Abstract
Macrophages play an essential role in rheumatoid arthritis. Depending on their phenotype (M1 or M2), they can play a role in the initiation or resolution of inflammation. The M1/M2 ratio in rheumatoid arthritis is higher than in healthy controls. Despite this, no treatment targeting specifically macrophages is currently used in clinics. Thus, devising strategies to selectively deplete proinflammatory macrophages and promote anti-inflammatory macrophages could be a promising therapeutic approach. State-of-the-art molecular interaction maps of M1 and M2 macrophages in rheumatoid arthritis are available and represent a dense source of knowledge; however, these maps remain limited by their static nature. Discrete dynamic modelling can be employed to study the emergent behaviours of these systems. Nevertheless, handling such large-scale models is challenging. Due to their massive size, it is computationally demanding to identify biologically relevant states in a cell- and disease-specific context. In this work, we developed an efficient computational framework that converts molecular interaction maps into Boolean models using the CaSQ tool. Next, we used a newly developed version of the BMA tool deployed to a high-performance computing cluster to identify the models' steady states. The identified attractors are then validated using gene expression data sets and prior knowledge. We successfully applied our framework to generate and calibrate the M1 and M2 macrophage Boolean models for rheumatoid arthritis. Using KO simulations, we identified NFkB, JAK1/JAK2, and ERK1/Notch1 as potential targets that could selectively suppress proinflammatory macrophages and GSK3B as a promising target that could promote anti-inflammatory macrophages in rheumatoid arthritis.

Abstract
OBJECTIVE The present study compared three models of induction of osteoarthritis (OA) and rheumatoid arthritis (RA) in the temporomandibular joint (TMJ) of rats. DESIGN The induction method was by injection of complete Freund's adjuvant (CFA) + type II bovine collagen (CII). Twenty-four adult male rats were divided into four groups (n = 6): G1: Sham, 50 μL of 0.9% sodium chloride at the base of the tail and in each TMJ; G2: OA, 50 μL CFA+CII in each TMJ; G3: RA+OA, 100 μL of CFA+CII at the base of the tail and 50 μL CFA+CII in each TMJ; G4: RA, 100 μL of CFA+CII at the base of the tail. All injections were repeated 5 days later. Twenty-three days after the first injection, the animals were sacrificed and the TMJs were submitted to histomorphometric analysis and measurement of cytokines. The Kruskal-Wallis and Dunn tests were used (alpha=0.05). RESULTS The total thickness of the condylar cartilage increased in G2 in relation to the other groups, G3 and G4 reduced in relation to G1; and G2 and G4 reduced in relation to G2 and G3. The levels of IL-1β, IL-6 and TNF-α increased in the three induction models compared to G1. The level of IL-10 increased in G2 compared to the other groups and reduced in G3 and G4 compared to G1. CONCLUSION CFA+CII induced inflammation and degeneration compatible with RA (advanced chronic stage) when injected in the tail, and compatible with OA (acute stage or early disease) when injected only in the TMJ.

Abstract
Background Patients with systemic sclerosis (SSc) have poor prognosis without cure methods. We began, 10 years ago, to relieve active SSc using short-term intravenous high-dose methylprednisolone pulse (MP-Pulse) and then maintain remission using long-term and low-dose oral glucocorticoids (LTLD-GC). Methods Total 46 of SSc patients with interstitial lung disease (ILD) and induration of skin during January 2006 to December 2019 were analyzed retrospectively, who were followed up for 10 years or more. The patients were treated with MP-Pulse (15 mg/kg/day, 4 days/week, for 2 weeks) with (n=21) or without (n=25) LTLD-GC (prednisone 5–10 mg/day or methylprednisolone 4–8 mg/day). The biographic and clinical data, including occurrence of infection or any adverse reactions, were collected at baseline, 6 months, 1 year, and annually through 10 years after treatment. Results From baseline to 10 years, compared with MP-Pulse alone, MP-Pulse/LTLD-GC significantly reduced skin and lung fibrosis and improved lung function: Rodnan skin score (mRSS: 22.1±12.4 to 8.16±2.5, P<0.001), forced vital capacity (FVC: 71.7% to 89.83%, P<0.001), forced expiratory volume in the first second (FEV1: 75.7% to 87.88%, P<0.001), diffusing capacity of the lung for carbon monoxide (DLCO: 63.4% to 87.73%, P<0.001), and high-resolution chest computerized tomography scan (HRCT score: 3.96±2.81 to 1.42±0.83, P<0.001). None of the 46 patients had femoral head necrosis, compression fracture, death, or life-threatening adverse events. Conclusion These outcomes indicate that intravenous MP-Pulse combined with oral LTLD-GC could achieve significant remission and better long-term (10 years) efficacy without severe adverse effects in SSc patients with ILD and induration of skin.

Abstract
Dexamethasone sodium phosphate (Dex) is widely used in the clinic for the treatment of rheumatoid arthritis. However, it circulates in blood for a short time and it is linked to high risk of severe side effects caused by repeated dosing. Here, we encapsulated Dex onto zeolitic imidazolate framework-8 (ZIF-8) to prepare metal-organic framework nanoparticles with high drug loading efficiency. To prevent clearance by the mononuclear phagocyte system and extend time in circulation, the nanoparticles were also camouflaged with macrophage-derived microvesicles (MV) to obtain the biomimetic drug delivery system MV/Dex/ZIF-8. In vitro and in vivo experiments showed that the nanosystem had high drug loading and encapsulation efficiency, high stability, and long circulation time, and it permitted sustained drug release longer in inflamed joint tissues. Our study provides new insights into designing camouflaged drug carriers to prevent their phagocytosis and prolong their time in circulation.

Abstract
Rheumatoid arthritis (RA) carries significant risk for atherosclerotic cardiovascular disease (ASCVD). Traditional ASCVD risk factors fail to account for this accelerated atherosclerosis. Shared inflammatory pathways are fundamental in the pathogenesis of both diseases. Considering the impact of RA in increasing cardiovascular morbidity and mortality, the characterization of therapies encompassing both RA and ASCVD management merit high priority. Despite little progress, several drugs discussed here promote remission and or lower rheumatoid disease activity while simultaneously conferring some level of atheroprotection. Methotrexate, a widely used disease-modifying drug used in RA, is associated with significant reduction in cardiovascular adverse events. MTX promotes cholesterol efflux from macrophages, upregulates free radical scavenging and improves endothelial function. Likewise, the sulfonamide drug sulfasalazine positively impacts the lipid profile by increasing HDL-C, and its use in RA has been correlated with reduced risk of myocardial infraction. In the biologic class, inhibitors of TNF-α and IL-6 contribute to improvements in endothelial function and promote anti-atherogenic properties of HDL-C, respectively. The immunosuppressant hydroxychloroquine positively affects insulin sensitization and the lipid profile. While no individual therapy has elicited optimal atheroprotection, further investigation of combination therapies are ongoing.

Abstract
Arthritis has been a heavy burden on the economy and society at large. Recently, nanomaterials that can convert near-infrared light into localized heat have demonstrated better targeting to arthritic joints, fewer side effects, ease of combined application with current therapeutics and enhanced efficacy for arthritis treatment. In this review, the authors summarize traditional thermal therapies for arthritis treatment and their molecular mechanisms and discuss the advantages and applications of nanotechnology-based thermal therapies for arthritis treatment. In conclusion, nanotechnology-based thermal therapies are effective alternatives or adjuvant strategies to the current pharmacological treatment of arthritis. Future clinical translation of thermal therapies could benefit from research elucidating their mechanisms and standardizing their parameters to optimize efficacy.

Abstract
Introduction:Systemic lupus erythematosus (SLE) is a systemic autoimmune disease with extreme heterogeneity, which sometimes may be life-threatening. Principles of treat to target (T2T) in SLE were put forward more recently, leading to better long-term survival and reduced damage accrual.Areas covered: Lupus low disease activity state (LLDAS) and remission are currently the most widely accepted principal goals of SLE-T2T recommendations. In this article, we will deliver the novel insights into the definitions of LLDAS/remission, attainability, and, most importantly, clinical predictors of LLDAS and remission in SLE.Expert opinion: Since the release of the LLDAS and the framework on definitions of remission in SLE, there has been much evidence of a correlation between target attainment or maintenance and better prognosis. In the meantime, researchers are searching for predictors of target attainment. Noteworthy, prospective randomized trials are lacking worldwide to verify the benefits of T2T in various aspects of SLE. The most essential issue is that the optimal definition of the therapeutic target for SLE remains controversial, particularly regarding the maintenance dose of prednisone, the need for immunosuppressive withdrawal, and the requirement for serologic conversion. How to implement T2T principles in clinical practice also needs further investigation.

Abstract
Ulcerative colitis (UC) is an idiopathic inflammatory condition of colorectal regions. Existing therapies for UC face grave lacunae including off-target and other harmful side effects, extensive first-pass metabolism, rapid clearance, limited or poor drug absorption and various other limitations, resulting in lower bioavailability. These conditions demand advanced delivery strategies to inflammatory colonic conditions so that drugs can counter stomach acid, avail protective strategies at this pH and selectively deliver drugs to the colon. Therefore, this approach was undertaken to develop and characterize nanoparticles for the delivery of drugs glycyrrhizic acid as well as budesonide in UC. Biocompatible and biodegradable aminocellulose-conjugated polycaprolactone containing budesonide was covered onto gelatinous nanoparticles (NPs) loaded with GA. Nanoparticles were prepared by the solvent evaporation technique, which showed particle size of ∼230 nm, spherical shape, almost smooth morphological characters under transmission, scanning and atomic force microscopy. These NPs also improved disease activities like occult blood in the stool, length of the colon and fecal properties. The nanoparticle therapy appreciably decreased colonic mast cellular infiltration, significantly maintained mucin protection, ameliorated histological features of the colon. Furthermore, markers of inflammation such as iNOS, COX-2, IL1-β, TNF-α, NO, and MPO were also appreciably ameliorated with the therapy of dual drug-loaded nanoparticles. Overall, these results establish that dual drug-loaded core-shell NPs exhibit superior therapeutic properties over the free or naïve forms of GA and budesonide in acute colon inflammation and present advantages that may be assigned to their ability to significantly inhibit colon inflammatory conditions.

Abstract
Objective This study was aimed to analyze the prescription pattern of disease modifying anti-rheumatic drug (DMARD) therapy in patients with rheumatoid arthritis (RA) in a tertiary care teaching hospital in Uttarakhand, India. Methodology This cross-sectional study was conducted in 150 RA patients who were given DMARD therapy. Patient's demographic details, drugs prescribed with their dosage and administration routes and the usage of complementary and alternative medicine (CAM) therapy were recorded to study the prescription pattern. Results Overall, 4 DMARDs were prescribed in all the studied patients: Methotrexate (n = 150), hydroxychloroquine (n = 35), leflunomide (n = 5), and adalimumab (n = 1). Single DMARD therapy with methotrexate was prescribed to 110 (73.3%) followed by double therapy with methotrexate + hydroxychloroquine in 35 (23.3%), triple therapy (methotrexate + hydroxychloroquine + leflunomide) in 4 (2.7%) and triple therapy with biological DMARD (methotrexate + hydroxychloroquine + leflunomide + adalimumab) in 1 (0.7%) patient. Adjuvant therapy drugs included: Prednisolone (n = 150), folic acid (n = 150), naproxen (n = 150), calcium (n = 150), vitamin D (n = 150) and indomethacin (n = 40). Of the total, 61.4% patients also took complimentary alternative medicine (CAM) therapy. Conclusion Our study concludes that the most commonly prescribed DMARDs in our setting, to patients of RA, in descending order of frequency were methotrexate, followed by hydroxychloroquine, leflunomide and lastly adalimumab. A total of five adjuvant medications were commonly prescribed to all patients. There was a high prevalence of self-medicated CAM therapy in the majority of these patients.

Abstract
OBJECTIVE To retrospectively evaluate whether oral glucocorticoid (GC) administration can be tapered or discontinued over a 2-year observation period in patients with rheumatoid arthritis (RA) undergoing a stable oral GC treatment, without deterioration in the disease status. METHODS Methotrexate (MTX) and prednisolone (PSL) dosages were increased and decreased, respectively, to the maximum extent possible. Concomitant biological or targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) were used as required. Changes in PSL and MTX use and disease status were evaluated at baseline (BL), year-1, and year-2. RESULTS Thirty-six patients were enrolled (median age, 65.4 years; disease duration, 7.1 years). The proportion of patients using PSL decreased over 2 years (100-13.9%, p < .0001). While no change was observed in the proportion of patients using MTX, the average administered dose increased at year-1 (p = .06). Moreover, b/tsDMARDs were administered in nine patients (two in year-1, seven in year-2). The Clinical Disease Activity Index remission rate increased from 25.0% to 38.9%. Serious adverse events were identified in two patients. CONCLUSIONS Oral GC administration was discontinued without deterioration in the rheumatoid arthritis disease control.

Abstract
Muscle atrophy decreases physical function and overall health. Increased glucocorticoid production and/or use of prescription glucocorticoids can significantly induce muscle atrophy by activating the glucocorticoid receptor, thereby transcribing genes that shift protein balance in favor of net protein degradation. Although mechanical overload can blunt glucocorticoid-induced atrophy in young muscle, those affected by glucocorticoids generally have impaired force generation. It is unknown whether contractile force alters the ability of resistance exercise to mitigate glucocorticoid receptor translocation and induce a desirable shift in protein balance when glucocorticoids are elevated. In the present study, mice were subjected to a single bout of unilateral, electrically induced muscle contractions by stimulating the sciatic nerve at 100 Hz or 50 Hz frequencies to elicit high or moderate force contractions of the tibialis anterior, respectively. Dexamethasone was used to activate the glucocorticoid receptor. Dexamethasone increased glucocorticoid signaling, including nuclear translocation of the receptor, but this was mitigated only by high force contractions. The ability of high force contractions to mitigate glucocorticoid receptor translocation coincided with a contraction-mediated increase in muscle protein synthesis, which did not occur in the dexamethasone-treated mice subjected to moderate force contractions. Though moderate force contractions failed to increase protein synthesis following dexamethasone treatment, both high and moderate force contractions blunted the glucocorticoid-mediated increase in LC3 II:I marker of autophagy. Thus, these data show that force generation is important for the ability of resistance exercise to mitigate glucocorticoid receptor translocation and promote a desirable shift in protein balance when glucocorticoids are elevated.NEW & NOTEWORTHY Glucocorticoids induce significant skeletal muscle atrophy by activating the glucocorticoid receptor. Our work shows that muscle contractile force dictates glucocorticoid receptor nuclear translocation. We also show that blunting nuclear translocation by high force contractions coincides with the ability of muscle to mount an anabolic response characterized by increased muscle protein synthesis. This work further defines the therapeutic parameters of skeletal muscle contractions to blunt glucocorticoid-induced atrophy.

Abstract
Rheumatoid arthritis (RA) is a chronic autoimmune disorder and serious cause of disability. Despite considerable advances in RA management, challenges like extensive drug metabolism and rapid clearance causes poor bioavailability. Core-shell nanocarriers for co-delivery of glycyrrhizic acid (GA) and budesonide against RA were developed. GA-loaded gelatin nanoparticles (NPs) were synthesized and coated with budesonide encapsulated aminocellulose-grafted polycaprolactone (PCL-AC). GA- and budesonide-loaded PCL-AC-gel NPs had diameter of 200-225 nm. Dual drug-loaded (DDL) NPs reduced joint swelling and erythema in rats while markedly ameliorating bone erosion evidenced by radiological analysis, suppressed collagen destruction, restored synovial tissue, bone and cartilage histoarchitecture with reduced inflammatory cells infiltration. NPs also reduced various inflammatory biomarkers such as TNF-α, IL-1β, COX-2, iNOS. Results of this study suggest that dual NPs exerted superior therapeutic effects in RA compared to free drugs which may be attributed to slow and sustained drug release and NPs' ability to inhibit inflammatory mediators.

Abstract
Background: The biologic disease-modifying antirheumatic drugs (bDMARDs) are currently incorporated as part of the pharmacotherapy management of inflammatory arthritis (IA). Adherence to bDMARDs is crucial to ensure treatment success in IA. However, most of the recent studies evaluated adherence level in patients using subcutaneous injections of bDMARDs utilized the indirect methods adapted from adherence assessment for oral medication. Aim: This study aimed to develop a questionnaire to assess adherence to the self-injectable subcutaneous bDMARDs. Methods: The development of the Subcutaneous bDMARDs Adherence Score (SCADS) involved evaluation of content validity. Literature reviews provide the basis for domain identification and item formation. Four experts evaluated the instrument by using a four-point ordinal scale with a rubric scoring on relevance, importance, and clarity of each item in measuring the overarching construct. The item-level content validity index (I-CVI) and the scale-level content validity index (S-CVI) were calculated. The factor structure and internal consistency reliability of SCADS were estimated using principal component analysis (PCA) and Cronbach's alpha, respectively. Results: Both S-CVI/UA (universal agreement) and the average item-level content validity index (S-CVI/Ave) (average) for the entire instrument showed excellent criteria with a value of >0.90. Cronbach's alpha coefficient value for SCADS was 0.707 indicating good internal consistency. All items showed corrected item-total correlation coefficients above 0.244. Questionnaire items with a factor loading of 0.30 or above were considered in the final factor solution. The factor analysis resulted in 3-factor solutions, which corresponded to 66.62% of the total variance. Conclusion: The SCADS is a consistent and reliable instrument for evaluating adherence among IA patients using the subcutaneous bDMARDs. It is simple to use, yet comprehensive but still requiring further clinical and international validation.

Abstract
The main aim of the current research was to develop a modified cyclodextrin based nanoparticulate drug delivery system to deliver dexamethasone sodium phosphate (DSP) for the treatment of rheumatoid arthritis (RA). DSP is a glucocorticoid (GC), and its limited application in RA therapy due to poor pharmacokinetics and its severe associated side effects. DSP loaded hydrophobically modified cyclodextrin based nanoparticles (DSP-NPs) prepared by a double emulsion solvent evaporation method. The nanoparticle size was <120 nm, good entrapment efficiency and excellent stability were obtained. TEM study showed that nanoparticles were perfectly spherical shape. The in-vitro drug release from nanoparticle follows the non-Fickian diffusion mechanism. The pharmacokinetic profile of DSP after encapsulation showing the 2.3-fold increase in AUC and extended mean residence time, which increases the chances of nanoparticles to extravasate into the site of inflammation by the EPR effect. The pharmacodynamic studies in the Adjuvant-induced Arthritis (AIA) rat model showing a significant reduction in arthritic score, paw thickness, and inflammatory cytokine level in serum. Adverse effects evaluation studies demonstrate a significant reduction in the associated undesirable effects on body weight, blood glucose level, renal impairment, and hematological abnormalities compared to marketed formulation. These results suggest that DSP-NPs can be used as an efficient therapy for RA.

Abstract
We evaluated the effects of glucocorticoids on bone mineral density (BMD), and prevalence of osteoporosis and fracture in rheumatoid arthritis (RA) by meta-analysis. Until June 26, 2019, we conducted a systematic literature search in EMBASE, Web of science, PubMed, and Cochrane Library to obtain BMD and the prevalence of osteoporosis and fracture in glucocorticoid-treated subjects with RA. The BMD of the treatment and control groups were analyzed by meta-analysis (Stata. version 15), and the 95% confidence interval (CI) was calculated. We identified 15 observational studies, including 46,711 RA subjects and 857 healthy controls. The BMD of the lumbar spine (- 0.038 g/cm2; CI, - 0.052, - 0.024) and femoral neck (- 0.017 g/cm2; - 0.030, - 0.003) in RA treated with glucocorticoids were significantly lower than those in RA controls. Compared with healthy control group, the BMD of the lumbar spine (- 0.094 g/cm2; - 0.126, - 0.061) and femoral neck (- 0.097 g/cm2, - 0.109, - 0.085) of RA treated with glucocorticoids decreased more significantly. The prevalence of osteoporosis in whole body, spine, and femur was 38.6% (0.305, 0.466), 32.9% (0.277, 0.381), and 21.7% (0.106, 0.328), respectively. And the prevalence of vertebral fracture was 13.0% (0.058, 0.203). Glucocorticoids may lead to a decline in skeletal health in subjects with RA, especially in vertebral and femoral BMD, compared with normal people or RA without glucocorticoid therapy. Meanwhile, osteoporosis and fractures were also common. Therapeutic measures should be targeted at individuals, which needs further study. Through meta-analysis, we found that glucocorticoids have some negative effects on the bone health of subjects with rheumatoid arthritis. Therefore, when using glucocorticoids to treat rheumatoid arthritis, we should take strategic measures to prevent the decline of bone quality.

Abstract
Deregulated NF-k activation is not only involved in cancer but also contributes to the pathogenesis of chronic inflammatory diseases like rheumatoid arthritis (RA) and multiple sclerosis (MS). Ideally, therapeutic NF-KappaB inhibition should only take place in those cell types that are involved in disease pathogenesis to maintain physiological cell functions in all other cells. In contrast, unselective NF-kappaB inhibition in all cells results in multiple adverse effects, a major hindrance in drug development. Hitherto, various substances exist to inhibit different steps of NF-kappaB signaling. However, powerful tools for cell-type specific NF-kappaB inhibition are not yet established. Here, we review the role of NF-kappaB in inflammatory diseases, current strategies for drug delivery and NF-kappaB inhibition and point out the “sneaking ligand” approach. Sneaking ligand fusion proteins (SLFPs) are recombinant proteins with modular architecture consisting of three domains. The prototype SLC1 binds specifically to the activated endothelium and blocks canonical NF-kappaB activation. In vivo, SLC1 attenuated clinical and histological signs of experimental arthritides. The SLFP architecture allows an easy exchange of binding and effector domains and represents an attractive approach to study disease-relevant biological targets in a broad range of diseases. In vivo, SLFP treatment might increase therapeutic efficacy while minimizing adverse effects.

Abstract
INTRODUCTION Glucocorticoids (GCs), especially low-dose GCs, are commonly prescribed for rheumatoid arthritis (RA), although the risk/benefit ratio is controversial. A randomized, double-blind clinical trial was performed to evaluate the efficacy and safety of low-dose oral GCs combined with methotrexate (MTX) and hydroxychloroquine (HCQ) in early RA (ERA). METHODS Eighty untreated ERA patients were randomized into the trial (GCs + MTX + HCQ) and control (placebo + MTX + HCQ) groups, for 1-year treatment. Therapeutic evaluation indices were American College of Rheumatology (ACR) 20 of ACR, disease activity score (DAS) 28- erythrocyte sedimentation rate (ESR), visual analog scale scores, joint function, health assessment questionnaire-disability index score, morning stiffness duration, C-reaction protein and ESR. The clinical indicators were evaluated pre-treatment and at 1st, 3th, 6th and 12th month of treatment. The MRI data of single joint (ie, the most swollen joint) for each patient were acquired with a revised OMERACT RAMRIS Scoring System before and after treatment. The correlation analysis was adopted to confirm whether the efficacy of GC treatment is related to the time of RA onset. The side effects (eg, gastrointestinal reactions, liver dysfunction, upper respiratory tract infection, leukocyte reduction) were also monitored. RESULTS At 1st month, 55% and 20% cases in the experimental and control groups achieved ACR20 response, respectively, indicating a significant difference (χ = 16.157, P < .001). This trend continued until 6th month. At 12th month, the number of patients achieved ACR20 response was similar in both groups. At 1st to 6th month, DAS28- ESR scores in the experimental group were significantly lower than control values (all p < .05). The experimental group showed improved inflammation, quality of life and radiological symptoms. Bone erosion remained unchanged in the experimental group, while worsening in control group. Correlation coefficients between RA duration and DAS28-ESR score were 0.496, 0.464, 0.509, and 0.550 at 1st, 3th, 6th, and 12th month, respectively. No differences were found in adverse events between the 2 groups. CONCLUSIONS Low-dose GCs combined with MTX and HCQ significantly achieves disease remission indexed by ACR20 and DAS28-ESR, and improves clinical and radiological outcomes in ERA patients at the early stage, with superiority over placebo + MTX + HCQ, without enhancing adverse reactions.

Abstract
Systemic lupus erythematosus (SLE), a common lethal autoimmune disease, is characterized by effector/regulatory T cells imbalance. Current therapies are either inefficient or have severe side effects. MicroRNA-125a (miR-125a) can stabilize Treg-mediated self-tolerance by targeting effector programs, but it is significantly downregulated in peripheral T cells of patients with SLE. Therefore, overexpression of miR-125a may have therapeutic potential to treat SLE. Considering the stability and targeted delivery of miRNA remains a major challenge in vivo, we constructed a monomethoxy (polyethylene glycol)-poly(d,l-lactide-co-glycolide)-poly(l-lysine) (mPEG-PLGA-PLL) nanodelivery system to deliver miR-125a into splenic T cells. Results demonstrate that miR-125a-loaded mPEG-PLGA-PLL (PEALmiR-125a) nanoparticles (NPs) exhibit good biocompatibility and protect miR-125a from degradation, thereby prolonging the circulatory time of miRNA in vivo. In addition, PEALmiR-125a NPs are preferentially enriched in a pathological spleen and efficiently deliver miR-125a into the splenic T cells in SLE mice models. The PEALmiR-125a NPs treatment significantly alleviates SLE disease progression by reversing the imbalance of effector/regulatory T cells. Collectively, the PEALmiR-125a NPs show excellent therapeutic efficacy and safety, which may provide an effective treatment for SLE.

Abstract
Abstract
Objectives
To evaluate the attainability of Lupus Low Disease Activity State (LLDAS) and definitions of remission in SLE (DORIS) in a treatment-naïve cohort of SLE.
Methods
LLDAS5 was defined as LLDAS with a prednisone dose ≤5 mg/day. There were four definitions in DORIS: clinical remission on treatment (RONT), complete RONT, clinical remission off treatment (ROFT) and complete ROFT. The treatment-naïve patients from Peking University First Hospital SLE cohort were enrolled. The time to each state and their annual cumulative probabilities were estimated. The frequencies of patients who achieved each component of LLDAS or DORIS during follow-up were determined. The predictors of time to each state were identified.
Results
A total of 218 patients were included, with a median follow-up of 4.48 years. Respectively, 190 (87.2%), 160 (73.4%), 148 (67.9%), 94 (43.1%), 23 (10.6%) and 18 (8.3%) patients achieved LLDAS, LLDAS5, clinical RONT, complete RONT, clinical ROFT and complete ROFT. The median time to LLDAS, LLDAS5, clinical RONT and complete RONT were 1.4, 2.3, 2.6 and 4.7 years, respectively. Positive anti-dsDNA, RP and anaemia were significantly associated with prolonged time to LLDAS, LLDAS5 or clinical RONT.
Conclusion
Our data confirmed that LLDAS is an attainable early treatment target for SLE. Though with more difficulty, RONT can be achieved in two-thirds of our patients. ROFT may not be an ideal treatment target at present as it is only attained in few patients.

Abstract
BACKGROUND In rheumatoid arthritis (RA) trials, inclusion of patients on background treatment with glucocorticoids (GCs) might impact efficacy and safety outcomes. OBJECTIVES To determine if inclusion of patients on background GC use influenced efficacy and safety outcomes of RA randomised clinical trials on initiation of tocilizumab (TCZ) or adalimumab (ADA) or methotrexate (MTX) monotherapy. METHODS Data of four double-blind RA randomised controlled trials (AMBITION, ACT-RAY, ADACTA and FUNCTION) with in total four TCZ, one ADA and two MTX monotherapy arms were analysed. Analyses of covariance of changes from baseline to week 24 in efficacy endpoints and radiographic progression up to week 104 were performed, correcting for relevant covariates. Incidence rates of serious adverse events (SAEs) were assessed. RESULTS No statistically significant differences were found in efficacy parameters between background GC users and non-GC users, except for less radiographic progression associated with GC usage in one MTX arm. SAE rates were not statistically significantly different between GC users and non-GC users in the treatment arms. CONCLUSION No effect of including patients on background GC treatment on efficacy and safety trial outcomes was found, with the exception of reduced radiological joint damage in one MTX arm.

Abstract
Introduction Anticitrullinated peptide antibody (ACPA) responses for 22 citrullinated peptides in patients with early rheumatoid arthritis (RA) were analysed and related to radiological and clinical outcome during the first 2 years in a prospective inception cohort. Methods The ACPA reactivities were assessed in 1022 patients with early RA (symptoms <12 months) using the custom-made microarray chip (Thermo Fisher Scientific, Uppsala, Sweden) in a prospective longitudinal study of observational assessments of Disease Activity Score (DAS28 and its components) and radiology during the first 24 months, accounting for the treatment. Results Frequency of ACPA reactivities varied between 13.3% and 63.1%. Of the anticyclic citrullinated peptide-2 (anti-CCP2) antibody-negative patients, ACPA reactivities were positive in 32.6%. Smoking, human leucocyte antigen-shared epitope (HLA-SE), anti-CCP2/rheumatoid factor, protein tyrosine phosphatase non-receptor type 22 (1858C/T) and DAS28 were significantly associated with number of ACPA reactivities. The ACPA reactivities modified differently the development of DAS28 over 24 months (identified using trajectories). Anti-Filaggrin307-324, anti-hnRNP (Peptide)-Z1 and anti-F4-CIT-R antibodies anticipated lower DAS28 values (p<0.01–0.05), while positivity for anti-Fibrinogen(Fib)β62-78(74), and anti-Fibα563-583 predicted higher DAS28 (p<0.01 both). Interaction between anti-Fibß36-52, anti-Pept-5 and anti-Bla-26 antibodies, respectively, and DAS28 during 24 months decreased significantly the DAS28 values (p<0.01–0.05). Corticosteroids and biologicals were related to DAS28-area under the curve and Larsen score 24 months. Anti-vimentin2-17 antibodies remained significantly associated with Larsen score at baseline and 24 months, respectively, and radiological progression, besides biologicals at 24 months adjusted for sex and age. Conclusions Several ACPA reactivities modified significantly the DAS28 development during the first 24 months and were significantly associated with Larsen score at baseline, 24 months and radiological progression.

Abstract
Polymeric nanoparticles (NPs) are strong candidates for the development of systemic and targeted drug delivery applications. Their size is a determinant property since it defines the NP-cell interactions, drug loading capacity, and release kinetics. Herein, poly(d,l-lactic acid) (PDLA) NPs were produced by the nanoprecipitation method, in which the influence of type and concentration of surfactant as well as PDLA concentration were assessed. The adjustment of these parameters allowed the successful production of NPs with defined medium sizes, ranging from 80 to 460 nm. The surface charge of the different NPs populations was consistently negative. Prednisolone was effectively entrapped and released from NPs with statistically different medium sizes (i.e., 80 or 120 nm). Release profiles indicate that these systems were able to deliver appropriate amounts of drug with potential applicability in the treatment of inflammatory conditions. Both NPs populations were cytocompatible with human endothelial and fibroblastic cells, in the range of concentrations tested (0.187-0.784 mg/mL). However, confocal microscopy revealed that within the range of sizes tested in our experiments, NPs presenting a medium size of 120 nm were able to be internalized in endothelial cells. In summary, this study demonstrates the optimization of the processing conditions to obtain PDLA NPs with narrow size ranges, and with promising performance for the treatment of inflammatory diseases. © 2018 Wiley Periodicals, Inc.

Abstract
Objectives: Little information is available on the characteristics of elderly patients starting TNFα antagonist treatment for rheumatoid arthritis (RA). The objective of this work was to compare prescription patterns in RA patients younger vs. older than 75 years. Methods: Biologic-naive patients with active RA (DAS28 > 3.2) despite first-line therapy were included between 2007 and 2009 in the prospective, multicentre, longitudinal, observational, population-based CORPUS-RA cohort. TNFα antagonist users were defined as having received at least one TNFα antagonist during the first study year. The groups < 75 years and ≥ 75 years were compared regarding comorbidities, inflammation (CRP and ESR), disease activity (DAS28), disability (HAQ-DI), number of physician visits, and treatment. To verify the impact of the cut off, we also compared patients aged 70 years or more to patients younger than 70 years. Results: Of 543 RA patients, 382 had complete one-year follow-up data, including 114 TNFα antagonist users, 3 (6%) among the 49 patients aged 75 years or over and 111 (32%) of the 333 patients younger than 75 years (p < 0.01). Disease activity in the two age groups was similar at inclusion and after one year. Comorbidities and a history of auto-immunity were more common in the older group. Compared to their younger counterparts, the older patients received glucocorticoids more often (p = 0.003) and synthetic disease-modifying anti-rheumatic drugs less often (p = 0.01). Conclusion: TNFα antagonists are used less often and glucocorticoids more often in elderly patients with active RA compared to their younger counterparts. The fact that this study was performed in 2007–9 is a limitation in terms of relevance to today’s patients and further studies should be conducted in new cohorts of active RA.

Abstract
BACKGROUND Dexamethasone (DEX) is an effective therapeutic option commonly used in the treatment of many inflammatory diseases. However, DEX could impair proliferation or differentiation of osteoblasts, suggesting a pivotal role of DEX in bone destruction. OBJECTIVE To investigate whether intraarticular injection of DEX could exacerbate bone erosion during CIA development. SETTING Collagen-induced arthritis (CIA) mice were divided into PBS-treated and DEX-treated groups (n = 5/group). Negative control group: DBA/1 mice (n = 5) were used as age-matched, healthy, untreated controls. METHOD CIA was induced in male DBA/1 mice. Intraarticular injected DEX (0.01 mg/Kg, 10 μl) into the knee joint of CIA on Day 28, Day 35, Day 42 and Day 49 post the 1st immunization. RESULTS The severity of the arthritic disease was ameliorated in DEX-treated mice, accompanied by the decreased expression of IL-6, IL-8 and TNF-α. However, DEX treatment accelerates bone erosion and osteoporosis during CIA development and triggers higher expression of RANKL, IL-17 in vitro and vivo. MAIN OUTCOME MEASURE The effect of DEX on bone structure was analyzed using Haematoxylin & Eosin (H&E) staining and Micro-CT. The levels of receptor activator for nuclear factor-κ B ligand (RANKL) and osteoprotegerin (OPG) were investigated by real-time PCR, Western Blot and immunohistochemical analysis. RASFs were stimulated with Interleukin (IL)-1β and then treated with different concentrations of DEX for 72 h. CONCLUSION Intraarticular injection of DEX could exacerbate bone erosion in CIA model via up-regulation of RANKL expression.

Abstract
Background: Chronic non-malignant lung diseases such as chronic obstructive pulmonary disease (COPD) and interstitial lung diseases (ILD) result in reduced quality of life (QoL), a high symptom burden and reduced survival. Patients with chronic non-malignant lung disease often have limited access to palliative care. The symptom burden and the QoL of these patients resembles patients with cancer and the general palliative approach is similar. However, the disease trajectory is often slow and unpredictable, and the palliative effort must be built on accessibility, continuity and professional competences. The Danish Health Authority as well as the WHO recommends that there is access to palliative care for all patients with life-threatening diseases regardless of diagnosis. In 2011, the Danish Health Authority requested that the national medical societies would to formulate guidelines for palliation. Methods: In 2015, a group of members of the Danish Respiratory Society (DRS) was appointed for this purpose. It was composed of experienced ILD and COPD researchers as well as clinicians from different parts of Denmark. A literature review was made, a draft was prepared, and all recommendations were agreed upon unanimously. Results: The Danish version of the position paper was finally submitted for review and accepted by all members of DRS. Conclusion: In this position paper we provide recommendations on the terminology of chronic and terminal lung failure, rehabilitation and palliative care, advanced care planning, informal caregivers and bereavement, symptom management, the imminently dying patient, and organization of palliative care for patients with chronic non-malignant lung diseases.

Comparison of rituximab and conventional adjuvant therapy for pemphigus vulgaris: A retrospective analysis. PLoS One 2018; 13:e0198074.

Abstract
Background Rituximab is a promising steroid sparing agent used in the treatment of moderate to severe pemphigus vulgaris. Its exact place in the algorithm of pemphigus treatment, vis-à-vis other, conventional adjuvant therapy (CAT) is not known. Objective To describe and compare disease course outcomes and morbidity among patients with moderate to severe pemphigus who received rituximab therapy (RT) in addition to prednisone and CAT, versus those who were treated with prednisone and CAT alone. Methods A 16-year retrospective case control study was designed with adult patients who were seen at the Duke University Dermatology Immunodermatology clinic from 1999–2015, who had a diagnosis of pemphigus vulgaris, and required prednisone and at least 1 systemic CAT. All patients had at least 6 months follow up from the initial visit. Interventions included RT, systemic CAT, and prednisone. The main outcome measured was prednisone intake. Secondary outcomes were complete remission (CR) and partial remission (PR). Results 40 patients were included in the study. All initially received prednisone and at least 1 systemic CAT. 13/40 eventually went on to receive RT, while 27/40 remained on CAT (CAT-only). Patients in the RT group, pre-RT, had a median prednisone intake of 658.57 mg/month. Rituximab treatment significantly reduced this to 177.22 mg/month (p = 0.002). Median prednisone intake of the CAT-only group was 141.33 mg/month. This was significantly less than Pre-RT (p = 0.01) and on par with Post-RT intake (p = 0.58). 54% of patients in the RT group and 64% of those in the CAT-only group achieved CR. All patients in the RT group and 96% of those in the CAT-only group achieved at least PR. Conclusions 32.5% of our patients with moderate to severe pemphigus vulgaris failed prednisone and traditional CAT treatment and required rituximab therapy. Rituximab reduced the monthly prednisone intake in these patients by 73%. This suggests that a subset of patients with moderate to severe pemphigus may benefit from early institution of rituximab therapy. Rituximab significantly reduces the monthly prednisone requirement among CAT-resistant pemphigus vulgaris patients to levels on par with CAT-responsive patients.

Abstract
Objectives Methotrexate is considered to be first-line therapy for rheumatoid arthritis (RA). However, a substantial proportion of treated patients do not achieve the desired goals of therapy. This analysis aimed to identify predictors of insufficient response to methotrexate in patients with early RA. Methods The Optimal Protocol for Treatment Initiation with Methotrexate and Adalimumab (OPTIMA) and PREMIER studies in patients with RA for <1 and <3 years, respectively, examined the efficacy of methotrexate and adalimumab in methotrexate-naive patients. This post hoc analysis included patients for whom initial methotrexate monotherapy was not successful after 6 months. Candidate predictors of insufficient response and clinically relevant radiographic progression (CRRP) included demographics, baseline disease characteristics and time-averaged disease variables over a 12-week interval. In OPTIMA, adalimumab was added to therapy after insufficient treatment response; in PREMIER, initial methotrexate therapy was continued; clinical, functional and radiologic outcomes were assessed after 1 year. Results Baseline 28-joint Disease Activity Score based on C-reactive protein (DAS28(CRP)) and time-averaged DAS28(CRP) over 4, 8 and 12 weeks were the strongest predictors of insufficient response to methotrexate and CRRP. Addition of adalimumab to methotrexate therapy was associated with better clinical, functional and radiographic outcomes after 1 year compared with continuing on methotrexate monotherapy. Conclusions In patients with early RA, baseline disease characteristics and early disease activity can predict response to methotrexate treatment and radiographic progression at 6 months. The addition of adalimumab at 6 months after methotrexate failure is associated with improved outcomes. These results support treatment-to-target strategies and timely adaptation of therapy in patients with early RA. Trial registration number NCT00420927, NCT00195663; Post-results.

Abstract
Background Corticosteroid is an effective therapeutic option for inflammatory bowel disease flares, but its adverse effects may compromise treatment adherence and reduce patients’ quality of life. There is lack of data on the incidence of corticosteroid-induced mood changes in this patient population, which may be underappreciated by healthcare providers in clinical practice and interfere with optimal care. This study aimed to determine the rate of mood changes in this patient population. Methods In this prospective observational study, adult outpatients treated with prednisone for inflammatory bowel disease flares were considered for inclusion. Participants completed validated questionnaires (Beck Depression Inventory-II and Activation Subscale of Internal State Scale version two) before starting prednisone, after two weeks of prednisone, and at the end of prednisone taper to assess for mood changes. Harvey-Bradshaw Index and Simple Clinical Colitis Activity Index were used to monitor clinical disease activity. Results Fifty-three subjects were included in the analyses. The rate of mood change after two weeks of prednisone was 49.1%, primarily driven by increase in mood towards (hypo)mania. Younger age was an independent risk factor. Mood state returned to pretreatment level at the end of treatment. There was no correlation between clinical disease activity change and mood change. Conclusions Oral prednisone for inflammatory bowel disease flare is associated with high rate of mood change. As prednisone is a critical part of induction therapy, ways to minimize this adverse event must be studied. For now, healthcare providers should inform patients and monitor closely for this adverse event.

Abstract
The current review on glucocorticoids (GCs), inflammation and bone is focused on three aspects: (1) the mutual effects between GCs, inflammation and bone in inflammatory rheumatic diseases, (2) current views on fracture risk assessment in patients using GCs and (3) non-pharmacological and pharmacological treatment to prevent fractures in GC-using patients with inflammatory rheumatic diseases. The use of GCs results in increased risk for fractures due to both direct and indirect negative effects of GCs on bone mass, and on bone and muscle strength. However, also the underlying inflammatory rheumatic disease is associated with the increased bone loss and fracture risk due to the chronic inflammation itself, and due to disability/immobility caused by active disease or joint destruction. The rapid and strong anti-inflammatory effect of GCs in patients with rheumatoid arthritis seems to balance the negative effects of GCs on bone in the early, active phase of the disease. Recently, an update of the American College of Rheumatology guidelines for prevention and treatment of GC-induced osteoporosis was published with renewed recommendations. To prevent fractures, general measures, including treatment of the underlying inflammatory disease adequately (even with GCs when indicated), a healthy lifestyle, including adequate calcium and vitamin D supplementation, and regular weight bearing exercises are important. In rheumatic patients with high fracture risk using GCs, especially when the cumulative dose is high and/or the underlying inflammatory disease is active, treatment with anti-osteoporotic drugs, usually an oral bisphosphonate, is indicated.

Abstract
BACKGROUND Giant cell arteritis (GCA) is a relatively common form of primary systemic vasculitis, which, if left untreated, can lead to permanent sight loss. We compared ultrasound as an alternative diagnostic test with temporal artery biopsy, which may be negative in 9-61% of true cases. OBJECTIVE To compare the clinical effectiveness and cost-effectiveness of ultrasound with biopsy in diagnosing patients with suspected GCA. DESIGN Prospective multicentre cohort study. SETTING Secondary care. PARTICIPANTS A total of 381 patients referred with newly suspected GCA. MAIN OUTCOME MEASURES Sensitivity, specificity and cost-effectiveness of ultrasound compared with biopsy or ultrasound combined with biopsy for diagnosing GCA and interobserver reliability in interpreting scan or biopsy findings. RESULTS We developed and implemented an ultrasound training programme for diagnosing suspected GCA. We recruited 430 patients with suspected GCA. We analysed 381 patients who underwent both ultrasound and biopsy within 10 days of starting treatment for suspected GCA and who attended a follow-up assessment (median age 71.1 years; 72% female). The sensitivity of biopsy was 39% [95% confidence interval (CI) 33% to 46%], which was significantly lower than previously reported and inferior to ultrasound (54%, 95% CI 48% to 60%); the specificity of biopsy (100%, 95% CI 97% to 100%) was superior to ultrasound (81%, 95% CI 73% to 88%). If we scanned all suspected patients and performed biopsies only on negative cases, sensitivity increased to 65% and specificity was maintained at 81%, reducing the need for biopsies by 43%. Strategies combining clinical judgement (clinician's assessment at 2 weeks) with the tests showed sensitivity and specificity of 91% and 81%, respectively, for biopsy and 93% and 77%, respectively, for ultrasound; cost-effectiveness (incremental net monetary benefit) was £485 per patient in favour of ultrasound with both cost savings and a small health gain. Inter-rater analysis revealed moderate agreement among sonographers (intraclass correlation coefficient 0.61, 95% CI 0.48 to 0.75), similar to pathologists (0.62, 95% CI 0.49 to 0.76). LIMITATIONS There is no independent gold standard diagnosis for GCA. The reference diagnosis used to determine accuracy was based on classification criteria for GCA that include clinical features at presentation and biopsy results. CONCLUSION We have demonstrated the feasibility of providing training in ultrasound for the diagnosis of GCA. Our results indicate better sensitivity but poorer specificity of ultrasound compared with biopsy and suggest some scope for reducing the role of biopsy. The moderate interobserver agreement for both ultrasound and biopsy indicates scope for improving assessment and reporting of test results and challenges the assumption that a positive biopsy always represents GCA. FUTURE WORK Further research should address the issue of an independent reference diagnosis, standards for interpreting and reporting test results and the evaluation of ultrasound training, and should also explore the acceptability of these new diagnostic strategies in GCA.

Abstract
INTRODUCTION Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). We evaluated the effect of concomitant methotrexate (MTX) or glucocorticoid (GC) use on tofacitinib clinical efficacy. METHODS Data were pooled from two open-label, long-term extension studies of tofacitinib 5 or 10 mg twice daily in patients with RA. Response according to Clinical Disease Activity Index (CDAI) was assessed separately in patients who discontinued (no MTX/GC use within 30 days prior to year-3 visit; assessment at month 3/year 3) or initiated (on/before year 3; assessment at initiation and year 3) MTX/GC. RESULTS By year 3, among patients receiving background MTX at baseline, 186/1608 (11.6%) discontinued MTX, and 319/1434 (22.2%) patients receiving GC at baseline discontinued GC. Overall, 70.4/69.1% of patients who discontinued/continued MTX and 72.7/65.9% who discontinued/continued GC achieved CDAI remission or low disease activity (LDA) at year 3. Month 3 remission/LDA rates were maintained at year 3 in the majority of patients, irrespective of MTX/GC discontinuation/continuation. By year 3, 6.2% of patients receiving tofacitinib without MTX at baseline had initiated concomitant MTX, and 25.1% receiving tofacitinib without GC initiated GC; 69.0% and 45.4% initiating MTX or GC, respectively, had a CDAI-defined incomplete response prior to initiation. RA signs/symptoms improved following MTX initiation; only modest improvement was observed with GC initiation. CONCLUSIONS Patients achieving remission/LDA with tofacitinib may discontinue MTX or GC and maintain treatment response. Patients with an incomplete response may benefit from adding concomitant MTX.

Abstract
Background Early and intensive targeted treatment with disease modifying anti-rheumatic drugs (DMARDs) has been shown to lead to substantial reductions in disease activity and radiograph damage in patients with early rheumatoid arthritis (RA). The aim of this quasi-experimental study was to compare the first-year radiographic progression rates between a treat-to-target (T2 T) strategy with initial combination therapy (strategy II, started in 2012) versus an initial step-up monotherapy (strategy I, started in 2006). Methods A total of 128 patients from strategy II was individually matched with 128 patients from strategy I on sex, age (± 5 yrs.) and baseline disease activity (± 0.5 on the DAS28). Differences in radiographic progression (Sharp/van der Heijde) scores (SHS) and the number of patients experiencing a minimal clinically important difference (MCID; ≥ 5 SHS points) between both strategies were tested with Mann Whitney U and chi-square tests. Next, linear and logistic regression analyses were performed to examine which baseline variables were associated with radiographic progression scores and the probability of experiencing an MCID within 1 year. Results Patients with initial combination therapy had slightly higher baseline disease activity scores and pain scores, but better mental health scores. Patients with initial monotherapy had significantly more, and more frequently clinically relevant, radiographic progression after 1 year. Experiencing a MCID was independently associated with fewer tender joints (p = 0.050) and higher erythrocyte sedimentation rate (p = 0.015) at baseline. Conclusion Treating early RA patients with initial combination therapy results in better radiographic outcomes than initial monotherapy in daily clinical practice.

Impact of cumulative exposure to high-dose oral glucocorticoids on fracture risk in Denmark: a population-based case-control study. Arch Osteoporos 2018; 13:30.

Abstract
UNLABELLED We examined the effect of cumulative exposure to high doses of oral glucocorticoids on fracture risk. Compared to short-course users (daily dose ≥ 15 mg + cumulative < 1 g), heavy users (daily dose ≥ 15 mg + cumulative dose ≥ 1 g) had the highest risk of fracture. These patients should be monitored for fracture management strategies. PURPOSE The effect of cumulative exposure to high daily doses of oral glucocorticoids on fracture risk remains debated. We therefore aimed to examine the hip fracture risk associated with short courses and heavy use of high-dosed oral glucocorticoids. METHODS We conducted a population-based case-control study using the Danish National Health Service data, 1996-2011. Cases were those aged ≥ 18 years who sustained a hip (primary outcome) fracture (n = 81,342). Vertebral and forearm fractures were considered in secondary analyses. Controls (matched 1:1) were those without a fracture. Average daily dose (DD) and total cumulative dose (CD) were calculated among current oral glucocorticoid users. Among patients with a high daily dose (DD ≥ 15 mg), we identified short-course users as those with a CD < 1 g and heavy users as those with a CD ≥ 1 g. We estimated adjusted odds ratio (adj.OR) of fracture with current glucocorticoid use compared to never-use, using conditional logistic regression. RESULTS A high DD (≥ 15 mg) and high CD (≥ 1 g) were independently associated with an increased hip fracture risk (adj.OR 2.5; 95% CI 2.2-2.9; adj.OR 1.6; 95% CI 1.5-1.8, respectively). However, the risk was substantially increased among heavy users (DD ≥ 15 mg and CD ≥ 1 g: adj.OR 2.9; 95% CI 2.5-3.4) as compared to short-course users (DD ≥ 15 mg and CD < 1 g: adj.OR 1.4; 95% CI 1.1-1.9). Associations were stronger for vertebral fractures, yet little association was identified for forearm fractures. CONCLUSION Among patients receiving a high DD (≥ 15 mg), heavy users (≥ 1 g CD) showed the most substantial increase in hip fracture risk. Among those receiving high DD, a threshold of 1 g CD may identify heavy users that are candidates for focused fracture management services.

Abstract
The dissociated agonists of the glucocorticoid receptor are a novel class of agents in clinical development for rheumatoid arthritis. PF‐04171327 (fosdagrocorat) is a phosphate ester prodrug of PF‐00251802 (dagrocorat), a selective high‐affinity partial agonist of the glucocorticoid receptor, which is further metabolized to PF‐04015475. This study evaluated the cytochrome P450 (CYP)–mediated drug–drug interaction (DDI) potential of PF‐00251802 and PF‐04015475 in vitro and used model‐based prediction approaches to estimate clinical impact. PF‐00251802 is a reversible inhibitor of several CYPs, but modeling has suggested no clinically relevant interaction. PF‐00251802 and PF‐04015475 are time‐dependent inhibitors and inducers of CYP3A in vitro; PF‐00251802 is also a time‐dependent inhibitor of CYP2D6. Model‐based prediction suggested the potential for weak inhibition of CYP3A in vivo. A clinical DDI study was conducted with midazolam, a sensitive CYP3A substrate. A phase 1 open‐label, multiple‐dose study evaluated the effect of PF‐04171327 on midazolam pharmacokinetics and safety in 12 healthy volunteers. Administration of midazolam alone or concomitantly with PF‐04171327 resulted in equivalent pharmacokinetic profiles (AUCinf, 21.17 vs 20.28 ng·h/mL, respectively), indicating that PF‐04171327 had no net effect on CYP3A activity in vivo. These findings support the further development of PF‐00251802 and PF‐04171327 as potential treatments for patients with rheumatoid arthritis (NCT00987038).

Abstract
Abstract
Objectives
To estimate the prevalence of impaired morning function (IMF) in rheumatoid arthritis (RA), and to understand physicians’ and patients’ perceptions on the impact of IMF and treatment in selected Asian countries.
Methods
A survey on the impact of IMF was conducted in Asia on rheumatologists and patients with moderate-to-severe RA who experienced IMF for ≥3 mornings a week. Participants underwent comprehensive face-to-face interviews using structured questionnaires.
Results
Sixty physicians and 300 patients from Hong Kong, Philippines, Singapore, South Korea, and Taiwan were surveyed. Rheumatologists estimated that two-thirds of patients with RA experienced IMF and believed that the prevalence of IMF increased with RA severity (present in 42%, 73%, and 87% of patients with mild, moderate, and severe disease, respectively). Patients’ survey revealed that, on an average, patients with RA experienced IMF 5 days a week for 2 h each day. Thirty-eight percent of patients with RA considered a reduction in morning stiffness as an important treatment goal, but this was agreed by only 3% of rheumatologists. Only 22% of rheumatologists modified the treatment regimen specifically for IMF. Physicians considered prednisolone and other glucocorticoids (GCs) to be the most effective medication for the treatment of IMF. Fifty-one percent of patients with RA did not find their current medication effective in relieving IMF, and as a result, they reported negative emotions such as frustration, defeat, and anger, and 56% had missed work because of this symptom.
Conclusions
IMF is prevalent in RA and significantly affects patients’ quality of life (QoL). A higher proportion of patients compared to physicians view the reduction of morning stiffness as an important goal. More should be done to address the dissonance between physicians’ and patients’ views on IMF.

Abstract
The treatment of SLE remains complex, and management is constrained by a lack of safe, effective, targeted therapies. Physicians, also, are constrained by a lack of evidence-based approaches with existing agents, including glucocorticoids, utilized in the majority of patients. While Cushingoid side effects of glucocorticoids are widely recognized, emerging literature now suggests that glucocorticoid use actually contributes to harmful outcomes in SLE, over and above these effects. These studies provide a compelling case for a re-evaluation of the long-term use of glucocorticoids in SLE, focusing on minimizing glucocorticoid exposure as part of the strategy to improve long-term outcomes. In this article, we review the evidence for the harmful effects of glucocorticoids in SLE, and propose therapeutic options that reduce reliance on glucocorticoids. We propose that it is time for the lupus community to have a louder conversation about glucocorticoid use, and for any residual complacency about their risk-benefit ratio to be banished.

Abstract
ObjectiveTo explore the 7-year tolerability profile of glucocorticoids (GC) for early rheumatoid arthritis (RA).MethodsWe examined data for 602 patients with RA from the early arthritis Etude et Suivi des POlyarthrites Indifférenciées Récentes (ESPOIR) cohort (<6 months disease duration) stratified into two groups: with or without GC treatment at least once during follow-up (median 7 years (IQR 0.038–7.65)). The main outcome was a composite of death, cardiovascular disease (including myocardial ischaemia, cerebrovascular accident and heart failure), severe infection and fracture.ResultsAmong the 602 patients with RA (476 women (79%), mean age 48±12 years), 386 with GC (64.1%) received low-dose prednisone (mean 3.1±2.9 mg/day for the entire follow-up): 263 started GC during the first 6 months (68%), and the mean duration of total GC treatment was 1057±876 days. As compared with patients without GC (216 (35.9%)), those with GC showed greater use of non-steroidal anti-inflammatory drugs, synthetic and biological disease-modifying antirheumatic drugs and had more active disease disability, higher C reactive protein and anticitrullinated protein antibody levels. Among 65 events (7 deaths, 14 cardiovascular diseases, 19 severe infections and 25 fractures), 44 and 21 occurred in patients with and without GC (p=0.520). Infections were more frequent, although not significantly, in patients with than without GC (p=0.09). On weighted Cox proportional-hazards analysis, with use of propensity score and inverse-probability-of-treatment weighting, and including age, gender, history of hypertension and GC treatment, outcomes did not differ with and without GC (p=0.520; HR=0.889; 95% CI 0.620 to 1.273).ConclusionsThis 7-year analysis of the ESPOIR cohort supports the good safety profile of very low-dose GC for early active RA.

Abstract
To date, rheumatoid arthritis (RA) remains a debilitating, life-threatening disease. One major concern is morning symptoms (MS), as they considerably impair the patients’ quality of life and ability to work. MS change in a circadian fashion, resembling the fluctuations of inflammatory cytokines such as interleukin-6, whose levels are higher in RA patients compared to healthy donors. Conversely, serum levels of the potent anti-inflammatory glucocorticoid cortisol are similar to that of healthy subjects, suggesting an imbalance that sustains a pro-inflammatory state. From a therapeutic point of view, administering synthetic glucocorticoids (GCs) to RA patients represents an optimal strategy to provide for the inadequate levels of cortisol. Indeed, due to their high efficacy in RA, GCs remain a cornerstone more than 60 years after their first introduction, and despite the development of a wide range of targeted agents. However, to improve safety, low-dose GCs have been introduced, that have demonstrated high efficacy in reducing disease activity, radiological progression, and improving patients’ signs and symptoms especially in early RA when added to conventional disease-modifying antirheumatic drugs. A further improvement has been provided by the development of modified-release prednisone, which, by taking advantage of the circadian fluctuations of inflammatory cytokines, cortisol and MS, is given at bedtime to be released approximately 4 hours later. Several studies have already demonstrated the efficacy of this agent on disease activity, MS, and quality of life in the setting of established RA. Moreover, preliminary studies have shown that this new formulation not only has no impact on the adrenal function, but likely improves it. This review is a comprehensive, updated summary of the current evidence on the use of GCs in RA, with focus on the efficacy and safety of low-dose prednisone and modified-release prednisone, the latter representing a rational, cost-effective, and tailored approach to maximize the benefit/risk ratio in RA patients.

Comparative effectiveness of treatment with the first TNF antagonist in monotherapy, the first TNF antagonist plus one conventional synthetic disease-modifying antirheumatic drug, and the first TNF antagonist plus two or more conventional synthetic disease-modifying antirheumatic drugs in patients with rheumatoid arthritis. Arthritis Res Ther 2016; 18:259. [PMID: 27821150 PMCID: PMC5100281 DOI: 10.1186/s13075-016-1137-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2016] [Accepted: 09/26/2016] [Indexed: 11/16/2022] Open
Abstract
Background Rheumatoid arthritis (RA) patients are treated with a mean of 3–4 conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) with or without glucocorticoids (GCs), before the first biologic prescription. The main reasons for change are inefficacy in 30–40 % of patients, and toxicity ≈ 10 %. Thus, they are treated with the first TNF antagonists in monotherapy. The aim of this study was to analyse the csDMARD and GC prescription patterns before and during treatment with the first TNF antagonist, and compare their effectiveness in three groups of patients. Methods An observational, prospective, multicentre study in common clinical practice was designed. Treating rheumatologists recorded patient variables, including previous and concomitant csDMARDs and GCs in a database. The data were analysed using descriptive, inferential and multivariate statistics. Results There were 1136 patients included; 21 % received the first TNF antagonist in monotherapy, 67 % received the first TNF antagonist plus one csDMARD, and 12 % the first TNF antagonist plus two or more csDMARDs. Most patients were female (73 %), RF+, and ACPA+, and had erosions; mean age was 53.2 (±13.0) years, and duration of disease was 9.1 (±7.6) years. They had high activity with DAS28 of 5.8 ± 1.1, and poor physical function with HAQ of 1.43 ± 0.63, and significant differences between groups in clinical variables and comorbidities; 94 % had received treatment with GCs, MTX, LFN, or SSZ at any time before the first TNF antagonist, 5 % (n = 52) had been treated with CLQ or HCLQ, and 1 % (n = 13) had received neither GCs nor csDMARDs. Before the first TNF antagonist, the drugs most commonly used were GCs (78 %), MTX (50 %), LFN (44 %), and SSZ (21 %). Concomitantly with the first TNF antagonist, 977 patients (85 %) were receiving GCs, MTX, LFN, or SSZ; 15 % (n = 173) received their first TNF antagonist without any concomitant GCs or csDMARDs, true monotherapy, and 6 % received their first TNF antagonist with GCs. The drug most commonly used at the time of first TNF antagonist initiation was MTX (58 %). All treatment groups had clinically and statistically significant improvements in DAS and HAQ scores. Effectiveness analysis (controlling for confounders) showed mean drug survival of 16.7, 20.1 and 11.7 months in each group, respectively (p < 0.001). The model that best explained a good EULAR response included the baseline and 6-month DAS28. Conclusions The three groups of patiernts, have different comorbidities and disease characteristics. Treatment with low or very low doses of GCs is common. True monotherapy with the first TNF antagonist without prednisone or csDMARDs is infrequent. After controlling for potential confounders, effectiveness was a little different.

Abstract
Abstract
This article summarizes our approach to the management of children and adults with primary immune thrombocytopenia (ITP) who do not respond to, cannot tolerate, or are unwilling to undergo splenectomy. We begin with a critical reassessment of the diagnosis and a deliberate attempt to exclude nonautoimmune causes of thrombocytopenia and secondary ITP. For patients in whom the diagnosis is affirmed, we consider observation without treatment. Observation is appropriate for most asymptomatic patients with a platelet count of 20 to 30 × 109/L or higher. We use a tiered approach to treat patients who require therapy to increase the platelet count. Tier 1 options (rituximab, thrombopoietin receptor agonists, low-dose corticosteroids) have a relatively favorable therapeutic index. We exhaust all Tier 1 options before proceeding to Tier 2, which comprises a host of immunosuppressive agents with relatively lower response rates and/or greater toxicity. We often prescribe Tier 2 drugs not alone but in combination with a Tier 1 or a second Tier 2 drug with a different mechanism of action. We reserve Tier 3 strategies, which are of uncertain benefit and/or high toxicity with little supporting evidence, for the rare patient with serious bleeding who does not respond to Tier 1 and Tier 2 therapies.

Abstract
Philip Hench, Edward Kendall, and Tadeus Reichstein received the Nobel Prize in medicine and physiology in 1950 for their "investigations of the hormones of the adrenal cortex." Hench and Kendall took compound E from the laboratory to the clinic to the Nobel Prize in a span of 2 years. This article examines the paths that led to the day when the first rheumatoid arthritis patient received cortisone, and from there to the 1950 Nobel Prize ceremony. The aftermath of this achievement is also discussed. Although there have been significant advances in corticosteroid preparations and use since 1950, the side effects remain daunting.

Abstract
OBJECTIVE To determine the steroid-sparing effect of methotrexate (MTX) in patients with symptomatic generalized myasthenia gravis (MG). METHODS We performed a 12-month multicenter, randomized, double-blind, placebo-controlled trial of MTX 20 mg orally every week vs placebo in 50 acetylcholine receptor antibody-positive patients with MG between April 2009 and August 2014. The primary outcome measure was the prednisone area under the dose-time curve (AUDTC) from months 4 to 12. Secondary outcome measures included 12-month changes of the Quantitative Myasthenia Gravis Score, the Myasthenia Gravis Composite Score, Manual Muscle Testing, the Myasthenia Gravis Quality of Life, and the Myasthenia Gravis Activities of Daily Living. RESULTS Fifty-eight patients were screened and 50 enrolled. MTX did not reduce the month 4-12 prednisone AUDTC when compared to placebo (difference MTX - placebo: -488.0 mg, 95% confidence interval -2,443.4 to 1,467.3, p = 0.26); however, the average daily prednisone dose decreased in both groups. MTX did not improve secondary measures of MG compared to placebo over 12 months. Eight participants withdrew during the course of the study (1 MTX, 7 placebo). There were no serious MTX-related adverse events. The most common adverse event was nonspecific pain (19%). CONCLUSIONS We found no steroid-sparing benefit of MTX in MG over 12 months of treatment, despite being well-tolerated. This study demonstrates the challenges of conducting clinical trials in MG, including difficulties with recruitment, participants improving on prednisone alone, and the need for a better understanding of outcome measure variability for future clinical trials. CLASSIFICATION OF EVIDENCE This study provides Class I evidence that for patients with generalized MG MTX does not significantly reduce the prednisone AUDTC over 12 months of therapy.
