Skull base osteomyelitis in the setting of granulomatosis with polyangiitis (GPA) is rare and entails significant diagnostic challenges. We present a case of a 65-year-old Caucasian man with a history of rheumatoid arthritis, off immunosuppression for 18 months, who presented with 2 years of chronic headaches, severe fatigue, saddle nose deformity and 20-kilogram unintentional weight loss. Maxillofacial CT revealed an extensive destructive sinonasal and erosive skull base process. Laboratory evaluation showed equivocal elevation of antiproteinase 3 antibodies with negative antineutrophil cytoplasmic antibody panel...

In patients with severe aortic stenosis (AS), the presence of pulmonary hypertension (PH) has been linked to a poor prognosis. We aimed to assess the main determinants of PH in patients with severe AS and preserved left ventricular ejection fraction (LVEF). We prospectively enrolled 108 consecutive patients with isolated severe AS (indexed aortic valve area <0.6 cm(2)/m(2)) and LVEF >50%, in sinus rhythm. Left atrial (LA) function was assessed using longitudinal deformation parameters (by speckle tracking echocardiography)...

The synovium is the major target tissue of inflammatory arthritides such as rheumatoid arthritis. The study of synovial tissue has advanced considerably throughout the past few decades from arthroplasty and blind needle biopsy to the use of arthroscopic and ultrasonographic technologies that enable easier visualization and improve the reliability of synovial biopsies. Rapid progress has been made in using synovial tissue to study disease pathogenesis, to stratify patients, to discover biomarkers and novel targets, and to validate therapies, and this progress has been facilitated by increasingly diverse and sophisticated analytical and technological approaches...

INTRODUCTION: During year 2013, 5943 tests for antineutrophil cytoplasmic antibodies (ANCA) detection were performed in Bordeaux hospital, France. This seemed disproportionate, with regard to the low prevalence of ANCA-associated vasculitis (AAV). Our purpose was to evaluate the relevance of these requests. METHODS: Requests for detection of ANCA during 2013 were recorded, with their results. A sample of 501 requests was secondarily established. Relevance of requests was assessed independently by two reviewers...

BACKGROUND: Influenza-associated deaths is an important risk for the elderly in nursing homes (NHs) worldwide. Vaccination coverage among residents is high but poorly effective due to immunosenescence. Hence, vaccination of personnel is an efficient way to protect residents. Our objective was to quantify the seasonal influenza vaccination (IV) coverage among NH for elderly workers and identify its determinants in France. METHODS: We conducted a cross-sectional study in March 2016 in a randomized sample of NHs of the Ille-et-Vilaine department of Brittany, in western France...

OBJECTIVE: Granulomatosis with polyangiitis (GPA) that is localized to the upper airway presents a diagnostic challenge because of a tendency towards anti-neutrophil cytoplasmic antibody (ANCA)-negativity. The purpose of this study was to investigate whether positivity of ANCA detection might be elicited with combined use of enzyme-linked immunosorbent assay (ELISA) kits. METHODS: Twenty-nine serum samples obtained from GPA patients were used in this study. In addition to routine biochemical investigation for ANCA, tests for detecting PR3-, MPO-ANCAs, and minor ANCAs were performed with commercially available ELISA kits...

Cocaine abuse occasionally causes extensive destruction of the osteocartilaginous structures of the nose, sinuses and palate, which mimics the clinical picture of other diseases associated with necrotising midfacial lesions. The differentiation of cocaine-induced midline destructive lesions (CIMDL) and limited granulomatosis with polyangiitis (GPA) may be difficult, particularly if patients do not readily admit substance abuse. We studied 10 patients with CIMDL and palate perforation referred to our Unit between 2002 and 2015...

BACKGROUND: Data on serum antibodies in untreated adult inflammatory bowel disease (IBD) patients at diagnosis are scarcely available, and results on the stability of antibody presence over time are inconsistent. Our aim was to investigate antibodies in newly diagnosed, untreated IBD patients in relation to disease phenotype and course. Furthermore, we analyzed antibody presence over time. METHODS: Baseline anti-Saccharomyces cerevisiae antibodies (ASCA), anti-chitobioside carbohydrate antibodies (ACCA), anti-laminaribioside carbohydrate antibodies (ALCA) and anti-mannobioside carbohydrate antibodies (AMCA) were measured with enzyme-linked immunosorbent assays and perinuclear anti-neutrophilic cytoplasmic antibodies (pANCA) was measured by indirect immunofluorescence in serum of 120 untreated IBD patients at diagnosis and 19 healthy controls...

Flavonoids, natural compounds found in plants and in plant-derived foods and beverages, have been extensively studied with regard to their capacity to modulate metabolic enzymes and drug transporters. In vitro, flavonoids predominantly inhibit the major phase I drug-metabolizing enzyme CYP450 3A4 and the enzymes responsible for the bioactivation of procarcinogens (CYP1 enzymes) and upregulate the enzymes involved in carcinogen detoxification (UDP-glucuronosyltransferases, glutathione S-transferases (GSTs))...

CONTEXT: The neural cell adhesion molecule CD56 is an antigen important for the differentiation of the follicular epithelium. Recent studies have reported low or absent expression of CD56 in papillary thyroid carcinoma (PTC) and its presence in normal thyroid tissue, benign thyroid lesions, and most follicular non-PTC tumors. AIM: We wish to estimate the value of CD56 in the differentiation of PTC (including follicular variant-PTC [FV-PTC]) from other nontumoral lesions and follicular thyroid neoplasias...

PURPOSE OF REVIEW: To understand the clinical spectrum of cocaine-levamisole-induced vasculitis. Worldwide recreational drug consumption is high among the adult population from various social strata. The use of cocaine with levamisole, a frequently added antiparasitic diluent, favors the manifestations of vasculitic lesions, especially in the skin. RECENT FINDINGS: New insights into immunological mechanisms involved in the pathogenesis of the disease. There are still many unknown aspects in the pathogenesis of this disease, such as the immune system interaction with p-ANCAs and the release of inflammatory NETs (neutrophil extracellular traps), which are the origin of auto-antigens and tissue damage, manifesting as vasculitic purpura on the skin...

BACKGROUND: Perinuclear antineutrophil cytoplasmic antibodies (pANCA) previously have been shown to be serum markers in dogs with chronic enteropathies, with dogs that have food-responsive disease (FRD) having higher frequencies of seropositivity than dogs with steroid-responsive disease (SRD). The indirect immunofluorescence (IIF) assay used in previous publications is time-consuming to perform, with low interobserver agreement. HYPOTHESIS/OBJECTIVES: We hypothesized that a commercially available granulocyte IIF assay designed for humans could be used to detect perinuclear antineutrophil cytoplasmic antibodies in dogs...

OBJECTIVES: Cardiovascular disease, including myocardial infarction and stroke, is a major cause of mortality in ANCA-associated vasculitis (AAV). Although AAV affects small vessels, an accelerated atherosclerosis not explained by traditional cardiovascular risk factors (CVRF) has been demonstrated. We aimed to investigate the association of atherosclerosis measured by carotid intima-media thickness (CIMT) and cerebral small vessel disease in AAV-patients. MATERIALS & METHODS: Twenty-three AAV-patients in complete remission were recruited...

BACKGROUND Levamisole is a common adulterant of cocaine. It can cause agranulocytosis and cutaneous vasculitis that can possibly lead to cutaneous necrosis. In all reported cases of levamisole-induced vasculitis, it has been described as a clinical syndrome characterized by a constellation of typical clinical features and a positive serum serology for ANCA levels, especially very high-titer p-ANCA levels, in the background of cocaine abuse. However, patients may have a negative serology and here, we present the first such case...

BACKGROUND: Relapse of disease is frequent in anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis (AAV). It is unclear whether persistent ANCA when starting maintenance therapy increases the risk of relapse. We examined the association between ANCA status and relapse in two randomised controlled trials. METHODS: ANCA-positive patients in two trials, CYCLOPS and IMPROVE, were switched from cyclophosphamide to maintenance therapy after achieving clinical remission...
