Epidemiological studies in AAV are important in understanding possible aetiologic mechanisms and facilitating healthcare planning. However, epidemiological studies present a number of challenges including clear definition of cases differentiated from other clinical disorders, and identification of cases due to the rarity of AAV. The aim of this review is to summarize different aspects on the epidemiology of ANCA-associated vasculitis from different geographical areas throughout the world. During the past three decades, development of classification criteria worldwide, including the ACR classification of 1990, the Chapel Hill consensus definitions updated in 2012 and the EMA algorithm has facilitated epidemiology studies in AAV. The available epidemiological studies reported in AAV suggest that incidence and prevalence may have increased over the past 30 years. Possible explanations for this increase may be a genuine increase in incidence, the evolution of classification criteria and the definition, and availability and wider use of ANCA serology to aid diagnosis, and greater physician awareness through education. The age-specific incidence for the whole group of AAV showed a clear increase with age. However, there has been a clear shift in the peak age at onset towards a higher age during the last 20-30 years. In addition, variation in incidence of AAV between men and women has been clearly evident in a number of epidemiological studies. © The Author(s) 2020.

Autoantibodies can be detected in all forms of primary small vessel vasculitis as well as in the most common forms of secondary vasculitis. For primary vasculitis the most important serological test is for ANCA. ANCA can be found in 75-95% of patients with pauci-immune small vessel vasculitis leading to this subgroup of vasculitides being named ANCA associated vasculitis. ANCA levels often follow this disease course, but the value of serial ANCA testing is controversial. Other important autoantibodies in primary small vessel vasculitis are anti-glomerular basement membrane antibodies, anti-C1q, anti-galactose deficient IgA and cryoglobulins. A wide variety of systemic inflammatory diseases and infections can be complicated by small vessel vasculitis and detected by serological testing. Important examples are SLE, rheumatoid arthritis, Hepatitis C and HIV. © The Author(s) 2020. Published by Oxford University Press on behalf of the British Society for Rheumatology.

A key feature of AAV is the presence of Anti-Neutrophil Cytoplasmic Antibodies (ANCA) directed against myeloperoxidase (MPO) or proteinase-3 (PR3). ANCA are key to the pathogenesis of AAV, where they activate innate immune cells to drive inflammation. Pre-activation or 'priming' of immune cells appears to be important for complete cellular activation in AAV. The burgeoning field of immunometabolism has illuminated the governance of immune cell function by distinct metabolic pathways. There is ample evidence that the priming events synonymous with AAV alter immune cell metabolism. In this review we discuss the pathogenesis of AAV and its intersection with recent insights into immune cell metabolism. © The Author(s) 2020.

With current management strategies, such as high-dose glucocorticoids in combination with cyclophosphamide or rituximab, outcomes have progressively improved with overall remission rates of 70-90%. However, relapse rates after discontinuation of therapy are consistently high, and treatment-related toxicity, mainly driven by glucocorticoids, still determines morbidity and quality of life. Prevention of relapses while minimizing adverse events is a major goal of long-term treatment, but the optimal duration of maintenance therapy and the role and utility of glucocorticoids in this context remains controversial. This review of induction and maintenance treatment of AAV aims to offer practical advice on immunosuppressive therapies and patient care, addressing individual risk factors and their therapeutic implications. It will discuss benefits and harms of the use of glucocorticoids, particularly focusing on recent advances in steroid sparing concepts. © The Author(s) 2020.

Recent research has focused on complications of immunosuppressive measures and comorbidities of ANCA-associated vasculitis. This review focuses on thromboembolic and cardiovascular events. A considerably increased risk of thromboembolic events has been reported, which is associated with active disease and impaired coagulation factors. There is mounting evidence that a hypercoagulable state is present even in patients in remission, and studies investigating the impact of tailored anticoagulation are needed to reduce the burden of thromboembolism. Cardiovascular mortality is one of the leading causes of death and accelerated atherosclerosis is frequently observed in patients with ANCA-associated vasculitis. A high frequency of patients develops hypertension, diabetes mellitus and hypercholesterolaemia, either as a consequence of immunosuppression or associated with the underlying disease.
