Item Open Access Changing trends in mortality among solid organ transplant recipients hospitalized for COVID-19 during the course of the pandemic.(American journal of transplantation : official journal of the American Society of Transplantation and the American Society of Transplant Surgeons, 2022-01) Heldman, Madeleine R; Kates, Olivia S; Safa, Kassem; Kotton, Camille N; Georgia, Sarah J; Steinbrink, Julie M; Alexander, Barbara D; Hemmersbach-Miller, Marion; Blumberg, Emily A; Multani, Ashrit; Haydel, Brandy; La Hoz, Ricardo M; Moni, Lisset; Condor, Yesabeli; Flores, Sandra; Munoz, Carlos G; Guitierrez, Juan; Diaz, Esther I; Diaz, Daniela; Vianna, Rodrigo; Guerra, Giselle; Loebe, Matthias; Rakita, Robert M; Malinis, Maricar; Azar, Marwan M; Hemmige, Vagish; McCort, Margaret E; Chaudhry, Zohra S; Singh, Pooja P; Hughes Kramer, Kailey; Velioglu, Arzu; Yabu, Julie M; Morillis, Jose A; Mehta, Sapna A; Tanna, Sajal D; Ison, Michael G; Derenge, Ariella C; van Duin, David; Maximin, Adrienne; Gilbert, Carlene; Goldman, Jason D; Lease, Erika D; Fisher, Cynthia E; Limaye, Ajit P; UW COVID-19 SOT Study TeamMortality among patients hospitalized for COVID-19 has declined over the course of the pandemic. Mortality trends specifically in solid organ transplant recipients (SOTR) are unknown. Using data from a multicenter registry of SOTR hospitalized for COVID-19, we compared 28-day mortality between early 2020 (March 1, 2020-June 19, 2020) and late 2020 (June 20, 2020-December 31, 2020). Multivariable logistic regression was used to assess comorbidity-adjusted mortality. Time period of diagnosis was available for 1435/1616 (88.8%) SOTR and 971/1435 (67.7%) were hospitalized: 571/753 (75.8%) in early 2020 and 402/682 (58.9%) in late 2020 (p < .001). Crude 28-day mortality decreased between the early and late periods (112/571 [19.6%] vs. 55/402 [13.7%]) and remained lower in the late period even after adjusting for baseline comorbidities (aOR 0.67, 95% CI 0.46-0.98, p = .016). Between the early and late periods, the use of corticosteroids (≥6 mg dexamethasone/day) and remdesivir increased (62/571 [10.9%] vs. 243/402 [61.5%], p < .001 and 50/571 [8.8%] vs. 213/402 [52.2%], p < .001, respectively), and the use of hydroxychloroquine and IL-6/IL-6 receptor inhibitor decreased (329/571 [60.0%] vs. 4/492 [1.0%], p < .001 and 73/571 [12.8%] vs. 5/402 [1.2%], p < .001, respectively). Mortality among SOTR hospitalized for COVID-19 declined between early and late 2020, consistent with trends reported in the general population. The mechanism(s) underlying improved survival require further study.Item Open Access Delayed mortality among solid organ transplant recipients hospitalized for COVID-19.(Clinical infectious diseases : an official publication of the Infectious Diseases Society of America, 2022-02) Heldman, Madeleine R; Kates, Olivia S; Safa, Kassem; Kotton, Camille N; Multani, Ashrit; Georgia, Sarah J; Steinbrink, Julie M; Alexander, Barbara D; Blumberg, Emily A; Haydel, Brandy; Hemmige, Vagish; Hemmersbach-Miller, Marion; La Hoz, Ricardo M; Moni, Lisset; Condor, Yesabeli; Flores, Sandra; Munoz, Carlos G; Guitierrez, Juan; Diaz, Esther I; Diaz, Daniela; Vianna, Rodrigo; Guerra, Giselle; Loebe, Matthias; Yabu, Julie M; Kramer, Kailey Hughes; Tanna, Sajal D; Ison, Michael G; Rakita, Robert M; Malinis, Maricar; Azar, Marwan M; McCort, Margaret E; Singh, Pooja P; Velioglu, Arzu; Mehta, Sapna A; van Duin, David; Goldman, Jason D; Lease, Erika D; Wald, Anna; Limaye, Ajit P; Fisher, Cynthia E; UW Covid-19 SOT Study TeamIntroduction
Most studies of solid organ transplant (SOT) recipients with COVID-19 focus on outcomes within one month of illness onset. Delayed mortality in SOT recipients hospitalized for COVID-19 has not been fully examined.Methods
We used data from a multicenter registry to calculate mortality by 90 days following initial SARS-CoV-2 detection in SOT recipients hospitalized for COVID-19 and developed multivariable Cox proportional-hazards models to compare risk factors for death by days 28 and 90.Results
Vital status at day 90 was available for 936 of 1117 (84%) SOT recipients hospitalized for COVID-19: 190 of 936 (20%) died by 28 days and an additional 56 of 246 deaths (23%) occurred between days 29 and 90. Factors associated with mortality by day 90 included: age > 65 years [aHR 1.8 (1.3-2.4), p =<0.001], lung transplant (vs. non-lung transplant) [aHR 1.5 (1.0-2.3), p=0.05], heart failure [aHR 1.9 (1.2-2.9), p=0.006], chronic lung disease [aHR 2.3 (1.5-3.6), p<0.001] and body mass index ≥ 30 kg/m 2 [aHR 1.5 (1.1-2.0), p=0.02]. These associations were similar for mortality by day 28. Compared to diagnosis during early 2020 (March 1-June 19, 2020), diagnosis during late 2020 (June 20-December 31, 2020) was associated with lower mortality by day 28 [aHR 0.7 (0.5-1.0, p=0.04] but not by day 90 [aHR 0.9 (0.7-1.3), p=0.61].Conclusions
In SOT recipients hospitalized for COVID-19, >20% of deaths occurred between 28 and 90 days following SARS-CoV-2 diagnosis. Future investigations should consider extending follow-up duration to 90 days for more complete mortality assessment.Item Open Access Healthcare resource use among solid organ transplant recipients hospitalized with COVID-19.(Clinical transplantation, 2021-02) Heldman, Madeleine R; Kates, Olivia S; Haydel, Brandy M; Florman, Sander S; Rana, Meenakshi M; Chaudhry, Zohra S; Ramesh, Mayur S; Safa, Kassem; Kotton, Camille N; Blumberg, Emily A; Besharatian, Behdad D; Tanna, Sajal D; Ison, Michael G; Malinis, Maricar; Azar, Marwan M; Rakita, Robert M; Morillas, Jose A; Majeed, Aneela; Sait, Afrah S; Spaggiari, Mario; Hemmige, Vagish; Mehta, Sapna A; Neumann, Henry; Badami, Abbasali; Jeng, Amy; Goldman, Jason D; Lala, Anuradha; Hemmersbach-Miller, Marion; McCort, Margaret E; Bajrovic, Valida; Ortiz-Bautista, Carlos; Friedman-Moraco, Rachel; Sehgal, Sameep; Lease, Erika D; Limaye, Ajit P; Fisher, Cynthia EItem Open Access β-D-glucan surveillance with preemptive anidulafungin for invasive candidiasis in intensive care unit patients: a randomized pilot study.(PloS one, 2012-01) Hanson, Kimberly E; Pfeiffer, Christopher D; Lease, Erika D; Balch, Alfred H; Zaas, Aimee K; Perfect, John R; Alexander, Barbara DBackground
Invasive candidiasis (IC) is a devastating disease. While prompt antifungal therapy improves outcomes, empiric treatment based on the presence of fever has little clinical impact. Β-D-Glucan (BDG) is a fungal cell wall component detectable in the serum of patients with early invasive fungal infection (IFI). We evaluated the utility of BDG surveillance as a guide for preemptive antifungal therapy in at-risk intensive care unit (ICU) patients.Methods
Patients admitted to the ICU for ≥ 3 days and expected to require at least 2 additional days of intensive care were enrolled. Subjects were randomized in 3:1 fashion to receive twice weekly BDG surveillance with preemptive anidulafungin in response to a positive test or empiric antifungal treatment based on physician preference.Results
Sixty-four subjects were enrolled, with 1 proven and 5 probable cases of IC identified over a 2.5 year period. BDG levels were higher in subjects with proven/probable IC as compared to those without an IFI (117 pg/ml vs. 28 pg/ml; p<0.001). Optimal assay performance required 2 sequential BDG determinations of ≥ 80 pg/ml to define a positive test (sensitivity 100%, specificity 75%, positive predictive value 30%, negative predictive value 100%). In all, 21 preemptive and 5 empiric subjects received systemic antifungal therapy. Receipt of preemptive antifungal treatment had a significant effect on BDG concentrations (p< 0.001). Preemptive anidulafungin was safe and generally well tolerated with excellent outcome.Conclusions
BDG monitoring may be useful for identifying ICU patients at highest risk to develop an IFI as well as for monitoring treatment response. Preemptive strategies based on fungal biomarkers warrant further study.Trial registration
