Abstract:
Objective To analyze the clinical characteristics of fatal cases with confirmed severe ad﹣enovirus pneumonia in children in order to improve the diagnosis and treatment. Methods The fatal cases of severe adenovirus pneumonia admitted to Pediatric Intensive Care Unit of Hunan Provincial People′s Hospital from January 2019 to July 2019 were collected,whose clinical features,diagnosis,treatment,and the causes of death were analyzed retrospectively. Results A total of eight children were enrolled, and the age ranged from 3 months to 3 years old,and five cases were between 6 months to 2 years old. Three cases had underly﹣ing diseases. Adenovirus genotype identification was performed on six patients,and the results showed that all patients were infected with adenovirus type 7. All patients presented persistent high fever,with a peak temper﹣ature between 39. 8℃ to 41. 0℃,which persisted 10 to 37 days. Blood routine test before admission PICU showed that four cases had the decrease in white blood count and hemoglobin concentration,accompanied by﹣increased serum ferritin levels. Seven cases complicated with infection. Four cases had parainfluenza virus type 3 infection. Six cases had bacterial infection,and Gram﹣negative bacilli were predominant. One had fun﹣gal septicemia. Conventional mechanical ventilation were performed in all patients in this group. Four cases in this group died of severe acute respiratory distress syndrome. The other four cases died of disseminated intra﹣vascular coagulation associated with massive gastrointestinal bleeding, pulmonary hemorrhage, heart failure and septic shock combined with multiple organ failure. Conclusion Fatal adenoviruspneumonia mostly app﹣pears in children between 6 months to 2 years old or with underlying diseases. Adenovirus type 7 was the main serotype. The occurrence of reactive hemophagocytic phenomenon should be worsen progression of the disease. Co﹣infection may be an important cause of death.
