Outcome measures
Primary outcome
Ex vivo phagocytic capacity of monocytes and granulocytes in whole blood.
Secondary outcome
1. Ex vivo oxidative burst capacity of monocytes and granulocytes in whole blood;
2. NK cell activity in PBMC;
3. NK cell number in PBMC;
4. Gut microbiota composition (e.g. % of bifidobacteria, lactobacilli);
5. Faecal parameters: pH, short-chain fatty acids, lactic acid;
6. Tolerance and safety parameters: tolerance by questionnaires, adverse events, laboratory safety parameters.
Background summary
In this trial the effect of the test product will be compared to the control product on the non-specific immune function in elderly. Subjects will be using the study product twice a day for 6 weeks.
Study objective
Usage of the Pentagon Module will improve nonspecific immune function.
Study design
1. Visit 0 = screening (Day -21 max.);
2. Visit 1 = Day 1 (start of intervention);
3. Visit 2 = Day 21;
4. Visit 3 = Day 42 (end of intervention);
5. Follow Up phone call = Day 49.
Intervention
Duration of intervention: 6 weeks (total duration study maximal 10 weeks).
Test group: Twice daily intake of the test product named Pentagon module.
Control group: Twice daily intake of the control product which is an isocaloric
product.
Both products are powders that need to be solved prior to intake.
After screening for eligibility weight will be measured 3 times, stool and blood samples will be taken 3 times and tolerance questionnaires will be completed
during 22 days.
(Serious) adverse events will be monitored from start study until 1 week after
completion of the intervention period.
