Defective ADAMTS13 synthesis as a possible consequence of NASH in an obese patient with recurrent thrombotic thrombocytopenic purpura
Thrombotic thrombocytopenic purpura (TTP) is a rare and devastating hematologic disorder frequently associated with multiple organ failure and sometimes death. This syndrome is mainly associated with severe deficiency of ADAMTS13, a disintegrin and metalloprotease with thrombospondin (TSP)‐1 repeats, cleaving high molecular weight von Willebrand Factor (ULVWF) multimers. Decreased plasma ADAMTS13 activity results in the accumulation of ULVWF multimers with consequent platelet activation. Recently, obesity has been considered as a potential independent risk factor for TTP, but the reason of this association is still unknown.
