目的探讨初诊2型糖尿病(T2DM)患者血小板分布宽度(PDW)对糖尿病周围神经病变(DPN)发生风险的影响。方法回顾性分析2017年1月至2021年12月于徐州医科大学附属徐州市立医院内分泌科住院的1001例初诊T2DM患者的临床资料,采集患者一般资料、血小板相关指标和生化指标,根据有无DPN将患者分为DPN组(n=481)和非DPN组(n=520)。采用易侕软件和R3.4.3进行数据分析。根据数据类型,分别采用t检验、Mann-Whitney U检验或χ^(2)检验进行组间比较。对PDW与生化指标进行Pearson相关性分析。采用logistic回归分析PDW是否为DPN风险的独立影响因素。采用多元线性回归分析PDW是否为神经传导速度的独立影响因素。结果DPN组PDW水平较非DPN组显著增高[(14.58±2.26)和(14.20±2.41)fl,P=0.01]。校正一般资料、血小板相关指标、生化指标的多因素logistic回归分析结果显示,PDW水平是DPN独立危险因素,PDW每增加1个单位DPN风险增加11%(OR=1.11;P<0.05),PDW每增加1个标准差DPN风险增加29%(OR=1.29;P<0.05)。与第一分位相比,PDW在第三分位(OR=2.43;P=0.01)和第四分位(OR=2.01;P<0.05)时DPN风险显著增加。将DPN作为定量指标进行多因素线性回归分析,结果显示PDW水平是神经传导速度独立危险因素。结论初诊T2DM患者中,有DPN者PDW水平较非DPN者显著升高,PDW水平增高是DPN风险的独立危险因素。
