Influenza in solid organ transplant recipients

Area of Science:

• Infectious Diseases
• Transplantation Medicine
• Virology

Background:

• Influenza virus poses a continuous threat to immunocompromised individuals.
• Solid organ transplant recipients are particularly vulnerable to severe influenza complications.
• The 2009 novel influenza A/H1N1 pandemic highlighted increased risks for this population.

Purpose of the Study:

• To review epidemiology, outcomes, prevention, and treatment of influenza in solid organ transplant recipients.
• To evaluate the existing literature on annual influenza strains and the novel influenza A/H1N1 strain.
• To identify strengths and limitations in current research concerning influenza in transplant patients.

Main Methods:

• Systematic literature search of PubMed (July 1980-June 2011).
• Keywords included influenza, transplantation, and specific solid organ types.
• Inclusion criteria: English language, human studies; exclusion criteria: animal/in vitro studies.

Main Results:

• Annual influenza strains present a significant infectious and pathogenic risk to solid organ transplant recipients.
• The novel influenza A/H1N1 strain posed an additional threat, increasing infectious complication risks.
• Vaccination is the primary prevention method; antiviral therapies exist but lack defined dosing for transplant patients.

Conclusions:

• Solid organ transplant recipients have an elevated risk of severe influenza complications.
• Proactive risk identification, illness prevention, and effective treatment are crucial for managing influenza in this population.
