ReviewChronic obstructive pulmonary disease's eosinophilic phenotype: Clinical characteristics, biomarkers and biotherapy.
COPD is a chronic, heterogeneous inflammatory disorder of the airways with persistent and poorly reversible airflow limitation, causing symptoms such as cough, shortness of breath, and sputum production. Despite optimal treatment, some patients remain symptomatic due to the disease's heterogeneity, manifesting in various phenotypes. One notable phenotype involves eosinophilic inflammation, with a variable prevalence. ⋯ Recent advances in both clinical trials and spontaneous research have helped understand the biological and clinical characteristics of this phenotype, although no universal consensus has been reached yet on the definition of the cut-off values of the eosinophil peripheral blood count. Moreover, there is evidence of novel emerging biomarkers which might go beyond the sole eosinophil count, while significant advancements in terms of pharmacological treatment have been made, with dupilumab being the first biological drug being licensed for COPD patients with elevated circulating eosinophils in the stable phase. In light of the above, although several papers have been written on the relationship between eosinophils and COPD, in the present work we endeavored to summarize and discuss the pivotal literature findings regarding the eosinophilic COPD in order to help define the biological and clinical features of this peculiar phenotype, with particular attention to the use of established and emerging biomarkers, as well as current and future therapeutic perspectives.

Homocysteine (Hcy) levels are elevated in different conditions, including cardiovascular diseases (CVD), diabetes, and metabolic-associated steatotic liver disease (MASLD). In this observational retrospective study, we analyzed Hcy levels in a population of 901 outpatients, considering its putative etiological role in MASLD. ⋯ Our data suggest an intriguing scenario whereby HHcy is present in patients with MASLD and is associated to lower vitamin D and altered glucose and lipid profile. Thus, considering Hcy levels may help clinicians with the management of patients with increased MASLD risk.

Multicenter StudyThe impact of the COVID-19 Pandemic on hypertension phenotypes (ESH ABPM COVID-19 study).
The COVID-19 pandemic had a major impact on medical care. This study evaluated the influence of the pandemic on blood pressure (BP) control and hypertension phenotypes as assessed by office and 24-hour ambulatory BP monitoring (ABPM). ⋯ These results indicate a negative impact of the COVID-19 pandemic on BP control assessed by hypertension phenotypes.
