  3. TNFα blockers and infectious risk in rheumatoid arthritis

    Directory of Open Access Journals (Sweden)

    2011-06-01

    Full Text Available Patients suffering from rheumatoid arthritis have increased risk of infections when compared with general population. The risk depends directly from disease activity and severity. Furthermore, risk increases with aging, immunosuppressive agents and comorbidities such as diabetes, pulmonary and cardiac diseases. In particular corticosteroids, even at low doses, are a major risk factor. Due to disease related risk it is difficult to separate the risk deriving from the use of TNF alpha blockers. Data from clinical trials, meta-analysis and national registers are somewhat contradictory. In patients with rheumatoid arthritis on routine follow-up, treatment with TNF alpha blockers seems to carry an increased risk of infections compared to traditional DMARDs but not associated with increased risk of overall serious infection. Physicians should carefully monitor for signs of infection when using TNF alpha blockers, particularly shortly after treatment initiation.

    An association between oral disease/periodontitis and rheumatoid arthritis (RA) has been considered since the early 1820s. The early treatment was tooth eradication. Epidemiological studies suggest that the prevalence of RA and periodontitis may be similar and about 5% of the population are aged 50 years or older. RA is considered as an autoimmune disease whereas periodontitis has an infectious etiology with a complex inflammatory response. Both diseases are chronic and may present with burst...

    Full Text Available Abstract Background Reactive arthritis (ReA is a recognized sequela of infectious gastroenteritis (IGE. However, the population-based incidence of IGE-related ReA is poorly defined, and the risk of disease has not previously been characterized in a military population. The intent of this study was to provide estimates of the incidence and morbidity associated with IGE-related ReA in the U.S. military population. Methods Using active duty US military medical encounter data from the Defense Medical Surveillance System, we conducted a matched case-control study to assess the risk of ReA following IGE. Both specific and nonspecific case definitions were utilized to address ICD-9 coding limitations; these included specific ReA (Reiter's Disease or postdysenteric arthritis and nonspecific arthritis/arthralgia (N.A.A (which included several related arthropathy and arthralgia diagnoses. Incidence was estimated using events and the total number of active duty personnel for each year. Results 506 cases of specific ReA were identified in active duty personnel between 1999 and 2007. Another 16,365 cases of N.A.A. were identified. Overall incidence was 4.1 (95% CI: 3.7, 4.5 and 132.0 (95% CI, 130.0-134.0 per 100,000 for specific ReA and N.A.A, respectively. Compared to the youngest age category, the incidence of both outcomes increased 7-fold with a concurrent increase in symptom duration for cases over the age of 40. Specific IGE exposures were documented in 1.4% of subjects. After adjusting for potential confounders, there was a significant association between IGE and ReA (specific reactive arthritis OR: 4.42, 95% CI: 2.24, 8.73; N.A.A OR: 1.76, 95% CI: 1.49, 2.07. Conclusions Reactive arthritis may be more common in military populations than previously described. The burden of ReA and strong association with antecedent IGE warrants continued IGE prevention efforts.

    Full Text Available Reactive arthritis is an acute, sterile, non-suppurative and inflammatory arthropaty which has occured as a result of an infectious processes, mostly after gastrointestinal and genitourinary tract infections. Reiter syndrome is a frequent type of reactive arthritis. Both reactive arthritis and Reiter syndrome belong to the group of seronegative spondyloarthropathies, associated with HLA-B27 positivity and characterized by ongoing inflammation after an infectious episode. The classical triad of Reiter syndrome is defined as arthritis, conjuctivitis and urethritis and is seen only in one third of patients with Reiter syndrome. Recently, seronegative asymmetric arthritis and typical extraarticular involvement are thought to be adequate for the diagnosis. However, there is no established criteria for the diagnosis of reactive arthritis and the number of randomized and controlled studies about the therapy is not enough.

    Background Sex medicine studies have shown that there are sex differences with regard to disease characteristics in immune-mediated inflammatory diseases, including psoriasis, in immune response and susceptibility to viral infections. We performed a post hoc analysis of the Observational Study of infectious events in psoriasis complicated by active psoriatic arthritis (SYNERGY) study in patients with psoriatic arthritis (PsA) treated with immunosuppressive regimens including cyclosporine, in order to evaluate potential between-sex differences in severity of disease and prevalence of viral infections. Methods SYNERGY was an observational study conducted in 24 Italian dermatology clinics, which included 238 consecutively enrolled patients with PsA, under treatment with immunosuppressant regimens including cyclosporin A. In this post hoc analysis, patients’ demographical data and clinical characteristics of psoriasis, severity and activity of PsA, prevalence of seropositivity for at least one viral infection, and treatments administered for PsA and infections were compared between sexes. Results A total of 225 patients were evaluated in this post hoc analysis, and 121 (54%) were males. Demographic characteristics and concomitant diseases were comparable between sexes. Statistically significant sex differences were observed at baseline in Psoriasis Area and Severity Index score (higher in males), mean number of painful joints, Bath Ankylosing Spondylitis Disease Activity Index, and the global activity of disease assessed by patients (all higher in females). The percentage of patients with at least one seropositivity detected at baseline, indicative of concomitant or former viral infection, was significantly higher among women than among men. No between-sex differences were detected in other measures, at other time points, and in treatments. Patients developed no hepatitis B virus or hepatitis C virus reactivation during cyclosporine treatment. Conclusion Our post hoc

    Aortitis is broadly divided into infectious and non-infectious etiologies, each with distinct treatment implications. We present the case of a patient who sustained a type A aortic dissection during urgent coronary angiography for acute coronary syndrome. Clinical findings and events during the procedure raised suspicion for an underlying vascular disorder; however, the diagnosis of staphylococcal aortitis was not made until pathological examination of resected tissue. Clues to the diagnosis of infectious aortitis noted throughout the patient's clinical course are detailed as are potential consequences of diagnostic delays and treatment decisions, underscoring the difficulties in recognizing and managing the condition. In addition, we describe a previously unreported complication of cardiac catheterization in the setting of an infectious aortopathy.

    Acute-onset arthritis is a common clinical problem facing both the general clinician and the rheumatologist. A viral aetiology is though to be responsible for approximately 1% of all cases of acute arthritis with a wide range of causal agents recognised. The epidemiology of acute viral arthritis continues to evolve, with some aetiologies, such as rubella, becoming less common due to vaccination, while some vector-borne viruses have become more widespread. A travel history therefore forms an important part of the assessment of patients presenting with an acute arthritis. Worldwide, parvovirus B19, hepatitis B and C, HIV and the alphaviruses are among the most important causes of virally mediated arthritis. Targeted serological testing may be of value in establishing a diagnosis, and clinicians must also be aware that low-titre autoantibodies, such as rheumatoid factor and antinuclear antibody, can occur in the context of acute viral arthritis. A careful consideration of epidemiological, clinical and serological features is therefore required to guide clinicians in making diagnostic and treatment decisions. While most virally mediated arthritides are self-limiting some warrant the initiation of specific antiviral therapy. PMID:27037381

    The purpose of this review is to describe the spectrum of sonographic findings in rheumatic diseases with respect to the diagnostic potential using US contrast media which prove activity or inactivity in synovial tissue where new treatment regimes target. Synovial activity can be found in non-erosive and erosive forms of primary and secondary osteoarthritis, and in inflammatory forms of joint diseases like rheumatoid arthritis and peripheral manifestations of spondyloarthritis including, ankylosing spondylitis, Reiter's syndrome, psoriatic arthritis and enteropathic arthritis. It can also be present in metabolic and endocrine forms of arthritis, in connective tissue arthropathies like systemic lupus erythematosus or scleroderma and in infectious arthritis. Ultrasound should be used as first-line imaging modality in suspected early cases of RA and other forms of arthritis, whereas contrast-enhanced ultrasound (CEUS) can further enable for sensitive assessment of vascularity which correlates with disease activity.

    Septic arthritis of the temporomandibular joint (TMJ) is an uncommon condition, caused by hematic bacterial migration or direct migration of other head and neck infections. We report a 41 year old female who presented a right temporomandibular joint involvement, with bone destruction of the mandibular condyle and an infectious process spreading to the temporal space, following a necrotizing medial and external otitis with associated mastoiditis. A septic arthritis of the TMJ by continuity was diagnosed and treated with antimicrobials, TMJ arthrocentesis and occlusal stabilization, with a positive evolution. However, the patient remains in control due a secondary TMJ osteoarthritis caused by the septic arthritis.

Ten rabbit knees with septic arthritis and four with talc synovitis were imaged with MR. Contralateral knees injected with saline served as controls. Fat saturation T2-weighted and gadolinium-enhanced T1-weighted images were assessed for joint effusion, and periarticular and adjacent intraosseous increased signal or enhancement. Each knee was cultured and underwent pathologic examination. Results. Both Staphylococcus aureus and talc produced effusions in all knees. The degree of periarticular signal and enhancement was greater in infected knees than talc-injected knees. No abnormal enhancement was seen within bone. Pathologic examination showed a greater degree of inflammation and joint destruction in the infected knees, but no evidence of osteomyelitis. Conclusion. A greater degree of abnormal signal and enhancement seen on MR suggests a more vigorous inflammatory process, as seen with septic arthritis. In spite of advanced septic arthritis, no enhancement was evident within bone, suggesting that enhancement within bone is not an expected finding in isolated septic arthritis and should raise concern for osteomyelitis.

    The development of novel anti-rheumatic drugs revolutionizes currently therapeutic strategies and diagnostic management of patients with rheumatoid arthritis, facilitating the goal of true remission instead of only symptomatic treatment as in former years. Since early treatment is known to be crucial for the longterm outcome, imaging modalities such as magnetic resonance imaging and high-frequency ultrasonography including Doppler sonography, which allow direct visualization of very early pathologic alterations of synovitis, or even initial destruction, become increasingly important. Besides the established therapy with methotrexate, new drugs such as leflunomide or the use of various combination therapies have been successfully introduced into the therapeutic armamentarium. Especially the introduction of cytokine-antagonists such as TNF-a inhibitors target the aim of remission. In addition, the upcoming therapeutic agents, which influence very effectively the inflammatory and destructive process need also to be integrated into the concert of different therapeutic strategies in the management of patients with rheumatoid arthritis, which includes the mandatory complementary factors such as physiotherapy, ergotherapy and orthopedic surgery.

    Osteoarthritis of knee is one of the common problems in elderly population. Intraarticular corticosteroid injection is a conservative management modality in osteoarthritis of knee. Septic arthritis is an infective complication of intraarticular corticosteroid injection. Septic arthritis in rheumatoid arthritis patients have worse prognosis because of delay in diagnosis. A higher rate of infectious complications following intraarticular injection is expected in immunocompromised and rheumatoid patients. We would like to report an extremely rare case of simultaneous bilateral knee septic arthritis after bilateral knee intraarticular steroid injection in a rheumatoid arthritis patient. Patient was treated successfully with multiple bilateral knee arthroscopic washouts and long-term intravenous antibiotics. This case report emphasizes the increased risk of infection in rheumatoid arthritis patients and a risk benefit assessment on individual basis before carrying out intraarticular steroid injection. Patient should be aware of this increased risk of infection.

  11. Reactive arthritis: advances in diagnosis and treatment

    Directory of Open Access Journals (Sweden)

    2011-09-01

    Full Text Available Reactive Arthritis (ReA is an aseptic synovitis developing after a primary infection distant from the joint, mainly localized in the gastrointestinal (Enteroarthritis or genitourinary tract (Uroarthritis. Because of either the asymmetric joint involvement, the possibility of involvement of the spine and enthesis, and the HLA-B27 association ReA is considered one of the spondylarthropathies. Recently, bacterial components or viable bacteria were found in joints during ReA. For this reason, the limits between ReA itself and infectious arthritis are now less definite. Generally accepted diagnostic and classification criteria are still lacking but the improvement in techniques for detection of bacteria increase the possibility to identify the triggering agents. Several studies have examined the role of antimicrobial drugs in ameliorating the natural course of ReA, with some positive results for Uroarthritis only. However, more conventional treatments based on NSAIDs, Sulfasalazine and steroids are effective in many cases.

    Biological agents are widely used for various immune-mediated diseases, with remarkable effectiveness in the treatment of rheumatoid arthritis (RA), psoriasis, psoriatic arthritis, ankylosing spondylitis and Crohn's disease. However, attention needs to be drawn to the adverse effects of these therapies and the risk of reactivating underlying granulomatous infectious diseases such as tuberculosis, leprosy, syphilis, leishmaniasis, among others. The objective of this paper is to describe a case of leprosy in a patient with RA using anti-TNF alfa, demonstrating the need for systematic investigation of skin lesions suggestive of leprosy in patients who require rheumatoid arthritis therapeutic treatment, especially in endemic regions like Brazil.

  1. Surgical options for the young patient with glenohumeral arthritis.

    Science.gov (United States)

    Barlow, Jonathan D; Abboud, Joseph

    2016-01-01

    Young patients with glenohumeral arthritis are an ongoing treatment challenge. They typically have high demands of their shoulders, require long-term durability due to their young age, and often have altered local anatomy, through their disease process (instability arthropathy, juvenile rheumatoid arthritis, etc.) or from previous surgery (capsulorraphy arthropathy, chondrolysis, etc.). Workup to evaluate underlying causes of early arthritis, and to exclude infectious causes are necessary. When nonoperative management fails, arthroscopic debridement, hemiarthroplasty (isolated, with glenoid reaming, or with biological interposition), and total shoulder arthroplasty are treatment options available to the treating surgeon. Debridement or hemiarthroplasty can provide pain relief for a subset of patients, but results have not been reproducible across the literature and have not been durable over time. Total shoulder arthroplasty provides the most reliable pain relief, but long-term glenoid loosening and wear continue to lead to high revision rates in this patient population. PMID:26980987

    Septic arthritis and spondylitis in elderly adult are uncommon disease. But symptoms and signs of septic arthritis and spondylitis are an important medical emergency, with high mortality and morbidity. Delayed or inadequate treatment can result in irreversible joint destruction and neurological condition. Early diagnoses as well as prompt and effective treatment are essential for avoiding severe outcomes. In spite of advances in diagnostic imaging techniques, the incidence of septic arthritis and spondylitis appears to have been increased. The aging of the population, the widespread use of immunosuppressant therapies, including systemic corticosteroids, cytokines and anticytokines, and growing resistance to conventional antibiotics seem to be the major cause.

  5. Fight against infectious diseases.

    Soda, K; Kamakura, M; Kitamura, K

    1996-08-01

    During early Meiji era in Japan, there were frequent epidemics of fatal acute communicable diseases such as cholera, dysentery and smallpox, and preventive measures and preparations for acute infectious diseases were urgently needed. Together with improvement of scientific preparations, the Communicable Disease Prevention Law was promulgated in 1897. Then gradually until 1940's, the focus of preventive measures have been shifted from acute infectious diseases to chronic ones, particularly tuberculosis. After the World War II, except the short period of social confusion, major legally-defined communicable diseases had been decreasing rapidly mainly due to the use of antibiotics and improvement of environmental sanitation. At the same time, the introduction of preventive vaccination marked a new era for the prevention of infectious diseases and was largely responsible for the remarkable decrease of infant mortality in Japan. Recently the concept of defense by vaccination against infectious diseases has evolved from group-oriented to individual-oriented, so that the Preventive Vaccination Law was drastically revised in 1994. Currently, effective counter-measures against newly emerged infectious diseases, as viral hepatitis, institution-acquired infection, viral hemorrhagic fever etc., have been implemented. For the future, improvement of infections disease surveillance, vaccine development and expansion of vaccination coverage along with monitoring side-effects, preventive health education on AIDS/STDs, addressing the special needs of foreigners living in Japan and international collaboration for disease control abroad are all vital to the success of protection of the public's health from infectious diseases in Japan.

    Directory of Open Access Journals (Sweden)

    Khairallah Moncef

    2009-01-01

    Full Text Available Infectious causes should always be considered in all patients with uveitis and it should be ruled out first. The differential diagnosis includes multiple well-known diseases including herpes, syphilis, toxoplasmosis, tuberculosis, bartonellosis, Lyme disease, and others. However, clinicians should be aware of emerging infectious agents as potential causes of systemic illness and also intraocular inflammation. Air travel, immigration, and globalization of business have overturned traditional pattern of geographic distribution of infectious diseases, and therefore one should work locally but think globally, though it is not possible always. This review recapitulates the systemic and ocular mainfestations of several emergent infectious diseases relevant to the ophthalmologist including Rickettsioses, West Nile virus infection, Rift valley fever, dengue fever, and chikungunya. Retinitis, chorioretinitis, retinal vasculitis, and optic nerve involvement have been associated with these emergent infectious diseases. The diagnosis of any of these infections is usually based on pattern of uveitis, systemic symptoms and signs, and specific epidemiological data and confirmed by detection of specific antibody in serum. A systematic ocular examination, showing fairly typical fundus findings, may help in establishing an early clinical diagnosis, which allows prompt, appropriate management.

  15. A case of reactive arthritis due to Clostridium difficile colitis

    Science.gov (United States)

    Essenmacher, Alex C.; Khurram, Nazish; Bismack, Gregory T.

    2016-01-01

    Reactive arthritis is an acute, aseptic, inflammatory arthropathy following an infectious process but removed from the site of primary infection. It is often attributed to genitourinary and enteric pathogens, such as Chlamydia, Salmonella, Shigella, Campylobacter, and Yersinia, in susceptible individuals. An uncommon and less recognized cause of this disease is preceding colonic infection with Clostridium difficile, an organism associated with pseudomembranous colitis and diarrhea in hospitalized patients and those recently exposed to antibiotics. Recognition of this association may be complicated by non-specific presentation of diarrhea, the interval between gastrointestinal and arthritic symptoms, and the wide differential in mono- and oligoarthritis. We present the case of a 61-year-old, hospitalized patient recently treated for C. difficile colitis who developed sudden, non-traumatic, right knee pain and swelling. Physical examination and radiographs disclosed joint effusion, and sterile aspiration produced cloudy fluid with predominant neutrophils and no growth on cultures. Diagnostic accuracy is enhanced by contemporaneous laboratory investigations excluding other entities such as gout and rheumatoid arthritis and other infections that typically precede reactive arthritis. Contribution of Clostridium infection to reactive arthritis is an obscure association frequently difficult to prove, but this organism is warranted inclusion in the differential of reactive arthritis.

    2015-12-01

    Dynamic models of infectious disease systems abound and are used to study the epidemiological characteristics of disease outbreaks, the ecological mechanisms affecting transmission, and the suitability of various control and intervention strategies. The dynamics of disease transmission are non-linear and consequently difficult to forecast. Here, we describe combined model-inference frameworks developed for the prediction of infectious diseases. We show that accurate and reliable predictions of seasonal influenza outbreaks can be made using a mathematical model representing population-level influenza transmission dynamics that has been recursively optimized using ensemble data assimilation techniques and real-time estimates of influenza incidence. Operational real-time forecasts of influenza and other infectious diseases have been and are currently being generated.

    Science.gov (United States)

    Stanich, Jessica A; Carter, John D; Whittum-Hudson, Judith; Hudson, Alan P

    2009-01-01

    Rheumatoid arthritis (RA) has been described in the medical literature for over two hundred years, but its etiology remains unknown. RA displays phenotypic heterogeneity, and it is a relatively prevalent clinical entity: it affects approximately 1% of the population, resulting in enormous pathologic sequelae. Earlier studies targeting the cause(s) of RA suggested potential infectious involvement, whereas more recent reports have focused on a genetic origin of the disease. However, neither infection nor genetics, nor any other single factor is currently accepted as causative of RA. In this article we review studies relating to the etiology of RA, and those of several related matters, and we conclude that the literature indeed does provide insight into the causes underlying the initiation of RA pathogenesis. Briefly, given the remarkable phenotypic variation of RA, especially in its early stages, as well as a number of other characteristics of the condition, we contend that RA is not a discrete clinical entity with a single etiological source. Rather, we argue that it represents a common clinical endpoint for various starting points, each of which is largely guided by as yet poorly understood aspects of the genetic background of the affected individual. Adoption of this alternative view of the origin of RA will have significant consequences for future research and for development of new therapeutic interventions for this burdensome condition.

    2014-02-01

    Modern infectious disease epidemiology has a strong history of using mathematics both for prediction and to gain a deeper understanding. However the study of infectious diseases is a highly interdisciplinary subject requiring insights from multiple disciplines, in particular a biological knowledge of the pathogen, a statistical description of the available data and a mathematical framework for prediction. Here we begin with the basic building blocks of infectious disease epidemiology—the SIS and SIR type models—before considering the progress that has been made over the recent decades and the challenges that lie ahead. Throughout we focus on the understanding that can be developed from relatively simple models, although accurate prediction will inevitably require far greater complexity beyond the scope of this review. In particular, we focus on three critical aspects of infectious disease models that we feel fundamentally shape their dynamics: heterogeneously structured populations, stochasticity and spatial structure. Throughout we relate the mathematical models and their results to a variety of real-world problems.

    Whether the levels of procalcitonin (PCT) in the serum and synovial fluid are effective indicators for distinguishing septic arthritis (SA) from non-infectious arthritis remains controversial. The present study aimed to evaluate whether PCT levels in fresh serum or fresh joint fluid may be used in the differential diagnosis of SA from rheumatoid arthritis (RA), osteoarthritis (OA) and gouty arthritis (GA). From January 2012 to June 2013, 23 patients with knee SA, 21 patients with RA, 40 patients with OA and 11 patients with GA were enrolled in the current study. The levels of PCT were measured within 24 h after specimen collection at room temperature. An enzyme-linked fluorescence assay (ELFA) was used to detect the levels of PCT in the serum and synovial fluid. The correlations between the levels of PCT in the serum and synovial fluid and the arthritic patient groups were determined by the Nemenyi test. Areas under the receiver operating characteristic (ROC) curve were calculated to evaluate the accuracy of the correlations. The levels of PCT in the serum and joint fluid of the patients in the SA group were higher compared with those of the other groups (Parthritis; however, the PCT levels in fresh synovial fluid are more sensitive and accurate indicators than PCT levels in fresh serum.

    2015-11-01

    The introduction of new biological drugs for the treatment of rheumatoid arthritis and spondyloarthritis has led to the creation of a number of registries in Europe and the United States. Most of them are sponsored by national rheumatology societies, and provide information that is useful in clinical practice concerning the clinical characteristics, efficacy, and safety of all licensed biological drugs. Their findings also help to improve our understanding of the quality of life and working ability of patients receiving biological drugs, and suggest methods for allocating resources. However, there are only a few registries for psoriatic arthritis, and efforts should be made to increase their number to obtain further reliable and useful data.

  14. Global emergence of Alphaviruses that cause arthritis in humans

    Directory of Open Access Journals (Sweden)

    Olivia Wesula Lwande

    2015-12-01

    Full Text Available Arthropod-borne viruses (arboviruses may cause severe emerging and re-emerging infectious diseases, which pose a significant threat to human and animal health in the world today. These infectious diseases range from mild febrile illnesses, arthritis, and encephalitis to haemorrhagic fevers. It is postulated that certain environmental factors, vector competence, and host susceptibility have a major impact on the ecology of arboviral diseases. Presently, there is a great interest in the emergence of Alphaviruses because these viruses, including Chikungunya virus, O'nyong'nyong virus, Sindbis virus, Ross River virus, and Mayaro virus, have caused outbreaks in Africa, Asia, Australia, Europe, and America. Some of these viruses are more common in the tropics, whereas others are also found in temperate regions, but the actual factors driving Alphavirus emergence and re-emergence remain unresolved. Furthermore, little is known about the transmission dynamics, pathophysiology, genetic diversity, and evolution of circulating viral strains. In addition, the clinical presentation of Alphaviruses may be similar to other diseases such as dengue, malaria, and typhoid, hence leading to misdiagnosis. However, the typical presence of arthritis may distinguish between Alphaviruses and other differential diagnoses. The absence of validated diagnostic kits for Alphaviruses makes even routine surveillance less feasible. For that purpose, this review describes the occurrence, genetic diversity, clinical characteristics, and the mechanisms involving Alphaviruses causing arthritis in humans. This information may serve as a basis for better awareness and detection of Alphavirus-caused diseases during outbreaks and in establishing appropriate prevention and control measures.

  15. Avian infectious laryngotracheitis.

    2000-08-01

    Avian infectious laryngotracheitis (ILT) herpesvirus continues to cause sporadic cases of respiratory disease in chickens world-wide. Sources of transmission of ILT infection are three-fold, namely: chickens with acute upper respiratory tract disease, latently infected 'carrier' fowls which excrete infectious laryngotracheitis virus (ILTV) when stressed, and all fomites (inanimate articles as well as the personnel in contact with infected chickens). Infectious laryngotracheitis virus infectivity can persist for weeks to months in tracheal mucus or carcasses. Rigorous site biosecurity is therefore critical in ILT disease control. Furthermore, while current (modified live) ILT vaccines can offer good protection, the strains of ILTV used in vaccines can also produce latent infections, as well as ILT disease following bird-to-bird spread. The regional nature of reservoirs of ILTV-infected flocks will tend to interact unfavourably with widely varying ILT control practices in the poultry industry, so as to periodically result in sporadic and unexpected outbreaks of ILT in intensive poultry industry populations. Precautions for trade-related movements of chickens of all ages must therefore include an accurate knowledge of the ILT infection status, both of the donor and recipient flocks. PMID:10935275

    Kanski, J J

    1990-01-01

    The association between juvenile arthritis and uveitis is reviewed. Some children with the HLA-B27 related spondyloarthropathies develop anterior uveitis. About 20% of patients with juvenile rheumatoid arthritis (JRA) who are negative for IgM rheumatoid factor develop a frequently bilateral, nongranulomatous chronic anterior uveitis. Risk factors for uveitis in JRA patients are: female gender, pauciarticular onset of arthritis, presence of circulating antinuclear antibodies, and the antigens HLA-DW5 and HLA-DPw2. Uveitis is rare after seven years or more have elapsed from the onset of arthritis. The visual prognosis in patients with uveitis is good in 25% and fair in 50%. The remaining 25% develop visual impairment from complicated cataract and/or secondary inflammatory glaucoma. The potential benefit of cytotoxic agents in the treatment of intractable uveitis is outweighed by the risk of serious side effects. The management of secondary inflammatory glaucoma is unsatisfactory, but the results of treatment of complicated cataracts by lensectomy-vitrectomy are good.

    2009-10-01

    Feline infectious peritonitis (FIP) frequently results in death in cats. It is caused by a mutated, highly contagious coronavirus, and it is more common in indoor cats in multicat households. A complex interaction between the coronavirus and the feline immune system causes disseminated vasculitis, which is the hallmark of FIP. New tests are being developed, but the antemortem diagnosis of FIP continues to be difficult and frustrating. Current treatments are crude and involve supportive care and immunosuppression. Minimizing exposure is the best method of preventing infection.

    This article discusses the nature of the health challenges created by globalization and proposes new forms of international cooperation to confront them. The discussion of global health challenges includes both the transfer of health risks, with an emphasis on infectious diseases, and the international dissemination of health opportunities, including the transfer of knowledge and technology. The authors argue that the health-related challenges and opportunities of an increasingly interdependent world demand new forms of international cooperation. The authors suggest the promotion of 3 elements that, in their essence, contain the idea of collaboration: exchange, evidence, and empathy.

    The maintenance of transplantation tolerance induced in adult mice after short-term treatment with nonlytic monoclonal antibodies to CD4 and CD8 was investigated. CD4^+ T cells from tolerant mice disabled naive lymphocytes so that they too could not reject the graft. The naive lymphocytes that had been so disabled also became tolerant and, in turn, developed the capacity to specifically disable other naive lymphocytes. This process of "infectious" tolerance explains why no further immunosuppression was needed to maintain long-term transplantation tolerance.

  8. Mitigating Infectious Disease Outbreaks

    Science.gov (United States)

    Davey, Victoria

    The emergence of new, transmissible infections poses a significant threat to human populations. As the 2009 novel influenza A/H1N1 pandemic and the 2014-2015 Ebola epidemic demonstrate, we have observed the effects of rapid spread of illness in non-immune populations and experienced disturbing uncertainty about future potential for human suffering and societal disruption. Clinical and epidemiologic characteristics of a newly emerged infectious organism are usually gathered in retrospect as the outbreak evolves and affects populations. Knowledge of potential effects of outbreaks and epidemics and most importantly, mitigation at community, regional, national and global levels is needed to inform policy that will prepare and protect people. Study of possible outcomes of evolving epidemics and application of mitigation strategies is not possible in observational or experimental research designs, but computational modeling allows conduct of `virtual' experiments. Results of well-designed computer simulations can aid in the selection and implementation of strategies that limit illness and death, and maintain systems of healthcare and other critical resources that are vital to public protection.

    Viral studies were carried out on throat swabs, rectal swabs and washed white blood cells from 27 cases of infectious mononucleosis (positive Paul-Bunnell-David-sohn test), and from 22 controls. Four cytopathic agents were isolated in the test group, two of which were readily subcultured for at least three successive passages. Three cytopathic agents were recovered in the control group, two of which have been identified as adenovirus type 5 and adenovirus type 3. The unidentified agents tested so far are sensitive to ether and to pH 3. The results of acridine-orange staining and the immunofluorescence technique, using a conjugated control serum and two conjugated convalescent infectious mononucleosis sera, indicate that the isolated agent or agents in the test group are RNA-type agents with a cytoplasmic cycle of development. The overall results of this study lead the authors to suspect a respiratory syncytial-like myxovirus as the as yet unidentified agent which they recovered.

  11. [Treatment Strategies for Septic Arthritis of the Sternoclavicular Joint].

    Science.gov (United States)

    Kuhtin, O; Schmidt-Rohlfing, B; Dittrich, M; Lampl, L; Hohls, M; Haas, V

    2015-10-01

    Septic arthritis of the sternoclavicular joint (SCJ) is a relatively rare disease. Due to serious complications including mediastinitis and generalised sepsis early diagnosis and rapid onset of treatment are mandatory. The disease often affects immunocompromised patients, diabetics, or patients with other infectious diseases. The therapeutic options range from administration of antibiotics to extended surgery including reconstructive procedures. Apart from rare situations where conservative treatment with antibiotics is sufficient, joint resection followed by plastic surgical procedures are required. We present a retrospective analysis with data from two hospitals. From January 2008 to December 2012 23 patients with radiographically confirmed septic arthritis of various aetiology were included. Fourteen (60.8 %) male, nine (39.2 %) female patients with an average age of 60.3 ± 14.2 years (range: 23-88 years) with septic arthritis of the SCJ were treated. Seven (30.4 %) patients suffered from Diabetes mellitus, nine (39.1 %) had underlying diseases with a compromised immune system. In 14 (60.8 %) out of 23 patients a bacterial focus was detected. Only six (26 %) patients suffered from confined septic arthritis of the SCG, in 17 (73,9 %) patients osteomyelitis of the adjacent sternum, and the clavicle was present. In addition, 15 (65.2 %) patients already suffered from mediastinitis at the time of diagnosis, eight (35 %) patients even from septicaemia. In conclusion, septic arthritis requires an active surgical treatment. Limited incision of the joint and debridement alone is only successful at early stages of the disease. The treatment concept has to include the local joint and bone resection as well as complications like mediastinitis. After successful treatment of the infection, the defect of the chest wall requires secondary reconstructive surgery using a pedicled pectoralis muscle flap.

    Minooee, Arezou; Wang, Jeff; Gupta, Geeta K

    2015-10-01

    Although the medical complications of sports are usually traumatic in nature, infectious hazards also arise. While blood-borne pathogens such as HIV, hepatitis B, and hepatitis C, cause significant illness, the risk of acquiring these agents during sporting activities is minimal. Skin infections are more commonplace, arising from a variety of microbial agents including bacterial, fungal, and viral pathogens. Sports involving water contact can lead to enteric infections, eye infections, or disseminated infections such as leptospirosis. Mumps, measles, and influenza are vaccine-preventable diseases that have been transmitted during sporting events, both in players and in spectators. Prevention is the key to many of these infections. Players should be vaccinated and should not participate in sports if their infection can be spread by contact, airborne, or droplet transmission.

  14. Wetlands and infectious diseases

    2001-01-01

    Full Text Available There is a historical association between wetlands and infectious disease that has led to the modification of wetlands to prevent disease. At the same time there has been the development of water resources projects that increase the risk of disease. The demand for more water development projects and the increased pressure to make natural wetlands economically beneficial creates the need for an ecological approach to wetland management and health assessment. The environmental and health interactions are many. There is a need to take into account the landscape, spatial boundaries, and cross-boundary interactions in water development projects as well as alternative methods to provide water for human needs. The research challenges that need to be addressed are discussed.

    2015-09-01

    Rheumatoid arthritis (RA) is a chronic debilitating autoimmune disorder characterized by synovitis that leads to cartilage and bone erosion by invading fibrovascular tissue. Mouse models of RA recapitulate many features of the human disease. Despite the availability of medicines that are highly effective in many patient populations, autoimmune diseases (including RA) remain an area of active biomedical research, and consequently mouse models of RA are still extensively used for mechanistic studies and validation of therapeutic targets. This review aims to integrate morphologic features with model biology and cover the key characteristics of the most commonly used induced and spontaneous mouse models of RA. Induced models emphasized in this review include collagen-induced arthritis and antibody-induced arthritis. Collagen-induced arthritis is an example of an active immunization strategy, whereas antibody- induced arthritis models, such as collagen antibody-induced arthritis and K/BxN antibody transfer arthritis, represent examples of passive immunization strategies. The coverage of spontaneous models in this review is focused on the TNFΔ (ARE) mouse, in which arthritis results from overexpression of TNF-α, a master proinflammatory cytokine that drives disease in many patients.

    Rheumatoid arthritis (RA) is a chronic debilitating autoimmune disorder characterized by synovitis that leads to cartilage and bone erosion by invading fibrovascular tissue. Mouse models of RA recapitulate many features of the human disease. Despite the availability of medicines that are highly effective in many patient populations, autoimmune diseases (including RA) remain an area of active biomedical research, and consequently mouse models of RA are still extensively used for mechanistic studies and validation of therapeutic targets. This review aims to integrate morphologic features with model biology and cover the key characteristics of the most commonly used induced and spontaneous mouse models of RA. Induced models emphasized in this review include collagen-induced arthritis and antibody-induced arthritis. Collagen-induced arthritis is an example of an active immunization strategy, whereas antibody- induced arthritis models, such as collagen antibody-induced arthritis and K/BxN antibody transfer arthritis, represent examples of passive immunization strategies. The coverage of spontaneous models in this review is focused on the TNFΔ (ARE) mouse, in which arthritis results from overexpression of TNF-α, a master proinflammatory cytokine that drives disease in many patients.

    Rheumatoid arthritis (RA) is a systemic chronic inflammatory disease characterized by extensive synovitis resulting in erosions of articular cartilage and marginal bone with joint destruction. The lack of immunological tolerance in RA represents the first step toward the development of autoimmunity. Susceptible individuals, under the influence of environmental factors, such as tobacco smoke, and silica exposure, develop autoimmune phenomena that result in the presence of autoantibodies. HLA and non-HLA haplotypes play a major role in determining the development of specific autoantibodies differentiating anti-citrullinated antibodies (ACPA)-positive and negative RA patients. Rheumatoid factor (RF) and ACPA are the serological markers for RA, and during the preclinical immunological phase, autoantibody titers increase with a progressive spread of ACPA antigens repertoire. The presence of ACPA represents an independent risk factor for developing RA in patients with undifferentiated arthritis or arthralgia. Moreover, anti-CarP antibodies have been identified in patients with RA as well as in individuals before the onset of clinical symptoms of RA. Several autoantibodies mainly targeting post-translational modified proteins have been investigated as possible biomarkers to improve the early diagnosis, prognosis and response to therapy in RA patients. Psoriatic arthritis (PsA) is distinguished from RA by infrequent positivity for RF and ACPA, together with other distinctive clinical features. Actually, specific autoantibodies have not been described. Recently, anti-CarP antibodies have been reported in sera from PsA patients with active disease. Further investigations on autoantibodies showing high specificity and sensibility as well as relevant correlation with disease severity, progression, and response to therapy are awaited in inflammatory arthritides.

    MRI is sensitive for joint inflammation, but its ability to separate subgroups of arthritis in children has been questioned. Infectious arthritis (IA), postinfectious arthritis (PA), transient arthritis (TA) and juvenile idiopathic arthritis (JIA) are subgroups that may need early, different treatment. To determine whether MRI findings differ in IA, PA/TA and JIA in recent-onset childhood arthritis. Fifty-nine children from a prospective study of incidence of arthritis (n = 216) were, based on clinical and biochemical criteria, examined by MRI. Joint fluid, synovium, bone marrow, soft tissue and cartilage were scored retrospectively and analysed by Pearson chi-square test and logistic regression analysis. Fifty-nine children had MRI of one station. IA was suggested by bone marrow oedema (OR 7.46, P = 0.011) and absence of T1-weighted and T2-weighted low signal intensity synovial tissue (OR 0.06, P = 0.015). Furthermore, soft-tissue oedema and reduced contrast enhancement in the epiphyses were more frequent in children with IA. JIA correlated positively with low signal intensity synovial tissue (OR 13.30, P < 0.001) and negatively with soft-tissue oedema (OR 0.20, P = 0.018). No significant positive determinants were found for PA/TA, but bone marrow oedema, soft-tissue oedema, irregular thickened synovium and low signal intensity synovial tissue was less frequent than in IA/JIA. In children with high clinical suspicion of recent onset arthritis, there was a significant difference in the distribution of specific MRI features among the diagnostic groups. (orig.)

    2003-01-01

    Full Text Available Infectious laryngotracheitis (ILT herpesvirus continues to cause outbreaks of respiratory disease in chickens world-wide. Sporadic cases of ILT occur in all classes of birds, including hobby/show/game chickens, broilers, heavy breeders, and commercial laying hens. These epornitics of ILT tend to occur where there are large populations of naïve, unvaccinated birds, i.e., in concentrated areas of broiler production. ILT virus can be transmitted through (a chickens with acute upper respiratory tract disease, (b latently infected "carrier" fowls, and (c fomites and contaminated persons. Chicken flocks which are endemic infected with ILT virus occur only in some regions of countries or even in particular multiple-age production farms. In these cases modified live vaccines are actually used, even though these biological products, as well as wild ILTV strains, can establish latent infections. In the case of heavy breeders and laying hens, which are typically vaccinated against ILT, sporadic cases are often related to errors in vaccine application and to biosecurity failures.

Material and methods. 50 pts with IE (24 female, 26 male aged 16 to 60 years were included. Primary IE was diagnosed in 15, secondary - in 35 cases. 7 pts had acute and 43 — subacute course. 40 pts had definite and 10 — probable IE. Results. Mean period till correct diagnosis establishment was 112± 116,5 days. Diagnostic difficulties were more frequent in subacute variant of IE (p=0,03. Heart diseases prevailed among cardiac risk factors (p=0,0l. Clinical picture of IE was very polymorphous. Glucocorticoids (GC were administered to 21 pts in addition to antibiotics due to signs of organ immunopatology and high laboratory measures of immune activity. Positive effect of glucocorticoids was achieved in 64% of pts. Conclusion. Development of immunological changes complicates timely diagnosis of IE and requires exclusion of different diseases including rheumatic pathology. IE treatment strategy does not exclude administration of GC low doses for prominent immunopathological signs in addition to massive antibacterial therapy.

    Full Text Available If the diagnosis of the hip septic arthritis is delayed, serious complications such as the arthrosis in joint, the separation of epiphyseal, osteomyelitis and sepsis can develop. The presence of the accompanying infectious diseases contributes to the delay of the diagnosis. In order to get rid of the late period sequelaes of septic arthritis, the required tests should be asked for the differential diagnosis of this disease in each patient presenting with hip pain. In this paper we presented 13 years old pediatric patient who was treated with the diagnosis of pneumonia developed joint dislocation together with the physis separation of the femoral head because of delayed diagnosis of accompanying hip septic arthritis.

    2014-09-01

    A juvenile racing pigeon ( Columba livia ) was presented with drooping of the wing and inability to fly. On physical examination, the right shoulder joint was swollen. The pigeon was euthanatized and submitted for necropsy. An excessive amount of fibrin was present in the canalis triosseus with severe arthritis of the affected shoulder joint. A pure growth of Mycoplasma-like colonies was obtained on microbiological culture of the shoulder joint. A 16S ribosomal RNA gene-specific polymerase chain reaction assay was performed on the isolate and revealed 100% similarity with Mycoplasma columbinum . Although infectious arthritis in homing pigeons is primarily associated with paratyphoid and Streptococcus gallolyticus infection, clinical practitioners should consider the potential role of Mycoplasma columbinum in arthritis in pigeons.

  13. The Etiology of Juvenile Idiopathic Arthritis.

    Rigante, Donato; Bosco, Annalisa; Esposito, Susanna

    2015-10-01

    Over the years, the commonly used term to describe juvenile idiopathic arthritis (JIA) has changed. By definition, JIA includes all types of arthritis with no apparent cause, lasting more than 6 weeks, in patients aged less than 16 years at onset. JIA pathogenesis is still poorly understood: the interaction between environmental factors and multiple genes has been proposed as the most relevant working mechanism to the development of JIA. The concept that various microbes that colonize or infect not only the mucosal surfaces, like the oral cavity, but also the airways and gut might trigger autoimmune processes, resulting in chronic arthritides, and JIA was first drafted at the outset of last century. JIA development might be initiated and sustained by the exposure to environmental factors, including infectious agents which affect people at a young age, depending on the underlying genetic predisposition to synovial inflammation. Many data from patients with JIA suggest a scenario in which different external antigens incite multiple antigen-specific pathways, cytotoxic T cell responses, activation of classical complement cascade, and production of proinflammatory cytokines. In this review, emphasis is paid not only to the potential role of parvovirus B19 and Epstein-Barr virus in primis but also to the general involvement of different bacteria as Salmonella spp., Shigella spp., Campylobacter spp., Mycoplasma pneumoniae, Chlamydophila pneumoniae, Bartonella henselae, and Streptococcus pyogenes for the development of immune-mediated arthritides during childhood. No unequivocal evidence favoring or refuting these associations has been clearly proved, and today, the strict definition of JIA etiology remains unknown. The infection can represent a random event in a susceptible individual, or it can be a necessary factor in JIA development, always in combination with a peculiar genetic background. Further studies are needed in order to address the unsolved questions

    Full Text Available Juvenile rheumatoid arthritis (JRA is the most common rheumatic condition in children. JRA is defined as persistent arthritis in 1 or more joints for at least 6 weeks, with the onset before age 16 years. The etiology of JRA is unknown. Antigen activated CD4+ T cell stimulate monocytes, macrophages, and synovial fibroblasts to produce the cytokines Interleukin-1 (IL-1, IL-6, and tumor necrosis factor ? (TNF-? and to secrete matrix metalloproteinases, which lead to chronic inflammation due to infiltration of inflammatory cell, angiogenesis, destruction of cartilage and bone with pannus formation. The 3 major subtypes of JRA are based on the symptoms at disease onset and are designated systemic onset, pauciarticular onset, and polyarticular onset. For all patients, the goals of therapy are to decrease chronic joint pain and suppress the inflammatory process. Poor prognostic have been observed in patients with polyarticular onset, rheumatoid factor, persistent morning stiffness, tenosynovitis, involvement of the small joints, rapid appearance of erosions, active late onset childhood, subcutaneous nodules, or antinuclear antibody.

  15. Pain and microcrystalline arthritis

    Directory of Open Access Journals (Sweden)

    R. Ramonda

    2014-06-01

    Full Text Available Microcrystals are responsible for some of the most common and complex arthropathies which are often accompanied by intense, severe pain and inflammatory reactions. The main pathogens are crystals of monosodium urate (MSU, responsible for the gout, calcium pyrophosphate (CPP, which deposits also in various clinical forms of arthopathies, and basic calcium phosphate associated with osteoarthritis. In this context, the microcrystal arthritis is characterized by multiple, acute attacks followed by chronic pain, disability, impaired quality of life, and increased mortality. Given their chronic nature, they represent an ever more urgent public health problem. MSU and CPP crystals are also able to activate nociceptors. The pain in mycrocrystalline arthritis (MCA is an expression of the inflammatory process. In the course of these diseases there is an abundant release of inflammatory molecules, including prostaglandins 2 and kinins. Interleukin-1 represents the most important cytokine released during the crystal-induced inflammatory process. Therefore, clinically, pain is the most important component of MCA, which lead to functional impairment and disability in a large proportion of the population. It is fundamental to diagnose these diseases as early as possible, and to this aim, to identify appropriate and specific targets for a timely therapeutic intervention.

    To determine whether clinical, laboratory or Magnetic Resonance Imaging (MRI) measures differentiate Juvenile Idiopathic Arthritis (JIA) from other forms of active childhood arthritis. We prospectively collected data of 80 treatment-naive patients clinically suspected of JIA with active non-infectious arthritis of (at least) one knee for <12 months duration. Upon presentation patients underwent clinical and laboratory assessments and contrast-enhanced MRI. MRI was not used as a diagnostic criterion. Forty-four (55 %) patients were clinically diagnosed with JIA, whereas in 36 (45 %) patients the diagnosis of JIA was discarded on clinical or laboratory findings. MRI-based synovitis was present in 27 (61.4 %) JIA patients and in 7 (19.4 %) non-JIA patients (P < 0.001). Five factors (male gender, physician's global assessment of overall disease activity, joints with limited range of motion, HLA-B27, MRI-based synovitis) were associated with the onset of JIA. In multivariate analysis MRI-based synovitis proved to be independently associated with JIA (OR 6.58, 95 % CI 2.36-18.33). In patients with MRI-based synovitis, the RR of having JIA was 3.16 (95 % CI 1.6-6.4). The presence of MRI-based synovitis is associated with the clinical onset of JIA. Physical examination could be supported by MRI, particularly to contribute in the early differentiation of different forms of non-infectious childhood arthritis. (orig.)

    2015-01-01

    Psoriatic arthritis (PsA) is a heterogeneous condition with a myriad of different clinical presentations. It commonly affects the skin and musculoskeletal system causing psoriasis, peripheral arthritis, axial arthritis, enthesitis and dactylitis. Many patients also have related conditions, such as those within the metabolic syndrome and associated spondyloarthritis (SpA) conditions including inflammatory bowel disease and uveitis. Any therapeutic strategy must be tailored to the individual patient, taking into account her/his complete clinical presentation and comorbidities. New treatment recommendations from the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) provide evidence based recommendations on effective therapies for the management of each different manifestation of PsA, and how treatment may be affected by comorbidities (1). However, the limited evidence comparing different treatment strategies in PsA is recognised as a limitation in these recommendations and further information is detailed below.

    Full Text Available Psoriatic arthritis is a debilitating condition, which affects approximately one-quarter of psoriasis patients. Recent findings have furthered our understanding of the complex pathophysiology of PsA. There have been major advances in the identification of genes associated with joint involvement but not with cutaneous disease alone. The elucidation of key immunologic pathways has allowed the development of novel targeted therapies that are in the research pipeline. Currently, good screening tests and biomarkers to diagnose early PsA and to guide therapy are limited. In this paper, we present recent findings with regard to the immunopathogenesis and genetics of PsA, biomarkers, and screening tools and review the targeted therapies currently in clinical trials.

  9. Physiotherapy in rheumatoid arthritis.

    2004-05-17

    Rheumatoid arthritis (RA) is a chronic and painful clinical condition that leads to progressive joint damage, disability, deterioration in quality of life, and shortened life expectancy. Even mild inflammation may result in irreversible damage and permanent disability. The clinical course according to symptoms may be either intermittent or progressive in patients with RA. In most patients, the clinical course is progressive, and structural damage develops in the first 2 years. The aim of RA management is to achieve pain relief and prevent joint damage and functional loss. Physiotherapy and rehabilitation applications significantly augment medical therapy by improving the management of RA and reducing handicaps in daily living for patients with RA. In this review, the application of physiotherapy modalities is examined, including the use of cold/heat applications, electrical stimulation, and hydrotherapy. Rehabilitation treatment techniques for patients with RA such as joint protection strategies, massage, exercise, and patient education are also presented.

    Full Text Available Rheumatoid arthritis (RA and juvenile idiopathic/rheumatoid arthritis (JIA are chronic, inflammatory, systemic, auto-immune diseases characterized by chronic arthritis leading to progressive joint erosions. The individual functional and social impact of rheumatoid arthritis is of great importance. Disability and joint damage occur rapidly and early in the course of the disease. The remarkably improved outcomes have been achieved initiating biologic therapy with close monitoring of disease progression. Biologic agents are drugs, usually proteins, which can influence chronic immune dysregulation resulting in chronic arthritis. According to the mechanism of action these drugs include: 1 anti-TNF drugs (etanercept, infiximab, adalimumab; 2 IL-1 blocking drugs (anakinra; 3 IL-6 blocking drugs (tocilizumab; 4 agents blocking selective co-stimulation modulation (abatacept; 5 CD 20 blocking drugs (rituximab. Biologics targeting TNF-alpha with methotrexate have revolutionized the treatment of RA, producing significant improvement in clinical, radiographic, and functional outcomes not seen previously. The new concept of rheumatoid arthritis treatment defines early diagnosis, early aggressive therapy with optimal doses of disease modifying antirheumatic drugs (DMARDs and, if no improvement has been achieved during six months, early introduction of biologic drugs. The three-year experience of biologic therapy in Serbia has shown a positive effect on disease outcome.

The medical assessment and reduction of cardiovascular risks, the prevention of infectious complications, hemorrhages, and lower extremity deep vein thrombosis, and the specific features of management of patients with osteoporosis are under consideration. The authors' experience in managing the patients receiving antirheumatic therapy with nonsteroidal antiinflammatory and disease-modifying antirheumatic drugs, such as methotrexate, leflunomide, sulfasalazine, and hydroxychloroquine, is detailed. Recommendations for managing patients taking glucocorticoids and biologic agents (tumor necrosis factor-α inhibitors, anti-B-cell therapy, and interleukin-6 receptor inhibitors in the preoperative andpostoperative periods are given.

  16. [Juvenile idiopathic arthritis: Definition and classification].

    Science.gov (United States)

    Deslandre, C

    2016-04-01

    Juvenile idiopathic arthritis (JIA) is a group of diseases defined by the presence of arthritis of more than 6 weeks duration in patients aged less than 16 years and with unknown etiology. The international classification based on clinical and biological criteria define each type of JIA: systemic, oligoarticular, polyarticular with and without rheumatoid factor, enthesitis-related arthritis, and psoriatic arthritis. However, some discussions persist concerning systemic-onset juvenile idiopathic arthritis, whose clinical symptoms and pathogenic mechanisms are quite similar to those observed in autoinflammatory diseases, arthritis with antinuclear factors (poly- and oligoarticular) that could be considered as a homogenous group, and a family history of psoriasis that frequently led to unclassified arthritis. Better knowledge of the pathogenic mechanisms should improve the initial clinical classification with more homogeneous groups of patients and reduce the number of unclassified cases of arthritis.

    Emerging infectious diseases (EID) are defined as diseases that have appeared recently or that have recently increased in their frequency, geographical distribution or both. Commercial globalisation, population movements and environmental changes are the main factors favouring the international spread of microorganisms. Transport and communication development constitutes also a remarkable factor in the worldwide dispersion of microorganisms. The mass movement of large numbers of people creates new opportunities for the spread and establishment of common or novel infectious diseases. A surveillance system to detect emergent and re-emergent infections, a rapid responsiveness of healthcare systems and laboratories, vector control, and the provision of healthcare education programmes to inform the population of how to avoid infections are needed in order to stop the spread of infectious diseases.

    Full Text Available Infectious disease, especially virulent infectious disease, is commonly regarded as a cause of fluctuation or decline in biological populations. However, it is not generally considered as a primary factor in causing the actual endangerment or extinction of species. We review here the known historical examples in which disease has, or has been assumed to have had, a major deleterious impact on animal species, including extinction, and highlight some recent cases in which disease is the chief suspect in causing the outright endangerment of particular species. We conclude that the role of disease in historical extinctions at the population or species level may have been underestimated. Recent methodological breakthroughs may lead to a better understanding of the past and present roles of infectious disease in influencing population fitness and other parameters.

    Full Text Available Rheumatoid arthritis (RA is a chronic disease characterized by inflammation of the synovial joints, and loss of the function leading to disability. The ultimate goal in managing RA is to prevent joint damage and to maintain functional ability. Although, οver the past decade, major advances have been made in our understanding of the factors that are crucial in regulating this disease, still the managment of the disease remains difficult.Aim : Τhe aim of the present study was the evaluation of the therapeutical approch on rheumatoid arthritis. The method οf this study included bibliography research from both the review and the research literature which referred to the relation between therapy and rheumatoid arthritis.Results : The majority of research studies showed thatthe main therapy on rheumatoid arthritis included medication therapy, modification of everyday living ensuring rest, physical exercise and finally surgical procedure. Individuals suffering from rheumatoid arthritis, apart from physical problems usually cope with mental disorders, that exert a negative indluence on their quality of life.Conclusively :Information and early screening of high risk may decrease the long-term consequnences on health. Monitoring from a group of specialists should serve as a cornerstone when planning a program of intervention.

    Plain films remain the basic tool for diagnosis and follow-up evaluation of juvenile idiopathic arthritis (JIA). In this paper, we review the new classification of JIA: systemic arthritis, oligoarthritis (persistent), oligoarthritis (extended), polyarticular arthritis (rheumatoid factor negative), polyarticular arthritis (rheumatoid factor positive), enthesitis related arthritis, psoriatic arthritis and unclassified arthritis. We will also review regional abnormalities of three stages: an early stage, an intermediate stage, a late stage, as well as the differential diagnosis.

    2012-06-01

    Full Text Available Imaging techniques to assess psoriatic arthritis (PsA include radiography, ultrasonography (US, magnetic resonance imaging (MRI, computed tomography (CT and bone scintigraphy. The radiographic hallmark of PsA is the combination of destructive changes (joint erosions, tuft resorption, osteolysis with bone proliferation (including periarticular and shaft periostitis, ankylosis, spur formation and non-marginal syndesmophytes. US has an increasing important role in the evaluation of PsA. In fact, power Doppler US is useful mainly for its ability to assess musculoskeletal (joints, tendons, entheses and cutaneous (skin and nails involvement, to monitor efficacy of therapy and to guide steroid injections at the level of inflamed joints, tendon sheaths and entheses. MRI allows direct visualization of inflammation in peripheral and axial joints, and peripheral and axial entheses, and has dramatically improved the possibilities for early diagnosis and objective monitoring of the disease process in PsA. MRI has allowed explaining the relationships among enthesitis, synovitis and osteitis in PsA, supporting a SpA pattern of inflammation where enthesitis is the primary target of inflammation. CT has little role in assessment of peripheral joints, but it may be useful in assessing elements of spine disease. CT accuracy is similar to MRI in assessment of erosions in sacroiliac joint involvement, but CT is not as effective in detecting synovial inflammation. Bone scintigraphy lacks specificity and is now supplanted with US and MRI techniques.

  4. Prostaglandins and Rheumatoid Arthritis

    Directory of Open Access Journals (Sweden)

    Mohammad Javad Fattahi

    2012-01-01

    Full Text Available Rheumatoid arthritis (RA is a chronic, autoimmune, and complex inflammatory disease leading to bone and cartilage destruction, whose cause remains obscure. Accumulation of genetic susceptibility, environmental factors, and dysregulated immune responses are necessary for mounting this self-reacting disease. Inflamed joints are infiltrated by a heterogeneous population of cellular and soluble mediators of the immune system, such as T cells, B cells, macrophages, cytokines, and prostaglandins (PGs. Prostaglandins are lipid inflammatory mediators derived from the arachidonic acid by multienzymatic reactions. They both sustain homeostatic mechanisms and mediate pathogenic processes, including the inflammatory reaction. They play both beneficial and harmful roles during inflammation, according to their site of action and the etiology of the inflammatory response. With respect to the role of PGs in inflammation, they can be effective mediators in the pathophysiology of RA. Thus the use of agonists or antagonists of PG receptors may be considered as a new therapeutic protocol in RA. In this paper, we try to elucidate the role of PGs in the immunopathology of RA.

    Full Text Available Rheumatoid arthritis (RA generally starts at the age when many women have already become mothers; however, it may occur in childhood or adolescence. Furthermore, there has been recently a women’s tendency to plan pregnacy for a more mature age, which necessitates a discussion about gestation in this disease. Investigation of mechanisms pregnancy can influence the development of RA both in the gestation and long-term periods is of important theoretical and practical value. The results of these investigations may be used to develop new treatments for RA and management tactics for patients during pregnancy and lactation. The  aper gives the data available in the literature on fertility in RA, impact of pregnancy on its activity and that of RA on the course and outcomes of gestation, as well as current ideas on lactation and use of oral contraceptives in RA. Particular attention is given to drug therapy in pregnant and breastfeeding women with RA: groups of anti-rheumatic drugs are considered in detail in relation to the safety of or a potential risk from their use. A therapeutic algorithm and recommendations for pregnancy planning and a follow-up of patients with RA during gestation are proposed.

    Infectious diseases are still among the leading causes of death worldwide due to their persistence, emergence, and reemergence. As the recent Ebola virus disease and MERS-CoV outbreaks demonstrate, the modern epidemics and large-scale infectious outbreaks emerge and spread quickly. Air transportation is a major vehicle for the rapid spread and dissemination of communicable diseases, and there have been a number of reported outbreaks of serious airborne diseases aboard commercial flights including tuberculosis, severe acute respiratory syndrome, influenza, smallpox, and measles, to name a few. In 2014 alone, over 3.3 billion passengers (a number equivalent to 42% of the world population) and 50 million metric tons of cargo traveled by air from 41,000 airports and 50,000 routes worldwide, and significant growth is anticipated, with passenger numbers expected to reach 5.9 billion by 2030. Given the increasing numbers of travelers, the risk of infectious disease transmission during air travel is a significant concern, and this chapter focuses on the current knowledge about transmission of infectious diseases in the context of both transmissions within the aircraft passenger cabin and commercial aircraft serving as vehicles of worldwide infection spread.

    Objective: To determine the spectrum of clinical presentation, laboratory parameters and drug therapy in patients with Juvenile Rheumatoid Arthritis (JRA). Study Design: Case series. Place and Duration of Study: The Children's Hospital and The Institute of Child Health, Lahore, from October 2008 to October 2011. Methodology: All patients who fulfilled the American College of Rheumatology criteria for JRA were enrolled. Their clinical features, investigations done and treatment received for JRA were noted. Statistical analysis of data was done on SPSS version 16.0 for obtaining descriptive statistics. Results: Out of 185 patients, 50.3% (n = 93) were females; 54% (n = 100) were between 10 - 15 years of age. Polyarthritis was found in 71.9% (n = 133) followed by oligoarthritis (22.7%, n = 42) and systemic onset disease (5.4%, n = 10). Morning stiffness (78%) and fever (68%) were the most common clinical presentations. All patients with systemic onset disease had fever (n = 10) followed by skin rash, hepatosplenomegaly and lymphadenopathy. Uveitis was found in 2 patients, and both belonged to the oligoarticular group. Rheumatoid factor was found in 10.27% (n = 19) of all patients. All patients were given non-steroidal anti-inflammatory drugs (NSAIDs). Disease modifying agents (methotrexate) were given to 43.8% (n = 81). Steroids were used in 61% (n = 113) of patients either with NSAIDs alone or NSAIDs plus methotrexate. Conclusion: Disease profile of JRA at the study centre showed that polyarthritis is the commonest type. Recognition of subtypes will help in planning the management of these patients. (author)

    Full Text Available Septic arthritis is an Orthopaedic emergency, threatening the joint within hours of onset. Up to 10% of cases of meningococcaemia have an associated septic arthritis. The aetiology of acute meningococcaemia in a variety of clinical syndromes is well documented in the literature. The pathogen Neisseria meningitidis can cause both primary and secondary manifestations of disseminated infection. Broad-range 16S rDNA PCR is a relatively new technique, useful in identifying aetiological agents in septic patients with negative blood cultures. Here, we describe the rare clinical scenario of a 76-year-old woman with primary meningococcal septic arthritis of a native shoulder joint without associated meningococcal bloodstream infection. We discuss the role of 16s rDNA Polymerase Chain Reaction (PCR in the identification of the infectious agent, Neisseria meningitidis, and the role of this technique in guiding subsequent management.

  13. Transarticular spread of Ewing sarcoma mimicking septic arthritis

    International Nuclear Information System (INIS)

    Transarticular spread of tumor is rare; it has only been reported in the sacroiliac joint, intervertebral disk spaces, and facet joints. The anatomic and kinetic characteristics of the sacroiliac joint, as well as the changes the joint undergoes during a lifetime, make it particularly vulnerable to transarticular tumor invasion. Although extremely rare, Ewing sarcoma can extend through the sacroiliac joint and be virtually indistinguishable radiologically from septic arthritis. Furthermore, the clinical presentation of a child with Ewing sarcoma can be similar to that of a child with osteomyelitis. Laboratory values are quite nonspecific and are not always helpful in differentiating between the entities. Therefore, the possibility of sacroiliac joint transarticular Ewing sarcoma should be considered in a child presenting with hip pain, despite clinical, radiological and laboratory findings suggesting an infectious process.

    Full Text Available R John LooneyUniversity of Rochester, Rochester, New York, USAAbstract: It has been 3 years since rituximab, a mouse x human chimeric anti-CD20 monoclonal antibody that selectively depleted B cells, was approved by the FDA for the treatment of moderate to severe rheumatoid arthritis (RA with an inadequate response to anti-TNF therapies. Since approval rituximab has become a part of standard treatment, and additional data have become available on long-term efficacy and safety both from clinical trials and from post-marketing surveillance. In open long-term follow-up from clinical trials, patients treated with multiple courses of rituximab continued to respond in terms of signs and symptoms, and damage assessed radiographically was significantly inhibited. Moreover, the rate of serious infectious events was not increased as the number of courses increased. However, because of case reports of progressive multifocal leukoencephalopathy in patients treated with rituximab for non-malignant conditions, a black box warning has been added. Studies on the immunologic correlates of response to rituximab treatment including B cell subsets in peripheral blood and synovial biopsies are providing clues into how rituximab works for autoimmune disease. However, at this time we are not able to explain why some patients do not respond and cannot predict who will respond. Future challenges for the further development of rituximab for intractable RA will be discussed.Keywords: rheumatoid arthritis, rituximab, B cells, immunocompetency

    In this paper the molecular aspects of the relationships between infectious agents and autoimmune diseases, the mechanisms of immune response to infectious agents, and the more recent hypotheses regarding the cause of autoimmune diseases are discussed. The antigens are processed and selected by their immunogenicity, and presented by HLA molecules to the T cell receptor. These events initiate the immune response with the activation and proliferation of T-lymphocytes. Although there are several hypotheses regarding the cause of autoimmune diseases and too many findings against and in favor of them, there is still no conclusive data. All these hypothesis and findings are discussed in the context of the more recent advances. PMID:1615352

    Bronchiolitis is a common early childhood illness and an important cause of morbidity, it is the number one cause of hospitalization among US infants. Bronchiolitis is also an active area of research, and recent studies have advanced our understanding of this illness. Although it has long been the conventional wisdom that the infectious etiology of bronchiolitis does not affect outcomes, a growing number of studies have linked specific pathogens of bronchiolitis (e.g., rhinovirus) to short- and long-term outcomes, such as future risk of developing asthma. The authors review the advent of molecular diagnostic techniques that have demonstrated diverse pathogens in bronchiolitis, and they review recent studies on the complex link between infectious pathogens of bronchiolitis and the development of childhood asthma.

  8. CT evaluation of infectious colitis

    International Nuclear Information System (INIS)

    Computed tomography (CT) is useful for evaluating the diagnosis of gastrointestinal disease, such as infectious colitis, in patients with severe pain and bloody diarrhea. During the 7 years between November 1993 and October 2000, 34 patients with infectious colitis (18 male, 16 female; mean age 42±19 yrs), received emergency CT and colonoscopy because of severe abdominal pain and dysentery. The following organisms were isolated: pathogenic Escherichia coli (12), 6 of which were O157: H7 (O-157), Salmonella species (11), Campylobacter species (5), Vibrio parahaemolyticus (3), Yersinia enterocolotica (2) and Shigella species (1). Thickening of the intestinal wall greater than 10 mm was seen in the ascending colon in the 6 cases with E. coli O157, in 5/11 cases with Salmonella, 4/5 with Campylobacter and 1/6 with non-O157 pathogenic E. Coli. marked intestinal wall thickening, greater than 20 mm, was seen in the ascending colon of the 4 of the patients with an O-157 infection. In all patients with O-157 colitis, slight ascites was noted in the pelvic space. In additions, ascites was also seen in 3/13 patients with Salmonella and 1/5 patients with Campylobacter colitis. The CT findings, in the patients with infectious colitis, are non-specific but knowledge and recognition of the findings will help in patient evaluation and proper treatment. (author)

    Full Text Available We examined 1824 patients with diphtheria treated in Clinical Infectious Diseases Hospital Botkin (St. Petersburg in 1993 – 1994, and more than 500 patients referred to the clinic with a diagnosis of «angina». Based on published data and our own research observations investigated the etiology of acute tonsillitis. Bacterial tonsillitis should be treated with antibiotics, and this is important aetiological interpretation of these diseases. Streptococcal tonsillitis should always be a sore throat syndrome as a diagnostic sign of support. For other forms of lymphoma lesion of the tonsils should not be defined as «angina», and called «tonsillitis». Аngina as β-hemolytic streptococcus group A infection is recognized as the leader in the development of rheumatic fever. On the basis of a large clinical material briefly analyzed the clinical manifestations of various forms of diphtheria with membranous tonsillitis.

    Perumal, B; Black, E H; Levin, F; Servat, J J

    2012-05-01

    Non-infectious vasculitides comprise a large number of diseases. Many of these diseases can cause inflammation within the orbit and a clinical presentation, which mimics numerous other processes. Orbital disease can often be the initial presentation of a systemic process and early diagnosis can help prevent long-term, potentially fatal consequences. The evaluation and treatment of non-infectious orbital vasculitides are often complicated and require a thorough understanding of the disease and underlying systemic associations. The long-term prognosis visually and systemically must be weighed against the risks and benefits of the treatment regimen. A large variety of corticosteroid formulations currently exist and are the mainstay of initial treatment. Traditional steroid-sparing immunosuppressive agents are also an important arsenal against these vasculitides. Recently, a new class of drugs called biologics, which target the various mediators of the inflammation cascade, may potentially provide more effective and less toxic treatment. This review aims to synthesize the current literature on non-infectious orbital vasculitides. PMID:22361845

    Acromioclavicular (AC) and sternoclavicular (SC) septic arthritis with contiguous pyomyositis are rare, especially in immunocompetent individuals. We report a case of septic AC joint with pyomyositis of the deltoid and supraspinatus muscles and a separate case with septic SC joint with pyomysitis of the sternocleidomastoid muscle. Both patients had similar presentations of infections with Staphylococcus aureus and were successfully treated with surgical incision and drainage followed by prolonged antibiotic therapy.

  14. Genetics of psoriatic arthritis.

    2014-10-01

    Spondyloarthritis (SpA) represents a group of inflammatory rheumatic diseases that cluster within families and possess overlapping clinical features. The pathogenesis of SpA encompasses a complex array of genetic, immunological and environmental factors. In this article, we will briefly review the genetics of PsA, and then focus on the genes that may be potentially linked either directly or indirectly to the immunopathology of the Th-17 pathway. The most consistent and dominant genetic effect of PsV and PsA is located on chromosome 6p21.3 within the major histocompatibility complex (MHC) region, which accounts for approximately one-third of the genetic contribution of PsV and PsA. To date, 36 genes have reached genome-wide significance, accounting for approximately 22% of psoriasis (PsV) heritability. Prominent genes identified via GWAS include HLA-Cw6, IL12B, IL23R, IL23A, TNIP1, TNFAIP3, LCE3B-LCE3C, TRAF3IP2, NFkBIA, FBXL19, TYK2, IFIH1, REL, and ERAP1. Genes identified in psoriatic arthritis (PsA) has largely echoed those in PsV and include HLA-B/C, HLA-B, IL-12B, IL-23R, TNIP1, TRAF3IP2, FBXL19, and REL. The lack of identified genetic susceptibility loci is largely attributed to the much smaller number of PsA patients and the greater clinical heterogeneity of PsA. Searching for different types of genetic variants such as small CNVs and/or insertions/deletions has also led to the identification of several genes with a function relative to PsV in particular including DEFB4, LCE3C_LCE3B, and IL-22 gene (exon 1). The candidate genes identified in PsV/PsA have highlighted pathways of critical importance to psoriatic disease including distinct signaling pathways comprised of barrier integrity, innate immune response and adaptive immune response, mediated primarily by Th-17 and Th-1 signalling. While GWAS studies have yielded great insights into the genes that contribute to the pathogenesis of PsV and PsA, replication in large cohorts, fine-mapping and resequencing

    Septic arthritis has long been considered an orthopedic emergency. Historically, Neisseria gonorrhoeae and Staphylococcus aureus have been the most common causes of septic arthritis worldwide but in the modern era of biological therapy and extensive use of prosthetic joint replacements, the spectrum of microbiological causes of septic arthritis has widened considerably. There are also new approaches to diagnosis but therapy remains a challenge, with a need for careful consideration of a combined medical and surgical approach in most cases.

  19. Rheumatoid arthritis and the role of oral bacteria

    Directory of Open Access Journals (Sweden)

    Juan Pablo Loyola-Rodriguez

    2010-12-01

    Full Text Available Rheumatoid arthritis (RA and periodontal disease (PD have shown similar physiopathologic mechanisms such as chronic inflammation with adjacent bone resorption in an immunogenetically susceptible host; however, PD has a well-recognized bacterial etiology while the cause of RA is unclear. Some reports have indicated that an infectious agent in a susceptible host could be one possible trigger factor for RA, and it has been suggested that oral microorganisms, specialty periodontal bacteria could be the infectious agent (mainly Porphyromonas gingivalis. It has been reported that PD is more frequent and more severe in patients with RA, suggesting a positive association between both diseases. There have been reports regarding the detection of antibodies against periodontal bacteria while other studies have identified periodontal bacterial DNA in serum and synovial fluid of RA patients and have explored the possible pathways of transport of periodontal bacterial DNA. In conclusion, there is no question that RA and PD have pathologic features in common and there is strong evidence of an association between both diseases, but further studies, including experimental models, are needed to demonstrate the arthritogenicity of oral microorganisms.

  20. Investigative modalities in infectious keratitis

    2008-01-01

    Full Text Available Standard recommended guidelines for diagnosis of infectious keratitis do exist. Based on an extensive Medline literature search, the various investigative modalities available for aiding the diagnosis of microbial keratitis have been reviewed and described briefly. Preferred practice patterns have been outlined and the importance of routine pre-treatment cultures in the primary management of infectious keratitis has been highlighted. Corneal scraping, tear samples and corneal biopsy are few of the specimens needed to carry out the investigative procedures for diagnosis and for initiating therapy in cases of microbial keratitis. In bacterial, fungal and amoebic keratitis, microscopic examination of smears is essential for rapid diagnosis. Potassium hydroxide (KOH wet mount, Gram′s stain and Giemsa stain are widely used and are important for clinicians to start empirical therapy before microbial culture results are available. The usefulness of performing corneal cultures in all cases of suspected infectious keratitis has been well established. In cases of suspected viral keratitis, therapy can be initiated on clinical judgment alone. If a viral culture is needed, scrapings should directly be inoculated into the viral transport media. In vivo confocal microscopy is a useful adjunct to slit lamp bio-microscopy for supplementing diagnosis in most cases and establishing early diagnosis in many cases of non-responding fungal and amoebic keratitis. This is a non-invasive, high resolution technique which allows rapid detection of Acanthamoeba cysts and trophozoites and fungal hyphae in the cornea long before laboratory cultures give conclusive results. Other new modalities for detection of microbial keratitis include molecular diagnostic techniques like polymerase chain reaction, and genetic finger printing by pulsed field gel electrophoresis.

    2014-06-01

    Management of fungal osteomyelitis and fungal septic arthritis is challenging, especially in the setting of immunodeficiency and conditions that require immunosuppression. Because fungal osteomyelitis and fungal septic arthritis are rare conditions, study of their pathophysiology and treatment has been limited. In the literature, evidence-based treatment is lacking and, historically, outcomes have been poor. The most common offending organisms are Candida and Aspergillus, which are widely distributed in humans and soil. However, some fungal pathogens, such as Histoplasma, Blastomyces, Coccidioides, Cryptococcus, and Sporothrix, have more focal areas of endemicity. Fungal bone and joint infections result from direct inoculation, contiguous infection spread, or hematogenous seeding of organisms. These infections may be difficult to diagnose and eradicate, especially in the setting of total joint arthroplasty. Although there is no clear consensus on treatment, guidelines are available for management of many of these pathogens.

  2. Tyrosine kinases in rheumatoid arthritis

    Kobayashi Akiko

    2011-08-01

    Full Text Available Abstract Rheumatoid arthritis (RA is an inflammatory, polyarticular joint disease. A number of cellular responses are involved in the pathogenesis of rheumatoid arthritis, including activation of inflammatory cells and cytokine expression. The cellular responses involved in each of these processes depends on the specific signaling pathways that are activated; many of which include protein tyrosine kinases. These pathways include the mitogen-activated protein kinase pathway, Janus kinases/signal transducers and activators transcription pathway, spleen tyrosine kinase signaling, and the nuclear factor κ-light-chain-enhancer of activated B cells pathway. Many drugs are in development to target tyrosine kinases for the treatment of RA. Based on the number of recently published studies, this manuscript reviews the role of tyrosine kinases in the pathogenesis of RA and the potential role of kinase inhibitors as new therapeutic strategies of RA.

    Full Text Available Rheumatoid arthritis is a systemic autoimmune disease, mainly poli-artycular, among wide-spread chronic inflammatory diseases, that cause pain, functional limitation, damage and joints deformations, and disability. It is characterized by turns of active inflammation and remission phases. Inflammation degree and persistence are associated to a bad functional prognosis and progressive joint disability. These patients management require a continuous valuation of inflammatory activity index of disease both therapeutic management and to prevent disablement process. We focus on many valuation index of joint disability and functional damage. Very important are both the scales of auto-values concerning the pain and the joint swelling and clinical data get by physician to valuate activity index of disease as defined by DAS28. Significant data come by health-related quality of life, disability and by AIMS2 (Arthritis Impact Measurement Scale.

    The musculoskeletal system can be affected by a variety of abnormalities in association with human immunodeficiency virus (HIV) infection. Although not as common as complications involving other organ systems, such as the pulmonary and the central nervous systems, HIV-associated musculoskeletal disorders are sometimes the initial presentation of the viral illness. Knowledge of the existence and the characteristic appearance of the conditions affecting bone, joint, and muscle in HIV-infected patients is valuable to radiologists for diagnosis and to clinicians for detection and appropriate treatment. We reviewed recent literature to provide a comprehensive assessment of the HIV-associated musculoskeletal disorders, and present radiologic examples from our own collection. This article is divided into two parts. In the first part we review the infectious musculoskeletal disorders associated with HIV illness and AIDS, including cellulitis, abscesses, pyomyositis, septic bursitis, septic arthritis, osteomyelitis, and bacillary angiomatosis. We also present a comprehensive spectrum of mycobacterial infections, consisting of tuberculous spondylitis and spondylodiskitis, arthritis, osteomyelitis, and tenosynovitis, as well as infections caused by atypical mycobacteria.

    Full Text Available Atherosclerosis is a chronic inflammatory disease of the arteries. Clinical consequences of the atherosclerotic process occur in the adult population, however atherosclerotic process begins in childhood. The classic risk factors for atherosclerosis include obesity, dyslipidaemia, age, gender or family history. In recent years, attention has been drawn to the similarity between atherosclerotic inflammatory processes and inflammatory changes in the course of systemic connective tissue disease, in particular systemic lupus etythematosus (SLE or rheumatoid arthritis (RA. There is also observed the similarity of the pathogenetic background of development of atherosclerosis and juvenile idiopathic arthritis (JIA. Elevated levels of pro-inflammatory cytokines are observed in the course of juvenile idiopathic arthritis. Also homocysteine concentrations, which may play a significant role in the development of atherosclerotic lesions, are observed higher in patients with JIA. Some studies revealed higher carotid intima-media thickness (IMT index values in children with JIA. In view of the fact that atherosclerotic process begins as early as in childhood, the introduction of appropriate preventive measures in children is a matter of utmost importance.

    Full Text Available The article deals with the issue of psychic problems of rheumatoid arthritis patients. Rheumatoid arthritis is a chronic, inflammatory motor system disease with comprehensive impact on the patient's life. The disease is often considered an exclusively physical disease. But such approach is insufficient because the disease is accompanied by motor limitations of different intensities, by pain and by fatigue that cause considerable exhaustion to the patient. The patients often must give up their hobbies and in some cases even their jobs. In most serious cases, even common daily activities including self–servicing actions become an obstacle to the patient. It is therefore logical that the psyche of a patient with such disease is considerably strained. One of the partial goals of the study consisted in mapping the subjectively perceived quality of life of rheumatoid arthritis patients in facet 8, "negative feelings", and in ascertaining whether there is statistically significant relation to facets 1, "pain and discomfort", and 2, "energy and fatigue". Another goal consisted in comparing the subjectively perceived quality of life between men and women with rheumatoid arthritis, as well as between population of rheumatoid arthritis patients and control healthy population. The study was implemented within the research project of the Grant Agency of the University of South Bohemia in České Budějovice number 120/2012/S, „Reflection of quality of life in nursing", under use of two standardized questionnaires, WHOQOL–100 and HAQ.

    2016-05-01

    Juvenile idiopathic arthritis is the most common rheumatic disease in childhood. It is a chronic inflammatory disease associated with arthritis of unknown etiology that begins before the age of 16 and persists for longer than 6 weeks. In this report, the case of a child who suffered recurrent alternative hip arthritis with bilateral hip arthritis is examined, in which he was finally diagnosed as suffering from Juvenile idiopathic arthritis. A 14-year-old boy of Taiwanese origin presented with a normal birth and developmental history. At the age of 10, right-side hip joint pain was experienced, which later migrated to the left side. On further inspection, synovium hypertrophy, cartilage erosion and hip turbid fluid accumulation were found and aseptic arthritis was presumed to be the primary cause. However, after re-examining both his clinical history and presentation, Juvenile idiopathic arthritis was the final diagnosis. Any child presenting with repeat joint swelling are at risk of Juvenile idiopathic arthritis. This is still to be the case if symptoms recede or heal and no initial diagnosis is made. Therefore, a better understanding of the risk of recurrent arthritis is needed. It cannot be emphasized strongly enough that Juvenile idiopathic arthritis should be suspected at all times when a child suffers from recurrent aseptic arthritis of the hip joint.

    Current diagnostic methods in differentiating septic from non-septic arthritis are time-consuming (culture) or have limited sensitivity (Gram stain). Microcalorimetry is a novel method that can rapidly detect microorganisms by their heat production. We investigated the accuracy and time to detection of septic arthritis by using microcalorimetry. Patients older than 18 years of age with acute arthritis of native joints were prospectively included. Synovial fluid was aspirated and investigated by Gram stain, culture and microcalorimetry. The diagnosis of septic arthritis and non-septic arthritis were made by experienced rheumatologists or orthopaedic surgeons. Septic arthritis was diagnosed by considering the finding of acute arthritis together with findings such as positive Gram stain or positive culture of synovial fluid or positive blood culture. The sensitivity and specificity for diagnosing septic arthritis and the time to positivity of microcalorimetry were determined. Of 90 patients (mean age 64 years), nine had septic arthritis, of whom four (44 %) had positive Gram stain, six (67 %) positive synovial fluid culture and four (44 %) had positive blood culture. The sensitivity of microcalorimetry was 89 %, the specificity was 99 % and the mean detection time was 5.0 h (range, 2.2-8.0 h). Microcalorimetry is an accurate and rapid method for the diagnosis of septic arthritis. It has potential to be used in clinical practice in diagnosing septic arthritis.

The pretravel medical consultation includes immunizations, malaria chemoprophylaxis, self-treatment for traveler's diarrhea, and advice on the prevention of a myriad of other infectious causes including dengue, chikungunya, rickettsiosis, leptospirosis, schistosomiasis, and strongyloidiasis. Travel to locations experiencing outbreaks such as Ebola virus disease, Middle East respiratory syndrome, avian influenza, and chikungunya call for specific alerts on preventive strategies. After travel, evaluation of an ill traveler must explore details of exposure, including destinations visited; activities; ingestion of contaminated food or drinks; contact with vectors, animals, fresh water, or blood and body fluids; and other potential exposures. Knowledge of the geographic distribution of infectious diseases is important in generating the differential diagnoses and testing accordingly. Empiric treatment is sometimes necessary when suspicion of a certain diagnosis is strong and confirmatory tests are delayed or lacking, particularly for infections that are rapidly progressive (for example, malaria) or for which timing of testing is prolonged (such as leptospirosis).

  1. Biomarkers for rheumatoid and psoriatic arthritis.

    Science.gov (United States)

    Verheul, M K; Fearon, U; Trouw, L A; Veale, D J

    2015-11-01

    Rheumatic diseases, such as rheumatoid and psoriatic arthritis are systemic inflammatory conditions characterized by a chronic form of arthritis, often leading to irreversible joint damage. Early treatment for patients with rheumatic diseases is required to reduce or prevent joint injury. However, early diagnosis can be difficult and currently it is not possible to predict which individual patient will develop progressive erosive disease or who may benefit from a specific treatment according to their clinical features at presentation. Biomarkers are therefore required to enable earlier diagnosis and predict prognosis in both rheumatoid arthritis and psoriatic arthritis. In this review we will examine the evidence and current status of established and experimental biomarkers in rheumatoid and psoriatic arthritis for three important purposes; disease diagnosis, prognosis and prediction of response to therapy.

  2. Photoacoustic tomography to identify inflammatory arthritis

    2012-09-01

    Identifying neovascularity (angiogenesis) as an early feature of inflammatory arthritis can help in early accurate diagnosis and treatment monitoring of this disease. Photoacoustic tomography (PAT) is a hybrid imaging modality which relies on intrinsic differences in the optical absorption among the tissues being imaged. Since blood has highly absorbing chromophores including both oxygenated and deoxygenated hemoglobin, PAT holds potential in identifying early angiogenesis associated with inflammatory joint diseases. PAT is used to identify changes in the development of inflammatory arthritis in a rat model. Imaging at two different wavelengths, 1064 nm and 532 nm, on rats revealed that there is a significant signal enhancement in the ankle joints of the arthritis affected rats when compared to the normal control group. Histology images obtained from both the normal and the arthritis affected rats correlated well with the PAT findings. Results support the fact that the emerging PAT could become a new tool for clinical management of inflammatory arthritis.

  3. Psoriatic arthritis: from pathogenesis to therapy.

    LENUS (Irish Health Repository)

    Fitzgerald, Oliver

    2012-02-01

    Psoriatic arthritis is a multigenic autoimmune disease that involves synovial tissue, entheseal sites and skin, and that may result in significant joint damage. Although there are no diagnostic tests for psoriatic arthritis, research has identified consistent features that help to distinguish the condition from other common rheumatic diseases. Comparison of HLA-B and HLA-C regions in psoriatic arthritis with those in psoriasis without joint involvement demonstrates significant differences, such that psoriatic arthritis cannot be viewed simply as a subset of genetically homogeneous psoriasis. T-cell receptor phenotypic studies have failed to identify antigen-driven clones, and an alternative hypothesis for CD8 stimulation involving innate immune signals is proposed. Finally, imaging studies have highlighted entheseal involvement in psoriatic arthritis, and it is possible that entheseal-derived antigens may trigger an immune response that is critically involved in disease pathogenesis.

  4. Infectious diseases associated with caves.

    Igreja, Ricardo Pereira

    2011-06-01

    In recent times, caving has become increasingly popular, with almost 2 million people visiting national park caves each year in the United States. Although the 2 million tourist visits are extremely low risk, smaller numbers of sport cavers are at risk for some high risk conditions, and expedition cavers are at risk for some obscure infections. Infectious diseases like histoplasmosis, rabies, leptospirosis, and tick-borne relapsing fever may be transmitted by the underground fauna. To reduce the risk of illness or injury while caving, knowledge of potential risks before engaging in this activity is important. Caving preparation needs to be carefully planned and executed, including vaccinations, prophylactic medications, and advice regarding safe conduct and behaviors. PMID:21664559

    1954-01-01

    Investigations on infectious diseases of Pacific salmon due to micro-organisms other than viruses are reviewed. The etiological agents include trematodes, fungi, protozoa and bacteria. Bacteria have been found to be the most important agents of disease in the several species of Pacific salmon. Kidney disease, due to a small, unnamed Gram-positive diplobacillus, causes serious mortalities in young salmon reared in hatcheries. The disease has also been found in wild fish. Aquatic myxobacteria are important agents of disease both in the hatchery and in the natural habitat. One of the myxobacteria, Chondrococcus columnaris, causes disease at relatively high water temperatures. The problem of the taxonomy of this organism is discussed. Another myxobacterium, Cytophaga psychrophila, has been found responsible for epizootics in coho salmon at lower water temperatures, i.e., in the range of 40° to 55° F. In outbreaks of gill disease in young salmon, myxobacteria of several kinds have been implicated.

    The current influx of refugees and the high rate of immigration increase the rate and impact of infectious diseases in Europe. Infections can be detected at the initial examination of arriving refugees as a result of systematic screening or within the framework of general medical care. Diagnosis and treatment require special expertise and in some cases special precautions. The spectrum of infections is determined by the country of origin of migrants and the conditions experienced on fleeing to Germany. In this article the diagnostics and treatment of the most important infections are presented. As far as infections are concerned refugees and migrants do not represent a threat to the general population but instead have to be perceived as a highly vulnerable group. PMID:27142435

    Infectious endocarditis remains both a diagnostic and a treatment challenge. A positive outcome depends on a rapid diagnosis, accurate risk stratification, and a thorough follow-up. Imaging plays a key role in each of these steps and echocardiography remains the cornerstone of the methods in use....... The technique of both transthoracic echocardiography and transoesophageal echocardiography has been markedly improved across the last decades and most recently three-dimensional real-time echocardiography has been introduced in the management of endocarditis patients. Echocardiography depicts structural changes...... with conventional CT (SPECT/CT). Of these methods, (18)F-FDG PET-CT carries the best promise for a future role in endocarditis.

    2016-08-01

    Biologic response modifiers (BRMs) are substances that interact with and modify the host immune system. BRMs that dampen the immune system are used to treat conditions such as juvenile idiopathic arthritis, psoriatic arthritis, or inflammatory bowel disease and often in combination with other immunosuppressive agents, such as methotrexate and corticosteroids. Cytokines that are targeted include tumor necrosis factor α; interleukins (ILs) 6, 12, and 23; and the receptors for IL-1α (IL-1A) and IL-1β (IL-1B) as well as other molecules. Although the risk varies with the class of BRM, patients receiving immune-dampening BRMs generally are at increased risk of infection or reactivation with mycobacterial infections (Mycobacterium tuberculosis and nontuberculous mycobacteria), some viral (herpes simplex virus, varicella-zoster virus, Epstein-Barr virus, hepatitis B) and fungal (histoplasmosis, coccidioidomycosis) infections, as well as other opportunistic infections. The use of BRMs warrants careful determination of infectious risk on the basis of history (including exposure, residence, and travel and immunization history) and selected baseline screening test results. Routine immunizations should be given at least 2 weeks (inactivated or subunit vaccines) or 4 weeks (live vaccines) before initiation of BRMs whenever feasible, and inactivated influenza vaccine should be given annually. Inactivated and subunit vaccines should be given when needed while taking BRMs, but live vaccines should be avoided unless under special circumstances in consultation with an infectious diseases specialist. If the patient develops a febrile or serious respiratory illness during BRM therapy, consideration should be given to stopping the BRM while actively searching for and treating possible infectious causes.

  10. Cardiovascular involvement in psoriatic arthritis

    Full Text Available Psoriasis is a chronic, genetically determined and immunomediated inflammatory skin disease that affects 2-3% of the Caucasian population. A considerable proportion of these patients develop a form of inflammatory arthritis known as psoriatic arthritis (PsA, although the prevalence of this has not been well defined. Patients with PsA have a higher mortality rate than the general population and the risk of mortality is related to disease severity at the time of presentation. Endothelial dysfunction and early atherosclerosis have been found in patients with PsA without any cardiovascular disease (CVD risk factors, and experts believe that CVD is one of the leading causes of death, as it is in patients with rheumatoid arthritis (RA. Various disease-related mechanisms may be involved in the development of premature vascular damage in both cases, including an increased synthesis of proinflammatory mediators (such as cytokines, chemokines and adhesion molecules, autoantibodies against endothelial cell components, perturbations in T-cell subsets, genetic polymorphisms, hyperhomocysteinemia, oxidative stress, abnormal vascular repair, and iatrogenic factors. In a recent study of 22 patients with PsA without any signs of CVD, we found that the plasma concentration of asymmetric dimethylarginine (ADMA levels were significantly high and coronary flow reserve (CFR was significantly reduced. Moreover, there was a significant correlation between CFR and plasma ADMA levels in the PsA group. The significant correlation between the reduced CRF and increased ADMA levels suggests that, like patients with early RA, PsA patients suffer from endothelial dysfunction and impaired coronary microcirculation. Active PsA is a risk factor for CVD, and so PsA patients should be screened for subclinical forms of the disease and its risk factors, and an early treatment approach should be adopted.

    Suggestive, but largely unproven, observations have associated arthritis with environmental antigens, including foods. We studied a patient with inflammatory arthritis in a prospective, "blinded," controlled fashion to determine whether her symptoms were associated with food sensitivities. This 52-year-old white woman with 11 years of class I, stage I, active disease, had symptomatic exacerbations allegedly associated with meat, milk, and beans. We observed an increase in symptoms following an unblinded food challenge and then studied her in our clinical research unit. On her normal diet for 6 days, she averaged 30 minutes of morning stiffness, 9 tender joints, 3 swollen joints, 87% subjective assessment (100% = best possible), and 89% examiner assessment. While she was fasting (3 days) or taking Vivonex (2 days), we noted no morning stiffness, tender joint score of 1, swollen joint score of 0, and assessments of 100% (P less than 0.05 versus normal diet). She was then nourished with Vivonex for 33 days without difficulty and challenged in a blinded fashion at mealtimes with lyophilized foods placed into opaque capsules. Four milk challenges (equivalent to greater than or equal to 8 ounces per meal) produced up to 30 minutes of morning stiffness, 14 tender joints, 4 swollen joints, subjective assessment of 85%, and objective assessment of 80% (P less than 0.05 versus fasting-Vivonex), peaking 24-48 hours postchallenge. Placebo and other foods (lettuce and carrots) were without effect.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3513771

    Although the use of corticosteroids in juvenile idiopathic arthritis (JIA) is now much more limited owing to the availability of methotrexate and biological agents, there are clinical scenarios where it is still indicated. For example, corticosteroids may be indicated for intraarticular injections to prevent joint deformities, as a "bridge" drug to relieve symptoms in polyarticular disease while waiting for methotrexate and biologics to exert their full therapeutic effects, and in the treatment of chronic iridocyclitis, macrophage activation syndrome, and systemic JIA, although the advent of interleukin (IL)-1 and IL-6 blockers has greatly reduced the latter indication.

    Full Text Available Psoriatic arthritis is a complex disease affecting primarily peripheral and axial joints and entheses together with the skin. The pathogenesis is characterized by a genetic background and by inflammatory mechanisms which may be triggered by environmental factors. Several susceptibility genes have been investigated; they include HLA genes, genes within the HLA region and genes outside the HLA region. T cells, including the recently described subset Th17, are thought to play an important role in the acute and chronic phases of the disease. Some of these findings allowed novel therapeutic interventions or opened new promising approaches in treatment. The most relevant data of the literature are summarized and discussed.

Depending on the severity of the disease and the clinical picture, physiotherapy, ergotherapy, hydrotherapy and heat treatment, as well as massage and electrotherapy may all be considered. When properly applied, these treatments have the advantage of being free of side effects. Scientific proof of effectiveness is often lacking in physical medicine, which clearly represents a challenge to the discipline in the years to come. PMID:2182487

    Differential diagnosis between spinal metastasis and infectious spondylodiscitis is one of the occasional challenges in daily clinical practice. We encountered an unusual case of spinal metastasis in a 75-year-old female breast cancer patient that mimicked infectious spondylodiscitis. Magnetic resonance imaging (MRI) showed diffuse bone marrow infiltrations with paraspinal soft tissue infiltrative changes in 5 contiguous cervical vertebrae without significant compression fracture or cortical destruction. These MRI findings made it difficult to differentiate between spinal metastasis and infectious spondylodiscitis. Infectious spondylodiscitis such as tuberculous spondylodiscitis was regarded as the more appropriate diagnosis due to the continuous involvement of > 5 cervical vertebrae. The patient's clinical presentation also supported the presumptive diagnosis of infectious spondylodiscitis rather than spinal metastasis. Intravenous antibiotics were administered, but clinical symptoms worsened despite treatment. After pathologic confirmation by computed tomography-guided biopsy, we were able to confirm a final diagnosis of spinal metastasis.

    Rheumatoid arthritis is a heterogeneous disease with clinical and biological polymorphisms. IL-1RN is a protein that binds to interleukin-1 (IL-1) receptors and inhibits the binding of IL-1-alpha and IL-1-beta. IL-1RN levels are elevated in the blood of patients with a variety of infectious, immune, and traumatic conditions. Balb/c mice deficient in IL-1ra (mouse gene of IL-1RN) develop spontaneous autoimmune arthritis while DBA/1 mice deficient in IL-1ra do not. Previously, we identified a major QTL that regulates the susceptibility to arthritis in Balb/c mice with IL-1ra deficiency. In this study, we found that the QTL may contain two peaks that are regulated by two sets of candidate genes. By haplotype analysis, the total genomic regions of candidate genes were reduced from about 19 Mbp to approximately 9 Mbp. The total number of candidate genes was reduced from 208 to 21.

  5. Radiographic manifestations of arthritis in AIDS patients

    International Nuclear Information System (INIS)

    The purpose of this study is to familiarize the radiologist with a newly discovered association between arthritis and acquired immunodeficiency syndrome (AIDS). The authors retrospectively reviewed the clinical and radiographic findings in 31 patients with human immunodeficiency virus (HIV) infection referred to their rheumatology clinic with musculoskeletal complaints. The patients carried a wide range of clinical diagnosis including Reiter syndrome, psoriatic arthritis, undifferentiated seronegative arthritis, isolated enthesopathies, rheumatoid arthritis and osteonecrosis. Radiographs were available in 24 of the 31 patients, and in 20 they showed radiographic features of arthritis, which included soft-tissue swelling periarticular osteoporosis, synovial effusions, sacroiliitis, periosteal reaction, joint space narrowing, marginal erosions, and osteonecrosis. Although the radiographic abnormalities were frequently mild, they were significant, given the short duration of disease in many of their patients (weeks to months) at the time radiographs were obtained. The range of radiographic findings in their series was varied and paralleled the wide range of clinical diagnoses. No findings were pathognomonic for HIV-associated arthritis. Nevertheless, HIV infection needs to be considered in any patient belonging to a recognized risk group who presents with musculoskeletal disease. This is particularly important since immunosupressive drugs used for the treatment of arthritis can be detrimental to patients with HIV infection

  6. Inhibition of inflammatory arthritis using fullerene nanomaterials.

    Directory of Open Access Journals (Sweden)

    Anthony L Dellinger

    Full Text Available Inflammatory arthritis (e.g. rheumatoid arthritis; RA is a complex disease driven by the interplay of multiple cellular lineages. Fullerene derivatives have previously been shown to have anti-inflammatory capabilities mediated, in part, by their ability to prevent inflammatory mediator release by mast cells (MC. Recognizing that MC can serve as a cellular link between autoantibodies, soluble mediators, and other effector populations in inflammatory arthritis, it was hypothesized that fullerene derivatives might be used to target this inflammatory disease. A panel of fullerene derivatives was tested for their ability to affect the function of human skin-derived MC as well as other lineages implicated in arthritis, synovial fibroblasts and osteoclasts. It is shown that certain fullerene derivatives blocked FcγR- and TNF-α-induced mediator release from MC; TNF-α-induced mediator release from RA synovial fibroblasts; and maturation of human osteoclasts. MC inhibition by fullerene derivatives was mediated through the reduction of mitochondrial membrane potential and FcγR-mediated increases in cellular reactive oxygen species and NF-κB activation. Based on these in vitro data, two fullerene derivatives (ALM and TGA were selected for in vivo studies using K/BxN serum transfer arthritis in C57BL/6 mice and collagen-induced arthritis (CIA in DBA/1 mice. Dye-conjugated fullerenes confirmed localization to affected joints in arthritic animals but not in healthy controls. In the K/BxN moldel, fullerenes attenuated arthritis, an effect accompanied by reduced histologic inflammation, cartilage/bone erosion, and serum levels of TNF-α. Fullerenes remained capable of attenuating K/BxN arthritis in mast cell-deficient mice Cre-Master mice, suggesting that lineages beyond the MC represent relevant targets in this system. These studies suggest that fullerene derivatives may hold promise both as an assessment tool and as anti-inflammatory therapy of arthritis.

  7. Complementary medicine in rheumatoid arthritis

    Full Text Available Use of complementary and alternative medicine (CAM for chronic conditions has increased in recent years. CAM is immensely popular for musculoskeletal conditions and patients suffering from rheumatoid arthritis (RA frequently try CAM. This review summarises the trial data for or against CAM as a symptomatic treatment for rheumatoid arthritis. Collectively the evidence demonstrates that some CAM modalities show significant promise, e.g. acupuncture, diets, herbal medicine, homoeopathy, massage, supplements. However, for the great majority of these therapies no evidencebased (clinical randomized trials results are available. CAM is usually used in addition to, and not as a substitute for conventional therapies. The motivation of patients to try CAM is complex; the willingness to take control of their healthcare, the desire to try everything available, the mass-media pressure and the erroneous notion that CAM is without risks. In fact, none of these treatments is totally devoid of risks. While the use of complementary and alternative modalities for the treatment of RA continues to increase, rigorous clinical trials examining their efficacy are needed before definitive recommendations regarding the application of these modalities can be made.

    Over the past 10 years, the management of rheumatoid arthritis has been revolutionized. Early diagnosis is essential and should allow an early initiation of disease modifying anti-rheumatic drugs (DMARD), if possible within the first 3 three months after disease onset, aiming at disease remission and the best long-term prognosis. Recommendations for the prescription of synthetic and biologic DMARD (mainly anti-TNFalpha agents) are available since September 2007 [6] by HAS in France. The great efficacy of these drugs has been established from many clinical trials including tens of thousands of patients. However, severe adverse side effects may occur (allergy, tuberculosis, opportunistic infections, demyelination) and rheumatologists should remain vigilant. Global care of the patient includes prescription of pharmacologic and non-pharmacologic treatments (education, physical treatment, ergotherapy, psychotherapy, surgery). A good coordination between all specialists is required. Screening and treatment of extra-articular manifestations, prevention of infections, osteoporosis and cardiovascular complications are essential to allow a better long-term prognosis, and reduce disability and mortality of rheumatoid arthritis.

Material and methods. 46 pts with definite rheumatoid arthritis were examined at the time of comorbid infection (Cl detection and after infection focus sanation. Bacteriological test with evaluation of flora sensitivity to antibiotics by disco-diffusion method was performed at baseline and after the course of antibacterial therapy to assess its efficacy. Hemogram, serum fibrinogen, rheumatoid factor, circulating immune complexes (CIC, C-reactive protein levels were assessed. Serum interleukin (IL 1(3, IL6 and neopterin concentrations were examined by immune-enzyme assay in a part of pts. Typical clinical features of Cl were present in only 28 (60,9% pts. 13 (28,3% pts had fever, 12 (26,0% — leukocytosis, 15 (32,6% — changes of leucocyte populations. Some laboratory measures (thrombocytes, fibrinogen, CIC, neopterin levels significantly decreased (p<0,05 after infection focus sanation without correction of disease modifying therapy. Cl quite often develop as asymptomatic processes most often in pts with high activity and can induce disturbances promoting appearance of endothelial dysfunction, atherothrombosis and reduction of life duration. So timely detection and proper sanation of infection focuses should be performed in pts with RA

    It is estimated that in Poland about 400,000 persons in general suffer from inflammatory joint diseases, including rheumatoid arthritis (RA). Epidemiological surveys documenting the frequency and disturbance of musculoskeletal disorders in the Polish population are few in number. Most of the estimations are based on epidemiological data from other countries (prevalence of 0.5-1%). According to the data of the National Health Fund in Poland 135,000-157,000 persons in total are treated because of rheumatoid arthritis per year [ICD10 (International Statistical Classification of Diseases and Related Health Problems): M05, M06]. In the case of this group of diseases indirect costs significantly outweigh the direct costs. Indirect costs increase together with activity level of the disease. The cost analysis of productivity loss of RA patients indicates that sickness absenteeism and informal care are the most burdensome. At the national level it amounts in total from 1.2 billion to 2.8 billion PLN per year, depending on the method of analysis. These costs could be significantly reduced through early diagnosis and introduction of effective treatment.

    A case of Lyme arthritis with advanced degenerative changes localized to the midcarpal joint was treated with a limited wrist arthrodesis with relief of pain and improved function. Chronic Lyme arthritis occurs as the third stage of Lyme disease. Serologic testing and a history of a characteristic rash may be helpful in the diagnosis. Radiographic and histopathologic findings are nonspecific, with both degenerative and inflammatory characteristics. Intravenous antibiotics provide an effective treatment of chronic Lyme arthritis.

    Still's disease (Systemic-onset Juvenile Idiopathic Arthritis: SoJIA) is characterised by high-spiking daily fevers, arthritis and evanescent rashes. Diagnosis of Still's disease is often challenging. Infectious diseases and other inflammatory conditions, especially in young children, Kawasaki disease may look similar. Clinicians often rely on echocardiographic evidence of coronary artery abnormalities to differentiate between Kawasaki disease and Still's disease. Coronary artery dilation would typically favour the diagnosis of Kawasaki disease. We present four children with Still's disease and coronary artery abnormalities who were initially misdiagnosed as Kawasaki disease. The first patient had pericarditis and an irregular wall of the left coronary artery, without dilation on echocardiography. The second patient had a left coronary artery dilatation and a pericarditis. The third patient had thickened left coronary artery walls, and the fourth patient had a hyperechogenicity of the left and right coronary arteries. They received IVIG without success. The diagnosis of Still's disease was made secondary with evidence of persistent arthritis. All but one patient finally needed biologic treatments. Coronary abnormalities may be observed during various febrile conditions and do not exclude the diagnosis of Still's disease.

    Full Text Available Arthritides are acute or chronic inflammation of one or more joints. The most common types of arthritis are osteoarthritis and rheumatoid arthritis, but there are more than 100 different forms. Right and early diagnosis is extremely important for the prevention of eventual structural and functional disability of the affected joint. Imaging findings, especially those of advanced level imaging, play a major role in diagnosis and monitor the progression of arthritis or its response to therapy. The objective of the review is to discuss the findings of conventional and advanced radiological imaging of most common arthritides and to present a simplified approach for their radiological evaluation.

  17. A Comparative Metabolomic Evaluation of Behcet's Disease with Arthritis and Seronegative Arthritis Using Synovial Fluid.

    Directory of Open Access Journals (Sweden)

    Joong Kyong Ahn

    Full Text Available Behcet's disease (BD with arthritis is often confused with seronegative arthritis (SNA because of shared clinical symptoms and the lack of definitive biomarkers for BD. To investigate possible metabolic patterns and potential biomarkers of BD with arthritis, metabolomic profiling of synovial fluid (SF from 6 patients with BD with arthritis and 18 patients with SNA was performed using gas chromatography/time-of-flight mass spectrometry in conjunction with univariate and multivariate statistical analyses. A total of 123 metabolites were identified from samples. Orthogonal partial least square-discriminant analysis showed clear discrimination between BD with arthritis and SNA. A set of 11 metabolites were identified as potential biomarkers for BD using variable importance for projection values and the Wilcoxon-Mann-Whitney test. Compared with SNA, BD with arthritis exhibited relatively high levels of glutamate, valine, citramalate, leucine, methionine sulfoxide, glycerate, phosphate, lysine, isoleucine, urea, and citrulline. There were two markers identified, elevated methionine sulfoxide and citrulline, that were associated with increased oxidative stress, providing a potential link to BD-associated neutrophil hyperactivity. Glutamate, citramalate, and valine were selected and validated as putative biomarkers for BD with arthritis (sensitivity, 100%; specificity, 61.1%. This is the first report to present potential biomarkers from SF for discriminating BD with arthritis from SNA. The metabolomics of SF may be helpful in searching for potential biomarkers and elucidating the clinicopathogenesis of BD with arthritis.

    2012-09-01

    Incidence of infection time-series data for the childhood diseases measles, chicken pox, rubella and whooping cough are described in the language of multifractals. We explore the potential of using the wavelet transform maximum modulus (WTMM) method to characterize the multiscale structure of the observed time series and of simulated data generated by the stochastic susceptible-exposed-infectious-recovered (SEIR) epidemic model. The singularity spectra of the observed time series suggest that each disease is characterized by a unique multifractal signature, which distinguishes that particular disease from the others. The wavelet scaling functions confirm that the time series of measles, rubella and whooping cough are clearly multifractal, while chicken pox has a more monofractal structure in time. The stochastic SEIR epidemic model is unable to reproduce the qualitative singularity structure of the reported incidence data: it is too smooth and does not appear to have a multifractal singularity structure. The precise reasons for the failure of the SEIR epidemic model to reproduce the correct multiscale structure of the reported incidence data remain unclear. PMID:22442094

  19. Antibiotic associated diarrhoea: Infectious causes

    Ayyagari A

    2003-01-01

    Full Text Available Nearly 25% of antibiotic associated diarrhoeas (AAD is caused by Clostridium difficile, making it the commonest identified and treatable pathogen. Other pathogens implicated infrequently include Clostridium perfringens, Staphylococcus aureus, Klebsiella oxytoca, Candida spp. and Salmonella spp. Most mild cases of AAD are due to non-infectious causes which include reduced break down of primary bile acids and decrease metabolism of carbohydrates, allergic or toxic effects of antibiotic on intestinal mucosa and pharmacological effect on gut motility. The antibiotics most frequently associated with C. difficile associated diarrhoea are clindamycin, cephalosporin, ampicillin and amoxicillin. Clinical presentation may vary from mild diarrhoea to severe colitis and pseudomembranous colitis associated with high morbidity and mortality. The most sensitive and specific diagnostic test for C. difficile infection is tissue culture assay for cytotoxicity of toxin B. Commercial ELISA kits are available. Though less sensitive, they are easy to perform and are rapid. Withdrawal of precipitating antibiotic is all that is needed for control of mild to moderate cases. For severe cases of AAD, oral metronidazole is the first line of treatment, and oral vancomycin is the second choice. Probiotics have been used for recurrent cases.

    Arthritis mutilans is often described as the most severe form of psoriatic arthritis. However, a widely agreed on definition of the disease has not been developed. At the 2012 annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA), members hoped to agree on a definition of arthritis mutilans and thus facilitate clinical and molecular epidemiological research into the disease. Members discussed the clinical features of arthritis mutilans and definitions used by researchers to date; reviewed data from the ClASsification for Psoriatic ARthritis study, the Nordic psoriatic arthritis mutilans study, and the results of a premeeting survey; and participated in breakout group discussions. Through this exercise, GRAPPA members developed a broad consensus on the features of arthritis mutilans, which will help us develop a GRAPPA-endorsed definition of arthritis mutilans. PMID:23908536

    Little information is available about several important aspects of the treatment of melioidosis osteomyelitis and septic arthritis. We undertook a retrospective review of 50 patients with these conditions in an attempt to determine the effect of location of the disease, type of surgical intervention and duration of antibiotic treatment on outcome, particularly complications and relapse. We found that there was a 27.5% risk of osteomyelitis of the adjacent bone in patients with septic arthritis in the lower limb. Patients with septic arthritis and osteomyelitis of an adjacent bone were in hospital significantly longer (p = 0.001), needed more operations (p = 0.031) and had a significantly higher rate of complications and re-presentation (p = 0.048). More than half the patients (61%), most particularly those with multifocal bone and joint involvement, and those with septic arthritis and osteomyelitis of an adjacent bone who were treated operatively, needed more visits to theatre.

    Synovial fluid, ultrasound, and radiographic imaging are common diagnostic tools for septic arthritis. Mycoplasma septic arthritis is suspected in calves with clinical signs of otitis and pneumonia. Commonly affected joints are carpus, stifle, and tarsus. Treatment strategy must include long-term antibiotics, anti-inflammatories, and joint lavage. Knowledge of communication and boundaries for commonly affected joints is essential to perform joint lavage and arthrotomy.

    Twenty-six patients with a pauciarticular arthritis have been studied clinically, radiologically and with histocompatibility typing. An increased frequency of HLA B27 was found (p = 1.87 x 10(-12)). Low back and buttock pain, Achilles tendinitis and dactylitis of the toes were more frequent in HLA-B27 positive patients. It is suggested that histocompatibility testing may be of some value in diagnosis and in the investigation of the possible 'reactive' nature of this type of arthritis.

    Control of disease activity and recovery of function are major issues in the treatment of children and adolescents suffering from juvenile idiopathic arthritis (JIA). Functional therapies including physiotherapy are important components in the multidisciplinary teamwork and each phase of the disease requires different strategies. While in the active phase of the disease pain alleviation is the main focus, the inactive phase requires strategies for improving motility and function. During remission the aim is to regain general fitness by sports activities. These phase adapted strategies must be individually designed and usually require a combination of different measures including physiotherapy, occupational therapy, massage as well as other physical procedures and sport therapy. There are only few controlled studies investigating the effectiveness of physical therapies in JIA and many strategies are derived from long-standing experience. New results from physiology and sport sciences have contributed to the development in recent years. This report summarizes the basics and main strategies of physical therapy in JIA.

    Full Text Available Rheumatoid arthritis (RA is a chronic, systemic, autoimmune inflammatory disorder that is characterized by joint inflammation, erosive properties and symmetric multiple joint involvement. Temporomandibular joint (TMJ is very rare to be affected in the early phase of the disease, thus posing diagnostic challenges for the dentist. Conventional radiographs fail to show the early lesions due to its limitations. More recently cone-beam computed tomography (CBCT has been found to diagnose the early degenerative changes of TMJ and hence aid in the diagnosis of the lesions more accurately. Our case highlights the involvement of TMJ in RA and the role of advanced imaging (CBCT in diagnosing the bony changes in the early phase of the disease.

    The main objectives of team management of rheumatoid arthritis are to stop structural damage of joints and to reduce functional, psychological, socioprofessional and economic consequences. Team management requires the collaboration, around the patient, of a rheumatologist, a nurse, a psychologist, a physiotherapist, an occupational therapist, an orthopaedic surgeon at the same time, in the same place. More and more patients wish to manage their disease by themselves. Team care should not be proposed to every patient; it must be reserved to patients whose condition required such an approach because of the severity of the disease, comorbidity, psychological or socioprofessionnal difficulties. Team management should be personalized. Utility of team management is now accepted; out-patient administration is as effective as in-patient one. A good educational program is very important. However, search is still needed to define optimal modalities of team management and tools to measure the efficiency of this approach.

    Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by destructive cartilages, bones and other structures formed joints. RA belongs to connective tissue diseases represented by systemic nature, internal illness, extra-articular features and rapidly progress of atherosceirosis. The extra-articular complications cause the reduction of patient longevity. The frequency of symptoms in patient with RA and respiratory disorders occur in 10-20% of cases. Pulmonary complications are the second most common cause of premature of patient deaths. Respiratory disorders associated with RA are devided into 3 groups: infection, lung disease caused by drugs and pulmonary manifestation connected by RA. These last affect interstitial tissue, bronchioli, pulmonary vessels, pleura, also are presented by pulmonary rheumatoid nodules and pulmonary hypertension.

    Psoriasis is an immune-mediated skin disease which affects 2-4% of the worldwide population. Approximately 20-30% of patients with psoriasis develop psoriatic arthritis (PsA), a frequently destructive and disabling condition. As skin manifestations precede joint symptoms in nearly all patients with PsA, identification of biomarkers for early prediction of joint damage is an important clinical need. Because not all patients with PsA respond to treatment in the same fashion, identification of biomarkers capable of predicting therapeutic response is also imperative. Here, we review existing literature and discuss current investigations to identify potential biomarkers for PsA disease activity, with particular emphasis on microRNAs as novel markers of interest. Serum (soluble) biomarkers, peripheral osteoclast precursor as cellular biomarkers, and genetic loci associated with skin and joint disease are also reviewed. PMID:26602058

    Full Text Available The most common form of chronic arthritis is osteoarthritis (OA with prevalence as high as 80% after age 75 (Arden and Nevitt, 2006. The incidence of OA is expected to increase as the population ages, increasing the socioeconomic burden of OA. Despite the signifi cant burden of this disease, no drug has been identifi ed that can effectively modify disease progression (Moskowitz and Hooper, 2005; Abadie et al. 2004. However, slowing disease progress and improvement in quality of life may be achieved by behavioral modifi cations, such as weight loss and exercise. Many patients with early OA will progress to disability and joint replacement. Physical examination and radiographic studies are relatively poor means for detecting disease early or predicting progression. Therefore, identifi cation of factors to facilitate early OA diagnosis and prognosis is a major focus of current OA research (Lohmander and Felson, 2004; Lohmander, 2004; Garnero and Delmas, 2003.

    One of the important pursuits in science and engineering research today is to develop low-cost and user-friendly technologies to improve the health of people. Over the past decade, research efforts in microfluidics have been made to develop methods that can facilitate low-cost diagnosis of infectious diseases, especially in resource-poor settings. Here, we provide an overview of the recent advances in microfluidic devices for point-of-care (POC) diagnostics for infectious diseases and emphasis is placed on malaria, sepsis and AIDS/HIV. Other infectious diseases such as SARS, tuberculosis, and dengue are also briefly discussed. These infectious diseases are chosen as they contribute the most to disability-adjusted life-years (DALYs) lost according to the World Health Organization (WHO). The current state of research in this area is evaluated and projection toward future applications and accompanying challenges are also discussed. PMID:26854743

  4. Global Climate Change and Infectious Diseases

    Full Text Available Climate change is occurring as a result of warming of the earth’s atmosphere due to human activity generating excess amounts of greenhouse gases. Because of its potential impact on the hydrologic cycle and severe weather events, climate change is expected to have an enormous effect on human health, including on the burden and distribution of many infectious diseases. The infectious diseases that will be most affected by climate change include those that are spread by insect vectors and by contaminated water. The burden of adverse health effects due to these infectious diseases will fall primarily on developing countries, while it is the developed countries that are primarily responsible for climate change. It is up to governments and individuals to take the lead in halting climate change, and we must increase our understanding of the ecology of infectious diseases in order to protect vulnerable populations.

    Full Text Available Over the past decade in Canada, infectious disease outbreaks have repeatedly been in the public spotlight. The Escherichia coli outbreak in Walkerton, Ontario (1, the severe acute respiratory syndrome outbreak in Toronto, Ontario (2 and the Clostridium difficile hospital outbreak in Montreal, Quebec (3, have cost lives, grabbed headlines and stressed local health care systems. Each outbreak raised questions about our ability to prevent outbreaks, detect outbreaks early, and respond efficiently and effectively to infectious disease crises; these outbreaks also highlighted gaps in Canada's preparedness for managing major infectious disease problems when multiple jurisdictions are involved (4. Canada's poor track record of tuberculosis control in the north (5 raises the concern that this problem is not limited to crisis situations, but rather has deeper implications for the management of infectious diseases in Canada.

    BACKGROUND: Present understanding of increased risk of Epstein-Barr virus (EBV)-related infectious mononucleosis among children of low birth order or small sibships is mainly based on old and indirect evidence. Societal changes and methodological limitations of previous studies call for new data...... of blood donors followed up retrospectively for self-reported infectious mononucleosis. CONCLUSIONS: Younger siblings, and to a lesser degree older siblings, seem to be important in the transmission of EBV within families. Apparently the dogma of low birth order in a sibship as being at the highest risk...... sibship structure into account. RESULTS: A total of 12,872 cases of infectious mononucleosis were observed during 35.3 million person-years of follow-up. Statistical modelling showed that increasing sibship size was associated with a reduced risk of infectious mononucleosis and that younger siblings...

Proper clinical diagnosis of any of these infectious conditions is based on epidemiological data, history, systemic symptoms and signs, and the pattern of ocular findings. Diagnosis is confirmed by serologic testing and polymerase chain reaction in selected cases. Treatment of infectious optic neuropathies involves the use of specific anti-infectious drugs and corticosteroids to suppress the associated inflammatory reaction. The visual prognosis is generally good, but persistent severe vision loss with optic atrophy can occur.

    Full Text Available To determine the rate of different types of arthritis in children. We prepared a retrospective descriptive study and included the whole 100 cases of arthritis referred to 17-Shahrivar Hospital, Rasht, Guilan during a 3 years period. Using their medical files, data including age, sex, season of admission, history of trauma, signs and symptoms, lab findings and duration of hospitalization were collected. SPSS 13.0 (statistical software applied for statistical analysis. The most common age of involvement ranged 6-9 years. Septic arthritis, brucellosis, and rheumatoid fever were the most frequent causes of arthritis in our study. Fever and restricted range of motion had the highest rate among different signs and symptoms. Lab data demonstrated leukocytosis, positive CRP, and increased ESR among 74, 79.5, and 73 percent of our patients, respectively. According to the high prevalence of septic arthritis and the arthritis due to brucellosis and rheumatoid fever, it seems that mentioned diseases are still major problems in the issue of hygiene management.

  13. Burden of childhood-onset arthritis

    Full Text Available Abstract Juvenile arthritis comprises a variety of chronic inflammatory diseases causing erosive arthritis in children, often progressing to disability. These children experience functional impairment due to joint and back pain, heel pain, swelling of joints and morning stiffness, contractures, pain, and anterior uveitis leading to blindness. As children who have juvenile arthritis reach adulthood, they face possible continuing disease activity, medication-associated morbidity, and life-long disability and risk for emotional and social dysfunction. In this article we will review the burden of juvenile arthritis for the patient and society and focus on the following areas: patient disability; visual outcome; other medical complications; physical activity; impact on HRQOL; emotional impact; pain and coping; ambulatory visits, hospitalizations and mortality; economic impact; burden on caregivers; transition issues; educational occupational outcomes, and sexuality. The extent of impact on the various aspects of the patients', families' and society's functioning is clear from the existing literature. Juvenile arthritis imposes a significant burden on different spheres of the patients', caregivers' and family's life. In addition, it imposes a societal burden of significant health care costs and utilization. Juvenile arthritis affects health-related quality of life, physical function and visual outcome of children and impacts functioning in school and home. Effective, well-designed and appropriately tailored interventions are required to improve transitioning to adult care, encourage future vocation/occupation, enhance school function and minimize burden on costs.

    2015-01-01

    Full Text Available Objectives. Physiologic and immunologic changes in pregnancy result in increased susceptibility to infection. These shifts are more pronounced in pregnancies complicated by multiple gestation. The objective of this study was to determine the association between multiple gestation and risk of infectious morbidity. Study Design. The Nationwide Inpatient Sample for the years 2008–2010 was used to identify pregnant women during admission for delivery with International Classification of Diseases codes. Logistic regression was used to compute odds ratios and 95% confidence intervals for demographic data, preexisting medical conditions, and acute medical and infectious complications for women with multiple versus singleton gestations. Results. Among women with multiple gestation, 38.4 per 1,000 women had an infectious complication compared to 12.8 per 1,000 women with singletons. The most significant infectious morbidity associated with multiple gestation was intestinal infections, pyelonephritis, influenza, and pneumonia. After controlling for confounding variables, infectious complications at delivery persisted for women with multiples, though the association was dependent on mode of delivery. Conclusions. Women with multiple gestations are at increased risk for infectious morbidity identified at the time of delivery. This association was diminished among women who had a cesarean suggesting that operative delivery is not responsible for this association.

    The distributions of most infectious agents causing disease in humans are poorly resolved or unknown. However, poorly known and unknown agents contribute to the global burden of disease and will underlie many future disease risks. Existing patterns of infectious disease co-occurrence could thus play a critical role in resolving or anticipating current and future disease threats. We analyzed the global occurrence patterns of 187 human infectious diseases across 225 countries and seven epidemiological classes (human-specific, zoonotic, vector-borne, non-vector-borne, bacterial, viral, and parasitic) to show that human infectious diseases exhibit distinct spatial grouping patterns at a global scale. We demonstrate, using outbreaks of Ebola virus as a test case, that this spatial structuring provides an untapped source of prior information that could be used to tighten the focus of a range of health-related research and management activities at early stages or in data-poor settings, including disease surveillance, outbreak responses, or optimizing pathogen discovery. In examining the correlates of these spatial patterns, among a range of geographic, epidemiological, environmental, and social factors, mammalian biodiversity was the strongest predictor of infectious disease co-occurrence overall and for six of the seven disease classes examined, giving rise to a striking congruence between global pathogeographic and "Wallacean" zoogeographic patterns. This clear biogeographic signal suggests that infectious disease assemblages remain fundamentally constrained in their distributions by ecological barriers to dispersal or establishment, despite the homogenizing forces of globalization. Pathogeography thus provides an overarching context in which other factors promoting infectious disease emergence and spread are set.

  15. Juvenile rheumatoid arthritis: therapeutic perspectives.

    Science.gov (United States)

    Chikanza, Ian C

    2002-01-01

    Juvenile rheumatoid arthritis (JRA) is the most common childhood chronic systemic autoimmune inflammatory disease. The therapeutic approach to JRA has, to date, been casual and based on extensions of clinical experiences gained in the management of adult rheumatoid arthritis (RA). The physiology of inflammation has been systemically studied and this has led to the identification of specific therapeutic targets and the development of novel approaches to the management of JRA. The classical treatments of the disease such as methotrexate, sodium aurothiomalate and sulfasalazine, are not always effective in controlling RA and JRA. This has necessitated the development of novel agents for treating RA, most of which are biological in nature and are targeted at specific sites of the inflammatory cascades. These biological therapeutic strategies in RA have proved successful and are being applied in the management of JRA. These developments have been facilitated by the advances in molecular biology which have heralded the advent of biodrugs (recombinant proteins) and gene therapy, in which specific genes can be introduced locally to enhance in vivo gene expression or suppress gene(s) of interest with a view to down-regulating inflammation. Some of these biodrugs, such as anti-tumor necrosis factor alpha (anti-TNFalpha), monoclonal antibodies (infliximab, adalimumab), TNF soluble receptor constructs (etanercept) and interleukin-1 receptor antagonist (IL-1Ra) have been tested and shown to be effective in RA. Etanercept has now been licensed for JRA. Clinical trials of infliximab in JRA are planned. Studies show that the clinical effects are transient, necessitating repeated treatments and the risk of vaccination effects. Anti-inflammatory cytokines such as IL-4, IL-10, transforming growth factor-beta and interferon-beta (IFN-beta) are undergoing clinical trials. Many of these agents have to be administered parenterally and production costs are very high; thus, there is a need

  1. Health systems perspectives - infectious diseases of poverty.

    Science.gov (United States)

    Huntington, Dale

    2012-01-01

    The right to health as a fundamental human right is enshrined in the World Health Organization's charter and has been reaffirmed in international agreements spanning decades. This new journal reminds us of the essential characteristic of poverty as a violent abuse of human rights. The context of poverty - its social, political and economic dimensions - remain in the reader's mind as evidence is provided on technical solutions to managing the infectious diseases that afflict poor populations world-wide. Applying a health systems framework to a discussion on infectious diseases of poverty emerges from the papers in this journal's first edition. Many of the articles discuss treatments, indicating the importance of pharmaceuticals for neglected diseases. Delivery strategies to reach impoverished populations also figure within this first round of papers. Innovative programs that provide diagnostics and treatment for infectious diseases to hard-to-reach rural and urban communities are needed clearly needed, and some good examples are discussed here. Future editions will explore other health system components, broadening the evidence base to increase understanding of effective and sustainable interventions to reduce the burden of infectious disease among the poor. The editors are to be congratulated on the release of this inaugural issue of the journal Infectious Diseases of Poverty. We look forward to reading subsequent editions. PMID:23848993

    2009-01-01

    An efficient electronic management system is now an essential tool for the successful management and monitoring of those affected by communicable infectious diseases (Human Immunodeficiency Virus - HIV, hepatitis C - HEP C) during the course of the treatment. The current methods which depend heavily on manual collecting, compiling and disseminating treatment information are labor-intensive and time consuming. Clinics specialized in the treatment of infectious diseases use a mix of electronic systems that fail to interact with each other, result in data duplication, and do not support treatment of the patient as a whole. The purpose of the Infectious Disease Management System is to reduce the administrative overhead associated with data collection and analysis while providing correlation abilities and decision support in accordance with defined treatment guidelines. This Infectious Disease Management System was developed to: Ensure cost effectiveness by means of low software licensing costs, Introduce a centralized mechanism of collecting and monitoring all infectious disease management data, Automate electronic retrieval of laboratory findings, Introduce a decision support mechanism as per treatment guidelines, Seamlessly integrate of application modules, Provide comprehensive reporting capabilities, Maintain a high level of user friendliness.

  3. Does biodiversity protect humans against infectious disease?

    Wood, Chelsea L; Lafferty, Kevin D; DeLeo, Giulio; Young, Hillary S; Hudson, Peter J; Kuris, Armand M

    2014-04-01

    Control of human infectious disease has been promoted as a valuable ecosystem service arising from the conservation of biodiversity. There are two commonly discussed mechanisms by which biodiversity loss could increase rates of infectious disease in a landscape. First, loss of competitors or predators could facilitate an increase in the abundance of competent reservoir hosts. Second, biodiversity loss could disproportionately affect non-competent, or less competent reservoir hosts, which would otherwise interfere with pathogen transmission to human populations by, for example, wasting the bites of infected vectors. A negative association between biodiversity and disease risk, sometimes called the "dilution effect hypothesis," has been supported for a few disease agents, suggests an exciting win-win outcome for the environment and society, and has become a pervasive topic in the disease ecology literature. Case studies have been assembled to argue that the dilution effect is general across disease agents. Less touted are examples in which elevated biodiversity does not affect or increases infectious disease risk for pathogens of public health concern. In order to assess the likely generality of the dilution effect, we review the association between biodiversity and public health across a broad variety of human disease agents. Overall, we hypothesize that conditions for the dilution effect are unlikely to be met for most important diseases of humans. Biodiversity probably has little net effect on most human infectious diseases but, when it does have an effect, observation and basic logic suggest that biodiversity will be more likely to increase than to decrease infectious disease risk.

  4. Global Dynamics of Infectious Disease with Arbitrary Distributed Infectious Period on Complex Networks

    Full Text Available Most of the current epidemic models assume that the infectious period follows an exponential distribution. However, due to individual heterogeneity and epidemic diversity, these models fail to describe the distribution of infectious periods precisely. We establish a SIS epidemic model with multistaged progression of infectious periods on complex networks, which can be used to characterize arbitrary distributions of infectious periods of the individuals. By using mathematical analysis, the basic reproduction number R0 for the model is derived. We verify that the R0 depends on the average distributions of infection periods for different types of infective individuals, which extend the general theory obtained from the single infectious period epidemic models. It is proved that if R0<1, then the disease-free equilibrium is globally asymptotically stable; otherwise the unique endemic equilibrium exists such that it is globally asymptotically attractive. Finally numerical simulations hold for the validity of our theoretical results is given.

    Behcet's disease (BD) with arthritis is often confused with seronegative arthritis (SNA) because of shared clinical symptoms and the lack of definitive biomarkers for BD. To investigate possible metabolic patterns and potential biomarkers of BD with arthritis, metabolomic profiling of synovial fluid (SF) from 6 patients with BD with arthritis and 18 patients with SNA was performed using gas chromatography/time-of-flight mass spectrometry in conjunction with univariate and multivariate statist...

    Background To facilitate the development of therapies for rheumatoid arthritis (RA), the Innovative Medicines Initiative BTCure has combined the experience from several laboratories worldwide to establish a series of protocols for different animal models of arthritis that reflect the pathogenesis of RA. Here, we describe chronic pristane-induced arthritis (PIA) model in DA rats, and provide detailed instructions to set up and evaluate the model and for reporting data. Methods We optimized dose of pristane and immunization procedures and determined the effect of age, gender, and housing conditions. We further assessed cage-effects, reproducibility, and frequency of chronic arthritis, disease markers, and efficacy of standard and novel therapies. Results Out of 271 rats, 99.6% developed arthritis after pristane-administration. Mean values for day of onset, day of maximum arthritis severity and maximum clinical scores were 11.8±2.0 days, 20.3±5.1 days and 34.2±11 points on a 60-point scale, respectively. The mean frequency of chronic arthritis was 86% but approached 100% in long-term experiments over 110 days. Pristane was arthritogenic even at 5 microliters dose but needed to be administrated intradermally to induce robust disease with minimal variation. The development of arthritis was age-dependent but independent of gender and whether the rats were housed in conventional or barrier facilities. PIA correlated well with weight loss and acute phase reactants, and was ameliorated by etanercept, dexamethasone, cyclosporine A and fingolimod treatment. Conclusions PIA has high incidence and excellent reproducibility. The chronic relapsing-remitting disease and limited systemic manifestations make it more suitable than adjuvant arthritis for long-term studies of joint-inflammation and screening and validation of new therapeutics.

    Medical strategy for rheumatoid arthritis (RA) has markedly advanced in recent years. The introductions of biologics and methotrexate as an anchor drug have made it possible to not only suppress pain and inflammation (clinical remission), but also to inhibit joint destruction (structural remission), leading to cure of the disease. In order to achieve this target, it is the most important to diagnose RA early and promote disease remission. However, since the condition and pathology are diverse among patients, optimal treatment for each patient is desired (personalized medicine). Treatment should be performed under consideration of the disease state such as activity, prognosis regarding joint destruction, and complications. It is also important to clarify the patient characteristics, such as responsiveness to the drugs and risk of adverse effects. Biomarkers, such as proteomics and pharmacogenomics (genetic polymorphism, etc.), are indispensable for personalized medicine. We have established a predictive model for methotrexate hepatotoxicity, consisting of 13 SNPs with a sensitivity of 100% and specificity of 89%, although the model should be validated with a larger-scale prospective study. RA is a multifactorial disorder with clinically heterogeneous features. Gene-environment interaction is closely involved in the production of anti-CCP antibodies (ACPA); thereafter, secondary stimuli of joints may lead to symptoms of RA. Joint injury, emotional stress, and infections often trigger the onset of RA. Cure can be achieved through complete remission by early aggressive treatment and returning to the pre-clinical state of RA with environmental improvement.

    Full Text Available Rheumatoid arthritis (RA is an autoimmune disease with erosive and destructive polyarthritis and systemic manifestations. Pulmonary involvement (PI is common in RA. With high-resolution computed tomography, the detection rate of PI in RA is as high as 50%. PI is a direct cause of death in 10–20% of patients with RA. Autoimmune mechanisms play a leading part in the development of PI in RA. Under the hypothesis advanced by M. Selman et al., that impaired alveolocyte regeneration processes after injury rather inflammation underlie the pathogenesis of pulmonary fibrosis. The pathological process is triggered by damaged alveolocytes and characterized by the migration and proliferation of fibroblasts and myofibroblasts, the suppressed apoptosis of the latter, and the enhanced activity of pneumofibrosis-stimulating cytokines. This gives rise to remodeling of the extracellular matrix, including destruction of the basement membrane, angiogenesis, and fibrosis. The paper considers the types of lung injury in RA and main methods for diagnosis and therapy.

    Full Text Available Rheumatoid arthritis (RA is a systemic disease of unknown etiology characterized by a chronic inflammatory process mainly leading to destruction of synovial membrane of small and major diarthrodial joints. The prevalence of RA within the general adult population is about 1% and female subjects in fertile age result mostly involved. It’s an invalidating disease, associated with changes in life quality and a reduced life expectancy. Moreover, we can observe an increased mortality rate in this population early after the onset of the disease. The mortality excess can be partially due to infective, gastrointestinal, renal or pulmonary complications and malignancy (mainly lung cancer and non- Hodgkin lymphoma. Among extra-articular complications, cardiovascular (CV involvement represents one of the leading causes of morbidity and mortality. Every cardiac structure can be affected by different pathogenic pathways: heart valves, conduction system, myocardium, endocardium, pericardium and coronary arteries. Consequently, different clinical manifestations can be detected, including: pericarditis, myocarditis, myocardial fibrosis, arrhythmias, alterations of conduction system, coronaropathies and ischemic cardiopathy, valvular disease, pulmonary hypertension and heart failure. Considering that early cardiac involvement negatively affects the prognosis, it is mandatory to identify high CV risk RA patients to better define long-term management of this population.

    2014-01-01

    When conservation biologists think about infectious diseases, their thoughts are mostly negative. Infectious diseases have been associated with the extinction and endangerment of some species, though this is rare, and other factors like habitat loss and poorly regulated harvest still are the overwhelming drivers of endangerment. Parasites are pervasive and play important roles as natural enemies on par with top predators, from regulating population abundances to maintaining species diversity. Sometimes, parasites themselves can be endangered. However, it seems unlikely that humans will miss extinct parasites. Parasites are often sensitive to habitat loss and degradation, making them positive indicators of ecosystem “health”. Conservation biologists need to carefully consider infectious diseases when planning conservation actions. This can include minimizing the movement of domestic and invasive species, vaccination, and culling.

    Using an appropriate animal model is crucial for mimicking human disease conditions, and various facets including genetics, anatomy, and pathophysiology should be considered before selecting a model. Rabbits (Oryctolagus cuniculus) are well known for their wide use in production of antibodies, eye research, atherosclerosis and other cardiovascular diseases. However, a systematic description of the rabbit as primary experimental models for the study of various human infectious diseases is unavailable. This review focuses on the human infectious diseases for which rabbits are considered a classic or highly appropriate model, including AIDS (caused by HIV1), adult T-cell leukemia-lymphoma (human T-lymphotropic virus type 1), papilloma or carcinoma (human papillomavirus) , herpetic stromal keratitis (herpes simplex virus type 1), tuberculosis (Mycobacterium tuberculosis), and syphilis (Treponema pallidum). In addition, particular aspects of the husbandry and care of rabbits used in studies of human infectious diseases are described. PMID:26678367

    Disease outbreaks, such as those of Severe Acute Respiratory Syndrome in 2003 and the 2009 pandemic A(H1N1) influenza, have highlighted the potential for airborne transmission in indoor environments. Respirable pathogen-carrying droplets provide a vector for the spatial spread of infection with droplet transport determined by diffusive and convective processes. An epidemiological model describing the spatial dynamics of disease transmission is presented. The effects of an ambient airflow, as an infection control, are incorporated leading to a delay equation, with droplet density dependent on the infectious density at a previous time. It is found that small droplets ($\\sim 0.4\\ \\mu$m) generate a negligible infectious force due to the small viral load and the associated duration they require to transmit infection. In contrast, larger droplets ($\\sim 4\\ \\mu$m) can lead to an infectious wave propagating through a fully susceptible population or a secondary infection outbreak for a localised susceptible population...

  14. Infectious diseases and securitization: WHO's dilemma.

    Science.gov (United States)

    Jin, Jiyong; Karackattu, Joe Thomas

    2011-06-01

    The threat posed by infectious diseases has been increasingly framed as a security issue. The UN Security Council's Resolution 1308, which designated HIV/AIDS as a threat to international security, evidenced the securitization process. Using securitization theory as a theoretical tool, this article explores the securitization of infectious diseases in the World Health Organization (WHO). While WHO has tended to securitize infectious diseases since 2000, it has encountered a dilemma in the process because of the inherent asymmetry of interest between developed and developing countries. The act of securitization in WHO currently remains mostly a rhetorical device, since WHO's norms emblematic of securitization have not been backed by operational measures for verification or enforcement due to these asymmetric interests.

    The purpose of this review is to summarize psychosocial factors associated with arthritis pain and highlight recent evidence for psychosocial approaches to managing arthritis pain. By definition, psychosocial factors refer to two dimensions of experience: the psychological (cognitive, affective) and social (interacting with others, engaging in life activities). Psychosocial factors influence the perception of pain and the presence of pain influences psychological well-being and social participation. After discussing the impact of arthritis pain on participation in work, family life, and leisure, evidence for psychosocial interventions is summarized, emphasizing reviews and studies published from January 2000 to August 2006.

    The ocular and systemic characteristics of 160 patients with anterior uveitis and seronegative juvenile rheumatoid arthritis are reviewed. Chronic uveitis occurred in 131 patients, 76% of whom were girls. Both eyes were involved in 70% of the cases. Band keratopathy occurred in 41% of the eyes, cataract in 42%, and secondary glaucoma in 19%. Only 11 patients had uveitis before the onset of arthritis. Notable correlations included a pauciarticular onset of arthritis in 95% of the patients, and positive tests for antinuclear antibody in 82%. Of 29 patients with acute anterior uveitis, 27 were boys. The inflammation responded well to therapy, and serious complications did not occur. At follow-up 21 patients had typical ankylosing spondylitis, and five had sacroiliitis. The incidence of positive results of tests for HLA-B27 antigen was 94%.

    Three hundred and fifteen patients with anterior uveitis associated with juvenile chronic arthritis (JCA) were studied in order to identify the various risk factors for uveitis. Girls were more susceptible to uveitis than boys by a ratio of 3:1. In 94% of cases the uveitis was diagnosed after the development of arthritis. The risk of uveitis was small after seven or more years had elapsed from the onset of arthritis. Patients with pauciarticular onset JCA had the highest risk of uveitis and systemic onset patients the least risk. The presence of circulating antinuclear antibody was also an important marker for an increased risk of uveitis. A regimen for routine screening of patients is suggested.

    2004-07-01

    Reactive oxygen species (ROS) have been shown to play a role in the pathogenesis of arthritides. Luminol was used as the primary reporter of ROS and photons resulting from the chemiluminescence reaction were detected using a super-cooled CCD photon counting system. Luminol was injected intravenously into groups of animals with different models of arthritis. Imaging signal correlated well with the severity of arthritis in focal and pan-arthritis as determined by histological measurement of ROS by formazan. Measurements were highly reproducible, sensitive, and repeatable. In vivo chemiluminescence imaging is expected to become a useful modality to elucidate the role of ROS in the pathogenesis of arthritides and in determining therapeutic efficacy of protective therapies.

    2013-04-24

    The addition of a corticosteroid has become a common practice for the treatment of some infectious diseases, such as meningitis, septic shock, moderate to severe Pneumocystis jirovecii pneumonia. The belief that steroids may have a beneficial effect in the early stage of pro-inflammatory infections explains the renewed interest for these treatments. This review of recent literature helps determine the use of steroids in the treatment of infectious diseases as formal guidance, questionable or rather contraindicated. When there is a clear scientific indication for the use of corticosteroids regardless of the current infection, the latter is never a formal contraindication.

    Infectious sacroiliitis is an uncommon septic arthritis, the diagnosis of which is difficult to establish. We retrospectively examined 14 cases of septic sacroiliitis, by CT (two of whom also had an MRI examination). The patient population consisted of eight men and six women; 9 were African, 8 had tuberculous sacroiliitis and 6 pyogenic sacroiliitis. All the cases showed a pre-sacroiliac soft tissue swelling with ring-like enhancement following intravenous contrast in eight cases. A gas image was observed at the center of the abcess in two cases. Joint narrowing was found in four patients and widening in eight, associated with an image of bone sequestration in seven. CT gave an etiologic orientation in 8 cases, and facilitated the guidance of bone biopsy. MRI showed low signal T1-weighted images and high signal T2 of the subchondral bone, joint space and soft tissue abcess. We conclude that CT is helpful in the evaluation of infectious sacroiliitis, and that further studies are necessary to evaluate the role of MRI in such pathologic processes. (orig.)

    We describe three patients with rheumatoid arthritis who presented with non-specific pulmonary symptoms, a restrictive defect in lung function and bilateral changes on chest radiograph. Lung histology showed characteristic features of cryptogenic organising pneumonitis and treatment with steroids produced significant improvement. The clinical and laboratory features of cryptogenic organising pneumonitis (otherwise known as bronchiolitis obliterans organising pneumonia, 'BOOP') are discussed and compared with those of bronchiolitis obliterans with which the condition should not be confused. Cryptogenic organising pneumonitis should be considered as one of the pulmonary manifestations of rheumatoid arthritis, but lung biopsy is essential to make the diagnosis.

    Antigens of I class HLA system (locus A and B) were investigated in 67 patients of Latvian nationality suffering from juvenile rheumatoid arthritis (JRA). Associations of HLA antigens with juvenile rheumatoid arthritis partially coincided with the ones revealed earlier. Typing established an increased incidence of antigen B27 (p less than 0.01) and gaplotype A2, B40 (p less than 0.01). Antigen B15 possessed a protective action with respect to JRA. Interlocus combinations demonstrated a closer association with the disease than a single antigen. The authors also revealed markers of various clinico-anatomical variants of JRA.

    X-linked agammaglobulinemia (XLA) is a primary immunodeficiency disease caused by mutations in the Bruton's tyrosine kinase (BTK) gene. XLA can also present in combination with juvenile idiopathic arthritis (JIA), the major chronic rheumatologic disease in children. We report herein the first known case of a juvenile patient diagnosed with XLA combined with JIA that later developed into invasive Klebsiella pneumoniae polyarticular septic polyarthritis. An additional comprehensive review of XLA combined with JIA and invasive K. pneumoniae septic arthritis is also presented. XLA was identified by the detection of BTK mutations while the diagnosis of JIA was established by clinical and laboratory assessments. Septic arthritis caused by invasive K. pneumoniae was confirmed by culturing of the synovia and gene detection of the isolates. Invasive K. pneumoniae infections can not only result in liver abscesses but also septic arthritis, although this is rare. XLA combined with JIA may contribute to invasive K. pneumoniae infection.

    Full Text Available The paper considers the problems of comorbidities in patients with rheumatoid arthritis (RA. Two or more RA-related conditions were diagnosed according to the results of the QUEST-RA program implemented in 34 countries. Osteoarthritis along with hypertension, hyperlipidemia, and osteoporosis was detected among the most commonly diseases. Owing to expanded diagnostic capabilities, the recognition and treatment of the comorbidities have recently received much attention, as embodied in the draft Association of Rheumatologists of Russia Guidelines for RA management (2014; Part 1. The concept and major characteristics of secondary osteoarthritis in RA are analyzed. It is precisely the inflammatory process and underlying disease-related risk factors, including treatment, that have impact on the development of secondary osteoarthritis and patients’ quality of life as a whole. All this allows an inference about the mechanisms closely intertwined with the underlying disease for the development of secondary osteoarthritis, which initiates cartilage damage and further remodeling. Primary and secondary osteoarthritis was comparatively analyzed. Particular emphasis is placed on current cartilage biomarkers, their diagnostic value and role in monitoring the efficiency of treatment in clinical trials. The paper provides a comparative analysis of detectable serum and urine biomarkers according to the results of the complex analysis made by the National Institutes of Health. Particular attention is given to cartilage oligomeric matrix protein (COMP. Foreign authors’ investigations suggest that there is a relationship between serum COMP levels and disease severity and joint X-ray changes. There is evidence for the efficacy of hyaluronic acid used in the treatment of secondary osteoarthritis in patients with RA.

    Rheumatoid arthritis (RA) is the most common connective tissue disease of autoimmune origin. The disease is characterized by chronic inflammation leading to bone erosions and organ involvement. RA is a progressive disease. It affects the quality of life, leading to disability and death mainly due to premature cardiovascular disease. Early diagnosis and appropriate treatment are essential for prognosis and quality of life improvement. In 2010 the American College of Rheumatology (ACR) and The European League Against Rheumatism (EULAR) established new RA classification criteria. Besides clinical symptoms it includes two immunologic criteria: rheumatoid factor (RF) and anti-citrullinated protein antibodies (anti-CCP antibodies). RF is the first well-known RA immunologic marker. It is observed in 80-85% of patients with RA. Elevated serum level of RF has been associated with increased disease activity, radiographic progression, and the presence of extraarticular manifestations. The sensitivity of RF is 50-90%, and specificity is 50-95%. Anti-CCP antibodies appear to be a more specific marker than RF. They are often present at the very beginning of the disease, or even years before the first symptoms. The prognostic value of anti-CCP antibodies is well established. High serum level of anti-CCP correlates with poor prognosis and early erosions of the joints. The sensitivity of anti-CCP2 is 48-80%, and specificity is 96-98%. New immunologic markers include anti-carbamylated protein antibodies (anti-CarP) and antibodies against heterogeneous nuclear ribonucleoproteins (anti-hnRNP A2/B1, RA33). Scientists aim to identify a highly sensitive and specific biomarker of the disease that not only has diagnostic and prognostic value but also may predict the response to treatment.

    Full Text Available Rheumatoid Arthritis (RA is a widespread disease and its renal involvement, relatively common, is clinically significant because worsens course and mortality of the primary disease. There is still no agreement on the prevalence of renal disorders in RA: data analysis originates from different sources, as death certificates, autopsies, clinical and laboratory findings and kidney biopsies, each with its limitations. Histoimmunological studies on bioptical specimens of patients with RA and kidney damage, led to clarify prevalent pathologies. In order of frequency: glomerulonephritis and amyloidosis (60-65% and 20-30% respectively, followed by acute or chronic interstitial nephritis. Kidney injury during RA includes secondary renal amyloidosis, nephrotoxic effects of antirheumatic drugs and nephropathies as extra-articular manifestations (rheumatoid nephropathy. Amyloidosis affects survival, increases morbidity and is the main cause of end stage renal disease in patients with RA and nephropathy. Strong association between RA activity and amyloidosis needs the use of immunosuppressive and combined therapies, to prevent this complication and reduce risk of dialysis. Long-lasting and combined RA pharmacotherapy involves various renal side effects. In this review we describe NSAIDs and DMARDs (Disease-Modifying Antirheumatic Drugs nephrotoxicity, particularly by gold compounds, D-penicillamine, cyclosporine A and methotrexate. Rare cases of IgA glomerulonephritis during immunomodulating therapy with leflunomide and TNF blocking receptor (etanercept are reported; real clinical significance of this drug-related nephropathy will be established by development of RA treatment.

    Results obtained in 43 Rheumatoid arthritis (RA) patients with cervical myelopathy are described; all patients showed several alarm signs together with neurological disturbances. Thirty-four cases were operable; nine patients were not operated upon for various reasons (refusal, and general condition). In the surgically treated patients, the changes were localized in the C1-C2 area (n = 20), in the area below C2 (n = 5), or in both (n = 9). The patients were put on skull traction pre- and post-operatively and nursed on a circo-electric bed. Pre-operatively, the duration of traction varied from a few days to weeks (mean 3 weeks). Post-operatively, the patients were given continuous skull traction for 2 1/2-3 months. This procedure yielded neurological improvement and a stable graft in all but two patients. On follow-up, recurrence of neurological complaints was seen in nine patients, in four due to a new slip at a lower level. Three of these cases were reoperated with good results. Twenty-three patients have died: four 'early' (one pre-operatively and three within 6 weeks post-operatively) and 19 'late'. The mean duration of follow-up was 4.5 years. In those who died 'late', the cause of death was due to the effects of an unstable graft in two cases and in the others the causes were not related to changes in the cervical spine. In the 10 patients who are still alive the mean duration of follow-up is 5 years. The nine patients who were not operated upon all died within a year, 4 of them due to consequences of cord compression. If cervical spondylodesis is feasible in an RA patient with myelopathy, the procedure is advocated. PMID:6529877

    The pathogenesis of rheumatoid arthritis (RA), similar to development of a majority of inflammatory and autoimmune disorders, is largely due to an inappropriate or inadequate immune response to environmental challenges. Among these challenges, infectious agents are the undisputed leaders. Since the 1870s, an impressive list of microorganisms suspected of provoking RA has formed, and the list is still growing. Although a definite causative link between a specific infectious agent and the disease has not been established, several arguments support such a possibility. First, in the absence of a defined pathogen, the spectrum of triggering agents may include polymicrobial communities or the cumulative effect of several bacterial/viral factors. Second, the range of infectious episodes (i.e., clinical manifestations caused by pathogens) may vary in the process of RA development from preclinical to late-stage disease. Third, infectious agents might not trigger RA in all cases, but trigger it in a certain subset of the cases, or the disease onset may arise from an unfortunate combination of infections along with, for example, psychological stress and/or chronic joint tissue microtrauma. Fourth, genetic differences may have a role in the disease onset. In this review, two aspects of the problem of "microorganisms and RA" are debated. First, is there an acquired immune deficiency and, in turn, susceptibility to infections in RA patients due to the too frequent and too lengthy infections, which at last break the tolerance of self antigens? Or, second, is there a congenital deficiency in tolerance and inflammation control, which may occur even with ordinary infection frequency and duration? PMID:27582741

    Infectious diseases remain one of the most important limitations to the successful propagation of aquatic animals. Most of the losses caused by pathogens in aquaculture could be prevented by health inspection, adequate environment and sound management practices. Effective control measures, mainly based upon 1) avoidance of pathogens 2) modification of the environment 3) improvement of host resistance 4) vaccination and 5) chemoprophylaxis are described.

    This slide presentation opens with views of the shuttle in various stages of preparation for launch, a few moments after launch prior to external fuel tank separation, a few pictures of the earth,and several pictures of astronomical interest. The presentation reviews the factors effecting the risks of infectious disease during space flight, such as the crew, water, food, air, surfaces and payloads and the factors that increase disease risk, the factors affecting the risk of infectious disease during spaceflight, and the environmental factors affecting immunity, such as stress. One factor in space infectious disease is latent viral reactivation, such as herpes. There are comparisons of the incidence of viral reactivation in space, and in other analogous situations (such as bed rest, or isolation). There is discussion of shingles, and the pain and results of treatment. There is a further discussion of the changes in microbial pathogen characteristics, using salmonella as an example of the increased virulence of microbes during spaceflight. A factor involved in the risk of infectious disease is stress.

    2015-01-01

    Human-driven climatic changes will fundamentally influence patterns of human health, including infectious disease clusters and epidemics following extreme weather events. Extreme weather events are projected to increase further with the advance of human-driven climate change. Both recent and historical experiences indicate that infectious disease outbreaks very often follow extreme weather events, as microbes, vectors and reservoir animal hosts exploit the disrupted social and environmental conditions of extreme weather events. This review article examines infectious disease risks associated with extreme weather events; it draws on recent experiences including Hurricane Katrina in 2005 and the 2010 Pakistan mega-floods, and historical examples from previous centuries of epidemics and 'pestilence' associated with extreme weather disasters and climatic changes. A fuller understanding of climatic change, the precursors and triggers of extreme weather events and health consequences is needed in order to anticipate and respond to the infectious disease risks associated with human-driven climate change. Post-event risks to human health can be constrained, nonetheless, by reducing background rates of persistent infection, preparatory action such as coordinated disease surveillance and vaccination coverage, and strengthened disaster response. In the face of changing climate and weather conditions, it is critically important to think in ecological terms about the determinants of health, disease and death in human populations.

    Full Text Available Septic bursitis is usually caused by bacterial organisms. However, infectious bursitis caused by fungi is very rare. Herein, we present a 68-year-old woman with long-standing rheumatoid arthritis who developed pain, erythema, and swelling of the right olecranon bursa. Aspiration of the olecranon bursa showed a white blood cell count of 3.1×103/μL (41% neutrophils, 30% lymphocytes, and 29% monocytes. Fluid culture was positive for Candida parapsilosis. She was treated with caspofungin 50 mg intravenously daily for 13 days followed by fluconazole 200 mg orally daily for one week. She responded well to this treatment but had recurrent swelling of the bursa. Bursectomy was recommended but she declined this option. This case, together with other reports, suggests that the awareness of uncommon pathogens, their presentation, and predisposing risk factors are important to establish an early diagnosis and prevent long-term complications.

    Arvikar, Sheila L.; Steere, Allen C.

    2015-01-01

    SYNOPSIS In the United States, Lyme arthritis is the most common feature of late stage infection with the tick-borne spirochete, Borrelia burgdorferi, usually beginning months after the initial tick bite. However, in some patients, including most of those seen today, the earlier phases of the infection are asymptomatic and arthritis is the presenting manifestation of the disease. Patients with Lyme arthritis have intermittent or persistent attacks of joint swelling and pain in one or a few large joints, especially the knee, usually over a period of several years, without prominent systemic manifestations. Serologic testing is the mainstay of diagnosis. Synovial fluid PCR testing for B. burgdorferi DNA is often positive prior to treatment, but it is not a reliable marker of spirochetal eradication after antibiotic therapy. Responses to oral or intravenous antibiotic treatment are generally excellent, although a small percentage of patients have persistent synovitis after 2-3 months of oral and IV antibiotics, which usually then responds to anti-inflammatory therapies, disease modifying anti-rheumatic drugs (DMARDs), or synovectomy. This chapter reviews the clinical manifestations, diagnosis, and management of Lyme arthritis. PMID:25999223

    2003-01-01

    Full Text Available Introduction Septic arthritis represents an intra-articular infection caused by pyogenic bacteria. During the earliest childhood it is considered to be a systemic septic condition and demands early diagnosis and prompt surgical treatment. Material and methods This is a retrospective analysis of patients with septic arthritis treated at the Department of Orthopedics of the Pediatric Surgery Clinic in Novi Sad, over a 10-year period. We are also presenting a case of a 12-day-old newborn baby, with clear radiological signs of osteoarthritis of the right knee. Results A retrospective study included the period 1991-2000, and showed that 15 patients, aged 10 days - 12 months were treated for osteoarthritis. The most common localization was the hip, in 60% of cases. In 11 patients the causative agent was Staphylococcus aureus while in the 4 remaining patients the bacteriologic finding was negative. One patient died of generalized sepsis. Discussion In neonates and infants septic arthritis is characterized by atypical clinical picture, often causing delayed diagnosis. In the initial phases of the disease ultrasonographic findings were of greater use compared to radiological imaging, due to relatively late appearance of radiological signs of disease. Conclusions Due to possible development of serious and irreversible damage, even lethal outcome, septic arthritis requires early diagnosis, prompt administration of antibiotics and early surgical treatment. It is a quite unique area in Pediatric Orthopedics where missed or delayed diagnosis may have serious consequences.

These disorders can result in problems later in life, so survey of correlation between rheumatoid arthritis and hearing disorders is important . Methods: This was a case-control study which has done from December 2004 to August 2006 at Shaheed Sadoughi hospital in Yazd. In this study, 50 Rheumatoid arthritis patients as case group (100 ears with 50 persons as control group who were of the same age, sex and job (100 ears were compared. Results: Patients were 21-67 years old and the mean age was 47.58 years(It was the same as the control group.From 50 cases (controls 42 were women and 8 were men . Audiometric tests in different frequencies showed that hearing loss in high frequencies, especially in 8000 Hz was significantly different in the two groups. Also, acoustic reflex was absent in case group and this too was significantly different.The evaluation of sensory neural hearing loss showed that this hearing loss was sensory, not neural . Conclusion: In Rheumatoid arthritis, middle and inner ear disorders have been shown. But some patients aren't aware of their hearing loss and they have no clinical complains, so frequent evaluation of audiometric tests is recommended. Hearing disorders can be controlled by therapeutic and rehabilitation procedures in these patients.

    2016-09-01

    Systemic-onset juvenile idiopathic arthritis (SoJIA) is a systemic inflammatory disease which has up to now been classified as a category of juvenile idiopathic arthritis. However, in this context, systemic inflammation has been associated with dysregulation of the innate immune system, suggesting that it may rather be part of the spectrum of autoinflammatory disorders. The disease is in fact unique with regard to the other JIA categories, in terms of clinical manifestations, prognosis, and response to conventional immunosuppressant therapies. It is characterized clinically by fever, lymphadenopathy, arthritis, rash, and serositis. IL-1 and IL-6 play a major role in the pathogenesis of SoJIA, and treatment with IL-1 and IL-6 inhibitors has shown to be highly effective. However, complications of SoJIA, including macrophage activation syndrome, limitations in functional outcome by arthritis and long-term damage from chronic inflammation continue to be a major issue in patients' care. Recent advances on the pathogenesis and treatment have revolutionized the care and prognosis of this potentially life-threatening pediatric condition.

    The aim of this cross-sectional study was to review the incidence of the dry eye syndrome in rheumatoid arthritis (RA) patients, evaluate the association among the incidence of the dry eye syndrome, presence of positive rheumatoid factor (RF), the RA stage, and the duration of the disease. The group consisted of altogether 100 patients, 16 men and 84 women; the average age was 58.9 years (SD 14.6). The average duration of RA was 12.3 years, SD 11.0. In each patient, the Schirmer test I was performed, the presence of the LIPCOF (Lid Parallel Conjunctival Folds) on the slit lamp was assessed, the BUT (Tear Break-Up Time) was measured and vital fluorescein staining was performed. In each patient the data of the presence or absence of the RF in the serum, RA severity according to the X-ray examination, and the disease duration were recorded. The Pearson's association test for nominal variables was used for statistical evaluation of the association between the rheumatoid arthritis presence and the dry eye syndrome. In our group of 100 patients, the Schirmer test I was positive in 67% of patients. Positive BUT was marked in 84 % of patients. The conjunctival folds were present in 45 % of patients only. The pathological findings after cornea fluorescein staining appeared in 18 % of patients. The dry eye syndrome incidence was marked in 74% of patients with RA. Subjective difficulties were declared by 38.3% of patients only. The local treatment was already established in 23.0% of patients only. We did not find statistically significant correlation between the RF positive rheumatoid arthritis appearance and dry eye syndrome, nor between the stage of the rheumatoid arthritis and presence of the dry eye syndrome. We proved statistical connection between the presence of dry eye syndrome and the duration of rheumatoid arthritis longer than 10 years. Keratoconjunctivitis sicca is the most common ocular complication in rheumatoid arthritis patients. We proved the connection

    Full Text Available Septic arthritis is a clinical emergency requiring prompt diagnosis and treatment to avoid significant morbidity and mortality. Polyarticular septic arthritis (PASA accounts for 15% of all infectious arthritides and rarely occurs in immunocompetent adults. Staphylococcus aureus is the most commonly isolated organism, with infection primarily affecting knees, shoulders, elbows, and hips. The morbidity associated with PASA is very high, and mortality in treated cases of PASA may be as high as 50% of cases. We report a case of PASA with associated epidural abscess in a healthy adult male, who presented with complaints of arthralgia and limited range of motion of his left shoulder, wrist, and ankle. He also presented with low back pain and motor weakness associated with an epidural abscess spanning L2-S1, with multilevel vertebral osteomyelitis. Surgical washout of the affected joints as well as decompressive laminectomies was performed, and he received a standard course of intravenous antibiotics. Staphylococcus aureus was isolated from joint aspirations and from blood cultures. The patient had a full neurological and functional recovery postoperatively with no sequelae. To the best of our knowledge this is the only case report of Staphylococcus aureus PASA with concomitant epidural abscess in an immunocompetent adult.

    Full Text Available The problem of industrial poultry farming is the emergence of a growing birds’ arthritis. Inflamed joints are usually seen in poultry and accompanied by the inability to take food and water. The most characteristic of this problem in broiler chickens, young chickens of egg cross, i.e. birds of a short period of use. This is the reason for their rejection of the herd. Culling chickens are 10%, which furthermore reduces the total amount of livestock and leads to a reduction in the cost-effectiveness of growing birds. The analysis of our data gives a reason to believe that the main reason for culling poultry is acute inflammation of the joints or arthri-tis. According to the authors to ensure optimal rearing program, which should include the prevention of premature retirement of birds not only due to infectious diseases, but also the prevention of metabolic disorders and the exclusion of factors that could cause disruption of immunological reactivity. Currently, this program needs to be improved, which is particularly important in relation to vaccine pre-vention

  18. Photodynamic therapy can induce a protective innate immune response against murine bacterial arthritis via neutrophil accumulation.

    Directory of Open Access Journals (Sweden)

    Masamitsu Tanaka

    Full Text Available BACKGROUND: Local microbial infections induced by multiple-drug-resistant bacteria in the orthopedic field can be intractable, therefore development of new therapeutic modalities is needed. Photodynamic therapy (PDT is a promising alternative modality to antibiotics for intractable microbial infections, and we recently reported that PDT has the potential to accumulate neutrophils into the infected site which leads to resolution of the infection. PDT for cancer has long been known to be able to stimulate the innate and adaptive arms of the immune system. METHODOLOGY/PRINCIPAL FINDINGS: In the present study, a murine methicillin-resistant Staphylococcus aureus (MRSA arthritis model using bioluminescent MRSA and polystyrene microparticles was established, and both the therapeutic (Th-PDT and preventive (Pre-PDT effects of PDT using methylene blue as photosensitizer were examined. Although Th-PDT could not demonstrate direct bacterial killing, neutrophils were accumulated into the infectious joint space after PDT and MRSA arthritis was reduced. With the preconditioning Pre-PDT regimen, neutrophils were quickly accumulated into the joint immediately after bacterial inoculation and bacterial growth was suppressed and the establishment of infection was inhibited. CONCLUSIONS/SIGNIFICANCE: This is the first demonstration of a protective innate immune response against a bacterial pathogen produced by PDT.

    2012-03-01

    Full Text Available Rheumatoid Arthritis (RA is a chronic auto-immune disease characterized by painful inflammation of the joints and surrounding tissues, leading to long term disability. Rheumatoid arthritis can begin at any age but has its peak between 35 to 55 years of age. RA shows hereditary linkage. Women and smokers are most often affected. The patient doesn’t feel any symptoms during inactive state of the disease. RA progresses in a symmetrical pattern involving both the sides of the body. Once rheumatoid arthritis is confirmed by diagnosis, treatment should start as early as possible. The treatment for rheumatoid arthritis focuses initially on reducing the joint inflammation and pain with the use of analgesics and anti-inflammatory agents. In the next stage, joint function is restored by administering Disease Modifying Anti-rheumatic Drugs (DMARDs thus preventing joint deformity. Treatment is generally based on the degree of severity of RA. Patients with mild RA are advised to take rest and are prescribed analgesics and anti-inflammatory medicines, which include fast acting drugs like NSAIDs. Slow acting drugs like (DMARDs such as methotrexate, sulfasalazine, lelflunomide etc., and Body’s reaction modifiers (BRMs such as rituximab, anankinra, infliximab etc., are reserved for patients suffering from moderate to severe RA. The patient is advised to undertake regular exercises like walking, stretching, swimming or cycling, which are aimed at reducing body weight. The patient suffering from arthritis can carry out his normal day-to-day activities with the help of proper medication and regular exercise.

    Water samples collected throughout several reclamation facilities were analyzed for the presence of infectious Cryptosporidium parvum by the focus detection method-most-probable-number cell culture technique. Results revealed the presence of infectious C. parvum oocysts in 40% of the final disinfected effluent samples. Sampled effluent contained on average seven infectious oocysts per 100 liters. Thus, reclaimed water is not pathogen free but contains infectious C. parvum.

    Treatment with systemic immunomodulatory agents is indicated for patients with moderate to severe plaque psoriasis and psoriatic arthritis. In these patients, surgery may confer an increased risk of infectious or surgical complications. We conducted a literature review to examine studies addressing the use of methotrexate, cyclosporine, and targeted immunomodulatory agents (tumor necrosis factor-alfa inhibitors, interleukin [IL]-12/23 inhibitors, IL-17 inhibitors) in patients undergoing surgery. We examined 46 total studies; the majority were retrospective studies in patients with rheumatoid arthritis and inflammatory bowel disease. One study in patients with psoriasis and psoriatic arthritis reviewed 77 procedures and did not find an elevated risk of postoperative complications with tumor necrosis factor-alfa and IL-12/23 inhibitors even with major surgeries. Based on level III evidence, infliximab, adalimumab, etanercept, methotrexate, and cyclosporine can be safely continued through low-risk operations in patients with psoriasis and psoriatic arthritis. For moderate- and high-risk surgeries, a case-by-case approach should be taken based on the patient's individual risk factors and comorbidities. PMID:27461230

    Pulmonary complications remain among the most frequent causes of morbidity and mortality for individuals with HIV despite the advent of antiretroviral therapy (ART) and improvement in its efficacy and availability. The prevalence of non-infectious pulmonary diseases is rising in this population, reflecting both an increase in smoking and the independent risk associated with HIV. The unique mechanisms of pulmonary disease in these patients remain poorly understood, and direct effects of HIV, genetic predisposition, inflammatory pathways, and co-infections have all been implicated. Lung cancer, chronic obstructive pulmonary disease (COPD), and pulmonary hypertension are the most prevalent non-infectious pulmonary diseases in persons with HIV, and the risk of each of these diseases is higher among HIV-infected (HIV+) persons than in the general population. This review discusses the latest advances in the literature on these important complications of HIV infection. PMID:27121734

    The global nature of the threat posed by new and reemerging infectious diseases will require international cooperation in identifying, controlling, and preventing these diseases. Because of this need for international cooperation, international law will certainly play a role in the global strategy for the control of emerging diseases. Recognizing this fact, the World Health Organization has already proposed revising the International Health Regulations. This article examines some basic problems that the global campaign against emerging infectious diseases might face in applying international law to facilitate international cooperation. The international legal component of the global control strategy for these diseases needs careful attention because of problems inherent in international law, especially as it applies to emerging infections issues.

    The past few years, much attention has been given to the problems regarding new and emerging infectious diseases. Four groups may be considered: (1) new agents discovered among the causes of classical medical syndromes, these do not constitute new dangers but decrease the proportion of unknown causes within these syndromes; (2) increased importance of infectious agents resulting from modified ways of living or production procedures; (3) the really new agents, the spread of which is generally favoured by the same factors and (4) organisms with acquired resistance against antibiotics and pesticides. There is need for extended epidemiological surveillance, that can be improved in our country by better collaboration between different organisations. Most importantly epidemiological surveillance should be organized on an European level with the entire support of our regional and federal authorities.

    2016-01-01

    Quantitatively mapping the spatial distributions of infectious diseases is key to both investigating their epidemiology and identifying populations at risk of infection. Important advances in data quality and methodologies have allowed for better investigation of disease risk and its association with environmental factors. However, incorporating dynamic human behavioural processes in disease mapping remains challenging. For example, connectivity among human populations, a key driver of pathogen dispersal, has increased sharply over the past century, along with the availability of data derived from mobile phones and other dynamic data sources. Future work must be targeted towards the rapid updating and dissemination of appropriately designed disease maps to guide the public health community in reducing the global burden of infectious disease.

    2005-01-01

    The purpose of our study is to emphasize the central role of ultrasound (US) in finding the cause of abdominal pain in children. Ultrasound of the lower abdomen quadrant should be considered in all cases in which the clinical signs and symptoms are not diagnostic of appendicitis. There is a wide range of clinical syndromes and diseases which can easily be diagnosed using a high resolution ultrasound with adjunct of color and power Doppler. The spectrum of abnormalities includes appendicitis, mesenteric lymphadenitis, infectious ileocecitis, Crohn's disease, intussusception, ovarian cysts, and encysted cerebrospinal fluid. One of the most common causes of acute abdominal pain in children is acute terminal ileitis (infectious ileocecitis) with mesenteric lymphadenitis. Ultrasound is the best tool to rapidly differentiate this disease from acute appendicitis, and prevent unnecessary laparotomy (Ref. 12). PMID:16201735

    To describe the findings of magnetic resonance imaging in infectious myositis and to determine their value for differentiation between ruberculous and bacterial myositis. Magnetic resonance images of ten proven cases of infectious myositis (five tuberculous and five bacterial) were retrospectively reviewed in the light of clinical and laboratory findings. On the basis of magnetic resonance images, signal intensity of the mass, the presence or absence of an abscess, signal intensity of the peripheral wall, patterns of contrast enhancement, and associated findings were evaluated. Compared with those of bacterial myositis, the symptoms of tuberculous myositis lasted longer but there were no difinite local inflammatory signs. In three of five cases of bacterial myositis there were specific medical records;trauma in two cases and systemic lupus erythematosus in one. All tuberculous myositis cases involved a single muscle, but bacterial myositis affected multipe muscles in three cases(60%). All but one case showed a mass in the involved muscles. In one bacterial case, there was diffuse swelling in the involved muscle. On T1-weighted images, eight infectious cases showed low signal intensity;two, of the bactrerial type, showed subtle increased signal intensity. all cases demonstrated high signal intensity on t2-weighted images. The signal intensity of peripheral wall was slightly increased on T1-weighted images, but low on T2-weighted. In four cases there was associated cellulitis, and in one case each, adjacent joint effusion and deep vein thrombosis were seen. After gadolinium infusion, peripheral rim enhancement was noted in nine cases and heterogeneous enhancement in one. After magnetic resonance imaging of infectious myositis, the characteristic finding was an abscessed lesion, with the peripheral wall showing high signal intensity on T1-weighted images and low signal intensity on T2 weighted. Although we found it difficult to differentiate bacterial from tuberculous

  6. Epidemiological monitoring for emerging infectious diseases

    Greene, Marjorie

    2010-04-01

    The Homeland Security News Wire has been reporting on new ways to fight epidemics using digital tools such as iPhone, social networks, Wikipedia, and other Internet sites. Instant two-way communication now gives consumers the ability to complement official reports on emerging infectious diseases from health authorities. However, there is increasing concern that these communications networks could open the door to mass panic from unreliable or false reports. There is thus an urgent need to ensure that epidemiological monitoring for emerging infectious diseases gives health authorities the capability to identify, analyze, and report disease outbreaks in as timely and efficient a manner as possible. One of the dilemmas in the global dissemination of information on infectious diseases is the possibility that information overload will create inefficiencies as the volume of Internet-based surveillance information increases. What is needed is a filtering mechanism that will retrieve relevant information for further analysis by epidemiologists, laboratories, and other health organizations so they are not overwhelmed with irrelevant information and will be able to respond quickly. This paper introduces a self-organizing ontology that could be used as a filtering mechanism to increase relevance and allow rapid analysis of disease outbreaks as they evolve in real time.

This is the case of an 18 month old female patient whose first sign of disease was torticollis due to an underlying atlanto-axial subluxation. Three months later, bilateral knee arthritis developed and she was diagnosed with Juvenile Idiopathic Arthritis. Throughout the disease a persistent elevation of liver enzymes was noted, combined with positive antinuclear antibodies and hypergammaglobulinemia, reaching the diagnosis of concomitant autoimmune hepatitis.

    The introduction of disease-modifying antirheumatic drugs has created new demands on imaging to early identify patients with rheumatoid arthritis and opened new prospects in therapeutic management of patients with aggressive disease. Therefore, new imaging modalities such as magnetic resonance imaging and ultrasound have developed during the past few years in this field. In some cases, both magnetic resonance imaging and ultrasound may be also useful in making the distinction between early rheumatoid arthritis and other joints abnormalities, including early psoriatic arthritis. This article will review key aspects of important advances in imaging in rheumatoid arthritis, particularly focusing on magnetic resonance imaging and ultrasound.

  19. Cytokines in juvenile rheumatoid arthritis (JRA).

    Mangge, H; Schauenstein, K

    1998-06-01

    Juvenile rheumatoid arthritis (JRA), unlike rheumatoid arthritis of adulthood (RA), is a heterogenous disease comprising at least five subtypes that differ in clinical course and prognosis, and require different therapeutical approaches. As compared to RA, the production of local and systemic cytokines in JRA have not yet been as extensively investigated. In this article we review the available literature on cytokine expression in serum and synovial fluid in all five different subtypes of JRA. Even though the data are still fragmentary, the evidence so far suggests that the determination of serum cytokines yields relevant information as to clinical subtype and inflammatory activity of the disease. Furthermore, the cytokine data suggest that the pathogenesis of JRA may even by more heterogenous than defined by the clinical subtypes. Finally, future directions of research in this area are proposed, and-based on the latest results-arguments for (anti)cytokine therapies in JRA are critically discussed.

    Juvenile rheumatoid arthritis (JRA) is the most common rheumatologic disease in children. Moreover, multiple sclerosis (MS) is the most frequent demyelinating disease and has been associated with various chronic inflammatory diseases. However, its association with JRA has not been frequently described. Autoimmunity in both JRA and MS has been documented in the scientific literature, although there has been no definitive finding that patients with JRA are prone to the development of MS. An increasing frequency of MS resulting from an increased use of antitumor necrosis factor agents in the treatment of rheumatoid arthritis and other chronic inflammatory diseases has been reported recently. In this study, we report on the development of MS in a patient with JRA who did not have a history of antitumor necrosis factor use.

    2015-08-01

    Full Text Available Juvenile Rheumatoid Arthritis (JRA is a systemic disease on childhood, which has chronic arthritis as its most prominent manifestation. One very common complication of JRA is growth disturbance. JRA involving temporomandibular joint usually result in mandibular growth retardation which eventually can lead to micrognathia, retrognathia, malocclusion and other mandibulofacial developmental aberrations. Factors considered to be the cause of these growth and developmental disturbances are: congenital, the disease's direct effect on the condyle, functional deficiency of the temporomandibular joint, duration, age of disease onset and type of the JRA and corticosteroid therapy. However, the mechanism for the mandibulofacial growth and developmental aberrations due to JRA are not fully understood. This literature review will discuss the hypotheses concerning mechanisms of those growth and developmental disturbances, especially based on clinical and radiographic studies on JRA cases.

    The authors studied the histopathologic evolution of arthritis in nonirradiated and irradiated hamsters infected with Borrelia burgdorferi. Nonirradiated hamsters injected in the hind paws with B. burgdorferi developed an acute inflammatory reaction involving the synovium, periarticular soft tissues, and dermis. This acute inflammatory reaction was short-lived and was replaced by a mild chronic synovitis as the number of detectable spirochetes in the synovium, periarticular soft tissues, and perineurovascular areas diminished. Exposing hamsters to radiation before inoculation with B. burgdorferi exacerbated and prolonged the acute inflammatory phase. Spirochetes also persisted longer in the periarticular soft tissues. A major histopathologic finding was destructive and erosive bone changes of the hind paws, which resulted in deformation of the joints. These studies should be helpful in defining the immune mechanism participating in the onset, progression, and resolution of Lyme arthritis.

    In studies of experimental Lyme disease, a major obstacle has been the unavailability of a suitable animal model. We found that irradiated LSH/Ss Lak hamsters developed arthritis after injection of Borrelia burgdorferi in the hind paws. When nonirradiated hamsters were injected in the hind paws with B. burgdorferi, acute transient synovitis was present. A diffuse neutrophilic infiltrate involved the synovia and periarticular structures. The inflammation was associated with edema, hyperemia, and granulation tissue. Numerous spirochetes were seen in the synovial and subsynovial tissues. The histopathologic changes were enhanced in irradiated hamsters. The onset and duration of the induced swelling were dependent on the dose of radiation and the inoculum of spirochetes. Inoculation of irradiated hamsters with Formalin-killed spirochetes or medium in which B. burgdorferi had grown for 7 days failed to induce swelling. This animal model should prove useful for studies of the immune response to B. burgdorferi and the pathogenesis of Lyme arthritis.

    Full Text Available Psoriatic arthritis (PsA is an inflammatory arthritis associated with psoriasis. In addition to skin and joint involvement, there is increasing evidence suggesting that patients with PsA also have an increase in risk of clinical and subclinical cardiovascular diseases, mostly due to accelerating atherosclerosis. Both conventional and nonconventional cardiovascular risk factors contribute to the increased cardiovascular risk in PsA. Chronic inflammation plays a pivotal role in the pathogenesis of atherosclerosis in PsA, acting independently and/or synergistically with the conventional risk factors. In this paper, we discuss the current literature indicating that patients with PsA are at risk of cardiovascular diseases.

    Full Text Available Rat bite fever is rare in Western countries. It can be very difficult to diagnose as blood cultures are typically negative and a history of rodent exposure is often missed. Unless a high index of suspicion is maintained, the associated polyarthritis can be mistaken for rheumatoid arthritis. We report a case of culture-positive rat bite fever in a 46-year-old female presenting with fever and polyarthritis. The clinical presentation mimicked rheumatoid arthritis. Infection was complicated by discitis, a rare manifestation. We discuss the diagnosis and management of this rare zoonotic infection. We also review nine reported cases of rat bite fever, all of which had an initial presumptive diagnosis of a rheumatological disorder. Rat bite fever is a potentially curable infection but can have a lethal course if left untreated.

    2015-01-01

    Given the varied therapeutic options available for the management of psoriatic arthritis (PsA), recommendations for the management of PsA have been developed by several expert groups. These recommendations deal mainly with pharmacological treatments. At the international level, 2 recommendations sets are available: these have been developed by the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) and by the European League against Rheumatism (EULAR). These recommendations were published in 2009 and in 2012, respectively; and updates of these recommendations are currently ongoing. The first sets of recommendations dealt with non-steroidal anti-inflammatory drugs, glucocorticoids, conventional synthetic disease modifying drugs and tumour necrosis factor inhibitors; the 2015 sets of recommendations also deal with new drugs with other mechanisms of action, namely ustekinumab, secukinumab and apremilast. In the present paper, we will review these management recommendations.

    2016-01-01

    Rheumatoid arthritis (RA) is a chronic systemic connective tissue disease. The development of comorbidities often occurs in the course of RA. One of them is osteoporosis, which has serious social and economic effects and may contribute to the increase in the degree of disability and premature death of the patient. Due to the young age in which RA disease occurs, densitometry (DXA) of the lumbar spine is the basic examination in osteoporosis diagnostics. In the course of RA, much more frequently than in healthy persons of the same age, osteoporotic fractures of vertebral bodies occur, which hinder a correct assessment in the DXA test. Rheumatoid arthritis patients often undergo computed tomography (CT) examination of the abdominal cavity for other medical indications than suspected spinal injury. Then, CT examination may also serve for the assessment of bone density, especially in patients with osteoporotic fractures.

    2014-01-01

    In recent years, it has become increasingly clear that the term Juvenile Idiopathic Arthritis (JIA) comprises not one disease but several. Moreover, recent studies strongly suggest that some of these clinico-pathophysiologic entities appear to cross current diagnostic categories. The ultimate goal of the JIA classification is to facilitate development of better, more specific therapy for different forms of disease though improved understanding of pathophysiology. The past two decades have witnessed significant advances in treatment and improved outcomes for many children with chronic arthritis. However, understanding of the basic biologic processes underlying these diseases remains far from complete. As a result, even the best biologic agents of today represent "halfway technologies". Because they do not treat fundamental biologic processes, they are inherently expensive, need to be given for a long time in order to ameliorate the adverse effects of chronic inflammation, and do not cure the disease. Pediatric rheumatology is now entering an era in which diagnostic categories may need to change to keep up with discovery. A more precise, biologically based classification is likely to contribute to development of more specific and improved treatments for the various forms of childhood arthritis. In this review, we discuss how genetic, gene expression, and immunologic findings have begun to influence how these diseases are understood and classified.

    Full Text Available Septic arthritis of the temporomandibular joint (TMJ is a rare event that has only been reported a few dozen times worldwide. This case is remarkable for septic arthritis of the TMJ joint in an otherwise healthy male. Case Report: A 24-year-old male presented to the emergency department with periauricular swelling, erythema, fever, myalgia′s and generalized joint pain. He had previously sought medical attention and was placed on ciprofloxacin. However, he developed facial swelling and a rash and had to discontinue the antibiotic. On physical exam the patient had a large swelling and tenderness in his left periauricular area, with erythema and deviation of the right mandible which limited his ability to open the mouth. A computed tomography showed mild asymmetric soft tissue swelling in the left pharyngeal region but did not show joint effusion. Subsequent magnetic resonance imaging did show effusion of the joint space. The effusion was drained, and the synovial fluid was submitted for gram stain, culture, and sensitivity. The cultures grew menthicillin sensitive Staphyloccocus Aureus. The patient was discharged to complete a two week course of intravenous (IV Ceftriaxone and IV Vancomycin via home infusion. Conclusion: Septic Arthritis of the TMJ is a rare event with very specific clinical symptoms. Due to the low sensitivity of the computed tomography scan, magnetic resonance imaging should be considered when computed tomography scan is negative for TMJ effusion.

  5. Fibromyalgia Complicating Disease Management in Rheumatoid Arthritis

    Objective: To evaluate frequency of fibromyalgia in rheumatoid arthritis and its effect on disease activity score. Study Design: Cross-sectional study. Place and Duration of Study: The Indus Hospital, Karachi, from December 2010 to May 2011. Methodology: All adult patients of either gender diagnosed as rheumatoid arthritis on the basis of clinical, laboratory and X-ray criteria were included in the study. The sample data was separated into two groups depending on presence or absence of fibromyalgia and 28 joint disease activity score (DAS-28) value was evaluated. Results: There were 31 (25.83%) patients with rheumatoid arthritis and fibromyalgia (RAFM) out of the total 120. The median (IQR) age of patients was 40 (32 - 51) years. All were females. The overall female frequency was 79 (88.8%). The median (IQR) DAS-28 score in RA group was 4.9 (3.66 - 5.71), while the median (IQR) DAS-28 score in RAFM was 7.04 (6.62 - 7.64) [p < 0.0001]. The number of patient getting combination therapy of DMARD in RAFM group was 61.3% while in RA group was 42.7%. Conclusion: DAS-28 was found to be significantly higher in RAFM patients probably because of higher perception of pain. (author)

  6. The conundrum of juvenile psoriatic arthritis.

    Ravelli, Angelo; Consolaro, Alessandro; Schiappapietra, Benedetta; Martini, Alberto

    2015-01-01

    Juvenile psoriatic arthritis (JPsA) has provided paediatric rheumatologists with a controversial topic for many years. The principal area of contention centres on the discordance between its treatment as a single diagnostic category in current classification schemes and the demonstration of its heterogeneous nature. A further point of debate is the distinctiveness of JPsA as an entity. Owing to these uncertainties, the concept of JPsA has evolved over the years and there have been several changes in its definition and diagnostic criteria. Recently, strong evidence has been provided that the spectrum of JPsA include at least two distinct subgroups, one that has the same characteristics as early-onset ANA-positive JIA, and another that is part of the spectrum of spondyloarthropathies and resembles the forms of psoriatic arthritis in adults that belong to the same disease family. These findings call for a revision of the classification of childhood arthritis, that refutes the assumptions that children with JPsA constitute a single homogeneous population and that JPsA should be considered an individual disease entity.

The disease activity of patients with rheumatoid arthritis was measured using the disease activity score 28. Radiographs of the cervical spine included lateral views taken in flexion, extension, neutral position of the neck and anterioposterior and odontoid projection view. Asymptomatic cervical spine subluxation was found in 17 of the 100 patients (17%. The prevalence of, anterior atlantoaxial subluxation, atlantoaxial impaction and subaxial subluxation was 10(10%, 5(5% and 6(6%, respectively. Posterior subluxation was not detected. The only characteristic that showed meaningful relationship with cervical spine subluxation was CRP (P=0.036. Our results showed that patients with RA, who have cervical spine subluxation cannot be distinguished on the basis of symptoms. Cervical spine involvement is common and may be asymptomatic, indicating routine cervical spine imaging is needed in patients with RA.

    TIA-1 and TTP are AU-rich element-binding proteins that prevent the pathological overexpression of tumor necrosis factor α (TNF-α). TIA-1 inhibits the translation of TNF-α transcripts, whereas TTP promotes the degradation of TNF-α transcripts. Here we show that TIA-1 and TTP function as arthritis suppressor genes: TIA-1–/– mice develop mild arthritis, TTP–/– mice develop severe arthritis, and TIA-1–/–TTP–/– mice develop very severe arthritis. Peritoneal macrophages derived from all three geno...

  9. K/BxN serum transfer arthritis as a model for human inflammatory arthritis

    Full Text Available The K/BxN serum-transfer arthritis (STA model is a murine model in which the immunological mechanisms occurring in rheumatoid arthritis (RA and other arthritides can be studied. To induce K/BxN STA, serum from arthritic transgenic K/BxN mice is transferred to naive mice and manifestations of arthritis occur a few days later. The inflammatory response in the model is driven by autoantibodies against the ubiquitously expressed self-antigen, glucose-6-phosphate isomerase (G6PI, leading to the formation of immune complexes that drive the activation of different innate immune cells such as neutrophils, macrophages and possibly mast cells. The pathogenesis further involves a range of immune mediators including cytokines, chemokines, complement factors, Toll-like receptors, Fc receptors, and integrins, as well as factors involved in pain and bone erosion. Hence, even though the K/BxN STA model mimics only the effector phase of RA, it still involves a wide range of relevant disease mediators. Additionally, as a murine model for arthritis, the K/BxN STA model has some obvious advantages. Firstly, it has a rapid and robust onset of arthritis with 100% incidence in genetically identical animals. Secondly, it can be induced in a wide range of strain backgrounds and can therefore also be induced in gene-deficient strains to study the specific importance of disease mediators. Even though G6PI might not be an essential autoantigen, for example, in RA, the K/BxN STA model is a useful tool to understand how autoantibodies in general drive the progression of arthritis by interacting with downstream components of the innate immune system. Finally, the model has also proven useful as a model wherein arthritic pain can be studied. Taken together, these features make the K/BxN STA model a relevant one for RA and it is a potentially valuable tool especially for the pre-clinical screening of new therapeutic targets for RA and perhaps other forms of inflammatory

    Highlights: •Sirt2 expression decreases in collagen-induced arthritis (CIA). •Sirt2 knockout aggravates severity of arthritis in mice with CIA. •Sirt2 knockout increases levels of pro-inflammatory factors in the serum. •Sirt2 deacetylates p65 and inhibits pro-inflammatory factors expression. •Sirt2 rescue abates severity of arthritis in mice with CIA. -- Abstract: Arthritis is a common autoimmune disease that is associated with progressive disability, systemic complications and early death. However, the underling mechanisms of arthritis are still unclear. Sirtuins are a NAD{sup +}-dependent class III deacetylase family, and regulate cellular stress, inflammation, genomic stability, carcinogenesis, and energy metabolism. Among the sirtuin family members, Sirt1 and Sirt6 are critically involved in the development of arthritis. It remains unknown whether other sirtuin family members participate in arthritis. Here in this study, we demonstrate that Sirt2 inhibits collagen-induced arthritis (CIA) using in vivo and in vitro evidence. The protein and mRNA levels of Sirt2 significantly decreased in joint tissues of mice with CIA. When immunized with collagen, Sirt2-KO mice showed aggravated severity of arthritis based on clinical scores, hind paw thickness, and radiological and molecular findings. Mechanically, Sirt2 deacetylated p65 subunit of nuclear factor-kappa B (NF-κB) at lysine 310, resulting in reduced expression of NF-κB-dependent genes, including interleukin 1β (IL-1β), IL-6, monocyte chemoattractant protein 1(MCP-1), RANTES, matrix metalloproteinase 9 (MMP-9) and MMP-13. Importantly, our rescue experiment showed that Sirt2 re-expression abated the severity of arthritis in Sirt2-KO mice. Those findings strongly indicate Sirt2 as a considerably inhibitor of the development of arthritis.

  11. How to make epidemiological training infectious.

    Full Text Available Modern infectious disease epidemiology builds on two independently developed fields: classical epidemiology and dynamical epidemiology. Over the past decade, integration of the two fields has increased in research practice, but training options within the fields remain distinct with few opportunities for integration in the classroom. The annual Clinic on the Meaningful Modeling of Epidemiological Data (MMED at the African Institute for Mathematical Sciences has begun to address this gap. MMED offers participants exposure to a broad range of concepts and techniques from both epidemiological traditions. During MMED 2010 we developed a pedagogical approach that bridges the traditional distinction between classical and dynamical epidemiology and can be used at multiple educational levels, from high school to graduate level courses. The approach is hands-on, consisting of a real-time simulation of a stochastic outbreak in course participants, including realistic data reporting, followed by a variety of mathematical and statistical analyses, stemming from both epidemiological traditions. During the exercise, dynamical epidemiologists developed empirical skills such as study design and learned concepts of bias while classical epidemiologists were trained in systems thinking and began to understand epidemics as dynamic nonlinear processes. We believe this type of integrated educational tool will prove extremely valuable in the training of future infectious disease epidemiologists. We also believe that such interdisciplinary training will be critical for local capacity building in analytical epidemiology as Africa continues to produce new cohorts of well-trained mathematicians, statisticians, and scientists. And because the lessons draw on skills and concepts from many fields in biology--from pathogen biology, evolutionary dynamics of host--pathogen interactions, and the ecology of infectious disease to bioinformatics, computational biology, and

    Epidemiological surveillance, namely the continuous monitoring of diseases and health determinants in a population, has developed over the past fifteen years, in the sphere of human health as well as in animal health. All epidemiological surveillance networks include the following four stages: data collection, data transmission, data processing and dissemination of information. However, despite this basic similarity, the very many networks existing in France are extremely varied in nature. At the national level, the bodies involved in epidemiological surveillance for infectious animal diseases are the Direction générale de l'alimentation, the Agence française de sécurité sanitaire des aliments and, to a lesser degree, the Institut français de recherche pour l'exploitation de la mer. In the field, the networks rely on the Direction des services vétérinaires, veterinary practitioners, laboratories in each département, and livestock producers' groups (especially animal health protection groups). Some twenty French networks currently in operation are presented in this article according to a classification based on published criteria. In the case of human infectious diseases, epidemiological surveillance is carried out almost entirely by the Direction générale de la santé and the Directions départementales d'action sanitaire et sociale, the Institut de veille sanitaire and the various Centres nationaux de référence (CNRs). Most human infectious diseases are monitored by one or more of the following broad categories of networks: reporting of notifiable diseases, the CNRs, the network of sentinel doctors, the network of hospital laboratories and departments, and medical causes of death. An example where surveillance is covered by several networks is also presented, namely surveillance for salmonellosis and Salmonella. Lastly, methods for evaluating networks are discussed.

    The purpose of this study was to describe the clinical and MR imaging features of acute gouty arthritis and to define the characteristic findings that would be helpful for differentiating acute gouty arthritis from septic arthritis. The authors retrospectively studied seven patients who suffered from acute gouty arthritis. The MR imaging findings were analyzed by two musculoskeletal radiologists who focused on joint effusion, subchondral bone erosion, bone marrow edema, synovial thickening (regular and even, or irregular and nodular), and the soft tissue changes (edema or abscess). The clinical records of the patients were reviewed with regard to age and gender, the clinical presentation and the laboratory findings (serum uric acid, WBC, erythrocyte sedimentation rate, C-reactive protein and synovial fluid culture). The patients consisted of six men and one woman whose mean age was 41 years (age range:24-65 years). The joints involved were the knee (n=6), and ankle (n=1). Two patients had medical histories of gouty attacks that involved the first metatarsophalangeal joint. In six cases, the serum uric acid level during acute attacks was elevated. In all the patients, the affected joint became swollen, hot, erythematous and extremely tender, and this was accompanied by a high ESR and a high C-reactive protein level at the time of presentation. The results of Gram stain and culture of the synovial fluid were negative. In all patients, the MR images showed large amounts of joint effusion, thick irregular and nodular synovial thickening and soft tissue edema without subchondral bone erosions and soft tissue abscess. In one case, subchondral bone marrow edema of the medial femoral condyle was present. In five cases, there were multiple low signal foci in the joint on the spin-echo T2-weighted MR image. Even though the MR imaging findings of acute gouty arthritis are nonspecific, it should be considered as a possible diagnosis when a large amount of joint effusion

    The practice of infectious diseases is an ever-changing discipline. Diseases such as syphilis and tuberculosis have been with mankind for millennia, whereas conditions such as AIDS and Zika virus are relatively new maladies. A working knowledge of clinical presentations associated with Zika virus infection, syphilis, and common parasitic infections will help the primary care provider determine whom to treat and whom to refer to a specialist. Increasing the use of vaccination for influenza and pre-exposure prophylaxis for HIV infection should reduce the burden of these common diseases. PMID:27621340

    Although Escherichia coli is among the most common causes of Gram-negative bacteraemia, infectious endocarditis (IE) due to this pathogen is rare. A 67-y-old male without a previous medical history presented with a new mitral regurgitation murmur and persisting E. coli bacteraemia in spite of broad......-spectrum intravenous antibiotics. Transthoracic and transoesophageal echocardiography revealed a severe mitral endocarditis. E. coli DNA was identified from the mitral valve and the vegetation, and no other pathogen was found. The case was further complicated by spondylodiscitis and bilateral endophthalmitis. Extra...

    Full Text Available OBJECTIVE: We evaluated the incidence of and the main risk factors associated with cutaneous adverse events in patients with chronic inflammatory arthritis following anti-TNF-α therapy. METHODS: A total of 257 patients with active arthritis who were taking TNF-α blockers, including 158 patients with rheumatoid arthritis, 87 with ankylosing spondylitis and 12 with psoriatic arthritis, were enrolled in a 5-year prospective analysis. Patients with overlapping or other rheumatic diseases were excluded. Anthropometric, socioeconomic, demographic and clinical data were evaluated, including the Disease Activity Score-28, Bath Ankylosing Spondylitis Disease Activity Index and Psoriasis Area Severity Index. Skin conditions were evaluated by two dermatology experts, and in doubtful cases, skin lesion biopsies were performed. Associations between adverse cutaneous events and clinical, demographic and epidemiological variables were determined using the chi-square test, and logistic regression analyses were performed to identify risk factors. The significance level was set at p<0.05. RESULTS: After 60 months of follow-up, 71 adverse events (73.85/1000 patient-years were observed, of which allergic and immune-mediated phenomena were the most frequent events, followed by infectious conditions involving bacterial (47.1%, parasitic (23.5%, fungal (20.6% and viral (8.8% agents. CONCLUSION: The skin is significantly affected by adverse reactions resulting from the use of TNF-α blockers, and the main risk factors for cutaneous events were advanced age, female sex, a diagnosis of rheumatoid arthritis, disease activity and the use of infliximab.

    Full Text Available Background: India is known to be endemic to numerous infectious diseases. The infectious disease profile of India is changing due to increased human environmental interactions, urbanisation and climate change. There are also predictions of explosive growth in infectious and zoonotic diseases. The Integrated Disease Surveillance Project (IDSP was implemented in Gujarat in 2004. Methods: We analysed IDSP data on seven laboratory confirmed infectious diseases from 2005–2011 on temporal and spatial trends and compared this to the National Health Profile (NHP data for the same period and with other literature. We chose laboratory cases data for Enteric fever, Cholera, Hepatitis, Dengue, Chikungunya, Measles and Diphtheria in the state since well designed vertical programs do not exist for these diseases. Statistical and GIS analysis was done using appropriate software. Results: Our analysis shows that the existing surveillance system in the state is predominantly reporting urban cases. There are wide variations among reported cases within the state with reports of Enteric fever and Measles being less than half of the national average, while Cholera, Viral Hepatitis and Dengue being nearly double. Conclusions: We found some limitations in the IDSP system with regard to the number of reporting units and cases in the background of a mixed health system with multiplicity of treatment providers and payment mechanisms. Despite these limitations, IDSP can be strengthened into a comprehensive surveillance system capable of tackling the challenge of reversing the endemicity of these diseases and preventing the emergence of others.

    Background: Increasing rates of HIV have been observed in women, African Americans, and Hispanics, particularly those residing in rural areas of the United States. Although cardiovascular (CV) complications in patients infected with human immunodeficiency virus (HIV) have significantly decreased following the introduction of antiretroviral therapy on a global scale, in many rural areas, residents face geographic, social, and cultural barriers that result in decreased access to care. Despite the advancements to combat the disease, many patients in these medically underserved areas are not linked to care, and fewer than half achieve viral suppression. Methods: Databases were systematically searched for peer-reviewed publications reporting infectious and non-infectious etiologies of cardiovascular disease in HIV-infected patients. Relevant articles cited in the retrieved publications were also reviewed for inclusion. Results: A variety of outcomes studies and literature reviews were included in the analysis. Relevant literature discussed the manifestations, diagnosis, treatment, and outcomes of infectious and non-infectious etiologies of cardiovascular disease in HIV-infected patients. Conclusion: In these medically underserved areas, it is vital that clinicians are knowledgeable in the manifestations, diagnosis, and treatment of CV complications in patients with untreated HIV. This review summarizes the epidemiology and causes of CV complications associated with untreated HIV and provide recommendations for management of these complications.
