Subclinical synovitis impact on the progression of lupus joint disease: A 10-year longitudinal multicenter study.

OBJECTIVE: To determine the effect of subclinical synovitis on the progression of joint disease in a cohort of patients with systemic lupus erythematosus over a mean follow-up of 10 years. METHODS: A longitudinal follow-up of 96 patients diagnosed with lupus was performed. All patients were considered clinically free of joint disease or with minimal joint impairment at baseline and were studied through ultrasound study of their dominant hand to assess the prevalence of subclinical synovitis. Now, over 10 years after we contacted them and reviewed their evolution to determine the impact of had or had not been diagnosed with subclinical synovitis in their current joint condition. RESULTS: Thirty-one of the 91 reached patients developed clinical progression in their joint manifestations (at least one ordinal degree of worsening). Of these, 23 (74,9%) had demonstrated subclinical synovitis at baseline. In the group of patients who did not progress clinically, 46 (76,6%) did not have this finding at the start of follow-up (p < .01, OR 9,44 95%CI 3,46-25,74). The patients in whom clinical progression was demonstrated had worse combined ultrasound scores than the rest of the patients: 6,41 SD 1,45 vs. 1,15 SD 0,97 (p < .01). CONCLUSIONS: The finding of subclinical synovitis in patients with systemic lupus erythematosus is associated with the development of joint disease progression both clinically and ultrasonographically.

Ultrasound changes following controlled mechanical stress in synovial tissue in the hands of healthy individuals.

OBJECTIVE: The physiological response of the synovium to acute mechanical stress has not been extensively studied. This response is interesting in terms of the morphological changes it can cause as any such changes should be taken into account during ultrasound examinations. The purpose of this study was to assess the extent of changes in ultrasound images of the synovial joint in the hands of healthy individuals after controlled mechanical stress. METHOD: We included 110 healthy volunteers on whom we carried out two ultrasound examinations of the non-dominant hand: one at baseline and the other after controlled handgrip exercise at 70% of the maximum voluntary contraction. RESULTS: The synovitis scores at baseline and after exercise were 0.472±0.798 and 0.772±1.162 t(109)=-3.791, respectively; p < 0.001. We observed no tenosynovitis in 88.2% of the participants at baseline, while after exercise the percentage fell to 70.9%; x2 (1, N=110) =10.0851, p = 0.0014. CONCLUSION: We conclude that synovitis and tenosynovitis are inducible by physical exercise and are detectable on ultrasound. This should be taken into account during ultrasound examinations for suspicion or follow-up of inflammatory rheumatism.

Delay and diagnostic pathway of patients with psoriatic arthritis in Spain.

INTRODUCTION AND OBJECTIVES: Delayed diagnosis results in a worse prognosis in patients with psoriatic arthritis. Our objective is to determine the diagnostic delay, the specialties consulted and the referral points of patients with psoriatic arthritis in our environment. PATIENTS AND METHODS: We distributed a survey to members of the Spanish association Acción Psoriasis inquiring about the objectives of the study. RESULTS: A total of 503 surveys were analysed. The diagnostic delay was 4.01 ±â€¯1.42 years. The proportion of patients who had consulted, before diagnosis, primary care was 79.9%, traumatology 33.8% and the emergency department was 30.2%. The proportion of referrals that eventually led to diagnosis came from primary care in 29.3% of cases, traumatology 15.8% and the emergency department 3.5%. DISCUSSION AND CONCLUSIONS: The delay in diagnosis far outweighs other European results. Emergency departments are an important transit point for these patients, but the proportion of referrals is very low. We believe that focusing on the importance of early diagnosis in this particular medical sector could resolve a large part of diagnostic delay.

Retraso y recorrido diagnóstico de pacientes con artritis psoriásica en España / Delay and Diagnostic Pathway of Patients with Psoriatic Arthritis in Spain

Introducción y objetivos: El retraso diagnóstico condiciona un peor pronóstico en pacientes con artritis psoriásica. Nuestro objetivo es determinar el tiempo de retraso diagnóstico, las especialidades consultadas y los puntos de derivación de pacientes con artritis psoriásica en nuestro medio. Pacientes y métodos: Distribuimos una encuesta entre los miembros de la asociación española Acción Psoriasis indagando sobre los objetivos del estudio. Resultados: Se analizaron 503 encuestas. El tiempo de retraso diagnóstico fue de 4,01±1,42 años. La proporción de pacientes que habían consultado, antes del diagnóstico, con atención primaria fue del 79,9%, con traumatología, del 33,8% y por urgencias, del 30,2%. La proporción de derivaciones que finalmente condujeron al diagnóstico provinieron de atención primaria en el 29,3% de los casos, de traumatología en el 15,8% y de urgencias en el 3,5%. Discusión y conclusiones: El retraso diagnóstico detectado supera extensamente otros resultados europeos. Los servicios de urgencias ocupan un lugar importante de tránsito de estos pacientes, sin embargo, la proporción de derivaciones es muy bajo. Entendemos que incidir en este gremio médico en particular sobre la importancia del diagnóstico precoz podría resolver gran parte del retraso diagnóstico.(AU)

Influence of smoking and obesity on treatment response in patients with axial spondyloarthritis: a systematic literature review.

To assess whether smoking and obesity are predictors of poor treatment response in patients with axial spondyloarthritis (axSpA). A systematic literature review was performed by searching in MEDLINE and EMBASE up to June 2019 with a strategy based on the PICO approach: Population: patients with axSpA; Intervention or exposure: smoking or obesity; Comparison: non-smokers (for smoking) and normal-weight individuals (for obesity); and Outcome: any response criteria currently validated for axSpA. The 2009 Oxford Centre for Evidence-based Medicine levels were used for assessing the studies quality. Out of 1873 references retrieved, 46 studies were selected for full-text review and 12 for data extraction: six stratified patients by smoking and six by obesity. All were longitudinal observational studies, except one, which was cross-sectional. Overall, these studies included 5291 patients (3917 for smoking and 1333 for obesity), and all these patients were on anti-tumor necrosis factor (anti-TNF) therapy. The quality of evidence was graded as level 2b except that from the cross-sectional study which was graded level 4. For smoking, the evidence found is inconsistent: two studies finding negative effects in response to anti-TNF while the other four found no differences in clinical response to this therapy. Regarding obesity, the evidence is more consistent: five of the six studies describing a negative influence in response to anti-TNF. According to the scientific evidence in patients with axSpA, obesity is associated with a more unsatisfactory response to anti-TNF therapy. A poorer response in smokers has yet to be demonstrated. Key Points • Identifying predictors of treatment response in axSpA, especially those that are modifiable, is relevant. • Obesity increases the risk of poorer response to anti-TNF agents in patients with axSpA. • Scientific evidence for smoking habit as a predictor of treatment response in axSpA is inconclusive.

Relationship between anthropometric variables and the cross-sectional area of the median nerve by ultrasound assessment in healthy subjects.

OBJECTIVE: Ultrasound study of the wrist in patients with suspected entrapment syndrome has severe limitations due to the variability of what is considered normal for the cross-sectional area of the median nerve and where to proceed to measure it. We aim to determine the extent to which different anthropometric variables influence the median nerve area in subjects without carpal tunnel syndrome. METHODS: We conducted an observational study based on a multivariate linear regression analysis using as a dependent variable the area of the median nerve cut at two specific points in the wrist of healthy subjects. The independent variables were sex, age, height, weight, body mass index, finger flexor strength, and carpal circumference. MAJOR RESULTS: The measurements of the median nerve cross-sectional area were normalized using a quadratic fixing procedure. Of all the variables included in the linear regression analysis, only carpal circumference and sex (0: female, 1: male) contributed significantly in the final model using the wrist crease as the measurement point (Constant B=-209.45, carpal circumference coefficient=21.07, sex coefficient 10.87). At four centimeters distal to the carpal fold, the model included the same variables (Constant B=-221.84, carpal circumference coefficient=24.01, and sex coefficient=11.41). CONCLUSION: Both the wrist circumference and the sex are variables that should be considered to determine cut-off points of normality in future validation studies about the cross-sectional area of the median nerve.
