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...

BACKGROUND: Antineutrophil cytoplasmic antibody-associated vasculitis is triggered by environmental factors, including silica dust exposure. Repeated tsunami waves brought a large volume of silica-containing sludge inland after the Great East Japan earthquake in 2011. We aimed to determine if the serious disaster influenced the clinical features of the microscopic polyangiitis. METHODS: This is an observational retrospective study conducted in a single institute...

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...

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...

Recent findings have indicated a close relationship between myeloperoxidase antineutrophil cytoplasmic antibody (MPO-ANCA)-positive hypertrophic pachymeningitis and the limited form of granulomatosis with polyangiitis (GPA). In Japan, MPO-ANCA-positive hypertrophic pachymeningitis predominantly occurs in elderly individuals. We herein describe the cases of two patients with MPO-ANCA-positive hypertrophic pachymeningitis associated with the limited form of GPA who were successfully treated with a combination of corticosteroids and methotrexate...

OBJECTIVES: Inappropriate activation of neutrophils plays a pathological role in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). The aim of this study was to investigate the functions of semaphorin 4D (SEMA4D) in regulation of neutrophil activation, and its involvement in AAV pathogenesis. METHODS: Serum levels of soluble SEMA4D were evaluated by ELISA. Blood cell-surface expression of membrane SEMA4D was evaluated by flow cytometry. To determine the functional interactions between neutrophil membrane SEMA4D and endothelial plexin B2, wild-type and SEMA4D(-/-) mice neutrophils were cultured with an endothelial cell line (MS1) stained with SYTOX green, and subjected to neutrophil extracellular trap (NET) formation assays...

Two children with congenital heart disease status post surgical correction presented with prolonged constitutional symptoms, hepatosplenomegaly and pancytopenia. Concern for malignancy prompted bone marrow biopsies that were without evidence thereof. In case 1, echocardiography identified a multilobulated vegetation on the conduit valve. In case 2, transthoracic, transesophageal and intracardiac echocardiography were performed and were without evidence of cardiac vegetations; however, pulmonic emboli raised concern for infective endocarditis...

Levamisole (an increasingly frequent contaminant of cocaine) can cause antineutrophil cytoplasmic antibody-associated vasculitis. Dermatologists should consider a diagnosis of cocaine/levamisole-associated cutaneous vasculopathy syndrome in cases of purpura of the ears and/or extensive retiform purpura in drug users. We report a case of particularly severe levamisole-induced necrotic purpura and immunological abnormalities in a 40-year-old woman.

A 66-year-old man presented with headache and ophthalmalgia. Diplopia developed, and he was hospitalized. The left eye had abducent paralysis and proptosis. We diagnosed him with Tolosa-Hunt syndrome and administered methylprednisolone at 1 g/day for 3 days. However, the patient did not respond to treatment. No abnormality was found on his MRI or cerebrospinal fluid examination. Tests showed his serum immunoglobulin G4 and antineutrophil cytoplasmic antibody titers were within normal limits. He also had untreated diabetes mellitus (HbA1c 9...

Microscopic polyangiitis is an uncommon systemic vasculitis of varying severity that is associated with myeloperoxidase (MPO) and perinuclear antineutrophil cytoplasmic (p-ANCA) antibodies. The most commonly affected organs are the lungs and kidneys. We report on a very unusual case of microscopic polyangiitis presenting with severe mesenteric ischemia in addition to diffuse alveolar hemorrhage and acute renal failure. The patient was initially diagnosed with acute pancreatitis at an outside facility given his severe abdominal pain and elevated pancreatic enzymes...

This paper describes one patient with Antineutrophil Cytoplasmic Antibody- (ANCA-) associated vasculitis who initially presented with multiple ischemic fingers and toes. On further evaluation, the patient was also found to have pulmonary-renal involvement and episcleritis. The diagnosis was supported with a positive cANCA (anti-proteinase 3) and a bronchoscopy consistent with diffuse alveolar hemorrhage. Although the patient refused a tissue biopsy, clinical presentation including nasal ulceration, sinus congestion, and epistaxis and anti-proteinase 3 antibody were more consistent with Granulomatosis with Polyangiitis (GPA) rather than Microscopic Polyangiitis (MPA) or Eosinophilic Granulomatosis with Polyangiitis (EGPA) based on the recently presented ACR/EULAR Provisional 2017 Classification Criteria for GPA (Luqmani et al...

Eosinophilic granulomatosis with polyangiitis (EGPA), formerly known as Churg-Strauss syndrome, is a rare systemic disease situated between primary small vessel vasculitides associated with antineutrophil cytoplasmic antibodies (ANCAs) and hypereosinophilic syndromes (HES). Here, we present a case of EGPA in a 38-year-old male, with a previous diagnosis of asthma, who presented with fever, migratory lung infiltrates and systemic eosinophilia that was refractory to previous courses of antibiotics. This case highlights the importance of the primary care physician understanding the differential diagnosis of pulmonary eosinophilic syndromes...
