摘要:

目的 探讨血磷、血镁水平与老年慢性阻塞性肺疾病急性加重(AECOPD)患者病情及预后的关系。方法 选取158例老年AECOPD患者作为研究对象,按病情分为轻度组(52例)、中度组(46例)、重度组(60例),比较各组的血磷、血镁水平及肺功能指标。采用Pearson相关分析血磷、血镁与病情指标的相关性,根据随访6个月的预后情况分为预后良好组(116例)和预后不良组(42例)。收集并比较2组一般及临床资料,单因素及多因素Logistic回归分析预后影响因素,采用受试者工作特征(ROC)曲线分析相关因素对老年AECOPD患者预后不良的预测价值。结果 重度组血磷、血镁、第1秒用力呼气容积占预计值的百分比(FEV1%预计值)和第1秒用力呼气容积占用力肺活量百分比(FEV1/FVC)低于轻度组和中度组,CURB-65评分高于轻度组和中度组(P<0.05);血磷、血镁与CURB-65评分呈负相关(r分别为-0.369、-0.283,P<0.05),与FEV1%预计值和FEV1/FVC呈正相关(r分别为0.387、0.281及0.220、0.171,P<0.05)。单因素及多因素Logistic回归分析发现,年龄较大是老年AECOPD患者预后不良的独立危险因素,FEV1%预计值、血磷、血镁升高是独立保护因素(均P<0.05);ROC曲线分析显示,年龄、FEV1%预计值、血磷、血镁联合预测的曲线下面积(AUC)高于单项检测(Z分别为4.643、3.745、4.411、4.327,P<0.05)。结论 血磷、血镁水平与老年AECOPD患者病情严重程度相关,年龄、FEV1%预计值、血磷、血镁对预后具有独立预测价值,联合检测可提高预测效能。

Abstract:

Objective To investigate the relationship between serum phosphorus and magnesium levels and disease severity/prognosis in elderly patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods A total of 158 elderly AECOPD patients admitted to our hospital from January 2022 to December 2024 were enrolled as the study subjects. Patients were divided into the mild group (n=52), the moderate group (n=46) and the severe group (n=60) based on disease severity. Serum phosphorus and magnesium levels, as well as pulmonary function indices, were compared between the groups. Pearson correlation analysis was performed to assess the relationship between serum phosphorus/magnesium levels and disease-related indicators. According to the prognosis after 6-month follow-up, patients were categorized into the good prognosis group (n=116) and the poor prognosis group (n=42). The general and clinical data of the two groups were collected and compared. Univariate and multivariate Logistic regression analyses were performed to identify prognostic factors. Receiver operating characteristic (ROC) curve analysis was used to evaluate the value of relevant factors in predicting poor prognosis in elderly patients with AECOPD. Results The serum phosphorus and magnesium levels, the percentage of forced expiratory volume in 1 second to the predicted value (FEV1% predicted) and the percentage of forced expiratory volume in one second to forced vital capacity (FEV1/FVC) were lower in the severe group than those in the mild group and the moderate group, but the CURB-65 score was higher in the severe group compared to the mild group and the moderate group (P<0.05). Serum phosphorus and magnesium levels were negatively correlated with the CURB-65 score (r=-0.369 and -0.283, respectively, P<0.05) and positively correlated with FEV1% predicted value and FEV1/FVC (r=0.387, 0.281 for phosphorus; r=0.220, 0.171 for magnesium; P<0.05). Both univariate and multivariate Logistic regression analyses indicated that older age was an independent risk factor for poor prognosis in elderly AECOPD patients, whereas higher FEV1% predicted value, serum phosphorus and serum magnesium levels were independent prediction factors (all P<0.05). ROC curve analysis demonstrated that the area under the curve (AUC) of the combined prediction of age, FEV1% predicted value, serum phosphorus and serum magnesium was higher than that of the individual indicators (Z=4.643, 3.745, 4.411, 4.327, respectively; P<0.05). Conclusion Serum phosphorus and magnesium levels are correlated with the severity of AECOPD in elderly patients. Age, FEV1% predicted value, serum phosphorus and serum magnesium levels possess independent predictive value for prognosis, and their combined assessment enhances predictive efficacy.
