Old Age, High NWR, and PCT may Predict Mortality in Hemodialysis Patients with COVID-19, suggests study
Old Age, High NWR, and PCT may Predict Mortality in Hemodialysis Patients with COVID-19 suggests a new study published in the BMC Nephrology.
The globally widespread coronavirus disease of 2019 (COVID-19) was first detected in Wuhan province, China, in December 2019 and is caused by the severe acute respiratory syndrome coronavirus. Older hemodialysis patients and those with obvious comorbidities are reported to be more susceptible to severe viral and bacterial respiratory infections, as has been shown with COVID-19.
Exploring the risk factors for mortality of hemodialysis patients undergoing COVID-19 and the changes in mortality before and after the opening of the epidemic in northern Hunan province, China. They analyzed 230 hemodialysis patients with COVID-19 in the Yiyang Central Hospital from November 01, 2022 to February 28, 2023. Demographic data, laboratory data and public diseases were collected. Cox regression analysis was used to identify risk factors and independent predictors of mortality. The receiver operating characteristic (ROC) curve was used to determine the diagnostic value of risk factors in hemodialysis COVID-19 patients.
Results: The average duration of the disease was 12.53 days. The mortality rate in our cohort was 28.70%. Independent predictors of mortality in our cohort were: age (hazard ratio [HR] 1.09; 95% confidence interval [CI], 1.05–1.14; P < 0.001), elevated procalcitonin (PCT) levels, and higher white blood cell-neutrophil ratio (NWR). Areas under the ROC curve (AUC) for age, NWR, PCT, and age*NWR were 0.70, 0.82, 0.64, and 0.89.
They discovered that old age, and high levels of NWR and PCT might be predictors of mortality, reported the causes and prognostic predictors of mortality in hemodialysis populations with COVID-19 from northern Hunan, China.
