Effect of Omega-3 and Probiotic Dietary Supplements on Elevated High Sensitivity C-reactive Protein (Hs-CRP) as a Marker of Low-grade Inflammation
Effect of Omega-3 and Probiotic Dietary Supplements on Elevated High Sensitivity C-reactive Protein (Hs-CRP) as a Marker of Low-grade Inflammation: Targeting Inflammation and Intestinal Barrier Function in the Elderly and Obese
Study objectives:
Immunity, Inflammation, and Brain Function To determine the effect of supplements with probiotics, Omega-3 and Vitamin D on the inflammatory marker highly sensitive CRP (primary outcome), markers of inflammation (secondary outcome), and gastrointestinal barrier function (secondary outcome) in elderly and obese cohorts that exhibit elevated inflammation at baseline.
Mobility To determine the effect of supplements with probiotics, Omega-3 and Vitamin D on joints, bones, and muscles by means of the WOMAC questionnaire, sit/stand test (muscle function) and CTX-I (cartilage degradation) as secondary endpoints in elderly and obese cohorts that exhibit elevated inflammation at baseline.

Description
Inclusion Criteria:
- 65-80 years old for elderly arms
- 25-65 years old for obese arms
- screening hs-CRP of 1.5-6 mg/L for elderly
- screening hs-CRP of 2-10 mg/L for obese
- BMI 18.5-27 for elderly
- BMI 28-40 for obese
- Signed informed consent prior to any study related procedures
- Prospect to start the study the latest 6 weeks after the screening visit although preferably as soon as they receive the screening results
- Willing to abstain from regular consumption of probiotic supplements, products containing probiotic bacteria
- Willing to abstain from regular consumption of medication known to alter gastrointestinal functions for at least 4 weeks prior to the time of the study inclusion
- Willing to fast at least 5 hours during the sugar-permeability-test and receive a standardised breakfast (e.g. Cereal bar) or other standardised meal
- Accepting to drink at least 1.5 litres of provided water in one day, during the two time points where the sugar test is performed
Exclusion Criteria:
- Diagnosis of type 1 and/or type 2 diabetes
- Current or within 4 weeks use of probiotic supplement prior to inclusion
- More than 4 hours/week exercise habits
- Immobile, defined as the inability to participate in all study related procedures
- Dietary intake of fatty fish, fish oils containing omega-3 or pure omega- 3 supplements more than 2 times/week
- History of complicated gastrointestinal surgery
- Diagnosed Inflammatory Bowel Disease (IBD)
- Current diagnosis of psychiatric disease/s or syndromes
- Systemic use of antibiotics and/or steroid medication in the last 4 months prior to inclusion time
- Use of any NSAID (Non-Steroidal Anti-Inflammatory Drugs) more than 3 times a week for the last 2 months and any time 3 days prior inclusion or at any time 3 days prior the barrier function test
- Consumption of any NSAID up until 7 days prior to inclusion
- Any condition which could interfere with the intestinal barrier function (e.g. gluten sensitivity, lactose intolerance, celiac disease, IBS, IBD) as decided by the principal investigators´ discretion
- Drinking more than 9 standard cups of alcohol per week and/or more than 3 standard cups of alcohol per occasion.
- Regular smoking, use of snuff, nicotine or e-cigarette use
- Regular use, for more than three times a week for the last 2 months and any time 7 days prior to inclusion, of medications which according to the principal investigator can have an anti-inflammatory effect or affect in any way the intestinal barrier function or have an impact on the study analysis (e.g. laxatives, anti-diarrheal, anti-cholinergic).
- Any disorder which according to the principal investigator can have an anti-inflammatory effect and/or can affect the intestinal barrier function, or that can impact an adequate analysis of the study outcomes
- After being included in the study, starting with a medication/treatment or medical intervention that could potentially influence the study participation and/or the study analysis (e.g. the event of a fracture)
- Radical change in diet (e.g. becoming vegetarian or if they discover that they are lactose intolerant) during the study period
- Allergic to fish
- Allergic to milk- or soy protein

Intervention / Treatment |
---|---|
Experimental: Probiotics and Omega-3/vitamin D Supplements- Elderly
|
The first supplement we would like to assess is named VNP and is composed by Omega-3 Active and vitamin D. It contains a total of 1100 mg fish oils: 640 mg Omega-3 and with 300 mg eicosapentaenoic acid (EPA), 220 mg docosahexaenoic acid (DHA) plus 200 IU Vitamin D per daily dose (2 capsules). The second supplement we investigate is four-strain probiotics combination based on the commercially available formulation HOWARU® by DuPont; two capsules containing 10 billion CFU total (supplied by Pfizer but manufactured by Danisco, DuPont). The probiotic specific composition, contains equal amounts of each strain per capsule (1.25 x 109 CFU each): Bifidobacterium lactis Bi-07, Lactobacillus paracasei Lpc-37, Lactobacillus acidophilus NCFM, Bifidobacterium lactis Bl-04. One capsule contains 5 billion CFU (Swedish milliards). |
