Abstract
Background: Dicyclohexylcarbodiimide (DCC) is known to cause occupational allergic contact dermatitis in biotechnology laboratory workers.
Objectives: This study aimed to assess the prevalence of DCC sensitization among workers of one biosynthesis laboratory and to determine the optimal DCC concentration for patch testing.
Materials and methods: 23 laboratory workers frequently exposed to DCC of whom 21 suffered from dermatitis and 11 controls were enrolled into the study. All participants underwent skin patch testing with different concentrations of DCC and other substances used in the work environment. Statistical analysis was conducted to compare results between active and control groups.
Results: Of the 23 workers tested, 56.5% showed positive reactions to DCC. All of them had dermatitis. Morpholine also elicited positive reactions in 26.1% of workers who were all sensitized to DCC. Dimethylformamide and chloroform yielded negative results.
Conclusion: Dicyclohexylcarbodiimide was a major cause of contact dermatitis in the active group indicating an outbreak of contact allergy to DCC in the company necessitating preventive measures. Both DCC 0.1% ac. and DCC 0.05% pet. should both be used for patch testing.
期刊介绍:
Contact Dermatitis is designed primarily as a journal for clinicians who are interested in various aspects of environmental dermatitis. This includes both allergic and irritant (toxic) types of contact dermatitis, occupational (industrial) dermatitis and consumers" dermatitis from such products as cosmetics and toiletries. The journal aims at promoting and maintaining communication among dermatologists, industrial physicians, allergists and clinical immunologists, as well as chemists and research workers involved in industry and the production of consumer goods. Papers are invited on clinical observations, diagnosis and methods of investigation of patients, therapeutic measures, organisation and legislation relating to the control of occupational and consumers".
