Insights
Cow's milk allergy (CMA) affects 2-7% of infants. This study highlights two preterm twins with CMA presenting with different gastrointestinal issues, including NEC-like symptoms, emphasizing early diagnosis and varied clinical presentations.
Area of Science:
- Pediatrics
- Allergy and Immunology
- Neonatology
Background:
- Cow's milk protein allergy (CMA) incidence is rising in newborns, including premature infants.
- Adverse reactions to cow's milk affect 2-7% of infants within their first year.
- Early-onset CMA poses diagnostic challenges in the neonatal population.
Observation:
- Two cases of early-onset CMA in preterm twins are presented.
- One twin experienced recurrent proctocolitis, while the other had two necrotizing enterocolitis (NEC)-like episodes.
- Clinical presentations varied significantly between the twins despite the same underlying condition.
Findings:
- The cases illustrate diverse clinical manifestations of cow's milk protein allergy.
- Recurrent enterocolitis episodes were associated with increasing systemic eosinophilia.
- Symptoms clinically and radiologically mimicked NEC, complicating diagnosis.
Implications:
- Highlights the importance of considering CMA in preterm infants with gastrointestinal distress.
- Suggests eosinophilia as a potential marker for CMA in this population.
- Underscores the need for heightened awareness of varied CMA presentations mimicking surgical emergencies like NEC.
Abstract:
Adverse reactions to cow's milk in the first year of life occur in 2-7%. There is an increase in the incidence of cow's milk protein allergy (CMA) in newborn population including premature infants. We report two cases of CMA in preterm twins. The first one developed recurrent episodes of proctocolitis and the second one two necrotizing enterocolitis (NEC) -like episodes. Our cases demonstrate different clinical presentations of the same disease and add to literature the peculiarity of the early onset, the recurrence of episodes of enterocolitis associated with increasing systemic eosinophilia and episodes clinically and radiologically mimicking NEC.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
