SARS‐CoV‐2 infection in two patients following recent lung transplantation

Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) that causes coronavirus disease 2019 (COVID‐19) has become a global health problem with pandemic character. Lung transplant recipients may be particularly at risk due to the high degree of immunosuppression and the lung being the organ primarily affected by COVID‐19. We describe a 16‐year‐old male and a 64‐year‐old female recently lung transplanted patients with COVID‐19 during inpatient rehabilitation. Both patients were receiving triple immunosuppressive therapy and had no signs of allograft dysfunction. Both patients had close contact with a person who developed COVID‐19 and were tested positive for SARS‐CoV‐2. Subsequently, both patients underwent systematic screening and SARS‐CoV‐2 was ultimately detected. Although the 16‐year‐old boy was completely asymptomatic, the 64‐year‐old woman developed only mild COVID‐19. Immunosuppressive therapy was unchanged and no experimental treatment was initiated. No signs of graft involvement or dysfunction were noticed. In conclusion, our report of patients with asymptomatic SARS‐CoV‐2 infection and mild COVID‐19, respectively, may indicate that lung transplant recipients are not per se at risk for severe COVID‐19. Further observations and controlled trials are urgently needed to study SARS‐CoV‐2 infection in lung transplant recipients.     

First experience of SARS‐CoV‐2 infections in solid organ transplant recipients in the Swiss Transplant Cohort Study

Immunocompromised patients may be at increased risk for complications of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection. However, comprehensive data of SARS‐CoV‐2 infection in solid organ transplant (SOT) recipients are still lacking. We performed a multicenter nationwide observational study within the Swiss Transplant Cohort Study (STCS) to describe the epidemiology, clinical presentation, treatment and outcomes of the first microbiologically documented SARS‐CoV‐2 infection among SOT recipients. Overall, 21 patients were included with a median age of 56 years (10 kidney, 5 liver, 1 pancreas, 1 lung, 1 heart and 3 combined transplantations). The most common presenting symptoms were fever (76%), dry cough (57%), nausea (33%), and diarrhea (33%). Ninety‐five percent and 24% of patients required hospital and ICU admission, respectively, and 19% were intubated. After a median of 33 days of follow‐up, 16 patients were discharged, 3 were still hospitalized and 2 patients died. These data suggest that clinical manifestations of SARS‐CoV‐2 infection in middle‐aged SOT recipients appear to be similar to the general population without an apparent higher rate of complications. These results need to be confirmed in larger cohorts.     

COVID‐19 pneumonia in a kidney transplant recipient successfully treated with tocilizumab and hydroxychloroquine

Coronavirus disease 2019 (COVID‐19) pneumonia has been poorly reported in solid organ transplanted patients; prognosis is uncertain and best management unclear. We describe the case of a 61‐year‐old kidney transplant recipient with several comorbidities who was hospitalized and later received a diagnosis of COVID‐19 pneumonia; the infection was successfully managed with the use of hydroxychloroquine and a single administration of tocilizumab, after immunosuppression reduction; the patient did not require mechanical ventilation. During the rapid spread of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) pandemic, transplant clinicians should be readily informed about new cases of COVID‐19 pneumonia in solid organ transplant recipients, with focus on therapeutic strategies employed and their outcome.     

Earliest cases of coronavirus disease 2019 (COVID‐19) identified in solid organ transplant recipients in the United States

With the rapidly expanding pandemic of SARS‐CoV‐2, there is concern that solid organ transplant recipients will be particularly vulnerable to infection and may experience a more severe clinical course. We report four cases of COVID‐19 in solid organ transplant recipients including recipients of kidney, liver, lung, and heart transplants. We describe each patient's medical history including transplantation history, their clinical presentation and workup, and their course from diagnosis to either hospital discharge or to improvement in symptoms. These reports demonstrate a range of symptoms, clinical severity, and disease course in solid organ transplant recipients with COVID‐19, including two hospitalized patients and two patients managed entirely in the outpatient setting.     

COVID‐19 in solid organ transplant recipients: A single‐center case series from Spain

The clinical characteristics, management, and outcome of coronavirus disease 2019 (COVID‐19) caused by severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) after solid organ transplant (SOT) remain unknown. We report our preliminary experience with 18 SOT (kidney [44.4%], liver [33.3%], and heart [22.2%]) recipients diagnosed with COVID‐19 by March 23, 2020 at a tertiary‐care center at Madrid. Median age at diagnosis was 71.0 ± 12.8 years, and the median interval since transplantation was 9.3 years. Fever (83.3%) and radiographic abnormalities in form of unilateral or bilateral/multifocal consolidations (72.2%) were the most common presentations. Lopinavir/ritonavir (usually associated with hydroxychloroquine) was used in 50.0% of patients and had to be prematurely discontinued in 2 of them. Other antiviral regimens included hydroxychloroquine monotherapy (27.8%) and interferon‐β (16.7%). As of April 4, the case‐fatality rate was 27.8% (5/18). After a median follow‐up of 18 days from symptom onset, 30.8% (4/13) of survivors developed progressive respiratory failure, 7.7% (1/13) showed stable clinical condition or improvement, and 61.5% (8/13) had been discharged home. C‐reactive protein levels at various points were significantly higher among recipients who experienced unfavorable outcome. In conclusion, this frontline report suggests that SARS‐CoV‐2 infection has a severe course in SOT recipients.     

COVID‐19 in solid organ transplant recipients: Initial report from the US epicenter

Solid organ transplant recipients may be at a high risk for SARS‐CoV‐2 infection and poor associated outcomes. We herein report our initial experience with solid organ transplant recipients with SARS‐CoV‐2 infection at two centers during the first 3 weeks of the outbreak in New York City. Baseline characteristics, clinical presentation, antiviral and immunosuppressive management were compared between patients with mild/moderate and severe disease (defined as ICU admission, intubation or death). Ninety patients were analyzed with a median age of 57 years. Forty‐six were kidney recipients, 17 lung, 13 liver, 9 heart, and 5 dual‐organ transplants. The most common presenting symptoms were fever (70%), cough (59%), and dyspnea (43%). Twenty‐two (24%) had mild, 41 (46%) moderate, and 27 (30%) severe disease. Among the 68 hospitalized patients, 12% required non‐rebreather and 35% required intubation. 91% received hydroxychloroquine, 66% azithromycin, 3% remdesivir, 21% tocilizumab, and 24% bolus steroids. Sixteen patients died (18% overall, 24% of hospitalized, 52% of ICU) and 37 (54%) were discharged. In this initial cohort, transplant recipients with COVID‐19 appear to have more severe outcomes, although testing limitations likely led to undercounting of mild/asymptomatic cases. As this outbreak unfolds, COVID‐19 has the potential to severely impact solid organ transplant recipients.     

Utilization of deceased donors during a pandemic: argument against using SARS‐CoV‐2–positive donors

Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) has rapidly become an unprecedented pandemic that has impacted society, disrupted hospital functions, strained health care resources, and impacted the lives of transplant professionals. Despite this, organ failure and the need for transplant continues throughout the United States. Considering the perpetual scarcity of deceased donor organs, Kates et al present a viewpoint that advocates for the utilization of coronavirus disease 2019 (COVID‐19)–positive donors in selected cases. We present a review of the current literature that details the potential negative consequences of COVID‐19–positive donors. The factors we consider include (1) the risk of blood transmission of SARS‐CoV‐2, (2) involvement of donor organs, (3) lack of effective therapies, (4) exposure of health care and recovery teams, (5) disease transmission and propagation, and (6) hospital resource utilization. While we acknowledge that transplant fulfills the mission of saving lives, it is imperative to consider the consequences not only to our recipients but also to the community and to health care workers, particularly in the absence of effective preventative or curative therapies. For these reasons, we believe the evidence and risks show that COVID‐19 infection should continue to remain a contraindication for donation, as has been the initial response of donation and transplant societies.     

COVID‐19 in kidney transplant recipients

There is minimal information on coronavirus disease 2019 (COVID‐19) in immunocompromised individuals. We have studied 10 patients treated at 12 adult care hospitals. Ten kidney transplant recipients tested positive for severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) by polymerase chain reaction, and 9 were admitted. The median age was 57 (interquartile range [IQR] 47‐67), 60% were male, 40% Caucasian, and 30% Black/African American. Median time from transplant to COVID‐19 testing was 2822 days (IQR 1272‐4592). The most common symptom was fever, followed by cough, myalgia, chills, and fatigue. The most common chest X‐ray and computed tomography abnormality was multifocal patchy opacities. Three patients had no abnormal findings. Leukopenia was seen in 20% of patients, and allograft function was stable in 50% of patients. Nine patients were on tacrolimus and a mycophenolic antimetabolite, and 70% were on prednisone. Hospitalized patients had their antimetabolite agent stopped. All hospitalized patients received hydroxychloroquine and azithromycin. Three patients died (30%), and 5 (50%) developed acute kidney injury. Kidney transplant recipients infected with COVID‐19 should be monitored closely in the setting of lowered immunosuppression. Most individuals required hospitalization and presenting symptoms were similar to those of nontransplant individuals.     

Clinical course of COVID‐19 in a liver transplant recipient on hemodialysis and response to tocilizumab therapy: A case report

The novel coronavirus disease 2019 (COVID‐19) is a highly infectious and rapidly spreading disease. There are limited published data on the epidemiology and outcomes of COVID‐19 infection among organ transplant recipients. After initial flulike symptoms, progression to an inflammatory phase may occur, characterized by cytokine release rapidly leading to respiratory and multiorgan failure. We report the clinical course and management of a liver transplant recipient on hemodialysis, who presented with COVID‐19 pneumonia, and despite completing a 5‐day course of hydroxychloroquine, later developed marked inflammatory manifestations with rapid improvement after administration of off‐label, single‐dose tocilizumab. We also highlight the role of lung ultrasonography in early diagnosis of the inflammatory phase of COVID‐19. Future investigation of the effects of immunomodulators among transplant recipients with COVID‐19 infection will be important.     

Novel coronavirus (SARS‐CoV‐2) infection in a renal transplant recipient: Case report

An ongoing outbreak of pneumonia associated with the severe acute respiratory coronavirus 2 (SARS‐CoV‐2) started in Wuhan, China, with cases now confirmed in multiple countries. The clinical course of patients remains to be fully characterized, clinical presentation ranges from asymptomatic infection to acute respiratory distress syndrome and acute renal failure, and no pharmacological therapies of proven efficacy yet exist. We report a case of SARS‐CoV‐2 infection in a renal transplant recipient with excellent outcome. This case states the importance of close monitoring of the concentration of cyclosporine in patients treated with lopinavir/ritonavir; the routine treatment of corticosteroid can be continued. This is a rare report of SARS‐CoV‐2 infection in a renal transplant recipient. Further data are needed to achieve better understanding of the impact of immunosuppressive therapy on the clinical presentation, severity, and outcome of SARS‐CoV‐2 infections in solid organ transplant recipients.     

Severe COVID‐19 in a renal transplant recipient: A focus on pharmacokinetics

The current coronavirus disease 2019 (COVID‐19) pandemic requires extra attention for immunocompromised patients, including solid organ transplant recipients. We report on a case of a 35‐year‐old renal transplant recipient who suffered from a severe COVID‐19 pneumonia. The clinical course was complicated by extreme overexposure to the mammalian target of rapamycin inhibitor everolimus, following coadministration of chloroquine and lopinavir/ritonavir therapy. The case is illustrative for dilemmas that transplant professionals may face in the absence of evidence‐based COVID‐19 therapy and concurrent pressure for exploration of experimental pharmacological treatment options. However, the risk‐benefit balance of experimental or off‐label therapy may be weighed differently in organ transplant recipients than in otherwise healthy COVID‐19 patients, owing to their immunocompromised status and potential drug interactions with immunosuppressive therapy. With this case report, we aimed to achieve increased awareness and improved management of drug‐drug interactions associated with the various treatment options for COVID‐19 in renal transplant patients.     

Early COVID‐19 infection after lung transplantation

COVID‐19, the clinical syndrome caused by the novel coronavirus, SARS‐CoV‐2, continues to rapidly spread, leading to significant stressors on global healthcare infrastructure. The manifestations of COVID‐19 in solid organ transplant recipients are only beginning to be understood with cases reported to date in transplant recipients on chronic immunosuppression. Herein, we report the first case of COVID‐19 in a lung transplant recipient in the immediate posttransplant period, and we describe the epidemiologic challenges in identifying the source of infection in this unique situation.     

COVID‐19 pneumonia in lung transplant recipients: Report of 2 cases

Coronavirus disease 2019 (COVID‐19) has been declared pandemic since March 2020. In Europe, Italy was the first nation affected by this infection. We report anamnestic data, clinical features, and therapeutic management of 2 lung transplant recipients with confirmed COVID‐19 pneumonia. Both patients were in good clinical condition before the infection and were receiving immunosuppression with calcineurin inhibitors (CNI), mycophenolate mofetil, and corticosteroids. Whereas mycophenolate mofetil was withdrawn in both cases, CNI were suspended only in the second patient. The first patient always maintained excellent oxygen saturation throughout hospitalization with no need for additional oxygen therapy. He was discharged with a satisfactory pulmonary function and a complete resolution of radiological and clinical findings. However, at discharge SARS‐CoV‐2 RNA could still be detected in the nasopharyngeal swab and in the stools. The second patient required mechanical ventilation, had a progressive deterioration of his clinical conditions, and had a fatal outcome. Further insight into SARS‐CoV‐2 infection is eagerly awaited to improve the outcome of transplant recipients affected by COVID‐19 pneumonia.     

Solid organ transplantation programs facing lack of empiric evidence in the COVID‐19 pandemic: A By‐proxy Society Recommendation Consensus approach

The ongoing severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) pandemic has a drastic impact on national health care systems. Given the overwhelming demand on facility capacity, the impact on all health care sectors has to be addressed. Solid organ transplantation represents a field with a high demand on staff, intensive care units, and follow‐up facilities. The great therapeutic value of organ transplantation has to be weighed against mandatory constraints of health care capacities. In addition, the management of immunosuppressed recipients has to be reassessed during the ongoing coronavirus disease 2019 (COVID‐19) pandemic. In addressing these crucial questions, transplant physicians are facing a total lack of scientific evidence. Therefore, the aim of this study was to offer an approach of consensus‐based guidance, derived from individual information of 22 transplant societies. Key recommendations were extracted and the degree of consensus among different organizations was calculated. A high degree of consensus was found for temporarily suspending nonurgent transplant procedures and living donation programs. Systematic polymerase chain reaction‐based testing of donors and recipients was broadly recommended. Additionally, more specific aspects (eg, screening of surgical explant teams and restricted use of marginal donor organs) were included in our analysis. This study offers a novel approach to informed guidance for health care management when a priori no scientific evidence is available.     

Strategies to halt 2019 novel coronavirus (SARS‐CoV‐2) spread for organ transplantation programs at the Sichuan Academy of Medical Science and Sichuan Provincial People’s Hospital,China

During the 2019 novel coronavirus (SARS‐CoV‐2) outbreak in China (from January 24 to March 11, 2020), our center performed 16 organ transplants (10 kidney, 4 liver, and 2 lung transplants) harvested from deceased donors. Regarding the strategies to prevent infections of SARS‐CoV‐2, we implemented specific measures for the donor and recipient management, as well as prevention of hospital‐acquired infections. All 16 organ recipients had a favorable outcome without SARS‐CoV‐2 infection. Our approaches aiming to interrupt the spread of SARS‐CoV‐2 within the transplantation wards were successful, and allowed us to maintain the transplantation program for deceased liver, kidney, and lung organ recipients.     

Renal transplantation during the SARS‐CoV‐2 pandemic in the UK: Experience from a large‐volume center

There is uncertainty about the safety of kidney transplantation during the SARS‐CoV‐2 pandemic due to the risk of donor transmission, nosocomial infection and immunosuppression use. We describe organ donation and transplant practice in the UK and assess whether kidney transplantation conferred a substantial risk of harm. Data from the UK transplant registry were used to describe kidney donation and transplant activity in the UK, and a detailed analysis of short‐term, single‐center, patient results in two periods: during the pre‐pandemic era from 30th December 2019 to 8th March 2020 (“Pre‐COVID era”) and the 9th March 2020 to 19th May 2020 (“COVID era”). Donor and recipient numbers fell by more than half in the COVID compared to the pre‐COVID era in the UK, but there were more kidney transplants performed in our center (42 vs. 29 COVID vs. pre‐COVID respectively). Overall outcomes, including re‐operation, delayed graft function, primary non‐function, acute rejection, length of stay and graft survival were similar between COVID and pre‐COVID era. 6/71 patients became infected with SARS‐CoV‐2 but all were discharged without critical care requirement. Transplant outcomes have remained similar within the COVID period and no serious sequelae of SARS‐CoV‐2 infection were observed in the peri‐transplant period.     

Successful treatment of severe COVID‐19 pneumonia in a liver transplant recipient

Coronavirus disease 2019 (COVID‐19) pandemic spreads rapidly and may be an increasing challenge for transplant community. Clinical data on COVID‐19 infection in transplant population is very limited. Herein we presented the clinical course and outcome of a 50‐year‐old male post liver transplantation who contracted COVID‐19, with subsequent infection of his wife. The process of illness was representative. A therapeutic regime with temporary immunosuppression withdrawal and systemic low‐dose corticosteroid as principle was involved in the management of the patient which made him recover from severe COVID‐19 pneumonia.     

Fatal outcome in a liver transplant recipient with COVID‐19

Liver injury is common in patients with COVID‐19, but little is known about its clinical presentation and severity in the context of liver transplant. We describe a case of COVID‐19 in a patient who underwent transplant 3 years ago for hepatocellular carcinoma. The patient came to clinic with symptoms of respiratory disease; pharyngeal swabs for severe acute respiratory syndrome coronavirus 2 were positive. His disease progressed rapidly from mild to critical illness and was complicated by several nosocomial infections and multiorgan failure. Despite multiple invasive procedures and rescue therapies, he died from the disease. The management of COVID‐19 in the posttransplant setting presents complex challenges, emphasizing the importance of strict prevention strategies.     

A case of SARS‐CoV‐2 pneumonia with successful antiviral therapy in a 77‐year‐old man with a heart transplant

The SARS‐CoV‐2 infection can be seen as a single disease, but it also affects patients with relevant comorbidities who may have an increased risk of a severe course of infection. In this report, we present a 77‐year‐old patient with a heart transplant receiving relevant immunosuppressive therapy who tested positive for SARS‐CoV‐2 after several days of dyspnea, dry cough, and light general symptoms. Computed tomography confirmed interstitial pneumonia. The patient received antiviral therapy with hydroxychloroquine and showed no further deterioration of the clinical state. After 12 days of hospitalization, the patient was released; he was SARS‐CoV‐2 negative and completely asymptomatic.     

Salivary detection of SARS‐CoV‐2 (COVID‐19) and implications for oral health‐care providers

The coronavirus disease 2019 (COVID‐19) pandemic has become a major public health crisis. The diagnostic and containment efforts for the disease have presented significant challenges for the global health‐care community. In this brief report, we provide perspective on the potential use of salivary specimens for detection and serial monitoring of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), based on current literature. Oral health‐care providers are at an elevated risk of exposure to COVID‐19 due to their proximity to nasopharynx of patients, and the practice involving the use of aerosol‐generating equipment. Here, we summarize the general guidelines for oral health‐care specialists for prevention of nosocomial transmission of COVID‐19, and provide specific recommendations for clinical care management.
