16356192 | Adalimumab clinical efficacy is associated with rheumatoid factor and anti-cyclic citrulli | 2006 | Studies on autoantibody production in patients treated with tumor necrosis factor-alpha (TNF-alpha) inhibitors reported contradictory results. We investigated in a prospective study the efficacy of a treatment with human monoclonal anti-TNF-alpha antibody (adalimumab) in patients with rheumatoid arthritis (RA) and we evaluated the relationship between treatment efficacy and the incidence and titers of disease-associated and non-organ-specific autoantibodies. Fifty-seven patients with RA not responsive to methotrexate and treated with adalimumab were enrolled. Antinuclear, anti-double-stranded(ds)DNA, anti-extractable nuclear antigens, anti-cardiolipin (aCL), anti-beta2 glycoprotein I (anti-beta2GPI) autoantibodies, rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) autoantibodies were investigated at baseline and after 6 and 12 months of follow-up. Comparable parameters were evaluated in a further 55 patients treated with methotrexate only. Treatment with adalimumab induced a significant decrease in RF and anti-CCP serum levels, and the decrease in antibody titers correlated with the clinical response to the therapy. A significant induction of antinuclear autoantibodies (ANA) and IgG/IgM anti-dsDNA autoantibodies were also found in 28% and 14.6% patients, respectively, whereas aCL and anti-beta2GPI autoantibodies were not detected in significant quantities. No association between ANA, anti-dsDNA, aCL and anti-beta2GPI autoantibodies and clinical manifestations was found. Clinical efficacy of adalimumab is associated with the decrease in RF and anti-CCP serum levels that was detected after 24 weeks and remained stable until the 48th week of treatment. Antinuclear and anti-dsDNA autoantibodies, but not anti-phospholipid autoantibodies, can be induced by adalimumab but to a lower extent than in studies with other anti-TNF blocking agents. | |
15864685 | Immune thrombocytopenic purpura associated with rheumatoid arthritis: case report. | 2005 Nov | A 54-year-old Japanese woman was diagnosed with rheumatoid arthritis (RA) in 1995 on the basis of symmetric effusive polyarthritis, morning stiffness, and strongly positive rheumatoid factor. She had received low-dose prednisolone, indomethacin, methotrexate (MTX), and cyclophosphamide (CPA), at least, over 4 years before the current admission and showed partial improvement of polyarthralgia. In November 2002, she suddenly developed thrombocytopenia (platelet count was 0.3 x 10(4) mm(-3)) with purpura and was diagnosed with immune thrombocytopenic purpura (ITP). As she had refractory ITP, the administration of pulsed high-dose dexamethasone (DEX) therapy was started, resulting in the complete remission of ITP. The present paper reports that pulsed high-dose DEX therapy was useful for the treatment of refractory ITP associated with RA. | |
16450150 | [T-large granular lymphocyte leukaemia. An important differential diagnosis to Felty's syn | 2006 Sep | T-Large Granular Lymphocyte (T-LGL) leukaemia is a rare clonal disease characterized by neutropenia and/or anaemia. Because of its strong association with rheumatoid arthritis (RA), T-LGL leukaemia is an important differential diagnosis to Felty's syndrome. This differentiation might be especially difficult since, in severe RA with extraarticular manifestations, there is often an expanded memory effector T-cell population which can hardly be separated from T-LGL leukaemia cells by means of immunophenotyping. The main criterion for T-LGL leukaemia is the detection of a clonal T-cell-receptor rearrangement by PCR. First-line therapy consists of weekly low-dose methotrexate. Alternatively, other immunosuppressives or cytotoxic agents can be useful. There are very limited data from therapy studies. The German CLL study group has initiated a protocol using parenteral low-dose methotrexate as first-line therapy and fludarabine as second-line medication. | |
16414968 | Do patients with older-onset rheumatoid arthritis receive less aggressive treatment? | 2006 Sep | Rheumatoid arthritis among elderly people is an increasingly important health concern. Despite several cross-sectional studies, it has not been clearly established whether there are important clinical differences between elderly-onset rheumatoid arthritis (EORA) and younger-onset rheumatoid arthritis (YORA). The aim of this study was to compare disease activity and treatment in EORA and YORA, using the Consortium of Rheumatology Researchers of North America (CORRONA) registry, a database generated by rheumatologist investigators across the USA. From the CORRONA registry database of 9381 patients with rheumatoid arthritis, 2101 patients with disease onset after the age of 60 years (EORA) were matched, on the basis of disease duration, with 2101 patients with disease onset between the ages of 40 and 60 years (YORA). The primary outcome measures were the proportion of patients on methotrexate, multiple disease-modifying antirheumatic drugs (DMARD) and biological agents (etanercept, infliximab, adalimumab and kineret) in each group. Disease activity and severity differed slightly between the EORA and YORA groups: Disability Index of the Health Assessment Questionnaire: 0.30 v 0.35; tender joint count: 3.7 v 4.7; swollen joint count: 5.3 v 5.2; Disease Activity Score 28: 3.8 v 3.6; patient global assessment: 29.1 v 30.9; physician global assessment: 24.9 v 26.3; patient pain assessment: 31.4 v 34.9. Regarding treatment, the use of methotrexate use was slightly more common among patients with EORA (63.9%) than among those with YORA (59.6%), although the mean methotrexate dose among the YORA group was higher than that in the EORA group. The percentage of patients with EORA who were on multiple DMARD treatment (30.9%) or on biological agents (25%) was considerably lower than that of patients with YORA (40.5% and 33.1%, respectively; p<0.0001). Toxicity related to treatment was very minimal in both groups, whereas toxicities related to methotrexate were more common in the YORA group. Patients with EORA receive biological treatment and combination DMARD treatment less frequently than those with YORA, despite identical disease duration and comparable disease severity and activity. | |
15853437 | Modelling cost effectiveness and cost utility of sequential DMARD therapy including leflun | 2005 | OBJECTIVE: To quantify direct costs of medication and cost of illness (according to functional capacity) for patients with rheumatoid arthritis (RA) in Germany, allowing further use in a health economic evaluation of sequential therapy with disease-modifying antirheumatic drugs (DMARDs) in specialised, i.e. rheumatological, care in Germany. DESIGN AND SETTING: The analysis was conducted from the societal perspective in Germany using a modelling approach, which was based on secondary analysis of existing data and on data from a sample of 583 patients from the German rheumatological database of 1998. Functional capacity was defined by the Hannover Functional Ability Questionnaire (HFAQ) scores. Costs were calculated from resources utilised and patients' work capacity. Direct costs consisted of outpatient medical services, inpatient treatment, long-term care and rehabilitation treatment. Indirect costs incurred by sick leave and premature retirement were quantified according to the human-capital approach. MAIN OUTCOME MEASURES AND RESULTS: Average total direct costs (year 1998-2001 values) per patient per year for continuous treatment with the selected DMARDs comprising costs for drugs, monitoring and treatment of adverse drug reactions (ADRs) were highest for intramuscular gold (sodium aurothiomalate) [euro 2106 (euro 1 approximately equal to $US 0.91; average of the period from 2000 through 2001)] followed by leflunomide (euro 2010), azathioprine (euro 1878), sulfasalazine (euro 1190), oral methotrexate (euro 708), and lowest for the antimalarials chloroquine/hydroxychloroquine (euro 684). There were additional yearly costs for RA-related non-DMARD medication of euro 554 per patient, including management of ADRs. Mean cost of illness (year 1998 values) excluding medication cost amounted to euro 17,868 per RA patient per year. Annual costs increased with increasing disability, i.e. decreasing functional capacity, of RA patients from euro 6029 per patient with more than 94% of functional capacity to euro 28,509 per patient with <20% of functional capacity. In general, there was a predominance of indirect costs in each of the categories of functional capacity, ranging between 74% and 87% of total (direct and indirect) annual costs per RA patient. Annual direct costs increased from euro 811 to euro 7438 per patient with increasing disability. Inpatient treatment was the predominant component of direct costs. Patients in the worst category (<20%) of function experienced hospital costs that were 6.5 times higher than those of patients in the best category (>94%). CONCLUSIONS: On the basis of the data presented it can be concluded that the results of this investigation are typical for patients in rheumatological care in Germany and can therefore be used in a health economic analysis of different DMARD sequences aimed at changing disease progression over time. | |
17141365 | Methotrexate-associated lymphoproliferative disorder in a patient with rheumatoid arthriti | 2007 Apr | A 91-year-old woman who had been taking methotrexate for approximately 5 years for rheumatoid arthritis developed papules and nodules on her face that enlarged during 6 months. A series of biopsy specimens demonstrated a lymphoplasmacytic infiltrate with increasingly atypical histopathologic features that resembled diffuse large B-cell lymphoma. Epstein-Barr virus was not identified. Withdrawal of methotrexate resulted in complete resolution of all lesions within 8 weeks. This case illustrates the rare occurrence of methotrexate-associated lymphoproliferative disorder with primary presentation in the skin and documents clinical and histopathologic progression from early changes to fully developed lesions. | |
16948115 | IgG and IgM anticardiolipin antibodies following treatment with infliximab plus methotrexa | 2006 Sep | OBJECTIVE: To assess the occurrence of anticardiolipin antibodies (aCL) in patients with early rheumatoid arthritis (RA) receiving treatment with infliximab plus methotrexate (MTX) versus MTX alone. METHODS: The first 299 patients enrolled in the randomized, Active-Controlled Study of Patients Receiving Infliximab for the Treatment of Rheumatoid Arthritis of Early Onset (ASPIRE) trial who had baseline (week 0) samples available for aCL testing were included in this study. Sera were collected at weeks 0, 30, and 54 from 110 patients taking infliximab 3 mg/kg plus MTX, 98 patients taking infliximab 6 mg/kg plus MTX, and 91 patients taking placebo plus MTX. IgG and IgM aCL were measured using an anticardiolipin assay. RESULTS: IgG and IgM aCL positivity at baseline was similar in all treatment groups. Most patients were negative for IgG aCL at baseline and remained so at the last followup evaluation. One percent (2 of 208) of patients who received infliximab plus MTX and were negative for IgG aCL at baseline were positive for IgG aCL at weeks 30 and 54. A slightly higher proportion of patients who received infliximab plus MTX and were negative for IgM aCL at baseline were positive for IgM aCL at weeks 30 and 54 (4.8% [10 of 208]) as compared with patients who received placebo plus MTX (1.1% [1 of 91]), but the difference was not significant. CONCLUSION: There was a low incidence of the development of aCL in patients with early RA who received infliximab in combination with MTX, and the difference was not significant compared with patients who received placebo plus MTX. | |
16508932 | Infliximab treatment maintains employability in patients with early rheumatoid arthritis. | 2006 Mar | OBJECTIVE: To evaluate the impact of infliximab therapy on the employment status of patients with early rheumatoid arthritis (RA). METHODS: Methotrexate (MTX)-naive patients with active early RA were randomly allocated to receive MTX plus placebo or MTX plus infliximab (3 mg/kg or 6 mg/kg) at weeks 0, 2, and 6 and then every 8 weeks through week 46. Data for patients younger than age 65 years were included in the analyses. A patient was categorized as employable if he or she was employed or felt well enough to work if a job were available. RESULTS: The change in actual employment was not significantly different between patients receiving MTX plus infliximab and those receiving MTX plus placebo (0.5% versus 1.3%; P > 0.5). However, the proportion of patients whose status changed from employable at baseline to unemployable at week 54 was smaller in the group receiving MTX plus infliximab compared with that in the group receiving MTX alone (8% versus 14%; P = 0.05). Patients who were treated with infliximab plus MTX had a significantly greater likelihood of improvement rather than deterioration in employability (odds ratio 2.4; P < 0.001); this likelihood was not significantly greater in patients receiving MTX alone. The proportion of employed patients who lost workdays during the trial was smaller in the MTX plus infliximab group than in the MTX-alone group (P = 0.010). CONCLUSION: The actual employment rates among patients in the 2 treatment groups were not different. However, patients with early RA who were treated with MTX plus infliximab had a higher probability of maintaining their employability compared with those who were treated with MTX alone. | |
15166003 | Rheumatoid factor, but not anti-cyclic citrullinated peptide antibodies, is modulated by i | 2005 Feb | OBJECTIVES: To analyse the effect of infliximab on IgM rheumatoid factor (RF) and anti-cyclic citrullinated peptide (CCP) antibodies, and determine whether baseline autoantibody titres (IgM RF and anti-CCP antibodies) are associated with changes in acute phase reactants. PATIENTS AND METHODS: 62 patients with refractory RA were treated with infliximab combined with methotrexate. At baseline and week 30, serum samples were tested for IgM RF by two agglutination assays, and for anti-CCP antibodies by an ELISA. Percentage change in C reactive protein (CRP) and erythrocyte sedimentation rate (ESR) was calculated. RESULTS: At baseline and week 30 RF titres were reduced significantly during infliximab treatment (p<0.001 and p = 0.038, respectively), whereas anti-CCP antibodies were unchanged (p = 0.240). Baseline IgM RF titres, but not anti-CCP antibodies, correlated inversely with changes in CRP and ESR during treatment. Patients with a marked decrease in acute phase reactants had lower IgM RF titres than those with a smaller decrease in CRP and ESR; no significant differences were found for anti-CCP antibodies. CONCLUSION: The differential effect of infliximab treatment on IgM RF and anti-CCP antibodies, and the different predictive value on changes in acute phase reactants during infliximab treatment support the existing evidence that RF and anti-CCP antibodies are independent autoantibody systems in RA. | |
15608313 | Intermittent rises in plasma homocysteine in patients with rheumatoid arthritis treated wi | 2005 Jan | OBJECTIVES: To investigate the effect of higher weekly maintenance dose methotrexate (MTX) (> or =25 mg/week) on plasma homocysteine concentrations in adults with RA. METHODS: Patients with RA were treated with high doses of MTX with adjuvant folic acid. Plasma homocysteine was determined at baseline and 1, 2, 4, 8, 12, and 48 hours after subcutaneous MTX administration. Maximum homocysteine concentrations after MTX administration were compared with baseline concentrations. RESULTS: Fifteen patients with RA (11 women) were included, with a median age of 61 years (range 31-72) and median disease duration 7 years (range 2-32). Median MTX dose was 30 mg (range 25-40). All patients received folic acid supplementation (5-30 mg/week). Median plasma homocysteine concentration at baseline was 10.1 mumol/l (range 6.6-12.7; normal 6-15). Homocysteine concentrations increased after MTX administration by a median of 2.5 mumol/l (range 0.7-5.1). Median maximum plasma homocysteine was significantly higher than at baseline. Peak homocysteine was reached after 12 hours. No relation between serum folate concentrations and plasma homocysteine concentrations was found. CONCLUSIONS: In patients with RA higher MTX doses with adjuvant folic acid do not increase baseline concentrations of homocysteine. An intermittent significant rise in plasma homocysteine occurs in the 48 hours after MTX administration. | |
17181921 | Regulation of serum chemokines following infliximab therapy in patients with rheumatoid ar | 2006 Sep | OBJECTIVE: We studied the effects of the multiple infusions of infliximab, a chimeric anti-tumor necrosis factor alpha (anti-TNF-alpha) antibody, on the serum chemokines levels in patients with active rheumatoid arthritis (RA). METHODS: RA patients were supposed to receive 9 infusions of infliximab (3mg/kg) at weeks 0, 2, 6, and every 8 weeks thereafter with the same dose. All patients continued treatment with methotrexate (MTX) (7.5-20mg/week). Serum concentrations of interleukin-8 (IL-8), RANTES (regulated upon activation, normal T cell expressed and secreted) and monocyte chemoattractant protein-1 (MCP-1) were assessed by ELISA at weeks 0, 2, 6, 14, 38, prior to infusion, and additionally at week 62. RESULTS: Initial infusion of infliximab caused reduction in serum IL-8, RANTES and MCP-1 (in all cases p < 0.001) levels. Subsequent infliximab administrations also significantly decreased serum chemokines levels, but was less effective. Prior to the first infliximab infusion serum concentrations of studied chemokines correlated with markers of RA activity such as the erythrocyte sedimentation rate (ESR) or CRP levels, number of swollen joints and disease activity score (DAS). Following next drug infusions such associations were far less significant. Infliximab treatment induced a significant reduction in the number of monocytes observed through the whole study (in all cases p < 0.05). CONCLUSION: Anti-TNF-alpha antibody therapy accompanied by MTX, beside a rapid clinical improvement, reduced serum chemokines concentrations in RA patients. Subsequent administrations of infliximab sustained chemokines decrease, although to a lesser extent than the first two dose of infliximab. | |
17003175 | Rates and predictors of herpes zoster in patients with rheumatoid arthritis and non-inflam | 2006 Nov | OBJECTIVES: Herpes zoster (HZ) is a common disorder that causes substantial pain and morbidity. We examined its rate and predictors in rheumatoid arthritis (RA) and non-inflammatory musculoskeletal (MSK) disorders to determine if HZ was increased in RA and whether treatment contributed to the risk of HZ. METHODS: After excluding patients witzh prior HZ, we assessed 10 614 RA and 1721 MSK patients by semi-annual questionnaires during 33 825 patient-years of follow-up. Predictors of HZ were determined by Cox regression and expressed as hazard ratios (HR) and 95% confidence intervals (CI). RESULTS: The annualized incidence rate per 1000 patient-years was 13.2 (95% CI 11.9-14.5) in RA and 14.6 (95% CI 11.2-18.1) in MSK, and did not differ significantly after adjustment for age and sex. HZ was predicted by impaired functional status, as measured by the Health Assessment Questionnaire (HAQ), [HR 1.3 (95% CI 1.1-1.5)] and by the use of COX-2-specific non-steroidal anti-inflammatory drugs (NSAIDs) [HR 1.3 (95% CI 1.1-1.6)] in RA and MSK. In multivariable analyses in patients with RA, cyclophosphamide HR 4.2 (95% CI 1.6-11.5), azathioprine HR 2.0 (1.2-3.3), prednisone HR 1.5 (1.2-1.8), leflunomide HR 1.4 (1.1-1.8) and COX-2 NSAIDs HR 1.3 (95% CI 1.1-1.6) were significant predictors of HZ. CONCLUSION: The incidence of HZ is increased in RA and MSK compared with population-based rates. However, the rate of HZ in RA is not increased compared with MSK. After adjustment for severity, various treatments, but not methotrexate or biologics, were risk factors for HZ. | |
17207378 | Association of tumour necrosis factor a, b and c microsatellite polymorphisms with clinica | 2006 Nov | OBJECTIVE: To study the associations of tumor necrosis factor (TNF) a, b and c microsatellite markers with 1) the clinical disease activity and 2) the induction of remissions in patients with early rheumatoid arthritis (RA) treated with two treatment strategies. METHODS: In the FIN-RACo (FINnish Rheumatoid Arthritis Combination therapy) trial of two years, 195 patients with recent-onset RA were randomly assigned to receive either a combination (COMBI) (sulphasalazine, methotrexate, hydroxychloroquine, and prednisolone) or a single (SINGLE) (initially sulphasalazine with or without prednisolone) disease modifying antirheumatic drug (DMARD) therapy. TNF a, b and c microsatellite and HLA-DRB1 typings were carried out in 165 (79 COMBI; 86 SINGLE) study completers. RESULTS: At baseline the 28 joint disease activity scores (DAS28) of the patients positive for TNFa2, a13 or b1 microsatellite markers were significantly higher than in the other patients. In the SINGLE patients the DAS28 improved comparably in patients with (n = 31) or without (n = 53) the TNFb1 marker (NS), while the DAS28 of the TNFb1-positive COMBI patients (n = 22) improved significantly more than that of the TNFb1-negative cases (n = 57) (p = 0.014). Respective 31.8% (7/22) and 28.1% (16/57) of the COMBI patients with or without TNFb1 allele achieved remission at one year. The corresponding figure in SINGLE patients were 0% (0/31) and 20.8% (11/53) (p = 0.006). At two years the remission frequencies in the TNFb1+/TNFb1- patients in the COMBI and SINGLE were 50.0%/38.6% and 9.7%/22.6%, respectively. CONCLUSION: Early TNFb1+ RA patients have more active disease but respond more favourably to COMBI treatment than the patients without this microsatellite allele. The finding may be of clinical relevance for the choice of DMARDs in early RA. | |
17006638 | Galactosylation of IgG from rheumatoid arthritis (RA) patients--changes during therapy. | 2006 Nov | It is well documented that serum IgG from rheumatoid arthritis (RA) patients exhibits decreased galactosylation of its conservative N-glycans (Asn-297) in CH2 domains of the heavy chains; it has been shown that this agalactosylation is proportional to disease severity. In the present investigation we analyzed galactosylation of IgG derived from the patients using a modified ELISA-plate test, biosensor BIAcore and total sugar analysis (GC-MS). For ELISA and BIAcore the binding of IgG preparations, purified from the patients' sera, to two lectins: Ricinus communis (RCA-I) and Griffonia simplicifolia (GSL-II) was applied. Based on ELISA-plate test an agalactosylation factor (AF, a relative ratio of GSL-II/RCA-I binding) was calculated, which was proportional to actual disease severity. Repeated testing of several patients before and after treatment with methotrexate (MTX) alone or in combination with Remicade (a chimeric antibody anti-TNF-alpha) supplied results indicating an increase of IgG galactosylation during the treatment. This introductory observation suggests that IgG galactosylation may be an additional indicator of the RA patients' improvement. | |
17096694 | Investigation of the clinical effect of large volume leukocytapheresis on methotrexate-res | 2006 Oct | Leukocytapheresis (LCAP) is already being used in a clinical setting for the treatment of autoimmune diseases such as inflammatory bowel disease and rheumatoid arthritis, and it has been reported to be effective. However, it is totally or partially ineffective in some patients, which has forced clinicians to rethink therapeutic strategies and concurrent treatment. With the aim of enhancing the therapeutic effect, we carried out large volume leukocytapheresis, with a throughput of 5000 mL instead of the 3000-mL throughput of conventional leukocytapheresis in nine patients with rheumatoid arthritis resistant to methotrexate treatment. Using Cellsorba, the column filled with the unwoven fabric made of the polyethylene phthalate, a leukocyte removal filter, large volume leukocytapheresis was carried out once a week for a total of five sessions. The observation period was the 12-week period following completion of treatment. The American College of Rheumatology (ACR) core set was used for assessment of efficacy. Eight weeks after completion of treatment, a 20% improvement in ACR was observed in 77.8% (7/9) of subjects, a 50% improvement in ACR was seen in 55.6% (5/9) of subjects, and a 70% improvement in ACR was observed in 22.2% (2/9) of subjects. C-reactive protein decreased gradually as treatment progressed, and a significant decrease was observed 4 weeks after completion of treatment. The fact that some subjects had an ACR70 response, few reports of which are observed in the case of conventional leukocytapheresis, and the fact that the effect continued up to 12 weeks after completion of treatment suggests that the degree and duration of the effect of large volume leukocytapheresis might be longer than those of conventional leukocytapheresis. | |
17213520 | Correlation between methotrexate efficacy & toxicity with C677T polymorphism of the methyl | 2006 Nov | BACKGROUND & OBJECTIVES: C677T polymorphism in the methylenetetrahydrofolate reductase (MTHFR) gene has been proposed as a pharmacogenomic marker for toxicity of methotrexate (MTX). We studied the relationship between the C677T gene polymorphism and toxicity and efficacy of MTX in patients with rheumatoid arthritis (RA) on folate supplementation. METHODS: A total of 150 RA patients fulfilling American College of Rheumatology (ACR) criteria and on MTX treatment were evaluated. The mean age of the patients was 42.9 +/- 11.1 yr, mean disease duration was 7.65 +/- 5.2 yr and the mean duration of MTX treatment was 26.1 +/- 20.6 months. Genotype analysis of MTHFR gene was done by PCR and restriction enzyme method. Primary endpoint for treatment efficacy was change in disease activity score 28 (DAS28) from baseline. Drug toxicity was evaluated by blood count, renal and liver function tests and a standardized questionnaire. RESULTS: The mean DAS at baseline was 5.02 +/- 0.8. All patients received 10 mg/wk folic acid supplementation. Forty two per cent (63/150) of the patients had C677T polymorphism of which 4 were homozygous (T/T) and 59 were heterozygous (C/T). The baseline characteristics of the patients with or without polymorphism were comparable. The frequency of adverse events was not increased in patients with C677T polymorphism with 11 patients experiencing adverse events as compared to 19 in the group without polymorphism (of whom 4 and 7 patients respectively discontinued treatment). The C677T polymorphism was not associated with any difference in response to treatment. INTERPRETATION & CONCLUSION: Our findings suggest that C677T polymorphism in the MTHFR gene is not predictive of toxicity or efficacy of MTX treatment in RA patients receiving folate supplementation. Further studies need to be done to look at polymorphisms in other enzymes that may have association with MTX clinical efficacy and toxicity. | |
16385521 | Ultrasonographic and radiographic results from a two-year controlled trial of immediate or | 2006 Jan | OBJECTIVE: To compare the impact of immediate and delayed introduction of anti-tumor necrosis factor therapy on inflammation and structural damage in methotrexate (MTX)-treated patients with early rheumatoid arthritis (RA). METHODS: Twenty-four patients with erosive early RA (duration < 3 years) who were receiving MTX were randomized to receive infliximab 5 mg/kg or placebo infusions at weeks 0, 2, and 6, and then every 8 weeks through week 46. Beginning at week 54 and thereafter, all patients received infliximab 5 mg/kg. Metacarpophalangeal joints were scanned using high-frequency ultrasonography and power Doppler imaging. Radiographs were evaluated using the modified Sharp/van der Heijde scoring system. RESULTS: From baseline to week 54, total synovial thickness was significantly improved in the infliximab + MTX group compared with the placebo + MTX group (median reduction 95.8% versus 37.5%; P = 0.005), as was the total color Doppler area (CDA; vascularity assessment) (median reduction 100% and 47.1%, respectively; P = 0.025). From week 0 to week 110, no significant between-group difference was observed in the change from baseline for total synovial thickening or the total CDA. At week 54, greater progression in the Sharp/van der Heijde score was apparent in patients receiving placebo + MTX compared with those receiving infliximab + MTX. Although radiographic progression in the placebo + MTX group was greatly reduced in the second year (after initiation of infliximab therapy), marked differences were observed between the infliximab + MTX group (median change in the Sharp/van der Heijde score 4.0) and the placebo + MTX group (median change 14.5) from baseline to week 110 (P = 0.076). CONCLUSION: The results indicate that the efficacy of 2 years of combination therapy with infliximab + MTX for inhibiting cumulative structural damage was superior to that of 1 year of treatment with MTX alone followed by the addition of infliximab. | |
15948014 | Intra-articular methotrexate in the treatment of rheumatoid arthritis and psoriatic arthri | 2006 Mar | The aim of our study was to evaluate the effects of intra-articular methotrexate (MTX) in patients with rheumatoid arthritis (RA) and psoriatic arthritis (PsA). Twenty-three consecutive patients, 10 with RA and 13 with PsA, with prevalent or unique arthritic involvement of one knee, were treated with intra-articular injections of MTX 10 mg every 7 days for 8 weeks. Before the beginning of the treatment and after 9 and 17 weeks, the patients underwent a clinical evaluation measuring maximal knee flexion angle, visual analog scale (VAS) and erythrocyte sedimentation rate (ESR). On the same days, an ultrasonographic examination of the involved knee was performed by two independent experienced operators. Synovial thickness in the suprapatellar bursa and the presence of joint effusion and Baker's cyst were assessed. An increase of the mean value of maximal knee flexion angle and a reduction of the mean values of ESR and VAS between T0, T9 and T17 were demonstrated. Ultrasonographic evaluation showed significant reduction of synovial thickness and joint effusion. No differences were detected for the presence of Baker's cyst. We may conclude that repeated intra-articular injections of MTX resulted in a decrease of local as well as systemic inflammatory signs. As far as we know, this is the first study that explores the effects of intra-articular MTX in RA and PsA both clinically and by ultrasonography. | |
16652437 | Adalimumab for treating rheumatoid arthritis. | 2006 Jun | OBJECTIVE: To assess the efficacy and safety of adalimumab in the treatment of rheumatoid arthritis (RA). METHODS: A Cochrane systematic review was performed. The literature search, selection and assessment of the methodological quality of the studies, and the data extraction were performed according to the standard methodology of the Cochrane reviews. Outcome measures included American College of Rheumatology (ACR) and European League Against Rheumatism responses, Disease Activity Score 28 and components of the ACR response, and radiographic and safety data. Weighted mean difference and relative risk were used for reporting continuous and dichotomous data, respectively. Number needed to treat (NNT) or to harm (NNH) were estimated when appropriate. When significant heterogeneity was not found, data were pooled. RESULTS: Six studies with 2,390 patients were included in this review. With adalimumab 40 mg every other week (eow) + methotrexate versus placebo + methotrexate, the absolute risk differences to achieve an ACR20, ACR50, and ACR70 response at 52 weeks were 35%, 32%, and 19% with NNT of 2.9, 3.1, and 5.3, respectively. At 52 weeks, adalimumab 40 mg eow and 20 mg every week (ew) significantly slowed the radiological progression. With adalimumab 40 mg eow versus placebo, the absolute risk differences to achieve an ACR20, ACR50, and ACR70 response at 24/26 weeks were 23.64%, 15.31%, and 12.22% with NNT of 5.0, 7.0, and 9.0, respectively. In most of the analyzed studies and comparisons, there were no significant differences in safety outcomes between adalimumab and control groups. CONCLUSION: On the basis of studies reviewed here, adalimumab is efficacious in the treatment of RA. No serious adverse effects occurred. | |
17137624 | Simultaneous diagnosis of CD3+ T-cell large granular lymphocyte leukaemia and true thymic | 2007 Jul | CD3+ T-cell large granular lymphocyte (LGL) leukaemia is a mature T-cell neoplasm of cytotoxic T-lymphocytes. Neutropenia represents the most frequent peripheral blood cytopenia associated with CD3+ T-cell LGL leukaemia. A wide variety of diseases associated with LGL leukaemia have been reported, both autoimmune and neoplastic. We describe for the first time the association of true thymic hyperplasia with CD3+ T-cell line LGL leukaemia. The patient presented with severe symptomatic neutropenia. Complete and persistent haematological and molecular remission was induced with an association of low-dose methotrexate and cyclosporin A, followed by thymectomy. |
