Our researches, focused on genetic and HIV-related forms of lipodystrophies, aim to better understand the pathophysiology of these diseases and to improve the patients’ care. We use a translational approach, in close relation with a network of referring physicians, by evaluating cellular models as well as DNA, cells and tissues issued from the patients. We study the molecular and cellular pathophysiological mechanisms and the clinical and biological determinants that help diagnosis and/or influence the metabolic and cardiovascular prognosis. We also investigate new therapeutic strategies for the prevention and treatment of lipodystrophies.
The molecular diagnosis of most forms of genetic lipodystrophies is routinely performed under responsability of Olivier Lascols at Saint-Antoine Hospital.
We have created dedicated medical consultations for patient with lipodystrophies, to perform diagnosis, genetic counseling, devoted metabolic investigations and dosages, and adapted metabolic and cardiovascular management and follow-up.
Our center is accredited to propose a compasionate therapy with recombinant leptin (Myalept, Astra-Zeneca) to lipodystrophic patients with metabolic complications and leptin deficiency (authorization by Agence Nationale de Sécurité du Médicament et des Produits de Santé, ANSM).
