low-purine diet

low-purine diet

a diet used as adjunct therapy for gout patients who suffer from a painful accumulation of salts of uric acid in the joints. Purine-rich foods are primary sources of uric acid. They include meat, poultry, fish, and particularly organ meats such as liver, kidney, and sweetbreads. Purine-rich foods are replaced in the diet by dairy products, eggs, and some vegetable sources of proteins. Low-purine diets should be a secondary source of treatment, with weight loss and adequate fluid intake being primary. Also called purine-restricted diet.

low-pu·rine di·et

(lō-pyūr'ēn dī'ĕt)
A diet low in precursors of purines (such as tissues rich in cells with abundant nuclei, as in liver and glandular meats) to minimize formation of uric acid. Useful in treatment of patients with gout or urate-containing renal calculi.

His owner, Shelley Gallagher of Sandy, Utah, had been feeding Armstrong a low-purine diet, giving him extra fluids to help dilute his urine, letting him out to urinate every few hours (including every night at 2 am), and obsessively monitoring him--all, ultimately, to no avail.
Although a strict low-purine diet isn't necessary, think about reducing your intake of foods such as liver and other offal, fish roe, meat extracts, poultry and pulses for five days out of seven.
Feeding a low-purine diet helps prevent urate stones, but the problem can be so severe that in some cases the only option is euthanasia.
The key to keeping urate-forming dogs healthy is to feed them a low-purine diet.
Urate stones can be dissolved with a combination of a low-purine diet, urine alkalization, and control of secondary infections.
A low-purine diet must be fed while giving allopurinol, as otherwise it predisposes dogs to the formation of xanthine stones and shells, making dissolution difficult.
On average, it takes about VA months for stones to dissolve using allopurinol in combination with a low-purine diet and urinary alkalizination, but it can take as little as one month or as long as 18 months.
In some cases, discontinuing allopurinol while feeding a low-purine diet has dissolved xanthine uroliths, but in general, treatment consists of surgical removal, urohydropropulsion (a nonsurgical procedure performed with the dog under anesthetic, in which the bladder is filled with saline through a catheter, and the bladder is manually squeezed to force stones out through the urethra), or lithotripsy (the use of high-energy sound waves to break up the stones).
It was formerly thought that low-purine diets were effective, but with such drugs as NSAIDs to relieve the initial attacks of pain and inflammation, and allopurinol and other drugs for long-term therapy when necessary, these bland diets are of little value.
