Urticarial vasculitis and autoimmune thyroid disease: Do we have enough data?

We read the original article, "Urticarial vasculitis and associated disorders," by Hamad et al.1 In this noteworthy article, the investigators stated that several autoantibodies, including antimicrosomal antibodies, might be detected in patients with hypocomplementemic urticarial vasculitis (HUV) and HUV syndrome, 2 variants of urticarial vasculitis (UV). They provided 2 references to support this statement. We searched for these 2 references and deeply explored the medical literature, and we could not find a conclusive source to confirm or deny that microsomal antibodies are present in UV.
