺功能水平,分析血清炎性指标和肺功能与血清IL-33、EDN的相关性。结果:病例组患儿血清IL-33、EDN水平均高于对照组,差异有统计学意义(P<0.05);高表达组患者血清IL-33、EDN水平和血清炎性指标TNF-ɑ、IL-6、CRP水平均高于低表达组,潮气量(TV)、呼气峰值流速预计值(PEF)则低于低表达组,差异具有统计学意义(P<0.05)。血清IL-33、EDN水平与血清炎性因子TNF-ɑ、IL-6、CRP成正相关,与TV、PEF无明显相关联性(P>0.05)。结论:呼吸道过敏性患者中血清IL-33、EDN表达水平升高,可诱发机体气道炎症,可能影响肺功能,临床进行疾病诊断时可充分评估血清IL-33、EDN水平判断疾病严重程度。
