Author(s): Clara Balzer, Alexander Hapfelmeier, Alexander Zink, Tilo Biedermann and Bernadette Eberlein*
The association with the intake of thiazide medication and an increased photosensitivity was investigated by testing
15 patients on thiazide medication and 15 controls with stepwise UVA-, UVB- and UVB 311 nm-irradiation.
Erythema and blood flow 24 h after irradiation were quantified by visual assessment (MED) and objective methods
(Dermacatch, Minolta Chromameter, laser doppler flowmetry). A higher UVA-photosensitivity in patients taking
thiazides was found by visual assessment. The sensitivity and specifity of the different devices was compared; objective
measurement of erythema in all chosen wavelengths generally showed the best results with laser doppler flowmetry
closely followed by colorimetry. Phototherapy in patients on thiazide medication should be carried out with caution
since many factors of pharmacologically increased photosensitivity are still not exp.. View More»
