Rheumatic disorders comprise a number of diseases that range from benign, mildly symptomatic degenerative disease to severe systemic disorders such as giant-cell vasculitis with dramatic consequences such as acute blindness. The former is relatively common, whereas the latter is rare. In between, commonly encountered disorders such as rheumatoid arthritis and the various spondyloarthritides, with or without peripheral enthesitis, are daily challenges for the caring physician. Clinical evaluation is of utmost importance and is constantly described under the form of specialist guidelines in all parts of the world...

Anti-neutrophil cytoplasmic antibodies (ANCA) play a central role in the diagnostic and pathogenesis of patients with small vessel vasculitis, so called ANCA-associated vasculitis (AAV). ANCA in these diseases are almost always directed against proteinase 3 (PR3-ANCA) and myeloperoxidase (MPO-ANCA). Most laboratories worldwide use as standard the indirect immunofluorescence technique (IFT), on human neutrophils, to screen for ANCA, and then confirm positive IFT results with antigen specific immunoassyas for PR3- and MPO-ANCA...

Kawasaki disease is an acute vasculitis of early childhood. Its incidence varies among different ethnic groups with higher rates among Asians. In this case series, we presented four cases of Kawasaki disease with incomplete or atypical presentations in Egyptian children. Two cases presented with meningitis, which is not a criteria for the diagnosis of Kawasaki disease. The other two cases presented with pharyngitis and fever, which did not respond to antibiotics. The clinical criteria for diagnosis of Kawasaki disease were either incomplete or appeared sequentially...

IgG4-related disease is a heterogeneous immune-mediated fibroinflammatory condition that can affect every single organ. This disease is more prevalent in the elderly (the mean age of patients is above 60 years) and the prevalence rate is estimated to be over 4.6 per 100,000 population. Before making a diagnosis, the exclusion of malignancies, lymphoma, anti-neutrophil cytoplasmic antibody-associated vasculitis, multicentric Castleman disease, and other mimickers is crucial for appropriate treatment. Broad management guidelines have been published emphasizing the need for prompt treatment and the use of glucocorticoids as first-line drug therapy for induction of remission...

Testing for antineutrophil cytoplasmic antibodies (ANCA) is performed to diagnose or exclude small vessel vasculitis, and, in treated patients, to monitor disease activity. However testing is also undertaken to assist with the diagnosis of other autoimmune diseases and some infections. Most laboratories use the same assays for all sera regardless of the testing indications. The International Consensus Statement on ANCA Testing and Reporting recommended screening for ANCA by indirect immunofluorescence (IIF) and confirming IIF-positive sera in antigen-specific ELISAs for both proteinase 3 (PR3) and myeloperoxidase (MPO)...

Background: Current guidelines advise that rituximab or cyclophosphamide should be used for the treatment of organ-threatening disease in anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis (AAV), although few studies have examined the efficacy and safety of these agents in combination. Methods: We conducted a single-centre cohort study of 66 patients treated with a combination of oral corticosteroids, rituximab and low-dose pulsed intravenous cyclophosphamide followed by a maintenance regimen of azathioprine and tapered steroid for the treatment of biopsy-proven renal involvement in AAV...

Kawasaki disease (KD) is a common medium vessel systemic vasculitis that usually occurs in small children. It has a predilection for the coronary arteries, but other medium sized arteries can also be involved. The etiology of this disorder remains a mystery. Though typical presentation of KD is quite characteristic, it may also present as incomplete or atypical disease in which case the diagnosis can be very challenging. As both incomplete and atypical forms of KD can be associated with serious coronary artery complications, the pediatrician can ill afford to miss these diagnoses...

BACKGROUND: Kawasaki disease (KD) is a self-limited acute systemic vasculitis of unknown aetiology that predominantly affects infants and young children eventually associated with immunological abnormalities. Coeliac disease (CD) is an inflammatory autoimmune disease characterised by a permanent gluten intolerance, which affects genetically susceptible individuals of any age group, and can cause intestinal and systemic symptoms. Association of CD with KD has been previously described in a single study that disclosed a surprisingly high prevalence of CD in children with a history of KD...

The current practice for detection of anti-neutrophil cytoplasm antibodies (ANCA) directed against proteinase 3 (PR3) and myeloperoxidase (MPO) has been screening by indirect immunofluorescence (IIF) followed by an antigen specific tests for PR3- and MPO-ANCA. However, ANCA diagnostics have undergone many technical developments that have affected the 1999 international consensus recommendations, and lead to a revision of the existing ANCA detection strategy. Recent European multicentre studies have compared the diagnostic performance of various ANCA detection methods and demonstrated that PR3- and MPO-ANCA immunoassays yielded the highest diagnostic accuracy...

Kawasaki disease (KD) is a medium vessel vasculitis with predilection for coronary arteries. Due to lack of a reliable confirmatory laboratory test, the diagnosis of KD is based on a constellation of clinical findings that appear in a typical temporal sequence. These diagnostic criteria have been modified from time to time and the most recent guidelines have been proposed by the American Heart Association (AHA) in 2017. However, several children may have incomplete or atypical forms of KD and the diagnosis can often be difficult, especially in infants and young children...

Relapsing polychondritis (RPC) is a rare autoimmune rheumatic disorder that is traditionally classified as a systemic vasculitis. It is characterized by inflammation of cartilage, and typical presenting features include chondritis of the nasal bridge, auricular chondritis, ocular inflammation and involvement of the bronchial tree. Its rarity often leads to considerable delay in establishing a diagnosis and poses a significant management challenge to clinicians, as no conventional guidelines exist. This review summarizes the clinical features of RPC and provides guidance for rheumatologists on making the diagnosis and assessing organ involvement...

'Mind the gap' is a recorded warning phrase used in the London Tube since 1969. The following article is meant to be a warning of an increasing knowing-doing gap in routine practice of therapeutic plasma exchange (TPE), a treatment method that is used more and more throughout the world. The American Society of Apheresis recommendations, including the most recent ones from 2016, suggest using a TPE volume of 1.0-1.5 times the actual calculated plasma volume of the patient. There are only a few exceptions to that rule, such as the recommnded exchange volume in vasculitis or mushroom poisoning...

Objectives: Several chronic inflammatory diseases are associated with cardiovascular disease, but the risk in ANCA-associated vasculitis is poorly quantified. The aim of the present study was to review the evidence for an increased cardiovascular risk, including ischaemic heart disease, cerebrovascular accidents and peripheral arterial disease, in patients with ANCA-associated vasculitis. Methods: A comprehensive systematic review was conducted in accordance with guidelines of preferred reporting items for systematic reviews and meta-analyses...

The proposal by the 1994 International Chapel Hill Consensus Conference on the Nomenclature of Systemic Vasculitides (CHCC1994) and by the CHCC2012 markedly influenced the classification and way of considering cutaneous vasculitis. In the proposal by the CHCC1994, hypersensitivity angiitis was defined as an equivalent pathological condition to microscopic polyangiitis or cutaneous leukocytoclastic angiitis (CLA), and it was not adopted as a disease name. However, CLA which was positioned as a type of small-vessel vasculitis is only a pathological name...
