17437163 | Influence of methotrexate dose on its efficacy and safety in rheumatoid arthritis patients | 2007 | The optimal methotrexate dose differs between rheumatoid arthritis (RA) patients, and dose-escalation strategies also differ among rheumatologists. By taking advantage of the heterogeneous methotrexate dosing that occurs among Japanese rheumatologists, we analyzed the efficacy and safety of different methotrexate doses. A large observational cohort of RA patients, IORRA, was established in 2000. A dataset from April 2003 that included 4578 RA patients was used for a cross-sectional analysis, while a dataset of 1649 patients who received methotrexate from October 2000 to October 2005 was used for a longitudinal analysis. The cross-sectional analysis included 12 rheumatologists who prescribed methotrexate to more than 60 patients. Mean methotrexate dose ranged widely (4.8-9.0 mg/week) among rheumatologists with a significant positive relationship between average methotrexate dose and the percentage of patients with Disease Activity in 28 Joints (DAS28) scores below 3.2. During the longitudinal analysis, both methotrexate prescription frequency and the average dose prescribed by 16 rheumatologists increased. Overall disease activity as assessed by DAS28-area under the curve (AUC) and disability progression as assessed by Japanese version of the Health Assessment Questionnaire (JHAQ)-slope inversely correlated with the extent of methotrexate use. This study demonstrated that extensive methotrexate use effectively suppressed RA disease activity and inhibits disability progression. In addition, we have found that it is critical to pay attention to patient-reported adverse reactions. | |
16982117 | [Aspergillosis in systemic diseases treated with steroids and/or immunosuppressive drugs: | 2006 Nov | This is a multicentric retrospective study of aspergillosis in patients treated by corticosteroids and/or immunosuppressive drugs for systemic diseases and a review of the literature. Nine patients, 5 men and 4 women, mean age of 62.8 years old were included among which Horton's diseases (3 cases), systemic lupus erythematosus (2), polymyositis (1), microscopic polyangiitis (1), idiopathic thrombocytopenic purpura (1), rheumatoid polyarthritis (1). Aspergillosis occurred in average 28.4 month after the diagnosis of systemic disease, and 28 months after the beginning of its treatment: corticosteroids in all cases, at a dose of 50.8 mg/day (equivalent prednisone) in average, cyclophosphamide (2 cases), methotrexate (1), intravenous immunoglobulins (1), leflunomide (1). All cases were invasive or chronic pulmonary aspergillosis located in the lungs (6 cases), or in the brain (3). Revealing symptoms were mild and non specific. Lymphopenia was severe in most cases, in average 472 lymphocytes/mm3 and 283 CD4+/mm3. The diagnosis was confirmed 20.75 days after the first symptoms in invasive aspergillosis, and 18.5 months in the chronic pulmonary cases, by cultures in 7 cases (broncho-alveolar lavage: 4; cerebral biopsy: 3), and direct microscopy examination of broncho-alveolar lavage in 2 cases. Specific serology was positive in 4 cases. Patients were treated by voriconazole (4 cases), itraconazole (2), amphotericin B (1), association of caspofungin and voriconazole (1), successive voriconazole and itraconazole (1). Six patients recovered from aspergillosis with 10.8 months of following time, 3 patients died a few days after confirmation of the diagnosis. Fifty-four cases of the literature are analysed. | |
18041889 | Abatacept: a novel treatment for moderate-to-severe rheumatoid arthritis. | 2007 Dec | Rheumatoid arthritis is a chronic autoimmune disease that often leads to functional disability and reduced quality of life. The pathogenesis of synovial inflammation that is associated with this disease is thought to result from T-cell activation. To become fully activated, T cells require an antigen-specific signal through the T-cell receptor and a second signal through a costimulatory receptor. Abatacept is the first drug in a new class of disease-modifying antirheumatic drugs (DMARDs) known as selective costimulation modulators. Costimulation modulators block the second signal and decrease T-cell activation. Abatacept has been approved by the United States Food and Drug Administration for reducing signs and symptoms, inducing major clinical response, slowing the progression of structural damage, and improving physical function in adults with moderate-to-severe active rheumatoid arthritis who have had an inadequate response to at least one other DMARD, such as methotrexate or tumor necrosis factor (TNF)-alpha inhibitors. Randomized controlled trials have shown that abatacept improves both clinical outcomes and health-related quality of life in patients who have had an inadequate response to other DMARDs. Abatacept has been shown to be well tolerated. In clinical trials, however, abatacept treatment was associated with a higher rate of infections compared with placebo. This finding was compounded when abatacept was used with TNF-alpha inhibitors; thus, this combination should be avoided. Abatacept appears to be a useful treatment option for patients with rheumatoid arthritis who have previously failed other DMARDs. However, additional clinical trials evaluating its long-term effect on patient safety and disease outcomes are needed. | |
18674945 | Herpes zoster in patients taking TNFalpha antagonists for chronic inflammatory joint disea | 2008 Oct | OBJECTIVE: To assess the rate of occurrence and outcomes of herpes zoster in patients taking TNFalpha antagonists. METHODS: Retrospective review of the medical records of 300 patients who received TNFalpha antagonists to treat chronic inflammatory joint disease. RESULTS: We identified 9 (9/300, 3%) patients who experienced herpes zoster, 6 women and 3 men, with rheumatoid arthritis (n=7) or ankylosing spondylitis (n=2). The drug was infliximab in 4 patients, adalimumab in 2 patients, and etanercept in 3 patients, including 2 patients with a prior history of infliximab therapy (for 12 and 36 months, respectively). Mean treatment duration at the occurrence of herpes zoster was 27 months (range, 6-42 months). DISCUSSION: Glucocorticoid therapy (n=7) and methotrexate therapy (n=6) were the only risk factors identified in our study. Mean follow-up was 26 months. All 9 patients achieved a full recovery with antiviral treatment and interruption of the TNFalpha antagonist. One patient experienced a recurrence after resuming TNFalpha antagonist therapy. CONCLUSION: The scant data in the literature suggest a higher risk of herpes zoster with anti-TNFalpha antibodies than with the soluble receptor. The role for concomitant treatments (glucocorticoids and methotrexate) should be taken into account. | |
17200802 | Lymphomatoid granulomatosis and diffuse alveolar damage associated with methotrexate thera | 2007 Sep | We report on a patient of rheumatoid arthritis (RA) who sequentially developed an axillary mass and a fatal interstitial pneumonia during a 2-year course of methotrexate (MTX) therapy. Autopsy revealed a systemic lymph node involvement and the diagnosis of Epstein-Barr virus (EBV)-related lymphoproliferative disease (LPD) with the features of lymphomatoid granulomatosis was made. The lung tissue specimens revealed a typical diffuse alveolar damage (DAD), and small nodules consisting of atypical B lymphocytes showing positive staining for EBV were sparsely recognized only in basal lungs. This is the first report of a RA patient receiving MTX therapy sequentially developing MTX-associated lymphomatoid granulomatosis and DAD. | |
17551383 | Strongyloides stercoralis hyperinfection in a patient with rheumatoid arthritis after anti | 2007 Jun | Strongyloidiasis is epidemic in tropical and subtropical regions where the regional prevalence may exceed 25%. In the United States, highest infection rates are found in immigrants. Many infected individuals are asymptomatic, whereas others may have mild and nonspecific cutaneous, intestinal, and pulmonary symptoms. Strongyloides stercoralis may remain as a dormant infection, but replication and dissemination can be fatal in immunocompromised patients. We report on a 63-year-old native Filipino man with a history of rheumatoid arthritis who developed Escherichia coli sepsis, filariform larvae characteristic of S. stercoralis bronchoalveolar lavage, and adult respiratory distress syndrome 3 weeks after he presented with vague gastrointestinal symptoms. We believe that the addition of a tumor necrosis factor (TNF)-alpha inhibitor to his treatment with prednisone and methotrexate for rheumatoid arthritis further suppressed his cellular immunity leading to hyperinfection and life-threatening S. stercoralis infection. This is another, often latent, infection that should be considered in patients in or from endemic areas before institution of antitumor necrosis factor therapy. | |
16945726 | An unusual presentation of methotrexate-induced B-cell lymphoma of the metacarpophalangeal | 2006 Sep | We report a unusual presentation of B-cell lymphoma in the chronically inflamed synovium of a 64-year-old man with an 18-year history of rheumatoid arthritis that was treated with methotrexate. | |
16969149 | Removal of methotrexate by peritoneal dialysis and hemodialysis in a single patient with e | 2006 Sep | BACKGROUND: Although methotrexate is highly bound to albumin, it is thought to be removed by hemodialysis and not by peritoneal dialysis. We are not aware of any direct comparison in the same patient. CASE REPORT/METHODS: A 60-year-old patient on continuous ambulatory peritoneal dialysis was admitted to the East Alabama Medical Center for stomatitis and pancytopenia after being given 10 mg of methotrexate for his rheumatoid arthritis. Measurements of total methotrexate levels were made before, during, and after sequential peritoneal and hemodialysis treatments. RESULTS: We found that the clearance of methotrexate measured in the dialysate was equal in the first hour of dialysis for both types of dialysis, although serum levels were markedly lower in hemodialysis compared to peritoneal dialysis. CONCLUSION: Methotrexate was cleared by peritoneal dialysis in the first hour of an exchange and was not associated with a rebound in serum levels. Hemodialysis was associated with lower serum levels; however, there was also a significant rebound 2 hours after the procedure ended. Since neither procedure was able to preclude the death of the patient, other more effective means of methotrexate elimination should be employed. | |
17435840 | [Anakinra, a recombinant human IL-1 receptor antagonist, in clinical practice. Outcome in | 2007 Jan | OBJECTIVE: We evaluated both the efficacy and safety of anakinra in daily routine rheumatoid arthritis clinical practice. METHODS: We studied 60 cases, including patients with previous anti-TNFalpha exposure, treated with anakinra (100 mg/daily s.c.) in combination with methotrexate (7.5-10 mg/week i.m.) or leflunomide (20 mg/die) in a two year observational study. Efficacy measures were assessed using the American College of Rheumatology (ACR) response criteria. Safety was evaluated according to a modified World Health Organization adverse reaction term dictionary. RESULTS: At week 14, ACR 20% response criteria have been fulfilled by 53 (91.3%) out of 58 patients, 51 (87.9%) of them achieving also an ACR 50%and 15 (25.8%) an ACR 70%response. Thirteen patients touched 102 weeks of treatment: ACR 20% response was achieved in 92.3%, while ACR 50% and ACR 70% were respectively found in 84.6% and 38.4% of the cases. The mean decrease in HAQ score was 0.38, p<0.001. Of the 16 patients who were previously treated with anti-TNFalpha blockers, 81.2% responded to anakinra. There was no significant difference in the ACR response between groups with and without previous anti-TNFalpha exposure. Seventeen patients (28.3%) stopped anakinra because of side-effects (5%) or failure to respond (23.3%). Only 4 cases of pulmonitis, of which 2 have been hospitalised, and 1 case with tuberculosis (previously treated with infliximab) were observed. CONCLUSIONS: Our clinical experience confirms that anakinra is effective and safe in the treatment of rheumatoid arthritis. Anakinra seems also useful in patients with previous anti-TNFalpha blockers failures. Even though major adverse events were rare, clinicians should be aware of such a possibility. | |
18341834 | [Efficacy and security of tumor necrosis factor antagonists in the treatment of rheumatoid | 2008 Feb 16 | In the last decade, tumor necrosis factor (TNF) antagonists had supposed an important therapeutic advance in the treatment of patients with rheumatoid arthritis (RA) in both early and established RA. Three agents currently available--infliximab, etanercept, and adalimumab--have been designed to modify the biologic effects of TNF. Infliximab and adalimumab are monoclonal antibodies, whereas etanercept is a soluble protein, with different pharmacokinetic and pharmacodynamic properties, conditioning some possible adverse effects. Although comparative studies are not available, the 3 drugs have demonstrated efficacy and security, with a better quality of life of patients with RA. Infliximab, etanercept and adalimumab have been proved alone and in combination with methotrexate, with a better therapeutic, clinical, radiological and functional response in the group under combined therapy. Both clinical trials and post-market experience have demonstrated the security of these drugs, minimizing the risks with an adequate selection of patients. | |
18211615 | Treatment of pregnant and non-pregnant rheumatic patients: a survey among Dutch rheumatolo | 2008 Feb | BACKGROUND: The aim of this study was to explore, among Dutch rheumatologists, aspects such as attitude towards guidelines, pharmacotherapy and information needs in the treatment of pregnant as well as non-pregnant rheumatoid arthritis (RA) patients. METHODS: Fifteen rheumatologists from nine different hospitals were interviewed by means of a semi-structured interview. Questions addressing attitude towards guidelines, pharmacotherapy preferences and information needs with respect to the pregnant and non-pregnant patient were asked. The analysis will be based on descriptive statistics. RESULTS: Guidelines are used by almost half of the hospitals with respect to pregnant RA patients and by all hospitals for RA patients in general. With respect to pregnant women, nine respondents preferred stopping the medication as soon pregnancy is known. When treating RA patients, in general sulfasalazine and methotrexate would be drugs of first choice. Information is found in international and national books and guidelines. CONCLUSION: Dutch rheumatologists are of the view that there is sufficient information on the treatment of RA in pregnant women or women wishing to become pregnant, except for safe use of medication during pregnancy. In the future, pregnancy risk categorization should be updated and discussed regularly. This should be based on more recent literature and experience. A good monitoring system for following all young patients with a rheumatic disease should be set up as a first step to collect more information on the safe use of medication during pregnancy. | |
18092260 | The number needed to treat for adalimumab, etanercept, and infliximab based on ACR50 respo | 2007 Nov | OBJECTIVE: To compare the efficacy of adalimumab, etanercept, and infliximab in patients with established rheumatoid arthritis (RA) taking concomitant methotrexate (MTX) by calculating the number needed to treat (NNT) using three different methods. METHODS: A systematic literature search of the Cochrane Library, MEDLINE, and EMBASE was conducted from inception to 30 June 2006. Two pairs of investigators, a Danish and a Swedish pair, independently conducted a structured literature review. The reviewers selected any published randomized, double-blind, MTX controlled study of adalimumab, etanercept, and infliximab, presenting the American College of Rheumatology 50% response (ACR50) after 12 months in RA patients with a mean disease duration of at least 5 years. The two review groups independently extracted the estimates necessary to calculate the NNT. RESULTS: The reviewers consistently selected the same three randomized, controlled trials (RCTs), one for each of the drugs, and extracted equal data for the number of patients completing the 12-month intervention, and the corresponding number of ACR50 responding patients after therapy. Some baseline differences were noted: patients in the etanercept trial had a shorter disease duration and did not receive MTX prior to inclusion; patients in the adalimumab study had lower Health Assessment Questionnaire (HAQ) scores. The calculated NNTs varied slightly depending on the method used. The fully adjusted NNTs (95% confidence intervals) for adalimumab, etanercept, infliximab standard dosage and infliximab double dosage were 4 (3-6), 4 (3-6), 8 (4-66), and 4 (3-11) patients, respectively. CONCLUSION: This study indicates equal efficacy of the three anti-tumour necrosis factor (TNF) therapies. | |
17451848 | [Pancytopenia related to low-dose methotrexate: study of five cases and review of the lite | 2007 Sep | PURPOSE: The aim of this study is to report personal experience of pancytopenia related to low-dose methotrexate and to review the literature. METHODS: We included retrospectively all cases of pancytopenia related to low-dose methotrexate (<25 mg/week), followed between January 1997 and December 2006, in the university hospital of Strasbourg, France. RESULTS: Five women, mean age 75.6 years, were included in the present study. Clinical manifestations included: symptomatic anemia (n=4), infection (n=3) and hemorrhagic manifestations (n=2); one patient had no feature. Mean hemoglobin concentration was 8,8 g/dl; mean white cell and platelet counts were 1,500 /mm(3) and 16,000 /mm(3), respectively. Potential risk factors were identified in all patients: renal failure and low serum albumin levels (n=5), anti-inflammatory drug intake (n=2), folate deficiency (n=4) and cobalamin deficiency (n=1). One patient died of septic and hemorrhagic cerebral complications. CONCLUSION: Pancytopenia related to tow-dose methotrexate is a rare but life-threatening disorder. Search and prevention of potential risk factors are required in all patients; determination of MTHFR genotype may be of several interests as folate supplementation. | |
16634363 | The world of biologics. | 2006 | In March 2002 the National Institute for Health and Clinical Excellence (NICE) published guidelines for the use of anti-TNF therapy for patients with rheumatoid arthritis (RA). The guidelines recommended that all RA patients treated with these drugs should be enrolled on a national register which had been established by the British Society for Rheumatology (the BSRBR). A comparison cohort of RA patients treated with traditional disease modifying drugs (DMARDs) is also being recruited. The main role of the BSRBR is to study the long-term safety of biologic drugs. Up to the end of March 2005, 9508 patients with RA had been enrolled on the BSRBR. Four thousand, three-hundred and six had been treated with etanercept, 3561 with infliximab, 1500 with adalimumab and 141 with anakinra. With regards to anti-TNF drugs, 79% remained on their original drug at six months, 65% of whom could be classified as responders. Co-prescription with methotrexate was associated with a 70% response rate. Patients with a high baseline level of disability were less likely to respond. Overall the rates of serious infection were not increased in the anti-TNF versus the comparison cohort. However the rates of skin and soft tissue infection and of intracellular infections (eg, salmonella, listeria, legionella) were increased. There were 11 cases of tuberculosis (seven extra-pulmonary). There was concern about the high mortality rates among patients with baseline pulmonary fibrosis treated with anti-TNF therapy. It is unclear whether this is related to the drug or to the underlying disease. The rates of malignancy and mortality were not increased compared to the DMARD treated group in the short term. Further follow-up is needed to determine the long term safety of these drugs. | |
17878395 | Intramuscular methotrexate-induced aseptic meningitis. | 2007 Nov | OBJECTIVE: To report a case of aseptic meningitis induced by intramuscularly administered methotrexate in a patient with rheumatoid arthritis. CASE SUMMARY: A 62-year-old male presented on 3 separate occasions with symptoms consistent with aseptic meningitis: 2 required hospitalization and 1 was noted during a subsequent ambulatory care visit. Prior to the first episode, the methotrexate dose ranged between 17.5 mg and 20 mg given once weekly over 5 years, 11 months. One month before the patient's first admission, the dose was increased to 22.5 mg. Symptoms on presentation included headache, neck stiffness, and fever. Cerebrospinal fluid testing indicated pleocytosis and low glucose level. Methotrexate was discontinued but was restarted 2 weeks after hospital discharge at the same dose and resulted in a second hospitalization for aseptic meningitis. Upon discharge from the second hospitalization, methotrexate was withheld. After a 2 month withdrawal period and rechallenge, the symptoms returned within 3 days. The drug was then discontinued. DISCUSSION: Methotrexate-induced aseptic meningitis has been reported in the literature; however, in those cases, the effect occurred only when methotrexate was given via the intrathecal route. We identified 7 relevant articles via a search of MEDLINE, International Pharmaceutical Abstracts, and EMBASE (1970-August 3, 2007): 3 were review articles, 2 were case series, and 2 were case reports. All of the series and reports involved patients with leukemia. The available literature suggests that aseptic meningitis is associated with long-term use of methotrexate or recent dose escalation. A definitive mechanism for methotrexate-induced aseptic meningitis is not known. The Naranjo probability scale indicates a probable relationship between the development of the condition and the methotrexate use in our patient. CONCLUSIONS: Aseptic meningitis has been previously associated with intrathecal use of methotrexate. Our report describes the first case of aseptic meningitis that occurred in a patient being treated with intramuscular methotrexate. | |
18173917 | Adalimumab plus methotrexate or standard therapy is more effective than methotrexate or st | 2007 Nov | OBJECTIVES: Fatigue is an important systemic symptom of rheumatoid arthritis (RA) but has rarely been evaluated consistently after initiation of treatment in RA patients. This study examined the effects of adalimumab (HUMIRA, Abbott Laboratories, Abbott Park, IL, USA), a fully human, anti-tumor necrosis factor (anti-TNF) monoclonal antibody, on reducing fatigue in patients with RA. METHODS: A total of 1526 patients with RA were enrolled in 3 randomized, placebo-controlled clinical trials of adalimumab versus placebo plus methotrexate (MTX) or placebo plus standard antirheumatic therapies. Fatigue was assessed with the Functional Assessment of Chronic Illness Therapy (FACIT) fatigue scale questionnaire (which has been validated in RA) at baseline, mid-study, and at the end of the study. Logistic regression models were constructed using baseline demographic variables to test for treatment effect. In addition, sensitivity analyses were performed to determine the robustness of the data. RESULTS: At baseline in the 3 trials, patients' fatigue ranged from 27.9-29.7, representing considerable fatigue on the FACIT fatigue scale. Fatigue was significantly and consistently reduced in adalimumab-treated patients in the 3 clinical trials. Relative to placebo plus MTX, the adalimumab 40-mg-every-other-week dosage group reported statistically significantly less fatigue at all time points post-baseline. Improvements between adalimumab and placebo ranged from 3-7 points across all 3 trials, with a 3-4-point change representing a minimum clinically important difference. CONCLUSION: Adalimumab treatment was shown to significantly reduce fatigue in patients with moderate to severe RA. Changes in fatigue in all 3 trials were found to be clinically important. | |
19928400 | [Security of the combined treatment of methotrexate and leflunomide in patients with rheum | 2007 | Rheumatoid Arthritis (RA) is a chronic disease leading to functional impairment and early mortality. Treatment with disease-modifying antirheumatic drugs have shown to achieve disease remission and improves its evolution. The use of combined therapy should have a biological efficacy, no increased toxicity and have an acceptable dose interval. Also, it should begin its action quickly and be cost-effective. AIMS: to assess the security of the combined treatment with Methotrexate (MTX) and Leflunomide (LF) in patients with Rheumatoid Arthritis (RA) and to evaluate whether the dose and route of MTX administration influence on the toxicity. PATIENTS AND METHODS: Patients with RA who fulfilled ACR criteria and they attended to the Rheumatology Unit at Córdoba Hospital in the last 2 years were assessed. All the patients that received combined treatment with MTX in doses from 7.5 mg to 25 mg weekly orally (PO) or intramuscularly (i.m.) that started LF treatment in doses of 20 mg/day due to disease activity persistence were retrospectively assessed. Patients having at least 6 months of combined treatment were included. Data on treatment and adverse events were collected. They were evaluated at the beginning, at 6 and 12 months of treatment. The presence of adverse events as well as the stop of combined treatment was evaluated at 6 and 12 months of treatment. Adverse events in patients with oral and i.m. MTX treatment and in different doses were compared for the analyses. P<0.05 was considered significant. RESULTS: 62 patients with a mean age of 54 were included. 89% were female and had positive rheumatoid factor and 83% had radiological erosions. Eighty eight percent were in doses of 15 mg MTX, 4.9% with 10 mg and 25 mg at the beginning of LF treatment. Twenty four percent suffered from adverse events and 33% left the medication by 6 months. Among adverse events, 6 patients had diarrhea, 5 increased hepatic enzymes, 3 alopecia, 3 weight loss, and 2 had anemia and leucopenia. Eight patients stopped the medication in 6 months, but only 5 did because of adverse events. There was not significant statistical difference in adverse events between patients with different dose or routes of administration of MTX. CONCLUSIONS: The presence of adverse events in MTX and LF combined treatment was low and it developed during the first 6 months of treatment in our patients. The MTX route of administration and doses did not influence on the toxicity of the combined treatment with LF. The combined therapy seems to be a safe treatment option in RA patients. | |
18383539 | Golimumab in patients with active rheumatoid arthritis despite treatment with methotrexate | 2008 Apr | OBJECTIVE: To assess the efficacy, safety, and pharmacology of subcutaneous administration of golimumab in patients with active rheumatoid arthritis (RA) despite treatment with methotrexate (MTX). METHODS: Patients were randomly assigned in a double-blinded manner to receive injections of placebo plus MTX or 50 mg or 100 mg golimumab every 2 or 4 weeks plus MTX through week 48. Patients originally assigned to receive injections every 2 weeks had the interval increased to every 4 weeks starting at week 20. The primary end point was the proportion of patients meeting the American College of Rheumatology 20% improvement criteria (achieving an ACR20 response) at week 16. The study was powered to detect a difference in the primary end point when the combined golimumab groups and at least 1 of the individual dose groups were compared with placebo. RESULTS: The primary end point was attained. Sixty-one percent of patients in the combined golimumab plus MTX dose groups achieved an ACR20 response at week 16 compared with 37% of patients in the placebo plus MTX group (P=0.010). In addition, 79% of patients in the group receiving 100 mg golimumab every 2 weeks achieved an ACR20 response (P<0.001 versus placebo). Through week 20 (after which patients receiving placebo were switched to active infliximab therapy), serious adverse events were reported in 9% of patients in the combined golimumab groups and in 6% of patients in the placebo group. CONCLUSION: Golimumab plus MTX effectively reduces the signs and symptoms of RA and is generally well tolerated in patients with an inadequate response to MTX. | |
16636937 | Low-dose methotrexate-induced pancytopenia. | 2007 Jan | Methotrexate (MTX) has gained wide acceptance among both patients and rheumatologists due to its efficacy and safe therapeutic window in a variety of inflammatory rheumatological disorders. However, it has the potential to cause serious, life-threatening complications and even mortality. In the present series, we have reviewed our data of five patients who developed serious pancytopenia after the use of MTX, including one who died. Two of these resulted from prescription errors by primary care physicians. The clinical, laboratory, and outcome profile of all five cases are discussed with a brief review of the literature about MTX-induced pancytopenia. There is an urgent need to increase awareness in primary care physicians, patients, and pharmacists toward informed prescribing, dispensing, and monitoring of MTX to prevent such mishaps in the future. | |
17329305 | Adalimumab alone and in combination with disease-modifying antirheumatic drugs for the tre | 2007 Jun | OBJECTIVE: To evaluate the safety and effectiveness of adalimumab alone or in combination with standard disease-modifying antirheumatic drugs (DMARDs) for the treatment of rheumatoid arthritis (RA). METHODS: Patients with active RA despite treatment with DMARDs or prior treatment with a tumour necrosis factor antagonist participated in a multicentre, open-label clinical study of adalimumab 40 mg every other week for 12 weeks with an optional extension phase. Patients were allowed to continue with pre-existing traditional DMARDs. Long-term safety results are reported for all patients (4210 patient-years (PYs) of adalimumab exposure). The observed effectiveness results at week 12 are reported using American College of Rheumatology (ACR) and European League Against Rheumatism (EULAR) response criteria. RESULTS: Among the 6610 treated patients, adalimumab was generally well tolerated. Serious infections occurred in 3.1% of patients (5.5/100 PYs, including active tuberculosis, 0.5/100 PYs). Demyelinating disease (0.06%) and systemic lupus erythematosus (0.03%) were rare serious adverse events. The standardised incidence ratio of malignancy was 0.71 (95% CI 0.49 to 1.01). The standardised mortality ratio was 1.07 (95% CI 0.75 to 1.49). At week 12, 69% of patients achieved an ACR20 response, 83% a moderate, and 33% a good EULAR response. Adalimumab was effective in combination with a variety of DMARDs. The addition of adalimumab to antimalarials was comparably effective to the combination of adalimumab and methotrexate. CONCLUSIONS: Considering the limitations of an open-label study, adalimumab alone or in combination with standard DMARDs appeared to be well tolerated and effective in 6610 difficult-to-treat patients with active RA treated in clinical practice. |
