OBJECTIVES To report the successful induction of remission with the monoclonal anti-CD20 antibody rituximab in a patient with hepatitis C virus (HCV) associated cryoglobulinaemic vasculitis and a non-Hodgkin's lymphoma (NHL) resistant to previously advocated conventional treatments. CASE REPORT The patient was a 45 year old woman with HCV associated(More)
The participation of the humoral immune system in rheumatoid arthritis (RA) is characterized by the production of rheumatoid factors (RF). RF are autoantibodies against the Fc part of IgG which are encoded by diverse germ-line genes. Most of the RF-encoding genes are unmutated, but in RA, a substantial quantity is encoded by somatically mutated genes. In(More)
The analysis of rearranged antibody-encoding genes from B cell foci in rheumatoid synovial tissue has characterized these cells as highly mutated memory B cells with a high proportion of members of the VH4 family. In order to characterize further the VH4 response in one patient, B cell-rich areas from different sections of synovial membrane (SM) were(More)
Seit 2006 ist Rituximab (RTX) für die Behandlung von Patienten mit rheumatoider Arthritis zugelassen, die auf eine frühere TNF-Blockertherapie nicht angesprochen bzw. diese nicht vertragen haben. In diesen überarbeiteten Therapieempfehlungen werden neue Studiendaten zur Evaluation des therapeutischen Ansprechens, zur Retherapie sowie die Bedeutung von(More)
Samples of peripheral blood from 26 patients with Crohn's disease (CD) and 26 healthy age- and sex-matched controls were tested simultaneously for B and T lymphocytes and T-lymphocyte subpopulations with receptors for IgM (TM) and IgG (TG). Patients with CD had reduced proportions of T lymphocytes, and this reduction showed a significant correlation to the(More)
We have partially sequenced the light chain variable regions expressed in three IgM-producing hybridomas generated from newborn mice or from manipulated animals suppressed for IgM production. In these lines a new V gene (V-lambda-X), exhibiting less than 60% homology to any known lambda or kappa V gene, is rearranged to J-lambda-2. The light chains produced(More)
OBJECTIVE To study immunological markers and compare these markers with standard measures for the clinical and immunological follow up of vasculitis activity in hepatitis C virus (HCV) associated cryoglobulinaemic vasculitis (CV). METHODS Serial serum samples from eight patients with newly diagnosed HCV associated CV were followed during interferon alpha(More)
OBJECTIVE Clinical measures of vasculitis activity (Birmingham vasculitis activity score = BVAS) and disease extent (Disease Extent Index = DEI), serological and immunological parameters were evaluated for the monitoring of hepatitis C virus (HCV)-associated cryoglobulinemic vasculitis (CV), treated with either cyclophosphamide or interferon-alpha 2b(More)
BACKGROUND Anti-neutrophil cytoplasmic antibodies (ANCA) directed against proteinase 3 (PR3) are highly specific for Wegener's granulomatosis (WG). Evidence for a pivotal role of PR3-ANCA in the induction of vasculitis has been demonstrated. B cell clusters have been observed within endonasal biopsy specimens. OBJECTIVES To determine whether B cell(More)
