ABSTRACT
Purpose: Describe outcomes of patients (pt) with pre-tx COVID-19. Method(s): Multicenter study of SOT/HCT candidates who had a positive (pos) SARS-CoV-2 PCR pre-tx. Result(s): Pre-tx: Of 208 pt, median age was 56 (range 3-76). 87.8% were SOT candidates (40.5% kidney, 40.5% liver, 9.8% lung, 6.9% heart, 2.3% pancreas) and 13.9% were HCT candidates (54.2% allo, 45.8% auto). Pt underwent a median of 2 tests (range 1 - 14). In 41% of pt, > 1 neg PCR was required by the tx center before reactivation. Neg PCR was documented in 67.4% of pt at a median of 41 days (18-68) after pos PCR. Waitlist mortality was 11.0%;deaths were due to COVID-19 in 60% (12/20). Post-tx (all pt): 78 pt underwent tx at a median of 65.5 days (range 17-324) from COVID-19;71/78 have completed 4-weeks of follow-up. 24/78 (30.7%) pt were still PCR pos at time of tx (details below). 54/78 (69.2%) pt underwent routine PCR testing post-tx;62% were tested regularly for 8 weeks. Only 1 pt, who remained asymptomatic, developed recurrent pos PCR on surveillance testing 18 days post-tx. 1 pt had graft loss. There were no deaths at 4 weeks post-tx. Pt transplanted without a negative PCR: 24 pt with COVID-19 did not have neg PCR at time of tx: 9 (37.5%) kidney, 9 (37.5%) liver, 2 (8.3%) SLK, 1 (4.2%) lung, 1 heart (4.2%), 2 auto-HSCT (8.3%), 2 allo-HSCT (8.3%). Of 24 pt who were reactivated at a median of 21 days (range 8 - 38) from COVID-19 diagnosis, 7 underwent tx emergently (5 liver, 1 lung, 1 heart). 20/24 completed 4-weeks of follow-up;all were alive. PCR Cycle thresholds (Ct) increased over time, suggesting a reduction in SARS-CoV-2 viral loads with time elapsed since COVID-19 diagnosis. Conclusion(s): Short-term outcomes of transplantation in SOT/HCT candidates with prior COVID-19 were promising in this small cohort, even with a positive PCR going into transplant. Whether documentation of a negative PCR should be required for all tx candidates with a history of COVID-19 prior to transplantation should be investigated further, particularly among lung tx candidates. For certain tx candidates with COVID-19, relying time-based strategy instead of a test-based strategy may be safe.
ABSTRACT
The COVID-19 pandemic has forced many governments to impose social distancing measures upon its citizens, including in the Netherlands. Motivating adolescents to adhere to measures such as social distancing can be challenging, since adolescents are relatively more affected by them, while experiencing virtually no personal health benefit. In addition, the COVID-19 pandemic seems to impact the social environment of adolescents in schools, as some media sources have reported bullying and stigmatisation of students with an Asian appearance. This study aims to explore the experiences of adolescents regarding their Health-Protective Behaviour (HPB), as well as the prevalence and expression of stigma towards ethnic minorities within the context of the first wave of COVID-19 pandemic. We performed a cross-sectional mixed-methods study, including two independent online questionnaires. An adapted version of the "HPB" questionnaire (n = 528) and the "Measure of Disease-Related Stigma (MDRS)" questionnaire (n = 380), were administered to Dutch adolescents of 10-16 years old, attending primary or secondary school. Furthermore, 15 interviews were held with eight male and seven female adolescents. All data collection took place between March 17 and April 20, 2020. Results show that adolescents perceive COVID-19 as a threat to other peoples' health, rather than their own, and report adherence to public health measures in the interest of older and more vulnerable members of their community. We found no convincing evidence for widespread misinformation or stigmatising of certain ethnic groups among adolescents related to COVID-19 during this study. Participants acknowledged such behaviour happened in the early stages of the pandemic, before this study was initiated. Adolescents are a vital group for public health researchers to engage with during a pandemic, even when reaching them can be challenging.
