[Levels of lymphocyte subsets, immunoglobulins, and complement C3 and C4 in children with hand-foot-mouth disease].

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.
