Susceptibility to contact allergy may be influenced by genetically determined alterations in the production of pro- and anti-inflammatory cytokines. This report focuses on functional polymorphisms in the genes encoding for several cytokines involved in the pathogenesis of contact allergic responses, including tumour necrosis factor (TNF)-α (G-238 A, G-308 A), interleukin (IL)-1β (C-511G, T + 3953C), its natural antagonist, the IL-1 receptor antagonist (VNTR intron 2), and IL-6 (G-174C). Polymorphisms were investigated by PCR techniques among polysensitized individuals, defined as individuals with confirmed contact sensitization to para-substituted aryl compounds and at least one other structurally unrelated allergen (n = 86), and healthy control individuals without a history of eczema (n = 310). The distribution of TNFA-308 genotypes was significantly different in these groups (Padjusted = 0.0378). Compared with carriers of 2 wild-type alleles (TNFA-308*1/1 (*G/G)), carriers of the TNFA-308*1/2 (*G/A) and TNFA-308*2/2 (*A/A) genotypes tended to be more common among polysensitized individuals [OR = 1.54, 95% CI (0.92-2.55) and OR = 2.36 (0.84-6.51), respectively]. No significantly different distribution of genotypes was detected at any other polymorphic loci among control individuals without eczema and polysensitized subjects. These findings suggest a possible relationship between the TNFA-308 polymorphism and contact allergy. The results need to be confirmed in future studies.
