Insights

This case study highlights zinc deficiency in a premature infant presenting with an acrodermatitis enteropathica-like rash. Oral zinc supplementation effectively resolved the skin condition, demonstrating its critical role in infant nutrition.

Area of Science:

  • Pediatrics
  • Dermatology
  • Nutritional Science

Background:

  • Premature infants often experience negative zinc balance due to insufficient stores and high metabolic demands.
  • Zinc deficiency can manifest with dermatological symptoms resembling acrodermatitis enteropathica.

Observation:

  • A 5-month-old male infant, born at 27 weeks gestation, developed a skin eruption at two months of age.
  • The infant received fortified breast milk, yet presented with low serum zinc levels.
  • Maternal serum and breast milk zinc concentrations were within normal limits.

Findings:

  • Oral zinc supplementation led to complete resolution of the skin eruption within three weeks.
  • The infant remained symptom-free for 22 months after treatment discontinuation, with no relapse.
  • This case underscores symptomatic zinc deficiency in premature infants despite adequate maternal zinc and milk fortification.

Implications:

  • Highlights the importance of monitoring zinc levels in premature infants, even with fortified nutrition.
  • Suggests that standard fortification may not always meet the high zinc requirements of extremely preterm infants.
  • Emphasizes the efficacy of oral zinc therapy for zinc deficiency-related dermatoses in neonates.

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,...

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...
Transcytosis of IgG01:15

Transcytosis of IgG

Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...
