J Clin Med

November 2024

Department of Cardiology, Haemostaseology and Medical Intensive Care, University Medical Center Mannheim (UMM), Medical Faculty Mannheim, Heidelberg University, European Center for AngioScience (ECAS) and German Center for Cardiovascular Research (DZHK) Partner Site Heidelberg/Mannheim, 68167 Mannheim, Germany.

Article Synopsis
  • Atrial fibrillation (AF) significantly increases the risk of stroke, and identifying risk factors for strokes in AF patients remains complicated, suggesting that existing scoring systems don't capture all relevant details.
  • In a study analyzing patients from the ARENA project, it was found that those with a history of cerebrovascular events (CVE) were generally older, had higher CHADS-VASc scores, and larger left atrial diameters compared to those without CVE.
  • The prognosis for AF patients with CVE was notably worse; they had higher mortality rates and higher stroke occurrences within a year, indicating that factors like atrial remodeling and underlying heart disease may contribute to their increased risk.

Type 2 inflammation in COPD: is it just asthma?

Breathe (Sheff)

October 2024

Division of Immunology, Immunity to Infection and Respiratory Medicine, School of Biological Sciences, Faculty of Biology, Medicine and Health, University of Manchester and Manchester University NHS Foundation Trust, Manchester, UK.

COPD is a heterogeneous condition, with tobacco smoking being the main environmental risk factor. The presence of type 2 (T2) inflammation is a well-recognised feature of asthma; however, it is now apparent that a subset of COPD patients also displays evidence of T2 inflammation with respect to elevated eosinophil counts and altered gene and protein expression of several T2 inflammatory mediators. T2 inflammatory mediators represent an attractive therapeutic target in both COPD and asthma; however, the efficacy of pharmaceutical interventions varies between diseases.

Patients with chronic kidney disease (CKD) are at risk of progressive loss of kidney function, heart failure, and cardiovascular death despite current proven therapies, including renin-angiotensin system inhibitors (RASi), sodium glucose co-transporter-2 inhibitors (SGLT2i), and statin-based regimens. RASi and SGLT2i reduce risk of CKD progression irrespective of primary cause of kidney disease, suggesting they target final common pathways. Targeting aldosterone overactivity with a nonsteroidal mineralocorticoid receptor antagonist (MRA) also reduces cardiorenal risk in patients with albuminuric diabetic kidney disease already treated with RASi.
