On the basis that diagnosis of neuropsychiatric systemic lupus erythematosus (NPSLE) is sometimes difficult and systemic lupus erythematosus (SLE) can present with isolated psychiatric symptoms, we initiated a survey in a psychiatric department to screen for NPSLE in young female inpatients. We prospectively studied consecutive young female patients referred to the department of psychiatry. Antinuclear antibodies (ANA), anti-deoxyribonucleic acid (DNA), and antiextractable soluble nuclear antigens (ENA) in the serum of patients were screened. In case of positive anti-DNA or anti-ENA, the patient was referred to the department of internal medicine. One hundred patients were enrolled, mean age 33.1±8.4 years. Most patients presented underlying psychiatric disorders: depression (46%), schizophrenia (13%), anxiety disorder (6%), and personality disorder (10%). A quarter of the cohort did not display underlying psychiatric disorders before hospitalization. Positive ANA ?1:160 were found in 32 of the 100 patients tested (32%). No patients presented anti-DNA antibodies. One patient had positive anti-sjogrën's syndrome related antigen A (SSA), but did not present any features of SLE or Sjögren syndrome. Thus, systematic screening of SLE is not relevant in young women hospitalized in psychiatric department. However, clinicians should keep in mind that SLE can present with pure psychiatric symptoms.
