Recently, the adductor pollicis muscle thickness (APMT) has been suggested as a new nutritional marker in several population.
In view of the scarce data regarding the use of this marker in CKD patients, we aimed to evaluate APMT and its association with nutritional parameters in patients on hemodialysis.
We evaluated 73 hemodialysis patients (52.3 ± 17 years, without residual renal function). The APMT was assessed in the non vascular access arm by means of skinfold caliper. Body composition (bioelectrical impedance), handgrip strength (HGS, dynamometer), nutritional status (subjective global assessment), and laboratory parameters (creatinine, total protein and albumin) were also evaluated.
Subjects with APMT values above the median were in greater proportion black/ brown, younger and had higher HGS. The APMT correlated positively with HGS, albumin and body cell mass (%), and negatively with age. In the linear regression analysis adjusted for sex, age and length on hemodialysis, APMT was independently associated with HGS.
APMT was able to predict HGS in hemodialysis patients, suggesting APMT as a promising nutritional marker in this population.
最近，拇收肌厚度（APMT）已被提议作为多人群中的一种新的营养指标。
鉴于关于该指标在慢性肾脏病（CKD）患者中应用的数据稀缺，我们旨在评估血液透析患者的APMT及其与营养参数的关联。
我们评估了73例血液透析患者（年龄52.3±17岁，无残余肾功能）。通过皮褶卡尺在非血管通路侧手臂评估APMT。还评估了身体成分（生物电阻抗法）、握力（HGS，握力计）、营养状况（主观全面评定法）以及实验室参数（肌酐、总蛋白和白蛋白）。
APMT值高于中位数的受试者中，黑人/棕色人种比例更高、年龄更小且握力更高。APMT与握力、白蛋白和体细胞质量（%）呈正相关，与年龄呈负相关。在对性别、年龄和血液透析时长进行校正的线性回归分析中，APMT与握力独立相关。
APMT能够预测血液透析患者的握力，提示APMT是该人群中有前景的营养指标。
