Background: Knowledge of the role of the receptor for advanced glycation end products (RAGE), particularly its soluble form (sRAGE), and of its advanced glycation end product (AGE) ligand, N-(carboxymethyl)lysine adducts (CML), is limited in chronic heart failure (CHF) and in chronic obstructive pulmonary disease (COPD). We evaluated whether the AGE/RAGE system is activated in stable CHF and COPD, and whether plasma sRAGE and CML levels are affected by clinical and functional parameters.

Materials And Methods: We measured plasma levels of sRAGE and CML using a sandwich enzyme-linked immunosorbent assay (ELISA) in 143 subjects, aged ≥ 65 years, divided into five groups: 58 with CHF, 23 with COPD, 27 with CHF+COPD and 35 controls (17 healthy smokers and 18 healthy nonsmokers).

Article Synopsis
  • Long-term oxygen therapy (LTOT) benefits survival rates for COPD patients with severe hypoxemia, but adherence to guidelines is inconsistent due to cost and specific patient efficacy concerns.
  • A study analyzed medical records from two Italian universities, where only 46.5% of patients met all three criteria for appropriate LTOT use.
  • Higher adherence rates were noted when LTOT was prescribed by pulmonologists compared to internists, highlighting the need for better monitoring of guideline adherence given the therapy's costs and impact on patient quality of life.

Background And Objective: The coexistence of chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF) increases with age. The occurrence, prognosis and therapeutic implications of concurrent COPD in elderly patients with CHF were investigated.

Methods: One hundred and eighteen consecutive patients, ≥ 65 years old with ≥ 10 pack/years of smoking and with a verified diagnosis of CHF in stable condition, were enrolled.

The EvA study is a European Union-funded project under the Seventh Framework Programme (FP7), which aims at defining new markers for chronic obstructive pulmonary disease (COPD) and its subtypes. The acronym is derived from emphysema versus airway disease, indicating that the project targets these two main phenotypes of the disease. The EvA study is based on the concept that emphysema and airway disease are governed by different pathophysiological processes, are driven by different genes and have differential gene expression in the lung.
