[摘要] 目的 分析乳腺癌化疗后粒细胞减少伴发热(FN)合并感染的临床特点及降钙素原在FN合并感染患者中的诊断价值。 方法 选取2015年10月~2017年8月乳腺癌化疗后粒细胞减少伴发热(FN)合并感染的患者20例为观察组,另外选择非感染患者20例为对照组,分析乳腺癌化疗后粒细胞减少伴发热(FN)合并感染的临床特点,分别测定两组降钙素原的水平并进行比较。 结果 分析乳腺癌化疗后粒细胞减少伴发热(FN)合并感染的部位包括呼吸道、泌尿道和消化道,导致感染的病原菌包括大肠埃希菌、金黄色葡萄球菌和肺炎克雷伯杆菌。观察组的降钙素原水平明显高于对照组,差异有统计学的意义(P /6/view-10764429.htm

[Abstract] Objective To analyze the clinical characteristics of granulocytopenia complicated with fever (FN) concurrent infection after breast cancer chemotherapy and the diagnostic value of procalcitonin in the patients with FN concurrent infection. Methods 20 patients with granulocytopenia complicated with fever (FN) concurrent infection after breast cancer chemotherapy from October 2015 to August 2017 were selected as the observation group, and another 20 patients without infections were selected as the control group. The clinical characteristics of granulocytopenia complicated with fever (FN) concurrent infection after breast cancer chemotherapy was analyzed, and the levels of procalcitonin were measured and compared between the two groups. Results The part of granulocytopenia complicated with fever (FN) concurrent infection after breast cancer chemotherapy was analyzed, including the respiratory tract,urinary tract and digestive tract. The pathogens leading to infection was analyzed, including escherichia coli, staphylococcus aureus and Klebsiella pneumoniae.The level of procalcitonin in the observation group was significantly higher than that in the control group, and the difference was statistically significant(P 1 资料与方法
1.1 一般资料
选择2015年10月~2017年8月乳腺癌化疗后粒细胞减少伴发热(FN)合并感染的患者20例为观察组,另外选择非感染患者20例为对照组。观察组中患者表现为发热、头晕、头痛等症状,经临床诊断为粒细胞减少伴发热,经血常规等检查存在感染,对照组中患者无感染出现,但是存在一定程度的发热,排除存在严重感染性疾病、原发性细胞减少的患者。观察组中男9例,女11例,年龄34~68岁,平均(48.7±3.1)岁,对照组中男8例,女12例,年龄为32~69岁,平均(49.2±2.5)岁。两组一般资料之间比较,差异无统计学意义(P>0.05),具有可比性。
1.2 方法
两组患者在乳腺癌的治疗中应用常规的化疗方案进行治疗,化疗方案采用“EC-T”3周方案进行化疗,在化疗期间对血常规进行监测,患者在出现发热的6 h以内采集静脉血,经离心后分离取上清液,待分析。对观察组中的合并感染的患者的血样进行培养,存在呼吸道感染者同时需要进行痰液培养,存在消化道感染者同时需要进行尿液和粪便的培养。分别测定两组患者的血清降钙素原的量,以免疫化学发光法进行定量测定,记录两组血清降钙素原的测定结果并进行比较分析。
1.3 评价标准[7]
患者的口腔温度不低于38.3℃持续1 h以上时为发热,血清降钙素原的浓度>0.5 ng/mL时为感染阳性。
1.4 统计学分析
应用统计学软件SPSS18.0资料进行分析,计量资料用均数±标准差(x±s)表示,组间比较采用t检验;计数资料用百分比表示,采取χ2检验,P [参考文献]
