Background and Objective.Oxidative stress is intimately associated with many diseases, including chronic obstructive pulmonary disease (COPD). Study objectives include a comparison of the oxidative stress, antioxidant status, and lipid profile between COPD patients and controls and evaluation of the effect of spirulina intervention on oxidative stress, antioxidant status, and lipid profile of COPD patients.Methods.30 patients with COPD and 20 controls with no respiratory problems were selected. Global Initiative for Chronic Obstructive Lung Disease criteria were served as the basis of COPD diagnosis. The serum content of malondialdehyde (MDA), lipid hydroperoxide, glutathione (GSH), vitamin C, cholesterol, triglyceride (TG), and high density lipoprotein (HDL) was measured. The activity of superoxide dismutase (SOD), catalase (CAT), and glutathione-s-transferase (GST) was also measured. Two different doses, (500 × 2) mg and (500 × 4) mg spirulina, were given to two groups, each of which comprises 15 COPD patients.Results.All targeted blood parameters have significant difference(P=0.000)between COPD patients and controls except triglyceride (TG). Spirulina intake for 30 and 60 days at (500 × 2) mg dose has significantly reduced serum content of MDA, lipid hydroperoxide, and cholesterol(P=0.000)while increasing GSH, Vit C level(P=0.000), and the activity of SOD(P=0.000)and GST(P=0.038). At the same time, spirulina intake for 30 and 60 days at (500 × 4) mg dose has favorable significant effect(P=0.000)on all targeted blood parameters except for HDL(P=0.163).

The role of low-density oxidized lipoproteins (OxLDL) in the pathogenesis of occupational chronic obstructive pulmonary disease (COPD) is not understood well enough.The study aims to determine the serum levels of oxidized low-density lipoproteins and their relationship with lipid profile, the level of oxidative stress and level C-reactive protein in patients with occupational chronic obstructive pulmonary disease.Methods. 116 patients diagnosed with occupational COPD and 25 patients with no respiratory diseases (comparison group) were examined. Serum levels of OxLDL was determined by solid phase enzyme-linked immunosorbent assay (ELISA) using the commercial reagent kit MDA-oxLDL from Biomedica Gruppe, Austria.Results. Circulating OxLDL was detected in serum in a significant proportion of patients with stable occupational COPD. In most of the patients, the concentration of OxLDL was within the values observed in the comparison group or exceeded them by no more than two times. In the minority of patients with occupational COPD (16.5%), the concentration of OxLDL was high and 4 – 10 times higher than its average value in the comparison group. It can be assumed that the revealed differences in the concentration of OxLDL are due to the different degree and intensity of oxidation of low-density lipoproteins. The relationships between OxLDL and lipid metabolism, oxidative stress (OS), the antioxidant capacity of serum (AOS), and serum levels of C-reactive protein were described.Conclusion. Serum OxLDL levels in patients with occupational COPD, the relationship between OxLDL and lipid metabolism, oxidative stress, and inflammation will provide an expanded view of the pathogenetic aspects of occupational COPD.
