    Chronic inflammation induced by biological, chemical and physical factors has been associated with increased risk of human cancer at various sites. Inflammation facilitates the initiation of normal cells and their growth and progression to malignancy through production of pro-inflammatory cytokines and diverse reactive oxygen and nitrogen species. These also activate signaling molecules involved in inflammation and carcinogenesis such as nuclear transcription factor (NF-{kappa}B), inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). Several chemopreventive agents act through inhibition of signaling pathways (e.g. NF-{kappa}B), inhibition of oxidant-generating enzymes (e.g. iNOS) and mediators of inflammation (e.g. COX-2), scavenging reactive oxygen and nitrogen species, and modulation of xenobiotic-metabolizing enzymes (especially phase II enzyme induction). Some anti-inflammatory drugs have been tested in clinical trials to prevent human cancer at several sites. Better understanding of the molecular mechanisms by which chronic inflammation increases cancer risk will lead to further development of new strategies for cancer prevention at many sites.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a demyelinating chronic neuropathy of immune origin whose diagnosis is based upon clinical, biological and electrophysiological data; previously critical to the diagnosis the nerve biopsy is now restricted to the rare situations where accurate diagnosis cannot be reached using these data alone. CIDP are mainly idiopathic, but a few associated diseases must be sought for as they require specific attention. Such associated diseases must particularly be discussed when the manifestations are severe or resistant to immunomodulating or immunosuppressive agents. Indeed, idiopathic CIDP are usually responsive to these treatments. The effectiveness of these treatments is limited by the importance of the secondary axonal loss. The dependence or the resistance may sometimes justify the association of several immunomodulating treatments. A single randomized controlled trial support the use of cytotoxic drugs and none with rituximab.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is the most common autoimmune neuropathy. The diagnosis depends on the clinical presentation with a progressive or relapsing course over at least 2 months and electrophysiological evidence of primary demyelination. Whereas typical CIDP is quite easily recognizable because virtually no other neuropathies present with both distal and proximal motor and sensory deficit, atypical CIDP, focal and multifocal variants in particular, may represent a difficult diagnostic challenge. CIDP very likely is an underdiagnosed condition as suggested also by a positive correlation between prevalence rates and sensitivity of electrophysiological criteria. Since no 'gold standard' diagnostic marker exists, electrophysiological criteria have been optimized to be at the same time as sensitive and as specific as possible. Additional supportive laboratory features, such as increased spinal fluid protein, MRI abnormalities of nerve segments, and in selected cases nerve biopsy lead to the correct diagnosis in the large majority of the cases. Objective clinical improvement following immune therapy is also a useful parameter to confirm the diagnosis. The pathogenesis and pathophysiology of CIDP remain poorly understood, but the available evidence for an inflammatory origin is quite convincing. Steroids, intravenous immunoglobulin (IVIG), and plasma exchange (PE) have been proven to be effective treatments. IVIG usually leads to rapid improvement, which is useful in severely disabled patients. Repeat treatment over regular time intervals for many years is often necessary. The effect of steroids is slower and the side-effect profile may be problematic, but they may induce disease remission more frequently than IVIG. An important and as of yet uncompletely resolved issue is the evaluation of long-term outcome to determine whether the disease is still active and responsive to treatment.

    Full Text Available Introduction: Inflammatory periodontal disease is one of the major concerns of researchers and clinicians, because it can lead to tooth loss and an increased risk of systemic pathologies, even at the age of 35. The purpose of this study was to determine the effects of gelatin-based probiotic consortium on the local and general factors of inflammation in rats with chronic periodontitis. Methods: The study object was a complex of probiotic bacteria based in an odourless 6% gelatin plate with neutral flavour. A cellular biomass of the consortium consists of following lactobacilli: Lactobacillus casei subsp. pseudoplantarum, Lactobacillus caseisubsp.casei, L.fermentum, and L. helveticus. The viable cell number was 2.5 x 109 CFU/ml. The model of chronic periodontitis was reproduced in the white random-bred rats that weighed 160-220g, by keeping them on a low-protein diet. After three months, symptoms associated with medium and severe chronic periodontitis were observed in the rats. Application was carried out on the oral mucosa of rats 1 time per day for 14 days. The stickers lacking consortium of microorganisms were used as the placebo. The "Solcoseril" gel was chosen as a comparator. The hematologic, biochemical, and morphological characteristics were investigated. Results: A complete clearance of periodontal pockets was observed during an objective examination of the experimental group rats on the 14th day of the experiment. Moreover, a gingival mucous turned pink, and there were no cyanosis tissues. The local changes were accompanied by improvement in hematological parameters, such as a reduction of blood eosinophilia and neutrophilia, and a recovery of the white blood cells number to the normal degree within the group that received the probiotic complex. A decrease of the acute plethora of microvasculature was observed morphologically as a result of the treatment. There were signs of basal layer activation of the stratified squamous epithelium

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

    The aetiology of chronic idiopathic intestinal inflammation is unknown. It is characterized by a diffuse infiltration with inflammatory cells into the intestinal mucosa and sometimes submucosa. Cats with chronic intermittent vomiting and diarrhoea, later on accompanied by anorexia and weight loss, are presented. Definitive diagnosis can be obtained by intestinal biopsy only. An immune pathogenesis is suspected, which is supported by the fact, that chronic inflammatory bowel disease responds to steroid therapy.

    Inflammation is a stereotypical physiological response to infections and tissue injury; it initiates pathogen killing as well as tissue repair processes and helps to restore homeostasis at infected or damaged sites. Acute inflammatory reactions are usually self-limiting and resolve rapidly, due to the involvement of negative feedback mechanisms. Thus, regulated inflammatory responses are essential to remain healthy and maintain homeostasis. However, inflammatory responses that fail to regulate themselves can become chronic and contribute to the perpetuation and progression of disease. Characteristics typical of chronic inflammatory responses underlying the pathophysiology of several disorders include loss of barrier function, responsiveness to a normally benign stimulus, infiltration of inflammatory cells into compartments where they are not normally found in such high numbers, and overproduction of oxidants, cytokines, chemokines, eicosanoids and matrix metalloproteinases. The levels of these mediators amplify the inflammatory response, are destructive and contribute to the clinical symptoms. Various dietary components including long chain omega-3 fatty acids, antioxidant vitamins, plant flavonoids, prebiotics and probiotics have the potential to modulate predisposition to chronic inflammatory conditions and may have a role in their therapy. These components act through a variety of mechanisms including decreasing inflammatory mediator production through effects on cell signaling and gene expression (omega-3 fatty acids, vitamin E, plant flavonoids), reducing the production of damaging oxidants (vitamin E and other antioxidants), and promoting gut barrier function and anti-inflammatory responses (prebiotics and probiotics). However, in general really strong evidence of benefit to human health through anti-inflammatory actions is lacking for most of these dietary components. Thus, further studies addressing efficacy in humans linked to studies providing greater

    Chronic progressive external ophthalmoplegia is one of mitochondrial disorders, characterized by ptosis, limitation of eye movement, variably severe bulbar muscle weakness and proximal limb weakness. Chronic progressive external ophthalmoplegia complicated with acquired disease is extremely rare. We report a 44 years old male patient with more than 20 years of chronic progressive bilateral ptosis and limitation of eye movements manifested dysarthria, dysphagia and neck muscle weakness for 3 years. The first muscle biopsy showed red-ragged fibers and cytochrome c oxidase negative fibers as well as inflammatory cells infiltration. Electron microscopy revealed paracrystalline inclusions. Mitochondrial genetic analysis demonstrated a large-scale mtDNA deletion of m.8470_13446del4977. The patient was treated with prednisone. In a three-year follow-up study, the second biopsy was performed. Before the treatment, except bilateral ptosis and external ophthalmopelgia, this patient presented bulbar muscle weakness and neck muscle weakness. After treated with prednisone, the symptoms of dysphagia, dysarthria and neck muscle weakness were significantly improved, and the second biopsy showed only mitochondrial myopathy pathology but the inflammations disappeared. Here, we report a patient with chronic progressive external ophthalmoplegia complicated with inflammatory myopathy and after treated with prednisone as myositis, he had a significant therapeutic effect.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a sporadically occurring, acquired neuropathic condition of autoimmune origin with chronic progressive or relapsing-remitting disease course. CIDP is a treatable disorder; a variety of immunosuppressive and immunomodulatory agents are available to modify, impede, and even reverse the neurological deficits and sequelae that manifest in the course of the disease. However, in many cases CIDP is not curable. Challenges that remain in the treatment of CIDP patients are well recognized and include a remarkably individual heterogeneity in terms of disease course and treatment response as well as a lack of objective and feasible measures to predict and monitor the responsiveness to the available therapies. In this chapter an overview of the currently used drugs in the treatment of CIDP patients is given and some important and controversial issues that arise in the context of care for CIDP patients are discussed.

    Chronic pancreatitis increases the risk of developingpancreatic cancer. This often presents as a mass lesionin the head of pancreas. Mass lesion in the head ofpancreas can also occur secondary to an inflammatorylesion. Recognising this is crucial to avoid unnecessarysurgery. This is sometimes difficult as there is an overlapin clinical presentation and conventional computedtomography (CT) abdomen findings in inflammatory andmalignant mass. Advances in imaging technologies likeendoscopic ultrasound in conjunction with techniqueslike fine needle aspiration, contrast enhancement andelastography as well as multidetector row CT, magneticresonance imaging and positron emission tomographyscanning have been shown to help in distinguishinginflammatory and malignant mass. Research is ongoingto develop molecular techniques to help characterisefocal pancreatic mass lesions. This paper reviews thecurrent status of imaging and molecular techniquesin differentiating a benign mass lesion in chronicpancreatitis and from malignancy.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired immune-mediated demyelinating neuropathy. In this report, we detail the course of a 58-year-old male patient who had headache and double vision followed by progressive paresthesia and difficulty in walking. The patient had bilateral papilledema and mild leg weakness, absent ankle jerks and loss of sensation in distal parts of his lower and upper extremities. His electromyography (EMG) was concordant with CIDP and lumbar puncture revealed high opening pressure. The polyradiculoneuropathy as well as the papilledema and elevated cerebrospinal fluid (CSF) pressure improved under steroids. The improvement in intracranial hypertension (IHT) and papilledema under steroid treatment suggests that the IHT in this patient might be associated with CIDP.

    Chronic inflammatory demyelinating polyneuropathy (CIDP) is characterized by an insidious onset showing progression over two months. However, up to 16% of CIDP patients may show acute presentation similar to Guillain-Barré syndrome (GBS). Such cases are termed acute-onset CIDP (A-CIDP). Distinguishing A-CIDP from GBS, especially the acute inflammatory demyelinating polyneuropathy (AIDP) subtype, is critical because therapeutic strategies and outcomes may differ between the two syndromes. Regarding clinical features, A-CIDP is less likely to have autonomic nervous system involvement, facial weakness, a preceding infectious illness, or the need for mechanical ventilation, in comparison with AIDP. Electrophysiological features are usually quite similar between the two, although follow-up studies may elucidate key differences. Around 8%-16% of GBS patients may show clinical deterioration shortly after improvement or stabilization following initial immunological therapy. Such a situation is termed treatment-related fluctuation (TRF; GBS-TRF). The distinction between GBS-TRF and A-CIDP is an important clinical issue because maintenance treatment is often required in CIDP. The diagnosis of A-CIDP should be considered when the condition of a patient with GBS deteriorates after nine weeks from onset, or when deterioration occurs three times or more.

    Full Text Available Alzheimer Disease (AD is a neurodegenerative disorder and the most common form of dementia. Histopathologically is characterized by the presence of two major hallmarks, the intracellular neurofibrillary tangles (NFTs and extracellular neuritic plaques (NPs surrounded by activated astrocytes and microglia. NFTs consist of paired helical filaments of truncated tau protein that is abnormally hyperphosphorylated. The main component in the NP is the amyloid-β peptide (Aβ, a small fragment of 40-42 amino acids with a molecular weight of 4kD. It has been proposed that the amyloid aggregates and microglia activation are able to favor the neurodegenerative process observed in AD patients. However, the role of inflammation in AD is controversial, because in early stages the inflammation could have a beneficial role in the pathology, since it has been thought that the microglia and astrocytes activated could be involved in Aβ clearance. Nevertheless the chronic activation of the microglia has been related with an increase of Aβ and possibly with tau phosphorylation. Studies in AD brains have shown an upregulation of complement molecules, pro-inflammatory cytokines, acute phase reactants and other inflammatory mediators that could contribute with the neurodegenerative process. Clinical trials and animal models with nonsteroidal anti-inflammatory drugs (NSAIDs indicate that these drugs may decrease the risk of developing AD and apparently reduce Aβ deposition. Finally, further studies are needed to determine whether treatment with anti-inflammatory strategies, may decrease the neurodegenerative process that affects these patients.

    Diseases associated with chronic inflammatory pathology claim a major share of worldwide deaths each year. A principal reason behind the huge number of casualties is associated with mild or unnoticed symptoms for long period of time since the outset, and that specific treatment options for these diseases have not yet emerged. Current anti-inflammatory drugs essentially have become ineffective for long term protection from these diseases as they also interfere with essential cellular pathways and associated toxicities. Notably, recent studies with a number of phytochemicals have shown promising results. These compounds isolated from various medicinal plants express their anti-inflammatory activities by down regulating expression of several crucial pro-inflammatory mediators. These are mostly antioxidants; inhibit induction of key transcription factors like nuclear factor kappa B (NF-κB) that are responsible for expression of proinflammatory mediators, and other growth regulators. Definitely, some of these compounds have the potential to be developed into new therapeutic agents to better control inflammation associated diseases in near future. This review summarizes recent findings on the molecular mechanisms through which various inflammatory activities are linked to disease progression and a group of natural products that have shown promise in controlling these processes.

    Objective To establish a smoke-induced chronic bronchitis rat model and evaluate the pathological change semi-quantitatively, and study the characteristics of the inflammatory cells in the bronchoalveolar lavage fluid (BALF) in various stages. Methods Chronic bronchitis sequential rat model was established by passively inhaling smoke mixture. Experiments were performed in 30 young male Sprague-Dawley rats, which comprised 5 groups in random, i.e.,4 chronic bronchitis model groups and I control group. After stained with hematoxylin and eosin, the specimens were studied by semi-quantitative method to evaluate the morphologic changes in various stages. Meanwhile, the inflammatory cells of the BALF and the activity of myeloperoxidase ( MPO ) of lung tissue were analysed. Results During the process of the chronic bronchitis, the pathologic score was increasing as time went on, and the typical morphologic changes of chronic bronchitis emerged in the group 7 weeks. The total number of inflammatory cells in BALF was increasing as time went on, correlated with the pathologic scores ( P < 0. 01 ).And the percentage of lymphocyte increased as well as positively correlated with pathologic scores ( P < 0. 05 ),whereas that of macrophage decreased and negatively correlated with pathologic scores (P <0. 05). The MPO lever of lung tissue was correlated with the pathologic scores ( P < 0. 01 ). But the percentage of the neutrophil in the BALF was just in a high level during the first week, then it maintained relatively lower. Conclusion Smoke-induced chronic bronchitis is a slowly progressive inflammation process. The model we established is convenient and simple for the longitudinal study on the inflammatory process of chronic bronchitis and the therapy in the early stage. The semi-quantitative evaluation for the pathological change is with much more value. During the inflammatory sequential process of early stage of chronic bronchitis, the cellular characteristics are

    Crohn's disease (CD) is a chronic inflammatory disorder of the gastrointestinal tract that is frequently accompanied by systemic complications. Neuropathologies have not been well investigated as extraintestinal manifestations of CD. We herein report the case of a 36-year-old man with CD who presented with progressive weakness and numbness. A neurological examination and the results of a nerve conduction study and a sural nerve biopsy led to a diagnosis of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). Plasma exchanges were initially effective; however, the effects gradually declined starting 10 days after the plasma exchange (PE). These results suggest that humoral factors may play an important role in CIDP associated with CD.

    Full Text Available Long-term therapy with the macrolide antibiotic erythromycin was shown to alter the clinical course of diffuse panbronchiolitis in the late 1980s. Since that time, macrolides have been found to have a large number of anti-inflammatory properties in addition to being antimicrobials. These observations provided the rationale for many studies performed to assess the usefulness of macrolides in other inflammatory diseases including skin and hair disorders, such as rosacea, psoriasis, pityriasis rosea, alopecia areata, bullous pemphigoid, and pityriasis lichenoides. This paper summarizes a collection of clinical studies and case reports dealing with the potential benefits of macrolides antibiotics in the treatment of selected dermatoses which have primarily been classified as noninfectious and demonstrating their potential for being disease-modifying agents.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is the most common treatable chronic autoimmune neuropathy. Multiple diagnostic criteria have been established, with the primary goal of identifying neurophysiologic hallmarks of acquired demyelination. Treatment modalities have expanded to include numerous immunomodulatory therapies, although the best evidence continues to be for corticosteroids, plasma exchange, and intravenous immunoglobulin (IVIg). This review describes the pathology, epidemiology, pathogenesis, diagnosis, and treatment of CIDP.

    Despite recent advancements in the treatment of coronary artery disease (CAD), it remains the number one cause of death in the world. While traditional risk factors partially account for the development of CAD, other novel risk factors have recently been implicated. Specifically, chronic inflammation has been postulated to play a role in the development and propagation of this disease. The purpose of this systematic review is to examine the available evidence to determine if patients with chronic inflammatory diseases have higher rates of cardiovascular disease. A MEDLINE search was conducted for articles published between 1980-2009. We focused on studies that assessed hard cardiovascular endpoints in subjects with chronic inflammatory conditions such as systemic lupus erythematosus, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, polymyositis/dermatomyositis, and inflammatory bowel disease. Although largely based on small studies, our review indicates that patients with chronic inflammatory conditions are likely at elevated risk for the development of CAD. Further research consisting of prospective cohort studies is needed to better quantify this risk.

    Full Text Available Background: The Chronic Inflammatory Periodontal Disease is related with multiple risk factors. Those patients with human immunodeficiency virus have higher risk of presenting this disease and it is usually more serious in these cases. Objective: To describe the prevalence of Chronic Inflammatory Periodontal Disease in patients with HIV. Methods: Descriptive, observational, cross-sectional study including patients with HIV in Sancti Spiritus province. The occurrence of the disease was determined after the Periodontics Cuban Standards, and oral hygiene was assessed through the simplified oral hygiene index. Other variables were measured, such as smoking habits, T CD4+ lymphocyte counting and virus load. The independent association of each risk factor with the disease was determined through a logistic regression model. Results: The 56, 5 % of the 154 patients presented Chronic Inflammatory Periodontal Disease; 60 (39.0% gingivitis and 27 (17,5% periodontitis. Gingivitis was associated with poor oral hygiene (OR: 3,71 and periodontitis with smoking habit (OR: 5,20. The severe forms of periodontitis occurred mainly in patients with lymphocyte counting lower than 500 cells/mm3 . Conclusions: The prevalence of Chronic Inflammatory Periodontal Disease in patients with HIV in Sancti Spiritus province is linked to known risk factors such as smoking habits and oral hygiene.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an inflammatory neuropathy, classically characterised by a slowly progressive onset and symmetrical, sensorimotor involvement. However, there are many phenotypic variants, suggesting that CIDP may not be a discrete disease entity but rather a spectrum of related conditions. While the abiding theory of CIDP pathogenesis is that cell-mediated and humoral mechanisms act together in an aberrant immune response to cause damage to peripheral nerves, the relative contributions of T cell and autoantibody responses remain largely undefined. In animal models of spontaneous inflammatory neuropathy, T cell responses to defined myelin antigens are responsible. In other human inflammatory neuropathies, there is evidence of antibody responses to Schwann cell, compact myelin or nodal antigens. In this review, the roles of the cellular and humoral immune systems in the pathogenesis of CIDP will be discussed. In time, it is anticipated that delineation of clinical phenotypes and the underlying disease mechanisms might help guide diagnostic and individualised treatment strategies for CIDP.

    CIDP is autoimmune-associated peripheral neuropathy characterized by motor and sensory disturbances in each limb. While various phenotypes have been reported in CIDP, the essential pathogenesis is not elucidated yet. Clinicopathological study indicated axonal dysfunction (muscle atrophy and decreased compound muscular action potentials) is one of the most important factors in IVIg Non-responders. Furthermore, single nucleotide polymorphism (SNP) haplotype/diplotype analysis within a linkage disequilibrium block indicates transient axonal glycoprotein 1 (TAG-1), which controls proper distribution of potassium channels in juxtaparanode, is an important factor for IVIg responsiveness. Gene expression analysis of biopsied nerves supported the hypothesis that CIDP pathogenesis is involved in humoral and cellular immune system. With respect to IVIg responsiveness, expression profiles indicate whole CIDP patients need conventional immune-modulating therapies in somewhat, while we should re-consider how to use them. From aspects of gene expression results, Non-responders need not only conventional immune-modulating therapies but also other original modalities which could intervene the pathogenesis except Schwann/inflammatory cells while Responders with IVIg dependence should need stronger and longer immune-suppression.

    To determine the relationship between H. pylori density with severity of chronic inflammatory infiltrate. Study Design: A cross-sectional study. Place and Duration of Study: The study was carried out in the Department of Pathology (Histopathology), Army Medical College, National University of Sciences and Technology (NUST) Islamabad, from Nov 2011 to Nov 2012. Methodology: Gastric antral biopsies of H. pylori associated chronic gastritis were included in the study. Demographic characteristics and relevant clinical information were collected. First hundred biopsies of H. pylori associated chronic gastritis were assessed for density of H. pylori and chronic inflammatory infiltrate. istopathological features like lymphoid aggregates, ulcer slough, superficial epithelial damage, dysplasia and nuclear reactive changes were simply assessed in case of their presence or absence. Results: A significant moderate positive correlation was found between grades of H. pylori and chronic inflammatory infiltrate (rs= 0.636). Insignificant correlation was found with lymphoid aggregates, superficial epithelial damage, dysplasia and nuclear reactive changes. Conclusion: In conclusion this study corroborated the determination of histopathological parameters and depicted that, the greater the density of H. pylori infection, the greater the degrees of chronic inflammatory infiltrate.

    2010-06-01

    MicroRNAs (miRNAs) are the non-coding RNAs that act as post-translational regulators to their complimentary messenger RNAs (mRNA). Due to their specific gene silencing property, miRNAs have been implicated in a number of cellular and developmental processes. Also, it has been proposed that a particular set of miRNA spectrum is expressed only in a particular type of tissue. Many interesting findings related to the differential expression of miRNAs in various human diseases including several types of cancers, neurodegenerative diseases and metabolic diseases have been reported. Deregulation of miRNA expression in different types of human diseases and the roles various miRNAs play as tumour suppressors as well as oncogenes, suggest their contribution to cancer and/or in other disease development. These findings have possible implications in the development of diagnostics and/or therapeutics in human malignancies. In this review, we discuss various miRNAs that are differentially expressed in human chronic inflammatory diseases, neurodegenerative diseases, cancer and the further prospective development of miRNA based diagnostics and therapeutics.

    2016-02-01

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a chronic immune-mediated neuropathy: it is clinically heterogeneous (relapsing-remitting form, chronic progressive form, monophasic form or CIDP having a Guillain-Barré syndrome-like onset), but potentially treatable. Although its pathophysiology remains largely unknown, CIDP is considered an immune-mediated neuropathy. Therefore, many immunotherapies have been proposed in this peripheral nervous system disorder, the most known efficient treatments being intravenous immunoglobulin, corticosteroids and plasma exchange. However, these therapies remain unsatisfactory for many patients, so numerous other immunotherapeutic strategies have been evaluated, based on their immunosuppressant or immunomodulatory potency. We have performed a large review of the literature about treatment in CIDP, with a special emphasis on novel and alternative immunotherapeutic strategies. PMID:26809024

    Bronchial asthma and chronic obstructive pulmonary disease (COPD), as chronic airway inflammatory diseases, seriously threaten the health of human beings. Chinese medicine has obvious advantages in prevention and treatment of them. "Preventive treatment theory" is a sort summarization of preventive medicine in Chinese medicine. The theory is not only reflected at the disease prevention levels, also embodied in the active treatment and the rehabilitation process. It was especially deep and colorfully embodied in the prevention and treatment of chronic airway inflammatory diseases such as asthma and COPD. In this paper,clarified were the prevention and treatment targets, ways of thinking and methods in different stages of asthma and COPD from various viewpoints including prevention before disease occurrence, treating disease at disease onset, preventing the aggravation once disease occurs, and consolidation after disease occurs. We hope to improve ways of thinking and prevention and treatment levels of bronchial asthma and COPD by Chinese medicine. PMID:24063226

  9. Managing Inflammatory Manifestations in Patients with Chronic Granulomatous Disease.

    Science.gov (United States)

    2016-10-01

    Chronic granulomatous disease (CGD) is a primary immunodeficiency caused by lack of phagocyte nicotinamide adenine dinucleotide phosphate (NADPH) oxidase, which results in inflammatory dysregulation and increased susceptibility to infections. Patients with CGD may develop severe obstructive disorders of the digestive tract as a result of their dysregulated inflammatory response. Despite a growing focus on inflammatory manifestations in CGD, the literature data on obstructive complications are far less extensive than those on infectious complications. Diagnosis and management of patients with concomitant predispositions to infections and hyperinflammation are particularly challenging. Although the inflammatory and granulomatous manifestations of CGD usually respond rapidly to steroid treatment, second-line therapies (immunosuppressants and biologics) may be required in refractory cases. Indeed, immunosuppressants (such as anti-tumor necrosis factor agents, thalidomide, and anakinra) have shown some efficacy, but the value of this approach is controversial, given the questionable risk-to-benefit ratio and the small numbers of patients treated to date. Significant progress in allogeneic hematopoietic stem cell transplantation (the only curative treatment for CGD) has been made through better supportive care and implementation of improved, reduced-intensity conditioning regimens. Gene therapy may eventually be an option for patients lacking a suitable donor; clinical trials with new, safer vectors are ongoing at a few centers. PMID:27299584

    Since the first description of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) by PJ Dyck's group at the Mayo Clinic 35 years ago, a wide range of publications have underlined the clinical, electrophysiologic and histopathologic heterogeneity of this disease. Expert consensus opinion is that CIDP should be considered in any patient with progressive symmetrical or asymmetrical polyradiculoneuropathy whose clinical course is relapsing and remitting or progresses for more than two months, especially if there are positive sensory symptoms, proximal weakness, are flexia without wasting, or preferential loss of vibration or joint-position sense. Electrophysiologic features of demyelinating polyneuropathy (especially conduction blocks) and elevated protein levels in cerebrospinal fluid may assist with the diagnosis. However, various clinical pictures have been described in patients with CIDP including pure motor or sensory impairment, and distal, multifocal or focal distribution. Two specific points have recently been emphasized:--while most CIDP patients have chronic onset, acute onset resembling Guillain-Barré syndrome may sometimes occur;--pure sensory forms may require different diagnostic strategies, including the use of somatosensory evoked potentials showing abnormal proximal sensory conduction, and nerve biopsy showing macrophage-associated demyelination, onion bulb formation, demyelinated and partially remyelinated nerve fibres, endoneurial edema, endoneurial mononuclear cell infiltration, and variation between fascicles. Several sets of diagnostic criteria for CIDP have been proposed, with different sensitivities and specificities. The European Federation of Neurological Societies/Peripheral Nerve Society criteria strike a balance between specificity, which needs to be higher for research purposes than for clinical diagnosis, and sensitivity, which, if too low, might lead to some cases being missed. CIDP patients may have a variety of

    Sarah Bernhardt had a recurrent and later persistent inflammatory arthritis of her right knee for more than 25 years. She probably had pulmonary tuberculosis, starting a dozen years before the arthritis, and her chronic synovitis may have been tuberculous. Several months in a cast led to deterioration and later amputation of the leg, an outcome that might have been prevented by surgical arthrodesis. Despite the loss of her limb and progressive renal failure, she continued an active theatrical career until her death at age 78. PMID:17043454

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an autoimmune disorder characterized by patchy demyelination of nerve roots and distal nerves. The course may be monophasic progressive or relapsing-remitting. CIDP is less common in children than in adults. As in adults, children with CIDP present with proximal and distal weakness and loss of deep tendon reflexes. Children are most often brought to medical attention due to gait disturbance and falling. As in adults, immunomodulatory treatment is the mainstay of therapy. Based on the small number of case series available, children with CIDP seem have a more favorable long-term course than adults.

    We present characteristic magnetic resonance imaging (MRI) features in a pediatric female patient with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). Muscle weakness developed at 8 years old and fluctuated during the clinical course over 7 years. Electrophysiological studies showed a demyelination pattern with moderately delayed nerve conduction velocity, as well as dispersion phenomenon. MRI showed marked changes in thickening of the spinal nerve roots and their peripheral nerves in the lumber and brachial plexuses, as well as in the bilateral trigeminal nerves. It is suggested that these MRI features are characteristic and strongly supportive of the diagnosis of CIDP with a prolonged clinical course.

    The human body is exposed to a multitude of microbes and infectious organisms throughout life. Many of these organisms colonise the skin, gastrointestinal tract (GIT) and airway. We now recognise that this colonisation includes the lower airway, previously thought to be sterile. These colonising organisms play an important role in disease prevention, including an array of chronic inflammatory conditions that are unrelated to infectious diseases. However, new evidence of immune dysregulation suggests that early colonisation, especially of the GITand airway, by pathogenic micro-organisms, has deleterious effects that may contribute to the potential to induce chronic inflammation in young children, which may only express itself in adult life.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a chronically progressing or relapsing disease caused by immune-mediated peripheral neuropathy. We report the anesthetic management of three CIDP patients who underwent elective orthopedic surgeries. Owing to the risk of neuraxial anesthetics triggering demyelination, general anesthesia was selected to avoid epidural or spinal anesthesia or other neuraxial blockade. It was also judged prudent to avoid prolonged perioperative immobilization, which might compress vulnerable peripheral nerves. For Patient 1, general anesthesia was induced with propofol, remifentanil, and sevoflurane, and was maintained with sevoflurane and remifentanil. For Patients 2 and 3, general anesthesia was induced and maintained with propofol and remifentanil. For tracheal intubation, under careful monitoring with peripheral nerve stimulators, minimal doses of rocuronium (0.6-0.7 mg x kg(-1)) were administered. When sugammadex was administered to reverse the effect of rocuronium, all patients rapidly regained muscular strength. Postoperative courses were satisfactory without sequelae.

    The process of implantation is highly complex and involves a delicate interplay between the embryo and the appropriate maternal environment. The failure to implant is thought to be due to maternal factors or embryonic factors. Inflammation can be a part of the normal physiologic process during implantation; however, there are also pathologic entities that adversely affect uterine receptivity. This review will focus on chronic endometritis and hydrosalpinges as two specific inflammatory processes that contribute to implantation failure. For both chronic endometritis and hydrosalpinges, we will review the diagnosis, pathophysiology, and effect on implantation following treatment. The existing literature conclusively demonstrates that hydrosalpinges should be addressed by either laparoscopic salpingectomy or proximal tubal occlusion prior to in vitro fertilization. The picture for chronic endometritis is less clear since the diagnosis and treatment of chronic endometritis are not standardized, and there are no available randomized controlled trials on this topic. Future studies may target gene expression arrays as a method for further elucidating the role of inflammatory markers in normal and abnormal implantation processes. PMID:26132934

    The prokaryotic and eukaryotic cells of the colon exist in a highly complex, but harmonious relationship.Disturbances in this remarkable symbiosis can result in the development of inflammatory bowel diseases (IBD).Although the etiology of IBD is not entirely understood,it is known that the chronic inflammation of Crohn's disease, ulcerative colitis and chronic pouchitis are a result of an overly aggressive immune response to the commensal intestinal flora in genetically susceptible hosts. Recent studies have enhanced our ability to understand the interaction between the host and its intestinal microflora and the role the microflora plays in maintaining intestinal homeostasis. As we begin to understand the benefits conferred to the intestine by the microflora, the notion of modifying the composition of the bacterial load to improve human health has arisen.A significant body of research now exists investigating the role of probiotics and prebiotics in ameliorating chronic intestinal inflammation. This article will begin with an overview of the role of the commensal microflora in maintaining mucosal immune homeostasis, and how a dysregulated immune response to the intestinal microflora results in IBD. This will be followed by a summary of the use of probiotics and prebiotics in experimental and human IBD.

    Chronic inflammatory bowel disease is diagnosed and monitored by the combination of colonoscopy and small bowel enteroklysis. Magnetic resonance imaging has become the gold standard for the imaging of perirectal and pelvic fistulas. With the advent of ultrafast MRI small and large bowel imaging has become highly attractive and is being advocated more and more in the diagnostic work up of inflammatory bowel disease. Imaging protocols include fast T{sub 1}-weighted gradient echo and T{sub 2}-weighted TSE sequences and oral or rectal bowel distension. Furthermore, dedicated imaging protocols are based on breath-hold imaging under pharmacological bowel paralysis and gastrointestinal MR contrast agents (Hydro-MRI). High diagnostic accuracy can be achieved in Crohn's disease with special reference to the pattern of disease, depth of inflammation, mesenteric reaction, sinus tract depiction and formation of abscess. In ulcerative colitis, the mucosa-related inflammation causes significantly less bowel wall thickening compared to Crohn's disease. Therefore with MRI, the extent of inflammatory changes is always underestimated compared to colonoscopy. According to our experience in more than 200 patients as well as the results in other centers, Hydro-MRI possesses the potential to replace enteroklysis in the diagnosis of chronic inflammatory bowel disease and most of the follow-up colonoscopies in Crohn's disease. Further technical improvements in 3D imaging will allow interactive postprocessing of the MR data. (orig.)

    Full Text Available In healthy individuals billions of cells die by apoptosis every day. Removal of the dead cells by phagocytosis (a process called efferocytosis must be efficient to prevent secondary necrosis and the consequent release of proinflammatory cell contents that damages the tissue environment and provokes autoimmunity. In addition, detection and removal of apoptotic cells generally induces an anti-inflammatory response. As a consequence improper clearance of apoptotic cells, being the result of either genetic anomalies and /or a persistent disease state, contributes to the establishment and progression of a number of human chronic inflammatory diseases such as autoimmune and neurological disorders, inflammatory lung diseases, obesity, type 2 diabetes or atherosclerosis. During the past decade our knowledge about the mechanism of efferocytosis has significantly increased, providing therapeutic targets through which impaired phagocytosis of apoptotic cells and the consequent inflammation could be influenced in these diseases.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired disease that may affect nerve roots and peripheral nerves. Despite its low incidence, diagnosis is particularly important because there are different effective treatments. Human immunoglobulin is one of the mainstays of the treatment. Although there are few studies up to date, subcutaneous immunoglobulin (IgSC) has been proposed as an alternative to intravenous administration with similar efficacy. We present three cases with definite CIDP, classified according to the European Federation of Neurological Societies / Peripheral Nerve, Society (EFNS /PNS) criteria in which was used SCIgG as a treatment after success with the intravenous route. The Overall Neuropathy Limitations Scale (ONLS) was used to estimate the changes in the muscular strength before and after treatment. PMID:26826992

    Full Text Available Various forms of neuropathy are seen diabetic patients; chronic inflammatory demyelinating polyneuropathy (CIDP seems not to be infrequent neuropathy in patients suffering from diabetes and it seems to be more common than in the general population; on the contrary, some authorities do not support pathogenetic association between diabetes mellitus (DM and CIDP. Also, there are some controversies on the subject of CIDP treatment in diabetic patients. Some studies showed that patients with CIDP-DM considerably had recovered following treatment with immunotherapeutic modalities like (Intravenous immunoglobulin IVIG and conversely, some else have argued against the prescription of IVIG in this group and recommend treatment with corticosteroids and provided that resistant, rituximab may be beneficial. The main limitation in most studies is the inadequate number of cases and as a result, problematic decision making in treatment. This article represents an inclusive review of diabetic CIDP presentation and treatment.

    Immunoglobulins are an effective but expensive treatment for chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). Although the goal is to improve function, use of functional scales to monitor therapy is not widespread. Limited recent evidence suggests that doses lower than those used traditionally may be as effective. There are no proven correlations of effective dose with weight, disease severity, or duration. The clinical course of CIDP is heterogeneous and includes monophasic forms and complete remissions. Careful monitoring of immunoglobulin use is necessary to avoid overtreatment. Definitive evidence for immunoglobulin superiority over steroids is lacking. Although latest trial evidence favors immunoglobulins over steroids, the latter may result in higher remission rates and longer remission periods. This article addresses the appropriateness of first-line, high-dose immunoglobulin treatment for CIDP and reviews important clinical questions regarding the need for long-term therapy protocols, adequate monitoring, treatment withdrawal, and consideration of corticosteroids as an alternative to immunoglobulin therapy.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and its variants can be challenging to diagnose and treat. A combination of clinical, electrophysiological and laboratory features is often required to reach a diagnosis. New data are emerging about potential biomarkers and factors that may indicate treatment needs in individual patients. High-quality evidence exists for the efficacy of intravenous immunoglobulin (IVIG) in the treatment of CIDP, including quality of life (QoL) benefits. Besides pharmacological treatment, psychological factors must also be addressed to improve patients' QoL. Home-based IVIG infusion therapy is currently a well-established approach in some countries. A 6-month pilot study conducted in Ontario, Canada, provided proof of safety and patient acceptance of home-based IVIG therapy, although some logistical issues emerged.

    Chantal eKeijzer

    2013-08-01

    Full Text Available Many existing therapies in autoimmune diseases are based on systemic suppression of inflammation, the observed side effects illustrate the need for more specific interventions. Regulatory T cells (Treg are pivotal controllers of (autoaggressive immune responses, and decreased Treg numbers and/or functioning have been associated with autoimmune disease. Especially antigen-specific targeting of Treg would enable tailor made interventions, while obviating negative side effects of general immuno-suppression. Self-antigens that participate in inflammation, irrespective of the etiology of the different autoimmune diseases, are held to be candidate antigens for such interventions. Rather than tolerance induction to disease inciting self-antigens, which are frequently unknown, general self-antigens expressed at sites of inflammation would allow targeting of disease independent, but inflammatory-site specific, regulatory mechanisms. Preferably, such self-antigens should be abundantly expressed and up-regulated at the inflammatory site. Heat shock proteins show several of these characteristics.The development of antigen-specific Treg inducing vaccines is a major novel goal in the field of immunotherapy in autoimmune diseases. Progress is hampered by the lack of effective antigens and by the fact that other factors such as dose, route and the presence or absence of an adjuvant, turned out to be critical unknowns, with respect to effective induction of Treg. The use of a Treg inducing adjuvant might be required to achieve effective regulatory responses, in the case of ongoing inflammation. Future goals will be the optimization of natural Treg expansion (or the induction of adaptive Treg without loss of their suppressive function or the concomitant induction of non-regulatory T cells. Here, we discuss the potential use of protein/peptide-based vaccines combined with Treg inducing adjuvants for the development of therapeutic vaccines against chronic

  11. SPECT radiopharmaceuticals for imaging chronic inflammatory diseases in the last decade

    International Nuclear Information System (INIS)

    In the recent years, many radiopharmaceuticals have been described for the diagnosis of inflammatory chronic diseases. Several peptides, receptor ligands and monoclonal antibodies have been radiolabelled, allowing in-vivo visualization of inflammatory processes at a cellular and molecular level. The labelling of cytokines such as interleukin-1, interleukin-2, interleukin-12 and MCP-1 has facilitated the identification of inflamed synovia in patients with rheumatoid arthritis, active Crohn’s disease, vulnerable atherosclerotic plaques and other targets. The possibility of using monoclonal antibodies against TNF-α, CD2, CD3, CD4 and anti-selectin has not only allowed the localization of inflamed sites but had also a significant impact in helping the selection of patients who can benefit from biological therapies. Regarding radiolabelled peptides, it is important to highlight the increasing use of somatostatin analogues targeting somatostatin receptors in inflammatory diseases, particularly for rheumatoid arthritis, Sjögren syndrome and autoimmune thyroid diseases. In the present review we describe the state of the art of SPECT radiopharmaceuticals to image chronic inflammatory diseases.

    2014-05-01

    Full Text Available Neuropsychiatric symptoms are frequent in obesity. In addition to their substantial economic and health impact, these symptoms significantly interfere with the quality of life and social function of obese individuals. While the pathophysiological mechanisms underlying obesity-related neuropsychiatric symptoms are still under investigation and remain to be clearly identified, there is increasing evidence for a role of inflammatory processes. Obesity is characterized by a chronic low-grade inflammatory state that is likely to influence neuropsychiatric status given the well-known and highly documented effects of inflammation on brain activity/function and behavior. This hypothesis is supported by recent findings emanating from clinical investigations in obese subjects and from experimentations conducted in animal models of obesity. These studies converge to show that obesity-related inflammatory processes, originating either from the adipose tissue or gut microbiota environment, spread to the brain where they lead to substantial changes in neurocircuitry, neuroendocrine activity, neurotransmitter metabolism and activity, and neurogenesis. Together, these alterations contribute to shape the propitious bases for the development of obesity-related neuropsychiatric comorbidities.

    Conti, Pio; Shaik-Dasthagirisaeb, Yazdami

    2015-01-01

    Inflammation is a process that plays an important role in the initiation and progression of atherosclerosis and immune disease, involving multiple cell types, including macrophages, T-lymphocytes, endothelial cells, smooth muscle cells and mast cells. The fundamental damage of atherosclerosis is the atheromatous or fibro-fatty plaque which is a lesion that causes several diseases. In atherosclerosis the innate immune response, which involves macrophages, is initiated by the arterial endothelial cells which respond to modified lipoproteins and lead to Th1 cell subset activation and generation of inflammatory cytokines and chemoattractant chemokines. Other immune cells, such as CD4+ T inflammatory cells, which play a critical role in the development and progression of atherosclerosis, and regulatory T cells [Treg], which have a protective effect on the development of atherosclerosis are involved. Considerable evidence indicates that mast cells and their products play a key role in inflammation and atherosclerosis. Activated mast cells can have detrimental effects, provoking matrix degradation, apoptosis, and enhancement as well as recruitment of inflammatory cells, which actively contributes to atherosclerosis and plaque formation. Here we discuss the relationship between atherosclerosis, inflammation and mast cells. PMID:26648785

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

    2015-01-01

    Background Chronic inflammatory diseases (CID) are globally highly prevalent and characterized by severe pathological medical conditions. Several trials were conducted aiming at measuring the effects of manipulative therapies on patients affected by CID. The purpose of this review was to explore the extent to which osteopathic manipulative treatment (OMT) can be benefi-cial in medical conditions also classified as CID. Methods This review included any type of experimental study which enrolled sub-jects with CID comparing OMT with any type of control procedure. The search was conducted on eight databases in January 2014 using a pragmatic literature search approach. Two independent re-viewers conducted study selection and data extraction for each study. The risk of bias was evaluated according to the Cochrane methods. Heterogeneity was assessed and meta-analysis performed where possible. Results 10 studies met the inclusion criteria for this review enrolling 386 subjects. The search identified six RCTs, one laboratory study, one cross-over pilot studies, one observation-al study and one case control pilot study. Results suggest a potential effect of osteopathic medicine on patients with medical pathologies associated with CID (in particular Chronic Obstructive Pul-monary Disease (COPD), Irritable Bowel Syndrome, Asthma and Peripheral Arterial Disease) com-pared to no treatment or sham therapy although data remain elusive. Moreover one study showed possible effects on arthritis rat model. Meta-analysis was performed for COPD studies only show-ing no effect of any type of OMT applied versus control. No major side effects were reported by those receiving OMT. Conclusion The present systematic review showed inconsistent data on the effect of OMT in the treatment of medical conditions potentially associated with CID, however the OMT appears to be a safe approach. Further more robust trials are needed to determine the direction and magnitude of the effect of OMT and to

The purpose of this review was to explore the extent to which osteopathic manipulative treatment (OMT can be benefi-cial in medical conditions also classified as CID.This review included any type of experimental study which enrolled sub-jects with CID comparing OMT with any type of control procedure. The search was conducted on eight databases in January 2014 using a pragmatic literature search approach. Two independent re-viewers conducted study selection and data extraction for each study. The risk of bias was evaluated according to the Cochrane methods. Heterogeneity was assessed and meta-analysis performed where possible.10 studies met the inclusion criteria for this review enrolling 386 subjects. The search identified six RCTs, one laboratory study, one cross-over pilot studies, one observation-al study and one case control pilot study. Results suggest a potential effect of osteopathic medicine on patients with medical pathologies associated with CID (in particular Chronic Obstructive Pul-monary Disease (COPD, Irritable Bowel Syndrome, Asthma and Peripheral Arterial Disease com-pared to no treatment or sham therapy although data remain elusive. Moreover one study showed possible effects on arthritis rat model. Meta-analysis was performed for COPD studies only show-ing no effect of any type of OMT applied versus control. No major side effects were reported by those receiving OMT.The present systematic review showed inconsistent data on the effect of OMT in the treatment of medical conditions potentially associated with CID, however the OMT appears to be a safe approach. Further more robust trials are needed to determine the direction and magnitude of the effect of OMT and to generalize favorable results.

    Chronic obstructive pulmonary disease (COPD) is associated with chronic inflammation affecting predominantly the lung parenchyma and peripheral airways that results in largely irreversible and progressive airflow limitation. This inflammation is characterized by increased numbers of alveolar macrophages, neutrophils, T lymphocytes (predominantly TC1, TH1, and TH17 cells), and innate lymphoid cells recruited from the circulation. These cells and structural cells, including epithelial and endothelial cells and fibroblasts, secrete a variety of proinflammatory mediators, including cytokines, chemokines, growth factors, and lipid mediators. Although most patients with COPD have a predominantly neutrophilic inflammation, some have an increase in eosinophil counts, which might be orchestrated by TH2 cells and type 2 innate lymphoid cells though release of IL-33 from epithelial cells. These patients might be more responsive to corticosteroids and bronchodilators. Oxidative stress plays a key role in driving COPD-related inflammation, even in ex-smokers, and might result in activation of the proinflammatory transcription factor nuclear factor κB (NF-κB), impaired antiprotease defenses, DNA damage, cellular senescence, autoantibody generation, and corticosteroid resistance though inactivation of histone deacetylase 2. Systemic inflammation is also found in patients with COPD and can worsen comorbidities, such as cardiovascular diseases, diabetes, and osteoporosis. Accelerated aging in the lungs of patients with COPD can also generate inflammatory protein release from senescent cells in the lung. In the future, it will be important to recognize phenotypes of patients with optimal responses to more specific therapies, and development of biomarkers that identify the therapeutic phenotypes will be important.

    Conclusion Serum hepcidin levels were associated with iron status and inflammation in maintenance hemodialysis patients, and the high hepcidin serum levels, found in hemodialysis (HD patients, are dependent on the magnitude of the inflammatory process and on recombinant human erythropoietin doses. Hepcidin and its regulatory pathways are potential therapeutic targets, which could lead to effective treatment of anemia in chronic hemodialysis.

  1. Sonography in the diagnosis of chronic inflammatory bowel disease

    International Nuclear Information System (INIS)

    The accuracy of ultrasonography (US) in diagnosing active inflammatory bowel disease (IBD) is assessed on the basis of a randomized prospective study of 61 patients. Twenty-six of the patients were affected with crohn's disease (CD) and 12 with ulcerative colitis, while the remaining 23 patients were control subjects with no specific chronic IBD. The US signs considered as a significant for active CD and UC were: -visualization of a typical target image, that is a hyperechoic center corresponding to luminal bowel content, surrounded by a hypoechoic ring corresponding to loop walls; -at least 2 of the following: solid abdominal mass, distended loops, luminal narrowing, reduced peristalsis, stiff loops, and accumulation of fluid between the loops. US sensitivity and specificity for CD were 77% and 95.6%, respectively. As for UC, no significant results were obtained. In our experiance, US is a reliable method for detecting alterations and, especially, comlpications typical of CD in its active phase. Considering the young age of patients affected with CD and the number of exams they must undergo, US is considered as a useful tool in disease follow-up

    Full Text Available Polyneuropathy leads to postural instability and an increased risk of falling. We investigated how impaired motor impairment and proprioceptive input due to neuropathy influences postural strategies.Platformless bisegmental posturography data were recorded in healthy subjects and patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP. Each subject stood on the floor, wore a head and a hip electromagnetic tracker. Sway amplitude and velocity were recorded and the mean direction difference (MDD in the velocity vector between trackers was calculated as a flexibility index.Head and hip postural sway increased more in patients with CIDP than in healthy controls. MDD values reflecting hip strategies also increased more in patients than in controls. In the eyes closed condition MDD values in healthy subjects decreased but in patients remained unchanged.Sensori-motor impairment changes the balance between postural strategies that patients adopt to maintain upright quiet stance. Motor impairment leads to hip postural strategy overweight (eyes open, and prevents strategy re-balancing when the sensory context predominantly relies on proprioceptive input (eyes closed.

    Objective To investigate the clinical and electrophysiological features of chronic inflammatory demyelinating polyneuropathy (CIDP) . Methods The clinical symptoms and signs of 11 patients with CIDP were studied, motor conduction velocity( MCV), sensory con-duction velocity (SCV) and Electromyography (EMG) were also respectively carried out on 54 motor nerves, 28 sensory nerves and 21 musclesof these 11 cases. The amplitudes of compound muscle action potential(CAMP) obtained from distal and proximal ends were compared to as-certain the presence of conduction block (CB) by stimulating the segments starting from the distal ends. Results More than 3 nerves werefound involved in 10 out of 11 cases, slow MCV were found in 52%, prolongation of the distal latency in 64%, reduction of the amplitudes ofCAMP in 68%, CB in 26%, slow SCV in 85. 7%. EMG revealed neurogenic damage in 81%. Conclusion CIDP is a peripheral de- myelinating neuropathy involving not only the prox imal and distal segments but also the sensory and motor nerves. If there were no conditionsto perform nerve biopsy, testing of protein in CSF and electrophysiology mightbe of important diagnostic value for CIDP.

    AIM: To investigate the effect of chronic inflammatory bowel disease (CIBD) specific risk factors for cholecystolithiasis,as duration and involvement pattern of the disease and prior surgery in patients with Crohn's disease (CD) and ulcerative colitis (UC).METHODS: A total of 222 patients with CD (135 females,87 males; average age, 35.8±11.8 years; range 17-81 years)and 88 patients with UC (39 females, 49 males; average age, 37.2±13.6 years; range 16-81 years) underwent clinical and ultrasound examinations. Besides age, sex and degree of obesity, patients' CIBD specific parameters, including duration and extent of disease and prior operations were documented and evaluated statistically using logistic regression.RESULTS: The overall prevalence of gallbladder stone disease in patients with CD was 13% (n = 30). Only age could be shown to be an independent risk factor (P = 0.014).Compared to a collective representative for the general population in the same geographic region, the prevalence of cholecystolithiasis was higher in all corresponding age groups. Patients with UC showed an overall prevalence of gallbladder stone disease of only 4.6%.CONCLUSION:Only age but not disease-specific factors such as duration and extent of disease, and prior surgery are independent risk factors for the development of cholecystolithiasis in patients with CIBD.

    Over the last four decades, immunohistochemistry (IHC) has become an invaluable technique to detect antigens in tissue sections. Compared to Western blotting analysis, IHC is advantageous in determining histological distribution and localization of the antigen. Another advantage, if one can access human formalin-fixed paraffin-embedded (FFPE) blocks of disease tissues, is that IHC makes it possible to analyze diseases retrospectively from archived pathological tissue specimens. In this chapter, we describe protocols used for both conventional and multiple immunostainings using FFPE tissue sections, which have been used for quantitative analysis of high endothelial venule (HEV)-like vessels and lymphocyte subsets attached to HEV-like vessels in our studies of chronic inflammatory gastrointestinal diseases. We also describe in detail a protocol using an L-selectinIgM chimera in situ binding assay on FFPE tissue sections for functional detection of L-selectin ligand carbohydrates expressed on HEV-like vessels. After presenting each protocol, we provide practical examples for its use obtained from our studies.

    Full Text Available Shift work and trans-time zone travel lead to insufficient sleep and numerous pathologies. Here, we examined sleep/wake dynamics during chronic exposure to environmental circadian disruption (ECD, and if chronic partial sleep loss associated with ECD influences the induction of shift-related inflammatory disorder. Sleep and wakefulness were telemetrically recorded across three months of ECD, in which the dark-phase of a light-dark cycle was advanced weekly by 6 h. A three month regimen of ECD caused a temporary reorganization of sleep (NREM and REM and wake processes across each week, resulting in an approximately 10% net loss of sleep each week relative to baseline levels. A separate group of mice were subjected to ECD or a regimen of imposed wakefulness (IW aimed to mimic sleep amounts under ECD for one month. Fos-immunoreactivity (IR was quantified in sleep-wake regulatory areas: the nucleus accumbens (NAc, basal forebrain (BF, and medial preoptic area (MnPO. To assess the inflammatory response, trunk blood was treated with lipopolysaccharide (LPS and subsequent release of IL-6 was measured. Fos-IR was greatest in the NAc, BF, and MnPO of mice subjected to IW. The inflammatory response to LPS was elevated in mice subjected to ECD, but not mice subjected to IW. Thus, the net sleep loss that occurs under ECD is not associated with a pathological immune response.

    Full Text Available The marine environment represents a relatively available source of functional ingredients that can be applied to various aspects of food processing, storage, and fortification. Moreover, numerous marine invertebrates based compounds have biological activities and also interfere with the pathogenesis of diseases. Isolated compounds from marine invertebrates have been shown to pharmacological activities and are helpful for the invention and discovery of bioactive compounds, primarily for deadly diseases like cancer, acquired immunodeficiency syndrome (AIDS, osteoporosis, and so forth. Extensive research within the last decade has revealed that most chronic illnesses such as cancer, neurological diseases, diabetes, and autoimmune diseases exhibit dysregulation of multiple cell signaling pathways that have been linked to inflammation. On the basis of their bioactive properties, this review focuses on the potential use of marine invertebrate derived compounds on anti-inflammatory and some chronic diseases such as cardiovascular disease, osteoporosis, diabetes, HIV, and cancer.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an immune-mediated disorder with variable symptoms and severity that can be difficult to diagnose. Intravenous immunoglobulin, plasma exchange and corticosteroids have all been proven to be beneficial in randomized controlled trials, although the proof for corticosteroids is less clear. Although these treatments are likely to be similar in efficacy, they differ in terms of their cost, availability and adverse effects. These characteristics should be taken into account when deciding which treatment to offer a patient. If there is no response to the first treatment option, one of the other treatments should be tried. Patients with a pure motor CIDP may deteriorate after corticosteroid treatment. Some patients do not respond or become refractory or intolerant to these conventional treatments. Those who become unresponsive to therapy should be checked again for the appearance of a monoclonal protein or other signs of malignancy. Over the years, small non-randomized studies have reported possible beneficial effects of various immunosuppressive agents. A Cochrane review concluded that currently there is insufficient evidence to decide whether these immunosuppressive drugs are beneficial in CIDP. When giving immunosuppressive drugs, one should be aware that some might even cause demyelinating disease. It is difficult to prove beneficial effects of these newer treatments since they have only been used in small groups of patients, who are refractory to other treatments, and often in combination with other treatments. CIDP patients can deteriorate during or after infections or improve spontaneously, making it more difficult to judge treatment efficacy. Various treatments for CIDP are described such as azathioprine, ciclosporin, cyclophosphamide, interferons, methotrexate, mycophenolate mofetil, rituximab and etanercept. An overview of these newer treatments, their mode of action, adverse effects and

    Limits of treatment in chronic inflammatory demyelinating poly(radiculo)neuropathies (CIDP) patients are better known thanks to recent Cochrane reviews. (1) Randomized controlled trials have only focused on short-term effects, but most patients need long-term therapy, (2) There are three proven effective treatments available (prednisone; intravenous immunoglobulin or IVIg and plasma exchange or PE) which are useful in more than 60 p. 100 of patients, (3) New open studies indicated possible efficacy for mycophenolate, rituximab, etanercept, ciclosporine and interferons, and (4) Whether CIDP variants need specific treatment is still unknown. Many CIDP patients need treatment for years. The fear of side effects during long-term steroid treatment, the high costs of IVIg, the necessity for specialized equipment and the invasive nature of PE, are important factors determining the choice for one of these treatments. In most up-to-date treatment options, patients are initially treated with IVIg at a dosage of 2 g/kg administered for 25 days, clinical improvement can be judged within 10 days. The percentage of patients responding seems to be approximately 70 percent, with a very high chance (approximately 85 percent) that repeated administration of IVIg will be necessary, explaining why most neurologists add an immunosuppressive drug at this stage, but there is no consensus concerning the best drug to be used. Combinations of drugs are most likely to be useful in the next future, using IVIg, prednisone, and a immunosuppressor agent, such as mycophenolate, rituximab, etanercept, or ciclosporine. General measures to rehabilitate patients and to manage symptoms like fatigue and other residual findings are important.

    Directory of Open Access Journals (Sweden)

    Bosma-den Boer Margarethe M

    2012-04-01

    Full Text Available Abstract Serhan and colleagues introduced the term "Resoleomics" in 1996 as the process of inflammation resolution. The major discovery of Serhan's work is that onset to conclusion of an inflammation is a controlled process of the immune system (IS and not simply the consequence of an extinguished or "exhausted" immune reaction. Resoleomics can be considered as the evolutionary mechanism of restoring homeostatic balances after injury, inflammation and infection. Under normal circumstances, Resoleomics should be able to conclude inflammatory responses. Considering the modern pandemic increase of chronic medical and psychiatric illnesses involving chronic inflammation, it has become apparent that Resoleomics is not fulfilling its potential resolving capacity. We suggest that recent drastic changes in lifestyle, including diet and psycho-emotional stress, are responsible for inflammation and for disturbances in Resoleomics. In addition, current interventions, like chronic use of anti-inflammatory medication, suppress Resoleomics. These new lifestyle factors, including the use of medication, should be considered health hazards, as they are capable of long-term or chronic activation of the central stress axes. The IS is designed to produce solutions for fast, intensive hazards, not to cope with long-term, chronic stimulation. The never-ending stress factors of recent lifestyle changes have pushed the IS and the central stress system into a constant state of activity, leading to chronically unresolved inflammation and increased vulnerability for chronic disease. Our hypothesis is that modern diet, increased psycho-emotional stress and chronic use of anti-inflammatory medication disrupt the natural process of inflammation resolution ie Resoleomics.

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

    Background Bronchial asthma (BA) and chronic obstructive pulmonary disease (COPD) are both inflammatory airway diseases with different characteristics. However, there are many patients who suffer from both BA and COPD. This study was to evaluate changes of inflammatory airway features and hypothalamic-pituitary-adrenal (HPA) axis function in asthmatic rats combined with COPD.Methods Brown Norway (BN) rats were used to model the inflammatory airway diseases of BA, COPD and COPD+BA.These three models were compared and evaluated with respect to clinical symptoms, pulmonary histopathology, airway hyperresponsiveness (AHR), inflammatory cytokines and HPA axis function.Results The inflammatory airway features and HPA axis function in rats in the COPD+BA model group were greatly influenced. Rats in this model group showed features of the inflammatory diseases BA and COPD. The expression of inflammatory cytokines in this model group might be up or downregulated when both disease processes are present. The levels of corticotrophin releasing hormone mRNA and corticosterone in this model group were both significantly decreased than those in the control group (P <0.05).Conclusions BN rat can be used as an animal model of COPD+BA. By evaluating this animal model we found that the features of inflammation in rats in this model group seem to be exaggerated. The HPA axis functions in rats in this model group have been disturbed or impaired, which is prominent at the hypothalamic level.

  6. PPARγ as a Potential Target to Treat Airway Mucus Hypersecretion in Chronic Airway Inflammatory Diseases

    Directory of Open Access Journals (Sweden)

    Yongchun Shen

    2012-01-01

    Full Text Available Airway mucus hypersecretion (AMH is a key pathophysiological feature of chronic airway inflammatory diseases such as bronchial asthma, cystic fibrosis, and chronic obstructive pulmonary disease. AMH contributes to the pathogenesis of chronic airway inflammatory diseases, and it is associated with reduced lung function and high rates of hospitalization and mortality. It has been suggested that AMH should be a target in the treatment of chronic airway inflammatory diseases. Recent evidence suggests that a key regulator of airway inflammation, hyperresponsiveness, and remodeling is peroxisome proliferator-activated receptor gamma (PPARγ, a ligand-activated transcription factor that regulates adipocyte differentiation and lipid metabolism. PPARγ is expressed in structural, immune, and inflammatory cells in the lung. PPARγ is involved in mucin production, and PPARγ agonists can inhibit mucin synthesis both in vitro and in vivo. These findings suggest that PPARγ is a novel target in the treatment of AMH and that further work on this transcription factor may lead to new therapies for chronic airway inflammatory diseases.

    Recent experimental findings have shown the ability of mesenchymal stromal cells (MSCs) to home to damaged tissues and to produce paracrine factors with anti-inflammatory properties, potentially resulting in reduction of inflammation and functional recovery of the damaged tissues. Prompted by these intriguing properties and on the basis of encouraging preclinical data, MSCs are currently being studied in several immune-mediated disorders. Inflammatory bowel diseases (IBD) represent a setting in which MSCs-based therapy has been extensively investigated. Phase I and II studies have documented the safety and feasibility of MSCs. However, efficacy results have so far been conflicting. In this review, we will discuss the biologic rationale that makes MSCs a promising therapeutic tool for IBD, and analyze recent experimental and clinical findings, highlighting current limitations and future perspectives of MSCs-related immunotherapy for IBD.

    Asthma and chronic obstructive pulmonary disease (COPD) are chronic inflammatory diseases of the airway, although the drivers and site of the inflammation differ between diseases. Asthmatics with a neutrophilic airway inflammation are associated with a poor response to corticosteroids, whereas asthmatics with eosinophilic inflammation respond better to corticosteroids. Biologicals targeting the Th2-eosinophil nexus such as anti–interleukin (IL)-4, anti–IL-5, and anti–IL-13 are ineffective in ...

    Mast cells were described by Erhlich at the end of XIX-th century. Their role was deeply investigated in asthma and allergy. The massive degranulation of mast cells in allergy can lead to anaphylactic shock. Recently, mast cells have been recognized again as a very interesting topic for investigation, due to their possible role in chronic inflammation. Moreover, through adenosine receptors, mast cells can be activated or inactivated. That is why these cells are regarded as a potential target of new drugs. It has been reported, that mast cells generate intracellular reactive oxygen species (ROS) in response to stimulation with divergent physiologically relevant stimulants. The intensification of ROS production may be measured by the level of carbonyl groups, as a marker of protein peroxidation. However, the role of mast cells in other than asthma diseases with chronic inflammation needs further investigation. It was found out that the information about mast cell distribution in colonic mucosa may serve as help in differentiation between inflammatory bowel disease and collagenous colitis. Moreover, its accumulation in focal active gastritis was confirmed in patients with Crohn's disease. An important role in regulation of inflammatory process seems to be reserved for adenosine receptors present on mastocytes. The activation of mast cells through the adenosine receptor is connected with 11-8 release, which stimulate the migration of leukocytes and oxidation reactions. The detection of mast cells in tissues should not be limited only to the simple histologic examination. It should be completed by the detection of products of degranulation, e.g. tryptase. This is the way to find out their actual function and state of activation. PMID:17203808

  15. The Case for Increased Physical Activity in Chronic Inflammatory Bowel Disease: A Brief Review.

    2016-06-01

    Regular physical activity reduces the risk of colon cancer, but there is little information on the merits of such activity in the prevention and management of chronic inflammatory bowel disease (CIBD). The present systematic review thus documents current levels of habitual physical activity and aerobic and muscular function in CIBD, and examines the safety, practicality and efficacy of exercise programmes in countering the disease process, correcting functional deficits and enhancing quality of life. A systematic search of the Ovid/Medline database from January 1996 to May 2015 linked the terms physical activity/motor activity/physical fitness/physical training/physical education/training/exercise/exercise therapy with Crohn's disease/colitis/ulcerative colitis/inflammatory bowel disease, supplementing this information by a scanning of reference lists and personal files.12 of 16 published studies show a low level of habitual physical activity in CIBD, with sub-normal values for aerobic power, lean tissue mass and muscular strength. 3 of 4 studies suggest physical activity may reduce the risk of developing IBD, and 11 interventions all note that exercise programmes are well tolerated with some decreases of disease activity, and functional gains leading to an increased health-related quality of life. Moreover, programme compliance rates compare favourably with those seen in the treatment of other chronic conditions. More information on mechanisms is needed, but regular moderate aerobic and/or resistance exercise improves the health status of patients with CIBD both by modulating immune function and by improving physical function. A regular exercise programme should thus become an important component in the management of CIBD. PMID:27116344

    Chronic venous ulcer (CVU) represents a dreaded complication of chronic venous disease (CVD). The onset of infection may further delay the already precarious healing process in such lesions. Some evidences have shown that matrix metalloproteinases (MMPs) are involved and play a central role in both CVUs and infectious diseases. Two groups of patients were enrolled to evaluate the expression of MMPs in infected ulcers and the levels of inflammatory cytokines as well as their prevalence. Group I comprised 63 patients (36 females and 27 males with a median age of 68·7 years) with infected CVUs, and group II (control group) comprised 66 patients (38 females and 28 males with a median age of 61·2 years) with non-infected venous ulcers. MMP evaluation and dosage of inflammatory cytokines in plasma and wound fluid was performed by means of enzyme-linked immunosorbent assay test; protein extraction and immunoblot analysis were performed on biopsied wounds. The first three most common agents involved in CVUs were Staphylococcus aureus (38·09%), Corynebacterium striatum (19·05%) and Pseudomonas aeruginosa (12·7%). In this study, we documented overall higher levels of MMP-1 and MMP-8 in patients with infected ulcers compared to those with uninfected ulcers that showed higher levels of MMP-2 and MMP-9. We also documented higher levels of interleukin (IL)-1, IL-6, IL-8, vascular endothelial growth factor and tumour necrosis factor-alpha in patients with infected ulcers with respect to those with uninfected ulcers, documenting a possible association between infection, MMP activation, cytokine secretions and symptoms. The present results could represent the basis for further studies on drug use that mimic the action of tissue inhibitors of metalloproteinases in order to make infected CVU more manageable.

  17. Blood Dendritic Cells: Canary in the Coal Mine to Predict Chronic Inflammatory Disease?

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available The majority of risk factors for chronic inflammatory diseases are unknown. This makes personalized medicine for assessment, prognosis, and choice of therapy very difficult. It is becoming increasingly clear, however, that low-grade subclinical infections may be an underlying cause of many chronic inflammatory diseases and thus may contribute to secondary outcomes (e.g. cancer. Many diseases are now categorized as inflammatory-mediated diseases that stem from a dysregulation in host immunity. There is a growing need to study the links between low-grade infections, the immune responses they elicit, and how this impacts overall health. One such link explored in detail here is the extreme sensitivity of myeloid dendritic cells (mDC in peripheral blood to chronic low-grade infections and the role that these mDCs play in arbitrating the resulting immune responses. We find that emerging evidence supports a role for pathogen-induced mDCs in chronic inflammation leading to increased risk of secondary clinical disease. The mDCs that are elevated in the blood as a result of low-grade bacteremia often do not trigger a productive immune response, but can disseminate the pathogen throughout the host. This aberrant trafficking of mDCs can accelerate systemic inflammatory disease progression. Conversely, restoration of DC homeostasis may aid in pathogen elimination and minimize dissemination. Thus it would seem prudent when assessing chronic inflammatory disease risk to consider blood mDC numbers, and the microbial content (microbiome and activation state of these mDCs. These may provide important clues (the canary in the coal mine of high inflammatory disease risk. This will facilitate development of novel immunotherapies to eliminate such smoldering infections in atherosclerosis, cancer, rheumatoid arthritis, and pre-eclampsia.

  4. Early severe inflammatory responses to uropathogenic E. coli predispose to chronic and recurrent urinary tract infection.

    Directory of Open Access Journals (Sweden)

    Thomas J Hannan

    Full Text Available Chronic infections are an increasing problem due to the aging population and the increase in antibiotic resistant organisms. Therefore, understanding the host-pathogen interactions that result in chronic infection is of great importance. Here, we investigate the molecular basis of chronic bacterial cystitis. We establish that introduction of uropathogenic E. coli (UPEC into the bladders of C3H mice results in two distinct disease outcomes: resolution of acute infection or development of chronic cystitis lasting months. The incidence of chronic cystitis is both host strain and infectious dose-dependent. Further, development of chronic cystitis is preceded by biomarkers of local and systemic acute inflammation at 24 hours post-infection, including severe pyuria and bladder inflammation with mucosal injury, and a distinct serum cytokine signature consisting of elevated IL-5, IL-6, G-CSF, and the IL-8 analog KC. Mice deficient in TLR4 signaling or lymphocytes lack these innate responses and are resistant, to varying degrees, to developing chronic cystitis. Treatment of C3H mice with the glucocorticoid anti-inflammatory drug dexamethasone prior to UPEC infection also suppresses the development of chronic cystitis. Finally, individuals with a history of chronic cystitis, lasting at least 14 days, are significantly more susceptible to redeveloping severe, chronic cystitis upon bacterial challenge. Thus, we have discovered that the development of chronic cystitis in C3H mice by UPEC is facilitated by severe acute inflammatory responses early in infection, which subsequently are predisposing to recurrent cystitis, an insidious problem in women. Overall, these results have significant implications for our understanding of how early host-pathogen interactions at the mucosal surface determines the fate of disease.

    Chronic idiopathic demyelinating polyradiculoneuropathy (CIDP) is a rare disease, the most frequent one within the spectrum of the so-called "chronic immune-mediated neuropathies". Challenges in the treatment of CIDP firstly concern its diagnosis, which may be difficult, mainly for the atypical forms. Secondly, challenges encompass the choice of the first-line treatment, such as corticosteroids, intravenous immunoglobulins (IVIg), and plasma exchanges (PE) that have been proven as efficacious by several randomized controlled trials (RCT). Recent reports have focused on both different regimens of corticosteroids, and the occurrence of relapses following treatment with either corticosteroids or IVIg. These data may be helpful for the choice of the first-line treatment and may result in changing the guidelines for treatment of CIDP in clinical practice. The third and more difficult challenge is to manage long-term treatment for CIDP, since no immunomodulatory treatment has to date been proven as efficacious in this situation. Lastly, challenges in the treatment concern the choice of the best outcome measure for CIDP in RCT and clinical practice. The aim of this article is to overview the results of the more recently reported published trials for CIDP, and to give some insights for the current and future management of CIDP.

    Liver X receptor (LXR), a nuclear hormone receptor, is an essential regulator of immune responses. Activation of LXR-mediated transcription by synthetic agonists, such as T0901317 and GW3965, attenuates progression of inflammatory disease in animal models. However, the adverse effects of these conventional LXR agonists in elevating liver lipids have impeded exploitation of this intriguing mechanism for chronic therapy. Here, we explore the ability of a series of sterol-based LXR agonists to alleviate inflammatory conditions in mice without hepatotoxicity. We show that oral treatment with sterol-based LXR agonists in mice significantly reduces dextran sulfate sodium colitis-induced body weight loss, which is accompanied by reduced expression of inflammatory markers in the large intestine. The anti-inflammatory property of these agonists is recapitulated in vitro in mouse lamina propria mononuclear cells, human colonic epithelial cells, and human peripheral blood mononuclear cells. In addition, treatment with LXR agonists dramatically suppresses inflammatory cytokine expression in a model of traumatic brain injury. Importantly, in both disease models, the sterol-based agonists do not affect the liver, and the conventional agonist T0901317 results in significant liver lipid accumulation and injury. Overall, these results provide evidence for the development of sterol-based LXR agonists as novel therapeutics for chronic inflammatory diseases.-Yu, S., Li, S., Henke, A., Muse, E.

  7. The Central Role of the Gut Microbiota in Chronic Inflammatory Diseases

    Directory of Open Access Journals (Sweden)

    Caroline Marcantonio Ferreira

    2014-01-01

    Full Text Available The commensal microbiota is in constant interaction with the immune system, teaching immune cells to respond to antigens. Studies in mice have demonstrated that manipulation of the intestinal microbiota alters host immune cell homeostasis. Additionally, metagenomic-sequencing analysis has revealed alterations in intestinal microbiota in patients suffering from inflammatory bowel disease, asthma, and obesity. Perturbations in the microbiota composition result in a deficient immune response and impaired tolerance to commensal microorganisms. Due to altered microbiota composition which is associated to some inflammatory diseases, several strategies, such as the administration of probiotics, diet, and antibiotic usage, have been utilized to prevent or ameliorate chronic inflammatory diseases. The purpose of this review is to present and discuss recent evidence showing that the gut microbiota controls immune system function and onset, development, and resolution of some common inflammatory diseases.

    In the inflammatory bowel diseases (IBD) that affect dogs and cats there appears to be dysregulation of normal mucosal immunity, characterised by polyclonal lymphocytic infiltrates which are presumably specific for luminal antigens. There is an absence of a classical polarisation of either T-helper (Th) 1 or Th2 cytokine responses, although increased expression of mRNA for interleukin (IL) 2 and IL-12p40 and a shift towards mucosal immunoglobulin (Ig) G production are consistent findings, whilst variable responses are seen in tumour necrosis factor-alpha (TNF-alpha), IL-1, IL-4, IL-6, and interferon-gamma (IFN-gamma). Increased mucosal permeability and deranged intestinal motility are common sequelae. Despite obvious similarities with Crohn's disease and ulcerative colitis in humans, important differences exist. Of these, the diffuse superficial nature but with no Th1 or Th2 bias, and the prevalence of proximal small intestinal disease are notable. Potential hypotheses for these disparities include specific differences in the types or locations of agonistic gut flora, diffuse abnormalities in microbial-host interactions, a greater importance of diet, or anatomical or cellular differences in mucosal immune responses. Although specific pathogens and genetic susceptibilities may be involved, quantitative or qualitative changes in the normal flora or abnormal responses to a normal flora are more likely to be involved in the immunopathogenesis. Dietary influences include a large source of antigen, promotion of abnormal microbial growth through Maillard compounds within canned diets, and specific macro- and micronutrient deficiencies. Although dependent on a histopathological diagnosis, limitations of biopsies procured endoscopically, lack of histopathological standardisation and difficulty distinguishing inflammation from neoplasia remain significant problems.

    Jan Möhrke

    Full Text Available Recent studies on Multiple Sclerosis (MS pathology mention the involvement of "tertiary B cell follicles" in MS pathogenesis. This inflammatory process, which occurs with interindividually great variance, might be a link between MS pathology and headaches. The aim of this study was to detect the prevalence of headaches and of subtypes of headaches (migraine, cluster, tension-type headache [TTH] in an unselected MS collective and to compile possibly influencing factors. Unselected MS patients (n = 180 with and without headache were examined by a semi-structured interview using a questionnaire about headache, depression and the health status. Additionally clinical MS data (expanded disability state score [EDSS], MS course, medication, disease duration were gathered. N = 98 MS patients (55.4% reported headaches in the previous 4 weeks. We subsequently grouped headache patients according to the IHS criteria and detected 16 (16.3% MS patients suffering from migraine (migraine with aura: 2 [2%]; migraine without aura: 14 [14.3%], 23 (23.5% suffering from TTH and none with a cluster headache. Thus, headaches of 59 (60.2% MS patients remained unclassified. When comparing MS patients with and without headaches significant differences in age, gender, MS course, physical functioning, pain and social functioning occurred. MS patients with headaches were significantly younger of age (p = 0.001, female (p = 0.001 and reported more often of a clinically isolated syndrome (CIS and relapsing/remitting MS (RRMS instead of secondary chronic progressive MS (SCP. EDSS was significantly lower in MS patients suffering from headaches compared to the MS patients without headaches (p = 0.001. In conclusion headache in MS patients is a relevant symptom, especially in early stages of the MS disease. Especially unclassified headache seems to represent an important symptom in MS course and requires increased attention.

    These studies were performed to test the benefit of resistant starch on ulcerative colitis via prebiotic and butyrate effects. Butyrate, propionate, and acetate are produced in the colon of mammals as a result of microbial fermentation of resistant starch and other dietary fibers. Butyrate plays an important role in the colonic mucosal growth and epithelial proliferation. A reduction in the colonic butyrate level induces chronic mucosal atrophy. Short-chain fatty acid enemas increase mucosal generation, crypt length, and DNA content of the colonocytes. They also ameliorate symptoms of ulcerative colitis in human patients and rats injected with trinitrobenzene sulfonic acid (TNBS). Butyrate, and also to a lesser degree propionate, are substrates for the aerobic energy metabolism, and trophic factors of the colonocytes. Adverse butyrate effects occur in normal and neoplastic colonic cells. In normal cells, butyrate induces proliferation at the crypt base, while inhibiting proliferation at the crypt surface. In neoplastic cells, butyrate inhibits DNA synthesis and arrests cell growth in the G1 phase of the cell cycle. The improvement of the TNBS-induced colonic inflammation occurred earlier in the resistant starch (RS)-fed rats than in the RS-free group. This benefit coincided with activation of colonic epithelial cell proliferation and the subsequent restoration of apoptosis. The noncollagenous basement membrane protein laminin was regenerated initially in the RS-fed group, demonstrating what could be a considered lower damage to the intestinal barrier function. The calculation of intestinal short-chain fatty acid absorption confirmed this conclusion. The uptake of short-chain fatty acids in the colon is strongly inhibited in the RS-free group, but only slightly reduced in the animals fed with RS. Additionally, RS enhanced the growth of intestinal bacteria assumed to promote health. Further studies involving patients suffering from ulcerative colitis are necessary to

    Full Text Available Abstract Background Interleukin 1 beta (IL-1β plays an important role in a number of chronic and acute inflammatory diseases. To understand the role of IL-1β in disease processes and develop an in vivo screening system for anti-inflammatory drugs, a transgenic mouse line was generated which incorporated the transgene firefly luciferase gene driven by a 4.5-kb fragment of the human IL-1β gene promoter. Luciferase gene expression was monitored in live mice under anesthesia using bioluminescence imaging in a number of inflammatory disease models. Results In a LPS-induced sepsis model, dramatic increase in luciferase activity was observed in the mice. This transgene induction was time dependent and correlated with an increase of endogenous IL-1β mRNA and pro-IL-1β protein levels in the mice. In a zymosan-induced arthritis model and an oxazolone-induced skin hypersensitivity reaction model, luciferase expression was locally induced in the zymosan injected knee joint and in the ear with oxazolone application, respectively. Dexamethasone suppressed the expression of luciferase gene both in the acute sepsis model and in the acute arthritis model. Conclusion Our data suggest that the transgenic mice model could be used to study transcriptional regulation of the IL-1β gene expression in the inflammatory process and evaluation the effect of anti-inflammatory drug in vivo.

    2012-01-01

    Aspirin and non-steroidal anti-inflammatory drugs (NSAIDS) may prevent sporadic colonic neoplasia and reduce the polyp burden in familial adenomatous polyposis. A 41-year-old pharmacologist with no family history of intestinal polyps or cancer chronically consumed daily aspirin and other non-steroidal anti-inflammatory drugs for decades despite recurrent and multiple gastric ulcers. A cancerous polyp in the colon was endoscopically resected. Over the next 2 decades, almost 50 adenomatous polyps were removed from the rest of his colon and duodenum, typical of an attenuated form of adenomatous polyposis. Chronic and habitual use of aspirin or NSAIDS may have important significance in delaying the appearance of adenomas. The observations here emphasize the important implications for clinical risk assessment in screening programs designed to detect or prevent colon cancer.

    2016-05-01

    Anemia coexists with inflammatory bowel disease (IBD) in up to two-thirds of patients, significantly impairing quality of life. The most common types of anemia in patients with IBD are iron deficiency anemia and anemia of chronic disease, which often overlap. In most cases, available laboratory tests allow successful diagnosis of iron deficiency, where difficulties appear, recently established indices such as soluble transferrin-ferritin ratio or percentage of hypochromic red cells are used. In this review, we discuss the management of the most common types of anemia in respect of the latest available data. Thus, we provide the mechanisms underlying pathophysiology of these entities; furthermore, we discuss the role of hepcidin in developing anemia in IBD. Next, we present the treatment options for each type of anemia and highlight the importance of individual choice of action. We also focus on newly developed intravenous iron preparations and novel, promising drug candidates targeting hepcidin. Concurrently, we talk about difficulties in differentiating between the true and functional iron deficiency, and discuss tools facilitating the process. Finally, we emphasize the importance of proper diagnosis and treatment of anemia in IBD. We conclude that management of anemia in patients with IBD is tricky, and appropriate screening of patients regarding anemia is substantial. PMID:26818422

    Asthma and chronic obstructive pulmonary disease (COPD) are chronic inflammatory diseases of the airway, although the drivers and site of the inflammation differ between diseases. Asthmatics with a neutrophilic airway inflammation are associated with a poor response to corticosteroids, whereas asthmatics with eosinophilic inflammation respond better to corticosteroids. Biologicals targeting the Th2-eosinophil nexus such as anti-interleukin (IL)-4, anti-IL-5, and anti-IL-13 are ineffective in asthma as a whole but are more effective if patients are selected using cellular (eg, eosinophils) or molecular (eg, periostin) biomarkers. This highlights the key role of individual inflammatory mediators in driving the inflammatory response and for accurate disease phenotyping to allow greater understanding of disease and development of patient-oriented antiasthma therapies. In contrast to asthmatic patients, corticosteroids are relatively ineffective in COPD patients. Despite stratification of COPD patients, the results of targeted therapy have proved disappointing with the exception of recent studies using CXC chemokine receptor (CXCR)2 antagonists. Currently, several other novel mediator-targeted drugs are undergoing clinical trials. As with asthma specifically targeted treatments may be of most benefit in specific COPD patient endotypes. The use of novel inflammatory mediator-targeted therapeutic agents in selected patients with asthma or COPD and the detection of markers of responsiveness or nonresponsiveness will allow a link between clinical phenotypes and pathophysiological mechanisms to be delineated reaching the goal of endotyping patients.

    Full Text Available A vast variety of nonstructural proteins have been studied for their key roles and involvement in a number of biological phenomenona. Interleukin-32 is a novel cytokine whose presence has been confirmed in most of the mammals except rodents. The IL-32 gene was identified on human chromosome 16 p13.3. The gene has eight exons and nine splice variants, namely, IL-32α, IL-32β, IL-32γ, IL-32δ, IL-32ε, IL-32ζ, IL-32η, IL-32θ, and IL-32s. It was found to induce the expression of various inflammatory cytokines including TNF-α, IL-6, and IL-1β as well as macrophage inflammatory protein-2 (MIP-2 and has been reported previously to be involved in the pathogenesis and progression of a number of inflammatory disorders, namely, inflammatory bowel disease (IBD, gastric inflammation and cancer, rheumatoid arthritis, and chronic obstructive pulmonary disease (COPD. In the current review, we have highlighted the involvement of IL-32 in gastric cancer, gastric inflammation, and chronic rhinosinusitis. We have also tried to explore various mechanisms suspected to induce the expression of this extraordinary cytokine as well as various mechanisms of action employed by IL-32 during the mediation and progression of the above said problems.

    AIM: To investigate the impact of chronic fatigue on disease-related worries in inflammatory bowel disease (IBD) and the potential multicolinearity between subjective questionnaires. METHODS: Patients in remission or with mild-tomoderate disease activity completed the fatigue questionnaire (FQ), the rating form of IBD patient concerns (RFIPC), the Short-Form 36 (SF-36), and IBD questionnaire (N-IBDQ). In addition, clinical and epidemiological data were obtained. RESULTS: In total, 140 patients were included; of which 92 were diagnosed with ulcerative colitis and 48 with Crohn's disease. the mean age of patients with chronic fatigue was 44.2 years (SD =15.8) and for non-fatigued patients was 44.7 years (SD = 16.0). Chrnnic fatigued patients had clinically significantly increased levels of disease-related worries, as measured by Cohen's d effect size. Worries about having an ostomy bag, loss of bowel control, and energy levels were most prominent in both chronic fatigued and non-chronic fatigued IBD patients. Variance inflation factor (VIF) and tolerance indicated that there were no problematic multicolinearity among the FQ, RFIPC, SF-36 and N-IBDQ responses (VIF 2). CONCLUSION: Chronic fatigue is associated with increased levels of disease-related worries and concerns in IBD. Increased levels of worries were also associated with impaired health-related quality of life.

  16. Doxycycline Promotes Carcinogenesis & Metastasis via Chronic Inflammatory Pathway: An In Vivo Approach.

    Directory of Open Access Journals (Sweden)

    Neha Nanda

    Full Text Available Doxycycline (DOX exhibits anti-inflammatory, anti-tumor, and pro-apoptotic activity and is being tested in clinical trials as a chemotherapeutic agent for several cancers, including colon cancer.In the current study, the chemotherapeutic activity of doxycycline was tested in a rat model of colon carcinogenesis, induced by colon specific cancer promoter, 1,2, dimethylhydrazine (DMH as well as study the effect of DOX-alone on a separate group of rats.Doxycycline administration in DMH-treated rats (DMH-DOX unexpectedly increased tumor multiplicity, stimulated progression of colonic tumor growth from adenomas to carcinomas and revealed metastasis in small intestine as determined by macroscopic and histopathological analysis. DOX-alone treatment showed markedly enhanced chronic inflammation and reactive hyperplasia, which was dependent upon the dose of doxycycline administered. Moreover, immunohistochemical analysis revealed evidence of inflammation and anti-apoptotic action of DOX by deregulation of various biomarkers.These results suggest that doxycycline caused chronic inflammation in colon, small intestine injury, enhanced the efficacy of DMH in tumor progression and provided a mechanistic link between doxycycline-induced chronic inflammation and tumorigenesis. Ongoing studies thus may need to focus on the molecular mechanisms of doxycycline action, which lead to its inflammatory and tumorigenic effects.

  17. Acute Inflammatory Bowel Disease Complicating Chronic Alcoholism and Mimicking Carcinoid Syndrome

    Directory of Open Access Journals (Sweden)

    Piercarlo Ballo

    2012-08-01

    Full Text Available We report the case of a woman with a history of chronic alcohol abuse who was hospitalized with diarrhea, severe hypokalemia refractory to potassium infusion, nausea, vomiting, abdominal pain, alternations of high blood pressure with phases of hypotension, irritability and increased urinary 5-hydroxyindoleacetic acid and cortisol. Although carcinoid syndrome was hypothesized, abdominal computed tomography and colonoscopy showed non-specific inflammatory bowel disease with severe colic wall thickening, and multiple colic biopsies confirmed non-specific inflammation with no evidence of carcinoid cells. During the following days diarrhea slowly decreased and the patient’s condition progressively improved. One year after stopping alcohol consumption, the patient was asymptomatic and serum potassium was normal. Chronic alcohol exposure is known to have several deleterious effects on the intestinal mucosa and can favor and sustain local inflammation. Chronic alcohol intake may also be associated with high blood pressure, behavior disorders, abnormalities in blood pressure regulation with episodes of hypotension during hospitalization due to impaired baroreflex sensitivity in the context of an alcohol withdrawal syndrome, increased urinary 5-hydroxyindoleacetic acid as a result of malabsorption syndrome, and increased urinary cortisol as a result of hypothalamic-pituitary-adrenal axis dysregulation. These considerations, together with the regression of symptoms and normalization of potassium levels after stopping alcohol consumption, suggest the intriguing possibility of a alcohol-related acute inflammatory bowel disease mimicking carcinoid syndrome.

  18. Is There a Regulatory Role of Immunoglobulins on Tissue Forming Cells Relevant in Chronic Inflammatory Lung Diseases?

    Directory of Open Access Journals (Sweden)

    Michael Roth

    2011-01-01

    Full Text Available Epithelial cells, fibroblasts and smooth muscle cells together form and give structure to the airway wall. These three tissue forming cell types are structure giving elements and participate in the immune response to inhaled particles including allergens and dust. All three cell types actively contribute to the pathogenesis of chronic inflammatory lung diseases such as asthma and chronic obstructive pulmonary disease (COPD. Tissue forming cells respond directly to allergens through activated immunoglobulins which then bind to their corresponding cell surface receptors. It was only recently reported that allergens and particles traffic through epithelial cells without modification and bind to the immunoglobulin receptors on the surface of sub-epithelial mesenchymal cells. In consequence, these cells secrete pro-inflammatory cytokines, thereby extending the local inflammation. Furthermore, activation of the immunoglobulin receptors can induce proliferation and tissue remodeling of the tissue forming cells. New studies using anti-IgE antibody therapy indicate that the inhibition of immunoglobulins reduces the response of tissue forming cells. The unmeasured questions are: (i why do tissue forming cells express immunoglobulin receptors and (ii do tissue forming cells process immunoglobulin receptor bound particles? The focus of this review is to provide an overview of the expression and function of various immunoglobulin receptors.

    Marika eSarfati

    2015-08-01

    Full Text Available Basophils are, together with mast cells, typical innate effector cells of allergen-induced IgE-dependent allergic diseases. Both cell types express the high affinity receptor for IgE (FcεR1, release histamine, inflammatory mediators and cytokines following FcεR1 cross-linking. Basophils are rare granulocytes in blood, lymphoid and non-lymphoid tissues and the difficulties to detect and isolate these cells has hampered the study of their biology and the understanding of their possible role in pathology. Furthermore, the existence of other FcεR1-expressing cells, including professional Ag-presenting dendritic cells, generated some controversy regarding the ability of basophils to express MHC Class II molecules, present Ag and drive naïve T cell differentiation into Th2 cells. The focus of this review is to present the recent advances on the interactions between basophils and peripheral blood and tissue memory Th1, Th2 and Th17 cells, as well as their potential role in IgE-independent non allergic chronic inflammatory disorders, including human inflammatory bowel diseases. Basophils interactions with the innate players of IgE-dependent allergic inflammation, particularly innate lymphoid cells, will also be considered. The previously unrecognized function for basophils in skewing adaptive immune responses opens novel perspectives for the understanding of their contribution to the pathogenesis of inflammatory diseases.

    Lee, Kyung-Ah; Lee, Won-Jae

    2014-01-01

    The association between deregulated intestinal microbial consortia and host diseases has been recognized since the birth of microbiology over a century ago. Intestinal dysbiosis refers to a state where living metazoans harbor harmful intestinal microflora. However, there is still an issue of whether causality arises from the host or the microbe because it is unclear whether deregulation of the gut microbiota community is the consequence or cause of the host disease. Recent studies using Drosophila and its simple microbiota have provided a valuable model system for dissecting the molecular mechanisms of intestinal dysbiosis. In this review, we examine recent exciting observations in Drosophila gut-microbiota interactions, particularly the links among the host immune genotype, the microbial community structure, and the host inflammatory phenotype. Future genetic analyses using Drosophila model system will provide a valuable outcome for understanding the evolutionarily conserved mechanisms that underlie intestinal dysbiosis and chronic inflammatory diseases.

    Stübgen, Joerg-Patrick

    2013-03-15

    Chronic inflammatory demyelinating polyneuropathy (CIDP) is a group of idiopathic, acquired, immune-mediated inflammatory demyelinating diseases of the peripheral nervous system. A majority of patients with CIDP respond to "first-line" treatment with IVIG, plasmapheresis and/or corticosteroids. There exists insufficient evidence to ascertain the benefit of treatment with "conventional" immunosuppressive drugs. The inconsistent efficacy, long-term financial burden and health risks of non-specific immune altering therapy have drawn recurrent attention to the possible usefulness of a variety of biological agents that target key aspects in the CIDP immunopathogenic pathways. This review aims to give an updated account of the scientific rationale and potential use of biological therapeutics in patients with CIDP. No specific treatment recommendations are given. The discovery, development and application of biological markers by modern molecular diagnostic techniques may help identify drug-naïve or treatment-resistant CIDP patients most likely to respond to targeted immunotherapy.

    Oral cancer kills about 1 person every hour each day in the United States and is the sixth most prevalent cancer worldwide. The pro-inflammatory cytokine 'macrophage migration inhibitory factor' (MIF) has been shown to be expressed in oral cancer patients, yet its precise role in oral carcinogenesis is not clear. In this study, we examined the impact of global Mif deletion on the cellular and molecular process occurring during oral carcinogenesis using a well-established mouse model of oral cancer with the carcinogen 4-nitroquinoline-1-oxide (4NQO). C57BL/6 Wild-type (WT) and Mif knock-out mice were administered with 4NQO in drinking water for 16 weeks, then regular drinking water for 8 weeks. Mif knock-out mice displayed fewer oral tumor incidence and multiplicity, accompanied by a significant reduction in the expression of pro-inflammatory cytokines Il-1β, Tnf-α, chemokines Cxcl1, Cxcl6 and Ccl3 and other molecular biomarkers of oral carcinogenesis Mmp1 and Ptgs2. Further, systemic accumulation of myeloid-derived tumor promoting immune cells was inhibited in Mif knock-out mice. Our results demonstrate that genetic Mif deletion reduces the incidence and severity of oral carcinogenesis, by inhibiting the expression of chronic pro-inflammatory immune mediators. Thus, targeting MIF is a promising strategy for the prevention or therapy of oral cancer. PMID:27164411

The prevalence of Wegener’s granulomatosis is three cases per 100,000 patients. Cardiovascular, neurologic, cutaneous, and joint manifestations have been reported in many case reports and case series. Gastrointestinal manifestations are less noted in Wegener’s granulomatosis, although they have been previously reported in the form of intestinal perforation and intestinal ischemia. Additionally, there are characteristic findings of vasculitis that are noted with active Wegener’s granulomatosis of the small bowel. We report a case of an elderly patient who presented with weight loss, diarrhea, and hematochezia. His symptoms were chronic and had lasted for more than 1 year before diagnosis. Inflammatory bowel disease or chronic enteritis due to Salmonella arizonae because of reptile exposure originally were suspected as etiologies of his presentation. The findings of proteinuria, renal failure, and pauci-immune glomerulonephritis on renal biopsy, in conjunction with an elevated c-ANCA titer, confirmed the diagnosis of Wegener’s granulomatosis with associated intestinal vasculitis. This case demonstrates an atypical presentation of chronic duodenitis and jejunitis secondary to Wegener’s granulomatosis, which mimicked inflammatory bowel disease.Keywords: ANCA-associated vasculitis, Wegener’s syndrome, pauci-immune glomerulonephritis, Salmonella arizonae, inflammatory bowel disease

    We present a 29-year-old male with Crohn's disease who developed chronic inflammatory demyelinating polyneuropathy (CIDP) related to infliximab therapy. He developed lower extremity weakness and dysesthesia 3 weeks after a fourth infliximab dose. Laboratory examination revealed an elevated cerebrospinal fluid protein without pleocytosis. The patient initially responded to plasmapheresis therapy with marked symptomatic improvement, but relapsed and was refractory to subsequent treatments with plasmaphereisis, intravenous immunoglobulin, and glucocorticoids. While a causal relationship between infliximab and CIDP cannot be proven, clinicians should monitor Crohn's disease patients who are receiving TNF-α antagonists for neurologic symptoms suggestive of demyelinating disease.

    Full Text Available One of the elements of treatment considering inflammatory bowel diseases is nutritional therapy. The duration of the above-mentioned depends on the prevalence of such symptoms as fever, bowel move-ments, length of the functioning gastrointestinal tract, stoma and intestinal fistula presence. Nutritional therapy is an essential element of successful treatment alongside pharmacological, surgical, and biological therapy, as well as other methods. Crohn's disease and ulcerative colitis considered as chronic diseases, lead towards physical and biopsychosocial disability, being responsible for the reduction in the quality of life.

    Glossopharyngeal and/or vagus nerve involvement is infrequent in patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). We herein report the case of a 69-year-old Japanese woman who presented with muscle weakness and numbness of the extremities with dysphagia. The serum anti-ganglioside GM1 immunoglobulin IgM antibody levels were elevated, and treatment with intravenous immunoglobulin (IVIg) resulted in a dramatic improvement; the weakness, numbness and dysphagia all resolved. However, relapse comprising dysphagia alone occurred on hospital day 26, and treatment with IVIg again proved extremely effective. IVIg therapy can be effective against cranial nerve involvement in cases of CIDP.

    Full Text Available Severe respiratory muscle paralysis and ventilatory failure is rare in chronic inflammatory demyelinating polyneuropathy (CIDP. We report a 14 year child who presented with respiratory failure, bulbar and multiple cranial nerves involvement along with bilateral phrenic nerve paralysis. He was diagnosed with CIDP after electrophysiological evaluation. He required AMBU ventilation for about 4 months (including domiciliary use, after which he recovered significantly. Along with several unusual features of CIDP, this report highlights good example of steady basic intensive care to save lives and rewarding outcome of prolonged respiratory support, provided by AMBU ventilation which is a rather primitive, but inexpensive device.

    We present a 29-year-old male with Crohn's disease who developed chronic inflammatory demyelinating polyneuropathy (CIDP) related to infliximab therapy. He developed lower extremity weakness and dysesthesia 3 weeks after a fourth infliximab dose. Laboratory examination revealed an elevated cerebrospinal fluid protein without pleocytosis. The patient initially responded to plasmapheresis therapy with marked symptomatic improvement, but relapsed and was refractory to subsequent treatments with plasmaphereisis, intravenous immunoglobulin, and glucocorticoids. While a causal relationship between infliximab and CIDP cannot be proven, clinicians should monitor Crohn's disease patients who are receiving TNF-α antagonists for neurologic symptoms suggestive of demyelinating disease.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an uncommon demyelinating disorder with a relapsing and remitting or continuously progressive course. Hypertrophic nerve roots, sometimes associated with gadolinium enhancement, has been reported more commonly in lumbar spine and less commonly in the brachial plexus and cervical roots; however, diffuse involvement of intercostal nerves bilaterally has never been reported previously. We present MRI findings which include diffuse enlargement and mild enhancement of roots and extraforaminal segments of nerves in all segments except a short segment between T12-L2 as well as all the intercostal nerves in a case of CIPD with a 10-year history.

    The diagnosis of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) requires a careful clinical and neurophysiological evaluation, often completed by CSF analysis. In numerous cases, this diagnosis is straightforward and leads to rapid initiation of an immunomodulatory treatment. However, some patients are not diagnosed because of atypical clinical and/or neurophysiological features, and do not benefit from a potentially effective treatment. In this context, a working group was composed with the task of establishing recommendations on diagnostic strategies for CIDP in the main clinical situations where this diagnosis may be suspected. We have summarized these recommendations and tried to present them in the form of a decision-making algorithm.

    Recent research indicates that chronic inflammatory diseases, including allergies and autoimmune and neuropsychiatric diseases, share common pathways of cellular and molecular dysregulation. It was the aim of the International von-Behring-Röntgen Symposium (October 16-18, 2014, in Marburg, Germany) to discuss recent developments in this field. These include a concept of biodiversity; the contribution of urbanization, lifestyle factors, and nutrition (eg, vitamin D); and new mechanisms of metabolic and immune dysregulation, such as extracellular and intracellular RNAs and cellular and mitochondrial stress. Epigenetic mechanisms contribute further to altered gene expression and therefore to the development of chronic inflammation. These novel findings provide the foundation for further development of preventive and therapeutic strategies. PMID:27373325

    Full Text Available Context: Chronic inflammatory demyelinating polyradiculopathy (CIDP is an acquired and autoimmune neuropathy, characterized by a chronic, rapidly progressive, symmetric weakness. In children, abnormal gait is as a first symptom of muscle weakness. Evidence Acquisition: The diagnosis of CIDP is on the basis of clinical characteristics, electrodiagnostic that shows the severity of the disease, lumbar puncture and spine magnetic resonance imaging (MRI. Results: The first-line treatments in childhood CIDP are intravenous immunoglobulin (IVIG, corticosteroids, and plasmapheresis. Response to first-line therapies is usually satisfactory; nevertheless, recommendations regarding the choice of second-line therapy can only be prepared on the basis of the existing practice described in some of the case reports. Conclusions: This review demonstrated the clinical presentation, diagnosis, and treatment of childhood CIDP.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a chronic neuropathy of supposed immune origin. Understanding of its pathophysiology has recently improved, although its causes remain unclear. The classic presentation of CIDP includes sensory and motor symptoms in the distal and proximal segments of the four limbs with areflexia, evolving over more than 8 weeks. Raised protein concentrations in CSF and heterogeneous slowing of nerve conduction are typical of the condition. In addition to this usual phenotype, distribution of symptoms, disease course, and disability can be heterogeneous, leading to underdiagnosis of the disorder. Diagnosis is sometimes challenging and can require use of imaging and nerve biopsy. Steroids and intravenous immunoglobulin are effective, and plasma exchange can be helpful as rescue therapy. The usefulness of immunosuppressants needs to be established. The identification of specific diagnostic markers and new therapeutic strategies with conventional or targeted immunotherapy are needed to improve the outlook for patients with CIDP.

    Chronic inflammatory diseases represent a heterogeneous group of conditions that can affect practically any organ or system. An increasing number of biologic agents have been developed to selectively target the cell populations and signaling pathways involved in chronic inflammation, including cytokines, monoclonal antibodies and engineered receptors. This approach has been remarkably successful in alleviating some of the signs and symptoms of refractory autoimmune diseases. The use of this therapeutic strategy is likely to increase with the introduction of biosimilar agents. The different nature of these biological products makes the comparison of their pharmaceutical and clinical characteristics difficult, including safety and potency and these issues may be particularly relevant in the case of biosimilars. In addition, the heterogeneity of autoimmune diseases and of autoimmune patients, further adds to the complexity of choosing the right drug for each patient and predicting efficacy and safety of the treatment. In this review, we summarize actual knowledge about current biological agents and their use in autoimmune diseases, with a special emphasis for rheumatoid arthritis, inflammatory bowel diseases and psoriasis. The purpose of this analysis is to address the most critical issues raised by the rapid advancements in this field over recent years, and to acknowledge the potentially valuable gains brought about by the increasing availability of these new biologic agents.

    Previous studies have indicated that fluoride (F) can affect testicular toxicity in humans and rodents. However, the mechanism underlying F-induced testicular toxicity is not well understood. This study was conducted to evaluate the sperm quality, testicular histomorphology and inflammatory response in mice followed F exposure. Healthy male mice were randomly divided into four groups with sodium fluoride (NaF) at 0, 25, 50, 100 mg/L in the drinking water for 180 days. At the end of the exposure, significantly increased percentage of spermatozoa abnormality was found in mice exposed to 50 and 100 mg/L NaF. Disorganized spermatogenic cells, vacuoles in seminiferous tubules and loss and shedding of sperm cells were also observed in the NaF treated group. In addition, chronic F exposure increased testicular interleukin-17(IL-17), interleukin-17 receptor C (IL-17RC), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in transcriptional levels, as well as IL-17 and TNF-α levels in translational levels. Interestingly, we observed that F treated group elevated testicular inducible nitric oxide synthase (iNOS) mRNA level and nitric oxide (NO) concentration. Taken together, these results indicated that testicular inflammatory response could contribute to chronic F exposure induced testicular toxicity in mice.

  20. The immunomodulatory properties of Helicobacter pylori confer protection against allergic and chronic inflammatory disorders

    2012-02-01

    Full Text Available Chronic infection with the gastric bacterial pathogen Helicobacter pylori causes gastritis and predisposes carriers to a high risk of developing gastric and duodenal ulcers, gastric cancer and gastric lymphoma, but has also recently been shown to protect against certain allergic and chronic inflammatory disorders. The immunomodulatory properties that allow the bacteria to persist for decades in infected individuals in the face of a vigorous, yet ultimately non-protective, innate and adaptive immune response may at the same time confer protection against allergies, asthma and inflammatory bowel diseases. Experimental evidence from mouse models suggests that H. pylori has evolved to skew the adaptive immune response towards immune tolerance rather than immunity, which promotes persistent infection on the one hand, and inhibits auto-aggressive and allergic T-cell responses on the other. Regulatory T-cells mediating peripheral immune tolerance have emerged as key cellular players in facilitating persistent infection as well as protection from allergies, in both observational studies in humans and experimental work in mice. Recent data suggest that H. pylori actively targets dendritic cells to promote tolerance induction. The findings discussed in this review raise the possibility of harnessing the immunomodulatory properties of H. pylori for the prevention and treatment of allergic and auto-immune diseases, and also provide new insights relevant for H. pylori-specific vaccine development.

    In the recent decades the rapid development of the studies on new methods used in diagnosis, differential diagnosis, and monitoring the treatment of inflammatory bowel diseases has been observed. To the diagnostics of gastrointestinal disorders new methods such as endoscopic capsule and imaging methods including magnetic resonance have been introduced. Markers of inflammation detected in stool play significant role in the diagnostics. To the best known belong calprotectine and lactoferrin, which are produced by neutral granulocytes. In the present review we have presented the clinical usefulness of detection in the stool of calprotectin, lectoferrin, S100A12 protein and pyruvate kinase. Clinical usefulness of these markers were used in diagnosis, assessment of the treatment results, disease relapse and mucosal healing in inflammatory bowel disease. Determination of fecal calprotectin and lactoferrin in the process of mucosal healing in ulcerative colitis or Crohn's disease are of particular value. Confirmation of these results in multicenter prospective trials will enable in the future to reduce the number of control colonoscopies, which in children are performer under general anesthesia.

    Full Text Available Abstract Background Short bowel syndrome (SBS may induce a plethora of clinical symptoms ranging from underweight to nutrient-, vitamin- and electrolyte deficiencies. The objective of this case report is to illustrate how demanding the management of a 60 year old patient with SBS and recurrent joint attacks was for different medical disciplines. Case presentation The patient with SBS presented with a body mass index of 16.5 kg/m2 after partial jejunoileal resection of the small intestine with a six year long history of recurrent pain attacks in multiple peripheral joints, chronic diarrhoea and food intolerances. Pain attacks occurred 4–5 times a week with a median consumption of 15 mg prednisone per day. The interdisciplinary workup after several gastroenterologic, rheumatologic, radiologic, psychiatric and orthopedic consultations is shown including successful treatment steps. Clinical diagnosis revealed no systemic inflammatory disease, but confirmed extreme hypomagnesemia (0.2 mmol/l after reproducible pathological magnesium resorption tests as causative for chronic calcium pyrophosphate crystal inflammatory arthritis (pseudogout, chondrocalcinosis. Multidisciplinary treatment included application of colchicines, parenteral nutrition and magnesium substitution, antiperistaltic agents and avoidance of intolerant foods. Normalization of magnesium levels and a marked remission of joint attacks were achieved after six months with significant reduction of prednisone to 1.5 mg/day. Conclusion Despite the rarity of this condition, it is important to know that hypomagnesaemia may be associated with calcium pyrophosphate crystal inflammatory arthritis (chondrocalcinosis and that SBS patients may be prone to develop extreme hypomagnesaemia causing recurrent joint attacks without systemic inflammation.

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

    Our laboratory previously developed a novel neuropathic and inflammatory facial pain model for mice referred to as the Trigeminal Inflammatory Compression (TIC) model. Rather than inducing whole nerve ischemia and neuronal loss, this injury induces only slight peripheral nerve demyelination triggering long-term mechanical allodynia and cold hypersensitivity on the ipsilateral whisker pad. The aim of the present study is to further characterize the phenotype of the TIC injury model using specific behavioral assays (i.e. light-dark box, open field exploratory activity, and elevated plus maze) to explore pain- and anxiety-like behaviors associated with this model. Our findings determined that the TIC injury produces hypersensitivity 100% of the time after surgery that persists at least 21 weeks post injury (until the animals are euthanized). Three receptive field sensitivity pattern variations in mice with TIC injury are specified. Animals with TIC injury begin displaying anxiety-like behavior in the light-dark box preference and open field exploratory tests at week eight post injury as compared to sham and naïve animals. Panic anxiety-like behavior was shown in the elevated plus maze in mice with TIC injury if the test was preceded with acoustic startle. Thus, in addition to mechanical and cold hypersensitivity, the present study identified significant anxiety-like behaviors in mice with TIC injury resembling the clinical symptomatology and psychosocial impairments of patients with chronic facial pain. Overall, the TIC injury model's chronicity, reproducibility, and reliability in producing pain- and anxiety-like behaviors demonstrate its usefulness as a chronic neuropathic facial pain model.

    Chronic inflammatory disorders are thought to arise due to an interplay between predisposing host genetics and environmental factors. For example, the onset of inflammatory bowel disease is associated with enteric proteobacterial infection, yet the mechanistic basis for this association is unclear. We have shown previously that genetic defiency in TLR1 promotes acute enteric infection by the proteobacteria Yersinia enterocolitica. Examining that model further, we uncovered an altered cellular immune response that promotes the recruitment of neutrophils which in turn increases metabolism of the respiratory electron acceptor tetrathionate by Yersinia. These events drive permanent alterations in anti-commensal immunity, microbiota composition, and chronic inflammation, which persist long after Yersinia clearence. Deletion of the bacterial genes involved in tetrathionate respiration or treatment using targeted probiotics could prevent microbiota alterations and inflammation. Thus, acute infection can drive long term immune and microbiota alterations leading to chronic inflammatory disease in genetically predisposed individuals.

    2014-03-01

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a chronic and often disabling sensory motor neuropathy postulated as caused by an immune attack against peripheral nerve myelin. In addition to a classic sensory–motor polyneuropathy, other phenotypes of CIDP have been described including the Lewis- Sumner syndrome, distal acquired demyelinating symmetric (DADS) neuropathy, pure motor CIDP, pure sensory CIDP including chronic immune sensory polyradiculopathy (CISP), and focal CIDP. These phenotypes are currently considered to be variants of CIDP, even if the possibility that they represent different demyelinating neuropathies cannot be fully excluded considering differences in their response to therapy. Several data support the role of the immune system in the pathogenesis of CIDP even if the precise targets and actors (antibodies and lymphocytes) of this immune response remain uncertain. Recent studies have shown that the therapeutic response may differ in patients with peculiar clinical presentations supporting the hypothesis that different pathogenetic mechanisms may underlie the heterogeneity of CIDP. The majority of patients with CIDP show improvement after immune therapies including corticosteroids, plasma exchange, and high-dose intravenous immunoglobulin (IVIg). It remains unclear why none of the other immune therapies that were reported to be variably effective in other immune disorders proved to be effective also in CIDP.

  8. Anti-Inflammatory and Antinociceptive Effects of Salbutamol on Acute and Chronic Models of Inflammation in Rats: Involvement of an Antioxidant Mechanism

    Directory of Open Access Journals (Sweden)

    Hulya Uzkeser

    2012-01-01

    Full Text Available The possible role of β-2 adrenergic receptors in modulation of inflammatory and nociceptive conditions suggests that the β-2 adrenergic receptor agonist, salbutamol, may have beneficial anti-inflammatory and analgesic effects. Therefore, in this study, we induced inflammatory and nociceptive responses with carrageenan-induced paw edema or cotton-pellet-induced granuloma models, both of which result in oxidative stress. We hypothesized that salbutamol would prevent inflammatory and nociceptive responses by stimulating β-2 adrenergic receptors and the prevention of generation of ROS during the acute inflammation process in rats. Both doses of salbutamol used in the study (1 and 2 mg/kg effectively blocked the acute inflammation and inflammatory nociception induced by carrageenan. In the cotton-pellet-induced granuloma test, both doses of salbutamol also significantly decreased the weight of granuloma tissue on the cotton pellets when compared to the control. Anti-inflammatory and analgesic effects of salbutamol were found to be comparable with those of indomethacin. Salbutamol decreased myeloperoxidase (MPO activity and lipid peroxidation (LPO level and increased the activity of superoxide dismutase (SOD and level of glutathione (GSH during the acute phase of inflammation. In conclusion, salbutamol can decrease acute and chronic inflammation, possibly through the stimulation of β-2 adrenergic receptors. This anti-inflammatory effect may be of significance in asthma treatment, where inflammation also takes part in the etiopathology. This study reveals that salbutamol has significant antioxidative effects, which at least partially explain its anti-inflammatory capabilities. These findings presented here may also shed light on the roles of β-2 adrenergic receptors in inflammatory and hyperalgesic conditions.

    An evaluation of histological findings in full-thickness biopsies from the gastrointestinal tract (GIT) and extraintestinal samples of 43 cats with chronic GIT disease signs was performed. In the majority of cases (46.5%) inflammatory bowel disease, ie, lymphocytic-plasmacytic enteritis/colitis (32.6%), eosinophilic gastroenterocolitis (11.6%) and mixed inflammatory infiltration (2.3%), was diagnosed. Furthermore, in four animals non-inflammatory mucosal band-shaped fibrosis (9.3%), and in 10 cats (23.3%) a diffuse lymphoma, was found. Six cats displayed only a gastritis (7.0%) or lymphangiectasia (7.0%), respectively. In two cats a mast cell tumour (4.7%) was diagnosed. In one cat no histopathological lesions were found. The availability of transmural biopsies from all segments of the intestine and the collection of extraintestinal samples, especially mesenteric lymph nodes, is especially helpful for diagnosing intestinal tumours such as lymphomas and tumours of mast cell origin.

Clinically, rosacea can be categorized into papulopustular, erythematotelangiectatic, ocular, and phymatous rosacea. However, the phenotypic presentations of rosacea are more heterogeneous. Although the pathophysiology of rosacea remains to be elucidated, immunologic alterations and neurovascular dysregulation are thought to have important roles in initiating and strengthening the clinical manifestations of rosacea. In this article, we present the possible molecular mechanisms of rosacea based on recent laboratory and clinical studies. We describe the genetic predisposition for rosacea along with its associated diseases, triggering factors, and suggested management options in detail based on the underlying molecular biology. Understanding the molecular pathomechanisms of rosacea will likely aid toward better comprehending its complex pathogenesis.

    Chronic relapsing inflammatory optic neuropathy (CRION) is an entity that was described in 2003. Early recognition of patients suffering from CRION is relevant because of the associated risk for blindness if treated inappropriately. It seems timely to have a clinical review on this recently defined entity. A systematic literature review, irrespective of language, retrieved 22 case series and single reports describing 122 patients with CRION between 2003 and 2013. We review the epidemiology, diagnostic workup, differential diagnosis, and treatment (acute, intermediate, and long term) in view of the collective data. These data suggest that CRION is a distinct nosological entity, which is seronegative for anti-aquaporin four auto-antibodies and recognized by and managed through its dependency on immuno-suppression. Revised diagnostic criteria are proposed in light of the data compromising a critical discussion of relevant limitations.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired, autoimmune peripheral neuropathy. Systemic lupus erythematosus (SLE) is a multisystemic, autoimmune disease that can affect the central nervous system in about 40% of patients, with prevalence and incidence unknown in the pediatric population due to lack of multicenter studies. We report the case of a 13-year-old Mexican boy, diagnosed with CIDP at the onset of SLE, beginning with progressive muscle weakness of lower and upper limbs, without affection of the central nervous system. The patient had positive ANA, antiDNAdc, antiBeta2glycoprotein, anti-cardiolipin, ANCA-C and X. He received intravenous immunoglobulin, cyclophosphamide, steroids, and azathioprine and showed clinical improvement. It is important to take into account the presence of peripheral neurological disorders in patients with pediatric SLE, considering CIDP as an uncommon presentation, making the diagnosis important for better treatment and evolution.

  15. Treatment of Chronic Inflammatory Demyelinating Polyneuropathy: From Molecular Bases to Practical Considerations

    Full Text Available Chronic inflammatory demyelinating polyneuropathy (CIDP is an autoimmune disease of the peripheral nervous system, in which both cellular and humoral immune responses are involved. The disease is clinically heterogeneous with some patients displaying pure motor form and others also showing a variable degree of sensory dysfunction; disease evolution may also differ from patient to patient, since monophasic, progressive, and relapsing forms are reported. Underlying such clinical variability there is probably a broad spectrum of molecular dysfunctions that are and will be the target of therapeutic strategies. In this review we first explore the biological bases of current treatments and subsequently we focus on the practical management that must also take into account pharmacoeconomic issues.

    Full Text Available The quantitative ultrasound characteristics (USC of the median, ulnar nerve at different levels and the spinal nerves in patients with multifocal motor neuropathy (MMN; n=13; 40,4 ± 12,6 years old and chronic inflammatory demyelinating polyneuropathy (CIDP; n = 7; 47,3 ± 11,2 year old did not reveal statistical difference in cross sectional area (CSA between analyzed groups. Patients with MMN have more pronounced asymmetry of CSA in comparison with CIDP patients which have a symmetrical pattern of diffuse nerve involvement. Quantitative USC has shown to be not informative enough in differentiation of MMN and CIDP. The qualitative analysis (QA according to 3 described types of nerve changes has shown that CIDP is characterized by the prevalence of type 3 pattern (85.8 % while MMN – by type 2 (69.2 %. The sensitivity and specificity of proposed QA patterns in nerve USC need to be analyzed in additional investigations.

    Full Text Available Pediatric chronic inflammatory demyelinating polyneuropathy (CIDP is an uncommon acquired disorder of unknown cause, presumed to have an immunological basis. We report 20 patients seen at Children′s Hospital Los Angeles over a period of 10 years. The outcome of our patients was favorable in a vast majority with good response to various treatments instituted. However, residual neurologic deficit was common. The choice of treatment modality was empirical and selected by the treating neurologist. Intravenous immunoglobulin (IVIG and corticosteroids were most commonly utilized for treatment. Plasmapheresis, mycophenolate mofetil, rituximab, cyclophosphamide, azathioprine, and abatacept were added if the patients were refractory to IVIG or became corticosteroid dependent. The spectrum of disease severity ranged from a single monophasic episode, to multiphasic with infrequent relapses with good response to IVIG, to progressive disease refractory to multiple therapies.

    Hypogeusia, a condition with diminished sense of taste, is caused by several conditions, including zinc deficiency and as a side-effect of drugs, but is not common in neurological disorders. A 55-year-old Japanese man with a 30-year history of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) presented with hypogeusia during hospitalization for a recurrence of CIDP. The hypogeusia improved after treatment with high-dose intravenous methylprednisolone (HIMP). Two years later, hypogeusia developed again. A complete taste deficit was revealed by a filter paper test. Brain MRI showed enhancement of the bilateral facial nerve ganglia. Hypogeusia was partially ameliorated after extensive immunosuppressive therapy with repeated HIMP and plasma exchange. Improvement was more prominent in the area innervated by the chorda tympani nerve than that innervated by the glossopharyngeal nerve. To our knowledge, this is the first report of recurrent hypogeusia, which might be caused by cranial nerve injury associated with CIDP.

    2012-05-01

    Full Text Available The inflammatory bowel diseases (IBD, including Crohn’s disease and ulcerative colitis, are chronic inflammatory disorders of the intestine. The prevalence in the United States is greater than 200 cases per 100,000, with the total number of IBD patients between 1 and 1.5 million. Crohn’s disease may affect all parts of the gastrointestinal tract, from mouth to anus, but most commonly involves the distal part of the small intestine or ileum, and colon. Ulcerative colitis results in colonic inflammation that can affect the rectum only, or can progress proximally to involve part of or the entire colon. Clinical symptoms include diarrhea, abdominal pain, gastrointestinal bleeding and weight loss. A serious long-term complication of chronic inflammation is the development of colorectal cancer. A genetic basis for IBD had long been recognized based on the increased familial risk. However, significant discordance for Crohn’s disease in twins, and a much less robust phenotypic concordance for ulcerative colitis, suggested additional factors play a role in disease pathogenesis, including environmental factors. In the past several years, progress in understanding the molecular basis of IBD has accelerated, beginning with the generation of animal models of colitis and progressing to the identification of specific genetic markers from candidate gene, gene linkage and genome wide association analyses . Genetic studies have also resulted in the recognition of the importance of environmental factors, particularly the crucial role of the gut microbiota in Crohn’s disease and ulcerative colitis. Altered immune responses to the normal intestinal flora are key factors in IBD pathogenesis. In this Research Topic, the genetic basis of IBD, the genetic and cellular alterations associated with colitis-associated colon cancer, and the emerging role of the intestinal microbiota and other environmental factors will be reviewed.

    Background. Auricular point acupressure (APA) is a promising treatment for pain management. Few studies have investigated the physiological mechanisms of APA analgesics. Method. In this pilot randomized clinical trial (RCT), a 4-week APA treatment was used to manage chronic low back pain (CLBP). Sixty-one participants were randomized into a real APA group (n = 32) or a sham APA group (n = 29). Blood samples, pain intensity, and physical function were collected at baseline and after 4 weeks of treatment. Results. Subjects in the real APA group reported a 56% reduction of pain intensity and a 26% improvement in physical function. Serum blood samples showed (1) a decrease in IL-1β, IL-2, IL-6, and calcitonin gene-related peptide [CGRP] and (2) an increase in IL-4. In contrast, subjects in the sham APA group (1) reported a 9% reduction in pain and a 2% improvement in physical function and (2) exhibited minimal changes of inflammatory cytokines and neuropeptides. Statistically significant differences in IL-4 and CGRP expression between the real and sham APA groups were verified. Conclusion. These findings suggest that APA treatment affects pain intensity through modulation of the immune system, as reflected by APA-induced changes in serum inflammatory cytokine and neuropeptide levels.

    Full Text Available BACKGROUND: Tobacco smoking is the main risk factor of chronic obstructive pulmonary disease (COPD but not all smokers develop the disease. An abnormal pulmonary and systemic inflammatory response to smoking is thought to play a major pathogenic role in COPD, but this has never been tested directly. METHODS: We studied the systemic biomarker and leukocyte transcriptomic response (Affymetrix microarrays to smoking exposure in 10 smokers with COPD and 10 smokers with normal spirometry. We also studied 10 healthy never smokers (not exposed to smoking as controls. Because some aspects of COPD may differ in males and females, and the inflammatory response to other stressors (infection might be different in man and women, we stratified participant recruitment by sex. Differentially expressed genes were validated by q-PCR. Ontology enrichment was evaluated and interaction networks inferred. RESULTS: Principal component analysis identified sex differences in the leukocyte transcriptomic response to acute smoking. In both genders, we identified genes that were differentially expressed in response to smoking exclusively in COPD patients (COPD related signature or smokers with normal spirometry (Smoking related signature, their ontologies and interaction networks. CONCLUSIONS: The use of an experimental intervention (smoking exposure to investigate the transcriptomic response of peripheral leukocytes in COPD is a step beyond the standard case-control transcriptomic profiling carried out so far, and has facilitated the identification of novel COPD and Smoking expression related signatures which differ in males and females.

    Mycobacterium ulcerans (M. ulcerans) causes Buruli ulcer, a very debilitating disease that affects the skin and other tissues. The disease occurs mainly in children in sub-Sahara Africa. While contracture, fibrosis and functional limitation of range of motion are frequent complications of Buruli ulcer, no fundamental or clinical studies have investigated the impact of M. ulcerans infections on skeletal muscle. In the present study, we subcutaneously infected mice in the proximity of the right biceps muscle to evaluate the histological, biochemical and functional impact of M. ulcerans on skeletal muscles. The concentration of mast cells decreased but the number of neutrophils and macrophages increased steadily in proximate-infected biceps muscles. Pro- and anti-inflammatory cytokines as well as fibrogenic growth factor mRNA also increased. Significantly more membrane damage and fibrosis occurred in proximate-infected biceps muscles than in control and sham muscles. Passive biomechanical testing also revealed that the presence of M. ulcerans increased muscle stiffness. These findings show for the first time that M. ulcerans can induce local and chronic inflammatory responses in skeletal muscles that are associated with muscle fiber damage and fibrosis.

    We report a case of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) concomitant with acquired von Willebrand syndrome. A 33-year-old man developed motor and sensory polyneuropathy with electrophysiological conduction slowing. At this time, M-protein was absent He was diagnosed with CIDP and received intravenous immunoglobulin and subsequent oral corticosteroids, which resulted in almost complete remission for over 10 years. At the age of 44, he presented with chronic anemia. Laboratory tests and colonoscopy revealed that he had acquired von Willebrand syndrome with monoclonal gammopathy of undetermined significance (IgG lambda type) and colon cancer. Bleeding symptoms were.resolved with intravenous immunoglobulin, but not with supplementation of factor VIII. Shortly after successful excision of the cancer, CIDP and acquired von Willebrand syndrome simultaneously recurred. Intravenous immunoglobulin produced rapid improvement of both neurological and hematological abnormalities. Concurring CIDP and acquired von Willebrand syndrome in the present case may indicate that the conditions have a partly common immunological background including monoclonal gammopathy and a potential common autoantibody-mediated mechanism. Alternatively, dysfunction of von Willebrand factor may increase blood-nerve barrier permeability, inducing the recurrence of CIDP.

    The clinical presentation, disease course, response to treatment, and long-term outcome of thirty childhood chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) patients are presented representing the largest cohort reported to date. Most children (60%) presented with chronic (>8-weeks) symptom-onset while a smaller proportion showed sub-acute (4-8 weeks) or acute (''GBS-like''; CIDP series providing a comprehensive review of 143 childhood CIDP cases. The combined initial or first-line treatment response across all studies was favourable for IVIG (79% patients) and corticosteroids (84% patients). Response to first-line plasma exchange was poor (only 14% patients improved) although it may offer some transient or partial benefit as an adjuvant or temporary therapy for selected patients. The combined long-term outcome of our cohort and the literature reveals a favourable prognosis for most patients. The combined modified Rankin scale decreased from 3.7 (at presentation) to 0.7 (at last follow-up). This review provides important data pertaining to clinical course, treatment response and long-term outcome of this relatively uncommon paediatric autoimmune disease.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP)-related research has made progress in the field of pathogenesis, genetics, and treatment. The number of circulating CD4(+) CD25(+) T-regulatory cells was shown to be reduced in CIDP patients. Increased frequency of genotype GA13-16 of the SH2D2A gene encoding for a T-cell-specific adapter protein in CIDP patients may result in a defective control and elimination of autoreactive T cells. IVIg treatment has been shown to increase numbers and function of peripheral CD4(+) CD25(+) T-regulatory cell in a mouse model. These findings shed new light on the understanding of why peripheral tolerance is breached in CIDP patients and why the disease becomes chronic and adds another possible mechanism of action of intravenous immunoglobulin to the already long list. Long-term effectiveness of IVIg has now been proven. Subcutaneous immunoglobulin could be an alternative for IVIg, but this has to be explored further in well-designed trials. Autologous stem cell transplantation has been tried in refractory patients, but larger trials are necessary to assess safety and effect of this treatment.

    The chronic inflammatory state in sickle cell anemia (SCA) is associated with several factors such as the following: endothelial damage; increased production of reactive oxygen species; hemolysis; increased expression of adhesion molecules by leukocytes, erythrocytes, and platelets; and increased production of proinflammatory cytokines. Genetic characteristics affecting the clinical severity of SCA include variations in the hemoglobin F (HbF) level, coexistence of alpha-thalassemia, and the haplotype associated with the HbS gene. The different haplotypes of SCA are Bantu, Benin, Senegal, Cameroon, and Arab-Indian. These haplotypes are associated with ethnic groups and also based on the geographical origin. Studies have shown that the Bantu haplotype is associated with higher incidence of clinical complications than the other haplotypes and is therefore considered to have the worst prognosis. This study aimed to evaluate the profile of the proinflammatory cytokines interleukin-6, tumor necrosis factor-α, and interleukin-17 in patients with SCA and also to assess the haplotypes associated with beta globin cluster S (HBB(*)S). We analyzed a total of 62 patients who had SCA and had been treated with hydroxyurea; they had received a dose ranging between 15 and 25 (20.0±0.6)mg/kg/day for 6-60 (18±3.4)months; their data were compared with those for 30 normal individuals. The presence of HbS was detected and the haplotypes of the beta S gene cluster were analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Our study demonstrated that SCA patients have increased inflammatory profile when compared to the healthy individuals. Further, analysis of the association between the haplotypes and inflammatory profile showed that the levels of IL-6 and TNF-α were greater in subjects with the Bantu/Bantu haplotype than in subjects with the Benin/Benin haplotype. The Bantu/Benin haplotype individuals had lower levels of cytokines than those with

    Degenerative changes of the endometrium are directly related to age and fertility in mares. Chronic degenerative endometritis (CDE) is correlated with uterine fluid retention and reduced ability to clear uterine inflammation. Recent research in the areas of equine surgery and sports medicine has shown that platelet-rich plasma (PRP) treatment acts as an immunomodulator of the inflammatory response. Therefore, the aim of this study was to determine if the uterine infusion of PRP could modulate the local inflammatory response and modify the intrauterine NO concentrations after artificial insemination (AI) in both normal mares and those with CDE. Thirteen mares with endometrium classified as grade III on the histology (mares with CDE) and eight mares with endometrial histological classification I or II-a normal mares were selected to investigate the effect of PRP therapy. The mares were inseminated with fresh semen in two consecutive cycles in a crossover study design. Thereby, each mare served as its own control and the treatment was performed with intrauterine PRP infusion four hours after AI. The percentage of neutrophils in uterine cytology (CIT, %), uterine fluid accumulation observed on ultrasonography (FLU, mm) and nitric oxide concentration of uterine fluid (NO, μM) were analyzed before and 24 hours after AI. The results reported that mares with CDE (CIT, 68.3 ± 3.27, FLU, 10.7 ± 1.61) have a higher (P  0.05) between categories of mares. In treated cycles with PRP, the intrauterine inflammatory response decrease (P < 0.05) in CDE mares (CDE: CIT, 31.4 ± 6.48, FLU, 5.5 ± 1.28; normal mares: CIT, 13.5 ± 4.31, FLU, 0) when compared with nontreated cycle (CDE: CIT, 68.3 ± 3.27, FLU, 10.7 ± 1.61; NM: CIT, 24.4 ± 3.56, FLU, 0), but did not modify NO concentrations in uterine fluid. Thus, we can conclude that PRP was effective in modulating the exacerbated uterine inflammatory response to semen in mares with CDE but did not reduce NO

    Full Text Available Background: Chronic pain, or sometimes referred to as persistent pain, reduces the life quality of patients who are suffering from chronic diseases such as inflammatory diseases, cancer and diabetes. Hence, herbal medicines draw many attentions and have been shown effective in the treatment or relief of pain. Methods and Results: Here in this study, we used the CFA-injected rats as a sustainable pain model to test the anti-inflammatory and analgesic effect of nutmeg oil, a spice flavor additive to beverages and baked goods produced from the seed of Myristica fragrans tree. Conclusions: We have demonstrated that nutmeg oil could potentially alleviate the CFA-injection induced joint swelling, mechanical allodynia and heat hyperanalgesia of rats through inhibition of COX-2 expression and blood substance P level, which made it possible for nutmeg oil to be a potential chronic pain reliever.

    Inflammatory mediators alter the local environment of tumors, known as the tumor microenvironment. Mechanistically, chronic inflammation induces DNA damage, but understanding this hazard may help in the search for new chemopreventive agents for gastrointestinal (GI) cancer which attenuate inflammation. In the clinic, GI cancer still remains a major cause of cancer-associated mortality, chemoprevention with anti-inflammatory agents is thought to be a realistic approach to reduce GI cancer. Proton pump inhibitors, monoclonal antibodies targeting tumor necrosis factor-alpha, anti-sense targeted smad7 and non-steroidal anti-inflammatory agents have been investigated for their potential to prevent inflammation-based GI cancer. Besides these, a wide variety of natural products have also shown potential for the prevention of GI cancer. In this review, the authors will provide insights to explain the mechanistic connection between inflammation and GI cancer, as well as describe a feasible cancer prevention strategy based on anti-inflammatory treatments.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an inflammatory disease of the peripheral nervous system that is probably autoimmune in origin. Different components of the adaptive and innate immunity may be responsible for the aberrant response towards nerve antigens. To investigate this, we examined lymphocyte subsets and regulatory T cell (Treg) function in the blood of CIDP patients, healthy controls (HC) and subjects with non-immune mediated neuropathies (other neuropathies, ON). We used flow cytometry to determine the frequency of monocytes, B cells, natural killer (NK) and NK-T cells, total and activated CD4(+) and CD8(+) T cells, effector memory and central memory CD4(+) and CD8(+) T cells, and CD4(+)CD25(high)Foxp3(+) Tregs. Treg function was studied after polyclonal stimulation and antigen specific stimulation with myelin protein peptides in CIDP and HC. There was an increased frequency of monocytes (p = 0.02) and decreased frequency of NK cells (p = 0.02) in CIDP compared with HC but not ON. There were no significant differences in other populations. Treg function was impaired in CIDP compared to HC (p = 0.02), whilst T cell proliferation to myelin protein peptides before and after depletion of Tregs was not different between patients and controls. This study shows increased circulating monocytes and reduced NK cells in CIDP. Although Treg frequency was not altered, we confirm that Tregs display a defect of suppressive function. Myelin protein peptides were not the target of the altered peripheral regulation of the immune response. The mechanisms of peripheral immune tolerance in CIDP and their relevance to the pathogenesis deserve further exploration.

    Full Text Available OBJECTIVE: The aim of the present study was to evaluate the effect of 8 weeks of aerobic exercise training on cardiac functioning and remodeling and on the plasma levels of inflammatory cytokines in chronic heart failure rats. METHODS: Wistar rats were subjected to myocardial infarction or sham surgery and assigned to 4 groups: chronic heart failure trained (n = 7, chronic heart failure sedentary (n = 6, sham trained (n = 8 and sham sedentary (n = 8. Four weeks after the surgical procedures, the rats were subjected to aerobic training in the form of treadmill running (50 min/day, 5 times per week, 16 m/min. At the end of 8 weeks, the rats were placed under anesthesia, the hemodynamic variables were recorded and blood samples were collected. Cardiac hypertrophy was evaluated using the left ventricular weight/body weight ratio, and the collagen volume fraction was assessed using histology. RESULTS: The chronic heart failure trained group showed a reduction in left ventricular end-diastolic pressure, a lower left ventricular weight/body weight ratio and a lower collagen volume fraction compared with the chronic heart failure sedentary group. In addition, exercise training reduced the plasma levels of TNF-α and IL-6 and increased the plasma level of IL-10. CONCLUSION: An 8-week aerobic exercise training program improved the inflammatory profile and cardiac function and attenuated cardiac remodeling in chronic heart failure rats.

  17. Aspirin or Nonsteroidal Anti-inflammatory Drug-Exacerbated Chronic Rhinosinusitis.

    2016-01-01

    Aspirin (ASA)-exacerbated respiratory disease (AERD) is characterized by upper airway congestion due to eosinophilic inflammation of the nasal and sinus membranes and nasal polyposis, associated with increased leukotriene production that is further accentuated by ASA or other nonsteroidal anti-inflammatory drug (NSAID) ingestion. It occurs in 5% to 10% of subjects with chronic rhinosinusitis (CRS) and in 15% to 40% of those with nasal polyposis. Although AERD with CRS is usually associated with asthma, this is not always the case. The eosinophilic airway inflammation and symptoms precede clinical reactions to ASA or other NSAIDs, but ultimately affected subjects experience worsening of symptoms with ingestion of ASA/NSAIDs. The endotypic mechanism for this worsening is related to a chronic increase in leukotriene and a decrease in prostaglandin production, particularly prostaglandin E2, that is further aggravated by the inhibition of cycloxgenase I. IgE does not likely play a role in the pathogenesis of the disease although nasal and sinus staphylococcal infection increases local IgE level and may increase total IgE and specific IgE levels. Genetic studies suggest that multiple genes may be involved, but the genetic abnormalities may differ in affected subjects from different ethnicities and candidate genes have not been confirmed in multiple studies. Genome-wide association studies have not been revealing. The phenotype is recognized by the mucosal inflammation and worsening of symptoms acutely with ASA/NSAID. There is clinical improvement with ASA desensitization followed by regular ingestion of ASA or other NSAIDs. Further understanding of this unique phenotype and endotype of CRS will likely improve the understanding of other eosinophilic airway diseases. PMID:27393773

  18. Evaluation of the inflammatory activity in chronic osteomyelitis. Contribution of the scintigraphy with polyclonal antibodies

    International Nuclear Information System (INIS)

    Active chronic osteomyelitis or complicating osteomyelitis (superimposed on diseases that changes the normal bone structure fractures, post-surgery, prosthesis) can be difficult to diagnose by anatomic radiological imaging modalities, like plain radiograph and CT. These diseases frequently cause also increased bone remodeling, leading to nonspecific uptake of Tc-99m-bone scan agents and gallium-67. New radiopharmaceuticals with greater inflammation/infection avidity and specificity are being developed, including the nonspecific polyclonal immunoglobulin (IgG) labeled with technetium-99. Tc-99m-IgG may be available as a ready to use kit, with no reported side effects, low patient absorbed radiation dose and low cost. The mechanism of IgG uptake at the inflammation site has not been fully elucidated yet. Specific (receptor linking, physico-chemical immunoglobulin properties) and nonspecific mechanisms (enhanced vascular permeability and macromolecular exudate) has been suggested. IgG scintigraphy results are affected by the isotope, labeling procedure adopted and characteristics of the inflammatory focus. Nineteen patients with suspected osteomyelitis (active chronic osteomyelitis or violated bone osteomyelitis) were studied by Tc-99m-IgG scintigraphy (directly labeled polyclonal immunoglobulin, Sandoglobuilina - Sandoz). All patients also underwent standard three-phase bone scintigraphy using methylene diphosphonate (Tc-99m-MDP), gallium-67 scintigraphy and plain radiographs. Infection was found in 8 sites. Sensitivity and specificity for Tc-99m-MDP, gallium-67 and Tc 99m-IgG scintigraphy were, respectively, 88 and 36%, 75 and 73%,88 and 82%. All patients with false positive IgG scintigraphies had previous surgery. Other current scintigraphic procedures used in the diagnosis of osteomyelitis are also reviewed. (author)

    Full Text Available Abstract Background Experimental evidences suggest an increased collagen deposition in inflammatory bowel diseases (IBD. In particular, large amounts of collagen type I, III and V have been described and correlated to the development of intestinal fibrotic lesions. No information has been available until now about the possible increased collagen deposition far from the main target organ. In the hypothesis that chronic inflammation and increased collagen metabolism are reflected also in the systemic circulation, we aimed this study to evaluate the effects on left ventricular wall structure by assessing splancnic and systemic collagen metabolism (procollagen III assay, deposition (ultrasonic tissue characterization, and cardiac function (echocardiography in patients with different long standing history of IBD, before and after surgery. Methods Thirty patients affected by active IBD, 15 with Crohn and 15 with Ulcerative Colitis, submitted to surgery will be enrolled in the study in a double blind fashion. They will be studied before the surgical operation and 6, 12 months after surgery. A control group of 15 healthy age and gender-matched subjects will also be studied. At each interval blood samples will be collected in order to assess the collagen metabolism; a transthoracic echocardiogram will be recorded for the subsequent determination of cardiac function and collagen deposition. Discussion From this study protocol we expect additional information about the association between IBD and cardiovascular disorders; in particular to address the question if chronic inflammation, through the altered collagen metabolism, could affect left ventricular structure and function in a manner directly related to the estimated duration of the disease.

    Most human diseases, including trauma, atherosclerosis, and malignancy, can be characterized by either an overexuberant inflammatory response or an inadequate immunologic response. As our understanding of the mechanisms underlying these inflammatory aberrations improves, so should our approach to the patient. The development of novel technologies capable of exploiting inflammatory mediators will undoubtedly play a role in future patient-directed therapies. Trauma surgeons are uniquely positioned to usher in a new era of patient diagnostics and patient-directed therapies based on an understanding of the immune system's response to stimuli. These improvements are likely to affect not only trauma care but all aspects of medicine. PMID:26304513

    Objective The objective of this case–control study was to quantify the immune responsiveness in individuals with type 2 diabetes (T2D) as compared with patients without diabetes (NT2D) diagnosed with periodontitis. Research Design and Methods Peripheral blood was collected from 20 patients with moderate-to-severe chronic periodontitis (10 T2D, 10 NT2D). Blood samples were stimulated with ultrapure Porphyromonas gingivalis and Escherichia coli lipopolysaccharide (LPS) for 24 hours. 14 cytokines/chemokines were quantified in culture supernatants using multiplex technology. Results T2D individuals demonstrated higher unstimulated levels of interleukin 6 (IL-6), IL-1β, tumor necrosis factor α, interferon γ, IL-10, IL-8, macrophage inflammatory protein 1α (MIP1α), and 1β (MIP1β), and higher stimulated levels of IL-6, IL-8, IL-10, MIP1α and MIP1β, along with lower unstimulated and stimulated levels of granulocyte-macrophage colony-stimulating factor (GM-CSF) when compared with NT2D (pperiodontitis, patients with T2D seem to have an enhanced LPS-induced immune responsiveness than individuals without diabetes, which correlates with periodontal disease severity, concomitant with a less robust GM-CSF response. This data may in part explain the higher predisposition to periodontitis in this population. PMID:27651910

    Full Text Available Whereas an evaluation of quality of life and possible impacts on the mental state of a patient may help to evaluate the evolution of chronic inflammatory demyelinating polyneuropathy (CIDP, the aim of this study was to study the psychological profile of patients, and evaluate quality of life associated with the disease. Method 41 patients were evaluated using a Mini-Mental State Examination (MMSE and a Short-Form Health Survey (SF-36. Results The mean age of the patients was 50.6 years, 63.4% men. Of the participants, 65.9% had other health problems, 39% reported needing help with activities of daily living, 49% slept less than 8 hours per night, and 34.1% complained of some memory deficit. The average MMSE score was 26. Impairment of functional capacity and pain were the more important altered health states. Conclusion CIDP has important social and economic impacts, owing to functional impairments that can lead to professional and personal limitations.

    Rossella Spataro

    2015-01-01

    Full Text Available We describe a patient with chronic inflammatory demyelinating polyneuropathy (CIDP in which an adduction deficit and ptosis in the left eye presented several years before the polyneuropathy. A 52-year-old man presented with a 14-year history of unremitting diplopia, adduction deficit, and ptosis in the left eye. At the age of 45 a mild bilateral foot drop and impaired sensation in the four limbs appeared, with these symptoms showing a progressive course. The diagnostic workup included EMG/ENG which demonstrated reduced conduction velocity with bilateral and symmetrical sensory and motor involvement. Cerebrospinal fluid studies revealed a cytoalbuminologic dissociation. A prolonged treatment with corticosteroids allowed a significant improvement of the limb weakness. Diplopia and ptosis remained unchanged. This unusual form of CIDP presented as a long-lasting isolated cranial nerve palsy. A diagnostic workup for CIDP should therefore be performed in those patients in which an isolated and unremitting cranial nerve palsy cannot be explained by common causes.

    The purpose of this study was to assess the clinical feasibility of diffusion tensor imaging (DTI) for the evaluation of peripheral nerves in patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). Using a 3-T magnetic resonance imaging scanner, we obtained DTI scans of the tibial nerves of 10 CIDP patients and 10 sex- and age-matched healthy volunteers. We prepared fractional anisotropy (FA) maps, measured the FA values of tibial nerves, and compared these values in the two study groups. In nine patients, we also performed tibial nerve conduction studies and analyzed the correlation between the FA values and parameters of the nerve conduction study. The tibial nerve FA values in CIDP patients (median 0.401, range 0.312-0.510) were significantly lower than those in healthy volunteers (median 0.530, range 0.469-0.647) (Mann-Whitney test, p < 0.01). They were significantly correlated with the amplitude of action potential (Spearman correlation coefficient, p = 0.04, r = 0.86) but not with nerve conduction velocity (p = 0.79, r = 0.11). Our preliminary data suggest that the noninvasive DTI assessment of peripheral nerves may provide useful information in patients with CIDP. (orig.)

    Perforin (PRF) has a key role in the function of cytotoxic T and natural killer cells. Rare variations of PRF1 predispose to autoimmunity. Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an autoimmune disease of the peripheral nervous system, involving defective lymphocyte apoptosis. The aim of this study was to investigate the role of PRF1 in CIDP. The entire coding region of PRF1 was sequenced in 94 patients and 158 controls. We found three missense variations leading to amino acid substitutions and one nonsense variation resulting in a premature stop codon. All variations would decrease PRF activity. Their overall frequency was significantly higher in patients than in controls (odds ratio (OR)=4.47). The most frequent variation was p.Ala91Val (OR=3.92) previously associated with other autoimmune diseases. Clinical analysis showed that PRF1 variations were more frequent in relapsing patients and in patients displaying axonal damage. These data suggest that PRF1 variations may influence CIDP development and course.

    Concomitant central nervous system (CNS) involvement in chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is rare. Although the spinal nerve roots may present MRI abnormalities in CIDP, hitherto, the spinal cord has been investigated in a single study. We retrospectively investigated clinically and with MRI a cohort of patients with definite CIDP diagnosis (EFNS/PNS criteria) for evidence of brain and spinal cord involvement, who were initially admitted in our department during the last 4 years. Among 12 patients with CIDP (men: 8, mean age: 59.3 years, mean disease duration: 3.8 years), nine patients had their MRI scan during a clinical relapse and three during remission. Brain MRI did not document typical multiple sclerosis lesions in any patient. We did not identify any MRI abnormalities in ten patients without clinical evidence of spinal cord involvement. Conversely, MRI disclosed extensive lesions of the thoracic cord in two patients with an overt spinal cord syndrome, whom we describe. This represents the biggest MRI study of CIDP patients who have been investigated for spinal cord involvement. Our data support earlier observations that a minority of CIDP patients may additionally develop CNS involvement of variable degree.

    Distal compound muscle action potential (DCMAP) dispersion, defined as a DCMAP duration > or = 9 ms, and proximal-distal (P-D) CMAP dispersion are considered useful in the electrodiagnosis of chronic inflammatory demyelinating polyneuropathy (CIDP). Distal and P-D CMAP dispersion have not been fully studied in hereditary neuropathies, and it is not known whether these measures distinguish hereditary from acquired demyelination. We compared DCMAP duration and P-D CMAP dispersion in 91 genetically characterized hereditary neuropathies and 33 subjects with CIDP. DCMAP dispersion was more frequent in nerves affected by CIDP (41.5%) than in Charcot-Marie-Tooth disease (CMT)1A (24.4%), CMT1B (7.4%), hereditary neuropathy with liability to pressure palsies (HNPP) (10.5%), or CMTX (9.8%). P-D CMAP dispersion was more frequent in CIDP (27.7% of nerves) than in hereditary neuropathies (16.3%) when applying American Academy of Neurology (AAN) criteria; however, its frequency was similar in CIDP and the hereditary neuropathies using the more restrictive criteria of the American Association of Neuromuscular and Electrodiagnostic Medicine (AANEM). Although dispersion is more common in CIDP than in the hereditary neuropathies, DCMAP and P-D dispersion occur in at least one motor nerve in a significant proportion of hereditary neuropathies, and cannot be used in isolation to distinguish acquired from hereditary demyelination.

    Full Text Available Typical presentation of type A aortic dissection usually encompasses severe acute chest pain, frequently radiating to the upper back, which is seen in more than 80% of the patients, while isolated back or abdominal pain have been repeatedly reported as the first manifestation of the disease as well. Occasionally, dyspnea due to acute aortic regurgitation, syncope, or stroke, secondary to obstruction of major cerebral vessels, have also been described at presentation of type A aortic dissection. Presentation of aortic dissection as a prolonged systemic illness with a number of nonspecific clinical and laboratory findings, such as low-grade fever, fatigue, malaise, weight loss, anemia, elevated acute phase response laboratory parameters, and absence of any of typical clinical features of the dissection syndrome has been only rarely reported. We describe a patient with type A chronic aortic dissection, manifesting as a systemic inflammatory disorder in the absence of acute chest syndrome. The diagnosis was made accidentally by computed tomography, ordered in the course of the regular work up. The patient underwent emergent surgery with resection and grafting of the dissected aorta. Pathological investigation demonstrated intense acute inflammation with neutrophilic infiltration in the vicinity of the intramural hemorrhage and necrosis, as well as granulation tissue with new vessels formation and collagen deposition in the outer media. The possible pathogenic mechanisms of the phenomenon are discussed. [Int J Res Med Sci 2016; 4(5.000: 1768-1771

    Full Text Available The objective of the research is to study the possibilities of ozone- and bacteriophage treatment (OBPT in correction of endotoxicosis and immunological disorders in patients of chronic inflammatory diseases of uterine adnexa (CIDUA. Materials and Methods. There have been examined 100 patients with CIDUA, 50 of them have received OBPT, and 50 — traditional treatment. Some parameters of systemic and tissue immunity have been studied. Results and Discussion. The analysis of dynamics of clinical and immune values against the background of the two methods of treatment has revealed that the response to provocation of inflammatory process complication by administration of saturating ozone concentration (5000 mkg/l and Prodigiosan is the increase of intoxication, CIC, IL-6. Henceforth, the compared methods of treatment have showed significant difference. So, OBPT has caused the normalization of the changed acute-phase values, immunological parameters including local ones. The patients’ follow-up within a year has revealed lower recurrence rate of CIDUA complications after OBPT. It makes it possible to consider the method of ozone- and bacteriophage treatment to be pathogenetically reasonable component of complex treatment of chronic inflammatory diseases of uterine adnexa.

  10. Natural Products as Tools for Defining How Cellular Metabolism Influences Cellular Immune and Inflammatory Function during Chronic Infection

    Full Text Available Chronic viral infections like those caused by hepatitis C virus (HCV and human immunodeficiency virus (HIV cause disease that establishes an ongoing state of chronic inflammation. While there have been tremendous improvements towards curing HCV with directly acting antiviral agents (DAA and keeping HIV viral loads below detection with antiretroviral therapy (ART, there is still a need to control inflammation in these diseases. Recent studies indicate that many natural products like curcumin, resveratrol and silymarin alter cellular metabolism and signal transduction pathways via enzymes such as adenosine monophosphate kinase (AMPK and mechanistic target of rapamycin (mTOR, and these pathways directly influence cellular inflammatory status (such as NF-κB and immune function. Natural products represent a vast toolkit to dissect and define how cellular metabolism controls cellular immune and inflammatory function.

  11. The possibility of evaluation on inflammatory change at respiratory tract in chronic bronchial asthma using 67Ga scintigraphy

    International Nuclear Information System (INIS)

    67Ga scintigraphy was performed in 17 patients with chronic bronchial asthma to grasp the inflammatory change of respiratory tract. On 67Ga scintigraphy, abnormal accumulations were detected on lung fields in 6 cases (35.3%) of 17 cases. In 5 cases of these 6 cases, the defect areas which were pointed out on 81mKr ventilation scintigraphy were matched to the abnormal accumulation areas which were pointed out on 67Ga scintigraphy. In dynamics, the abnormal accumulation areas which were pointed out on 67Ga scintigraphy were matched to the defect areas which had been at all times pointed out on 81mKr ventilation scintigraphy. 67Ga scintigraphy was expected to be one of index to grasp the inflammatory change of respiratory tract in patients with chronic bronchial asthma.

    Full Text Available Abstract Background The surfactant proteins B (SP-B and C (SP-C are important for the stability and function of the alveolar surfactant film. Their involvement and down-regulation in inflammatory processes has recently been proposed, but their level during neutrophilic human airway diseases are not yet known. Methods We used 1D-electrophoresis and Western blotting to determine the concentrations and molecular forms of SP-B and SP-C in bronchoalveolar lavage (BAL fluid of children with different inflammatory airway diseases. 21 children with cystic fibrosis, 15 with chronic bronchitis and 14 with pneumonia were included and compared to 14 healthy control children. Results SP-B was detected in BAL of all 64 patients, whereas SP-C was found in BAL of all but 3 children; those three BAL fluids had more than 80% neutrophils, and in two patients, who were re-lavaged later, SP-C was then present and the neutrophil count was lower. SP-B was mainly present as a dimer, SP-C as a monomer. For both qualitative and quantitative measures of SP-C and SP-B, no significant differences were observed between the four evaluated patient groups. Conclusion Concentration or molecular form of SP-B and SP-C is not altered in BAL of children with different acute and chronic inflammatory lung diseases. We conclude that there is no down-regulation of SP-B and SP-C at the protein level in inflammatory processes of neutrophilic airway disease.

    AIMS: Chagas disease, caused by the protozoan Trypanosoma cruzi is endemic in Latin America, and may lead to a life-threatening inflammatory dilated, chronic Chagas cardiomyopathy (CCC). One third of T. cruzi-infected individuals progress to CCC while the others remain asymptomatic (ASY). A possible genetic component to disease progression was suggested by familial aggregation of cases and the association of markers of innate and adaptive immunity genes with CCC development. Since mutations i...

    Background Chronic obstructive pulmonary disease (COPD) is a progressive disease associated with a cellular inflammatory response mostly concerned with cigarette smoking.Chemokine receptors CCR1/5 play an important role in the inflammatory cells recruitment in the lung of COPD patients.The aim of this study was to determine the impact of cigarette smoking on the expression of CCR1/5 on inflammatory cells in induced sputum,and the relationship between the receptors expression and COPD severity.Methods Differential cells in induced sputum were counted and the optical densities of CCR1 and CCR5 on inflammatory cells in induced sputum from COPD patients (n=29),healthy smokers (n=11),and nonsmokers (n=6) were measured using immunocytochemistry.Concentrations of CCL3,the ligand of CCR1/5,in supernatant of induced sputum were detected by enzyme-linked immunosorbent assay.Results The expressions of CCR1 and CCR5 on inflammatory cells in healthy smokers were significantly higher than those in nonsmokers,and the expression of CCR1 in patients with COPD was significantly increased when compared with nonsmokers but not healthy smokers.The expressions of CCR1 and CCR5 on inflammatory cells in severe and very severe COPD patients were higher compared with mild and moderate COPD patients.CCL3 level was positively correlated with the total cell counts in induced sputum and smoking history,and negatively correlated with percentage of predicted FEV1.Conclusions Cigarette smoking could increase the expression of CCR1 on the inflammatory cells.Both CCR1 and CCR5 expressions on the inflammatory cells in induced sputum could be associated with COPD severity.

    Full Text Available BACKGROUND: Hnf4alpha, an epithelial specific transcriptional regulator, is decreased in inflammatory bowel disease and protects against chemically-induced colitis in mice. However, the precise role of this factor in maintaining normal inflammatory homeostasis of the intestine remains unclear. The aim of this study was to evaluate the sole role of epithelial Hnf4alpha in the maintenance of gut inflammatory homeostasis in mice. METHODOLOGY/PRINCIPAL FINDINGS: We show here that specific epithelial deletion of Hnf4alpha in mice causes spontaneous chronic intestinal inflammation leading to focal areas of crypt dropout, increased cytokines and chemokines secretion, immune cell infiltrates and crypt hyperplasia. A gene profiling analysis in diseased Hnf4alpha null colon confirms profound genetic changes in cell death and proliferative behaviour related to cancer. Among the genes involved in the immune protection through epithelial barrier function, we identify the ion transporter claudin-15 to be down-modulated early in the colon of Hnf4alpha mutants. This coincides with a significant decrease of mucosal ion transport but not of barrier permeability in young animals prior to the manifestation of the disease. We confirm that claudin-15 is a direct Hnf4alpha gene target in the intestinal epithelial context and is down-modulated in mouse experimental colitis and inflammatory bowel disease. CONCLUSION: Our results highlight the critical role of Hnf4alpha to maintain intestinal inflammatory homeostasis during mouse adult life and uncover a novel function for Hnf4alpha in the regulation of claudin-15 expression. This establishes Hnf4alpha as a mediator of ion epithelial transport, an important process for the maintenance of gut inflammatory homeostasis.

    Full Text Available Background. The serum levels of neopterin, a marker associated with cell-mediated immunity are elevated in chronic kidney disease (CKD. We evaluated serum neopterin levels and investigated its association with markers of inflammation in a cross-section of CKD subjects without known cardiovascular disease. Methods. Serum neopterin levels were measured in 118 patients with stage 3–5 CKD and 41 healthy subjects with normal kidney function (HC. Patients with known cardiovascular disease were excluded. We also estimated highly sensitive CRP (hsCRP and interluekin-6 (IL-6, tumor necrosis factor-α (TNF-α and interferon-γ (IFN-γ in the CKD subjects. All assays were done using commercially available ELISA kits. The correlation between neopterin and markers of inflammation were investigated. Results. Of the CKD population, 82 were in stage 5 (60 stage 5 D, 24 in stage 4, and 12 in stage 3. The mean age was 51.04±1.3 years and 66% were males. The commonest cause of CKD was diabetes (36%. Serum neopterin levels were 5-fold higher in CKD patients as compared to HC (74.8±3.6 versus 15.0±2.8 nmol/L, P<0.0001. There was a graded increase of serum neopterin from stages 3 to 4 and 5. CKD 5 D patients exhibited significantly higher levels compared to nondialysis stage 5 patients (P<0.0001. An inverse correlation was noted between serum neopterin and eGFR (r=−0.359, P<0.0001. Serum neopterin correlated with hsCRP (r=0.285, P=0.002, IL-6 (r=0.212, P=0.034, and IFN-γ (r=0.32, P=0.001 but not with TNF-α. Conclusion. Serum neopterin level is elevated and correlates with the severity of CKD. The elevation correlates with elevation of most, but not all, inflammatory markers. Its role in future development of cardiovascular disease and modulation with anti-inflammatory therapies needs further studies.

    Full Text Available Pharmacological treatment of inflammatory pain is usually done by administration of non-steroidal anti-inflammatory drugs (NSAIDs. These drugs present high efficacy, although side effects are common, especially gastrointestinal lesions. One of the pharmacological strategies to minimize such effects is the combination of drugs and natural products with synergistic analgesic effect. The monoterpene terpinolene (TPL is a chemical constituent of essential oils present in many plant species, which have pharmacological activities, such as analgesic and anti-inflammatory. The association of ineffective doses of TPL and diclofenac (DCF (3.125 and 1.25 mg/kg po, respectively presented antinociceptive and anti-inflammatory effects in the acute (0, 1, 2, 3, 4, 5 and 6 h, after treatment and chronic (10 days inflammatory hyperalgesia induced by Freund's complete adjuvant (CFA in the right hind paw of female Wistar rats (170-230 g, n=6-8. The mechanical hyperalgesia was assessed by the Randall Selitto paw pressure test, which determines the paw withdrawal thresholds. The development of edema was quantified by measuring the volume of the hind paw by plethismography. The TPL/DCF association reduced neutrophils, macrophages and lymphocytes in the histological analysis of the paw, following a standard staining protocol with hematoxylin and eosin and the counts were performed with the aid of optical microscopy after chronic oral administration of these drugs. Moreover, the TPL/DCF association did not induce macroscopic gastric lesions. A possible mechanism of action of the analgesic effect is the involvement of 5-HT2A serotonin receptors, because ketanserin completely reversed the antinociceptive effect of the TPL/DCF association. These results suggest that the TPL/DCF association had a synergistic anti-inflammatory and analgesic effect without causing apparent gastric injury, and that the serotonergic system may be involved in the antinociceptive effect of this

    Zinc status was studied in 30 patients with chronic inflammatory bowel disease (CIBD) as well as in 17 normal children, 13 primordial short stature, and 17 anorexia nervosa patients. Basal serum and urinary excretion levels of zinc were measured in all patients. In addition, a zinc loading test was performed in 16 CIBD patients, 21 normal and/or short stature children, and nine patients with anorexia nervosa. Eleven of 30 patients with CIBD had serum zinc values less than 0.7 microgram/ml, whereas none of the other patients had hypozincemia. In addition, the mean urinary zinc excretion of CIBD patients was significantly lower than that of patients with primordial short stature and with anorexia nervosa. An altered response to oral zinc load was the most frequent abnormality in CIBD patients. Those with moderate and severe clinical disease activity had a decreased serum rise of zinc after the oral load of this ion. Urinary excretion of zinc after oral load was also marked by deficiency in all CIBD patients. The abnormalities of zinc metabolism were more frequent among the CIBD patients with growth abnormalities, although they were also found in patients who had normal growth. Among the 14 patients with CIBD and growth abnormalities, seven were hypozincemic and four hypozincuric. Hypozincemia was only found in four patients who had normal height; however, the growth velocity was not known. The zinc tolerance test revealed abnormalities in four of five CIBD patients with short stature and in two of three patients with slow growth. On the other hand, similar alterations in zinc tolerance tests were seen in three of seven CIBD patients with normal height and growth. PMID:7435430

    Full Text Available Abstract Background A progressive development of hepatic steatosis with an increase in the lipid hepatocyte content and the formation of megamitochondria have been demonstrated in rats with prehepatic portal hypertension. The aim of this study is to verify the existence of liver and serum lipid metabolism impairments in rats with long-term (2 years portal hypertension. Methods Male Wistar rats: Control (n = 10 and with prehepatic portal hypertension by triple partial portal vein ligation (n = 9 were used. Liver content of Triglycerides (TG, phospholipids (PL and cholesterol and serum cholesterol, lipoproteins (HDL and LDL, TG, glucose and Lipid Binding Protein (LBP were assayed with specific colorimetric commercial kits. Serum levels of insulin and somatostatin were assayed by RIA. Results The liver content of TG (6.30 ± 1.95 vs. 4.17 ± 0.59 μg/ml; p vs. 1.10 ± 0.13 μg/ml; p vs. 114.78 ± 37.72 mg/dl, TG (153.41 ± 80.39 vs. 324.39 ± 134.9 mg/dl; p vs. 55.15 ± 17.47 mg/dl; p vs. 1.59 +0.37 mg/dl decreased, whereas LDL (37.83 ± 15.39 vs. 16.77 ± 6.81 mg/dl; p vs. 60.27 ± 42.96 ng/ml; p Conclusion Portal hypertension in the rat presents changes in the lipid and carbohydrate metabolisms similar to those produced in chronic inflammatory conditions and sepsis in humans. These underlying alterations could be involved in the development of hepatic steatosis and, therefore, in those described in the metabolic syndrome in humans.

    Evidence-based therapies for chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) consist of corticosteroids, intravenous immunglobulins (IVIg), and plasma exchange. Steroids represent the oldest treatment used historically. In countries where readily available and affordable, IVIg tends to be favored as first-line treatment. The reason for this preference, despite substantially higher costs, is the perception that IVIg is more efficacious and safer than corticosteroids. However, the unselected use of IVIg as a first-line treatment option in all cases of CIDP raises issues of cost-effectiveness in the long-term. Furthermore, serious although rare, particularly thromboembolic side effects may result from their use. Recent data from randomized trials suggest pulsed corticosteroids to have a higher potential in achieving therapy-free remission or longer remission-free periods compared with IVIg, as well as relatively low rates of serious side effects when given as pulsed intravenous infusions during short periods of time. These specific advantages suggest that pulsed steroids could in many cases be used, as the first, rather than second choice of treatment when initiating immunomodulation in CIDP, primarily in hopes of achieving a remission after the short-term use. This article reviews the evidence base for the use of corticosteroids in its various forms in CIDP and factors that may influence clinicians' choice between IVIg and pulsed steroid treatment. The issue of efficacy, relapse rate and time, and side effect profile are analyzed, and some aspects from the authors' experience are discussed in relation to the possibility of using the steroid option as first-line therapy in a large proportion of patients with CIDP.

    Chronic inflammatory demyelinating polyneuropathy (CIDP) is an idiopathic immune mediated neuropathy causing demyelination and conduction block thought to occur as the result of an aberrant autoimmune response resulting in peripheral nerve inflammation mediated by T cells and humoral factors. Diagnosis commonly prompts initial treatment with steroids or intravenous immunoglobulin (IVIG) on which 5-35% subsequently become dependent to maintain function. Despite a number of small scale trials, the role for alternative long-term immunosuppression remains unclear. Alemtuzumab is a humanised monoclonal antibody targeting the CD52 antigen present on the surface of lymphocytes and monocytes. A single intravenous infusion results in rapid and profound lymphopoenia lasting >12 months. We report its use and clinical outcome in a small series of patients with severe IVIG-dependent CIDP. Seven patients (4 Males; 3 Females) who had failed to respond to conventional immunosuppression were treated in 5 centres receiving 9 courses of alemtuzumab (dose range 60-150 mg). Following treatment, mean monthly IVIG use fell 26% from 202 to 149 g and IVIG administration frequency from 22 to 136 days. Two patients had prolonged remission, two patients had a partial response and no clear benefit was observed in the remaining three patients (2 Males, 1 Females). Responding patients had a younger age at onset (19.5 years) and shorter disease duration than non-responders. Three patients developed autoimmune disease following treatment. Alemtuzumab may offer an alternative treatment for a subset of early onset IVIG dependent CIDP patients failing conventional immunosuppressive agents, but concerns about toxicity may limit its use.

    Full Text Available Background : According to American Academy of Neurology (AAN criteria, demonstration of demyelination in the sural nerve by teased fiber or ultrastructure is considered mandatory for diagnosis of chronic inflammatory demyelinating polyneuropathies (CIDP. In resource-restricted settings where these techniques are not freely available, it is useful to determine the utility of ′supportive′ pathologic criteria (subperineurial edema, inflammation, onion bulb formation, and demyelination proposed by AAN for diagnosis of CIDP. Settings and Design : Tertiary care hospital, retrospective study. Patients and Methods : Forty-six patients with idiopathic CIDP (32 with progressive course and 14 with relapsing-remitting course satisfying AAN clinical and electrophysiologic criteria evaluated between January 1991 and August 2004 were reviewed. Frequency of specific pathological alterations such as demyelination, inflammation, onion bulb formation, and axonal changes in sural nerve biopsies was evaluated. Statistical Analysis : SPSS statistical package was used to calculate mean, range, and standard deviation. Student′s t test, chi-square test, and ANOVA were used for determining statistical significance. Results and Conclusion : Reduction in myelinated fiber density was most frequent (93.5%, followed by demyelination (82.8%, inflammation (58.7%, and onion bulb formation (28.3%. Endoneurial inflammation was frequent in the relapsing-remitting form and epineurial inflammation and axonal changes in those with progressive course. Greater disability at presentation, poor response to immunomodulation, and lower CSF protein levels was seen in those with axonal pathology. Pathological abnormalities were demonstrable in all (100%, whereas electrophysiological abnormalities were detected in 90.8%, suggesting that supportive histologic AAN criteria are helpful in diagnosis of CIDP.

    Full Text Available Background: The clinical presentation, neurophysiological findings, and outcome may vary between primary and secondary chronic inflammatory demyelinating polyradiculopathy (CIDP. Objective: To compare clinical and electrodiagnostic features of primary and secondary CIDP. Setting: Tertiary care teaching referral hospital. Materials and Methods: The CIDP patients who were diagnosed as per European Federation of Neurological Societies/Peripheral Nerve Society criteria were included and subjected to detailed history and examinations. The clinical disability was graded on a 0-10 scale. Neurophysiology included motor and sensory nerve conductions and F wave studies of all four limbs. Based on investigations for underlying diseases, the patients were categorized into primary or secondary CIDP. Prednisolone was prescribed in all and azathioprine added in resistant cases. The secondary CIDP group received specific treatment in addition. The outcome was assessed at 3 months, 6 months, and last follow-up. Results: A total of 65 patients aged 17 to 72 years were included and 20 were females. Twenty-five patients had secondary CIDP and include diabetes mellitus (16, POEMS (polyneuropathy, organomegaly, endocrinopathy, M protein, and skin changes (4, monoclonal gammopathy of undetermined significance (2, myeloma (1, lymphoma (1, and malignancy (1. The secondary CIDP patients were older (48.35 vs 41.0 years, had less relapsing remitting (0 vs 6 and more frequent dysautonomia (7 vs 1. The demyelinating features were more marked in primary CIDP group and had better outcome compared with secondary CIDP. Conclusions: Of the total patients with CIDP, 38.5% of patients had secondary CIDP which was associated with progressive course, less demyelinating features, and worse prognosis.

    Our purpose was to clarify the magnetic resonance (MR) imaging characteristics of the brachial and lumbar plexuses in patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) using various kinds of sequences, including diffusion-weighted images (DWI). We evaluated the MR imaging findings for lumbar and/or brachial nerve plexuses in 13 CIDP patients and 11 normal volunteers. The nerve swelling was evaluated in comparison with normal controls by coronal short tau inversion recovery (STIR), and signal abnormalities were evaluated by coronal STIR, T1-weighted images, and DWIs. The degrees of contrast enhancement and apparent diffusion coefficient (ADC) values of the plexus were also assessed. In the patient group, diffuse enlargement and abnormally high signals were detected in 16 out of 24 plexuses (66.7%) on STIR, a slightly high signal was detected in 12 of 24 plexuses (50%) on T1-weighted images, and a high-intensity signal was detected in 10 of 18 plexuses (55.6%) on DWIs with high ADC values. Contrast enhancement of the plexuses was revealed in 6 of 19 plexuses (31.6%) and was mild in all cases. There were statistically significant differences between the ADC values of patients with either swelling or abnormal signals and those of both normal volunteers and patients without neither swelling nor abnormal signals. There were no relationships between MR imaging and any clinical findings. STIR is sufficient to assist clinicians in diagnosing CIDP. T1-weighted images and DWIs seemed useful for speculating about the pathological changes in swollen plexuses in CIDP patients. (orig.)

  16. Curcumin Protects Against the Acute Inflammatory Process in Irradiated Rats

    International Nuclear Information System (INIS)

    Nutraceuticals that provide medical or health benefits, including prevention and treatment of disease may be advantageous in inflammation and exposure to radiation. The aim of this study was to investigate the potential of curcumin to modulate, counteract or prevent the inflammatory response induced in irradiated and non-irradiated rats using the carrageenan air-pouch model as an acute model. Diclofenac was used as a reference standard non-steroidal anti-inflammatory drug (NSAID). Results indicated that exposure of rats to a single dose of gamma-radiation (6 Gy) before induction of inflammation increased production of prostaglandin E2 (PGE2), tumour necrosis factor-alpha (TNF-alpha) and malondialdehyde (MDA) levels in serum. Blood glutathione (GSH) was shown to be reduced in irradiated animals. Curcumin suppressed the elevated levels of TNF-alpha, PGE2 and MDA and was able to restore blood GSH levels. Reduction in liver contents of copper (Cu), zinc (Zn), selenium (Se) and iron (Fe) was recorded after irradiation of animals before induction of inflammation. Curcumin restored the hepatic concentrations of these trace elements. The present results suggest that irradiation of rats caused marked changes in the inflammatory response while curcumin suppressed the inflammatory response in both irradiated and control animals.

    1 The present study was undertaken to characterize the spectrum of arachidonic acid metabolites present in synovial effusions of patients with rheumatoid or psoriatic arthritis, and to compare changes in their concentration following a short-term treatment with 6α-methyl-prednisolone (6-MeP: 4-8 mg/day) or indoprofen (1.2 g/day), a nonsteroidal anti-inflammatory agent with proven synovial prostaglandin inhibitory effect. 2 Measurements of prostaglandin E2 (PGE2), thromboxane (TX) B2, 6-keto-PGF1α and PGF2α were performed by radioimmunoassay techniques in synovial effusions obtained from 23 patients, and validated by thin-layer chromatographic analysis of the extracted immunoreactivity. 3 PGE2 and TXB2 accounted for more than 60% of the total immunoreactivity in untreated patients. The absence of any constant ratio between the different arachidonic acid metabolites detected in synovial fluid is consistent with a heterogeneous cellular origin of these compounds. 4 Indoprofen treatment was associated with a consistent reduction of synovial prostaglandin and thromboxane concentrations, ranging from 36% in the case of 6-keto-PGF1α to 90% in the case of PGE2. 5 In contrast, 6-MeP caused opposite changes on different metabolites originating via the cyclo-oxygenase pathway. Thus, 6-keto-PGF1α concentrations were reduced by 35%, PGF2α concentrations were increased by 30%, while PGE2 and TXB2 were unchanged following 6-MeP. 6 Although the mechanism(s) underlying the failure of 6-MeP to reduce synovial PGE2 and TXB2 levels are uncertain, the results of the present study clearly indicate that therapeutic doses of steroidal and nonsteroidal anti-inflammatory drugs cause quite distinct changes in arachidonic acid metabolism, which might be relevant to their specific therapeutic actions and side-effects.

    Full Text Available Low activity of saliva α-amylase has been stated to be registered in every second child with chronic inflammatory gastric and duodenal diseases at the age of 3—7 years, more frequently against the background of alimentary allergy. The risk factors of forming low activity of α-amylase saliva have been revealed. The data obtained allows recommending a saliva amylolytic activity test as a noninvasive screening of chronic inflammatory gastric and duodenal diseases in preschool children.

    Full Text Available Context: Systemic conditions, especially chronic infections, have a direct impact on the general health and well-being of an individual. Similarly, the long-standing inflammatory changes seen during periodontitis have been associated with the altered diabetic control, preterm, low birth weight infants, and cardiovascular disease. Being a low-grade infection, the signs may not be as severe as seen in other systemic conditions, but they definitely cannot be ignored. Aims: The present study was designed to compare clinical, hematological, and systemic inflammatory markers in patients with chronic periodontitis. Subjects and Methods: A total of 90 chronic periodontitis patients were selected for the present study from the outpatient department of the Department of Periodontology, and the various clinical and hematological parameters were then assessed. Statistical Analysis Used: Z-test was used to compare the probing depth, clinical attachment loss, hematological parameter, and interleukin-6 values between Group A and Group B. Mann-Whitney U-test was used to compare gingival index, plaque index, and bleeding on probing between Group A and Group B. Results: The results of the study were based on the comparison of the clinical, hematological, and systemic inflammatory markers in smokers and nonsmokers with chronic periodontitis and came out to be statistically highly significant. Conclusions: With the resurgence of emphasis on significance of oral diseases related to systemic health, the medical professionals also need to familiarize themselves with the oral cavity and the oral-systemic inter-relationships to treat or reduce the morbidity of the underlying medical condition. Furthermore, the oral health care professionals must reach out to the medical community and the general public to improve patient care through education and communication about the oral health-systemic health link.

    Psoriasis is a common, chronic immune-mediated inflammatory disease. The inflammatory process in psoriasis has systemic effects and may influence the development of psoriatic comorbidities. The systemic action of phototherapy in patients with psoriasis has been so far poorly elucidated. We aimed to investigate the expression of genes encoding selected psoriasis-related cytokines in peripheral blood mononuclear cells (PBMCs) isolated from patients with psoriasis before and after treatment with phototherapy. 17 patients with mild to moderate plaque psoriasis were treated with narrow band-UVB (NB-UVB), 8 patients with moderate to severe plaque psoriasis with bath-psoralen-ultraviolet A therapy (PUVA). PBMCs were isolated by Ficoll gradient density centrifugation. Expression of genes encoding TNF-α, IL-17A, IL-6, IL-1 β, INF-γ, and IL-10 in PBMCs of patients with psoriasis before and after phototherapy was analyzed with quantitative RT-PCR. Treatment with NB-UVB therapy led to a significant decrease in IL-17A, TNF-α, and IL-6 mRNA levels in PBMCs (p=0.003; p=0.042; p=0.019, respectively). Following treatment with bath-PUVA therapy, we observed a significant decrease in TNF-α and IL-6 mRNA levels in PBMCs (p=0.031, p=0.035, respectively). Treatment with phototherapy in patients with psoriasis may affect systemic inflammation by downregulation of the expression of genes encoding proinflammatory cytokines in PBMCs, implicated in the development of psoriasis and psoriatic comorbidities.

    A number of anti-tumor necrosis factor alpha (TNF-α) biologics have been developed in recent years, such as adalimumab, etanercept, and infliximab for the treatment of chronic inflammatory disorders like rheumatoid arthritis (RA), inflammatory bowel disease (IBD), and psoriasis and several other...... not respond to anti-TNF-α treatment and one possible explanation may be the heterogeneity of chronic inflammatory diseases and a dominance of other significant TNF family members. Indeed, polymorphisms in the TNF family member, TL1A gene, is associated with the development of IBD and increased serum...

    Full Text Available Gastroesophageal reflux disease (GERD is defined with clinical symptoms of heart burning and regurgitation. It may be associated with external esophageal symptoms such as chronic cough, asthma, laryngitis, chronic lung disease, sinusitis and pulmonary fibrosis. In the present study, rats with chronic aspiration of gastroduodenal contents were studied for cellular phenotypes and cytokine concentrations in bronchoalveolar lavage and lung tissue. Thirty-six male Albino N-MRI rats were randomly divided into six groups. After anesthesia and tracheal intubation, the animals received either 0.5ml/kg of normal saline (control, gastric juice, pepsin, hydrochloric acid or bile salts by injection into their lungs twice a week for 8 weeks. In sham group nothing was injected. Thereafter, cellular phenotypes and cytokine concentrations of Interleukine (IL-1α, IL-1β, Transforming Growth Factor (TGF-β, Tumor Necrosis Factor (TNF-α, and IL-6 were assessed in bronchoalveolar lavage and lung tissue homogenates. The numbers of epithelial cells, macrophages, neutrophils and lymphocytes in BAL and levels of cytokines IL-1α, IL-6, TNF-α and TGF-β in BAL and lung tissue of test groups were significantly higher than the control group. Aspiration of bile salts caused more cytokine levels and inflammatory cells compared to other reflux components. It can be concluded that GERD with increased cytokines and inflammatory cells in lung could cause or exacerbate asthma and pulmonary fibrosis.

    Psoriasis and atopic dermatitis are chronic and relapsing inflammatory diseases of the skin affecting a large number of patients worldwide. Psoriasis is characterized by a T helper type 1 and/or T helper type 17 immunological response, whereas acute atopic dermatitis lesions exhibit T helper type 2-dominant inflammation. Current single gene and signaling pathways-based models of inflammatory skin diseases are incomplete. Previous work allowed us to model psoriasis in skin-humanized mice through proper combinations of inflammatory cell components and disruption of barrier function. Herein, we describe and characterize an animal model for atopic dermatitis using similar bioengineered-based approaches, by intradermal injection of human T helper type 2 lymphocytes in regenerated human skin after partial removal of stratum corneum. In this work, we have extensively compared this model with the previous and an improved version of the psoriasis model, in which T helper type 1 and/or T helper type 17 lymphocytes replace exogenous cytokines. Comparative expression analyses revealed marked differences in specific epidermal proliferation and differentiation markers and immune-related molecules, including antimicrobial peptides. Likewise, the composition of the dermal inflammatory infiltrate presented important differences. The availability of accurate and reliable animal models for these diseases will contribute to the understanding of the pathogenesis and provide valuable tools for drug development and testing.

  5. High-resolution CT in the differential diagnosis of consolidative lung processes. Pt. 2. Chronic processes

    International Nuclear Information System (INIS)

    Consolidations are characterized on CT by the presence of one or more air-space opacities with little or no volume loss. Because HRCT findings overlap among various entities, it may be sometimes to be impossible to make a definite diagnosis with imaging criteria alone. If the symptoms are chronic (weeks to months) the differential diagnosis may include alveolar proteinosis, bronchioloalveolar carcinoma, lymphoma as well as inflammatory diseases. This review describes the most common types of lung diseases associated with chronic appearance of consolidation and discuss the differential diagnosis. (orig.)

    Full Text Available Two of the crucial aspects of human immunodeficiency virus (HIV infection are (i viral persistence in reservoirs (precluding viral eradication and (ii chronic inflammation (directly associated with all-cause morbidities in antiretroviral therapy (ART-controlled HIV-infected patients. The objective of the present study was to assess the potential involvement of adipose tissue in these two aspects. Adipose tissue is composed of adipocytes and the stromal vascular fraction (SVF; the latter comprises immune cells such as CD4+ T cells and macrophages (both of which are important target cells for HIV. The inflammatory potential of adipose tissue has been extensively described in the context of obesity. During HIV infection, the inflammatory profile of adipose tissue has been revealed by the occurrence of lipodystrophies (primarily related to ART. Data on the impact of HIV on the SVF (especially in individuals not receiving ART are scarce. We first analyzed the impact of simian immunodeficiency virus (SIV infection on abdominal subcutaneous and visceral adipose tissues in SIVmac251 infected macaques and found that both adipocytes and adipose tissue immune cells were affected. The adipocyte density was elevated, and adipose tissue immune cells presented enhanced immune activation and/or inflammatory profiles. We detected cell-associated SIV DNA and RNA in the SVF and in sorted CD4+ T cells and macrophages from adipose tissue. We demonstrated that SVF cells (including CD4+ T cells are infected in ART-controlled HIV-infected patients. Importantly, the production of HIV RNA was detected by in situ hybridization, and after the in vitro reactivation of sorted CD4+ T cells from adipose tissue. We thus identified adipose tissue as a crucial cofactor in both viral persistence and chronic immune activation/inflammation during HIV infection. These observations open up new therapeutic strategies for limiting the size of the viral reservoir and decreasing low

    Full Text Available Background. Chronic pain is associated with increased morbidity and mortality, predominated by cardiovascular disease and cancer. Investigating related risk factor measures may elucidate the biological burden of chronic pain. Objectives. We hypothesized that chronic pain severity would be positively associated with the risk factor composite. Methods. Data from 12,982 participants in the 6th Tromsø study were analyzed. Questionnaires included demographics, health behaviors, medical comorbidities, and chronic pain symptoms. The risk factor composite was comprised of body mass index, fibrinogen, C-reactive protein, and triglycerides. Chronic pain severity was characterized by frequency, intensity, time/duration, and total number of pain sites. Results. Individuals with chronic pain had a greater risk factor composite than individuals without chronic pain controlling for covariates and after excluding inflammation-related health conditions (p<0.001. A significant “dose-response” relationship was demonstrated with pain severity (p<0.001. In individuals with chronic pain, the risk factor composite varied by health behavior, exercise, lower levels and smoking, and higher levels. Discussion. The risk factor composite was higher in individuals with chronic pain, greater with increasing pain severity, and influenced by health behaviors. Conclusions. Identification of a biological composite sensitive to pain severity and adaptive/maladaptive behaviors would have significant clinical and research utility.

    Full Text Available Inflammatory Bowel Disease (IBD is a group of chronic and relapsing inflammatory disorders of the gastrointestinal system. In these cases, findings are detected in extraintestinal systems also. There is a tendency for thrombotic events in IBD, as in the other inflammatory processes. The pathogenesis of this thrombotic tendency is multidimensional, including lack of natural anticoagulants, prothrombotic media induced via the inflammatory process, long-term sedentary life style, steroid use, surgery, and catheter placement. The aim of this review was to highlight the positive relationship between IBD and thrombotic events, and the proper treatment of at-risk patients.

    Angiostatin, a proteolytic fragment of plasminogen, is a potent anti-angiogenic factor recently shown also to have an inhibitory effect on leukocyte recruitment and macrophage migration. Because both angiogenesis and inflammation play key roles in the progression of chronic kidney disease, we evaluated the effect of angiostatin treatment in the rat remnant kidney model. Rats were pretreated for 4 wk with recombinant adeno-associated viruses expressing either angiostatin or green fluorescence protein. Chronic renal disease was then induced by a subtotal nephrectomy, and rats were killed 8 wk later for analysis. Angiostatin treatment was associated with significantly less proteinuria but no alterations in serum creatinine, creatinine clearance, and blood urea nitrogen levels. Treatment with angiostatin reduced renal peritubular capillary number and decreased urinary nitric oxide levels. Despite reducing capillary density, angiostatin diminished interstitial fibrosis in association with reduced macrophage and T-cell infiltration and renal monocyte chemoattractant protein-1 mRNA levels. In conclusion, angiostatin overexpression was associated with attenuated renal disease progression in a model of chronic kidney injury, likely because of its anti-inflammatory actions. However, its anti-angiogenic actions suggest countering effects that could partially offset its benefit in chronic kidney diseases. PMID:18971211

    Cushing syndrome (CS) is the classic condition of cortisol dysregulation, and cortisol dysregulation is the prototypic finding in Major Depressive Disorder (MDD). We hypothesized that subjects with active CS would show dysfunction in frontal and limbic structures relevant to affective networks, and also manifest poorer facial affect identification accuracy, a finding reported in MDD.Twenty-one patients with confirmed CS (20 ACTH-dependent and 1 ACTH-independent) were compared to 21 healthy controlsubjects. Identification of affective facial expressions (Facial Emotion Perception Test) was conducted in a 3 Tesla GE fMRI scanner using BOLD fMRI signal. The impact of disease (illness duration, current hormone elevation and degree of disruption of circadian rhythm), performance, and comorbid conditions secondary to hypercortisolemia were evaluated.CS patients made more errors in categorizing facial expressions and had less activation in left anterior superior temporal gyrus, a region important in emotion processing. CS patients showed higher activation in frontal, medial, and subcortical regions relative to controls. Two regions of elevated activation in CS, left middle frontal and lateral posterior/pulvinar areas, were positively correlated with accuracy in emotion identification in the CS group, reflecting compensatory recruitment. In addition, within the CSgroup, greater activation in left dorsal anterior cingulatewas related to greater severity of hormone dysregulation. In conclusion, cortisol dysregulation in CS patients is associated with problems in accuracy of affective discrimination and altered activation of brain structures relevant to emotion perception, processing and regulation, similar to the performance decrements and brain regions shown to be dysfunctional in MDD.

    Benign prostatic hyperplasia (BPH) is a common chronic non-malignant condition whose prevalence substantially increases with age. Immune cell infiltration and pro-inflammatory mediators have been implicated in the pathogenesis. Here, we characterized 21 extracellular markers on prostate-infiltrating lymphocytes (PILs) and analyzed expression of 26 soluble proteins in prostate tissue obtained from BPH patients (n = 31). These data were correlated with clinical parameters and compared with peripheral blood mononuclear cells (PBMCs) (n = 10). Increased frequencies of T cells expressing co-inhibitory receptors LAG-3, PD-1, TIM-3 or CTLA-4, and co-stimulatory receptors CD28, OX40 or 4-1BB were observed in BPH tissue compared to PBMCs. These findings are consistent with chronic activation and possible functional exhaustion of PILs that may be further augmented by several identified pro-inflammatory factors, such as IL-8 and MCP-1, promoting inflammation and chemotaxis of immune cells to the prostate. Prostate size and plasma prostate-specific antigen levels positively correlated with IL-8 and MCP-1 concentrations, and frequencies of T cells expressing CTLA-4 and TIM-3. It remains to be established whether the link between inflammation and BPH progression supported by our findings reflects a progressive failure of the immune system leading to decreased immune surveillance and development of prostate cancer.

    Temporomandibular disorders (TMD) are commonly found in the population and usually involve inflammatory processes. Previous studies have shown positive effects of LED (Light emitting diodes) phototherapies on TMD but its action and mechanism in the inflammatory infiltrate of the temporomandibular joint are still poorly understood. The aim of this study was to assess through histological analysis the effectiveness LED (10 J/cm2, λ850 nm, 100 mW, CW) on the inflammation of the temporomandibular joint of rats induced by carrageenan. Thirty animals were divided in two groups with five animals per subgroup according to the experimental times of two, three and seven days: Inflammation and Inflammation + LED phototherapy. The first irradiation was performed 24 h after induction with an interval of 48 h between sessions. After animal death, specimens were processed and stained with HE and Picrosirius. Then the samples were examined histologically. Data were statistically analyzed. The inflammation group showed mild to moderate chronic inflammatory infiltrate among the bone trabecules of the condyle. Over the time-course of the study in the LED group the condyle showed aspects of normality and absent inflammation in some specimens. In all the time-points, no statistically significant differences were found for collagen deposition in the in the condyle and disc when LED was compared to Inflammation group. LED treated groups also demonstrated a smaller number of the layers of the synovial membrane when compared to the non-irradiated groups. It was concluded that, in general, LED phototherapy resulted in a reduction of inflammatory infiltrate in the temporomandibular joint of rat.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an immune-mediated demyelinating disease of the peripheral nervous system. Th17 and Th1 cells contribute to the pathogenesis of most autoimmune diseases, but little is known about their distribution and reciprocal relationship in CIDP. In this study, we analyzed the distribution of Th17, Th1, and Th17/Th1 cells in the peripheral blood and cerebrospinal fluid (CSF). The results showed that the frequency of Th17 cells was significantly higher in the peripheral blood mononuclear cell (PBMCs) and CSF of active CIDP in comparison with remitting CIDP or to other non-inflammatory neurological diseases (ONDs), accompanied by similar findings for Th17/Th1 cells. Both active and remitting CIDP have higher percentage of Th1 cells in the CSF than OND. CSF protein levels positively correlated with the frequencies of Th17 cells either in the PBMCs or CSF of active CIDP, while there was no significant correlation with Th1 cells. In line with these observations, the levels of interleukin-17 (IL-17) in plasma and transcript factors retinoic acid receptor-related orphan receptor (ROR)γt expressed by PBMCs were significantly higher in the active CIDP than remitting CIDP or OND. In summary, our preliminary findings suggest that elevated numbers of inflammatory T cells, especially for Th17 cells, might be an important determinant in the evolution of CIDP.

    PURPOSE: To evaluate pulmonary pathologies in Wegener granulomatosis with sequential computed tomography (CT) in order to differentiate active inflammatory lesions from chronic fibrotic lesions. MATERIAL AND METHODS: Serial CT findings in 38 patients with Wegener granulomatosis were retrospectively analyzed (mean follow-up period, 21 months). The presence, extension, and distribution of the following findings were evaluated with CT: parenchymal nodules, masses, ground-glass attenuation, airspace consolidation, bronchial wall-thickening, bronchiectasis, linear areas of attenuation, pleural irregularities, pleural effusions, hilar and mediastinal lymphadenopathy. RESULTS: Observed in 92% of patients, nodules were the most common CT pathology. Areas of ground-glass attenuation, consolidation, masses of linear attenuation, and tracheal/bronchial wall-thickening were detected in 24%, 26%, 32%, 39%, and 68% of patients. At follow-up, the clearance of lesions was most consistent for areas of ground-glass attenuation (89%), masses (87%), and cavitated nodules (85%). In the follow-up scan, 58% of all nodules, 47% of pulmonary consolidations, and 66% of bronchial wall-thickening were completely resolved. Areas of bronchiectasis and septal/non-septal lines remained stable in 70% and 71% of patients. CONCLUSION: The majority of the lesions decreased or resolved completely with or without areas of linear attenuation. Ground-glass attenuation, cavitated nodules and masses appear to represent active inflammatory lesions. In most probability, areas of bronchiectasis and septal/non-septal lines more often represent chronic fibrotic changes rather than active inflammatory changes. In combination with clinical evaluation and bronchoscopy, CT assists in the assessment of disease activity.

    In order to compare the effect of dexamethasone and bergenin on chronic bronchitis and to reveal their anti-inflammatory mechanisms, (1)H NMR-based metabolomics was performed to explore the potential biomarkers of the disease and study the therapeutic mechanisms of the drugs. In this study, 40 Sprague-Dawley male rats were randomly divided into 4 groups, namely control, model, dexamethasone and bergenin groups, with 10 rats in each group. Except for the control group, rats from the other three groups were exposed to tobacco smoke for 1 h d(-1) for 28 days. During the modeling, dexamethasone (0.2 mg kg(-1)) and bergenin (87 mg kg(-1)) were administered orally to dexamethasone or bergenin rats 3 h after exposure every day. On the other hand, control and model rats were intragastrically administered water. According to the results of morphometric analysis of the airway epithelium and the count of white blood cells in the bronchoalveolar lavage fluid (BALF), dexamethasone and bergenin could suppress the infiltration of inflammatory cells, inhibit the secretion of mucus, and reduce white blood cells in BALF. Serum samples from the rats' orbits were collected every week. The metabolic profiles of sera were analyzed by multivariate statistical analyses, including PCA, PLS-DA and OPLS-DA models, and 18 metabolites were identified. The dynamic fluctuations of these biomarkers in sera from different groups were detected. The results suggested that the anti-inflammatory mechanism of dexamethasone may be associated with BCAA metabolism and glycolysis while bergenin could change BCAA metabolism, glycine, serine and threonine metabolism, and glycolysis to treat chronic bronchitis.

    Chronic stress as well as chronic treatment with glucocorticoids (GCs) primes the neuroinflammatory response to a subsequent pro-inflammatory challenge. However, it remains unclear whether chronic GCs sensitize the response of key CNS immune substrates (i.e. microglia) to pro-inflammatory stimuli. In the present set of studies, male Sprague-Dawley rats underwent sham surgery or were adrenalectomized and then treated with varying concentrations of corticosterone (CORT; 0, 25, 50, and 75 μg/ml) administered in their drinking water. After 10 days of CORT exposure, whole hippocampus was collected and expression of glial activation markers measured or hippocampal microglia were isolated and challenged with LPS to probe for CORT-induced sensitization of pro-inflammatory responses. Chronic CORT exposure increased the gene expression of NLRP3, Iba-1, MHCII, and NF-κBIα in a concentration dependent manner. Chronic CORT (75 μg/ml) exposure potentiated the microglial proinflammatory response (TNFα, IL-1β, IL-6 and NLRP3) to LPS compared to the microglial response of sham surgery animals treated with vehicle. The present set of results demonstrate that chronic exposure to GCs primes microglia to pro-inflammatory stimuli and add to a growing body of evidence suggesting that a permissive function of GCs is that of an endogenous danger signal or alarmin.

    Telomeres are specialized nucleoprotein structures located at the end of linear chromosomes and telomerase is the enzyme responsible for telomere elongation. Telomerase activity is a key component of many cancer cells responsible for rapid cell division but it has also been found by many laboratories around the world that telomere/telomerase biology is dysfunctional in many other chronic conditions as well. These conditions are characterized by chronic inflammation, a situation mostly overlooked by physicians regarding patient treatment. Among others, these conditions include diabetes, renal failure, chronic obstructive pulmonary disease, etc. Since researchers have in many cases identified the association between telomerase and inflammation but there are still many missing links regarding this correlation, the latest findings about this phenomenon will be discussed by reviewing the literature.

    The authors present the case of a 65-year-old woman who was admitted for paraparesis and paresthesias in the inferior limbs. The neurological examination revealed the difficulty in extension of the right foot and of the right toe, accompanied by paresthesias located in the anterolateral area of the right leg, dorsum and plantar area of the foot, the reduction of the right knee jerk, and of the ankle tendon jerk both sides. The vertebro-spinal MRI showed lumbar canal stenosis with L4 intraforaminal compression on the right, and L2-L3 on the left. CSF examination revealed mild increase in protein concentration. The morphological picture of the sural nerve biopsy was compatible with a chronic inflammatory neuropathy and severe muscular lesions of neurogenic origin were observed on right gastrocnemius muscle biopsy. The diagnosis of chronic inflammatory demyelinating polyneuropathy (CIDP) was established. Solu-medrol (0.5 g/d)-5 days, then medrol (prednisolone) was done, followed by improving of the symptomatology. For the relapse of the disease intravenous immunoglobulins (IVIG)-0.4 g/kg/d-5 days was the elective treatment. Six months later she presented a new relapse. IVIG were administered with the remission of the sensitive symptoms. A chronic treatment with medrol was recommended. The diagnosis of L4 disc herniation was obvious in the studied case, but the electroneurographic examination brought extra data for the associated diagnosis of CIDP whose onset was asymmetrical and initially paucisymptomatic. Neither the electroneurographic examination nor the CSF examination were total relevant for CIDP, imposing the sural nerve biopsy. The diagnosis of CIDP involves a team-work composed of neurologist, electroneurophysiologist and neuropathologist. PMID:23610977

    IL-35 downregulates Th17 cell development and suppresses certain types of autoimmune inflammation such as collagen-induced arthritis and experimental autoimmune uveitis. Psoriasis is thought to be initiated by abnormal interactions between cutaneous keratinocytes and systemic immune cells. However, the role of IL-35 in psoriasis remains unclear. In this study, we assessed IL-35 in three well-known psoriasis models: a human keratinocyte cell line (HaCaT), a keratin 14 (K14)-vascular endothelial growth factor A (VEGF-A)-transgenic (Tg) mouse model, and an imiquimod-induced psoriasis mouse model. First, we found that IL-35 suppressed the expression of IL-6, CXCL8, and S100A7, which are highly upregulated by a mixture of five proinflammatory cytokines in HaCaT. Second, a plasmid coding for the human IL-35 sequence coated with cationic liposomes showed potent immunosuppressive effects on K14-VEGF-A-Tg and imiquimod-induced psoriasis mouse models. In the K14-VEGF-A-Tg model, our results showed that several types of proinflammatory cytokines were significantly reduced, whereas IL-10 was remarkably induced by IL-35. Compared with pcDNA3.1, there was a small number of CD4(+)IL-17(+) T cells and a large number of CD4(+)IL-10(+) and CD4(+)CD25(+)Foxp3(+) T cells in the IL-35 group. Most importantly, we found that IL-35 decreased the total number of macrophages and ratio of M1/M2 macrophages, which has not been reported previously. In addition, compared with dexamethasone, IL-35 showed long-term therapeutic efficacy. In summary, our results strongly indicate that IL-35 plays a potent immunosuppressive role in psoriasis. Thus, IL-35 has potential for development as a new therapeutic strategy for patients with chronic psoriasis and other cutaneous inflammatory diseases.

    Mental health disorders(MHD) in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) have been widely studied. However, the underlying role of inflammatory cytokines and their associated signaling pathways have not been investigated. Here, we report the potential role of cytokines and associated signaling pathways in CP/CPPS patients with MHD and in a CP/CPPS animal model. CP/CPPS patients (n = 810) and control subjects (n = 992) were enrolled in this case-control multicenter study, and serum cytokine levels were measured. Male Sprague-Dawley rats received multiple intracutaneous injections of an immuno-agent along with a pertussis-diphtheria-tetanus triple vaccine for autoimmune CP/CPPS development. The results revealed that, in CP/CPPS patients with significant MHD, elevated IL-1α, IL-1β, IL-4, IL-13, and TNF-α serum levels were observed. The above five cytokines in CP/CPPS rats were significantly elevated in prostate tissue (p MHD. PMID:27334333

    The reasons for development of chronic inflammation are complex and not fully understood. One of the factors affecting the prolongation of inflammation is changes in cell metabolism, occurring at the center of the inflammatory process. In chronic inflammation there is an imbalance between the processes of storage and consumption of energy reserves. Hypoxia that is a consequence of edema results in transition of white blood cells to anaerobic metabolism. Neutrophils, lymphocytes and macrophages produce active oxygen metabolites which on one hand facilitate the elimination of pathogens, and on the other hand, can cause damage to healthy cells located in the inflamed tissue. In this paper, we discuss the importance of disturbed redistribution of energy as one of the main reasons for transformation of the acute inflammatory process into the chronic one.

    Intravenous immunoglobulin (IVIg) is often used as preferred treatment in chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). Several studies highlighted the short-term efficacy of IVIg for CIDP yet many patients need maintenance therapy. Notwithstanding the fact IVIg has been used for over 30 years in CIDP, there is only limited evidence to guide dosage and interval during maintenance treatment. The variation in disease course, lack of biomarkers, and fear of deterioration after stopping IVIg makes long-term treatment challenging. Recent studies suggest a proportion of patients receive unnecessary IVIg maintenance treatment. This review provides an overview of the use of IVIg for CIDP treatment, focusing on evidence for long-term IVIg use.

    2014-06-01

    Guillain-Barré syndrome (GBS) and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) are thought to be autoimmune diseases. There have been many attempts to find a human leukocyte antigen (HLA) association with GBS and CIDP with little success. There have been studies of other plausible genes in GBS and CIDP and the role of these genes in GBS and CIDP and the data from these genetic studies is reviewed. Some of the genes that have been studied are immune related and some others have nervous system effects. The studies are limited by small numbers. Some of the genes show association with disease severity rather than disease susceptibility. The need for more detailed molecular studies of the role of HLA molecules and the need for modern genetic approaches to GBS and CIDP are explained.

    Indium-111 leukocyte scanning and colonoscopy were performed in 19 children and adolescents with chronic inflammatory bowel disease to study the correlation of evaluation between these two diagnostic modalities in comparison to histologic study for colonic disease. Seven patients had ulcerative colitis, 10 had Crohn's disease, and two patients had no specific diagnosis after evaluation. The sensitivity of indium-111 scan was 18%, specificity was 62.5%, and accuracy for diagnosing colonic disease was only 37%. In comparison, sensitivity and specificity for colonoscopy were 100 and 57%, respectively. Furthermore, accuracy with colonoscopy was 84%. The authors data suggest that the usefulness of scans is limited to patients in whom standard diagnostic procedures are contraindicated. In addition, it is essential to confirm the visual diagnostic impression on colonoscopy with histologic study.

    Acute phase proteins (APPs) are a group of circulating plasma proteins which undergo changes quantitatively or qualitatively at the time of inflammation. Many of these APPs are glycosylated, and it has been shown that alterations in glycosylation may occur in inflammatory and malignant conditions. Changes in glycosylation have been studied as potential biomarkers in cancer and also in chronic inflammatory conditions and have been shown to correlate with disease severity in certain conditions. Serine protease inhibitors (serpins), many of which are also APPs, are proteins involved in the control of proteases in numerous pathways. Alpha-1 Antitrypsin (AAT) is the most abundant serpin within the circulation and is an APP which has been shown to increase in response to inflammation. The primary role of AAT is maintaining the protease/antiprotease balance in the lung, but it also possesses important anti-inflammatory and immune-modulating properties. Several glycoforms of AAT exist, and they possess differing properties in regard to plasma half-life and stability. Glycosylation may also be important in determining the immune modulatory properties of AAT. The review will focus on the role and importance of glycosylation in acute phase proteins with particular attention to AAT and its use as a biomarker of disease. The review describes the processes involved in glycosylation, how glycosylation changes in differing disease states, and the alterations that occur to glycans of APPs with disease and inflammation. Finally, the review explores the importance of changes in glycosylation of AAT at times of inflammation and in malignant conditions and how this may impact upon the functions of AAT.

    In industrialized nations and high-income regions of the world, the decline of infectious diseases is paralleled by an increase in allergic, autoimmune and chronic inflammatory diseases (AACID). Changes in lifestyle in westernized societies, which impact individually and collectively on intestinal microbiota, may - at least in part - account for the AACID pandemic. Many disease genes that contribute to AACID encode pattern recognition and signalling molecules in barrier-associated cells. Interactions between gene products and environmental factors depend highly upon the host's state of maturation, the composition of the skin and gut microflora, and exposure to pollutants, antibiotics and nutrients. Inflammatory stress responses, if regulated appropriately, ensure immunity, health and relative longevity; when they are dysregulated, they can no longer be terminated appropriately and thus precipitate AACID. The 99th Dahlem Conference brought together experts of various disciplines (genetics, evolution biology, molecular biology, structural biology, cell biology, immunology, microbiology, nutrition science, epidemiology and clinical medicine) to discuss the multi-faceted relationships between infection, immunity and inflammation in barrier organs and the development of AACID. In Clinical and Experimental Immunology we are presenting a compilation of background papers that formed the basis of discussions. Controversial viewpoints and gaps in current knowledge were examined and new concepts for prevention and treatment of CID were formulated.

    Objective: To study the levels of procalcitonin (PCT) in various inflammatory states seen in an internal medicine department and to evaluate the possible discriminative role of PCT in differentiating bacterial infection from other inflammatory processes. Methods: PCT, C reactive protein (CRP), and white blood cell count (WBC) were measured in patients admitted to the department for fever or biological inflammatory syndrome, or both. The serum of 173 consecutive patients was analysed according to the aetiological diagnosis. The patients were divided into two groups: group I (n=60) with documented bacterial or fungal infection; group II (n=113) with abacterial inflammatory disease. Results: PCT levels were >0.5 ng/ml in 39/60 (65%) patients in group I. In group II, three patients with a viral infection had slightly increased PCT levels (0.7, 0.8, and 1.1 ng/ml) as did two others, one with crystal arthritis and the other with vasculitis (0.7 ng/ml in both cases). All other patients in group II had PCT levels 0.5 ng/ml was taken as the marker of bacterial infection (sensitivity 65%, specificity 96%). PCT values were more discriminative than WBC and CRP in distinguishing a bacterial infection from another inflammatory process. Conclusion: PCT levels only rose significantly during bacterial infections. In this study PCT levels >1.2 ng/ml were always evidence of bacterial infection and the cue for starting antibiotic treatment. PMID:12634233

    Ayrapetova, N.S.; Tkachenko, A.F.

    An attempt was made to optimize the therapy of chronic nonspecific pulmonary diseases using a combination of decimeter range waves (DRW) and broncholytic electroaerosols. The electroaerosols penetrate rapidly deep into the lungs up to the aveoli, combining the action of an electric charge with the pharmaceutical effect. In all, 232 patients were studied (94.8% with chronic bronchitis, 5.2% with chronic pneumonia) manifesting an active inflammatory process, disturbance of the immune status and diminished glucocorticoid activity. After 15 procedures of combined therapy, 88.5% of the patients showed improvement in their clinical status; 65.4% of the control group (receiving only the electroaerosol) also showed improvement. In this combined therapy, the antiinflammatory and immunosuppressive effect were achieved due to the action of DRW; the electroaerosols had a positive effect on the function state of the cardiorespiratory system. 11 references.

    In this study, the anti-nociceptive and anti-inflammatory effects of cyanocobalamin (Vit B12) against acute and chronic pain and inflammation were evaluated in mice. Vit B12 (0.87, 1 and 1.77 mg/kg) were injected intraperitoneally. The anti-nociceptive effects against acute pain were examined using hot-plate and writhing tests. The chronic pain was examined 14 days after sciatic nerve ligation using the hot-plate test. Morphine (10 mg/kg) was used as a positive control. Anti-inflammatory effects of Vit B12 against acute and chronic inflammation were assessed using xylene-induced edema in ears and granuloma caused by compressed cotton implantation, respectively. In these tests, sodium diclofenac (15 mg/kg) was used as a positive control. Vit B12 showed a dose related effect in acute anti-nociceptive test and increased the anti-nociceptive effect of morphine in chronic treatment. Vit B12 demonstrated an anti-nociceptive effect in chronic studies as single or continues daily treatment and increased significantly the anti-nociceptive effect of morphine. All doses of Vit B12 significantly decreased xylene-induced ear edema. Maximum anti-inflammatory effect (37.5%) was obtained at dose of 1 mg/kg. In chronic inflammation, Vit B12 significantly decreased granuloma formation in mice. In conclusion our work presents some experimental evidence supporting the administration of cyanocobalamin in controlling acute and chronic neuropathic pain. Cyanocobalamin may have anti-inflammatory effect. It may reduce tolerance to anti-nociceptive effect of morphine as well. PMID:22588629

    The combination of pogylated interferon (Peg-IFN) and ribavirin is the standard of care for chronic hepatitis C virus (HCV) infection treatment. In general, common side effects related to this combination therapy are mild and are very well tolerated. However, peripheral neuropathy including demyelinating polyneuropathy related to Peg-IFN is extremely rare. We present the first case of an acute inflammatory demyelinating polyneuropathy (AIDP)associated with Peg-IFN-α 2a (Pegasys) after 16 wk of a combination therapy with Pegasys and ribavirin in a 65-year-old woman with chronic HCV infection.She developed tingling, numbness, and weakness of her upper and lower extremities and was hospitalized for acute neurological deficits. Her clinical course,neurological findings, an electromyogram (EHG), nerve conductions studies (NCS), muscle biopsy, and a sural nerve biopsy were all consistent with AIDP likely related to Pegasys use. The patient recovered completely with the use of intravenous immunoglobulin (IVIG) including physical therapy and neurological rehabilitation. It is very important that gastroenterologists and/or hepatologists recognize this rare neurological complication related to Peg-IFN treatment very early, since it requires a prompt discontinuation of therapy including an immediate referral to a neurologist for the confirmation of diagnosis, management, and the prevention of long-term neurological deficits.

    Objective. Oxidative stress events have been implicated to occur and facilitate multiple failure modes of intracortical microelectrodes. The goal of the present study was to evaluate the ability of a sustained concentration of an anti-oxidant and to reduce oxidative stress-mediated neurodegeneration for the application of intracortical microelectrodes. Approach. Non-functional microelectrodes were implanted into the cortex of male Sprague Dawley rats for up to sixteen weeks. Half of the animals received a daily intraperitoneal injection of the natural anti-oxidant resveratrol, at 30 mg kg-1. The study was designed to investigate the biodistribution of the resveratrol, and the effects on neuroinflammation/neuroprotection following device implantation. Main results. Daily maintenance of a sustained range of resveratrol throughout the implantation period resulted in fewer degenerating neurons in comparison to control animals at both two and sixteen weeks post implantation. Initial and chronic improvements in neuronal viability in resveratrol-dosed animals were correlated with significant reductions in local superoxide anion accumulation around the implanted device at two weeks after implantation. Controls, receiving only saline injections, were also found to have reduced amounts of accumulated superoxide anion locally and less neurodegeneration than controls at sixteen weeks post-implantation. Despite observed benefits, thread-like adhesions were found between the liver and diaphragm in resveratrol-dosed animals. Significance. Overall, our chronic daily anti-oxidant dosing scheme resulted in improvements in neuronal viability surrounding implanted microelectrodes, which could result in improved device performance. However, due to the discovery of thread-like adhesions, further work is still required to optimize a chronic anti-oxidant dosing regime for the application of intracortical microelectrodes.

    Full Text Available Thousands of bacterial phylotypes colonise the human body and the host response to this bacterial challenge greatly influences our state of health or disease. The concept of infectogenomics highlights the importance of host genetic factors in determining the composition of human microbial biofilms and the response to this microbial challenge. We hereby introduce the term ‘genetic dysbiosis’ to highlight the role of human genetic variants affecting microbial recognition and host response in creating an environment conducive to changes in the normal microbiota. Such changes can, in turn, predispose to, and influence, diseases such as: cancer, inflammatory bowel disease, rheumatoid arthritis, psoriasis, bacterial vaginosis and periodontitis. This review presents the state of the evidence on host genetic factors affecting dysbiosis and microbial misrecognition (i.e. an aberrant response to the normal microbiota and highlights the need for further research in this area.

    Approximately one fourth of cases of inflammatory bowel disease (IBD) occur during childhood and children are more prone than their adult counterparts to have severe disease at presentation. To investigate these diseases MR imaging is no longer an emerging tool. Numerous reviews and articles have been published on this topic underlying the advances of imaging but also the complexity and the financial impact on management of such diseases. In children it seems reasonable to consider US as the first imaging examination to perform, especially when the diagnosis of IBD is unknown. However, we believe that recent and future technical progress, especially the ability of MR to display reproducible data, and the need for gold standard evaluation of new medical therapies will increase the role of MR enterography.

    Full Text Available Chronic intestinal pseudo-obstruction (CIPO is characterised by inadequate digestive tract motility and can lead to severely disordered motility. CIPO manifests as recurrent episodes of intestinal sub-occlusion without an anatomical obstruction. We present the case of a 41-year-old female, with severe chronic constipation and several episodes of intestinal sub-occlusion. Investigation revealed colonic inertia and marked distension of the small bowel and colon with no evidence of stenosis or obstructive lesions, compatible with CIPO. After several treatments were tried (domperidone, erythromycin, cisapride, octreotide, total enteral nutrition, with partial or no response, further work-up was done trying to identify an etiology. Gastrointestinal manometry showed neuropathic type abnormalities, transmural biopsy of the jejunum revealed degenerative enteric neuropathy and anti-HU antineuronal antibody screen was positive, suggesting an autoimmune type neuropathy with diffuse involvement of the digestive tract. Corticosteroids showed partial improvement of short duration and azathioprine was also tried but discontinued due to intolerance. Marked dietary intolerance and malnutrition lead to total parenteral nutrition (TPN at home since October 2011. Since then, symptoms and nutritional status improved, with rare episodes of pseudo-obstruction, not requiring hospitalisation.

    Escherichia coli(E. coli), and particularly the adherent invasive E. coli(AIEC) pathotype, has been increasingly implicated in the ethiopathogenesis of Crohn’s disease(CD). E. coli strains with similar pathogenic features to AIEC have been associated with other intestinal disorders such as ulcerative colitis, colorectal cancer, and coeliac disease, but AIEC prevalence in these diseases remains largely unexplored. Since AIEC was described one decade ago, substantial progress has been made in deciphering its mechanisms of pathogenicity. However, the molecular bases that characterize the phenotypic properties of this pathotype are still not well resolved. A review of studies focused on E. coli populations in inflammatory bowel disease(IBD) is presented here and we discuss about the putative role of this species on each IBD subtype. Given the relevance of AIEC in CD pathogenesis, we present the latest research findings concerning AIEC host-microbe interactions and pathogenicity. We also review the existing data regarding the prevalence and abundance of AIEC in CD and its association with other intestinal diseases from humans and animals, in order to discuss the AIEC disease- and hostspecificity. Finally, we highlight the fact that dietarycomponents frequently found in industrialized countries may enhance AIEC colonization in the gut, which merits further investigation and the implementation of preventative measures.

    The disease profile in the Indian population provides a unique opportunity for studying the host microbiome interaction in both infectious (amebiasis) and autoimmune diseases like inflammatory bowel disease (IBD) from a similar environment and genetic background. Analysis of fecal samples from untreated amebic liver abscess (ALA) patients, Entamoeba histolytica (Eh)-negative and -positive asymptomatic individuals, and pus samples from naive ALA patients revealed a significant reduction in Lactobacillus in asymptomatic individuals (Eh +ve) and ALA patients. Two anaerobic genera, namely Bacteroides and Peptostreptococcus, were detected in naive ALA pus samples. Analysis of fecal samples from amoebic colitis patients showed a significant decline in population of Bacteroides, Clostridium coccoides and leptum subgroup, Lactobacillus, Campylobacter, and Eubacterium, whereas a significant increase in Bifidobacterium was observed. Mucosa-associated bacterial flora analysis from IBD patients and healthy controls revealed a significant difference in concentration of bacteria among predominating and subdominating genera between ulcerative colitis (UC), Crohn's disease (CD) patients, and controls. In contrast to the mucosal studies, we found a significant increase in lactobacilli population in fecal samples of active UC patients. Another study revealed a significant decrease of Clostridium coccoides and leptum clusters in fecal samples of active UC patients along with decreased concentrations of fecal SCFAs, especially of n-butyrate, iso-butyrate, and acetate. We therefore found similar perturbations in gut microbiome in both infectious and autoimmune diseases, indicating inflammation to be the major driver for changes in gut microbiome. PMID:26994772

    Chronic obstructive pulmonary disease (COPD) is a debilitating, irreversible disease with currently available therapies targeting symptom control and exacerbation reduction. A need for alternative disease-modifying therapies remains, specifically those that may have antiinflammatory and immunomodulatory properties that impact the pathophysiologic components of COPD. Statin drugs, the current gold standard for the treatment of dyslipidemia and prevention of cardiovascular disease (CVD), contain properties that affect the inflammatory disease processes seen in COPD. Several retrospective studies have demonstrated that statins may have a benefit in the reduction of morbidity and mortality in patients with COPD. This has led to prospective trials evaluating the impact of statins on various COPD-related outcomes. This article reviews the current body of prospective evidence for use of statins in patients with COPD. A search of the PubMed/Medline database of English-language articles was conducted from 1964 through November 2015; references of relevant articles were also reviewed for qualifying studies. Prospective studies of all types relating to statin use in patients with COPD were included if they had COPD- or respiratory-related outcomes; ultimately, eight studies were identified for this review. Statin effects on exacerbation rates, mortality, and inflammatory markers in patients with COPD are discussed. Strong prospective evidence does not currently exist to suggest that statins provide a clinical benefit in patients with COPD who do not have other CVD risk factors. Benefits from statins that have been illustrated are likely explained by their impact on underlying CVD risk factors rather than the COPD disease process. An opportunity exists for unanswered questions to be addressed in future studies. PMID:26990316

    Mesenchymal stem cells (MSC) have been used to treat different clinical conditions although the mechanisms by which pathogenetic processes are affected are still poorly understood. We have previously analyzed the homing of bone marrow-derived MSC to diseased tissues characterized by a high degree of mononuclear cell infiltration and postulated that MSC might modulate inflammatory responses. Here, we demonstrate that MSC mitigate adverse tissue remodeling, improve organ function, and extend lifespan in a mouse model of inflammatory dilative cardiomyopathy (DCM). Furthermore, MSC attenuate Lipopolysaccharide-induced acute lung injury indicating a general role in the suppression of inflammatory processes. We found that MSC released sTNF-RI, which suppressed activation of the NFκBp65 pathway in cardiomyocytes during DCM in vivo. Substitution of MSC by recombinant soluble TNF-R partially recapitulated the beneficial effects of MSC while knockdown of TNF-R prevented MSC-mediated suppression of the NFκBp65 pathway and improvement of tissue pathology. We conclude that sTNF-RI is a major part of the paracrine machinery by which MSC effect local inflammatory reactions. PMID:27435289

    Several studies indicate that low level laser therapy (LLLT) accelerates the healing process, however, for a determined pathology, dosimetry remains difficult to be established. To understand the tissue optical properties under different conditions is extremely relevant since the dose delivered to the target tissue is known to be critical. The skin pigmentation influence on the laser attenuation is not yet well established on different mice lineages or human ethnical groups, making the dose problematic. Along the same line, inflammatory processes may cause similar problems since the tissues in this condition change their optical properties due to inflammatory cell accumulation. This work evaluated the attenuation pattern of a HeNe laser (λ=632.8 nm) using ex vivo skin samples from Balb/C and C57BL/6 mice under inflammatory stages induced in their paw by local carrageenan inoculation. The samples were placed between two microscope slides, and a CCD camera was placed orthogonal to the beam path. The intensity distribution of the scattered light was photographed in grayscale and analyzed by ImageJ software. Our findings suggest that even slight differences of the epithelial pigmentation could result in a relevant dose loss delivered to the deeper tissues. The increase of the inflammatory cell density in the connective tissue indicated a highly scattering area also resulting in a dose loss for the deeper tissues when compared to control group.

    Lung ischemia-reperfusion (IR) complicates numerous clinical processes, such as cardiac arrest, transplantation, and major trauma. These conditions generate sterile inflammation, which can cause or worsen acute lung injury. We previously reported that lung and systemic inflammation in a mouse model of ventilated lung IR depends on Toll-like receptor 4 (TLR-4) signaling and the presence of alveolar macrophages. Here, we tested the hypothesis that the intestinal microbiome has a role in influencing the inflammatory response to lung IR. Lung IR was created in intubated mechanically ventilated mice via reversible left pulmonary artery occlusion followed by reperfusion. Inflammatory markers and histology were tracked during varying periods of reperfusion (from 1 to 24 h). Separate groups of mice were given intestinally localized antibiotics for 8 to 10 weeks and then were subjected to left lung IR and analysis of lungs and plasma for markers of inflammation. Alveolar macrophages from antibiotic-treated or control mice were tested ex vivo for inflammatory responses to bacterial TLR agonists, namely, lipopolysaccharide and Pam3Cys. We found that inflammation generated by left lung IR was rapid in onset and dissipated within 12 to 24 h. Treatment of mice with intestinally localized antibiotics was associated with a marked attenuation of circulating and lung inflammatory markers as well as reduced histologic evidence of infiltrating cells and edema in the lung after IR. Alveolar macrophages from antibiotic-treated mice produced less cytokines ex vivo when stimulated with TLR agonists as compared with those from control mice. Our data indicate that the inflammatory response induced by nonhypoxic lung IR is transient and is strongly influenced by intestinal microbiota. Furthermore, these data suggest that the intestinal microbiome could potentially be manipulated to attenuate the post-IR pulmonary inflammatory response. PMID:26196836

    Full Text Available Large vein endothelium plays important roles in clinical diseases such as chronic venous disease (CVD and thrombosis; thus to characterize CVD vein endothelial cells (VEC has a strategic role in identifying specific therapeutic targets. On these bases we evaluated the effect of the natural anti-inflammatory compounds α-Lipoic acid and Ginkgoselect phytosome on cytokines/chemokines released by CVD patient-derived VEC. For this purpose, we characterized the levels of a panel of cytokines/chemokines (n=31 in CVD patients’ plasma compared to healthy controls and their release by VEC purified from the same patients, in unstimulated and TNF-α stimulated conditions. Among the cytokines/chemokines released by VEC, which recapitulated the systemic profile (IL-8, TNF-α, GM-CSF, INF-α2, G-CSF, MIP-1β, VEGF, EGF, Eotaxin, MCP-1, CXCL10, PDGF, and RANTES, we identified those targeted by ex vivo treatment with α-Lipoic acid and/or Ginkgoselect phytosome (GM-CSF, G-CSF, CXCL10, PDGF, and RANTES. Finally, by investigating the intracellular pathways involved in promoting the VEC release of cytokines/chemokines, which are targeted by natural anti-inflammatory compounds, we documented that α-Lipoic acid significantly counteracted TNF-α-induced NF-κB and p38/MAPK activation while the effects of Ginkgo biloba appeared to be predominantly mediated by Akt. Our data provide new insights into the molecular mechanisms of CVD pathogenesis, highlighting new potential therapeutic targets.

    Cannabinoid CB(2) receptor activation by selective agonists has been shown to produce analgesic effects in preclinical models of inflammatory, neuropathic, and bone cancer pain. In this study the effect of a novel CB(2)agonist (MT178) was evaluated in different animal models of pain. First of all, in vitro competition binding experiments performed on rat, mouse, or human CB receptors revealed a high affinity, selectivity, and potency of MT178. The analgesic properties of the novel CB(2) agonist were evaluated in various in vivo experiments, such as writhing and formalin assays, showing a good efficacy comparable with that produced by the nonselective CB agonist WIN 55,212-2. A dose-dependent antiallodynic effect of the novel CB(2) compound in the streptozotocin-induced diabetic neuropathy was found. In a bone cancer pain model and in the acid-induced muscle pain model, MT178 was able to significantly reduce mechanical hyperalgesia in a dose-related manner. Notably, MT178 failed to provoke locomotor disturbance and catalepsy, which were observed following the administration of WIN 55,212-2. CB(2) receptor mechanism of action was investigated in dorsal root ganglia where MT178 mediated a reduction of [(3)H]-d-aspartate release. MT178 was also able to inhibit capsaicin-induced substance P release and NF-κB activation. These results demonstrate that systemic administration of MT178 produced a robust analgesia in different pain models via CB(2) receptors, providing an interesting approach to analgesic therapy in inflammatory and chronic pain without CB(1)-mediated central side effects.

    Chronic obstructive pulmonary disease (COPD) is a complex chronic inflammatory disease of the respiratory system affecting primarily distal respiratory pathways and lung parenchyma. This work was designed as a case-control study aimed at investigating the association of COPD with polymorphisms in inflammatory and immune response genes (JAK1, JAK3, STAT1, STAT3, NFKB1, IL17A, ADIPOQ, ADIPOR1, etc.) in Tatar population from Russia. Ten SNPs (rs310216, rs3212780, rs12693591, rs2293152, rs28362491, rs4711998, rs1974226, rs1501299, rs266729, and rs12733285) were genotyped by the real-time polymerase chain reaction (TaqMan assays) in a case-control study (425 COPD patients and 457 in the control group, from Ufa, Russia). Logistic regression was used to detect the association of SNPs in different models. Linear regression analyses were performed to estimate the relationship between SNPs and lung function parameters and pack-years. In Tatar population, significant associations of JAK1 (rs310216) (P = 0.0002, OR 1.70 in additive model), JAK3 (rs3212780) (P = 0.001, OR 1.61 in dominant model), and IL17A (rs1974226) (P = 0.0037, OR 2.31 in recessive model) with COPD were revealed. The disease risk was higher in carriers of insertion allele of NFKB1 (rs28362491) (P = 0.045, OR 1.22). We found a significant gene-by-environment interaction of smoking status and IL17A (rs1974226) (P interact = 0.016), JAK3 (rs3212780) (P interact = 0.031), ADIPOQ (rs266729) (P interact = 0.013), and ADIPOR1 (rs12733285) (P interact = 0.018). The relationship between the rs4711998, rs1974226, rs310216, rs3212780, rs28362491, and smoking pack-years was found (P = 0.045, P = 0.004, P = 0.0005, P = 0.021, and P = 0.042). A significant genotype-dependent variation of forced vital capacity was observed for NFKB1 (rs28362491) (P = 0.017), ADIPOR1 (rs12733285) (P = 0.043), and STAT1 (rs12693591) (P = 0.048). The genotypes of STAT1 (rs12693591) (P = 0.013) and JAK1 (rs

    Tumor necrosis factor alpha (TNF-alpha) plays an important role in the pathogenesis of chronic inflammatory diseases, i.e., rheumatoid arthritis (RA), ankylosing spondylitis (AS), Crohn's disease (CD), and ulcerative colitis (UC). Anti-TNF-alpha strategies are successfully used in their treatment. However, their effect on heart function is still uncertain. The objectives of the study were to examine the acute and long-term effect of infliximab on the heart morphology and function in patients with chronic inflammatory disorders. Thirty-one patients (21 men and 10 women) were included. Ten percent of them were diagnosed with RA, 22.5 % with AS, 22.5 % with CD, and 45 % with UC, respectively. N-terminal fragment of pro-brain natriuretic peptide (NT-proBNP) was measured before and immediately after infliximab administration at the beginning of the study and in the sixth and 12th months. Echocardiography was performed at baseline and in the sixth and 12th months. There was a significant increase in NT-proBNP after the first infliximab infusion (88.40 ± 14.09 vs. 95.24 ± 14.28 pg/ml, p = 0.0046) and similar response was detected after each infusion in the sixth and 12th months. Plasma NT-proBNP slightly but not significantly decreased (88.40 ± 14.09 vs. 81.74 ± 23.14 pg/ml, p = 0.583, and 88.40 ± 14.09 vs. 56.83 ± 17.77 pg/ml, p = 0.0576, in the sixth and 12th months, respectively). There were no significant changes in echocardiographic structural and functional parameters of the left ventricle during follow-up. Plasma NT-proBNP mildly but significantly increases immediately after infliximab infusion. However, long-term infliximab administration does not deteriorate both cardiac morphology and function.

    CIDP is a motor and sensory neuropathy characterized by chronic, step-wised, or relapsing progression. Both cellular and humoral autoimmunity targeting the myelin sheath is assumed as the main mechanism of CIDP pathogenesis. While the AAN diagnostic criteria have been the main method in Japan, the EFNS/PNS criteria recently replaced them because of their good diagnostic sensitivity and clinical superiority. The first-line therapy for CIDP patients in Japan is intravenous immunoglobulin (IVIg), corticosteroids, and phasmapheresis, the same as in other countries. Regarding therapeutics, two major differences between Japan and other countries exist. Firstly, while half-dose IVIg (1 g/kg body weight) every three weeks was established as maintenance therapy as a result of the ICE study in 2008, full-dose IVIg (2 g/kg body weight over five days) once a month is still accepted in Japan for highly recurrent patients. Secondly, Japanese clinicians prefer immune adsorption plasmapheresis (IAPP) instead of plasma exchange (PE) among three types of plasmapheresis (IAPP, PE, and double-filtered plasmapheresis [DFPP]). These differences could be due to the characteristic and independent health insurance system in Japan. Using recent knowledge and diagnostic criteria, clinical trials have been based on these global platforms. Recently, efforts have been made to share these platforms with a worldwide vision.

    Objective: To study the anti-inflammatory activity of Lovastatin, Simvastatin, Atorvastatin, and Rosuvastatin on acute and chronic models of inflammation, to compare with the effect of Diclofenac sodium and amongst themselves in rats. Methods: Carrageenin induce rat paw edema method in which 5 animals of each group (6 groups) received orally 4% gum acacia, Diclofenac and 4 statins respectively 1 h before Carrageenin injection in paw. The paw edema volume measured with plethysmograph after 3 h and percentage inhibition of edema in various groups calculated. Rexin pellet granuloma method in which 4 rexin pellets were implanted into dorsum of skin of each rat of 6 groups (n=5) including control, Diclofenac and 4 statin groups respectively. Rats were orally fed with drugs daily for 7 days and on 8th day rexin pellets were removed after sacrificing the rat and dried in incubator 60oC overnight. Pellets were then weighed and percentage inhibition of granulation tissue was calculated and sent for histopathological examination.Results:All the 4 statins showed significant anti-inflammatory activity in the present study in both acute as well as chronic models of inflammation. The anti-inflammatory activity of the 4 statins was significant on comparison with Diclofenac. Lovastatin and Simvastatin demonstrated 10-20% more anti-inflammatory activity than Atorvastatin and Rosuvastatin. Conclusions: The present study revealed the anti-inflammatory effect of statins and thus suggests that the statins have a potential anti-atherosclerotic activity along with its lipid lowering property.

    Multiple sclerosis (MS) and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) represent chronic, autoimmune demyelinating disorders of the central and peripheral nervous system. Although both disorders share some fundamental pathogenic elements, treatments do not provide uniform effects across both disorders. We aim at providing an overview of current and future disease-modifying strategies in these disorders to demonstrate communalities and distinctions. Intravenous immunoglobulins (IVIG) have demonstrated short- and long-term beneficial effects in CIDP but are not effective in MS. Dimethyl fumarate (BG-12), teriflunomide and laquinimod are orally administered immunomodulatory drugs that are already approved or likely to be approved in the near future for the basic therapy of patients with relapsing-remitting MS (RRMS) due to positive results in Phase III clinical trials. However, clinical trials with these drugs in CIDP have not (yet) been initiated. Natalizumab and fingolimod are approved for the treatment of RRMS, and trials to evaluate their safety and efficacy in CIDP are now planned. Alemtuzumab, ocrelizumab and daclizumab respresent monoclonal antibodies in advanced stages of clinical development for their use in RRMS patients. Attempts to study the safety and efficacy of alemtuzumab and B cell-depleting anti-CD20 antibodies, i.e. rituximab, ocrelizumab or ofatumumab, in CIDP patients are currently under way. We provide an overview of the mechanism of action and clinical data available on disease-modifying immunotherapy options for MS and CIDP. Enhanced understanding of the relative effects of therapies in these two disorders may aid rational treatment selection and the development of innovative treatment approaches in the future.

  18. Polymorphism in the alpha cardiac muscle actin 1 gene is associated to susceptibility to chronic inflammatory cardiomyopathy.

    Amanda Farage Frade

    Full Text Available AIMS: Chagas disease, caused by the protozoan Trypanosoma cruzi is endemic in Latin America, and may lead to a life-threatening inflammatory dilated, chronic Chagas cardiomyopathy (CCC. One third of T. cruzi-infected individuals progress to CCC while the others remain asymptomatic (ASY. A possible genetic component to disease progression was suggested by familial aggregation of cases and the association of markers of innate and adaptive immunity genes with CCC development. Since mutations in multiple sarcomeric genes, including alpha-cardiac actin (ACTC1 have been involved in hereditary dilated cardiomyopathy, we investigated the involvement of the ACTC1 gene in CCC pathogenesis. METHODS AND RESULTS: We conducted a proteomic and genetic study on a Brazilian study population. The genetic study was done on a main cohort including 118 seropositive asymptomatic subjects and 315 cases and the replication was done on 36 asymptomatic and 102 CCC cases. ACTC1 protein and mRNA levels were lower in myocardial tissue from patients with end-stage CCC than those found in hearts from organ donors. Genotyping a case-control cohort of CCC and ASY subjects for all informative single nucleotide polymorphism (SNP in the ACTC1 gene identified rs640249 SNP, located at the 5' region, as associated to CCC. Associations are borderline after correction for multiple testing. Correlation and haplotype analysis led to the identification of a susceptibility haplotype. Functional assays have shown that the rs640249A/C polymorphism affects the binding of transcriptional factors in the promoter regions of the ACTC1 gene. Confirmation of the detected association on a larger independent replication cohort will be useful. CONCLUSIONS: Genetic variations at the ACTC1 gene may contribute to progression to chronic Chagas Cardiomyopathy among T. cruzi-infected patients, possibly by modulating transcription factor binding to ACTC1 promoter regions.

  19. Pharmacokinatics of sup(99m)Tc tetracycline in tumours and inflammatory - necrotic processes (experimental investigation)

    International Nuclear Information System (INIS)

    Distribution, regularities in elimination and the features of sup(99m)Tc-tetracycline metabolism were studied in rats with sarcoma M-1 and in rats with inflammatory-necrotic processes. In rats with sarcoma M-1 radioactivity accumulated for 15 minutes after intravenous admonistration of the preparation. The greatest initial activity was determined in the kidneys, liver, lungs and the tumour. Rapid metabolism of the preparation in the body and especially short half-life of the isotope Tsub(1/2) phus (6h) was the cause of short Tsub(1/2) eff (8h) and T sub(1/2) biol (24h). In the femoral muscles in which the inflammatory-necrotic processes were induced by ligation for 2-5 days, the accumulation of the label was 2.5-2.9 times higher than that in intact muscles

    Full Text Available Paricalcitol, a selective vitamin D receptor (VDR activator used for treatment of secondary hyperparathyroidism in chronic kidney disease (CKD, has been associated with survival advantages, suggesting that this drug, beyond its ability to suppress parathyroid hormone, may have additional beneficial actions. In this prospective, nonrandomised, open-label, proof-of-concept study, we evaluated the hypothesis that selective vitamin D receptor activation with paricalcitol is an effective target to modulate inflammation in CKD patients. Eight patients with an estimated glomerular filtration rate between 15 and 44 mL/min/1.73 m2 and an intact parathyroid hormone (PTH level higher than 110 pg/mL received oral paricalcitol (1 μg/48 hours as therapy for secondary hyperparathyroidism. Nine patients matched by age, sex, and stage of CKD, but a PTH level <110 pg/mL, were enrolled as a control group. Our results show that five months of paricalcitol administration were associated with a reduction in serum concentrations of hs-CRP (13.9%, P<0.01, TNF-α (11.9%, P=0.01, and IL-6 (7%, P<0.05, with a nonsignificant increase of IL-10 by 16%. In addition, mRNA expression levels of the TNFα and IL-6 genes in peripheral blood mononuclear cells decreased significantly by 30.8% (P=0.01 and 35.4% (P=0.01, respectively. In conclusion, selective VDR activation is an effective target to modulate inflammation in CKD.

    We retrospectively analyzed 146 patients fulfilling the European Federation of Neurological Societies and the Peripheral Nerve Society (EFNS/PNS) criteria for definite chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) to (1) evaluate the relevance of these criteria, (2) assess the frequency of CIDP variants, and (3) determine the response to treatment and the prognosis. We found that 75% of these patients fulfilled the main EFNS/PNS clinical and electrophysiological criteria (type I). The remaining patients were diagnosed using laboratory tools as supportive criteria. The common form of CIDP represented 51% of patients. We observed a high frequency of the sensory variant (35% of patients) and the rapid onset form (18%). A positive response to treatment was observed in 87% of patients, with a similar efficacy of prednisone and IVIg. However, in the long term, 40% of treated patients remained dependent on treatment. The IVIg dependency rate was higher than the prednisone or plasma exchange dependency rate (55%, 18%, and 23%, respectively; p = 0.0054). Severe handicap was observed in 24% of patients.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an immune-mediated peripheral nervous system disease. CD4+CD25+ T regulatory cells (Tregs) have been unequivocally shown to be critical in maintaining immune tolerance and preventing auto-immune diseases by suppressing self-reactive T cells. Thus, we hypothesized that the numbers and/or the function of Tregs would be deranged during the progressive or relapse phases of CIDP. The number of Tregs was determined by flow cytometry according to their characteristic CD4+CD25(high) membrane phenotype. Functional characterization of Tregs was analyzed by suppression of proliferation and secretion of cytokines by co-cultured effector CD4+CD25- T cells. FOXP3 message expression level was assessed by quantitative real-time polymerase chain reaction. The results showed significant reduction in both the number and the suppressive function of Tregs in the patients with CIDP compared with healthy controls. Also, Tregs isolated from CIDP patients expressed lower levels of FoxP3 mRNA. During the progressive or the relapsing phases of CIDP, the number of Tregs was reduced, and the suppressive function of them decreased. These findings may be helpful to our understanding of the possible role of Tregs in the pathogenesis of CIDP.

    Full Text Available OBJECTIVE: Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP is currently classified into clinical subtypes, including typical and atypical forms (multifocal acquired demyelinating sensory and motor neuropathy (MADSAM and distal acquired demyelinating symmetric neuropathy (DADS. The aim of this study was to elucidate the patterns and severity of breakdown of the blood-nerve barrier (BNB in each CIDP subtype. METHODS: We evaluated the effects of sera obtained from patients with typical CIDP, MADSAM and DADS and control subjects on the expression levels of tight junction proteins and transendothelial electrical resistance (TEER value in human peripheral nerve microvascular endothelial cells (PnMECs. RESULTS: The sera obtained from the patients with the three clinical phenotypes of CIDP decreased the amount of claudin-5 protein levels and TEER values in the PnMECs. In addition, the sera obtained from typical CIDP patients more prominently reduced claudin-5 protein levels and TEER values in the PnMECs than did that obtained from the MADSAM and DADS patients. Furthermore, the severity of BNB disruption after exposure to the sera was associated with higher Hughes grade, lower MRC score, more pronounced slowing of motor nerve conduction in the median nerve and higher frequency of abnormal temporal dispersion. CONCLUSIONS: Sera derived from typical CIDP patients destroy the BNB more severely than those from MADSAM or DADS patients. The extent of BNB disruption in the setting of CIDP is associated with clinical disability and demyelination in the nerve trunk. These observations may explain the phenotypical differences between CIDP subtypes.

    Full Text Available Objective. This cross-sectional study analyzes the pattern of ultrasound peripheral nerve alterations in patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP and multifocal motor neuropathy (MMN at different stages of functional disability. Material and Methods. 22 CIDP and 10 MMN patients and a group of 70 healthy controls were evaluated with an ultrasound scan of the median, ulnar, peroneal, tibial, and sural nerves. Results were correlated with clinical disability scales and nerve conduction studies. Results. Patients with intermediate functional impairment showed relatively larger cross-sectional areas than subjects with either a milder (p<0.05 or more severe impairment (p<0.05, both in CIDP and in MMN. In addition, MMN was associated with greater side-to-side intranerve variability (p<0.05, while higher cross-sectional areas were observed in CIDP (p<0.05 and in nerve segments with predominantly demyelinating features (p<0.05. Higher CSA values were observed in nerves with demyelinating features versus axonal damage (p<0.05 for CIDP; p<0.05 for MMN. Discussion and Conclusions. Greater extent of quantitative and qualitative US alterations was observed in patients at intermediate versus higher functional disability and in nerves with demyelinating versus axonal damage. CIDP and MMN showed differential US aspects, with greater side-to-side intranerve variability in MMN and higher cross-sectional areas in CIDP.

  6. Odontogenic Inflammatory Processes of Head and Neck in Computed Tomography Examinations

    International Nuclear Information System (INIS)

    Infections of odontogenic origin are the most common cause of inflammatory disease of head and neck region. Computed tomography allows for defining localization and extent of inflammatory lesions, visualizes soft tissue involvement, presence of an abscess or an osteolytic lesion around causative tooth. The aim of this study was to assess pathways, by which odontogenic infections spread into respective deep head and neck structures in computed tomography examination, taking into account the following criteria: frequency of involvement of respective deep cervical spaces, possibility to determine a probable causative tooth and concordance with the results of clinical examination. Thirty-eight patients cervicofacial inflammatory disease had undergone CT examination of head and neck region with a 64-slice CT scanner after intravenous contrast administration. Abscess was reported in 30 (79%) cases, while inflammatory infiltration was diagnosed in remaining 8 (21%) patients. There was full concordance between radiological report and intraoperative report In 33 cases (87%). The most commonly involved cervical space was masticator space – 31 patients (82%), followed by submandibular space – 27 patients (71%). Dental examination was impossible in 29 patient because of trismus. During analysis of CT studies we evaluated maxillary and mandibular alveolar processes for presence of osteolytic bone lesions around causative teeth roots and we found them in 30 cases (79%). In 32 cases (84%) cervicofacial infection were of mandibular odontogenic origin. In most cases CT study in patients suspected of odontogenic craniofacial infection revealed presence of an abscess, needing urgent surgery. Inflammatory infiltration of dental origin most frequently involves masticator space, followed by submandibular space. In most cases CT scanning allows for identification of causative teeth, especially when trismus makes detailed clinical examination impossible

    Full Text Available Chronic ethanol abuse is known to increase susceptibility to infections after injury, in part, by modification of macrophage function. Several intracellular signalling mechanisms are involved in the initiation of inflammatory responses, including the nuclear factor-κB (NF-κB pathway. In this study, we investigated the systemic and hepatic effect of chronic ethanol feeding on in vivo activation of NF-κB in NF-κBEGFP reporter gene mice. Specifically, the study focused on Kupffer cell proinflammatory cytokines IL-6 and TNF-α and activation of NF-κB after chronic ethanol feeding followed by in vitro stimulation with lipopolysaccharide (LPS. We found that chronic ethanol upregulated NF-κB activation and increased hepatic and systemic proinflammatory cytokine levels. Similarly, LPS-stimulated IL-1β release from whole blood was significantly enhanced in ethanol-fed mice. However, LPS significantly increased IL-6 and TNF-α levels. These results demonstrate that chronic ethanol feeding can improve the responsiveness of macrophage LPS-stimulated IL-6 and TNF-α production and indicate that this effect may result from ethanol-induced alterations in intracellular signalling through NF-κB. Furthermore, LPS and TNF-α stimulated the gene expression of different inflammatory mediators, in part, in a NF-κB-dependent manner.

    Full Text Available A large role in the pathogenesis of osteoarthrosis (OA is assigned to proinflammatory cytokines, such as interleukin 1 (IL1 and tumor necrosis factor-α, which activate catabolic processes in the cartilaginous tissue and subchondral bone. Diacerein is a medication that is able to block IL1 receptors, to lower the activity of metalloproteinases and nitric oxide, and thus to prevent joint inflammation and destruction in OA.

    Chronic otitis media with effusion (OME) is associated with irreversible changes in the middle ear, sometimes leading to hearing loss and abnormal language development in children. While the pathogenesis of OME is not fully understood, inflammatory and allergic factors are thought to be involved. The study aimed to investigate the role of cytokines in the local development of chronic OME, and assess differences in the cytokine profiles between atopic and non-atopic children. 84 atopic and non-atopic children with chronic OME (mean age of 6 years 7 months) were studied. Age-matched children with hypertrophy of the adenoids and Eustachian tube dysfunction served as the control group. The number of past acute otitis media (AOM) episodes, their age, and the type of effusion were recorded for all children. Pro-inflammatory cytokine concentrations (TNF-α, IL-1β, IL-6 and IL-8) were determined and the presence of pathogenic bacteria in the patients' effusions was examined. High concentrations of TNF-α, IL-1β, IL-6 and IL-8 were found in the effusions in all children with chronic OME, with the highest levels observed in the non-atopic group. The atopic group showed persistently high IL-1β levels, while in the non-atopic children, IL-1β and TNF-α levels positively correlated with the patient's age and the number of past AOM episodes. Pathogenic bacteria were more frequently isolated from effusions in non-atopic children. In both atopic and non-atopic children, pro-inflammatory cytokines are found at high concentrations. This argues in favor of instituting anti-inflammatory management for treating OME, regardless of atopy. PMID:26078091

    CONCLUSION: We could demonstrate for the first time that an improvement in median overall survival with gemcitabine is significantly abolished by a persistent mild chronic pancreatitis and a systemic inflammatory response syndrome. In particular, the inflammation biomarkers C-reactive protein, IL-6, and IL-1α could indicate the prognostic benefit of gemcitabine chemotherapy and should now be tested in prospective patient-controlled trials.

    Biosimilars for psoriasis treatment are currently being developed. Comparison of their efficacy and safety is a challenge. For approval, the European Medicines Agency (EMA) considers indirect evidence from other indications (for example, rheumatoid arthritis) as sufficient. Systematic review of biosimilars for psoriasis and other indications, review of ongoing trials in trial registers. Systematic search for randomized controlled trials (RCT) on biosimilars to adalimumab, etanercept, infliximab, and ustekinumab compared to their reference medication: (1) Publications in Medline, Medline In-Process, Embase, Cochrane Library (efficacy, safety, immunogenicity) and (2) ongoing studies in clinical trial registers. No trials on biosimilars in psoriasis patients were identified. As to the infliximab biosimilar, there is data on patients with ankylosing spondylitis and rheumatoid arthritis, indicating no clinically relevant differences regarding efficacy and safety. Currently, there are two registered studies of an adalimumab biosimilar and one study of an etanercept biosimilar in psoriasis patients. Further ongoing studies on biosimilars to adalimumab, etanercept, and infliximab - all in rheumatoid arthritis patients - were identified. There is currently only limited data regarding RCTs with biosimilars. Provision of further clinical data and inclusion of patients in patient registers will be crucial. PMID:25819235

  20. Therapeutic helminth infection of macaques with idiopathic chronic diarrhea alters the inflammatory signature and mucosal microbiota of the colon.

    Directory of Open Access Journals (Sweden)

    Mara Jana Broadhurst

    Full Text Available Idiopathic chronic diarrhea (ICD is a leading cause of morbidity amongst rhesus monkeys kept in captivity. Here, we show that exposure of affected animals to the whipworm Trichuris trichiura led to clinical improvement in fecal consistency, accompanied by weight gain, in four out of the five treated monkeys. By flow cytometry analysis of pinch biopsies collected during colonoscopies before and after treatment, we found an induction of a mucosal T(H2 response following helminth treatment that was associated with a decrease in activated CD4(+ Ki67+ cells. In parallel, expression profiling with oligonucleotide microarrays and real-time PCR analysis revealed reductions in T(H1-type inflammatory gene expression and increased expression of genes associated with IgE signaling, mast cell activation, eosinophil recruitment, alternative activation of macrophages, and worm expulsion. By quantifying bacterial 16S rRNA in pinch biopsies using real-time PCR analysis, we found reduced bacterial attachment to the intestinal mucosa post-treatment. Finally, deep sequencing of bacterial 16S rRNA revealed changes to the composition of microbial communities attached to the intestinal mucosa following helminth treatment. Thus, the genus Streptophyta of the phylum Cyanobacteria was vastly increased in abundance in three out of five ICD monkeys relative to healthy controls, but was reduced to control levels post-treatment; by contrast, the phylum Tenericutes was expanded post-treatment. These findings suggest that helminth treatment in primates can ameliorate colitis by restoring mucosal barrier functions and reducing overall bacterial attachment, and also by altering the communities of attached bacteria. These results also define ICD in monkeys as a tractable preclinical model for ulcerative colitis in which these effects can be further investigated.

    Inflammatory bowel disease (IBD) presents intense inflammatory infiltrate, crypt abscesses, ulceration and even loss of function. Despite the clinical relevance of IBD, its current therapy remains poorly effective. Infrared wavelength phototherapy shows therapeutic potential on inflammation. Our goal was to evaluate whether light-emitting diodes (LED) at 940nm are capable of mitigating the colitis-induced inflammatory process in mice. Forty male Swiss mice were assigned into five groups: control; control treated with LED therapy; colitis without treatment; colitis treated with LED therapy; colitis treated with Prednisolone. Experimental colitis was induced by acetic acid 7.5% (pH2.5) rectal administration. LED therapy was performed with light characterized by wavelength of 940nm, 45nm bandwidth, intensity of 4.05J/cm(2), total power of 270mW and total dose of 64.8J for 4min in a single application. Colitis-induced intestinal transit delay was inhibited by LED therapy. Colitis caused an increase of colon dimensions (length, diameter, total area) and colon weight (edema), which were inhibited by LED therapy. LED therapy also decreased colitis-induced tissue gross lesion, myeloperoxidase activity, microscopic tissue damage score and the presence of inflammatory infiltrate in all intestinal layers. Furthermore, LED therapy inhibited colitis-induced IL-1β, TNF-α, and IL-6 production. We conclude LED therapy at 940nm inhibited experimental colitis-induced colon inflammation in mice, therefore, rendering it a promising therapeutic approach that deserves further investigation.

  3. Curcumin protects against radiation-induced acute and chronic cutaneous toxicity in mice and decreases mRNA expression of inflammatory and fibrogenic cytokines

    International Nuclear Information System (INIS)

    Purpose: To determine whether curcumin ameliorates acute and chronic radiation skin toxicity and to examine the expression of inflammatory cytokines (interleukin [IL]-1, IL-6, IL-18, IL-1Ra, tumor necrosis factor [TNF]-α, and lymphotoxin-β) or fibrogenic cytokines (transforming growth factor [TGF]-β) during the same acute and chronic phases. Methods and Materials: Curcumin was given intragastrically or intraperitoneally to C3H/HeN mice either: 5 days before radiation; 5 days after radiation; or both 5 days before and 5 days after radiation. The cutaneous damage was assessed at 15-21 days (acute) and 90 days (chronic) after a single 50 Gy radiation dose was given to the hind leg. Skin and muscle tissues were collected for measurement of cytokine mRNA. Results: Curcumin, administered before or after radiation, markedly reduced acute and chronic skin toxicity in mice (p < 0.05). Additionally, curcumin significantly decreased mRNA expression of early responding cytokines (IL-1 IL-6, IL-18, TNF-α, and lymphotoxin-β) and the fibrogenic cytokine, TGF-β, in cutaneous tissues at 21 days postradiation. Conclusion: Curcumin has a protective effect on radiation-induced cutaneous damage in mice, which is characterized by a downregulation of both inflammatory and fibrogenic cytokines in irradiated skin and muscle, particularly in the early phase after radiation. These results may provide the molecular basis for the application of curcumin in clinical radiation therapy

    -cell-attracting chemokine, eotaxin, IL-6, and stem cell factor are inversely associated with forced expiratory volume in 1 second and peak oxygen uptake change, whereas smoking is related to eotaxin and hepatocyte growth factor changes. Enrichment pathways and network analyses reveal the potential involvement of specific inflammatory and immune process pathways in COPD. Identified network interaction and regulation of different cytokines would pave the way for deeper insight into mechanisms of the disease process.

    Atherosclerosis is a chronic disease developing through decades with two life-threatening complications: myocardial infarction and stroke. Oxidized low-density lipoproteins (oxLDL) produced by oxidative modifications of LDL in the subendothelial space have been demonstrated to be critically involved in atherogenesis through their intensive pro-inflammatory activity. Recently, it was shown that oxLDL have an apoptosis-inducing effect in T cells depending on time and degree of oxidation. The goal of the current study is to elucidate the molecular mechanisms underlying the apoptotic-inducing effects of oxLDL on T lymphocytes. T cells of young and elderly subjects were incubated for various periods of time with LDL oxidized to various degrees. The proliferation, the apoptosis, the MAPK ERK1/2 activation and the expression of the Bcl-2 protein family members were measured upon different LDL treatments. Thus, more the LDL are oxidized more they induce apoptosis and this effect is highly accentuated with aging. The oxLDL decrease the activation of the surviving molecule ERK1/2 and modulate the ratio of Bax/Bcl-2 towards a pro-apoptotic profile, which is also accentuated with aging. These results partly explain why atherosclerosis is increasing with aging concomitantly to its complications.

    Full Text Available INTRODUCTION: We aimed to determine whether the clinical characteristics and electrodiagnostic classification of nerve injury, and response to treatment differed in patients diagnosed with chronic inflammatory demyelinating polyneuropathy (CIDP with and without diabetes. METHODS: CIDP patients with diabetes (CIDP+DM (n = 67 and without diabetes (CIDP-DM (n = 67 underwent clinical examination and nerve conduction studies (NCS. CIDP-DM patients were selected using age and gender matching with the existing CIDP+DM cohort. Patients treated with immunotherapies were classified as responders (R (n = 46 or non-responders (NR (n = 54 based on clinical response to treatment. The groups were compared using analysis of variance, contingency tables and Kruskal-Wallis analyses. RESULTS: CIDP+DM subjects had more severe neuropathy based on higher lower limb vibration potential thresholds (VPT(p = 0.004, higher Toronto Clinical Neuropathy Score (TCNS (p = 0.0009, more proximal weakness (p = 0.03, more gait abnormality (p = 0.03 and more abnormal NCS. CIDP+DM subjects had more abnormal sural NCS with lower sural sensory nerve action potential amplitudes (2.4±3.0 µV, 6.6±6.0 µV, p<0.0001 and slower sural nerve conduction velocities (38.6±5.4 m/s, 41.0±5.3 m/s, p = 0.04. CIDP-DM subjects were more likely to receive immune therapies (93% vs 57%, p = <0.0001, despite no significant differences in treatment responder rates (p = 0.71. Patients who responded to therapy had shorter duration of CIDP than non-responders (8.0±6.0 y vs 11.9±7.6 y, p = 0.004. DISCUSSION: The clinical phenotype and electrophysiological profile of CIDP patients differs according to the presence or absence of diabetes. Despite CIDP+DM patients having more severe clinical and electrophysiological neuropathy, they are less likely to receive disease-modifying/specific therapy, yet have similar response rates to treatment as those without

    The risk of infection associated with autoimmune diseases is further increased by the use of biotherapies. Recommendations to minimize this risk include administering the full complement of vaccines on the standard immunization schedule, as well as the pneumococcal and influenza vaccines. Adults with chronic inflammatory joint disease (IJD) may receive a 13-valent pneumococcal conjugate vaccine, as well as a live attenuated vaccine against recurrent herpes zoster, recently licensed by European regulatory authorities. Live attenuated vaccines can be given only after an interval without immunosuppressant and/or glucocorticoid therapy. The effectiveness of vaccines, as assessed based on titers of protective antibodies, varies across vaccine types and disease-modifying antirheumatic drugs (DMARDs). Thus, methotrexate and rituximab are usually associated with decreased vaccine responses. The risks associated with vaccines are often considerably exaggerated by the media, which serve lobbies opposed to immunizations and make some patients reluctant to accept immunizations. Increasing immunization coverage may diminish the risk of treatment-related infections. A physician visit dedicated specifically to detecting comorbidities in patients with chronic IJD may result in improved immunization coverage. In this review, we discuss immunizations for adults with chronic IJD based on the treatments used, as well as immunization coverage. Many questions remain unanswered and warrant investigation by studies coordinated by the French networks IREIVAC (Innovative clinical research network in vaccinology) and IMIDIATE (Immune-Mediated Inflammatory Disease Alliance for Translational and Clinical Research).

    Osteoarthritis (OA) is the most common form of joint disease. This review aimed to consolidate the current evidence that implicates the inflammatory process in the attenuation of synovial lubrication and joint tissue homeostasis in OA. Moreover, with these findings, we propose some evidence for novel therapeutic strategies for preventing and/or treating this complex disorder. The studies reviewed support that inflammatory mediators participate in the onset and progression of OA after joint injury. The flow of pro-inflammatory cytokines following an acute injury seems to be directly associated with altered lubricating ability in the joint tissue. The latter is associated with reduced level of lubricin, one of the major joint lubricants. Future research should focus on the development of new therapies that attenuate the inflammatory process and restore lubricin synthesis and function. This approach could support joint tribology and synovial lubrication leading to improved joint function and pain relief.

    Recent technological advances in fiber optics, light sources, detectors, and molecular biology have stimulated unprecedented development of optical methods to detect pathological changes in tissues. These methods, collectively termed "optical biopsy," are nondestructive in situ and real-time assays. Optical biopsy techniques as fluorescence spectroscopy, polarized light scattering spectroscopy, optical coherence tomography, confocal reflectance microscopy, and Raman spectroscopy had been extensively used to characterize several pathological tissues. In special, Raman spectroscopy technique had been able to probe several biochemical alterations due to pathology development as change in the DNA, glycogen, phospholipid, non-collagenous proteins. All studies claimed that the optical biopsy methods were able to discriminate normal and malignant tissues. However, few studies had been devoted to the discrimination of very common subtle or early pathological states as inflammatory process, which are always present on, e.g., cancer lesion border. In this work we present a systematic comparison of optical biopsy data on several kinds of lesions were inflammatory infiltrates play the role (breast, cervical, and oral lesion). It will be discussed the essential conditions for the optimization of discrimination among normal and alterated states based on statistical analysis.

    Full Text Available Abstract Introduction The combination of polyethylene glycol (PEGylated interferon (pegylated interferon and ribavirin has been shown to be an effective treatment for chronic hepatitis C virus. In general, common side effects related to this combination therapy are mild and are well tolerated. However, peripheral neuropathy including demyelinating polyneuropathy related to PEG-interferon α2a (pegylated interferon alfa-2a is extremely rare. In the literature, only one case of acute inflammatory demyelinating polyneuropathy related to PEG-interferon α2a has been published previously. Case presentation To the best of our knowledge we present only the second case of acute inflammatory demyelinating polyneuropathy related to PEG-interferon α2a, occurring in a 63-year-old Caucasian man. He developed tingling, numbness, and weakness of his upper and lower extremities with acute neurological deficits after five weeks of a combination therapy with PEG-interferon α2a and ribavirin for chronic hepatitis C virus infection. His clinical course, neurological findings, and his electromyogram results were all consistent with acute inflammatory demyelinating polyneuropathy. Our patient recovered completely after interferon was stopped and symptomatic treatment and a further electromyogram showed a disappearance of neuropathy. Four weeks later, PEG-interferon α2a was reintroduced with a gradually increasing dose without any reappearance of neurological symptoms allowing hepatitis C seroconversion. Conclusions Recognition of this rare yet possible presentation is important for early and accurate diagnosis and treatment. This case report also suggests that the reintroduction of PEGylated interferon in patients who had presented with acute inflammatory demyelinating polyneuropathy related to interferon α may be safe, but this must be confirmed by further studies.

    Full Text Available Aneal Gadgil, Steven R DuncanDivision of Pulmonary, Allergy and Critical Care Medicine, University of Pittsburgh Medical Center, Pittsburgh, PA, USAAbstract: Chronic obstructive pulmonary disease (COPD is the fourth leading cause of death in the US and a major worldwide healthcare problem. The pathophysiologic mechanisms that drive development and progression of this disease are complex and only poorly understood. While tobacco smoking is the primary risk factor, other disease processes also appear to play a role. Components of the innate immune system (eg, macrophages and neutrophils have long been believed to be important in the development of COPD. More recent evidence also suggests involvement of the adaptive immune system in pathogenesis of this disease. Here we will review the literature supporting the participation of T-cells in the development of COPD, and comment on the potential antigenic stimuli that may account for these responses. We will further explore the prospective contributions of T-cell derived mediators that could contribute to the inflammation, alveolar wall destruction, and small airway fibrosis of advanced COPD. A better understanding of these complex immune processes will lead to new insights that could result in improved preventative and/or treatment strategies.Keywords: COPD, T-lymphocytes, adaptive immunity, cytokines

    Oxytocin (OT) is a neuropeptide elaborated by the hypothalamic paraventricular (PVN) and supraoptic (SON) nuclei. Magnocellular OT neurons of these nuclei innervate numerous forebrain regions and release OT into the blood from the posterior pituitary. The PVN also harbors parvocellular OT cells that project to the brainstem and spinal cord, but their function has not been directly assessed. Here, we identified a subset of approximately 30 parvocellular OT neurons, with collateral projections onto magnocellular OT neurons and neurons of deep layers of the spinal cord. Evoked OT release from these OT neurons suppresses nociception and promotes analgesia in an animal model of inflammatory pain. Our findings identify a new population of OT neurons that modulates nociception in a two tier process: (1) directly by release of OT from axons onto sensory spinal cord neurons and inhibiting their activity and (2) indirectly by stimulating OT release from SON neurons into the periphery.

    In Stage II colon cancer, multiple independent studies have shown that a dense intratumoural immune infiltrate (local inflammation) is associated with improved outcomes, while systemic inflammation, measured by various markers, has been associated with poorer outcomes. However, previous studies have not considered the interaction between local and systemic inflammation, nor have they assessed the type of inflammatory response compared with standard clinicopathologic criteria. In order to evaluate the potential clinical utility of inflammatory markers in Stage II colon cancer, we examined local and systemic inflammation in a consecutive series of patients with resected Stage II colon cancer between 2000 and 2010 who were identified from a prospective clinical database. Increased intratumoural chronic inflammatory cell (CIC) density, as assessed by pathologist review of hematoxylin and eosin stained slides, was used to represent local inflammation. Neutrophil-to-lymphocyte ratio (NLR) >5, as calculated from pre-operative full blood counts, was used to represent systemic inflammation. In 396 eligible patients identified, there was a non-significant inverse relationship between local and systemic inflammation. Increased CIC density was significantly associated with improved overall (HR 0.45, p = 0.001) and recurrence-free survival (HR 0.37, p = 0.003). High NLR was significantly associated with poorer overall survival (HR 2.56, p < 0.001). The combination of these markers further stratified prognosis independent of standard high-risk criteria, with a dominant systemic inflammatory response (low CIC/high NLR) associated with the worst outcome (5-year overall survival 55.8%). With further validation this simple, inexpensive combined inflammatory biomarker might assist in patient selection for adjuvant chemotherapy in Stage II colon cancer.

    Electro-peroxone (E-peroxone) treatment of the anti-inflammatory drug ibuprofen aqueous solution was investigated in this study. The E-peroxone process combined conventional ozonation with electrolysis processes, and used a carbon-polytetrafluorethylene cathode to electrochemically generate H2O2 from O2 in the sparged ozone generator effluent (O2 and O3 mixture). The in-situ generated H2O2 then reacted with the sparged O3 to produce aqueous •OH, which can in turn oxidize pollutants effectively in the bulk solution. The E-peroxone process overcomes several intrinsic limitations of conventional ozonation and electrolysis processes for pollutant degradation such as the selective oxidation with O3 and mass transfer limitations of pollutants to the electrodes, and thus significantly enhanced both ibuprofen degradation and total organic carbon (TOC) mineralization. Results show that ibuprofen could be completely degraded much more rapidly in the E-peroxone process (e.g., 5-15 min under all tested reaction conditions) than in ozonation (≥30 min) and electrolysis (several hours) processes. In addition, thanks to the powerful and non-selective oxidation capacity of •OH, toxic intermediates formed during ibuprofen degradation could be completely mineralized in the E-peroxone process. The E-peroxone effluent (2 h) thus exhibited much lower toxicity (5% inhibition of bioluminescence of Vibrio fisheri) than the ozonation and electrolysis effluents (22% and 88% inhibition, respectively). The results of this study indicate that the E-peroxone process may provide a promising technology for pharmaceutical wastewater treatment. PMID:24981746

    Chronic hepatitis is recognized as a worldwide health problem that gradually progresses towards cirrhosis and hepatocellular carcinoma. Despite the large number of experiments using animal models for allergic hepatitis, it is still difficult to produce a picture of chronic hepatitis. Therefore, this study was conducted to introduce an animal model approximating to the mechanism of chronicity in human hepatitis. The study also aimed to examine the hepatoprotective effects of curcumin, silybin phytosome(®) and α-R-lipoic acid against thioacetamide (TAA)-induced chronic hepatitis in rat model. TAA was administered intraperitoneally at a dose of 200 mg/kg three times weekly for 4 weeks. At the end of this period, a group of rats was killed to assess the development of chronic hepatitis in comparison with their respective control group. TAA administration was then discontinued, and the remaining animals were subsequently allocated into four groups. Group 1 was left untreated, whereas groups 2-4 were allowed to receive daily oral doses of curcumin, silybin phytosome(®) or α-R-lipoic acid, respectively, for 7 weeks. Increases in hepatic levels of malondialdehyde associated with TAA administration were inhibited in groups receiving supplements. Furthermore, glutathione depletion, collagen deposition, macrophage activation and nuclear factor κappa-B expression as well as tumour necrosis factor-α and interleukin-6 levels were significantly decreased in response to supplements administration. Serological analysis of liver function and liver histopathological examination reinforced the results. The above evidence collectively indicates that the antioxidant and anti-inflammatory activities of curcumin, silybin phytosome(®) and α-R-lipoic acid may confer therapeutic efficacy against chronic hepatitis.

    Processing of fruits and vegetables affects their phytochemical and nutrient content. Tart cherries are commercially promoted to possess antioxidant and anti-inflammatory activity. However, processing affects their phytochemical content and may affect their related health benefits. The current study compares the in vitro antioxidant capacity and anti-inflammatory cyclooxygenase activity of processed tart cherry (Prunus cerasus) products-cherry juice concentrate, individually quick-frozen cherries, canned cherries, and dried cherries. Cherry products were analyzed for total anthocyanin and proanthocyanidin content and profile. On a per serving basis, total anthocyanins were highest in frozen cherries and total proanthocyanidins were highest in juice concentrate. Total phenolics were highest in juice concentrate. Juice concentrate had the highest oxygen radical absorbance capacity (ORAC) and peroxynitrite radical averting capacity (NORAC). Dried cherries had the highest hydroxyl radical averting capacity (HORAC) and superoxide radical averting capacity (SORAC). Processed tart cherry products compared very favorably to the U.S. Dept. of Agriculture-reported ORAC of other fresh and processed fruits. Inhibition of in vitro inflammatory COX-1 activity was greatest in juice concentrate. In summary, all processed tart cherry products possessed antioxidant and anti-inflammatory activity, but processing differentially affected phytochemical content and in vitro bioactivity. On a per serving basis, juice concentrate was superior to other tart cherry products. PMID:23163942

  1. Persistent oxytetracycline exposure induces an inflammatory process that improves regenerative capacity in zebrafish larvae.

    Francisco Barros-Becker

    Full Text Available BACKGROUND: The excessive use of antibiotics in aquaculture can adversely affect not only the environment, but also fish themselves. In this regard, there is evidence that some antibiotics can activate the immune system and reduce their effectiveness. None of those studies consider in detail the adverse inflammatory effect that the antibiotic remaining in the water may cause to the fish. In this work, we use the zebrafish to analyze quantitatively the effects of persistent exposure to oxytetracycline, the most common antibiotic used in fish farming. METHODOLOGY: We developed a quantitative assay in which we exposed zebrafish larvae to oxytetracycline for a period of 24 to 96 hrs. In order to determinate if the exposure causes any inflammation reaction, we evaluated neutrophils infiltration and quantified their total number analyzing the Tg(mpx:GFP(i114 transgenic line by fluorescence stereoscope, microscope and flow cytometry respectively. On the other hand, we characterized the process at a molecular level by analyzing several immune markers (il-1β, il-10, lysC, mpx, cyp1a at different time points by qPCR. Finally, we evaluated the influence of the inflammation triggered by oxytetracycline on the regeneration capacity in the lateral line. CONCLUSIONS: Our results suggest that after 48 hours of exposure, the oxytetracycline triggered a widespread inflammation process that persisted until 96 hours of exposure. Interestingly, larvae that developed an inflammation process showed an improved regeneration capacity in the mechanosensory system lateral line.

    Mast cells (MCs), which are granulated tissue-resident cells of hematopoietic lineage, contribute to vascular homeostasis, innate/adaptive immunity and wound healing. MCs are, however, best known for their roles in allergic and inflammatory diseases such as anaphylaxis, food allergy, rhinitis, itch, urticaria, atopic dermatitis and asthma. In addition to the high affinity IgE receptor (FcεRI), MCs express numerous G protein coupled receptors (GPCRs), which are the largest group of membrane receptor proteins and are the most common targets of drug therapy. Antimicrobial host defense peptides (HDPs), neuropeptides (NPs), major basic protein (MBP), eosinophil peroxidase (EPO) and many FDA approved peptidergic drugs activate human MCs via a novel GPCR known as MAS-related G protein coupled receptor-X2 (MRGPRX2; formerly known as MrgX2). Unique features of MRGPRX2 that distinguish it from other GPCRs include their presence both on plasma membrane and intracellular sites and their selective expression in MCs. In this article, we review the possible roles of MRGPRX2 on host defense, drug-induced anaphylactoid reactions, neurogenic inflammation, pain, itch and chronic inflammatory diseases such as urticaria and asthma. We propose that HDPs that kill microbes directly and activate MCs via MRGPRX2 could serve as novel GPCR targets to modulate host defense against microbial infection. Furthermore, monoclonal antibodies or small molecule inhibitors of MRGPRX2 could be developed for the treatment of MC-dependent allergic and inflammatory disorders. PMID:27448446

    Interferon- (IFN-) λ1 is regarded as a potent bio-active molecule in innate immunity. However, little is known about its role in chronic spontaneous urticaria (CSU). We therefore investigated expression of IFN-λ1 in CSU, its cellular location, and its influence on inflammatory cell accumulation by using flow cytometry analysis, skin tissue dispersion, immunohistochemical stain, and a mouse peritoneal inflammation model. The results showed that level of IFN-λ1 was 2.0-fold higher in plasma of the patients with CSU than the level in healthy control (HC) subjects. Among leukocytes examined, only CD8+ T cells expressed more IFN-λ1 in CSU blood. Double labeling immunohistochemical staining revealed that IFN-λ1+ inflammatory cells such as mast cells, eosinophils, B cells, neutrophils, and macrophages were mainly located in dermis, whereas epidermis tissue highly expressed IFN-λ1. IFN-λ1 induced a dose-dependent increase in number of eosinophils, lymphocytes, mast cells, macrophages, and neutrophils in the peritoneum of mice at 6 h following injection, which was inhibited by pretreatment of the animals with anti-intercellular adhesion molecule- (ICAM-) 1 and/or anti-L-selectin antibodies. In conclusion, IFN-λ1 is likely to play a role in the pathogenesis of CSU. Blocking IFN-λ1 production may help to reduce the accumulation of inflammatory cells in the involved CSU skin.

    Atherosclerosis is a leading death cause. Endothelial and smooth muscle cells participate in atherogenesis, but it is unclear whether other mesenchymal cells contribute to this process. Bone marrow (BM) nestin(+) cells cooperate with endothelial cells in directing monocyte egress to bloodstream in response to infections. However, it remains unknown whether nestin(+) cells regulate inflammatory cells in chronic inflammatory diseases, such as atherosclerosis. Here, we show that nestin(+) cells direct inflammatory cell migration during chronic inflammation. In Apolipoprotein E (ApoE) knockout mice fed with high-fat diet, BM nestin(+) cells regulate the egress of inflammatory monocytes and neutrophils. In the aorta, nestin(+) stromal cells increase ∼30 times and contribute to the atheroma plaque. Mcp1 deletion in nestin(+) cells-but not in endothelial cells only- increases circulating inflammatory cells, but decreases their aortic infiltration, delaying atheroma plaque formation and aortic valve calcification. Therefore, nestin expression marks cells that regulate inflammatory cell migration during atherosclerosis. PMID:27586429

    Full Text Available The host immune response plays an important role in viral clearance in patients who are chronically infected with hepatitis C virus (HCV and are treated with interferon and ribavirin. Activation of the immune system involves the release of pro and anti-inflammatory molecules that can be measured in plasma samples. The present study aimed to evaluate the association between pretreatment plasma levels of chemokines and soluble tumor necrosis factor receptors (sTNF-R and the virological response in treated patients with chronic hepatitis C infection. Forty-one chronically-infected HCV patients that were being treated with interferon-α (IFN-α plus ribavirin were included in the study. Socio-demographic, clinical and laboratory data were collected and pretreatment plasma levels of chemokine CCL2, CCL3, CCL11, CCL24, chemokine CXCL9, CXCL10, sTNF-R1 and sTNF-R2 were measured. The virological response was assessed at treatment week 12, at the end of treatment and 24 weeks after treatment. Pretreatment CXCL10 levels were significantly higher in patients without an early virological response (EVR or sustained virological response (SVR compared to responders [512.9 pg/mL vs. 179.1 pg/mL (p = 0.011 and 289.9 pg/mL vs. 142.7 pg/mL (p = 0.045, respectively]. The accuracy of CXCL10 as a predictor of the absence of EVR and SVR was 0.79 [confidence interval (CI 95%: 0.59-0.99] and 0.69 (CI 95%: 0.51-0.87, respectively. Pretreatment plasma levels of the other soluble inflammatory markers evaluated were not associated with a treatment response. Pretreatment CXCL10 levels were predictive of both EVR and SVR to IFN-α and ribavirin and may be useful in the evaluation of candidates for therapy.

    Full Text Available There are a limited number of studies correlating the different stages of dendritic cells (DC maturation with cytokines in individuals presented chronic periodontitis (CP. The aim of the study was to evaluate the correlation among the expression of IL-2, IL-10, IL-4, IL-6, IFN-γ, TNF-α, and IL-17A with the presence of DC and mild-moderate or advanced CP. Gingival samples were obtained from 24 individuals with CP and six samples of normal mucosa (NM overlapping third molar for controls of the levels of cytokines. Periodontal examination was performed. Immunohistochemical staining was carried out, revealing CD1a+ immature, Fator XIIIa+ immature, and CD83+ mature DCs. The inflammatory infiltrate was counted, and the cytokines were measured by flow cytometry. Densities of DCs and inflammatory infiltrate, cytokines, subtypes of CP, and clinical periodontal parameters were correlated and compared. IL-6 expression was correlated positively with the increased numbers of CD1a+ immature DCs. Levels of IL-2, TNF-α, IFN-γ, IL-10, and IL-17A were increased when compared with NM. The percentage of sites with clinical attachment level (CAL>3 were positively correlated with densities of inflammatory infiltrate and negatively correlated with densities of immature DCs. IL-6 can contribute to the increase of the immature DCs in the CP. Higher levels of IL-2, TNF-α, IFN-γ, IL-10, and IL-17A cytokines were observed in CP. Higher densities of inflammatory infiltrate as well as lower densities of immature DCs can result in a more severe degree of human CP.

    Temporomandibular disorders (TMDs) are mostly inflammatory conditions widespread in the population. Previous studies have shown positive effects of either laser or light-emitting diode (LED) phototherapies on treating TMDs, but their action and mechanism in the inflammatory infiltrate of the temporomandibular joint are still poorly understood. The aim of this study was to assess, through histological analysis, the effectiveness of using laser light (λ 780 nm, 70 mW, continous wave (CW), 10 J) and LED (λ 850 ± 10 nm, 100 mW, CW, 10 J) on the inflammation of the temporomandibular joint of rats induced by carrageenan. Forty-five animals were divided into three groups with five animals each according to the experimental times of 2, 3, and 7 days: inflammation, inflammation+laser phototherapy, and inflammation+LED phototherapy. The first irradiation was performed 24 h after induction with an interval of 48 h between sessions. After animal death, specimens were processed and stained with hematoxylin-eosin (HE) and picrosirius. Then, the samples were examined histologically. Data were statistically analyzed. The inflammation group showed mild to moderate chronic inflammatory infiltrate between bone trabecules of the condyle. Over the time course of the study in the laser group, the region of the condyle presented mild chronic inflammation and intense vascularization. In the LED group, the condyle showed aspects of normality and absence of inflammation in some specimens. In all the time points, the laser-irradiated groups showed greater amount of collagen deposition in the condyle (p = 0.04) and in the disc (p = 0.03) when compared to the inflammation and LED groups, respectively. Laser- and LED-treated groups demonstrate a smaller number of layers of the synovial membrane when compared to the non-irradiated groups. It was concluded that, in general, laser and LED phototherapies resulted in a reduction of inflammatory infiltrate in the

    AIM: To investigate the effect of a new oral preparation, highly concentrated in fish cartilage, in a group of inflammatory bowel diseases (IBD) patients with chronic iron deficient anemia.METHODS: In an open label pilot study, we supplemented a group of 25 patients (11 with Crohn's disease and 14 with ulcerative colitis) in stable clinical conditions and chronic anemia with a food supplement which does not contain iron but contains a standardized fraction of fish cartilage glycosaminoglycans and a mixture of antioxidants (Captafer Medestea, Turin, Italy). Patients received 500 mg, twice a day during meals, for at least 4 mo. Patients were suggested to maintain their alimentary habit. At time 0 and after 2 and 4 mo, emocrome, sideremia and ferritin were examined. Paired data were analyzed with Student's t test.RESULTS: Three patients relapsed during the study (2 in the 3rt mo, 1 in the 4th mo), two patients were lost to follow up and two patients dropped out (1 for orticaria, 1 for gastric burning). Of the remaining 18 patients, levels of serum iron started to rapidly increase within the 2nd mo of treatment, P < 0.05), whereas serum ferritin and hemoglobin needed a longer period to significantly improve their serum levels (mo 4) P < 0.05. The product was safe, easy to administer and well tolerated by patients.CONCLUSION: These data suggest a potential new treatment for IBD patients with iron deficiency chronic anemia and warrant further larger controlled studies.

    Full Text Available Abstract Background Equine laminitis is a devastating disease that causes severe pain in afflicted horses and places a major economic burden on the horse industry. In acute laminitis, the disintegration of the dermal-epidermal junction can cause the third phalanx to detach from the hoof wall, leaving the horse unable to bear weight on the affected limbs. Horses that survive the acute phase transition into a chronic form of laminitis, which is often termed “founder”. Some evidence suggests that chronic laminar inflammation might be associated with alterations in the endocrine and immune systems. We investigated this broad hypothesis by using DIGE to assess global differences in the plasma proteome between horses with chronic laminitis and controls. Results We identified 16 differentially expressed proteins; the majority of these were involved in the interrelated coagulation, clotting, and kininogen cascades. Clinical testing of functional coagulation parameters in foundered horses revealed a slight delay in prothrombin (PT clotting time, although most other indices were within normal ranges. Upregulation of the intestinal apolipoprotein APOA-IV in horses with chronic laminitis was confirmed by western blot. Conclusions Our results support the hypothesis that localized laminar inflammation may be linked to systemic alterations in immune regulation, particularly in the gastrointestinal system. Gastrointestinal inflammation has been implicated in the development of acute laminitis but has not previously been associated with chronic laminitis.

    Proteases and antiproteases have multiple important roles both in normal homeostasis and during inflammation. Antiprotease molecules may have developed in a parallel network, consisting of "alarm" and "systemic" inhibitors. Their primary function was thought until recently to mainly prevent the potential injurious effects of excess release of proteolytic enzymes, such as neutrophil elastase (NE), from inflammatory cells. However, recently, new potential roles have been ascribed to these antiproteases. We will review "canonical" and new "noncanonical" functions for these molecules, and more particularly, those pertaining to their role in innate and adaptive immunity (antibacterial activity and biasing of the adaptive immune response).

    We simultaneously investigated the genetic landscape of ankylosing spondylitis, Crohn's disease, psoriasis, primary sclerosing cholangitis and ulcerative colitis to investigate pleiotropy and the relationship between these clinically related diseases. Using high-density genotype data from more than 86,000 individuals of European ancestry, we identified 244 independent multidisease signals, including 27 new genome-wide significant susceptibility loci and 3 unreported shared risk loci. Complex pleiotropy was supported when contrasting multidisease signals with expression data sets from human, rat and mouse together with epigenetic and expressed enhancer profiles. The comorbidities among the five immune diseases were best explained by biological pleiotropy rather than heterogeneity (a subgroup of cases genetically identical to those with another disease, possibly owing to diagnostic misclassification, molecular subtypes or excessive comorbidity). In particular, the strong comorbidity between primary sclerosing cholangitis and inflammatory bowel disease is likely the result of a unique disease, which is genetically distinct from classical inflammatory bowel disease phenotypes.

    Negative affective states such as depression are associated with premature mortality and increased risk of coronary heart disease, type 2 diabetes, and disability. It has been suggested that positive affective states are protective, but the pathways through which such effects might be mediated are poorly understood. Here we show that positive affect in middle-aged men and women is associated with reduced neuroendocrine, inflammatory, and cardiovascular activity. Positive affect was assessed by aggregating momentary experience samples of happiness over a working day and was inversely related to cortisol output over the day, independently of age, gender, socioeconomic position, body mass, and smoking. Similar patterns were observed on a leisure day. Happiness was also inversely related to heart rate assessed by using ambulatory monitoring methods over the day. Participants underwent mental stress testing in the laboratory, where plasma fibrinogen stress responses were smaller in happier individuals. These effects were independent of psychological distress, supporting the notion that positive well-being is directly related to health-relevant biological processes. PMID:15840727

    The study of plants used in traditional medicine has drawn the attention of researchers as an alternative in the development of new therapeutics agents, such as the American Solanaceae Physalis peruviana, which has significant anti-inflammatory activity. The Physalis peruviana anti-inflammatory effect of ethanol or ether calyces extracts on the phagocytic process was assessed by using an in vitro phagocytosis model (Leishmania panamensis infection to murine macrophages). The Physalis peruviana extracts do not inhibit microorganism internalization and have no parasiticide effect. Most ET and EP extracts negatively affected the parasite's invasion of macrophages (Infected cells increased.). This observation might result from a down-regulation of the macrophage's microbicide ability associated with a selective reduction of proinflammatory cytokines levels. Physalis peruviana's anti-inflammatory activity described in this model is related to an immunomodulatory effect exerted on macrophages infected, which directly or indirectly "blocks" their ability to secrete soluble proinflammatory mediators.

  17. PET molecular imaging of peripheral and central inflammatory processes targeting the TSPO 18 kDa

    International Nuclear Information System (INIS)

    The purpose of this study was to determine the in vivo potential of the TSPO 18 kDa as a bio-marker of inflammation, with the use of its radioligand [18F]DPA-714, to non-invasively quantify the inflammatory state within the scope of various pathologies. Multiple animal models of various inflammatory diseases, to include: inflammatory bowel disease, neuro-inflammation, and septic shock, were developed and put in place by adapted measures. The animals well-being and the subsequent inflammation was evaluated. The inflammatory state was measured using quantitative PET imaging with the TSPO radioligand [18F]DPA-714 and correlated to the expression of conventional inflammatory markers using microscopy. Based on the observed data, we were able to distinguish control groups from treated groups when using [18F]DPA-714. This TSPO radioligand permitted us to quantify the inflammatory level and to observe evolutionary changes in the inflammatory state of the disease in multiple models. The PET results, using the [18F]DPA-714 signal was correlated with an increased TSPO expression at cellular level. Results indicate that [18F]DPA-714 is a suitable tracer for studying inflammation of multiple diseases. [18F]DPA-714 could be a good molecular probe to non-invasively evaluate the level and localization of inflammation. Moreover, in vivo imaging using this TSPO ligand is potentially a powerful tool to stage and certainly to follow the evolution and therapeutic efficiency at molecular level in inflammatory diseases.

    We report the case of a 14-year-old girl who developed postural orthostatic tachycardia syndrome (POTS) with chronic fatigue 2 months following Gardasil vaccination. The patient suffered from persistent headaches, dizziness, recurrent syncope, poor motor coordination, weakness, fatigue, myalgias, numbness, tachycardia, dyspnea, visual disturbances, phonophobia, cognitive impairment, insomnia, gastrointestinal disturbances, and a weight loss of 20 pounds. The psychiatric evaluation ruled out the possibility that her symptoms were psychogenic or related to anxiety disorders. Furthermore, the patient tested positive for ANA (1:1280), lupus anticoagulant, and antiphospholipid. On clinical examination she presented livedo reticularis and was diagnosed with Raynaud's syndrome. This case fulfills the criteria for the autoimmune/auto-inflammatory syndrome induced by adjuvants (ASIA). Because human papillomavirus vaccination is universally recommended to teenagers and because POTS frequently results in long-term disabilities (as was the case in our patient), a thorough follow-up of patients who present with relevant complaints after vaccination is strongly recommended.

    HLA associations are found to differ with the gender of the patient in some autoimmune diseases. Here we have investigated whether there are gender-related HLA associations in Guillain-Barré syndrome (GBS) and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), both of which occur more frequently in male patients than in females. In GBS, no particular HLA associations were noted, except for a slight negative association in both males and females for carriage of HLA-DR5. In CIDP, the gene frequency and the frequency of individuals positive for HLA-DR2 were greater in female patients than female controls, although this was statistically significant only for the gene frequency. Furthermore more female CIDP patients were homozygous for DR2, than male CIDP patients, or male or female controls and patients with GBS. This suggests that sex-related factors may interact with the risk associated with carriage of HLA-DR2 for development of CIDP.

    Elevated anti-Epstein-Barr virus (EBV) antibody levels are present in serum of Multiple sclerosis (MS) patients but literature lacks of studies comparing anti-EBV antibody levels between MS and other neurological diseases. We evaluate anti-VCA IgG and IgM, anti-EBNA1 IgG, anti-Cytomegalovirus IgG and IgM titres in serum and cerebrospinal fluid (CSF) of 267 MS, 50 Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP) and 88 Amyotrophic Lateral Sclerosis (ALS) patients. We found increased titres of anti-EBV-IgG in serum and CSF of MS subjects as compared to CIDP and ALS patients thus providing additional evidence for a possible involvement of EBV in MS.

    Full Text Available Background: The Chronic Inflammatory Periodontal Disease is related with multiple risk factors. Those patients with human immunodeficiency virus have higher risk of presenting this disease and it is usually more serious in these cases. Objective: To describe the prevalence of Chronic Inflammatory Periodontal Disease in patients with HIV. Methods: Descriptive, observational, cross-sectional study including patients with HIV in Sancti Spiritus province. The occurrence of the disease was determined after the Periodontics Cuban Standards, and oral hygiene was assessed through the simplified oral hygiene index. Other variables were measured, such as smoking habits, T CD4+ lymphocyte counting and virus load. The independent association of each risk factor with the disease was determined through a logistic regression model. Results: The 56, 5 % of the 154 patients presented Chronic Inflammatory Periodontal Disease; 60 (39.0% gingivitis and 27 (17,5% periodontitis. Gingivitis was associated with poor oral hygiene (OR: 3,71 and periodontitis with smoking habit (OR: 5,20. The severe forms of periodontitis occurred mainly in patients with lymphocyte counting lower than 500 cells/mm3 . Conclusions: The prevalence of Chronic Inflammatory Periodontal Disease in patients with HIV in Sancti Spiritus province is linked to known risk factors such as smoking habits and oral hygiene.Fundamento: La enfermedad periodontal inflamatoria crónica es un trastorno relacionado con diversidad de factores de riesgo.

    2001-07-01

    Full Text Available Abstract The 97th American Thoracic Society meeting proved to be an excellent meeting, providing a wealth of new information on inflammatory diseases of the airways. Once again there appeared to be an increased emphasis on chronic obstructive pulmonary disease (COPD with most of the major drug companies concentrating a large part of their efforts in this field. An assessment of the new British Thoracic Society guidelines, which are designed to promote better management of COPD, was also presented at the meeting. Potential new treatments for inflammatory diseases of the airways including COPD were described, ranging from phase III trial data with GlaxoSmithKline's PDE4 inhibitor, Cilomilast (Ariflo® to the development of AstraZeneca's novel dual dopamine D2-receptor/β2-adrenoreceptor agonist, Viozan™. Of particular interest was Byk Gulden's Ciclesonide, a new corticosteroid with equivalent efficacy to the market leaders but with an improved safety profile. The same company also presented data on their PDE4 inhibitor, Roflumilast, which is now in phase II/III. Bayer presented data on their PDE4 inhibitor, BAY 19-8004, in a smoking animal model and claimed greater anti-inflammatory efficacy than with a steroid. Asta Medica (now known as Elbion also described a new potent PDE4 inhibitor, AWD 12-281, with anti-inflammatory activity. In the bronchodilator field, an analysis of data from a one-year trial with Boehringer Ingelheim's Tiotropium revealed a possible improvement in lung function in COPD patients; this needs to be confirmed in a specifically designed study. Inhibitors of p38 (c-Jun NH2-terminal kinase and syk kinase were also discussed as anti-inflammatory agents with potential in the treatment of COPD and asthma. GlaxoSmithKline's p38 kinase inhibitor, SB 239063, appeared to be the most advanced of these with clinical data expected in two to three years. Lyn kinase was also discussed as a novel target for inflammatory airway diseases.

    Full Text Available A leading role of phagocytes in prevention of M. tuberculosis infection is well established. Various clinical variants of tubercular inflammatory process necessitate further studies of functional and metabolic features of blood phagocytes in the patients with different forms of lung tuberculosis, being the main goal of this study. We have observed a total of 124 persons including 25 healthy subjects, and 99 patients with tuberculosis who manifested with different types of tubercular inflammatory process, i.e., 31 patients had a limited specific process (tuberculoma; in 44 patients, an infiltrative lung tuberculosis was diagnosed, and 24 patients had fibro-cavernous tuberculosis of lungs. We studied activation markers of neutrophils and monocytes (phagotest, burst-test, CD11b+, CD11c+, HLA-DR-Ag, as well as main indicators of cellular immunity (CD45+CD3+, CD45+CD19+, CD45+CD3- CD16+56+. Statistical evaluation was carried out in the «Microsoft Office Excel 2007» and «Statistica for Windows v. 6.1» environment.A considerable decrease in proportion of superoxide anion-producing monocytes was found in 10% of the patients with fibro-cavernous tuberculosis as compared to the patients with tuberculoma and infiltrative tuberculosis. Similarly, the fibro-cavernous tuberculosis was characterized by higher expression of adhesion markers, e.g., CD11b, by 49%, and CD11c, by 73.5%, when compared with the two other groups of patients. A considerable decrease of absorbing granulocyte function was found in the patients with active forms of tuberculosis, as compared with limited clinical forms (tuberculoma. Fibro-cavernous tuberculosis was associated with increased absolute numbers of granulocyte that produce both superoxide anion, and express surface CD11b+ and CD11c+. We have revealed a relative decrease in lymphocyte quantities in the patients from tuberculoma which corresponded to increased granulocyte quantities of granulocytes and monocytes in the

Such effects relate to inflammation, immune responses, wound healing, and prevention and treatment of chronic inflammatory and autoimmune diseases. The purpose of this report is two-fold: to 1 inform researchers about what appears to be a new perspective to the study of inflammation, and 2 alert researchers that the length of time and degree (resistance to ground of grounding of experimental animals is an important but usually overlooked factor that can influence outcomes of studies of inflammation, wound healing, and tumorigenesis. Specifically, grounding an organism produces measurable differences in the concentrations of white blood cells, cytokines, and other molecules involved in the inflammatory response. We present several hypotheses to explain observed effects, based on current research results and our understanding of the electronic aspects of cell and tissue physiology, cell biology, biophysics, and biochemistry. An experimental injury to muscles, known as delayed onset muscle soreness, has been used to monitor the immune response under grounded versus ungrounded conditions. Grounding reduces pain and alters the numbers of circulating neutrophils and lymphocytes, and also affects various circulating chemical factors related to inflammation.

    We report firsthand on innovative developments in non-invasive, biophotonic techniques for a wide range of diagnostic, imaging and treatment options, including the recognition and quantification of cancerous, pre-cancerous cells and chronic inflammatory conditions. These techniques have benefited from the ability to target the affected site by both monochromatic light and broad multiple wavelength spectra. The employment of such wavelength or color-specific properties embraces the fluorescence stimulation of various photosensitizing drugs, and the instigation and detection of identified fluorescence signatures attendant upon laser induced fluorescence (LIF) phenomena as transmitted and propagated by precancerous, cancerous and normal tissue. In terms of tumor imaging and therapeutic and treatment options, we have exploited the abilities of various wavelengths to penetrate to different depths, through different types of tissues, and have explored quantifiable absorption and reflection characteristics upon which diagnostic assumptions can be reliably based and formulated. These biophotonic-based diagnostic, sensing and imaging techniques have also benefited from, and have been further enhanced by, the integrated ability to provide various power levels to be employed at various stages in the procedure. Applications are myriad, including non-invasive, non destructive diagnosis of in vivo cell characteristics and functions; light-based tissue analysis; real-time monitoring and mapping of brain function and of tumor growth; real time monitoring of the surgical completeness of tumor removal during laser-imaged/guided brain resection; diagnostic procedures based on fluorescence life-time monitoring, the monitoring of chronic inflammatory conditions (including rheumatoid arthritis), and continuous blood glucose monitoring in the control of diabetes.

    We report an autopsy case of a 74-year-old man with late onset Charcot-Marie-Tooth disease type 1A (CMT1A) diagnosed by genetic screening, later associated with amyotrophic lateral sclerosis (ALS). At the age of 70 years, the patient was admitted to our hospital because of progressive weakness and dysesthesia in the right upper limb. In the early stages of the illness, he was diagnosed with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), and transient improvement was achieved with intravenous immunoglobulin. However, the symptoms progressively worsened and became refractory. Gene analysis revealed PMP22 gene duplication, which confirmed CMT1A. On sural nerve biopsy, severe demyelinating neuropathy and abundant onion-bulb formations with endoneurial infiltration of inflammatory cells were observed. Thereafter, pseudo-bulbar palsy and respiratory muscle weakness developed insidiously and progressed rapidly along with muscle weakness in the limbs and trunk. The patient died about four years after the onset of this disease. Postmortem examination showed moderate neuronal cell loss, Bunina bodies, and TDP-43-positive inclusions in the anterior horn cells. The spinal cord revealed axonal loss and extensive macrophage permeation in the corticospinal tracts. On the basis of these findings, the final neuropathological diagnosis was ALS. This is the first report of an autopsy case of CMT1A complicated with ALS. We here discuss the significant clinical and neuropathological findings of this case.

    A randomized trial (ICE trial) in chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) demonstrated significantly more improvement with intravenous immunoglobulin (Gamunex(®), Talecris Biotherapeutics, Inc., Research Triangle Park, NC) than placebo. To understand the relationship between CIDP impairments, activity and participation restrictions, and quality of life (QoL) in this trial, we investigated the association between scales representing these outcome levels. Gamunex or placebo was given every 3 weeks for up to 24 weeks to 117 patients in an initial treatment period after which treatment failures were crossed over (alternative treatment). We assessed impairments, activity and participation, and SF-36 component mental (MCS) and physical summaries (PCS). Regression analyses of baseline data were performed (all subjects) and change from baseline to endpoint (Gamunex-treated group only) to determine correlations between outcomes. Grip strength, medical research council (MRC) sum score, and inflammatory neuropathy cause and treatment (INCAT) sensory sum score were the strongest explanatory variables of disability (at baseline: r(2) = 0.46; change from baseline: r(2) = 0.66). Only up to half of the variance in QoL scores (PCS at baseline: r(2) = 0.30; change from baseline: r(2) = 0.41; MCS: at baseline: r(2) = 0.10; change from baseline: r(2) = 0.24) was explained by impairment and activity and participation measures. Future studies are required to elucidate the impact of CIDP on disability and QoL changes, because the obtained correlations provide only partial explanation.

  9. Hyper-activated pro-inflammatory CD16 monocytes correlate with the severity of liver injury and fibrosis in patients with chronic hepatitis B.

    Directory of Open Access Journals (Sweden)

    Ji-Yuan Zhang

    Full Text Available BACKGROUND: Extensive mononuclear cell infiltration is strongly correlated with liver damage in patients with chronic hepatitis B virus (CHB infection. Macrophages and infiltrating monocytes also participate in the development of liver damage and fibrosis in animal models. However, little is known regarding the immunopathogenic role of peripheral blood monocytes and intrahepatic macrophages. METHODOLOGY/PRINCIPAL FINDINGS: The frequencies, phenotypes, and functions of peripheral blood and intrahepatic monocyte/macrophage subsets were analyzed in 110 HBeAg positive CHB patients, including 32 immune tolerant (IT carriers and 78 immune activated (IA patients. Liver biopsies from 20 IA patients undergoing diagnosis were collected for immunohistochemical analysis. IA patients displayed significant increases in peripheral blood monocytes and intrahepatic macrophages as well as CD16(+ subsets, which were closely associated with serum alanine aminotransferase (ALT levels and the liver histological activity index (HAI scores. In addition, the increased CD16(+ monocytes/macrophages expressed higher levels of the activation marker HLA-DR compared with CD16(- monocytes/macrophages. Furthermore, peripheral blood CD16(+ monocytes preferentially released inflammatory cytokines and hold higher potency in inducing the expansion of Th17 cells. Of note, hepatic neutrophils also positively correlated with HAI scores. CONCLUSIONS: These distinct properties of monocyte/macrophage subpopulations participate in fostering the inflammatory microenvironment and liver damage in CHB patients and further represent a collaborative scenario among different cell types contributing to the pathogenesis of HBV-induced liver disease.

    Abstract Background Equine laminitis is a devastating disease that causes severe pain in afflicted horses and places a major economic burden on the horse industry. In acute laminitis, the disintegration of the dermal-epidermal junction can cause the third phalanx to detach from the hoof wall, leaving the horse unable to bear weight on the affected limbs. Horses that survive the acute phase transition into a chronic form of laminitis, which is often termed “founder”. Some evidence suggests tha...

    We simultaneously investigated the genetic landscape of ankylosing spondylitis, Crohn's disease, psoriasis, primary sclerosing cholangitis and ulcerative colitis to investigate pleiotropy and the relationship between these clinically related diseases. Using high-density genotype data from more than 86,000 individuals of European-ancestry we identified 244 independent multi-disease signals including 27 novel genome-wide significant susceptibility loci and 3 unreported shared risk loci. Complex pleiotropy was supported when contrasting multi-disease signals with expression data sets from human, rat and mouse, and epigenetic and expressed enhancer profiles. The comorbidities among the five immune diseases were best explained by biological pleiotropy rather than heterogeneity (a subgroup of cases that is genetically identical to another disease, possibly due to diagnostic misclassification, molecular subtypes, or excessive comorbidity). In particular, the strong comorbidity between primary sclerosing cholangitis and inflammatory bowel disease is likely the result of a unique disease, which is genetically distinct from classical inflammatory bowel disease phenotypes.

    Full Text Available Background. Long-term home noninvasive mechanical ventilation (NIV is beneficial in COPD but its impact on inflammation is unknown. We assessed the hypothesis that NIV modulates systemic and pulmonary inflammatory biomarkers in stable COPD. Methods. Among 610 patients referred for NIV, we shortlisted those undergoing NIV versus oxygen therapy alone, excluding subjects with comorbidities or non-COPD conditions. Sputum and blood samples were collected after 3 months of clinical stability and analyzed for levels of human neutrophil peptides (HNP, interleukin-6 (IL-6, interleukin-10 (IL-10, and tumor necrosis factor-alpha (TNF-alpha. Patients underwent a two-year follow-up. Unadjusted, propensity-matched, and pH-stratified analyses were performed. Results. Ninety-three patients were included (48 NIV, 45 oxygen, with analogous baseline features. Sputum analysis showed similar HNP, IL-6, IL-10, and TNF-alpha levels (P>0.5. Conversely, NIV group exhibited higher HNP and IL-6 systemic levels (P<0.001 and lower IL-10 concentrations (P<0.001. Subjects undergoing NIV had a significant reduction of rehospitalizations during follow-up compared to oxygen group (P=0.005. These findings were confirmed after propensity matching and pH stratification. Conclusions. These findings challenge prior paradigms based on the assumption that pulmonary inflammation is per se detrimental. NIV beneficial impact on lung mechanics may overcome the potential unfavorable effects of an increased inflammatory state.

    Chronic and recurrent respiratory tract disorders are a frequent problem in general practice. The purpose of the study was to investigate the role of hypersensitivity to house dust mites in respiratory tract diseases in general practice patients. We tried to assess the influence of determined risk factors exposure on development of respiratory tract allergy. Patients from family practitioners surgeries with chronic or recurrent respiratory tract symptoms who had no diagnosis of allergy were recruited to the study (n = 89). All patients responded to a questionnaire focused on history of symptoms, atopic conditions in family and exposure to determined environmental factors like dwelling conditions, obstetrician history, diet in the first year of life. All patients underwent skin prick test with common inhalant allergens. Families of the patients were asked to participate in the study. Families who agreed to take part also responded to the questionnaire and underwent skin tests. In patients and their families blood samples were taken to determine total IgE and specific IgE antibodies to mites allergens. Dust samples were collected by vacuuming of patients' bedroom carpets and mattresses to determine house dust mites allergens concentration. Data on 30 complete patients family sets of their brotherhood, mother and father were collected. Total and specific serum IgE antibodies were determined by disc enzyme-immunoassay (Analco). Mites allergens concentration in dust was measured by simple Acarex strip test (Nexter). The results of the assays (positive skin tests and/or elevated levels of specific IgE) showed allergy to house dust mites in 24 of 89 study patients from general practitioners surgeries (27%). The prevalence of chronic rhinitis, recurrent bronchitis, chronic or recurrent cough, wheezing, dyspnoea was higher in allergic than in nonallergic subjects. Patients with the diagnosis of allergy to house dust mites had usually worse dwelling conditions. Especially

    Full Text Available Background. Asthma is a disorder characterized by a predominance of Th2 cells and eosinophilic inflammation. Suppressors of cytokine signaling (SOCS proteins act as negative regulators of cytokine signaling. In particular, SOCS1 and SOCS3 play an important role in immune response by controlling the balance between Th1 and Th2 cells. In a previous study, we demonstrated that treatment of chronic asthmatic mice with gene therapy using plasmid encoding galectin-3 (Gal-3 led to an improvement in Th2 allergic inflammation. Methods. Using a microarray approach, this study endeavored to evaluate the changes produced by therapeutic Gal-3 delivered by gene therapy in a well-characterized mouse model of chronic airway inflammation. Results were confirmed by real-time RT-PCR, Western blot and immunohistochemical analysis. Results. We identify a set of genes involved in different pathways whose expression is coordinately decreased/increased in mice treated with Gal-3 gene therapy. We report a correlation between Gal-3 treatment and inhibition of SOCS1 and SOCS3 expression in lungs. Conclusion. These results suggest that negative regulation of SOCS1 and 3 following Gal-3 treatment could be a valuable therapeutic approach in allergic disease.

    Full Text Available Any link between pancreatic carcinoma and chronic pancreatitis could reflect the malignant potential of a chronic inflammatory process. Four patients with ductal adenocarcinomas had a long history of pancreatic pain (median duration 5 years and showed clearcut evidence of chronic pancreatitis “downstream” of the tumour. Four were alcoholics and two heavy smokers. These four cases arose within a surgical series of approximately 250 patients with chronic pancreatitis, giving an incidence of 1.6 per cent. The incidence and anatomical distribution of carcinoma and chronic pancreatitis could possibly be consistent with a casual relationship.

    Full Text Available Ulcerative colitis (colitis ulcerosa is a non-specific inflammatory bowel disease of unknown etiology. Thesymptoms which are observed in the course of ulcerative colitis are: an increase in the number of leukocytes andblood platelets, an increase in the concentration of IL-6 and anemia. Blood platelets are the key element, linkingthe processes of hemostasis, inflammation and the repair of damaged tissues. Activation of blood platelets is connectedwith changes in their shape and the occurrence of the reaction of release. P-selectin appears on the surfacesof activated blood platelets and the concentration level of soluble P-selectin increases in the blood plasma. The aimof this study was to define whether the increased number of blood platelets in patients with ulcerative colitisaccompanies changes in their activation and morphology. A total of 16 subjects with ulcerative colitis and 32healthy subjects were studied. Mean platelet count, morphological parameters of platelets and MPC were measuredusing an ADVIA 120 hematology analyzer. Concentrations of sP-selectin and IL-6 in serum were marked byimmunoassay (ELISA. MPC, concentration of sP-selectin and IL-6 were significantly higher in subjects with ulcerativecolitis compared to those in the healthy group. There was a decrease of MPV in patients with ulcerativecolitis, which is statistically significant. Chronic inflammation in patients with ulcerative colitis causes an increase inthe number of blood platelets, a change in their morphology and activation. Decreased MPV value reflects activationand the role blood platelets play in the inflammatory process of the mucous membrane of the colon. A highconcentration of sP-selectin, which is a marker of blood platelet activation, demonstrates their part in the inflammatoryprocess. The increase in the concentration of sP-selectin correlated positively with the increase in concentrationof IL-6. This is why it may be a useful marker of the activity of

    Full Text Available Abstract Background Chronic kidney disease progression has been linked to pro-inflammatory cytokines and markers of inflammation. These markers are also elevated in end-stage renal disease (ESRD, which constitutes a serious public health problem. Objective To investigate whether single nucleotide polymorphisms (SNPs located in genes related to immune and inflammatory processes, could be associated with ESRD development. Design and methods A retrospective case-control study was carried out on 276 patients with ESRD and 288 control subjects. Forty-eight SNPs were genotyped via SNPlex platform. Logistic regression was used to assess the relationship between each sigle polymorphism and the development of ESRD. Results Four polymorphisms showed association with ESRD: rs1801275 in the interleukin 4 receptor (IL4R gene (OR: 0.66 (95%CI = 0.46-0.95; p = 0.025; overdominant model, rs4586 in chemokine (C-C motif ligand 2 (CCL2 gene (OR: 0.70 (95%CI = 0.54-0.90; p = 0.005; additive model, rs301640 located in an intergenic binding site for signal transducer and activator of transcription 4 (STAT4 (OR: 1.82 (95%CI = 1.17-2.83; p = 0.006; additive model and rs7830 in the nitric oxide synthase 3 (NOS3 gene (OR: 1.31 (95%CI = 1.01-1.71; p = 0.043; additive model. After adjusting for multiple testing, results lost significance. Conclusion Our preliminary data suggest that four genetic polymorphisms located in genes related to inflammation and immune processes could help to predict the risk of developing ESRD.

    Full Text Available Abstract Background Imbalances in the regulation of pro-inflammatory cytokines have been increasingly correlated with a number of severe and prevalent neurodevelopmental disorders, including autism spectrum disorder, schizophrenia and Down syndrome. Although several studies have shown that cytokines have potent effects on neural function, their role in neural development is still poorly understood. In this study, we investigated the link between abnormal cytokine levels and neural development using the Xenopus laevis tadpole visual system, a model frequently used to examine the anatomical and functional development of neural circuits. Results Using a test for a visually guided behavior that requires normal visual system development, we examined the long-term effects of prolonged developmental exposure to three pro-inflammatory cytokines with known neural functions: interleukin (IL-1β, IL-6 and tumor necrosis factor (TNF-α. We found that all cytokines affected the development of normal visually guided behavior. Neuroanatomical imaging of the visual projection showed that none of the cytokines caused any gross abnormalities in the anatomical organization of this projection, suggesting that they may be acting at the level of neuronal microcircuits. We further tested the effects of TNF-α on the electrophysiological properties of the retinotectal circuit and found that long-term developmental exposure to TNF-α resulted in enhanced spontaneous excitatory synaptic transmission in tectal neurons, increased AMPA/NMDA ratios of retinotectal synapses, and a decrease in the number of immature synapses containing only NMDA receptors, consistent with premature maturation and stabilization of these synapses. Local interconnectivity within the tectum also appeared to remain widespread, as shown by increased recurrent polysynaptic activity, and was similar to what is seen in more immature, less refined tectal circuits. TNF-α treatment also enhanced the

    Full Text Available This study evaluated the antilipogenic and anti-inflammatory effects of Codonopsis lanceolata (C. lanceolata root extract in mice with alcohol-induced fatty liver and elucidated its underlying molecular mechanisms. Ethanol was introduced into the liquid diet by mixing it with distilled water at 5% (wt/v, providing 36% of the energy, for nine weeks. Among the three different fractions prepared from the C. lanceolata root, the C. lanceolata methanol extract (CME exhibited the most remarkable attenuation of alcohol-induced fatty liver with respect to various parameters such as hepatic free fatty acid concentration, body weight loss, and hepatic accumulations of triglyceride and cholesterol. The hepatic gene and protein expression levels were analysed via RT-PCR and Western blotting, respectively. CME feeding significantly restored the ethanol-induced downregulation of the adiponectin receptor (adipoR 1 and of adipoR2, along with their downstream molecules. Furthermore, the study data showed that CME feeding dramatically reversed ethanol-induced hepatic upregulation of toll-like receptor- (TLR- mediated signaling cascade molecules. These results indicate that the beneficial effects of CME against alcoholic fatty livers of mice appear to be with adenosine- and adiponectin-mediated regulation of hepatic steatosis and TLR-mediated modulation of hepatic proinflammatory responses.

    Objective To investigate the role of CXC chemokine receptor 3(CXCR3 ) in bleomycin-induced lung injury by using CXCR3 gene deficient mice.Methods Sex-, age-, and weight-matched C57BL/6 CXCR3 gene knockout mice and C57BL/6 wide type mice were challenged by injection of bleomycin via trachea. Lung tissue was stained with HE method. Airway resistance was measured. Bronchoalveolar lavage (BAL) was performed using phosphate buffered saline twice, cell number and differentials were counted by Diff-Qnick staining. Interleukin(IL)-4, IL-5, IL-12p40, and interfon-γ in BAL fluid and lung homogenate were measured by enzyme-linked immunosorbent assay. Unpaired t test was explored to compare the difference between two groups.Results On day 7 after bleomycin injection via trachea, CXCR3 knockout mice were protected from bleomycininduced lung injury as evidenced by fewer accumulation of inflammatory cells in the airway and lung interstitium compared with their wild type littermates ( P<0.05 ). Airway resistance was also lower in CXCR3 knockout mice compared with wild type mice (P<0.01 ). Significantly lower level of inflammatory cytokines release, including the altered production of IL-4 and IL-5 both in BAL fluid and lung tissue was seen in CXCR3 knockout mice than in wild type mice (both P<0.05).Conclusion CXCR3 signaling promotes inflammatory cells recruiting and initiates inflammatory cytokines cascade following endotracheal bleomycin administration, indicating that CXCR3 might be a therapeutic target for pulmonary injury.

    International Nuclear Information System (INIS)

    Cadmium (CD) is considered a metal of the 20th century to which all inhabitants of develop societies are exposed. Long-term occupational and environmental exposure to CD often results in renal dysfunction as the kidney is considered the critical target organ. The aim of this work was to evalutate both resporatory and renal manifestations induced by occupational exposure to CD compounds during brazing process, and suggesting a protocol for prevention and control for CD- induced health effects. This study was conducted on 20 males occupationally exposed workers. They are divided into two groups: Group-1 included (10) exposed smokers and group-2 included (10) exposed non-smokers. Results of both groups were compared with those of 10 healthy age and sex matched non-smokers. All subjects were subjected to detailed history taking and laboratory investigations including blood and urinary CD, liver profile (SGOT, SGPT and alkline phosphates), kindey function tests (blood urea, creatinine and urinary beta2- microglobulin). The level of Cd in the atmosphere of the work plase air was also assessed to detect the degree of exposure as it was about 6 times greater than thesave level (1 mu /m3).(1) This study demonstrated elevation levels of blood CD, urea, creatinine and urinary CD and beta2 -microglobulin for both exposed worker groups than the controls. In additions no appreciable were noted for liver function tests, although the levels fell within normal range

    The toxicity of selenium (Se) as an antioxidant supplement in the treatment of arthritis is debatable. In this study, Dextrin stabilized Se nanoparticles (SeNP) of size 64 nm ± 0.158 were used to explore its effects as a potent antioxidant with reduced toxicity in both in vitro and in vivo. In vitro toxicity of SeNP was determined using cytotoxicity assay. In vitro interactions of SeNP with DNA and protein was established. Subacute toxicity of SeNP was studied. Wistar rats with complete freunds adjuvant induced arthritis were used. Various concentrations of SeNP per kg body weight were fed orally daily upto to 21 days. Arthritic profile based on paw swelling, histopathological changes in joints, blood indices, and antioxidant enzymes level in organs such as liver, kidney, and spleen were investigated. Dextrin-SeNP when interacted with NIH-3T3 cells showed 15% cytotoxicity at 100 µg/mL whereas, bulk Se showed 95% at the same concentration. SeNP at 250 µg/mL showed protective effect on DNA. Interaction of SeNP with BSA showed increase in quenching of BSA fluorescence. SeNP did not show any subacute toxicity at concentration as high as 5 mg/kg b.w. in Wistar rats. SeNP at a concentration of 250 µg/kg b.w. acted as potent anti-inflammatory agent and significantly reduced (p kidney, and spleen were restored significantly (p normal at concentration of 100 µg/kg b.w. concluding SeNP at 500 µg/kg b.w. can be a potential antiarthritic drug supplement. © 2015 Wiley Periodicals, Inc.

  18. Phototherapy with low intensity laser in carrageenan-induced acute inflammatory process in mice paw - dosimetry studies

    International Nuclear Information System (INIS)

    The importance of modulation of inflammation on the treatment of inflammatory diseases and the difficulty in determining the laser irradiation parameters has led us to study the effects of different protocols of phototherapy with low intensity laser (power, energy, time and place of irradiation) in the treatment and prevention of edema in acute inflammatory process using the experimental model of paw edema induced by carrageenan (CGN) in three strains of mice (Balb-c, Swiss and C57BL/6). The first stage of the study evaluated different combinations of energy (1J and 3J) with different powers (30, 60 and 100mW) in Balb-C mice paw irradiated 1 and 2h after injection of CGN. The second stage studied different combinations of location (foot, inguinal lymph nodes and both) and exposure time (2 and 1h before, 1h and immediately before the CGN, 1 and 2h and 3.5 and 4.5h after CGN) using fixed irradiation parameters (1J, 100mW, 35J/cm2, spot area of 0.028 cm2). The third stage compared different strains of mice Balb-c and C57BL/6) in the best local and time parameters found in step 2. At all stages, we evaluated the change in paw volume by plethysmography and inflammatory infiltrate by histomorphometry or analysis of myeloperoxidase (MPO). The results showed that laser phototherapy treated and prevented edema and modulated the inflammatory process with paw and inguinal lymph nodes irradiations accordingly with the parameters and mice strain used.

    OBJECITVE:Improvement in lung function was reported after acupuncture treatment of chronic obstructive pulmonary disease (COPD),but little is known about the underlying mechanisms.Because an immune response imbalance could be seen in COPD,we hypothesize that electroacupuncture (EA) may play a role in regulating inflammatory cytokines and contribute to lung protection in a rat model of smoke-induced COPD.METHODS:A COPD model using male Sprague-Dawley rats exposed to cigarette smoke was established.The rats were randomly divided into four groups (control,sham,COPD,and COPD plus EA),and COPD model was evaluated by measuring pulmonary pathological changes and lung function.EA was applied to the acupuncture point Zusanli (ST36) for 30 min/d for 14 d in sham and COPD rats.Bronchoalveolar lavage fluid (BALF) was used to measure levels of tumor necrosis factor-α (TNF-α),interleukin-1β (IL-β),and malonaldehyde (MDA).RESULTS:Compared with the control rats,COPD rats had significant changes in lung resistance (RL) and lung compliance (CL) (both P<0.01),bronchi and bronchiole airway obstruction (P<0.01),and levels of MDA,TNF-α,and IL-1β (P<0.01).There were no significant differences between the control and the sham groups.Compared with the COPD rats,the COPD plus EA rats had decreased RL and increased CL (both P<0.05),and reduced bronchi and bronchiole airway obstruction (P<0.05,P<0.01,respectively),while levels of TNF-α,IL-1β,and MDA in BALF were lowered (P<0.05 and P<0.01,respectively).However,TNF-α and IL-1βlevels of the EA group rats remained higher than those of the control group (P<0.05).CONCLUSION:EA at ST36 can reduce lung injury in a COPD rat model,and beneficial effects may be related to down-regulation of inflammatory cytokines.The anti-inflammatory and antioxidant effects may prolong the clinical benefit of EA.

    Full Text Available Recent shifts in health policy direction in several countries have, on the whole, translated into self-management initiatives in the hope that this approach will address the growing impact of chronic disease. Dominant approaches to self-management tend to reinforce the current medical model of chronic disease and fail to adequately address the social factors that impact on the lives of people with chronic conditions. As part of a larger study focused on outcomes following a chronic disease, this paper explores the processes by which a chronic disease self-management (CDSM course impacted on participants. Five focus groups were conducted with participants and peer leaders of the course in both urban and rural regions of Queensland, Australia. The findings suggested that outcomes following CDSM courses depended on the complex interplay of four social factors, namely, social engagement, the development of a collective identity, the process of building collaborative coping capacity, and the establishment of exchange relationships. This study highlights the need for an approach to self-management that actively engages consumers in social relationships and addresses the context within which their lives (and diseases are enacted. This approach extends beyond the psychoeducational skills-based approach to self-management into a more ecological model for disease prevention.

    Full Text Available Increased urbanized lifestyle implies diet transition, reduced physical activity, mental strains with tobacco and alcohol use. That in turn, increases obesity, raises blood pressure, sugar and lipids, the common risk factors of interrelated non-communicable diseases (NCDs. Individual susceptibility and chronic inflammation make huge area of biomedical understanding. Behaviour modifying interventions are prudent for control but food choices also depend on affordability and availability. The low and middle income groups are driven to cheap unhealthy energy dense foods. The scenario of socioeconomic and nutrition transition in India is mounting the non communicable diseases at alarming speed and magnitude. Cardiac death has become number one killer already. Demographic transition is making the poorer and rural population vulnerable too. Prevention programmes are warranted with urgency. Whole grains, legumes, fish, fresh fruits and vegetables constitute healthy old food pattern. Dietary education under strained finances may be ineffective. Policies of food availability made in exclusion of consultation with health sector undermine prevention of NCDs. Recognition of diverse perspectives in social life and environment call for multisectorial engagement with appropriate interventions to reverse the NCDs epidemic.

    Full Text Available Abstract Background Genomic profiling of peripheral blood reveals altered immunity in chronic fatigue syndrome (CFS however interpretation remains challenging without immune demographic context. The object of this work is to identify modulation of specific immune functional components and restructuring of co-expression networks characteristic of CFS using the quantitative genomics of peripheral blood. Methods Gene sets were constructed a priori for CD4+ T cells, CD8+ T cells, CD19+ B cells, CD14+ monocytes and CD16+ neutrophils from published data. A group of 111 women were classified using empiric case definition (U.S. Centers for Disease Control and Prevention and unsupervised latent cluster analysis (LCA. Microarray profiles of peripheral blood were analyzed for expression of leukocyte-specific gene sets and characteristic changes in co-expression identified from topological evaluation of linear correlation networks. Results Median expression for a set of 6 genes preferentially up-regulated in CD19+ B cells was significantly lower in CFS (p = 0.01 due mainly to PTPRK and TSPAN3 expression. Although no other gene set was differentially expressed at p Conclusion Dissection of blood microarray profiles points to B cell dysfunction with coordinated immune activation supporting persistent inflammation and antibody-mediated NK cell modulation of T cell activity. This has clinical implications as the CD19+ genes identified could provide robust and biologically meaningful basis for the early detection and unambiguous phenotyping of CFS.

    Full Text Available Abstract Background In a recently published paper, Harvey and Wessely put forward a 'biopsychosocial' explanatory model for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS, which is proposed to be applicable to (chronic fatigue even when apparent medical causes are present. Methods Here, we review the model proposed by Harvey and Wessely, which is the rationale for behaviourally oriented interventions, such as cognitive behaviour therapy (CBT and graded exercise therapy (GET, and compare this model with a biological model, in which inflammatory, immune, oxidative and nitrosative (IO&NS pathways are key elements. Discussion Although human and animal studies have established that the pathophysiology of ME/CFS includes IO&NS pathways, these abnormalities are not included in the model proposed by Harvey and Wessely. Activation of IO&NS pathways is known to induce fatigue and somatic (F&S symptoms and can be induced or maintained by viral and bacterial infections, physical and psychosocial stressors, or organic disorders such as (autoimmune disorders. Studies have shown that ME/CFS and major depression are both clinical manifestations of shared IO&NS pathways, and that both disorders can be discriminated by specific symptoms and unshared or differentiating pathways. Interventions with CBT/GET are potentially harmful for many patients with ME/CFS, since the underlying pathophysiological abnormalities may be intensified by physical stressors. Conclusions In contrast to Harvey and Wessely's (biopsychosocial model for ME/CFS a bio(psychosocial model based upon IO&NS abnormalities is likely more appropriate to this complex disorder. In clinical practice, we suggest physicians should also explore the IO&NS pathophysiology by applying laboratory tests that examine the pathways involved.

    The tribal communities of North Eastern India rely on herbal medicine to cure various disease conditions. Ziziphus jujuba Mill. (Rhamnaceae) is one of such medicinal plants used for curing liver ailments, insomnia, anemia, diarrhea, diabetic complications, cancer, and loss of appetite. The present study was aimed to describe the protective ability of Z. jujuba root bark (ZJRB) against hepatic injury and chronic inflammation. Bioactivity guided fractionation of Z. jujuba methanol extract (ZJME) was performed using different solvents of increasing polarity viz. hexane (ZJHF), chloroform (ZJCF), ethyl acetate (ZJEAF), water (ZJWF), and residue (ZJMR). In vitro antioxidant results revealed that both ZJME and ZJWF possess strong antioxidant activity among all the fractions and mother extract tested. Further, ZJME and ZJWF showed significant protection against CCl4 intoxicated HepG2 cell lines by means of increased cell viability and decreased LDH levels compared to control group. ZJME at 200, 400 mg/kg and ZJWF at 50, 100 mg/kg inhibited the lipid peroxidation and significantly restored the liver function markers (AST, ALT, ALP, LDH, SOD, and CAT) and cytokine levels (TNF-α, Il-1β, and Il-10) in CCl4 induced acute liver damage in rats. All the results were comparable with standard drug silymarin which was further confirmed by histopathology analysis of liver. Similarly, inflammation and increase inflammatory cytokines levels of carrageenan induced paw edema in rats have been refurbished to normal levels on par with the standard drug indomethacin. ZJWF demonstrated potent response than ZJME in all the biological tests conducted. The results of the study signify the ability of ZJRB as good therapeutic agent for liver toxicity and chronic inflammation. PMID:27656145

    Loss of bone mass is a known complication of chronic inflammatory bowel disease (IBD) in children. The gold standard in the evaluation of bone mineral density (BMD) is dual energy X-ray absorptiometry (DXA). In this preliminary study we evaluated digital X-ray radiogrammetry (DXR) which estimates BMD (DXR-BMD) from hand radiographs in children with IBD. A total of 26 children with IBD (10 girls, 16 boys; age range 10-18 years) underwent DXR for the calculation of DXR-BMD and metacarpal index (DXR-MCI) using the Pronosco X-posure system. The results were compared with a local reference database and correlated with the results of DXA. DXR-BMD was 0.36-0.56 g/cm{sup 2} (median 0.46 g/cm{sup 2}) in Crohn disease patients and 0.38-0.63 g/cm{sup 2} (median 0.48 g/cm{sup 2}) in ulcerative colitis patients. DXR-MCI was 0.29-0.49 in Crohn disease patients and 0.28-0.53 in ulcerative colitis patients. The Z-scores were reduced to <-1 SD in five Crohn disease patients and in six ulcerative colitis patients. The coefficients (r) for the correlations between DXR-BMD and DXA-BMD were 0.78 for the lumbar spine and 0.61 for the proximal femur (P<0.01), and between DXR-MCI and DXA-BMD were 0.78 for the lumbar spine and 0.51 for the proximal femur (P<0.01). DXR seems to be able to estimate cortical osteopenia in children with chronic IBD. The DXR results showed a positive correlation with DXA results. (orig.)

    Active chronic osteomyelitis or complicating osteomyelitis (superimposed on diseases that changes the normal bone structure fractures, post-surgery, prosthesis) can be difficult to diagnose by anatomic radiological imaging modalities, like plain radiograph and CT. These diseases frequently cause also increased bone remodeling, leading to nonspecific uptake of Tc-99m-bone scan agents and gallium-67. New radiopharmaceuticals with greater inflammation/infection avidity and specificity are being developed, including the nonspecific polyclonal immunoglobulin (IgG) labeled with technetium-99. Tc-99m-IgG may be available as a ready to use kit, with no reported side effects, low patient absorbed radiation dose and low cost. The mechanism of IgG uptake at the inflammation site has not been fully elucidated yet. Specific (receptor linking, physico-chemical immunoglobulin properties) and nonspecific mechanisms (enhanced vascular permeability and macromolecular exudate) has been suggested. IgG scintigraphy results are affected by the isotope, labeling procedure adopted and characteristics of the inflammatory focus. Nineteen patients with suspected osteomyelitis (active chronic osteomyelitis or violated bone osteomyelitis) were studied by Tc-99m-IgG scintigraphy (directly labeled polyclonal immunoglobulin, Sandoglobuilina - Sandoz). All patients also underwent standard three-phase bone scintigraphy using methylene diphosphonate (Tc-99m-MDP), gallium-67 scintigraphy and plain radiographs. Infection was found in 8 sites. Sensitivity and specificity for Tc-99m-MDP, gallium-67 and Tc 99m-IgG scintigraphy were, respectively, 88 and 36%, 75 and 73%,88 and 82%. All patients with false positive IgG scintigraphies had previous surgery. Other current scintigraphic procedures used in the diagnosis of osteomyelitis are also reviewed. (author)

    Advanced chronic heart failure (CHF) is associated with abnormal haemostasis and inflammation, but it is not known how these abnormalities are related, whether they are modified by oral anticoagulants (OAT), or if they persist after successful heart transplantation. We studied 25 patients with CHF (New York Heart Association class IV, 10 of whom underwent heart transplantation) and 25 age- and sex-matched healthy controls by measuring their plasma levels of prothrombin fragment 1 + 2 (F1 + 2), thrombin-antithrombin (TAT) complexes, tissue plasminogen activator (t-PA), plasminogen activator inhibitor-1 (PAI-1), D-dimer, factor VII (FVII), fibrinogen, von Willebrand factor (VWF), tumour necrosis factor (TNF), soluble TNF receptor II (sTNFRII), interleukin 6 (IL-6), soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular cell adhesion molecule-1 (sVCAM-1), endothelial-selectin (E-selectin) and thrombomodulin. CHF patients had higher plasma levels of TAT, D-dimer, t-PA, fibrinogen, VWF, TNF, IL-6, sTNFRII, sVCAM-1 (P = 0.0001), sICAM-1 (P = 0.003) and thrombomodulin (P = 0.007) than controls. There were significant correlations (r = 0.414-0.595) between coagulation, fibrinolysis, endothelial dysfunction and inflammation parameters, which were lower in those patients treated with OATs. Heart transplantation led to reductions in fibrinogen (P = 0.001), VWF (P = 0.05), D-dimer (P = 0.05) and IL-6 levels (P = 0.05), but all the parameters remained significantly higher (P = 0.01-0.0001) than in the controls. Advanced CHF is associated with coagulation activation, endothelial dysfunction and increased proinflammatory cytokine levels. Most of these abnormalities parallel each other, tend to normalize in patients treated with OATs and, although reduced, persist in patients undergoing successful heart transplantation, despite the absence of clinical signs of CHF.

    Full Text Available Objective: This study aimed to evaluate the therapeutic effects of potato extract (PE on cigarette smoke (CS–induced chronic obstructive pulmonary disease (COPD. Methods: PE was first prepared by frozen centrifugation, and its amino acid composition was detected. Toxicity of PE was analyzed by changes in morphology, behavior, routine blood indexes, and biochemical criteria of mice. Then, the COPD rat model was established by CS exposure, and PE, doxofylline, and prednisolone acetate were used to treat these rats. After 45 days of treatment, the morphology and behavior of rats were recorded. In addition, the histopathology of lung tissue was evaluated by chest x-ray and hematoxylin and eosin staining. The expression of interleukine-10 (IL-10, tumor necrosis factor-α (TNF-α, and granulocyte colony-stimulating factor (G-CSF was detected in serum and lung tissue by enzyme-linked immunosorbent assay (ELISA and immunohistochemistry, respectively. Results: Various amino acids were identified in PE, and no toxicity was exhibited in mice. The CS-induced COPD rat model was successfully established, which exhibited significant thickened and disordered lung markings on 90% of the rats. After administering doxofylline and prednisolone acetate, inflammation symptoms were improved. However, side effects such as emaciation, weakness, and loosening of teeth appeared. In the PE group, obviously improved histopathology was observed in lung tissues. Meanwhile, it was revealed that PE could increase the expression of IL-10 and reduce the expression of TNF-α and G-CSF in COPD rats, and doxofylline and prednisolone acetate also elicited similar results. Conclusion: Our study suggests PE might be effective in the treatment of CS-induced COPD by inhibiting inflammation.

    Abstract Serhan and colleagues introduced the term "Resoleomics" in 1996 as the process of inflammation resolution. The major discovery of Serhan's work is that onset to conclusion of an inflammation is a controlled process of the immune system (IS) and not simply the consequence of an extinguished or "exhausted" immune reaction. Resoleomics can be considered as the evolutionary mechanism of restoring homeostatic balances after injury, inflammation and infection. Under normal circumstances, R...

    2015-12-01

    There are a variety of medical conditions associated with chronic sinonasal inflammation, including chronic rhinosinusitis (CRS) and cystic fibrosis. In particular, CRS can be divided into 2 major subgroups based on whether nasal polyps are present or absent. Unfortunately, clinical treatment strategies for patients with chronic sinonasal inflammation are limited, in part because the underlying mechanisms contributing to disease pathology are heterogeneous and not entirely known. It is hypothesized that alterations in mucociliary clearance, abnormalities in the sinonasal epithelial cell barrier, and tissue remodeling all contribute to the chronic inflammatory and tissue-deforming processes characteristic of CRS. Additionally, the host innate and adaptive immune responses are also significantly activated and might be involved in pathogenesis. Recent advancements in the understanding of CRS pathogenesis are highlighted in this review, with special focus placed on the roles of epithelial cells and the host immune response in patients with cystic fibrosis, CRS without nasal polyps, or CRS with nasal polyps.

    Full Text Available We report the case of a 14-year-old girl who developed postural orthostatic tachycardia syndrome (POTS with chronic fatigue 2 months following Gardasil vaccination. The patient suffered from persistent headaches, dizziness, recurrent syncope, poor motor coordination, weakness, fatigue, myalgias, numbness, tachycardia, dyspnea, visual disturbances, phonophobia, cognitive impairment, insomnia, gastrointestinal disturbances, and a weight loss of 20 pounds. The psychiatric evaluation ruled out the possibility that her symptoms were psychogenic or related to anxiety disorders. Furthermore, the patient tested positive for ANA (1:1280, lupus anticoagulant, and antiphospholipid. On clinical examination she presented livedo reticularis and was diagnosed with Raynaud’s syndrome. This case fulfills the criteria for the autoimmune/auto-inflammatory syndrome induced by adjuvants (ASIA. Because human papillomavirus vaccination is universally recommended to teenagers and because POTS frequently results in long-term disabilities (as was the case in our patient, a thorough follow-up of patients who present with relevant complaints after vaccination is strongly recommended.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is considered an auto-immune disorder. We evaluated expression of pSTAT1, T-bet, and pSTAT3 in circulating T-cells, B-cells, and monocytes and spontaneous production of interleukin-17 (IL17), interferon-gamma (IFN gamma), and interleukin-10 (IL10) by peripheral blood mononuclear cells (PBMCs) from 14 active CIDP patients compared with 6 patients with long-lasting remission and 20 controls. Active disease patients showed higher pSTAT1, T-bet, and pSTAT3 in CD4(+) T-cells than controls (p CIDP patients than controls (p = 0.0011, p = 0.0041, p = 0.0413, respectively) and remission patients (p = 0.0073, p = 0.0274, p = 0.0251, respectively). Moreover in CD8(+) T-cells, pSTAT3 expression was higher in active CIDP patients than in remission patients (p = 0.0345) and in controls (p = 0.0023). IL17 and IFN gamma production were significantly higher in active CIDP patients than in controls (p CIDP patients (p = 0.0073). IL10 levels were higher in active phase patients than in controls (p = 0.0334). Our data suggest that pSTAT1, T-bet, and pSTAT3 can be considered putative markers of disease activity and potential targets for specific therapies.

    A 17-year-old male with no medical history noticed weakness of his limbs with imbalance and subsequent finger tremors. Physical examination revealed features of polyneuropathy, including diffuse weakness, distal symmetrical numbness with impaired deep sensation and areflexia in all limbs. Postural tremor was present in fingers. Ataxia was apparent in both lower limbs, causing a wide-based gait with a positive Romberg sign. Cerebrospinal fluid contained elevated total protein without pleocytosis. A nerve conduction study disclosed demyelinating features with prolonged terminal latencies, slow velocities with delayed F-wave latencies, and prominent temporal dispersion. These findings led to diagnosis of typical chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) with notable feature of postural finger tremor and ataxia of unknown cause. These atypical features prompted us to examine neurofascin-155 (NF155) antibodies, which were positive. No significant improvement occurred after initial administration of intravenous immunoglobulin and subsequent plasma exchange. However, corticosteroids with intravenous pulse therapy followed by oral prednisolone significantly improved the symptoms. Patients with CIDP with anti-NF155 antibodies may have similar clinical features and constitute a CIDP subgroup. In such patients, corticosteroids may be more effective than intravenous immunoglobulin. Further studies are needed to define the features of this subgroup and determine effective therapy for CIDP.

    Full Text Available Abstract Objectives Intravenous immunoglobulin (IVIG has demonstrated improvement in chronic inflammatory demyelinating polyneuropathy (CIDP patients in placebo controlled trials. However, IVIG is also much more expensive than alternative treatments such as corticosteroids. The objective of the paper is to evaluate, from a Canadian perspective, the cost-effectiveness of IVIG compared to corticosteroid treatment of CIDP. Methods A markov model was used to evaluate the costs and QALYs for IVIG and corticosteroids over 5 years of treatment for CIDP. Patients initially responding to IVIG could remain a responder or relapse every 12 week model cycle. Non-responding IVIG patients were assumed to be switched to corticosteroids. Patients on corticosteroids were at risk of a number of adverse events (fracture, diabetes, glaucoma, cataract, serious infection in each cycle. Results Over the 5 year time horizon, the model estimated the incremental costs and QALYs of IVIG treatment compared to corticosteroid treatment to be $124,065 and 0.177 respectively. The incremental cost per QALY gained of IVIG was estimated to be $687,287. The cost per QALY of IVIG was sensitive to the assumptions regarding frequency and dosing of maintenance IVIG. Conclusions Based on common willingness to pay thresholds, IVIG would not be perceived as a cost effective treatment for CIDP.

    Neurological complications of AH1N1 vaccination such as Guillain-Barré syndrome were described in the previous years. Several reports suggest that hereditary neuropathies may be a predisposing factor for immune-mediated neuropathies. We report the case of a 54-year-old female who developed chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) 5 weeks after AH1N1 vaccination. She had no previous neurological history, but neurophysiological features led us to suspect an underlying hereditary neuropathy. PMP22 gene analysis showed a typical deletion, confirming the diagnosis of hereditary neuropathy with liability to pressure palsies (HNPP). We observed a significant clinical and neurophysiological improvement of the neuropathy after intravenous immunoglobulin treatment. This is, to our knowledge, the first reported case of CIDP potentially triggered by AH1N1 vaccination. This and previous observations suggest that genetic-determined neuropathies could predispose to the occurrence of immune-mediated neuropathies. One must recall the possibility of a superimposed hereditary neuropathy like HNPP in patients with a clinical presentation of CIDP, especially when positive family history or unexpected neurophysiological features are present.

    In the past decades patients with hemophilia were infected commonly by hepatitis C virus (HCV) and a significant number of patients are infected chronically. Focusing on the role of the immune system for controlling and or maintaining HCV infection, the leukocyte and cytokine profiles of peripheral blood from hemophilia A patients and other patients with and without HCV infection were studied. The results demonstrated that hemophilia A is characterized by a general state of circulating leukocytes activation along with an overall increase in the frequency of IL-6 and IL-10 with decrease of IL-8 and IL-12. HCV infection of patients with hemophilia A does not influence further the activation state of circulating leukocytes but is accompanied by lower levels of alanine transaminase (ALT) and a prominent anti-inflammatory/regulatory serum cytokine pattern, mediated by IL-4 and IL-10. Additionally, the results demonstrated that hemophilia A patients infected with HCV displaying No/Low antibody response to C33c and C22 have significant lower viral load and higher serum levels of IL-12 and IL-4. This finding suggests that the differential RIBA reactivity to C33c/C22 HCV core proteins may have a putative value as a prognostic biomarker for the infection in hemophilia A patients.

    Full Text Available Abstract Background At term, cervical ripening in coordination with uterine contractions becomes a prerequisite for a normal vaginal delivery. Currently, cervical ripening is considered to occur independently from uterine contractions. Many evidences suggest that cervical ripening resembles an inflammatory process. Comparatively little attention has been paid to the increased flexibility of the pelvic symphysis that occurs in many species to enable safe delivery. The aim of this study was to investigate whether the guinea-pig interpubic joint relaxation process observed during late pregnancy and parturition resembles an inflammatory process. Methods Samples of pubic symphysis were taken from pregnant guinea-pigs sacrificed along gestation, parturition and postpartum. Serial sections of paraffin-embedded tissues were used to measure the interpubic distance on digitalized images, stained with Giemsa to quantify leukocyte infiltration and to describe the vascular area changes, or studied by the picrosirius-polarization method to evaluate collagen remodeling. P4 and E2 serum levels were measured by a sequential immunometric assay. Results Data showed that the pubic relaxation is associated with an increase in collagen remodeling. In addition, a positive correlation between E2 serum levels and the increase in the interpubic distance was found. On the other hand, a leukocyte infiltration in the interpubic tissue around parturition was described, with the presence of almost all inflammatory cells types. At the same time, histological images show an increase in vascular area (angiogenesis. Eosinophils reached their highest level immediately before parturition; whereas for the neutrophilic and mononuclear infiltration higher values were recorded one day after parturition. Correlation analysis showed that eosinophils and mononuclear cells were positively correlated with E2 levels, but only eosinophilic infiltration was associated with collagen remodeling

    Aim Evaluation of mannitol-MRI in patients with suspected or established Crohn's disease (CD). 75 patients with suspected or established Crohn's disease were included. 1.5 l of mannitol-solution were administered orally within 1 h before imaging.A rectal filling was also employed.Butylscopolamin was applied i.v. Native-sequences were acquired. T1w sequences (axial, coronal) were acquired before and after (fs-T1-w-BH) i.v.Gd-DTPA.Additionally a dynamic CM-study was performed. In 45% of the examinations good image quality was achieved. In 28% opacification of the terminal ileum was insufficient. However, diagnostic assessment was possible. Motion artifacts due to breathing were rare, artifacts due to peristalsis were noted in 16% of the examinations. Alterations indicative to CD were found in 69% of the patients.The SI-increase of the thickened bowel-wall was significantly higher than the increase of not thickened wall (117 vs.75%; p = 0,001 in t-test).We detected stenoses in 56%, fistulas in 23% and an abscess in one patient. Mannitol-MRI is a valuable method in the diagnostic work-up of inflammatory bowel disease. Improvement of distal distension should be attempted, because of the good acceptance of the patients and high diagnostical value. (orig.)

    The effects of Arnica montana 6cH on the individual modulation of acute inflammation kinetics in rats were evaluated. Adult male Wistar rats were inoculated with 1% carrageenan into the footpad and treated with Arnica montana 6cH, dexamethasone (4.0 mg/kg; positive control) or 5% hydroalcoholic solution (negative control), per os, each 15 minutes, between 30 and 180 minutes after the irritant inoculation. Histopathological and immunohistochemistry procedures were done in order to get a panel of inflammatory positive cells for CD3 (T lymphocytes), CD45RA (B lymphocytes), CD18 (beta 2 integrin), CD163 (ED2 protein), CD54 (ICAM-1), and MAC 387 (monocytes and macrophages). The statistical treatment of data included a posteriori classification of animals from each group (N = 20) in two subgroups presenting spontaneous precocious or late oedema. Animals that presented precocious oedema were less responsible to Arnica montana 6cH in relation to hemodynamic changes. Instead, rats that exhibited late oedema presented less intense oedema (P = .01), lower percentage of mast cell degranulation (P = .0001), and increase in lymphatic vessels diameter (P = .05). The data suggest an individually qualitative adjustment of inflammatory vascular events by Arnica montana 6cH.

    In response to social-evaluative threat induced in the laboratory, lower (compared to higher) subjective social class of a participant predicts greater increases in the inflammatory cytokine interleukin-6 (IL-6). In spite of the interpersonal nature of social-evaluation, little work has explored whether characteristics of the evaluator shape physiological responses in this context. In the current study, in a sample of 190 college students (male=66), we explored whether one's subjective social class interacts with the perceived social class of an evaluator to predict changes in Oral Mucosal Transudate (OMT) IL-6 in response to the Trier Social Stress Test (TSST). Participants were randomly assigned to be the speaker or the evaluator. Extending past work, we found that while speakers low in subjective social class consistently respond with strong increases in IL-6 regardless of their perception of their evaluator's social class, speakers high in subjective social class responded with greater increases in IL-6 when their evaluator was perceived as high social class compared to when they were perceived as low social class. This finding highlights the importance of perceptions of the evaluator in informing inflammatory responses to a social-evaluative task.

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

  6. Inflammatory process decrease by gallium-aluminium-arsenide (GaAlAs) low intensity laser irradiation on postoperative extraction of impacted lower third molar

    International Nuclear Information System (INIS)

    This study aimed the observation of inflammatory process decrease by the use of GaAlAs Low Intensity Laser (λ=830 nm; 40 mW) irradiation. Five patients were selected and submitted to surgery of impacted lower third molars, both right and left sides at different occasions. On a first stage, a tooth of a random chosen side - right or left - was extracted by conventional surgery, without LILT. The inflammatory process was measured at postoperative on the first, third and seventh days. This side was then called 'control side'. After 21 days, period in which the inflammatory process of the first surgery was terminated, the other side surgery took place, this time using LILT (4 J at four spots) at postoperative, first and third days. As the previous surgery, the inflammatory process was also measured at postoperative on the first, third and seventh days. This side was called 'experimental or lased side'. The inflammatory process was evaluated by measuring its four characteristic signs: swelling, pain, color and temperature. It was clearly observed a decrease for swelling, pain and color on the lased side which presented significant inference and descriptive statistics. It can be concluded that GaAlAs Low Intensity Laser (λ=830 nm) can surely be used as an additional and important anti-inflammatory source on impacted lower third molar surgeries. (author)

    Background: : Psoriasis (PSO and atopic eczema (AE are chronic inflammatory disorders that primarily affect the skin. Data on cardiovascular comorbidity in PSO is scarce, and studies on the association of cardiovascular disease/cardiovascular risk factors and AE are missing. Methods: We performed two separate case-control studies for PSO and AE utilising an administrative health care database including approximately 250,000 individuals from Germany. Cases with AE (n=6,296 and cases with PSO (n=3,156 were individually-matched (1:1 to controls with the same age and sex. Odds ratios (OR and 95% confidence intervals (95%CI were calculated based on the observed prevalences of cardiovascular morbidity among cases and controls.

    Results: Patients with AE had a higher risk of obesity (OR,95%CI 1.24, 1.07-1.44. None of the other cardiovascular risk factors or diseases studied was associated with AE. PSO was significantly associated with hypertension (OR,95%CI 1.45, 1.27-1.66, diabetes mellitus type-2 (OR,95%CI 1.35, 1.13-1.61, obesity (OR,95%CI 1.58, 1.34-1.85, dyslipidemia (OR,95%CI 1.42, 1.14-1.77, and atherosclerosis (OR,95%CI 1.81, 1.37-2.41. Despite their unfavorable cardiovascular risk factor profile, patients with PSO were not at increased risk of adverse cardiovascular events (myocardial infarction OR,95%CI 1.14, 0.74-1.77; cerebral apoplexy OR,95%CI 0.94, 0.57-1.55.

    Conclusions: Chronic inflammation due to AE does not appear to cause adverse cardiovascular comorbidities. In contrast, PSO is associated with an adverse cardiovascular risk factor profile, but this does not necessarily appear to translate into a higher risk for cardiovascular events. This study does not rule out that specific treatments for AE or PSO modify the risk of cardiovascular disease.

    Inflammatory bowel diseases (IBD) are chronic inflammatory conditions of the gastrointestinal tract,which clinically present as one of two disorders, Crohn's disease or ulcerative colitis. Mainstays of drug treatments for IBD include aminosalicylates, corticosteroids and immunosuppressants such as azathioprine, methotrexate and cyclosporin. Advances in basic research of the pathophysiological process in IBD have been applied to generate a variety of new therapeutics targeting at different levels of the inflammatory processes. New therapies are classified as: (1) Anti-TNFα antibodies; (2) Recombinant cytokines; (3) Selective adhesion blockade;(4) Growth factors; (5) Innate immunostimulation; (6) Nucleic acid based therapies; (7) Gene therapy; (8) Autologous bone-marrow transplantation; (9) Helminths and (10) Extracorporeal immunomodulation. All treatments have the potential to provide more effective and safe treatment for IBD.

    The use of biologic drugs has been linked with the paradoxical development of systemic and organ specific autoimmune processes. The aim of this study was to describe the features of biologics-induced autoimmune renal disorders (AIRD) through a systematic review and a cohort study of 707 adult patients affected with Rheumatoid Arthritis (RA), Ankylosing Spondylitis (SA) and Psoriatic Arthritis (PsA). The literature search identified 2687 articles of which 21 were considered relevant for the present study, accounting for 26 case reports. The cohort analysis retrieved 3 cases. According to clinical manifestations and kidney histology the identified AIRD cases were classified as: a) glomerulonephritis associated with systemic vasculitis (GNSV), b) glomerulonephritis in lupus-like syndrome (GNLS), c) isolated autoimmune renal disorders (IARD). Twenty-two out of 29 cases with AIRD were reported in patients affected by RA, 5 in AS and 2 in PsA. The biologic drug most frequently associated with development of AIRD was Etanercept (15 cases, 51.7%), followed by Adalimumab (9 cases, 31.0%) and Infliximab (3 cases, 10.3%) while Tocilizumab and Abatacept were reported in 1 case (3.4%) for each. Thirteen out of 29 (44.8%) cases were classified as affected by IARD, 12 (41.3%) as GNSV and 4 (13.9%) as GNLS. Worse prognosis was associated with GNSV and lack of biologic withdrawal. Although rare, AIRD may be life-threatening and may lead to renal failure and death. If AIRD occurs, biologic drugs must be stopped and patient should be treated according to clinical manifestations and kidney biopsy findings.

    胞对LPS刺激产生耐受.%AIM: To evaluate the immune state in rats with chronic Clonorchis sinesis (Cs) infestation by investigating the effects of Cs on macrophage polarization and inflammatory reactions. METHODS: Sprague-Dawley rats were used in the study. Chronic Cs infestation model was reproduced by intragastric perfusion with Cs eggs. Twenty rats were randomly divided into normal group ( n = 10) and Cs infestation group ( n = 10). The serum levels of interleukin (IL-4) and IL-10, tumor necrosis factor α(TNF-α) and interferon -γ (IFN-γ) were detected by ELBA. The macrophages were harvested by peritoneal lavage. The differentiation proportion of Ml and M2 macrophages were detected by flow cytometry. The macrophages were divided into control group, normal group and chronic Cs infestation group according to the sources of macrophages. The levels of TNF-α and IL-10 in the culture supernatants were detected by ELISA at 0, 2, 12 and 24 h after lipopolysaccharide (LPS, 10 μg/L) stimulation in vitro. RESULTS: Compared with normal group, chronic Cs infestation increased the serum levels of TNF-α, IFN-γ, IL-4 and IL-10. The differentiation proportion of Ml detected by flow cytome-try was 92. 1% in normal group and that of M2 macrophages was 93. 8% in Cs infestation group. The levels TNF-α and IL-10 in culture supernatants were increased at 2 ~ 24 h after LPS stimulation both in normal group and Cs infestation group, but the levels of TNF-a were lower in chronic Cs infestation group than that in normal group at 2 h, 12 h and 24 h after LPS stimulation. The level of anti-inflammatory cytokine IL-10 was higher in Cs infestation group than that in normal group at 2 h, 12 h and 24 h after LPS stimulation. CONCLUSION: Chronic Cs infestation increases the serum levels of both pro-inflammatory cytokines and anti-inflammatory cytokines, thus inducing the polarization of M2 macrophages. The macrophages derived from chronic Cs-infected rats produce tolerance in the inflammatory process against LPS in

    Full Text Available Leishmania major parasites reside and multiply in late endosomal compartments of host phagocytic cells. Immune control of Leishmania growth absolutely requires expression of inducible Nitric Oxide Synthase (iNOS/NOS2 and subsequent production of NO. Here, we show that CD11b+ CD11c+ Ly-6C+ MHC-II+ cells are the main iNOS-producing cells in the footpad lesion and in the draining lymph node of Leishmania major-infected C57BL/6 mice. These cells are phenotypically similar to iNOS-producing inflammatory DC (iNOS-DC observed in the mouse models of Listeria monocytogenes and Brucella melitensis infection. The use of DsRed-expressing parasites demonstrated that these iNOS-producing cells are the major infected population in the lesions and the draining lymph nodes. Analysis of various genetically deficient mouse strains revealed the requirement of CCR2 expression for the recruitment of iNOS-DC in the draining lymph nodes, whereas their activation is strongly dependent on CD40, IL-12, IFN-gamma and MyD88 molecules with a partial contribution of TNF-alpha and TLR9. In contrast, STAT-6 deficiency enhanced iNOS-DC recruitment and activation in susceptible BALB/c mice, demonstrating a key role for IL-4 and IL-13 as negative regulators. Taken together, our results suggest that iNOS-DC represent a major class of Th1-regulated effector cell population and constitute the most frequent infected cell type during chronic Leishmania major infection phase of C57BL/6 resistant mice.

    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.

    Several studies point to the increased risk of reactivation of latent tuberculosis infection (LTBI) in patients with chronic inflammatory arthritis (CIAs) after using tumour necrosis factor (TNF)α blockers. To study the incidence of active mycobacterial infections (aMI) in patients starting TNF α blockers, 262 patients were included in this study: 109 with rheumatoid arthritis (RA), 93 with ankylosing spondylitis (AS), 44 with juvenile idiopathic arthritis (JIA) and 16 with psoriatic arthritis (PsA). All patients had indication for anti-TNF α therapy. Epidemiologic and clinical data were evaluated and a simple X-ray and tuberculin skin test (TST) were performed. The control group included 215 healthy individuals. The follow-up was 48 months to identify cases of aMI. TST positivity was higher in patients with AS (37.6%) than in RA (12.8%), PsA (18.8%) and JIA (6.8%) (p < 0.001). In the control group, TST positivity was 32.7%. Nine (3.43%) patients were diagnosed with aMI. The overall incidence rate of aMI was 86.93/100,000 person-years [95% confidence interval (CI) 23.6-217.9] for patients and 35.79/100,000 person-years (95% CI 12.4-69.6) for control group (p < 0.001). All patients who developed aMI had no evidence of LTBI at the baseline evaluation. Patients with CIA starting TNF α blockers and no evidence of LTBI at baseline, particularly with nonreactive TST, may have higher risk of aMI. PMID:26560983

    Syndromes with chronic daily headache include chronic migraine (CM). The reason for the transformation of migraine into chronic daily headache is still unknown. In this study, we aimed to evaluate heat pain thresholds and event-related potentials following CO(2)-laser thermal stimulation (LEPS) in hand and facial regions in patients with CM, to show changes in nociceptive brain responses related to dysfunction of pain elaboration at the cortical level. The results were compared with findings from normal control subjects and from subjects who suffer from migraine without aura. The effects of stimulus intensity, subjective pain perception and attention were monitored and compared with features of the LEPS. Twenty-five CM patients, 15 subjects suffering from migraine without aura and 15 normal control subjects were enrolled in the study. LEPS amplitude variation was reduced in CM patients with respect to the perceived stimulus intensity, in comparison with migraine without aura patients and control subjects. In both headache groups, the distraction from the painful laser stimulus induced by an arithmetic task failed to suppress the LEPS amplitude, in comparison with control subjects. These results suggest an abnormal cortical processing of nociceptive input in CM patients, which could lead to the chronic state of pain. In both headache groups, an inability to reduce pain elaboration during an alternative cognitive task emerged as an abnormal behaviour probably predisposing to migraine.

    Full Text Available Abstract Background Inspiratory occlusion evoked cortical potentials (the respiratory related-evoked potentials, RREPs bear witness of the processing of changes in respiratory mechanics by the brain. Their impairment in children having suffered near-fatal asthma supports the hypothesis that relates asthma severity with the ability of the patients to perceive respiratory changes. It is not known whether or not chronic respiratory defects are associated with an alteration in brain processing of inspiratory loads. The aim of the present study was to compare the presence, the latencies and the amplitudes of the P1, N1, P2, and N2 components of the RREPs in children with chronic lung or neuromuscular disease. Methods RREPs were recorded in patients with stable asthma (n = 21, cystic fibrosis (n = 32, and neuromuscular disease (n = 16 and in healthy controls (n = 11. Results The 4 RREP components were significantly less frequently observed in the 3 groups of patients than in the controls. Within the patient groups, the N1 and the P2 components were significantly less frequently observed in the patients with asthma (16/21 for both components and cystic fibrosis (20/32 and 14/32 than in the patients with neuromuscular disease (15/16 and 16/16. When present, the latencies and amplitudes of the 4 components were similar in the patients and controls. Conclusion Chronic ventilatory defects in children are associated with an impaired cortical processing of afferent respiratory signals.

    Full Text Available Recent evidence shows that the renin-angiotensin system is a crucial player in atherosclerotic processes. The regulation of arterial blood pressure was considered from its first description of the main mechanism involved. Vasoconstriction (mediated by angiotensin II and salt and water retention (mainly due to aldosterone were classically considered as pivotal proatherosclerotic activities. However, basic research and animal studies strongly support angiotensin II as a proinflammatory mediator, which directly induces atherosclerotic plaque development and heart remodeling. Furthermore, angiotensin II induces proatherosclerotic cytokine and chemokine secretion and increases endothelial dysfunction. Accordingly, the pharmacological inhibition of the renin-angiotensin system improves prognosis of patients with cardiovascular disease even in settings of normal baseline blood pressure. In the present review, we focused on angiotensin-convertingenzyme (ACE inhibitors, angiotensin II receptor blockers (ARBs, and renin inhibitors to update the direct activities of the renin-angiotensin system in inflammatory processes governing atherosclerosis.

    Full Text Available According to our study, diseases of the nose and paranasal sinuses were found in 59.4% of patients with acute and chronic leukemias. In chronic leukemia purulent-inflammatory diseases had abortive clinical manifestation. In acute leukemia, especially during the induction of remission, purulent-inflammatory diseases of the nose and paranasal sinuses were associated with significant signs of purulent process. Inflammatory diseases of the paranasal sinuses are manifested by pronounced shift of hematological indices of intoxication that indicates increase of autointoxication, disturbance of adaptation mechanisms and transition of adaptive-compensatory immunological reactions in damaging ones.
