BACKGROUND

Cardiovascular and infective complications are commonly observed in patients receiving hemodialysis (HD) with cardiovascular events and infection-related complications being the first and second leading causes of death. Infective endocarditis (IE) is characterized by inflammation of the endocardium caused by infection, typically affecting the cardiac valves and can be in acute, subacute, or chronic forms. It is a serious complication within the HD population due to their predisposition for both infection and valvular damage. Considering the frailty and burden of comorbidities in those receiving HD, management of IE in the HD population is very challenging. There has been continuous discussion and debate on optimizing the diagnostic and treatment approach of IE in this patient group to improve their clinical outcomes. Currently, reported outcomes are relatively poor and there are updates from numerous guidelines relating to advances in IE management.

SUMMARY

In this review, we will evaluate the evidence in relation to the epidemiology of HD-associated IE and discuss the important risk factors of IE in patients requiring dialysis. We will also evaluate the current recommendations regarding diagnosis and treatment for suspected or confirmed IE cases amongst HD patients and present the updated data regarding clinical outcomes relating to HD-associated IE.

KEY MESSAGES

The incidence of IE in HD patients is expected to increase going forward as HD becomes more easily accessible alongside an emerging uptake of home HD. A more thorough insight into this topic is required to improve clinical practice relating to IE prevention and management in the HD population, given relatively poor clinical outcomes.
