Use of phospholipids esterified by omega-3 polyunsaturated fatty acids DHA as a drug in the treatment of psoriasis

Abstract

The present invention relates to the use of a phospholipid esterified with omega-3 DHA polyunsaturated fatty acids or a lipid extract rich in omega-3 DHA in the form of phospholipids for the preparation of a food supplement intended for maintaining normal skin or for the preparation of a pharmaceutical composition useful in the prevention and therapeutic treatment of recent or chronic dermatoses, particularly psoriasis and eczema. Therapeutic compositions comprising a phospholipid esterified with omega-3 DHA polyunsaturated fatty acids or a lipid extract rich in omega-3 DHA in the form of phospholipids are also the subject of the present invention. According to an advantageous feature of the present invention, the phospholipids are esterified with omega-3 polyunsaturated fatty acids, in particular docosahexaenoic acid (DHA).These phospholipids rich in omega-3 DHA can be an animal or plant extract, preferably chosen from fish, shrimp, krill, zooplankton, algae, phytoplankton, or an extract of animal egg, or even a mixture thereof. They can also be obtained by enzymatic synthesis of structured phospholipids rich in DHA.
