The effects of lutein on respiratory health across the life course: A systematic review.
    Clinical nutrition ESPEN, 2016, Volume: 13

    Lutein, a fat-soluble carotenoid present in green leafy vegetables and eggs, has strong antioxidant properties and could therefore be important for respiratory health.. We systematically reviewed the literature for articles that evaluated associations of lutein (intake, supplements or blood levels) with respiratory outcomes, published in Medline, Embase, Cochrane Central, PubMed, Web of Science and Google Scholar, up to August 2014.. We identified one Randomized Control Trial (RCT), two longitudinal, four prospective and six cross-sectional studies. The individual studies obtained a Quality Score ranging between 3 and 9. Six studies were performed in children, which examined bronchopulmonary dysplasia (BPD), asthma and wheezing. In adults, 7 studies investigated asthma, respiratory function and respiratory mortality. The RCT found a borderline significant effect of lutein/zeaxanthin supplementation in neonates on the risk of BPD (OR 0.43 (95% CI 0.15; 1.17). No association was found between lutein intake or levels and respiratory outcomes in children. A case-control study in adults showed lower lutein levels in asthma cases. Three studies, with a prospective or longitudinal study design, in adults found a small but a significant positive association between lutein intake or levels and respiratory function. No association was found in the other two studies. In relation to respiratory mortality, one longitudinal study showed that higher lutein blood levels were associated with a decreased mortality (HR 0.77 (95% CI 0.60; 0.99), per SD increase in lutein).. The published literature suggests a possible positive association between lutein and respiratory health. However, the literature is scarce and most studies are of observational nature.

Association between dietary carotenoid intakes and the risk of asthma in adults: a cross-sectional study of NHANES, 2007-2012.
    BMJ open, 2022, 06-14, Volume: 12, Issue:6

    To investigate the association between dietary carotenoid intake and asthma using data from a nationally representative sample of US adults.. Cross-section study.. The National Health and Nutrition Examination Survey 2007-2012.. A total of 13 039 participants aged 20-80 years (current asthma n=1784, non-current asthma n=11 255) were included in this study.. Asthma was defined by self-report questionnaires. Weighted logistic regression analyses and the smooth curve fittings were performed to explore the association between total carotenoid intake, dietary carotenoid subgenera, including (α-carotene, β-carotene, β-cryptoxanthin, lutein with zeaxanthin and lycopene) and the risk of asthma.. The ORs with 95% CIs of dietary α-carotene, dietary β-carotene, dietary β-cryptoxanthin, total lutein with zeaxanthin, total lycopene, dietary carotenoid and total carotenoid intake for individuals with current asthma after adjusting the confounders in model 3 were 0.80 (0.67 to 0.95), 0.67 (0.57 to 0.79), 0.68 (0.55 to 0.85), 0.77 (0.61 to 0.98), 0.71 (0.57 to 0.87), 0.75 (0.59 to 0.96) and 0.61 (0.48 to 0.76) in the highest versus lowest quartile, respectively. The smooth curve fittings suggested a non-linear relationship between total carotenoid intake and the risk of current asthma.. Higher intake of a-carotene, β-carotene, β-cryptoxanthin, lycopene, lutein with zeaxanthin and total carotenoid were associated with lower odds of having current asthma in the US adults. This is a cross-sectional study and no causal relationship can be drawn, so caution is needed to interpret the results.

Zeaxanthin attenuates OVA-induced allergic asthma in mice by regulating the p38 MAPK/β-catenin signaling pathway.
    Allergologia et immunopathologia, 2022, Volume: 50, Issue:5

    Asthma is a heterogeneous and complex chronic airway disease with a high incidence rate, characterized by chronic airway inflammation. Although the anti-inflammatory effect of zeaxanthin has been demonstrated in various disease models, its explicit role in allergic asthma remains elusive.. An allergic asthma model was established by ovalbumin (OVA) stimulation in BALB/c nude mice. The pathological examination, collagen deposition and expression of α-smooth muscle actin (α-SMA) in lung tissues were determined by hematoxylin and eosin (H&E), MASSON and immunofluorescence staining, respectively. Besides, the effect of zeaxanthin on inflammation and oxidative stress was assessed by the enzyme-linked immunosorbent assay (ELISA) and spectrophotometry measure. Moreover, the underlying mechanism was analyzed by detecting the expression of phosphorylated p38 (p-p38), p38, β-catenin, p-c-Jun N-terminal kinase (p-JNK) and JNK with western blot assays.. The distinct infiltration of inflammatory cells was observed in the OVA-induced asthma mice model with significantly increased concentrations of immunoglobulin E (IgE), interleukin-4 (IL-4), IL-5, IL-13 and eotaxin (p˂0.001), which were prominently reversed by zeaxanthin treatment (p˂0.001). In addition, zeaxanthin treatment decreased the OVA-induced collagen deposition and α-SMA expression. A similar inhibitory effect of zeaxanthin on the oxidative stress was also observed in the OVA-induced asthma mice model, as evidenced by the prominent decrease of malondialdehyde (MDA) concentration and the remarkable increase of superoxide dismutase (SOD), glutathione S transferase (GST) and Glutathione (GSH) concentrations (p˂0.001). Moreover, zeaxanthin introduction markedly reduced the relative expressions of p-p38/p38, β-catenin and p-JNK/JNK in the OVA-induced asthma mice model (p˂0.001), indicating that zeaxanthin suppressed the p38 mitogen-activated protein kinase (p38 MAPK)/β-catenin signaling pathway in the OVA-induced asthma mice model.. Zeaxanthin attenuated OVA-induced allergic asthma in mice via modulating the p38 MAPK/β-catenin signaling pathway.
