A single-center review of outcomes between COVID-19 vaccinated and unvaccinated liver transplant recipients.

BACKGROUND: With the availability of vaccines against SARS-COV-2, recommendations for vaccination of transplant candidates are widespread. At our institution, patients may receive liver transplant (LTx) regardless of vaccine status. The purpose of this study is to compare post-LTx outcomes between vaccinated (VAX) and unvaccinated (UNVAX) LTx recipients. METHODS: This is a retrospective, single-center study of LTx from January 1, 2021-March 30, 2022. The primary outcome is incidence of post-LTx COVID-19. Secondary outcomes include graft function, mortality, graft loss, and COVID-19 treatment. RESULTS: One hundred and seventy-seven LTx recipients were included, 57% [101/177] VAX and 43% [76/177] UNVAX. Baseline characteristics were similar between groups. Overall, 28 (36.8%) UNVAX and 34 (33.7%) VAX tested COVID-19 positive during the study period (p = .193) at a mean of 312.6 [255.4-369.8] days for UNVAX versus 254.6 [215.2-293.9] days for VAX (p = .084). COVID-19 treatment was administered in 15 (53.6%) of the UNVAX compared to 22 (64.7%) in the VAX (p = .374), although eight (28.6%) of UNVAX required hospital admission for treatment compared with two (5.9%) of VAX (p = .016). There were no statistically significant differences in death, and no COVID-19 related death or graft loss. There were no statistically significant differences in liver function tests at 3- and 12-months post LTx. CONCLUSION: In a series with a large percentage of UNVAX patients, LTx appears to be safe, with no difference in the rate of COVID-19 or transplant-related outcomes compared to VAX. While we encourage vaccination to prevent severe COVID, based on our results, vaccine status should not be reason to deny lifesaving transplant.

Comparison of outcomes in vaccinated versus unvaccinated COVID-19 kidney transplant recipients, a single center retrospective study-Is the taboo justified?

INTRODUCTION: We assessed differences in the post-transplant outcomes between COVID-19 vaccinated and unvaccinated Kidney transplant (KTx) recipients. METHODS: We conducted a retrospective, single-center study of 400 KTx from 2/1/2021 to 4/30/2022 with 6-21 months follow-up. Primary outcomes included differences in the incidence of post-transplant COVID-19, ICU admission for COVID-19, death, and graft failure between the two groups. Secondary outcomes were inpatient floor admission, outpatient-management, length of hospital stay during COVID-19 admission. We also reported rejection, DGF, CMV needing treatment, and BK PCR >10 000 in baseline characteristics. RESULT: 70.5% (282/400) were fully vaccinated, and 29.5% (118/400) were unvaccinated. 33% (92/282) of vaccinated and 39% (46/118) of unvaccinated patients developed COVID-19 (p-value .03). In both groups, 16% received outpatient treatments for COVID-19. 3% (12/282) of the vaccinated and 8% (11/118) unvaccinated were admitted to the general floors (p-value .06), and 1% (3/282) of the vaccinated and 3.3% (4/118) of the unvaccinated patients needed admission to the ICU (p-value .2). The length of stay was 12 days in both groups. 13/282 (4.6%) vaccinated patients and 7/118 (5.93%) unvaccinated patients died during the follow-up period (p-value = .3). COVID-19 was deemed the etiology of death in 5/13 cases in the vaccinated and 3/7 in the unvaccinated. DGF, rejection, CMV requiring treatment, and BK PCR >10 000 were comparable between groups. CONCLUSION: The incidence of COVID-19 was higher in unvaccinated than in vaccinated KTx. The two groups were not statistically different for other primary outcomes, including the need for hospital admissions (outpatient, general floor, ICU), length of hospital stay, death, and graft failure.

The incidence of fungal infections in pancreas transplant recipients in the absence of systemic antifungal prophylaxis.

BACKGROUND: There is a lack of high-level evidence identifying meaningful outcomes and the place in therapy for systemic perioperative antifungal prophylaxis (ppx) in pancreas transplant recipients. As our program does not routinely utilize systemic perioperative antifungal ppx in pancreas transplant recipients, we assessed the incidence of post-transplant infectious complications. METHODS: This was a single-center, retrospective cohort study of consecutive adult pancreas transplant recipients between 01/2016 and 04/2018 to describe the incidence of fungal infections. Patients with a history of previous simultaneous pancreas-kidney (SPK) transplant, HIV, or unexplained use of antifungal ppx after transplantation were excluded. The primary outcome was the incidence of fungal infections within 3 months after transplantation. RESULTS: After screening 60 patients, 56 met inclusion criteria. Within 3 months post-transplantation, two (3.6%) patients had a positive fungal culture requiring systemic antifungal treatment. The sources for infection in both cases were intra-abdominal fluid cultures, positive for Candida albicans. Both patients were treated with fluconazole. Allograft-related outcomes included a 6-month pancreas graft survival of 91.1% and pancreas transplant rejection incidence of 10.7%. CONCLUSION: In this single-center experience, pancreas transplant recipients not receiving systemic antifungal ppx had similar infectious and graft-related outcomes to what is reported in literature.
