Red cell distribution width related to the severity of the disease in patients with AECOPD.

Aims: This research aims to elucidate the association between red cell distribution width (RDW) and the severity of acute exacerbations of chronic obstructive pulmonary disease (AECOPD).

Patients & Methods: This retrospective study enrolled patients with AECOPD and healthy controls. A comprehensive meta-analysis was further conducted by systematically searching PubMed, Embase, and the Cochrane Library up to 27 April 2023.

The role of serum chloride ion in the prognosis of COPD.

Background: As exacerbations of chronic obstructive pulmonary disease (COPD) are one of the leading causes of hospitalization and are associated with significant mortality, it is particularly important to accurately assess the risk of exacerbations in COPD. Most of the current clinical biomarkers are related to inflammation and few consider how ion levels affect COPD. Chloride ion, the second most abundant serum electrolyte, has been shown to be associated with poor prognoses in several diseases, but their relationship with COPD remains unclear.

The Relationship of Low-Density-Lipoprotein to Lymphocyte Ratio with Chronic Obstructive Pulmonary Disease.

Background: Chronic Obstructive Pulmonary Disease (COPD) has been a concern all over the world because of its high prevalence and mortality. The ratio of low-density-lipoprotein to lymphocyte (LLR) has been widely used to predict the prognosis of cerebral infarction, but its association with COPD is less known. We aim to explore the relationship between LLR and COPD and to investigate its indicative role in the severity and prognosis of COPD.
