RESUMEN
The Asian and Latin America Fracture Observational Study (ALAFOS) is a prospective, observational, single-arm study conducted in 20 countries across Asia, Latin America and the Middle East. ALAFOS evaluated new clinical vertebral and non-vertebral fragility fractures in relation to time on teriparatide, in postmenopausal women with osteoporosis in real-life clinical practice. Clinical fragility fractures, back pain, and health-related quality of life (HRQoL) were recorded in 6-month intervals for ≤ 24 months during teriparatide treatment and up to 12-months post-treatment. Data were analysed with piecewise exponential regression with inverse probability weighting for time to event outcomes and mixed-model repeated measures for back pain and HRQoL. 3054 postmenopausal women started teriparatide and attended ≥ one follow-up visit (mean [SD] age 72.5 [10.4] years). The median (95% CI) time to treatment discontinuation was 22.0 months (21.2, 22.8). During the treatment period, 111 patients (3.6%) sustained 126 clinical fractures (2.98 fractures/100 patient-years). Rates of new clinical fragility fractures were significantly decreased during the > 6-12, > 12-18, and > 18-24-month periods, as compared with the first 6 months of treatment (hazard ratio [HR] 0.57; 95% CI 0.37, 0.88; p = 0.012; HR 0.35; 95% CI 0.19, 0.62; p < 0.001; HR 0.43; 95% CI 0.23, 0.83; p = 0.011; respectively). Patients also reported an improvement in back pain and HRQoL (p < 0.001). These results provide data on the real-world effectiveness of teriparatide in the ALAFOS regions and are consistent with other studies showing reduction of fractures after 6 months of teriparatide treatment. These results should be interpreted in the context of the noncontrolled design of this observational study.

BACKGROUND: The justification for this consensus is the absence of local protocols on Medication-Related Osteonecrosis of the Jaws (MONJ), for prevention, evaluation, and treatment, involving physicians and dentists, leading to suspension of antiresorptive treatments, despite their benefit in the prevention of fragility fractures (40-70%). These fractures cause disability and mortality (80% and 20-30%, respectively), as opposed to the low risk associated with MONJ in osteoporotic (0.01-0.03%) and oncological patients (1.3-1.8%). PURPOSE: To provide management recommendations through algorithms that guide health professionals to prevent, diagnose, and treat MONJ in different clinical scenarios. METHOD: A technical multidisciplinary team composed of specialists with extensive experience in osteoporosis or osteonecrosis of the jaw from Fundación Santa Fé (Bogotá, Colombia) and the Asociación Colombiana de Osteoporosis y Metabolismo Mineral was selected. Three rounds were carried out: definition of questions, answers using Delphi methodology, and the discussion of questions in order to have an agreement. The whole group participated in two phases, and the developer group in the total number of rounds. A literature review was conducted to obtain academic support to design questions with clinical relevance. RESULTS AND CONCLUSIONS: The consensus group generated definitions and recommendations useful for doctors and dentists, following clinical algorithms involving four scenarios: osteoporosis patient who requires dental procedures and has not received antiresorptives, osteoporosis patient who are under treatment with antiresorptives, cancer patients, and MONJ-instituted patients. The therapeutic approach in osteoporosis and cancer patients, in invasive dental procedures, must be relied on the risk-benefit treatment.

BACKGROUND: Osteoporosis is a major healthcare concern in Latin America. Factors such as changing demographics, fragmented healthcare systems, and financial considerations may result in a huge increase in the burden of osteoporosis in this region. The aim of this article is to describe the baseline clinical characteristics and fracture history of patients who are prescribed teriparatide in normal clinical practice in Latin America. METHODS: We conducted a prospective, multinational, observational study (the Asia and Latin America Fracture Observational Study [ALAFOS]) in 20 countries worldwide to assess the incidence of fractures in postmenopausal women with osteoporosis receiving teriparatide as a part of routine clinical practice in a real-world setting. In this subregional analysis of the ALAFOS study, we report the clinical characteristics, fracture history, risk factors for osteoporosis, comorbidities, previous osteoporosis therapies and health-related quality of life measures at baseline for patients from the four participant Latin American countries: Argentina, Brazil, Colombia, and Mexico. RESULTS: The Latin America subregional cohort included 546 postmenopausal women (mean [SD] age: 71.0 [10.1] years; range: 40-94 years), constituting 18% of the ALAFOS total population. The baseline mean (SD) bone mineral density T-scores were - 3.02 (1.23) at the lumbar spine and - 2.31 (0.96) at the femoral neck; 62.8% of patients had a history of low trauma fracture after the age of 40 years and 39.7% of patients had experienced ≥1 fall in the past year. Osteoporosis medications were used by 70.9% of patients before initiating teriparatide. The median (Q1, Q3) EQ-5D-5 L Visual Analog Scale (VAS) scores for perceived health status at baseline was 70 (50, 80). The mean (SD) worst back pain numeric rating scale score for the overall Latin American cohort was 4.3 (3.4) at baseline. CONCLUSIONS: This baseline analysis of the Latin America subregion of the ALAFOS study indicates that patients who are prescribed teriparatide in the four participant countries had severe osteoporosis and high prevalence of fractures. They also had back pain and poor health-related quality of life. The proportions of patients with severe or extreme problems on the EQ-5D-5 L individual domains were lower than those in the overall ALAFOS study population.

OBJECTIVE: To describe the study design and baseline patient characteristics of the Asia and Latin America Fracture Observational Study (ALAFOS) to better understand the profile of patients receiving teriparatide during the course of routine clinical practice in Asia, Latin America, the Middle East and Russia. METHODS: Prospective, observational, non-interventional study in postmenopausal women with osteoporosis who are prescribed teriparatide for up to 24 months, according to local medical standards, with a 12 month post-treatment follow-up. MEASURES: Demographics, risk factors for osteoporosis and fractures, history of fracture, prior osteoporosis medications, comorbidities, physical function, back pain and quality of life (QoL). RESULTS: In total 3031 postmenopausal women (mean age 72.5 years) recruited at 152 sites in 20 countries were analyzed; 62.9% had a history of fragility fracture after age 40 (33.0% of patients with spinal, 14.2% with hip fractures). The mean (SD) bone mineral density T-scores at baseline were -3.06 (1.40) and -2.60 (1.05) at the lumbar spine and femoral neck, respectively. At entry, 43.7% of patients were naïve to prior osteoporosis treatments; 40.5% of patients reported ≥1 fall in the past year. The median (Q1; Q3) EuroQoL Visual Analog Scale (EQ-VAS) for perceived overall health status was 60 (50; 80). The mean (SD) worst back pain Numeric Rating Scale in the last 24 hours was 4.6 (3.3). CONCLUSIONS: Our data indicates that patients who were prescribed teriparatide in the ALAFOS participant countries had severe osteoporosis, high prevalence of fractures, disabling back pain and poor QoL. The frequency of patients receiving prior osteoporosis medications was lower than in previous observational studies conducted in other locations.

BACKGROUND: The authors determined incidence of osteonecrosis of the jaw (ONJ) in a large, prospective three-year clinical trial of zoledronic acid in women with postmenopausal osteoporosis (PMO). METHODS: A total of 7,714 women with PMO received intravenous zoledronic acid 5 mg or a placebo. No spontaneous reports of ONJ were received. An independent, blinded adjudication committee searched the trial's adverse event database by using 60 terms. On an ongoing basis, the committee reviewed the identified events, and it defined ONJ as exposed bone in the maxillofacial area with delayed healing for more than six weeks despite appropriate care. RESULTS: One participant who received a placebo and one participant who received zoledronic acid experienced delayed healing associated with infection. Both conditions resolved after antibiotic therapy, débridement or both. CONCLUSION: The occurrence of ONJ is rare in a PMO population, and delayed healing of lesions can occur with and without bisphosphonate use over three years. CLINICAL IMPLICATIONS: The low incidence of ONJ must be assessed in the context of the clinical benefit of zoledronic acid therapy in reducing hip, vertebral and nonvertebral fractures in this at-risk population. There is no evidence to suggest that healthy patients with osteoporosis who are receiving bisphosphonates require any special treatment beyond routine dental care or to support altering standard treatment practices.

BACKGROUND: Etoricoxib is a highly selective COX-2 inhibitor which was evaluated for the treatment of rheumatoid arthritis (RA). METHODS: Double-blind, randomized, placebo and active comparator-controlled, 12-week study conducted at 67 sites in 28 countries. Eligible patients were chronic NSAID users who demonstrated a clinical worsening of arthritis upon withdrawal of prestudy NSAIDs. Patients received either placebo, etoricoxib 90 mg once daily, or naproxen 500 mg twice daily (2:2:1 allocation ratio). Primary efficacy measures included direct assessment of arthritis by counts of tender and swollen joints, and patient and investigator global assessments of disease activity. Key secondary measures included the Stanford Health Assessment Questionnaire, patient global assessment of pain, and the percentage of patients who achieved ACR20 responder criteria response (a composite of pain, inflammation, function, and global assessments). Tolerability was assessed by adverse events and routine laboratory evaluations. RESULTS: 1171 patients were screened, 891 patients were randomized (N = 357 for placebo, N = 353 for etoricoxib, and N = 181 for naproxen), and 687 completed 12 weeks of treatment (N = 242 for placebo, N = 294 for etoricoxib, and N = 151 for naproxen). Compared with patients receiving placebo, patients receiving etoricoxib and naproxen showed significant improvements in all efficacy endpoints (p<0.05). Treatment responses were similar between the etoricoxib and naproxen groups for all endpoints. The percentage of patients who achieved ACR20 responder criteria response was 41% in the placebo group, 59% in the etoricoxib group, and 58% in the naproxen group. Etoricoxib and naproxen were both generally well tolerated. CONCLUSIONS: In this study, etoricoxib 90 mg once daily was more effective than placebo and similar in efficacy to naproxen 500 mg twice daily for treating patients with RA over 12 weeks. Etoricoxib 90 mg was generally well tolerated in RA patients.

Objective: To describe clinical and paraclinical involvement in RP in a Colombian populationand compare it with another series previously published.Methods and materials: Retrospective review of 19 cases of RP presented in 4 rheumatologycenters in our country in the last 10 years. All patients met diagnostic criteria previouslyestablished. In every case, each clinical feature was analized and then compared with another9 series of RP previously published between 1966 y 2007.Results: Mean age at diagnosis was 46 years. A female predominance was observed ina relation 4:1. Mean follow-up was 4 years. Auricular condritis was the initial clinicalfeature in 89 percent of patients and finally was observed in the 100 percent of our report. Comparedwith other series, we found less frequently arthritis (21percent), ocular (10percent) and dermatologicinvolvement (10percent). Renal and neurologic involvement and the association between RPand another autoimmune disorder were found in the expected frequency. We not observedany cardiovascular involvement in our serie. All of the patients received corticosteroidsand 57percent had had another immunosuppressive medication. Observed mortality was 10percentby complications associated to RP.Conclusions: In contrast with another series from Caucasian and Oriental population, weobserved a marked predominance of female sex, a minor frequency of systemic involvementand auricular condritis is our most frequent initial clinical feature. Probably, these findingsare the result of a different genetic, immunological and environmental background.

Objetivos: el objetivo del estudio fue evaluar la respuesta al tratamiento y seguridad del alendronato de sodio en una presentación de cápsulas blandas de gelatina (Neobon 70 ®), en mujeres posmenopáusicas con osteoporosis u osteopenia. Métodos: estudio clínico multicéntrico abierto a un año de tratamiento en mujeres postmenopáusicas. Las pacientes fueron asignadas a recibir 70 mg cada semana de alendronato sódico en presentación de cápsulas de gelatina blanda. Los desenlaces primarios fueron la densidad mineral ósea medida por DEXA y el valor plasmático del C-Telopéptido. La condición ósea fue evaluada por densitometría al inicio del estudio, al mes 6 y a los 12 meses de tratamiento. La resorción ósea fue evaluada por los niveles de C-Telopéptido basal, a los 3, 6 y 12 meses de tratamiento. Como desenlace secundario se evaluó la presentación de eventos adversos secundarios. Resultados: el estudio incluyó 146 mujeres reclutadas en diez centros de consulta externa de reumatología en cuatro ciudades de Colombia, que tuvieran diagnóstico de osteoporosis u osteopenia. La media de edad fue de 67±8 años (rango entre 45,7 y 92,8 años), y el promedio de tiempo transcurrido desde el inicio de la menopausia fue de 16±7,8 años. Treinta pacientes (20,54%) tenían una historia de fracturas previas. Al mes 12 de tratamiento se observó una reducción clínica y estadísticamente significativa en el nivel del C-Telopéptido (basal 0,53, tercer mes 0,22, sexto mes 0,17 y al año 0,17, p < 0,00001). Adicionalmente, se observó una mejoría estadísticamente significativa con el tratamiento en los valores del T-score a nivel de vértebras lumbares L2-L4 (basal -2,57, al sexto mes -2,27 y -2,29 al año), en el cuello de fémur (basal -2,37, al sexto mes -1,98 y al año -1,99), en el trocánter (basal -1,95, al sexto mes -1,55, y al año -1,41) y en la cadera (basal -1,73, al sexto mes -1,6 y -1,57 al año). También se observó mejoría en los parámetros de densidad mineral ósea, con un incremento de 2,3% a nivel vertebral lumbar y 2,59% en cadera. No hubo cambios en la densidad mineral ósea a nivel de cuello de fémur y trocánter. Estos cambios son similares a los observados con otras presentaciones de alendronatos y bifosfonatos. Como eventos adversos relacionados, solo se observó en el 8,2% la presencia de síntomas dispépticos, vértigo en el 3,4%, cefalea en el 2,7% y estreñimiento en el 1,4%. Conclusiones: estos resultados muestran que la presentación de alendronato sódico en cápsulas de gelatina blanda produce una gran mejoría en los parámetros evaluados por la densitometría y en el C-Telopéptido en mujeres posmenopáusicas con osteoporosis u osteopenia, y es una presentación farmacológica segura en mujeres jóvenes y de mayor edad.
Objectives: the purpose of this study was to evaluate the response to treatment and safety of Sodium Alendronate in a soft gelatin capsules presentation (Neobon 70 ®), in a postmenopausal women with osteoporosis or osteopenia. Methods: open multicenter clinical trial during one year was conducted in postmenopausal women. The patients were assigned to receive 70 mg of Sodic Alendronate in a soft gelatin capsule presentation, once time per week. The primaries endpoints were the bone density mineral measured by DEXA and the C-telopeptide serum level. The bone condition was evaluated by basal bone densitometry, 6 and 12 months. The bone resortion was evaluated by basal C-telopeptide serum levels, to 3, 6 and 12 months. The secondary endpoint was the presentation of secondary adverse events. Results: the study included 146 patients recruited in 10 rheumatologic clinical centers in Colombia, with diagnosis of osteopenia or osteporosis. Mean aged was 67±8 years (range 45.7 to 92.8 years) and the mean duration of menopausal time was 16±7.8 years. Thirty patients (20.54%) had a history of previous fracture bone. At month 12, a statistically significant reduction from base line in mean of C-telopeptide serum level was observed (basal 0.53, 3 month 0.22, 6 month 0.17 and 12 month 0.17, p < 0.00001). In addition, there was a clinical and statistically significant improvement in the T-score with the treatment in lumbar vertebrae L2-L4 (basal -2.57, 6 month -2.27 and 12 month -2.29), femur (basal -2.37, 6 month -1.98 and 12 month -1.99), trochanter (basal -1.95, 6 month -1.55 and 12 month -1.41), and in hip (basal -1.73, 6 month -1.6 and 12 month -1.57). Also it was observed an improvement in the parameters of bone density of 2.3% at lumbar vertebral level and of 2.59% in hip. No significant changes were observed in a left neck femur and trochanter. These increases are similar to observed with other presentations of alendronates and biphosphonates. Among this population, only the 8.2% had dyspeptic symptoms, 3.4% vertigo, 2.7% cephalea and 1.4% constipation. Conclusion: these findings showed that the presentation of sodium Alendronate in soft gelatin capsules produced a greater improvement in bone markers and densitometry scores in postmenopausal women with osteoporosis and osteopenia and is a safety pharmacological presentation in young and older patients.
