An Unusual Presentation of Granulomatosis With Polyangiitis (Wegener's) After SARS-CoV-2 Infection.

In this article, we present an unusual case of granulomatosis with polyangiitis (GPA) in a 41-year-old man. The initial presentation of the disease was atypical, with persistent fever, cough, and fatigue, accompanied by elevated inflammatory markers in association with a large, solitary lung lesion observed at the chest X-ray. Despite the presence of an initial radiological picture suggesting pneumonia, the lack of response to antibiotics necessitated a more in-depth evaluation.

Sex X Time Interactions in Lp(a) and LDL-C Response to Evolocumab.

The aim of this study was to evaluate whether there were significant sex x time interactions in lipoprotein(a) (Lp(a)) and low-density lipoprotein cholesterol (LDL-C) response to treatment with the Proprotein Convertase Subtilisin/Kexin type 9 inhibitor (PCSK9i) Evolocumab, in a real-life clinical setting. For this purpose, we pooled data from 176 outpatients (Men: 93; Women: 83) clinically evaluated at baseline and every six months after starting Evolocumab. Individuals who had been on PCSK9i for less than 30 months and nonadherent patients were excluded from the analysis.

Verapamil: prevention and treatment of cardio-renal syndromes in diabetic hypertensive patients?

Patients with diabetes mellitus (DM) often present other chronic comorbidities including arterial hypertension (AH), chronic kidney disease (CKD), ischemic heart disease (IHD) and heart failure with preserved ejection fraction (HFpEF). The frequent association of the latter conditions is considered part of the spectrum of cardio-renal syndromes (CRS), a group of disorders of the heart and kidneys whereby acute or chronic dysfunction in one organ may induce acute or chronic dysfunction of the other. Verapamil is a non-dihydropyridine calcium channel blocker (CCB) widely used in the treatment of hypertension, chronic stable angina, secondary prevention of reinfarction, paroxysmal supra-ventricular tachycardia and for rate control in atrial fibrillation/flutter.

Vegan Diet Health Benefits in Metabolic Syndrome.

Plant-based diets (PBDs) are increasingly consumed by the Italian population and around the world. In particular, among PBDs, the vegan diet is a food pattern characterized by the exclusion of all animal-origin foods. What drives people to adopt this model are mainly ethical, health and environmental reasons.

Mast cells and cancer.

Mast cells (MCs) are a potent proangiogenic factor in tumors, they product several pro-angiogenic factors such as fibroblast growth factor 2 (FGF-2), vascular epithelial growth factor (VEGF), tryptase and chymase. Tryptase is a serine protease classified as α-tryptase and β-tryptase, both produced by MCs. Tryptase degrades the tissues, playing an important role in angiogenesis and in the development of metastases.
