IgA vasculitis is a small-vessel vasculitis mediated by immune complexes. In clinical terms, it is characterized by palpable purpura in the lower limbs, joint involvement in the form of arthralgia or arthritis, and gastrointestinal and renal involvement (this will mark a poorer prognosis in adults). Infectious processes, mainly in the upper respiratory tract, are frequently found to be triggers. On the other hand, human immunodeficiency virus (HIV) causes immune dysfunction, which triggers hypergammaglobulinemia and can trigger autoimmune disorders...

BACKGROUND: Henoch-Schönlein purpura is a common small vessel vasculitis in children. Acute pancreatitis rarely presents as a complication of Henoch-Schönlein purpura and has not been well characterized. METHODS: We retrospectively reviewed 13 cases of Henoch-Schönlein purpura with acute pancreatitis among 3212 patients who attended our hospital between January 2003 and June 2016 and analyzed their clinical characteristics, laboratory findings, imaging findings, treatment and overall prognosis...

Granulomatosis with polyangiitis (GPA) is a systemic necrotizing small vessel vasculitis associated with circulating anti-neutrophil cytoplasmic antibodies (ANCAs). Skin manifestations, mostly represented by palpable purpura, papulonodular lesions and livedo reticularis, are present in up to 50% of the cases. Ulcerations with undermined, raised erythematous-violaceous border resembling pyoderma gangrenosum (PG) have rarely been reported as skin involvement in GPA. The presence of circulating ANCAs with a cytoplasmic labelling pattern, the involvement of internal organs, particularly of the lung, and the absence on histology of a mainly neutrophilic infiltrate in early phases of the cutaneous lesions may be regarded as clues to rule out true PG and confirm the diagnosis of GPA skin ulcerations simulating PG...

Anti-neutrophil cytoplasmic autoantibodies (ANCA) targeting proteinase 3 (PR3) and myeloperoxidase expressed by innate immune cells (neutrophils and monocytes) are salient diagnostic and pathogenic features of small vessel vasculitis, comprising granulomatosis with polyangiitis (GPA), microscopic polyangiitis, and eosinophilic GPA. Genetic studies suggest that ANCA-associated vasculitides (AAV) constitute separate diseases, which share common immunological and pathological features, but are otherwise heterogeneous...

Granulomatosis with polyangiitis (GPA) is known as anti-neutrophil cytoplasmic antibody- (ANCA-) associated small vessel vasculitis and typically manifests as pulmonary-renal syndrome, but the disease is not limited to pulmonary or renal systems. The inflammation can involve whole body organs. In addition, the ANCA titer does not always become positive. Here, we describe the case of a 91-year-old man who presented with umbilical pain and fever of unknown origin. Only the increased computed tomography value of the greater omentum suggested intra-abdominal inflammation; however, serological examinations, including the ANCA level, could not reveal the focus or cause of symptoms...

BACKGROUND: Granuloma faciale (GF), or facial granuloma of Lever, is an uncommon dermatosis occurring classically on the face. We report a case of a GF on zoster scars located on the trunk, which is a highly particular isotopic response. PATIENTS AND METHODS: A 60-year-old man with a sole history of left lumbar zoster presented with a skin lesion present for two months. Clinical examination revealed a 2.5-cm papular erythematous lesion that was both infiltrated and pruritic...

Skin is commonly affected by vasculitic process and often subjected to biopsy. Cutaneous vasculitis can be either primary or part of a systemic vasculitic process. This study was conducted to evaluate the diagnostic utility of direct immunofluorescence (DIF) in determination of etiology of cutaneous vasculitis. All histologically proven cases of cutaneous vasculitis over the past two and half years were retrospectively analyzed along with their clinical and DIF findings (IgG, IgA, IgM, and C3). Within this study period, a total of 198 cases of small-vessel vasculitis were diagnosed based on skin biopsy and DIF findings...

Background: Brucellosis is an important multisystemic disease with many different clinical symptoms, and its early diagnosis and treatment are possible. Neurobrucellosis (NB) is a rare but serious finding of brucellosis. Brucella can be seen as meningitis and encephalopathy, and it can cause cranial nerve pathologies, vascular syndromes, myopathy, spinal diseases, and psychiatric disorders. In NB, vascular syndromes secondary to inflammation are rarely seen. Here, we present nine young patients with vascular and nonspecific neuropsychiatric findings who had NB as the etiology of stroke...

BACKGROUND/OBJECTIVE: Several studies have identified predictors of relapse in antineutrophil cytoplasmic antibody-associated small-vessel vasculitis. However, the role of smoking as a risk factor of relapse has not been elucidated. Therefore, this study aimed to evaluate whether a history of smoking is a dose-dependent independent risk factor for antineutrophil cytoplasmic antibody-associated small-vessel vasculitis relapse. METHODS: This multicenter retrospective cohort study included 122 patients with granulomatosis with polyangiitis and microscopic polyangiitis (MPA) from 9 nephrology centers in Japan...

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...

NKT cells belong to a distinct subset of T cells that recognize hydrophobic antigens presented by major histocompatibility complex class I-like molecules, such as CD1d. Because NKT cells stimulated by antigens can activate or suppress other immunocompetent cells through an immediate production of a large amount of cytokines, they are regarded as immunological modulators. CD1d-restricted NKT cells are classified into two subsets, namely, type I and type II. CD1d-restricted type I NKT cells express invariant T cell receptors (TCRs) and react with lipid antigens, including the marine sponge-derived glycolipid α-galactosylceramide...

Systemic urticaria in a 64-year-old woman was diagnosed as leukocytoclastic vasculitis by a punch biopsy of the skin. Her physical findings improved after prescription of prednisolone at a dose of 20 mg/day, but the skin rash relapsed with renal dysfunction, proteinuria, and hematuria when the dose of prednisolone was reduced over a period of 9 months to 1 mg/day. She was admitted to our institute for further examination, when urinary protein and plasma creatinine levels were 0.8 g/day and 1.7 mg/dL, respectively...

Immunoglobulin A associated vasculitis (IgAV), formerly called Henoch-Schönlein purpura, is a small vessel vasculitis which typically presents with upper and lower extremity palpable purpura and abdominal pain. It is the most common vasculitis in children, and is less common in adults. However, newer evidence suggests the incidence within the adult population is higher than previously reported. This case study demonstrates an adult military recruit presenting with new onset IgAV shortly after basic training...

Varicella zoster virus (VZV) vasculopathy was initially described as herpes zoster ophthalmicus with contralateral hemiplegia in 1896. VZV is able to infect endothelial cells directly, leading to a thickened intima and vascular remodeling due to inflammation. Therefore, a spectrum of vasculopathies is induced, ranging from a discrete capillaritis-to-granulomatous vasculitis and obliterative angiitis. Cutaneous vasculitic changes sui generis with leukocytoclasia, cell debris, vascular damage, and endothelial swelling are very rare feature of herpetic infections in skin biopsies...

Background: Eosinophilic granulomatosis with polyangiitis (EGPA) is an antineutrophil cytoplasmic antibody- (ANCA-) associated small vessel vasculitis with multisystem involvement. It is characterized with asthma, eosinophilia, and renal and peripheral nervous system involvement. However, EGPA presenting with bullous skin eruption is an uncommon dermatological manifestation. We report a rare case of EGPA overlapped with mixed essential cryoglobulinemia presenting with a bullous skin eruption...

Anti-neutrophil cytoplasmic antibodies (ANCA) are a group of autoantibodies that cause systemic vascular inflammation by binding to target antigens of neutrophils. These autoantibodies can be found in serum from patients with systemic small-vessel vasculitis and they are considered as a biomarker for ANCA-associated vasculitis (AAV). A conventional screening test to detect ANCA in the serum is indirect immunofluorescence study, and subsequently confirmed by enzyme-linked immunosorbent assay. A positive staining of ANCA can be classified into three main categories based on the staining patterns: cytoplasmic, perinuclear, and atypical...

Granulomatosis with polyangiitis (GPA, previously known as Wegener's granulomatosis) is an autoimmune systemic small-vessel vasculitis, associated with the presence of anti-neurophil cytoplasmic antibodies with a cytoplasmic staining pattern (c-ANCA). It is characterized by necrotizing granulomas, usually affecting the airways and kidneys. GPA should be considered when patients do not improve despite adequate treatment of otologic symptoms, when patients have unspecific symptoms suggesting systemic disease (e...

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)...

Henoch-Schönlein purpura (HSP) is an IgA-mediated small vessels' vasculitis that affects the skin, intestines and kidneys. Pregnancy has been reported as an exacerbating factor. We present the case of a 24-year-old primigravida with HSP that occurred in the third trimester and lasted up to the end of the successful delivery. She had pruritic maculopapular exanthema on her legs. Biopsy of a cutaneous lesion was performed for histopathologic features and direct immunofluorescence (DIF) for the presence of perivascular IgA deposition...
