“… 8 , 9 , 10 D‐penicillamine is one such drug that can induce autoantibody production, including antinuclear antibodies (ANA), anti‐neutrophil cytoplasmic antibodies (ANCA), anti‐muscle‐specific tyrosine kinase antibodies and anti‐acetylcholine receptor antibodies. 11 , 12 , 13 Moreover, multiple liver diseases, including autoimmune hepatitis, influence the immune system and lead to increased serum autoantibody production. 14 Consequently, due to liver injury, as well as D‐penicillamine treatment, we may expect elevated prevalence of autoantibodies in patients with WD.…”
