Abstract

<jats:p>Background: Bacterial endocarditis is a rare infectious entity with a very heterogeneous clinical spectrum; neurological manifestations are the most frequent and serious extracardiac complications of infective endocarditis. However, little is known about the psychiatric manifestations and / or sequels due to septic embolism of the infective endocarditis. Case Report: 50-year-old male, history of arterial hypertension and nephrolithiasis with recurrent urinary tract infections. He began his condition with behavioral changes characterized by marked impulsivity and instability in his interpersonal relationships, adding repetitive events of fever and nephrolithiasis requiring urological interventions and antibiotic therapy. Upon admission assessed by psychiatry because of his impulsive behavior and emotional changes with the presumptive diagnosis of borderline personality disorder. Conclusion: In the following work we describe the first case found in the literature of a psychiatric manifestation in a male patient as the initial complication of a subacute bacterial endocarditis, his diagnostic approach, clinical picture and therapeutic outcome. The early recognition of the clinical picture and the diagnostic approach allowed to establish effective antibiotic treatment; to recognize that bacterial endocarditis might present in a multifaceted way allows to suspect this disease and give treatment opportunely to reduce its burden and mortality. </jats:p>
