Infective Endocarditis in Hemodialysis: Descriptive Study

Abstract

Introduction : Infective endocarditis (IE) is a complication associated with high mortality in chronic hemodialysis patients. The aim of our study is to describe the clinical, radiological, microbiological characteristics, and risk factors of mortality in hemodialysis patients with infective endocarditis. Methods : A retrospective study from November 2019 to November 2021 including hemodialysis patients with IE hospitalized in Ibn Sina hospital center in Rabat. Results : Eighteen hemodialysis patients were included. Mean age was 49.5 ± 18 years, sex ratio was 0.8. Catheters were the access sites most commonly used (72.3%). Median duration of hemodialysis was 12 [6; 24] months. Staphylococcus species is major causative bacteria in 60%. The mitral valve was the most commonly affected (44%). Frequent complications including valve insufficiency (50%), septic embolism (66.7%). Four patients underwent surgery and eight died during hospitalization (44.5%). Mitral localization of vegetation was the only factor significantly associated with mortality in our study (P < 0.05). Conclusion : The catheter was the most commonly used access site compared to the arteriovenous fistula. This confirms that it’s the vascular access of choice for his low rate of infectious complication compared to the catheter.
