Nutrient intake and nutritional status in children with juvenile chronic arthritis

Area of Science:

• Pediatric Rheumatology
• Nutritional Science
• Clinical Biochemistry

Background:

• Juvenile chronic arthritis (JCA) is a significant condition affecting children's health.
• Nutritional status is crucial for managing chronic inflammatory diseases like JCA.
• Previous research indicates potential links between JCA and altered nutrient profiles.

Purpose of the Study:

• To assess nutrient intake and nutritional status in children with JCA.
• To compare nutritional parameters between JCA subtypes and healthy controls.
• To investigate the relationship between nutritional status and disease activity markers.

Main Methods:

• Cross-sectional study comparing 15 children with JCA and 17 healthy controls.
• Assessment of anthropometric measurements, including weight and upper arm muscle area (UAMA).
• Analysis of nutrient intake, serum concentrations of hemoglobin, iron, zinc, and copper, and erythrocyte sedimentation rate (ESR).

Main Results:

• Children with polyarticular JCA had reduced weight and UAMA compared to controls.
• Polyarticular JCA patients showed lower hemoglobin, serum iron, and serum zinc levels.
• Increased serum copper and positive correlation with ESR were observed in polyarticular JCA patients.
• Reduced dietary calcium intake was noted in the polyarticular JCA group.
• Impaired nutritional status persisted despite increased energy and protein intake in polyarticular JCA.

Conclusions:

• Polyarticular JCA is associated with significant nutritional deficits, including reduced muscle mass and specific micronutrient deficiencies.
• Inflammatory processes, indicated by ESR, correlate with altered iron, zinc, and copper metabolism.
• Despite increased caloric and protein intake, children with polyarticular JCA exhibit poor nutritional status and reduced calcium intake, highlighting the need for targeted nutritional interventions.
