Probiotic Studies in Neonatal Mice Using Gavage
Published on: January 27, 2019
Summary
Probiotics offer modest benefits for childhood gastroenteritis and antibiotic-associated diarrhea. More research is needed for other conditions and for prebiotics in children, with safety considerations for vulnerable infants.
Area of Science:
- Pediatric Nutrition
- Microbiome Research
- Clinical Therapeutics
Background:
- Probiotics are live microorganisms influencing host microflora.
- Prebiotics are non-digestible ingredients promoting beneficial bacteria.
- Human milk is a natural source of prebiotics.
Purpose of the Study:
- To review the health benefits of probiotics and prebiotics in children.
- To assess the efficacy and safety of these supplements in pediatric populations.
- To identify areas requiring further clinical research.
Main Methods:
- Review of randomized clinical trials (RCTs) on probiotic and prebiotic use in children.
- Analysis of existing literature on health outcomes associated with these interventions.
- Evaluation of safety data for specific pediatric populations.
Main Results:
- Probiotics show modest efficacy in treating viral gastroenteritis and preventing antibiotic-associated diarrhea in healthy children.
- Evidence suggests probiotics may prevent necrotizing enterocolitis in very low birth weight infants, but requires more study.
- Preliminary data on probiotics for H. pylori, IBS, IBD, and atopy are encouraging but need confirmation.
- Probiotics are not proven for cancer treatment or Crohn's disease in children.
- Safety concerns exist for immunocompromised or seriously ill children.
- Limited RCTs on prebiotics in children suggest potential long-term benefits for atopic eczema and infections.
Conclusions:
- Probiotics are beneficial for specific pediatric conditions like acute gastroenteritis and antibiotic-associated diarrhea.
- Further well-designed studies are essential to confirm benefits and safety of probiotics and prebiotics in children.
- Targeted research is needed for vulnerable pediatric groups and for prebiotics' long-term effects.

01:23Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption
Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
01:22Probiotics
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...
01:21Microbiota Modulation by Antibiotics
Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
01:24Pharmacokinetics in Pediatric Patients: Drug Metabolism
In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses a challenge in...
01:26Pharmacokinetics in Pediatric Patients: Drug Excretion
In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...
01:17Pharmacokinetics in Pediatric Patients: Drug Distribution
Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight, compared...
