Abstract:
Objective:To study the clinical characteristics of children with adenovirus pneumonia complicated with liver injury and the understanding of clinicians.Methods:The children diagnosed with community-acquired adenovirus pneumonia were enrolled from January 1, 2013 to December 31, 2020. The clinical characteristics of the normal liver function group and the liver injured group were compared, and multivariate regression was applied.Results:Among the 3 294 enrolled children, 1 704 children had elevated alanine aminotransferase and/or aspartate aminotransferase on admission, and the liver function impairment rate was 51.7% (1 704/3 294), of which 1 671 cases were mildly injured (98.06%, 1 671/1 704), 28 cases were moderately injured (1.64%, 28/1 704), and 5 cases were severely injured (0.29%, 5/1 704). Compared with the normal liver function group, the proportion of male children in the liver injured group was higher (68.1% vs. 64.2%, P=0.017), and the age was younger[16(9, 30) months vs. 38(19, 53) months, P<0.001]. Children with liver injury were more likely to have wheezing (32.9% vs. 18.7%, P<0.001), shortness of breath (13.7% vs. 9.1%, P<0.001), and diarrhea (11.0% vs. 4.7%, P<0.001). The white blood cell counts, neutrophil counts and hemoglobin in the liver injured group were lower than those in the normal group, while the lymphocyte counts were higher than those in the normal group. The levels of creatine kinase, cardiac creatine kinase and lactate dehydrogenase were higher. The proportion of severe pneumonia in the liver injured group (26.9% vs. 11.2%, P<0.001) was higher than that in the normal liver function group, and the case fatality rate was significantly higher (1.47% vs. 0.25%, P<0.001). Comparing the probability of liver injury in children with mild and severe adenovirus pneumonia, it was found that the severe pneumonia group had more frequent liver injury (73.0% vs 46.6%, P<0.001), and both moderate and severe liver injury groups were higher than in the mild group. Further multivariate logistic regression analysis did not find a significant factor associated with the incidence of liver injury. Conclusions:The incidence of adenovirus pneumonia in children with liver injury was high, and mild injury is more common. Children with liver injury were younger, had more severe clinical symptoms such as wheezing and shortness of breath, and higher proportion of severe pneumonia and mortality. Among them, children with severe pneumonia had a higher proportion of liver injury, and moderate to severe injury was more common. The monitoring of children with different degrees of liver injury should be strengthened.
