          Abstract

          Resumen Introducción: El empleo de los condroprotectores se presentó como una estrategia mejor encaminada al tratamiento de la artrosis por su efecto modulador y mayor seguridad. Sin embargo, su empleo es discutido y serán retirados de la financiación por el Sistema Nacional de salud (SNS). El objetivo fue revisar y comparar los condroprotectores en términos de eficacia (sobre dolor, función y estrechamiento articular), seguridad y rentabilidad en el manejo de la artrosis. Metodología: Se ha realizado una búsqueda bibliográfica de la literatura. Las bases de datos utilizadas fueron Medline y Scopus. Se revisó guía médica de la ESCEO (European Society for Clinical and Economic Aspects of Osteoarthritis), estudio epidemiológico de la Sociedad Española de Reumatología y fichas técnicas de medicamentos de la Agencia Española del Medicamento. Resultados: Se identificaron un total de 152 artículos con los algoritmos de búsqueda utilizados y los criterios de inclusión/exclusión aplicados. Después de leer títulos y resúmenes, 79 fueron excluidos porque no adecuarse a la calidad metodológica requerida o tratar otras aplicaciones diferentes a la artrosis. Tras la lectura íntegra del resto de artículos, se seleccionaron 36 artículos que se adaptaban al objetivo de este trabajo. Conclusiones: Los ensayos clínicos que evaluaron la diacereína y el condroitín sulfato tuvieron diseños muy variables que podrían justificar la variabilidad de los resultados obtenidos. Con la desfinanciación de estos fármacos por el SNS, el ahorro esperado podría revertirse por el empleo de recursos sanitarios más costosos en el futuro dado el enfoque a corto plazo de las terapias permanentes.

          Abstract Introduction: The use of chondroprotectives was presented as a better strategy aimed at the treatment of osteoarthritis due to its attributed chondromodulatory effect and greater safety. However, their use is disputed. The aim of the present work was to review and compare the chondroprotectives in terms of efficacy (on pain, function and joint narrowing), safety and economic profitability in the management of osteoarthritis. Methodology: A bibliographic search of the literature published has been carried out. The databases used were Medline and Scopus. The medical guide of the ESCEO (European Society for Clinical and Economic Aspects of Osteoathritis), the epidemiological study of the Spanish Society of Rheumatology and the technical sheets of medicines of the Spanish Agency of Medicines were reviewed. Results: A total of 152 articles were identified with the search algorithms used and the inclusion/exclusion criteria applied. After having read titles and abstracts, 79 were excluded because they did not conform to the required methodological quality or to treat other applications other than osteoarthritis. After reading the rest of the articles in their entirety, 36 articles were finally selected that were adapted to the objective of this work. Conclusions: The clinical trials that evaluated diacerein and chondroitin sulfate had highly variable designs that could justify the variability of the results obtained. With the underfunding of these drugs by the SNS, the expected savings could be reversed by the use of more expensive healthcare resources in the future given the short-term focus of permanent therapies.

          Global, regional and national burden of osteoarthritis 1990-2017: a systematic analysis of the Global Burden of Disease Study 2017

          To report the level and trends of prevalence, incidence and years lived with disability (YLDs) for osteoarthritis (OA) in 195 countries and territories from 1990 to 2017 by age, sex and Socio-demographic index (SDI; a composite of sociodemographic factors). Publicly available modelled data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 were used. The burden of OA was estimated for 195 countries and territories from 1990 to 2017, through a systematic analysis of prevalence and incidence modelled data using the methods reported in the GBD 2017 Study. All estimates were presented as counts and age-standardised rates per 100 000 population, with uncertainty intervals (UIs). Globally, the age-standardised point prevalence and annual incidence rate of OA in 2017 were 3754.2 (95% UI 3389.4 to 4187.6) and 181.2 (95% UI 162.6 to 202.4) per 100 000, an increase of 9.3% (95% UI 8% to 10.7%) and 8.2% (95% UI 7.1% to 9.4%) from 1990, respectively. In addition, global age-standardised YLD rate in 2017 was 118.8 (95% UI 59.5 to 236.2), an increase of 9.6% (95% UI 8.3% to 11.1%) from 1990. The global prevalence was higher in women and increased with age, peaking at the >95 age group among women and men in 2017. Generally, a positive association was found between the age-standardised YLD rate and SDI at the regional and national levels. Age-standardised prevalence of OA in 2017 ranged from 2090.3 to 6128.1 cases per 100 000 population. United States (6128.1 (95% UI 5729.3 to 6582.9)), American Samoa (5281 (95% UI 4688 to 5965.9)) and Kuwait (5234.6 (95% UI 4643.2 to 5953.6)) had the three highest levels of age-standardised prevalence. Oman (29.6% (95% UI 24.8% to 34.9%)), Equatorial Guinea (28.6% (95% UI 24.4% to 33.7%)) and the United States 23.2% (95% UI 16.4% to 30.5%)) showed the highest increase in the age-standardised prevalence during 1990–2017. OA is a major public health challenge. While there is remarkable international variation in the prevalence, incidence and YLDs due to OA, the burden is increasing in most countries. It is expected to continue with increased life expectancy and ageing of the global population. Improving population and policy maker awareness of risk factors, including overweight and injury, and the importance and benefits of management of OA, together with providing health services for an increasing number of people living with OA, are recommended for management of the future burden of this condition.

            An updated algorithm recommendation for the management of knee osteoarthritis from the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO)

            The European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO) sought to revisit the 2014 algorithm recommendations for knee osteoarthritis (OA), in light of recent efficacy and safety evidence, in order to develop an updated stepwise algorithm that provides practical guidance for the prescribing physician that is applicable in Europe and internationally.

              Glucosamine sulfate use and delay of progression of knee osteoarthritis: a 3-year, randomized, placebo-controlled, double-blind study.

              Conventional symptomatic treatments for osteoarthritis do not favorably affect disease progression. The aim of this randomized, placebo-controlled trial was to determine whether long-term (3-year) treatment with glucosamine sulfate can modify the progression of joint structure and symptom changes in knee osteoarthritis, as previously suggested. Two hundred two patients with knee osteoarthritis (using American College of Rheumatology criteria) were randomized to receive oral glucosamine sulfate, 1500 mg once a day, or placebo. Changes in radiographic minimum joint space width were measured in the medial compartment of the tibiofemoral joint, and symptoms were assessed using the algo-functional indexes of Lequesne and WOMAC (Western Ontario and McMaster Universities). Osteoarthritis was of mild to moderate severity at enrollment, with average joint space widths of slightly less than 4 mm and a Lequesne index score of less than 9 points. Progressive joint space narrowing with placebo use was -0.19 mm (95% confidence interval, -0.29 to -0.09 mm) after 3 years. Conversely, there was no average change with glucosamine sulfate use (0.04 mm; 95% confidence interval, -0.06 to 0.14 mm), with a significant difference between groups (P =.001). Fewer patients treated with glucosamine sulfate experienced predefined severe narrowings (>0.5 mm): 5% vs 14% (P =.05). Symptoms improved modestly with placebo use but as much as 20% to 25% with glucosamine sulfate use, with significant final differences on the Lequesne index and the WOMAC total index and pain, function, and stiffness subscales. Safety was good and without differences between groups. Long-term treatment with glucosamine sulfate retarded the progression of knee osteoarthritis, possibly determining disease modification.
