26255186 | Clinical and laboratory factors associated with interstitial lung disease in rheumatoid ar | 2015 Sep | OBJECTIVE: The objective of this study is to examine the clinical, genetic, and environmental factors associated with interstitial lung disease (ILD) in rheumatoid arthritis (RA). METHOD: We recruited patients with RA from rheumatology practices at the time of a scheduled visit. Each patient participated in a comprehensive assessment that included ascertainment of age, sex, joint tenderness and swelling, subcutaneous nodules, disease severity, use of methotrexate and prednisone, smoking status, rheumatoid factor (RF), antibodies against cyclic citrullinated peptide (anti-CCP),erythrocyte sedimentation rate (ESR), the 28-joint Disease Activity Score (DAS28), and the presence of the HLA-DRB1 shared epitope (SE). As part of a thorough quantification of comorbidity, we identify all comorbid conditions, including ILD. We examined variables associated with ILD using logistic regression. We tested interaction terms between SE and other covariates. RESULTS: We studied 779 RA patients, among whom, ILD was recognized clinically in 69 (8.8 %). Variables significantly associated with ILD in a multivariable analysis included male sex, RA duration, the ESR, the DAS28, anti-CCP, and RF. There was a significant interaction between the HLA-DRB1 SE and smoking, ILD being associated with smoking only in the presence of SE. The association between ILD and anti-CCP, RF, and the ESR displayed a biological gradient, higher titers being more strongly associated with ILD. CONCLUSION: Anti-CCP antibodies and the RF may be pathogenically related to ILD. The association between ILD and smoking is dependent on the HLA-DRB1 SE, which may reflect gene-environment interaction. | |
25228126 | Glucocorticoids in early rheumatoid arthritis: are the benefits of joint-sparing effects o | 2015 | This paper reviews the clinical effects on bone of 10 mg of prednisone daily in early rheumatoid arthritis, given for 2 years in the Utrecht Study and in the second CAMERA (Computer- Assisted Management in Early Rheumatoid Arthritis) Study, and addresses the question whether there were joint-sparing effects and whether these were offset by adverse effects, especially osteoporosis. We conclude that a 2-year adjunct treatment with 10 mg of prednisone daily increases the benefits of disease-modifying antirheumatic drug therapy and has joint-sparing properties, even if added to the tight control methotrexate-based strategy aiming for remission. Importantly, with good control of inflammation and adequate use of calcium, vitamin D and bisphosphonates - according to national or international guidelines - steroid-induced osteoporosis is rare over 2 years. | |
27648596 | Age at natural menopause in women on long-term methotrexate therapy for rheumatoid arthrit | 2016 Oct | OBJECTIVE: The aim of the study was to compare the natural menopause ages of healthy women with those of women with methotrexate (MTX)-treated rheumatoid arthritis (RA), and to specifically assess the effect of disease onset and activity and the use of MTX on the age of the last menstruation. METHODS: We performed a retrospective review of medical records to identify the ages at which menopause occurred in women with premenopausal RA treated with MTX and in women with postmenopausal onset, irrespective of therapy. Natural menopause ages were also compared between participants with and without RA. RESULTS: Women with premenopausal onset of RA underwent menopause at a significantly younger age than did healthy women (P < 0.001) or those with postmenopausal disease onset (P = 0.001). Menopause also occurred at younger ages in participants with postmenopausal disease onset than in healthy controls (P = 0.012). The study suggested that menopause age was positively correlated with the age at which RA was diagnosed (R = 0.51; P < 0.001) in women with premenopausal RA onset, but was independent of the participant's age at menarche, number of pregnancies, or MTX therapy. Participants with RA onset at ≤ 35 years of age had a ninefold higher risk of premature menopause (P = 0.008). CONCLUSIONS: The age at which menopause occurs in a patient with RA depends on the patient's age at the time of disease onset and its duration, but is not influenced by MTX treatment. | |
25721751 | Methotrexate-associated lymphoproliferative disorders: management by watchful waiting and | 2015 | No optimum treatment of iatrogenic immunodeficiency-associated lymphoproliferative disorders due to methotrexate in patients with rheumatoid arthritis (MTX-LPD) has yet been established, although MTX withdrawal is known to have a substantial effect on tumor regression. Here, we retrospectively analyzed 20 cases of MTX-LPD. Tumor shrinkage occurred in 18 of 20 cases, but only following MTX withdrawal. This tumor regression ratio was considerably better than in previous reports, and appeared due to longer "watchful waiting." Lymphocyte recovery at 2 weeks after MTX withdrawal was significantly higher in cases with tumor regression in 1 month than in those without tumor regression (p = 0.001). Median time to maximal efficacy after MTX cessation in cases without chemotherapy was 12 weeks (range 2-76). In conclusion, watchful waiting for a longer period after MTX cessation with observation of early lymphocyte recovery and uninterrupted continuation of other anti-rheumatoid drugs may be an acceptable management plan for MTX-LPD. | |
26686022 | Subcutaneous administration of methotrexate at high doses makes a better performance in th | 2016 Jun | OBJECTIVES: This study was conducted to determine whether subcutaneous (SC) methotrexate (MTX) makes better performance on bioavailability, clinical efficiency, side effects occurrence, and treatment failure in the treatment of RA compared with oral MTX. METHODS: The databases PubMed, Web of Science, Embase, and Cochrane Library were systematically searched. Seven studies involving 1335 patients were eligible for data extraction and meta-analysis. The outcomes of meta-analysis were presented as mean difference (MD) or odd ration (OR) with 95% confidence interval (95% CI). RESULTS: Meta-analysis showed that SC MTX can significantly increase the AUC0-t (area under plasma concentration curve from administration to last observed concentration at time t) (MD = 506.84; 95% CI: 80.80-932.89), shorten the time to reach maximum observed concentration (Tmax) (MD = -0.13; 95% CI: -0.25 to -0.01) and the apparent terminal elimination half-life (t(1/2)) (MD = -0.39; 95% CI: -0.70 to -0.08), reduce the occurrence of nausea (OR = 0.53; 95% CI: 0.28-0.97) and diarrhea (OR = 0.43; 95% CI: 0.20-0.95), improve the American College of Rheumatology criteria for 20% improvement (ACR20) (OR = 1.68; 95% CI: 1.09-2.61) and ACR70 (OR = 1.52; 95% CI: 1.02-2.26), and relieve the pain (MD = -0.65; 95% CI: -0.93 to -0.37) compared with oral MTX. However, the differences in maximum plasma concentration (Cmax), the occurrence of headache, vomiting and dyspepsia, ACR50, treatment failure were not significant between the two groups. CONCLUSION: SC route of MTX at high doses made better performance on improving the bioavailability and clinical efficacy, reducing the GI disorders, but it cannot decrease the treatment failure when compared with oral administration of MTX. | |
26616421 | Folate metabolic pathway single nucleotide polymorphisms: a predictive pharmacogenetic mar | 2015 Dec | AIM: We evaluated the pharmacogenetic influence of genetic polymorphisms in folate pathway genes in Indian rheumatoid arthritis patients receiving methotrexate (MTX). PATIENTS & METHODS: Twelve polymorphisms within nine folate pathway genes were analyzed for association with MTX response in 322 Indian rheumatoid arthritis (RA) patients and MTX pharmacokinetics in 94 RA patients. RESULTS: Polymorphisms in GGH, SHMT1 and TS were associated with MTX-related adverse events while SNPs in MTHFR and RFC1/SLC19A1 were associated with MTX efficacy. TS5'UTR and SHMT1 polymorphisms were associated with higher plasma levels of MTX. CONCLUSION: Polymorphisms in folate-MTX pathway genes contribute to MTX response and affect MTX concentrations in Indian RA patients. A toxicogenetic index could identify patients who develop adverse events to MTX. | |
26337028 | Serum RANKL levels associate with anti- citrullinated protein antibodies in early untreate | 2015 Sep 4 | INTRODUCTION: Receptor activator of nuclear factor kappa B ligand (RANKL) is a key regulator of bone metabolism. Anti-citrullinated protein antibodies (ACPA) have been suggested to cause bone destruction by osteoclast activation. We investigated the relationship between RANKL and ACPA in patients with early untreated rheumatoid arthritis (RA). METHODS: Patients with newly diagnosed untreated RA (n = 183) were analyzed at baseline and 3 months after initiating methotrexate (MTX) treatment. Serum RANKL (total RANKL), ACPA (anti-CCP2) and ACPA specificities (anti-citrullinated (cit)-vimentin, anti-cit-enolase and anti-cit-fibrinogen) were determined by enzyme-linked immunosorbent assay (ELISA). Synovial RANKL expression was evaluated by immunohistochemistry in a small group of patients (n = 15). The relationship between anti-cit-vim antibodies and bone destruction was further validated in 1116 RA patients included in the EIRA cohort. Pearson's chi-square test, Wilcoxon rank sum test, Wilcoxon signed rank test and linear regression models were used. RESULTS: Serum RANKL concentration was significantly higher (p <0.05) in ACPA-positive (median: 689 pmol/L, IQR 342-1253) compared with ACPA-negative (median: 159 pmol/L, IQR 96-243) patients and this difference was also seen for synovial RANKL expression. Serum RANKL associated with ACPA (p <0.05) and bone erosions in rheumatoid factor (RF)-negative patients (n = 59). Among ACPA specificites, anti-cit-vimentin (amino acids 60-75) was associated with higher RANKL concentration and higher prevalence of bone erosion (p <0.05). Significant reductions in both serum RANKL and ACPA levels were observed after 3 months of MTX treatment (p <0.05). CONCLUSIONS: RANKL was elevated in ACPA-positive and in anti-cit-vimentin-positive patients with early untreated RA and associated with bone erosions. These findings give further support for an early direct pathogenic link between ACPA and bone destruction in RA. | |
26961485 | Efficacy and safety of low-dose tacrolimus for active rheumatoid arthritis with an inadequ | 2016 Jul | BACKGROUND/AIMS: To determine the efficacy and safety of low-dose tacrolimus in Korean rheumatoid arthritis (RA) subjects with an inadequate response to methotrexate (MTX). METHODS: This was a multicenter, open-label study conducted at five Korean sites. Fifty-six patients with active RA, despite treatment for ≥ 1 month with a stable, maximally tolerated dosage of oral MTX (median dosage, 15 mg/wk), were enrolled and received 1.5 mg/day of tacrolimus as a single oral dose once per day for 16 weeks while continuing to receive MTX. All other disease-modifying anti-rheumatic drugs were discontinued, whereas stable dosages of nonsteroidal anti-inflammatory drugs and oral corticosteroids (≤ 10 mg/day of prednisone or an equivalent corticosteroid) were allowed. The primary clinical response criterion was the American College of Rheumatology's definition of 20% improvement (ACR20) at the end of treatment. RESULTS: The ACR20 response rate was 42.9% (24 of 56 patients) in patients who had received tacrolimus at least once. The overall ACR50 and ACR70 responses at the end of treatment for all patients were 30.4% and 10.7%, respectively. Throughout the treatment period, 37 patients experienced 71 adverse events (AEs) in total, and four patients left the study because of AEs. In addition, 15 patients in total experienced treatment-related AEs. Throughout the treatment period, two patients were reported to experience two serious AEs, and one patient left the study because of a serious AE. CONCLUSIONS: In patients whose active RA persists despite treatment with MTX, low-dose tacrolimus in combination with MTX appears to be safe and well tolerated, and provides clinical benefit. | |
25118313 | Methotrexate-mediated inhibition of nuclear factor κB activation by distinct pathways in | 2015 Jan | OBJECTIVES: Nuclear factor κB (NF-κB) is a critical activator of inflammatory processes and MTX is one of the most commonly prescribed DMARDs for treatment of RA. We sought to determine whether MTX inhibited NF-κB activity in RA and in lymphocytes and fibroblast-like synoviocytes (FLSs) and to define underlying mechanisms of action. METHODS: An NF-κB luciferase reporter plasmid was used to measure NF-κB activation across experimental stimuli. Flow cytometry was used to quantify changes in intracellular protein levels, measure levels of reactive oxygen species and determine apoptosis. Quantitative RT-PCR was used to identify changes in MTX target genes. RESULTS: In T cell lines, MTX (0.1 μM) inhibited activation of NF-κB via depletion of tetrahydrobiopterin (BH4) and increased Jun-N-terminal kinase (JNK)-dependent p53 activity. Inhibitors of BH4 activity or synthesis also inhibited NF-κB activation and, similar to MTX, increased JNK, p53, p21 and JUN activity. Patients with RA expressed increased levels of phosphorylated or active RelA (p65) compared with controls. Levels of phosphorylated RelA were reduced in patients receiving low-dose MTX therapy. In contrast, inhibition of NF-κB activation by MTX was not mediated via BH4 depletion and JNK activation in FLSs, but rather was completely prevented by adenosine receptor antagonists. CONCLUSION: Our findings support a model whereby distinct pathways are activated by MTX in T cells and FLSs to inhibit NF-κB activation. | |
25793532 | Defining immunological impact and therapeutic benefit of mild heating in a murine model of | 2015 | Traditional treatments, including a variety of thermal therapies have been known since ancient times to provide relief from rheumatoid arthritis (RA) symptoms. However, a general absence of information on how heating affects molecular or immunological targets relevant to RA has limited heat treatment (HT) to the category of treatments known as "alternative therapies". In this study, we evaluated the effectiveness of mild HT in a collagen-induced arthritis (CIA) model which has been used in many previous studies to evaluate newer pharmacological approaches for the treatment of RA, and tested whether inflammatory immune activity was altered. We also compared the effect of HT to methotrexate, a well characterized pharmacological treatment for RA. CIA mice were treated with either a single HT for several hours or daily 30 minute HT. Disease progression and macrophage infiltration were evaluated. We found that both HT regimens significantly reduced arthritis disease severity and macrophage infiltration into inflamed joints. Surprisingly, HT was as efficient as methotrexate in controlling disease progression. At the molecular level, HT suppressed TNF-α while increasing production of IL-10. We also observed an induction of HSP70 and a reduction in both NF-κB and HIF-1α in inflamed tissues. Additionally, using activated macrophages in vitro, we found that HT reduced production of pro-inflammatory cytokines, an effect which is correlated to induction of HSF-1 and HSP70 and inhibition of NF-κB and STAT activation. Our findings demonstrate a significant therapeutic benefit of HT in controlling arthritis progression in a clinically relevant mouse model, with an efficacy similar to methotrexate. Mechanistically, HT targets highly relevant anti-inflammatory pathways which strongly support its increased study for use in clinical trials for RA. | |
24737786 | Cost-effectiveness of infliximab versus conventional combination treatment in methotrexate | 2015 Jun | OBJECTIVE: To estimate the incremental cost-effectiveness of infliximab versus conventional combination treatment over 21 months in patients with methotrexate-refractory early rheumatoid arthritis. METHODS: In this multicentre, two-arm, parallel, randomised, active-controlled, open-label trial, rheumatoid arthritis patients with <1 year symptom duration were recruited from 15 rheumatology clinics in Sweden between October 2002 and December 2005. After 3-4 months of methotrexate monotherapy, patients not achieving low disease activity were randomised to addition of infliximab or sulfasalazine+hydroxychloroquine (conventional treatment group). Costs of drugs, healthcare use, and productivity losses were retrieved from nationwide registers, while EuroQol 5-Dimensions utility was collected quarterly. RESULTS: Of 487 patients initially enrolled, 128 and 130 were randomised to infliximab and conventional treatment, respectively. The infliximab group accumulated higher drug and healthcare costs (€27,487 vs €10,364; adjusted mean difference €16,956 (95% CI 14,647 to 19,162)), while productivity losses did not differ (€33,804 vs €29,220; €3961 (95% CI -3986 to 11,850)), resulting in higher societal cost compared to the conventional group (€61,291 vs €39,584; €20,916 (95% CI 12,800 to 28,660)). Mean accumulated quality-adjusted life-years (QALYs) did not differ (1.10 vs 1.12; adjusted mean difference favouring infliximab treatment 0.01 (95% CI -0.07 to 0.08)). The incremental cost-effectiveness ratios for the infliximab versus conventional treatment strategy were €2,404,197/QALY from the societal perspective and €1,948,919/QALY from the healthcare perspective. CONCLUSIONS: In early, methotrexate-refractory rheumatoid arthritis, a treatment strategy commencing with addition of infliximab, as compared to sulfasalazine+hydroxychloroquine, was not cost-effective over 21 months at willingness to pay levels generally considered acceptable.

24833784 | Fertility in women with rheumatoid arthritis: influence of disease activity and medication | 2015 Oct | OBJECTIVES: Many female rheumatoid arthritis (RA) patients attempting to conceive have a time to pregnancy (TTP) of >12 months. During this period RA often cannot be treated optimally. We sought to identify clinical factors associated with prolonged TTP in female RA patients. METHODS: In a nationwide prospective cohort study on pregnancy in RA patients (PARA study), women were included preconceptionally or during the first trimester. Cox regression analysis was used to study the association of disease characteristics and medication use with TTP. RESULTS: TTP exceeded 12 months in 42% of 245 patients. Longer TTP was related to age, nulliparity, disease activity (DAS28), and preconception use of non-steroidal anti-inflammatory drugs (NSAIDs) and prednisone. These variables were independently associated with TTP, with HRs for occurrence of pregnancy of 0.96 (95% CI 0.92 to 1.00) per year of age, 0.52 (0.38 to 0.70) for nulliparity, 0.81 (0.71 to 0.93) per point increase in DAS28, 0.66 (0.46 to 0.94) for NSAIDs and 0.61 (0.45 to 0.83) for prednisone use. The impact of prednisone use was dose dependent, with significantly longer TTP when daily dose was >7.5 mg. Smoking, disease duration, rheumatoid factor, anti-citrullinated protein antibodies, past methotrexate use, and preconception sulfasalazine use did not prolong TTP. CONCLUSIONS: TTP in RA is longer if patients are older or nulliparous, have higher disease activity, use NSAIDs or use prednisone >7.5 mg daily. Preconception treatment strategies should aim at maximum suppression of disease activity, taking account of possible negative effects of NSAIDs use and higher prednisone doses. | |
26269292 | Assessment of Substantial Liver Fibrosis by Real-time Shear Wave Elastography in Methotrex | 2015 Sep | OBJECTIVES: A concern about methotrexate (MTX)-related liver fibrosis in patients with rheumatoid arthritis (RA) is still unresolved. This study investigated the correlation between liver stiffness and the cumulative MTX dose and the risk factors associated with substantial liver fibrosis assessed by real-time shear wave elastography (SWE), a recently introduced technique to evaluate liver stiffness in patients with RA. METHODS: Data from 185 patients with RA were prospectively collected. Patients were divided into 3 groups according to cumulative MTX dose (group 1, total dose <1500 mg; group 2, 1500-4000 mg, and group 3, >4000 mg) and compared with healthy control participants. A Pearson correlation analysis was performed to evaluate correlations between liver stiffness and other clinical and laboratory variables. Substantial liver fibrosis was defined as liver stiffness of greater than 8.6 kPa by SWE. Associated factors were tested in a multivariate logistic analysis. RESULTS: The mean liver stiffness value in healthy controls was significantly lower than in patients with RA treated with MTX (P< .006), but there was no significant difference among the MTX groups. Liver stiffness and the cumulative MTX dose was not correlated. Substantial liver fibrosis was detected only in 9 patients (4.9%). Multivariate analysis adjusted by age and sex revealed that only a high body mass index (odds ratio, 1.79; 95% confidence interval, 1.34-2.39; P < .001) was associated with liver stiffness of greater than 8.6 kPa. CONCLUSIONS: Substantial liver fibrosis on SWE was observed in about 5% of MTX-treated patients with RA and was associated with only a high body mass index but not with the cumulative MTX dose, suggesting that other comorbidities might have a more important role in liver fibrosis. | |
26361879 | Two-year radiographic and clinical outcomes from the Canadian Methotrexate and Etanercept | 2016 Feb | OBJECTIVE: To evaluate radiographic and clinical outcomes up to 24 months in patients with RA enrolled in the Canadian Methotrexate and Etanercept Outcome study. METHODS: In this open-label non-inferiority trial, patients with inadequate response to MTX received etanercept plus MTX for 6 months and then were randomized to either etanercept monotherapy or continued etanercept plus MTX until 24 months. Radiographic data were analysed using the modified total Sharp score (mTSS), joint space narrowing and erosion scores. Secondary outcomes included the 28-joint DAS with ESR (DAS28-ESR), Simplified Disease Activity Index, Clinical Disease Activity Index, HAQ Disability Index (HAQ-DI) and safety. RESULTS: Two hundred five of 258 patients enrolled were randomized (98 etanercept, 107 etanercept plus MTX). At month 24, the mean increase from baseline to month 24 for the etanercept and etanercept plus MTX arms, respectively, for the mTSS were 0.4 (s.d. 1.9) and 0.0 (s.d. 1.4); for joint space narrowing, 0.1 (s.d. 0.6) and 0.0 (s.d. 0.7) and for erosion, 0.3 (s.d. 1.5) and 0.0 (s.d. 1.0). At month 24, the mean increase from month 6 mean scores/count increases for DAS28-ESR were 0.56 (s.d. 1.26) and 0.08 (s.d. 1.50); for Simplified Disease Activity Index, 4.7 (s.d. 13.1) and 0.9 (s.d. 12.5); for Clinical Disease Activity Index, 4.1 (s.d. 12.3) and 1.0 (s.d. 12.3) and for HAQ-DI, 0.20 (s.d. 0.45) and 0.02 (s.d. 0.54). Patients with DAS28-ESR low disease activity (LDA)/remission at month 6 had numerically better outcomes at month 24 than patients with moderate to high disease activity at month 6. In patients with LDA/remission at month 6, outcomes were similar at month 24 between etanercept monotherapy and etanercept plus MTX, whereas patients with moderate to high disease activity at month 6 had numerically better outcomes with etanercept plus MTX than etanercept at month 24. There were no new safety signals and serious adverse events were not different between groups. CONCLUSION: These results support the possibility of discontinuing MTX in patients who have tolerability issues with MTX if they achieve LDA/remission.

26794605 | Two-year results of disease activity score (DAS)-remission-steered treatment strategies ai | 2016 Jan 21 | BACKGROUND: Early suppression of disease activity in (rheumatoid) arthritis (RA) patients may result in drug-free remission and prevent damage. We assessed 2-year clinical and radiological outcomes of two disease activity score (DAS)-remission-steered treatment strategies in early arthritis patients. METHODS: Patients (n = 610) with early RA or undifferentiated arthritis (UA) were treated with methotrexate (MTX) and tapered high dose of prednisone. Patients in early remission (44/53 joints DAS <1.6) after 4 months tapered and stopped medication. Patients who did not achieve early DAS-remission were randomized to either MTX plus hydroxychloroquine plus sulphasalazine plus low dose prednisone (arm 1) or to MTX + adalimumab (arm 2). At four-monthly intervals, medication was tapered and stopped if DAS was <1.6 but restarted, increased or switched if DAS was ≥1.6. Proportions of (drug-free) DAS-remission (DFR) after 2 years and Sharp-van der Heijde scores (SHS) were analyzed separately for the treatment strategies and patients with RA and UA. RESULTS: After 2 years, 301/610 (49 %) patients were in DAS-remission and 131/610 (21 %) in DFR. In the early remission group 241/387 patients (62 %) were in DAS-remission and 111/387 (29 %) DFR. In arm 1 22/83 (27 %) and in arm 2 24/78 (31 %) were in DAS-remission, and 6/83 (7 %) and 7/78 (9 %), respectively, were in DFR. RA and UA patients achieved DAS-remission in comparable percentages (RA: 234/479 (49 %), UA: 64/122 (52 %), p = 0.25). More UA patients achieved DFR (41/122 (34 %)) compared to RA patients (89/479 (19 %), p<0.001). Mean (SD) DAS over time was 1.74 (0.58) across all patients, and median (IQR) SHS progression was 0 (0-0). CONCLUSIONS: After 2 years remission-steered treatment in early RA and UA patients, DAS-remission and DFR percentages were relatively low. Patients who achieved early remission more often achieved (drug-free) remission after 2 years than patients who needed additional treatment steps in the randomization arms, and more UA than RA patients achieved DFR. Overall, disease activity and radiologic damage progression in all patients were well suppressed.

27178257 | Predicting the probability of successful efficacy of a dissociated agonist of the glucocor | 2016 Jun | PF-04171327 is a dissociated agonist of the glucocorticoid receptor (DAGR) being developed to retain anti-inflammatory efficacy while reducing unwanted effects. Our aim was to conduct a longitudinal dose-response analysis to identify the DAGR doses with efficacy similar to or greater than prednisone 10 mg once daily (QD). The data included were from a Phase 2, randomized, double-blind, parallel-group study in 323 subjects with active rheumatoid arthritis on a background of methotrexate. Subjects received DAGR 1, 5, 10 or 15 mg, prednisone 5 or 10 mg, or placebo QD for 8 weeks. The Disease Activity Score 28-4 calculated using C-Reactive Protein (DAS28-4 CRP) was the efficacy endpoint utilized in this dose-response model. For DAGR, the maximum effect (Emax) on DAS28-4 CRP was estimated to be -1.2 points (95 % CI -1.7, -0.84), and the evaluated dose range provided 31-87 % of the Emax; for prednisone 5 and 10 mg, the estimated effects were -0.27 (95 % CI -0.55, 0.006) and -0.94 point (95 % CI -1.3, -0.59), respectively. Stochastic simulations indicated that the DAGR 1, 5, 10 and 15 mg have probabilities of 0.9, 29, 54 and 62 %, respectively, to achieve efficacy greater than prednisone 10 mg at week 8. DAGR 9 mg estimated probability was 50 % suggesting that DAGR ≥9 mg QD has an effect on DAS28-4 CRP comparable to or greater than prednisone 10 mg QD. This work informs dose selection for late-stage confirmatory trials. | |
27181240 | [Allergic bronchopulmonary aspergillosis in a patient with rheumatoid arthritis under adal | 2016 | A 77-year-old woman with a 15-year history of rheumatoid arthritis (RA) was admitted to our hospital because of a wet cough that persisted for 1 month. The patient had been taking methotrexate (MTX) and adalimumab (ADA) for the past 3 years, and disease activity of RA was low. Discontinuation of ADA and MTX and treatment with oral levofloxacin were not effective. On admission, laboratory examinations showed eosinophilia (2539/μL), elevated serum total immunoglobulin E (538.0 IU/ml) and Aspergillus-specific immunoglobulin E levels, and Aspergillus fumigatus serum precipitins. A chest radiograph revealed multiple bilateral pulmonary shadows, and computed tomography revealed multiple consolidations. Bronchoscopic examination showed mucous plugs. Pathological examination revealed diffuse infiltration of eosinophils and fungus in the plugs. These findings led to the diagnosis of allergic bronchopulmonary aspergillosis (ABPA). A combination of prednisolone (0.5 mg/kg/day) and itraconazole (200 mg/day) was administered. After 3 months, the pulmonary consolidations resolved. To our knowledge, this is the first report of ABPA in a patient with RA treated with ADA. If patients treated with biologic disease-modifying antirheumatic drugs present with eosinophilia and pulmonary consolidations, clinicians should consider ABPA in the differential diagnosis. | |
25593236 | Incidence of malignancy and the risk of lymphoma in Japanese patients with rheumatoid arth | 2015 Apr | OBJECTIVE: Recent advances in the management of patients with rheumatoid arthritis (RA) increased the rates of disease remission and patient life expectancy, while malignancy has become a more common cause of death. Here, we report the incidence of malignancy in a nationwide survey of Japanese patients with RA compared to the general population, focusing on the risk of lymphoma, which often arises in patients with RA. METHODS: Data on the occurrence of malignancy were collected from patients registered in a nationwide Japanese cohort database, the National Database of Rheumatic Diseases by iR-net in Japan, from 2003 to 2012. To adjust for different population composition and to compare the incidence of malignancy with the general population, standardized incidence rates (SIR) were calculated. To identify risk factors for lymphoma, individual patient data were obtained for multivariate analysis for the year before lymphoma diagnosis. RESULTS: In 10 years, the cohort composed of 66,953 patient-years yielded 559 malignancies, most frequently lung cancer, followed by gastric cancer, breast cancer, and lymphoma. The overall incidence of malignancies in patients with RA was slightly lower than in the general population (SIR 0.89, 95% CI 0.82-0.97). However, lymphoma risk was significantly higher (SIR 3.43, 95% CI 2.59-4.28), whereas risk of colon, rectal, or liver cancer was lower. Significant risk factors for lymphoma were the use of methotrexate or tacrolimus, and higher age. CONCLUSION: Patients with RA had no higher overall incidence of malignancies, but lymphoma was significantly more frequent than in the general population. | |
26052803 | The usefulness of a new triple combination treatment utilizing methotrexate, salazosulfapy | 2016 | OBJECTIVES: Combination treatment with methotrexate, salazosulfapyridine and bucillamine as an alternative to treatment with TNF-inhibiting biologics in rheumatoid arthritis was investigated. METHODS: Twenty-six facilities allied with the Japan Association of Rheumatologists in Private Practice participated in this study. One hundred and twelve patients enrolled in this study, all of whom were within 3 years of diagnosis with rheumatoid arthritis for whom treatment with one DMARD or a combination of two DMARDs had failed (DAS28 > 3.2). Patients chose their own treatment. The triple DMARDs combination group was comprised of 72 patients; the TNF-inhibiting biologics treatment group was comprised of 40 patients. RESULTS: DAS28 scores for the triple DMARDs combination group and the TNF-inhibiting biologics treatment groups were 4.84 ± 0.96 and 5.23 ± 1.26, and there was no significant difference between the two groups. From the 6th month, average disease activities of both groups were reduced, and there was no difference between the two groups at 12 months (DAS28, 3.39 ± 1.43 and 3.05 ± 1.43, p = 0.39). Furthermore, there was no significant difference in the degree of bone destruction between the two groups at 12 months. CONCLUSIONS: The triple DMARD combination therapy provided a new treatment option for those patients for whom treatment with biologics is difficult. | |
26028387 | Anti inflammatory effect of thymoquinone in comparison with methotrexate on pristane induc | 2015 May | OBJECTIVE: To determine the anti-inflammatory effects of thymoquinone on body weight, clinical score of inflammation, total leukocyte count and differential leukocyte count in arthritic rats and compare it with that of methotrexate. METHODS: The study was conducted at the Post-Graduate Medical Institute, Lahore, from March to September 2013, and comprised female Sprague-Dawley rats randomised into four equal groups; group A (healthy control), group B (positive control), group C (thymoquinone treated) and group D (methotrexate treated). Arthritis developed in Group B, C and D within two weeks after a single intra-dermal injection of pristane. Body-weight measured on electronic balance in grams and clinical score of inflammation scored on macroscopic scoring system were monitored on every alternate day while total leukocyte count and differential leukocyte count were taken at day 0, 16 and 30. After day 15, groups A and B were given 0.5ml of distilled water by intra-peritoneal injection daily for 15 consecutive days; group C was given thymoquinone 2mg/kg by intra-peritoneal injection daily for 15 consecutive days, and group D received methotrexate 0.5mg/kg by intra-peritoneal injection, daily for 15 consecutive days. SPSS 20 was used for statistical analysis. RESULTS: The 32 rats in the study were randomised into four groups of 8(25%) each. In group A the body-weight continued to increase and reached a mean of 144.13±10.8% of the baseline at day 30. In group B the weight reduced to 93.13±4.19% at day 16 and to 88.3±6.97% at day 30. In groups C and D the weight reduced to 87.25±7.69% and 88.5±7.07% respectively at day 16; then the animals in the two groups regained their weight which increased to 108.63±10.89% and 103.38±6.25% respectively at day 30. The score was zero in group A throughout the study period. The score of group B, which was zero at day 0, reached a mean of 16±0 at day 16. In groups C and D, the mean score increased till day 16 and reached 16±1 and 16±0 respectively, and then reduced to 5±2 and 4±1 at day 30 respectively. CONCLUSIONS: Evaluation of data supported the anti-inflammatory activities of thymoquinone, so it may be investigated as an effective anti-inflammatory drug in rheumatoid arthritis. |
