目的:了解2014年至2015年获得性免疫缺陷综合征(AIDS)住院患者痰培养的致病菌分布特点,为临床判断肺部感染的性质及合理选用抗菌药物提供依据。方法:对住院AIDS患者中疑似肺部感染的471例患者常规留取痰标本,并进行细菌、真菌及分枝杆菌培养,对其中痰培养阳性的患者进行统计学分析。结果:471例患者痰培养中检测出45种病原菌,共659例次,其中普通细菌113例次(17.1%)、真菌413例次(62.7%)、分枝杆菌133例次(20.2%)。普通细菌中革兰阴性菌共82例次(82/113,72.6%),排名前3位的分别是鲍曼不动杆菌(16例次)、肺炎克雷伯杆菌(14例次)及铜绿假单胞菌(14例次)。革兰阳性菌共31例次(31/113,27.4%),排名前3位的分别是凝固酶阴性葡萄球菌(19例次)、金黄色葡萄球菌(9例次)及肠球菌属(2例次)。真菌中排名前3位的分别是白假丝酵母菌(316例次)、其他假丝酵母菌(62例次)及曲霉菌(14例次)。分枝杆菌中非结核分枝杆菌69例次、结核分枝杆菌53例次、未分型者11例次。471例患者中349例痰培养测出1种病原菌,122例可检测出2种以上的病原菌,经χ~2检验分析,CD4≤100个/μL的患者较CD4>100个/μL的患者痰中更容易检测出2种以上的致病菌(P=0.008)。结论:AIDS患者痰培养中致病菌种类繁多,且容易发生混合感染,尤其在CD4低下的患者中。 相似文献

Objective To study the relationship of serum visfatin level and coronary heart disease (CHD). Methods Eighty eight hospitalized patients were enrolled into the study and divided into CHD group(n = 62) and non-CHD control group(n = 26) according to the angiography results; the CHD group was further divided into single-, double-, multi-vessel affected groups. The serum level of visfatin was measured by ELISA,the lesion severity of coronary arteries was assessed by Gensini coronary scoring system, and the correlation between serum visfatin level and coronary lesion severity was evaluated statistically. Results The level of serum visfatin was significantly higher in CHD group than the control group([ 10. 77 ± 2. 63 ] μg/L vs. [ 7. 13 ± 2. 06 ]μg/L,P < 0. 05). The visfatin level increased along with the the number of stenosis vessels(P < 0. 05). The sermn visfatin levels of no stenosis, single-, double-, multi-vessel groups were(7. 13 ± 2. 06) μg/L,(9. 30±2. 19) μg/L,(10. 81 ± 2. 12) μg/L,(12. 79 ± 2. 20) μg/L respectively. A significant positive correlation was found between coronary lesion severity score and serum visfatin level(r = 0. 483, P < 0. 01). Conclusion The visfatin may be directly related to the initiation and development of coronary diseases. The higher level of serum visfatin was, the more severe coronary artery disease would be. 相似文献

目的 分析艾滋病合并隐球菌血流感染患者的临床特征及治疗效果,同时分析预后的影响因素。方法回顾性收集上海市公共卫生临床中心2015-2020年艾滋病合并隐球菌血流感染患者的临床特征、实验室检查及预后资料。按照出院结局分为治疗好转组和预后不良组,用t检验、秩和检验及χ2检验比较两组患者的人口学及临床特征,多因素Logistic回归模型分析不良预后的影响因素。结果 93例纳入分析的患者中66例(70.97%)治疗好转,27例(29.03%)预后不良,平均年龄(38.95±10.76)岁,CD4细胞中位数为16(9,29)个/μL。89.25%(83人)的患者合并有隐球菌性脑膜炎,中性粒细胞>4×109/L的患者预后不良的比例(40.00%)更高。培养阳性时间<7天(OR=3.73,P=0.007)及有精神症状(OR=4.23,P=0.013)是预后不良的危险因素。结论 艾滋病合并隐球菌血流感染的患者伴有隐球菌性脑膜炎的比例较高。对于隐球菌培养阳性时间少于7天和有精神症状的艾滋病合并隐球菌血流感染患者,在临床上要更多的关注,更积极地采取相... 相似文献

目的 探讨在艾滋病人群中不同剂量两性霉素B诱导治疗隐球菌脑膜炎的安全性及有效性,为优化艾滋病相关性隐球菌脑膜炎的诊疗提供参考。方法 收集2019年1月—2022年3月入住上海市公共卫生临床中心明确诊断为艾滋病相关性隐球菌脑膜炎患者,根据两性霉素B使用剂量分为标准剂量组和低剂量组,收集治疗前后临床检测结果、临床预后以及药物不良反应进行回顾性分析。结果 共入组57例患者,其中标准剂量组(0.7 mg·kg-1·d-1)25例,低剂量组(0.4~0.5mg·kg-1·d-1)32例,两组患者3级以上药物不良反应发生率相似(P=0.186),主要包括低钾血症、贫血、肝功能异常、中性粒细胞减少、血小板减少。标准剂量两性霉素B可以显著缩短脑脊液隐球菌培养转阴时间(P<0.001)。两组患者的住院时间(P=0.921)及90 d病死率(P=0.717)差异无统计学意义。结论 该院收治的艾滋病人群中使用标准剂量两性霉素B诱导治疗隐球菌脑膜炎可以有效加快脑脊液中隐球菌培养转阴时间,且不会增加严重不良反应的发生率... 相似文献

目的 探讨血清内脂素水平与冠心病的关系.方法 88例住院患者,根据冠状动脉造影的结果分为冠心病组(62例)及对照组(26例),其中冠心病组分为单支病变组、双支病变组、多支病变组,采用ELISA法测定内脂素.同时记录冠心病患者Gensini冠脉病变积分,并与血清内脂素进行相关性分析.结果 冠心病组患者血清内脂素明显高于对照组[(10.77±2.63)μg/L与(7.13±2.06)μg/L,t=-6.283,P<0.01].内脂素随冠状动脉病变支数的增加而升高(P<0.05).冠状动脉造影正常、单支病变、双支病变、多支病变的患者,其血清中内脂素水平分别为(7.13±2.06)、(9.30±2.19)、(10.81±2.12)、(12.79±2.20)μg/L.血清内脂素与Gensini冠脉病变积分呈显著正相关(r=0.483,P<0.01).结论 内脂素升高与冠心病密切相关,内脂素浓度越高,冠状动脉病变越严重.Abstract: Objective To study the relationship of serum visfatin level and coronary heart disease (CHD).
