Restorative interventions for HIV facial lipoatrophy.
Facial lipoatrophy is a common and distressing manifestation of HIV lipodystrophy. The changes in facial appearance can reduce quality of life, self esteem and antiretroviral adherence. Apart from the modest benefits of thymidine-based nucleoside analog cessation, there are no proven therapies for lipoatrophy. Management of established fat loss can be challenging as restoration of lost fat mass is extremely gradual. Plastic surgery and cosmetic procedures can restore lost facial volume. Both biodegradable and permanent filling agents have been investigated for HIV facial lipoatrophy. Biodegradable products offer a good safety profile, but maintenance of aesthetic benefits necessitates reinjection over time. Although permanent products offer longevity and lower treatment costs, adverse events should they occur can be serious and of long duration. Despite the substantial increase in options for soft-tissue augmentation in recent years, well-performed clinical studies in HIV-infected adults with facial lipoatrophy are scarce, and long-term clinical safety data are lacking. This review will summarize available efficacy and safety data of the biodegradable and permanent agents utilized for soft-tissue augmentation in this population. Difficulties associated with comparing treatment efficacy data, assessment of facial lipoatrophy presence and severity, and measurement of facial fat will be discussed. Available data indicate that in HIV-infected adults, most filling agents have short-term clinically safety, and can provide aesthetic improvement and improve well-being, social functioning and quality of life. However, well-designed studies with objectively assessed endpoints are needed to elucidate optimal treatments for this distressing condition.
