The impact of lifestyle upon the probability of late bacterial infection after soft-tissue filler augmentation

Purpose: Little is known about the influence of lifestyle-related factors upon the risk of late bacterial infection (LBI) emerging at the site of soft-tissue filler augmentation. The aim of this study was to analyze the impact of some such factors on the risk of LBI by comparing their respective prevalence between two groups of previously healthy women: a group in which infection occurred at a site of cross-linked hyaluronic acid (HA) augmentation and a second group which did not have such an infection. Patients and methods: The infection group featured 25 women who developed LBI at a site of cross-linked HA augmentation; the control group featured 92 women who did not experience complications during a 24-month period of observation after the same procedure. Data was analyzed statistically using Chi-square tests and logistic regression. Results: The two groups did not differ significantly in terms of age. However, the frequency of antibiotic therapy, household pet ownership, occupation, hormone replacement therapy or contraception use, and attendance at a swimming pool, sauna, or gym attendance were found to vary with statistical significance, P<0.05. Conclusions: Women in the control group practiced a more active lifestyle. Antibiotic therapy in the year preceding cross-linked HA augmentation was a factor which rendered a patient predisposed towards the development of LBI. Pet ownership was more prominent among women who did not suffer LBI than within the group in which soft tissue filler-related complications had occurred.
