Neutrophil extracellular traps are associated with a unique form of cell death distinct from apoptosis or necrosis, whereby invading microbes are trapped and killed. Neutrophil extracellular traps can contribute to autoimmunity by exposing autoantigens, inducing IFN-α production, and activating the complement system. The association of neutrophil extracellular traps with autoimmune diseases, pa...

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides are characterized by destruction of small vessels, granulomatous inflammation of the respiratory tract and necrotizing glomerulonephritis. This review describes the clinical diagnosis and therapy as well as the pathophysiology of ANCA-associated vasculitides with a specific focus on the interplay of ANCAs with activated neutrop...

We describe a case of Wegener's disease with massive painful bilateral submandibular gland enlargement as the presenting symptom. The diagnosis was based on histologically documented nasal mucosa involvement, focal necrotizing glomerulonephritis, episcleritis and anti-neutrophil cytoplasmic antibody.

CASE REPORT 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. DISCUSSION Although her anti-neutrophil cytoplasmatic antibody (ANCA) sta...

The observation data of 22 children with systemic vasculitis (SV) and morphologically verified nephritis is presented. Emphasis was put on extrarenal manifestations SV in childhood, analysis clinical, laboratory, immunological, morphological changes factors influencing the course prognosis. It has been established that often manifests general non-specific constitutional symptoms, involvement EN...

Introduction: In this study, we examined the role of immunological factors on sudden sensory neural hearing loss (SSNHL).   Materials and Methods: This prospective case-controlled study was performed in patients with SSNHL who referred to the ear, nose, and throat (ENT) ward. Fifty-six patients with SSNHLoccurring within a 72-hr period were selected as the case group and 56 participants who ha...

Enormous progress has been made during the last 25 years in our understanding of the aetiopathogenesis of the anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitides (AAV). This has led to improvements in early diagnosis, treatment and secondary prevention of these diseases. Nevertheless, there are still unmet needs in the AAV. With respect to diagnosis and follow-up, sensitive ...

Organizing pneumonia (OP) is a clinicopathological entity that occurs idiopathically or in association with several conditions, but there are few reports about myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA)-associated OP. We describe a patient with OP whose clinical conditions improved spontaneously. Moreover, serum MPO-ANCA titers paralleled the clinical activity of the diseas...

Sir, Tubulointerstitial diseases including tubulointerstitial nephritis (TIN) have an impact on overall renal function and eventual prognosis of renal diseases [1]. However, the detailed pathogenesis of human TIN has not been fully studied. Renal involvement in anti-neutrophil cytoplasmic antibody (ANCA)-associated diseases shows mainly glomerular lesion, especially necrotizing crescentic glome...
