Insights

This study found that Lactobacillus rhamnosus Lcr35 (Lcr Restituo) significantly reduced necrotizing enterocolitis (NEC), mortality, and late-onset sepsis in very low-birth-weight infants. The probiotic was well-tolerated and improved feeding times.

Area of Science:

  • Neonatal Medicine
  • Microbiology
  • Pediatric Gastroenterology

Background:

  • Necrotizing enterocolitis (NEC) is a significant concern in very low-birth-weight infants.
  • Probiotics have shown promise in reducing NEC, but routine use remains debated.
  • A specific probiotic strain, Lactobacillus rhamnosus Lcr35 (Lcr Restituo), has been used as standard care in preterm infants since 2008.

Purpose of the Study:

  • To evaluate the efficacy and safety of Lactobacillus rhamnosus Lcr35 (Lcr Restituo) in reducing NEC and other morbidities in preterm infants.
  • To compare outcomes in a cohort of infants receiving probiotics with a historical control group.

Main Methods:

  • A cohort study comparing infants receiving Lactobacillus rhamnosus Lcr35 (Lcr Restituo) (2 × 10^8 colony-forming units/12 h) with a historical cohort.
  • Treatment was initiated early post-birth and continued up to 36 weeks' gestation.
  • Primary outcome was definite NEC; secondary outcomes included mortality, late-onset sepsis (LOS), cholestasis, isolated rectal bleeding (IRB), and time to full enteral feeding (FEF).

Main Results:

  • A total of 1130 infants were included; no adverse effects were reported.
  • The probiotic cohort (PC) showed significantly reduced rates of NEC (OR 0.20), mortality (OR 0.46), and LOS (OR 0.60).
  • Infants in the PC group achieved full enteral feeding (FEF) earlier, and isolated rectal bleeding (IRB) was significantly reduced with complete treatment.

Conclusions:

  • Lactobacillus rhamnosus Lcr35 (Lcr Restituo) administration was well-tolerated in preterm infants.
  • The probiotic was associated with lower rates of mortality and morbidities, including NEC, LOS, and IRB.
  • Results support the use of this specific probiotic strain to improve outcomes in very low-birth-weight infants.

Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Probiotics01:22

Probiotics

Probiotics are live, non-pathogenic microorganisms that confer health benefits by modulating the gut microbiota. The human gastrointestinal tract harbors a complex microbial ecosystem, and the balance of this microbiota is crucial for digestive and systemic health. Among the most extensively studied and utilized probiotics are species formerly classified within the genera Lactobacillus and Bifidobacterium. These organisms not only naturally colonize the human gut but are also consumed through...
Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Bioavailability Study Design: Healthy Subjects Versus Patients

Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...
