24584918 Vaccine responses in patients with rheumatoid arthritis treated with certolizumab pegol: r 2014 Apr OBJECTIVE: To evaluate the humoral immune response to pneumococcal and influenza vaccination in adults with rheumatoid arthritis (RA) receiving certolizumab pegol (CZP). METHODS: In this 6-week, single-blind, placebo-controlled trial with optional 6-month open-label extension (NCT00993668), patients were stratified by concomitant methotrexate (MTX) use and randomized to receive CZP 400 mg (loading dose; according to CZP label) or placebo at weeks 0, 2, and 4. Pneumococcal (polysaccharide 23) and influenza vaccines were administered at Week 2. Satisfactory humoral immune response, defined as ≥2-fold titer increase in ≥3 of 6 pneumococcal antigens and ≥4-fold titer increase in ≥2 of 3 influenza antigens, were assessed independently 4 weeks after vaccination. RESULTS: Following pneumococcal vaccination, 62.5% of placebo patients and 54.5% of CZP patients without effective titers at baseline achieved a humoral response (difference in proportions was -8.0 percentage points; 95% CI -22.5 to 6.6%). Following influenza vaccination, 61.4% of placebo and 53.5% of CZP patients without effective titers at baseline achieved a humoral response (difference in proportions: -8.0 percentage points; 95% CI -22.9 to 7.0%). In all patients, including those with effective titers at baseline, 58.2% of placebo and 53.3% of CZP patients developed satisfactory pneumococcal titers, and 54.1% of placebo and 50.5% of CZP patients developed satisfactory influenza antibody titers. Vaccine responses to pneumococcal and influenza antigens were reduced similarly in both treatment groups with concomitant MTX use. CONCLUSION: Humoral immune responses to pneumococcal and influenza vaccination are not impaired when given during the loading phase of CZP treatment in patients with RA. (ClinicalTrials.gov NCT00993668).
23505273 Disseminated Mycobacterium haemophilum infection in a 72-year-old patient with rheumatoid 2013 Mar 15 Mycobacterium haemophilum is a slow growing, aerobic, fastidious mycobacterium requiring hemin and a temperature of 30-32° C for optimal growth that is ubiquitous in nature. Disease in immunocompromised adults typically manifests as skin lesions such as papules, pustules and ulcerations. This organism also causes lymphadenitis in immunocompetent children. Antitumour necrosis factor-α (anti-TNF-α) therapy with agents such as infliximab, etanercept and adalimumab is increasingly being used for immunosuppression in patients with various autoimmune conditions. These agents are known to place patients at increased risk for tuberculosis and other granulomatous diseases. However, little is known about illness caused by M haemophilum in patients on immunosuppression with anti-TNF-α therapy. We describe a case of disseminated M haemophilum manifesting as skin lesions in a 72-year-old man with rheumatoid arthritis on infliximab and methotrexate.
23981406 Safety evaluation and therapeutic efficacy of Habb-e-Asgand, a commonly used antirheumatic 2013 Sep CONTEXT: Rheumatoid arthritis (RA) is a chronic autoimmune disorder. Habb-e-Asgand (HEA) is a polyherbal, Unani formulation widely used in the treatment of RA. Traditional systems of medicine or plant-based drugs are an attractive alternative treatment because of their professed efficacy in curing the disease. Medicinal herbs and herbal formulations are generally considered to be safer than the conventional drugs for RA. Unani drugs are known not to produce toxic effects and are presumed to be nontoxic. However, no objective, verifiable data exists to support the claims of nontoxicity and efficacy. OBJECTIVES: The present study was designed to evaluate the safety and therapeutic efficacy of HEA in Wistar rats. SETTING: The study took place at the University College of Medical Sciences and GTB Hospital, University of Delhi, Dilshad Garden, Delhi, India. DESIGN: Oral toxicity studies--one acute (14 d) and one long-term (90 d)--were carried out using three doses of HEA--57.5, 115, and 230 mg/kg body weight (BWT)--in both male and female rats. The research team also carried out a study on antirheumatic activity. The team induced arthritis in three groups of male rats using collagen type II (CII), and for 20 d, one group was treated once weekly with saline; a second group was treated once weekly with methotrexate (MTX) at 0.25 mg/kg BWT IP; and a third group was treated daily with HEA at 115 mg/kg BWT orally. A control group received saline but was not induced with RA. OUTCOME MEASURES: Rheumatoid factor (RF); anticyclic citrullinated peptide (a-CCP) antibody; antinuclear antibody (ANA); and C-reactive protein (CRP) were measured. RESULTS: The acute and long-term, oral toxicity studies showed that HEA administration did not produce any overt toxicity or mortality and that it was safe at all dose levels tested. No major alterations were observed in hematology, serum biochemistry, necropsy, and histopathology at the therapeutic equivalent dose (ie, 115 mg/kg BWT). HEA administration for 20 d in arthritis-induced rats significantly reduced the levels of autoantibodies and CRP, and the results were comparable with those of MTX, the standard, disease-modifying antirheumatic drug (DMARD). CONCLUSION: The study's results provided evidence that HEA is not toxic at the therapeutic dose. The antiarthritic activity of HEA may be due to its disease-modifying activities, thus supporting the traditional use of this formulation for treatment of RA.
23465067 Serum levels of lipoprotein(a) and E-selectin are reduced in rheumatoid arthritis patients 2013 May OBJECTIVES: To examine the effect of methotrexate (MTX) with or without tumor necrosis factor alpha (TNF-α)-inhibitors on serum lipoprotein(a) (s-Lp(a)), and to explore a possible relationship between s-Lp(a) and endothelial function (EF) in terms of serum levels of adhesion molecules and reactive hyperaemic index (RHI) in patients with rheumatoid arthritis (RA). METHODS: Serum levels of Lp(a), endothelial adhesion molecules, RHI and inflammatory markers were studied in 64 RA patients, starting with either MTX (n=34) or MTX+TNF-α-inhibitor treatment (n=30) at baseline and after 6 weeks and 6 months. RESULTS: Compared to baseline values, s-Lp(a) was significantly reduced after 6 weeks (p=0.001) and 6 months (p=0.001) in RA patients treated with MTX, and after 6 weeks (p=0.001) in the MTX+TNF-α-inhibitor group. A non-significant reduction was found after 6 months (p=0.102) in the MTX+TNFα-inhibitor group. Serum E-selectin (s-E-selectin) was significantly reduced in both RA treatment groups at both control points. S-Lp(a) correlated positively with s-E-selectin at baseline (p=0.004), and change in s-E-selectin correlated with the change in s-Lp(a) during follow-up (p6weeks= 0.008, p 6months=0.009). No association was found between s-Lp(a) and the other adhesion molecules and RHI. CONCLUSIONS: MTX or MTX combined with a TNFα-inhibitor appears to significantly reduce Lp(a). This finding indicate that s-Lp(a) might be related to systemic inflammation, or that the examined drugs might reduce s-Lp(a) by other mechanisms. Anti-inflammatory treatment might be a novel therapeutic option to decrease s-Lp(a). The associations between s-E-selectin and s-Lp(a) suggest an interaction between these factors, or a common cause.
24878863 Severe leukopenia in a rheumatoid arthritis patient treated with a methotrexate/leflunomid 2014 Mar A rheumatoid arthritis patient was treated for two years with methotrexate and leflunomide combination therapy. The evolution was uneventful until she had clopidogrel, simvastatin, isosorbide, aspirin and omeprazole added to medication due to acute myocardial infarction. Four weeks after this, she was hospitalized with severe leukopenia.
25401225 Hepatosplenic Hodgkin lymphoma without lymphadenopathy following reversible methotrexate-a 2017 Mar Lymphoproliferative disorders (LPDs) occur more frequently in rheumatoid arthritis (RA) patients treated with immunosuppressive agents than in the non-RA population. However, the various forms of disease progression have not yet been elucidated in detail. We encountered a case of Epstein-Barr virus (EBV)-positive atypical polymorphous LPD in the cervical and intraabdominal lymph nodes with hepatosplenomegaly in an 88-year-old female with RA who had taken infliximab and methotrexate (MTX) for six years. Although spontaneous remission occurred following the withdrawal of infliximab and MTX, reversible LPD evolved into hepatosplenic Hodgkin lymphoma without lymphadenopathy presenting as a cholestatic febrile illness. Our findings suggest that the recurrent lesions of MTX-associated LPDs may not always coincide with the primary lesion and may present unexplained findings based on various extranodal diseases.
25028370 Longterm retention rate and risk factor for discontinuation due to insufficient efficacy a 2014 Aug OBJECTIVE: Assessing retention rate and risk factor for drug discontinuation is important for drug evaluation. We examined a 3-year retention rate and the risk factor for discontinuation due to insufficient efficacy (IE) and adverse events (AE) in Japanese patients with rheumatoid arthritis (RA) who are receiving etanercept (ETN). METHODS: Data were collected from 588 patients treated with ETN as a first biologic from the Tsurumai Biologics Communication Registry. Baseline characteristics for the incidence of both IE and AE were analyzed using the Cox proportional-hazards regression model. Patients were divided into groups based on age and concomitant methotrexate (MTX). Drug retention rates were calculated using the Kaplan-Meier method and compared among groups using the log-rank test. RESULTS: ETN monotherapy without concomitant MTX [MTX(-)] was significantly related to a higher incidence of discontinuation due to IE [hazard ratio (HR) = 2.226, 95% CI 1.363-3.634]. Older age and MTX(-) were significantly related to a higher incidence of discontinuation due to AE [HR = 1.040, 1.746, 95% CI 1.020-1.060, 1.103-2.763, respectively]. The MTX(-)/≥ 65 years group had the lowest retention rate (p < 0.001). The discontinuation rate due to IE was lower in the MTX(+)/< 65 years group compared to < 65 years/MTX(-), ≥ 65 years/MTX(-) group (p = 0.006, p < 0.001, respectively). The discontinuation rate due to AE was highest in the MTX(-)/≥ 65 years group (p < 0.001). CONCLUSION: Our findings suggest that the risk of discontinuation due to IE was high in the patients who did not use concomitant MTX and that the risk of discontinuation due to AE was high in elderly patients who did not use concomitant MTX.
23311768 Effects of 12 months of treatment with disease-modifying anti-rheumatic drugs on low and h 2013 OBJECTIVES: Patients with rheumatoid arthritis (RA) have increased cardiovascular risk. The aim of the present study was the assessment of low density lipoprotein (LDL) and high density lipoprotein (HDL) subclass distribution in patients with early RA (ERA, n = 30) compared with age- and sex-matched healthy subjects (n = 30), as well the effect of treatment for 12 months with the disease-modifying anti-rheumatic drugs (DMARDs) methotrexate and prednisone in this distribution. METHOD: LDL and HDL subclass distribution was determined using a polyacrylamide gel-tube electrophoresis method. RESULTS: ERA patients exhibited increased levels of inflammatory markers and high disease activity score. ERA patients had higher serum levels of total cholesterol (TC), LDL cholesterol (LDL-C), and triglycerides (TG) whereas their serum HDL cholesterol (HDL-C) levels were significantly lower compared with controls. ERA patients exhibited significantly higher plasma levels of small dense LDL-C (sdLDL-C), leading to a significantly decreased mean LDL diameter. ERA patients had significantly decreased small HDL particles (HDL-3) concentration whereas serum levels of large HDL particles (HDL-2) did not differ compared with controls. Treatment with DMARDs resulted in a significant decrease in inflammatory markers and disease activity, along with a significant increase in HDL-C serum levels. The concentration of sdLDL-C did not change significantly during treatment. We observed a significant increase in the levels of large HDL-2 whereas the concentration of small HDL-3 did not significantly change. CONCLUSIONS: Patients with ERA have increased sdLDL-C levels and decreased HDL-C levels because of decreased concentration of the small HDL-3 subclass. The administration of DMARDs induced a significant increase in HDL-C levels, which was attributed to the increase in large HDL-2 serum concentration.
24927637 Methotrexate-associated lymphoproliferative disorders of the tongue developing in patients 2015 Jan Incidences of lymphoproliferative disorders (LPDs) in patients with compromised immune systems associated with immunosuppressants such as methotrexate (MTX) administered for the treatment of rheumatoid arthritis (RA) are reportedly increasing. Although extranodal lesions develop in half of the patients with MTX-associated LPDs, only a few studies have reported on intraoral lesions. We evaluated 2 elderly women with MTX-associated LPDs who had received MTX for the treatment of RA and presented with atypical ulceration of the tongue. Biopsy specimens demonstrated polymorphous B-cell LPD, probably associated with MTX. Epstein-Barr virus (EBV) was identified by immunohistochemistry for latent membrane protein 1 and by EBV-encoded RNA in situ hybridization. After MTX withdrawal, in both cases, ulcers showed complete regression at 8 weeks, and no subsequent treatment was required. Close monitoring of LPDs is mandatory, because recurrence within 10 months has been reported in half of the patients in whom LPDs had initially regressed.
25480531 [Intra-articular injections of triamcinolone hexacetonide in rheumatoid arthritis: short a 2015 May OBJECTIVES: Identify good response predictors to intra-articular injection (IAI) with triamcinolone hexacetonide (TH). METHODS: This study was carried out in rheumatoid arthritis (RA) patients (American College of Rheumatology criteria) submitted to IAI (mono, pauci or polyarticular injection). ASSESSMENT: A "blinded" observer prospectively evaluated joints at one week (T1), four weeks (T4), twelve weeks (T12) and 24 weeks (T24) after IAI. Outcome measurements included Visual Analogue Scale (0-10 cm) at rest, in movement and for swollen joints. Clinical, demographic and variables related to injection at baseline were analyzed according to IAI response. RESULTS: We studied 289 patients with RA (635 joints) with a mean age of 48.7 years (±10.68), 48.5% of them Caucasians, VAS for global pain=6.52 (±1.73). Under univariate analysis, the variables relating the best responses following IAI (improvement > 70%) were: "elbow and metacarpophalangeal (MCP) IAI, and functional class II". Under multivariate analysis, "males" and "non-whites" were the predictors with the best response to IAI at T4, while "elbow and MCP IAI", "polyarticular injection", "use of methotrexate" and "higher total dose of TH" obtained the best response at T24. CONCLUSION: Several predictors of good response to IAI in patients with RA were identified. The best-response predictors for TH IAI of long term were "apply elbow and MCP IAI" and "apply polyarticular injection".
24619653 Induction therapy with combination TNF inhibitor and methotrexate in early rheumatoid arth 2014 May With the introduction of more objective disease activity measures and the development of biological therapies, there were dramatic changes in the treatment of rheumatoid arthritis (RA). The combination therapy with tumor necrosis factor (TNF) inhibitor and methotrexate (MTX) has unprecedentedly improved prognosis and outcomes, and very low disease activity or remission has been achievable goal in RA. Although the concept of remission induction and maintenance was first discussed in longstanding RA patients, several clinical trials have demonstrated that there is a therapeutic window of opportunity, and early effective control of inflammation in early RA could lead to less joint damage and better long-term outcomes. Emerging evidence suggests that early combination therapy with TNF inhibitor and MTX leads to rapid clinical remission and thereby improved quality of life. Furthermore, remission status may be sustained in some patients even if a TNF inhibitor is discontinued after sustained remission in early RA patients. While there are many potential benefits of early remission induction therapy with the combination of a TNF inhibitor and MTX, the best therapeutic regimen and strategy for remission induction and maintenance in early RA remain controversial. There are no data to decide a priori when and in whom TNF blocker drugs are indicated in early disease-modifying anti-rheumatic drug (DMARD)-naïve RA.
24285764 Tofacitinib: The First Janus Kinase (JAK) inhibitor for the treatment of rheumatoid arthri 2013 Nov OBJECTIVE: To review the pharmacology, pharmacokinetics, efficacy and safety, dosage administration, and adverse effects of tofacitinib for rheumatoid arthritis (RA) treatment. DATA SOURCES: Primary sources of information were obtained from clinical studies, which were identified through PubMed (1966 to June 2013) and International Pharmaceutical Abstracts (1970 to March 2013) using terms: tofacitinib, tasocitinib, CP-690550, and CP-690,550. Information was used from tofacitinib package insert, guidelines, and published abstracts from the American College of Rheumatology (ACR) and the European League Against Rheumatism. STUDY SELECTION AND DATA EXTRACTION: Data search was limited to include publications in English language and from human subjects. DATA SYNTHESIS: Tofacitinib is the first oral Janus kinase inhibitor indicated for treatment of moderate to severe RA. Tofacitinib demonstrated efficacy and safety comparable to other disease-modifying antirheumatic drugs (DMARDs). Tofacitinib was efficacious in RA patients, indicated by achievements of ACR20, ACR50, and ACR70 criteria. Similar improvements were observed in patients who met remission criteria based on the Disease Activity Scores 28 criteria and quality of life as measured by the Health Assessment Questionnaire-Disability Index (HAQ-DI). Tofacitinib was associated with infections and malignancies; and elevations in serum creatinine and lipids were observed. Drug interactions with inducers and inhibitors of the cytochrome P-450 3A4 and 2C9 isoenzymes were reported. CONCLUSIONS: Tofacitinib is an oral treatment option for RA patients who have inadequate response or intolerance to methotrexate. Postmarket surveillance will provide further insight to tofacitinib's role in RA therapy, especially in patients who may require different types of combination therapy with DMARDS.
22752502 The time course of gastric methotrexate intolerance in patients with rheumatoid arthritis 2013 May OBJECTIVES: This study aimed to evaluate the incidence and the time course of methotrexate (MTX)-associated gastric intolerance in patients with rheumatoid arthritis and psoriatic arthritis. METHODS: Four hundred twenty subjects undergoing MTX treatment for rheumatoid arthritis (n = 346) and psoriatic arthritis (n = 74) were retrospectively assessed. The incidence and time course of gastric MTX intolerance resulting in treatment discontinuation were investigated. In addition, the relations between gastric intolerance and patient characteristics, including gender, age, diagnosis, and rheumatoid factor (RF) positivity, were examined. RESULTS: Overall, oral MTX discontinuation rate due to gastric intolerance was 28.6 %. The time to discontinuation for oral MTX was 8.1 ± 11.5 months on average, with more than half of the discontinuations occurring within the first three months of treatment. Discontinuation was not associated with gender, age, diagnosis, or RF positivity. More than half of the patients that switched to a parenteral treatment regimen (52.6 %, 20/38) could tolerate the agent. CONCLUSIONS: Gastric MTX intolerance usually develops within the first year of treatment and presents a major obstacle to long-term treatment retention in patients with rheumatologic disease. However, parenteral MTX appears to be a good alternative for patients intolerant of oral MTX.
24881737 Deterioration of the immune response induced by sulfamethoxazole-trimethoprim in a rheumat 2014 A 73-year-old woman with rheumatoid arthritis treated with methotrexate and prednisolone was admitted with dyspnea and ground-glass opacity on chest CT. We diagnosed her with Pneumocystis jirovecii pneumonia (PCP) based on a positive PCR analysis of Pneumocystis jirovecii and the presence of cysts in bronchoalveolar lavage fluid. The PaO2 was 74.7 Torr on room air, and treatment with sulfamethoxazole-trimethoprim only was initiated. The hypoxemia and ground-glass opacity increased on hospital day 3, and the administration of adjunctive steroid therapy resulted in an improvement in the patient's condition. Although patients with PCP with HIV infection and hypoxemia are often treated with adjunctive steroid therapy to prevent adverse immune reactions, the efficacy of additive steroid administration in case of non-HIV PCP has not been established.
23980529 Upregulated baseline plasma CCL19 and CCR7 cell-surface expression on monocytes in early r 2014 OBJECTIVES: The aim of this study was to measure, in early rheumatoid arthritis (RA) patients, the concentration of CC-chemokine ligand 19 (CCL19) in plasma and the cell-surface expression of CC-chemokine receptor 7 (CCR7) on circulating monocytes and CD4+ T lymphocytes and to analyse correlations with disease activity and 5-year radiographic progression. METHOD: In disease-modifying anti-rheumatic drug (DMARD)-naïve RA patients (disease duration < 6 months), we measured plasma CCL19 by enzyme-linked immunosorbent assay (ELISA) (n = 160) and CCR7 cell-surface expression on monocytes and CD4+ T lymphocytes by flow cytometry (n = 40) at baseline and after 1 year of treatment with methotrexate (MTX) or methotrexate+cyclosporin A (MTX/CyA). Radiographic progression was scored by the van der Heijde-modified Total Sharp Score (TSS) from 0 to 5 years. RESULTS: Increased baseline CCL19 (median 85 pg/mL, range 31-1008 pg/mL, p = 0.01) decreased after 1 year (median 31 pg/mL, range 31-1030 pg/mL, p < 0.001) and 5 years (median 31 pg/mL, range 31-247 pg/mL, p < 0.001) to a level below the controls (n = 45) (median 60 pg/mL, range 31-152 pg/mL). Baseline plasma CCL19 levels [p = 0.011, 95% confidence interval (CI) 0.0030-0.0176], anti-cyclic citrullinated peptide (anti-CCP) antibody status (p = 0.002, 95% CI 0.61-2.38), and TSS > 0 at baseline (p < 0.001, 95% CI 1.21-3.16) were independent predictors of 5-year radiographic progression evaluated by multiple logistic regression in contrast to never smoked, C-reactive protein (CRP), gender, age, number of tender (NTJ) and swollen joints (NSJ), and 28-joint Disease Activity Score (DAS28). Increased CCR7 expression on monocytes (p = 0.008) correlated to CRP (p = 0.006, r = 0.52) and normalized (n = 15) after 1 year (p = 0.02). CONCLUSIONS: In DMARD-naïve RA patients, CCL19 plasma level and CCR7 surface expression on monocytes were upregulated and normalized after 1 year of treatment. Increased baseline plasma CCL19 level, anti-CCP antibody status, and TSS > 0 at baseline correlated independently with 5-year radiographic progression.
23982537 Comparative efficacy of subcutaneous versus oral methotrexate in active rheumatoid arthrit 2013 Jul This prospective study was conducted in rheumatology clinic under the department of medicine of Bangabandhu Sheikh Mujib Medical University from December 2004 to December 2005 to asses the efficacy, safety and compliance of subcutaneous methotrexate (MTX) in active rheumatoid arthritis (RA) patients. A total of 92 active rheumatoid arthritis patients according to American College of Rheumatology (ACR) criteria were recruited for the trial for six months. Among them 46 cases belonged to injectable MTX group and 46 cases belonged to oral MTX group. Mean±SD age of patients was 45.54±12.42 vs. 44.63±13.99 years in subcutaneous group and oral group respectively. In the subcutaneous group 41 were female and 5 male; in the oral group 34 were female and 12 male. Mean duration of the disease was 49.74 months in subcutaneous group and 49 months in oral group. RA test was positive in 35 cases in both groups whereas Rose Waaler test was positive in 19 patients in subcutaneous group and 14 patients in oral group. At 24 week, response rate of ACR 20 was significantly higher in subcutaneous MTX than oral MTX group (93% vs. 80%, p=0.02). Similarly ACR 50 response was significantly higher in subcutaneous MTX than in oral group (89% vs. 72%, p=0.03). ACR 70 response was not significantly higher in SCMTX group then oral group (11% vs. 9 %, p=0.72). Adverse effects were relatively less in subcutaneous MTX and most common side effects were nausea (37% vs. 63%), vomiting (11% vs. 30%), dyspepsia (29% vs. 48%), dizziness (4l% vs. 52%) and alopecia (72% vs. 85%). The results of the study demonstrated that subcutaneous MTX was significantly more effective than oral MTX at the same dosage in active Rheumatoid arthritis patients with no increase in side effects.
23686414 Validation of the methotrexate-first strategy in patients with early, poor-prognosis rheum 2013 Aug OBJECTIVE: Methotrexate (MTX) taken as monotherapy is recommended as the initial disease-modifying antirheumatic drug for rheumatoid arthritis (RA). The purpose of this study was to examine outcomes of a blinded trial of initial MTX monotherapy with the option to step-up to combination therapy as compared to immediate combination therapy in patients with early, poor-prognosis RA. METHODS: In the Treatment of Early Rheumatoid Arthritis (TEAR) trial, 755 participants with early, poor-prognosis RA were randomized to receive MTX monotherapy or combination therapy (MTX plus etanercept or MTX plus sulfasalazine plus hydroxychloroquine). Participants randomized to receive MTX monotherapy stepped-up to combination therapy at 24 weeks if the Disease Activity Score in 28 joints using the erythrocyte sedimentation rate (DAS28-ESR) was ≥3.2. RESULTS: Attrition at 24 weeks was similar in the MTX monotherapy and combination groups. Of the 370 evaluable participants in the initial MTX group, 28% achieved low levels of disease activity and did not step-up to combination therapy (MTX monotherapy group). The mean ± SD DAS28-ESR in participants continuing to take MTX monotherapy at week 102 was 2.7 ± 1.2, which is similar to that in participants who were randomized to immediate combination therapy (2.9 ± 1.2). Participants who received MTX monotherapy had less radiographic progression at week 102 as compared to those who received immediate combination therapy (mean ± SD change in modified Sharp score 0.2 ± 1.1 versus 1.1 ± 6.4). Participants assigned to initial MTX who required step-up to combination therapy at 24 weeks (72%) demonstrated similar DAS28-ESR values (3.5 ± 1.3 versus 3.2 ± 1.3 at week 48) and radiographic progression (change in modified Sharp score 1.2 ± 4.1 versus 1.1 ± 6.4 at week 102) as those assigned to immediate combination therapy. The results for either of the immediate combination approaches, whether triple therapy or MTX plus etanercept, were similar. CONCLUSION: These results in patients with early, poor prognosis RA validate the strategy of starting with MTX monotherapy. This study is the first to demonstrate in a blinded trial that initial MTX monotherapy with the option to step-up to combination therapy results in similar outcomes to immediate combination therapy. Approximately 30% of patients will not need combination therapy, and the 70% who will need it are clinically and radiographically indistinguishable from those who were randomized to receive immediate combination therapy.
25054600 Rituximab for rheumatoid arthrits treatment: a systematic review. 2014 May INTRODUCTION: Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by systemic joint inflammation that often leads to significant disability. Several effective anti-TNF agents have been used, but some patients have shown an inadequate response. Rituximab is a therapeutic monoclonal antibody indicated in such cases. METHODS: We conducted a systematic review to access efficacy and safety of rituximab in patients with active RA which have or have not been treated with anti-TNF agents before, and to relate outcome with RF and anti-CCP serology. We searched major electronics databases, grey literature and searched for references manually. We used Review Manager(r)5.1 for meta-analysis. RESULTS: We included six RCTs comparing rituximab 1000 mg with placebo. Methotrexate was used by both groups. Treatment with rituximab was more effective in naïve and in anti-TNF treatment failure patients - ACR20/50/70 and EULAR response. We observed lower changes in Total Genant-modified Sharp score, erosion score and joint narrowing scores in the rituximab group, and SF-36, FACIT-T and HAQ-DI scores were also better in this group. There were no differences between groups regarding safety outcomes, with exception of acute injection reactions, which were more common on rituximab group. More RF/anti-CCP seropositive patients achieved ACR20 than RF/anti-CP negative patients in rituximab group. CONCLUSION: Available data support the use of rituximab for the treatment of RA, as it is an effective and safe option for naïve and anti-TNF treatment failure patients. RF and anti-CCP seam to influence treatment results, but this inference needs further research.
23908006 Induced abortions in women with rheumatoid arthritis receiving methotrexate. 2013 Aug OBJECTIVE: To determine the rate of induced abortions in women with rheumatoid arthritis (RA) exposed to methotrexate (MTX) compared with women with RA unexposed to this medication. METHODS: We performed a nested case-control study using administrative databases from Quebec. All women with RA ages 15-45 years were identified and cases were defined as women having an induced abortion. Each case was matched to ≥1 controls for age, calendar time, and cohort entry. Exposure was defined as having filled ≥1 prescriptions of MTX ≤16 weeks prior to the index date. RESULTS: We identified 112 cases of induced abortions in women with RA and 5,855 RA controls. Exposure to MTX occurred in 10.7% of cases and 21.7% of controls. Women exposed to MTX had a lower rate of induced abortions compared with unexposed women (rate ratio [RR] 0.47 [95% confidence interval (95% CI) 0.25-0.89]). In the multivariate analysis, there was a trend toward an increased rate of induced abortions among women exposed to anti-tumor necrosis factor (anti-TNF) agents (RR 2.07 [95% CI 0.81-5.27]). CONCLUSION: Women with RA exposed to MTX have a lower rate of induced abortions than unexposed women. Women with RA exposed to anti-TNF agents may have an increased rate of induced abortions compared to unexposed women.
25359291 Soluble OX40L is associated with presence of autoantibodies in early rheumatoid arthritis. 2014 Oct 30 INTRODUCTION: OX40 and its ligand OX40L are key components in the generation of adaptive memory response and provide necessary co-stimulatory signals for activated effector T cells. Here we investigate the dual roles of the membrane and soluble (s) forms of OX40 and OX40L in plasma and synovial fluid and their association with autoantibodies and disease activity in rheumatoid arthritis (RA). METHODS: Soluble OX40 and sOX40L plasma levels were measured in treatment-naïve early RA patients (eRA) at baseline and after 3, 6, and 12 months of treatment with methotrexate and adalimumab (n = 39) and with methotrexate alone (n = 37). Adalimumab was discontinued after the first year, and patients were followed for additional 12 months. For comparison, sOX40 and sOX40L were measured in patients with chronic RA (cRA, n = 15) and healthy volunteers (HV, n = 34). Membrane-bound OX40 and OX40L expression on T cells, B cells and monocytes were quantified. RESULTS: Soluble OX40 plasma levels of eRA patients were not different at the time of treatment initiation, but were significantly higher after 12 months of treatment, compared with HV or cRA patients. Soluble OX40L was significantly elevated throughout the first 12 months of treatment compared with HVs and patients with cRA. Adalimumab treatment did not influence sOX40 or sOX40L plasma levels. At baseline, sOX40L levels were strongly associated with the presence of anti-citrullinated protein antibodies (ACPA) (P <0.001) and IgM-RF (P <0.0001). The sOX40/sOX40L ratio was decreased in eRA, and a low ratio at the time of adalimumab discontinuation was associated with increased DAS28CRP and risk of flare the following year. T cells in the synovial fluid had the highest expression of OX40, while monocytes and B cells were the main expressers of OX40L in the joint. CONCLUSIONS: Plasma levels of sOX40 and sOX40L were increased in eRA and sOX40L was correlated with ACPA and IgM-RF. Further, expression of membrane-bound OX40 and OX40L was increased in eRA and cRA. Combined, these findings could reflect that increased activity in the OX40 systems facilitate to drive disease activity and autoantibody production in RA.
