The BAFF levels were significantly elevated in the 13 JM patients with ILD compared to healthy controls (median 1304 pg/mL IQR 1360 pg/mL vs. 692 pg/mL IQR 481 pg/mL p = 0.0124) and in the 13 JM patients without ILD (median 940 pg/mL IQR 481 pg/mL vs. 692 pg/mL IQR 279 pg/mL p = 0.0061) when compared to controls, as shown in Figure 2. This evidence concerns the gene TNFSF13B and interstitial lung disease.
