Experimental trypsin itch was investigated in 100 patients with atopic dermatitis and in 115 controls. The duration or itch exceeded 2 minutes in 62.8% for involved skin and in 37% for uninvolved skin of atopic dermatitis patients, which are significantly higher percentages than in controls. The longer itch duration is not a specific feature of atopic dermatitis, however.
