INTRODUCTION AND AIM: T-score bone mineral density (BMD) thresholds may influence guidance for treatment in patients under glucocorticoid (GC) therapy. Different BMD thresholds have been described but there is no international consensus. The aim of this study was to find a threshold to help in treatment decision-making in the population under GC therapy. METHODS: A working group representing three scientific societies from Argentina was convened. The first team was formed by specialists with expertise in glucocorticoid-induced osteoporosis (GIO) who voted according to summary of evidence. The second team was constituted by a methodology group who coordinated and supervised each stage. We conducted two systematic reviews to synthesize the evidence. The first included trials of drugs used in GIO to analyze the BMD cut-off used as inclusion criteria. In the second, we analyzed the evidence regarding the densitometric thresholds to discriminate between fractured and non-fractured patients under GC treatment. RESULTS: In the first review, 31 articles were included for qualitative synthesis and more than 90% of the trials included patients regardless of their densitometric T-score or range of osteopenia. In the second review, 4 articles were included and more than 80% of the T-scores were in the range -1.6 to -2.0. The summary of findings was analyzed and put to a vote. CONCLUSIONS: With more than 80% agreement of the voting expert panel, a T-score≤-1.7 was considered the most appropriate for treatment in postmenopausal women and men over 50 years of age under GC therapy. This study could help in treatment decision-making in patients under GC therapy without fractures but other fracture risk factors should certainly be considered.

Introducción y objetivo: Los umbrales del T-score de densidad mineral ósea (DMO) podrían influir en el tratamiento de pacientes bajo terapia con glucocorticoides (GC). Se han descrito diferentes umbrales, pero no existe un consenso internacional. El objetivo de este trabajo fue encontrar un umbral que ayude en la decisión terapéutica en la población bajo tratamiento con GC. Métodos: Se convocó un grupo de trabajo en representación de tres sociedades científicas de Argentina. El primer equipo estuvo formado por especialistas con experiencia en osteoporosis inducida por glucocorticoides (OIG), quienes estuvieron a cargo de la votación basada en la evidencia. El segundo equipo estuvo a cargo de la metodología coordinando y supervisando cada etapa. Realizamos dos revisiones sistemáticas: la primera incluyó ensayos de fármacos utilizados en OIG para analizar el T-score considerado como criterio de inclusión. En la segunda, analizamos la evidencia sobre umbrales densitométricos para la discriminación de pacientes fracturados y no fracturados bajo tratamiento con GC. Resultados: En la primera revisión se incluyeron 31 artículos donde se halló que más de 90% de los ensayos incluyeron pacientes independientemente del T-score o en el rango de osteopenia. En la segunda revisión se incluyeron cuatro artículos donde observamos que más de 80% de los valores de T-score se encontraban entre -1,6 y -2,0. Conclusiones: Con un acuerdo superior a 80% del panel de expertos, un T-score ≤ -1,7 se consideró el más adecuado para el tratamiento en mujeres posmenopáusicas y hombres mayores de 50 años bajo tratamiento con GC. Este estudio podría ayudar en la decisión terapéutica en pacientes bajo tratamiento con GC sin fracturas, pero ciertamente deberían considerarse otros factores de riesgos de fracturas complementarios.(AU)

La osteoporosis inducida por glucocorticoides (OIC) es la causa más común de osteoporosis secundaria. La pérdida ósea se produce en forma temprana, en los primeros meses siguientes a la introducción de los glucocorticoides (GC), dependiendo de la dosis diaria. La patogénesis es multifactorial y el principal efecto deletéreo es la inhibición de la formación ósea. Los GC inducen fracturas por fragilidad ósea, especialmente en la columna vertebral, y esto genera incapacidad funcional. En los últimos años se han publicado algunas guías internacionales elaboradas por consenso para la prevención y el tratamiento de la OIC. La Sociedad Argentina de Osteoporosis designó a un grupo de trabajo para elaborar una guía propia y actualizada para el diagnóstico, la prevención y el tratamiento de la OIC (GE-OIC-SAO). (AU)
Glucocorticoid-induced osteoporosis (GIO) is the most common cause of secondary osteoporosis. It occurs early, with rapid bone loss in the first few weeks after the initiation of the treatment, with a rate that is dependent mainly on the daily dose. While the pathogenesis is multifactorial, the highest inhibitory effect occurs on bone formation. Glucocorticoids induce fragility fractures, especially in spine, generating functional disability. In recent years, there have been some international guidelines developed by consensus for the prevention and treatment of GIO. The Argentinean Osteoporosis Society appointed a working group to prepare a national guide updating the diagnosis, prevention and treatment of GIO. (AU)

The goals of this study were to ascertain damage in patients with systemic lupus erythematosus (SLE) from five rheumatologic centres in Argentina and to examine overall damage, damage by domain and damage by item within each domain. We performed a retrospective observational study including patients with SLE (ACR 1997 revised and modified criteria) from five rheumatology centres in Argentina. Organ damage was scored using the SLICC/ACR DI (SDI), ascertained at years 1, 2, 5 and 10. Three centres provided information up to the fifth year. Of the 197 patients, 88.3% were women and their mean age was 33.2 years. The mean disease duration and follow-up were 7.6 and 5.3 years, respectively. Damage accrued gradually over time with SDI ranging from 0.52 (+/-1.1) at year 1 up to 2.46 (+/-2.1) at year 10. The renal system was the most involved system, followed by the neuropsychiatric, the cardiovascular and the musculoskeletal systems. Proteinuria, cognitive impairment, pericarditis, avascular necrosis, cataract and alopecia were the predominant items in their respective systems. Systems such as peripheral vascular, pulmonary, gastrointestinal, diabetes, malignancy and premature gonadal failure were not frequent. Overall SDI had a gradual increase over time. Damage in each domain of SDI, except for diabetes, had a similar behaviour. Behaviour of items in each domain varied.
