Pulmonary manifestations of hemodialysis patients combined with COVID-19 based on computer scan score and blood routine / 基础医学与临床

ABSTRACT

Objective To investigate the characteristics of blood routine,chest computed tomography(CT)imaging and short-term evolution of hemodialysis patients infected with Omicron variant of severe acute respiratory syndrom coronavirus 2(SARS-CoV-2).Methods A total of 204 patients diagnosed with Omicron variant infection in the First Hospital of Hohhot from September 2022 to September 2023 were retrospectively reviewed.Among them,89 patients with end-stage renal disease(ESRD)who were receiving hemodialysis were included in the hemo-dialysis group.The remaining 115 patients were control group,and the first blood routine results chest com-puted tomography(CT)imaging data were observed.Thirty-four patients in the hemodialysis group and 29 patients in the control group had complete pulmonary CT imaging data on the day of admission,5-6 days and 10-12 days after admission.The characteristics and chest CT scores of all cases were analyzed.Results 1)The percentage of monocytes,neutrophils,neutrophil/lymphocyte ratio and chest CT score of the hemo-dialysis group were higher than those of the control group,while the white blood cells,lymphocytes and lymphocyte percentage were lower than those of the control group.2)The positive rate of first chest CT was 49.4%in hemo-dialysis group and 35.7%in control group.3)The chest CT scores of the hemo-dialysis group and the control group on day 5 and day 6 were higher than those of first check.Chest CT was reexamined on days 10-12,and scores were higher in the hemo-dial-ysis group than in the control group.Conclusions Hemo-dialysis patients with COVID-19 have higher blood routine indexes,higher positive rate of lung CT and slower absorption than non-hemodialysis patients.
