Nucleosomes are complexes that are formed during apoptosis. Psoriasis is a chronic skin disease characterized by keratinocyte hyperproliferation and anti-apoptotic features.
Presented study was focused to expression of circulating biomarkers of cell death (circulating nucleosomes, CN) during Goeckerman therapy of psoriasis (UV, PAHs). We found slightly (but statistically significant) elevated level of circulating biomarkers of cell death (nucleosomes) in patients with plaque psoriasis treated with GR (PAHs, UV radiation).
We suppose that elevated level of CN is a result of combination of the positive effects of GR and its weak genotoxic effect (mainly PAHs). Conclusions are supported by significant correlation between CN and urinary level of 1-OHP after GR and significantly elevated level of CA after GR.
