Eosinophilic pericardial effusion in a cat with complex systemic disease and associated peripheral eosinophilia.

J Vet Cardiol 2021 Mar 17;35:55-62. Epub 2021 Mar 17.

Cardiopulmonary and Internal Medicine Service, Hospital for Small Animals, Royal (Dick) School of Veterinary Studies & The Roslin Institute, The University of Edinburgh, Roslin, Midlothian, EH25 9RG, UK.

An 11-year-old domestic shorthair cat was referred for investigation of dry cough of 1-week duration and cardiomegaly. Echocardiography revealed pericardial effusion, and eosinophils were identified as the predominant cell type in fluid collected by pericardiocentesis. Thoracic computed tomography imaging and bronchoscopy were supportive of mild lower airway disease, while bronchoalveolar lavage confirmed eosinophilic inflammation and concurrent Mycoplasma felis infection.

Waterproofing spray-associated pneumonitis review: Comparison with acute eosinophilic pneumonia and hypersensitivity pneumonitis.

Medicine (Baltimore) 2021 Mar;100(10):e25054

Respiratory Disease Center, Fukujuji Hospital, Japan Anti-tuberculosis Association, Kiyose City, Tokyo, Japan.

Abstract: Waterproofing spray-associated pneumonitis (WAP) proceeds to acute respiratory failure and is characterized by diffuse bilateral ground-glass opacities on computed tomography; however, the detailed characteristics of WAP are unknown. Therefore, this study identified the characteristics of WAP from comparisons with those of acute eosinophilic pneumonia (AEP) and hypersensitivity pneumonitis (HP), which show similar features to WAP.Adult patients with WAP, AEP, and HP treated in Fukujuji Hospital from 1990 to 2018 were retrospectively enrolled.

Eosinophilic Granulomatosis With Polyangiitis: Dissecting the Pathophysiology.

Front Med (Lausanne) 2021 24;8:627776. Epub 2021 Feb 24.

Department of Experimental and Clinical Medicine, University of Firenze, Firenze, Italy.

Eosinophilic Granulomatosis with Polyangiitis (EGPA) is a rare multisystemic disease classified both amongst hypereosinophilic disorders and ANCA-associated vasculitis. Vessel inflammation and eosinophilic proliferation are the hallmarks of the disease and main effectors of organ damage. Two distinct disease phenotypes have classically been described according to ANCA-status: the ANCA-negative subset with eosinophil-driven manifestation and the ANCA-positive one with vasculitic manifestations.

Development and application of novel immunoassays for eosinophil granule major basic proteins to evaluate eosinophilia and myeloproliferative disorders.

J Immunol Methods 2021 Jun 6;493:113015. Epub 2021 Mar 6.

Division of Allergic Diseases, Department of Medicine, Mayo Clinic, Rochester, MN, United States of America; Departments of Dermatology and Medicine, University of Utah, Salt Lake City, UT, United States of America.

Background: During eosinophil differentiation, the granule eosinophil major basic protein 1 (eMBP1) is synthesized as a 32-kDa precursor form, referred to as proMBP1, which is processed into the 14-kDa mature form of eMBP1. The prevalence of these two forms of MBP1 in most pathological conditions remains unknown.

Objective: To develop the immunoassays that differentiate mature eMBP1 and proMBP1 and apply them to analyze their levels in biological fluids from patients with eosinophilia and hematologic disorders. Read More

Caspian J Intern Med 2021 ;12(1):107-110

Department of Cardiology, Cheng Hsin General Hospital, Taipei, Taiwan.

Background: Loeffler's endocarditis is a rare disease, caused by endocardial involvement of esosinophils, which damages the heart and leads to endomyocardial fibrosis with consequent restrictive cardiomyopathy, mural thrombi or valvular dysfunction. The association between Loeffler's endocarditis and Churg-Strauss syndrome (CSS) was also reported. Abnormal elevation of peripheral eosinophil counts in a heart failure patient is a hint of disease.
