In this study plasma zinc levels were determined by atomic absorption spectrophotometry in 43 patients with alopecia areata. The results were related to sex, age, duration of the disease, its extent and clinical type, according to Ikeda's classification. As control, zinc plasma levels were determined in 190 healthy subjects. Only one patient could be considered zinc deficient (58 μg/100 ml vs. normal values: 65-125 μg/100 ml). However a trend to lower zinc levels was noted in the remaining patients. The mean plasma zinc level of the alopecic group was 74.2 μg/100 ml versus 95.5 μg/100 ml of the control and more than 70% of our patients had values lower than 77 μg/100 ml (x̄-I SD) compared with 16% in control subjects.
