260There is a relative high prevalence of constipation and antibiotic-associated diarrhoea (AAD) in the elderly residents of nursing homes, mainly due to high antibiotic and medication usage. Constipation and diarrhoea causes a substantial burden on lives of the frail elderly and significantly reduces the quality of life (QoL). In addition, these circumstances lead to a higher workload for healthcare workers and treatment of constipation and diarrhoea increase costs in healthcare. There are indications that the gastrointestinal microbiome is altered in conditions, such as constipation and AAD. Research indicates that probiotics show potential in the treatment of constipation, AAD and infectious diarrhoea. Probiotics can restore the aberrant gastrointestinal microbiome and thereby possibly treat/prevent constipation and diarrhoea in the frail elderly population. To illustrate, a previous pilot study of probiotic administration in elderly residents of a nursing home demonstrated a reduced prevalence of constipation and diarrhoea stool types and a higher prevalence of ideal stool types during the intervention compared to the baseline period. These promising results demand for a confirmatory study in this population.
The primary objective is to assess the effect of a probiotic intervention and a non-probiotic intervention on bowel habits of elderly (>80 years on average) in several nursing homes in the Netherlands.
A randomized, double-blind, superiority, multicentre trial. In this trial a probiotic fermented milk drink will be compared to a non-probiotic drink on its potential to improve bowel habits. Both drinks are commercially available in the supermarket. After a run-in period of 2 weeks, 260 subjects will be randomized (1:1) into either the probiotic fermented milk arm (n=130) or the non-probiotic drink arm (n=130), both for a period of 10 weeks.
The study population consists of 260 frail elderly of relatively high age (>80 years old on average) living in several nursing homes in The Netherlands. One arm receives daily one bottle (65 ml) of Yakult Original (YOR), a probiotic fermented milk drink containing at least 6,5*10^9 colony forming units (cfu) of Lactobacillus casei Shirota (LcS), for 10 consecutive weeks without changing the regular diet. The other arm will receive a dairy milk drink (AH Basic Dairy Peach Drink, 65 mL) for 10 consecutive weeks, also without changing the regular diet.
The change in bowel habits of the subjects will be measured according to two main study parameters; (a) Stool-quality according to the 7-point Bristol stool chart, and (b) defecation frequency, measured as number of stools per time unit.
