Long-term use of high-dose corticosteroids often results in bone loss, which may lead to osteoporosis-related fractures. This was a multicenter, double-blind study in which 290 ambulatory men and women receiving high-dose oral corticosteroid therapy (prednisone > 7.5 mg/day or equivalent) for 6 or more months were randomized to receive placebo, risedronate 2.5 mg/day, or risedronate 5 mg/day for 12 months. All patients received calcium 1 g and vitamin D 400 IU daily. The primary endpoint was lumbar spine bone mineral density (BMD) at month 12. Additional measurements included BMD at the femoral neck and trochanter and the incidence of vertebral fractures. Overall, there were statistically significant treatment effects on BMD at 12 months at the lumbar spine (p < 0.001), femoral neck (p ؍ 0.004), and trochanter (p ؍ 0.010). Risedronate 5 mg increased BMD at 12 months by a mean (SEM) of 2.9% (0.49%) at the lumbar spine, 1.8% (0.46%) at the femoral neck, and 2.4% (0.54%) at the trochanter, whereas BMD was maintained only in the control group. Although not powered to show fracture efficacy, we observed a reduction in the incidence of vertebral fractures of 70% in the combined risedronate treatment groups, relative to placebo (p ؍ 0.042). Risedronate was well tolerated, had a good safety profile, and was not associated with gastrointestinal adverse events. We conclude that risedronate increases BMD and potentially reduces the incidence of vertebral fractures in patients with corticosteroid-induced osteoporosis. (J Bone Miner Res 2000;15:1006 -1013)
Men and women (n = 518) receiving moderate-to-high doses of corticosteroids were enrolled in two studies with similar protocols and randomly assigned to receive either placebo or risedronate (2.5 or 5 mg) for 1 year. All patients received daily calcium supplementation (500-1000 mg), and most also received supplemental vitamin D (400 IU). The primary endpoint was the difference between the placebo and active groups in lumbar spine bone mineral density (BMD) at 1 year; changes in BMD at other sites, biochemical markers of bone turnover, and the incidence of vertebral fractures were also assessed. In the overall population, the mean (SE) lumbar spine BMD increased 1.9 +/- 0.38% from baseline in the risedronate 5 mg group (P < 0.001) and decreased 1.0 +/- 0.4% in the placebo group (P = 0. 005). BMD at the femoral neck, trochanter, and distal radius increased or was maintained with risedronate 5 mg treatment, but decreased in the placebo group. Midshaft radius BMD did not change significantly in either treatment group. The difference in BMD between the risedronate 5 mg and placebo groups was significant at all skeletal sites (P < 0.05) except the midshaft radius at 1 year. The 2.5 mg dose also had a positive effect on BMD, although of a lesser magnitude than that seen with risedronate 5 mg. A significant reduction of 70% in vertebral fracture risk was observed in the risedronate 5 mg group compared with the placebo group (P = 0.01). Risedronate was efficacious in both men and women, irrespective of underlying disease and duration of corticosteroid therapy, and had a favorable safety profile, with a similar incidence of upper gastrointestinal adverse events in the placebo and active treatment groups. Daily treatment with risedronate 5 mg significantly increases BMD and decreases vertebral fracture risk in patients receiving moderate-to-high doses of corticosteroid therapy.
Objective. The objective of this study was to explore patients’ experiences of RA daily life while on modern treatments.Methods. The methods of this study comprised semi-structured interviews with 15 RA patients, analysed using inductive thematic analysis.Results. Four themes suggest patients experience life with RA along a continuum from RA in the background to the foreground of their lives, underpinned by constant actions to maintain balance. Living with RA in the background shows patients experience continuous, daily symptoms, which they mediate through micromanagement (mediating the impact of RA on daily life), while learning to incorporate RA into their identity (redefining me). RA moving into the foreground shows patients experience fluctuating symptoms (unwelcome reminders) that may or may not lead to a flare (trying to make sense of fluctuation). Dealing with RA in the foreground shows how patients attempt to manage RA flares (trying to regain control) and decide to seek medical help only after feeling they are losing control. Patients employ a stepped approach to self-management (mediation ladder) as symptoms increase, with seeking medical help often seen as the last resort. Patients seek to find a balance between managing their fluctuating RA and living their daily lives.Conclusion. Patients move back and forth along a continuum of RA in the background vs the foreground by balancing self-management of symptoms and everyday life. Clinicians need to appreciate that daily micromanagement is needed, even on current treatment regimes. Further research is needed to quantify the level and impact of daily symptoms and identify barriers and facilitators to seeking help.
Independent risk factors for fracture include advanced age, preexisting fractures, and low bone mineral density. Rised-ronate has been shown in several large trials to be safe and effective for patients with osteoporosis, but its effects in populations at high risk are not well characterized. To determine the effect of risedronate on vertebral fracture in high-risk subjects, we pooled data from two randomized, double-blind studies [Vertebral Efficacy with Risedronate Therapy (VERT) Multinational (VERT-MN) and VERT-North America (VERT-NA)] in 3684 postmenopausal osteoporotic women treated with placebo or risedronate 2.5 or 5 mg/d and analyzed fracture risk in subgroups of subjects at high risk for fracture due to greater age or more prevalent fractures (vs. median for overall study population), or lower bone mineral density (T-score, -2.5 or less). Fractures were diagnosed by quantitative and semiquantitative assessment of radiographs at baseline and 1 yr. In the overall population, treatment for 1 yr with risedronate 5 mg/d reduced the risk of new vertebral fractures by 62% vs. control (relative risk, 0.38; 95% confidence interval, 0.25, 0.56; P < 0.001) and of multiple new vertebral fractures by 90% vs. control (relative risk, 0.10; 95% confidence interval, 0.04, 0.26; P < 0.001). Consistent risk reductions were observed at 1 yr in the risedronate-treated high-risk subgroups. Significant reduction in fracture risk after 1 yr is an important benefit in patients at high risk for fracture because, without treatment, these patients are likely to sustain new fractures in the near term.
Osteoporosis is a well-recognized adverse effect of corticosteroid therapy. This study aimed to investigate the effect of etidronate, intermittent cyclical therapy, in the prevention of corticosteroid-induced bone loss. Patients with various medical conditions starting high-dose corticosteroid therapy were enrolled in the study. The treatment had to be expected to continue for at least 12 months with the initial 90 days at a mean daily dose of at least 7.5 mg of prednisone, with subsequent treatment of at least 2.5 mg/day. One hundred seventeen patients were randomly assigned oral etidronate 400 mg/day, or placebo, for 14 days, followed by 76 days of oral calcium carbonate (500 mg elemental calcium), cycled over 12 months. The primary outcome measure was the difference in percent change from baseline in bone mineral density of the lumbar spine between the groups at the end of year 1. Secondary measures included changes in femur bone density and in biochemical markers of bone remodeling. The mean (+/- SEM) lumbar spine bone density changed 0.30 +/- 0.61% and -2.79 +/- 0.63% in the etidronate and placebo groups, respectively. The mean difference between groups after 1 yr was 3.0 +/- 0.84% (P = 0.004). The changes in the femoral neck and great trochanter were not different between the groups. There was a decrease in pyridinium crosslinks, significant from baseline at both 6 and 12 months, in the etidronate group. Osteocalcin increased in the placebo group, and difference between groups was -25.07 +/- 14.89% (P = 0.032) and -34.68 +/- 19.77% (P = 0.051), at 6 and 12 months respectively. There was no significant difference between the groups in number of adverse experiences, including gastrointestinal disorders. Etidronate intermittent cyclical therapy prevents lumbar vertebral bone loss in patients starting high-dose corticosteroid therapy.
Rheumatoid arthritis (RA) is a systemic inflammatory disease with a particular predilection for causing pain, deformity and functional limitation affecting the hands. Measures of the severity of RA, such as the disease activity score with 28 joint count may not fully reflect the regional impact of RA on the hands. Hand grip strength measurements are a form of objective assessment that focuses specifically on the hands in RA. This review explores what is currently known about the assessment of hand grip strength; what it may indicate, how it is measured, some of the practical aspects and challenges associated with performing these tests, and how this information can be applied in a clinical setting. It summarises the role that grip strength has in assessing patients with RA and finishes with some recommendations for how to use grip strength measurements in clinical practice, and what direction future research might take.
Objectives: The OMERACT Polymyalgia Rheumatica Working Group aims to develop a core set of outcome measures to be used in clinical trials for PMR. Previously-reported work from OMERACT 11 included a qualitative study of the patient experience and a preliminary literature review. Methods:A three-round Delphi survey of clinicians and PMR patients was undertaken to identify a candidate core domain set for PMR research. Additionally a literature review of outcome measures and their respective measurement instruments was undertaken. Meetings of patient research partners and clinicians were convened in order to review face validity of the provisional core domain set, which was subsequently presented and discussed at the OMERACT 12 congress.Results: Of the 60 clinicians taking part in Round 1, 55 took part in round 2 and 51 in round 3. Of the 55 patients that took part in round 1, 46 and 35 took part in subsequent rounds. 91% of participants in round 3 deemed the resulting draft core domain set reasonable. The literature review identified 28 studies for full review. Measurement instruments for each proposed domain were identified. Clinicians are highly aware of glucocorticoid-related adverse effects, but there is relatively little evidence about their true prevalence and severity especially in PMR. Conclusions:A provisional core domain set is presented for clinical trials in PMR, comprising: acute phase markers, physical function, death, glucocorticoid-related adverse events and development of giant cell arteritis. Measurement instruments are suggested that may cover each domain but these require formal validation for clinical trials in PMR.
