Objective: To determine the prevalence of generalized osteoarthritis in patients with knee osteoarthritis. Methods: Patients with knee osteoarthritis were recruited for a therapeutic trial via press announcement and selected based on American College of Rheumatology radioclinical criteria for femorotibial arthritis. Patients were asked to bring all their radiographs to the study visits, which included a physical examination. Each patient had an inclusion visit and a second visit 1 month later. The study physicians used a standardized chart to indicate clinical and radiographic evidence of osteoarthritis in each patient. At the hands and feet, the presence of clinical criteria was sufficient for the diagnosis of osteoarthritis. The shoulders and elbows were not assessed. Three criteria sets for generalized osteoarthritis were evaluated: Kellgren and Moore criteria (Heberden's nodes or interphalangeal osteoarthritis), ACR criteria (osteoarthritis of the spine and at least two other joints), and Dougados criteria (bilateral finger osteoarthritis or osteoarthritis of the spine and both knees). Results: We included 302 patients for whom the side affected with knee osteoarthritis was known. Mean symptom duration was 5.9±5.7 years, mean number of painful flares was 10.1±9.4, mean number of joints with osteoarthritis was 2.6±1.8, and mean body mass index was 29.5±5.3kg/m2. A family history of osteoarthritis was noted in 154 (51%) patients and spinal osteoarthritis in 148 (49%) patients. Kellgren-Moore criteria for interphalangeal osteoarthritis were met in 42 (13.9%) patients, ACR criteria by 124 (41%) patients, and Dougados criteria by 127 (42%) patients. In all, 156 (52%) patients met at least one of the three definitions of generalized osteoarthritis. Conclusion: More than half the patients included in a therapeutic trial in knee osteoarthritis had generalized osteoarthritis with maximum symptoms at the knee at baseline. Some patients with osteoarthritis in multiple joints met none of the three criteria sets for generalized osteoarthritis. Further studies are needed to assess the sensitivity and specificity of current criteria sets and, if needed, to identify new criteria. © 2009 Société française de rhumatologie.

Gout is the most common inflammatory arthritis and one in which pathogenesis and risk factors are best understood. One of the treatment objectives in current guidelines is 'cure'. However, audits show that only a minority of patients with gout receive adequate advice and treatment. Suboptimal care and outcomes reflect inappropriately negative perceptions of the disease, both in patients and providers. Historically, gout has been portrayed as a benign and even comical condition that is self-in flicted through overeating and alcohol excess. Doctors often focus on managing acute attacks rather than viewing gout as a chronic progressive crystal deposition disease. Urate-lowering treatment is underprescribed and often underdosed. Appropriate education of patients and doctors, catalysed by recent introduction of new urate-lowering treatments after many years with no drug development in the field, may help to overcome these barriers and improve management of this easily diagnosed and curable form of potentially severe arthritis.

The anti-CD20 antibody rituximab has been reported to induce a heterogeneous spectrum of lung disorders. The aim of the present study was to critically review data on the clinical presentations, causality assessments and management strategies of lung diseases possibly related to rituximab. A systematic literature review was performed on English-language reports in PubMed until September 2008. Cases of lung diseases ascribed to rituximab (n=45) were identified, with three time-to-onset patterns. The most common presentation was acute/subacute hypoxaemic organising pneumonia (n=37), starting 2 weeks after the last infusion (often around the fourth cycle) and resolving, in most cases, provided glucocorticoid therapy was given early. Acute respiratory distress syndrome occurred in five patients, within a few hours and usually after the first infusion. In the remaining three patients, macronodular organising pneumonia developed insidiously long after rituximab therapy and responded to steroids. Eight patients died. Based on time to onset, symptoms, and responses to discontinuation and rechallenge with rituximab and other drugs, 13 cases were highly compatible and 32 compatible with rituximab-induced lung disease. Knowledge of these presentations of rituximab-induced lung disease should prove helpful for diagnosis and causality assessment purposes. Time-to-onset data, suggesting different pathogenic mechanisms, support closer clinical and perhaps radiological monitoring between infusions, particularly in patients with a history of reversible respiratory symptoms.

In chronic kidney disease the excessive production of parathyroid hormone increases the bone resorption rate and leads to histologic bone signs of secondary hyperparathyroidism. However, in other situations, the initial increase in parathyroid hormone and bone remodeling may be slowed down excessively by a multitude of factors including age, ethnic origin, sex, and treatments such as vitamin D, calcium salts, calcimimetics, steroids, and so forth, leading to low bone turnover or adynamic bone disease. Both high and low bone turnover diseases actually are observed equally in chronic kidney disease patients treated by dialysis, and all types of renal osteodystrophy are associated with an increased risk of skeletal fractures, reduced quality of life, and poor clinical outcomes. Unfortunately, the diagnosis of these bone abnormalities cannot be obtained correctly by current clinical, biochemical, and imaging methods. Therefore, bone biopsy has been, and still remains, the gold standard analysis for assessing the exact type of renal osteodystrophy. It is also the unique way to assess the mechanisms of action, safety, and efficacy of new bone-targeting therapies. © 2014 Elsevier Inc.

Objective: To describe the hospital burden of microcrystal arthropathies in France. Methods: Data were extracted from the 2009-2011 French hospital national databases. We selected all hospital stays for microcrystal arthropathies (gout, chondrocalcinosis, other) encoded as primary or secondary diagnoses in patients older than 18. A descriptive analysis focused on number of patients and hospital stays, age, gender, comorbidities related to metabolic syndrome, and hospital costs based on 2012 public-sector costs. Results: 132,275 hospitalizations involving 109,734 patients were related to microcrystal arthropathies encoded as primary or secondary diagnosis (61% related to gout, 34% to chondrocalcinosis, and 5% to other microcrystal arthropathies). 23,362 hospitalizations involving 25,105 patients were due to microcrystal diseases, encoded as primary diagnosis, (48% related to gout, 43% to chondrocalcinosis, and 9% to other microcrystal arthropathies). In this population, patients with chondrocalcinosis were older (mean 75.6 ± 13.5 versus 71 ± 16 years for other microcrystal arthropathies and 69.7 ± 14.7 for gout). Men represented 70% of the patients with gout, 39% of those with chondrocalcinosis and 52% of the patients with other microcrystal arthropathies. Hypertension, diabetes, dyslipidemia, cardiac ischemia, and renal failure were more frequent in patients with gout than other patients. The hospital costs for microcrystal arthropathies encoded as primary diagnosis were 82.3 million Euros, 45% related to gout, 45% to chondrocalcinosis and 11% to other microcrystals. Conclusion: In terms of hospital costs, gout and chondrocalcinosis represented the main part of the economic burden of crystal arthropathies and a high level of diseases belonging to the metabolic syndrome. Specific education programs favouring accurate microcrystal diagnosis and adherence to treatment could diminish this hospital economic burden. © 2015 Société française de rhumatologie.
