Objective To explore the clinical characteristics of hospitalized children with influenza A virus pneumonia complicated with other pathogens.Methods The clinical data of 153 children with influenza A virus pneumonia hospitalized in Guangzhou Women and Children Medical Center in the past two years(June 2021～June 2023)were analyzed retrospectively.According to whether they were infected with other pathogens,they were divided into mixed infection group and non-mixed infection group,with 98 cases and 55 cases respectively.The clinical characteristics of the two groups were analyzed and compared.Results Fever,cough,vomiting and diarrhea were the main symptoms in children with influenza A virus pneumonia,and the proportion of vomiting and diarrhea in children with mixed infection group was higher than that in children without mixed infection group(P＜0.05).There was no significant difference in other symptoms and complications between the two groups(P＞0.05).There were 65 children(29.41%)with influenza A virus pneumonia and 33 children(21.57%)with mycoplasma pneumonia,20 children(13.07%)with virus infection.Compared with non-mixed infection group,the level of lactate dehydrogenase in children with mixed infection group was higher,and the proportion of children with white blood cell count＜4×109/L was less(P＜0.05).There was no significant difference in other laboratory indexes(P＞0.05).After antiviral and symptomatic treatment,150 cases(98.04%)were cured and discharged,and 3 cases had serious complications,all of which were accompanied by other pathogens.Compared with non-mixed infection group,children in mixed infection group had longer hospitalization days and higher hospitalization expenses(P＜0.05).There was no significant difference in other prognostic indicators(P＞0.05).Conclusions Children with influenza A virus pneumonia are easily infected with other pathogens,which makes it more difficult to treat the disease.Therefore,we should be vigilant in clinic to prevent mixed infection and take effective diagnosis and treatment measures as soon as possible to improve the early cure rate of the disease.
