27175296 Relationship between clinical and patient-reported outcomes in a phase 3 trial of tofaciti 2016 OBJECTIVE: To compare the relationship between clinical measures and patient-reported outcomes (PROs) in patients with rheumatoid arthritis (RA) treated with tofacitinib or methotrexate (MTX). METHODS: In a phase 3 randomised controlled trial, patients (N=956) who were MTX-naïve or had received ≤3 doses were randomised and received tofacitinib 5 or 10 mg twice daily or MTX titrated to 20 mg/week. Outcomes included: per cent of patients achieving American College of Rheumatology 70% responses (ACR70), ACR50, low disease activity (LDA) by Simplified Disease Activity Index (SDAI ≤11) and Clinical Disease Activity Index (CDAI ≤10), remission by SDAI (≤3.3) and CDAI (≤2.8), patient-reported Health Assessment Questionnaire-Disability Index (HAQ-DI scores <0.5), pain and global assessment of disease activity. RESULTS: At month 6, most patients who achieved LDA/remission by one definition achieved LDA/remission with others; however, discordance between measures was greater with MTX than with tofacitinib. As expected, concordance between CDAI and SDAI responses was high. Overall, patients achieving LDA or ACR50 responses reported less improvement in PROs (HAQ-DI, pain and patient global assessment) compared with clinical measures (tender and swollen joint counts). CONCLUSIONS: Variability in levels of responses between clinical outcomes and PROs should be considered when setting treat-to-target goals in patients with RA. TRIAL REGISTRATION NUMBER: NCT01039688; Post-results.
27747531 Rituximab for Rheumatoid Arthritis. 2015 Dec Rituximab is a chimeric monoclonal antibody directed at the CD20 molecule on the surfaces of some but not all B cells. It depletes almost all peripheral B cells, but other niches of B cells are variably depleted, including synovium. Its mechanism of action in rheumatoid arthritis (RA) is only partially understood. Rituximab was efficacious in clinical trials of patients with RA, including those who are methotrexate naïve, those with an incomplete response to methotrexate, and those with an incomplete response to tumor necrosis factor inhibitors. The need for a concomitant traditional disease-modifying drug, the optimal dose of rituximab, and the optimal interval for retreatment remain somewhat uncertain. Rituximab seems to be most efficacious in seropositive patients and those with an incomplete response to only one tumor necrosis factor inhibitor. Rituximab has a reasonable safety profile, with a small risk of serious infectious events, which is stable over time and repeat courses. Opportunistic infections are rare. Reactivation of hepatitis B remains a concern. The possible association of rituximab and progressive multifocal leukoencephalopathy may still require vigilance. Malignancies and cardiovascular events do not appear to be increased. Infusion reactions are more likely with the initial infusion, and are usually mild. Rituximab may cause hypogammaglobulinemia, but any risk of subsequent risk of increased infectious events is not yet well established. Before initiating rituximab, patient screening for hypersensitivity to murine proteins, infections, congestive heart failure, pregnancy, and hypogammaglobulinemia is imperative. Vaccinations should be administered prior to treatment whenever possible. Rituximab has been a significant addition to the rheumatologists' armamentarium for the treatment of RA.
27182251 Adherence to Methotrexate therapy in Rheumatoid Arthritis. 2016 Mar OBJECTIVE: To determine adherence to methotrexate (MTX) therapy in patients with Rheumatoid Arthritis (RA) and to identify factors that promote either adherence or non adherence. METHODS: One hundred Rheumatoid Arthritis patients on MTX for at least two months were enrolled. Questionnaire was completed by direct interview. Details recorded were, demographics (age, sex, education, monthly income), disease duration, duration on MTX and current dose. Disease Activity Score on 28 joint counts (DAS 28) at the current visit, concomitant drugs taken and number of doses of MTX missed in the previous 8 weeks were noted. Non adherence was defined as omission of any three or more prescribed doses of MTX in previous 8 week. Patients were asked for the factors that motivated their adherence to MTX as well as factors for non adherence. Presence of side effects due to MTX was also recorded. RESULT: Non adherence was found among 23% of cases. Patients of low socioeconomic group (p <0.0001) and on MTX for longer duration (p <0.001) had higher non adherence. Non adherent patients had significantly higher disease activity as measured by DAS 28 (p<0.001). Good counseling and education by the doctor was a strong predictor of adherence (p <0.001). Lack of affordability (p <0.001); lack of availability at local pharmacy (p <0.001); lack of family support (p <0.001) and lack of awareness regarding need and importance of MTX (p < 0.001were found as significant factors for non adherence. CONCLUSION: MTX non adherence in RA is noted in about one fourth of study group. Various economical and social issues lead to non adherence but good patient education and counseling by doctor could promote adherence in this study group.
27175292 Efficacy of etanercept in combination with methotrexate in moderate-to-severe rheumatoid a 2016 OBJECTIVE: To evaluate the impact of methotrexate (MTX) dosage on clinical, functional and quality of life outcomes in patients with rheumatoid arthritis (RA) from two previous etanercept (ETN) trials after 24 months of treatment. METHODS: Patients with active RA in the ETN+MTX combination treatment arms of the Trial of Etanercept and Methotrexate with Radiographic Patient Outcomes (TEMPO) and COmbination of Methotrexate and ETanercept in Active Early Rheumatoid Arthritis (COMET) studies were pooled in this post hoc analysis and stratified by MTX dosage at 24 months, having MTX monotherapy groups as control: low dose, <10.0 mg/week; medium dose, 10.0-17.5 mg/week; and high dose, >17.5 mg/week. Data from these patient subgroups were included in descriptive summaries of demographic and disease characteristics at baseline. The following outcomes at 24 months were also evaluated for each subgroup: Disease Activity Score in 28 joints (DAS28) low disease activity (LDA) and remission; American College of Rheumatology 20%, 50% and 70% improvement criteria (ACR20, 50 and 70) responses; and changes from baseline in DAS28, Health Assessment Questionnaire Disease Index (HAQ-DI) and EuroQol 5-dimensions visual analogue scale (EQ-5D VAS). RESULTS: Baseline demographics were similar between the low, medium and high MTX dose groups in the ETN+MTX combination and MTX monotherapy arms, with the exception of disease duration (ETN+MTX low 5.5; medium 5.1; high 0.8 years vs MTX low 8.3; medium 4.7; high 0.8 years). Responses to ETN+MTX combination therapy at 24 months were consistently high across MTX dosage groups, with very similar rates of DAS28 LDA/remission and ACR20/50/70. Improvements in DAS28, HAQ-DI and EQ-5D VAS were also not dependent on MTX dosage in the combination treatment arm. CONCLUSIONS: Patients with RA in the TEMPO and COMET trials who received ETN+MTX showed similar efficacy outcomes at 24 months, regardless of MTX dosage. TRIAL REGISTRATION NUMBERS: NCT00195494 (COMET) and NCT00393471 (TEMPO).
26981298 A Woman with Rheumatoid Arthritis and a Bilateral Fracture of the Proximal Tibia. 2016 A 52-year-old woman presented herself with pain on the medial sides of the proximal tibia after a minimal trauma. Conventional X-rays did not show any pathology. However, the MRI showed a bilateral fracture of the proximal tibia. Since the patient was treated with methotrexate due to rheumatoid arthritis, methotrexate osteopathy was considered. Long term treatment with low doses of methotrexate proved to inhibit osteoblast proliferation and may eventually lead to decreased bone formation and osteopenia. On the other hand, immobilization, joint deformities, and steroid treatment are associated with rheumatoid arthritis and are also known risk factors for fractures. The clinical relevance of methotrexate osteopathy still has to be established. However, if a patient treated with methotrexate localizes pain in the tibia, methotrexate osteopathy should be considered. Withdrawal of the drug may improve symptoms.
27073419 Management of rheumatoid arthritis: Impact and risks of various therapeutic approaches. 2016 Apr Rheumatic diseases are highly prevalent chronic disorders and the leading cause of physical disability worldwide, with a marked socio-economic impact. Rheumatoid arthritis (RA) is a chronic systemic inflammatory disease of unknown etiology with an autoimmune pathogenesis, characterised by arthropathy with chronic, deforming, destructive evolution and multiple systemic manifestations. The management of RA has undergone significant changes as far as objectives and approaches are concerned, ending in the current strategy known as 'treat to target'. The therapeutic array of RA includes several categories of medicinal products, of varying potential. There are several criteria for the classification of medicinal products used against this disease, one of the most important and modern of which divides such substances according to their effects on the progress of the disease: symptom-modifying antirheumatic drugs (including non-steroidal anti-inflammatory drugs and corticoids), disease-modifying antirheumatic drugs (including various substances, such as gold salts, antimalarials, sulfasalazine, D-penicillamine; non-specific immunosuppressive medication, such as methotrexate, cyclophosphamide, azathioprine and leflunomide) and biological therapy is a recent addition, providing new insight into the treatment of this disease. The selection of the optimal therapy for RA should be based on guidelines and recommendations, but also on clinical particular aspects and patient preferences.
25694859 Drug free remission after steroid-dependent disappearance of lymphoproliferative disorder 2015 INTRODUCTION: TNF-α inhibitors plus MTX appear to have benefit in the longer-term reduction of RA. Boolean long-term remission under drug-free conditions is rare. The therapeutic mechanism and the factor of predicting response have not been clarified yet. CASE DESCRIPTION: A 24-year-old female rheumatoid arthritis (RA) patient, who once attained complete remission (CR) with the combination therapy with tumor necrosis factor alpha (TNF-alpha) inhibitor adalimumab (ADA) and methotrexate (MTX), showed the occurrence of Epstain- Barr virus (EBV)-associated lymphoproliferative disorder (LPD). Pulse treatment with methylprednisolone after the termination of anti TNF-α therapy resulted in the remission of EBV-associated LPD. The administration of prednisolone (PSL) was tapered off after the improvement of clinical symptoms and laboratory data. The patients achieved drug-free 12 months after urgent hospitalization and delivered healthy baby 2 years after hospital discharge. She has been complete drug-free Boolean remission for 5 years. DISCUSSION AND EVALUATION: The purpose of this brief case is report that we experienced the remission of LPD after CR with combined therapy with ADA and MTX. We believe this case report will be one of the paths for unveiling the pathogenesis and improving the treatment for RA. CONCLUSIONS: We believe this case report will be one of the paths for unveiling the pathogenesis and improving the treatment for RA.
26059273 Methods for treating IL-6-related diseases (US2015010554A1): a patent evaluation. 2015 INTRODUCTION: IL-6 is involved in a variety of diseases such as acute or chronic inflammation and autoimmune diseases, and the modulation of IL-6 level is recognized as an important target. Therefore, the blocking agent of IL-6 receptor (IL-6R), particularly anti-IL-6R antibody, was invented and its clinical efficacy was well resolved. However, it has not been shown that synergistic effects can be achieved by the combination of anti-IL-6R antibody with immunosuppressants. AREAS COVERED: This patent assessed the possible use of anti-IL-6R antibody (tocilizumab) plus methotrexate (MTX) for the treatment of acute or chronic inflammatory diseases and autoimmune diseases including nephritis, Crohn's disease, ulcerative colitis, pancreatitis, juvenile idiopathic arthritis, rheumatoid arthritis, and psoriasis. A large Phase II trial of tocilizumab to determine the optimum dose of tocilizumab alone and in combination with MTX for the treatment of rheumatoid arthritis was carried out and its result was analyzed. In conclusion, the combination use of tocilizumab plus MTX was confirmed as clinically effective and safe for the treatment of rheumatoid arthritis whereas substantial evidence regarding superiority to tocilizumab monotherapy is still lacking. EXPERT OPINION: To prove synergistic effect or enhancement of tocilizumab plus MTX therapy, more diverse diseases related to IL-6 and tocilizumab therapy, not limited to rheumatoid arthritis, have to be evaluated, along with its safety.
26309500 Meridian-sinew release therapy for the treatment of refractory rheumatoid arthritis. 2015 OBJECTIVE: To evaluate the efficacy and safety of Meridian-sinew Release therapy in Chinese patients with refractory active Rheumatoid Arthritis (RA). SUMMARY OF BACKGROUND DATA: Few studies focused on the effect of combination of Meridian-sinew Release therapy and Methotrexate (MTX) on refractory active RA of Chinese patients. METHODS: Eighty refractory active rheumatoid arthritis patients were randomized to receive Meridian-sinew Release+MTX 10 mg (n=40), MTX 10 mg (n=40) every week for 12 weeks. The primary end point was the proportion of patients achieving ≥20% improvement in the American College of Rheumatology criteria (ACR20) at week 12. Secondary efficacy endpoints included 28-joint disease activity score with ESR (DAS28-ESR), simplified disease activity index (SDAI), clinical disease activity index (CDAI) and Health Assessment Questionnaire-Disability Index (HAQ-DI). RESULTS: Week 12 ACR20 response rates were significantly greater in Meridian-sinew Release+MTX group (30/38 (78.9%)) than in MTX group (19/37 (51.3%)), (P<0.001), as were ACR50 and ACR70 response rates. Patients treated with Meridian-sinew Release+MTX were significantly more likely to achieve clinical remission, using various definitions, at 12 weeks versus MTX alone. A larger percentage of Meridian-sinew+MTX patients than MTX alone patients were in states of low disease activity or remission for DAS28-ESR, SDAI and CDAI after 12 weeks of treatment. CONCLUSION: Our study suggests that Meridian-sinew Release therapy was well tolerated and efficacious in improving clinical outcomes in Chinese patients with refractory active RA.
27160252 APL-1, an altered peptide ligand derived from heat-shock protein, alone or combined with m 2017 May Induction of tolerance to autoantigens in vivo is a complex process that involves several mechanisms such as the induction of regulatory T cells and changes in the cytokine and chemokine profiles. This approach represents an attractive alternative for treatment of autoimmune diseases. APL-1 is an altered peptide ligand derived from a novel CD4 + T cell epitope of human heat-shock protein of 60 kDa (HSP60), an autoantigen involved in the pathogenesis of rheumatoid arthritis (RA). We have shown previously that this peptide efficiently inhibited the course of adjuvant-induced arthritis in Lewis rats and induced regulatory T cell (Treg) in ex vivo assay with PBMC isolated from RA patients. This study was undertaken to evaluate the therapeutic effect of APL-1 and its combination with methotrexate (MTX) in collagen-induced arthritis (CIA). CIA was induced in male DBA/1 mice at 8 weeks of age by immunization with chicken collagen. APL, MTX or both were administrated beginning from arthritis onset. Therapeutic effect was evaluated by arthritis and joint pathologic scores. In addition, TNFα and IL-10 in sera were measured by ELISA. Treg induction was assessed by FACS analysis. APL-1 inhibits efficiently the course of arthritis in CIA, similar to MTX. In addition, therapy with APL-1 plus MTX reduced CIA in mice, associated with an increase in Treg. These facts reinforce the therapeutic possibilities of APL-1 as a candidate drug for treatment of RA.
25868948 Radiological improvement by tocilizumab in polyarticular juvenile idiopathic arthritis. 2015 Apr Recent advances in biologic therapy have enabled reduction of the progression of destructive arthritis in rheumatoid arthritis. Once destroyed, however, the affected bones and cartilage are not fully repaired. We describe the case of an 8-year-old girl with anti-citrullinated peptide antibody (ACPA)-positive polyarticular juvenile idiopathic arthritis (p-JIA). Destructive arthritis progressed during combination therapy with infliximab, methotrexate, mizoribine and prednisolone. Clinical remission was achieved, however, after switching the biologic agent to tocilizumab, a humanized monoclonal antibody to interleukin-6 receptor. Both bone erosion and bone marrow edema on magnetic resonance imaging were repaired in association with restoration of joint spaces. Furthermore, there was no relapse of arthritis on weekly methotrexate alone for 2 years after discontinuation of the tocilizumab. Tocilizumab led to radiological repair of both bone and cartilage destruction and long-term biologics-free remission in a patient with ACPA-positive p-JIA, and should be considered for tumor necrosis factor inhibitor-resistant cases.
26184529 Lymphopenia in early arthritis: Impact on diagnosis and 3-year outcomes (ESPOIR cohort). 2015 Dec OBJECTIVES: In patients with early arthritis naive to disease-modifying antirheumatic drugs, we evaluated the prevalence of initial and persistent lymphopenia, underlying diagnoses, and risk of infection or malignancy. METHODS: Eight hundred and thirteen patients with early arthritis included in the ESPOIR cohort had a clinical examination, laboratory tests (viral serology, immunological tests, and cytokine profile), and radiographs. We determined the prevalence of lymphopenia at baseline and after 3 years, associated factors, diagnoses, and risk of infection or malignancy. RESULTS: At baseline, 50/813 (6.2%) patients had lymphopenia. Lymphopenia was associated with positive rheumatoid factor (P=0.02), cytopenia (P≤0.05), hepatitis C (P=0.05), higher C-reactive protein and DAS28 (P≤0.05 for both). Cytokine profile and radiological progression were not significantly different between patients with and without lymphopenia. Suspected diagnoses at inclusion were rheumatoid arthritis (RA, n=27), unclassified arthritis (n=15), systemic lupus erythematosus (SLE, n=3), spondyloarthritis (n=2), Sjögren's syndrome (n=1), hematologic disease (n=1), and fibromyalgia (n=1). Fifteen patients out of 42 (35.7%) with initial lymphopenia had persistent lymphopenia after 3 years, including 5 with documented causes (lupus, hepatitis C, undernutrition, azathioprine, and tamoxifen); none had PVB19, HIV, or HBV infection and none experienced infections, solid or hematologic malignancies during follow-up. Final diagnoses in these 15 patients were RA (n=6), unclassified arthritis (n=6), SLE (n=1), spondyloarthritis (n=1), and fibromyalgia (n=1). CONCLUSIONS: Lymphopenia is rare in early arthritis. The most common rheumatic cause is RA, in which marked inflammation and other cytopenias are common. Lymphopenia in early arthritis is often short-lived, even when methotrexate is prescribed.
27081318 Reduction in Serum Uric Acid May Be Related to Methotrexate Efficacy in Early Rheumatoid A 2016 OBJECTIVES: The mechanism of action of methotrexate in rheumatoid arthritis (RA) is complex. It may increase adenosine levels by blocking its conversion to uric acid (UA). This study was done to determine if methotrexate lowers UA in early RA (ERA). METHODS: Data were obtained from Canadian Early Arthritis Cohort, an incident ERA cohort. All ERA patients with serial UA measurements were included, comparing those with methotrexate use vs. no methotrexate exposure (controls). Analyses were exploratory. Patients with concomitant gout or taking UA-lowering therapies were excluded. RESULTS: In total, 49 of the 2,524 ERA patients were identified with data available for both pre-methotrexate UA levels and post-methotrexate UA levels (300 µmol/L and 273 µmol/L, respectively; P = 0.035). The control group not taking methotrexate had a mean baseline UA level of 280 µmol/L and a follow-up level of 282 µmol/L (P = 0.448); mean change in UA with methotrexate was -26.8 µmol/L vs. 2.3 µmol/L in the no methotrexate group (P = 0.042). Methotrexate users with a decrease in UA had a disease activity score of 2.37 for 28 joints when compared with the controls (3.26) at 18 months (P = 0.042). Methotrexate users with decreased UA had a lower swollen joint count (SJC) of 0.9 at 18 months, whereas methotrexate users without lowering of UA had an SJC of 4.5 (P = 0.035). Other analyses were not significant. CONCLUSIONS: Methotrexate response is associated with lowering of serum UA in ERA compared to nonusers. This may be due to changes in adenosine levels. Methotrexate response is associated with lower UA and fewer swollen joints compared to nonresponders.
26629366 Discontinuation rates of biologics in patients with rheumatoid arthritis: are TNF inhibito 2015 OBJECTIVE: To compare discontinuation rates of first and second biologics in rheumatoid arthritis (RA) by tumour-necrosis factor inhibitor (TNFi) status and identify predictors and reasons for discontinuation. METHODS: From 1998 to 2011, self-reported medication use for RA was assessed every 6 months via questionnaire in a longitudinal study in the USA. Time-on-drug analyses were conducted for individual biologics and groups, and annual rates reported. Time to discontinuation of TNFi and non-TNFi was compared, unadjusted and adjusted using propensity score analyses. Baseline and time-varying predictors of biologic discontinuation were derived through Cox regression. RESULTS: Of 2281 patients initiating their first biologic, 1100 (48%) discontinued and of 1097 initiating a second biologic, 537 (49%) discontinued. The annual discontinuation rate was 17% (median 4 years) for first biologic and 20% (median 3.3 years) for second biologic. TNFi had lower discontinuation rates than non-TNFi after propensity score adjustment: HR for first biologic 0.49 (0.34 to 0.71) and 0.68 (0.51 to 0.90) for second biologic. The annual discontinuation rate was significantly lower in patients starting their first biologic before January 2005 vs after (16 vs 25%, p=0.005). Predictors of discontinuation for the first biologic included smoking, higher comorbidity index, worse overall health and not using concomitant methotrexate. CONCLUSIONS: In this large cohort, patients with RA tended to remain on their first and second biologics for relatively long periods suggesting the drugs' effectiveness. Discontinuation rates were lower in patients using TNFi, and all rates increased after January 2005 when the number of biologics available increased.
27651926 Metabolomic profiling predicts outcome of rituximab therapy in rheumatoid arthritis. 2016 To determine whether characterisation of patients' metabolic profiles, utilising nuclear magnetic resonance (NMR) and mass spectrometry (MS), could predict response to rituximab therapy. 23 patients with active, seropositive rheumatoid arthritis (RA) on concomitant methotrexate were treated with rituximab. Patients were grouped into responders and non-responders according to the American College of Rheumatology improvement criteria, at a 20% level at 6 months. A Bruker Avance 700 MHz spectrometer and a Thermo Scientific Q Exactive Hybrid Quadrupole-Orbitrap mass spectrometer were used to acquire (1)H-NMR and ultra high pressure liquid chromatography (UPLC)-MS/MS spectra, respectively, of serum samples before and after rituximab therapy. Data processing and statistical analysis were performed in MATLAB. 14 patients were characterised as responders, and 9 patients were considered non-responders. 7 polar metabolites (phenylalanine, 2-hydroxyvalerate, succinate, choline, glycine, acetoacetate and tyrosine) and 15 lipid species were different between responders and non-responders at baseline. Phosphatidylethanolamines, phosphatidyserines and phosphatidylglycerols were downregulated in responders. An opposite trend was observed in phosphatidylinositols. At 6 months, 5 polar metabolites (succinate, taurine, lactate, pyruvate and aspartate) and 37 lipids were different between groups. The relationship between serum metabolic profiles and clinical response to rituximab suggests that (1)H-NMR and UPLC-MS/MS may be promising tools for predicting response to rituximab.
27747496 Assessing Methotrexate Adherence in Rheumatoid Arthritis: A Cross-Sectional Survey. 2015 Jun INTRODUCTION: Limited data are available to explain nonadherence to methotrexate (MTX) therapy in patients with rheumatoid arthritis (RA). Better understanding of patterns of MTX use and reasons for nonadherence may help identify patients who would benefit from alternative RA treatments and potentially aid in developing strategies to increase overall adherence. The purpose of this study was to assess patients' self-reported adherence to MTX and to identify reasons for nonadherence. METHODS: Patient panel members in the US self-reporting a diagnosis of RA of ≥3 months' and current MTX use of ≥4 weeks' duration, with or without concomitant use of another RA prescription medication, participated in this cross-sectional, web-based survey. RESULTS: The sample population (251 MTX monotherapy, 250 MTX combination therapy) was predominantly female, white, non-Hispanic, and educated; 48% were 18-44 years-old, 47% had medical comorbidities, 66% were first diagnosed with RA ≤5 years earlier, 51% reported MTX use of <1 year, and 83% reported oral MTX use. Forty-two percent reported not taking MTX exactly as prescribed. Reasons for nonadherence included forgetting to take it (33%), not needing it when feeling well (24%), and concern about long-term safety (24%). Among nonadherent patients, 53% took smaller doses, 52% skipped doses, and 6% reported other nonprescribed ways of taking MTX. Younger age, male sex, and shorter duration of MTX use were associated with poorer self-reported adherence. Compared with monotherapy patients, combination therapy patients, particularly those taking ≥2 other RA prescriptions, were less likely to report high adherence. CONCLUSION: Nearly half the sample reported poor MTX adherence because they forgot to take it, thought it was not needed when they felt well, or had long-term safety concerns. Patients taking ≥2 other RA prescription medications were less likely to report good adherence. Reducing treatment burden without sacrificing efficacy may be a strategy worth evaluating.
26924198 [Treatment of cardiovascular risk factors]. 2016 Mar Cardiovascular (CV) events are among the most important comorbidities and are the major cause of death in inflammatory rheumatic diseases, such as rheumatoid arthritis (RA). Disease activity and traditional CV risk factors contribute to the total CV risk. Among the antirheumatic drugs used for long-term treatment of RA, non-steroidal anti-inflammatory drugs (NSAID) and glucocorticoids lead to an increased risk but disease-modifying antirheumatic drugs (DMARD), such as hydroxychloroquine, methotrexate and especially biologics significantly reduce the risk. Besides achieving the best possible disease control, rheumatologists should identify additional CV risk factors and also initiate adequate treatment in order to reduce or even eliminate the CV risk. When treating rheumatic diseases possible drug-induced elevation of CV risk must be considered. Finally, the CV risk should be regularly monitored.
27981819 Successful treatment of refractory adult onset Still's disease with rituximab. 2016 Dec 16 Adult-onset Still's disease (AOSD) is an uncommon inflammatory condition of unknown origin. In chronic disease, joint involvement is often predominant and erosions are noted in one third of patients. Therapeutic strategies derive from observational data. Corticosteroids are usually the first-line treatment. With inadequate response to corticosteroids, methotrexate appears the best choice to control disease activity and allow for tapering of steroid use. For refractory disease, biological therapy seems the most promising. We report here the case of a 38-year-old female patient with AOSD refractory to cytotoxic agents, treated by rituximab infusion therapy with favorable outcome.
28243292 Does Regular Use of a Complementary Medicine of Olea Europe and Ficus carica Have Adverse 2016 Fall Rheumatoid arthritis (RA) patients are vulnerable to cardiovascular morbidity and mortality in which atherosclerosis plays a major role. In this study, the lipid profile and fasting blood sugar (FBS) of RA patients receiving a complementary medicine of olive and fig, as add-on therapy for routine disease-modifying antirheumatic drugs (DMARDs) regimen containing low dose methotrexate (MTX), were studied. A randomized controlled clinical trial was designed. Adult RA patients were randomly allocated in two groups receiving routine DMARDs regimen (control group) and routine DMARDs regimen plus the herbal supplementary formulation of olive oil, fig and olive fruits (intervention group). Patients were followed every 4 weeks for total study period of 16 weeks. In addition to demographic and medical history of the patients, the total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglyceride (TG), the atherogenic index of plasma (AIP) defined as log(TG/HDL-C), and the fasting blood sugar (FBS) were determined and recorded. 56 patients (control = 27 and intervention = 29), with mean ± sd age of 50.9 ± 12.3 years completed the study. Average MTX dose received by intervention and control groups were 24.30 ± 18.39 and 17.61 ± 15.53 mg/week, respectively (p = 0.11). Repeated measures analysis of variance (ANOVA) revealed that differences between lipid profile indicators and FBS in the two study groups were not statistically significant (P>0.05). No additional substantial adverse reaction was seen in the study groups. Our findings are more reassuring for patients and their doctors to trust on the safety of the investigated complementary preparation to be used as add-on therapy to manage rheumatoid arthritis.
27274398 Preliminary study for predicting better methotrexate efficacy in Japanese patients with rh 2016 BACKGROUND: Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by systemic inflammatory status, joint destruction, disability, and pain. Methotrexate (MTX) has been confirmed to reduce disease activity and delay or stabilize the development of bone erosions. However, major drawbacks are that patients show great interindividual variability in response to MTX and the unpredictable occurrence of side effects. A strategy for personalized MTX treatment to predict its efficacy and toxicity has not yet been determined. To establish personalized MTX therapy in Japanese patients with rheumatoid arthritis, we performed a preliminary study for predicting better methotrexate efficacy including single-nucleotide polymorphisms (SNPs) for MTX-related transporters/enzymes. METHODS: Disease control status (good or poor) was judged by the number of Disease Activity Scores (DAS28) of <2 for 6-12 months. The response index R was calculated by the improved area under the curve (AUC) of the DAS28 score for 0-3 or 0-6 months by dividing the cumulative dose of MTX during 0-3 or 0-6 months, respectively. Genotyping of alleles of RFC1 80G > A, RFC1 -43 T > C, FPGS 1994G > A, GGH 401C > T, MTHFR 1298A > C, and TYMS 3'-UTR (-6/+6) was performed using the real-time PCR system. RESULTS: Seven of 21 patients were judged as good responders in terms of disease control, and the remainder as poor responders. For 0-3 months after starting MTX administration, the median cumulative dose and improved DAS28 AUC in the good and poor response groups were 96.0 mg and 25.4 and 118.0 mg and 23.4, respectively. For 0-6 months, the median cumulative dose and improved DAS28 AUC in the good and poor response groups were 192.0 mg and 51.0 and 214.0 mg and 47.6, respectively. Statistically significant differences between the 2 groups in the 0-6-month period were observed in DAS28 AUC improvement and index R. A slight tendency for a correlation between G/G genotypes and A allele genotypes in RFC1 80 genotypes was observed, although it did not reach statistical significance. CONCLUSION: This study suggested that aggressive RA treatment with MTX from the early period of administration is necessary to obtain a good response after 6 months, although no SNPs predicting a better treatment response to MTX were identified.
