[Changes in the hepatobiliary system in juvenile rheumatoid arthritis]

Area of Science:

• Pediatrics
• Rheumatology
• Medical Imaging

Background:

• Juvenile rheumatoid arthritis (JRA) can affect multiple organ systems.
• Hepatobiliary system involvement is a potential complication of JRA.
• Early detection of complications is crucial for patient management.

Purpose of the Study:

• To evaluate the effectiveness of echography in assessing hepatobiliary system affection in children with JRA.
• To correlate echographic findings with clinical and laboratory data in JRA patients.
• To determine the diagnostic value of echography for JRA-related complications, especially secondary amyloidosis.

Main Methods:

• Echographic (ultrasound) examinations were performed on 42 children aged 4-15 years diagnosed with JRA.
• Patients were categorized into three groups based on disease presentation.
• Findings were compared with clinical manifestations, laboratory results, disease form, and treatment characteristics.

Main Results:

• Hepatobiliary system abnormalities were detected in 60% of JRA patients.
• Abnormalities were more prevalent in the articular-visceral form (78.5%) compared to the articular form.
• 100% of patients with JRA complicated by secondary amyloidosis showed significant echographic changes.
• A correlation was established between echographic signs and the nature of JRA lesions.

Conclusions:

• Echography is a highly informative imaging modality for evaluating hepatobiliary system involvement in pediatric JRA.
• The method demonstrates particular efficacy in diagnosing secondary amyloidosis associated with JRA.
• Ultrasound findings correlate with disease severity and specific JRA manifestations.
