Infections in lung transplanted patients: A review

Area of Science:

• Medical Microbiology
• Transplantation Immunology
• Infectious Diseases

Background:

• Lung transplantation offers improved survival for severe chronic pulmonary disorders.
• Infections pose significant short- and long-term risks, increasing morbidity and mortality post-transplant.

Purpose of the Study:

• To review updated information on factors contributing to infections in lung transplant recipients.
• To summarize current knowledge on bacterial, fungal, and viral infections.
• To outline appropriate therapeutic strategies for post-lung transplant infections.

Main Methods:

• A non-systematic review of literature was conducted.
• Focus on pathogen, host, and environmental factors influencing infection occurrence.
• Analysis of therapeutic options for common infections.

Main Results:

• Bacterial infections constitute approximately 50% of all infections in lung transplant patients.
• Viral infections account for one-third of infections, and invasive fungal infections affect nearly 10% within the first year.
• Pre-transplant comorbidities, surgical disruption of barriers, and nosocomial pathogen exposure are key risk factors.

Conclusions:

• Infections are a major challenge in lung transplantation.
• Empiric antimicrobial therapy, guided by risk factors, local resistance patterns, and drug interactions, can enhance clinical outcomes.
• Comprehensive management strategies are essential for mitigating infection-related complications.
