    This article reviews the literature concerning rheumatic manifestations of inflammatory bowel disease (IBD), including common immune-mediated pathways, frequency, clinical course and therapy. Musculoskeletal complications are frequent and well-recognized manifestations in IBD, and affect up to 33% of patients with IBD. The strong link between the bowel and the osteo-articular system is suggested by many clinical and experimental observations, notably in HLA-B27 transgenic rats. The autoimmune pathogenic mechanisms shared by IBD and spondyloarthropathies include genetic susceptibility to abnormal antigen presentation, aberrant recognition of self, the presence of autoantibodies against specific antigens shared by the colon and other extra-colonic tissues, and increased intestinal permeability. The response against microorganisms may have an important role through molecular mimicry and other mechanisms. Rheumatic manifestations of IBD have been divided into peripheral arthritis, and axial involvement, including sacroiliitis, with or without spondylitis, similar to idiopathic ankylosing spondylitis. Other periarticular features can occur, including enthesopathy, tendonitis, clubbing, periostitis, and granulomatous lesions of joints and bones. Osteoporosis and osteomalacia secondary to IBD and iatrogenic complications can also occur. The management of the rheumatic manifestations of IBD consists of physical therapy in combination with local injection of corticosteroids and nonsteroidal anti-inflammatory drugs; caution is in order however, because of their possible harmful effects on intestinal integrity, permeability, and even on gut inflammation. Sulfasalazine, methotrexate, azathioprine, cyclosporine and leflunomide should be used for selected indications. In some cases, tumor necrosis factor-alpha blocking agents should be considered as first-line therapy. PMID:19938189

    The foundation of the competence network for rheumatology, which is funded by the "Bundesministerium für Bildung und Forschung" (BMBF) since 1999, succeeded to create a unique research structure in Germany: medical doctors and scientists from six university rheumatology centres (Berlin, Düsseldorf, Erlangen, Freiburg, Hannover und Lübeck/Bad Bramstedt) work closely together with scientists doing basic research at the Deutsches Rheuma-Forschungszentrum (DRFZ), with rheumatological hospitals, reha-clinics, and rheumatologists. Jointly they are searching for causes of systemic inflammatory rheumatic diseases and try to improve therapies-nationwide and with an interdisciplinary approach. The primary objective of this collaboration is to transfer new scientific insights more rapidly in order to improve methods for diagnosis and patients treatment. PMID:14999386

    The population of Southern Africa is currently estimated at least 40 million and comprises people of 3 major--groups Negroid, Khoisan and Caucasoid. In addition to these, there are also smaller groups whose origin is Asiatic or Oriental, and a mixed group (coloured) which has resulted from the miscegenation between the Negroid-Caucasoid and other groups [1]. This great diversity of peoples and cultures permits unique opportunities for studies in comparative medicine which may provide valuable information about the pathogenesis and natural history of disease. The rheumatic diseases have not been looked at in this comparative way until recently. This is, in part, because the demands of infective and nutritional diseases on medical services have tended to overshadow the rheumatic diseases. This paper reviews the investigation of inflammatory rheumatic disease in Southern Africa. PMID:6884959

  4. Associations of MICA Polymorphisms with Inflammatory Rheumatic Diseases

    2015-01-01

    Inflammatory rheumatic diseases are characterized by inflammation resulting from the immune dysregulation that usually attacks joints, skin and internal organs. Many of them are considered as complex disease that may be predisposed by multiple genes and/or genetic loci, and triggered by environmental factors such as microbiome and cellular stress. The major histocompatibility complex class I chain-related gene A (MICA) is a highly polymorphic gene that encodes protein variants expressed under cellular stress conditions, and these MICA variants play important roles in immune activation and surveillance. Recently, accumulating evidences from both genetic and functional studies have suggested that MICA polymorphisms may be associated with various rheumatic diseases, and the expression of MICA variants may attribute to the altered immune responses in the diseases. The objective of this review is to discuss potential genetic associations and pathological relevance of MICA in inflammatory rheumatic diseases that may help us to understand pathogenesis contributing to the development of these diseases.

    2014-01-01

    Ankle involvement is frequent in patients with inflammatory rheumatic diseases, but accurate evaluation by physical examination is often difficult because of the complex anatomical structures of the ankle. Over the last decade, ultrasound (US) has become a practical imaging tool for the assessment of articular and periarticular pathologies, including joint synovitis, tenosynovitis, and enthesitis in rheumatic diseases. Progress in power Doppler (PD) technology has enabled evaluation of the strength of ongoing inflammation. PDUS is very useful for identifying the location and kind of pathologies in rheumatic ankles as well as for distinguishing between inflammatory processes and degenerative changes or between active inflammation and residual damage. The aim of this paper is to illustrate the US assessment of ankle lesions in patients with inflammatory rheumatic diseases, including rheumatoid arthritis, spondyloarthritis, and systemic lupus erythematosus, focusing on the utility of PDUS.

    Abstract The aim of this study was to determine whether inflammation is related to cancer development, and whether the incidence of cancer is increased and occurs in a site-specific manner in patients with systemic autoimmune rheumatic diseases (SARDs). This study included a nationwide dynamic cohort of patients with various newly diagnosed SARDs from 1997 to 2010 with follow-up until 2012. This study included 75,123 patients with SARDs. During 562,870 person-years of follow-up, 2844 patients developed cancer. Between 1997 and 2010, the highest number of newly diagnosed SARDs cases were rheumatoid arthritis (n = 35,182), followed by systemic lupus erythematosus (SLE, n = 15,623), Sjögren syndrome (n = 11,998), Kawasaki disease (n = 3469), inflammatory bowel disease (n = 2853), scleroderma (n = 1814), Behçet disease (n = 1620), dermatomyositis (n = 1119), polymyositis (n = 811), and vasculitis other than Kawasaki disease (n = 644). A significant standardized incidence ratio (SIR) of overall cancer was observed for patients with SLE (1.41; 95% confidence interval [CI], 1.28–1.56), Sjögren syndrome (1.19; 95% CI, 1.08–1.30), scleroderma (1.27; 95% CI, 1.02–1.59), dermatomyositis (4.79; 95% CI, 4.01–5.73), polymyositis (1.47; 95% CI, 1.05–2.06), vasculitis excluding Kawasaki disease (1.75; 95% CI, 1.20–2.55), and Kawasaki disease (2.88; 95% CI, 1.60–5.20). Overall, patients with most SARDs had a significantly higher risk of inflammation-associated site-specific cancers and hematologic malignancies. This study confirms that autoimmunity is associated with site-specific and hematological malignancies and provides clinical evidence of an association between inflammation and subsequent site-specific cancer development. These findings support the importance of inflammation in site-specific organ system carcinogenesis. PMID:27149461

    Chronic inflammatory and autoimmune conditions result from an interplay between genetic and environmental factors culminating in the phenotypes of established disease. The transition from health to established disease is relatively well understood in rheumatoid arthritis (RA), which provides an exemplar for other diseases. This article addresses terminologies to describe the phases of disease leading to RA, disease initiation and the point from which disease duration should be timed, the future research agenda suggested by this approach to the definition of phases of disease, and the importance of capturing the patient perspective in research into the earliest phases of disease.

    Vitamin D deficiency has been reported in patients with chronic inflammatory conditions, such as rheumatic and inflammatory bowel diseases (IBD). We evaluated the role of biologic therapy on vitamin D, calcium and parathormone (PTH) levels. This cross-sectional study enrolled consecutive patients with either rheumatic diseases or IBD who underwent an ambulatory visit. Patients receiving vitamin D/calcium supplementation were excluded. Vitamin D deficiency or insufficiency was diagnosed when values were <20 ng/mL and 21-29 ng/ml, respectively. Patients were sub-grouped according to biologic therapy. A multivariate analysis was performed. Two-hundred patients, including 136 with a rheumatic disease (M/F 37/99; mean age 60.7 ± 12.9 years) and 64 with IBD (M/F 41/23; Mean age 49.6 ± 13.1 years) were enrolled. Vitamin D deficiency/insufficiency was detected in as many as 63.5 % patients, being 61.8 and 67.2 % in patients with either rheumatic diseases or IBD, respectively. The prevalence of vitamin D deficiency/insufficiency was higher in those receiving biologics than other therapies (78.3 vs 43.2 %; p < 0.0001), in either rheumatic diseases (78.7 vs 41 %; p < 0.0001) or IBD (75 vs 50 %; p = 0.03) group. At multivariate analysis, only biologic therapy was independently associated with vitamin D deficit (OR 4.61; p = 0.001). Patients with vitamin D deficiency/insufficiency had hypocalcemia more frequently than controls (22.8 vs 10.9 %; p = 0.03), while PTH values did not differ significantly. This study finds that the prevalence of vitamin D deficiency/insufficiency was very high in patients with either rheumatic diseases or IBD receiving a biologic therapy. PMID:26939587

    Significantly decreased platelet serotonin contents were measured in rheumatoid arthritis, systemic lupus erythematosus (SLE), progressive systemic sclerosis, and mixed connective tissue disease. An inverse relationship between platelet serotonin levels and clinical disease activity was observed in both rheumatoid arthritis and systemic lupus erythematosus. SLE patients with multiple organ involvement showed the lowest platelet serotonin values. No correlation was observed between platelet serotonin contents and nonsteroidal antiinflammatory drug treatment, presence of circulating platelet reactive IgG, or the amount of circulating immune complexes. The results are interpreted as indicating platelet release occurring in vivo during inflammatory episodes of the rheumatic disorders investigated. PMID:6838676

    After two decades of research and development activity focussed on orally active kinase inhibitors, the first such drug (the JAK inhibitor Xeljanz, tofacitinib) was approved by the FDA in November 2012 for the treatment of rheumatoid arthritis (RA). There is an intense activity in many companies both on expanding the utility of JAK inhibitors in other auto-immune indications and in discovering inhibitors of the JAK family with different and more selective profiles. Progress is also being made with orally active Syk inhibitors. One such inhibitor (fostamatinib) is currently in large-scale phase 3 trials, and there are others in clinical development. The last two to three years have been transformative for kinase inhibitors in auto-immune diseases, as several inhibitors have finally progressed beyond phase 2 trials after so many failures on other targets. Thus, there are new treatment options for RA patients beyond existing oral DMARDs and parenteral biologics. PMID:23523202

    Yoga is a popular activity which may be well suited to some individuals with specific rheumatic disorders. Regular yoga practice can increase muscle strength and endurance, proprioception, and balance, with emphasis on movement through a full range of motion to increase flexibility and mobility. Additional beneficial elements of yoga include breathing, relaxation, body awareness, and meditation, which can reduce stress and anxiety and promote a sense of calmness, general well-being, and improved quality of life. Yoga also encourages a meditative focus, increased body awareness and mindfulness; some evidence suggests yoga may help reduce inflammatory mediators including C-reactive protein and interleukin-6. Yoga is best learned under the supervision of qualified teachers who are well informed about the potential musculoskeletal needs of each individual. Here, we briefly review the literature on yoga for healthy, musculoskeletal, and rheumatic disease populations and offer recommendations for discussing ways to begin yoga with patients.

    Macrophages belong to the innate immune system giving us protection against pathogens. However it is known that they are also involved in rheumatic diseases. Activated macrophages have two different phenotypes related to different stimuli: M1 (classically activated) and M2 (alternatively activated). M1 macrophages release high levels of pro-inflammatory cytokines, reactive nitrogen and oxygen intermediates killing microorganisms and tumor cells; while M2 macrophages are involved in resolution of inflammation through phagocytosis of apoptotic neutrophils, reduced production of pro-inflammatory cytokines, and increased synthesis of mediators important in tissue remodeling, angiogenesis, and wound repair. The role of macrophages in the different rheumatic diseases is different according to their M1/M2 macrophages phenotype. PMID:26929657

    In chronic inflammatory rheumatic diseases, comorbidities such as cardiovascular diseases and infections are suboptimally prevented, screened for and managed. The objective of this European League Against Rheumatism (EULAR) initiative was to propose points to consider to collect comorbidities in patients with chronic inflammatory rheumatic diseases. We also aimed to develop a pragmatic reporting form to foster the implementation of the points to consider. In accordance with the EULAR Standardised Operating Procedures, the process comprised (1) a systematic literature review of existing recommendations on reporting, screening for or preventing six selected comorbidities: ischaemic cardiovascular diseases, malignancies, infections, gastrointestinal diseases, osteoporosis and depression and (2) a consensus process involving 21 experts (ie, rheumatologists, patients, health professionals). Recommendations on how to treat the comorbidities were not included in the document as they vary across countries. The literature review retrieved 42 articles, most of which were recommendations for reporting or screening for comorbidities in the general population. The consensus process led to three overarching principles and 15 points to consider, related to the six comorbidities, with three sections: (1) reporting (ie, occurrence of the comorbidity and current treatments); (2) screening for disease (eg, mammography) or for risk factors (eg, smoking) and (3) prevention (eg, vaccination). A reporting form (93 questions) corresponding to a practical application of the points to consider was developed. Using an evidence-based approach followed by expert consensus, this EULAR initiative aims to improve the reporting and prevention of comorbidities in chronic inflammatory rheumatic diseases. Next steps include dissemination and implementation. PMID:26984008

    Patients with rheumatoid arthritis (RA) and other inflammatory joint diseases (IJDs) have an increased risk of premature death compared with the general population, mainly because of the risk of cardiovascular disease, which is similar in patients with RA and in those with diabetes mellitus. Pathogenic mechanisms and clinical expression of cardiovascular comorbidities vary greatly between different rheumatic diseases, but atherosclerosis seems to be associated with all IJDs. Traditional risk factors such as age, gender, dyslipidaemia, hypertension, smoking, obesity and diabetes mellitus, together with inflammation, are the main contributors to the increased cardiovascular risk in patients with IJDs. Although cardiovascular risk assessment should be part of routine care in such patients, no disease-specific models are currently available for this purpose. The main pillars of cardiovascular risk reduction are pharmacological and nonpharmacological management of cardiovascular risk factors, as well as tight control of disease activity. PMID:26282082

    Objective Severe myelosuppression is a serious concern in the management of rheumatic disease patients receiving methotrexate (MTX) therapy. This study was intended to explore factors associated with the development of MTX-related myelosuppression and its disease severity. Methods We retrospectively examined a total of 40 cases of MTX-related myelosuppression that had been filed in the registries of participating rheumatology and hematology divisions. Data before onset were compared with those of 120 controls matched for age and sex. Cytopenia was graded according to the National Cancer Institute criteria for adverse events. Data before and at onset were compared between the severe and non-severe groups. Results Non-use of folic acid supplements, concurrent medications, and low renal function were significantly associated with the development of myelosuppression (p < 0.001, p < 0.001, and p = 0.002, respectively). In addition, significantly lower MTX dosages, higher blood cell counts, and lower hemoglobin levels were seen in the myelosuppression group (p < 0.001). No patients exhibited leukocytopenia, neutropenia, or thrombocytopenia in routine blood monitoring taken within the past month. One-fourth developed myelosuppression within the first two months (an early-onset period). Myelosuppression was severe in approximately 40% of patients. Hypoalbuminemia and non-use of folic acid supplements were significantly associated with the severity of pancytopenia (p = 0.001 and 0.008, respectively). Besides these two factors, early onset and the use of lower doses of MTX were significantly associated with the severity of neutropenia (p = 0.003, 0.007, 0.003, and 0.002, respectively). Conclusions Myelosuppression can occur abruptly at any time during low-dose MTX therapy, but severe neutropenia is more likely to occur in the early-onset period of this therapy. Contrary to our expectations, disease severity was not dependent on MTX doses. Serum albumin levels and folic acid

    Acute rheumatic fever (ARF) is the result of an autoimmune response to pharyngitis caused by infection with group A Streptococcus. The long-term damage to cardiac valves caused by ARF, which can result from a single severe episode or from multiple recurrent episodes of the illness, is known as rheumatic heart disease (RHD) and is a notable cause of morbidity and mortality in resource-poor settings around the world. Although our understanding of disease pathogenesis has advanced in recent years, this has not led to dramatic improvements in diagnostic approaches, which are still reliant on clinical features using the Jones Criteria, or treatment practices. Indeed, penicillin has been the mainstay of treatment for decades and there is no other treatment that has been proven to alter the likelihood or the severity of RHD after an episode of ARF. Recent advances - including the use of echocardiographic diagnosis in those with ARF and in screening for early detection of RHD, progress in developing group A streptococcal vaccines and an increased focus on the lived experience of those with RHD and the need to improve quality of life - give cause for optimism that progress will be made in coming years against this neglected disease that affects populations around the world, but is a particular issue for those living in poverty.

    Rheumatic heart disease (RHD) is an inflammatory, autoimmune disease; occurring as a consequence of group A streptococcal infection complicated by rheumatic fever (RF). An inappropriate immune response is the central signature tune to the complex pathogenesis of RHD. However, some of those infected develop RHD, and genetic host susceptibility factors are thought to play a key role in diseasedevelopment. Therefore, the present study was designed to explore the role of genetic variants in inflammatory genes in conferring risk of RHD. The study recruited total of 700 subjects, including 400 RHD patients and 300 healthy controls. We examined the associations of 8 selected polymorphisms in seven inflammatory genes: IL-6 [rs1800795G/C], IL-10 [rs1800896G/A], TNF-A [rs1800629G/A], IL-1β [rs2853550C/T], IL-1VNTR [rs2234663], TGF-β1 [rs1800469C/T]; [rs1982073T/C], and CTLA-4 [rs5742909C/T] with RHD risk. Genotyping for all the polymorphisms was done using PCR-ARMS/PCR/RFLP methods. Multifactor dimensionality reduction and classification and regression tree approaches were combined with logistic regression to discover high-order gene-gene interactions in studiedgenes involved in RHD susceptibility.In univariate logistic regression analysis, we found significant association of variant-containing genotypes (CT&TT) of TGF-β1 869T/C [rs1982073]; [p=0.0.004 & 0.001, OR (95% CI)=1.65 (1.2-2.3) & 2.25 (1.4-3.6) respectively], variant genotype (CC) of IL-1β -511C/T [rs2853550]; [p=0.001, OR (95% CI)=2.33 (1.4-3.8)] and IL-1 VNTR [rs2234663]; [p=0.03, OR (95% CI)=5.25 (1.2-23.4)] SNPs with RHD risk. CART analysis revealed that individuals with the combined genotypes of TGF-β1T/C_ rs1982073 (CT/TT) and IL-1 β_ rs2853550 (CC) had significantly higher susceptibility for RHD [p=0.0005, OR (95% CI)=5.91 (2.9-12.5)]. In MDR analysis, TGF-β1 869T>C yielded the highest testing accuracy of 0.562. In conclusion, using multi-analytical approaches, our study revealed important role of TGF

    Biological drugs are the most rapidly growing group of medicinal agents. In addition to hormone and vaccine products, the significance of drugs produced using genetic engineering has increased in numerous indications, especially in oncology. Furthermore, they have significantly contributed to the treatment of inflammatory musculoskeletal as well as cutaneous and intestinal diseases. Their use is limited by parenteral administration, immunogenicity, uncertainty about possible severe adverse effects and especially the high price of the drugs. The cessation of patent protection of the original brand pharmaceuticals, and marketing of biosimilar drugs are expected to lower the prices of the original biological, as well. PMID:27017788

    Summary Radiological imaging plays a fundamental role in the diagnosis and monitoring of rheumatic diseases. The basic method of imaging is a classic X-ray picture, which for many years has been used as a single method for the recognition and evaluation of the effects of disease management. In today’s modern day treatment of rheumatic diseases, ultrasonography and magnetic resonance are more commonly performed for early detection of inflammatory changes in the region of soft tissue, subchondral bone and bone marrow. In spite of their usefulness and fundamental role in the diagnosis, X-ray still remains an essential tool in the diagnosis of rheumatoid arthritis in children and is complementary to today’s methods of imaging diagnostics. In clinical practice, X-ray imaging is still an important examination performed not only to recognize the disorders, but also to provide a differential diagnosis. It helps estimate disease progression and is used to monitor the effects of treatment and the development of possible complications. Differential diagnosis of rheumatic diseases is performed on the basis of localization and type of radiographic changes. The surrounding periarticular soft tissues, bone structures, joint space, with special attention to articular bone surfaces and epiphyses, are analyzed. The aim of this work is to describe characteristic inflammatory changes present on X-ray imaging typical for the most commonly diagnosed rheumatic diseases in children, such as juvenile idiopathic arthritis, systemic lupus erythematosus, systemic scleroderma, mixed connective tissue disease, juvenile dermatomyositis, juvenile spondyloarthropathy and systemic vascular disease.

    The relationship between pharyngeal infections, such as tonsillitis and pharyngitis, caused by group A beta-hemolytic streptococci (BHSA) and acute rheumatic fever (ARF) is a well-established fact confirmed by numerous studies carried out along the following lines: epidemiological, immunological, therapeutic, and prophylactic. The currently available data provide an opportunity to discuss the existence of «rheumatogenic» BHSA strains exhibiting a number of characteristic clinical and morphological properties. According to the current recommendations penicillins remain the means of first-line therapy for the treatment of acute forms of BHSA-induced tonsillitis and pharyngitis, whereas the macrolides should be applied only as the alternative medications in the patients with intolerance to beta-lactam antibiotics. This article contains characteristics of BHSA-carrier state and the principal indications for the prescription of antibiotics to the patients with these conditions. The key principle of secondary medicamental prophylaxis of acute respiratory infections are expounded along with the main fines of future research on the problems associated with BHSA-induced pharyngeal infections.

    Physical therapy remains an important tool in rheumatic disease treatment even though great strides have been made with chemotherapy. Much physical therapy is misused, however, and physicians should ensure that the exercises ordered for a patient do not contribute to joint deformity. Underwater exercise, heat therapy, traction, massage and splinting as well as a warm and sympathetic staff are all good aids in rehabilitating the rheumatic patient, but careful supervision is needed for maximum benefit.

    The aim of this study was to determine whether inflammation is related to cancer development, and whether the incidence of cancer is increased and occurs in a site-specific manner in patients with systemic autoimmune rheumatic diseases (SARDs).This study included a nationwide dynamic cohort of patients with various newly diagnosed SARDs from 1997 to 2010 with follow-up until 2012.This study included 75,123 patients with SARDs. During 562,870 person-years of follow-up, 2844 patients developed cancer. Between 1997 and 2010, the highest number of newly diagnosed SARDs cases were rheumatoid arthritis (n = 35,182), followed by systemic lupus erythematosus (SLE, n = 15,623), Sjögren syndrome (n = 11,998), Kawasaki disease (n = 3469), inflammatory bowel disease (n = 2853), scleroderma (n = 1814), Behçet disease (n = 1620), dermatomyositis (n = 1119), polymyositis (n = 811), and vasculitis other than Kawasaki disease (n = 644). A significant standardized incidence ratio (SIR) of overall cancer was observed for patients with SLE (1.41; 95% confidence interval [CI], 1.28-1.56), Sjögren syndrome (1.19; 95% CI, 1.08-1.30), scleroderma (1.27; 95% CI, 1.02-1.59), dermatomyositis (4.79; 95% CI, 4.01-5.73), polymyositis (1.47; 95% CI, 1.05-2.06), vasculitis excluding Kawasaki disease (1.75; 95% CI, 1.20-2.55), and Kawasaki disease (2.88; 95% CI, 1.60-5.20). Overall, patients with most SARDs had a significantly higher risk of inflammation-associated site-specific cancers and hematologic malignancies.This study confirms that autoimmunity is associated with site-specific and hematological malignancies and provides clinical evidence of an association between inflammation and subsequent site-specific cancer development. These findings support the importance of inflammation in site-specific organ system carcinogenesis. PMID:27149461

    The use of IVIG to treat a wide variety of immune-driven diseases has grown rapidly, although the mechanism of action is not completely understood. Increasing demand for IVIG coupled with concerns regarding potential transmissible agents has led to worldwide supply shortages. National agencies have therefore produced guidelines for its use, with the latest England and Wales guideline being published in 2011. Due to the rarity of the rheumatic diseases, the evidence for IVIG use has been shown to be lacking in some areas and promising in others. Conditions in which IVIG has been shown to have benefit include ITP, Guillain–Barré syndrome and chronic inflammatory demyelinating polyneuropathy occurring in the context of rheumatic disease, as well as in SLE, idiopathic inflammatory myopathies and ANCA-associated vasculitides. This review looks at current IVIG use and is designed to be an aid for rheumatologists when considering the use of IVIG in clinical practice. PMID:25406359

    Radiosynovectomy is a safe and repeatable treatment method of chronic synovitis with synovial overgrowth and refractory chronic or acute inflammatory joint effusion. It consist in the intraarticular administration of a radioactive isotope in the form of a colloid causing the extinguishing of active synovitis. The radiocolloid causes permanent irradiation of the synovium with beta ray electron beams, which ultimately leads to its fibrosis and extinguishes the inflammatory process destroying the joint. The main indications for radiosynovectomy include chronic and acute arthritis in the course of systemic diseases, intraarticular bleeding in hemorrhagic diatheses (hemophilia), selected cases of osteoarthritis, recurrent effusions following surgery, e.g. arthroplasty, or other iatrogenic post-surgery complications causing arthritis. Radiosynovectomy is also performed in pigmented villonodular synovitis and crystal synovitis. The most common method used to determine the eligibility for radiosynovectomy is an ultrasound, which shows the location and activity of the thickened synovium. The administration of a radiocolloid into the joint, sheath or bursa should also be performed under the control of the ultrasound image, as this ensures a precise location of the puncture needle and full control of the isotope administration process. Clinical efficacy of radiosynovectomy depends on the proper qualification of patients for the procedure. The success rate of radiosynovectomy in common indications is 65–80%. It is confirmed by the visualization of avascular (fibrotic) synovium in follow-up ultrasound tests. The aim of this article is to present techniques and indications for the radiosynovectomy treatment. PMID:26673861

    Musculoskeletal ultrasonography is now widely used by almost all rheumatologists thanks to an improvement in the quality of ultrasound unit and probe and to the systematic teaching of this imaging technique to the rheumatology fellows. Applications have broadened from the study of degenerative and mechanical diseases to inflammatory rheumatic diseases. Ultrasound is more sensitive than clinical examination. Power Doppler allows the direct visualisation of inflammation within the tissues. Finally, it is a prognostic tool helping the physician in the management of the disease. This review will focus on the value and applications of ultrasonography in the 2 most frequent rheumatic diseases: rheumatoid arthritis and spondyloarthritis. We will also give some recent data on the usefulness of this imaging technique in the study of musculoskeletal manifestations associated with connective tissue disease. PMID:24439720

    The human gut harbours a tremendously diverse and abundant microbial community that correlates with, and even modulates, many health-related processes. The mucosal interfaces are particularly active sites of microorganism-host interplay. Growing insight into the characteristic composition and functionality of the mucosal microbiota has revealed that the microbiota is involved in mucosal barrier integrity and immune function. This involvement affects proinflammatory and anti-inflammatory processes not only at the epithelial level, but also at remote sites such as the joints. Here, we review the role of the gut microbiota in shaping local and systemic immune responses and how disturbances in the host-microorganism interplay can potentially affect the development and progression of rheumatic diseases. Increasing our understanding of how to promote host-microorganism homeostasis could therefore reveal novel strategies for the prevention or alleviation of rheumatic disease. PMID:27305853

    2014-01-01

    Background Pediatric rheumatic diseases have a significant impact on children’s quality of life and family functioning. Disease control and management of the symptoms are important to minimize disability and pain. Specialist clinical nurses play a key role in supporting medical teams, recognizing poor disease control and the need for treatment changes, providing a resource to patients on treatment options and access to additional support and advice, and identifying best practices to achieve optimal outcomes for patients and their families. This highlights the importance of investigating follow-up telenursing (TN) consultations with experienced, specialist clinical nurses in rheumatology to provide this support to children and their families. Methods/Design This randomized crossover, experimental longitudinal study will compare the effects of standard care against a novel telenursing consultation on children’s and family outcomes. It will examine children below 16 years old, recently diagnosed with inflammatory rheumatic diseases, who attend the pediatric rheumatology outpatient clinic of a tertiary referral hospital in western Switzerland, and one of their parents. The telenursing consultation, at least once a month, by a qualified, experienced, specialist nurse in pediatric rheumatology will consist of providing affective support, health information, and aid to decision-making. Cox’s Interaction Model of Client Health Behavior serves as the theoretical framework for this study. The primary outcome measure is satisfaction and this will be assessed using mixed methods (quantitative and qualitative data). Secondary outcome measures include disease activity, quality of life, adherence to treatment, use of the telenursing service, and cost. We plan to enroll 56 children. Discussion The telenursing consultation is designed to support parents and children/adolescents during the course of the disease with regular follow-up. This project is novel because it is based

    Diseases such as degenerative or rheumatoid arthritis are accompanied by joint destruction. Clinically applied tissue engineering technologies like autologous chondrocyte implantation, matrix-assisted chondrocyte implantation, or in situ recruitment of bone marrow mesenchymal stem cells target the treatment of traumatic defects or of early osteoarthritis. Inflammatory conditions in the joint hamper the application of tissue engineering during chronic joint diseases. Here, most likely, cartilage formation is impaired and engineered neocartilage will be degraded. Based on the observations that mesenchymal stem cells (a) develop into joint tissues and (b) in vitro and in vivo show immunosuppressive and anti-inflammatory qualities indicating a transplant-protecting activity, these cells are prominent candidates for future tissue engineering approaches for the treatment of rheumatic diseases. Tissue engineering also provides highly organized three-dimensional in vitro culture models of human cells and their extracellular matrix for arthritis research. PMID:19232063

    The human genome comprises approximately 30000 genes needed for the formation and function of approximately 1 Million proteins in the human body. Differentiation leads to the deactivation of genes that are not needed in the specific tissues or cells. To regulate the cell specific gene expression in normal cells epigenetic modifications work in concert with genetic mechanisms. In contrast to genetic mutations, epigenetics encompasses the wide range of heritable changes in gene expression that do not result from alteration in the DNA sequence itself. A dysregulation of epigenetic modifications results in diseases such as cancer or autoimmune diseases. Since these epigenetic modifications of the DNA and the histones are reversible they are good targets for novel therapeutic intervention. PMID:21424428

    Social consequences of a disease constitute limitations in performing roles relating to working life as well as family and social life caused by the disease, mainly chronic. The aim of the study was to analyze the social consequences of rheumatic diseases in the aspect of disability pensions with respect to incapacity for work and quality of life. The occurrence of rheumatic diseases is related not only to increased risk of different types of organic changes, but above all disability. In Europe almost 50% of persons suffering from diseases of the musculoskeletal system who are currently unemployed were breadwinners. Nearly 60% of them received legal disability status. The loss of work ability is, among other things, the consequence of progressive disability. In Europe 40% of persons suffering from rheumatoid arthritis (RA) had to stop working due to the disease. Most of the persons diagnosed with RA were of working age. It results in the decrease in the quality of life as well as economic difficulties (decreased incomes and increased disease-related costs). In Poland the results of the analysis of the Social Insurance Institution (ZUS) of first-time disability recognition issued for the purpose of disability pensions in 2014 showed that the incapacity for work was caused by diseases relating to general health condition (65.5%). Diseases of the musculoskeletal system were the cause of partial inability to work of 21.6% of persons who received a disability pension for the first time (as many as 5,349 certificates were issued). Early diagnosis and implementation of effective treatment are the necessary conditions for a patient to sustain activity, both professional and social, which is of crucial importance to reduce the negative effects of the disease.

    Rheumatic fever (RF) and rheumatic heart disease (RHD) are the most-common cardiovascular disease in young people aged <25 years, globally. They are important contributors to cardiovascular morbidity and mortality in Bangladesh. Classical risk factors, i.e. poverty, overcrowding, ignorance, and insufficient health care services were responsible for the high incidence and prevalence of these diseases over the last century. In concert with the progresses in socioeconomic indicators, advances in health sectors, improved public awareness, and antibiotic prophylaxis, acute RF came into control. However, chronic RHD continues to be prevalent, and the actual disease burden may be much higher. RHD predominantly affects the young adults, seriously incapacitates them, follows a protracted course, gets complicated because of delayed diagnosis and is sometimes maltreated. The treatment is often palliative and expensive. Large-scale epidemiological and clinical researches are needed to formulate evidence-based national policy to tackle this important public health issue in future. PMID:26896274

    Fetal microchimerism is the presence of fetal cells inmaternal tissues and vice versa, i.e., the coexistence of2 different cellular populations from genetically differentindividuals within a single person. The most frequentcause of microchimerism is pregnancy, in which there is abi-directional fetal-maternal interchange of cells duringpregnancy and delivery. Fetal cells have been demonstrated in the tissues ofpatients with rheumatic, endocrine or infectious diseases,as well as in those of healthy individuals. Microchimerism has been most extensively studied insystemic sclerosis. It seems that during pregnancyallogenic fetal or maternal cells cross the placenta bidirectionallyand persist in the systemic circulation andtissues of both mother and child. Subsequently, they areactivated, resulting in is a graft-against-host reactionassociated with the onset of clinical manifestations.Microchimerism has been also studied in otherconnective tissue diseases.

    Risk for amyloidosis in rheumatic diseases is associated with a long-lasting inflammation. To assess possible changes in the incidence of terminal uraemia due to amyloidosis associated with rheumatic diseases on a nationwide basis, we scrutinised the files of the Finnish Registry for Kidney Diseases for patients suffering from amyloidosis associated with rheumatoid arthritis (RA), ankylosing spondylitis (AS) or juvenile idiopathic arthritis (JIA) over the period 1995-2008. The registry has an estimated 97-99% coverage of all patients accepted for renal replacement therapy (RRT) in the country. Data on the consumption of antirheumatic drugs were collected from two sources: the Social Insurance Institution's Drug Reimbursement Register, and the Sales Register of the National Agency for Medicines from the above period. Altogether 264 cases were identified. Two hundred twenty-nine of them had RA, 15 AS and 20 JIA. When the total annual number of new admissions to RRT varied between 20 and 37 at the end of 1990s, it was under half of that from 2002 onwards. Over this period, the number of users of low-dose methotrexate (MTX) has increased 3.6-fold, the drug being the most frequently used disease modifying anti-rheumatic drug in Finland. The present nationwide series is the first to show that the incidence of end-stage renal disease due to amyloidosis associated with rheumatic diseases is decreasing. An obvious reason for this is intensive anti-rheumatic drug therapy. PMID:21284495

    Disease activity refers to potentially reversible aspects of a disease. Measurement of disease activity in paediatric rheumatic diseases is a critical component of patient care and clinical research. Disease activity measures are developed systematically, often involving consensus methods. To be useful, a disease activity measure must be feasible, valid, and interpretable. There are several challenges in quantifying disease activity in paediatric rheumatology; namely, the conditions are multidimensional, the level of activity must be valuated in the context of treatment being received, there is no gold standard for disease activity, and it is often difficult to incorporate the patient's perspective of their disease activity. To date, core sets of response variables are defined for juvenile idiopathic arthritis, juvenile systemic lupus erythematosus, and juvenile dermatomyositis, as well as definitions for improvement in response to therapy. Several specific absolute disease activity measures also exist for each condition. Further work is required to determine the optimal disease activity measures in paediatric rheumatology.

    The human microbiome consists of the total diversity of microbiota and their genes. High-throughput sequencing has allowed for inexpensive and rapid evaluation of taxonomic representation and functional capability of the microbiomes of human body sites. Autoimmune and inflammatory rheumatic diseases are characterized by dysbiosis of the microbiome. Microbiome dysbiosis can be influenced by host genetics and environmental factors. Dysbiosis is also associated with shifts in certain functional pathways. The goal of this article is to provide a current and comprehensive review of the unique characteristics of the microbiome of patients with autoimmune and inflammatory rheumatic diseases, measured using high-throughput sequencing. We also highlight the need for broader studies utilizing a longitudinal approach to better understand how the human microbiome contributes to disease susceptibility, and to characterize the role of the interaction between host genetics and microbial diversity in the pathogenesis of autoimmune diseases, disease manifestations, and progression.

    Rates of acute rheumatic fever and chronic rheumatic heart disease in Aboriginal people, Torres Strait Islanders and Māori continue to be unacceptably high. The impact of rheumatic heart disease is inequitable on these populations as compared with other Australians and New Zealanders. The associated cardiac morbidity, including the development of rheumatic valve disease, and cardiomyopathy, with possible sequelae of heart failure, development of atrial fibrillation, systemic embolism, transient ischaemic attacks, strokes, endocarditis, the need for interventions including cardiac surgery, and impaired quality of life, and shortened life expectancy, has major implications for the individual. The adverse health and social effects may significantly limit education and employment opportunities and increase dependency on welfare. Additionally there may be major adverse impacts on family and community life. The costs in financial terms and missed opportunities, including wasted young lives, are substantial. Prevention of acute rheumatic fever is dependent on the timely diagnosis and treatment of sore throats and skin infections in high-risk groups. Both Australia and New Zealand have registries for acute rheumatic fever but paradoxically neither includes all cases of chronic rheumatic heart disease many of whom would benefit from close surveillance and follow-up. In New Zealand and some Australian States there are programs to give secondary prophylaxis with penicillin, but these are not universal. Surgical outcomes for patients with rheumatic valvular disease are better for valve repair than for valve replacement. Special attention to the selection of the appropriate valve surgery and valve choice is required in pregnant women. It may be necessary to have designated surgical units managing Indigenous patients to ensure high rates of surgical repair rather than valve replacement. Surgical guidelines may be helpful.

    A double monoclonal immunoradiometric assay specific for bone alkaline phosphatase (BAP) was used to determine whether the raised total alkaline phosphatase (TAP) often found in patients with active rheumatoid arthritis (RA) and ankylosing spondylitis (AS) is derived from bone or liver. Fifty-eight patients with RA were compared to 14 with AS and 14 with non-inflammatory rheumatic diseases (NI). None had clinical liver disease and only one had a slightly elevated aspartate transaminase activity. Elevated BAP concentrations were found in seven patients (5 RA, 1 AS, 1 NI), only two of whom also had abnormal TAP. Abnormal TAP activities were found in only three patients (all RA). BAP did not correlate with disease activity in RA or AS. In contrast, TAP correlated with disease activity (assessed by plasma viscosity) in RA (P < 0.002) and gamma-glutamyl transferase (GGT) also correlated with plasma viscosity in RA (P < 0.01). Both TAP and BAP were significantly correlated with GGT in RA (P < 0.001 and P < 0.02, respectively). These findings are discussed, together with possible reasons for the conflicting nature of some of the observations. PMID:7486797

    Chronic inflammatory rheumatic diseases (CIRDs) are immune-mediated pathologies involving joints. To date, TNFα-blocking agents administration is the most promising therapy, although these treatments are associated with an increased Polyomavirus JC (JCPyV) reactivation, the etiological agent of the Progressive Multifocal Leukoencephalopathy (PML). The aim of this study was the recruitment and the analysis of a CIRDs cohort in order to investigate a possible correlation between JCPyV presence and the influence of anti-TNF-α agents on viral loads. Blood and urine samples were collected from 34 CIRDs subjects prior the first anti-TNF-α infusion (T0) and after 3 (T3), 6 (T6), 12 (T12), and 18 (T18) months. Results showed persistent JC viruria significantly higher than JC viremia throughout the 18 month follow-up study (p = 0.002). In JCPyV positive samples, the non-coding control region (NCCR) was analyzed. Results evidenced archetypal structures (type II-S) in all isolates with the exception of a sequence isolated from a plasma sample, that corresponds to the type II-R found in PML subjects. Finally, the viral protein 1 (VP1) genotyping was performed and results showed the prevalence of the European genotypes 1A, 1B, and 4. Since only few studies have been carried out to understand whether there is a PML risk in CIRDs population infected by JCPyV, this study contributes to enrich literature insight on JCPyV biology in this cluster. Further investigations are necessary in order to recognize the real impact of biologics on JCPyV life cycle and to identify possible and specific viral variants related to increased virulence in CIRDs patients.

    Infections are one of the leading causes of morbidity and mortality in patients with rheumatic diseases. Although bacterial pathogens are the most common cause of infections, a wide variety of viral pathogens can also cause serious clinical manifestations mostly due to immunosupressive therapy primarily targeting cellular immunity (steroids, cyclosporins, cyclophosphamid, leflunomid, TNF-alfa antagonists etc.). Depleted cellular immunity can lead to reactivation of latent viruses such as members of Herpesvirus family, or hepatitis B and C viruses. Symptoms of viral infection may mimic exacerbation of rheumatic disease. In this paper authors present the main clinical characteristics, diagnostics and tretment possibilities for most common viral infections in immunosupressed host with a rheumatic disease.

    Rheumatoid Arthritis is a chronic autoimmune disease with a complex disease pathogenesis leading to inflammation and destruction of synovial tissue in the joint. Several molecules lead to activation of immune pathways, including autoantibodies, Toll-Like Receptor ligands and cytokines. These pathways can cooperate to create the pro-inflammatory environment that results in tissue destruction. Each of these pathways can activate mast cells, inducing the release of a variety of inflammatory mediators, and in combination can markedly enhance mast cell responses. Mast cell-derived cytokines, chemokines, and proteases have the potential to induce recruitment of other leukocytes able to evoke tissue remodeling or destruction. Likewise, mast cells can secrete a plethora of factors that can contribute to tissue remodeling and fibroblast activation. Although the functional role of mast cells in arthritis pathogenesis in mice is not yet elucidated, the increased numbers of mast cells and mast cell-specific mediators in synovial tissue of rheumatoid arthritis patients suggest that mast cell activation in rheumatoid arthritis may contribute to its pathogenesis.

    Gingivitis and periodontitis are immunoinflammatory periodontal diseases characterized by chronic localized infections usually associated with insidious inflammation This narrative review discusses periodontal diseases and mechanisms influencing the immune response and autoimmunity in pediatric rheumatic diseases (PRD), particularly juvenile idiopathic arthritis (JIA), childhood-onset systemic lupus erythematosus (C-SLE) and juvenile dermatomyositis (JDM). Gingivitis was more frequently observed in these diseases compared to health controls, whereas periodontitis was a rare finding. In JIA patients, gingivitis and periodontitis were related to mechanical factors, chronic arthritis with functional disability, dysregulation of the immunoinflammatory response, diet and drugs, mainly corticosteroids and cyclosporine. In C-SLE, gingivitis was associated with longer disease period, high doses of corticosteroids, B-cell hyperactivation and immunoglobulin G elevation. There are scarce data on periodontal diseases in JDM population, and a unique gingival pattern, characterized by gingival erythema, capillary dilation and bush-loop formation, was observed in active patients. In conclusion, gingivitis was the most common periodontal disease in PRD. The observed association with disease activity reinforces the need for future studies to determine if resolution of this complication will influence disease course or severity. PMID:25627227

    The role of Interleukin(IL)-6 in the pathogenesis of joint and systemic inflammation in rheumatoid arthritis (RA) and systemic juvenile idiopathic arthritis (s-JIA) has been clearly demonstrated. However, the mechanisms by which IL-6 contributes to the pathogenesis are not completely understood. This study investigates whether IL-6 affects, alone or upon toll like receptor (TLR) ligand stimulation, the production of inflammatory cytokines and chemokines in human peripheral blood mononuclear cells (PBMCs), synovial fluid mononuclear cells from JIA patients (SFMCs) and fibroblast-like synoviocytes from rheumatoid arthritis patients (RA synoviocytes) and signalling pathways involved. PBMCs were pre-treated with IL-6 and soluble IL-6 Receptor (sIL-6R). SFMCs and RA synoviocytes were pre-treated with IL-6/sIL-6R or sIL-6R, alone or in combination with Tocilizumab (TCZ). Cells were stimulated with LPS, S100A8-9, poly(I-C), CpG, Pam2CSK4, MDP, IL-1β. Treatment of PBMCs with IL-6 induced production of TNF-α, CXCL8, and CCL2, but not IL-1β. Addition of IL-6 to the same cells after stimulation with poly(I-C), CpG, Pam2CSK4, and MDP induced a significant increase in IL-1β and CXCL8, but not TNF-α production compared with TLR ligands alone. This enhanced production of IL-1β and CXCL8 paralleled increased p65 NF-κB activation. In contrast, addition of IL-6 to PBMCs stimulated with LPS or S100A8-9 (TLR-4 ligands) led to reduction of IL-1β, TNF-α and CXCL8 with reduced p65 NF-κB activation. IL-6/IL-1β co-stimulation increased CXCL8, CCL2 and IL-6 production. Addition of IL-6 to SFMCs stimulated with LPS or S100A8 increased CXCL8, CCL2 and IL-1β production. Treatment of RA synoviocytes with sIL-6R increased IL-6, CXCL8 and CCL2 production, with increased STAT3 and p65 NF-κB phosphorylation. Our results suggest that IL-6 amplifies TLR-induced inflammatory response. This effect may be relevant in the presence of high IL-6 and sIL-6R levels, such as in arthritic joints

    Patient: Male, 76 Final Diagnosis: Rheumatic valvular heart disease Symptoms: Breathlessness and leg edema Medication: — Clinical Procedure: Medical treatment for heart failure Specialty: Cardiology Objective: Rare disease Background: Complete calcification of the left atrium (LA) is called “coconut atrium”, which decreases the compliance of LA, leading to the elevation of LA pressure that is transmitted to the right-side of the heart. The pathogenesis of LA calcification in patients with rheumatic heart disease is unknown; however, possible mechanisms include chronic strain force in the atrial wall and inflammation. We report here a patient with long-standing rheumatic valvular heart disease with coconut atrium. Case Report: A 76-year-old man presented with breathlessness and leg edema due to right-sided heart failure. He was diagnosed with rheumatic fever at 8 years of age. Mitral commissurotomy and the mitral and aortic valve replacement were previously performed to treat mitral and aortic valvular stenosis. The profile view of the chest X-ray indicated a diffuse calcified outline of the LA wall. A transthoracic echocardiogram revealed pulmonary hyper-tension and dilatation of both atria. Moreover, computed tomography showed nearly circumferential calcification of the LA wall. Despite intense medical treatment, he succumbed to heart failure. An autopsy demonstrated that the LA was markedly dilated, its wall was calcified, and its appearance was similar to the surface of an atherosclerotic aorta. Microscopic examination revealed intensive calcification in the endocardium. Minimal accumulation of inflammatory cells was noted. Although slight fibrosis was observed, the cardiac musculature was preserved. Conclusions: To the best of our knowledge, this is the first report that identifies the histological changes of LA calcification associated with long-standing rheumatic valvular heart disease.

  13. Autophagy: controlling cell fate in rheumatic diseases.

    Autophagy, an endogenous process necessary for the turnover of organelles, maintains cellular homeostasis and directs cell fate. Alterations to the regulation of autophagy contribute to the progression of various rheumatic diseases, including systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), osteoarthritis (OA) and systemic sclerosis (SSc). Implicit in the progression of these diseases are cell-type-specific responses to surrounding factors that alter autophagy: chondrocytes within articular cartilage show decreased autophagy in OA, leading to rapid cell death and cartilage degeneration; fibroblasts from patients with SSc have restricted autophagy, similar to that seen in aged dermal fibroblasts; fibroblast-like synoviocytes from RA joints show altered autophagy, which contributes to synovial hyperplasia; and dysregulation of autophagy in haematopoietic lineage cells alters their function and maturation in SLE. Various upstream mechanisms also contribute to these diseases by regulating autophagy as part of their signalling cascades. In this Review, we discuss the links between autophagy, immune responses, fibrosis and cellular fates as they relate to pathologies associated with rheumatic diseases. Therapies in clinical use, and in preclinical or clinical development, are also discussed in relation to their effects on autophagy in rheumatic diseases. PMID:27334205

    Rheumatic heart disease, already a major burden in low- and middle-income countries, is becoming an emerging problem in high-income countries. Although acute rheumatic fever and rheumatic heart disease have almost been eradicated in areas with established economies, the emergence of this problem may be attributable to the migration from low-income to high-income settings. Between 2010 and 2012, we diagnosed a cluster of rheumatic heart disease cases in children from the Middle Tennessee area. The goal of this report is to increase awareness among clinicians as the incidence and prevalence of acute rheumatic fever remain relatively significant in large US metropolitan areas. Although acute rheumatic fever is seasonal, a high suspicion index may lead to the early diagnosis and prevention of its cardiac complications. Furthermore, screening procedures may be recommended for populations at risk for rheumatic heart disease in endemic areas, and active surveillance with echocardiography-based screening might become very important.

    Pregnancy can create a challenge for physicians caring for women with rheumatic diseases. For many women with rheumatoid arthritis (RA), pregnancy can provide a reprieve from long-term joint pain and inflammation, but others will not experience remission and will continue to need medication. Systemic lupus erythematosus (SLE) may remain quiet in some women, but in others may become more aggressive during pregnancy, putting both mother and foetus at risk. Women with limited scleroderma can do remarkably well, but scleroderma renal crises can be difficult to manage. A third of pregnancies in women with antiphospholipid syndrome (APS) may be refractory to our best therapy. In general, active inflammation from rheumatic diseases poses a stronger threat to the well-being of both mother and foetus than many immunosuppressant medications. Therefore, continued immunosuppression with the least risky medications will allow for the most optimal pregnancy outcomes. PMID:20337545

    Various autoimmune rheumatic diseases (ARDs), including rheumatoid arthritis, spondyloarthritis, vasculitis and systemic lupus erythematosus, are associated with premature atherosclerosis. However, premature atherosclerosis has not been uniformly observed in systemic sclerosis. Furthermore, although experimental models of atherosclerosis support the role of antiphospholipid antibodies in atherosclerosis, there is no clear evidence of premature atherosclerosis in antiphospholipid syndrome (APA). Ischemic events in APA are more likely to be caused by pro-thrombotic state than by enhanced atherosclerosis. Cardiovascular disease (CVD) in ARDs is caused by traditional and non-traditional risk factors. Besides other factors, inflammation and immunologic abnormalities, the quantity and quality of lipoproteins, hypertension, insulin resistance/hyperglycemia, obesity and underweight, presence of platelets bearing complement protein C4d, reduced number and function of endothelial progenitor cells, apoptosis of endothelial cells, epigenetic mechanisms, renal disease, periodontal disease, depression, hyperuricemia, hypothyroidism, sleep apnea and vitamin D deficiency may contribute to the premature CVD. Although most research has focused on systemic inflammation, vascular inflammation may play a crucial role in the premature CVD in ARDs. It may be involved in the development and destabilization of both atherosclerotic lesions and of aortic aneurysms (a known complication of ARDs). Inflammation in subintimal vascular and perivascular layers appears to frequently occur in CVD, with a higher frequency in ARD than in non-ARD patients. It is possible that this inflammation is caused by infections and/or autoimmunity, which might have consequences for treatment. Importantly, drugs targeting immunologic factors participating in the subintimal inflammation (e.g., T- and B-cells) might have a protective effect on CVD. Interestingly, vasa vasorum and cardiovascular adipose tissue may

    There is a growing understanding of the mechanisms by which the influence of the microbiota projects beyond sites of primary mucosal occupation to other human body systems. Bacteria present in the intestinal tract exert a profound effect on the host immune system, both locally and at distant sites. The oral cavity has its own characteristic microbiota, which concentrates in periodontal tissues and is in close association with a permeable epithelium. In this review we examine evidence which supports a role for the microbiome in the aetiology of rheumatic disease. We also discuss how changes in the composition of the microbiota, particularly within the gastrointestinal tract, may be affected by genetics, diet, and use of antimicrobial agents. Evidence is presented to support the theory that an altered microbiota is a factor in the initiation and perpetuation of inflammatory diseases, including rheumatoid arthritis (RA), spondyloarthritis (SpA), and inflammatory bowel disease (IBD). Mechanisms through which the microbiota may be involved in the pathogenesis of these diseases include altered epithelial and mucosal permeability, loss of immune tolerance to components of the indigenous microbiota, and trafficking of both activated immune cells and antigenic material to the joints. The potential to manipulate the microbiome, by application of probiotics and faecal microbial transplant (FMT), is now being investigated. Both approaches are in their infancy with regard to management of rheumatic disease but their potential is worthy of consideration, given the need for novel therapeutic approaches, and the emerging recognition of the importance of microbial interactions with human hosts.

    Immunoglobulins (Igs) and autoantibodies are commonly tested in sera from patients with suspected rheumatic disease. To evaluate the clinical utility of the tests in combination, we investigated sera from 351 patients with autoimmune rheumatic disease (ARD) rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and Sjögren's syndrome (SS) and 96 patients with nonautoimmune rheumatic disease (NAD) (fibromyalgia, osteoarthritis, etc.). Antinuclear antibodies (ANA), rheumatoid factor (RF), antibodies against DNA and extractable nuclear antigens (anti-ENA), IgG, IgA and IgM were measured for all patients. Logistic regression analysis of test results was used to calculate each patient's probability for belonging to the ARD or NAD group as well as likelihood ratios for disease. Test accuracy was investigated using receiver-operating characteristic (ROC) plots and nonparametric ROC analysis. Neither concentrations of IgG, IgA, IgM, anti-DNA nor anti-ENA gave a significant effect on diagnostic outcome. Probabilities for disease and likelihood ratios calculated by combining RF and ANA performed significantly better at predicting ARD than utilization of the diagnostic tests in isolation (P < 0.001). At a cut-off level of P = 0.73 and likelihood ratio = 1, the logistic model gave a specificity of 93% and a sensitivity of 75% for the differentiation between ARD and NAD. When compared at the same level of specificity, ANA gave a sensitivity of 37% and RF gave a sensitivity of 56.6%. Dichotomizing ANA and RF as positive or negative did not reduce the performance characteristics of the model. Combining results obtained from serological analysis of ANA and RF according to this model will increase the diagnostic utility of the tests in rheumatological practice. PMID:12828565

    We tried to establish the efficiency of low energy (power) lasers (LEL), in various inflammatory and noninflammatory rheumatic diseases during five years. We treated 514 patients with osteoarthrosis, 326 patients with nonarticular rheumatism and 82 patients with inflammatory rheumatism, in four different ways: only with Galium-Aluminum-Arsenide (GaAs) infrared lasers; both GaAs lasers and Helium neon (HeNe) lasers; with placebo laser; with classical anti-inflammatory therapy. The results were analyzed using local objective improvements and the score obtained from a pain scale before and after the treatments. We also note some preliminary results obtained by the computer analysis of the evocated potentials after laser irradiation. We conclude that LEL (especially HeNe with GaAs) is obviously more efficient than placebo laser therapy and also had better or at least similar results, in most of the cases, than classical anti-inflammatory therapy.

    Throughout the last decade, increasing awareness has been raised on issues related to reproduction in rheumatic diseases including basic research to clarify the important role of estrogens in the etiology and pathophysiology of immune/inflammatory diseases. Sub- or infertility is a heterogeneous condition that can be related to immunological mechanisms, to pregnancy loss, to disease burden, to therapy, and to choices in regard to family size. Progress in reproductive medicine has made it possible for more patients with rheumatic disease to have children. Active disease in women with rheumatoid arthritis (RA) affects their children's birth weight and may have long-term effects on their future health status. Pregnancy complications as preeclampsia and intrauterine growth restriction are still increased in patients with systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS), however, biomarkers can monitor adverse events, and several new therapies may improve outcomes. Pregnancies in women with APS remain a challenge, and better therapies for the obstetric APS are needed. New prospective studies indicate improved outcomes for pregnancies in women with rare diseases like systemic sclerosis and vasculitis. TNF inhibitors hold promise for maintaining remission in rheumatological patients and may be continued at least in the first half of pregnancy. Pre-conceptional counseling and interdisciplinary management of pregnancies are essential for ensuring optimal pregnancy outcomes. PMID:25555818

    Rheumatic heart disease, a neglected disease, continues to be a burden in India and other developing countries. It is a result of an autoimmune sequalae in response to group A beta hemolytic streptococcus (GAS) infection of the pharynx. Acute rheumatic fever (RF), a multisystem inflammatory disease, is followed by rheumatic heart disease (RHD) and has manifestations of joints, skin and central nervous system involvement. A review of epidemiological studies indicates unchanged GAS pharyngitis and carrier rates in India. The apparent decline in RHD rates in India as indicated by the epidemiological studies has to be taken with caution as methodological differences exist among studies. Use of echocardiography increases case detection rates of RHD in population surveys. However, the significance of echo based diagnosis of carditis needs further evaluation to establish the significance. Research in this area through prospective follow up studies will have to be undertaken by the developing countries as the interest of developed countries in the disease has waned due the declined burden in their populations. Prevention of RHD is possible through treatment of GAS pharyngitis (primary prophylaxis) and continued antibiotic treatment for number of years in patients with history of RF to prevent recurrences (secondary prophylaxis). The cost effectiveness and practicality of secondary prophylaxis is well documented. The challenge to any secondary prophylaxis program for prevention of RF in India will be the availability of benzathine penicillin G and dissipation of fears of allergic reactions to penicillin among practitioners, general public and policy makers. The authors review here the progress and challenges in epidemiology, diagnosis and primary and secondary prevention of RF and RHD. PMID:22941214

    The identification of modifiable risk factors for the development of rheumatic conditions and their sequelae is crucial for reducing the substantial worldwide burden of these diseases. However, the validity of such research can be threatened by sources of bias, including confounding, measurement and selection biases. In this Review, we discuss potentially major issues of selection bias—a type of bias frequently overshadowed by other bias and feasibility issues, despite being equally or more problematic—in key areas of rheumatic disease research. We present index event bias (a type of selection bias) as one of the potentially unifying reasons behind some unexpected findings, such as the ‘risk factor paradox’—a phenomenon exemplified by the discrepant effects of certain risk factors on the development versus the progression of osteoarthritis (OA) or rheumatoid arthritis (RA). We also discuss potential selection biases owing to differential loss to follow-up in RA and OA research, as well as those due to the depletion of susceptibles (prevalent user bias) and immortal time bias. The lesson remains that selection bias can be ubiquitous and, therefore, has the potential to lead the field astray. Thus, we conclude with suggestions to help investigators avoid such issues and limit the impact on future rheumatology research. PMID:24686510

These molecules, which include amino acids, carbohydrates, lipids, nucleotides and their metabolites, can be detected quantitatively. Metabolomic methods, often focused on the information-rich analytical techniques of NMR spectroscopy and mass spectrometry, have potential for early diagnosis, monitoring therapy and defining disease pathogenesis in many therapeutic areas, including rheumatic diseases. By performing global metabolite profiling, also known as untargeted metabolomics, new discoveries linking cellular pathways to biological mechanisms are being revealed and are shaping our understanding of cell biology, physiology and medicine. These pathways can potentially be targeted to diagnose and treat patients with immune-mediated diseases. PMID:26935283

    Most individuals seeking consultation at sports medicine clinics are young, healthy athletes with injuries related to a specific activity. However, these athletes may have other systemic pathologies, such as rheumatic diseases, that may initially mimic sports-related injuries. As rheumatic diseases often affect the musculoskeletal system, they may masquerade as traumatic or mechanical conditions. A systematic review of the literature found numerous case reports of athletes who presented with apparent mechanical low back pain, sciatica pain, hip pain, meniscal tear, ankle sprain, rotator cuff syndrome and stress fractures and who, on further investigation, were found to have manifestations of rheumatic diseases. Common systemic, inflammatory causes of these musculoskeletal complaints include ankylosing spondylitis (AS), gout, chondrocalcinosis, psoriatic enthesopathy and early rheumatoid arthritis (RA). Low back pain is often mechanical among athletes, but cases have been described where spondyloarthritis, especially AS, has been diagnosed. Neck pain, another common mechanical symptom in athletes, can be an atypical presentation of AS or early RA. Hip or groin pain is frequently related to injuries in the hip joint and its surrounding structures. However, differential diagnosis should be made with AS, RA, gout, psudeogout, and less often with haemochromatosis and synovial chondochromatosis. In athletes presenting with peripheral arthropathy, it is mandatory to investigate autoimmune arthritis (AS, RA, juvenile idiopathic arthritis and systemic lupus erythematosus), crystal-induced arthritis, Lyme disease and pigmented villonodular synovitis. Musculoskeletal soft tissue disorders (bursitis, tendinopathies, enthesitis and carpal tunnel syndrome) are a frequent cause of pain and disability in both competitive and recreational athletes, and are related to acute injuries or overuse. However, these disorders may occasionally be a manifestation of RA, spondyloarthritis

    Impaired programmed cell death is an important contributing mechanism in the development of chronic inflammatory and autoimmune diseases. Overexpression of Bcl-2 family proteins in such diseases has led to the concept of targeted suppression of these proteins as a primary therapeutic strategy. However, limited success with this approach has prompted pharmacologists to look at the other side of the coin, with the aim of reactivating jeopardized pro-apoptotic proteins that may neutralize Bcl-2 or other anti-apoptotic molecules. In this effort, BH3-only proteins have gained recent attention as endogenous molecules for the sensitization of resistant cells to undergo apoptosis. Among the BH3-only family, Noxa stands out as exceptional for its specificity to bind Mcl-1 and Bcl-2 and blunt their biological properties. Noxa is now being tested as a promising therapeutic target in cancer biology. Nonetheless, its role and clinical application still lack validation in autoimmune diseases, including rheumatic conditions. This is partly attributed to the significant gap in our understanding of its regulatory role and how either overexpression of Noxa or delivery of BH3 mimetics could be therapeutically exploited. In this review we highlight some recent studies in RA, OA, SLE and SS suggesting that Noxa may be used as a potential therapeutic target to circumvent invasive and tissue destructive processes in these rheumatic diseases.

    Spleen tyrosine kinase (Syk) is a member of the Src family of non-receptor tyrosine kinases, which associates directly with surface receptors, including B-cell receptor and Fcγ receptor, and is involved in a variety of signal transduction pathways. Rheumatoid arthritis (RA) and systemic lupus erythematosus are autoimmune diseases in which autoantibodies, immune complexes, and autoreactive T cells account for the expression of tissue inflammation and damage. Syk inhibitors efficiently suppress RA in patients albeit in the expression of unwanted side effects, including gastrointestinal effects, hypertension, and neutropenia. Syk inhibitors also inhibit clinical manifestations in lupus-prone mice. Here, we review the evidence that supports the use of Syk inhibitors to treat rheumatic and other autoimmune diseases.

    Vitiligo is a chronic disease characterized by the dysfunction or destruction of melanocytes with secondary depigmentation. The aim of the present study was to determine the prevalence of vitiligo associated with autoimmune rheumatic diseases. The clinical records from a 10-year database of patients with rheumatic diseases and associated vitiligo was analysed, with one group of patients having autoimmune rheumatic disease and another non-autoimmune rheumatic disease. Available serum samples were used to assess the anti-melanocyte antibodies. A total of 5,251 individual clinical files were archived in the last 10 years, and these patients underwent multiple rheumatology consultations, with 0.3% of the group presenting with vitiligo. The prevalence of vitiligo in the autoimmune rheumatic disease group was 0.672%, which was mainly associated with lupus and arthritis. However, patients with more than one autoimmune disease had an increased relative risk to develop vitiligo, and anti-melanocyte antibodies were positive in 92% of these patients. By contrast, the prevalence was 0.082% in the group that lacked autoimmune rheumatic disease and had negative autoantibodies. In conclusion, the association between vitiligo and autoimmune rheumatic diseases was relatively low. However, the relative risk increased when there were other autoimmune comorbidities, such as thyroiditis or celiac disease. Therefore, the presence of multiple autoimmune syndromes should be suspected. PMID:27446537

    The cloning of leptin in 1994 by Zhang et al. introduced a novel concept about white adipose tissue (WAT) as a very dynamic organ that releases a plethora of immune and inflammatory mediators, such as adipokines and cytokines, which are involved in multiple diseases. Actually, adipokines exert potent modulatory actions on target tissues involved in rheumatic diseases including cartilage, synovial, bone and immune cells. The goal of this paper is to elucidate the recent findings concerning the involvement of adipokines in rheumatic diseases, such as rheumatoid arthritis (RA), osteoarthritis (OA), and systemic lupus erythematosus (SLE).

    Systemic inflammatory rheumatic diseases are considered as autoimmune diseases, meaning that the balance between recognition of pathogens and avoidance of self-attack is impaired and the immune system attacks and destroys its own healthy tissue. Treatment with conventional Disease Modifying Antirheumatic Drugs (DMARDs) and/or Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) is often associated with various adverse reactions due to unspecific and toxic properties of those drugs.

    Microparticles (MPs) are small membrane-bound vesicles that arise from activated and dying cells and enter the blood to display pro-inflammatory and pro-thrombotic activities. MPs are 0.1–1.0 μm in size and incorporate nuclear, cytoplasmic and membrane molecules as they detach from cells. This process can occur with cell activation as well as cell death, with particles likely corresponding to blebs that form on the cell surface during apoptosis. To measure particle expression, flow cytometry allows determination of particle numbers based on size as well as surface markers that denote the cell of origin; platelet MPs are usually the most abundant type in blood. As shown in in vitro and in vivo systems, MPs can promote inflammation and thrombosis resulting from their content of cytokines like IL-1 and pro-coagulant molecules like tissue factor. Certain particle types can be anti-inflammatory, however, suggesting a range of immunomodulatory activities depending on the cell of origin. Studies on patients with a wide range of rheumatic disease show increased MP numbers in blood, with platelet and endothelial particles associated with vascular manifestations; increased numbers of particles also occur in the joint fluid where they may drive cytokine production and activate synoviocytes. In autoimmune diseases such as SLE and RA, MPs may also contribute to disease pathogenesis by the formation of immune complexes. MPs thus represent novel subcellular structures that can impact on the pathogenesis of rheumatic disease and serve as biomarkers of underlying cellular disturbances. PMID:22403183

    Protection against microbial attack or invasion is a fundamental function of the immune system. Crucial to this function is the ability to distinguish "self" from the invading organism, and tolerate "self" while removing "non-self". The ability to distinguish self from non-self is not inherent in the immune system, but rather is acquired and continuously maintained. Unfortunately, the mechanisms maintaining self-tolerance are not perfect, and at times break down. In these instances an autoimmune disease results. T cells initiate normal immune responses, and it is now clear that T cells can also initiate pathologic immune responses. In animal models, T cells produce diseases resembling rheumatoid arthritis (RA) (1-3), systemic lupus erythematosus (4-6) and progressive systemic sclerosis (7,8). It is likely that T cells participate in human autoimmune diseases as well. The molecular basis of T cell antigen recognition has been clarified over the past decade. These advances now allow direct examination of the T cell receptor (TCR) molecules participating in autoimmune responses, and raise the exciting possibility that the cells inducing autoimmune responses may finally be identified. Selective agents might then be developed which would interfere with or inhibit the cells. Understanding these developments requires detailed knowledge of how T cells recognize antigen, and of the receptors involved in autoimmune diseases. This article reviews the current literature on T cell receptor structure, and summarizes what is currently known about the usage of specific T cell receptors in autoimmune rheumatic disease.

    Rheumatic disease can loosely be described as any painful condition affecting the loco-motor system, including joints, muscles, connective tissues, and soft tissues around the joints and bones. There is a wide spectrum of rheumatic diseases, many of which involve autoimmunity, including systemic lupus erythematosus and rheumatoid arthritis. A significant body of evidence now links aberrant epigenetic regulation of gene expression with rheumatic disease and points toward the use of epigenetic targeting agents as potential new treatment options, particularly for those conditions associated with an autoimmune element. In this perspective, I will briefly cover the current knowledge surrounding this area in the field of rheumatology. PMID:23510070

    In the past few years, new developments have been reported on the role of Toll-like receptors (TLRs) in chronic inflammation in rheumatic diseases. The inhibitory function of TLR10 has been demonstrated. Receptors that enhance the function of TLRs, and several TLR inhibitors, have been identified. In addition, the role of the microbiome and TLRs in the onset of rheumatic diseases has been reported. We review novel insights on the role of TLRs in several inflammatory joint diseases, including rheumatoid arthritis, systemic lupus erythematosus, gout and Lyme arthritis, with a focus on the signalling mechanisms mediated by the Toll-IL-1 receptor (TIR) domain, the exogenous and endogenous ligands of TLRs, and the current and future therapeutic strategies to target TLR signalling in rheumatic diseases.

    Thymic stromal lymphopoietin (TSLP) is an IL-7-related cytokine that has been studied extensively in atopic diseases and more recently in various rheumatic disorders. It is involved in T cell development in the thymus and promotes homeostatic T cell expansion by classical dendritic cells. However, deregulated TSLP expression in various rheumatic diseases has implicated this cytokine as a strong mediator in immunopathology. Overexpressed TSLP induces strong T cell activation and production of pro-inflammatory cytokines in human cells and animal models for RA, SSc and LN, underscoring the therapeutic potential of targeting the TSLP-TSLP receptor axis.

    Background Cutaneous abnormalities are common in rheumatoid arthritis, but exact prevalence estimates are yet to be established. Some abnormalities may be independent and coincidental, whereas others may relate to rheumatoid arthritis or its treatment. Objectives To determine the exact nature and point prevalence of cutaneous abnormalities in patients with rheumatoid arthritis compared with those in patients with non‐inflammatory rheumatic disease. Methods 349 consecutive outpatients for rheumatology (205 with rheumatoid arthritis and 144 with non‐inflammatory rheumatic conditions) were examined for skin and nail signs by a dermatologist. Histories of rheumatology, dermatology, drugs and allergy were noted in detail. Results Skin abnormalities were reported by more patients with rheumatoid arthritis (61%) than non‐inflammatory controls (47%). More patients with rheumatoid arthritis (39%) than controls (10%) attributed their skin abnormality to drugs. Cutaneous abnormalities observed by the dermatologist were also more common in patients with rheumatoid arthritis (76%) than in the group with non‐inflammatory disease (60%). Specifically, bruising, athlete's foot, scars, rheumatoid nodules and vasculitic lesions were more common in patients with rheumatoid arthritis than in controls. The presence of bruising was predicted only by current steroid use. The presence of any other specific cutaneous abnormalities was not predicted by any of the variables assessed. In the whole group, current steroid use and having rheumatoid arthritis were the only important predictors of having any cutaneous abnormality. Conclusions Self‐reported and observed cutaneous abnormalities are more common in patients with rheumatoid arthritis than in controls with non‐inflammatory disease. These include cutaneous abnormalities related to side effects of drugs or to rheumatoid arthritis itself and other abnormalities previously believed to be independent but which may be of clinical

    There is evidence of early progress in the efforts to eliminate acute rheumatic fever (ARF) and control rheumatic heart disease (RHD) in South Africa. The caseload of ARF and RHD in paediatric units appears to be falling in some provinces such as Gauteng, and the mortality attributed to rheumatic heart disease at a population level has fallen from 1.3/100 000 in 2001 to 0.7/100 000 in 2012. However, the incidence of congestive heart failure due to RHD in adults remains high (~25/100 000/year) in Gauteng Province, and is associated with a high case fatality rate of up to 35% in 6 months. There is a need to intensify the application of comprehensive interventions to enhance the primary and secondary prevention and treatment of ARF/RHD in a registry-based national programme.

    Mind body therapies (MBT) share a global approach involving both mental and physical dimensions, and focus on relationship between brain, mind, body and behavior and their effects on health and disease. MBT include concentration based therapies and movement based therapies, comprising traditional Oriental practices and somatic techniques. The greatest part of rheumatic diseases have a chronic course, leading to progressive damages at musculoskeletal system and causing physical problems, psychological and social concerns. Thus, rheumatic patients need to be treated with a multidisciplinary approach integrating pharmacological therapies and rehabilitation techniques, that not should only aim to reduce the progression of damages at musculoskeletal system. Thus, MBT, using an overall approach, could be useful in taking care of the overall health of the patients with chronic rheumatic diseases. This review will deal with different MBT and with their effects in the most common chronic rheumatic diseases (Rheumatoid Arthritis, Ankylosing Spondylitis, Fibromyalgia Syndrome). PMID:26850811

    Autoreactive B cells are characterized by their ability to secrete autoantibodies directed against self-peptides. During the last decade, it has become increasingly apparent that B lymphocytes not only produce autoantibodies but also exert important regulatory roles independent of their function as antibody-producing cells. This is especially relevant in the context of autoimmunity, because autoreactive B cells have been shown to possess the ability to activate pathogenic T cells, to produce pro-inflammatory cytokines, and to promote the formation of tertiary lymphoid tissue in target organs. The production of monoclonal antibodies against B-cell-surface molecules has facilitated the characterization of several distinct B lymphocyte subsets. These cell-surface molecules have not only served as useful cell differentiation markers but have also helped to unravel the important biological functions of these cells. Some of these molecules, all of which are expressed on the cell surface, have proven to be effective therapeutic targets. In both animal models and in clinical assays, the efficient elimination of B lymphocytes has been shown to be useful in the treatment of rheumatoid arthritis and other autoimmune diseases. The treatment of most rheumatic autoimmune diseases relies mainly on the use of cytotoxic immunosuppressants and corticosteroids. Although this has resulted in improved disease survival, patients may nonetheless suffer severe adverse events and, in some cases, their relapse rate remains high. The increasing need for safer and more effective drugs along with burgeoning new insights into the pathogenesis of these disorders has fueled interest in biological agents; clinical trials involving the B-cell depletion agent rituximab have been especially promising. This article reviews the current knowledge of B-cell biology and pathogenesis as well as the modern therapeutic approaches for rheumatic autoimmune diseases focusing in particular on the targeting of B

    The proven effectiveness of biologics and other immunomodulatory products in inflammatory rheumatic diseases has resulted in their widespread use as well as reports of potential short- and long-term complications such as infection and malignancy. These complications are especially worrisome in children who often have serial exposures to multiple immunomodulatory products. Post-marketing surveillance of immunomodulatory products in juvenile idiopathic arthritis (JIA) and pediatric systemic lupus erythematosus is currently based on product-specific registries and passive surveillance, which may not accurately reflect the safety risks for children owing to low numbers, poor long-term retention, and inadequate comparators. In collaboration with the US Food and Drug Administration (FDA), patient and family advocacy groups, biopharmaceutical industry representatives and other stakeholders, the Childhood Arthritis and Rheumatology Research Alliance (CARRA) and the Duke Clinical Research Institute (DCRI) have developed a novel pharmacosurveillance model (CARRA Consolidated Safety Registry [CoRe]) based on a multicenter longitudinal pediatric rheumatic diseases registry with over 8000 participants. The existing CARRA infrastructure provides access to much larger numbers of subjects than is feasible in single-product registries. Enrollment regardless of medication exposure allows more accurate detection and evaluation of safety signals. Flexibility built into the model allows the addition of specific data elements and safety outcomes, and designation of appropriate disease comparator groups relevant to each product, fulfilling post-marketing requirements and commitments. The proposed model can be applied to other pediatric and adult diseases, potentially transforming the paradigm of pharmacosurveillance in response to the growing public mandate for rigorous post-marketing safety monitoring.

    The glucocorticoid receptor (GR), a member of the nuclear receptor superfamily, mediates most of the known biologic effects of glucocorticoids. The human GR gene consists of 9 exons and expresses 2 alternative splicing isoforms, the GRα and GRβ. GRα is the classic receptor that binds to glucocorticoids and mediates most of the known actions of glucocorticoids, while GRβ does not bind to these hormones and exerts a dominant negative effect upon the GRα-induced transcriptional activity. Each of the two GR splice isoforms has 8 translational variants with specific transcriptional activity and tissue distribution. GRα consists of three subdomains, translocates from the cytoplasm into the nucleus upon binding to glucocorticoids, and regulates the transcriptional activity of numerous glucocorticoid-responsive genes either by binding to its cognate DNA sequences or by interacting with other transcription factors. In addition to these genomic actions, the GR also exerts rapid, non-genomic effects, which are possibly mediated by membrane-localized receptors or by translocation into the mitochondria. All these actions of the GR appear to play an important role in the regulation of the immune system. Specifically, the splicing variant GRβ may be involved in the pathogenesis of rheumatic diseases, while the circadian regulation of the GR activity via acetylation by the Clock transcription factor may have therapeutic implications for the preferential timing of glucocorticoid administration in autoimmune inflammatory disorders.

    In the past years, ultrasound imaging has become an integral element of the diagnostic process in rheumatic diseases. It enables the identification of a range of inflammatory changes in joint cavities, sheaths and bursae, and allows their activity to be assessed. In 2012, experts of the European Society of Musculoskeletal Radiology prepared recommendations concerning the role of ultrasonography in the diagnosis of musculoskeletal diseases. Ultrasound was considered the method of choice in imaging peripheral synovitis. Moreover, ultrasound imaging has been popularized thanks to the new classification criteria for rheumatoid arthritis issued by the American College of Rheumatology and European League Against Rheumatism in 2010. They underline the role of ultrasound imaging in the detection of articular inflammatory changes that are difficult to assess unambiguously in the clinical examination. These criteria have become the basis for recommendations prepared by experts from the European League Against Rheumatism concerning medical imaging in rheumatoid arthritis. Nine of ten recommendations concern ultrasonography which is relevant in detecting diseases, predicting their progression and treatment response, monitoring disease activity and identifying remission. In the new criteria concerning polymyalgia rheumatica from 2012, an ultrasound scan of the shoulder and pelvic girdle was considered an alternative to clinical assessment. Moreover, the relevance of ultrasonography in the diagnosis and monitoring of peripheral spondyloarthropathies was widely discussed in 2014 during the meeting of the European League Against Rheumatism in Paris.

    Objective To evaluate the immunological profile and gene expression of endothelin-1 (ET-1) in mitral valves of patients with rheumatic fever originated from a reference service in cardiovascular surgery. Methods This was a quantitative, observational and cross-sectional study. Thirty-five subjects (divided into four groups) participated in the study, 25 patients with chronic rheumatic heart disease and ten control subjects. The mean age of the sample studied was 34.5 years. Seventeen of them (48.58%) were male and 18 (51.42%) were female. Inflammatory cytokines (TNF-α, IL-4 and IL-10) were measured and ten mitral valves of patients who underwent first valve replacement were collected for determination of gene expression of endothelin-1 by real time PCR. Results Among the groups studied (patients vs. controls), there was a statistically significant difference in IL-10 levels (P=0.002), and no differences in other cytokines. Expression of endothelin-1 was observed in 70% of samples. Quantitatively, average of ET-1 expression was 62.85±25.63%. Conclusion Inflammatory cytokine IL-10 participates in the maintenance of chronicity of rheumatic fever in patients who underwent valve replacement and those who are undergoing medical treatment. The expression of endothelin-1 in heart valve lesions in patients undergoing mitral valve replacement confirms its association with inflammatory activity in rheumatic fever. PMID:24896159

    The role of the potent proinflammatory cytokine IL-1 in disease could clinically be investigated with the development of the IL-1 blocking agent anakinra (Kineret®), a recombinant IL-1 receptor antagonist. It was first tested in patients with sepsis without much benefit but was later FDA approved for the treatment of patients with rheumatoid arthritis. More recently IL-1 blocking therapies are used successfully to treat a new group of immune-mediated inflammatory conditions, autoinflammatory diseases. These conditions include rare hereditary fever syndromes and pediatric and adult conditions of Still’s disease. Recently the FDA approved two additional longer acting IL-1 blocking agents, for the treatment of cryopyrin-associated periodic syndromes (CAPS), an IL-1 dependent autoinflammatory syndrome. The study of autoinflammatory diseases revealed mechanisms of IL-1 mediated organ damage and provided concepts to a better understanding of the pathogenesis of more common diseases such as gout and Type 2 diabetes which show initial promising results with IL-1 blocking therapy.

The decline of frequency of RF in these countries is largely due to improved medical services leading to wide use of antibiotics to treat bacterial pharyngitis. In many developing countries, the incidence is decreased due to development of integrated control programs. Depending on secondary prophylaxis alone was shown to be ineffective, therefore, many countries, including Sudan initiated control programs that utilize both primary and secondary prevention together with increasing awareness and surveillance.

    It is known that the prevalence of depression in rheumatologic patients is higher than in the general population. Socioeconomic factors are not a sufficient explanation of mood disorder in these patients. Symptoms reported by patients with chronic inflammatory diseases resemble changes defined as "sickness behavior". Mood disorders among somatic patients could be explained by disturbances of the immune system according to the monoaminergic theory of depression. Inflammatory factors such as IL-1 (interleukin-1), IL-2 (interleukin-2), IL-6 (interleukin-6), TNF-α (tumor necrosis factor α), and IFN-γ (interferon-γ) act within the CNS (central nervous system). They get through from peripheral tissues as well as being synthesized de novo by neurons. This cytokine activity correlates positively with depression intensity as well as with genetic polymorphism of the serotonin (5-HT) transporter. The theory of glucocorticoid resistance-mediated depression (limbic-hypothalamic-pituitary-adrenal [LHPA] axis) is also connected with gained proinflammatory cytokines activity. It might assume the form of a vicious circle. Depressed mood is probably linked with depression in immune-mediated diseases. An elevated level of proinflammatory cytokines is able to activate IDO (indoleamine 2,3-dioxygenase)--an enzyme catabolizing tryptophan (5-HT precursor). Those reactions probably play the main role at the biochemical level. IDO metabolites extensively disturb neurotransmission. 3-Hydroxykynurenine (3OH-KYN), quinolinic acid (Quin) and kynurenic acid (KYNA) are neurotoxic by releasing oxidative stress mediators. Moreover, they activate MAO (monoamine oxidase), which degrades neurotransmitters responsible for stable mood. Bidirectional communication between the neuroendocrine and immune systems is significant for depression treatment, as well as CNS protection against incremental neurodegeneration among seemingly diverse diseases.

    To examine time trends and differences in mortality rates from acute rheumatic fever and chronic rheumatic heart disease in New Mexico's Hispanic, American Indian, and non-Hispanic white populations, we analyzed vital records data for 1958 through 1982. Age-adjusted mortality rates for acute rheumatic fever were low and showed no consistent temporal trends among the three ethnic groups over the study period. Age-adjusted and age-specific mortality rates for chronic rheumatic heart disease in Hispanic and non-Hispanic whites decreased over the 25-year period, although rates were higher among Hispanics than among non-Hispanics during most of the time period. In American Indians, age-adjusted mortality rates for chronic rheumatic heart disease increased between 1968 and 1977 to twice the non-Indian mortality rates during the same period. Despite this increase in mortality from chronic rheumatic heart disease among New Mexico's American Indians from 1968 to 1977, the New Mexico data generally reflect national trends of decreasing mortality from chronic rheumatic heart disease.

    Naturally occurring Foxp3(+)CD25(+)CD4(+) regulatory T (TREG) cells maintain immunological self-tolerance and prevent a variety of autoimmune diseases, including rheumatic diseases such as rheumatoid arthritis and systemic lupus erythematosus. In animal models of rheumatic disease, autoimmune responses can be controlled by re-establishing the T-cell balance in favour of TREG cells. Here we discuss three potential strategies for the clinical use of TREG cells to treat autoimmune rheumatic disease: expansion of self-antigen-specific natural TREG cells in vivo; propagation of antigen-specific natural TREG cells ex vivo, by in vitro antigenic stimulation, and subsequent transfer back into the host; or conversion of antigen-specific conventional T cells into TREG cells in vivo or ex vivo. These strategies require depletion of the effector T cells that mediate autoimmunity before initiating TREG-cell-based therapies. Immunotherapies that target TREG cells, and the balance of TREG cells and autoreactive T cells, are therefore an important modality for the treatment of autoimmune rheumatic disease. PMID:24980140

    P-glycoprotein (Pgp) is a transmembrane protein of 170 kD encoded by the multidrug resistance 1 (MDR-1) gene, localized on chromosome 7. More than 50 polymorphisms of the MDR-1 gene have been described; a subset of these has been shown to play a pathophysiological role in the development of inflammatory bowel disease, femoral head osteonecrosis induced by steroids, lung cancer and renal epithelial tumors. Polymorphisms that have a protective effect on the development of conditions such as Parkinson disease have also been identified. P-glycoprotein belongs to the adenosine triphosphate binding cassette transporter superfamily and its structure comprises a chain of approximately 1280 aminoacid residues with an N-C terminal structure, arranged as 2 homologous halves, each of which has 6 transmembrane segments, with a total of 12 segments with 2 cytoplasmic nucleotide binding domains. Many cytokines like interleukin 2 and tumor necrosis factor alpha increase Pgp expression and activity. Pgp functions as an efflux pump for a variety of toxins in order to protect particular organs and tissues as the central nervous system. Pgp transports a variety of substrates including glucocorticoids while other drugs such as tacrolimus and cyclosporine A act as modulators of this protein. The most widely used method to measure Pgp activity is flow cytometry using naturally fluorescent substrates such as anthracyclines or rhodamine 123. The study of drug resistance and its association to Pgp began with the study of resistance to chemotherapy in the treatment of cancer and antiretroviral therapy for human immunodeficiency virus; however, the role of Pgp in the treatment of systemic lupus erythematosus, rheumatoid arthritis and psoriatic arthritis has been a focus of study lately and has emerged as an important mechanism by which treatment failure occurs. The present review analyzes the role of Pgp in these autoimmune diseases. PMID:25712147

    The alterations in glycosylation of serum glycoproteins were reported in several pathological conditions including rheumatic diseases. The many studies demonstrated the occurrence of some differentially glycosylated plasma immunoglobulins, especially IgG in rheumatoid arthritis. The most characteristic features are the decrease in galactose content, the presence of N-acetylglucosamine and the increase in fucose content. The structure of oligosaccharides attached to the antibody Fc region affect the pharmacokinetics and antibody effector functions of antibody-dependent cellular cytotoxicity and complement-dependent cytotoxicity. The changes in immunoglobulin glycosylation was suggested to be important in the etiology of rheumatoid athritis and correlated with the disease severity. In addition to impaired glycosylation of imunoglubulins, in rheumatic diseases exist the disturbances in glycosylation of both acute-phase and non acute-phase response, such as alpha-1 acid glycoprotein, haptoglobin and alpha-2 macroglobulin.

    The role of the gut microbiome in animal models of inflammatory and autoimmune disease is now well established. The human gut microbiome is currently being studied as a potential modulator of the immune response in rheumatic disorders. However, the vastness and complexity of this host-microorganism interaction is likely to go well beyond taxonomic, correlative observations. In fact, most advances in the field relate to the functional and metabolic capabilities of these microorganisms and their influence on mucosal immunity and systemic inflammation. An intricate relationship between the microbiome and the diet of the host is now fully recognized, with the microbiota having an important role in the degradation of polysaccharides into active metabolites. This Review summarizes the current knowledge on the metabolic role of the microbiota in health and rheumatic disease, including the advances in pharmacomicrobiomics and its potential use in diagnostics, therapeutics and personalized medicine.

    2016-07-01

    Various subtypes of effector T cells have been described up to date, and each one has its specific immunological function and a defined cytokine secretion profile. Th9 lymphocytes, recently described, are characterized by a high IL-9 expression. Their differentiation requires the integration of IL-4 and TGF-β signaling pathways and the coordinated participation of multiple transcription factors. Their role has been mainly found in immunity against parasites and in allergic inflammatory processes. Nevertheless, they have been implicated in processes as autoimmunity, cancer and recently in rheumatic diseases. The objective of this review is to describe the discovery of this cellular subtype, its differentiation, expression regulation and its potential role in rheumatic diseases. PMID:26921642

  16. Role of Helicobacter pylori infection in autoimmune systemic rheumatic diseases.

    The relationship between infection and autoimmunity has been increasingly defined over the last 20 years. The systemic rheumatic diseases are characterized by dysregulation of the immune system resulting in a loss of tolerance to self-antigen. The exact etiology for the majority of these diseases is unknown; however, a complex combination of host and environmental factors are believed to play a pivotal role. Helicobacter pylori (H. pylori) is one of the most widely studied infectious agents proposed as agents triggering autoimmune response. The persistent presence of H. pylori in the gastric mucosa results in chronic immune system activation with ongoing cytokine signaling, infiltration of gastric mucosa by neutrophils, macrophages, lymphocytes, as well as production of antibodies and effector T-cells. Various mechanisms have been proposed in an attempt to explain the extra-intestinal manifestations of H. pylori infections. These include: molecular mimicry, endothelial cell damage, superantigens and microchimerism. I performed a systematic literature review using the keywords "rheumatoid arthritis", "Sjögren's syndrome", "systemic sclerosis", "systemic lupus erythematosus", "Helicobacter pylori" and "pathogenesis". A systematic literature search was carried out in MEDLINE; EMBASE; Cochrane Library and ACR/EULAR meeting abstracts. In systemic rheumatic diseases H. pylori infection prevalence alone should not be expected to provide sufficient evidence for or against a pathologic role in the disease. In this article I review studies examining the potential involvement of H. pylori infection in autoimmune systemic rheumatic diseases. Further studies of the immunological response to H. pylori and its role in the pathogenesis of systemic rheumatic diseases are warranted. PMID:25278681

    Impairments of the immune system play an important role in all immun-mediated rheumatic diseases. Recently, the following news were reported: · Early aging of the immune system with thymus insufficiency has now been reported for both patients with rheumatoid arthritis and axial spondyloarthritis, without prethymic lack of progenitors at least in rheumatoid arthritis.. · For giant cell arteritis, the most frequent vasculitis in the elderly, an increased expression of IL-17A in temporal artery biopsies coincides with good prognosis and reponse to glucocorticoids.. · Concerning immunosenescence in systemic lupus erythematosus, BAFF appears to have an important role for relapses after B-cell depletion.. For the future it can be anticipated that the use of unified classification criteria for rheumatic diseases (as with the new 2012 EULAR / ACR classification criteria for polymyalgia rheumatica) will ensure better comparability of immunological studies also in the elderly.

    In order to determine whether adequate attention is paid to the maintenance of good oral health in patients at risk of developing infective endocarditis, we studied 44 black patients with severe rheumatic heart disease before they had cardiac surgery. Plaque and gingival index scores were calculated and panoramic radiographs were done in all patients. There were 17 males and 27 females (mean age: 30.6 years). The plaque and gingival index scores were classified as poor in 31.8 and 54.6% of patients, respectively. Panoramic radiographic findings included caries in 56.8% of patients, peri-apical pathology in 18.1% and retained roots in 22.7% of patients. This study demonstrates that inadequate attention is paid to the maintenance of good oral health in patients with severe rheumatic heart disease. The oral and dental care of patients at risk of developing infective endocarditis needs to be improved. PMID:22836156

    Ankylosing spondylitis (AS) is an inflammatory disorder affecting the axial skeleton, peripheral joints, entheses and extra-articular sites. Patients with early disease, a higher level of erythrocyte sedimentation rate and/or peripheral arthritis might benefit from sulfasalazine. Otherwise, there is no evidence that disease-modifying anti-rheumatic (DMARDs) have a therapeutic effect in AS. Clinical evidence that greater TNF-inhibitor effectiveness can be achieved by combining with a DMARD is lacking, but further studies should be performed. More research is needed to clarify the role of DMARDs in the treatment of AS. PMID:19732504

    ABSTRACT Background Improved targeted therapies for rheumatic diseases were developed recently resulting in a better prognosis for affected patients. Nowadays, patients are living longer and with improved quality of life, including fertility potential. These patients are affected by impaired reproductive function and the causes are often multifactorial related to particularities of each disease. This review highlights how rheumatic diseases and their management affect testicular function and male fertility. Materials and Methods A systematic review of literature of all published data after 1970 was conducted. Data was collected about fertility abnormalities in male patients with systemic lupus erythematosus, rheumatoid arthritis, dermatomyositis, ankylosing spondylitis, Behçet disease and gout. Two independent researchers carried out the search in online databases. Results A total of 19 articles were included addressing the following diseases: 7 systemic lupus erythematosus, 6 Behçet disease, 4 ankylosing spondylitis, 2 rheumatoid arthritis, 2 dermatomyositis and one gout. Systemic lupus erythematosus clearly affects gonadal function impairing spermatogenesis mainly due to antisperm antibodies and cyclophosphamide therapy. Behçet disease, gout and ankylosing spondylitis patients, including those under anti-TNF therapy in the latter disease, do not seem to have reduced fertility whereas in dermatomyositis, the fertility potential is hampered by disease activity and by alkylating agents. Data regarding rheumatoid arthritis is scarce, gonadal dysfunction observed as consequence of disease activity and antisperm antibodies. Conclusions Reduced fertility potential is not uncommon. Its frequency and severity vary among the different rheumatic diseases. Permanent infertility is rare and often associated with alkylating agent therapy. PMID:27120778

    Our objective was to evaluate the prevalence of autoantibodies to cyclic citrullinated peptides (anti-CCP aAbs) in a cohort of patients with a variety of inflammatory or non-inflammatory rheumatic diseases other than rheumatoid arthritis (RA). Six hundred and nine serum samples were tested for anti-CCP aAbs and for rheumatoid factor (RF) using enzyme-linked immunosorbent assays and immunonephelometry. The prevalence of anti-CCP aAbs and RF reached 10% and 25%, respectively, using the positive cutoff value suggested by the manufacturers. Using a higher cutoff value (50 U/ml) for both aAbs, the prevalence was lower with 6% and 16%, respectively. The specificity of both markers for RA thus reached 94% and 84%, respectively. Anti-CCP aAbs were found to be elevated in inflammatory and also in non-inflammatory rheumatic diseases in the same proportion. Clinical data obtained for 36 positive patients showed that 17% developed RA within 5 years. In conclusion, anti-CCP aAbs are clearly more specific than RF for RA. Follow-up of anti-CCP aAbs-positive patients with inflammatory or non-inflammatory rheumatic diseases other than RA could be important considering the predictive value of these aAbs for the development of RA.

    In the field of rheumatology, conventional diagnostic methods permit the detection only of advanced stages of the disease, which is at odds with the current clinical demand for the early diagnosis of inflammatory rheumatic diseases. Prompted by current needs, we developed a finger joint phantom that enables the optical and geometrical simulation of an early stage of rheumatoid arthritis (RA). The results presented here form the experimental basis for an evaluation of new RA diagnostic systems based on near infrared light. The early stage of RA is characterised mainly by a vigorous proliferation of the synovial membrane and clouding of the synovial fluid. Using a double-integrating-sphere technique, the absorption and scattering coefficients (mua, mus') are experimentally determined for healthy and pathologically altered synovial fluid and capsule tissue. Using a variable mixture of Intralipid Indian ink and water as a scattering/absorption medium, the optical properties of skin, synovial fluid or capsule can be selected individually. Since the optical and geometrical properties of bone tissue remain constant in early-stage RA, a solid material is used for its simulation. Using the finger joint phantom described herein, the optical properties of joint regions can be adjusted specifically, enabling an evaluation of their effects on an optical signal--for example, during fluorography--and the investigation of these effects for diagnostically useful information. The experimental foundation for the development of a new optical system for the early diagnosis of RA has now been laid. PMID:9490122

    Retinoid, a derivative of vitamin A, is a general term used to describe compounds that bind to and activate retinoic acid receptors [RARs (RARα, RARβ, and RARγ)] and/or retinoid X receptors [RXRs (RXRα, RXRβ, and RXRγ)]. They have been shown to surpress the differentiation of Th1/Th17 cells and induce the development of Th1/regulatory T cells. They also affect the proliferation of B cells as both an inducer and suppressor. Furthermore, retinoids may induce the maturation of dendritic cells and production of interleukin-10 from monocytes/macrophages. We recently demonstrated that retinoids suppressed the production of reactive oxygen species, the release of elastase from neutrophils by inhibiting mitogen-activated protein kinase signals, and both the migration speed and chemotaxis directionality of neutrophils. Retinoids, such as all-trans retinoic acid and tamibarotene, were previously shown to have positive effects on animal models of several rheumatic diseases, including arthritis, myositis, and vasculitis in vivo. Moreover, retinoids have been used in a pilot study to effectively treat patients with lupus nephritis and systemic sclerosis. We herein reviewed the effects of retinoids on immune cells, animal models of rheumatic diseases, and rheumatic patients. PMID:24939557

    Fms-like tyrosine kinase 3 (Flt-3) is a cytokine receptor expressed on the surface of bone-marrow progenitor of hematopoietic cells. Flt-3 ligands are produced by peripheral blood mononuclear cells, and found in various human body fluids. Flt-3 signal is involved in the regulation of vessel formation as well as B cell differentiation, suggesting that Flt-3 signal contributes to the pathogenesis of vascular abnormalities and immune dysregulation in rheumatic diseases. The aim of the present study is to examine serum Flt-3 ligand levels in patients with various rheumatic diseases, and to evaluate the possibility that serum Flt-3 ligand levels can be a useful disease marker. Sera were obtained from 20 dermatomyositis (DM) patients, 36 systemic sclerosis (SSc) patients, 10 systemic lupus erythematosus (SLE) patients, 10 scleroderma spectrum disorder (SSD) patients, 4 mixed connective tissue disease (MCTD) patients, and 12 normal subjects. Flt-3 ligand levels were determined with ELISA. Serum Flt-3 ligand levels were significantly elevated in patients with DM, SSc, SSD and MCTD compared to those in normal subjects. DM patients with elevated Flt-3 ligand levels were accompanied with significantly increased CRP levels and increased frequency of heliotrope rash than those with normal levels. In addition, SSc patients with elevated Flt-3 ligand levels showed significantly reduced frequency of nailfold bleeding. Serum Flt-3 ligand levels can be a marker of cutaneous manifestation in DM and a marker of microangiopathy in SSc. Clarifying the role of Flt-3 ligand in rheumatic diseases may lead to further understanding of these diseases and new therapeutic approaches. PMID:26559027

  5. Managing pregnancy in inflammatory rheumatological diseases

    PubMed Central

    2011-01-01

    Historically, pregnancy in women with many inflammatory rheumatic diseases was not considered safe and was discouraged. Combined care allows these pregnancies to be managed optimally, with the majority of outcomes being favorable. Disease activity at the time of conception and anti-phospholipid antibodies are responsible for most complications. Disease flares, pre-eclampsia, and thrombosis are the main maternal complications, whereas fetal loss and intrauterine growth restriction are the main fetal complications. Antirheumatic drugs used during pregnancy and lactation to control disease activity are corticosteroids, hydroxychloroquine, sulphasalzine, and azathioprine. Vaginal delivery is possible in most circumstances, with cesarean section being reserved for complications. PMID:21371350

    Background: We investigated adverse outcomes for people with acute rheumatic fever (ARF) and rheumatic heart disease (RHD) and the effect of comorbidities and demographic factors on these outcomes. Methods: Using linked data (RHD register, hospital, and mortality data) for residents of the Northern Territory of Australia, we calculated ARF recurrence rates, rates of progression from ARF to RHD to severe RHD, RHD complication rates (heart failure, endocarditis, stroke, and atrial fibrillation), and mortality rates for 572 individuals diagnosed with ARF and 1248 with RHD in 1997 to 2013 (94.9% Indigenous). Results: ARF recurrence was highest (incidence, 3.7 per 100 person-years) in the first year after the initial ARF episode, but low-level risk persisted for >10 years. Progression to RHD was also highest (incidence, 35.9) in the first year, almost 10 times higher than ARF recurrence. The median age at RHD diagnosis in Indigenous people was young, especially among males (17 years). The development of complications was highest in the first year after RHD diagnosis: heart failure incidence rate per 100 person-years, 9.09; atrial fibrillation, 4.70; endocarditis, 1.00; and stroke, 0.58. Mortality was higher among Indigenous than non-Indigenous RHD patients (hazard ratio, 6.55; 95% confidence interval, 2.45–17.51), of which 28% was explained by comorbid renal failure and hazardous alcohol use. RHD complications and mortality rates were higher for urban than for remote residents. Conclusions: This study provides important new prognostic information for ARF/RHD. The residual Indigenous survival disparity in RHD patients, which persisted after accounting for comorbidities, suggests that other factors contribute to mortality, warranting further research.

    Rheumatic heart disease (RHD) is a chronic valvular disease resulting after severe or repetitive episodes of acute rheumatic fever (ARF), an autoimmune response to group A Streptococcus infection. RHD has been almost eliminated with improved social and health infrastructure in affluent countries while it remains a neglected disease with major cause of morbidity and mortality in many low- and middle-income countries, and resource-limited regions of high-income countries. Despite our evolving understanding of the pathogenesis of RHD, there have not been any significant advances to prevent or halt progression of disease in recent history. Long-term penicillin-based treatment and surgery remain the backbone of a RHD control program in the absence of an effective vaccine. The advent of echocardiographic screening algorithms has improved the accuracy of diagnosing RHD and has shed light on the enormous burden of disease. Encouragingly, this has led to a rekindled commitment from researchers in the most affected countries to advocate and take bold actions to end this disease of social inequality. PMID:27566329

    Abstract Patients with rheumatic diseases can present with movement and other neurodegenerative disorders. It may be underappreciated that movement and other neurodegenerative disorders can encompass a wide variety of disease entities. Such disorders are strikingly heterogeneous and lead to a wider spectrum of clinical injury than seen in Parkinson's disease. Therefore, we sought to stringently phenotype movement and other neurodegenerative disorders presenting in a case series of rheumatic disease patients. We integrated our findings with a review of the literature to understand mechanisms which may account for such a ubiquitous pattern of clinical injury. Seven rheumatic disease patients (5 Sjögren's syndrome patients, 2 undifferentiated connective tissue disease patients) were referred and could be misdiagnosed as having Parkinson's disease. However, all of these patients were ultimately diagnosed as having other movement or neurodegenerative disorders. Findings inconsistent with and more expansive than Parkinson's disease included cerebellar degeneration, dystonia with an alien-limb phenomenon, and nonfluent aphasias. A notable finding was that individual patients could be affected by cooccurring movement and other neurodegenerative disorders, each of which could be exceptionally rare (ie, prevalence of ∼1:1000), and therefore with the collective probability that such disorders were merely coincidental and causally unrelated being as low as ∼1-per-billion. Whereas our review of the literature revealed that ubiquitous patterns of clinical injury were frequently associated with magnetic resonance imaging (MRI) findings suggestive of a widespread vasculopathy, our patients did not have such neuroimaging findings. Instead, our patients could have syndromes which phenotypically resembled paraneoplastic and other inflammatory disorders which are known to be associated with antineuronal antibodies. We similarly identified immune-mediated and inflammatory markers

  9. Cartilage homeostasis in health and rheumatic diseases

    2009-01-01

    As the cellular component of articular cartilage, chondrocytes are responsible for maintaining in a low-turnover state the unique composition and organization of the matrix that was determined during embryonic and postnatal development. In joint diseases, cartilage homeostasis is disrupted by mechanisms that are driven by combinations of biological mediators that vary according to the disease process, including contributions from other joint tissues. In osteoarthritis (OA), biomechanical stimuli predominate with up-regulation of both catabolic and anabolic cytokines and recapitulation of developmental phenotypes, whereas in rheumatoid arthritis (RA), inflammation and catabolism drive cartilage loss. In vitro studies in chondrocytes have elucidated signaling pathways and transcription factors that orchestrate specific functions that promote cartilage damage in both OA and RA. Thus, understanding how the adult articular chondrocyte functions within its unique environment will aid in the development of rational strategies to protect cartilage from damage resulting from joint disease. This review will cover current knowledge about the specific cellular and biochemical mechanisms that regulate cartilage homeostasis and pathology. PMID:19519926

    There is growing interest in developing tools and methods for the surveillance of chronic rheumatic diseases, using existing resources such as administrative health databases. To illustrate how this might work, we used population-based administrative data to estimate and compare the prevalence of systemic autoimmune rheumatic diseases (SARDs) across three Canadian provinces, assessing for regional differences and the effects of demographic factors. Cases of SARDs (systemic lupus erythematosus, scleroderma, primary Sjogren's, polymyositis/dermatomyositis) were ascertained from provincial physician billing and hospitalization data. We combined information from three case definitions, using hierarchical Bayesian latent class regression models that account for the imperfect nature of each case definition. Using methods that account for the imperfect nature of both billing and hospitalization databases, we estimated the over-all prevalence of SARDs to be approximately 2-3 cases per 1,000 residents. Stratified prevalence estimates suggested similar demographic trends across provinces (i.e. greater prevalence in females-versus-males, and in persons of older age). The prevalence in older females approached or exceeded 1 in 100, which may reflect the high burden of primary Sjogren's syndrome in this group. Adjusting for demographics, there was a greater prevalence in urban-versus-rural settings. In our work, prevalence estimates had good face validity and provided useful information about potential regional and demographic variations. Our results suggest that surveillance of some rheumatic diseases using administrative data may indeed be feasible. Our work highlights the usefulness of using multiple data sources, adjusting for the error in each. PMID:20665025

    STUDY OBJECTIVE--The aim was to assess patients willingness to accept mortal risk in the drug treatment of chronic rheumatic disease. DESIGN--A non-random sample of consecutive patients were interviewed with a standardised survey instrument. SETTING--The study took place in the Royal National Hospital for Rheumatic Diseases, Bath, UK. PATIENTS--100 consecutive in- and out-patients aged 65 or less were interviewed, 50 with rheumatoid arthritis and 50 with ankylosing spondylitis. Mean age was 48 years with mean disease duration of 14 years. The rheumatoid arthritis group was mainly female (84%), v 26% in the ankylosing spondylitis group. MEASUREMENTS AND MAIN RESULTS--Risk preferences were elicited using the method of standard gamble in the context of a hypothetical new drug. Patients indicated the maximum percentage probability of mortality they regarded as acceptable to achieve four different levels of benefit: total cure (20.7%), relief of pain (16.9%), relief of stiffness (13.1%), return to normal functioning (14.5%). Rheumatoid arthritis patients displayed a higher (p less than 0.05) willingness to accept risk than ankylosing spondylitis patients for all gambles except relief of stiffness. Analysis of variance indicated that willingness to accept risk decreases with the duration of disease and increases with reductions in self assessed health status. CONCLUSIONS--Evaluative methods such as standard gamble can elicit useful risk-benefit preference data from patients to assist those who manage clinical risks. PMID:2273365

    OBJECTIVES--To redefine and comment on terms on a pathological basis, in order to avoid the confusion due to the use of terms with different meanings, to standardise usage among clinicians, radiologists and pathologists, and to facilitate literature searches. METHODS--Within the Committee of Pathology of the European League against Rheumatism, a study group was set up to analyse the medical literature and common practice concerning the nomenclature of rheumatic spinal diseases. The group tried to amalgamate the main trends in the field, to reconcile etymology, historical background, morphology, and common practice. RESULTS--The group warns against use of the terms 'acquired hyperostosis syndrome', '(von) Bechterew's disease', 'Kümmel's disease', 'pseudospondylolisthesis', 'rheumatoid spondylitis', 'spondylarthropathy' in the sense of spondarthritis, and 'spondylosis'. It recommends intercorporal or interapophyseal rather than intervertebral (osteo) chondrosis, zygapophyseal diverticulum rather than cyst, disc hernia rather than prolapse, spondyloarthritis rather than spondyloarthropathy, marginal rather than anterior spondylitis, and discarthrosis. It proposes 'zygarthrosis' to designate zygapophyseal osteoarthrosis. CONCLUSIONS--Knowledge of the pathological basis of diseases and an understanding of the original definitions given by those who coined new terms make it possible to avoid most of the confusion arising from improper use of spinal terms.

    This study aimed to estimate the prevalence of musculoskeletal disorders and rheumatic diseases among the indigenous Qom (Toba) population in the city of Rosario, Santa Fe, Argentina. An analytical cross-sectional study using methodology of the Community Oriented Program for the Control of Rheumatic Diseases (COPCORD) was performed. Subjects ≥18 years of age were interviewed by advanced students of medicine and nursing, bilingual translator-facilitators, and coordinators. Individuals with musculoskeletal pain (positive cases) were evaluated sequentially for 7 days by internists and rheumatologists for diagnosis and treatment. The study included 1656 individuals (77 % of the census population). Of these, 1020 (61.5 %) were female, with mean age of 35.3 (SD 13.9) years, and 1028 (62.0 %) were bilingual. The public health care system covers 87.1 % of the population. Musculoskeletal pain in the previous 7 days and/or at some time during their life was present in 890 subjects (53.7 %). Of those with pain in the last 7 days, 302 (64.1 %) subjects had an Health Assessment Questionnaire Disability Index (HAQ-DI) score ≥0.8. The most frequent pain sites were lumbar spine (19.3 %), knees (13.0 %), and hands (12.0 %). The prevalence of rheumatic diseases was as follows: mechanical back pain (20.1 %), rheumatic regional pain syndrome (2.9 %), osteoarthritis (4.0 %) rheumatoid arthritis (2.4 %), inflammatory back pain (0.2 %), systemic sclerosis (0.1 %), Sjögren syndrome (0.1 %), fibromyalgia (0.1 %), mixed connective tissue disease (0.06 %), and systemic lupus erythematosus (0.06 %). The prevalence of musculoskeletal disorders was 53.7 % and rheumatic diseases 29.6 %. Rheumatoid arthritis prevalence was 2.4 % using COPCORD methodology, one of the highest reported at present.

    Several inflammatory diseases have been associated with increased bone resorption and fracture rates and different studies supported the relation between inflammatory cytokines and osteoclast activity. The main factor required for osteoclast activation is the stimulation by receptor activator of nuclear factor kappa-B ligand (RANKL) expressed on osteoblasts. In this context, interleukin- (IL-) 1β, one of the most powerful proinflammatory cytokines, is a strong stimulator of in vitro and in vivo bone resorption via upregulation of RANKL that stimulates the osteoclastogenesis. The resulting effects lead to an imbalance in bone metabolism favouring bone resorption and osteoporosis. In this paper, we review the available literature on the role of IL-1β in the pathogenesis of bone loss. Furthermore, we analysed the role of IL-1β in bone resorption during rheumatic diseases and, when available, we reported the efficacy of anti-IL-1β therapy in this field. PMID:25954061

    Rheumatic heart disease is preventable but causes significant morbidity and mortality in Aboriginal Australian and Torres Strait Islander populations. Screening echocardiography has the potential to detect early rheumatic heart disease thereby enabling timely commencement of treatment (secondary prophylaxis) to halt disease progression. However, a number of issues prevent echocardiographic screening for rheumatic heart disease satisfying the Australian criteria for acceptable screening programs. Primarily, it is unclear what criteria should be used to define a positive screening result as questions remain regarding the significance, natural history and potential treatment of early and subclinical rheumatic heart disease. Furthermore, at present the delivery of secondary prophylaxis in Australia remains suboptimal such that the potential benefits of screening would be limited. Finally, the impact of echocardiographic screening for rheumatic heart disease on local health services and the psychosocial health of patients and families are yet to be ascertained. PMID:23638751

    The complex interaction of molecules within a biological system constitutes a functional module. These modules are then acted upon by both internal and external factors, such as genetic and environmental stresses, which under certain conditions can manifest as complex disease phenotypes. Recent advances in high-throughput biological analyses, in combination with improved computational methods for data enrichment, functional annotation, and network visualization, have enabled a much deeper understanding of the mechanisms underlying important biological processes by identifying functional modules that are temporally and spatially perturbed in the context of disease development. Systems biology approaches such as these have produced compelling observations that would be impossible to replicate using classical methodologies, with greater insights expected as both the technology and methods improve in the coming years. Here, we examine the use of systems biology and network analysis in the study of a wide range of rheumatic diseases to better understand the underlying molecular and clinical features. PMID:25750554

    Rheumatic fever (RF) and rheumatic heart disease RHD remain as one of the major cardiovascular problems in Sudanese children. The cornerstones for control of RF and RHD are primary and secondary preventions as adopted by Sudan’s programme. This study aimed to describe and raise the paediatric doctors’ awareness about prevention of RF and RHD using lectures. It was a prospective, cross-sectional, hospital based study, conducted in Khartoum. The study populations were paediatric doctors including house officers, medical officers and registrars. Data were collected through self-administered questionnaire, which was constructed to assess the doctor’s awareness about RF and RHD prevention before and after attending lectures. Eighty seven doctors participated in the study. The results showed that the overall doctors’ awareness about prevention of rheumatic fever and rheumatic heart disease was at average level. It was raised by intervention through lectures to good level. It is recommended to introduce training programs for physicians in order to improve doctors’ awareness about prevention of RF and RHD. Such activities need to be conducted at regular intervals.

  20. The value of glucocorticoid co-therapy in different rheumatic diseases - positive and adverse effects

    PubMed Central

    2014-01-01

    Glucocorticoids play a pivotal role in the management of many inflammatory rheumatic diseases. The therapeutic effects range from pain relief in arthritides, to disease-modifying effects in early rheumatoid arthritis, and to strong immunosuppressive actions in vasculitides and systemic lupus erythematosus. There are multiple indications that adverse effects are more frequent with the longer use of glucocorticoids and use of higher dosages, but high-quality data on the occurrence of adverse effects are scarce especially for dosages above 10 mg prednisone daily. The underlying rheumatic disease, disease activity, risk factors and individual responsiveness of the patient should guide treatment decisions. Monitoring for adverse effects should also be tailored to the patient. Continuously balancing the benefits and risks of glucocorticoid therapy is recommended. There is an ongoing quest for new drugs with glucocorticoid actions without the potential to cause harmful effects, such as selective glucocorticoid receptor agonists, but the application of a new compound in clinical practice will probably not occur within the next few years. In the meantime, basic research on glucocorticoid effects and detailed reports on therapeutic efficacy and occurrence of adverse effects will be valuable in weighing benefits and risks in clinical practice.

    The synovial membrane is frequently a target in rheumatic diseases. A search for diagnostic criteria and determination of changes in the pathological process necessitate standardized biopsy diagnostic techniques and quantification of morphological changes using digital imaging methods. The paper considers main methods for obtaining synovial membrane samples. It presents major morphological and immunohistochemical variations in synovitis in the presence of rheumatoid arthritis, ankylosing spondylitis, and osteoarthrosis. It shows different immunological and autoinflammatory mechanisms of these diseases. Synovial membrane inflammation in rheumatoid arthritis, ankylosing spondylitis, and osteoarthrosis is characterized by different components of morphogenesis, which is proven by the expression of different cell markers. Rheumatoid synovitis is an autoinflammatory process; synovitis in ankylosing spondylitis is characterized by autoinflammatory processes; biomechanical factors as joint inflammation triggers are leading in osteoarthrosis.

    Rheumatic heart disease (RHD) is a major public health problem in Nepal that affects young children and adolescents. Historically, many young people suffered severe valvular disease and died awaiting heart valve replacement. For some years, the Nepal Heart Foundation (NHF) advocated for a more comprehensive program to reduce the burden of RHD. In 2007, the government of Nepal announced funding for an RHD control program to be implemented by the NHF. The core focus of the program was to deliver antibiotics for the secondary prophylaxis of RHD. The NHF has developed a program of community awareness, free medication, RHD register development, health worker training, guideline development, and clinical audit. These services are being implemented with expanding geographic scope. This paper provides a narrative overview of the Nepalese experience designing, implementing, and beginning to evaluate this program. Challenges and successes relevant to register-based programs are highlighted. PMID:25690503

  4. MicroRNAs as biomarkers in rheumatic diseases

    2011-01-01

    Summary MicroRNAs (miRNAs) are endogenous, noncoding, single-stranded RNAs of 19–25 nucleotides in length. They regulate gene expression and are important in a wide range of physiological and pathological processes. MiRNAs are attractive as potential biomarkers because their expression pattern is reflective of the underlying pathophysiologic processes and they are specific to various disease states. Moreover, miRNAs can be detected in a variety of sources, including tissue, blood and body fluids; they are reasonably stable and appear to be resistant to differences in sample handling, which increases their appeal as practical biomarkers. The clinical utility of miRNAs as diagnostic or prognostic biomarkers has been demonstrated in various malignancies and a few nonmalignant diseases. There is accumulating evidence that miRNAs have an important role in systemic rheumatic diseases and that various diseases or different stages of the same disease are associated with distinct miRNA expression profiles. Preliminary data suggest that miRNAs are promising as candidate biomarkers of diagnosis, prognosis, disease activity and severity in autoimmune diseases. MiRNAs identified as potential biomarkers in pilot studies should be validated in larger studies specifically designed for biomarker validation. PMID:20517293

    The clinical management of autoimmune rheumatic diseases (ARD) has undergone significant changes in the last few decades, leading to remarkable improvements in clinical outcomes of many patients with mild to moderate ARD. On the other hand, severe refractory ARD patients often have high morbidity and mortality. Extensive basic research and clinical evidence has opened the door to new encouraging perspectives, such as the establishment of a role of stem cell transplantation (SCT) in the strategic management of ARD. Given the great heterogeneity of ARD, it is difficult to assign an optimal SCT regimen to all ARD patients. SCT remains a challenging mode of therapy in ARD patients from the standpoints of both efficacy and safety. As the clinical data of SCT in ARD increases and as we improve our understanding of stem cell biology and the downstream effects on the immune system, the future is promising for the development of optimal personalized SCT regimens in ARD.

    Acute dyspnea with pulmonary oedema in postpartum is uncommon but life-threatening event. Contributing factors for pulmonary oedema include, administration of tocolytics, underlying cardiac disease, iatrogenic fluid overload and preeclampsia acounting 0.08% of pregnancies. Pulmonary embolism, amniotic fluid embolism, pneumonia, aspiration and pulmonary oedema are some of the potentially devastating conditions that should be considered by the attending physician. Here, we report a case of postpartum acute pulmonary oedema referred to causality after an emergency caesarean section in a private hospital. No matter what the underlying pathology, prompt administration and appropriate resuscitation is always the first priority. Only after the patient has been stabilized attention must be turned to diagnosis and specific treatment. A diagnosis of severe Mitral Stenosis, probably of rheumatic origin was made after stabilizing the patient. PMID:25859501

    Screening for rheumatic heart disease (RHD) requires workers skilled in echocardiography, which typically involves prolonged, specialized training. Task shifting echocardiographic screening to nonexpert health workers may be a solution in settings with limited human resources. An 8-week training program was designed to train health workers without any prior experience in focused echocardiography for RHD screening. Seven health workers participated. At the completion of training, the health workers performed unsupervised echocardiography on 16 volunteer children with known RHD status. A pediatric cardiologist assessed image quality. Participants provided qualitative feedback. The quality of echocardiograms were high at completion of training (55 of 56 were adequate for diagnosis) and all cases of RHD were identified. Feedback was strongly positive. Training health workers to perform focused echocardiography for RHD screening is feasible. After systematic testing for accuracy, this training program could be adapted in other settings seeking to expand echocardiographic capabilities. PMID:26085762

    2013-01-01

    Curcumin (diferuloylmethane), a yellow coloring agent extracted from turmeric is also used as a remedy for the treatment and prevention of inflammatory diseases. Acute and chronic inflammation is a major factor in the progression of obesity, type II diabetes, arthritis, pancreatitis, cardiovascular, neurodegenerative and metabolic diseases, as well as certain types of cancer. Turmeric has a long history of use in Ayurvedic medicine for the treatment of inflammatory disorders. Recent studies on the efficacy and therapeutic applicability of turmeric have suggested that the active ingredient of tumeric is curcumin. Further, compelling evidence has shown that curcumin has the ability to inhibit inflammatory cell proliferation, invasion, and angiogenesis through multiple molecular targets and mechanisms of action. Curcumin is safe, non-toxic, and mediates its anti-inflammatory effects through the down-regulation of inflammatory transcription factors, cytokines, redox status, protein kinases, and enzymes that all promote inflammation. In addition, curcumin induces apoptosis through mitochondrial and receptor-mediated pathways, as well as activation of caspase cascades. In the current study, the anti-inflammatory effects of curcumin were evaluated relative to various chronic inflammatory diseases. Based on the available pharmacological data obtained from in vitro and in vivo research, as well as clinical trials, an opportunity exists to translate curcumin into clinics for the prevention of inflammatory diseases in the near future.

    Objectives Erythrocyte sedimentation rate (ESR) and serum level of C-reactive protein (CRP) are the acute phase reactants most commonly determined in patients with rheumatic diseases. The indices are affected by different factors, but both of them are applied for evaluation of the disease activity in patients with inflammatory disorders of the musculoskeletal system. Material and methods The authors compared the results of ESR and CRP, which were carried out during routine diagnosis in 200 patients admitted to the Department of Rheumatology. Results A significant correlation between ESR and CRP was found (ESR after 1 h/CRP: correlation coefficient 0.6944, ESR after 2 h/CRP: correlation coefficient 0.6126). There was no difference in ESR or CRP between male and female patients, and patients older than 40 years had higher ESR and CRP. Conclusions The obtained results support the usefulness of both indices in the clinical practice of rheumatologists.

    Overweight and obesity are increasing worldwide and now reach about one-third of the world's population. Obesity also involves patients with inflammatory arthritis. Knowing the impact of obesity on rheumatic diseases (rheumatoid arthritis, ankylosing spondylitis and psoriatic arthritis) is thus an important issue. This article first reviews the epidemiological and clinical data available on obesity in inflammatory rheumatic diseases, that is, its impact on incident disease, disease characteristics and the therapeutic response. The second part of this review gives an overview of the factors potentially involved in the specifics of inflammatory arthritis in patients with obesity, such as limitations in the clinical assessment, diet, microbiota and adipokines.

    It is well known that host immunity plays an important role in the defense against colorectal cancer (CRC) progression. The effects of autoimmune diseases, such as rheumatic disease (RD) in which the immune system is deregulated, on this immunity have not been fully investigated. The medical records of 1299 consecutive patients diagnosed with primary colorectal cancer who underwent surgical resection were retrospectively reviewed. The clinicopathologic factors of 28 subjects with RD (RD group) were compared with those of 1271 patients without RD (non-RD group). Compared to the non-RD group, the RD group was typified by a predominance of females (P < 0.01), older age (P < 0.01), and a lower incidence of rectal cancer (P = 0.02). Although no difference was observed between the groups in terms of TNM classification, disease-free and overall survival were significantly poorer in the RD group in both univariate and multivariate analyses. Subjects who had RD for more than 10 years tended to have a higher frequency of lymph node metastasis (P = 0.06) and a significantly higher incidence of synchronous distant metastasis (P = 0.035) at the time of cancer diagnosis. RD was associated with a significantly poorer prognosis of colorectal cancer, suggesting that deregulation of the immune system by autoimmune diseases may adversely affect the host immune defense against colorectal cancer progression.

    2016-01-01

    Inflammation response plays an important role in host survival, and it also leads to acute and chronic inflammatory diseases such as rheumatoid arthritis, bowel diseases, allergic rhinitis, asthma, atopic dermatitis and various neurodegenerative diseases. During the course of inflammation, the ROS level increases. In addition to ROS, several inflammatory mediators produced at the site lead to numerous cell-mediated damages. Inflammatory bowel disease (IBD), including ulcerative colitis and Crohn's disease, is a chronic intestinal disorder resulting from a dysfunctional epithelial, innate and adaptive immune response to intestinal microorganisms. The methods involving indomethacin-induced enterocolitis in rats with macroscopic changes of IBD, myeloperoxidase assay, microscopic (histologic) characters and biochemical parameters are discussed.

    The association of inflammation with modern human diseases (e.g. obesity, cardiovascular disease, type 2 diabetes mellitus, cancer) remains an unsolved mystery of current biology and medicine. Inflammation is a protective response to noxious stimuli that unavoidably occurs at a cost to normal tissue function. This fundamental tradeoff between the cost and benefit of the inflammatory response has been optimized over evolutionary time for specific environmental conditions. Rapid change of the human environment due to niche construction outpaces genetic adaptation through natural selection, leading increasingly to a mismatch between the modern environment and selected traits. Consequently, multiple tradeoffs that affect human physiology are not optimized to the modern environment, leading to increased disease susceptibility. Here we examine the inflammatory response from an evolutionary perspective. We discuss unique aspects of the inflammatory response and its evolutionary history that can help explain the association between inflammation and modern human diseases. PMID:22975004

    Valve repair in children is technically demanding but more desirable than valve replacement. From April 2004 to September 2005, 1 boy and 8 girls with rheumatic heart disease, aged 2-13 years (median, 9 years), underwent valve repair for isolated mitral regurgitation in 5, combined mitral and aortic regurgitation in 2, mitral stenosis in 1, and mitral regurgitation associated with atrial septal defect in 1. Chordal shortening in 7, annular plication in 6, commissurotomy in 1, reconstruction of commissural leaflets in 7 were performed for mitral valve disease. Plication and reattachment of the aortic cusps was carried out in 2 patients. Annuloplasty rings were not used. All patients survived the operation, 8 had trivial or mild residual mitral regurgitation, and 1 had trivial aortic regurgitation. Mean left atrial pressure decreased from 14 to 7 mm Hg postoperatively. During follow-up of 3-18 months, all children were asymptomatic and enjoyed normal activity. None required reoperation. In addition to chordal shortening and annular plication, reconstruction of the commissural leaflets is considered the most important aspect of valve repair. It can be achieved without annuloplasty rings, giving good early and midterm results. PMID:18381871

    Pain is associated with the different types of rheumatic syndromes because it is often the most troubling symptom of patients affected by any of these diseases. Some risk factors clearly play a major role in the clinical expression of pain and related syndromes, including genetics, age, gender, co-morbidities, traumas and psychological patterns, but there are no specific clinical, laboratory or neuroimaging markers that can indicate why and when a patient's localised pain will become chronic and widespread. Any type of pain must be treated not only appropriately, but also rapidly because the likelihood of developing some form of chronic pain is related to the duration of the peripheral pain stimulus. Chronic pain inevitably has a major impact on patients' quality of life because the loss of function undermines their ability to do everyday activities. Pain can be most effectively treated by carefully selecting various pharmacological and non-pharmacological interventions based on the characteristics of the pain itself, disease factors, psychological coping abilities, and lifestyle.

    Biomarkers are needed to guide treatment decisions for patients with rheumatic diseases. Although the phenotypic and functional analysis of immune cells is an appealing strategy for understanding immune-mediated disease processes, immune cell profiling currently has no role in clinical rheumatology. New technologies, including mass cytometry, gene expression profiling by RNA sequencing (RNA-seq) and multiplexed functional assays, enable the analysis of immune cell function with unprecedented detail and promise not only a deeper understanding of pathogenesis, but also the discovery of novel biomarkers. The large and complex data sets generated by these technologies—big data—require specialized approaches for analysis and visualization of results. Standardization of assays and definition of the range of normal values are additional challenges when translating these novel approaches into clinical practice. In this Review, we discuss technological advances in the high-dimensional analysis of immune cells and consider how these developments might support the discovery of predictive biomarkers to benefit the practice of rheumatology and improve patient care.

    The innate immune system is the first line of host defense against infection and is comprised of humoral and cellular mechanisms that recognize potential pathogens within minutes or hours of entry. The effector components of innate immunity include epithelial barriers, phagocytes, and natural killer cells, as well as cytokines and the complement system. Complement plays an important role in the immediate response against microorganisms, including Streptococcus sp. The lectin pathway is one of three pathways by which the complement system can be activated. This pathway is initiated by the binding of mannose-binding lectin (MBL), collectin 11 (CL-K1), and ficolins (Ficolin-1, Ficolin-2, and Ficolin-3) to microbial surface oligosaccharides and acetylated residues, respectively. Upon binding to target molecules, MBL, CL-K1, and ficolins form complexes with MBL-associated serine proteases 1 and 2 (MASP-1 and MASP-2), which cleave C4 and C2 forming the C3 convertase (C4b2a). Subsequent activation of complement cascade leads to opsonization, phagocytosis, and lysis of target microorganisms through the formation of the membrane-attack complex. In addition, activation of complement may induce several inflammatory effects, such as expression of adhesion molecules, chemotaxis and activation of leukocytes, release of reactive oxygen species, and secretion of cytokines and chemokines. In this chapter, we review the general aspects of the structure, function, and genetic polymorphism of lectin-pathway components and discuss most recent understanding on the role of the lectin pathway in the predisposition and clinical progression of Rheumatic Fever.

    Stem cells have their origins in the embryo and during the process of organogenesis, these differentiate into specialized cells which mature to form tissues. In addition, stem cell are characterized by an ability to indefinitely self renew. Stem cells are broadly classified into embryonic stem cells and adult stem cells. Adult stem cells can be genetically reprogrammed to form pluripotent stem cells and exist in an embroyonic like state. In the early phase of embryogenesis, human embryonic stem cells only exist transiently. Adult stem cells are omnipresent in the body and function to regenerate during the process of apoptosis or tissue repair. Hematopoietic stem cells (HSC) are adult stem cells that form blood and immune cells. Autoimmune responses are sustained due to the perennial persistence of tissue self autoantigens and/or auto reactive lymphocytes. Immune reset is a process leading to generation of fresh self-tolerant lymphocytes after chemotherapy induced elimination of self or autoreactive lymphocytes. This forms the basis for autologous HSC transplantation (HSCT). In the beginning HSCT had been limited to refractory autoimmune rheumatic diseases (AIRD) due to concern about transplant related mortality and morbidity. However HSCT for AIRD has come a long way with better understanding of patient selection, conditioning regime and supportive care. In this narrative review we have examined the available literature regarding the HSCT use in AIRD. PMID:27011918

    Rheumatic heart disease (RHD) affects at least 32.9 million people worldwide and ranks as a leading cause of death and disability in low-income and middle-income countries (LMICs). Echocardiographic screening has been demonstrated to be a powerful tool for early RHD detection, and holds potential for global RHD control. However, national screening programmes have not emerged. Major barriers to implementation include the lack of human and financial resources in LMICs. Here, we focus on recent research advances that could make echocardiographic screening more practical and affordable, including handheld echocardiography devices, simplified screening protocols and task shifting of echocardiographic screening to non-experts. Additionally, we highlight some important remaining questions before echocardiographic screening can be widely recommended, including demonstration of cost-effectiveness, assessment of the impact of screening on children and communities, and determining the importance of latent RHD. While a single strategy for echocardiographic screening in all high-prevalence areas is unlikely, we believe recent advancements are bringing the public health community closer to developing sustainable programmes for echocardiographic screening.

    The first biological therapeutics in rheumatology are approaching patent expiration, encouraging development of 'follow-on' versions, known as 'biosimilars'. Biological agents range from simple replacement hormones to complex monoclonal antibodies and soluble receptors: large, intricate proteins with unique tertiary and quaternary structures that are inherently difficult to replicate. Post-translational modifications, such as glycosylation, may occur from changes in cell lines and/or manufacturing processes, resulting in products that are highly similar, but not identical, to approved 'reference' agents, hence, the term 'biosimilar', rather than 'bioidentical'. Even minor modifications in manufacturing processes, which iteratively occur with reference products due to improvements in efficiency, scale up to meet commercial demands or changes in manufacturing sites, may alter biological function and/or immunogenicity, potentially changing their safety and efficacy profile. As biosimilars are now in randomised controlled trials for treatment of rheumatic diseases, rheumatologists face decisions regarding equipoise and will need to consider their clinical use versus reference products. A clear understanding of the inherent differences between reference antibodies and biosimilars, their clinical implications and the processes governing regulation, approval and clinical use of biosimilars, is paramount. A panel of international experts in the field of rheumatology recently convened to evaluate and discuss these issues. PMID:23253920

    Objective Rheumatic diseases have some common symptoms. Extensive gene expression studies, accumulated thus far, have successfully identified signature molecules for each rheumatic disease, individually. However, whether there exist shared factors across rheumatic diseases has yet to be tested. Methods We collected and utilized 6 public microarray datasets covering 4 types of representative rheumatic diseases including rheumatoid arthritis, systemic lupus erythematosus, ankylosing spondylitis, and osteoarthritis. Then we detected overlaps of differentially expressed genes across datasets and performed a meta-analysis aiming at identifying common differentially expressed genes that discriminate between pathological cases and normal controls. To further gain insights into the functions of the identified common differentially expressed genes, we conducted gene ontology enrichment analysis and protein-protein interaction analysis. Results We identified a total of eight differentially expressed genes (TNFSF10, CX3CR1, LY96, TLR5, TXN, TIA1, PRKCH, PRF1), each associated with at least 3 of the 4 studied rheumatic diseases. Meta-analysis warranted the significance of the eight genes and highlighted the general significance of four genes (CX3CR1, LY96, TLR5, and PRF1). Protein-protein interaction and gene ontology enrichment analyses indicated that the eight genes interact with each other to exert functions related to immune response and immune regulation. Conclusion The findings support that there exist common factors underlying rheumatic diseases. For rheumatoid arthritis, systemic lupus erythematosus, ankylosing spondylitis and osteoarthritis diseases, those common factors include TNFSF10, CX3CR1, LY96, TLR5, TXN, TIA1, PRKCH, and PRF1. In-depth studies on these common factors may provide keys to understanding the pathogenesis and developing intervention strategies for rheumatic diseases. PMID:26352601

    Advances in our understanding of the cellular and molecular mechanisms in rheumatic disease fostered the advent of the targeted therapeutics era. Intense research activity continues to increase the number of potential targets at an accelerated pace. In this review, examples of promising targets and agents that are at various stages of clinical development are described. Cytokine inhibition remains at the forefront with the success of tumor necrosis factor blockers, and biologics that block interleukin-6 (IL-6), IL-17, IL-12, and IL-23 and other cytokines are on the horizon. After the success of rituximab and abatacept, other cell-targeted approaches that inhibit or deplete lymphocytes have moved forward, such as blocking BAFF/BLyS (B-cell activation factor of the tumor necrosis factor family/B-lymphocyte stimulator) and APRIL (a proliferation-inducing ligand) or suppressing T-cell activation with costimulation molecule blockers. Small-molecule inhibitors might eventually challenge the dominance of biologics in the future. In addition to plasma membrane G protein-coupled chemokine receptors, small molecules can be designed to block intracellular enzymes that control signaling pathways. Inhibitors of tyrosine kinases expressed in lymphocytes, such as spleen tyrosine kinase and Janus kinase, are being tested in autoimmune diseases. Inactivation of the more broadly expressed mitogen-activated protein kinases could suppress inflammation driven by macrophages and mesenchymal cells. Targeting tyrosine kinases downstream of growth factor receptors might also reduce fibrosis in conditions like systemic sclerosis. The abundance of potential targets suggests that new and creative ways of evaluating safety and efficacy are needed. PMID:19232066

    Understanding disease susceptibility factors and gene-environment interactions may offer valuable insights into the biological mechanisms for the etiology of rheumatic diseases. Defining the contributions of genetic and environmental factors to the pathogenesis of rheumatic diseases such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and ankylosing spondylitis (AS), may have important implications for understanding risk prediction, pathogenic mechanisms, cellular pathways, drug discovery, and prevention strategies. However, rheumatic diseases offer distinct challenges to researchers due to heterogeneity in disease phenotypes, low disease incidence, and geographic variation in both genetic and environmental factors. Emerging research areas, including epigenetics, metabolomics, and the microbiome, may provide additional links between genetic and environmental risk factors in rheumatic disease pathogenesis. This article reviews the methods used to establish genetic and environmental risk factors and to study gene-environment interactions in rheumatic diseases and provides specific examples of successes and challenges for identifying gene-environment interactions in RA, SLE, and AS. Finally, we describe how emerging research strategies may build upon previous discoveries as well as future challenges. PMID:25437282

  8. Taurine and inflammatory diseases.

    PubMed

    Marcinkiewicz, Janusz; Kontny, Ewa

    2014-01-01

    Taurine (2-aminoethanesulfonic acid) is the most abundant free amino acid in humans and plays an important role in several essential biological processes such as bile acid conjugation, maintenance of calcium homeostasis, osmoregulation and membrane stabilization. Moreover, attenuation of apoptosis and its antioxidant activity seem to be crucial for the cytoprotective effects of taurine. Although these properties are not tissue specific, taurine reaches particularly high concentrations in tissues exposed to elevated levels of oxidants (e.g., inflammatory cells). It suggests that taurine may play an important role in inflammation associated with oxidative stress. Indeed, at the site of inflammation, taurine is known to react with and detoxify hypochlorous acid generated by the neutrophil myeloperoxidase (MPO)-halide system. This reaction results in the formation of less toxic taurine chloramine (TauCl). Both haloamines, TauCl and taurine bromamine (TauBr), the product of taurine reaction with hypobromous acid (HOBr), exert antimicrobial and anti-inflammatory properties. In contrast to a well-documented regulatory role of taurine and taurine haloamines (TauCl, TauBr) in acute inflammation, their role in the pathogenesis of inflammatory diseases is not clear. This review summarizes our current knowledge concerning the role of taurine, TauCl and TauBr in the pathogenesis of inflammatory diseases initiated or propagated by MPO-derived oxidants. The aim of this paper is to show links between inflammation, neutrophils, MPO, oxidative stress and taurine. We will discuss the possible contribution of taurine and taurine haloamines to the pathogenesis of inflammatory diseases, especially in the best studied example of rheumatoid arthritis.

    OBJECTIVE: Immunosuppressed patients are at risk of microsporidiosis, and this parasitosis has an increased rate of dissemination in this population. Our objective was to evaluate the presence of microsporidiosis and other intestinal parasites in rheumatic disease patients undergoing anti-tumor necrosis factor/disease-modifying anti-rheumatic drug treatment. METHODS: Ninety-eight patients (47 with rheumatoid arthritis, 31 with ankylosing spondylitis and 11 with psoriatic arthritis) and 92 healthy control patients were enrolled in the study. Three stool samples and cultures were collected from each subject. RESULTS: The frequency of microsporidia was significantly higher in rheumatic disease patients than in control subjects (36 vs. 4%, respectively; p<0.0001), as well as in those with rheumatic diseases (32 vs. 4%, respectively; p<0.0001), ankylosing spondylitis (45 vs. 4%, respectively; p<0.0001) and psoriatic arthritis (40 vs. 4%, respectively; p<0.0001), despite a similar social-economic class distribution in both the patient and control groups (p = 0.1153). Of note, concomitant fecal leukocytes were observed in the majority of the microsporidia-positive patients (79.5%). Approximately 80% of the patients had gastrointestinal symptoms, such as diarrhea (26%), abdominal pain (31%) and weight loss (5%), although the frequencies of these symptoms were comparable in patients with and without this infection (p>0.05). Rheumatoid arthritis, ankylosing spondylitis and psoriatic arthritis disease activity parameters were comparable in both groups (p>0.05). The duration of anti-tumor necrosis factor/disease-modifying anti-rheumatic drugs and glucocorticoid use were also similar in both groups. CONCLUSION: We have documented that microsporidiosis with intestinal mucosa disruption is frequent in patients undergoing concomitant anti-tumor necrosis factor/disease-modifying anti-rheumatic drug therapy.

    ETIOLOGY OF DEGENERATIVE JOINT DISEASES: Etiology of degenerative joint diseases is still not clearly understood and there is no specific management for this group of diseases. Various pathological conditions cause damage of the articular cartilage and lead to clinically and radiographically recognized impairment. Biomechanical, metabolic, genetic factors, inflammation and other risk factors contribute to development of osteoarthrosis. PATHOPHYSIOLOGY OF DEGENERATIVE JOINT DISEASES: Osteoarthrosis is characterized by progressive erosion of articular cartilage and bone overgrowth at the joint margins. Cartilage integrity requires balance between synthesis and degradation of matrix components. Chondrocytes react to various mechanical and chemical stresses in order to stabilize and restore the tissue. Failures in stabilizing and restoring the tissue lead to cartilage degeneration that may be irreversibile. For better understanding of conservative management of degenerative joint diseases it is important to know the impact of pathophysiology mechanisms on development of degenerative joint diseases. There is great variability in the rate of progression of erosive processes in articular cartilage in clinical, radiographic signs and course of the disease. This is in relation with many factors, as well as with management and response to therapy. TREATMENT OF DEGENERATIVE JOINT DISEASES: Treatment should vary depending on the severity of disease and patient's expectations and level of activity. Besides analgesic and anti-inflammatory drugs, conventional and not conventional treatment and techniques can be used for management of osteoarthrosis. Physical therapy and exercises are very important for maintaining muscle strength, joint stability and mobility, but should be closely monitored for optimal efficacy. PMID:12037935

    2014-01-01

    Beyond its critical function in calcium homeostasis, vitamin D has recently been found to play an important role in the modulation of the immune/inflammation system via regulating the production of inflammatory cytokines and inhibiting the proliferation of proinflammatory cells, both of which are crucial for the pathogenesis of inflammatory diseases. Several studies have associated lower vitamin D status with increased risk and unfavorable outcome of acute infections. Vitamin D supplementation bolsters clinical responses to acute infection. Moreover, chronic inflammatory diseases, such as atherosclerosis-related cardiovascular disease, asthma, inflammatory bowel disease, chronic kidney disease, nonalcoholic fatty liver disease, and others, tend to have lower vitamin D status, which may play a pleiotropic role in the pathogenesis of the diseases. In this article, we review recent epidemiological and interventional studies of vitamin D in various inflammatory diseases. The potential mechanisms of vitamin D in regulating immune/inflammatory responses in inflammatory diseases are also discussed. PMID:24971027

Physical exercise can play a crucial role in the treatment of rheumatic diseases, optimizing both physical and mental health, enhancing energy, decreasing fatigue and improving sleep. An exercise program for patients with rheumatic diseases aims to preserve or restore a range of motion of the affected joints, to increase muscle strength and endurance, and to improve mood and decrease health risks associated with a sedentary lifestyle. In this editorial I describe the benefits of the exercise on physical limitations and fatigue in rheumatic diseases that seem to have a short and long-term effectiveness.

    Musculoskeletal pain is a very common complaint, affecting 30–40% of the European population. It is estimated that approximately 400,000 Poles suffer from inflammatory rheumatic diseases, such as rheumatoid arthritis, ankylosing spondylitis and psoriatic arthritis, and a vast majority of those affected are working-age individuals. Patients with suspected arthritis require prompt diagnosis and treatment, as any delays may result in irreversible joint destruction and disability. Currently in Poland, the lag time between the onset of symptoms and diagnosis is, on average, as much as 35 weeks. In this paper, we review the current state of specialist rheumatology care in Poland and propose a reorganised care model that includes early diagnosis of inflammatory arthritis. The main goal we wish to achieve with our reorganised model is to enhance access to outpatient specialist rheumatology care for patients with suspected arthritis. We believe that our model should make it possible to considerably reduce the lag time between GP referral and the diagnosis and treatment by a rheumatologist to as little as 3 to 4 weeks. This article provides a proposal of changes that would achieve this goal and is a summary of the report published by the Institute of Rheumatology in September 2014.

    Inflammatory joint diseases are of considerable socio-economic significance. However, mechanisms of cartilage destruction are so far only poorly understood. This review is dedicated to reactive oxygen species (ROS) like superoxide anion radicals, hydrogen peroxide, singlet oxygen, hypochlorous acid, hydroxyl radicals and nitric oxide that are generated under inflammatory conditions and also to their potential contribution to cartilage degradation. First, the relevance of rheumatic diseases and potential mechanisms of cartilage degradation are discussed in this review, followed by the description of the chemical constituents and the molecular architecture of articular cartilage as well as the different cell types that play a role in inflammation and cartilage destruction. Methods of the assessment of cartilage degeneration are also shortly discussed. In the main chapter of this review the characteristics of individual ROS, their generation under in vivo conditions as well as their reactivities with individual cartilage components are discussed. Because of the low selectivity of ROS, useful "markers" of cartilage degradation allowing the differentiation of effects induced by individual ROS are also discussed. In the last chapter current therapeutic concepts of the treatment of rheumatic diseases are reviewed. The recently developed "anti-TNF-alpha" therapy that is primarily directed against neutrophilic granulocytes that are powerful sources of ROS and, therefore, important mediators of joint degeneration are emphasised.

    It has been recognized that during chronic inflammatory systemic diseases (CIDs) maladaptations of the immune, nervous, endocrine and reproductive system occur. Maladaptation leads to disease sequelae in CIDs. The ultimate reason of disease sequelae in CIDs remained unclear because clinicians do not consider bodily energy trade-offs and evolutionary medicine. We review the evolution of physiological supersystems, fitness consequences of genes involved in CIDs during different life-history stages, environmental factors of CIDs, energy trade-offs during inflammatory episodes and the non-specificity of CIDs. Incorporating bodily energy regulation into evolutionary medicine builds a framework to better understand pathophysiology of CIDs by considering that genes and networks used are positively selected if they serve acute, highly energy-consuming inflammation. It is predicted that genes that protect energy stores are positively selected (as immune memory). This could explain why energy-demanding inflammatory episodes like infectious diseases must be terminated within 3–8 weeks to be adaptive, and otherwise become maladaptive. Considering energy regulation as an evolved adaptive trait explains why many known sequelae of different CIDs must be uniform. These are, e.g. sickness behavior/fatigue/depressive symptoms, sleep disturbance, anorexia, malnutrition, muscle wasting—cachexia, cachectic obesity, insulin resistance with hyperinsulinemia, dyslipidemia, alterations of steroid hormone axes, disturbances of the hypothalamic-pituitary-gonadal (HPG) axis, hypertension, bone loss and hypercoagulability. Considering evolved energy trade-offs helps us to understand how an energy imbalance can lead to the disease sequelae of CIDs. In the future, clinicians must translate this knowledge into early diagnosis and symptomatic treatment in CIDs. PMID:26817483

    Inflammatory eye diseases are an important manifestation of many pediatric rheumatologic conditions. Early screening and diagnosis are imperative as these illnesses can not only result in significant visual morbidity but also be an indicator of systemic inflammation. Time to presentation of ocular inflammation varies significantly and can range from many years prior to the onset of systemic symptoms to well after the diagnosis of the rheumatologic disorder. Due to this variability in presentation, careful monitoring by an ophthalmologist is vital to preventing ocular complications and preserving vision. Both local and systemic immunosuppressive medications have been effective in the management of ocular disease. In this review, we will focus on the known ophthalmologic manifestations of common pediatric rheumatologic diseases and discuss recent advances in therapeutic considerations for these conditions.

    The management of rheumatic conditions, including those occurring in children, has improved dramatically over the last decade following the introduction of biologic disease-modifying anti-rheumatic drugs (bDMARDS) into the therapeutic arsenal. The benefits have been realised in multiple aspects of disease including signs and symptoms, bone and cartilage destruction, disability and quality of life. Overall, bDMARDS have an acceptable safety profile in the short to medium term in adults and children, however, that following longer term use remains unclear. As these drugs target key signalling molecules and cells of the immune system, adverse events are not unanticipated. In this review we will discuss pulmonary complications of biologic therapies used in the management of rheumatic diseases in both children and adults. PMID:23462434

    Insights into inflammatory bowel disease (IBD) are advancing rapidly owing to immunologic investigations of a plethora of animal models of intestinal inflammation, ground-breaking advances in the interrogation of diseases that are inherited as complex genetic traits, and the development of culture-independent methods to define the composition of the intestinal microbiota. These advances are bringing a deeper understanding to the genetically determined interplay between the commensal microbiota, intestinal epithelial cells, and the immune system and the manner in which this interplay might be modified by relevant environmental factors in the pathogenesis of IBD. This review examines these interactions and, where possible, potential lessons from IBD-directed, biologic therapies that may allow for elucidation of pathways that are central to disease pathogenesis in humans.

    Rheumatic heart disease (RHD) is an inflammatory disease that develops following streptococcal infections. IL10 helps to balance immune responses to pathogens. IL10 polymorphisms have been associated with RHD, although results remain inconclusive. Our aim was to investigate the association between IL10 polymorphisms and RHD in Saudi Arabian patients. IL10 promoter polymorphisms (-1082A/G, -829C/T, and -592C/A) were genotyped in 118 RHD patients and 200 matched controls using the TaqMan allelic discrimination assay. There was a significant difference in IL10-1082 genotype frequency between patients and controls (p = 0.01). -1082G allele carriage (GG+GA vs AA) and the (-1082, -819, -592) GCC haplotype carriage were associated with an increased risk of RHD (p = 0.004, OR 2.1, 95% CIs 1.7-3.4 and p = 0.004, OR 2, 95% CIs 1.3-3.4, respectively). The ACC haplotype was associated with a decrease in RHD risk (p = 0.015, OR 0.6, 95% CIs 0.4-0.9). IL10 promoter polymorphisms may play an important role in the development of RHD and provide an opportunity for therapeutic stratification. PMID:26255050

    2009-01-01

    A better understanding of cytokine biology over the last two decades has allowed the successful development of cytokine inhibitors against tumour necrosis factor and interleukin (IL)-1 and IL-6. The introduction of these therapies should be considered a breakthrough in the management of several rheumatic diseases. However, many patients will exhibit no or only partial response to these therapies, thus emphasising the importance of exploring other therapeutic strategies. In this article, we review the most recent information on novel cytokines that are often members of previously described cytokine families such as the IL-1 superfamily (IL-18 and IL-33), the IL-12 superfamily (IL-27 and IL-35), the IL-2 superfamily (IL-15 and IL-21), and IL-17. Several data derived from experimental models and clinical samples indicate that some of these cytokines contribute to the pathophysiology of arthritis and other inflammatory diseases. Targeting of some of these cytokines has already been tested in clinical trials with interesting results. PMID:19519923

    This study aimed to determine the prevalence of musculoskeletal (MSK) pain and rheumatic diseases in the Raramuri population (also known as Tarahumaras) who are an indigenous group in the northern state of Chihuahua in Mexico. We used the Community-Oriented Program for Control of Rheumatic Diseases (COPCORD) methodology. An analytical cross-sectional study was conducted including indigenous Raramuri aged ≥18 years from communities settled in Chihuahua City. Subjects with positive MSK pain were evaluated by primary care physicians and rheumatologists. Demographic and occupational factors such as gender and job type associated with rheumatic disease were investigated. A total of 380 indigenous Raramuri (mean age 33.6 ± 13.1 years; 37.9 % male) were interviewed. Seventy-six individuals (20 %) reported MSK pain in the last 7 days. Pain intensity was reported as "severe" and "the most severe" in 30 % of the cases. Fifty-six individuals (14.7 %) reported pain in the past and 86 (22.6 %) had either past or current pain. The prevalence of rheumatic diseases was 10.5 %. Diagnosed diseases were osteoarthritis (6.6 %), low back pain (1.6 %), spondyloarthritis (0.8 %), rheumatoid arthritis (0.5 %), non-specific arthritis (0.5 %), rheumatic regional pain syndromes (0.3 %), and fibromyalgia (0.3 %). Rheumatic disease was associated with the following variables: age (odds ratio (OR) 1.04, 95 % confidence interval (CI) 1.02-1.08; p = 0.006), family history of rheumatic symptoms (OR 6.9; 95 % CI 2.6-18.7; p < 0.001), and Health Assessment Questionnaire-Disability Index (OR 28.9; 95 % CI 2.8-289.7; p < 0.001). A high prevalence of non-traumatic MSK pain suggests the need for a rheumatic disease prevention program in the Raramuri people in Chihuahua, Mexico. PMID:26956444

    Epidemiology is the study of the distribution and determinants of disease in human populations. Over the past decade there has been considerable progress in our understanding of the fundamental descriptive epidemiology (levels of disease frequency: incidence and prevalence, comorbidity, mortality, trends over time, geographic distributions, and clinical characteristics) of the rheumatic diseases. This progress is reviewed for the following major rheumatic diseases: rheumatoid arthritis (RA), juvenile rheumatoid arthritis, psoriatic arthritis, osteoarthritis, systemic lupus erythematosus, giant cell arteritis, polymyalgia rheumatica, gout, Sjögren's syndrome, and ankylosing spondylitis. These findings demonstrate the dynamic nature of the incidence and prevalence of these conditions – a reflection of the impact of genetic and environmental factors. The past decade has also brought new insights regarding the comorbidity associated with rheumatic diseases. Strong evidence now shows that persons with RA are at a high risk for developing several comorbid disorders, that these conditions may have atypical features and thus may be difficult to diagnose, and that persons with RA experience poorer outcomes after comorbidity compared with the general population. Taken together, these findings underscore the complexity of the rheumatic diseases and highlight the key role of epidemiological research in understanding these intriguing conditions. PMID:19519924

    We have estimated the clinical effectiveness of several regimes and ways of low power laser therapy (LT) on the basis of a double 'blind', placebo-controlling randomizing comparative test in 454 patients with rheumatic diseases (RD). LT for RD has a well-expressed placebo effect. The level of clinical effect of LT for RD is not so high. We couldn't achieve 'a considerable improvement' in any cases, 'an improvement' was secured in only 18 percent. LT should be viewed as a symptomatic means, with a primary anesthetic and feebly expressed anti-inflammatory effect, which can not influence the course of the rheumatoid process. Only in 15 percent of patients with RD, a sufficient functioning of hemo-salivary barrier was observed, the latter providing a reserve for adaption mechanism, which leads under the influence of stressor agents of medium strength not only to anesthetic, but also to moderately expressed anti- inflammatory effect.

    A survey of school children aged 5 to 16 years living in a rural community of the hill region of Nepal, situated about 15-22 km outside Kathmandu city, was conducted to determine the prevalence of rheumatic fever (RF) and rheumatic heart disease (RHD). Of the 4,816 eligible children enrolled in the selected schools, 4,452 (92.4%) were examined. WHO expert committee criteria (1966) was used for the diagnosis and classification of rheumatic fever. Chest x-ray, electro-cardiography, echocardiography and Doppler study were done in all suspected cases of rheumatic heart disease. Six cases of RHD (1 pure mitral stenosis, 3 mitral regurgitation and 2 combined mitral stenosis and regurgitation) were identified giving overall prevalence rate of 1.35 per thousand. No case with active rheumatic fever could be identified. This is the first study on prevalence of RF/RHD in Nepal. The prevalence rate is lower than that reported from neighbouring countries.

    From the perspective of patients with rheumatic diseases, the reduction of inflammatory disease activity alone is not a sufficient treatment goal. In addition the functional health and participation also have to be improved. Starting with the first symptoms the empowerment for the self-management of the disease is important for the patients; therefore, the established treat to target-strategy has to be expanded by the functional dimension to treat to participation. The position paper of the German Society for Rheumatology (GSR) summarizes the relevant fields of the multiprofessional action that is frequently necessary. This includes the acquirement of function-related competencies during training, further education and advanced training as well as implementation in the everyday practice of patient care. Furthermore, the GSR acknowledges the need for research related to functional and sociomedical consequences of rheumatic diseases and to individual and combined function-related programs in outpatient and inpatient care in rheumatology.

    Inflammatory bowel disease (IBD), including Crohn’s disease and ulcerative colitis, is characterized by chronic relapsing intestinal inflammation. It has been a worldwide health-care problem with a continually increasing incidence. It is thought that IBD results from an aberrant and continuing immune response to the microbes in the gut, catalyzed by the genetic susceptibility of the individual. Although the etiology of IBD remains largely unknown, it involves a complex interaction between the genetic, environmental or microbial factors and the immune responses. Of the four components of IBD pathogenesis, most rapid progress has been made in the genetic study of gut inflammation. The latest internationally collaborative studies have ascertained 163 susceptibility gene loci for IBD. The genes implicated in childhood-onset and adult-onset IBD overlap, suggesting similar genetic predispositions. However, the fact that genetic factors account for only a portion of overall disease variance indicates that microbial and environmental factors may interact with genetic elements in the pathogenesis of IBD. Meanwhile, the adaptive immune response has been classically considered to play a major role in the pathogenesis of IBD, as new studies in immunology and genetics have clarified that the innate immune response maintains the same importance in inducing gut inflammation. Recent progress in understanding IBD pathogenesis sheds lights on relevant disease mechanisms, including the innate and adaptive immunity, and the interactions between genetic factors and microbial and environmental cues. In this review, we provide an update on the major advances that have occurred in above areas. PMID:24415861

    A rheumatic disease can severely impair a person's quality of life. The degree of impairment, however, is not closely related to objective indicators of disease severity. This study investigated the influence and the interplay of core psychological factors, i.e., personality and coping, on life satisfaction in patients with rheumatic diseases. Particularly, it was tested whether coping mediates the effects of personality on life satisfaction. In a cross-sectional design, 158 patients diagnosed with a rheumatic disease completed questionnaires assessing the Big 5 personality traits (BFI-10), several disease-related coping strategies (EFK) and life satisfaction (HSWBS). Data were analyzed using a complex multiple mediation analysis with the Big 5 personality traits as predictors, coping strategies as mediators and life satisfaction as outcome. All personality traits and seven of the nine coping strategies were associated with life satisfaction (rs > |0.16|, ps ≤ 0.05). The mediation analysis revealed that personality traits had no direct, but rather indirect effects on life satisfaction through coping. Neuroticism had a negative indirect effect on life satisfaction through less active problem solving and more depressive coping (indirect effects > -0.03, ps < 0.05). Extraversion, agreeableness, and conscientiousness had positive indirect effects on life satisfaction through more active problem solving, less depressive coping and/or a more active search for social support (indirect effects > 0.06, ps < 0.05). Personality and coping play a role in adjustment to rheumatic diseases. The interplay of these variables should be considered in psychological interventions for patients with rheumatic diseases.

    Introduction Rheumatic diseases are becoming more and more common in Poland with the ageing of the population. Nearly 18% of the total hospital admissions in Poland result from rheumatic diseases, which was equivalent to 350 thousand cases in the year 2008. These diseases tend to last for many decades, decreasing both the quality of life and income of the patients as well as increasing the medical institutions’ workload and society's financial burden. The aim of the study was to determine whether the medical care parameters in a rheumatic disease hospital ward show any significant differences among different patient age groups – especially such that would support taking them into account as a basis for adjusting the financial coverage level of medical services. Material and methods Data on hospitalizations at the Rheumatic Diseases Ward of Wroclaw University Hospital in Wroclaw in the years 2009–2015 were analyzed, taking into account the age groups, number of hospital admissions, their duration and causes. Relevant statistical data analysis was performed. Discussion The study revealed that the number of old patients hospitalized at the rheumatic diseases ward increased over the last 6 years and that such statistically significant differences do exist: on average the old patients not only tend to stay much longer at the hospital, but also suffer from a different and more diverse spectrum of diseases in comparison to their younger counterparts. Conclusions The detected differences in medical care parameters support the need for more individualized medical care and increased cost of the hospital stay in the case of older patients. Consequently, those factors justify the necessity to increase the value of medical services in the case of old patients, possibly also taking into account the variation between age subgroups.

    Flow cytometry has emerged as an essential tool for investigators in the study of the complexity of the immune system and the examination of its role in human health and disease. This technology has developed to the point where one can readily generate a large descriptive data set that details the levels of important immune cell subsets and defines an individual immune cell signature or “Immune-cellome”. This immune cell signature would clearly display individual variation but also would change in a manner reflective of disease state. Analysis of the “immune-cellome” may provide novel insight into disease pathophysiology, provide new biomarkers of disease activity and perhaps identify therapeutic targets. In this brief review we will cover current advances in complex flow cytometry and suggest ways this may be applied to the study of rheumatic diseases. PMID:23334929

    A network of cellular interactions that involve blood leukocytes and platelets maintains vessel homeostasis. It plays a critical role in the response to invading microbes by recruiting intravascular immunity and through the generation of neutrophil extracellular traps (NETs) and immunothrombosis. Moreover, it enables immune cells to respond to remote chemoattractants by crossing the endothelial barrier and reaching sites of infection. Once the network operating under physiological conditions is disrupted, the reciprocal activation of cells in the blood and the vessel walls determines the vascular remodeling via inflammatory signals delivered to stem/progenitor cells. A deregulated leukocyte/mural cell interaction is an early critical event in the natural history of systemic inflammation. Despite intense efforts, the signals that initiate and sustain the immune-mediated vessel injury, or those that enforce the often-prolonged phases of clinical quiescence in patients with vasculitis, have only been partially elucidated. Here, we discuss recent evidence that implicates the prototypic damage-associated molecular pattern/alarmin, the high mobility group box 1 (HMGB1) protein in systemic vasculitis and in the vascular inflammation associated with systemic sclerosis. HMGB1 could represent a player in the pathogenesis of rheumatic diseases and an attractive target for molecular interventions. PMID:27242789

    Background: The Wait Time Alliance recently established wait time benchmarks for rheumatology consultations in Canada. Our aim was to quantify wait times to primary and rheumatology care for patients with rheumatic diseases. Methods: We identified patients from primary care practices in the Electronic Medical Record Administrative data Linked Database who had referrals to Ontario rheumatologists over the period 2000-2013. To assess the full care pathway, we identified dates of symptom onset, presentation in primary care and referral from electronic medical records. Dates of rheumatologist consultations were obtained by linking with physician service claims. We determined the duration of each phase of the care pathway (symptom onset to primary care encounter, primary care encounter to referral, and referral to rheumatologist consultation) and compared them with established benchmarks. Results: Among 2430 referrals from 168 family physicians, 2015 patients (82.9%) were seen by 146 rheumatologists within 1 year of referral. Of the 2430 referrals, 2417 (99.5%) occurred between 2005 and 2013. The main reasons for referral were osteoarthritis (32.4%) and systemic inflammatory rheumatic diseases (30.6%). Wait times varied by diagnosis and geographic region. Overall, the median wait time from referral to rheumatologist consultation was 74 (interquartile range 27-101) days; it was 66 (interquartile range 18-84) days for systemic inflammatory rheumatic diseases. Wait time benchmarks were not achieved, even for the most urgent types of referral. For systemic inflammatory rheumatic diseases, most of the delays occurred before referral. Interpretation: Rheumatology wait times exceeded established benchmarks. Targeted efforts are needed to promote more timely access to both primary and rheumatology care. Routine linkage of electronic medical records with administrative data may help fill important gaps in knowledge about waits to primary and specialty care. PMID:27398365

    Inflammatory disorders of childhood, such as juvenile idiopathic arthritis (JIA) and inflammatory bowel disease (IBD) are a challenge for laboratory diagnostics. Firstly, the classical inflammatory markers, such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) often inadequately reflect disease activity but on the other hand there are few specific biomarkers that can be helpful in managing these diseases. Acute phase proteins reflect the systemic inflammatory response insufficiently as their increase is only the indirect result of local inflammatory processes. Modern inflammation diagnostics aim to reflect these local processes and to allow precise monitoring of disease activity. Experimental biomarkers, such as S100 proteins can detect subclinical inflammatory activity. In addition, established laboratory parameters exist for JIA [antinuclear antibodies (ANA), rheumatoid factor (RF), antibodies against cyclic citrullinated peptide (anti-CCP)] and for chronic IBD (fecal calprotectin) that are useful in the treatment of these diseases.

    The main aim of metabolomics is to make a comprehensive study of metabolites, the intermediates of biochemical processes in living organisms. Any pathophysiological mechanism caused by disease will inevitably lead to related changes in the concentrations of specific metabolites. In line with this, metabolomics offers a promising laboratory tool for the analysis of potential diagnostic biomarkers that may be used to assess susceptibility to a disease and to evaluate the prognosis and therapeutic response to treatment. Recent data have shown that metabolomics analysis in rheumatoid arthritis has made possible more efficient diagnosis, discrimination between patients with regard to disease activity, prediction of the response to a particular treatment approach, differentiation between rheumatic disease subtypes and greater understanding of the pathophysiology of this disease. Here we characterize metabolomics as a comprehensive laboratory tool and review its potential in the diagnosis, prognosis and treatment of rheumatic diseases such as rheumatoid arthritis.

    Our patient is an 18-year-old Caucasian woman from the UK who developed severe mitral stenosis on a history of childhood acute rheumatic fever (ARF) and rheumatic heart disease (RHD). She had been reporting of her oral penicillin secondary prophylaxis regimen since diagnosis. At the age of 15 years, a new murmur was discovered during routine cardiac follow-up. An echocardiogram confirmed moderate-severe mitral stenosis. One year later, her exercise tolerance significantly deteriorated and she subsequently underwent balloon valvuloplasty of her mitral valve to good effect. Our case emphasises the evidence base supporting the use of monthly intramuscular penicillin injection to prevent ARF recurrence and RHD progression; it also emphasises the reduced efficacy of oral penicillin prophylaxis in this context. It particularly resonates with regions of low rheumatic fever endemicity. The long-term cardiac sequelae of ARF can be devastating; prescribing the most effective secondary prophylaxis regimen is essential. PMID:26531741

    The majority of rheumatic diseases belong to the group of autoimmune diseases and are associated with autoantibody production. Their etiology is not fully understood. Certain medications and environmental factors may have an influence on the occurrence of rheumatic diseases. Establishing a cause-effect relationship between a certain factor and disease induction is not always simple. It is important to administer the drug continuously or monitor exposure to a given factor in the period preceding the onset of symptoms. The lack of previously diagnosed autoimmune disease, or finally the lack of symptoms within a few weeks/months after discontinuation of the drug/cessation of exposure, is also important. The most frequently mentioned rheumatic diseases caused by drugs and environmental factors include systemic lupus erythematosus, scleroderma, systemic vasculitis, polymyositis, dermatomyositis, and Sjögren's syndrome. The objective of this study is to summarize current knowledge on rheumatic diseases induced by drugs and environmental factors. PMID:27504022

    Africa has one of the highest prevalence of heart diseases in children and young adults, including congenital heart disease (CHD) and rheumatic heart disease (RHD). We present here an extensive review of recent data from the African continent highlighting key studies and information regarding progress in CHD and RHD since 2005. Main findings include evidence that the CHD burden is underestimated mainly due to the poor outcome of African children with CHD. The interest in primary prevention for RHD has been recently re-emphasised, and new data are available regarding echocardiographic screening for subclinical RHD and initiation of secondary prevention. There is an urgent need for comprehensive service frameworks to improve access and level of care and services for patients, educational programmes to reinforce the importance of prevention and early diagnosis and a relevant research agenda focusing on the African context.

    Background Rheumatic heart disease (RHD) and HIV are prevalent diseases in sub-Saharan Africa, but little is known about their potential interrelationships. The objective of this study was to assess the prevalence of protective natural autoantibodies among patients with RHD in Uganda, and to determine whether the levels of these autoantibodies are affected by HIV status. Methods Participants were grouped according to RHD and HIV status. The three control groups (RHD − HIV −, RHD − HIV +, RHD + HIV −) were age-matched to the RHD + HIV + participants. All participants underwent HIV testing and echocardiography to evaluate for RHD. Natural autoantibody levels reactive with phosphorylcholine (PC) and malondialdehyde (MDA) were measured. Findings We enrolled 220 participants; 21 with both RHD and HIV. Ages ranged from 10 to 60 years, with female predominance (144/220, 65%). After adjusting for age and gender, HIV infection and RHD were each associated with low IgM anti-PC (HIV: p < 0.0001 and RHD: p = 0.01). A distinct HIV ∗ RHD interaction was identified (p = 0.045) with increased IgG anti-MDA levels in HIV infected subjects without RHD, whereas IgG anti-MDA levels were decreased in HIV infected subjects with RHD. Interpretation We found that HIV and RHD are associated with alterations in natural autoantibody responses previously linked to an increased risk for atherosclerosis and autoimmune inflammatory disease.

  6. Activation of mTOR (mechanistic target of rapamycin) in rheumatic diseases.

    PubMed

    Perl, Andras

    2016-03-01

    Mechanistic target of rapamycin (mTOR, also known as mammalian target of rapamycin) is a ubiquitous serine/threonine kinase that regulates cell growth, proliferation and survival. These effects are cell-type-specific, and are elicited in response to stimulation by growth factors, hormones and cytokines, as well as to internal and external metabolic cues. Rapamycin was initially developed as an inhibitor of T-cell proliferation and allograft rejection in the organ transplant setting. Subsequently, its molecular target (mTOR) was identified as a component of two interacting complexes, mTORC1 and mTORC2, that regulate T-cell lineage specification and macrophage differentiation. mTORC1 drives the proinflammatory expansion of T helper (TH) type 1, TH17, and CD4(-)CD8(-) (double-negative, DN) T cells. Both mTORC1 and mTORC2 inhibit the development of CD4(+)CD25(+)FoxP3(+) T regulatory (TREG) cells and, indirectly, mTORC2 favours the expansion of T follicular helper (TFH) cells which, similarly to DN T cells, promote B-cell activation and autoantibody production. In contrast to this proinflammatory effect of mTORC2, mTORC1 favours, to some extent, an anti-inflammatory macrophage polarization that is protective against infections and tissue inflammation. Outside the immune system, mTORC1 controls fibroblast proliferation and chondrocyte survival, with implications for tissue fibrosis and osteoarthritis, respectively. Rapamycin (which primarily inhibits mTORC1), ATP-competitive, dual mTORC1/mTORC2 inhibitors and upstream regulators of the mTOR pathway are being developed to treat autoimmune, hyperproliferative and degenerative diseases. In this regard, mTOR blockade promises to increase life expectancy through treatment and prevention of rheumatic diseases. PMID:26698023

  7. Challenges in rheumatic valvular disease: Surgical strategies for mitral valve preservation

    PubMed Central

    Antunes, Manuel J

    2015-01-01

    In developing countries, rheumatic fever and carditis still constitutes a major public health problem. Patients have special characteristics that differ from those with rheumatic mitral valve disease we still see in developed countries. They are usually young, poor, uneducated, and have low compliance to prophylaxis / therapy. In addition, they usually have great difficulty in accessing medical care. In these situations, the rate of complications associated to valve replacement is significantly increased. Alternatively, mitral valve repair is now known to achieve better long-term results in this pathology, but this was not widely recognized three or four decades ago, when first reports showed worse results after repair of rheumatic regurgitation than with degenerative valves. This has been reported by several groups in developing countries in different continents, with high incidence of repairs and excellent long term results. It is, therefore, becoming increasingly clear that, although, the results may not compare to those obtained with degenerative pathology, repair of rheumatic valves, when feasible, is the procedure of choice, especially in these underprivileged populations.

    Background The objective of the study was to evaluate the implications of different classifications of rheumatic heart disease on estimated prevalence, and to systematically assess the importance of incidental findings from echocardiographic screening among schoolchildren in Peru. Methods We performed a cluster randomized observational survey using portable echocardiography among schoolchildren aged 5 to 16 years from randomly selected public and private schools in Arequipa, Peru. Rheumatic heart disease was defined according to the modified World Health Organization (WHO) criteria and the World Heart Federation (WHF) criteria. Findings Among 1395 eligible students from 40 classes and 20 schools, 1023 (73%) participated in the present survey. The median age of the children was 11 years (interquartile range [IQR] 8–13 years) and 50% were girls. Prevalence of possible, probable and definite rheumatic heart disease according to the modified WHO criteria amounted to 19.7/1000 children and ranged from 10.2/1000 among children 5 to 8 years of age to 39.8/1000 among children 13 to 16 years of age; the prevalence of borderline/definite rheumatic heart disease according to the WHF criteria was 3.9/1000 children. 21 children (2.1%) were found to have congenital heart disease, 8 of which were referred for percutaneous or surgical intervention. Conclusions Prevalence of RHD in Peru was considerably lower compared to endemic regions in sub-Saharan Africa, southeast Asia, and Oceania; and paralleled by a comparable number of undetected congenital heart disease. Strategies to address collateral findings from echocardiographic screening are necessary in the setup of active surveillance programs for RHD.

    One of the objectives of this large scale cross-sectional study of school children of the Addis Ababa city was to assess the status of rheumatic heart disease (RHD) prophylaxis among rheumatic heart disease patients identified during the survey. Awareness about the presence of the illness in those affected and reasons for poor coverage, when detected, were also assessed. Sixty of the 9388 school children surveyed were found to have rheumatic heart disease. On interviewing parents of the children with rheumatic heart disease, ten acknowledged being informed of their children's cardiac illness. Of these parents, 15% (or 9/60) had some idea that their children had heart disease related to some form of infection. However, only two of the nine (22%) children whose parents had some idea about their disease were on regular monthly benzathine penicillin prophylaxis in the previous 12 months preceding the interview. Three (33%) of the nine children had six or fewer injections in the 12 months preceding the interview. The remaining 4 parents (44%) reported that their children took treatment that included injections only at the time of initial diagnosis several years earlier and had not had any follow up since then. Their reasons for not seeking medical care for their children included lack of information on prophylaxis, inability to pay for the treatment and distance of the health facilities. The lack of awareness and the extremely low rate of regular prophylaxis, therefore, highlight the need for an urgent control programme that takes active case detection, treatment access and health education into consideration.

  10. Cognitive-behavioural approaches to self-management in rheumatic disease.

    Patients with rheumatic disease must adjust psychosocially and behaviourally in order to manage the impact of symptoms and treatment on their daily lives, and the emotional consequences of the disease. However, patients can improve their well-being by taking a proactive role in self-management, for example by using coping strategies. Support for patient self-management from clinical teams usually comprises information and advice on disease management; however, this largely didactic approach often focuses on the biomedical aspects of rheumatic disease, without addressing how these aspects interact with psychosocial factors to influence health behaviours and thus outcomes. A cognitive-behavioural approach based on the biopsychosocial model of rheumatic disease can facilitate the identification of effective self-management strategies through collaboration between patients and clinicians. Most patients do not require intense cognitive-behavioural therapy from a clinical psychologist; rather, basic cognitive-behavioural techniques and tools could be used by rheumatology clinical teams to expand and enhance the support already offered to patients.

    Rapid advances in the understanding of endothelin as a naturally occurring peptide with developmental and regulatory roles in normal physiology, along with a number of deleterious effects under pathologic conditions (including vasoconstriction, fibrosis, vascular hypertrophy, and inflammation) have led to the development of endothelin-receptor antagonists (ERAs). Bosentan, an antagonist with dual specificity for the endothelin-receptor subtypes A and B, has been shown to be efficacious and well tolerated in placebo-controlled clinical trials and is now approved in many countries, including the US, Canada, and Europe, for treatment of pulmonary arterial hypertension (PAH), including PAH associated with rheumatic diseases. ERAs with specificity for the endothelin-receptor subtype A, including sitaxsentan and ambrisentan, are currently undergoing investigation. This article reviews PAH associated with systemic rheumatic diseases and describes the role of ERAs in this setting. PMID:16932638

    ABSTRACT Chylopericardium is a rare disorder that may be primary (idiopathic) or secondary to injury of the thoracic duct or thymus gland. Pediatric cardiac operations are more commonly related to this complication because thymus gland is very active in this population and atrophies in the adult patients. We present a case of chylopericardium after mitral valve repair for rheumatic disease, due to thymus gland tributaries injury. PMID:24783919

    Introduction Rheumatic heart disease is the most common cause of valvular heart disease throughout the world. Echocardiography is the dominant imaging investigation in the assessment of cardiac valvular disease and the role of Magnetic Resonance Imaging (MRI) is so far limited. However, due to rapid improvements in the cardiac MRI technology in past few years, this non invasive technique is gaining interest in the examination of cardiac valves. Aim Our study was undertaken to define the role of MRI in the evaluation of Rheumatic valvular heart disease and to compare the role of MRI with transthoracic echocardiography with regard to quantity of stenosis and volume regurgitation. Materials and Methods ECG gated Cardiac MRI was performed with a 1.5-Tesla system (MAGNETOM SYMPHONY- Model 2005) using basic cardiac software (Argus viewer) by a phased-array multicoil on 50 subjects who were known cases of Rheumatic valvular heart disease. A chest radiograph and echocardiography were done in all patients before MR examination. Informed consent was taken from all patients. Results Mitral stenosis either as an isolated valvular abnormality or in combination with other valvular abnormalities constituted the major bulk of Rheumatic valvular heart disease in our study population. The average ejection fraction by ECHO is 64.94±7.11 and by MRI 67.52±7.84. The average mitral valve area by ECHO is 1.79±0.43 cm2 and by MRI 1.82±0.47 cm2. The average aortic valve area by ECHO is 1.10±0.21 cm2 and by MRI 1.12±0.25 cm2. The Coefficient of Correlation (r) is 0.82 for ejection fraction, 0.98 for mitral valve area and 0.92 for aortic valve area which means a strong positive association between the results by ECHO and MRI. In all instances, the p-value is <0.00001, suggesting that the test is highly significant. Conclusion In our study echocardiography was found to be the gold standard for the diagnosis of Rheumatic valvular heart disease and the role of MRI remained only

    The treatment of rheumatic and autoimmune skin disease in women who are pregnant or of childbearing potential can present challenges to the dermatologist. We discuss the current approaches to treating lupus erythematosus, antiphospholipid antibody syndrome, dermatomyositis, morphea and systemic sclerosis, mixed connective tissue disease, rheumatoid arthritis, and autoimmune blistering disease in such patients. In the appropriate setting, topical and systemic corticosteroids, hydroxychloroquine, dapsone, azathioprine, and ultraviolet B phototherapy may be safely and cautiously used during pregnancy. Considerations about contraception, planned conception, therapeutic options, and disease control are paramount in optimizing pregnancy outcomes and minimizing risks to both mother and fetus.

    The infections very often complicate the course of autoimmune rheumatic diseases. In diagnostic of septic complications in rheumatic patients the new biomarkers of infections can have a decisive importance. The procalciotonine test is one of them. The issue was to evaluate the diagnostic informativity of this test. The sample included 93 patients. The examination was applied to 65 patients with rheumatic diseases. Among them, 13 patients had bacterial infections. The group consisted of 33 patients with rheumatoid arthritis, 11 patients with systemic lupus erythematous, 6 patients with systemic angiitis, and 15 patients with other rheumatic diseases. The comparative group included 27 patients of cardio-therapeutic profile and 8 of these patients had bacterial infections. The procalcitonine test was applied with quantitative electrochemiluminescent technique. In patients with rheumatoid arthritis the mean levels of procalciotonine test consisted 0.10 +/- 0.13 ng/ml; with systemic lupus erythematous--0.08 +/- 0.06 ng/ml; with systemic angiitis--0.22 +/- 0.2 ng/ml; with other rheumatic diseases--0.12 +/- 0.15 ng/ml; of cardio-therapeutic profile without infections--0.08 +/- 0.06 ng/vl/ With threshold of procalcitonine test higher than 0.5/ml the sensitivity to diagnostic of infections consisted of 58%, specificity--94% in the group with rheumatic diseases. The procalciotonine test in case of no infection process with values higher than 0.5 ng/ml was detected in three patients. The evaluation of dependence of sensitivity and specificity for procalciotonine test and C-reactive protein the area under curve of procalcitonine test was larger in patients with rheumatic diseases (0.85 against 0.79) and in patients of cardio-therapeutic profile (0.92 against 0.90). The quantitative procalcitonine test is the best technique to detect septic complications in rheumatic patients. PMID:23807991

    It is well known that the steroid hormone glucocorticoid and its nuclear receptor regulate the inflammatory process, a crucial component in the pathophysiological process related to human diseases that include atherosclerosis, obesity and type II diabetes, inflammatory bowel disease, Alzheimer’s disease, multiple sclerosis, and liver tumors. Growing evidence demonstrates that orphan and adopted orphan nuclear receptors, such as peroxisome proliferator-activated receptors, liver × receptors, the farnesoid × receptor, NR4As, retinoid × receptors, and the pregnane × receptor, regulate the inflammatory and metabolic profiles in a ligand-dependent or -independent manner in human and animal models. This review summarizes the regulatory roles of these nuclear receptors in the inflammatory process and the underlying mechanisms. PMID:18375823

    2014-01-01

    Changes in vitamin D serum levels have been associated with inflammatory diseases, such as inflammatory bowel disease (IBD), rheumatoid arthritis, systemic lupus erythematosus, multiple sclerosis (MS), atherosclerosis, or asthma. Genome- and transcriptome-wide studies indicate that vitamin D signaling modulates many inflammatory responses on several levels. This includes (i) the regulation of the expression of genes which generate pro-inflammatory mediators, such as cyclooxygenases or 5-lipoxygenase, (ii) the interference with transcription factors, such as NF-κB, which regulate the expression of inflammatory genes and (iii) the activation of signaling cascades, such as MAP kinases which mediate inflammatory responses. Vitamin D targets various tissues and cell types, a number of which belong to the immune system, such as monocytes/macrophages, dendritic cells (DCs) as well as B- and T cells, leading to individual responses of each cell type. One hallmark of these specific vitamin D effects is the cell-type specific regulation of genes involved in the regulation of inflammatory processes and the interplay between vitamin D signaling and other signaling cascades involved in inflammation. An important task in the near future will be the elucidation of the regulatory mechanisms that are involved in the regulation of inflammatory responses by vitamin D on the molecular level by the use of techniques such as chromatin immunoprecipitation (ChIP), ChIP-seq, and FAIRE-seq.

    The incidence of rheumatism and rheumatic valvulopathy in Sicily is assessed and the sites most commonly involved in the first and second attacks described. The medical aspects of te question are examined from several points of view: prophylaxis of sites, medical treatment personal and ambient hygiene, gradual defectiveness of the pump, associated diseases, etc. The concept of invalidity is viewed in terms of direct and associated anatomical damage and frank and potential invalidity (absolute or relative), the weight or assistance attributable to the family and the incidence of the local social environment in the question of finding work, etc. The basic criteria for surgery are noted. Care must be taken to preserve the few remaining structures. Mortality is still high and the incidence of heart disease is higher among rheumatic Sicilian children. Not enough is known about overcrowding, the schools attended by the poor, and the higher incidence in low-income classes. Failure to affront some of these features, determined as much by action (or its postponement) by government as by income, results in meaningless medicine, divorced from social reform and true the scientific spirit, a cover for special interests and a demonstration of profit factors wherein the commercialising relationship is increasingly evident.

    Spondyloarthritis (SpA) is a frequent extra-intestinal manifestation in patients with inflammatory bowel disease (IBD), although its real diffusion is commonly considered underestimated. Abnormalities in the microbioma and genetic predisposition have been implicated in the link between bowel and joint inflammation. Otherwise, up to date, pathogenetic mechanisms are still largely unknown and the exact influence of the bowel activity on rheumatic manifestations is not clearly explained. Due to evidence-based results of clinical studies, the interest on clinically asymptomatic SpA in IBD patients increased in the last few years. Actually, occult enthesitis and sacroiliitis are discovered in high percentages of IBD patients by different imaging techniques, mainly enthesis ultrasound (US) and sacroiliac joint X-ray examinations. Several diagnostic approaches and biomarkers have been proposed in an attempt to correctly classify and diagnose clinically occult joint manifestations and to define clusters of risk for patient screening, although definitive results are still lacking. The correct recognition of occult SpA in IBD requires an integrated multidisciplinary approach in order to identify common diagnostic and therapeutic strategies. The use of inexpensive and rapid imaging techniques, such as US and X-ray, should be routinely included in daily clinical practice and trials to correctly evaluate occult SpA, thus preventing future disability and worsening of quality of life in IBD patients.

    The major diseases associated with HLA-B27 (Reiter's disease, ankylosing spondylitis, acute anterior uveitis, and psoriatic arthritis) all occur much more commonly in men. Published evidence indicates that the antigen HLA-B27 is associated with high testosterone concentrations in men. Moreover, the antigen HLA-B44 exerts a protective effect on one of these diseases (psoriatic arthritis), and there are external grounds for supposing that HLA-B44 indexes an antiandrogenic process. These data are interpreted as support for the hypothesis (first adumbrated nearly 20 years ago) that HLA antigens index unusual hormone concentrations, which in turn are causally related to the diseases. An examination of published reports suggests that sibs of probands with ankylosing spondylitis (and perhaps Reiter's disease) contain an excess of men, and that sibs of probands with rheumatoid arthritis contain an excess of women. These data lend further support to the hypothesis. PMID:2059084

    Diversity and plasticity are two hallmarks of macrophages. M1 macrophages (classically activated macrophages) are pro-inflammatory and have a central role in host defense against infection, while M2 macrophages (alternatively activated macrophages) are associated with responses to anti-inflammatory reactions and tissue remodeling, and they represent two terminals of the full spectrum of macrophage activation. Transformation of different phenotypes of macrophages regulates the initiation, development, and cessation of inflammatory diseases. Here we reviewed the characters and functions of macrophage polarization in infection, atherosclerosis, obesity, tumor, asthma, and sepsis, and proposed that targeting macrophage polarization and skewing their phenotype to adapt to the microenvironment might hold great promise for the treatment of inflammatory diseases.

    Aims Rheumatic heart disease (RHD) accounts for over a million premature deaths annually; however, there is little contemporary information on presentation, complications, and treatment. Methods and results This prospective registry enrolled 3343 patients (median age 28 years, 66.2% female) presenting with RHD at 25 hospitals in 12 African countries, India, and Yemen between January 2010 and November 2012. The majority (63.9%) had moderate-to-severe multivalvular disease complicated by congestive heart failure (33.4%), pulmonary hypertension (28.8%), atrial fibrillation (AF) (21.8%), stroke (7.1%), infective endocarditis (4%), and major bleeding (2.7%). One-quarter of adults and 5.3% of children had decreased left ventricular (LV) systolic function; 23% of adults and 14.1% of children had dilated LVs. Fifty-five percent (n = 1761) of patients were on secondary antibiotic prophylaxis. Oral anti-coagulants were prescribed in 69.5% (n = 946) of patients with mechanical valves (n = 501), AF (n = 397), and high-risk mitral stenosis in sinus rhythm (n = 48). However, only 28.3% (n = 269) had a therapeutic international normalized ratio. Among 1825 women of childbearing age (12–51 years), only 3.6% (n = 65) were on contraception. The utilization of valvuloplasty and valve surgery was higher in upper-middle compared with lower-income countries. Conclusion Rheumatic heart disease patients were young, predominantly female, and had high prevalence of major cardiovascular complications. There is suboptimal utilization of secondary antibiotic prophylaxis, oral anti-coagulation, and contraception, and variations in the use of percutaneous and surgical interventions by country income level.

    Autoimmune rheumatic diseases (ARD) affect mainly young women during their reproductive years. Fertility is usually not diminished but the time it takes to conceive is usually longer. Factors related to an ARD or to its treatment are responsible for this effect. In addition, contraception counseling is required to prevent negative fetal outcome and exacerbation of disease symptoms. In recent years, advances in therapies, clarification of risk factors for adverse pregnancy outcomes, and a multidisciplinary approach have vastly improved obstetric management, increasing the possibility of successful pregnancy with a high likelihood of favorable outcome.

    Objective To examine the temporal and dose-related effect of glucocorticoids (GCs) on body mass index (BMI) in children with rheumatic diseases. Methods Children initiating GCs for a rheumatic disease (n=130) were assessed every 3 months for 18 months. BMI, weight and height Z-score trajectories were described according to GC starting dosage in prednisone equivalents: high (≥1.0 mg/kg/day), low (<0.2 mg/kg/day to a maximum of 7.5 mg/d), and moderate (between high and low) dosage. The impact of GC dosing, underlying diagnosis, pubertal status, physical and disease activity on BMI Z-scores and on percent body fat was assessed with longitudinal mixed effects growth curve models. Results The GC starting dose was high in 59% and moderate in 39% of patients. The peak BMI Z score was +1.29 at 4 months with high-dose GCs and +0.69 at 4.2 months with moderate-dose GCs (p<0.001). Overall, 50% (95% confidence interval 41–59%) of children returned to within +0.25 standard deviations (SD) of their baseline BMI Z score. Oral GC dose over the preceding 3 months was the most significant determinant of BMI Z-score and percent body fat. The proportion of days in receipt of GCs, disease activity, and a diagnosis of systemic-onset juvenile idiopathic arthritis were also associated with BMI Z scores. The correlation between changes in BMI and changes in percent body fat was 0.09. Conclusions In children with rheumatic disease starting moderate and high doses of GCs, BMI Z score peaked at 4 months and only half returned to within +0.25 SD of their baseline BMI Z-score by 18 months.

    Previous work has shown that leucocyte adhesiveness/aggregation (LAA), as measured by the leukergy test, correlates well with disease severity in rheumatic patients. As LAA is probably a manifestation of the acute phase reaction various components of the acute phase reaction were measured in order to identify the best marker of disease activity. In addition to LAA, the following variables were measured in 79 patients with various rheumatic diseases and in 10 controls: white blood cell and platelet counts, erythrocyte sedimentation rate, haptoglobin, fibrinogen, C reactive protein, albumin, globulin, caeruloplasmin, alpha 1, alpha 2, beta, and gamma globulin, and haemoglobin concentrations. Patients were graded according to the state of their disease as mild, moderate, or severe. The extent of leucocyte adhesiveness/aggregation in peripheral blood proved to be the best laboratory variable for the grading of disease activity. Correct grading was obtained in 63% of the patients by means of the LAA, compared with 48% with C reactive protein, 41% with caeruloplasmin, 40% with haptoglobin, and 32% with haemoglobin. It is suggested that LAA of the peripheral blood during inflammation may be used as a reliable marker of disease severity. PMID:3260093

    Patients with rheumatic diseases can present with movement and other neurodegenerative disorders. It may be underappreciated that movement and other neurodegenerative disorders can encompass a wide variety of disease entities. Such disorders are strikingly heterogeneous and lead to a wider spectrum of clinical injury than seen in Parkinson's disease. Therefore, we sought to stringently phenotype movement and other neurodegenerative disorders presenting in a case series of rheumatic disease patients. We integrated our findings with a review of the literature to understand mechanisms which may account for such a ubiquitous pattern of clinical injury.Seven rheumatic disease patients (5 Sjögren's syndrome patients, 2 undifferentiated connective tissue disease patients) were referred and could be misdiagnosed as having Parkinson's disease. However, all of these patients were ultimately diagnosed as having other movement or neurodegenerative disorders. Findings inconsistent with and more expansive than Parkinson's disease included cerebellar degeneration, dystonia with an alien-limb phenomenon, and nonfluent aphasias.A notable finding was that individual patients could be affected by cooccurring movement and other neurodegenerative disorders, each of which could be exceptionally rare (ie, prevalence of ∼1:1000), and therefore with the collective probability that such disorders were merely coincidental and causally unrelated being as low as ∼1-per-billion. Whereas our review of the literature revealed that ubiquitous patterns of clinical injury were frequently associated with magnetic resonance imaging (MRI) findings suggestive of a widespread vasculopathy, our patients did not have such neuroimaging findings. Instead, our patients could have syndromes which phenotypically resembled paraneoplastic and other inflammatory disorders which are known to be associated with antineuronal antibodies. We similarly identified immune-mediated and inflammatory markers of injury

    The use of biomarkers is becoming increasingly intrinsic to the practice of medicine and holds great promise for transforming the practice of rheumatology. Biomarkers have the potential to aid clinical diagnosis when symptoms are present or to provide a means of detecting early signs of disease when they are not. Some biomarkers can serve as early surrogates of eventual clinical outcomes or guide therapeutic decision making by enabling identification of individuals likely to respond to a specific therapy. Using biomarkers might reduce the costs of drug development by enabling individuals most likely to respond to be enrolled in clinical trials, thereby minimizing the number of participants required. In this Review, we discuss the current use and the potential of biomarkers in rheumatology and in select fields at the forefront of biomarker research. We emphasize the value of different types of biomarkers, addressing the concept of ‘actionable’ biomarkers, which can be used to guide clinical decision making, and ‘mechanistic’ biomarkers, a subtype of actionable biomarker that is embedded in disease pathogenesis and, therefore, represents a superior biomarker. We provide examples of actionable and mechanistic biomarkers currently available, and discuss how development of such biomarkers could revolutionize clinical practice and drug development.

    2009-10-01

    Osteoarthritis and rheumatoid arthritis are rheumatic diseases for which a curative treatment does not currently exist. Their management is directed towards pain relief achieved with different classes of drugs among which non-steroidal and steroidal anti-inflammatory substances are the most frequently used agents. Nevertheless, the oral or systemic administration of such drugs is hindered by numerous side effects, which could be overcome by their intra-articular (i-a.) administration as dosage forms capable of gradually releasing the active substance. The present review article summarises the research done in the field of drug delivery systems for i-a. injection vs. current management of osteoarthritis or rheumatoid arthritis. Aspects such as the influence of size, shape, polymer matrix or targeted drug on the i-a. retention time, phagocytosis and biological activity will be discussed. Finally, we will comment on the need for adapted delivery systems for the novel and very potent anti-inflammatory drugs, such as inhibitors of the p38 mitogen-activated protein kinase or the IL-1beta conversion enzyme, which to date cannot be properly used due to the severe side effects associated with their systemic administration.

    This study was undertaken to determine the prevalence of LE cells in synovial fluid and their importance for the diagnosis of rheumatic disease. Synovial fluid was obtained from 631 patients: 31 with systemic lupus erythematosus (SLE), 337 with rheumatoid arthritis (RA), 4 with Still's disease, 9 with systemic scleroderma (SS), 27 with the overlap syndrome (RA/SLE), 132 with ankylosing spondylitis (AS), 57 with Reiter's syndrome, and 34 with psoriatic arthritis (PA). The fluid was centrifuged, precipitate smears were done and were May-Grünwald-Giemsa stained for cytologic assessment. The supernatant was collected for antinuclear antibody (ANA) testing. Physicochemical and serologic properties of the synovial fluid were routinely determined. All synovial fluids demonstrated signs of inflammation. The presence of LE cells was ascertained in five patients with SLE and nine patients with the overlap syndrome. In these cases, LE cells were accompanied by ANA. In addition, hematoxylin bodies were revealed in SLE patients. LE cells were observed in 2.6% of patients with RA but were not accompanied by ANA. Patients with SS, Still's disease, AS, Reiter's syndrome, and PA tested negative for LE cells. It appears from these results that LE cells are rarely present in the synovial fluid of patients with rheumatic diseases. In contrast, they occur in more than 40% of patients with the overlap syndrome and may thus be regarded as important for the diagnosis of this condition. PMID:21365954

    2015-07-01

    Despite being preventable, rheumatic heart disease (RHD) remains a significant global cause of cardiovascular disease. Echocardiographic screening for early detection of RHD has the potential to enable timely commencement of treatment (secondary prophylaxis) to halt progression to severe valvular disease. However, a number of issues remain to be addressed regarding its feasibility. The natural history of Definite RHD without a prior history of acute rheumatic fever (ARF) and Borderline RHD are both unclear. Even if they are variants of RHD it is not known whether secondary antibiotic prophylaxis will prevent disease progression as it does in "traditionally" diagnosed RHD. False positives can also have a detrimental impact on individuals and their families as well as place substantial burdens on health care systems. Recent research suggests that handheld echocardiography (HAND) may offer a cheaper and more convenient alternative to standard portable echocardiography (STAND) in RHD screening. However, while HAND is sensitive for the detection of Definite RHD, it is less sensitive for Borderline RHD and is relatively poor at detecting mitral stenosis (MS). Given its attendant limited specificity, potential cases detected with HAND would require re-examination by standard echocardiography. For now, echocardiographic screening for RHD should remain a subject of research rather than routine health care. PMID:26835376

    New therapeutic principles and considerable diagnostic advances have made it possible to define different rheumatic diseases and especially rheumatoid arthritis (RA) at an early stage and by starting an early and aggressive medication a considerable proportion of patients with RA will reach the status of low disease activity or even remission. With the additional development of composite measures to estimate the disease activity of RA, it was the goal of an international working group consisting of rheumatologists and patients to develop recommendations for treating rheumatoid arthritis in a similar way as for patients with hypertension or diabetes, with the aim to achieve remission as often as possible. This treat-to-target initiative has taken off in quite a number of different countries including Germany leading to discussions on how this initiative can be integrated into the specific national healthcare systems and what possibilities would exist for its implementation. To develop strategies for an improved healthcare of people suffering from rheumatic diseases and using RA as an example, action elements and postulates were developed which will be discussed in more detail in the present manuscript.

    Dysregulated bone remodeling occurs when there is an imbalance between bone resorption and bone formation. In rheumatic diseases, including rheumatoid arthritis (RA) and seronegative spondyloarthritis, systemic and local factors disrupt the process of physiologic bone remodeling. Depending upon the local microenvironment, cell types, and local mechanical forces, inflammation results in very different effects on bone, promoting bone loss in the joints and in periarticular and systemic bone in RA and driving bone formation at enthesial and periosteal sites in diseases such as ankylosing spondylitis (AS), included within the classification of axial spondyloarthritis. There has been a great deal of interest in the role of osteoclasts in these processes and much has been learned over the past decade about osteoclast differentiation and function. It is now appreciated that osteoblast-mediated bone formation is also inhibited in the RA joint, limiting the repair of erosions. In contrast, osteoblasts function to produce new bone in AS. The Wnt and BMP signaling pathways have emerged as critical in the regulation of osteoblast function and the outcome for bone in rheumatic diseases, and these pathways have been implicated in both bone loss in RA and bone formation in AS. These pathways provide potential novel approaches for therapeutic intervention in diseases in which inflammation impacts bone. PMID:26411424

    Summary Rheumatic heart disease (RHD) is characterized by the presence of anti-streptococcal group A antibodies and anti-endothelial cell antibodies (AECA). Molecular mimicry between streptococcal antigens and self proteins is a hallmark of the pathogenesis of rheumatic fever. We aimed to identify, in RHD patients, autoantibodies specific to endothelial autoantigens cross-reactive with streptococcal proteins and to evaluate their role in inducing endothelial damage. We used an immunoproteomic approach with endothelial cell-surface membrane proteins in order to identify autoantigens recognized by AECA of 140 RHD patients. Cross-reactivity of purified antibodies with streptococcal proteins was analysed. Homologous peptides recognized by serum cross-reactive antibodies were found through comparing the amino acid sequence of streptococcal antigens with human antigens. To investigate interleukin (IL)-1R-associated kinase (IRAK1) and nuclear factor-κB (NF-κB) activation, we performed a Western blot analysis of whole extracts proteins from unstimulated or stimulated human microvascular cardiac endothelial cells (HMVEC-C). Adhesion molecule expression and release of proinflammatory cytokines and growth factors were studied by multiplex bead based immunoassay kits. We observed anti-vimentin antibodies in sera from 49% RHD AECA-positive patients. Cross-reactivity of purified anti-vimentin antibodies with heat shock protein (HSP)70 and streptopain streptococcal proteins was shown. Comparing the amino acid sequence of streptococcal HSP70 and streptopain with human vimentin, we found two homologous peptides recognized by serum cross-reactive antibodies. These antibodies were able to stimulate HMVEC-C inducing IRAK and NF-κB activation, adhesion molecule expression and release of proinflammatory cytokines and growth factors.

    Purpose of review To review recent developments in our understanding of endoplasmic reticulum (ER) aminopeptidase-1 (ERAP1) function in relation to its role in MHC class I peptide presentation and HLA class I-associated diseases. Recent findings ERAP1 polymorphisms exhibiting loss-of-function have been associated with protection from ankylosing spondylitis (AS). The aminopeptidase function of ERAP1 optimizes peptides for binding and presentation by MHC class I. Most studies have revealed reduced MHC class I expression in situations of reduced ERAP1 function. Under these circumstances the presented peptides are often N-terminally extended, and cell surface complexes are unstable and fall apart more readily. In contrast, peptides presented by HLA-B*27:05 when ERAP1 is silenced are frequently extended on the C-terminus. Recent work has emphasized the importance of assessing the function of allotypes encoded by ERAP1 haplotypes, rather than effects of single amino acid substitutions. The allotypes found in a series of AS patients were poorer at restoring HLA-B27 expression than allotypes found in unaffected controls, which may seem contrary to the genetic data linking loss-of-function to protection. Summary More work is needed to understand how ERAP1 variants associated with risk and protection influence the quality and quantity of peptides available for binding to HLA class I molecules in the ER. Moreover, we need to determine allele-specific effects of ERAP1 variants in the context of HLA-B*51 and HLA-Cw*6, which are associated with Behçet’s disease and psoriasis, respectively.

    Variables influencing total direct medical costs in inflammatory bowel diseases include country, diagnosis (generally, patients with Crohn's disease generated higher costs compared with patients with ulcerative colitis), and year since diagnosis. In all studies the mean costs were higher than the median costs, which indicates that a relatively small group of the most severely ill patients significantly affect the total cost of treatment of these diseases. A major component of direct medical costs was attributed to hospitalisation, ranging from 49% to 80% of the total. The costs of surgery constituted 40–61% of inpatient costs. Indirect costs in inflammatory bowel diseases, unappreciated and often underestimated (considered by few authors and as a loss of work), are in fact important and may even exceed direct medical costs.

    Background: Rheumatic diseases involve multiple organs that are affected by immunological mechanisms. Treatment with corticosteroids and immunosuppressive agents may also increase the frequency of infection. Cytomegalovirus (CMV) is a widespread herpes virus and a well-recognized pathogen, which causes an opportunistic and potentially fatal infection in immunocompromised patients. This retrospective study aimed to investigate the clinical and laboratory characteristics of CMV pneumonia in patients with rheumatic diseases after immunosuppressive therapy in a single center in Shanghai, China. Methods: Eight hundred and thirty-four patients with rheumatic diseases who had undergone CMV-DNA viral load tests were included, and the medical records of 142 patients who were positive for CMV-DNA in plasma samples were evaluated. GraphPad Prism version 5.013 (San Diego, CA, USA) was used to conduct statistical analysis. The correlation between CMV-DNA viral loads and lymphocyte counts was assessed using the Spearman rank correlation coefficient test. Significance between qualitative data was analyzed using Pearson's Chi-squared test. The cut-off thresholds for CMV-DNA viral load and lymphocyte count were determined by receiver operating characteristic (ROC) curve analysis. Results: One hundred and forty-two patients had positive CMV viral load tests. Of these 142 patients, 73 patients with CMV pneumonia were regarded as symptomatic, and the other 69 were asymptomatic. The symptomatic group received higher doses of prednisolone (PSL) and more frequently immunosuppressants than the asymptomatic group (P < 0.01). The symptomatic group had lower lymphocyte counts, especially CD4+ T-cells, than the asymptomatic group (P < 0.01). By ROC curve analysis, when CD4+ T-cell count was <0.39 × 109/L, patients with rheumatic diseases were at high risk for symptomatic CMV infection. The CMV-DNA load was significantly higher in the symptomatic patients than that in asymptomatic patients (P

    The Inflammatory Bowel Disease Competence Network is a network of more than 500 physicians and scientists from university clinics, hospitals and gastroenterology practices. The focus extends from the two major forms of inflammatory bowel diseases, Crohn's disease and ulcerative colitis, into other chronic inflammatory conditions affecting the intestine, including coeliac disease and microscopic colitis. The network translates basic science discoveries (in particular in the molecular epidemiology research) into innovative diagnostics and therapy. Through its strong networking structures it supports a continuous process to improve quality and standardisation in patient care that is implemented in close interaction with European networks addressing this disease group.Optimisation of patient care based on scientifically proven evidence is a main focus of the network. Therefore, it supports and coordinates translational research and infrastructure projects that investigate aetiology, improvement of diagnostic methods, and development of new or improved use of established therapies. Members participate in various training projects, thus ensuring the rapid transfer of research results into clinical practice.The competence network cooperates with the main patient organisations to engage patients in all levels of activities. The network and the patient organisations have interest in promoting public awareness about the disease entities, because their importance and burden is underestimated in non-specialised medical fields and among the general public.

    Fatigue is a symptom of arthritis that causes difficulty at work. An improved understanding of this symptom could assist its management in the work environment. The aim of this study was to explore people with rheumatic diseases' experiences of fatigue in work. A qualitative descriptive design was used with semi-structured interviews and a constant comparative method of data analysis. There were 18 participants, the majority of them female with Rheumatoid Arthritis (RA) and working full-time. Three themes were identified: "Impact of fatigue on work performance" with cognition, mood and physical abilities being the main difficulties reported. In the second theme "Disclosure at Work" participants discussed disclosing their disease to employers but reported a lack of understanding of fatigue from colleagues. The final theme "work-based fatigue management strategies" included cognitive strategies and energy management techniques, which were mainly self-taught. In this study, fatigue was reported to impact on many areas of work performance with limited understanding from colleagues and employers. Interventions from health professionals to assist with development of work-related self-management skills are required to assist with symptom management in the work place. Such interventions should include education to employers and colleagues on the nature of fatigue in Rheumatic diseases. PMID:26516896

    Rheumatic heart disease continues to contribute greatly to the burden of cardiovascular disease in Sub-saharan Africa despite advances in medical care. Evidence suggests that the prevalence is far greater than reported. There is therefore the need to emphasize routine screening for at-risk subjects and to appropriately institute adequate therapy and other preventive measures to avert the late and awry manifestation of the disease as presented in this case. This is a case report of one of numerous cases that may eventually suffer the same fate if urgent preventive measures are not instituted. A 20-year old Nigerian woman with past history of recurrent sore throat and a 10-year history of recurrent easy fatiguability and markedly dilated left atrium and pulmonary hypertension presented when she developed severe pulmonary hypertension. A concerted action at all levels of prevention is needed to reduce the burden of this disease among the young population in developing countries. PMID:21532731

    The ingest of diets with high content of fats and carbohydrates, low or no physical exercise and a stressful routine are part of the everyday lifestyle of most people in the western world. These conditions are triggers for different diseases with complex interactions between the host genetics, the metabolism, the immune system and the microbiota, including inflammatory bowel diseases (IBD), obesity and diabetes. The incidence of these disorders is growing worldwide; therefore, new strategies for its study are needed. Nowadays, the majority of researches are in use of murine models for understand the genetics, physiopathology and interaction between cells and signaling pathways to find therapeutic solutions to these diseases. The zebrafish, a little tropical water fish, shares 70% of our genes and conserves anatomic and physiological characteristics, as well as metabolical pathways, with mammals, and is rising as a new complementary model for the study of metabolic and inflammatory diseases. Its high fecundity, fast development, transparency, versatility and low cost of maintenance makes the zebrafish an interesting option for new researches. In this review, we offer a discussion of the existing genetic and induced zebrafish models of two important Western diseases that have a strong inflammatory component, the IBD and the obesity.

    To assess the frequency of hospital encoded diagnoses of acute rheumatic fever (ARF) and Kawasaki disease (KD), the two leading causes of acquired heart disease in children in the United States, we performed a survey of the medical record departments of United States children's hospitals and of general hospitals that have at least 400 beds and a pediatric ward. With a simple questionnaire, data were gathered for the years 1984 through 1990 by ICD.9CM codes, with a 58% response rate. About 8000 diagnoses of KD and 6000 diagnoses of ARF were encoded during the study period. Encoded diagnoses of both KD and ARF showed yearly fluctuations in the earlier years (1984 through 1987). For KD there was a general trend toward increasing numbers after 1986. These data are consistent with increased physician awareness and diagnosis of KD. For ARF a gradual decline was observed between 1986 and 1990. About 80% of ARF diagnoses were reported from general hospitals. The much smaller pool of encoded diagnoses of ARF at the children's hospitals showed a 56% increase from 1985 to 1986. These data suggest that the highly publicized increase in cases of acute rheumatic fever in the United States during the mid-1980s may reflect focal rather than nationwide increased activity and that nationally the number of diagnoses of ARF actually may have continued to decline gradually from 1984 through 1990.

    Rheumatic heart disease (RHD) makes a heavy burden in human lives and economy. The proteomic analysis of acute rheumatic heart disease (ARHD) can provide precious data to study RHD at the early stages, but no one has looked into. So based on our early research we applied the method of continuous GAS stimulation on Lewis rats to duplicate the animal model of ARHD. And the mitral valves of rats in control group (n=10) and ARHD group (n=10) were selected for proteomic analysis of ARHD with the iTRAQ labeling based 2D LC-ESI-MS/MS quantitative technology. We identified 3931 proteins in valve tissue out of which we obtained 395 differentially expressed proteins containing 176 up-regulated proteins and 119 down-regulated proteins. Changes in levels of GAPDH (6.793 times higher than the control group) and CD9 (2.63 times higher than the control group) were confirmed by Western blot or immunohistochemistry. The differentially expressed proteins such as GAPDH, CD9, myosin, collagen and RAC1 may be potential biomarkers for ARHD. Moreover, the mitral valve protein profile shed light on further understanding and investigating ARHD. PMID:26823728

    Objective To examine the extent to which arthritis intruded upon 4 social roles (spouse, homemaker, parent, worker). In accordance with propositions set forth by social identity theory and the identity-relevant stress hypothesis, we hypothesized that 1) illness intrusion would predict psychological well-being and 2) role importance would moderate the relationship between illness intrusion and psychological adjustment, such that intrusion into highly valued roles would be the most psychologically distressing. Methods Participants were recruited from the practices of rheumatologists affiliated with a major urban hospital. A total of 113 individuals (73% women) with diagnosed rheumatic disease completed a mailed questionnaire. Results For all 4 roles, illness intrusion was related to decreased psychological well-being. In the worker and parent roles, the effects of illness intrusion on adjustment were moderated by whether respondents valued these particular roles. For example, psychological well-being was lowest among those individuals whose illness intruded greatly upon work and who highly valued their worker role identity. Conclusion The findings highlight the advantages of assessing both domain-specific illness intrusion and role importance in predicting psychological well-being among persons with rheumatic diseases. Importantly, results also demonstrate the utility of applying a social identity framework in understanding adjustment processes among persons with chronic illness. PMID:16583409

    2005-01-01

    Drug therapy plays a major role in the management of many rheumatic diseases and is particularly important in rheumatoid arthritis (RA) because of the significant rates of morbidity and mortality (Pincus, 1995). Understanding of the pathogenesis of RA has led to the development of new and more effective drugs (Emery et al., 1999), but the ultimate efficacy of any drug therapy depends upon the patient's decision to take it. There is widespread agreement that many people with rheumatic disease do not adhere to their medication regimens (Deyo et al., 1981; Belcon et al., 1984; Pullar et al., 1988; Hill et al., 2001). Research has demonstrated that 50% of women taking hormone replacement therapy for the prevention of osteoporosis discontinue treatment after a year (Fordham, 2000) and similar rates of discontinuation are found in other chronic diseases (Haynes et al., 1996, 2000). This is bewildering as, in asymptomatic illnesses such as hypertension and diabetes, the expectation is that levels of adherence would be lower than in diseases where pain and stiffness are present. The picture becomes even more confusing when we consider the findings from a recent multi-country study of RA, which found no association between adherence and disease severity, nor with the treatment prescribed (Viller et al., 1999). In chronic disease poor adherence is commonplace. The World Health Organization (WHO) recognizes this and has recently stated that 'poor adherence to treatment of chronic diseases is a worldwide problem of striking magnitude' and cites adherence to long-term therapy for chronic illnesses in developed countries averaging just 50% (WHO, 2003). The first part of this two part review focuses on adherence with drug therapy, and the second part discusses different methods of measuring it. PMID:17041995

    Pregnancy in women with rheumatic disorders is known to be associated with risks for both the mother and fetus; however, these risks can be minimized with proper planning and careful management of the disease. In the Middle East, there are specific cultural challenges that may have a negative impact on the care that women with rheumatic disorders receive. There is a need for cross-collaboration between specialist physicians, improved awareness of rheumatic disorders among the general public and more open discussion with patients about the potential complications of pregnancy. Women in the region are often unwilling to discuss their disease with their partner and are even less likely to seek advice regarding family planning from their physician. The objective of this review is to highlight the specific challenges of pregnancy management and to discuss why establishing specialist pregnancy clinics for women with rheumatic disorders could be an effective solution. Such clinics can provide high quality care before, during and after pregnancy as shown in several European and US centers. Additionally, such clinics could be useful for the collection of pregnancy outcomes data from the Middle East, which may currently be lacking in the region, in order to highlight where further improvements can be made. With specialist care and analysis of pregnancy outcomes, the standard of care for women with rheumatic disorders in this area could be significantly improved. PMID:26304021

Although there is a general lack of rigorous scientific evidence that demonstrates which diet is best for certain patients, several diets—such as the low-fermentable oligosaccharide, disaccharide, monosaccharide, and polyol diet; the specific carbohydrate diet; the anti-inflammatory diet; and the Paleolithic diet—have become popular. This article discusses the diets commonly recommended to IBD patients and reviews the supporting data. PMID:27118948

    Objectives Hypertrophic and exudative synovitis of the knee is one of the earliest symptoms in rheumatic diseases. In the case of pharmacotherapy failure, other methods which directly remove the inflamed synovial membrane are used – synovectomies. Radiosynovectomy (RSV) is the radiopharmaceutical application of colloidal solution to joint cavities. In this study, the authors assessed the efficacy of knee radiosynovectomy with yttrium-90 (Y-90) in several groups of patients divided into certain rheumatic diseases. Material and methods The study group consisted of 70 patients aged from 29 to 65 years with hypertrophic and exudative synovitis of the knee in rheumatic diseases such as rheumatoid arthritis, osteoarthrosis and spondyloarthropathies. Radiopharmaceutical colloid of Y-90, with a radiation dose of 185-222 MBq in a volume of 2-3 ml, was administered to joint. Then the knee joint was immobilized for 72 h. During visits V1, V2, V3 and V4, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were measured and ultrasound of the knee was performed. Disease activity was evaluated by the WOMAC scale, HAQ and 100-mm visual analog scale (VAS). Results The most significant difference of synovial hypertrophy, before and after the procedure, was obtained in patients with rheumatoid arthritis. Variability of effusion before and after the procedure in all groups was comparable and statistically significant. The greatest improvement in variability of inflammatory parameters, before and 4 weeks after radiosynovectomy, was observed in patients with rheumatoid arthritis. Conclusions In the therapeutic algorithm radiosynovectomy should be located between conservative treatment and operative procedures. Radiosynovectomy does not require hospitalization or prolonged rehabilitation. Radiosynoviorthesis affects the patient's general condition, which is associated with eliminating pain and restoring joint function. PMID:27407269

    2015-01-01

    Purpose of review This article will review the genetic evidence implicating ERAP1, which encodes the endoplasmic reticulum-associated amino-peptidase 1, in susceptibility to rheumatic disease. Recent findings Genetic variants and haplotypes of ERAP1 are associated with ankylosing spondylitis, psoriasis, and Behçet’s disease in people of varying ancestries. In each of these diseases, disease-associated variants of ERAP1 have been shown to interact with disease-associated class I Human Leukocyte Antigen (HLA) alleles to influence disease risk. Functionally, disease-associated missense variants of ERAP1 concertedly alter ERAP1 enzymatic function, both quantitatively and qualitatively, while other disease-associated variants influence ERAP1 expression. Therefore, ERAP1 haplotypes (or allotypes) should be examined as functional units. Biologically, this amounts to an examination of the gene regulation and function of the protein encoded by each allotype. Genetically, the relationship between disease risk and ERAP1 allotypes should be examined to determine whether allotypes or individual variants produce the most parsimonious risk models. Summary Future investigations of ERAP1 should focus on comprehensively characterizing naturally-occurring ERAP1 allotypes, examining the enzymatic function and gene expression of each allotype, and identifying specific allotypes that influence disease susceptibility.

    Pain is a complex phenomenon influenced by a number of biological, psychological, and social factors. The treatment of pain is most effective when using a multidisciplinary approach consisting of a careful selection of pharmacologic and non-pharmacologic interventions based upon disease factors, pain characteristics, psychological coping abilities and lifestyle factors. In this review we focus on research-based evidence for non-pharmacologic interventions including psychological interventions, physical exercise, patient education, and complementary approaches for pain management in patients with rheumatic diseases and common musculoskeletal pain conditions, such as low back pain. The vast proportion of research studies is on adults with chronically painful conditions but pediatric studies are also reviewed wherever possible to give the reader a more inclusive view of non-pharmacological approaches for pain management across the lifespan.

    Rheumatic heart disease (RHD) remains highly prevalent in resource-constrained settings around the world, including countries with high rates of HIV/AIDS. Although both are immune-mediated diseases, it is unknown whether HIV modifies the risk or progression of RHD. We performed screening echocardiography to determine the prevalence of latent RHD in 488 HIV-infected children aged 5-18 in Kampala, Uganda. The overall prevalence of borderline/definite RHD was 0.82% (95% confidence interval: 0.26% to 2.23%), which is lower than the published prevalence rates of 1.5%-4% among Ugandan children. There may be protective factors that decrease the risk of RHD in HIV-infected children. PMID:26413847

    Objectives Rheumatic heart disease (RHD) remains the leading acquired heart disease in the young worldwide. We aimed at assessing outcomes and influencing factors in the contemporary era. Methods Hospital-based cohort in a high-income island nation where RHD remains endemic and the population is captive. All patients admitted with newly diagnosed RHD according to World Heart Federation echocardiographic criteria were enrolled (2005–2013). The incidence of major cardiovascular events (MACEs) including heart failure, peripheral embolism, stroke, heart valve intervention and cardiovascular death was calculated, and their determinants identified. Results Of the 396 patients, 43.9% were male with median age 18 years (IQR 10–40)). 127 (32.1%) patients presented with mild, 131 (33.1%) with moderate and 138 (34.8%) with severe heart valve disease. 205 (51.8%) had features of acute rheumatic fever. 106 (26.8%) presented with at least one MACE. Among the remaining 290 patients, after a median follow-up period of 4.08 (95% CI 1.84 to 6.84) years, 7 patients (2.4%) died and 62 (21.4%) had a first MACE. The annual incidence of first MACE and of heart failure were 59.05‰ (95% CI 44.35 to 73.75) and 29.06‰ (95% CI 19.29 to 38.82), respectively. The severity of RHD at diagnosis (moderate vs mild HR 3.39 (0.95 to 12.12); severe vs mild RHD HR 10.81 (3.11 to 37.62), p<0.001) and ongoing secondary prophylaxis at follow-up (HR 0.27 (0.12 to 0.63), p=0.01) were the two most influential factors associated with MACE. Conclusions Newly diagnosed RHD is associated with poor outcomes, mainly in patients with moderate or severe valve disease and no secondary prophylaxis. PMID:26537732

    We aimed to determine the prevalence of hypovitaminosis D in patients with autoimmune rheumatic diseases (ARDs) in China and its association with demographic characteristics of the patients. We recruited 384 patients in this cross-sectional study including 121 cases of systemic lupus erythematosus (SLE), 131 rheumatoid arthritis (RA), 102 spondyloarthritis (SpA) and 30 other ARDs. For each patient, demographic information was collected and serum concentration of 25OHD3 was measured by electrochemiluminescence immunoassay (ECLIA). The multivariate logistic regression model was used to investigate the association between vitamin D deficiency and patient characteristics. The mean serum vitamin D level of the 384 patients was 18.91 (8.12) ng/mL, and the median age was 37.33 (12.01) yrs. Among these patients, 222 (57.81%) and 127 (33.07%) were found to be vitamin D deficiency and insufficiency, respectively. From the disease perspective, the percentages of insufficiency and deficiency were as follow: 97.52% and 84.30% in SLE, 87.02% and 48.85% in RA, 88.24% and 40.20% in SpA, 90.89% and 57.81% in other ARDs patients. The causative factors for vitamin D deficiency included SLE per se (OR 12.54, P < 0.001) and high body mass index (BMI) (OR 1.88, P < 0.001). However, the seniors were less likely to have vitamin D deficiency (OR 0.95, P = 0.005). No correlation was disclosed between vitamin D deficiency and gender or disease duration. Hypovitaminosis D is highly prevalent among autoimmune rheumatic diseases population in China. The SLE per se and the obesity are the risk factors for vitamin D deficiency. Clinicians are advised to supplement vitamin D in these patients. PMID:27335701

    2010-01-01

    Background To identify incorrect beliefs and common knowledge about rheumatic diseases in the general population. Methods Participants were selected during the follow-up of a representative cohort of adult population of Porto, Portugal; 1626 participants completed a questionnaire that included general knowledge items about rheumatic diseases. Discrete and continuous latent variable models were used to identify knowledge flaws and the target groups. Odds ratios (OR) estimated by multinomial logistic regression, and 95% confidence intervals (95%CI) were computed to evaluate magnitude of associations. Results A continuous latent variable model identified two dimensions: one related to general beliefs (latent 1) and another concerning characteristics, treatment and impact of rheumatic diseases (latent 2). A 3-class latent variable model refined these results: the first class presented the lowest probabilities of correct answer for items associated with the first latent (mean of 39%), and the second class presented the lowest probabilities of correct answer for items with the second latent (mean of 62%). The third class showed the highest probability of a correct answer for almost all the items (mean of 79%). The age and sex standardized prevalence of the classes was 25.7%, 30.8% and 43.5%. Taking class 2 as reference, class 1 was positively associated with the presence of rheumatic diseases (OR = 2.79; CI95% = (2.10-3.70)), with females (OR = 1.28 CI95% = (0.99-1.67)) and older individuals (OR = 1.04; CI95% = (1.03-1.05)), and was negatively associated with education (OR = 0.84; CI95% = (0.81-0.86)); class 3 was positively associated with education (OR = 1.03; CI95% = (1.00-1.05)) and the presence of rheumatic diseases (OR = 1.29; CI95% = (0.97-1.70)). Conclusions There are several knowledge flaws about rheumatic diseases in the general public. One out of four participants considered false general beliefs as true and approximately 30% did not have detailed knowledge on

    Three priority areas in the prevention, diagnosis and management of acute rheumatic fever (ARF) and rheumatic heart disease (RHD) were identified and discussed in detail: 1. Echocardiography and screening/diagnosis of RHD – Given the existing uncertainty it remains premature to advocate for or to incorporate echocardiographic screening for RHD into Australian clinical practice. Further research is currently being undertaken to evaluate the potential for echocardiography screening. 2. Secondary prophylaxis – Secondary prophylaxis (long acting benzathine penicillin injections) must be seen as a priority. Systems-based approaches are necessary with a focus on the development and evaluation of primary health care-based or led strategies incorporating effective health information management systems. Better/novel systems of delivery of prophylactic medications should be investigated. 3. Management of advanced RHD – National centres of excellence for the diagnosis, assessment and surgical management of RHD are required. Early referral for surgical input is necessary with multidisciplinary care and team-based decision making that includes patient, family, and local health providers. There is a need for a national RHD surgical register and research strategy for the assessment, intervention and long-term outcome of surgery and other interventions for RHD. PMID:22726405

    Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) are autoimmune conditions resulting from infection with group A streptococcus. Current management of these conditions includes secondary antibiotic prevention. This comprises regular 3 to 4 weekly long-acting intramuscular benzathine penicillin injections. Secondary antibiotic prevention aims to protect individuals against reinfection with group A streptococcus, thereby preventing recurrent ARF and the risk of further damage to the heart valves. However, utilization of benzathine penicillin can be poor leaving patients at risk of avoidable and progressive heart damage. This review utilizes the Chronic Care Model as a framework to discuss initiatives to enhance the delivery of secondary antibiotic prophylaxis for ARF and RHD. Results from the search strategy utilized revealed that there is limited pertinent published evidence. The evidence that is available suggests that register/recall systems, dedicated health teams for delivery of secondary antibiotic prophylaxis, education about ARF and RHD, linkages with the community (particularly between health services and schools), and strong staff-patient relationships may be important. However, it is difficult to generalize findings from individual studies to other settings and high quality studies are lacking. Although secondary antibiotic prophylaxis is an effective treatment for those with ARF or RHD, the difficulties in implementing effective programs that reduce the burden of ARF and RHD demonstrates the importance of ongoing work in developing and evaluating research translation initiatives.

    The aim of the study The aim of the study was to evaluate the current state of nutrition of patients with rheumatic diseases in the Polish population. Material and methods An anonymous questionnaire study was carried out among the patients of the Institute of Rheumatology in Warsaw in the fourth quarter of 2012. Five hundred questionnaires were distributed, and 397 questionnaires were collected and accepted for further analysis (response rate = 79%). Results Overweight or obesity was present in more than half (53%) of the patients (overweight in 30.5% of respondents, obesity in 22.6%). Among obese subjects, 43% of men and 37% of women in the study think that their diet is correct. Sixty-eight percent of respondents declared that they do not follow any special diet and only 18% declared that they follow a diet with a reduced quantity of monosaccharides (no sweets). A milk-free diet was followed by 7% of respondents, a meat-free diet by 6%, and a fruit-and-vegetable diet by 5%. Dietary supplements were regularly used by 26.7% of respondents, whereas 33.8% did not use them at all. The average assessment of physical aptitude (Health Assessment Questionnaire – HAQ) in the group of respondents was 0.71. No statistically significant differences were found between higher level of disability (e.g. HAQ ≥ 1) and the type of diet followed (p = 0.678) or body mass index (BMI) value (p = 0.864) in relation to persons with the value of HAQ < 1. Conclusions More than half of patients suffering from rheumatic diseases are overweight or obese, which corresponds to the body weight profile of the population of Poland. Most patients diagnosed with rheumatic diseases do not follow any special diet. In spite of the frequent use of dietary supplements, the patients do not consult a doctor or a dietician about it. The type of diet and BMI value do not differ according to the level of disability.

    Objective To determine the frequency of lost to follow-up (LTFU) in the setting of usual care for outpatients with rheumatic diseases including RA, SLE, AS, and Ps/PsA, to explore the associated demographic factors, and to investigate the reasons for being LTFU from the original medical care. Methods Patients registered between May 2011 and January 2014 at the rheumatology outpatient department of a medical center were included. Those who did not attend their scheduled appointment were defined as LTFU. Univariate and multivariate logistic regression were used to analyze the factors for being LTFU. Results A total of 781 patients were enrolled, including 406 patients with RA, 174 with SLE, 136 with AS, and 65 with Ps/PsA. The frequency of LTFU was 23.9%, 25.9%, 35.3%, and 35.4%, respectively. The frequency of LTFU was significantly different between the four rheumatic diseases (p = 0.028). In multivariate logistic regression analysis, an older age increased being LTFU in the patients with RA (OR 1.02; 95% CI 1.00–1.04; p = 0.033), but reduced being LTFU in those with Ps/PsA (OR 0.96; 95% CI 0.92–0.99; p = 0.021). Female patients with SLE and Ps/PsA were more likely to be LTFU, although this did not reach statistical significance (p = 0.056 and 0.071, respectively). The most common reason for being LTFU was moving to other district hospitals from the original medical center due to convenience for the patients with RA and SLE, and stopping medication due to minimal symptoms for the patients with AS and Ps/PsA. Conclusions The frequency of LTFU in patients with rheumatic diseases is high. Associated demographic factors included older age in RA, female gender in SLE and Ps/PsA, and younger age in Ps/PsA, with various reasons for being LTFU. Recognizing these associated factors and reasons for being LTFU may help to improve the attendance of patients and the quality of medical care. PMID:26950470

    Enteric microflora profiles vary considerably between active inflammatory bowel diseases (IBD) and healthy conditions. Intestinal microflora may partake in the pathogenesis of IBD by one or some ways: specific pathogenic infection induces abnormal intestinal mucosal inflammation; aberrant microflora components trigger the onset of IBD; abnormal host immune response loses normal immune tolerance to luminal components; luminal antigens permeate through the defective mucosal barrier into mucosal lamina propria and induce abnormal inflammatory response. Preliminary studies suggest that administration of probiotics may be benefit for experimental colitis and clinical trials for IBD. Researches have been studying the function of probiotics. Introduction of probiotics can balance the aberrant enteric microflora in IBD patients, and reinforce the various lines of intestinal defence by inhibiting microbial pathogens growth, increasing intestinal epithelial tight junction and permeability, modulating immune response of intestinal epithelia and mucosal immune cells, secreting antimicrobial products, decomposing luminal pathogenic antigens.

    Objective: There are limited studies in Latin America regarding the chronic consequences of the Chikungunya virus (CHIK), such as post-CHIK chronic inflammatory rheumatism (pCHIK-CIR). We assessed the largest cohort so far of pCHIK-CIR in Latin America, at the municipality of La Virginia, Risaralda, a new endemic area of CHIK in Colombia. Methods: We conducted a cohort retrospective study in Colombia of 283 patients diagnosed with CHIK that persisted with pCHIK-CIR after a minimum of 6 weeks and up to a maximum of 26.1 weeks. pCHIK cases were identified according to validated criteria via telephone. Results: Of the total CHIK-infected subjects, 152 (53.7%) reported persistent rheumatological symptoms (pCHIK-CIR). All of these patients reported joint pains (chronic polyarthralgia, pCHIK-CPA), 49.5% morning stiffness, 40.6% joint edema, and 16.6% joint redness. Of all patients, 19.4% required and attended for care prior to the current study assessment (1.4% consulting rheumatologists). Significant differences in the frequency were observed according to age groups and gender. Patients aged >40 years old required more medical attention (39.5%) than those ≤40 years-old (12.1%) (RR=4.748, 95%CI 2.550-8.840). Conclusions: According to our results, at least half of the patients with CHIK developed chronic rheumatologic sequelae, and from those with pCHIK-CPA, nearly half presented clinical symptoms consistent with inflammatory forms of the disease. These results support previous estimates obtained from pooled data of studies in La Reunion (France) and India and are consistent with the results published previously from other Colombian cohorts in Venadillo (Tolima) and Since (Sucre).

    The aim of this study was to determine the prevalence of musculoskeletal pain and rheumatic diseases in subjects over 18 years of age from the canton of Cuenca, Ecuador. Cross-sectional analytical community-based study was conducted in subjects over 18 years of age using the validated Community-Oriented Program for the Control of Rheumatic Diseases (COPCORD) questionnaire. Random sampling was used. The questionnaire was administered by standardized health workers. Subjects were visited house by house. Subjects positive for musculoskeletal (MSK) pain in the last 7 days and at some point in life were assessed by rheumatologists to confirm the diagnosis. A total of 4877 subjects participated, with an average age of 42.8 (SD 18.8) years of age; 59.7 % were women; 69.7 % lived in urban areas. 32.5 % reported MSK pain in the last 7 days and 45.7 % at some point in life. The prevalence of knee osteoarthritis was 7.4 %, hand osteoarthritis 5.3 %, low back pain 9.3 %, rheumatoid arthritis 0.8 %, fibromyalgia 2 %, gout 0.4 %, and lupus 0.06 %. Subjects from rural areas reported experiencing more MSK pain in the last 7 days and at some point in life, lower income, poorer health-care coverage, and increased physical activity involving repetitive tasks such as lifting weights or cooking with firewood. MSK pain prevalence was high. Osteoarthritis and low back pain were the most common diseases. Age, sex, physical activity, repetitive tasks, living in a rural area, and lack of health-care coverage were found to be associated with MSK pain. PMID:27023004

    Introduction Rheumatic heart disease (RHD) is a chronic disease affecting the heart valves, secondary to group A streptococcal infection (GAS) and subsequent acute rheumatic fever (ARF). However, RHD cure and preventative measures are inextricably linked with socioeconomic development, as the disease mainly affects children and young adults living in poverty. In order to address RHD, public health officials and health policymakers require up-to-date knowledge on the epidemiology of GAS, ARF and RHD, as well as the existing enablers and gaps in delivery of evidence-based care for these conditions. We propose to conduct a systematic review to assess the literature comprehensively, synthesising all existing quantitative and qualitative data relating to RHD in Africa. Methods and analysis We plan to conduct a comprehensive literature search using a number of databases and reference lists of relevant articles published from January 1995 to December 2015. Two evaluators will independently review and extract data from each article. Additionally, we will assess overall study quality and risk of bias, using the Newcastle-Ottawa Scale and the Critical Appraisal Skills Programme criteria for quantitative and qualitative studies, respectively. We will meta-analyse estimates of prevalence, incidence, case fatality and mortality for each of the conditions separately for each country. Qualitative meta-analysis will be conducted for facilitators and barriers in RHD health access. Lastly, we will create a list of key stakeholders. This protocol is registered in the PROSPERO International Prospective Register of systematic reviews, registration number CRD42016032852. Ethics and dissemination The information provided by this review will inform and assist relevant stakeholders in identifying key areas of intervention, and designing and implementing evidence-based programmes and policies at the local and regional level.

    Systemic inflammatory diseases are inflammatory syndromes that are associated with increased cardiovascular morbidity and mortality. The link between inflammatory and cardiovascular diseases can be attributed to coexistence of classical risk factors and of inflammatory mechanisms activated in systemic inflammatory diseases and involving the immune system. Yet, clinical implications of these findings are not entirely clear and deeper knowledge and awareness of cardiac involvement in inflammatory diseases are necessary. The aims of this review are to summarize cardiac involvement in systemic inflammatory diseases and to identify areas where evidence is currently lacking that deserve further investigation in the future.

    Established and emerging data demonstrate that a ‘preclinical’ period of disease precedes the onset of clinical rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), as well as other autoimmune rheumatic diseases (ARDs).This preclinical stage of development of disease is characterized by abnormalities in disease-related biomarkers before the onset of the clinically apparent signs and symptoms. Numerous genetic and environmental risk factors for ARDs have also been identified, and many of these factors are likely to act before the clinical appearance of tissue injury to initiate and/or propagate autoimmunity and autoimmune disease. Thus, biomarkers representative of these autoimmune processes could potentially be used in conjunction with other clinical parameters during the preclinical period of ARDs to predict the future development of clinically apparent disease. This Review focuses on the preclinical stages of RA and SLE, as our current understanding of these diseases can be used to present an overall model of the development of ARDs that might ultimately be used to develop screening programmes and preventive strategies. Important considerations for the future development of such approaches, in particular, the issues that require additional research and how they might be addressed, are also discussed. PMID:24514912

    Rheumatic diseases (RD) self-management interventions are designed to improve health-related quality of life, health care utilization, and perceived self-efficacy. Despite these demonstrated good results, there are several issues that hinder or render less appealing these interventions. One economically and socially viable solution is exploiting the potential of Smartphone technology. This potential comes from Smartphones pervasive presence in actual society, combined with the advantages of being personal, intuitive, and computationally powerful, with capability to support applications and assist its user throughout different activities of daily living and environments persistently. With their global acceptance increasing quickly, there is a great opportunity for mobile health in using Smartphone applications for RD self-management. Besides the potential of such applications, research on the development and evaluation of such applications is in the early stages. Therefore, it is important to foresee its future applicability in order to meet the needs of the twenty-first century. PMID:25168866

    The role of alcohol in causing or aggravating the pathogenesis of inflammatory bowel disease is unclear. For finding a conclusive answer for this valuable question we conducted this review. Only two studies were identified that successfully fulfilled our inclusive criteria. Usual consumption of alcohol reduced the risk compared with less frequent use (odds ratio = 0.57, 95%CI: 0.37-0.86). Light alcoholic drinking has protective effects against development of ulcerative colitis. But this inverse association disappeared when smoking was included. PMID:23539486

    A 28-year-old man with a history of inflammatory bowel disease (IBD) developed sudden-onset chest pain and dyspnea 9 days after esophagogastroduodenoscopy and colonoscopy. A chest radiograph demonstrated pneumomediastinum tracking along the left heart border. The spontaneous pneumomediastinum was presumed to be a complication of his severe colitis. The severity of our patient's symptoms ultimately necessitated a subtotal colectomy, a decision unrelated to the pneumomediastinum. IBD-associated pneumomediastinum can be attributed to retroperitoneal air leakage from severe colitis and usually resolves with conservative management. PMID:26130885

    Inflammatory bowel disease (IBD) in pregnant women in their characteristics do not differ from general population, unless they had operations on the pelvic organs. Women with a first pregnancy, regardless of the activity of IBD have an increased risk of adverse pregnancy and high risk births. Most treatment methods are compatible with pregnancy and breastfeeding. Women affected by IBD should discuss their plans for pregnancy with the doctor first in order to know the possible dangers. Every patient in the IBD during pregnancy must be observed by a gastroenterologist, accoucheur and pediatrician to ensure peace of mother and child. PMID:22830229

    Autonomic neuropathy (AN) is a risk predictor for sudden cardiac death in rheumatoid arthritis (RA) and ankylosing spondylitis (AS). However, the impact of most commonly employed disease-modifying anti-rheumatic drug (DMARD) therapy on autonomic neuropathy in rheumatic diseases is not known. Hence, we investigated the efficacy of DMARDs on autonomic neuropathy in RA and AS. We performed autonomic function assessment in 60 patients in this open-label, 12-week pilot study including 42 patients with RA, 18 with AS, and 30 aged-matched healthy subjects. The methodology included assessment of cardiovascular autonomic reflex tests according to Ewing. Parasympathetic dysfunction was established by performing three tests: heart rate response to deep breathing, standing, and Valsalva tests. Sympathetic dysfunction was examined by applying two tests: blood pressure response to standing and handgrip tests. Sudomotor function was assessed by Sudoscan. Cardiovascular reflex tests were impaired significantly among the patients as compared to healthy subjects (p < 0.05). Autonomic neuropathy was more pronounced in biologic-naive RA and AS patients. After treatment with combination synthetic DMARDs, parasympathetic, and sudomotor dysfunction significantly (p < 0.05) improved in RA and AS. Biologic DMARDs significantly improved parasympathetic, sympathetic and peripheral sympathetic autonomic neuropathy (p < 0.05) in biologic-naive RA and AS patients. In conclusion, synthetic DMARDs improved parasympathetic and sudomotor dysfunction in both DMARD-naive RA and AS patients. However, biologic DMARDs improved parasympathetic, sympathetic and sudomotor dysfunction to a greater extent than synthetic DMARDs in both RA and AS patients. PMID:24928343

    Interleukin-2 (IL-2) and T cell subpopulations were evaluated in children with rheumatic heart disease (RHD). Three groups were included: 13 patients with active RHD, 12 with non-active RHD, and 14 control children. Serum IL-2 and T cell subpopulations were measured by radioimmunoassay and monoclonal antibodies respectively. Patients with active RHD showed a significant increase in IL-2 concentrations and helper:suppressor (H:S) ratio compared with controls with a mean (SEM) IL-2 of 3.48 (0.62) v 1.26 (0.16) U/ml and H:S ratio 2.31 (0.14) v 1.66 (0.04). There was a significant decrease in T suppressor (CD8+) and pan T (CD3+) cells compared with controls with a mean (SEM) for CD8+ of 23.75 (1.19) v 32.23 (0.56)% and CD3+ of 79.55 (0.94) v 85.00 (0.11)%. Patients with non-active RHD showed a significant decrease only in the CD3+ cells (78.20 (0.20)%) when compared with controls. A deficiency of CD3+ cells is a constant finding in patients with RHD, whether the disease is active or not. There was a significant increase in IL-2 concentration with a significant decrease in CD8+ cells in patients with active RHD in comparison with the non-active group (mean (SEM) IL-2 of 3.48 (0.62) v 1.85 (0.24) U/ml and CD8+ of 23.75 (1.19) v 28.83 (1.91)%). Thus an increase in IL-2 and a decrease in CD8+ cells may be related to rheumatic activity. T helper (CD4+) cells did not differ significantly between groups. PMID:1471890

    Rheumatologists are still relatively unaware of the causes, presentation, diagnosis and management of radicular pain. This is against a background of increasing evidence of the presence and importance of radicular problems in patients with rheumatological disorders. When they coexist in patients, differentiating between nociceptive and neuropathic pain is clinically important because these components require different pain management strategies. Consequently, it is essential that rheumatologists become skilled in identifying as well as managing both forms of pain. This review will serve to further increase awareness among rheumatologists of this important issue as well as discuss the practical aspects of managing these conditions. The evaluation of patients requires very careful history taking and full thorough neurological examination. Diagnostic testing is suggested mainly to confirm the diagnosis and aetiology in patients with persistent symptoms despite conservative treatment. Neuroimaging is recommended for patients with acute radicular pain with progressive neurological deficits or those with high suspicion of neoplasm or epidural abscess. If neuroimaging does not confirm diagnosis, electrophysiology studies may be helpful. The management of this condition is multifaceted and involves physicians and allied healthcare professionals as well as the patients who should be encouraged to participate in self-management programmes. Nociceptive and neuropathic pain often coexists in patients with rheumatic disease. There are challenges to making the diagnosis of radicular pain in these patients. The diagnosis is primarily clinical but pathophysiological issues, diversity in symptoms, the multiple mechanisms of action and difficulties in communication between patients and their doctors as well as variable response to therapy pose challenges to the effective management of these patients. Despite these difficulties and challenges, it is essential that rheumatologists

    Dietary intake of the micronutrient selenium is essential for normal immune functions. Selenium is cotranslationally incorporated as the 21st amino acid, selenocysteine, into selenoproteins that function to modulate pathways involved in inflammation. Epidemiological studies have suggested an inverse association between selenium levels and inflammatory bowel disease (IBD), which includes Crohn's disease and ulcerative colitis that can potentially progress to colon cancer. However, the underlying mechanisms are not well understood. Here we summarize the current literature on the pathophysiology of IBD, which is multifactorial in origin with unknown etiology. We have focused on a few selenoproteins that mediate gastrointestinal inflammation and activate the host immune response, wherein macrophages play a pivotal role. Changes in cellular oxidative state coupled with altered expression of selenoproteins in macrophages drive the switch from a proinflammatory phenotype to an anti-inflammatory phenotype to efficiently resolve inflammation in the gut and restore epithelial barrier integrity. Such a phenotypic plasticity is accompanied by changes in cytokines, chemokines, and bioactive metabolites, including eicosanoids that not only mitigate inflammation but also partake in restoring gut homeostasis through diverse pathways involving differential regulation of transcription factors such as nuclear factor-κB and peroxisome proliferator-activated receptor-γ. The role of the intestinal microbiome in modulating inflammation and aiding in selenium-dependent resolution of gut injury is highlighted to provide novel insights into the beneficial effects of selenium in IBD.

    Background Rheumatic heart disease (RHD) prevalence and mortality rates remain especially high in many parts of Africa. While effective prevention and treatment exist, coverage rates of the various interventions are low. Little is known about the comparative cost-effectiveness of different RHD interventions in limited resource settings. We developed an economic evaluation tool to assist ministries of health in allocating resources and planning RHD control programs. Methodology/Principal Findings We constructed a Markov model of the natural history of acute rheumatic fever (ARF) and RHD, taking transition probabilities and intervention effectiveness data from previously published studies and expert opinion. Our model estimates the incremental cost-effectiveness of scaling up coverage of primary prevention (PP), secondary prevention (SP) and heart valve surgery (VS) interventions for RHD. We take a healthcare system perspective on costs and measure outcomes as disability-adjusted life-years (DALYs), discounting both at 3%. Univariate and probabilistic sensitivity analyses are also built into the modeling tool. We illustrate the use of this model in a hypothetical low-income African country, drawing on available disease burden and cost data. We found that, in our hypothetical country, PP would be cost saving and SP would be very cost-effective. International referral for VS (e.g., to a country like India that has existing surgical capacity) would be cost-effective, but building in-country VS services would not be cost-effective at typical low-income country thresholds. Conclusions/Significance Our cost-effectiveness analysis tool is designed to inform priorities for ARF/RHD control programs in Africa at the national or subnational level. In contrast to previous literature, our preliminary findings suggest PP could be the most efficient and cheapest approach in poor countries. We provide our model for public use in the form of a Supplementary File. Our research has

    Not all cases of rheumatic fever (RF) end up as rheumatic heart disease (RHD). The fact raises the possibility of existence of a subgroup with characteristics that prevent RF patients from developing the RHD. The present study aimed at exploring the risk factors among patients with RHD. The study assessed the risk of RHD among people both with and without RF. In total, 103 consecutive RHD patients were recruited as cases who reported to the National Centre for Control of Rheumatic Fever and Heart Disease, Dhaka, Bangladesh. Of 309 controls, 103 were RF patients selected from the same centre, and the remaining 206 controls were selected from Shaheed Suhrawardy Medical College Hospital, who got admitted for other non-cardiac ailments. RHD was confirmed by auscultation and colour Doppler echocardiography. RF was diagnosed based on the modified Jones criteria. An unadjusted odds ratio was generated for each variable, with 95% confidence interval (CI), and only significant factors were considered candidate for multivariate analysis. Three separate binary logistic regression models were generated to assess the risk factors of RF, risk factors of RHD compared to non-rheumatic control patients, and risk factors of RHD compared to control with RF. RF and RHD shared almost a similar set of risk factors in the population. In general, age over 19 years was found to be protective of RF; however, age of the majority (62.1%) of the RHD cases was over 19 years. Women [odds ratio (OR) = 2.2, 95% CI 1.1-4.3], urban resident (OR = 3.1, 95% CI 1.2-8.4), dwellers in brick-built house (OR = 3.6, 95% CI 1.6-8.1), having > 2 siblings (OR = 3.1, 95% CI 1.5- 6.3), offspring of working mothers (OR = 7.6, 95% CI 2.0-24.2), illiterate mother (OR = 2.6, 95% CI 1.2-5.8), and those who did not brush after taking meals (OR = 2.5, 95% CI 1.0-6.3) were more likely to develop RF. However, more than 5 members in a family showed a reduced risk of RF. RHD shared almost a similar set of factors in

    Objectives To project the cost-effectiveness of population-based echo screening to prevent rheumatic heart disease (RHD) consequences. Background RHD is a leading cause of cardiovascular mortality and morbidity during adolescence and young adulthood in low- and middle-per capita income settings. Echocardiography-based screening approaches can dramatically expand the number of children identified at risk of progressive RHD. Cost-effectiveness analysis can inform public health agencies and payers about the net economic benefit of such large-scale population-based screening. Methods A Markov model was constructed comparing a no-screen to echo screen approach. The echo screen program was modeled as a 2-staged screen of a cohort of 11-year-old children with initial short screening performed by dedicated technicians and follow-up complete echo by cardiologists. Penicillin RHD prophylaxis was modeled to only reduce rheumatic fever recurrence-related exacerbation. Quality-adjusted life years (QALYs) and societal costs (in 2010 Australian dollars) associated with each approach were estimated. One-way, two-way and probabilistic sensitivity analyses were performed on RHD prevalence and transition probabilities; echocardiography test characteristics; and societal level costs including supplies, transportation, and labor. Results The incremental costs and QALYs of the screen compared to no screen strategy were −$432 (95% CI = −$1357 to $575) and 0.007 (95% CI = −0.0101 to 0.0237), respectively. The joint probability that the screen was both less costly and more effective exceeded 80%. Sensitivity analyses suggested screen strategy dominance depends mostly on the probability of transitioning out of sub-clinical RHD. Conclusion Two-stage echo RHD screening and secondary prophylaxis may achieve modestly improved outcomes at lower cost compared to clinical detection and deserves closer attention from health policy stakeholders.

    The marijuana plant Cannabis sativa has been used for centuries as a treatment for a variety of ailments. It contains over 60 different cannabinoid compounds. Studies have revealed that the endocannabinoid system is involved in almost all major immune events. Cannabinoids may, therefore, be beneficial in inflammatory disorders. In murine colitis, cannabinoids decrease histologic and microscopic inflammation. In humans, cannabis has been used to treat a plethora of gastrointestinal problems, including anorexia, emesis, abdominal pain, diarrhea, and diabetic gastroparesis. Despite anecdotal reports on medical cannabis in inflammatory bowel disease (IBD), there are few controlled studies. In an observational study in 30 patients with Crohn's disease (CD), we found that medical cannabis was associated with improvement in disease activity and reduction in the use of other medications. In a more recent placebo-controlled study in 21 chronic CD patients, we showed a decrease in the CD activity index >100 in 10 of 11 subjects on cannabis compared to 4 of 10 on placebo. Complete remission was achieved in 5 of 11 subjects in the cannabis group and 1 of 10 in the placebo group. Yet, in an additional study, low-dose cannabidiol did not have an effect on CD activity. In summary, evidence is gathering that manipulating the endocannabinoid system can have beneficial effects in IBD, but further research is required to declare cannabinoids a medicine. We need to establish the specific cannabinoids, as well as appropriate medical conditions, optimal dose, and mode of administration, to maximize the beneficial effects while avoiding any potential harmful effects of cannabinoid use.

  12. Pain and Inflammatory Bowel Disease

    Bielefeldt, Klaus; Davis, Brian; Binion, David G.

    2010-01-01

    Abdominal pain is a common symptom of inflammatory bowel disease (IBD: Crohn’s disease, ulcerative colitis). Pain may arise from different mechanisms, which can include partial blockage and gut distention as well as severe intestinal inflammation. A majority of patients suffering from acute flares of IBD will experience pain, which will typically improve as disease activity decreases. However, a significant percentage of IBD patients continue experiencing symptoms of pain despite resolving inflammation and achieving what appears to be clinical remission. Current evidence suggests that sensory pathways sensitize during inflammation, leading to persistent changes in afferent neurons and central nervous system pain processing. Such persistent pain is not only a simple result of sensory input. Pain processing and even the activation of sensory pathways is modulated by arousal, emotion, and cognitive factors. Considering the high prevalence of iatrogenic as well as essential neuropsychiatric comorbidities including anxiety and depression in IBD patients, these central modulating factors may significantly contribute to the clinical manifestation of chronic pain. The improved understanding of peripheral and central pain mechanisms is leading to new treatment strategies that view pain as a biopsychosocial problem. Thus, improving the underlying inflammation, decreasing the excitability of sensitized afferent pathways, and altering emotional and/or cognitive functions may be required to more effectively address the difficult and disabling disease manifestations.

    2015-01-01

    The danger model was proposed by Polly Matzinger as complement to the traditional self-non-self- (SNS-) model to explain the immunoreactivity. The danger model proposes a central role of the tissular cells' discomfort as an element to prime the immune response processes in opposition to the traditional SNS-model where foreignness is a prerequisite. However recent insights in the proteomics of diverse tissular cells have revealed that under stressful conditions they have a significant potential to initiate, coordinate, and perpetuate autoimmune processes, in many cases, ruling over the adaptive immune response cells; this ruling potential can also be confirmed by observations in several genetically manipulated animal models. Here, we review the pathogenesis of rheumatic diseases such as systemic lupus erythematous, rheumatoid arthritis, spondyloarthritis including ankylosing spondylitis, psoriasis, and Crohn's disease and provide realistic approaches based on the logic of the danger model. We assume that tissular dysfunction is a prerequisite for chronic autoimmunity and propose two genetically conferred hypothetical roles for the tissular cells causing the disease: (A) the Impaired cell and (B) the paranoid cell. Both roles are not mutually exclusive. Some examples in human disease and in animal models are provided based on current evidence. PMID:25973436

    Gene-expression profiling is a powerful tool for the discovery of molecular fingerprints that underlie human disease. Microarray technologies allow the analysis of messenger RNA transcript levels for every gene in the genome. However, gene-expression profiling is best viewed as part of a pipeline that extends from sample collection through clinical application. Key genes and pathways identified by microarray profiling should be validated in independent sample sets and with alternative technologies. Analysis of relevant signaling pathways at the protein level is an important step towards understanding the functional consequences of aberrant gene expression. Peripheral blood is a convenient and rich source of potential biomarkers, but surveying purified cell populations and target tissues can also enhance our understanding of disease states. In rheumatic disease, probing the transcriptome of circulating immune cells has shed light on mechanisms underlying the pathogenesis of complex diseases, such as systemic lupus erythematosus. As these discoveries advance through the pipeline, a variety of clinical applications are on the horizon, including the use of molecular fingerprints to aid in diagnosis and prognosis, improved use of existing therapies, and the development of drugs that target relevant genes and pathways.

    Rheumatic heart disease (RHD) is the most important cardiovascular disease in hospital practice in Ethiopia. However, the prevalence rate of RHD at the community level remains unknown. The current survey was undertaken to estimate its prevalence among schoolchildren of a central Ethiopian rural town (Butajira). Accordingly, 92.8% of the entire schoolchildren (n = 3.235) in the town were screened. Their mean age was 13.4 +/- 3.5 years. Fifteen children, accounting for a rate of 4.6/1,000, were noted to have findings consistent with RHD. Females and older children were more frequently affected. Only 2 of the 15 students were aware of their disease, and neither of them were on regular secondary prophylaxis. Our finding is consistent with the hospital-based reports that showed RHD to be a common disorder in clinical practice. At the same time, the lack of awareness about their disease noted among the cases is worrisome and deserves serious attention. PMID:1611634

    Understanding rheumatic diseases from the perspective of chemokine biology has shaped and will continue to shape our approach for targeted drug design. Among different kinds of chemokines, fractalkine/CX3CL1 has been found to play an important role in inflammation, portraying unique functional, and structural characteristics. This review summarizes the emerging role of fractalkine/CX3CL1 from a functional and clinical perspective and provides evidence to validate it as a potential therapeutic target in rheumatic diseases such as rheumatoid arthritis, Sjögren’s syndrome, systemic lupus erythematosus, scleroderma, as well as diseases related to vascular inflammation. From this, recent studies investigating potential therapeutic agents against fractalkine/CX3CL1’s role in pathology have shown promise. PMID:22566871

    Angiogenesis is an important component of pathogenesis of inflammatory bowel disease (IBD). Chronic inflammation and angiogenesis are two closely related processes. Chronic intestinal inflammation is dependent on angiogenesis and this angiogenesis is modulated by immune system in IBD. Angiogenesis is a very complex process which includes multiple cell types, growth factors, cytokines, adhesion molecules, and signal transduction. Lymphangiogenesis is a new research area in the pathogenesis of IBD. While angiogenesis supports inflammation via leukocyte migration, carrying oxygen and nutrients, on the other hand, it has a major role in wound healing. Angiogenic molecules look like perfect targets for the treatment of IBD, but they have risk for serious side effects because of their nature. PMID:26839731

    Background Chronic rheumatic diseases are painful conditions which are not entirely controllable and can place high emotional demands on individuals. Increasing evidence has shown that emotion regulation in terms of actively processing and expressing disease-related emotions are likely to promote positive adjustment in patients with chronic diseases. The Emotional Approach Coping Scale (EAC) measures active attempts to acknowledge, understand, and express emotions. Although tested in other clinical samples, the EAC has not been validated for patients with rheumatic diseases. This study evaluated the data quality, internal consistency reliability, validity and responsiveness of the Norwegian version of the EAC for this group of patients. Methods 220 patients with different rheumatic diseases were included in a cross-sectional study in which data quality and internal consistency were assessed. Construct validity was assessed through comparisons with the Brief Approach/Avoidance Coping Questionnaire (BACQ) and the General Health Questionnaire (GHQ-20). Responsiveness was tested in a longitudinal pretest-posttest study of two different coping interventions, the Vitality Training Program (VTP) and a Self-Management Program (SMP). Results The EAC had low levels of missing data. Results from principal component analysis supported two subscales, Emotional Expression and Emotional Processing, which had high Cronbach's alphas of 0.90 and 0.92, respectively. The EAC had correlations with approach-oriented items in the BACQ in the range 0.17-0.50. The EAC Expression scale had a significant negative correlation with the GHQ-20 of -0.13. As hypothesized, participation in the VTP significantly improved EAC scores, indicating responsiveness to change. Conclusion The EAC is an acceptable and valid instrument for measuring emotional processing and expression in patients with rheumatic diseases. The EAC scales were responsive to change in an intervention designed to promote emotion

    Chikungunya virus (CHIKV) infection is a common cause of febrile arthritis. The most common manifestations of acute infection are fever, symmetrical polyarthralgias or polyarthritis, myalgias, and maculopapular rash. Up to 80% of patients may develop musculoskeletal manifestations that persist longer than 3 months, causing impairment in their quality of life. The most common chronic manifestations are persistent or relapsing-remitting polyarthralgias, polyarthritis, and myalgias. Fingers, wrists, knees, ankles, and toes are the most frequently involved, but proximal joints and axial involvement can occur in the chronic stage. Chronic manifestations of CHIKV infection may resemble those of some autoimmune connective tissue diseases. Furthermore, CHIKV infection can cause cryoglobulinemia and may induce rheumatoid arthritis and seronegative spondyloarthropathies in genetically susceptible individuals. The Centers for Disease Control and Prevention recommend acetaminophen and non steroidal anti-inflammatory drugs for the acute rheumatic manifestations of CHIKV infection. However, some studies suggest that low-dose corticosteroids for about 1-2 months (depending on clinical course) are beneficial in relieving acute rheumatic symptoms. Conversely, hydroxychloroquine in combination with corticosteroids or other disease modifying anti-rheumatic drugs (DMARDs) has been successful in treating chronic rheumatic manifestations. Methotrexate and sulfasalazine (alone or in combination) have also been effective for chronic CHIKV arthritis. Patients with CHIKV infection should be closely monitored to identify those with chronic arthritis who would benefit from a rheumatologic evaluation and early treatment with DMARDs. PMID:26061056

    The optimal method for monitoring quiescent disease in patients with Crohn’s disease (CD) and ulcerative colitis is yet to be determined. Endoscopic evaluation with ileocolonoscopy is the gold standard but is invasive, costly, and time-consuming. There are many commercially available biomarkers that may be used in clinical practice to evaluate disease status in patients with inflammatory bowel disease (IBD), but the most widely adopted biomarkers are C-reactive protein (CRP) and fecal calprotectin (FC). This review summarizes the evidence for utilizing CRP and FC for monitoring IBD during clinical remission and after surgical resection. Endoscopic correlation with CRP and FC is evaluated in each disease state. Advantages and drawbacks of each biomarker are discussed with special consideration of isolated ileal CD. Fecal immunochemical testing, traditionally used for colorectal cancer screening, is mentioned as a potential new alternative assay in the evaluation of IBD. Based on a mixture of information gleaned from biomarkers, clinical status, and endoscopic evaluation, the best treatment decisions can be made for the patient with IBD. PMID:26523100

Vedolizumab has been approved by the FDA and EMA and has demonstrated utility both in the treatment of ulcerative colitis (UC) and Crohn's disease (CD), even in anti-TNF refractory patients. Other monoclonal antibodies with different targets such as PF-005447659 (antiMAd-CAM1), ustekinumab (anti-IL23/IL12) or MEDI2070 (anti-IL23) have shown promising results in distinct clinical scenarios. Mongersen (antisense oligonucleotide anti-Smad7) and oznimod (an SP-1 modulator) are new alternatives with proven efficacy in clinical trials in CD and UC, respectively. Some data suggest that faecal microbiota transplantation could be efficacious in individual patients, although controlled data do not show clear differences with placebo. Autologous stem-cell transplantation has shown long-term efficacy in "ultra-refractory" CD. The number of possible treatments is constantly increasing, and future research should focus both on the selection of the most appropriate treatment for any given patient and on comparative trials between options.

    Prevention of infective endocardit s (IE) is mportant because it has a high mortalty rate.This study sets out to to gather information from patients who were at risk of developing IE of their knowledge of the need for prophylaxis for the disease. Forty-one black patients suffering from severe rheumatic heart disease (RHD) were interviewed. Only one patient (2.4%) was regularly visiting a dentist to maintain good oral health and only five (12.2%) had received advice about the need for antibiotic cover prior to dental extraction. The vast majority of patients (97.5%) visited a dentist only when driven by dental pain, 36.6 % had to travel for more than an hour to reach their nearest dentist, and 87.8% indicated that they brushed their teeth. It may be concluded that in this group of black patients with severe RHD there was a lack of knowledge of the need for and of measures recommended for prophylaxs against IE. In addition, attempts by the health care team to ensure good oral health and access to dental care for these patients were inadequate, if not non-existent. PMID:23951767

    Chronic inflammatory diseases are associated with accelerated atherosclerosis and increased risk of cardiovascular diseases (CVD). As the pathogenesis of atherosclerosis is increasingly recognized as an inflammatory process, similarities between atherosclerosis and systemic inflammatory diseases such as rheumatoid arthritis, inflammatory bowel diseases, lupus, psoriasis, spondyloarthritis and others have become a topic of interest. Endothelial dysfunction represents a key step in the initiation and maintenance of atherosclerosis and may serve as a marker for future risk of cardiovascular events. Patients with chronic inflammatory diseases manifest endothelial dysfunction, often early in the course of the disease. Therefore, mechanisms linking systemic inflammatory diseases and atherosclerosis may be best understood at the level of the endothelium. Multiple factors, including circulating inflammatory cytokines, TNF-α (tumor necrosis factor-α), reactive oxygen species, oxidized LDL (low density lipoprotein), autoantibodies and traditional risk factors directly and indirectly activate endothelial cells, leading to impaired vascular relaxation, increased leukocyte adhesion, increased endothelial permeability and generation of a pro-thrombotic state. Pharmacologic agents directed against TNF-α-mediated inflammation may decrease the risk of endothelial dysfunction and cardiovascular disease in these patients. Understanding the precise mechanisms driving endothelial dysfunction in patients with systemic inflammatory diseases may help elucidate the pathogenesis of atherosclerosis in the general population.

    Glucocorticoid-induced osteoporosis (GIOP) is a serious problem for patients with rheumatic diseases requiring long-term glucocorticoid treatment. Alendronate, a bisphosphonate, has been recommended in the prevention of GIOP. However, the efficacy and safety of alendronate in preventing GIOP remains controversial. We performed a meta-analysis to investigate the efficacy and safety of alendronate in preventing GIOP in patients with rheumatic diseases.We retrieved randomized controlled trials from PubMed, EMBASE, and the Cochrane Library. Two reviewers extracted the data and evaluated the risk of bias and quality of the evidence. We calculated the risk ratio (RR) with a 95% confidence interval (CI) for dichotomous outcomes, and the mean difference (MD) with a 95% CI for continuous outcomes using Review Manager, version 5.3.A total of 339 studies were found, and 9 studies (1134 patients) were included. Alendronate was not able to reduce the incidence of vertebral fractures (RR = 0.63, 95% CI: 0.10-4.04, P = 0.62) and nonvertebral fractures (RR = 0.40, 95% CI: 0.15-1.12, P = 0.08). Alendronate significantly increased the percent change in bone mineral density (BMD) at the lumbar spine (MD = 3.66, 95% CI: 2.58-4.74, P < 0.05), total hip (MD = 2.08, 95% CI: 0.41-3.74, P < 0.05), and trochanter (MD = 1.68, 95% CI: 0.75-2.61, P < 0.05). Significant differences were not observed in the percent change in BMD at the femoral neck (MD = -0.33, 95% CI: -2.79 to 2.13, P = 0.79) and total body (MD = 0.64, 95% CI: -0.06 to 1.34, P = 0.07). No significant differences in the adverse events were observed in patients treated with alendronate versus the controls (RR = 1.00, 95% CI: 0.94-1.07, P = 0.89). The odds of gastrointestinal adverse events were significantly reduced (RR = 0.77, 95% CI: 0.62-0.97, P < 0.05).Our analysis suggests that alendronate can increase the percent change in BMD at the lumbar spine, total hip, and

    Background Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) persist in many low- and middle-income countries. To date, the cost-effectiveness of population-based, combined primary and secondary prevention strategies has not been assessed. In the Pinar del Rio province of Cuba, a comprehensive ARF/RHD control program was undertaken over 1986 – 1996. The present study analyzes the cost-effectiveness of this Cuban program. Methods and Findings We developed a decision tree model based on the natural history of ARF/RHD, comparing the costs and effectiveness of the 10-year Cuban program to a “do nothing” approach. Our population of interest was the cohort of children aged 5 – 24 years resident in Pinar del Rio in 1986. We assessed costs and health outcomes over a lifetime horizon, and we took the healthcare system perspective on costs but did not apply a discount rate. We used epidemiologic, clinical, and direct medical cost inputs that were previously collected for publications on the Cuban program. We estimated health gains as disability-adjusted life years (DALYs) averted using standard approaches developed for the Global Burden of Disease studies. Cost-effectiveness acceptability thresholds were defined by one and three times per capita gross domestic product per DALY averted. We also conducted an uncertainty analysis using Monte Carlo simulations and several scenario analyses exploring the impact of alternative assumptions about the program’s effects and costs. We found that, compared to doing nothing, the Cuban program averted 5051 DALYs (1844 per 100,000 school-aged children) and saved $7,848,590 (2010 USD) despite a total program cost of $202,890 over 10 years. In the scenario analyses, the program remained cost saving when a lower level of effectiveness and a reduction in averted years of life lost were assumed. In a worst-case scenario including 20-fold higher costs, the program still had a 100% of being cost-effective and an 85% chance

    Quality of life (QoL) is a complex outcome and rheumatologic patients typically exhibit several comorbidities with a negative impact. In this study, we analyzed with respect to QoL for the first time a wide range of physical and psychological factors, including individual, clinical and disease-related parameters, mental health disorders, sexual dysfunction, and cardiovascular comorbidities among consecutive rheumatologic patients. QoL was evaluated using the EuroQol 5D (EQ-5D) utility index. The Health Assessment Questionnaire (HAQ) Disability Index, and the HAQ Pain Visual Analogue Scale were used as measures of physical disability and arthritis-related pain, respectively. The Hamilton Anxiety Scale and Zung Self-Rating Depression Scale, the International Index of Erectile Function and the Female Sexual Functioning Index were completed by all patients. In total, 360 patients were included, 301 females and 59 males. In the univariate analysis, pain, physical disability (p < 0.001 for both), disease duration (p = 0.014), anxiety and depression (p < 0.001 for both), as well as sexual dysfunction (p = 0.001 for females, p = 0.042 for males), correlated with QoL. Female sex (p < 0.001), advanced age (p = 0.029), lower educational level (p = 0.005), and cardiovascular factors (hypertension, dyslipidemia, diabetes, lack of systemic exercise) also appeared to negatively affect QoL. However, in the multiple regression model, only anxiety, pain, physical disability (p < 0.001 for all), and disease duration (p = 0.019) remained significant predictors of QoL. The emotional side and the disease-related physiological mode of rheumatic diseases appear as major independent correlates of QoL among rheumatologic patients, who may thus benefit the most from combined supportive psychological and pain-relieving interventions.

    We conducted a long-term follow-up study in patients with rheumatic diseases who were candidates for biologics treatment to evaluate the effects of biologic agents on the risk of tuberculosis infection and the effect of prophylactic treatment on tuberculosis activation. One hundred one patients with rheumatic diseases who were candidates for biologics treatment were recruited, and 57 healthy subjects were recruited as controls. Tuberculin skin test (TST) and the T-SPOT.TB test were performed for all subjects at baseline. Follow-up testing by the T-SPOT.TB assay was performed every 6 months in patients with rheumatic diseases and at 2 years of recruitment in the healthy controls. In patients with rheumatic diseases and healthy controls, the TST-positive (induration, ≥10 mm) rates were 37.6% (38/101) and 34.0% (18/53), respectively (P > 0.05), while the T-SPOT.TB-positive rates were 46.5% (47/101) and 21.1 (12/57), respectively (P = 0.0019). Fifty-two patients were followed up at month 6 with a T-SPOT.TB-positive rate of 40.4%, and 49 were followed up for ≥12 months with a T-SPOT.TB-positive rate of 36.7%, with no significant difference in the positive rate at different time points including baseline (P > 0.05). Long-term follow-up revealed that conversion to T-SPOT.TB positivity occurred only in the biologics treatment group, with a positive conversion rate of 11.2% (4/38). Most importantly, no latent tuberculosis developed into active tuberculosis during follow-up with T-SPOT.TB screening and preemptive treatment with isoniazid. Biologics treatment appears to increase the risk of tuberculosis infection. However, tuberculosis activation could be prevented by preemptive isoniazid treatment in patients with latent tuberculosis infection while receiving biologics therapy. PMID:23554465

    We designed a pilot study of a training module for nurses to perform rheumatic heart disease echocardiography screening in a resource-poor setting. The aim was to determine whether nurses given brief, focused, basic training in echocardiography could follow an algorithm to potentially identify cases of rheumatic heart disease requiring clinical referral, by undertaking basic two-dimensional and colour Doppler scans. Training consisted of a week-long workshop, followed by 2 weeks of supervised field experience. The nurses' skills were tested on a blinded cohort of 50 children, and the results were compared for sensitivity and specificity against echocardiography undertaken by an expert, using standardised echocardiography definitions for definite and probable rheumatic heart disease. Analysis of the two nurses' results revealed that when a mitral regurgitant jet length of 1.5 cm was used as the trigger for rheumatic heart disease identification, they had a sensitivity of 100% and 83%, respectively, and a specificity of 67.4% and 79%, respectively. This pilot supports the principle that nurses, given brief focused training and supervised field experience, can follow an algorithm to undertake rheumatic heart disease echocardiography in a developing country setting to facilitate clinical referral with reasonable accuracy. These results warrant further research, with a view to developing a module to guide rheumatic heart disease echocardiographic screening by nurses within the existing public health infrastructure in high-prevalence, resource-poor regions.

    The therapeutic efficacy and toxicity of many commonly employed drugs show interindividual variations that relate to several factors, including genetic variability in drug-metabolizing enzymes, transporters or targets. The study of the genetic determinants influencing interindividual variations in drug response is known as pharmacogenetics. The ability to identify, through preliminary genetic screening, the patients most likely to respond positively to a medication should facilitate the best choice of treatment for each patient; drugs likely to exhibit low efficacy or to give negative side-effects can be avoided. Among the medications used for inflammatory bowel disease, the best studied pharmacogenetically is azathioprine. The hematopoietic toxicity of azathioprine is due to single nucleotide polymorphisms in the thiopurine S-methyltransferase enzyme. Additionally, likely gene targets have been investigated to predict the response to glucocorticoids and infliximab, a monoclonal antibody against tumour necrosis factor that induces remission in approximately 30-40% of patients. However, no genetic predictor of response has been identified in either case. PMID:15157830

    Objective Current recommendations advocate treatment with disease-modifying anti-rheumatic drugs (DMARDs) in all patients with active rheumatoid arthritis (RA). We investigated the frequency of and reasons for inconsistent DMARD use among patients in a clinical rheumatology cohort. Methods Patients in the Brigham Rheumatoid Arthritis Sequential Study were studied for DMARD use (any or none) at each semi-annual study time point during the first two study years. Inconsistent use was defined as DMARD use at ≤40 % of study time points. Characteristics were compared between inconsistent and consistent users (>40%), and factors associated with inconsistent DMARD use were determined through multivariate logistic regression. A medical record review was performed to determine the reasons for inconsistent use. Results Of 848 patients with ≥4 out of 5 visits recorded, 55 (6.5%) were inconsistent DMARD users. Higher age, longer disease duration and rheumatoid factor negativity were statistically significant correlates of inconsistent use in the multivariate analyses. The primary reasons for inconsistent use identified through chart review, allowing for up to 2 co-primary reasons, were inactive disease (n=28, 50.9%), intolerance to DMARDs (n=18, 32.7%), patient preference (n=7, 12.7%), comorbidity (n=6, 10.9%), DMARDs not being effective (n=3, 5.5%), and pregnancy (n=3, 5.5%). During subsequent follow-up, 14/45 (31.1%) of inconsistent users with sufficient data became consistent users of DMARDs. Conclusion A small proportion of RA patients in a clinical rheumatology cohort were inconsistent DMARD users during the first two years of follow up. While various patient factors correlate with inconsistent use, many patients re-start DMARDs and become consistent users over time. PMID:25320216

    Chronic inflammation with the presence of excess serum acute-phase proteins, cytokines and cell adhesion molecules is increasingly being implicated in atherosclerosis. The association between inflammatory bowel disease (IBD) and coronary artery disease (CAD) is unstudied. This is a preliminary, thesis-generating cross-sectional study aimed at evaluating the presence of traditional atherosclerotic risk factors in patients with IBD and CAD compared with the control population. The medical records of 42 consecutive IBD patients with CAD from 1999 to 2005 (27 men) were reviewed for the Framingham risk factors. The Framingham risk score (FRS) is calculated based on age, sex, hypertension, diabetes and hyperlipidemia. FRS of patients with IBD and CAD was compared with the FRS of 137 age- and sex-matched (102 men) consecutive patients with CAD (controls). When the Framingham risk score adjusted for group and gender with age as a covariate, the adjusted total FRS score was higher in patients with CAD alone (10.0 [3.75]) as compared to those with; IBD and CAD: (8.1 [3.47]; p = 0.001). FRS is lower in cases (patients with IBD and CAD) when compared with the controls (CAD alone). PMID:19529899

    Background Rheumatic heart disease (RHD) remains a major health concern for Aboriginal Australians. A key component of RHD control is prevention of recurrent acute rheumatic fever (ARF) using long-term secondary prophylaxis with intramuscular benzathine penicillin (BPG). This is the most important and cost-effective step in RHD control. However, there are significant challenges to effective implementation of secondary prophylaxis programs. This project aimed to increase understanding and improve quality of RHD care through development and implementation of a continuous quality improvement (CQI) strategy. Methods We used a CQI strategy to promote implementation of national best-practice ARF/RHD management guidelines at primary health care level in Indigenous communities of the Northern Territory (NT), Australia, 2008–2010. Participatory action research methods were employed to identify system barriers to delivery of high quality care. This entailed facilitated discussion with primary care staff aided by a system assessment tool (SAT). Participants were encouraged to develop and implement strategies to overcome identified barriers, including better record-keeping, triage systems and strategies for patient follow-up. To assess performance, clinical records were audited at baseline, then annually for two years. Key performance indicators included proportion of people receiving adequate secondary prophylaxis (≥80% of scheduled 4-weekly penicillin injections) and quality of documentation. Results Six health centres participated, servicing approximately 154 people with ARF/RHD. Improvements occurred in indicators of service delivery including proportion of people receiving ≥40% of their scheduled BPG (increasing from 81/116 [70%] at baseline to 84/103 [82%] in year three, p = 0.04), proportion of people reviewed by a doctor within the past two years (112/154 [73%] and 134/156 [86%], p = 0.003), and proportion of people who received influenza vaccination (57

    Inflammatory bowel disease can impact individuals at a young age, thus compromising their work productivity. Besides the inability to engage in gainful work, the concept of disability also relates to the patients' diminished ability to undertake household and social activities. A literature search was performed of recent literature, and all articles containing information about the impact of inflammatory bowel disease on disability or any work-related outcomes were included. Recent studies suggest that 9 to 19% of inflammatory bowel disease patients suffer from short-term absences from work and 19 to 22% are on long-term disability. Crohn's disease patients reported being more affected by their disease than ulcerative colitis patients. A comparison of results from different studies is difficult due to the lack of consensus on how to define and measure disability. Additional research is needed to better quantify disability in inflammatory bowel disease patients. PMID:25231757

    Coeliac disease and inflammatory bowel disease are chronic inflammatory conditions of gastrointestinal tract with complex aetiology with genetic, environmental and immunological factors contributing to its pathogenesis. It was noted that immune-mediated disorders often coexist. There is well-known association between coeliac disease and type 1 diabetes and ulcerative colitis and primary sclerosing cholangitis. However, growing body of literature suggests the association between coeliac disease and inflammatory bowel disease, particularly ulcerative colitis. This is an extremely rare problem in paediatric gastroenterology. To date there have been reported several cases of children with coexisting coeliac disease and inflammatory bowel disease.

    In this review, we provide an update on genome-wide association studies (GWAS) in inflammatory bowel disease (IBD). In addition, we summarize progress in defining the functional consequences of associated alleles for coding and noncoding genetic variation. In the small minority of loci where major association signals correspond to nonsynonymous variation, we summarize studies defining their functional effects and implications for therapeutic targeting. Importantly, the large majority of GWAS-associated loci involve noncoding variation, many of which modulate levels of gene expression. Recent expression quantitative trait loci (eQTL) studies have established that the expression of most human genes is regulated by noncoding genetic variations. Significant advances in defining the epigenetic landscape have demonstrated that IBD GWAS signals are highly enriched within cell-specific active enhancer marks. Studies in European ancestry populations have dominated the landscape of IBD genetics studies, but increasingly, studies in Asian and African-American populations are being reported. Common variation accounts for only a modest fraction of the predicted heritability and the role of rare genetic variation of higher effects (ie, odds ratios markedly deviating from 1) is increasingly being identified through sequencing efforts. These sequencing studies have been particularly productive in more severe very early onset cases. A major challenge in IBD genetics will be harnessing the vast array of genetic discovery for clinical utility through emerging precision medical initiatives. In this article, we discuss the rapidly evolving area of direct-to-consumer genetic testing and the current utility of clinical exome sequencing, especially in very early onset, severe IBD cases. We summarize recent progress in the pharmacogenetics of IBD with respect to partitioning patient responses to anti-TNF and thiopurine therapies.

    Objective To estimate the association between fine particulate (PM2.5) and nitrogen dioxide (NO2) pollution and systemic autoimmune rheumatic diseases (SARDs). Methods Associations between ambient air pollution (PM2.5 and NO2) and SARDs were assessed using land-use regression models for Calgary, Alberta and administrative health data (1993-2007). SARD case definitions were based on ≥2 physician claims, or ≥1 rheumatology billing code; or ≥1 hospitalization code (for systemic lupus, Sjogren's Syndrome, scleroderma, polymyositis, dermatomyositis, or undifferentiated connective tissue disease). Bayesian hierarchical latent class regression models estimated the probability that each resident was a SARD case, based on these case definitions. The sum of individual level probabilities provided the estimated number of cases in each area. The latent class model included terms for age, sex, and an interaction term between age and sex. Bayesian logistic regression models were used to generate adjusted odds ratios (OR) for NO2 and PM2.5. pollutant models, adjusting for neighborhood income, age, sex, and an interaction between age and sex. We also examined models stratified for First-Nations (FN) and non-FN subgroups. Results Residents that were female and/or aged > 45 had a greater probability of being a SARD case, with the highest OR estimates for older females. Independently, the odds of being a SARDs case increased with PM2.5 levels, but the results were inconclusive for NO2. The results stratified by FN and Non-FN groups were not distinctly different. Conclusion In this urban Canadian sample, adjusting for demographics, exposure to PM2.5 was associated with an increased risk of SARDs. The results for NO2 were inconclusive. PMID:25988990

    The aim of this study was to investigate the condition of the temporomandibular joint (TMJ) in patients with different rheumatic diseases, and report correlations between the clinical, radiographic and magnetic resonance imaging (MRI) findings. The 67 patients were divided into four groups: 16 with rheumatoid arthritis (RA), 15 with mixed connective tissue disease (MCTD), 18 with ankylosing spondylitis (AS) and 18 with spondyloarthropathy (SPA). They were clinically examined, and panoramic tomography, lateral panoramic radiography and MRI of the TMJ were performed. MRI showed reduced articular cartilage in 25% (4/16) of RA, 0% (0/15) of MCTD, 17% (3/18) of AS and 17% (3/18) of SPA patients. Condylar changes included erosion, osteophytes and abnormal shape. Disc alterations included perforation, abnormal anterior position and decreased movement. These abnormalities were most frequent in RA patients, and least frequent in MCTD and SPA patients. Crepitation and reduced maximum opening of the mouth correlated with abnormalities of the disc and articular cartilage as shown by MRI. Severe condylar erosion in panoramic tomograms significantly correlated with MRI findings of condylar erosion (P<0.01), diminished thickness of condylar cartilage, abnormal condylar shape, and abnormal shape of the temporal surface of the TMJ (P< or =0.001). The presence of crepitation, limited mandibular movement and/or pain on movement of the jaw often indicated structural damage to the TMJ. Panoramic radiographs provide an alternative method to MRI but, to obtain a more detailed anatomic picture, MRI is recommended for patients with acute unexplained pain or as part of preoperative work up. A panoramic recording is not indicated when MRI is planned. PMID:17052893

    Inflammatory joint disorders (IJD), including rheumatoid arthritis (RA), ankylosing spondylitis (ASp) and psoriatic arthritis (PsA), are prevalent conditions worldwide with a considerable burden on healthcare systems. IJD are associated with increased cardiovascular (CV) disease-related morbidity and mortality. In this review, we present an overview of the literature. Standardised mortality ratios are increased in IJD compared with the general population, that is, RA 1.3-2.3, ASp 1.6-1.9 and PsA 0.8-1.6. This premature mortality is mainly caused by atherosclerotic events. In RA, this CV risk is comparable to that in type 2 diabetes. Traditional CV risk factors are more often present and partially a consequence of changes in physical function related to the underlying IJD. Also, chronic systemic inflammation itself is an independent CV risk factor. Optimal control of disease activity with conventional synthetic, targeted synthetic and biological disease-modifying antirheumatic drugs decreases this excess risk. High-grade inflammation as well as anti-inflammatory treatment alter traditional CV risk factors, such as lipids. In view of the above-mentioned CV burden in patients with IJD, CV risk management is necessary. Presently, this CV risk management is still lacking in usual care. Patients, general practitioners, cardiologists, internists and rheumatologists need to be aware of the substantially increased CV risk in IJD and should make a combined effort to timely initiate CV risk management in accordance with prevailing guidelines together with optimal control of rheumatic disease activity. CV screening and treatment strategies need to be implemented in usual care. PMID:26888573

    This study aimed to clarify changes in the prevalence of rheumatic diseases in Shantou, China, in the past 3 decades and validate whether stair-climbing is a risk factor for knee pain and knee osteoarthritis (KOA). The World Health Organization-International League Against Rheumatism Community Oriented Program for Control of Rheumatic Diseases (COPCORD) protocol was implemented. In all, 2337 adults living in buildings without elevators and 1719 adults living in buildings with elevators were surveyed. The prevalence of rheumatic pain at any site and in the knee was 15.7% and 10.2%, respectively; both types of pain had a significantly higher incidence in residents of buildings without elevators than was reported by people who lived in buildings with elevators (14.9% vs. 10.6% and 11.32% vs. 8.82%, respectively) (both P < 0.0001). The prevalence of rheumatic pain in the neck, lumbar spine, shoulder, elbow, and foot was 5.6%, 4.5%, 3.1%, 1.4%, and 1.8%, respectively; these findings were similar to the data from the 1987 rural survey, but were somewhat lower than data reported in the urban and suburban surveys of the 1990s, with the exception of neck and lumbar pain. The prevalence of KOA, gout, and fibromyalgia was 7.10%, 1.08%, and 0.07%, respectively, and their prevalence increased significantly compared with those in previous studies from the 20th century. There were no significant differences in the prevalence of rheumatoid arthritis (RA) (0.35%) or ankylosing spondylitis (AS) (0.31%) compared to that reported in prior surveys. The prevalence of KOA was higher in for residents of buildings without elevators than that in those who had access to elevators (16–64 years, 5.89% vs. 3.95%, P = 0.004; 16->85 years, 7.64% vs. 6.26%, P = 0.162). The prevalence of RA and AS remained stable, whereas that of KOA, gout, and fibromyalgia has increased significantly in Shantou, China, during the past 3 decades. Stair-climbing might be an important risk factor for knee pain and

    Objective To study the prevalence of rheumatic heart disease (RHD) in schools (locally referred to as ‘daaras’) located in the city of Dakar and its suburbs using both clinical examination and echocardiography. Methods This is a cross-sectional study conducted from 9 August to 24 December 2011 involving 2019 pupils, aged between 5 and 18 years selected from the 16 ‘daaras’ of the Academic Inspectorate (Inspection d'Académie) of the city of Dakar and its suburbs. Anamnestic, clinical and echocardiographic data were collected and entered into a questionnaire designed for the study. The World Heart Federation criteria for echocardiographic diagnosis were used to diagnose RHD. p<0.05 was considered statistically significant in bivariate analysis. Results About 60.1% of the pupils were men and the mean age was 9.7±3.3 years. 10 cases of definite RHD were detected, prevalence being 4.96 per 1000 (95% CI 2.4 to 9.1). This prevalence was five times higher with echocardiographic screening compared with clinical screening. 23 cases (11.4 per 1000) of borderline forms were detected. The populations at risk of definite RHD identified in our study were children over 14 years (p<0.001), those with recurrent sore throat (p=0.003) and those residing in the suburbs of the city of Dakar (p<0.001). Conclusion Our study shows a relatively high prevalence of RHD. Reducing its prevalence should focus on the implementation of appropriate policies, targeting at-risk populations and focusing on raising awareness and early detection.

    Aims The World Heart Federation (WHF) guidelines for rheumatic heart disease (RHD) are designed for a standard portable echocardiography (STAND) machine. A recent study in a tertiary care centre demonstrated that they also had good sensitivity and specificity when modified for use with handheld echocardiography (HAND). Our study aimed to evaluate the performance of HAND for early RHD diagnosis in the setting of a large-scale field screening. Methods and results STAND was performed in 4773 children in Gulu, Uganda, with 10% randomly assigned to also undergo HAND. Additionally, any child with mitral or aortic regurgitation also underwent HAND. Studies were performed by experienced echocardiographers and blindly reviewed by cardiologists using 2012 WHF criteria, which were modified slightly for HAND—due to the lack of spectral Doppler capability. Paired echocardiograms were performed in 1420 children (mean age 10.8 and 53% female), resulting in 1234 children who were normal, 133 who met criteria for borderline RHD, 47 who met criteria for definite RHD, and 6 who had other diagnoses. HAND had good sensitivity and specificity for RHD detection (78.9 and 87.2%, respectively), but was most sensitive for definite RHD (97.9%). Inter- and intra-reviewer agreement ranged between 66–83 and 71.4–94.1%, respectively. Conclusions HAND has good sensitivity and specificity for diagnosis of early RHD, performing best for definite RHD. Protocols for RHD detection utilizing HAND will need to include confirmation by STAND to avoid over-diagnosis. Strategies that evaluate simplified screening protocols and training of non-physicians hold promise for more wide spread deployment of HAND-based protocols. PMID:25564396

    Background Among patients with rheumatic heart disease (RHD), 45% to 60% present with atrial fibrillation (AF), which is associated with increased rates of thromboembolism, heart failure, and even death. The bipolar radiofrequency ablation (BRFA) combining with mitral valve procedure has been adopted in patients of AF associated with RHD, but evaluations about its effectiveness are still limited. Methods A total of 87 patients with RHD and long persistent AF who had accepted mitral valve replacement concomitant with BRFA were studied. Clinical data were collected to analyze the midterm results of BRFA and evaluate its efficiency. Univariate and multivariate analyses were used to identify the independent factors associated with late AF recurrence. Results Sixty-six (75.9%) patients maintained sinus rhythm after a mean follow-up of 13.4 ± 5.2 months. Late AF recurrence had been detected in 21 (24.1%) patients, 11 (12.6%) patients were confirmed to be AF, 8 (9.2%) patients were atrial flutter and 2 (2.3%) patients were junctional rhythm. In Multivariate logistic regression analysis, body mass index (BMI) (OR = 1.756, 95% CI = 1.289–2.391, p = 0.000) and early AF recurrence (OR = 5.479, 95% CI = 1.189–25.254, p = 0.029) were independent predictors of late AF recurrence. In addition, left ventricular ejection fraction (LVEF) and New York Heart Association class showed a greater improvement in patients who maintained sinus rhythm than those who experienced late AF recurrence. Conclusion BRFA is an effective technique for the treatment of long persistent AF associated with RHD during mitral valve replacement. The BMI and early AF recurrence are independent predictors for late AF recurrence. Patients with long-term restoration of sinus rhythm experienced a greater improvement of left ventricular function after BRFA. PMID:26960188

    Sphingolipids are ubiquitous building blocks of eukaryotic cell membranes. Progress in our understanding of sphingolipid metabolism, state-of-the-art sphingolipidomic approaches and animal models have generated a large body of evidence demonstrating that sphingolipid metabolites, particularly ceramide and sphingosine-1-phosphate, are signalling molecules that regulate a diverse range of cellular processes that are important in immunity, inflammation and inflammatory disorders. Recent insights into the molecular mechanisms of action of sphingolipid metabolites and new perspectives on their roles in regulating chronic inflammation have been reported. The knowledge gained in this emerging field will aid in the development of new therapeutic options for inflammatory disorders. PMID:24899305

    The group A streptococcus, Streptococcus pyogenes, and its link to autoimmune sequelae, has acquired a new level of understanding. Studies support the hypothesis that molecular mimicry between the group A streptococcus and heart or brain are important in directing immune responses in rheumatic fever. Rheumatic carditis, Sydenham chorea and a new group of behavioral disorders called pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections are reviewed with consideration of autoantibody and T cell responses and the role of molecular mimicry between the heart, brain and group A streptococcus as well as how immune responses contribute to pathogenic mechanisms in disease. In rheumatic carditis, studies have investigated human monoclonal autoantibodies and T cell clones for their crossreactivity and their mechanisms leading to valve damage in rheumatic heart disease. Although studies of human and animal sera from group A streptococcal diseases or immunization models have been crucial in providing clues to molecular mimicry and its role in the pathogenesis of rheumatic fever, study of human monoclonal autoantibodies have provided important insights into how antibodies against the valve may activate the valve endothelium and lead to T cell infiltration. Passive transfer of anti-streptococcal T cell lines in a rat model of rheumatic carditis illustrates effects of CD4+ T cells on the valve. Although Sydenham chorea has been known as the neurological manifestation of rheumatic fever for decades, the combination of autoimmunity and behavior is a relatively new concept linking brain, behavior and neuropsychiatric disorders with streptococcal infections. In Sydenham chorea, human mAbs and their expression in transgenic mice have linked autoimmunity to central dopamine pathways as well as dopamine receptors and dopaminergic neurons in basal ganglia. Taken together, the studies reviewed provide a basis for understanding streptococcal sequelae and

    Increasing numbers of adolescents are being diagnosed with Crohn's disease or ulcerative colitis, the two main subtypes of inflammatory bowel disease. These young people face many short- and long-term challenges; one or more medical therapies may be required indefinitely; their disease may have great impact, in terms of their schooling and social activities. However, the management of adolescents with one of these incurable conditions needs to encompass more than just medical therapies. Growth, pubertal development, schooling, transition, adherence, and psychological well-being are all important aspects. A multidisciplinary team setting, catering to these components of care, is required to ensure optimal outcomes in adolescents with inflammatory bowel disease. PMID:24729736

    Are rheumatic musculoskeletal diseases (RMSD) given their due recognition by the medical fraternity and policy makers in India today? Focus on lifestyle diseases has taken away the importance of morbidity caused by musculoskeletal pain, which is one of the commonest ailments in the community. Poor awareness in general regarding the upcoming field of rheumatology and lack of proper data regarding these diseases in the country are the primary causes for this debacle. The epidemiology of RMSD in the country is fast changing, especially in the wake of viral epidemics, which leave their mark for months and years together. This view point emphasizes the burden of RMSD by highlighting the findings of two Community Oriented Programme for the Control of Rheumatic Diseases studies conducted to study the prevalence of RMSD in rural communities in the southern state of Kerala, which inadvertently captured the burden of RMSD following Chikungunya viral epidemics in the regions. Both the studies have reported a high prevalence of RMSD following the epidemics. The value of including RMSD in a national programme to combat the morbidity caused and to improve the health related quality of life of patients has been stressed upon, in the background of altering epidemiology of these disorders in the country.

    Background: Rheumatic heart disease (RHD) is a global cause of early heart failure. Early RHD is characterized by valvar regurgitation, leading to ventricular distention and possible elaboration of amino-terminal pro-brain natriuretic peptide (NT-proBNP). We investigated the ability of NT-proBNP to distinguish cases of latent RHD detected by echocardiographic screening from the controls. Materials and Methods: Ugandan children (N = 44, 36% males, mean age: 12 ± 2 years) with latent RHD (cases) and siblings (controls) by echocardiography were enrolled. Cases and controls were matched for age and sex, and they had normal hemoglobin (mean: 12.8 mg/dL). Children with congenital heart disease, pregnancy, left ventricular dilation or ejection fraction (EF) below 55%, or other acute or known chronic health conditions were excluded. RHD cases were defined by the World Heart Federation (WHF) 2012 consensus guideline criteria as definite. Controls had no echocardiography (echo) evidence for RHD. At the time of echo, venous blood samples were drawn and stored as serum. NT-proBNP levels were measured using sandwich immunoassay. Paired t-tests were used to compare NT-proBNP concentrations including sex-specific analyses. Results: The mean NT-proBNP concentration in the cases was 105.74 ± 67.21 pg/mL while in the controls, it was 86.63 ± 55.77 pg/mL. The cases did not differ from the controls (P = 0.3). In sex-specific analyses, male cases differed significantly from the controls (158.78 ± 68.82 versus 76 ± 42.43, P = 0.008). Female cases did not differ from the controls (75.44 ± 45.03 versus 92.30 ± 62.35 respectively, P = 0.4). Conclusion: Serum NT-proBNP did not distinguish between latent RHD cases and the controls. Sex and within-family exposures may confound this result. More investigation into biomarker-based RHD detection is warranted. PMID:27212845

    This study aimed to estimate the prevalence of musculoskeletal (MSK) disorders and rheumatic diseases in the Chontal and Mixtec indigenous communities in the state of Oaxaca, Mexico, using the Community-Oriented Program for the Control of Rheumatic Diseases (COPCORD) methodology. After cross-culturally validating the COPCORD questionnaire for these communities, we conducted a cross-sectional, analytical, community-based census study using a house-to-house method. Positive cases of MSK disorders were assessed by primary care physicians and rheumatologists. The study population included participants aged ≥18 years from the indigenous communities of San Antonio Huitepec and San Carlos Yautepec. A total of 1061 persons participated in the study. Mean age was 46.9 years (standard deviation 19.9; age range 18-97 years); 642 (60.5 %) were women; 483 participants (45.5; 42.4-48.5 %) had MSK pain in the previous 7 days. Diagnoses were back pain 170 (16.0 %; 95 % confidence interval [CI] 13.8-18.3); osteoarthritis 157 (14.7 %; 95 % CI 12.7-17.0); rheumatic regional pain syndrome 53 (4.9 %; 95 % CI 3.7-6.4); rheumatoid arthritis 4 (0.3 %; 95 % CI 0.1-0.9); dermatomyositis 1 (0.09 %; 95 % CI 0.0-0.5); ankylosing spondylitis 1 (0.09 %; 95 % CI 0.0-0.5); systemic lupus erythematosus 1 (0.09 %; 95 % CI 0.02-0.5); and gout 1 (0.09 %; 95 % CI 0.0-0.5). 53.2 % had not received medical treatment for their disease. The prevalence of MSK disorders in indigenous communities in the Mixtec and Chontal regions is very high. The most common rheumatic diseases found were back pain and osteoarthritis. A high percentage of participants had not received medical care. PMID:26689797

    The aim of the study was to determine the prevalence of musculoskeletal disorders and rheumatic diseases in an urban community in Venezuela. We conducted a cross-sectional, community-based study using the COPCORD (Community Oriented Program for Control of Rheumatic Diseases) methodology in subjects older than 18 years. Positive cases were evaluated by rheumatologists. We surveyed 3,973 individuals (1,606 males and 2,367 females), with a mean age of 43.7 years (standard deviation (SD) 17.6). Mean duration of education was 8.9 years (SD 3.7), 79.2 % had a monthly income of < US$569, and 46.4 % were working. Excluding trauma, the prevalence of pain in the 7 days prior to interview was 19.9 % (95 % confidence interval (CI) 18.7-21.2 %). Mean pain intensity on a visual analog scale was 6.3 (SD 2.2), and 30.1 % (95 % CI 28.7-31.6 %) had a history of pain. Respondents reported pain in the knees, back, hands, shoulders, and ankles in the last 7 days; 4.7 % described current functional limitation, with 16.5 % reporting limitations in the past. Regarding treatment, 23.9 % received medication, 6.4 % received physical therapy, and 2.6 % received alternative treatment. The main diagnoses were osteoarthritis in 15.0 % (95 % CI 13.9-16.1 %), rheumatic regional pain syndromes in 6.3 % (95 % CI 5.5-7.1 %), back pain in 2.8 % (95 % CI 2.3-3.4 %), rheumatoid arthritis in 0.4 % (95 % CI 0.2-0.6 %), crystal arthropathy in 0.3 % (95 % CI 0.1-0.5 %), fibromyalgia in 0.2 % (95 % CI 0.1-0.4 %), and systemic lupus erythematosus in 0.07 % (95 % CI 0.01-0.2 %). The prevalence of musculoskeletal disorders was 22.4 %, and the most prevalent disease was osteoarthritis. Pain, in which a patient is receiving treatment for musculoskeletal disorders, and physical disability were associated with the presence of a rheumatic disease. PMID:24924602

    Determination of anti-citrullinated peptide antibodies (ACPA) plays a relevant role in the diagnosis of rheumatoid arthritis (RA). To date, it is still unclear if the use of several tests for these autoantibodies in the same patient offers additional value as compared to performing only one test. Therefore, we evaluated the performance of using two assays for ACPA: second-generation anti-citrullinated cyclic peptides antibodies (anti-CCP2) and anti-mutated citrullinated vimentin (anti-MCV) antibodies for the diagnosis of RA. We compared three groups: RA (n = 142), chronic inflammatory disease (CIRD, n = 86), and clinically healthy subjects (CHS, n = 56) to evaluate sensitivity, specificity, predictive values, and likelihood ratios (LR) of these two assays for the presence of RA. A lower frequency of positivity for anti-CCP2 was found in RA (66.2%) as compared with anti-MCV (81.0%). When comparing RA versus other CIRD, sensitivity increased when both assays were performed. This strategy of testing both assays had high specificity and LR+. We conclude that adding the assay of anti-MCV antibodies to the determination of anti-CCP2 increases the sensitivity for detecting seropositive RA. Therefore, we propose the use of both assays in the initial screening of RA in longitudinal studies, including early onset of undifferentiated arthritis. PMID:25025037

    This study aimed to estimate the prevalence of musculoskeletal disorders and rheumatic diseases in indigenous Maya-Yucateco communities using Community-Oriented Program for Control of Rheumatic Diseases (COPCORD) methodology. The study population comprised subjects aged ≥18 years from 11 communities in the municipality of Chankom, Yucatan. An analytical cross-sectional study was performed, and a census was used. Subjects positive for musculoskeletal (MSK) pain were examined by trained physicians. A total of 1523 community members were interviewed. The mean age was 45.2 years (standard deviation (SD) 17.9), and 917 (60.2 %) were women. Overall, 592 individuals (38.8 %; 95 % CI 36.3-41.3 %) had experienced MSK pain in the last 7 days. The pain intensity was reported as "strong" to "severe" in 43.4 %. The diagnoses were rheumatic regional pain syndromes in 165 (10.8 %; 95 % CI 9.4-12.5), low back pain in 153 (10.0 %; 95 % CI 8.5-11.6), osteoarthritis in 144 (9.4 %; 95 % CI 8.0-11.0), fibromyalgia in 35 (2.2 %; 95 % CI 1.6-3.1), rheumatoid arthritis in 17 (1.1 %; 95 % CI 0.6-1.7), undifferentiated arthritis in 8 (0.5 %; 95 % CI 0.2-0.8), and gout in 1 (0.06 %; 95 % CI 0.001-0.3). Older age, being female, disability, and physically demanding work were associated with a greater likelihood of having a rheumatic disease. In conclusion, MSK pain and rheumatic diseases were highly prevalent. The high impact of rheumatic diseases on daily activities in this indigenous population suggests the need to organize culturally-sensitive community interventions for the prevention of disabilities caused by MSK disorders and diseases.

Previous studies have implicated IL-18 in the pathogenesis of various diseases. However, it is not well understood biologic activities of IL-18 in the diverse skin diseases. Here, we have reviewed the expression and function of IL-18 in skin diseases including inflammatory diseases. This article provides an evidence-based understanding of the role of IL-18 in skin diseases and its relationship with disease activities. PMID:26690141

    The first gold-mercaptopropionic acid-polyethylenimine composite based electrochemical DNA biosensor was fabricated for the early detection of Streptococcus pyogenes infection in humans causing rheumatic heart disease (heart valve damage). No biosensor is available for the detection of rheumatic heart disease (RHD). Therefore, the mga gene based sensor was developed by the covalent immobilization of a 5'-carboxyl modified single stranded DNA probe onto the gold composite electrode. The immobilized probe was hybridized with the genomic DNA (G-DNA) of S. pyogenes from throat swabs and the electrochemical response was measured by cyclic voltammetry (CV), differential pulse voltammetry (DPV) and electrochemical impedance (EI). Covalent immobilization of the probe onto the gold composite and its hybridization with G-DNA was characterized by FTIR and SEM. The sensitivity of the sensor was 110.25 μA cm(-2) ng(-1) with DPV and the lower limit of detection was 10 pg per 6 μL. The sensor was validated with patient throat swab samples and results were compared with available methods. The sensor is highly specific to S. pyogenes and can prevent damage to heart valves by the early detection of the infection in only 30 min. PMID:24875529

    Objective: To investigate patients' and occupational physicians' satisfaction with the quality of a vocational rehabilitation programme for maintaining work ability in chronic rheumatic diseases. Methods: The vocational rehabilitation programme was developed for patients with rheumatic diseases and consisted of systematic assessment of the problems at work and the development of individual solutions. The programme was run by a multidisciplinary team comprising a rheumatologist, a social worker, a physical and occupational therapist, and a psychologist. Satisfaction ratings were measured using a multidimensional questionnaire involving a rating scale (0–10) and a structured telephone interview. Results: 59 of the 65 patients who participated in the programme (91%) completed the questionnaire. Patients were most satisfied with the interpersonal approach and professional knowledge, and least satisfied with the waiting time for the final report and the practical application of the given advice. Mean satisfaction score was 7.3 (SD 1.0). Twenty eight of the occupational physicians involved were interviewed. They were satisfied with the programme overall; 21 (75%) stated that their role in the vocational rehabilitation process could be defined more clearly, and they would appreciate more contact with the team members, preferably in the early phases. Conclusions: Patients' and occupational physicians' satisfaction with a multidisciplinary vocational rehabilitation programme was good. Areas for improvement mainly concerned the speed of the process and the communication between team members and occupational physicians. PMID:15082488

    Kidney transplant recipients frequently suffer from skin infections and malignancies, possibly due to the effects of long-term immunosuppressive therapy. While the relationships between immunosuppression and these pathological conditions have been widely investigated, little is known about the relative incidence and characteristics of inflammatory skin diseases in this type of patient. In this study, we analyze the incidence of a number of inflammatory cutaneous diseases in a cohort of patients who underwent kidney transplantation. Although our study shows a relatively low incidence of these pathologies in transplanted patients—in agreement with the general action of immunosuppressant therapies in reducing inflammation—we scored a different efficacy of the various immunosuppressive regimens on inflammatory and autoimmune skin diseases. This information can be key for designing immunosuppressive regimens and devising accurate follow-up protocols. PMID:27548160

    Coronary artery disease (CAD) is one of the most common manifestations of atherosclerosis. Inflammation is considered one of the major processes that contribute to atherogenesis. Inflammation plays an important role not only on the initiation and progression of atherosclerosis but also on plaque rupture, an event that leads to acute vascular events. Various biomarkers express different pathways and pathophysiologic mechanisms of cardiovascular disease, and inflammatory biomarkers express different parts of the atherogenic process, regarding the initiation and progression of atherosclerosis or the destabilization of the atherosclerotic plaque. Therefore, inflammatory biomarkers may prove to be useful in the detection, staging, and prognosis of patients with CAD. Furthermore, the fact that inflammatory processes are essential steps in the course of the disease offers future therapeutic targets for the interruption of the atherogenic process or for the management of acute events.

    The enzyme indoleamine 2,3-dioxygenase 1 (IDO1) finely regulates both innate and adaptive immune responses through the degradation of the essential amino acid tryptophan into kynurenine and other downstream metabolites, which suppress effector T-cell function and promote the differentiation of regulatory T cells. A novel role for IDO1 as a signaling molecule and a modifier of innate inflammatory responses is now emerging. In particular, IDO1 can either support or antagonize inflammation in a context- and tissuedependent manner. Studies in experimental arthritis have unravelled a previously unappreciated role for IDO in controlling B-cell activation and autoantibody production. IDO dysregulation has been documented in patients with systemic lupus erythematosus, systemic sclerosis and Sjogren's syndrome, as well as in severe sepsis and chronic kidney disease. This article summarizes the contribution of IDO to the pathophysiology of inflammatory/autoimmune disorders, and discusses whether strategies to restore metabolic equilibrium in the kynurenine pathway might be pursued in diseases states such as rheumatoid arthritis and systemic sclerosis.

    Interleukin (IL)-9 is a 28-30 kDa monomeric glycosylated polypeptide belonging to the IL-7/IL-9 family of proteins that bind to a composite receptor consisting of the private receptor IL-9R and the IL-2 receptor, gamma (IL-2RG), a common gamma subunit shared by the receptors of many different cytokines. The IL-9R is expressed widely and IL-9 impacts a number of effector cells, such as effector T cells, B cells, innate lymphoid cells, mast cells, polymorphonuclear cells, epithelial cells and smooth muscle cells, playing an important role in regulating inflammatory immunity. The critical role of IL-9 in promoting cellular and humoral immune responses makes it an important focus of potential therapeutic interventions. Recently, a defined subset of T helper type cells, Th9 cells, has been identified by the potent production of IL-9. The involvement of the Th9 cell subset has been described in many types of inflammatory diseases, namely atopic diseases, helminth infections, experimental autoimmune encephalomyelitis and ulcerative colitis. In this review, we summarize the IL-9 biological activities, highlighting roles for IL-9 and Th9 cells in rheumatoid and psoriatic arthritis, systemic vasculitis, systemic lupus erythematosus and systemic sclerosis.

    In inflammatory bowel disease it is important that patients understand their condition since this helps to improve long-term management of the disease. The aim of this study was to assess the information given to patients with inflammatory bowel disease about their condition, its treatment and the National Association for Colitis and Crohn's disease. Two surveys were performed, using anonymous questionnaires. One was of all association members in north-east England, the other was a sample of patients attending medical outpatients. The surveys showed that more patients heard of the National Association for Colitis and Crohn's disease from the media than from medical sources. Of patients seen in medical clinics, 75% would welcome more information about their disease. In four of the six participating centres less than half the patients had been told about the existence of a patients' association. There was considerable variation in the instructions on what action to take in the event of a relapse. These findings suggest that the opportunity offered by out-patient clinics to educate and inform patients is often wasted. Clinicians often neglect to mention the National Association for Colitis and Crohn's disease, especially to patients with long-standing disease. A higher priority should be given to providing patients with appropriate information on inflammatory bowel disease. Three simple audit standards for the organisation of outpatient clinic information are proposed. PMID:9131520

    Through a comprehensive review of the recent findings on rheumatic fever, we intend to propose a new physiopathologic model for this disease. A Medline search was performed for all articles containing the terms rheumatic fever or rheumatic heart disease in title or abstract from 1970 to 2011. Best evidence qualitative technique was used to select the most relevant. The scientific interest on rheumatic fever has notably diminished throughout the twentieth century as evidenced by the comparison of the proportion of articles in which RF was a subject in 1950 (0.26%) and today (0.03%) [Pubmed]. However, RF remains a major medical and social problem in the developing world and in the so-called hotspots, where it still causes around 500.000 deaths each year, not too different from the pre-antibiotic era. The role of genetic factors in RF susceptibility is discussed. Familiar aggregation, similarity of disease patterns between siblings, identical twin, and HLA correlation studies are evidence for a genetic influence on RF susceptibility. The suspect-involved genes fall mainly into those capable of immunologic mediation. Molecular mimicry explains the triggering of RF, but an intense and sustained inflammation is needed to cause sequels. Also, RF patients vary greatly in terms of symptoms. It is likely that a genetic background directing immune response towards a predominantly Th1 or Th2 pattern contributes to these features. The recent findings on rheumatic fever provide important insight on its physiopathology that helps understanding this prototype post-infectious autoimmune disease giving insights on other autoimmune conditions.

    Thromboembolic events represent a major cause of morbidity and mortality in patients with inflammatory bowel disease and they may occur both at the gastrointestinal tract and at extraintestinal sites. This study aimed to examine the alterations in coagulation parameters involved at different steps of hemostasis in patients with Crohn’s disease and ulcerative colitis, in comparison with healthy individuals. Fifty-one patients with inflammatory bowel disease and 26 healthy controls were included in this study. Plasma levels of PT, APTT, AT III, plasminogen, fibrinogen, D-dimer, factor V, factor VIII, protein C, protein S, and APCR were measured and factor V Leiden mutation was examined in both patients and controls. Two patients with ulcerative colitis had a history of previous thromboembolic event. Inflammatory bowel disease was associated with significantly higher levels of fibrinogen, PT, factor V, factor VIII, plasminogen and thrombocyte. Protein S, fibrinogen, plasminogen and thrombocyte levels were associated with disease activity, depending on the type of the disease (Crohn’s disease or ulcerative colitis). The coagulation abnormalities detected in this study seems to be a secondary phenomena resulting from the disease process, which is more likely to be associated with a multitude of factors rather than a single abnormality.

    Mesenchymal stem cells (MSCs) are emerging as a therapeutic modality in various inflammatory disease states. A number of ongoing randomized Phase I/II clinical trials are evaluating the effects of allogeneic MSC infusion in patients with multiple sclerosis, graft-versus-host disease, Crohn's disease, and severe chronic myocardial ischemia. MSCs are also being considered as a potential therapy in patients with inflammatory lung diseases. Several studies, including our own, have demonstrated compelling benefits from the administration of MSCs in animal models of lung injury. These studies are leading to growing interest in the therapeutic use of MSCs in inflammatory lung diseases. In this Review, we describe how the immunoregulatory effects of MSCs can confer substantial protection in the setting of lung diseases such as acute lung injury, chronic obstructive pulmonary disease, asthma, and pulmonary hypertension. We also address potential pitfalls related to the therapeutic use of MSCs in fibrotic lung diseases such as idiopathic pulmonary fibrosis. In addition, we identify emerging areas for MSC- based therapies in modulating oxidative stress and in attenuating inflammation in alcohol-related acute lung injury. PMID:19352305

    Abstract: Surgical management of inflammatory bowel disease is a challenging endeavor given infectious and inflammatory complications, such as fistula, and abscess, complex often postoperative anatomy, including adhesive disease from previous open operations. Patients with Crohn's disease and ulcerative colitis also bring to the table the burden of their chronic illness with anemia, malnutrition, and immunosuppression, all common and contributing independently as risk factors for increased surgical morbidity in this high-risk population. However, to reduce the physical trauma of surgery, technologic advances and worldwide experience with minimally invasive surgery have allowed laparoscopic management of patients to become standard of care, with significant short- and long-term patient benefits compared with the open approach. In this review, we will describe the current state-of the-art for minimally invasive surgery for inflammatory bowel disease and the caveats inherent with this practice in this complex patient population. Also, we will review the applicability of current and future trends in minimally invasive surgical technique, such as laparoscopic “incisionless,” single-incision laparoscopic surgery (SILS), robotic-assisted, and other techniques for the patient with inflammatory bowel disease. There can be no doubt that minimally invasive surgery has been proven to decrease the short- and long-term burden of surgery of these chronic illnesses and represents high-value care for both patient and society.

    Introduction Rheumatic diseases are among the most common and debilitating health problems in the United States. These diseases are chronic, can result in severe decrements of physical and psychosocial functioning and affect patients' overall quality of life. A consensus regarding the best patient outcomes to be measured in randomized, controlled trials and prospective natural history studies is essential to provide best estimates of efficacy and safety of interventions across diverse patient populations. Methods Face-to-face English- and Spanish-language cognitive interviews were conducted among urban Hispanic and African American patients with rheumatic disease to develop a questionnaire booklet. Six measures validating patient-reported outcomes were included: the Arthritis Self-Efficacy Scale, the Stanford Health Assessment Questionnaire Disability Index, the Wong-Baker Faces Pain Scale, the Short Acculturation Scale, the Center for Epidemiologic Studies Depression Scale and the Inventory of Complementary and Alternative Medicine Practices. A sample of patients (n = 15) attending the National Institute of Arthritis and Musculoskeletal and Skin Diseases Community Health Center participated in the initial interviews. Revised measures were further tested for reliability in a separate sample of patients (n = 109) upon enrollment at the health center. Results Cognitive interviews provided feedback for questionnaire modifications and methods to enhance content validity and data quality, including discarding redundant questions, providing visual aids and concrete examples when appropriate and increasing the use of racially and ethnically concordant interviewers. The cognitive interviews further elucidated that some contextual assumptions and language usage in the original questionnaires may not have taken each respondent's environmental and sociocultural context into consideration. Internal reliability for previously tested measures remained high (Cronbach's α = 0

    Increasing numbers of adolescents are being diagnosed with Crohn’s disease or ulcerative colitis, the two main subtypes of inflammatory bowel disease. These young people face many short- and long-term challenges; one or more medical therapies may be required indefinitely; their disease may have great impact, in terms of their schooling and social activities. However, the management of adolescents with one of these incurable conditions needs to encompass more than just medical therapies. Growth, pubertal development, schooling, transition, adherence, and psychological well-being are all important aspects. A multidisciplinary team setting, catering to these components of care, is required to ensure optimal outcomes in adolescents with inflammatory bowel disease. PMID:24729736

    Central nervous system (CNS) complications or manifestations of inflammatory bowel disease deserve particular attention because symptomatic conditions can require early diagnosis and treatment, whereas unexplained manifestations might be linked with pathogenic mechanisms. This review focuses on both symptomatic and asymptomatic brain lesions detectable on imaging studies, as well as their frequency and potential mechanisms. A direct causal relationship between inflammatory bowel disease (IBD) and asymptomatic structural brain changes has not been demonstrated, but several possible explanations, including vasculitis, thromboembolism and malnutrition, have been proposed. IBD is associated with a tendency for thromboembolisms; therefore, cerebrovascular thromboembolism represents the most frequent and grave CNS complication. Vasculitis, demyelinating conditions and CNS infections are among the other CNS manifestations of the disease. Biological agents also represent a risk factor, particularly for demyelination. Identification of the nature and potential mechanisms of brain lesions detectable on imaging studies would shed further light on the disease process and could improve patient care through early diagnosis and treatment.

    Inflammatory bowel disease (IBD), including Crohn disease and ulcerative colitis, is characterized by chronic intestinal inflammation due to a complex interaction of genetic determinants, disruption of mucosal barriers, aberrant inflammatory signals, loss of tolerance, and environmental triggers. Importantly, the incidence of pediatric IBD is rising, particularly in children younger than 10 years. In this review, we discuss the clinical presentation of these patients and highlight environmental exposures that may affect disease risk, particularly among people with a background genetic risk. With regard to both children and adults, we review advancements in understanding the intestinal epithelium, the mucosal immune system, and the resident microbiota, describing how dysfunction at any level can lead to diseases like IBD. We conclude with future directions for applying advances in IBD genetics to better understand pathogenesis and develop therapeutics targeting key pathogenic nodes. PMID:27168239

    Inflammatory bowel diseases are characterised by inflammation that compromises the integrity of the epithelial barrier. The intestinal epithelium is not only a static barrier but has evolved complex mechanisms to control and regulate bacterial interactions with the mucosal surface. Apical tight junction proteins are critical in the maintenance of epithelial barrier function and control of paracellular permeability. The characterisation of alterations in tight junction proteins as key players in epithelial barrier function in inflammatory bowel diseases is rapidly enhancing our understanding of critical mechanisms in disease pathogenesis as well as novel therapeutic opportunities. Here we give an overview of recent literature focusing on the role of tight junction proteins, in particular claudins, in inflammatory bowel diseases and inflammatory bowel disease associated colorectal cancer.

    Diarrhea is a common clinical feature of inflammatory bowel diseases and may be accompanied by abdominal pain, urgency, and fecal incontinence. The pathophysiology of diarrhea in these diseases is complex, but defective absorption of salt and water by the inflamed bowel is the most important mechanism involved. In addition to inflammation secondary to the disease, diarrhea may arise from a variety of other conditions. It is important to differentiate the pathophysiologic mechanisms involved in the diarrhea in the individual patient to provide the appropriate therapy. This article reviews microscopic colitis, ulcerative colitis, and Crohn's disease, focusing on diarrhea. PMID:22917170

    Anderson, J. A. D. (1971).Brit. J. industr. Med.,28, 103-121. Rheumatism in industry: a review. Information about causes, effects, and prevention of rheumatic disease among industrial workers lacks standardization, as shown by the literature in this field; one reason for this is that there are discrepancies about the range of diseases and syndromes which should be included under this heading. The Industrial Survey Unit of the Arthritis and Rheumatism Council defined a rheumatic complaint as musculo-skeletal pain not related to recent (i.e., within six weeks) trauma. A study by the Unit of the social and economic effects of rheumatism among 2 684 male employees from a range of manual occupations is considered in relation to the observations made by other investigators. Sickness absence (at present estimated to be about 29·8 million working days per annum in Britain) and premature retirement can be shown to result directly from rheumatic complaints, especially rheumatoid arthritis and disc disease; furthermore, there seems to be general agreement that sickness absence is more marked in heavy manual occupations than in light ones. However, the extent to which job changes ascribed to rheumatic complaints are in fact caused by them is more doubtful. Evidence supporting the view that occupational factors are related to the aetiology of some chronic rheumatic diseases is fairly strong. Chronic tenosynovitis, bursitis, osteoarthrosis, and, to a lesser extent, disc disease are among those in which such a relationship can be demonstrated; however, the reason why some men are more prone to develop these conditions than others working in similar jobs is still in doubt, suggesting that the aetiology is multifactorial. In other rheumatic diseases, notably rheumatoid arthritis, a fairly extensive study of the literature does not indicate any clear correlation between occupation and aetiology.

    Between July 1973 and October 1984, we performed proctectomy either as part of a primary proctocolectomy or as a secondary staged procedure in 388 patients with ulcerative colitis and in 39 patients with Crohn's disease. The proctectomies were performed using a two-team synchronous approach. An intersphincteric or perimuscular technique was employed. All perineal wounds were closed and drained by suction drainage and the pelvic peritoneum was closed in all cases. Two patients died in the early postoperative period, one from a pulmonary embolus and one from sepsis. Three patients had to be reexplored for postoperative hemorrhage, in all cases from a branch of the superior hemorrhoidal artery. Postoperative perineal hematoma developed in two patients and perineal abscess developed in four patients which necessitated opening of the perineal skin wound. Nonhealing of the perineal wound occurred in 3 of 388 patients with ulcerative colitis and in 5 of 39 patients with Crohn's disease. No perineal dehiscence or hernias were seen. Postoperatively, one man was permanently impotent and two had prolonged but temporary impotence. Three patients had retrograde ejaculation at last follow-up. PMID:3484910

    With an estimated 70 million Americans suffering, sleep disorders have become a global issue, and discovering their causes and consequences are the focus of many clinical research studies. Sleep is now also considered to be an important environmental and behavioral factor associated with the process of inflammation and the immune system. Increased sleepiness is considered part of the acute phase of response to tissue injury, and sleep loss activates inflammatory cytokines such as interleukin (IL)-1 and tumor necrosis factor (TNF)-α. Clinical studies in many immune-mediated diseases, such as systemic lupus erythematosus, rheumatoid arthritis, and ankylosing spondylitis, have revealed an association of sleep disturbances with disease activity. Recent research suggests that individuals with sleep abnormalities are also at greater risk of serious adverse health, economic consequences, and most importantly increased all-cause mortality. The importance of sleep in inflammatory bowel disease has recently gained attention with some published studies demonstrating the association of sleep disturbances with disease activity, subclinical inflammation, and risk of disease relapse. A comprehensive review of sleep physiology and its association with the immune system is provided here. Experimental and clinical studies exploring this relationship in inflammatory bowel disease are reviewed, and the clinical implications of this relationship and future directions for research are also discussed.

    Female genital tract microbiota play a crucial role in maintaining health. Disequilibrium of the microbiota has been associated with increased risk of pelvic infections. In recent years, culture-independent molecular techniques have expanded understanding of the composition of genital microbiota and the dynamic nature of the microbiota. There is evidence that upper genital tract may not be sterile and may harbor microflora in the physiologic state. The isolation of bacterial vaginosis-associated organisms in women with genital infections establishes a link between pelvic infections and abnormal vaginal flora. With the understanding of the composition of the microbiota in healthy and diseased states, the next logical step is to identify the function of the newly identified microbes. This knowledge will further expand our understanding of the causation of pelvic infections, which may lead to more effective prevention and treatment strategies. PMID:24390920

Awareness of the problems, some strengthening of the diagnostic criteria, and the evolution of the illness with time would serve to correct misdiagnosis. PMID:6946305

    2015-01-01

    Vitamin D deficiency has been recognized as an environmental risk factor for Crohn's disease since the early 80s. Initially, this finding was correlated with metabolic bone disease. Low serum 25-hydroxyvitamin D levels have been repeatedly reported in inflammatory bowel diseases together with a relationship between vitamin D status and disease activity. Subsequently, low serum vitamin D levels have been reported in various immune-related diseases pointing to an immunoregulatory role. Indeed, vitamin D and its receptor (VDR) are known to interact with different players of the immune homeostasis by controlling cell proliferation, antigen receptor signalling, and intestinal barrier function.

    Vitamin D deficiency has been recognized as an environmental risk factor for Crohn's disease since the early 80s. Initially, this finding was correlated with metabolic bone disease. Low serum 25-hydroxyvitamin D levels have been repeatedly reported in inflammatory bowel diseases together with a relationship between vitamin D status and disease activity. Subsequently, low serum vitamin D levels have been reported in various immune-related diseases pointing to an immunoregulatory role. Indeed, vitamin D and its receptor (VDR) are known to interact with different players of the immune homeostasis by controlling cell proliferation, antigen receptor signalling, and intestinal barrier function. Moreover, 1,25-dihydroxyvitamin D is implicated in NOD2-mediated expression of defensin-β2, the latter known to play a crucial role in the pathogenesis of Crohn's disease (IBD1 gene), and several genetic variants of the vitamin D receptor have been identified as Crohn's disease candidate susceptibility genes.

    Introduction of biological therapies have led to dramatic changes in the management of debilitating immune-mediated inflammatory bowel diseases (IBD) including ulcerative colitis and Crohn's disease. However, the long term use of these agents may be very expensive, placing a significant burden on National Healthcare Systems. The development of first biosimilar to infliximab, CT-P13 (Remsima; Celltrion Inc., Incheon, Korea and Inflextra; Hospiral, Lake Forest, Illinois, USA) has become another way to decrease the medical care cost and increase patient treatment option, but, actual equivalence of efficacy and safety of CT-P13 was investigated in rheumatic diseases only. The extrapolation of outcome from rheumatic trials to IBD and the interchangeability of CT-P13 with infliximab have come to be a matter of concern. Two recent retrospective studies reported the similarity of CT-P13 in terms of efficacy and safety. Infliximab biosimilars may be promising new treatment options for IBD patients, however, well-designed, prospective randomized non-inferiority trials should be needed to confidently integrate infliximab biosimilars into IBD treatment.

    Keratoconjunctivitis sicca, or dry eye, is a common ocular disease prompting millions of individuals to seek ophthalmological care. Regardless of the underlying etiology, dry eye has been shown to be associated with abnormalities in the pre-corneal tear film and subsequent inflammatory changes in the entire ocular surface including the adnexa, conjunctiva and cornea. Since the recognition of the role of inflammation in dry eye, a number of novel treatments have been investigated designed to inhibit various inflammatory pathways. Current medications that are used, including cyclosporine A, corticosteroids, tacrolimus, tetracycline derivatives and autologous serum, have been effective for management of dry eye and lead to measurable clinical improvement.

    Inflammatory bowel diseases (IBD) include ulcerative colitis and Crohn's disease. The immune response in ulcerative colitis is different from the Crohn's disease. Accumulating evidence suggests that IBD results from an inappropriate inflammatory response to intestinal microbes in a genetically susceptible host. Several immunoregulatory abnormalities have been reported in patients with IBD, including the ratio of proinflammatory (tumor necrosis factor alpha, IL-6, IL-1-β) to immunoregulatory cytokines (IL-10, TGF-β, IL-35) and selective activation of T-helper (Th) lymphocyte subsets (Th1, Th2, Th9, Th17, and regulatory T cells). The purpose of this review is to show the immunoregulatory pathways (regulatory cells and cytokines) involved in IBD published in recent years. PMID:26111210

    Zinc absorption was measured in 29 patients with inflammatory bowel disease and a wide spectrum of disease activity to determine its relationship to disease activity, general nutritional state, and zinc status. Patients with severe disease requiring either supplementary oral or parenteral nutrition were excluded. The mean 65ZnCl2 absorption, in the patients, determined using a 65Zn and 51Cr stool-counting test, 45 +/- 17% (SD), was significantly lower than the values, 54 +/- 16%, in 30 healthy controls, P less than 0.05. Low 65ZnCl2 absorption was related to undernutrition, but not to disease activity in the absence of undernutrition or to zinc status estimated by leukocyte zinc measurements. Mean plasma zinc or leukocyte zinc concentrations in patients did not differ significantly from controls, and only two patients with moderate disease had leukocyte zinc values below the 5th percentile of normal. In another group of nine patients with inflammatory bowel disease of mild-to-moderate severity and minimal nutritional impairment, 65Zn absorption from an extrinsically labeled turkey test meal was 31 +/- 10% compared to 33 +/- 7% in 17 healthy controls, P greater than 0.1. Thus, impairment in 65ZnCl2 absorption in the patients selected for this study was only evident in undernourished persons with moderate or severe disease activity, but biochemical evidence of zinc deficiency was uncommon, and clinical features of zinc depletion were not encountered.

    A switch from cell-mediated to humoral immunity (helper T 1 [Th1] to helper T 2 [Th2] shift) during gestation plays a key role in placental immune tolerance. As a result, skin diseases that are Th2 mediated often worsen, whereas skin diseases that are Th1 mediated often improve during gestation. Also, due to fluctuations in glandular activity, skin diseases involving sebaceous and eccrine glands may flare, whereas those involving apocrine glands may improve during pregnancy. Despite these trends, inflammatory and glandular skin diseases do not always follow the predicted pattern, and courses are often diverse. We review the gestational course of inflammatory skin diseases, such as atopic dermatitis (atopic eruption of pregnancy), psoriasis, impetigo herpetiformis, urticaria, erythema annulare centrifugum, pityriasis rosea, sarcoidosis, Sweet syndrome, and erythema nodosum, as well as glandular skin diseases, including acne vulgaris, acne rosacea, perioral dermatitis, hidradenitis suppurativa, Fox-Fordyce disease, hyperhidrosis, and miliaria. For each of these diseases, we discuss the pathogenesis, clinical presentation, and management with special consideration for maternal and fetal safety. PMID:27265071

    Uncontrolled inflammation of the periodontal area may arise when complex microbial communities transition from a commensal to a pathogenic entity. Communication among constituent species leads to polymicrobial synergy among metabolically compatible organisms that acquire functional specialization within the developing community. Keystone pathogens, even at low abundance, elevate community virulence and the resulting dysbiotic community targets specific aspects of host immunity to further disable immune surveillance while promoting an overall inflammatory response. Inflammophilic organisms benefit from proteinaceous substrates derived from inflammatory tissue breakdown. Inflammation and dysbiosis reinforce each other and the escalating environmental changes further select for a pathobiotic community. We have synthesized the polymicrobial synergy and dysbiotic components of the process into a new model for inflammatory diseases. PMID:25498392

    The teeth are unique in that they provide a direct pathway for spread of infection into surrounding osseous and soft tissue structures. Periodontal disease is the most common cause of tooth loss worldwide, referring to infection of the supporting structures of the tooth, principally the gingiva, periodontal ligament, cementum, and alveolar bone. Periapical disease refers to an infectious or inflammatory process centered at the root apex of the tooth, usually occurring when deep caries infect the pulp chamber and root canals. We review the pathogenesis, clinical features, and radiographic findings (emphasis on computed tomography) in periodontal and periapical disease. PMID:26589697

    AIMS: To assess the relation of plasma viscosity to disease activity in patients with inflammatory bowel disease. METHODS: Crohn's disease (n = 60) and ulcerative colitis (n = 71) were diagnosed on the basis of typical histological or radiological features. Active Crohn's disease was defined as a Crohn's disease activity index of 150 or over. Active ulcerative colitis was defined as a liquid stool passed three times a day or more with blood. Blood samples were assessed for haemoglobin concentration, total white cell count, platelets, plasma viscosity, erythrocyte sedimentation rate, serum albumin, and C-reactive protein. RESULTS: Plasma viscosity was higher in those with active Crohn's disease compared with those with inactive Crohn's disease or active ulcerative colitis. Plasma viscosity correlated significantly with erythrocyte sedimentation rate, C-reactive protein, and platelet count in patients with Crohn's disease. In ulcerative colitis plasma viscosity correlated only with serum C-reactive protein. Plasma viscosity showed a low sensitivity for detecting active Crohn's disease, with 48% of those with active disease having a plasma viscosity within the laboratory reference range. CONCLUSIONS: Plasma viscosity is related to disease activity in Crohn's disease, but is insufficiently sensitive for it to replace erythrocyte sedimentation rate as a measure of the acute phase response in Crohn's disease.

    Aim This paper synthesizes findings from available research about medication adherence to disease modifying anti-rheumatic drugs (DMARDs) in the rheumatoid arthritis (RA) population. Results This review of literature included 35 articles. Medication adherence to DMARDs ranged from 30% to 107%. Adherence rates greater than 100% indicated that patients took more than the prescribed amount of medication. There were no consistent risk factors for nonadherence to DMARD prescriptions identified, but some evidence was provided for self-efficacy, patient-health care provider relationships, social support, patient beliefs about medications, and age as factors affecting medication adherence. Support for educational interventions focused on medication adherence was equivocal. Conclusion Further research is necessary to develop a comprehensive, theoretically-based understanding of medication adherence in RA patients. PMID:20664466

    Our studies in children with rheumatic diseases have led to the identification of two of the oldest cytokines, type I Interferon (IFN) and Interleukin 1 (IL-1), as important pathogenic players in Systemic Lupus Erythematosus (SLE) and Systemic onset Juvenile Arthritis (SoJIA) respectively. These findings were obtained by studying the transcriptional profiles of patient blood cells and by assessing the biological and transcriptional effect(s) of active patient sera on healthy blood cells. We also identified a signature which can be used to promptly diagnose SoJIA from other febrile conditions. Finally, our pilot clinical trials using IL-1 blockers have shown remarkable clinical benefits in SoJIA patients refractory to other medications. PMID:18613829

    Video capsule endoscopy (VCE) has evolved to become an important tool for the non-invasive examination of the small bowel, which hitherto had been relatively inaccessible to direct visualisation. VCE has been shown to play a role in monitoring the activity of small bowel Crohn’s disease and can be used to assess the response to anti-inflammatory treatment in Crohn’s disease. For those patients with Crohn’s disease who have undergone an intestinal resection, VCE has been assessed as a tool to detect post-operative recurrence. VCE may also aid in the reclassification of patients with a diagnosis of Inflammatory Bowel Disease Unclassified to Crohn’s disease. The evolution of colon capsule endoscopy (CCE) has expanded the application of this technology further. The use of CCE to assess the activity of ulcerative colitis has been described. This advance in capsule technology has also fuelled interest in its potential role as a minimally invasive tool to assess the whole of GI tract opening the possibility of its use for the panenteric assessment of Crohn’s disease. VCE is a safe procedure. However, the risk of a retained capsule is higher in patients with suspected or confirmed Crohn’s disease compared with patients having VCE examination for other indications. A retained video capsule is rare after successful passage of a patency capsule which may be utilised to pre-screen patients undergoing VCE. This paper describes the use of VCE in the assessment of inflammatory bowel disease. PMID:27499830

  4. Chronic Inflammatory Diseases and Endothelial Dysfunction

    Chronic inflammatory diseases are associated with increases in cardiovascular diseases (CVD) and subclinical atherosclerosis as well as early-stage endothelial dysfunction screening using the FMD method (Flow Mediated Dilation). This phenomenon, referred to as accelerated pathological remodeling of arterial wall, could be attributed to traditional risk factors associated with atherosclerosis. Several new non-invasive techniques have been used to study arterial wall’s structural and functional alterations. These techniques (based of Radio Frequency, RF) allow for an assessment of artery age through calculations of intima-media thickness (RF- QIMT), pulse wave rate (RF- QAS) and endothelial dysfunction degree (FMD). The inflammatory and autoimmune diseases should now be considered as new cardiovascular risk factors, result of the major consequences of oxidative stress and RAS (Renin Angiotensin System) imbalance associated with the deleterious effect of known risk factors that lead to the alteration of the arterial wall. Inflammation plays a key role in all stages of the formation of vascular lesions maintained and exacerbated by the risk factors. The consequence of chronic inflammation is endothelial dysfunction that sets in and we can define it as an integrated marker of the damage to arterial walls by classic risk factors. The atherosclerosis, which develops among these patients, is the main cause for cardiovascular morbi-mortality and uncontrolled chronic biological inflammation, which quickly favors endothelial dysfunction. These inflammatory and autoimmune diseases should now be considered as new cardiovascular risk factors. PMID:26815098

    Epidemiological and experimental animal studies show that suboptimal environments in fetal and neonatal life exert a profound influence on physiological function and risk of diseases in adult life. The concepts of the 'developmental programming' and Developmental Origins of Health and Diseases (DOHaD) have become well accepted and have been applied across almost all fields of medicine. Adverse intrauterine environments may have programming effects on the crucial functions of the immune system during critical periods of fetal development, which can permanently alter the immune function of offspring. Immune dysfunction may in turn lead offspring to be susceptible to inflammatory and immune diseases in adulthood. These facts suggest that inflammatory and immune disorders might have developmental origins. In recent years, inflammatory and immune disorders have become a growing health problem worldwide. However, there is no systematic report in the literature on the developmental origins of inflammatory and immune diseases and the potential mechanisms involved. Here, we review the impacts of adverse intrauterine environments on the immune function in offspring. This review shows the results from human and different animal species and highlights the underlying mechanisms, including damaged development of cells in the thymus, helper T cell 1/helper T cell 2 balance disturbance, abnormal epigenetic modification, effects of maternal glucocorticoid overexposure on fetal lymphocytes and effects of the fetal hypothalamic-pituitary-adrenal axis on the immune system. Although the phenomena have already been clearly implicated in epidemiologic and experimental studies, new studies investigating the mechanisms of these effects may provide new avenues for exploiting these pathways for disease prevention.

    PubMed

    Brandtzaeg, P

    2001-08-01

    Inflammatory bowel disease (IBD) comprises two chronic, tissue-destructive, clinical entities Crohn disease (CD) and ulcerative colitis (UC) both apparently caused by immunological overreaction (hypersensitivity) to commensal gut bacteria. Under normal conditions the intestinal immune system shows a down-regulating tone ('oral tolerance') against dietary antigens and the indigenous microbiota. This local homeostasis is disturbed in IBD, leading to hyperactivation of T helper 1 (Th1) cells with abundant secretion of interferon-gamma and tumor necrosis factor (TNF) and production of IgG antibodies against commensal bacteria. In addition, UC includes genetically determined autoimmunity, particularly IgG1-mediated cytotoxic epithelial attack. Breaching of the epithelium is the best-defined event underlying abrogation of oral tolerance, but immune deviation caused by cytokines fiom irritated epithelial cells or subepithelial elements (for example, mast cells, natural killer cells, macrophages) may also be involved. Endogenous infection with local hypersensitivity likewise causes periodontal disease, reflecting 'frustrated' immune elimination mechanisms entertained by antigens from dental plaque. Altogether, perturbation of a tightly controlled cytokine network, with abnormal crosstalk between several cell types, apparently explains the progressive immunopathology of chronic inflammatory mucosal diseases in general. This adverse development will be influenced by numerous immunity genes, the dosage and potential pathogeniciy of commensal bacteria, general health, nutritional status, and psychological factors. Several targets for new therapy have tentatively been identified to block immunopathological mechanisms in IBD, and inhibition of TNF has a striking beneficial effect in CD, supporting a central role of this cytokine.

    Inflammatory bowel diseases (IBD), which consists of Crohn disease and ulcerative colitis, are chronic inflammatory conditions of the gastrointestinal tract. In genetically susceptible individuals, the interaction between environmental factors and normal intestinal commensal flora is believed to lead to an inappropriate immune response that results in chronic inflammation. The incidence of IBD have increased in the past century in developed and developing countries. The purpose of the present review is to summarize the current knowledge of the association between environmental risk factors and IBD. A number of environmental risk factors were investigated including smoking, hygiene, microorganisms, oral contraceptives, antibiotics, diet, breastfeeding, geographical factors, pollution and stress. Inconsistent findings among the studies highlight the complex pathogenesis of IBD. Additional studies are necessary to identify and elucidate the role of environmental factors in IBD etiology.

    Inflammatory bowel disease (IBD) comprises two distinct but related chronic relapsing inflammatory conditions affecting different parts of the gastrointestinal tract. Crohn’s disease is characterised by a patchy transmural inflammation affecting both small and large bowel segments with several distinct phenotypic presentations. Ulcerative colitis classically presents as mucosal inflammation of the rectosigmoid (distal colitis), variably extending in a contiguous manner more proximally through the colon but not beyond the caecum (pancolitis). This article highlights aspects of the presentation, diagnosis, and management of IBD that have relevance for paediatric practice with particular emphasis on surgical considerations. Since 25% of IBD cases present in childhood or teenage years, the unique considerations and challenges of paediatric management should be widely appreciated. Conversely, we argue that the organizational separation of the paediatric and adult healthcare worlds has often resulted in late adoption of new approaches particularly in paediatric surgical practice.

    Many identified and yet unknown factors contribute to the pathogenesis of inflammatory bowel disease (IBD). The genome-wide association studies clearly support the earlier developed concept that IBD occurs in genetically predisposed individuals who are exposed to distinct environmental factors, which together result in dysregulation of the mucosal immune system. Thus, the majority of previous studies have focused on the immune response within the intestinal wall. The present review aims to emphasize the contribution of three extraluminal structures to this inflammatory process, namely the mesenteric fat tissue, the lymphatics and the microvasculature. Broadening our view across the intestinal wall will not only facilitate our understanding of the disease, but will also us to identify future therapeutic targets. PMID:21350706

Only 22 cases of xanthogranulomatous cystitis (XGC) have been reported in the Japanese and English literature. In this report, we describe the twenty-third case of XGC and the third case associated with inflammatory bowel disease (IBD). A 50-year-old woman with quiescent Crohn’s disease was incidentally found to have a bladder mass on ultrasound. The lesion was resected through a transurethral approach. Pathology demonstrated XGC. At 3 months post-resection, there was no evidence of recurrence adjacent to the previous resection scar. PMID:20694091

    Introduction: Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by symmetrical polyarthritis and multisystemic involvement. Objective: The aim of this study was to assess the impact of low dose of methotrexate on bone mineral density (BMD) in patients with early rheumatoid arthritis (RA). Materials and methods: This paper follows a retrospective study, which involves 60 female patients with early onset RA diagnosed according to the American Rheumatism Association Criteria (ACR/EULAR 2010). The patients were divided into two groups group I was composed of thirty patients treated with dose of 7.5 mg/weekly methotrexate (MTX), while group II included thirty patients treated with dose of 2 g/daily sulfasalazine (SSZ). The Disease Activity was measured by a combination of Erythrocyte Sedimentation Rate (ESR) and Disease Activity Score (DAS-28). Bone mineral density of the lumbar spine (L2–4), and femoral neck, was measured by dual energy X-ray absorptiometry (DEXA) (Stratos 800). Laboratory findings included: In this study, we found no negative effect on BMD in RA patients treated with low dose MTX in comparison to patients treated with SSZ. There was not observed significant difference in BMD of the lumbar spine, femur neck or trochanter, of MTX and SSZ patients in the pretreatment phase, nor after 12 months of treatment. No significant change in the biochemical parameters of the both groups. Conclusion: Based on the results of our study, low dose of methotrexate has no negative effect on BMD in premenopausal RA patients. We believe that these results might provide new insights and that further longitudinal studies with larger groups of premenopausal RA patients are required. PMID:27147781

    A distinctive type of speckled antinuclear antibody staining pattern was identified by indirect immunofluorescence on mouse kidney substrate in 4.8% of 5,976 specimens analyzed for antinuclear antibodies. This pattern, termed variable large speckles (VLS), consisted of 3-10 nuclear speckles ranging in size from approximately 0.2-2.0 mu. The pattern could be differentiated from other indirect immunofluorescence patterns related to specific antibodies. The predominant immunoglobulin isotype demonstrating the VLS pattern was IgM in 27 of 28 sera examined and IgG in 1 serum. VLS sera had substantial IgM antibodies to histone demonstrated by enzyme immunoassay, and further analysis of representative sera showed predominant antibody activity to histone class 3 (H-3). Adsorption with histone H-3 resulted in decrease or removal of antibody producing the VLS pattern. Available information showed that most patients with IgM antibodies of the VLS pattern had undifferentiated connective tissue disease symptoms. They were characterized by a heterogeneity of chronic symptoms including arthralgias, myalgias, inflammatory polyarthritis, myositis, sicca symptoms, and pleurisy associated with elevation of the erythrocyte sedimentation rate. It remains to be determined whether the IgM anti-histone H-3 profile of these patients is a transient or long-standing serologic characteristic. PMID:2418845

There were numerous foci of collagen degeneration, characterized by fraying of the collagen fibers and accumulation of homogeneous granular material at these sites. Although the muscle changes were more striking, the connective tissue alterations appear important in the evolution of the chronic disease. The extent of collagen degeneration appeared to parallel the degree of collagen formation. The muscle fiber degeneration and connective tissue alterations did not correlate with the clinical findings. At the resolution of the electron microscope, the continuing process in the rheumatic heart appears to be primarily collagen formation and degradation rather than primary degeneration of the muscle fibers. It is the balance of these processes which determine the clinical state of the patient. Acute muscle damage along with evidence of inflammation do not seem to be associated with progressive, chronic rheumatic heart disease. ImagesFig 5Fig 6Fig 7Fig 1Fig 2Fig 3Fig 4 PMID:4767256

    MR colonography has a high diagnostic accuracy for detecting Crohn disease (CD) activity and determining the extent and severity of lesions. In the setting of stricturing CD, MR colonography can provide a detailed map of the lesions, which is useful for clinical decision making. MR colonography can be used as an alternative to conventional colonoscopy in the setting of CD, or as a complementary tool in selected patients with ulcerative colitis. This article reviews the spectrum of MR colonography findings in colonic inflammatory bowel disease and discusses the potential applications and limitations of MR colonography. PMID:24238130

    Managing the health of individual patients suffering from complex disorders is a challenge and is costly. Inflammatory bowel disease (IBD) is a prototypic complex disorder of the small and large intestines. Susceptibility is complex, severity is variable, and response to treatment is unpredictable. Di Narzo et al. (Clin Transl Gastroenterol 7: e177; doi:10.1038/ctg.2016.34) bring diverse teams of physicians and scientists together to break down the mechanisms of IBD by linking pathogenic genetic variants with altered gene expression in specific cell types causing IBD. Framing new findings in the context of other complex diseases provides a roadmap for predictive medicine. PMID:27607898

    Inflammation is considered as one of the major causes for the initiation of various chronic diseases such as asthma, cancer, cardiovascular disease, diabetes, obesity, inflammatory bowel disease, osteoporosis and neurological diseases like Parkinson's disease. Increasing scientific evidence has delineated that inflammatory markers such as TNF-α, IL-1, IL-6, IL-8 and CRP and different transcription factors such as NF-κB and STAT are the major key factors that regulate these inflammatory diseases. Food protein-derived bioactive peptides have been shown to exhibit anti-inflammatory activity by inhibiting or reducing the expression of these inflammatory biomarkers and/or by modulating the activity of these transcription factors. This review aims to discuss various molecular targets and underlying mechanisms of food protein-derived anti-inflammatory peptides and to explore their potential against various chronic inflammatory diseases. © 2015 Society of Chemical Industry.

    It is necessary and useful to explore prevalence of various systemic autoimmune rheumatic diseases (SARDs) in patients with suspicion of having SARDs and to characterize antinuclear antibodies (ANA) profile for identifying different populations (SARDs and non-SARDs). A total of 5024 consecutive patients with available medical records were investigated, whose sera had been tested for ANA profile, including ANA, anti-dsDNA and anti-extractable nuclear antigen (ENA) antibodies, between 31 January 2012 and 26 March 2014. Only 594 (11.8%) patients were diagnosed with SARDs of those suspected with SARDs. The prevalence of systemic lupus erythematosus (SLE) was highest (3.2%), followed by rheumatoid arthritis (RA) (2.5%), primary Sjögren's syndrome (pSS) (1.7%), ankylosing spondylitis (AS) (1.5%), etc. Of females, SLE also showed the highest prevalence (6%), while of males, AS showed the highest prevalence (1.9%). The prevalence of most SARDs was closely associated with age, except mixed connective tissue disease (MCTD), and the variation characteristics among different age groups were different among various SARDs. The prevalence of ANA was significantly increased in most SARD patients [especially in SLE, systemic sclerosis (SSc) and MCTD]. For anti-ENA antibodies, in contrast to some autoantibodies associated with multiple SARDs (e.g. anti-SSA, SSB, nRNP), others were relatively specific for certain diseases, such as anti-dsDNA, Sm, histone, nucleosome and Rib-P for SLE, anti-SCL-70 for SSc and anti-Jo-1 for polymyositis/dermatomyositis (PM/DM). Of note, ANA profile appeared to be of little significance for AS, ANCA-associated vasculitis (AAV), polymyalgia rheumatic (PMR), adult-onset Still's disease (ASD) and Behcet's disease (BD). The younger were more likely to have the presence of anti-dsDNA, Sm, histone or Rib-P for SLE, and anti-SSA for RA or MCTD. No significant differences for frequencies of ANA and anti-ENA autoantibodies were found between sexes in most SARDs

    Bronchopulmonary signs and symptoms are examples of variable extraintestinal manifestations of the inflammatory bowel diseases (IBD). These complications of Crohn's disease (CD) and ulcerative colitis (UC) seem to be underrecognized by both pulmonary physicians and gastroenterologists. The objective of the present review was to gather and summarize information on this particular matter, on the basis of available up-to-date literature. Tracheobronchial involvement is the most prevalent respiratory presentation, whereas IBD-related interstitial lung disease is less frequent. Latent and asymptomatic pulmonary involvement is not unusual. Differential diagnosis should always consider infections (mainly tuberculosis) and drug-induced lung pathology. The common link between intestinal disease and lung pathology is unknown, but many hypotheses have been proposed. It is speculated that environmental pollution, common immunological mechanisms and predisposing genetic factors may play a role. PMID:26788078

    Inflammatory bowel diseases [IBD; Crohn's disease (CD), ulcerative colitis (UC)] are chronic immunologically mediated diseases that are due to a dysregulated immune response to intestinal flora in a genetically susceptible host. Despite advances in genetics, the likelihood of occurrence of disease remains incompletely explained and there appears to be a strong role for the environment in mediating risk of disease. Smoking remains the most widely studied and replicated risk factor, contributing to increased risk and severity of CD while conferring protection against UC. Recent data has suggested novel risk factors. Lower plasma vitamin D is associated with an increased risk of Crohn's disease, and vitamin D supplementation may prevent relapse of disease. Several medications including oral contraceptives, post-menopausal hormone replacement, aspirin, NSAIDs, and antibiotics may increase risk of CD or UC with the mechanisms of effect remaining inadequately defined. There is continuing evidence that depression and psychosocial stress may play a role in the pathogenesis of both CD and UC, while at the same time also increasing risk for disease flares. There is also a growing understanding of the role of diet on IBD, in particular through its effect on the microbiome. Animal protein intake and n-6 fatty acids may increase risk of UC while n-3 fatty acids and dietary fiber may confer protection. The effect of diet on established disease remains poorly studied. There is need for routine measurement of a spectrum of environmental exposures in prospective studies to further our understanding. PMID:23250702

Although IBD primarily affects the intestinal tract, extraintestinal manifestations of the disease are often apparent, including in the oral cavity, especially in CD. Specific oral manifestations in patients with CD are as follows: indurate mucosal tags, cobblestoning and mucogingivitis, deep linear ulcerations and lip swelling with vertical fissures. The most common non-specific manifestations, such as aphthous stomatitis and angular cheilitis, occur in both diseases, while pyostomatitis vegetans is more pronounced in patients with UC. Non-specific lesions in the oral cavity can also be the result of malnutrition and drugs. Malnutrition, followed by anemia and mineral and vitamin deficiency, affects the oral cavity and teeth. Furthermore, all of the drug classes that are applied to the treatment of inflammatory bowel diseases can lead to alterations in the oral cavity due to the direct toxic effects of the drugs on oral tissues, as well as indirect immunosuppressive effects with a risk of developing opportunistic infections or bone marrow suppression. There is a higher occurrence of malignant diseases in patients with IBD, which is related to the disease itself and to the IBD-related therapy with a possible oral pathology. Treatment of oral lesions includes treatment of the alterations in the oral cavity according to the etiology together with treatment of the primary intestinal disease, which requires adequate knowledge and a strong cooperation between gastroenterologists and specialists in oral medicine.

    The introduction of biological therapies, particularly anti-TNFα agents, has revolutionized the management of inflammatory bowel disease in those cases which are refractory to conventional treatment; however these drugs are not risk-free and their use has substantially increased the cost of treatment. As marketing protection expires for original, first-generation biopharmaceuticals, lower-cost "copies" of these drugs produced by competitor companies-referred to as biosimilars-are already entering the market. In September 2013, the European Medicines Agency approved two infliximab biosimilars for treatment of adult and paediatric inflammatory bowel disease patients, a decision based largely on efficacy and safety data generated in studies of patients with ankylosing spondylitis and rheumatoid arthritis. For many clinicians, extrapolation practices and the general question of interchangeability between biosimilars and reference biologics are cause for concern. In the present paper, the Italian Group for inflammatory bowel disease presents its statements on these issues, with emphasis on the peculiar clinical characteristics of inflammatory bowel disease and the importance of providing physicians and patients with adequate information and guarantees on the safety and efficacy of these new drugs in the specific setting of inflammatory bowel disease.

    Bacteria play an important role in the pathogenesis of inflammatory bowel disease (IBD), its complications and its symptoms. Antibiotics can decrease tissue invasion and eliminate aggressive bacterial species. They are used in IBD to treat infective complications and for altering bacterial flora, which may result in specific anti-inflammatory effects. In addition, suppression of bacterial metabolic activities or direct effects of antibiotics on intestinal structures and functions may result in symptoms which cannot be differentiated from symptoms caused by inflammation. Although current clinical trials do not fulfill criteria of evidence-based treatment, a few placebo- or standard treatment-controlled studies suggest that metronidazole and ciprofloxacin are effective in Crohn's colitis and ileocolitis, perianal fistulae and pouchitis. Administration of probiotics, prebiotics and synbiotics can restore a predominance of beneficial species. However, beneficial effects of probiotics in IBD are modest, strain-specific and limited to certain manifestations of disease and duration of use of the probiotic. For probiotics there is reasonable evidence of efficacy in relapse prevention in chronic pouchitis and ulcerative colitis, and suggestive evidence for postoperative prevention in pouchitis. Therapeutic manipulation of the intestinal flora offers considerable promise for treating IBD, but must be supported by large controlled therapeutic trials before widespread clinical acceptance. These agents may become a component of treating IBD in combination with traditional anti-inflammatory and immunosuppressive agents. Probiotic strategies, based on metagenomic or metabonomic analyses, and new classes of probiotics might play an important role in the future management of IBD. PMID:22179210

    Gastrointestinal (GI) disorders, especially microbial dysbiosis play role in several GI ailments such as irritable bowel syndrome, colorectal cancer, inflammatory bowel diseases, and antibiotic-associated diarrhoea. Role of inflammatory bowel disease (IBD) is multifactorial as it involves loss of maintaining intestinal epithelial barrier integrity, increased release of pro-inflammatory molecules, and microbial dysbiosis in gut microflora. Some specific pathogens also play a key role in the IBD development. The origin and causation are still in unfathomable condition and the exact root cause is unknown. Recently probiotic studies have been gaining importance because of their positive responses in their IBD experimental results. According to joint Food and Agricultural Organisation/World Health Organisation working group, probiotics are defined as live microorganisms which when administered in adequate amount confer health benefit on the host. These live beneficial microorganisms are considered helpful in improving gut colonization and perseverance thereby improves prophylactic effect. In the direction of IBD research, a number of studies are needed to standardize its methodology and its applicability on human usage. The particular review presents an overview of gut microflora and its impact on host health, types of IBD and existing therapies to treat this disorder, mechanism of several probiotic actions, role of probiotics in IBD prevention with their supporting evidences.

    The ability of leucocytes to adhere to endothelium is essential for leucocyte migration into inflammatory sites. Some of these adhesion molecules are released from the cell surface and can be detected in serum. The soluble adhesion molecules intercellular adhesion molecule 1 (ICAM-1), E selectin, and vascular cell adhesion molecule 1 (VCAM-1) were studied in the serum of patients with Crohn's disease, ulcerative colitis, and healthy controls. A second blood sample was taken from patients with active disease after one month of treatment and a third two months after remission was achieved. Tissue expression of the same adhesion molecules was studied by immunohistology. Circulating VCAM-1 concentrations were significantly higher in patients with active ulcerative colitis (n = 11, median = 165 U/ml) compared with patients with inactive ulcerative colitis (n = 10, median = 117 U/ml, p < 0.005), active Crohn's disease (n = 12, median = 124 U/ml, p < 0.02), and controls (n = 90, median = 50 U/ml, p < 0.0001). Within each disease group there were no significant differences in E selectin or ICAM-1 concentrations between the active and inactive states, however, patients with active Crohn's disease had significantly higher ICAM-1 concentrations (n = 12, median = 273 ng/ml) than controls (n = 28, median = 168, p < 0.003). VCAM-1 concentrations fell significantly from pretreatment values to remission in active ulcerative colitis (p < 0.01). In Crohn's disease there was a significant fall in ICAM-1 both during treatment (p < 0.01) and two months after remission (p < 0.02). Vascular expression of ICAM-1 occurred more often and was more intense in inflamed tissue sections from patients with ulcerative colitis and Crohn's disease than from controls. Vascular labelling with antibody to E selectin also occurred more often in patients with active inflammatory bowel disease. In conclusion, increased circulating concentrations of selected adhesion molecules are associated with

    Pyoderma gangrenosum (PG) and Sweet's Syndrome (SS) are inflammatory skin diseases caused by the accumulation of neutrophils in the skin and, rarely, in internal organs, which led to coining the term of neutrophilic dermatoses (ND) to define these conditions. Recently, ND have been included among the autoinflammatory diseases, which are forms due to mutations of genes regulating the innate immune responses. Both PG and SS are frequently associated with inflammatory bowel diseases (IBD), a group of chronic intestinal disorders which comprises ulcerative colitis and Crohn's disease and whose pathogenesis involves both the innate and adaptive immunity in genetically prone individuals. Patients with IBD develop PG in 1-3% of cases, while SS is rarer. PG presents with deep erythematous-to-violaceous painful ulcers with undermined borders, but bullous, pustular, and vegetative variants can also occur. SS, also known as acute febrile neutrophilic dermatosis, is characterized by the abrupt onset of fever, peripheral neutrophilia, tender erythematous skin lesions and a diffuse neutrophilic dermal infiltrate. In this review that will be focused on PG and SS, we will describe also the aseptic abscesses syndrome, a new entity within the spectrum of ND which frequently occurs in association with IBD and is characterized by deep abscesses mainly involving the spleen and skin and by polymorphic cutaneous manifestations including PG- and SS-like lesions.

    Inflammatory bowel disease (IBD) is a disease that affects the intestinal tract via an inflammatory process. Patients who suffer from IBD often have diseases that affect multiple other organ systems as well. These are called extraintestinal manifestations and can be just as, if not more debilitating than the intestinal inflammation itself. The skin is one of the most commonly affected organ systems in patients who suffer from IBD. The scientific literature suggests that a disturbance of the equilibrium between host defense and tolerance, and the subsequent over-activity of certain immune pathways are responsible for the cutaneous disorders seen so frequently in IBD patients. The purpose of this review article is to give an overview of the types of skin diseases that are typically seen with IBD and their respective pathogenesis, proposed mechanisms, and treatments. These cutaneous disorders can manifest as metastatic lesions, reactive processes to the intestinal inflammation, complications of IBD itself, or side effects from IBD treatments; these can be associated with IBD via genetic linkage, common autoimmune processes, or other mechanisms that will be discussed in this article. Ultimately, it is important for healthcare providers to understand that skin manifestations should always be checked and evaluated for in patients with IBD. Furthermore, skin disorders can predate gastrointestinal symptoms and thus may serve as important clinical indicators leading physicians to earlier diagnosis of IBD. PMID:22347192

Recently, compounds targeting the intracellular kinase, Janus kinase (JAK) have demonstrated therapeutic effects resembling biologics. Tofacitinib is the only JAK inhibitor approved for RA and during the clinical trial, increased events of herpes zoster (HZ) was observed. Incidence rate was twice as much as patients treated with conventional anti-rheumatic drug and was especially increased in Japan that was four times as much. The risk factors were age and glucocorticoid that is identical to that of common RA patients and there was nothing specific for tofacitinib. Mechanism of increased incidence of HZ and the difference in ethnicity remains unknown. Analysis of clinical trials have identified that HZ do not correlate with further adverse events. Therefore, it is extremely important to accumulate clinical data with considerable amount of patients with long term follow up including the post marketing surveillance in Japan to reveal the significance of increased HZ in RA patients.

    Despite all of the advances in our understanding of the pathophysiology of inflammatory bowel disease (IBD), we still do not know its cause. Some of the most recently available data are discussed in this review; however, this field is changing rapidly and it is increasingly becoming accepted that immunogenetics play an important role in the predisposition, modulation and perpetuation of IBD. The role of intestinal milieu, and enteric flora in particular, appears to be of greater significance than previously thought. This complex interplay of genetic, microbial and environmental factors culminates in a sustained activation of the mucosal immune and non-immune response, probably facilitated by defects in the intestinal epithelial barrier and mucosal immune system, resulting in active inflammation and tissue destruction. Under normal situations, the intestinal mucosa is in a state of 'controlled' inflammation regulated by a delicate balance of proinflammatory (tumour necrosis factor [TNF]-alpha, interferon [IFN]-gamma, interleukin [IL]-1, IL-6, IL-12) and anti-inflammatory cytokines (IL-4, IL-10, IL-11). The mucosal immune system is the central effector of intestinal inflammation and injury, with cytokines playing a central role in modulating inflammation. Cytokines may, therefore, be a logical target for IBD therapy using specific cytokine inhibitors. Biotechnology agents targeted against TNF, leukocyte adhesion, T-helper cell (T(h))-1 polarisation, T-cell activation or nuclear factor (NF)-kappaB, and other miscellaneous therapies are being evaluated as potential therapies for IBD. In this context, infliximab is currently the only biologic agent approved for the treatment of inflammatory and fistulising Crohn's disease. Other anti-TNF biologic agents have emerged, including CDP 571, certolizumab pegol (CDP 870), etanercept, onercept and adalimumab. However, ongoing research continues to generate new biologic agents targeted at specific pathogenic mechanisms involved

    A complex mucosal barrier protects as the first line of defense the surface of the healthy intestinal tract from adhesion and invasion by luminal microorganisms. In this review, we provide an overview about the major components of this protective system as for example an intact epithelium, the synthesis of various antimicrobial peptides (AMPs) and the formation of the mucus layer. We highlight the crucial importance of their correct functioning for the maintenance of a proper intestinal function and the prevention of dysbiosis and disease. Barrier disturbances including a defective production of AMPs, alterations in thickness or composition of the intestinal mucus layer, alterations of pattern-recognition receptors, defects in the process of autophagy as well as unresolved endoplasmic reticulum stress result in an inadequate host protection and are thought to play a crucial role in the pathogenesis of the inflammatory bowel diseases Crohn’s disease and ulcerative colitis.

    The development of new semilong enteroscopes, videopush enteroscope (VPE), has modified the diagnostic and therapeutic approach to inflammatory intestinal diseases owing to the biopsy and therapeutic capacities. In Crohn's Disease, VPE is useful in nonusual clinical presentations: occult intestinal bleeding and in the treatment by dilatation of jejunal and ileal strictures. In atrophic coeliac disease (ACD) VPE is mandatory each time oesogastroduodenoscopy biopsies are noninformative in order to obtain pathologic jejunal biopsis. In addition, in refractory ACD and in the case of jejunal blood loss ACD, VPE is mandatory in the search for ulcerative jejunitis and lymphoma. The management of chronic diarrhea of the adult, classic endoscopy remains the gold standard procedure and is carried out first but in patients with negative results, VPE can proceed immediately. Good results can only be obtained if VPE is performed by endoscopist who is highly interested in this field of investigation. PMID:9834320

    Inflammatory bowel disease is often accompanied by extraintestinal manifestations due to a common autoimmune etiopathogenesis, chronic systemic inflammation, frequent nutrition deficits, and the treatment. Endocrine system changes belong to manifestations too. Interaction is mutual, Crohn's disease and ulcerative colitis cause functional and morphological changes of endocrine tissues. On the other hand the endocrine disorders negatively influence the course of bowel disease. In the article we analyze correlation of IBD with gonadal hormone production and fertility, with adrenal function, with the function and morphology of the thyroid, with growth hormone production and growth disorders in children, and with bone mineral density reduction. This topic is not studied enough and needs more analysis and clarification. PMID:27124970

    The diagnosis of inflammatory bowel disease (IBD) depends on direct endoscopic visualization of the colonic and ileal mucosa and the histological study of the obtained samples. Radiological and scintigraphic methods are mainly used as an adjunct to endoscopy. In this review, we focus on the diagnostic potential of nuclear medicine procedures. The value of all radiotracers is described with special reference to those with greater experience and more satisfactory results. Tc-99m hexamethylpropylene amine oxime white blood cells remain a widely acceptable scintigraphic method for the diagnosis of IBD, as well as for the evaluation of disease extension and severity. Recently, pentavalent Tc-99m dimercaptosuccinic acid has been recommended as an accurate variant and a complementary technique to endoscopy for the follow-up and assessment of disease activity. Positron emission tomography alone or with computed tomography using fluorine-18 fluorodeoxyglucose appears to be a promising method of measuring inflammation in IBD patients. PMID:19522018

    Inflammatory bowel disease (IBD) usually affects women during their reproductive years and many concerns arise among these young patients. Pre-pregnancy consultation with a multi-disciplinary team is very important. The team should make patients aware of the critical importance of ensuring that conception occurs during a period of disease remission. Conception during an IBD flare-up results in disease activity or even exacerbates disease in two-thirds of women. Exacerbation of the disease is associated with increased frequency of maternal and fetal complications. Drug therapy constitutes a considerable source of patient anxiety but most drugs used for treating IBD are considered safe. Therefore, continuing pharmacological therapy during pregnancy is necessary to maintain disease control. Optimization of pre-conception nutritional status and smoking cessation are also emphasized. The general guideline for most patients, except for active perianal disease patients, is to aim for vaginal delivery in the absence of obstetric contraindications. Consistent, ongoing follow-up, as detailed in this review, should allay the anxieties and fears surrounding continuing immunosuppressive drugs during pregnancy, allowing each patient to attain the optimal conditions for achieving her goal of holding a healthy baby.

    Extracellular purines have a role in renal physiology and adaption to inflammation. However, inflammatory renal disease may be mediated by extracellular purines, resulting in renal injury. The role of purinergic signaling is dependent on the concentrations of extracellular purines. Low basal levels of purines are important in normal homeostasis and growth. Concentrations of extracellular purines are significantly elevated during inflammation and mediate either an adaptive role or propagate local inflammation. Adenosine signaling mediates alterations in regional renal blood flow by regulation of the renal microcirculation, tubulo-glomerular feedback, and tubular transport of sodium and water. Increased extracellular ATP and renal P2 receptor-mediated inflammation are associated with various renal diseases, including hypertension, diabetic nephropathy, and glomerulonephritis. Experimental data suggests P2 receptor deficiency or receptor antagonism is associated with amelioration of antibody-mediated nephritis, suggesting a pathogenic (rather than adaptive) role of purinergic signaling. We discuss the role of extracellular nucleotides in adaptation to ischemic renal injury and in the pathogenesis of inflammatory renal disease. PMID:23908631

    The gut bacterial microbiome, particularly its role in disease and inflammation, has gained international attention with the successful use of fecal microbiota transplantation (FMT) in the treatment of Clostridium difficile infection. This success has led to studies exploring the role of FMT in other conditions, including inflammatory bowel disease (IBD). Both Crohn’s disease and ulcerative colitis are chronic inflammatory conditions of the gastrointestinal system that have multifactorial etiologies. A shift in gut microbial composition in genetically susceptible individuals, an altered immune system, and environmental factors are all hypothesized to have a role in the pathogenesis of IBD. While numerous case reports and cohort studies have described the use of FMT in patients with IBD over the last 2 decades, the development of new sequencing techniques and results from 2 recent randomized, controlled trials have allowed for a better understanding of the relationship between the microbiome and the human host. However, despite these efforts, knowledge remains limited and the role of FMT in the management of IBD remains uncertain. Further investigation is necessary before FMT joins the current armamentarium of treatment options in clinical practice. PMID:27493597

    To assess the effect of the addition of enteral tube feeding with polymeric diets to the standard treatment of acute attacks of inflammatory bowel disease a total of 43 patients admitted to hospital (23 with Crohn's disease and 20 with ulcerative colitis) were studied retrospectively. Total enteral nutrition was given to 26 as the sole nutritional supply and to 17 in conjunction with a normal ward diet, when appropriate, according to the severity of attack (control group). Nutritional state was assessed and classified in all patients at admission and at the end of the study, by measuring the triceps skinfold thickness, mid arm muscle circumference, and serum albumin concentration as representative of body fat, muscle protein, and visceral protein, respectively. At admission the three nutritional variables were not statistically different between the groups. There was a significantly positive effect on mid arm muscle circumference in patients on total enteral nutrition compared with the control group, but there was no effect on either triceps skinfold thickness or serum albumin concentration. The percentage of subjects requiring intravenous albumin infusion, however, was significantly less in the group fed enterally than in the control group. In addition, fewer patients in the group fed enterally required surgical treatment compared with the control group, despite the fact that one of the criteria for starting enteral nutritional support was the expectancy that surgery would be needed. Total enteral nutrition was well tolerated and no major side effects arose during its use in patients with acute exacerbations of inflammatory bowel disease. PMID:3098646

    There is a risk of misdiagnosis between benfluorex-induced VHD and acute rheumatic fever (ARF)-related VHD due to common characteristics of both etiologies. We aimed at estimating the probability for a patient exposed to benfluorex presenting with VHD to have, at the same time, a history of ARF-related VHD. Such epidemiological approach could help at reducing the risk of misdiagnosis. We used INSEE data and related literature as well as various modeling hypotheses to drive and test a formula for calculating the probability of a patient presenting with VHD and a history of benfluorex intake to have a prior history of ARF-related VHD. Different scenarios were estimated by a Markov model on the life course of people born in France between 1940 and 1960. Sensitivity analyses were performed under these scenarios. According to the different scenarios and gender, the probability that a patient born between 1940 and 1960 presenting with VHD and a history of benfluorex intake would have had a prior history of ARF-related VHD varied from 0.2% to 2.7%. The probabilities by the year of birth were as follows: 0.8%–2.7% for a patient born in 1940, < 0.5% in all scenarios for patients born after 1955, and < 0.2% in all scenarios for patients, born in 1960. Our results indicate that the burden of ARF-related VHD is low in the patient population exposed to benfluorex. The probability of ARF related VHD should not be over-estimated in the diagnostic procedure of VHD. PMID:27487042

  8. Rheumatic heart disease screening by "point-of-care" echocardiography: an acceptable alternative in resource limited settings?

    Rheumatic heart disease (RHD) is estimated to affect over 20 million people worldwide, the vast majority being in developing countries. Screening for RHD has been recommended by World Health Organization (WHO) since 2004. Conventionally, auscultation has been used for diagnosing RHD. Auscultation has its limitations and may not detect mild cases. With the evolution of portable echocardiographic systems, mass screening for subclinical RHD has become possible. Portable echo has the advantage of rapid access and hence screening in schools or communities is possible. Its cost is lower than that of standard echo equipment. A large number of studies have reported echocardiographic screening for RHD over the last decade or so. A 3-10 fold increase in prevalence of RHD has been detected by using portable echo when compared with conventional method of auscultation. More recently, a small, compact, easy to carry in a pocket, hand held system has been introduced which is much cheaper than the conventional portable system. A few previous reports have shown the feasibility of using hand held echo system for diagnosis of various cardiac diseases. A recently published article has shown that the hand held system can be used to screen for RHD. It is more sensitive than the conventional auscultation for RHD. Authors of this report have concluded that screening with the hand held device may be a more cost effective strategy for screening for RHD in resource limited settings, since it is much cheaper than the portable echocardiography equipment.

    When new evidence comes to light, it compels us to contemplate the implications of such evidence for health policy and practice. This article examines recent research evidence on the prevalence of asymptomatic rheumatic heart disease (RHD) in South Africa and considers the implications for the Integrated School Health Programme (ISHP). RHD is still a major burden of disease in developing countries, and elimination of this preventable condition ranks high among World Heart Federation goals. If left untreated, it becomes a chronic health condition that individuals have to cope with into their adult lives. The ISHP regards the health needs of children with chronic health conditions, which include conditions such as RHD, as a key service component. However, the chronic health component of the ISHP is still poorly developed and can benefit from good evidence to guide implementation. A recent study to ascertain the prevalence of RHD in asymptomatic schoolchildren through mass screening affords an opportunity to reflect on whether, and how, asymptomatic chronic health conditions in schoolchildren could be addressed, and what the implications would be if this were done through a school-based programme such as the ISHP.

    Inflammatory bowel disease (IBD) is characterized by chronic inflammation of the gastrointestinal tract and is associated with significant morbidity. The etiology of IBD has been extensively studied during the last several decades; however, causative factors in disease pathology are not yet fully understood. IBD is thought to result from the interaction between genetic and environmental factors that influence the normal intestinal commensal flora to trigger an inappropriate mucosal immune response. Although many IBD susceptibility genes have been discovered, similar advances in defining environmental risk factors have lagged. A number of environmental risk factors have been explored, including smoking, appendectomy, oral contraceptives, diet, breastfeeding, infections/ vaccinations, antibiotics, and childhood hygiene. However, most of these factors have demonstrated inconsistent findings, thus making additional studies necessary to better understand the etiology of IBD. PMID:20567592

    Inflammatory bowel disease (IBD) affects body image, relationships, family planning, fertility and pregnancy outcomes. However, the common misconception that IBD is a contraindication, or serious concern, in pregnancy is essentially a myth. Most patients with IBD can expect to have uneventful pregnancies. We present an overview of the management of IBD during pregnancy, including management in those planning pregnancy, the suitability of relevant medication during pregnancy and breast feeding, investigation and monitoring of IBD during pregnancy, surgical management and considerations relating to delivery. While there are some definite alterations required in the management of IBD during pregnancy, management is essentially unchanged. With close attention to aspects such as nutrition and smoking cessation, and optimal disease control in the run-up to and during pregnancy, we have an opportunity to help our patients with IBD achieve good pregnancy outcomes.

With >160 susceptible loci identified for IBD, the goals now are to understand at a fundamental level, the function of these susceptibility alleles. Clinical relevance of how these susceptible genes shape the development of IBD is also a high priority. The main challenge is to understand how the environment and microbiome play a role in triggering disease in genetically susceptible individual, as the interactions may be complex. To advance the field, novel in vitro and mouse models that are designed to interrogate complex genetics and be able to functionally test hypotheses are needed. Ultimately, the goal of genetics studies will be to translate genetics to the patients with IBD and improve their care. PMID:26907531

    The use of thiopurines as immunosuppression for the treatment of refractory or chronic active inflammatory bowel disease is established for both Crohn's disease and ulcerative colitis. Nevertheless, many questions remain concerning the optimal treatment regimens of azathioprine, 6-mercaptopurine and thioguanine. We will briefly summarize dose recommendations, indications for thiopurine therapy and side effects which are relevant in clinical practice. We discuss some currently debated topics, including the combination of azathioprine and allopurinol, switching of thiopurine therapy in case of side effects, the use of azathioprine in pregnancy, the infection risk using thiopurines and the evidence when to stop thiopurines. Excellent reviews have been published on the thiopurine metabolic pathway which will not be discussed here in detail. PMID:23467510

    Inflammatory bowel disease (IBD), Crohn's disease and ulcerative colitis comprise conditions characterized by chronic, relapsing immune activation and inflammation within the gastrointestinal tract. Objective estimation of intestinal inflammation is the mainstay in the diagnosis and observation of IBD, but is primarily dependent on expensive and invasive procedures such as endoscopy. Therefore, a simple, noninvasive, inexpensive, and accurate test would be extremely important in clinical practice. Fecal calprotectin is a calcium-containing protein released into the lumen that is excreted in feces during acute and chronic inflammation. It is well-researched, noninvasive, and has high sensitivity and specificity for identification of inflammation in IBD. This review will focus on the use of fecal calprotectin to help diagnose, monitor, and determine treatment in IBD. PMID:27206433

    Inflammatory bowel disease (IBD) is presently one of the most investigated human disorders. Expansion of knowledge of its pathophysiology has helped in developing novel medications to combat gut inflammation with a considerably degree of success. Despite this progress, much more remains to be done in regard to gaining a more profound understanding of IBD pathogenesis, detecting inflammation before it clinically manifests, implementing lifestyle modifications, and developing agents that can modify the natural course of the disease. One of the limitations to achieve these goals is the lack of integration of the major components of IBD pathogenesis, that is the exposome, the genome, the gut microbiome, and the immunome. An "IBD integrome" approach that takes advantage of all functional information derived from the detailed investigation of each single pathogenic component through the use of systems biology may offer the solution to understand IBD and cure it.

    For a long time the relationship between inflammatory bowel diseases (IBDs) and psoriasis has been investigated by epidemiological studies. It is only starting from the 1990s that genetic and immunological aspects have been focused on. Psoriasis and IBD are strictly related inflammatory diseases. Skin and bowel represent, at the same time, barrier and connection between the inner and the outer sides of the body. The most important genetic correlations involve the chromosomal loci 6p22, 16q, 1p31, and 5q33 which map several genes involved in innate and adaptive immunity. The genetic background represents the substrate to the common immune processes involved in psoriasis and IBD. In the past, psoriasis and IBD were considered Th1-related disorders. Nowadays the role of new T cells populations has been highlighted. A key role is played by Th17 and T-regs cells as by the balance between these two cells types. New cytokines and T cells populations, as IL-17A, IL-22, and Th22 cells, could play an important pathogenetic role in psoriasis and IBD. The therapeutic overlaps further support the hypothesis of a common pathogenesis. PMID:23971052

    2009-01-01

    The pathogenesis of inflammatory bowel disease (IBD) involves an interaction between host susceptibility (which is partly genetically determined), mucosal immunity and the intestinal milieu. Micro-organisms have physiological effects on mucosal structure, epithelial turnover, the intestinal immune cells and, thus, on many intestinal functions. Toll-like receptors and nucleotide oligomerisation-binding domain proteins in host cells recognise specific bacterial molecules and modify the immune response. Human studies have repeatedly shown that the microbiota of patients with IBD differs from that of controls and is unstable, both in the intestinal lumen and at the surface of the mucosa. A single pathogen has not been identified, but potentially pro-inflammatory micro-organisms have been found in samples from IBD patients more often than from healthy controls. These include Mycobacterium paratuberculosis, and enteroadherent and invasive Escherichia coli in Crohn's disease (CD). Ecological descriptions of the microbiota present in patients with IBD (either in the faeces or adherent to the mucosa) have repeatedly reported a decrease in usually dominant bacteria, especially those from the dominant phylum Firmicutes. A decrease in the biodiversity of Firmicutes has been observed in CD, while a recent study has shown that a decrease in Firmicutes, especially Faecalibacterium prausnitzii, was associated with CD and the post-operative recurrence of CD lesions in the ileum. Taken together, these results suggest that dysbiosis, or an imbalance within the (dominant) intestinal microbiota, may favour IBD. PMID:20203504

    Anti-TNF medications have revolutionized the care of patients with inflammatory bowel disease. However, despite an initial robust effect, loss of response is common and long-term results are disappointing. Much of this lack of durability may be due to inadequate dose optimization, and recent studies suggest a correlation between serum drug concentrations and clinical outcomes. Currently, in clinical practice, measurement of drug concentrations and antibodies to drug are typically performed only when a patient presents with active inflammatory bowel disease symptoms or during a potential immune-mediated reaction to anti-TNF ("reactive" setting). However, proactive monitoring of anti-TNF concentrations with titration to a therapeutic window (i.e., therapeutic concentration monitoring) represents a new strategy with many potential clinical benefits including prevention of immunogenicity, less need for IFX rescue therapy, and greater durability of IFX treatment. This review will cover the salient features of anti-TNF pharmacokinetics and pharmacodynamics and provide a rational approach for the use of anti-TNF concentration testing in both the reactive and proactive settings.

    2014-01-01

    The epithelium of the gastrointestinal tract is one of the most versatile tissues in the organism, responsible for providing a tight barrier between dietary and bacterial antigens and the mucosal and systemic immune system, while maintaining efficient digestive and absorptive processes to ensure adequate nutrient and energy supply. Inflammatory Bowel Diseases (IBD; Crohn’s disease and ulcerative colitis) are associated with a breakdown of both functions, which in some cases are clearly interrelated. In this updated literature review, we focus on the effects of intestinal inflammation and the associated immune mediators on selected aspects of the transepithelial transport of macro- and micronutrients. The mechanisms responsible for nutritional deficiencies are not always clear and could be related to decreased intake, malabsorption and excess losses. We summarize the known causes of nutrient deficiencies and the mechanism of IBD-associated diarrhea. We also overview the consequences of impaired epithelial transport, which infrequently transcend its primary purpose to affect the gut microbial ecology and epithelial integrity. While some of those regulatory mechanisms are relatively well established, more work needs to be done to determine how inflammatory cytokines can alter the transport process of nutrients across the gastrointestinal and renal epithelia.

    Peroxiredoxins (PRDXs) are antioxidant enzymes, known to catalyze peroxide reduction to balance cellular hydrogen peroxide (H2O2) levels, which are essential for cell signaling and metabolism and act as a regulator of redox signaling. Redox signaling is a critical component of cell signaling pathways that are involved in the regulation of cell growth, metabolism, hormone signaling, immune regulation and variety of other physiological functions. Early studies demonstrated that PRDXs regulates cell growth, metabolism and immune regulation and therefore involved in the pathologic regulator or protectant of several cancers, neurodegenerative diseases and inflammatory diseases. Oxidative stress and antioxidant systems are important regulators of redox signaling regulated diseases. In addition, thiol-based redox systems through peroxiredoxins have been demonstrated to regulate several redox-dependent process related diseases. In this review article, we will discuss recent findings regarding PRDXs in the development of diseases and further discuss therapeutic approaches targeting PRDXs. Moreover, we will suggest that PRDXs could be targets of several diseases and the therapeutic agents for targeting PRDXs may have potential beneficial effects for the treatment of cancers, neurodegenerative diseases and inflammatory diseases. Future research should open new avenues for the design of novel therapeutic approaches targeting PRDXs. PMID:27130805

    Background: Non-Inflammatory Destructive Periodontal Disease (NIDPD), is a severe destructive periodontal disease, that is characterized by the attachment loss and alveolar bone loss, without signs of the gingival inflammation, and the periodontal pocket development. Objective: Despite the fact that various cases of NIDPD have been reported; their etiology and disease evolution is still indefinite, and therefore, are open for discussion. Method: An NIDPD case was studied in order to demonstrate features of the disease, and discuss the possible etiology and treatment. Results: In this clinical case, the etiology of NIDPD seems to be an association of endogenous opportunist bacteria with anatomical aspects, occlusion pattern, emotional stress and mouth breathing condition. Conclusion: In spite of all cases described in the literature are comparable and may have similar etiology as related in this clinical case, additional research is needed to identify and clarify the role of the etiologic factors which determine the disease.

    Inflammatory Bowel Disease (IBD) represents a group of idiopathic disorders characterized by chronic or recurring inflammation of the gastrointestinal tract. While the exact etiology of disease is unknown, IBD is recognized to be a complex, multifactorial disease that results from an intricate interplay of genetic predisposition, an altered immune response, changes in the intestinal microbiota, and environmental factors. Together, these contribute to a destruction of the intestinal epithelial barrier, increased gut permeability, and an influx of immune cells. Given that most cellular functions as well as maintenance of the epithelial barrier is energy-dependent, it is logical to assume that mitochondrial dysfunction may play a key role in both the onset and recurrence of disease. Indeed several studies have demonstrated evidence of mitochondrial stress and alterations in mitochondrial function within the intestinal epithelium of patients with IBD and mice undergoing experimental colitis. Although the hallmarks of mitochondrial dysfunction, including oxidative stress and impaired ATP production are known to be evident in the intestines of patients with IBD, it is as yet unclear whether these processes occur as a cause of consequence of disease. We provide a current review of mitochondrial function in the setting of intestinal inflammation during IBD. PMID:26484345

    A specific and ultrasensitive, label free single-walled carbon nanotubes (SWNTs) based chemiresistive genosensor was fabricated for the early detection of Streptococcus pyogenes infection in human causing rheumatic heart disease. The mga gene of S. pyogenes specific 24 mer ssDNA probe was covalently immobilized on SWNT through a molecular bilinker, 1-pyrenemethylamine, using carbodiimide coupling reaction. The sensor was characterized by the current-voltage (I-V) characteristic curve and scanning electron microscopy. The sensing performance of the sensor was studied with respect to changes in conductance in SWNT channel based on hybridization of the target S. pyogenes single stranded genomic DNA (ssG-DNA) to its complementary 24 mer ssDNA probe. The sensor shows negligible response to non-complementary Staphylococcus aureus ssG-DNA, confirming the specificity of the sensor only with S. pyogenes. The genosensor exhibited a linear response to S. pyogenes G-DNA from 1 to1000 ng ml-1 with a limit of detection of 0.16 ng ml-1.

    Leukotrienes (LTs) are a family of inflammatory mediators including LTA4, LTB4, LTC4, LTD4, and LTE4. By competitive binding to the cysteinyl LT1 (CysLT1) receptor, LT receptor antagonist drugs, such as montelukast, zafirlukast, and pranlukast, block the effects of CysLTs, improving the symptoms of some chronic respiratory diseases, particularly bronchial asthma and allergic rhinitis. We reviewed the efficacy of antileukotrienes in upper airway inflammatory diseases. An update on the use of antileukotrienes in upper airway diseases in children and adults is presented with a detailed literature survey. Data on LTs, antileukotrienes, and antileukotrienes in chronic rhinosinusitis and nasal polyps, asthma, and allergic rhinitis are presented. Antileukotriene drugs are classified into two groups: CysLT receptor antagonists (zafirlukast, pranlukast, and montelukast) and LT synthesis inhibitors (5-lipoxygenase inhibitors such as zileuton, ZD2138, Bay X 1005, and MK-0591). CysLTs have important proinflammatory and profibrotic effects that contribute to the extensive hyperplastic rhinosinusitis and nasal polyposis (NP) that characterise these disorders. Patients who receive zafirlukast or zileuton tend to show objective improvements in, or at least stabilisation of, NP. Montelukast treatment may lead to clinical subjective improvement in NP. Montelukast treatment after sinus surgery can lead to a significant reduction in eosinophilic cationic protein levels in serum, with a beneficial effect on nasal and pulmonary symptoms and less impact in NP. Combined inhaled corticosteroids and long-acting β-agonists treatments are most effective for preventing exacerbations among paediatric asthma patients. Treatments with medium- or high-dose inhaled corticosteroids, combined inhaled corticosteroids and LT receptor antagonists, and low-dose inhaled corticosteroids have been reported to be equally effective. Antileukotrienes have also been reported to be effective for allergic

    Anemia is a common extraintestinal manifestation of inflammatory bowel disease (IBD) and is frequently overlooked as a complication. Patients with IBD are commonly found to have iron deficiency anemia (IDA) secondary to chronic blood loss, and impaired iron absorption due to tissue inflammation. Patients with iron deficiency may not always manifest with signs and symptoms; so, hemoglobin levels in patients with IBD must be regularly monitored for earlier detection of anemia. IDA in IBD is associated with poor quality of life, necessitating prompt diagnosis and appropriate treatment. IDA is often associated with inflammation in patients with IBD. Thus, commonly used laboratory parameters are inadequate to diagnose IDA, and newer iron indices, such as reticulocyte hemoglobin content or percentage of hypochromic red cells or zinc protoporphyrin, are required to differentiate IDA from anemia of chronic disease. Oral iron preparations are available and are used in patients with mild disease activity. These preparations are inexpensive and convenient, but can produce gastrointestinal side effects, such as abdominal pain and diarrhea, that limit their use and patient compliance. These preparations are partly absorbed due to inflammation. Non-absorbed iron can be toxic and worsen IBD disease activity. Although cost-effective intravenous iron formulations are widely available and have improved safety profiles, physicians are reluctant to use them. We present a review of the pathophysiologic mechanisms of IDA in IBD, improved diagnostic and therapeutic strategies, efficacy, and safety of iron replacement in IBD. PMID:26301120

    Chronic illnesses such as inflammatory bowel disease (IBD) present a unique opportunity to define and improve the quality of care. Processes of care can be complex, and outcomes of care may vary across different healthcare delivery settings. Patients with IBD are managed over long periods of time and often by the same physician within a single care delivery system. Both patients with Crohn’s disease and ulcerative colitis have variable courses of disease progression that require changes in therapy over time. These factors necessitate multiple areas of potential assessment and improvement of processes and outcomes of care. A current initiative is the development of quality measures. The American Gastroenterological Association has developed accountability measures for the Physician Quality Reporting System, and the Crohn’s and Colitis Foundation of America has developed a set of top 10 recommended processes and outcomes of measurement for high-quality care of patients with IBD. In addition, the pediatric ImproveCareNow collaborative network has collected improvement data from dozens of pediatric centers over the past 5 years and has demonstrated improvement in overall disease activity in their cohort through iterative quality improvement processes. Future directions for quality indicators for adults with IBD will involve implementation of quality-measure reporting, both for purposes of reimbursement as well as improvement of care. These strategies will need to be closely monitored to evaluate the effect of improvement programs on outcomes. PMID:23943663

    2014-01-01

    Over the past decade there has been a dramatic change in the treatment of patients with Crohn’s disease and ulcerative colitis, which comprise the inflammatory bowel diseases (IBD). This is due to the increasing use of immunosuppressives and in particular the biological agents, which are being used earlier in the course of disease, and for longer durations, as these therapies result in better clinical outcomes for patients. This, however, has the potential to increase the risk of opportunistic and serious infections in these patients, most of which are preventable. Much like the risk for potential malignancy resulting from the use of these therapies long-term, a balance needs to be struck between medication use to control the disease with minimization of the risk of an opportunistic infection. This outcome is achieved by the physician’s tailored use of justified therapies, and the patients’ education and actions to minimize infection risk. The purpose of this review is to explore the evidence and guidelines available to all physicians managing patients with IBD using immunomodulating agents and to aid in the prevention of opportunistic infections.

    Chorea gravidarum is a rare movement disorder of pregnancy with a broad differential diagnosis. Although often a benign condition, it may indicate underlying acute rheumatic fever, antiphospholipid antibody syndrome or a hypercoagulable state. However, now that rheumatic fever is rare in western countries, chorea gravidarum occurs most commonly in patients with chronic rheumatic heart disease. Heightened awareness of chorea gravidarum and the morbidity of the often associated rheumatic heart disease, particularly in immigrants from developing countries, is essential for early diagnosis and effective management. A case of chorea gravidarum in a woman with rheumatic mitral stenosis is described. The diagnostic approach, pathophysiology and management of this rare condition are discussed. PMID:12772024

    Abstract: Extraintestinal manifestations (EIM) in inflammatory bowel disease (IBD) are frequent and may occur before or after IBD diagnosis. EIM may impact the quality of life for patients with IBD significantly requiring specific treatment depending on the affected organ(s). They most frequently affect joints, skin, or eyes, but can also less frequently involve other organs such as liver, lungs, or pancreas. Certain EIM, such as peripheral arthritis, oral aphthous ulcers, episcleritis, or erythema nodosum, are frequently associated with active intestinal inflammation and usually improve by treatment of the intestinal activity. Other EIM, such as uveitis or ankylosing spondylitis, usually occur independent of intestinal inflammatory activity. For other not so rare EIM, such as pyoderma gangrenosum and primary sclerosing cholangitis, the association with the activity of the underlying IBD is unclear. Successful therapy of EIM is essential for improving quality of life of patients with IBD. Besides other options, tumor necrosis factor antibody therapy is an important therapy for EIM in patients with IBD. PMID:26154136

    Inflammatory bowel disease (IBD) is characterized by chronic inflammation of the intestine that compromises the patients' life quality and requires sustained pharmacological and surgical treatments. Since their etiology is not completely understood, non-fully-efficient drugs have been developed and those that have shown effectiveness are not devoid of quite important adverse effects that impair their long-term use. In this regard, a growing body of evidence confirms the health benefits of flavonoids. Flavonoids are compounds with low molecular weight that are widely distributed throughout the vegetable kingdom, including in edible plants. They may be of great utility in conditions of acute or chronic intestinal inflammation through different mechanisms including protection against oxidative stress, and preservation of epithelial barrier function and immunomodulatory properties in the gut. In this review we have revised the main flavonoid classes that have been assessed in different experimental models of colitis as well as the proposed mechanisms that support their beneficial effects.

    Some form of imaging procedure should be used to document the presence of infection of the upper urinary tract in troublesome cases in children. During the past several years, sonography, nuclear radiology, and computed tomography (CT) have had a significant influence on renal imaging. The purpose of this article is to reevaluate the noninvasive imaging procedures that can be used to diagnose pediatric renal inflammatory disease and to assess the relative value of each modality in the various types of renal infection. The authors will not discuss the radiologic evaluation of the child who has had a previous renal infection, in whom cortical scarring or reflux nephropathy is a possibility; these are different clinical problems and require different diagnostic evaluation.

    Ten women with tubo-ovarian abscess caused by pelvic inflammatory disease (PID) were investigated by transvaginal Doppler ultrasound during the acute and healing phases of the infection. The pulsatility index (PI) of the uterine arteries was measured and compared with the values obtained from 19 healthy women. Each control patient was investigated three times during a single menstrual cycle. In PID patients, the PI values were significantly lower than in controls in the same phase of the menstrual cycle. When C-reactive protein was > 50, the PI values were lowest and reverted to normal values when the infection subsided. In a case of chronic infection, the PI did not rise to normal despite normal infection parameters. Doppler ultrasound seems to offer a new method of assessing PID. PMID:1487185

    2010-01-01

    Thiopurines are widely used in the treatment of inflammatory bowel disease (IBD). However, in clinical practice azathioprine (AZA) or 6-mercaptopurine (6-MP) are not effective in one-third of patients and up to one-fifth of patients discontinue thiopurine therapy due to adverse reactions. The observed interindividual differences in therapeutic response and toxicity to thiopurines are explained to a large extent by the variable formation of active metabolites, which is at least partly caused by genetic polymorphisms of the genes encoding crucial enzymes in thiopurine metabolism. In this in-depth review we discuss the genetic polymorphisms of genes encoding for glutathione S-tranferases, xanthine oxidase, thiopurine S-methyltransferase, inosine triphosphate pyrophosphatase, hypoxanthine phosphoribosyltransferase, inosine monophosphate dehydrogenase and multidrug resistance proteins. Pharmacogenetic knowledge in this field has increased dramatically and is still rapidly increasing, but the translation into practical guidelines with tailored advices will cost much effort in the near future.

    Pelvic inflammatory disease (PID) is a serious public health and reproductive health problem in the United States. An early and accurate diagnosis of PID is extremely important for the effective management of the acute illness and for the prevention of long-term sequelae. The diagnosis of PID is difficult, with considerable numbers of false-positive and false-negative diagnoses. An abnormal vaginal discharge or evidence of lower genital tract infection is an important and predictive finding that is often underemphasized and overlooked. This paper reviews the clinical diagnosis and supportive laboratory tests for the diagnosis of PID and outlines an appropriate diagnostic plan for the clinician and the researcher. PMID:18475365

    Patients with inflammatory bowel disease (IBD) have a greater risk for developing venous thromboembolism (VTE). Patients admitted to the hospital with IBD flares often require insertion of long-term venous access devices, such as peripherally inserted central catheters (PICCs), to provide access for medications, blood draws, fluid management, and nutrition. PICCs have been associated with an increased risk for upper extremity deep vein thrombosis. In this case study analysis, 2 patients with IBD and PICCs who developed VTE are examined. The case report includes a thorough discussion of medical history, symptomology, PICC insertion, and events leading to VTE development. A review of acquired risk factors for IBD patients and a comparison of risk factors that predisposed each to VTE are explored. These cases highlight the need for nurses and physicians to heighten surveillance and engage in proactive strategies to prevent VTE in this population of patients. PMID:27074991

    Patients with long-standing inflammatory bowel disease have an increased risk of developing colorectal cancer (CRC). CRC risk increases with longer duration of colitis, greater anatomic extent of colitis, the presence of primary sclerosing cholangitis, family history of CRC and severity of inflammation of the colon. Chemoprevention includes aminosalicylates, ursodeoxycholic acid, and possibly folic acid. To reduce CRC mortality in IBD, colonoscopic surveillance remains the major way to detect early mucosal dysplasia. When dysplasia is confirmed, proctocolectomy is considered for these patients. Ulcerative colitis patients with total proctocolectomy and ileal pouch anal-anastomosis have a rather low risk of dysplasia in the ileal pouch, but the anal transition zone should be monitored periodically. New endoscopic and molecular screening approaches may further refine our current surveillance guidelines and our understanding of the natural history of dysplasia. PMID:20485613

    Extraintestinal manifestations occur in about one-third of patients living with inflammatory bowel disease (IBD) and may precede the onset of gastrointestinal symptoms by many years. Neurologic disorders associated with IBD are not frequent, being reported in 3% of patients, but they often represent an important cause of morbidity and a relevant diagnostic issue. In addition, the increasing use of immunosuppressant and biological therapies for IBD may also play a pivotal role in the development of neurological disorders of different type and pathogenesis. Hence, we provide a complete and profound review of the main features of neurological complications associated with IBD, with particular reference to those related to drugs and with a specific focus on their clinical presentation and possible pathophysiological mechanisms.

    cAMP-specific phosphodiesterase type 4 (PDE4) is one of the hot targets for treatment of inflammatory diseases. PDE4 inhibitors can suppress inflammation by increasing the concentration of cAMP in inflammatory cells. The efficacy and safety evaluations of several PDE4 inhibitors are currently carried on in clinical trials, for example GSK256066 in asthma, roflumilast and GSK256066 in chronic obstructive pulmonary disease, tetomilast in inflammatory bowel disease, and apremilast in dermatitis and arthritis etc. This article reviews the recent progress on PDE4-targeted therapy for inflammatory diseases.

    Recent findings demonstrate the common genetic basis for many immune-mediated diseases, and consequently, the partially shared pathogenesis. We collected these findings and reviewed the extension of these overlaps to other disease characteristics. Two autoimmune diseases were selected that also share the specific target organ, the bowel. The etiology and immunopathogenesis of both conditions characterized by chronic intestinal inflammation, inflammatory bowel disease (IBD) and celiac disease (CeD), are not completely understood. Both are complex diseases with genetics and environment contributing to dysregulation of innate and adaptive immune responses, leading to chronic inflammation and disease. CeD constitutes a particular disease because the main environmental and genetic triggers are largely known. IBD comprises two main clinical forms, Crohn’s disease and ulcerative colitis, which most likely involve a complex interplay between some components of the commensal microbiota and other environmental factors in their origin. These multifactorial diseases encompass a broad spectrum of clinical phenotypes and ages of onset, although the clinical presentation often differs depending on childhood or adult onset, with greater heterogeneity commonly observed in adults.

    Dendritic cells (DCs) are critical in linking the innate and adaptive immune responses, which have been implicated in the pathogenesis of many immune and inflammatory diseases as well as the development of tumours. The role of DCs in the pathophysiology of lung diseases has been widely studied. However, the phenotype, subset and function of DCs in upper airways under physiological or pathological conditions remain largely undefined. Allergic rhinitis (AR) and chronic rhinosinusitis (CRS) are two important upper airway diseases with a high worldwide prevalence. Aberrant innate and adaptive immune responses have been considered to play an important role in the pathogenesis of AR and CRS. To this end, understanding the function of DCs in shaping the immune responses in sinonasal mucosa is critical in exploring the pathogenic mechanisms underlying AR and CRS as well as in developing novel therapeutic strategies. This review summarizes the phenotype, subset, function and regulation of DCs in sinonasal mucosa, particularly in the setting of AR and CRS. Furthermore, this review discusses the perspectives for future research and potential clinical utility focusing on DC pathways in the context of AR and CRS. PMID:27159777

    The intestinal microbiota has important metabolic and host-protective functions. Conversely to these beneficial functions, the intestinal microbiota is thought to play a central role in the etiopathogenesis of inflammatory bowel disease (IBD; Crohn's disease and ulcerative colitis), a chronic inflammation of the gut mucosa. Genetic screens and studies in experimental mouse models have clearly demonstrated that IBD can develop due to excessive translocation of bacteria into the bowel wall or dysregulated handling of bacteria in genetically susceptible hosts. In healthy individuals, the microbiota is efficiently separated from the mucosal immune system of the gut by the gut barrier, a single layer of highly specialized epithelial cells, some of which are equipped with innate immune functions to prevent or control access of bacterial antigens to the mucosal immune cells. It is currently unclear whether the composition of the microbial flora or individual bacterial strains or pathogens induces or supports the pathogenesis of IBD. Further research will be necessary to carefully dissect the contribution of individual bacterial species to this disease and to ascertain whether specific modulation of the intestinal microbiome may represent a valuable further option for future therapeutic strategies.

    This study aimed to estimate the prevalence of musculoskeletal disorders and rheumatic diseases in the Warao, Kari'ña, and Chaima indigenous populations of Monagas State, Venezuela. A cross-sectional, analytical, community-based study was conducted in 1537 indigenous subjects ≥18 years old (38.6 % male, mean age 41.4 ± 17.5 years). The cross-culturally validated Community Oriented Program for the Control of Rheumatic Diseases (COPCORD) diagnostic questionnaire was applied. Subjects with a positive COPCORD diagnosis (either historic or current pain) were evaluated by primary care physicians and rheumatologists. A descriptive analysis was performed and comparisons made using analysis of variance and the chi-square test. Pain in the last 7 days was reported by 32.9 %, with pain intensity, according to a Likert-type scale [no pain, 195 (38.5 %); minimal pain, 231 (45.6 %); strong pain, 68 (13.4 %); intense pain, 5 (0.9 %)], 38.0 % reported historical pain, and 641 (41.7 %) had either historic or current pain. Of the COPCORD-positive subjects, pain most frequently occurred in the knee, back, and hands. Musculoskeletal and rheumatic diseases included osteoarthritis (14.1 %), back pain (12.4 %), rheumatic regional pain syndromes (RRPS) (9.7 %), undifferentiated arthritis (1.5 %), rheumatoid arthritis (1.1 %), and fibromyalgia (0.5 %). Chaima (18.3 %) and Kari'ña (15.6 %) subjects had a high prevalence of osteoarthritis, and Warao subjects had a high prevalence of low back pain (13.8 %). The prevalence of RRPS was high in all three ethnic groups. The Chaima group had the highest prevalence of rheumatic diseases, with 2.0 % having rheumatoid arthritis. This study provides useful information for health care policy-making in indigenous communities. PMID:26895629

    The most common extra-intestinal manifestation in patients with inflammatory bowel disease (IBD) is articular involvement, with a prevalence ranging between 17% and 39%. It is frequently characterized by an involvement of the axial joints but may also be associated with peripheral arthritis. The target of therapy in the management of arthritis associated with IBD is to reduce the inflammation and prevent any disability and/or deformity. This requires active cooperation between gastroenterologist and rheumatologist. The treatment of axial involvement has focused on the combination of exercise with nonsteroidal anti-inflammatory drugs. Immunomodulators have been efficacious in patients with peripheral arthritis and other extra-intestinal manifestations, but they are not effective for the treatment of axial symptoms of spondylitis. Tumor necrosis factor (TNF) α inhibitors have been proven to be highly effective in the treatment of IBD patients which are steroid-dependent or refractory to conventional therapy and in patients with associated articular manifestations. The treatment of peripheral involvement and/or enthesitis and/or dactylitis is based on local steroid injections, while sulfasalazine and/or low doses of systemic steroids may be useful in case of inadequate response to intra-articular steroids. Sulfasalazine induces only a little improvement in peripheral arthritis. Immunomodulators such as methotrexate, azathioprine, cyclosporine and leflunomide show their efficacy in some patients with peripheral arthritis and other extra-intestinal components. TNF-α inhibitors should be considered the first-line therapeutic approach when moderate-to-severe luminal Crohn’s disease or ulcerative colitis is associated with polyarthritis. The aim of this review is to provide a fair summary of current treatment options for the arthritis associated with IBD. PMID:25729557

    Inflammatory bowel diseases (IBD) constitute a group of chronic intestinal diseases, including Crohn's disease and ulcerative colitis, which typically involve patients of reproductive age and may influence several features of human reproduction. There are many concerns regarding the interactions between the course of IBD, applied treatment (pharmacological or surgical), and fertility, reproductive outcomes, and also neonatal outcomes. To review the literature describing fertility in IBD patients (separately for female and male), and possible infertility treatment in this group of patients, a PubMed search for English only publications (articles and/or abstracts) was conducted. Initially, the titles of publications and their abstracts were screened, and the most appropriate articles were selected and reviewed. Overall, in patients with quiescent IBD, fertility is almost identical to the general population, but particular subgroups of patients (with active disease, on pharmacological treatment, and after pelvic or abdominal surgery) may be affected by reduced fertility. Additionally, patients with IBD have fewer children than the general population, mainly as a result of voluntary childlessness. The main objectives for successful reproductive outcomes in IBD patients are proper guidance and also optimal treatment for achieving and maintaining disease remission. Recently, the European Evidence-Based Consensus on Reproduction and Pregnancy in IBD (the European Crohn's and Colitis Organization Guidelines) has been established to optimize preconceptional counseling and to promote an appropriate clinical management for patients planning to conceive. However, further studies are needed regarding the preservation of fertility in IBD patients and introduction of optimal infertility treatment in this group of patients. PMID:27117378

    Disease modifying antirheumatic drugs (DMARDs) are widely used and well accepted for the treatment of patients with rheumatoid arthritis (RA). Many studies have been performed with monotherapy and combinations of DMARDs showing their efficacy and safety. In ankylosing spondylitis (AS) DMARDs, sulfasalazine especially, are recommended only for the peripheral involvement and not for the axial symptoms. For this disease there is a lack of clinical trials and most of the trials did not show efficacy on the axial symptoms of the disease.

    The management of patients with chronic conditions, such as inflammatory bowel disease (IBD), requires specific attention and careful planning during the transition from pediatric to adult care. Early education about the transition process and the acquisition of self-management skills are crucial to fostering independent adolescents and young adults who have the knowledge and tools to manage life with a chronic disease. A growing body of literature describes the challenges and barriers to providing adolescent and transition care. Potential barriers to effective transition include the following: differences between adult- and pediatric-onset IBD; patients’ lack of developmental maturity and readiness, self-efficacy, and knowledge of the disease; poor adherence to therapy; adolescent anxiety and depression; differences between pediatric and adult IBD care; and parental and provider reluctance to transition. Despite our ability to identify barriers and challenges, there remain significant gaps in our knowledge about how they should be addressed. Outcomes data on adolescents with IBD are limited, and there are even fewer data on how the transition of care affects long-term treatment and outcomes. More research is needed to truly understand the best way to facilitate care during transition and improve outcomes. Current research and transition guidelines acknowledge that providing support and guidance to patients and their families and establishing clear goals can ultimately equip patients with the skills needed to cope with a chronic disease as adults and can improve their long-term care. This paper provides an overview of the transition from pediatric to adult IBD care, a discussion of challenges and barriers, and recommendations and resources that can help patients, parents, and providers navigate this important process.

    Rett syndrome (RTT) is a pervasive neurodevelopmental disorder mainly linked to mutations in the gene encoding the methyl-CpG-binding protein 2 (MeCP2). Respiratory dysfunction, historically credited to brainstem immaturity, represents a major challenge in RTT. Our aim was to characterize the relationships between pulmonary gas exchange abnormality (GEA), upper airway obstruction, and redox status in patients with typical RTT (n = 228) and to examine lung histology in a Mecp2-null mouse model of the disease. GEA was detectable in ~80% (184/228) of patients versus ~18% of healthy controls, with “high” (39.8%) and “low” (34.8%) patterns dominating over “mixed” (19.6%) and “simple mismatch” (5.9%) types. Increased plasma levels of non-protein-bound iron (NPBI), F2-isoprostanes (F2-IsoPs), intraerythrocyte NPBI (IE-NPBI), and reduced and oxidized glutathione (i.e., GSH and GSSG) were evidenced in RTT with consequently decreased GSH/GSSG ratios. Apnea frequency/severity was positively correlated with IE-NPBI, F2-IsoPs, and GSSG and negatively with GSH/GSSG ratio. A diffuse inflammatory infiltrate of the terminal bronchioles and alveoli was evidenced in half of the examined Mecp2-mutant mice, well fitting with the radiological findings previously observed in RTT patients. Our findings indicate that GEA is a key feature of RTT and that terminal bronchioles are a likely major target of the disease. PMID:24757286

    Inflammatory bowel disease (IBD) predominantly affects young adults. Fertility-related issues are therefore important in the management of patients with IBD. However, relatively modest attention has been paid to reproductive issues faced by men with IBD. To investigate the effects of IBD and its treatment on male fertility, we reviewed the current literature using a systematic search for published studies. A PubMed search were performed using the main search terms “IBD AND male infertility”, “Crohn’s disease AND male infertility”, “ulcerative colitis AND male infertility”. References in review articles were used if relevant. We noted that active inflammation, poor nutrition, alcohol use, smoking, medications, and surgery may cause infertility in men with IBD. In surgery such as proctocolectomy with ileal pouch-anal anastomosis, rectal incision seems to be associated with sexual dysfunction. Of the medications used for IBD, sulfasalazine reversibly reduces male fertility. No other medications appear to affect male fertility significantly, although small studies suggested some adverse effects. There are limited data on the effects of drugs for IBD on male fertility and pregnancy outcomes; however, patients should be informed of the possible effects of paternal drug exposure. This review provides information on fertility-related issues in men with IBD and discusses treatment options. PMID:27602237

    Investigation of the possible role of Campylobacter concisus (C. concisus) in inflammatory bowel disease (IBD) is an emerging research area. Despite the association found between C. concisus and IBD, it has been difficult to explain how C. concisus, a bacterium that is commonly present in the human oral cavity, may contribute to the development of enteric diseases. The evidence presented in this review shows that some C. concisus strains in the oral cavity acquired zonula occludens toxin (zot) gene from a virus (prophage) and that C. concisus Zot shares conserved motifs with both Vibrio cholerae Zot receptor binding domain and human zonulin receptor binding domain. Both Vibrio cholerae Zot and human zonulin are known to increase intestinal permeability by affecting the tight junctions. Increased intestinal permeability is a feature of IBD. Based on these data, we propose that a primary barrier function defect caused by C. concisus Zot is a mechanism by which zot-positive C. concisus strains may trigger the onset and relapse of IBD.

    2013-01-01

    Background Knowledge of factors that contribute to non-persistence with disease modifying anti-rheumatic drugs (NP) is essential to improve rheumatoid arthritis (RA) outcomes. Aims of the study were to investigate patient’s motivations and risk factors for NP in a cohort of early RA patients. Methods Up to September 2012, data from 149 patients, who had at least 1 year of follow-up, at least one drug indication, and at least 2 consecutive six-months-apart rheumatic evaluations that included assessment of compliance were reviewed. NP and patient’s motivations of NP were evaluated according to a questionnaire. NP was defined when patients referred that they had completely stop RA medication, “Sometimes”, “Almost always” or “Always”. Patients had to pay for their medication. Descriptive statistics and logistic regression models were used. Statistical significance was set at a p value of less than 0.05. The study was approved by the internal review board. Results Up to cut-off, 715 questionnaires were applied to 149 patients, who had follow-up of 58.7 ± 27.9 months and were indicated 2.4 ± 0.7 DMARDs/patient/follow-up. Patients were most frequently female (88.6%), middle-aged ([mean ± SD] age of 38.5 ± 12.8 years) with lower-middle/lower socio-economic status (87.9%) and scholarship of 11 ± 3.9 years. Ninety-nine (66.4%) patients were NP and filled 330 questionnaires. Multivariate analysis showed that years of formal education (OR: 1.12, 95% CI: 1.1-1.24, p = 0.03), perception of at least some difficulty to find arthritis medication (OR: 5.68, 95% CI: 2.48-13, p = 0.000) and perception that arthritis medication is expensive (OR: 5.27, 95% CI: 2.1-13.84, p = 0.001) at the first evaluation of patient’s compliance were all predictors of NP. Among the 99 NP patients, 25 (25.3%) were recurrent-NP and accumulated more disease activity. The combination of both reasons of NP (“Because it was not available at the

    Serological biomarkers in inflammatory bowel disease (IBD) are a rapidly expanding list of non-invasive tests for objective assessments of disease activity, early diagnosis, prognosis evaluation and surveillance. This review summarizes both old and new biomarkers in IBD, but focuses on the development and characterization of new serological biomarkers (identified since 2007). These include five new anti-glycan antibodies, anti-chitobioside IgA (ACCA), anti-laminaribioside IgG (ALCA), anti-manobioside IgG (AMCA), and antibodies against chemically synthesized (Σ) two major oligomannose epitopes, Man α-1,3 Man α-1,2 Man (ΣMan3) and Man α-1,3 Man α-1,2 Man α-1,2 Man (ΣMan4). These new biomarkers serve as valuable complementary tools to existing biomarkers not only in differentiating Crohn’s disease (CD), ulcerative colitis (UC), normal and other non-IBD gut diseases, but also in predicting disease involvement (ileum vs colon), IBD risk (as subclinical biomarkers), and disease course (risk of complication and surgery). Interestingly, the prevalence of the antiglycan antibodies, including anti-Saccharomyces cerevisiae antibodies (ASCA), ALCA and AMCA, was found to be associated with single nucleotide polymorphisms (SNPs) of IBD susceptible genes such as NOD2/CARD15, NOD1/CARD4, toll-like receptors (TLR) 2 and 4, and β-defensin-1. Furthermore, a gene dosage effect was observed: anti-glycan positivity became more frequent as the number of NOD2/CARD15 SNPS increased. Other new serum/plasma IBD biomarkers reviewed include ubiquitination factor E4A (UBE4A), CXCL16 (a chemokine), resistin, and apolipoprotein A-IV. This review also discusses the most recent studies in IBD biomarker discovery by the application of new technologies such as proteomics, fourier transform near-infrared spectroscopy, and multiplex enzyme-linked immunosorbent assay (ELISA)’s (with an emphasis on cytokine/chemokine profiling).

    Objectives Antigen-specific CD4+ T cells epigenetically modified with DNA methylation inhibitors overexpress genes normally suppressed by this mechanism, including CD11a, CD70, CD40L and the KIR gene family. The altered cells become autoreactive, losing restriction for nominal antigen and responding to self-class II major histocompatibility complex (MHC) molecules without added antigen, and are sufficient to cause a lupus-like disease in syngeneic mice. T cells overexpressing the same genes are found in patients with active lupus. Whether these genes are co-overexpressed on the same or different cells is unknown. The goal of this study was to determine whether these genes are overexpressed on the same or different T cells and whether this subset of CD4+ T cells is also present in patients with lupus and other rheumatic diseases. Methods Multicolour flow cytometry was used to compare CD11a, CD70, CD40L and KIR expression on CD3+CD4+CD28+ T cells to their expression on experimentally demethylated CD3+CD4+CD28+ T cells and CD3+CD4+CD28+ T cells from patients with active lupus and other autoimmune diseases. Results Experimentally demethylated CD4+ T cells and T cells from patients with active lupus have a CD3+CD4+CD28+CD11ahiCD70+CD40LhiKIR+ subset, and the subset size is proportional to lupus flare severity. A similar subset is found in patients with other rheumatic diseases including rheumatoid arthritis, systemic sclerosis and Sjögren's syndrome but not retroperitoneal fibrosis. Conclusions Patients with active autoimmune rheumatic diseases have a previously undescribed CD3+CD4+CD28+CD11ahiCD70+CD40LhiKIR+ T cell subset. This subset may play an important role in flares of lupus and related autoimmune rheumatic diseases, provide a biomarker for disease activity and serve as a novel therapeutic target for the treatment of lupus flares.

    Rheumatic and musculoskeletal diseases (RMD) are prevalent and leading causes of disability and consumption of healthcare and social resources. EpiReumaPt is a national population-based survey developed by the Portuguese Society of Rheumatology that aimed to estimate the prevalence of RMDs and determine their impact on function, quality of life, mental health and use of healthcare resources. This article describes in detail the design, methodology and planned analyses of EpiReumaPt. Recruitment started in September 2011 and finished in December 2013. This study involved a three-stage approach. The first step was a face-to-face survey performed by trained interviewers at the household of 10,661 subjects who where randomly selected by a stratified multistage sampling. A highly sensitive screening questionnaire for RMDs was used. Secondly, participants who screened positive (64%) for at least one RMD as well as 20% of individuals with a negative screening were invited for assessment by a rheumatologist. In total, 3,877 subjects participated in this second phase, where they were also invited to donate a blood sample to be stored at the Biobanco-IMM. History and physical examination, followed by appropriate laboratory and imaging tests were performed. At the end of the visit, the rheumatologist established a diagnosis. Finally, a team of three experienced rheumatologists reviewed all the clinical data and defined the diagnoses according to previously validated criteria. The EpiReumaPt dataset, containing data from several questionnaires, various clinical measurements and information from laboratory and imaging tests, comprises an invaluable asset for research. The large amount of information collected from each participant and the large number of participants, with a wide age range covering and being representative of the adults from the entire country, makes EpiReumaPt the largest study of RMDs performed in Portugal.

    The ability to integrate echocardiographic for rheumatic heart disease (RHD) into RHD prevention programs is limited because of lack of financial and expert human resources in endemic areas. Task shifting to nonexperts is promising; but investigations into workforce composition and training schemes are needed. The objective of this study was to test nonexperts' ability to interpret RHD screening echocardiograms after a brief, standardized, computer-based training course. Six nonexperts completed a 3-week curriculum on image interpretation. Participant performance was tested in a school-screening environment in comparison to the reference approach (cardiologists, standard portable echocardiography machines, and 2012 World Heart Federation criteria). All participants successfully completed the curriculum, and feedback was universally positive. Screening was performed in 1,381 children (5 to 18 years, 60% female), with 397 (47 borderline RHD, 6 definite RHD, 336 normal, and 8 other) referred for handheld echo. Overall sensitivity of the simplified approach was 83% (95% CI 76% to 89%), with an overall specificity of 85% (95% CI 82% to 87%). The most common reasons for false-negative screens (n = 16) were missed mitral regurgitation (MR; 44%) and MR ≤1.5 cm (29%). The most common reasons for false-positive screens (n = 179) included identification of erroneous color jets (25%), incorrect MR measurement (24%), and appropriate application of simplified guidelines (39.4%). In conclusion, a short, independent computer-based curriculum can be successfully used to train a heterogeneous group of nonexperts to interpret RHD screening echocardiograms. This approach helps address prohibitive financial and workforce barriers to widespread RHD screening. PMID:27084054

    Our goal in the present work was to determine whether male patients with untreated hypogonadism have an increased risk of developing rheumatic/autoimmune disease (RAD), and, if so, whether there is a relation to the type of hypogonadism. We carried out neuroendocrine, genetic, and rheumatologic investigations in 13 such patients and 10 healthy male 46,XY normogonadic control subjects. Age and body mass index were similar in the two groups. Nine of the 13 patients had hypergonadotropic hypogonadism (five of whom had Klinefelter's syndrome [karyotype 47,XXY]) and 4 of the 13 had hypogonadotropic hypogonadism (46,XY). Of these last four, two had Kallmann's syndrome and two had idiopathic cryptorchidism. Eight (61%) of the 13 patients studied had RADs unrelated to the etiology of their hypogonadism. Of these, four had ankylosing spondylitis and histocompatibility B27 antigen, two had systemic lupus erythematosus (in one case associated with antiphospholipids), one had juvenile rheumatoid arthritis, and one had juvenile dermatomyositis. In comparison with the low frequencies of RADs in the general population (about 0.83%, including systemic lupus erythematosus, 0.03%; dermatomyositis, 0.04%; juvenile rheumatoid arthritis, 0.03%; ankylosing spondylitis, 0.01%; rheumatoid arthritis, 0.62%; and other RAD, 0.1%), there were surprisingly high frequencies of such disorders in this small group of patients with untreated hypogonadism (P < 0.001) and very low serum testosterone levels (P = 0.0005). The presence of RADs in these patients was independent of the etiology of their hypogonadism and was associated with marked gonadal failure with very low testosterone levels. PMID:11714390

    Purpose To define importance values assigned to attributes of biological agents (BAs) by Spanish patients with rheumatic diseases (rheumatoid arthritis, ankylosing spondylitis, and psoriatic arthritis) and rheumatologists. Patients and methods This was an observational, cross-sectional design based upon a rank-based full-profile conjoint analysis. A literature review and four focus groups were undertaken to identify attributes and levels. An orthogonal matrix, combining the selected levels of attributes, was used to define scenarios. Participants ranked eight scenarios from 1 (most preferred) to 8 (least preferred). The relative importance (RI) of attributes was calculated. Multivariate regression analysis was performed to identify the characteristics that influenced the values of RI. A total of 488 patients (male 50.9%, mean age 50.6 [standard deviation {SD} 12.06] years, rheumatoid arthritis 33.8%, ankylosing spondylitis 32.4%, psoriatic arthritis 33.8%; mean time since diagnosis 12.6 [SD 8.2] years) and 136 rheumatologists (male 50.4%, mean age 46.4 [SD 9.1] years, mean time of practice 16.7 [SD 8.8] years) participated. Results The ideal BAs for patients and physicians, respectively, should allow pain relief and improvement of functional capacity (RI 39% and 44.7%), with low risk of adverse events (RI 24.9% and 30.5%), a long time prior to perceiving the need for a new dose (RI 16.4% and 12.4%), and self-administration at home (RI 19.7% and 12.5%), as identified through their preferences. Conclusion Although efficacy and safety are paramount for patients and rheumatologists to make a choice regarding BAs, the need for a low frequency of administration and the administration method also play a role as preference attributes for BAs.

  6. Inflammatory Bowel Disease: Genetics, Epigenetics, and Pathogenesis

    PubMed Central

    Loddo, Italia; Romano, Claudio

    2015-01-01

    Inflammatory bowel diseases (IBDs) are complex, multifactorial disorders characterized by chronic relapsing intestinal inflammation. Although etiology remains largely unknown, recent research has suggested that genetic factors, environment, microbiota, and immune response are involved in the pathogenesis. Epidemiological evidence for a genetic contribution is defined: 15% of patients with Crohn’s Disease (CD) have an affected family member with IBD, and twin studies for CD have shown 50% concordance in monozygotic twins compared to <10% in dizygotics. The most recent and largest genetic association studies, which employed genome-wide association data for over 75,000 patients and controls, identified 163 susceptibility loci for IBD. More recently, a trans-ethnic analysis, including over 20,000 individuals, identified an additional 38 new IBD loci. Although most cases are correlated with polygenic contribution toward genetic susceptibility, there is a spectrum of rare genetic disorders that can contribute to early-onset IBD (before 5 years) or very early onset IBD (before 2 years). Genetic variants that cause these disorders have a wide effect on gene function. These variants are so rare in allele frequency that the genetic signals are not detected in genome-wide association studies of patients with IBD. With recent advances in sequencing techniques, ~50 genetic disorders have been identified and associated with IBD-like immunopathology. Monogenic defects have been found to alter intestinal immune homeostasis through many mechanisms. Candidate gene resequencing should be carried out in early-onset patients in clinical practice. The evidence that genetic factors contribute in small part to disease pathogenesis confirms the important role of microbial and environmental factors. Epigenetic factors can mediate interactions between environment and genome. Epigenetic mechanisms could affect development and progression of IBD. Epigenomics is an emerging field, and

    Background: Tricuspid regurgitation (TR) is frequently associated with severe mitral stenosis (MS), the importance of significant TR was often neglected. However, TR influences the outcome of patients. The aim of this study was to investigate the efficacy and safety of percutaneous balloon mitral valvuloplasty (PBMV) procedure in rheumatic heart disease patients with mitral valve (MV) stenosis and tricuspid valve regurgitation. Methods: Two hundred and twenty patients were enrolled in this study due to rheumatic heart disease with MS combined with TR. Mitral balloon catheter made in China was used to expand MV. The following parameters were measured before and after PBMV: MV area (MVA), TR area (TRA), atrial pressure and diameter, and pulmonary artery pressure (PAP). The patients were followed for 6 months to 9 years. Results: After PBMV, the MVAs increased significantly (1.7 ± 0.3 cm2 vs. 0.9 ± 0.3 cm2, P < 0.01); TRA significantly decreased (6.3 ± 1.7 cm2 vs. 14.2 ± 6.5 cm2, P < 0.01), right atrial area (RAA) decreased significantly (21.5 ± 4.5 cm2 vs. 25.4 ± 4.3 cm2, P < 0.05), TRA/RAA (%) decreased significantly (29.3 ± 3.2% vs. 44.2 ± 3.6%, P < 0.01). TR velocity (TRV) and TR continue time (TRT) as well as TRV × TRT decreased significantly (183.4 ± 9.4 cm/s vs. 254.5 ± 10.7 cm/s, P < 0.01; 185.7 ± 13.6 ms vs. 238.6 ± 11.3 ms, P < 0.01; 34.2 ± 5.6 cm vs. 60.7 ± 8.5 cm, P < 0.01, respectively). The postoperative left atrial diameter (LAD) significantly reduced (41.3 ± 6.2 mm vs. 49.8 ± 6.8 mm, P < 0.01) and the postoperative right atrial diameter (RAD) significantly reduced (28.7 ± 5.6 mm vs. 46.5 ± 6.3 mm, P < 0.01); the postoperative left atrium pressure significantly reduced (15.6 ± 6.1 mmHg vs. 26.5 ± 6.6 mmHg, P < 0.01), the postoperative right atrial pressure decreased significantly (13.2 ± 2.4 mmHg vs. 18.5 ± 4.3 mmHg, P < 0.01).

    Nanotechnology is a growing science that has applications in various areas of medicine. The composition of nanocarriers for drug delivery is critical to guarantee high therapeutic performance when targeting specific host sites. Applications of nanotechnology are prevalent in the diagnosis and treatment of infectious and inflammatory diseases. This review summarizes recent advancements in the application of nanotechnology to the therapy of infectious and inflammatory diseases. The major focus is on the design and fabrication of various nanomaterials, characteristics and physicochemical properties of drug-loaded nanocarriers, and the use of these nanoscale drug delivery systems in treating infectious and inflammatory diseases, such as AIDS, hepatitis, tuberculosis, melanoma, and representative inflammatory diseases. Clinical trials and future perspective of the use of nanocarriers are also discussed in detail. We hope that such a review will be valuable to researchers who are exploring nanoscale drug delivery systems for the treatment of specific infectious and inflammatory diseases.

  12. Relevance of the stroma and epithelial-mesenchymal transition (EMT) for the rheumatic diseases

    PubMed Central

    Zvaifler, Nathan J

    2006-01-01

    Epithelial-mesenchymal transition (EMT) is a term applied to the process whereby cells undergo a switch from an epithelial phenotype with tight junctions, lateral, apical, and basal membranes, and lack of mobility into mesenchymal cells that have loose interactions with other cells, are non-polarized, motile and produce an extracellular matrix. The importance of this process was initially recognized from a very early step in embryology, but more recently as a potential mechanism for the progression and spread of epithelial cancers. As the sequence of morphological changes has become understood in molecular terms, diseases characterized by alterations in stromal elements and fibrosis are being considered as examples of EMT. This review will focus on the pathogenetic features of immune-mediated renal disease, systemic sclerosis and rheumatoid arthritis that could be explained by EMT. PMID:16689999

  13. Autoantigens as Partners in Initiation and Propagation of Autoimmune Rheumatic Diseases.

    2016-05-20

    Systemic autoimmune diseases are characterized by specific targeting of a limited group of ubiquitously expressed autoantigens by the immune system. This review examines the mechanisms underlying their selection as immune targets. Initiation of autoimmune responses likely reflects the presentation of antigens with a distinct structure not previously encountered by the immune system, in a proimmune context (injury, malignancy, or infection). Causes of modified structure include somatic mutation and posttranslational modifications (including citrullination and proteolysis). Many autoantigens are components of multimolecular complexes, and some of the other components may provide adjuvant activity. Propagation of autoimmune responses appears to reflect a bidirectional interaction between the immune response and the target tissues in a mutually reinforcing cycle: Immune effector pathways generate additional autoantigen, which feeds further immune response. We propose that this resonance may be a critical principle underlying disease propagation, with specific autoantigens functioning as the hubs around which amplification occurs. PMID:26907212

    Pulmonary hemosiderosis is defined as the clinical and functional consequence of iron overload of the lungs, which usually occurs due to recurrent intra-alveolar bleeding. It can manifest as miliary mottling and should be entertained in the differential diagnosis of patients presenting with miliary nodules on chest radiography, especially those with mitral stenosis. The management of secondary pulmonary hemosiderosis secondary to valvular heart disease includes valvuloplasty and/or valve replacement. The radiological opacities may disappear with successful treatment of the underlying valvular disease in many patients. However, they may persist with no physiological impairment to the patient. Here, we present a 32-year-old man with mitral stenosis who presented with fever and miliary shadows on chest radiography, which was ultimately diagnosed as secondary pulmonary hemosiderosis.

    Background: Anti-filaggrin antibodies (AFA) are among the most specific antibodies for rheumatoid arthritis, so procedures for their detection should be included in early biological diagnoses. AFA can be detected by indirect immunofluorescence (anti-keratin antibodies, AKA) or by new enzyme immunoassays (EIA). Their comparative performance needs to be established. Objective: To compare these technical procedures to optimise the serological diagnosis of rheumatoid arthritis. Methods: Results obtained using AKA and EIA were compared in 271 sera from 140 patients with rheumatoid arthritis at various stages, 98 patients with other autoimmune diseases, and 33 healthy subjects. EIA were successively undertaken with citrullinated linear filaggrin peptide (home made EIA) or cyclic citrullinated peptide (CCP2, commercial kits). Rheumatoid factor (RF) was assessed by EIA in all patients. Results: Anti-CCP2 kits showed the best sensitivity and specificity (65% and 96%, respectively). Among the 140 patients with rheumatoid arthritis, those with very recent disease (less than six months' duration, n = 21) were studied as a separate group. In this group, the sensitivity of anti-CCP2 kits decreased to ~50%. Nevertheless this assay remained the most accurate when compared with AKA or home made EIA using linear filaggrin peptides. The combination of anti-CCP2 and RF only slightly increased the sensitivity of the diagnosis of very early rheumatoid arthritis. Conclusions: Kits using citrullinated cyclic peptides (CCP2) were more suitable than either AKA or EIA using linear filaggrin peptides for the diagnosis of early rheumatoid disease. PMID:15020336

  16. The treatment of pelvic inflammatory disease.

    The treatment of pelvic inflammatory disease depends upon the etiology of the condition. Pelvic infection (PI) after parturition and abortion, gynecologic surgery, and a variety of invasive procedures is commonly associated with the isolation of anaerobic and aerobic flora of the vagina. The factors which influence the choice of antimicrobial treatment and the role of Bacteroides fragilis and Escherichia coli are discussed. Sexually transmissible agents of importance are Neisseria gonorrhoeae and Chlamydia trachomatis. Pelvic infections associated with these pathogens require antibiotics which exert an optimum effect against them. Examination and treatment of the sexual partner(s) are important. The possible role of the anaerobic and aerobic vaginal flora as opportunistic secondary pathogens is discussed. Developments in the surgical treatment of the sequelae of PID are reviewed. The results of treatment of uncomplicated gonorrhea in 262 women are reported. C. trachomatis was isolated from 53% of women before treatment. After treatment, PI developed in 11 women who had been given penicillin and in one woman who had been given tetracycline (P = 0.0071). It is suggested that recognition and treatment of postgonococcal cervicitis in women treated for uncomplicated gonorrhea with penicillin might provide one form of preventive treatment for nongonococcal PI.

    Mouth cancer is a major health problem. Multiple risk factors for developing mouth cancer have been studied and include history of tobacco and alcohol abuse, age over 40, exposure to ultraviolet radiation, human papilloma virus infection (HPV), nutritional deficiencies, chronic irritation, and existence or oral potentially malignant lesions such as leukoplakia and lichen planus. An important risk factor for mouth cancer is chronic immunosuppression and has been extensively reported after solid organ transplantation as well as HIV-infected patients. Diagnosis of inflammatory bowel disease (IBD) is not yet considered as a risk factor for oral cancer development. However, a significant number of patients with IBD are receiving immunosuppressants and biological therapies which could represent potential oral oncogenic factors either by direct oncogenic effect or by continuous immunosuppression favoring carcinogenesis, especially in patients with HPV(+) IBD. Education on modifiable risk behaviors in patients with IBD is the cornerstone of prevention of mouth cancer. Oral screening should be performed for all patients with IBD, especially those who are about to start an immunosuppressant or a biologic. PMID:26671147

    The incidence and prevalence of inflammatory bowel disease (IBD) is increasing globally. Coupled with an ageing population, the number of older patients with IBD is set to increase. The clinical features and therapeutic options in young and elderly patients are comparable but there are some significant differences. The wide differential diagnosis of IBD in elderly patients may result in a delay in diagnosis. The relative dearth of data specific to elderly IBD patients often resulting from their exclusion from pivotal clinical trials and the lack of consensus guidelines have made clinical decisions somewhat challenging. In addition, age specific concerns such as co-morbidity; loco-motor and cognitive function, poly-pharmacy and its consequences need to be taken into account. In applying modern treatment paradigms to the elderly, the clinician must consider the potential for more pronounced adverse effects in this vulnerable group and set appropriate boundaries maximising benefit and minimising harm. Meanwhile, clinicians need to make personalised decisions but as evidence based as possible in the holistic, considered and optimal management of IBD in elderly patients. In this review we will cover the clinical features and therapeutic options of IBD in the elderly; as well as addressing common questions and challenges posed by its management. PMID:26855812

    The etiology of pelvic inflammatory disease (PID) is speculated upon based on reported incidence and epidemiological studies. In Western society, the incidence of PID (annual) is 1% among women aged 15-34 years and 2% in the high risk group of women aged 15-24 years. The annual incidence in the US is higher, at least 2% among fecund sexually active women aged 13-44 years. The medical consequences of PID are infertility, ectopic pregnancy, and chronic pelvic pain. Causative agents include Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma hominis and various other aerobic and anaerobic microorganisms; however, the natural genital flora of females is so varied that determining actual causative agents is difficult. some case-control studies have determined risk factors for PID; these include particularly current or prior use of IUD, prior pelvic surgery, sexual activity (including number of partners), race, and prior PID acute infection. PID is not a sexually transmitted disease, but rather is classified as sexually derived. Use of barrier methods and oral contraceptives protects against PID. IUD use greatly increases the risk of PID, probably because of the avenue the device provides for organisms to ascend from the lower to the upper genital tract. The role of males in PID etiology is currently the subject of much discussion. It is theorized that the mechanical action of penis insertion in intercourse helps to move causative agents to the upper genital region; also, semen may carry vaginal flora through the cervical opening into the uterus and tubes. Menstruation and PID are closely associated, perhaps because the cervix dilates during bleedings. Research areas include: determination of role of sexual activity (and number of partners) in PID etiology; evaluation of events of menstruation that are predisposing; evaluation of relationship between bacteriosperma and lower and upper genital infections; relationship of particular contraceptive methods to PID

    The incidence of inflammatory bowel disease (IBD) is steadily in the rise in Western as well as in developing countries paralleling the increase of westernized diets, characterized by high protein and fat as well as excessive sugar intake, with less vegetables and fiber. An interesting hypothesis is that environmental (food-) triggered changes of the intestinal microbiome might cause a proinflammatory state preceding the development of IBD. Indeed, an intact intestinal epithelial barrier assuring a normal bacterial clearance of the intestinal surface is crucial to guarantee intestinal homeostasis. Any factors affecting the epithelial barrier function directly or indirectly may impact on this homeostasis, as well as any changes of the intestinal microbial composition. It is intriguing to learn that some frequently used food components impact on the quality of the intestinal barrier, as well as on the composition of the intestinal microbiome. This highlights the close interaction between living conditions, hygiene, food habits and food quality with the bacterial composition of the intestinal microbiome and the activation status of the intestinal immune system. There is clear evidence that nutritional therapy is highly successful in the treatment of Crohn's disease (CD). Exclusive enteral nutrition is well established as induction therapy of CD. New diets, such as a CD exclusion diet or defined diets (specific carbohydrate diets, FODMAP diet, Paleolithic diet) are being discussed as treatment options for IBD. Well-designed clinical trials in IBD are urgently required to define the precise role of each of these diets in the prevention or management of IBD. Up to now, the role of diet in IBD is highly undermined by lay and anecdotal reports without sufficient scientific proof. PMID:27355913

    Psoriasis is a systemic immune-inflammatory disease characterized by chronic or recurrent skin symptoms, psoriatic arthritis, enthesopathy, and uveitis. Psoriasis has recently been published to appear with various autoimmune disorders, but the coexistence has been systematically reviewed by only few studies until now. In the present study, charts and electronic database of 4344 patients with various systemic autoimmune disorders, under regular medical control at our department, were reviewed retrospectively searching for association with psoriasis. Hereby, we demonstrate 25 psoriatic patients coinciding with various systemic autoimmune diseases. The coexistence of psoriasis and autoimmune diseases resulted in the worsening of the clinical outcome of the autoimmune diseases as indicated by higher frequency and dosages of glucocorticoid use, need for biologicals, and other comorbidities. These results suggest common environmental and genetic background as well as therapeutic possibilities in the future. PMID:26339139

    We present a rare case with primary tubercular involvement of the foot, accomapanied by a reactionary (aseptic) effusion in the knee. The diagnosis was delayed due to unusual presentation and also because of failure to elicit a detailed history. Incision and drainage of the foot abscess and antitubercular drug therapy resulted in satisfactory control of tubercular infection. Polyarticular presentation may not always signify active tubercular focus in every joint; it may reflect reactive synovitis known as Poncet's disease, which resolves with multidrug antitubercular therapy.A multidispilinary approach should be adopted and chest physicians, rheumatologists and orthopaedic surgeons should work in close association to correctly diagnose and treatthis condition.

    SAPHO syndrome, representing a constellation of synovitis, acne, palmo-plantar pustulosis, hyperostosis, and osteitis, is now recognized as a distinct medical entity: a reactive infectious osteitis. Genetic, immunological, and bacterial mechanisms are implicated in the development of the disease. Diagnostic problems may arise due to non-complete manifestations of SAPHO: either acne and arthritis or acne and anterior wall osteitis with an unclear pustulosis history. The interventional study of Assmann et al. is a significant addition to a long range of publications showing an association of SAPHO with Propionibacterium acnes. Randomized control studies are needed to confirm the effects of antibiotic therapy. PMID:19895718

    Background While standard reductionist approaches have provided some insights into specific gene polymorphisms and molecular pathways involved in disease pathogenesis, our understanding of complex traits such as atherosclerosis or type 2 diabetes remains incomplete. Gene expression profiling provides an unprecedented opportunity to understand complex human diseases by providing a global view of the multiple interactions across the genome that are likely to contribute to disease pathogenesis. Thus, the goal of gene expression profiling is not to generate lists of differentially expressed genes, but to identify the physiologic or pathogenic processes and structures represented in the expression profile. Methods RNA was separately extracted from peripheral blood neutrophils and mononuclear leukocytes, labeled, and hybridized to genome level microarrays to generate expression profiles of children with polyarticular juvenile idiopathic arthritis, juvenile dermatomyositis relative to childhood controls. Statistically significantly differentially expressed genes were identified from samples of each disease relative to controls. Functional network analysis identified interactions between products of these differentially expressed genes. Results In silico models of both diseases demonstrated similar features with properties of scale-free networks previously described in physiologic systems. These networks were observable in both cells of the innate immune system (neutrophils) and cells of the adaptive immune system (peripheral blood mononuclear cells). Conclusion Genome-level transcriptional profiling from childhood onset rheumatic diseases suggested complex interactions in two arms of the immune system in both diseases. The disease associated networks showed scale-free network patterns similar to those reported in normal physiology. We postulate that these features have important implications for therapy as such networks are relatively resistant to perturbation. PMID

    Abstract Bell palsy occurs in different rheumatic diseases, causes hemifacial weakness, and targets the motor branch of the 7th cranial nerve. Severe, persistent, and refractory otalgia having features of neuropathic pain (ie, burning and allodynic) does not characteristically occur with Bell palsy. Whereas aberrant regeneration of the 7th cranial nerve occurring after a Bell palsy may lead to a variety of clinical findings, hemifacial spasm only rarely occurs. We identified in 3 rheumatic disease patients (2 with Sjögren syndrome, 1 with rheumatoid arthritis) a previously unreported neurological syndrome of facial weakness, otalgia with neuropathic pain features, and hemifacial spasm. We characterized symptoms, examination findings, and response to therapy. All 3 patients experienced vertigo, as well as severe otalgia which persisted after mild facial weakness had completely resolved within 1 to 4 weeks. The allodynic nature of otalgia was striking. Two patients were rendered homebound, as even the barest graze of outdoor breezes caused intolerable ear pain. Patients developed hemifacial spasm either at the time of or within 3 months of facial weakness. Two patients had a polyphasic course, with recurrent episodes of facial weakness and increased otalgia. In all cases, otalgia and hemifacial spasm were unresponsive to neuropathic pain regimens, but responded in 1 case to intravenous immunoglobulin therapy. No patients had vesicles or varicella zoster virus in spinal-fluid studies. We have defined a novel neurological syndrome in 3 rheumatic disease patients, characterized by facial weakness, otalgia, and hemifacial spasm. As described in infectious disorders, the combination of otalgia, facial weakness, and 8th cranial nerve deficits suggests damage to the geniculate ganglia (ie, the sensory ganglia of the 7th cranial nerve), with contiguous involvement of other cranial nerves causing facial weakness and vertigo. However, the relapsing nature and association with

    Antibodies to human native and denatured types I, II, III, IV, and V collagens were measured using 125I-radioimmunoassay. Mean levels of binding by sera from 30 rheumatoid arthritis patients were significantly higher than those from 20 normal subjects against all of the collagens tested. The relative antibody concentration was higher in synovial fluid than in simultaneously obtained serum. Many patients with gout or various other rheumatic diseases also had detectable anticollagen antibodies. With a few notable exceptions, the majority of the reactivity detected in all patient groups was directed against covalent structural determinants present on all of the denatured collagens, suggesting a secondary reaction to tissue injury.

    Inflammatory disease management poses challenges due to the complexity of inflammation and inherent patient variability, thereby necessitating patient-specific therapeutic interventions. Theranostics, which integrate therapeutic and imaging functionalities, can be used for simultaneous imaging and treatment of inflammatory diseases. Theranostics could facilitate assessment of safety, toxicity and real-time therapeutic efficacy leading to personalized treatment strategies. Macrophages are an important cellular component of inflammatory diseases, participating in varied roles of disease exacerbation and resolution. The inherent phagocytic nature, abundance and disease homing properties of macrophages can be targeted for imaging and therapeutic purposes. This review discusses the utility of theranostics in macrophage ablation, phenotype modulation and inhibition of their inflammatory activity leading to resolution of inflammation in several diseases.

    Thymosin alpha 1 (Tα1) is a powerful modulator of immunity and inflammation. Despite years of studies, there are a few reports evaluating serum Tα1 in health and disease. We studied a cohort of healthy individuals in comparison with patients affected by chronic inflammatory autoimmune diseases. Sera from 120 blood donors (healthy controls, HC), 120 patients with psoriatic arthritis (PsA), 40 with rheumatoid arthritis (RA) and 40 with systemic lupus erythematosus (SLE), attending the Transfusion Medicine or the Rheumatology Clinic at the Policlinico Tor Vergata, Rome, Italy, were tested for Tα1 content by means of a commercial enzyme-linked immunosorbent assay (ELISA) kit. Data were analysed in relation to demographic and clinical characteristics of patients and controls. A gender difference was found in the HC group, where females had lower serum Tα1 levels than males (P < 0·0001). Patients had lower serum Tα1 levels than HC (P < 0·0001), the lowest were observed in PsA group (P < 0·0001 versus all the other groups). Among all patients, those who at the time of blood collection were taking disease-modifying anti-rheumatic drugs (DMARD) plus steroids had significantly higher Tα1 levels than those taking DMARD alone (P = 0·044) or no treatment (P < 0·0001), but not of those taking steroids alone (P = 0·280). However, whichever type of treatment was taken by the patients, serum Tα1 was still significantly lower than in HC and there was no treatment-related difference in PsA group. Further prospective studies are necessary to confirm and deepen these observations. They might improve our understanding on the regulatory role of Tα1 in health and disease and increase our knowledge of the pathogenesis of chronic inflammatory autoimmune diseases. PMID:27350088
