在 23 名 HIV 血清阳性 (HIV+) 患者的支气管肺泡灌洗 (BAL) 液和血液中,测量了白细胞介素 1β (IL-1)、肿瘤坏死 α (TNF)、白细胞介素 6 (IL-6)、白细胞介素 1 受体拮抗剂 (IL-1RA) 和 TNF 可溶性受体(sTNF 受体、P55 和 P75)的浓度和离体产生量。卡氏肺囊虫肺炎 (PCP) 并与健康 HIV 血清阴性 (HIV−) 对照和无症状 HIV+ 受试者中发现的值进行比较。与健康对照受试者中检测不到的水平相比,患有PCP的HIV+患者的BAL液中促炎细胞因子IL-1β的浓度升高(184 ± 47 pg mL−1)(P = 0.0001)。在这些患者的血浆中,急性 PCP 期间的抗炎细胞因子 IL-1RA 浓度高于恢复后(2.1 ± 0.7 vs. 0.5 ± 0.2 ng mL−1,P = 0.01)。细胞因子浓度与感染的临床严重程度之间没有发现相关性。皮质类固醇治疗不会影响 BAL 或血液中的细胞因子浓度,也不会抑制肺泡细胞的产生。然而,在全血培养物中,脂多糖 (LPS) 刺激的 IL-1(1.3 vs. 5.5 ng mL−1,P = 0.009)和 IL-6(0.6 vs. 2.5 ng mL−1,P = 0.01)显着受到抑制。总体数据显示,在患有 PCP 的 HIV+ 患者中(类似于我们之前在患有 PCP 的 HIV- 患者中发现的情况),促炎细胞因子在 BAL 中更为突出,而抗炎反应在循环中占主导地位。
Concentrations and ex vivo production of interleukin 1β (IL‐1), tumour necrosis α (TNF), interleukin 6 (IL‐6), interleukin‐1 receptor antagonist (IL‐1RA) and TNF soluble receptors (sTNF‐receptors, P55 and P75) were measured in bronchoalveolar lavage (BAL) fluid and blood in 23 HIV‐seropositive (HIV+) patients with Pneumocystis carinii pneumonia (PCP) and compared with values found in healthy HIV‐seronegative (HIV−) controls and asymptomatic HIV+ subjects. Concentrations of the proinflammatory cytokine IL‐1β were increased in BAL fluid of HIV+ patients with PCP (184 ± 47 pg mL−1) compared with undetectable levels in healthy control subjects (P = 0.0001). In plasma of these patients higher concentrations of the anti‐inflammatory cytokine IL‐1RA were found during acute PCP than after recovery (2.1 ± 0.7 vs. 0.5 ± 0.2 ng mL−1, P = 0.01). No correlations could be found between cytokine concentrations and clinical severity of the infection. Corticosteroid treatment did not influence cytokine concentrations in BAL or blood, nor did it suppress the production in alveolar cells. In whole‐blood cultures, however, lipopolysaccharide (LPS)‐stimulated production was significantly suppressed for IL‐1 (1.3 vs. 5.5 ng mL−1, P = 0.009) and for IL‐6 (0.6 vs. 2.5 ng mL−1, P = 0.01). The overall data show that in HIV+ patients with PCP (similar to what we had found previously in HIV− patients with PCP) proinflammatory cytokines are more prominently present in BAL, whereas anti‐inflammatory reaction is predominant in the circulation.
