Complications of Candidemia in ICU Patients: Endophthalmitis, Osteomyelitis, Endocarditis

Area of Science:

• Infectious Diseases
• Critical Care Medicine
• Ophthalmology

Background:

• Bloodstream infections caused by Candida species are a significant concern in intensive care units.
• Disseminated candidiasis can lead to secondary infections in various organ systems, including the eyes, bones, and heart.
• The onset of these secondary infections can vary, with some appearing early and others, like vertebral osteomyelitis, diagnosed weeks later.

Purpose of the Study:

• To review the spectrum of secondary infections resulting from candidemia.
• To highlight diagnostic approaches for common complications such as endophthalmitis, osteomyelitis, and endocarditis.
• To discuss current and emerging therapeutic strategies for managing disseminated candidiasis.

Main Methods:

• Literature review focusing on secondary infections following candidemia.
• Discussion of diagnostic modalities including retinal examination, MRI, and TEE.
• Analysis of current antifungal treatment guidelines and emerging therapies.

Main Results:

• Endophthalmitis is a frequent complication requiring early retinal screening post-candidemia.
• Osteomyelitis and endocarditis are less common but serious complications.
• Advanced imaging (MRI, TEE) aids in diagnosing osteomyelitis and endocarditis, respectively.

Conclusions:

• Prompt diagnosis and appropriate antifungal therapy are crucial for managing disseminated candidiasis.
• Newer antifungal agents offer improved tolerability and safety profiles.
• Treatment strategies involve initial broad-spectrum therapy followed by step-down oral azole agents for specific infections.
