چکیده (انگلیسی):

Background: Eczema in the cubital fossa, which is susceptible to sweat, is frequently observed in atopic dermatitis
(AD). However, there has been no direct evidence that sweating causes eczema in the cubital fossa.
Methods: To investigate this issue, axon reflex-mediated sweating volume (AXR) and skin barrier function in
the cubital fossa were measured in subjects with AD and in healthy volunteers, and were applied to clinical feature
of the cubital fossa.
Results: AXR in the cubital fossa decreased in AD subjects; it positively correlated only with water-holding capacity
in healthy subjects but not in patients with in AD. Furthermore, AD subjects with lichenoid eczema and
either prurigo or papules over the cubital fossa showed extremely decreased AXR.
Conclusions: These results suggest that decreased sweating is a major source of water in the stratum corneum,
and decreased sudomotor function may be involved in both the cause and aggravation of representative
atopic eczema in the cubital fossa.
