“…While after balancing the confounding factors, the logistic regression showed that D-dimer > 0.83 µg/ml could not be used as an independent predictor of disease risk in this study (OR = 1.209; 95%CI = 0.626-2.334; p = 0.571). In a dynamic study of hematological parameters in patients with COVID-19, the D-dimer of the severe group was higher than the non-severe group on days 1, 7 and 14 (p < 0.05) [24]. This suggests that due to different admission times, the ability of D-dimer to predict disease risk may be weakened.…”

Background: To explore the significance of neutrophil-to-lymphocyte ratio (NLR), lactate dehydrogenase (LDH), D-dimer and CT score in evaluating the severity and prognosis of coronavirus disease – 2019 (COVID-19) in two centers of Hubei, China.Methods: A total of 432 patients with laboratory confirmed COVID-19 were retrospectively enrolled and divided into non-severe and severe groups. The baseline data, laboratory findings, chest computed tomography (CT) results evaluating by CT score on admission, and clinical outcomes were collected and compared. The logistic regression was used to assess the independent relationship between the baseline level of four indicators (NLR, LDH, D-dimer, CT score) on admission and the severity of COVID-19, respectively.Results: Among 432 patients, 125 (28.94%) cases were divided into severe group, the remaining (n = 307, 71.06%) were in non-severe group. In multivariate logistic regression, the high level of NLR, LDH were independent predictor in the early classification of patients with COVID-19 (OR = 2.163; 95%CI = 1.162–4.026; p = 0.015 for NLR > 3.82; OR = 2.298; 95%CI = 1.327–3.979; p = 0.003 for LDH > 246U/L). Furthermore, combining NLR > 3.82 and LDH > 246U/L could increase the sensitivity of diagnosis in severe patients (NLR > 3.82 [50.40%] vs. Combined diagnosis [72.80%]; p = 0.0007; LDH > 246 [59.2%] vs. Combined diagnosis [72.80%]; p < 0.0001).Conclusions: The high levels of NLR and LDH in serum have potential value in the early identification of severe patients with COVID-19. The combination of LDH and NLR can improve the sensitivity of diagnosis.Importance: COVID-19 has been a global pandemic. The mortality rate is range from 3.5-6.0%. In order to predict the risk factors of severity of COVID-19. we explore the significance of neutrophil-to-lymphocyte ratio (NLR), lactate dehydrogenase (LDH), D-dimer and CT score in evaluating the severity and prognosis of coronavirus disease – 2019 (COVID-19) in two centers of Hubei, China. We found that the high levels of NLR and LDH in serum have potential value in the early identification of severe patients with COVID-19. The combination of LDH and NLR can improve the sensitivity of diagnosis.

“…Huang and colleagues showed D-dimer levels on admission were higher in patients needing critical care support than those who did not require it [9]. Similarly, Fu and colleagues retrospectively analyzed 75 con rmed COVID-19 adult patients in Suzhou and found that D-dimer levels of the severe group was higher than the mild/moderate on days 1, 4 and 14 [7]. Guan and colleagues analyzed 1099 patients with laboratory-con rmed Covid-19 from over 550 hospitals in China, and found the non-survivors had a signi cantly higher D-dimer than that of survivors [10].…”

Background: The aim of this study was to explore the predictive value of D-dimer and D-dimer to platelet ratio (DPR) on admission in COVID-19 patients. Methods: This is a retrospective cohort study of confirmed COVID-19 patients that were admitted to the Renmin Hospital of Wuhan University from January 30, 2020 to February 15, 2020. The baseline clinical and laboratory parameters were collected.Results: 264 COVID-19 patients were enrolled in this study, of whom 52 died during hospitalization and 212 were discharged from the hospital. Receiver operating characteristic (ROC) curve analysis demonstrated that the area under curve (AUC) of D-dimer was 0.818 with a sensitivity of 75.0% and a specificity of 78.3%, and the AUC of DPR was 0.847 with a sensitivity of 84.6% and a specificity of 75.5% for the prediction of in-hospital mortality on admission. Patients with higher D-dimer or DPR levels were associated with higher mortality risk, compared to those who lower levels. The multivariable Cox regression indicated that in-hospital mortality was associated with age (hazard ratio (HR) 1.034, 95% confidence interval (CI) 1.011-1.058, P=0.003), gender (HR 0.553, 95% CI 0.313-0.976; P=0.041), coronary heart disease (HR 2.315, 95% CI 1.276-4.200; P=0.006), elevated D-dimer (HR 6.111, 95% CI 3.095-12.068; P<0.001), and elevated DPR (HR 7.158, 95% CI 3.633-14.101; P<0.001). Conclusions: DPR levels seem to be slightly better at predicting mortality than D-dimer, and elevated D-dimer and DPR can both be considered independent risk factors of the death in COVID-19 patients.
