Authors:

Abstract

Background Coronavirus 2019 (COVID‐19) pandemic has resulted in more than 350,000 deaths worldwide. The number of kidney transplants has declined during the pandemic. We describe our deceased donor kidney transplantation (DDKT) experience during the pandemic. Methods A retrospective study was conducted to evaluate the safety of DDKT during the COVID‐19 pandemic. Multiple preventive measures were implemented. Adult patients that underwent DDKT from 3/1/20 to 4/30/20 were included. COVID‐19 clinical manifestations from donors and recipients, and post‐transplant outcomes (COVID‐19 infections, readmissions, allograft rejection and mortality) were obtained. The kidney transplant (KT) recipients were followed until 5/31/20. Results Seventy‐six patients received kidneys from 57 donors. Fever, dyspnea and cough were reported in 1,2 and 1 donors, respectively. Thirty‐eight (66.6%) donors were tested for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS‐CoV2) prior to donation [mainly by nasopharyngeal or bronchoalveolar lavage polymerase chain reaction (PCR)] and 36 (47.3%) KT recipients were tested at the time of DDKT by nasopharyngeal PCR; all of these were negative. Our recipients were followed for a median of 63 (range: 33‐91) days. A total of 42 (55.3%) recipients were tested post‐transplant for SARS‐CoV2 by nasopharyngeal PCR including 12 patients that became symptomatic; all tests were negative except for one that was inconclusive, but it was repeated and came back negative. Forty (52.6%) KT recipients were readmitted and 7 (9.2%) had biopsy‐proven rejection during the follow‐up. None of the KT recipients transplanted during this period died. Conclusions Our cohort demonstrated that DDKT can be safely performed during the COVID‐19 pandemic when preventive measures are implemented.

1 | INTRODUCTION
InDecember2019,severalclustersofasevereacuterespiratoryill-
ness were described in Wuhan, China.1,2 These were the first cases
ofwhatwastolaterbecometheCoronavirus2019(COVID-19)pan-
demic. Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-
CoV2), a novel beta-coronavirus, was identified as the causative
agent.1,2 While initial spread was limited to China, the first inter-
national case was confirmed in Thailand on January 13, 2020.1 By
January 30, 2020, the World Health Organization declared that the
outbreak was a public health emergency of international concern.3
AsofJune1,2020,theCOVID-19pandemichasbeenresponsi-
blefo r6 , 20 6,773c asesand372 ,752deathswo rldwide ,i n18 8c ou n-
tries and regions.4 The Unit ed States (US) has b orne the bru nt of
thepandemic,with nearly29%and28% ofall worldwidecasesand
deaths, respectively. In the state of Florida, most of the cases have
occurre d in South Flo rida. The C ounties of Miam i-Dade, Brow ard,
and Palm Beach alone have accounted for 55% of all cases and
deaths of the Sunshine State.5
Solidorgantransplant(SOT)recipientsfacesignificantriskfrom
respiratory viral infec tions as they tend to be more severe in the
immunocompromisedhost.Forexample,influenzainSOTrecipients
isassociatedwithpneumoniain14%-49%ofpatients6,7 and is com-
monly associated with subsequent viral, bacterial, and fungal pneu-
monia,withaco-infectionrateof7%-29%.8,9
Kidney tr ansplanta tion is a vital int ervention fo r patients wi th
end-stagerenaldisease(ESRD).Kidneytransplantationsignificantly
improves survival as it was demonstrated in a study that showed
thatthemortalityratewas48%-82%loweramongkidneytransplant
(KT) recipients compared withpeoplewho remained onlong-term
dialysis.10 The risk of hospitalization from infec tion is also lower in
KT recipients.11 In addition, kidney transplantation is associated
with significant improvements in patient satisfaction and quality
of life.12,13However,KTrecipientsareatahigherriskofcomplica-
tionsfromCOVID-19duetotheirdegreeofimmunosuppressionand
comorbidities.14,15Anobservationalstudyof36COVID-19-positive

Inthisreport,we describeourexperienceinconductingkidney
transplants duringthe COVID-19pandemic at asingle, largetrans-
plant center located in the State of Florida.
2 | PATIENTS AND METHODS
2.1 | Study design
This is a single-center retrospective study conducted at Jackson
Memoria l-Miami Transpla nt Institute , a 1558-licensed b ed tertia ry
care teaching hospital in Miami, Florida. The study was approved by
the Institutional Review Board of the University of Miami. The main
objective of this study was to evaluate the safety of deceased donor
kidney transplantation (DDK T) duringthe COVID-19pandemic. All
the adult patients that underwent DDKT from 3/1/20 to 4/30/20
were included in the study and were followed until 5/31/20.
2.2 | Induction immunosuppression
The standard induction regimen in our institution is methylpredniso-
lone500mgIVdailyandanti-thymocyteglobulin(ATG)1mg/KgIV
daily(threedoseseach),andbasiliximab20mgIV(onpost-operative
days0and3or4).
2.3 | COVID-19 preventive measures
Since late January 2020, when thefirstcase of COVID-19was re-
ported in the United States, our hospital has implemented several
preventive measures to prepare for the upcoming crisis.
• Screening and appropriate triage of patients under investigation
forCOVID-19.
• Scaleuplocaltestingcapacity,especiallyin-housetestingtomeet
thedemandsduetotheincreasingnumberofCOVID-19cases.
• Screeningfor potential symptoms ofCOVID-19in ever y patient
admitted for transplant.
Monitoring all SOT recipient s with a ver y low threshold to test
(andre -te stwheneve rnece ss ar y)forSA RS -CoV2withanasop ha -
ryngeal swab PCR test.
• Education of transplant candidates and recipients on the impor-
tance of maintaining social distancing, using adequate personal
protection,re ducingin-personvisitsiffeasible,u tilizingtelemedi-
cine applications for routine care visits if feasible and reducing the
numberofnon-essentiallaboratoryvisits.
• A separat e location was op ened in the tr ansplant clinic t o test
symptomatic transplant patients to avoid transmission to other
patients.
• The use of surgical mask in all the medical campus facilities was
made mandatory for all the healthcare workers and employees.
• Theentranceofnon-employeestoourhospitalwasrestric ted.
• The living kidney donor and kidney/pancreas programs were
placed on hold.
• High-risk population:patientsovertheageof75 years,patient s
between70and75years old withsignificant comorbidities, pa-
tients w ith HIV and sens itized patient s (unless crossma tch was
negative a nd no human leu kocyte antig en (HLA)- donor-specific
antibodieswerenotedonLuminex®)wereplacedonhold.
Preemptive transplantation was also placed on hold unless the
patientswere veryclosetorequiredialysis(Glomerularfiltration
rateunder15mL/min).
• At the beginning of 4/2020, additional measures were imple-
mented inourDDKT program:Alldonors musttestnegative for

2.4 | Donors' demographics, clinical
manifestations, and SARS-CoV2 testing
DonorNet® was reviewed to obtain the donors' information. We
obtained epidemiological and travel history within 1 month prior to
donation. We investigated if donors had fever, cough, and dyspnea
before hospital admission by reviewing the medical-social ques-
tionnaire obtained from donors' relatives. We assessed the donors'
Chest X-rays (CXR)toevaluate for thepresenceofopacitiesorin-
filtrates. Findings suggestive of atelectasis, pleural ef fusion, and
pulmonary edema were not included. In addition, we evaluated if
the donors were tested forSARS-CoV2. The sample sources were
documentedforthosewho were screenedforSARS-CoV2.Please
notethatdonorswerenotalwaystestedforSARS-CoV2.Testingfor

(UNOS)datashowedthesignificantimpactofCOVID-19pandemic
on kidney transplantation in the United States. The total number of
kidney transplants decreased from approximately 475-525 trans-
plants a week prior to the pandemic to a nadir of 213 transplants in
a week at the height of the pandemic, with living donor transplants
decreasing to near zero numbers.20 The mortality benefit af forded
by transplantation and the sheer volume of patients on the wait-
ing list make it imperative to avoid suspension of transplantation
programsacross the countr y whenever possible. AsofJune 2020,
there were over 101,00 0 patients on the kidney transplant waitlist.
In2019,3,923patientsdiedwhilewaitingforakidneytransplant.20
In addition, kidney transplantation could theoretically reduce risk of

... The overall impact of COVID-19 on performing kidney transplants has been evaluated in two studies in this review [23,24]. In one study where patients who were waitlisted for a kidney transplant, irrespective of the overlapping comorbidity burden shared with KTRs, fared worse than their counterparts who were organ recipients [23]. ...
... Further analysis of the data demonstrated that waitlist status, age, and male sex were independent mortality risk factors, with requiring intubation to be an indicator of a poor prognosis for the patient. Another study followed a group of KTRs postoperatively and despite being at higher risk of infection from COVID-19, none of the patients contracted COVID-19 [24]. These studies demonstrated a benefit to transplantation as KTRs were less likely to require hospitalization and ultimately fared better than the patients who were awaiting a transplantation operation. ...
... According to the literature reviewed, undergoing kidney transplantation might provide a protective effect if the recipient was infected with COVID-19 when compared to those infected who were waiting for a kidney [23,24]. This is evident from the increased rates of hospital admissions of waitlisted COVID-19-positive patients, compared to hospitalizations of COVID-19-positive KTRs [23]. ...

SARS-CoV-2, responsible for the COVID-19 pandemic, is a highly infectious virus that quickly became and continues to be a public health emergency, given the severe international implications. Immunocompromised patients, such as those undergoing kidney transplantation, are at an increased risk for severe illness from COVID-19 and require hospitalization for more aggressive treatment to ensure survival. COVID-19 has been infecting kidney transplant recipients (KTRs), affecting their treatment protocols, and threatening their survival. The objective of this scoping review was to summarize the published literature regarding the impact of COVID-19 on KTRs in the United States in terms of prevention, various treatment protocols, COVID-19 vaccination, and risk factors. The databases such as PubMed, MEDLINE/Ebsco, and Embase were used to search for peer-reviewed literature. The search was restricted to articles that were published on KTRs in the United States from January 1, 2019, to March 2022. The initial search yielded 1,023 articles after removing duplicates, leading to a final selection of 16 articles after screening with inclusion and exclusion criteria. Four domains emerged from the review: (1) impacts of COVID-19 on performing kidney transplants, (2) impacts of COVID-19 vaccinations on KTRs, (3) outcomes of treatment regiments for KTRs with COVID-19, and (4) risk factors associated with an increased mortality rate of COVID-19 in KTRs. Waitlisted patients for kidney transplants had a higher risk of mortality compared to nontransplant patients. COVID-19 vaccinations in KTRs are found to be safe, and the immune response can be improved by placing patients on a low dose of mycophenolate before vaccination. Withdrawal of immunosuppressants showed a mortality rate of 20% without increasing the rate of acute kidney injury (AKI). There is evidence to support that kidney transplantation with the accompanying immunosuppressant regimen can provide KTRs with better COVID-19 infection outcomes compared to waitlisted patients. Hospitalization, graft dysfunction, AKI, and respiratory failure were the most common risk factors that increased the risk of mortality in COVID-19-positive KTRs. Withdrawing KTRs from immunosuppressive drugs increased the mortality rate. Further studies are needed to investigate the effects of specific drugs and dosages on the severity and mortality rate of COVID-19 in KTRs.
... Since then, the number of donors and transplantations has levelled off at a slightly lower level than before the pandemic. On average, the waiting time for a kidney from a deceased donor amounts to 36.4 months [3,4]. ...
... Living kidney donors are a healthy population, eager to help their loved ones, undergoing all testing strategies, and even putting themselves in free isolation 14 days prior to donation [4,8,9]. New studies and data show that a COVID 19 infection mostly results in mild viral infection symptoms with good recovery in donors [10]. ...
... An adjustment process was carried out. Screening for COVID 19 symptoms in every patient admitted for donation and transplantation, testing with a nasopharyngeal swab PCR test 24 h prior to donation, use of FFP 2 masks in all hospital facilities, restrictive visitation to the transplant department, and social distancing for donors and recipients were priority [4,6,8,12]. In addition to these measures, which were pro-vided for hospitals in Austria in general, we isolated our recipients in single rooms. ...

Due to immunosuppressive therapy, transplant patients are more susceptible to viral and bacterial infections. A potentially deadly new virus haunted us in 2020: SARS-CoV‑2, causing coronavirus disease 19 (COVID-19). We analyzed the consequences of this previously unknown risk for our living-donor transplant program in the first year of the pandemic. After the complete lockdown in spring 2020, our transplant center in Linz resumed the living-donor kidney transplantation program from June to September 2020, between the first and second waves of COVID-19 in Austria. We compared the outcomes of these living-donor kidney transplantations with the transplant outcomes of the corresponding periods of the three previous years. From June 4 to September 9, 2020, five living-donor kidney transplantations were performed. All donors and recipients were screened for COVID 19 infection by PCR testing the day before surgery. Kidney transplant recipients remained isolated in single rooms until discharge from hospital. All recipients and donors remained SARS-CoV‑2 negative during the follow-up of 10 months and have been fully vaccinated to date. The number of living transplants in the studied period of 2020 was constant compared to the same months of 2017, 2018, and 2019. Living-donor kidney transplantation can be continued using testing for SARS-CoV‑2 and meticulous hygienic precautions in epidemiologically favorable phases of the SARS-CoV‑2 pandemic. Donors and recipients should be carefully selected and informed about risks and benefits.
... In general, there are limited data in published literature on the use of TSCT as an imaging study prior to transplant. At the University of Washington Medical Center, chest CT was used to rule out COVID-19 infections in some kidney donors [13], whereas at the Jackson Memorial-Miami Transplant Institute in Miami, Florida, kidney transplant recipients were evaluated for symptoms of COVID-19 and underwent RT-PCR tests and chest radiographs [15]. At Baylor College of Medicine in Houston, Texas, transplant candidates required a negative SARSÀCoV2 nasopharyngeal swab and normal chest CT for COVIDÀ19 before transplant surgery [16]. ...
Article
Background: Kidney transplant is the preferred treatment for most patients with end-stage renal disease. Because dialyzed patients often have significant comorbidities or multimorbidities, they should be carefully evaluated before being waitlisted for transplant. The COVID-19 pandemic presents a major challenge for surgery, including transplant surgery. Owing to a fear of COVID-19 symptoms occurring in lungs, thin-section computed tomography (TSCT) became a standard evaluation technique in potential kidney transplant recipients before surgery. Methods: The aim of the study was to evaluate the rationale and usefulness of TSCT in deceased donor kidney transplant during the COVID-19 pandemic. All adult patients who underwent deceased donor kidney transplant between May 1, 2020, and December 15, 2021, were included in the study. Potential kidney transplant recipients who were admitted to the Department of General, Vascular, and Transplant Surgery at the Medical University of Warsaw in Warsaw, Poland, were tested for COVID-19 (CovGenX rapid test); blood chemistries were performed; dialysis was performed (if needed); and, on a negative reverse transcriptase polymerase chain reaction test, HRCT was performed. Results: From May 2020 until the end of December 2021, 54 patients were transplanted; however, 7 patients were disqualified after TSCT and consulted with a pulmonary specialist. Disqualification from kidney transplant accounted for 13% of the potential kidney allograft recipients. Conclusions: Despite the possibility of overdiagnosis by TSCT, TSCT should be considered a standard evaluation technique in potential kidney transplant recipients. Potential kidney transplant recipients must be periodically reassessed given the prolonged wait time for a donor kidney and the significant number of comorbid conditions in this patient population. However, more data with longer follow-ups are needed to prove or disprove the rationale to use TSCT in transplant surgery.
... Solid-organ transplant (SOT) recipients have an increased risk of suffering from respiratory viral infections and are at higher threat for complications from COVID-19, owing to their level of immunosuppression and comorbidities [1,2]. COVID-19 has also impacted transplant activity, due to concerns of a potential risk of viral transmission from donor to recipient [3,4]. ...

Background Solid-organ transplantation (SOT) from SARS-CoV-2 positive donors could be a life-saving opportunity worth grasping. We perform a systematic review of SOT using SARS-CoV-2 positive donors. Methods The search was performed in PubMed, Cochrane COVID-19 Study Register, and Web of Science databases, including studies conducted till the 31th of December 2021 from SOT adult recipients from a donor with past or current SARS-CoV-2 infection. Outcomes were viral transmission, COVID-19 symptoms, mortality, hospital stay, and complications. PROSPERO Register Number: CRD42022303242 Findings Sixty-nine recipients received 48 kidneys, 18 livers and 3 hearts from 57 donors. Six additional transplants from positive lungs were identified. IgG + anti-SARS-CoV-2 titers were detected among 10/16 recipients; only 4% (3/69) recipients were vaccinated. Non-lung transplant recipients received organs from 10/57 (17.5%) donors with persistent COVID-19 and SARS-CoV-2 RNA was detected (median 32 Cycle threshold [Ct]) in 18/57, at procurement. Among non-lung transplant recipients, SARS-CoV-2 viral transmission was not documented. Four patients presented delayed graft dysfunction, two patients acute rejection, and two patients died of septic shock. The median (IQR) hospital stay was 18 (11-28) days in recipients from symptomatic donors. Viral transmission occurred from three lung donors to their recipients, who developed COVID-19 symptoms. One of the recipients subsequently died. Conclusion Use of non-lung (kidney, liver and heart) organs from SARS-CoV-2 positive donors seem to be a safe practice, with a low risk of transmission irrespective of the presence of symptoms at the time of procurement. Low viral replication (Ct > 30) was safe among non-lung donors, even if persistently symptomatic at procurement.
... There should be a COVID-19 accessible pathway for the inhospital care of KTx recipients. Different routes for access to medical care should be developed to care for KTx recipients with respiratory symptoms [45]. ...

Purpose of Review COVID-19 pandemics have severely affected Latin America. It has resulted in SARS-CoV-2-associated clinical adverse outcomes, but also in social and economic deterioration. Consequently, it generated a significant negative impact on organ donation and kidney transplantation (KTx) activity in our region, leading to a negative impact on these patients’ survival and quality of life. For this reason, this article aimed to describe applicable logistics, organizational and clinical strategies to mitigate the effect of the COVID-19 pandemic on kidney donation and transplantation in our region. Recent Findings Absenteeism to hemodialysis sessions in patients with end-stage renal disease has been described in up to 54% in Latin America. Not surprisingly, there was a reduction in organ donation and transplants between 21 and 59%. Also, there is a higher incidence of COVID-19 positive tests in the waiting list population than KTx recipients (9.9%). However, there was a higher mortality rate in KTx recipients than the waiting list population (32%). Additionally, 59% of living donor kidney transplant programs suspended the evaluation of new donors due to the COVID-19 pandemic. Summary Throughout this manuscript, we summarize some practical tips to resume organ donation and KTx during pandemics in Latin America, such as selecting healthy donors and recipients, universal SARS-CoV-2 screening, implementing COVID-19 accessible pathways, and telehealth as a standard, and postpone all non-urgent visits.
... [3][4][5] Assessment of the risk and the impact that COVID-19 has had on candidates waitlisted for a kidney transplant and transplant recipients has largely been restricted to single-center studies or registry studies that leveraged voluntary reporting from a relatively small set of transplant centers. [6][7][8][9][10][11][12] These individual case series have included patients with varying severity of disease and have reported a wide range of mortality, making it difficult to accurately assess the excess risk experienced during the COVID-19 pandemic by these patient cohorts or the factors associated with COVID-19 mortality. 13 Even fewer studies have reported the burden of COVID-19 ...

Background and Objectives : The COVID-19 pandemic has had a profound impact on transplantation activity in the United States and globally. Several single center reports suggest higher morbidity and mortality among candidates waitlisted for a kidney transplant as well as recipients of a kidney transplant. We aim to describe 2020 mortality patterns during the COVID-19 pandemic in the United States among kidney transplant candidates and recipients. Design, Setting, Participants, and Measurements : Using national registry data for waitlisted candidates and kidney transplant recipients collected through April 23, 2021, we report demographic and clinical factors associated with COVID-19 related mortality in 2020, other deaths in 2020 and deaths in 2019 among waitlisted candidates and transplant recipients . We quantify excess all-cause deaths among candidate and recipient populations in 2020 as well as deaths directly attributed to COVID-19 in relation to pre-pandemic mortality patterns in 2019 and 2018. Results : Among waitlisted patient deaths in 2020, 11% of deaths were attributed to COVID-19, and these candidates were more likely to be male, obese, and belong to a racial/ethnic minority group. Nearly 1 in 6 deaths (16%) among active transplant recipients in the United States in 2020 was attributed to COVID-19. Recipients who died of COVID-19 were younger, more likely to be obese, had lower educational attainment, and were more likely to belong to racial/ethnic minority groups than those who died of other causes in 2020 or 2019. We found higher overall mortality in 2020 among waitlisted candidates (24%) than among kidney transplant recipients (20%) compared to 2019. Conclusions : Our analysis demonstrates higher rates of mortality associated with COVID-19 among waitlisted candidates and kidney transplant recipients in the United States in 2020.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has distorted the health-care system at a global level. Organ donation being a life-saving procedure, it continued even in the COVID era, although at a slow pace. Irrespective of the increase in renal transplants in the later era of COVID-19, the scarcity of literature for a review article in this context resulted in the genesis of this study. A retrospective data collection was conducted over various databases in the English language. The databases were thoroughly searched with keywords COVID-19, Coronavirus, SARS-CoV-2, and renal transplant. The data from various sources including original articles comprising single- and multicenter studies were collected, analyzed, and compiled over various parameters. The data were framed as mean, median, percentage, and standard deviation. We analyzed 10 single-centered studies and 4 multicenter studies conducting renal transplantation during the COVID era. The mean age of donor and recipient in the analysis was 47.6 ± 6.01 years and 47.8 ± 6.65 years, respectively. Two transplant centers used deceased renal donors only and one centre was doing transplant only on live donors and the remaining of the centres were taking both live and deceased donors. We observed that four studies had no COVID-positive recipient in their follow-up and the maximum COVID-positivity rate was 50%. Among reviewed 14 studies, 8 studies had no mortality in recipients who were COVID positive and the maximum mortality was 54%. To reduce morbidity and mortality, strict criteria for COVID-19 workup in donor and recipient patients should be followed. The type of donor has no direct relation to the risk of acquiring COVID-19 infection. The vaccination program has been accepted worldwide to reduce the severity of COVID-19 infection even in transplant patients.

Background: Solid organ transplant (SOT) recipients are at high risk for severe disease with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Emerging variants of concern have disproportionately affected this population. Data on severity and outcomes with the Omicron variant in SOT recipients is limited. Methods: Single-center, retrospective cohort study of SOT recipients diagnosed with SARS-CoV-2 infection from December 18, 2021, to January 18, 2022, when prevalence of the Omicron variant was more than 80 - 95% in the community. Univariate and multivariate logistic regression analysis was performed to identify risk factors for hospital admission. Results: We identified 166 SOT patients; 112 (67.5%) kidney, 22 (13.3%) liver, 10 (6.0%) lung, 7 (4.2%) heart, 15 (9.0%) combined transplants. SARS-CoV-2 vaccine series was completed in 59 (35.5%) recipients. Ninety-nine (59.6%) and 13 (7.8%) recipients received casirivimab/imdevimab and sotrovimab, respectively. Fifty-three (32%) recipients required hospital admission, of which 19 (35.8%) required intensive care unit level of care. Median follow up was 50 (IQR, 25 - 59) days, with mortality reported in 6 (3.6%) patients. Risk factors identified for hospital admission were African American race (p<0.001, Odds ratio [OR] 4.00, 95% Confidence Interval [CI] 1.84 - 8.70), history of coronary artery disease (p = 0.031, OR 3.50, 95% CI 1.12 - 10.87), and maintenance immunosuppression with corticosteroids (p = 0.048, OR 2.00, 95% CI 1.01 - 4.00). Conclusion: Contrary to that in the general population, we found a higher hospital admission rate in SOT recipients with omicron variant infection. Further studies to investigate the efficacy of newer treatments are necessary, even as outcomes continue to improve. This article is protected by copyright. All rights reserved.

The coronavirus 2019 (COVID-19) pandemic has disrupted health systems worldwide, including solid organ donation and transplantation programs. Guidance on how best to screen patients who are potential organ donors to minimize the risks of COVID-19 as well as how best to manage immunosuppression and reduce the risk of COVID-19 and manage infection in solid organ transplant recipients (SOTr) is needed. Methods: Iterative literature searches were conducted, the last being January 2021, by a team of 3 information specialists. Stakeholders representing key groups undertook the systematic reviews and generation of recommendations using a rapid response approach that respected the Appraisal of Guidelines for Research and Evaluation II and Grading of Recommendations, Assessment, Development and Evaluations frameworks. Results: The systematic reviews addressed multiple questions of interest. In this guidance document, we make 4 strong recommendations, 7 weak recommendations, 3 good practice statements, and 3 statements of "no recommendation." Conclusions: SOTr and patients on the waitlist are populations of interest in the COVID-19 pandemic. Currently, there is a paucity of high-quality evidence to guide decisions around deceased donation assessments and the management of SOTr and waitlist patients. Inclusion of these populations in clinical trials of therapeutic interventions, including vaccine candidates, is essential to guide best practices.

Neutralizing monoclonal antibodies such as bamlanivimab emerged as promising agents in treating kidney transplant recipients with COVID-19. However, the impact of bamlanivimab on kidney allograft histology remain unknown. We report a case of a kidney transplant recipient who received bamlanivimab for COVID-19 with subsequent histologic findings of diffuse peritubular capillary C4d staining. A 33-year-old man with end-stage kidney disease secondary to hypertension who received an ABO compatible kidney from a living donor, presented for his four-month protocol visit. He was diagnosed with COVID-19 44 days prior to his visit and had received bamlanivimab with uneventful recovery. His four-month surveillance biopsy showed diffuse C4d staining of the peritubular capillaries without other features of ABMR. Donor specific antibodies were negative on repeat evaluations. ABMR gene expression panel was negative. His creatinine was stable at 1.3 mg/dl, without albuminuria. Given the temporal relationship between bamlanivimab and our observations of diffuse C4d staining of the peritubular capillaries, we hypothesize that bamlanivimab might bind to angiotensin converting enzyme 2, resulting in classical complement pathway and C4d deposition. We elected to closely monitor kidney function which has been stable at 6 months after the biopsy. In conclusion, diffuse C4d may present following bamlanivimab administration without any evidence of ABMR.

Background: During the coronavirus disease 2019 (COVID-19) epidemic, many countries have instituted population-wide measures for social distancing. The requirement of patients on dialysis for regular treatment in settings typically not conducive to social distancing may increase their vulnerability to COVID-19. Methods: Over a 6-week period, we recorded new COVID-19 infections and outcomes for all adult patients receiving dialysis in a large dialysis center. Rapidly introduced control measures included a two-stage routine screening process at dialysis entry (temperature and symptom check, with possible cases segregated within the unit and tested for SARS-CoV-2), isolated dialysis in a separate unit for patients with infection, and universal precautions that included masks for dialysis nursing staff. Results: Of 1530 patients (median age 66 years; 58.2% men) receiving dialysis, 300 (19.6%) developed COVID-19 infection, creating a large demand for isolated outpatient dialysis and inpatient beds. An analysis that included 1219 patients attending satellite dialysis clinics found that older age was a risk factor for infection. COVID-19 infection was substantially more likely to occur among patients on in-center dialysis compared with those dialyzing at home. We observed clustering in specific units and on specific shifts, with possible implications for aspects of service design, and high rates of nursing staff illness. A predictive epidemic model estimated a reproduction number of 2.2; cumulative cases deviated favorably from the model from the fourth week, suggesting that the implemented measures controlled transmission. Conclusions: The COVID-19 epidemic affected a large proportion of patients at this dialysis center, creating service pressures exacerbated by nursing staff illness. Details of the control strategy and characteristics of this epidemic may be useful for dialysis providers and other institutions providing patient care.

SARS‐CoV‐2, a novel coronavirus responsible for a worldwide pandemic has forced drastic changes in medical practice in an alarmingly short period of time. Caregivers must modify their strategies as well as optimize the utilization of resources to ensure public and patient safety. For organ transplantation, in particular, the loss of life‐saving organs for transplantation could lead to increased waitlist mortality. The priority is to select uninfected donors to transplant uninfected recipients while maintaining safety for healthcare systems in the backdrop of a virulent pandemic. We do not yet have a standard approach to evaluating donors and recipients with possible SARS‐CoV‐2 infection. Our current communication shares a protocol for donor and transplant recipient selection during the COVID‐19 pandemic to continue life‐saving solid organ transplantation for heart, lung, liver and kidney recipients. The initial results using this protocol are presented here and meant to encourage dialogue between providers, offering ideas to improve safety in solid organ transplantation with limited health care resources. This protocol was created utilizing the guidelines of various organizations and from the clinical experience of the authors and will continue to evolve as more is understood about SARS‐CoV‐2 and how it affects organ donors and transplant recipients.

SARS-CoV-2 caused a major outbreak of severe pneumonia (COVID-19) in humans. Viral RNA was detected in multiple organs in COVID-19 patients. However, infectious SARS-CoV-2 was only isolated from respiratory specimens. Here, infectious SARS-CoV-2 was successfully isolated from urine of a COVID-19 patient. The virus isolated could infect new susceptible cells and was recognized by its’ own patient sera. Appropriate precautions should be taken to avoid transmission from urine. © 2020, © 2020 The Author(s).

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has now spread across the globe. As part of the worldwide response, many molecular diagnostic platforms have been granted Emergency Use Authorization (EUA) by the Food and Drug Administration (FDA) to identify SARS-CoV-2 positive patients. Our objective was to evaluate three sample-to-answer molecular diagnostic platforms (Cepheid Xpert® Xpress SARS-CoV-2 [Xpert Xpress], Abbott ID NOW™ COVID-19 [ID NOW], GenMark ePlex® SARS-CoV-2 Test [ePlex]) to determine analytical sensitivity, clinical performance, and workflow for the detection of SARS-CoV-2 in nasopharyngeal swabs from 108 symptomatic patients. We found that the Xpert Xpress had the lowest limit of detection (100% detection at 100 copies/mL), followed by the ePlex (100% detection at 1,000 copies/mL), and the ID NOW (20,000 copies/mL). The Xpert Xpress also had highest positive percent agreement (PPA) when compared to our reference standard (98.3%) followed by the ePlex (91.4%) and ID now (87.7%). All three assays showed 100% negative percent agreement (NPA). In the workflow analysis, the ID NOW produced the most rapid time to result per specimen (∼17 minutes) as compared to the Xpert Xpress (∼46 minutes) and the ePlex (∼1.5 hours), but what the ID NOW gained in rapid results, it lost in analytical and clinical performance. The ePlex had the longest time to results and showed a slight improvement in PPA over the ID NOW. Information about the clinical and analytical performance of these assays, as well as workflow, will be critical in making informed and timely decisions on testing platform.

A pneumonia outbreak with unknown etiology was reported in Wuhan, Hubei province, China, in December 2019, associated with the Huanan Seafood Wholesale Market. The causative agent of the outbreak was identified by the WHO as the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), producing the disease named coronavirus disease-2019 (COVID-19). The virus is closely related (96.3%) to bat coronavirus RaTG13, based on phylogenetic analysis. Human-to-human transmission has been confirmed even from asymptomatic carriers. The virus has spread to at least 200 countries, and more than 1,700,000 confirmed cases and 111,600 deaths have been recorded, with massive global increases in the number of cases daily. Therefore, the WHO has declared COVID-19 a pandemic. The disease is characterized by fever, dry cough, and chest pain with pneumonia in severe cases. In the beginning, the world public health authorities tried to eradicate the disease in China through quarantine but are now transitioning to prevention strategies worldwide to delay its spread. To date, there are no available vaccines or specific therapeutic drugs to treat the virus. There are many knowledge gaps about the newly emerged SARS-CoV-2, leading to misinformation. Therefore, in this review, we provide recent information about the COVID-19 pandemic. This review also provides insights for the control of pathogenic infections in humans such as SARS-CoV-2 infection and future spillovers.

The outcome of SARS-CoV2 infection in patients who have received a kidney allograft and are being treated with immunosuppression is unclear. We describe 20 kidney transplant recipients (median age 59 years [inter quartile range 51-64 years], median age of transplant 13 years [9-20 years], baseline eGFR 36.5 [23-47.5]) with SARS-CoV2 induced pneumonia. At admission, all had immunosuppression withdrawn and were started on methylprednisolone 16 mg/day, all but one was commenced on antiviral therapy and hydroxychloroquine with doses adjusted for kidney function. At baseline, all patients presented fever but only one complained of difficulty in breathing. Half of patients showed chest radiographic evidence of bilateral infiltrates while the other half showed unilateral changes or no infiltrates. During a median follow-up of seven days, 87% experienced a radiological progression and among those 73% required escalation of oxygen therapy. Six patients developed acute kidney injury with one requiring hemodialysis. Six of 12 patients were treated with tocilizumab, a humanized monoclonal antibody to the IL-6 receptor. Overall, five kidney transplant recipients died after a median period of 15 days [15-19] from symptom onset. These preliminary findings describe a rapid clinical deterioration associated with chest radiographic deterioration and escalating oxygen requirement in renal transplant recipients with SARS-Cov2 pneumonia. Thus, in this limited cohort of long-term kidney transplant patients, SARS-CoV-2 induced pneumonia is characterized by high risk of progression and significant mortality.

Objective The purpose of this article was to perform a systematic review and meta-analysis regarding the diagnostic test accuracy of chest CT for detecting coronavirus disease 2019 (COVID-19).Methods PubMed, Embase, Web of Science, and CNKI were searched up to March 12, 2020. We included studies providing information regarding diagnostic test accuracy of chest CT for COVID-19 detection. The methodological quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 tool. Sensitivity and specificity were pooled.ResultsSixteen studies (n = 3186 patients) were included. The risks of bias in all studies were moderate in general. Pooled sensitivity was 92% (95% CI = 86–96%), and two studies reported specificity (25% [95% CI = 22–30%] and 33% [95% CI = 23–44%], respectively). There was substantial heterogeneity according to Cochran’s Q test (p < 0.01) and Higgins I2 heterogeneity index (96% for sensitivity). After dividing the studies into two groups based on the study site, we found that the sensitivity of chest CT was great in Wuhan (the most affected city by the epidemic) and the sensitivity values were very close to each other (97%, 96%, and 99%, respectively). In the regions other than Wuhan, the sensitivity varied from 61 to 98%.Conclusion Chest CT offers the great sensitivity for detecting COVID-19, especially in a region with severe epidemic situation. However, the specificity is low. In the context of emergency disease control, chest CT provides a fast, convenient, and effective method to early recognize suspicious cases and might contribute to confine epidemic.Key Points• Chest CT has a high sensitivity for detecting COVID-19, especially in a region with severe epidemic, which is helpful to early recognize suspicious cases and might contribute to confine epidemic.

Background Coronavirus disease 2019 (COVID-19) was first reported in Wuhan in December 2019 and has rapidly spread across different cities within and outside China. Hong Kong started to prepare for COVID-19 on 31st December 2019 and infection control measures in public hospitals were tightened to limit nosocomial transmission within healthcare facilities. However, the recommendations on the transmission-based precautions required for COVID-19 in hospital settings vary from droplet and contact precautions, to contact and airborne precautions with placement of patients in airborne infection isolation rooms. Aim To describe an outbreak investigation of a patient with COVID-19 who was nursed in an open cubicle of a general ward before the diagnosis was made. Method Contacts were identified and risk categorized as ‘close’ or ‘casual’ for decisions on quarantine and/or medical surveillance. Respiratory specimens were collected from contacts who developed fever, and/or respiratory symptoms during the surveillance period and were tested for SARS-CoV-2. Findings A total of 71 staff and 49 patients were identified from contact tracing, seven staff and 10 patients fulfilled the criteria of ‘close contact’. At the end of 28-day surveillance, 76 tests were performed on 52 contacts and all were negative, including all patient close contacts and six of the seven staff close contacts. The remaining contacts were asymptomatic throughout the surveillance period. Conclusion Our findings suggest that SARS-CoV-2 is not spread by an airborne route, and nosocomial transmissions can be prevented through vigilant basic infection control measures, including wearing of surgical masks, hand and environmental hygiene.
