Clinical characteristics, early blood biochemical indicators, and prognostic status of children with bronchopneumonia.

To investigate the clinical characteristics, early blood biochemical indicators, and prognostic status of children with bronchopneumonia. We conducted a retrospective analysis of data from 500 children diagnosed with bronchopneumonia at our hospital from June 2019 to December 2022. Based on the severity of the disease, patients were assigned to the severe group (n = 180) or mild group (n = 320), and an additional 150 healthy children were chosen as the control group. Blood indicators [aspartate aminotransferase (AST), plasma carbon dioxide combining power (CO2CP), serum potassium (K+), serum sodium (Na+)], inflammatory markers [interleukin-17 (IL-17), interleukin-10 (IL-10), C-reactive protein (CRP), procalcitonin (PCT)], and cardiac enzyme profiles [lactate dehydrogenase (LDH), creatine kinase (CK), alpha-hydroxybutyrate dehydrogenase (α-HBDH), creatine kinase isoenzyme (CK-MB)] were compared among the 3 groups. The severe group showed more signs such as diarrhea, pleural effusion, and respiratory distress than the mild group. AST levels in the severe group were significantly higher than those in the mild group and control group, while CO2CP, K+, and Na+ were lower than those in the mild group and control group. AST levels in the mild group were significantly higher than those in the control group, while CO2CP and Na + were significantly higher than those in the control group (P < .05). IL-10, IL-17, PCT, and CRP levels in the severe group were higher than those in the mild group and control group, while those in the mild group were higher than those in the control group (P < .05). CK, CK-MB, LDH, and α-HBDH levels in the severe group were significantly higher than those in the mild group and control group. CK, CK-MB, LDH, and α-HBDH levels in the mild group were higher than those in the control group (P < .05). The severe group had a longer duration of fever, disappearance of symptoms, and cough relief time than the mild group (P < .05). Children with bronchopneumonia exhibit increased cardiac enzyme (CK, CK-MB, LDH, and α-HBDH) activity, and PCT and CRP expression levels increase with disease severity. Timely detection of relevant blood biochemical indicators and early implementation of prevention and treatment measures can improve the cure rate and reduce mortality in children with bronchopneumonia.
