目的 研究下呼吸道感染(LRTI)患者外周血β-防御素2(HBD-2)與全身炎癥反應(yīng)的關(guān)系。方法 LRTI組納入81例患者,包括社區(qū)獲得性肺炎、COPD急性加重或(和)合并肺部感染、支氣管擴(kuò)張合并感染。同期20例健康人作為對(duì)照組。酶聯(lián)免疫吸附法(ELISA)測(cè)定外周血HBD-2、白細(xì)胞介素1β(IL-1β)和IL-8水平。常規(guī)進(jìn)行血細(xì)胞分析等實(shí)驗(yàn)室檢查。比較LRTI組及對(duì)照組上述指標(biāo)的變化。按照采血時(shí)患病時(shí)間分為 lt;7 d組、7~14 d組和 gt;14 d組,比較組間差別。對(duì)HBD-2與IL-1β、IL-8進(jìn)行相關(guān)分析。結(jié)果 LRTI組患者外周血HBD-2、IL-1β和白細(xì)胞總數(shù)(WBC)顯著高于對(duì)照組(P均 lt;0.05)。LRTI患者在患病時(shí)間 lt;7 d組和7~14 d組的HBD-2和IL-1β水平均顯著高于對(duì)照組(P均 lt;0.05), gt;14 d組患者的HBD-2和IL-1β基本恢復(fù)正常(P均 gt;0.05)。不同患病時(shí)間的LRTI患者IL-8水平?jīng)]有顯著差異(P均 gt;0.05)。外周血HBD-2與IL-1β呈顯著的正相關(guān)(r=0.313,P=0.030);HBD-2與IL-8無(wú)顯著相關(guān)性(P gt;0.05)。結(jié)論 LRTI患者外周血HBD-2明顯升高;HBD-2升高主要表現(xiàn)在疾病早期或相對(duì)早期;外周血HBD-2升高可能與全身炎癥反應(yīng)有關(guān)。
