Abstract
Imaging plays an increasing role for confirming a suspected diagnosis of giant cell arteritis (GCA) or Takayasu arteritis (TAK). Ultrasound, magnetic resonance imaging (MRI), and computed tomography demonstrate a homogeneous, most commonly concentric, arterial wall thickening. 18F-Fluorodeoxyglucose (FDG) positron emission tomography (PET) displays increased FDG uptake of inflamed artery walls delineating increased metabolism. Ultrasound and MRI are recommended to be the initial imaging modalities in cranial GCA and TAK, respectively. Extracranial disease can be confirmed by all four modalities, particularly by PET in case of inflammation of unknown origin. If the diagnosis remains uncertain, additional investigations including biopsy and/or additional imaging are recommended. Imaging should be performed by a trained specialist using appropriate operational procedures and settings with appropriate equipment. Further research is necessary on the role of imaging for disease monitoring. This review will discuss advantages and disadvantages of imaging modalities in the diagnosis of vasculitis.

Abstract
Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) and cryoglobulinemic vasculitis (CV) rarely coexist. An 83-year-old woman was admitted with rapidly progressive renal failure, gastrointestinal hemorrhage and purpura with myeloperoxidase (MPO)-ANCA positivity and cryoglobulinemia. Despite intensive immunosuppressive treatment, she died of aspergillus pneumonia. Autopsy revealed necrotizing crescentic glomerulitis in the majority of the glomeruli, accompanied by partially membranoproliferative-like glomerular changes. Immunofluorescence staining revealed the presence of neutrophil extracellular trap (NET) formation in the glomeruli and cutaneous arteries. These pathological findings suggested that MPO-AAV and/or CV caused NET formation, leading to lethal systemic vasculitis.

Abstract
Better understanding of the pathogenesis and treatment of primary systemic vasculitides (PSV) has led to the development of many potentially clinically relevant biomarkers. Genome-wide association studies have highlighted that MHC class II polymorphisms may influence the development of particular anti-neutrophil cytoplasmic antibody (ANCA) serotypes, but not the clinical phenotype of ANCA-associated vasculitis (AAV). Although ANCAs are overall poor biomarkers of disease activity, they may be useful for the prediction of flares of renal and/or pulmonary vasculitis. Moreover, patients with proteinase 3 (PR3)-AAV may respond better to rituximab than cyclophosphamide. Newer biomarkers of renal vasculitis in AAV include urinary soluble CD163, and may in the future reduce the requirement for renal biopsy. Better understanding of dysregulated neutrophil activation in AAV has led to the identification of novel biomarkers including circulating microparticles, and neutrophil extracellular traps (NETs), although their clinical utility has not yet been realised. Studies examining endothelial injury and repair responses have additionally revealed indices that may have utility as disease activity and/or prognostic biomarkers. Last, next-generation sequencing technologies are revealing monogenic forms of vasculitis, such as deficiency of adenosine deaminase type 2 (DADA2), and are profoundly influencing the approach to the diagnosis and treatment of vasculitis in the young.

Abstract
BACKGROUND Primary systemic vasculitis is a rare condition in children, which often has a slowly progressive course with diffuse symptoms and is therefore easily overlooked. Early initiation of treatment can prevent severe kidney disease. The aim of this study was to survey the extent of renal involvement in children with systemic vasculitis at Oslo University Hospital, Rikshospitalet. MATERIAL AND METHOD This observational retrospective study was based on a review of medical records, laboratory results and renal biopsies from first admission to last check-up at Oslo University Hospital, Rikshospitalet, for the period 2000–14. RESULTS A total of 66 children (35 boys) under 18 years of age were treated at the hospital for primary systemic vasculitis in the period in question. Objective signs of renal involvement were found in 39 (59 %) at the first consultation and in 42 (64 %) over the course of the disease. Twenty-nine patients (44 %) underwent renal biopsy. Of the 41 patients with proven renal involvement that were still alive at the time of the last check-up, 12 continued to require treatment for renal impairment. Three patients had undergone renal transplantation, 18 were in remission on immunosuppressive or antihypertensive treatment, while 11 patients had achieved medication-free renal remission. INTERPRETATION There is a high prevalence of renal involvement in paediatric patients treated for systemic vasculitis at Oslo University Hospital, Rikshospitalet. At their final check-up, the majority of patients continue to require treatment and follow-up for kidney disease.

Abstract
OBJECTIVES The issue of levamisole-adulterated cocaine is emerging as a rapidly growing public health concern due to an increasing number of reports describing its role in cutaneous vasculitis and agranulocytosis. Of note, levamisole is recognized as a contaminant in 69% of the cocaine used within the United States. METHODS We describe a patient who was a chronic cocaine user and developed systemic vasculitis characterized by polyarthralgia, bullous skin lesions, agranulocytosis, and antineutrophil cytoplasmic antibody-positive rapidly progressive glomerulonephritis. RESULTS The skin biopsy specimen demonstrated leukocytoclastic vasculitis. The renal biopsy specimen revealed pauci-immune necrotizing and crescentic glomerulonephritis and unusual deposits with medium electron density composed of granules, microspherules, and rare single fibrils on electron microscopy. CONCLUSIONS The electron microscopic features of levamisole-adulterated cocaine toxicity are novel findings that are presented for the first time, to our knowledge, in this report.

Abstract
We report a 43-year-old man experienced numbness in the distal portion of both legs, which progressed over following two months. Neurological examination showed hypesthesia and muscle weakness in the distal portion of both legs. No abnormal findings were seen on blood test and whole-body contrast enhanced computed tomography (CT). Histopathological findings of the sural nerve and the peroneus brevis muscle showed decreased myelinated nerve fibers with scattered myelin ovoids, vascular occlusion in the epineurium, and inflammatory cell around the arteriole in the muscle bundle. These findings suggested falling in the category as non-systemic vasculitic neuropathy (NSVN). (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET) revealed the increase of FDG uptake in the rectum. Inflammatory cell infiltration was found around the arteriole with fibrinoid necrosis in the histopathological specimen of the rectal mucosal biopsy. This result represented the diagnosis as systemic vasculitis. The diagnosis of NSVN may depend on the sensitivity of diagnostic procedure, and (18)F-FDG PET CT might be a useful tool to detect small or medium-sized vasculitis.

Abstract
The most recent pediatric vasculitis classifications (EULAR/PRINTO/PRES) have proposed the use of an integration of clinical signs and symptoms, laboratory data, imaging and pathologic data. Pediatric vasculitis represent a peculiar clinical-diagnostic model, compared to the corresponding adult pathology chapter, and in particular, dermatopathologic aspects of these diseases identify more specific issues, made contingent by crucial variables such as duration of vasculitis lesion, site of the biopsy, proper biopsy depth, and possibility to correlate histopathological findings with immunopathological results. Possible additional diagnostic difficulties may arise from the fact that, in children, the same systemic disease, such as lupus erythematosus, may present with different clinical manifestations, with histopathological features of a precise type of vasculitis specific for that type of clinical manifestation. Examples are provided by hypocomplementemic urticarial vasculitis, cryoglobulinemic purpura, lymphocytic vasculitis of livedoid lesions. This paper describes the cutaneous histopathological findings of some vasculitis related pediatric diseases, be they pertaining to a systemic vasculitis with corresponding cutaneous vasculitis, to a systemic vasculitis with sporadic cutaneous vasculitic involvement, and to a systemic vasculitis without cutaneous vasculitic involvement. Type and level of histopathological vasculitic involvement, caliber of the vessel, type of vasculitis associated infiltrate, are likewise reliable integration in the complex diagnostic path of vasculitis in childhood. On the basis of these criteria dermatopathologists should be confident in identifying the type of the vasculitis and relate them to a specific pediatric disease.

Abstract
BACKGROUND Systemic small blood vessel vasculitis (SSV) is uncommon among pediatric patients, and the predictive value of the new histopathological classification for SSV in terms of renal outcomes in these patients is unknown. METHODS The study cohort comprised 38 pediatric patients and 285 adult patients with SSV who were treated in a medical center between 1993 and 2012. RESULTS Children accounted for 11.8 % of all patients with SSV diagnosed during the study period. In contrast to the adult patients, the pediatric patients were predominantly female (73.7 vs. 51.9 %; P < 0.05). The prevalence of skin purpura was higher and pulmonary symptoms were less common among pediatric patients than among adult ones (36.8 vs. 13.7 %, P < 0.01 and 26.3 vs. 46.0 %, P < 0.05, respectively). Subtype was correlated with the baseline levels of serum creatinine and treatment response among patients with SSV and was found to have a tendency to predict end-stage renal disease (ESRD) among pediatric patients (hazard ratio 2.273, P < 0.01). The probability of progressing to ESRD was highest in pediatric patients with the sclerotic glomerulonephritis subtype, followed by the mixed, crescentic and focal glomerulonephritis subtypes (in descending order of probability) (P < 0.01). CONCLUSIONS Estimated histopathological classification has a prognostic value for renal outcome and response to therapy in children with SSV.

Abstract
Systemic vasculitis (SV) involving abdominal structures usually has a poor prognosis. Gallbladder vasculitis (GV) has been reported as part of SV (GB-SV) and focal single-organ vasculitis (GB-SOV). We analyzed clinical and histologic characteristics of patients with GV to identify features that differentiate GB-SOV from the systemic forms of GV. To identify affected patients with GV we used pathology databases from our institution and an English-language PubMed search. Clinical manifestations, laboratory and histologic features, treatment administered, and outcomes were recorded. Patients were divided in 2 groups, GB-SOV and GB-SV. As in previous studies of single-organ vasculitis, GB-SOV was only considered to be a sustainable diagnosis if disease beyond the gallbladder was not apparent after a follow-up period of at least 6 months. Sixty-one well-characterized patients with GV were included (6 from our institution). There was no significant sex bias (32 female patients, 29 male). Median age was 52 years (range, 18-94 yr). GB-SOV was found in 20 (33%) and GB-SV in 41 (67%) patients. No differences were observed in age, sex frequency, or duration of gallbladder symptoms between groups. Past episodes of recurrent right-upper quadrant or abdominal pain and lithiasic cholecystitis were more frequent in GB-SOV patients, whereas acalculous cholecystitis occurred more often in GB-SV. In GB-SV, gallbladder-related symptoms occurred more often concomitantly with or after the systemic features, but they sometimes appeared before SV was fully developed (13.5%). Constitutional and musculoskeletal symptoms were reported only in GB-SV patients. Compared to GB-SOV, GB-SV patients presented more often with fever (62.5% vs 20%; p = 0.003) and exhibited higher erythrocyte sedimentation rate levels (80 ± 28 vs 37 ± 25 mm/h, respectively; p = 0.006). All GB-SV patients required glucocorticoids and 50% of them also received cytotoxic agents. Mortality in GB-SV was higher than in GB-SOV (35.5% vs 10%; p = 0.05). Nongranulomatous inflammation with fibrinoid necrosis of medium-sized vessels occurred equally in both groups (>90%). Forms of SV affecting the gallbladder included polyarteritis nodosa (n = 10), hepatitis B virus-associated vasculitis (n = 8), cryoglobulinemic (essential or hepatitis C virus-associated) vasculitis (n = 6), vasculitis associated with autoimmune diseases (n = 6), microscopic polyangiitis (n = 4), eosinophilic granulomatosis with polyangiitis (Churg-Strauss) (n = 4), IgA vasculitis (Henoch-Schönlein) (n = 2), and giant cell arteritis (n = 1).GV is uncommon. Its histology most often consists of a nongranulomatous necrotizing vasculitis affecting medium-sized vessels. GB-SOV is usually discovered after routine cholecystectomy performed because of the presence of local symptoms, gallstone-associated cholecystitis, and contrary to GB-SV, GB-SOV is usually not associated with systemic symptoms. Acute phase reactants and surrogate markers of autoimmunity are usually normal or negative in GB-SOV. GB-SOV does not require systemic antiinflammatory or immunosuppressive therapy; surgery is adequate to achieve cure. GB-SV always warrants immunosuppressant therapy and is associated with high mortality. The finding of GV may precede the generalized manifestations of SV. Therefore, once GV is discovered, studies to determine disease extent and a vigilant follow-up are mandatory.

Abstract
BACKGROUND AND PURPOSE Gender differences in inflammation are well described, with females often showing more robust, oestrogen-associated responses. Here, we investigated the influence of gender, oestrogen and the anti-inflammatory protein annexin A1 (AnxA1) on lipopolysaccharide (LPS)-induced leukocyte-endothelial cell interactions in murine cerebral and mesenteric microvascular beds. EXPERIMENTAL APPROACH Intravital microscopy was used to visualize and quantify the effects of LPS (10 μg·per mouse i.p.) on leukocyte-endothelial interactions in male and female wild-type (WT) mice. The effects of ovariectomy ± oestrogen replacement were examined in WT and AnxA1-null (AnxA1(-/-) ) female mice. KEY RESULTS LPS increased leukocyte adherence in the cerebral and mesenteric beds of both male and female WT mice; females showed exacerbated responses in the brain versus males, but not the mesentery. Ovariectomy further enhanced LPS-induced adhesion in the brain but not the mesentery; its effects were reversed by oestrogen treatment. OVX AnxA1(-/-) mice also showed exaggerated adhesive responses to LPS in the brain. However, these were unresponsive to ovariectomy and, paradoxically, responded to oestrogen with a pronounced increase in basal and LPS-induced leukocyte adhesion in the cerebrovasculature. CONCLUSIONS AND IMPLICATIONS Our data confirm the fundamental role of AnxA1 in limiting the inflammatory response in the central and peripheral microvasculature. They also (i) show that oestrogen acts via an AnxA1-dependent mechanism to protect the cerebral, but not the mesenteric, vasculature from the damaging effects of LPS and (ii) reveal a paradoxical and potentially toxic effect of the steroid in potentiating the central response to LPS in the absence of AnxA1.

AIM To present systemic vasculitis (SV) diagnostic stages. SUBJECTS AND METHODS Immunological and hemostatic parameters were determined, vascular scanning, histological and immunomorphological studies were performed in 360 patients. RESULTS The main diagnostic searching stages were presented, which could reveal the key clinical signs of vasculitis and systemacy of the process, differentiate primary and secondary vasculitides, conduct clinical and instrumental studies, detect specific markers of vascular wall injury, perform a morphological study of biopsy specimens, identify the major pathogenic components of vascular bed lesion, define the possible etiology and form of vasculitis, and make a nosological diagnosis. CONCLUSION The proposed diagnostic steps will be able to specify the nosological form of SV and the activity of the process and to define approaches to pathogenetic therapy.

Abstract
Owing to the suggested role of osteopontin (OPN) in inflammation, autoimmunity and fibrosis, we investigated their serum concentrations in chronic hepatitis C virus (HCV) infected patients with and without autoimmune manifestations and correlated those levels to clinical manifestations and the histological severity of hepatic fibrosis. A total of 70 chronic HCV-infected patients (35 with and 35 without autoimmune rheumatic manifestations) were compared with 35 healthy volunteers matched for age and gender. Epidemiological, clinical, immunochemical and virological data were prospectively collected. OPN serum levels were assessed by an Enzyme Linked Immunosorbant Assay. The mean serum OPN levels were higher in HCV patients with autoimmune rheumatologic manifestations and in patients without; than that for the normal controls (p = 0.000). The mean OPN values progressively increased by increasing severity of liver fibrosis (p = 0.009). Multivariate analysis revealed that the presence of rheumatologic manifestations had the highest predictive value (b = 7.141, Beta = 0.414, p = 0.000) followed by liver fibrosis (b = 4.522, Beta = 0.444, p = 0.000) on the variation of OPN levels in our HCV patients. Among the group of patients with HCV and rheumatologic involvement, OPN serum levels were higher in patients with positive cryoglobulin and rheumatoid factor than in those without, and with systemic vasculitis than in those without. Correlation analysis didn't reveal any statistical significance of OPN with age, serum albumin, aminotransferases and viral load. Our data suggests OPN as a promising marker for HCV associated autoimmune rheumatologic involvement, particularly with regard to development of vasculitis and cryoglobinemia. In addition, it could serve as a biomarker to evaluate the severity of liver damages in HCV infected subjects.

Abstract
My approach to vasculitis and vasculopathy includes: (1) Determine the level of care the patient needs. If I am not sure, I will order a basic laboratory evaluation while I decide on the more specific laboratory tests to order and of course do a skin biopsy. (2) Determine if the eruption represents vasculitis or vasculopathy. The presence of livedo reticularis or retiform purpura points toward vasculopathy, but keep in mind the overlap, especially with the ANCA-associated vasculitides. (3) If vasculitis, rule out the secondary causes (ie, infection, drug reactions, malignancy, connective-tissue disorders) first. (4) Determine the size of the vessel involvement and the organ systems involved, which will narrow down the differential diagnosis. Although no one approach works for everyone, I find this method to be simple and keeps you organized when tackling the workup of vasculitis and vasculopathy.

Abstract
AIM To evaluate the efficacy of new therapeutic modalities with the observation period of three years on patients with isolated ocular vasculitis in comparison with ocular vasculitis as a systemic disease. METHODS The effectiveness of the therapy was assessed based on the changes in visual acuity and degree of ocular inflammation (mild, medium, moderate, severe) with the following parameters: vitreous body cloudiness, blood vessels layering, macula oedema, blood vessels occlusion and new vascularisation RESULTS New therapeutic modalities resulted in reduction in the number of patients with severe inflammation in the group of isolated ocular vasculitis from 8(13.5%) to 7(12.2%) after three years, while the number of patients with mild inflammation increased from 13(20.7%) to 18 (29.3%) in the same group (p>0.05). The number of patients with severe ocular inflammation in a group of ocular vasculitis as systemic disease increased from 3(16.2%) to 4(21.6%), because of the presence of patients with Behçet's disease. The number of patients with visual acuity less than 0.1 decreased from 11(17%) to 8(13.4%) in a group of patients with ocular vasculitis as systemic disease, which was associated with the presence of Behçet's disease too (p>0.05). CONCLUSIONS Although the effect of new therapeutic modalities did not result in statistically significant improvement in visual acuity and reducing inflammation, systemic and intravitreal corticosteroids with steroid-sparing immunomodulatory therapy represents effective strategies in forms of isolated ocular vasculitis and ocular vasculitis as systemic disease.

Abstract
We present a case of a patient with systemic vasculitis suffering--besides heart, skin and gastrointestinal lesions--from the rarely reported involvement of the central nervous system. Even though the diagnosis could not be ascertained precisely, immunosuppressive therapy led to prompt regression of symptoms including initially present neurologic manifestations.

Abstract
The systemic vasculitides are characterized by inflammation of blood vessel walls. Vessels of any type, in any organ can be affected, resulting in a broad spectrum of signs and symptoms. The heterogenous nature of vasculitides presents a diagnostic challenge. The American College of Rheumatology classification criteria and the Chapel Hill Consensus Conference nomenclature are the most widely used to distinguish different forms of vasculitis. The Chapel Hill Consensus Conference nomenclature defines 10 primary vasculitides based on vessel size (large, medium, and small). The diagnosis relies on the recognition of a compatible clinical presentation supported by specific laboratory or imaging tests and confirmatory histology. Antineutrophilic cytoplasmic antibody testing has been of particular benefit in defining a subgroup of small vessel vasculitides. Treatment is based on clinical presentation and the pattern of organ involvement. Glucocorticoids are the primary treatment for many forms of vasculitis. Additional immunosuppressive agents, including methotrexate and cyclophosphamide, are sometimes required. Newer approaches, such as the use of anti-tumor necrosis factor or B cell therapies, are being tried in resistant cases. Patients can experience considerable treatment-related toxicity, especially infection from immunosuppressive therapy and adverse effects from steroids (e.g., osteoporosis, diabetes mellitus, cataract). Vitamin D and calcium prophylaxis are recommended in patients on long-term steroid therapy.

Abstract
The systemic vasculitides are a complex and often serious group of disorders which, while uncommon, require careful management in order to ensure optimal outcome. In most cases there is no known cause. Multi-system disease is likely to be fatal without judicious use of immunosuppression. A prompt diagnosis is necessary to preserve organ function. Comprehensive and repeated disease assessment is a necessary basis for planning therapy and modification of treatment protocols according to response. Therapies typically include glucocorticoids and, especially for small and medium vessel vasculitis, an effective immunosuppressive agent. Cyclophosphamide is currently the standard therapy for small vessel multi-system vasculitis, but other agents are now being evaluated in large randomized trials. Comorbidity is common in patients with vasculitis, including the cumulative effects of potentially toxic therapy. Long-term evaluation of patients is important in order to detect and manage relapses.
