摘要

目的:乳酸脱氢酶(LDH)是一种负责产生乳酸的酶,乳酸是人体缺氧时产生的必要副产品。血液中的 LDH 水平可作为 ARDS、严重 COVID-19 和癌症患者的死亡率预测指标。目的:分析老年人 COVID-19 的临床特征以及 COVID-19 患者 LDH 与呼吸衰竭之间的相关性,以提高临床医生对此类肺炎的识别和处理能力:这是一项单中心回顾性研究。我们对青岛大学附属医院(中国青岛)2022年10月1日至2023年2月1日收治的105例COVID-19患者进行了常规实验室检查。根据入院时的血气分析结果确定呼吸衰竭的诊断:中位年龄为 79 岁。在所有单变量参数中,低密度脂蛋白胆固醇(LDH)、中性粒细胞与淋巴细胞比值(NLR)和凝血酶原时间(PT)是老年 COVID-19 患者发生呼吸衰竭的显著独立危险因素。LDH(AUC=0.829)的特异性最高(96.5%),其临界值为 280.5:结论:LDH、NLR 和 PT 的水平可作为老年 COVID-19 合并呼吸衰竭患者的潜在指标。LDH、NLR 和 PT 检测对需要更严密的呼吸监测和更积极的支持治疗以避免不良预后的患者有益。

LDH and NLR, as inflammatory markers, the independent risk factors for COVID-19 complicated with respiratory failure in elderly patients.

Objective: Lactate dehydrogenase (LDH) is an enzyme that is responsible for the production of lactic acid, which is a necessary byproduct when the body does not have enough oxygen. LDH levels in the blood can be used as a marker to predict mortality in patients with ARDS, severe COVID-19, and cancer. To analyze the clinical characteristics of COVID-19 in the elderly and the correlation between LDH and respiratory failure in COVID-19 patients, to improve the identification and management of this type of pneumonia by clinicians.

Methods: This was a single-center retrospective study. We performed routine laboratory tests in 105 COVID-19 patients admitted to the affiliated hospital of Qingdao University (Qingdao, China) from October 1, 2022 to February 1, 2023. The diagnosis of respiratory failure was established based on the results of blood gas analysis upon admission.

Results: The median age was 79 years. Among all univariable parameters, LDH, neutrophil to lymphocyte ratio (NLR) and Prothrombin Time (PT) were significantly independent risk factors of RF in elderly COVID-19 patients. LDH (AUC=0.829) also had a maximum specificity (96.5%), with the cutoff value of 280.5.

Conclusion: The levels of LDH, NLR, and PT may serve as potential indicators for elderly COVID-19 patients combined with respiratory failure. LDH, NLR and PT assays can be beneficial for patients who need closer respiratory monitoring and more aggressive supportive care to prevent a negative prognosis.

期刊介绍: It is a peer reviewed medical journal published regularly since 1984. It was previously known as quarterly "SPECIALIST" till December 31st 1999. It publishes original research articles, review articles, current practices, short communications & case reports. It attracts manuscripts not only from within Pakistan but also from over fifty countries from abroad. Copies of PJMS are sent to all the import medical libraries all over Pakistan and overseas particularly in South East Asia and Asia Pacific besides WHO EMRO Region countries. Eminent members of the medical profession at home and abroad regularly contribute their write-ups, manuscripts in our publications. We pursue an independent editorial policy, which allows an opportunity to the healthcare professionals to express their views without any fear or favour. That is why many opinion makers among the medical and pharmaceutical profession use this publication to communicate their viewpoint.
