RESUMO

OBJECTIVE: This study aimed to explore the cost-effectiveness of etanercept plus methotrexate (ETN+MTX) compared to triple disease-modifying anti-rheumatic drugs (DMARDs) in treating Chinese rheumatoid arthritis (RA) patients. METHODS: The 134 Chinese RA patients who were about to initiate ETN+MTX or triple DMARDs therapy based on treat-to-target strategy were consecutively recruited and categorized into ETN+MTX group (N = 49) or triple DMARDs group (N = 85). Treatment efficacy was assessed at month 3 (M3)/M6/M9/M12 after initiation of treatment. Also, 1-year treatment cost was evaluated, and cost-effectiveness analysis and sensitivity analysis were conducted. RESULTS: RA patients in ETN+MTX group exhibited similar disease activity and quality of life at each time point while elevated 28-joint disease activity score based on erythrocyte sedimentation rate (DAS28-ESR) change (M0-M12) and low disease activity rate compared with triple DMARDs group. For 1-year treatment cost, ETN+MTX required increased drug cost, decreased other medical cost, and finally elevated total cost compared with triple DMARDs. Meanwhile, compared to triple DMARDs, ETN+MTX produced an additional quality-adjusted life year (QALY) of 0.015, resulting in an incremental cost-effectiveness ratio (ICER) of ¥2,939,506.7 per QALY that was 53.1 folds of gross domestic product (GDP) per capita in China. More interestingly, sensitivity analysis revealed that the ETN price had to be reduced at least by 71.3% before ETN+MTX became cost-effectiveness compared to triple DMARDs. CONCLUSION: ETN+MTX is less cost-effective in treating Chinese RA patients compared with triple DMARDs.

RESUMO

Objectives: The objective of this study was to calculate adherence, persistence and 10-year switches in patients with PsA, by comparing adalimumab and etanercept in real life.Methods: The authors conducted a retrospective, observational, pharmacological and non-interventional study taking into consideration the dispensations of the study drugs at the Hospital Pharmacy, from 1 January 2007 to 31 December 2018. In the study, the authors considered adalimumab and etanercept. The authors calculated adherence to treatment through the relationship between received daily dose (RDD) and prescribed daily dose (PDD), and calculated persistence to treatment as the difference in days between the first and last dispensation.Results: The authors enrolled 113 patients, 60 treated with adalimumab and 53 with etanercept. Adherence levels were 0.83 for adalimumab and 0.84 for etanercept. Switches occurred in 42% of adalimumab and in 47% of etanercept prescriptions.Conclusion: In the treatment of PsA, persistence and switches are a problem for patients who cannot follow a consistent therapy over time, for clinicians who have to manage therapy suspension and changes, and for the National Health System that must procure and pay for a high number of drugs without information on their real value in terms of efficacy and safety of use.

RESUMO

The aim of this study was to evaluate the cost-effectiveness of Anbainuo (ABN) plus methotrexate (MTX) (ABN + MTX) versus conventional disease-modifying anti-rheumatic drugs (cDMARDs) in rheumatoid arthritis (RA) patients.Forty-eight moderate to severe RA patients underwent ABN + MTX or cDMARDs treatment were consecutively enrolled and assigned to ABN + MTX group (n = 26) and control group (n = 22). Patients were followed up and their disease activity and quality of life (QoL) were evaluated at 3rd month, 6th month and 12th month after initiation of treatment. Treatment costs of 2 groups were calculated, then pharmacoeconomic analysis was performed.ABN + MTX increased drug cost and total cost while decreased indirect cost compared with cDMARDs after 12-month treatment. ABN + MTX group gained additional 0.22 quality-adjusted life years (QALY) and yielded an incremental cost-effectiveness ratio (ICER) of ¥104,293.6 per QALY after treatment. Sensitivity analysis reveals that rising ABN price by 20% produced an ICER of ¥130,403.6 per QALY, which was still lower than 3 times of the mean gross domestic product (GDP) per capita during the same period in China (¥165,960). Besides, ABN + MTX was more cost-effective in severe RA patients compared to moderate RA patients.ABN + MTX is cost-effective in treating moderate to severe RA patients compared with cDMARDs, although the total cost of ABN + MTX is relatively higher.

RESUMO

Introduction: Osteoarthritis (OA) is the leading cause of disability in the elderly, usually presenting with mono-or oligo-arthritis where local drug delivery by intra-articular (IA) injection may be more effective in terms of increased bioavailability, less systemic exposure and reduced adverse events. Several intra-articular medications for symptomatic are available on the market while the new disease-modifying drugs (DMOADs) are progressing into phase 3 pipeline of drug development.Areas covered: This narrative review covered the pharmacokinetic and pharmacodynamics of clinically available IA drugs which include corticosteroids, hyaluronic acid as well as injection techniques, efficacy, adverse effects and contraindications. In addition, the authors briefly describe the newer disease-modifying OA drugs (DMOAD) which are undergoing phase 3 pipeline of development such as Fibroblast growth factor (FGF-18) and Wnt inhibitor.Expert opinion: This is a rapidly evolving area with both new products and new trials regularly emerging. It is also a critically important area in a disease field that lacks for safe and effective treatments, where intra-articular delivery may enhance both local efficacy and reduce systemic toxicity.

RESUMO

Introduction: The treatment of psoriasis with conventional topical therapies and disease-modifying anti-rheumatic drugs (DMARDs) is often linked to unsatisfactory outcomes and the risk of serious adverse events. Over the last decades, research advances in understanding the role of tumor necrosis factor alpha (TNF α) and other cytokines in the pathogenesis of psoriasis have driven the introduction of biologic agents targeting specific immune mediators in everyday clinical practice. TNF α inhibitors are a consolidated treatment option for patients with moderate-to-severe disease with remarkable efficacy and a reassuring safety profile.Areas covered: The PubMed database was searched using combinations of the following keywords: psoriasis, TNF α inhibitors, biologic therapy, pharmacodynamics, adalimumab, etanercept, infliximab, certolizumab pegol, golimumab, adverse effects. The aim of this review is to describe the pharmacodynamic profile of anti-TNF α inhibitors, currently approved by the European Medicines Agency (EMA) for the treatment of psoriasis, focusing on related clinical implications, also in comparison to the new generation biological therapies targeting the interleukin 23/interleukin 17 axis.Expert opinion: Pharmacodynamics of TNF α inhibitors should be fully considered in planning patient's therapy strategies, especially in case of secondary failures, poor adherence to treatment, instable psoriasis, high risk of infection, pregnant or lactating women, metabolic comorbidities, coexistence of other immune-mediated inflammatory diseases.

RESUMO

BACKGROUND: Systemic sclerosis (SSc) is a clinically complex and challenging disease, the most frequent complication of which is interstitial lung disease, which leads to a worse prognosis. In this situation, cyclophosphamide is considered the criterion standard for treatment, despite the controversies regarding its efficacy and toxicity. However, studies using rituximab (RTX) have shown that this drug may be a promising therapeutic option. The objective is to describe a protocol of a systematic review (SR) that analyzes the scientific evidence on the effects of RTX on SSc. METHODS: This protocol is guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols. The databases to be searched are PubMed, Scopus, SciELO, LILACS, ScienceDirect, Web of Science, COCHRANE, WHOLIS, PAHO, and EMBASE. The studies that would be included in SR are clinical trials that evaluate the use of RTX in patients with SSc who meet the classification criteria for the disease according to American College of Rheumatology and European League Against Rheumatism (2013) and/or LeRoy criteria will be included in the SR. The data to be extracted are related to the characteristics of the studies: authors, year of publication, study location, type of study, sample size and age, patient characteristics, duration of intervention, therapeutic scheme, follow-up time, main variables, and main results. RESULTS: In our study, we hope to find articles presenting new evidence supporting treatment of SSc with RTX. CONCLUSIONS: The SR will present results of scientific evidence for the effects of RTX in SSc. We hope that the results could strengthen clinical decisions for the best treatment of SSc and guide future researches. PROSPERO REGISTRATION NUMBER: CRD42019132018.

RESUMO

Large-vessel vasculitis includes giant cell arteritis (GCA) and Takayasu arteritis (TA). GCA can affect persons from the age of 50 years and is more frequent among women. The disease course generally begins with an acute phase, with patients feeling very unwell and experiencing temporal headaches. Rapid diagnosis and treatment are necessary to reduce the risk of blindness. A suspected diagnosis must be confirmed by imaging, histology is optional. Initial treatment comprises oral prednisone. Recent studies have demonstrated inhibition of interleukin­6 with tocilizumab (TCZ) to be highly effective. Alternatively, methotrexate can be administered in a steroid-sparing approach. In contrast, TA onset is generally during childhood or adolescence, and begins with moderate systemic inflammation. The aorta and its main branches are affected. Treatment comprises steroids, disease-modifying antirheumatic drugs, and the tumor necrosis factor inhibitor infliximab or TCZ.

RESUMO

We report a 12-week-old boy presenting with incomplete refractory Kawasaki disease (KD) complicated with macrophage activation syndrome (MAS). The infant presented with cerebral irritability, pain, tachypnoea and vomiting for 10 days. He did not fulfil any of the classic diagnostic criteria for KD. Pericardial effusion on echocardiography in addition to severe dilatation of the coronary arteries in combination with leucocytosis and raised acute phase reactants led to the diagnosis of incomplete KD. Treatment with intravenous immunoglobulin and aspirin was initiated but without any response. The condition was subsequently refractory to additional treatment with infliximab and high-dose methylprednisolone. His condition worsened, fulfilling the criteria for MAS. High-dose anakinra was initiated, and remission of the inflammation was achieved.

RESUMO

Some patients have poor response to adult-onset Still disease (AOSD) traditional treatment, which easily recurs during the reduction of prednisone. We observed the efficacy and safety of tocilizumab combined with methotrexate (MTX) in the treatment of refractory AOSD, and to explore the possibility of reducing the dosage of tocilizumab after disease control.A total of 28 refractory AOSD cases who had an inadequate response to corticosteroids combined with at least 1 traditional immunosuppressive agent, and even large-dose prednisone could not relieve their conditions after recurrence, were selected in this study. They were treated with tocilizumab (intravenous 8 mg/kg) combined with MTX (oral 12.5 mg once a week). In detail, tocilizumab was firstly given every 4 weeks and after 6-month remission, it was then given every 8 weeks. Some items including body temperature, skin rash, joint swelling and pain, hepatosplenomegaly, blood routine, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), serum ferritin, and dosage of prednisone were observed before treatment as well as 2, 4, 8, 12, 24, 36, and 48 weeks after treatment. The adverse reactions occurring during the treatment were recorded.The body temperature was normal, the skin rash as well as joint swelling and pain disappeared, and laboratory indexes including CRP, ESR, white blood cell, neutrophilic granulocyte, platelet, hemoglobin, and ferritin were significantly improved after 8-week treatment (all P < .05). The clinical symptoms and laboratory indexes above mentioned were continuously improved 12, 24, 36, and 48 weeks after treatment. The mean dosage of prednisone was reduced from 71.4 ±â€Š20.7 mg/day to 55.0 ±â€Š11.1 mg/day after 2-week treatment, and to 3.3 ±â€Š2.1 mg/day after 48-week treatment (all P < .05). Prednisone was discontinued in 5 cases after 36-week treatment and in 7 cases after 48-week treatment. No serious adverse reactions occurred during the treatment.Tocilizumab can rapidly and markedly improve the clinical symptoms and laboratory indexes and contribute to reduction and discontinuation of prednisone in refractory AOSD. The patients' conditions are stable after reduction or discontinuation of prednisone and the tocilizumab possesses good safety.

RESUMO

BACKGROUND: Subcutaneous methotrexate (sMTX) administration is considered more effective than the oral route due to better bioavailability and a lower rate of adverse drug reactions (ADRs); however, clinical data supporting this hypothesis is scarce. OBJECTIVES: The aim of the study was to evaluate the efficacy and tolerability of sMTX in patients with active rheumatoid arthritis (RA), including a subset classified as an early stage of RA. MATERIAL AND METHODS: A post-marketing, multicenter, open-label, non-randomized, non-interventional study enrolled 771 adult patients with active RA treated with sMTX (Metex®) for 2-6 weeks. The evaluation of therapy effectiveness (DAS28-ESR or DAS28-CRP) and monitoring of ADRs was an element of routine patient management. Therapy effectiveness was scored as the achievement of remission or response (according to European League Against Rheumatism (EULAR)). RESULTS: Among 761 (98.7%) patients that continued sMTX (after 25-31 weeks), clinical response was achieved by 69.5%, remission by 19.2% and low disease activity by 34.2%. Patients aged >60 years were less likely to achieve both remission (odds ratio (OR) = 0.61 (95% confidence interval (95% CI) = 0.39-0.93)) and clinical response (OR = 0.82 (95% CI = 0.71-0.95)), while overweight/obese patients (OR = 1.11 (95% CI = 1.00-1.24)) and those with early RA had greater chance to reach a clinical response (OR = 1.18 (95% CI = 1.03-1.34)). There were 16 ADRs (no serious or severe). In addition, at least 2-fold increase in alanine transaminase (ALT) activity was noted in 10 patients (1.3%). CONCLUSIONS: After 6-month therapy with sMTX, about 70% of patients with RA achieve a clinical response, and remission was observed in 20%. Younger age, overweight/obesity and an early stage of the disease are factors increasing therapy effectiveness; sMTX is well tolerated.

RESUMO

Objective: The effects of a dose-reduction intervention of biological disease-modifying anti-rheumatic drugs (bDMARDs) in patients in remission were analysed with epidemiology and health economics strategies. The aims were to analyse changes in bDMARD dosage, evaluate potential disease worsening, and estimate cost reduction. Method: This uncontrolled single-centre observational study analysed bDMARD-treated patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and spondyloarthritis (SpA). bDMARD expenditure constituted a proxy for bDMARD doses, which enabled group-level analysis. Interrupted time-series regression was used to analyse changes in treatment cost due to the dose reduction. Disease activity and treatment durations were monitored to investigate disease worsening. Results: In total, 997 biological treatment cases were analysed. This involved 527 bDMARD patients, where an unknown fraction of patients was given reduced doses. Disease activity of RA and PsA patients decreased from 2001 to 2009 and remained stable after that, while disease activity for SpA patients was unchanged, indicating no disease worsening from the intervention. The dose tapering resulted in decreased bDMARD expenditure, indicating a decrease in bDMARD consumption, which led to an accumulated cost reduction of 4 178 000 EUR. Conclusions: The results suggest that dose reduction can be safely performed in patients in treatment remission on a group level without compromising treatment efficacy. Subcutaneous bDMARDs, including abatacept, adalimumab, and etanercept, were observed to be well suited to customizing dosage. This study highlights the potential for individualized and personalized rheumatic medicine by providing dose reduction to individual patients, while monitoring disease activity.

RESUMO

BACKGROUND: Methotrexate (MTX) is still the first-choice drug for the treatment of rheumatoid arthritis (RA). In Japan, MTX doses of up to 16 mg/week were approved in 2011. In this study, we aimed to identify the gene polymorphisms that can predict therapeutic effects of MTX in Japanese patients in current clinical settings. METHODS: This study involved 171 patients with RA (all Japanese nationals, age 63.5±10.0 years) who had been administered MTX. The analyzed polymorphisms included 82 single nucleotide polymorphisms (SNPs) involved in the MTX pharmacological pathway or in the pathogenesis of RA. Responders were patients who showed high sustained remission or low disease activity with MTX or conventional disease-modifying anti-rheumatic drugs (DMARDs) treatment beyond 6 months. Non-responders were patients who showed moderate or high disease activity, who were prescribed biological DMARDs. A logistic model was constructed with Responder/Non-responder as the target variable, and minor allele frequency was set as an explanatory variable. RESULTS: None of the 82 SNPs targeted for analysis met the Bonferroni significance threshold of 6.098×10-4. However, we identified SLCO1B1 rs11045879 as an SNP that might yield significant results if the number of patients were to be increased (P=0.015). CONCLUSIONS: The rs11045879 minor allele in the SLCO1B1 gene is a potential predictor of non-responders to MTX treatment among Japanese RA patients. In future collaborative research, we will investigate whether the association with SLCO1B1 polymorphism is significant by performing statistical analysis with a larger study population.

RESUMO

BACKGROUND: Diagnosis and management of acute abdomen secondary to systematic lupus erythematosus (SLE) has always been a clinical challenge. CASE PRESENTATION: A 21-year-old lady, with BMI 17.7, presented to our department with acute abdomen. Laparoscopy was carried out to exclude surgical emergency when conservative regimen failed. The patient revealed a history of purpuric changes and lupus test was positive for SLE. CONCLUSION: Based on our experience, early laparoscopy to alleviate acute abdomen has shown to improve the prognosis of the patient.

RESUMO

Introduction: Early biological treatment of rheumatoid arthritis (RA) may reverse the autoimmune response in some patients resulting in favorable long-term outcomes. Although the cost-effectiveness of this strategy has been questioned, biosimilar entries warrant the revision of clinical and pharmaco-economic evidence. Areas covered: We conducted a systematic review of randomized controlled trials (RCTs) published up to 24 May 2018 in Pubmed, EMBASE and Cochrane CENTRAL, comparing infliximab with non-biological therapy in patients with RA naïve to methotrexate. We performed meta-analyses for efficacy outcomes at month 6 and years 1 and 2. Six RCTs were identified, involving 1832 patients. At month 6 ACR70 response and remission, and at year 1 ACR20/ACR70 responses and remission were improved significantly with first-line infliximab versus control. The differences were not significant at year 2. We reviewed cost-utility studies, up to 31 October 2018 in PubMed, Cochrane CENTRAL and the CRD HTA databases. Four studies indicated that first-line use of originator infliximab calculated at 2005-2008 prices was not cost-effective. Expert opinion: We demonstrated the efficacy benefits of first-line infliximab therapy up to 1 year in methotrexate-naïve RA. We highlighted the need for standardized reporting of outcomes and conducting cost-effectiveness analyses of first-line biosimilar therapy in RA.

RESUMO

Methotrexate (MTX) was originally formulated as one of the first antitumour drugs due to its ability to alter folate metabolism, which renders it to be an antiproliferative agent. Classically, the higher dosage is administered via parenteral route, in a cyclical fashion, to achieve antitumour effects. Patients on high doses of MTX are prone to develop rare complications of myelosuppression and pancytopenia, in a dose-dependent fashion, secondary to altered folate metabolism. 1 Herein, we present a unique case of rheumatoid arthritis presented with pancytopenia due to low-dose MTX and doxycycline drug interaction. We also report the successful management of pancytopenia and oral ulcers with combination therapy of leucovorin and granulocyte colony-stimulating factor.

RESUMO

OBJECTIVES: The MARI study investigated the prescription patterns of methotrexate (MTX) in patients presenting with rheumatoid arthritis (RA) in Italy. The primary aims of this cross-sectional analysis from the MARI study were to investigate the effect of gender on the prescription patterns and safety of MTX therapy. METHODS: The study enrolled 1336 patients with RA. Retrospective data included patients' clinical history, previous treatment with MTX and other DMARDs, and MTX modifications in the previous 12-month period. Cross-sectional data included information about current treatment with MTX (dose and route of administration, and adverse events), concomitant medications, disease activity, and modifications of MTX treatment at study entry. The prescription patterns of MTX, rates and causes of MTX modifications were analysed according to gender. RESULTS: There were no significant differences related to gender in the prescription patterns of MTX, either at 6 months after starting MTX or at the time of study entry. In the 12 months prior to study entry, women (4%) were more likely to undergo MTX modifications (dose or route of administration) compared to men (2%, p=0.032), due to subjective intolerance, but this difference was no longer significant after controlling for confounders. At study entry, a higher proportion of women (27%) reported tolerability issues (nausea and weakness) related to MTX compared to men (14%, p=0.001). Although a similar percentage of males and females changed dose or route of administration of MTX at the time of study entry, the reasons for such modifications were dissimilar between genders. Particularly, a higher proportion of women underwent MTX modification due to intolerance (women 6% vs. men 1%, p=0.002). CONCLUSIONS: In Italy, prescription patterns of MTX do not differ between genders. However, women seem to be at higher risk of adverse events leading to MTX modifications.

RESUMO

Objectives: Treatment of juvenile idiopathic arthritis has changed rapidly since the introduction of various biologics almost twenty years ago. Many clinical trials have been performed to monitor efficacy and safety of new agents. The aim of this review is to summarize safety concerns, which were observed during prospective clinical trials. Methods: Since etanercept was the first biologic approved and remains the most frequently used, as first biologic in polyarticular JIA patients, the authors calculated the relative risk of the adverse events for all examined biologicals and compared the values with the value of etanercept. Results: Relative rates for all adverse events showed similar rates for etanercept, infliximab, golimumab, and tocilizumab, whereas adalimumab showed higher rates and abatacept lower rates. Comparison of rates for serious adverse events demonstrated, that rates seemed comparable for etanercept, adalimumab, infliximab, and tocilizumab. Again, abatacept showed a lower rate, whereas golimumab seems to have a higher relative risk for serious adverse events. Rate of infection was lowest in patients treated with abatacept or tocilizumab, patients treated with etanercept, adalimumab and Infliximab again had similar rates. Conclusion: The safety profiles of actually approved biologics are highly acceptable. However, further observation, especially long-term observation through registry studies, is required.

RESUMO

PURPOSE: This investigation was aimed to explore the targeting potential of folate conjugated double liposomes (fDLs) bearing combination of synergistic drugs (Prednisolone and Methotrexate) for effective management of the rheumatoid arthritis (RA). METHODS: To overcome the drawbacks of monotherapy, a combination of prednisolone (PRD) (an anti-inflammatory agent) and methotrexate (MTX) (a disease modifying anti-rheumatoid agent, DMARDs) was chosen for dual targeting approach. fDLs were prepared in two steps i.e. development of inner liposomes (ILs) using thin film casting method followed by encapsulation of ILs within folate conjugated outer liposomes (double liposomes; fDLs). Developed liposomes were characterized for various physicochemical parameters and in vivo performance. RESULTS: fDLs were prepared using FA-PEG-4000-NH-DSPE conjugate. These double liposomes were having 429.3 ± 3.6 nm in size with 0.109 PDI, 8.01 ± 0.3 mV zeta potential (ζ) and 66.7 ± 3.9% and 45.3 ± 1.7% entrapments of PRD and MTX, respectively. After 24 h, the concentrations of PRD in blood were observed to be 8.66 ± 3.11 (ILs) and 15.13 ± 0.81% (DLs) while concentration of MTX were found to be 10.89 ± 0.69 and 2.34 ± 3.15% when given as ILs and fDLs, respectively. The concentration of both drugs in inflamed joint was observed to be higher than that in the non-inflamed joints. CONCLUSIONS: The folate conjugated double liposomes possess superior targeting efficiency than conjugated and unconjugated single liposomes.
