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.
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.
In 2021, in Ukraine, vaccination coverage rates for children under 1 year of age against such infections as tuberculosis, measles, whooping cough, diphtheria, poliomyelitis, hepatitis B, etc. ranged from 78% to 80.1% (with the required level >90 %), which is undoubtedly not enough to recognize the epidemic situation under control. In particular, this figure for 3 vaccinations against polio at the age of up to 1 year was 80.1%, 5 vaccinations at the age of 6 years received only 78.4% of children. At the same time, vaccination coverage rates varied widely across regions. In 12 regions, among children under 1 year old, they were <80% and ranged from 68.5% to 73.9%, and among children under 18 months. (4 vaccinations) - 66% to 73%. That is, almost 20-30% of children did not receive routine vaccination against poliomyelitis due to age in the above target groups, subject to vaccination according to the Immunization Schedule.
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.
