Infections in solid organ transplant recipients

Area of Science:

• Infectious diseases
• Microbiology
• Transplantation immunology

Background:

• Antimicrobial-resistant Gram-positive bacteria, such as enterococci and staphylococci, are increasingly prevalent in transplant centers.
• These resistant pathogens pose a formidable challenge to transplant recipients, impacting patient outcomes.
• Recent studies highlight the clinical significance of various infections in this vulnerable population.

Purpose of the Study:

• To summarize the current challenges posed by resistant bacteria and emerging viral infections in organ transplant recipients.
• To underscore the importance of monitoring and managing these pathogens in the context of transplantation.

Main Methods:

• Literature review of recent publications (within the past year) focusing on infections in transplant recipients.
• Analysis of reported trends in antimicrobial resistance and viral pathogen emergence.

Main Results:

• Resistant Gram-positive bacteria (enterococci, staphylococci) are leading pathogens in transplant centers.
• Human herpesvirus-6 (HHV-6) has demonstrated clinical relevance post-transplantation.
• Human herpesvirus-8 (HHV-8) transmission via allografts can lead to Kaposi's sarcoma.
• A novel hepatitis virus has been identified, with ongoing research into its role in transplantation.

Conclusions:

• Transplant recipients face a dual threat from multidrug-resistant bacteria and newly identified or re-emerging viruses.
• Vigilance and further research are crucial to address the evolving infectious disease landscape in transplantation.
