Severe hypertriglyceridaemia in idiopathic (non-HCV-related) mixed cryoglobulinaemia.

We describe a 28‐year‐old male patient in whom the development of idiopathic mixed cryoglobulinaemia (MC) with typical clinical manifestations such as polyarthralgia, weakness, purpura, and Raynaud's phenomenon was associated with a remarkable increase in serum triglycerides (TG). Prednisone administration was effective in classical cryoglobulinaemia symptoms and also in dyslipidaemia. Infective, autoimmune, and haematological disorders are often related to cryoglobulinaemia and it has been analysed that some of them also show an increase in TG.
