Effectiveness and Safety of Lactobacillus Acidophilus LA85 in Preventing Antibiotic-Associated Diarrhea
Study Details
Study Description
Brief Summary
This randomized, placebo-controlled, double-blind clinical trial aims to evaluate the efficacy and safety of probiotics as food supplements in preventing antibiotic-associated diarrhea. The study will involve 82 patients who will be randomly assigned to one of two groups: an experimental group receiving a probiotic containing Lactobacillus acidophilus LA85, and a placebo group. The primary outcomes measured include the number of days until the onset of diarrhea, the duration of diarrhea (if it occurs), gastrointestinal quality of life evaluation using the GIQLI questionnaire, and overall patient satisfaction.

Detailed Description
This randomized, placebo-controlled, double-blind clinical trial aims to assess the effectiveness and safety of probiotics as food supplements in preventing antibiotic-associated diarrhea. The study will enroll 82 patients who will be randomly assigned to either the experimental group or the placebo group. Participants in the experimental group will receive a probiotic supplement containing Lactobacillus acidophilus LA85, while those in the placebo group will receive a non-active substitute.
The outcomes include the following measurements:
-
Number of days until the onset of diarrhea.
-
Duration of diarrhea, if it occurs.
-
Evaluation of gastrointestinal quality of life using the GIQLI questionnaire.
-
Overall patient satisfaction with the intervention. Throughout the trial, a double-blind approach will be maintained, ensuring that both the participants and the investigators are unaware of the treatment assignments. This helps minimize bias and ensures the reliability of the results. To assess the efficacy and safety of probiotics, data will be collected and analyzed using appropriate statistical methods. The number of days until the onset of diarrhea will be compared between the two groups, as well as the duration of diarrhea if it occurs. Gastrointestinal quality of life will be evaluated using the GIQLI questionnaire, which measures various aspects related to gastrointestinal well-being. Additionally, overall patient satisfaction with the intervention will be assessed. By conducting this comprehensive clinical trial, we aim to provide valuable insights into the potential benefits and safety of probiotics as food supplements in preventing antibiotic-associated diarrhea. The results obtained will contribute to evidence-based recommendations for healthcare professionals and may have implications for improving patient outcomes and quality of life.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Placebo Comparator: Placebo group Composition: 400mg maltodextrin (excipient)； Capsule total weight: 400mg； Primary conditioning: HPMC Capsules (Hydroxypropyl Methylcellulose)； Secondary conditioning：Cardboard case Secondary packaging content：14 capsules / blister, 1 blisters per case Dosage regimen: Take one capsule daily before meals； Storage：Store in a cool, dry place without exposure to the sun. |
Other: Probiotic Lactobacillus acidophilus LA85
Through a randomized double-blind placebo-controlled method, the patients were randomly divided into placebo group and probiotic intervention group, and took probiotics once a day for 14 consecutive days.
