The natural killer cell activity was studied in 41 children with mild, moderate and severe atopic dermatitis (AD) and in 37 controls. The natural killer cell function of lymphocytes was reduced in atopic children (mean +/- SD 21.92 +/- 6.18% vs. 43.87 +/- 5.80%; p less than 0.0001). This decrease was not related to the IgE serum level. A negative correlation was found between natural killer cell activity and the clinical severity of AD (r = 0.73; p less than 0.001). Natural killer cell function was re-evaluated after 9 months in 27 children during a quiescent phase of AD; it was still low, but to a lesser degree (27.66 +/- 5.42%, in the quiescent phase, vs. 43.87 +/- 5.80, controls; p less than 0.0001). The reduced natural killer cell activity seems related to the disease activity.

UI MeSH Term Description Entries
D007073 Immunoglobulin E An immunoglobulin associated with MAST CELLS. Overexpression has been associated with allergic hypersensitivity (HYPERSENSITIVITY, IMMEDIATE). IgE
D007223 Infant A child between 1 and 23 months of age. Infants
D007694 Killer Cells, Natural Bone marrow-derived lymphocytes that possess cytotoxic properties, classically directed against transformed and virus-infected cells. Unlike T CELLS; and B CELLS; NK CELLS are not antigen specific. The cytotoxicity of natural killer cells is determined by the collective signaling of an array of inhibitory and stimulatory CELL SURFACE RECEPTORS. A subset of T-LYMPHOCYTES referred to as NATURAL KILLER T CELLS shares some of the properties of this cell type.

D003876 Dermatitis, Atopic A chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus. It is manifested by lichenification, excoriation, and crusting, mainly on the flexural surfaces of the elbow and knee. In infants it is known as infantile eczema.
