血清維生素D與曲菌特異性抗體在支氣管擴(kuò)張癥患者中的臨床價(jià)值及兩者之間的相關(guān)性

血清維生素D與曲菌特異性抗體在支氣管擴(kuò)張癥患者中的臨床價(jià)值及兩者之間的相關(guān)性摘要：

目的：探討血清維生素D與曲菌特異性抗體在支氣管擴(kuò)張癥（BR）患者中的臨床價(jià)值及兩者之間的相關(guān)性。

方法：我們招募了114名確診為BR的患者作為研究對象?；颊叩难寰S生素D水平以及曲菌特異性抗體（IgG，IgA，IgM）水平均進(jìn)行了檢測，并且對兩者之間的相關(guān)性進(jìn)行了分析。

結(jié)果：BR患者中，血清維生素D水平低于正常范圍的比例達(dá)到了74.6%。同時(shí)，曲菌特異性抗體水平也普遍升高，其中IgG水平最高。在BR患者中，血清維生素D水平與曲菌特異性抗體水平呈現(xiàn)負(fù)相關(guān)性，且相關(guān)性程度隨著BR的程度加重而加強(qiáng)。

結(jié)論：血清維生素D水平與曲菌特異性抗體水平可以作為BR的輔助診斷指標(biāo)，同時(shí)兩者之間的負(fù)相關(guān)性也為BR的治療提供了新思路。

關(guān)鍵詞：支氣管擴(kuò)張癥、血清維生素D、曲菌特異性抗體、相關(guān)性
