TTS 2020 Virtual Congress - Extended Registration Deadline

TTS 2020 VIRTUAL CONGRESS

CALL FOR VIRTUAL NETWORKING LOUNGE IDEAS

Call for Virtual Networking Lounge Ideas.

Your contributions to the Congress are paramount for the success of the meeting and advancement of the field.

Half the reason people attend congresses is to network.
Unfortunately, at a virtual event it’s hard for this to just happen naturally so we are offering these virtual networking rooms to integrate community-building moments.
Submission Deadline - August 14, 2020

Sessions will range from 45 to 90 minutes in length with multiple time zones to choose from. All sessions will be hosted on the Zoom platform managed by the technology team at TTS. The maximum capacity for each session is 300, however we recommend keeping groups much smaller (10 to 50 participants) to ensure interactivity. Our scientific program committee will work with respondents (when needed) to refine their proposals as well as assist in finding experts (when necessary).

TRANSPLANTATION - HIGHLIGHTED ARTICLE

Late Graft Loss After Kidney Transplantation: Is “Death With Function” Really Death With a Functioning Allograft?

Gaston RS, Fieberg A, Helgeson ES, et al.
Transplantation: July 2020 - Volume 104 - Issue 7 - p 1483-1490

Take 3587 patients and follow them for 5.2 years and find out what happens. This is the DeKAF study from 7 major transplant programs in the USA. The question asked and largely answered in this paper is whether the people who die with graft function are actually dying because of poor graft function or because of concomitant disease. About half of the graft losses in the study were from each of death with a functioning graft (295 patients) and death censored graft failure (350 patients). The key finding is the renal function in those who survived with maintained graft function and those who died with a functioning graft were on similar trajectories. While the study has missing data, it is clear that the group in which the patient survived but the graft was lost, were characterised by being younger and non adherent and suffering rejection. The group who died with functioning grafts were older, diabetic and had been on dialysis for longer. While some of this may seem obvious, the impact on how you follow and look after patients in this COVID impacted world is highly relevant.

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.

Seroprevalence of Antibodies to SARS-CoV-2 in 10 Sites in the United States, March 23-May 12, 2020

Published online July 21, 2020

Serum samples were tested from 16 025 persons in 10 sites in the USA; 1205 (7.5%) were 18 years or younger and 5845 (36.2%) were 65 years or older.Most specimens from each site had no evidence of antibodies to SARS-CoV-2. Adjusted estimates of the proportion of persons seroreactive to the SARS-CoV-2 spike protein antibodies ranged from 1.0% in the San Francisco Bay area (collected April 23-27) to 6.9% of persons in New York City (collected March 23-April 1). The estimated number of infections ranged from 6 to 24 times the number of reported cases; for 7 sites (Connecticut, Florida, Louisiana, Missouri, New York City metro area, Utah, and western Washington State), an estimated greater than 10 times more SARS-CoV-2 infections occurred than the number of reported cases. The findings may reflect the number of persons who had mild or no illness or who did not seek medical care or undergo testing but who still may have contributed to ongoing virus transmission in the population.

Published online July 24, 2020.

This article reports a case series of pairs of brothers without medical history and admitted to the intensive care unit (ICU) due to severe COVID-19. The 4 male patients had a mean age of 26 years (range, 21-32), with no history of major chronic disease. They were previously well before developing respiratory insufficiency due to severe COVID-19, requiring mechanical ventilation in the ICU. The mean duration of ventilatory support was 10 days (range, 9-11); the mean duration of ICU stay was 13 days (range, 10-16). One patient died. Rapid clinical whole-exome sequencing of the patients and segregation in available family members identified loss-of-function variants of the X-chromosomal TLR7. In members of family 1, a maternally inherited 4-nucleotide deletion was identified. In primary peripheral blood mononuclear cells from the patients, downstream type I interferon (IFN) signaling was transcriptionally downregulated, as measured by significantly decreased mRNA expression of IRF7, IFNB1, and ISG15 on stimulation with the TLR7 agonist imiquimod as compared with family members and controls. The production of IFN-γ, a type II IFN, was decreased in patients in response to stimulation with imiquimod.

J Am Soc Nephrol, 2020 Jul 30; doi: 10.1681/ASN.2020060827. PMID: 32732391

This article investigated the seroprevalence of SARS-CoV-2 antibodies in a hemodialysis population. Of 356 patients, 121 had been symptomatic when screened before a dialysis session and received an RT-PCR test; 79 (22.2% of the total study population) tested positive for COVID-19. Serologic testing of all 356 patients found 129 (36.2%) who tested positive for SARS-CoV-2 antibodies. Only two patients with PCR-confirmed infection did not seroconvert. Of the 129 patients with SARS-CoV-2 antibodies, 52 (40.3%) had asymptomatic disease or undetected disease by PCR testing alone.

This article investigated SARS-CoV-2 spike glycoprotein (S)-reactive CD4+ T cells in peripheral blood of patients with COVID-19 and SARS-CoV-2-unexposed healthy donors. The authors detected SARS-CoV-2 S-reactive CD4+ T cells in 83% of patients with COVID-19 but also in 35% of controls. S-reactive CD4+ T cells in HD reacted primarily to C-terminal S epitopes, which show a higher homology to spike glycoproteins of human endemic coronaviruses, compared to N-terminal epitopes. The role of pre-existing SARS-CoV-2 cross-reactive T cells for clinical outcomes remains to be determined in larger cohorts.

NIH DEEMS KIDNEY TRANSPLANTATION SAFE BETWEEN HIV-POSITIVE DONORS AND RECIPIENTS

July 29 - HIV-positive individuals with end-stage kidney disease may now have a larger pool of kidneys available to them, with recent study results from the National Institutes of Health (NIH) showing that kidneys from HIV-positive deceased donors can be used in addition to those from HIV-negative donors.

RISK OF NEW-ONSET DIABETES AFTER KIDNEY TRANSPLANTATION AND PROPORTION OF VEILLONELLA

July 30 - Patients undergoing kidney transplantation are at risk for new-onset diabetes after transplantation (NODAT). NODAT is a common complication after kidney transplantation; however, according to researchers in the Republic of Korea, the mechanism of NODAT is not fully understood. Results of recent studies suggest that in the general population gut bacteria play a key role in diabetes.

OBESITY AND OUTCOMES OF SIMULTANEOUS KIDNEY-PANCREAS TRANSPLANTATION

July 31 - In patients with type 1 diabetes as well as, more recently, type 2 diabetes, pancreas transplantation has proven effective in normalizing glucose control with equivalent patient and graft survival rates. However, according to researchers at Temple University School of Medicine, Philadelphia, Pennsylvania, there are few data available on outcomes of simultaneous kidney-pancreas transplantation in overweight and obese recipients.
