Abstract
BACKGROUND: The effect of solid organ transplantation (SOT) on the severity and mortality of coronavirus disease 2019 (COVID-19) remained controversial. There is still no consensus on whether solid organ transplantation (SOT) recipients with COVID-19 are at greater risk of developing severe or fatal COVID-19. Therefore, we conducted a systematic review and meta-analysis to investigate the association between SOT, severe COVID-19 illness, and mortality. METHODS: A systemically comprehensive search in Pubmed, Embase, the Cochrane Library, Web of Science, and China National Knowledge Infrastructure was performed for relevant studies and articles. Consequently, we pooled the odds ratio (OR) from individual studies and performed heterogeneity, quality assessment and subgroup/sensitivity analysis. RESULTS: A total number of 15 articles with 265,839 participants were included in this study. Among the total number of participants, 1485 were SOT recipients. The meta-analysis results showed that transplant patients with COVID-19 were remarkably associated with a higher risk of intensive care unit admission than non-transplant patients (OR = 1.57, 95%CI: 1.07 to 2.31, P = 0.02). On the other hand, there were no statistically significant differences between SOT recipients and non-SOT recipients in mechanical ventilation need (OR = 1.55, 95%CI: 0.98 to 2.44, P = 0.06). In addition, we found that SOT recipients with COVID-19 had 1.40-fold increased odds of mortality than non-SOT recipients (OR = 1.40, 95%CI: 1.10 to 1.79, P = 0.007). Moreover, pooled analysis of adjusted results revealed that SOT recipients had a greater risk of mortality compared with non-SOT patients (HR = 1.54, 95%CI: 1.03 to 2.32, P = 0.037). LIMITATIONS: The main limitations in our study are attributed to the relatively small sample size, short follow-up period, and the fact that most of the studies included were retrospective in design. CONCLUSIONS: The results of this study indicate that SOT recipients with COVID-19 had a more significant risk of COVID-19 severity and mortality than the general population.
