25906279 | Prevalence and occupational impact of arthritis in Saskatchewan farmers. | 2015 | Agricultural workers have physically demanding occupations. In this study of Saskatchewan farmers, the authors examined (1) self-reported prevalence of physician-diagnosed rheumatoid arthritis and osteoarthritis; and (2) the impact of these chronic arthridities on engagement in physical tasks related to farming. This study was conducted through a cross-sectional analysis of baseline data from the Saskatchewan Farm Injury Cohort Study in which 2,473 adult residents upon 1,216 farms participated. Collected survey data included demographic and health information; regional musculoskeletal symptoms for each participant assessed via the Standard Nordic Questionnaire; and engagement in various specific physical tasks or activities associated with mixed farming practices. Of the 2,473 respondents, 13% reported chronic arthritic diagnoses (10% osteoarthritis, 4% rheumatoid arthritis, with 1% from each category overlapping with both forms of arthritis). Participants reporting arthritis were more likely to also report disabling musculoskeletal symptoms involving their shoulders, elbows, hands, lower back, hips, knees, and ankles. Farmers with arthritis reported less participation in all physical farming activities studied, including various machinery operations, herd maintenance and veterinary activities, overhead work, shoveling/pitchfork work, and lifting/carrying. When adjusted for age, gender, and comorbidities, operation of combines and shoveling/pitchfork work continued to be significantly less engaged in by farmers with arthritis. The overall prevalence of arthritis was consistent with general population prevalence, although the category of rheumatoid arthritis was overrepresented. Farmers with arthritis were significantly less likely to participate in combine operation and shoveling/pitchfork chores compared with their counterparts without arthritis. | |
27843373 | The onset of rheumatoid arthritis following trauma. | 2016 | BACKGROUND: Rheumatoid arthritis (RA) is known to have many predisposing factors. OBJECTIVE: We studied individuals whose RA was initiated by physical injuries. PATIENTS AND METHODS: Sixty patients (43 females), previously well, developed RA following trauma. No other known environmental or familial influences were present. Fourteen sustained a fracture; of the 46 who did not, 36 sustained multiple injuries that in part involved the axial skeleton. Subsequent unremitting daily pain, stiffness, limited motion, pain on motion, and/or swelling in the injured areas were mandatory for inclusion. RESULTS: Nine months after injuries (span: 2 weeks-36 months), more obvious signs of inflammation (IM) appeared in multiple other joints that were previously not affected by the original trauma. In those with laboratory tests done prior to the spread of IM (30/60), 22 (73%) were normal until an average 8 months after the spread of IM. Of the entire cohort of 60, only 23% had a positive rheumatoid factor, but 43% had a positive antinuclear antibody. CONCLUSION: It seems apparent that any severe trauma to a joint may precipitate an ongoing localized chronic inflammatory disorder for an indefinite period of time, which may then lead to the spread of IM to multiple other joints. The initiation of RA following trauma warrants consideration as a legitimate entity. | |
25861409 | Surgical management of the forefoot in patients with rheumatoid arthritis - a review artic | 2015 | Foot and ankle pathologies cause a significant disease burden on rheumatoid patients. Forefoot pathologies causes pain, callosities and possibly ulceration, and can cause problems with footwear. Forefoot correction in rheumatoid patients has historically comprised of excision of diseased joints. While satisfaction was high with this procedure, complications, changing expectations and improvement in medical therapy have raised expectation of patients, physicians and surgeons alike. This review assesses the role of joint preserving osteotomies and arthrodesis, as well as associated complications. It also describes the role of the multidisciplinary team in the management of these patients. | |
29539475 | Severe erosive polyarthritis in a human skeleton dated to the early modern period of Japan | 2015 Mar | A human skeleton apparently afflicted with severe polyarthritis was unearthed from an early modern grave at the Tamukai site in the northernmost part of Honshu in Japan. The bones, likely from a late middle-aged male, showed severe resorptive lesions and ankylosis in many of the peripheral joints. Lesions were found in both bilateral and symmetrical distributions, sometimes accompanied by juxta-articular osteoporosis. Differential diagnoses included either rheumatoid arthritis, psoriatic arthritis, or leprosy, with psoriatic arthritis being the most likely. Whatever the final diagnosis, the identification of arthritis mutilans is clear. Because some bones were missing and a mixture of characteristics of both types of arthritis was evident, it was impossible to make a definitive diagnosis. However, this case is valuable for the severity of the lesions and the rarity of erosive polyarthritis found in archaeological skeletons from an Asian site. | |
27790499 | A Case of Macrophage Activation Syndrome with Acute Respiratory Distress Syndrome. | 2016 Sep | Macrophage Activation Syndrome (MAS) is a rare form of Haemophagocytic Lymphohistiocytosis (HLH) associated with rheumatologic conditions. It is characterised by haemophagocytosis and cytokine overproduction, resulting from the activation and uncontrolled proliferation of T lymphocytes and macrophages. The patient being reported is an elderly female with Rheumatoid Arthritis (RA), who presented with fever and was found to have MAS. She later developed Acute Respiratory Distress Syndrome (ARDS) and died. Such a scenario has rarely been reported. | |
26636433 | Brief Report: Patients With Primary Sjögren's Syndrome Who Are Positive for Autoantibodie | 2016 Mar | OBJECTIVE: Autoantibodies reactive with Ro52 (tripartite motif-containing protein 21 [TRIM21]) are detected in 70% of patients with primary Sjögren's syndrome (SS). TRIM21 belongs to a 34-member C-IV family of TRIM proteins. Although autoantibodies against other TRIM proteins within the C-IV family have been detected in the sera of patients with primary SS, their clinical relevance remains unclear. This study was undertaken to investigate the frequency of anti-TRIM38 in patients with primary SS and evaluate its association with various clinical measures of the disease. METHODS: Serum samples from patients with primary SS (n = 235) and controls (n = 50) were analyzed for reactivity with in vitro-transcribed and -translated (35) S-methionine-labeled TRIM38 protein. The associations of anti-TRIM38 with various laboratory and clinical measures of primary SS were evaluated. Reactivity of anti-TRIM38 with different structural domains of TRIM38 was analyzed. Affinity-purified anti-TRIM38 antibodies were used to immunoprecipitate TRIM21. RESULTS: TRIM38-reactive autoantibodies were detected in the sera of 24 of the 235 patients with primary SS and 2 of the 50 controls. Anti-TRIM38 positivity was significantly associated with the presence of anti-Ro60, anti-Ro52, anti-La, rheumatoid factor, and hypergammaglobulinemia. Clinically, anti-TRIM38 was associated with significantly higher ocular surface staining scores, lower Schirmer's test scores, and minor labial salivary gland biopsy focus scores of ≥3.0. Anti-TRIM38 antibodies mainly recognized the cortactin-binding protein 2 (CortBP-2; amino acids 128-238) and the B30.2/SPRY (amino acids 268-465) domains on TRIM38. Affinity-purified antibodies to TRIM38-CortBP-2 and TRIM38-B30.2/SPRY domains reacted with TRIM21. CONCLUSION: Our data demonstrate that anti-TRIM38 specificity arising in a subset of patients with primary SS is associated with increased severity of the disease. | |
26509058 | Genetics of RA susceptibility, what comes next? | 2015 | Genome-wide association studies (GWASs) have been used to great effect to identify genetic susceptibility loci for complex disease. A series of GWAS and meta-analyses have informed the discovery of over 100 loci for rheumatoid arthritis (RA). In common with findings in other autoimmune diseases the lead signals for the majority of these loci do not map to known gene sequences. In order to realise the benefit of investment in GWAS studies it is vital we determine how disease associated alleles function to influence disease processes. This is leading to rapid development in our knowledge as to the function of non-coding regions of the genome. Here we consider possible functional mechanisms for intergenic RA-associated variants which lie within lncRNA sequences. | |
26170903 | Anti-inflammatory functions of Houttuynia cordata Thunb. and its compounds: A perspective | 2015 Jul | The aim of this review was to take a look at the anti-inflammatory functions of Houttuynia cordata Thunb. (HCT) that have been illustrated in the literature and to explore new fields in which HCT could be used in the future. The use of HCT has been described in broad inflammatory domains, where it has exhibited a variety of activities, including antiviral, antibacterial, antiparasitic and immunostimulant activity, with high efficiency, mild features and definite therapeutic effects. The numerous anti-inflammatory functions of HCT have demonstrated that HCT has wide application prospects. New uses of HCT and the full extent of its utilization await further investigation. The basic pathological change of rheumatoid arthritis (RA) is synovial proliferation which leads to joint destruction in the long-term. There are types of drugs that have been used clinically for patients with RA, however, due to their side-effects or high prices their broad usage is limited. A safe and low-cost drug is urgently required to be developed for the clinical usage of patients with RA. Thus, HCT has the potential to be a good candidate in the treatment of rheumatoid arthritis. | |
27407274 | Osteoporosis diagnostics in patients with rheumatoid arthritis. | 2016 | Rheumatoid arthritis (RA) is a chronic systemic connective tissue disease. The development of comorbidities often occurs in the course of RA. One of them is osteoporosis, which has serious social and economic effects and may contribute to the increase in the degree of disability and premature death of the patient. Due to the young age in which RA disease occurs, densitometry (DXA) of the lumbar spine is the basic examination in osteoporosis diagnostics. In the course of RA, much more frequently than in healthy persons of the same age, osteoporotic fractures of vertebral bodies occur, which hinder a correct assessment in the DXA test. Rheumatoid arthritis patients often undergo computed tomography (CT) examination of the abdominal cavity for other medical indications than suspected spinal injury. Then, CT examination may also serve for the assessment of bone density, especially in patients with osteoporotic fractures. | |

Patients with JRA that got position of the child-invalid are given individual program of the rehabilitation that includes medical, professional, sport and physical, social adaptation that gives ability control recommendations for both--physicians and parents. | |
28115778 | The beneficial effects of rehabilitation on hand function in patients with rheumatoid arth | 2016 | OBJECTIVES: The hand is one of the main elements of the rehabilitation of patients with rheumatoid arthritis (RA) due to deformities, which occur in approximately 90% of patients. It is a serious problem, both in the psychological and functional aspect, connected with muscle strength reduction, a limited range of motion and non-acceptance of the changes in the shape of the limb. The study aimed to assess the effect of rehabilitation on the function of the hand in rheumatoid arthritis. MATERIAL AND METHODS: The study group consisted of 40 women with RA. The patients had been previously treated at the Rehabilitation Department of the National Institute of Geriatrics, Rheumatology and Rehabilitation in Warsaw. The study group underwent 3 weeks of rehabilitation involving individual therapy, exercises with equipment, patient education and physical therapy. The control group included women without a diagnosis of RA, hands pain-free and fully mobile. In both groups the hand was assessed for grip value, grip quality and manipulative ability. In the study group the basis of pain intensity was noted. The measurements were performed twice - prior to the rehabilitation and after 3 weeks of rehabilitation in women with RA and once in women without hand problems. RESULTS: The results obtained revealed marked limitation of hand function in patients with rheumatoid arthritis. The treatment resulted in an improvement of all assessed parameters except cylindrical grip, in which only a part of the findings was statistically significant. CONCLUSIONS: The analysis of the study material showed that appropriately adjusted and conducted hand physiotherapy in women with rheumatoid arthritis contributed to the improvement of its function by pain reduction, improved value and quality of grip, and also increased manipulative ability. | |
27472698 | Parenchymal lung involvement in adult-onset Still disease: A STROBE-compliant case series | 2016 Jul | Parenchymal lung involvement (PLI) in adult-onset Still's disease (AOSD) has seldom, if ever, been studied. We examine here retrospective cohort AOSD cases and present a review of the literature (1971-2014) on AOSD-related PLI cases.Patients with PLI were identified in 57 AOSD cases. For inclusion, the patients had to fulfill Yamaguchi or Fautrel classification criteria, show respiratory symptoms, and have imaging evidence of pulmonary involvement, and data allowing exclusion of infectious, cardiogenic, toxic, or iatrogenic cause of PLI should be available. This AOSD + PLI group was compared with a control group (non-PLI-complicated AOSD cases from the same cohort).AOSD + PLI was found in 3 out of the 57 patients with AOSD (5.3%) and the literature mentioned 27 patients. Among these 30 AOSD + PLI cases, 12 presented an acute respiratory distress syndrome (ARDS) and the remaining 18 another PLI. In the latter, a nonspecific interstitial pneumonia computed tomography pattern prevailed in the lower lobes, pulmonary function tests showed a restrictive lung function, the alveolar differential cell count was neutrophilic in half of the cases, and the histological findings were consistent with bronchiolitis and nonspecific interstitial pneumonia. Corticosteroids were fully efficient in all but 3 patients. Ten out of 12 ARDS cases occurred during the first year of the disease course. All ARDS-complicated AOSD cases received corticosteroids with favorable outcomes in 10 (2 deceased). Most PLIs occurred during the systemic onset of AOSD.PLI may occur in 5% of AOSDs, of which ARDS is the most severe. Very often, corticosteroids are efficient in controlling this complication. | |
27964794 | The role of the gastrointestinal tract in the pathogenesis of rheumatic diseases. | 2016 Oct | Dysregulation of the intestinal epithelial barrier in genetically susceptible individuals may lead to both intestinal and extraintestinal autoimmune disorders. There is emerging literature on the role of microbiota changes in the pathogenesis of systemic rheumatic diseases such as rheumatoid arthritis, spondyloarthropathies, and connective tissue diseases. Although the role of the gastrointestinal tract in the pathogenesis of spondyloartropathies is well defined and many studies underline the importance of gastrointestinal inflammation in modulating local and systemic inflammation, the data are inconclusive regarding the effect of dysbiosis on rheumatoid arthritis and connective tissue diseases. This review aims to summarize current data on the role of the gastrointestinal involvement and intestinal microbiota in the pathogenesis of systemic rheumatic disease. | |
27445820 | Hypoxia-Inducible Factor (HIF) as a Target for Novel Therapies in Rheumatoid Arthritis. | 2016 | Hypoxia is an important micro-environmental characteristic of rheumatoid arthritis (RA). Hypoxia-inducible factors (HIF) are key transcriptional factors that are highly expressed in RA synovium to regulate the adaptive responses to this hypoxic milieu. Accumulating evidence supports hypoxia and HIFs in regulating a number of important pathophysiological characteristics of RA, including synovial inflammation, angiogenesis, and cartilage destruction. Experimental and clinical data have confirmed the upregulation of both HIF-1α and HIF-2α in RA. This review will focus on the differential expression of HIFs within the synovial joint and its functional behavior in different cell types to regulate RA progression. Potential development of new therapeutic strategies targeting HIF-regulated pathways at sites of disease in RA will also be addressed. | |
27843367 | Management of rheumatoid arthritis during pregnancy: challenges and solutions. | 2016 | Rheumatoid arthritis, a chronic inflammatory autoimmune disease with significant physical disability, affects women three times more frequently than men, often in their childbearing years. Parenthood decisions can be challenging, often affected by perceptions of their disease state, health care needs, and complex pharmacological treatments. Many women struggle to find adequate information to guide them on pregnancy planning, lactation, and early parenting in relation to their chronic condition. The expanded availability and choice of pharmacotherapies have supported optimal disease control prior to conception and enhanced physical capabilities for women to successfully overcome the challenges of raising children but require a detailed understanding of their risks and safety in the setting of pregnancy and breastfeeding. This review outlines the various situational challenges faced by rheumatologists in providing care to men and women in the reproductive age group interested in starting a family. Up to date evidence-based solutions particularly focusing on the safe use of disease-modifying antirheumatic drugs and biologic response modifiers to assist rheumatologists in the care of pregnant and lactating women with RA are reviewed. | |
25849672 | Bucillamine-induced membranous nephropathy with crescent formation in a patient with rheum | 2015 Jan | Bucillamine is a disease-modifying antirheumatic drug that is structurally similar to D-penicillamine. The major renal side effect of bucillamine and D-penicillamine is proteinuria caused by membranous nephropathy (MN). In addition to MN, combined crescent formation has been occasionally reported in D-penicillamine-induced MN, while crescent formation has been rarely reported in bucillamine-treated cases. Here, we describe a 76-year-old female who presented with nephrotic syndrome and rapidly progressive glomerulonephritis. She was receiving bucillamine as initial treatment for recently diagnosed rheumatoid arthritis, and renal biopsy showed MN with crescent formation. To the best of our knowledge, this is the first report of bucillamine-induced MN with crescent formation in the English literature. | |
25621215 | Hand bone mass in rheumatoid arthritis: A review of the literature. | 2015 Jan 18 | Rheumatoid arthritis (RA) is a common chronic inflammatory disease and periarticular osteoporosis or osteopenia of the inflamed hand joints is an early feature of RA. Quantitative measurement of hand bone loss may be an outcome measure for the detection of joint destruction and disease progression in early RA. This systematic review examines the published literature reporting hand bone mass in patients with RA, particularly those using the dual X-ray absorptiometry (DXA) methods. The majority of the studies reported that hand bone loss is associated with disease activity, functional status and radiological progression in early RA. Quantitative measurement of hand bone mineral density by DXA may be a useful and practical outcome measure in RA and may be predictive for radiographic progression or functional status in patients with early RA. | |
28090179 | Correlation of Demographic and Clinical Characteristics with Rheumatoid Factor Seropositiv | 2016 Nov | BACKGROUND: The rheumatoid factor (RF) blood test is the most commonly adopted test for the diagnosis of rheumatoid arthritis (RA). RA patients who are seropositive for RF might face a greater likelihood of developing more aggressive symptoms. METHODS: Our goal was to study the demographic and clinical characteristics, as well as their correlation with RF seropositivity, among a series of 80 RA patients aged ≥ 18 years who attend Hospital Universiti Sains Malaysia (HUSM). RESULTS: Of the 80 RA patients included in this study, 66 (82.5%) were female and 14 (17.5%) were male. No significant associations between RF seropositivity and demographic and/or clinical characteristics or other laboratory investigations were observed, including gender, morning stiffness, individual joint involvement (from multiple sites of the body), and erythrocyte sedimentation rate (ESR) measurement. However, a significant association between RF seropositivity and patients aged ≥ 50 was found (P = 0.032). CONCLUSION: RF seropositivity was found to be more common in much older RA patients. | |
27504023 | Cardiovascular risk assessment in rheumatoid arthritis - controversies and the new approac | 2016 | The current methods of cardiovascular (CV) risk assessment in the course of inflammatory connective tissue diseases are a subject of considerable controversy. Comparing different methods of CV risk assessment in current rheumatoid arthritis (RA) guidelines, only a few of them recommend the use of formal risk calculators. These are the EULAR guidelines suggesting the use of SCORE and the British Society for Rheumatology guidelines performed in collaboration with NICE preferring the use of QRISK-2. Analyzing the latest American and British reports, two main concepts could be identified. The first one is to focus on risk calculators developed for the general population taking into account RA, and the calculator that might fulfill this role is the new QRISK-2 presented by NICE in 2014. The second concept is to create RA-specific risk calculators, such as the Expanded Cardiovascular Risk Prediction Score for RA. In this review we also discuss the efficiency of a new Pooled Cohort Equation and other calculators in the general and RA population. | |
25972704 | Shortening femoral osteotomy with stemmed resurfacing total knee arthroplasty for severe f | 2015 Jun | Juvenile Rheumatoid Arthritis (JRA) is a progressive disease characterized by pain, swelling, and loss of motion in the joints of adolescents. Total knee arthroplasty (TKA) can be indicated, during the adolescent years, in patients with advanced JRA to alleviate pain and improve function. Because of the relative infrequency of TKA in patients with JRA, evaluation of the type of TKA performed and the results merit review. This case report present two distinct operations performed to obtain full extension. 1. Distal femoral resection with conversion to hinged arthroplasty. 2. Femoral shortening osteotomy with resurfacing TKA. |
