Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis is characterized as inflammation of small-sized to medium-sized blood vessels and encompasses several clinicopathologic entities including granulomatosis with polyangiitis, microscopic polyangiitis, eosinophilic granulomatosis with polyangiitis, and renal-limited ANCA-associated vasculitis. Over the past several decades, significant progress has been made in understanding the pathophysiology of ANCA-associated vasculitis. Although neutrophils contain a multitude of granular proteins, clinically significant autoantibodies are only recognized against myeloperoxidase and proteinase 3, both of which are present in the azurophilic granules...

Granulomatosis with polyangiitis (GPA) is more frequent in Northern rather than Southern countries. Very few studies have been conducted in Africa. We have performed a retrospective descriptive study including clinical and laboratory profiles of 30 Tunisian GPA patients seen at the department of Internal Medicine of the University Hospital of la Rabta from 2000 to 2014. Mean age at initial GPA diagnosis was 46±12 years, and the average number of months between the onset of symptoms and diagnosis was 25. Seventeen (56%) were male, and 13 (44%) were female...

A 44 year old lady presented with acute onset of loss of vision in the right eye and cough with mucopurulent expectoration for two months. Ophthalmic examination revealed central retinal artery occlusion (CRAO). Chest radiograph showed multiple cavitatory nodules with fluid levels. Sputum was negative for AFB and ANCA was strongly positive suggestive of a diagnosis of Granulomatosis with Polyangiitis (GPA). Within the next few weeks the patient had rapid detenoration due to left eye CRAO, progressive bilateral hearing loss, facial palsy and retro orbital mass...

Granulomatous orbital cellulitis is one of the most common ocular manifestations of granulomatosis with polyangiitis (Wegener's). The process is often refractory to conventional immunosuppressive therapy and requires a more radical treatment approach. However, surgical experience with this type of patients is limited. There have been just a few reported cases of orbital decompression in such patients and many authors have doubted the appropriateness of the procedure, since it is associated with a high risk of potentially fatal complications...

BACKGROUND: B cell depletion with rituximab (RTX) is approved for treatment of rheumatoid arthritis (RA) and ANCA-associated vasculitides (AAV). Recently, RTX has been shown to be effective in AAV maintenance therapy, but an optimal RTX treatment schedule is unknown and the time to B cell repopulation after RTX has not been studied. METHODS: Retrospective single-center analysis of B cell repopulation in patients with AAV, RA or connective tissue disease (CTD) treated with RTX...

BACKGROUND: Macrophages may present two distinct phenotypes indicated as M1 and M2 under different stimuli. M1 and M2 macrophages have divergent functions that range from enhancement of inflammation for M1 to tissue repair and remodeling for M2 macrophages. The objective of this study was to evaluate the distribution of M1 and M2 macrophage phenotypes in biopsies from the airways of patients with active granulomatosis with polyangiitis (GPA) and to analyze their associations with T and B cells in those biopsies, and with nasal carriage of Staphylococcus aureus, disease parameters and therapy...

BACKGROUND: Influenza vaccine is safe and effective for the general population as well as for patients with autoimmune diseases. However, although rare, vasculitis has been reported as an adverse event following influenza vaccination. OBJECT: The aims of this literature review were to identify patients who developed vasculitis following influenza vaccination and to clarify the clinical manifestations of vasculitis in these patients. METHODS: Using the PubMed database and search engine, we performed a search of the English-language literature by combining the term influenza vaccination with each term for a specific form of vasculitis from January 1966 through April 2016...

BACKGROUND: Eosinophilic granulomatosis with polyangiitis is an eosinophilic vasculitis. Mepolizumab, an anti-interleukin-5 monoclonal antibody, reduces blood eosinophil counts and may have value in the treatment of eosinophilic granulomatosis with polyangiitis. METHODS: In this multicenter, double-blind, parallel-group, phase 3 trial, we randomly assigned participants with relapsing or refractory eosinophilic granulomatosis with polyangiitis who had received treatment for at least 4 weeks and were taking a stable prednisolone or prednisone dose to receive 300 mg of mepolizumab or placebo, administered subcutaneously every 4 weeks, plus standard care, for 52 weeks...

Atypical hemolytic uremic syndrome (aHUS) is a rare disease characterized by hemolysis, thrombocytopenia, and renal failure. It is related to genetic mutations of the alternative complement pathway and is difficult to differentiate from other prothrombotic microangiopathies. Eosinophilic granulomatosis with polyangiitis (EGPA) (Churg-Strauss syndrome, CSS) is a systemic ANCA-associated vasculitis and a hypereosinophilic disorder where eosinophils seem to induce cell apoptosis and necrosis and therefore, vasculitis...

Non-infectious aortitis may be caused by several distinct systemic rheumatologic diseases. In some patients, aortitis is identified either pathologically or radiologically in the absence of clinical evidence of a systemic vasculitis. By consensus nomenclature, such cases are referred to as clinically isolated aortitis (CIA). Some systemic disorders may initially present as CIA including giant cell arteritis (GCA), IgG4-related disease, infectious aortitis, and granulomatosis with polyangiitis. CIA most commonly occurs in women of European descent over the age of 50 and, thus, mirrors the gender, age, and geographic distribution of GCA...

Eosinophils are multifunctional granulocytes that contribute to initiation and modulation of inflammation. Their role in asthma and parasitic infections has long been recognized. Growing evidence now reveals a role for eosinophils in autoimmune diseases. In this review, we summarize the function of eosinophils in inflammatory bowel diseases, neuromyelitis optica, bullous pemphigoid, autoimmune myocarditis, primary biliary cirrhosis, eosinophilic granulomatosis with polyangiitis, and other autoimmune diseases...

Granulomatosis with polyangiitis (GPA, Wegener granulomatosis) is a systemic autoimmune vasculitis that affects small arteries, arterioles, and capillaries, most notably in the kidneys and lungs. In this disease, proteinase 3 (PR3), produced by neutrophils, is targeted by antineutrophil cytoplasmic antibodies (ANCA). Recent work by our group has shown how PR3 impairs the resolution of inflammation and deregulates the immune system. Normally, the clearance of activated neutrophils triggers an anti-inflammatory, pro-resolution process...

PURPOSE OF REVIEW: Immunosuppressive therapy for connective tissue diseases (CTDs) is steadily becoming more intense. The resultant impairment in cell-mediated immunity has been accompanied by an increasing risk for opportunistic infection (OI). Pneumocystis pneumonia (PCP) has been recognized as an OI in patients with CTDs, but specific risk factors and precise indications for PCP prophylaxis remain poorly defined. This review was undertaken to update information on the risk of PCP in patients with CTDs and to examine current guidelines for PCP prophylaxis in this population...

A 41-year-old woman presented to her primary doctor with nausea, back pain and lower extremity oedema. Initial labs showed elevated serum creatinine and white blood cell count (WBC), which her doctor attributed to ibuprofen use and a recent upper respiratory infection. Five days later, she presented to the eye clinic with eye pain, redness and blurred vision. She was diagnosed with iritis, conjunctivitis and keratitis. The inflammatory eye disease with decreased renal function prompted the ophthalmologist to initiate systemic autoimmune and infectious disease work-up...

Anti-neutrophil cytoplasmic antibodies (ANCA) vasculitides are immune-mediated disorders that primarily affect small blood vessels of the airway and kidneys. Lung involvement, one of the hallmarks of microscopic polyangiitis and granulomatosis with polyangiitis, is associated with increased mortality and morbidity. In recent years, several retrospective series and case reports have described the association of interstitial lung disease (ILD) and ANCA vasculitis, particularly those positive for ANCA specific for myeloperoxidase...

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides are rare systemic diseases that usually occur in adulthood. They comprise granulomatosis with polyangiitis (GPA, Wegener's), microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (EGPA, Churg-Strauss syndrome). Their clinical presentation is often heterogeneous, with frequent involvement of the respiratory tract, the kidney, the skin and the joints. ANCA-associated vasculitis is rare in childhood but North-American and European cohort studies performed during the last decade have clarified their phenotype, patterns of renal involvement and their prognostic implications, and outcome...

OBJECTIVE: To determine the magnitude of all-cause mortality risk in patients with antineutrophil cytoplasmic antibodies-associated vasculitis (AAV) compared with the general population through a meta-analysis of observational studies. METHODS: We searched Medline and Embase databases from their inception to April 2015. Observational studies that met the following criteria were assessed by two researchers: (1) clearly defined AAV identified by either the American College of Rheumatology 1990 classification criteria or the 2012 Chapel Hill Consensus Conference disease definitions, and (2) reported standardised mortality ratios (SMR) and 95% CI...
