Evaluation of covid-19 thorax computed tomography findings in hemodialysis patients

Abstract

Aim: Coronavirus disease 2019 (COVID-19) is an unprecedented cause of pandemics affecting all segments of society. It is not known whether hemodialysis patients form a different patient group in terms of susceptibility to COVID-19 infection or severe disease. In this study, thorax computed tomography (CT) findings were evaluated in hemodialysis patients diagnosed with COVID-19 infection during the pandemic period. Material and Methods: CT findings of 32 hemodialysis patients diagnosed with COVID-19 with real-time polymerase chain reaction or thorax CT examination were evaluated retrospectively. Radiological findings were classified as ground glass, consolidation, mixed type involvement (ground glass and consolidation), crazy paving appearance, interlobular septal thickening, nodule, halo-reverse halo finding, air bronchogram finding, subpleural curvilinear opacities and tree-in-bud views. Results: A total of 32 patients were included in the study. Twenty-one (65.6%) of the patients were male and 11 (34.4%) were female. The mean age was 67.5±8.5 years. All patients had chronic kidney failure. Thorax CT examination revealed ground-glass opacities in 14 (43.8%) patients, consolidation in 3 (9.4%) patients, and mixed type involvement (ground-glass opacities and consolidation) in 15 (46.9%) patients. The accompanying CT findings were pleural effusion in 23 (71.9%) patients, subpleural curvilinear opacities in 13 (40.6%) patients, bronchial wall thickening in 11 (34.4%) patients, lymphadenopathy in 7 (21.9%) patients, bronchiectasis in 4 (12.5%) patients and pleural thickening in 4 (12.5%) patients. Conclusion: When hemodialysis patients are infected with COVID-19 infection, they differ significantly from other COVID-19 patients in terms of symptoms, clinical course, and prognosis, as well as imaging findings.
