We report a rheumatoid arthritis patient who was treated with etanercept. Serum levels of tumor-necrosis-factor- (TNF-) alpha, soluble-tumor-necrosis-factor receptor- (sTNFR-) I and -II, interleukin- (IL-) 6, and IL-1 beta were measured by ELISA before and during the course of therapy. While the serum levels of IL-6 and IL-1 beta dropped rapidly following the initiation of therapy, the concentrations of TNF-alpha and sTNFR-II steadily increased to a plateau. Although significant clinical efficacy was observed, etanercept had to be discontinued when after 12 weeks of therapy the patient was found to have pneumocystis pneumonia.
我们报告了一名接受依那西普治疗的类风湿性关节炎患者。在治疗前及治疗过程中,通过酶联免疫吸附测定法(ELISA)检测血清中肿瘤坏死因子-α(TNF-α)、可溶性肿瘤坏死因子受体-I(sTNFR-I)和-II(sTNFR-II)、白细胞介素-6(IL-6)以及白细胞介素-1β(IL-1β)的水平。治疗开始后,IL-6和IL-1β的血清水平迅速下降,而TNF-α和sTNFR-II的浓度则稳步上升至平台期。尽管观察到显著的临床疗效,但在治疗12周后患者被发现患有肺孢子菌肺炎,不得不停用依那西普。
