Essential Components

Background. Carotenoids and docosahexaenoic acid (DHA) were identified as essential components for eye health and are both naturally present in eggs. Objective. We aimed to evaluate the effect of the daily consumption of two eggs enriched with lutein/zeaxanthin and DHA on macular pigment optical density (MPOD) and on circulating xanthophyll and fatty acid concentrations in healthy participants. Methods. Ninety-nine healthy volunteers consumed either two standard eggs or two enriched eggs per day for 4 months. MPOD was measured at baseline (V0) and at follow-up (V4) using a modified confocal scanning laser ophthalmoscope (primary outcome). Blood samples were collected to determine total plasma and lipoprotein fatty acids and lutein/zeaxanthin compositions at V0 and V4 (secondary outcomes). Results. A slight but significant increase in MPOD was observed for all study participants consuming two eggs per day for 4 months at all eccentricities (0.5°, 1°, 2°, and 4°). Plasma and lipoprotein lutein, zeaxanthin, and DHA concentrations significantly increased in both groups but were greater in the enriched group (for the enriched group (V0 vs. V4): lutein, 167 vs. 369 ng/mL; zeaxanthin, 17.7 vs. 29.2 ng/mL; DHA, 1.89 vs. 2.56% of total fatty acids). Interestingly, lutein from high-density lipoprotein (HDL) was strongly correlated with MPOD at 0.5 and 1° eccentricities (rho = 0.385, p = 0.008, and rho = 0.461, p = 0.001, respectively). Conclusions. MPOD was slightly increased in both groups. Lutein, zeaxanthin, and DHA plasma concentrations were strongly enhanced in the enriched group compared with the standard group. A significant correlation was found between MPOD level and lutein concentration in HDL.

To explore predisease biomarkers, which may help screen for the risk of age-related macular degeneration (AMD) at very early stages, macular pigment optical density (MPOD) and photoreceptor outer segment (PROS) length were analyzed. Thirty late AMD fellow eyes, which are at high risk and represent the predisease condition of AMD, were evaluated and compared with 30 age-matched control eyes without retinal diseases; there was no early AMD involvement in the AMD fellow eyes. MPOD was measured using MPS2® (M.E. Technica Co. Ltd., Tokyo, Japan), and PROS length was measured based on optical coherence tomography images. MPOD levels and PROS length in the AMD fellow eyes were significantly lower and shorter, respectively, than in control eyes. MPOD and PROS length were positively correlated in control eyes (R = 0.386; p = 0.035) but not in AMD fellow eyes. Twenty (67%) AMD fellow eyes met the criteria of MPOD < 0.65 and/or PROS length < 35 μm, while only five (17%) control eyes did. After adjusting for age and sex, AMD fellow eyes more frequently satisfied the definition (p < 0.001; 95% confidence interval, 3.50–60.4; odds ratio, 14.6). The combination of MPOD and PROS length may be a useful biomarker for screening predisease AMD patients, although further studies are required in this regard.

Purpose: The aim of our study was to evaluate the macular pigment optical density in patients with acute and chronic central serous chorioretinopathy and to describe the association between central retinal thickness and choroidal thickness with the macular pigment optical density. Materials and Methods: Eyes with acute central serous chorioretinopathy and chronic central serous chorioretinopathy (patients, who were diagnosed as having disease activity for 6 months) were included in this study. Macular pigment was measured using the heterochromatic flicker technique of the MPS II device for both eyes in patients with acute and chronic central serous chorioretinopathy and in control subjects. Results: Twenty-seven eyes with acute central serous chorioretinopathy, 23 eyes with chronic central serous chorioretinopathy, and 25 control eyes were enrolled. The mean macular pigment optical density in chronic central serous chorioretinopathy (0.480 ± 0.16 density unit (95% confidence interval: 0.390–0.570) was found to be significantly lower than in the control eyes (0.571 ± 0.128 density unit) (95% confidence interval: 0.480–0.670) ( p = 0.007). In correlation analysis, no significant association was detected between the central retinal thickness, choroidal thickness, and macular pigment optical density values in central serous chorioretinopathy group ( p = 0.31, p = 0.71). Conclusion: Macular pigment optical density levels were significantly lower in chronic central serous chorioretinopathy patients than in controls, possibly due to degeneration of the neurosensorial retina, as a result of the long-term persistence of subretinal fluid. There was not a significant correlation between choroidal thickness and macular pigment optical density levels in central serous chorioretinopathy group.

Rationale: Chronic electronic cigarette (EC) users exhibit a higher susceptibility of low-density lipoprotein (LDL) to undergo oxidation as compared to non-user controls. However, there is a paucity of data regarding EC effects on lipid peroxidation in the blood and their relationship to cardiovascular risk. Objective: To test the hypothesis that chronic (≥1 year) EC use exerts intermediate effects on plasma lipid peroxidation and/or antioxidant defense compared to chronic tobacco cigarette (TC) smoking. Methods and Results: We enrolled EC-users (n=32), TC-smokers (n=29) and non-users (n=45), with mean ages of 28.3, 27.8 and 27.4 years, respectively. Plasma concentrations of free polyunsaturated fatty acids and oxidized metabolites were assessed by mass spectrometry. Total antioxidant capacity (TAC), concentrations of glutathione, bilirubin, heme oxygenase-1 (HO-1), and functional activity of paraoxonase1 (PON1) were determined by colorimetric and enzymatic assays. Multivariable analysis was performed using classification models for segregating participants based on biomarker profiles. Plasma arachidonic acid (AA) concentration was higher in TC-smokers but lower in EC-users, together with linoleic acid (LA) concentration, as compared to TC-smokers and non-users (p<0.05). Oxidized LA metabolites (9- and 13-hydroxyoctadecadienoic acid (HODE)) were lower in EC-users and TC-smokers as compared to non-users (p<0.001). Consistently, TAC and bilirubin were elevated in EC-users and TC-smokers as compared to non-users (p<0.05). Of interest, plasma HO-1 concentration was higher in TC-smokers as compared to non-users (p=0.01) with intermediate levels in EC-users. Multivariable analysis identified 5 biomarkers (13-HODE, LA, 9-HODE, 12-hydroxyeicosatetraenoic acid (HETE), AA) that discriminated EC-users from TC-smokers and non-users with an accuracy of 73.4%. Conclusions: Chronic use of EC induces common (i.e. lower 9- and/or 13-HODEs and higher TAC and bilirubin) as well as differential effects (i.e. altered AA and LA concentrations) to those induced by TC, along with intermediate plasma HO-1 concentration, suggesting that EC, likewise TC smoke, could impact cardiovascular risk.
