Abstract:Objective To investigate the risk factors of poor clinical prognosis in children with human adenovirus type 7 (HAdV-7) pneumonia and to construct the correlative prediction model. Methods A total of 160 children with HAdV-7 pneumonia treated in Liuzhou People’s Hospital of Guangxi Zhuang Autonomous Region from January 2018 to January 2022 were selected. According to the prognosis, they were divided into good prognosis group (130 cases) and poor prognosis group (30 cases). The risk factors of poor prognosis of HAdV-7 pneumonia in children were analyzed, and the risk prediction model was established, the receiver operation characteristic curve was drew to test the prediction effect of the model. Results The duration of fever ≥38.5℃ in poor prognosis group was longer than that in good prognosis group, C-reactive protein (CRP), lactate dehydrogenase (LDH), procalcitonin(PCT), and aspartate aminotransferase(AST) were higher than those in good prognosis group, and the proportion of pleural effusion was higher than that in good prognosis group (P<0.05). CRP (OR=1.314), LDH (OR=1.018), PCT (OR=7.268), AST (OR=1.148), and lactate dehydrogenase (LDH), procalcitonin(PCT), and aspartate aminotransferase(AST) pleural effusion (OR=31.406) were independent risk factors for poor prognosis of children with HAdV-7 pneumonia (P<0.05). The prediction model equation was Y=-43.761+0.273×CRP+0.018×LDH+1.983×PCT+0.138×AST+3.447× pleural effusion. The area under the curve of the model was 0.979 (95%CI: 0.950-1.000), the sensitivity was 93.3%, the specificity was 95.4%, the Yoden index was 0.887, and the cut-off value was 0.360. Conclusion The poor prognosis of children with HAdV-7 is related to CRP, LDH, PCT, AST, and pleural effusion, so the prediction model is constructed and contributed to effectively predict the prognosis of children with HAdV-7 pneumonia.
