COVID-19 in heart transplant recipients during February-August 2020: A systematic review.

ABSTRACT: The coronavirus disease 2019 (COVID-19) pandemic represents a major concern in immunosuppressed patients such as heart transplant recipients. Therefore, we performed a systematic review to summarize the clinical features, treatment, and outcomes of heart transplant recipients with COVID-19. We searched electronic databases from inception to January 11, 2021. Thirty-nine articles (22 case reports and 17 cohorts) involving 415 patients were included. The mean age was 59.9 ± 15.7 years and 77% of patients were men. In cohort studies including outpatients and inpatients, the hospitalization rate was 77%. The most common symptoms were fever (70%) and cough (67%). Inflammatory biomarkers (C-reactive protein and procalcitonin) were above the normal range. Forty-eight percent of patients presented with severe or critical COVID-19. Hydroxychloroquine (54%), azithromycin (14%), and lopinavir/ritonavir (14%) were the most commonly used drugs. Forty-nine percent of patients discontinued the baseline regimen of antimetabolites. In contrast, 59% and 73% continued the same regimen of calcineurin inhibitors and corticosteroids, respectively. Short-term mortality among cohorts limited to inpatients was 25%. Our review suggests that heart transplant recipients with COVID-19 exhibited similar demographic and clinical features to the general population. However, the prognosis was poor in these patients.

Project description:BackgroundImmunosuppression and comorbidities increase the risk of severe coronavirus disease-2019 (COVID-19) in solid organ transplant (SOT) recipients. The outcomes of COVID-19 in liver transplant (LT) recipients remain unclear. We aimed to analyse the outcomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in LT recipients.MethodsThe electronic databases were searched for articles published from 1 December 2019 to 20 May 2021 with MeSH terms COVID-19, SARS-CoV-2, and liver transplantation. Studies reporting outcomes in more than 10 LT recipients were included for analysis. LT vs non-LT patients with COVID-19 infection were compared for all-cause mortality, which was the primary outcome studied. We also evaluated the relation between the timing of COVID-19 infection post-LT (< one year vs > one year) and mortality.FindingsEighteen articles reporting 1,522 COVID-19 infected LT recipients were included for the systematic review. The mean age (standard deviation [SD]) was 60·38 (5·24) years, and 68·5% were men. The mean time (SD) to COVID-19 infection was 5·72 (1·75) years. Based on 17 studies (I2 = 7·34) among 1,481 LT recipients, the cumulative incidence of mortality was 17·4% (95% confidence interval [CI], 15·4-19·6). Mortality was comparable between LT (n = 610) and non-LT (n = 239,704) patients, based on four studies (odds ratio [OR], 0·8 [0·6-1·08]; P = 0·14). Additionally, there was no significant difference in mortality between those infected within one year vs after one year of LT (OR, 1·5 [0·63-3·56]; P = 0·35). The cumulative incidence of graft dysfunction was 2·3% (1·3-4·1). Nearly 23% (20·71-25) of the LT patients developed severe COVID-19 infection. Before infection, 71% and 49% of patients were on tacrolimus and mycophenolate mofetil, respectively. Immunosuppression was modified in 55·9% (38·1-72·2) patients after COVID-19 infection.InterpretationLT and non-LT patients with COVID-19 have a similar risk of adverse outcomes.
