ABSTRACT

BACKGROUND:

House dust mites have been reported to play an aportant role in the pathogenesis of atopic dermatitis(AD). In fact a high positive rate for house dust mites in the skin prick test was observed in patients of AD. However, it is quite difficult to determine the clinical relevance of positive immediate hypersensitivity to mite antigen by clarical history alone because AD patients are nearly always exposed to these antigens in their daily lives.

OBJECTIVE:

The aim of this study was to elucidate the clinical. singficance of a positive immediate hypersensitivity reaction by observing the proliferative respons of peripheral blood mononuclear cells(PBMC) to mite antigen in the AD.

METHODS:

The proliferative response of PBMC separated from Dermatopkagoides farinae(Df) positive AD patients to Df antigen was compared with that from Df negative normal controls, Df positive normal controls and Df negative AD patients.

RESULTS:

PBMC from Df positive AD patients showed signinc not proliferation in response to Df antigen evaluated by comparing stimulation indices(SI) among different experiment groups.

CONCLUSION:

Significant correlation between responses of PBMC and immediate hypersensitivity of skin to Df antigen in AD was found, and it was suggested the Df may be a real aggravating factor in the Df positiv AD patients. SI may be used as ar objective criteria to select patients for hyposensitization therapy after doing a skin test.
