OBJECTIVE The aim of this study was to retrospectively analyze clinical characteristics and laboratory results of the novel coronavirus pneumonia (COVID-19) patients so as to identify factors related to disease progression. PATIENTS AND METHODS Sixty-one patients with COVID-19 were divided into two groups: an improvement/stabilization group (n = 53) and a progression group (n = 8). Clinical data were collected to analyze and compare the differences between the two groups. RESULTS Of the sixty-one patients, thirty-one were male (50.8%), and thirty were female (49.2%), with a median age of 53 years. On admission, significant differences were observed between the two groups with respect to the levels of Creatine Kinase (CK), lymphocytes, D-dimer and creatinine, and prothrombin time (PT). Univariate logistic regression analysis showed that Platelet-to-lymphocyte ratio (PLR), lymphocytes, Mean platelet volume to lymphocyte ratio (MPVLR), CK, White Blood count to mean platelet volume ratio (WMR), Lymphocyte-to-monocyte ratio (LMR), and serum creatinine were important factors for disease progression. Multivariate logistic regression analysis showed that PLR was an independent factor for disease progression in COVID-19 patients. The receiver operating characteristic (ROC) curve revealed that the best predictor of disease progression was CK. Dynamic changes in the laboratory indicators of patients were tracked, and significant differences were found in the variation trends of white blood cell count, neutrophil count, and WMR, which gradually increased in the progression group, but gradually decreased in the improvement/stabilization group. CONCLUSIONS Risk factors for disease progression included PLR, lymphocytes, MPVLR, CK, WMR, LMR, and creatinine, among which, PLR is an independent risk factor for disease progression in COVID-19 patients.
