Abstract
Selenium levels in the Inuit population of Greenland have been declining during the last decades. The association between Selenium and asthma has been investigated previously, but with conflicting results. The objective was to measure human serum Se (s-Se) in Greenlandic seafood processing workers, to compare with levels recorded in previous decades and to establish if s-Se is associated with asthma or lung function. Data, including questionnaire answers, spirometry, skin-prick test and s-Se from 324 seafood processing workers in Greenland were collected during 2016-2017. Mean s-Se values were compared by t-test and one-way ANOVA. Associations between s-Se and asthma, symptoms from the lower airways at work and lung function were assessed using linear regression. The mean s-Se was 96.2 µg/L. S-Se was higher among non-smokers and workers living in settlements. Workers with asthma did not have s-Se levels significantly different from those of non-asthmatics. We found a positive association between s-Se levels and FEV1 values. Selenium levels appear to continue declining in Greenland, presumably because of a more Westernised lifestyle. The health effects of declining Selenium levels remain unclear. We did not establish an association between s-Se and asthma, but we did record a positive association between s-Se and FEV1.

Vitamin C deficiency and risk of metabolic complications among adults with chronic respiratory diseases: A case-control study. Clin Nutr ESPEN 2021; 43:448-455. [PMID: 34024554 DOI: 10.1016/j.clnesp.2021.03.007] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2020] [Revised: 02/12/2021] [Accepted: 03/05/2021] [Indexed: 12/21/2022]
Abstract
BACKGROUND Chronic respiratory disease (CRD) is an airflow limitation that represents a wide array of serious diseases. The aim of this study is to examine the influence of vitamin C deficiency on metabolic health-related quality in individuals with and without chronic respiratory disease in the Gaza Strip. METHODS A matched case-control study including 52 cases of CRD and 52 controls of healthy participants were matched by age, sex, body mass index (BMI) and waist circumferences (WC). The study was conducted at the Ministry of Health secondary health-care centers in Gaza strip, Palestine. The biochemical data included Protein Carbonyl (PC), high sensitivity C reactive protein (CRP), vitamin C, fasting blood glucose (FBG) and markers of the lipid profile. RESULTS By the qualitative estimation of vitamin C consumption, there was a significantly lower consumption of foods that are rich in vitamin C by CRD patients than the matched controls. By comparing the results between both groups, CRD patients had significantly lower plasma concentrations of vitamins C than the control group (18.43 ± 11.93 μgm/ml vs. 24.06 ± 11.19 μgm/ml, P = 0.025), but significantly higher in PC (3.86 ± 4.21 μgm/ml vs. 2.11 ± 0.97 μgm/ml, P = 0.005), CRP (5.98 ± 8.84 mg/l vs. 1.87 ± 1.96 mg/l, P = 0.001), and FBG (102.46 ± 15.09 mg/dl vs. 95.92 ± 10.88 mg/dl, P = 0.017). The results revealed that CRD patients had significantly lower blood oxygen saturation than the control group (96.36 ± 3.81 vs. 98.51 ± 0.75, P < 0.001), whereas no significant differences were observed regarding the lipid profiles markers. CONCLUSION CRD patients have lower levels of vitamin C in their plasma and their diet than do healthy matched people; they also have higher oxidative stress and inflammatory markers than healthy people, which are risk factors for predicting metabolic complications.

Abstract
Asthma is an oxidative stress related disease, but associations with asthma outcomes are poorly studied in adults. We aimed to study the associations between several biomarkers related to oxidative stress and various asthma outcomes.Cross-sectional analyses were conducted in 1388 adults (mean age 43 years, 44% with asthma) from the Epidemiological Study of the Genetics and Environment of Asthma (EGEA2). Three blood antioxidant enzyme activities (biomarkers of response to oxidative stress) and exhaled breath condensate 8-isoprostanes and plasma fluorescent oxidation products (FlOPs) levels (two biomarkers of damage) were measured. Associations between biomarkers and 1) ever asthma and 2) asthma attacks, asthma control and lung function in participants with asthma were evaluated using regression models adjusted for age, sex and smoking.Biomarkers of response were unrelated to asthma outcomes. Higher 8-isoprostane levels were significantly associated with ever asthma (odds ratio for one interquartile range increase 1.28 (95% CI 1.06-1.67). Among participants with asthma, 8-isoprostane levels were negatively associated with adult-onset asthma (0.63, 0.41-0.97) and FlOPs levels were positively associated with asthma attacks (1.33, 1.07-1.65), poor asthma control (1.30, 1.02-1.66) and poor lung function (1.34, 1.04-1.74).Our results suggest that 8-isoprostanes are involved in childhood-onset asthma and FlOPs are linked to asthma expression.

Abstract
BACKGROUND As for the association of vitamin D receptor (VDR) gene polymorphisms with susceptibility to pediatric asthma, results of published studies yielded conflicts. A systematic review was conducted on the relationship between childhood asthma and VDR gene polymorphisms, including ApaI (rs7975232), BsmI (rs1544410), FokI (rs2228570), and TaqI (rs731236). METHODS PubMed, Web of Science, CBM (Chinese Biomedical Database), CNKI (China National Knowledge Infrastructure), and Wanfang (Chinese) database were searched for relevant studies. Pooled odds ratios (OR) with 95% confidence interval (CI) were calculated. RESULTS Overall results suggested that there was a statistically significant association between ApaI polymorphism and childhood asthma in homozygote model (OR = 1.674, 95%CI = 1.269-2.208, P < 0.001) and allele model (OR = 1.221, 95%CI = 1.084-1.375, P = 0.001). Stratification by ethnicity revealed a statistical association in Asians (OR = 1.389, 95%CI = 1.178-1.638, P < 0.001). There was some evidence of an association between BsmI polymorphism and childhood asthma in the homozygote (OR = 1.462, 95%CI = 1.016-2.105, P = 0.041) and allele models (OR = 1.181, 95%CI = 1.006-1.386, P = 0.042). This association reached significance only in the Caucasian group (OR = 1.236, 95%CI = 1.029-1.485, P = 0.023). For FokI, a statistical association was detected in dominant model (OR = 1.281, 95%CI = 1.055-1.555, P = 0.012); this association was significant in allele model (OR = 1.591, 95%CI = 1.052-2.405, P = 0.028) in Caucasian. CONCLUSION ApaI polymorphism plays a particular role in childhood asthma in Asians. FokI polymorphism may be connected with pediatric asthma in Caucasian population. And BsmI polymorphism marginally contributes to childhood asthma susceptibility, while there might be no association between TaqI polymorphism and childhood asthma risk.

Abstract
Gender differences in asthma incidence, prevalence and severity have been reported worldwide. After puberty, asthma becomes more prevalent and severe in women, and is highest in women with early menarche or with multiple gestations, suggesting a role for sex hormones in asthma genesis. However, the impact of sex hormones on the pathophysiology of asthma is confounded by and difficult to differentiate from age, obesity, atopy, and other gender associated environmental exposures. There are also gender discrepancies in the perception of asthma symptoms. Understanding gender differences in asthma is important to provide effective education and personalized management plans for asthmatics across the lifecourse.

Abstract
BACKGROUND The association between vitamin D receptor (VDR) polymorphisms and asthma risk has been inconsistently investigated, but published studies demonstrated conflicting results. The aim of the current study was to investigate the impact of TaqI, BsmI, ApaI, and FokI VDR polymorphisms on asthma disease by using a meta-analysis approach. METHODS Following the preferred reporting items for systematic reviews and meta-analyses guidelines, a systematic search and meta-analysis of the literature were conducted. Subgroup analyses were performed to detect potential sources of heterogeneity from selected study characteristics. RESULTS A total of 2,097 cases and 1,968 controls in eight case-control studies were included in meta-analyses. A significant association was found between TaqI polymorphisms and asthma risk [OR 1.488 (95 % CI 1.019-2.174); P = 0.040] in a codominant model. In the same way, BsmI was significantly associated with asthma risk [OR 2.017 (95 % CI 1.236-3.851); P = 0.017] in the codominant model. The homozygote BB BsmI genotype was found to confer significant asthma risk. FokI polymorphism was marginally associated with asthma risk [OR 1.187 (95 % CI 0.975-1.446); P = 0.088] in the codominant model. In contrast, no significant association was found between ApaI polymorphism and asthma risk. Subgroup analyses revealed that gender and age modified significantly the association between FokI polymorphisms and asthma risk (P = 0.035 and 0.013, respectively). Publication year and serum 25(OH) D level tended, marginally, to moderate the association between FokI polymorphism and asthma risk. CONCLUSION TaqI, BsmI, and FokI VDR polymorphisms contribute to asthma susceptibility. The association between FokI polymorphism and asthma risk is influenced by study characteristics.

Abstract
Reactive oxygen species (ROS) are thought to have effects on T-cell function and proliferation. Low concentrations of ROS in T cells are a prerequisite for cell survival, and increased ROS accumulation can lead to apoptosis/necrosis. The cellular redox state of a T cell can also affect T-cell receptor signaling, skewing the immune response. Various T-cell subsets have different redox statuses, and this differential ROS susceptibility could modulate the outcome of an immune response in various disease states. Recent advances in T-cell redox signaling reveal that ROS modulate signaling cascades such as the mitogen-activated protein kinase, phosphoinositide 3-kinase (PI3K)/AKT, and JAK/STAT pathways. Also, tumor microenvironments, chronic T-cell stimulation leading to replicative senescence, gender, and age affect T-cell susceptibility to ROS, thereby contributing to diverse immune outcomes. Antioxidants such as glutathione, thioredoxin, superoxide dismutase, and catalase balance cellular oxidative stress. T-cell redox states are also regulated by expression of various vitamins and dietary compounds. Changes in T-cell redox regulation may affect the pathogenesis of various human diseases. Many strategies to control oxidative stress have been employed for various diseases, including the use of active antioxidants from dietary products and pharmacologic or genetic engineering of antioxidant genes in T cells. Here, we discuss the existence of a complex web of molecules/factors that exogenously or endogenously affect oxidants, and we relate these molecules to potential therapeutics.

Abstract
BACKGROUND Asthma is associated with increased inflammation, oxidative stress and abnormal immune system function. We determined the distributions of several essential trace minerals and assessed their relationships to factors that are associated with the pathophysiological status of patients with mild/moderate asthma. METHODS We enrolled 25 asthmatic patients and 25 healthy subjects. We measured: blood trace minerals, zinc (Zn), copper (Cu) and selenium (Se); oxidative stress markers thiobarbituric acid reactive substances (TBARS); antioxidant enzyme activities; percentages of CD4 and CD8 lymphocyte subsets; high-sensitivity C-reactive protein (hs-CRP); and a lung function index (FEV1/FVC%). RESULTS Compared with healthy subjects, asthmatics had lower concentrations of Zn and Se; higher Cu concentrations, and Cu/Zn and Cu/Se ratios; and lower antioxidant enzyme glutathione peroxidase (GPx), glutathione reductase (GR) and catalase activities. Significantly increased concentrations of hs-CRP, TBARS and CD4/CD8 lymphocyte ratios were also observed. Furthermore, plasma TBARS or hs-CRP concentrations were negatively associated with Se concentrations, but were positively associated with Cu/Se ratios. CD4/CD8 lymphocyte ratios were inversely correlated with Se, while it was positively correlated with Cu/Se ratio. FEV1/FVC% was also significantly correlated with Se concentrations, and Cu/Se and Cu/Zn ratios. CONCLUSIONS Abnormal distributions of these trace minerals may aggravate oxidative damage and inflammation, increased CD4/CD8 lymphocyte ratios and decreased lung function in asthma.

Abstract
BACKGROUND Oxidative stress in an important hallmark of asthma and much research has therefore focused on the predominant antioxidant in the lungs, namely the tripeptide glutathione. MAJOR CONCLUSIONS In lung samples of patients with asthma increased levels of glutathione are typically observed, which appear to relate to the level of pulmonary inflammation and are therefore regarded as an adaptive response to the associated oxidative stress. Also in blood samples increased total GSH levels have been reported, representing the systemic inflammatory component of the disease. In addition, a number of the antioxidant enzymes involved in the maintenance of the GSH/GSSG ratio as well as enzymes that utilize GSH have been found to be altered in the lungs and blood of asthmatics and will be summarized in this review. Very few studies have however linked enzymatic alterations to GSH levels or found that either of these correlated with disease severity. Some animal studies have started to investigate the pathophysiological role of GSH biochemistry in asthma and have yielded surprising results. Important in this respect is the physiological role of the GSH redox equilibrium in determining the outcome of immune responses, which could be deregulated in asthmatics and contribute to the disease. SCOPE OF REVIEW Clinical data as well as animal and cell culture studies regarding these aspects of GSH in the context of asthma will be summarized and discussed in this review. This article is part of a Special Issue entitled: Biochemistry of Asthma.
