Facial lipoatrophy is a frequent adverse effect of HIV-infected patients due to antiretroviral therapy. Intradermal injection of polylactic acid (Newfill) is one of the currently available treatments. Newfill is a resorbable implant and follow-up has to be rigorous. The Pharmacy and the Infectious Diseases units at the Saint-Louis hospital implemented a follow-up procedure. A follow-up of treated patients was made for 20 months. 127 patients were included. The rate of traceability was 100%. Such traceability is therefore feasible and will have to be implemented for the follow-up of patients treated with future filling products.
