Abstract

BACKGROUND:

Natural and synthetic rubbers containing rubber accelerators are well-known causes of allergic contact dermatitis (ACD). Latex contact urticaria (CU) has been widely reported, especially when powdered latex glove use was commonplace. Consequently, interventions to reduce latex exposure by altering glove manufacture were introduced.

OBJECTIVE:

This study aimed to analyse trends in UK-reported incidence of occupational skin disease associated with rubber accelerators.

METHOD:

We analysed cases reported to EPIDERM (part of The Health and Occupation Research network) of occupational ACD caused by natural and synthetic rubber products, between 1996 and 2012.

RESULTS:

For the studied period, a decreasing incidence of ACD associated with rubber products was found, with an average annual change of -1.2% [95% confidence interval (CI) -3.1 to 0.7]. The number of cases of latex CU (n = 580) significantly declined. The number of cases of ACD caused by mercapto mix and mercaptobenzothiazole (n = 177) and thiuram mix (n = 603) also declined. Reports of ACD associated with carba mix and its constituents (n = 219) increased significantly, by an average annual percentage of 10.1% (95%CI: 6.1-14.2). Twenty-six cases of ACD caused by rarer rubber compounds were identified, highlighting skin disease attributable to less widely recognized chemicals.

CONCLUSIONS:

These data show a falling reported incidence of occupational ACD attributed to rubber chemicals, but within this a significant rise attributable to the constituents of the carba mix. Clinicians should recognize the changing diversity of chemicals used in rubber manufacturing, and consider including carba mix in their baseline series and testing beyond this in suspect cases to avoid false-negative results.
