The MDA5 antibody, also known as an anti-CADM-140 antibody, has especially been associated with CADM [6], and has been used to detect dermatopulmonary syndrome in patients who have undergone allogeneic hematopoietic stem cell transplantation [9] or in patients with DM [10, 11].
What does a positive nxp2 mean?
In DM, anti-NXP-2 autoantibodies are associated with subcutaneous edema, calcinosis, and a severe muscle phenotype characterized by myalgia, proximal and distal weakness, and dysphagia. As anti-NXP-2 positive patients have an increased risk of cancer, we suggest they should undergo comprehensive cancer screening.
