OBJECTIVE: To investigate the relationship between gene polymorphism of CYP2E1, CYP1A1, IL-4 and susceptibility of medicamentosa-like dermatitis induced by trichloroethylene (TCE).
METHODS: 35 patients with medicamentosa-like dermatitis induced by TCE were chosen as the patient group, and 35 healthy workers as control group. The real-time quantitative polymerase chain reaction (PCR) with TaqMan minor groove binding (MGB) probes was used to test single nucleotide polymorphisms (SNP) of CYP2E1, CYP1A1 and IL-4 in the patients with medicamentosa-like dermatitis as well as in the control. The genotypes and the frequency of genotype or allele were compared between the patients and control with statistical analysis.
RESULTS: The frequency of allele G within CYP1A1 gene (rs1048943) was significantly higher in TCE patients (37.1%) than that in control (P<0.05); the frequency of allele T within CYP2E1-1053 C/T was significantly higher in TCE patients (41.4%) than that in control (P<0.01); the frequency of T/T within IL-4-588 C/T (rs2243250) was significantly higher in TCE patients (75.0%) than that in control (P<0.01), and the frequency of allele T within IL-4-588 C/T (rs2243250) was also significantly higher in TCE patients (87.5%) than that in control (P<0.01).
CONCLUSION: The gene polymorphism of CYP2E1, CYP1A1, IL-4 is probably associated with hypersensitivity for the TCE patients with medicamentosa-like dermatitis, and could be one of the genetic factors related to the individual susceptibility to TCE exposure.
