Title Home Based Targeted Ultraviolet B Phototherapy - Patient Experience and Clearance Rates.
Home Based Targeted Ultraviolet B Phototherapy has recently been made possible with p ortable
devices tailored for home use. Non targeted home phototherapy with UVB panels and wands have
previously been shown as safe and effective. This is the first report of patients who self treat
psoriasis with targeted devices.
Patients with scalp and stable small plaque psoriasis were prescribed a home use device with a
touch screen graphical interface, spot attachment and a fiber-optic brush for treatment of the
scalp. The protocol was programmed in the device according to patient skin type. This consisted
of: starting dose, interval between sessions, rate of increase per session and total sessions. An
on-screen interview prior to each session determined dose increase, decrease or no change from
the previous session.
Clearance data of 20 patients were evaluated. Minimal residual activity was documented with
questionnaires, evaluation by the physician and comparison of before and after pictures. Patients
cleared with an average of 14 sessions (range 10 to 20). Itching and burning sensations
diminished within 6 sessions. Spreading of the light over the affected areas with circular
movement of the brush or tiling spots was even and neither burns, nor were other adverse effects
reported. Patients occasionally skipped treatments. The tracking program of the device lowered
the dose taking into account the loss of built up photoprotecti on to prevent burning.
Home based targeted UVB phototherapy using a device with a smart user interface and an
adapting algorithm has been shown safe and effective, with good patient compliance. Clearance
rates were similar to office based phototherapy. Scalp psoriasis (frequently resistant to
phototherapy) cleared using a fiber-optic brush where the bristles bypassed the hair barrier and
delivered light directly on the scalp.
