Cases and controls were matched for AAV (granulomatosis with polyangiitis [GPA], microscopic polyangiitis [MPA] or eosinophilic granulomatosis with polyangiitis [EGPA]), sex and year of enrollment.

    Persistent eosinophilia can cause cardiac tissue damage, typically in the form of eosinophilic myocarditis, whether the underlying cause is reactive, a clonal myeloid disorder, or idiopathic hypereosinophilic syndrome (HES). Eosinophilic myocarditis ranges from mild localized disease to multifocal widespread infiltrates associated with myocardial necrosis, thrombotic complications and endomyocardial fibrosis. Systemic treatment varies widely depending on the underlying cause, so thorough investigation and precise diagnosis are essential. Read More

    Eosinophilic myocarditis as a first presentation of eosinophilic granulomatosis with polyangiitis (Churg-Strauss syndrome).

    We present the case of a 28-year-old man who presented with chest pain and elevated cardiac biomarkers, with no evidence of acute ischaemia. He had a pronounced eosinophilia, abnormal echocardiographic, cardiac MRI and CT findings. He underwent transbronchial biopsy of carinal lymph nodes and of lung parenchyma. Read More

    Association of ETS1 polymorphism with granulomatosis with polyangiitis and proteinase 3-anti-neutrophil cytoplasmic antibody positive vasculitis in a Japanese population.

    ETS proto-oncogene 1, transcription factor (ETS1) is involved in various immune responses. Genome-wide association studies on systemic lupus erythematosus in Chinese populations identified the association of ETS1 polymorphism in 3' untranslated region, rs1128334A, which was associated with lower ETS1 expression. In view of substantial sharing of susceptibility genes across multiple autoimmune diseases, we examined whether ETS1 is associated with a rare autoimmune rheumatic disease, anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV).

    Gastrointestinal and Hepatic Disease in Vasculitis.
    Rheum Dis Clin North Am 2018 Feb;44(1):1-14
    Denver Veterans Affairs Medical Center, University of Colorado School of Medicine, Denver, CO, USA. Electronic address:
    Vasculitis is an inflammatory condition that targets the blood vessels, which may occur in isolation or as a component of a systemic inflammatory condition. Although many of the vasculitides can directly affect the organs of the gastrointestinal system, some types exhibit a proclivity for certain gastrointestinal and hepatic organs. Often a patient presents with nonspecific symptoms, delaying the diagnosis and treatment of the underlying vasculitis. Read More

    Seronegative granulomatosis with polyangiitis presenting with multiple cranial nerve palsies.
    Neuropathology 2017 Nov 14. Epub 2017 Nov 14.
    Department of Pathology, Seoul National University Hospital, College of Medicine, Seoul, Republic of Korea.
    Granulomatosis with polyangiitis (GPA), previously known as Wegener's granulomatosis (WG), is a rare systemic disease characterized by necrotizing granulomas and vasculitis that usually presents in the respiratory tract and renal system. Here, we report a case of anti-neutrophil cytoplasmic antibody (ANCA)-negative GPA with diagnostic difficulties. Neurologic involvement in GPA is not uncommon, with up to 50% of patients manifesting with neurologic defects; however, it is usually a late event. Read More
