dc.descriptionChemokines may contribute to local and systemic inflammation in patients with psoriasis. Previous studies have demonstrated the importance of chemokine ligands and receptors in the recruitment of T cells into psoriatic lesional skin and synovial fluid. The aim of this study was to evaluate the levels of Th1-related chemokines in psoriasis and to investigate any association with disease severity. We quantified serum levels of CXCL9, CXCL10 and CXCL16 and the frequencies of CD4+CXCR3+ T lymphocytes through ELISA and flow cytometry, respectively. A total of 38 patients with psoriasis and 33 controls were included. There were no significant differences in chemokine levels between psoriasis and control groups. Patients with psoriatic arthritis had lower median level of CXCL10 when compared with controls (p=0.03). There were no significant correlations between serum chemokines analyzed and disease severity. Frequencies of CD4+CXCR3+ T cells were lower in patients with psoriasis than in controls (p<0.01). A sensitivity analysis excluding patients on systemic therapy yielded similar results. Serum concentrations of CXCL9, CXCL10 and CXCL16 were not increased in the psoriasis group or correlated with disease severity. Systemic levels of chemokine ligands do not seem to be sensitive biomarkers of disease activity or accurate parameters to predict response to therapy. Frequencies of CD4+CXCR3+ T cells were decreased in the peripheral blood of psoriasis patients, possibly due to recruitment to inflammatory lesions.
