RESUMO
Anecdotal reports have linked silicone breast implants to autoimmune diseases, with scleroderma being mentioned most often. In view of other environmental influences--such as silica mining and the toxic oil syndrome--thought to predispose to scleroderma, more systematic immunologic information on women with silicone implants is needed to assess any possible relation to autoimmunity. A cross-sectional survey was carried out with 150 women, of whom 131 had implants. Group 0 consisted of 19 volunteer women without breast implants who felt healthy, group I was 38 volunteer women with breast implants who felt healthy, group II was 82 women with implants who had various symptoms, and group III was 11 women with implants who had autoimmune disease. Scleroderma was overrepresented in group III (6 of 11). Antinuclear antibodies were determined on Hep-2 cells, using serum dilutions of 1:16, 1:64, and 1:256. A positive test was indicated by 1+ or more fluorescence at 1:256. Antinuclear antibody tests were positive in 0% of group 0, 18% of group I (P < .05 versus group 0), 26% of group II, and 64% of group III. There was no correlation between antinuclear antibody positivity and type of implant, indication for implantation, time since first implantation, total number of implants, and report of implant leak or rupture. Women with breast implants may be at risk for the development of antinuclear antibodies. Proof of such an association will require large-scale prospective studies and epidemiologic analyses.
