Emerging Microbiology Diagnostics for Transplant Infections: On the Cusp of a Paradigm Shift

Azar MM, Gaston DC, Kotton CN, et al.
Transplantation: : July 2020 - Volume 104 - Issue 7 - p 1358-1384

Infection is seemingly permanently interconnected with transplantation, obvious through the impact of immunosuppression on host response to infection, but also through the underlying susceptibility of the chronic disease cohort we care for and potentially in the future to ensure tolerance to an organ does not translate into tolerance of a virus. Keeping up to date with the technologies used in the microbiology laboratory is thus crucial for all transplant clinicians. In this paper we get a transplant eye view of what is already here and what is coming soon to provide speed and accuracy unachievable by simply trying to grow organisms in the lab. multiplexed molecular panels directly applicable to blood and blood culture specimens, next-generation metagenomics, and gas chromatography mass spectrometry are changing the face of infectious disease diagnostics. This is a great article to allow you keep up to speed in this area.

TRANSPLANTATION : Just Released - August Issue

Children: how to optimize transplant centers for small children, how to allocate them livers and kidneys, and risk factors for survival after living donor livers. This issue provides a lot about the challenges of transplantation in little people. Other features this month include primate studies on tolerance with discordant results, a lesson from history on Freemartin cattle, much on various aspects of clinical liver transplantation such as how to get the best from liver kidney transplants, more on histology of rejection and antibodies in both liver and kidney transplants, and what to do about steatotic livers. Bookending our clinical practice we examine donation after uncontrolled circulatory death and the lack of impact of eHealth systems on outcomes after transplantation, a reminder that our rush to remote eHealth during the COVID-19 pandemic needs testing and may have some downsides.

Updated Guidance on Coronavirus Disease 2019 (COVID-19) for Transplant Clinicians

Updated July 14 - This is the fifth update of Coronavirus Disease 2019 (COVID-19) Guidance from the TID Section of TTS. It is important to note that information about this disease and our understanding of this virus and its impact on transplantation is evolving rapidly so the guidance may change over time. We plan to regularly update the guidance as new information becomes available. Additionally, we have added some focused reviews on key topics that we hope the community finds as an easier way to access data. These sections will be updated regularly while this master document will not be updated extensively after this update.

Focused updates include:

  • UPDATE ON EPIDEMIOLOGY OF COVID-19 IN TRANSPLANT PATIENTS
  • UPDATE ON SOT RECIPIENT ADVICE TO PREVENT COVID-19
  • DIAGNOSTIC TESTING – PCR AND SEROLOGY
  • UPDATE ON SARS-COV-2 AND ORGAN DONATION
  • UPDATE ON THERAPEUTIC AGENTS FOR COVID-19
  • TID EVIDENCE REVIEW FOR INPATIENT TREATMENT OPTIONS FOR COVID-19
  • PREVENTION AND MANAGEMENT OF COVID-19 IN HSCT RECIPIENTS

Editors and contributors to Transplantation have shared their thoughts on how they are dealing with the current crisis. While we understand that the information of today may be quite different tomorrow in this fast-moving pandemic, this report will open our forum of an international exchange on COVID for the transplant community.

Dexamethasone in Hospitalized Patients with Covid-19 — Preliminary Report
The RECOVERY Collaborative Group*

NEJM July 17,2020; DOI: 10.1056/NEJMoa2021436

This is a controlled, open-label trial comparing COVID patients to receive oral or intravenous dexamethasone (at a dose of 6 mg once daily) for up to 10 days or to receive usual care alone. A total of 2104 patients were assigned to receive dexamethasone and 4321 to receive usual care. Overall, 482 patients (22.9%) in the dexamethasone group and 1110 patients (25.7%) in the usual care group died within 28 days after randomization(age-adjusted rate ratio, 0.83; 95% confidence interval [CI], 0.75 to 0.93; P<0.001). In the dexamethasone group, the incidence of death was lower than that in the usual care group among patients receiving invasive mechanical ventilation (29.3% vs. 41.4%; rate ratio, 0.64; 95% CI, 0.51 to 0.81) and among those receiving oxygen without invasive mechanical ventilation(23.3% vs. 26.2%; rate ratio, 0.82; 95% CI, 0.72 to 0.94) but not among those who were receiving no respiratory support at randomization (17.8% vs. 14.0%; rate ratio,1.19; 95% CI, 0.91 to 1.55).


An mRNA Vaccine against SARS-CoV-2 — Preliminary Report

Buchanan, R. Pikaart‑Tautges, J.E. Ledgerwood, B.S. Graham, and J.H. Beigel, for the mRNA-1273 Study Group*

NEJM July 14, 2020, DOI: 10.1056/NEJMoa2022483

This is a phase 1, dose-escalation, open-label trial including 45 healthy adults, 18 to 55 years of age, who received two vaccinations, 28 days apart, with mRNA-1273 in a dose of 25 μg, 100 μg, or 250 μg. There were 15 participants in each dose group. The mRNA-1273 vaccine induced anti–SARS-CoV-2 immune responses in all participants, and no trial-limiting safety concerns were identified. These findings support further development of this vaccine.


Potent neutralizing antibodies directed to multiple epitopes on SARS-CoV-2 spike

Nature, July 22, 2020; https://doi.org/10.1038/s41586-020-2571-7

This article reports the isolation of 61 SARS-CoV-2-neutralizing monoclonal antibodies from 5 infected patients hospitalized with severe disease.Among these are 19 antibodies that potently neutralized the authentic SARS-CoV-2 in vitro, 9 of which exhibited exquisite potency, with 50% virus-inhibitory concentrations of 0.7 to 9 ng/mL. Epitope mapping showed this collection of 19 antibodies to be about equally divided between those directed to the receptor-binding domain (RBD) and those to the N-terminal domain (NTD), indicating that both of these regions at the top of the viral spike are immunogenic. Several of those monoclonal antibodies are promising candidates for clinical development as potential therapeutic and/or prophylactic agents against SARS-CoV-2.


Impaired type I interferon activity and inflammatory responses in severe COVID-19 patients

 J. Hadjadj et al., Science 10.1126/science.abc6027 (2020).

This article performed an integrated immune analysis on a cohort of 50 COVID-19 patients with various disease severity. A unique phenotype was observed in severe and critical patients, consisting of a highly impaired interferon (IFN) type I response (characterized by no IFN-β and low IFN-α production and activity), associated with a persistent blood viral load and an exacerbated inflammatory response. Inflammation was partially driven by the transcriptional factor NF-κB and characterized by increased tumor necrosis factor (TNF)-α and interleukin (IL)-6 production and signaling. These data suggest that type-I IFN deficiency in the blood could be a hallmark of severe COVID-19 and provide a rationale for combined therapeutic approaches.
