Objective We evaluated the long‐term safety and efficacy of injectable poly‐L‐lactic acid (PLLA) for the correction of facial lipoatrophy. Methods This was a randomized, open‐label, comparative, single‐centre study of injected PLLA in patients with HIV‐related facial lipoatrophy. Thirty subjects were randomized to immediate or delayed PLLA treatments, administered as three sets of bilateral injections, 2 weeks apart, into the deep dermis above the buccal fat pad. Week 24 results have been published previously (Moyle et al , HIV Medicine 2004, Vol. 5, pp. 82–87). Long‐term efficacy was assessed at a recall visit using visual analogue scales (VASs) to record patient satisfaction, and by the Hospital Anxiety and Depression Scale (HADS). Patients also reported any adverse events (AEs) during the treatment period and at the recall visit. Results Twenty‐seven patients returned for the recall visit, a minimum of 18 months post final study treatment. Fourteen of these patients were excluded from the recall visit because of additional treatment with PLLA. Improvements in VAS scores for facial appearance were sustained from baseline to the recall visit in both randomization groups ( P <0.05 and P <0.001). Trends in improvement in HADS scores were also noted, with patients in the delayed group experiencing significant improvements in depressive symptoms ( P <0.05). One case of injection‐site induration and nine cases of injection‐site nodules were noted at the recall visit, none of which was described as serious or severe. Conclusions Physical and psychological benefits of PLLA are sustained over at least 18 months. Delayed AEs include mild nodularity at the treatment site.
