Anti-neutrophil cytoplasmic antibodies (ANCAs) are valuable laboratory markers used for the diagnosis of well-defined types of small-vessel vasculitis, including granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA). According to the 1999 international consensus on ANCA testing, indirect immunofluorescence (IIF) should be used to screen for ANCAs, and samples containing ANCAs should then be tested by immunoassays for proteinase 3 (PR3)-ANCAs and myeloperoxidase (MPO)-ANCAs. The distinction between PR3-ANCAs and MPO-ANCAs has important clinical and pathogenic implications...

OBJECTIVE: Neutrophil extracellular traps (NETs) are peculiar structures composed of the externalized chromatin with intracellular proteins and formed by activated neutrophils in a reactive oxygen species (ROS)-dependent manner. Aberrant NETs are considered to be autoantigens for anti-neutrophil cytoplasmic antibodies (ANCAs) underling the development of microscopic polyangiitis (MPA). However, little is known regarding the therapeutic efficacy of in vivo inhibition of NET formation (NETosis) on MPA pathogenesis...

Idiopathic myointimal hyperplasia of mesenteric veins causes chronic ischemic mucosal injury with segmental strictures that mimic inflammatory bowel disease and nonocclusive ischemic colitis. It is characterized by myointimal proliferative changes that narrow the lumina of veins combined with ischemic injury and ulcers. Most cases reported to date have been diagnosed following surgical resection. The aim of this study was to determine whether mucosal changes of idiopathic myointimal hyperplasia of mesenteric veins are sufficiently sensitive and specific to allow its recognition in biopsy material...

BACKGROUND: Henoch-Schonlein purpura (HSP) is a systemic small-vessel vasculitis that occurs mainly in children. A review of the literature has suggested a correlation between mean platelet volume (MPV) and several inflammatory disorders. However, to the best of our knowledge, any potential correlation between MPV and HSP has not been reported in the literature. Therefore, our study aimed to evaluate the role of MPV levels in patients with HSP. METHODS: This study included 97 children with HSP and 120 healthy individuals as controls...

Cutaneous small-vessel vasculitis (CSVV) is an infrequent manifestation of pediatric inflammatory bowel disease (IBD). We report two cases of CSVV associated with ulcerative colitis, review the literature, and discuss the diagnostic evaluation of children who present with CSVV and abdominal pain. After excluding more common causes of CSVV and abdominal pain in children, including immunoglobulin A vasculitis (previously Henoch-Schönlein purpura), infectious colitis, and drug-induced vasculitis, alternative diagnoses such as CSVV secondary to IBD or systemic vasculitis with gastrointestinal involvement must be considered...

Eosinophilic granulomatosis with polyangiitis (EGPA), formerly known as Churg-Strauss syndrome (CSS), is a small vessel vasculitis associated with eosinophilia and asthma. Clinical manifestations commonly seen in patients presenting with EGPA range from upper airway and lung involvement to neurological, cardiac, cutaneous, and renal manifestations. Treatment for severe presentations includes steroids, cyclophosphamide, plasmapheresis, and recently, rituximab. Rituximab is associated with a good response in the treatment of vasculitis, but a variable response for the control of allergic symptoms...

Immunoglobulin A (IgA) vasculitis is the most common leukocytoclastic small-vessel vasculitis in children and mainly involves the small vessels in the skin, joints, digestive tract, and kidneys. Its pathogenesis is still unclear. Currently, it is believed that environmental factors can cause autoimmune dysfunction and lead to the deposition of IgA-containing immune complexes on the wall of arterioles on the basis of genetic factors. This article reviews the research advances in the role of immune factors in the pathogenesis of IgA vasculitis...

Hydralazine-induced small vessel vasculitis is a rare entity with a limited number of cases reported in the dermatologic literature. A characteristic pattern of acral pseudoembolic vesiculopustules with necrosis and ulceration has been suggested along with involvement of the aerodigestive tract, indicating mucosal involvement is an important feature of this disease. We report the case of a patient with hydralazine-induced vasculitis who exemplified this characteristic presentation associated with severe involvement of the aerodigestive tract and gastrointestinal tract bleeding...

Vasculitides comprise several diseases affecting vessels of different sizes, mainly arteries, but also capillaries and veins. Antineutrophil cytoplasm antibody-associated vasculitides (AAVs) belong to the systemic necrotizing small-vessel vasculitis group that comprises granulomatosis with polyangiitis, microscopic polyangiitis and eosinophilic granulomatosis with polyangiitis. Internists often see AAV patients, and although their outcomes are usually good, the disease can be responsible for morbidity and mortality...

Neuro-Behcet's disease (NBD) is a rare neurological manifestation of the systemic small vessel vasculitis called Behcet's disease. It can present in various ways with predilection for the brain stem, thalamo- hypothalamic regions, cerebellum and basal ganglia. In this case, we describe a case of young stroke that was later attributed to NBD.

Henoch-Schönlein purpura (HSP) is the most common form of systemic small-vessel vasculitis in children, and HSP nephritis (HSPN) is a major complication of HSP and is the primary cause of morbidity and mortality. Previous studies have suggested that inducible nitric oxide synthase (iNOS) may play an important role in the pathogenesis of HSP. In this study, we performed a detailed analysis to investigate the potential association between iNOS polymorphisms and the risk of HSP and the tendency for children with HSP to develop HSPN in a Chinese Han population...

Leukocytoclastic vasculitis (LCV) is a cutaneous small vessel vasculitis characterized by cutaneous manifestations in the form of palpable purpura, and rarely bullae, vesicles, and ulcerations. Although rare, cephalosporins such as cefazolin, should be recognized to have a potential to trigger LCV.

Skin lesions are frequent manifestations of underlying systemic conditions, including systemic autoimmune vasculitis. In particular, anti-neutrophil cytoplasmic antibodies (ANCA) are associated with distinct forms of vasculitis characterized by inflammatory cell infiltration of the walls of small and medium-sized vessels leading to vascular destruction and tissue necrosis. ANCA-associated vasculitis is rare and systemic diseases, which can be classified based on different distribution of vascular inflammation and presence or absence of granulomatosis and asthma...

Microscopic polyangiitis (MPA) is a small vessel multisystemic disorder characterised by necrotising small vessel vasculitis without any immune deposits. Kidney and lung are the predominant organs affected in MPA. Skin, gastrointestinal and neurological findings are also described. Isolated pulmonary manifestations are rare. The authors describe a two-year girl who presented with right heart failure and was subsequently diagnosed as ANCA-associated vasculitis. This case report is intended to sensitise pediatricians to consider systemic vasculitis with pulmonary hemorrhage in children with pulmonary hypertension even in the absence of severe pallor...

BACKGROUND: Microscopic polyangiitis (MPA), which is classified as an anti-neutrophil cytoplasmic antibody (ANCA)-associated small vessel vasculitis, is one of the most frequent primary vasculitides in Japan. We earlier nominated 16 genes (IRF7, IFIT1, IFIT5, OASL, CLC, GBP-1, PSMB9, HERC5, CCR1, CD36, MS4A4A, BIRC4BP, PLSCR1, DEFA1/DEFA3, DEFA4, and COL9A2) as predictors of response to remission induction therapy against MPA. The aim of this study is to determine the accuracy of prediction using these 16 predictors...

Systemic vasculitis is a rare but severe group of diseases characterized by inflammation and necrosis of blood vessels. The size of the vessel affected varies among the different forms of vasculitis and there are three main subgroups: large, medium and small vessel vasculitis. Among small vessel vasculitis, the antineutrophil cytoplasmic antibody (ANCA)-associated forms are of particular importance. This subgroup includes: microscopic polyangiitis, granulomatosis with polyangiitis (Wegener's), eosinophilic granulomatosis with polyangiitis (Churg-Strauss) and the form limited to the kidney...

PURPOSE: Granulomatosis with polyangiitis (GPA) is a multisystem disease, characterized by necrotizing small-vessel vasculitis, which mainly affects the respiratory tract and the kidneys. Pituitary involvement in GPA is rare, present in about 1% of all cases of GPA. To date, only case reports or small case series have been published. Herein we report clinical features, imaging findings, treatment and outcomes in three patients with GPA-related pituitary dysfunction (PD). METHODS: A retrospective analysis of three cases of GPA-related PD was conducted, followed by systematic review of the English medical literature using PubMed...
