| الوصف: | Background Active disease in chronic rheumatic diseases in adults seems to be associated with overweight and obesity [1]. Juvenile Idiopathic Arthritis (JIA) is the most frequent rheumatic disease in children. The relationship between body mass index (BMI) and disease activity in JIA patients is less studied. Objective To determine the link between BMI and disease activity in JIA patients. Methods We conducted a cross-sectional study including 35 JIA patients meeting the International League of Associations for Rheumatology (ILAR) 2001 criteria. For each patient, we collected the following data: age, age at the onset of JIA, disease duration, patient global assessment (PGA), visual analogic scale (VAS), tender joint count (TJC), swollen joint count (SJC), disease activity using the Juvenile Arthritis Disease Activity score (JADAS), and therapeutic management. The weight and height were measured for each patient. The BMI was calculated and interpreted according to the World Health Organization classification. We also measured C-reactive protein (CRP) and Erythrocyte sedimentation rate (ERS) level. Results We included 15 boys and 20 girls. The mean age was 12.2 ± 3.61 years. The mean age at the onset of the disease was 8.65 ± 3.83 years. The mean disease duration was 4.1 ± 3.29 years. The mean PGA and the mean VAS were 3.4 ± 3.02 and 3.37 ± 2.92, respectively. The mean TJC and the mean SJC were 1.48 ± 1.69 and 0.61 ± 0.77, respectively. The mean CRP and ESR were 7.51 ± 11.85 mg/l and 18.88 ± 15.53 mm, respectively. The mean JADAS was 7.58 ± 6.3. Twenty-four patients were under non-steroidal anti-inflammatory drugs (69%), 10 patients were under methotrexate (34%), and 5 patients were under TNFα inhibitor (14%). The mean BMI was 19.94 ± 5.46 kg/m². Fourteen patients were underweight (40%), 15 patients had a BMI in the normal range (43%), 4 patients were overweight (11%), and 2 patients were obese (6%). Underweight patients had higher PGA, higher CRP level, higher tender joint count (TJC), and higher JADAS compared with overweight and obese patients, but without significant difference (PGA: 2.97 ± 2.6 vs 2 ± 1.89, p = 0.4; CRP: 7.54 ± 15.09 vs 4.25 ± 4.19 mg/l, p = 0.6; TJC: 1.7 ± 1.56 vs 1 ± 0.8, p = 0.3, and JADAS: 6.3 ± 6.18 vs 2.98 ± 2.24, p = 0.1). No correlations were found between BMI and the following parameters: TJC, SJC, EGP, CRP, ESR, and JADAS. Conclusion Data about associations between underweight, obesity, and disease activity in JIA are conflicting. Some authors suggested that active disease is associated with adiposity [2]. Others showed that underweight patients had higher disease activity [3]. Although there was no significant difference, our study is consistent with Neto et al. study. Indeed, active disease seems to affect the child’s appetite and weight gain leading to cachexia [3]. Other studies are needed to confirm these results. References 1.
