IgG4 disease was first described in 2001 in a seminal paper by Hamano and colleagues: Syndrome of exocrine gland infiltration with associated raised serum IgG4 levels. IgG4 disease is manifested by the hallmark histopathologic features of lymphoplasmacytic infiltration of IgG4-positive plasma cells, storiform fibrosis, and obliterative phlebitis. Hypertrophic pachymeningitis (HP) has been incre...
Antineutrophil cytoplasmic antibodies are associated with pauci-immune small-vessel vasculitis and crescentic glomerulonephritis. Cathelicidin LL37 is the human member of a family of antimicrobial peptides that are released from activated neutrophils and monocytes at sites of acute inflammation. Zhang and colleagues evaluated serum levels of cathelicidin LL37 and interferon-alpha in patients wi...
Autoantibodies against various “self” intraor extracellular, cell surface-bound or soluble antigens are frequently present in the sera of patients with autoimmune diseases. Regardless of their precise role in the pathogenesis of these diseases, testing for autoantibodies constitutes an integral part of the initial diagnostic workup of patients with organ-specific or systemic autoimmune diseases...
Antineutrophil cytoplasmic antibodies (ANCA) are well known to be associated with several types of vasculitis, including pauci-immune crescentic glomerulonephritis, a form of rapid progressive glomerular nephritis (RPGN). ANCA vasculitis has also been reported after administration of propylthiouracil, hydralazine, cocaine (adulterated with levimasole), allopurinol, penicillamine and few other d...
Pulmonary fibrosis (PF) is an uncommon manifestation observed in patients with antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV), particularly microscopic polyangiitis (MPA). While patients with PF associated with AAV seem to e Brun, MD, Philip D, avid Saadoun, MD, PhD patients with PF associated with AAV, fulfilling the American College of Rheumatology criteria and/or Ch...
OBJECTIVE . The predictive value of antineutrophil cytoplasmic antibodies (ANCA) as markers of clinical activity of small vessel vasculitis is controversial. We reviewed the outcome of patients with ANCA-associated vasculitis from a single center and evaluated the predictive value of ANCA as markers of relapse. METHODS The medical history of all consecutive patients with ANCA-associated vascu...
A 65-year-old woman with previously known rheumatoid arthritis and chronic renal failure of possible glomerular origin was admitted to the hospital because of hemoptysis and respiratory insufficiency. Antineutrophil cytoplasmic antibodies (ANCAs) with antimyeloperoxidase activity were detected in her serum. The lung biopsy specimen evidenced alveolar hemorrhage. Under immunosuppressive therapy ...
PURPOSE OF REVIEW Induction treatment of antineutrophil cytoplasmic antibodies (ANCA) associated vasculitis (AAV) is not always successful and nonresponding patients are considered refractory. RECENT FINDINGS Refractory disease should be subdefined to the treatment that was received. Cyclophosphamide refractory AAV occurs in up to 5% of patients. Many more patients develop contraindications t...
