Covid-19 in recipients of living donor liver transplantation: a worse or an equivalent outcome?

Background: Coronavirus disease 2019 (Covid-19) pandemic is representing a massive burden to the community with the new virus. There is few data regarding Covid-19 in liver transplant patients. Concerns were raised regarding the course of the disease in transplanted patients due to immunosuppression and risk of hepatic injuries.

Aim: To describe the outcomes of Covid-19 infection in recipients of living-donor liver transplantation (LDLT).

Methods: Retrospective analysis of 41 recipients of LDLT diagnosed with Covid-19 by real-time PCR or CT chest criteria of Covid-19 between April 2020 and April 2021. This Cohort was derived from Ain Shams Center for Organ Transplantation database, Ain Shams Specialized Hospital, Cairo, Egypt, which is considered one of the largest centers of LDLT in the Middle East. Patients were classified to mild, moderate, severe and critics according to clinical classification released by the National Health Commission of China.

Results: A total of 41 patients and 2 patients with reinfection were included in this cohort with mean age 54 years with 74% male and 26% female. The body mass index ranged from 19.3 to 37. About 30% were described as a mild case, 46.5% were moderate, 14% were severe and 9% were critical cases. Two cases developed infection twice. Total of 20 patients (46.5%) were managed in home isolation setting, 17 patients (39.5%) needed admission to ward, 4 patients (9%) in intermediate care unit and 2 patients (4%) admitted to intensive care unit. About 60% of cases were on room air, only 3 patients needed invasive methods, 2 patients needed face mask and 1 case needed invasive CPAP. In total, 41 patients recovered (95%) and 2 patients (5%) died; 1 was Covid related and the other one was non-Covid related. Female gender, higher BMI and hypertension were associated with severe course of the disease.

Conclusion: In the setting of LDLT, the possibilities of catching Covid-19 infection are high due to chronic immunosuppression use. Yet, the outcome of infection in term of morbidity and the needs for hospital admission or intensive care is generally matched to general population.
