Eligibility Criteria

60 Years - 85 Years (Adult, Older Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • Willing to participate in the study and comply with its procedures

  • A stable body weight (≤5 % change) over the 3 months prior to screening.

Exclusion Criteria:

  1. Cold or flu-like (URTI) symptoms, with a Jackson Cold Scale score of >2; not otherwise explained by seasonal allergies
  2. Chronic disease such as, type-2 diabetes, cardiovascular diseases, gastrointestinal disorders, and rheumatoid arthritis, which in the Investigators judgment, precludes involvement in the study
  3. Oral antibiotics within 4 weeks prior to the screening visit
  4. Use of immunosuppressant drugs, systemic steroids or systemic antimicrobial medication (including suppositories) within the 4 weeks prior to the screening visit

  8. Planned change in current diet or exercise habits
  9. Habitual intake of probiotic supplements within 2 months before screening visit
  10. Have had gastrointestinal surgery (e.g. colectomy, cholecystectomy, gastric bypass); Appendectomy allowed. Laparoscopic surgeries (removal of polyps, cysts) are allowed.
  11. Have had any other condition or are taking a medication that the investigator believes would interfere with the objectives of the study, pose a safety risk, or confound the interpretation of the study results;
  12. Any change in medication or supplement intake in the 30 days prior to baseline

  17. Use of herbal remedies and supplements with potential anti-inflammatory properties for the duration of the study, which in the Investigators judgement may have an impact on the objectives of the study.
  18. Have a current malignant disease or any current concomitant end-stage organ disease, which, in the Investigator's judgment, contraindicates participation in the study;
  19. Individuals who, in the opinion of the investigator, are considered to be poor clinical attendees or unlikely for any reason to be able to comply with the trial.

5. Study Description

Brief Summary
To investigate the effectiveness of two doses of the probiotic strain Bif-038 on markers of low-grade inflammation in a elderly population
Detailed Description
The study is a randomized, double-blind, 3-arm, placebo-controlled pilot study in an elderly population (60-85 years) with low-grade inflammation (hs-CRP 2-10 mg/L) comparing two doses daily intake of Bif-038 at 1 and 10 billion CFU to placebo for 12 weeks. The subjects will receive either one of the two test products or the placebo product daily for a period of 12 weeks. During the entire study period, five visits are scheduled. The subjects will participate in two screening visits; a baseline visit, a visit after 6 weeks of intervention and an end-of-study visit after 12 weeks of intervention. Visit 1 and 2 are screening- and recruitment visits with at least two weeks apart. Only participants with a hs-CRP within 2.0-10.0 mg/L will be invited for the second screening visit. Participants with repeated hs-CRP levels within 2.0-10.0 mg/L will be invited for baseline visit 3, to be included and randomized in the study. At the screening visits the eligibility will be checked after the participants have given their written informed consent. Blood samples and stool samples will be collected during the study and subjects will be asked to complete questionnaires and a dietary diary. No sample size calculations were performed due to the exploratory nature of a pilot study design. Planned number to include is 20 subjects per study arm, thus 60 subjects in total.

Title
Change in Health-related Quality of Life
Description
The effect of daily intake of Bif-038 on changes in heath-related quality of life measured by Short Form 36 questionnaire (SF36). Comparison between all three treatment groups. The 36 questions (items) are transformed to 8 dimensions (Physical Functioning, Social Functioning, Role limitations due to physical problems, Role limitations due to emotional problems, Mental health, Energy/vitality, Pain, and General health perception). These 8 dimensions are then again aggregated into two summary scores, physical component and mental health between 0-100 for all dimensions. The lower the score the more disability and the higher the score the less disability.
Time Frame
6 and 12 weeks
Title
Change in mental health
Description
The effect of daily intake of Bif-038 on change in mental health measured by Depression Anxiety Scale (DASS-21). Comparison between all three treatment groups. The DASS yields three subscale scores for depression, anxiety, and tension/stress. The higher the score the more severe with the following ranging: Depression: Normal: 0-9, Mild: 10-12, Moderate:13-20, Severe: 21-27, and Extremely severe: 28-42. Anxiety: Normal: 0-6, Mild: 7-9, Moderate: 10-14, Severe:15-19, and Extremely severe: 20-42. Stress: Normal: 0-10, Mild:11-18, Moderate:19-26, Severe: 27-34, and Extremely severe: 35-42.
Time Frame
6 and 12 weeks
Title
