Special Issue Information

Dear Colleagues,

COPD is one of the most important problems in respiratory medicine. The disease demonstrates adverse trends in prevalence, as well as in its impact on quality of life and prognosis. In turn, the clinical significance of atherosclerosis is emphasized by the heavy medical, economic and social burden on patients, society and health care systems in many countries. It is important to note that COPD and atherosclerosis often occur in the same patient, and in most cases, it is impossible to determine exactly which one developed first. The diseases are often diagnosed in an untimely manner and mutually worsen each other's course, affecting the patient’s quality of life and prognosis. These and other data draw clinicians’ and researchers’ attention to the comorbid course of COPD and atherosclerosis.

A growing amount of evidence suggests an immune and metabolic axis that links COPD and atherosclerosis in their comorbid development and course. Metabolic dysregulation is one of the most important links in the complex chain of processes underlying the pathogenesis of both COPD and atherosclerosis. Immunometabolic switching of immune cells is an important part of inflammation in both COPD and atherosclerosis. It should be noted that the key to understanding many links in the pathogenesis of both isolated and comorbid courses of COPD and atherosclerosis is still largely unknown by clinicians and researchers.

Thus, this Special Issue focuses on original research and thorough reviews of recent advances concerning the metabolic and immune mechanisms underlying COPD and atherosclerosis. These articles can focus on various research aspects that will help to improve the understanding of the metabolic links and their pathophysiological and clinical significance.

The Controlling Nutritional Status (CONUT) score is a simple screening tool able to assess poor nutritional status as well as to predict clinical adverse outcomes in different clinical settings. No data are available in older patients with chronic obstructive pulmonary disease (COPD). This study aimed to investigate the CONUT score as a predictor of frequent exacerbations. We retrospectively enrolled 222 patients aged 65 years or older, classified in two groups according to the number of exacerbations (or hospitalizations because AECOPD) during the previous year. The two groups were further divided according to low (<5) or high (≥5) CONUT scores. A total of 67.2% of frequent exacerbators had a high CONUT score. These patients exhibited a significantly higher CAT score, lower FEV1 percentage value, and higher prevalence of severe GOLD stages compared to those with low CONUT. Multivariate analysis showed that a CONUT score ≥ 5 was the best independent predictor (OR 20.740, p < 0.001) of the occurrence of ≥2 exacerbations (or 1 hospitalization) during the previous year. The CONUT score seemed to have a high prognostic value for frequent exacerbations for COPD in older patients. The predictive role of different CONUT score cut-off values needs to be validated in larger COPD populations in future multi-center, prospective clinical studies. Full article

Mild-to-moderate pulmonary hypertension (PH) is a common complication of chronic obstructive pulmonary disease (COPD). It is characterized by narrowing and thickening of the pulmonary arteries, resulting in increased pulmonary vascular resistance (PVR) and ultimately leading to right ventricular dysfunction. Pulmonary vascular remodeling in COPD is the main reason for the increase of pulmonary artery pressure (PAP). The pathogenesis of PH in COPD is complex and multifactorial, involving chronic inflammation, hypoxia, and oxidative stress. To date, prostacyclin and its analogues are widely used to prevent PH progression in clinical. These drugs have potent anti-proliferative, anti-inflammatory, and stimulating endothelial regeneration properties, bringing therapeutic benefits to the slowing, stabilization, and even some reversal of vascular remodeling. As another well-known and extensively researched prostaglandins, prostaglandin E2 (PGE2) and its downstream signaling have been found to play an important role in various biological processes. Emerging evidence has revealed that PGE2 and its receptors (i.e., EP1–4) are involved in the regulation of pulmonary vascular homeostasis and remodeling. This review focuses on the research progress of the PGE2 signaling pathway in PH and discusses the possibility of treating PH based on the PGE2 signaling pathway. Full article
