Abstract
BACKGROUND AND AIMS: With existing literature focusing on general quality of life, the magnitude and impact of depression among recipients after liver transplantation (LT) is unclear. Hence, we aim to evaluate the prevalence, risk factors, and outcomes for recipient-related depression after LT. METHODS: Medline and Embase were searched. Single-arm analysis was pooled using the generalized linear mixed model, and logistic regression was performed to analyze risk factors. Pairwise comparative meta-analysis in odds ratio was conducted for binary outcomes. RESULTS: Of 1069 abstracts, 189 articles underwent full-text review before the inclusion of 48 articles. Pooled depression rate among 5170 recipients was 24.52% (confidence interval [CI]: 19.46%-30.41%). Depression was most prevalent in Asia compared with other geographical regions. Younger age at transplantation (P = .019) and university education (P = .051) were protective against depression. However, those transplanted for alcoholic liver disease (odds ratio: 1.14, CI: 1.10-1.18, P ≤ 0.001) were more likely to be depressed. Depression resulted in increased odds of mortality (odds ratio: 1.82, CI: 1.08-3.07, P = .04), graft loss (P = .03), and graft rejection (P = .01). CONCLUSION: Depression is highly prevalent after LT and may be associated with increased mortality and poorer graft outcomes. More emphasis is needed on the screening of depression among higher risk recipients.
