Abstract:
Objective:To learn about the epidemiological and clinical characteristics of children with brucellosis, in order to provide reference for clinical diagnosis and treatment of brucellosis in children.Methods:Clinical data of children with brucellosis (aged ≤14 years) who visited the Department of Infectious Diseases at Beidahuang Industry Group General Hospital from December 2020 to December 2022 were retrospectively collected, and their epidemiological characteristics, clinical characteristics, laboratory tests, treatment and outcome were summarized and analyzed.Results:A total of 34 children with brucellosis were included, including 25 males (73.53%) and 9 females (26.47%), with a gender ratio of 2.78 ∶ 1.00. The median age was 8 years and 1 month, mainly in the age group of 6 to 14 years (19 cases, 55.88%). Epidemiological investigation showed that most of the affected children were rural residents (25 cases, 73.53%), with more contact with cattle/sheep (26 cases, 76.47%). The onset time was mainly concentrated in summer (15 cases, 44.12%) and spring (13 cases, 38.24%). The clinical symptoms were mainly fever (97.06%, 33/34) and arthralgia (64.71%, 22/34). In the laboratory tests, 25 cases (73.53%) had positive blood cultures, and the white blood cell count (WBC) of 30 cases (88.24%) was (4 - 10) × 10 9/L. Among the abnormalities of liver function, aspartate aminotransferase (AST) increased in 19 cases (55.88%), alanine aminotransferase (ALT) increased in 14 cases (41.18%) and γ-glutamyl transpeptidase (GGT) increased in 6 cases (17.65%). Among the myocardial enzymatic abnormalities, α-hydroxybutyrate dehydrogenase (HBDH) increased in 29 cases (85.29%), lactate dehydrogenase (LDH) increased in 27 cases (79.41%), and creatine kinase isoenzyme (CK-MB) increased in 8 cases (23.53%). After treatment, 25 children with positive blood culture turned negative. Conclusions:Children with brucellosis are mainly male, older and rural residents. The clinical manifestations are mainly fever and arthralgia. Doctors in relevant departments should conduct detailed epidemiological investigations and laboratory tests for such children in clinical work, in order to achieve early detection, diagnosis and treatment of pediatric brucellosis.
