Nocardia is an opportunist bacteria involved in patients with cellular immunodepression or chronic lung disease. The most frequent portals of entry are the respiratory tract by inhalation or direct inoculation through a cutaneous effraction. Nocardiosis may be localised or disseminated.
We report a rare case of disseminated nocardiosis to Nocardia nova with pulmonary, cutaneous, cerebral attacks and femoral osteomyelitis. The diagnosis was confirmed by prolonged cultures of the bronchoalveolar fluid and the pus extracted from a cutaneous lesion. The outcome was favorable under adapted and prolonged antibiotherapy with imipenem and amikacine and then cotrimoxazole.
This observation is original because it involves a immunocompetent patient with an association of two exceptional locations for N. nova: brain abscesses and femoral osteomyelitis. Screening for cerebral involvement should be systematic, even in the lack of neurological signs. An adapted and prolonged antibiotherapy must be conducted.
诺卡菌是一种机会致病菌,可感染细胞免疫功能低下或患有慢性肺部疾病的患者。最常见的感染途径是通过吸入进入呼吸道或经皮肤破损处直接接种。诺卡菌病可局限或播散。
我们报告一例罕见的播散性新星诺卡菌病,累及肺部、皮肤、脑部并伴有股骨骨髓炎。通过对支气管肺泡灌洗液和从皮肤病变处抽取的脓液进行长时间培养,确诊了该病例。在使用亚胺培南和阿米卡星进行适当且延长疗程的抗菌治疗,随后使用复方新诺明治疗后,病情转归良好。
该病例具有独特性,因为它涉及一名免疫功能正常的患者,新星诺卡菌出现了两个罕见的感染部位:脑脓肿和股骨骨髓炎。即使没有神经系统体征,也应系统地筛查脑部受累情况。必须进行适当且延长疗程的抗菌治疗。
