腹部外科感染合并营养不良患者的C-反应性蛋白

Detection of C-reactive protein in abdominal infection patients with malnutrition

检测149例腹部外科患者血清C-反应性蛋白。根据感染定义患者分成感染组和非感染织，再根据营养危险指数≤97．5和＞97.5分成合并和不合并营养不良亚组。结果显示，在感染合并营养不良与感染不合并营养不良亚组之间和非感染合并营养不良与非感染不合并营养不良亚组之间，C-反应性蛋白水平比较无显著性差异（均P＞0．05）。表明腹部外科感染合并营养不良患者的C-反应性蛋白产生未受到影响，其血清C-反应性蛋白水平仍可作为判断炎症存在及严重程度的非特异性指标。

Serum C-reactive protein levels in 149 abdominal surgical patients were detected. The patients were divided into the infected and uninfected groups according to the definition of the infection.Each group was subdivided into malnourished and well-nourished subgroups in accordance with the Nutritional Risk Index (NRI > 97. 5 well-nourished and ≤97. 5 malnourished). There was no sinificant difference in C-reactive protein levels between two subgroups in infected and uninfected groups (P > 0.05). The results suggested that C-reactive protein production was not interfered with by malnutrition in abdominal infection patients. The serum levels of the C-reactive protein could be used to detemine the existance of the infection and the degree of the infection.
