Palpitation in women with silicone breast implants: association with autoantibodies against autonomic nervous system.

Abstract

We explored a possible association between palpitation manifestation in women with silicone breast implants (SBIs) with circulating level of autoantibodies directed against autonomic nervous system (ANS) receptors. The study was conducted in 93 women with SBIs who arrived to our clinic with diverse symptoms thought to be associated with their implants. Titers of 11 various autoantibodies were measured in the sera of women with SBIs who experienced palpitations (Palpitations, n = 47), did not experience palpitations (Non, n = 46), and healthy women (Control, n = 36). A significant reduction in anti-α2-adrenergic receptor (A2AR, P = 0.035), anti-β2-adrenergic receptor (B2AR, P = 0.027), antimuscarinic receptors M1R (P = 0.048), and anti-M2R (P = 0.039) autoantibodies was found in the 'Palpitations' group as compared with the 'Non' group. Anti-B2AR (P = 0.042), anti-M1R (P = 0.017), and anti-M2R (P = 0.0015) autoantibodies were also significantly reduced in 'Palpitations' as compared with the 'Control' group. Our study shows possible association between autoantibodies directed against ANS receptors, with existing complaints of palpitations in women with SBIs.
