Although it is now an accepted concept that narrow-band UVB therapy is an efficacious therapy for psoriasis, the relationship between the response rate and the potential effects on serum cytokines is less well-established. The purpose of this study was to investigate the correlation between the response rate and the changes of serum TGF-β and TNF-α necessary for understanding the underlying mechanisms of narrow-band UVB phototherapy. NB-UVB is effective against psoriasis without any obvious side effects and can significantly decrease serum TNF-α and promote TGF-β level of psoriasis patients. Additionally, measurement of TGF-β and TNF-α in serum could be considered as biomarkers of psoriasis activity during NB-UVB therapy.
