The Novel Effects of a Hydrolyzed Polysaccharide Dietary Supplement on Immune, Hepatic, and Renal Function in Adults with HIV in a Randomized, Double-Blind, Placebo-Control Trial.

The primary objective of the study was to evaluate the effects of a hydrolyzed polysaccharide, rice bran arabinoxylan compound (RBAC), on immune, hepatic, and renal function in HIV + individuals. A 6-month randomized double-blind placebo-controlled trial was utilized to conduct the intervention. Forty-seven HIV + individuals on stable antiretroviral therapy were enrolled and randomly assigned to one of the 2 study conditions (n = 22 RBAC and n = 25 placebo) and consumed 3 gram/day of either compound for 6 months. Participants were assessed at baseline and 3 and 6 months follow-up for CD4+ and CD8+, liver enzymes, and kidney function. No side effects were reported, and liver and kidney markers remained nearly completely within normal limits. The percentage change in CD4+ was similar for the placebo (+2.2%) and RBAC (+3.1%) groups at 6 months follow-up. The percentage change in CD8+ count significantly decreased from baseline to 6 months in the RBAC group (-5.2%), whereas it increased in the placebo group (+57.8%; p = 0.04). The CD4+/CD8+ ratio improved clinically in the RBAC group from 0.95 (SD = 0.62) at baseline to 1.07 (SD = 0.11) at 6 months, whereas it declined in the placebo group from 0.96 (SD = 0.80) at baseline to 0.72 (SD = 0.59) at 6 months. Our results showed a statistically significant decrease in CD8+ count and a clinically significant increase in CD4+/CD8+ ratio for the RBAC group compared to the placebo group. Thus, the results of this study suggest that the immunomodulatory and antisenescent activities of RBAC are promising for the HIV population.

The Effect of a Polysaccharide-Based Multinutrient Dietary Supplementation Regimen on Infections and Immune Functioning in Multiple Sclerosis.

Multiple sclerosis (MS) is a progressive neurodegenerative disease associated with increased infection rates, chronic inflammation, and premature death. Optimization of nutritional status via dietary supplementation may improve immune function in people suffering from MS and lead to decreased rates of infection. Fifteen individuals with a diagnosis of relapsing-remitting MS for an average of 12.4 years (SD =7.4; R = 2, 25) were enrolled in a one-year open-label clinical trial. Participants consumed a broad-spectrum dietary supplement regimen containing polysaccharides, phytochemicals, antioxidants, vitamins, and minerals three times per day. The occurrence of infections and a panel of cytokines, growth factors, and T- and B-cell subsets were assessed at baseline and 12 months. Seven female and 8 male participants with an average age of 51.3 years (SD =7.2; R = 38, 65) completed the study. At the end of the intervention, participants had fewer total infections (M = 7.9, SD =8.1 at baseline and M = 2.5, SD =4.3 at 12-month follow-up). At 12 months, IL-2, TNF-α, EGF, and CD95 + CD34+ significantly increased, while IL-1ß significantly decreased. No major adverse effects were reported; only mild gastrointestinal intolerance was reported in four cases. A decreased occurrence of infection was observed in MS patients treated with 12 months of a polysaccharide-based multinutrient dietary supplement. Significant changes were also noted in several key biomarkers that would be physiologically favorable to the MS population. Thus, the results of this study suggest an immunomodulatory effect of the dietary supplement regimen studied.

The Effect of Broad-Spectrum Dietary Supplementation on Quality of Life, Symptom Severity, and Functioning in Multiple Sclerosis.

Multiple sclerosis (MS) is a progressive neurodegenerative disease that exerts a significant quality-of-life toll on patients. According to the literature, broad-spectrum dietary supplementation including a variety of nutrients, polysaccharides, and compounds may improve the quality of life, functionality, and symptom severity in people with MS. Individuals (n = 15) diagnosed with relapsing-remitting MS (RRMS) for an average of 12.4 years (SD = 7.4; R = 2, 25) were enrolled in a one-year open-label clinical trial in which they consumed a broad-spectrum dietary supplement regimen three times daily. Participants were assessed at baseline and at 3, 6, 9, and 12 months with the following: (1) Functional Assessment of MS (FAMS), (2) the EQ-5D-3L, (3) Beck Depression Inventory-II (BDI), (4) Health Conditions Discomfort Scale (HCDS), and (5) Self-Assessment of Severity of MS Symptoms Scale (SASMSSS). Participants included seven females and eight males (M age = 51.3 years; SD = 7.2; R = 38, 65). Few minor gastrointestinal effects were reported. At the end of the intervention, participants showed significant improvements in all outcome measures, particularly functionality on the FAMS, overall quality of life on the EQ-5D-3L, fewer depressive symptoms on the BDI, and improved severity of symptoms on the HCDS and the SASMSSS. Our results suggest that dietary supplementation containing a variety of nutrients can improve the quality of life, severity of disease symptoms, and functionality in MS patients. These findings are clinically promising for MS patients, given the lack of treatment options geared toward improving quality of life in this population.

The Effect of a Hydrolyzed Polysaccharide Dietary Supplement on Biomarkers in Adults with Nonalcoholic Fatty Liver Disease.

The primary objective of the study was to evaluate the effect of a hydrolyzed polysaccharide, Rice Bran Arabinoxylan Compound (RBAC), on biomarkers in adults with nonalcoholic fatty liver disease (NAFLD). A 90-day randomized double-blind placebo-controlled trial examined the effect of RBAC on complete blood count, liver enzymes, lipids, oxidative stress markers, cytokines, and growth factors. Twenty-three adults with NAFLD were enrolled and randomly assigned to one of the two study conditions (n = 12 RBAC and n = 11 placebo) and consumed 1 gram/day of either compound for 90 days. Subjects were assessed at baseline and 45 and 90 days. No adverse effects were reported. Alkaline phosphatase significantly decreased (-3.1%; SD = 19.9; F[1,19] = 5.1, p = 0.03) in the RBAC group compared to placebo. Percent monocytes (17.9%; SD = 18.3; F[1,19] = 5.9, p = 0.02) and percent eosinophils (30.6%; SD = 30.5; F[1,19] = 12.3, p < 0.01) increased in the RBAC group. IFN-γ (156%; SD = 131.8; F[1,19] = 4.2, p = 0.06) and IL-18 (29.1%; SD = 64; F[1,19] = 5.3, p = 0.03) increased in the RBAC group compared to placebo. Other improvements were noted for platelets, neutrophils, neutrophil-lymphocyte ratio, γ-glutamyl transferase, and 4-hydroxynonenal. RBAC had beneficial effects on several biomarkers that add to the known immunomodulatory activities of RBAC, which may be promising for people with NAFLD.
