COVID-19 Mortality in Transplant Recipients

Area of Science:

• Transplant medicine
• Infectious diseases
• Public health

Background:

• Organ transplant recipients are immunocompromised and highly susceptible to infections.
• The emergence of SARS-CoV-2 (COVID-19) posed a significant threat to this vulnerable population.
• Previous data on COVID-19 outcomes in transplant patients were limited.

Purpose of the Study:

• To assess the mortality rate of COVID-19 in organ transplant recipients.
• To identify factors associated with mortality in this patient group.

Main Methods:

• A systematic literature review was performed using PubMed and Google Scholar.
• Studies published between January 1, 2020, and May 7, 2020, focusing on COVID-19 in transplant recipients were included.
• Data from 46 articles encompassing 320 transplant patients were analyzed.

Main Results:

• The overall COVID-19 mortality rate among transplant recipients was 20%.
• Mortality varied across different organ transplant types (kidney, liver, heart, lung) and geographical regions.
• Older age, male sex, and pre-existing conditions like hypertension and diabetes were common among deceased patients, with acute respiratory distress syndrome being the most frequent cause of death.

Conclusions:

• Organ transplant recipients experienced a high mortality rate due to COVID-19.
• Outcomes were influenced by country-specific outbreak settings and patient comorbidities.
• Elderly transplant recipients with comorbidities represent a particularly high-risk group for severe COVID-19 outcomes.
