Insights
Probiotic prophylaxis significantly reduced ventilator-associated pneumonia (VAP) and diarrhea in mechanically ventilated children. This strategy offers a promising approach to prevent nosocomial infections in the Pediatric Intensive Care Unit (PICU).
Area of Science:
- Pediatric Intensive Care
- Infectious Disease Prevention
- Microbiome Research
Background:
- Ventilator-associated pneumonia (VAP) is a common nosocomial infection in Pediatric Intensive Care Units (PICUs).
- Preventing nosocomial infections is critical to combat antibiotic resistance.
- Probiotics are being explored as a novel strategy for infection prevention.
Purpose of the Study:
- To investigate the efficacy of probiotic prophylaxis in preventing VAP in mechanically ventilated children.
- To assess the impact of probiotics on reducing VAP incidence in a pediatric intensive care setting.
Main Methods:
- A randomized, double-blind clinical trial involving 72 mechanically ventilated children (under 12 years).
- Participants received either Limosilactobacillus reuteri DSM 17938 probiotic or a placebo twice daily.
- VAP screening was based on clinical and laboratory evidence.
Main Results:
- Probiotic use was associated with a significantly decreased chance of VAP (adjusted OR = 0.29; 95% CI: 0.09-0.95).
- Probiotic recipients showed a significantly lower incidence of diarrhea compared to the placebo group (adjusted OR = 0.09; 95% CI: 0.01-0.96).
Conclusions:
- Probiotic prophylaxis is effective in preventing VAP in mechanically ventilated children.
- Probiotics also demonstrate efficacy in reducing diarrhea incidence in this patient population.
- This suggests probiotics as a valuable tool for infection control in PICUs.
Purpose:
Ventilator-Associated Pneumonia (VAP) is one of the most common nosocomial infections in the Pediatric Intensive Care Unit (PICU). Using new strategies to prevent nosocomial infections is crucial to avoid antibiotic resistance. One of these strategies is the utilization of probiotics. This study aims to investigate the efficacy of probiotic prophylaxis in preventing VAP in mechanically ventilated children.
Method:
This study was a randomized, double-blind clinical trial. The study included 72 children under 12 years of age under mechanical ventilation for more than 48 h in the Mofid Children's Hospital. Patients were randomly divided into Limosilactobacillus reuteri DSM 17938 probiotic recipients (n = 38) and placebo groups (n = 34). In addition to the standard treatment, both groups received a sachet containing probiotics or a placebo twice a day. Children were screened for VAP based on clinical and laboratory evidence.
Results:
The mean age of children in the intervention and placebo groups was 4.60 ± 4.84 and 3.38 ± 3.49 years, respectively. After adjusting the other variables, it was observed that chance of VAP among probiotics compared to the placebo group was significantly decreased (OR adjusted = 0.29; 95% CI: 0.09-0.95). Also, probiotic was associated with a significantly lower chance of diarrhea than the placebo group (OR adjusted = 0.09; 95% CI: 0.01-0.96).
Conclusion:
Probiotic utilization is effective in preventing the incidence of VAP and diarrhea in children under mechanical ventilation in the PICU.
