The presence of ILD on high-resolution computed tomography (HRCT) scans as well as a previous or current history of digital ulcers (DUs) were not associated with a differential cytokine profile, apart from IL-6 reaching a borderline statistical significance for higher induced levels in patients with DUs upon stimulation with heat-killed Candida albicans (p = 0.055) (Figure 3a). The gene discussed is IL6; the disease is interstitial lung disease.
