Objective: To investigate the clinical characteristics and treatment of benign acute childhood myositis (BACM) associated with influenza A virus. Methods: 52 BACM children hospitalized in Rainbow Hospital of Xianyang City from March 1,2023 to June 1,2023 were selected. Their gender, age, etiology and clinical characteristics were collected, and their epidemiological characteristics were summarized. Blood biochemical results and the length of hospitalization of the children were collected, and the group using hormone was set as the observation group and the group without hormone as the control group to analyze the therapeutic effect of hormones on the children. Results: Fifty-two children, 37 male and 15 female, were included. Groups 4 to 5,5 to 6,6 to 7,7-8, and> 8 years, were 6,9,20,10 and 7, respectively. Clinical features: (1) Fever: a total of 52 cases, including 8 cases with low heat (37.3~38℃), 31 cases with medium (38.1~39℃), 13 cases with high fever (39.1~41℃), and 0 cases with ultra-high heat (> 41℃). (2) Fifty patients presented with calf muscle pain, and two children presented with calf combined with thigh muscle pain. (3) Respiratory symptoms: 45 cases, including 41 cough, 36 with nasal congestion and runny nose, and 1 case of wheezing. (4) Gastrointestinal symptoms: 12 cases, including 9 of vomiting and 5 of diarrhea. No levels of creatine kinase, myoglobin, lactate dehydrogenase, ALT, ALT, leukocytes, RBC cells, hemoglobin, platelets were present in the observation and control groupsSignificant difference (all P≥0.05). Creatine kinase, myoglobin, lactate dehydrogenase and hospital stay in the observation group after treatment were lower than those in the control group (P<0.05). Conclusion: BACM caused by influenza A mainly involves male children, mainly manifested as fever and calf muscle pain. The use of hormones has a significant effect on the decline of creatine kinase, myoglobin and lactate dehydrogenase, and can shorten the hospitalization of children.
