Abstract:
Epstein-Barr virus (EBV) infection is the causative agent of multiple diseases. EBV DNA in blood is a useful diagnostic marker of primary EBV infection and reactivation. This study aimed to provide epidemiological information on children with EBV-associated diseases identified by positive EBV DNA in Hangzhou, a city in East China. All children admitted to the Children's Hospital of Zhejiang University School of Medicine from 2010 to 2015 with suspected EBV-related diseases and serum EBV DNA tested by quantitative real-time polymerase chain reaction were included. Of the 10 470 children, 1205 were determined to have positive EBV DNA, and the positive rate was 11.5%. 15.8% (973 of 6162) of the illnesses of patients aged 1 to 7 years were caused by EBV as compared to that of 6.6% (179 of 2708) of children older than 7 years (P < .01) and 3.3% (53 of 1600) of of that of infants <1 year of age (P < .01). Among positive EBV DNA patients, 80.7% of EBV infections occurred in children at the age stage of 1 to 7 years. IM was the most common EBV-related disease, accounting for 75.7% of 581 hospitalized patients. Children aged 1 to 3 years were the age group most commonly hospitalized with EBV-IM (32.7% of the cohort) and EBV-hemophagocytic lymphohistiocytosis (HLH) (52.6%), while EBV-lymphoma was more common in children over 9-year old (58.3% of the cohort). The serum EBV-DNA load was much higher in patients with EBV-HLH than in patients with IM (P < .05). This is a large sample study, which revealed the epidemiological characteristics of children with EBV-associated diseases, including age, monthly and disease distribution.
