Literature review
We did not limit the publication years and conducted a full-text
literature search in the PubMed, Science ISI Web,Embase and Wanfang,
Chinese National Knowledge Infrastructure (CNKI), and Weipu and
databases. Search to identify all studies that may involve the following
keywords: “Epstein-Barr virus infection” or “chronic Epstein-Barr
virus infectious diseases” and “enteritis” or “gastrointestinal
symptoms”. We retrieved documents and perused the reference lists that
were eligible retroactively to avoid missing relevant literature.
A total of 13 English studies and 5 Chinese studies were retrieved.
After a careful review of the full text, 7 studies[7-13] (3 Chinese
and 4 English) and 26 case reports of CAEBV were included in the
statistical analysis.
