OBJECTIVE: Osteoarthritis (OA) epidemiologic data are scarce in Europe. To estimate the prevalence of symptomatic knee and hip OA in a multiregional sample in France. DESIGN: A two-phase population-based survey was conducted in six regions in 2007-2009. On initial phone contact using random-digit dialing, subjects 40-75 years old were screened with a validated questionnaire. Subjects screened positive were invited for ascertainment: physical examination and hip and/or knee radiography (Kellgren-Lawrence grade≥2). Multiple imputation for data missing not-at-random was used to account for refusals. RESULTS: Of 63,232 homes contacted, 27,632 were eligible, 9621 subjects screened positive, 3707 participated fully in the ascertainment phase, and 1010 had symptomatic OA: 317 hip, 756 knee. Hip OA prevalence according to age class ranged from 0.9% to 3.9% for men and 0.7-5.1% for women. Knee OA ranged from 2.1% to 10.1% for men and 1.6-14.9% for women. Both differed by geographical region. The hip and knee standardized prevalence was 1.9% and 4.7% for men and 2.5% and 6.6% for women, respectively. CONCLUSIONS: This confirmed the feasibility of using a screening questionnaire for eliciting population-based estimates of OA. In France, it increases with age and is greater among women above the age of 50. The geographical disparity of hip and knee OA parallels the distribution of obesity.

OBJECTIVE: To develop evidence-based recommendations for the diagnosis of knee osteoarthritis (OA). METHODS: The multidisciplinary guideline development group, representing 12 European countries, generated 10 key propositions regarding diagnosis using a Delphi consensus approach. For each recommendation, research evidence was searched systematically. Whenever possible, the sensitivity, specificity and likelihood ratio were calculated for individual diagnostic indicators and a diagnostic ladder was developed using Bayes' method. Secondary analyses were undertaken to test directly the recommendations using multiple predictive models in two populations from the UK and the Netherlands. Strength of recommendation was assessed by the EULAR visual analogue scale. RESULTS: Recommendations covered the definition of knee OA and its risk factors, subsets, typical symptoms and signs, the use of imaging and laboratory tests and differential diagnosis. Three symptoms (persistent knee pain, limited morning stiffness and reduced function) and three signs (crepitus, restricted movement and bony enlargement) appeared to be the most useful. Assuming a 12.5% background prevalence of knee OA in adults aged > or =45 years, the estimated probability of having radiographic knee OA increased with increasing number of positive features, to 99% when all six symptoms and signs were present. The performance of the recommendations in the study populations varied according to the definition of knee OA, background risk and number of tests applied. CONCLUSION: 10 key recommendations for diagnosis of knee OA were developed using both research evidence and expert consensus. Although there is no agreed reference standard, thorough clinical assessment alone can provide a confident rule-in diagnosis.

OBJECTIVE: To assess the performance of a telephone-administered questionnaire suitable for use in 2-phase surveys in the detection of symptomatic hip and knee osteoarthritis (OA) cases. METHODS: A questionnaire was designed based on typical symptoms and self-reported OA diagnosis. Three groups of subjects were consecutively enrolled from rheumatology units at French university hospitals. The disease status, based on American College of Rheumatology criteria, was first confirmed by a rheumatologist. Subjects then completed the screening questionnaire administered by interviewers unaware of the diagnosis and the clinical examination results. Three screening strategies were evaluated. RESULTS: In all, 119 subjects with hip OA, 137 with knee OA, and 111 subjects with other rheumatic diseases with lower extremity symptoms were recruited. The highest sensitivity for both hip and knee OA was obtained with the strategy based on reporting the presence or absence of symptoms (>96%). The specificity of this strategy was low (42% for both joints). When taking into account the self-reported OA diagnosis, the sensitivity slightly decreased (>91%), and the specificity increased greatly, from 76% to 78%. The highest specificity was obtained with the third strategy, requiring a rheumatologist opinion (from 82% to 85%) at the expense of lower sensitivity (>90%). CONCLUSION: The questionnaire tested in this study is a simple, valid, and reliable instrument to screen symptomatic hip and knee OA. As such, it fails to reach complete accuracy and clinical examination and radiographs remain necessary for complete ascertainment procedure.

A 23-year-old man presented with osteoporosis, revealed by femoral fractures, and a history of nephrolithiasis, short stature, metabolic acidosis, hypokalemia and ovalocytosis, a red blood cell abnormality common in malaria endemic regions. Biological investigations led to the diagnosis of type 1 distal renal tubular acidosis (dRTA). Ovalocytosis and dRTA may co-exist in the same patient, since both can originate in mutations of the anion-exchanger 1 (AE1) gene, which codes for band 3, the bicarbonate/chloride exchanger, present in both the red cell membrane and the basolateral membrane of the collecting tubule alpha-intercalated cell.

OBJECTIVE: To study the feasibility and validity of a two-step telephone screening procedure for symptomatic knee and hip osteoarthritis (OA) in the general population. METHOD: The screening questionnaire was based on signs and symptoms, previous diagnosis of OA and validated OA criteria. A random sample of telephone numbers was obtained and, at each number, one person aged 40-75 years was included. A physical examination and knee or hip radiographs were offered when the screen was positive. A sample of subjects with negative screens was also examined. The diagnosis of hip/knee OA was based on the American College of Rheumatology criteria for signs and symptoms and Kellgren-Lawrence radiographic stage 2 or greater. Prevalence rates were estimated with correction for the performance of the screening procedure. RESULTS: Of 1380 subjects, 479 had positive screens, among whom 109 were evaluated; symptomatic radiographic OA was found in 50 subjects, at the knee (n = 35) or hip (n = 20). Corrected prevalence estimates of symptomatic OA were 7.6% (6.4%-8.8%) for the knee and 5% (3.9%-6.1%) for the hip. The screening procedure had 87% (95% CI 79% to 95%) sensitivity and 92% (95% CI 91% to 93%) specificity for detecting knee OA and respectively 93% (95% CI 86% to 100%) and 93% (95% CI 92% to 94%) for hip OA. CONCLUSION: This study establishes the feasibility of telephone screening for symptomatic knee/hip OA, which could be used for a nationwide prevalence study. Pain and previous OA diagnosis were the best items for detecting symptomatic OA.

Osteoporosis accompanying severe mastocytosis leads to numerous compressed vertebrae. We treated four patients (mean age 52 years) with severe osteoporosis and mastocytosis proven by bone marrow biopsy (more than 40 mast cells/mm3), according to the following protocol: interferon alpha (IFN) 3 million units (MU) three times a week, reduced to 1.5 MU three times a week in the event of intolerance, and pamidronate (Pam) 90 mg/month in infusion. This treatment was given for 2 years. It was followed by Pam alone at a dose of 90 mg/month. After 3 or 4 years of treatment, no patient presented new vertebral or extravertebral fractures. The mean increase in bone mineral density (BMD) with IFN and Pam was 16.05+/-6.12% at the spine, 5+/-2.24% at the femoral neck, and 4.12+/-3.03% for the whole body; the increase or loss of BMD with Pam alone was +0.2+/-2.13% at the spine, -2.25+/-2.78% at the femoral neck, and -0.1+/-3.35% for the whole body. In one patient, the IFN dose was halved because of a flu-like syndrome, and in another IFN was discontinued at one year for the same reason. The association of IFN and Pam led to a major increase in bone marrow density in osteoporosis with concomitant mastocytosis and this gain was then maintained by monthly infusions of Pam.

Our aim was to compare the analgesic efficacy of pamidronate (PAM) and synthetic human calcitonin (CT) in intravenous infusion for recent painful benign vertebral compression in a randomised prospective double-blind study. Twenty-seven patients aged 49-85 years with painful benign non-traumatic vertebral compression were included in the study. They received either PAM (1 mg/kg) or synthetic human CT (1.5 mg) as an intravenous infusion. Pain and functional disability were evaluated before infusion, and 4 and 30 days afterwards. The pain score assessed on a visual analogue scale at day 0 was 5.94+/-2.47 in patients treated with PAM and 6.27+/-2.50 in patients treated with CT (p=0.74); at day 4, 4.8+/-2.80 with PAM vs 3.9+/-2.68 with CT (p=0.37); and at day 30, 3.6+/-3.13 with PAM vs 3.10+/-2.76 with CT (p=0.70). Spinal function scores were 18.21+/-3.17 at day 0 in patients treated with PAM vs 17.23+/-4.42 in patients treated with CT (p=0.69) and at day 30, 13.7+/-5.36 with PAM vs 12.33+/-3.22 with CT (p=0.68). We found no advantage of PAM over CT in a single intravenous infusion for the treatment of painful recent benign vertebral compression. Since CT is ten times less costly, its use should be preferred.

Survival of patients with multiple myeloma (MM) showed no improvement between the 1960s and 1990s. During the last decade, new therapeutic approaches seemed likely to offer hope of prolonging survival. The aim of this study was to examine if this survival increased with the usage of new treatments. The method involves a retrospective study of 123 patients with MM, diagnosed between 1975 and 1999, all receiving treatment. They were divided into two groups: group 1 included 55 patients given the so-called "old treatments" [melphalan-prednisone, cyclophosphamide-prednisone, polychemotherapy (vincristine, melphalan, cyclophosphamide, prednisone (VMCP), VMCP-VBAP)], and group 2 included 68 patients receiving at least one of the so-called "new treatments" (dexamethasone, thalidomide, high-dose chemotherapy followed by autotransplants, bisphosphonates, interferon). The two groups were similar in terms of age, sex ratio and renal impairment, and the percentage of light-chain MM was identical in both groups. Patients who had been given a "new" treatment (group 2) had longer median survival than the patients in group 1 (54 vs 42 months). Independent analysis of each treatment modality showed increased median survival in MM patients treated using autotransplantation compared with untreated patients (125 vs 45 months). Survival was also longer in MM patients treated with thalidomide than in untreated patients (72 vs 42 months). On the other hand, neither bisphosphonates, interferon-alpha nor dexamethasone result in improved survival. Our findings emphasize the increased survival of the MM patients treated with new therapeutic approaches.

OBJECTIVE: To determine whether systemic markers of bone, cartilage, and synovium can predict structural progression of osteoarthritis (OA). METHODS: Patients with painful hip OA were treated with diacerein or placebo in a multicentre, prospective, double blind, 3 year follow up trial. The following information was collected at entry: demographics, characteristics of hip OA, and 10 markers: N-propeptides of collagen types I and III, cartilage oligomeric matrix protein, YKL-40, hyaluronan (sHA), matrix metalloproteinases-1 and -3, C reactive protein, C-terminal crosslinking telopeptides of collagen types I and II (uCTX-II). Radiographs were obtained at entry and every year. Structural progression was defined as a joint space decrease > or =0.5 mm or requirement for total hip replacement. Grouped survival analysis was performed with time to structural progression as dependent variable, and clinical data, radiographic findings, treatment groups (diacerein versus placebo), and markers as explanatory measures. RESULTS: In the 333 patients in whom all markers were measured, high functional impairment, a joint space width <2 mm, and lateral migration of the femoral head at baseline increased the risk of progression, but diacerein had a protective effect (relative risk = 0.75; 95% confidence interval (CI) 0.54 to 0.96). In addition, patients in whom uCTX-II and sHA were in the upper tertile had a relative risk of progression of 3.73 (95% CI 2.48 to 5.61) compared with patients with markers in the two lower tertiles. CONCLUSION: In this large cohort, combined measurements of uCTX-II and sHA were a new predictor of the structural progression of hip OA.

OBJECTIVE: To evaluate the level of acceptability of the EULAR recommendations for the management of knee osteoarthritis (KOA) in practice. METHODS: A questionnaire was sent to general practitioners, rheumatologists, rehabilitators, and orthopaedic surgeons in five European countries (France, Spain, Belgium, Switzerland, Italy). Practitioners were asked to give their opinion on the 10 EULAR recommendations and on 23 treatment modes for KOA. Practitioners' opinions were compared with those of the expert task force involved in the development of these recommendations. RESULTS: The overall response rate was 10.4% (4204 replies). Results were similar across countries and specialties. Of the 23 treatment modes proposed, only joint lavage and intra-articular (IA) corticosteroid injections were more strongly recommended by the expert task force than by the responders as a whole, while the opposite was true for spa therapy. Principal component analysis showed: (1) some practitioners preferred "hard line" treatments (surgery, IA injections, or non-steroidal anti-inflammatory drugs (NSAIDs)); (2) there was a difference between those prescribing pharmacological (paracetamol) or non-pharmacological measures with low iatrogenicity (exercises, sticks, education), and those prescribing less well validated treatments closer to "alternative" medicine; (3) each specialist tended to advocate modes that they were most familiar with: rheumatologists were more likely to recommend IA injections and NSAIDs; orthopaedic surgeons, surgical procedures; rehabilitators, education and all non-pharmacological modes; general practitioners, spa therapy and opioids. CONCLUSIONS: A multidisciplinary approach is optimal in the management of this chronic disease with its variable course.

OBJECTIVES: To document adherence to two parts of the EULAR 2000 recommendations for knee osteoarthritis, concerning non-pharmacological and pharmacological first line management; and to identify factors influencing adherence to the recommendations. METHODS: In a prospective study, 1030 randomly selected French general practitioners completed questionnaires about three unselected outpatients with osteoarthritis, and about their own practice, knowledge, and agreement with the EULAR 2000 recommendations. Percentages of adherence of their prescriptions to both parts of the recommendation were calculated, and probabilities of non-adherence analysed in relation to patient and physician related characteristics, using multilevel logistic regression analysis. RESULTS: Data were obtained from 967 physicians and 2430 patients. The EULAR 2000 recommendations were familiar to 79% of the GPs; 99% agreed with the non-pharmacological part and 97% with the pharmacological part. Adherence to the two parts was 74.8% and 73.6%, but 54.2% for both together. Factors increasing adherence to the non-pharmacological recommendation were patient body mass index >35 kg/m(2) (odds ratio 0.11 (95% confidence interval, 0.06 to 0.21)), patient's stated preference for a treatment (OR 0.43 (0.55 to 0.97)), and physician's regular continuance of medical education (OR 0.76 (0.59 to 0.98)); patient's age and duration of symptoms decreased adherence. Factors increasing adherence to the pharmacological recommendation were gastrointestinal disease (OR 0.50 (0.35 to 0.72)) and physician's knowledge of the EULAR recommendations (OR 0.75 (0.60 to 0.93)). CONCLUSIONS: Although most physicians agreed with the EULAR 2000 recommendations, adherence was only approximately 75% for each of the non-pharmacological and pharmacological recommendations and 54% for both together.

OBJECTIVE: To develop evidence based recommendations for the management of hip osteoarthritis (OA). METHODS: The multidisciplinary guideline development group comprised 18 rheumatologists, 4 orthopaedic surgeons, and 1 epidemiologist, representing 14 European countries. Each participant contributed up to 10 propositions describing key clinical aspects of hip OA management. Ten final recommendations were agreed using a Delphi consensus approach. Medline, Embase, CINAHL, Cochrane Library, and HTA reports were searched systematically to obtain research evidence for each proposition. Where possible, outcome data for efficacy, adverse effects, and cost effectiveness were abstracted. Effect size, rate ratio, number needed to treat, and incremental cost effectiveness ratio were calculated. The quality of evidence was categorised according to the evidence hierarchy. The strength of recommendation was assessed using the traditional A-D grading scale and a visual analogue scale. RESULTS: Ten key treatment propositions were generated through three Delphi rounds. They included 21 interventions, such as paracetamol, NSAIDs, symptomatic slow acting disease modifying drugs, opioids, intra-articular steroids, non-pharmacological treatment, total hip replacement, osteotomy, and two general propositions. 461 studies were identified from the literature search for the proposed interventions of efficacy, side effects, and cost effectiveness. Research evidence supported 15 interventions in the treatment of hip OA. Evidence specific for the hip was strikingly lacking. Strength of recommendation varied according to category of research evidence and expert opinion. CONCLUSION: Ten key recommendations for the treatment of hip OA were developed based on research evidence and expert consensus. The effectiveness and cost effectiveness of these recommendations were evaluated and the strength of recommendation was scored.

OBJECTIVES: To update the EULAR recommendations for management of knee osteoarthritis (OA) by an evidence based medicine and expert opinion approach. METHODS: The literature search and guidelines were restricted to treatments for knee OA pertaining to clinical and/or radiological OA of any compartment of the knee. Papers for combined treatment of knee and other types of OA were excluded. Medline and Embase were searched using a combination of subject headings and key words. Searches for those treatments previously investigated were conducted for January 1999 to February 2002 and for those treatments not previously investigated for 1966 to February 2002. The level of evidence found for each treatment was documented. Quality scores were determined for each paper, an effect size comparing the treatment with placebo was calculated, where possible, and a toxicity profile was determined for each treatment modality. RESULTS: 497 new publications were identified by the search. Of these, 103 were intervention trials and included in the overall analysis, and 33 treatment modalities were identified. Previously identified publications which were not exclusively knee OA in the initial analysis were rejected. In total, 545 publications were included. Based on the results of the literature search and expert opinion, 10 recommendations for the treatment of knee OA were devised using a five stage Delphi technique. Based on expert opinion, a further set of 10 items was identified by a five stage Delphi technique as important for future research. CONCLUSION: The updated recommendations support some of the previous propositions published in 2000 but also include modified statements and new propositions. Although a large number of treatment options for knee OA exist, the evidence based format of the EULAR Recommendations continues to identify key clinical questions that currently are unanswered.

OBJECTIVE: To evaluate sex differences in the clinical and structural presentation, and natural history of hip OA. METHODS: A multicentre, prospective, longitudinal, five year follow up study of 508 patients (302 women, 206 men, mean age 63 (7) years) with painful hip OA. Data collected were baseline demographics, symptomatic, therapeutic, and structural variables; symptomatic variables and changes in joint space width (JSW) during the first year's follow up; requirement for total hip arthroplasty (THA) between the end of the first and fifth years. STATISTICAL ANALYSIS: evaluation of sex differences (a) at baseline, in the main characteristics of hip OA using multivariate logistic regression; (b) during the first year of follow up, in the radiological progression of the disease; (c) during the five years of follow up, in the requirement for THA using Kaplan-Meier curves and the log rank test, and of the parameters related to THA, using a multivariate Cox analysis. RESULTS: At entry, women presented more frequently than men with polyarticular OA (mean (SD) articular score 306 (162) v 235 (127)), and superomedial migration of the femoral head (40% v 19%), and had more severe symptomatic disease (patient's overall assessment 46 (23) v 40 (26)). The change in JSW did not differ between women and men after one year, but a greater proportion of women had rapid structural progression (OR=2.34, 95% CI 1.1 to 5.2). THA was performed more often in women. Multivariate analysis suggested that the decision to perform surgery was related more closely to the symptomatic and structural severity of the disease than to the sex of the patient. CONCLUSION: Hip OA in women is more frequently part of a polyarticular OA, and displays greater symptomatic and structural severity.

OBJECTIVE: The links between osteoporosis and arteriosclerosis have been established by numerous epidemiological studies. Could arteriosclerosis induce bone mineral loss via ischemia or other pathological process? We carried out a comparative study of bone mineral density in both legs of patients with unilateral arterial disease of the lower limbs. METHODS: We studied 25 patients, 22 men and 3 women, whose mean age was 62.3 years (range 35-88 years). These patients had unilateral lower limb arterial disease of at least 3 months duration with a systolic index at least 50% lower on the affected than on the healthy side. Bone mineral content (BMC) and bone mineral densities (BMD) of the femoral neck, femur, tibia, foot and ankle of the affected and the unaffected legs were measured by dual x-ray absorptiometry (Lunar DPXL) and the results compared. RESULTS: Bone mineral density was significantly lower in the femur (-3.7%, p = 0.04), the foot and the ankle (-3%, p = 0.05) of the affected leg. There was a non-significant decrease in BMD of the whole femoral neck (-1.2%) and the trochanter (-4.4%, p = 0.08) on the affected side. Tibial bone mineral density was identical in both legs. Bone mineral content was lower on the affected side (-5.3%, p = 0.05) whereas fat mass and muscle mass were the same in both legs. CONCLUSION: The ischemia resulting from arterial disease of the lower limbs appears to have a direct deleterious effect on bone mineralization.

OBJECTIVE: To determine a cut-off point above which a change in joint space width (JSW) could be considered as relevant in patients with hip osteoarthritis (OA) on the basis of predicted need for subsequent total hip arthroplasty (THA). METHODS: A multicentre, prospective, longitudinal, 5-yr follow-up study was performed. A pelvic radiograph was obtained at entry and after 1 and 2 yr. For each film, the narrowest JSW was measured using a 0.1 mm graduated magnifying glass. The absolute and relative differences between baseline and 1 and 2 yr of follow-up were calculated. We determined the cut-off points above which an absolute or relative decrease in JSW between baseline and 1 and 2 yr of follow-up could be considered relevant on the basis of the predicted need for THA during the remaining years of the study. The need for THA was categorized as 'yes' or 'no'. Thereafter, for each observed change in JSW (0.1 per 0.1 mm or 1% per 1%), the sensitivity and specificity for subsequent THA were calculated. The choice of cut-off was based on maximal sensitivity and specificity, using the graphic representation of correct classification probabilities. In this way it was possible to obtain the best measured JSW threshold with maximal true positive and minimal false positive results. RESULTS: A total of 423 and 385 patients met the criteria for analysis using the decrease in JSW between baseline and 1 and 2 yr respectively. The best cut-off points were absolute decreases in JSW of 0.2 and 0.4 mm and relative decreases in JSW of 15 and 20% after 1 and 2 yr respectively, with corresponding ranges of sensitivity and specificity of 68-75 and 67-78%. CONCLUSION: This work determined the cut-off above which a change in JSW could be considered clinically relevant in patients with hip OA, on the basis of predicted subsequent need for THA. For validation, similar studies should be conducted in other countries with different health-care systems.
