[Iatrogenic hypertriglyceridemia].

Abstract

Several recent studies have confirmed the pathogenic effect of endogenous hypertriglyceridaemia (type IV) on atherosclerosis and thrombosis. Our understanding of the pathophysiological mechanism involved in these hypertriglyceridaemias is constantly improving. Iatrogenic hypertriglyceridaemia can be caused by several classes of drugs including synthetic oestrogens, especially the oestrogen-progesterone contraceptives, and to a lesser extent natural oestrogens taken orally as replacement treatment during menopause, certain hypotensive drugs (non-cardioselective beta-blockers and thiazidic diuretics), corticosteroids, retinoids, cyclosporine, enzyme inductors and iodine produces (by iodine-induced hypothyroidism). All these situations should be recognized and when high lipid levels are observed treatment protocols should be modified or interrupted. Whether associated with a rise or a fall in cholesterol-LDL, such conditions should always taken into consideration due to the increased risk of atherosclerosis, thrombosis or even acute or subacute pancreatitis.
