中文摘要
血液惡性腫瘤影響脂質代謝平衡,導致心臟代謝疾病的風險升高。本研究目的為分析白血病患者治療過程血漿中脂質/脂蛋白的變化,及其潛在的調節機制與疾病的相關性。檢體來源為急性骨髓性白血病(AML)患者化療前後與健康對照組的血液樣本。本研究利用超高速密度梯度離心法分離脂蛋白,通過分析血漿三酸甘油脂(TG)、總膽固醇(TC)、高密度脂蛋白膽固醇(HDL-c)、低密度脂蛋白膽固醇(LDL-c)和載脂蛋白(apo),進行心臟代謝疾病風險評估和脂質恆定測試。分析結果顯示,在治療前,75%的AML患者呈現血脂異常,主要為HDL-c降低;而治療後,則有85% AML患者血脂異常並出現多樣組合模式。與健康對照組相比較,AML患者在治療前和治療後,TG與心血管代謝疾病的風險皆有升高的表現。同時,總膽固醇、高密度脂蛋白膽固醇、載脂蛋白apoAI、載脂蛋白B-100、載脂蛋白CIII和載脂蛋白J在治療前顯著降低,治療後與健康對照組則是沒有顯著差異。相關性分析結果顯示,血漿TG濃度與低密度脂蛋白TG含量,而血漿TC濃度與HDL-c出現正相關。此外,與健康對照組相比,AML患者的極低密度脂蛋白(VLDL)-TG負荷較低,但LDL-TG負荷較高,暗示在VLDL轉化為LDL的過程中TG水解可能受損。本研究結果顯示急性骨髓性白血病患者血液脂質代謝發生異常,可能增加併發心臟代謝疾病的風險,因此需要長期追蹤治療後病人的後續發展。
英文摘要
Background: Haematological malignancy affects lip id homeostasis representing elevated risks of cardiometabolic diseases. This study investigated the alteration of plasma lipids/lipoproteins and the underlying regulation mec hanism. Materials and Methods: B lood samples were collected fr om acute myeloid leukaemia(AML)patients pre- and post-chemotherapy and matched controls. Trigly ceride(TG), total cholesterol(TC), high-density-lipoprotein cholesterol(HDL-c), low-density-lipoprotein cholesterol(LDL-c)and apolipoproteins(apo)were quantified in plasma and lipoprotein-density-gradient f ractions. The cardiometabolic risks and lipid loads were assessed. Results: Dyslipidaemia was revealed in 75% of AML p atients pre-therapy by reduction of HDL-c and in 85% post-therapy by div erse combined patterns. Com pared to the controls, AML patients exhibited increased plasma TG and cardiometabolic risks both pre - and post-therapy. The plasma TC, HDL-c, apoAI, B-100, CIII and J were decreased pre-therapy but were re stored post-therapy. The plasma TG concentration was positively correlated with LDL-TG load, whereas plasma TC was positively correlated with HDL-c. Furthermore, the fractio nated very-low-density lipoprot ein(VLDL)-TG load was lower but LDL-TG load was higher in AML pat ients than in the controls, sug gesting that circulating TG hydrolysis might be impaired from VLDL conv ersion to LDL. Conclusion: The plasma lipid profiles in AML were a berrant and predicted high cardiometabolic risks, which might need further follow-up attentions.
