Systemic sclerosis and microscopic polyangiitis after systemic exposure to silicone

Area of Science:

• Immunology
• Rheumatology
• Toxicology

Background:

• The association between silicon breast implants (SBIs) and autoimmune/inflammatory syndrome induced by adjuvants (ASIA) remains controversial.
• Previous studies have yielded discordant results, potentially due to inadequate confirmation of systemic silicon exposure.

Observation:

• A 45-year-old woman with confirmed systemic exposure to SBIs presented with a complex autoimmune presentation.
• She developed systemic sclerosis (SSc), a severe autoimmune connective tissue disease.
• Subsequently, she developed anti-neutrophil cytoplasmic antibody (ANCA)-associated anti-myeloperoxidase (MPO) vasculitis with renopulmonary syndrome.

Findings:

• This case provides strong evidence of systemic silicon exposure from SBIs.
• It documents the sequential development of two distinct and severe autoimmune diseases in the same patient.
• The findings highlight the importance of confirming systemic silicon exposure in research.

Implications:

• This case suggests a potential causal link between SBIs and the development of severe autoimmune conditions.
• It underscores the need for rigorous assessment of systemic silicon exposure in future studies investigating SBIs and ASIA.
• Further research is warranted to elucidate the mechanisms by which SBIs may trigger or exacerbate autoimmune diseases.
