The minimal erythema dose of narrowband ultraviolet B in elderly Taiwanese

Phototherapy for elderly patients, defined as individuals aged 65 years old or older, has become an emerging issue with aging on the rise. 1 The initial dose of narrowband ultraviolet B (NBUVB, 311nm) phototherapy, a widely utilized treatment modality in Taiwan, is determined by the minimal erythema dose (MED). The reference dose of the NBUVB MED is reckoned from patients from Taiwan whose ages mostly fall between 18 to 60 years old.2 Limited data on the MED of NBUVB for elderly Asian patients were found and no study among elderly Taiwanese patients has been conducted.2-4 Thus, this study aimed to determine the MED of NBUVB among elderly Taiwanese persons. The safety of phototherapy protocol based on yield MED was also evaluated.
