Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a multipotent hematopoietic growth factor, which is mainly produced by T-cells and stromal cells. Beside the stimulating effects on mature granulocytes, it induces the expression of HLA class II-antigen on synovial tissue-cells in patients with rheumatoid arthritis. The concentrations of GM-CSF in the plasma of 87 patients with rheumatoid arthritis, 48 patients with spondyloarthropathy, 17 patients with systemic lupus erythematosus (SLE), and 43 healthy control persons were investigated. We used an immunoradiometric assay (IR-MA) with a detection limit of 30 pg/ml to measure the GM-CSF concentrations in plasma. The GM-CSF levels of 29 patients with severe rheumatoid arthritis (366 +/- 61 pg/ml, p less than 0.05), 58 patients with moderate rheumatoid arthritis (376 +/- 44 pg/ml, p less than 0.0001), and of 17 patients with SLE (256 +/- 41 pg/ml, p less than 0.05) were elevated compared to the control group (174 +/- 18 pg/ml). No significant differences in the mean GM-CSF plasma levels between the patients with spondyloarthropathy (190 +/- 32 pg/ml) and the control group were found. GM-CSF concentrations as high as 1300 pg/ml were detected in the synovial fluids of patients with rheumatoid arthritis. GM-CSF concentrations in the plasma of patients with severe rheumatoid arthritis were correlated with the plasma concentrations of the soluble interleukin-2-receptor (sCD25) (R = +0.53).

UI	MeSH Term	Description	Entries
D008180	Lupus Erythematosus, Systemic	A chronic, relapsing, inflammatory, and often febrile multisystemic disorder of connective tissue, characterized principally by involvement of the skin, joints, kidneys, and serosal membranes. It is of unknown etiology, but is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow.

D001172	Arthritis, Rheumatoid	A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated.	Rheumatoid Arthritis
D012217	Rheumatoid Factor	Autoantibodies found in adult RHEUMATOID ARTHRITIS patients that are directed against GAMMA-CHAIN IMMUNOGLOBULINS.	Factor, Rheumatoid
D013167	Spondylitis, Ankylosing	A chronic inflammatory condition affecting the axial joints, such as the SACROILIAC JOINT and other intervertebral or costovertebral joints. It occurs predominantly in young males and is characterized by pain and stiffness of joints (ANKYLOSIS) with inflammation at tendon insertions.

D015375	Receptors, Interleukin-2	Receptors present on activated T-LYMPHOCYTES and B-LYMPHOCYTES that are specific for INTERLEUKIN-2 and play an important role in LYMPHOCYTE ACTIVATION. They are heterotrimeric proteins consisting of the INTERLEUKIN-2 RECEPTOR ALPHA SUBUNIT, the INTERLEUKIN-2 RECEPTOR BETA SUBUNIT, and the INTERLEUKIN RECEPTOR COMMON GAMMA-CHAIN.

D015592	Immunoradiometric Assay	Form of radioimmunoassay in which excess specific labeled antibody is added directly to the test antigen being measured.	Assay, Immunoradiometric,Assays, Immunoradiometric,Immunoradiometric Assays
D016178	Granulocyte-Macrophage Colony-Stimulating Factor	An acidic glycoprotein of MW 23 kDa with internal disulfide bonds. The protein is produced in response to a number of inflammatory mediators by mesenchymal cells present in the hemopoietic environment and at peripheral sites of inflammation. GM-CSF is able to stimulate the production of neutrophilic granulocytes, macrophages, and mixed granulocyte-macrophage colonies from bone marrow cells and can stimulate the formation of eosinophil colonies from fetal liver progenitor cells. GM-CSF can also stimulate some functional activities in mature granulocytes and macrophages.
