Pathogenesis of acute gouty inflammation (perceived and designed by Dr. EL-Shahaly). Gout distinguished itself in the history of Homo sapiens since time immemorial. It appeared in medical records very early in the history of medical writing, and was also mentioned in the biographies of many famous names. It was depicted as the fate of a life of affluence as much as the challenge to a physician’s skill, and truly it was. More recently, thanks to quantum leaps in molecular biology, diagnostic modalities, and pharmacotherapy, we enjoy deeper understanding of the disease and a more sophisticated armamentarium. Sometimes a buildup can occur if too much uric acid is produced or the kidneys can’t properly dispose of it.

The maintenance dose varies, averaging 500 to 1,000 mg 2 or 3 times a day. A 24-hour urine test for uric acid levels is necessary when considering a uricosuric agent. Because results are partly affected by diet, it is best to repeat the test on two separate occasions. If the 24-hour urine levels are abnormally elevated, then uricosuric agents should not be used because of the increased risk of urate stones. An additional proposed mechanism involves the role of an inflammasome and interleukin 1 (IL-1) in the pathogenesis of inflammation induced by MSU and CPPD . Cryopyrin inflammasome detects MSU and CPPD crystals and activates IL-1, resulting in an inflammatory cascade.

Relieving Acute Flare

Inflammation from the gout attack can also affect your entire body in the form of a fever, chills, fatigue, and achiness. Once joint fluid is obtained, it is analyzed for uric acid crystals and infection. Your doctor may also do a blood test to measure the amount of uric acid in your blood.

“Strict dietary purine restriction is rarely recommended, as it lowers mean serum urate levels by only about 1 mg/dl, which isn’t enough for most patients,” Dr. Meysemi says. Even though it may seem like nothing is happening, this is the point in which patients should begin long-term treatment. Lowering uric acid levels with medication can prevent future gout flares and long-term complications that go with them. Fortunately, today gout is one of the most treatable forms of arthritis — some rheumatologists say it can be cured. But for too many patients with gout, the disease goes untreated or undertreated.

Sometimes, pain can become triggered by outside events like medication and stress. Most of the differential diagnosis factors with gout can be considered here. Infection is always a major differential, especially in the patient presenting with new acute monoarticular arthritis.

Who's Affected By Gout?

Uricosuric drugs such as probenecid, benzbromarone and sulfinpyrazone decrease URAT1 activity, and consequently UA reabsorption in proximal tubules. On the other hand, drugs such as pyrazinamide, nicotinate and lactate increase urate reabsorption by acting on URAT1, moving UA from the lumen into the tubular cells. They both increase glomerular filtration and tubular reabsorption of UA preventing its loss in urine and increasing UA levels in serum . Deficiency of enzymes involved in purine metabolism leads to overproduction of UA. For example, Lesch-Nyhan syndrome is an inborn error of metabolism resulting from deficiency of an enzyme involved in UA metabolism named hypoxanthine–guanine phosphoribosyltransferase. It is a genetic X-linked recessive disorder with varying degrees of severity according to the type of mutation.

While genetics have left some people predisposed to developing the disease, the resurgence of gout is likely linked to the way Americans live today. There is a lot of speculation that the rising number of gout cases may correlate with America’s obesity epidemic. “Because it occurs in the aging population, as more Americans get older, it makes sense we’re seeing more cases surface,” says Magee.

During a gout attack, modifying your diet may help decrease the length of the flare. Continuing to follow a gout-friendly diet, specifically a low-purine diet, may help prevent the risk of future gout attacks up to five fold. When there are more purines in the body than it can process, uric acid builds up in the bloodstream. Hyperuricemia can cause gout and/or kidney stones in some people, while others have no signs or symptoms at all. When given once daily, allopurinol is effective in reducing the production of uric acid. This is the treatment of choice for patients who have kidney stones from gout and for patients who have kidney problems and/or disease.

Where does Gout usually start?

Gout is a painful form of arthritis. Extra uric acid in your body creates sharp crystals in the joints, leading to swelling and extreme tenderness. Gout usually starts in the big toe but can affect other joints. Gout is a treatable condition, and the uric acid level can be decreased by medication and lifestyle changes.

Untreated gout and elevated SUA levels can lead to permanent joint damage, destruction of tissue, deformities and even loss of normal joint use. Gout has even been connected with other serious health problems, including kidney disease, heart disease, diabetes and stroke. Consequently, gout is widely misunderstood and often understated by the general public – and even by those who suffer from the disease. In fact,just 10 percent of people with gout receive needed, ongoing treatment. This needs to be changed, considering the devastating consequences of untreated gout and elevated serum uric acid levels. Historically, "colchicine" and "Indocin" have been prescribed for acute attacks of gout in the joints.

Role Of Subcutaneous Tophi

Medication — For immediate pain relief, nonsteroidal anti-inflammatory medications or corticosteroids are commonly prescribed. Residual discomfort — When the pain of gout passes, ongoing discomfort can remain and last for a few days or even weeks. Pain — While often focused on the big toe, pain can arise elsewhere, such as in the fingers, wrists, elbows, knees, ankles or heels and often occurs in the night. We have a large armamentarium of treatment options for dealing with heel pain.

Leading A Gout Free Life

Patients should be told that cutaneous side effects may develop during the 2 or 3 first months of treatment and should lead to immediate, life-long, allopurinol cessation. The incidence of these severe skin reactions has been estimated at 0.7 [95%CI0;5–9.9] per 1000 allopurinol initiators-years in the USA , but they are more frequent in Asia, due to more common genetic predisposition . Oral prednisone, at a daily dose of 30 mg/d for 7 days has been shown to be effective , , and is recommended by the ACR and EULAR panels as potential first line therapy in the management of gout flares , . However steroids can worsen hypertension and diabetes and are, in our view, best indicated in patients contra indicated for NSAIDs or colchicine (i.e. CKD patients).

Treatment often consists of both medications for gout and for infection. Immobilization of the foot with a removable cast or the use of crutches is useful. Once the proper medication is prescribed the symptoms of gout will start to subside quite rapidly. Left untreated the clinical course may take several days for the gout attack to subside.

The pain during a gout flare is so excruciating that many visit the emergency room for care. On a typical pain scale, most people with gout will rank their pain as a nine or a 10 – with even the slightest touch causing agony. Besides controlling the terrible pain and inflammation associated with a gout attack, the most important treatment is recognition and treatment of high uric acid levels. “Almost all people with gout will need medication to control their urate,” Dr. Fields says.

The clinical picture of gout is divided into asymptomatic hyperuricemia, acute gouty arthritis, intercritical period, and chronic tophaceous gout. The gold standard of diagnosis is identification of characteristic MSU crystals in the synovial fluid using polarized light microscopy. Imaging modalities include conventional radiography, ultrasonography, conventional CT, Dual-Energy CT, Magnetic Resonance Imaging, nuclear scintigraphy, and positron emission tomography. There is remarkable progress in the application of ultrasonography and Dual-Energy CT which is bound to influence the diagnosis, staging, follow-up, and clinical research in the field. Management of gout includes management of flares, chronic gout and prevention of flares, as well as management of comorbidities.

For those interested in achieving the maximal lowering of uric acid by dietary means, two “Gout Haters Cookbooks” are listed in the “Books about Gout” section below. Special effort should be made to distinguish gout from the other crystal-induced types of arthritis. For example, pseudogout, caused by a different type of crystal , causes the same type of hot, red joint, and the same rapid acceleration of pain as does gout. Pseudogout can be distinguished by seeing calcium deposits within the joints on X-ray, which deposits in a different way than it does in gout. When fluid is examined from an inflamed joint in pseudogout, the specific causative crystal can be seen.

Acute gout most commonly affects the first metatarsal joint of the foot, but other joints are also commonly involved. Definitive diagnosis requires joint aspiration with demonstration of birefringent crystals in the synovial fluid under a polarized light microscope. Treatment includes nonsteroidal anti-inflammatory drugs , colchicine, corticosteroids and analgesics. In patients without complications, NSAID therapy is preferred.
