Concerning interstitial lung disease (ILD), Gono et al. [48] and Yang et al. [49] found that IL-18 was higher in DM-associated ILD (DM-ILD) compared to DM without ILD but no difference was found between RP-ILD compared to non-RP-ILD [23, 51]. The gene discussed is IL18; the disease is dermatomyositis.
