Abstract

To determine the effects of penicillin and erythromycin on cytokine production induced by heat-killed Streptococcus pneumoniae (HKSP), we studied the effects of those drugs on cytokine production induced by S. pneumoniae in human whole blood in vitro and ex vivo. In whole blood in vitro, erythromycin, but not penicillin, caused a dose-dependent decrease in HKSP-induced production of tumor necrosis factor alpha (TNF) and interleukin 6 (IL-6), while the production of IL-10, IL-12, and gamma interferon was inhibited only at the highest erythromycin concentration tested (10(-3) M). The production of TNF and IL-6 in whole blood obtained from healthy subjects after a 30-min infusion of erythromycin (1,000 mg) was lower after ex vivo stimulation with HKSP than that in blood drawn before the infusion. Inhibition of TNF contributed to erythromycin-induced inhibition of IL-6 synthesis. Inhibition of TNF and IL-6 production by erythromycin may have a negative impact on host defense mechanisms during pneumococcal pneumonia.

摘要

为了确定青霉素和红霉素对热灭活肺炎链球菌(HKSP)诱导的细胞因子产生的影响,我们在体外和体内研究了这些药物对人全血中肺炎链球菌诱导的细胞因子产生的影响。在体外全血中,红霉素而非青霉素导致HKSP诱导的肿瘤坏死因子α(TNF)和白细胞介素6(IL-6)产生呈剂量依赖性下降,而IL-10、IL-12和γ干扰素的产生仅在测试的最高红霉素浓度(10⁻³ M)下受到抑制。在健康受试者输注红霉素(1000 mg)30分钟后获得的全血中,用HKSP进行体外刺激后,TNF和IL-6的产生低于输注前抽取的血液中的产生。TNF的抑制导致红霉素诱导的IL-6合成抑制。红霉素对TNF和IL-6产生的抑制可能对肺炎球菌肺炎期间的宿主防御机制产生负面影响。
