Utility of applying a diagnostic algorithm in giant cell arteritis based on the level of clinical suspicion. / Utilidad de la aplicación de un algoritmo diagnóstico en la arteritis de células gigantes en función del grado de sospecha clínica.

INTRODUCTION: To reach the diagnosis of giant cell arteritis (GCA), signs, symptoms, laboratory tests, imaging findings, and occasionally anatomopathological results from temporal artery biopsy are evaluated. This study describes the results of an algorithm analysis based on clinical and ultrasound evaluation of patients with suspected GCA, highlighting its diagnostic utility by contrasting its use in different clinical suspicion scenarios. METHOD: Prospective multicenter study evaluating patients referred with suspected GCA through a preferential circuit (fast track), grouping them according to low or high clinical suspicion of GCA. Each of these scenarios is evaluated by biopsy and ultrasound for all patients, resulting in positive, indeterminate, or negative outcomes, yielding six possible groups. Potential areas of improvement are explored, emphasizing that, following a negative or indeterminate ultrasound, 18-FDG-PET-CT could be recommended. We analyze the results and application of a diagnostic algorithm, confirming its efficiency and applicability based on whether there is high or low clinical suspicion. RESULTS: Sixty-nine patients (41 in the high suspicion group and 28 in the low suspicion group). There were 41 new diagnoses of GCA: 35 in the high suspicion group and 6 in the low suspicion group. Using ultrasound alone, the initial algorithm has an overall diagnostic efficiency of 72.5%, which improves to 80.5% when including 18F-FDG-PET/CT. The negative predictive value of ultrasound in patients with low clinical suspicion is 84.6%, and the positive predictive value of ultrasound in patients with high suspicion is 100%, improving sensitivity from 57.1% to 80.8% with 18F-FDG-PET/CT in this scenario. Temporal artery biopsy was performed on all patients, with no differences in sensitivity or specificity compared to ultrasound. In cases where all three tests - ultrasound, biopsy, and 18F-FDG-PET/CT - are performed, sensitivity increases to 92.3% in patients with high clinical suspicion. CONCLUSION: In situations of high clinical suspicion, the algorithm provides sufficient information for the diagnosis of GCA if ultrasound is positive. A negative ultrasound is sufficient to rule out the diagnosis in the context of low clinical suspicion. 18-FDG-PET-CT may be useful in patients with high suspicion and negative or indeterminate ultrasound results.

Sesgos de género en la reumatología española: Percepciones y realidad / Gender biases in Spanish rheumatology: Perception and facts

Objetivo: Identificar percepciones en cuanto a sesgos de género en la reumatología española y cuantificar la implicación de ambos sexos en todos los ámbitos de la especialidad. Métodos: Se envió una encuesta a todos los miembros de la SER, sobre participación y percepción de sesgos y de la propia capacitación y se revisaron los datos reales de participación en órganos directivos, congresos, comités y de los servicios de reumatología españoles en los últimos cinco años. Resultados: La encuesta fue respondida por 95 personas, 4,8% de los miembros de la SER (14 hombres y 81 mujeres). No se detectaron diferencias por sexo en edad, nivel académico, puesto, centro de trabajo, reparto de tareas laborales y del ámbito familiar; tampoco en las invitaciones a puestos de poder en los cinco últimos años, ni en la percepción de capacidad para ocupar los distintos puestos de poder. Los hombres encuestados consideran con mayor frecuencia que actividades como la participación en un comité científico o dar una ponencia no dan poder. Un tercio de los participantes de ambos sexos considera que la SER debería revisar sus procesos con perspectiva de género y menos de un tercio cree que debe hacerse por cuotas. Tras revisar los datos de 2015 a 2020, los ratios hombre a mujer en las principales actividades de liderazgo en reumatología en España son: 1) juntas directivas de la SER 3:2 sin presidenta ni tesorera; 2) comités científicos de los congresos 2:1; 3) ponentes y moderadores: simposios satélites, 4:1; 4) editores jefes de revistas científicas 9:1; 5) puestos académicos global 1,7:1, catedráticos 9:1, profesores titulares 100% hombres y 6) jefes de servicio: 75% son hombres a pesar de representar 40% de reumatólogos en España. Conclusión: A pesar de un creciente número de mujeres en la reumatología española, estas no están suficientemente representadas en puestos de liderazgo, existiendo un sesgo de género no percibido.(AU)

Objective: To identify perceptions of gender bias in Spanish rheumatology and to quantify the involvement of both sexes in all areas of the specialty. Methods: A survey was sent to all members of the SER on participation and perception of biases and of their own competencies, and actual data on participation in governing bodies, congresses, committees, and Spanish rheumatology departments in the last 5 years were reviewed. Results: The survey was answered by 95 rheumatologist, 4.8% of SER members (14 men and 81 women), both groups being similar in terms of age, academic level, and position and work centre. No differences were detected in the distribution of work and non-work tasks between sexes, nor in invitations to positions of power in the last five years, nor in the perception of capacity to occupy the different positions of power, which was high for both sexes. Male respondents more frequently consider that activities such as participating in a scientific committee or giving a conference are not empowering. A third of both sexes consider that the SER should review its processes with a gender perspective but less than a third believe that this should be done by quotas. The reality of the last 5 years is that 1) there is a male to female ratio of 3:2 on SER boards of directors and in this period there has been no female president or treasurer; 2) in the scientific committees of the congresses men predominate (2:1) although slightly less in the local organizing committee; 3) there are more male speakers and moderators than women (very striking in satellite symposia, 4: 1); 4) 9 out of 10 editors-in-chief are men; 5) in academic positions there are 3 men for every 2 women, 9 to 1 in professorships or emeritus positions; although more women supervise residents; and 6) there are more women (60%) than men (40%) in Spanish rheumatology departments, although 75% of department chiefs are men. Conclusion: Although not perceived by either the men or the women...(AU)

CONCLUSION: Although not perceived by either the men or the women, there are biases in the involvement of women in important and leadership positions in the specialty.

Efficacy of secukinumab on dactylitis in patients with active psoriatic arthritis from the FUTURE 5 study.

OBJECTIVES: Dactylitis is an important clinical domain of psoriatic arthritis (PsA) associated with significant burden of disease and impaired function. Post-hoc analysis of the FUTURE 5 study was performed to evaluate the efficacy of secukinumab in patients with dactylitis at baseline over 2 years. METHODS: Randomised patients received secukinumab 300mg with loading dose (LD)/150mg LD/150mg without loading dose/placebo. Assessment of dactylitis was based on Leeds Dactylitis Index. Exploratory analyses included resolution of dactylitis based on severity, time to first resolution of dactylitis (Kaplan-Meier estimate) and resolution of dactylitis (heatmap analysis). Clinical efficacy outcomes, composite domains of disease activity, health-related quality of life (HRQoL) and radiographic progression using van der Heijde-modified total Sharp score were assessed in patients with/without dactylitis at baseline. RESULTS: Overall, 389/996 (39%) patients presented with dactylitis at baseline, had more active clinical disease and greater disease activity than those without dactylitis at baseline. Resolution of dactylitis was observed across all treatment groups at Week 104. Improvement in joints, enthesitis, skin psoriasis, nail outcomes, physical function and HRQoL were sustained over 2 years in patients with dactylitis at baseline. With secukinumab treatment, >80% of patients did not show structural radiographic progression. The proportion of non-structural radiographic progressors were comparable across patients with/without dactylitis at baseline with secukinumab treatment over 2 years. CONCLUSIONS: Patients with dactylitis at baseline were associated with higher burden of disease. Secukinumab provided sustained improvements across all clinical outcomes, QoL and inhibition of radiographic progression in PsA patients with dactylitis at baseline over 2 years.

Altered CD39 and CD73 Expression in Rheumatoid Arthritis: Implications for Disease Activity and Treatment Response.

In rheumatoid arthritis (RA) synovium, ATP, and ADP are released, sparking inflammation. Ectoenzymes CD39 and CD73 metabolize these purine nucleotides, generating anti-inflammatory adenosine. Therefore, dysregulated CD39 and CD73 expression may impact RA development. We assessed CD39 and CD73 expression in peripheral blood from 15 healthy controls (Cs) and 35 RA patients at baseline and after 3 and 6 months of tocilizumab treatment using flow cytometry. Additionally, ectoenzyme expression was examined on cultured T cells to understand activation and IL-6 effects. At baseline, RA patients exhibited a lower CD8+CD39-CD73+ cell percentage, which inversely correlated with DAS28. Additionally, they had lower percentages of Treg CD39+CD73+ and CD39-CD73- cells. Good responders tended to have lower B CD39+CD73+ cell percentages at baseline and 3 months. Additionally, Treg, CD8+ T and B cells inversely correlated with DAS28. T-cell activation increased CD39 and decreased CD73 expression, regardless of IL-6. IL-6 reduced IFNγ-secreting CD4+ T-cell percentage in Cs, but increased the percentage of IFNγ-secreting CD4+ and CD8+ T cells in RA patients. These findings indicate differing CD39 and CD73 expression in RA and Cs, influenced by T-cell activation and IL-6. Correlations between these molecules and RA activity suggest their role in dysregulated inflammation in RA.

Increase of Circulating Monocyte-Platelet Conjugates in Rheumatoid Arthritis Responders to IL-6 Blockage.

Platelets (PLT) bind to a significant percentage of circulating monocytes and this immunomodulatory interaction is increased in several inflammatory and autoimmune conditions. The therapeutic blockage of IL-6 with Tocilizumab (TCZ) alters PLT and the phenotype and function of monocytes in rheumatoid arthritis (RA). However, the relationship between monocyte−PLT conjugates (CD14+PLT+) and clinical and immunological variables and the regulation of this interaction by IL-6 blockage are still unknown. Here, we compared the presence of monocyte−PLT conjugates (CD14+PLT+) and membrane CD162 expression using flow cytometry, and, by ELISA, the markers of PLT activation (sCD62P and sCD40L) in healthy donors (HD) and patients with long-standing RA before TCZ (baseline). We found higher percentages and absolute counts of CD14+PLT+, and higher plasmatic levels of sCD62P and sCD40L but lower CD162 expression on monocytes from RA patients than those from HD. Additionally, the levels of CD14+PLT+ inversely correlated with inflammatory parameters. Interestingly, 95% of patients with lower percentages of CD14+PLT+ and only 63% of patients with higher percentages of CD14+PLT+ achieved a EULAR-defined response at four weeks (p = 0.036). After TCZ, the percentage of CD14+PLT+ increased in 92% of RA patients who achieved 12 w-remission (p < 0.001). Our results suggest that the binding of PLTs has a modulatory effect, accentuated by the increased binding of PLTs to monocytes in response to the therapeutic blockage of IL-6.

Giant pes anserinus bursitis: A rare soft tissue mass of the medial knee / Bursitis gigante de la pata de ganso: Una masa de partes blandas infrecuente de la rodilla medial

Bursae are small, jelly-like sacs that are located throughout the body, mainly around the shoulder, elbow, hip, knee, and heel in a number over 150. They contain a small amount of fluid, and are positioned between bones and soft tissues, acting as cushions to help reduce friction. Pes anserinus bursae, despite being clinically frequent, are not visible either by ultrasound (US) or magnetic resonance image (MRI). In some cases, we may observe a small fluid collection. The present case-report demonstrates the full clinical picture of a giant pes anserinus bursae beginning from clinical observation to its final pathology exam.(AU)

Las bursas son estructuras saculares gelatinosas distribuidas por todo el cuerpo; hombro, codo, cuerpo, cadera, rodilla y tobillo. Existen más de 150 y son fisiológicas. Contienen fluido y su función es protectora, evitando la fricción entre estructuras como huesos, tendones y ligamentos. La bursa anserina, a pesar de ser clínicamente frecuente, normalmente no es visible, ni mediante ecografía, ni mediante resonancia magnética. En algunos casos puede tener una pequeña colección líquida. El presente caso muestra toda la evolución de una bursa anserina gigante desde el inicio de la observación clínica, hasta su análisis anatomopatológico.(AU)

Non-invasive vagus nerve stimulation for rheumatoid arthritis: a proof-of-concept study.

BACKGROUND: Vagus nerve stimulation delivered with an implanted device has been shown to improve rheumatoid arthritis severity. We aimed to investigate the safety and efficacy of non-invasive stimulation of the auricular branch of the vagus nerve for the treatment of patients with moderately to severely active rheumatoid arthritis. METHODS: This prospective, multicentre, open-label, single-arm proof-of-concept study enrolled patients aged 18-80 years with active rheumatoid arthritis who had an inadequate response to conventional synthetic disease-modifying antirheumatic drugs (DMARDs) and up to one biological DMARD. Biological DMARDs were stopped at least 4 weeks before enrolment and concomitant use was not allowed during the study. All eligible participants were assigned to use a non-invasive, wearable vagus nerve stimulation device for up to 30 min per day, which delivered pulses of 20 kHz. Follow-up visits occurred at week 1, week 2, week 4, week 8, and week 12 after the baseline visit. The primary endpoint was the mean change in Disease Activity Score of 28 joints with C-reactive protein (DAS28-CRP) at week 12 compared with baseline. Secondary endpoints included the mean change in the Health Assessment Questionnaire-Disability Index (HAQ-DI), the proportion of patients with a minimal clinically important difference of 0·22 on HAQ-DI, the proportion achieving American College of Rheumatology (ACR) 20, ACR50, and ACR70 response, and safety analysis. This study is registered with ClinicalTrials.gov (NCT04116866). FINDINGS: Of 35 patients screened for eligibility, 30 (86%) were enrolled at six centres in Spain between Dec 27, 2018, and Oct 24, 2019, of whom 27 (90%) completed the week 12 visit. The mean change in DAS28-CRP at 12 weeks was -1·4 (95%CI -1·9 to -0·9; p<0·0001) from a mean baseline of 5·3 (SD 1·0). 11 (37%) of 30 patients reached DAS28-CRP of 3·2 or less, and seven (23%) patients reached DAS28-CRP of less than 2·6 at week 12. The mean HAQ-DI change was -0·5 (95%CI -0·7 to -0·2; p<0·0001) from a mean baseline of 1·6 (SD 0·7), and 17 (57%) patients reached a minimal clinically important difference of 0·22 or more. ACR20 responses were reached by 16 (53%) patients, ACR50 responses by 10 (33%) patients, and ACR70 by five (17%) patients. Four adverse events were reported, none of which were serious and all of which resolved without intervention. INTERPRETATION: Use of the device was well tolerated, and patients had clinically meaningful reductions in DAS28-CRP. This was an uncontrolled, open-label study, and the results must be interpreted in this context. Further evaluation in larger, controlled studies is needed to confirm whether this non-invasive approach might offer an alternative treatment for rheumatoid arthritis. FUNDING: Nesos.

A comparative study on clinical and serological characteristics between patients with rhupus and those with systemic lupus erythematosus and rheumatoid arthritis.

BACKGROUND: The concomitant presence of two autoimmune diseases - systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) - in the same patient is known as rhupus. We evaluated a group of patients with rhupus to clarify further their clinical, serological and immunogenic features in a multi-centre cohort. In addition, the study aimed to explore the utility of the 2019 European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) SLE classification criteria in our group of patients with rhupus. METHODS: This was a cross-sectional study. We included rhupus patients from 11 different rheumatology departments, and compared them to SLE and RA patients at a ratio of 2:1. All information was recorded following a pre-established protocol. RESULTS: A total of 200 patients were included: 40 rhupus patients and 80 each of SLE and RA patients as controls. Disease duration was similar among SLE and rhupus groups (around 13 years), but the RA group had a significantly lower disease duration. Main clinical manifestations were articular (94.2%), cutaneous (77.5%) and haematological (72.5%). Rhupus patients had articular manifestations similar to those expected in RA. Only 10% of rhupus patients had renal involvement compared with 25% of those with SLE (p < 0.05), while interstitial lung disease was more common in patients affected by RA. The 2019 EULAR/ACR SLE criteria were met in 92.5% of the rhupus patients and in 96.3% of the SLE cohort (p > 0.05). Excluding the joint domain, there were no differences between the numbers of patients who met the classification criteria. CONCLUSION: Rhupus patients follow a particular clinical course, with full expression of both SLE and RA in terms of organ involvement, except for a lower prevalence of kidney affection. The new 2019 EULAR/ACR SLE criteria are not useful for differentiating SLE and rhupus patients. A new way of classifying autoimmune diseases is needed to identify overlapping clusters.

Norma de calidad para el manejo del paciente con artritis psoriásica: proyecto QUANTUM / Quality standard for the management of patients with psoriatic arthritis: QUANTUM Project

OBJETIVO: Generar una norma de calidad para el manejo del paciente con artritis psoriásica (APs). MÉTODOS: Metodología cualitativa que incluyó: 1) dos grupos focales (uno con pacientes con APs y otro con especialistas no reumatólogos implicados en su cuidado); 2) revisión de la literatura publicada sobre documentos en el ámbito de la calidad asistencial en APs; 3) reunión de grupo nominal donde 15 expertos reumatólogos generaron, de forma consensuada, una serie de criterios de calidad así como fórmulas o medidas objetivas cuantificables para evaluarlas; 4) Delphi para establecer la factibilidad, prioridad y grado de acuerdo con los criterios de calidad, y 5) generación de estándares de calidad y sus atributos. Se realizó un análisis descriptivo de los resultados. RESULTADOS: Se generaron 59 estándares de calidad, 18 de los cuales de cumplimiento obligatorio, agrupados en 4 bloques según unos objetivos específicos: 1) acortar el tiempo hasta el diagnóstico (n=6); 2) optimizar el manejo de la enfermedad (n=26); 3) mejorar la colaboración multidisciplinar (n=9), y 4) mejorar la monitorización (n=18). Para evaluar el cumplimiento de estos estándares en muchos casos se revisarán las historias clínicas. Otras fuentes serán la memoria del servicio y del hospital así como los buscadores bibliográficos. En cuanto al nivel de exigencia a la hora de considerar por cumplido el estándar, algunos son de tipo sí/no, otros están desde el 50 al 100%, y en este rango muchos en el 80%. CONCLUSIONES: Esta norma de calidad debe ayudar en la mejora de la calidad de atención para el paciente con APs

OBJECTIVE: To generate a quality standard for the management of patients with psoriatic arthritis (PsA). METHODS: We employed qualitative methodology that included: 1) Two focus groups (one with patients with PsA and another with non-rheumatologist specialists involved in the care of PsA patients); 2) A narrative literature review of published documents related to the quality of care in PsA; 3) A nominal group meeting in which 15 expert rheumatologists generated and reached a consensus on a series of quality criteria, as well as formulas or quantifiable objective measures to evaluate them; 4) The Delphi method to establish the feasibility, priority and agreement with the quality criteria; 5) A final generation of standards of care and their attributes. A descriptive analysis of the results was carried out. RESULTS: A total of 59 standards of care was generated, 18 of mandatory compliance, grouped into 4 blocks according to specific objectives: 1) early diagnosis (n=6); 2) optimizing the management of the disease (n=26); 3) multidisciplinary collaboration (n=9); 4) monitoring improvement (n=18). To assess compliance with these standards of care, in many cases, the medical records will be reviewed. Other sources will be the records of the service and hospital and bibliographic databases. Regarding the level of compliance, for some of the standards of care this is yes/no; for others, compliance ranges from 50% to 100% and, in this range, in many cases, compliance was 80%. CONCLUSIONS: This set of standards of care should help improve quality of care in PsA patients

Eficacia y seguridad de los glucocorticoides en la artritis reumatoide: revisión sistemática de la literatura / Efficacy and safety of glucocorticoids in rheumatoid arthritis: systematic literature review

OBJETIVOS: 1) Revisar sistemática y críticamente la evidencia sobre las características de uso, eficacia y seguridad de los glucocorticoides (GC) en la artritis reumatoide (AR); 2) emitir recomendaciones prácticas sobre su utilización. MÉTODOS: Se realizó una revisión sistemática de la literatura con una estrategia de búsqueda bibliográfica sensible en Medline, Embase y Cochrane Library. Se seleccionaron ensayos clínicos aleatorizados que analizasen la eficacia y/o la seguridad de los GC en pacientes con AR. Dos revisores realizaron la primera selección por título y abstract y 10, la selección tras lectura en detalle y la recogida de datos. La calidad se evaluó con la escala de Jadad. En una reunión de grupo nominal con base en sus resultados se consensuaron una serie de recomendaciones. RESULTADOS: Se incluyeron 47 artículos. Los GC, en combinación con los fármacos antirreumáticos modificadores de la enfermedad, ayudan a controlar la actividad de la enfermedad y a inhibir la progresión radiográfica, especialmente en el corto-medio plazo y en las AR de inicio. Los GC pueden mejorar la función y el dolor. Distintos tipos y vías de administración son eficaces, sin que exista un esquema de tratamiento estandarizado (dosis de inicio, desescalada y duración del tratamiento con los GC) superior a otro. Los acontecimientos adversos de los GC son muy frecuentes, dependientes de la dosis, de gravedad variable, muchos de ellos leves. Se generaron 7 recomendaciones sobre el uso y la gestión del riesgo de los GC. CONCLUSIONES: Estas recomendaciones pretenden resolver algunos interrogantes clínicos habituales y facilitar la toma de decisiones con respecto al uso de GC en la AR

OBJECTIVES: 1) To systematically and critically review the evidence on the characteristics, efficacy and safety of glucocorticoids (CS) in rheumatoid arthritis (RA); 2) to generate practical recommendations. METHODS: A systematic literature review was performed through a sensitive bibliographic search strategy in Medline, Embase and the Cochrane Library. We selected randomized clinical trials that analyzed the efficacy and/or safety of CS in patients with RA. Two reviewers performed the first selection by title and abstract. Then 10 reviewers selected the studies after a detailed review of the articles and data collection. The quality of the studies was evaluated with the Jadad scale. In a nominal group meeting, based on the results of the systematic literature review, related recommendations were reached by consensus. RESULTS: A total of 47 articles were finally included. CS in combination with disease-modifying antirheumatic drugs help control disease activity and inhibit radiographic progression, especially in the short-to-medium term and in early RA. CS can also improve function and relieve pain. Different types and routes of administration are effective, but there is no standardized scheme (initial dose, tapering and duration of treatment) that is superior to others. Adverse events when using CS are very frequent and are dose-dependent and variable severity, although most are mild. Seven recommendations were generated on the use and risk management of CS. CONCLUSIONS: These recommendations aim to resolve some common clinical questions and aid in decision-making for CS use in RA

Measuring inflammation in rheumatoid arthritis with a new clinical and ultrasound index: development and initial validation.

With the aim to develop and validate a clinical + ultrasound (US) inflammation score in rheumatoid arthritis (RA) for use in clinical practice, a mixed-method study was conducted. The theoretical development of the index was achieved with qualitative methodology (discussion group and Delphi survey). Subsequently, a cross-sectional study was carried out to analyse issues related to scoring and validation of the new index. RA patients underwent clinical [28 swollen and tender joints count, patient and physician global assessment (PhGA), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP)], and US assessments [synovitis or tenosynovitis by grey-scale (GS) and power Doppler (PD) of 42 structures]. An index was created based on statistical models and expert interaction. Construct validity was tested by correlation with DAS28, SDAI, CDAI, and PhGA. Reliability was evaluated in a subgroup of patients with the intraclass correlation coefficient (ICC). US assessment, CRP, and swollen joints were the items that passed the prioritization phase (Delphi study). For the cross-sectional study, 281 patients were randomly divided into design (n = 141) and validation samples (n = 140). The combination of US sites chosen (7 bilaterally) detected the maximum proportion of synovitis and PD present. Three scoring methods were tested: semiquantitative (0-3 GS + 0-3 PD), dichotomous (0/1 GS + 0/1 PD), and qualitative (0/1 based on algorithm). All showed strong correlation with activity measures (ρ ≥ 0.60), and reliability (ICC 0.89-0.93). The index with best parameters of validity, feasibility, and reliability was the qualitative. The final index chosen was the sum of swollen joint count, US qualitative score, and CRP. The UltraSound Activity score is a valid and reliable measure of inflammation in RA equal to the sum of 28 SJC, a simplified (0/1) US assessment of 11 structures and CRP. It is necessary further investigation to demonstrate additional value over existing indices.

Ecografía Doppler de arterias temporales superficiales en la arteritis de células gigantes en una cohorte con alta sospecha clínica / Doppler ultrasonography of superficial temporal artery in a cohort of patients with strong clinical suspicion of giant cell arteritis

Fundamento y objetivo: La arteritis de células gigantes (ACG) es la vasculitis sistémica más frecuente en adultos. En los últimos años, existe un interés creciente en evaluar la utilidad de la ecografía de arterias temporales superficiales (EATS), que permite valorar la inflamación de la pared vascular. Material y métodos: Estudio de cohorte observacional y descriptivo de 120 EATS a 60 pacientes con sospecha clínica de ACG según criterios clásicos de ACR (American College of Rheumatology). Resultados: De todos los pacientes a quienes se les realizó la EATS, el 42,3% presentó diagnóstico de ACG según los criterios de clasificación ACR. La sensibilidad y la especificidad de la ecografía en nuestra cohorte de pacientes con alta sospecha clínica fueron de 81,8 y 93,3%, respectivamente, con un VPP de 90,1% y un VPN de 87,5%. Conclusión: Los resultados avalan la ecografía de arteria temporal bilateral como una técnica útil, indolora, rápida, accesible, de alta especificidad y amplia validez diagnóstica

Background and objective: Giant cell arteritis (GCA) is the most frequent systemic vasculitis in adults. In recent years, the usefulness of temporal artery ultrasound (TAUS) as a diagnostic tool to assess the underlying inflammation of the vascular wall during the inflammatory process has been under clinical investigation. Material and methods: Observational and descriptive cohort study of 120 TAUS in 60 patients with clinical suspicions of GCA, according to the ACR (American College of Rheumatology) classification criteria. Results: Among all patients who underwent ultrasound, 42.3% met clinical criteria for GCA according to ACR. Sensitivity and specificity of TAUS in our cohort with clinical suspicion was 81.8% and 93.3%, respectively. A PPV of 90.1% and a VPN of 87.5% were observed. Conclusion: Our results showed that TAUS as a useful, indolent, fast, and accessible tool with high diagnostic specificity and diagnostic value

Assessment of nutritional status by dual X-Ray absorptiometry in women with rheumatoid arthritis: A case-control study.

Rheumatoid arthritis (RA) has been related to an impairment of the nutritional status. Body mass index (BMI) has been used but questions arise about how to properly evaluate nutritional status in RA patients. Few studies have evaluated it by dual-energy X-ray absorptiometry.In women with RA, to analyze:Case-control study including 89 women with RA. The control group was composed by 100 patients affected by non-inflammatory rheumatic disorders. Study variables included age, RA duration, history, activity and disability, and in relation to nutritional status: BMI, serum albumin (ALB), whole body DXA assessment, and skeletal muscle index (SMI).Mean age of patients was 62 ±â€Š8 years, mean duration of RA was 14 ±â€Š9 years, mean disease activity score (DAS28) was 3.7 ±â€Š1.4 and mean Health Assessment Questionnaire was 0.88 ±â€Š0.77. BMI was 27.43 ±â€Š5.16 Kg/m in patients and 27.78 ±â€Š3.98 Kg/m in controls (P: ns). ALB was within normal range in all patients.By whole body DXA, RA patients presented a statistically significant lower lean mass in all locations and lower fat mass in limbs than controls. Patients had a redistribution of fat mass to trunk. Lean mass directly correlated with fat mass.Neither BMI nor ALB correlated with DXA parameters.BMI, appendicular lean mass and SMI correlated inversely with disease duration. Trunk lean mass correlated inversely, and fat mass directly, with RA disability parameters.RA patients fulfilled criteria of sarcopenia in 44% of cases versus 19% of controls (P <.001). In RA patients, regarding SMI, BMI showed a high specificity to detect sarcopenia (94% of the patients with low BMI had sarcopenia) but low sensitivity (47% of the patients with normal BMI or overweight had sarcopenia).RA patients have an impairment of nutritional status associated to disease duration that looks like sarcopenia and that is not predicted by BMI.
