Skin lesions in coronavirus infection caused by the SARS-CoV-2 virus are divided into seven categories. The first category includes skin angiitis caused directly by COVID-19 infection, against which the walls of small vessels of the dermis are damaged by immune complexes circulating in the blood. Angiitis is localized on the skin of the upper and lower extremities. They look like frostbite, painful, itchy. Such manifestations usually occur in young patients with a mild course of the disease, appear in the late stages and last about 12 days. The second category includes papular-vesicular rashes, which are characterized by acute clinical manifestations in the form of chickenpox, more similar to prickly heat, occurring against a background of high fever and increased sweating.
Именно переход на использование в Украине ИПВ для всех доз Календаря прививок должен быть ближайшей задачей по вакцинопрофилактике. Для этого можно использовать несколько механизмов, включая гуманитарную помощь, заключение планируемых прямых договоров с производителями вакцин исходя из потребностей необходимого состава вакцин согласно Календарю, в частности с учетом существования современных комбинированных вакцин с ИПВ, которые могут быть использованы и в более старшем возрасте. При отсутствии комбинированных вакцин с ИПВ можно использовать ИПВ в качестве моновакцины.
5-ASA preparations have very weak immunosuppressive activity. There are no reports that these drugs are associated with an increased risk of infection, and studies evaluating the safety profile of 5-ASA do not show an increased risk of serious or opportunistic infections. Treatment with 5-ASA should be continued without concern for an increased risk of infection or severe COVID-19. If the patient is in contact with a patient with COVID-19 or develops COVID-19, treatment with 5-ASA should be continued.
The use of thiopurine (azathioprine and mercaptopurine) reduces the immune response to viruses, which is associated with an increased risk of opportunistic infections. There is limited evidence that they increase the risk of respiratory infections. The risks and benefits should be considered, but most patients can continue on a stable dose. In patients in stable remission, elderly patients and in the presence of concomitant pathology, it is recommended to stop taking thiopurine. During a pandemic, it is recommended to avoid starting thiopurine or increasing the dose, which will allow patients to avoid potential side effects. If the patient is in contact with a COVID-19 person, temporary withdrawal of thiopurine for 2 weeks should be considered. If a patient tests positive for SARS-CoV-2 and/or develops COVID-19, temporary discontinuation of thiopurine may be recommended until the patient clears the infection.
