About 40\u201380% of children with infectious mononucleosis have hepatic injury, and hepatic failure is one of the main causes of death in patients with fatal infectious mononucleosis. Identifying the demographics, presenting clinical characteristics and the risk factors of hepatic injury in infectious mononucleosis children are helpful to remind clinicians which patients are prone to have hepatic damage.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Methods:<\/jats:bold>\n                    A descriptive, cross-sectional study with a 31-month retrospective review was performed on all infectious mononucleosis children hospitalized in the pediatric department of Fuyang People's Hospital. Demographic data, presenting features, radiology imaging, clinical and laboratory parameters, and clinical outcomes of infectious mononucleosis children were collected.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    Two-hundred twenty-one infectious mononucleosis inpatients were enrolled, and 43.9% (97\/221) patients were considered to have a hepatic injury (defined as alanine amino transaminase &amp;gt; 40 U\/L). Compared with patients without hepatic injury, hepatic injury patients were marked with a significantly higher percentage of hepatomegaly (31 vs. 49%), splenomegaly (58 vs. 81%) and palpebral edema (47 vs. 63%), higher age (3.05 \u00b1 2.12 vs. 3.84 \u00b1 2.44), hospitalization days (6.85 \u00b1 2.64 vs. 8.08 \u00b1 2.83), leukocyte (14.24 \u00b1 5.32 vs. 18.53 \u00b1 8.63), lymphocytes (9.48 \u00b1 4.49 vs. 13.80 \u00b1 7.47), the proportion of atypical lymphocytes (0.12 \u00b1 0.07 vs. 0.15 \u00b1 0.08) and aspartate aminotransferase (33.71 \u00b1 10.94 vs. 107.82 \u00b1 93.52). The results of correlation analysis and multiple linear regression analysis indicated that age (OR = 1.185; 95% CI = 1.035\u20131.357,\n                    <jats:italic>p<\/jats:italic>\n
