Investigation of the lipid-modifying and antiinflammatory effects of Cornus mas L. supplementation on dyslipidemic children and adolescents

Abstract

Cornus mas L. (CM) fruits are rich in anthocyanins and possess both antiinflammatory and antioxidant activities. The current study was conducted to investigate whether supplementation with CM could ameliorate lipid profile and vascular inflammation in dyslipidemic children and adolescents. In this randomized clinical trial, 40 dyslipidemic children and adolescents ages 9 to 16 years were assigned to receive 50 g of CM twice a day after lunch and dinner (n = 20, case group) or to continue their normal diet (n = 20, control group). The serum levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), apo A-I, apo B, intracellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), C-reactive protein (CRP), and anthropometric indices were determined at baseline and then after weeks 3 and 6 of the trial. After week 6 of the trial, the TC, TG, LDL-C, apo B, ICAM-1, and VCAM-1 levels in the CM group were significantly lower and the HDL-C and apo A-I levels higher than at baseline. After week 6 of the trial, none of these parameters in the control group, except for ICAM-1, was significantly altered from baseline. However, between-group comparison showed a significant difference only for apo A-I (p = 0.016) and a borderline significant difference for ICAM-1 (p = 0.076). No significant difference in body mass index, waist-to-hip ratio, or C-reactive protein was observed between the studied groups. The present findings revealed a trend toward amelioration of lipid profile and vascular inflammation following addition of CM to the daily diet of dyslipidemic children and adolescents but this needs to be verified by larger scale trials.
