On March 11, 2020, the World Health Organization declared the novel severe respiratory syndrome coronavirus (SARS-CoV-2) a pandemic. The number of cases worldwide is constantly growing, the infection is a serious threat to health, especially in the case of old age, immunodeficiency and the presence of concomitant diseases. There are now a growing number of reports and preliminary observations indicating that the COVID-19 virus can also infect the skin. Skin lesions ranging from "covid fingers" to hives can be potential signs of coronavirus. The flow of information about the skin manifestations of coronavirus infection prompts the development of a classification of these lesions.
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.

Ингибиторы JAK ( тофацитиниб и др.) селективно влияют на внутриклеточную сигнальную систему JAK/STAT, опосредующую действие многих цитокинов, участвующих в патогенезе неспецифического язвенного колита. В отличие от генно-инженерных биологических препаратов, ингибиторы янус-киназа представляют собой низкомолекулярные синтетические средства, предназначенные для перорального приема. Тофацитиниб рекомендуют назначать пациентам с тяжелым и среднетяжелым течением неспецифического язвенного колита. Ингибиторы JAK могут нарушать вирусный иммунитет. Рекомендуется использовать низкую эффективную дозу для поддержания ремиссии: по возможности 5 мг, вместо 10 мг, два раза в день. Избегайте применения тофацитиниба во время пандемии, если нет других альтернатив. Это позволит пациентам избежать возможных побочных эффектов и частого наблюдения за патологией.
