RESUMO
OBJECTIVES: i) To explore the agreement between the OMERACT ultrasound lesions of enthesitis and physical examination in assessing enthesitis in spondyloarthritis (SpA) patients; ii) To investigate the prevalence and clinical relevance of subclinical enthesitis in this population. METHODS: Twenty rheumatology centres participated in this cross-sectional study. SpA patients, including axial SpA (axSpA) and psoriatic arthritis (PsA) patients, underwent both ultrasound scan and physical examination of large lower limb entheses. The OMERACT ultrasound lesions of enthesitis were considered, along with a recently proposed definition for 'active enthesitis' by our group. Subclinical enthesitis was defined as the presence of 'active enthesitis' in ≥1 enthesis in SpA patients without clinical enthesitis (i.e., number of positive entheses on physical examination and Leeds Enthesitis Index score =0). RESULTS: 4130 entheses in 413 SpA patients (224 axSpA/189 PsA) were evaluated through ultrasound and physical examination. Agreement between ultrasound and physical examination ranged from moderate (i.e., enthesophytes) to almost perfect (i.e., power Doppler and 'active enthesitis'). Patellar tendon entheses demonstrated the highest agreement, whereas Achilles tendon insertion showed the lowest. Among 158/413 (38.3%) SpA patients with clinical enthesitis, 108 (68.4%) exhibited no 'active enthesitis' on ultrasound. Conversely, of those 255 without clinical enthesitis, 39 (15.3%) showed subclinical enthesitis. Subclinical enthesitis was strongly associated with local structural damage. However, no differences were observed regarding the demographic and clinical profiles of SpA patients with and without subclinical enthesitis. CONCLUSIONS: Our study underscores the need for a comprehensive tool integrating ultrasound and physical examination for assessing enthesitis in SpA patients.
RESUMO
OBJECTIVES: To assess, in spondyloarthritis (SpA), the discriminative value of the Outcome Measures in Rheumatology (OMERACT) ultrasound lesions of enthesitis and their associations with clinical features in this population. METHODS: In this multicentre study involving 20 rheumatology centres, clinical and ultrasound examinations of the lower limb large entheses were performed in 413 patients with SpA (axial SpA and psoriatic arthritis) and 282 disease controls (osteoarthritis and fibromyalgia). 'Active enthesitis' was defined as (1) power Doppler (PD) at the enthesis grade ≥1 plus entheseal thickening and/or hypoechoic areas, or (2) PD grade >1 (independent of the presence of entheseal thickening and/or hypoechoic areas). RESULTS: In the univariate analysis, all OMERACT lesions except enthesophytes/calcifications showed a significant association with SpA. PD (OR=8.77, 95% CI 4.40 to 19.20, p<0.001) and bone erosions (OR=4.75, 95% CI 2.43 to 10.10, p<0.001) retained this association in the multivariate analysis. Among the lower limb entheses, only the Achilles tendon was significantly associated with SpA (OR=1.93, 95% CI 1.30 to 2.88, p<0.001) in the multivariate analyses. Active enthesitis showed a significant association with SpA (OR=9.20, 95% CI 4.21 to 23.20, p<0.001), and unlike the individual OMERACT ultrasound lesions it was consistently associated with most clinical measures of SpA disease activity and severity in the regression analyses. CONCLUSIONS: This large multicentre study assessed the value of different ultrasound findings of enthesitis in SpA, identifying the most discriminative ultrasound lesions and entheseal sites for SpA. Ultrasound could differentiate between SpA-related enthesitis and other forms of entheseal pathology (ie, mechanical enthesitis), thus improving the assessment of entheseal involvement in SpA.

A b s t r a c t Purpose: To describe health-related QOL (HRQOL) in patients with musculoskeletal symptoms, compared to a population with other comorbidities, and a healthy population. Methods: A cross-sectional study was carried out on an open population involved in a community-oriented program for control of rheumatic diseases (COPCORD) study in Colombia, using EQ-5D-3L for estimating QOL, and the health assessment questionnaire disability index (HAQ-DI) for functional capacity. Results: Out of the total 4020 individuals evaluated, 2274 had rheumatic diseases, 642 had non-rheumatic diseases, and 1104 were healthy subjects. Spondyloarthritis (SpA) and rheumatoid arthritis (RA) patients had more complaints regarding pain/discomfort and mobility. As for daily activities, the diseases that mostly affected them were systemic lupus erythematosus (SLE) and RA. RA and fibromyalgia (FM) patients had the worst scores as regards anxiety/depression and self-care dimensions. FM patients had the lowest QOL measured by EQ-VAS (57.7 ± 26.2). The most frequent non-rheumatic diseases were cardiovascular and mental disorders, with 20% of these patients having a moderate level of pain/discomfort and anxiety/depression. The rheumatic patients reported a decrease in functional capacity (HAQ: 0.49), in contrast to the healthy population (0.01), and the population having other diseases (0.06). Conclusion: Rheumatic disease patients in Colombia had the worst QOL compared to the healthy population and patients with other comorbidities. Rheumatic patients had greater functional limitations, even more so when having comorbidities. This study revealed potential factors of interest requiring the attention of public health authorities, and for improving patients' QOL.
RESUMEN Objetivo: Describir la calidad de vida relacionada con la salud en pacientes con síntomas musculoesqueléticos, en comparación con pacientes con enfermedades no reumáticas y una población sana. Métodos: Se realizó un estudio transversal en comunidad abierta, en personas involucradas en un programa orientado a la comunidad para el control de enfermedades reumáticas (COP-CORD) en Colombia, utilizando el EQ-5D-3L para estimar la calidad de vida y el cuestionario de evaluación de la salud (HAQ- DI) para la capacidad funcional. Resultados: Se evaluaron 4.020 individuos; 2.274 tenían enfermedades reumáticas, 642 tenían enfermedades no reumáticas y 1.104 eran sujetos sanos. Los pacientes con espondiloartritis (SpA) y artritis reumatoide (AR) tuvieron mayores quejas con respecto al dolor/malestar y la movilidad. En cuanto a las actividades diarias, los enfermos con lupus eritematoso sistémico (LES) y AR fueron los más afectados. Los pacientes con AR y fibromialgia (FM) tuvieron las peores puntuaciones en ansiedad/depresión en las dimensiones de cuidado personal. Los pacientes con FM tuvieron la calidad de vida más baja medida por EQ-VAS (57,7 ± 26,2). Las enfermedades no reumáticas más frecuentes fueron los trastornos cardiovasculares y mentales; el 20% de estos pacientes tenía un nivel moderado de dolor/malestar y ansiedad/depresión. Los pacientes reumáticos reportaron una disminución de la capacidad funcional (HAQ: 0,49); en contraste con la población sana (0,01) y la población con otras enfermedades (0,06). Conclusión: Los pacientes con enfermedades reumáticas en Colombia tuvieron la peor calidad de vida en comparación con la población sana y los pacientes con otras enfermedades. Los pacientes reumáticos tuvieron una mayor limitación funcional, incluso más que los que tenían otras enfermedades. Este estudio reveló posibles factores relacionados con las enfermedades reumáticas que requieren la atención de las autoridades de salud pública con el objetivo de mejorar la calidad de vida de los pacientes.

Vasculitides associated with anti-neutrophil cytoplasmic antibodies are heterogeneous, systemic, low prevalence and high morbidity and mortality entities. They include granulomatosis with polyangiitis, microscopic polyangiitis and eosinophilic granulomatosis with polyangiitis. In Latin America, there are few descriptive registries of these patients. The objective of the study was to describe the demographic and clinical characteristics and in-hospital morbidity and mortality of patients with vasculitis associated with anti-neutrophil cytoplasmic antibodies in a university hospital in Colombia. This was a cross-sectional descriptive study. We performed computer searches with terms related to patients with anti-neutrophil cytoplasmic antibody-associated vasculitis, between 2005 and 2017 who met the American College of Rheumatology classification criteria for vasculitis associated with anti-neutrophil cytoplasmic antibodies, and their clinical and laboratory characteristics. One hundred and six patients with anti-neutrophil cytoplasmic antibody-associated vasculitis were included in the study. The average age was 55 years, and 57.5% were women. In 68.8% of the cases, the diagnosis was made during hospitalization, with an average hospital stay of 16.6 days (± 12.22). The distribution by type of vasculitis was: granulomatosis with polyangiitis 52%, microscopic polyangiitis 45.2% and eosinophilic granulomatosis with polyangiitis 1.8%. Alveolar hemorrhage occurred in 35% of patients; 20.7% had variable renal involvement, of which 53.8% progressed to advanced kidney disease. Treatment included glucocorticoids 91.5%, cyclophosphamide 62.2%, plasmapheresis 14.1%, and 41.5% required renal replacement therapy. In-hospital mortality was 16.5%, Sepsis was the most common cause of death. We present clinical information on a group of patients with anti-neutrophil cytoplasmic antibody-associated vasculitis; renal involvement was the the most common type of affectation. Both the clinical and serological characteristics of our registry were similar to those described in other Latin American and European cohorts, and a lower in-hospital mortality rate was evidenced.

B-cell depletion therapy is an effective option for the treatment of rheumatoid arthritis but often does not result in complete B-cell depletion. Complete B-cell depletion after rituximab treatment is associated with clinical response, and this outcome leads to long-term maintenance of therapy. Low pretreatment plasmablast counts, concomitant treatment with disease-modifying antirheumatic drugs, no smoking exposure, the presence of anticitrullinated protein antibodies or rheumatoid factor, and a low interferon signature are all predictive of complete B-cell depletion and clinical response. Half of patients who initially show complete B-cell depletion and clinical response after rituximab treatment eventually lose responsiveness with further infusions. However three-quarters of these patients regain this outcome in their following treatment cycle, suggesting that loss of response is reversible and that patients can still benefit from rituximab retreatment. The efficacy of reduced doses of rituximab is being investigated, but preliminary results suggest that these strategies are best used for maintenance therapy, particularly in patients who suffer adverse events or who are at a high risk of infection. Infusion-related reactions are the most common adverse events associated with rituximab treatment, and monitoring of IgG concentrations is crucial, as low concentrations are correlated with an increased risk of infection.
