FARSHCHIAN, Mahmoud; ANSAR, Akram; SOBHAN, Mohammadreza  e  HOSEINPOOR, Valiollah. C-reactive protein serum level in patients with psoriasis before and after treatment with narrow-band ultraviolet B. An. Bras. Dermatol. [online]. 2016, vol.91, n.5, pp.580-583. ISSN 1806-4841.  https://doi.org/10.1590/abd1806-4841.20164655.

Background:

C-reactive protein is an inflammatory biomarker and its level increases in the serum of psoriatic patients. Its level is also associated with Psoriasis Area and Severity Index score.

Objective:

The aim of this study was to assess the decrement of serum C-reactive protein level with narrow-band ultraviolet B (NB-UVB) therapy.

Methods:

C-reactive protein serum levels in psoriasis patients were measured before and after treatment with NB-UVB and the data were analyzed in relation to the Psoriasis Area and Severity Index score improvement.

Results:

Baseline C-reactive protein levels among psoriatic patients were higher than normal. These levels decreased significantly after treatment (P<0.001). At the beginning of the study, patients with higher levels of C-reactive protein also had more extensive and severe skin involvement. The highest decrease in C-reactive protein was observed in patients who responded better to the treatment and achieved a higher Psoriasis Area and Severity Index 75%. There was an association between baseline Psoriasis Area and Severity Index scores and C-reactive protein levels.

Conclusion:

Patients with moderate to severe plaque-type psoriasis had active systemic inflammation, which was demonstrated by increased levels of C-reactive protein. Furthermore, skin disease severity was correlated with C-reactive protein levels. Phototherapy healed the psoriatic skin lesions and reduced inflammation, while decreasing C-reactive protein levels.
