Background and study aims
In the year 2006 37,3 million prescriptions of antibiotics were registered in Germany. Antibiotics are among the most prescribed drugs in this country. Antibiotic associated diarrhoea (AAD) is a frequent and severe condition. It appears in 10-25% of patients in hospitals undergoing antibiotic treatment and results not only in longer hospitalisation but also a higher risk for further complications. Clostridium difficile- associated diarrhoea (CDAD) is an especially severe form of AAD and occurs in 15-25% of all cases of AAD. Clostridium difficile is a naturally occurring bacteria of the healthy intestinal flora. Under suppression of the normal intestinal flora due to antibiotic treatment Clostridium difficile can grow and secrete toxins causing damage to the intestinal tissue. Patients suffering from a CDAD not only undergo a distinctive diarrhoea but may also develop life-threatening complications, e.g. pseudomembraneous colitis or toxic megacolon. AAD and CDAD are also a financial burden to the health care system. The development and evaluation of preventive strategies is one key public health challenge. In the absence of clinically evaluated alternatives, probiotics have been suggested to be help prevent
AAD and CDAD. However, data have so far been inconclusive and recently published analyses strongly recommended that large clinical trials should be run. Perenterol® forte is a non-prescription substance approved in Germany for symptomatic treatment of diarrhoea and treatment or prevention of travellers' diarrhoea or diarrhoea due to tube feeding. The active ingredient is Saccharomyces boulardii. Saccharomyces boulardii is considered the most promising probiotic substance for the prevention of AAD and CDAD and is the object of this trial.
Who can participate?
Every contractually capable adult who receives systemic (oral/intravenous) antibiotic treatment while hospitalised in one of our trial centres can participate after signing the written consent form, as long as they comply with inclusion and exclusion criteria.
What does the study involve?
Patients receive the drug Perenterol® forte or a dummy drug twice daily. The capsules are taken orally for the duration and one week following antibiotic treatment. The patient independently records his/her stool frequency and consistence in a diary during the treatment and for another 6 weeks after the treatment.
What are the possible benefits and risks of participating?
Risks due to participation in this trial are minimal.
Sac. boulardii is a living micro-organism which is able to cause generalized fungal infections under adverse circumstances (e.g. immune deficiency) by migration from the gastrointestinal tract into the blood stream or by external contamination of central venous catheters. Individual cases of these generalized fungal infections have been detected in hospitalised patients with central venous catheters additionally suffering from a severe underlying disease mostly localised in the gastrointestinal tract. Known side effects are flatulence and hypersensitivity reactions to the point of anaphylactic shock or sepsis.
Where is the study run from?
A number of German centres
When is study starting and how long is it expected to run for?
The recruitment started in June 2010. The first patient was recruited on 09/07/2010. The estimated end date of the study is 31/07/2012.
Who is funding the study?
German Federal Ministry of Education and Research (BMBF)
