Gout Gout Gout is a form of inflammatory arthritis characterized by recurrent attacks of a red, tender, hot, and swollen joint. Pain typically comes on rapidly, reaching maximal intensity in less than twelve hours. The joint at the base of the big toe is affected in about half of cases. It may also result in tophi, kidney stones, or urate nephropathy. Gout is due to persistently elevated levels of uric acid in the blood. This occurs due to a combination of diet and genetic factors. At high levels, uric acid crystallizes and the crystals deposit in joints, tendons, and surrounding tissues,
Biological therapy for inflammatory bowel disease IgG1 monoclonal antibody that was first approved by the FDA in 2009 to treat rheumatoid arthritis. Since, it has been approved to also treat psoriatic arthritis, ankylosing spondylitis, and moderately to severely active ulcerative colitis. Integrin receptor antagonists are different than TNF inhibitors because they block transmembrane receptors called integrins instead of cytokines like TNF. Integrins mediate adhesion, signaling, and migration in many different types of cells. During active periods of disease, cell adhesion molecules on the vascular endothelium increase in response to various proinflammatory cytokines. The alpha 4 integrin on inflammatory cells interacts with these adhesion molecules to allow
