Insights

Children in developing countries may not fully recover growth after diarrhea due to persistent intestinal damage. This study links small bowel mucosal abnormalities to impaired growth in Gambian infants, explaining significant growth faltering.

Area of Science:

  • Pediatrics
  • Gastroenterology
  • Global Health

Background:

  • Diarrhea is a major cause of childhood illness in developing countries.
  • Catch-up growth potential after illness is debated, with mucosal injury being a key factor.
  • Assessing intestinal integrity is crucial for understanding growth faltering.

Purpose of the Study:

  • To investigate the relationship between intestinal disease and growth performance in young children.
  • To determine if persistent intestinal abnormalities affect catch-up growth after diarrhea.
  • To quantify the contribution of long-term intestinal lesions to growth faltering.

Main Methods:

  • A longitudinal study involving 2-15 month old Gambian infants.
  • Regularly administered lactulose:mannitol permeability tests to assess intestinal integrity.
  • Continuous monitoring of infant growth rates over a mean period of 7.5 months.

Main Results:

  • Persistent abnormalities in the small bowel mucosa were identified in the study population.
  • A significant negative correlation was observed between intestinal mucosal abnormalities and infant growth.
  • Long-term intestinal lesions were found to explain up to 43% of observed growth faltering.

Conclusions:

  • Persistent small bowel mucosal lesions are prevalent in young Gambian children.
  • Intestinal integrity is a critical determinant of growth performance in this population.
  • Targeting intestinal health may be essential for improving child growth in developing countries.

Anatomy of the Intestines01:23

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the small...
Inborn Errors of Metabolism01:20

Inborn Errors of Metabolism

Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Pharmacokinetics 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...
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...
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,...
Intestinal Obstruction II: Pathophysiology01:07

Intestinal Obstruction II: Pathophysiology

Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...
