| 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 lipid homeostasis representing elevated risks of cardiometabolic diseases. This study investigated the alteration of plasma lipids/lipoproteins and the underlying regulation mechanism. Materials and Methods: Blood samples were collected from acute myeloid leukaemia (AML) patients preand post-chemotherapy and matched controls. Triglyceride (TG), total cholesterol (TC), high-densitylipoprotein cholesterol (HDL-c), low-density-lipoprotein cholesterol (LDL-c) and apolipoproteins (apo) were quantified in plasma and lipoprotein-density-gradient fractions. The cardiometabolic risks and lipid loads were assessed. Results: Dyslipidaemia was revealed in 75% of AML patients pre-therapy by reduction of HDL-c and in 85% post-therapy by diverse combined patterns. Compared 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 restored post-therapy. The plasma TG concentration was positively correlated with LDL-TG load, whereas plasma TC was positively correlated with HDL-c. Furthermore, the fractionated very-low-density lipoprotein (VLDL)-TG load was lower but LDL-TG load was higher in AML patients than in the controls, suggesting that circulating TG hydrolysis might be impaired from VLDL conversion to LDL. Conclusion: The plasma lipid profiles in AML were aberrant and predicted high cardiometabolic risks, which might need further follow-up attentions. |
