With respect to adipokines levels, a significative and negative correlation was found between DII and adiponectin levels, when all the individuals (r = -0.254, p = 0.021) and the control group (r = -0.311, p = 0.040) were considered, but not the drug allergy group (r = -0.225, p = 0.175) (Table 3). This evidence concerns the gene ADIPOQ and drug allergy.
