The disease is often, but not always, associated with elevated serum uric acid levels. Clinical manifestations include acute and chronic arthritis, tophi, interstitial renal disease and uric acid nephrolithiasis. The diagnosis is based on the identification of uric acid crystals in joints, tissues or body fluids.
Calcium pyrophosphate dihydrate crystal deposition disease (CPPD) occurs when these crystals form deposits in the joint and surrounding tissues. The crystal deposits. Surprising Health Benefits of Sex. How would you like a stronger immune system or better sleep? Action between the sheets can help you get all of this and more. Pseudogout is the result of CPPD disease. The crystals causing pseudogout are calcium pyrophosphate crystals.
Treatment goals include termination of the acute attack, prevention of recurrent attacks and prevention of complications associated with the deposition of urate crystals in tissues. Pharmacologic management remains the mainstay of treatment. Acute attacks may be terminated with the use of nonsteroidal anti- inflammatory agents, colchicine or intra- articular injections of corticosteroids. Probenecid, sulfinpyrazone and allopurinol can be used to prevent recurrent attacks.
Gout is a painful and potentially disabling form of arthritis that has been around since ancient times. It is sometimes referred to as the âdisease of kings.
Obesity, alcohol intake and certain foods and medications can contribute to hyperuricemia. These potentially exacerbating factors should be identified and modified. BROSS, M. D., University of Mississippi Medical Center, Jackson, Mississippi

Gout is a disease resulting from the deposition of monosodium urate crystals in synovial fluid and other tissues or the formation of uric acid stones in the kidney. Although the prevalence of gout is equal in men and women, men are six times more likely to have serum uric acid concentrations above 7 mg per d. L (4. 20 . Gout typically occurs during middle age and is uncommon before the age of 3.
Women rarely have gouty arthritis attacks before menopause.
H of 7, more than 9. Uric acid, the end product of purine metabolism, is a waste product that has no physiologic role. Humans lack uricase, an enzyme that breaks down uric acid into a more water- soluble product (allantoin), thus preventing uric acid accumulation. Increased serum uric acid concentration is a result of either overproduction or underexcretion of uric acid. In 9. 0 percent of patients, gout is caused by the underexcretion of uric acid.
Conversely, many persons with hyperuricemia never experience an attack of gouty arthritis.
A patient on a regular diet who excretes more than 8. The gastrointestinal tract eliminates the other one third to one fourth. Under normal conditions, uric acid is filtered in the glomeruli of the kidney, reabsorbed in the proximal tubule and secreted distally. Tubular secretion is almost entirely responsible for the excretion of uric acid. Renal management of uric acid is defective in approximately 9. However, polyarthric attacks can also occur. More than 7. 5 percent of acute gout attacks affect a joint in the lower extremity, especially the first metatarsophalangeal joint. Podagra, an acute attack of gout in the great toe, accounts for over 5. Approximately 8. 5 to 9. Joint involvement in polyarthric attacks appears to have an ascending, asymmetric pattern. In addition to the great toe, other areas affected include the insteps, heels, ankles, knees, fingers, wrists and elbows.
Acute attacks usually peak within one to two days of symptom onset. Untreated attacks may last seven to 1. Attacks usually start during the night, and moderate pain in a joint is first noticed. The pain becomes persistently worse and has a continuous, gnawing quality. The joints in the great toe and other parts of the lower extremity are generally the first articulations to be affected. These joints are common sites of attack because of lower body temperature and decreased monosodium urate solubility. Lower extremity trauma can also lead to an attack. Trauma induced in weight- bearing joints as a result of routine activities causes synovial effusions during daytime hours. At night, water is reabsorbed from the joint spaces, leaving a supersaturated concentration of monosodium urate. Pain and inflammation are produced when uric acid crystals activate the humoral and cellular inflammatory processes.
At this point, the physician usually decides whether or not to initiate prophylactic hyperuricemic therapy. Generally, patients with hyperuricemia and recurrent attacks, chronic gout, tophi, gouty arthritis or nephrolithiasis should be treated. Some investigators argue that the first attack of acute gouty arthritis is grounds for the initiation of hyperuricemic treatment. Others contend that a first attack is easily treated and recommend withholding prophylactic therapy until additional attacks occur.
They are a late complication of hyperuricemia. Rarely, tophi can develop without previous acute gouty arthritis.
Acute gouty nephropathy usually results from the massive malignant cell turnover that occurs with the treatment of myeloproliferative or lymphoproliferative disorders. The blockage of urine flow secondary to the precipitation of uric acid in the collecting ducts and ureters can lead to acute renal failure. Long- term deposition of crystals in the renal parenchyma can cause chronic urate nephropathy. The formation of microtophi causes a giant cell inflammatory reaction. This results in proteinuria and inability of the kidney to concentrate urine.
Radiography is not very useful in diagnosing initial attacks of acute gouty arthritis. The radiographic findings are generally nonspecific, consisting of soft tissue swelling around a joint. Bony abnormalities indicate the presence of chronic gout. In general, gout must be untreated or inadequately treated for approximately 1. Classic radiologic features of gout include tophi, an overhanging edge of cortex and a âpunched- outâ erosion of bone with sclerotic borders
Tophaceous gout should be considered when a mass reveals heterogeneously low to intermediate signal intensity, particularly if adjacent bone shows erosive changes or other joints are involved.
However, aspiration repeated five hours to one day later shows crystals in the synovial fluid of most of these patients.
Three treatments currently available for acute gouty arthritis attacks are nonsteroidal anti- inflammatory drugs (NSAIDs), colchicine and corticosteroids.
