COVID-19 and viral dermal diseases in patients after renal transplantation

Background. COVID-19 in solid organ transplant recipients is usually characterized by more severe disease course and is often associated with life-threatening complications. Identification of additional factors that may affect the risk and severity of the new coronavirus infection could have a significant impact on choosing a management strategy for renal graft recipients. Aim. To evaluate the possibility of cross-immunity between skin manifestations of viral etiology and COVID-19. Material and methods: From May 2020 to February 2021 we examined 180 renal graft recipients with a history of transplantation from 2 months to 26.5 years. All patients were categorized into two groups: group I, those who had confirmed moderate or severe COVID-19 disease and group II, and those without any history of clinical manifestations of the new coronavirus infection (including those with potentially asymptomatic disease). During the study period which lasted for 71 months on average (range, 2 to 318 months), laboratory workup was performed in all patients (on average, twice): dermatological examination and detection of serum antibodies to herpes simplex virus 1, 2, cytomegalovirus, Epstein-Barr virus, SARS-CoV-2. Results: In recipients with HPV-associated skin manifestations, the incidence of COVID-19 was significantly lower than in recipients who did not have them - 30.4 and 50.0%, respectively (p=0.011). The incidence of new coronavirus infection did not differ in the groups of patients with cutaneous manifestations caused by herpes simplex viruses type 1 and 2, and without them. Among recipients with Epstein-Barr virus seropositivity, there were significantly fewer cases of COVID-19 compared to seronegative patients - 26.2 and 54.8%, respectively (p=0.0002). Conclusion: HPV-associated dermal manifestations of serum EBV-seropositivity in renal graft recipients is associated with lower incidence of moderate and severe COVID-19. Further studies are needed to confirm the possibility of cross-immunity against SARS-Cov-2 with other infections
