OBJECTIVES: Behçet's disease (BD), an auto-inflammatory vasculitis with oro-genital ulcerations, skin lesions and uveitis, is regarded as T cell mediated. A successful trial with rituximab suggests an additive role for B cells in the pathogenesis. Therefore, we studied B cell abnormalities in BD patients and the effect of TNF-blocking therapy. METHODS: B cells in blood (n = 36) and tissue (n = 6) of BD patients were analysed with flow cytometry and/or immunohistochemistry and compared with healthy controls (n = 22)...

In patients with rheumatic diseases, reliable markers for determining disease activity are scarce. One potential parameter is the level of immunoglobulin free light chains (FLCs), which is known to be elevated in the blood of patients with certain rheumatic diseases. Few studies have quantified FLCs in urine, a convenient source of test sample, in patients with different rheumatic diseases. We carried out a retrospective analysis of patients with rheumatic disease attending the University hospital of Goettingen, Germany...

Antineutrophil cytoplasm antibody (ANCA)-associated vasculitides are small-vessel vasculitides that include granulomatosis with polyangiitis (formerly Wegener's granulomatosis), microscopic polyangiitis, and eosinophilic granulomatosis with polyangiitis (Churg-Strauss syndrome). Renal-limited ANCA-associated vasculitides can be considered the fourth entity. Despite their rarity and still unknown cause(s), research pertaining to ANCA-associated vasculitides has been very active over the past decades. The pathogenic role of antimyeloperoxidase ANCA (MPO-ANCA) has been supported using several animal models, but that of antiproteinase 3 ANCA (PR3-ANCA) has not been as strongly demonstrated...

We report the case of a 40-year-old female transplant patient with undiagnosed ANCA-associated vasculitis (AAV) and renal allograft dysfunction who achieved disease remission with restoration of transplant function following induction therapy with rituximab. There are currently no trial data looking at the use of rituximab for induction of remission of renal transplant patients with AAV. Although recurrence of AAV following renal transplantation is rare, such patients have invariably had multiple previous exposures to induction and maintenance immunosuppressive regimens, often limiting treatment options post-transplantation...

INTRODUCTION: We investigated the relationships between glucocorticoid (GC) use, disease activity, and changes in body mass index (BMI) in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). METHODS: We analyzed AAV patients enrolled in the Rituximab in ANCA-Associated Vasculitis (RAVE) trial. GC use, BMI, and disease activity were measured regularly during the trial period. We performed mixed effects regressions to examine the associations of time-dependent cumulative average GC use and disease activity with changes in body mass index (BMI) over time, while adjusting for potential confounders...

PURPOSE OF REVIEW: 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. RECENT FINDINGS: 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...

In the last few decades a number of small, often largely unrecognized steps have fundamentally changed the management of systemic lupus erythematosus (SLE). The current goal is to stop all disease activity without long-term use of more than 5 mg prednisolone per day. Remission, i.e. absence of activity in the SLE activity score of choice, is the defined target in the treat to target approach. The essential basic measures include life-long hydroxychloroquine as well as protection from sunlight (UV) and vitamin D substitution...

Mixed cryoglobulinemic vasculitis is associated with the monoclonal expansion of pathognomonic B cells in chronic hepatitis C. Recently, treatment with B-cell depletion, including rituximab, a CD20 monoclonal antibody, has been successful in achieving remission from the active disease. We investigated whether B-cell depletion therapy has an impact on activation of non-B cells in the periphery. Results demonstrated that B-cell depletion therapy is associated with a statistically significant decline in activated T cells, from pretherapy to follow-up while on rituximab therapy: CD4+ CD38+ HLA-DR+ (DR+), CD8+ CD38, CD8+ CD38+ DR+, and CD8+ DR+...

PURPOSE OF REVIEW: The primary systemic vasculitides represent a spectrum of rare but life-threatening conditions that may also affect the eye in various forms. This article reviews recently published data on ocular manifestations of systemic vasculitis. RECENT FINDINGS: Early diagnosis and timely treatment has led to better visual outcomes in giant cell arteritis (GCA). Gene expression from orbital tissues could distinguish granulomatosis with polyangiitis (GPA) from sarcoidosis and Graves disease, but not from idiopathic orbital inflammation...

Raynaud's phenomenon refers to reversible spasms of the peripheral arterioles that can be primary Raynaud's phenomenon (PRP) or secondary Raynaud's phenomenon (SRP) to underlying connective tissue disease, both of which are characterized by a triphasic color response triggered by cold exposure or stress. PRP is typically a benign disease, whereas SRP may progress into digital ulcers and/or gangrene. Here, we report a case of a 55-year-old female diagnosed with PRP 7 years ago. Treatment with first-line agents, including calcium channel blocker, aspirin, and phosphodiesterase inhibitor, did not control her symptoms, which progressed to digital ulceration and gangrene...

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that affects multiple systems. Myelopathy is one of 19 neuropsychiatric syndromes related to SLE defined by the American College of Rheumatology. Although infrequent, it is a severe manifestation, leading to motor and sensory deficits, and sphincter dysfunction. The pathogenesis is not clearly known, but may be related to arterial thrombosis and vasculitis. Diagnosis is based on clinical findings, laboratory tests and the use of gadolinium-enhanced magnetic resonance imaging...

BACKGROUND: Pauci-immune glomerulonephritis is the most common cause of aggressive glomerulonephritis and occurs as a renal-limited disease or as a component of systemic necrotizing small-vessel vasculitis. It is characterized by paucity of staining for immunoglobulins, by immunofluorescence along with fibrinoid necrosis and crescent formation by light microscopy, while the vast majority of patients have anti-neutrophil cytoplasmic antibodies (ANCA) in their circulation, which also participate in the pathogenesis of the disease...

BACKGROUND: Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) comprises microscopic polyangiitis (MPA), granulomatosis with polyangiitis (GPA) and eosinophilic GPA (EGPA). Myeloperoxidase (MPO) and proteinase 3 (PR3) are the main antigens for ANCA. AAV is a common multisystem autoimmune disease and most of the studies on AAV have been conducted in Western countries. Nowadays in China many efforts are made to investigate this disease. SUMMARY: This review highlights the progress in the prevalence, management and outcomes of AAV in Chinese patients...

Henoch-Schonlein purpura, also called IgA-vasculitis, is a systemic small vessels vasculitis with immunoglobulin A1-dominant immune deposits. The optimal treatment remains controversial. Because IgA-vasculitis is characterized by leukocyte infiltration of the blood vessel walls along with immunoglobulin A deposition, and because glucocorticosteroids inhibit inflammatory processes, early administration of glucocorticosteroids has been postulated to be effective, but this indication remains controversial. Immunosuppressive agents (azathioprine, cyclophosphamide, cyclosporine, mycophenolate) have been used in combination with glucocorticosteroids without definitive evidence of effectiveness...

OBJECTIVES: S100A8/A9 (calprotectin) has shown promise as a biomarker for predicting relapse in AAV. This study investigated serum S100A8/A9 levels as a biomarker predicting future relapse in a large cohort of patients with severe ANCA-associated vasculitis (AAV). METHODS: Serum levels of S100A8/A9 were measured at baseline, months 2, and 6 following treatment initiation in 144 patients in the RAVE trial (cyclophosphamide/azathioprine vs. rituximab for induction of remission) who attained complete remission...

Objective To examine the impact of antineutrophil cytoplasmic antibody (ANCA) type and ANCA-associated vasculitis (AAV) diagnosis on demographic features, disease manifestations, and clinical outcomes. We focused on patients that account for the differences between ANCA type and disease type classifications: anti-myeloperoxidase (MPO) ANCA-positive and ANCA-negative patients with granulomatosis with polyangiitis (GPA). Methods Pooled analysis of the Wegener's Granlomatosis Etanercept Trial (WGET) and the Rituximab in AAV (RAVE) trial comparing MPO-ANCA+ GPA and ANCA-negative GPA patients to proteinase 3 (PR3) ANCA+ GPA and MPO-ANCA+ microscopic polyangiitis (MPA) patients...

OBJECTIVES: IgG4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory condition that can affect multiple organs and lead to tumefactive, tissue-destructive lesions. Reports have described inflammatory aortitis and periaortitis, the latter in the setting of retroperitoneal fibrosis (RPF), but have not distinguished adequately between these 2 manifestations. The frequency, radiologic features, and response of vascular complications to B cell depletion remain poorly defined...
