Abstract:
OBJECTIVE: To explore the potential association between occupational medicamentosa-like dermatitis induced by trichloroethylene( OMDT) and past infection,reactivation and recent infection of human herpesvirus 6( HHV6) and human cytomegalovirus( HCMV). METHODS: Twenty OMDT patients were recruited as case group by using judgment sampling method. Twenty healthy workers occupationally exposed to trichloroethylene for more than half a year were randomly selected as exposure group. Twenty healthy people with no exposure history to trichloroethylene were randomly selected as control group. The enzyme linked immunosorbent assay was used to qualitatively determine the titer of HHV6 and HCMV immunoglobulin( Ig) G,Ig M antibodies from serum samples of these subjects. The polymerase chain reaction was used to qualitatively detect HHV6 and HCMV DNA from whole blood DNA samples of these subjects. The differences of previous infection rate,reactivation rate and recent infection rate of HHV6 and HCMV among these three groups of patients with different clinical types of OMDT were analyzed. RESULTS: The prevalence of HHV6 and HCMV infection in the case group was higher than that in the control group,and the difference was statistically significant( 65. 5% vs 20. 0%,75. 0% vs15. 0%,P < 0. 017). The reactivation rate of HHV6 and HCMV in the case group was higher than that in the control group,but the difference was not statistically significant( P > 0. 017). The recent infection rate of HHV6 and HCMV in the case group was not significantly different from that in the control group( P > 0. 017). There was no significant difference in the past infection rate,reactivation rate and recent infection rate of HHV6 and HCMV between the exposure group and the control group( P > 0. 05),meanwhile in different clinical types of OMDT patients( P > 0. 05). CONCLUSION: OMDT may be associated with past infection of HHV6 and HCMV.
