Этот термин используется для обозначения симптомов новой коронавирусной инфекции, которые длятся более 4 недель, но менее 12 недель с начала заболевания. Самыми частыми проявлениями являются одышка, кашель, общая слабость. В группу риска длительного течения COVID-19 входят пациенты с иммунодефицитом. Одной из причин длительного сохранения симптомов является персистенция вируса в организме. Однако в 30–40% случаев результаты ПЦР-теста на SARS-CoV-2 оказываются отрицательными, что затрудняет постановку диагноза. Кроме того, у пациентов с иммунодефицитом на фоне Long-COVID могут возникать оппортунистические инфекции, вызванные реактивированной условно-патогенной микрофлорой на фоне лимфопении. Представленный клинический пример демонстрирует случай Long-COVID инфекции, осложненной развитием пневмоцистной пневмонии, у пациентки с фолликулярной лимфомой. Своевременная постановка диагноза и начало специфического лечения позволили стабилизировать состояние пациентки и не допустить фульминантного течения пневмоцистной инфекции.</p></abstract><trans-abstract xml:lang="en"><p>The COVID-19 pandemic has led to global consequences, including Long-COVID. This term is used to refer to the symptoms of a new coronavirus infection that last more than 4 weeks, but less than 12 weeks from the onset of the disease. The most common symptoms are shortness of breath, cough, and general weakness. The risk group for the long-term course of COVID-19 includes patients with immunodeficiency. One of the reasons for the long-term persistence of symptoms is the persistence of the virus in the body. However, in 30–40% of cases, the results of the SARS-CoV-2 test turn out to be negative, which makes it difficult to make a diagnosis. In addition, patients with immunodeficiency against Long-COVID may develop opportunistic infections caused by reactivated opportunistic microflora against the background of lymphopenia. The presented clinical example demonstrates a case of Long-COVID infection complicated by the development of pneumocystis pneumonia in a patient with follicular lymphoma. Timely diagnosis and initiation of specific treatment made it possible to stabilize the patient’s condition and prevent the fulminant course of pneumocystis infection.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>Long-COVID</kwd><kwd>фолликулярная лимфома</kwd><kwd>пневмоцистная пневмония</kwd><kwd>котримоксазол</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>Long-COVID</kwd><kwd>follicular lymphoma</kwd><kwd>pneumocystis pneumonia</kwd><kwd>co-trimoxazole</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">https://data.who.int/dashboards/covid19/cases?n=c</mixed-citation><mixed-citation xml:lang="en">https://data.who.int/dashboards/covid19/cases?n=c</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Здравоохранение в России. 2023: Стат.сб./Росстат. – М., 2023. – 181 с.</mixed-citation><mixed-citation xml:lang="en">Healthcare in Russia. 2023: Stat.sat./Rosstat, Moscow, 2023, 181 p.</mixed-citation></citation-alternatives></ref><ref id="cit3"><label>3</label><citation-alternatives><mixed-citation xml:lang="ru">Gao Y.D., Ding M. et al.
