Abstract
AIMS
This report discusses the use of antinuclear antibody (ANA) detection as a screening test for neuropsychiatry systemic lupus erythematosus (NPSLE) in patients presenting a first-episode psychosis.
METHODS
We reviewed the medical records of 85 patients admitted to an emergency service due to first-episode psychosis, during a 1-year period, for whom ANA detection was performed through an IFI HEp2 cell assay. ANA-positive patients were subsequently evaluated for autoantibodies and neuroimaging exams.
RESULTS
Three patients presented as ANA positive in the initial screening and further investigation confirmed NPSLE in two patients. The patients were treated with antipsychotics and cyclophosphamide pulses with satisfactory outcomes.
CONCLUSION
Even though ANA detection is not specific, it is a low-cost procedure and could be an important screening test for NPSLE in the early-onset psychosis.
