The crystallization of uric acidoften related to relatively high levels in the blood, is the underlying cause of gout. This can occur because of diet, genetic predisposition, or underexcretion of uratethe salts of uric acid. Studies syndroe the early s found that other dietary factors are not relevant.
Physical fitness, healthy weight, low-fat dairy nnyhan, and to a lesser extent, coffee and taking vitamin C, appear to decrease the risk of gout; [28] [29] [30] [31] however, taking vitamin C supplements does not appear to have a significant effect in people who already have established gout. Gout frequently occurs in combination with other medical problems. Diuretics have been associated with attacks of gout, but a low dose of hydrochlorothiazide does not seem to increase risk. Gout is a disorder of purine metabolism[8] and occurs when its final metabolite, uric acidcrystallizes in the form of monosodium urate, precipitating and forming deposits tophi in joints, on tendons, and in the surrounding tissues. The triggers for precipitation of uric acid are not well understood. While it may crystallize at normal levels, it is more lesch nyhan syndrome life expectancy to do so as levels increase. Gout may be diagnosed and treated without further investigations in someone with hyperuricemia and the classic acute arthritis of the base of the great toe known as podagra.
Synovial fluid analysis should be done if the dxpectancy is in doubt. A definitive diagnosis of gout is based upon the identification of monosodium urate crystals in synovial fluid or a tophus. This test is difficult to perform and requires a trained observer.

Febuxostat is only recommended in those who cannot tolerate allopurinol. Probenecid appears to be less lifd than allopurinol and is a second line agent. Lesinurad reduces blood uric acid levels by preventing uric acid absorption in the kidneys.]
In it something is. Now all became clear, many thanks for the help in this question.
I regret, but nothing can be made.
