Abstract Adverse clinical outcomes related to SARS‐CoV‐2 infection among liver transplant (LTx) recipients remain undefined. We performed a meta‐analysis to determine the pooled prevalence of outcomes among hospitalized LTx recipients with COVID‐19. A database search of literature published between December 1, 2019, and November 20, 2020, was performed per PRISMA guidelines. Twelve studies comprising 517 hospitalized LTx recipients with COVID‐19 were analyzed. Common presenting symptoms were fever (71%), cough (62%), dyspnea (48%), and diarrhea (28%). Approximately 77% (95% CI, 61%‐93%) of LTx recipients had a history of liver cirrhosis. The most prevalent comorbidities were hypertension (55%), diabetes (45%), and cardiac disease (21%). In‐hospital mortality was 20% (95% CI, 13%‐28%) and rose to 41% (95% CI, 19%‐63%) ( P < 0.00) with ICU admission. Additional subgroup analysis demonstrated a higher mortality risk in the elderly (>60‐65 years) (OR 4.26; 95% CI, 2.14‐8.49). There was no correlation in respect to sex or time since transplant. In summary, LTx recipients with COVID‐19 had a high prevalence of dyspnea and gastrointestinal symptoms. In‐hospital mortality was comparable to non‐transplant populations with similar comorbidities but appeared to be less than what is reported elsewhere for cirrhotic patients (26%‐40%). Importantly, the observed high case fatality in the elderly could be due to age‐associated comorbidities.
