Identical twins developed systemic lupus erythematosus (SLE), despite shared genetics and environment. Monitoring one twin allowed early diagnosis and successful treatment of the other, highlighting the importance of vigilant follow-up.
Area of Science:
- Immunology
- Genetics
- Rheumatology
Background:
- Systemic lupus erythematosus (SLE) is a complex autoimmune disease.
- Identical twins share nearly identical genetic material.
- Environmental factors are thought to play a role in SLE development.
Purpose of the Study:
- To report a case of identical twins diagnosed with SLE.
- To investigate potential differences in autoantibody profiles and disease manifestations between genetically identical individuals.
- To emphasize the value of early detection through close monitoring.
Main Methods:
- Case study of monozygotic twins.
- Serological testing for autoantibodies (anti-dsDNA, LE test, rheumatoid factor, anti-Scl 70, anti-SSA, anti-ribosomal P).
- Clinical observation and periodic follow-up.
Main Results:
- Both twins presented with high anti-dsDNA antibody titers.
- Only one twin exhibited lupus psychosis and a broader autoantibody profile.
- Early diagnosis and treatment in the second twin prevented disease progression.
Conclusions:
- Genetic identity does not guarantee identical SLE manifestation or autoantibody profiles.
- Environmental factors may influence disease expression.
- Proactive monitoring of at-risk individuals, such as a twin of an SLE patient, is crucial for early diagnosis and management.
