痛風石
痛風石(英語:Tophus)是重型和慢性痛風的標誌,是內含大量單鈉尿酸晶體的慢性肉芽腫樣結構,周圍包裹有炎症細胞和結締組織,多發於尿酸水平控制不佳的痛風患者[1][2][3]。痛風石可影響局部皮膚外觀,嚴重者可導致關節畸形、骨質破壞、皮膚破潰甚至骨折,對患者日常生活和工作造成嚴重影響[4]。其形成受遺傳、生活環境和個人行為等多因素共同作用影響,其形成機制尚未完全明確[3][4]。
研究分析顯示,血尿酸是痛風石形成的危險因素,血尿酸水平越高越易形成痛風石[4]。年齡越大,痛風石形成的風險越高[3],痛風病程較長的患者更易形成痛風石[4][5]。
攝入過多富含嘌呤的食物(如動物內臟、大豆、海產品等)會使血尿酸異常升高增加患痛風的風險[6][7]。合理膳食對於痛風患者病情進展和降低因痛風過早死亡的相關併發症有著重要作用[8]。另有研究顯示以蔬果、低脂乳品攝入等為主的得舒飲食與降低痛風發生風險有關[9]。
