Abstract
研究背景與目的:非酒精性脂肪肝疾病 (Non-alcoholic fatty liver disease, NAFLD) 為不過量飲酒者肝臟中脂肪大量堆積。全球盛行率為 25-30%,且日趨嚴重。疾病進展與肥胖、胰島素抗性、血脂異常、血壓異常及發炎反應有關。由於尚無臨床核准用藥,透過飲食與生活型態調整,改善 NAFLD 患者肝臟脂肪變性程度與代謝異常指標,為改善疾病的最有效途徑。咖啡是廣受歡迎的飲品,主要活性成分為咖啡因與綠原酸,具有抗氧化、抗發炎、調節脂質與葡萄糖代謝之益處,對肝臟脂肪變性程度與 NAFLD 相關代謝指標可能具有改善作用。先前統合分析多為探討綠原酸對健康人及各疾病患者之影響,或是分析咖啡攝取量與 NAFLD 盛行率之相關性,對於探討咖啡因與綠原酸對 NAFLD 患者之改善作用及有效劑量方面仍不夠全面。本研究以系統性回顧與統合分析方式,探討咖啡因與綠原酸對於 NAFLD 患者之脂肪變性程度與代謝指標的改善及影響。研究方法:以 PICOs 建立研究問題 (Participants: NAFLD patients; Intervention: coffee, caffeine, chlorogenic acid; Control: placebo; Outcomes: hepatic steatosis status, metabolic parameters; Study design: randomized controlled trials)。利用關鍵字於 PubMed、Embase、Cochrane Library、Scopus、Web of Science 中進行檢索,搜尋年份設定至 2024 年 6 月。將本研究內容於 International Prospective Register of Systematic Reviews (PROSPERO) 上登記註冊 (CRD42023481286)。萃取納入研究之資料,以 Cochrane risk of bias tool (RoB 2) 評估研究品質,以 Rstudio 4.2.3 版進行統合分析。結果:共納入 18 篇研究。結果顯示攝咖啡因與綠原酸顯著改善 NAFLD 患者的肝臟脂肪變性程度 (OR: 7.78; 95% CI: 1.04, 57.93);血脂指標 triglycerides (TG) 顯著降低 23.91 mg/dL (95% CI: -33.89, -13.92);血糖指標 fasting blood sugar (FBS) 顯著降低 4.23 mg/dL (95% CI:-7.46, -1.00);血壓指標 systolic blood pressure (SBP) 顯著降低 2.47 mmHg (95% CI:-4.04, -0.90)、diastolic blood pressure (DBP) 顯著降低 1.04 mmHg (95% CI:-1.56, -0.52)。結論:對於不同疾病進展階段,涵蓋肝臟輕度至嚴重脂肪變性、NASH 及肝臟輕微纖維化之 NAFLD 患者,每日攝取單一成分的 200-500 mg 綠原酸補充劑,或含有 133 mg 綠原酸和 133 mg 咖啡因之雙成分補充劑,或是以混合物形式如苦橙花萃取物、薑黃萃取物、佛手柑萃取物、小檗、油棕萃取物、L-甲硫胺酸、L-谷胱甘肽等混合含有 30-50 mg 綠原酸之補充劑,持續介入八週以上,能夠改善肝臟脂肪變性程度,並且顯著降低血清血脂指標 TG、血糖指標 FBS 及血壓指標 SBP 與 DBP 數值。顯示攝取咖啡因與綠原酸之補充劑能夠改善 NAFLD 患者的疾病進展與代謝指標。
