The Effect of Atopy in the Prevalence of Contact Sensitization: The Experience of a Greek Referral Center

Figure 1

Venn diagrams of AT-negative and AT-positive subpopulations. AT-negative patients were uniquely sensitized by MBT 2% (a). In addition, benzalkonium chloride 0.1%, quinoline mix 6%, and mercapto mix 2% sensitized commonly the AT-negative females, AT-negative males, and AT-positive females, while MBT 2% was common to AT-negative females and AT-negative males (b). Further on, MBT 2% uniquely sensitized AT-negative WhC, while AT-negative BlC, AT-negative WhC, and AT-positive WhC were commonly sensitized by benzalkonium chloride 0.1%, primin 0.01%, and black rubber mix 0.1% (c). The next comparison revealed that AT-negative BlC females, AT-negative WhC females, and AT-negative WhC males were commonly sensitized by primin 0.01%, quinoline mix 6%, and paratertiary butylphenol 1%. At the same time, AT-negative BlC females, AT-negative WhC females, and AT-negative BlC males were commonly sensitized by benzocaine 5% and mercapto mix 2%. Finally, AT-negative WhC males were uniquely sensitized by MBT 2% (d). In the case of AT-positive patients with respect to gender and occupation, more common and unique allergens were found. In particular, finally, epoxy resin 1% uniquely sensitized the AT-positive WhC females, AT-positive BlC males, and AT-positive WhC males. Further on, wool alcohols 30% uniquely sensitized AT-positive WhC females and AT-positive BlC males, while benzalkonium chloride 0.1% uniquely sensitized the AT-positive WhC males. In addition, AT-positive BlC females, AT-positive WhC females, and AT-positive BlC males were commonly sensitized by mercury 0.05% and 5-chloro-2-methyl-4-itz-3. Similarly, AT-positive WhC females and AT-positive WhC males were commonly sensitized by primin 0.01% and black rubber mix 0.1%. AT-positive BlC females and AT-positive WhC females were commonly sensitized by quinoline mix 6% and mercapto mix 2%. Finally, AT-positive BlC females, AT-positive WhC females, and AT-positive WhC males were commonly sensitized by quaternium-15 1%, paraben mix 15%, neomycin sulphate 20%, paratertiary butylphenol 1%, and colophony 20% (e). AT: atopy, WhC: white collars, BlC: blue collars, I1: AT-negative males, I2: AT-negative females, I3: AT-positive males, I4: AT-positive females. II1: AT-negative white collars, II2: AT-negative blue collars, II3: AT-positive white collars, II4: AT-positive blue collars. III1: AT-negative white-collar males, III2: AT-negative white-collar females, III3: AT-negative blue-collar males, III4: AT-negative blue-collars females. IV1: AT-positive white-collar males, IV2: AT-positive white-collar females, IV3: AT-positive blue-collar males, and IV4: AT-positive blue-collar females.
