Fulminant diffuse systemic sclerosis following aortic valve replacement

Area of Science:

• Rheumatology and Cardiology
• Immunology and Biomaterials Science

Background:

• Diffuse systemic sclerosis (dSSc) is a severe autoimmune condition characterized by widespread skin thickening and internal organ involvement.
• Aortic valve replacement is a common cardiac surgical procedure, often utilizing artificial materials.
• The potential link between foreign materials and autoimmune disease onset or exacerbation remains an area of investigation.

Observation:

• A 61-year-old male presented with symptoms of diarrhea, weight loss, myalgia, and arthralgia following aortic valve replacement for bicuspid aortic valve stenosis.
• The patient rapidly developed fulminant diffuse systemic sclerosis (dSSc) post-surgery.
• Congestive heart failure, attributed to myocardial fibrosis, was identified as the cause of death within six months of symptom onset.

Findings:

• The case highlights a rapid and severe progression of diffuse systemic sclerosis (dSSc) post-cardiac surgery.
• Myocardial fibrosis leading to heart failure was the direct cause of mortality.
• The temporal association suggests a potential role for artificial materials in the disease's pathogenesis.

Implications:

• This case raises a hypothesis that artificial materials (e.g., mechanical heart valves, silicone implants) may induce a fulminant course in pre-existing systemic sclerosis or trigger new-onset disease in predisposed individuals.
• Further research is warranted to explore the immunogenicity of biomaterials and their potential role in systemic sclerosis development.
• Clinicians should consider potential triggers for autoimmune diseases in patients presenting with relevant symptoms after exposure to foreign materials.
