Summary
Lupus-erythematosus-like syndromes can occur without typical antinuclear antibodies. These cases highlight diagnostic challenges due to diverse autoimmune presentations and drug-induced reactions.
Area of Science:
- Immunology
- Rheumatology
- Internal Medicine
Context:
- Systemic lupus erythematosus (SLE) diagnosis typically relies on antinuclear antibodies (ANA) with specific patterns.
- Atypical presentations of lupus-erythematosus-like syndromes pose diagnostic challenges.
- The increasing use of medications and improved diagnostic capabilities contribute to recognizing diverse autoimmune conditions.
Purpose:
- To report on three patients presenting with lupus-erythematosus-like syndromes lacking characteristic ANA.
- To investigate the immunological profiles and potential etiologies of these atypical cases.
- To discuss the diagnostic complexities arising from overlapping autoimmune diseases and drug-induced syndromes.
Summary:
- Three patients with lupus-erythematosus-like syndromes were identified, none exhibiting the characteristic high-titer peripheral or homogeneous antinuclear antibodies typically seen in SLE.
- One patient presented with a pseudo-LE syndrome featuring high-titer antimitochondrial antibodies.
- Another patient's condition was attributed to a drug-induced lupus-erythematosus-like syndrome.
Impact:
- Highlights the need for broader diagnostic criteria beyond ANA for lupus-erythematosus-like conditions.
- Emphasizes the role of antimitochondrial antibodies and drug-induced reactions in mimicking SLE.
- Underscores the diagnostic difficulties presented by the spectrum of autoimmune diseases and their varied clinical manifestations.
