pSS patients with anti-SSA-antibodies in particular had higher percentages of CCR9+ CD8 T cells compared to HC [median 4.7 (IQR 3.4 – 5.9) for pSS patients and median 1.6 (IQR 1.3 – 3.8) for HC, p=0.03], which was not observed for SSA- patients [median 3.6 (IQR 3.5-3.7)]. This evidence concerns the gene CD8A and peeling skin syndrome.
