    Purpose: Angioplasty effectively relieves coronary artery stenosis but is often followed by restenosis. Endovascular radiation (β or γ) at the time of angioplasty prevents restenosis in a large proportion of vessels in swine (short term) and humans (short and long term). Little information is available about the effects of this radiation exposure beyond the wall of the coronary arteries. Methods and Materials: Samples were obtained from 76 minipigs in the course of several experiments designed to evaluate endovascular brachytherapy: 76 of 114 coronary arteries and 6 of 12 iliac arteries were exposed to endovascular radiation from 32 P sources (35 Gy at 0.5 mm from the intima). Two-thirds of the vessels had angioplasty or stenting. The vessels were systematically examined either at 28 days or at 6 months after radiation. Results: We found an unexpected lesion: acute necrotizing vasculitis in arterioles located ≤2.05 mm from the target artery. It was characterized by fibrinoid necrosis of the wall, often associated with lymphocytic exudates or thrombosis. Based on the review of perpendicular sections of tissue samples, the arterioles had received between 6 and 40 Gy. This arteriolar vasculitis occurred at 28 days in samples from 51% of irradiated coronary arteries and 100% of irradiated iliac arteries. By 6 months, the incidence of acute vasculitis decreased to 24% around the coronary arteries. However, at that time, healing vasculitis was evident, often with luminal narrowing, in 46% of samples. Vasculitis was not seen in any of 44 samples from unirradiated vessels (0%) and had no relation to angioplasty, stenting, or their sequelae. This radiation-associated vasculitis in the swine resembles the localized lymphocytic vasculitis that we have reported in tissues of humans exposed to external radiation. On the other hand, it is quite different from the various types of systemic vasculitis that occur in nonirradiated humans. Conclusion: Endoarterial brachytherapy

    Gastrointestinal system can be involved in primary and secondary vasculitides. The recent data regarding the pathophysiology, clinical findings, diagnosis, management, and outcome of gastrointestinal involvement in different types of vasculitis are reviewed. Diagnosis of gastrointestinal vasculitis may be difficult and relies mostly on imaging, because biopsy samples are hard to obtain and superficial mucosal biopsies have a low yield. There are conflicting reports on the association of antineutrophilic cytoplasmic antibodies (ANCA) type with the frequency of gastrointestinal involvement in ANCA-associated vasculitis. Pancreatitis is a rare but serious complication of ANCA-associated vasculitis. Terminal ileitis may be observed in immunoglobulin A vasculitis and can be hard to distinguish from Crohn's disease. High fecal calprotectin levels can indicate active gastrointestinal involvement in both immunoglobulin A vasculitis and Behçet's syndrome. Refractory gastrointestinal involvement in Behçet's syndrome can be treated with thalidomide and/or TNF-α antagonists. The outcome of mesenteric vasculitis in systemic lupus erythematosus can be improved with high-dose glucocorticoids and cyclophosphamide or rituximab. Gastrointestinal system can be commonly involved in immunoglobulin A vasculitis, ANCA-associated vasculitis, polyarteritis nodosa, and Behçet's syndrome and can be an important cause of morbidity and mortality. Treatment depends on the type of vasculitis and is usually with high-dose corticosteroids and immunosuppressives.

    Acute multifocal posterior placoid pigment epitheliopathy (APMPPE) is an unusual self-limited retinal disorder that has been associated with various systemic complications. To our knowledge, three prior cases associated with cerebral vasculitis have been described. This article describes a patient with APMPPE and angiographically documented cerebral vasculitis who was notable because of (a) the presence of two different cerebral ischemic events, occurring 1 month apart, and (b) the long latency (3 months) between the onset of ocular symptoms and the second cerebral ischemic event. Recognition of the association between APMPPE and cerebral vasculitis may permit early treatment of CNS involvement and prevention of morbidity.

    The purpose of this review is to provide a critical analysis of the recent literature on this topic, with particular focus on the most relevant studies published over the last year. Many studies are published every year on the diagnosis, pathogenesis and treatment of pulmonary involvement in antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV). The main subjects covered by this article are the pathogenesis, diagnosis and clinical aspects of lung involvement in ANCA-associated vasculitis and non-ANCA-associated vasculitis. Lung involvement is a common feature in systemic vasculitis. The lungs are one of the most frequently involved organs in systemic vasculitis. In order to provide an update on the recent advances in the pathogenesis, clinical features and novel treatments of lung involvement in systemic vasculitis, a systematic MedLine search has been performed.Most of the data analyzed have confirmed that lung involvement seems to develop more frequently in patients with myeloperoxidase-ANCA-positive AAV, mainly in those with a diagnosis of microscopic polyangiitis (MPA), compared with patients with proteinase 3 ANCA-positive AAV. Moreover, among non-ANCA-associated vasculitis lung involvement may represent a worrying complication of the disease, mainly when associated with vascular involvement.

    Full Text Available Objective. To estimate the incidence rate of clinically apparent arterial thrombotic events and associated comorbidities in patients with primary systemic vasculitis. Methods. Using large cohort administrative data from Quebec, Canada, we identified patients with vasculitis, including polyarteritis nodosa (PAN and granulomatosis with polyangiitis (GPA. Incident acute myocardial infarctions (AMIs and cerebrovascular accidents (CVAs after the diagnosis of vasculitis were ascertained in the PAN and GPA group via billing and hospitalization data. These were compared to rates of a general population comparator group. The incidences of comorbidities (type 2 diabetes mellitus, dyslipidemia, and hypertension were also collected. Results. Among the 626 patients identified with vasculitis, 19.7% had PAN, 2.9% had Kawasaki disease, 23.8% had GPA, 52.4% had GCA, and 1.3% had Takayasu arteritis. The AMI rate was substantially higher in males aged 18–44 with PAN, with rates up to 268.1 events per 10,000 patient years [95% CI 67.1–1070.2], approximately 30 times that in the age- and sex-matched control group. The CVA rate was also substantially higher, particularly in adults aged 45–65. Patients with vasculitis had elevated incidences of diabetes, dyslipidemia, and hypertension versus the general population. Conclusion. Atherothrombotic rates were elevated in patients identified as having primary systemic vasculitis. While incident rates of cardiovascular comorbidities were also increased, the substantial elevation in AMIs seen in young adults suggests a disease-specific component which requires further investigation.

    Renal failure secondary to ANCA-associated vasculitis represents a clinical and therapeutic challenge. In this study, we aimed to assess the treatment response rates and long-term outcomes of vasculitis patients presenting with renal failure. This retrospective study included 151 patients with renal vasculitis from three hospitals who underwent a renal biopsy between 1997 and 2014. Patients with renal failure which required dialysis at the onset were compared to those presenting with more preserved renal function. The primary end point was treatment response and patient surivival. Patients with severe renal involvement had a lower response to treatment compared to those having preserved renal function (26.6 versus 93.4%; p renal recovery (41.6 versus 12.5%; p = 0.05). A higher incidence of severe infections was observed among patients with severe renal involvement (38.4 versus 18.1%, p = 0.01). The mortality rate was significantly higher among vasculitis patients presenting with renal failure (53.8 versus 22.2%, p = 0.001). Global survival at 1 and 5 years was 60 and 47% in patients requiring dialysis compared with 90 and 80% among those with more preserved renal function (p renal dysfunction represents an independent risk factor for patient survival in renal vasculitis. Patients requiring dialysis associate a lower response rate to immunosuppressive therapy and a higher incidence of severe infections.

    Atherosclerotic peripheral vascular disease is a common presenting cause for digital ischaemia in life long smokers. Acute severe Type II Cryoglobulinaemic vasculitis is a rare yet important cause, which may present with similar clinical features and which if undiagnosed may be rapidly fatal. Following the instigation of therapy with intravenous methylprednisolone and cyclophosphamide this patient made an excellent recovery.

    Abstract Although the presence of antineutrophil cytoplasmic antibodies (ANCA) has been reported in patients with systemic sclerosis (SSc), the association of SSc and systemic vasculitis has rarely been described. We obtained information on cases of systemic vasculitis associated with SSc in France from the French Vasculitis Study Group and all members of the French Research Group on Systemic Sclerosis. We identified 12 patients with systemic vasculitis associated with SSc: 9 with ANCA-associated systemic vasculitis (AASV) and 3 with mixed cryoglobulinemia vasculitis (MCV). In all AASV patients, SSc was of the limited type. The main complication of SSc was pulmonary fibrosis. Only 2 patients underwent a D-penicillamine regimen before the occurrence of AASV. The characteristics of AASV were microscopic polyangiitis (n = 7) and renal limited vasculitis (n = 2). Anti-myeloperoxidase antibodies were found in 8 of the 9 patients. The Five Factor Score was above 1 in 3 of the 9 patients. Of the 3 patients with MCV, Sjögren syndrome was confirmed in 2. We compared our findings with the results of a literature review (42 previously reported cases of AASV with SSc). Although rare, vasculitis is a complication of SSc. AASV is the most frequent type, and its diagnosis can be challenging when the kidney is injured. Better awareness of this rare association could facilitate earlier diagnosis and appropriate management to reduce damage. PMID:23263715

    IgA vasculitis is a systemic small vessel leukocytoclastic vasculitis characterized by skin purpura, arthritis, abdominal pain and nephritis. Most of the abdominal complications are due to edema and hemorrhage in the small bowel wall, but rarely to acute secondary pancreatitis. Here, we report a 53-year-old woman who presented with acute pancreatitis and, secondarily, developed skin purpura and arthritis at the seventh day of the clinical onset. Biological tests and computed tomographic scan allowed to rule out another cause of pancreatitis and IgA vasculitis was diagnosed as its etiology. The outcome was favorable without any relapse on glucocorticoids. Despite its rarity, pancreatitis is a potential life-threatening complication of IgA vasculitis in which the role of glucocorticoids and immunosuppressive drugs remains uncertain. A prompt elimination of other usual pancreatitis etiologies is mandatory to improve the management of the patients. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI).

    Full Text Available The systemic vasculitides are multifocal diseases characterized by the presence of blood vessel inflammation in multiple organ systems. Their clinical presentation is variable extending from self-limited illness to critical complications including diffuse alveolar hemorrhage and glomerulonephritis. Alveolar hemorrhage is a lifethreatening manifestation of pulmonary vasculitis that can rapidly progress into acute respiratory failure requiring ventilatory support. We present the case of a 74-year-old patient admitted to the Intensive Care Unit with severe hypoxic respiratory failure and diffuse alveolar infiltrates in chest imaging that was later diagnosed as antineutrophil cytoplasmic antibodies-associated vasculitis. The report highlights the importance of differentiate between alveolar hemorrhage and acute respiratory distress syndrome of other etiology because alveolar hemorrhage is reversible with prompt initiation of treatment.

    The term ''systemic vasculitis'' encompasses a diverse set of diseases linked by the presence of blood-vessel inflammation that are often associated with critical complications. These diseases are uncommon in childhood and are frequently subjected to a delayed diagnosis. Although the diagnosis and treatment may be similar for adult and childhood systemic vasculitides, the prevalence and classification vary according to the age group under investigation. For example, Kawasaki disease affects children while it is rarely encountered in adults. In 2006, the European League Against Rheumatism (EULAR) and the Pediatric Rheumatology European Society (PReS) proposed a classification system for childhood vasculitis adopting the system devised in the Chapel Hill Consensus Conference in 1993, which categorizes vasculitides according to the predominant size of the involved blood vessels into small, medium and large vessel diseases. Currently, medical imaging has a pivotal role in the diagnosis of vasculitis given recent developments in the imaging of blood vessels. For example, early diagnosis of coronary artery aneurysms, a serious complication of Kawasaki disease, is now possible by magnetic resonance imaging (MRI) of the heart and multidetector computed tomography (MDCT); positron emission tomography/CT (PET/CT) helps to assess active vascular inflammation in Takayasu arteritis. Our review offers a unique approach using the integration of the proposed classification criteria for common systemic childhood vasculitides with their most frequent imaging findings, along with differential diagnoses and an algorithm for diagnosis based on common findings. It should help radiologists and clinicians reach an early diagnosis, therefore facilitating the ultimate goal of proper management of affected children. (orig.)

    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.

    Full Text Available The clinical presentation of Systemic Lupus Erythematosus (SLE is diverse and vasculitis can be a potential manifestation. Cutaneous lesions involving small vessels are the most frequent presentation. However, medium and large vessel vasculitis may present with life-threatening visceral manifestations. We present a unique case of pelvic vasculitis mimicking a pelvic mass as an initial presentation of SLE. There are case reports of systemic vasculitis involving the female genital tract with giant cell arteritis (GCA, polyarteritis nodosa (PAN, and granulomatous with polyangiitis and microscopic polyangiitis (GPA/MPA, among others, but only a few cases attributed to SLE. Awareness of this condition and a prompt diagnosis are warranted as this is a severe and potentially life-threatening condition.

    Objective To compare illness perceptions among patients with different forms of vasculitis, identify risk factors for negative illness perceptions, and determine the association between illness perceptions and fatigue. Methods Participants were recruited from an online registry in vasculitis to complete the revised Illness Perception Questionnaire (IPQ-R). Mean scores on each IPQ-R dimension were compared across types of vasculitis. Cluster analysis and stepwise regression identified predictors of negative illness perception. Fatigue was measured using the general subscale of the Multidimensional Fatigue Inventory (MFI). Patient-reported measures of disease activity and IPQ-R dimensions were assessed in relation to MFI scores using linear regression in sequential, additive models with model-fit comparisons. Results 692 participants with 9 forms of vasculitis completed the IPQ-R. For 6 out of 8 IPQ-R dimensions, there were no significant differences in mean scores between the different vasculitides. Scores in identity and cyclical dimensions were significantly higher in Behçet’s disease compared to other types of vasculitis (13.5 vs 10.7; 4.0 vs 3.2, pvasculitis, and younger age is a risk factor for negative illness perceptions. Illness perceptions explain differences in fatigue scores beyond what can be explained by measures of disease activity. PMID:23861259

    Full Text Available Evidence is lacking for direct pathogenicity of human anti-proteinase-3 (PR3 antibodies in development of systemic vasculitis and granulomatosis with polyangiitis (GPA, Wegener's granulomatosis. Progress in study of these antibodies in rodents has been hampered by lack of PR3 expression on murine neutrophils, and by different Fc-receptor affinities for IgG across species. Therefore, we tested whether human anti-PR3 antibodies can induce acute vasculitis in mice with a human immune system. Chimeric mice were generated by injecting human haematopoietic stem cells into irradiated NOD-scid-IL2Rγ⁻/⁻ mice. Matched chimera mice were treated with human IgG from patients with: anti-PR3 positive renal and lung vasculitis; patients with non-vasculitic renal disease; or healthy controls. Six-days later, 39% of anti-PR3 treated mice had haematuria, compared with none of controls. There was punctate bleeding on the surface of lungs of anti-PR3 treated animals, with histological evidence of vasculitis and haemorrhage. Anti-PR3 treated mice had mild pauci-immune proliferative glomerulonephritis, with infiltration of human and mouse leukocytes. In 3 mice (17% more severe glomerular injury was present. There were no glomerular changes in controls. Human IgG from patients with anti-PR3 autoantibodies is therefore pathogenic. This model of anti-PR3 antibody-mediated vasculitis may be useful in dissecting mechanisms of microvascular injury.

There was punctate bleeding on the surface of lungs of anti-PR3 treated animals, with histological evidence of vasculitis and haemorrhage. Anti-PR3 treated mice had mild pauci-immune proliferative glomerulonephritis, with infiltration of human and mouse leukocytes. In 3 mice (17%) more severe glomerular injury was present. There were no glomerular changes in controls. Human IgG from patients with anti-PR3 autoantibodies is therefore pathogenic. This model of anti-PR3 antibody-mediated vasculitis may be useful in dissecting mechanisms of microvascular injury.

    Vasculitis has been described in most types of inflammatory arthritis. The best described and most widely recognised form is rheumatoid vasculitis. The incidence of systemic rheumatoid vasculitis has declined significantly following the general early use of methotrexate in the 1990s, and it is now a rare form of vasculitis. Treatment of rheumatoid vasculitis is conventionally with glucocorticoids and cyclophosphamide, but there is an increasing role for rituximab similar to that in other types of vasculitis. Despite these developments the mortality of rheumatoid vasculitis remains high. Vasculitis in other types of inflammatory arthritis is less well described and the treatment remains empirical.

    The central nervous system (CNS) may be involved by a variety of inflammatory diseases of blood vessels. These include primary angiitis of the central nervous system (PACNS), a rare disorder specifically targeting the CNS vasculature, and the systemic vasculitides which may affect the CNS among other organs and systems. Both situations are severe and convey a guarded prognosis. PACNS usually presents with headache and cognitive impairment. Focal symptoms are infrequent at disease onset but are common in more advanced stages. The diagnosis of PACNS is difficult because, although magnetic resonance imaging is almost invariably abnormal, findings are non specific. Angiography has limited sensitivity and specificity. Brain and leptomeningeal biopsy may provide a definitive diagnosis when disclosing blood vessel inflammation and are also useful to exclude other conditions presenting with similar findings. However, since lesions are segmental, a normal biopsy does not completely exclude PACNS. Secondary CNS involvement by systemic vasculitis occurs in less than one fifth of patients but may be devastating. A prompt recognition and aggressive treatment is crucial to avoid permanent damage and dysfunction. Glucocorticoids and cyclophosphamide are recommended for patients with PACNS and for patients with secondary CNS involvement by small-medium-sized systemic vasculitis. CNS involvement in large-vessel vasculitis is usually managed with high-dose glucocorticoids (giant-cell arteritis) or glucocorticoids and immunosuppressive agents (Takayasu’s disease). However, in large vessel vasculitis, where CNS symptoms are usually due to involvement of extracranial arteries (Takayasu’s disease) or proximal portions of intracranial arteries (giant-cell arteritis), revascularization procedures may also have an important role.

    Purpose of review Ophthalmologists and rheumatologists frequently miscommunicate in consulting on patients with retinal vasculitis. This report seeks to establish a common understanding of the term, retinal vasculitis, and to review recent papers on this diagnosis. Recent findings 1) The genetic basis of some rare forms of retinal vascular disease have recently been described. Identified genes include CAPN5, TREX1, and TNFAIP3; 2) Behçet’s disease is a systemic illness that is very commonly associated with occlusive retinal vasculitis; 3) retinal imaging including fluorescein angiography and other newer imaging modalities has proven crucial to the identification and characterization of retinal vasculitis and its complications; 4) although monoclonal antibodies to IL-17A or IL-1 beta failed in trials for Behçet’s disease, antibodies to TNF alpha, either infliximab or adalimumab, have demonstrated consistent benefit in managing this disease. Interferon treatment and B cell depletion therapy via rituximab may be beneficial in certain types of retinal vasculitis. Summary Retinal vasculitis is an important entity for rheumatologists to understand. Retinal vasculitis associated with Behçet’s disease responds to monoclonal antibodies that neutralize TNF, but the many other forms of non-infectious retinal vasculitis may require alternate therapeutic management.

    The aim of this review is to define childhood vasculitis and to highlight new causative factors and treatment modalities under the guidance of recently published studies. Childhood vasculitis is difficult to diagnose because of the wide variation in the symptoms and signs. New nomenclature and classification criteria were proposed for the diagnosis of pediatric vasculitis. Recently, progress has been made toward understanding the genetic susceptibility to pediatric vasculitis as it was in other diseases. Various radiological techniques provide great opportunities in establishing the diagnosis of pediatric vasculitis. Mild central nervous system disease can accompany Henoch-Schonlein purpura and can go unnoticed. Antineutrophilic cytoplasmic antibody-associated vasculitis is rare in children. Increased severity of the disease, subglottic stenosis, and renal disease are described more frequently among children. Biological therapies are used with success in children as in adults. Future studies, whose aims are to evaluate treatment responses, prognosis and to design guidelines for activity, and damage index of vasculitis for children are required. Henoch-Schonlein purpura and Kawasaki disease are the most frequent vasculitides of children. Experience from adult studies for treatment and prognosis are usually used because of low incidence of other vasculitides in children. Multicenter studies of pediatric vasculitis should be conducted to detail treatment responses and prognosis in children.

    Cutaneous vasculities (CV) represents a diagnostic challenge, occurs as primary cutaneous disorder or as a manifestation of other entities. To search the cause of CV. Methods: Patients with CV were prospectively evaluated. In all patients, skin biopsies were drawn, and direct immunofluorescence was done in most of the patients. American College of Rheumatology (ACR) and Chapel Hill Consensus Conference Criteria (CHCC) were used for classification. 32 patients were studied. There was female predominance (71.8%). Children presented drug-associated CV or Schönlein-Henoch púrpura (SHP). Adults presented more frequently SHP, systemic lupus erythematosus or paraneoplastic vasculitis, other diagnosis as polyarteritis nodosa, microscopic polyangiitis, thrombotic vasculitis (post-puerperal), antiphospholipid syndrome, Churg-Strauss syndrome, and drug-associated CV were presented. Using the ACR and CHCC criteria, 50% of cases were classified. In our institution, during this work the etiologic diagnostic of CV increased more than twice. However, in the case of HSV or LA and SHP none of the proposed criteria had high specificity; other parameters were used to discern between both. Six patients remained as not classified. In our view, cryoglobulins and hepatitis serology do not seem useful unless patient’s history supports they need to be done. Unclassified patients were followed-up closely for 2 years.

    Full Text Available A 55-year-old female presented with bilateral progressive retinal vasculitis. She was on systemic and intravitreal steroids on the basis of uveitis work-up result (negative result including rapid plasma reagin, but her visual acuity continued to deteriorate to light perception only. Ocular examination showed retinal vasculitis, multiple yellow placoid lesions and severe macula edema in both eyes. Repeated work-up revealed positivity of fluorescent treponemal antibody-absorption in serum and subsequently in cerebrospinal fluid. Ocular syphilis was diagnosed. And intravenous penicillin G resulted in rapid resolution of vasculitis and macular edema. To avoid delay in the diagnosis of ocular syphilis, high index of suspicion and repeating serological tests (including both treponemal and non-treponemal tests are warranted.

    Retinal vasculitis is a sight-threatening intraocular inflammation affecting the retinal vessels. It may occur as an isolated ocular condition, as a manifestation of infectious or neoplastic disorders, or in association with a systemic inflammatory disease. The search for an underlying etiology should be approached in a multidisciplinary fashion based on a thorough history, review of systems, physical examination, and laboratory evaluation. Discrimination between infectious and noninfectious etiologies of retinal vasculitis is important because their treatment is different. This review is based on recently published articles on retinal vasculitis and deals with its clinical diagnosis, its link with systemic diseases, and its laboratory investigation.

    Among the various renal manifestations of sarcoidosis, granulomatous inflammation confined to the tubulointerstitial compartment is the most commonly reported finding. We present the case of a 66-year-old man with acute kidney injury, hypercalcemia, mild restrictive pulmonary disease, and neurologic signs of parietal lobe dysfunction. Kidney biopsy showed diffuse interstitial inflammation with noncaseating granulomas that exhibited the unusual feature of infiltrating the walls of small arteries with destruction of the elastic lamina, consistent with granulomatous vasculitis. The findings of granulomatous interstitial nephritis on kidney biopsy, hypercalcemia, and possible cerebral and pulmonary involvement in the absence of other infectious, drug-induced, or autoimmune causes of granulomatous disease established the diagnosis of sarcoidosis. Pulse methylprednisolone followed by maintenance prednisone therapy led to improvement in kidney function, hypercalcemia, and neurologic symptoms. Vasculocentric granulomatous interstitial nephritis with granulomatous vasculitis is a rare and under-recognized manifestation of renal sarcoidosis. Copyright © 2012 National Kidney Foundation, Inc.

    Antineutrophil cytoplasmic antibodies (ANCA) are associated with vasculitis, including vasculitis induced by drugs such as the thionamides. The affected organ systems in thionamide-induced vasculitis have been primarily renal, musculoskeletal, and dermatologic. We describe the first case of thionamide-induced central nervous system vasculitis presenting as confusion, with complete resolution after discontinuation of propylthiouracil. We review the literature and summarize 42 additional cases of thionamide-induced ANCA-positive vasculitis since 1992. Propylthiouracil was responsible in 93% of cases and the predominant ANCA pattern on immunofluorescent staining was perinuclear (p-ANCA). Clinical improvement occurred after drug discontinuation in 93%, steroid therapy was used in some cases. The mean duration of treatment with thionamides was 35 months prior to presentation. Long-term medical treatment with thionamides for hyperthyroidism may increase the risk of this severe side effect.

    Full Text Available Purpose. To report favorable outcome of a case of acute posterior multifocal placoid pigment epitheliopathy (APMPPE associated with cerebral vasculitis after treatment with immunosuppressive therapy by mitoxantrone. Design. Single case report. Method. A 22-year-old man presented with acute isolated bilateral loss of vision revealing APMPPE. Corticosteroid therapy was initiated and visual acuity gradually improved. Seventeen days later, visual function deteriorated again, associated with flu-like syndrome and severe headaches. A relapse of APMPPE was diagnosed, complicated with lymphocytic meningitis and cerebral ischemia. Intravenous therapy with mitoxantrone was performed in combination with methylprednisolone. Results. Headaches disappeared in a few days whereas visual acuity gradually improved and stabilized at 20/40 in the right eye and 20/32 in the left eye. No adverse event was observed. Clinical improvement was confirmed by magnetic resonance imaging. Conclusion. Cerebral vasculitis is the most severe complication of the extraocular manifestations of APMPEE. This diagnosis should be evoked when severe headaches or behavior disorder are associated with APMPEE.

    Full Text Available Introduction: Vasculitis is an inflammation systems may be involved of blood vessels due to various origins. Vessels of the peripheral and/or central nervous. Vasculitis of the CNS is rare and occurs in the context of systemic diseases or as primary angiitis of the CNS. Epidemiology: The overall incidence of primary vasculitis is about 40/1,000,000 persons [excluding giant cell (temporal arteritis, GCA]. Its incidence increases with age. The incidence of GCA is much higher (around 200/1,000,000 persons in the age group[50 years. Clinical Presentation: Clinical and pathological presentation in CNS vasculitis represents a wide spectrum. Among others, headache, cranial nerve affections, encephalopathy, seizures, psychosis, myelitis, stroke, intracranial haemorrhage and aseptic meningoencephalitis are described. Primary and secondary vasculitides leading more frequently to CNS manifestations are discussed. Primary and secondary Vasculitides: Including Giant Cell (Temporal Arteritis , Takayasu arteritis, Polyarteritis nodosa, Primary angiitis of the CNS, Wegener’s granulomatosis, and Connective tissue diseases, such as systemic lupus erythematosus (SLE, scleroderma, rheumatoid arthritis, mixed connective disease and Sjögren syndrome, are systemic immune-mediated diseases that lead to multiple organ affections. Cerebral Vasculitis: Imaging and Differential Diagnosis: Vasculitides represent a heterogeneous group of inflammatory diseases that affect blood vessel walls of varying calibers (inflammatory vasculopathy. Since the devastating symptoms of CNS vasculitis are at least partially reversible, early diagnosis and appropriate treatment are important. In order to establish a differential diagnosis clinical features, disease progression, age of onset, blood results, as well as CSF examinations have to be taken into consideration. Neuroimaging techniques, such as MRI and DSA, play a central role in the diagnosis and disease monitoring .The diagnostic

    Objectives Patients vary in their beliefs related to the cause of serious illness. The impact of these beliefs among patients with systemic vasculitis is not known. This study aimed to describe causal attributions about disease-onset and relapse in systemic vasculitis and to examine whether causal beliefs a) differ by type of vasculitis; and b) are associated with negative health outcomes. Methods Patients with vasculitis were recruited to complete an online questionnaire. Categories of causal beliefs were assessed with the Revised Illness Perception Questionnaire (IPQ-R). Differences in beliefs about disease-onset versus relapse were compared across different forms of vasculitis. Causal beliefs were assessed in association with several health outcomes including fatigue, functional impairments, and personal understanding of the condition. Results 692 patients representing 9 forms of vasculitis completed the questionnaire. The majority (90%) of patients had beliefs about the cause of their illness. Causal attributions were highly variable, but altered immunity and stress were the most commonly agreed upon causal beliefs. Frequencies of causal beliefs were strikingly similar across different forms of vasculitis, with few notable exceptions primarily in Behçet’s disease. Beliefs differed about causes of disease-onset versus relapse. Specific beliefs about disease-onset and relapse were weakly associated with fatigue, functional impairments, and understanding of the condition. Conclusion Patient beliefs related to the cause of systemic vasculitis are highly variable. Patterns of causal beliefs are associated with important negative health outcomes. Clinicians who care for patients with vasculitis should be mindful of these associations and consider asking about patients’ causal beliefs. PMID:24634202

    To evaluate TOF 3D magnetic resonance angiography (MRA) of the intracranial arteries in patients with vasculitis or vasculitis-like benign angiopathy of the central nervous system (CNS). Method: The results of MRA in 20 patients with clinically and radiographically proven vasculitis (17/20) or vasculitis-like benign angiopathy (3/20) of the CNS were retrospectively analysed. Patients with hyperintense lesions of more than 3 mm on T 2 -weighted MRI images were included in this trial. An inflammatory, embolic, neurodegenerative or metastatic origin of these lesions was excluded by extensive clinical studies. For the MR-examination a TOF 3D FISP sequence was used on a 1.5 T imager. Results: MRA showed characteristic changes for vasculitis or angiopathy in 15 of 20 patients (75%). Conclusions: In patients suspected of having a vasculitis or vasculitis-like angiopathy, MRA is recommended as a non-invasive modality. If the results of MRI and extensive clinical studies are carefully correlated, MRA may substitute conventional angiography in cases with typical vascular changes. (orig.) [de

    Purpose of review Due to the well-known toxicities of cyclophosphamide, substantial interest exists in finding other therapies to treat primary systemic vasculitis. Biologic agents have been proposed as an alternative to cyclophosphamide for these disorders because of their recent success in treating other rheumatic diseases. This article reviews the current state-of-the-art with regards to the use of biologic agents as a treatment for systemic vasculitis. Recent findings The greatest amount of experience with these agents for the treatment of systemic vasculitis is with anti-tumor necrosis factor agents, pooled intravenous immunoglobulin, and anti-B cell therapies such as rituximab. Intravenous immunoglobulin is already a standard therapy for Kawasaki's disease, but should also be considered for the treatment of ANCA-associated vasculitis when standard therapies are either ineffective or contraindicated. Early experience with tumor necrosis factor inhibitors indicates that they may be effective for the treatment of Takayasu's arteritis, but their role in the treatment of other forms of vasculitis remains controversial. Early experience with rituximab for the treatment of several forms of vasculitis has been quite promising, but must be confirmed by ongoing randomized clinical trials. Summary Biologic agents represent the next evolution in treatment for the primary systemic vasculitides. Greater understanding of these diseases has allowed use to move further away from non-specific, highly toxic therapies towards a more directed approach. As our experience with these agents increases, they will likely form the keystone of treatment in the near future. PMID:19077713

    Full Text Available A twenty year old male presented with purpuric lesions with chronic painful ulcers over the lower extremities and a recurrent pruritic rash on the trunk for 10 years. He was diagnosed as idiopathic leukocytoclastic vasculitis (LCV after investigations failed to reveal a systemic association. He was treated with immunosuppressants at each visit with partial remission. In 2004, he was diagnosed with bronchial asthma and allergic rhinitis. In his recent admission, he showed necrotic ulcers on legs and extensive shiny, truncal micropapules. Examination revealed maxillary sinus tenderness and loss of sensation on the medial aspect of the left lower limb. Biopsy of ulcer and the micropapules showed the presence of extravascular eosinophils, while hematological investigations showed peripheral eosinophilia of 18%, raised serum Immunoglobulin E (IgE, Anti nuclear antibody (ANA positivity and negative antineutrophil cytoplasmic antibody (ANCA. Radiography confirmed maxillary sinusitis, nerve conduction studies revealed mononeuritis of the anterior tibial nerve and pulmonary function tests (PFT were normal. Clinical examination and investigations pointed towards the diagnosis of Churg-Strauss syndrome (CSS. This report highlights the development of full-blown CSS over a period of 12 years in a patient initially diagnosed as idiopathic LCV, emphasizing the need for regular follow-up of resistant and recurrent cases of LCV.

    2015-04-01

    Vasculitis usually presents without a well-known underline cause (idiopathic vasculitis), nevertheless, it is sometimes possible to find out one or more causative agents (secondary vasculitis). Nowadays, thanks to the increasing amount of precise diagnostic tools, a piece of idiopathic vasculitis is reclassified as associated with probable etiology, which can be set off by several factors, such as infections. Infections are considered to be the most common cause of secondary vasculitis. Virtually, every infectious agent can trigger a vasculitis by different mechanisms which can be divided in two main categories: direct and indirect. In the former, infectious agents destroy directly the vascular wall leading, eventually, to a subsequent inflammatory response. In the latter, indirect form, they stimulate an immune response against blood vessels. Different infectious agents are able to directly damage the vascular wall. Among these, it is possible to recognize Staphylococcus spp, Streptococcus spp, Salmonella spp, Treponema spp, Rickettsia spp, Cytomegalovirus, Herpes Simplex Virus 1 and 2, and many others which have a peculiar tropism for endothelial cells. Conversely, another group of microbial agents, such as Mycobacterium tuberculosis, Mycobacterium leprae, Hepatits B Virus, Human Immunodeficiency Virus and others, trigger vasculitis in the indirect way. This is due to the fact that they can share epitopes with the host or modify self-antigens, thus leading to a cross-self reaction of the immune system. These mechanism, in turn, leads to immunological responses classified as type I-IV by Gell-Coombs. Nevertheless, it is difficult to strictly separate the direct and indirect forms, because most infectious agents can cause vasculitis in both ways (mixed forms). This paper will analyze the link between infectious agents and vasculitis, focusing on direct and indirect secondary vasculitis, and on a group of probable infection-related idiopathic vasculitis, and finally

    2002-11-01

    Vasculitis of the nervous system are rare in the elderly. When present, they may constitute an urgent diagnosis and a therapeutic emergency. Clinical expression is rich and without specificity. Atypical signs (unusual course of dementia, systemic signs) or atypical laboratory results (inflammatory syndrome) may suggest the diagnosis of vasculitis. However, as multiple comorbidity is the rule in elderly subjects, searching for intercurrent factors (e.g. atrial fibrilation due to infectious disease causing embolic stroke) may be more contributive than searching for proof of a rare disease (vasculitis) with invasive procedures in this population. Giant cell (temporal) arteritis is the only vasculitis specifically related with age; the vital prognosis of vision may be compromised. Corticosterid therapy must be instituted without delay. Periartritis nodosa begins in 30% of cases after 60 years of age. The clinical features are the same as in younger subjects. Other vasculidis are rare in the elderly. In absence of specific studies in this population, therapeutic protocols are the same as in younger subjects but may have to be adjusted.

    We report a rare case of CNS vasculitis associated with Goodpasture's syndrome in a 34-year-old man, who presented with a seizure and sudden onset of right sided weakness. He also had recurrent hemoptysis of one month's duration. Goodpasture's syndrome is histologically diagnosed by intense linear deposits of IgG along the glomerular basement membrane in both renal and lung tissues. oodpasture's syndrome is a rare disease, characterized by rapidly progressive glomerulonephritis, diffuse pulmonary hemorrhage and circulating antiglomerular basement membrane antibody (anti-GBM antibody). Central nervous system (CNS) manifestations in Goodpasture's syndrome are extremely rare, with only a few cases having been reported in the literature (8 10). Therefore, we present our imaging findings of CNS vasculitis associated with Goodpasture's syndrome, together with a review of the relevant literature. In summary, CNS vasculitis associated with Goodpasture's syndrome is extremely rare. Awareness of the imaging findings, as well as the clinical significance of CNS vasculitis associated with Goodpasture's syndrome, can be helpful in making the correct diagnosis and subsequent management of this rare condition

    Cryoglobulinemic vasculitis (CryoVas) is a small-vessel vasculitis involving mainly the skin, the joints, the peripheral nervous system, and the kidneys. Type I CryoVas is single monoclonal immunoglobulins related to an underlying B-cell lymphoproliferative disorder. Type II and III cryoglobulins, often referred to as mixed cryoglobulinemia, consist of polyclonal immunoglobulin (Ig)G with or without monoclonal IgM with rheumatoid factor activity. Hepatitis C virus (HCV) infection represents the main cause of mixed CryoVas. The 10-year survival rates are 63%, 65%, and 87% in HCV-positive mixed CryoVas, HCV-negative mixed CryoVas, and type I CryoVas patients, respectively. In HCV-positive patients, baseline poor prognostic factors include the presence of severe liver fibrosis, and central nervous system, kidney, and heart involvement. Treatment with antivirals is associated with a good prognosis, whereas use of immunosuppressants (including corticosteroids) is associated with a poor outcome. In HCV-negative patients, pulmonary and gastrointestinal involvement, renal insufficiency, and age > 65 years are independently associated with death. Increased risk of lymphoma also should be underlined. Treatment of type I CryoVas is that of the hemopathy; specific treatment also includes plasma exchange, corticosteroids, rituximab, and ilomedine. In HCV-CryoVas with mild-to-moderate disease, an optimal antiviral treatment should be given. For HCV-CryoVas with severe vasculitis (ie, worsening of renal function, mononeuritis multiplex, extensive skin disease, intestinal ischemia…) control of disease with rituximab, with or without plasmapheresis, is required before initiation of antiviral therapy. Other immunosuppressants should be given only in case of refractory forms of CryoVas, frequently associated with underlying B-cell lymphoma. Copyright © 2015 Elsevier Inc. All rights reserved.

    Dengue fever is a common mosquito-borne viral illness with a clinical spectrum ranging from a simple febrile illness to potentially life-threatening complications such as dengue hemorrhagic fever and dengue shock syndrome. Dengue infection can affect many organs, including the central nervous system. The neurological manifestations reported in dengue infections are meningitis, encephalitis, stroke, acute disseminated encephalomyelitis, and Guillain-Barré syndrome. We report the cases of two interesting patients with confirmed dengue infection who presented with complications of possible central nervous system vasculitis and cranial nerve palsy. The first patient was a 53-year-old previously healthy Singhalese woman who developed acute-onset slurring of speech and ataxia with altered sensorium 1 day after recovery from a critical period of dengue hemorrhagic fever. Subsequent investigations revealed evidence of encephalopathy with brainstem ischemic infarctions. Her clinical picture was compatible with central nervous system vasculitis. She was treated successfully with intravenous steroids and had a full functional recovery. The second patient was a middle-aged Singhalese woman who had otherwise uncomplicated dengue infection. She developed binocular diplopia on day 4 of fever. An ocular examination revealed a convergent squint in the left eye with lateral rectus palsy but no other neurological manifestation. Central nervous system vasculitis due to dengue infection is a very rare phenomenon, and to the best of our knowledge, only one case of central nervous system vasculitis has been reported to date, in a patient of pediatric age. Cranial nerve palsy related to dengue infection is also rare, and only a few cases of isolated abducens nerve palsy have been reported to date. The two cases described in this report illustrate the rare but important central nervous system manifestations of dengue fever and support the fact that the central nervous system is one of the

    The systemic vasculitides are multiorgan diseases where early diagnosis and treatment can significantly improve outcomes. Robust nomenclature reduces diagnostic delay. However, key aspects of current nomenclature are widely perceived to be out of date, these include disease definitions, classific......, classification and diagnostic criteria. Therefore, the aim of the present work was to identify deficiencies and provide contemporary points to consider for the development of future definitions and criteria in systemic vasculitis....

    Full Text Available Abstract Background Secondary systemic vasculitis after posterior spinal fusion surgery is rare. It is usually related to over-reaction of immune-system, to genetic factors, toxicity, infection or metal allergies. Case Description A 14 year-old girl with a history of extended posterior spinal fusion due to idiopathic scoliosis presented to our department with diffuse erythema and nephritis (macroscopic hemuresis and proteinuria 5 months post surgery. The surgical trauma had no signs of inflammation or infection. The blood markers ESR and CRP were increased. Skin tests were positive for nickel allergy, which is a content of titanium alloy. The patient received corticosteroids systematically (hydrocortisone 10 mg for 6 months, leading to total recess of skin and systemic reaction. However, a palpable mass close to the surgical wound raised the suspicion of a late infection. The patient had a second surgery consisting of surgical debridement and one stage revision of posterior spinal instrumentation. Intraoperative cultures were positive to Staphylococcus aureus. Intravenous antibiotics were administered. The patient is now free of symptoms 24 months post revision surgery without any signs of recurrence of either vasculitis or infection. Literature Review Systemic vasculitis after spinal surgery is exceptionally rare. Causative factors are broad and sometimes controversial. In general, it is associated with allergy to metal ions. This is usually addressed with metal on metal total hip bearings. In spinal surgery, titanium implants are considered to be inert and only few reports have presented cases with systemic vasculitides. Therefore, other etiologies of immune over-reaction should always be considered, such as drug toxicity, infection, or genetic predisposition. Purposes and Clinical Relevance Our purpose was to highlight the difficulties during the diagnostic work-up for systemic vasculitis and management in cases of posterior spinal surgery.

    We report a case of isolated periostitis associated with Takayasu arteritis in a 10-year-old boy presenting with calf pain. Radiographs revealed a localized, thick periosteal reaction with irregular margin in the proximal left fibula. MRI revealed irregular thickening with enhancement of the periosteum in the proximal fibula and heterogeneous enhancement along vascular bundles in the calf. Isolated periostitis is a rare skeletal manifestation of systemic vasculitis that could be misdiagnosed as neoplastic or traumatic periosteal reaction. (orig.)

    Full Text Available The systemic Lupus Erythematosus is presented, generally, as a poli articular syndrome, with a long period of fever nephritico or nephrotico; other clinical ways are: neuropsychiatry, vasculitis, etc. They appeared in a progressive manner; but in rare cases as a sickness debutant. It has not being reported in Sancti Spiritus Province patients in which matches the debut of the systemic Lupus Erythematosus with the manifestations of phospholipid syndrome. A Woman with 24 years of age is hospitalized having vasculitis, articular pains, thrombose in her right foot, detecting anticoagulante lupico and possitive Rematoideo factor with periferic pattern diffused in the Inmunoelectroforesis. 5 years later was hospitalized again with poliserositis. She had a positive evolution with a dose in a month of Intacglobin and anticoagulante treatment. Two years later she was hospitalized with articular pains proving she had livedo reticular on her left knee and Raynaud phenomenon on her foot. Beta Prebeta Index and high triglycerides. Lupico anticoagulant positive again. A treatment with Intacglobin and Prednisona was given to the patient with a better clinic without being hospitalized again. There is no evidence (at 17 years of age of a sickness debut of renal dissorder. It is about a Systemic Lupus Eritematoso which debut was a vasculitis and a Phospholipid Syndrome associated.

    One month previously, a 28-year old male underwent an emergency modified Bentall procedure because of Marfan syndrome with acute aortic dissection Stanford Class A. Computed tomography of the chest did not reveal severe graft stenosis of the anastomosis. To explore the cause of anaemia, renal dysfunction and macroscopic haematuria, the patient was tested for antineutrophil cytoplasmic antibody (ANCA)-associated systemic vasculitis (AASV). Antimyeloperoxidase antibodies (MPO)-ANCA and antiproteinase 3 antibodies (PR3)-ANCA were strongly positive. Corticosteroid therapy was applied, followed by cyclophosphamide and azathioprine. In response to treatment, the MPO-ANCA and PR3-ANCA levels gradually decreased, proteinuria was alleviated and haemoglobin levels returned to normal after 6 months. This is the first report to highlight haemolytic anaemia and AASV with Marfan syndrome after surgery for aortic dissection.

    2011-01-01

    Purpose of review To give an overview of recent clinical findings of thromboembolic disease in vasculitis and provide insight into possible explanations of the association between thrombosis and inflammation. Recent findings A high incidence of venous thrombotic events has recently been described in four distinct cohorts of patients with antineutrophil cytoplasmic antibodies-associated vasculitis (AAV), especially during periods of active disease. No factors other than the vasculitis itself have been identified that explain this high occurrence of thrombosis. Several studies have shown an increased rate of thrombosis in Behçet’s disease, with a different clinical presentation than that observed in AAV. Recent laboratory findings provide exciting insights into a bidirectional feedback loop between coagulation and inflammation that may be applicable to vasculitis. Summary Thrombosis is an important clinical manifestation of some types of vasculitis. Better understanding of the association of thrombosis with inflammation in vasculitis might lead to development of clinically useful biomarkers and new approaches to therapy. Additionally, study of the specific factors involved in thrombosis in systemic vasculitis could help explain the role of inflammation in more common settings of venous thrombotic events.

    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. PMID:25500710

  8. Vasculitis mimics.

    Molloy, Eamonn S; Langford, Carol A

    2008-01-01

    There are many disorders that may closely resemble the clinical, radiologic and/or pathologic features of the primary vasculitides. In this review, we focus on recently described and under-recognized syndromes that may mimic vasculitis. Hereditary causes of large-artery aneurysms such as Marfan's syndrome have long been recognized; recent years have seen a greater understanding of the genetics of Marfan's and other such disorders, including Loeys-Dietz syndrome and Ehler-Danlos syndrome type IV. Under-recognized mimics of medium-vessel vasculitis include segmental arterial mediolysis and Grange syndrome. A large number of entities can mimic small-vessel vasculitis. Recent descriptions of antibodies to human neutrophil elastase have provided insight into the occurrence of antineutrophil cytoplasmic antibodies in cocaine-induced midline destructive lesions. The differential diagnosis of cerebral vasculitis can be particularly difficult. Reversible cerebral vasoconstriction syndromes represent an important class of entities that can readily mimic cerebral vasculitis but have a very different management approach and outcome. The diagnosis of vasculitis requires careful assessment of all available clinical, laboratory, radiologic and pathologic information, and consideration of many competing differential diagnoses. Awareness of noninflammatory mimics of vasculitis is essential to avoid unnecessary and potentially harmful treatment with immunosuppressive agents.

    2016-11-01

    The variable symptoms and signs of pulmonary vasculitis are a diagnostic and therapeutic challenge. Vasculitis should be considered in rapidly progressing, severe and unusual manifestations of pulmonary disease. Clinical examination of other organ systems typically affected by vasculitis such as skin and kidney and autoantibody measurements are complementary approaches to manage this situation. Pulmonary involvement is common in small vessel vasculitis including anti-GBM disease (Goodpasture syndrome) and the ANCA-associated vasculitides. Life threatening pulmonary hemorrhage and irreversible damage of other organs, frequently the kidney, are important complications necessitating rapid diagnosis of these conditions.Vasculitides are rare diseases of multiple organs and therapies including biologics are evolving rapidly, requiring cooperation of specialities and with specialized centres to achieve best patient care. All involved physicians should be aware of typical complications of immunosuppressive therapy. © Georg Thieme Verlag KG Stuttgart · New York.

    Primary systemic vasculitides of the young are relatively rare diseases, but are associated with significant morbidity and mortality, particularly if there is diagnostic delay. We provide an overview of paediatric vasculitides with emphasis on key differences in vasculitis presentation and management between children and adults. Significant advances in the field of paediatric vasculitis research include the development of classification criteria and disease outcome tools for paediatric disease; inclusion of paediatric patients in international multicentre randomized controlled trials of therapies in vasculitis; and development of rare disease trial designs for therapeutic trials of paediatric vasculitis. The continuation of unmet needs as well as the exploration of potential therapeutic avenues and considerations in the design of future trials are also discussed. © The Author 2014.

    Levamisole has been increasingly used as an adulterant of cocaine in recent years, emerging as a public health challenge worldwide. Levamisole-associated toxicity manifests clinically as a systemic vasculitis, consisting of cutaneous, hematological, and renal lesions, among others. Purpura retiform, cutaneous necrosis, intravascular thrombosis, neutropenia, and less commonly crescentic nephritis have been described in association with anti-neutrophil cytoplasmic antibodies (ANCAs) and other autoantibodies. Here we report the case of a 49-year-old male who was a chronic cocaine user, and who presented spontaneous weight loss, arthralgia, and 3 weeks before admission purpuric skin lesions in the earlobes and in the anterior thighs. His laboratory tests on admission showed serum creatinine of 4.56 mg/dL, white blood count 3,800/μL, hemoglobin 7.3 g/dL, urinalysis with 51 white blood cells/μL and 960 red blood cells/μL, and urine protein-to-creatinine ratio 1.20. Serum ANCA testing was positive (>1:320), as well as serum anti-myeloperoxidase and anti-proteinase 3 antibodies. Urine toxicology screen was positive for cocaine and levamisole, with 62.8% of cocaine, 32.2% of levamisole, and 5% of an unidentified substance. Skin and renal biopsies were diagnostic for leukocytoclastic vasculitis and pauci-immune crescentic glomerulonephritis, respectively. The patient showed a good clinical response to cocaine abstinence, and use of corticosteroids and intravenous cyclophosphamide. Last serum creatinine was 1.97 mg/dL, white blood cell count 7,420/μL, and hemoglobin level 10.8 g/dL. In levamisole-induced systemic vasculitis, the early institution of cocaine abstinence, concomitant with the use of immunosuppressive drugs in severe cases, may prevent permanent end organ damage and associate with better clinical outcomes.

    This paper evaluates the diagnostic sensitivity and specificity of MR imaging for the detection of cerebral involvement in vasculitis. Seventy-six patient with proved systematic vasculitis and two with isolated cerebral vasculitis were examined. Half of them had central nervous system symptoms. T2-weighted sequences were performed at 2 T in most cases. All but two symptomatic and one-third of the asymptomatic patients showed pathologic changes in the white matter. The distribution and shape of lesions depend on the caliber of the involved vessel. In small-vessel vasculitis, the distribution was mostly subcortical, the average size was 0.5--10 mm, and lesions were predominantly round

    Vasculitis of the mesenteric circulation is an uncommon but life-threatening manifestation of systemic vasculitis. Initial symptoms are frequently non-specific and therefore patients often present to primary care physicians and gastroenterologists with abdominal pain or gastrointestinal bleeding. Given the severity of the conditions associated with mesenteric vasculitis, it is imperative to appropriately diagnose and initiate treatment of suspected cases. This review will focus on diseases commonly associated with vasculitis of the mesenteric vessels. Imaging characteristics and clinical features assisting in diagnosis as well as initial approaches to treatment are emphasized. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Objectives Reports of an association between antineutrophil cytoplasmic antibodies (ANCA) and autoimmune neutropenia have rarely included cases of proven vasculitis. A case of ANCA-associated vasculitis (AAV) with recurrent neutropenia is described and relevant literature on the association between ANCA, neutropenia, and vasculitis is reviewed. Methods Longitudinal clinical assessments and laboratory findings are described in a patient with AAV and recurrent episodes of profound neutropenia from December 2008 – October 2010. A PubMed database search of the medical literature was performed for papers published from 1960 through October 2010 to identify all reported cases of ANCA and neutropenia. Results A 49 year-old man developed recurrent neutropenia, periodic fevers, arthritis, biopsy-proven cutaneous vasculitis, sensorineural hearing loss, epididymitis, and positive tests for ANCA with specificity for antibodies to both proteinase 3 and myeloperoxidase. Antineutrophil membrane antibodies were detected during an acute neutropenic phase and were not detectable in a post-recovery sample, whereas ANCA titers did not seem to correlate with neutropenia. An association between ANCA and neutropenia has been reported in 74 cases from 24 studies in the context of drug/toxin exposure, underlying autoimmune disease, or chronic neutropenia without underlying autoimmune disease. In these cases, the presence of atypical ANCA patterns and other antibodies were common; however, vasculitis was uncommon and when it occurred was usually limited to the skin and in cases of underlying toxin exposure. Conclusions ANCA is associated with autoimmune neutropenia, but systemic vasculitis rarely occurs in association with ANCA and neutropenia. The interaction between neutrophils and ANCA may provide insight into understanding both autoimmune neutropenia and AAV. PMID:21507463

    Vasculitis is a rare disease and clinical symptoms are often unspecific. Accurate and early diagnosis is mandatory in order to prevent complications, such as loss of vision or stroke. Imaging techniques can contribute to establishing a definite diagnosis and to evaluate disease activity and the extent of the disease in various vascular regions. Conventional imaging methods, such as computed tomography (CT) and magnetic resonance (MR) angiography, as well as digital subtraction angiography allow the vessel lumen but not the vessel wall to be depicted. However, vasculitis is a disease which primarily affects the vessel wall, therefore conventional imaging modalities often fail to make a definite diagnosis. Recently black-blood high resolution MR in vivo imaging has been used to visualize cervical and intracranial vasculitis. This review article presents imaging protocols for intracranial and cervical black-blood MR imaging and clinical cases with large vessel vasculitis and vasculitis of the central nervous system. Furthermore the current literature, examples of the most common differential diagnoses of cervical and cranial arteriopathy and the potential of other imaging modalities, such as PET/CT and ultrasound will be discussed.

    2015-04-01

    Vasculitis in connective tissue disease (CTD) is quite rare, it is reported in approximately 10% of patients with CTD; systemic lupus erythematosus (SLE) shows the highest association rate. Vessels of any size may be involved, but mainly small vessels vasculitis is reported. At present the classification of these vasculitis is unsatisfactory. According to the 2012 revised International Chapel Hill Consensus Conference, vasculitides secondary to CTD are a well identified entity and are classified under the category of "vasculitis associated with systemic disease". However only lupus vasculitis and rheumatoid vasculitis are explicitly listed, while the remaining are generically included under the heading "others". Petechiae, purpura, gangrene and ulcers are the most frequent cutaneous manifestations that should investigated in order to rule out potentially dangerous systemic involvement, especially if cryoglobulinemic or necrotizing vasculitis are suspected. This review will focus on the cutaneous involvement in CTD associated vasculitis.

She also complained of painful oral ulcers and few rashes over the face involving the cheeks and forehead since one week. She gave a history of typhoid fever 1 month back, which was associated with difficulty in breathing and swallowing. On examination, vision in both eyes were reduced to counting fingers from 2 metres with pinhole improvement of 6/24. Anterior segment showed periorbital oedema, swollen eyelids along with congestive conjunctiva and grade 2 chemosis. Cornea was clear with no cataractous changes of lens in both the eyes. Pupil was round, regular and reactive for both the eyes. Schirmer's test showed 12 mm and 10 mm wetting of the paper after 5 minutes for right and left eye respectively, which indicated mild dryness of eyes. Fluorescein staining was normal confirming absence of any corneal epithelial defect. Diplopia charting, noncontact tonometry and perimetry findings were within normal limits. On fundoscopy, there was severe arteriolar attenuation along with presence of few cotton wool spots, hard exudates bilaterally and mild tortuosity of vessels in left eye without any signs of vitreous haemorrhage or retinal detachment. Bscan and OCT scanning findings were normal without any signs of haemorrhage or detachment. On fluorescein angiography, there was capillary dropout, vessel wall staining and leakage from vessels. Systemic examination was normal with no palpable lymphadenopathy.

Comparison of patients with and without DV revealed higher frequency of malar rash (80% vs. 53%, p = 0.008, discoid rash (16% vs. 4%, p = 0.017, photosensitivity (76% vs. 45%, p = 0.002 and other cutaneous vasculitides (80% vs. 19%, p 0.05. SLEDAI-2K median, DV descriptor excluded, was significantly lower in patients with DV compared to those without this manifestation [10 (0-28 vs. 14 (0-58, p = 0.004]. Visceral vasculitis or death were not observed in this cSLE cohort. The frequency of cyclophosphamide use (0% vs. 18%, p = 0.014 was significantly lower in the DV group. Conclusion: Our large multicenter study identified clinical DV as one of the rare initial manifestation of active cSLE associated with a mild multisystemic disease, in spite of digital resorption in some of these patients.

    This article addresses the prevalence and relationship between autoinflammatory diseases and vasculitis. Autoimmune diseases (AIDs) are a group of syndromes characterized by episodes of unprovoked inflammation due to dysregulation of the innate immune system. Despite the common occurrence of rashes and other skin lesions in these diseases, vasculitis is reported in only a few. On the other hand, neutrophilic dermatoses are more prevalent. Large vessel vasculitis is reported in patients with Behcet's and Blau's syndromes. Small and medium size vasculitides are reported in familial Mediterranean fever mainly as Henoch-Schonlein purpura and polyarteritis nodosa, respectively. It is rarely described in hyper IgD with periodic fever syndrome, cryopyrin associated periodic syndromes, TNF receptor-associated periodic syndrome, deficiency of interleukin-1 receptor antagonist and pyoderma gangrenosum and acne syndrome. In most AID where bones and skin are mainly involved (CRMO, Majeed syndrome, Cherubism and DITRA) - vasculitis has not been described at all. In AID small vessel vasculitis affects mainly the skin with no involvement of internal organs. In AID, neutrophilic dermatoses are more common and prominent than vasculitis. This may reflect a minor role for interleukin-1 in the pathogenesis of vasculitis. The rarity of vasculitis in AID suggests that in most reported cases its occurrence has been probably coincidental rather than being an integral feature of the disease.

    A 75-year-old woman was admitted to our hospital with rapidly deteriorating consciousness disturbance. She had a 7-year history of rheumatoid arthritis (RA), which had been treated with methotrexate (MTX) and prednisolone. Brain T2-weighted MRI showed diffuse high-intensity lesions in the cerebral subcortical and deep white matter, bilateral basal ganglia and thalamus. A cerebrospinal fluid examination revealed elevated protein levels and positive Epstein-Barr virus (EBV) DNA. Human immunodeficiency virus was negative. Brain biopsy showed perivascular lymphocytic infiltration in the parenchyma and meninx with EBV-encoded small RNA (EBER). Since this case did not fulfill the criteria for chronic active EBV infection (CAEBV), she was diagnosed with Epstein-Barr virus (EBV)-associated vasculitis of the central nervous system. High-dose methylprednisolone, acyclovir, ganciclovir and foscarnet were not effective. Although EBV is a causative agent of infectious mononucleosis (IM), lymphomas and nasopharyngeal carcinomas, vasculitic pathology of the central nervous system with EBV reactivation in the elderly is rare. Immunosuppressive drugs such as steroids and MTX are widely used to treat autoimmune disorders, but may exacerbate the reactivation of EBV. This is the first case of biopsy-proven EBV-positive/HIV-negative vasculitis during the treatment of RA with MTX and steroids. This case indicates that EBV-associated vasculitis needs to be considered as a differential diagnosis of CNS vasculitis. © 2016 Japanese Society of Neuropathology.

    We report a rare case of CNS vasculitis associated with Goodpasture's syndrome in a 34-year-old man, who presented with a seizure and sudden onset of right sided weakness. He also had recurrent hemoptysis of one month's duration. Goodpasture's syndrome is histologically diagnosed by intense linear deposits of IgG along the glomerular basement membrane in both renal and lung tissues. oodpasture's syndrome is a rare disease, characterized by rapidly progressive glomerulonephritis, diffuse pulmonary hemorrhage and circulating antiglomerular basement membrane antibody (anti-GBM antibody). Central nervous system (CNS) manifestations in Goodpasture's syndrome are extremely rare, with only a few cases having been reported in the literature (8 10). Therefore, we present our imaging findings of CNS vasculitis associated with Goodpasture's syndrome, together with a review of the relevant literature. In summary, CNS vasculitis associated with Goodpasture's syndrome is extremely rare. Awareness of the imaging findings, as well as the clinical significance of CNS vasculitis associated with Goodpasture's syndrome, can be helpful in making the correct diagnosis and subsequent management of this rare condition.

    Purpose of review Better biomarkers are needed for guiding management of patients with vasculitis. Large cohorts and technological advances had led to an increase in pre-clinical studies of potential biomarkers. Recent findings The most interesting markers described recently include a gene expression signature in CD8+ T cells that predicts tendency to relapse or remain relapse-free in ANCA-associated vasculitis, and a pair of urinary proteins that are elevated in Kawasaki disease but not other febrile illnesses. Both of these studies used “omics” technologies to generate and then test hypotheses. More conventional hypothesis-based studies have indicated that the following circulating proteins have potential to improve upon clinically available tests: pentraxin-3 in giant cell arteritis and Takayasu’s arteritis; von Willebrand factor antigen in childhood central nervous system vasculitis; eotaxin-3 and other markers related to eosinophils or Th2 immune responses in eosinophilic granulomatosis with polyangiitis (Churg-Strauss syndrome); and MMP-3, TIMP-1, and CXCL13 in ANCA-associated vasculitis. Summary New markers testable in blood and urine have the potential to assist with diagnosis, staging, assessment of current disease activity, and prognosis. However, the standards for clinical usefulness, in particular the demonstration of either very high sensitivity or very high specificity, have yet to be met for clinically relevant outcomes.

    2015-01-01

    Objective To quantify the occurrence of features of vasculitis that initially present after diagnosis in 6 types of primary vasculitis. Methods Standardized collection of data on 95 disease manifestations in 6 vasculitides, including granulomatosis with polyangiitis (Wegener's, GPA), microscopic polyangiitis (MPA), eosinophilic granulomatosis with polyangiitis (Churg-Strauss, EGPA), polyarteritis nodosa (PAN), giant cell arteritis (GCA), and Takayasu's arteritis (TAK), was performed within a set of multicenter longitudinal, observational cohorts. For each form of vasculitis, the frequency of disease-specific manifestations at diagnosis was compared to the cumulative frequency of each manifestation. The percentage of patients who initially developed “severe” manifestations after diagnosis, defined as organ- or life-threatening in the small and medium vessel vasculitides (GPA, MPA, EGPA, PAN) and as ischemic/vascular in the large vessel vasculitides (GCA, TAK), was reported. Results Out of 838 patients with vasculitis, 490 (59%) experienced ≥ 1 new disease manifestation after diagnosis. On average, patients with vasculitis experienced 1.3 new manifestations after diagnosis (GPA - 1.9, MPA - 1.2, EGPA - 1.5, PAN - 1.2, GCA - 0.7, TAK - 1.0). New severe manifestations occurred after diagnosis in 224 (27%) out of 838 patients (GPA - 26%, MPA - 19%, EGPA - 21%, PAN - 23%, GCA - 24%, and TAK - 44%). Timing of onset of new manifestations was not significantly associated with disease duration. Conclusion A majority of patients with vasculitis develop new disease features after diagnosis, including a substantial number of new, severe manifestations. Ongoing assessment of patients with established vasculitis should remain broad in scope. PMID:23908447

    3D-TOF-MRA and DSA are 2 available tools to demonstrate neurovascular involvement in primary central nervous system vasculitis. We aimed to compare the diagnostic concordance of vessel imaging using 3D-TOF-MRA and DSA in patients with primary central nervous system vasculitis. We retrospectively identified all patients included in the French primary central nervous system vasculitis cohort of 85 patients who underwent, at baseline, both intracranial 3D-TOF-MRA and DSA in an interval of no more than 2 weeks and before treatment initiation. Two neuroradiologists independently reviewed all 3D-TOF-MRA and DSA imaging. Brain vasculature was divided into 25 arterial segments. Concordance between 3D-TOF-MRA and DSA for the identification of arterial stenosis was assessed by the Cohen κ Index. Thirty-one patients met the inclusion criteria, including 20 imaged with a 1.5T MR unit and 11 with a 3T MR unit. Among the 25 patients (81%) with abnormal DSA findings, 24 demonstrated abnormal 3D-TOF-MRA findings, whereas all 6 remaining patients with normal DSA findings had normal 3D-TOF-MRA findings. In the per-segment analysis, concordance between 1.5T 3D-TOF-MRA and DSA was 0.82 (95% CI, 0.75-0.93), and between 3T 3D-TOF-MRA and DSA, it was 0.87 (95% CI, 0.78-0.91). 3D-TOF-MRA shows a high concordance with DSA in diagnostic performance when analyzing brain vasculature in patients with primary central nervous system vasculitis. In patients with negative 3T 3D-TOF-MRA findings, the added diagnostic value of DSA is limited. © 2017 by American Journal of Neuroradiology.

    The skin is a common target of small vessel vasculitis, with a wide assortment of pathological changes. This condition is usually associated to systemic diseases. To report the clinical and pathological features of patients with cutaneous small vessel vasculitis. A retrospective review of 32 patients with a pathological diagnosis of cutaneous vasculitis. Seventy two percent of patients were women. Cutaneous lesions were mainly located in the lower limbs (94%). The most common lesion was palpable purpura (62%). Connective tissue diseases and systemic vasculitis were the most commonly associated systemic diseases. Palpable purpura is the most common manifestation of cutaneous small vessel vasculitis, that is usually associated to connective tissue diseases or systemic vasculitis.

    The incidence of primary systemic vasculitides varies among different geographic regions and ethnic origins. The aim of this study was to examine the incidence rates of vasculitides in the Jerusalem Jewish population, and to examine possible trends in incidence rates over a 20-year period. The clinical databases of inpatients at the 2 medical centers in Jerusalem were searched for patients with vasculitis diagnosed between 1990-2009. Individual records were then reviewed by one of the authors. The significance of trends in incidence rates throughout the study period was evaluated by Pearson correlation coefficient. The average annual incidence rate of polyarteritis nodosa was 3.6/million adults (95% CI 1.6-4.7). Incidence rates did not change significantly during this period (r = 0.39, p = 0.088). The incidence of granulomatosis with polyangiitis (GPA) was 4.1 (2.2-5.9) for the whole period, during which it increased significantly (r = 0.53, p Jerusalem are in the lower range of global incidence rates. While GPA and MPA incidence are increasing, GCA incidence is decreasing.

    We report on a patient with Graves' disease with radiation retinopathy caused by low-dose irradiation and antithyroid drug-induced antineutrophil cytoplasmic antibody (ANCA)-positive vasculitis. A 38-year-old woman with Graves' disease presented with bilateral blurred vision, micro-aneurysms, telangiectasia, and macular edema. The patient was examined by ophthalmoscopy and fluorescein angiography, and radiation retinopathy was diagnosed. The patient had been treated with low-dose irradiation for her Graves' ophthalmopathy a few years earlier. She also had ANCA-positive vasculitis induced by the antithyroid drug (propylthiouracil, PTU) that had been prescribed for her at that time. Because of multiple avascular areas on both retinas, she was treated by intensive retinal photocoagulation to control progressive retinopathy. The radiation doses used to treat Graves' disease ophthalmopathy are low. Nevertheless, there is still a risk of radiation retinopathy developing in patients with PTU-induced ANCA-positive vasculitis. (author)

    Objectives Childhood-onset systemic lupus erythematosus (cSLE) is a multisystemic autoimmune disease characterized by inflammatory organ damage by means of vasculitis. Pentraxin-3 (PTX3) is expressed locally at the sites of inflammatory processes, predominantly from endothelial cells. In adult studies, PTX3 has shown to be an indicator of active vasculitis both in large-vessel and small-vessel vasculitides, as well as in SLE. Moreover, in SLE it has found to be correlated with disease activity, and with some of the clinical manifestations and laboratory parameters. We aimed to ascertain if PTX3 might be a significant mediator in cSLE and if it might indicate active vasculitis during the course of the disease. Methods Serum PTX3 levels were measured in 76 patients with cSLE and 41 healthy subjects. We have investigated its relation with disease activity, damage, clinical features, laboratory parameters and medications. Results Serum levels of PTX3 were found to be increased in cSLE compared to healthy controls (mean ± SD; 10.6 ± 8.2 ng/mL vs 2.7 ± 1.3 ng/mL, p Lupus International Collaborating Clinics/American College of Rheumatology Damage Index), ESR, CRP, procalcitonin levels, anti-ds DNA antibody, anticardiolipin antibodies was not detected. Conclusions Patients with cSLE have increased levels of serum PTX3 compared to healthy controls. Thus, serum PTX-3 level might be a significant mediator in cSLE. Apart from these, the results support that PTX3 reflects active cutaneous vasculitis in cSLE and correlates with disease activity.

    Commentary on « Cerebral vasculitis mimicking intracranial metastatic progression of lung cancer during PD-1 blockade » by Läubli H et al., J Immunother Cancer. 2017;5:46.The authors diagnosed a cerebral tumor-like lymphocytic vasculitis associated with anti-endothelial cell auto-antibodies secondary to anti-PD-1 therapy, treated by surgical resection and corticosteroids. We thought that this diagnosis should be discussed for at least two reasons. First, etiological explorations were not sufficient. Second, the diagnostic of radionecrosis should also be discussed.

    Vasculitides includes a heterogeneous group of disorders with the common histologic findings of vascular wall inflammation. Systemic or localized disease (eg, renal vasculitis) has serious consequences. The incidence of isolated gynecologic vasculitis diagnosed on pathology specimens and its significance is little known. We performed a 20 year retrospective review including 53 cases with vasculitis diagnosis affecting the female genital tract identified in pathology reports. None had prior symptoms or were diagnosed with generalized vasculitis, while one patient had prior diagnosis of fibromyalgia. Most patients presented with abnormal bleeding and were treated for conditions unrelated to vasculitis. The different types of vasculitis were: predominantly lymphocytic (nonspecific) 30 cases, necrotizing 17 cases and granulomatous 6 cases. Only 2 patients had additional serologic tests. None of the patients with isolated gynecologic vasculitis received corticosteroids or additional treatment related to the vasculitis. None of the patients developed systemic vasculitis at follow-up (2 months-19.5 years; mean, 5.5 years). Isolated gynecologic vasculitis diagnosed on pathology slides is rarely associated with systemic vasculitis. Potential isolated gynecologic vasculitis causes include: previous surgical interventions and vascular inflammation secondary to local neoplasm. In almost all cases, clinicians did not perform a thorough laboratory analysis to exclude systemic vasculitis and therapy was not required in any case, suggesting minimal clinical significance.

    Background: The prognosis of systemic vasculitis, for instance Wegener's granulomatosis (WG), was greatly improved by the introduction of immunosuppressive treatment. However, relapses are frequent and predictors are scarce. 111 In-leukocytes have been found to indicate unknown manifestations of WG and to predict later relapse. We prospectively investigated the value of 99m Tc-Exametazime ( 99m Tc-HMPAO)-labeled leukocytes with regard to specific patterns and for their usefulness in the follow-up of patients with WG. Methods: The vasculitis group consisted of 8 patients with WG and 2 with idiopathic necrotizing glomerulonephritis (ING). Seven patients with different inflammatory diseases served as controls. Leukocyte labeling with 99m Tc-HMPAO was done using a slightly modified Hammersmith protocol. Cell viability after labeling was verified in vivo by the exclusion of early lung and splenic uptake and in vitro by means of propidium iodide and FACS analysis. Static gamma camera images from the head, chest, abdomen, and pelvis were obtained up to 18 hours after injection of approximately 300 MBq 99m Tc-HMPAO-labeled leukocytes. Scintigrams were analyzed visually; for semiquantitative analysis ROIs were drawn over the nasal region, the right lung, kidneys, and liver. Results: Increased nasal leukocyte accumulation was found in 7/8 patients with WG and in 2/2 patients with ING. Of 2 patients who had a relapse 6 months later, one presented with, and one without nasal uptake. The kidney/liver ratio was higher in controls (0.24 ± 0.07 vs. 0.37 ± 0.11, p 99m Tc-HMPAO leukocyte scintigraphy failed to indicate or exclude a later relapse and is therefore not suitable as a diagnostic tool in the management of patients with systemic vasculitis.

    Pulmonary hemorrhage (PH) occurs in 2-5% of SLE patients, and is associated with a high mortality rate (79-90%). Diagnostic criteria for this complication include: 1) Pulmonary infiltrates, with at least ¾ of lung tissue involved in a chest x ray, 2) Acute respiratory failure, 3) A decrease of 3g/dL or more in hemoglobin levels. PH might lead to organized pneumonia, collagen deposition, and pulmonary fibrosis which in time might cause changes in pulmonary function tests with either restrictive or obstructive patterns. To evaluate the existence of abnormalities in pulmonary function tests after a PH episode. We included patients with SLE and primary vasculitis that developed PH. During the acute episode, we measured SLEDAI in SLE patients, five factor score in microscopic polyangiitis (MPA) and Birmingham Vasculitis Activity Store (BVAS) in granulomatosis with polyangiitis (GPA) (Wegener). We determined the number of PH events, treatment, and ventilator assistance requirements and correlated its association with abnormal pulmonary function tests. We included 10 patients, 7 with SLE, 2 with MPA and 1 with GPA (Wegener). The mean activity measures were: SLEDAI 20.4 ± 7.5, FFS 2, and BVAS 36. Treatment consisted in methylprednisolone (MPD) in 3 patients, MPD plus cyclophosphamide (CY) in 6 patients, and MPD, CY, IV immunoglobulin, and plasmapheresis in one patient. Five patients required ventilatory support. We found abnormalities in pulmonary function tests in 8 patients, three had an obstructive pattern and five a restrictive pattern; 2 patients did not show any change. We did not find a significant association with any of the studied variables. PH might cause abnormalities in pulmonary function tests and prolonged immunosuppressive treatment could be required.

    The diagnosis and management of Wegener's granulomatosis and microscopic polyarteritis are complicated by the lack of specific diagnostic tests. The diagnostic performance of a solid-phase radioimmunoassay, which detects the autoantibodies against neutrophil cytoplasm present in these disorders, was assessed in a prospective study of patients with suspected vasculitis and/or rapidly progressive nephritis. The assay had a sensitivity and specificity of 96% when carried out in combination with a specific inhibition stage and indirect immunofluorescence staining of alcohol-fixed normal neutrophils.

    A 12-year-old Indian boy presented with acute and severe vision loss in his right eye. He was being treated for scalp alopecia areata and rashes behind the ears and above the brow. The eye examination revealed unilateral hemorrhagic retinal vasculitis. The lab work was normal except for a positive HLA-B27 result. The patient was treated with intravitreal bevacizumab (Avastin; Genentech, South San Francisco, CA) and systemic immunosuppression. The retinal vasculitis improved with treatment, but visual acuity only mildly improved. The alopecia areata also improved with systemic immunosuppression.

    To review recent evidence for infection rates in patients with systemic vasculitides, the role of specific infectious agents in the pathogenesis of vasculitis and recent breakthroughs in the treatment of virus-associated vasculitides. In well designed recent studies, infections were found to be common during the first 6-12 months in patients with anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitides (AAV) and giant cell arteritis (GCA) and to contribute significantly to increased mortality during this period. New therapeutic schemes with lower cyclophosphamide doses and shorter corticosteroid courses were associated with decreased infectious rates in elderly patients with AAV whereas a prednisone dose greater than 10 mg/day at the end of the first year were associated with increased infectious-related mortality in patients with GCA. Recently, a potential role for varicella zoster virus in GCA pathogenesis has been proposed but more data are needed in order to establish a causal relationship. Finally, preliminary data show excellent short-term efficacy and safety of the new, interferon-free, oral antiviral agents in the treatment of hepatitis C virus-associated cryoglobulinemic vasculitis. Infections continue to be one of the main causes of mortality in patients with systemic vasculitides, emphasizing the need for safer immunosuppressive therapies and appropriate prophylaxis.

    Cerebral vasculitis can have a variety of origins. Furthermore, there are no vasculitis-specific symptoms or imaging signs and vasculitis of the CNS can mimic many other neurological diseases, which require different treatment approaches. Thus, the clinical and radiological diagnosis of cerebral vasculitis is challenging. Magnetic resonance imaging (MRI) and MR angiography (MRA) should be the radiological imaging methods of choice to assess the degree of parenchymal damage and to detect vessel wall changes. If the results are unclear digital subtraction angiography (DSA) should be pursued in order to also detect changes in medium sized vessels. Vasculitis of small vessels cannot be detected by vascular imaging and requires brain or leptomeningeal biopsy. In this review we present the current diagnostic approach and a variety of imaging findings in cerebral vasculitis and discuss the main radiological differential diagnoses. (orig.) [de

    Vasculitis is defined as an inflammatory process involving blood vessels, and can lead to destruction of the vascular wall and ischemic damage to the organs supplied by these vessels. The lung is commonly affected. A number of attempts have been made to classify and organize pulmonary vasculitis, but because the clinical manifestations and pathologic features of the condition overlap considerably, these afforts have failed to achieve a consensus. We classified pulmonary vasculitis as belonging to either the angitiis-granulomatosis group, the diffuse pulmonary hemorrhage with capillaritis group, or 'other'. Characteristic radiographic and CT findings of the different types of pulmonary vasculitis are illustrated, with a brief discussion of the respective disease entities

    Vasculitis is more often a disease of women beyond their reproductive years, leaving the challenges of pregnancy management difficult to study. Pregnancy complications, including pregnancy loss and preterm birth, are higher among women with all forms of vasculitis. It seems that controlling the disease before pregnancy may improve the chances of pregnancy success. Many medications used for vasculitis are considered low risk in pregnancy, including prednisone, colchicine, azathioprine, and tumor necrosis factor inhibitors. Cyclophosphamide, methotrexate, and mycophenolate mofetil should be avoided in pregnancy. Controlling disease with low-risk medications may allow women with vasculitis to have the pregnancies they desire. Copyright © 2017 Elsevier Inc. All rights reserved.

    Hypocomplementemic urticarial vasculitis syndrome (HUVS) is a rare autoimmune disease characterized by multiple organ system involvement, including renal disease, with low complement levels. We report the case of a 31-year-old woman who presented with nonspecific symptoms including fatigue, diarrhea, macular rash and abdominal pain with acute renal failure leading to end-stage kidney disease. Laboratory results showed hematuria, nephrotic range proteinuria, worsening creatinine and low C1q levels. Left kidney biopsy showed proliferative glomerulonephritis with crescent formation. She was treated with 6 months of intravenous cyclophosphamide, followed by 2 doses of intravenous rituximab (1g each), thereafter maintained on mycophenolate mofetil and glucocorticoid-based therapy. She experienced a full recovery of renal function after 12 months of dialysis dependence. Hypocomplementemic urticarial vasculitis syndrome with crescentic glomerulonephritis is a rare disease with only 5 other reported cases in literature. In our case, we document a delayed but excellent renal recovery during a 2-year follow-up. Copyright © 2018 Southern Society for Clinical Investigation. Published by Elsevier Inc.

    To evaluate TOF 3D magnetic resonance angiography (MRA) of the intracranial arteries in patients with vasculitis or vasculitis-like benign angiopathy of the central nervous system (CNS). Method: The results of MRA in 20 patients with clinically and radiographically proven vasculitis (17/20) or vasculitis-like benign angiopathy (3/20) of the CNS were retrospectively analysed. Patients with hyperintense lesions of more than 3 mm on T{sub 2}-weighted MRI images were included in this trial. An inflammatory, embolic, neurodegenerative or metastatic origin of these lesions was excluded by extensive clinical studies. For the MR-examination a TOF 3D FISP sequence was used on a 1.5 T imager. Results: MRA showed characteristic changes for vasculitis or angiopathy in 15 of 20 patients (75%). Conclusions: In patients suspected of having a vasculitis or vasculitis-like angiopathy, MRA is recommended as a non-invasive modality. If the results of MRI and extensive clinical studies are carefully correlated, MRA may substitute conventional angiography in cases with typical vascular changes. (orig.)

    2015-03-01

    Mesenteric vasculitis is a rare diagnosis, but it comprises a group of disorders that may have devastating manifestations. It is often difficult to diagnose using clinical symptoms and biomarkers. Vascular imaging often provides the best opportunity for the noninvasive diagnosis of vasculitis and obviates the need for performing a biopsy. The medical management of vasculitis involves controlling the inflammatory process with the use of steroids or other immunosuppressants, but medical therapy does not consistently provide regression of the vascular changes (ie, aneurysms or vascular occlusions) seen at the time of the initial diagnosis. Operative management remains the mainstay of therapy for focal occlusive or aneurysms, but the treatment options for multifocal disease remain challenging. Endovascular treatment is increasingly being used as a first line of treatment for symptomatic vasculitis. Interventionalists should be familiar with the indications and outcomes associated with the various therapeutic options for mesenteric vasculitis-associated occlusive disease and aneurysms.

    The review aims to summarize the recent findings in vasculitis that may have an impact in our understanding or management of these diseases. We are learning more about monogenic diseases that closely mimic the pediatric vasculitides. Deficiency of adenosine deaminase 2 can present with a polyarteritis nodosa (PAN)-like picture and should be included in the differential of all pediatric cases of PAN with a family history or in cases with early stroke, or in cases resistant to conventional therapy. Mutations in tumor necrosis factor α-induced protein 3 results in a disease that can present as Behçet disease called haploinsufficiency of A20. In fact, these patients would also fulfill the existing criteria for PAN and Behçet disease, respectively. Additional advances in Behçet disease pathogenesis come from a large genetic study of Turkish Behçet disease using data obtained from genotyping using the Immunochip. This confirmed the HLA-B-51 locus as the most significant association and identified new risk loci. Large Iranian and Japanese cohorts were used as replication cohorts. Best treatment of pediatric vasculitis remains a challenge as we continue to lack controlled studies. There are new reports in treatment on Henoch-Schönlein purpura/Immunoglobulin A vasculitis which is one of our most frequent childhood vasculitides. Small series of new treatments for central nervous system vasculitis and Takayasu disease will also be summarized. Diagnostic criteria have been reassessed in pediatric Behçet disease as well as adult and childhood forms of antineutrophil cytoplasmic antibodies-positive vasculitis. The new pathways defined in monogenic diseases may help us better understand the pathogenesis and may help us design more targeted therapy. Although pediatric cases are being increasingly recognized, the relative rarity of the diseases presents an obstacle for studies. Thus, we can reach conclusive results for their management through multicenter studies only.

    2013-01-01

    Full Text Available Abstract Introduction Anti-neutrophil cytoplasmic antibody-associated vasculitis has been associated with many drugs and it is a relatively rare side effect of the antihypertensive drug hydralazine. The diagnosis and management of patients who have anti-neutrophil cytoplasmic antibody-associated vasculitis may be challenging because of its relative infrequency, variability of clinical expression and changing nomenclature. The spectrum of anti-neutrophil cytoplasmic antibody-associated vasculitis is wide and can be fatal. This case documents a 62-year-old woman who presented with hydralazine-induced anti-neutrophil cytoplasmic antibody-positive renal vasculitis with a puzzling cutaneous rash. Case presentation We report a rare case of hydralazine-induced anti-neutrophil cytoplasmic antibody-associated vasculitis in a 62-year-old Caucasian woman who presented with a vasculitic syndrome with a sore throat, mouth ulcers and otalgia after several months of constitutional symptoms. She then proceeded to develop a rash over her right lower limb. Clinically, the rash had features to suggest Sweet’s syndrome, but also had some appearances consistent with embolic phenomena and did not have the appearance of palpable purpure usually associated with cutaneous vasculitis. Differential diagnoses were hydralazine-associated Sweet’s syndrome, streptococcal-induced cutaneous eruption or an unrelated contact dermatitis. A midstream urine sample detected glomerular blood cells in the setting of anti-neutrophil cytoplasmic antibody-positive renal vasculitis and Streptococcus pyogenes bacteremia. A renal biopsy revealed a pauci-immune, focally necrotizing glomerulonephritis with small crescents. Her skin biopsy revealed a heavy neutrophil infiltrate involving the full thickness of the dermis with no evidence of a leucocytoclastic vasculitis, but was non-specific. She was initially commenced on intravenous lincomycin for her bloodstream infection and subsequently

    Full Text Available Wegener’s (granulomatosis with polyangiitis, GPA and Churg-Strauss (eosinophilic polyangiitis, EPA vasculitis are treated as a single variant of systemic necrotizing granulomatosis vasculitis, associated with anti-neutrophil cytoplasmic antibodies (ANCA. There is an urgent need for further study of articular syndrome in patients with ANCA-SV. Objective: to evaluate the incidence and nature of the lesion of the joints at GPA and EPA, connection with extra-articular signs of the disease. Material and methods. The study involved 58 patients with ANCA-SV, among which there were 28 patients with GPA (16 men and 12 women aged from 17 to 70 years old and 30 with EPA (14 men and 16 women aged 19–70 years old.The average duration of the disease in the first and second groups was 4 years and 11 years, respectively. I, II and III degree activity of the GPA were in the ratio 1 : 6 : 7 and in the cases of EPA — 1 : 3 : 4. The lung pathology was diagnosed in all cases with EPA, in patients with GPA — in 68 % of cases. In addition, 2.3 times less frequently cutaneous syndrome was detected. Results. The lesion of the joints in the form of arthritis or arthralgia occurs in 1/2 of the number of patients with granulomatous ANCA-SV in the ratio of HPA to EPA as 1 : 2, which is associated with the severity of extra-articular manifestations of disease, and in cases of EPA — with the level of antibodies to proteinase-3. Patients with EPA significantly more frequently had lesions of the maxillary joints, digital joints of foot, ankle, metatarsophalangeal, hip, sacroiliac and vertebral, and the last 4 were not diagnosed in patients with HPA. Epiphyseal osteoporosis, subchondral sclerosis, osteocytes, artrocalcinosis and changes of the menisci horns of the knee-joints were observed only at EPA. Conclusions. The severity of arthropathy prevails in EPA, compared to GPA, that is associated with great inflammatory degenerative changes of the articular, but intra

    Vasculitis may be caused by infection, medications, systemic diseases, malignancy, or occur as an idiopathic condition. In cases of drug-induced vasculitis, it is essential to identify and discontinue the culprit medication. As novel agents are approved through clinical trials, some rare events, including vasculitis, may not become apparent until wider use, and rigorous post-marketing surveillance for new medications is important. Physicians should consider drug-induced vasculitis on the differential for all new vasculitis diagnoses, and if the potential triggering medication is a novel medication, it is essential to rigorously investigate the potential for emerging cases of medication-associated vasculitis in all available scientific literature.

    In this uncontrolled study 15 patients with ANCA-associated systemic vasculitis, who were poor responders to conventional therapy, were treated with single or multiple courses of intravenous immunoglobulin (IVIG), 30 g/day over 5 days. Clinical and serological evaluation was performed before and 4 weeks after IVIG. Six of the 15 patients experienced clinically significant benefit from IVIG. Improvement was confined to single organ manifestations (skin, ENT findings), no improvement was seen with conjunctivitis and scleritis, pericarditis or nephritis. No patient experienced complete remission after IVIG. Repeated courses of IVIG at 4-week intervals were no more effective than single courses. In six anti-proteinase 3 (PR3)-positive patients pretreatment sera were incubated with F(ab')2 fragments of the IVIG preparation in vitro to measure the inhibitory effect of IVIG on anti-PR3 activity. An inhibition of anti-PR3 activity by 25-70% was observed; this did not correlate with clinical effects. Approximately 40% of patients benefited from IVIG treatment, though complete remission of disease activity did not occur. Neither clinical characteristics nor the inhibitory effect of the IVIG preparation on serum anti-PR3 activity in vitro predicted clinical response to this treatment modality.

    Vasculitis is an accumulation of inflammatory leucocytes in the blood vessels with reactive damage to mural structures. Isolated vasculitis of the gastrointestinal tract without systemic involvement is rare. We report a unique case of a female patient who presented with abdominal pain, and was found, on serology, to have elevated inflammatory markers without autoantibodies. A computed tomography scan of the abdomen and pelvis was suggestive of vasculitis of the hepatic artery. To the best of our knowledge, this is the first case, to date, of vasculitis of hepatic artery. © 2015 Marshfield Clinic.

    Vasculitides represent a group of relatively rare systemic inflammatory diseases of the blood vessels. Despite recent progress in understanding the genetic basis and the underlying pathogenic mechanisms in vasculitis, the etiology and pathogenesis of vasculitis remain incompletely understood. Epigenetic dysregulation plays an important role in immune-mediated diseases, and the contribution of epigenetic aberrancies in vasculitis is increasingly being recognized. Histone modifications in the PR3 and MPO gene loci might be mechanistically involved in the pathogenesis of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis. Similarly, other studies revealed important epigenetic contribution to other vasculitides, including Kawasaki disease and IgA vasculitis. More recently, genome-wide epigenomic studies have been performed in several vasculitides. A recent genome-wide DNA methylation study uncovered an important role for epigenetic remodeling of cytoskeleton-related genes in the pathogenesis of Behçet's disease and suggested that reversal of some of these DNA methylation changes associates with disease remission. Genome-wide DNA methylation profiling characterized the inflammatory response in temporal artery tissue from patients with giant cell arteritis and showed increased activation of calcineurin/nuclear factor of activated T cells (NFAT) signaling, prompting the suggestion that a specific calcineurin/NFAT inhibitor that is well tolerated and with the added beneficial anti-platelet activity, such as dipyridamole, might be of therapeutic potential in giant cell arteritis. While epigenetic studies in systemic vasculitis are still in their infancy, currently available data clearly indicate that investigating the epigenetic mechanisms underlying these diseases will help to better understand the pathogenesis of vasculitis and provide novel targets for the development of disease biomarkers and new therapies.

    Vasculitides secondary to connective tissue diseases are classified under the category of 'vasculitis associated with systemic disease' in the revised International Chapel Hill Consensus Conference (CHCC) nomenclature. These secondary vasculitides may affect any of the small, medium or large vessels and usually portend a poor prognosis. Any organ system can be involved and the presentation would vary depending upon that involvement. Treatment depends upon the type and severity of presentation. In this review, we describe secondary vasculitis associated with rheumatoid arthritis, systemic lupus erythematosus, sarcoidosis, relapsing polychondritis, systemic sclerosis, Sjogren's syndrome and idiopathic inflammatory myositis, focusing mainly on recent advances in the past 3 years.

    The case presented illustrates the diagnostic dilemma off neurological involvement in Behcet's disease and other inflammatory diseases. 'Psychiatric' symptoms were present for 2 years without abnormalities on SPECT or MRI and without CSF pleocytosis. Even at the time of fitting, no CSF abnormalities were observed. The preceding psychiatric presentations may have been due to cerebral vasculitis that was exacerbated by withdrawal of steroids. Magnetic resonance imaging is currently the most sensitive imaging modality. Lesions are usually in the brainstem, cerebellum, basal ganglia region or periventricular white matter, and the pons and the mesencephalon are commonly affected. In our patient there was no diencephalic or brainstem involvement. The inflammatory process can appear as a very large lesion, with gadolinium enhancement and significant mass effect, as in our patient. Brain magnetic resonance imaging. Postgadolinium-diethylenetriamine pentaacetic acid, axial image shows two large lesions in the right frontal lobe, with the larger, posterior lesion demonstrating vivid ring enhancement. A central nodule is isodense, with the cerebral white matter within the larger lesion. Surrounding low T 1 signal involves the hemispheric white matter without cortical extension and is consistent with vasogenic oedema. Minor mass effect is demonstrated with bowing of the anterior falx cerebri to the left. Biopsy shows prominent fibrinoid necrosis in small calibre postcapillary venules and cerebral white matter. There are surrounding acute and chronic inflammatory cells and nuclear debris, consistent with vasculitis

    Abstract The aim of the study was to report the clinical, biological, and pathological characteristics of patients with glomerulonephritis (GN) secondary to systemic lupus erythematosus (SLE)/antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) overlap syndrome. A nationwide survey was conducted to identify cases of SLE/AAV overlap syndrome. Data were collected from SLE and AAV French research groups. Inclusion criteria were diagnosis of both SLE and AAV according to international classification criteria and biopsy-proven GN between 1995 and 2014. Additional cases were identified through a systematic literature review. A cohort of consecutive biopsy-proven GN was used to study the prevalence of overlapping antibodies and/or overlap syndrome. The national survey identified 8 cases of SLE/AAV overlap syndrome. All patients were female; median age was 40 years. AAV occurred before SLE (n = 3), after (n = 3), or concomitantly (n = 2). Six patients had rapidly progressive GN and 3/8 had alveolar hemorrhage. All patients had antinuclear antibodies (ANA); 7/8 had p-ANCA antimyeloperoxidase (MPO) antibodies. Renal biopsies showed lupus nephritis (LN) or pauci-immune GN. Remission was obtained in 4/8 patients. A literature review identified 31 additional cases with a similarly severe presentation. In the GN cohort, ANCA positivity was found in 30% of LN, ANA positivity in 52% of pauci-immune GN, with no correlation with pathological findings. The estimated prevalence for SLE/AAV overlap syndrome was 2/101 (2%). In patients with GN, SLE/AAV overlap syndrome may occur but with a low prevalence. Most patients have an aggressive renal presentation, with usually both ANA and anti-MPO antibodies. Further studies are needed to assess shared pathogenesis and therapeutic options. PMID:27258503

    Single-organ vasculitis has been reported to affect the skin, kidneys, central nervous system, peripheral nerves, genitourinary tract, calf muscles, aorta, coronary arteries, retina, or gastrointestinal tract. However, isolated pulmonary vasculitis is a very rare entity. Our aims were to describe a case of localized pulmonary vasculitis affecting medium-sized vessels and review the literature. A patient with localized pulmonary vasculitis affecting medium-sized vessels that presented as pulmonary arterial hypertension is described. A MEDLINE database search of cases with localized pulmonary vasculitis was also conducted. A 30-year-old man presented with pulmonary hypertension due to isolated pulmonary medium-sized vessel vasculitis that was confirmed histologically. Initially he responded to corticosteroids and vasodilator treatment, but therapy eventually lost efficacy. Treatment with rituximab was not effective, and as the clinical situation worsened, lung transplant was performed. Isolated large pulmonary vessel disease, often related to Takayasu disease or giant cell arteritis, may present as pulmonary artery hypertension, thus mimicking chronic thromboembolic disease. Medium- and small-vessel pulmonary vasculitis usually develops in the context of a systemic disease. Some cases of isolated small-vessel vasculitis have been reported presenting as diffuse alveolar hemorrhage. In contrast, our case developed pulmonary artery hypertension secondary to medium-sized vessels vasculitis. To our knowledge, this is the first case of lung transplantation in isolated pulmonary vasculitis. Pulmonary isolated vasculitis is a rare cause of pulmonary hypertension but it must be taken into consideration after more common disorders are excluded. Copyright © 2014 Elsevier Inc.

    Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis of medium-sized visceral vessels. However, cutaneous arteritis (CA) and gastrointestinal (GI) vasculitis are forms of single-organ vasculitis having indistinguishable histopathologic findings from PAN. The aim of this study was to evaluate and compare the clinical characteristics, treatment, and outcomes of patients with systemic PAN, CA, and GI vasculitis. Retrospective cohorts were assembled, consisting of patients with PAN, CA, and GI vasculitis between 1980 and 2014. The demographics, clinical characteristics, treatment, and outcomes of patients were abstracted from medical records. We included 48 patients with PAN, 41 patients with CA, and 19 patients with GI vasculitis. The disease of 1 patient evolved from CA to systemic PAN during the disease course. At diagnosis, 94% of patients with PAN, 93% of patients with CA, and 67% of patients with GI vasculitis were treated with glucocorticoids. Additional immunosuppressive agents were used in 67% of PAN, 37% of GI vasculitis, and 32% of CA cases. The 5-year cumulative relapse rate was 45.2% in CA, and only 9.6% in PAN during a followup of approximately 6 years. No deaths were observed in the CA group. The survival rate at 10 years was 66% in the PAN group and 61% in the GI vasculitis group. Systemic PAN, CA, and GI vasculitis take different clinical courses and therefore may be different diseases, rather than existing on a spectrum of the same disease. Progression of CA to systemic PAN is very rare. Relapse risk is low during followup in PAN. Patients with CA have a higher relapse rate than those with systemic PAN, possibly due to less use of immunosuppressive therapy in CA. © 2016, American College of Rheumatology.

    Cryoglobulinemic vasculitis is a rare entity. Although it has been reported in diffuse systemic sclerosis, it has not been reported in calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly and telangiectasia (CREST) syndrome. We report a patient with cryoglobulinemic vasculitis with CREST syndrome who did not have typical clinical features of vasculitis. This 58-year-old woman presented with mild generalized weakness and a diagnosis of CREST syndrome, which included Raynaud's syndrome, dysphagia and telangiectasias. She was positive for serum cryoglobulins, which led to a sural nerve biopsy. The biopsy results were consistent with cryoglobulinemic vasculitis. Cryoglobulinemic vasculitis has not been previously reported in CREST syndrome to our knowledge. Additionally, the patient also had limited clinical symptoms. Our patient displays the importance of checking for cryoglobulins and obtaining a nerve biopsy when the serum is positive. Both of these diagnostic tests were integral for directing appropriate treatment for this patient. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Objective To describe the clinical characteristics, histopathologic features, and outcomes of patients in whom vasculitis developed in association with use of tumor necrosis factor-α (TNF-α) inhibitors. Patients and Methods This is a retrospective review of patients evaluated at Mayo Clinic, Rochester, Minnesota, from January 1, 1998, through March 31, 2011, with a diagnosis of vasculitis induced by anti–TNF-α therapy. Results Of 8 patients with vasculitis associated with anti–TNF-α therapy (mean age, 48.5 years), 6 (75%) were female. Four (50%) had rheumatoid arthritis, 1 (13%) had Crohn disease, and 3 (38%) had ulcerative colitis. Five (63%) were treated with infliximab, 2 (25%) with etanercept, and 1 (13%) with adalimumab. The mean duration of treatment before development of vasculitis was 34.5 months. The skin was the predominant organ affected (5 patients [63%]), with the most common cutaneous lesion being palpable purpura (4 of 5 [80%]). Two organs involved in systemic vasculitis were the peripheral nervous system (4 patients [50%]) and kidney (1 patient [13%]). All cases of vasculitis were histopathologically confirmed. Seven of 8 patients improved with discontinuation of therapy (mean time to resolution, 6.9 months) and adjuvant treatment (all 8 received prednisone; another agent was also used in 7); rechallenge with anti–TNF-α therapy was not attempted in any patient. At last follow-up, no patients had experienced a recurrence of vasculitis after therapy discontinuation. Conclusion Cutaneous small-vessel vasculitis was the most common finding, but systemic vasculitis, including peripheral nerve and renal vasculitis, was also frequently observed. PMID:22795634

    A 24 year old woman with systemic lupus erythematosus (SLE) developed widespread necrotic skin ulceration and gigantism of both breasts during an exacerbation of SLE in the last trimester of her second pregnancy. Over the remainder of the pregnancy the ulceration was only controlled by high dose corticosteroids. After parturition, however, it was possible to reduce the steroid dose without recurrence of the ulceration. Images PMID:1888201

  12. Epidemiology of ANCA associated vasculitis

    Full Text Available ANCA associated vasculitis (AAV comprises three syndromes with systemic vasculitis (Wegener’s granulomatosis (WG, Churg Strauss syndrome (CSS and icroscopic polyangiitis (MPA, which all involve small and medium sized vessels and are associated with antibodies against cytoplasmatic antibodies in neutrophils (ANCA. Polyarteritis nodosa (PAN is included in this review as it also affects medium sized vessels, and has many clinical findings in common with the AAV.Since the recognition of ANCA, increasing data have become available on the epidemiology of these vasculitidis. WG constitutes half of the AAV and its prevalence has increased from 30/million in the late 1980’s in the USA to 160/million in this century in northern Europe. The prevalence for the whole group of primary systemic vasculitides is now 300/million in Sweden. The annual incidence of WG increased from 6.0/million to 14/million during the 1990’s in Tromsø, but it is unknown if this is a true increase or the result of an increased awareness of the diagnosis. For the whole group of AAV, the annual incidence in most more recent studies is relatively constant over time and by geographical location, ranging from 13 to 21/million. Nonetheless there are interesting differences in the prevalence of specific vasculitis between different geographical areas, as well as for sub specificities of ANCA.There seems to be a South-North gradient for WG and PR3-ANCA with high figures reported from northern Europe and southern New Zealand. In European studies WG is 90% PR3-ANCA positive. MPA which is predominantly MPO-ANCA associated are more frequent in the Mediterranean countries and also has an increasing gradient towards east-Asia, as almost all AAV in China and Japan are diagnosed as MPA, predominantly MPO-ANCA positive.There are also some ethnic and gender differences. WG is most prevalent among Caucasians in the USA and in people with European ancestors in Paris and in New Zealand, less

    The localized scleroderma (LS) known as morphea, presents a variety of clinical manifestations that can include systemic involvement. Current classification schemes divide morphea into categories based solely on cutaneous morphology, without reference to systemic disease or autoimmune phenomena. This classification is likely incomplete. Autoimmune phenomena such as vitiligo and Hashimoto thyroiditis associated with LS have been reported in some cases suggesting an autoimmune basis. To our knowledge this is the first case of a morphea forming part of a multiple autoimmune syndrome (MAS) and presenting simultaneously with autoimmune thrombocytopenic purpura and central nervous system vasculitis. We report an uncommon case of a white 53 year old female patient with LS as part of a multiple autoimmune syndrome associated with pneumonitis, autoimmune thrombocytopenic purpura and central nervous system vasculitis presenting a favorable response with thrombopoietin receptor agonists, pulses of methylprednisolone and cyclophosphamide. Is likely that LS have an autoimmune origin and in this case becomes part of MAS, which consist on the presence of three or more well-defined autoimmune diseases in a single patient.

    To guide nosology and classification of patients with eosinophilic granulomatosis with polyangiitis (EGPA) based on phenotype and presence or absence of ANCA. Organ manifestations and ANCA status were retrospectively analyzed based on the presence or not of predefined definite vasculitis features or surrogates of vasculitis in patients asthma, eosinophilia, and at least one systemic organ manifestation attributable to systemic disease. The study population included 157 patients (mean age 49.4±14.1), with a follow-up of 7.4±6.4years. Patients with ANCA (31%) more frequently had weight loss, myalgias, arthralgias, biopsy-proven vasculitis, glomerulonephritis on biopsy, hematuria, leukocytoclastic capillaritis and/or eosinophilic infiltration of arterial wall on biopsy, and other renal disease. A total of 41% of patients had definite vasculitis manifestations (37%) or strong surrogates of vasculitis (4%), of whom only 53% had ANCA. Mononeuritis multiplex was associated with systemic vasculitis (p=0.005) and with the presence of ANCA (p<0.001). Overall, 59% of patients had polyangiitis as defined by definite vasculitis, strong surrogate of vasculitis, mononeuritis multiplex, and/or ANCA with at least one systemic manifestation other than ENT or respiratory. Patients with polyangiitis had more systemic manifestations including arthralgias (p=0.02) and renal disease (p=0.024), had higher peripheral eosinophilia (p=0.027), and a trend towards less myocarditis (p=0.057). Using predefined criteria of vasculitis and surrogates of vasculitis, ANCA alone were found to be insufficient to categorise patients with vasculitis features. We suggest a revised nomenclature and definition for EGPA and a new proposed entity referred to as hypereosinophilic asthma with systemic (non vasculitic) manifestations.

    Kawasaki disease is an acute, systemic vasculitis of unknown etiology. Although gastrointestinal involvement does not belong to the classic diagnostic criteria; diarrhea, abdominal pain, hepatic dysfunction, hydrops of gallbladder, and acute febrile cholestatic jaundice are reported in patients with Kawasaki disease. We describe here two cases presented with fever, and acute jaundice as initial features of Kawasaki disease.

  17. Isolated vasculitis of the CNS

    2000-01-01

    Vasculitis is a rare cause for disease of the CNS. The isolated vasculitis of the CNS is restricted to the CNS whereas other forms of vasculitis affect various organs including the CNS. Headache, encephalopathy, focal deficits and epileptic seizures are the major symptoms suggestive for vasculitis. One major criterion of the isolated vasculitis of the CNS is the lack of evidence for other vasculitis forms or for pathology of other organs. Angiography displays multifocal segmental stenosis of intracranial vessels. MRI demonstrates multiple lesions which in part show enhancement after gadolinium. A definite diagnosis can only be made on the grounds of biopsy from leptomeninges and parenchyma. Therapy consists of corticosteroids and cyclophosphamid. (orig.) [de

    Full Text Available Henoch-Schönlein purpura (HSP is the most common systemic vasculitis in children. Typical presentations of HSP are palpable purpura of the small vessels in the hips and lower limbs, abdominal pain, arthritis, and hematuria. Scrotal involvement manifested by the presence of scrotal pain and swelling during the course of the disease is rarely seen. HSP without systemic involvement with acute scrotum mimicking testicular torsion is even rare in the medical literature. In most cases, patients with this disease achieve complete recovery. Herein, we report an interesting HSP case with skin symptoms but without systemic involvement and then progression to acute scrotum resembling torsion of testis.

    Full Text Available Antineutrophilic cytoplasmic antibody (ANCA associated vasculitis is one of the rare complications of propylthiouracil treatment. Having a variable clinical spectrum, it may be presented with both skin limited vasculitis and life-threatening systemic vasculitis. In this study, we present a case that developed ANCA-positive vasculitis with skin and kidney involvement (hematuria and proteinuria six months after propylthiouracil treatment was initiated for toxic nodular goiter. Proteinuria recovered dramatically subsequent to radioactive iodine treatment following ceasing the drug.

  20. A pragmatic approach to vasculitis in the gastrointestinal tract.

    2017-06-01

    Although vasculitis involving the gastrointestinal tract (GIT) is an uncommon occurrence, occasionally vasculitis can present as haemorrhagic infarction or ischaemia for which a length of bowel is removed. Invariably, the appropriate clinical history is not forthcoming, or vasculitis is not clinically suspected. The purpose of this overview is to provide the practising gastrointestinal (GI) pathologist with a framework to recognise and diagnose vasculitides within the GIT. The classification may be approached by aetiological agent or size of vessel involved; an international consensus group now favours the latter approach. The symptoms that systemic and/or localised vasculitis may cause in the GIT are protean and non-specific. As a result, pathologists examining resection specimens for unexplained haemorrhagic infarction or ischaemia should be aware that vasculitis may be a potential cause. Several well-known systemic vasculitides such as polyarteritis nodosa, microscopic polyangiitis, eosinophilic granulomatosis with polyangiitis or Churg-Strauss syndrome and granulomatosis with polyangiitis or Wegener's granulomatosis can occur in the GIT. The latter three constitute the antineutrophil cytoplasmic antibody-positive vasculitides. In addition, the so-called solitary organ vasculitis (SOV) can occur in the GIT as the harbinger of later onset systemic vasculitis, and be the cause of the GIT symptoms. In addition, SOV can occur incidentally and coexist with GIT disease such as gallstones or polyps, and there may be no manifestations of systemic vasculitis for years, or not at all.

    Propylthiouracil (PTU)-associated vasculitis is a potentially life-threatening disease with a recent increase in the reported cases in the medical literature. This increase may suggest that some earlier cases have been unrecognized or assigned to an alternative nosology category. Although the skin can be the only organ affected by PTU-associated vasculitis, there are many reports with multiple-system involvement. Classically, the symptoms appear under a tetrad of fever, sore throat, arthralgia, and skin lesions. Cutaneous lesions in reported cases of PTU vasculitis have most commonly consisted of retiform acral, purpuric plaques, or nodules. We report a case of perinuclear antineutrophil cytoplasmic antibody-associated vasculitis developed during treatment with PTU for Grave's disease. © The Author(s) 2014.

    Purpuric lesions appear in acral distribution in a variety of conditions and often provide clues to the clinical diagnosis. Purpuric means "hemorrhagic"-that is, the lesions do not blanch from pressure. This review focuses on dermatoses that produce hemorrhagic lesions in acral distribution from the large groups of the vasculitic diseases and their mimics. Cutaneous small vessel vasculitis is confined to the skin, involves mainly postcapillary venules, and has the hallmark manifestation of palpable purpura. Henoch-Schönlein purpura is an immune complex-mediated systemic vasculitis of the small vessels with manifestations from the skin, joints, kidneys, and gastrointestinal system. Only cases where the immune complexes contain immunoglobulin A type are classified as Henoch-Schönlein purpura. Cryoglobulinemic vasculitis is induced by the deposition of cold-precipitated immune complexes in the small vessels. Urticarial vasculitis comprises a spectrum of conditions with the characteristic course of chronic urticaria, with wheals that persist longer than 24 hours, leave hyperpigmentation, and have leukocytoclastic vasculitis on histologic examination. Polyarteritis nodosa is a rare multisystem, segmental necrotizing vasculitis of mainly the medium-sized vessels. Pigmented purpuric dermatoses are chronic benign dermatoses characterized by petechiae, purpura, and increased skin pigmentation. The hallmark of pigmented purpuric dermatoses is their orange-brown, speckled, cayenne pepper-like discoloration. Copyright © 2016 Elsevier Inc. All rights reserved.

    We aimed to identify whether presentations and outcomes in adult patients with isolated small-vessel primary angiitis of the CNS (PACNS) would differ from other patients with large/medium-vessel involvement. In the French PACNS cohort, we compared the characteristics, treatments and outcomes of patients with isolated small-vessel disease (normal CT, MR and/or conventional angiograms, brain biopsy positive for vasculitis) with other patients who had large/medium-vessel involvement (vessel abnormalities on CT, MR or conventional angiograms). A good functional outcome was defined as a modified Rankin scale ⩽2 at last follow-up, regardless of the occurrence of relapse. Among the 102 patients in the cohort, 26 (25%) had isolated small-vessel PACNS, whereas the 76 others demonstrated large/medium-vessel involvement. Patients with isolated small-vessel PACNS had more seizures (P adult patients with isolated small-vessel PACNS presented some distinct disease features and relapsed more often than other PACNS patients who had large/medium-vessel involvement. Functional outcomes and mortality did not differ. © The Author 2016. Published by Oxford University Press on behalf of the British Society for Rheumatology. All rights reserved.

  5. Neutrophil extracellular traps in vasculitis, friend or foe?

    Science.gov (United States)

    Söderberg, Daniel; Segelmark, Mårten

    2018-01-01

    Neutrophil extracellular traps (NETs) can be found at the sites of vascular lesions and in the circulation of patients with active small vessel vasculitis. Neutrophils from vasculitis patients release more NETs in vitro, and NETs have properties that can harm the vasculature both directly and indirectly. There are several ways to interfere with NET formation, which open for new therapeutic options. However, there are several types of NETs and different mechanisms of NET formation, and these might have different effects on inflammation. Here we review recent findings regarding the pathogenesis and therapeutic potentials of NETs in vasculitis. Experimental mouse models support a role for NETs in promoting vascular damage, where histones and mitochondrial DNA appear to be driving forces. Impaired formation of NETs, however, in an SLE-like mouse model leads to more severe disease, suggesting that NETs can be important in limiting inflammation. Studies on drug-induced vasculitis reveal that levamisole can induce NETosis via muscarinic receptors, predisposing for the generation of autoantibodies, including antineutrophil cytoplasmic autoantibodies (ANCA). This supports the notion that NETs can bridge the innate and adaptive immune systems. NETs can participate in the pathogenesis of vasculitis, but in some models there also seem to be protective effects of NETs. This complexity needs further evaluation with experimental models that are as specific as possible for human primary vasculitis.

    Retinal vaculitis is a sight-threatening inflammatory eye condition that involves the retinal vessels. Detection of retinal vasculitis is made clinically, and confirmed with the help of fundus fluorescein angiography. Active vascular disease is characterized by exudates around retinal vessels resulting in white sheathing or cuffing of the affected vessels. In this review, a practical approach to the diagnosis of retinal vasculitis is discussed based on ophthalmoscopic and fundus fluorescein angiographic findings.

    To report a possible case of leukocytoclastic vasculitis associated with clarithromycin therapy. An 83-year-old white woman was prescribed clarithromycin for pneumonia. Six days after her initial presentation, she developed lesions on her palms. Clarithromycin was discontinued at that time. The following day she developed purpuric eccymotic nonblanching lesions that primarily appeared on the lower extremities, buttocks, and abdomen. Colonoscopy revealed generalized erythema and edema of the bowel mucosa. Gastroscopy revealed duodenitis and gastritis, but no bleeding or ulceration. Skin biopsy of the lesions was compatible with leukocytoclastic vasculitis. Renal function was not affected, although hematuria was noted. All symptoms resolved after drug withdrawal and a short course of corticosteroids. Searches were performed on MEDLINE, Embase, International Pharmaceutical Abstracts, and major adverse drug reaction databases to identify reports and articles discussing clarithromycin- and macrolide-induced leukocytoclastic vasculitis. Leukocytoclastic vasculitis is one category of drug hypersensitivity reactions characterized by distinctive patterns of perivascular inflammation. The case described here is consistent with the diagnosis of leukocytoclastic vasculitis, and is similar to the other single published case report associated with clarithromycin. Leukocytoclastic vasculitis induced by clarithromycin is a rare but serious potential adverse effect.

    Vasculitis, by definition, is inflammation of the vasculature. This inflammation can result in either vessel wall destruction causing aneurysm or rupture, or stenosis causing ischaemia or necrosis. This autoimmune response does not always have a clear cause. Vasculitis is a heterogeneous group of disorders that has been categorised not only by primary and secondary causes, but also by the size of the affected vessel. The secondary causes that can trigger vasculitis include infection (particularly hepatitis B and C and haemorrhagic fever);cancer, autoimmune diseases such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and Sjogren's; drugs or allergic reactions. As vasculitis can affect any part of the vasculature, it can result in a wide range of signs and symptoms. However, one of the most common presentations of vasculitis is a rash, due to small vessel vasculitis, which is most common. A vasculitic rash has certain characteristics that are easily identifiable and differentiate it from other rashes. This is a review from a rheumatologist's perspective of how to identify vasculitis skin changes. If cutaneous vasculitis is suspected, this article identifies other areas of skin that can be affected that need identification, in addition to what to screen for in the history and other differential diagnoses to consider. Subsequently, the article addresses the key investigations to request and a brief overview of the treatment principles for primary vasculitis. © 2015 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

    Full Text Available Objective. To test the prevalence of anti-neutrophil cytoplasmic antibodies (ANCA in systemic sclerosis (SSc and to verify a possible association of ANCA with normotensive renal involvement in SSc. Patients and methods: 51 patients affected by SSc, 35 with diffuse scleroderma (dSSc and 16 with limited scleroderma (lSSc, were tested for ANCA by indirect immunofluorescence (IIF on human ethanol and formalin-acetone-fixed granulocytes (before and after DNase treatment, by conventional enzyme linked immuno-sorbent assay (ELISA and by capture-ELISA. Results. Six out of 51 selected SSc patients had ANCA by IIF (11.7% and five presented a perinuclear/nuclear atypical ANCA pattern. In all cases we only found anti-proteinase3 (aPR3 antibodies. All ANCA positive patients had diffuse form of SSc (17.1%, all were anti-Scl70 positive (aScl70, five patients had proteinuria, three had microscopic haematuria. All ANCA positive patients were normotensive with normal renin plasma levels, the mean erythrocyte sedimentation rate (ESR was higher in this group compared to the other SSc patients. Conclusions. Our study shows that aPR3 is not rare in dSSc. According to the clinical and serological findings and to the recent literature, we can hypothesise that when ANCA are found in SSc, an overlapping of scleroderma with systemic necrotizing vasculitis should be suspected.

    A 28-year-old Japanese male without a significant past medical history presented with new-onset generalized clonic seizure and headache. A brain MRI revealed multiple enhanced lesions on both cerebral hemispheres. Laboratory exams showed no evidence of systemic inflammation or auto-immune antibodies such as ANCAs. Despite four courses of high-dose methylprednisolone pulse therapy and five treatments with plasmapheresis, his symptoms worsened and the MRI lesions progressed rapidly. During these treatments, we performed a targeted brain biopsy, that revealed histological findings consistent with a predominant angiitis of parenchymal and subdural small vessels. He was provided with diagnosis of central nervous system vasculitis (CNSV). Subsequent cyclophosphamide pulse therapy enabled a progressive successful improvement of his symptoms. While diagnostic methods for CNSV remain controversial, histological findings are thought to be more useful in obtaining a more definitive diagnosis than findings in image studies, such as MRI and angiography. We suggest that a brain biopsy should be considered during the early period of cases with suspected CNSV and rapid clinical deterioration. We also detected human herpesvirus 7 (HHV-7) using PCR technology in brain biopsy specimens, however the relationship between CNSV and HHV-7 infection is unknow.

    Vasculitis associated with sarcoid granulomas is an uncommon phenomenon. A 72-year-old female presented with an expanding region of circumscribed alopecia and scalp atrophy of 2 months duration. Biopsy showed non-caseating granulomas, dermal thinning, loss of follicles, fibrosis and muscular vessels disrupted by mixed lymphocyte, macrophage and giant-cell infiltrates. Affected vessels had loss and fragmentation of the elastic lamina, fibrous replacement of their walls and luminal stenosis (endarteritis obliterans). Dermal and vascular advential intralymphatic granulomas and lymphangiectases were found by D2-40 expression, suggesting lymphatic obstruction and poor antigen clearance. No evidence of a post-zoster eruption, systemic sarcoidosis or systemic giant-cell arteritis was found. Two years later, prednisone had halted - but not reversed - progression of her alopecia. Review of the literature showed two types of vasculitis associated with sarcoid granulomas: (i) acute, self-limited leukocytoclastic vasculitis and (ii) chronic granulomatous vasculitis (GV). Persistence of non-degradable material or antigen contributes to the pathogenesis of granulomatous inflammation. In this case, lymphatic obstruction probably impeded clearance of nonimmunologic and/or immunologic stimuli permitting and sustaining the development of sarcoid granulomas and sarcoid GV, ultimately causing scarring alopecia and cutaneous atrophy. © 2015 John Wiley & Sons A/S.

    Vasculitis is a rare disease and clinical symptoms are often unspecific. Accurate and early diagnosis is mandatory in order to prevent complications, such as loss of vision or stroke. Imaging techniques can contribute to establishing a definite diagnosis and to evaluate disease activity and the extent of the disease in various vascular regions. Conventional imaging methods, such as computed tomography (CT) and magnetic resonance (MR) angiography, as well as digital subtraction angiography allow the vessel lumen but not the vessel wall to be depicted. However, vasculitis is a disease which primarily affects the vessel wall, therefore conventional imaging modalities often fail to make a definite diagnosis. Recently black-blood high resolution MR in vivo imaging has been used to visualize cervical and intracranial vasculitis. This review article presents imaging protocols for intracranial and cervical black-blood MR imaging and clinical cases with large vessel vasculitis and vasculitis of the central nervous system. Furthermore the current literature, examples of the most common differential diagnoses of cervical and cranial arteriopathy and the potential of other imaging modalities, such as PET/CT and ultrasound will be discussed.

    : Almost invariably associated with chronic HCV infection, cryoglobulinemic vasculitis is a small-vessel vasculitis commonly affecting the skin, kidneys, and peripheral nervous system. Cardiac involvement, possibly due to cardiac microcirculation involvement, is an utterly rare and severe complication. We describe a case of hypertrophic cardiomyopathy secondary to cryoglobulinemic vasculitis. Evaluation with transthoracic cardiac ultrasound and cardiac MRI evidenced severe left ventricular hypertrophy and diffuse hypokinesia, a marked decrease in left ventricular ejection fraction, and a subtle late enhancement of inferior and lateral left ventricular walls. Upon clinical stabilization, the patient received treatment with anti-CD20 monoclonal antibody rituximab. Clinical and radiological follow-up with cardiac ultrasound and cardiac MRI documented a dramatic and sustained clinical improvement, with marked reduction of left ventricular hypertrophy, resolution of late enhancement, recovery of left ventricular contractility and function.

    Full Text Available Cutaneous polyarteritis nodosa (CPAN is a rare form of cutaneous vasculitis that involves small and medium sized arteries of the dermis and subcutaneous tissue without systemic involvement. It presents with tender subcutaneous nodules, digital gangrene, livedo reticularis and subcutaneous ulcerations. The diagnosis is by skin biopsy and characteristic pathologic feature is a leukocytoclastic vasculitis in the small to medium-sized arterioles of the dermis. We report a rare case of benign cutaneous PAN in a 14-year-old girl who presented with history of fever, subcutaneous nodules with cutaneous ulcer and digital gangrene. The skin biopsy showed leukocytoclastic vasculitis with fibrinoid necrosis in the dermal vessels. She received treatment with steroids and lesions resolved completely over a period of month.

    High-resolution MR imaging is an emerging tool for evaluating intracranial artery disease. It has an advantage of defining vessel wall characteristics of intracranial vascular diseases. We investigated high-resolution MR imaging arterial wall characteristics of CNS vasculitis and reversible cerebral vasoconstriction syndrome to determine wall pattern changes during a follow-up period. We retrospectively reviewed 3T-high-resolution MR imaging vessel wall studies performed on 26 patients with a confirmed diagnosis of CNS vasculitis and reversible cerebral vasoconstriction syndrome during a follow-up period. Vessel wall imaging protocol included black-blood contrast-enhanced T1-weighted sequences with fat suppression and a saturation band, and time-of-flight MRA of the circle of Willis. Vessel wall characteristics including enhancement, wall thickening, and lumen narrowing were collected. Thirteen patients with CNS vasculitis and 13 patients with reversible cerebral vasoconstriction syndrome were included. In the CNS vasculitis group, 9 patients showed smooth, concentric wall enhancement and thickening; 3 patients had smooth, eccentric wall enhancement and thickening; and 1 patient was without wall enhancement and thickening. Six of 13 patients had follow-up imaging; 4 patients showed stable smooth, concentric enhancement and thickening; and 2 patients had resoluton of initial imaging findings. In the reversible cerebral vasoconstriction syndrome group, 10 patients showed diffuse, uniform wall thickening with negligible-to-mild enhancement. Nine patients had follow-up imaging, with 8 patients showing complete resolution of the initial findings. Postgadolinium 3T-high-resolution MR imaging appears to be a feasible tool in differentiating vessel wall patterns of CNS vasculitis and reversible cerebral vasoconstriction syndrome changes during a follow-up period. © 2014 by American Journal of Neuroradiology.

    Although the aetiology of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis remains unclear, it is generally believed that environmental factors such as infections contribute to its development of ANCA-associated vasculitis. Prior Epstein-Barr virus (EBV) infection is reported to be a trigger of systemic vasculitis. We herein report three cases of ANCA-associated vasculitis presenting with infectious mononucleosis due to primary EBV infection. The causal link between the two pathologies could not be proved, but primary EBV infection may play a role in the initiation or exacerbation of ANCA-associated vasculitis. Future studies are necessary to determine the interaction between these diseases conditions.

    The infectious causes of cutaneous vasculitis are well known and include streptococcal infections among others. Cases resulting from parasitic infection are less frequent. Scabies, which is currently on the increase, has only been reported in a few isolated cases. Herein, we report two noteworthy cases of profuse scabies complicated by cutaneous vasculitis. Case 1: a 90-year-old woman, residing in a nursing home, was admitted to our dermatology department complaining of pruritus, present for one month, predominantly on the inside of the thighs and on the buttocks, associated with purpuric lesions on the lower limbs. A skin biopsy revealed leukocytoclastic vasculitis. A diagnosis of scabies was based on severe pruritus and hypereosinophilia and was confirmed by microscopic examination of the parasitology sample and the skin biopsy sample. Despite thorough investigation, no other cause of vasculitis could be found. Complete regression of the skin lesions was achieved with scabies treatment only, without any specific treatment for the vasculitis. Case 2: a 74-year-old man, living in a nursing home, was hospitalized for purpuric papules on the lower limbs, present for one month. Physical examination revealed linear patterns in the interdigital spaces associated with scabies evident on dermoscopic examination. The skin biopsy revealed signs of vasculitis. As in our first case, no aetiology of vasculitis was found and a favorable outcome was achieved by means of scabies treatment alone with no specific treatment for vasculitis. Both of our patients presented scabies and vasculitis. In view of the absence of other causes of vasculitis and of the complete regression of lesions due to vasculitis without recurrence achieved with the scabies treatment alone, a diagnosis was made of scabietic vasculitis, probably as a result of cutaneous hypersensitivity reaction to humeral mediators.

    Objective Pregnancy outcomes of patients with vasculitis are unknown, but are of great concern to patients and physicians. Through an online survey, this study assessed pregnancy outcomes among patients with vasculitis. Methods Participants in the Vasculitis Clinical Research Consortium Patient Contact Registry were invited to respond to an anonymous, internet-based survey that included questions about pregnancy outcomes, the timing of pregnancy relative to a diagnosis of vasculitis, and medication use. Results A total of 350 women and 113 men completed the survey. After a diagnosis of vasculitis, 74 pregnancies were reported by women and 18 conceptions were reported by men. The rate of pregnancy loss was higher among women who conceived after a diagnosis of vasculitis compared to those who conceived prior to diagnosis (33.8% versus 22.4%; P = 0.04). Among women, the rate of preterm births increased significantly for pregnancies conceived after a diagnosis of vasculitis relative to those conceived before diagnosis (23.3% versus 11.4%; P = 0.03). Only 18% of women reported worsening of vasculitis during pregnancy, but those who experienced increased vasculitis activity were more likely to deliver preterm. Exposure to cyclophosphamide or prednisone did not appear to impact pregnancy outcomes; however, the number of pregnancies among women taking these medications was small. Among the pregnancies conceived by men with vasculitis, the timing of diagnosis had no significant effect on the rate of pregnancy loss. Conclusion Women who conceived after a diagnosis of vasculitis had a higher rate of pregnancy loss than those who conceived prior to diagnosis. Vasculitis did not worsen during the majority of pregnancies conceived after diagnosis. PMID:23401494

    Vasculitis represents a specific pattern of inflammation of the blood vessel wall that can occur in any organ system of the body. The neutrophil to lymphocyte ratio (NLR) and red blood cell distribution width (RDW) are currently used as markers of inflammation in several diseases. This study analyzed C-reactive protein level (CRP), erythrocyte sedimentation rate (ESR), white blood cell (WBC), NLR, and RDW in patients who had cutaneous vasculitis, or cutaneous vasculitis with systemic involvement, and in healthy controls. A total of 85 individuals were included in our study: 45 with vasculitis and 40 healthy controls. Patients who had complete blood count (CBC) analysis, CRP, and ESR at the time of skin biopsy were included in the study. NLR was calculated from these parameters. NLR, CRP, ESR, and WBC were significantly higher in patients with vasculitis than in healthy controls (p≤0.05), but RDW did not significantly differ between the two groups. This study suggests that blood NLR may be used for predicting vasculitis, especially cutaneous vasculitis with systemic involvement. © 2017 by the Association of Clinical Scientists, Inc.

    Aim Currently, several different instruments are used to measure disease activity and extent in clinical trials of anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis, leading to division among investigative groups and difficulty comparing study results. An exercise comparing six different vasculitis instruments was performed. Methods A total of 10 experienced vasculitis investigators from 5 countries scored 20 cases in the literature of Wegener granulomatosis or microscopic polyangiitis using 6 disease assessment tools: the Birmingham Vasculitis Activity Score (BVAS), The BVAS for Wegener granulomatosis (BVAS/WG), BVAS 2003, a Physician Global Assessment (PGA), the Disease Extent Index (DEI) and the Five Factor Score (FFS). Five cases were rescored by all raters. Results Reliability of the measures was extremely high (intraclass correlations for the six measures all=0.98). Within each instrument, there were no significant differences or outliers among the scores from the 10 investigators. Test/retest reliability was high for each measure: range=0.77 to 0.95. The scores of the five acute activity measures correlated extremely well with one another. Conclusions Currently available tools for measuring disease extent and activity in ANCA-associated vasculitis are highly correlated and reliable. These results provide investigators with confidence to compare different clinical trial data and helps form common ground as international research groups develop new, improved and universally accepted vasculitis disease assessment instruments.

    Full Text Available Antimyeloperoxidase (MPO, perinuclear antineutrophil cytoplasmic antibodies (pANCA, and/or clinically evident vasculitis in patients with scleroderma have been reported only rarely. The clinical significance and prognosis of ANCA-associated vasculitis in systemic sclerosis is uncertain. To report a case and identify the clinical characteristics of scleroderma patients with ANCA-associated vasculitis. Patients with both vasculitis and scleroderma occurring between 1976 to 2006 were identified using an electronic diagnostic index. These diagnoses were confirmed by retrospective review of complete medical records. Clinical features and outcomes recorded included age at vasculitis diagnosis, connective tissue disease (CTD features, type of scleroderma (limited or diffuse; ANCA serology, vasculitic organ system manifestations; and death. Fourteen cases of scleroderma patients with ANCA-associated and/or small vessel vasculitis were identified. The majority (71% were female, with mean age at vasculitis diagnosis 53 years. Seven patients (50% had overlap CTD features, and the majority (79% had limited variant of scleroderma. All of the 10 patients tested were MPO and pANCA positive. Seven patients (50% had glomerulonephritis, 11 (79% pulmonary involvement including 3 with pulmonary-renal syndrome, 6 skin purpura, and 5 mononeuritis multiplex and/or peripheral neuropathy. Six patients (43% died during followup to 2008. The presence of pANCA-associated small vessel vasculitis is a rarely reported complication of scleroderma. It occurs most commonly in women with limited scleroderma and most commonly includes pulmonary and/or renal involvement, including severe organ-threatening manifestations and death. Further studies are needed to clarify the role and clinical impact of ANCA in scleroderma patients with and without vasculitis.

    In this report we describe a patient with a benign glioma treated with surgery and radiation. After a period of stability he developed subacute bacterial endocarditis, and deteriorated neurologically. Computed tomographic scans did not show recurrent tumor. An angiogram showed vasculitis restricted to the previously irradiated area. Secondary to subacute bacterial endocarditis was the presence of high levels of circulating immune complexes. His neurological status was unchanged after antibiotics, but improved after treatment with dexamethasone. We interpret the clinical course as an immune-complex-mediated vasculitis superimposed on a subclinical radiation vasculitis. This case supports the hypothesis that immune mechanisms may be involved in delayed radiation injury to the nervous system.

    The outcome of childhood acute lymphoblastic leukemia has improved because of intensive chemotherapy and supportive care. The frequency of adverse events has also increased, but the data related to acute central nervous system complications during acute lymphoblastic leukemia treatment are sparse. The purpose of this study is to evaluate these complications and to determine their long term outcome. We retrospectively analyzed the hospital reports of 323 children with de novo acute lymphoblastic leukemia from a 13-year period for acute neurological complications. The central nervous system complications of leukemic involvement, peripheral neuropathy, and post-treatment late-onset encephalopathy, and neurocognitive defects were excluded. Twenty-three of 323 children (7.1%) suffered from central nervous system complications during acute lymphoblastic leukemia treatment. The majority of these complications (n = 13/23; 56.5%) developed during the induction period. The complications included posterior reversible encephalopathy (n = 6), fungal abscess (n = 5), cerebrovascular lesions (n = 5), syndrome of inappropriate secretion of antidiuretic hormone (n = 4), and methotrexate encephalopathy (n = 3). Three of these 23 children (13%) died of central nervous system complications, one from an intracranial fungal abscess and the others from intracranial thrombosis. Seven of the survivors (n = 7/20; 35%) became epileptic and three of them had also developed mental and motor retardation. Acute central neurological complications are varied and require an urgent approach for proper diagnosis and treatment. Collaboration among the hematologist, radiologist, neurologist, microbiologist, and neurosurgeon is essential to prevent fatal outcome and serious morbidity. Copyright © 2015 Elsevier Inc.

    Vasculitides are a challenge to the clinician, in terms of both diagnosis and therapy. Multiple classification systems have been implemented and the numerous classification schemes reflect the complexity of establishing a simple classification that could be functional for daily care. Although vasculitis classification has become increasingly elaborated, some areas remain ill defined. Some forms of vasculitis are still difficult to assign to a specific disease entity. Generally accepted operational criteria are available for many vasculitides, but for some entities there are no effective criteria. Moreover, diagnostic criteria for vasculitis with sufficient strength and/or confidence that can be universally accepted are not yet available. The need for diagnostic criteria validated and agreed upon is particularly relevant in the context of cutaneous vasculitis. The project of the SIDeMaST Italian Group of Immunopathology on cutaneous vasculitis is a national prospective observational study designed to develop and validate diagnostic criteria and to improve and validate classification criteria for cutaneous small vessel vasculitis also known as leukocytoclastic vasculitis (CLV). Primary objective of the study will also be that of developing the CUtaneous VAsculitis Severity Index (CUVASI). Secondary objectives of the project will be: 1) definition of the etiological agents that are most frequently associated with CLV; 2) search for possible correlations between causative agent and peculiar clinical and/or histopathological aspects; 3) evaluation of immunofluorescence pattern observed in this specific group of primitive cutaneous vasculitis in order to characterize the diagnostic sensitivity and specificity of this technique; 4) identification of a set of clinical investigations and laboratory tests to be performed for a correct CLV assessment. Actually 15 Italian dermatological clinics are contributing to the project and anticipated recruiting >100 patients with CLV

  14. Thoracic vasculitis presenting as surgical problems.

    2010-01-01

    We present four patients with vasculitis manifesting with unusual clinical or pathological features, generating surgical problems. Two cases presented with pulmonary hypertension, with investigations and radiological evidence prompting clinical suspicion of pulmonary thrombo-embolic disease. First case, with an antecedant history of Wegener\\'s granulomatosis (WG), demonstrated following "embolectomy", WG involving the large pulmonary elastic arteries. The second case of inoperable "pulmonary thrombo-embolic disease" was subsequently found at limited post mortem to have giant cell arteritis, which affected widespread small peripheral pulmonary arterial vessels. The other two cases were of aortitis occurring in the background of immune-mediated disease, which had been treated with aggressive immunosuppression regimens. The first of these was a case of Cogan\\'s syndrome complicated by descending aortitis, a rarely reported phenomenon, with co-existent acute endocarditis of the aortic valve leaflets. Most cases of endocarditis in this context occur secondary to and in continuity with ascending aortitis. That this case, and a case of ascending aortitis occurring in the context of relapsing polychondritis occurred in the face of aggressive immunosuppression with an apparent clinical response, underscores the need to not accept a clinical picture at face value. This has implications for clinical management, particularly in the follow-up of surgical prosthetic devices such as grafts which may be used in these cases. All four cases emphasise the continued importance of histology and the post-mortem examination in elucidating previously undetected or unsuspected disease.

    Eicken, Sibylle; Gugger, Mathias; Marti, Hans-Peter

    2012-05-01

    The various types of glomerulonephritis, including many forms of vasculitis, are responsible for about 15% of cases of end-stage renal disease (ESRD). Arterial hypertension represents a frequent finding in patients suffering from glomerulonephritis or vasculitis and hypertension also serves as an indicator for these severe types of diseases. In addition, there are symptoms and signs like hematuria, proteinuria and renal failure. Especially, rapidly progressive glomerulonephritis (RPGN) constitutes a medical emergency and must not be missed by treating physicians. This disease can either occur limited to the kidneys or in the context of a systemic inflammatory disorder, like a vasculitis. If left untreated, RPGN can lead to a necrotizing destruction of glomeruli causing irreversible kidney damage within several months or even weeks. With respect to the immunologically caused vasculitis, there are - depending upon the severity and type of organ involved - many clinical warning signs to be recognized, such as arterial hypertension, hemoptysis, arthalgias, muscle pain, palpable purpura, hematuria, proteinuria and renal failure. In addition, constitutional signs, such as fever and loss of body weight may occur concurrently. Investigations of glomerulonephritis or vasculitis must contain a careful and complete examination of family history and medications used by the respective patient. Thereafter, a thorough clinical examination must follow, including skin, joints and measurement of arterial blood pressure. In addition, a spectrum of laboratory analyses is required in blood, such as full blood screen, erythrocyte sedimentation rate, CRP, creatinine, urea and glucose, and in urine, including urinalysis looking for hematuria, red cell casts and proteinuria. Importantly, proteinuria needs to be quantified by the utilization of a random urine sample. Proteinuria > 3g/d is diagnostic for a glomerular damage. These basic tests are usually followed by more specialized analyses

  17. Present and future management of anti-neutrophil cytoplasmic antibody associated vasculitis: how therapy changed the prognosis

    Directory of Open Access Journals (Sweden)

    Massimo L’Andolina

    2013-03-01

    Full Text Available Anti-neutrophil cytoplasmic antibody associated vasculitis is part of a multi-systemic idiopathic, small vessel pouci-immune vasculitis. Given the heterogeneous spectrum of the disease, and the need to update therapeutic protocols, the aim of this review was to evaluate clinical-diagnostic approaches. We examined statistical data available in the literature, in particular the 2010 review of St. Hamour et al. Management of Anca-associated Vasculitis, published in Therapeutics and Clinical Risk Management. Acute immunosuppressive therapy and long-term maintenance, with the use of prednisolone, have significantly changed the prognosis of this disease, particularly compared with the 1970s before the introductions of steroids and cyclophosphamide. New drugs such as rituximab, monoclonal antibodies and other modulating immune system molecules are entering clinical use, and experience will confirm whether or not therapeutic guidelines are appropriate. The current diagnostic tools, ranging from laboratory and autoimmune tests, chest X-ray, broncho-alveolar lavage to capillaroscopy, allow prompt diagnosis and early treatment through a first phase of induction-remission, and a second phase of maintenance. There are, however, recurrent and refractory forms of the disease that require long-term immunosuppression and further research into this is merited. These issues have continued to drive the search for safer and more effective modulation of the immune system using targeted immunotherapy. However, the treatment limitations of incomplete efficacy, infection, and cumulative toxicity persist. Modifications to traditional treatment protocols by the use of azathioprine or methotrexate rather than cyclophosphamide, and the introduction of newer agents, such as rituximab, have meant that outcomes have been maintained while toxicity has been reduced.

    Full Text Available The prevalence of cocaine adulterated with levamisole-induced vasculitis is increasing and physicians should be aware of this unique entity. There have been many reports of cutaneous vasculitis syndrome caused by cocaine which is contaminated with levamisole. Levamisole was used as an antihelminth drug and later was rescinded from use in humans due to adverse effects. Through this paper, we will report a 39-year-old crack cocaine user who presented with purpuric rash and skin necrosis of his ear lobes. Levamisole-induced vasculitis syndrome was suspected. A urine toxicology screen was positive for cocaine, opiates, and marijuana. Blood work revealed positive titres of ANA and p-ANCA, as well as anti-cardiolipin antibody. Biopsy taken from the left ear showed focal acute inflammation, chronic inflammation with thrombus formation, and extravasated blood cells. Treatment was primarily supportive with wound care.

  20. What matters for patients with vasculitis?

    Advances in clinical care for patients with vasculitis have improved survival rates and created new challenges related to the ongoing management of chronic disease. Lack of curative therapies, burden of disease, treatment-related side effects, and fear of relapse contribute to patient-perceived reduction in quality of life. Patient-held beliefs about disease and priorities may differ substantially from the beliefs of their health care providers, and research paradigms are shifting to reflect more emphasis on understanding vasculitis from the patient's perspective. Efforts are ongoing to develop disease outcome measures in vasculitis that better represent the patient experience. Health care providers who care for patients with vasculitis should be sensitive to the substantial burdens of disease commonly experienced by patients living with the disease and should strive to provide comprehensive care directed towards the medical and biopsychological needs of these patients.

    Leukocytoclastic vasculitis is typically mediated by deposition of immune complexes and is related to many causes, including medication. To the best of our knowledge, leukocytoclastic vasculitis related to cisplatin has not yet been described in the scientific literature. We report a rare case of leukocytoclastic vasculitis after the first cycle of high-dose cisplatin chemotherapy in a patient with larynx carcinoma. A 48-year-old Caucasian man with larynx carcinoma received a high-dose of cisplatin monochemotherapy (100 mg/m 2 every 21 days), along with 70 Gy of radiotherapy divided into 35 sessions, as a therapeutic schedule. Twelve days after the first chemotherapy administration and after 8 sessions of radiotherapy (total of 16 Gy), the patient presented with acute onset of palpable purpura in the lower limbs. The patient was hospitalized for 10 days, and during this period, he underwent several examinations to rule out infectious, autoimmune, and neoplastic disorders. A skin biopsy showed leukocytoclastic vasculitis with a positive pattern for IgM and C3, as detected through direct immunofluorescence. Twenty-five days after cisplatin administration, the chemotherapy regimen was changed to carboplatin AUC 5, and the episodes of purpura ceased, reinforcing the hypothesis of an adverse reaction to cisplatin. Cisplatin can induce leukocytoclastic vasculitis and clinicians should be aware of this potential effect for better case management and diagnosis.

    Purpose: MR imaging and cerebral angiography were correlated in patients with primary angiitis of the central nervous system (PACNS) to assess the relative roles of these imaging modalities in the diagnosis. Material and Methods: In 9 patients, MR imaging and angiography were compared with regard to the relative involvement of each major vascular territory. Vascular territories assessed were the anterior, middle, and posterior cerebral arteries, and the posterior fossa. Results: All patients had angiographic findings consistent with vasculitis in multiple vascular territories. MR findings ranged from normal to diffusely abnormal. One patient had a completely normal MR investigation. Of 50 territories affected by vasculitis on angiography, 17 (34%) were normal on MR. Conclusion: Relative to cerebral angiography, MR imaging is a poor indicator of the presence or absence of PACNS. Angiography is indicated when clinical suspicion of PACNS is strong, regardless of the findings on MR. (orig.)

    Rocky Mountain spotted fever is a tickborne infection that produces a systemic small-vessel vasculitis; its prognosis is excellent if appropriate treatment is initiated early. Because the advent of effective antirickettsial therapies predates the widespread use of brain magnetic resonance imaging, there are limited data on the effect of untreated Rocky Mountain spotted fever infection on neuroimaging studies. We describe a 7-year-old girl with delayed treatment of Rocky Mountain spotted fever who suffered severe neurological impairment. Serial brain magnetic resonance images revealed a progressive "starry sky appearance," which is proposed to result from the same small vessel vasculitis that causes the characteristic skin rash of this infection. Neurological injury can continue to occur despite specific antirickettsial therapy in Rocky Mountain spotted fever. This child's clinical features raise questions about the optimal management of this infection, particularly the utility of immune modulating therapies in cases of delayed treatment and neurological involvement.

    A literature review utilizing Fepafem, Bireme, LiLacs, Scielo Colombia, Scielo Internacional, former MedLine, Pubmed, and BVS Colombia as well as manual searches in the libraries of major Latin American universities was performed to study vasculitis in Latin America. Since 1945, a total of 752 articles have been published by Latin American authors. However, only a minority are devoted to primary vasculitides, and even fewer have been published in indexed journals. Approximately 126 are in OLD, Medline, Pubmed, Bireme, and Scielo. Most publications are from Mexico, followed by Brazil and Colombia. Systematic studies of the epidemiology of primary idiopathic vasculitis are available for a few countries, i.e. Brazil, Mexico, Colombia, Chile, and Peru. Takayasu arteritis and ANCA-associated vasculitis are the best studied forms of vasculitis in Latin America. Interest and expertise in vasculitis is growing in Latin America, as reflected in the increased number of published articles from this region of the world in the last decade. Racial and environmental factors are possibly responsible for the differential expression of various types of primary vasculitis observed in Latin America. With time, the unique features, epidemiology, and better treatment strategies for idiopathic vasculitides in Latin America will emerge.

    Full Text Available Akihiro Takahashi, Wataru Saito, Yuki Hashimoto, Susumu Ishida Department of Ophthalmology, Hokkaido University Graduate School of Medicine, Sapporo, Japan Purpose: A recent study revealed thickening of the inner retinal layers in acute stage of multiple evanescent white dot syndrome (MEWDS; however, the pathogenesis is still unknown. We report two cases with MEWDS whose funduscopy showed obvious retinal vasculitis. Methods: Case reports. Results: Healthy myopic 16- and 27-year-old women were the cases under study. In both cases, funduscopic examination revealed multiple, faint, small, subretinal white dots at the posterior pole to the midperiphery and macular granularity oculus dexter. Retinal vascular sheathing was also observed at midperiphery. Late-phase fluorescein angiography revealed leakages corresponding to the vascular sheathing. Enhanced depth imaging optical coherence tomography revealed the discontinuity of the ellipsoid zone corresponding to the white dots and increased macular choroidal thickness. One month later, these white dots and retinal sheathing spontaneously resolved in both cases. Three months later, impairments of the outer retinal morphology and the visual acuity were restored. Conclusion: These results suggest that retinal vasculitis possibly plays a role in the pathogenesis of thickened inner retinal layers in acute stage of MEWDS. Keywords: enhanced depth imaging optical coherence tomography, choroidal thickness, inner retinal layer, retinal vascular sheathing

    2015-05-08

    Cryoglobulinemia is a heterogeneous systemic autoimmune disease with a wide variety of causes, symptoms and outcomes, and different etiopathogenic pathways involved in the vasculitic organ damage. The discovery of the hepatitis C virus (HCV) in 1989 changed radically the focus of research of the so-called "essential" cryoglobulinemia. Cryoglobulins can be detected in 25-30% of patients with HCV, overwhelmingly representing mixed cryoglobulins. However, only 10-15% of patients present with cryoglobulinemic vasculitis, with a broad spectrum of symptoms including mild or life-threatening manifestations. Consequently, not all patients can be uniformly treated. The key therapeutic points in HCV+ patients with cryoglobulinemic vasculitis cover different aspects. The first is to treat the underlying cause of cryoglobulinemia whenever possible, hence the use of antiviral therapies must always be considered in these patients. An individualized diagnostic approach to assess the number of organs involved and the severity of organ involvement is also essential in the therapeutic planning. This complex clinical scenario leads to an equally complex therapeutic scenario. There are three main treatment strategies for HCV-associated cryoglobulinemic vasculitis: conventional immunosuppression, antiviral treatment and biological therapies. The most recent studies are suggesting a change from the classical therapeutic approach (monotherapeutic regimens) to combination/sequential regimens, including treatments targeting the virus and those directed against the induced autoimmune disease, with the aim of blocking the various etiopathogenic pathways involved.

    Full Text Available To determine the patterns and outcomes of the pauci-immune vasculitis in the nephrology department at hospital La Conception in Marseille, we conducted a retrospective study including all patients with diagnosis of pauci-immune renal vasculitis between January 1, 2000 and December 31, 2007. Among 33 cases, 25 were diagnosed as Wegener granulomatosis (WG, seven as microscopic polyangitis (MPA and one as Churg-Strauss syndrome (SCS. The median age of the patients was 57.7 years and the sex-ratio (M/F was 1.6. The visceral mani-festations included kidneys (100% of patients, lungs (75%, ENT (52% of WG, and nervous system (57% of MPA. The mean serum creatinine at admission was 3.3 mg/dL. Renal biopsies revealed a pauci-immune crescentic gromerulonephritis in 96% of the cases. Two patients with WG received plasmapheresis and seven patients required emergency hemodialysis. Induction therapy comprised cyclophosphamide IV and corticosteroids, while maintenance therapy included azathioprine for the majority of patients. Eighty four percent of the patients experienced complete remission after induction therapy. During maintenance therapy relapses were more frequent among patients with MPA (28% compared to WG cases (12%. After 35 months of follow-up, eight patients ended on chronic hemodialysis, and five patients died. ANCA associated vasculitis are frequent in our patients. Long-term outcomes are relatively good despite a mortality rate of 15% and 25% of the patients entering dialysis after three years of follow-up.

    Purpose: To describe the spectrum of early CT findings of lupus mesenteric vasculitis (LMV) and to assess the utility of CT in the management of this uncommon entity. Methods: Abdominal CT was performed within 1-4 days (average 2.2 days) of the onset of severe abdominal pain and tenderness in 15 women with systemic lupus erythematosus. Prompt high-dose i.v. corticosteroid in 11 patients after the CT diagnosis of LMV was made. CT was performed after abdominal symptoms subsided. Results: Eleven cases revealed CT features suggestive of LMV including conspicuous prominence of mesentric vessels with palisade pattern or comb-like appearance (CT comb sign) supplying focal or diffuse dilated bowel loops (n=11), ascites with slightly increased peritoneal enhancement (n=11), small bowel wall thickening (n=10) with double halo or target sign (n=8). Follow-up CT before high-dose steroid therapy revealed complete or marked resolution of the abnormal CT findings. Conclusion: CT is helpful for confirming the diagnosis of LMV, especially the comb sign which may be an early sign. Bowel ischemia due to LMV is less ominous than previously expected, and the abnormal CT findings were reversible when early diagnosis and prompt i.v. steroid therapy could be achieved. (orig.)

    Anti-neutrophil cytoplasmic antibodies (ANCA) vasculitides are immune-mediated disorders that primarily affect small blood vessels of the airway and kidneys. Lung involvement, one of the hallmarks of microscopic polyangiitis and granulomatosis with polyangiitis, is associated with increased mortality and morbidity. In recent years, several retrospective series and case reports have described the association of interstitial lung disease (ILD) and ANCA vasculitis, particularly those positive for ANCA specific for myeloperoxidase. In the majority of these patients pulmonary fibrosis occurs concurrently or predates the diagnosis of ANCA vasculitis. More importantly, these studies have shown that ILD has an adverse impact on the long-term prognosis of ANCA vasculitis. This review focuses on the main clinical and radiologic features of pulmonary fibrosis associated with anti-neutrophil cytoplasmic antibodies. Major histopathology features, prognosis and therapeutic options are summarized. Copyright © 2017 Elsevier B.V. All rights reserved.

    Cerebral vasculitis can have a variety of origins. Furthermore, there are no vasculitis-specific symptoms or imaging signs and vasculitis of the CNS can mimic many other neurological diseases, which require different treatment approaches. Thus, the clinical and radiological diagnosis of cerebral vasculitis is challenging. Magnetic resonance imaging (MRI) and MR angiography (MRA) should be the radiological imaging methods of choice to assess the degree of parenchymal damage and to detect vessel wall changes. If the results are unclear digital subtraction angiography (DSA) should be pursued in order to also detect changes in medium sized vessels. Vasculitis of small vessels cannot be detected by vascular imaging and requires brain or leptomeningeal biopsy. In this review we present the current diagnostic approach and a variety of imaging findings in cerebral vasculitis and discuss the main radiological differential diagnoses. (orig.) [German] Die zerebrale Vaskulitis kann viele Ursachen haben. Daher ist die klinische und radiologische Diagnose schwierig, auch weil es etliche vaskulitistypische Symptome und MR-Befunde bei anderen Erkrankungen gibt. Die ZNS-Vaskulitis kann zahlreiche andere neurologische Erkrankungen imitieren, die unterschiedlicher Therapie beduerfen. MRT und MR-Angiographie (MRA) sind die Verfahren der Wahl, mit denen die radiologische Diagnostik begonnen werden sollte, um den Parenchymschaden und den Gefaessbefall zu beurteilen. Bei unklaren Befunden kann eine digitale Subtraktionsangiographie (DSA) ergaenzt werden, um auch mittelgrosse Gefaesse beurteilen zu koennen. Der Befall kleiner Gefaesse kann nur bioptisch nachgewiesen werden. In der folgenden Uebersicht stellen wir das diagnostische Herangehen bei zerebraler Vaskulitis vor, praesentieren zahlreiche Befunde und diskutieren die wichtigsten radiologischen Differenzialdiagnosen.

    The purpose of this study is to describe an association of unilateral multifocal choroiditis (MFC), retinal vasculitis, optic neuropathy, and bilateral keratoconus in a young Saudi male. A 27-year-old male patient with stable bilateral keratoconus presented with a painless vision loss in his left eye. Ophthalmic examinations revealed multiple foci of idiopathic chorioretinitis, retinal vasculitis, and mild optic disc leakage on fluorescein angiography, all of which resolved on systemic therapy with mycophenolate mofetil and prednisone after 3 months. Systemic medication was stopped after 8 months. One year after presentation, patient's visual acuity has improved and remained stable. Systemic immunomodulatory therapy can be effective in managing and leading to resolution of MFC, retinal vasculitis, and optic disc leak in young patients.

  14. An intense and short-lasting burst of neutrophil activation differentiates early acute myocardial infarction from systemic inflammatory syndromes.

    Full Text Available BACKGROUND: Neutrophils are involved in thrombus formation. We investigated whether specific features of neutrophil activation characterize patients with acute coronary syndromes (ACS compared to stable angina and to systemic inflammatory diseases. METHODS AND FINDINGS: The myeloperoxidase (MPO content of circulating neutrophils was determined by flow cytometry in 330 subjects: 69 consecutive patients with acute coronary syndromes (ACS, 69 with chronic stable angina (CSA, 50 with inflammation due to either non-infectious (acute bone fracture, infectious (sepsis or autoimmune diseases (small and large vessel systemic vasculitis, rheumatoid arthritis. Four patients have also been studied before and after sterile acute injury of the myocardium (septal alcoholization. One hundred thirty-eight healthy donors were studied in parallel. Neutrophils with normal MPO content were 96% in controls, >92% in patients undergoing septal alcoholization, 91% in CSA patients, but only 35 and 30% in unstable angina and AMI (STEMI and NSTEMI patients, compared to 80%, 75% and 2% of patients with giant cell arteritis, acute bone fracture and severe sepsis. In addition, in 32/33 STEMI and 9/21 NSTEMI patients respectively, 20% and 12% of neutrophils had complete MPO depletion during the first 4 hours after the onset of symptoms, a feature not observed in any other group of patients. MPO depletion was associated with platelet activation, indicated by P-selectin expression, activation and transactivation of leukocyte β2-integrins and formation of platelet neutrophil and -monocyte aggregates. The injection of activated platelets in mice produced transient, P-selectin dependent, complete MPO depletion in about 50% of neutrophils. CONCLUSIONS: ACS are characterized by intense neutrophil activation, like other systemic inflammatory syndromes. In the very early phase of acute myocardial infarction only a subpopulation of neutrophils is massively activated, possibly via

    This report describes a patient with chronic hepatitis C undergoing therapy with interferon (IFN) alpha who developed bilateral ischemia of his fingers. We present a 43-year-old man with a failed renal transplant and chronic hepatitis C. He was treated with 6 months of IFN therapy with good reduction of his viral load. He presented with 2 days of pain and swelling in the second digits of both hands. Workup for extrahepatic manifestations of hepatitis C was initiated including assessment for vasculitis because of cryoglobulin- and noncryoglobulin-related causes. Extensive assessment with invasive and noninvasive vascular testing was performed. His workup for vasculitis did not reveal any specific reasons for the ischemic changes. Angiography of his fingers showed mild stenotic changes but no evidence of systemic vasculitis. IFN therapy was stopped and over several weeks his symptoms resolved. The ischemic changes were attributed to IFN therapy. The patient in this report is unique because although IFN has been historically reported to cause a variety of vascular syndromes, the reported experience in hepatitis C patients is small. In addition, the likelihood of encountering vasculitis and vasculitis-like syndromes in patients with hepatitis C is significant, and the increasing use of IFN in this population makes drug-induced vascular changes an essential consideration in this subset of patients.

    The term vasculitis encompasses a heterogeneous group of diseases that share the presence of inflammatory infiltrates in the vascular wall. The diagnosis of large-vessel vasculitis is often a challenge because the presenting clinical features are nonspecific in many cases and they are often shared by different types of autoimmune and inflammatory diseases including other systemic vasculitides. Moreover, the pathogenesis of large-vessel vasculitis is not fully understood. Nevertheless, the advent of new imaging techniques has constituted a major breakthrough to establish an early diagnosis and a promising tool to monitor the follow-up of patients with largevessel vasculitis. This is the case of the molecular imaging with the combination of positron emission tomography with computed tomography (PET/CT) using different radiotracers, especially the (18)F-fluordeoxyglucose ((18)F-FDG). In this review we have focused on the contribution of (18)F-FDG PET in the diagnosis of large-vessel vasculitis. Copyright © 2015 Elsevier España, S.L.U. and SEMNIM. All rights reserved.

    Dengue infection is an important arboviral infection in southeast Asia, especially in India. Neurological manifestations of dengue are increasingly recognized. We report an ischemic stroke due to dengue vasculitis in an 8-year-old child. We present a girl with a short febrile illness followed by episodic severe headache, with gradually progressive hemiparesis and visual impairment. Her brain magnetic resonance imaging revealed multiple infarctions in the anterior and posterior circulation. The magnetic resonance angiogram revealed irregular narrowing of bilateral middle cerebral arteries, right anterior cerebral artery, left posterior cerebral, and bilateral vertebral arteries suggestive of vasculitis. Her dengue serology was strongly positive for immunoglobulin M with 68.9 panbio units. The rest of the evaluation for pediatric stroke was unremarkable. She was treated with intravenous followed by oral corticosteroids and recovered totally with resolution of vasculitis on magnetic resonance angiogram over the next 3 months. This child illustrates possible immune-mediated vasculitis caused by dengue infection which is rather a rare presentation in a child who subsequently recovered well. One should consider dengue in childhood strokes in endemic regions. Copyright © 2014 Elsevier Inc. All rights reserved.

    The purpose of this study was to determine the technical capacity and diagnostic accuracy of 3D time-of-flight magnetic resonance angiography (MRA) in suspected cerebral vasculitis in a retrospective analysis of MRA and digital subtraction angiography (DSA) in 14 young patients with clinical and/or radiological suspicion of cerebral vasculitis. A total of nine arteries were evaluated in each patient. Consensus review of DSA by three observers was the reference standard. The sensitivity for detecting a stenosis varied from 62 to 79% for MRA and from 76 to 94% for DSA, depending on the observer. The specificity for detecting a stenosis varied from 83 to 87% for MRA and from 83 to 97% for DSA. Using the criterion ''more than two stenoses in at least two separate vascular distributions'' to consider the examination as being true positive, the false-positive rates for MRA and DSA were comparable. MRA plays a role as the first angiographical examination in the diagnostic work-up of suspected cerebral vasculitis. When more than two stenoses in at least two separate vascular distributions are depicted on MRA, DSA is not expected to add a significant diagnostic contribution in a patient with suspected cerebral vasculitis. DSA remains necessary when MRA is normal or when less than three stenoses are seen. (orig.)

  20. Cerebral vasculitis associated with Schistosoma mansoni infection

    Camuset Guillaume

    2012-09-01

    Full Text Available Abstract Background Cerebral involvement in schistosomiasis is not rare, but it is underdiagnosed because of the lack of clinical suspicion and the frequency of asymptomatic forms. Neurologic complications are generally supported by granuloma formation around ectopic eggs which have migrated to the brain. Moreover, vascular lesions and cerebral arteritis have been well documented in histopathological studies. Nevertheless, cerebral vasculitis in later stages of the Schistosoma mansoni infection have not yet been described in living subjects. Case presentation A 28-year-old french woman had a stroke linked with cerebral vasculitis, 6 monthes after returning from Burkina-Faso. At the same time, a S. mansoni disseminated infection was diagnosed. She suffered from a new stroke after undertaking praziquantel therapy, which lead us to associate the S. mansoni infection and cerebral vasculitis. Conclusion This is the first report of such association, since cerebral vasculitis has never been described in later stages of the S. mansoni infection. Although the causal link between the two pathologies could not be proved, we suggest that S. mansoni is able to cause severe vascular damage in cerebral vessels. Schistosomiasis must be investigated in the event of a brain infarct in young people, particularly in patients originating or returning from an endemic area.

  1. Perspective on future therapy of vasculitis.

    2000-10-01

    This article summarizes recent advances in the management of various vasculitic syndromes and discusses potential new therapies based on a better understanding of their pathogenesis and natural history. Current efforts for optimization of testing for antineutrophil cytoplasmic antibodies and improvement of diagnostic criteria will certainly have a significant impact on future therapy. Biologic agents such as interferon-alpha are already in use in various vasculitides, whereas others, such as inhibitors of tumor necrosis factor-alpha, are in phase I clinical trials. Agents that selectively inhibit distinct steps in the pathogenesis of vasculitis are in preclinical or early clinical stages of development. Newer (mycophenolate mofetil, leflunamide) or older (methotrexate, azathioprine) immunosuppresive agents are finding new roles in the management of vasculitides. For patients with severe vasculitis, short-term use of cytotoxic agents, such as cyclophosphamide, alone or in combination with biologic agents, may expedite remission, which could then be better maintained with other, less toxic (and less expensive) immunosuppressive agents, such as methotrexate, azathioprine, mycophenolate mofetil, and leflunamide. For patients with mild or moderately severe vasculitis, these latter agents alone may be adequate. New therapeutic studies in vasculitis should better address the impact of therapy on health-related quality of life and its long-term toxicity.

    The purpose of this study was to determine the technical capacity and diagnostic accuracy of 3D time-of-flight magnetic resonance angiography (MRA) in suspected cerebral vasculitis in a retrospective analysis of MRA and digital subtraction angiography (DSA) in 14 young patients with clinical and/or radiological suspicion of cerebral vasculitis. A total of nine arteries were evaluated in each patient. Consensus review of DSA by three observers was the reference standard. The sensitivity for detecting a stenosis varied from 62 to 79% for MRA and from 76 to 94% for DSA, depending on the observer. The specificity for detecting a stenosis varied from 83 to 87% for MRA and from 83 to 97% for DSA. Using the criterion ''more than two stenoses in at least two separate vascular distributions'' to consider the examination as being true positive, the false-positive rates for MRA and DSA were comparable. MRA plays a role as the first angiographical examination in the diagnostic work-up of suspected cerebral vasculitis. When more than two stenoses in at least two separate vascular distributions are depicted on MRA, DSA is not expected to add a significant diagnostic contribution in a patient with suspected cerebral vasculitis. DSA remains necessary when MRA is normal or when less than three stenoses are seen. (orig.)

    Dense deposit disease is caused by fluid-phase dysregulation of the alternative complement pathway and frequently deviates from the classic membranoproliferative pattern of injury on light microscopy. Other patterns of injury described for dense deposit disease include mesangioproliferative, acute proliferative/exudative, and crescentic GN. Regardless of the histologic pattern, C3 glomerulopathy, which includes dense deposit disease and C3 GN, is defined by immunofluorescence intensity of C3c two or more orders of magnitude greater than any other immune reactant (on a 0–3 scale). Ultrastructural appearances distinguish dense deposit disease and C3 GN. Focal and segmental necrotizing glomerular lesions with crescents, mimicking a small vessel vasculitis such as ANCA-associated GN, are a very rare manifestation of dense deposit disease. We describe our experience with this unusual histologic presentation and distinct clinical course of dense deposit disease, discuss the pitfalls in diagnosis, examine differential diagnoses, and review the relevant literature.

    Cutaneous vasculitis is common, yet the risk factors for its chronicity have not been established. To describe the clinical spectrum and identify risk factors for chronicity of cutaneous vasculitis. Retrospective data analysis of 275 patients diagnosed with cutaneous vasculitis from January 2008 to December 2013. The mean age was 33.7 (±17.89) years, with female predominance. The majority of patients were Malays (67.3%). Skin biopsy was performed in 110 (40%) patients. The commonest sign was palpable purpura (30.6%). The aetiology remained elusive in 51.3% of patients. Common identifiable causes include infection (19.7%) and connective tissue disease (10.2%). Extracutaneous features were noted in 46.5% of patients. Erythrocyte sedimentation rate and antinuclear antibody were raised in 124 of 170 and 27 of 175 patients with documented results respectively. Cutaneous vasculitis was the presenting symptom in seven patients with newly diagnosed systemic lupus erythematosus. Anti Streptolysin O Titre was positive in 82 of 156 patients with documented results. Despite antibiotics, 31.7% of them had chronic lesions. Prednisolone alone was used in 20% of patients while 16.4% needed steroid-sparing agents. Most patients who needed systemic therapy (62%) had unidentifiable aetiology. Among the 155 patients who remained under follow up, 36.4% had chronic disease, one patient succumbed due to septicaemia, and the rest fully recovered within three months. The presence of ulcerative lesion was significantly associated with developing chronic vasculitis (p=0.003). The clinical spectrum of cutaneous vasculitis in our population was similar to other studies. Ulcerative lesion predicts a chronic outcome.

    Full Text Available BACKGROUND Cutaneous vasculitis is a condition caused by various aetiologies. They can be primary or secondary. Cutaneous lesions maybe a pointer to systemic diseases. So, it is important to identify the various aetiological factors in the occurrence of the various types of cutaneous vasculitis. The patterns and the various aetiologies of cutaneous vasculitis in Kerala is not well documented in the existing literature. MATERIALS AND METHODS The present study is a cross-sectional descriptive study of patients with a clinical diagnosis of cutaneous small vessel vasculitis admitted in Medicine and Dermatology Wards of Calicut, Government Medical College during January 2013 to December 2013. A detailed history and clinical examination of patients along with histopathological examination of skin biopsy was done. RESULTS Out of the 70 cases of cutaneous vasculitis studied, idiopathic cutaneous small vessel vasculitis was the most common type followed by Henoch-Schonlein purpura. The most common aetiology identified was drugs followed by infections. No aetiological factor was identified in 42.8% of the cases. CONCLUSION An aetiological association could be found in 57.8% of cases. The causes identified include drugs, infections, malignancy, connective tissue disorder associated, chronic systemic diseases and Behcet’s disease in decreasing order of frequency.

    A 17-year-old female patient affected by systemic lupus erythematosus (SLE) (who had been taking 300 mg/die of hydroxychloroquine for 3 years), Graves' disease (treated with 10 mg/die of tapazole), and celiac disease came to our attention for urticarial vasculitis. She had been taking prednisone (25 mg/die) for 3 days, and her blood tests showed high levels of Mycoplasma pneumoniae IgM and IgG antibodies. The association between urticaria and M. pneumoniae infections can be present in up to 7% of the cases and, to the best of our knowledge, only two reports of urticarial vasculitis and M. pneumoniae in adults are available in the literature. Urticarial vasculitis can also be a rare cutaneous manifestation of SLE (affecting 2% of the patients), and our case is the first in the literature describing the coexistence of M. pneumoniae infection, SLE, and urticarial vasculitis in a pediatric patient, a case that rises an important differential diagnosis issue about the origin of urticarial vasculitis: SLE reactivation or urticarial vasculitis due to M. pneumoniae infection?

    To understand the clinical spectrum of cocaine-levamisole-induced vasculitis. Worldwide recreational drug consumption is high among the adult population from various social strata. The use of cocaine with levamisole, a frequently added antiparasitic diluent, favors the manifestations of vasculitic lesions, especially in the skin. New insights into immunological mechanisms involved in the pathogenesis of the disease. There are still many unknown aspects in the pathogenesis of this disease, such as the immune system interaction with p-ANCAs and the release of inflammatory NETs (neutrophil extracellular traps), which are the origin of auto-antigens and tissue damage, manifesting as vasculitic purpura on the skin. The clinical presentation constitutes a challenge for the clinician to be able to distinguish it from small-vessel vasculitides. This paper intends to improve the understanding of this condition, exhibiting the broad clinical spectrum of local and systemic manifestations of cocaine-levamisole-induced vasculitis, to facilitate a timely diagnosis, in order to take corrective measures and avoid sequelae, along with tissue damage and the consequent deformities and permanent scars.

    Retinal vasculitis is a sight-threatening inflammatory eye condition that involves the retinal vessels. Detection of retinal vasculitis is made clinically, and is confirmed with the help of fundus fluorescein angiography. Active vascular disease is characterized by exudates around retinal vessels resulting in white sheathing or cuffing of the affected vessels. In this review, a practical approach to the diagnosis of retinal vasculitis is discussed based on ophthalmoscopic and fundus fluorescein angiographic findings.

    Abdominal pain in systemic lupus erythematosus (SLE) patients has rarely been analyzed in pediatric populations. We planned to investigate the potential differences between childhood-onset and adult-onset SLE patients who were hospitalized because of acute abdominal pain. A retrospective study including 23 childhood-onset SLE patients with 38 admissions and 88 adult-onset SLE patients with 108 admissions from 1999 to 2008 were conducted in our hospital. All of them had the chief complaint of diffuse abdominal pain. The etiologies of acute abdominal pain in adult-onset SLE patients were more diverse than childhood-onset SLE patients. The most common cause of acute abdominal pain in SLE patients was lupus mesenteric vasculitis (LMV) (18.5%), followed by acute gastroenteritis (14.4%), pancreatitis (10.3%), appendicitis (7.5%), and cholecystitis (6.2%). Compared with adults, children were admitted more often due to LMV (31.6% versus 13.9%; P = 0.016), had more frequently recurrent episodes (39.1% versus 14.8%; P = 0.009), and were more often treated with immunosuppressive agents (31.6% versus 7.4%; P abdominal pain should be considered in SLE patients. LMV is the most common cause of acute abdomen in childhood-onset SLE patients with low mortality and morbidity provided by prompt diagnosis and timely administration of high-dose intravenous corticosteroids after excluding real surgical abdomen.

    Whereas in the past the term “vasculitis” was most frequently used in context with systemic vasculitides, such as the large vessel vasculitides (LVV) Takayasa arteritis and giant cell arteritis, characterized by inflammation of blood vessel walls, it nowadays comprises also inflammatory changes of the vessel wall as a substantial part of the atherosclerotic disease process. Implementing non-invasive imaging techniques, such as computed tomography angiography (CTA), magnetic resonance angiography (MRA) as well as positron emission tomography (PET) in the diagnostic algorithm of atherosclerosis and LVV, depicts a promising step towards an earlier detection with a, consecutively, improved therapeutic approach and potentially prognostic benefit in patients suffering from vasculitis. Mainly molecular imaging with 18F-fluorodeoxyglucose (FDG) PET seems to be promising in offering an early and sensitive identification of inflammatory changes in both, atherosclerosis and LVV. This review will therefore provide an overview on the diagnostic performance and clinical relevance of FDG-PET in monitoring vasculitis in atherosclerosis and LVV, with a focus on LVV.

    Gastrointestinal involvement in vasculitis may result in life-threatening complications. However, its variable clinical presentations and endoscopic features, and the rarity of the disease, often result in delayed diagnosis. Clinical characteristics, endoscopic features, and histopathological findings were reviewed from medical records. Of 6,477 patients with vasculitis, 148 were diagnosed as primary vasculitis with upper gastrointestinal involvement. Of these, 21 cases (14.2%) were classified as large-vessel vasculitis, 17 cases (11.5%) as medium-vessel vasculitis, and 110 cases (74.3%) as small-vessel vasculitis. According to the specific diagnosis, IgA vasculitis (Henoch-Schönlein purpura) was the most common diagnosis (56.8%), followed by Takayasu arteritis (14.1%), microscopic polyangiitis (10.1%), and polyarteritis nodosa (6.8%). Gastrointestinal symptoms were present in 113 subjects (76.4%), with abdominal pain (78.8%) the most common symptom. Erosion and ulcers were striking endoscopic features, and the second portion of the duodenum was the most frequently involved site. Biopsy specimens were obtained from 124 patients, and only eight (5.4%) presented histopathological signs of vasculitis. Diagnosis of vasculitis involving the upper gastrointestinal tract is difficult. Because of the widespread use of endoscopy, combining clinical features with endoscopic findings may facilitate making appropriate diagnoses; however, the diagnostic yield of endoscopic biopsy is low.

    Background . Renal-limited myeloperoxidase vasculitis with simultaneous rheumatoid arthritis is reported as a rare occurrence. Review of literature suggests that most patients had a diagnosis of rheumatoid arthritis for several years prior to presenting with renal failure from myeloperoxidase vasculitis. Case Presentation . A 58-year-old Caucasian male presented to the hospital experiencing malaise, fevers, decreased oral intake, nausea, and vomiting for one week duration. His past medical history consisted of newly diagnosed but untreated rheumatoid arthritis, hypertension, and non-insulin-dependent diabetes mellitus. He was found to have acute renal failure, proteinuria, and hypoglycemia. Standard therapy, including intravenous fluids, did not improve his acute renal failure. A vasculitis workup resulted in a positive myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA). Renal biopsy revealed crescentic glomerulonephritis (GN) pauci-immune type, suggestive of MPO-ANCA-associated vasculitis (MPO-AAV). Treatment consisted of prednisone, cyclophosphamide, and seven cycles of plasmapheresis, in addition to hemodialysis for uremia. Upon discharge, he received hemodialysis for another week and continued treatment with cyclophosphamide and prednisone. Conclusion . Patients with longstanding rheumatoid arthritis may develop renal failure due to nonsteroidal anti-inflammatory medication use and AA type amyloidosis; however, necrotizing glomerulonephritis with crescent formation has been rarely reported. This stresses the importance of early recognition and swift initiation of treatment.

    During vasculitis, activation of the kinin system induces inflammation, whereby the kinin B1-receptor is expressed and activated after ligand binding. Additionally, activated blood cells release microvesicles into the circulation. Here we determined whether leukocyte-derived microvesicles bear B1-kinin receptors during vasculitis, and if microvesicles transfer functional B1-receptors to recipient cells, thus promoting inflammation. By flow cytometry, plasma from patients with vasculitis were found to contain high levels of leukocyte-derived microvesicles bearing B1-receptors. Importantly, renal biopsies from two patients with vasculitis showed leukocyte-derived microvesicles bearing B1-receptors docking on glomerular endothelial cells providing in vivo relevance. Microvesicles derived from B1-receptor-transfected human embryonic kidney cells transferred B1-receptors to wild-type human embryonic kidney cells, lacking the receptor, and to glomerular endothelial cells. The transferred B1-receptors induced calcium influx after B1-receptor agonist stimulation: a response abrogated by a specific B1-receptor antagonist. Microvesicles derived from neutrophils also transferred B1-receptors to wild-type human embryonic kidney cells and induced calcium influx after stimulation. Thus, we found a novel mechanism by which microvesicles transfer functional receptors and promote kinin-associated inflammation. Copyright © 2016 International Society of Nephrology.

    Cerebral vasculitis, although rare in general, is an important cause of cerebral ischemia, because the treatment strategy is different from that of usual cerebral infarction. On the other hand, a variety of common and uncommon nonvasculitic disorders may mimic vasculitis angiographically or clinically. It is also important to distinguish these vasculitis simulators from true vasculitis in order to avoid the unnecessary and harmful side effects of corticosteroid and immunosuppressant, the mainstay of drug therapy for vasculitis. The diagnosis is often difficult. Angiography is expected to demonstrate the underlying vascular pathology; however, many vasculitides affect small arteries beyond the spatial resolution of conventional angiography. The most important role of the diagnostic imaging is the identification of brain lesions consistent with cerebral vasculitis. Multiple lesions in more than one vascular territory should raise this suspicion, although no specific pattern for this entity exists. In large and medium-sized vessel vasculitis, MRI can directly demonstrate mural thickening and enhancement, which is considered to specific for active inflammation. We propose here a classification for cerebral vasculitis and simulators according to the size of the affected brain vessels, which would help us to make a differential diagnosis. We also review the endovascular techniques for this entity, and its indications. (author)

    Full Text Available Renal paraneoplastic vasculitis (RNPV is rare. It can be revealed by glomerulonephritis, microaneurysms or renal failure. RPNV may precede the onset of the primary tumor, and treatment and prognosis depend on the etiology (primary tumor. A 54-year-old man who had a primary lung adenocarcinoma was admitted for nephrotic syndrome. The investigations revealed RNPV. The patient was treated with corticosteroids at high dose and cyclophosphamide with improvement of the renal condition; however, the patient died from worsening of his pulmonary neoplasia.

  3. Acute and chronic systemic chromium toxicity.

    Although chromium and compounds containing it have been recognized as having potential severe adverse effects on health for more than 160 years, understanding of the systemic toxicology and true hazard of these compounds is still not complete. A review of the current state of knowledge is attempted in this paper, with appropriate attention given to the complications of multiple valence states and solubility. Selected chromium compounds, particularly hexavalent ones, are carcinogens, corrosives, delayed contact sensitizers, and have the kidney as their primary target organ. But chromium is also an essential element for humans. The body clearly possesses some effective detoxification mechanisms for some degree of exposure to hexavalent chrome compounds. The significant features of acute and chronic chromium toxicity are presented in view of these considerations.

    We report the case of a 69-year-old male patient who was admitted for fever, dry cough, recurrent sinusitis with epistaxis, anorexia with weight loss of 20 kg over a 3-month period, myalgia, and mononeuritis multiplex. He was diagnosed with pANCA/anti-MPO associated vasculitis and rectal adenocarcinoma. The tumor was treated by surgical resection. Recurrence of vasculitis occurred during steroid tapering which prompted us to add Mycophenolate mofetyl. A complete remission was achieved. We conclude that in the present case the vasculitis was an independent disease, not a paraneoplastic phenomenon. We discuss the value of different ANCA serologies for diagnostics and follow-up, the epidemiology of vasculitis associated with malignancy, and the concept of vasculitis as a paraneoplastic syndrome.

    To describe the clinical course and successful management of a febrile dog with polyarthritis, splenic vasculitis, thrombosis, and infarction that was infected with Bartonella henselae. An 8-year-old female spayed Labrador Retriever was referred to The Ohio State University Veterinary Medical Center Emergency Service for evaluation of limping, fever, vomiting, and malaise of 4 days' duration. Physical examination abnormalities included generalized weakness, diminished conscious proprioception, bilateral temporalis muscle atrophy, and diarrhea. Peripheral lymph nodes were normal, and there were no signs of abdominal organomegaly, joint effusion, or spinal pain. Abdominal ultrasound identified a nonocclusive splenic vein thrombus. Fine-needle aspirates of the spleen revealed pyogranulomatous inflammation, mild reactive lymphoid hyperplasia, and mild extramedullary hematopoiesis. Splenic histopathology found marked, multifocal to coalescing acute coagulation necrosis (splenic infarctions) and fibrinoid necrotizing vasculitis. Bartonella henselae DNA was amplified by polymerase chain reaction and sequenced from the splenic tissue. The dog responded favorably to antimicrobials and was healthy at the time of follow-up evaluation. Bartonella henselae is an incompletely characterized emerging canine pathogen. This case report establishes a potential role for this bacterium as a cause of vasculitis and thromboembolism, which have not been previously reported in association with B. henselae infection in dogs. © Veterinary Emergency and Critical Care Society 2015.

    Central nervous system vasculitis has multiple presentations, including stroke, seizures, cranial nerve palsies, and encephalopathy. We present the case of an unresponsive 45-year-old woman with vasculitis associated with fulminant intracranial vessel dissection and occlusion with ischemic strokes and subarachnoid hemorrhage secondary to aneurysm rupture. Imaging studies demonstrated both ischemic and hemorrhagic strokes. She had a ruptured right internal carotid artery dorsal variant aneurysm, right vertebral artery dissection with occlusion and posterior inferior cerebellar artery infarct, left vertebral artery dissection, and severe vasculitis involving intracranial and extracranial vessels. She initially was treated for her vasculitis with high-dose steroids followed by clip wrapping of the dorsal variant aneurysm. Unfortunately, her surgery was complicated by intraprocedural rupture, and the patient died during her hospitalization. Fulminant central nervous system vasculitis can occur with critical vascular anomalies that require emergent intervention and should be part of the differential diagnosis of patients presenting with these multiple vascular pathologies.

    Alternative C activation is involved in the pathogenesis of ANCA-associated vasculitis. However, glucocorticoids used as treatment contribute to the morbidity and mortality of vasculitis. We determined whether avacopan (CCX168), an orally administered, selective C5a receptor inhibitor, could replace oral glucocorticoids without compromising efficacy. In this randomized, placebo-controlled trial, adults with newly diagnosed or relapsing vasculitis received placebo plus prednisone starting at 60 mg daily (control group), avacopan (30 mg, twice daily) plus reduced-dose prednisone (20 mg daily), or avacopan (30 mg, twice daily) without prednisone. All patients received cyclophosphamide or rituximab. The primary efficacy measure was the proportion of patients achieving a ≥50% reduction in Birmingham Vasculitis Activity Score by week 12 and no worsening in any body system. We enrolled 67 patients, 23 in the control and 22 in each of the avacopan groups. Clinical response at week 12 was achieved in 14 of 20 (70.0%) control patients, 19 of 22 (86.4%) patients in the avacopan plus reduced-dose prednisone group (difference from control 16.4%; two-sided 90% confidence limit, -4.3% to 37.1%; P =0.002 for noninferiority), and 17 of 21 (81.0%) patients in the avacopan without prednisone group (difference from control 11.0%; two-sided 90% confidence limit, -11.0% to 32.9%; P =0.01 for noninferiority). Adverse events occurred in 21 of 23 (91%) control patients, 19 of 22 (86%) patients in the avacopan plus reduced-dose prednisone group, and 21 of 22 (96%) patients in the avacopan without prednisone group. In conclusion, C5a receptor inhibition with avacopan was effective in replacing high-dose glucocorticoids in treating vasculitis. Copyright © 2017 by the American Society of Nephrology.

    The association of sensorineural hearing loss and vertigo with inflammatory eye disease, usually interstitial keratitis, has been called Cogan's syndrome. The pathogenesis of Cogan's syndrome is unknown, but it has been assumed to be an immune mediated disorder with vasculitis. The histopathology of the inner ear in Cogan's syndrome has been described in 6 case reports. Although common pathologic findings in these reports include degeneration of the auditory and vestibular neuroepithelium, endolymphatic hydrops, fibrosis, and new bone formation, direct pathologic evidence of a vasculitis has not been published. A possible reason for this failure to identify vasculitis was a substantial delay (range, 4-40 years) between the onset of symptoms and examination of the otopathology. In the current case report, the patient had both auditory and vestibular symptoms and interstitial keratitis with a time delay of only 2 to 4 weeks between symptoms and death. Evidence of a vasculitis as a possible underlying etiology included H&E histopathology and anti-CD45 immunostaining of vessels both in the auditory and vestibular systems, supporting the hypothesis of a vasculitis as a mechanism in this disorder. © The Author(s) 2015.

    The primary purpose of this article is to document whether demographic, clinical, regimen-related, intrapersonal, and interpersonal factors predict medication non-adherence for vasculitis patients. A secondary purpose is to explore whether adherence varies by medication type and whether patients experienced drug-related side effects. Vasculitis patients (n=228) completed online baseline and 3-month follow-up surveys. Demographic (age, gender, education, race, marital status, and insurance status), clinical (perceived vasculitis severity, disease duration, vasculitis type, and relapse/remission status), regimen-related (experience of side effects), intrapersonal (depressive symptoms), and interpersonal (adherence-related support from family and friends) factors were measured at baseline. Medication non-adherence was assessed at follow-up using the Vasculitis Self-Management Survey medication adherence sub-scale (α=0.89). Variables that significantly correlated (pvasculitis medication types, patients who experienced side effects were less adherent than patients who did not experience side effects. Multiple factors are associated with medication non-adherence for vasculitis patients. Providers should discuss medication adherence and drug-related side effects with vasculitis patients. Providers may want to particularly target younger patients and patients with clinical signs of depression. PMID:23314654

    Abstract Cutaneous vasculitis may be associated with malignancies, and may behave as a paraneoplastic syndrome. This association has been reported in a variable proportion of patients depending on population selection. We conducted the current study to assess the frequency, clinical features, treatment, and outcome of paraneoplastic vasculitis in a large unselected series of 766 patients with cutaneous vasculitis diagnosed at a single university hospital. Sixteen patients (10 men and 6 women; mean age ± standard deviation, 67.94 ± 14.20 yr; range, 40–85 yr) presenting with cutaneous vasculitis were ultimately diagnosed as having an underlying malignancy. They constituted 3.80% of the 421 adult patients. There were 9 hematologic and 7 solid underlying malignancies. Skin lesions were the initial clinical presentation in all of them, and the median interval from the onset of cutaneous vasculitis to the diagnosis of the malignancy was 17 days (range, 8–50 d). The most frequent skin lesions were palpable purpura (15 patients). Other clinical manifestations included constitutional syndrome (10 patients) and arthralgia and/or arthritis (4 cases). Hematologic cytopenias (11 cases) as well as immature peripheral blood cells (6 cases) were frequently observed in the full blood cell count, especially in those with vasculitis associated with hematologic malignancies. Specific treatment for vasculitis was prescribed in 10 patients; nonsteroidal antiinflammatory drugs (4 patients), corticosteroids (3 patients), chloroquine (1 patient), antihistamines (1 patient), and cyclophosphamide (1 patient). Ten patients died due to the malignancy and 6 patients recovered following malignancy therapy. Patients with paraneoplastic vasculitis were older, more frequently had constitutional syndrome, and less frequently had organ damage due to the vasculitis than the remaining patients with cutaneous vasculitis. In summary, cutaneous paraneoplastic vasculitis is an entity not uncommonly

    émico.Visceral involvement in systemic lupus erythematosus (SLE extends beyond renal and cutaneous management. Pleuro-pulmonary lesions have been recognised and diffuse alveolar damage and hemorrhage are the most difficult patterns to control. Pulmonary compromise in clinical evolution of SLE differs from children to adults, both in morphological patterns and in clinical presentation, depending on immunocompetence and the treatment prescribed. A 16-year-old boy presented asthenia, malaise and bilateral cervical painless adenopathies understood as EBV infection as serological EBV IgG, IgM and EBNA were positive. The symptoms persisted for eight months when discrete erythematous and desquamative nasal and malar rash expressed together with persistent fever, dispnoea and bibasilar crackles. Lymph node and pulmonary biopsises were performed. Lymph node presented follicular hyperplasia and LMP1 (EBV immunostaining was negative. In lung biopsy bronchovascular lesions were consistent with vasculitis and bronchiolitis due to intense macrophage infiltration, validated with CD68 antibody and intra-alveolar macrophages were also present with septal compromise; LMP1 (EBV positive cells were not visualized. The lung pattern seen in CAT as diffuse micronodules all over the lung parenchyme resolved after corticosteroid therapy. The diagnosis of SLE was confirmed by ANA, anti-dsDNA, anti-nDNA and anti-histones positivity. To the best of our knowledge this is the first reported case of pulmonary SLE involvement with vasculitis and diffuse panbronchiolitis - like pattern as the first clinical sign of the disease.

    Lymphocytic vasculitis of the central nervous system is an uncommon subtype of primary angiitis of the central nervous system (PACNS) – a rare inflammatory disorder affecting parenchymal and leptomeningeal arteries and veins. Establishing diagnosis on the basis of neuroimaging only is difficult, as it can mimic a brain tumor. Thus, histological diagnosis is essential for appropriate management. We present a case of biopsy-proven lymphocytic vasculitis mimicking a brain tumor on neuroimaging that was subsequently successfully treated with steroid therapy. We also discuss the findings in perfusion MR (PWI) and MR spectroscopy (MRS). Regional hypoperfusion on PWI and elevation of glutamate and glutamine levels on MRS (without associated typical tumor spectra) are common findings in inflammatory disorders, including PACNS, and can be useful in differential diagnosis with tumors

This vasculitic syndrome affects medium and small-sized vessels, the lung being the most commonly affected organ, followed by the skin. The authors report a case of a 59-year-old male with a past history of asthma and allergic rhinitis. He presented necrohemorragic lesions in the distal phalanx of the 2nd, 3rd and 4th fingers of the lefthand and petechial lesions in the plant of both feet, accompanied by asthenia, anorexia and weight loss. The analytical study revealed leukocytosis with eosinophilia, elevated inflammatory parameters and p-ANCA positive antibodies. The diagnosis of CSS was established based on clinical and histopathological data. Cutaneous manifestations of hemorragic vasculitis are rare in CSS syndrome but can be the first manifestation of the disease. The recognition of this presentation is important for the early diagnosis and treatment of this syndrome.

Cardiovascular complications are thought to be rare in IM. There are very few case reports of EBV-associated vasculitides, like Kawasaki disease and systemic polyarteritis nodosa, however, involvement of the large caliber arteries like the aorta and its branches have been reported only scarcely. Myocarditis also is rare as an early manifestation of EBV infection. We present here a rare case of IM, presented initially with acute myocarditis and later with large-vessels arteritis.

  13. Ultraviolet erythema as an indicator of nonspecific reactivity during hemorrhagic vasculitis in children

    Energy Technology Data Exchange (ETDEWEB)

    Kharitonova, A V

    1973-01-01

    From 1955 to 1967 studies were carried out on 407 children suffering from hemorrhagic vasculitis. For patients in the severe stage of hemorrhagic vasculitis it is characteristic that there are functional shifts in the central nervous system, which are manifested by a changed sensitivity of the skin to ultraviolet irradiation. The appearance of slowed, inert or paradoxal reactions indicates the predominance of processes in the brain that slow down and decrease the reactivity of the organism. In rheumatoid and abdominal-rheumatoid syndromes of the disease, disturbances in indices to skin light-sensitivity are the most manifest. During the recovery period, the indices of ultraviolet erythema, on approaching normal values, still remain low. This behavior requires extensive outpatient observation and treatment of sick children to avoid recidivism. 9 references. (SJR)

    Turner, Ryan B; Haynes, Harley A; Granter, Scott R; Miller, Danielle M

    2009-06-01

    Cutis laxa (CL) is an inherited or acquired connective tissue disorder characterized clinically by loosely hanging skin folds. There is often preceding cutaneous inflammatory eruption (ie, urticaria, eczema, erythema multiforme), and there is frequently internal organ involvement of the gastrointestinal, urogenital, pulmonary, and cardiovascular systems. Histologically, there are degenerative changes in the dermal elastic fibers. Of the few reports on this rare disorder, authors have speculated about an immune-mediated destruction of elastic fibers, and monoclonal gammopathies, such as multiple myeloma or heavy chain deposition disease, have a recognized association with CL. We report an unusual case of rapidly progressing acquired CL associated with leukocytoclastic vasculitis, IgA myeloma, and an immune complex-mediated glomerulonephritis. Light microscopy of the lax skin revealed complete absence of elastic fibers in areas of vasculitis.

    Several types of vasculitis have been observed and reported in temporal association with the administration of various vaccines. A systematic review of current evidence is lacking. This systematic literature review aimed to assess available evidence and current reporting practice of vasculitides as adverse events following immunization (AEFI). We reviewed the literature from 1st January 1994 to 30th June 2014. This review comprises randomized controlled trials, observational studies, case series, case reports, reviews and comments regardless of vaccine and target population. The initial search resulted in the identification of 6656 articles. Of these, 157 articles were assessed for eligibility and 75 studies were considered for analysis, including 6 retrospective/observational studies, 2 randomized controlled trials, 7 reviews, 11 case series, 46 case reports and 3 comments. Most of the larger, higher quality studies found no causal association between vaccination and subsequent development of vasculitis, including several studies on Kawasaki disease and Henoch-Schönlein purpura (IgA vasculitis). Smaller case series reported a few cases of vasculitis following BCG and vaccines against influenza and hepatitis. Only 24% of the articles reported using a case definition of vasculitis. Existing literature does not allow establishing a causative link between vaccination and vasculitides. Further investigations were strengthened by the use of standardized case definitions and methods for data collection, analysis and presentation to improve data comparability and interpretation of vasculitis cases following immunization.

    2013-08-01

    To study the clinical and pathological features of cases of apparent solar purpura, with attention to the recently described phenomenon of inflammatory changes within otherwise typical lesions. We studied 95 cases diagnosed as solar purpura and identified 10 cases (10.5%) in which significant neutrophilic inflammation was present, potentially simulating a leukocytoclastic vasculitis or neutrophilic dermatosis. An additional three cases were identified in subsequent routine practice. The clinical features, including follow-up for subsequent development of vasculitis and histological features were studied. In all cases the histological features were typical of solar purpura, with the exception of inflammatory changes, typically associated with clefting of elastotic stroma. Clinical follow-up information was available for all patients and none developed subsequent evidence of a cutaneous or systemic vasculitis or neutrophilic dermatosis. Inflammatory changes appear to be more frequent in solar purpura than is generally recognised. Awareness of this histological variation and correlation with the clinical findings and evolution is important in avoiding misdiagnosis.

    The purpose of this study was to evaluate the safety and effectiveness of percutaneous transluminal angioplasty for occlusive arterial disease associated with vasculitis. Eleven patients(10 women, 1 man; ages 35-82 years) with the diagnosis of vasculitis of the large vessels underwent interventional treatment during intraarterial angiography. The causes included giant cell arteritis(n = 8) and Takayasu arteritis (n = 3).Thirty-three occlusive lesions (including brachiocephalic and renalarteries, and arteries of upper and lower extremities) were treated with balloon angioplasty and/or stent placement. Follow-up included clinical examination, angiography, and color duplex ultrasound.Technical success was 100% (25/25) for stenoses and 50% (4/8) for occlusive lesions, representing all lesions combined from different anatomic locations. Dissection (n = 3) and arterial rupture with retroperitoneal hematoma (n = 1) was found in three patients. During follow-up (mean 12 months), restenoses(n = 8) and re-restenoses (n = 1)occurred in 8 vascular areas. Three of these lesions were treated with repeated PTA (n = 4). The cumulative primary clinical success rate was 67.6%, cumulative secondary success rate 74.4%, and cumulative tertiary success rate 75.9%. Interventional therapy in systemic vasculitis provides promising results in technical success rates and followup. Angioplasty may result in arterial injury, but the rate of complications is low

  18. Progressive outer retinal necrosis associated with occlusive vasculitis in acquired immunodeficiency syndrome

    Full Text Available A 45-year-old man, a case of acquired immunodeficiency syndrome, received a highly active antiretroviral therapy at the outpatient service for 4 years without regular follow-up. He experienced progressively blurred vision for 6 months and a cutaneous zoster on his back 3 months ago. He was diagnosed with progressive outer retinal necrosis by polymerase chain reaction-restriction fragment length polymorphism using an aqueous humor sample, which revealed an existence of varicella zoster virus. He was given a combination of systemic, intravitreal antiviral and a highly active antiretroviral therapy. Occlusive vasculitis, an unusual finding for progressive outer retinal necrosis, developed in both eyes 1 week after the secondary intravitreal injection. Unfortunately, his vision deteriorated to no light perception in both eyes within 2 weeks. Progressive outer retinal necrosis is characterized clinically as showing minimal or no inflammation in the aqueous and vitreous humors, absence of retinal vasculitis, and patches of yellowish spots located deep in the retina. Physicians should pay attention to this rare case of progressive outer retinal necrosis associated occlusive vasculitis with very poor prognosis in spite of aggressive treatment.

    BACKGROUND Antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis is a severe condition encompassing two major syndromes: granulomatosis with polyangiitis (formerly known as Wegener’s granulomatosis) and microscopic polyangiitis. Its cause is unknown, and there is debate about whether it is a single disease entity and what role ANCA plays in its pathogenesis. We investigated its genetic basis. METHODS A genomewide association study was performed in a discovery cohort of 1233 U.K. patients with ANCA-associated vasculitis and 5884 controls and was replicated in 1454 Northern European case patients and 1666 controls. Quality control, population stratification, and statistical analyses were performed according to standard criteria. RESULTS We found both major-histocompatibility-complex (MHC) and non-MHC associations with ANCA-associated vasculitis and also that granulomatosis with polyangiitis and microscopic polyangiitis were genetically distinct. The strongest genetic associations were with the antigenic specificity of ANCA, not with the clinical syndrome. Anti–proteinase 3 ANCA was associated with HLA-DP and the genes encoding α1-antitrypsin (SERPINA1) and proteinase 3 (PRTN3) (P = 6.2×10−89, P = 5.6×10−12, and P = 2.6×10−7, respectively). Anti–myeloperoxidase ANCA was associated with HLA-DQ (P = 2.1×10−8). CONCLUSIONS This study confirms that the pathogenesis of ANCA-associated vasculitis has a genetic component, shows genetic distinctions between granulomatosis with polyangiitis and microscopic polyangiitis that are associated with ANCA specificity, and suggests that the response against the autoantigen proteinase 3 is a central pathogenic feature of proteinase 3 ANCA–associated vasculitis. These data provide preliminary support for the concept that proteinase 3 ANCA–associated vasculitis and myeloperoxidase ANCA–associated vasculitis are distinct autoimmune syndromes.

    Cryofibrinogenemia is frequently associated with cryoglobulinemia. The aim of this study was to determine the characteristics associated with the presence of cryofibrinogenemia in patients with cryoglobulinemic vasculitis. This was a single-center retrospective study that included patients with cryoglobulinemic vasculitis who were tested for cryofibrinogen at a tertiary referral center between January 1, 2011 and December 31, 2012. Twenty-nine patients fulfilled the CryoVas (cryoglobulinemic vasculitis) Survey criteria for cryoglobulinemic vasculitis. Eighteen patients had a detectable cryofibrinogen (CF-positive) and 11 had no detectable cryofibrinogen (CF-negative). Median cryoglobulin levels were 89 ± 129 mg/L in the CF-positive group and 68 ± 82 mg/L in the CF-negative group (P = .32). Median cryofibrinogen level was 70 ± 174 mg/L. Clinical manifestations were similar in both groups. Cancers and hematological disorders were more frequent among CF-positive patients (39% vs 0%, P = .026). Levels of alpha-1 and alpha-2 globulinemia were higher in the CF-positive group. Cryofibrinogenemia ≥ 100 mg/L was associated with cryoglobulinemic vasculitis (odds ratio [OR] 2.86; 95% confidence interval [CI], 1.06-7.73) in cryoglobulinemic patients. Presence of cryofibrinogenemia was associated with use of corticosteroids, immunosuppressants, or plasmapheresis in cryoglobulinemic vasculitis patients (OR 22.7; 95% CI, 2.02-256.44). Our results strongly suggest that presence of cryofibrinogenemia is associated with a more severe phenotype among patients with cryoglobulinemic vasculitis. Copyright © 2015 Elsevier Inc.

    Full Text Available Purpose: To report on the clinical features and etiology of patients with retinal vasculitis (RV. Materials and Methods: We reviewed medical records of 47 patients (75 affected eyes diagnosed with RV. Clinical presentations, ocular complications, associated systemic diseases, and treatment regimens were registered. Results: Etiology of RV included infectious causes in 10/47, (21% while an association with systemic and/or ocular non-infectious disorders was noted in 22/47 (47%. Eales′ disease and Behcet′s disease represented the most common clinical entities in non-infectious group while tuberculosis-associated RV was diagnosed in 6/10 (60% among those with infectious disorders. RV was bilateral in 28/47 (60% patients. Retinal veins were most commonly affected (72%, 34/47. Involvement of arteries was present in 12/47 (25% and was associated with viral infections and Behcet′s disease. Ocular complications developed in 60/75 (80% eyes. The most common complications were elevated intraocular pressure and/or glaucoma (33/75, 44%. Retinal detachment, vitreous hemorrhage, and cystoid macular edema developed in similar percentages (15%. Conclusions: RV in Thailand manifested mostly in male patients, was typically bilateral and involved mostly veins. Involvement of arteries was observed in patients with viral infections and Behcet′s disease. Tuberculosis was the most common infectious cause.

    period of 16 years were reviewed in a retrospective way. All patients selected fulfilled diagnostic criteria of small vessel vasculitis. The data were extracted and the analysis of survival was completed by phone. Later a bibliographical search was carried out and the results were compared. Thirteen patients with Wegener's granulomatosis, 6 with Churg-Strauss syndrome and 10 with microscopic polyangiitis were included. Fifty five percent (16 were under 55 years old when diagnosis was made and male/female ratio was 2.6 to 1. The diagnostic delay was over a year in 46% of the cases. Respiratory and ear-nose-throat were the most frequently affected systems. Anti-neutrophil cytoplasmic antibodies were present in 79% of patients. Overall mortality was 24% (7/29. There were several differences between the results of our series and the literature: the presentation form, affected systems and percentage of patients with anti-neutrophil cytoplasmic antibodies. Greater diagnostic delay and worse prognosis were observed in anti-neutrophil cytoplasmic antibody negative patients. Special attention should be given to these antibodies since they constitute a significant tool at the time of diagnosis.

    2017-07-01

    The vasculitis can be the consequence of malignancy: most often hematologic rather than solid tumors. The association between large vessels vasculitis and myelodysplastic syndrome is rare. A 55-year-old man experienced asthenia, fever, polyarthritis and inflammatory syndrome. Haematological investigations found a type 2 refractory anemia with excess blasts (RAEB-2) with discovery of severe anemia (Hb: 7,8g/dl) and thrombopenia (platelets: 40,000/mm 3 ). Radiological examinations found thoracic aortitis and carotid vasculitis. Treatment in the form of steroids and azacitidine was instituted. The lack of control of both RAEB-2 and vasculitis was responsible for the death of the patient. Myelodysplastic syndrome and large vessels vasculitis is a rare but serious association disease. The lack of efficiency of corticosteroids seems to be common. Prognosis depends on the haematological treatment effectiveness.

    Full Text Available Urticaria is common in children. Urticarial vasculitis (UV is a potentially more serious, rare variant. The youngest reported case was 12 months of age. A systemically well, 19-month-old girl presented with her mother who was concerned about the development of a rash. On presentation, the child had normal vital signs, was alert, and was well and playing with toys. There was a widespread urticarial rash (raised, pruritic, and erythematous that was most apparent on the trunk with minimal rash on the legs. Overlying this urticarial rash in a similar distribution was a blotchy, palpable purpuric rash and associated hyperpigmentation. Investigations revealed a normal level of haemoglobin, white cells, platelets, and electrolytes. Renal function, international normalised ratio, and activated partial thromboplastin time were all normal. There was no blood or protein in the urine. The erythrocyte sedimentation rate was mildly elevated at 19 mm/hour. Complement results (including C1q obtained later were normal. This case is striking not only because of the rarity of UV in children but also due to the unique diagnostic and prognostic challenges that it raises.

    2013-10-01

    AVN is caused by a disease, or severe trauma that affects the blood supply to the bone or in many cases may be idiopathic, with no known cause. AVN pathophysiology is most closely linked to SLE literature, and there is a strong cause and effect relationship between corticosteroid intake and AVN development in SLE patients, and AVN is extremely rare in the absence of steroid use. Apart from few anecdotal reports, there is no data on exact pathophysiologic mechanisms responsible for AVN in the setting of vasculitis. We saw a 69-year-old man with femoral AVN and a possibility of vasculitis as the underlying cause was raised by the radiologist, and hence we present this literature search on vasculitis per se causing AVN of the bone.

    A specific biomarker that can separate active renal vasculitis from other causes of renal dysfunction is lacking, with a kidney biopsy often being required. Soluble CD163 (sCD163), shed by monocytes and macrophages, has been reported as a potential biomarker in diseases associated with excessive macrophage activation. Thus, we hypothesized that urinary sCD163 shed by crescent macrophages correlates with active glomerular inflammation. We detected sCD163 in rat urine early in the disease course of experimental vasculitis. Moreover, microdissected glomeruli from patients with small vessel vasculitis (SVV) had markedly higher levels of CD163 mRNA than did those from patients with lupus nephritis, diabetic nephropathy, or nephrotic syndrome. Both glomeruli and interstitium of patients with SVV strongly expressed CD163 protein. In 479 individuals, including patients with SVV, disease controls, and healthy controls, serum levels of sCD163 did not differ between the groups. However, in an inception cohort, including 177 patients with SVV, patients with active renal vasculitis had markedly higher urinary sCD163 levels than did patients in remission, disease controls, or healthy controls. Analyses in both internal and external validation cohorts confirmed these results. Setting a derived optimum cutoff for urinary sCD163 of 0.3 ng/mmol creatinine for detection of active renal vasculitis resulted in a sensitivity of 83%, specificity of 96%, and a positive likelihood ratio of 20.8. These data indicate that urinary sCD163 level associates very tightly with active renal vasculitis, and assessing this level may be a noninvasive method for diagnosing renal flare in the setting of a known diagnosis of SVV.

    2013-01-01

    Vasculitis is a clinicopathological entity characterized by inflammation and necrosis of blood vessels. Directory of Open Access Journals (DOAJ), Google Scholar, Pubmed (NLM), LISTA (EBSCO) and Web of Science have been searched. Two major autoantigens for ANCA are myeloperoxidase (MPO) and proteinase 3 (PR3), which are proteins in the primary granules of neutrophils and in the lysosomes of monocytes. They are expressed in mature neutrophils of patients with ANCA, while absent in healthy subjects. The kidney is the most commonly affected vital organ in ANCA-associated vasculitis, and patient outcomes are largely determined by the severity of renal disease at diagnosis and by its response to treatment.

    Small-vessel vasculitis is a convenient descriptor for a wide range of diseases characterized by vascular inflammation of the venules, capillaries, and/or arterioles with pleomorphic clinical manifestations. The classical clinical phenotype is leucocytoclastic vasculitis with palpable purpura, but manifestations vary widely depending upon the organs involved. Histopathologic examination in leucocytoclastic vasculitis reveals angiocentric segmental inflammation, fibrinoid necrosis, and a neutrophilic infiltrate around the blood vessel walls with erythrocyte extravasation. The etiology of small-vessel vasculitis is unknown in many cases, but in others, drugs, post viral syndromes, malignancy, primary vasculitis such as microscopic polyarteritis, and connective tissue disorders are associated, The diagnosis of small- vessel vasculitis relies on a thorough history and physical examination, as well as relevant antibody testing including antinuclear antibody and anti neutrophil cytoplasmic antibody, hepatitis B and C serologies, assessment of complement, immunoglobulins, blood count, serum creatinine liver function tests, urinalysis, radiographic imaging and biopsy. The treatment is based primarily on corticosteroid and immunosuppressive agents.

  10. Classification system for acute and chronic radiation treatment sequelae

    Seegenschmiedt, M.H.; Sauer, R.

    1993-01-01

    A classification system in German language is proposed for scoring of acute and chronic treatment sequelae after radiotherapy. It includes all important organs and organ systems. The proposed grading corresponds to the four-scale-system of the WHO and UICC. The system is also compatible to the RTOG and EORTC acute and late radiation morbidity scoring criteria. This facilitates the data transfer for retrospective and prospective analysis of monomodal and multimodal radiotherapy treatment regimes. We recommend to use this scoring system in all German speaking countries for multicentric prospective studies. It is possible, that organ-specific sophistications of the toxicity grading will be developed in the future. These additions should conform with (inter)national standards and apply the same four-scale grading of this classification system. (orig.) [de

    Distribution and marketing of chemicals require appropriate labelling of health, physical and environmental hazards according to the United Nations global harmonisation system (GHS). Labelling for (human) acute toxicity categories is based on experimental findings usually obtained by oral, dermal or inhalative exposure of rodents. There is a strong societal demand for replacing animal experiments conducted for safety assessment of chemicals. Fish embryos are considered as alternative to animal testing and are proposed as predictive model both for environmental and human health effects. Therefore, we tested whether LC50s of the fish embryo acute toxicity test would allow effectively predicting of acute mammalian toxicity categories. A database of published fish embryo LC50 containing 641 compounds was established. For these compounds corresponding rat oral LD50 were identified resulting in 364 compounds for which both fish embryo LC50 and rat LD50 was available. Only a weak correlation of fish embryo LC50 and rat oral LD50 was obtained. Fish embryos were also not able to effectively predict GHS oral acute toxicity categories. We concluded that due to fundamental exposure protocol differences (single oral dose versus water-borne exposure) a reverse dosimetry approach is needed to explore the predictive capacity of fish embryos.

  15. Drug-Induced Vasculitis: New Insights and a Changing Lineup of Suspects.

    Science.gov (United States)

    Grau, Rafael G

    2015-12-01

    An increasing number of therapeutic agents have been associated with a vasculitic syndrome. This usually involves small vessels, primarily capillaries, venules, and arterioles in leukocytoclastic vasculitis, small-vessel disease similar to an antineutrophil cytoplasmic antibody-related vasculitis, or mid-sized muscular arteries in a polyarteritis-like picture. Antineutrophil cytoplasmic antibodies are present in many cases of vasculitis regardless of the size of the vessel involved. Monoclonal antibodies used to treat many autoimmune disorders have become the most common agents associated with drug-induced vasculitis. Important advances in epigenetics, genetics, and neutrophil apoptosis are providing new insights into the pathogenesis of both drug-induced vasculitis and idiopathic vasculitis. Although management has not changed significantly in the past few years where withdrawal of the offending agent is the primary intervention, increasing awareness of drug-induced vasculitis can lead to earlier diagnosis and prevention of severe organ damage and fatalities.

    Mandrell, Joshua; Kranc, Christina L

    2016-08-01

    Levamisole is an immunomodulatory drug that was previously used to treat various medical conditions, including parasitic infections, nephrotic syndrome, and colorectal cancer. Over the last few years, increasing amounts of levamisole have been used as an adulterant in cocaine. Levamisole-cut cocaine has become a concern because it is known to cause a necrotizing purpuric rash, autoantibody production, and life-threatening leukopenia. Mixed histologic findings of vasculitis and thrombosis are characteristic of levamisole-induced purpura. The recommended management of levamisole-induced vasculitis currently involves withdrawal of the culprit along with supportive treatment. We describe a patient with levamisole-induced vasculitis who continued to develop skin lesions despite self-reported cocaine cessation. Complete resolution of cutaneous disease occurred with the addition of oral prednisone and vardenafil hydrochloride, suggesting the possibility of a new treatment option in patients with refractory disease. In addition, we review the clinical presentation, disease course, diagnostic approach, laboratory findings, histology, and management of levamisole-induced vasculitis. The harmful effects of levamisole-cut cocaine are serious enough that public alerts have been issued to increase awareness. Clinicians should consider the possibility of levamisole exposure in cocaine users presenting with any combination of fever, neutropenia, and necrotic skin lesions, especially in acral areas including the ears.

    Vitamin K antagonists are widely used in thromboembolic diseases. Hemorrhagic complications related to drug overdose represent their main side effect. We report a rare side effect, a severe and unexpected type of skin vasculitis - necrotic leg ulcer - induced by vitamin K antagonist. A 63-year-old female with a history of diabetes developed hyperalgesic necrotic ulcerations on the lower limbs one month after starting an acenocoumarol-based treatment for ischemic heart disease. Histological examination revealed lymphocytic vasculitis with fibrinoid necrosis. Etiological explorations searching for vasculitis were negative. In the absence of a precise etiology, drug-induced ulcer was suspected. Low molecular weight heparin was prescribed to replace acenocoumarol. The lesions slowly resolved with topical treatment. The chronological criteria and the negativity of etiological explorations allowed the diagnosis of vitamin K antagonist-induced necrotic skin ulcer. Clinicians should be aware of this rare complication induced by oral anticoagulants because of its practical therapeutic implications. This is the first case of necrotic leg ulcer induced by acenocoumarol corresponding histologically to necrotising lymphocytic vasculitis. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Science.gov (United States)

    Teng, Gim Gee; Chatham, W Winn

    2015-04-01

    Vasculitis due to infection may occur as a consequence of the inflammation of vessel walls due to direct or contiguous infection, type II or immune complex-mediated reaction, cell-mediated hypersensitivity, or inflammation due to immune dysregulation triggered by bacterial toxin and/or superantigen production. As immunosuppressive therapy administered in the absence of antimicrobial therapy may increase morbidity and fail to effect the resolution of infection-associated vascular inflammation, it is important to consider infectious entities as potential inciting factors in vasculitis syndromes. The causality between infection and vasculitis has been established in hepatitis B-associated polyarteritis nodosa (HBV-PAN) and hepatitis C-associated (cryoglobulinemic) vasculitis (HCV-CV). The review summarizes the recent literature on the pathophysiological mechanisms and the approaches to the management of HBV-PAN and HCV-CV. Roles of other viral and microbial infections, which either manifest as vasculitic syndromes or are implicated in the pathogenesis of primary vasculitides, are also discussed. Copyright © 2015.

    Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis is a severe condition encompassing two major syndromes: granulomatosis with polyangiitis (formerly known as Wegener\\'s granulomatosis) and microscopic polyangiitis. Its cause is unknown, and there is debate about whether it is a single disease entity and what role ANCA plays in its pathogenesis. We investigated its genetic basis.

    We report the case of a 84-year-old man, with history of rheumatoid arthritis, admitted the Hospital for a fall and complaining of dysaesthesia and pain located to the cervical spine and arms. Within a few hours after admission, fever and acute, progressive, ascendant quadriplegia became evident. Magnetic resonance imaging (MRI) of cervical spine showed spinal canal stenosis between C4-C6 with spinal cord compression. Hemocultures resulted positive for Staphylococcus aureus. The clinical picture rapidly evolved to sepsis with a fatal multi-organ failure. An autopsy found a osteosclerosis narrowing the neurocanal at the level of C3-C6, and recent cervical medulla infarction. A histological exam revealed the presence of a suppurative pachymeningitis with local phenomenas of periradiculitis, vasculitis and thrombosis of the anterior medullar artery, associated with coagulative necrosis of the neural tissue.

    End-stage renal disease develops in a high percentage of patients with vasculitis, in whom kidney transplant has become a therapeutic option. However, limited data are available on the prognosis and outcomes after kidney transplant in these patients. We aimed to compare the long-term graft survival and graft function in 8 renal transplant recipients with vasculitis (granulomatosis with polyangiitis, microscopic polyangiitis, Goodpasture syndrome, and Henoch-Schonlein purpura) with the other kidney recipients at a single center. We conducted a retrospective study of patients followed for chronic renal failure associated with vasculitis before renal transplant. We excluded patients with no biopsy-proven nephropathy. There was no difference in the occurrence of metabolic and cardiovascular complications in our case group compared with the other graft recipients. Infections were frequent and included cytomegalovirus and urinary tract infection. The rates of bacterial and viral infection were equivalent in our population. The incidence of allograft loss was estimated at 1.8%, less than that seen in our entire transplant population. The presence of vasculitis was not significantly related to renal failure (P = .07). Extrarenal relapse occurred in 1 patient with microscopic polyangiitis. Antineutrophil cytoplasmic antibody levels in patients with granulomatosis with polyangiitis and microscopic polyangiitis did not seem to influence the renal outcome (P = .08). Circulating antineutrophil cytoplasmic antibodies were associated with the development of vascular lesions in the graft but were not significantly correlated with graft survival (P = .07). This study supports the theory that renal transplant is an effective treatment option for patients with end-stage renal disease secondary to vasculitis. These patients fare similarly to, if not better than, other patients.

    Acute hemorrhagic edema of infancy is one of the clinical forms of leukocytoclastic vasculitis seen in children. The condition runs a benign course. We report two male children who presented with upper respiratory tract infection followed by limb swelling and purpuric and ecchymotic lesions on the skin. Skin biopsy revealed leukocytoclastic vasculitis in both patients. In both cases, the lesions resolved completely without any sequelae.

    Early diagnosis of breast vasculitis (BV) is difficult because this condition is rare and occasionally mimics breast cancer clinically or radiologically. It may present as systemic disease or as an isolated lesion in the breast, without systemic evidence. When vasculitis appears in the breast, it also might manifest as a tumor-like lesion, and in previous cases, tissue acquisition was needed for confirmation of the diagnosis because of BV's resemblance to inflammatory breast cancer. We report a case of isolated BV that was suspected of being inflammatory breast cancer clinically, but manifested as bilateral breast edema on mammography. In this case, sonographic findings included not only nonspecific edema findings that might be seen in other cases, but also suggestive findings of hypoechoic circumferential arterial wall thickening with perivascular fat infiltrations that are similar to the halo sign in large arteries but have not been reported in the breast. These are helpful for presumptive diagnosis of BV using ultrasound.

  8. Oxaliplatin-Induced Leukocytoclastic Vasculitis under Adjuvant Chemotherapy for Colorectal Cancer: Two Cases of a Rare Adverse Event

    2013-12-01

    Full Text Available Leukocytoclastic vasculitis is a multicausal systemic inflammatory disease of the small vessels, histologically characterized by inflammation and deposition of both nuclear debris and fibrin in dermal postcapillary venules. The clinical picture typically involves palpable purpura of the lower legs and may be associated with general symptoms such as fatigue, arthralgia and fever. Involvement of the internal organs, most notably the kidneys, the central nervous system or the eyes, is possible and determines the prognosis. Oxaliplatin-induced leukocytoclastic vasculitis is a very rare event that limits treatment options in affected patients. We report 2 patients who developed the condition under chemotherapy for advanced rectal and metastatic colon carcinoma, respectively; a termination of the therapy was therefore necessary. While current therapies for colorectal cancer include the combination of multimodal treatment with new and targeted agents, rare and unusual side effects elicited by established agents also need to be taken into account for the clinical management.

    In vivo acute systemic testing is a regulatory requirement for agrochemical formulations. GHS specifies an alternative computational approach (GHS additivity formula) for calculating the acute toxicity of mixtures. We collected acute systemic toxicity data from formulations that contained one of several acutely-toxic active ingredients. The resulting acute data set includes 210 formulations tested for oral toxicity, 128 formulations tested for inhalation toxicity and 31 formulations tested for dermal toxicity. The GHS additivity formula was applied to each of these formulations and compared with the experimental in vivo result. In the acute oral assay, the GHS additivity formula misclassified 110 formulations using the GHS classification criteria (48% accuracy) and 119 formulations using the USEPA classification criteria (43% accuracy). With acute inhalation, the GHS additivity formula misclassified 50 formulations using the GHS classification criteria (61% accuracy) and 34 formulations using the USEPA classification criteria (73% accuracy). For acute dermal toxicity, the GHS additivity formula misclassified 16 formulations using the GHS classification criteria (48% accuracy) and 20 formulations using the USEPA classification criteria (36% accuracy). This data indicates the acute systemic toxicity of many formulations is not the sum of the ingredients' toxicity (additivity); but rather, ingredients in a formulation can interact to result in lower or higher toxicity than predicted by the GHS additivity formula.

    Objective To identify biomarkers that distinguish between active ANCA-associated vasculitis (AAV) and remission in a manner superior or complementary to established markers of systemic inflammation. Methods Markers of vascular injury and angiogenesis were measured before and after treatment in a large clinical trial in AAV. 163 subjects enrolled in the Rituximab in ANCA-Associated Vasculitis (RAVE) trial were studied. Serum levels of E-selectin, ICAM-3, MMP1, MMP3, MMP9, P-selectin, thrombomodulin, and VEGF were measured at study screening (time of active disease) and at month 6. ESR and CRP levels had been measured at the time of the clinical visit. The primary outcome was the difference in marker level between screening and month 6 among patients in remission (BVAS/WG score of 0) at month 6. Results All subjects had severe active vasculitis (mean BVAS/WG score 8.6 +/− 3.2 SD) at screening. Among the 123 subjects clinically in remission at month 6, levels of all markers except E-selectin showed significant declines. MMP3 levels were also higher among the 23 subjects with active disease at month 6 than among the 123 subjects in remission. MMP3 levels correlated weakly with ESR and CRP. Conclusion Many markers of vascular injury and angiogenesis are elevated in severe active AAV and decline with treatment, but MMP3 appears to distinguish active AAV from remission better than the other markers studied. Further study of MMP3 is warranted to determine its clinical utility in combination with conventional markers of inflammation and ANCA titers. PMID:21953143

    Objective The antineutrophil cytoplasmic antibody–associated vasculitides (AAV) are multiorgan diseases. Patients with AAV report impairment in their health-related quality of life (HRQOL) and have different priorities regarding disease assessment compared with physicians. The Outcome Measures in Rheumatology (OMERACT) Vasculitis Working Group previously received endorsement for a core set of domains in AAV. Two approaches to measure patient-reported outcomes (PRO) were presented at OMERACT 2016. Methods A novel 5-step tool was used to facilitate assessment of the instruments by delegates: the OMERACT Filter 2.0 Instrument Selection Algorithm, with a red-amber-green checklist of questions, including (1) good match with domain (face and content validity), (2) feasibility, (3) do numeric scores make sense (construct validity)?, (4) overall ratings of discrimination, and (5) can individual thresholds of meaning be defined? Delegates gave an overall endorsement. Three generic Patient-Reported Outcomes Measurement Information System (PROMIS) instruments (fatigue, physical functioning, and pain interference) and a disease-specific PRO, the AAV-PRO (6 domains related to symptoms and HRQOL), were presented. Results OMERACT delegates endorsed the use of the PROMIS instruments for fatigue, physical functioning, and pain interference (87.6% overall endorsement) and the disease-specific AAV-PRO instrument (89.4% overall endorsement). Conclusion The OMERACT Vasculitis Working Group gained endorsement by OMERACT for use of the PROMIS and the AAV-PRO in clinical trials of vasculitis. These instruments are complementary to each other. The PROMIS and the AAV-PRO need further work to assess their utility in longitudinal settings, including their ability to discriminate between treatments of varying efficacy in the setting of a randomized controlled trial.

    Eosinophilic/T-cell chorionic vasculitis (ETCV) is an inflammatory lesion of placental fetal vessels. In contrast to acute chorionic vasculitis, inflammation in ETCV is seen in chorionic vessel walls opposite the amnionic surface. It is not known whether inflammation in ETCV consists of maternal cells from the intervillous space or fetal cells migrating from the vessel. We used fluorescent in situ hybridization (FISH) to differentiate fetal versus maternal cells in ETCV. Placentas with ETCV, previously identified for a published study, were used. Infant sex in each case was identified using the electronic medical record. For male infants, 3-μm sections were cut from archived tissue blocks from placentas involving ETCV and stained with fluorescent X- and Y-chromosome centromeric probes. A consecutive hematoxylin/eosin-stained section was used for correlation. FISH analysis was performed on 400 interphase nuclei at the site of ETCV to determine the proportion of XX, XY, X, and Y cells. Of 31 ETCV cases, 20 were female and 10 were male (1 sex not recorded). Six of 10 cases with male infants had recuts with visible ETCV. In these 6 cases the average percentages (ranges) of XY cells, X-only cells, and Y-only cells in the region of inflammation were 81 (70-90), 11 (6-17), and 8 (2-14), respectively. There was a 2:1 female:male infant ratio in ETCV. Similar to acute chorionic vasculitis, the inflammation in ETCV is of fetal origin. It is still unknown, however, whether the stimulus for ETCV is of fetal or maternal origin.

It occurs due to cocaine adulterated with levamisole. Levamisole was once used as a chemotherapy and immunomodulator for different conditions. One of the side effects of this medication is necrotizing vasculitis which has been reported in the US and Puerto Rico. Here we present another case of cocaine induced vasculitis in Puerto Rico. We describe a 43-year-old female with past medical history of bronchial asthma, migraine, and crack smoking who presented to the emergency room due to blood in her urine for 5 days. She also reported fever, chills, and fatigue. At the physical exam she had a right knee ulcer with swelling erythema, warmth, and pain. Also, she had retiform purpuric plaque lesions in her ears, bilaterally. Eroded plaques with elevated borders at left foot and finger dorsum were also present. Laboratory workup was positive for cocaine. The patient showed leucopenia and microcytic anemia with a normal absolute neutrophil count in her cell blood count. Blood cultures, urine cultures, and ulcer cultures were negative. Urinalysis was positive for proteinuria and hematuria. Also, the patient had positive perinuclear anti-neutrophil cytoplasmic antibody, cytoplasmic anti-neutrophil cytoplasmic antibody, and antinuclear antibody tests and elastase specificity. She showed negative anticardiolipin and lupus anticoagulant antibodies. Her complement levels were decreased. The punch biopsy of her ear showed superficial thrombosis of superficial vascular plexus with perivascular lymphocytic infiltrates and deeper sections showed epidermal necrosis and necrotizing vasculitis. She was started on a high dose of steroids, but

    Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is histologically characterized by systemic necrotizing vasculitis and is clinically classified into two phases, systemic or localized. Recently, otological symptoms such as otitis media and hearing loss, not previously often associated with AAV, have been reported in AAV cases. In these cases we propose a diagnosis of otitis media with AAV (OMAAV). The ANCA titer is important for the diagnosis of OMAAV, and in most cases rapid progressive hearing loss is observed as localized AAV. Peripheral facial nerve palsy or hypertrophic pachymeningitis are coupled with 25% of cases and 18% of cases respectively. Proteinase 3-ANCA (PR3-ANCA) positive otitis media causes granulomatous formation or middle ear effusion in the middle ear, on the other hand myeloperoxidase-ANCA (MPO-ANCA) positive otitis media predominantly presents as otitis media with effusion. The early diagnosed case and the sensorineural hearing loss not progressed deaf could be recovered by the immunosuppressive therapy. Delayed diagnosis of AAV occasionally leads to progression to the irreversible phase; therefore, diagnosis at the early-localized stage is important for treating AAV. In this review, we discuss the current understanding of this newly proposed concept of OMAAV.

    Urticarial Vasculitis (UV) is in most of the cases idiopathic; however it has been associated with several conditions and drugs. Over the counter (OTC) diet pills are widely available, even on-line, but they are rarely regulated by pharmaceutical control. We present the case of a 35-year-old female patient suffering of pruriginous and painful wheals more than 1 cm in diameter, with a burning sensation. The eruption lasted more than 24 hours and was accompanied by angioedema, headache and myalgia. No remarkable medical history was found, except for previous intake of OTC diet pills. UV diagnosis was confirmed by the skin biopsy of a lesion. OTC diet pills are widely available worldwide, and due to its widespread use, allergologists and dermatologist should be able to recognize symptoms and lesions of cutaneous vasculitis, which may be under reported.

    Small-vessel vasculitis is a convenient descriptor for a wide range of diseases characterized by vascular inflammation of the venules, capillaries, and/or arterioles with pleomorphic clinical manifestations. The classical clinical phenotype is leucocytoclastic vasculitis with palpable purpura, but manifestations vary widely depending upon the organs involved. Histopathologic examination in leucocytoclastic vasculitis reveals angiocentric segmental inflammation, fibrinoid necrosis, and a neutrophilic infiltrate around the blood vessel walls with erythrocyte extravasation. The etiology of small-vessel vasculitis is unknown in many cases, but in others, drugs, post viral syndromes, malignancy, primary vasculitis such as microscopic polyarteritis, and connective tissue disorders are associated, The diagnosis of small- vessel vasculitis relies on a thorough history and physical examination, as well as relevant antibody testing including antinuclear antibody and anti neutrophil cytoplasmic antibody, hepatitis B and C serologies, assessment of complement, immunoglobulins, blood count, serum creatinine liver function tests, urinalysis, radiographic imaging and biopsy. The treatment is based primarily on corticosteroid and immunosuppressive agents

    2018-05-01

    Full Text Available Abstract Hydralazine is a direct-acting vasodilator, which has been used in treatment for hypertension (HTN since the 1950s. While it is well known to cause drug-induced lupus (DIL, recent reports are indicating the emergence of the drug-induced anti-neutrophil cytoplasmic antibody (ANCA associated vasculitis (DIV. Herein, we describe two patients (aged 57 and 87 years who presented with severe acute kidney injury (AKI, proteinuria, and hematuria. Both were receiving hydralazine for the treatment of hypertension. ANCA serology was positive in both patients along with anti-histone antibodies (commonly seen in drug-induced vasculitis. Renal biopsy revealed classic crescentic (pauci-immune glomerulonephritis in these patients and hydralazine was discontinued. During the hospital course, the 57-year-old patient required dialysis therapy and was treated with steroids and rituximab for the ANCA disease. Renal function improved and the patient was discharged (off dialysis with a serum creatinine of 3.6 mg/dL (baseline = 0.9 mg/dL. At a follow-up of 2 years, the patient remained off dialysis with advanced chronic kidney disease (CKD (stage IIIb. The 87-year-old patient had severe AKI with serum creatinine at 10.41 mg/dL (baseline = 2.27 mg/dL. The patient required hemodialysis and was treated with steroids, rituximab, and plasmapheresis. Unfortunately, the patient developed catheter-induced bacteremia and subsequently died of sepsis. Hydralazine can cause severe AKI resulting in CKD or death. Given this extremely unfavorable adverse-event profile and the widespread availability of alternative anti-hypertensive agents, the use of hydralazine should be carefully considered.

    2006-01-01

    Isolated (localized) idiopathic granulomatous vasculitis (IGV) is an uncommon, heterogeneous, and poorly defined group of disorders characterized by infiltration of the arterial wall caused by compactly grouped mononuclear phagocytes, with or without giant cells, in segmental distribution. We report on a 55-year-old woman with IGV limited to an intramuscular lipoma of the left thigh. The vasculitis was identified incidentally upon microscopic examination of the removed tumor. The IGV was centered on two medium-sized arteries, accompanied by narrowing of the lumens, and not associated with secondary changes such as infart or postinfart fibrosis. The inflammatory infiltrate was rich in T-lymphocytes and macrophages, with the presence of giant cells. The patient was asymptomatic and well in a follow-up period of 2 months, during which she was not treated. To our knowledge, this is the first report of lipoma involvement in localized IGV. It is important to distinguish cases of isolated intratumorous IGV from systemic disease, because the latter implies a poor prognosis and requires an aggressive treatment.

    Objective Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a group of linked multisystem life- and organ-threatening diseases. The Outcome Measures in Rheumatology (OMERACT) vasculitis working group has been at the forefront of outcome development in the field and has achieved OMERACT endorsement of a core set of outcomes for AAV. Patients with AAV report as important some manifestations of disease not routinely collected through physician-completed outcome tools; and they rate common manifestations differently from investigators. The core set includes the domain of patient-reported outcomes (PRO). However, PRO currently used in clinical trials of AAV do not fully characterize patients’ perspectives on their burden of disease. The OMERACT vasculitis working group is addressing the unmet needs for PRO in AAV. Methods Current activities of the working group include (1) evaluating the feasibility and construct validity of instruments within the PROMIS (Patient-Reported Outcome Measurement Information System) to record components of the disease experience among patients with AAV; (2) creating a disease-specific PRO measure for AAV; and (3) applying The International Classification of Functioning, Disability and Health to examine the scope of outcome measures used in AAV. Results The working group has developed a comprehensive research strategy, organized an investigative team, included patient research partners, obtained peer-reviewed funding, and is using a considerable research infrastructure to complete these interrelated projects to develop evidence-based validated outcome instruments that meet the OMERACT filter of truth, discrimination, and feasibility. Conclusion The OMERACT vasculitis working group is on schedule to achieve its goals of developing validated PRO for use in clinical trials of AAV.

    Objective To identify circulating proteins that distinguish between active anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) and remission in a manner complementary to markers of systemic inflammation. Methods Twenty-eight serum proteins representing diverse aspects of the biology of AAV were measured before and 6 months after treatment in a large clinical trial of AAV. Subjects (n=186) enrolled in the Rituximab in ANCA-Associated Vasculitis (RAVE) trial were studied. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels were available for comparison. The primary outcome was the ability of markers to distinguish severe AAV (Birmingham Vasculitis Activity Score for Wegener’s granulomatosis (BVAS/WG)≥3 at screening) from remission (BVAS/WG=0 at month 6), using areas under receiver operating characteristic (ROC) curve (AUC). Results All subjects had severe active vasculitis (median BVAS/WG=8) at screening. In the 137 subjects in remission at month 6, 24 of the 28 markers showed significant declines. ROC analysis indicated that levels of CXCL13 (BCA-1), matrix metalloproteinase-3 (MMP-3) and tissue inhibitor of metalloproteinases-1 (TIMP-1) best discriminated active AAV from remission (AUC>0.8) and from healthy controls (AUC>0.9). Correlations among these markers and with ESR or CRP were low. Conclusions Many markers are elevated in severe active AAV and decline with treatment, but CXCL13, MMP-3 and TIMP-1 distinguish active AAV from remission better than the other markers studied, including ESR and CRP. These proteins are particularly promising candidates for future studies to address unmet needs in the assessment of patients with AAV. PMID:22975753

  6. Static and fatigue tensile properties of cross-ply laminates containing vascules for self-healing applications

    International Nuclear Information System (INIS)

    Luterbacher, R; Trask, R S; Bond, I P

    2016-01-01

    The effect of including hollow channels (vascules) within cross-ply laminates on static tensile properties and fatigue performance is investigated. No change in mechanical properties or damage formation is observed when a single vascule is included in the 0/90 interface, representing 0.5% of the cross sectional area within the specimen. During tensile loading, matrix cracks develop in the 90° layers leading to a reduction of stiffness and strength (defined as the loss of linearity) and a healing agent is injected through the vascules in order to heal them and mitigate the caused degradation. Two different healing agents, a commercial low viscosity epoxy resin (RT151, Resintech) and a toughened epoxy blend (bespoke, in-house formulation) have been used to successfully recover stiffness under static loading conditions. The RT151 system recovered 75% of the initial failure strength, whereas the toughened epoxy blend achieved a recovery of 67%. Under fatigue conditions, post healing, a rapid decay of stiffness was observed as the healed damage re-opened within the first 2500 cycles. This was caused by the high fatigue loading intensity, which was near the static failure strength of the healing resin. However, the potential for ameliorating (via self-healing or autonomous repair) more diffuse transverse matrix damage via a vascular network has been shown. (paper)

    IgA vasculitis (IgAV) is a leukocytoclastic vasculitis and characterized by involvement of small vessels in skin, gastrointestinal system, joints, kidneys, and less frequently other organs. It is the commonest vasculitis in childhood and etiology is not completely known. Neurological manifestations of IgAV are very rare and usually seen in patients with severe hypertension or as an uncommon feature such as peripheral neuropathy. Posterior reversible encephalopathy syndrome (PRES) is a clinic-radiologic entity characterized with temporary vasogenic edema developing typically in posterior circulation of the brain and has been reported as a rare manifestation of IgAV. In this paper, a PRES case of 14-year-old male with IgAV is reported and etiopathogenesis was discussed with literature. Diagnosis was made by magnetic resonance imaging because of the existence of neurological symptoms (headache and visual loss) during the course of disease. His radiological findings have resolved with therapy. Although neurological involvement is a rare manifestation in IgAV, we recommend magnetic resonance imaging in such patients for diagnosis and evaluation of complications. Copyright © 2017.

    Full Text Available RESUMEN: Se presenta el caso clínico de una mujer de 81 años con antecedentes patología pulmonar obstructiva crónica "idiopática" que desarrolló un cuadro de insuficiencia renal aguda aparentemente prerrenal, con posterior oliguria y eosinofilia simulando una nefropatía túbulo-intersticial alérgica. La evolución atípica y la presencia de p-ANCA, sugerían una vasculitis, patología que se confirmó con la biopsia renal. Los resultados anatomopatológicos revelaron la existencia de una glomerulonefritis necrotizante con semilunas e infiltrado eosinófilo. Estos datos y el historial de la paciente llevaron al diagnóstico de vasculitis de Churg-Strauss. El tratamiento inicial con corticoides y ciclofosfamida y posteriormente con Azatioprina mostró excelentes resultados con mejoría de la función renal, de los parámetros inflamatorios y de la clínica sistémica, que la paciente mantuvo posteriormente. ABSTRACT: We report a case of a 81 year-old woman with idiopathic chronic obstructive pulmonary disease, who developed a functional acute renal failure with delayed oliguria and eosinophily, simulating an acute interstitial nephropathy. The unusual clinical course and the presence of antimyeloperoxidase antibodies (p-ANCA suggested a vasculitis; the renal biopsy confirmed this diagnosis. The histology revealed a crescentic glomerulonephritis with eosinophilic infiltration. With these data and the pulmonary history of the patient, a diagnosis of Churg-Struss Vasculitis was made. The initial treatment with steroids and ciclophosphamide switched later to azatioprine, was succeeded with a sustained improvement in renal function, inflammatory markers and clinical course.

    The sarcoidosis is a systemic granulomatosis affecting most frequently the lungs and the mediastinum. An acute renal failure reveals exceptionally this disease. It's a retrospective study implicating 12 cases of sarcoidosis complicated of acute renal failure. The aim of this study is to determine epidemiological, clinical, biological and histological profile in these cases and then to indicate the interest to consider the diagnosis of sarcoidosis in cases of unexplained renal failure. Extra-renal complications, therapeutic modalities and the outcome were determined in all patients. Our series involved 12 women with an average age of 40 years. Biological investigations showed an abnormal normocalcemia in 7 cases, a hypercalcemia in 5 cases, a hypercalciuria in 10 cases and polyclonal hypergammaglobulinemia in 7 cases. An acute renal failure was found in all patients with a median creatinin of 520 umol/L. For all patients, the renal echography was normal however, the kidney biopsy showed tubulo-interstitial nephritis. The extra-renal signs highlighting pulmonary interstitial syndrome in 5 cases, a sicca syndrome in 4 cases, mediastinal lymph nodes in 2 cases, a lymphocytic alveolitis in 3 cases, an anterior granulomatous uveitis in 2 cases and a polyarthritis in 5 cases. Five patients benefited of hemodialysis. The treatment consisted of corticosteroid in all cases. The follow up was marked by complete resolution of clinical and biological signs. The diagnosis of renal sarcoidosis must be done quickly to prevent renal failure.

    Mixed cryoglobulinemia syndrome (MC) is a systemic vasculitis involving kidneys, joints, skin, and peripheral nerves. While many autoimmune, lymphoproliferative, and neoplastic disorders have been associated with this disorder, hepatitis C virus (HCV) is known to be the etiologic agent in the majority of patients. Therefore, clinical research has focused on anti-viral drugs and, more recently, on the new, highly potent Direct-acting Antiviral Agents (DAAs). These drugs assure sustained virologic response (SVR) rates >90%. Nevertheless, data on their efficacy in patients with HCV-associated cryoglobulinemic vasculitis are disappointing, possibly due to the inability of the drugs to suppress the immune-mediated process once it has been triggered.Despite the potential risk of exacerbation of the infection, immunosuppression has traditionally been regarded as the first-line intervention in cryoglobulinemic vasculitis, especially if renal involvement is severe. Biologic agents have raised hopes for more manageable therapeutic approaches, and Rituximab (RTX), an anti CD20 monoclonal antibody, is the most widely used biologic drug. It has proved to be safer than conventional immunosuppressants, thus substantially changing the natural history of HCV-associated cryoglobulinemic vasculitis by providing long-term remission, especially with intensive regimens.The present review focuses on the new therapeutic opportunities offered by the combination of biological drugs, mainly Rituximab, with DAAs.

    Sphingosine 1-phosphate (S1P) is a bioactive lipid that binds to cell surface receptors (S1P 1-5 ). In this study, we examined the effect of S1P 1 agonist, ONO-W061, on murine Candida albicans water-soluble fraction (CAWS)-induced vasculitis. Mice were administered ONO-W061, and the number of peripheral blood cells was counted. Vasculitis was induced by an intraperitoneal injection of CAWS. Expression of S1P receptors and CXCL1 was analyzed by quantitative RT-PCR. ONO-W061 was orally administered, and vasculitis was evaluated histologically. Number of neutrophils, macrophages and T cells in the vasculitis tissue was counted using flow cytometry. Production of chemokines from S1P-stimulated human umbilical vein endothelial cells (HUVECs) was measured by ELISA. Number of peripheral blood lymphocytes was decreased by ONO-W061. Expression of CXCL1 and S1P 1 was enhanced in CAWS-induced vasculitis tissue. Vasculitis score, CXCL1 and number of neutrophils in the vasculitis tissue were lower in ONO-W061-treated mice. Treatment of HUVECs with S1P upregulated the production of CXCL1 and IL-8 in vitro, and this was inhibited by ONO-W061. ONO-W061 significantly improved CAWS-induced vasculitis. This effect may be partly exerted through the inhibited production of chemokines by endothelial cells, which in turn could induce neutrophil recruitment into inflamed vessels.

    after the discovery of antineutrophil cytoplasmic antibodies in 1982, and current classifications include Goodpasture's syndrome, forms of vasculitis related to antineutrophil cytoplasmic antibodies, forms caused by immune complexes and other forms. The evidence that antineutrophil cytoplasmic antibodies are involved in the pathogenesis of such conditions led to considerable advances in the diagnosis and treatment of vasculitis. Wegener's granulomatosis, Churg-Strauss syndrome and microscopic polyangiitis, all forms of vasculitis that have been associated with antineutrophil cytoplasmic antibodies, are the systemic forms that most affect the lungs. The most common presentation of such forms is characterized by cough, diffuse alveolar hemorrhage or difficult-to-control asthma. In Takayasu's arteritis, Behçet's disease and Henoch-Schönlein purpura, as well as in forms of vasculitis related to collagen diseases, pulmonary involvement is less common. In all forms of vasculitis, there is evidence that immune system processes are involved. It is based on this knowledge that new therapeutic approaches are proposed.

    2011-01-01

    Acute otitis media (AOM) is a common condition in children that is often treated with systemic antibiotic therapy; however, research suggests that non-complicated AOM will resolve spontaneously using only eardrops. To determine best practice for the use of systematic antibiotics compared to topical treatment of AOM, a systematic review of evidence was conducted. Cochrane, Medline, CINAHL, and other databases were searched. Inclusion criteria were studies published from 1995-2010 that included children with AOM and were randomized controlled trials (RCTs). Five systematic reviews and five RCTs were included in the review. Current evidence recommends using topical and other alternative approaches for treating non-complicated AOM in children 2 years of age or older; however, many practitioners are not currently following these recommendations for various reasons. Additional research to address these reasons may help determine how to improve practitioner adherence to best practice evidence and guidelines to help reduce the unnecessary use of systemic antibiotics.

    Small-vessel vasculitides are associated with antineutrophil cytoplasmic antibodies (ANCAs). Cytoplasmic ANCAs are targeted mainly against proteinase 3 (PR3), whereas myeloperoxidase (MPO) is the major antigen of perinuclear ANCAs. These relapsing vasculitides show heterogeneous clinical pictures, and disease severity may vary broadly from mild local organ manifestation to acute organ failure (eg, renal failure). We tested whether two cytokine polymorphisms in the interleukin-1beta (IL-1beta) and IL-1 receptor antagonist (IL-1ra) genes, known to determine cytokine secretion, are associated with clinical manifestations and outcome of ANCA-associated vasculitides. Polymerase chain reaction and restriction fragment length polymorphism analyses were performed to determine polymorphisms in the IL-1beta and IL-1ra genes in 79 patients with PR3-ANCA, 30 patients with MPO-ANCA vasculitis, and 196 healthy controls. The frequency of the so-called proinflammatory genotype, characterized by high secretion of IL-1beta and low secretion of its antagonist IL-1ra, was increased significantly in patients with PR3-ANCA with end-stage renal disease. Patients with a renal manifestation of PR3-ANCA vasculitis have an increased risk for developing end-stage renal disease when carrying the proinflammatory IL-1beta/IL-1ra genotype. Anti-inflammatory therapy specifically antagonizing the proinflammatory effect of IL-1beta may be a promising treatment for patients with Wegener's granulomatosis with renal manifestations.

    While on our general inpatient rehabilitation floor, a 58-year-old man with no hematologic or dermatologic history developed an erythematous patch on his medial ankle that turned more purpuric, with a slight orange tint, and was associated with mild pruritus. The diagnosis of exercise-induced vasculitis was made after initially being mistaken for cellulitis. This common exanthem is often misdiagnosed. Due to its association with exercise, the physiatrist should be aware of its presence in both the inpatient and outpatient settings.

  5. Diagnostic Utility of Contrast-enhanced 3D T1-weighted Imaging in Acute Cerebral Infarction Associated with Graves Disease.

    Graves disease is rarely complicated with cerebrovascular steno-occlusive diseases. Previous studies have suggested several hypotheses for this occurrence, including excess thyroid hormone, which stimulates the sympathetic nervous system, which in turn causes an abnormal hemodynamic response with consequent atherosclerotic changes, and antithyroid antibodies cause local vascular inflammation in patients with Graves disease. However, radiological findings of vasculitis in patients with Graves disease and cerebral infarction remain less known. We report the case of a 30-year-old Japanese woman with acute cerebral infarction due to vasculitis associated with Graves disease. She was admitted to our hospital with a 4-day history of intermittent transient dysarthria and limb shaking of the left leg when standing. Three weeks before admission, she went to a local hospital because of general malaise and was diagnosed with Graves disease. Neurological examination revealed paralytic dysarthria, left central facial nerve palsy, and left hemiparesis (manual muscle testing, 4 of 5). Blood examinations showed hyperthyroidism (thyroid-stimulating hormone ≤.010 µU/mL; free T3 ≥25.0 pg/mL; free T4 ≥8.0 ng/dL) and elevation of antithyroid antibody levels (thyroid peroxidase antibody, 87 IU/mL). The vessel wall of the right internal carotid artery was markedly enhanced on contrast-enhanced three-dimensional T1-weighted magnetic resonance imaging, suggesting vasculitis. Magnetic resonance angiography revealed right internal carotid artery occlusion after the branching ophthalmic artery. Arterial stenosis due to vasculitis was considered the cause of hemodynamic ischemic stroke. Vessel wall imaging such as high-resolution contrast-enhanced T1-weighted imaging seems useful for assessing the underlying mechanism of stroke in patients with Graves disease.

    Full Text Available Acute hemorrhagic edema of infancy is a rare form of leukocytoclastic vasculitis. Mostly it appears under three years of age and is characterized by purpuric skin lesions, fever and edema. A three years-old boy, who has cough and coryzea was admitted to our clinic for fever and red spots on legs and arms. In physical examination; ecimotic skin lesions on right ear, face, arms, dorsal of the hands, buttocks, legs and dorsal of the feet were found. In the laboratory tests acute phase reactants were elevated and blood coagulation tests were in normal range. Hepatit A,B,C and TORCH markers were negative. Punch biopsy obtained from gluteal area showed leukositoclastic vasculity. Focal fibrinogen accumulation was detected by immun fluorescent microscopy. Regression on lesions was not observed despite supportive therapy, so prednisolone (1 mg/kg/day therapy was started. On the third day of the steroid therapy, complete recovery was achived.

    Antineutrophil cytoplasmatic antibodies (ANCA)-associated vasculitides (Wegener's granulomatosis, microscopic polyangiitis, Churg-Strauss syndrome) show quite variable courses. Clinical features of the full blown generalized systemic vasculitis are usually found in the respiratory tract and the kidney. Pulmonary involvement of Wegener's granulomatosis shows commonly nodules and cavitations but also diffuse alveolar hemorrhage. We report the case of a 57 year-old man suffering from dyspnea, thoracal pain, arthralgia, purpura, scleritis and tinitus. Specimen of the kidney showed segmental glomerulosclerosis and tubulointerstitial nephritis. Because of the presence of cANCA Wegener's disease was assumed. Pulmonary infiltrates developed under immunosuppressive treatment with cyclophosphamid. As differential diagnosis of the pulmonary infiltrates, we considered invasive pulmonary aspergillosis as well as infiltrates due to Wegener's granulomatosis. In spite of maximal therapeutic management of patient died of respiratory and cardiovascular failure. The findings at autopsy showed distinct invasive pulmonary aspergillosis and perifocal hemorrhage.

    2016-01-01

    Full Text Available Anti-neutrophil cytoplasmic antibody-associated vasculitis is an uncommon inflammatory disease of small to medium-sized vessels that frequently presents with rapidly progressive glomerulonephritis and renal failure though it can affect any organ system. If untreated, the vast majority of patients will die within a year. Current treatments improve prognosis but affected patients remain at a substantially higher risk of death and adverse outcomes. We review the classification of the disease, our understanding of the pathogenesis and epidemiology, and propose future directions for research. We also evaluate the evidence supporting established treatment regimens and the progress of clinical trials for newer treatments to inform the design of future studies.

  11. Acute macular neuroretinopathy associated with systemic lupus erythematosus.

    Lee, D H; Lee, S C; Kim, M

    2016-04-01

    Acute macular neuroretinopathy (AMN) is a rare disorder that presents with abrupt visual change with wedge-shaped or flower-like lesions pointing towards the fovea. Ischemic insults to the retinal capillary plexus may be important for development of this disease. While many case reports have been published on AMN, none have described AMN in association with systemic lupus erythematosus (SLE). Here, we report a case of AMN associated with newly-diagnosed SLE. We speculate that in patients with lupus flares, immune complex-mediated vascular injury and microvascular thrombosis may disrupt the deep retinal capillary network, causing ischemic damages to the outer retina and leading to the development of AMN. AMN can develop in patients with lupus flares, and must be considered as an SLE-associated ophthalmologic complication. To the best of our knowledge, this is the first case report of AMN associated with SLE. © The Author(s) 2015.

  12. Eosinophils in vasculitis: characteristics and roles in pathogenesis

    Science.gov (United States)

    Khoury, Paneez; Grayson, Peter C.; Klion, Amy D.

    2016-01-01

    Eosinophils are multifunctional granular leukocytes that are implicated in the pathogenesis of a wide variety of disorders, including asthma, helminth infection, and rare hypereosinophilic syndromes. Although peripheral and tissue eosinophilia can be a feature of many types of small-vessel and medium-vessel vasculitis, the role of eosinophils has been best studied in eosinophilic granulomatosis with polyangiitis (EGPA), where eosinophils are a characteristic finding in all three clinical stages of the disorder. Whereas numerous studies have demonstrated an association between the presence of eosinophils and markers of eosinophil activation in the blood and tissues of patients with EGPA, the precise role of eosinophils in disease pathogenesis has been difficult to ascertain owing to the complexity of the disease process. In this regard, results of clinical trials using novel agents that specifically target eosinophils are providing the first direct evidence of a central role of eosinophils in EGPA. This Review focuses on the aspects of eosinophil biology most relevant to the pathogenesis of vasculitis and provides an update of current knowledge regarding the role of eosinophils in EGPA and other vasculitides.

    Full Text Available A 26-year-old male patient presented to our rheumatology clinic with pain, swelling and limitation of movement in his right ankle, and also purpuric skin lesions in the lower extremity pretibial region. He was asked questions, and he said that he had been having chronic low back pain and morning stiffness for the last few years. His physical examination revealed that he had arthritis in his right ankle, purpuric skin lesions in pretibial regions of both legs, and bilateral FABERE/FADIR positivity. The sacroiliac joint imaging and MRI revealed bilateral sacroiliitis findings, and the lateral heel imaging revealed enthesitis. HLA-B27 was positive. Skin biopsy from lower skin lesions was reported to be consistent with leukocytoclastic vasculitis. Based on clinical, laboratory, radiological, and pathological examinations, the patient was diagnosed with ankylosing spondylitis and leukocytoclastic vasculitis. Administration of corticosteroid, salazopyrin, and nonsteroid anti-inflammatory medications was started. Notable clinical and laboratory regression was observed during his checks 3 months later.

    Cerebral ischaemia caused by inflammatory vasculopathies has been described as complication of human immunodeficiency virus (HIV) infection. Imaging studies have shown ischaemic lesions and changes of the vascular lumen, but did not allow demonstration of abnormalities within the vessel wall itself. Two HIV-infected men presented with symptoms of a transient ischaemic attack. Initial MRI of the first showed no infarct; in the second two small lacunar lesions were detected. In both cases, multiplanar 3-mm slice contrast-enhanced T1-weighted images showed aneurysmal dilatation, with thickening and contrast enhancement of the wall of the internal carotid and middle cerebral (MCA) arteries. These findings were interpreted as indicating cerebral vasculitis. In the first patient the vasculopathy progressed to carotid artery occlusion, and he developed an infarct in the MCA territory, but then remained neurologically stable. In the second patient varicella zoster virus (VZV) infection was the probable cause of vasculitis. The clinical deficits and vasculitic MRI changes regressed with antiviral and immunosuppressive therapy. (orig.)

    In order to elucidate the mechanism of occurrence of radiation sickness, whole body irradiation of various doses of X-ray was done on male spontaneously hypertensive rats (SHR) whose sympathetic nervous system is functionally activated and on their original male Wistar Kyoto rats (WKY) and the change of their body weights was examined. Further, changes of blood pressure in rats irradiated at 7.5 Gy, of norepinephrine contents in their gut as a parameter of sympathetic nervous function and of acetylcholine contents as that of parasympathetic nervous function were measured. Histopathological examinations were also performed. SHR died at smaller dose than WKY. The blood pressure as a parameter of systemic sympathetic nervous system varied greatly in SHR. Norepinephrine contents elevated rapidly and greatly in SHR after irradiation and acetylcholine contents rapidly elevated in WKY. Apoptosis was more frequently observed in the intestinal crypt of SHR. Participation of autonomic nervous system was thus shown in the appearance of acute radiation injury and sickness in SHR, which was thought to be a useful model for the investigation. (K.H.)

    A 27-year-old Caucasian man was transferred from a remote clinic with acute kidney injury for the prior 7–10 days preceded by gastroenteritis. His kidney biopsy showed non-specific mesangiopathic glomerular changes, minimal tubulointerstitial disease without sclerosis, crescents, nor evidence of vasculitis. On his third hospital day, he developed acute hypoxic respiratory failure requiring intubation and mechanical ventilation. Pulmonary renal syndromes ranked highest on his differential diag...

    Wells' syndrome is defined as an inflammatory disorder with the histopathological presence of eosinophilic infiltrates and flame figures in the absence of vasculitis. Eosinophilic leukocytoclastic vasculitis shows eosinophilic infiltrates in combination with vasculitic changes. And Churg Strauss Syndrome comprises all three characteristics - eosinophilic infiltrates, vasculitis and flame figures. To determine whether these three diseases are distinct entities or different manifestations of a similar clinicopathologic process. Histopathological samples and clinical courses of 17 patients with eosinophilic infiltrates, flame figures and clinical features of Wells' syndrome were re-evaluated. Histopathologically, we focused on the presence or absence of vasculitic features. Clinically, we included only patients who were diagnosed with Wells' syndrome at least once in the course of their disease. 4 patients were finally diagnosed with Wells' syndrome, 5 with eosinophilic leukocytoclastic vasculitis and 6 with Churg Strauss syndrome. Further, we had one case of an overlap between Wells' syndrome and eosinophilic vasculitis and one case of Wegener granulomatosis. Vasculitic features were found in the samples of all patients. Histologically, we find vasculitic features in typical presentations of Wells' syndrome. Clinically, we find typical features of Wells' syndrome in patients finally diagnosed with eosinophilic leukocytoclastic vasculitis or Churg Strauss syndrome. Furthermore, we have observed and formerly reported 3 patients with progression from Wells' syndrome to Churg Strauss syndrome. Thus, we assume that eosinophilic leukocytoclastic vasculitis might form a bridge between Wells' syndrome and Churg Strauss syndrome.

    For acutely ill patients, health care services are available in many different settings, including hospital-based emergency departments (EDs), retail clinics, federally qualified health centers, and outpatient clinics. Certain conditions are the sole domain of particular settings: stabilization of critically ill patients can typically only be provided in EDs. By contrast, many conditions that do not require hospital resources, such as advanced radiography, admission, and same-day consultation can often be managed in clinic settings. Because clinics are generally not open nights, and often not on weekends or holidays, the ED remains the only option for face-to-face medical care during these times. For patients who can be managed in either setting, there are many open research questions about which is the best setting, because these venues differ in terms of access, costs of care, and potentially, quality. Consideration of these patients must be risk-adjusted, as patients may self-select a venue for care based upon perceived acuity. We present a research agenda for acute, unscheduled care in the United States developed in conjunction with an Agency for Healthcare Research and Quality-funded conference hosted by the American College of Emergency Physicians in October 2009, titled "Improving the Quality and Efficiency of Emergency Care Across the Continuum: A Systems Approach." Given the possible increase in ED utilization over the next several years as more people become insured, understanding differences in cost, quality, and access for conditions that may be treated in EDs or clinic settings will be vital in guiding national health policy. © 2011 by the Society for Academic Emergency Medicine.

    Acute myocardial infarction is the leading cause of non-communicable deaths worldwide. Its diagnosis is a highly complex task, for which modelling through automated methods has been attempted. A systematic review of the literature was performed on diagnostic tests that applied intelligent systems tools in the diagnosis of acute coronary syndromes. A systematic review of the literature is presented using Medline, Embase, Scopus, IEEE/IET Electronic Library, ISI Web of Science, Latindex and LILACS databases for articles that include the diagnostic evaluation of acute coronary syndromes using intelligent systems. The review process was conducted independently by 2 reviewers, and discrepancies were resolved through the participation of a third person. The operational characteristics of the studied tools were extracted. A total of 35 references met the inclusion criteria. In 22 (62.8%) cases, neural networks were used. In five studies, the performances of several intelligent systems tools were compared. Thirteen studies sought to perform diagnoses of all acute coronary syndromes, and in 22, only infarctions were studied. In 21 cases, clinical and electrocardiographic aspects were used as input data, and in 10, only electrocardiographic data were used. Most intelligent systems use the clinical context as a reference standard. High rates of diagnostic accuracy were found with better performance using neural networks and support vector machines, compared with statistical tools of pattern recognition and decision trees. Extensive evidence was found that shows that using intelligent systems tools achieves a greater degree of accuracy than some clinical algorithms or scales and, thus, should be considered appropriate tools for supporting diagnostic decisions of acute coronary syndromes.

    IgA vasculitis, a rare condition resulting in end-stage renal disease, is a small-vessel vasculitis that affects the kidney in 49-83 % of adults. The reported recurrence rate of IgA vasculitis in renal transplant recipients is 11.5-60 %, leading to graft loss in 0-50 % of these patients. However, limited data are available on recurrence and graft loss after renal transplantation. We evaluated renal transplant recipients seen from 1987 to 2015 at the Jikei University School of Medicine and the Department of Urology, Tokyo Women's Medical University. Using a 1:2 match, 21 patients with IgA vasculitis and 42 controls were selected. The mean post-transplant follow-up was 121 ± 69 months for IgA vasculitis and 147 ± 66 months for the controls. The 15-year patient survival was 100 % in IgA vasculitis and 97.6 % in the controls (p = 0.22). The 5-, 10-, and 15-year graft survival rates were 95.2, 90.5, and 81 % in IgA vasculitis and 100, 90.5, and 88.1 % in the controls, respectively (p = 0.63). The recurrence rate was 28.6 % (6 of 21 cases) and half of them (3 of 6 cases) showed histological activity (ISKDC III). We treated them with methylprednisolone pulse therapy and/or tonsillectomy. None of the recurrence cases lost the allograft. The long-term patient and graft survival of IgA vasculitis in renal transplantation were comparable with the previous reports. The recurrence rate was 28.6 %, but none of the recurrent cases showed allograft loss in this study. We speculate that methylprednisolone pulse therapy and/or tonsillectomy prevent the progression of recurrent IgA vasculitis.

    Acute brain injuries cause rapid cell death that activates bidirectional crosstalk between the injured brain and the immune system. In the acute phase, the damaged CNS activates resident and circulating immune cells via the local and systemic release of soluble mediators. This early immune activation is necessary to confine the injured tissue and foster the clearance of cellular debris, thus bringing the inflammatory reaction to a close. In the chronic phase, a sustained immune activation has been described in many CNS disorders, and the degree of this prolonged response has variable effects on spontaneous brain regenerative processes. The challenge for treating acute CNS damage is to understand how to optimally engage and modify these immune responses, thus providing new strategies that will compensate for tissue lost to injury. Herein we have reviewed the available information regarding the role and function of the innate and adaptive immune responses in influencing CNS plasticity during the acute and chronic phases of after injury. We have examined how CNS damage evolves along the activation of main cellular and molecular pathways that are associated with intrinsic repair, neuronal functional plasticity and facilitation of tissue reorganization.

    2018-01-01

    Full Text Available A 69-year-old female with antisynthetase syndrome, a history of multiple recurrent infections, and documented previous negative titres for anti-neutrophil cystoplasmic antibody (ANCA suddenly developed a de novo MPO-ANCA-associated glomerulonephritis three weeks after a fecal microbiota transplantation (FMT for recurrent Clostridium difficile infections. Six months following her FMT and less than two weeks following treatment for urosepsis, she developed severe cholestasis, a markedly elevated ferritin and hypertriglyceridemia. An initial liver biopsy was suggestive of drug-induced liver injury and thus she was treated with supportive care. After she failed to improve, a second liver biopsy supported the diagnosis of hemophagocytic lymphohistiocytosis (HLH. This case highlights difficulties surrounding the early diagnosis of HLH and also questions the role of FMT and/or recurrent infections as a trigger for ANCA-associated vasculitis.

    Acute otitis media (AOM) is a common acute infection in children. Pain is its most prominent and distressing symptom. Antibiotics are commonly prescribed for AOM, although they have only a modest effect in reducing pain at two to three days. There is insufficient evidence for benefits of other treatment options, including systemic corticosteroids. However, systemic corticosteroids are potent anti-inflammatory drugs, and so theoretically could be effective, either alone or as an addition to antibiotics. To assess the effects of systemic corticosteroids (oral or parenteral), with or without antibiotics, for AOM in children. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) which contains the Cochrane ARI Group's Specialised Register, MEDLINE (Ovid), Embase (Elsevier), CINAHL (EBSCO), Web of Science (Thomson Reuters), and LILACS (BIREME) for published studies, and ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) for completed and ongoing studies, to 20 February 2018. We checked the reference lists of all primary studies and review articles for additional references and contacted experts in the field to identify additional unpublished materials. We included randomised controlled trials of children with AOM that compared any systemic corticosteroid (oral or parenteral) with placebo, either with antibiotics (corticosteroid plus antibiotic versus placebo plus antibiotic) or without antibiotics (corticosteroid versus placebo). Three review authors (EDS, RR, YP) independently screened the titles and abstracts and retrieved the full texts of potentially relevant studies. We independently extracted study characteristics and outcome data from the included studies, and assessed the risk of bias for each study using the criteria outlined in the Cochrane Handbook for Systematic Reviews of Interventions. We assessed study quality using the GRADE method. We included two studies involving 252

    2017-02-01

    Acute kidney injury (AKI) is a rapid loss of kidney function resulting in accumulation of end metabolic products and associated abnormalities in fluid, electrolyte and acid-base homeostasis. The pathophysiology of AKI is complex and multifactorial involving numerous vascular, tubular and inflammatory pathways. Neurohumoral activation with heightened activity of the sympathetic nervous system and renin-angiotensin-aldosterone system play a critical role in this scenario. Inflammation and/or local renal ischaemia are underlying mechanisms triggering renal tissue hypoxia and resultant renal microcirculation dysfunction; a common feature of AKI occurring in numerous clinical conditions leading to a high morbidity and mortality rate. The contribution of renal nerves to the pathogenesis of AKI has been extensively demonstrated in a series of experimental models over the past decades. While this has led to better knowledge of the pathogenesis of human AKI, therapeutic approaches to improve patient outcomes are scarce. Restoration of autonomic regulatory function with vagal nerve stimulation resulting in anti-inflammatory effects and modulation of centrally-mediated mechanisms could be of clinical relevance. Evidence from experimental studies suggests that a therapeutic splenic ultrasound approach may prevent AKI via activation of the cholinergic anti-inflammatory pathway. This review briefly summarizes renal nerve anatomy, basic insights into neural control of renal function in the physiological state and the involvement of the autonomic nervous system in the pathophysiology of AKI chiefly due to sepsis, cardiopulmonary bypass and ischaemia/reperfusion experimental model. Finally, potentially preventive experimental pre-clinical approaches for the treatment of AKI aimed at sympathetic inhibition and/or parasympathetic stimulation are presented. © 2016 John Wiley & Sons Australia, Ltd.

    Horse serum-induced immune complex coronary vasculitis in swine is the first experimental model to mimic most of the pictures of Kawasaki disease. Immune complex mechanism has been implicated as one of the possible mechanisms in the pathogenesis of vasculitis in Kawasaki disease. Antioxidants have a significant role in the reduction of cardiovascular diseases in both human and animal studies. We tried giving vitamins A, E, and C to treat immune complex vasculitis, in the hope of mitigating coronary vasculitis in Kawasaki disease. Our study group consisted of 30 pure bred male piglets of 2-3 months of age, and they were divided into test and control groups. The test (AEC) group (n = 20) received two doses of horse serum, 10 mL (0.65 g protein)/kg body weight at 5-day intervals, and oral vitamins A, E, and C once daily for 14 days. The control group (n = 10) was further divided into the saline group (n = 3) receiving two doses of normal saline and the horse serum group (n = 7) receiving two doses of horse serum at 5-day intervals. Piglets were observed for the rashes and coronary artery dimensions. Both the AEC and the control horse serum group developed rashes after horse serum infusions, but the AEC group developed significantly fewer rashes, and no rashes were seen in the saline group. The control horse serum group (mean ± standard deviation = 2.13 ± 0.72) showed significant coronary artery dilatation, whereas there was no significant dilatation in the AEC group (mean ± standard deviation = 0.81 ± 0.58) or the control saline group (p = 0.002). Serum sickness is a prototype of immune complex vasculitis, and the severity can be ameliorated with antioxidants. A trial of therapeutic dosages of vitamins A, E, and C in acute phase of Kawasaki disease, may be effective in mitigation of coronary artery lesion in addition to intravenous immunoglobulin and aspirin.

    Full Text Available Vehicle parking is the act of temporarily maneuvering a vehicle in to a certain location. To deal with parking monitoring system issue such as traffic, this paper proposes a vision of improvements in monitoring the vehicles in parking lots based on sensor networks. Most of the existing paper deals with that of the automated parking which is of cluster based and each has its own overheads like high power, less energy efficiency, incompatible size of lots, space. The novel idea in this work is usage of CoAP (Constrained Application Protocol which is recently created by IETF (draft-ietf-core-coap-18, June 28, 2013, CoRE group to develop RESTful application layer protocol for communications within embedded wireless networks. This paper deals with the enhanced CoAP protocol using multi hop flat topology, which makes the acuters feel soothe towards parking vehicles. We aim to minimize the time consumed for finding free parking lot as well as increase the energy efficiency

    Published small case series suggest that inflammatory bowel disease [IBD; Crohn's disease (CD) or ulcerative colitis (UC)] and vasculitis co-occur more frequently than would be expected by chance. To describe this association by an analysis of a large cohort of carefully studied patients and through a systematic literature review. Patients with both IBD and vasculitis enrolled in the Vasculitis Clinical Research Consortium (VCRC) Longitudinal Studies, followed in Canadian Vasculitis research network (CanVasc) centers and/or in the University of Toronto's IBD clinic were included in this case series. A systematic literature review of patients with IBD and vasculitis involved a PubMed search through February 2014. The main characteristics of patients with Takayasu arteritis (TAK) and IBD were compared to those in patients with TAK without IBD followed in the VCRC. The study identified 32 patients with IBD and vasculitis: 13 with large-vessel vasculitis [LVV; 12 with TAK, 1 with giant cell arteritis (GCA); 8 with CD, 5 with UC]; 8 with ANCA-associated vasculitis [AAV; 6 granulomatosis with polyangiitis (GPA), 2 with eosinophilic granulomatosis with polyangiitis (EGPA)]; 5 with isolated cutaneous vasculitis; and 6 with other vasculitides. Patients with LVV and AAV were mostly female (18/21). The diagnosis of IBD preceded that of vasculitis in 12/13 patients with LVV and 8/8 patients with AAV. The review of the literature identified 306 patients with IBD and vasculitis: 144 with LVV (133 TAK; 87 with IBD preceding LVV), 19 with AAV [14 GPA, 1 EGPA, 4 microscopic polyangiitis (MPA)], 66 with isolated cutaneous vasculitis, and 77 with other vasculitides. Patients with IBD and TAK were younger and had more frequent headaches, constitutional symptoms, or gastrointestinal symptoms compared to those patients in the VCRC who had TAK without IBD. These findings highlight the risk of vasculitis, especially TAK, in patients with IBD (both CD and UC). Copyright © 2015 Elsevier

    With previous methods based on only age and location, there are many difficulties in identifying the etiology of acute abdominal pain in children. We sought to develop a new systematic classification of acute abdominal pain and to give some helps to physicians encountering difficulties in diagnoses. From March 2005 to May 2010, clinical data were collected retrospectively from 442 children hospitalized due to acute abdominal pain with no apparent underlying disease. According to the final diagnoses, diseases that caused acute abdominal pain were classified into nine groups. The nine groups were group I "catastrophic surgical abdomen" (7 patients, 1.6%), group II "acute appendicitis and mesenteric lymphadenitis" (56 patients, 12.7%), group III "intestinal obstruction" (57 patients, 12.9%), group IV "viral and bacterial acute gastroenteritis" (90 patients, 20.4%), group V "peptic ulcer and gastroduodenitis" (66 patients, 14.9%), group VI "hepatobiliary and pancreatic disease" (14 patients, 3.2%), group VII "febrile viral illness and extraintestinal infection" (69 patients, 15.6%), group VIII "functional gastrointestinal disorder (acute manifestation)" (20 patients, 4.5%), and group IX "unclassified acute abdominal pain" (63 patients, 14.3%). Four patients were enrolled in two disease groups each. Patients were distributed unevenly across the nine groups of acute abdominal pain. In particular, the "unclassified abdominal pain" only group was not uncommon. Considering a systemic classification for acute abdominal pain may be helpful in the diagnostic approach in children.

    Purpose: to investigate the role of FDG-PET and PET/CT in the evaluation of vasculitis. Materials and methods: a systematic revision of the papers published in PubMed/Medline until December 2009 was done. Results: FDG-PET and PET/CT have been proven to be valuable in the diagnosis of large-vessel vasculitis, especially giant cells arteritis with sensitivity values ranging 77% to 92%, and specificity values ranging 89% to 100%. In particular, FDG-PET/CT has demonstrated the potential to non-invasively diagnose the onset of the vasculitis earlier than traditional anatomical imaging techniques, thus enabling prompt treatment. False positive results mainly occur in the differential diagnosis between vasculitis and atherosclerotic vessels in elderly patients. Another area where FDG-PET/CT is gaining wider acceptance is in monitoring response to therapy; it can reliably detect the earliest changes of disease improvement post-therapy, and persistent activity is an indicator of non-responders to therapy. A few data have been reported about medium/small vessel vasculitis. Discussion: FDG-PET and PET/CT have proven utility: (a) in the initial diagnosis of patients suspected of having vasculitis particularly in those who present with non-specific symptoms; (b) in the identification of areas of increased FDG uptake in which a biopsy should be done for obtaining a diagnosis; (c) in evaluating the extent of the disease; (d) in assessing response to treatment.

    Early detection of acute lung injury (ALI) is essential for timely implementation of evidence-based therapies and enrollment into clinical trials. We aimed to determine the accuracy of computerized syndrome surveillance for detection of ALI in hospitalized patients and compare it with routine clinical assessment. Using a near-real time copy of the electronic medical records, we developed and validated a custom ALI electronic alert (ALI "sniffer") based on the European-American Consensus Conference Definition and compared its performance against provider-derived documentation. A total of 3,795 consecutive critically ill patients admitted to nine multidisciplinary intensive care units (ICUs) of a tertiary care teaching institution were included. ALI developed in 325 patients and was recognized by bedside clinicians in only 86 (26.5%). Under-recognition of ALI was associated with not implementing protective mechanical ventilation (median tidal volumes of 9.2 vs. 8.0 ml/kg predicted body weight, P sniffer" demonstrated excellent sensitivity of 96% (95% CI 94-98) and moderate specificity of 89% (95% CI 88-90) with a positive predictive value ranging from 24% (95% CI 13-40) in the heart-lung transplant ICU to 64% (95% CI 55-71) in the medical ICU. The computerized surveillance system accurately identifies critically ill patients who develop ALI syndrome. Since the lack of ALI recognition is a barrier to the timely implementation of best practices and enrollment into research studies, computerized syndrome surveillance could be a useful tool to enhance patient safety and clinical research.

    Full Text Available As vasculites pulmonares primárias são caracterizadas por processo inflamatório na parede dos vasos pulmonares que leva a isquemia e hemorragia pulmonar com as conseqüentes expressões clínicas e radiológicas. As vasculites pulmonares primárias são acompanhadas de expressão sistêmicas cutâneas, em nervos periféricos, rins, seios da face, olhos e ouvidos, além do trato gastrintestinal, e sistemas cardíaco e nervoso central. O diagnóstico é feito através da associação das informações clínicas, radiológicas e anatomopatológicas. O tratamento com corticosteróides e imunossupressores deve ser instituído precocemente e apresenta altas taxas de remissão.The primary forms of pulmonary vasculitis are characterized by an inflammatory process in the pulmonary vessel walls, leading to pulmonary ischemia and hemorrhage and the consequent clinical and radiological manifestations. These forms of vasculitis are accompanied by symptoms involving the skin, peripheral nerves, kidneys, sinuses, eyes, ears and gastrointestinal tract, as well as the cardiac and central nervous systems. The diagnosis is made through analysis of the clinical, radiological and pathological data. When treatment with corticosteroids and immunosuppressive therapy is initiated early, remission rates are high.

    Hypocomplementemic urticarial vasculitis (HUV) is an uncommon vasculitis of unknown etiology that is rarely described in the literature. We undertook this study to analyze the clinical spectrum and the therapeutic management of patients with HUV. We conducted a French nationwide retrospective study that included 57 patients with chronic urticaria, histologic leukocytoclastic vasculitis, and hypocomplementemia. We assessed clinical and laboratory data and evaluated the patients' cutaneous and immunologic responses to therapy. We evaluated treatment efficacy by measuring the time to treatment failure. Urticarial lesions were typically more pruritic than painful and were associated with angioedema in 51% of patients, purpura in 35%, and livedo reticularis in 14%. Extracutaneous manifestations included constitutional symptoms (in 56% of patients) as well as musculoskeletal involvement (in 82%), ocular involvement (in 56%), pulmonary involvement (in 19%), gastrointestinal involvement (in 18%), and kidney involvement (in 14%). Patients with HUV typically presented with low C1q levels and normal C1 inhibitor levels, in association with anti-C1q antibodies in 55% of patients. Hydroxychloroquine or colchicine seemed to be as effective as corticosteroids as first-line therapy. In patients with relapsing and/or refractory disease, rates of cutaneous and immunologic response to therapy seemed to be higher with conventional immunosuppressive agents, in particular, azathioprine, mycophenolate mofetil, or cyclophosphamide, while a rituximab-based regimen tended to have higher efficacy. Finally, a cutaneous response to therapy was strongly associated with an immunologic response to therapy. HUV represents an uncommon systemic and relapsing vasculitis with various manifestations, mainly, musculoskeletal and ocular involvement associated with anti-C1q antibodies, which were found in approximately half of the patients. The best strategy for treating HUV has yet to be defined

    Full Text Available A 42 year old man presented with acute bilateral uveitis and necrotizing retinitis. Systemic investigations including test for AIDS and CMV retinitis were negative. Despite oral Acyclovir, both eyes progressed rapidly to retinal detachment with loss of vision. Early recognition is necessary to diagnose the bilateral acute retinal necrosis syndrome and initiate treatment. Bilateral acute retinal necrosis (BARN is a term first coined by Young and Bird in 1978 although the syndrome had been originally described by Urayama et al as an unilateral condition. This syndrome is characterized by the triad of acute confluent peripheral necrotizing retinitis, moderate to severe vasculitis and vitritis in an otherwise healthy individual. Rhegmatogenous retinal detachment occurs within two to three months of the onset of the disease and the second eye is involved in 36% of patients, usually within 6 weeks. We herein report a patient who presented with simultaneous BARN leading to retinal detachment in a matter of days. Also, to our knowledge this is the first report of this condition in India.

    This study determined whether interleukin-10 (IL-10) polymorphisms are associated with susceptibility to vasculitis. A meta-analysis was conducted of the associations between the IL-10 -1082 G/A, -819 C/T, and -592 C/A polymorphisms and the haplotype of the IL-10-1082 G/A, -819 C/T, -592 C/A polymorphisms and vasculitis. A total of 21 comparative studies involving 4121 patients and 5504 controls were considered in the meta-analysis. Meta-analysis revealed no association between the IL-10-1082 G allele and vasculitis in all study subjects (OR = 0.927, 95% CI = 0.780-1.102, p = 0.389). However, disease-specific meta-analysis showed an association between Wegener's granulomatosis (WG) and the IL-10-1082 G allele (OR = 0.729, 95% CI = 0.547-0.971, p = 0.031). Meta-analysis revealed an association between vasculitis and the IL-10-819 C allele (OR = 0.804, 95% CI = 0.706-0.916, p = 0.001) in all study subjects and Behcet's disease (BD) (OR = 0.724, 95% CI = 0.679-0.781, p vasculitis in all study subjects (OR = 0.805, 95% CI = 0.619-0.938, p = 0.005) and BD (OR = 0.718, 95% CI = 0.661-0.781, p vasculitis in Europeans (OR = 1.239, 95% CI = 1.105-1.513, p = 0.035). This meta-analysis showed that IL-10 polymorphisms are associated with vasculitis susceptibility, especially in WG and BD.

    [ 18 F]FDG-PET is a non-invasive metabolic imaging modality based on the regional distribution of fluorine-18-fluorodeoxyglucose that is highly effective in assessing the activity and the extent of giant cell arteritis and Takayasu's arteritis. It has shown to identify more affected vascular regions than morphologic imaging with Magnetic Resonance Imaging in both diseases. A visual grading of vascular [ 18 F]FDG-uptake helps to discriminate arteritis from atherosclerosis und therefore provides high specificity. High sensitivity is reached by scanning during the active inflammatory phase. [ 18 F]FDG-PET has the potential to develop into a valuable tool in the diagnostic work-up of giant cell arteritis and Takayasu's arteritis, respectively, and might become a first-line investigation technique. Therefore consensus regarding the most favorable imaging procedure as well as further clinical evidence is needed. The purpose of this review is to summarize current information on the present clinical data and to assist nuclear medicine practitioners in recommending, performing and interpreting the results of [ 18 F]FDG-PET in patients with suspected large vessel vasculitis.

    We characterized the complete genome of a novel dog circovirus (DogCV) from the liver of a dog with severe hemorrhagic gastroenteritis, vasculitis, and granulomatous lymphadenitis. DogCV was detected by PCR in fecal samples from 19/168 (11.3%) dogs with diarrhea and 14/204 (6.9%) healthy dogs and in blood from 19/409 (3.3%) of dogs with thrombocytopenia and neutropenia, fever of unknown origin, or past tick bite. Co-infection with other canine pathogens was detected for 13/19 (68%) DogCV-positive dogs with diarrhea. DogCV capsid proteins from different dogs varied by up to 8%. In situ hybridization and transmission electron microscopy detected DogCV in the lymph nodes and spleens of 4 dogs with vascular compromise and histiocytic inflammation. The detection of a circovirus in tissues of dogs expands the known tropism of these viruses to a second mammalian host. Our results indicate that circovirus, alone or in co-infection with other pathogens, might contribute to illness and death in dogs.

    Central nervous system infiltration and relapse are poorly understood in childhood acute lymphoblastic leukemia. We examined the role of zeta-chain-associated protein kinase 70 in preclinical models of central nervous system leukemia and performed correlative studies in patients. Zeta-chain-associated protein kinase 70 expression in acute lymphoblastic leukemia cells was modulated using short hairpin ribonucleic acid-mediated knockdown or ectopic expression. We show that zeta-chain-associated protein kinase 70 regulates CCR7/CXCR4 via activation of extracellular signal-regulated kinases. High expression of zeta-chain-associated protein kinase 70 in acute lymphoblastic leukemia cells resulted in a higher proportion of central nervous system leukemia in xenografts as compared to zeta-chain-associated protein kinase 70 low expressing counterparts. High zeta-chain-associated protein kinase 70 also enhanced the migration potential towards CCL19/CXCL12 gradients in vitro CCR7 blockade almost abrogated homing of acute lymphoblastic leukemia cells to the central nervous system in xenografts. In 130 B-cell precursor acute lymphoblastic leukemia and 117 T-cell acute lymphoblastic leukemia patients, zeta-chain-associated protein kinase 70 and CCR7/CXCR4 expression levels were significantly correlated. Zeta-chain-associated protein kinase 70 expression correlated with central nervous system disease in B-cell precursor acute lymphoblastic leukemia, and CCR7/CXCR4 correlated with central nervous system involvement in T-cell acute lymphoblastic leukemia patients. In multivariate analysis, zeta-chain-associated protein kinase 70 expression levels in the upper third and fourth quartiles were associated with central nervous system involvement in B-cell precursor acute lymphoblastic leukemia (odds ratio=7.48, 95% confidence interval, 2.06-27.17; odds ratio=6.86, 95% confidence interval, 1.86-25.26, respectively). CCR7 expression in the upper fourth quartile correlated with central

En este trabajo informamos dos casos con dicha asociación describiendo sus características clínicas, tomográficas e inmunológicas. Dado que en la asociación de FP y VAA notificada en los últimos años, la FP puede ser su primera manifestación, podría ser necesaria la búsqueda de ANCA en pacientes con FP, como causa de la misma y por el posible desarrollo posterior de vasculitis.The most frequently observed pulmonary complications of vasculitis (AAV with anti-neutrophil cytoplasmic positive antibodies (ANCA are alveolar hemorrhage, granulomas and airway stenosis. In recent years, some reports have been published that show the association of vasculitis with pulmonary fibrosis (PF, suggesting that it may be another complication of AAV. We report and describe here two cases with such association, and their clinical, tomographic and immunological characteristics. Given that in the association between PF and AAV, as reported in the last years, PF could be the first manifestation of AAV, the search for ANCA in patients with PF may be necessary, as a cause of it and for the possible subsequent development of vasculitis.

    We investigated the clinical and serological features of patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) in Japan using data from a nationwide, prospective, inception cohort study. In total, 156 Japanese patients with newly diagnosed AAV were classified according to the European Medicines Agency (EMEA) algorithm with exploratory surrogate markers for AAV-related non-granulomatous pulmonary lesions, predefined as alveolar haemorrhage and interstitial lung disease (ILD), and their clinical and serological features were evaluated. Using the EMEA algorithm, we identified 14 patients (9.0%) with eosinophilic granulomatosis with polyangiitis (EGPA), 33 (21.2%) with granulomatosis with polyangiitis (GPA), 78 (50.0%) with microscopic polyangiitis and renal-limited vasculitis (MPA/RLV), and 31 (19.9%) with unclassifiable vasculitis. The average ages of patients with EGPA (male/female, 5/9), GPA (12/21), and MPA/RLV (35/43) and unclassifiable (9/22) were 58.0, 63.6, 71.1, and 70.6 years, respectively. Myeloperoxidase (MPO)-ANCA and proteinase-3 ANCA positivity was 50.0% and 0% for EGPA, 54.6% and 45.5% for GPA, 97.4% and 2.6% for MPA/RLV, and 93.5% and 3.2% for unclassifiable, respectively. According to the Birmingham Vasculitis Activity Score (BVAS), cutaneous (71.4%) and nervous system (92.9%) manifestations were prominent in EGPA and ear, nose, and throat manifestations (84.9%) and chest manifestations (66.7%) in GPA. Renal manifestations developed frequently in MPA/RLV (91.0%) and GPA (63.6%). The average serum creatinine levels were 0.71 mg/dL for EGPA, 1.51 mg/dL for GPA, 2.46 mg/dL for MPA/RLV, and 0.69 mg/dL for unclassifiable. The percentages of patients with ILD were 14.3% for EGPA, 9.0% for GPA, 47.4% for MPA/RLV, and 61.3% for unclassifiable. Patients with ILD (n = 61) had significantly lower BVAS (P = 0.019) with fewer ear, nose, and throat and cardiovascular manifestations than patients without ILD (n = 95). MPO

    The objective of this study was to determine whether interleukin-1 (IL-1) polymorphisms are associated with susceptibility to vasculitis. A meta-analysis was conducted to investigate possible associations between IL-1A, IL-1B, and IL-1 receptor antagonist (IL1RN) polymorphisms and vasculitis. A total of 17 studies involving 1384 vasculitis cases [Behçet's disease (BD), IgA vasculitis, anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), Kawasaki disease (KD), giant cell arteritis, and Takayasu's arteritis] and 2710 controls were included in the meta-analysis. This analysis showed an association between BD and the TT + TC genotypes of the IL-1A-889 C/T polymorphism in the entire study population [odds ratio (OR) = 0.623, 95 % CI = 0.395-0.981, p = 0.045), and a trend toward an association in a Turkish population (OR = 0.578, 95 % CI = 0.331-1.010, p = 0.054). A meta-analysis of the IL1RN polymorphism revealed no association with vasculitis in all study subjects (OR for IL1RN*2 = 0.904, 95 % CI = 0.626-1.304, p = 0.588). However, stratification by ethnicity revealed a significant association between the IL1RN*2 allele and vasculitis including AAV, BD, KD in Asians (OR = 2.393, 95 % CI = 1.429-4.006, p = 0.001), but not in Caucasian and Turkish populations (OR = 0.776, 95 % CI = 0.487-1.238, p = 0.288; OR = 0.914, 95 % CI = 0.667-1.252, p = 0.576, respectively). No association was found between vasculitis and the IL-1B-511 C/T polymorphism, or the IL-1B+3953 C/T polymorphism. This meta-analysis suggests that the IL-1A-889 C/T polymorphism is associated with susceptibility to BD, and that the IL1RN*2 allele is associated with susceptibility to vasculitis including AAV, BD, and KD in Asians.

    Acute Hemorrhagic Edema of Infancy is an infrequent leukocytoclastic vasculitis which occurs almost exclusively in children between 4 months and 2 years of age. It is clinically characterized by the triad fever, purpuric lesions on the face, auricular pinna and extremities, and edema. Although the cutaneous findings are dramatic and of rapid onset, the prognosis is favorable, with spontaneous resolution within 1 to 3 weeks. Three cases are described in which clinical and histopathological findings are characteristic of acute hemorrhagic edema of infancy.

    The past decade has seen a substantial increase in the number and quality of clinical trials of new therapies for vasculitis, including randomized, controlled, multicenter trials that have successfully incorporated measures of disease activity and toxicity. However, because current treatment regimens for severe disease effectively induce initial remission and reduce mortality, future trials will focus on any of several goals including: (a) treatment of mild—moderate disease; (b) prevention of chronic damage; (c) reduction in treatment toxicity; or (d) more subtle differences in remission induction or maintenance. Thus, new trials will require outcome measure instruments that are more precise and are better able to detect effective treatments for different disease states and measure chronic manifestations of disease. The OMERACT Vasculitis Working Group comprises international clinical investigators with expertise in vasculitis who, since 2002, have worked collaboratively to advance the refinement of outcome measures in vasculitis, create new measures to address domains of illness not covered by current research approaches, and harmonize outcome assessment in vasculitis. The focus of the OMERACT group to date has been on outcome measures in small-vessel vasculitis with an overall goal of creating a core set of outcome measures for vasculitis, each of which fulfills the OMERACT filter of truth, discrimination, feasibility, and identifying additional domains requiring further research. This process has been informed by several ongoing projects providing data on outcomes of disease activity, disease-related damage, multidimensional health-related quality of life, and patient-reported ratings of the burden of vasculitis.

    Objective Glomerulonephritis (GN) is common in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), but tools for early detection of renal involvement are imperfect. We investigated 4 urinary proteins as markers of active renal AAV: alpha-1 acid glycoprotein (AGP), kidney injury molecule-1 (KIM-1), monocyte chemoattractant protein-1 (MCP-1), and neutrophil gelatinase-associated lipocalin (NGAL). Methods Patients with active renal AAV (n = 20), active nonrenal AAV (n = 16), and AAV in longterm remission (n = 14) were identified within a longitudinal cohort. Urinary biomarker concentrations (by ELISA) were normalized for urine creatinine. Marker levels during active AAV were compared to baseline remission levels (from 1–4 visits) for each patient. Areas under receiver-operating characteristic curves (AUC), sensitivities, specificities, and likelihood ratios (LR) comparing disease states were calculated. Results Baseline biomarker levels varied among patients. All 4 markers increased during renal flares (p < 0.05). MCP-1 discriminated best between active renal disease and remission: a 1.3-fold increase in MCP-1 had 94% sensitivity and 89% specificity for active renal disease (AUC = 0.93, positive LR 8.5, negative LR 0.07). Increased MCP-1 also characterized 50% of apparently nonrenal flares. Change in AGP, KIM-1, or NGAL showed more modest ability to distinguish active renal disease from remission (AUC 0.71–0.75). Hematuria was noted in 83% of active renal episodes, but also 43% of nonrenal flares and 25% of remission samples. Conclusion Either urinary MCP-1 is not specific for GN in AAV, or it identifies early GN not detected by standard assessment and thus has potential to improve care. A followup study with kidney biopsy as the gold standard is needed. PMID:23547217

    Lung protective ventilation reduces mortality in patients with acute lung injury, but underrecognition of acute lung injury has limited its use. We recently validated an automated electronic acute lung injury surveillance system in patients with major trauma in a single intensive care unit. In this study, we assessed the system's performance as a prospective acute lung injury screening tool in a diverse population of intensive care unit patients. Patients were screened prospectively for acute lung injury over 21 wks by the automated system and by an experienced research coordinator who manually screened subjects for enrollment in Acute Respiratory Distress Syndrome Clinical Trials Network (ARDSNet) trials. Performance of the automated system was assessed by comparing its results with the manual screening process. Discordant results were adjudicated blindly by two physician reviewers. In addition, a sensitivity analysis using a range of assumptions was conducted to better estimate the system's performance. The Hospital of the University of Pennsylvania, an academic medical center and ARDSNet center (1994-2006). Intubated patients in medical and surgical intensive care units. None. Of 1270 patients screened, 84 were identified with acute lung injury (incidence of 6.6%). The automated screening system had a sensitivity of 97.6% (95% confidence interval, 96.8-98.4%) and a specificity of 97.6% (95% confidence interval, 96.8-98.4%). The manual screening algorithm had a sensitivity of 57.1% (95% confidence interval, 54.5-59.8%) and a specificity of 99.7% (95% confidence interval, 99.4-100%). Sensitivity analysis demonstrated a range for sensitivity of 75.0-97.6% of the automated system under varying assumptions. Under all assumptions, the automated system demonstrated higher sensitivity than and comparable specificity to the manual screening method. An automated electronic system identified patients with acute lung injury with high sensitivity and specificity in diverse

    Full Text Available Cocaine is a popular recreational drug in the United States, and up to 70% of the seized cocaine contains levamisole which is an antihelminthic that can cause cutaneous vasculitis with necrosis and positive antineutrophil cytoplasmic antibodies (ANCAs. Here, we report a unique case of recurrent cocaine-induced vasculitis in a patient who smokes cocaine for more than 20 years. A 38-year-old woman complained of painful erythematous rash in her right arm and right thigh which appeared some hours after smoking cocaine. Physical examination revealed tender, erythematous base, retiform purpura with necrosis and bullae. Serological test showed high atypical perinuclear ANCA titer of 1:320 and antimyeloperoxidase antibody level of 20.4 U/mL. Cocaine-induced vasculitis should be one of the differential diagnoses in cocaine abusers who present with painful rash and areas of necrosis. Early diagnosis is important since it is an emerging public health concern.

    Acute hemorrhagic edema of infancy (AHEI) is an unusual form of leukocytoclastic vasculitis with dramatic distinguishing skin lesions that occurs in infants ages 4 to 24 months old. The disease presents with skin eruptions that usually start with large (1-5 cm), symmetrically distributed, hemorrhagic lesions in a characteristic cockade pattern. The lesions are typically located on the lower extremities, face (in particular the ears, cheeks, and eyelids), and gluteal area. Fever may accompany skin eruptions. Clinical presentation at onset requires clinical and laboratory examination to distinguish it from more serious diseases and other vasculitis. The main differential diagnosis of AHEI is Henoch-Schönlein purpura. AHEI is generally a self-limiting disease, so a conservative approach should be considered. Topical or systemic corticosteroid therapy has been reported to be beneficial, as well as antihistamines and dapsone, although AHEI usually resolves completely with or without treatment. We report two cases of AHEI and an update of the literature. © 2012 Wiley Periodicals, Inc.

    B cell depletion therapy using rituximab has been shown to be effective in achieving remission in patients with HCV-mixed cryoglobulinemic (MC) vasculitis. Previously, we have demonstrated abnormalities in peripheral immune cells involving neutrophils, chemotaxis, and innate immune activation among patients with HCV-MC vasculitis when compared to HCV patients without vasculitis. In this study, we evaluated the effect of B cell depletion therapy on transcriptional profiles of peripheral blood mononuclear cells before and after riruximab therapy, in order to unravel the pathogenic mechanism involved in HCV-MC vasculitis induced by abnormal B cell proliferation. DNA microarray analysis was performed using RNA from PBMCs from seven patients with HCV-MC vasculitis and seven normal volunteers. DNA was hybridized to Affymetrix U133A chips. After normalization, differentially expressed gene list with treatment was generated using partitional clustering. RT-PCR, flow cytometry, and enzyme immunoassay (EIA) was used to validate DNA microarray findings. Differentially expressed genes included B cells and non-B cell genes. Validation of genes using purified cell subsets demonstrated distinct effect of B cell depletion therapy on non-B cells, such as monocytes, T cells, and NK cells. Notably, B lymphocyte stimulator (BLyS) levels were persistently elevated in patients who subsequently relapsed. In conclusion, pathogenesis of HCV-MC vasculitis is mediated by abnormal proliferation of B cells, driven by BLyS, leading to significant effects on non-B cells in mediating symptomatology. Future therapeutics using a combination approach of B cell depletion and proliferation may be desired to achieve long-term remission.

    A 59-year-old female with diffuse large B-cell lymphoma was treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) regimen. In addition, we administered pegfilgrastim for treating chemotherapy-induced febrile neutropenia. She complained of fever and neck and chest pain a few days after pegfilgrastim administration during the third and fourth courses of R-CHOP. Radiological imaging revealed an inflammation of large vessels, which led to the diagnosis of drug-associated vasculitis. We confirmed that vasculitis observed in this case was caused by pegfilgrastim administration because similar symptoms appeared with both injections of pegfilgrastim.

    We present the case of a 69-year-old woman with unilateral retinal vasculitis. Investigations showed asthma, rhinosinusitis, nasal polyposis, peripheral blood eosinophilia, increased sedimentation rate, proteinuria, and antiphospholipid antibodies. Anti-neutrophil cytoplasmic antibodies (ANCA) were negative. Although her anti-neutrophil cytoplasmatic antibody (ANCA) status was negative, taking into account the other clinical and laboratory features, retinal vasculitis was thought to be an ocular manifestation of Churg-Strauss syndrome. Treatment was started with high-dose corticosteroids and anticoagulant therapy. Copyright © 2016 Sociedad Española de Oftalmología. Publicado por Elsevier España, S.L.U. All rights reserved.

    Full Text Available Catecholamine-induced vasculitis is a well known but rarely described entity. However, aortoarteritis as a manifestation of catecholamine-induced vasculitis is not described in the literature. We have reported two patients in whom pheochromocytoma coexisted with aortoarteritis. Both patients were young females with history of bilateral pheochromocytomas in more than one first-degree relative. Both patients also had bilateral adrenal pheochromocytomas (second patient also had paraganglioma at left renal hilum with elevation of plasma free normetanephrine levels. We conclude that there may be an association between pheochromocytoma and aortoarteritis, and that catecholamine excess may have a role in the etiopathogenesis of aortoarteritis in these patients.

    Acute appendicitis is the most common surgical condition presented in emergency departments worldwide. Clinical scoring systems, such as the Alvarado and modified Alvarado scoring systems, were developed with the goal of reducing the negative appendectomy rate to 5%-10%. The Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) scoring system was established in 2008 specifically for Asian populations. The aim of this study was to compare the modified Alvarado with the RIPASA scoring system in Kuwait population. This study included 180 patients who underwent appendectomies and were documented as having "acute appendicitis" or "abdominal pain" in the operating theatre logbook (unit B) from November 2014 to March 2016. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), diagnostic accuracy, predicted negative appendectomy and receiver operating characteristic (ROC) curve of the modified Alvarado and RIPASA scoring systems were derived using SPSS statistical software. A total of 136 patients were included in this study according to our criteria. The cut-off threshold point of the modified Alvarado score was set at 7.0, which yielded a sensitivity of 82.8% and a specificity of 56%. The PPV was 89.3% and the NPV was 42.4%. The cut-off threshold point of the RIPASA score was set at 7.5, which yielded a 94.5% sensitivity and an 88% specificity. The PPV was 97.2% and the NPV was 78.5%. The predicted negative appendectomy rates were 10.7% and 2.2% for the modified Alvarado and RIPASA scoring systems, respectively. The negative appendectomy rate decreased significantly, from 18.4% to 10.7% for the modified Alvarado, and to 2.2% for the RIPASA scoring system, which was a significant difference (PAsian populations. It consists of 14 clinical parameters that can be obtained from a good patient history, clinical examination and laboratory investigations. The RIPASA scoring system is more accurate and specific than the modified Alvarado

    Primary angiitis of the central nervous system is a rare condition, usually with an insidious onset. There is a wide variety of histological types (granulomatous, lymphocytic or necrotizing vasculitis) and types of vessel involved (arteries, veins or both). Most cases are idiopathic. We describe a first case of idiopathic granulomatous central nervous system phlebitis with additional limited involvement of the heart and lung, exclusively affecting small and medium sized veins in a 22-year-old woman, presenting as a sub acute headache. The reasons for this peculiar limitation of inflammation to the veins and the involvement of the heart and lungs are unknown. © 2015 Japanese Society of Neuropathology.

    Acute systemic toxicity testing provides the basis for hazard labeling and risk management of chemicals. A number of international efforts have been directed at identifying non-animal alternatives for in vivo acute systemic toxicity tests. A September 2015 workshop, Alternative Approaches for Identifying Acute Systemic Toxicity: Moving from Research to Regulatory Testing, reviewed the state-of-the-science of non-animal alternatives for this testing and explored ways to facilitate implementation of alternatives. Workshop attendees included representatives from international regulatory agencies, academia, nongovernmental organizations, and industry. Resources identified as necessary for meaningful progress in implementing alternatives included compiling and making available high-quality reference data, training on use and interpretation of in vitro and in silico approaches, and global harmonization of testing requirements. Attendees particularly noted the need to characterize variability in reference data to evaluate new approaches. They also noted the importance of understanding the mechanisms of acute toxicity, which could be facilitated by the development of adverse outcome pathways. Workshop breakout groups explored different approaches to reducing or replacing animal use for acute toxicity testing, with each group crafting a roadmap and strategy to accomplish near-term progress. The workshop steering committee has organized efforts to implement the recommendations of the workshop participants. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Introduction. Nephropathy is diagnosed in 30–60 % of patients with hemorrhagic vasculitis (HV (Schönlein Henoch puprupa and occurred in each fourth of them in the onset of the disease and with the same incidence at first recurrence of the patho­logical process. In recent years, the relative and absolute number of patients with this form of glomerular disease significantly increased. According to the results of the kidney biopsy in children, Henoch glomerulonephritis (HGN is the most common variant of the secondary immunoglobulin (Ig A nephritis. The nature of the clinical course and morphological manifestations of the HGN in patients with HV, which began in childhood and adulthood, remains unexplored. This was the purpose and objectives of this study. Materials and methods. The study included 174 patients with HV (83 % of men and 47 % of women. In 92 cases, vasculitis debuted in children (on average in 12 years, and in 82 — in the adults (on average in 25 years. I, II and III degree of activity of pathological process are set at a ratio of 1 : 2 : 2. Seropositivity for high levels of IgA occurred in 40 % of cases, by the presence of rheumatoid factor — in 27 %. At the time of the survey, cutaneous syndrome was diagnosed in 68 % of patients in the form of urticarial, hemorrhagic, papule-nodular, papule-necro­tic, pustular-ulcerative, necrotic-ulcerative, nodose-ulcerative and polymorphic forms, and articular syndrome — in 48 %. In 24 cases, kidney biopsy was performed. Results. Renal disease was revealed in 71 % of patients with HV, while on the background of nephropathy the integral index of the severity of extrarenal patho­logy was significantly higher. According to the characteristics of the articular syndrome, patients with nephropathy and without it differed little among themselves. The severity of muscle syndrome has the impact on the development of the HV. In turn, renal pathology significantly influenced the development

    Full Text Available A 51-year-old man with type 2 diabetes mellitus and chronic obstructive pulmonary disease presented to the emergency room with increasing bilateral leg pain, rash, and scrotal swelling with pain. Skin biopsy from his thigh revealed IgA-associated vasculitis. Due to hematuria, a renal biopsy was performed and showed an IgA glomerulonephritis with focal fibrinoid necrosis and neutrophil accumulation. Bilateral orchiectomies were performed in two separate procedures ten and thirteen days after the renal biopsy, as a result of uncontrolled abscess formation in testicles. Microscopically, both testicles revealed large abscess formation destroying almost the entire testicular parenchyma without tumor cells. Spermatic cord margins were further scrutinized microscopically to show bilateral vasculitis in many small size vessels, confirmed by positive endothelial staining for IgA. Some of the affected arteries revealed central organizing thrombi with recanalization features, highly suggestive of vasculitis-associated thrombi formation, resulting in testicular ischemic infarction and abscess formation. We conclude that this adult patient developed a severe form of Henoch-Schönlein purpura, with vasculitis affecting multiple organs, including the most serious and unusual complication of bilateral testicular infarction.

    2017-06-01

    Full Text Available Objective: It is controversial whether microorganisms play a role in the pathogenesis of large and medium vessel vasculitides (eg, giant cell arteritis [GCA], Takayasu arteritis [TAK] and focal idiopathic aortitis [FIA]. Recent studies have reported the presence of Varicella Zoster Virus (VZV within formalin-fixed, paraffin-embedded temporal arteries and aortas of about three-quarters or more of patients with these conditions, and in a minority of controls. In a prospective study, we sought to confirm these findings using DNA extracted from vessels that were harvested under surgically aseptic conditions and snap frozen. Methods and Results: DNA samples extracted from 11 surgically sterile temporal arteries and 31 surgically sterile thoracic aortas were used in an attempt to identify the vessel-associated VZV genome. Two different validated PCR methods were used. Thirty-one thoracic aorta aneurysm specimens included biopsies from 8 patients with GCA, 2 from patients with TAK, 6 from patients with FIA, and 15 from patients without vasculitis, who had non-inflammatory aneurysms. Eleven temporal artery biopsies were collected from 5 patients with GCA and 6 controls. The presence of VZV was not identified in either the specimens from patients with large vessel vasculitis or from the controls. Conclusions: Using surgically sterile snap-frozen specimens, we were unable to confirm recent reports of the presence of VZV in either aortas or temporal arteries from patients with large vessel vasculitis or controls.

We aimed to detect changes in magnetic resonance sialography (MRS) of HCV patients with and without vasculitis. We studied 32 HCV patients (19 female, mean age 48.8 ± 10.3 years) and 20 age- and gender-matched healthy controls. Half of the patients had vasculitis. Demographic, clinical and serological data were prospectively evaluated. In patients with vasculitis, the disease activity was assessed by the Birmingham Vasculitis Activity Score (BVAS). MRS was performed on all patients and controls. Abnormal MRS was found in 25% of patients, (6/16 and 2/16 in patients with and without vasculitis, respectively). Among patients with vasculitis, those with abnormal MRS had longer disease duration, higher leukocytic and lymphocytic counts and more frequent cryoglobulinemia (P vasculitis, longer disease duration and cryoglobulinemia were associated with abnormal findings on MRS. To confirm our results, we propose larger-scale, multicentre studies with longer evaluation periods. © 2014 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

  7. Curcumin Prevents Acute Neuroinflammation and Long-Term Memory Impairment Induced by Systemic Lipopolysaccharide in Mice

    Full Text Available Systemic lipopolysaccharide (LPS induces an acute inflammatory response in the central nervous system (CNS (“neuroinflammation” characterized by altered functions of microglial cells, the major resident immune cells of the CNS, and an increased inflammatory profile that can result in long-term neuronal cell damage and severe behavioral and cognitive consequences. Curcumin, a natural compound, exerts CNS anti-inflammatory and neuroprotective functions mainly after chronic treatment. However, its effect after acute treatment has not been well investigated. In the present study, we provide evidence that 50 mg/kg of curcumin, orally administered for 2 consecutive days before a single intraperitoneal injection of a high dose of LPS (5 mg/kg in young adult mice prevents the CNS immune response. Curcumin, able to enter brain tissue in biologically relevant concentrations, reduced acute and transient microglia activation, pro-inflammatory mediator production, and the behavioral symptoms of sickness. In addition, short-term treatment with curcumin, administered at the time of LPS challenge, anticipated the recovery from memory impairments observed 1 month after the inflammatory stimulus, when mice had completely recovered from the acute neuroinflammation. Together, these results suggest that the preventive effect of curcumin in inhibiting the acute effects of neuroinflammation could be of value in reducing the long-term consequences of brain inflammation, including cognitive deficits such as memory dysfunction.

    2018-04-01

    In order to investigate the viral etiology of acute infections of central nervous system (CNS), multiplex and single PCRs combined with serology for arboviruses were applied on samples from 132 hospitalized patients in Greece during May 2014-December 2016. A viral pathogen was detected in 52 of 132 (39.4%) cases with acute CNS infection. Enteroviruses predominated (15/52, 28.8%), followed by West Nile virus (9/52, 17.3%). Phleboviruses, varicella-zoster virus, and Epstein-Barr virus accounted for 15.4%, 13.5%, and 11.5% of the cases, respectively. The study gives an insight into the etiology of viral CNS infections in a Mediterranean country, where arboviruses should be included in the differential diagnosis of acute CNS infections. © 2017 Wiley Periodicals, Inc.

    Granulomatosis with polyangiitis (GPA) is a systemic necrotizing vasculitis that is associated with granulomatous inflammation and the presence of anti-neutrophil cytoplasmic antibodies (ANCAs) directed against proteinase 3 (PR3). We previously determined that PR3 on the surface of apoptotic neutrophils interferes with induction of antiinflammatory mechanisms following phagocytosis of these cells by macrophages. Here, we demonstrate that enzymatically active membrane-associated PR3 on apoptotic cells triggered secretion of inflammatory cytokines, including granulocyte CSF (G-CSF) and chemokines. This response required the IL-1R1/MyD88 signaling pathway and was dependent on the synthesis of NO, as macrophages from animals lacking these pathways did not exhibit a PR3-associated proinflammatory response. The PR3-induced microenvironment facilitated recruitment of inflammatory cells, such as macrophages, plasmacytoid DCs (pDCs), and neutrophils, which were observed in close proximity within granulomatous lesions in the lungs of GPA patients. In different murine models of apoptotic cell injection, the PR3-induced microenvironment instructed pDC-driven Th9/Th2 cell generation. Concomitant injection of anti-PR3 ANCAs with PR3-expressing apoptotic cells induced a Th17 response, revealing a GPA-specific mechanism of immune polarization. Accordingly, circulating CD4+ T cells from GPA patients had a skewed distribution of Th9/Th2/Th17. These results reveal that PR3 disrupts immune silencing associated with clearance of apoptotic neutrophils and provide insight into how PR3 and PR3-targeting ANCAs promote GPA pathophysiology.

    2013-05-01

    Traumatic brain injury (TBI) is a significant biomedical problem among military personnel and civilians. There exists an urgent need to develop and refine biological measures of acute brain injury and chronic recovery after brain injury. Such measures "biomarkers" can assist clinicians in helping to define and refine the recovery process and developing treatment paradigms for the acutely injured to reduce secondary injury processes. Recent biomarker studies in the acute phase of TBI have highlighted the importance and feasibilities of identifying clinically useful biomarkers. However, much less is known about the subacute and chronic phases of TBI. We propose here that for a complex biological problem such as TBI, multiple biomarker types might be needed to harness the wide range of pathological and systemic perturbations following injuries, including acute neuronal death, neuroinflammation, neurodegeneration and neuroregeneration to systemic responses. In terms of biomarker types, they range from brain-specific proteins, microRNA, genetic polymorphism, inflammatory cytokines and autoimmune markers and neuro-endocrine hormones. Furthermore, systems biology-driven biomarkers integration can help present a holistic approach to understanding scenarios and complexity pathways involved in brain injury.

    To compare disease severity classification systems for six-month outcome prediction in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). Patients with newly diagnosed AAV from 53 tertiary institutions were enrolled. Six-month remission, overall survival, and end-stage renal disease (ESRD)-free survival were evaluated. According to the European Vasculitis Study Group (EUVAS)-defined disease severity, the 321 enrolled patients were classified as follows: 14, localized; 71, early systemic; 170, generalized; and 66, severe disease. According to the rapidly progressive glomerulonephritis (RPGN) clinical grading system, the patients were divided as follows: 60, grade I; 178, grade II; 66, grade III; and 12, grade IV. According to the Five-Factor Score (FFS) 2009, 103, 109, and 109 patients had ≤1, 2, and ≥3 points, respectively. No significant difference in remission rates was found in any severity classification. The overall and ESRD-free survival rates significantly differed between grades I/II, III, and IV, regardless of renal involvement. Severe disease was a good predictor of six-month overall and ESRD-free survival. The FFS 2009 was useful to predict six-month ESRD-free survival but not overall survival. The RPGN grading system was more useful to predict six-month overall and ESRD-free survival than the EUVAS-defined severity or FFS 2009.

    Large vessel vasculitis can pose a significant diagnostic challenge. It may be insidious in onset with the only presenting symptoms consisting of constitutional compromise. It may mimic other pathologies and the only serological abnormalities may be abnormal inflammatory markers. Conventional imaging modalities may not be diagnostic. We present a case of large vessel vasculitis that proved a significant diagnostic challenge with diagnosis established on 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) computerised tomography (CT) imaging. This is one of five cases of large vessel vasculitis that were diagnosed in the rheumatology department at our trust over a 12-month period with diagnosis established with the use of 18F-FDG PET CT. We discuss the advantages of 18F-FDG PET CT over more conventional imaging modalities in diagnosing large vessel vasculitis. © Royal College of Physicians 2017. All rights reserved.

    Prophylaxis of the central nervous system in leukemias is a complex problem and there is no optimal solution that is universal for all patients. Radiation therapy, because of its CNS toxicity and potential carcinogenicity, is reserved for those in the highest risk groups. The cranial radiation dose is 18 Gy, while the spinal cord is treated with intrathecal methotrexate or multidrug therapy. The authors describe the basic aspects of radiation therapy treatment planning, as the main areas that should be included in treatment field, in order to guarantee favourable results. (author)

    Eriksson, Charlotta E; Studahl, Marie; Bergström, Tomas

    2016-06-15

    Herpes simplex encephalitis (HSE) is characterized by a pronounced inflammatory activity in the central nervous system (CNS). Here, we investigated the acute and prolonged complement system activity in HSE patients, by using enzyme-linked immunosorbent assays (ELISAs) for numerous complement components (C). We found increased cerebrospinal fluid concentrations of C3a, C3b, C5 and C5a in HSE patients compared with healthy controls. C3a and C5a concentrations remained increased also compared with patient controls. Our results conclude that the complement system is activated in CNS during HSE in the acute phase, and interestingly also in later stages supporting previous reports of prolonged inflammation.

    Acute pancreatitis has a highly variable course. Currently there is no widely accepted method to measure disease activity in patients hospitalized for acute pancreatitis. We aimed to develop a clinical activity index that incorporates routine clinical parameters to assist in the measurement, study, and management of acute pancreatitis. We used the UCLA/RAND appropriateness method to identify items for inclusion in the disease activity instrument. We conducted a systematic literature review followed by two sets of iterative modified Delphi meetings including a panel of international experts between November 2014 and November 2015. The final instrument was then applied to patient data obtained from five separate study cohorts across Southern California to assess profiles of disease activity. From a list of 35 items comprising 6 domains, we identified 5 parameters for inclusion in the final weighted clinical activity scoring system: organ failure, systemic inflammatory response syndrome, abdominal pain, requirement for opiates and ability to tolerate oral intake. We applied the weighted scoring system across the 5 study cohorts comprising 3,123 patients. We identified several distinct patterns of disease activity: (i) overall there was an elevated score at baseline relative to discharge across all study cohorts, (ii) there were distinct patterns of disease activity related to duration of illness as well as (iii) early and persistent elevation of disease activity among patients with severe acute pancreatitis defined as persistent organ failure. We present the development and initial validation of a clinical activity score for real-time assessment of disease activity in patients with acute pancreatitis.

    Highlights: • Three different MRI grading and classification systems for acute hamstring injuries are overall reliable. • Reliability for the subcategories within these MRI grading and classification systems remains, however, unclear. - Abstract: Objective: To assess and compare the intra- and interrater reliability of three different MRI grading and classification systems after acute hamstring injury. Methods: Male athletes (n = 40) with clinical diagnosis of acute hamstring injury and MRI ≤5 days were selected from a prospective cohort. Two radiologists independently evaluated the MRIs using standardised scoring form including the modified Peetrons grading system, the Chan acute muscle strain injury classification and the British Athletics Muscle Injury Classification. Intra-and interrater reliability was assessed with linear weighted kappa (κ) or unweighted Cohen's κ and percentage agreement was calculated. Results: We observed ‘substantial’ to ‘almost perfect’ intra- (κ range 0.65–1.00) and interrater reliability (κ range 0.77–1.00) with percentage agreement 83–100% and 88–100%, respectively, for severity gradings, overall anatomical sites and overall classifications for the three MRI systems. We observed substantial variability (κ range −0.05 to 1.00) for subcategories within the Chan classification and the British Athletics Muscle Injury Classification, however, the prevalence of positive scorings was low for some subcategories. Conclusions: The modified Peetrons grading system, overall Chan classification and overall British Athletics Muscle Injury Classification demonstrated ‘substantial' to ‘almost perfect' intra- and interrater reliability when scored by experienced radiologists. The intra- and interrater reliability for the anatomical subcategories within the classifications remains unclear.

    Bogman, M.J.; Cornelissen, I.M.; Koene, R.A.

    1984-01-01

    In immunosuppressed mice that carry rat skin xeno-grafts, acute antibody-mediated graft rejection (AAR) can be induced by intravenous administration of mouse anti-rat globulin. Dependent on the amount of antibody injected and on the complement status of the recipient, an Arthus-like or a Shwartzman-like pattern of vasculitis occurs. The role of polymorphonuclear granulocytes (PMNs) in either type of vasculitis was tested by inducing AAR in recipients depleted of PMNs by total body irradiation. Despite the absence of PMNs in the graft vessels, AAR occurred both in the Arthus-like and in the Shwartzman-like type. Moreover, AAR could be elicited in PMN-depleted recipients that were complement-depleted by cobra venom factor treatment or were congenitally C5-deficient. We conclude that neither the PMN nor complement is an essential mediator the PMN nor complement is an essential mediator in this form of antibody-mediated vasculitis

    With the recent rise in obesity awareness and the increased understanding of the importance of physical activity in promoting overall health, greater emphasis has been placed on improving physical fitness to enhance quality of life. Surya Namaskar, a component of Hatha Yoga, has been practiced by Asian Indians for hundreds of years and is often used in place of a typical fitness program. It consists of a series of postures (asanas) that are repeated 12 times per round. Only one published study has looked specifically at Surya Namaskar, measuring the energy cost of individual asanas (Sinha et al., 2004). However, practitioners typically perform several rounds of the asanas during a session. To assess the cardiorespiratory and metabolic responses of four rounds of Surya Namaskar, a typical amount performed by practitioners, to determine its potential as a training and weight loss tool. Six healthy Asian Indian men and women (18-22 years) who had trained in Surya Namaskar for over two years participated in the study. Testing was completed in a single session lasting about 30 min. To measure heart rate and oxygen consumption while performing the four rounds, participants were connected to a heart rate monitor and the Oxycon Mobile Metabolic System. Participants exercised at 80% of age-predicted maximal heart rate (HRmax) during Round 2, 84% during Round 3, and 90% during Round 4. Average intensity during the four rounds was 80% HRmax, sufficient to elicit a cardiorespiratory training effect. Oxygen consumption averaged 26 ml/kg/min during each round, resulting in an energy expenditure of 230 kcals during a 30 min session for a 60 kg individual. Regular practice of Surya Namaskar may maintain or improve cardiorespiratory fitness, as well as promote weight management. Copyright © 2010 Elsevier Ltd. All rights reserved.

    During the past three decades, improvements in the treatment of childhood leukemia have resulted in high cure rates, particularly for acute lymphoblastic leukemia (ALL). Unfortunately, successful therapy has come with a price, as significant morbidity can result from neurological affects which harm the brain and spinal cord. The expectation and hope is that chemotherapy, as a primary means of CNS therapy, will result in acceptable disease control with less CNS morbidity than has been observed with combinations of chemotherapy and radiotherapy over the past several decades. In this review we discuss the poignant, historical aspects of CNS leukemia therapy, outline current methods of systemic and CNS leukemia therapy, and present imaging findings we have encountered in childhood leukemia patients with a variety of acute neurological conditions. A major objective of our research is to understand the neuroimaging correlates of acute and chronic effects of cancer and therapy. Specific features related to CNS leukemia and associated short-term toxicities, both disease- and therapy-related, are emphasized in this review with the specific neuroimaging findings. Specific CNS findings are similarly important when treating acute myelogenous leukemia (AML), and details of leukemic involvement and toxicities are also presented in this entity. Despite contemporary treatment approaches which favor the use of chemotherapy (including intrathecal therapy) over radiotherapy in the treatment of CNS leukemia, children still occasionally experience morbid neurotoxicity. Standard neuroimaging is sufficient to identify a variety of neurotoxic sequelae in children, and often suggest specific etiologies.

    To assess and compare the intra- and interrater reliability of three different MRI grading and classification systems after acute hamstring injury. Male athletes (n=40) with clinical diagnosis of acute hamstring injury and MRI ≤5days were selected from a prospective cohort. Two radiologists independently evaluated the MRIs using standardised scoring form including the modified Peetrons grading system, the Chan acute muscle strain injury classification and the British Athletics Muscle Injury Classification. Intra-and interrater reliability was assessed with linear weighted kappa (κ) or unweighted Cohen's κ and percentage agreement was calculated. We observed 'substantial' to 'almost perfect' intra- (κ range 0.65-1.00) and interrater reliability (κ range 0.77-1.00) with percentage agreement 83-100% and 88-100%, respectively, for severity gradings, overall anatomical sites and overall classifications for the three MRI systems. We observed substantial variability (κ range -0.05 to 1.00) for subcategories within the Chan classification and the British Athletics Muscle Injury Classification, however, the prevalence of positive scorings was low for some subcategories. The modified Peetrons grading system, overall Chan classification and overall British Athletics Muscle Injury Classification demonstrated 'substantial' to 'almost perfect' intra- and interrater reliability when scored by experienced radiologists. The intra- and interrater reliability for the anatomical subcategories within the classifications remains unclear. Copyright © 2017 Elsevier B.V. All rights reserved.

  18. Vasculitis assessment with [18F]F.D.G. positron emission tomography

    International Nuclear Information System (INIS)

    Liozon, E.; Monteil, J.

    2008-01-01

    [ 18 F]fluorodeoxyglucose ( 18 F.D.G.) positron emission tomography (PET) is a noninvasive metabolic imaging modality that is well suited to the assessment of activity and extent of large vessel vasculitis, such as giant cell arteritis and Takayasu arteritis. PET could be more effective than magnetic resonance imaging in detecting the earliest stages of vascular wall inflammation. The visual grading of vascular [ 18 F]F.D.G. uptake makes it possible to discriminate arteritis from atherosclerosis, providing therefore high specificity. High sensitivity can be achieved provided scanning is performed during active inflammatory phase, preferably before starting corticosteroid treatment. Large scale prospective studies are needed to determine the exact value of PET imaging in assessing the large vessel vasculitis outcome and response to immunosuppressive treatment

    Thirteen consecutive patients with subacute unilateral loss of vision and periorbital pain but without pathology of the fundus or increased erythrocyte sedimentation rate, were investigated with visual evoked response, electrophoresis of serum and cerebrospinal fluid, and orbital phlebography. Seven of these patients were found to suffer from multiple sclerosis. The remaining 6 were considered to have venous vasculitis. There was a spontaneous recovery from visual impairment in all patients with multiple sclerosis, but not in patients with venous vasculitis. Of the latter patients, only two, who were treated with steroids within the first four days after onset of symptoms, regained vision. It appears that orbital phlebography is the diagnostic procedure of choice for proper management of patients with subacute loss of vision. (orig.)

    Hydroxyurea is used in essential thrombocythaemia to lower thromboembolic risk. Cutaneous adverse effects from hydroxyurea are diverse. Small vessel vasculitis has been rarely reported, and the coexistence of several different morphologies has not been described. We report a case of acral keratoses, psoriasiform plaques and leucocytoclastic vasculitis (LCV) in a patient with essential thrombocythaemia. A 69-year-old woman developed a confusing array of skin lesions including keratotic papules, psoriasiform plaques and keratoderma 4 years after commencing hydroxyurea therapy. The initial diagnosis was hand and foot psoriasis, but lesions were resistant to therapy. With an increase in the dose of hydroxyurea, the lesions ulcerated. Skin biopsies taken from different sites indicated different diagnoses, including LCV. Discontinuation of hydroxyurea yielded rapid improvement. Although the most commonly reported cutaneous adverse effect from hydroxyurea is leg ulceration, this can be preceded or accompanied by less dramatic skin lesions. Unless recognized, delayed diagnosis and lesion progression can occur. © 2015 British Association of Dermatologists.

  1. Recommendations of the Brazilian Society of Rheumatology for the induction therapy of ANCA-associated vasculitis

    Full Text Available Abstract The purpose of these recommendations is to guide the appropriate induction treatment of antineutrophil cytoplasmic antibody-associated vasculitis (AAV patients with active disease. The recommendations proposed by the Vasculopathies Committee of the Brazilian Society Rheumatology for induction therapy of AAV, including granulomatosis with polyangiitis, microscopic polyangiitis and renal-limited vasculitis, were based on systematic literature review and expert opinion. Literature review was performed using Medline (PubMed, EMBASE and Cochrane database to retrieve articles until October 2016. PRISMA guidelines were used for the systematic review and articles were assessed according to the Oxford levels of evidence. Sixteen recommendations were made regarding different aspects of induction therapy for AAV. The purpose of these recommendations is to serve as a guide for therapeutic decisions by health care professionals in the management of AAV patients presenting active disease.

    Giant cell arteritis and Takayasu arteritis are the two major forms of idiopathic large vessel vasculitis. High doses of glucocorticoids are effective in inducing remission in both conditions, but relapses and recurrences are common, requiring prolonged glucocorticoid treatment with the risk of the related adverse events. Areas covered: In this article, we will review the standard and biological treatment strategies in large vessel vasculitis, and we will focus on the current approaches to these diseases. Expert commentary: The results of treatment trials with conventional immunosuppressive agents such as methotrexate, azathioprine, mycophenolate mofetil, and cyclophosphamide have overall been disappointing. TNF-α blockers are ineffective in giant cell arteritis, while observational evidence and a phase 2 randomized trial support the use of tocilizumab in relapsing giant cell arteritis. Observational evidence strongly supports the use of anti-TNF-α agents and tocilizumab in Takayasu patients with relapsing disease. However biological agents are not curative, and relapses remain common.

    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. At times, this can affect the vascular endothelium, giving rise to vasculitic manifestations, although there are few reports in the literature of its role in the presentation of HIV.

    Churg-Strauss Syndrome (CSS) is a rare vasculitis with multiorgan involvement. Cardiac manifestations are common causing serious complications. We report a case of CSS masquerading as a non-ST elevation myocardial infarction with heart failure. CSS should be considered in the differential diagnosis of an acute coronary syndrome(ACS)with normal coronary arteries when history of asthma, peripheral eosinophilia and multisystemic involvement is present.

    The accurate assessment and communication of the severity of acute allergic reactions is important to patients, clinicians, researchers, the food industry, public health and regulatory authorities. Severity has different meanings to different stakeholders with patients and clinicians rating...... of different stakeholder groups. We propose a novel approach to develop and then validate a harmonized scoring system for acute allergic reactions, based on a data-driven method that is informed by clinical and patient experience and other stakeholders' perspectives. We envisage two formats: (i) a numerical...... the significance of particular symptoms very differently. Many severity scoring systems have been generated, most focusing on the severity of reactions following exposure to a limited group of allergens. They are heterogeneous in format, none has used an accepted developmental approach and none has been validated...

  8. Prolonged Survival of Acute Lymphoblastic Leukemia with Intrathecal Treatments for Isolated Central Nervous System Relapse

    Directory of Open Access Journals (Sweden)

    Elan Gorshein

    2018-01-01

    Full Text Available Acute lymphoblastic leukemia is commonly cured when diagnosed in the pediatric population. It portends a poorer prognosis if present in adult patients. Although adults frequently achieve complete remission, relapse rates are substantial, particularly among the elderly and high-risk populations. In the absence of prophylactic intrathecal chemotherapy, more than half of patients may develop CNS involvement or relapse, which is associated with significant risk for systemic illness. This report describes a patient with acute lymphoblastic leukemia with repeated isolated CNS relapses. This case should remind clinicians that isolated CNS disease in the absence of systemic recurrence could successfully respond to intrathecal therapy and offer patients a favorable quality of life.

    Objective To analyse the differences between patients with granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (MPA) entered into randomised clinical trials (RCTs) and those followed in large observational cohorts. Methods The main characteristics and outcomes of patients with generalised and/or severe GPA or MPA with a five-factor score ≥1 enrolled in the French Vasculitis Study Group (FVSG) or the US-Canadian-based Vasculitis Clinical Research Consortium cohorts were compared to those enrolled in one of 2 FVSG clinical RCTs (WEG91, WEGENT) or 3 European Vasculitis Society clinical trials (CYCLOPS, CYCAZAREM, IMPROVE). Results 657 patients (65.3% with GPA) in RCTs were compared to 437 in cohorts (90.6% with GPA). RCT patients were older at diagnosis than the cohort patients (56.6±13.9 vs. 46.8±17.3 years), had higher Birmingham vasculitis activity score (19.5±9.1 vs. 16.9±7.4), and more frequent kidney disease (84.0% vs. 54.9%) but fewer ear, nose, and throat symptoms (56.8% vs. 72.2%). At 56 months post-diagnosis, mortality and relapse rates, adjusted for age and renal function, were higher for patients with GPA in RCTs vs. cohorts (10.7% vs. 2.5% [p=0.001] and 22.5% vs. 15.6% [p=0.03], respectively) but similar for patients with MPA (6.2% vs. 6.6% [p=0.92] and 16.6% vs. 10.1% [p=0.39], respectively). Conclusion Patients with GPA or MPA in RCTs and those in observational cohorts show important differences that should be remembered when interpreting results based on these study populations.

    Background and objectives ANCA-associated vasculitis is commonly found in elderly patients, but there are few data concerning outcome and treatment in the highest age groups. Design, setting, participants, & measurements Consecutive patients (N=151) presenting between 1997 and 2009 were retrospectively included from local registries in six centers in Sweden, the United Kingdom, and the Czech Republic if diagnosed with microscopic polyangiitis or granulomatosis with polyangiitis at age ≥75 years during the study period. Patients were followed until 2 years from diagnosis or death. Data on survival and renal function were analyzed with respect to age, sex, ANCA specificity, renal function, C-reactive protein, comorbidities, and Birmingham Vasculitis Activity Score at diagnosis as well as treatment during the first month. Results Median follow-up was 730 days (interquartile range, 244–730). Overall 1-year survival was 71.5% and 2-year survival was 64.6%. Older age, higher creatinine, and lower Birmingham Vasculitis Activity Score were associated with higher mortality in multivariable analysis. Patients who were not treated with standard immunosuppressive therapy had significantly worse survival. Renal survival was 74.8% at 1 year. No new cases of ESRD occurred during the second year. High creatinine at diagnosis was the only significant predictor of renal survival in multivariable analysis. Conclusions ANCA-associated vasculitis is a disease with substantial mortality and morbidity among elderly patients. This study showed a better prognosis for those who received immunosuppressive treatment and those who were diagnosed before having developed advanced renal insufficiency. PMID:26100457

    The 2012 International Chapel Hill Consensus Conference on the Nomenclature of Vasculitides defined drug-associated immune complex vasculitis as a distinct entity included within the category of vasculitis associated with probable etiology. In the present study we assessed the clinical spectrum of patients with drug-associated cutaneous vasculitis (DACV). Case records were reviewed of patients with DACV treated at a tertiary referral hospital over a 36-year period. A diagnosis of DACV was considered if the drug was taken within a week before the onset of the disease. From a series of 773 unselected cutaneous vasculitis cases, 239 patients (30.9%; 133 men and 106 women; mean age 36 yrs) were diagnosed with DACV. Antibiotics (n=149; 62.3%), mainly β-lactams and nonsteroidal antiinflammatory drugs (NSAID; n=24; 10%) were the most common drugs. Besides skin lesions (100%), the most common clinical features were joint (51%) and gastrointestinal (38.1%) manifestations, nephropathy (34.7%), and fever (23.8%). The most remarkable laboratory data were increased erythrocyte sedimentation rate (40.2%), presence of serum cryoglobulins (26%), leukocytosis (24.7%), positive antinuclear antibodies (21.1%), anemia (18.8%), and positive rheumatoid factor (17.5%). Despite drug discontinuation and bed rest, 108 patients (45.2%) required medical treatment, mainly corticosteroids (n=71) or immunosuppressive drugs (n=7). After a median followup of 5 months, relapses occurred in 18.4% of patients, and persistent microhematuria or renal insufficiency in 3.3% and 5%, respectively. DACV is generally associated with antibiotics and NSAID. In most cases it has a favorable prognosis, although a small percentage of patients may develop residual renal damage.

    Several studies have demonstrated the crucial role of complement activation in the pathogenesis of ANCA-associated vasculitis. We aimed to assess the association between baseline serum C3 (sC3) levels and long-term outcomes in patients with renal vasculitis. This retrospective study included 111 patients with renal vasculitis from three hospitals who underwent a renal biopsy between 1997 and 2014. Serum levels of C3 were measured at the onset and the study population was divided into three tertiles according to sC3 concentrations (tertile 1 128 mg/dl). Patients with lower sC3 (tertile 1) were compared with those having higher levels of sC3 (tertile 2 and tertile 3). Histological, clinical, and laboratory data were recorded for analysis. The primary end point was the composite of end-stage renal disease (ESRD) and death from any cause. Lower sC3 levels were associated with a higher need for dialysis and lower response rate to treatment (p = 0.04 and p = 0.007, respectively). Renal and global survival at 1 and 5 years was 53 and 46 % in patients with lower sC3 (tertile 1) compared with 72 and 65 % in patients with higher sC3 (upper two tertiles) (p = 0.04). In a multivariate Cox-regression model, when adjusted by renal function and histopatholologic categories, lower sC3 remained as an independent predictor of ESRD and death (HR, 1.9; 95 % CI, 1.1 to 3.4; p = 0.02). Baseline serum C3 levels have an independent prognostic value in predicting long-term renal and global survival in patients with renal vasculitis.

    2010-01-01

    This paper presents the first conceptual study into creating a Plantae-inspired vascular network within a fibre-reinforced polymer composite laminate, which provides an ongoing self-healing functionality without incurring a mass penalty. Through the application of a ‘lost-wax’ technique, orthogonal hollow vascules, inspired by the ‘ray cell’ structures found in ring porous hardwoods, were successfully introduced within a carbon fibre-reinforced epoxy polymer composite laminate. The influence on fibre architecture and mechanical behaviour of single vascules (located on the laminate centreline) when aligned parallel and transverse to the local host ply was characterized experimentally using a compression-after-impact test methodology. Ultrasonic C-scanning and high-resolution micro-CT X-ray was undertaken to identify the influence of and interaction between the internal vasculature and impact damage. The results clearly show that damage morphology is influenced by vascule orientation and that a 10 J low-velocity impact damage event is sufficient to breach the vasculature; a prerequisite for any subsequent self-healing function. The residual compressive strength after a 10 J impact was found to be dependent upon vascule orientation. In general, residual compressive strength decreased to 70 per cent of undamaged strength when vasculature was aligned parallel to the local host ply and a value of 63 per cent when aligned transverse. This bioinspired engineering study has illustrated the potential that a vasculature concept has to offer in terms of providing a self-healing function with minimum mass penalty, without initiating premature failure within a composite structure.

    Radiation accidents or terrorist attacks can result in serious consequences for the civilian population and for military personnel responding to such emergencies. The early medical management situation requires quantitative indications for early initiation of cytokine therapy in individuals exposed to life-threatening radiation doses and effective triage tools for first responders in mass-casualty radiological incidents. Previously established animal (Mus musculus, Macaca mulatta) total-body irradiation (γ-exposure) models have evaluated a panel of radiation-responsive proteins that, together with peripheral blood cell counts, create a multiparametic dose-predictive algorithm with a threshold for detection of ~1 Gy from 1 to 7 d after exposure as well as demonstrate the acute radiation syndrome severity score systems created similar to the Medical Treatment Protocols for Radiation Accident Victims developed by Fliedner and colleagues. The authors present a further demonstration of the acute radiation sickness severity score system in a mouse (CD2F1, males) TBI model (1-14 Gy, Co γ-rays at 0.6 Gy min) based on multiple biodosimetric endpoints. This includes the acute radiation sickness severity Observational Grading System, survival rate, weight changes, temperature, peripheral blood cell counts and radiation-responsive protein expression profile: Flt-3 ligand, interleukin 6, granulocyte-colony stimulating factor, thrombopoietin, erythropoietin, and serum amyloid A. Results show that use of the multiple-parameter severity score system facilitates identification of animals requiring enhanced monitoring after irradiation and that proteomics are a complementary approach to conventional biodosimetry for early assessment of radiation exposure, enhancing accuracy and discrimination index for acute radiation sickness response categories and early prediction of outcome.

    It is controversial whether microorganisms play a role in the pathogenesis of large and medium vessel vasculitides (eg, giant cell arteritis [GCA], Takayasu arteritis [TAK] and focal idiopathic aortitis [FIA]). Recent studies have reported the presence of Varicella Zoster Virus (VZV) within formalin-fixed, paraffin-embedded temporal arteries and aortas of about three-quarters or more of patients with these conditions, and in a minority of controls. In a prospective study, we sought to confirm these findings using DNA extracted from vessels that were harvested under surgically aseptic conditions and snap frozen. DNA samples extracted from 11 surgically sterile temporal arteries and 31 surgically sterile thoracic aortas were used in an attempt to identify the vessel-associated VZV genome. Two different validated PCR methods were used. Thirty-one thoracic aorta aneurysm specimens included biopsies from 8 patients with GCA, 2 from patients with TAK, 6 from patients with FIA, and 15 from patients without vasculitis, who had non-inflammatory aneurysms. Eleven temporal artery biopsies were collected from 5 patients with GCA and 6 controls. The presence of VZV was not identified in either the specimens from patients with large vessel vasculitis or from the controls. Using surgically sterile snap-frozen specimens, we were unable to confirm recent reports of the presence of VZV in either aortas or temporal arteries from patients with large vessel vasculitis or controls.

    Technology advances continue to impact patient care and physician workflow. To enable more efficient performance of billing activities, a point-of-care (POC) handheld computer technology replaced a paper-based system on an acute pain management service. Using a handheld personal digital assistant (PDA) and software from MDeverywhere (MDe, MDeverywhere, Long Island, NY), we performed a 1-yr prospective observational study of an anesthesiology acute pain management service billings and collections. Seventeen anesthesiologists providing billable acute pain services were trained and entered their charges on a PDA. Twelve months of data, just before electronic implementation (pre-elec), were compared to a 12-m period after implementation (post-elec). The total charges were 4883 for 890 patients pre-elec and 5368 for 1128 patients post-elec. With adoption of handheld billing, the charge lag days decreased from 29.3 to 7.0 (P billing using PDAs to replace a paper-based billing system improved the collection rate and decreased the number of charge lag days with a positive return on investment. The handheld PDA billing system provided POC support for physicians during their daily clinical (e.g., patient locations, rounding lists) and billing activities, improving workflow.

    Kawasaki disease (KD) is a systemic vasculitis frequent in children younger than 5 years of age. It involves coronary arteries and other medium-sized vessels. There also exists evidence of inflammatory and proliferative changes affecting the biliary tract and lymphocyte infiltration of the renal interstitial. We describe the case of a 9-year-old girl who developed high-grade fever, bilateral non-purulent conjunctivitis, «strawberry» tongue, desquamation of the fingers and toes, cholestatic syndrome, edema and elevated serum creatinine. KD is a diagnostic challenge for the pediatrician. In every patient with high-grade fever, cholestasis and acute kidney injury, KD should be included in the differential diagnosis, even though more research is necessary to evaluate this atypical association.

    2011-09-01

    Full Text Available Objective: Hypereosinophilic syndromes are a heterogeneous group of uncommon disorders characterized by the presence of marked peripheral blood eosinophilia, tissue eosinophilia, or both, resulting in a wide variety of clinical manifestations, often without an identifiable cause. Churg-Strauss syndrome is a systemic vasculitis characterized by prominent peripheral eosinophilia, asthma and systemic involvement. The presence of mild to severe eosinophilia and systemic involvement raise the search of many trigger factor that need to be ruled out. Distinguishing CSS from idiopathic hypereosinophilic syndrome may be particularly challenging, especially in ANCA negative patients. Methods: The aim of the present study was to present a small case series of patients referred to a Rheumatology Unit for mild to severe eosinophilia and signs and symptoms of systemic involvement and to outline the clinical significance of molecular biology in the work-up of hypereosinophilia. Results: Eleven patients with moderate to severe peripheral eosinophylia, were referred to our Unit from 1996 to 2007. Female to male ratio was 7/4, mean age 40.54 (range 22-75. Three out of eleven patients resulted positive for molecular biology. The diagnosis of idiopathic hypereosinophylia was confirmed in one out of three on the basis of the clinical picture and bone marrow biopsy. Conclusions: Molecular biology may be useful in the screening and in the follow-up of a new hypereosinophylic patient.

    Purpose: To determine the acute and chronic toxic effects of radiotherapy in patients with systemic lupus erythematosus (SLE). Methods and Materials: Medical records of 21 consecutive patients with SLE, who had received 34 courses of external beam radiotherapy and one low-dose-rate prostate implant, were retrospectively reviewed. Patients with discoid lupus erythematosus were excluded. Results: Median survival was 2.3 years and median follow-up 5.6 years. Eight (42%) of 19 patients evaluable for acute toxicity during radiotherapy experienced acute toxicity of Grade 1 or greater, and 4 (21%) had acute toxicity of Grade 3 or greater. The 5- and 10-year incidence of chronic toxicity of Grade 1 or greater was 45% (95% confidence interval [CI], 22-72%) and 56% (95% CI, 28-81%), respectively. The 5- and 10-year incidence of chronic toxicity of Grade 3 or greater was 28% (95% CI, 18-60%) and 40% (95% CI, 16-72%), respectively. Univariate analysis showed that chronic toxicity of Grade 1 or greater correlated with SLE renal involvement (p < 0.006) and possibly with the presence of five or more American Rheumatism Association criteria (p < 0.053). Chronic toxicity of Grade 3 or greater correlated with an absence of photosensitivity (p < 0.02), absence of arthritis (p < 0.03), and presence of a malar rash (p < 0.04). Conclusions: The risk of acute and chronic toxicity in patients with SLE who received radiotherapy was moderate but was not prohibitive of the use of radiotherapy. Patients with more advanced SLE may be at increased risk for chronic toxicity

    Implementing integrated systems for emergency care of patients with acute ischemic stroke helps reduce morbidity and mortality. We describe the process of organizing and implementing a regional system to cover around 3.7 million people and its main initial results. We performed a descriptive analysis of the implementation process and a retrospective analysis of the following parameters: number of patients prenotified by the pre-hospital system; number of times thrombolysis was performed; door-to-needle time; and functional assessment three months after stroke. The implementation process started in November 2005 and ended in December 2009, and included 11 health centers. There were 3574 prenotifications from the prehospital system. Thrombolysis was performed in 1142 patients. The percentage of patients receiving thrombolysis rose during the study period, with a maximum of 16%. Median door-to-needle time was 62 min in 2009. Functional recovery three months after stroke was total or near total in 50% of patients. The regional system implemented for emergency care of patients with acute ischemic stroke has led to health gains, with progressive improvements in patients' access to thrombolysis, and to greater equity in the health care system, thus helping to reduce mortality from cerebrovascular disease in Portugal. Our results, which are comparable with those of international studies, support the strategy adopted for implementation of this system. Copyright © 2013 Sociedade Portuguesa de Cardiologia.

    The aim of this study was to evaluate the feasibility of hybrid [ 18 F]fluorodeoxyglucose (FDG) positron emission tomography (PET)/MRI in patients with large vessel vasculitis (LVV) by comparing visual and quantitative parameters to that of PET/CT. Furthermore, the value of PET/MRI in disease activity and extent of LVV was assessed. A total of 16 [ 18 F]FDG PET/MRI and 12 [ 18 F]-FDG PET/CT examinations were performed in 12 patients with LVV. MRI of the vessel wall by T1-weighted and T2-weighted sequences was used for anatomical localization of FDG uptake and identification of morphological changes associated with LVV. In addition, contrast-enhanced (CE) magnetic resonance angiography (MRA) was performed. The vascular FDG uptake in the vasculitis group was compared to a reference group of 16 patients using a four-point visual score. Visual scores and quantitative parameters [maximum standardized uptake value (SUV max ) and target to background ratio (TBR)] were compared between PET/MRI and PET/CT. Furthermore, correlations between C-reactive protein (CRP) and quantitative PET results, as well the extent of vasculitis in PET, MRI/CE-MRA and combined PET/MRI, were analysed. TBRs, SUV max values and visual scores correlated well between PET/MRI and PET/CT (r = 0.92, r = 0.91; r = 0.84, p < 0.05). There was no significant difference between both modalities concerning SUV max measurements and visual scores. In PET/MRI, PET alone revealed abnormal FDG uptake in 86 vascular regions. MRI/CE-MRA indicated 49 vessel segments with morphological changes related to vasculitis, leading to a total number of 95 vasculitis regions in combination with PET. Strong and significant correlations between CRP and disease extent in PET alone (r = 0.75, p = 0.0067) and PET/MRI (r = 0.92, p < 0.0001) in contrast to MRI/CE-MRA only were observed. Regarding disease activity, no significant correlations were seen between quantitative PET results and CRP, although there was a trend towards

    The purpose of this study was to examine whether the monocyte chemoattractant protein-1 (MCP-1) promoter -2518 A/G polymorphism (rs1024611) is associated with susceptibility to vasculitis, rheumatoid arthritis (RA), or multiple sclerosis (MS). A meta-analysis was conducted on the association between the MCP-1 -2518 A/G polymorphism and vasculitis, RA, and MS. Fourteen studies from 13 articles, including six on vasculitis, five on RA, and three on MS, consisting of 3,038 patients and 3,545 controls were available for the meta-analysis. The meta-analysis revealed no association between the MCP-1 -2518 G allele and vasculitis (odds ratio [OR] = 0.990, 95% confidence interval [CI] = 0.749-1.309, p = 0.943). Stratification by ethnicity indicated no association between the G allele of the MCP-1 -2518 A/G polymorphism and vasculitis in Asians and Caucasians. Meta-analysis by vasculitis type revealed an association between the GG+GA genotype of the MCP-1 -2518 A/G polymorphism and Behçet's disease (BD; OR = 1.349, 95% CI = 1.013-1.796, p = 0.040). However, sensitivity analysis showed that the association was not statistically significant after removing a study that was conducted in China (OR = 1.030, 95% CI = 0.667-1.590, p = 0.895), which indicated that the association was not statistically robust. The meta-analysis revealed no association between the MCP-1 -2518 G allele and RA (OR = 0.986, 95% CI = 0.890-1.093, p = 0.793) or MS (OR = 1.281, 95% CI = 0.802-2.046, p = 0.301). Our meta-analysis demonstrates that the MCP-1 -2518 A/G polymorphism is not associated with susceptibility to vasculitis, RA, or MS.

    Introduction Following two decades of armed conflict in Liberia, over 95% of health care facilities were partially or completely destroyed. Although the Liberian health system has undergone significant rehabilitation, one particular weakness is the lack of organized systems for referral and prehospital care. Acute care referral systems are a critical component of effective health care delivery and have led to improved quality of care and patient outcomes. Problem This study aimed to characterize the referral and transfer systems in the largest county of Liberia. A cross-sectional, health referral survey of a representative sample of health facilities in Montserrado County, Liberia was performed. A systematic random sample of all primary health care (PHC) clinics, fraction proportional to district population size, and all secondary and tertiary health facilities were included in the study sample. Collected data included baseline information about the health facility, patient flow, and qualitative and quantitative data regarding referral practices. A total of 62 health facilities-41 PHC clinics, 11 health centers (HCs), and 10 referral hospitals (RHs)-were surveyed during the 6-week study period. In sum, three percent of patients were referred to a higher-level of care. Communication between health facilities was largely unsystematic, with lack of specific protocols (n=3; 5.0%) and standardized documentation (n=26; 44.0%) for referral. While most health facilities reported walking as the primary means by which patients presented to initial health facilities (n=50; 81.0%), private vehicles, including commercial taxis (n=37; 60.0%), were the primary transport mechanism for referral of patients between health facilities. This study identified several weaknesses in acute care referral systems in Liberia, including lack of systematic care protocols for transfer, documentation, communication, and transport. However, several informal, well-functioning mechanisms for

    Full Text Available Aim: To study the impact of Renin-Angiotensin system blockade in experimental acute pyelonephritis, induced by a novel surgical approach via dorsal lumbotomy incision. Materials and Methods : 45 Adult female WISTAR rats aged 8-12 weeks, underwent direct inoculation of 0.1 ml of E.coli suspension into the parenchyma of the surgically exposed kidney. 3 groups of rats were studied: Group A - treated with antibiotics only; Group B- Captopril and antibiotics and Group C- Losartan and antibiotics. Changes of acute inflammation, parenchymal destruction and scarring were compared between the groups on histopathological sections. Kruskal-Wallis test was used for statistical analysis. Results : Changes consistent with acute pyelonephritis were seen in all the kidneys. Mean% scar area in Group A, Group B and Group C was 37.08±1.79, 24.40±1.88 and 24.68±1.32% respectively at end of six weeks. Mean tubular density in Group A, B and C was 17.26±1.92, 47.18±3.00 and 47.00±5.08-tubules/lac mm2 respectively. The differences between the control and the treated animals were significant, though the results did not differ between the losartan and captopril treated rats. Conclusions : Dorsal lumbotomy approach to the kidney provides a good exposure of the kidney. Induction of acute pyelonephritis by direct inoculation of bacteria into renal cortex produced a consistent scar at 6 weeks. Blockade of renin angiotensin system by either captopril or losartan decreased the renal scar area by almost 1/3 at 6 weeks.

    Full Text Available The purpose. To study the factor structure and to establish the associative interaction of pathogenetic links of acute diseases development of the bronchopulmonary system in infants.Materials and methods. The examination group consisted of 59 infants (average age 13.8 ± 1.4 months sick with acute inflammatory bronchopulmonary diseases. Also we tested the level of 25-hydroxyvitamin D (25(ОНD, vitamin D-binding protein, hBPI, cathelicidin LL-37, ß1-defensins, lactoferrin in blood serum with the help of immunoenzymometric analysis. Selection of prognostically important pathogenetic factors of acute bronchopulmonary disease among infants was conducted using ROC-analysis. The procedure for classifying objects was carried out using Hierarchical Cluster Analysis by the method of Centroid-based clustering. Results. Based on the results of the ROC-analysis were selected 15 potential predictors of the development of acute inflammatory diseases of the bronchopulmonary system among infants. The factor analysis made it possible to determine the 6 main components . The biggest influence in the development of the disease was made by "the anemia factor", "the factor of inflammation", "the maternal factor", "the vitamin D supply factor", "the immune factor" and "the phosphorus-calcium exchange factor” with a factor load of more than 0.6. The performed procedure of hierarchical cluster analysis confirmed the initial role of immuno-inflammatory components. The conclusions. The highlighted factors allowed to define a group of parameters, that must be influenced to achieve a maximum effect in carrying out preventive and therapeutic measures. First of all, it is necessary to influence the "the anemia factor" and "the calcium exchange factor", as well as the "the vitamin D supply factor". In other words, to correct vitamin D deficiency and carry out measures aimed at preventing the development of anemia. The prevention and treatment of the pathological course of

    Full Text Available Objective: to reveal the patterns of a change in heart rhythm and breathing in patients with acute systemic injury due to cold in hypothermic and early posthypothermic periods.Subjects and methods. Thirty patients aged 18 to 60 years (3 groups of 10 patients with mild, moderate, and severe cold injury were examined in hypothermic and posthypothermic periods. The patient groups did not differ in gender, age, and weight. Within the first 24 hours after admission, all the patients underwent high-resolution Holter electrocardiographic monitoring that recorded cardiac arrhythmias and breathing disorders.Results. During the therapy performed, as the degree of acute systemic cold injury increased, the patients were found to have a heart rate reduction (from 102 [90; 122] beats/min in Group 1 to 49 [38; 58] beats/min in Group 3 and a circadian index increase (from 105 [88; 125]% in Group 1 to 210 [185; 223]% in Group 3. With increased hypothermia, the victims were detected to have progressive cardiac rhythm and cardiac electrical conduction disturbances, such as supraventricular pacemaker migration, single and paired supraventricular premature beats, paroxysmal atrial tachycardia, atrial fibrillations, and ventricular premature beats. There was decreased heart rhythm variability in all the study groups, to the greatest extent in the patents with severe systemic cold injury. Late ventricular potentials were found in 2 and 7 patients with moderate and severe cold injury, respectively. Breathing disorders were recorded in all the study groups, the greatest increase in the frequency and duration of apnea/hypopnea episodes was noted in the patients with severe hypothermia. A fatal outcome occurred in 4 of the 10 patients with critical hypothermia due to the occurrence of idioventricular rhythm with transition to asystole.Conclusion. Systemic hypothermia is accompanied by cardiac rhythm and cardiac electrical conduction disturbances and respiratory depression

    Full Text Available Abstract Background The activation of the immune system in neurodegeneration has detrimental as well as beneficial effects. Which aspects of this immune response aggravate the neurodegenerative breakdown and which stimulate regeneration remains an open question. To unravel the neuroprotective aspects of the immune system we focused on a model of acute peripheral nerve injury, in which the immune system was shown to be protective. Methods To determine the type of immune response triggered after axotomy of the sciatic nerve, a model for Wallerian degeneration in the peripheral nervous system, we evaluated markers representing the two extremes of a type I and type II immune response (classical vs. alternative using real-time quantitative polymerase chain reaction (RT-qPCR, western blot, and immunohistochemistry. Results Our results showed that acute peripheral nerve injury triggers an anti-inflammatory and immunosuppressive response, rather than a pro-inflammatory response. This was reflected by the complete absence of classical macrophage markers (iNOS, IFNγ, and IL12p40, and the strong up-regulation of tissue repair markers (arginase-1, Ym1, and Trem2. The signal favoring the alternative macrophage environment was induced immediately after nerve damage and appeared to be established within the nerve, well before the infiltration of macrophages. In addition, negative regulators of the innate immune response, as well as the anti-inflammatory cytokine IL-10 were induced. The strict regulation of the immune system dampens the potential tissue damaging effects of an over-activated response. Conclusions We here demonstrate that acute peripheral nerve injury triggers an inherent protective environment by inducing the M2 phenotype of macrophages and the expression of arginase-1. We believe that the M2 phenotype, associated with a sterile inflammatory response and tissue repair, might explain their neuroprotective capacity. As such, shifting the

    Chronic and acute exposure to toxic aerosols belongs to frequent causes of airway diseases. However, asthma attacks due to long-distance inhalative exposure to organic solvents, transmitted via an air condition system, have not been reported so far. The present case illustrates the possibility of air conditioning systems as non-infectious health hazards in occupational medicine. So far, only infectious diseases such as legionella pneumophila pneumonia have commonly been associated to air-conditioning exposures but physicians should be alert to the potential of transmission of toxic volatile substances via air conditioning systems. In view of the events of the 11th of September 2001 with a growing danger of large building terrorism which may even use air conditioning systems to transmit toxins, facility management security staff should be alerted to possible non-infectious toxic health hazards arising from air-conditioning systems.

    Dental pain can have a considerable detrimental effect on an individual's quality of life. Symptomatic apical periodontitis and acute apical abscess are common causes of dental pain and arise from an inflamed or necrotic dental pulp, or infection of the pulpless root canal system. Clinical guidelines recommend that the first-line treatment for teeth with symptomatic apical periodontitis or an acute apical abscess should be removal of the source of inflammation or infection by local, operative measures, and that systemic antibiotics are currently only recommended for situations where there is evidence of spreading infection (cellulitis, lymph node involvement, diffuse swelling) or systemic involvement (fever, malaise). Despite this, there is evidence that dentists continue to prescribe antibiotics for these conditions. There is concern that this could contribute to the development of antibiotic-resistant bacterial colonies both within the individual and within the community as a whole. To evaluate the effects of systemic antibiotics provided with or without surgical intervention (such as extraction, incision and drainage of a swelling or endodontic treatment), with or without analgesics, for symptomatic apical periodontitis or acute apical abscess in adults.

    Full Text Available Background and Objective: Acute and chronic central nervous system (CNS infections are not uncommon in tropical countries and are associated with high morbidity and mortality if specific targeted therapy is not instituted in time. Effects of tubercular meningitis, a form of chronic meningitis on hypothalamic pituitary axis, are well known both at the time of diagnosis and after few months to years of illness. However, there are few reports of pituitary dysfunction in subjects with acute CNS infections. Therefore, this study was aimed at evaluating the pituitary hormonal profile in patients with nonmycobacterial acute meningitis at the time of presentation. Materials and Methods: This prospective case series study included 30 untreated adult patients with acute meningitis, meningoencephalitis, or encephalitis, due to various nonmycobacterial agents, admitted and registered with Lok Nayak Hospital, Maulana Aazd Medical College, New Delhi, between September 2007 and March 2009. Patients with preexisting endocrine diseases, tubercular meningitis and patients on steroids were carefully excluded from the study. The basal pituitary hormonal profile was measured by the electrochemilumniscence technique for serum cortisol, luetinizing hormone (LH, follicular stimulating hormone (FSH, prolactin (PRL, thyrotropin (TSH, free tri-iodothyronine (fT3, and free thyroxine (fT4. Results: The cases (n = 30 comprised of patients with acute pyogenic meningitis (n = 23, viral meningoencephalitis (n = 4, brain abscess (n = 2, and cryptococcal meningitis (n = 1. The mean age of patients was 28.97 ± 11.306 years. Out of 30 patients, 14 (46.7% were males and 16 (58.1% were females. Adrenal insufficiency both absolute and relative was seen in seven (23.3% and hyperprolactinemia was seen in nine (30.0% of the patients. One study subject had central hypothyroidism and seven (23.3 showed low levels of LH and/or FSH. None of patients showed clinical features suggestive of

    Experimental endotoxemia is a translational model to study inflammatory mechanisms involved in the pathophysiology of mood disorders including depression. Disturbed affective cognition constitutes a core aspect in depression, but has never been studied in the context of inflammation. We combined experimental endotoxemia with an established experimental mood induction procedure to assess the interaction between acute inflammation and sad mood and their effects on affective cognition. In this randomized cross-over study, N = 15 healthy males received endotoxin (0.8 ng/kg lipopolysaccharide iv) on one study day and placebo an otherwise identical study day. The affective Go/Nogo task was conducted after experimental induction of neutral and sad mood. Inflammatory markers were assessed hourly. Endotoxin application induced a transient systemic inflammation, characterized by increased leukocyte counts, TNF-alpha and interleukin-6 plasma concentrations (all p sadness ratings, with highest ratings when sad mood was induced during inflammation (p sad vs. neutral mood) × 2 (sad vs. happy Go/Nogo target words) factorial design, we observed a significant target × endotoxin condition interaction (p sad targets during endotoxemia. Additionally, we found a valence × mood interaction (p sad targets in sad mood. In summary, acute inflammation and sad mood are risk factors for disturbed affective cognition. The results may reflect a mood-congruency effect, with prolonged and sustained processing of mood-congruent information during acute inflammation, which may contribute to depression risk.

    Highlights: •Activation of PPARα attenuated LPS-mediated acute lung injury. •Pretreatment with Wy-14643 decreased the levels of IFN-γ and IL-6 in ALI. •Nitrosative stress and lipid peroxidation were downregulated by PPARα activation. •PPARα agonists may be potential therapeutic targets for acute lung injury. -- Abstract: Acute lung injury (ALI) is a major cause of mortality and morbidity worldwide. The activation of peroxisome proliferator-activated receptor-α (PPARα) by its ligands, which include Wy-14643, has been implicated as a potential anti-inflammatory therapy. To address the beneficial efficacy of Wy-14643 for ALI along with systemic inflammation, the in vivo role of PPARα activation was investigated in a mouse model of lipopolysaccharide (LPS)-induced ALI. Using age-matched Ppara-null and wild-type mice, we demonstrate that the activation of PPARα by Wy-14643 attenuated LPS-mediated ALI. This was evidenced histologically by the significant alleviation of inflammatory manifestations and apoptosis observed in the lung tissues of wild-type mice, but not in the corresponding Ppara-null mice. This protective effect probably resulted from the inhibition of LPS-induced increases in pro-inflammatory cytokines and nitroxidative stress levels. These results suggest that the pharmacological activation of PPARα might have a therapeutic effect on LPS-induced ALI

    The main histopathological features in the cutaneous lesions of Churg-Strauss syndrome (CSS) are dermal leukocytoclastic vasculitis with a variable eosinophilic infiltrate and non-vasculitic tissue eosinophilia with granuloma formation. This wide histopathological spectrum may account for the various skin manifestations of CSS. However, the unique histopathological combination of dermal eosinophilic vasculitis and subcutaneous granulomatous phlebitis accompanied by bulla formation has not been previously described. We report an unusual CSS case showing dermal necrotizing eosinophilic vasculitis and granulomatous phlebitis in purpuric lesions coupled with subepidermal blistering. The blisters showed dermal granulomatous dermatitis and eosinophilia without evidence of vasculitis. Dermal necrotizing eosinophilic vasculitis was characterized by fibrinoid alteration of the vessel wall, a prominent perivascular eosinophilic infiltrate, a few infiltrating histiocytes along the affected vessel wall, and the absence of neutrophilic infiltration. The underlying subcutaneous granulomatous phlebitis was characterized by an angiocentric histiocytic infiltrate surrounded by marked eosinophilic infiltrate. Deposition of cytotoxic proteins and radicals derived from eosinophils in the vessel walls and papillary dermis followed by a secondary granulomatous response may account for the unique clinical and histopathological features in this case.

    Full Text Available Abstract Background Acute ischaemic stroke is associated with alteration in systemic markers of vascular function. We measured forearm vascular function (using forearm flow mediated dilatation to clarify whether recent acute ischaemic stroke/TIA is associated with impaired systemic vascular function. Methods Prospective case control study enrolling 17 patients with recent acute ischaemic stroke/TIA and 17 sex matched controls with stroke more than two years previously. Forearm vascular function was measured using flow medicated dilatation (FMD. Results Flow mediated dilatation was 6.0 ± 1.1% in acute stroke/TIA patients and 4.7 ± 1.0% among control subjects (p = 0.18. The mean paired difference in FMD between subjects with recent acute stroke and controls was 1.25% (95% CI -0.65, 3.14; p = 0.18. Endothelium independent dilatation was measured in six pairs of participants and was similar in acute stroke/TIA patients (22.6 ± 4.3% and control subjects (19.1 ± 2.6%; p = 0.43. Conclusions Despite the small size of this study, these data indicate that recent acute stroke is not necessarily associated with a clinically important reduction in FMD.

    Objective: To evaluate the efficacy of systemic glucocorticoid (steroid) combined with high dose inhaled steroid in the treatment of children with acute laryngitis. Methods: A total of 78 children with acute laryngitis were randomly divided into study group( n =40) and control group( n =38) between November 2016 and April 2017. In addition to routine treatment of anti infection and symptomatic treatment, Dexamethasone injection(0.3-0.5 mg/kg, 1-3 d, according to the patient's condition) was provided to each group. In addition to the treatment mentioned above, the study group were assigned to receive 1.0 mg Budesonide suspension for inhalation, oxygen-driven atomizing inhalation, every/30 minutes, 2 times in a row, after that every 12 hours. The improvement of inspiratory dyspnea, hoarseness, barking cough and wheezing of both groups was evaluated at 30 min, 1 h, 2 h, 6 h, 12 h, 24 h and 72 h after treatment.Sigmaplot 11.5 software was used to analyze the data. Results: No significant difference was detected in terms of inspiratory dyspnea, hoarseness, barking cough or stridor score before treatment between the two groups( P >0.05). Compared with those before treatment, symptoms of inspiratory dyspnea, hoarseness, barking cough and stridor score of both groups improved markedly at 12 h and 24 h after treatment( P dyspnea, hoarseness, barking cough or stridor score at each time point after treatment between the two groups( P >0.05). The effective rate was 92.50% and 92.11% in study group and control group, respectively, and no significant difference was noted ( P >0.05). Conclusion: Compared with single systemic glucocorticoid, systemic glucocorticoids combined with inhaled steroid possessed similar efficacy in treating acute laryngitis and relieving laryngeal obstruction of children.

  5. Acute intraperitoneal lipopolysaccharide influences the immune system in the absence of gut dysbiosis.

    There is bidirectional communication between the immune system and the gut microbiome, however the precise mechanisms regulating this crosstalk are not well understood. Microbial-associated molecular patterns (MAMPs) within the gut, including lipopolysaccharide (LPS) that produces a quick and robust activation of the immune system, may be one way by which these interactions occur. Endogenous levels of LPS in the gut are low enough that they do not usually cause disease, although, in times of increased LPS loads, they may be capable of increasing vulnerability of the gut to pathogenic bacteria. Furthermore, chronic, low-grade inflammation can have lasting effects on the gut, but the effects of acute inflammation on gut communities have not been thoroughly assessed. In this study, we first investigated whether a single modest dose of LPS administered to adult male and female Siberian hamsters (Phodopus sungorus) activated the immune system by measuring levels of circulating cortisol and the proinflammatory cytokine TNF-α in the liver compared with saline-treated animals. We then investigated whether this same acute dose of LPS altered the microbiome 48 h after treatment. We found that, although LPS increased cortisol and liver cytokine levels, and produced changes in food intake and body mass in both sexes, immunological changes were independent of gut dysbiosis 48 h after LPS injection. These data suggest that an acute immune activation may not be capable of altering the gut microbiome in healthy individuals. It is likely, however, that this type of immune challenge may have other physiological impacts on the gut's vulnerability, and future studies will investigate these relationships further. © 2018 The Authors.

    Administration of erythropoietin (EPO) has been linked to cerebrovascular events. EPO reduces vascular conductance, possibly because of the increase in hematocrit. Whether EPO in itself affects the vasculature remains unknown; here it was evaluated in healthy males by determining systemic...... and cerebrovascular variables following acute (30,000 IU/d for 3 d; n=8) and chronic (5000 IU/week for 13 wk; n=8) administration of EPO, while the responsiveness of the vasculature was challenged during cycling exercise, with and without hypoxia.

    Full Text Available OBJECTIVE: Increasing evidences have suggested the pathogenic role of anti-neutrophil cytoplasmic antibodies (ANCA directing myeloperoxidase (MPO in ANCA-associated vasculitis (AAV. The current study aimed to analyze the association between the linear epitopes of MPO-ANCA and clinicopathological features of patients with AAV. METHODS: Six recombinant linear fragments, covering the whole length amino acid sequence of a single chain of MPO, were produced from E.coli. Sera from 77 patients with AAV were collected at presentation. 13 out of the 77 patients had co-existence of serum anti-GBM antibodies. Ten patients also had sequential sera during follow up. The epitope specificities were detected by enzyme-linked immunosorbent assay using the recombinant fragments as solid phase ligands. RESULTS: Sera from 45 of the 77 (58.4% patients with AAV showed a positive reaction to one or more linear fragments of the MPO chain. The Birmingham Vasculitis Activity Scores and the sera creatinine were significantly higher in patients with positive binding to the light chain fragment than that in patients without the binding. The epitopes recognized by MPO-ANCA from patients with co-existence of serum anti-GBM antibodies were mainly located in the N-terminus of the heavy chain. In 5 out of the 6 patients, whose sera in relapse recognize linear fragments, the reactivity to linear fragments in relapse was similar to that of initial onset. CONCLUSION: The epitope specificities of MPO-ANCA were associated with disease activity and some clinicopathological features in patients with ANCA-associated vasculitis.

    concomitant immunosuppressive therapy. Independent factors examined by Cox regression modeling were: gender (p 0.005), creatinine levels (p = 0.000), HLA-DR (p = 0.05), PRA-Maximum >70% (p = 0.014). Each factor was scored using integral coefficients to generate four different groups. The Kaplan-Meier survival analyzed by group produces an interpretable separation of the risk factors for graft loss. Conclusions: The outcome in patients treated with radiation therapy for acute renal graft rejection can be predicted by a novel scoring system. Patients with scores of three or less are able to achieve 100% renal graft salvage, while patients who have scores of 12 or higher are not able to be salvaged with the current radiation therapy regimen. Future studies should be directed toward identifying more effective treatment for patients who have a high score based on our criteria. The scoring system should be utilized to identify patients at risk who could benefit from radiation therapy. Further study with a randomized trial utilizing this scoring system is needed to confirm the validity of the scoring system in predicting graft survival and the efficacy of radiation in patients who receive radiation therapy for acute graft rejection

    INTRODUCTION: The gastrointestinal manifestations of Henoch-Schonlein purpura (HSP) are well characterised, but their recognition can be difficult when they occur in isolation. Furthermore, HSP can run a more serious course in adults, compared to children, in whom the disease usually occurs. MATERIALS AND METHODS: We describe two cases that illustrate the challenges of HSP with mesenteric vasculitis and the outcome in adults. CONCLUSION: Although self-limiting in most patients, the outcome of HSP in adults can be far from benign and even fatal.

    We herein describe two cases of refractory antineutrophil cytoplasmic antibody-associated vasculitis (AAV) complicated with diabetes insipidus (DI) possibly related to hypertrophic pachymeningitis (HP). One patient had microscopic polyangiitis and HP, which were refractory to cyclophosphamide, azathioprine, rituximab, mycophenolate mofetil (MMF), and mizoribine. Remission was finally achieved with the use of etanercept, but DI occurred 5 years later. The other patient had granulomatosis with polyangiitis, which that was refractory to cyclophosphamide, methotrexate, MMF, and rituximab. DI subsequently developed, but was successfully treated with etanercept. Dura mater hypertrophy was macroscopically observed in the latter case.

    Full Text Available Renal disease secondary to vasculitis associated with anti-neutrophil cytoplasmic antibodies (ANCA can lead to chronic renal disease requiring renal replacement therapy. In these patients, kidney transplantation offers excellent long-term rates of allograft and patient survival; consequently, they can be trasplanted when the clinical disease activity has remitted. However, the risk of disease relapses in the renal allograft remains, although at lower rates due to modern immunosuppressive regimes. We describe the case of a male patient with extracapillary glomerulonephritis type III C-ANCA (+ who developed a recurrence in the renal allograft 8 years after transplantation. Intensive immunosupression with plasmapheresis controlled the disease.

    Status epilepticus is a neurologic emergency with high morbidity and mortality requiring neurointensive care and treatment of systemic complications. This systematic review compiles the current literature on acute systemic complications of generalized convulsive status epilepticus in adults and their immediate clinical impact along with recommendations for optimal neurointensive care. We searched PubMed, Medline, Embase, and the Cochrane library for articles published between 1960 and 2016 and reporting on systemic complications of convulsive status epilepticus. All identified studies were screened for eligibility by two independent reviewers. Key data were extracted using standardized data collection forms. Thirty-two of 3,046 screened articles were included. Acute manifestations and complications reported in association with generalized convulsive status epilepticus can affect all organ systems fueling complex cascades and multiple organ interactions. Most reported complications result from generalized excessive muscle contractions that increase body temperature and serum potassium levels and may interfere with proper and coordinated function of respiratory muscles followed by hypoxia and respiratory acidosis. Increased plasma catecholamines can cause a decay of skeletal muscle cells and cardiac function, including stress cardiomyopathy. Systemic complications are often underestimated or misinterpreted as they may mimic underlying causes of generalized convulsive status epilepticus or treatment-related adverse events. Management of generalized convulsive status epilepticus should center on the administration of antiseizure drugs, treatment of the underlying causes, and the attendant systemic consequences to prevent secondary seizure-related injuries. Heightened awareness, systematic clinical assessment, and diagnostic workup and management based on the proposed algorithm are advocated as they are keys to optimal outcome.

    Background Despite all the advances in the treatment of childhood acute lymphoblastic leukemia, central nervous system relapse remains an important obstacle to curing these patients. This study analyzed the incidence of central nervous system relapse and the risk factors for its occurrence in children and adolescents with acute lymphoblastic leukemia. Methods This study has a retrospective cohort design. The studied population comprised 199 children and adolescents with a diagnosis of acute lymphoblastic leukemia followed up at Hospital das Clinicas, Universidade Federal de Minas Gerais (HC-UFMG) between March 2001 and August 2009 and submitted to the Grupo Brasileiro de Tratamento de Leucemia da Infância - acute lymphoblastic leukemia (GBTLI-LLA-99) treatment protocol. Results The estimated probabilities of overall survival and event free survival at 5 years were 69.5% (± 3.6%) and 58.8% (± 4.0%), respectively. The cumulative incidence of central nervous system (isolated or combined) relapse was 11.0% at 8 years. The estimated rate of isolated central nervous system relapse at 8 years was 6.8%. In patients with a blood leukocyte count at diagnosis ≥ 50 x 109/L, the estimated rate of isolated or combined central nervous system relapse was higher than in the group with a count 50 x 109/L at diagnosis seems to be a significant prognostic factor for a higher incidence of central nervous system relapse in childhood acute lymphoblastic leukemia.

    An in vitro crystal violet staining method using the rabbit cornea-derived cell line (SIRC-CVS) has been developed as an alternative to predict acute systemic toxicity in rodents. Seventy-nine chemicals, the in vitro cytotoxicity of which was already reported by the Multicenter Evaluation of In vitro Toxicity (MEIC) and ICCVAM/ECVAM, were selected as test compounds. The cells were incubated with the chemicals for 72 hrs and the IC(50) and IC(35) values (microg/mL) were obtained. The results were compared to the in vivo (rat or mouse) "most toxic" oral, intraperitoneal, subcutaneous and intravenous LD(50) values (mg/kg) taken from the RTECS database for each of the chemicals by using Pearson's correlation statistics. The following parameters were calculated: accuracy, sensitivity, specificity, prevalence, positive predictability, and negative predictability. Good linear correlations (Pearson's coefficient; r>0.6) were observed between either the IC(50) or the IC(35) values and all the LD(50) values. Among them, a statistically significant high correlation (r=0.8102, p50) values and the oral LD(50) values. By using the cut-off concentrations of 2,000 mg/kg (LD(50)) and 4,225 microg/mL (IC(50)), no false negatives were observed, and the accuracy was 84.8%. From this, it is concluded that this method could be used to predict the acute systemic toxicity potential of chemicals in rodents.
