Evaluation of HA Dermal Fillers in the Treatment of Pathological Facial Lipoatrophy (HAtrophy)

A Prospective and Multicentric Investigation Evaluating the Clinical Safety of FASY F and FASY P Hyaluronic Acid Gel for the Treatment of Pathological Facial Lipoatrophy

Facial lipoatrophy (FLA) refers to the loss of adipose tissue and is manifested by flattening or indentation of convex contours of the face. Most frequently, the subcutaneous layer is affected and most common locations of adipose tissue loss are the cheeks, temples, preauricular, orbital or perioral and oral areas. Most common etiology for FLA is related to HIV. In 1998, first FLA was described in Subjects under highly active antiretroviral therapy (HAART). Currently, no specific treatment for FLA is known. For HIV-associated FLA, the European AIDS Clinical Society (EACS) recommends in prevention, the avoidance of some ART (Active Antiretroviral therapy) such as stavudine and zidovudine. In corrective purpose, the switch of ART is advisable as well as surgical intervention involving dermal fillers.

Different filling treatment options are available to treat volume defect on FLA Subjects including PolyLactic Acid (PLLA) (i.e.; Sculptra®), Calcium hydroxyapatite ( CaHa - i.e.: Radiesse®), autologous fat graft and hyaluronic acid (HA). Several studies shown promising results for the use of HA in this indication with good reconstructive and aesthetic outcomes, excellent safety profile and comparable to the autologous fat transfer treatment. HA fillers are described as voluming agents for treatment of FLA associated with fat wasting disorders, lasting at least 6 months but the persistent volumetric effect depends on HA crosslinking level and concentration.
