26252664 Can social support work virtually? Evaluation of rheumatoid arthritis patients' experience 2015 Jul BACKGROUND: There is strong empirical evidence that the support that chronic patients receive from their environment is fundamental for the way they cope with physical and psychological suffering. Nevertheless, in the case of rheumatoid arthritis (RA), providing the appropriate social support is still a challenge, and such support has often proven to be elusive and unreliable in helping patients to manage the disease. OBJECTIVES: To explore whether and how social support for RA patients can be provided online, and to assess the conditions under which such support is effective. An online support tool was designed to provide patients with both tailored information and opportunities to interact online with health professionals and fellow sufferers. The general purpose was to identify where the support provided did - or did not - help patients, and to judge whether the determinants of success lay more within patients - their engagement and willingness to participate - or within the design of the website itself. METHODS: The present study reports qualitative interviews with 19 users of the tool. A more specific purpose was to elaborate qualitatively on results from a quantitative survey of users, which indicated that any positive impact was confined to practical matters of pain management rather than extending to more fundamental psychological outcomes such as acceptance. RESULTS AND CONCLUSIONS: Overall, online learning and interaction can do much to help patients with the everyday stresses of their disease; however, its potential for more durable positive impact depends on various individual characteristics such as personality traits, existing social networks, and the severity and longevity of the disease.
26853518 Systemic effects of surgical intervention on disease activity, daily function, and medicat 2016 Oct OBJECTIVES: Although tight control of rheumatoid arthritis (RA) has been achieved through the development of effective medication, surgical intervention is still required for a certain subpopulation of patients. To examine the systemic effects of orthopaedic surgery, we evaluated improvements in disease activity, daily function, and medication after surgery. METHOD: A prospective cohort study was conducted in 196 cases of elective orthopaedic surgery in 150 patients with RA from January 2011 to March 2014 in our institution. The 28-joint count Disease Activity Score based on erythrocyte sedimentation rate (DAS28-ESR) and modified Health Assessment Questionnaire (mHAQ) scores just before surgery and at 6 and 12 months after surgery were examined prospectively. Concomitant medications were also investigated. RESULTS: Significant improvement was seen in the DAS28-ESR and mHAQ scores for replacement surgery in both the upper and lower extremities, and for arthroplasty/arthrodesis in the upper extremities at the 12-month follow-up. Partial mHAQ scores for the lower extremities were significantly reduced in lower replacement surgery, and partial mHAQ scores for the upper extremities were significantly reduced in upper arthroplasty/arthrodesis surgery. Although the use of conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) did not decrease after surgery, the dose of prednisolone (PSL) decreased significantly at 12 months after surgery, especially in the well-controlled group and in surgical procedures in the lower extremities. CONCLUSIONS: Elective orthopaedic surgery improves both systemic disease activity and general functional impairment. Orthopaedic surgery is effective in reducing the amount of medication required postoperatively.
25710855 Association of regional and cultural factors with the prevalence of rheumatoid arthritis i 2015 Mar BACKGROUND: The overall estimated prevalence of rheumatoid arthritis (RA) in Mexico is 1.6%, but there are major variations in different geographic areas of the country. OBJECTIVE: This study aimed to determine the impact of individual and regional variables on the geographic distribution of RA in Mexico. METHODS: This multilevel analysis used data from a cross-sectional study that investigated the prevalence of RA among 19,213 individuals older than 18 years throughout 5 geographic regions in Mexico. Logistic regression models were used to determine predictors of RA, including individual and regional variables as well as cultural factors. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were determined. RESULTS: The prevalence of RA varied from 0.77% to 2.8% across the 5 regions. Individual factors associated with RA were sex (OR, 2.32; 95% CI, 1.74-3.07), previous medical diagnosis of RA ( OR 3.3, 95%CI: 2919–5.1 [corrected]), disability (OR, 2.07; 95% CI, 1.48-2.93), and the 56- to 65-year age group (OR, 1.95; 95% CI, 1.08-3.74). The regional factor of speaking an indigenous language had an OR of 2.27 (95% CI, 1.13-4.55). CONCLUSIONS: Various individual and regional factors were associated with variations in the prevalence of RA in the Mexican population.
26608972 Multibiomarker disease activity score and C-reactive protein in a cross-sectional observat 2016 Apr OBJECTIVES: To examine the association between a multibiomarker disease activity (MBDA) score, CRP and clinical disease activity measures among RA patients with and without concomitant FM. METHODS: In an observational cohort of patients with established RA, we performed a cross-sectional analysis comparing MBDA scores with CRP by rank correlation and cross-classification. MBDA scores, CRP and clinical measures of disease activity were compared between patients with RA alone and RA with concomitant FM (RA and FM) by univariate and multivariate analyses. RESULTS: CRP was ⩽1.0 mg/dl for 184 of 198 patients (93%). MBDA scores correlated with CRP (r = 0.755, P < 0.001), but were often discordant, being moderate or high for 19%, 55% and 87% of patients with CRP ⩽0.1, 0.1 to ⩽0.3, or 0.3 to ⩽1.0 mg/dl, respectively. Among patients with CRP ⩽1.0 mg/dl, swollen joint count (SJC) increased linearly across levels of MBDA score, both with (P = 0.021) and without (P = 0.004) adjustment for CRP, whereas CRP was not associated with SJC. The 28-joint-DAS-CRP, other composite measures, and their non-joint-count component measures were significantly greater for patients with RA and FM (n = 25) versus RA alone (n = 173) (all P ⩽ 0.005). MBDA scores and CRP were similar between groups. CONCLUSION: MBDA scores frequently indicated RA disease activity when CRP did not. Neither one was significantly greater among patients with RA and FM versus RA alone. Thus, MBDA score may be a useful objective measure for identifying RA patients with active inflammation when CRP is low (⩽1.0 mg/dl), including RA patients with concomitant FM.
26385370 Relationship of multi-biomarker disease activity score and other risk factors with radiogr 2016 Feb OBJECTIVES: To evaluate the multi-biomarker disease activity (MBDA) score as a predictor of radiographic progression and compare it with other risk factors among patients with established RA receiving non-biologic DMARDs. METHODS: For 163 patients with RA, we assessed 271 visits for MBDA score (scale of 1-100), clinical data and subsequent 1-year radiographic progression (change in Sharp-van der Heijde score [SHS]). Scatter plot and non-parametric quantile regression curves evaluated the relationship between the MBDA score and change in SHS. Changes in joint space narrowing and erosions were compared among MBDA categories with Wilcoxon rank-sum tests. The ability of the MBDA score to independently predict progression was determined by multivariate models and cross-classification of MBDA score with other risk factors. Generalized estimating equation methodology was used in model estimations to adjust for same-patient visits, always ≥1 year apart. RESULTS: Patient characteristics included 67% female, 66%/67% RF(+)/anti-CCP(+); mean age 55 years, MBDA score 43 (moderate = 30-44); median disease duration 4.6 years, SHS 23. Radiographic progression was infrequent for low MBDA scores. Relative risk for progression increased continuously as the MBDA score increased, reaching 17.4 for change in SHS >5 with MBDA scores ≥60. Joint space narrowing and erosion progression were associated with MBDA score. MBDA score was associated with radiographic progression after adjustments for other risk factors. MBDA score significantly differentiated risk for progression when swollen joint count, CRP or DAS28-CRP was low, and among seropositive patients. CONCLUSION: MBDA score enhanced the ability of conventional risk factors to predict radiographic progression in patients with established RA receiving non-biologic DMARDs.
26200604 Comparison of the disease activity score using the erythrocyte sedimentation rate and C-re 2016 Dec OBJECTIVE: The Disease Activity Score based on 28 joints (DAS28) has been widely used in clinical practice and research studies of rheumatoid arthritis (RA). The objective of this study was to evaluate the discordance in the DAS28 based on the erythrocyte sedimentation rate (ESR) versus C-reactive protein (CRP) levels in Korean patients with RA. METHODS: From August to December 2011, 540 patients with RA who visited two rheumatology clinics affiliated with Hallym University (Korea) and had at least one DAS28 evaluation were examined. RESULTS: The mean age of the included patients was 53 years, and 82% were female. The mean duration of disease was 32.9 ± 41.2 months. The mean DAS28-ESR was higher than the DAS28-CRP (3.65 vs. 3.44; P < 0.001). In the DAS28-ESR group, 126 patients (23.3%) satisfied the criteria for remission versus 134 (24.8%) in the DAS28-CRP group. High disease activity was determined in 80 (14.8%) patients in the DAS28-ESR group and in 43 (8.0%) in the DAS28-CRP group. A comparison of the two groups with respect to four DAS28 disease activity categories showed agreement in 344 patients (63.7%; κ = 0.45). In classifying patients as European League Against Rheumatism (EULAR) responders, agreement between the two methods was shown in 56 patients (71.8%; κ = 0.76). When disagreements between the two scores occurred, more patients had a better EULAR response based on the DAS28-ESR than on the DAS28-CRP (19.2% vs. 8.9%, respectively). CONCLUSION: The discordance between the ESR-based and CRP-based DAS28 could affect clinical treatment decisions for patients with RA.
27040050 Changes in foot function, disease activity, and disability after forefoot resection arthro 2016 The purpose of this study was to investigate the changes in foot function, disease activity, and disability in patients with RA after resection arthroplasty of the forefoot (arthroplasty). Arthroplasty was performed on 11 patients with RA. All study patients underwent clinical assessment to measure disease activity (Disease Activity Score in 28 Joints-C-reactive protein, DAS28-CRP), disability (Health Assessment Questionnaire-Disability Index, HAQ-DI) and foot function (Foot Function Index, FFI) at the following stages: preoperatively and 1, 3, and 12 months after surgery. Following arthroplasty, foot function improved significantly, as assessed by FFI total and subscales (pain, disability, and limitation of activity) (P<0.001, P<0.001, P<0.001, and P=0.002, respectively). Disease activity was significantly improved in relation to DAS28-CRP and its subscales of number of swollen joints and patient global assessment (PtGA) (P=0.033, P=0.008, and P=0.038, respectively). There was no significant difference in disability, as assessed by the HAQ-DI and its subscale, HAQ-walking (P=0.150 and P=0.597, respectively). Foot function improved significantly after arthroplasty, and was maintained at 12 months postoperatively. Additionally, our study showed that disease activity and its subscale PtGA improved after arthroplasty.
25384985 Temporal effect of depressive symptoms on the longitudinal evolution of rheumatoid arthrit 2015 May OBJECTIVE: Depression is common in the rheumatoid arthritis (RA) population, yet little is known of its effect on the course of disease activity. The aim of our study was to determine if prevalent and incident depressive symptoms influenced longitudinal changes in RA disease activity. METHODS: RA patients with and without depressive symptoms were identified using single-item questions from an existing registry sample. Mixed-effects models were used to examine changes in disease activity over 2 years in those with and without prevalent and incident depressive symptoms. Outcome variables included composite disease activity, joint counts, global assessments, pain, function, and acute-phase reactants. Model-based outcome estimations at the index dates and corresponding 1- and 2-year changes were calculated. RESULTS: Rates of disease activity change were significantly different in patients with a lifetime prevalence of symptomology, but not incident depressive symptoms, when compared to controls. Prior symptoms were associated with slower rates of disease activity decline, evidenced by the estimated 1-year Clinical Disease Activity Index changes: -3.0 (-3.3, -2.6) and -4.0 (-4.3, -3.6) in patients with and without lifetime prevalence, respectively. Analogous results were obtained for most of the other disease activity outcomes; although, there was no temporal effect of prevalent symptoms of depression on swollen joints and acute-phase reactants. CONCLUSION: Depressive symptoms temporally influence the evolution of RA disease activity, and the magnitude is dependent on the time of symptomatic onset. However, the effect is limited to patient-reported pain, global assessment, and function, as well as physician-reported global assessment and tender joints.
25618175 Pain and difficulties performing valued life activities in women and men with rheumatoid a 2015 Aug This study aimed to examine the difficulties with performing valued life activities in relation to pain intensity in women and men with rheumatoid arthritis (RA). In total, 737 persons with RA (73 % women) from three rheumatology units in Sweden responded to a questionnaire measuring performance of 33 valued life activities and self-rated pain. The relationships between performance of valued life activities (VLAs) and pain (measured by visual analogue scale (VAS)) were analysed based on gender. Multiple linear regression analyses were conducted with the total VLA score as dependent variable. Women reported more pain and difficulties in performing valued life activities than men. Across genders, 85 % reported at least one valued life activity affected by RA. Significantly more women than men encountered difficulties in performing some activities such as cooking, gardening and meeting new people. Women reported higher pain intensity (35 mm) than men (31 mm). Almost all 33 difficulty ratings for valued life activities were higher among persons with high pain (>40 mm) than persons with lower pain. Difficulty ratings for valued life activities correlated positively with pain in persons with lower pain, but not among those with high pain. The results highlight the importance of addressing pain, especially among women with RA, as they reported pain to impact on their valued life activities. Interestingly, this was evident also in women with lower levels of pain.
26517752 Short-Term Efficacy Reliably Predicts Long-Term Clinical Benefit in Rheumatoid Arthritis C 2016 Jul The objective of this study was to assess the relationship between short-term and long-term treatment effects measured by the American College of Rheumatology (ACR) 50 responses and to assess the feasibility of predicting 6-month efficacy from short-term data. A rheumatoid arthritis (RA) database was constructed from 68 reported trials. We focused on the relationship between 3- and 6-month ACR50 treatment effects and developed a generalized nonlinear model to quantify the relationship and test the impact of covariates. The ΔACR50 at 6 months strongly correlated with that at 3 months, moderately correlated with that at 2 months, and only weakly correlated with results obtained at <2 months. A scaling factor that reflected the ratio of 6- to 3-month treatment effects was estimated to be 0.997, suggesting that the treatment effects at 3 months are approaching a "plateau." Drug classes, baseline Disease Activity Score in 28 Joints, and the magnitude of control arm response did not show significant impacts on the scaling factor. This work quantitatively supports the empirical clinical development paradigm of using 3-month efficacy data to predict long-term efficacy and to inform the probability of clinical success based on early efficacy readout.
27217240 Role of Serum cartilage oligomeric matrix protein (COMP) in the diagnosis of rheumatoid ar 2016 Aug OBJECTIVE: To analyse the role of serum cartilage oligomeric matrix protein (COMP) levels in the differential diagnosis of rheumatoid arthritis (RA). METHODS: This case-control study analysed the clinical and laboratory characteristics of patients with RA and healthy control subjects. The diagnostic ability of COMP for RA was evaluated by comparing it with anti-cyclic citrullinated peptide antibody levels. The sensitivity, specificity, positive and negative predictive values were calculated. RESULTS: The study enrolled 82 patients with RA and 34 healthy control subjects. The serum COMP level was significantly higher in patients with RA compared with control subjects (mean ± SD 29.51 ± 9.21 ng/ml versus 17.85 ± 5.55 ng/ml, respectively). The serum COMP level was significantly higher in patients with active RA compared with patients with RA in remission (mean ± SD 33.08 ± 8.80 ng/ml versus 24.94 ± 7.65 ng/ml, respectively). The cut-off value for COMP to discriminate patients with RA from healthy individuals was 21.51 ng/ml (sensitivity 0.817, specificity 0.882, positive predictive value 0.944, negative predictive value 0.667, and accuracy 0.836). CONCLUSION: The serum COMP level has the potential to be used as a biological marker for differentiating between patients with RA and healthy individuals.
26969209 Intermediate term evaluation of the Eclypse distal radio-ulnar prosthesis for rheumatoid a 2016 May HYPOTHESIS: Early medical management of rheumatoid arthritis with biotherapy has changed the traditional musculoskeletal damage from this disease. When the distal radio-ulnar joint (DRUJ) is involved, classic procedures may be inappropriate. We chose a hemi-arthroplasty of the DRUJ joint (Eclypse™) in patients with persistent synovitis and chondrolysis with a stable joint. The aim of this study was to assess the intermediate term results of this approach in these specific cases. MATERIALS AND METHODS: We report a retrospective study of 5 Eclypse arthropasties implanted between March 2005 and March 2011. There were 4 women and 1 man, mean age: 58.4years old (54-62) with RA that had been present for 21.6years (15-33). This hemi-arthroplasty replaced the ulnar head with a pyrocarbon component. Patients were evaluated by an independent observer for pain by VAS, range of motion, grip strength in the neutral position by Jamar dynamometer, pronation and supination strengths with a pronosupinator, DASH score and wrist X-rays. RESULTS: One patient was lost to follow-up and the 4 others underwent a follow-up evaluation at 64 months (43-90). There were no intra-operative or postoperative complications. The pain score at the final follow-up was 1.5/10 (0-4), pronation was 70° (60-80) and supination was 80° (80-80). Grip strength was 148% compared to the contralateral side (73-200%). Pronation and supination strengths were 1.7kg (1.5-2) and 2.1kg (2-2.5) respectively. The DASH score was 55.9 points (42.6 to 79.3). X-rays did not show any changes in the ulnar notch. CONCLUSION: This distal radio-ulnar arthroplasty is less invasive and preserves the bone and ligaments. Clinical results are rapid, remain stable over time and are well tolerated. This arthroplasty, which was initially developed for osteoarthritis and traumatic lesions of the DRUJ, is promising for specific cases of rheumatoid arthritis.
27551731 Disparities in care by insurance status for individuals with rheumatoid arthritis: analysi 2016 Dec OBJECTIVE: Treatment guidelines for rheumatoid arthritis (RA) recommend early, aggressive treatment with nonbiologic and biologic disease-modifying antirheumatic drugs (DMARDs) to minimize long-term disability. We aimed to assess differences in medical resource utilization, drug therapy, and health outcomes among RA patients by insurance type in the United States. METHODS: Individuals with a self-reported diagnosis of RA were identified in the Medical Expenditure Panel Survey (MEPS) database, 2006-2009. Data regarding sociodemographic characteristics, insurance type and status, and outcomes (including health care resource utilization, prescription medication use, health status, and patient-reported barriers to health care) were extracted. Multivariable regression analyses were used to examine the impact of insurance type (private, Medicare, Medicaid, or uninsured) on outcome measures while controlling for age group, sex, and race/ethnicity. RESULTS: A total of 693 individuals with a self-reported diagnosis of RA during the study period were identified; 423 were aged 18-64 years and 270 were aged ≥65 years. Among patients aged 18-64, those with Medicaid or who were uninsured were less likely than those with private insurance to visit a rheumatologist (adjusted odds ratio [aOR] 0.13 and 0.17, respectively; p < .001) and to receive biologic DMARDS (aOR 0.09 [p < .001] and 0.16 [p < .01], respectively); those with Medicaid were also less likely to receive nonbiologic DMARDS (aOR 0.26 [p < .01]). Those with Medicaid were more likely than those with private insurance to be unable/delayed in getting prescription drugs (aOR 2.9 [p < .05]), to experience cognitive, social, and physical limitations (aOR 8.7 [p < .001], 4.7 [p < .001], and 2.5 [p < .05], respectively); they also reported significantly lower general health and health-related quality of life. Patients aged ≥65 experienced greater equity in care and outcomes. CONCLUSIONS: Younger RA patients with Medicaid (including those who receive coverage under the Medicaid expansion component of the Affordable Care Act) may be at risk for inadequate treatment.
26832226 'The lesser of two evils…' - views of persons with rheumatoid arthritis on medication ad 2016 Jun OBJECTIVE: This study aimed to explore medication adherence among adherent and non-adherent persons suffering from rheumatoid arthritis (RA). A special focus was put on the reasons accounting for successful medication adherence and on potential barriers or facilitating factors. DESIGN: A qualitative study with semi-structured interviews was conducted. Eighteen participants were recruited through stratified purposive sampling according to their medication adherence level. Interviews were analysed by interpretative phenomenological analysis. RESULTS: Medication adherence behaviour was described on a continuum ranging from non-adherent to adherent. Participants' current adherence level was represented as a result of inner negotiations between a variety of influential factors and the successful application of a range of strategies. The influential factors were: experiences with medication, outcome expectations, knowledge of therapeutic options, the traits 'openness' and 'conscientiousness', belief in medical progress, characteristics of the medication, level of trust in one's physician, and perceived autonomy. Facilitating strategies were: establishing routines, using social support and the deliberate suppression of information about potential adverse events. CONCLUSION: The experience of and the reasons for medication (non-)adherence from the perspective of people with RA were explored comprehensively. Participants' ongoing negotiations between adherence and non-adherence emerged as a key finding with implications for health service providers.
25537932 Analysis of clinical factors related to the efficacy of shoulder arthroscopic synovectomy 2015 Apr Shoulder synovectomy is a well-known surgical treatment for rheumatoid arthritis. However, synovectomy alone is insufficient for improving range of motion clinically. We investigated the clinical factors related to the efficacy of shoulder synovectomy performed with capsular release in patients with rheumatoid arthritis. Fifty-four shoulders of 54 patients (12 males, 42 females; mean age 53.3 years) with rheumatoid arthritis were treated by synovectomy plus capsular release. The patients had a mean disease duration of 8.33 years, a mean follow-up period of 5.02 years, and 66.7% received biological treatment. The disease activity score 28 using C-reactive protein, range of motion of the shoulder, and Japanese Orthopaedic Association (JOA) score assessment were used to investigate clinical factors, analyzed by multiple regression analysis, associated with improved outcome. The average disease activity score 28 using C-reactive protein and JOA score improved significantly from 4.29 and 36.7 to 3.11 and 84.6, respectively, with the restoration of range of motion. Multiple regression analysis showed that disease duration and prednisolone were significantly associated with flexion degree and JOA score. Larsen grade and JOA score were not correlated significantly. There was no significant difference in the JOA score between the groups with or without biological medicinal treatment. Shoulder arthroscopic synovectomy performed with capsular release with or without biological treatment effectively improved function. Short disease duration and low prednisolone dose in rheumatoid arthritis were important for prediction of efficacy.
26153895 Bio-imaging and Photodynamic Therapy with Tetra Sulphonatophenyl Porphyrin (TSPP)-TiO2 Nan 2015 Jul 8 Since Rheumatoid arthritis (RA) is one of the major human joint diseases with unknown etiology, the early diagnosis and treatment of RA remains a challenge. In this contribution we have explored the possibility to utilize novel nanocomposites of tetera suplhonatophenyl porphyrin (TSPP) with titanium dioxide (TiO2) nanowhiskers (TP) as effective bio-imaging and photodynamic therapeutic (PDT) agent for RA theranostics. Our observations demonstrate that TP solution PDT have an ameliorating effect on the RA by decreasing significantly the IL-17 and TNF-α level in blood serum and fluorescent imaging could enable us to diagnose the disease in subclinical stages and bio-mark the RA insulted joint.
25993876 [Hepatic haemangioma as sistemic manifestation of rheumatoid arthritis]. 2015 This article presents the clinical data regarding to the incidence of hepatic haemangioma in rheumatoid arthritis (RA) patients. Haemangioma of the liver has been diagnosed by ultrasonography dramatically oftener in RA than in OA: in 8 from 37 RA pts and neither in 120 osteoarthritis pts. Hepatic haemangioma was associated with long standing erosive RA, extra-articular RA manifestations, high levels of rheumatoid factor and ACCP. Moreover in RA pts with hepatic haemangioma we revealed significantly raised levels of pro-inflammatory cytokines, which can impact on the angiogenesis in RA. Obtained clinical data may contribute in the understanding of liver vessels involvement in RA and pose the role of systemic connective tissue lesion and immune inflammation in this process.
27770827 Power Doppler ultrasonographic assessment of the joint-draining lymph node complex in rheu 2016 Oct 22 BACKGROUND: Emerging research on the mechanisms of disease chronicity in experimental arthritis has included a new focus on the draining lymph node (LN). Here, we combined clinical-serological analyses and power Doppler ultrasound (PDUS) imaging to delineate noninvasively the reciprocal relationship in vivo between the joint and the draining LN in patients with rheumatoid arthritis (RA). METHODS: Forty consecutive patients refractory to conventional synthetic disease-modifying anti-rheumatic drugs were examined through parallel PDUS of the hand-wrist joints and axillary LNs and compared with 20 healthy subjects. A semiquantitative score for LN gray-scale (GS) parameters (nodal hypertrophy and cortical structure) and LN PD signal was developed. A 6-month follow-up study with serial sonographic assessments was then performed on initiation of tumor necrosis factor (TNF) inhibitors. RESULTS: PDUS analysis of RA axillary LNs revealed the existence of marked inter-individual heterogeneity and of quantitative differences compared with healthy individuals in both GS and PD characteristics. RA LN changes were plastic, responsive to anti-TNF treatment, and displayed a degree of concordance with synovitis activity in peripheral joints. However, low LN PD signal at baseline despite active arthritis was strongly associated with a poor clinical response to TNF blockade. CONCLUSIONS: PDUS analysis of the draining LN in RA allows capture of measurable inter-individual differences and dynamic changes linked to the underlying pathologic process. LN and joint sonographic assessments are nonredundant approaches that may provide independent perspectives on peripheral disease and its evolution over time.
27906437 Vitamin D receptor polymorphisms as tool for early screening of severe bone loss in women 2016 Nov OBJECTIVE: Rheumatoid Arthritis (RA) is an autoimmune inflammatory disease that leads to local and systemic arthritis and bone loss. Exploring genetic markers of candidate genes in osteoporosis and inflammatory cytokine genes could be a useful tool for the early identification of bone loss and fracture risk in RA patients. The target of this study is the evaluation and correlation between of Single Nucleotide Polymorphisms (SNPs) of Vitamin D Receptor (VDR) and possible effects on bone loss in RA. PATIENTS AND METHODS: 40 Caucasian patients with RA (26 of them with a severe bone loss) and 40 healthy donors as control samples were genotyped for the VDR SNPs (called BsmI, ApaI, TaqI and FokI). The detection method is based on Restriction Fragment Length Polymorphism (RFLP). RESULTS: Genotyping profile shown no difference between RA patients and controls. Only VDR-TaqI genotype (TT vs. tt) seem to influence the bone density in females, but not in males. The mean differences of Bone Mass Density (BMD) at the lumbar spine in RA women with the tt allele were 4.7% compared to 0.1% in women with the TT allele (p < 0.05). CONCLUSIONS: The results of these studies support an association between specific VDR alleles and bone loss in RA. The TaqI t and BsmI B alleles were associated with an accelerated bone loss in RA, but not with a focal bone loss. These effects of VDR genotypes and vitamin D supplementation are not unexpected, given that the central pathological feature in RA is bone and joint destruction. The VDR SNPs genotyping should be a useful tool to screen early women RA patients with the bone loss.
26853597 Complex rehabilitation and the clinical condition of working rheumatoid arthritis patients 2016 AIM: Rehabilitation slows the progress of rheumatoid arthritis (RA) and prevents progression of disability. This study aimed to compare the impact of two rehabilitation programmes on pain, disease activity, locomotor function, global health and work ability forecast in RA patients. MATERIALS AND METHODS: Sixty-four employed women aged 24-65 years participated in the study. All patients underwent individual and instrumental kinesiotherapy. Thirty-two patients underwent cryogenic chamber therapy and local cryotherapy as well as non-weight-bearing, instrumental and individual kinesiotherapy. The remaining 32 patients received traditional rehabilitation in the form of electromagnetic and instrumental therapy, individual and pool-based non-weight-bearing kinesiotherapy. Rehabilitation lasted 3 weeks. Patients were examined three times: prior to rehabilitation, after 3 weeks of therapy and 3 months after completion of rehabilitation. The following study instruments were used: to assess disease activity: DAS-28; functional impairment: HAQ-DI; pain severity: VAS; patients' overall well-being: a scale from 0 to 100 (Global Health Index); and patients' own prognosis of fitness for work: the 6th question from Work Ability Index (WAI). Statistical analysis of data was performed using the STATISTICA 8.0 package. Mixed-design two-way analysis of variance was used for hypothesis testing. RESULTS: All patients improved after rehabilitation. The group of patients those who underwent cryotherapy had improved DAS-28, HAQ-DI, VAS and global health scores immediately following the 3-week rehabilitation programme (p < 0.001, p = 0.001, p = 0.007 and p < 0.001, respectively), as well as at the 3-month follow-up (p < 0.001, p < 0.001, p = 0.009 and p < 0.001, respectively). Rehabilitation using cryotherapy resulted in greater improvement in disease activity DAS-28 [F(2,105) = 5.700; p = 0.007; η(2) = 0.084] and HAQ-DI locomotor function scores [F(2,109) = 6.771; p = 0.003; η(2) = 0.098] compared to traditional rehabilitation. The impact of both forms of rehabilitation on patients' own prognosis of work ability in the next 2 years was not significant. Results of patients who underwent traditional approach showed decreased disease activity following the initial 3-week period; however, this improvement did not sustain to the end of follow-up, 3 months later. CONCLUSIONS: Complex rehabilitation in RA has a positive effect on patients' clinical condition. The rehabilitation programme that includes cryotherapy overtops traditional rehabilitation, particularly as regards improvement in locomotor function, disease activity and sustaining willingness to continue working and exerts long-lasting effect. IMPLICATIONS FOR REHABILITATION: Rehabilitation using cryotherapy is more effective in improving locomotor function, decreasing disease activity and sustaining willingness to continue working compared to traditional rehabilitation. Rehabilitation using cryotherapy significantly reduces the intensity of pain experienced by patients with RA, and this positive effect is maintained at 3 months post-rehabilitation. Complex rehabilitation, particularly treatment using cryotherapy, improves patients' subjective assessment of their overall well-being and perception of their disease. Complex rehabilitation in rheumatoid arthritis has a positive effect on patients' clinical condition.
