(583) Sotrovimab in Heart Transplant Recipients with Covid-19 in the Omicron Era: A National Transplant Center Experience

PURPOSE: Early use of anti-SARS-CoV-2 monoclonal antibodies has shown to be a safe option to reduce hospitalization and death in solid organ transplant recipients with COVID-19. Real world data regarding sotrovimab in heart transplant (HT) recipients is scarce. We aim to describe our experience in terms of safety and outcomes in this group. METHODS: Consecutive HT recipients from our center with confirmed SARS-CoV-2 Omicron variant who received intravenous sotrovimab infusion between January and April 2022 were enrolled in this observational study. Clinical data was recorded including the first 24 hours post infusion, as well as 1-month and 3-month follow-ups. RESULTS: A total of 29 HT recipients with SARS-CoV-2 infection who received sotrovimab were enrolled [median age 53 (IQR 36, 62), 52% female]. Baseline characteristics are shown in Table 1. The median time since symptom onset was 2 (1,3) days, and 86% of patients had previously received ≥3 doses of COVID-19 vaccine. No acute infusion-related reactions were reported. A total of five patients were admitted (17%), 3 of them with COVID-19 pneumonitis, receiving high-dose steroids. Bacterial superinfection was reported in 4 patients. Neither invasive mechanical ventilation nor ICU care were required, and no in-hospital deaths were recorded. Hospitalized patients had more comorbidities [diabetes (40 vs 13%, p 0.13), hyperlipidemia (80 vs 29%, p 0.03), advanced chronic kidney disease (100 vs 38%, p 0.01), leucopenia (40 vs 4%, p 0.02), and anemia (100 vs 46%, 0.03)], compared to non-hospitalized patients. Over a median follow-up of 111 (86, 131) days, there were 2 cases of COVID-19 reinfection and 6 non-COVID-19-related readmissions. No episodes of acute rejection, new onset graft dysfunction or death were registered. CONCLUSION: In our series, the early use of sotrovimab in HT recipients with COVID-19 was safe. No COVID-19-related deaths were recorded, hospitalization rate was low and more frequent in patients with prior chronic comorbidities.
