The aim of this clinical study was to determine the impact of the consumption of chicken eggs enriched with n-3 polyunsaturated fatty acids, selenium, vitamin E, and lutein on micro- and ...macrovascular endothelium-dependent dilation, inflammation biomarkers, and oxidative stress levels in participants with chronic coronary syndrome (CCS). This was a double-blind, placebo-controlled clinical study that included 30 CCS participants (9 women, 21 men) randomized into the control group (N = 15), who ate ordinary chicken eggs (three per day), and the Nutri4 group (N = 15), who ate enriched eggs (three per day) for 21 days. Microvascular and macrovascular endothelium-dependent vasodilation was evaluated by measuring forearm skin post-occlusive reactive hyperemia (PORH) and acetylcholine-induced dilation (AChID) and the flow-mediated dilation (FMD) of the brachial artery, respectively. The serum lipid profile, anti- and proinflammatory cytokine levels, serum concentration of nitric oxide synthase (NOS) isoforms, and oxidative stress biomarkers were measured before and after the diet protocols. Enriched, but not regular, chicken eggs significantly improved microvascular PORH and AChID and macrovascular FMD, increased the serum concentration of inducible NOS, decreased serum triglyceride levels, and decreased proinflammatory cytokine IL-17A and TGF-1β levels compared to initial measurements. Patients with CCS can benefit from the consumption of enriched chicken eggs due to improved lipid biomarkers, a more favorable anti-inflammatory milieu, and improved vascular relaxation at micro- and macrovascular levels.
This study aimed to test the effect of n-3 polyunsaturated fatty acid (PUFA)-enriched hen egg consumption on serum lipid and free fatty acid profiles, inflammatory and oxidative stress biomarkers, ...and microvascular reactivity in patients with coronary artery disease (CAD). Forty CAD patients participated in this study. Of those, 20 patients had acute CAD (Ac-CAD), and 20 patients had chronic CAD (Ch-CAD). The control group (N = 20) consumed three regular hen eggs/daily (249 mg n-3 PUFAs/day), and the n-3 PUFAs group (N = 20) consumed three n-3 PUFA-enriched hen eggs/daily (1053 g n-3 PUFAs/day) for 3 weeks. Serum n-3 PUFA concentration significantly increased (in all CAD patients), while LDL cholesterol and IL-6 (in Ac-CAD patients), and hsCRP and IL-1a (in all CAD patients) significantly decreased in the n-3 PUFAs group. Glutathione peroxidase (GPx) activity significantly decreased, and forearm skin microvascular reactivity in response to vascular occlusion (postocclusive reactive hyperemia (PORH)) remained unchanged in both the n-3 PUFAs and control groups in total CAD, Ac-CAD, and Ch-CAD patients. Potentially, n-3 PUFA-enriched hen eggs can change the free fatty acid profile to a more favorable lower n6/n3 ratio, and to exhibit mild anti-inflammatory effects but not to affect microvascular reactivity in CAD patients.
Objective:
Ischemic heart disease is the leading cause of death at a global level. A healthy lifestyle, and especially a healthy diet, can have the effect of reducing the risk of subsequent ...cardiovascular events and mortality. The aim of this study was to examine the effect of hen eggs enriched with n-3 polyunsaturated fatty acids (n-3 PUFAs), vitamin E, selenium and lutein consumption on oxidative stress level and microvascular endothelium function in patients with existing chronic coronary syndrome (CCS).
Design and method:
A total of 30 patients (9 women and 21 men) with existing CCS participated in this study. The participants were divided in two groups; Control group (N = 15) who ate three regular hen eggs per day (n-3 PUFAs 146 mg, vitamin E 0.595 mg, selenium 0.0183 mg, lutein 0.11mg/per egg), and Nutri4 group (N = 15) who ate three enriched hen eggs per day (n-3 PUFAs 432 mg, vitamin E 1.098 mg, selenium 0.0191 mg, lutein 0.616 mg/per egg) for three weeks. Peripheral microvascular reactivity in response to vascular occlusion (PORH), and iontophoresis of acetylcholine (AChID) and sodium nitroprusside (SNPID), as well as serum lipid and fatty acids profile, pro- and anti-inflammatory cytokines level, as well as biomarkers of oxidative stress and antioxidant capacity were measured before and after the respective diet protocol.
Results:
Consumption of Nutri4 eggs significantly decreased serum triglycerides levels and n6/n3 PUFAs ratio, decreased levels of cytokines IL-17A and TGF-1beta, and improved endothelium-dependent microvascular PORH and AChID, but not endothelium-independent response in patients with CCS. Consumption of both Nutri4 and regular hen eggs did not affect biomarkers of oxidative stress and antioxidant capacity in CCS patients.
Conclusions:
Consumption of hen eggs enriched with n-3 PUFAs, vitamin E, selenium and lutein for three weeks induced an anti-inflammatory response, a favorable effect on lipid and fatty acids profile, especially on triglycerides levels and n6/n3 PUFAs ratio, as well as an improved endothelium-dependent peripheral microvascular reactivity in patients with CCS.
Paraneoplastic syndrome includes symptoms that occur far from the primary tumor, and despite unclear pathogenesis, these conditions are thought to be caused by substances secreted by the neoplasm or ...by the effect of antibodies directed at the tumor, which cross- react with other tissues.
Systemic sclerosis (SSc) is a chronic, autoimmune disease characterized by inflammation, vasculopathy, and fibrosis of the skin and internal organs. Immunological response in SSc is still poorly ...understood. Cytokines play a significant role in this process leading to vasculopathy and fibrosis. In this cross-sectional study, we aimed to investigate serum levels of Th-17-related cytokines, IL-17 and IL-22, and to determine their correlation to the clinical association in SSc patients. Serum IL-17 and IL-22 levels were examined in 42 SSc patients and 29 healthy individuals. Associations between serum IL-17 and IL-22 levels and the duration of the disease, the extent of skin fibrosis, capillaroscopic findings, and involvement of the internal organs were explored. Serum IL-17 levels were not different in SSc and the control group. Serum IL-22 levels were significantly elevated in SSc patients compared to healthy individuals (
p
= 0.04). A positive correlation was found between the IL-22 sera levels and interstitial lung disease (
p
= 0.007). These results suggest IL-22 as a potential biomarker in SSc-related interstitial lung disease.
Objective: Functional food (FF) is a food with presumably additional health benefits beyond its nutritional effects. We have been investigating health effects of consumption of hen eggs enriched with ...n-3 polyunsaturated fatty acids (n-3PUFAs) in healthy young sedentary populations, athletes and patients with acute and chronic coronary syndrome. Hereby, summarized data are presented to provide overall conclusions on the effect of n-3 PUFAs enriched eggs consumption on microvascular function, blood biochemical markers of inflammation and serum lipid profile of these participants. Design and method: Randomized controlled clinical interventional studies were conducted on a total of 90 healthy young (sedentary or athletes) and 40 cardiovascular participants. Participants were given n-3PUFAs enriched hen eggs (app.1 g n-3PUFAs (3 pcs)/ day for 3 consecutive weeks or regular eggs; n-3PUFAs 245 mg/day). Microvascular blood flow in response to various stimuli was assessed in skin microcirculation by laser Doppler flowmetry. Serum lipid profile, free fatty acids profile and various proinflammatory, anti-inflammatory and oxidative stress markers were measured. The study protocol and procedures conformed with the standards set by the latest revision of the Declaration of Helsinki, were approved by the Institutional Ethical Committees and registered at ClinicalTrials.gov. Results: Young healthy sedentaries on n-3 PUFAs eggs had significantly lower cholesterol and higher HDL-cholesterol after protocol. Microvascular flow was significantly increased after n-3 PUFAs consumption in sedentary and athletes. Glutathione peroxidase (GPx) and SOD activity decreased. Cardiovascular patients: LDL cholesterol and IL-6 (in Ac-CAD patients), and hsCRP and IL-1a (in all CAD patients) significantly decreased in n-3PUFAs group. GPx activity decreased, while microvascular reactivity remained unchanged. Conclusions: Consumption of FF can enhance microvascular function in healthy young participants and athletes; this effect is not observed in cardiovascular patients. The difference probably occurred due to the duration of the dietary protocol and medications taken by cardiovascular patients. Modest anti-inflammatory effects were observed in all study groups that consumed FF. Consumption of eggs does not have adverse effects on serum lipid profile. On the contrary; consumption of FF has a beneficial effect on the n-3 to n-6 free fatty acids ratio in serum of participants.
This study investigated the effect of consumption of table eggs enriched with n-3 polyunsaturated fatty acids (n-3 PUFA), lutein, vitamin E and selenium on microvascular function, oxidative stress ...and inflammatory mediators in patients after acute coronary syndrome (ACS).
In a prospective, randomized, interventional, double-blind clinical trial, ACS patients were assigned to either the Nutri4 (N=15, mean age: 57.2 ± 9.2 years), or the Control group (N=13; mean age 56.8 ± 9.6 years). The Nutri4 group consumed three enriched hen eggs daily for three weeks, providing approximately 1.785 mg of vitamin E, 0.330 mg of lutein, 0.054 mg of selenium and 438 mg of n-3 PUFAs. Biochemical parameters, including serum lipids, liver enzymes, nutrient concentrations, serum antioxidant enzyme activity (catalase (CAT), glutathione peroxidase (GPx), superoxide dismutase (SOD)), and markers of oxidative stress (thiobarbituric acid reactive substances (TBARS) and ferric reducing ability (FRAP)), were assessed before and after the dietary interventions. Additionally, arterial blood pressure, heart rate, body composition, fluid status, anthropometric measurements, and skin microvascular blood flow responses to various stimuli (postocclusive reactive hyperemia (PORH), acetylcholine- (Ach ID), and sodium nitroprusside- (SNP ID)) were measured using laser Doppler flowmetry (LDF) throughout the study.
The intake of Nutri4 eggs led to a significant reduction in LDL cholesterol levels, while the levels of total cholesterol remained within the established reference values. Consuming Nutri4 eggs resulted in a 12.7% increase in serum vitamin E levels, an 8.6% increase in selenium levels, and demonstrated a favorable impact on microvascular reactivity, as evidenced by markedly improved PORH and ACh ID. Nutri4 eggs exerted a significant influence on the activity of GPx and SOD, with no observed changes in TBARS or FRAP values.
The consumption of Nutri4 eggs positively influenced microvascular function in individuals with ACS, without eliciting adverse effects on oxidative stress.
Uvod: Antisintetazni sindrom (ASS) je rijetka autoimunosna sustavna bolest koju karakteriziraju miozitis, artritis, Raynaudov sindrom, mehaničarske ruke i intersticijska bolest pluća. Materijali i ...metode: Prikazujemo 50-godišnjeg bolesnika sa znacima polimiozitisa i zahvaćanja plućnog intersticija uz pozitivna anti-Jo1 protutijela kod kojega je postavljena sumnja na antisintetazni sindrom. Rezultati: Liječen je glukokortikoidima, a potom je kao dodatna imunosupresivna terapija uveden azatioprin koji je isključen zbog jetrene lezije, a liječenje je nastavljeno ciklofosfamidom. U kasnijem tijeku bolesti pratila se radiološka regresija plućnih promjena te se kao terapija održavanja uvede mikofenolat mofetil. Zaključak: Ako ostane neprepoznat ASS dovodi do razvoja ireverzibilne plućne fibroze, međutim pravovremenom
primjenom imunosupresivne terapije može se poboljšati kvaliteta života i prognoza bolesnika s ASS-om.
