About this study
Official title: Intervention Study on the Effects of a Probiotic Yoghurt Drink on the Immune System and Further Physiological Parameters in Patients With Atopic Dermatitis and Healthy Persons
The study was performed to investigate the effects of a probiotic supplementation containing Lactobacillus paracasei Lpc-37, Lactobacillus acidophilus 74-2 and Bifidobacterium animalis subsp. lactis DGCC 420 (B. lactis 420) on clinical, immunological and faecal parameters in healthy volunteers and in patients with atopic dermatitis (AD).
Read the detailed description
Recent studies suggest that oral bacteriotheraphy with probiotic bacteria might be useful to alleviate atopic dermatitis in infants. There are few indications about the effect of probiotics in the management of atopic dermatitis in adults.
As a precondition for participating in this study, the subjects were provided information in writing and verbally about the details of the study. Informed consent was obtained from all volunteers. Before the beginning of the study, all participants were subject to a medical examination in the Clinic for Dermatology and Dermatologic Allergology of the Friedrich Schiller University Jena. The AD was diagnosed according to the atopy-score of Diepgen. Severity of eczema was evaluated by using the SCORAD score. A skin prick test was performed for the exclusion of type 1 sensitivity to cow's milk.
The study was designed as a placebo-controlled and cross-over study. After a 3-week run-in period the 30 participants (15 healthy subjects and 15 patients with AD) were randomized to receive either 200 ml/d of a probiotic drink containing L. paracasei Lpc-37, L. acidophilus 74-2 and B. lactis 420 or 200 ml/d of a placebo drink for 8 weeks. After a 2-week washout period the intervention was crossed between the groups and the respective products were consumed for another 8 weeks followed by a 2-week washout period. Venous blood and fresh stool samples were collected before the beginning and at the end of each period. In AD patients the Scoring of atopic dermatitis (SCORAD) was assessed by the same physician every 4 weeks and 2 weeks after the wash-out period, respectively.

Who may be eligible to take part?
The sponsor lists 9 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Apr 2008. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
SCORAD change in patients with AD taken at baseline and after 4 and 8 weeks, respectively -change in phagocytic and oxidative burst activity of monocytes and granulocytes at baseline and after 8 weeks (time frame: 8 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
