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.
A separate problem is the treatment of hypertension in patients with COVID-19. The presence of a history of hypertension in patients with COVID-19 was associated with a more severe course of infection, in contrast to patients who did not have hypertension. According to modern concepts, during the COVID-19 pandemic, patients with hypertension should carefully monitor their blood pressure levels and take constantly prescribed medications. This also applies to the use of so-called blockers of the renin-angiotensin system for the treatment of patients with hypertension: angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers. A number of recent studies show that these groups of drugs not only do not increase the risk of infection with the virus, but also significantly improve the course of coronavirus disease.
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.
Реагирование на такие эпидемические вызовы очень сложны как организационно, так и финансово. Результат оценивается с течением времени при хорошо организованном эпидемиологическом надзоре. Согласно утвержденному плану реагирования на вспышку полиомиелита, возникшему в начале октября 2021 г., удалось только 1 февраля 2022 г. начать 1-й тур кампании. Он должен был длиться 3 недели и имел целью вакцинировать ИПВ 140 тыс. детей в возрасте от 6 мес. до 6 лет, пропустивших вакцинацию согласно Календарю. Практически к концу 3-й недели 1-го тура по состоянию на 18.02.2022 г. было провакцинировано лишь 28% детей от запланированного количества. Поэтому решили продлить 1-й тур еще дополнительно на 2 недели, что снова не было исполнено в связи с началом войны. Таким образом, фактически реагирования на вспышки полиомиелита не произошло.
