We report a patient with anti-glomerular basement membrane disease who developed renal failure associated with systemic manifestations, including acute-phase inflammatory reactions and plasmacytosis. Renal tissue obtained by an open surgical biopsy showed circumferential cellular crescents, multinucleated giant cells, and exudation of fibrin in all glomeruli. Immunofluorescence microscopy demonstrated deposition of immunoglobulin G, C3, and membrane attack complex along glomerular capillary walls. Multinucleated giant cells were suggested to be macrophage-monocyte lineage because they were CD68 positive. Bone marrow aspiration showed an increase of plasma cells. Immunostaining showed intensive expression of interleukin-6 (IL-6) in practically every part of the renal sites involving multinucleated cells, crescents, tubules, and infiltrating cells, suggesting that one of the sources of systemically elevated IL-6 was the kidney. Serum IL-6, anti-glomerular basement membrane antibody, and acute-phase proteins were markedly elevated, and returned dramatically to the normal level after corticosteroid therapy and plasmapheresis. We believe that IL-6 played an important role in the development of many symptoms in the present case.

D007678 Kidney Glomerulus A cluster of convoluted capillaries beginning at each nephric tubule in the kidney and held together by connective tissue. Glomerulus, Kidney
D010950 Plasma Cells Specialized forms of antibody-producing B-LYMPHOCYTES. They synthesize and secrete immunoglobulin. They are found only in lymphoid organs and at sites of immune responses and normally do not circulate in the blood or lymph. (Rosen et al., Dictionary of Immunology, 1989, p169 & Abbas et al., Cellular and Molecular Immunology, 2d ed, p20) Plasmacytes,Cell, Plasma,Cells, Plasma,Plasma Cell,Plasmacyte
D001853 Bone Marrow The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.

D003176 Complement C3 A glycoprotein that is central in both the classical and the alternative pathway of COMPLEMENT ACTIVATION. C3 can be cleaved into COMPLEMENT C3A and COMPLEMENT C3B, spontaneously at low level or by C3 CONVERTASE at high level. The smaller fragment C3a is an ANAPHYLATOXIN and mediator of local inflammatory process. The larger fragment C3b binds with C3 convertase to form C5 convertase.

D005455 Fluorescent Antibody Technique Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.

D005921 Glomerulonephritis Inflammation of the renal glomeruli (KIDNEY GLOMERULUS) that can be classified by the type of glomerular injuries including antibody deposition, complement activation, cellular proliferation, and glomerulosclerosis. These structural and functional abnormalities usually lead to HEMATURIA; PROTEINURIA; HYPERTENSION; and RENAL INSUFFICIENCY. Bright Disease,Kidney Scarring,Glomerulonephritides,Scarring, Kidney
