Epidemiology of Paget's disease in Europe: the prevalence is decreasing.

UNLABELLED: This study estimated changes in the age- and sex-specific prevalence of Paget's disease of bone in six European towns over a 20-year period. Declines in prevalence were observed in this disorder, occurring among both men and women. INTRODUCTION: To estimate secular changes in the age-and sex-specific prevalence of Paget's disease of bone in Europe, we conducted a second radiographic survey using identical sampling and methods in six European towns where a baseline study was performed in 1978-1979. In addition to these towns, the survey was carried out in two Hungarian centers not included in the initial study. MATERIALS AND METHODS: In each center, a sample of abdominal radiographs of people >or=55 years of age was taken from stored films within the radiology department of the principal general hospital. Radiographs showing the entire pelvis, sacrum, femoral heads, and lumbar vertebrae were studied for the period of 2000-2001. The films were evaluated by a trained observer and a consultant radiologist. RESULTS: A total of 6935 radiographs (3512 women and 3423 men) were assessed in the eight towns. The overall age- and sex-standardized prevalence rate of Paget's disease was 0.3% with a male/female ratio of 1.5. Prevalence increased with age among men and women rising to 0.8% of men and 0.9% of women >/=85 years of age. The differences in prevalence rate among the European centers were relatively small, especially in women. There was a decline in rates between 1978/79 and 2000/01. CONCLUSIONS: These European data confirm the decrease in frequency of Paget's disease observed in Britain. These declines favor an environmental contribution to the causation of the disease that requires further research.

Coexistent Marfan's syndrome and ankylosing spondylitis.

We describe a 22-year-old woman with coexisting Marfan's syndrome (MFS) and ankylosing spondylitis (AS). A change of fibrillin-1 due to mutation of the FBN1 gene (MFS) or a cell-mediated autoimmune response in AS could account for a common pathology.

Detection of TT virus in patients with idiopathic inflammatory myopathies.

The TT virus, a recently identified single-stranded DNA virus with unknown pathogenicity, has been shown to commonly infect humans. Viruses have been considered to contribute to disease pathogenesis in autoimmune disorders including idiopathic inflammatory myopathies (IIMs) and rheumatoid arthritis (RA). We assessed the prevalence of TTV infection in IIM compared with that in patients with RA and healthy blood donors. Detection of TTV was conducted by nested PCR and real-time PCR in the sera of 94 patients with IIM, 95 RA patients. and 95 age- and sex-matched healthy blood donors. Identity of the PCR products was confirmed by sequencing. TTV DNA was detected in 61 of 94 (64.9%) patients with IIM, in 64 of 95 (67.4%) patients with RA, and in 62 of 95 (65.3%; P > 0.05) healthy individuals. Age, sex, activity, or duration of disease had no influence on TTV positivity in either group. However, patients with severe IIM (n = 36) had a significantly higher rate of TTV infection (31/36, 86.1%) than patients with mild disease (30/58, 51.7%, P < 0.05, chi(2) = 10.0). Disease was considered severe in IIM when immunosuppressive treatment was necessary because of continuous high activity and/or serious inner-organ involvement despite corticosteroid treatment. In conclusion, although we found the detection rate of TTV similar in patients with idiopathic inflammatory myopathies and rheumatoid arthritis and comparable to that in healthy controls, our data suggest that infection with TT virus may result in a more severe disease in patients with idiopathic inflammatory myopathies.

Efficacy and safety of four doses of lumiracoxib versus diclofenac in patients with knee or hip primary osteoarthritis: a phase II, four-week, multicenter, randomized, double-blind, placebo-controlled trial.

OBJECTIVE: To compare the efficacy and tolerability of the novel cyclooxygenase 2-selective inhibitor lumiracoxib with placebo and diclofenac in osteoarthritis (OA). METHODS: Adults (n=583) with knee or hip OA were randomized to receive for 4 weeks lumiracoxib 50, 100, or 200 mg twice daily or 400 mg once daily; placebo; or diclofenac 75 mg twice daily. Efficacy assessments included overall joint pain intensity and Western Ontario and McMaster Universities Osteoarthritis Index subscales; tolerability was evaluated by adverse event and physician reporting. RESULTS: All lumiracoxib doses were superior to placebo in relieving pain, improving stiffness, and improving physical function after 4 weeks. At study endpoint, pain relief was comparable among all lumiracoxib dosages and similar to diclofenac. Lumiracoxib tolerability was superior to diclofenac and comparable to placebo. CONCLUSION: Lumiracoxib provides predictable and sustained relief from pain, stiffness, and impaired physical function in OA. Lumiracoxib shows clinically comparable efficacy and superior tolerability to diclofenac.

Relapsing polychondritis.

Relapsing polychondritis (RP) is a rare multisystem autoimmune disease of unknown origin characterized by recurrent episodes of inflammation and progressive destruction of cartilaginous tissues. Elastic cartilage of the ears and nose, hyaline cartilage of peripheral joints, vertebral fibrocartilage and tracheobronchial cartilage, as well as proteoglycan-rich structures of the eye, heart, blood vessels or inner ear may all be affected. In most patients RP manifests in a fluctuating but progressive course which eventually results in a significant shortening of life expectancy. The relatively uncommon occurrence, the unknown etiopathogenesis, the ambiguous clinical pattern, as well as the variety in its course and response to therapy may all contribute to the difficulties the physician must overcome when managing RP. Beside describing the main features of RP and seven clinical cases of our own, in the present review we focus on recent findings in the etiopathogenesis and novel treatment options.

Atypical form of active melorheostosis and its treatment with bisphosphonate.

We present the case of a 38-year-old man in whom extensive bilateral melorheostosis was associated with elevated serum alkaline phosphatase, swelling of the right foot and progressive deformity of the left hand, left leg and right foot. Radiography, computed tomography and bone scintigraphy were performed. Following treatment with bisphosphonate (30 mg/day of pamidronate for 6 days) infusion, the pain and swelling of his right foot showed improvement and his elevated serum alkaline phosphatase decreased.

[Prognostic factors in rheumatoid arthritis].

Rheumatoid arthritis is a chronic, progressive, inflammatory joint disease, affecting primarily the small joints of the hands and feet symmetrically and characterized by joint destruction, progressive disability, and premature death. Rheumatoid arthritis shows a wide spectrum of clinical phenotypes from mild disease to severe arthritis. Aggressive disease implies a rapidly progressive course affecting most joints, with little or no response to drug therapy, and sometimes complicated by life-threatening extraarticular involvement. The eventual multiple joint destruction requires major surgery, and severe disability results in loss of occupation and dependence on others. Many prospective cohort studies have attempted to predict outcomes and develop prognostic markers, especially in early disease. Probably most useful are those factors that independent of disease activity, such as the presence of rheumatoid factor, the so-called shared epitope of HLA-DR. In addition, clinical indicators (e.g., higher affected joint counts, the presence of extra-articular features, subcutaneous nodules, considerable degree of physical disability at onset), laboratory variables (e.g., longstanding increased acute-phase response, decreased hemoglobin) are indicating a poor prognosis. Some sociodemographic markers, such as female sex and a lower level of formal education are associated with a poor prognosis. An ideal prognostic marker should be reliable, simple, accurate and independent of the stage and inflammatory activity of RA so that they can be used early of the disease. Patients with a poor outcome should be treated promptly and aggressively with disease-modifying antirheumatic drugs to limit or prevent further disease progression.
