15251134 | Interleukin-15: a new cytokine target for the treatment of inflammatory diseases. | 2004 Aug | Interleukin (IL)-15 is a pleiotropic pro-inflammatory cytokine that is expressed in several inflammatory disorders, including rheumatoid arthritis, psoriasis and pulmonary inflammatory diseases. IL-15 promotes activation of T cells, neutrophils and macrophages, and is critical to dendritic cell function in several model systems. Recent emerging data suggest that IL-15 may serve as a useful therapeutic target across a range of disease states. Advances in the past year highlight the beneficial effect of IL-15 neutralisation in models of psoriasis and diabetes. Further evidence for IL-15 expression and effector function has emerged across a range of rheumatic disorders, including juvenile inflammatory arthritis, rheumatoid arthritis and Kawasaki disease. These data hold promise for therapeutic targeting in ongoing human studies and those in the near future. | |
14979940 | A randomized, controlled trial of interferon-beta-1a (Avonex(R)) in patients with rheumato | 2004 | The objective of this study was to evaluate the safety and possible efficacy of IFN-beta-1a for the treatment of patients with rheumatoid arthritis (RA). Twenty-two patients with active RA were enrolled in a phase II randomized, double-blind, placebo-controlled trial of 30 microg IFN-beta-1a by weekly self-injection for 24 weeks. The primary outcome of the study was safety. Secondary outcomes included the proportion of patients achieving an American College of Rheumatology (ACR) 20 response at 24 weeks. There were no significant differences in adverse events reported in the two groups. Fewer than 20% of patients in each arm of the study achieved an ACR 20 response at 24 weeks (P = 0.71). Sixty-nine percent of patients receiving IFN-beta and 67% receiving placebo terminated the study early, most of them secondary to a perceived lack of efficacy. Overall, IFN-beta-1a had a safety profile similar to that of placebo. There were no significant differences in the proportion of patients achieving an ACR 20 response between the two groups. | |
12558781 | Treatment of chronic haemophilic synovitis in humans with D-penicillamine. | 2003 Jan | Chronic proliferative synovitis secondary to haemathroses is a major complication in patients with severe haemophilia. Current management strategies include prophylactic infusions of the missing coagulation factor, corticosteroids, synoviorthesis and/or synovectomy with variable degrees of benefit. In addition, patients with coagulation factor inhibitors are not amenable to the invasive therapeutic modalities. The gross and microscopic findings of the synovitis in haemophilic arthritis are remarkably similar to those seen in patients with rheumatoid arthritis, although the pathophysiology of these two conditions are quite different. Haemophilic arthropathy, in the later stages, resembles degenerative rather than inflammatory joint disease. Oral D-penicillamine, a drug effective in the proliferative synovitis of rheumatoid arthritis, was evaluated in 16 patients. Ten patients had an unequivocal response, while three had a reduction in palpable synovium and three had no response. Thus 81% of the patients had a beneficial response. Minor reversible drug side-effects occurred in two patients (proteinuria in one and a rash in the second). The results of this study suggest that D-penicillamine is an effective and safe drug for the treatment of haemophilic chronic synovitis. | |
12108757 | Current issues in Sjögren's syndrome. | 2002 May | Sjögren's syndrome is a chronic autoimmune and rheumatic disorder with prominent sicca complaints from the mucous membranes because of lack of proper exocrine secretions. There is no straightforward and simple diagnostic test for Sjögren's syndrome, although several classification criteria have been designed including several oral diagnostic tests. A new set of classification criteria in a joint effort by research groups in Europe and USA has recently been presented. A large number of autoantibodies have been reported in Sjögren's syndrome where, in some cases, the antibodies are correlated with the extent and severity of disease. The finding of serum autoantibodies directed against the muscarinic M3 receptor is an important advance in understanding the pathogenesis of not only the impaired glandular function but also associated features of autonomic dysfunction in some patients. The treatment of primary Sjögren's syndrome is still mainly symptomatic. | |
14564635 | Crohn's disease complicated by adult-onset Still's disease. | 2003 | A 31-year-old man with Crohn's disease developed arthritis, spiking fever, and skin rash indistinguishable from that of adult-onset Still's disease. He was admitted to our hospital because of a periumbilical intestinal skin fistula. Crohn's disease had been diagnosed in 1991, and had required intestinal resection twice, and schizophrenia had been diagnosed in 1993. He developed polyarthritis and spiking fever, accompanied by a macular skin rash on both forearms. Marked hepatosplenomegaly and bilateral pleural effusion were detected on computed tomography examination. These findings are indistinguishable from those of adult-onset Still's disease. Because his mental status had deteriorated following high-dose prednisolone on a previous admission, he was treated with an immunosuppressive agent on this occasion, with the treatment being successful. This is the first report of adult-onset Still's disease complicating Crohn's disease. In patients with Crohn's disease, polyarthritis and skin rash can easily be misdiagnosed as enteropathic arthritis with erythema nodosum associated with the Crohn's disease. Although adult-onset Still's disease may not be fatal, early diagnosis is important because it can, in rare cases, result in life-threatening complications. | |
14719216 | Comparing the self-reported referral and management preferences of pediatricians and famil | 2003 Dec | OBJECTIVE: The symptoms of juvenile rheumatoid arthritis (JRA) are often first recognized by primary care physicians. Little is known about the determinants of the initial management and referral patterns of these physicians for children with JRA. We compared the self-reported preferences and practices of pediatricians (PD) and family physicians (FP) in the diagnosis and management of children with JRA. METHODS: Surveys were mailed to a national random sample of 700 PD and 867 FP. Questions included prior experience with JRA, usual patterns in the diagnosis and management of JRA, perception of the need for guidelines for referral and management of this condition, and physician demographic information. Data analysis included univariate and bivariate analysis. RESULTS: Response rates were 69% for PD and 49% for FP. Most respondents had seen very few JRA cases in the previous 5 years. Only 1% of respondents reported that they provided all diagnosis and management for patients with JRA. Forty-two percent of PD and 32% of FP refer all JRA diagnosis and management to subspecialists, while 46% of PD and 61% of FP refer only to confirm the diagnosis and guide initial therapy (p = 0.011). More PD than FP (PD 92% vs FP 76%; p = 0.001) referred patients with JRA to pediatric rheumatologists, while more FP than PD referred to general rheumatologists (PD 17% vs FP 37%; p = 0.001). The majority of FP reported feeling more comfortable managing rheumatologic disease in adults than children (82%). Few respondents felt that they were up to date on the latest advances in JRA treatment (PD 10% vs FP 4%; p = 0.024). CONCLUSION: Multiple factors may contribute to physicians' referral practice, including a patient's clinical status and the physician's beliefs of inadequacy of training and inability to stay up to date. The pattern of care that children with JRA receive likely will be influenced by initial presentation to a PD or to a FP. | |
12563701 | Health status of patients with juvenile rheumatoid arthritis at 1 and 5 years after diagno | 2003 Feb | OBJECTIVE: To describe the health and functional status of children with juvenile rheumatoid arthritis (JRA) diagnosed in the early 1990s. METHODS: Patients were obtained from the Pediatric Rheumatology Disease Registry, a database of patients seen in pediatric rheumatology centers across the United States. Questionnaires designed to be filled out after retrospective chart review were sent to pediatric rheumatologists caring for children diagnosed with JRA between 1992 and 1997. RESULTS: We studied 703 patients -- 376 with pauciarticular onset (pauci), 232 with polyarticular onset (poly), and 95 with systemic onset JRA (systemic). At 1 year after diagnosis, half of the pauci and systemic patients no longer required medication, compared to 78% of the poly patients; 98% of the patients functioned in Steinbrocker classes I and II. Six percent of pauci, 27% of poly, and 11% of systemic patients had limitations in school function. Nearly 1/3 of poly patients already had joint space narrowing on radiograph. By 5 years after diagnosis, all pauci, 88% of poly, and 70% of systemic patients were in Steinbrocker classes I and II; but 6% of pauci, 28% of poly, and 44% of systemic patients had limitations in school function. Nearly 2/3 of poly and systemic patients had joint space narrowing. CONCLUSION: In these children treated prior to the era of biologic therapy, at 5 years after onset, > 25% of poly and nearly half of systemic patients had functional limitations that required modifications in their school schedule. Radiographically evident joint space damage was seen within a year of onset in poly patients, and by 5 years 2/3 of poly and systemic patients had damage. | |
12653236 | Morphological changes of parotid glands following adjuvant arthritis and ibuprofen treatme | 2003 Feb | Drug administration and numerous systemic diseases may cause morphological changes of the parotid gland. The aim of this study was to investigate the possible relationship between experimental adjuvant arthritis following ibuprofen treatment and morphological alterations of the parotid glands in rats. Freud's adjuvant was injected intradermally into the plantar surface of the hind paw of the animals to induce experimental arthritis. Ibuprofen was administrated per os (17 mg/kg/day). Both adrenals and parotid glands were isolated and their absolute and relative weights were evaluated. A full histological examination of parotid glands took place. The diameter of the foot as well as the serum levels of rheumatoid factor was measured. In conclusion, both experimental adjuvant arthritis and ibuprofen treatment induce morphological changes of the parotid tissues, which are related to macro- and micro-structure of the gland. | |
12920473 | Treatment of refractory juvenile idiopathic arthritis via pulse therapy using methylpredni | 2003 May 5 | CONTEXT: Patients with refractory juvenile idiopathic arthritis can benefit from aggressive therapy. CASE REPORT: We followed the clinical course of 4 patients (2 male, 2 female) aged 9.1-17.8 years (mean of 14.5 years) with polyarticular onset of juvenile rheumatoid arthritis and one 16-year-old boy with juvenile spondyloarthropathy associated with inflammatory bowel disease. All the juvenile rheumatoid arthritis patients fulfilled the diagnostic criteria established by the American College of Rheumatology. All patients had unremitting arthritis despite maximum therapy. All patients began receiving treatment using intravenous cyclophosphamide at 500-750 mg/m and intravenous methylprednisolone at 30 mg/kg, for 3 days monthly (1 g maximum). The patients received between 3 and 11 monthly treatments, and/or 3-5 treatments every two months for 12 months, according to the severity of the disease and/or response to the therapy. All but one patient were evaluated retrospectively at the start (time 0) and 6 months (time 1), and 12 months (time 2) after the beginning of the treatment. A rapid and clinically significant suppression of systemic and articular manifestations was seen in all patients. Our results showed the favorable effect of this treatment on the clinical and some laboratory manifestations of juvenile idiopathic arthritis. | |
12788115 | Surgical management of cataracts in children with juvenile rheumatoid arthritis-associated | 2003 Jun | PURPOSE: To evaluate outcomes of cataract surgery with posterior chamber intraocular lens (IOL) implantation with or without trabeculectomy in children with juvenile rheumatoid arthritis (JRA)-associated uveitis. DESIGN: Interventional case series. METHOD: Retrospective chart review of five patients aged 12 years or younger with JRA-associated uveitis who underwent cataract surgery with posterior chamber IOL with or without trabeculectomy at the Cleveland Clinic Foundation from December 1995 to October 2001. RESULTS: Four female patients and one male patient ranging from age 7 to 12 years were identified. One patient had bilateral involvement; six eyes were included in the study. Three eyes underwent cataract extraction with posterior chamber IOL, and three underwent combined cataract surgery with posterior chamber IOL and trabeculectomy. Median age at surgery was 8.5 years, with a median follow-up of 43.5 months. Four of five children (five eyes) were on systemic methotrexate immunosuppressive therapy for a median length of 1.25 years before surgery. Two of five patients (three eyes) were also on additional systemic immunosuppressive or anti-inflammatory treatments. All eyes received frequent topical corticosteroid therapy for a median of 2 weeks preoperatively and 8.5 weeks postoperatively. A final postoperative Snellen visual acuity of 20/40 or better was achieved in all children. A median final visual acuity improvement of 7 Snellen lines was observed after cataract surgery. CONCLUSIONS: With adequate long-term preoperative and postoperative control of intraocular inflammation with systemic immunosuppressive therapy in addition to intensive topical corticosteroid treatment, children with JRA-associated uveitis can demonstrate favorable surgical outcomes after cataract surgery with posterior chamber IOL. | |
12486538 | [The influence of rheumatoid and degenerative disease on hospital resources in the operati | 2002 Dec | The aim of this study was to compare perioperative diagnostic and therapeutic measures in the treatment of cervical spine instability in patients with rheumatoid arthritis or degenerative disease. Twenty patients (ten in each group) were evaluated and compared with regard to age, sex, surgery time, total operating room time, intensive care time, extent of physical therapy, nursing requirements, costs of medication and radiography. Rheumatoid arthritis patients required more resources with regard to surgery, nursing and rehabilitation than the patients with degenerative disease. Significant differences existed with regard to patient age (P=0.0005), surgery time (P=0.0021), total operating room time (P=0.0001), duration of intensive care (P=0.0005), nursing requirements (P=0.0000), costs of medication (P=0.0000), costs of radiography (P=0.0015) and the duration of hospitalisation (P=0.0115). The data suggest that it is necessary to distinguish patients with rheumatoid or degenerative cervical spine instability from an economic point of view, as the treatment of the rheumatoid cervical spine requires more resources. | |
15341088 | [Potential influence of nicotine on inflammation and induction of autoantibodies in rats w | 2004 May | The influence of chronic administration of nicotine diluted in the drinking water on the parameters of systemic inflammation and autoimmune processes in rats (August line) with adjuvant-induced arthritis, were studied. The experiments have shown that nicotine acts as an antiphlogistic means (the amount of C-reactive protein rises in the blood) and activates autoimmune processes: induction of rheumatic factor, of autoantibodies to serotonin, and glial fibrillar acid protein. It was supposed that nicotine has a potential impact on immunocompetent cells. | |
15799307 | [Serum rheumatoid factor and peripheral blood eosinophil counts in patients with bronchial | 2004 Dec | These days some reports say that bronchial asthma, especially severe asthma, is systemic inflammatory and its severity correlates with eosinophil counts. Some patients with asthma have positive tests for rheumatoid factor (RF) which is detected in systemic hyper immunoreactive desease such as rheumatoid arthritis. So we investigated each of these factors in asthmatic patients. We randomly selected 100 asthmatics from regular outpatients of our hospital. In a positive RF level group (over 21 IU/ml), Eosinophil counts were significantly higher than those in a negative RF level group. RF levels were significantly and positively correlated with the logarithm of eosinophil count. And in severe groups (patients with severe asthma, treated with high dose inhaled steroids, and with history of systemic steroids use for the last one month), RF levels were significantly higher than those in other groups. Our result suggested that RF levels reflect eosinophilia and asthma severity. | |
24383825 | Wnt signaling in rheumatoid synoviocyte activation. | 2002 Mar | Abstract Rheumatoid arthritis (RA) is a joint-specific disease with complex pathogenesis. It is characterized by synovial inflammation, cartilage loss, and joint destruction. The reasons why joint damage recurs when therapy is discontinued are not clearly understood. Several lines of evidence suggest that cartilage damage is promoted by the transformed and invasive fibroblast-like synoviocytes (FLS) of the rheumatoid joint. It has been demonstrated in several systems that aberrant wnt-mediated signaling causes blockade of cartilage differentiation and malformation of joints. In this review, we have discussed the importance of wnt-frizzled-mediated signaling in the autonomous activation of FLS in patients with RA. Anti-wnt/anti-frizzled antibodies, frizzled receptor antagonists, or small molecule inhibitors of wnt-frizzled signaling might be useful for therapeutic interventions in RA. | |
11959768 | gammadelta T cell subsets in patients with arthritis and chronic neutropenia. | 2002 May | BACKGROUND: An abnormal distribution of subsets of gammadelta T cells, which are a component of the inflammatory infiltrate in arthritic synovium, has been demonstrated in the peripheral blood (PB) of patients with arthritis and neutropenia. OBJECTIVE: To evaluate whether the clinical manifestations of patients with arthritis and neutropenia are related to the specific gammadelta T cell subset predominant in the PB. METHODS: Flow cytometry of PB lymphocytes in six consecutive patients with chronic neutropenia and arthritis was performed. Variable (V) gamma and delta gene families were analysed by polymerase chain reaction. cDNA was subjected to direct automated sequencing of T cell receptor (TCR) genes. RESULTS: Three patients had non-deforming and non-erosive rheumatoid factor (RF)(+) polyarticular rheumatoid arthritis, RF(+) oligoarticular arthritis, or RF(-) non-deforming oligoarticular psoriatic arthritis with persistent expansions of Vgamma1(+)/Vdelta2(+), Vgamma2(+)/Vdelta2(+), or Vgamma1(+)/Vdelta (undetermined (2- 1-)) T cells, respectively. The other three patients, without persistent expansion of gammadelta T cells, had either non-deforming and non-erosive oligo- or polyarthritis with a balanced distribution of several Vdelta and Vgamma genes, or severe erosive RF(+) arthritis with deficiency of all but Vgamma1(+)/Vdelta1(+) T cells. CONCLUSIONS: gammadelta T cell lymphoproliferations in chronic neutropenia and arthritis use different Vgamma and Vdelta gene families, often forming T cell receptor (TCR) structures that are infrequent in normal adult PB. Arthritis with Vgamma1(+)/Vdelta2(+), Vgamma2(+)/Vdelta2(+), or Vgamma1(+)/Vdelta2(-)/Vdelta1(-) gammadelta T cells in the PB is non-deforming and non-erosive, suggesting a protective effect of these cells, as opposed to a more pathogenic contribution of Vgamma1(+)/Vdelta1(+) cells. | |
11860612 | Norepinephrine-evoked pain in fibromyalgia. A randomized pilot study [ISRCTN70707830]. | 2002 | BACKGROUND: Fibromyalgia syndrome displays sympathetically maintained pain features such as frequent post-traumatic onset and stimuli-independent pain accompanied by allodynia and paresthesias. Heart rate variability studies showed that fibromyalgia patients have changes consistent with ongoing sympathetic hyperactivity. Norepinephrine-evoked pain test is used to assess sympathetically maintained pain syndromes. Our objective was to define if fibromyalgia patients have norepinephrine-evoked pain. METHODS: Prospective double blind controlled study. PARTICIPANTS: Twenty FM patients, and two age/sex matched control groups; 20 rheumatoid arthritis patients and 20 healthy controls. Ten micrograms of norepinephrine diluted in 0.1 ml of saline solution were injected in a forearm. The contrasting substance, 0.1 ml of saline solution alone, was injected in the opposite forearm. Maximum local pain elicited during the 5 minutes post-injection was graded on a visual analog scale (VAS). Norepinephrine-evoked pain was diagnosed when norepinephrine injection induced greater pain than placebo injection. Intensity of norepinephrine-evoked pain was calculated as the difference between norepinephrine minus placebo-induced VAS scores. RESULTS: Norepinephrine-evoked pain was seen in 80 % of FM patients (95% confidence intervals 56.3 - 94.3%), in 30 % of rheumatoid arthritis patients and in 30 % of healthy controls (95% confidence intervals 11.9 - 54.3) (p < 0.05). Intensity of norepinephrine-evoked pain was greater in FM patients (mean +/- SD 2.5 +/- 2.5) when compared to rheumatoid arthritis patients (0.3 +/- 0.7), and healthy controls (0.3 +/- 0.8) p < 0.0001. CONCLUSIONS: Fibromyalgia patients have norepinephrine-evoked pain. This finding supports the hypothesis that fibromyalgia may be a sympathetically maintained pain syndrome. | |
15167194 | Necrotizing fasciitis of the leg presenting with chest wall emphysema. | 2004 Feb | We present the case of a 70-year-old woman with necrotizing fasciitis of the right leg, sepsis and bacteraemia with Escherichia coli. Chest wall emphysema, detected on standard radiograph and the presence of air in the soft-tissue of the foot was the reason for prompt surgical drainage in addition to standard fluid resuscitation and antibiotic therapy. There was no evidence of underlying diabetes mellitus, but unknown chronic renal failure and corticosteroid therapy for rheumatoid arthritis were considered predisposing factors. We present a short overview of this rare life-threatening condition with emphasis on radiological diagnostic modalities. | |
12378831 | [Multicentric reticulohistiocytosis with a 20-year follow-up ]. | 2002 Sep | INTRODUCTION: Multicentric reticulo-histiocytosis also known as lipoid dermoarthritis is a rare systemic disease leading to a massive osteoarticular destruction and systemic complications. EXEGESIS: This case report is a 44 year old black woman who was first seen with a rheumatoid arthritis clinical presentation associated with the presence of rheumatoïd factor. Five years later the diagnosis has been reconsidered after skin nodules histological examination. After that the patient has been lost from the follow up clinic. After a twenty years evolution she presented a complex clinical picture including: a cutaneous syndrome with a non pruriginous and hyperchromic papulonodular rash on the arms and fore-arms; a very destructive polyarthritis with major handicap; and systemic manifestations like cardiomyopathy with heart failure. The heart failure treatment associated first corticosteroids and secondary chloroquine was successful. CONCLUSION: The rheumatoid factor presence should not avoid to consider the possibility of multicentric reticulohistiocytosis in case of polyarthritis associated with a papulonodular rash. Then skin biopsy must be performed. The severity of osteoarticular and systemic lesions require an early prescription of a treatment for which there is so far no compromise. | |
12920692 | Potential of tumor necrosis factor neutralization strategies in rheumatologic disorders ot | 2003 Aug | OBJECTIVES: To consider the potential of tumor necrosis factor (TNF) neutralization in rheumatologic disorders other than rheumatoid arthritis (RA). METHODS: Literature on the safety and efficacy of TNF inhibition in the treatment of non-RA arthropathies and systemic inflammatory diseases from American and European medical journals was reviewed. RESULTS: Clinical trials, open-label studies, and case studies indicate great promise for TNF inhibitors alone or in combination with other protocols in the treatment of non-RA rheumatologic disorders. In randomized, double-blind, placebo-controlled trials of etanercept and open-label studies of infliximab in patients with psoriatic arthritis, these 2 TNF inhibitors resulted in an approximately 80% to 90% response rate. Double-blind, placebo-controlled, randomized trials also indicate an encouraging degree of efficacy in patients with ankylosing spondylitis. Preliminary evidence from open-label trials and case studies suggests that these TNF inhibitors also may be effective in the treatment of Behçet disease, Wegener granulomatosis, and sarcoidosis. CONCLUSIONS: Neutralization of TNF may have an important role in the treatment of rheumatologic disorders other than RA. | |
12124855 | An epidemiologic study of trends in prevalence of rheumatoid factor seropositivity in Pima | 2002 Jul | OBJECTIVE: Previous population studies have suggested that both rheumatoid factor (RF) production and rheumatoid arthritis (RA) may be declining in occurrence, and both secular and birth-cohort influences have been implicated. Since Pima Indians have a very high incidence of RA and also have shown recent evidence of a decline in RA, this study evaluated the relative contributions of age, secular, and birth-cohort influences on RF seropositivity in the Pima Indian population. METHODS: RF data, as assayed by both the bentonite flocculation test (BFT) and the sheep cell agglutination test (SCAT), were available on 5,345 Pima Indians born between 1886 and 1975, who were surveyed at biennial intervals between 1966 and 1995. An age-period-cohort analysis was conducted using data on 18,295 examinations undertaken during the period of study. RESULTS: There was a decline in the proportion of positive test results for RF (titer > or = 1:32) by both BFT and SCAT, in both male and female subjects from 1966-1975 to the later decades of the study (1976-1985 and 1986-1995). Across all periods, by both assays, the crude proportion of positive titers increased with increasing age of the subjects. There was a very clear birth-cohort effect: the highest likelihood of seropositivity was in those individuals born around the end of the nineteenth century, with continuing decline in seropositivity up to the most recent birth cohort. A logistic regression analysis, adjusting for Pima heritage and sex, demonstrated a substantially greater influence of birth cohort than of calendar year on the frequency of RF positivity. CONCLUSION: In the Pima Indian population, environmental influences in early life are important predictors of the lifelong likelihood of RF positivity. This may have implications for understanding the epidemiology and etiology of RA. |
