Gout

Gout is a prevalent and painful form of arthritis, marked by joint inflammation due to uric acid crystal accumulation. It manifests as a sudden onset of severe pain, swelling, and warmth in one or more joints, often turning into a disabling condition if untreated. In the U.S., about 2% to 6% of adults suffer from gout, and its incidence has risen in the past twenty years, mainly due to obesity and the adoption of a "western diet" rich in fats, sugars, and salts. Historically called the "disease of kings" because it was associated with indulgence in rich foods and alcohol, gout now affects a broad demographic, as its risk factors extend beyond diet. The good news is that gout is highly treatable compared to other arthritic conditions.

Causes

Gout results from the build-up of uric acid crystals in the joints, initiating an inflammatory response. Uric acid, a byproduct of purine metabolism, should be excreted by the kidneys, but an aging body can struggle to eliminate it, leading to increased blood levels. Risk factors for gout include:

• Non-modifiable risk factors:

• Age: Greater risk in those over 65 but possible in younger individuals.

• Sex: Men are more susceptible than women; however, post-menopausal women experience heightened risk.

• Family history: A first-degree relative with gout raises personal risk.

• Modifiable risk factors:

• Medical conditions: Conditions such as chronic kidney disease, hypertension, and Type 2 diabetes escalate uric acid levels.

• Medications: Diuretics like Hydrochlorothiazide and Furosemide can raise uric acid levels.

• Diet: Foods high in purines and high-fructose corn syrup, alongside alcohol, can elevate uric acid levels.

While some factors like age and family history are unavoidable, dietary and lifestyle adjustments can help mitigate risk.

Symptoms

Gout commonly begins with an unexpected, severe attack. Typical symptoms include:

• Joint Pain: Severe pain typically in the big toe or knee joints but can affect any joint, especially fingers in women.

• Swelling: Noticeable swelling of the affected joint.

• Redness and Warmth: Reddish appearance and warmth over the joint.

• Tenderness: Extreme sensitivity, making touch and pressure unbearable.

• Difficulty Using the Joint: Trouble bearing weight or functioning normally with the affected joint.

Some may experience a fever during attacks, potentially indicating septic arthritis, which requires immediate medical attention. Initial gout episodes typically resolve in one to two weeks, yet chronic gout can lead to persistent symptoms and complications like:

• Tophi: Uric acid deposits visible as chalky lumps under the skin.

• Joint Erosions: Progressive joint and bone damage over time.

Proper management is essential to prevent long-term damage and maintain joint function.

Diagnosis

To diagnose gout, healthcare providers may perform a joint aspiration, where fluid is extracted from the affected joint and examined for uric acid crystals under a microscope. Alternatively, diagnosis can rely on symptoms such as pain in the big toe joint, known risk factors, high uric acid levels, and observable tophi. If treatments fail to improve symptoms, joint aspiration may be used to rule out other arthritis types. Initial gout episodes may require an X-ray to exclude other causes of joint pain. Typically, a primary care provider can diagnose and treat gout, though severe cases may need a rheumatologist's expertise.

Medications

Gout is effectively managed through medications, crucial for handling acute and chronic symptoms.

• Acute Gout Attack Treatment:

• Prompt medication at attack onset is vital.

• Common drugs include Colchicine, NSAIDs like Indomethacin or Naproxen (Aleve), and steroids such as Prednisone. Steroid injections into the joint may also be administered.

• Long-term Gout Management:

• For recurrent attacks or in cases with tophi or joint damage, long-term medications are used to lower uric acid levels, such as:

• Allopurinol (Zyloprim)

• Febuxostat (Uloric)

• Probenecid (usually a secondary option)

• Regular monitoring every 2 to 6 weeks during initial treatment ensures uric acid levels stay below 6.0 mg/dL. Until control is achieved, additional medications like colchicine or NSAIDs may be included to prevent future attacks.

Living

Managing gout involves tackling occasional debilitating flare-ups to prevent long-term joint damage. With medication, gout control is achievable. While newer research indicates dietary changes are not paramount, reducing alcohol, red meat, shellfish, and high-fructose foods intake aids prevention. Keeping a healthy weight also lowers flare risk. Many gout patients require lifelong medication, a commitment made easier by understanding the alternative involves severe pain. Adherence to prescribed therapy can significantly impact lifestyle quality, reducing symptoms and enabling more activity.
