ABSTRACT

Clinical management of transplant patients abruptly changed during the first months of COVID-19 pandemic (March to May 2020). The new situation led to very significant challenges, such as new forms of relationship between healthcare providers and patients and other professionals, design of protocols to prevent disease transmission and treatment of infected patients, management of waiting lists and of transplant programs during state/city lockdown, relevant reduction of medical training and educational activities, halt or delays of ongoing research, etc. The two main objectives of the current report are: 1) to promote a project of best practices in transplantation taking advantage of the knowledge and experience acquired by professionals during the evolving situation of the COVID-19 pandemic, both in performing their usual care activity, as well as in the adjustments taken to adapt to the clinical context, and 2) to create a document that collects these best practices, thus allowing the creation of a useful compendium for the exchange of knowledge between different Transplant Units. The scientific committee and expert panel finally standardized 30 best practices, including for the pretransplant period (n = 9), peritransplant period (n = 7), postransplant period (n = 8) and training and communication (n = 6). Many aspects of hospitals and units networking, telematic approaches, patient care, value-based medicine, hospitalization, and outpatient visit strategies, training for novelties and communication skills were covered. Massive vaccination has greatly improved the outcomes of the pandemic, with a decrease in severe cases requiring intensive care and a reduction in mortality. However, suboptimal responses to vaccines have been observed in transplant recipients, and health care strategic plans are necessary in these vulnerable populations. The best practices contained in this expert panel report may aid to their broader implementation.

The scientific committee and expert panel finally standardized 30 best practices, including for the pretransplant period (n = 9), peritransplant period (n = 7), postransplant period (n = 8) and training and communication (n = 6). Many aspects of hospitals and units networking, telematic approaches, patient care, value-based medicine, hospitalization, and outpatient visit strategies, training for novelties and communication skills were covered. Massive vaccination has greatly improved the outcomes of the pandemic, with a decrease in severe cases requiring intensive care and a reduction in mortality.

ABSTRACT

Introducción: La infección por SARS CoV2 ha impactado de forma importante en los pacientes con trasplante renal causando una elevada mortalidad en los primeros meses de la pandemia. La reducción intencionada de la inmunosupresión se ha postulado como uno de los pilares en el manejo de la infección ante la falta de un tratamiento antiviral dirigido. Ésta se ha modificado de acuerdo con la situación clínica de los pacientes y su efecto sobre la función renal o los anticuerpos anti-HLA a medio plazo no ha sido evaluado. Objetivos: Evaluar los cambios de inmunosupresión realizados durante la infección por SARS-CoV2, así como la función renal y los anticuerpos anti-HLA de los pacientes trasplantados de riñón a los 6 meses del diagnóstico de COVID19. Material y métodos: Estudio retrospectivo, multicéntrico nacional (30 centros) de pacientes trasplantados de riñón con COVID19 desde el 01/02/20 al 31/12/20. Se recogieron las variables de la historia clínica y se incluyeron en una base de datos anonimizada. Se utilizó el programa estadístico SPSS para el análisis de resultados. Resultados: Se incluyeron 615 trasplantados renales con COVID19 (62.6% varones), con una edad media de 57.5 años. El tratamiento inmunosupresor predominante antes del COVID19 era la triple terapia con prednisona, tacrolimus y ácido micofenólico (54.6%) seguido de los regímenes con inbidores m-TOR (18.6%). Tras el diagnóstico de la infección se suspendió el ácido micofenólico en el 73.8% de los pacientes, el inhibidor m-TOR en el 41.4%, tacrolimus en el 10.5% y ciclosporina A en el 10%. A su vez, el 26.9% recibieron dexametasona y al 50.9% se les inició o aumentó la dosis de prednisona basal. La creatinina media antes del diagnóstico de COVID19, en el momento del diagnóstico y a los 6 meses fue de: 1,7±0,8;2.1±1.2 y 1,8±1 mg/dl respectivamente (p<0,001). Al 56.9% de los pacientes (N=350) se les monitorizó los anticuerpos anti-HLA. El 94% (N=329) no presentaron cambios en los anti-HLA, mientras que el 6% (N=21) los positivizaron. De entre los pacientes con anticuerpos donante-específicos post-COVID19 (N=9), a 7 pacientes (3,1%) se les había suspendido un inmunosupresor (en cinco de ellos se suspendió ácido micofenólico y en 2 tacrolimus), a 1 paciente los 2 inmunosupresores (3,4%) y al otro paciente no se le había modificado la inmunosupresión (1,1%), siendo estas diferencias no significativas. Conclusiones: El manejo de la inmunosupresión tras el diagnóstico de COVID19 se basó fundamentalmente en la suspensión de ácido micofenólico con reducciones o suspensiones muy discretas de inhibidores de calcineurina. Este manejo de la inmunosupresión no influyó en la función renal ni en cambios de los anticuerpos anti-HLA a los 6 meses del diagnóstico.

ABSTRACT

The aim was to analyze the characteristics and predictors of unfavorable outcomes in solid organ transplant recipients (SOTRs) with COVID-19. We conducted a prospective observational cohort study of 210 consecutive SOTRs hospitalized with COVID-19 in 12 Spanish centers from 21 February to 6 May 2020. Data pertaining to demographics, chronic underlying diseases, transplantation features, clinical, therapeutics, and complications were collected. The primary endpoint was a composite of intensive care unit (ICU) admission and/or death. Logistic regression analyses were performed to identify the factors associated with these unfavorable outcomes. Males accounted for 148 (70.5%) patients, the median age was 63 years, and 189 (90.0%) patients had pneumonia. Common symptoms were fever, cough, gastrointestinal disturbances, and dyspnea. The most used antiviral or host-targeted therapies included hydroxychloroquine 193/200 (96.5%), lopinavir/ritonavir 91/200 (45.5%), and tocilizumab 49/200 (24.5%). Thirty-seven (17.6%) patients required ICU admission, 12 (5.7%) suffered graft dysfunction, and 45 (21.4%) died. A shorter interval between transplantation and COVID-19 diagnosis had a negative impact on clinical prognosis. Four baseline features were identified as independent predictors of intensive care need or death: advanced age, high respiratory rate, lymphopenia, and elevated level of lactate dehydrogenase. In summary, this study presents comprehensive information on characteristics and complications of COVID-19 in hospitalized SOTRs and provides indicators available upon hospital admission for the identification of SOTRs at risk of critical disease or death, underlining the need for stringent preventative measures in the early post-transplant period.

ABSTRACT

Acute respiratory distress syndrome associated with coronavirus infection is related to a cytokine storm with large interleukin-6 (IL-6) release. The IL-6-receptor blocker tocilizumab may control the aberrant host immune response in patients with coronavirus disease 2019 (COVID-19) . In this pandemic, kidney transplant (KT) recipients are a high-risk population for severe infection and showed poor outcomes. We present a multicenter cohort study of 80 KT patients with severe COVID-19 treated with tocilizumab during hospital admission. High mortality rate was identified (32.5%), related with older age (hazard ratio [HR] 3.12 for those older than 60 years, P = .039). IL-6 and other inflammatory markers, including lactic acid dehydrogenase, ferritin, and D-dimer increased early after tocilizumab administration and their values were higher in nonsurvivors. Instead, C-reactive protein (CRP) levels decreased after tocilizumab, and this decrease positively correlated with survival (mean 12.3 mg/L in survivors vs. 33 mg/L in nonsurvivors). Each mg/L of CRP soon after tocilizumab increased the risk of death by 1% (HR 1.01 [confidence interval 1.004-1.024], P = .003). Although patients who died presented with worse respiratory situation at admission, this was not significantly different at tocilizumab administration and did not have an impact on outcome in the multivariate analysis. Tocilizumab may be effective in controlling cytokine storm in COVID-19 but randomized trials are needed.
