Abstract:
OBJECTIVE:To study the clinical value of lymphocyte subsets, immunoglobulins, and complement C3 and C4 in the evaluation of immune status in children with hand-foot-mouth disease (HFMD).
METHODS:A total of 282 children with HFMD were enrolled as the HFMD group, and 130 healthy children were enrolled as the healthy control group. The percentages of peripheral CD3, CD4, and CD8 T lymphocytes, CD19 B lymphocytes, and CD56 natural killer cells were measured. The CD4/CD8 ratio was calculated. The levels of immunoglobulin A (IgA), immunoglobulin M (IgM), immunoglobulin G (IgG), and complement C3 and C4 were measured.
RESULTS:The multivariate analysis showed that compared with the healthy control group, the HFMD group had significantly lower percentages of CD3, CD4, and CD8 T lymphocytes and levels of complement C3 and C4 (P<0.05), as well as significantly higher percentage of CD56 natural killer cells and level of IgG (P<0.05). The individual effect analysis showed that the children aged 0-3 years in the HFMD group had a significantly higher CD4/CD8 ratio than the healthy control group (P<0.05); boys aged 0-3 and ≥3 years in the HFMD group had a significantly higher level of IgM than the healthy control group (P<0.05); boys aged ≥3 years and girls aged 0-3 years in the HFMD group had a significantly lower level of IgA than the healthy control group (P<0.05).
CONCLUSIONS:Cellular and humoral immunity disorders are observed in children with HFMD. The monitoring of lymphocyte subsets and immunoglobulin levels can provide a laboratory basis for immune status assessment in children with HFMD.
