Even after two years of the Coronavirus Disease 2019 (COVID-19) pandemic, despite known risk factors, we are still unable to predict the severity of the infection in specific patients. Due to the contradictory data, the protective role of immunosuppression in preventing the severe course of the infection remains uncertain. Therefore, we want to discuss the influence of several immunosuppressive factors on the COVID-19 pattern in children, based on two case reports regarding 17-year-old boys with other immunosuppressive factors and a completely different course of the disease. The first patient suffered from AIDS, syphilis and primary central nervous system B-cell lymphoma, treated with radiotherapy. He experienced a light path of the infection, presenting only periodically appearing cough with no X-ray inflammatory changes. Nevertheless, due to the risk of severe COVID-19 and transient hypoxia, remdesivir was administered. He remained in a generally good condition and his follow-up did not reveal any noticeable complications. The second patient was characterised by Down syndrome, obesity, polyarteritis nodosa and chronic immunosuppressive therapy. He developed massive pneumonia, required treatment in the intensive care unit with the use of mechanical ventilation, remdesivir and anakinra. Despite the initial improvement of his general condition, including the degree of lung involvement and respiratory function, he developed an intracerebral haemorrhage, leading to brain herniation and ultimately death. In conclusion, HIV infection, oncological and immunosuppressive treatment do not seem to predispose to the severe course of COVID-19, whereas Down syndrome and obesity do.
