Anti-glomerular basement membrane (anti-GBM) disease accompanied by vasculitis that was not positive for antineutrophil cytoplasmic antibodies to myeloperoxidase and proteinase 3: a report of two cases and the incidence of anti-GBM disease at one institution.

Background: Anti-glomerular basement membrane (anti-GBM) disease is thought to be distinct from vasculitis. In contrast, there have been several papers suggesting the presence of angiitis in cases that were positive for anti-GBM antibody (Ab), as well as for either myeloperoxidase (MPO)- or proteinase 3 (PR3)-anti-neutrophil cytoplasmic antibody (ANCA) (Group I). We experienced four patients who had anti-GBM Abs, but not MPO- and PR3-ANCA (Group II), and two of these patients were found to have vasculitis.

Concurrent occurrence of allergic granulomatous angiitis and temporal arteritis: a case report and review of the literature.

Allergic granulomatous angiitis (AGA) is a disease entity that was first distinguished from classical polyarteritis nodosa by Churg and Strauss in 1951, and is characterized by the clinical features of allergic rhinitis or bronchial asthma, eosinophilia, and vasculitis. Allergic granulomatous angiitis has been described to mainly involve small vessels. We herein describe a case of Churg-Strauss syndrome which demonstrated the clinical and laboratory findings supporting a diagnosis of AGA and was also associated with the clinical and pathological findings for temporal arteritis, which was characterized by eosinophil infiltration and granuloma formation of the temporal artery (middle-sized vessel).

[Hemophagocytic syndrome associated with hypercytokinemia in a patients with rheumatoid arthritis].

A 65-year old female, who had been suffered from rheumatoid arthritis, was admitted to our hospital because of fever, oral ulcers, perianal skin ulcers, petechiae in the both legs, hepatosplenomegaly and cervical lymphadenopathy. Her laboratory data showed severe anemia, leukocytopenia, and thrombocytopenia as well as low PT activity, prolonged APTT, decreased fibrinegen and elevated FDP. In addition to raised values of liver enzymes and triglyceride, marked elevation of several cytokines were found.
