Influence of acute respiratory infection on iron profile in severely malnourished children

Area of Science:

• Pediatric Nutrition
• Infectious Diseases
• Hematology

Background:

• Severe malnutrition in children (12-59 months) is a critical health issue.
• Acute respiratory infection (ARI) is a common comorbidity in malnourished children.
• Iron metabolism is crucial for immune function and overall health.

Purpose of the Study:

• To compare the iron profile of severely malnourished children with and without ARI to that of healthy children.
• To investigate the impact of ARI on specific iron parameters in malnourished children.

Main Methods:

• A comparative study involving 72 severely malnourished children (36 with ARI, 36 without) and 36 healthy controls.
• Measurement of serum iron, serum ferritin, total iron-binding capacity (TIBC), and transferrin saturation.
• Statistical analysis to compare iron profile parameters between groups.

Main Results:

• Severely malnourished children had significantly lower serum iron and TIBC than healthy children.
• Non-infected malnourished children had lower serum iron than healthy children but higher than those with ARI.
• Children with ARI had significantly higher serum ferritin levels compared to non-infected malnourished children, but lower than healthy children.
• Transferrin saturation was significantly reduced in both malnourished groups compared to healthy controls.

Conclusions:

• Acute respiratory infection significantly influences iron metabolism in severely malnourished children.
• ARI contributes to reduced serum iron, TIBC, and transferrin saturation.
• Elevated serum ferritin in ARI may indicate an acute phase response, though overall levels remain suboptimal.
