    Aim. An efficacy assessment of steroid therapy in SARS-CoV-2 patients aged over 50 years with lung damage over 50 % (grade 3–4).Materials and methods. A retrospective study of 158 SARS-CoV-2 patients hospitalised in April—June 2020 was conducted under the inclusion criteria: age over 50 years, chest computed tomography (CT) for COVID-19-asso-ciated pneumonia, C-reactive protein (CRP) >50 mg/L, anticoagulant therapy, no contraindications to steroids, no biologic therapy. Cohort 1 patients (n = 96) received dexamethasone 4–12 mg/day, cohort 2 (n = 62) — a standard non-dexamethasone therapy.Results. Dexamethasone treatment associated with a significant alleviation of COVID-19-associated pneumonia in CT score (p = 0.001), reduced fibrinogen (p = 0.001), a trend to CRP reduction by day 8–10 and lower demand for oxygen therapy, including ventilatory support (p = 0.001). Mortality rate was 19.8 and 75.8 % in cohorts 1 and 2, respectively (p = 0.001).Conclusion. Dexamethasone therapy 4–12 mg/day in SARS-CoV-2 patients aged 50+ years with grade 3–4 CT changes receiving LMWH from start of hospitalisation significantly improved CT scores and reduced mortality

    The objective: assessment of changes in the parameters of complete blood count, clinical urine tests, and blood chemistry during chemotherapy of patients with MDR/XDR pulmonary tuberculosis receiving the short-course regimen containing bedaquiline, pretomanid, and linezolid (B-Pa-L).Subjects and Methods. 18 patients with MDR/pre-XDR/XDR pulmonary tuberculosis were enrolled into the study. They all received treatment at Central Tuberculosis Research Institute from 2015 to 2022.Results. In the course of chemotherapy of these patients, changes in laboratory test results were noted at different times. Abnormal changes in complete blood count were detected in 10/18 (55,6%) patients during chemotherapy for the 1st time. Hemoglobin levels, erythrocyte and leukocyte counts decreased. Hematuria and bacteriuria were detected by clinical urine test. Proteinuria was observed in almost in half of the patients. Elevated serum potassium level was frequently noted. Blood chemistry demonstrated elevated levels of ALT and AST, which is typical of cytolytic effect on hepatocytes of drugs within chemotherapy. In most cases, all above abnormalities were degree 1 of toxicity and resolved within 2-4 weeks after they were detected. Abnormalities in grade 2-3 of toxicity were mainly observed in patients receiving linezolid at the dose of 1200 mg/day. In most cases, the above abnormalities were detected during the first 4 weeks of chemotherapy.Цель исследования: оценка изменений показателей клинических анализов крови и мочи, биохимического анализа крови в процессе химиотерапии больных МЛУ/ШЛУ ТБ легких коротким режимом по схеме «бедаквилин, претоманид, линезолид» (B-Pa-L).Материалы и методы. В исследование включено 18 больных МЛУ/пре-ШЛУ/ШЛУ туберкулезом легких, находившихся на лечении в ФГБНУ «ЦНИИТ» в период с 2015 по 2022 г.Результаты. В процессе химиотерапии (ХТ) этих пациентов в разные сроки были отмечены изменения в лабораторных анализах. В клиническом анализе крови патологические изменения у 10/18 (55,6%) пациентов были впервые обнаружены в процессе ХТ. Наблюдалось снижение уровня гемоглобина, эритроцитов, лейкоцитов. В клиническом анализе мочи обнаруживалась гематурия, бактериурия. Протеинурия наблюдалась почти у половины пациентов. Также установлено частое повышение уровня калия в сыворотке крови. В биохимическом анализе крови фиксировалось повышение активности ферментов АЛТ и АСТ, что характерно для цитолитического эффекта на гепатоциты химиопрепаратов. Все вышеуказанные изменения в большинстве случаев были 1 степени токсичности и возвращались в пределы нормы в течение 2-4 недель после выявления. Изменения 2-3 степени токсичности в основном наблюдались у пациентов, получавших линезолид в дозе 1200 мг/сут. В большинстве случаев вышеуказанные изменения выявлялись в течение первых 4 недель ХТ
