DETERMINATION OF URINE TUMOR NECROSIS FACTOR, IL-6, IL-8 AND SERUM IL-6 IN PATIENTS WITH HEMORRHAGIC FEVERS WITH RENAL SYNDROME

Objective To explore the roles of cytokines in the pathogenesis of hemorrhagic fever with renal syndrome（HFRS）. Methods Double-antibody sandwich ELISA was used to determine serum interleukin （IL）-6, urine tumor necrosis factor （TNF）, IL-6 and IL-8 levels in 56 patients with HFRS. Results Serum IL-6, urine TNF, IL-6 and IL-8 concentrations in HFRS patients were significantly higher than those in control group, respectively （P〈0. 001）. The concentrations increased at fever stage, then continued to increase during hypotension stage and peaked at oliguria stage. The concentrations of serum IL-6, urine TNF, IL-6 and IL-8 increased in accord with the severity of the disease and differed greatly among different types of the disease. Serum IL-6 had remarkable relationships with serum specific antibodies. It was positively related to serum β2 -microglobulin （β2 -MG）, blood ureanitrogen （BUN） and creatinine （Cr）. Significant positive relationships were also found both between urine IL-6 and TNF, and between IL-6 and IL-8 （r=0.5768, P〈0.05; r=0. 3760, P〈0.01）. Conclusion TNF, IL-6 and IL-8 activated during the course of the disease. IL-6 is associated with the immunopathological lesions caused by the hyperfunction of humoral immune response. IL-6, IL-8 and TNF are involved in the renal immune impairment. Determining them might, in certain extent, be used in predicting the prognosis and outcome of patients with HFRS.

EXPRESSION OF IL-2 AND SIL-2R AND ALTERATION OF CELL IMMUNITY IN PATIENTS WITH HYPERTENSIVE CEREBRAL HEMORRHAGE

Objective To study the expression of interleukin-2 （IL-2）, soluble interleukin-2 receptor （sIL-2R）, determine the alteration of erythrocytic immunity and T cell subgroup in the blood of outer circulation in patients with hypertensive cerebral hemorrhage so and to probe into the relationship between them, and to explore the clinical significance. Methods Enzyme linked immnunosorbent assay （ELISA） was used to determine the content of IL-2 and slL-2R. The immunoadsorption was employed to examine the erythrocytic immune activity and its regulating function. （ S-P） was used to determine the cell number of CD3 （cluster of differentiation3）, CD4 and CD8. Resolts The content of IL-2 in the group with hypertensive cerebral hemorrhage was significantly lower than that in the control group （P〈0.01）, and the content of sIL-2R increased. Red blood cell C3b receptor （RBC. C3bR） and RBC immune adherence enhancing factor （RFEB） dropped greatly （P〈0.01）, while RBC immune complex rosette （RBC. ICR） and RBC immune adherence inhibiting factor （RFIR） increased greatly. The cell number of CD3 and CD4decreased （P〈0.01） and there was no obvious change in CD8 （P〈 0. 05）. Conclusion The decrease of immune function was observed in patients with hypertensive cerebral hemorrhage. The determination of the content of IL-2, sIL- 2R, erythrocytic immunity and the activity of T subgroup has an important clinical significance in the occurrence, development, treatment, and prognosis of hypertensive cerebral hemorrhage.

肾综合征出血热患者白细胞介素-6的动态变化及意义

用双抗体夹心ELISA法检测36例肾综合征出血热102份系列血清中IL－6含量，发现患者血清IL－6含量在6病日前及发热低血压期均高于正常；6病日达高峰，7病日开始下降；发热期明显升高，少尿期达峰值；IL－6含量在轻、中、重及危重型患者之间有明显差异；IL－6与尿蛋白在含量间明显正相关。提示IL－6含量变化与病程进展一致，是引起肾病综合征出血热病理损伤的重要因素之一；且与病情轻重密切相关，可一定程度判定患者预后和转归，反映肾损伤程度。     

MacEUSA和IFA对EHF病人血清SIgM的动态检测

用IgM抗体捕获法ELISA(MacELISA)和间接免疫荧光法(IFA)同时检测32例流行性出血热(EHF)病人血清特异性lgM抗体(SIgM)的动态反应。二法检出SIgM的总符合率为99.46%,所测抗体滴度的动态反应曲线基本平行,而MacELISA所测抗体滴度比IFA明显提高。早期EHF病人血清即有较高滴度的SIgM抗体,9病日～10病日达高峰,此后趋于下降。IFA法所测不同病日的SIgM滴度无显著差异(F=1.680,P>0.05),而MacELISA则有显著差异(F′=2.978,P<0.05)。二法所测不同病型EHF的SIgM滴度在病日相同时各型间皆无显著差异(P>0.05)。     

肾综合征出血热患者血浆心房利钠因子含量的变化及其意义

本文应用特异性的心房利钠因子(ANF)抗体,测定了20例健康人和51例肾综合征出血热(HFRS)患者血浆ANF含量。结果表明,健康人血浆ANF含量与HFRS患者有显著性差异HFRS组中,除恢复期外,各期ANF均升高,其中以少尿期最突出;ANF的血浆浓度与病情轻重有一定关系,提示血浆ANF含量的变化与肾功能损害程度有很大关系。     

IgM抗体捕获ELISA法对流行性出血热患者尿液中特异性IgM抗体的检测

将IgM抗体捕获ELISA法应用于检测流行性出血热病人尿液中的特异性IgM抗体,总阳性率72.62%,7～9病日可达83.87%;第3病日即可出现阳性;并且具有较高的特异性和敏感性。尿中特异性IgM抗体检出的阳性率与病日(G=7.3858,P>0.05)及尿蛋白含量(G=4.4003,P>0.05)间均无明显关系;特异性IgM抗体的滴度与病日有关(F′=26.5331,P<0.01)与尿蛋白含量无明显关系(F=2.2074,P>0.05);不同病日尿液中特异性IgM抗体检出的阳性率与滴度呈正相关(r=0.9973,P<0.01)。     

EHF患者特异性IgG动态变化及其与病型的关系

用间接免疫荧光法对32例流行性出血热(EHF)患者病程中血清特异性IgG(SIgG)抗体变化作了动态检测,分析了SIgG的变化与病型的关系。结果表明,SIgG可于第3病日检出,此后其阳性率和滴度随病日的延长而增高,至第11～12病日,阳性率达100%,滴度趋于稳定的高水平。不同病型EHF有不同的SIgG反应,于第7～8病日,不同病型的SIgG滴度出现显著差异(F=4.004,P<0.05)。提示SIgG在EHF的免疫病理损伤中起一定作用。     

病毒唑对EHF患者特异性体液免疫及循环免疫复合物的影响

本文对病毒唑治疗的流行性出血热(EHF)患者血清EHF—IgG及循环免疫复合物(CIC)进行了系统的动态观察,结果显示病毒唑治疗组患者血清EHF—IgG抗体及CIC水平皆比对照组为低。说明用药后患者体内特异性体液免疫反应降低,CIC形成减少,有利于病情改善。     

酶联免疫吸附试验检测流行性出血热患者IgM抗体报告

本文介绍一种检测EHF特异性IgM抗体的ELISA间接法,在临床诊断应用中分别对耳血及静脉血清进行了平行检查,并与IFAT法进行了比较。结果表明:19例临床诊断为EHF患者耳血中ELISA—IgM阳性率为100％(19/19),IFAT—IgM阳性率为89.47％(17/19),且ELISA耳血IgM抗体滴度>IFAT耳血IgM抗体滴度者为68.47％(13/19)。实验发现,耳血ELISA—IgM抗体滴度明显高于静脉血清ELISA—IgM抗体滴度4倍者占73.68％(14/19)。作者认为,该方法特异性、敏感性较好,操作简便,只需要采用耳血就可以达到早期,快速诊断目的,值得推广使用。     

中和抗体在流行性出血热病程中的动态改变及意义

采用微量细胞病变中和试验对１５例流行性出血热（ＥＨＦ）患者的中和抗体进行了动态检测。第３病日即可检出，５病日内检出率为７８％（７／９），至第１５～１６病日达高峰，中和抗体的滴度变化与ＥＨＦ的病期和病型有明显关系，轻型、中型、重型患者随病程进展而升高，危重型患者发热期滴度最高，死亡前中和抗体滴度明显降低；中和抗体的滴度与尿蛋白的变化呈负相关。动态检测中和抗体的滴度变化可反映患者的转归和预后，若重症患者中和抗体极度降低，则预后不良，这对探索ＥＨＦ的发病机理有重要意义。
