"Reuma-Check": Performance of a Comprehensive Fast-Track Program for the Diagnosis of Axial Spondyloarthritis in South America.

OBJECTIVES: The aim of this study was to evaluate the performance of a comprehensive diagnosis program called "Reuma-check" for the diagnosis of axial spondyloarthritis (SpA) in patients with low back pain (LBP). METHODS: This is a cross-sectional study. Patients with LBP aged 18 years or older were preselected, and those with at least 1 SpA feature completed the circuit. They were referred after 2 strategies: education for orthopedists and a campaign on social networks. All patients underwent a clinical evaluation, laboratory testing, and imaging (including human leukocyte antigen B27 evaluation and magnetic resonance imaging). The diagnosis of axial SpA was established by an expert rheumatologist opinion. Time from onset of symptoms to "Reuma-check," time from patient referral to admission of the checkup, and time from "Reuma-check" to diagnosis were evaluated. RESULTS: A total of 175 of 246 patients were included, most of them came from the social media campaign (55%). Seventy-five (43%) of 175 patients were diagnosed as axial SpA. The median time from referral (or self-referral) to access to the program was 1.3 months. The median time from symptoms onset to access to the program was 31.7 months, and the median time from the performance of "Reuma-check" to final diagnosis was 2 weeks. Features associated with a diagnosis of axial SpA were as follows: inflammatory LBP (odds ratio [OR], 6.64; 95% confidence interval [CI], 1.6-28), clinical enthesopathy (OR, 4.56; 95% CI, 1.1-18.4), positive human leukocyte antigen B27 (OR, 23.02; 95% CI, 3.5-58), and positive magnetic resonance imaging (OR, 14.34; 95% CI, 3.5-58). CONCLUSIONS: "Reuma-check" allowed a high frequency of axial SpA diagnosis and improved access to rapid diagnosis, shortening the time from referral to diagnosis with a shorter acquisition time for the ancillary studies. Patients with a final diagnosis of axial SpA presented distinctive features.

EULAR definition of "arthralgia suspicious for progression to rheumatoid arthritis" in a large cohort of patients included in a program for rapid diagnosis: role of auto-antibodies and ultrasound.

OBJECTIVES: To evaluate the performance of the European League Against Rheumatism (EULAR) definition of arthralgias suspicious for progression to RA in patients with hand arthralgias and to estimate the added value of both auto-antibodies and ultrasound (US) with power Doppler (PD). METHODS: Consecutive patients admitted for hand arthralgias to "Reuma-check" ® program were included. This program includes the following at baseline: clinical assessment, laboratory tests, US with PD of both hands, and radiography of both hands and feet. All patients were followed-up after baseline evaluation by their treating rheumatologists, and a definitive diagnosis of RA (ACR/EULAR 2010 criteria) was established or not. RESULTS: A total of 465 consecutive patients were included. During follow-up, 44 (9.4%) were diagnosed with RA. Mean of baseline EULAR features describing arthralgia suspicious for progression to RA was 4.1 in patients with final diagnosis of RA vs 2.3 in non-RA patients (p < 0.0001). The AUC for the EULAR defined features describing arthralgia suspicious for progression to RA for the final diagnosis of RA was 0.7827, while adding US with PD, rheumatoid factor (RF), and anti-cyclic citrullinated peptide antibodies (ACPA) data, the AUC was 0.9172 (p < 0.0001). In the multivariate regression logistic analysis, baseline features associated with a final diagnosis of RA were difficulty with making a fist, RF, ACPA, and US with PD. CONCLUSIONS: EULAR definition of arthralgia suspicious for progression to RA had an acceptable performance to predict the future development of RA and improves adding information of both RF, ACPA and US with PD data.Key Points• Clinically suspect arthralgia may trigger rheumatologists to monitor patients closely for an early diagnosis.• EULAR definition of arthralgia suspicious for progression to RA predicts future development of arthritis.• Auto-antibodies and ultrasound improve EULAR definition of arthralgia suspicious for progression to RA.

Factores asociados al desarrollo de secuelas en un grupo de pacientes con síndrome doloroso regional complejo tipo 1 (SUDECK) / Associated factors related to the development of sequels in a group of patients with complex regional pain syndrome type 1 (SUDECK)

Introducción: El Síndrome doloroso regional complejo tipo 1 (SDRC) o Sudeck se caracteriza por manifestarse con dolor, tumefacción, trastornos sensoriales, disfunción vasomotora autonómica, cambios tróficos en los tejidos y trastornos en la motilidad del área afectada. Pudiendo ocurrir en una o varias regiones articulares, sin repercusión sistémica y sin modificar parámetros inflamatorios. Objetivo: Estimar el porcentaje de pacientes que desarrollan secuelas en el seguimiento y los factores asociados. Materiales y Métodos: Estudio Prospectivo, observacional, se incluyeron pacientes mayores de 18 años con diagnostico de SDRC tipo 1 según criterios Budapest. Se consignaron variables demográficas, de las características de la enfermedad, tipo, tiempo y respuesta al tratamiento. Se definió secuelas según el registro de historias clinicas de el consultorio de riesgo de trabajo "alta con secuelas". Resultados: Se incluyeron 98 pacientes, de los cuales el 65,3 % eran mujeres, con una mediana de edad de 54 años (RIC: 45-61). El desarrollo de Secuelas (60%) se asoció con la, indicación precisa de rehabilitación (p 0,001). Conclusión: El 60 % de los pacientes desarrollaron secuelas en su seguimiento, las mismas se asociaron en forma independiente con la indicación de rehabilitación y en forma negativa con la buena respuesta al tratamiento.

Background/Purpose: complex regional pain syndrome (CRPS) is a form of chronic pain that usually affects an arm or a leg. CRPS typically develops after an injury, a surgery, a stroke or a heart attack. The pain is out of proportion to the severity of the initial injury. CRPS is uncommon, and its cause isn't clearly understood. Methods: To estimate the percentage of patients with CRPS who develop disability and its associated factors. Consecutive patients older than 18 years old whose met Budapest criteria for CRPS type 1 were included. Demographic variables, time of follow-up, main cause of the disease and location, time between trauma and starting treatment were recorded from the electronic clinical history (ECH). Previous immobilization, type were recorded. of treatment, response to it and clinical manifestations. Disability was defined when there was a change in work activity. Results: 98 patients were included with at least one year of follow up, 65.3% were women. The median age is 54 years (45-61). The prevalence of disability was 60%. We found a significant and independent association with indication of rehabilitation (OR: 4.3 CI: 1.3-14) and response to treatment (OR: 0.078 CI: 0.023-0, 2). Conclusion: 60% of the patients developed disability in their follow-up, they were associated independently with the indication of rehabilitation and in a negative way with a good response to treatment.
