The role of ascorbic acid in cancer therapy is mainly due to its structural similarity with glucose. When supplemented intravenously in high dose, ascorbic acid can get into the cancer cells and induce apoptosis by causing mitochondrial damage.
The aim was to study the efficacy of high-dose intravenous (IV) ascorbic acid as monotherapy in cancer patients following ketogenic diet and its role in improving the quality of life.
C-reactive protein (CRP) and erythrocyte sedimentation rates (ESRs) were considered as parameters to determine the efficacy of the treatment, and substantial decrease in both the levels was observed within 1-week treatment. CRP levels declined from 3.1946 ± 3.2508 mg/L to 1.0606 ± 0.6706 mg/L (P = 2.27E-10), whereas ESR levels declined from 64.1333 ± 38.8253 mm/h to 31.6 ± 16.5520 mm/h (P = 0.0041). A decline in these parameters shows the association of ascorbic acid in reducing the inflammatory response in cancer. The renal effect of ascorbic acid was also studied by analyzing the creatinine level pre- and postascorbic acid treatment sessions, and it raised from 0.8526 ± 0.22904 to 1.1666 ± 0.2894 mg/dL (P = 1.18E-14). This showed the renal impact of ascorbic acid.
The study highlighted the clinical benefit of IV ascorbic acid in the reduction of inflammatory response in cancer patients. The renal adverse events associated with ascorbic acid alarm the use with caution and therapeutic drug monitoring for ascorbic acid.
抗坏血酸在癌症治疗中的作用主要归因于其与葡萄糖的结构相似性。当静脉内大剂量补充时,抗坏血酸可以进入癌细胞,并通过引起线粒体损伤诱导细胞凋亡。
本研究旨在探讨大剂量静脉内(IV)抗坏血酸作为癌症患者酮饮食后的单一疗法的疗效及其在提高生活质量方面的作用。
C-反应蛋白(CRP)和红细胞沉降率(ESR)被认为是评估治疗效果的参数,在治疗 1 周内,这两个参数均有显著下降。CRP 水平从 3.1946±3.2508mg/L 下降到 1.0606±0.6706mg/L(P=2.27E-10),而 ESR 水平从 64.1333±38.8253mm/h 下降到 31.6±16.5520mm/h(P=0.0041)。这些参数的下降表明抗坏血酸在降低癌症中的炎症反应方面有一定作用。还通过分析抗坏血酸治疗前后的肌酐水平研究了抗坏血酸的肾作用,其从 0.8526±0.22904mg/dL 升高到 1.1666±0.2894mg/dL(P=1.18E-14)。这表明了抗坏血酸对肾脏的影响。
本研究强调了 IV 抗坏血酸在降低癌症患者炎症反应方面的临床益处。抗坏血酸相关的肾脏不良事件提示应谨慎使用,并对抗坏血酸进行治疗药物监测。
