Systemic vasculitis is characterized by the presence of autoantibodies to neutrophil cytoplasmic antigens (ANCA). The role of T-lymphocytes in systemic vasculitis remains uncertain. In the present study, we attempted to explore the role of T-lymphocytes in systemic vasculitis by measuring the serum soluble interleukin 2 receptor (sIL2R) levels in seven vasculitic patients and comparing the sequ...

OBJECTIVE To evaluate the prevalence of antineutrophil cytoplasmic antibodies (ANCA) and rheumatic manifestations associated with chronic haematological malignancies. METHODS Two groups of patients were prospectively studied (group I: 60 patients with myelodysplastic syndromes and group II: 140 patients with lymphoid malignancies) for clinical 'immune' manifestations and ANCA. RESULTS In th...

BACKGROUND Antinuclear cytoplasmic antibodies (ANCA) are useful diagnostic serological markers for the most common forms of necrotising vasculitis. ANCA associated vasculitides represent distinctive clinicopathological categories--for example, Wegener's granulomatosis, Churg-Strauss syndrome, microscopic polyangiitis, and idiopathic necrotising crescentic glomerulonephritis, collectively known ...

The systemic vasculitides are a group of diseases where the primary pathological process is inflammatory injury to blood vessel walls. Their clinical manifestations are highly variable and range from organ specific disease to a systemic illness that can lead, if untreated, to multi-organ failure and death. The kidneys are often involved in systemic vasculitis, particularly in small vessel vascu...

Rheumatoid vasculitis is a rare, but most serious extra-articular complications of long-standing, seropositive rheumatoid arthritis (RA). Vasculitis of hepatic artery is an extremely rare but severe manifestation of rheumatoid vasculitis. A 72-year-old woman who presented with polyarthralgia for 2 months was diagnosed with early RA. Since she had manifestations of livedo reticularis, and liver ...

A common classification of cerebral vasculitis uses the size of the affected arteries and the etiology of the wall inflammation, but this classification scheme was established for systemic disease rather than cerebral disease [1,2,3,4]. Another way to classify cerebral vasculitis has been proposed by Kuker [4] dividing it into large vessel vasculitis (LVV), medium vessel vasculitis (MVV), and s...

Systemic sclerosis (SSc) is a multiorgan connective tissue disease characterized by autoantibody production and fibroproliferative stenosis of the microvasculature. The vascoluopathy associated with SSc is considered to be noninflammatory, yet frank vasculitis can complicate SSc, posing diagnostic and therapeutic challenges. Here, we have reviewed the literature for reports of small-, medium-, ...

PURPOSE OF REVIEW Vasculitis refers to heterogeneous clinicopathologic disorders that share the histopathology of inflammation of blood vessels. When unrecognized and therefore untreated, vasculitis of the nervous system leads to pervasive injury and disability making this a disorder of paramount importance to all clinicians. RECENT FINDINGS Remarkable progress has been made in the pathogenes...

We review the terminology used in the context of cutaneous vasculitis with discussion of cutaneous leukocytoclastic vasculitis, its clinical approach, differential diagnosis and treatment algorithm. Cutaneous vasculitis encompasses a wide spectrum of conditions of very different severity and urgency, from limited skin disease to severe systemic life-threatening vasculitis. This review will empo...

the tetrad of bronchial asthma, severe sinusitis, nasal polyp, eosinophilia, and systemic vasculitis is the main feature of allergic granulomatosis and angitis (churg- strauss syndrome). this vasculitis is usually seen idiopathic in patients with a long history of asthma; oral steroids using steroid inhalers, vaccination and desensitization might be triggering factors. drugs such as leukotriene...
