Psychiatric symptoms as features of systemic lupus erythematosus

An enquiry of the Dutch Lupus Patients Society revealed that 49% of the members had experienced psychiatric symptoms before systemic lupus erythematosus (SLE) was diagnosed and 33% had sought professional psychiatric help at that stage. To determine the frequency of SLE on psychiatric admission 2,121 patients were tested for the presence of SLE-specific antinuclear and anti-DNA autoantibodies. The results suggest that SLE is a cause of admission in psychiatric hospitals at the rate of 0.1-0.2% and routine screening of antinuclear and anti-DNA antibodies on admission is not an effective diagnostic approach.
