- Description
- Background/Aims: Chronic Obstructive Pulmonary Disease (COPD) is characterized by airway inflammation, in which contributes to loss of lung function. Systemic inflammation is also a feature of COPD contributing to many associated co-morbidities. Statins, omega-3 fatty acids (docosahexanoic acid, DHA and eicosapentanoic acid, EPA) and lycopene have been shown to decrease systemic inflammation; however their combined effects have not been investigated. This study aims to identify changes in systemic and airway inflammation induced by statins alone or in combination with DHA, EPA and lycopene in COPD. Methods: COPD patients (n = 11) received rosuvastatin (20 mg/day) for 4 weeks, then a combination of rosuvastatin (20 mg/day), DHA and EPA (1.5 g/day) and lycopene (45 mg/day) for 8 weeks. Blood and sputum were collected and lung function measured by spirometry at baseline, week 4 and 12. Plasma fatty acids were measured using gas chromatography, while plasma carotenoids were analysed using high-performance liquid chromatography. Plasma CRP and IL-6 concentrations were measured using ELISA; and peripheral blood gene expression was measured using the nCounterTM GX Human Inflammation Kit 2. Results: Following the interventions, clinical characteristics and plasma IL-6 and CRP were unchanged. Sputum neutrophil proportion and absolute count was increased and macrophage proportion decreased by rosuvastatin (P = 0.020 and P = 0.015; respectively). Rosuvastatin increased LTB4R and decreased CXCL10 and AGER gene expression in white blood cells. The addition of lycopene and omega-3 fatty acids decreased LTB4R and increased CXCL10 to basal levels, whilst combined use of interventions increased ALOX15 blood gene expression. Conclusion This study shows that rosuvastatin, omega-3 fatty acids and lycopene have some anti-inflammatory effects systemically, but rosuvastatin may increase airway neutrophils, which would be undesirable in COPD patients, warranting further investigation.
