Systemic sclerosis with anti-RNA polymerase III positivity following silicone breast implant rupture: possible role of B-cell depletion and implant removal in the treatment.
Despite some case reports and small series of women with silicone breast implants (SBI) developing Systemic Sclerosis (SSc), no clear evidence of an association of SBI with SSc is available. However, SSc is characterized by clinical and immunological heterogeneity and autoantibodies are currently the best markers to stratify this heterogeneity of patients. Therefore, we have reviewed the literature for details of autoantibody characterization in reports of SSc associated with SBI. Moreover, the case of an anti-RNA polymerase III-positive SSc with rapid onset and progression, in which SBI rupture was found is described. This case may support a previous observation suggesting a possible role of SBI rupture as a trigger for anti-RNA polymerase III-positive SSc. This possible causal role may be reinforced by the observation that in our patient, despite immunosuppressive treatment, the disease progressed until SBI were removed, and reduction of anti-RNA polymerase III titer was obtained after rituximab treatment. This result may support data suggesting that B-cell depleting therapy may decrease specific autoantibody level in SSc patients, and that these changes are associated with disease improvement.
