Introduction & Objectives: The COVID-19 pandemic has made adjustments both in the general life of people and in the medical practice of doctors of many specialties. In addition, doctors - dermatovenerologists at daily appointments increasingly consult users with drug-induced rashes that occurred after treatment of COVID-19. Medicinal lesions of the skin with a viral coronavirus infection are necessarily associated with a large number of drugs of various pharmacological groups prescribed to the patient, which, interacting, can have a toxic effect on human protection. One of the most important manifestations of the toxic effect of drugs on the human body is toxic epidermal necrolysis (TEN).
Purpose The research method was to analyze the anamnestic data from TEN and characterize the amino acid composition of the blood serum of such patients with damage to more than 50% of the skin area.
Materials & Methods: 6 used TENs were under our observation, during periods of various diseases (initial, acute) that had undergone COVID-19, the area of the affected skin was determined by the rule of “nines”, the amino acid composition of blood serum was determined by the method of thin-layer two-dimensional chromatography.
