Aloe vera supplementation improves cardiovascular risk factors in hemodialysis patients: A randomized, double-blind, placebo-controlled trial.

Objective: This study assessed the effects of Aloe vera supplementation on serum inflammatory factors, blood sugar and lipid profiles in hemodialysis patients. Materials and Methods: Totally, 50 hemodialysis patients were allocated randomly to either Aloe vera or placebo groups. The Aloe vera group received 2 Aloe vera capsules daily for 8 weeks (500 mg/day). Serum C-reactive protein (hs- CRP), Fasting blood glucose (FBS), and lipid profiles levels were evaluated at the baseline and the end of the eighth week. Results: Aloe vera supplementation for 8 weeks was associated with a significant reduction of serum hs- CRP (p=0.004), total cholesterol (p=0.01), low density lipoprotein (LDL) (p=0.02) leves and increased high density lipoprotein (HDL) (p=0.002) concentration in the hemodialysis patients. Conclusion: Aloe vera supplementation is beneficial in improvement of cardiovascular risk factors in hemodialysis patients.

Synbiotic supplement for treatment of iron deficiency anaemia in haemodialysis patients: A randomized controlled trial.

BACKGROUND: There is evidence that probiotics can increase the availability of iron. The aim of current study was to determine the effects of synbiotic supplementation on the haematological parameters and anaemia in haemodialysis patients. METHODS: This study was a randomized, double-blind, placebo-controlled trial. Fifty patients were randomly selected from the haemodialysis section of Vaseii Hospital, Sabzevar, Iran. Subjects in the symbiotic and control groups received 2 capsules of synbiotic supplement or placebo, respectively, once a day for 8 weeks. Blood samples were divided into two test tubes in equal volumes. Blood haemoglobin, haematocrit, transferrin saturation, red blood cells (RBCs), and total iron binding capacity (TIBC) were measured with auto-analyser. Ferritin was determined using Sandwich enzyme-linked immunosorbent assay (ELISA). RESULTS: Twenty tree patients in each group completed the study. Significant results were recorded in synbiotic groups regarding the concentration of blood haemoglobin, haematocrit, transferrin saturation, the number of RBCs, and serum ferritin compare to placebo group (P < .05). At the end of week 8, TIBC significantly decreased in synbiotic than placebo group (P < .05). CONCLUSION: Synbiotic supplementation could be a safe and promising candidate in improving anaemia in CKD patients.

Effect of Nigella sativa oil supplement on risk factors for cardiovascular diseases in patients with type 2 diabetes mellitus.

This study aimed to evaluate the effects of Nigella sativa oil on serum level of systemic inflammation, oxidative stress, fasting blood glucose (FBG), and lipid profile in patients with type 2 diabetes mellitus (T2DM). This double-blind randomized clinical trial study was based on 50 patients with T2DM. Patients were allocated randomly to either N. sativa oil or placebo groups. The intervention group received 1,000 mg N. sativa oil as two capsules, daily for 8 weeks, whereas the placebo group received a corresponding placebo. At baseline and the end of the study, 5 ml blood was collected from each patient after 14-hour fasting for measuring serum C-reactive protein (hs-CRP), malondialdehyde (MDA), FBS, and lipid profile. Analyses covariance was performed to compare investigated parameters between two groups, controlled for relevant covariates. Using N. sativa supplement was significantly associated with decrease in FBS (p < .001), triglyceride (p < .001), total cholesterol (p < .001), low-density lipoprotein cholesterol (p < .001), serum hs-CRP, MDA (p < .001) and increase in serum level of high-density lipoprotein cholesterol (p < .001) in intervention group compared with placebo group. Nigella sativa oil supplement has cardiovascular protective effects in patients with T2DM, by improving the lipid profile and glycemia, by reducing the C-reactive protein level and the lipid peroxidation.

A synbiotic supplement for inflammation and oxidative stress and lipid abnormalities in hemodialysis patients.

INTRODUCTION: Among the most important risk factors for cardiovascular disease in hemodialysis patients are high concentrations of serum inflammation markers, lipid profiles, and oxidative stress. The present study aimed to investigate the effects of a synbiotic supplement on serum systemic inflammation, oxidative stress markers, and lipid profile in hemodialysis patients. METHODS: Fifty hemodialysis patients were randomly allocated to synbiotic and placebo groups. The synbiotic group received 2 tablets per day of a synbiotic supplement (100 mg) Lactobacillus coagulans and fructo-oligosaccharides for 8 weeks; whereas the placebo group received a similar appearing placebo. At the beginning and end of the study, 5 mL blood was taken after 12-14 hours of fasting. FINDINGS: Mean values of serum C-reactive protein (hs-CRP) and malondialdehyde (MDA) significantly decreased in the synbiotic group at the end compared to the beginning of the study (P = 0.01). This reduction was significant in comparison with changes in the placebo group (P = 0.01). The synbiotic supplement also reduced serum total cholesterol (P = 0.001) and low-density lipoprotein cholesterol (LDL-c; P = 0.001) compared to the placebo group. DISCUSSION: The synbiotic supplement used improves serum hs-CRP and MDA, total cholesterol and LDL-c in hemodialysis patients, which are known risk factors for cardiovascular disease.

Effects of Synbiotics on Inflammatory Markers in Patients With Type 2 Diabetes Mellitus.

INTRODUCTION: With regard to the relationship between inflammation and insulin resistance and due to the lack of researches conducted about the effect of synbiotics on inflammatory markers in diabetes patients, this study was designed to investigate the effect of these markers. METHODS: A double-blind, placebo-controlled trial was conducted among 44 type 2 diabetes patients. They were randomized to symbiotic or placebo group. Patients in the symbiotic group received one symbiotic tablet daily for 8 weeks whereas the placebo group received 1 placebo tablet. The hs-CRP concentration, TNF-α and IL-6 were measured by using ELISA kits. The dietary intakes of patients were assessed at the first and the end of the study and analyzed by Nutritionist IV. Data were analyzed by using SPSS 16.0 via paired and independent t-test. RESULTS: Anthropometric and dietary data were not significantly different between the two groups at the first and the end of the study. The serum concentrations of hs-CRP, IL-6 and TNF-α decreased significantly in the symbiotic group at the end of week 8 compared to baseline (p<0.05). Also, no significant changes were seen in the placebo group (p>0.05). The reduction in inflammatory markers in the symbiotic group were significant in compared to the placebo group (P<0.05). CONCLUSIONS: Symbiotic supplementation can reduce serum hs-CRP, IL-6 and TNF-α concentrations, a risk factor for cardiovascular diseases.
