[The rheumatoid rosette test in bacterial endocarditis. A non-specific test for inflammation (author's transl)]. 1978

J P Bouvet, and H Dechy, and A Guilabert, and R Levy, and M Dorra

The rheumatoid rosette test was performed in 33 patients with febrile valvular cardiopathy. In 19 cases bacterial endocarditis was proved by blood culture or by histological examination. The test was positive in 3 cases out of 5 during the first ten days of the fever (group A1), in 6 cases out of 6 after the tenth day (group A2), and in 4 out of the 8 already treated patients (group A3). In 3 positive cases, successive measurements, before and during treatment, showed a rapid fall in rosette levels. In controls patients, the test was positive 8 out of 9 cases with febrile valvular cardiopathy without endocarditis (group B) and in 5 out of 5 cases in which bacterial endocarditis was probable but not proved (group C). The increase in rheumatoid rosette levels seems therefore to be non specific of bacterial endocarditis. Nevertheless it could be a good test for biological activity of the disease in treated patients. The origin and signification of the rheumatoid rosette forming cells are discussed.

UI	MeSH Term	Description	Entries
D007249	Inflammation	A pathological process characterized by injury or destruction of tissues caused by a variety of cytologic and chemical reactions. It is usually manifested by typical signs of pain, heat, redness, swelling, and loss of function.	Innate Inflammatory Response,Inflammations,Inflammatory Response, Innate,Innate Inflammatory Responses
D007694	Killer Cells, Natural	Bone marrow-derived lymphocytes that possess cytotoxic properties, classically directed against transformed and virus-infected cells. Unlike T CELLS; and B CELLS; NK CELLS are not antigen specific. The cytotoxicity of natural killer cells is determined by the collective signaling of an array of inhibitory and stimulatory CELL SURFACE RECEPTORS. A subset of T-LYMPHOCYTES referred to as NATURAL KILLER T CELLS shares some of the properties of this cell type.

D004697	Endocarditis, Bacterial	Inflammation of the ENDOCARDIUM caused by BACTERIA that entered the bloodstream. The strains of bacteria vary with predisposing factors, such as CONGENITAL HEART DEFECTS; HEART VALVE DISEASES; HEART VALVE PROSTHESIS IMPLANTATION; or intravenous drug use.

D004698	Endocarditis, Subacute Bacterial	ENDOCARDIUM infection that is usually caused by STREPTOCOCCUS. Subacute infective endocarditis evolves over weeks and months with modest toxicity and rare metastatic infection.

D006242	Haptoglobins	Plasma glycoproteins that form a stable complex with hemoglobin to aid the recycling of heme iron. They are encoded in man by a gene on the short arm of chromosome 16.	Haptoglobin
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D012217	Rheumatoid Factor	Autoantibodies found in adult RHEUMATOID ARTHRITIS patients that are directed against GAMMA-CHAIN IMMUNOGLOBULINS.	Factor, Rheumatoid
D012397	Rosette Formation	The in vitro formation of clusters consisting of a cell (usually a lymphocyte) surrounded by antigenic cells or antigen-bearing particles (usually erythrocytes, which may or may not be coated with antibody or antibody and complement). The rosette-forming cell may be an antibody-forming cell, a memory cell, a T-cell, a cell bearing surface cytophilic antibodies, or a monocyte possessing Fc receptors. Rosette formation can be used to identify specific populations of these cells.	Immunocytoadherence,Formation, Rosette,Formations, Rosette,Immunocytoadherences,Rosette Formations
