摘要
目的:探讨老年肺结核患者血清钙水平的改变与若干因素的关系。方法:对1999年7月～2000年6月住院的年龄大于60岁的患者(共520例)作血清总钙、磷、白蛋白及碱性磷酸酶的定量检测。结果:①老年肺结核患者(405例)组血钙浓度为(2.17±0.19)mmol/L,低血钙总发生率为52.8%,与非结核患者(115例)组血钙浓度(2.24±0.17)mmol/L及低血钙发生率30.4%,两组比较有统计学差异;②肺结核患者血钙水平存在性别差异;与肺结核分型无关;血清白蛋白水平对血钙浓度的影响有统计学意义。结论:肺结核病可影响老年人血钙水平,导致此类患者发生低血钙发生率比同龄其他患者的要高。其与机体的营养状况有直接关系,也可能与内分泌等因素有关。
Objective:To study factors influencing serum total calcium concentration in elderly tuberculosis patients. Methods:520 in patients older than 60 years were included in this study and serum concentration of calcium,phosphate,albumin and alkaline phosphatase were measured by two wavelength color ending immunology assay. Results:1Mean serum concentration of calcium in pulmonary tuberculosis group (PTG) and non tuberculosis group (NTG) was (2.17±0.19) mmol/L and (2.24±0.17) mmol/L respectively. 52.8% patients in PTG (214/405) and 30.4% in NTG were hypocalcaemic (< 2.22 mmol/L). There was significant difference between the two groups (P< 0.05). 2There was variation in calcium concentration among elderly tuberculosis patients. Calcium concentration had no correlation with the types of pulmonary lesion classified by X ray,but was correlated with serum albumin level. Conclusion:Elderly patients with pulmonary tuberculosis have a significant high ratio of hypocalcaemia,which may be associated with nutritional or endocrine disturbances.
