Results were confirmed in a larger sample, showing that IP-10, TNF-α, interferon- α (IFN-α), IFN-γ, and LT-α were significantly higher in patients with pSS (n=120) compared to non-fatigued controls (n=30), with TNF-α and LT-α inversely related to patient-reported levels of fatigue (19). Here, IFNG is linked to peeling skin syndrome.
