Background: inflammatory chemokines such as CCL2 and CCL5 are involved in the progress of osteoarthritis. Crocin with antioxidant and anti-inflammatory properties can reduce the symptoms of osteoarthritis (OA). This study was performed investigate the effect of Krocina™, on the gene expressions and plasma levels of CCL2 and CCL5 in OA patients.
Methods: The study included 35 patients that were randomized in the Krocina™ and placebo groups. The intervention was Krocina™ 15mg daily for four months. Clinical and paraclinical parameters were measured. CCL2 and CCL5 genes expression and plasma levels were determined using the SYBR Green Real-Time RT-PCR and Enzyme-linked Immunosorbent Assay (ELISA) techniques.
Results: The C-reactive protein (CRP) value in the Krocina™ group and the visual analogue scale (VAS) value in the Krocina™ and placebo groups decreased significantly after the intervention. The gene expression of CCL2 in the Krocina™ and placebo groups decreased significantly. On the contrary, the gene expression of CCL5 in the Krocina™ and placebo groups increased significantly. Moreover, the plasma levels of CCL2 in the Krocina™ and placebo groups decreased meaningfully. There was no difference regarding the plasma levels of CCL5 within the Krocina™ and placebo groups before and after the intervention in either of the groups.
Conclusion: Administration of Krocina™ reduced the clinical signs of inflammation and CRP and VAS value. Also, Krocina™ significantly decreased the plasma levels and gene expression of CCL2 in osteoarthritis patients.
