Understanding Gout: Incidence and Treatment Insights
Gout, often termed the "rich man's disease," has been increasingly making headlines in recent years. Today, let's dive deep into this condition to uncover its mysteries.
I. What is Gout?
Gout is a metabolic disorder primarily caused by purine metabolism dysfunction and/or impaired uric acid excretion. When uric acid production exceeds excretion, blood uric acid levels rise persistently. Urate crystals then deposit in joints and surrounding tissues, triggering acute or chronic inflammation, which leads to swollen, hot, and painful joints, severely affecting the patient's quality of life.
II. How Prevalent is Gout?
Gout's incidence is rising globally, including in China. Currently, the prevalence of gout in China is approximately 1%–3%, with a higher rate in men than women. In economically developed regions or among specific populations—such as those with long-term high-purine diets, alcohol abuse, obesity, or metabolic syndrome—the incidence is even higher. This means 1–3 out of every 100 people may be suffering from gout. It is no longer a rare disease but a hidden health threat around us.
III. How Do Western Medications Treat Gout?
(1) Acute Attack Phase: Rapid Pain Relief
When a gout attack strikes, immediate pain relief is critical. Non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and diclofenac sodium, reduce pain and inflammation by inhibiting inflammatory mediators. Colchicine is another common choice, controlling inflammation by suppressing white blood cell chemotaxis. When these drugs are ineffective or contraindicated, glucocorticoids like prednisone may be used, which can quickly relieve symptoms but carry more side effects with long-term use.
(2) Intermittent and Chronic Phases: Sustained Uric Acid Reduction
To prevent recurrent attacks, uric acid levels must be consistently lowered during the intermittent and chronic phases. Allopurinol, a classic uric acid-lowering drug, reduces uric acid production by inhibiting xanthine oxidase. Febuxostat, similar in mechanism to allopurinol, may offer better efficacy with relatively fewer side effects. Benzbromarone, alternatively, lowers blood uric acid by promoting renal uric acid excretion.
IV. Does Gout Require Surgery?
In most cases, gout is managed with medications, but surgery may be necessary for severe cases. Surgical removal of tophi is indicated when they are large enough to impair joint function, compress nerves, or become infected and ulcerated. For patients with severely damaged or deformed joints, joint replacement surgery may help restore function.
V. Are There "Magic Bullet" Drugs for Gout?
Febuxostat is a widely recognized uric acid-lowering drug, offering effective尿酸 control with fewer side effects than traditional drugs like allopurinol. During acute attacks, low-dose colchicine combined with NSAIDs can control symptoms effectively while minimizing side effects. Newer drugs like pegloticase also show promising efficacy and safety in clinical use, though they tend to be more expensive.
It's crucial to emphasize that gout treatment is highly individualized. Every patient should work with a healthcare provider to select the most suitable medications and treatment plan, alongside regular monitoring of uric acid levels and related indicators, to better manage the condition.
