monosodium urate crystals (MSU)within tissues. Elevate serum uric acid(SUA) Gout is a systemic disorder that results from the deposition of above aspecific threshold is a requirement for the formation of uric acid crystals. even hyperuricemia is the main cause defect pathogenesis in gout, many people which have hyperuricemia do not cause gout or evenform UA crystals. In fact, just5% of people that have hyperuriceamia above 9 mg/dL will Couse gout. Accordingly, it is believe that otherfactors like genetic predisposition alsohas effect in the incidence of gout 4,5.The term ‘gout’, is came from Latin word’gutta’ and French word gote, both meaning a drop of liquid.
many hundred yearsago gout was believed to be caused by drops of viscous humors that moves fromblood into the joints. It named as the ‘disease of Kings1, because of its relatedwith the kind of over-excess in food and wine, which poor human couldn’t afford. Gout is a chronic and progressive disorder,which results from an overload of uric acid in the body, which is actually awaste product2. This overload of uric acid causethe formationof small crystals of urate which deposit in the tissues of the body, especiallythe joints. These deposits cause recurring attacks of joint inflammation(arthritis).Acute and chronic forms of gout are recognized. Acute goutis determine byrapid onset of excruciating pain and swelling associated with redness of theaffected joint.
In the primary attacks, the onset is in the firstmeta-tarsophalangeal joint (MTP), and this joint is affected in some 90 % ofpatients withgout. A Chronic form of gout is linked with deposition of crystals in softtissues, joints, bones and tendons3. They result abrasion and destruction ofthe bone, which leading to paralyze. The patients, with chronic gouts,are usuallythose, whose with uncontrolled hyper- uricaemia. Primary gout is related to lowexcretion or high production of uric acid1. Secondary gout is result from myeloproliferativediseases or their treatment, therapeutic regimens generating hyperuricaemia,renal failure, renal tubular disorders, cause poisoning, hyper proliferativeskin disease, enzymatic failure etc.
(e.g., deficient hypoxanthine-guanine phosphoribosyltransferase, and glycogen storage diseases). It is a rheumatic syndrome resultedby an inflammatory response to the production of monosodium urate monohydratecrystals, which lead to hyperuricaemia (increase blood uric acid levels)1,3.But some patient may only cause hyperuricaemia without having appearance ofgout, such as arthritis orkidneyproblems. It is related to as asymptomatic hyperuricaemia, which is consideredas a progenitor state to the formation of gout2.
Gout affects quality of lifeThis disorder is very painful andbecomes a main obstacle in professional or social life, because of inflammationand tremendous pain.
