The likelihood of digital vascular pits, ulcers, or gangrene is increased in patients with scleroderma who are double-positive for anti-interferon-inducible protein 16 and anticentromere autoantibodies. Particularly high anti-interferon-inducible protein 16 levels were found in patients with scleroderma who had active ischemic ulcers or gangrene. Measuring anti-interferon-inducible protein 16 levels in patients with scleroderma and anticentromere antibody positivity may help stratify those at high risk for significant digital vascular events.
