• W3030353119 abstract "We present a case of asymptomatic coronavirus disease 2019 (COVID-19) diagnosed in a hemodialysis patient during deceased donor renal transplantation (DDRT) evaluation and discuss the challenges of excluding COVID-19 before transplantation. A 50-year-old woman with end-stage renal disease secondary to IgA nephropathy on hemodialysis was called up as first on the waitlist. She was screened for COVID-19 based on our previously published protocol1 with the addition of a chest computed tomography (CT) scan. Our patient and her brother, her only household contact, were asymptomatic, had no known contact with COVID-19 cases or suspects, and had not travelled overseas for 3 months. She continued her work as a hawker but wore a cloth mask for all activities outside her home, except during exercise. On admission, she was afebrile, with a respiratory rate of 18 breaths/min and her pulse oximetry reading was 96% on room air. Physical examination revealed bilateral basal lung crepitations without signs of volume overload. She had lymphopenia though her white cell count was normal. Her chest radiograph revealed bilateral mild, ill-defined patchy opacities, while CT of the chest showed bilateral nodular air space consolidation, predominantly in the posterior and peripheral lower lobes (Figure 1). Nasopharyngeal swab for severe acute respiratory syndrome coronavirus 2 later returned positive on the same day.FIGURE 1.: Chest radiograph and computer tomography images (on admission).Transplantation was held off, and the patient was immediately transferred to an isolation ward. She developed a temperature of 37.6°C the following morning and mild symptoms (eg, cough, myalgia, vomiting, and diarrhea) only from day 3 of admission (D3). She did not require supplemental oxygen, and her symptoms resolved on D10. Repeat respiratory swabs first returned negative on D20. The optimal strategy to exclude COVID-19 before DDRT is unclear. With significant unlinked community transmission and an incubation period of approximately 2 weeks, COVID-19 cannot be confidently excluded with clinical and epidemiological history. Dialysis patients may have minimal symptoms or present atypically (eg, with predominantly gastrointestinal symptoms).2 Home isolation is impossible if they require regular hemodialysis in the community. Laboratory findings such as lymphopenia are nonspecific. Real-time reverse transcriptase polymerase chain reaction for severe acute respiratory syndrome coronavirus 2 on respiratory specimens is used to confirm COVID-19, but its sensitivity may be affected by the patient’s functional status, type of respiratory specimen, and collection technique3 and has been reported to be initially negative, especially in mild or early illness.4 The sensitivity of respiratory swabs within a short time frame to exclude COVID-19 may be limited. Chest radiography may be a useful adjunct in the screening of COVID-19 but is not sensitive in mild or early disease. In a recent meta-analysis, CT was suggested to be more sensitive than real-time reverse transcriptase polymerase chain reaction3 but can be also negative in mild or early disease.5 CT findings are nonspecific (eg, pulmonary congestion may mimic viral pneumonia) which can add further complexity to patient assessment. Given the potentially devastating consequences of peritransplant COVID-19, we find it necessary to exclude COVID-19 as best as possible before DDRT, but this will likely remain challenging. A combination of clinical, molecular, and radiological investigations may help detect early COVID-19 but may not eliminate the risk of COVID-19 especially given the time sensitivity of DDRT. The risks and benefits of proceeding with transplantation during this pandemic needs to be carefully considered and also discussed with the patient." @default.
