Background Juvenile idiopathic arthritis (JIA) is the most common inflammatory arthritis in children. Chronic inflammation, as well as the various treatments used during JIA increase the risk of occurrence of osteoporosis (OP) and fractures. Objectives The objective of this work was to determine the frequency of OP in JIA and to investigate the factors associated with its occurrence. Methods This was a retrospective study including adults with long-standing JIA according to the International League of Associations for Rheumatology (ILAR) criteria over a period of 28 years (1994–2022). We collected sociodemographic and anthropometric parameters, clinical data, results of biological assessments, bone densitometry results and data on prescribed therapies. We compared these variables according to the bone densitometry profile to assess the factors associated with OP in JIA. Results There were 29 patients (17 females and 12 males), the mean age was 35.69 ± 11.72 [18–61] years. The mean age of disease onset was 11.10 ± 4.25 [2–16] years. The average diagnostic delay was 52.96 ± 95.97 [0–336] months. The average disease duration was 24.48 ± 12.76 [1–47] years. Three patients were smokers. The mean BMI was 21.20 ± 4.88 [14.17–27.55] kg/m2, and 4 patients had a BMI ≥ 25 kg/m². The polyarticular form was the most frequent, noted in 55.2% of cases (n = 16). NSAIDs, corticosteroids and methotrexate were prescribed in 62.1%, 69% and 79.3% of cases respectively. OP was found in 24.1% of cases (n = 7). Mean T-score values at the lumbar and femoral sites were −2.20 ± 1.22 SD and −2.31 ± 0.97 SD, respectively. Six patients suffered at least one fracture. Patients with OP had lower BMI than patients with normal bone density (17.02 ± 2.46 vs 23.91 ± 5.42; p = 0.046). Furthermore, absence of rheumatoid factor was associated with OP in our study (83.3% vs 16.7%; p = 0.008). On the other hand, the following parameters were not associated with the occurrence of OP in our study: age, gender, smoking, age at onset and duration of progression of JIA, BMI, extra-articular manifestations, CRP, antinuclear antibodies, ACPA and erosive character. Regarding the treatment received (NSAIDs, corticosteroids and methotrexate), no difference was found between patients. Conclusion Osteoporosis in JIA is common and has a prognostic impact. It must be systematically screened throughout the follow-up. In our study, OP was associated with the absence of rheumatoid factor and was more frequent in patients with low BMI.
Background Juvenile idiopathic arthritis (JIA) is a pediatric rheumatic disease with several subgroups. The hip is frequently affected. The frequency of this involvement can reach 50% especially in the severe and destructive forms. Arthroplasty may be indicated in advanced cases. Objectives To assess the frequency and associated factors with hip involvement in (JIA). Methods We conducted a retrospective study including adults with long-standing JIA according to the International League of Associations for Rheumatology (ILAR) criteria over a period of 28 years (1994–2022). Demographic, clinical, biological, and radiographic data were collected. These parameters were compared according to the presence or absence of hip involvement. Results A total of 29 Patients were enrolled (12 men and 17 women), the mean age was 35.69 ± 11.72 [18–61] years. The mean age of disease onset was 11.10 ± 4.25 [2–16] years. The average diagnostic delay was 52.96 ± 95.97 [0–336] months. The average disease duration was 24.48 ± 12.76 [1–47] years. Sixteen patients had a polyarticular form. Mean CRP values were 42.74 ± 63.37 [2–218] mg/l, a biological inflammatory syndrome was present in 19 cases. Rheumatoid factor, ACPA and anti-nuclear antibodies were observed in 12, 7 and 5 cases respectively. At least one extra-articular manifestation was noted in 16 cases. Hip involvement was noted in 14 patients (48.3%). It was bilateral in 64.3% of cases (n = 9). Twenty-three hips were affected in total (56.9%). Hip involvement was diagnosed 14.5 ± 9.37 [1–28] years after disease onset. Arthroplasty was performed on 10 hips with a delay of 201.60 ± 104.75 [108–348] months between diagnosis of JIA and surgery. Hip involvement was associated with male gender in our study (75% vs 29.4%; p = 0.016). On the other hand, our study showed that age, age at onset, diagnostic delay, symptoms duration, smoking, BMI, extra-articular manifestations, CRP, rheumatoid factor, antinuclear antibodies, ACPA and erosive character were not associated with hip involvement. Conclusion Our study showed that hip involvement is common in JIA, mainly in male patients. It usually occurs late in the disease course. Since hip involvement is a cause of disability and functional impairment, it should be assessed regularly.
Background Juvenile idiopathic arthritis (JIA) is a chronic rheumatic disease seen in children below 16 years of age. However, it may persist into adulthood. The damage caused by the disease can influence the sex life and fertility of adults with long-standing JIA. Objectives To study the fertility of patients with JIA. Methods We conducted a retrospective study including adults with long-standing JIA according to the International League of Associations for Rheumatology (ILAR) criteria. A detailed questionnaire was completed for each participant by interviewing them as well as by information obtained from their medical records. We identified among the adult patients, those who are married, their age at marriage, the number of gestation and parity, the age of the first child, miscarriages, and occurrence of menopause. Results A total of 29 Patients were enrolled, the M/F sex ratio was 0.71. The mean age was 35.69 ± 11.72 [18–61] years. The mean age of disease onset was 11.10 ± 4.25 [2–16] years. The average disease duration was 24.48 ± 12.76 [1–47] years. The mean BMI was 21.20 ± 4.89 [14.17–27.55] kg/m², 36.9% of patient had a BMI ≥ 25 kg/m². Fourteen patients had hip involvement. Seven patients (6 women, 1 man) were married (24%). The mean age at marriage was 23.75 ± 7.5 [20–35] years. The mean delay between disease onset and marriage was 10 ± 6.68 [6–20] years. Six patient had children, the mean number of gestation and parity were 2.56 ± 2.88 [0–6] and 2 ± 2.29 [0–6] respectively. Miscarriage was noted in 2 patients. Menopause was observed in 3 patients, the mean age at menopause was 46.67 ± 1.53 [45–48] years. Conclusion Most of our patients were not married. This reflects the significant impact of the disease on the social and sexual life of JIA patients at adulthood.
