BACKGROUND The aging process can lead to a decline in cellular immunity. Therefore, the elderly could benefit from safe and effective interventions that restore cellular immune functions. OBJECTIVE We determined whether dietary supplementation with the known immunostimulating probiotic Bifidobacterium lactis HN019 could enhance aspects of cellular immunity in elderly subjects. DESIGN Thirty healthy elderly volunteers (age range: 63-84 y; median: 69 y) participated in a 3-stage dietary… 

Figures and Tables from this paper

Impact of consumption of different levels of Bifidobacterium lactis HN019 on the intestinal microflora of elderly human subjects.

Dietary supplementation with B. lactis HN019 significantly increased the number of resident bifidobacteria and reduced the enterobacteria counts, and similar trends were observed for lactobacilli and enterococci.

Immunomodulating potential of supplementation with probiotics: a dose-response study in healthy young adults.

No solid effect on the immune function of young healthy adults supplemented with even high doses of B. animalis ssp.

Daily ingestion of fermented milk containing Lactobacillus casei DN114001 improves innate defense capacity in healthy middle-aged people

Results showed that daily intake of fermented milk containing Lactobacillus casei DN114001 could have a positive effect in modulating the innate immune defense in healthy-middle-age people.

Immunomodulatory effects of a probiotic drink containing Lactobacillus casei Shirota in healthy older volunteers

Consumption of a probiotic drink containing LcS improved NK cell activity and tended to produce a more anti-inflammatory cytokine profile in an older population.

Consumption of Bifidobacterium lactis Bi-07 by healthy elderly adults enhances phagocytic activity of monocytes and granulocytes

It is shown for the first time that the probiotic Bi-07 may provide health benefits to elderly individuals by improving the phagocytic activity of monocytes and granulocytes and the effects of some probiotics and prebiotics may last longer than in adults.

Nutraceuticals and Immune Restoration in the Elderly

Results from human clinical trials evaluating the use of nutraceuticals to support immune restoration in the elderly have been largely inconsistent and additional clinical trials using consistent outcome measures are needed, which will require a cooperative commitment from the nutr pharmaceutical industry and academia.

Exploring the Effect of Probiotics, Prebiotics, and Postbiotics in Strengthening Immune Activity in the Elderly

Although the clinical evidence on this topic is limited and the initial findings await clarification through future studies with large sample sizes and proper study designs, they highlight the necessity for additional research in this field, especially in light of the ongoing COVID-19 pandemic.

Effects of Bifidobacterium lactis HN019 and Prebiotic Oligosaccharide Added to Milk on Iron Status, Anemia, and Growth Among Children 1 to 4 Years Old

Consumption of probiotic- and prebiotic-fortified milk for a period of 1 year reduced the risk of being anemic and iron deficient and increased weight gain among 1- to 4-year-old preschoolers.



Enhancement of natural immune function by dietary consumption of Bifidobacterium lactis (HN019)

The results demonstrate that dietary consumption of B. lactis HN019 can enhance natural immunity in healthy elderly subjects, and that a relatively short-term dietary regime is sufficient to impart measurable improvements in immunity that may offer significant health benefits to consumers.

Enhancing immunity by dietary consumption of a probiotic lactic acid bacterium (Bifidobacterium lactis HN019): optimization and definition of cellular immune responses

Dietary consumption of the probiotic bacterium B. lactis HN019 enhanced immune function of two different types of leucocytes; the degree of enhancement was increased by consuming B. milkis in an oligosaccharide-rich substrate.

Effects of one year of supplementation with zinc and other micronutrients on cellular immunity in the elderly.

Although plasma Zn increased significantly in the 100 mg Zn treatment group, concentrations of Zn in erythrocytes, mononuclear cells, polymorphonuclear leukocytes, and platelets were not significantly increased by zinc supplementation.

Nutrition and immunity in the elderly: modification of immune responses with nutritional treatments.

Nutritional deficiency must be treated in the elderly to reduce infectious risk and possibly slow the aging process, and supplementation with high pharmacologic doses of a single nutrient may be useful for improving immune responses of self-sufficient elderly people living at home.

The effect of dietary supplementation with vitamins A, C and E on cell-mediated immune function in elderly long-stay patients: a randomized controlled trial.

It is concluded that supplementation with the dietary antioxidants vitamins A, C and E can improve aspects of cell-mediated immune function in elderly long-stay patients.

Acute oral toxicity and bacterial translocation studies on potentially probiotic strains of lactic acid bacteria.

Immunomodulation of human blood cells following the ingestion of lactic acid bacteria.

Nonspecific, anti-infective mechanisms of defense can be enhanced by the ingestion of specific lactic acid bacteria strains that can be used as nutritional supplements to improve the immune function of particular age groups, i.e., the neonate or the elderly.

Natural killer cell activity in elderly men is enhanced by beta-carotene supplementation.

It is shown that long-term beta-carotene supplementation enhances NK cell activity in elderly men, which may be beneficial for viral and tumoral surveillance.

Enhancement of natural and acquired immunity by Lactobacillus rhamnosus (HN001), Lactobacillus acidophilus (HN017) and Bifidobacterium lactis (HN019).

Results suggest that supplementation of the diet with L. rhamnosus, L. acidophilus or B. lactis is able to enhance several indices of natural and acquired immunity in healthy mice.
