UVB Maintenance Phototherapy in Psoriasis

John W. Petrozzi M.D.*

ABSTRACT: Twenty-six patients with generalized stable plaque-type psoriasis were treated three to five times weekly with midwave fluorescent ultraviolet radiation (UVB) combined with either tar or lubricants. After clearing, patients received maintenance treatment with lubricant and UVB for a minimum of four weekly exposures, which were subsequently decreased in frequency. A shielded control site was observed. During maintenance treatments no prolongation in remissions with UVB maintenance could be demonstrated.
