Одним из характерных лабораторных признаков, отражающих тяжесть течения COVID-19, является повышение уровня С-реактивного белка (СРБ). Однако в некоторых случаях уровень СРБ в течение длительного времени может оставаться в пределах нормальных значений, несмотря на присутствие других признаков тяжелого течения заболевания. В статье представлены два клинических наблюдения тяжелого течения двусторонней пневмонии, ассоциированной с COVID-19, у пациентов с поздним повышением уровня СРБ. Такие больные могут представлять определенные трудности при оценке тяжести течения и подборе патогенетической терапии.</p></abstract><trans-abstract xml:lang="en"><p>Clinical signs of COVID-19 infection are non-specific and diagnosis is typically based on comprehensive evaluation of the patient’s history, clinical status, radiological and laboratory findings. A common finding in COVID-19 patients is increased C-reactive protein (CRP), though in some patients, CRP remains within normal range notwithstanding the presence of other criteria of severe disease. We describe two clinical cases of COVID-19 with severe bilateral pneumonia and late increase in CRP. Similar cases re quite challenging for making the diagnosis and indicating the antiinflammatory therapy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>С-реактивный белок</kwd><kwd>«цитокиновый шторм»</kwd><kwd>коронавирусная инфекция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>C-reactive protein</kwd><kwd>“cytokine storm”</kwd><kwd>coronavirus infection</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ponti G., Maccaferri M., Ruini C. et al.
