16322085 Trends in disease modifying antirheumatic drug prescription in early rheumatoid arthritis 2006 Aug OBJECTIVE: To characterise temporal trends and factors associated with the prescription of disease modifying antirheumatic drugs (DMARDs) at the initial consultation in early rheumatoid arthritis (RA). METHODS: Data from 2584 patients with early RA at 19 hospitals were extracted from the Swedish Rheumatoid Arthritis Register for the period 1997-2001. Disease characteristics and DMARD prescription at first consultation with the rheumatologist were investigated using cross tabulation and logistic regression. RESULTS: DMARD prescriptions, particularly for methotrexate, increased from 1997 to 2001 independently of patient characteristics. Stratification by hospital type showed that patients in district hospitals were less likely to be prescribed DMARDs than those in university hospitals (adjusted odds ratio (OR) = 0.53 (95% confidence interval (CI) 0.40 to 0.69), p<0.001), independently of confounding factors. Association of the DAS28 with the likelihood of DMARD prescription was greater among patients attending district hospitals (OR = 1.65 (1.34 to 2.02), p<0.001) than those at university hospitals (OR = 1.23 (1.07 to 1.41), p = 0.003) and county hospitals (OR = 1.34 (1.01 to 1.63), p = 0.003). Interaction testing indicated that the difference was significant (p = 0.007). CONCLUSIONS: Temporal trends in DMARD prescription indicate an increasingly aggressive approach to disease management among Swedish rheumatologists. However, the association of hospital type with DMARD prescription suggests that the adoption of research findings in clinical care varies considerably.
15708879 Cost effectiveness of etanercept (Enbrel) in combination with methotrexate in the treatmen 2005 Aug OBJECTIVE: To estimate the cost effectiveness of combination treatment with etanercept plus methotrexate in comparison with monotherapies in patients with active rheumatoid arthritis (RA) using a new model that incorporates both functional status and disease activity. METHODS: Effectiveness data were based on a 2 year trial in 682 patients with active RA (TEMPO). Data on resource consumption and utility related to function and disease activity were obtained from a survey of 616 patients in Sweden. A Markov model was constructed with five states according to functional status (Health Assessment Questionnaire (HAQ)) subdivided into high and low disease activity. The cost for each quality adjusted life year (QALY) gained was estimated by Monte Carlo simulation. RESULTS: Disease activity had a highly significant effect on utilities, independently of HAQ. For resource consumption, only HAQ was a significant predictor, with the exception of sick leave. Compared with methotrexate alone, etanercept plus methotrexate over 2 years increased total costs by 14,221 euros and led to a QALY gain of 0.38. When treatment was continued for 10 years, incremental costs were 42,148 euros for a QALY gain of 0.91. The cost per QALY gained was 37,331 euros and 46,494 euros, respectively. The probability that the cost effectiveness ratio is below a threshold of 50,000 euros/QALY is 88%. CONCLUSION: Incorporating the influence of disease activity into this new model allows better assessment of the effects of anti-tumour necrosis factor treatment on patients' general wellbeing. In this analysis, the cost per QALY gained with combination treatment with etanercept plus methotrexate compared with methotrexate alone falls within the acceptable range.
16503951 Pneumonitis associated with leflunomide: a profile of New Zealand and Australian reports. 2006 Mar BACKGROUND: Pneumonitis has very rarely been observed in patients taking leflunomide in clinical trials. Evidence is emerging that it is more frequent in clinical practice. AIM: The aim of this study was to investigate voluntary reports of suspected respiratory reactions to leflunomide held by the New Zealand Pharmacovigilance Centre (NZPhvC) and the Australian Adverse Drug Reactions Unit (ADRU) to ascertain if they fulfilled the criteria for pneumonitis and to define characteristics of this reaction. METHOD: Reports of respiratory adverse reactions attributed to leflunomide and received by the NZPhvC and the ADRU were analysed to identify those that were likely to be pneumonitis based on the criteria of Searles and McKendry. Features of these reports were examined to provide further information about this adverse reaction. RESULTS: The NZPhvC and the ADRU received 14 reports considered to be pneumonitis occurring in patients taking leflunomide. Two case reports fulfilled the Searles and McKendry criteria for definite or probable hypersensitivity pneumonitis. The patients in the remaining reports had radiological evidence of pulmonary infiltrates, an acute respiratory illness and no evidence of precipitating infection. In two cases the patients were taking leflunomide alone; one improved when it was withdrawn. In the other 12 cases, patients were taking leflunomide in combination with methotrexate. In nine of these 12 patients pneumonitis occurred after leflunomide was added to methotrexate, usually within 12-20 weeks. One of the two patients who died had possible previous methotrexate pneumonitis. Leflunomide washout with cholestyramine was used to treat three patients, one with life-threatening illness, with good results. CONCLUSION: This case series supports observations that leflunomide can cause pneumonitis either as monotherapy or in combination with methotrexate. The case histories indicate that prompt recognition is important to avoid life-threatening disease and support the use of cholestyramine to remove leflunomide.
17163236 Methotrexate and hepatic toxicity in rheumatoid arthritis and psoriatic arthritis. 2006 BACKGROUND: We set out in this study to demonstrate the adverse effect profile of methotrexate when used in the treatment of rheumatoid arthritis (RA) and psoriatic arthritis (PsA) in a district general hospital population, and to investigate the effect of alcohol consumption in these patients. METHODS: A prospective evaluation of 550 RA patients and 69 PsA patients was undertaken, controlling for confounding factors. Systematically randomised patients were further analysed regarding alcohol consumption. A transaminase level of three times the upper limit of normal on two or more occasions was taken to indicate hepatic injury. RESULTS: Gastrointestinal disturbance was the predominant adverse effect in RA patients (9.8%); hepatic disturbance was the most frequent in PsA patients (14.5%). Both groups had hepatic enzyme elevation; PsA patients were at significantly greater risk of elevated transaminases than RA patients (14.5% vs 7.5%, respectively, chi2 = 4.017). Alcohol consumption did not correlate with hepatic injury (mean 5.15 vs 6.6 alcohol units/week consumed by RA and PsA patients, respectively). CONCLUSION: Our data show methotrexate-treated PsA patients have a higher incidence of hepatotoxicity compared with methotrexate-treated patients with RA. It is proposed that psoriatic patients may be inherently more susceptible to methotrexate hepatotoxicity than are rheumatoid patients.
16025972 [Comparative study on clinical efficacy of using methotrexate singly or combined with tota 2005 Jun OBJECTIVE: To observe the clinical efficacy of methotrexate (MTX) combined with total glucosides of Peony (TGP) on rheumatoid arthritis (RA). METHODS: Sixty-one RA patients were divided into 2 groups, 30 patients in the MTX group were only administered orally with MTX, while 31 patients in the combined treated group were treated with MTX plus TGP, the therapeutic course for both groups was 3 months. RESULTS: The total effective rate was 90%, 94%, 100% in the MTX plus TGP group, and 87%, 90%, 94% in the MTX group at 4, 8 and 12 weeks after treatment respectively, comparison of the therapeutic effect between the two groups showed insignificant difference (P > 0.05). The erythrocyte sedimentation rate (ESR) and the level of C-reactive protein were significantly decreased in both groups, but the decrement in the MTX plus TGP group was more than those in the MTX group. CONCLUSION: MTX plus TGP treatment is characterized by quick initiating, with stable clinical efficacy, few side effects and high compliance, it is more suitable for aged RA patients.
16519794 Enhanced expression of mRNA for nuclear factor kappaB1 (p50) in CD34+ cells of the bone ma 2006 Bone marrow CD34+ cells from rheumatoid arthritis (RA) patients have abnormal capacities to respond to tumor necrosis factor (TNF)-alpha and to differentiate into fibroblast-like cells producing matrix metalloproteinase (MMP)-1. We explored the expression of mRNA for nuclear factor (NF)kappaB in RA bone marrow CD34+ cells to delineate the mechanism for their abnormal responses to TNF-alpha. CD34+ cells were purified from bone marrow samples obtained from 49 RA patients and 31 osteoarthritis (OA) patients during joint operations via aspiration from the iliac crest. The mRNAs for NFkappaB1 (p50), NFkappaB2 (p52) and RelA (p65) were examined by quantitative RT-PCR. The expression of NFkappaB1 mRNA in bone marrow CD34+ cells was significantly higher in RA than in OA, whereas there was no significant difference in the expression of mRNA for NFkappaB2 and RelA. The expression of NFkappaB1 mRNA was not correlated with serum C-reactive protein or with the treatment with methotrexate or oral steroid. Silencing of NFkappaB1 by small interfering RNA abrogated the capacity of RA bone marrow CD34+ cells to differentiate into fibroblast-like cells and to produce MMP-1 and vascular endothelial growth factor upon stimulation with stem cell factor, granulocyte-macrophage colony stimulating factor and TNF-alpha without influencing their viability and capacity to produce beta2-microglobulin. These results indicate that the enhanced expression of NFkappaB1 mRNA in bone marrow CD34+ cells plays a pivotal role in their abnormal responses to TNF-alpha and, thus, in the pathogenesis of RA.
17105853 Evaluation of a modified ACR20 scoring system in patients with rheumatoid arthritis receiv 2006 Dec OBJECTIVE: To evaluate a modified American College of Rheumatology 20 (mACR20) scoring system for patients with rheumatoid arthritis. METHODS: The data were evaluated from one study on patients with methotrexate (MTX)-naive early rheumatoid arthritis (ERA) and another study on patients with DMARD-refractory late rheumatoid arthritis (LRA). For mACR20 scoring, acute-phase reactant measurements were excluded, and 20% improvement from baseline was determined by 2 or 3 of the 4 remaining ACR components. RESULTS: For full joint counts with data from patients with ERA, marked differences favoured 25 mg etanercept (ETN) over 10 mg ETN by using the unmodified ACR20 (69% v 55%), the mACR20(3 of 4) (63% v 49%) and the mACR20(2 of 4) (72% v 58%). An assessment of 28 joints showed similar findings. In the trial on patients with LRA, considerably more patients in both ETN groups achieved a clinical response compared with placebo by using the ACR20, the mACR20(3 of 4) and the mACR20(2 of 4), whether using full or 28 joint counts. The mACR20(3 of 4) and full joint counts with data on patients with ERA showed a marked difference between the MTX and 10 mg ETN groups (63% v 49%), which was not observed with the ACR20. CONCLUSION: Patterns of improvement indicated by mACR20 scores were consistent with standard ACR20 scores.
16834969 [Effects of traditional Chinese medicine for invigorating spleen to resolve dampness and d 2006 Jul OBJECTIVE: To observe the clinical effects of Xinfeng Capsules (XFC), a traditional Chinese medicine for invigorating the spleen to resolve dampness and dredging collaterals, on patients with rheumatoid arthritis (RA) and anemia, and to investigate its mechanism. METHODS: Forty patients with RA and anemia were divided into three groups: XFC-treated group (n=20), Tripterygium glycosides Tablets (TGT)-treated group (n=10) and methotrexate (MTX)-treated group (n=10). The patients in each group took corresponding medicine for three months. The response rates of the three groups were evaluated after treatment. The general symptoms and specific signs and symptoms of RA were observed before and after the treatment. The indexes of blood routine examination and some other laboratory indexes such as erythrocyte sedimentation rate (ESR), and blood levels of rheumatoid factor (RF), iron, C-reaction protein (CRP), immunoglobins (Ig), complements 3 and 4, tumor necrosis factor-alpha (TNF-alpha), interleukin-10 (IL-10) and erythropoietin (EPO) were all examined and compared before and after treatment. RESULTS: The total response rate in the XFC-treated group was similar to those both in the TGT-treated and MTX-treated groups. The effects on relieving specific symptoms of RA in the three groups were also similar. The ESR and serum levels of RF, CRP, IgG, IgA and IgM were all decreased after treatment as compared with those before treatment in the three groups, and there were no significant differences among those laboratory indexes in the three groups after treatment. The XFC displayed more obvious effects on improving the general symptoms of patients with RA and anemia, increasing the blood levels of hemoglobin, iron and IL-10, while decreasing the serum level of TNF-alpha and regulating the serum EPO level, as compared with those in the TGT-treated and MTX-treated groups. CONCLUSION: The XFC for invigorating the spleen to resolve dampness and dredging collaterals was developed on the basic principle of regulating spleen. It can obviously improve the symptoms and laboratory indicators of RA. Such effects may be related to maintaining the balance of cytokines, regulating the serum level of EPO and increasing the serum iron level in patients with RA and anemia.
17158431 Randomized phase 2 trial of anti-tumor necrosis factor therapy for cachexia in patients wi 2006 Dec BACKGROUND: Tumor necrosis factor (TNF) is an important mediator of cachexia, and its blockade prevents catabolism in animal models. However, little evidence shows that anti-TNF therapy is effective in treating cachexia in humans. OBJECTIVE: The main aim of this study was to investigate the effect of etanercept, a synthetic soluble TNF receptor, on body composition in patients with early rheumatoid arthritis (RA). DESIGN: Twenty-six patients were randomly assigned to 24 wk of treatment with etanercept or methotrexate; the latter is the first-line therapy for RA. Body composition, physical function, disease activity, systemic inflammation, and the circulating insulin-like growth factor (IGF) system were measured at baseline (week 0) and at follow-up (weeks 12 and 24). Twelve patients in each treatment group (9 F, 3 M) completed the study. RESULTS: Overall, no important changes in body composition were observed, despite a transient increase in IGF-I at week 12 (P < 0.01). However, the secondary analysis of those patients (6/treatment group) who gained weight during follow-up showed a significant effect of etanercept on the composition of the weight gained: 44% of weight gained in the etanercept group was fat-free mass, as compared with only 14% in the methotrexate group (P = 0.04). Etanercept and methotrexate were equally effective in controlling the disease and improving physical function. CONCLUSIONS: Anti-TNF therapy with etanercept is not superior to that with methotrexate for the treatment of rheumatoid cachexia over a period of 6 mo. However, TNF blockade seems to normalize the anabolic response to overfeeding and, if these findings are confirmed, may be useful in conditions characterized by anorexia and weight loss.
15550533 Cost effectiveness of adalimumab in the treatment of patients with moderate to severe rheu 2005 Jul BACKGROUND: Societal decision makers increasingly emphasise their need for evidence based economic analyses to make reimbursement decisions. OBJECTIVE: To analyse the cost utility of adalimumab, on both incremental cost and incremental quality adjusted life years (QALYs), versus traditional disease modifying antirheumatic drugs and the other tumour necrosis factor (TNF) antagonists suitable for submission to the Swedish LFN (Pharmaceutical Benefit Board). METHODS: Swedish unit costs and treatment guidelines from a lifetime perspective were implemented. A mathematical model, incorporating data from seven trials, simulated the experiences of 10 000 hypothetical patients with moderate to severe rheumatoid arthritis (RA). The primary outcome measure-QALYs-was derived from utility values calculated from a relationship between the Health Assessment Questionnaire (HAQ) Disability Index (DI) and Health Utility Index-III (HUI-3) from adalimumab trial results. The model followed the progression of HAQ-DI through a number of treatments in a sequence accounting for mortality, drug and monitoring costs, and other direct costs. RESULTS: When using ACR50 as a response threshold for determining successful treatment, adalimumab plus methotrexate showed the greatest number of QALYs gained (2.3 from one study and 2.1 from the pooled results of two trials). The etanercept plus methotrexate strategy yielded QALY gains similar to the pooled adalimumab results. Except for the infliximab strategy, the costs results were between 35 000 and 42 000, a range normally considered cost effective in other European countries. CONCLUSION: Adalimumab appears to be cost effective for the treatment of moderate to severe RA. The results suggest that adalimumab is at least as cost effective as other TNF antagonists.
16114981 Sulfasalazine: a review of its use in the management of rheumatoid arthritis. 2005 Sulfasalazine (salazosulfapyridine) [Azulfidine, Salazopyrin] is a well established disease-modifying antirheumatic drug (DMARD) used in the treatment of patients with rheumatoid arthritis. Clinical trials with sulfasalazine have used an array of measures of disease activity, such as the number of tender and swollen joints, Ritchie articular index (RAI) and erythrocyte sedimentation rate (ESR). In randomised, double-blind, placebo-controlled trials, sulfasalazine was associated with statistically significant benefits for various measures of disease activity, according to results of individual trials and/or meta-analysis. Sulfasalazine was associated with broadly similar efficacy to that of various other DMARDs in several randomised, double-blind, comparative trials. Promising results have also been demonstrated with sulfasalazine in combination with other DMARDs (e.g. methotrexate and hydroxychloroquine) in patients with early rheumatoid arthritis and in those with more established disease. Sulfasalazine was generally well tolerated in clinical trials, the most frequently reported adverse effects being adverse gastrointestinal effects, headache, dizziness and rash; myelosuppression can also occur. Sulfasalazine has a relatively short lag time until its onset of action and is often considered to be among the more efficacious traditional DMARDs. Based on considerations of safety, convenience and cost, many rheumatologists (particularly outside of the US) select sulfasalazine as initial therapy, although preferred first-line treatment options vary between countries.
15645233 Influence of serum folic acid levels on plasma homocysteine concentrations in patients wit 2006 Jan The purpose of this study was to investigate whether negative effects of methotrexate (mtx) on blood homocysteine (hmc) levels can be prevented with the replacement of folic acid. 42 female patients with rheumatoid arthritis (RA) were studied. Patients were separated into two groups according to their treatment status with mtx (group I: 27 patients taking mtx and folic acid; group II: 15 patients not using mtx). The level of hmc was found to be 6.3+/-2.4 micromol/l in group I and 7.87+/-3.2 micromol/l in group II (p>0.05). Folic acid levels of group I and II were found to be 21.3+/-15.9 ng/ml and 8.41+/-2.86 ng/ml respectively (p<0.001). There was a statistically-significant correlation between age and hmc levels (r=0.386, p=0.012). Negative statistically-significant correlations were observed between folic acid and hmc levels. The effects of mtx on hmc can be prevented with the replacement of folic acid.
16778342 Leflunomide-induced pneumonitis in a patient with rheumatoid arthritis. 2006 Leflunomide is a disease-modifying antirheumatic drug (DMARD) that has been available in Japan since August 2003. Leflunomide-induced interstitial pneumonitis has not been reported as an adverse effect in other countries. We report a suspected case of leflunomide-induced interstitial pneumonitis. A 77-year-old woman with rheumatoid arthritis and a history of methotrexate-induced pneumonitis developed sudden-onset dyspnea on exertion about 2 months after the administration of leflunomide. She maintained a high concentration of an active metabolite of leflunomide for more than 3 weeks after withdrawal of the drug. She did not respond to treatment and died. Leflunomide must be administered with caution to patients with a history of interstitial pneumonitis or drug-induced pneumonitis. If leflunomide-induced pneumonitis is suspected, the plasma concentration must be immediately checked, along with elimination and withdrawal of the medication.
16206360 Deaths following methotrexate overdoses by medical staff. 2005 Oct Methotrexate (MTX) is an effective disease modifying antirheumatic drug (DMARD) with a relatively safe profile, and it is widely used to treat neoplastic diseases and dermatologic and rheumatologic disorders. As indications for use of MTX increase, more accidental overdoses are noted to occur. Typical problems include deficiencies in labeling, instructions, or packaging, as well as erroneous use. We describe 5 fatal cases of repeated oral overdose of MTX prescribed by physicians in the treatment of rheumatoid arthritis to focus attention on the design of the underlying system and the organizational practices as sources of problems.
16905577 Differential effect of methotrexate on the increased CCR2 density on circulating CD4 T lym 2007 Feb OBJECTIVES: To evaluate the effect of orally administered methotrexate (MTX) on the density of CC chemokine receptor 2 (CCR2) and CXC chemokine receptor 3 (CXCR3) on circulating monocytes, and the coexpression of CXCR3 and CCR2 on CD4 T lymphocytes in patients with active chronic rheumatoid arthritis. METHODS: All 34 patients with rheumatoid arthritis fulfilled the 1987 American Rheumatism Association criteria and were followed for 16 weeks after starting MTX. Peripheral blood mononuclear cells were analysed for CCR2 and CXCR3 density by three-colour flow cytometry before initiation of MTX and at week 12. RESULTS: 22 (65%) patients were non-responders, 12 (35%) patients responded to MTX by American College of Rheumatology (ACR)20% criteria, and 8 (24%) of these patients responded by ACR50%. In patients with active rheumatoid arthritis before starting MTX, CCR2 density on circulating monocytes, CD4(+) CXCR3(+) and CD4(+) CXCR3(-) T lymphocytes was increased compared with controls. During 12 weeks of MTX treatment, the CCR2 density on monocytes decreased significantly in the ACR50% group but not in the ACR20% and non-responder groups. The increased CCR2 density on CD4(+) CXCR3(+) and CD4(+) CXCR3(-) T lymphocytes was unaffected by the reduction in disease activity measured in relation to MTX treatment. The percentage of both monocytes and CD4(+) CXCR3(+) and CD4+ CXCR3(-) T lymphocytes among the peripheral circulating mononuclear cells did not change during MTX treatment. CONCLUSIONS: Active chronic rheumatoid arthritis is characterised by enhanced CCR2 density on circulating monocytes and CD4(+) CXCR3(+) and CD4(+) CXCR3(-) T lymphocytes. During MTX treatment, a decrease in CCR2 density on monocytes in the ACR50% responder group was associated with decreased disease activity. The increased CCR2 density on CD4(+) CXCR3(+) and CD4(+) CXCR3(-) T lymphocytes was uninfluenced by MTX and disease activity.
15996057 Longterm safety, efficacy, and radiographic outcome with etanercept treatment in patients 2005 Jul OBJECTIVE: To evaluate safety, efficacy, and radiographic progression in patients with early rheumatoid arthritis (RA) undergoing longterm treatment with etanercept. METHODS: Patients with early RA (disease duration of 3 years or less) who had completed a 2-year efficacy study comparing etanercept and methotrexate (MTX) were followed in an extension where they received 25 mg etanercept twice weekly. Safety was summarized descriptively and compared with data from the efficacy study. Efficacy and radiographic progression were assessed using American College of Rheumatology response criteria, disease activity scores, and Total Sharp Score (TSS). RESULTS: Rates of serious adverse events and serious infections did not increase with longterm exposure to etanercept, and were similar to rates reported for the blinded portion of the efficacy study. Efficacy was sustained in patients who completed 5 years of etanercept treatment at the time of this report (N = 201), even in those who decreased or discontinued use of MTX or corticosteroids. No radiographic progression (change in TSS < or = 0) was seen in 55% of patients with 5-year radiographs; negative change (TSS < 0) was seen in 11%. CONCLUSION: Etanercept treatment in patients with early RA was generally well tolerated for up to 5 years. The results indicate sustained efficacy and decreased rate of radiographic progression. The rate of radiographic progression was low compared with other studies, emphasizing the benefit gained in patients with early aggressive RA who undergo longterm treatment with etanercept.
15702101 Methotrexate and oral ulceration. 2005 Jan 22 Methotrexate is well established in the drug treatment of various neoplastic diseases. More recently it has become increasingly used as a once-weekly, low-dose treatment of disorders such as psoriasis and rheumatoid arthritis. Clinical trials have shown its effectiveness in these conditions and it is likely that dentists will encounter patients taking this drug in general dental practice. Oral ulceration can occur as a side effect of methotrexate therapy. This may be due to lack of folic acid supplementation or overdosage due to confusion regarding its once-weekly regime. Illustrations of these problems, which have initially presented in a dental setting, are given. Important drug interactions of methotrexate relevant to dentistry are discussed.
17129076 Cost effectiveness of tumour necrosis factor-alpha inhibitors as first-line agents in rheu 2006 BACKGROUND AND OBJECTIVE: Rheumatoid arthritis (RA) is an autoimmune disease with an unknown aetiology that results in >9 million physician visits and >250 000 hospitalisations per year in the US. Tumour necrosis factor-alpha (TNFalpha) inhibitors are effective agents in treating RA; however, their cost effectiveness as first-line agents has not been investigated. This study aimed to examine the cost effectiveness of using TNFalpha inhibitors (both as monotherapy and in combination with methotrexate) as first-line agents versus methotrexate (monotherapy) from a payer perspective. METHODS: A Markov model was developed utilising a discount rate of 3% per annum, a cycle length of 1 year and a lifetime time-horizon for a hypothetical cohort of US females aged 55-60 years who had been diagnosed with RA. The source of data for predicted probabilities, expected mortality rates and treatment costs in year 2005 US dollars (drug, toxicity, monitoring and hospitalisation) was from the literature. These costs are assigned in 5-year cycles (calculated from initial 1-year estimates) along with the effect on quality-adjusted life-years (QALYs), which were calculated using the Health Assessment Questionnaire score. Univariate sensitivity analyses were conducted on all relevant parameters. RESULTS: Adalimumab, etanercept, adalimumab plus methotrexate and infliximab plus methotrexate had incremental cost-effectiveness ratios (ICERs) versus methotrexate monotherapy of $US63 769, $US89 772, $US194 589 and $US409 523 per QALY, respectively. When taking into consideration age at diagnosis, the ICER for etanercept ranged from $US84 129 to $US96 225 per QALY. In considering males for the base-case age at diagnosis, the ICER for etanercept versus methotrexate was $US85 100 per QALY. The average lifetime cost across all treatment arms in a woman diagnosed between 55 and 60 years of age was $US211 702. CONCLUSION: While these ICERs cannot be used to directly compare one biological agent with another since there are no comparative trials, they do provide a valid comparison versus methotrexate as first-line agents. Depending where the cost-effectiveness threshold is drawn (i.e. whether it is considered to be $US50 000 or $US100 000 per QALY), etanercept and adalimumab may be considered relatively cost-effective first-line treatments for RA compared with methotrexate monotherapy.
16583484 Mycobacterium marinum arthritis mimicking rheumatoid arthritis. 2006 Apr Mycobacterium marinum is an atypical mycobacterium found in salt and fresh water. M. marinum infection occurs following skin trauma in fresh or salt water and usually presents as a localized granuloma or sporotrichotic lymphangitis. It rarely affects the musculoskeletal system. We describe a patient who presented with subcutaneous nodules and an inflammatory arthritis that was thought to be rheumatoid arthritis, and was treated as such with corticosteroids, methotrexate, and anti-tumor necrosis factor-alpha therapy, with worsening of his arthritis.
16761535 Placental umbilical cord whole blood transfusion to combat anemia in the background of adv 2006 Rheumatoid arthritis is the commonest form of inflammatory arthritis and affects about 1-3% of the population in the West and even more in the developing world due to the compounded factors of late detection and inadequate treatment in the overall background of poverty, deprivation, and improper macro and micronutrients in the diet in a sizeable segment of the population. Nearly 90% of patients with aggressive disease will become clinically disabled within 20 years. Furthermore, in patients with severe disease or extra-articular symptoms, mortality is equal to that for patients with triple artery coronary artery disease or Stage IV Hodgkin's lymphoma. Anemia is a very common comorbidity of rheumatoid arthritis. Anemia in rheumatoid arthritis is caused by various factors, for instance, cytokine impact of the advanced arthritic process on the host, or lack of proper nutrition and essential micronutrients in the diet, or coexistent helminthiasis, and/or impact of antiarthritic drugs on the host system, i.e., high steroid induced gastritis or ulcerations in gastric mucosa or subclinical or clinical hepatitis due to methotrexate or salazopyrin effects on bone marrow, only to name a few. Other pre-existing or compounding gastrointestinal problems, which alter the available iron stores or cause bone marrow dysfunction, may also help in adding to an anemic condition. If the anemia is 8 g/dl or less, blood transfusion or erythropoietin injection with adequate hematinic reserve is effective in normal situations, but is not that effective in anemia with a chronic disease background like rheumatoid arthritis. Cord blood, because of its rich mix of fetal and adult hemoglobin, high platelet and white blood cell (WBC) counts, and a plasma filled with cytokine and growth factors, as well as its hypo antigenic nature and altered metabolic profile, has all the potential of a real and safe alternative to adult blood transfusion. Seventy-eight units (42 ml -136 ml mean 80.6 ml +/- 3.6 ml SD, median 82.4 ml, mean packed cell volume 48.2 +/- 2.1 SD, mean percent hemoglobin concentration 16.4 g/dl +/- 1.5 g/dl SD) of placental umbilical cord whole blood was transfused (from 1 April 1999 to April 2005) after lower uterine cesarean section (LUCS) from consenting mothers to 28 informed consenting patients with advanced rheumatoid arthritis who had plasma hemoglobin of 8 g/dl or less. After collection, the blood was immediately transfused following the standard adult blood transfusion protocol. Each case was passed through the institutional ethical committee. The patients received two to six units of freshly collected placental umbilical cord blood without encountering any clinical, immunological or non-immunological reactions. Three days after completion of the transfusion of placental umbilical cord blood, the peripheral blood hematopoietic stem cell (CD34) estimation revealed a rise from the pretransfusion base level (.09%), varying from 2.03 to 23%, which returned to base level in most of the cases at the three-month CD34 re-estimation, without provoking any clinical graft vs host reaction in any of the patients.
