Abstract Objective: The osteoporosis drug strontium ranelate dissociates bone remodelling processes. It also inhibits subchondral bone resorption and stimulates cartilage matrix formation in vitro. Exploratory studies in the osteoporosis trials report that strontium ranelate reduces biomarkers of cartilage degradation, and attenuates the progression and clinical symptoms of spinal osteoarthritis, suggesting symptom- and structure-modifying activity in osteoarthritis. We describe the rationale and design of a randomised trial evaluating the efficacy and safety of strontium ranelate in knee osteoarthritis. Research design, methods, and results: This double-blind, placebo-controlled trial (98 centres, 18 countries) includes ambulatory Caucasian men and women aged >/=50 years with primary knee osteoarthritis of the medial tibiofemoral compartment (Kellgren and Lawrence grade 2 or 3), joint space width (JSW) 2.5 to 5 mm, and knee pain on most days in the previous month (intensity >/=40 mm on a visual analogue scale). Patients are randomly allocated to three groups (strontium ranelate 1 or 2 g/day, or placebo). Follow-up is expected to last 3 years. The primary endpoint is radiographic change in JSW from baseline in each group versus placebo. The main clinical secondary endpoint is WOMAC score at the knee. Safety is assessed at every visit. It is estimated that 1600 patients are required to establish statistical significance with power >90% (0.2 mm +/- 10% between-group difference in change in JSW over 3 years). Recruitment started in April 2006. The results are expected in spring 2012. Clinical trial registration: The trial is registered on www.controlled-trials.com (number ISRCTN41323372). Conclusions: This randomised, double blind, placebo-controlled study will establish the potential of strontium ranelate in improving structure and symptoms in patients with knee osteoarthritis.

This study summarizes the treatment effect of zoledronic acid infusion on lumbar spine bone mineral density in different subgroups with glucocorticoid-induced osteoporosis. Zoledronic acid is significantly more effective than risedronate in increasing lumbar spine (LS) bone mineral density (BMD) in both prevention and treatment of glucocorticoid-induced osteoporosis. INTRODUCTION: In patients on glucocorticoids, a single zoledronic acid infusion significantly increased BMD versus daily oral risedronate. We assessed treatment effect on LS BMD in different patient subgroups at month 12 that contributed to the risk of osteoporosis in addition to glucocorticoids. METHODS: Patients randomized to a single IV infusion of zoledronic acid 5 mg or risedronate (5 mg/day) and stratified based on glucocorticoids duration [treatment (>3 months) and prevention (</=3 months) subpopulations] were subgrouped by age; gender; menopausal status in women; dose and duration of prednisone during the trial; and baseline serum 25-OH vitamin D, LS BMD T-score, creatinine clearance, and concomitant medication use. RESULTS: At month 12, zoledronic acid significantly increased LS BMD versus risedronate in patients </=74 years (P < 0.05) in the treatment and 65-74 years (P = 0.0008) in the prevention subpopulation. At month 12, zoledronic acid significantly increased LS BMD versus risedronate in both subpopulations irrespective of gender (all P < 0.05), cumulative prednisone dose (all P < 0.01), and postmenopausal status (all P < 0.05). In premenopausal women, in both subpopulations, zoledronic acid significantly increased total hip BMD (all P < 0.05) versus risedronate at month 12 but not LS BMD. Osteoporotic patients in the prevention (P = 0.0189) and osteopenic patients in the treatment subpopulation (P = 0.0305) showed significant LS BMD increases with zoledronic acid versus risedronate at month 12. CONCLUSIONS: This post hoc analysis suggests that zoledronic acid is significantly more effective than risedronate in increasing LS BMD in prevention and treatment of glucocorticoid-induced osteoporosis across a wide range of patients.

Effect of collagen hydrolysate in articular pain: A 6-month randomized, double-blind, placebo controlled study

Objective: Evaluation of the efficacy and safety of a food supplement made of collagen hydrolysate 1200 mg/day versus placebo during 6 months, in subjects with joint pain at the lower or upper limbs or at the lumbar spine. Design: Comparative double-blind randomized multicenter study in parallel groups. Setting: 200 patients of both genders of at least 50 years old with joint pain assessed as ≥30 mm on a visual analogical scale (VAS). Intervention: Collagen hydrolysate 1200 mg/day or placebo during 6 months. Main outcome measure: Comparison of the percentage of clinical responder between the active collagen hydrolysate group and the placebo group after 6 months of study. A responder subject was defined as a subject experiencing a clinically significant improvement (i.e. by 20% or more) in the most painful joint using the VAS score. All analyses were performed using an intent-totreat procedure. Results: At 6 months, the proportion of clinical responders to the treatment, according to VAS scores, was significantly higher in the collagen hydrolysate (CH) group 51.6%, compared to the placebo group 36.5% (p < 0.05). However, there was no significant difference between groups at 3 months (44.1% vs. 39.6%, p = 0.53). No significant difference in terms of security and tolerability was observed between the two groups. Conclusions: This study suggests that collagen hydrolysate 1200 mg/day could increase the number of clinical responders (i.e. improvement of at least 20% on the VAS) compared to placebo. More studies are needed to confirm the clinical interest of this food supplement. [less ▲]
