Plain English Summary

Background and study aims
About 1 in 3 older people who are admitted to hospital require treatment with antibiotics. An adverse effect of antibiotics is that they change the "healthy" bacteria that live in the gut. This results in diarrhoea in about 1 in 5 people who are treated with antibiotics. In addition to being distressing for the patient, diarrhoea may delay recovery from illness and prolong the hospital admission. Occasionally, antibiotic treatment results in an overgrowth of a potentially dangerous bacterium called C. difficile. This bacterium can cause a severe diarrhoeal illness that may require additional medical treatment and surgery and may cause death. There is some encouraging evidence that giving supplements of normal, "healthy" bacteria (called probiotics) by mouth together with antibiotics prevents diarrhoea. Probiotics are very safe and do not themselves cause illness in people with a normal immune system. We will use bacteria called lactobacilli that are normally found in the gut in healthy people. We intend to find-out exactly how effective and also how cost-effective this approach is.

Who can participate?
Patients aged 65 or over admitted to hospital and receiving antibiotics

What does the study involve?
Participants are randomly allocated to receive either the probiotic or a placebo (dummy) treatment daily for 21 days in addition to any other treatment. We document how many in each group go on to develop mild and severe diarrhoea and also how this affects their quality of life.

What are the possible benefits and risks of participating?

Scientific titleA multicentre, randomised, placebo controlled trial of lactic acid bacteria and bifidobacteria in the prevention of antibiotic-associated diarrhoea (AAD) and Clostridium difficile diarrhoea (CDD) in patients aged 65 years and over admitted to hospital and receiving antibiotics
Study acronymPLACIDE
Study hypothesisA probiotic food supplement is effective in preventing antibiotic-associated and Clostridium difficile diarrhoea in older people admitted to hospital and receiving antibiotics.
Ethics approval(s)Research Ethics Committee for Wales, 27/11/2008
ConditionAntibiotic-associated diarrhoea; C. difficile diarrhoea
Intervention1. Live bacteria of human origin: 2 strains of Lactobacillus acidophilus (CUL60, National Collection of Industrial, Food and Marine Bacteria [NCIMB] 30157 and CUL21, NCIMB 30156), Bifidobacterium bifidum (CUL20, NCIMB 30153), Bifidobacterium lactis (CUL34, NCIMB 30172). Prepared as lyophilised powder in a capsule containing 6 x 1010 organisms/capsule.
2. Identical formulation of inert placebo: maltodextrin

The dose of probiotic is prepared in 5 g lyophilised powder in a capsule - the placebo is a matched capsule with 5 g of maltodextrin. Dosing is daily for 21 days via the oral route. The total duration of follow-up is 8 weeks from the end of antibiotics to a maximum of 12 weeks if other courses of antibiotics are given.
Intervention typeSupplement
Primary outcome measureDuring antibiotic treatment and within 8 weeks of stopping antibiotics:
1. The occurrence of antibiotic associated diarrhoea (AAD)
2. The occurrence of C. difficile diarrhoea (CDD)
Secondary outcome measures1. Severity and duration of AAD
2. Abdominal symptoms (abdominal pain, bloating, flatus, nausea)
3. Severity and duration of CDD and incidence of recurrence within the study period
4. Incidence of pseudomembranous colitis (PMC), need for colectomy, death
5. Well-being and quality of life
6. Duration of hospital stay
7. Adverse effects
8. Acceptability of the probiotic preparation
9. Viability of the probiotic at point of administration
All of these outcomes will be measured during the period from participant recruitment to 8 weeks after stopping antibiotics, to a maximum of 12 weeks from recruitment.

10. Risk factors for ADD, CDD and severe disease (PMC, colectomy, death), assessed at participant recruitment
Overall study start date01/12/2008
Overall study end date01/03/2011
