Résumé
Une augmentation de la masse grasse, telle qu’observée au cours de l’obésité androïde et du syndrome métabolique, est clairement associée à des complications métaboliques. Cependant, à l’inverse, l’absence ou la perte de tissu adipeux (TA) lié aux lipodystrophies, qu’elles soient d’origine génétique ou acquise, conduisent à des atteintes métaboliques encore plus sévères, associées à des complications précoces. Ces dernières années, l’étiologie génétique d’un certain nombre de syndromes lipodystrophiques a été élucidée [1–9], soulignant ainsi le rôle majeur de plusieurs protéines dans la physiologie du TA. Les syndromes lipodystrophiques acquis, quant à eux, peuvent être d’origine iatrogène, liés à certains traitements, antirétroviraux de l’infection VIH ou aux glucocorticoïdes, ces formes étant assez communes, ou encore associés à des dérèglements endocrines ou immunitaires.
