    ABSTRACT: PurposeWe review the current knowledge about fibromyalgia, adding to the clinical aspects, the nosology, epidemiology and pathogenesis. The therapeutic and social management of these suffering patients are discussed.Key pointsThe limitations of the American College of Rheumatology classification criteria used as diagnostic criteria are discussed. Fibromyalgia is not a simple psychiatric disorder, even if psychiatric symptoms are constantly found. Based on functional brain imaging, there is some evidence pointing to an abnormal function of the supra-spinal centres for pain regulation.Conclusion Fibromyalgia is a clinical autonomous entity. Physiopathology knowledge is improving, but must be confirmed by new research. Patients will take profit of multimodal individualized treatment programs, including explanations about the diagnosis. In most cases, fibromyalgia is compatible with the maintenance of a professional activity, possibly adapted to the patient. Recognized disability requiring compensation is infrequent.

    ABSTRACT: The Group for the Respect and Excellence in Science (GREES) has reviewed and updated their recommendations for clinical trials to evaluate the efficacy and safety of new chemical entities to be used in the treatment and prevention of glucocorticoid-induced osteoporosis (GIOP). Consensus discussion of the committee. With the exception of steroid use posttransplantation, there is no need to differentiate between underlying diseases. Prevention and treatment for GIOP are dependent on exposure to glucocorticoids rather than T-scores as in postmenopausal osteoporosis (PMO). If fracture data are obtained for PMO, it need not be repeated for GIOP, relying instead on bone mineral density (BMD) trials of at least 1 year. GREES recommends several changes in the previous guidance for GIOP. The committee saw no need to repeat preclinical studies if those have been previously done to assure bone quality in PMO. Similarly, phase I and phase II trials, if careful dose selection has been done for PMO, should not be repeated. The "prevention" and "treatment" claims should remain. Since the most recent evidence suggests significant increase in fracture risk for daily doses of prednisone of 5 mg/day or equivalent, clinical trials should concentrate on patients receiving at least this daily dosage. The emergence of bisphosphonates as the reference treatment, together with the rapid bone loss and high fracture incidence in glucocorticoid users, necessitates recommending a noninferiority trial design with lumbar spine BMD as the primary endpoint after 1 year. Registration of new chemical entities to be used in the management of GIOP should be granted, based on a 1-year noninferiority trial, using BMD as primary outcome and alendronate or risedronate as comparator. Demonstration of antifracture efficacy should have been previously demonstrated in PMO.

    ABSTRACT: The Group for the Respect of Ethics and Excellence in Science (GREES) organized a working group to assess the value of time to joint surgery as a potential therapeutic failure outcome criterion for osteoarthritis (OA) of the hip or knee in the assessment of potential structure modifying agents. PubMed was searched for manuscripts from 1976 to 2004. Relevant studies were discussed at a 1-day meeting. There are no accepted guidelines for 'time to' and 'indications for' joint replacement surgery. A limited number of trials have examined joint replacement surgery within the study population. Several parameters, particularly joint space narrowing (interbone distance), correlate with surgical intervention. However, at the level of the knee, none of the parameters have positive predictive value for joint replacement surgery better than 30%. In contrast, lack of significant joint space narrowing has a strong negative predictive value for joint replacement surgery (>90%), that remains after controlling for OA pain severity. At this time, GREES cannot recommend time to joint surgery as a primary endpoint of failure for structure modifying trials of hip or knee OA-as the parameter has sensitivity but lacks specificity. In contrast, in existing trials, a lack of progression of joint space narrowing has predictive value of >90% for not having surgery. GREES suggests utilizing joint space narrowing (e.g., >0.3-0.7 mm) combined with a lack of clinically relevant improvement in symptoms (e.g., >/=20-25%) for 'failure' of a secondary outcome in structure modifying trials of the hip and knee.

    ABSTRACT: Polyarteritis nodosa is a rare life-threatening disease characterized by necrotizing vasculitis of small and median arteries. We describe the exceptional case of a 28-year-old man with successive spontaneous visceral hematomas of the kidney, bladder, and liver. Arteriography was performed for a recent spontaneous hepatic hematoma and a microaneurysm was detected, allowing the diagnosis of polyarteritis nodosa and prescription of appropriate treatment.

    ABSTRACT: There is still debate on whether inflammatory pseudotumor should be considered benign or malignant. This lesion has only been reported twice in bone, apart from cases complicating foreign body reaction to joint replacement arthroplasty. We report here a third case, localized at the sacrum. A 31-year-old man had inflammatory dorsalgia and polyarthralgia without synovitis but with fever, asthenia, and erythema nodosa. Biological tests and X-rays were not informative, but technetium scintigraphy revealed a high level of left sacroiliac tracer binding. Several nonsteroidal anti-inflammatory drugs and sulfasalazine treatment were given over 3 months but ineffective. Pelvic magnetic resonance imaging showed an osteolytic tumor of the sacrum. Biopsy suggested a malignant fibrosarcoma, but complete evaluation after surgical resection demonstrated an inflammatory pseudotumor. All clinical symptoms disappeared within a few days after surgery, which is suggestive of a paraneoplastic syndrome. No relapse has occurred after 4 years.

    ABSTRACT: Intra-articular injection of 169Erbium-citrate (169Er-citrate; radiosynoviorthesis or radiosynovectomy) is an effective local treatment of rheumatic joint diseases. However, its efficacy in corticosteroid-resistant rheumatoid arthritis-affected joints has not been clearly demonstrated. A double-blind, randomised, placebo-controlled, international multicentre study was conducted in patients with rheumatoid arthritis with recent (< or = 24 months) ineffective corticosteroid injection(s) into their finger joint(s). Eighty-five finger joints of 44 patients were randomised to receive a single injection of placebo (NaCl 0.9%) or 169Er-citrate. Results of evaluation 6 months later were available for 82 joints (46 metacarpophalangeal and 36 proximal interphalangeal joints) of 42 patients: 39 169Er-citrate-injected joints and 43 placebo-injected joints. Efficacy was assessed using a rating scale for joint pain, swelling and mobility. Intent-to-treat analysis of the results of the 82 joints showed a significant effect of 169Er-citrate compared to placebo for the principal criteria decreased pain or swelling (95 vs 79%; p = 0.038) and decreased pain and swelling (79 vs 47%; p = 0.0024) and for the secondary criteria decreased pain (92 vs 72%; p = 0.017), decreased swelling (82 vs 53%; p = 0.0065) and increased mobility (64 vs 42%; p = 0.036). Per-protocol analysis, excluding 18 joints of patients who markedly changed their usual systemic treatment for arthritis, gave similar percentages of improvement but statistical significance was lower owing the reduced power of the statistical tests. These results confirm the clinical efficacy of 169Er-citrate synoviorthesis of rheumatoid arthritis-diseased finger joints after recent failure of intra-articular corticotherapy.

    ABSTRACT: The aim of this study was to compare the effects on NO production of IL-4, IL-10, and IL-13 with those of TGF-beta. RA synovial cells were stimulated for 24 h with IL-1 beta (1 ng/ml), TNF-alpha (500 pg/ml), IFN-gamma (10(-4)IU/ml) alone or in combination. Nitrite was determined by the Griess reaction, S-nitrosothiols by fluorescence, and inducible NO synthase (iNOS) by immunofluorescence and fluorescence activated cell sorter analysis (FACS). In other experiments, IL-4, IL-10, IL-13, and TGF beta were used at various concentrations and were added in combination with proinflammatory cytokines. The addition of IL-1 beta, TNF-alpha, and IFN-gamma together increased nitrite production: 257.5 +/- 35.8 % and S-nitrosothiol production : 413 +/- 29%, P < 0.001. None of these cytokines added alone had any significant effect. iNOS synthesis increased with NO production. IL-4, IL-10, IL-13, and TGF beta strongly decreased the NO production caused by the combination of IL-1 beta, TNF-alpha, and IFN-gamma. These results demonstrate that stimulated RA synoviocytes produce S-nitrosothiols, bioactive NO* compounds, in similar quantities to nitrite. IL-4, IL-10, IL-13, and TGF-beta decrease NO production by RA synovial cells. The anti-inflammatory properties of these cytokines may thus be due at least in part to their effect on NO metabolism.

    ABSTRACT: Physical and biological dosimetry were investigated in 45 rheumatoid arthritis patients treated by radiosynoviorthesis (RSO) with 186Re-sulphide (medium-sized joints) and 169Er-citrate (digital joints). Biological dosimetry involved scoring dicentrics in lymphocytes, cultured from blood samples withdrawn just before and 6 h, 24 h and 7 days after treatment. Physical methods included repeated blood sample counts and scintigraphy data. For erbium-169 (pure beta emitter), only bremsstrahlung could be measured and solely in the injection area. For rhenium-186 (both beta and gamma emitter), whole body scans and static images of joints and locoregional lymph nodes were performed. Dosimetry calculations were in accordance with the MIRDOSE 3 software and tables. For erbium-169 (21 patients), either metacarpophalangeal (30 MBq) or proximal interphalangeal (20 MBq) joints of the hands were treated (one joint per patient); 18 patients (out of 21) were interpretable for biological dosimetry, 10 (out of 11) for physical dosimetry and six (out of 10) for both. For rhenium-186, 23 wrists, nine elbows, three shoulders and two ankles were injected in 24 patients, with a maximum of three joints per patient (70 MBq per joint); 20 patients (out of 24) and 10 (out of 10) were interpretable for biological and physical dosimetry, respectively, and eight (out of 10) for both methods. Erbium-169 biological dosimetry was negative in all interpretable patients, and physical dosimetry gave a blood dose of 15 +/- 29 microGy and an effective dose lower than 1 mSv/30 MBq. For rhenium-186, biological results were negative in 16 patients (out of 20), but showed a blood irradiation around 200 mGy in the last four. A significant cumulative increase of dicentrics 7 days after injection (16/10,000 instead of 5/10,000 prior to treatment; p < 0.04) was also noted. Gamma counts gave a blood dose of 23.9 +/- 19.8 mGy/70 MBq and the effective dose was found to be 26.7 +/- 5.1 mGy/70 MBq, i.e. about 380 microGy.MBq-1. Erbium-169 RSO is very safe from both physical and biological dosimetry standpoints. Rhenium-186 leak is greater, as demonstrated by the higher blood activity and the measurable, although limited, dicentrics induction in blood lymphocytes. However, the effective dose remains moderate, i.e. 30 times lower than in 131I therapy in benign thyroid diseases.

    ABSTRACT: Dactylitis and calcaneitis developed in a patient with untreated sarcoidosis of the skin and lungs. Radiographs showed a defect in the second phalanx of the left middle finger. Radiographs of the feet were normal, but magnetic resonance imaging demonstrated a defect in the left calcaneus. Methylprednisolone therapy (1 g per day for 3 consecutive days) induced a dramatic improvement within 48 hours. Low-dose oral glucocorticoid therapy was given subsequently. One year later, a recurrent episode of dactylitis responded promptly to the same regimen. Maintenance therapy was given, and no further recurrences were noted during the four-year follow-up. Sarcoid bone lesions are uncommon and arise selectively in the small bones of the hands and feet. Involvement of the calcaneus is exceedingly rare, and its treatment is not standardized. In our patient, glucocorticoid therapy combined with methotrexate and hydroxychloroquine were effective in controlling the disease.

    ABSTRACT: Nitric oxide (NO degrees ) is a free molecule produced by NO synthases which acts as a mediator in inflammatory processes. NO degrees can react with thiol groups of proteins to produce nitrosothiols. Increased concentrations of these bioactive compounds have been found in sera and synovial fluids from patients with osteoarthritis (OA). The aim of this study was to assess the ability of human osteoarthritic chondrocytes to synthesize nitrosothiols and to compare the in vitro effects of rhein, cortisol and diclofenac on nitrosothiol and nitrite production. Osteoarthritic chondrocytes were incubated for 24 h with 1 ng/ml of recombinant human interleukin-1beta (IL-1beta) in the presence or absence of rhein (1.3x10(-5) M, 6.5x10(-6) M, or 1.3x10(-6) M), cortisol (10(-5) M) or diclofenac (10(-5) M or 10(-6) M). Nitrite levels were measured in cell supernatants by the Griess method; nitrosothiol levels were determined in supernatants and cellular lysates by fluorimetry. At the basal level, nitrosothiols represented 80% of the total of nitrite and nitrosothiol production. After IL-1beta stimulation, NO degrees production was highly increased in the supernatants (45-fold increase in nitrite, 60-fold increase in nitrosothiols) as well as in cell lysates (35-fold increase in nitrosothiols). Rhein caused a dose-dependent decrease in nitrosothiol and nitrite production. In comparison, diclofenac (10(-5) M) moderately decreased nitrite and nitrosothiol levels in the supernatants but had no effect on lysate nitrosothiol. Cortisol had no significant effect on NO degrees production. The IL-1beta stimulation increased nitrosothiol production by osteoarthritic chondrocytes. These results demonstrate the need to measure nitrosothiol as well as nitrite production. Rhein inhibited the IL-1beta induced NO degrees production, and may be a suitable treatment for osteoarthritis.

    ABSTRACT: We investigated nitric oxide (NO) production and inducible NO synthase (iNOS) expression by cultured peripheral blood mononuclear cells (PBMC) in systemic sclerosis (SSc). Eighteen patients with SSc were compared to two control groups: 16 rheumatoid arthritis patients (RA) and 23 mechanical sciatica patients. The sum of nitrites and nitrates was determined by fluorimetry in sera and spectrophotometry in supernatants. Inducible iNOS was detected in cultured PBMC by immunofluorescence, immunoblot and flow cytometry with or without IL-1 beta + TNF alpha, IL-4 or IFN gamma from day 1 to day 5. NO metabolite concentrations in the plasma were lower in SSc (34.3 mumol/l +/- 2.63 SEM) than in RA (48.3 mumol/l +/- 2.2; p < 0.02) and sciatica (43.3 mumol/l +/- 5.24; p < 0.03) patients. iNOS was detected in cultured monocytes in the 3 groups but induction occurred on day 1 in RA, day 2 in sciatica and only on day 3 in SSc, whatever the stimulus. The concentrations of NO metabolites are decreased in SSc patients and the induction of iNOS in PBMC is delayed. Low levels of NO, a vasodilator, may be involved in vasospasm, which is critical in SSc. This may suggest therapeutic implications.

    ABSTRACT: To determine the cumulative incidence and the point prevalence of atopy in patients with rheumatoid arthritis (RA). A standardized questionnaire was sent to 300 RA patients. Questions concerned previous or present characteristics of atopy (hay fever, asthma and constitutive eczema) and RA. RA patients were matched with genetically unrelated controls (sister- or brother-in-law, neighbour or friend). The same questionnaire (except for questions about RA) was sent to the control subjects. In cases of atopy, patients, controls and the treating physicians were contacted by a physician to check the validity of the responses. Paired responses were obtained in 173 cases. Information about atopy was obtained for 69 other RA patients. The characteristics of RA were similar for patients who responded and those who did not respond. The frequency of atopy was significantly lower in RA patients than in controls, both for cumulative incidence (RA 7.5%, controls 18.8%; P: < 0.01) and point prevalence (RA 3.5%, controls 16.2%; P: < 0.0001). The clinical manifestations of atopy stopped before the onset of RA in eight of the 17 RA patients with an allergic condition, and there was no subsequent relapse. No effect of RA treatment could account for the remission of atopy. These data support the concept that atopy protects against the future development of RA and that the two diseases could counterbalance one another.

    ABSTRACT: To evaluate the efficacy of upper cervical spine surgery in symptomatic atlantoaxial instability due to rheumatoid arthritis (RA). Thirty RA patients (29 women and one man) with a mean age of 56 years were studied retrospectively. Symptomatic forward slippage of the atlas on the axis with a synovial pannus surrounding the odontoid and magnetic resonance imaging evidence of spinal cord compression was present in all 30 patients; 18 patients had vertical translocation of the odontoid and 14 had basilar invagination. Surgery, performed between 1991 and 1997, consisted of occipitocervical fusion in 18 patients and atlantoaxial fusion in 12. Cotrel-Dubousset instrumentation was performed in all 30 patients. Mean follow-up was four and a half years. All patients were satisfied with the procedure and exhibited marked functional gains and objective neurological improvement (by one class in the Ranawat scheme). Stable fusion was documented in all 30 patients. Cervical instrumentation and bone grafting seems to provide functional and neurological gains in carefully selected RA patients with atlantoaxial instability and spinal cord compression. Long term follow-up suggests that the benefits are sustained and that morbidity is low.

    ABSTRACT: To investigate the expression of inducible nitric oxide synthase (iNOS) in subpopulations of peripheral blood and synovial fluid (SF) leukocytes in patients with rheumatoid arthritis (RA). iNOS was detected in peripheral blood and SF samples after cell permeabilization, by 2 color immunofluorescence flow cytometry. Samples from 14 patients with RA and 8 with osteoarthritis (OA) were studied. Nitrite concentration was determined by Griess reaction, interleukin 1beta and tumor necrosis factor alpha by an immunoenzymatic assay, and C-reactive protein (CRP) by an immunonephelometric method. In SF, iNOS was detected in 11 of 14 patients with RA and 2 of 8 with OA. In blood cells, iNOS was detected in 8 of 14 patients with RA and none of the OA group. iNOS was consistently detected in monocytes and was not detected in granular cells. In RA, there was no correlation between the number of iNOS positive mononuclear cells and cytokine concentrations. CRP concentration was correlated with the number of iNOS positive mononuclear cells in RA SF samples. SF mononuclear cells from patients with RA express iNOS and are involved in NO production in the joint. The number of positive cells is correlated with CRP concentration, suggesting the implication of NO production in the inflammatory process.

    ABSTRACT: To evaluate articular involvement in a large cohort of patients with thromboangiitis obliterans (TAO). A retrospective chart review of all patients with TAO admitted to our rheumatology or vascular medicine departments between 1975 and 1995 was undertaken. Patients with a history of osteoarticular involvement were further investigated. This evaluation entailed taking a detailed rheumatologic and musculoskeletal history and physical examination. Laboratory tests and osteoarticular radiographs were obtained. Initial rheumatic manifestations were observed in 11 (12.5%) (7 male/4 female) of 83 (71 male/12 female) patients with TAO. Eight patients presented recurrent episodes of arthralgia, which preceded the diagnosis of TAO by 2 to 13 years (median 10 years). The episodes were monoarticular, acute, transient, and migratory, affected large joints with local inflammatory signs, and were nonerosive. The initial diagnosis often referred to a loco-regional or periarticular problem that tended to recur. There was permanent disappearance of these prodromal rheumatic features with the appearance of ischemic features. Two patients had HLA-B27+ undifferentiated spondyloarthropathies and one presented oligoarthritis. TAO should be considered in patients presenting intermittent rheumatism. The key symptoms and signs of the disease should be monitored during the followup period because the first occlusive features may appear more than 10 years later. Thromboangiitis manifestations can thus be similar to systemic vasculitis and connective tissue disease. If the patient is a young adult smoker, particularly a young man with diminished or absent distal pulses, a diagnosis of TAO should be considered.
