Low-frequency ultrasound (US) applied to skin (sonophoresis) has been investigated to enhance the transdermal transport of various drugs. Histamine is usually used in allergy investigations. We aimed to investigate, in a randomized study, the transdermal penetration of histamine with sonophoresis. Ten subjects were included. Their right forearm was divided into three zones, which were randomly assigned a treatment: no US, US(1) (I(1)=2.72 W/cm(2)), US(2) (I(2)=3.50 W/cm(2)). The primary outcome was area of induced papule, which revealed histamine penetration. Secondary outcomes were echographic measurement of papule (skin thickness) and pruritus. Measurements were taken immediately after US application and after 30 min, 2 h and 24 h. Arm zones without US application showed no papules induced by histamine; 9/10 subjects receiving US showed papules. Their mean size increased with increased intensity of US but not significantly. The skin thickness increased with US. Pruritus occurred in 7/10 cases after US and histamine. The adverse events were skin erythema, pain and tinnitus. Though this study included a few number of patients, it confirms that sonophoresis enhances skin penetration of histamine. This technology could be used at therapeutic levels: histamine could be used with sonophoresis as a positive control in allergy testing instead of prick tests, which involve skin disruption with a lancet.
