圣乔治教堂诺卡菌引起的肺部感染1例

诺卡菌肺部感染可引起肺诺卡菌病,因其无特异性的临床表现,容易误诊、漏诊。因此,临床实验室的培养鉴定能力非常重要,若不能及时诊治,则会导致病死率较高。诺卡菌病临床较为少见,为引起临床实验室对诺卡菌的鉴定和药敏试验的重视,本文报道了上海市嘉定区中心医院2019年2月收治的1例由圣乔治教堂诺卡菌(Nocardia cyriacigeorgica)感染引起的肺诺卡菌病病例,针对其临床特征、实验室检测及治疗等进行分析,期望对临床诊治诺卡菌病有所帮助。

Spontaneous Nocardiosis With Brain Abscess Caused by Nocardia asteroides in a Cynomolgus Monkey

This paper deals with nocardiosis with brain abscess in a cynomolgus monkey imported from Indonesia. At necropsy, typical abscesses were found in the mandible, lung, kidney, heart, liver, and brain. Nocardia asteroides was isolated as the causative agent. The lesions in the kidney, heart, and brain were considered to be secondary metastases.     

中枢神经系统奴卡菌感染诊治分析附一例鼻疽奴卡菌脑脓肿

目的:了解中枢神经系统(CNS)奴卡菌感染的临床特点、诊治方法及预后。方法:对青岛大学附属医院收治的1例脑奴卡菌感染病例进行报道,并检索相关文献报道的脑奴卡菌感染共31例,对以上32例进行回顾性分析。结果:32例患者中,22例存在基础疾病,18例有糖皮质激素或免疫抑制剂治疗史。主要临床表现为头痛,发热,恶心、呕吐,口齿不清,意识障碍,肢体功能障碍等。7例接受复方磺胺甲噁唑单药治疗,17例接受复方磺胺甲噁唑联合其他抗生素治疗,8例接受喹诺酮类、氨基糖苷类、β-内酰胺类等联合治疗。23例好转或治愈,9例死亡。结论:免疫功能低下是中枢神经系统奴卡菌病的危险因素;奴卡菌培养阳性是确诊该病的惟一方法;应及早应用磺胺类药物,必要时结合外科手术治疗。     

Pacemaker pocket infection by Nocardia carnea. First case description and literature review

Acid-fast gram-positive bacilli are a seldom causal agent of cardiac implantable electronic devices (CIED) infections. A pacemaker pocket infection by Nocardia carnea is presented. The objective of this review is to know the incidence of pacemaker pocket infection by Nocardia and to collect information to contribute to the management of this infection. We describe both our case and those found in the literature. Only three cases were found. Two of the patients were older than 70 years without immunosuppression, presenting erythema at the pacemaker implantation site as main symptom. Bloodstream infection was registered in one of them. Three microorganisms were sensitive to cotrimoxazole. The minimum time of antibiotic therapy was 6 weeks. An incomplete device removal was done in one case, resulting in an unfavorable clinical course. The incidence of pacemaker pocket infection by these microorganisms is low, resolved in most cases with antibiotic treatment and device removal.
