Abstract:
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.
