The viral load in a patient's SARS-CoV-2 PCR test can be approximately quantified using the cycle threshold (Ct) value. Different reports suggest lower Ct values associated with higher viral load, viral recovery and more severe illness; therefore, this may aid in the pretransplant evaluation. 5, 6 The values that have shown to not be associated with cell culture viral recovery or range from >24 (especially after 8 days from symptom onset) to 34. 5, 7, 8 We present two patients who underwent successful deceased donor liver transplantation (DDLT) with a positive SARS-CoV-2 nasopharyngeal PCR. indirect marker of viral load, may be useful in assessing candidacy. 10, 11 The decision of the timing to pursue liver transplant in the setting of high MELD and recent COVID-19 infection remains complicated and requires careful pretransplant evaluation based on individual risk and benefit. While delaying surgery at least 7 weeks is preferred to minimize postoperative mortality and allow for conversion to negative PCR testing, this may not be feasible for patients awaiting liver transplantation who are at high risk for morality due to their underlying disease. These cases suggest that it is feasible to pursue DDLT at a shorter time interval depending on careful individual risk assessment and considering the limited resource of an organ. Nicole C.
