ABSTRACT
The objective: to study clinical and laboratory specific parameters of the COVID-19 course in patients with TB/HIV co-infection, to analyze changes in the lungs caused by COVID-19 in patients with pulmonary tuberculosis and concurrent HIV infection. Subjects and Methods. 68 HIV-infected patients aged 18-66 years old were included in the study, they all were admitted to the Novosibirsk State Regional Clinical Tuberculosis Hospital, Novosibirsk, with confirmed COVID-19 from May 2020 to May 2021. Clinical manifestations, CD4 count and HIV RNA level, and the presence of secondary infections were assessed. Results. In patients with severe and profound immunodeficiency, coronavirus infection was more often mild to moderate, and in immunocompetent patients - moderate to severe. However, patients with profound immunodeficiency were at greater risk of an adverse outcome due to lymphohematogenic progression of tuberculosis and concurrent opportunistic infections. Conclusion. When diagnosing and treating COVID-19 in patients with comorbid HIV infection and tuberculosis, it is important to consider the form of tuberculosis and CD4+ count. © 2022 New Terra Publishing House.
