IL10 and peeling skin syndrome: Compared with healthy subjects, the CD19+/CD38hi/CD24hi/IL-10-producing B-cell subpopulation (0.20 ± 0.02% in healthy subjects) was greater in pSS patients with clinically inactive disease (0.63 ± 0.06%), with clinically active disease (0.55 ± 0.05%), with positive serology (0.57 ± 0.07%) and without serologic activity (0.53 ± 0.07%) (P < 0.05) (Table 2; Figure 2A).
