NCT06791993

Brief Summary

This study aims to evaluate whether probiotics can help maintain a healthy gut microbiome in patients receiving prophylactic antibiotics during elective orthopedic surgery. Antibiotics, while effective in preventing infections, can disrupt the balance of gut bacteria, leading to dysbiosis. The study hypothesizes that the use of probiotics during the perioperative period can prevent or reduce this disruption, supporting gut health and overall well-being. The research seeks to answer whether combining probiotics with routine antibiotic prophylaxis can preserve gut microbiome balance and improve patient outcomes.

Outcome Measures

Primary Outcomes (1)

  • Maintenance of Gut Microbiome Balance

    Evaluate whether probiotic administration preserves gut microbiome balance during the perioperative period by assessing changes in microbial richness, diversity, and evenness. Shotgun metagenomic sequencing analysis will be used to measure microbial composition and diversity.

    2 weeks preoperatively (T0) to 1 month postoperatively (T4).

Secondary Outcomes (6)

  • Firmicutes/Bacteroidetes Ratio

    2 weeks preoperatively (T0) to 1 month postoperatively (T4).

  • Short-Chain Fatty Acid (SCFA) Production

    2 weeks preoperatively (T0) to 1 month postoperatively (T4).

  • Dysbiosis Index

    2 weeks preoperatively (T0) to 1 month postoperatively (T4).

  • Microbiome health index ( MHI) OR Microbiome health index for post-antiobiotic (MHI- A)

    2 weeks preoperatively (T0) to 1 month postoperatively (T4).

  • WHO-5 Well-being Index

    1 week preoperatively (T1) and 2 weeks postoperatively (T3).

  • +1 more secondary outcomes

Study Arms (2)

Routine Antibiotic Prophylaxis + Placebo

PLACEBO COMPARATOR

This arm receives routine antibiotic prophylaxis with a single dose of intravenous Cefazolin and a placebo capsule to match the probiotic intervention.

Drug: Placebo Capsule

Routine Antibiotic Prophylaxis + Probiotics

EXPERIMENTAL

This arm receives routine antibiotic prophylaxis with a single dose of intravenous Cefazolin and a dual-strain probiotic containing Human Milk Oligosaccharides (HMO).

Dietary Supplement: Probiotic with Human Milk Oligosaccharides (HMO)

Interventions

Participants will receive an inert placebo capsule that matches the probiotic capsule in size, shape, and color. The placebo will be administered orally twice daily, starting 2 weeks before surgery and continuing for 2 weeks postoperatively.

Routine Antibiotic Prophylaxis + Placebo

Participants will receive a dual-strain probiotic containing Human Milk Oligosaccharides (HMO) in capsule form. The probiotic will be administered orally twice daily, starting 2 weeks before surgery and continuing for 2 weeks postoperatively.

Also known as: Dual-Strain Probiotic
Routine Antibiotic Prophylaxis + Probiotics

You may not qualify if:

  • History of infection or antibiotic use within the last 12 weeks.
  • Use of routine probiotics, vitamins, or herbal supplements in the last 4 weeks.
  • Known allergy to beta-lactam or cephalosporin antibiotics.

Masking Details
In addition to participants, care providers, investigators, and outcomes assessors, the study's pharmacy personnel responsible for dispensing the intervention are also masked to the group assignments. Placebo and probiotic capsules are prepared to be identical in appearance and packaging, ensuring that no party involved in the trial can distinguish between the two interventions. Randomization and allocation are managed by an independent third party to maintain blinding integrity throughout the study.

Intervention Model
PARALLEL
Model Details: This study uses a parallel group design where participants are randomly assigned to one of two independent arms. One group receives routine antibiotic prophylaxis with a placebo capsule, while the other group receives routine antibiotic prophylaxis combined with a dual-strain probiotic containing Human Milk Oligosaccharides (HMO). The interventions are administered concurrently over the perioperative period to evaluate their effects on gut microbiome balance and patient recovery. Randomization and blinding ensure unbiased comparisons between the groups.
