Introduction: Lung biopsy in asthmatic patients is justified in case of atypical presentations of asthma, when other differential diagnoses, such as hypersensitivity pneumonitis or eosinophilic granulomatosis with polyangiitis, could be possible or for research purposes.

Aim: We aim to describe the utility and the safety of TBLC (transbronchial lung cryobiopsy) in asthmatic patients, providing data on the pathological changes occurring in the airways and in the lung parenchyma.

Methods: We reviewed asthmatic patients that underwent TBLC, that eventually had only a final diagnosis of asthma. Read More

Vasculitis refers to inflammation of the systemic vessels. Eosinophilic granulomatosis with polyangiitis (EGPA) is a medium and small vessel vasculitis characterized by hypereosinophilia, pulmonary infiltrates, difficult to treat asthma and polyneuropathies. Diagnosis can often be challenging. Read More

Background/purpose: Granulomatosis with polyangiitis (GPA) is a type of primary systemic vasculitis associated with the presence of anti-neutrophil cytoplasmic antibodies (ANCA). GPA mainly affects medium and small vessels and may manifest in different organs, most commonly upper respiratory tract. Oral lesions occur in 6-13% of GPA patients and might be the first symptom observed by the patient. Read More

Antineutrophil cytoplasm antibodies (ANCA)-associated vasculitides are necrotizing vasculitis affecting small blood vessels and include granulomatosis with polyangiitis (formerly Wegener's), microscopic polyangiitis and eosinophilic granulomatosis with polyangiitis (formerly Churg-Strauss syndrome). Diagnosis of ANCA-associated vasculitis is based on the clinical presentation, ANCA positivity directed against proteinase 3 or myeloperoxidase, and when possible on histological evidence of vasculitis. Evolution of ANCA-associated vasculitides without treatment leads constantly to death. Read More

Purpose: To assess how often non-infectious anterior scleritis remits and identify predictive factors.

Methods: Our retrospective cohort study at four ocular inflammation subspecialty centers collected data for each affected eye/patient at every visit from center inception (1978, 1978, 1984, 2005) until 2010. Remission was defined as inactivity of disease off all suppressive medications at all visits spanning at least three consecutive months or at all visits up to the last visit (to avoid censoring patients stopping follow-up after remission).

Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare form of vasculitis disorder which involves multiple organ systems and is characterized by asthma, pulmonary infiltrates, sinusitis, neuropathy, and peripheral eosinophilia. It also has an effect on the heart, skin, kidneys, and gastrointestinal tract. Interlukin-5 (IL-5) is involved in maturation and activation of eosinophil, the production of which is increased in the EGPA. Read More

Among the eosinophilic diseases treated by rheumatologists other than eosinophilic granulomatosis with polyangiitis, there are further organ-related and systemic diseases with hypereosinophilia. Only the exact differential diagnostic demarcation of the diseases enables a pathogenetic oriented treatment. This article focuses on the hypereosinophilic syndromes. Read More

Objectives:: The aim of this study was to review the histologic diagnostic yield of airway biopsies with a suspected granulomatosis with polyangiitis (GPA) diagnosis at a single center devoted to respiratory diseases using previously published criteria. A secondary aim was to apply the algorithm proposed by the European Medicines Agency to determine whether more biopsies were confidently identified as having GPA diagnoses.

Methods:: From a total of 132 airway biopsies (2005-2015), 50 were randomly selected for second review by an expert pathologist, and previously published criteria were applied. Read More

Background: An example of aggressive eosinophilic polyposis can be found in eosinophilic granulomatosis with polyangiitis (EGPA). Intercellular adhesion molecule-1 (iCAM-1) and vascular cell adhesion molecule-1 (vCAM-1) play a part in mediating the recruitment and adhesion of leukocytes to the vessel wall, and their blood-to-tissue migration under inflammatory conditions.

Objective: This prospective study compared 3 groups-patients with a definite diagnosis EGPA, non-EGPA patients with phenotypic features suggestive of EGPA, and patients with non-eosinophilic nasal polyposis (controls)-in terms of nasal tissue histology, iCAM-1 and vCAM-1 expression, and blood inflammatory cells.

Nasal biopsy is the essential method for differentiating and diagnosing granulomatosis with polyangiitis (GPA) in patients with chronic rhinosinusitis. Nevertheless, in the real clinical settings, there are several cases unable for nasal biopsy. Hence, in this study, we investigated initial clinical manifestations and laboratory factors which could be helpful for diagnosing GPA in cases unable for nasal biopsy performance. Read More

Background: Anti-neutrophil cytoplasmic antibodies associated vasculitides (AAV) are characterized by autoimmune small vessel inflammation. Eosinophils are multifunctional cells with both pro-inflammatory and immunoregulatory properties. Tissue activated eosinophils secrete cyto- and chemokines and form extracellular traps (EETs), they release free granules and produce reactive oxygen species. Read More

Granulomatosis with polyangiitis (GPA) is a rare systemic autoimmune disease of unknown etiology that is characterized by granulomatous inflammation, tissue necrosis, and vasculitis in small- and medium-sized vessels. Ocular and orbital manifestations are common in almost half of patients with GPA, affecting every structure of the eye, from the eyelid and orbit to the retina, the choroid, and the optic nerve, with a wide range of severity. Since imaging findings are not always specific for the diagnosis of GPA, biopsy is useful to confirm the diagnosis. Read More

Granulomatosis with polyangiitis (GPA) was diagnosed in a patient with a 16-month history of IgG4-related lung disease that spontaneously became asymptomatic. Cytoplasmic antineutrophil cytoplasmic antibody (ANCA) was positive at the time of diagnosis of IgG4-related disease (IgG4-RD), but there was no vasculitis or kidney disease. Sixteen months later he developed rapidly progressive glomerulonephritis that responded to cyclophosphamide treatment. Read More
