Abstract:
Objective To study on immunity function in infectious mononucleosis (IM) children infected by Epstein-Barr virus (EBV) and its relationship with clinic and prognosis.Methods Serum immunoglobulin was detected by immunoradiometric nephelometry,expressions of C D3+,CD4+,CD8+,CD19+,CD23+ on T-lymphocytes subset in peripheral blood were measured by flow cytometry in 50 IM (IM group)who was in acute and convalescent period,and compared with 50 healthy controls (control group).Results The levels of IgA,IgG,IgM in IM group with acute period were (0.75 ± 0.65),(7.55 ± 2.05),(1.85 ± 0.55)g/L,in IM group with convalescent period were (0.95 ± 0.55),(8.85 ± 2.25),(1.75 ± 0.65) g/L.In control group,those were (1.25 ± 0.75),(10.65 ± 2.55),(1.80 ± 0.50) g/L.IgA and IgG in IM group with acute period were significantly lower than those in IM group with convalescent period and control group (P ＜0.01),but IgM was no significant difference among them (P ＞0.05).The levels of CD3+,CD4+,CD8+,CD4+/CD8+,CD19+,CD23+ in IM group with acute period were 0.6050 ± 0.0850,0.2080 ± 0.0315,0.6520 ± 0.0520,0.45 ± 0.35,0.0580 ± 0.0205,0.0250 ± 0.0135,in IM group with convalescent period were 0.7220 ± 0.0820,0.3575 ± 0.0375,0.3565 ± 0.0565,1.45 ± 0.45,0.1580 ± 0.0280,0.0625 ± 0.0225.In control group,those were 0.7530 ± 0.0830、0.4850 ± 0.0450、0.3275 ± 0.0575 1.48 ± 0.55、0.1850 ± 0.0560、0.0805 ± 0.0175.CD3+,CD4+,CD4+/CD8+,CD19+,CD23+ in IM group with acute period were significantly lower than those in IM group with convalescent period and control group (P ＜ 0.05),but CD8+ was significantly higher than that in IM group with convalescent period and control group (P ＜0.05).Conclusion The abnormality of immunoglobulin and T-lymphocytes subset in children infected by EBV is obvious.
