Extractions: Verified by National Institute of Allergy and Infectious Diseases (NIAID) May 2005 Sponsors and Collaborators: National Institute of Allergy and Infectious Diseases (NIAID) Immune Tolerance Network Information provided by: National Institute of Allergy and Infectious Diseases (NIAID) ClinicalTrials.gov Identifier: Purpose Antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis is the most common type of small blood vessel inflammation in adults. ANCA-associated vasculitis includes Wegener's granulomatosis (WG) and microscopic polyangiitis (MPA). Rituximab is a man-made antibody used to treat certain types of cancer. The purpose of this study is to determine the effectiveness of rituximab in treating adults with WG and MPA. Study hypothesis: Rituximab is not inferior to conventional therapy in its ability to induce disease remission by Month 6. Condition Intervention Phase Vasculitis
Extractions: Verified by University Medical Centre Groningen February 2005 Sponsored by: University Medical Centre Groningen Information provided by: University Medical Centre Groningen ClinicalTrials.gov Identifier: Purpose The purpose of this study is to determine the efficacy and safety of a new drug, mycophenolate mofetil, for the treatment of relapses of ANCA-associated vasculitis (Wegener's granulomatosis or microscopic polyangiitis). Therefore, we compare the standard therapy with cyclophosphamide to mycophenolate mofetil. We expect mycophenolate mofetil to be less toxic and almost equally effective as cyclophosphamide. Condition Intervention Phase Wegener's Granulomatosis Study Design: Treatment, Randomized, Open Label, Active Control, Parallel Assignment, Safety/Efficacy Study Official Title: Comparative Study of the Efficacy of Induction Therapy with Cyclophosphamide or Mycophenolate Mofetil for Non-Life-Threatening Relapses of PR3- or MPO-ANCA Associated Vasculitis Further Study Details: Primary Outcomes: remission induction rate; disease free survival after 2 and 4 years

Extractions: Background This small vessel vasculitis is also known as microscopic polyangiitis . It is a disease of middle aged males and mainly affects the kidneys, skin, and lungs. Like polyarteritis nodosa , the disease presents with constitutional symptoms of fever, malaise, myalgia, and weight loss. Skin lesions occur in 30-50% presenting with purpura and rarely nodules and ulcers. One of the diagnostic hallmarks is the presence of antineutrophil cytoplasmic antibodies (p-ANCA). The kidney shows a focal and segmental glomerulonephritis. The skin shows a leukocytoclastic vasculitis. In nodular skin lesions, the vessels of the dermis and subcutaneous fat may be involved. SYNONYMS Microscopic polyangiitis INCIDENCE AGE RANGE-MEDIAN Mean 50 years SEX (M:F) Male slight predominance LABORATORY/RADIOLOGIC/OTHER TESTS CHARACTERIZATION Laboratory Markers ANCA PR3 ANCA and MPO-ANCA are present in 40% and 50% of cases with 10% negative GROSS APPEARANCE/CLINICAL VARIANTS CHARACTERIZATION General VARIANTS Pulmonary-Renal syndrome Arch Intern Med 1996;156:440-445

Extractions: colon; We reviewed the medical records of 62 patients with systemic small and medium-sized vessel vasculitides and gastrointestinal tract involvement followed at our institution between 1981 and 2002. This group included 46 men and 16 women (male:female ratio, 2.9), with a mean age of 48 +/- 18 years. Vasculitides were distributed as follows: 38 polyarteritis nodosa (21 related to hepatitis B virus), 11 Churg-Strauss syndrome, 6 Wegener granulomatosis, 4 microscopic polyangiitis, and 3 rheumatoid arthritis-associated vasculitis. Gastrointestinal manifestations were present at or occurred within 3 months of diagnosis in 50 (81%) patients and were mainly abdominal pain in 61 (97%), nausea or vomiting in 21 (34%), diarrhea in 17 (27%), hematochezia or melena in 10 (16%), and hematemesis in 4 (6%). Gastroduodenal ulcerations were detected endoscopically in 17 (27 %) patients, esophageal in 7 (11%), and colorectal in 6 (10%), but histologic signs of vasculitis were found in only 3 colon biopsies. Twenty-one (34%) patients had a surgical abdomen; 11 (18%) developed peritonitis, 9 (15%) had bowel perforations, 10 (16%) bowel ischemia/infarction, 4 (6%) intestinal occlusion, 6 (10%) acute appendicitis, 5 (8%) cholecystitis, and 3 (5%) acute pancreatitis. (Some patients had more than 1 condition.) Sixteen (26%) patients died.

Extractions: May 2000 Newsletter PSA Consult Volume III No. 5 May 31, 2000 ANCA AND ASSOCIATED DISEASE: UPDATE Antibodies reacting with the cytoplasm of neutrophils were first noted in patients with necrotizing glomerulonephritis by Davies in 1982. Subsequent observations have identified ANCAs as specific antibodies to antigens in neutrophil granules and monocyte lysosomes. ANCA results are universally accepted as important adjuncts to the diagnosis of primary systemic small vessel vasculitis, however, neither the American College of Rheumatology (1990) nor the Chapel Hill Consensus Conference (1994) classification schemes of vasculitis currently use ANCA or ANCA-related antigen specificity as part of their diagnostic criteria. The Chapel Hill systemic vasculitis classification scheme is currently being revised to allow for ANCA and ANCA-associated antigen specificity. ANCA are also useful in monitoring disease activity, relapses, and response to treatment. Table I lists the current clinical indications for ANCA testing. Problems with ANCA testing and test interpretation have resulted in incorrect diagnoses, errors in management and nonuniformity of test results. An International Consensus Conference Statement on testing and reporting of ANCA was published in the Am J Clin Path in 1999. This statement recommends a combination of indirect immunofluorescence (IIF) with neutrophils and enzyme-linked immunosorbent assays (ELISAs) that detect the ANCA specific antigens, proteinase 3 (PR3) and myeloperoxidase (MPO), to demonstrate ANCA-associated disease.

Extractions: Welcome to Megan's Home - The place where you can learn all about this wonderful child and Microscopic Polyangiitis (MPA). Megan was diagnosed with MPA in January 2005. In September 2004 she had been diagnosed with Juvenile Rheumatoid Arthritis (JRA) after suffering with painful and stiff joints (ankles, wrists, hands, and back). It was later that we learned that this probably signaled the beginning of the problems with the rare autoimmune disease, MPA.
