Popis: COVID-19 is a highly transmissible disease with severe course especially in patients with nephrogenic hypertensive disease and chronic kidney disease due to a higher incidence of all-type infections than in the general population. The aim of the study is to describe a clinical case of SARS-CoV-2 infection complicated by nephrogenic pulmonary edema and COVID-associated pneumonitis, alveolitis. Description of the case. Patient K.S., born in 1975, was hospitalized 24 hours after symptom onset at emergency hospital due to complaints of increased blood pressure up to 180200/110120 mm Hg, temperature up to 38.7C, dry cough, feeling of heaviness in the chest, change in urine color. PCR smear for SARS-CoV-2 was positive. Computed tomography revealed a pattern of bilateral COVID-associated pneumonitis, alveolitis, with 75% involvement. The electrocardiogram revealed signs of left ventricular myocardial hypertrophy. Ultrasound examination showed numerous cysts in the kidneys. Urinalysis at admission: leukocytes 499, erythrocytes 386. Glomerular filtration rate (CKD-EPI: 29 ml/min/1.73 m2) and corresponds to stage IV of chronic kidney disease. Coagulogram: fibrinogen: 32.3 (1.64.0) g/l, D-dimer: 663 (0250). Despite the treatment, the patients condition worsened, the phenomena of cardiopulmonary and renal insufficiency increased, which led to a fatal outcome. During a virological study of sectional material: SARS-CoV-2 coronavirus RNA was found in the lung and kidneys. Signs of bilateral COVID-associated pneumonitis, alveolitis with diffuse cellular infiltrates in combination with changes in the alveolar apparatus, signs of pulmonary edema were revealed. Heart-related signs swelling of the interstitium, fragmented muscle fibers, some of them hypertrophied, a wave-like deformation of cardiomyocytes, blurring of the transverse striation. Arteries with thickened sclerosed walls. In the kidneys diffuse damage to the proximal tubules of the nephron with areas of cortical and proximal necronephrosis, areas of fibrinoid swelling. Conclusion. The cause of death of a 45-year-old patient was a severe course of bilateral COVID-associated pneumonitis, alveolitis, which contributed to the development of renal medullary hypoxia and type 1 cardiorenal syndrome, which led to early nephrogenic pulmonary edema.
