Pediatricians increasingly prescribe probiotics for children, with a strong preference for single-strain options like Bacillus clausii. This study analyzed 22,500 prescriptions, revealing trends in probiotic use for pediatric health.

Area of Science:

  • Pediatrics
  • Microbiome Research
  • Pharmacology

Background:

  • Growing interest in probiotics for optimizing intestinal health in children and adults.
  • Increasing use of probiotics in pediatric clinical practice due to scientific evidence.
  • Probiotics are considered for therapeutic and preventive roles in various diseases.

Purpose of the Study:

  • To prospectively analyze probiotic prescription patterns among pediatricians.
  • To identify preferred probiotic strains and formulations in a pediatric tertiary care setting.

Main Methods:

  • Prospective, observational study at a single tertiary care center.
  • Involved 53 pediatricians and analysis of 22,500 prescriptions from electronic medical records (EMR).
  • Data collected for children aged 0 to 16 years.

Main Results:

  • Single-strain probiotic prescriptions constituted 77.20% (17,370/22,500) of all analyzed prescriptions.
  • Bacillus clausii was the most frequently prescribed single-strain probiotic (48.57%).
  • A common multi-strain combination included Streptococcus faecalis, Clostridium butyricum, Bacillus mesentericus, and Lactobacillus sporogenes (37.85%).

Conclusions:

  • Pediatricians demonstrate a significant preference for single-strain probiotics.
