Summary
This case study highlights a young woman with early sensory-motor polyneuropathy and positive antitopoisomerase I antibodies, who later developed diffuse systemic sclerosis (SSc). It suggests peripheral nervous system involvement may precede SSc diagnosis.
Area of Science:
- Neurology
- Rheumatology
- Immunology
Background:
- Systemic sclerosis (SSc) is a complex autoimmune disease characterized by fibrosis and vascular abnormalities.
- Peripheral nervous system involvement is not a primary recognized feature of early SSc.
- Antitopoisomerase I antibodies are a serological marker associated with SSc, particularly the diffuse subset.
Observation:
- A young female patient presented with sensory-motor polyneuropathy without typical SSc skin or internal manifestations.
- Serological testing revealed positivity for antitopoisomerase I antibodies.
- Four years after initial presentation, the patient developed rapid skin tightening and lung involvement, fulfilling criteria for diffuse SSc.
Findings:
- This case demonstrates peripheral nervous system involvement as a potential early, isolated manifestation of SSc.
- The development of polyneuropathy preceded the characteristic clinical features of systemic sclerosis by several years.
- Antitopoisomerase I antibody positivity was present before the overt SSc diagnosis.
Implications:
- The peripheral nervous system warrants closer attention in the early diagnosis of systemic sclerosis.
- Identifying neurological symptoms may aid in earlier detection and intervention for SSc patients.
- This case underscores the heterogeneous clinical presentation of SSc and the importance of considering non-classical initial symptoms.
