Gout, a common inflammatory arthritis, can be diagnosed with absolute certainty. Gout results from the body's reaction to urate crystals deposited in tissues, and this pathophysiology is well understood. If used appropriately, available therapies can be entirely effective in not only treating the symptoms of gout, but also in eliminating the excess urate from the body, thereby eradicating the disease. Because of these facts, management of patients with gout should be successful. However, management of gout is particularly challenging in the elderly, even though the principles of management are the same for all age groups. The purpose of this article is to review these principles and discuss them as they pertain to the elderly. The classic gout attack is acute in onset, extremely painful and associated with marked swelling, warmth, erythema and tenderness of a single joint. However, the diagnosis of gout may be challenging in the elderly because atypical presentations are more common in this group. Treatment of acute gout involves the use of NSAIDs, colchicine, corticosteroids or corticotropin (adrenocorticotropic hormone). Unfortunately, co-morbid conditions such as chronic kidney disease, peptic ulcer disease and congestive heart failure may make the use of these agents dangerous or contraindicated. Thus, it is important to try to treat an acute flare of gout at the earliest sign, because the sooner treatment is initiated, the faster the inflammation will resolve. Urate-lowering agents include allopurinol and uricosuric agents. These also must be used judiciously in the elderly. However, if used at the lowest dose that maintains the serum urate level below 5.0-6.0 mg/dL, the excess urate in the body will be eliminated, acute flares will no longer occur and tophi will resolve. Gout is often seen in association with hypertension, excessive alcohol consumption, obesity and hypertriglyceridaemia. These conditions and the medications used to treat them may contribute to the hyperuricaemia. Treating these conditions and using medications that do not promote hyperuricaemia will aid in the management of gout. Despite the challenges that often complicate the management of gout in the elderly, an understanding of the pathophysiology of the disease and both the indications and limitations of the medications used should allow successful treatment.
痛风是一种常见的炎性关节炎,诊断相对明确。痛风是机体对沉积在组织中的尿酸盐结晶产生的反应所致,其病理生理学机制已为人熟知。如果使用得当,现有的治疗方法不仅能有效缓解痛风症状,还能清除体内多余的尿酸,从而根治该病。鉴于这些情况,痛风患者的治疗理应成功。然而,即便所有年龄组的治疗原则相同,但痛风在老年人中的治疗仍极具挑战性。本文旨在回顾这些原则,并探讨其在老年患者中的应用。典型的痛风发作起病急骤,疼痛剧烈,伴有单个关节明显肿胀、发热、红斑和压痛。然而,痛风在老年人中的诊断可能颇具挑战,因为非典型表现在该群体中更为常见。急性痛风的治疗包括使用非甾体抗炎药、秋水仙碱、糖皮质激素或促肾上腺皮质激素。遗憾的是,诸如慢性肾病、消化性溃疡病和充血性心力衰竭等合并症可能使使用这些药物变得危险或禁忌。因此,一旦出现痛风急性发作的最早迹象就应尽早治疗,因为治疗开始得越早,炎症消退得就越快。降尿酸药物包括别嘌醇和促尿酸排泄剂。在老年人中使用这些药物也必须谨慎。然而,如果以维持血清尿酸水平低于5.0 - 6.0mg/dL的最低剂量使用,体内多余的尿酸将被清除,急性发作将不再发生,痛风石也会消退。痛风常与高血压、过量饮酒、肥胖和高甘油三酯血症相关。这些情况以及用于治疗它们的药物可能导致高尿酸血症。治疗这些情况并使用不促进高尿酸血症的药物将有助于痛风的管理。尽管老年人痛风管理中常常存在复杂的挑战,但了解该病的病理生理学以及所用药物的适应证和局限性应能实现成功治疗。
