Abstract Objective: To investigate the clinical features and the prognostic factors of community-acquired pneumonia (CAP) with “the white lung” in the CT scan. Methods: A retrospective analysis were used. Adult patients with CAP who fulfilled “the white lung”in the CT scan from Jan 2011 to Aug 2014 in the First Affiliated Hospital of Wenzhou Medical University were enrolled and detailed data were recorded, receiver operating characteristic (ROC) curve was obtained. Results: 123 patients were enrolled, 68 cases in the death group and 55 cases were survived. The mortality was 55.3%. Fever and dyspnea were most common symptoms. 34 cases detected pathogenic bacteria, the total detection rate of 27.6%. Compared the death group with the survived group: age (62.86±14.58 vs 56.21±13.90) years, PaO2/FiO2 (191.46±125.25 vs 240.37±104.55) mmHg, LDH value (715.40±414.94 vs 552.68±283.95) U/L, D-dimer value (7.02±6.94 vs 3.60±3.50) mg/L PSI scores (116.96± 37.27 vs 89.18±45.73) and CURB-65 scores (1.76±0.91 vs 1.17±1.01) were statistically significant (P<0.05). Logistic regression indicated that PSI score, the level of DD and LDH are independent valuable factors for predicting prognosis. AUCs of PSI+DD+LDH was 0.759, more higher than one factor. The sensitivity of PSI+DD+LDH was 77.1%, specificity was 65.9%. Combination of PSI score and DD and LDH improved the prognosis prediction. Conclusion: PSI score, the level of DD and LDH are independent valuable factors for predicting prognosis. Combination of PSI score and DD and LDH improved the prognosis prediction.
