ABSTRACT
Resumen: Introducción: la mayoría de las fracturas por fragilidad ocurren en rango densitométrico de osteopenia, la escala ósea trabecular (TBS) permite valorar aspectos de la microarquitectura que influyen en la resistencia ósea. Objetivo: describir las características clínicas y los hallazgos de la microarquitectura ósea aplicando TBS combinado con densitometría ósea (DXA) en un grupo de pacientes. Material y métodos: estudio descriptivo, de recolección retrospectiva. Se incluyen los pacientes a los que se les realizó DXA con TBS en el INRU en julio y agosto de 2020. Resultados: se analizaron 194 pacientes, 173 (89%) de sexo femenino y 21 (11%) de sexo masculino. El 36,1% (70 pacientes) en rango de osteopenia, 36,1 (70 pacientes) en rango de osteoporosis. El 32,9% (23 pacientes) con osteopenia y el 47,1% (33 pacientes) con osteoporosis tenían microarquitectura degradada. 76,9% de los pacientes con artritis reumatoidea y 45,8% de los que tenían espondiloartritis presentaban microarquitectura alterada. Conclusiones: el TBS permitió reestratificar el riesgo de fractura en un número importante de pacientes, mostrándose como una herramienta muy útil en la valoración complementaria de la salud ósea.
Summary: Introduction: most fractures that result from bone fragility occur in the osteopenia range The trabecular bone score (TBS) enables the assessment of microarchitecture aspects that impact bone resistance. Objective: to describe the clinical characteristics and findings of bone microarchitecture, by applying TBS and bone densitometry in a group of patients. Method: descriptive study of retrospective collection. Patients who were included in the study underwent a Dual-energy X-ray Absorptiometry (DXA) with TBS at the National Rheumatology Service between July and August, 2020. Results: 94 patients were analysed, 173 (89%) were female and 21 (11%) were male. 36.1% (70 patients) lay in the osteopenia range, 36.1 (70 patients) in the osteoporotic range. 32.9% (23 patients) with osteopenia and 47.1% (33 patients) with osteoporosis evidenced a degraded bone microarchitecture. 76.9 % of patients with rheumatoid arthritis and 45.8 % of patients with spondyloarthritis respectively evidenced altered bone microarchitecture. Conclusions: TBS allowed stratification of fracture risk in a significant number of patients, which may suggest it is a useful tool for complementary assessment of bone health.
Resumo: Introdução: a maioria das fraturas por fragilidade ocorre na faixa densitométrica da osteopenia; o escore de osso trabecular (TBS) permite avaliar aspectos da microarquitetura que influenciam a resistência óssea. Objetivo: descrever as características clínicas e os achados da microarquitetura óssea aplicando TBS combinado com densitometria óssea (DMO) em um grupo de pacientes. Material e métodos: estudo descritivo, retrospectivo, incluindo pacientes que realizaram DXA (absorciometria de raios-X de dupla energia) com TBS no INRU em julho e agosto de 2020. Resultados: foram analisados 194 pacientes, 173 (89%) mulheres e 21 (11%) homens. 36,1% (70 pacientes) na faixa de osteopenia, 36,1 (70 pacientes) na faixa de osteoporose. 32,9% (23 pacientes) com osteopenia e 47,1% (33 pacientes) com osteoporose tinham microarquitetura degradada. Nos pacientes com artrite reumatoide 76,9% e nas espondiloartrite 45,8% apresentaram microarquitetura alterada, respectivamente. Conclusões: a TBS permitiu fazer uma nova estratificação do risco de fratura em um número significativo de pacientes, mostrando-se uma ferramenta muito útil na avaliação complementar da saúde óssea.

OBJECTIVE: The objective of this consensus is to update the recommendations for the treatment of hand, hip, and knee osteoarthritis (OA) by agreeing on key propositions relating to the management of hand, hip, and knee OA, by identifying and critically appraising research evidence for the effectiveness of the treatments and by generating recommendations based on a combination of the available evidence and expert opinion of 18 countries of America. METHODS: Recommendations were developed by a group of 48 specialists of rheumatologists, members of other medical disciplines (orthopedics and physiatrists), and three patients, one for each location of OA. A systematic review of existing articles, meta-analyses, and guidelines for the management of hand, hip, and knee OA published between 2008 and January 2014 was undertaken. The scores for Level of Evidence and Grade of Recommendation were proposed and fully consented within the committee based on The American Heart Association Evidence-Based Scoring System. The level of agreement was established through a variation of Delphi technique. RESULTS: Both "strong" and "conditional" recommendations are given for management of hand, hip, and knee OA and nonpharmacological, pharmacological, and surgical modalities of treatment are presented according to the different levels of agreement. CONCLUSIONS: These recommendations are based on the consensus of clinical experts from a wide range of disciplines taking available evidence into account while balancing the benefits and risks of nonpharmacological, pharmacological, and surgical treatment modalities, and incorporating their preferences and values. Different backgrounds in terms of patient education or drug availability in different countries were not evaluated but will be important.

BACKGROUND: Latin America is a heterogeneous region made up of different populations, cultures, latitudes, altitudes, and immigrants from different areas and ethnic groups. OBJECTIVE: The purpose of this study is to describe the clinical and demographic profile of patients with osteoarthritis (OA) evaluated by a selected group of rheumatologists in 13 Latin American countries. METHODS: A descriptive, observational, cross-sectional study was conducted in 13 Latin American countries of patients with symptomatic OA. Data were collected over a 3-month period using an ad hoc questionnaire to evaluate the clinical and demographic features of OA seen by rheumatologists. RESULTS: Among the 3040 patients, their average age was 62.5 years, and female-to-male ratio was 4.8:1. Patients with body mass index of greater than 30 kg/m or obesity was found in 38.2%. Approximately 88% had primary OA. Joints with OA were as follows: knee 31.2%, hand 9.5%, hand and knee 22.9%, proximal and distal interphalangeal joints (erosive OA) 6.5%, axial 6.6%, and hip 1.3%. Approximately 88.5% had radiographic severity of grade 2 or 3 on Kellgren-Lawrence scale (0-4). Nonsteroidal anti-inflammatory drugs were the predominant OA treatment included in combinations with glucosamine sulfate/chondroitin and viscosupplementation. Associated comorbidities included hypertension (39%), obesity (36.3%), diabetes mellitus (12%), and without comorbidity (12.7%). CONCLUSIONS: This is 1 of the largest population studies that evaluated the characteristics of OA in 3040 patients evaluated by rheumatologists in 13 Latin American countries. This study provides important data for each Latin American country to develop new health care planning in management of OA.
