Although COVID-19 is mostly a respiratory disease, it can cause kidney and multiorgan failure in some cases. We believe that by sharing information about the course and effects of COVID-19 infection in kidney transplant recipients receiving long-term immunosuppressive therapy our understanding will improve. Materials and Methods: Between March 2020 and October 2021, COVID-19 was researched in kidney transplant recipients under the age of 20 years who were followed at the Baskent University Transplantation Center. We documented the clinical characteristics and prognosis of pediatric kidney transplant recipients with COVID-19 disease. Results: Our study group included 23 patients with COVID-19 infection from 215 pediatric kidney transplant recipients. The mean age of the patients was 14.6 +/- 4.7 years; there were 9 female patients. The mean follow-up time posttransplant was 62.3 +/- 43.2 months. In 13 patients (56.5%), fever was the most frequent symptom. Most patients (n = 18, 78%) had minor symptoms and recovered completely after receiving supportive treatment. Four patients (17%) required hospitalization. One was diagnosed with COVID-19 infection 1 week after being treated with rituximab for acute antibody-mediated rejection. That patient died because of significant lung disease and multiorgan failure. Conclusions: Despite the fact that most of our pediatric transplant recipients had mild symptoms of COVID-19, we believe that particular caution should be observed in patients who have recently received intensive immunosuppressive medications. As a result of potential new vaccines, national immunization programs, and the emergence of novel virus strains, the clinical picture may change in the future. We believe that, as information sharing increases, we will learn more about COVID-19 in renal transplant recipients.Item Cytomegalovirus Viremia in Solid-Organ Transplant Patients in the First Year After Transplantation(2022) Erol, Cigdem; Akdur, Aydincan; Arslan, Hande; Haberal, Mehmet; https://orcid.org/0000-0002-2535-2534; https://orcid.org/0000-0002-3462-7632; 35384821; AAJ-1219-2021; AAJ-8097-2021Objectives: Cytomegalovirus infection is an important problem for transplantation. Although effective antivirals for prophylaxis or preemptive therapy have reduced the severity and consequences of infection, cytomegalovirus viremia and cytomegalovirusrelated disease are still matters for patients and for graft survival. The aim of our study was to determine the frequency of cytomegalovirus infections during the first year after transplant. Materials and Methods: In this study, we analyzed the data of 252 liver and kidney transplant patients who had procedures between May 2016 and May 2020. Demographic and laboratory data of patients were recorded retrospectively and analyzed with the SPSS version 25 statistical program. Results: Our study included 35 liver (14%) and 217 kidney transplant recipients. The ratio of male to female was 3.8, and the median age was 41 years (range, 18-71 years). In our study group, there were 32 patients (12.7%) with cytomegalovirus DNAemia, 13 patients (5%) with cytomegalovirus syndrome, and 6 patients (2.4%) with cytomegalovirus endorgan diseases. Four patients were diagnosed with gastrointestinal disease with histopathology, and 2 patients were diagnosed with cytomegalovirus pneumonia with bronchoscopy and radiology. The mortality rate was 0.8% in the first year. Conclusions: Cytomegalovirus reactivations in the first year after transplant play a critical role on graft survival in solid- organ transplant. Regular follow-up of cytomegalovirus DNAemia is crucial for modifying prophylactic and preemptive antiviral regimens.
