[Atheroembolic renal disease: risk factors, diagnostics, histology, and therapeutic approaches].

G Ital Nefrol 2021 Oct 26;38(5). Epub 2021 Oct 26.

U.O.C di Nefrologia e Dialisi, A.O. per l'Emergenza "Cannizzaro", Catania, Italy.

The increase in patients' average age, the enhancement of anticoagulation therapy and the growth of vascular interventions represent the perfect conditions for the onset of atheroembolic renal disease. AERD is observed in patients with diffuse atherosclerosis, generally after a triggering event such as surgery on the aorta, invasive procedures (angiography, catheterization of the left ventricle, coronary angioplasty) and anticoagulant or fibrinolytic therapy. The clinical signs are heterogeneous, a consequence of the occlusion of downstream small arterial vessels by cholesterol emboli coming from atheromatous plaques of the aorta, or one of its main branches.

Formation and Cellular Impact of Cholesterol Crystals in Health and Disease.

Adv Biol (Weinh) 2021 11 29;5(11):e2100638. Epub 2021 Sep 29.

Center for Cardiovascular Research, University of Hawaii, 651 Ilalo Street, Honolulu, HI, 96813, USA.

Cholesterol crystals (CCs) were first discovered in atherosclerotic plaque tissue in the early 1900 and have since been observed and implicated in many diseases and conditions, including myocardial infarction, abdominal aortic aneurism, kidney disease, ocular diseases, and even central nervous system anomalies. Despite the widespread involvement of CCs in many pathologies, the mechanisms involved in their formation and their role in various diseases are still not fully understood. Current knowledge concerning the formation of CCs, as well as the molecular pathways activated upon cellular exposure to CCs, will be explored in this review. Read More

Eur J Epidemiol 2021 Nov 30;36(11):1157-1168. Epub 2021 Jun 30.

Department of Endocrinology and Metabolism, Zhongshan Hospital, Fudan Institute for Metabolic Diseases, and Human Phenome Institute, Fudan University, NO.180 Fenglin Road, Shanghai, 200032, China.

Fat mass and fat-free mass are found to be associated with different health outcomes in observational studies, but the underlying causality remains unclear. We aimed to investigate the causal relationships between body composition and cardiometabolic traits using a two-sample Mendelian randomization (MR) approach. Independent genetic variants associated with body fat mass, fat-free mass, and fat percentage in UK Biobank population were used as genetic instrumental variables, and their causal effects on circulatory diseases, type 2 diabetes, glycemic traits, and lipid fractions were estimated from large-scale genome-wide association studies (GWAS) in European populations.

Am J Dermatopathol 2021 Sep;43(9):662-666

Departments of Pathology.

Abstract: Different hydrophilic and hydrophobic polymers are used as lubricious coatings to reduce vascular traumas in minimally invasive percutaneous procedures. Although they are usually very safe, there is still a risk of serious complications in patients undergoing such procedures, mostly derived from the devices' coating detachment and systemic embolization. The lungs are the most common organ involved, followed by the central nervous system. Read More

Crystalopathy - underestimated entity in nephrology.

Vnitr Lek 2020 ;66(6):371-377

Crystal is a solid particle with a geometric shape because its atoms, ions, or molecules are arranged in a regular ordered structure. However, in case of accidental order of the particles, we are talking about the amorphous substances which can also form crystallike particles. Crystallopathy is a disease that involves crystals of crystallike particulate matter in the pathogenesis of tissue injury. Read More

Durvalumab-associated vasculitis presenting as 'the blue toe syndrome'.

BMJ Case Rep 2020 Nov 18;13(11). Epub 2020 Nov 18.

Internal Medicine, St John of Gods Hospital Midland, Perth, Western Australia, Australia.

Durvalumab is a selective, high-affinity human immunoglobulin monoclonal antibody in a class called check point inhibitors, that blocks PD-L1 on tumour cells. Despite clinical success in increasing progression-free survival rates in patients with stage III non-small-cell lung cancer, durvalumab has been associated with immune-related side effects such as pneumonitis and colitis. We present a case of an 84-year-old woman with acral vasculitis presenting as blue toe syndrome, associated with prolonged use of durvalumab. Read More

Mimics of vasculitis.

Rheumatology (Oxford) 2021 01;60(1):34-47

Division of Rheumatology, University of California, Los Angeles, Los Angeles, CA, USA.

While prompt diagnosis of vasculitis is important, recognition of vasculitis mimics is equally essential. As in the case of vasculitis, an approach to mimics based on the anatomic size of vessels can be useful. Infections can mimic vasculitis of any vessel size, including the formation of aneurysms and induction of ANCAs. Read More
