Abstract
緒論
冠狀動脈疾病(coronary artery disease)為冠狀動脈因狹窄或阻塞所致,近年來已有研究指出冠狀動脈疾病與痛風有關。然而,目前關於降尿酸藥物治療能否用以預防冠狀動脈疾病,相關研究仍不甚充足,故本研究欲針對服用異嘌呤醇(allopurinol)及苯溴香豆酮(benzbromarone)之痛風患者,初步觀察其罹患冠狀動脈疾病之風險變化,並進一步分析藥物累積劑量多寡,是否和冠狀動脈疾病之罹病風險有關。
研究方法
本研究為一回溯性世代研究,自臺灣全民健康保險研究資料庫所提供之承保抽樣歸人檔中,選出二○○一年至二○○八年間診斷為痛風者,並將有冠狀動脈疾病、心衰竭、慢性腎臟病、癌症及痛風病史者,以及在痛風確診前曾服用異嘌呤醇或苯溴香豆酮者予以除卻。上述各疾病須經醫師開立兩次以上門診診斷,或一次以上住院診斷,方視為確診;而藥物處方開立即視為服藥。痛風病患依降尿酸藥物之用藥選擇,分為A組(異嘌呤醇單用)、B組(苯溴香豆酮單用)、A+B組(兩藥兼用)三組,並排除二○○九年後始服用異嘌呤醇或苯溴香豆酮者,以確保病患至久可追蹤三年。為確立上述兩降尿酸藥物預防冠狀動脈疾病之時序關係,本研究亦剔除服藥前即罹病、服藥後一百八十日內即罹病,或服藥起一百八十日內服藥天數未及九十日者,共得8,227名實驗組病患。其中A組1,437名、B組4,241名,和A+B組2,549名病人,分別依性別及年齡以一比一配對未曾服用異嘌呤醇或苯溴香豆酮之痛風病人,得8,227名對照組(C組)病人。實驗組以異嘌呤醇或苯溴香豆酮初次開立日期為觀察起始日(index date),對照組則以痛風確診日期為觀察起始日;各組配對追蹤迄任一病人發生冠狀動脈疾病止,或屆三年追蹤期滿。
研究結果
整體而言,共變數(covariate)經校正後,不論病人單用異嘌呤醇、單用苯溴香豆酮,抑或兩藥兼用,罹患冠狀動脈疾病之風險在統計學上與對照組之罹病風險均無二致。然而,若進一步分析藥物累積劑量對冠狀動脈疾病罹病風險之影響,則發現三組實驗組病人經服用三百六十個定義每日劑量(defined daily dose, DDD)後,冠狀動脈疾病之罹病風險皆明顯較對照組低;其中,又以單用異嘌呤醇之病患之罹病風險最低。此外,A組及A+B組服用藥物之累積劑量與冠狀動脈疾病之罹病風險成線性關係,其斜率為負。
結論
雖整體而言病人服用異嘌呤醇或苯溴香豆酮後,冠狀動脈疾病之罹病風險在統計學上並無異於對照組;然一旦藥物累積達一定劑量,各實驗組皆顯示罹病風險較對照組顯著下降。是故,筆者認為異嘌呤醇和苯溴香豆酮或許可用以輔助預防冠狀動脈疾病之發生,但本研究結果猶亟待後續研究予以佐證。
