Successful management of T-cell mediated rejection in a recent kidney transplant recipient with COVID-19 associated severe acute respiratory syndrome.

COVID-19-associated vasculitis has been reported as a defining feature of systemic disease including acute kidney injury. However, the understanding of COVID-19 kidney transplant-related injuries is still evolving. We report a case of AKI with isolated vasculitis (v2 lesion) in a new kidney transplant recipient with COVID-19 pneumonia.

Cytomegalovirus antiviral stewardship in the COVID-19 Era: Increasing complexity of prophylaxis and treatment and potential mitigation strategies.

Cytomegalovirus (CMV) infection is one of the most common and significant complications after solid organ transplant (SOT). Severe acute respiratory coronavirus 2 (SARS-CoV-2), which causes the novel betacoronavirus 2019 disease (COVID-19), has become the first global pandemic in 100 years. The world's attention has turned to address this unanticipated development; however, the viral infection that has long plagued outcomes after solid organ transplantation still requires vigilance. With physical distancing as the key intervention to reduce the healthcare burden, and the unease related to healthcare contact within the transplant population given the associated morbidity and mortality of COVID-19 in transplant recipients, providers have struggled to evaluate and streamline essential in-person healthcare contact, including laboratory visits. Owing to this, the COVID-19 pandemic has placed a significant strain on the delivery of CMV prophylaxis and treatment after solid organ transplantation. In this piece, we will describe issues our CMV antiviral stewardship service has encountered in the care of the transplant recipient with CMV during the this unprecedented time and share our expert opinion to approaches to providing optimal, evidenced based care during a pandemic associated with a seemingly unrelated viral infection.

Impacts and challenges of United States medical students during the COVID-19 pandemic.

The delivery of medical student education has changed rapidly during the coronavirus disease 2019 (COVID-19) pandemic. Students in their pre-clinical years have transitioned to online courses and examinations. Students in their clinical years are not permitted on clinical rotations, and face uncertainties in career exploration and the residency application process. Medical students in all stages of training are volunteering and helping their communities. The future presence of COVID-19 throughout the United States is unknown, and medical students are eager to return to their training. This paper outlines current challenges in medical student education and the various responses that have been adopted. We also discuss possible future directions for students through involvement in telemedicine, outpatient clinic visits, and non-respiratory inpatient care tasks as adequate personal protective equipment, COVID-19 testing, and resources become more widely available.

Use of Donor-Derived Cell-Free DNA for Assessment of Allograft Injury in Kidney Transplant Recipients During the Time of the Coronavirus Disease 2019 Pandemic.

BACKGROUND: Kidney allograft biopsy is the gold standard for diagnosis of rejection. Under the current extraordinary circumstances of the coronavirus disease 2019 (COVID-19), in which social distancing is key to limiting the spread of the virus, the model used to provide care to transplant recipients has undergone a very rapid transformation. In the spirit of medical distancing, we have been using the donor-derived cell-free DNA (dd-cfDNA) test for screening for rejection. METHODS: This article describes our experience with this approach between March 15th and May 20th, 2020. RESULTS: This test was obtained for-cause in 23 patients and for monitoring in 9 patients. Normal results aided in forgoing biopsy in 63% of the patients for whom the test was obtained in the outpatient setting. The test is neither 100% sensitive nor specific for rejection; however, when used in combination with the available clinical information, it can be used for determining whether bringing in a transplant recipient into a medical facility is necessary. CONCLUSIONS: In the event COVID-19 becomes a long-term challenge for our community, noninvasive biomarkers such as the dd-cfDNA may become more relevant than ever in enhancing our ability to care for our transplant patients while maximizing the distancing measures.

Early Report on Published Outcomes in Kidney Transplant Recipients Compared to Nontransplant Patients Infected With Coronavirus Disease 2019.

BACKGROUND: Kidney transplant recipients (KTR) present unique characteristics, including disease vintage, immunosuppression, and single functioning kidneys. We conducted preliminary analyses to assess the impact of coronavirus disease 2019 (COVID-19) on outcomes in KTR compared to nontransplant patients. METHODS: We evaluated published information in peer-reviewed journals between January 1, 2020, and April 24, 2020, with available data on acute kidney injury (AKI), renal replacement therapy (RRT), intensive care unit (ICU) stay, and death and compared clinical outcomes in KTR vs nontransplant recipients with COVID-19. RESULTS: A total of 19 published articles were identified, including a total of 88 KTR and 5342 nontransplant patients. The sample size varied between 2 and 2634. Mean age was 58.6 years vs 58.9 years in KTR vs nontransplant patients. Patient-level incidence of AKI (27.5% vs 13.3%, P < .001), RRT (15.4% vs 3.3%, P < .001), ICU stay (34.1% vs 15.1%, P < .001), and death (22.7% vs 16.2%, P = .10) was higher in KTR, representing relative risks of 2.06 (1.44, 2.96), 4.72 (2.62, 8.51), 2.25 (1.67, 3.03), and 1.41 (0.95, 2.08), respectively. CONCLUSION: Early results suggest that the KTR are at significantly higher risk of AKI, RRT, and ICU stay from SARS-CoV-19 infection compared to the general population. The risk of death may not be significantly different.

The care of kidney transplant recipients during a global pandemic: Challenges and strategies for success.

The global pandemic of severe acute respiratory coronavirus 2 (SARS-CoV-2), which causes the novel beta coronavirus 2019 disease (COVID-19), has become an unprecedented medical, economic, and psychosocial crisis. The pandemic and its management strategies have resulted in immense challenges for health systems, not only in caring for those with COVID-19 but also in the ongoing management of chronic medical conditions. Kidney transplant recipients present a unique challenge given their need for ongoing monitoring and management as well as their higher risk of COVID-19 infection. In the absence of clear guidelines, it is unclear how to best provide routine care to this unique patient population during the pandemic. Rigorous medical and psychosocial patient-centered risk stratification strategies are needed to avoid adverse outcomes in stable solid organ transplant recipients. This review will focus on the challenges faced by kidney transplant recipients and health care providers and provides strategies to address these issues.
