[Malnutrition and immunodeficiency in children]

Area of Science:

• Nutritional science
• Immunology
• Infectious diseases

Context:

• The interplay between nutrition, immunity, and infection is a complex biological system.
• Malnutrition significantly impairs the body's defense mechanisms.

Purpose:

• To highlight the critical role of nutrition in immune function.
• To emphasize the need for nutritional intervention in combating infections.

Summary:

• Malnutrition negatively impacts innate immunity, cellular immunity, and humoral immunity.
• All essential nutrients, including macronutrients, micronutrients (trace elements), and vitamins, are implicated.
• Adequate nutritional status is essential for preventing and managing infections.

Impact:

• Restoring and maintaining optimal nutritional status is imperative for child health.
• Interventions can break the detrimental cycle of malnutrition and recurrent infections in pediatric populations.
