The results of this study suggest that, under the assumption of same relative risk reduction of fractures in men as for women, strontium ranelate could be considered a cost-effective strategy compared with no treatment for the treatment of osteoporotic men from a Belgian healthcare payer perspective. INTRODUCTION: This study was conducted to estimate the cost-effectiveness of strontium ranelate in the treatment of osteoporotic men. METHODS: A previously validated Markov microsimulation model was adapted to estimate the cost (<euro>2,010) per quality-adjusted life-year (QALY) gained of strontium ranelate compared with no treatment. Similar efficacy data on lumbar spine and femoral neck bone mineral density (BMD) between men with osteoporosis at high risk of fracture (MALEO Trial) and postmenopausal osteoporotic women (pivotal SOTI, TROPOS trials) supports the assumption, in the base-case analysis, of the same relative risk reduction of fractures in men as for women. Analyses were conducted, from a Belgian healthcare payer perspective, in the population from the MALEO Trial who is a men population with a mean age of 73 years, and BMD T-score </=-2.5 or prevalent vertebral fracture (PVF). RESULTS: In the MALEO population, strontium ranelate compared with no treatment was estimated at <euro>49,798 and <euro>25,584 per QALY gained using efficacy data from the intent-to-treat analysis and the per-protocol analysis including only adherent patients, respectively. In men with a BMD T-score </=-2.5 or with PVF, the cost per QALY gained of strontium ranelate fall below thresholds of <euro>45,000 and <euro>25,000 per QALY gained based on efficacy data from the entire population of the clinical trial and from the per-protocol analyses, respectively. CONCLUSIONS: The results of this study suggest that, under the assumption of same relative risk reduction of fractures in men as for women, strontium ranelate could be considered cost-effective compared with no treatment for male osteoporosis.

L’objectif principal de cet ouvrage consistait à identifier les facteurs du comportement de recours aux soins de santé dans la ville de Kinshasa. Neuf facteurs historiques (1909-1960) ont été dégagés comme facteurs influant sur l’offre et l’utilisation actuelles des soins de santé à Kinshasa : (i) gratuité des soins, (ii) présence du médecin, (iii) implication des religieuses dans l’offre des soins, (iv) convention d’agrément par l’État d’hôpitaux et de dispensaires fondés par les missions religieuses afin de les subsidier, (v) exclusion de la population dans la conception, l’organisation et la gestion du système de santé mis en place, (vi) exclusion du tradipraticien du système des soins, (vii) les noirs immatriculés étaient détachés de la coutume indigène et se rapprochaient plus des Européens que des autochtones, (viii) l’enseignement et la santé étaient confiés aux mains des missions religieuses, avec une préférence pour les catholiques, (ix) le budget du secteur santé était de 12% du budget du gouvernement. De même, de 1960 à 1995, dix facteurs ont été identifiés comme influant sur l’offre et l’utilisation actuelles des soins de santé à Kinshasa : (i) mise en place d’un système à 2 échelons (fonctionnant pratiquement avec un seul échelon), excluant l’hôpital général, (ii) les animateurs de la participation communautaires est le médecin chef de zone ou l’infirmier titulaire, (iii) les membres du personnel des zones de santé sont nommés par le ministère et ceux du centre de santé par son propriétaire, (iv) la population joue le rôle de bénéficiaire passif dans le système en place, (v) absence de la population dans les organes de gestion des soins de santé primaires, (vi) mise en place d’un système comprenant moins de 10% des structures des soins disponibles, (vii) pour constituer le comité de santé, le médecin chef de zone consulte les autorités locales qui l’aident à identifier des groupes d’interlocuteurs, (viii) les fonds alloués au premier échelon sont gérés par les experts et/ou parrains et non par la population, (ix) exclusion du médecin du premier échelon, (x) système dépendant financièrement de l’aide extérieure. <br />Les résultats de l’enquête de ménage menée en 1997 montre que lors de la perception d’un problème de santé par les populations de Kinshasa, sept possibilités de recours sont exploitées : le centre de santé est le plus sollicité, suivi du dispensaire privé, l’automédication pharmaceutique, le tradipraticien, l’automédication traditionnelle, la polyclinique conventionnée et l’hôpital de référence. La régression logistique a montré que l’on recourt d’autant plus au centre de santé qu’à une autre structure de soins lorsqu’on recherche la qualité des soins, l’application de bons tarifs et l’offre de services polyvalents. Par contre, le souci de proximité géographique par rapport au lieu de résidence du ménage appelle à utiliser le dispensaire privé. Lorsqu’on recherche la présence d’un médecin ou l’existence d’une convention on choisit plutôt la polyclinique privée conventionnée. Ceux qui ont cherché une solution à un type particulier de maladie ont choisi plutôt le tradipraticien. La lecture des résultats de cette étude montre que si les populations choisissent les soins offerts par le centre de santé, c’est parce qu’elles les jugent de bonne qualité. Des soins intégrés et offerts par le même technicien, de formation requise, sont un atout majeur à l’acceptabilité du premier échelon des soins de santé primaires à Kinshasa. La proximité géographique est également une raison importante pour s’adresser à une autre structure que le centre de santé. Il est peu probable que 109 centres de santé qui doivent encore être mis en place pour réaliser le plan de couverture verront le jour à court terme. Une alternative serait d’intégrer les structures de soins privées non officielles dans le système des soins de santé primaires, pour autant qu’elles puissent atteindre un niveau de qualité comparable à celui des centres de santé. Concernant l’accessibilité financière des structures de soins, l’étude suggère qu’en dialogue avec la population, des modes de financement et de tarification en vigueur ou à mettre au point soient étudiés pour diminuer les barrières financières aux soins de qualité. Pour que le tradipraticien puisse jouer un rôle complémentaire important dans la réalisation des soins de santé primaires, même en milieu urbain, il est suggéré d’étudier la possibilité de privilégier des lieux de communication.

Summary It has been shown that antidepressants would have a direct action on bone metabolism and would be associated with increased fracture risk. Results from this large meta-analysis show that both SSRIs and TCAs are associated with a moderate and clinically significant increase in the risk of fractures of all types. Introduction This study seeks to investigate the relationship between use of antidepressants and the risk of fracture. Methods An exhaustive systematic research of case–control and cohort studies published or performed between 1966 and April 2011 that reported risk estimates of fracture associated with use of antidepressants was performed using MEDLINE, PsycINFO, and the Cochrane Systematic Review Database, manual review of the literature, and congressional abstracts. Inclusion, quality scoring, and data abstraction were performed systematically by three independent reviewers. Results A total of 34 studies (n01,217,464 individuals) were identified. Compared with non-users, the random effects pooled RR of fractures of all types, among antidepressant users, were 1.39 (95%CI 1.32–1.47). Use of antidepressants were associated with a 42 %, 47 %, and 38 % risk increase in non-vertebral, hip, and spine fractures, respectively ([For non-vertebral fractures: RR01.42, 95%CI 1.34–1.51]; [For hip fractures: RR01.47, 95%CI 1.36–1.58]; [For spine fractures: RR01.38, 95%CI 1.19–1.61]). Studies examining SSRI use showed systematically a higher increase in the risk of fractures of all types, non-vertebral, and hip fractures than studies evaluating TCA use. Conclusions Results from this large meta-analysis show that both SSRIs and TCAs are associated with a moderate and clinically significant increase in the risk of fractures of all types.

BACKGROUND: Attribute selection represents an important step in the development of discrete-choice experiments (DCEs), but is often poorly reported. In some situations, the number of attributes identified may exceed what one may find possible to pilot in a DCE. Hence, there is a need to gain insight into methods to select attributes in order to construct the final list of attributes. This study aims to test the feasibility of using the nominal group technique (NGT) to select attributes for DCEs. METHODS: Patient group discussions (4-8 participants) were convened to prioritize a list of 12 potentially important attributes for osteoporosis drug therapy. The NGT consisted of three steps: an individual ranking of the 12 attributes by importance from 1 to 12, a group discussion on each of the attributes, including a group review of the aggregate score of the initial rankings, and a second ranking task of the same attributes. RESULTS: Twenty-six osteoporotic patients participated in five NGT sessions. Most (80%) of the patients changed their ranking after the discussion. However, the average initial and final ranking did not differ markedly. In the final ranking, the most important medication attributes were effectiveness, side effects, and frequency and mode of administration. Some (15%) of the patients did not correctly rank from 1 to 12, and the order of attributes did play a role in the ranking. CONCLUSION: The NGT is feasible for selecting attributes for DCEs. Although in the context of this study, the NGT session had little impact on prioritizing attributes, this approach is rigorous, transparent, and improves the face validity of DCEs. Additional research in other contexts (different decisional problems or different diseases) is needed to determine the added value of the NGT session, to assess the optimal ranking/rating method with control of ordering effects, and to compare the attributes selected with the different approaches.

BACKGROUND: Strontium ranelate is currently used for osteoporosis. The international, double-blind, randomised, placebo-controlled Strontium ranelate Efficacy in Knee OsteoarthrItis triAl evaluated its effect on radiological progression of knee osteoarthritis. METHODS: Patients with knee osteoarthritis (Kellgren and Lawrence grade 2 or 3, and joint space width (JSW) 2.5-5 mm) were randomly allocated to strontium ranelate 1 g/day (n=558), 2 g/day (n=566) or placebo (n=559). The primary endpoint was radiographical change in JSW (medial tibiofemoral compartment) over 3 years versus placebo. Secondary endpoints included radiological progression, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, and knee pain. The trial is registered (ISRCTN41323372). RESULTS: The intention-to-treat population included 1371 patients. Treatment with strontium ranelate was associated with smaller degradations in JSW than placebo (1 g/day: -0.23 (SD 0.56) mm; 2 g/day: -0.27 (SD 0.63) mm; placebo: -0.37 (SD 0.59) mm); treatment-placebo differences were 0.14 (SE 0.04), 95% CI 0.05 to 0.23, p<0.001 for 1 g/day and 0.10 (SE 0.04), 95% CI 0.02 to 0.19, p=0.018 for 2 g/day. Fewer radiological progressors were observed with strontium ranelate (p<0.001 and p=0.012 for 1 and 2 g/day). There were greater reductions in total WOMAC score (p=0.045), pain subscore (p=0.028), physical function subscore (p=0.099) and knee pain (p=0.065) with strontium ranelate 2 g/day. Strontium ranelate was well tolerated. CONCLUSIONS: Treatment with strontium ranelate 1 and 2 g/day is associated with a significant effect on structure in patients with knee osteoarthritis, and a beneficial effect on symptoms for strontium ranelate 2 g/day.

SUMMARY: Aspects of osteoporosis in men, such as screening and identification strategies, definitions of diagnosis and intervention thresholds, and treatment options (both approved and in the pipeline) are discussed. INTRODUCTION: Awareness of osteoporosis in men is improving, although it remains under-diagnosed and under-treated. A European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO) workshop was convened to discuss osteoporosis in men and to provide a report by a panel of experts (the authors). METHODS: A debate with an expert panel on preselected topics was conducted. RESULTS AND CONCLUSIONS: Although additional fracture data are needed to endorse the clinical care of osteoporosis in men, consensus views were reached on diagnostic criteria and intervention thresholds. Empirical data in men display similarities with data acquired in women, despite pathophysiological differences, which may not be clinically relevant. Men should receive treatment at a similar 10-year fracture probability as in women. The design of mixed studies may reduce the lag between comparable treatments for osteoporosis in women becoming available in men. [less ▲]Detailed reference viewed: 3 (2 ULg)

Abstract Background: Vitamin D insufficiency has deleterious consequences on health outcomes. In elderly or postmenopausal women, it may exacerbate osteoporosis. Scope: There is currently no clear consensus on definitions of vitamin D insufficiency or minimal targets for vitamin D concentrations and proposed targets vary with the population. In view of the potential confusion for practitioners on when to treat and what to achieve, the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO) convened a meeting to provide recommendations for clinical practice, to ensure the optimal management of elderly and postmenopausal women with regard to vitamin D supplementation. Findings: Vitamin D has both skeletal and extra-skeletal benefits. Patients with serum 25-hydroxyvitamin D (25-(OH)D) levels <50 nmol/L have increased bone turnover, bone loss, and possibly mineralization defects compared with patients with levels >50 nmol/L. Similar relationships have been reported for frailty, nonvertebral and hip fracture, and all-cause mortality, with poorer outcomes at <50 nmol/L. Conclusion: The ESCEO recommends that 50 nmol/L (i.e. 20 ng/mL) should be the minimal serum 25-(OH)D concentration at the population level and in patients with osteoporosis to ensure optimal bone health. Below this threshold, supplementation is recommended at 800 to 1000 IU/day. Vitamin D supplementation is safe up to 10,000 IU/day (upper limit of safety) resulting in an upper limit of adequacy of 125 nmol/L 25-(OH)D. Daily consumption of calcium- and vitamin-D-fortified food products (e.g. yoghurt or milk) can help improve vitamin D intake. Above the threshold of 50 nmol/L, there is no clear evidence for additional benefits of supplementation. On the other hand, in fragile elderly subjects who are at elevated risk for falls and fracture, the ESCEO recommends a minimal serum 25-(OH)D level of 75 nmol/L (i.e. 30 ng/mL), for the greatest impact on fracture.

OBJECTIVE: Evaluation of the efficacy and safety of a single oral dose of a 1200 mg sachet of chondroitin 4&6 sulfate (CS 1200) vs three daily capsules of chondroitin 4&6 sulfate 400 mg (CS 3*400) (equivalence study) and vs placebo (superiority study) during 3 months, in patients with knee osteoarthritis (OA). DESIGN: Comparative, double-blind, randomized, multicenter study, including 353 patients of both genders over 45 years with knee OA. Minimum inclusion criteria were a Lequesne index (LI) >/= 7 and pain >/= 40 mm on a visual analogue scale (VAS). LI and VAS were assessed at baseline and after 1-3 months. Equivalence between CS was tested using the per-protocol procedure and superiority of CS vs placebo was tested using an intent-to-treat procedure. RESULTS: After 3 months of follow-up, no significant difference was demonstrated between the oral daily single dose of CS 1200 formulation and the three daily capsules of CS 400. Patients treated with CS 1200 or CS 3*400 were significantly improved compared to placebo after 3 months of follow-up in terms of LI (<0.001) and VAS (P < 0.01). No significant difference in terms of security and tolerability was observed between the three groups. CONCLUSION: This study suggests that a daily administration of an oral sachet of 1200 mg of chondroitin 4&6 sulfate allows a significant clinical improvement compared to a placebo, and a similar improvement when compared to a regimen of three daily capsules of 400 mg of the same active ingredient.

Background and aims: It has been previously suggested that the incidence of hip fracture is higher among people living in nursing homes than among community-dwelling people. However, it is not clear whether this is a consequence of nursing home residency or of the greater age of the residents. We have examined the relationship between the place of residence and hip fracture incidence, in a prospective 3- year study. Methods: Women from nine countries included in this study were part of the placebo group of a randomized controlled trial having assessed the long-term effect of a new antiosteoporotic drug. All women were osteoporotic and received placebo and vitamin D during the 3 years of follow-up. All the institutionalized (nursing home, medical house) women (n ¼ 217) were included in this post hoc analysis and three noninstitutionalized age- and country-matched controls were included (n ¼ 651). Results: The mean (and standard deviation) age of the patients was 80.4 (5.6) years in the institutionalized women and 80.2 (5.8) years in the noninstitutionalized women (p ¼ 0.87). After 3 years of followup, 37 fractures occurred: 12 (5.5%) in institutionalized women and 25 (3.8%) in noninstitutionalized women. The difference between the two groups was not statistically significant (p ¼ 0.29). After controlling for age, body mass index, femoral neck bone mineral density and prevalent nonvertebral fracture, the residence status of the patient (institutionalized vs. noninstitutionalized) was not significantly associated with hip fracture incidence (p ¼ 0.63). Conclusions: We suggest that living in an institutionalized place is not an independent risk factor for hip fracture for osteoporotic women receiving calcium and vitamin D.

Over the last 20 years, several studies have investigated the ability of glucosamine sulfate to improve the symptoms (pain and function) and to delay the structural progression of osteoarthritis. There is now a large, convergent body of evidence that glucosamine sulfate, given at a daily oral dose of 1,500 mg, is able to significantly reduce the symptoms of osteoarthritis in the lower limbs. This dose of glucosamine sulfate has also been shown, in two independent studies, to prevent the joint space narrowing observed at the femorotibial compartment in patients with mild-to-moderate knee osteoarthritis. This effect also translated into a 50 % reduction in the incidence of osteoarthritis-related surgery of the lower limbs during a 5-year period following the withdrawal of the treatment. Some discrepancies have been described between the results of studies performed with a patent-protected formulation of glucosamine sulfate distributed as a drug and those having used glucosamine preparations purchased from global suppliers, packaged, and sold over-the-counter as nutritional supplements.

We analyzed the relationships between bone mineral density (BMD) or bone turnover marker (BTM) changes and vertebral fracture incidence in women treated with bazedoxifene using a post hoc analysis from a 3-year randomized, placebo-controlled study evaluating the effect of bazedoxifene (20 or 40 mg) on fracture risk reduction. BMD was assessed at baseline and every 6 months for 3 years. Osteocalcin and C-telopeptide of type I collagen were assessed at baseline and at 3, 12, and 36 months. Vertebral fractures were assessed with a semiquantitative visual assessment. Data were available for 5,244 women, of whom 3,476 were treated with bazedoxifene. Using a logistic regression analysis and the classical Li approach, the proportion of fracture incidence explained by BMD change after 3 years of bazedoxifene treatment was 29 % for the total hip and 44 % for the femoral neck. The proportion of treatment explained by lumbar BMD change could not be quantified accurately because of the significant interaction between treatment and change in BMD. With the same model, the 12-month BTM changes explained up to 29 % of the fracture risk reduction observed with the two forms of bazedoxifene. In women treated with bazedoxifene, changes in femoral neck BMD, hip BMD, or BTMs explained a moderate proportion of the fracture risk reduction observed during the 3 years of follow-up. However, BMD or BTM changes cannot be recommended for individual monitoring of women treated with bazedoxifene. [less ▲]Detailed reference viewed: 10 (2 ULg)

Objective To assess health-related quality of life (HRQOL) in a prospective study with 7 years of follow-up in 49 consecutive patients who underwent a total joint replacement because of osteoarthritis. Methods Generic HRQOL was assessed with the shortform 36 (SF-36) and specific HRQOL with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Results Out of the 39 subjects who have completed the 7 years of follow-up of this study, 22 (56.4 %) underwent a hip replacement surgery and the other 17 (43.6 %) a knee replacement. Six months after surgery, a significant improvement, compared to preoperative scores, was observed in two of the eight dimensions of the SF-36 (i.e. physical function and pain). The same dimensions, pain and physical function, at the same time, 6 months after surgery, measured by the WOMAC, showed a significant improvement as well, but there was no significant change in the stiffness score. From 6 months to the end of followup, changes in SF-36 scores showed a significant improvement in physical function (p = 0.008), role-physical (p = 0.004) and role-emotional (p = 0.01) while all scores of the WOMAC improved (p\0.001 for pain, p\0.001 for stiffness and p\0.01 for physical function). Conclusion The improvements observed in HRQOL at short term after surgery, are at least maintained over a 7-year follow-up period. [less ▲]Detailed reference viewed: 28 (13 ULg)
