If a patient tests positive for SARS-CoV-2 and/or develops COVID-19, discontinuation of biologics should be considered until the patient clears the infection.
JAK inhibitors (tofacitinib and others) selectively affect the intracellular JAK/STAT signaling system, which mediates the action of many cytokines involved in the pathogenesis of ulcerative colitis. Unlike genetically engineered biological drugs, inhibition
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.
Considering that a similar picture took place in previous years, in Ukraine there was an accumulation of a layer susceptible to poliomyelitis among the child population. In addition, since April 2016, the oral (live) polio vaccine (OPV), which is used in Ukraine, since the 3rd vaccination, does not contain type 2 poliovirus (two-component OPV, which is now used worldwide, contains only polioviruses). ). type ov1 and 3). This also contributes to a decrease in both individual and population immunity to type 2 poliovirus. The result was an outbreak of poliomyelitis caused by vaccine-derived type 2 poliovirus (a vaccine-derived virus that acquired neurovirulent properties during circulation in a low immune population.). There was no adequate response to this outbreak, namely additional vaccination rounds for children under 6 years of age to stop the circulation of the vaccine-related virus. In January 2022, a new outbreak emerged.
