OBJECTIVE:The feasibility and 6-month outcome safety of lung transplants (LTs) from hepatitis C virus (HCV)-viremic donors for HCV-seronegative recipients (R-) were established in 2019, but longer-term safety and uptake of this practice nationally remain unknown. METHODS:testing, rank-sum testing, and Cox regression to compare posttransplant outcomes between HCV D+/R- and D-/R- LT recipients. RESULTS:HCV D+/R- LT increased from 2 to 97/year; centers performing HCV D+/R- LT increased from 1 to 25. HCV D+/R- versus HCV D-/R- LT recipients had more obstructive disease (35.7% vs 23.3%, P < .001), lower lung allocation score (36.5 vs 41.1, P < .001), and longer waitlist time (P = .002). HCV D+/R- LT had similar risk of acute rejection (adjusted odds ratio [aOR], 0.87; P = .58), extracorporeal membranous oxygenation (aOR, 1.94; P = .10), and tracheostomy (aOR, 0.42; P = .16); similar median hospital stay (P = .07); and lower risk of ventilator > 48 hours (aOR, 0.68; P = .006). Adjusting for donor, recipient, and transplant characteristics, risk of all-cause graft failure and mortality were similar at 30 days, 1 year, and 3 years for HCV D+/R- versus HCV D-/R- LT (all P > .1), as well as for high- (≥20/year) versus low-volume LT centers and high- (≥5/year) versus low-volume HCV D+/R- LT centers (all P > .5). CONCLUSIONS:HCV D+/R- and HCV D-/R- LT have similar outcomes at 3 years posttransplant. These results underscore the safety of HCV D+/R- LT and the potential benefit of expanding this practice further.

BACKGROUND:Postacute sequelae of SARS-CoV-2 infection (PASC) is an increasingly recognized phenomenon and manifested by long-lasting cognitive, mental, and physical symptoms beyond the acute infection period. We aimed to estimate the frequency of PASC symptoms in solid organ transplant (SOT) recipients and compared their frequency between those with SARS-CoV-2 infection requiring hospitalization and those who did not require hospitalization. METHODS:A survey consisting of 7 standardized questionnaires was administered to 111 SOT recipients with history of SARS-CoV-2 infection diagnosed >4 wk before survey administration. RESULTS:Median (interquartile range) time from SARS-CoV-2 diagnosis was 167 d (138-221). Hospitalization for SARS-CoV-2 infection was reported in 33 (30%) participants. Symptoms after the COVID episode were perceived as following: significant trauma (53%), cognitive decline (50%), fatigue (41%), depression (36%), breathing problems (35%), anxiety (23%), dysgeusia (22%), dysosmia (21%), and pain (19%). Hospitalized patients had poorer median scores in cognition (Quick Dementia Rating System survey score: 2.0 versus 0.5, P = 0.02), quality of life (Health-related Quality of Life survey: 2.0 versus 1.0, P = 0.015), physical health (Global physical health scale: 10.0 versus 11.0, P = 0.005), respiratory status (Breathlessness, Cough and Sputum Scale: 1.0 versus 0.0, P = 0.035), and pain (Pain score: 3 versus 0 out of 10, P = 0.003). Among patients with infection >6 mo prior, some symptoms were still present as following: abnormal breathing (42%), cough (40%), dysosmia (29%), and dysgeusia (34%). CONCLUSIONS:SOT recipients reported a high frequency of PASC symptoms. Multidisciplinary approach is needed to care for these patients beyond the acute phase.

BACKGROUND:Despite the societal benefits of live kidney donation, Black donors may be more likely than White donors to develop hypertension (HTN) and chronic kidney disease after donation. Among live kidney donors diagnosed with post-donation HTN, little is known about potential racial/ethnic differences in HTN self-care behaviors and perceived susceptibility to developing kidney disease. METHODS:We ascertained electronic medical records and phone survey data from live donors enrolled in the multi-center Wellness and Health Outcomes of LivE Donors (WHOLE-Donor) Hypertension Care Study between May 2013 and April 2020. Using multivariable logistic regression models performed January through June 2021, we examined potential associations of donor race/ethnicity with perceived susceptibility to kidney disease and self-care behaviors (ie, Behavioral Risk Factor Surveillance System measure assessing self-reported actions to control high blood pressure). RESULTS:The study included 318 US-based live kidney donors who developed post-donation HTN (57.6% female; 78.9% White; 18.6% Black; and mean age 46.7 years at donation). Black donors were equally as likely as White donors to report being moderately or strongly concerned about developing kidney disease (adjusted odds ratio, aOR: 1.27, 95%CI: .66, 2.14, P=.57). Donors with diabetes were more likely than those without diabetes (aOR: 2.43, 95%CI: 1.03, 5.01, P=.04), while donors aged >50 years were less likely than younger donors (aOR: .39, 95%CI: .18, .85, P=.02) to report being moderately or strongly concerned about kidney disease. Overall, 87% of donors reported taking at least one action to help control blood pressure, with no significant differences by sociodemographic factors. CONCLUSIONS:We found no substantial differences in perceived susceptibility to kidney disease among Black and White donors, despite published evidence that Black donors may experience greater risk of developing kidney disease than White donors. Behavioral interventions to enhance knowledge about future disease risk, attitudes, and self-care strategies among living kidney donors may be beneficial.
