目前製作 guideline 之目的•台灣地區高尿酸血症的盛行率驚人,尤其施行成人健康體檢後,門診診療中常遇到病人詢問高尿酸血症該如何處理。而目前因無統一的 guideline 可供依循,治療標準不一,常造成醫師及患者的困擾。期待檢視文獻後,能提供有用的資訊,建立使用降尿酸藥物之臨床底線,以為臨床診療之準則。

• Treatment of asymptomatic hyperuricemia is not necessary in most patients, unless perhaps they have very high levels of uric acid or are otherwise at risk of complications, such as those with a personal or strong family history of gout, urolithiasis, or uric acid nephropathy.

• Patients with increased levels of uric acid will usually be treated with drugs if symptoms of acute arthritis or kidney stones occur.

• There is still no consensus on the treatment of individuals with asymptomatic hyperuricaemia.

• Patients with asymptomatic hyperuricemia do not require treatment, but efforts should be made to lower their urate levels by encouraging them to make changes in diet or lifestyle.

Publication Types:          Review

• Drugs for the treatment of acute arthritis attacks include non-steroidal anti-inflammatory drugs (NSAIDs), glucocorticoids systematically or injected into the joint, and colchicine.

• As prophylactic long-term treatment of recurring attacks, allopurinol, probenicide and colchicine are therapeutic alternatives.

• Pittman JR. et al Diagnosis and management of gout. Am Fam Physician 1999 Apr 1;59(7):1799-806, 1810

• Treatment goals (of gout) 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 a

nti-inflammatory agents, colchicine or intra-articular injections of corticosteroids.

• Probenecid, sulfinpyrazone and allopurinol can be used to prevent recurrent attacks.

• Obesity, alcohol intake and certain foods and medications can contribute to hyperuricemia. These potentially exacerbating factors should be identified and modified

• Pollmann G, Kullich W, Klein G. [Therapy of hyperuricemia and gout] Wien Med Wochenschr. 1997;147(16):382-7 Publication Types:          Review

• The therapy of an acute attack of gout primarily is done with non-steroidal antiinflammatory drugs, in rare cases with colchicine or corticoids.

• Gouty arthritis in intermission, independent of the extent of hyperuricemia, as well as chronic gout are indications for an uric acid lowering pharmacotherapy, usually for life.

Bandolier : Allopurinol, oxipurinol, benzbromarone and probenecid for lowering uric acid

• Comment : Not exactly a wealth of information yet. The longer duration study by Bull & Scott implies that maintaining a serum uric acid level below 6 mg/100 mL (350 µmol/L) eventually depletes body stores and gives good relief from acute attacks. The Paulus probenecid study did not appear to show any reduction in attacks without addition of prophylactic colchicine.
