33559176 Stratification of methotrexate-induced oral ulcers in rheumatoid arthritis patients. 2021 May AIM: There is a deficiency in the data concerning the clinical forms of methotrexate-induced oral ulcers. This study was conducted to stratify clinical forms of methotrexate-induced oral ulcers in rheumatoid arthritis patients. METHODS: This study included rheumatoid arthritis patients receiving methotrexate as monotherapy. All eligible patients were subjected to thorough clinical examination and full history to identify oral events. Drug history, dose, and duration of MTX were recorded. RESULTS: Among 794 rheumatoid arthritis patients, mean methotrexate dose and duration were 14.3 mg/week and 5.2 years, respectively. Oral ulcers were detected in 6.2% of the patients and 30% of the patients reported previous oral ulcers. Among the detected oral ulcers, 44.9% manifested as deep irregular ulcers, 30.6% presented as aphthous-like ulcers, 14.3% were diffuse mucositis, and 10.2% appeared as lichenoid reaction. CONCLUSION: Methotrexate-induced oral ulceration could be localized or generalized. Localized forms were more noticed than generalized forms. Higher doses and longer durations of methotrexate were detected among patients with generalized oral ulcers.
34622769 Comparative efficacy and safety of etanercept biosimilars in comparison with etanercept in 2021 Dec OBJECTIVE: We aimed to assess the relative efficacy and safety of etanercept biosimilars and etanercept originators in patients with active rheumatoid arthritis (RA) who showed an inadequate response to methotrexate (MTX). MATERIALS AND METHODS: We performed a Bayesian network meta-analysis to combine direct and indirect evidence from randomized controlled trials (RCTs) examining the efficacy and safety of etanercept biosimilars vs. etanercept originators in patients with active RA despite treatment with MTX. RESULTS: Three RCTs involving 1,200 patients, including 4 types of biologics, were included. Ranking probability based on the surface under the cumulative ranking curve (SUCRA) indicated that LBEC0101 had a high probability of being the better treatment in terms of the American College of Rheumatology 20 (ACR20) response rate (SUCRA = 0.744), followed by HD203 (SUCRA = 0.457), SB4 (SUCRA = 0.446), and etanercept (SUCRA = 0.352), although no difference in the ACR20 response rate between the biosimilars and etanercept groups was found. Although not statistically significant, there was a difference in the ranking probability of safety based on serious adverse events (SAEs) among interventions. Ranking probability based on SUCRA values indicated that LBEC0101 had the highest probability of being the safest treatment (SUCRA = 0.638), followed by SB4 (SUCRA = 0.495) and HD203 (SUCRA = 0.475), while etanercept had the lowest probability of being the safest treatment (SUCRA = 0.393). CONCLUSION: No significant difference was found between etanercept biosimilars and etanercept originators in patients with active RA despite treatment with MTX in terms of the ACR20 response rate and SAEs.
32159414 Clinical aspects in patients with rheumatoid arthritis complicated with lymphoproliferativ 2021 Jan OBJECTIVES: To identify predictive factors for lymphoproliferative disorders (LPDs) that persist after methotrexate (MTX) withdrawal (Persistent-LPD) and the optimal treatment for rheumatoid arthritis (RA) after LPD regression. METHODS: Among 3666 patients with RA treated with MTX in our department from 2006 to 2017, 26 cases of LPD that regressed after MTX withdrawal (Regressive-LPD) and 25 cases of Persistent-LPD were compared. Multivariate logistic analysis was performed to identify predictive factors for Persistent-LPD. Retention rates of biological disease-modifying antirheumatic drugs (bDMARDs) were calculated using the Kaplan-Meier Method. RESULTS: In Persistent-LPD, the incidence of diffuse large B-cell lymphoma was higher (76%). The overall 2-year survival rate was 83.9%: 95.8% for Regressive-LPD and 71.0% for Persistent-LPD. The International Prognostic Index (IPI) risk classification was useful for predicting Persistent-LPD. bDMARDs were introduced in 38 RA patients after LPD regression. Unadjusted retention rate of bDMARDs in the 51 LPD patients was significantly lower than that in the 1668 non-LPD RA patients in our bDMARD cohort (controls) (p = 0.029). The 1-year retention rates for bDMARDs were 69% and 64% for tocilizumab and abatacept, respectively vs. 46% for TNF-inhibitor (TNFi). CONCLUSION: Risk assessment using IPI predicted Persistent-LPD. After LPD regression, non-TNFi tended to have higher retention rates.
33877648 Disease-Modifying Antirheumatic Drugs (DMARDs) and drug interactions in dentistry. 2021 Apr OBJECTIVE: Rheumatoid arthritis is a chronic autoimmune disease. Treatment aims to reduce and improve its signs and symptoms. Hence, Disease-Modifying Antirheumatic Drugs (DMARDs) are the treatment of choice. The objective of this study was to identify potential interactions between DMARDs and the drugs most frequently prescribed in dentistry in order to avoid adverse reactions. MATERIALS AND METHODS: This literature review sets out to define possible adverse reactions provoked by pharmacological interactions between DMARDs and the drugs commonly prescribed in dentistry. A search was conducted in PubMed by searching the names of drugs used in dentistry, "drug interactions," "rheumatoid arthritis," and "dentistry", "hydroxychloroquine", "leflunomide", "methotrexate", "sulfasalazine", "adalimumab", "anakinra", "etanercept", "abatacept", "infliximab" and "rituximab". RESULTS: It was found that most DMARDs show potential interactions with many drugs used in dentistry, including various antibiotics, analgesics, anesthetics, antifungals, and corticosteroids. CONCLUSIONS: It is clinically important for oral health clinicians to be aware of possible drug interactions between DMARDs and the drugs commonly prescribed in dentistry to prevent potential adverse reactions and avoid endangering the patient.
33950231 Clinical use of Jak 1 inhibitors for rheumatoid arthritis. 2021 May 5 The uptake of Jak inhibitors in the RA space has been among the most rapid in rheumatology, based on the results of comprehensive clinical trial programmes of five agents. Newer generations of Jak inhibitors, like upadacitinib and filgotinib, target Jak 1 selectively with the aim of maximizing efficacy and to improve safety. This article will review the clinical significance of evidence on: (i) Jak 1 selectivity; (ii) efficacy from the SELECT and FINCH clinical trial programmes including patient intolerant or inadequately responding to MTX (MTX-IR) and other csDMARDs patients who are bDMARD-IR) and those using monotherapy when MTX is not tolerated or contraindicated and those treated when methotrexate naive; and (iii) safety from the clinical trial programmes of these two agents will be discussed.
33887489 Efficacy and safety of abatacept in interstitial lung disease of rheumatoid arthritis: A s 2021 Jun BACKGROUND: Interstitial lung disease (ILD) is a serious complication that represents the second leading cause of death in patients with rheumatoid arthritis (RA). Treatment of RA-ILD remains controversial. The absence of randomized clinical trials and specific ACR or EULAR therapeutic guidelines makes it difficult to establish solid therapeutic recommendations on this issue. In this scenario, real-world data is especially valuable. OBJECTIVE: To review the literature evidence on the efficacy and safety of abatacept (ABA) for the treatment of rheumatoid arthritis (RA) with associated interstitial lung disease (ILD), given its clinical relevance and the lack of consensus on its therapeutic management. METHODS: PUBMED and EMBASE were searched from the date of approval of ABA to the end of 2020 using a combination of RA, ILD and ABA terms following PRISMA guidelines. Identified studies were evaluated by two independent investigators. RESULTS: Nine original studies (1 case series and 8 observational studies) were selected for inclusion in the systematic review. No randomized trial or meta-analysis were identified. The mean age of patients ranged from 61.2 to 75 years and the mean RA duration varied from 7.4 to 18 years. Subcutaneous ABA (74.5%-91%) predominated in combination with conventional synthetic DMARDs (csDMARDs) (58%-75%), and it was used as first-line biologic agent in 22.8%-64.9% of the patients. The mean course of ILD ranged from 1 to 6.7 years, being usual and nonspecific interstitial pneumonia the most frequent patterns. Improvement or stabilization of ILD imaging (76.6%-92.7%) and FVC or DLCO (>85%) was described after a mean follow-up of 17.4-47.8 months, regardless of the pattern of lung involvement, being more remarkable in patients with shorter evolution of ILD. ABA led to significantly lower ILD worsening rates than TNF inhibitors (TNFi) and was associated with a 90% reduction in the relative risk of deterioration of ILD at 24 months of follow-up compared to TNFi and csDMARDs. Combination with methotrexate may have a corticoid-sparing effect. No unexpected adverse events were identified. CONCLUSIONS: Current evidence suggests that ABA may be a plausible alternative to treat RA patients with ILD. It would be highly desirable to develop prospective randomized controlled studies to confirm these findings.
32436170 Rheumatoid Nodule Simulating a Parotid Tumor. 2021 Mar Rheumatoid nodules are an extra-articular manifestation of rheumatoid arthritis that are rarely found in the maxillofacial region. A 59-year-old woman with rheumatoid arthritis treated with methotrexate, leflunomide, and tocilizumab, presented with an enlarging mass in the left parotid region. Magnetic resonance imaging (MRI) displayed a lesion compatible with a neoplasm. However, an incisional biopsy showed features consistent with a rheumatoid nodule. The patient was managed conservatively, including cessation of methotrexate and initiation of treatment with hydroxychloroquine. At 15-month follow-up, the lesion had a significant reduction in size. To our knowledge, this is the first case report of a rheumatoid nodule in the parotid region. Although it is a rare manifestation, clinicians should consider this a possible differential diagnosis of parotid masses in patients with a history of rheumatoid arthritis or connective tissue disease.
33938795 Risk of liver fibrosis induced by methotrexate and other rheumatoid arthritis medications 2022 Jan OBJECTIVES: We aimed to estimate the amount of scarring in the liver with the fibrosis-4 (FIB-4) index in patients with rheumatoid arthritis (RA) with special interest in methotrexate (MTX) influence. METHODS: This was a cross-sectional monocentric study including successive RA patients recruited for a 12-month period. Data on liver function, disease activity, hepatotoxic and cardiovascular risk factors were systematically collected. The FIB-4 index was calculated according the following formula: (age(years)× AST(U/L)/platelet (PLT) (109/L)×√ALT(U/L)). RESULTS: We included 170 patients with established RA: 141 (83%) were women with a mean age of 59±12 years and mean disease duration of 15±11 years. The FIB-4 was low and not significantly different between patients receiving MTX (n=102), patients previously treated with MTX (n=39) and patients never treated with MTX (n=29). No correlation was observed between FIB-4 values and cumulative MTX dose (r=0.09, p=0.271). No relationship was observed between FIB-4 and MTX treatment duration. The FIB-4 index was found significantly increased in patients receiving leflunomide (n=24), (median (range) 1.58 (0.46-3.16) vs. 1.18 (0.54-3.40), p=0.019) and tocilizumab (n=14), (median (range) 1.82 (0.75-3.73) vs. 1.18 (0.54-3.40), p=0.005) compared to patients not receiving DMARDs (n=29). Multivariate logistic regression analyses revealed an independent association between increased FIB-4 (>1.45) and male gender, low disease activity, and treatment with leflunomide and tocilizumab. CONCLUSIONS: RA patients with long-term maintenance MTX therapy have low FIB-4 values suggesting that MTX is not associated with an increased risk of advanced liver fibrosis. Increased FIB-4 values have been detected in leflunomide- and tocilizumab-treated patients, which will deserve dedicated further investigations.
34756311 Systematic review of the impact of drugs on diffuse interstitial lung disease associated w 2021 Nov OBJECTIVE: To review the available evidence on the impact of rheumatoid arthritis (RA) treatments in associated diffuse interstitial lung disease (ILD). METHODS: Systematic review of studies evaluating the impact of pharmacological treatment in patients with RA and ILD. A bibliographic search in MEDLINE, EMBASE and Cochrane, a selection of articles and the methodological quality assessment (FLC 3.0 OSTEBA) and grading of the level of evidence (SING) of the selected articles were performed. RESULTS: 1,720 references were identified in primary search and 7 in manual or indirect. Forty-three articles were included: 7 systematic reviews, 2 randomized clinical trials, 5 cohort studies, 8 case-control studies and 21 case series. Methotrexate (MTX) and leflunomide (LEF) do not increase incidence, complications or mortality due to ILD. Although the results are not uniform, anti-TNF have often had worse outcomes in incidence, progression and mortality due to ILD than MTX, LEF, abatacept (ABA) and rituximab (RTX). The evidence found is scarce for JAK kinase and antifibrotic inhibitors, and controversial for IL-6 inhibitors. CONCLUSIONS: There is no evidence that MTX or LEF worsens the prognosis of patients with AR-EPID. RTX and ABA seem to have better results than other biologicals, such us TNFi, often achieving stabilization and, in some cases, the improvement of ILD in patients with RA.
34263700 Pretreatment resistin levels are associated with erosive disease in early rheumatoid arthr 2022 May OBJECTIVE: Resistin is an adipocytokine related to insulin resistance and inflammation. We investigated whether resistin is associated with disease activity and inflammation in disease-modifying anti-rheumatic drug (DMARD)-naïve rheumatoid arthritis (RA) patients, whether it has predictive value for radiological disease progression, and whether tumour necrosis factor-α (TNF-α) is involved in these effects. METHOD: Ninety-nine patients with early, DMARD-naïve RA participated in the NEO-RACo study. Patients were treated for the first 4 weeks with a combination of methotrexate, sulfasalazine, hydroxychloroquine, and prednisolone (FIN-RACo treatment). Thereafter, they were randomized to receive either infliximab or placebo added to the combination for 6 months. Patients were followed for 5 years. Disease activity was evaluated using the Disease Activity Score based on 28-joint count-erythrocyte sedimentation rate, radiographs were scored with the modified Sharp-van der Heijde method, and plasma resistin concentrations were measured by immunoassay. Human THP-1 macrophages were used in the in vitro studies. RESULTS: A high resistin level at baseline was associated with active inflammatory disease and predicted more rapid radiological progression during 5 year follow-up. Adding infliximab to the DMARD combination delayed radiological progression and overcame the poor predictive value of resistin. Resistin increased TNF-α production in human macrophages, indicating a possible connection between resistin and TNF-α. CONCLUSION: The results suggest that high resistin concentration may be a useful marker to distinguish patients with an increased risk of erosive disease in early active RA, and that adding TNF-α antagonist to the traditional DMARD combination may delay radiological progression of the disease in these patients. The study has been registered at https://www.clinicaltrials.gov(NCT00908089).
34805398 Clinical Efficacy of Methotrexate Combined with Iguratimod on Patients with Rheumatoid Art 2021 OBJECTIVE: This study was designed to explore the clinical efficacy of methotrexate combined with iguratimod on patients with rheumatoid arthritis (RA) and its influence on the expression levels of HOTAIR in serum. METHODS: A total of 268 RA patients were selected as research objects, 145 patients received methotrexate alone were used as a control group (CG), 123 patients received methotrexate combined with iguratimod were taken as a research group (RG), and serum of 60 healthy people undergoing physical examination was selected as a healthy control group (HCG). The therapeutic value of two therapeutic methods for RA was compared, and the HOTAIR expression in serum was detected by qRT-PCR. RESULTS: Compared with methotrexate used alone, the joint use of methotrexate and iguratimod could provide better clinical efficacy for RA patients and would not increase the incidence of adverse events. HOTAIR was highly expressed in the serum of RA patients, and its expression decreased after treatment. CONCLUSION: Combination therapy of methotrexate and iguratimod is a safe and effective way to treat RA patients, which can be popularized clinically.
33607787 Methotrexate can prevent cardiovascular events in patients with rheumatoid arthritis: An u 2021 Feb 19 AIMS: The incidence of cardiovascular events (CVEs) in patients with rheumatoid arthritis (RA) is higher than that in people without RA. This may be because inflammation promotes the progression of atherosclerosis. Anti-inflammatory drugs might reduce the occurrence of CVEs in patients with RA. Methotrexate (MTX) is a conventional synthetic anti-rheumatic drug that is widely used in the treatment of RA. We performed a meta-analysis to determine whether MTX can prevent CVEs in RA patients. Then, we discussed the possibility of using MTX to prevent recurred CVEs in patients with coronary heart disease (CHD). METHODS: We searched PubMed, Embase, Web of Science, and the Cochrane Library using the key words "methotrexate," "cardiovascular," "acute coronary syndrome," "coronary heart disease," "myocardial infarction," "angina pectoris," and "rheumatoid arthritis." The efficacy outcome was defined as a composite of CVEs, including stable angina, acute coronary syndrome, stroke, heart failure, and cardiac death. RESULTS: A total of 10 studies and 195,416 RA patients were included in our meta-analysis, and the effect size of relative risk (RR) was pooled using a fixed effect model. The results showed that MTX prevented CVEs in RA patients (RR: 0.798, 95% CI 0.726-0.876, P = .001, I2 = 27. 9%). CONCLUSION: MTX can prevent CVEs in RA patients, but there is not sufficient evidence for using MTX to treat patients with CHD.
35153040 Clinical management and discontinuation of treatment in patients with recent onset rheumat 2022 Feb INTRODUCTION: The treatment of Rheumatoid Arthritis (RA) has changed dramatically in recent years, especially with the use of disease modifying drugs (DMARDs). Data on the management of this disease in clinical trials are abundant, but not so in real life. The aim of our study is to describe the management of an early RA cohort in daily clinical practice, especially DMARD discontinuations and reasons. METHODS: A retrospective observational study of patients with RA diagnosed between 01/07 and 12/14 followed up to 01/17, using >1 DMARD ≥ 3 months. VARIABLES: sociodemographic, clinical, treatment, DMARD discontinuation and reason. Descriptive analysis of sociodemographic, clinical and treatment characteristics. Discontinuation incidence rate (DIR) due to survival techniques, expressed in 100 patients*year with 95% confidence interval. RESULTS: 814 patients were included with 2388 courses of treatment, 77% women, mean age 57.5 years. First course: monotherapy (92.75%), especially Methotrexate (56.06%). In later courses there was increased combined therapy and use of biologicals (mainly Etanercept). There were 1094 discontinuations (29.5 [27.8-31.3]). The DIR was higher for adverse events (15.9 [14.7-17.3]), biologicals (49.6 [43.1-57.2]) and combined therapy. The DMAR with the lowest DIR was MTX (25.8 [23.8-28.1]). CONCLUSION: Methotrexate was the most used drug, biologicals increased throughout the follow-up, the most frequent being Etanercept. The DMARD DIR was 29*100 patients per year, mainly due to adverse events. It seems to be higher in the therapies that include biologicals and combined therapies. MTX is the drug with the lowest DIR.
34732237 Observation of the curative effect of Guizhi-Shaoyao-Zhimu decoction combined with methotr 2021 Nov 3 BACKGROUND: Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease with the primary clinical symptoms of joint swelling and pain. Early detection of erosion and synovial inflammation at an active stage resulting from RA can prevent damage to the joints and activity restriction. However, there are still many patients who do not respond to these treatments; the development of newer, safer drugs is urgently needed. Compared to Western medicine, Guizhi-Shaoyao-Zhimu decoction has equal or higher efficacy and safety for RA patients. With the widespread use of musculoskeletal ultrasound (MSUS), this technology holds great value for the degree of joint damage in RA patients, guiding the clinical selection of treatments, and assessing of prognosis. Therefore, we designed a double-blinded randomized controlled clinical trial to measure the safety and efficacy of Guizhi-Shaoyao-Zhimu decoction in treating early-stage RA using MSUS. METHODS: This study is a randomized, double-blinded, parallel group, placebo-controlled trial. A total of 152 adult participants with early RA will be enrolled, with balanced treatment allocation (1:1). The experimental intervention will be Guizhi-Shaoyao-Zhimu decoction plus the conventional medicine methotrexate and the control intervention will be placebo plus the conventional drug methotrexate for 3 months. In addition, both groups will receive folic acid during treatment to prevent side effects from methotrexate. The primary outcomes are the erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), hepatic and renal function, visual analog scale, disease activity score in 28 joints, measurement scale for TCM symptoms, and 7-joint ultrasound score. DISCUSSION: We designed this double-blinded randomized controlled clinical trial to evaluate the efficacy and safety of Guizhi-Shaoyao-Zhimu decoction in RA patients using MSUS. The results of this trial may provide insights into how to improve the clinical symptoms of RA patients and delay further joint destruction. We hope that this trial may provide preliminary evidence of the efficacy of Guizhi-Shaoyao-Zhimu decoction in treating RA patients and that these results aid researchers, practitioners, and patients alike. AIM: The main aim of the study is to clarify the efficacy and safety of Guizhi-Shaoyao-Zhimu decoction in patients with early RA.

34417705 The role of renin angiotensin system in the pathophysiology of rheumatoid arthritis. 2021 Sep BACKGROUND: In rheumatoid arthritis (RA) and osteoarthritis (OA), chronic inflammatory processes lead to progresive joint destruction. The renin-angiotensin system (RAS) is involved in the pathogenesis of RA and OA. The aim of this mini-review article is to summarize evidence on the role of RAS in RA and OA. METHODS: A non-systematic search in Pubmed included terms as "rheumatoid arthritis", "renin angiotensin system", "osteopenia", "RANKL", "DKK-1", "MMP", "inflammation", "angiogenesis", "local renin-angiotensin system", "angiotensin converting enzyme", "AT2 receptor", "Ang-(1-7)", "VEGF", "angiotensine receptor blocker", "angiotensin converting enzyme inhibitors", "renin inhibitors". RESULTS: Both RAS axes, the classical one, formed by angiotensin converting enzyme (ACE), angiotensin (Ang) II and AT1 receptor (AT1R) and the counter-regulatory one, composed by ACE2, Ang-(1-7) and the Mas receptor, modulate inflammation and tissue damage. Ang II activates pro-inflammatory mediators and oxidative stress. Conversely, Ang-(1-7) exerts anti-inflammatory actions, decreasing cytokine release, leukocyte attraction, density of vessels, tissue damage and fibrosis. Angiogenesis facilitates inflammatory cells invasion, while osteopenia causes joint dysfunction. Up-regulated osteoclastogenisis and down-regulated osteoblastogeneses were associaed with the activation of the classical RAS axis. Three different pathways, RANKL, DKK-1 and MMPs are enhanced by classical RAS activation. The treatment of RA included methotrexate and corticosteroids, which can cause side effects. Studies with angiotensin receptor blockers (ARBs), angiotensin converting enzyme inhibitors (ACEi) and renin inhibitors have been conducted in experimental and clinical RA with promising results. CONCLUSION: The classical RAS activation is an important mechanism in RA pathogenesis and the benefit of ARB and ACEi administration should be further investigated.
33251808 Perspectives of Methotrexate-Based Radioagents for Application in Nuclear Medicine. 2021 Jan 4 Methotrexate is a gold standard among disease modifying antirheumatic drugs and is also extensively used clinically in combination with oncological therapies. Thus, it is not surprising that nuclear medicine found an interest in methotrexate in the search for diagnostic and therapeutic solutions. Numerous folate-related radiopharmaceuticals have been proposed for nuclear medicine purposes; however, methotrexate radioagents represent only a minority. This imbalance results from the fact that methotrexate has significantly weaker affinity for folate receptors than folic acid. Nevertheless, radiolabeled methotrexate agents utilized as a tool for early detection and imaging of inflammation in rheumatoid arthritis patients gave promising results. Similarly, the use of multimodal MTX-release nanosystems may find potential applications in radiosynovectomy and theranostic approaches in folate receptor positive cancers.
34019595 Associations of ultrasound-based inflammation patterns with peripheral innate lymphoid cel 2021 OBJECTIVES: We aimed to explore the associations of musculoskeletal inflammation patterns with peripheral blood innate lymphoid cell (ILC) populations, serum cytokines/chemokines, and treatment response to methotrexate in patients with rheumatoid arthritis (RA) and spondyloarthritis (SpA). METHODS: We enrolled 100 patients with either RA or SpA and performed ultrasound to evaluate power Doppler signals for synovitis (52 joint regions), tenosynovitis (20 tendons), and enthesitis (44 sites). We performed clustering analysis using unsupervised random forest based on the multi-axis ultrasound information and classified the patients into groups. We identified and counted ILC1-3 populations in the peripheral blood by flow cytometry and also measured the serum levels of 20 cytokines/chemokines. We also determined ACR20 response at 3 months in 38 patients who began treatment with methotrexate after study assessment. RESULTS: Synovitis was more prevalent and severe in RA than in SpA, whereas tenosynovitis and enthesitis were comparable between RA and SpA. Patients were classified into two groups which represented synovitis-dominant and synovitis-nondominant inflammation patterns. While peripheral ILC counts were not significantly different between RA and SpA, they were significantly higher in the synovitis-nondominant group than in the synovitis-dominant group (ILC1-3: p = 0.0007, p = 0.0061, and p = 0.0002, respectively). On the other hand, clustering of patients based on serum cytokines/chemokines did not clearly correspond either to clinical diagnoses or to synovitis-dominant/nondominant patterns. The synovitis-dominant pattern was the most significant factor that predicted clinical response to methotrexate (p = 0.0065). CONCLUSIONS: Musculoskeletal inflammation patterns determined by ultrasound are associated with peripheral ILC counts and could predict treatment response to methotrexate.
32681975 Pop a pill or give myself a shot? Patient perspectives of disease-modifying anti-rheumatic 2021 Jan OBJECTIVE: To assess how patients with rheumatoid arthritis (RA) decide whether to add oral disease-modifying anti-rheumatic drugs (DMARDs) versus injectable biologic DMARDs when methotrexate response is inadequate. METHODS: Using nominal group technique (NGT), RA patients answered the question "What sort of things are important to you when you make a decision between adding pills versus injectable medications to treat rheumatoid arthritis when methotrexate fails to control RA disease activity?" Patients nominated, discussed, and voted for the responses. RESULTS: Forty-seven RA patients participated: Birmingham (n=6 NG; 21 patients) and New York City (n=4 NG; 26 patients). They were predominantly female (85%), 70% white, with a mean age of 64.5 years and 58% had>10-year RA duration. Present/past DMARDs included methotrexate only in 6%, other traditional DMARDs in 15%, glucocorticoids in combination with traditional DMARDs in 11%, and biologics and/or Jak-kinase inhibitors in 68% of participants. Voted domains in order were: (1) efficacy/effectiveness and the onset/mode of action (78/282 votes); (2) side effects/fear of side effects (84/282 votes); (3) cost including out of pocket, co-payments and patient responsibility (54/282 votes); (4) convenience/frequency of use (27/282 votes); (5) doctor's opinion (20/282 votes); (6) other drugs/comorbidity/other patient's experience/effects on other people (3/282 votes); (7) fear of needles (8/282 votes); and (8) newness of the medication (8/282 votes). CONCLUSIONS: We identified the patient perspective regarding the choice between adding oral versus injectable DMARD once methotrexate failed to control RA disease activity. This knowledge can help in shared decision-making for DMARD choice in RA treatment.
33738615 Effects of laser acupuncture tele-therapy for rheumatoid arthritis elderly patients. 2022 Feb Rheumatoid arthritis (RA) is a progressive common autoimmune disorder and is one of the most functional limiting diseases in elderly. Until recently, its treatment is mainly based on physical locations and meetings while being face to face. However, laser acupuncture tele-therapy approaches can significantly provide the patient with safety during the COVID-19 pandemic as well as changing the disorder's prognosis. Sixty patients were assigned randomly into 2 groups with 1:1 ratio. Patients in group A are treated remotely by laser acupuncture in addition to methotrexate and a tele-rehabilitation program in the form of aerobic exercise training. Patients in group B are treated by methotrexate and a tele-rehabilitation program in the form of aerobic exercise. There was a statistically significant difference in health assessment questionnaire (HAQ) pre- and post-treatment in group A (p < 0.05). The C-reactive protein (CRP) and interleukin-6 (IL-6) inflammatory markers as well as the malondialdehyde (MDA) oxidative marker showed a significant reduction pre- and post-treatment in group A (p < 0.05). Additionally, there was a significant increase in the adenosine tri-phosphate (ATP) antioxidant marker pre- and post-treatment in group A (p < 0.05). The comparison between groups A and B showed a statistically significant post-treatment difference in RAQoL, CRP, IL-6, ATP, and MDA in group A than group B. Considering the significant improvement that was found in the laser acupuncture group, it can be concluded that the use of laser acupuncture as adjunctive was effective in the treatment of elderly patients with RA.

34373933 Sequences of biological treatments for patients with moderate-to-severe rheumatoid arthrit 2022 Jan BACKGROUND: Biologic disease-modifying antirheumatic drugs (bDMARDs) are recommended to be added in sequentially in the treatment of moderate-to-severe rheumatoid arthritis (RA). All these drugs, however, are substantially more expensive than conventional synthetic DMARDs throughout the world, including in China. The objective of this study is to evaluate the cost-effectiveness of treatment sequences of bDMARDs for patients with moderate-to-severe rheumatoid arthritis from the Chinese healthcare system perspective. METHODS: An individual patient simulation model was used to track the course of patients from first treatment through switches to further lines in a sequence. The comparator treatment sequence commenced with methotrexate, followed by non-biologic therapy. The intervention sequences were assumed to be the combinations of bDMARDs available, followed by non-biologic therapy. Life-years, quality-adjusted life-years (QALYs), and lifetime costs were estimated. Univariable and probabilistic sensitivity analyses and scenario analyses were performed to evaluate the model uncertainty. RESULTS: Compared with the comparator treatment sequence, bDMARDs sequences were associated with more life years, QALYs, and cost. These produced ICERs ranged from $27,441.36/QALY to $40,149.2/QALY, above the willingness-to-pay threshold of $10,378 per QALY. The uncertainty analyses and the scenario analyses confirmed the result of the base case analysis. CONCLUSIONS: From the perspective of the Chinese healthcare system, bDMARDs sequences are estimated not to be cost-effective compared with conventional synthetic disease-modifying antirheumatic drug strategy for patients with moderate-to-severe RA at a WTP threshold of $10,378 per QALY. Price reductions are warranted to make bDMARDs cost-effective and affordable.
