Klebsiella oxytocatricuspid valve endocarditis in an elderly patient without known predisposing factors

Abstract

A 73-year-old man with history of nephrolithiasis was admitted after a witnessed cardiac arrest. In the emergency department, the patient had several runs of ventricular fibrillation treated with defibrillation and amiodarone infusion. Echocardiography revealed reduced ejection fraction with multiple mobile structures attached to the tricuspid valve leaflets. Due to concern for possible endocarditis, the patient was started on broad-spectrum antibiotics. On the following day, a renal ultrasound was performed for acute kidney injury followed by a non-contrast CT scan that revealed an obstructing 21 mm left-sided ureteral stone with pyohydronephrosis. He underwent emergent nephrostomy tube placement. Blood and urine cultures subsequently demonstrated the growth of A follow-up transoesophageal echocardiogram confirmed multiple mobile, hyperechoic masses consistent with vegetations. The suspected source for the endocarditis was from the pyelonephritis. The patient's clinical condition improved after a course of intravenous antibiotics and was discharged on oral antibiotics.

Antimicrobial resistance of bacterial strains in patients undergoing orthodontic treatment with and without fixed appliances

“…A strain of Granulicatella adiacens was also isolated, commonly found in the mouth and associated with some cases of endocarditis. 27 Klebsiella oxytoca is an important bacterial isolate related to the cause of hospital-acquired infection in adults, causing bacterial endocarditis and having multiple resistance to commonly used antimicrobials 28 ; two strains were found to be resistant to ampicillin. A strain of Pseudomonas aeruginosa was isolated, known as the main cause of morbidity and mortality in patients with cystic fibrosis and one of the main causes of nosocomial infections.…”
