The childhood arthritis radiographic score of the hip: the proposal cut-off value using cluster analysis.

BACKGROUND: Juvenile idiopathic arthritis (JIA) is a chronic rheumatic disease that affects children. It is crucial to detect and treat hip involvement in JIA early to prevent functional impairment and reduced quality of life. The Childhood Arthritis Radiographic Score of the Hip (CARSH) is a validated radiographic scoring system used to assess hip involvement in JIA. In this study, we aimed to determine cut-off values for CARSH scores using cluster analysis. METHODS: The study was conducted as a cross-sectional analysis and included JIA patients with hip involvement who underwent a pelvic radiograph. The same pelvic radiograph was interpreted by two experienced pediatric rheumatologists at baseline and after 3 weeks by both readers for reliability. The CARSH scores were calculated for each hip four times (twice by each reader). For the 50 hips, a total of 200 interpretations of the CARSH score were obtained. Model-based clustering was employed to identify distinct groups of CARSH score interpretations and characterize the phenotype of each cluster. RESULTS: Twenty-five children with hip involvement were included. The mean age was 13.9 ± 4.6 years. JIA subtypes were as follows: ERA in 64%, oligoarthritis in 16%, psoriatic arthritis in 12%, polyarthritis RF + in 4%, and RF - in 4% of patients. For the 200 hip interpretations, three clusters based on the level of the CARSH were identified by model-based clustering. Cluster 1 consisted of 17 CARSH score interpretations with a median score of 7 ± 3 (ranging from 1 to 15). This group primarily comprised patients with enthesitis-related arthritis (ERA) and psoriatic arthritis. Patients in cluster 1 were generally older, experienced longer diagnostic delays, and had a longer disease duration compared to the other clusters. Cluster 2 exhibited a moderate CARSH score, with an average score of 4 ± 3 (1 to 15). Patients in this group had significantly higher body weight compared to the other clusters. Cluster 3 represented the group with the least severe hip involvement, characterized by CARSH scores of 2 ± 1 (ranging from 0 to 9). This cluster had a higher proportion of male patients and higher C-reactive protein (CRP) levels than the other clusters. Regarding the individual items of the CARSH score, cluster 1 showed higher percentages of hip radiograph abnormalities such as joint space narrowing, erosions, growth abnormalities, and subchondral cysts. Cluster 2 was characterized by a high rate of acetabular sclerosis, with little to no abnormalities in other CARSH score items. Cluster 3 was the only group that exhibited hip subluxation, with minimal abnormalities in the other score items. In conclusion, this study identified three distinct groups of CARSH scores, representing varying levels of severity in hip involvement in JIA. These findings provide valuable insights for clinicians in assessing and managing JIA patients with hip involvement, enabling tailored treatment strategies based on the severity of the condition. Key Points • While a Childhood Arthritis Radiographic Score of the Hip (CARSH) is a valid and reliable tool in hip-related juvenile idiopathic arthritis, its use is limited in daily practice due to the lack of available cut-off values. • The cluster analysis defined three clusters based on the CARSH levels. • Cluster 1 exhibited the highest score with more damage and disability. Cluster 2 involved a moderate score and more overweight patients. Cluster 3 included the least level of the score but with an active disease parameter.

Assessment of self-esteem and community integration in spondyloarthritis / Evaluación de la autoestima y la integración comunitaria en la espondiloartritis

Introduction: The aim of this study was to identify the associated factors with lower self-esteem and restriction in community reintegration in SpA patients. Methods: This study was a cross-sectional study including SpA patients (ASAS criteria) aged 18–50 years. The level of self-esteem was assessed using the Rosenberg Self-Esteem Scale (RSES). The Reintegration to Normal Living Index (RNLI) evaluated the degree of reintegration to normal social activities. Anxiety, depression, and fibromyalgia were screened by the Hospital Anxiety and Depression Scale (HADS)-A, HADS-D, and FiRST, respectively. Statistical analysis was performed. Results: A total of 72 patients were enrolled (sex-ratio=1.88), with median (IQR) age of 39 years (28.25–46). Median (IQR) disease duration was 10 (6–14) years. Median (IQR) BASDAI and ASDAS were 3 (2.1–4.7) and 2.7 (1.9–3.48), respectively. Anxiety symptoms were screened in 10% of SpA patients, depression in 11%; and fibromyalgia in 10%. Median (IQR) RSES and RNLI scores were 30 (23.25–34), and 83 (53.25–93.25), respectively. Multivariate regression analysis identified the domain (work) of pain interference, VAS pain, HAD anxiety, PGA, marital status, and morning stiffness as factors associated with lower self-esteem. Restriction in the reintegration community was predicted by the presence of IBD, VAS pain, FIRST, deformity, enjoyment of life, and HAD depression. Conclusion: Pain intensity and interference, deformities, extra-articular manifestations, and deterioration of mental health were associated with low self-esteem and severe restriction in community reintegration among patients with SpA rather than inflammatory parameters.(AU)

Introducción: El objetivo de este estudio fue identificar el factor asociado a la baja autoestima y la restricción en la reintegración comunitaria en pacientes con espondiloartritis (EspA). Métodos: Este estudio fue un estudio transversal llevado a cabo incluyendo a pacientes con EspA (criterios ASAS) de entre 18 y 50 años de edad. El nivel de autoestima se evaluó mediante la Rosenberg Self-Esteem Scale (RSES). El Reintegration to Normal Living Index (RNLI) evaluó el grado de reintegración a las actividades sociales normales. La ansiedad, la depresión y la fibromialgia se evaluaron mediante la Hospital Anxiety and Depression Scale (HADS)-A, HADS-D y FIRST, respectivamente. Se realizó un análisis estadístico. Resultados: Se inscribieron 72 pacientes (razón por sexo: 1,88), con una mediana (IQR) de edad de 39 años (28,25-46). La IQR de la duración de la enfermedad fue de 10 (6-14) años. La IQR de BASDAI y ASDAS fue de 3 (2,1-4,7) y 2,7 (1,9-3,48), respectivamente. Se detectaron síntomas de ansiedad en el 10% de los pacientes con EspA, depresión en el 11% y fibromialgia en el 10%. La IQR de las puntuaciones RSES y RNLI fue de 30 (23,25-34) y 83 (53,25-93,25), respectivamente. El análisis de regresión multivariante identificó el dominio (trabajo) de la interferencia del dolor, el dolor VAS, la ansiedad HAD, la PGA, el estado civil y la rigidez matinal como factores asociados a una menor autoestima. La restricción en la comunidad de reintegración se predijo por la presencia de EII, el dolor VAS, la herramienta FIRST, la deformidad, el disfrute de la vida y la depresión HAD. Conclusiones: La intensidad y la interferencia del dolor, las deformidades, las manifestaciones extra-articulares y el deterioro de la salud mental se asociaron a una baja autoestima y de una severa restricción en la reintegración a la comunidad entre los pacientes con EspA más que los parámetros inflamatorios.(AU)
