3.2 White blood cells related parameters characteristics after HCMV infection in children of different age
To analyze the effect of HCMV infection on white blood cells, we compared the changes of the WBC, L% and LYM in HCMV-infected children and corresponding control group (Table 2). Compared with the corresponding control group the L% and LYM of HCMV-infected children increased significantly in 0d-21d, 22d-6m, 7m-11m, 12m-23m, and 2y-6y groups (P <0.05) (Table 2). The change of WBC is complicated, in the age groups of 22d-6m, 7m-11m and 2y-6y, the WBC of children infected with HCMV is higher than that of their control groups (Table 2). However, there was no significant increase in WBC in groups 0d-21d and 12m-23m compared with the control groups (P <0.05) (Table 2). The results showed that HCMV infection can cause increase lymphocytes in children’s peripheral blood, but not all WBC of HCMV-infected children aged 0d-6y were elevated.
