糖尿病足感染患者下肢血管病变与免疫功能及营养状态的关系寇谦1,寇玉2,周丹3西安市第九医院烧伤整形美容科1、营养部2、心内科3,陕西西安710000【摘要】目的探究糖尿病足感染(DFI)患者下肢血管病变(PAD)与免疫功能及营养状态的关系。
方法回顾性分析2020年1月至2022年1月西安市第九医院收治的104例DFI 患者的临床资料。
根据患者是否发生PAD 分为病变组(n =66)和非病变组(n =38),比较两组患者的免疫功能[免疫球蛋白A (IgA)、免疫球蛋白G (IgG)、免疫球蛋白M (IgM)]及营养状态相关指标,采用多因素Logistic 回归分析DFI 患者PAD 的影响因素;根据病变组患者的PAD 程度不同,将其分为A 、B 、C 、D 四个等级,比较其免疫功能与营养状态指标。
结果病变组患者的血红蛋白(HB)、甘油三酯(TG)、总胆固醇(TC)、IgA 、IgG 以及IgM 水平明显低于非病变组,血清肌酐(Cr)水平明显高于非病变组,差异均有统计学意义(P <0.05);经多因素Logistic 回归分析结果显示,HB 、Cr 、IgA 、IgG 及IgM 是DFI 患者PAD 的独立影响因素(P <0.05);不同PAD 等级DFI 患者的IgA 、IgG 、IgM 、HB 及Cr 水平比较,差异均有统计学意义(P <0.05)。
结论DFI 发生PAD 患者免疫功能、营养状态明显下降,均为PAD 的独立影响因素,且与PAD 严重程度密切相关,临床上应给予重点关注。
