    2006-05-01

    Chronic inflammatory rhinitis is commonly found in dogs with chronic nasal disease and is characterized by lymphoplasmacytic infiltrates in the nasal mucosa in the absence of an obvious etiologic process. The pathogenesis of lymphoplasmacytic rhinitis remains unknown. Animals respond poorly to antibiotics, oral glucocorticoids, and antihistamines, making primary infectious, immune-mediated, or allergic etiologies unlikely. Aberrant immune response to inhaled organisms or allergens may induce inflammation in some animals. Common clinical signs include nasal discharge, sneezing, coughing, epistaxis, and stertor. Diagnosis is made by performing a thorough history, physical examination, radiography or advanced imaging (via computed tomography or magnetic resonance imaging), rhinoscopy, and nasal mucosal biopsy to rule out primary etiologies of nasal discharge. Treatment strategies have included various antibiotics, antihistamines, oral and inhalant steroids, nonsteroidal antiinflammatories, and antifungal medications. Some dogs may respond partially to doxycycline or azithromycin, although it is unclear whether response is related to antimicrobial or antiinflammatory properties of these drugs. Hydration of the nasal cavity through nasal drops or aerosols may limit nasal discharge, and some animals may improve with inhalant (but rarely oral) glucocorticoids. PMID:16711613

    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 sta...

    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.

    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 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.

    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.

  10. Inflammatory chronic disease of the colon: How to image

    International Nuclear Information System (INIS)

    Inflammatory bowel disease, including Crohn's disease and UC, is a chronic disorder of the gastrointestinal tract. The inflammatory process in UC is confined to the mucosa and submucosa and it involves only the colon. In contrast, in Crohn's disease the inflammation process extends through the bowel wall layers and it can involve any part of gastrointestinal tract. Moreover, inflammatory bowel disease of the colon may be associated with complications, such as toxic megacolon, fulminant colitis, acute bleeding, fistulas and abscesses. Radiographic imaging studies are useful for the diagnosis of inflammatory bowel disease, and may be used to assess the extent and severity of disease, rule out complications, and monitor the response to therapy. The double-contrast barium study is a valuable technique for diagnosing inflammatory bowel disease colonic alterations, even in patients with early mucosal abnormalities. The earliest finding of UC is characterized by a fine granular appeareance of the colonic mucosa, usually involving the rectosigmoid junction. In chronic UC double-contrast enema may reveal marked colonic shortening with tubular narrowing of the bowel and loss of haustration. The earliest radiographics findings of Crohn's disease are represented by aphthous ulcers. As disease progresses, aphthous ulcers may enlarge and coalesce to form stellate or linear areas of ulceration. In advanced Crohn's disease, transmural ulceration may lead to the development of fissures, sinus tracts, fistulas, and abscesses. Cross sectional studies such as computed tomography, magnetic resonance imaging and sometimes ultrasound, are useful alternative tools not only in the assessment of bowel wall abnormalities, but also for the assessment of extraluminal alterations in patients with advanced disease

    2013-08-01

    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.

    Full Text Available Introduction. Atherosclerosis is a progressive, multifactorial, diffuse, multisystemic, chronic, inflammatory disease, which is manifested by disorders of vascular, immune and metabolic system. Pathogenesis of this disease is not fully understood. Endothelial Dysfunction and Inflammatory Process. Endothelial dysfunction is recognized as the crucial step in atherogenesis. A lot of studies have confirmed the involvement of various mediators of inflammation in initial proatherogenic processes, such as the upregulation of adhesion molecules on endothelial cells, binding of low density lipoproteins to endothelium, activation of macrophages and proliferation of vascular smooth muscle cells. Fatty stain and Inflammatory Process. Fatty stain consists of foam cell accumulation. After foam cell formation, mediators of inflammation initiate a series of intracellular events that include the induction of inflammatory cytokines. Thus, a vicious circle of inflammation, modification of lipoproteins and further inflammation can be maintained in the artery. Transitory Lesion and Inflammatory Process. In transitory lesion intensive phagocytosis of oxidized low density lipoproteins additionally activates monocytes and macrophages and consequently facilitates and exacerbates the inflammatory response. Fibrotic Plaque and Inflammatory Process. Inflammatory process, matrix-degrading metalloproteinases activity, platelets aggregation and smooth muscle cells proliferation play a central role in development of fibrotic plaque. Complex Lesion and Inflammatory Process. It has been shown that inflammation is closely related to the development of atherosclerotic plaque rupture. Conclusion. The contribution of inflammatory process has become increasingly meaningful in understanding the initiation, progression and clinical manifestations of atherosclerosis.

    240 patients with chronic otitis media (COM) were studied: 166 ears termed as non cholesteatomatous otitis media and 74 with cholesteatoma. In 38 ears an aural polyp was found with no evidence of cholesteatoma in 19 ears (11.4%) whereas a cholesteatoma was present in the remaining 19 ears. The histology of the polyp and the characteristics of the chronic process were matched: a) The aural polyp is an infrequent complication in COM. b) After histological analysis was found to present two different pictures: The inflammatory reaction polyp, present in non cholesteatomatous COM; and the polyp with granulation tissue and foreign body reaction (keratina) usually found in cholesteatomatous COM. c) The finding of granulation tissue reaction and keratina in an aural polyp is a good predictor for the presence of a cholesteatoma.

    Decreased appetite and involuntary weight loss are common occurrences in chronic disease and have a negative impact on both quality of life and eventual mortality. Weight loss in chronic disease comes from both fat and lean mass, and is known as cachexia. Both alterations in appetite and body weight loss occur in a wide variety of diseases, including cancer, heart failure, renal failure, chronic obstructive pulmonary disease and HIV.

    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 ...

    2012-01-01

    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.

    2010-12-01

    Decreased appetite and involuntary weight loss are common occurrences in chronic disease and have a negative impact on both quality of life and eventual mortality. Weight loss in chronic disease comes from both fat and lean mass, and is known as cachexia. Both alterations in appetite and body weight loss occur in a wide variety of diseases, including cancer, heart failure, renal failure, chronic obstructive pulmonary disease and HIV. An increase in circulating inflammatory cytokines has been implicated as a uniting pathogenic mechanism of cachexia and associated anorexia. One of the targets of inflammatory mediators is the central nervous system, and in particular feeding centers in the hypothalamus located in the ventral diencephalon. Current research has begun to elucidate the mechanisms by which inflammation reaches the hypothalamus, and the neural substrates underlying inflammatory anorexia. Research into these neural mechanisms has suggested new therapeutic possibilities, which have produced promising results in preclinical and clinical trials. This review will discuss inflammatory signaling in the hypothalamus that mediates anorexia, and the opportunities for therapeutic intervention that these mechanisms present. PMID:21475703

    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.

    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

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

    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.

    Objective: To study the correlationship between the serum levels of PAB, CHE, TBA, ALT and the severity of the disease process in patients with chronic virus B hepatitis. Methods: Serum levels of PAB, CHE, ALT (with biochemical methods) and TBA (with RIA) were examined in 93 patients with biopsy proven virus B hepatitis and 46 controls. Results: The 93 patients were of two groups: a less advanced group (n=51) and a more advanced group (n=42). Serum TBA, ALT levels were significnatly higher and serum PAB, CHE levels were significantly lower in the more advanced group than those in the less advanced group (P0 to s4. Changes of levels of ALT were of no regular pattern, but serum levels of TBA regularly increased and levels of PAB, CHE regularly decreased as the fibrosis grading proceeded from s0 to s4 and the differences between the levels in s4 and any other grading were significant (P<0.01). Conclusion: Combined determination of these serum markers might reflect the degree of inflammatory process and hepatic fibrosis in patients with virus B hepatitis, leading to earlier detection of cirrhosis.

    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.)

    Zsuzsa eSzondy

    2014-08-01

    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.

    This article considers several issues of current interest relating to the management of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), including diagnostic pitfalls, differences between CIDP patients with and without concurrent diabetes mellitus and how to best measure treatment response in daily practice. Despite the availability of diagnostic criteria, many patients diagnosed with CIDP do not meet these criteria; reasons for misdiagnosis are discussed. There are no definitive predictors of treatment response in CIDP; however, certain clinical and electrophysiological characteristics may be helpful. Patients with CIDP and concurrent diabetes present an additional diagnostic challenge; the differences between these groups, including possible differences in response predictors are discussed. Finally, the most appropriate outcome measures for use in daily practice are considered. PMID:27230584

    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

    BACKGROUND AND PURPOSE: Subcutaneous immunoglobulin (SCIG) is superior to placebo treatment for maintenance of muscle strength during 12 weeks in patients with chronic inflammatory demyelinating polyneuropathy (CIDP). The present study evaluated whether SCIG preserves muscle strength for 1 year in...... an open-label follow-up study. METHODS: Seventeen responders to intravenous immunoglobulin (IVIG) who had participated in the previous study of SCIG versus placebo in CIDP were included. After one IVIG infusion 2 weeks prior to baseline, all continued on SCIG treatment at weekly equal dosage and were...... and ODSS remained unchanged. CONCLUSION: SCIG preserves muscle strength and functional ability in patients with CIDP who previously responded to IVIG. SCIG should be considered as an alternative in long-term treatment of CIDP patients....

    Blood in healthy organisms is seen as a 'sterile' environment: it lacks proliferating microbes. Dormant or not-immediately-culturable forms are not absent, however, as intracellular dormancy is well established. We highlight here that a great many pathogens can survive in blood and inside erythrocytes. 'Non-culturability', reflected by discrepancies between plate counts and total counts, is commonplace in environmental microbiology. It is overcome by improved culturing methods, and we asked how common this would be in blood. A number of recent, sequence-based and ultramicroscopic studies have uncovered an authentic blood microbiome in a number of non-communicable diseases. The chief origin of these microbes is the gut microbiome (especially when it shifts composition to a pathogenic state, known as 'dysbiosis'). Another source is microbes translocated from the oral cavity. 'Dysbiosis' is also used to describe translocation of cells into blood or other tissues. To avoid ambiguity, we here use the term 'atopobiosis' for microbes that appear in places other than their normal location. Atopobiosis may contribute to the dynamics of a variety of inflammatory diseases. Overall, it seems that many more chronic, non-communicable, inflammatory diseases may have a microbial component than are presently considered, and may be treatable using bactericidal antibiotics or vaccines.

  1. 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.

    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

  6. Inflammatory mechanisms in patients with chronic obstructive pulmonary disease.

    2016-07-01

    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.

    Steno Rinalduzzi

    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.

    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.

  10. 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

    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.

    Allison J Brager

    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 A literature review is dedicated to one of the most urgent problems of modern andrology – the treatment of chronic non-bacterial prostatitis (CP with inflammatory component. Over the past decades, despite numerous methods of prevention and treatment offered by the Russian and foreign urologists, the incidence of CP has been steadily progressing. Treatment of patients with CP should be comprehensive and be sure to include the effects on all the links in the pathogenesis of the disease. It is different depending on the age of the patient and the presence and nature of CP manifestations, including changes in mental status, especially disease progression, stage and phase inflammatory activity in the prostate, the degree of involvement in the disease process nearby organs, immune status and other factors. The proposed scientific review covers the basic techniques of therapeutic effect on patients with CP. Given in article data allows a more rational approach to the treatment of these patients.

    2016-01-01

    Background Human endogenous retroviruses HERV-W encode a pro-inflammatory protein, named MSRV-Env from its original identification in Multiple Sclerosis. Though not detected in various neurological controls, MSRV-Env was found in patients with chronic inflammatory demyelinating polyradiculoneuropathies (CIDPs). This study investigated the expression of MSRV in CIDP and evaluated relevant MSRV-Env pathogenic effects. Methods 50 CIDP patients, 19 other neurological controls (ONDs) and 65 healthy blood donors (HBDs) were recruited from two different countries. MSRV-env and -pol transcripts, IL6 and CXCL10 levels were quantified from blood samples. MSRV-Env immunohistology was performed in distal sensory nerves from CIDP and neurological controls biopsies. MSRV-Env pathogenic effects and mode of action were assayed in cultured primary human Schwann cells (HSCs). Findings In both cohorts, MSRV-env and -pol transcripts, IL6 positivity prevalence and CXCL10 levels were significantly elevated in CIDP patients when compared to HBDs and ONDs (statistically significant in all comparisons). MSRV-Env protein was detected in Schwann cells in 5/7 CIDP biopsies. HSC exposed to or transfected with MSRV-env presented a strong increase of IL6 and CXCL10 transcripts and protein secretion. These pathogenic effects on HSC were inhibited by GNbAC1, a highly specific and neutralizing humanized monoclonal antibody targeting MSRV-Env. Interpretation The present study showed that MSRV-Env may trigger the release of critical immune mediators proposed as instrumental factors involved in the pathophysiology of CIDP. Significant MSRV-Env expression was detected in a significant proportion of patients with CIDP, in which it may play a role according to its presently observed effects on Schwann cells along with previously known effects on immune cells. Experimental results also suggest that a biomarker-driven therapeutic strategy targeting this protein with a neutralizing antibody such as GNbAC1

    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.

  2. Chronic inflammatory diseases are stimulated by current lifestyle: how diet, stress levels and medication prevent our body from recovering

    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.

  3. Chronic inflammatory systemic diseases: An evolutionary trade-off between acutely beneficial but chronically harmful programs.

    Straub, Rainer H; Schradin, Carsten

    2016-01-01

    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

    Full Text Available Long chain fatty acids influence inflammation through a variety of mechanisms; many of these are mediated by, or at least associated with, changes in fatty acid composition of cell membranes. Changes in these compositions can modify membrane fluidity, cell signaling leading to altered gene expression, and the pattern of lipid mediator production. Cell involved in the inflammatory response are typically rich in the n-6 fatty acid arachidonic acid, but the contents of arachidonic acid and of the n-3 fatty acids eicosapentaenoic acid (EPA and docosahexaenoic acid (DHA can be altered through oral administration of EPA and DHA. Eicosanoids produced from arachidonic acid have roles in inflammation. EPA also gives rise to eicosanoids and these often have differing properties from those of arachidonic acid-derived eicosanoids. EPA and DHA give rise to newly discovered resolvins which are anti-inflammatory and inflammation resolving. Increased membrane content of EPA and DHA (and decreased arachidonic acid content results in a changed pattern of production of eicosanoids and resolvins. Changing the fatty acid composition of cells involved in the inflammatory response also affects production of peptide mediators of inflammation (adhesion molecules, cytokines etc.. Thus, the fatty acid composition of cells involved in the inflammatory response influences their function; the contents of arachidonic acid, EPA and DHA appear to be especially important. The anti-inflammatory effects of marine n-3 PUFAs suggest that they may be useful as therapeutic agents in disorders with an inflammatory component.

    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.

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

    Directory of Open Access Journals (Sweden)

    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.

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

    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

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

    Directory of Open Access Journals (Sweden)

    Brodie eMiles

    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.

    Full Text Available BACKGROUND: There is a prevalence increase of overweight and obesity in Indonesia. Central obesity can lead a variety of chronic diseases through the inflammatory process. There are some markers for low-grade chronic inflammatory, such as cathepsin S, high sensitivity C-reactive protein (hs-CRP, interleukin-1- beta (IL-1β. To our current interest that central obesity can lead to various chronic diseases through the inflammatory process, we conducted a study to investigate correlation of Cathepsin S, hs-CRP, IL-1β in men with central obesity. METHODS: A cross-sectional study was conducted. Seventy-eight selected subjects were examined to collect anthropometric data and prepared for sample collection. Collected samples were processed for the following biochemical analyses: fasting glucose, high density lipoprotein (HDL-cholesterol, triglyceride, serum glutamic oxaloacetic transaminase (SGOT, serum glutamate pyruvate transaminase (SGPT, cathepsin S, hs-CRP, and IL-1β. Data distribution and variable correlation were then statistically analyzed. RESULTS: There were significant correlations between waist circumference (WC and cathepsin S (p=0.030; r=0.214, hs-CRP and cathepsin S (p=0.007; r=0.276, triglyceride and IL-1β (p=0.019; r=-0.235, WC and systolic blood pressure (SBP (p=0.003; r=-0.312, WC and fasting glucose (p=0.000; r=0.380, WC and body mass index (BMI (p=0.000; r=0.708. CONCLUSIONS: Our study showed that cathepsin S was correlated with central obesity, suggesting that cathepsin S could be a potential inflammatory marker in central obesity in the future.

  3. 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.

    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.

    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.

    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

    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.

    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.

    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.

    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

    2016-01-01

    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.

    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.

    We report a case of pericarditis and chronic inflammatory demyelinating polyneuropathy with biological signs of a lupus-like syndrome due to pegylated interferon alfa-2a therapy during treatment for chronic hepatitis C. The patient developed moderate weakness in the lower limbs and dyspnea. He was hospitalized for congestive heart failure. An electrocardiogram showed gradual ST-segment elevation in leads V(1) through V(6) without coronary artery disease. A transthoracic cardiac ultrasonographic study revealed moderate pericardial effusion with normal left ventricular function. Anti-DNA antibody and antids DNA IgM were positive. Neurological examination revealed a symmetrical predominantly sensory polyneuropathy with impairment of light touch and pin prick in globe and stoking-like distribution. Treatment with prednisolone improved the pericarditis and motor nerve disturbance and the treatment with intravenous immunoglobulin improved the sensory nerve disturbance. PMID:21161021

    The respiratory epithelium plays a critical role for the maintenance of airway integrity and defense against inhaled particles. Physical barrier provided by apical junctions and mucociliary clearance clears inhaled pathogens, allergens or toxics, to prevent continuous stimulation of adaptive immune responses. The "chemical barrier", consisting of several anti-microbial factors such as lysozyme and lactoferrin, constitutes another protective mechanism of the mucosae against external aggressions before adaptive immune response starts. The reconstruction of damaged respiratory epithelium is crucial to restore this barrier. This review examines the role of the airway epithelium through recent advances in health and chronic inflammatory diseases in the lower conducting airways (in asthma and chronic obstructive pulmonary disease). Better understanding of normal and altered epithelial functions continuously provides new insights into the physiopathology of chronic airway diseases and should help to identify new epithelial-targeted therapies.

    International Nuclear Information System (INIS)

    Objective: To investigate the relationship between changes of serum contents of CRP, IL-6, TNF-α, IL-10 and the development of complications (anemia, malnutrition, atherosclerosis) in patients with chronic renal failure. Methods: Serum IL-6, TNF-α (with RIA) and CRP, IL-10 (with ELISA) levels were determined in 126 patients with chronic renal failure and 36 controls. Blood hemoglobin, albumin, glucose and triglycerides levels were also determined in all these patients. Echocardiography was performed in 95 patients. Results: (1) Serum contents of CRP, IL-6, TNF-α and IL-10 were all significantly higher in the patients than those in the controls (P6mmol/L, n=83) were significantly higher than those in the corresponding patients without anemia, malnutrition and hyperglycemia ( all P 1.71mmol/L, n=68), the levels were lower than those in patients without high TG (P<0.001 for IL-6, P<0.01 for CRP and IL-10). In patients with aortic arteriosclerosis shown on echocardiography (n=37), levels of the markers were higher than those in patients without arteriosclerosis (n=58) (P<0.001 for IL-10, P<0.001 for CRP and IL-6, P<0.05 for TNF-α). Correlation studies showed that levels of all the four markers were negatively correlated with levels of hemoglobin and albumin, TNF-α levels were correlated with levels of glucose and CRP, IL-6, IL-10 levels were negatively correlated with triglyceride levels. (3) Levels of each of the pro-inflammatory markers (CRP, IL-6, TNF-α) were correlated with levels of the anti-inflammatory cytokine IL-10 (r=0.463, 0.546 and 0.402 respectively). Conclusion: (1) Serum levels of CRP, IL-6, TNF-α and IL-10 were increased in patients with chronic renal failure. (2) Levels of these markers were correlated in some degree with the development of complications (anemia, malnutrition, arteriosclerosis......) in the patients. (3) Levels of pro-inflammatory markers were correlated with levels of anti-inflammatory cytokine IL-10. (authors)

    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.

    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.

    Wu, Dawei; Zhang, Min; Song, Qian

    2015-08-01

    Chronic rhinosinusitis with nasal polyps (CRSwNP) and asthma is a common clinical refractory airway disease. Comprehensive treatment of nasal endoscopic surgery including nasal endoscopic surgery and medication, which can significantly improve nose-pulmonary symptoms and make sinusitis and asthma easier to be controlled by medication, has certain superiority. But the existence of disease heterogeneity of CRSwNP with asthma causes different reactions to the current treatment, which manifests as parts of polyps and asthma easy to recur and difficult to control. According to the research recently, the study of the heterogeneity of airway diseases, for example endotype, is a hot area of research. Endotype is a subtype of a condition, which is defined by a distinct functional or pathobiological mechanism. This is distinct from a phenotype, which is any observable characteristic or trait of a disease. Different Inflammatory subtypes often represent different pathophysiology and even different pathogenesis. The concept of inflammatory subtypes of airway diseases provides a new perspective for studies of airway diseases of endotype and the mechanism of combined airway diseases. This review summarizes recent advances in the clinical characterization and treatment of the CRSwNP with asthma. On this basis, we analyze and summarize the heterogeneity of CRSwNP and asthma separately from the perspective of inflammatory subtypes. Then according to the concept of the combined airway diseases and the common pathogenesis, we put forward the definition of inflammatory subtypes of the CRSwNP with asthma and preliminarily discuss the method of the definition.

    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

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.

    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.

    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.

    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.

    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.

    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

    Chronic ulcers represent a major health burden in our society. Despite many available therapies, a large number of ulcers do not heal. Protein based therapies fail in part due to proteolytic activity in the chronic wound bed. The aim of this in vitro study was to determine whether typical inflammatory cytokines and human salivary histatins remain stable when incubated with chronic wound extracts. Furthermore we determined whether a short exposure of histatins or cytokines was sufficient to exert long term effects on fibroblast migration. Stability of human recombinant cytokines IL-6 and CXCL8, and histatin variants (Hst1, Hst2, cyclic Hst1, minimal active domain of Hst1) in the presence of chronic wound extracts isolated from non-healing ulcers, was monitored by capillary zone electrophoresis. Migration-stimulating activity was assessed using a dermal fibroblast wound healing scratch assay. Histatins and cytokines stayed stable in saline for > 24h at 37°C, making them ideal as an off-the-shelf product. However, incubation with chronic wound extracts resulted in serious breakdown of Hst1 and Hst2 (~50% in 8h) and to lesser extent cyclic Hst1 and the minimal active domain of Hst1 (~20% in 8h). The cytokines IL-6 and CXCL8 were more stable in chronic wound extracts (~40% degradation in 96h). An initial 8-hour pulse of histatins or cytokines during a 96-hour study period was sufficient to stimulate fibroblast migration equally well as a continuous 96-hour exposure, indicating that they may possibly be used as novel bioactive therapeutics, exerting their activity for up to four days after a single exposure.

    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.

    Chronic pain is categorized as inflammatory and neuropathic, and there are common mechanisms underlying the generation of each pain state. Such pain is difficult to treat and the treatment at present is inadequate. Corydalis yanhusuo is a traditional Chinese medicine with demonstrated analgesic efficacy in humans. The potential antihyperalgesic effect of its active component is L-tetrahydropalmatine (L-THP). L-THP has been used for the treatment of headache and other mild pain. However, little is known about its analgesic effect on chronic pain and its mechanism. Here, we report that L-THP exerts remarkable antihyperalgesic effects on neuropathic and inflammatory pain in animal models. Neuropathic hypersensitivity was induced by segmental spinal nerve ligation and inflammatory hypersensitivity was induced by an intraplantar injection of complete Freund's adjuvant. To determine the receptor mechanism underlying the antihyperalgesic actions of L-THP, we used SCH23390, an antagonist of a dopamine D1 receptor, in an attempt to block the antihyperalgesic effects of L-THP. We found that L-THP (1-4 mg/kg, i.p.) produced a dose-dependent antihyperalgesic effect in spinal nerve ligation and complete Freund's adjuvant models. The antihyperalgesic effects of L-THP were abolished by a dopamine D1 receptor antagonist SCH23390 (0.02 mg/kg). Furthermore, L-THP (4 mg/kg, i.p.) did not influence motor function. These findings suggest that L-THP may ameliorate mechanical hyperalgesia by enhancing dopamine D1 receptor-mediated dopaminergic transmission. PMID:26981712

    Full Text Available Little is known about airway inflammatory markers in chronic obstructive pulmonary disease (COPD. The objective of the present study was to identify and try to correlate pulmonary and peripheral blood inflammatory markers in COPD. In a cross-sectional study on patients with stable COPD, induced sputum and blood samples were collected for the determination of C-reactive protein, eosinophilic cationic protein, serum amyloid A protein, a-1 antitrypsin (a-1AT, and neutrophil elastase. Twenty-two patients were divided into two groups according to post-bronchodilator forced expiratory volume in the first second (%FEV1: group 1 (N = 12, FEV1 <40% and group 2 (N = 10, FEV1 ³40%. An increase in serum elastase, eosinophilic cationic protein and a-1AT was observed in serum markers in both groups. Cytology revealed the same total number of cells in groups 1 and 2. There was a significantly higher number of neutrophils in group 1 compared to group 2 (P < 0.05. No difference in eosinophils or macrophages was observed between groups. Serum elastase was positively correlated with serum a-1AT (group 1, r = 0.81, P < 0.002 and group 2, r = 0.83, P < 0.17 and negatively correlated with FEV1 (r = -0.85, P < 0.03 and -0.14, P < 0.85, respectively. The results indicate the presence of chronic and persistent pulmonary inflammation in stable patients with COPD. Induced sputum permitted the demonstration of the existence of a subpopulation of cells in which neutrophils predominated. The serum concentration of all inflammatory markers did not correlate with the pulmonary functional impairment.

    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

    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.

    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 intrauterine inflammatory response after AI than normal mares (CIT, 24.4 ± 3.56, FLU, 0), but NO concentrations did not differ (P > 0.05) between categories of mares. In treated cycles with PRP, the intrauterine inflammatory response decrease (P intrauterine fluid. PMID:27020400

    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.

    Directory of Open Access Journals (Sweden)

    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.

    Almost all cell types release extracellular vesicles (EVs), which are derived either from multivesicular bodies or from the plasma membrane. EVs contain a subset of proteins, lipids, and nucleic acids from the cell from which they are derived. EV factors, particularly small RNAs such as miRNAs, likely play important roles in cell-to-cell communication both locally and systemically. Most of the functions associated with EVs are in the regulation of immune responses to pathogens and cancer, as well as in regulating autoimmunity. This Review will focus on the different modes of immune regulation, both direct and indirect, by EVs. The therapeutic utility of EVs for the regulation of immune responses will also be discussed.

    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. 

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

    2014-01-01

    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 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.

    The aetiology of the chronic inflammatory bowel diseases-ulcerative colitis and Crohn's disease-as well as 'microscopic colitis'-both collagenous (COC) and lymphocytic colitis (LC)-remains unknown. Autoimmune mechanisms, cytokine polymorphism, commensal bacteria, infectious agents and vascular...... impairment have all been proposed as playing important roles in the pathogenesis of this spectrum of diseases. A variety of proinflammatory mediators, including tumour necrosis factor alpha, interleukin-1beta, interferon gamma, leukotriene B4 and platelet activating factor, promote the adherence of...... generation of superoxide with reduced L-arginine availability. In active ulcerative colitis, and to a lesser extent in Crohn's disease, a greatly increased production of NO has been demonstrated by indirect and direct measurements. Surprisingly, even higher rates of production have been observed in COC...

    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.

    Full Text Available Abstract Background Candidate compounds being developed to treat chronic obstructive pulmonary disease are typically assessed using either acute or chronic mouse smoking models; however, in both systems compounds have almost always been administered prophylactically. Our aim was to determine whether the prophylactic effects of reference anti-inflammatory compounds in acute mouse smoking models reflected their therapeutic effects in (more clinically relevant chronic systems. Methods To do this, we started by examining the type of inflammatory cell infiltrate which occurred after acute (3 days or chronic (12 weeks cigarette smoke exposure (CSE using female, C57BL/6 mice (n = 7-10. To compare the effects of anti-inflammatory compounds in these models, mice were exposed to either 3 days of CSE concomitant with compound dosing or 14 weeks of CSE with dosing beginning after week 12. Budesonide (1 mg kg-1; i.n., q.d., roflumilast (3 mg kg-1; p.o., q.d. and fluvastatin (2 mg kg-1; p.o., b.i.d. were dosed 1 h before (and 5 h after for fluvastatin CSE. These dose levels were selected because they have previously been shown to be efficacious in mouse models of lung inflammation. Bronchoalveolar lavage fluid (BALF leukocyte number was the primary endpoint in both models as this is also a primary endpoint in early clinical studies. Results To start, we confirmed that the inflammatory phenotypes were different after acute (3 days versus chronic (12 weeks CSE. The inflammation in the acute systems was predominantly neutrophilic, while in the more chronic CSE systems BALF neutrophils (PMNs, macrophage and lymphocyte numbers were all increased (p Conclusions These results demonstrate that the acute, prophylactic systems can be used to identify compounds with therapeutic potential, but may not predict a compound's efficacy in chronic smoke exposure models.

  6. Chemokines and their receptors in the allergic airway inflammatory process.

    Science.gov (United States)

    Velazquez, Juan Raymundo; Teran, Luis Manuel

    2011-08-01

    The development of the allergic airway disease conveys several cell types, such as T-cells, eosinophils, mast cells, and dendritic cells, which act in a special and temporal synchronization. Cellular mobilization and its complex interactions are coordinated by a broad range of bioactive mediators known as chemokines. These molecules are an increasing family of small proteins with common structural motifs and play an important role in the recruitment and cell activation of both leukocytes and resident cells at the allergic inflammatory site via their receptors. Trafficking and recruitment of cell populations with specific chemokines receptors assure the presence of reactive allergen-specific T-cells in the lung, and therefore the establishment of an allergic inflammatory process. Different approaches directed against chemokines receptors have been developed during the last decades with promising therapeutic results in the treatment of asthma. In this review we explore the role of the chemokines and chemokine receptors in allergy and asthma and discuss their potential as targets for therapy. PMID:20352527

    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

    Ionizing radiation is able to elicit an anti-inflammatory, as well as a pro-inflammatory response. The anti-inflammatory effect of low radiation doses is successfully used within the scope of radon therapy to treat chronic inflammatory conditions such as Morbus Bechterew. In contrast, high radiation doses elicit a pro-inflammatory response which plays a role in normal tissue injury occurring after tumor therapy. The mechanisms underlying those differential effects are not fully understood and...

    In this study, the extent to which the scaffold architecture of polyglycerol sulfates affects inflammatory processes and hemocompatibility is investigated. Competitive L-selectin binding assays, cellular uptake studies, and blood compatibility readouts are done to evaluate distinct biological properties. Fully glycerol based hyperbranched polyglycerol architectures are obtained by either homopolymerization of glycidol (60% branching) or a new copolymerization strategy of glycidol with ethoxyethyl glycidyl ether. Two polyglycerols with 24 and 42% degree of branching (DB) are synthesized by using different monomer feed ratios. A perfectly branched polyglycerol dendrimer is synthesized according to an iterative two-step protocol based on allylation of the alcohol and subsequent catalytic dihydroxylation. All the polyglycerol sulfates are synthesized with a comparable molecular weight and degree of sulfation. The DB make the different polymer conjugates perform different ways. The optimal DB is 60% in all biological assays. PMID:24446246

    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.

    The study was carried out to analyze morphology of biofilm of periodontium and to develop electronic microscopic criteria of differentiated diagnostic of inflammatory diseases of gums. The scanning electronic microscopy was applied to analyze samples of bioflm of periodont from 70 patients. Including ten patients with every nosologic form of groups with chronic catarrhal periodontitis. of light, mean and severe degree, chronic catarrhal gingivitis, Candida-associated paroperiodontitis and 20 healthy persons with intact periodontium. The analysis was implemented using dual-beam scanning electronic microscope Quanta 200 3D (FEI company, USA) and walk-through electronic micJEM 100B (JEOL, Japan). To detect marker DNA of periodont pathogenic bacteria in analyzed samples the kit of reagentsfor polymerase chain reaction "MultiDent-5" ("GenLab", Russia). The scanning electronic microscopy in combination with transmission electronic microscopy and polymerase chain reaction permits analyzing structure, composition and degree of development of biofilm of periodontium and to apply differentiated diagnostic of different nosologic forms of inflammatory diseases of periodontium, including light form of chronic periodontitis and gingivitis. The electronic microscopical indications of diseases ofperiodontium of inflammatory character are established: catarrhal gingivitis, (coccal morphological alternate), chronic periodontitis (bacillary morphological alternate), Candida-associated periodontitis (Candida morphological alternate of biofilm ofperiodontium).

  13. Diagnostic value of 'in vitro' and 'in vivo' labelled leucocytes in patients with inflammatory processes

    International Nuclear Information System (INIS)

    A comparison of two leucocyte scanning techniques: 'in vitro' with 99mTc-HMPAO and 'in vivo' with 99mTc-MAb 250/183 is carried out. A total of 34 patients with bowel, bone and joint inflammations were examined simultaneously by both methods. The results for the in vitro method indicate 90.1% sensitivity, 100.0% specificity and 94.1% accuracy, and for the 'in vivo' method the values are 86.4%, 91.7%, 88.2%, respectively. It is concluded the less traumatic 'in vivo' method is more suitable for patients with unclear localization of the inflammatory process, seriously ill or children, while in chronic disease or in cases with known inflammation focus the 'in vitro' method is recommended because of the better quality of the images. 5 refs., 2 tabs., 2 figs.

  14. Visualization of inflammatory processes using in vitro and in vivo labelled leucocytes

    International Nuclear Information System (INIS)

    Radionuclide labelled leukocytes are used as a method of choice in demonstrating a variety of active inflammatory process and abscesses. It is the purpose of this study to evaluate the in vivo and in vitro methods for leucocyte labelling. A total of 124 patients with inflammatory lesions are studied. In 95 of them the in vitro method with 99mTc-HMPAO or 111In-oxine labelling is applied, in 29 - the in vivo method with 99mTc-Mab (BW 250/183), and in 10 - a combination of both methods. The following values for the main characteristics of the methods are found: 1) for in vitro method: sensitivity - 86.4%, specificity - 96.6% and accuracy -91.2%; 2) for in vivo method: sensitivity - 83.3%, specificity - 93.8% and accuracy - 86.2%. It is assumed that in serious case and when prompt diagnosis is required, the use of the easier-to-use in vivo method is indicated, whereas in processes which are chronic or with obscure localization, the in vitro method is more suitable since it may possibly yield a leucocyte scan of a higher quality. 5 refs., 4 figs., 2 tabs.

    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.

    Science.gov (United States)

    Ledford, Dennis K; Lockey, Richard F

    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

    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.

  19. 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)

    Chronic wounds are presumed to persist in the inflammatory state, preventing healing. Emerging evidence indicates a clinical impact of bacterial biofilms in soft tissues, including Pseudomonas aeruginosa (PA) biofilms. To further investigate this, we developed a chronic PA biofilm wound infection...... model in C3H/HeN and BALB/c mice. The chronic wound was established by an injection of seaweed alginate-embedded P. aeruginosa PAO1 beneath a third-degree thermal lesion providing full thickness skin necrosis, as in human chronic wounds. Cultures revealed growth of PA, and both alginate with or without...... PAO1 generated a polymorphonuclear-dominated inflammation early after infection. However, both at days 4 and 7, there were a more acute polymorphonuclear-dominated and higher degree of inflammation in the PAO1 containing group (p <0.05). Furthermore, PNA-FISH and supplemented DAPI staining showed...

    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.

    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.

  3. Diffusion tensor imaging of peripheral nerve in patients with chronic inflammatory demyelinating polyradiculoneuropathy: a feasibility study

    International Nuclear Information System (INIS)

    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.)

    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.

  6. Visualization of inflammatory processes using 'in vitro' and in vivo' labelled leucocytes

    International Nuclear Information System (INIS)

    The labelled leucocytes have become a means of choice for the diagnosis of a variety of active inflammatory conditions. The aim of the study was to evaluate 'in vivo' and 'in vitro' methods for labelling of leucocytes. A total of 146 patients, suspected of having various inflammatory lesions were examined. In 95 of them 'in vitro' method with 99mTc-HMPAO or 111In-oxine was used, in 29 'in vivo' method with 99mTc-MAB (BW 250/183) and in 22 both methods. The obtained results of sensitivity, specificity and accuracy were 87,3%, 96,5%, 89,5% for 'in vitro' method and 83,3%, 93,8%, 86,2% for 'in vivo' method. Taking into consideration the received data and comparable results, we think that in seriously ill patients and in cases of urgency, the use of easier 'in vivo' method is more suitable, while in chronic processes or in such with unclear localisation, 'in vitro' method is recommended, which sometimes gives images with better quality.

    Full Text Available Abstract Background Chronic pancreatitis is characterized by progressive fibrosis, pain and loss of exocrine and endocrine functions. The long-standing chronic pancreatitis and its associated pancreatic fibrosis are the most common pathogenic events involved in human pancreatic carcinogenesis, but the therapeutic strategies to chronic pancreatitis and the chemoprevention of pancreatic carcinogenesis are very limited. Methods We investigated the effect of sulindac, a non-steroidal anti-inflammatory drug (NSAID, on inhibition of chronic pancreatitis in a caerulein induced chronic pancreatitis mouse model. Results Sulindac significantly reduced the severity of chronic pancreatitis including the extent of acini loss, inflammatory cell infiltration and stromal fibrosis. The protein expression of phosphorylation of MEK/ERK was inhibited in the chronic pancreatic tissues by sulindac treatment as measured by Western blot assay. The levels of inflammatory cytokines including TNF-α and MCP-1 were also significantly decreased with sulindac treatment, as well as the expression of TGF-β, PDGF-β, SHH and Gli in the chronic pancreatic tissue detected by qPCR assay and confirmed by western blot assay. The activation of pancreatic satellet cells was also inhibited by sulindac as measured by the activity of α-smooth muscle actin (α-SMA in the pancreatic tissue of chronic pancreatitis. Conclusions Sulindac is a promising reagent for the treatment of chronic pancreatitis via inhibition of inflammatory cell infiltration and stromal fibrosis, the inhibitory effect of sulindac on chronic pancreatitis may through targeting the activation ERK/MAPK signaling pathway.

    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

    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.

  10. 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.

    2008-04-01

    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.

    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.

    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.

    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.)

    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 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.

  14. Positron emission tomography/computed tomography in the diagnosis of inflammatory processes

    International Nuclear Information System (INIS)

    The hybrid imaging modality known as PET/CT is being continuously introduced as a method of choice in the diagnostics of numerous inflammatory processes. The dual - computer tomography/positron emission tomography -investigation has advantages over other imaging modalities, mainly because of its ability to provide both morphological and functional information - combined in a whole body scan. Most of the inflammatory processes require on-time, accurate diagnostics and an imaging method that can provide therapy monitoring. The purpose of the following literature review is to compare the clinical application of PET/CT to other imaging modalities investigating inflammatory processes and to show its important role in the diagnostic algorithm and follow up of many inflammatory processes such as fever of unknown origin, osteomyelitis, inflammation of vascular prostheses etc. (authors) Key words: 18F-FDG PET/CT.

    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.

  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.

    Trigeminal nerve stimulation (TNS) has recently been demonstrated effective in the treatment of epilepsy and mood disorders. Here, we aim to determine the effects of TNS on epileptogenesis, cognitive function, and the associated hippocampal apoptosis and inflammatory responses. Rats were injected with pilocarpine to produce status epilepticus (SE) and the following chronic epilepsy. After SE induction, TNS treatment was conducted for 4 consecutive weeks. A pilocarpine re-injection was then used to induce a seizure in the epileptic rats. The hippocampal neuronal apoptosis induced by seizure was assessed by TUNEL staining and inflammatory responses by immunohistochemistry and enzyme-linked immunosorbent assay (ELISA). The spontaneous recurrent seizure (SRS) number was counted through video monitoring, and the cognitive function assessed through Morris Water Maze (MWM) test. TNS treatment attenuated the SRS attacks and improved the cognitive impairment in epileptic rats. A pilocarpine re-injection resulted in less hippocampal neuronal apoptosis and reduced level of interleukin-1 beta (IL-1β), tumor necrosis factor-α (TNF-α), and microglial activation in epileptic rats with TNS treatment in comparison to the epileptic rats without TNS treatment. It is concluded that TNS treatment shortly after SE not only protected against the chronic spontaneous seizures but also improved cognitive impairments. These antiepileptic properties of TNS may be related to its attenuating effects on hippocampal apoptosis and pro-inflammatory responses. PMID:26973056

    Small peptides patterned after the N terminus of the synaptosomal protein of 25 kDa, a member of the protein complex implicated in Ca(2+)-dependent neuronal exocytosis, inhibit in vitro the release of neuromodulators involved in pain signaling, suggesting an in vivo analgesic activity. Here, we report that compound DD04107 (palmitoyl-EEMQRR-NH(2)), a 6-mer palmitoylated peptide that blocks the inflammatory recruitment of ion channels to the plasma membrane of nociceptors and the release of calcitonin gene-related peptide from primary sensory neurons, displays potent and long-lasting in vivo antihyperalgesia and antiallodynia in chronic models of inflammatory and neuropathic pain, such as the complete Freund's adjuvant, osteosarcoma, chemotherapy, and diabetic neuropathic models. Subcutaneous administration of the peptide produced a dose-dependent antihyperalgesic and antiallodynic activity that lasted ≥24 h. The compound showed a systemic distribution, characterized by a bicompartmental pharmacokinetic profile. Safety pharmacology studies indicated that the peptide is largely devoid of side effects and substantiated that the in vivo activity is not caused by locomotor impairment. Therefore, DD04107 is a potent and long-lasting antinociceptive compound that displays a safe pharmacological profile. These findings support the notion that neuronal exocytosis of receptors and neuronal algogens pivotally contribute to chronic inflammatory and neuropathic pain and imply a central role of peptidergic nociceptor sensitization to the pathogenesis of pain.

    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.

    The immunologic characterization of chronic idiopathic urticaria (CIU), mainly regarding cytokine profile needs more investigation. We examined circulating inflammatory cytokine levels, T-cell induced secretion, and cytokine mRNA expression in patients with CIU subjected to the intradermal autologous serum skin test (ASST). Increased levels of circulating pro-inflammatory cytokines, such as TNF-alpha, IL-1beta, IL-12p70, and IL-6 have been observed in most of patients with CIU, together with an enhancement of IL-2 secretion following T-cell stimulation. Highlighting the inflammatory profile in CIU found in ASST positive, is the enhanced B-cell proliferative responsiveness and increased IL-17 secretion levels. ASST-positive patients also exhibited impaired IL-4 secretion associated with increased IL-10 production. Altered cytokine expression in patients with ASST-negative, was the down-modulation of spontaneous IL-10 mRNA expression levels in peripheral blood mononuclear cells. Our findings support the concept of immunologic dysregulation in CIU, revealing a systemic inflammatory profile associated with disturbed cytokine production by T cells, mainly related to IL-17 and IL-10 production.

    Cytokines are inflammatory messengers that orchestrate the brain's response to immunological challenges, as well as possibly even toxic and psychological insults. We previously reported that genetic ablation of the pro-inflammatory cytokine, interferon-gamma (IFN-γ), attenuated some of the corticosteroid, cytokine, and limbic dopaminergic variations induced by 6 weeks of exposure to an unpredictable psychologically relevant stressor. Presently, we sought to determine whether a lack of IFN-γ would likewise modify the impact of chronic stress on hippocampus-dependent memory function and related neurotransmitter and neurotrophin signaling systems. As predicted, chronic stress impaired spatial recognition memory (Y-maze task) in the wild-type animals. In contrast, though the IFN-γ knockouts (KOs) showed memory disturbances in the basal state, under conditions of chronic stress these mice actually exhibited facilitated memory performance. Paralleling these findings, while overall the KOs displayed altered noradrenergic and/or serotonergic activity in the hippocampus and locus coeruleus, norepinephrine utilization in both of these memory-related brain regions was selectively increased among the chronically stressed KOs. However, contrary to our expectations, neither IFN-γ deletion nor chronic stressor exposure significantly affected nucleus accumbens dopaminergic neurotransmission or hippocampal brain-derived neurotrophic factor protein expression. These findings add to a growing body of evidence implicating cytokines in the often differential regulation of neurobehavioral processes in health and disease. Whereas in the basal state IFN-γ appears to be involved in sustaining memory function and the activity of related brain monoamine systems, in the face of ongoing psychologically relevant stress the cytokine may, in fact, act to restrict potentially adaptive central noradrenergic and spatial memory responses.

    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.

    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

    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 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.

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. PMID:27445627

    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

    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.

    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.

    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

    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.

  4. Roles of inflammatory caspases during processing of zebrafish interleukin-1β in Francisella noatunensis infection

    The interleukin-1 family of cytokines are essential for the control of pathogenic microbes but are also responsible for devastating autoimmune pathologies. Consequently, tight regulation of inflammatory processes is essential for maintaining homeostasis. In mammals, interleukin-1 beta (IL-1β) is primarily regulated at two levels, transcription and processing. The main pathway for processing IL-1β is the inflammasome, a multiprotein complex that forms in the cytosol and which results in the activation of inflammatory caspase (caspase 1) and the subsequent cleavage and secretion of active IL-1β. Although zebrafish encode orthologs of IL-1β and inflammatory caspases, the processing of IL-1β by activated caspase(s) has never been examined. Here, we demonstrate that in response to infection with the fish-specific bacterial pathogen Francisella noatunensis, primary leukocytes from adult zebrafish display caspase-1-like activity that results in IL-1β processing. Addition of caspase 1 or pancaspase inhibitors considerably abrogates IL-1β processing. As in mammals, this processing event is concurrent with the secretion of cleaved IL-1β into the culture medium. Furthermore, two putative zebrafish inflammatory caspase orthologs, caspase A and caspase B, are both able to cleave IL-1β, but with different specificities. These results represent the first demonstration of processing and secretion of zebrafish IL-1β in response to a pathogen, contributing to our understanding of the evolutionary processes governing the regulation of inflammation.

    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

    International Nuclear Information System (INIS)

    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

    While cannabinoid receptor agonists have analgesic activity in chronic pain states, they produce a spectrum of central CB1 receptor-mediated motor and psychotropic side effects. The actions of endocannabinoids, such as anandamide are terminated by removal from the extracellular space, then subsequent enzymatic degradation by fatty-acid amide hydrolase (FAAH). In the present study, we compared the effect of a selective FAAH inhibitor, URB597, to that of a pan-cannabinoid receptor agonist HU210...

    Defensins are endogenous antimicrobial peptides with a broad activity spectrum. Even at micromolar concentrations gramnegative and grampositive bacteria, but also mycobacteria, as well as fungi (candida), viruses (herpes) and protozoa (giardia lamblia) are destroyed. As part of the innate immune system defensins are expressed by the intestinal epithelium and contribute to the maintenance of the mucosal barrier. This barrier appears to be defective in inflammatory bowel diseases since on one hand, the immune response is directed against the "normal" luminal bacterial flora and on the other hand, mucosal adherent and invasive bacteria have been observed in these diseases. A defective defensin expression may well explain these phenomena. Indeed, Crohn's disease of the terminal ileum, especially if associated with a NOD2 mutation, is characterised by a diminished alpha-defensin (human defensin 5 and 6) expression, and in inflamed Crohn's colitis, in contrast to ulcerative colitis, the beta-defensin (human beta-defensins 2 and 3) response is reduced. Through a deficient chemical mucosal barrier this defect could lead to increased bacterial invasion into the intestinal mucosa and might well explain an adequate inflammatory response. Although the final proof that this deficient defensin response leads to a reduced antibacterial activity of the intestinal mucosa is still lacking, the most plausible concept of pathogenesis of Crohn's disease is a defensin deficiency syndrome.

    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.

  9. Diagnostic evaluation of chronic inflammatory intestinal diseases in children and adolescents: MRI with true-FISP as new gold standard?

    International Nuclear Information System (INIS)

    Purpose: to evaluate the impact of magnetic resonance imaging (MRI) with use of True-FISP sequences in the evaluation of inflammatory bowel-wall changes in children and adolescents with Crohn's disease. Furthermore, the diagnostic procedure in children and adolescents with chronic inflammatory bowel disease (IBD) will be discussed in light of the relevant literature. Material and methods: twenty-four children and adolescents aged between 7 and 21 years with suspected or known IBD underwent MRI on a 1.5T-scanner (Philips ACS-NT, Best, Netherlands). One hour after 11 of a 2.5% mannitol solution was given orally, MR imaging was performed using coronal HASTE-M2D, coronal fat-suppressed T2-TSE, axial dynamic T1-weighted GE-sequences before and after i.v.-contrast material injection (0.1 mmol/kg Gd-DTPA) and using a 2D-balanced-FFE-sequence (True-FISP) before and after i.v.-contrast material injection in coronal and axial planes. The MR-images were correlated with endoscopy and the clinical findings. In 14 patients, a recently performed conventional radiographic enteroclysis was available. Each performed MRI sequence was evaluated by three experienced radiologists regarding the sensitivity and specificity of each sequence in the detection of inflammatory bowel wall changes. In addition, the image quality was assessed regarding the different tissue contrasts and the susceptibility to artifacts. The distension of the bowel wall and the patients' acceptance of the MRI examination were recorded. Results: with a sensitivity in detecting inflammatory small bowel changes of 93.3% (axial pre-contrast, coronal post-contrast) and 100% (axial post-contrast, coronal pre-contrast), the True-FISP outnumbers the other performed sequences (T1 = 80%, HASTE = 13.3% and T2-TSE = 53.3%). The difference between True-FISP and contrast-enhanced T1 was not statistically significant, whereas the difference between True-FISP and HASTE and T2-TSE, respectively. (orig.)

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.

    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

    2014-11-01

    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.

    2014-01-01

    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

    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.

    We previously demonstrated the safety and efficacy of fluoroquinolone-macrolide combination therapy in category Ⅱ chronic bacterial prostatitis (CBP).The aim of this study is to retrospectively compare the microbiological and clinical findings of two treatment schemes for CBP based on the combination of azithromycin (500 mg,thrice-weekly) with a once-daily 500-or 750-mg dose of ciprofloxacin (Cipro-500 or Cipro-750 cohort,respectively).Combined administration of azithromycin (1500 mg week-1) with ciprofloxacin at the rate of 750 mg day-1 for 4 weeks rather than at 500 mg day-1 for 6 weeks increased the eradication rates from 62.35% to 77.32% and the total bacteriological success from 71.76% to 85.57%.A significant decrease in pain and voiding signs/symptoms and a significant reduction in inflammatory leukocyte counts and serum prostate-specific antigen (PSA) were sustained throughout an 18-month follow-up period in both groups.Ejaculatory pain,haemospermia and premature ejaculation were significantly attenuated on microbiological eradication in both groups,but the latter subsided more promptly in the Cipro-750 cohort.In total,59 Cipro-750 patients showed mild-to-severn erectile dysfunction (ED) at baseline,while 22 patients had no ED on microbiological eradication and throughout the follow-up period.In conclusion fluoroquinolone-macrolide therapy resulted in pathogen eradication and CBP symptom attenuation,including pain,voiding disturbances and sexual dysfunction.A once-daily 750-mg dose of ciprofloxacin for 4 weeks showed enhanced eradication rates and lower inflammatory white blood cell counts compared to the 500-mg dose for 6 weeks.Our results are open to further prospective validation.

    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.

    The number of patients with dialysis-dependent renal failure has increased in the past years worldwide. Several parameters have been introduced for the quantitative assessment of dialysis adequacy. The National Cooperative Dialysis Study results indicated that Kt/V and time-averaged concentration of urea (TAC) are predictors of mortality in patients who receive maintenance hemodialysis (HD). Also, the protein catabolic ratio (PCR), which is an indicator of nutritional status, can predict patients' mortality. Our aim was to assess the impact of parameters that show dialysis adequacy on indices of nutrition or inflammation. A total of 46 patients were included in the study; eight patients were excluded during the course of the study and 38 patients were enrolled in the final analysis. All patients were receiving HD for at least for three months. HD was administered three times per week and the study lasted for two months. Kt/V, TAC and PCR were assessed at the beginning of the study based on patients' urea and blood urea nitrogen in the first week of our study; these calculations were repeated at the end of the first and second months using the mean of the mentioned values in the month. Both adequacy indices significantly and positively correlated with changes in PCR (P <0.001). However, no significant correlation was detectable between Kt/V and TAC with either body mass index and albumin or C-reactive protein. Based on the Kt/V values, patients with adequate dialysis had slower decrease in the PCR (P <0.001). Our results indicate that adequacy of dialysis is correlated with patients' nutritional status. No correlation was observed between dialysis adequacy and inflammatory status. PMID:26586053

    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.

    Roles of ionotropic purinergic (P2X) receptors in chronic pain have been intensively investigated. However, the contribution of metabotropic purinergic (P2Y) receptors to pathological pain is controversial. In the present study, using single cell RT-PCR (reverse transcription-polymerase chain reaction) and single cell nested-PCR techniques, we examined the expression of P2X(2), P2X(3), P2Y(1) and P2Y(2) mRNA transcripts in retrogradely labeled cutaneous sensory neurons from mouse lumber dorsal root ganglia (DRGs) following peripheral inflammation. The percentage of cutaneous sensory neurons expressing P2Y(2) mRNA transcripts increased after complete Freund's adjuvant (CFA) treatment. Particularly, the P2Y(2) mRNA transcripts were more frequently detected in small-diameter cutaneous neurons from CFA-treated mice than those from control mice. Coexpression of P2Y(2) and P2X (P2X(2) or P2X(3)) mRNAs was more frequently observed in cutaneous sensory neurons from CFA-treated mice relative to controls. Pain behavioral tests showed that the blockade of P2Y receptors by suramin attenuated mechanical allodynia evoked either by CFA or uridine triphosphate (UTP), an endogenous P2Y(2) and P2Y(4) agonist. These results suggest that chronic inflammatory pain enhances expression of P2Y(2) receptor in peripheral sensory neurons that innervate the injured tissue and the activation of P2Y receptors contributes to mechanical allodynia following inflammation.

    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.

    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.

    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

    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 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.

    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.

    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.

    Despite the described clear epigenetic effects of smoking, the effect of smoking on genome-wide gene expression in the blood is obscure. We therefore studied the smoking-induced changes in the gene-expression profile of the peripheral blood. RNA was extracted from the whole blood of 48 individuals with a detailed smoking history (24 never-smokers, 16 smokers, and 8 ex-smokers). Gene-expression profiles were evaluated with RNA sequencing, and results were analyzed separately in 24 men and 24 women. In the male smokers, 13 genes were statistically significantly (false-discovery rate <0.1) differentially expressed; in female smokers, 5 genes. Although most of the differentially expressed genes were different between the male and female smokers, the G-protein-coupled receptor 15 gene (GPR15) was differentially expressed in both male and female smokers compared with never-smokers. Analysis of GPR15 methylation identified significantly greater hypomethylation in smokers compared with that in never-smokers. GPR15 is the chemoattractant receptor that regulates T-cell migration and immunity. Up-regulation of GPR15 could explain to some extent the health hazards of smoking with regard to chronic inflammatory diseases. PMID:26348578

    Oral microbiota of the mouth is the most diverse microbial community in the human body and plays a decisive role in the emergence and evolution of gingival pathology, contributing as well to the host general health condition, based on complex interactions established between the microbial community members and the host. A specific shift in the quantity and diversity of the microbial community developed on dental and mucosal surfaces, could lead to the occurrence of chronic inflammation mediated by the overproduction of pro-inflammatory cytokines. The mechanical treatment and current medication efficiency for the periodontal disease is limited in time due to the rapid plaque forming. Also, the antimicrobial treatment is limited by the sessile growth of the microorganisms, resulting in a poor biofilm penetration by biocides or antibiotics. In line with that, the attention of the scientific community shifted to ethnopharmacology as a complementary, or alternative therapeutic option for fighting infections with resistant bacteria. The vegetal and bee products are an important source of bioactive compounds, acting as harmless antimicrobials and periodontal inflammation suppressors. Vegetable bioproducts have been proven to exhibit multiple antipathogenic effects, such as microbicidal activity, virulence attenuation, and synergistic effects between the components found in the complex vegetal matrixes, or with conventional biocides, as well as immunomodulatory effects. The purpose of this review is to highlight the importance of vegetable products as a possible complementary treatment for periodontitis and their potential for the development of innovative therapeutic strategies.

    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.

    novel drugs that target TNF-α signaling are still being developed. Indeed, blockade of this pathway seems so important amongst immune-targets that TNF-α targeted therapies will continue to have a significant role in the treatment of chronic inflammation. However, up to 40% of RA and IBD patients do 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...

    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

    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

  13. 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

    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

    Collagen makes up one third of the total protein in humans, being formed by the connection of three polypeptide chains arranged in a triple helix. This protein has fundamental importance in the formation of extracellular matrix of connective tissue. This study aimed to analyze the structural changes of collagen, which are resulting from inflammatory processes in oral mucosa, and to make the comparative analysis between the histopathology and the Raman spectra. The samples of tissues with inflammatory fibrous hyperplasia (IFH) and normal mucosa (NM) were evaluated by Raman Spectroscopy, hematoxylin-eosin and Massons trichrome stain. The histological analysis in both stains showed differences in collagen fibers, which was presented as thin fibers and arranged in parallel direction in NM and as collagen fibers are thick, mature and not organized, showing that these types of stain show morphological changes of collagen in IFH. The Raman Spectroscopy discriminate the groups of NM and IFH based on vibrational modes of proline, hydroxiproline and CH3, CH2. The histological stains only shows information from morphological data, and can be complemented by Raman spectra. This technique could demonstrate that inflammatory process caused some changes in collagen structure which is related to aminoacids such as proline and hidroxyproline.

  16. 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.

  18. 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

  19. Evaluation of MRI findings in non-specific inflammatory processes in the parasellar region

    International Nuclear Information System (INIS)

    We report the MRI findings on 6 patients with a non-specific inflammatory process in the parasellar region. Ophthalmoplegia developed in all patients. Only two patients complained of boring pain behind the eye and one of mild headache. The other three patients did not complain of pain. MRI clearly showed the extent of the lesions. In two patients the lesion was localized in the cavernous sinus. In the other patients, the lesions extended to the orbital apex, intrasellar and suprasellar regions, infratemporal fossa, or other neighboring regions beyond the cavernous sinus. The signal intensity of the lesions on T2WI was variable. The lesions were significantly enhanced after administration of Gd-DTPA. They were non-homogeneously enhanced in some patients. In three patients the lesions were well enhanced on the initial MRI scans. However, they were less enhanced on subsequent follow-up MRI or CT. The signal intensity and the degree of enhancement may vary substantially during the evolution of the inflammatory process or by blood flow in the cavernous sinus. Painful ophthalmoplegia is encountered in diseases of diverse pathogenesis in which the signal intensity and the extent of the lesions are variable. The MRI findings in one patient were not different from those of perineural spread from extracranial lesions, especially the one in the nasopharynx. However, MRI showed no abnormality in the nasopharynx and the base of the skull. In this patient, the clinical symptoms and MRI findings improved spontaneously. In some patients, the clinical symptoms and the extent of the pathological process were different from those in the classic Tolosa-Hunt syndrome. It could be suggested that the spectrum of non-specific inflammatory processes in the parasellar region is wider than the criteria for classic Tolosa-Hunt syndrome. (J.N.M.)

    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.

    Insulin-like growth factor-1 (IGF-1) is a neurotrophic factor and plays important roles in the nervous system. Increasing evidence supports that IGF-1 contributes to pain hypersensitivity through its insulin-like growth factor-1 receptor (IGF-1R) by activating IGF-1R/Akt or MAPK signaling pathways, whereas T-type Cav3.2 channel can facilitate and amplify pain signals originating from the sensory periphery. A recent study showed that activated IGF-1R can increase T-type Cav3.2 channel currents and further activate the G protein-dependent PKCα pathway to contribute to inflammatory pain sensitivity. However, the colocalization of IGF-1R and Cav3.2 in mouse dorsal root ganglion (DRG) under chronic inflammatory pain conditions remains elusive. In this study, we investigated changes in the expression of IGF-1R and the Cav3.2 channel, and their colocalization in mouse DRGs in chronic inflammatory pain condition (induced by complete Freund's adjuvant intraplanter injection) using real-time RT-PCR and immunohistochemistry approaches to confirm that Cav3.2 channel can mediate pain facilitation following IGF-1/IGF-1R signaling. We found that IGF-1R was expressed extensively in DRG neurons including small-, medium-, and large-sized neurons, whereas Cav3.2 channel was expressed exclusively in small-sized DRG neurons of naive mice. Expression of Cav3.2, but not IGF-1R, and colocalization of Cav3.2 and IGF-1R were increased in lumbar (L)4-L6 primary sensory neurons in DRGs of mice in chronic inflammatory pain. Moreover, the increased colocalization of IGF-1R and Cav3.2 is exclusively localized in small- and medium-sized primary sensory neurons. Our findings provided morphological evidence that T-type Cav3.2 channel, at least partially, mediates the pain facilitation of IGF-1/IGF-1R signaling in chronic inflammatory pain condition.

    Evaluation of leukocyte and nuclear indices of intoxication in dynamics in liquidators of the Chernobyl NPP consequences is brought in this work. It is demonstrated that the study of blood indices in complex with application of leukocyte and nuclear indices intoxication formulas gives an opportunity to fix changes in blood content at liquidators exposed to small doses not only in the early, but in late post-accidental period as well. It was revealed that inflammatory processes proceeded in liquidators in the first years of post-accidental period, have a stable character which is reflected on development of total morbidity

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).

    We have studied the response to intravenous immunoglobulins (IVIg) by a transcriptomic approach in 11 chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) patients (CIDP duration = 6 [0.83-6.5] years). RNA was extracted from cells in whole blood collected before and 3 weeks after IVIg treatment, and hybridized on Illumina chips. After RNA quality controls, gene expression was analyzed using statistical tests fitted for microarrays (R software, limma package), and a pathway analysis was performed using DAVID software. We identified 52 genes with expression that varied significantly after IVIg (fold change [FC] > 1.2, P CIDP pathophysiology and the response to IVIg. We conclude that responder patients have stronger inflammatory activity that is lessened by IVIg. PMID:27175635

    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

    Bifidobacteria have been reported to reduce inflammation and contribute to intestinal homeostasis. However, the interaction between these bacteria and the gut immune system remains largely unknown. Because of the central role played by dendritic cells (DCs) in immune responses, we examined in vitro the effects of a Bifidobacteria mixture (probiotic) on DC functionality from children with inflammatory bowel disease. DCs obtained from peripheral blood monocytes of patients with Crohn's disease (CD), ulcerative colitis, and noninflammatory bowel disease controls (HC) were incubated with fluorochrome-conjugated particles of Escherichia coli or DQ-Ovalbumin (DQ-OVA) after a pretreatment with the probiotic, to evaluate DC phenotype, antigen sampling and processing. Moreover, cell supernatants were collected to measure tumor necrosis factor alpha, interferon gamma, interleukin 17, and interleukin 10 production by enzyme-linked immunosorbent assay. DCs from CD children showed a higher bacteria particles uptake and DQ-OVA processing after incubation with the probiotic; in contrast, DC from both ulcerative colitis and HC showed no significant changes. Moreover, a marked tumor necrosis factor alpha release was observed in DC from CD after exposure to E. coli particles, whereas the probiotic did not affect the production of this proinflammatory cytokine. In conclusion, the Bifidobacteria significantly improved the antigen uptake and processing by DCs from patients with CD, which are known to present an impaired autophagic functionality, whereas, in DCs from ulcerative colitis and HC, no prominent effect of probiotic mixture was observed. This improvement of antigen sampling and processing could partially solve the impairment of intestinal innate immunity and reduce uncontrolled microorganism growth in the intestine of children with inflammatory bowel disease.

    A substantial proportion of patients with burn injury develop chronic itch, which can severely affect their quality of life. As found in research on chronic pain, different psychophysiological processes may also play a role in chronic itch, of which central sensitization, conditioned modulation, and attentional processes have been studied most frequently. This study aimed to explore psychophysiological processes of chronic post-burn itch by comparing 15 patients with long-term itch due to burn injury with 15 matched healthy controls. Exploratory results indicated tendencies for higher itch sensitivity in patients than in controls, for mechanical stimuli and histamine, but not for electrical stimulation. Results further suggest that the efficacy of itch modulation by an itch- or pain-conditioning stimulus or directing attention towards itch stimuli do not differ between these patients and controls. Further elucidation of the processes underlying post-burn itch may improve the early identification and treatment of burn patients developing chronic itch. PMID:26694745

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

    The objective of this study was to assess the influence of an asymptomatic experimental infection by Babesia bigemina on cholinesterase's as markers of the inflammatory process and biomarkers of oxidative imbalance. For this purpose, eight naive animals were used, as follows: four as controls or uninfected; and four infected with an attenuated strain of B. bigemina. Blood samples were collected on days 0, 7 and 11 post-inoculation (PI). Parasitemia was determined by blood smear evaluation, showing that the infection by B. bigemina resulted in mean 0.725 and 0.025% on day 7 and 11 PI, respectively, as well as mild anemia. The activities of acetylcholinesterase, butyrylcholinesterase and catalase were lower, while levels of thiobarbituric acid reactive substances and superoxide dismutase activity were higher in infected animals, when compared with the control group. This attenuated strain of B. bigemina induced an oxidative stress condition, as well as it reduces the cholinesterasés activity in infected and asymptomatic cattle. Therefore, this decrease of cholinesterase in infection by B. bigemina purpose is to inhibit inflammation, for thereby increasing acetylcholine levels, potent anti-inflammatory molecules.

    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.

  17. Is SPECT useful in imaging of abdominal inflammatory processes using 99mTc-HMPAO-WBCs?

    International Nuclear Information System (INIS)

    Aim: The aim of the study is to determine whether SPECT gives additional information in the assessment of inflammation of the abdominal region with labelled white blood cells as compared with usual planar imaging. Patients And Methods: SPECT and planar imaging was performed in 26 patients with suspected inflammatory process in the abdomen, within three hours after injection of autologous white blood cells labelled with 99m Tc HMPAO. Planar images where acquired as static spot images using high resolution low energy collimator on 256 x 256 matrix. SPECT was performed using the same collimator on 128 x 128 matrix in 128 projections. Filtered back projection was used for reconstruction and volume rendering was performed. Results: The lesions in the abdomen were classified as jejunum, colon ascendents, colon transversum, colon descendents, sigmoid, and lesions outside GIT. All lesions, which were seen on planar images, except one, were also seen on SPECT. Five equivocal lesions seen on planar images were reconfirmed as pathological on SPECT. Additionally SPECT revealed three lesions not seen on planar images. Fourteen lesions were seen by both imaging techniques. All together SPECT improved diagnostic accuracy of 99m Tc - HMPAO - WBC scintigraphy in 7/28 patients. Conclusion: more inflammatory lesions in the abdomen are revealed by SPECT and volume rendering, than by planar imaging equivocal lesions seen on planar images can be characterised as positive or negative by SPECT. SPECT artefacts can cause possible false positive results; therefore usual planar imaging cannot be omitted if SPECT is performed

    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.

    Full Text Available Rationale. Heart failure (HF is accompanied by the development of an imbalance between oxygen- and nitric oxide-derived free radical production leading to protein nitration. Both chlorinating and peroxidase cycle of Myeloperoxidase (MPO contribute to oxidative and nitrosative stress and are involved in tyrosine nitration of protein. Ceruloplasmin (Cp has antioxidant function through its ferroxidase I (FeOxI activity and has recently been proposed as a physiological defense mechanism against MPO inappropriate actions. Objective. We investigated the relationship between plasma MPO-related chlorinating activity, Cp and FeOxI, and nitrosative stress, inflammatory, neurohormonal, and nutritional biomarkers in HF patients. Methods and Results. In chronic HF patients (n=81, 76 ± 9 years, NYHA Class II (26; Class III (29; Class IV (26 and age-matched controls (n=17, 75 ± 11 years, CTR, plasma MPO chlorinating activity, Cp, FeOxI, nitrated protein, free Malondialdehyde, BNP, norepinephrine, hsCRP, albumin, and prealbumin were measured. Plasma MPO chlorinating activity, Cp, BNP, norepinephrine, and hsCRP were increased in HF versus CTR. FeOxI, albumin, and prealbumin were decreased in HF. MPO-related chlorinating activity was positively related to Cp (r= 0.363, P<0.001, nitrated protein, hsCRP, and BNP and inversely to albumin. Conclusions. Plasma MPO chlorinated activity is increased in elderly chronic HF patients and positively associated with Cp, inflammatory, neurohormonal, and nitrosative parameters suggesting a role in HF progression.

    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

    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.

To assess the effect of β-adrenoblockers (BAB on myocardial remodeling, immuno-inflammatory reactions and endothelial dysfunction in patients with ischemic heart disease and chronic heart failure (CHF.Material and methods. 84 patients with ischemic CHF of II-IV functional class were involved in the study. They were randomized in two groups. The first group was presented with 43 patients receiving carvedilol in addition to standard therapy for 24 weeks; the second group was presented with 41patients receiving metoprolol. Echocardiography, 6-minute walk test were applied. Blood levels of primary and secondary lipid peroxidation (LP products, cytokines, endothelin-1 (ET-1, intercellular adhesive molecule (VCAM-1 were determined.Results. Both of BAB improved the clinical condition and physical working ability of patients with CHF. Carvedilol in comparison with metoprolol was more effective in myocardial remodeling prevention, inhibition of pro-inflammatory cytokines [tumor necrosis factor alpha (TNF-α, interleukins (IL-1β IL-6] and LP. Besides carvedilol increased in endothelium-dependent vasodilatation and reduced in ET-1 and VCAM-1 levels.Conclusion. Long-term carvedilol treatment has anti-inflammatory, antioxidant and endothelium-protective effects as well as improves haemodynamics. 

  5. The judgement of the inflammatory activity of the chronic infectious arthritis with the aid of the radio-isotopes

    International Nuclear Information System (INIS)

    The evaluation of the activity of inflammatory joint diseases is difficult. The more recently used isotopic methods are either - in the case of joint scanning - not satisfactory to evaluate short term changes of inflammatory activity, or - in the case of joint uptake measurements - not representative for the whole body inflammatory activity activity as only few joints are evaluated. Therefore a whole body profile scanner was used to examine the inflammatory activity of all joints of the extremities except shoulder and hip joints. By the use of a double tracer method - 113mIn-transferrin and 99mTc-pertechnetate - the intra- and extravascular uptake of the investigated regions were evaluated separately. The comparison of patients suffering from rheumatoid arthritis with a control group showed that local blood flow as well as the extravascular activity of pertechnetate were increased in patients with inflammatory joint disease. Furthermore repeated profile scans during the first 2 hours of the examination showed accelerated extravascular pertechnetate turnover in joints of patients with rheumatoid arthritis. The usefullness of this method for the assessment of a short term antirheumatic therapy was studied in 17 patients with rheumatoid arthritis who were examined before, 1 and 2 weeks after the onset of a short term antirheumatic treatment and compared with conventional parameters. Most of the clinical parameters and also some isotopic parameters (total pertechnetate uptake, extravascular pertechnetate uptake, and after 1 week of treatment the In-uptake) improved significantly. Furthermore, a significant correlation was found between most of the clinical parameters and total pertechnetate uptake and extravascular pertechnetate uptake respectively. The presented study shows another method to evaluate the global inflammatory activity of joints in rheumatic diseases also useful to quantify effects of short term antirheumatic treatment. (Author)

    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.

    Thrombosis and inflammation are two major factors underlying chronic thromboembolic pulmonary hypertension (CTEPH). Tissue factor (TF), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α) and monocyte chemoattractant protein 1 (MCP-1) may play critical roles in the process of CTEPH thrombosis and pulmonary vascular remodeling. Ten patients with a confirmed diagnosis of CTEPH, 20 patients with acute pulmonary thromboembolism and 15 patients with other types of pulmonary hypertension were enrolled in this study, along with 20 healthy subjects as the control group. The immunoturbidimetric method was used to determine the plasma content of CRP. The plasma levels of TNF-α, MCP-1, and TF antigen were measured by an enzyme-linked immunosorbent assay, and TF activity was measured by the chromogenic substrate method. Percoll density gradient centrifugation was used to separate peripheral blood mononuclear cells from plasma. The level of monocyte TF mRNA was examined by reverse transcriptase-polymerase chain reaction. The correlations between all indices described above were analyzed. In CTEPH patients, the expression of CRP, TNF-α, and MCP-1 was significantly higher than that in controls (P CRP, MCP-1, and TNF-α significantly correlated with the level of TF antigen in plasma. TF gene expression was increased in patients with CTEPH, suggesting that blood-borne TF mainly comes from mononuclear cells. TF expression significantly correlated with levels of CRP, TNF-α and MCP-1. These factors may play an important role in the development of CTEPH via the inflammation-coagulation-thrombosis cycle.

    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.

    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).

    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

    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.

    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.

    2007-02-01

    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.

    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.

    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.

The purpose of this study was to investigate whether a combination of mixed tocopherols and alpha lipoic acid (ALA) would alter biomarkers of oxidative stress and inflammation in subjects with Stage 3–4 CKD.

  11. 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.

    Scientific evidence illustrated the health hazards of exposure to nitrites for prolonged time. Nitrites affected several body organs due to oxidative, inflammatory and apoptosis properties. Furthermore, thymoquinone (TQ) had curative effects against many diseases. We tried to discover the impact of both sodium nitrite and TQ on inflammatory cytokines contents in testicular tissues and hormonal balance both in vivo and in vitro. Fifty adult male SD rats received 80mg/kg sodium nitrite and treated with either 25 or 50mg/kg TQ daily by oral-gavage for twelve weeks. Testis were removed for sperms' count. Testicular tissue homogenates were used for assessment of protein and gene expression of IL-1β, IL-6, TNF-α, Nrf2 and caspase-3. Serum samples were used for measurement of testosterone, LH, FSH and prolactin. Moreover, all the parameters were measured in human normal testis cell-lines, CRL-7002. Sodium nitrite produced significant decrease in serum testosterone associated with raised FSH, LH and prolactin. Moreover, sodium nitrite significantly elevated TNF-α, IL-1β, IL-6, caspase-3 and reduced Nrf2. TQ significantly reversed all these effects both in vivo and in vitro. In conclusion, TQ ameliorated testicular tissue inflammation and restored the normal balance of sex hormones induced by sodium nitrite both in vivo and in vitro. PMID:27038016

    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.

    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 BACKGROUND: Intra-coronary stents have been extensively employed in percutaneous coronary revascularization. However, despite breakthroughs and developments associated to this new technology, novel complications and findings have emerged compelling the cardiac surgeon to cope with this new scenario. The presence of an intra-coronary foreign body (stent might induce an inflammatory reaction carrying functional and structural repercussions of the coronary artery and surrounding cardiac muscle. METHOD:Patients, who had previously undergone stent implantation (6 to 18 months and were submitted to coronary artery bypass surgery, had biopsies taken from the grafted coronary artery distal to the stent and from the adjacent muscle. The collected samples were processed and stained with hematoxylin-eosin and histologically studied. RESULTS:The histology of the coronary artery distal to the stent revealed chronic inflammatory processes and an intimal acute inflammatory infiltrate, with polymorphonuclear leukocytes even at long term follow-up, 12 months after stent implantation, disclosing an ongoing inflammatory process. The myocardium adjacent to the stent implantation site exhibited a significant chronic inflammatory infiltrate and fibrosis compatible with myocarditis. CONCLUSION:The presence of an intra-coronary stent induces an acute and chronic inflammatory reaction, even over the long term, with involvement of the distal coronary artery and surrounding myocardium. Further studies are necessary to assess the inflammatory process extension and its consequences.

    2011-01-01

    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 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 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

  5. Safety Assessment of Commonly Used Nanoparticles in Biomedical Applications: Impact on Inflammatory Processes

    Nanotechnology offers great promise in the biomedical field. Current knowledge of nanoparticles' (NPs) safety and possible mechanisms of various particle types' toxicity is insufficient. The role of particle properties and the route of particles administration in toxic reactions remain unexplored. In this thesis, we aimed to inspect the interrelationship between particle size, chemical composition and toxicological effects of four candidate NPs for drug delivery systems: gold (Au), chitosan, silica, and poly (lactide-co-glycolide) (PLGA). Mice model was combined with in vitro study to explore NPs' safety. We investigated mice survival, weight, behavior, and pro-inflammatory changes. NF-kappaB induction was assessed in vitro using the Luciferase Assay System. As observed in mice, Au NPs had a higher toxicity profile at a shorter duration than the other NPs. This was significantly in concordance with pro-inflammatory changes which may be the key routes of Au NPs toxicity. Although silica NPs induced NF-kappaB, they were less toxic to the mice than Au NPs and did not lead to the pro-inflammatory changes. Chitosan NPs were toxic to the mice but failed to cause significant NF-kappaB induction and pro-inflammatory changes. These findings indicate that chitosan NPs might not have the same pathophysiologic mechanism as the Au NPs. Comparative analysis in this model demonstrated that PLGA NPs is the safest drug delivery candidate to be administered subcutaneously.

    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.

Patients and methods: Patients were treated in a randomized, double-blind, parallel group, placebo-controlled trial with SFC 250 twice daily (n=26 or placebo (n=26 for 12 weeks. At the start and end of treatment, inflammation biomarkers (sputum and serum, lung function, and health status (COPD Assessment Test [CAT] questionnaire were measured. Results: Although a numerical decrease in differential neutrophil count was observed from baseline, SFC 250 did not significantly reduce sputum neutrophils compared with placebo, nor were there significant changes from baseline in the other biomarkers (sputum or serum, lung function, or CAT, versus placebo. Squamous epithelial cell contamination in some sputum samples rendered them unacceptable for analysis, which reduced the sample size to n=19 (SFC 250 and n=10 (placebo. However, inclusion of contaminated samples did not affect the overall trend of the outcome. Ad hoc bootstrap statistical analysis showed a 27.9% (SFC 250 and 1.3% (placebo decrease in sputum neutrophils. Sputum IL-8 decreased by 43.2% after SFC 250 but increased by 48.3% with placebo. Responder analyses showed 42% of patients had ≥20% decrease in neutrophils from baseline; and 47% of patients had a ≥200 pg/mL change in sputum IL-8 following SFC 250 versus 20% after placebo; both changes are considered clinically

  10. Impairment induced by chronic occupational cadmium exposure during brazing process

    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

    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.

    OBJECTIVE. Enteric bacteria play a significant role in the pathogenesis of non-steroidal anti-inflammatory drug (NSAID)-induced small intestinal damage. However, the association between small intestinal bacterial overgrowth (SIBO) and NSAID-induced small intestinal damage remains unclear. The aim of the study was to examine the association between SIBO and the presence of NSAID-induced severe small intestinal damage or its symptoms in chronic NSAID users. MATERIALS AND METHODS. Forty-three patients who had been using NSAIDs for over 3 months were enrolled. They were examined by capsule endoscopy and a lactulose hydrogen breath test (LHBT). We defined severe small intestinal damage as the presence of more than four small erosions or large erosions/ulcers. The LHBT result was considered positive if there was an increase in the level of breath hydrogen gas of >20 ppm above baseline. RESULTS. Out of 43 patients, 22 (51%) had severe small intestinal damage. The LHBT was positive in 5 of 21 patients (24%) without severe small intestinal damage and in 13 of 21 patients (59%) with severe small intestinal damage. Multiple logistic regression analysis showed that an LHBT-positive result was significantly associated with increased odds ratio for severe small intestinal damage (OR, 6.54; 95% CI, 1.40-30.50). There was no significant difference in the presence of symptoms between the LHBT-positive and LHBT-negative patients with severe small intestinal damage. CONCLUSION. SIBO might have a role in the development of severe small intestinal damage in chronic NSAID users. PMID:24417613

    Full Text Available Abstract Introduction Myrtol standardized is established in the treatment of acute and chronic bronchitis and sinusitis. It increases mucociliar clearance and has muco-secretolytic effects. Additional anti-inflammatory and antioxidative properties have been confirmed for Myrtol standardized, eucalyptus oil, and orange oil in several in vitro studies. Objective The aim of this study was to prove the ability of essential oils to reduce cytokines release and reactive oxygen species (ROS production derived from ex vivo cultured alveolar macrophages. Material and methods Alveolar macrophages from patients with chronic obstructive pulmonary disease (COPD, n = 26, GOLD III-IV were pre-cultured with essential oils (10-3-10-8% for 1 h and then stimulated with LPS (1 μg/ml. After 4 h and 20 h respectively a cellular reactive oxygen species (ROS using 2',7'-dichlorofluorescein (DCF, and b TNF-α, IL-8, and GM-CSF secretion were quantified. Results In comparison with negative controls, pre-cultured Myrtol, eucalyptus oil and orange oil (10-4% reduced in the LPS-activated alveolar macrophages ROS release significantly after 1+20 h as follows: Myrtol - 17.7% (P = 0.05, eucalyptus oil -21.8% (P α reduction: Myrtol (-37.3%, P α reduction at 1+4 h and 1+20 h did not vary (Myrtol: -31.9% and -37.3% respectively, P = 0.372 indicating that this effect occurs early and cannot be further stimulated. Myrtol reduced the release of GMCSF by -35.7% and that of IL-8 only inconsiderably. Conclusions All essential oils tested have effective antioxidative properties in ex vivo cultured and LPS-stimulated alveolar macrophages. Additionally, Myrtol inhibited TNF-α and GM-CSF release best indicating additional potent anti-inflammator y activity.

    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.

    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)

    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.

  19. Identification of inflammatory processes in temporomandibular joint (TMJ) by 99mTc-HMPAO in animal model

    International Nuclear Information System (INIS)

    Temporomandibular joint (TMJ) is a synovial joint that represents the junction of mandible with skull. TMJ and mastication muscles are affected by temporomandibular disorders (TMDs). During the last two decades the advances in imaging diagnostic of TMJ have greatly contributed to the assessment of the TMJ disorders. Labelled leukocytes with technetium- 99m hexamethyl propylene amine oxime (99mTc-HMPAO) represent an efficient method that generates images based in physiological and/or biochemical changes related to inflammation. The aim of this study was to investigate the potential usefulness of technetium-99m labelled leukocytes scintigraphy in the diagnosis of TMJ inflammatory process applying a rabbit TMJ arthritis model. Arthritis was induced unilaterally with an intra-articular injection of ovalbumin in left ATM. On the contra-lateral side, the same dose of saline was injected. After five days, leukocytes were labeled with HMPAO and 99mTc-HMPAO TMJ scintigraphic images were made. After twelve days a computed tomography was realized. Scintigraphic images obtained five days after induction of TMJ inflammation showed the localization of inflammatory process. The results were expressed as cpm of activity found in left ATM and contra-lateral side. Significant differences of activity were found between inflamed articulation and contra-lateral side (P = 0,0073). In conclusion, the method of leukocytes labeled with 99mTc showed to be sensitive in detection of inflammatory disorders of TMJ and can be of great value in early diagnostic of these disorders.

    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.

    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.

    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...

    Obesity is an energy-rich condition associated with overnutrition, which impairs systemic metabolic homeostasis and elicits stress. It also activates an inflammatory process in metabolically active sites, such as white adipose tissue, liver, and immune cells. As consequence, increased circulating levels of proinflammatory cytokines, hormone-like molecules, and other inflammatory markers are induced. This determines a chronic active inflammatory condition, associated with the development of th...

    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.

    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.

    Full Text Available Background and purpose of the study:Considering the role of inflammation in acute cerebrovascular accidents, anti-inflammatory treatment has been considered as an option in cerebrovascular diseases. Regarding the properties of Setarud (IMOD™ in immune regulation, the aim of the present study was to evaluate the role of this medication in treating patients with acute ischemic stroke.Methods:In this randomized clinical trial, 99 patients with their first ever acute ischemic stroke were divided into two groups of IMOD™ (n = 49 and control (n = 50. The control group underwent routine treatment and the intervention group underwent routine treatment plus daily intermittent infusion of IMOD™ (250mg on the first day and then 375mg into DW5% serum during a 30-minute period for 7 days. The serum levels of inflammatory markers were evaluated on the first day (baseline and on 4th and 7th days. Data were analyzed and the results were compared.Results and major conclusion:58 males (58.6% and 41 females (41.4% with a mean age of 67.00 ± 8.82 years, who had their first ever stroke attack, were enrolled in this trial. Treatment with IMOD™ showed a decreasing trend in IL-6 levels compared to the control group (p = 0.04. In addition, the treatment resulted in the control of increasing serum levels of hsCRP after 7 days compared to the control group (p = 0.02. There was an insignificant decrease in TNF-α and IL-1 levels in the IMOD™ group. Considering the prominent role of inflammation after an ischemic cerebral damage, it appears that treatment with IMOD™ improves the inflammatory profile. Therefore, IMOD™ (Setarud might be considered as a therapeutic option in the acute ischemic stroke. However, future studies are necessary on its long-term results and clinical efficacy

  15. Alteration of the digestive motility linked with radiation-induced inflammatory processes in rats

    International Nuclear Information System (INIS)

    Exposure to ionizing radiation, whether accidental or for medical reasons, may lead to gastro-intestinal injury, characterized by nausea, vomiting, diarrhea and abdominal cramps. The aetiology of radiation-induced diarrhea remains to date unclear. In this study, we have investigated the acute effects of a 10 Gy abdominal irradiation on rat digestive functions. The objective of the first study was to evaluate the role of sensory afferent neurons, capsaicin-sensitive, on morphological changes and the inflammatory response following exposure. Three days after irradiation, we observed an inflammatory response characterized by neutrophils infiltration and mast cells de-granulation. No effect of capsaicin pre-treatment was seen on these parameters. However, neutrophils infiltration was increased as early as one day after irradiation in capsaicin-treated rats. No difference in severity of diarrhea was observed after denervation nor in morphological changes. These data demonstrate that abdominal irradiation results in diarrhea concomitant with an inflammatory response, and that sensory innervation does not play a major protective role. The objective of the rest of the work was in the first instance to characterize radiation-induced alterations of intestinal and colonic motility leading to diarrhea and secondly to evaluate the role of serotonin in such disorders. Perturbations in intestinal (MMC) and colonic (LSB) motor profiles were observed from the first day onwards. Migrating motor complexes (MMC) were completely disrupted at three days at the same time as the onset of diarrhea. In addition to inhibition of LSB, colonic fluid absorptive capacity was decreased and serotonin colonic tissue levels were increased three days after irradiation. Radiation-induced diarrhea was reduced by treatment with an antagonist of 5-HT3 receptors, granisetron, as were alterations of colonic motility and serotonin tissue levels. However, this treatment did not significantly ameliorate fluid

    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

    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.

    Full Text Available 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.

    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 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.

    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.

    2007-09-01

    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.

  7. 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)

    The cysteine protease cathepsin C (CatC) activates granule-associated proinflammatory serine proteases in hematopoietic precursor cells. Its early inhibition in the bone marrow is regarded as a new therapeutic strategy for treating proteolysis-driven chronic inflammatory diseases, but its complete inhibition is elusive in vivo Controlling the activity of CatC may be achieved by directly inhibiting its activity with a specific inhibitor or/and by preventing its maturation. We have investigated immunochemically and kinetically the occurrence of CatC and its proform in human hematopoietic precursor cells and in differentiated mature immune cells in lung secretions. The maturation of proCatC obeys a multistep mechanism that can be entirely managed by CatS in neutrophilic precursor cells. CatS inhibition by a cell-permeable inhibitor abrogated the release of the heavy and light chains from proCatC and blocked ∼80% of CatC activity. Under these conditions the activity of neutrophil serine proteases, however, was not abolished in precursor cell cultures. In patients with neutrophilic lung inflammation, mature CatC is found in large amounts in sputa. It is secreted by activated neutrophils as confirmed through lipopolysaccharide administration in a nonhuman primate model. CatS inhibitors currently in clinical trials are expected to decrease the activity of neutrophilic CatC without affecting those of elastase-like serine proteases. PMID:26884336

    Magnetic resonance elastography (MRE) is an imaging method that reveals the mechanical properties of tissue, modelled as a combination of " viscosity" and " elasticity" . We recently showed reduced brain viscoelasticity in multiple sclerosis (MS) patients compared with healthy controls, and in the relapsing-remitting disease model experimental autoimmune encephalomyelitis (EAE). However, the mechanisms by which these intrinsic tissue properties become altered remain unclear. This study investigates whether distinct regions in the mouse brain differ in their native viscoelastic properties, and how these properties are affected during chronic EAE in C57Bl/6 mice and in mice lacking the cytokine interferon-gamma. IFN-γ(-/-) mice exhibit a more severe EAE phenotype, with amplified inflammation in the cerebellum and brain stem. Brain scans were performed in the sagittal plane using a 7 T animal MRI scanner, and the anterior (cerebral) and posterior (cerebellar) regions analyzed separately. MRE investigations were accompanied by contrast-enhanced MRI scans, and by histopathology and gene expression analysis ex vivo. Compared with the cerebrum, the cerebellum in healthy mice has a lower viscoelasticity, i.e. it is intrinsically " softer" . This was seen both in the wild-type mice and the IFNγ(-/-) mice. During chronic EAE, C57Bl/6 mice did not show altered brain viscoelasticity. However, as expected, the IFNγ(-/-) mice showed a more severe EAE phenotype, and these mice did show altered brain elasticity during the course of disease. The magnitude of the elasticity reduction correlated with F4/80 gene expression, a marker for macrophages/microglia in inflamed central nervous system tissue. Together these results demonstrate that MRE is sensitive enough to discriminate between viscoelastic properties in distinct anatomical structures in the mouse brain, and to confirm a further relationship between cellular inflammation and mechanical alterations of the brain.

    2009-01-01

    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.

  13. Dynamics of genetic processes in chronically irradiated populations of small mammals

    International Nuclear Information System (INIS)

    The distinctive features of dynamics of mutagenesis in mammalian populations under chronic low-intensive irradiation were first revealed. The main of them is gradual increase in mutability in somatic cells and embryonal lethality during series of irradiated generations of animals (bank vole - Clethrionomys glareolus). The data obtained strongly suggest that there are oppositely directed processes in natural populations after irradiation of more than 20 generations of animals: on the one hand, accumulation of mutations (genetic load of populations) and pre-mutation events which increase genome instability of germ and somatic cells in consecutive generations of animals, and on the other, formation of genetic radio adaptation through better functioning protection systems. In this period of micro evolution in chronically irradiated populations, the frequencies of genetic damages could be higher if the radiation adaptation doesn't form. (authors)

    New perspectives have emerged regarding the processes associated with depressive disorders and their many comorbid conditions. Particular attention has been paid to the potential role of inflammatory factors in promoting these illnesses. These inflammatory responses include those elicited by pathogenic stimuli, as well as sterile inflammatory processes, such as those related to severe or chronic stress. These diverse challenges may activate common processes in which cytokines, which are inflammatory signaling molecules, provoke the dysregulation of several growth factors, including brain-derived neurotrophic factor, fibroblast growth factor-2, macrophage migration inhibitory factor, and erythropoietin. The result of such dysregulation favors the development of depressive disorders and their comorbid illnesses, such as heart disease, diabetes, autoimmune conditions, and poststroke depression.

    1997-01-01

    Full Text Available Emigration of leukocytes from the circulation into tissue by transendothelial migration, is mediated subsequently by adhesion molecules such as selectins, chemokines and integrins. This multistep paradigm, with multiple molecular choices at each step, provides a diversity in signals. The influx of neutrophils, monocytes and lymphocytes into inflamed tissue is important in the pathogenesis of chronic inflammatory bowel disease. The importance of each of these groups of adhesion molecules in chronic inflammatory bowel disease, either in human disease or in animal models, will be discussed below. Furthermore, the possibilities of blocking these different steps in the process of leukocyte extravasation in an attempt to prevent further tissue damage, will be taken into account.

    The aim of this study was to evaluate the activity of the ethanolic extract of geopropolis (EEGP) from Melipona scutellaris and its fractions on the modulation of neutrophil migration in the inflammatory process, and the participation of nitric oxide (NO) pathway, as well as to check the chemical profile of the bioactive fraction. EEGP and its aqueous fraction decreased neutrophil migration in the peritoneal cavity and also the interaction of leukocytes (rolling and adhesion) with endothelial cells. The levels of chemokines CXCL1/KC and CXCL2/MIP-2 were not altered after treatment with EEGP and the aqueous fraction. It was found that the injection of NO pathway antagonists abolished the EEGP and the aqueous fraction inhibitory activity on the neutrophil migration. The expression of intercellular adhesion molecule type 1 (ICAM-1) was reduced, and nitrite levels increased after treatment with EEGP and aqueous fraction. In the carrageenan-induced paw edema model, EEGP and the aqueous fraction showed antiedema activity. No pattern of flavonoid and phenolic acid commonly found in propolis samples of Apis mellifera could be detected in the aqueous fraction samples. These data indicate that the aqueous fraction found has promising bioactive substances with anti-inflammatory activity. PMID:23737853

    The study is based on the investigation of 32 patients suspected in inflammatory process of abdomen cavity, lungs and bones. In 11 of them 99mTc- HMPAO (370 mBq) was used for labelling and in 21 - 111In-oxine (10-14 mBq). The leucocyte labelling effectiveness is higher when 111In oxine was used. Cell restitution in both methods was equal. In patients with positive findings inlammatory focus is visualized best 18-24 hrs after injection of 111In-leucocytes, and 1-2 hrs when 99mTc-leucocytes were used. The use of 99mTc-HMPAO for leucocyte labelling has the following advantages over 111In-oxine: superior quality of the image of inflammatory focus, lower radiation load (10 times), simpler labelling procedure (in plasma medium), accessibility of the radionuclide. The disadvantages are assosiated with its excretion through the kidneys and intestines. 1 tab., 1 fig., 4 refs

    Chronic low back pain (CLBP) is a common, yet challenging condition for both patients and clinicians. Several studies have demonstrated a strong association between CLBP and psychological factors such as anxiety, fear-avoidance, self-efficacy, catastrophizing and depression. These factors are closely linked with emotional states; however, it is unknown whether CLBP patients process their emotions differently from asymptomatic individuals. The aim of this case-control study was to investigate the relationship between CLBP and emotional processing. A sample of 110 participants comprising of 55 patients with chronic back pain and 55 individuals without a history of CLBP were assessed using the Emotional Processing Scale (EPS-25). The EPS-25 generates an overall score, and also scores pertaining to five individual emotional processing factors--avoidance, suppression, unregulated emotion, impoverished emotional experience and signs of unprocessed emotion. Chronic back pain patients scored significantly higher in the overall EPS-25 score (p chronic back pain. PMID:23756033

    Inflammatory bowel diseases are chronic diseases divided into two major forms, ulcerative colitis and Crohn's disease, which are both associated with a chronic inflammatory condition of the gastrointestinal tract. Recent studies have shown that the resolution of inflammatory conditions is a biosynthetically active process where new pro-resolution lipid mediators derived from omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), such as E- and D-series resolvins, protectins, and macrophage mediator in resolving inflammation (maresins), have potent anti-inflammatory activity and serve as specialised mediators that play an important role in the resolution of inflammation. Recent studies have also shown the role of resolvins in referred hyperalgesia associated with different inflammatory processes, such as the visceral pain caused by inflammatory bowel disease. There are many reports describing the principal effects of EPA- and DHA-derived mediators in experimental models of inflammatory bowel diseases. This review focuses on the recent studies on the important role played by pro-resolution lipid mediators in controlling the inflammatory process associated with inflammatory bowel diseases.

There are no definitive findings about the effects of cryotherapy on the process of muscle regeneration. The aim of the present study was to evaluate the effects of a clinical-like cryotherapy on inflammation, rege...

    Internal root resorption is a chronic inflammatory process initiated within the pulp space with the loss of dentin. This condition demands a comprehensive understanding of the pathologic process, so as to identify the cause and arrest the resorptive phenomena. It is a rare occurrence, asymptomatic, with slow progression, detected through routine radiographic examination, where it appears as a radiolucent lesion. This paper reports a clinical case of inflammatory internal root resorption in th...

    © 2015 by the Shock Society. 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 mic...

    The authors studied the influence of the main antiphlogistic agents (prednisolone, acetylsalicylic acid, rheopyrine, chloroquine and indomethacine) on the thermal effect of the peripheral blood erythrocytes in man. It was found that only chloroquine possessed a significant inhibitory effect. This fact pointed to the inhibition by chloroquine of energy production in the process of glycolysis, which could be regarded as one of the factors of the therapeutic action of this preparation.

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

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

    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, t...

  15. Intracellular Secretory Leukoprotease Inhibitor Modulates Inositol 1,4,5-Triphosphate Generation and Exerts an Anti-Inflammatory Effect on Neutrophils of Individuals with Cystic Fibrosis and Chronic Obstructive Pulmonary Disease

    Full Text Available Secretory leukoprotease inhibitor (SLPI is an anti-inflammatory protein present in respiratory secretions. Whilst epithelial cell SLPI is extensively studied, neutrophil associated SLPI is poorly characterised. Neutrophil function including chemotaxis and degranulation of proteolytic enzymes involves changes in cytosolic calcium (Ca2+ levels which is mediated by production of inositol 1,4,5-triphosphate (IP3 in response to G-protein-coupled receptor (GPCR stimuli. The aim of this study was to investigate the intracellular function of SLPI and the mechanism-based modulation of neutrophil function by this antiprotease. Neutrophils were isolated from healthy controls (n=10, individuals with cystic fibrosis (CF (n=5 or chronic obstructive pulmonary disease (COPD (n=5. Recombinant human SLPI significantly inhibited fMet-Leu-Phe (fMLP and interleukin(IL-8 induced neutrophil chemotaxis (P<0.05 and decreased degranulation of matrix metalloprotease-9 (MMP-9, hCAP-18, and myeloperoxidase (MPO (P<0.05. The mechanism of inhibition involved modulation of cytosolic IP3 production and downstream Ca2+ flux. The described attenuation of Ca2+ flux was overcome by inclusion of exogenous IP3 in electropermeabilized cells. Inhibition of IP3 generation and Ca2+ flux by SLPI may represent a novel anti-inflammatory mechanism, thus strengthening the attractiveness of SLPI as a potential therapeutic molecule in inflammatory airway disease associated with excessive neutrophil influx including CF, non-CF bronchiectasis, and COPD.

    Alterations in reward and punishment processing have been reported in adults suffering from long-term cannabis use. However, previous findings regarding the chronic effects of cannabis on reward and punishment processing have been inconsistent. In the present study, we used functional magnetic resonance imaging (fMRI) to reveal the neural correlates of reward and punishment processing in long-term cannabis users (n = 15) and in healthy control subjects (n = 15) with no history of drug abuse. For this purpose, we used the well-established Monetary Incentive Delay (MID) task, a reliable experimental paradigm that allows the differentiation between anticipatory and consummatory aspects of reward and punishment processing. Regarding the gain anticipation period, no significant group differences were observed. In the left caudate and the left inferior frontal gyrus, cannabis users were - in contrast to healthy controls - not able to differentiate between the conditions feedback of reward and control. In addition, cannabis users showed stronger activations in the left caudate and the bilateral inferior frontal gyrus following feedback of no punishment as compared to healthy controls. We interpreted these deficits in dorsal striatal functioning as altered stimulus-reward or action-contingent learning in cannabis users. In addition, the enhanced lateral prefrontal activation in cannabis users that is related to non-punishing feedback may reflect a deficit in emotion regulation or cognitive reappraisal in these subjects.

    Neutrophils play a critical role in acute and chronic inflammatory diseases. N-formyl peptides, which originate from bacterial peptides or mitochondrial proteins bind with a high binding affinity to formyl peptide receptor 1 (FPR1). N-formyl peptide-FPR1 is involved in the pathogenesis of sterile and infectious inflammatory processes and causes phagocytosis of pathogens or injured cells by neutrophils. Excessive activation of neutrophils by binding of N-formyl peptides is associated with tissue injury requiring drugs that block FPR1-dependent signaling. Here, we review the roles of FPR1 as a critical regulator of inflammatory processes and its involvement in pathological conditions. PMID:27100350

  20. Radiology of chronic diseases of the ankle joint

    International Nuclear Information System (INIS)

    The etiology of chronic diseases of the ankle joint comprises a wide spectrum including chronic inflammatory processes and chronic degenerative, tumorous and neuropathic processes, as well as some specific syndromes based on chronic changes of the ankle joint. Of the inflammatory processes, chronic juvenile arthritis (JVC) is the most common disease. However, also Reiter disease, psoriasis or chronic monoarthritid diseases such as gout, as well as granulomatous diseases (tuberculosis, sarcoidosis) and fungal infections, may affect the ankle joint in a chronic course. Chronic degenerative changes are usually secondary due to abnormal positioning of the joint constituents or repetitive trauma. Neuropathic changes, as frequently seen in the course of diabetes, present with massive osseous destruction and malposition of the articular constituents. Chronic osseous as well as cartilaginous and synovial changes are seen in hemoplici patients. Chronic traumatic changes are represented by pigmented villonodular synovitis (PVNS), and chondromatosis, both with a predilection for the ankle joint. Due to the possibilities of magnetic resonance imaging (MRI), diagnosis of chronic ankle changes includes chronic ligamentous, tendinous and soft tissue changes. With the use MRI, specific syndromes can be defined which particularly affect the ankle joint in a chronic way, such as the os trigonum syndrome, the anterolateral impingement syndrome and the sinus tarsi syndrome. Nevertheless, plain film radiographs are still the basic element of any investigation. MRI, however, can be potentially used as a second investigation, saving an unnecessary cascade of investigations with ultrasound and CT. The latter investigations are used only with very specific indications, for instance CT for subtle bone structures and sonography for a limited investigation of tendons or evaluation of fluid. Particularly due to the possibilities of MRI and the development of special gradient-echo imaging or
