Clinical syndromes associated with infection can be insidious and difficult to diagnose for multiple reasons. Clinically, can manifest as asymptomatic bacteremia or with subtle subacute constitutional symptoms. Second, it is a fastidious organism that is difficult to identify using traditional culture methods. Last, the body lice vector of transmission is likely not uncommon in most patients affected, who are homeless and of low socioeconomic status. Therefore, barriers in seeking medical care and financial constraints for medications are important considerations. The mainstay of literature surrounding endocarditis is from Europe and the developing nations. Herein, we describe a case of native valve endocarditis secondary to in a homeless male with preexisting valvular disease and undertake a comprehensive literature review of documented endocarditis in North America.
感染相关的临床综合征可能由于多种原因而隐匿且难以诊断。临床上,可能表现为无症状菌血症或轻微的亚急性全身症状。其次,它是一种难以用传统培养方法识别的苛刻生物体。最后,体虱传播的载体在大多数受影响的患者中可能并不少见,这些患者无家可归且社会经济地位较低。因此,寻求医疗和药物的经济限制是重要的考虑因素。文献中围绕感染性心内膜炎的主要内容来自欧洲和发展中国家。在此,我们描述了一例由无家可归的男性体内的引起的自身瓣膜心内膜炎,该患者存在先前的瓣膜疾病,并对北美的已发表的感染性心内膜炎病例进行了全面的文献复习。
