BACKGROUND: studies have suggested that patients with systemic lupus erythematosus (SLE) have increased risk of developing abnormal results in Pap smears, when compared to the general population. OBJECT: to check the prevalence of abnormal Pap smears in patients with SLE compared to the general population relating it with disease duration, use of immunosuppressive and antimalarial agents and autoantibody profile. METHOD: we studied Pap smears of 76 patients with SLE and 80 healthy controls. In patients with SLE we assessed disease duration, use of cyclophosphamide, methotrexate, azathioprine, antimalarials and the presence of anti-RO, anti-LA and anti-DNA. RESULT: the prevalence of abnormal Pap smears was higher in the SLE group than controls (9.4% versus 1.2%, p = 0.03). No relationship was found between abnormal Pap smears and cyclophosphamide (p = 1.0), methotrexate (p = 0.58), azathioprine (p = 1.0) or antimalarial use (p = 0.051), disease duration (p = 0.85), neither with any of the studied auto antibodies. CONCLUSION: there is a higher prevalence of abnormal Pap smears in the studied SLE population than in normal people that is independent of the duration of the disease, use of immunosupressive medication or presence of autoantibodies.
