Evaluate the nutritional status, plasma concentration of vitamin E and markers of cardiovascular risk in ataxia telangiectasia (AT) patients.
Cross-sectional study with 13 patients with AT and 22 healthy controls, evaluating the following factors: nutritional status, food intake, lipid profile, plasma concentration of vitamin E, malondialdehyde and high sensitivity C-reactive protein, linking them with atherosclerosis risk in AT patients.
Average age was 14.6 in the AT group, 30.8% were malnourished and 23.1% had stunting. A greater impairment of lean body mass was found in these patients. Concentrations of triglycerides (TG), total cholesterol (CT), LDL-c, non-HDL cholesterol (NHDL-c) were significantly higher in patients and HDL-c, lower. Vitamin E/total lipids and vitamin E/TG ratios were lower in the AT group, and significant inverse correlation between these ratios and NHDL-c, CT/HDL-c, and LDL-c/HDL-c, log TG/HDL-c was observed in the AT group. Alanine aminotransferase correlated directly and significantly with NHDL-c, CT/HDL-c and LDL-c/HDL-c, in patients.
The alterations of lipid metabolism biomarkers suggestive of atherosclerotic risk of male AT patients coupled with lower vitamin E/total lipids ratio and low lean body mass may complicate the clinical course of the disease and emphasizes the importance of multidisciplinary care, routine monitoring of cardiovascular biomarkers and appropriate nutritional guidance.
评估共济失调毛细血管扩张症(AT)患者的营养状况、血浆维生素E浓度及心血管风险标志物。
对13例AT患者和22名健康对照者进行横断面研究,评估以下因素:营养状况、食物摄入量、血脂谱、血浆维生素E浓度、丙二醛和高敏C反应蛋白,并将它们与AT患者的动脉粥样硬化风险联系起来。
AT组平均年龄为14.6岁,30.8%的患者营养不良,23.1%发育迟缓。这些患者的瘦体重受损更严重。患者的甘油三酯(TG)、总胆固醇(CT)、低密度脂蛋白胆固醇(LDL-c)、非高密度脂蛋白胆固醇(NHDL-c)浓度显著更高,而高密度脂蛋白胆固醇(HDL-c)更低。AT组维生素E/总脂质和维生素E/TG比值更低,且在AT组中观察到这些比值与NHDL-c、CT/HDL-c、LDL-c/HDL-c、log TG/HDL-c之间存在显著负相关。患者的丙氨酸转氨酶与NHDL-c、CT/HDL-c和LDL-c/HDL-c直接且显著相关。
提示男性AT患者存在动脉粥样硬化风险的脂质代谢生物标志物改变,再加上较低的维生素E/总脂质比值和低瘦体重,可能使疾病临床过程复杂化,并强调了多学科护理、常规监测心血管生物标志物及适当营养指导的重要性。
