Clinical imaging diagnosis of pulmonary cryptococcosis with different therapeutic responses

We aimed to differentiate and evaluate the clinical imaging features of pulmonary cryptococcosis with different therapeutic responses. The clinical imaging data of 70 patients with PC (complete response PC 37 cases and incomplete response PC 33 cases) were collected and compared to determine the independent risk factors for different therapeutic responses, and their diagnostic performances were verified by receiver operating characteristic curve analysis. Compared with complete response PC, incomplete response PC was more common with immunosuppression (10.8% vs. 45.5%, P = 0.001), intermediate progress (8.1% vs. 39.4%, P = 0.002), bilateral distribution (21.6% vs. 78.8%, P < 0.001), consolidation-interstitial pattern (10.8% vs. 42.4%, P = 0.003), pleural effusion (0 vs. 27.3%, P = 0.002) and mediastinal lymphadenopathy (0 vs. 24.2%, P = 0.005). Multivariate logistic regression showed that immunosuppression, intermediate progress, and bilateral distribution were independent risk factors, with low to moderate areas under curves (AUC, 0.656-0.786). Their combined performance was good with an AUC of 0.888. The diverse clinical imaging features can reflect the therapeutic response of PC. Immunosuppression, intermediate progress, and bilateral distribution were independent risk factors. Their combination can significantly improve diagnostic effects.
