A case of severe COVID-19 in a patient with progressive fibrosing interstitial lung disease

Interstitial lung diseases (ILDs) is a wide group of diffuse parenchymal lung diseases that can lead to interstitial pulmonary fibrosis. Clinical course of all ILDs, in particular with chronic fibrosing phenotype, can be complicated by an acute exacerbation caused by infection. Today, data about clinical course of COVID-19 in patients with progressive interstitial lung diseases is limited. In this case we described the course of COVID-19 infection in a patient with an interstitial pneumonia with autoimmune features (IPAF) and a progressive pulmonary fibrosis (PPF). We also discussed the typical features of COVID-19 in this population and the directions for further research. Copyright © 2022 Medical Education. All rights reserved.

[Organizing pneumonia as a pulmonary manifestation of post-COVID syndrome: features of diagnosis and treatment].

Treatment of patients with long-term persistent symptoms after COVID-19 is an urgent problem for clinicians around the world. One of the most significant manifestations of post-COVID-19 syndrome is organizing pneumonia that is usually treat with corticosteroids. The paper presents a clinical case of typical course of post-COVID-19 organizing pneumonia in a patient without previous lung disease. Risk factors, diagnostic methods and treatment options in this group of patients are also discuss.

[Risk factors of kidney injury in patients with COVID-19].

AIM: To determine the incidence and risk factors of acute kidney injury (AKI) in Russian cohort of patients with COVID-19. MATERIALS AND METHODS: We included 315 patients, who were hospitalized with COVID-19 from October 2020 till February 2021. The diagnosis was established on the basis of the positive SARS-CoV-2 swab test and/or typical radiologic findings on CT scans. RESULTS: AKI complicated the clinical course in 92 (29.21%) cases. The independent risk factors of AKI were female sex, underline chronic kidney disease and the highest level of C-reactive protein during hospitalization. In the general group of patients were 41 (13%) lethal cases, in the group with AKI 32 (34.8%). Compared with those without AKI, patients with AKI had 4.065 (95% confidence interval 2.154 to 7.671) times the odds of death. Respiratory support, the highest serum creatinine and glucose levels appeared to be the risk factors of death among patients with AKI in the multivariable Cox regression. CONCLUSION: The clinical course of COVID-19 was complicated by AKI in 29% cases. The independent risk factors of AKI in patients with COVID-19 are underline chronic kidney disease, circulatory disorder and the highest level of C-reactive protein during hospitalization.

[Risk factors for the early development of septic shock in patients with severe COVID-19].

AIM: In a retrospective study, we evaluated factors associated with the early development of septic shock in patients with severe COVID-19. MATERIALS AND METHODS: We collected medical records of the intensive care unit patients submitted by the local COVID-19 hospitals across Russia to the Federal Center for the Critical Care at the Sechenov First Moscow State Medical University (Sechenov University). Septic shock in crticially ill patients requiring mechanical ventilation was defined as a need in vasopressors to maintain blood pressure. RESULTS: We studied 1078 patients with severe COVID-19 who were admitted to the intensive care units for respiratory support. There were 611 males and 467 females. The mean age was 61.013.7 years. Five hundred twenty five medical records (48.7%) were received from the Moscow hospitals, 159 (14.7%) from the Moscow region, and 394 (36.5%) from the hospitals located in 58 regions of the Russian Federation. In 613 (56.9%) patients, diagnosis of SARS-CoV-2 infection was confirmed by PCR, and in the other cases it was established on the basis of the clinical picture and the results of the chest CT scan. Septic shock developed in 214 (19.9%) of 1078 patients. In the logistic regression model, the risk of septic shock in patients older than 50 years was higher than in patients of a younger age (OR 2.34; 95% CI 1.533.67; p0.0001). In patients with more severe SARS-CoV-2 infection, there was an increase in the prevalence of cardiovascular diseases, including coronary heart disease and atrial fibrillation, type 2 diabetes and malignant tumors. The risk of septic shock in patients with three or more concomitant diseases was higher than in patients without any concomitant chronic diseases (OR 1.76; 95% CI 1.762.70). CONCLUSION: The risk of septic shock in patients with acute respiratory distress syndrome induced by SARS-CoV-2 is higher in patients older than 50 years with concomitant diseases, although a severe course of the disease is also possible in younger patients without any concomitant disorders.
