Summary
This study highlights a rare case of seronegative systemic lupus erythematosus (SLE) in a patient also diagnosed with autoimmune thyroiditis. It underscores the importance of considering SLE even without positive antinuclear antibodies (ANA) when autoimmune thyroiditis is present.
Area of Science:
- Rheumatology
- Endocrinology
- Immunology
Background:
- Systemic lupus erythematosus (SLE) and autoimmune thyroiditis are both immune-mediated conditions.
- The co-occurrence of SLE and autoimmune thyroiditis has been previously documented.
- Antinuclear antibodies (ANA) are common diagnostic markers for SLE.
Observation:
- A case report of a female patient meeting diagnostic criteria for SLE is presented.
- This patient exhibited negative results for antinuclear antibodies (ANA).
- The patient was concurrently diagnosed with autoimmune thyroiditis.
Findings:
- This case demonstrates a presentation of seronegative SLE.
- The findings emphasize the association between autoimmune thyroiditis and seronegative SLE.
- Clinical characteristics of this dual diagnosis are reviewed.
Implications:
- Highlights the diagnostic challenge of seronegative SLE.
- Suggests autoimmune thyroiditis may be associated with ANA-negative SLE presentations.
- Underscores the need for comprehensive evaluation in patients with autoimmune diseases.
