Safety of Kidney Transplantation from Donors with HIV.

BACKGROUND: Kidney transplantation from donors with human immunodeficiency virus (HIV) to recipients with HIV is an emerging practice. It has been performed since 2016 under the U.S. congressional HIV Organ Policy Equity Act and is currently approved for research only. The Department of Health and Human Services is considering expanding the procedure to clinical practice, but data are limited to small case series that did not include donors without HIV as controls. METHODS: In an observational study conducted at 26 U.S. centers, we compared transplantation of kidneys from deceased donors with HIV and donors without HIV to recipients with HIV. The primary outcome was a safety event (a composite of death from any cause, graft loss, serious adverse event, HIV breakthrough infection, persistent failure of HIV treatment, or opportunistic infection), assessed for noninferiority (margin for the upper bound of the 95% confidence interval, 3.00). Secondary outcomes included overall survival, survival without graft loss, rejection, infection, cancer, and HIV superinfection. RESULTS: We enrolled 408 transplantation candidates, of whom 198 received a kidney from a deceased donor; 99 received a kidney from a donor with HIV and 99 from a donor without HIV. The adjusted hazard ratio for the composite primary outcome was 1.00 (95% confidence interval [CI], 0.73 to 1.38), which showed noninferiority. The following secondary outcomes were similar whether the donor had HIV or not: overall survival at 1 year (94% vs. 95%) and 3 years (85% vs. 87%), survival without graft loss at 1 year (93% vs. 90%) and 3 years (84% vs. 81%), and rejection at 1 year (13% vs. 21%) and 3 years (21% vs. 24%). The incidence of serious adverse events, infections, surgical or vascular complications, and cancer was similar in the groups. The incidence of HIV breakthrough infection was higher among recipients of kidneys from donors with HIV (incidence rate ratio, 3.14; 95%, CI, 1.02 to 9.63), with one potential HIV superinfection among the 58 recipients in this group with sequence data and no persistent failures of HIV treatment. CONCLUSIONS: In this observational study of kidney transplantation in persons with HIV, transplantation from donors with HIV appeared to be noninferior to that from donors without HIV.

Drug Resistance Assessed in a Phase 3 Clinical Trial of Maribavir Therapy for Refractory or Resistant Cytomegalovirus Infection in Transplant Recipients.

BACKGROUND: This drug resistance analysis of a randomized trial includes 234 patients receiving maribavir and 116 receiving investigator-assigned standard therapy (IAT), where 56% and 24%, respectively, cleared cytomegalovirus DNA at week 8 (treatment responders). METHODS: Baseline and posttreatment plasma samples were tested for mutations conferring drug resistance in viral genes UL97, UL54, and UL27. RESULTS: At baseline, genotypic testing revealed resistance to ganciclovir, foscarnet, or cidofovir in 56% of patients receiving maribavir and 68% receiving IAT, including 9 newly phenotyped mutations. Among them, 63% (maribavir) and 21% (IAT) were treatment responders. Detected baseline maribavir resistance mutations were UL27 L193F (n = 1) and UL97 F342Y (n = 3). Posttreatment, emergent maribavir resistance mutations were detected in 60 (26%) of those randomized to maribavir, including 49 (48%) of 103 nonresponders and 25 (86%) of the 29 nonresponders where viral DNA initially cleared then rebounded while on maribavir. The most common maribavir resistance mutations were UL97 T409M (n = 34), H411Y (n = 26), and C480F (n = 21), first detected 26 to 130 (median 56) days after starting maribavir. CONCLUSIONS: Baseline maribavir resistance was rare. Drug resistance to standard cytomegalovirus antivirals did not preclude treatment response to maribavir. Rebound in plasma cytomegalovirus DNA while on maribavir strongly suggests emerging drug resistance. CLINICAL TRIALS REGISTRATION: NCT02931539.

HIV-Positive Liver Transplant Does not Alter the Latent Viral Reservoir in Recipients With Antiretroviral Therapy-Suppressed HIV.

The latent viral reservoir (LVR) remains a major barrier to HIV-1 curative strategies. It is unknown whether receiving a liver transplant from a donor with HIV might lead to an increase in the LVR because the liver is a large lymphoid organ. We found no differences in intact provirus, defective provirus, or the ratio of intact to defective provirus between recipients with ART-suppressed HIV who received a liver from a donor with (n = 19) or without HIV (n = 10). All measures remained stable from baseline by 1 year posttransplant. These data demonstrate that the LVR is stable after liver transplantation in people with HIV. Clinical Trials Registration. NCT02602262 and NCT03734393.

Into the unknown: The end of the coronavirus disease 2019 public health emergency in the United States and potential impacts on organ transplant recipients.

The public health emergency for coronavirus disease 2019 ended on April 11, 2023, 1 month earlier than its planned termination. The hasty cessation of emergency measures may negatively impact the care of solid organ transplant recipients and other immunosuppressed hosts. Accelerated pathways for drug and vaccine approvals, research funding, and insurance coverage for medical therapies and diagnostic testing are likely to be affected. Health care disparities that characterized the early pandemic may again be intensified. It is imperative that the transplant community promptly anticipate the impact of these changes and prepare accordingly to avoid disruptions in care for the most vulnerable patients.

When you need to dive in the deep end-Transplanting SARS-CoV-2 PCR+ recipients.

There is an ongoing need to understand whether transplantation during acute Coronavirus disease 2019 (COVID-19) can be performed safely, especially when urgent transplant is required. We collected retrospective data of all consecutive non-lung transplant recipients who had a positive SARS-CoV-2 polymerase chain reaction (PCR) on the day of planned deceased donor organ implantation. Data were collected from two large transplant centers from 01/01/2022 to 02/01/2023. Demographics, details regarding COVID-19 infection, waitlist priority, and details regarding transplantation were obtained. A descriptive analysis was performed. A total of 12 patients were identified: 7 renal, 4 liver, and 1 heart transplant recipient. All 12 patients were vaccinated for COVID-19. Ten were asymptomatic outpatients found positive on admission and transplanted immediately. Two were in-patients with mild COVID-19 symptoms and were reactivated on the waitlist following 3 days of remdesivir when no progression to severe COVID-19 occurred. Most patients (10/12) received remdesivir posttransplant. No complications attributed to COVID-19 were noted nor were any secondary family or healthcare worker infections observed. All recipients were managed with special isolation precautions befitting their potentially infectious state. Standard induction therapy was used in all recipients. After a median follow up period of 143 days (interquartile range: 96-201 days), 3 episodes of rejection were documented, 2/7 renal recipients experienced delayed graft function, and 2/4 liver recipients required renal replacement therapy. Graft and patient survival were 100%. Transplantation can safely proceed in select, minimally symptomatic, non-lung recipients with a positive SARS-CoV-2 PCR at the time of transplant.

National Landscape of Human Immunodeficiency Virus-Positive Deceased Organ Donors in the United States.

BACKGROUND: Organ transplantation from donors with human immunodeficiency virus (HIV) to recipients with HIV (HIV D+/R+) presents risks of donor-derived infections. Understanding clinical, immunologic, and virologic characteristics of HIV-positive donors is critical for safety. METHODS: We performed a prospective study of donors with HIV-positive and HIV false-positive (FP) test results within the HIV Organ Policy Equity (HOPE) Act in Action studies of HIV D+/R+ transplantation (ClinicalTrials.gov NCT02602262, NCT03500315, and NCT03734393). We compared clinical characteristics in HIV-positive versus FP donors. We measured CD4 T cells, HIV viral load (VL), drug resistance mutations (DRMs), coreceptor tropism, and serum antiretroviral therapy (ART) detection, using mass spectrometry in HIV-positive donors. RESULTS: Between March 2016 and March 2020, 92 donors (58 HIV positive, 34 FP), representing 98.9% of all US HOPE donors during this period, donated 177 organs (131 kidneys and 46 livers). Each year the number of donors increased. The prevalence of hepatitis B (16% vs 0%), syphilis (16% vs 0%), and cytomegalovirus (CMV; 91% vs 58%) was higher in HIV-positive versus FP donors; the prevalences of hepatitis C viremia were similar (2% vs 6%). Most HIV-positive donors (71%) had a known HIV diagnosis, of whom 90% were prescribed ART and 68% had a VL <400 copies/mL. The median CD4 T-cell count (interquartile range) was 194/µL (77-331/µL), and the median CD4 T-cell percentage was 27.0% (16.8%-36.1%). Major HIV DRMs were detected in 42%, including nonnucleoside reverse-transcriptase inhibitors (33%), integrase strand transfer inhibitors (4%), and multiclass (13%). Serum ART was detected in 46% and matched ART by history. CONCLUSION: The use of HIV-positive donor organs is increasing. HIV DRMs are common, yet resistance that would compromise integrase strand transfer inhibitor-based regimens is rare, which is reassuring regarding safety.

Early clinical experience with nirmatrelvir/ritonavir for the treatment of COVID-19 in solid organ transplant recipients.

Nirmatrelvir/ritonavir (NR) use has not yet been described in solid organ transplant recipients (SOTRs) with mild COVID-19. The objective was to evaluate outcomes among SOTR and describe the drug-drug interaction of NR. This is an IRB-approved, retrospective study of all adult SOTR on a calcineurin inhibitor (CNI) or mammalian target of rapamycin inhibitor who were prescribed NR between December 28, 2021 and January 6, 2022. A total of 25 adult SOTR were included (n = 21 tacrolimus, n = 4 cyclosporine, n = 3 everolimus, n = 1 sirolimus). All patients were instructed to follow the following standardized protocol during treatment with 5 days of NR: hold tacrolimus or mTOR inhibitor or reduce cyclosporine dose to 20% of baseline daily dose. Four patients (16%) were hospitalized by day 30; one for infectious diarrhea and three for symptoms related to COVID-19. No patients died within 30 days of receipt of NR. Median tacrolimus level pre- and post-NR were 7.4 ng/ml (IQR, 6.6-8.6) and 5.2 (IQR, 3.6-8.7), respectively. Four patients experienced a supratherapeutic tacrolimus concentration after restarting tacrolimus post-NR. Our results show the clinically significant interaction between NR and immunosuppressive agents can be reasonably managed with a standardized dosing protocol. Prescribers should carefully re-introduce CNI after the NR course is complete.

COVID-19 therapeutics and outcomes among solid organ transplant recipients during the Omicron BA.1 era.

Treatment outcomes associated with the use of novel COVID-19 therapeutics in solid organ transplant recipients (SOTR) are not well described in the literature. The objective of this analysis was to characterize 30-day hospitalization and other key secondary endpoints experienced by outpatient SOTR with mild-moderate COVID-19 treated with nirmatrelvir/ritonavir (NR), sotrovimab, or no SARS-CoV-2 specific treatment. This IRB-approved, retrospective study included 154 SOTR with a documented positive SARS-CoV-2 infection between December 16, 2021 and January 19, 2022 (a predominant Omicron BA.1 period in New York City). Patients who received NR (N = 28) or sotrovimab (N = 51) experienced a lower rate of 30-day hospitalization or death as compared to those who received no specific treatment (N = 75) (p = .009). A total of three deaths occurred, all among patients who initially received no specific treatment prior to hospitalization. These results suggest a role for SARS-CoV-2 specific agents in the treatment of SOTR with COVID-19, and that there does not appear to be any difference in effectiveness when comparing NR versus sotrovimab.

Prolonged severe acute respiratory syndrome coronavirus 2 persistence, attenuated immunologic response, and viral evolution in a solid organ transplant patient.

Unlike immunocompetent hosts, the duration of viral persistence after infection with severe acute respiratory syndrome coronavirus 2 can be prolonged in immunosuppressed patients. Here, we present a case of viral persistence for over 19 weeks in a patient with a history of solid organ transplant and explore the clinical, virologic, and immunologic course. Our patient still demonstrated viral persistence at 138 days with low polymerase chain reaction cycle threshold values and evidence of continuing viral sequence evolution indicative of ongoing virus replication. These findings have important implications for infection prevention and control recommendations in immunosuppressed patients. Immune response, including neutralizing antibody titers, T cell activity, and cytokine levels, peaked around days 44-72 after diagnosis. Anti-S trimer antibodies were low at all time points, and T cell response was attenuated by day 119. As immune response waned and viral load increased, increased genetic diversity emerged, suggesting a mechanism for the development of viral variants.

Letermovir for cytomegalovirus prophylaxis in high-risk heart transplant recipients.

Letermovir is a novel agent for the prevention of cytomegalovirus (CMV) infection and disease that, unlike traditional CMV DNA polymerase inhibitors, does not carry the risk of myelosuppression. The purpose of this study was to evaluate the safety, efficacy, and clinical application of letermovir for CMV prophylaxis in heart transplant (HT) recipients. Between November 1, 2019, and October 1, 2021, at a single, tertiary care hospital, 17 HT recipients were initiated on letermovir due to leukopenia while on valganciclovir. Fifteen (88%) had high-risk mismatch (CMV D+/R-). Median time on letermovir was 5 months (interquartile range, 2-8 months.) At the end of the study period, nine of 17 patients (52.9%) were still on letermovir and four of the 17 (23.5%) had successfully completed the prophylaxis window on letermovir and been switched to the pre-emptive strategy. One patient developed clinically significant CMV viremia in the setting of being unable to obtain medication due to insurance barriers but was later successfully restarted on letermovir. One patient was unable to tolerate letermovir due to symptoms of headache and myalgias. Two patients developed low-level non-clinically significant CMV viremia and were switched back to valacyclovir. All patients had tacrolimus dosages reduced at time of letermovir initiation to minimize the risk of supratherapeutic tacrolimus concentration. One patient required hospitalization due to symptomatic tacrolimus toxicity. For HT recipients who cannot tolerate valganciclovir, letermovir presents an alternative for CMV prophylaxis. Close monitoring for breakthrough CMV and calcineurin inhibitor levels is necessary. Larger studies are required to further delineate its use and help provide further evidence of its safety and efficacy.

The role of gastrointestinal pathogen polymerase chain reaction testing in liver transplant recipients hospitalized with diarrhea.

BACKGROUND: Diarrhea is a common symptom among liver transplant (LT) recipients and can result in significant morbidity. The utility of PCR-based multiplex gastrointestinal (GI) pathogen panels in this population is unknown. METHODS: We assessed incidence, predictors, and outcomes of GI PCR positivity among inpatients who underwent stool pathogen testing with the FilmArray multiplex GI PCR panel at our institution within 1 year following LT from April 2015 to December 2019. RESULTS: A total of 112 patients were identified. Of these, 14 (12.5%) had a positive PCR for any pathogen. Escherichia coli (n = 9) and Norovirus (n = 5) were the most common pathogens detected. Recipients with a positive PCR were significantly further from LT (median 74.5 vs. 15.5 days, p < .01) and tested earlier during hospitalization (median 1.0 vs. 9.0 days, p < .01). C. difficile was positive in 20.0% of patients with a positive PCR and 11.4% with a negative PCR. CMV viremia was observed in 11.6% of patients, all in the negative PCR group. Following a positive PCR, patients were more likely to have a change in antimicrobial regimen (71.4% vs. 28.6%, p = .02), a shorter length of stay (median 7.5 vs. 17.5 days, p < .01), and a trend toward lower rates of readmission and colonoscopy within 30 days. CONCLUSIONS: In hospitalized LT recipients with diarrhea, GI PCR pathogen identification was associated with the use of targeted antimicrobial therapy and a shorter length of stay. GI PCR testing should be considered early during admission and later in the post-LT period.

Febrile neutropenia after kidney transplantation.

Neutropenia is common after kidney transplant. There are few data on febrile neutropenia episodes (FNE) after kidney transplant. We studied FNE in a single-center retrospective cohort of 1682 kidney transplant recipients. Neutropenia (absolute neutrophil count [ANC] <1000) occurred in 32% and FNE in 3%. There were 56 FNE. Median time to FNE was 143 days, and median time from onset of neutropenia to onset of FNE was 5.5 days. The most common sources of infection were urine, blood, and lungs, and in 20% of FNE no source was identified. No infectious organism was identified in 46% of FNE, and opportunistic infections were uncommon. Patient survival was similar among those with and without FNE, but FNE was associated with increased death-censored graft failure (DCGF). Following FNE, acute rejection occurred in 31% and DCGF in 15%, often in the setting of persistent reduced immunosuppression. In conclusion, FNE are common after kidney transplant and are associated with inferior long-term outcomes.

Prevalence and predictors of SARS-CoV-2 antibodies among solid organ transplant recipients with confirmed infection.

It remains uncertain whether immunocompromised patients including solid organ transplant (SOT) recipients will have a robust antibody response to SARS-CoV-2 infection. We enrolled all adult SOT recipients at our center with confirmed SARS-CoV-2 infection who underwent antibody testing with a single commercially available anti-nucleocapsid antibody test at least 7 days after diagnosis in a retrospective cohort. Seventy SOT recipients were studied (56% kidney, 19% lung, 14% liver ± kidney, and 11% heart ± kidney recipients). Thirty-six (51%) had positive anti-nucleocapsid antibody testing, and 34 (49%) were negative. Recipients of a kidney allograft were less likely to have positive antibody testing compared to those who did not receive a kidney (p = .04). In the final multivariable model, the years from transplant to diagnosis (OR 1.26, p = .002) and baseline immunosuppression with more than two agents (OR 0.26, p = .03) were significantly associated with the antibody test result, controlling for kidney transplantation. In conclusion, among SOT recipients with confirmed infection, only 51% of patients had detectable anti-nucleocapsid antibodies, and transplant-related variables including the level and nature of immunosuppression were important predictors. These findings raise the concern that SOT recipients with COVID-19 may be less likely to form SARS-CoV-2 antibodies.

Kidney allograft biopsy findings after COVID-19.

COVID-19 has been associated with acute kidney injury and published reports of native kidney biopsies have reported diverse pathologies. Case series directed specifically to kidney allograft biopsy findings in the setting of COVID-19 are lacking. We evaluated 18 kidney transplant recipients who were infected with SARS-CoV-2 and underwent allograft biopsy. Patients had a median age of 55 years, six were female, and five were Black. Fifteen patients developed COVID-19 pneumonia, of which five required mechanical ventilation. Notably, five of 11 (45%) biopsies obtained within 1 month of positive SARS-CoV-2 PCR showed acute rejection (four with arteritis, three of which were not associated with reduced immunosuppression). The remaining six biopsies revealed podocytopathy (n = 2, collapsing glomerulopathy and lupus podocytopathy), acute tubular injury (n = 2), infarction (n = 1), and transplant glomerulopathy (n = 1). Biopsies performed >1 month after positive SARS-CoV-2 PCR revealed collapsing glomerulopathy (n = 1), acute tubular injury (n = 1), and nonspecific histologic findings (n = 5). No direct viral infection of the kidney allograft was detected by immunohistochemistry, in situ hybridization, or electron microscopy. On follow-up, two patients died and most patients showed persistent allograft dysfunction. In conclusion, we demonstrate diverse causes of kidney allograft dysfunction after COVID-19, the most common being acute rejection with arteritis.

Acute Liver Injury in COVID-19: Prevalence and Association with Clinical Outcomes in a Large U.S. Cohort.

BACKGROUND AND AIMS: Coronavirus disease 2019 (COVID-19) has been associated with acute liver injury (ALI) manifested by increased liver enzymes in reports worldwide. Prevalence of liver injury and associated clinical characteristics are not well defined. We aim to identify the prevalence of and risk factors for development of COVID-19-associated ALI in a large cohort in the United States. APPROACH AND RESULTS: In this retrospective cohort study, all patients who underwent SARS-CoV-2 testing at three hospitals in the NewYork-Presbyterian network were assessed. Of 3,381 patients, 2,273 tested positive and had higher initial and peak alanine aminotransferase (ALT) than those who tested negative. ALI was categorized as mild if ALT was greater than the upper limit of normal (ULN) but <2 times ULN, moderate if ALT was between 2 and 5 times the ULN, and severe if ALT was >5 times the ULN. Among patients who tested positive, 45% had mild, 21% moderate, and 6.4% severe liver injury (SLI). In multivariable analysis, severe ALI was significantly associated with elevated inflammatory markers, including ferritin (odds ratio [OR], 2.40; P < 0.001) and interleukin-6 (OR, 1.45; P = 0.009). Patients with SLI had a more severe clinical course, including higher rates of intensive care unit admission (69%), intubation (65%), renal replacement therapy (RRT; 33%), and mortality (42%). In multivariable analysis, peak ALT was significantly associated with death or discharge to hospice (OR, 1.14; P = 0.044), controlling for age, body mass index, diabetes, hypertension, intubation, and RRT. CONCLUSIONS: ALI is common in patients who test positive for SARS-CoV-2, but is most often mild. However, among the 6.4% of patients with SLI, a severe disease course should be anticipated.

HIV transmission through living donor kidney transplant: An 11-year follow-up on the recipient and donor.

HIV transmission via solid organ transplant is a rare but serious complication. Here, we describe long-term outcomes in a case of living donor-derived transmission of HIV in a kidney transplant recipient. After 11 years since transplant surgery, the donor shows no evidence of abnormal renal function, while the recipient continues to have a functioning graft. HIV is well controlled in both individuals. This single case report highlights the possibility of acceptable long-term outcomes in living kidney donors with HIV as well as in donor-derived HIV transmission to kidney transplant recipients.

Extended letermovir administration, beyond day 100, is effective for CMV prophylaxis in patients with graft versus host disease.

BACKGROUND: Cytomegalovirus (CMV) reactivation is associated with significant morbidity and mortality after an allogeneic hematopoietic cell transplant (AHCT), and graft versus host disease (GVHD) increases the risk of CMV reactivation. Letermovir is approved for CMV prophylaxis in CMV-seropositive patients, but has only been studied through day 100 post-transplantation in the registration trial. Its efficacy in preventing CMV in patients with GVHD requiring treatment beyond the day 100 milestone has not been studied. METHODS: We retrospectively analyzed all patients who underwent an AHCT at a single center over a period of 24 months, and identified a cohort of 20 patients who received extended duration of letermovir (beyond 100 days) after the diagnosis of GVHD. The primary end point was the incidence of clinically significant CMV infection, defined as onset of CMV disease or initiation of preemptive therapy with alternative antiviral agents. RESULTS: In this high-risk cohort, only one patient (5%) developed a clinically significant CMV infection, requiring preemptive therapy. No patients developed CMV organ disease. Three additional patients developed CMV viremia of ≥150 IU/mL while on letermovir and after the onset of GVHD, and none required additional treatment. Receipt of post-transplant cyclophosphamide (PTCy) and low CD4 count after the development of GVHD were associated with breakthrough CMV viremia while on extended duration letermovir. CONCLUSIONS: Extended duration letermovir was efficacious in preventing clinically significant CMV infections in patients with GVHD.

Baloxavir treatment of oseltamivir-resistant influenza A/H1pdm09 in two immunocompromised patients.

Few treatment options are available for oseltamivir-resistant influenza. It has been proposed that baloxavir can be effective in this setting due to its distinct mechanism of action but clinical experience is lacking for immunocompromised patients. We report two such cases treated with baloxavir after failure of oseltamivir and detection of oseltamivir resistance mutations. Baloxavir/zanamivir combination therapy was effective in one patient, but persistent viral shedding was noted with baloxavir monotherapy in the other patient.

Organ recovery from deceased donors with prior COVID-19: A case series.

Although guidance documents have been published regarding organ donation from individuals with a prior history of COVID-19 infection, no data exist regarding successful recovery and transplantation from deceased donors with a history of or positive testing suggesting a prior SARS-CoV-2 infection. Here, we report a case series of six deceased donors with a history of COVID-19 from whom 13 organs were recovered and transplanted through several of the nation's organ procurement organizations (OPOs). In addition, at least two potential donors were authorized for donation but with no organs were successfully allocated and did not proceed to recovery. No transmission of SARS-CoV-2 was reported from the six donors to recipients, procurement teams, or hospital personnel. Although more studies are needed, organ donation from deceased donors who have recovered from COVID-19 should be considered.

Outcomes of COVID-19 in solid organ transplant recipients: A matched cohort study.

Whether solid organ transplant (SOT) recipients are at increased risk of poor outcomes due to COVID-19 in comparison to the general population remains uncertain. In this study, we compared outcomes of SOT recipients and non-SOT patients hospitalized with COVID-19 in a propensity score matched analysis based on age, race, ethnicity, BMI, diabetes, and hypertension. After propensity matching, 117 SOT recipients and 350 non-SOT patients were evaluated. The median age of SOT recipients was 61 years, with a median time from transplant of 5.68 years. The most common transplanted organs were kidney (48%), followed by lung (21%), heart (19%), and liver (10%). Overall, SOT recipients were more likely to receive COVID-19 specific therapies and to require ICU admission. However, mortality (23.08% in SOT recipients vs. 23.14% in controls, P = .21) and highest level of supplemental oxygen (P = .32) required during hospitalization did not significantly differ between groups. In this propensity matched cohort study, SOT recipients hospitalized with COVID-19 had similar overall outcomes as non-SOT recipients, suggesting that chronic immunosuppression may not be an independent risk factor for poor outcomes in COVID-19.
