Abstract

Purpose - to analyze practice cases with an atypical course associated with comorbid pathology; to acquaint pediatricians and family physicians with the diagnostic search algorithm. The article summarizes literature data, and describes a clinical case of erythema infectiousum in combination with Raynaud's phenomenon, which occurred in a 9-year-old child І. with coronavirus disease in anamnesis. It was established that the nature of the pathological changes: periodic hyperemia of the cheeks and auricles, “slapped cheeks”, and, at the same time, palleness of the nasolabial triangle, a pronounced change in color, marbling of the skin on the limbs and on the buttocks, with a lacy pattern of vessels, which are provoked by exposure to cold air or psycho-emotional excitement, clearly indicate both the manifestations of parvovirus infection, and the Raynaud's phenomenon mentioned above. On the other hand, post-covid syndrome is also often accompanied by non-specific changes in the skin and its derivatives (up to 20.4% of cases) in the form of urticaria, erythema, and frostbite. In the same group of patients, there are maculopapular rashes and livedo reticularis, those could be Conclusions. During the pandemic of coronavirus infection, the issues of comorbid pathological conditions in pediatrics, which have a blurred clinical picture, an atypical course, common links of pathogenesis, in particular microcirculation disorders, and require an interdisciplinary approach to the management of these diseases, rehabilitation measures, are becoming more and more relevant. interpreted both as a manifestation of systemic vasculitis, and as independent disease. Thus, the patient was diagnosed with infectious erythema caused by parvovirus B19 in combination with Raynaud's phenomenon, probably caused by a history of coronavirus disease. The multicomponent nature of the patient's symptoms is highlighted, and the diagnostic search algorithm is shown. The study was conducted in accordance with the principles of the Declaration of Helsinki. An informed parental consent was obtained for the study in children.
