Abstract:
Objective To analyze the clinical characteristics of 110 cases of infectious mononucleosis in children. Methods The clinical data of 110 children with infectious mononucleosis in the period from January 2015 to January 2018 were analyzed retrospectively. Results The 110 patients included 74 males(67.3％)and 36 females(32.7％). The male to female ratio was 2.1:1.The age distribution: 2～<3 years old, 29 cases(26.4％); 3-6 years old, 67 cases(60.9％);>6-13 years old, 14 cases(12.7％).The main symptoms and signs included fever in 101 cases(91.8％), pharyngitis in 100 cases(90.9％), lymphadenomegaly in 95 cases(86.4％), eyelid edema in 79 cases(71.8％), splenomegaly in 55 cases(50.0％), and liver enlargement in 37 cases(33.6％).The complications were pneumonia in 61 cases(55.5％), myocardial damage in 53 cases(48.2％), neutropenia in 35 cases(31.8％), and thrombocytopenic purpura in 4 cases(3.6％). The prevalence of IgM antibody against Epstein-Barr virus capsid antigen was43.6％. The prevalence of IgM antibody against Epstein-Barr virus early antigen was 31.8％. The positive rate of IgG antibody against Epstein-Barr virus nuclear antigen was 56.4％. The prevalence of atypical lymphocytes in peripheral blood was 46.4％.Conclusions Infectious mononucleosis in children is more common in males and during the period from 3 to 6 years of age. The clinical symptoms include pneumonia and myocardial damage. Epstein-Barr virus detection and serological assay are helpful for diagnosis.
