Treatment of Pediatric Patients With COVID Infection After Heart Transplantation

The COVID-19 pandemic that has been ongoing since the beginning of 2020 has forced health care into a difficult struggle for wellness and the lives of patients. International data and our observations show that the course of the disease in these patients is different than in the general population. Symptoms depend on the immunosuppression and severity of viremia. The period of viral replication is much longer. Our observations include 4 pediatric patients post heart transplant who became infected with the coronavirus. One patient was infected in the hospital during perioperative period. Two others required hospitalization because of the severity of symptoms, and 1 was treated on an outpatient basis. The applied treatment included the reduction of immunosuppression, low-molecular-weight heparin, amantadine or remdesivir, steroids, and supplementation with zinc and vitamins C and D. Based on the antigenic tests performed, we determined the period of active replication to be 3 to 8 weeks from the onset of the first symptoms.
