RESUMO

The purpose of the present clinical trial was to determine the impact of zinc supplementation on serum liver enzymes, steatosis severity, lipid profile, and inflammatory status in overweight or obese children with nonalcoholic steatohepatitis (NASH). This randomized controlled trial was conducted by enrolling 60 children with NASH, aged 10-18 years old. The participants were randomly assigned to two groups that received either 30 mg/day of elemental zinc or placebo for 16 weeks. The severity of liver steatosis was evaluated using liver ultrasonography. Fasting blood samples were collected from each patient at the beginning and after 16 weeks of intervention to measure biochemical parameters. Following a 16-week intervention, zinc supplementation compared with placebo significantly decreased serum alanine aminotransferase (ALT) concentrations and high-sensitivity C-reactive protein and considerably enhanced HDL-cholesterol values. However, zinc intake had no considerable impact on aspartate aminotransferase, the severity of liver steatosis, anthropometric parameters, and other lipid indices versus the placebo group. Overall, zinc supplementation showed a promising impact on serum ALT, HDL-cholesterol, and inflammatory status in overweight or obese children suffering from NASH. Zinc supplementation may be a new strategy for the amelioration of NASH in overweight or obese children. This trial has been registered on the Iranian website for registration of clinical trials with the special ID of IRCT20200531047614N1 ( https://www.irct.ir/trial/48543 ).

RESUMO

Background: Red blood cell distribution (RDW), an index of the size variability of erythrocytes, is significantly associated with coronary stenosis and can strongly predict the mortality risk in coronary artery disease (CAD). The biological mechanisms involved are not fully understood but may include oxidative stress. We sought to investigate the relationship between RDW and markers of oxidative stress in patients with CAD. Methods: Participants were 112 consecutive patients referred to department of cardiac surgery for evaluation of chest pain. 32 patients had stable CAD, 40 patients had unstable CAD and 40 subjects were diagnosed as non-CAD. The levels of lipid peroxidation (TBARS) were measured in plasma and membrane samples by a fluorometric method. The plasma levels of glutathione (GSH) and total antioxidant capacity (TAC) were determined using spectrophotometric methods. Results: Lipid peroxidation levels were significantly higher in the erythrocyte membrane of stable CAD patients than non-CAD patients. The levels of TAC were significantly lower in both stable and unstable groups when compared to that of the control group (P< 0.019 and P< 0.001, respectively), but did not differ between stable and unstable CAD. In addition, there was no significant difference in the serum GSH levels among the study groups. Membrane TBARS was directly associated with RDW in three groups of study. Conclusions: We found an independent association between RDW levels and membrane lipid peroxidation in patients with CAD. This finding suggests that oxidative stress may be a potential underlying biological mechanism for increased RDW in CAD patients.

RESUMO

Objective: The purpose of this study was to evaluate the impact of isoflavone supplementation compared with placebo on endometrial histology and serum estradiol levels in premenopausal women with nonatypical endometrial hyperplasia. Materials and Methods: The present double-blindplacebo-controlled clinical trial was conducted on 100 women with nonatypical endometrial hyperplasia in the age range of 30 to 45 years. Participants were randomly assigned to receive 50 mg of isoflavone (n = 50) or placebos (n = 50) daily for three months. Both groups received the standard treatment of nonatypical endometrial hyperplasia. Endometrial biopsy and blood samples were taken at the baseline and three months after the intervention. The incidence of drug side effects was assessed as well. Results: After three months, 88.4% of isoflavone-administered subjects had a significant histological improvement compared to 68.9% subjects in the placebo group (P=0.02). There were no significant differences between the two groups in the changes of serum estradiol levels and the incidence of drug side effects. Conclusion: The findings of the present study demonstrated that the coadministration of 50 mg of isoflavones and medroxyprogesterone acetate increases the treatment efficacy in women with nonatypical endometrial hyperplasia. Clinical Trial Registration. This trial was registered on the Iranian website for clinical trial registration (https://www.irct.ir/trial/53553).

RESUMO

Background: This investigation was performed to assess the effects of alpha-lipoic acid (ALA) supplementation on psychological status and markers of inflammation and oxidative damage in patients with type 2 diabetes mellitus (T2DM) and coronary heart disease (CHD). Methods: This randomized, double-blind, placebo-controlled trial was performed in 60 patients with T2DM and CHD, aged 45-85 years. Patients were randomized into two groups to receive either 600 mg/day ALA (n = 30) or placebo (n = 30) for 12 weeks. Results: ALA supplementation significantly decreased Beck Depression Inventory index (BDI) (-5.1 ± 3.5 vs. -1.1 ± 4.8, P = 0.001) when compared with the placebo. ALA supplementation resulted also in a significant reduction of serum high sensitivity C-reactive protein (hs-CRP) (-0.8 ± 1.4 vs. +0.5 ± 0.6 mg/L, P < 0.001) and malondialdehyde (MDA) (-0.3 ± 0.2 vs. -0.1 ± 0.3 µmol/L, P = 0.003), and a significant increase in plasma total antioxidant capacity (TAC) levels (+ 26.8 ± 36.0 vs. -4.6 ± 43.4 mmol/L, P = 0.007) when compared with the placebo. ALA intake upregulated transforming growth factor beta (TGF-ß) (P = 0.03) and downregulated gene expression of interleukin-1 (IL-1) (P = 0.001) in peripheral blood mononuclear cells of patients with T2DM and CHD as well. Conclusions: ALA supplementation for 12 weeks in patients with T2DM and CHD had beneficial effects on BDI, hs-CRP, TAC, MDA values, and gene expression of IL-1 and TGF-ß.

RESUMO

Increasing evidence suggests that apelin and ghrelin may participate in atherogenesis. We sought to investigate whether the serum levels of apelin and ghrelin are significantly different in patients with coronary artery disease (CAD) compared to patients with nonsignificant coronary stenosis and determine the correlation between these adipokines and the severity of coronary stenosis. The study population included 31 stable CAD patients, 38 unstable CAD patients, and 39 non-CAD subjects. Serum levels of apelin and ghrelin, fasting blood glucose, lipid parameters, hs-CRP and hematological indices were determined in all groups using routine standard laboratory procedures. Serum apelin levels were significantly lower in patient with unstable CAD (0.354 ± 0.063 ng/mL) compared to stable CAD patients (0.401 ± 0.045 ng/mL, p = 0.003) and non-CAD subjects (0.415 ± 0.055 ng/mL, p<0.001). In addition, serum apelin levels were inversely correlated with the severity of coronary stenosis in CAD patients (p<0.05). However, there was no significant difference in ghrelin levels among the 3 groups. This data may suggest that the presence of unstable CAD may be associated with lower serum apelin which may indicate the potential role of this peptide in the progression and destabilization of coronary plaques.

RESUMO

Background: Growth differentiation factor-15 (GDF-15), a member of transforming growth factors, is a stress-responsive marker whose levels may significantly increase in response to pathological stresses associated with inflammatory tissue injuries such as unstable angina pectoris (USAP). This study evaluated the diagnostic value of GDF-15 in patients with USAP. Methods: The present cross-sectional study recruited 39 patients with USAP criteria and 30 patients with stable angina pectoris (SAP), referred to Shahid Beheshti Hospital, Kashan, Iran. All the patients with USAP had at least 1 coronary artery stenosis (>50%) in angiography. The control group comprised 42 healthy individuals. The serum levels of GDF-15 were measured in all the participants by ELISA. Also analyzed were the relationship between GDF-15 levels and thrombolysis in myocardial infarction (TIMI) and the Global Registry of Acute Coronary Events (GRACE) risk scores in the patients with USAP to determine the severity of the disease. Result: The study population consisted of 111 subjects, 62 women and 49 men, divided into 3 groups of USAP (n=39, mean age=60.07±14.10 y), SAP (n=30, mean age=67.56±9.88 y), and control (n=42, mean age=61.21±7.76 y). The mean serum level of GDF-15 in the USAP group was significantly different from the other 2 groups (P<0.001), while no significant difference was observed in this regard between the SAP and control groups (P=0.797). No correlation was found between the mean GDF-15 serum level and the GRACE (P=0.816) and TIMI (P=0.359) risk scores in the USAP group. Conclusion: The mean serum level of GDF-15 exhibited a rise in our patients with USAP. GDF-15 may be a diagnostic biomarker of USAP and its severity.

RESUMO

INTRODUCTION: This study assessed the effects of curcumin intake on psychological status, markers of inflammation and oxidative damage in patients with type 2 diabetes mellitus (T2DM) and coronary heart disease (CHD). METHOD: This randomized, double-blind, placebo-controlled trial was performed in 60 patients with T2DM and CHD, aged 45-85 years with 2- and 3-vessel CHD. Patients were randomized into two groups to receive either 1000 mg/day curcumin (n = 30) or placebo (n = 30) for 12 weeks. Using RT-PCR method, gene expression related to insulin metabolism and inflammatory markers on mononuclear cells from peripheral blood was evaluated. RESULT: Curcumin intake significantly decreased Pittsburgh Sleep Quality Index (PSQI) (ß -1.27; 95% CI, -2.27, -0.31; P = 0.01) compared to the placebo group. Curcumin intake caused a significant reduction in malondialdehyde (MDA) (ß -0.20 µmol/L; 95% CI, -0.36, -0.04; P = 0.01), significant increase in total antioxidant capacity (TAC) (ß 75.82 mmol/L; 95% CI, 3.400, 148.25; P = 0.04) and glutathione (GSH) levels (ß 63.48 µmol/L; 95% CI, 26.58, 100.37; P = 0.001) when compared with the placebo. Additionally, curcumin intake upregulated peroxisome proliferator-activated receptor gamma (PPAR-γ) (P = 0.01). CONCLUSION: Curcumin intake for 12 weeks in patients with T2DM and CHD had beneficial effects on PSQI, TAC, GSH, MDA values, and gene expression of PPAR-γ. This study was retrospectively registered in the Iranian website (www.irct.ir) for registration of clinical trials (http://www.irct.ir: IRCT20170513033941N63).

RESUMO

ATP-binding cassette transporter A1 (ABCA1) has a crucial role in removing intracellular cholesterol and plays a protective role against atherosclerosis. Therefore, genetic polymorphisms in this gene may alter the susceptibility to coronary artery disease (CAD). This study was aimed to examine the association of rs2230806 (c.1051 G > A; p.R219K) variation in the ABCA1 gene with CAD in a case-control design which was followed by a meta-analysis and in silico approach. In the case-control study, 300 subjects including 150 individuals with CAD and 150 healthy controls were recruited. The c.1051 G > A genotyping was done by polymerase chain reaction-restriction fragment length polymorphism method. In the meta-analysis, eligible studies were collected from PubMed, Google Scholar, and ScienceDirect databases and pooled odds ratio, heterogeneity, publication bias, and sensitivity analyses were carried. Finally, some bioinformatics tools were employed to assess the impacts of p.R219K variation on ABCA1 protein structure. Our case-control examination showed a statistically significant association between c.1051 G > A genetic polymorphism and CAD risk. In addition, the meta-analysis showed reliable significant associations between c.1051 G > A transition and risk of CAD in the Caucasian population. In silico analysis showed that the p.R219K substitution could alter the secondary structure, hydrophobicity pattern, and Ramachandran plot of ABCA1. These findings elucidate that the c.1051 G > A variation could be a genetic risk factor for CAD and it could be considered as a prognostic and predictive biomarker for susceptible individuals.

RESUMO

This study was performed to evaluate the effects of vitamin D and n-3 fatty acids' co-supplementation on markers of cardiometabolic risk in diabetic patients with CHD. This randomised, double-blinded, placebo-controlled trial was conducted among sixty-one vitamin D-deficient diabetic patients with CHD. At baseline, the range of serum 25-hydroxyvitamin D levels in study participants was 6·3-19·9 ng/ml. Subjects were randomly assigned into two groups either taking 50 000 IU vitamin D supplements every 2 weeks plus 2× 1000 mg/d n-3 fatty acids from flaxseed oil (n 30) or placebo (n 31) for 6 months. Vitamin D and n-3 fatty acids' co-supplementation significantly reduced mean (P = 0·01) and maximum levels of left carotid intima-media thickness (CIMT) (P = 0·004), and mean (P = 0·02) and maximum levels of right CIMT (P = 0·003) compared with the placebo. In addition, co-supplementation led to a significant reduction in fasting plasma glucose (ß -0·40 mmol/l; 95 % CI -0·77, -0·03; P = 0·03), insulin (ß -1·66 µIU/ml; 95 % CI -2·43, -0·89; P < 0·001), insulin resistance (ß -0·49; 95 % CI -0·72, -0·25; P < 0·001) and LDL-cholesterol (ß -0·21 mmol/l; 95 % CI -0·41, -0·01; P = 0·04), and a significant increase in insulin sensitivity (ß +0·008; 95 % CI 0·004, 0·01; P = 0·001) and HDL-cholesterol (ß +0·09 mmol/l; 95 % CI 0·01, 0·17; P = 0·02) compared with the placebo. Additionally, high-sensitivity C-reactive protein (ß -1·56 mg/l; 95 % CI -2·65, -0·48; P = 0·005) was reduced in the supplemented group compared with the placebo group. Overall, vitamin D and n-3 fatty acids' co-supplementation had beneficial effects on markers of cardiometabolic risk.

RESUMO

This study compared the effects of flaxseed and fish oil supplementation on cardiovascular risk parameters in diabetic patients with coronary heart disease. Participants were randomly allocated into three intervention groups to receive either 1,000 mg of omega-3 fatty acids from fish oil or 1,000 mg of omega-3 fatty acids from flaxseed oil or placebo (n = 30 each group) twice a day for 12 weeks. A significant reduction in insulin levels (.04) was observed following flaxseed oil and fish oil supplementation compared with the placebo. In addition, a significant reduction in high-sensitivity C-reactive protein (.02) was seen after flaxseed oil supplementation compared with the placebo and a significant increase in total nitrite (.001) was seen after flaxseed oil and fish oil intake compared with placebo. Additionally, a significant increase in total antioxidant capacity (p < .001) after consuming flaxseed oil and fish oil compared with placebo and glutathione levels (.001) after consuming fish oil compared with flaxseed oil and placebo was observed. Overall, our study revealed the beneficial effects of flaxseed oil and fish oil supplementation on few metabolic profiles. This study suggests that the effect of flaxseed oil in reducing insulin and increasing total nitrite and total antioxidant capacity is similar to fish oil.

RESUMO

Unstable angina pectoris (USAP) is a complex condition in which widespread coronary inflammatory processes have important implications for clearer understanding of its pathogenesis and also its treatment. This study aimed at evaluating the diagnostic as well as prognostic value of serum inflammatory markers of pentraxin-3 (PTX-3), Von Willebrand Factor (vWf) and C-X-C Motif Chemokine Ligand 13 (CXCL13) in such patients. Out of sixty-nine patients, thirty-nine had USAP, thirty had stable angina pectoris (SAP), and thirty-nine were healthy controls. For all participants, serum PTX-3, vWf and CXCL13 levels were measured using ELISA. For each patient with USAP, the Thrombolysis in Myocardial Infarction (TIMI) and the scores of Global Registry of Acute Coronary Events (GRACE) were calculated to determine the severity of the disease. We, then, analyzed the relation of PTX-3, vWf and CXCL13 levels with TIMI and GRACE scores in patients with USAP. Serum PTX-3, vWf and CXCL13 levels were significantly higher in USAP group than those in either SAP or control groups (p˂0.001). Strong correlation was observed between CXCL13 level and TIMI risk score (p=0.019). In receiver operating characteristic (ROC) curves, area under the curve (AUC) values of PTX3, vWf and CXCL13 for detection of USAP were 0.755, 0.751, and 0.906, respectively. The levels of serum PTX3, vWf and CXCL13 increased in patients with USAP. The notable correlation implied that CXCL13 might be a sensitive and specific biomarker for the diagnosis of USAP as well as its severity. It might also show additional diagnostic values when measured in combination with vWf.

RESUMO

BACKGROUND AND OBJECTIVE: Stroke is a devastating condition with long-term comorbidities including metabolic abnormalities. Alpha lipoic acid (ALA), with its antioxidant properties, might improve metabolic status of patients, though current evidence is still inclusive. This systematic review of randomized controlled trials (RCTs) was conducted to summarize the existing evidence regarding the effects of ALA supplementation on fasting glucose and lipid profiles among patients with stroke. METHODS: We searched Cochrane Library, EMBASE, MEDLINE, and Web of Science from 1990 until April 5th, 2018. The relevant randomized-controlled articles, based on defined key words, were included in the analyses. Two independent researchers investigated study eligibility, extracted data, and assessed the risk of bias for included studies. Heterogeneity among included studies was tested using Q-test and I2 statistics. Random-effects models were applied to pool the data and standardized mean differences (WMD) were considered as summary effect size. RESULTS: A total of five studies (140 patients in each intervention group) were included in our meta-analysis. The findings showed that ALA supplementation significantly decreased fasting glucose levels (WMD -36.93 mg/dL; 95% CI, -65.58, -8.28; P = 0.01; I2 = 85.0%) in patients with stroke. We found no significant effect of ALA supplementation on triglycerides (WMD -7.45 mg/dL; 95% CI, -51.35, 36.45; P = 0.739; I2 = 83.9%), total cholesterol (WMD -23.23 mg/dL; 95% CI, -48.07, 1.62; P = 0.067; I2 = 80.5%), LDL-cholesterol (WMD -10.46 mg/dL; 95% CI, -21.01, 0.09; P = 0.052; I2 = 47.4%) and HDL-cholesterol levels (WMD -3.02 mg/dL; 95% CI, -20.18, 14.14; P = 0.730; I2 = 85.8%). CONCLUSIONS: This meta-analysis suggested the beneficial impacts of ALA supplementation in improving fasting glucose of patients diagnosed with stroke.

RESUMO

BACKGROUND & AIMS: Melatonin may benefit diabetic people with coronary heart disease (CHD) through its beneficial effects on biomarkers of oxidative stress and cardio-metabolic risk. This investigation evaluated the effects of melatonin administration on metabolic status in diabetic patients with CHD. METHODS: This randomized, double-blind, placebo-controlled trial was conducted and involved 60 diabetic patients with CHD. Subjects were randomly allocated into two groups to receive either 10 mg melatonin (2 melatonin capsules, 5 mg each) (n = 30) or placebo (n = 30) once a day for 12 weeks. RESULTS: Compared with the placebo, melatonin supplementation resulted in significant increases in plasma glutathione (GSH) (+64.7 ± 105.7 vs. -11.1 ± 137.6 µmol/L, P = 0.02) and nitric oxide (NO) (+0.9 ± 4.7 vs. -3.3 ± 9.6 µmol/L, P = 0.03), and significant decreases in malondialdehyde (MDA) (-0.2 ± 0.3 vs. +0.1 ± 0.5 µmol/L, P = 0.007), protein carbonyl (PCO) (-0.12 ± 0.08 vs. +0.03 ± 0.07 mmol/mg protein, P < 0.001) and serum high sensitivity C-reactive protein (hs-CRP) levels (-1463.3 ± 2153.8 vs. +122.9 ± 1230.4 ng/mL, P = 0.001). In addition, taking melatonin, compared with the placebo, significantly reduced fasting plasma glucose (-29.4 ± 49.0 vs. -5.5 ± 32.4 mg/dL, P = 0.03), serum insulin concentrations (-2.2 ± 4.1 vs. +0.7 ± 4.2 µIU/mL, P = 0.008), homeostasis model of assessment-estimated insulin resistance (-1.0 ± 2.2 vs. +0.01 ± 1.6, P = 0.04), total-/HDL-cholesterol ratio (-0.18 ± 0.38 vs. +0.03 ± 0.35, P = 0.02) and systolic (-4.3 ± 9.6 vs. +1.0 ± 7.5 mmHg, P = 0.01) and diastolic blood pressure (-2.8 ± 7.3 vs. +0.1 ± 3.6 mmHg, P = 0.04). Melatonin treatment also significantly increased quantitative insulin sensitivity check index (+0.006 ± 0.01 vs. -0.004 ± 0.01, P = 0.01) and serum HDL-cholesterol (+2.6 ± 5.5 vs. -0.01 ± 4.4 mg/dL, P = 0.04). Supplementation with melatonin had no significant effect on other metabolic parameters. CONCLUSIONS: Overall, melatonin intake for 12 weeks to diabetic patients with CHD had beneficial effects on plasma GSH, NO, MDA, PCO, serum hs-CRP levels, glycemic control, HDL-cholesterol, total-/HDL-cholesterol ratio, blood pressures and parameters of mental health.

RESUMO

Synbiotics are known to exert multiple beneficial effects, including anti-inflammatory and antioxidant actions. The aim of this study was to evaluate the effects of synbiotic supplementation on carotid intima-media thickness (CIMT), biomarkers of inflammation, and oxidative stress in people with overweight, diabetes, and coronary heart disease (CHD). This randomized, double-blind, placebo-controlled trial was conducted and involved 60 people with overweight, diabetes, and CHD, aged 50-85 years old. Participants were randomly allocated into two groups to take either synbiotic supplements containing three probiotic bacteria spices Lactobacillus acidophilus strain T16 (IBRC-M10785), Lactobacillus casei strain T2 (IBRC-M10783), and Bifidobacterium bifidum strain T1 (IBRC-M10771) (2 × 109 CFU/g each) plus 800 mg inulin or placebo (n = 30 each group) for 12 weeks. Fasting blood samples were taken at baseline and after the 12-week intervention period to determine metabolic variables. After the 12-week intervention, compared with the placebo, synbiotic supplementation significantly reduced serum high-sensitivity C-reactive protein (hs-CRP) (- 3101.7 ± 5109.1 vs. - 6.2 ± 3163.6 ng/mL, P = 0.02), plasma malondialdehyde (MDA) (- 0.6 ± 1.0 vs. - 0.1 ± 0.3 µmol/L, P = 0.01), and significantly increased nitric oxide (NO) levels (+ 7.8 ± 10.3 vs. - 3.6 ± 6.9 µmol/L, P < 0.001). We did not observe any significant changes of synbiotic supplementation on other biomarkers of oxidative stress and CIMT levels. Overall, synbiotic supplementation for 12 weeks among people with overweight, diabetes, and CHD had beneficial effects on serum hs-CRP, plasma NO, and MDA levels; however, it did not have any effect on other biomarkers of oxidative stress and CIMT levels.

RESUMO

BACKGROUND AND AIMS: The objective of this investigation was to assess the effects of probiotic and selenium co-supplementation on indicators of mental health and metabolic profiles in diabetic people with coronary heart disease (CHD). METHODS: This randomized, double-blind, placebo-controlled trial was conducted among 54 diabetic people with CHD. Patients were randomly allocated into two groups to receive either 200 µg/day selenium plus 8 × 109 CFU/day probiotic (n = 27) or placebo (n = 27) for 12 weeks. RESULTS: Probiotic and selenium co-supplementation significantly decreased Beck Depression Inventory index (ß -1.46; 95% CI, -2.61, -0.31; P = 0.01) and Beck Anxiety Inventory index (ß -1.23; 95% CI, -2.33, -0.12; P = 0.02) compared with the placebo. Consuming probiotic plus selenium lowered fasting plasma glucose (ß -10.80 mg/dL; 95% CI, -17.68, -3.92; P = 0.003), serum insulin levels (ß -3.42 µIU/mL; 95% CI, -4.93, -1.90; P < 0.001), insulin resistance (ß -0.96; 95% CI, -1.45, -0.47; P < 0.001), and enhanced insulin sensitivity (ß 0.01; 95% CI, 0.007, 0.01; P < 0.001) compared with the placebo. Additionally, co-supplementation reduced triglycerides (ß -34.45 mg/dL; 95% CI, -56.18, -12.72; P = 0.003), VLDL- (ß -6.89 mg/dL; 95% CI, -11.23, -2.54; P = 0.003), total cholesterol (ß -18.13 mg/dL; 95% CI, -23.42, -2.83; P = 0.02) and high sensitivity C-reactive protein (ß -1043.28 ng/mL; 95% CI, -1929.67, -156.89; P = 0.02), and increased nitric oxide (ß 7.86 µmol/L; 95% CI, 5.63, 10.09; P < 0.001), total antioxidant capacity (ß 119.30 mmol/L; 95% CI, 63.04, 175.57; P < 0.001) and total glutathione (ß 154.16 µmol/L; 95% CI, 82.57, 225.74; P < 0.001) compared with the placebo. CONCLUSIONS: Probiotic and selenium co-supplementation to diabetic people with CHD improved indicators of mental health and metabolic profiles.
