Kidney transplant recipients may be at high risk of developing critical COVID-19 illness due to chronic immunosuppression and comorbidities. We identified hospitalized adult kidney transplant recipients at 12 transplant centers in the US, Italy and Spain who tested positive for COVID-19. Clinical presentation, laboratory values, immunosuppression and treatment strategies were reviewed and predictors of poor clinical outcomes were determined through multivariable analyses. Among 9,845 kidney transplant recipients across centers, 144 were hospitalized due to COVID-19 during the 9-week study period. 65% were male with a mean age of 60 (±12) years, 40% Hispanic and 25% African-American. Prevalent comorbidities included hypertension (95%), diabetes (52%), obesity (49%), heart (28%) and lung (19%) disease. Therapeutic management included antimetabolite withdrawal (68%), calcineurin inhibitor withdrawal (23%), hydroxychloroquine (71%), antibiotics (74%), tocilizumab (13%) and antivirals (14%). During a median follow-up period of 52 days (IQR: 16-66 days), acute kidney injury occurred in 52% cases, respiratory failure requiring intubation in 29%, and mortality was 32%. The 44 patients who died were older, had lower lymphocyte counts and eGFR, higher serum lactate dehydrogenase, procalcitonin and IL-6 levels. In sum, hospitalized kidney transplant recipients with COVID-19 have higher rates of acute kidney injury and mortality.

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 wa...

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 transplantation (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 transplantati...

Abstract The rate of acute kidney injury (AKI) associated with patients hospitalized with Covid-19, and associated outcomes are not well understood. This study describes the presentation, risk factors and outcomes of AKI in patients hospitalized with Covid-19. We reviewed the health records for all patients hospitalized with Covid-19 between March 1, and April 5, 2020, at 13 academic and community hospitals in metropolitan New York. Patients younger than 18 years of age, with end stage kidney di...

Abstract Cytokine storm is an excessive immune response to external stimuli. The pathogenesis of the cytokine storm is complex. The disease progresses rapidly, and the mortality is high. Certain evidence shows that, during the coronavirus disease 2019 (COVID-19) epidemic, the severe deterioration of some patients has been closely related to the cytokine storm in their bodies. This article reviews the occurrence mechanism and treatment strategies of the COVID-19 virus-induced inflammatory storm i...

Abstract 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 antivira...

Purpose of review: The approach to ongoing organ transplantation and management of COVID-19 in solid organ transplant recipients (SOTR) has evolved tremendously since the pandemic's beginning. We summarize the current literature surrounding the virology of SARS-CoV-2, epidemiology of COVID-19 in transplant recipients, review the clinical features and complications of COVID-19 in SOTR, and discuss the safety and efficacy of current therapies and candidate vaccines in this population. Recent findi...

Purpose of the Review: In response to the COVID-19 pandemic, vulnerable populations, such as transplant patients, were at greater risk than the regular population. In order to protect these populations, transplant centers enacted new guidelines. We approach this review by looking at how different transplant regions responded to COVID-19 and analyze the unifying themes that have proven invaluable in the subsequent waves. Recent Findings: We noticed that most elective surgeries including living do...

The purpose of this single center retrospective study was to investigate the relationship between HLA and ABO polymorphisms and COVID-19 susceptibility and severity in kidney transplant recipients. It included 720 recipients who had COVID-19 and 1680 controls composed by recipients in follow-up who did not contact the transplantation center for COVID-19 symptoms, up to the moment of their inclusion in the study. HLA-A, -B, and -DRB1 allele groups and ABO frequencies were compared between recipie...

Abstract null null Solid organ transplant recipients are at high risk for the development of severe forms of COVID-19. However, the role of immunosuppression in the morbidity and mortality of the immune phenotype during COVID-19 in transplant recipients remains unknown. In this retrospective study, we compared peripheral blood T and B cell functional and surface markers, as well as serum antibody development during 29 cases of mild (World Health Organization 9-point Ordinal Scale (WOS) of 3-4) a...

Kidney transplant (KT) recipients with COVID-19 are at high risk of poor outcomes because of comorbidities and long-term immunosuppressive therapy (IST). There are little data on the effect of IST reduction and early graft function after COVID-19. We conducted a retrospective study on 45 consecutive KT recipients followed at the University Hospital of Modena who tested positive for COVID-19 by RT-PCR analysis. We detailed clinical management and outcomes of these patients. null Median age of pat...

Objectives: Over the last decades, there has been a significant increase in antimicrobial prescribing and consumption associated with the development of patients' adverse events and antimicrobial resistance (AMR) to the point of becoming a global priority. This study aims at evaluating antibiotic prescribing during COVID-19 pandemic from November 2019 to December 2020. Materials and Methods: A systematic review was conducted primarily through the NCBI database, using PRISMA guidelines to identif...
Coronavirus disease 2019 (COVID-19) predisposes patients to bacterial and fungal superinfections due to the impairment of the immunological system. Among the associated opportunistic fungal infections, mucormycosis is one of the least frequent but with the highest mortality. We describe 2 cases of mucormycosis in two kidney transplant recipients while they were hospitalized for SARS-CoV-2 pneumonia, with rhinosinusal and musculoskeletal involvement, respectively.

OBJECTIVES: Although some prognostic factors for COVID-19 were consistently identified across the studies, differences were found for other factors that could be due to the characteristics of the study populations and the variables incorporated into the statistical model. We aimed to a priori identify specific patient profiles and then assess their association with the outcomes in COVID-19 patients with respiratory symptoms admitted specifically to hospital wards. METHODS: We conducted a retrosp...
