Increased incidence of anti-dsDNA autoantibody concentration in sera of workers occupationally exposed to diisocyanates.
Sera of 87 industrial workers with a history of occupational exposition to various diisocyanates, toluene diisocyanate, hexamethylene diisocyanate and methylene-diphenyl diisocyanate were analyzed for antibodies to isocyanate-conjugated human serum albumin and for anti-dsDNA autoantibodies. Ten workers (approx. 11%) were shown to have elevated anti-dsDNA autoantibody concentrations and 13 revealed antibodies to isocyanate-modified human serum albumin. The overlap of both tests being positive was calculated at about 40%. It would seem, therefore, that routine estimation of anti-dsDNA autoantibodies could provide additional useful information for the clinical diagnosis of occupational health impairment due to isocyanate exposure.
