Systemic infection with Alaria americana (Trematoda). (1/1842)

Alaria americana is a trematode, the adult of which is found in mammalian carnivores. The first case of disseminated human infection by the mesocercarial stage of this worm occurred in a 24-year-old man. The infection possibly was acquired by the eating of inadequately cooked frogs, which are intermediate hosts of the worm. The diagnosis was made during life by lung biopsy and confirmed at autopsy. The mesocercariae were present in the stomach wall, lymph nodes, liver, myocardium, pancreas and surrounding adipose tissue, spleen, kidney, lungs, brain and spinal cord. There was no host reaction to the parasites. Granulomas were present in the stomach wall, lymph nodes and liver, but the worms were not identified in them. Hypersensitivity vasculitis and a bleeding diathesis due to disseminated intravascular coagulation and a circulating anticoagulant caused his death 8 days after the onset of his illness.  (+info)

Enhanced Th1 and dampened Th2 responses synergize to inhibit acute granulomatous and fibrotic responses in murine schistosomiasis mansoni. (2/1842)

In murine schistosomiasis mansoni, CD4(+) Th1 and Th2 cells participate in the ovum-induced granulomatous inflammation. Previous studies showed that the interleukin-12 (IL-12)-induced Th1 response strongly suppressed the Th2-cell-mediated pulmonary granuloma development in naive or primed mice. However, liver granulomas were only moderately suppressed in egg-vaccinated, recombinant IL-12 (rIL-12)-treated infected mice. The present study shows that repeated rIL-12 injections given during early granuloma development at 5 to 7 weeks after infection prolonged the Th1 phase and resulted in gamma interferon-mediated suppression of liver granulomas. The timing is crucial: if given at 6 to 8 weeks, during the Th2-dominated phase of florid granuloma growth, the treatment is ineffective. Daily injections of rIL-12 given between 5 and 7.5 weeks during the period of granuloma growth achieved a somewhat-stronger diminution in granuloma growth with less deposition of collagen but caused 60% mortality and liver pathology. In contrast, combined treatment with rIL-12 and anti-IL-4-anti-IL-10 monoclonal antibody (MAb) injections given during the Th2 phase strongly inhibited liver granuloma growth without mortality. The diminished inflammatory response was accompanied by less deposition of collagen in the liver. Moreover, neutralization of endogenous IL-12 by anti-IL-12 MAbs effectively decreased the early Th1 phase (between 5 and 6 weeks after infection) but not the developing Th2 phase (5 to 7 weeks) of granuloma development. These studies indicate that the granulomatous response in infected mice can be manipulated by utilizing the Th1-Th2-subset antagonism with potential salutary results in the amelioration of fibrous pathology.  (+info)

N,N'-Diacetyl-L-cystine-the disulfide dimer of N-acetylcysteine-is a potent modulator of contact sensitivity/delayed type hypersensitivity reactions in rodents. (3/1842)

Oral N-acetyl-L-cysteine (NAC) is used clinically for treatment of chronic obstructive pulmonary disease. NAC is easily oxidized to its disulfide. We show here that N,N'-diacetyl-L-cystine (DiNAC) is a potent modulator of contact sensitivity (CS)/delayed type hypersensitivity (DTH) reactions in rodents. Oral treatment of BALB/c mice with 0.003 to 30 micromol/kg DiNAC leads to enhancement of a CS reaction to oxazolone; DiNAC is 100 to 1000 times more potent than NAC in this respect, indicating that it does not act as a prodrug of NAC. Structure-activity studies suggest that a stereochemically-defined disulfide element is needed for activity. The DiNAC-induced enhancement of the CS reaction is counteracted by simultaneous NAC-treatment; in contrast, the CS reaction is even more enhanced in animals treated with DiNAC together with the glutathione-depleting agent buthionine sulfoximine. These data suggest that DiNAC acts via redox processes. Immunohistochemically, ear specimens from oxazolone-sensitized and -challenged BALB/c mice treated with DiNAC display increased numbers of CD8(+) cells. DiNAC treatment augments the CS reaction also when fluorescein isothiocyanate is used as a sensitizer in BALB/c mice; this is a purported TH2 type of response. However, when dinitrofluorobenzene is used as a sensitizer, inducing a purported TH1 type of response, DiNAC treatment reduces the reaction. Treatment with DiNAC also reduces a DTH footpad-swelling reaction to methylated BSA. Collectively, these data indicate that DiNAC in vivo acts as a potent and effective immunomodulator that can either enhance or reduce the CS or DTH response depending on the experimental conditions.  (+info)

The requirement of an adherent cell substratum for the growth of developing plasmacytoma cells in vivo. (4/1842)

The intraperitoneal injection of pristane (2,6,10,14-tetramethylpentadecane) produces an environment conductive to primary plasmacytoma growth in as few as 3 days. After pristane injection, the total free peritoneal cell population increases from a normal value of 1.55 X 10(6) to 5.28 X 10(6) and remains at this elevated level for at least 50 days. The adherent peritoneal cell population, composed of both mononuclear cells and polymorphonuclear leukocytes, is the primary source of this increase. In the pristane-conditioned peritoneum, these cells rapidly form a chronic granuloma on the peritoneal connective tissues. Daily subcutaneous treatment of mice with 0.5 mg of hydrocortisone beginning simultaneously with pristane injection prevents the increase in the peritoneal cell population, granuloma formation, d the production of a conditoned environment. In mice treated with hydrocortisone beginning 3 days after pristane injection, however, neither the peritoneal cell increase nor the production of a conditioned environment is prevented. The intraperitoneal injection of thioglycolate medium at 4-day intervals produces an elevation of the free adherent peritoneal cell population similar to pristane, but does not produce a granuloma or a conditioned environment. The intraperitoneal transfer of thioglycolate-induced adherent peritonel cells to mice treated with pristane and hydrocortisone simultaneously restores the production of a conditioned environment. These findings indicate that the adherent peritoneal cell population is responsible for the conditioning effect, and that the establishment of a resident population of these cells is necessary to produce conditioning.  (+info)

Experimental murine schistosomiasis in the absence of B7 costimulatory molecules: reversal of elicited T cell cytokine profile and partial inhibition of egg granuloma formation. (5/1842)

The granulomatous inflammation in infection with the helminth Schistosoma mansoni represents a cellular hypersensitivity reaction mediated by, and dependent upon, MHC class II-restricted CD4+ Th cells sensitized to parasite egg Ags. The current work examines the role and significance of the B7:CD28/CTLA-4 pathway in providing the costimulation necessary for the activation of these pathogenic T cells. In vitro T cell responses in B7-1-/- mice, 7-8 wk postinfection, were no different from wild-type controls, but the absence of B7-2 molecules resulted in a decrease in egg Ag-induced proliferation with increased IFN-gamma production. Both B7-1-/- and B7-2-/- mice exhibited intact granuloma formation. In contrast, CD4+ Th cells from B7-1/2 double-deficient mice displayed a dramatic loss of proliferative capacity upon stimulation with egg Ag. Most strikingly, these T cells secreted only IFN-gamma, but not IL-4 and IL-10, a pattern entirely opposite to that displayed by wild-type controls. Despite these major differences in T cell reactivity, B7-1/2-/- mice had only a limited reduction of granuloma size and fibrosis, without appreciable difference in cellular composition. These results show that substantial granuloma formation can occur under conditions of limited T cell expansion and restricted Th1-type cytokine production. They also support the notion that the combined effect of B7 signaling is not as critical for Th1 cell activation as it is for the development of the Th2 dominant environment characteristic of the evolving schistosome infection in H-2b mice.  (+info)

Role of macrophage scavenger receptors in hepatic granuloma formation in mice. (6/1842)

In mice homozygous for the gene mutation for type I and type II macrophage scavenger receptors (MSR-A), MSR-A-/-, the formation of hepatic granulomas caused by a single intravenous injection of heat-killed Corynebacterium parvum was delayed significantly for 10 days after injection, compared with granuloma formation in wild-type (MSR-A+/+) mice. In the early stage of granuloma formation, numbers of macrophages and their precursor cells were significantly reduced in MSR-A-/- mice compared with MSR-A+/+ mice. In contrast to MSR-A+/+ mice, no expression of monocyte chemoattractant protein-1, tumor necrosis factor-alpha, and interferon-gamma mRNA was observed in MSR-A-/- mice by 3 days after injection. Also in MSR-A-/- mice, uptake of C. parvum by Kupffer cells and monocyte-derived macrophages in the early stage of granuloma formation was lower and elimination of C. parvum from the liver was slower than in MSR-A+/+ mice. In the livers of MSR-A+/+ mice, macrophages and sinusoidal endothelial cells possessed MSR-A, but this was not seen in the livers of MSR-A-/- mice. In both MSR-A-/- and MSR-A+/+ mice, expression of other scavenger receptors was demonstrated. These data suggest that MSR-A deficiency impairs the uptake and elimination of C. parvum by macrophages and delays hepatic granuloma formation, particularly in the early stage.  (+info)

The p47(phox-/-) mouse model of chronic granulomatous disease has normal granuloma formation and cytokine responses to Mycobacterium avium and Schistosoma mansoni eggs. (7/1842)

Chronic granulomatous disease (CGD) is a genetic disorder of NADPH oxidase in which phagocytes are defective in generating reactive oxidants. CGD patients suffer from recurrent infections and exuberant and persistent tissue granuloma formation. We hypothesized that abnormal granulomata in CGD may result from aberrant T-cell-mediated cytokine responses. To assess Th-1-type cytokine responses and granulomata, we challenged p47(phox-/-) and wild-type mice with avirulent (SmD) or virulent (SmT) variants of Mycobacterium avium 2-151. To assess Th-2-type cytokine responses and granulomata, we used Schistosoma mansoni eggs (SME). Mononuclear cells were harvested, and cytokine responses were determined by enzyme-linked immunosorbent assay or reverse transcriptase PCR. Following SmD or SmT challenge, splenocytes from p47(phox-/-) and wild-type mice generated similar polar Th-1 responses (increased levels of gamma interferon and basal levels of interleukin 4 [IL-4] and IL-5). By 8 weeks after SmT challenge, exuberant splenic granulomata developed in p47(phox-/-) and wild-type mice. After SME challenge, thoracic lymph node mononuclear cells from p47(phox-/-) and wild-type mice generated similar mixed Th-1 and Th-2 cytokine responses to SME antigen and concanavalin A. Peak lung granuloma sizes and rates of regression were similar in p47(phox-/-) and wild-type mice. These results suggest that exuberant granulomatous inflammation in CGD is probably not the result of skewing of T-cell responses toward the Th-1 or Th-2 pole. Appropriate regression of established tissue granulomata in p47(phox-/-) mice challenged with SME suggests that abnormal granuloma formation in CGD is stimulus dependent and is not an invariant feature of the disease.  (+info)

Sarcoidosis of the upper respiratory tract and its association with lupus pernio. (8/1842)

In a series of 34 patients with sarcoidosis affecting the upper respiratory tract and nose, 26 had lupus pernio (LP) and 17 had sarcoidosis of the upper respiratory tract (SURT). In nine patients these features coexisted. A patient presenting with SURT carried a 50% risk of developing LP although one feature could be present without the other. Both were disorders of women of the child-bearing years of life. SURT, like LP, was an indicator of chronic fibrotic sarcoidosis, developing insidiously and progressing indolently over the years. It was complicated by ulceration, septal perforation, and LP. Three patients had nasal septal perforations, in two instances following submucous resection. This operation is contraindicated in patients with active sarcoidosis, particularly when granulomas are found on nasal biopsy. The Kveim-Siltzbach skin test was positive in all patients with SURT, making it invaluable in the differential diagnosis of granuloma of the nasal cavity.  (+info)

Recent studies have demonstrated a crucial role for TNF during inflammatory granuloma formation. In addition, TNF has been shown to up-regulate adhesion molecules that participate in cellular recruitment and lymphocyte activation. In the present study, we have examined the mechanism of TNF activation during Schistosoma mansoni egg granuloma formation and its relationship to the expression of ICAM-1. Our initial studies showed that high affinity human soluble TNFR coupled to the Fc portion of an Ig (sTNFR:Fc construct) could effectively diminish granuloma formation and lymphocyte activation in vivo. We have also assessed the increased expression of ICAM-1, its contribution to granuloma development, and its relationship with TNF during lesion formation. Increased steady state ICAM-1 mRNA expression was observed in primary egg granulomas when compared with normal lung and foreign body (Sephadex bead) granulomas, which suggests a role for ICAM-1 in Ag-induced lesion formation. Subsequent studies ...
In pathology, a granuloma is an organized collection of macrophages.[1][5]. In medical practice, doctors occasionally use the term granuloma in its more literal meaning: a small nodule. Since a small nodule can represent anything from a harmless nevus to a malignant tumor, this usage of the term is not very specific. Examples of this use of the term granuloma are the lesions known as vocal cord granuloma (known as contact granuloma), pyogenic granuloma and intubation granuloma, all of which are examples of granulation tissue, not granulomas. Pulmonary hyalinizing granuloma is a lesion characterized by keloid-like fibrosis in the lung, and is not granulomatous. Similarly, radiologists often use the term granuloma when they see a calcified nodule on X-ray or CT scan of the chest. They make this assumption since granulomas usually contain calcium, although the cells that form a granuloma are too tiny to be seen by a radiologist. The most accurate use of the term granuloma requires a ...

Granulomas are nodules caused by inflammation. The inflammation may be the result of infectious or noninfectious causes. Granulomas in the lung typically do not produce any symptoms, but may be detected when a chest x-ray is done for another reason.. Infectious causes of lung granulomas. Infections are the most common cause of lung granulomas, and these infections often involve mycobacteria or fungi.[1] Mycobacteria include tuberculosis as well as organisms that are referred to jointly as nontuberculous mycobacteria (NMT). NMT are found in water and soil.. Fungi that can lead to lung granulomas include Histoplasma, Coccidioides, and Cryptococcus. These fungi are found in soil (and sometimes in bird or bat droppings), and lung infection occurs when the spores are inhaled. [2] [3] [4]. Several other lung infections can also lead to lung granulomas, but are less common.. Non-infectious causes of lung granulomas. Sarcoidosis is the most common noninfectious cause of lung granulomas in the United ...
Large populations of macrophages are a prominent feature of tuberculous granulomas, yet there are many unanswered questions surrounding the spatial organization of macrophage subsets in granulomas and whether macrophages have microenvironment-specific homeostatic or bactericidal functions. Much of what we know about granuloma macrophages comes from animal models that may not represent the spectrum of pathology seen in humans or has been derived from cells removed from the context of the granuloma. To address these questions, we used immunohistochemistry to clarify the interplay of microenvironment and macrophage biology by identifying macrophage subsets and arginase and NOS expression in granulomas from cynomolgus macaques, a nonhuman primate that recapitulates human TB (4). We found that granulomas have macrophage subsets that are stratified into pro- and anti-inflammatory regions with the implication that this organization may limit immunopathogenic antimicrobial activity to bacteria-rich ...

DESCRIPTION (provided by applicant): The long term objective of this proposal is to gain insight into mechanisms of host defense against infectious agents in humans, through the study of leprosy as a model. At the site of infection, organized collections of macrophages form granulomas to defend against the pathogen, Mycobacterium leprae. Our goal is to understand mechanisms of granuloma formation and function in human infectious disease. We will test the hypothesis that distinct subsets of macrophages regulate granuloma formation, and hence host defense. This will be accomplished by using bioengineered 3D microconstructs to encapsulate and confine M?, facilitating immune cell interaction, replicating the in vivo tissue microenvironment where granulomas form. Our aims are: 1) Fabricate artificial granulomas using droplet microfluidics to model human leprosy infection, and, 2) Investigate the role of macrophage subsets in granuloma formation and function. In addition we will study the function of ...
Br J Dermatol. Cutaneous granulomas associated with primary immunodeficiency disorders. We report cutaneous granulomas in a child with ataxia telangiectasia AT and compare the clinical course with similar lesions in an adult with common variable immunodeficiency CVI. A 4-year-old female with AT developed cutaneous granulomas as erythematous plaques. The largest lesion appeared on her left cheek and continued to progress despite treatment with topical and intralesional steroids.. Disease control was obtained initially with oral antibiotics and low-dose oral steroids. On cessation of oral steroids, significant relapse of the facial granuloma occurred. Pulsed and then oral steroids were required to stop the disease process leaving significant scarring. The second case is of cutaneous granulomas in a year-old man, with CVI, who presented with an erythematous reticulate rash on the legs.. We consider it useful to report this patient here as disease control was obtained in a similar way with systemic ...
During acute schistosomiasis worm ova released from adult S. japonicum elicit potent pro-inflammatory responses along with characteristic granuloma formation, which then causes substantial injuries to organs such as the liver and intestine where the eggs are trapped (Hirata et al., 2001). As a result, anti-inflammatory responses to limit excessive liver injury or intestinal hemorrhage are necessary to prevent host lethality (Herbert et al., 2008). In general, acute schistosomiasis is considered a Th1 disease (de Jesus et al., 2002), and a defect in developing a Th2 response during acute schistosomiasis is associated with high lethality in mice (Rani et al., 2012). Given that alternatively activated M2 macrophages possess a high capacity for secretion of Th2 cytokines, their role in limiting pro-inflammatory responses and granuloma formation during acute schistosomiasis has been highly appreciated.. Previous studies have suggested that the trafficking of monocytes and macrophages from peripheral ...

Charcoal, also called black carbon, is used for preoperative localization of tumor (mainly for breast tumors) or needle track localization after biopsy (mainly sarcomas biopsy, due to a potential risk of tumor seeding along needle track with this type of tumor).. Foreign-body granulomas can lead to false-positive findings of FDG PET/CT due to strong FGD uptake. On unenhanced CT, granulomas can show variable configurations, as delimited oval or round shape, or amorphous and linear configuration. Charcoal-induced granulomas usually show a spontaneous high attenuation, due to the high density of carbon particles, and no remarkable enhancement after contrast injection. On US studies, charcoal granulomas are characterized as irregular-shaped lesions, most often with hyperechogenicity and posterior shadowing. On the contrary, tumor recurrences often appear hypoechoic.. As described by Jin Woo Choi, charcoal is known to be a safe and biologically inert material when injected subcutaneously and may ...
Mycobacterium tuberculosis is the pathogenic bacterium that causes tuberculosis (TB), one of the most lethal infectious diseases in the world. The only vaccine against TB is minimally protective, and multi-drug resistant TB necessitates new therapeutics to treat infection. Developing new therapies requires a better understanding of the complex host immune response to infection, including dissecting the processes leading to formation of granulomas, the dense cellular lesions associated with TB. In this work we pair experimental and computational modeling studies to explore cytokine regulation in the context of TB. We use our next-generation hybrid multi-scale model of granuloma formation (GranSim) to capture molecular, cellular, and tissue scale dynamics of granuloma formation. We identify TGF-β1 as a major inhibitor of cytotoxic T-cell effector function in granulomas. Deletion of TGF-β1 from the system results in improved bacterial clearance and lesion sterilization. We also identify a novel
Objectives Vocal fold granulomas are benign lesions of the larynx commonly caused by gastroesophageal reflux, intubation, and phonotrauma. Current medical therapy includes inhaled corticosteroids to target inflammation that leads to granuloma formation. Particle sizes of commonly prescribed inhalers range over 1 to 4 µm. The study objective was to use computational fluid dynamics to investigate deposition patterns over a range of particle sizes of inhaled corticosteroids targeting the larynx and vocal fold granulomas. Study Design Retrospective, case-specific computational study. Setting Tertiary academic center. Subjects/Methods A 3-dimensional anatomically realistic computational model of a normal adult airway from mouth to trachea was constructed from 3 computed tomography scans. Virtual granulomas of varying sizes and positions along the vocal fold were incorporated into the base model. Assuming steady-state, inspiratory, turbulent airflow at 30 L/min, computational fluid dynamics was used ...
IN REPLY: Thanks to Dr. Wooltorton for a nice and optimistic overview of noninvasive treatments for umbilical granulomas. I would add a resource1 to his armamentarium that praises the curative effect of common salt on umbilical granuloma. This article1 states that the high concentration of sodium ion in the area draws water out of the cells and results in shrinkage and necrosis of the wet granulomatous tissue.. However, contrary to Dr. Wooltortons impression, we did not ignore the easily reversed root causes of these lesions; we mentioned them in the first two sentences of the abstract and the first part of the discussion of the article.2 Dr. Wooltorton also implies that our technique is only pertinent for small umbilical granulomas such as in the case we presented in our article.2 In reality, it is effective for large pedunculated granulomas and avoids a prolonged and usually unsuccessful trial of conservative treatment. In our experience of treating hundreds of umbilical granulomas in ...
Contact granulomas are benign lesions usually located on the posterior third of the vocal fold, which corresponds to the vocal process of the arytenoid cartilage. Contact granulomas may occur unilaterally or bilaterally.
Image 4. Table of Contents Answer: This is a non-necrotizing granuloma that is composed of epithelioid cells, multinucleated giant cells, and lymphocytes. The asterisk marks a Langhans giant cell with peripherally-oriented nuclei. The epithelioid cells are activated macrophages that have a secretory function rather than a phagocytic one. Metabolic products include calcium salts that can crystallize to form birefringent crystals, which must not be mistaken for foreign bodies.. Return. Answer: The respiratory problems that developed while the patient was keeping pets, the patchy ground-glass opacities and micronodules on HRCT, the evidence of air trapping on expiratory CT, the bronchiolar and patchy, alveolar lymphoid infiltrates and non-necrotizing granulomas are consistent with the diagnosis of hypersensitivity pneumonia.

HISTOPATHOLOGIC DESCRIPTION: SLIDE A: Lung: Up to 75% percent of the parenchyma is replaced by multifocal to coalescing granulomas composed of necrotic centers with occasional mineralization surrounded by numerous epithelioid macrophages, multinucleated giant cells (Langhans and foreign body type), and more peripherally by lymphocytes and plasma cells. Some granulomas are circumscribed by a thin fibrous connective tissue capsule. Multifocally, remaining alveolar septa are lined by hyperplastic type II pneumocytes. Alveolar spaces contain eosinophilic proteinaceous material (edema) admixed with numerous foamy alveolar macrophages, fewer lymphocytes, and scattered hemorrhage and fibrin. Multifocally, aggregates of lymphocytes and plasma cells surround blood vessels, which occasionally contain fibrin thrombi. Diffusely, the pleura is thickened to up ...
Summary: Tuberculosis (TB) is a complex disease, and the success of the bacterium as an intracellular pathogen is the outcome of its close and longstanding coevolution with the mammalian host. The dialogue between Mycobacterium tuberculosis and the host is becoming understandable at the molecular, cellular, and tissue level. This has led to the elucidation of the (i) interaction between pattern recognition receptors and pathogen-associated molecular patterns, (ii) cross-talk between immune cells, and (iii) mechanisms underlying granuloma development. Disease as an eventual but not a necessary consequence of infection results from a sensitive balance between protective immunity and destructive pathology. Early events, governed largely by conserved mechanisms of host recognition, impact not only on type and course of adaptive immunity but also on lung parenchymal function. New interpretations of how these responses shape the lung environment and direct granuloma development emphasize that the ...
Central giant-cell granuloma (CGCG) is a benign condition of the jaws. It is twice as likely to affect women and is more likely to occur in 20- to 40-year-old people. Central giant-cell granulomas are more common in the mandible and often cross the midline. CGCG lesions are found more commonly in the anterior of the maxilla and the mandible in younger people (before age 20). They are characterized by large lesions that expand the cortical plate and can resorb roots and move teeth. They are composed of multi-nucleated giant cells. CGCG has a slight predilection for females. Radiographically : It appears as multilocular radiolucencies of bone.The margin of the lesion has scalloped appearance and is well demarcated. Resorption and divergence of roots is also seen. There are two types of CGCGs, non-aggressive and aggressive. The former has a slow rate of growth and thus less likely to resorb roots and perforate the cortical plate. The aggressive form has rapid growth and thus is much more likely to ...
Data Availability StatementAll relevant data are within the paper. or NTB. Finally, the circulating levels of all of the angiogenic elements examined were considerably reduced following effective chemotherapy. Conclusion As a result, our data demonstrate that PTB can be connected with elevated degrees of circulating angiogenic elements, probably reflecting vascular and endothelial dysfunction. Furthermore, a few of these circulating angiogenic elements could confirm useful as biomarkers to monitor disease intensity, bacterial burden and therapeutic responses. Intro Granulomatous inflammation can be characteristic of several autoimmune and infectious illnesses [1,2]. The tuberculous granuloma, a central feature in mycobacterial disease, may be the hallmark framework of tuberculosis (TB) disease and disease [1,2]. These granulomas are often seen as a the concomitant advancement of hypoxia, which functions as stimulus for vascularization [3]. Vascularization in animal types of TB offers been proven ...

Over the past several years, our lab has been attempting to determine the mechanism by which inbred strains of mice, which we use as model mammalian hosts, respond to experimental filarial infections. The outcome of these studies indicates that an important host defense mechanism is the formation of multicellular aggregates of leukocytes called granulomas around incoming infectious larvae. Our previous studies indicated an important role for T cells (for the recruitment of a robust population of leukocytes and for activating macrophages along the alternative pathway of activation), B lymphocytes (particularly the B1 subset), and macrophages and eosinophils (for participating in the granulomas). We have demonstrated the crucial importance of antifilarial antibodies of the IgM isotype in binding to the surface of the larvae and facilitating the adhesion of activated macrophages to the larvae. We have further shown that the in vitro cytoadherence assay is a good surrogate for in vivo granuloma ...
Both divinyl benzene copolymer (plastic) beads and schistosome eggs produce inflammatory reactions after intravenous deposition into the lung of a mouse. As reported previously, the schistosome egg granuloma is an immunologic reaction of the delayed hypersensitivity type; this inflammatory process is prevented by immunosuppressive measures, and characteristically demonstrates an anamnestic response. In contradistinction, the plastic bead granuloma appears to be characteristic of a foreign body reaction; it is unaffected by immunosuppressive measures and does not demonstrate an anamnestic response with repeated exposure. The data in this report suggest that the granuloma formation around plastic beads is a nonimmunologic reaction induced by chemical mediators of inflammation. This proposal is supported by the following findings: the plastic beads activate Hageman factor in normal human and mouse plasma; the plastic beads induce vascular permeability-enhancing activity as measured in guinea pig ...

GASTROINTESTINAL DISEASES OF BIRDS. James K Morrisey, DVM, DABVP (Avian). Diseases of the Oral Cavity. The oropharynx is a common site for a variety of lesions in birds. A thorough examination of the oral cavity is usually not possible in the awake parrot, however, a quick visual examination can be performed and the pet sedated if lesions are noted. Other species such as raptors, passerines, and columbiformes are more easily examined while awake. Clinical signs associated with oropharyngeal diseases vary, but may include halitosis, anorexia, inappetance, dysphagia, rubbing of the beak, or gaping.. Plaques or granulomas are a clinical sign common with several diseases including bacterial infections, yeast infections, hypovitaminosis A, parasitic diseases, and viral diseases. Cytology and culture of the lesion will help to determine the cause. Cytological samples may be collected by rubbing a sterile cotton-tipped applicator along the lesion and then rubbing the sample on a clean slide. Several ...

Consistent with this notion, IL-27R-deficient mouse granulomas comprise larger numbers of lymphocytes than wild-kind granulomas . Ordway et al. depleted mice of CD4+ T cells at different phases of an infection by Mtb and confirmed that this triggered disorganisation of the granulomatous lesion at all phases . Deletion experiments within the in vitro mannequin of human granuloma have instructed that CD4+ cells constitute the one T-cell inhabitants completely crucial for granuloma formation (Allain et al., unpublished).. The associated variant is embedded in an H3K27A histone mark, but can be in a genomic area that features IL12B, a gene identified to underlie Mendelian susceptibility to mycobacterial disease . These observations support the virgin soil speculation, which postulates that the earlier lack of publicity to a pathogen results in hyper-susceptibility to infection, morbidity and mortality. tuberculosis complex was in fact already widespread around 4000 years ago in Ethiopia and TB ...

As with anything small and foreign, its reaction to vaccine ingredients is potent, poorly understood, unpredictable, and as the Italian researchers say, may be undesirable. The immune system may dispatch an army of large white blood cells called macrophages to engulf the foreign bodies and contain them in swellings and granulomas at the injection site. But if the contaminants are swept away in the bloods circulation to any distant site or organ including the microbiota, which regulate numerous functions including the immune system, their effect could be felt long after they covertly entered the body. ...

A foreign body granuloma is a mass lesion consisting of a foreign body with host reaction. Its diagnosis is not always easy in respect of its similarity to soft tissue sarcoma. The most common foreign body is surgical sponge which can be detectable macroscopically. We present a foreign body granuloma in the left buttock caused by microscopic surgical materials that developed into a large lesion. An 80-year-old man with a history of surgery for dislocation of the left hip 20 years earlier, presented with a slowly growing mass that had expanded rapidly over the preceding 2 months. Histological examination revealed organizing granulation tissue surrounding the scattered foreign materials. One should be aware of foreign body granuloma at previously operated sites even without a retained macroscopic gauze sponge.
Granulomatous interstitial nephritis (GIN) is a rare entity identified in ,1% of native kidney biopsies. The most frequent aetiology is drug-related, followed by systemic granulomatous conditions. Among drugs implicated in GIN, antibiotics and non-steroidal anti-inflammatory drugs (NSAIDs) are the most frequent. We report the case of a 45-year-old white man referred to a nephrology consult due to chronic kidney disease. He had a history of arterial hypertension with 10 years of evolution, hyperuricaemia, medicated with allopurinol and NSAID abuse for at least 20 years. Urine sediment was blunt, without proteinuria. Renal ultrasound was normal. A kidney biopsy revealed well-defined epithelioid granulomas with glomerular wrinkling and collapse. Infectious and systemic conditions were excluded, favouring the hypothesis of drug-induced GIN, probably related to NSAIDs. Kidney biopsy remains the gold standard for the diagnosis of GIN. Facing a patient with renal failure without significant proteinuria ...
Usually a small red, oozing and bleeding bump, pyogenic granulomas appear as an overgrowth of tissue caused by irritation, physical trauma or hormonal factors. The most common locations for pyogenic granulomas are the head, neck, upper trunk, hands and feet. Although pyogenic granulomas are benign growths, sometimes cancer can mimic these nodules so your physician will likely order a biopsy to be safe. Children, pregnant women, and those taking certain medications have a higher chance of developing a pyogenic granuloma. ...
Peripheral giant-cell granuloma (PGCG) is an oral pathologic condition that appears in the mouth as an overgrowth of tissue due to irritation or trauma. Because of its overwhelming incidence on the gingiva, the condition is associated with two other diseases, though not because they occur together. Instead, the three are associated with each other because they appear frequently on gingiva: pyogenic granuloma and peripheral ossifying fibroma. Because of its similar microscopic appearance to the bony lesions called central giant-cell granulomas, peripheral giant-cell granulomas are considered by some researchers to be a soft tissue equivalent. The appearance of peripheral giant-cell granulomas is similar to pyogenic granulomas. The color ranges from red to bluish-purple, but is usually more blue in comparison to pyogenic granulomas. It can be sessile or pedunculated with the size usually being less than 2 cm. There is a gender difference with 60% of the disease occurring in females. The prevalence ...
Granuloma - A granuloma is a little breadth of deepening in tissue due to injury, such as from an infection.

The histopathological hallmark of hepatic resistance to visceralizing species of Leishmania is the development of functional granulomas [10, 11, 14]. Here we used IHC as a tool to characterise the different cells involved in the hepatic granuloma development at different stages of experimental VL in BALB/c mice, complemented by quantitative image analysis and detection of Leishmania antigen.. Immunohistochemical methods described here are a powerful tool to characterise host responses to infection in situ in mouse models of Leishmania spp. infection. These have also been used in other granulomatous diseases that share some, though not all properties with VL [15-18]. Additionally these techniques can be utilised to evaluate the cellular mechanism of new vaccines, drugs and treatment regimens [19-21]. Therefore this study provides in depth insights into the cellular dynamics of experimental VL in a context relevant to advancing health.. In agreement with previous studies [22, 23], we observed that ...
Granuloma is a term in medical dictionary for a minute collection of immune cells which are known as macrophages. Granulomas figure while the immune system tries to wall off substances which it recognizes as foreign body but is not capable to remove. Such substances comprise infectious organisms like bacteria and fungi and other materials like sutureas well as keratin fragments. So, a granuloma is a particular kind of inflammation that can take place in a wide various kind of diseases. The adjective granulomatous means distinguishing by granulomas. All granulomas may contain extra cells and matrix. These contain neutrophils, lymphocytes, multinucleated giant cells, eosinophils, fibroblasts and collagen (fibrosis).. ...
Pyogenic Granuloma is also known as lobular capillary haemangioma and Pyogenic granulomata. Pyogenic Granuloma are common benign vascular lesions of the skin and mucosa.
From the question on the page 546. The neurological findings and MRI findings in this case were compatible with both sarcoidosis and human T-lymphotropic virus type 1 (HTLV-1)-associated myelopathy/tropical spastic paraparesis. The diffuse small nodules on the chest CT were consistent with those seen in both sarcoidosis and HTLV-1-associated bronchiolo-alveolar disorder (HABA). Negative PPD skin test, high serum lysozyme and granulomas are all suggestive of sarcoidosis.. Granulomas in sarcoidosis are relatively large and discrete, mainly consist of epithelioid cells and are distributed along the lymphatics.1 The inflammation is typically localised around the granulomas.1 In this case, the granulomas were very loose and small. The predominant cells composing the granulomas were mutinucleated giant cells. The granulomas in this case were different from granulomas observed in sarcoidosis. Moreover, a large number of lymphocytes infiltrated into the bronchioles and small blood vessels breaking the ...
There are two theories for the development of a cholesterol granuloma. In the obstruction-vacuum theory, Eustachian tube dysfunction is thought to cause mucosal edema, which can result in repeated episodes of bleeding and subsequent formation of cysts surrounding the blood. The cysts gradually expand.. In the exposed marrow theory, on the other hand, hyperplastic mucosa is thought to invade underlying bone and expose the bone marrow, which, in turn, bleeds.. Either way, a combination of trapped blood and a surrounding chronic inflammatory response lead to the formation of a cholesterol granuloma. In our patient, the etiology is most likely related to Eustachian tube obstruction caused by previous surgery and radiation for a trigeminal schwannoma.. Histologically, cholesterol granulomas contain yellow-brown fluid consisting of cholesterol crystals, red blood cells, and blood break-down products.. Cholesterol granulomas are surrounded by a fibrous tissue capsule and can be located in any part of ...

The exact cause of sarcoidosis is unknown. What is known is that when a person has the disease, tiny clumps of abnormal tissue (granulomas) form in certain organs of the body. Granulomas are clusters of immune cells.. The disease can affect almost any organ. It most commonly affects the lungs.. Doctors think that having certain genes makes it more likely for a person to develop sarcoidosis. Things that may trigger the disease include infections with bacteria or viruses. Contact with dust or chemicals may also be triggers.. The disease is more common in African Americans and Caucasians of Scandinavian heritage. More women than men have the disease.. The disease often begins between ages 20 and 40. Sarcoidosis is rare in young children.. A person with a close blood relative who has sarcoidosis is nearly five times as likely to develop the condition. ...
Sarcoidosis is a multisystem disease process of unknown etiology whose pathogenesis involves formation of an inflammatory lesion known as a granuloma. Histologically, noncaseating granulomas are prominent in biopsies from lymph nodes or affected organs.

The widely used animal models for tuberculosis ( TB) display fundamental differences from human TB. Therefore, a validated model that recapitulates human lung TB is attractive for TB research. Here, we describe a unique method for establishment of TB infection in an experimental human lung tissue model. The model is based on cell lines derived from human lungs and primary macrophages from peripheral blood, and displays characteristics of human lung tissue, including evenly integrated macrophages throughout the epithelium, production of extracellular matrix, stratified epithelia and mucus secretion. Establishment of experimental infection in the model tissue with Mycobacterium tuberculosis, the bacterium that causes TB, resulted in clustering of macrophages at the site of infection, reminiscent of early TB granuloma formation. We quantitated the extent of granuloma formation induced by different strains of mycobacteria and validated our model against findings in other TB models. We found that ...

Physicians have recently begun using a medical formulation of botulinum toxin, type A to treat vocal fold granulomas caused by overly forceful contact from vocal misuse or overuse. Botulinum toxin, type A, is injected into the muscle of the vocal fold to temporarily limit its mobility and thus decrease injury from forceful contact of vocal folds during voice misuse. This then leads to a decrease in irritation and inflammation allowing the granuloma to heal, as well as prevent new granuloma formation. Since the effects of botulinum toxin, type A injections are short-lasting (three to five months), they sometimes must be performed several times to achieve a desired result.. Injections of medical formulation of botulinum toxin, type A, for granuloma should be performed by a skilled otolaryngologist. (For more information, see Voice Care Team and Spasmodic Dysphonia.). ...
Some clinicians prefer to treat contact granulomas by removing them. However, the tiny injury or wound that results often produces a recurrent granuloma.. A better approach is simply to wait for the granuloma to detach of its own accord. This process of self-detachment, which may take several months, is like an apple maturing and then dropping from the tree: the granuloma continues to grow in size, and once it becomes big enough, the back-and-forth movement of air and the displacement caused by contact with the opposite arytenoid cartilage cause the granuloma to slowly pinch inward at its base and become more and more pedunculated; eventually, the connecting stalk can no longer support the granuloma, and the granuloma breaks free. For an example, see the photos below.. If, however, a persons symptoms are too troublesome to wait for months, then the granuloma can be surgically removed, but while still leaving part of the stalk or base projecting from the surface, so as to avoid re-injuring the ...
The cytologic specimens contain nodular aggregate of hystiocytes, lymphocytes and neutrophils. Epithelioid cells and multinucleated giant cells of the granulomas are usually present, but are not specific of this condition.

Because of the fibrosis, aspirates may be hypocellular.. ...
To the editor: We were interested to read the paper, Radiation Therapy of Midline Granuloma by Fauci, Johnson, and Wolff (Ann Intern Med 84:140-147, 1976). They report, however, a concept and experience at variance with ours. Granulomatous lesions of the nose, as we have seen them, have usually been conveniently classifiable as either necrotizing granuloma with vasculitis consistent with Wegeners granulomatosis, polymorphic reticulosis ( 1 ), specific infectious granuloma, or lymphoma. The non-specific pathologic features referred to in the paper have suggested to us either that the biopsy was inadequate or that the disease process has not yet evolved into ...
These are both vascular lesions, the former probably some form of hamartoma, the latter an abnormal vascular response to trauma. Haemangiomas such as the bright red Campbell de Morgan spots are extremely common and rarely get confused with anything more sinister. However in later life many people develop vascular papules or nodules that can mimic melanoma. If you can confidently remove the blood by pressure (and often the lesion will collapse and shrink temporarily in volume after you do this) you do not need to worry further. If not, you need advice. One variety referred to as a venous lake, is commonly seen on the lips, is easily compressible and is often confused with melanotic macules of the lips (which are not compressible).. Pyogenic granulomas are best viewed as a vascular proliferation in response to wounding, in which the vascular granulation tissue continues to grow inappropriately. They can occur in patients of any age, and at any body site but are most common on the fingers in the ...
Cats with eosinophilic granuloma complex (EGC) may have one or more of four patterns of skin disease.. The most frequent form is eosinophilic plaque. This is a rash comprising raised red to salmon-colored and flat-topped, moist bumps scattered on the skin surface. The most common location is on the ventral abdomen and inner thigh.. Another form of EGC is the lip ulcer. This is a painless, shallow ulcer with raised and thickened edges that forms on the upper lip adjacent to the upper canine tooth. It is often found on both sides of the upper lips.. The third form of the EGC is the collagenolytic granuloma. This is a firm swelling that may be ulcerated. The lesions may form on the skin, especially of the face, in the mouth, or on the feet, or may form linear flat-topped raised hairless lesions on the back of the hind legs, also called linear granuloma.. ...

Granuloma, Sterile - Also Known As: Sterile granuloma, sterile pyogranuloma Transmission or Cause: Unknown, but thought to be an immune-mediated disease. Affected Animals:
Granulomas form by a stepwise series of events, starting when T helper cells recognise protein peptides presented to them by antigen presenting cells bearing histocompatibility class II molecules. Immunological reactivity or inflammation attract monocyte macrophages which fuse to form multinucleated giant cells and onwards to epithelioid cells. Granuloma formation is aided by a cavalcade of chemotactic factors; Th1 cells induce interleukin (IL)-2, interferon gamma, and tumour necrosis factor (TNF) with the help of IL-12 and costimulator B7. The resulting exuberant granuloma formation is associated with active cell mediated hypersensitivity and tissue destruction. This framework is also remodelled by chemokines, adhesion molecules, matrix receptors of the integrin family, costimulators B7 and CD28, IL-12, and RANTES (regulated on activation normal T cells as secreted).. Bronchoalveolar fluid (BALF) reveals this macrophage class II-CD4Th1 cell synergy with its awesome cytokine cascade. Angiotensin ...
How Is This Condition Diagnosed?. A lick granuloma is usually diagnosed by the appearance of the lesion and a history of the dog licking or chewing at the area. To determine the cause of the licking, your veterinarian may perform a number of tests, including skin scrapes (gently scraping the surface of the skin with a dull instrument to identify mites), skin cultures, skin biopsies (tissue samples), and blood work. He or she may also recommend a radiograph (x-ray) to see if there is a foreign body under the skin or if there has been trauma to the bone or joint beneath the lesion.. How Is a Lick Granuloma Treated?. Treatment for lick granuloma can take many months and usually requires some patience. If an underlying condition has been identified, treatment of this condition should help resolve the granuloma. Treatment may include medications such as antibiotics, antifungals, parasite treatment, antihistamines, pain medication, hormone supplements, or topical steroids.. Of course, preventing the ...

Is blockade of TNF-α the complete answer to treatment of rheumatoid arthritis? In terms of toxicity, anti-TNF-α agents fortunately have only produced side effects in line with their mode of action; infections are increased, and latent tuberculosis can be activated (partly by the known action of antitumour necrosis factor monoclonals on granulomas).22 It is, however, possible to screen and minimise the reactivation of tuberculosis with prophylaxis. Other problems include inducing antibodies against the drugs themselves and also switching to autoantibody production as is seen with Th2 cells. A greater problem is the need for ongoing therapy, which entails giving protein long term to patients, although it can now be a fully human monoclonal protein. Over time a finite loss of response occurs. Both a primary and a secondary non-response have been proposed for this complex mechanism.23 This is a particular problem in patients currently approved for therapy by the National Institute of Health and ...
As with anything small and foreign, its reaction to vaccine ingredients is potent, poorly understood, unpredictable, and as the Italian researchers say, may be undesirable. The immune system may dispatch an army of large white blood cells called macrophages to engulf the foreign bodies and contain them in swellings and granulomas at the injection site. But if the contaminants are swept away in the bloods circulation to any distant site or organ including the microbiota, which regulate numerous functions including the immune system, their effect could be felt long after they covertly entered the body ...
