31295280 | Metabolomic approach to the exploration of biomarkers associated with disease activity in | 2019 | We aimed to investigate metabolites associated with the 28-joint disease activity score based on erythrocyte sedimentation rate (DAS28-ESR) in patients with rheumatoid arthritis (RA) using capillary electrophoresis quadrupole time-of-flight mass spectrometry. Plasma and urine samples were collected from 32 patients with active RA (DAS28-ESR≥3.2) and 17 with inactive RA (DAS28-ESR<3.2). We found 15 metabolites in plasma and 20 metabolites in urine which showed a significant but weak positive or negative correlation with DAS28-ESR. When metabolites between active and inactive patients were compared, 9 metabolites in plasma and 15 in urine were found to be significantly different. Consequently, we selected 11 metabolites in plasma and urine as biomarker candidates which significantly correlated positively or negatively with DAS28-ESR, and significantly differed between active and inactive patients. When a multiple logistic regression model was built to discriminate active and inactive cohorts, three variables-histidine and guanidoacetic acid from plasma and hypotaurine from urine-generated a high area under the receiver operating characteristic (ROC) curve value (AUC = 0.8934). Thus, this metabolomics approach appeared to be useful for investigating biomarkers of RA. Combination of plasma and urine analysis may lead to more precise and reliable understanding of the disease condition. We also considered the pathophysiological significance of the found biomarker candidates. | |
31746145 | Sociodemographic factors as determinants of disease, disability and quality of life trajec | 2020 Jan | OBJECTIVE: This study aims to describe the association between sociodemographic factors and trajectories of disease, disability and health-related quality of life (HRQoL) in early rheumatoid arthritis (ERA). METHODS: Data were collected prospectively over 3Â years in the Singapore Early Arthritis Cohort study. Trajectories were modeled using multi-trajectory group-based trajectory modeling (GBTM) and determinants of trajectory membership were identified using multinomial logistic regression. RESULTS: Two hundred and thirteen patients were included: 58.2% Chinese, 16.4% Malay, 21.6% Indian, mean (SD) age 51.3 (12.6) years and symptom duration 21.8 (15.3) weeks. In the multi-trajectory analysis, three groups of disease trajectories and corresponding disability and HRQoL trajectories were identified: group 1 (moderate disease rapid response, 49.9%), group 2 (high disease rapid response, 31.1%) and group 3 (high disease slow response, 19.1%). Malay patients had higher relative risk ratio (RRR) of being in trajectory groups 2 and 3 compared to group 1 (RRRÂ =Â 2.30, 95% CI 1.05-3.98 and RRRÂ =Â 4.02, 95% CI 1.45-6.43, respectively) while patients with tertiary education had lower relative risk (RRRÂ =Â 0.56, 95% CI 0.45-0.89 and RRRÂ =Â 0.33, (95% CI 0.14-0.83, respectively). In the analysis of individual outcomes, ethnicity, education level and body mass index were determinants of the heterogeneous disease activity trajectories. Gender and education level were determinants of the disability trajectories. Only gender was a determinant of the HRQoL trajectories. Further, 96.2% of the patients were treated with conventional synthetic disease-modifying antirheumatic drugs. CONCLUSION: Disparities in sociodemographic factors should be taken into consideration in formulating treatment strategies in ERA. | |
29975014 | Natural Product Dietary Supplement Use by Individuals With Rheumatoid Arthritis: A Scoping | 2019 Jun | OBJECTIVE: Natural product dietary supplements (NDS), defined as non-mineral, non-vitamin, ingested, natural product-derived, substances, are the most frequently used complementary and alternative medicine modality in the US, with musculoskeletal disease being the most frequent reason for their use. Because NDS usage is frequently unreported, and patients with RA may be at higher risk for NDS-related side effects due the underlying nature of the disease and frequent use of complex pharmaceutical regimens, a scoping review of the literature was undertaken to examine population-based patterns of NDS use for RA self-management. METHODS: Using guidelines for scoping reviews, Allied and Complementary Medicine, the Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library, Embase, Ovid/Medline, and Web of Science databases were searched to identify references presenting primary data related to the prevalence or patterns of use of NDS in RA populations. RESULTS: Twenty-three studies, which were published between 1980 and 2015 and conducted in 11 countries, met the inclusion criteria. The overall prevalence of NDS use in patients with RA was 47% worldwide and did not differ by geographic region. On average, 47% of patients found NDS to be effective and 13% reported adverse side effects, with only 30% informing their physicians about the use of NDS, which in a majority of cases were used concomitantly with RA pharmaceuticals. Marine oils, glucosamine, vinegar, and chondroitin were among the most commonly reported NDS worldwide. CONCLUSION: Given the apparent communication gap between patients and providers regarding NDS use and higher potential risks associated with this usage in RA, ongoing surveillance of population-based practices may help facilitate RA management and direct future NDS research. | |
31322831 | Rheumatologists' insight into medication adherence in patients with rheumatoid arthritis: | 2019 Sep | BACKGROUND: Medication non-adherence is prevalent among patients with rheumatoid arthritis (RA). Rheumatologists are specialists in medication prescribing and counselling for RA, but their insights regarding medication adherence have not been studied. OBJECTIVE: To explore rheumatologists' insights into medication adherence in patients with RA. METHODS: A qualitative study using semi-structured interviews with 10 rheumatologists in Iran was undertaken. Thematic analysis was conducted to identify how rheumatologists assess medication adherence and their perceived determinants of adherence. The identified determinants of adherence were mapped according to the Andersen's Behavioral Model of Health Service Use. RESULTS: Six participants were male, and the mean age was 47Â years. The mean years of experience as a rheumatologist was 8.6 (SDÂ =Â 7.1) years. Rheumatologists did not use a validated tool for medication adherence assessment. They assessed medication adherence either by asking their patients simple questions or using laboratory test results. The identified determinants of adherence were divided into 3 groups: patient-, rheumatologist- and healthcare organization-related determinants. The proposed suggestions to improve adherence were: (a) to understand a patient's financial situation before prescribing more expensive medications; (b) to employ a dose-reducing strategy; (c) to give hope to patients regarding remission; and (d) to arrange a session with the nurse educator. CONCLUSION: The findings of this study provide insight into rheumatologists' perspectives on medication adherence of patients with RA. The identified determinants of adherence could be considered when developing initiatives to improve medication adherence in this group of patients. | |
31612755 | The periodontal inflamed surface area is associated with the clinical response to biologic | 2020 Nov | Objectives: We evaluated whether the periodontal inflamed surface area (PISA), a measure of the inflammatory burden posed by periodontitis, is associated with the clinical response to biological disease-modifying antirheumatic drugs (bDMARDs) in patients with rheumatoid arthritis (RA).Methods: We conducted a retrospective study that collected rheumatologic and periodontal data from 54 patients with RA who had received corticosteroid, conventional synthetic DMARDs, or non-steroidal anti-inflammatory drugs before (baseline) and after 6 months of bDMARD therapy. After the patients were divided into two groups based on high or low PISA according to the median measurements at baseline, the rheumatologic condition was compared between the groups.Results: The patients with a low PISA showed significantly lower values for the Clinical Disease Activity Index (CDAI) (p = .008), swollen joint count (p = .02), and patient's and evaluator's global assessment (p = .01 and p = .03) and significantly greater decreases in changes in the CDAI from baseline to 6 months than the patients with a high PISA (p = .01), although these values were comparable at baseline. Both univariate and multivariate analyses revealed a significantly positive correlation between the baseline PISA and changes in the CDAI (p = .04 and p < .001).Conclusion: The PISA is associated with the clinical response to bDMARDs in patients with RA. | |
30497868 | FRAX 10-yr Fracture Risk in Rheumatoid Arthritis-Assessments With and Without Bone Mineral | 2019 Jan | OBJECTIVES: FRAX is a computer-based algorithm developed by the World Health Organisation for estimation of the 10-yr risk of a hip or major osteoporotic fracture. Inclusion of femoral neck bone mineral density (BMD) in the estimation is optional. The study aimed to investigate the intra-individual agreement between FRAX fracture risk calculated with and without BMD in patients with rheumatoid arthritis (RA). METHODS: Clinical data and BMD results from 50 RA patients registered in the Danish rheumatology registry (DANBIO) were used for analysis. Using the Bland-Altman method, lower and upper 95% limits of agreement [LLoA;ULoA] between intraindividual assessments of fracture risk with and without BMD and the bias (mean of individual differences) were calculated. Categorization of patients according to the National Osteoporosis foundation (NOF) treatment thresholds were also assessed with and without BMD. RESULTS: Mean age was 63.6 ± 11.7 yr, mean disease activity score (DAS28-CRP) 3.3 ± 3.5 and mean femoral neck T-score -1.43 ± 1.15. The mean 10-yr risk of a major fracture and a hip fracture calculated with BMD was 22.9 ± 15.8% and 8.5 ± 10.8%, respectively. The LLoA and ULoA [bias] calculated without vs with BMD were -14.5 and 20.4 percent point (pp) [2.9 pp] for major fracture risk and -14.0 and 23.2 pp [4.6 pp] for hip fracture. NOF treatment categorization was only dependent on BMD in 4% of the patients. CONCLUSION: The FRAX fracture risk estimated with and without BMD may disagree substantially in individual patients with RA but this seems to have only little impact on treatment categorization based on the NOF guidelines. | |
30930349 | Chronic Nodular Pulmonary Aspergillosis in a Patient with Rheumatoid Arthritis. | 2019 | Chronic pulmonary aspergillosis, which features nodular lesions known as Aspergillus nodules, is a relatively uncommon disorder. We herein report a case of slowly progressing chronic multiple nodular pulmonary aspergillosis in a 59-year-old man with rheumatoid arthritis, dyspnea, and fatigue. One nodule was surgically resected. The surgical specimen featured central necrosis and was located adjacent to a respiratory bronchiole and pulmonary artery, without parenchymal invasion. Branching septate hyphae, compatible with Aspergillus, were seen inside this necrotic nodule. Chronic pulmonary aspergillosis should therefore be considered in the differential diagnosis of patients who present with slowly progressing pulmonary multiple nodules. | |
31482536 | Myocardial ischemia in female patients with rheumatoid arthritis assessed with single phot | 2019 | BACKGROUND: Non-specific cardiac symptoms in female patients with rheumatoid arthritis (RA) could indicate early cardiovascular disease. MATERIALS AND METHODS: Myocardial perfusion imaging (MPI), with 99mTc tetrofosmin stress-rest single photon emission computer tomography (SPECT), in 13 RA female patients with atypical cardiac symptoms, was compared to 44 weight- and age-matched females with similar cardiac complaints (control group). Smoking, hypertension, diabetes mellitus, dyslipidemia, obesity and cardiac heredity were recorded and compared between the study and control group. MPI was assessed using 17 segment polar map and with a scale of 0 to 5 scoring. RESULTS: Patients with RA demonstrated higher cardiovascular risk (46%) compared to control individuals (17%). In addition, patients with RA had more irreversible myocardial ischemic abnormalities in their MPI than the control group. Dyslipidemia and obesity was found more frequent in RA patients with MPI SSS ≥ 4. CONCLUSION: RA patients with atypical cardiac complaints are at higher risk for cardiovascular disease; early detection and monitoring of this patient group could potentially reverse or successfully manage the consequences of the upcoming cardiovascular disease. | |
31032342 | Gender Differences in Cardiovascular Risk Profile in Rheumatoid Arthritis Patients with Lo | 2019 | OBJECTIVE: Patients with rheumatoid arthritis (RA) have an excess risk of cardiovascular (CV) disease (CVD). The objective of the study was to compare CV risk profile in female and male RA patients with low disease activity. MATERIALS AND METHODS: The study group consisted of 70 RA patients with continuous low disease activity and no CVD (54 women, 16 men) and 33 healthy controls of comparable age. The groups were assessed for blood pressure, serum amino-terminal pro-brain natriuretic peptide (NT-proBNP), carotid intima media thickness (cIMT), electrocardiography, ejection fraction (EF), and diastolic dysfunction (DD). RESULTS: Significantly higher burden of atherosclerosis, as revealed by higher cIMT, was found in males [0.93 (0.2) mm] vs females [0.80 (0.2) mm]. The risk of 10-year CVD was significantly higher in men than in women with RA. High/very high risk of fatal CVD was found in 62.5% of male patients. Males were significantly more often current/ex-smokers and had lower HDL-cholesterol and higher atherogenic index. There were no significant differences in NT-proBNP, QTc duration, and parameters of EF and DD. CONCLUSIONS: In RA patients with continued low disease activity, a higher burden of atherosclerosis was found in males than in females. The data suggest a significant impact of traditional CV risk factors. | |
30478637 | Macrophage depletion with clodronate-containing liposomes affects the incidence and develo | 2019 Dec | OBJECTIVE: This study investigated the effect of macrophage depletion with clodronate-containing liposomes (Clo-lip) on the incidence and development of rheumatoid arthritis (RA). METHODS: The effect of macrophage depletion with Clo-lip in the spleen was assessed by HE (haematoxylin and eosin) staining and immunohistochemistry (IHC). Thirty BALB/c mice were randomly divided into three groups, which were administered PBS-lip, Clo-lip, or normal saline. RA model mice were then created and the appearance of the paws was observed. Expression of CD68 by macrophages was examined by immunofluorescence on the 49th day. Forty-five RA model mice were created and randomly divided into three groups. The experiment group was administered Clo-lip at different timepoints. The degree of arthritis score was recorded during the administration. Histological features were detected by HE staining on the 84th day. RESULTS: Compared to controls, horseshoe-shaped nuclei and multi-core large cells were reduced in the experimental group (HE stain; p < 0.05). Brown tag-CD68 and tag-CD80 macrophages were fewer in the experimental group than in the control group (immunohistochemistry; p < 0.05). Furthermore, the degree of arthritis score in the experimental group was significantly decreased (p < 0.05). HE staining showed that there was no or less inflammatory cell infiltration in the articular cavity in mice in the experimental group, and that the percentage of CD68(+) macrophage cells in synovial cells was significantly lower than in the control group (p < 0.05). CONCLUSION: Macrophage depletion with Clo-lip can affect the incidence and development of RA. | |
31615315 | Plasma pentraxin 3 is associated with progression of radiographic joint damage, but not ca | 2020 Nov | Background: Pentraxin 3 (PTX3) has an important role in inflammation, immunity, and atherosclerosis. Rheumatoid arthritis (RA) is a chronic inflammatory disease featuring both joint damage and atherosclerosis. We investigated whether the plasma PTX3 level was associated with progression of joint destruction and subclinical atherosclerosis in RA patients.Methods: Plasma PTX3 levels were measured in 72 women with RA and 80 female control subjects. In RA patients, we also evaluated clinical characteristics, medications, and at one and three years, joint damage and atherosclerosis. Then we investigated whether PTX3 was associated with progression of joint destruction or an increase of carotid intima-media thickness (IMT).Results: Plasma PTX3 levels were significantly higher in the RA patients than in healthy controls (4.05 ± 2.91 ng/mL vs. 1.61 ± 1.05 ng/mL, p < .001). By multivariate linear regression analysis, the plasma pentraxin 3 level was independently associated with radiographic progression of joint damage for 3 years in the RA patients after adjustment for age, disease duration, body mass index, rheumatoid factor, MMP-3, Disease Activity Score 28-ESR, postmenopausal status, current use of corticosteroids and biologic use. On the other hands, pentraxin 3 was not associated with an increase of carotid intima-media thickness in RA patients.Conclusion: Female RA patients had elevated plasma PTX3 levels compared with control female subjects. PTX3 was independently associated with radiographic progression of joint damage in the RA patients, but not with carotid atherosclerosis. | |
31147369 | Factors of importance for reducing fatigue in persons with rheumatoid arthritis: a qualita | 2019 May 29 | OBJECTIVE: Physical activity plays an important role in the treatment of persons with rheumatoid arthritis (RA) and is the non-pharmacological intervention with the strongest evidence to reduce fatigue. However, physical activity can be challenging for persons who are fatigued. The aim of this study was to investigate factors of importance for reducing fatigue in persons with RA. DESIGN: This is a qualitative interview study based on semistructured, indepth individual interviews. Interviews were analysed using qualitative content analysis. PARTICIPANTS: Participants were 12 people with RA recruited from a previous randomised controlled trial of a person-centred treatment model focusing on health-enhancing physical activity and daily balance to lessen fatigue in persons with RA. SETTING: Interviews were conducted in a hospital setting. RESULTS: The analysis resulted in one theme: an intellectual and embodied understanding that sustainable physical activity is important to handle fatigue. This included five categories describing barriers and facilitating factors for sustainable physical activity: mentally overcoming the fatigue in order to be active, making exercise easy, reaching for balance, receiving support to be physically active and dealing with RA disease to be physically active. CONCLUSION: The participants in this study expressed that physical activity was important in handling fatigue, but also that this insight could only come from personal experience. The use of a person-centred ethic in physiotherapy coaching for patients with fatigue appears to promote sustainable physical activity behaviours by facilitating patients' resources to overcome barriers to physical activity. | |
29916966 | Rates of Neuropsychological Dysfunction in Fibromyalgia and Rheumatoid Arthritis: An Autom | 2019 Sep | BACKGROUND/OBJECTIVE: Fibromyalgia (FM) is a chronic pain syndrome of unknown etiology that can include subjective cognitive symptoms and variable evidence of cognitive dysfunction. Rates of occurrence and severity of cognitive impairment remain unclear. Additionally, comparison of this group with other pain conditions has been limited. The current cross-sectional study sought to identify rates of clinically significant cognitive impairment in FM and rheumatoid arthritis (RA) using an automated clinical rating approach. METHODS: A total of 61 females (32 with FM, 29 with RA) completed a comprehensive neuropsychological (NP) battery and an assessment of personality and psychological distress. All study measures were completed in one visit and all participants were recruited over the span of 3 years. Demographically corrected NP scores were used to compare participants with normative expectations and a summary score was calculated to compare groups on NP impairment. RESULTS: Compared to normative expectations using a 1 standard deviation cutoff, moderately increased rates of cognitive deficits were observed in both groups (FM = 23.3%, RA = 34.5%), with most test scores in affected individuals falling in the mild to moderate ranges of impairment. Compared to RA, FM participants endorsed higher and significant levels of psychological symptoms overall. These were not associated with cognitive performance in either patient group. CONCLUSIONS: Increased rates of cognitive dysfunction as well as psychological distress exist in both FM and RA compared to a normative sample. However, psychological distress was unrelated to cognition in both groups. These findings have implications regarding the clinical presentation of individuals with FM and RA. | |
30323010 | Minimal Clinically Important Improvement of Routine Assessment of Patient Index Data 3 in | 2019 Jan | OBJECTIVE: To estimate minimal clinically important improvement (MCII) of RAPID-3 (Routine Assessment of Patient Index Data 3) in rheumatoid arthritis (RA). METHODS: RAPID-3 was computed before and after treatment escalation in a prospective study of adults with active RA. Patient judgment of improvement was used as the standard for a receiver-operating characteristic curve, from which MCII was estimated. RESULTS: Mean RAPID-3 improved from 16.3 to 11.1 between visits. MCII was -3.8 based on simultaneously optimized sensitivity and specificity, -3.5 using the 0.80 specificity criterion, and -4.1 using the Youden index. CONCLUSION: RAPID-3 improvement of 3.8/30 units appears clinically meaningful. | |
31278695 | Determining MRI Inflammation Targets When Considering a Rheumatoid Arthritis Treat-to-Targ | 2019 Sep | INTRODUCTION: Magnetic resonance imaging (MRI) is increasingly used in patients with rheumatoid arthritis (RA) to determine residual inflammation after treatment and as a predictor of structural damage progression. Establishing an optimal threshold of inflammatory activity that predicts lower risk of structural damage progression may inform treatment decisions. This post hoc analysis investigated whether patients with RA at low risk of structural damage progression can be identified based on MRI inflammation thresholds. METHODS: Hand and wrist MRI was performed at baseline, and at months 6 and 12 in a phase 3b, randomized, active-controlled, double-blind trial of abatacept in early RA (AVERT). Pathologies were scored using the OMERACT RA MRI Score. Data were stratified into two risk subgroups (less and more severe inflammation) for structural damage progression (erosion change > 0.5) based on baseline inflammation. In this post hoc analysis, log odds ratios of probability of progression {adjusted for baseline Disease Activity Score in 28 joints [C-reactive protein; DAS28 (CRP)]} were compared between subgroups to test the performance of inflammation thresholds. RESULTS: There were 351 randomized and treated patients with baseline MRIs, of whom 276 (78.6%) and 235 (67.0%) had MRIs available at months 6 and 12, respectively. The DAS28 (CRP)-adjusted probabilities of progression from baseline to month 12 based on scores at baseline, and from months 6 to 12 based on month 6 scores, were significantly lower among patients with less inflammation (P < 0.0001-0.0459), independent of clinical disease activity. Predefined thresholds of synovitis ≤ 3 (total score 21), osteitis ≤ 3 (total score 69) and total inflammation score (osteitis double-weighted) ≤ 9 were associated with a lower likelihood of structural damage progression in unadjusted analyses. CONCLUSION: Levels of MRI-determined inflammatory activity below defined thresholds were independently associated with a lower risk of structural damage progression in early RA, providing a potential trial endpoint for levels of inflammation not associated with progression. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT01142726. FUNDING: Bristol-Myers Squibb. | |
31595690 | Validity and reliability of the unsupported upper-limb exercise test in individuals with r | 2019 Nov | BACKGROUND: Rheumatoid arthritis (RA) is a chronic disease which affects the performance of the upper extremities. There is no method to evaluate the specific upper extremity endurance of individuals with this disease. The unsupported upper-limb exercise test (UULEX) is a performance test that evaluates upper extremity performance (functionality and endurance). AIM: The aim of this study was to examine the reliability and validity of UULEX and the minimal detectable change (MDC) in individuals with RA. METHODS AND MATERIALS: The study included 71 patients (15 male, 56 female) with a mean age of 52.15 ± 10.11 years. The intraclass correlation coefficient (ICC) was used to assess the reliability of UULEX. MDC estimates were calculated using baseline data. Correlations of UULEX with the Disability of Arm, Shoulder and Hand Questionnaire (DASH), Health Assessment Questionnaire (HAQ), 30-second push-up test and 6 pegboard ring test (6PBRT) were assessed for concurrent validity. RESULTS: The level, weight and duration scores of the UULEX test were found to be excellent for intra-rater reliability (ICC = 0.922, 0.960, 0.958). Intra-rater MDC values were determined to be 0.35, 2.04, and 0.80 seconds, respectively. Moderate-excellent correlations were found between UULEX and DASH, HAQ, 30-second push-up test and 6PBRT (P < .05). CONCLUSION: The results of this study showed that UULEX test is a valid and reliable method for the assessment of upper extremity performance in individuals with RA. | |
31209481 | Drug retention of biological DMARD in rheumatoid arthritis patients: the role of baseline | 2019 Dec 1 | OBJECTIVE: To examine the association of the evolution in physician-reported and patient-reported outcomes with decision to stop biological DMARDs (bDMARDs) in RA. The contribution of baseline characteristics is well established, but little is known about how the disease evolution influences the decision to discontinue therapy. METHODS: RA patients who initiated a bDMARD treatment from 2009 and with information on date of visit were pooled from seven European RA registers. Each outcome was divided into baseline assessments (capturing the inter-individual differences at drug initiation) and changes from baseline at subsequent visits (capturing the individual evolution). Cox regression models were used to examine their association with drug discontinuation, adjusting for baseline patient and co-therapy characteristics and stratifying by register and calendar year of drug initiation. RESULTS: A total of 25 077 patients initiated a bDMARDs (18 507 a TNF-inhibitor, 3863 tocilizumab and 2707 abatacept) contributing an amount of 46 456.8 patient-years. Overall, drug discontinuation was most strongly associated with a poor evolution of the DAS28, with a hazard ratio of 1.34 (95% CI 1.29, 1.40), followed by its baseline value. A change of Physician Global Assessment was the next strongest predictor of discontinuation, then the Patient Global Assessment. CONCLUSIONS: The decision to discontinue treatments appears to be mostly influenced by DAS28 and particularly its evolution over time, followed by Physician Global Assessment evolution, suggesting that the decision to stop bDMARDs relies more on the physician's than on the patient's global assessment. | |
31392560 | Comparison of sexual function in Tunisian women with rheumatoid arthritis and healthy cont | 2019 Dec | OBJECTIVES: To evaluate sexual function in Tunisian women with rheumatoid arthritis (RA) and to compare it with that in voluntary healthy controls. METHODS: We conducted a cross-sectional study including 71 women with a confirmed diagnosis of RA according to the American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) 2010 Criteria and 71 healthy age-matched controls. Clinical and sociodemographic characteristics were collected. Patients and controls were asked to complete the Female Sexual Function Index (FSFI). It contains 19 questions, assessing six areas of female sexual function in the previous 4 weeks. The sexual dysfunction was defined as an FSFI score less than or equal to 26.55. The patients' self-perception of their sexuality was assessed, and the frequency of sexual intercourse was noted. RESULTS: The prevalence of female sexual dysfunction in women with RA was 49.3% versus 23.9% in controls, with a significant difference (p = 0.002). Comparison between both groups as regards the mean of area scores of FSFI revealed that desire, arousal, and satisfaction in patients with RA were significantly lower than those in the control group (p = 0.05, p = 0.038, and p = 0.024, respectively). The score of lubrification, orgasm, and pain was comparable between the two groups. In univariate analysis, a significant association was found between sexual dysfunction and pain (p = 0.001), tender joint counts (p = 0.04), DAS28 ESR (p = 0.043), fatigue (p = 0.028), and functional disability (p = 0.02). No association was found between sexual dysfunction and treatment. In multivariate analysis, only pain was a predictive factor of sexual dysfunction in patients (p = 0.05, OR = 1.26 [1.16-1.3]). Based on patients' self-perception of their sexual function, 26.1% of patients reported a negative impact of RA on their sex life. According to them, the main factors influencing sexuality were joint pain (60.6%) and fatigue (51%). Moreover, 59% of patients reported a decrease in the frequency of sexual intercourse after the diagnosis of RA. However, no statistically significant difference was found between patients and controls in the frequency of sexual intercourse (p = 1). CONCLUSION: Our study suggests that patients with RA experience high level of impairment of sexual function in comparison with a control group. Health providers must consider sexual function as an important part of quality of life. A therapeutic education directed towards a patient could be proposed to approach sexuality.Key Points• The prevalence of female sexual dysfunction is higher in women with rheumatoid arthritis than in controls.• In multivariate analysis, the global pain intensity visual analog scale was the only predictive factor of sexual dysfunction in patients.• Based on patients' self-perception, joint pain and fatigue are the main factors influencing sexuality. | |
31830144 | Real world, big data cost of pharmaceutical treatment for rheumatoid arthritis in Greece. | 2019 | INTRODUCTION: Rheumatoid Arthritis (RA) is a highly prevalent autoimmune disease associated with joint inflammation and destruction. Treatment for RA, especially with biologic agents (biologics), improves patient functionality and quality of life and averts costly complications or disease progression. Cost of RA pharmaceutical treatment has rarely been reported on the basis of real-world, big data. This study reports on the real-world, big data RA pharmaceutical treatment cost in Greece. METHODS: The Business Intelligence database of the National Organization for Healthcare Services Provision (EOPYY) was used to identify and provide analytics on patients on treatment for RA. EOPYY is responsible for funding healthcare and pharmaceutical care services for approximately 95% of the population in the country. ICD-10 codes were applied to identify patients with RA and at least one reimbursed prescription between 1 June 2014 and 31 May 2015. RESULTS: 35,873 unique patients were recorded as undergoing treatment for RA. Total reimbursed treatment cost for the study period was €81,206,363.70, of which €52,732,142.18 (64.94%) was for treatment with biologics. Of that cost, €39,724,489.71 (48.32%) accounted for treatment with anti-TNFs and/or methotrexate/corticosteroids. CONCLUSION: Real world, big data analysis confirms that the major driver of RA pharmaceutical cost is, as expected, the cost of treatment with biologics. It is critical to be able to match this cost to the treatment outcome it produces to ensure an optimal, no-waste, evidence-based allocation of healthcare resources to need. | |
31245906 | Prevalence of methotrexate intolerance among patients with rheumatoid arthritis using the | 2019 Aug | AIM: Methotrexate (MTX) is the anchor drug for the treatment of rheumatoid arthritis (RA). MTX is associated with adverse events that limit its use. The MTX intolerance severity score (MISS) was developed to identify symptoms related to MTX use in juvenile idiopathic arthritis and RA patients. The aim of this study is to translate and validate the MISS in the Arabic language. METHODS: Forward and backward translation of the MISS were performed by two fluent Arabic translators and reviewed by three rheumatologists. Consecutive patients with RA who used MTX for ≥3 months were recruited from two tertiary care centers in Riyadh, Saudi Arabia. A test was considered positive if the patient scored ≥6 points. The internal consistency and stability of the items were evaluated using Cronbach's alpha and the test-retest method. RESULTS: A total of 185 patients were recruited. Of those patients, 158 (85.4%) were female. The mean (±SD) age and disease duration were 49.7 (±12.67) and 8.67 (±7.1) years, respectively. The mean Disease Activity Score of 28 joints was 3.2 (±1.3). Fifty-five (30%) patients were illiterate. Seventy-three (39.5%) patients had a positive MISS. Of those patients, 55 (75.3%) and 18 (24.7%) were using the oral and subcutaneous forms of MTX, respectively. The Arabic MISS had good internal consistency (Cronbach's alpha = 0.792) and a factorable study size for test-retest and factor analysis (Kaiser-Meyer-Olkin = 0.745). CONCLUSION: The Arabic MISS showed validity and good reliability in detecting MTX intolerance in RA patients. MTX intolerance is prevalent among RA patients. Larger studies are needed to confirm these findings. |
