title: [Headache and systemic lupus erythematosus: prevalence and associated conditions].
abstract: OBJECTIVE
  To study the prevalence of headache in patients with systemic lupus erythematosus (SLE) and normal population as well as associated conditions.
  
  
  METHODS
  Forty nine SLE patients and 50 controls were analyzed for presence of headaches (tensional and migraine). In the SLE group, we studied the occurrence of Raynaud, teleangiectasis, cutaneous vasculitis, convulsions and antiphospholipid antibodies.
  
  
  RESULTS
  Among SLE patients, 42 had headaches (85.7%), 29 with migraine and 13 tensional; on the control group, 28 had headaches (57.1%), 18 migraine and 10 tension type with p=0.0026 for migraine. In SLE patients we did not find any association between migraine and Raynaud (p=0.34), teleangiectasis (p=0.77), cutaneous vasculitis (p=0.63), seizures (p=0.13), aCl IgG (p=0.45), IgM (=0.07) and LAC (p=0.59).
  
  
  CONCLUSIONS
  Migraine is more prevalent in the SLE population. However, it has no relationship with Raynaud, teleangiectasis, seizures, cutaneous vasculitis and antiphospholipid antibodies.
