Persistencia de la Dermatitis Atópica / Eczema Atopico en la vida adulta depende de varios factores.

Only three studies had data on persistence relative to severity, and these indicated that there was greater risk for persistence with more severe disease at diagnosis.  Six studies considered, and found no relation between persistence of AD and sensitivity to allergens, as reflected in skin-prick testing and/or antigen-specific IgE.
 
Silverberg and colleagues note that while they found disease severity, older age of onset, and female gender as risk factors for persistent AD, they also determined that 80 percent of childhood AD did not persist beyond 8 years, and less than 5 percent persisted 20 years after diagnosis.
