Abstract
Toxic oil syndrome (TOS) was an epidemic which broke our in Spain in 1981, caused by the ingestion of rapeseed oil denatured with 2%, aniline and sold illegally as edible oil. More than 20,000 people were affected and mortali ty rate was 8.4%. Genetic susceptibility appears to be involved in the path ology of this disease. Several reports have described association between t he chronic stage of the disease and DR DQ antigens (DR3, DR4, DR2 and DQ8). In the present work, we have reassessed the HLA class II antigens in a wel l-designed case-control study. Triplets uf subjects (n=265) compound by chr onic patients (n=117), non-affected family members (n=71) and non-related c ontrols (n=77) were studied. Also, HLA class II antigens were analyzed in p atients who had died from TOS (n = 34) and in TOS control patients who died from other non-TOS related causes (n = 13). Regarding surviving patients n o significant association was found between HLA and disease. In contrast, a n increase in phenotypic frequency of DR2 antigen, was found in patients wh o had died from TOS (73.5%) compared with the whole study group: TOS-affect ed alive patients (25.6%, corrected P<0.001), non-affected family members ( 28.5%, corrected P<0.001), non-related controls (23.9%, corrected P<0.001) and dead controls (38.4%, P=0.03).
