title: Trace element levels in alopecia areata.
abstract: BACKGROUND
  Alopecia areata (AA) is a recurrent, nonscarring type of hair loss considered to be an autoimmune process. Though its etiopathology is not fully understood, there are claims that imbalance of trace elements may trigger the onset of AA.
  
  
  OBJECTIVE
  The aim of the present study was to assess the levels of zinc, copper, and magnesium in the serum of AA patients.
  
  
  METHODS
  Fifty AA patients (34 men and 16 women), and fifty age and sex matched healthy control subjects were studied. Samples were analyzed using atomic absorption spectrometric methods.
  
  
  RESULTS
  Serum zinc levels were significantly decreased (P < 0.05) in AA patients whose disease was extensive, prolonged, and resistant to treatment, whereas serum copper and magnesium levels showed insignificant rise compared to controls.
  
  
  CONCLUSIONS
  We conclude that copper and magnesium levels are not altered in AA, but the decreased zinc levels found in our study may merit further investigation of the relationship.
