COVID-19 Research in Organ Transplant Recipients (CORONA)

3. januar 2021 opdateret af: John Søfteland, Vastra Gotaland Region

COVID-19 is a global major public health emergency that disproportionately affects patients with risk factors such as advanced age, heart and lung disease, diabetes, hypertension, as well as compromised immunity. Despite the recent worldwide emergence of this disease and its rapid progression to a pandemic, very little is known about the risks facing solid organ recipients. The study aims to elucidate the prevalence of symptomatic, subclinical, and asymptomatic infection in the transplanted population by assessing their immunological response to SARS-CoV-2 infection. This will be studied seroepidemiologically in the whole cohort and retrospectively in transplanted patients admitted to hospital for COVID-19.

Primary objective: to elucidate the cumulative prevalence of SARS-CoV-2 infection in the transplanted population related to symptoms and hospitalizations; to assess the magnitude of immunological response and seroconversion kinetics for COVID-19. Secondary objectives: To examine the influence of medical parameters on COVID-19 infection and immune response such as: age, comorbidities current and recent pharmacological treatment, organ transplanted, and blood type, HLA genotype.

Study design:

Part 1: Longitudinal cohort study for seroepidemiology and disease burden. Part 2: Retrospective case-series for seroconversion kinetics and clinical course assessment.

Study population:

All solid organ transplanted patients in Sweden

Detaljeret beskrivelse

The study will assess the clinical course, the outcome, and the immunologic response of organ transplant patients who have had COVID-19 (participants); The investigators aim to study the development of the immune response to COVID-19 infection to see if participants on immunosuppressive treatment, will establish sufficient immunity to protect against reinfection. The findings among participants will be compared to a suitable control population. In addition, the investigators will identify patients in our cohort who are undergoing clinically apparent infections and study their clinical course and antibody response profile in the acute phase (seroconversion).

Control groups: Other current studies with matched protocols and WHO pooled data.

Overall study design Part 1: Potential participants are all patients who have undergone solid organ transplantation (SOT) in Sweden will be invited to participate in the longitudinal cohort seroprevalence part of the study (approximately 1000 patients will be included). This part of the study is a single-center longitudinal cohort study that will evaluate the development of antibodies against SARS-CoV-2 in solid organ recipients at all stages after transplantation and study their disease course, complications, and death rate.

The study has been designed to follow the best practices outlined by the WHO in their recent guidelines entitled "Population-based age-stratified seroepidemiological investigation protocol for COVID-19 virus infection COVID-19 v1.1". This will allow a comparison of symptoms, outcomes, case fatality rate, as well as antibody titers and prevalence, with other relevant control groups. Participant enrollment will be allowed for a maximum of 2 years. The duration of the study will be two years from enrollment. The last participant will thus complete follow-up a maximum of 4 years after the commencement of the study Part 2: The investigators will also do a retrospective assessment of transplanted patients in Sweden with PCR confirmed COVID-19.
