Abstract Title: 

Suppression of tumorigenesis: modulation of inflammatory cytokines by oral administration of microencapsulated probiotic yogurt formulation.

Abstract: 

The objective of this study was to examine the ability of a novel microencapsulated probiotic yogurt formulation to suppress the intestinal inflammation. We assessed its anticancer activity by screening interleukin-1, 6, and 12 (IL-1, 6, 12), secretory levels of tumor necrosis factor-alpha (TNF-α), interferon-gamma (IFN-γ), prostaglandin E(2)  (PGE(2)), and thromboxane B2 in the digesta obtained from the duodenum, jejunum, proximal, and distal segments of the ileum of C57BL/6J-Apc(Min)/J mice. Formulation-receiving animals showed consistently lower proinflammatory cytokines' levels when compared to control group animals receiving empty alginate-poly-L-lysine-alginate (APA) microcapsules suspended in saline. The concentrations of IL-12 found in serum in control and treatment group animals were significant: 46.58 ± 16.96 pg/mL and 158.58 ± 28.56 pg/mL for control and treatment animals, respectively. We determined a significant change in plasma C-reactive protein: 81.04 ± 23.73 ng/mL in control group and 64.21 ± 16.64 ng/mL in treatment group. Western blots showed a 71% downregulation of cyclooxygenase-2 (COX-2) protein in treatment group animals compared to control. These results point to the possibility of using this yogurt formulation in anticancer therapies, in addition to chronic gut diseases such as Crohn's disease, irritable bowel syndrome (IBS), and inflammatory bowel disease (IBD) thanks to its inflammation lowering properties.

Abstract Title: 

Probiotic yogurt consumption may improve gastrointestinal symptoms, productivity, and nutritional intake of people living with human immunodeficiency virus in Mwanza, Tanzania.

Abstract: 

The gut-associated lymphoid tissue is a major site of human immunodeficiency virus (HIV) activity and significantly influences disease prognosis. Reducing immune activation due to gastroenteritis may thus help slow disease progression. Probiotic microorganisms have considerable immunomodulatory effects at the level of the gut-associated lymphoid tissue. A probiotic yogurt initiative was thus established in Mwanza, Tanzania, to improve gastrointestinal (GI) integrity and reduce the incidence and severity of opportunistic infections among people with HIV. The research objective was to retrospectively evaluate the effects of yogurt supplemented with Lactobacillus rhamnosus as an adjunct to the diet of people living with HIV on systemic and GI symptoms, daily routine activities, and nutritional intake. Eighty-five people with HIV consuming probiotic yogurt and 86 controls were interviewed. Demographics and HIV disease stage were comparable between groups. Probiotic yogurt consumers reported an ability to work a median of 2 hours more daily (P = .01), experienced a lower fever incidence (P = .01), and were more likely to achieve daily nutrient requirements for vitamin A, several B complex vitamins, and calcium (P = .02). Antiretroviral users experienced less drug-induced stomach pain (P = .02) and a lower overall impact of GI symptoms on routine activities (P = .03). The results of this study need be further substantiated because of limits imposed by the observational, retrospective study design; however, results suggest that yogurt supplemented with L rhamnosus may effectively alleviate GI symptoms and improve productivity, nutritional intake, and tolerance to antiretroviral treatment among people with HIV in Mwanza.

Abstract Title: 

Probiotics-containing yogurts suppress Helicobacter pylori load and modify immune response and intestinal microbiota in the Helicobacter pylori-infected children.

Abstract: 

BACKGROUND:  The benefits of probiotics to the pediatric Helicobacter pylori infection remain uncertain. We tested whether the H. pylori-infected children have an altered gut microflora, and whether probiotics-containing yogurt can restore such change and improve their H. pylori-related immune cascades.METHODS: We prospectively included 38 children with H. pylori infection confirmed by a positive¹³C-urea breath test (UBT) and 38 age- and sex-matched noninfected controls. All of them have provided the serum and stool samples before and after 4-week ingestion of probiotics-containing yogurt. The serum samples were tested for the TNF-α, IL-10, IL-6, immunoglobulin (Ig) A, G, E, pepsinogensI and II levels. The stool samples were tested for the colony counts of Bifidobacterium spp. and Escherichia coli. The follow-up UBT indirectly assessed the H. pylori loads after yogurt usage.RESULTS:  The H. pylori-infected children had lower fecal Bifidobacterium spp. count (p = .009), Bifidobacterium spp./E. coli ratio (p = .04), serum IgA titer (p = .04), and pepsinogens I/II ratio (p

Abstract Title: 

Effects of Probiotics on Biomarkers of Oxidative Stress and Inflammatory Factors in Petrochemical Workers: A Randomized, Double-blind, Placebo-controlled Trial.

Abstract: 

BACKGROUND: The aim of the current study was to determine effects of probiotic yoghurt and multispecies probiotic capsule supplementation on biomarkers of oxidative stress and inflammatory factors in petrochemical workers.METHODS: This randomized, double-blind, placebo-controlled trial was done among petrochemical workers. Subjects were randomly divided into three groups to receive 100 g/day probiotic yogurt (n = 12) or one probiotic capsule daily (n = 13) or 100 g/day conventional yogurt (n = 10) for 6 weeks. The probiotic yoghurt was containing two strains of Lactobacillus acidophilus and Bifidobacterium lactis with a total of min 1× 10(7) CFU. Multispecies probiotic capsule contains seven probiotic bacteria spices Actobacillus casei 3 × 10(3), L. acidophilus 3 × 10(7), Lactobacillus rhamnosus 7 × 10(9), Lactobacillus bulgaricus 5 × 10(8), Bifidobacterium breve 2 × 10(10), Bifidobacterium longum 1 × 10(9) and Streptococcus thermophilus 3 × 10(8) CFU/g. Fasting blood samples were obtained at the beginning and end of the trial to quantify biomarkers of oxidative stress and inflammatory factors.RESULTS: Although a significant within-group decrease in plasma protein carbonyl levels was seen in the probiotic capsule group (326.0± 308.9 vs. 251.0 ± 176.3 ng/mL, P = 0.02), the changes were similar among the three groups. In addition, significant within-group decreases in plasma iso prostaglandin were observed in the probiotic supplements group (111.9 ± 85.4 vs. 88.0 ± 71.0 pg/mL, P = 0.003) and in the probiotic yogurt group (116.3 ± 93.0 vs. 92.0 ± 66.0 pg/mL, P = 0.02), nevertheless there were no significant change among the three groups.CONCLUSIONS: Taken together, consumption of probiotic yogurt or multispecies probiotic capsule had beneficial effects on biomarkers of oxidative stress in petrochemical workers.

Abstract Title: 

Probiotic Lactobacillus spp. diminish Helicobacter hepaticus-induced inflammatory bowel disease in interleukin-10-deficient mice.

Abstract: 

Clinical and experimental evidence has demonstrated the potential role of probiotics in the prevention or treatment of inflammatory bowel disease. Probiotic clones with direct immunomodulatory activity may have anti-inflammatory effects in the intestine. We investigated the roles of tumor necrosis factor alpha (TNF-alpha)-inhibitory Lactobacillus clones with a pathogen-induced murine colitis model. Murine-derived probiotic lactobacilli were selected in vitro for their ability to inhibit TNF-alpha secretion by Helicobacter hepaticus-stimulated macrophages. Interleukin-10 (IL-10)-deficient mice were treated with probiotic Lactobacillus reuteri in combination with Lactobacillus paracasei and then challenged with H. hepaticus. Ten weeks postinoculation, the severity of typhlocolitis was assessed by histologic examination of the cecocolic region. Intestinal proinflammatory cytokine responses were evaluated by real-time quantitative reverse transcriptase PCR and immunoassays, and the quantities of intestinal H. hepaticus were evaluated by real-time PCR. Intestinal colonization by TNF-alpha-inhibitory lactobacilli reduced intestinal inflammation in H. hepaticus-challenged IL-10-deficient mice despite similar quantities of H. hepaticus in cocolonized animals. Proinflammatory colonic cytokine (TNF-alpha and IL-12) levels were lowered in Lactobacillus-treated animals. In this H. hepaticus-challenged IL-10-deficient murine colitis model, lactobacilli demonstrated probiotic effects by direct modulation of mucosal inflammatory responses.

Abstract Title: 

Yogurt Containing the Probacteria Lactobacillus acidophilus Combined with Natural Antioxidants Mitigates Doxorubicin-Induced Cardiomyopathy in Rats.

Abstract: 

Probiotics and antioxidants have a definite improving effect in cardiovascular diseases. This study aims at mitigating doxorubicin toxicity on cardiac function through consuming a functional food. Five groups of adult male Sprague-Dawley rats were used along 22 weeks. Group I received 30 g/kg/day food enriched with yogurt, green tea extract, and carrots (80, 0.84, and 100 g/kg diet, respectively) from the first week, group II received carvedilol 30 mg/kg/day orally from week 17, group III received both carvedilol and tested food, and groups IV and V were +ve and -ve control groups, respectively. In week 17, cardiomyopathy was induced by i.p. injection of 2.5 mg/kg doxorubicin every 48 h for 2 weeks. Histopathological and electrophysiological examinations and biochemical analysis were done. Lipid peroxidation, antioxidant effect, heart failure compensatory mediators, and proinflammatory cytokines were assessed. Tested food normalized time between the start of Q wave and the end of T wave on electrocardiogram (QT interval) and heart rate compared to the doxorubicin group (P

Abstract Title: 

Amelioration of Chemotherapy-Induced Intestinal Mucositis by Orally Administered Probiotics in a Mouse Model.

Abstract: 

BACKGROUND AND AIMS: Intestinal mucositis is a frequently encountered side effect in oncology patients undergoing chemotherapy. No well-established or up to date therapeutic strategies are available. To study a novel way to alleviate mucositis, we investigate the effects and safety of probiotic supplementation in ameliorating 5-FU-induced intestinal mucositis in a mouse model.METHODS: Seventy-two mice were injected saline or 5-Fluorouracil (5-FU) intraperitoneally daily. Mice were either orally administrated daily saline, probiotic suspension of Lactobacillus casei variety rhamnosus (Lcr35) or Lactobacillus acidophilus and Bifidobacterium bifidum (LaBi). Diarrhea score, pro-inflammatory cytokines serum levels, intestinal villus height and crypt depth and total RNA from tissue were assessed. Samples of blood, liver and spleen tissues were assessed for translocation.RESULTS: Marked diarrhea developed in the 5-FU groups but was attenuated after oral Lcr35 and LaBi administrations. Diarrhea scores decreased significantly from 2.64 to 1.45 and 0.80, respectively (P

Abstract Title: 

Daily intake of probiotic as well as conventional yogurt has a stimulating effect on cellular immunity in young healthy women.

Abstract: 

BACKGROUND/AIMS: The aim of this work was to study the effects of daily yogurt consumption on the cellular immunity of young healthy women and to compare a conventional with a probiotic product.METHODS: 33 young healthy women (22-29 years) consumed 100 g/day of either probiotic or conventional commercially available yogurt for 2 weeks and 200 g/day for another 2 weeks followed by a 2-week washout period with no fermented food at all. Before the intervention and after each phase, a complete white blood count was done, the percentage of activated CD69+ T lymphocytes after stimulation of whole blood with pokeweed mitogen was determined as well as the natural cytotoxicity of peripheral blood mononuclear cells against a human erythroleukemic target cell line (K562). All analyses were done by flow cytometry.RESULTS: In the probiotic group only, the numbers of cytotoxic T lymphocytes (CD3+CD16+CD56+) increased significantly (+30.8% with p = 0.001, +22.1 and +32.7% with p = 0.002, for T2, T3 and T4 compared to T1). There were no major changes for other cell populations, and all remained within the physiological range. In both groups, the expression of CD69 on T lymphocytes increased after yogurt consumption, especially on CD8+ (conventional: T2 +23%, T3 +27.2%, probiotic: T2 +15.7%; T3 +10.8% compared to T1) and to a lesser extent on CD4+ (conventional: T2 +7.7%, T3 +14.9%, probiotic: T2 +4% compared to T1. The cytotoxic activity also augmented following the intake, this effect persisting after cessation of consumption. However, there were no significant differences between the probiotic and the conventional yogurt group.CONCLUSION: Daily yogurt intake has a stimulating effect on cellular immune functions, but in this study the probiotic product did not perform better than the traditional one.
