29985080 Predictive value of a multi-biomarker disease activity score for clinical remission and ra 2019 Jan OBJECTIVES: Measurement of serum biomarkers at disease onset may improve prediction of disease course in patients with early rheumatoid arthritis (RA). We evaluated the multi-biomarker disease activity (MBDA) score and early changes in MBDA score for prediction of 28-joint Disease Activity Score based on C-reactive protein (DAS28-CRP) remission and radiographic progression in the double-blinded OPERA trial. METHOD: Treatment-naïve RA patients (N = 180) with moderate or high DAS28 were randomized to methotrexate (MTX) + adalimumab (n = 89) or MTX + placebo (n = 91) in combination with glucocorticoid injection into swollen joints. X-rays of hands and feet were evaluated at months 0 and 12 (n = 164) by the total Sharp van der Heijde score (TSS). The smallest detectable change (1.8 TSS units) defined radiographic progression (∆TSS ≥ 2). Clinical remission (DAS28-CRP < 2.6) was assessed at baseline and 6 months. MBDA score was determined at 0 and 3 months and tested in a multivariable logistic regression model for predicting DAS28 remission at 6 months and radiographic progression at 1 year. RESULTS: Baseline MBDA score was independently associated with radiographic progression at 1 year [odds ratio (OR) = 1.03/unit, 95% confidence interval (CI) = 1.01-1.06], and changes in MBDA score from baseline to 3 months with clinical remission at 6 months [OR = 0.98/unit, 95% CI 0.96-1.00). In anti-cyclic citrullinated peptide antibody (anti-CCP)-positive patients, 35 of 89 with high MBDA score (> 44) showed radiographic progression (PPV = 39%), compared with 0 of 15 patients (NPV = 100%) with low/moderate MBDA score (≤ 44) (p = 0.003). CONCLUSION: Early changes in MBDA score were associated with clinical remission based on DAS28-CRP at 6 months. In anti-CCP-positive patients, a non-high baseline MBDA score (≤ 44) had a clinical value by predicting very low risk of radiographic progression at 12 months.
27455886 Oral Methotrexate in split dose weekly versus oral or parenteral Methotrexate once weekly 2018 May OBJECTIVE: To investigate whether methotrexate (MTX) administered orally to rheumatoid arthritis (RA) patients in split doses at 2-3 days' interval, would result in equal or better efficacy, tolerability and compliance, without increasing toxicity compared to single weekly dose given orally or parenterally. MATERIALS AND METHODS: One hundred and thirty-five patients fulfilling the American College of Rheumatology (ACR) 2010 criteria for RA, on 7.5 mg of MTX weekly orally, with the Simplified Disease Activity Index (SDAI) > 11 were enrolled for a 24-week period. Patients were randomly divided into three groups and were given MTX: Group 1 7.5 mg twice or thrice weekly orally, Group 2 15 mg or 22.5 mg in a single dose weekly orally and Group 3 15 mg or 22.5 mg in a single dose weekly as an intramuscular injection. The primary outcomes were low disease activity (LDA) and mean change in SDAI at week 24, whereas secondary outcomes included remission, adverse events and compliance. RESULTS: At week 24, adherence to treatment was maximum in Group 1, 69% (P = 0.09). In intention-to-treat analysis at 24 weeks, Group 1, 49%, Group 2, 36% and Group 3, 47% achieved LDA (P = 0.4). There was significant difference in mean change in SDAI at week 24 from baseline (P = 0.008) among the groups. Group 3 patients were more uncomfortable with the mode of administration of MTX (P = 0.003). There was no significant difference in adverse events. CONCLUSION: Oral split doses of MTX are better than an oral single dose and similar to parenteral MTX in terms of efficacy.
29340619 Recurrent serious infections in patients with rheumatoid arthritis-results from the Britis 2018 Apr 1 OBJECTIVES: To establish the rate of recurrent infection in RA patients recruited to the British Society for Rheumatology Biologics Register - Rheumatoid Arthritis. Secondary objectives were to establish whether the organ class of index infection predicted future serious infection (SI). METHODS: Using data from the British Society for Rheumatology Biologics Register - Rheumatoid Arthritis, a prospective observational cohort, we identified patients with at least one episode of SI. Incidence rates of SI, recurrent SI within the same organ class as the index infection and recurrent SI (of any class) were calculated. A Cox proportional hazards model was used to identify predictors of SI. RESULTS: In total, 5289 subjects with at least one SI contributing 19 431 patient-years follow-up were studied. The baseline annual rate of first SI was 4.6% (95% CI: 4.5, 4.7), increasing to 14.1% (95% CI: 13.5, 14.8) following an index infection. Respiratory infections were the most frequent (44% of all events). Recurrent infections mirrored the organ class of the index infection. Sepsis, increasing age and polypharmacy were significant predictors of infection recurrence in a fully adjusted model. The system class of index infection was associated with the risk of a recurrent event; subjects who experienced sepsis had the highest risk of subsequent SI within 12 months, 19.7% (95% CI: 15.1, 25.7). CONCLUSION: Recurrent infections in RA are common. Understanding patterns and predictors of recurrent infection together with the differential infection risk associated with immunosuppressive agents will help personalize RA care, tailor treatment choices better and mitigate against episodes of SI.
28652101 Salt, inflammatory joint disease, and autoimmunity. 2018 Jul Salt is a vital nutrient. Excess salt intake, however, has recently been blamed for triggering and/or worsening certain autoimmune diseases. In vitro, the cells involved in innate and adaptive immune responses exhibit an inflammatory profile when placed in hypertonic saline. More specifically, macrophages release increased amounts of proinflammatory cytokines, produce reactive oxygen species, and become capable of activating the inflammasome. T helper cells, via activation of serum and glucocorticoid-regulated kinase 1 (SGK1), overexpress IL-17A and IL-23R and differentiate into Th17 cells; whereas regulatory T cells lose the inhibitory capabilities needed to preserve self-tolerance. The data from animal models of autoimmune diseases and human patients are less consistent. SGK1 has been implicated in polarization toward the Th17 phenotype, which worsens conditions such as multiple sclerosis, systemic lupus erythematosus, autoimmune colitis, and transplant rejection. Observational epidemiological studies of patients with multiple sclerosis have demonstrated an association between excessive salt intake and a higher number of flares. Excessive salt intake is associated with a higher risk of developing rheumatoid arthritis, particularly in smokers. These data suggest that salt may stimulate certain immunological processes. Studies are therefore needed to assess the potential influence of dietary habits on the development and progression of autoimmune diseases.
29465355 Functional characterisation of ADP ribosylation factor-like protein 15 in rheumatoid arthr 2018 Jul OBJECTIVES: ARL15 is a novel susceptibility gene identified in a recent GWAS in a north Indian rheumatoid arthritis (RA) cohort. However, the role of ARL15 or ARF family genes in RA aetiology remains unknown. Therefore, we aimed to i) establish the expression of ARL15 in rheumatoid arthritis synovial fibroblasts (RASF) and ii) its functional characterisation by assessing its effects on major inflammatory cytokines and interacting partners using a knockdown approach. METHODS: RASF were cultured from synovial tissue obtained from RA patients (n=5) and osteoarthritis (OA) patients (n=3) serving as controls. Expression of ARL15, ARF1 and ARF6 in RASF was checked by semi-quantitative PCR and western blots; and altered expression of ARL15, if any, by induction of RASF with TNF using real-time PCR. The effect of ARL15 on the expression of adiponectin, adiponectin receptor I, IL6 and GAPDH and on cell mobility by invasion and migration assays were assessed by siRNA mediated gene knockdown. RESULTS: Expression of ARL15, ARF1 and ARF6 was confirmed in RASF and OASF samples but ARL15 expression remained unaltered on TNF induction. Notably, ARL15 knockdown resulted in downregulation of IL6 and GAPDH, upregulation of adiponectin and adiponectin receptor I genes; and significant reduction in migration and invasion of RASF. Genemania showed significant interactions of ARL15 with genes responsible for insulin resistance and phospholipase D. CONCLUSIONS: This first report on ARL15 expression in RASF and its likely role in inflammation and metabolic syndromes through a TNF independent pathway, encourages hypothesis-free studies to identify additional pathways underlying RA disease biology.
30007080 Health-related quality of life in women with endometriosis, compared with the general popu 2018 Nov INTRODUCTION: Women with endometriosis have reduced health-related quality of life (HRQoL). However, comparisons to the general population and other patient groups are lacking. MATERIAL AND METHODS: The present cross-sectional questionnaire study included 157 women with endometriosis, 156 women from the general population, and 837 women with rheumatoid arthritis (RA). During a period from 2012 to 2013, women aged 18-45 years were recruited from the Norwegian Endometriosis Association and from a random sample of women residing in Oslo, Norway. HRQoL data from women with RA were included from a survey conducted in 2009 among patients of the Oslo Rheumatoid Arthritis Register. The Short Form-36 (SF-36) questionnaire was used to measure HRQoL. RESULTS: Compared with the control group, the endometriosis group had significantly reduced mean scores for all SF-36 scales. The difference was largest for the scale bodily pain with a mean score of 47.6 in the endometriosis group vs 81.5 in the control group. Compared with the RA group, the endometriosis group had significantly reduced mean scores for the three SF-36 scales vitality, social functioning, and mental health. The mean scores of these scales in the endometriosis group were 33.4, 62.7, and 66.3, respectively, vs 42.7, 68.8, and 72.6 in the RA group. CONCLUSIONS: Women with moderate to severe endometriosis seem to have overall impaired HRQoL compared with women from the general population, and poorer mental HRQoL compared with women with RA.
28704126 Economic impact of adalimumab treatment in Japanese patients with rheumatoid arthritis fro 2018 Jan OBJECTIVES: The objective of this study is to evaluate the economic impact of adalimumab (ADA) on Japanese rheumatoid arthritis (RA) patients. METHODS: ANOUVEAU was a 48-week multicenter, prospective, observational, single-cohort study. Work-related outcomes including absenteeism, presenteeism, overall work impairment (OWI), and activity impairment (AI) were evaluated using the RA-related work productivity and activity impairment (WPAI/RA). The amount of productivity loss was estimated via multiplication of absenteeism, presenteeism and OWI by the national average occupational wage for paid worker (PW) and part time worker (PTW), and via multiplication of AI by the estimated wage for domestic work for home maker (HM). RESULTS: In this analysis, 1196 patients were included. At week 48, measures of productivity loss due to absenteeism, presenteeism, OWI, and AI were significantly improved by administrating ADA to RA patients in all employment types (PW, PTW, and HM), compared to baseline (p < .01). Productivity loss of Japanese society by RA disease was estimated to be $9.80 billion. The annual decrease in productivity loss through ADA administration to Japanese RA patients was estimated to be $3.76 billion. CONCLUSIONS: The socioeconomic burden of RA is high, but ADA treatment may reduce productivity loss related to RA.
29526711 Unmasking Fucosylation: from Cell Adhesion to Immune System Regulation and Diseases. 2018 May 17 Fucosylation is a biological process broadly observed in vertebrates, invertebrates, plants, bacteria, and fungi. Fucose moieties on cell-surface glycans are increasingly recognized as critical to many cell-cell interaction and signaling processes. One of the characteristic roles of fucose is its regulation of selectin-dependent leukocyte adhesion that has been well studied over the last two decades. Recent studies of fucose in immune cell development and function regulation have significantly expanded the contemporary understanding of fucosylation. From cellular adhesion to immune regulation, herein we discuss the use of gene knockout studies, competitive inhibitors of fucose-containing glycan, and metabolic inhibitors of fucose biosynthesis to probe fucosylated glycan biosynthesis and signaling and its functional consequences. Promising clinical and preclinical applications in sickle cell disease, rheumatoid arthritis, tumor inhibition, metastasis prevention, antibody-dependent cell-mediated cytotoxicity, chemoresistance reversal, and in improving chemotherapy-related side effects and recovery are reviewed.
30516323 Nurse telephone education for promoting a treat-to-target approach in recently diagnosed r 2019 Mar OBJECTIVE: The aim of the present study was to implement a nurse telephone education programme for patients with recently diagnosed rheumatoid arthritis (RA) that promotes shared decision-making and a treat-to-target approach. METHODS: This was a pilot project of newly diagnosed adult RA patients conducted between November 2015 and December 2016. A rheumatology clinic nurse telephoned patients to offer disease education. A toolkit was mailed to patients. Measures included call attempts, call time, a qualitative description of free-text notes and the proportion of patients who adhered to their next clinic visit. Data were analysed descriptively and qualitatively. RESULTS: Twenty-six patients participated in the nurse calls. Most patients were female (65%), with a median age of 54 years (range 22-78 years). Median call length was 14.5 min, with a range of 8-23 min. Qualitative notes indicated that patients overwhelmingly supported the nurse calls. Nineteen patients (73%) were adherent to their follow-up visit. CONCLUSION: This preliminary project successfully implemented an educational programme that included a nurse-facilitated, RA-specific, telephone call and toolkit. This educational programme could be a model for similar educational efforts by other clinics.
29875096 Health-related quality of life in patients with psoriatic and rheumatoid arthritis: data f 2018 Sep OBJECTIVES: To compare (1) Short Form-36 (SF-36) Physical Component Summary (PCS) and Mental Component Summary (MCS), scale scores and Short Form-6 dimensions (SF-6D) between patients with rheumatoid arthritis (RA) and patients with psoriatic arthritis (PsA) and Norwegian general population controls and (2) improvements in these measures between patients with RA and PsA. METHODS: Analyses of covariance were performed to compare SF-36 measures between first-time enrolled patients with RA (n=3898) and PsA (n=1515) from the prospective observational multicentre NORwegian-Disease Modifying Anti-Rheumatic Drug study (6 months follow-up) and general population controls (n=2323). RESULTS: In age and gender-adjusted analyses, patients with PsA compared with patients with RA had similar PCS, MCS and SF-6D (p≥0.14), worse vitality and general health, but better physical functioning at 0/6 months (p≤0.03). With additional 28-joint disease activity scores adjustment as a proxy for joint inflammation, PCS, most scale scores and SF-6D were worse in patients with PsA than patients with RA at 0/3/6 months (p≤0.01). PCS was more impaired than MCS both in RA and PsA compared with general population controls (p≤0.001). Mean 3-month and 6-month improvements after disease-modifying anti-rheumatic drug treatment were larger in patients with RA than patients with PsA for bodily pain, vitality and mental health (p≤0.02). CONCLUSIONS: Health-related quality of life was overall similar in patients with RA and patients with PsA-with a tendency to worse scores in PsA-and worse compared with Norwegian general population controls.
29648684 Inhibitory Receptor Expression on T Cells as a Marker of Disease Activity and Target to Re 2018 Sep OBJECTIVE: Inhibitory receptors are essential for the regulation of effector immune responses and may play critical roles in autoimmune diseases. We evaluated whether inhibitory receptor expression on T cells from patients with rheumatoid arthritis (RA) were correlated with immune activation, disease activity, and response to treatment, as well as whether inhibitory receptor-mediated pathways were functional. METHODS: Using flow cytometry, we performed extensive phenotypic and functional evaluation of CD4+ and CD8+ T cells from the blood and synovial fluid (SF) of RA patients ex vivo and after culture. The relationship of each parameter with the Disease Activity Score in 28 joints using the erythrocyte sedimentation rate (DAS28-ESR) and response to treatment was examined. RESULTS: In RA patients with low levels of T cell activation, inhibitory receptor expression showed an inverse relationship with the DAS28-ESR. The frequency of T cells expressing multiple inhibitory receptors was reduced in untreated RA patients but returned to normal levels in treated patients. RA patients who responded to treatment showed an augmented frequency of inhibitory receptor-expressing T cells that correlated with reduced inflammatory cytokine production in comparison to nonresponders. Higher frequencies of effector and memory T cells that expressed multiple inhibitory receptors were seen in SF than in peripheral blood. Notably, inhibitory pathways were operative in blood and synovial T cells from all RA patients, although cells from nonresponder patients were less sensitive to inhibition. CONCLUSION: Inhibitory receptor expression on T cells from RA patients is inversely correlated with effector T cell function and disease activity and may predict response to treatment. Furthermore, different inhibitory pathways are functional and cooperatively suppress synovial T cells, providing a rationale for new treatment strategies to regulate acute local inflammation.
29120821 An injectable, electrostatically interacting drug depot for the treatment of rheumatoid ar 2018 Feb To the best of our knowledge, no studies have yet examined the electrostatic interaction of polyelectrolytes with electrolyte drugs for the treatment of rheumatoid arthritis (RA). Here, an injectable, electrostatically interacting drug depot is described. We prepared methoxy polyethylene glycol-b-poly(ε-caprolactone)-ran-poly(l-lactic acid) (MC) diblock copolymers with a carboxylic acid group (MC-C) at the pendant position. MC-C was polyelectrolytes that exhibited negative zeta potentials. Sulfasalazine [Sul(-)] and minocycline [Min(+)], electrolyte RA drugs, exhibited negative and positive zeta potentials, respectively. The electrolyte RA drugs were loaded into the polyelectrolyte MC-C solution to prepare injectable, electrostatically interacting depot formulations. The formulation with an attractive electrostatic interaction [Min(+)-MC-C] exhibited gradual release of Min(+) from the MC-C depot over an extended period and suppressed the growth of inflammatory RAW 264.7 cells without affecting synovial cells. Mature chondrocytes were observed after H&E and safranin O staining of the cartilage of Min(+)-MC-C intra-articularly injected RA-induced rats. In comparison with other formulations, Min(+)-MC-C induced the suppression of the expression of pro-inflammatory proteins TNF-α and IL-1β in the articular knee joint, which resulted in the amelioration of RA. In conclusion, an injectable, electrostatically interacting depot formulation administered through intra-articular injection successfully provided almost complete amelioration of RA.
30553231 Cranberry juice decreases disease activity in women with rheumatoid arthritis. 2019 Apr OBJECTIVES: Studies have shown that cranberry (Vaccinium macrocarpon) has antiinflammatory and antioxidant effects; however, to our knowledge, the effects of cranberry juice consumption have not been studied in patients with rheumatoid arthritis (RA). The aim of this study was to verify the effect of cranberry juice consumption on several inflammatory biomarkers and on the disease activity of patients with RA. METHODS: A prospective study was conducted with 41 women diagnosed with RA. The disease activity measured by Disease Activity Score 28 (DAS28) and anticyclic citrullinated peptide (anti-CCP) antibodies, and several inflammatory and biochemical biomarkers were analyzed. The control group (n = 18) maintained their usual diet. The cranberry group (n = 23) consumed 500 mL/d of low-calorie cranberry juice. RESULTS: Regarding the baseline values, the cranberry group presented a decrease in the values of DAS28 (P = 0.048) and anti-CCP (P = 0.034) after 90 d of treatment, whereas changes in inflammatory biomarkers were not found. CONCLUSION: The present study indicated that cranberry juice decreases disease activity and therefore has beneficial effects for RA patients, although larger and long-term studies are needed to definitively probe this effect and to clarify the mechanisms involved.
30188218 Circulating Levels of Osteoprotegerin, Osteocalcin and Osteopontin in Patients with Rheuma 2019 Feb OBJECTIVE: Currently published data regarding the potential role of osteoprotegerin (OPG), osteocalcin (OCN) and osteopontin (OPN) for the discrimination between rheumatoid arthritis (RA) and osteoarthritis (OA) are contradictory. To derive a more precise evaluation, a meta-analysis was performed. METHODS: Published literatures comparing plasma/serum OPG, OCN and OPN levels between RA group and OA controls were searched in PubMed, Embase and the Cochrane Library. The Newcastle-Ottawa Scale was used to assess the study quality. Pooled standard mean difference (SMD) with 95% confidence interval (CI) was calculated by random-effect model analysis. Heterogeneity test was performed by the Q statistic and quantified using I(2). RESULTS: Nine studies including 438 RA patients and 255 OA patients were finally incorporated in the meta-analysis after examining title, type, abstracts and full text. The results showed that RA patients had higher plasma/serum OPN (pooled SMD = -2.57, 95% CI = -4.72 to -0.41) levels when compared to OA patients. No significant difference in plasma/serum OPG (pooled SMD = -0.29, 95% CI = -1.07‒0.49) and OCN (pooled SMD = -0.09, 95% CI = -0.48‒0.31) levels were found between RA patients and OA patients. Subgroup analysis indicated that plasma/serum OPG levels had no significant differences between RA patients and OA patients in Europe and Asian. CONCLUSIONS: Overall, there is no significant difference in circulating OPG and OCN levels between RA patients and OA patients. However, plasma/serum OPN level is significantly higher in RA patients compared with OA patients.
29892977 Circulating serum miR-223-3p and miR-16-5p as possible biomarkers of early rheumatoid arth 2018 Sep Small non-coding RNAs have emerged as possible biomarkers for various diseases including autoimmune diseases. A number of studies have demonstrated that the expression of specific microRNAs (miRNAs) is dysregulated in rheumatoid arthritis (RA). So far, all studies on miRNAs in RA patients have been performed using either microarray or reverse transcription-quantitative polymerase chain reaction (RT-qPCR) analyses. Compared to RT-qPCR and microarray analyses, next-generation sequencing (NGS) allows the genome-wide analysis of small RNAs and the differentiation between miRNAs that differ by a single nucleotide. The application of NGS to the analysis of small RNAs circulating in sera of RA patients has not been reported. This study provides a global overview of the circulating small RNAs in the sera of RA patients and healthy subjects and identifies differences between these groups using NGS. Several classes of small RNAs, including hY RNA-derived fragments, tRNA-derived fragments and miRNAs, were determined. Differentially expressed individual small RNAs were verified by RT-qPCR. The levels of two miRNAs, miR-223-3p and miR-16-5p, were significantly lower in the sera from early RA patients than in those from established RA patients and healthy controls. In contrast, the serum level of miR-16-5p was higher in patients with established RA than in healthy control samples. These miRNAs may not only serve as biomarkers, but may also shed more light on the pathophysiology of RA.
29246530 Controversies in rheumatoid arthritis glucocorticoid therapy. 2018 Jul Despite therapeutic innovations in the past 20 years, glucocorticoids (GC) are still widely used for the symptomatic treatment of rheumatoid arthritis (RA). Studies have demonstrated the clinical and structural efficacy of moderate doses (i.e. 30-60 mg/d) GC in addition to disease modifying anti-rheumatic drug (DMARD) initiation in early RA. A combination of a low dose of GC (i.e. 7.5-10 mg/d) and DMARDs increases remission rates and decreases the risk of medium-term structural progression in early RA. Intravenous and intramuscular administration of GC associated with DMARD initiation or intra-articular GC injections in symptomatic joints in tight control strategies increase remission rates in early RA. However, due to the risk of adverse events such as infections, cardiovascular events, or increased mortality induced by long-term use of GC, even at low-doses (e.g. 5 mg/d), GC should be prescribed at a minimal dose, for the shortest possible duration, and in association with DMARD initiation in early RA or DMARD change in active established RA.
30511527 [Expression of leukocyte immunoglobulin-like receptor A3 in CD14(+) monocytes of patients 2018 Feb 25 OBJECTIVE: To investigate the expression of leukocyte immunoglobulin-like receptor A3 (LILRA3) in CD14(+) monocytes of patients with rheumatoid arthritis (RA). METHODS: Fifty three RA patients admitted in the Second Affiliated Hospital of Zhejiang University School of Medicine from February 2017 to August 2017, and 21 healthy subjects were enrolled in the study. The expression of LILRA3 in CD14(+) monocyte subset was determined by flow cytometry, and its correlations with clinical features, laboratory examination results, antibodies and disease activity were analyzed. RESULTS: LILRA3 percentage in the CD14(+) monocyte subset of RA patients was higher than that in the healthy controls (P<0.01). The percentage of LILRA3 was positively correlated with number of tenderness joints, number of swollen joints and erythrocyte sedimentation rate (r=0.280, 0.371, 0.341, P <0.05 or <0.01), but was not correlated with the age, course of disease, Sharp score, C reactive protein, blood routine index and immunoglobulin (all P>0.05). In addition, the percentages of LILRA3 in the monocytes of rheumatoid factor (RF)-positive or anti-cyclic citrullinated peptide (CCP) antibody-positive patients were significantly higher than those of the RF-or anti-CCP antibody-negative patients (all P < 0.05); and the percentage of LILRA3 in patients with DAS28>5.1 was higher than that in patients with DAS28 ≤ 5.1 (P<0.05). CONCLUSIONS: The expression of LILRA3 is up-regulated in CD14(+) monocyte subset isolated from RA patients, and it is correlated with disease activity.
30119161 Hand functions in systemic lupus erythematosus: a comparative study with rheumatoid arthri 2018 Aug 16 BACKGROUND/AIM: Systemic lupus erythematosus (SLE) frequently affects the small joints of the hand and may result in difficulty in activities of daily living. There are very few studies evaluating the problems encountered in the hands in patients with SLE. The aim of this study is to evaluate hand functions in patients with SLE and compare them with rheumatoid arthritis (RA) patients and healthy subjects. MATERIALS AND METHODS: A total 46 female patients meeting the SLE classification criteria were recruited. Similarly, 51 female RA patients and 46 healthy female subjects served as the control groups. To assess the upper extremity disability level, the Disability Arm Shoulder and Hand Questionnaire (DASH) was used. Some functional performances such as hand grip and pinch strength were evaluated using a dynamometer and the Nine Hole Peg Test (NHPT), respectively. RESULTS: Hand functions were found to be impaired in both SLE and RA patients when compared to healthy controls. In addition, patients with SLE showed better performance in the NHPT, hand grip, and pinch strength than RA patients (P < 0.05). However, the patient-reported disability level was similar in both patient groups (P > 0.05). CONCLUSION: Similar to patients with RA, hand functions are significantly impaired in patients with SLE in daily activities.
28673829 Lumbar spine surgery in patients with rheumatoid arthritis (RA): what affects the outcomes 2018 Jan BACKGROUND CONTEXT: Although the cervical spine is only occasionally involved in rheumatoid arthritis (RA), involvement of the lumbar spine is even less common. A few reports on lumbar spinal stenosis in patients with RA have appeared. Although disc space narrowing occurs in aging, postoperative adjacent segment disease (ASD) in patients with RA has not been subject to much analysis. PURPOSE: The objective of this study was to investigate differences in ASD and clinical outcomes between lumbar spinal decompression with and without fusion in patients with RA. STUDY DESIGN/SETTING: This is a retrospective comparative study. PATIENT SAMPLE: A total of 52 patients with RA who underwent surgery for lumbar spinal disorders were included. Twenty-seven patients underwent decompression surgery with fusion and 25 underwent decompression surgery alone. OUTCOME MEASURES: Intervertebral disc space narrowing and spondylolisthesis of the segment immediately cranial to the surgical site were measured using a three-dimensional volume rendering software. Pre- and postoperative evaluation of RA activity and Japanese Orthopaedic Association (JOA) scores were conducted. MATERIALS AND METHODS: All patients had preoperative and annual postoperative lumbar radiographs and were followed up for a mean of 5.1 years (range 3.5-10.9 years). Pre- and postoperative (2 years after surgery) JOA scores were recorded and any postoperative complications were investigated. Degrees of intervertebral disc narrowing and spondylolisthesis at the adjacent levels were evaluated on radiographs and were compared between the two groups. Analysis was performed to look for any correlation between ASD and RA disease activities. RESULTS: Postoperative JOA scores were significantly improved in both groups. The rate of revision surgery was significantly higher in the fusion group than that in the non-fusion group. The rate of ASD was significantly greater in the fusion group than that in the non-fusion group at the final follow-up examination. Both matrix metalloproteinase 3 (MMP-3) and the 28-joint disease activity score incorporating C-reactive protein levels (DAS28-CRP) were significantly associated with the incidence and severity of ASD. CONCLUSIONS: Adjacent segment disease and the need for revision surgery were significantly higher in the fusion group than those in the non-fusion group. A preoperative high MMP-3 and DAS28-CRP are likely to be associated with postoperative ASD.
29389689 A Development and Feasibility Study of a Peer Support Telephone Program in Rheumatoid Arth 2018 Sep OBJECTIVES: Describe the development and feasibility of a telephone peer support program that provides education, emotional support, and enhances coping skills among rheumatoid arthritis (RA) patients. METHODS: In an academic arthritis center, peer coaches received 5 training modules: 1) definition and expectations of peer coaching, 2) structure/management of phone calls, 3) confidentiality, 4) psychological techniques for encounters, 5) referral guidelines and resources. Follow-up, acceptability and comparison with patients receiving standard care included mean adjusted change differences at 6 months in fatigue, pain, self-efficacy, functional status (SF-12), flare frequency and medication adherence (ASK-20). RESULTS: Eighteen peer coaches were assigned on average, 1.7 (SD, 1.4) patients. They spoke 8.4 (SD, 7.2) times; 21 of 29 patients completed the program. The most common topics requested were how to manage flares, 10(48%), medical aspects of RA, 10(48%) and understanding how to live with RA, 9(43%). After 6 months, non-significant improvements occurred in study outcomes (largest changes SF-12 PCS (mean adjusted change (SE) intervention v. standard care, 4.7(2.6) v. 0.5(2.0)) and how RA impacts one’s life (1.8(6.4) v. −4.9(5.8)). Participants reported many benefits from peer support. They felt less alone, 13(62%), more part of a sharing community, 12(57%) and had a better understanding of RA, 9(43%). They felt calmer, 9(43%), less sad,5(24%) and that they had more support from family and friends, 5(24%). CONCLUSIONS: An RA telephone peer support program is feasible and acceptable to patients. While the study was underpowered to detect statistical improvements, patients reported benefits suggesting the need for randomized evaluation.
