脓毒症泛菌,一种革兰氏阴性杆菌,通常与新生儿重症监护病房的机会性血流感染有关,在免疫功能正常的个体中很少引起肺部感染。我们介绍了一个30岁的男性多灶性空洞性肺炎的病例,双侧肺炎旁积液,和血培养阳性,发生在先前氯胺酮滥用的背景下。病人出现发烧,生产性咳嗽,胸痛,呼吸困难恶化,没有显著的病史或免疫受损的条件。诊断评估显示炎症标志物升高,特征性射线照相发现,静脉抗生素和胸腔引流治疗成功。该病例突出了Pantoeaseptica在肺部感染中的诊断挑战,并表明氯胺酮滥用与对罕见病原体的易感性之间存在潜在联系。需要进一步研究其免疫调节作用。
Pantoea septica, a gram-negative bacillus typically associated with opportunistic bloodstream infections in neonatal intensive care units, rarely causes pulmonary infections in immunocompetent individuals. We present a case of a 30-year-old male with multifocal cavitary pneumonia, bilateral parapneumonic effusions, and positive blood cultures for Pantoea septica, occurring in the setting of prior ketamine abuse. The patient presented with fever, productive cough, chest pain, and worsening dyspnea, without significant medical history or immunocompromising conditions. Diagnostic evaluation revealed elevated inflammatory markers, characteristic radiographic findings, and successful treatment with intravenous antibiotics and pleural drainage. This case highlights the diagnostic challenge posed by Pantoea septica in pulmonary infections and suggests a potential link between ketamine abuse and susceptibility to uncommon pathogens, warranting further investigation into its immunomodulatory effects.
