A solid phase radioimmunoassay has been developed to detect circulating autoantibodies to neutrophil cytoplasmic antigens in systemic vasculitis. After fractionation of these antigens by size, with gel filtration high performance liquid chromatography, sera from patients with clinically different
A prospective clinical study (1974-1988) was carried out in 33 patients with several types of systemic vasculitis (SV) presenting as fever of unknown origin (FUO) according to the 1961 Petersdorf and Beeson's criteria. Histological confirmation, either from biopsy or necropsy, was available in all
OBJECTIVE
To assess the possible association between the PTPN22 gene 1858C-->T polymorphism and the susceptibility to Henoch-Schönlein purpura (HSP) and determine if this polymorphism is implicated in the severity of this systemic vasculitis.
METHODS
Fifty-seven unselected patients from Northwest
Behcet disease (BD) is a chronic systemic vasculitis and considered as an autoimmune disease. Although rare, BD can be fatal due to ruptured vascular aneurysms or severe neurological complications. To date, no known biomarker has been reported for this disease, making it difficult to diagnosis in
Malignant rheumatoid arthritis (MRA) is a name for rheumatoid arthritis (RA) complicated with systemic vasculitis or other severe extra-articular manifestations, which can cause a fatal outcome. MRA is found in 4-5% of inpatients with RA. The male to female ratio is 1:1.45. Histologically, 3 main
OBJECTIVE
To study the expression of cell adhesion molecules in the renal biopsy specimens of patients with systemic vasculitis and Henoch-Schönlein purpura (HSP); to correlate this with the severity of glomerular inflammation.
METHODS
Renal biopsy specimens obtained from eight patients with
Wegener's granulomatosis (WG) is a systemic vasculitis which is diagnosed on clinicopathological findings. The diagnosis may be aided by the presence of anti-neutrophil cytoplasm antibodies (ANCA). In WG, ANCA are primarily directed to proteinase 3 (PR3), a serine protease of the azurophilic
A functional single nucleotide polymorphism (SNP) of PTPN22 gene encoding the protein tyrosine phosphatase has been reported to be associated with autoimmune disorders such as rheumatoid arthritis, systemic lupus erythematosus and type I diabetes. PTPN22 R620W polymorphism has a wide variation of
BACKGROUND
Various viruses have been implicated in the cause and pathogenesis of rheumatoid arthritis (RA). Hepatitis C virus (HCV) infection, which has been recognised as a cause of some autoimmune diseases, and which has been described as sometimes presenting with rheumatic manifestations
