Summary
Malnourished infants show impaired cellular immunity, impacting their ability to fight infections. Transferrin levels effectively assess nutritional status and immune potential in these infants.
Area of Science:
- Pediatric Nutrition
- Immunology
- Infectious Diseases
Background:
- Malnutrition significantly impacts child health, particularly immune function.
- Understanding the interplay between nutrition and immunity is crucial for infant health.
- Cellular immunity plays a vital role in defending against infections.
Purpose of the Study:
- To investigate the relationship between malnutrition and cellular immunity in infants.
- To assess immune responses in malnourished versus healthy infants aged 3-18 months.
- To evaluate specific immune markers and their correlation with nutritional status.
Main Methods:
- Nutritional status assessed via dietary intake, anthropometry, and serum transferrin levels.
- Cellular immunity evaluated using skin tests (tuberculin, monilia, P.H.A., DNCB) and lymphocyte subset analysis.
- Peripheral lymphocyte counts and T-cell percentages were determined.
Main Results:
- Malnourished infants exhibited a deficiency in cellular immunity.
- Frequent non-response to antigens and weak sensitization to D.N.C.B. were observed.
- Some infants showed a reduced percentage of spontaneous T-cell rosettes.
Conclusions:
- Malnutrition leads to significant cellular immune deficits in infants.
- Transferrin levels are valuable for assessing nutritional status, guiding iron therapy, and predicting prognosis.
- Addressing malnutrition is essential for restoring immune function and improving health outcomes.
