Descrição: The aim of the present study was to assess the effects of an anticholinesterase agent, pyridostigmine bromide (Pyrido), on experimental chronic Chagas heart disease in mice. To this end, male C57BL/6J mice noninfected (control:Con) or chronically infected (5 months) with (chagasic:Chg) were treated or not (NT) with Pyrido for one month. At the end of this period, electrocardiogram (ECG); cardiac autonomic function; heart histopathology; serum cytokines; and the presence of blood and tissue parasites by means of immunohistochemistry and PCR were assessed. In NT-Chg mice, significant changes in the electrocardiographic, autonomic, and cardiac histopathological profiles were observed confirming a chronic inflammatory response. Treatment with Pyrido in Chagasic mice caused a significant reduction of myocardial inflammatory infiltration, fibrosis, and hypertrophy, which was accompanied by a decrease in serum levels of IFN with no change in IL-10 levels, suggesting a shift of immune ...

Chagas Disease: Infection with the protozoan parasite TRYPANOSOMA CRUZI, a form of TRYPANOSOMIASIS endemic in Central and South America. It is named after the Brazilian physician Carlos Chagas, who discovered the parasite. Infection by the parasite (positive serologic result only) is distinguished from the clinical manifestations that develop years later, such as destruction of PARASYMPATHETIC GANGLIA; CHAGAS CARDIOMYOPATHY; and dysfunction of the ESOPHAGUS or COLON.

Current diagnosis of chronic Chagas disease relies on serologic detection of specific immunoglobulin G against Trypanosoma cruzi. However, the presence of parasites detected by polymerase chain reaction (PCR) in patients without positive conventional serologic testing has been observed. We determined the prevalence and clinical characteristics of persons with seronegative results and T. cruzi DNA detected by PCR in a population at high risk for chronic American trypanosomiasis. We studied a total of 194 persons from two different populations: 110 patients were recruited from an urban cardiology clinic, and 84 persons were citizens from a highly disease-endemic area. Eighty (41%) of persons had negative serologic findings; 12 (15%) had a positive PCR. Three patients with negative serologic findings and positive PCR results had clinical signs and symptoms that suggested Chagas cardiomyopathy. This finding challenges the current recommendations for Chagas disease diagnosis, therapy, and blood ...

This laboratory investigates the pathogenesis of chagasic heart disease, caused by the parasite Trypanosoma cruzi. Chagas disease is also an opportunistic infection in HIV/AIDS. We are examining signaling pathways involved in cardiac remodeling as a consequence of the T. cruzi infection. This laboratory is examining the consequences of this infection on cell cycle regulatory proteins (i.e., cyclins) in vitro. Previously, we found that infection induces ERK activation and modulation of the expression and/or activity of cyclins, which function as mediators of cellular proliferation and differentiation. Cyclins are also responsible for remodeling in the cardiovascular system. Therefore, the kinetics of the expression of cyclins in infected cultured cells and co-culture systems are to be studied. In addition, in the mouse model of Chagas disease the kinetics of expression of cell cycle regulatory proteins in the cells of the myocardium of infected mice will be determined and correlated with ...

Trypanosoma cruzi, the protozoan that causes Chagas heart disease, invades endothelial cells in vitro by activating the B-2 kinin receptor (B2R). Here, we demonstrate that mice infected with trypomastigotes develop potent edema after treatment with the angiotensin-converting enzyme (ACE) (or kininase II) inhibitor captopril. Experiments performed with specific kinin receptor (B2R/B1R) antagonists and knockout mice revealed that the early-phase (3-h) edema is mediated by the constitutive B2R, whereas the late-phase (24-h) response depends on stimulation of the up-regulated B1R. Given previous evidence that parasite invasion of cells expressing B2R is potentiated by captopril, we investigated the prerequisites for in vitro infection of Chinese hamster ovary cells overexpressing either B1R or B2R, human umbilical vein endothelial cells activated by lipopolysaccharide, and neonatal rat cardiomyocytes. Our results indicate that captopril potentiates parasite invasion regardless of the kinin ...

Background :Chagas disease is an endemic disease in most Latin American countries. The cardiomyopathy associated with this condition often requires permanent pacing due to bradycardia. The aim of this study was to compare the indications for pacemaker implantation, intraoperative measurements, and long-term follow-up of patients with Chagas cardiomyopathy (ChCM) and ischemic cardiomyopathy (ICM) referred for pacemaker implantation.. Methods : Retrospective study including consecutive patients with ChCM (Group 1) and ICM (Group 2), who underwent pacemaker implantation in a single center.. Results : We analyzed 360 patients. Patients in Group 1 were younger (66.29 ± 7.01 vs 75.3 ± 7.11 years; P = 0.0001) and more often male (72% vs 60%; P = 0.05). Sinus node dysfunction (SND) was more prevalent in Group 1 (70% vs 52%; P = 0.03). Atrioventricular block was less prevalent in Group 1 (30% vs 48%; P = 0.04). No significant differences were found with respect to left ventricular ejection fraction ...

At the SCMR meeting, Nagel was assigned to argue that everybody with COVID-19 should receive a CMR scan to check for myocardial damage.. He went over studies looking into myocardial damage in patients with COVID-19, noting that there are two phases to consider-acute and chronic. Its the latter, Nagel said, that the community will have to increasingly focus on as the pandemic drags on, to explore whether damage identified on CMR leads to problems like chronic cardiomyopathy and LV dysfunction.. Based on accumulated evidence, A COVID infection can harm the heart in the same way as . . . diabetes or long-standing hypertension, or even more, he said. So there is something going on which is not good. It doesnt mean they all have massive myocarditis. Were not talking about fulminant myocarditis.

The protozoan parasite Trypanosoma cruzi (T. cruzi) circulates in the blood upon infection and invades a variety of cells. Parasites intensively multiply during the acute phase of infection and persist lifelong at low levels in tissues and blood during the chronic phase. Natural killer (NK) and NKT cells play an important role in the immune control of T. cruzi infection, mainly by releasing the cytokine IFN-γ that activates the microbicidal action of macrophages and other cells and shapes a protective type 1 immune response. The mechanisms by which immune cells are regulated to produce IFN-γ during T. cruzi infection are still incompletely understood. Here, we show that urokinase plasminogen activator (uPA) is induced early upon T. cruzi infection, and remains elevated until day 20 post inoculation. We previously demonstrated that the inhibitory receptor Ly49E, which is expressed, among others, on NK and NKT cells, is triggered by uPA. Therefore, we compared wild type (WT) to Ly49E knockout (KO) mice

Chronic Chagas disease presents different clinical manifestations ranging from asymptomatic (namely indeterminate) to severe cardiac and/or digestive. Previous results have shown that the immune response plays an important role, although no all mechanisms are understood. Immunoregulatory mechanisms such as apoptosis are important for the control of Chagas disease, possibly affecting the morbidity in chronic clinical forms. Apoptosis has been suggested to be an important mechanism of cellular response during T. cruzi infection. We aimed to further understand the putative role of apoptosis in Chagas disease and its relation to the clinical forms of the disease. Apoptosis of lymphocytes, under antigenic stimuli (soluble T. cruzi antigens - TcAg) where compared to that of non-stimulated cells. Apoptosis was evaluated using the expression of annexin and caspase 3+ by T cells and the percentage of cells positive evaluated by flow cytometry. In addition activation and T cell markers were used for the

Admission:. Longitudinal prospective study, with a cohort of 100 consecutive outpatient subjects (34 to 74 years old; 31 females) with Chagas disease followed-up for at least 10 years at the cardiomyopathy outpatient clinic of University Hospital, Rio de Janeiro, RJ, Brazil, a tertiary care center. Enrollment was from 1995 to 1999. Subjects were born in endemic regions of Minas Gerais, Goias or Bahia States of Brazil and Chagas disease was diagnosed on basis of two positive serum tests, hemagglutination cruzipain-ELISA and indirect immunofluorescence. All subjects were referred to the arrhythmia for risk stratification. At the time of admission none had received nitroderivative therapy. Subjects were classified according to the severity of heart involvement according to Los Andes classification, and divided into three groups: class I - 28 subjects (group 1), class II - 48 subjects (group 2), and class III - 24 subjects (group 3). Clinical and laboratory data were assessed during a personal ...

Amongst adult cats, myocardial disease (cardiomyopathy) is the most common form of heart disease. Hypertrophic cardiomyopathy (HCM) is identified in over 60% of cardiomyopathic cats, with the rest attributable to dilated cardiomyopathy, restrictive cardiomyopathy (endomyocardial or myocardial), arrhythmogenic right ventricular cardiomyopathy, and unclassified cardiomyopathy.. The criteria by which each form of cardiomyopathy is defined are based on echocardiographically-derived parameters; however, there is some overlap between categories, which results in controversy over the classification of some individuals. Of greater importance for these individuals is correct identification of the type of functional abnormality (e.g., systolic dysfunction, diastolic dysfunction, or both), as this has direct implications for patient management.. While pathophysiology of the feline cardiomyopathies differs, affected cats are at risk for the same three adverse sequelae: congestive failure, thromboembolic ...

Purpose: The mechanism of J-wave is not definitely known, although it is generally considered to be a manifestation of ventricular repolarization abnormality. We investigated the current flow consistent with J-wave on electrocardiogram (ECG) using 3-directional magnetocardiography(MCG)with high spacio-temporal resolution.. Methods: Sixty-four-channel 3-D MCG was recorded simultaneously with a digitalized ECG (II, V2, V5) during sinus rhythm in 69 patients (men 54, women 15, mean age 49.2±21.6 ) absence of bundle branch block but with J-wave showing either notched or slurred J-point elevation,0.1mV in at least 2 consecutive leads followed by ST elevation. We compared the direction and distribution of current flow on MCG at the time phase of J-wave with that of the mid to late QRS and ST-T period.. Results Twenty-four patients had organic heart diseases (cardiomyopathy;6, ischemic heart disease;5). 4 of them and 12 of 45 patients without heart disease had episodes of lethal ventricular ...

Treatment is urgently indicated for anyone during the acute phase and for those in whom the infection has been reactivated. In these situations, treatment is almost 100% effective, and the disease can be completely cured.. During the acute phase, Chagas disease can be treated with two antiparasitic medicines: benznidazole* and nifurtimox*. Both medicines are nearly 100% effective in curing the disease if given soon after infection, including the cases of congenital transmission. The efficacy of both diminishes, however, the longer a person has been infected, and the risk of adverse reactions increases with age.. Once Chagas disease reaches the chronic phase, medications wont cure the disease, but they may help slow the progression of the disease and its most serious complications. Adults, especially those with the indeterminate form of the disease, should be offered treatment, but its potential benefits in preventing or delaying the development of Chagas disease should be weighed against the ...

The mechanisms by which Trypanosoma cruzi causes cardiomyopathy and induces neuronal destruction are discussed in this paper. The results suggest that autoimmunity in the chronic phase is the main cause of the progressive cardiac destruction, and that autoreactivity is restricted to the CD4+ T cell compartment. During the acute phase, the neuronal and cardiac fiber destruction occurs when ruptured parasite nests release T. cruzi antigens that bind to the cell surface in the vicinity which become targets for the cellular and humoral immune response against T. cruzi. The various factors involved in the genesis of autoimmunity in chronic T. cruzi infection include molecular mimicry, presentation of self-antigens and imbalance of immune regulation ...

The protozoan parasite Trypanosoma cruzi, causative agent of Chagas disease, depends upon a cell surface-expressed trans-sialidase (ts) to avoid activation of complement-mediated lysis and to enhance intracellular invasion. However these functions alone fail to account for the size of this gene family in T. cruzi, especially considering that most of these genes encode proteins lacking ts enzyme activity. Previous whole genome sequencing of the CL Brener clone of T. cruzi identified ~1400 ts variants, but left many partially assembled sequences unannotated. In the current study we reevaluated the trans-sialidase-like sequences in this reference strain, identifying an additional 1779 full-length and partial ts genes with their important features annotated, and confirming the expression of previously annotated

Symptoms of Chagas disease including 49 medical symptoms and signs of Chagas disease, alternative diagnoses, misdiagnosis, and correct diagnosis for Chagas disease signs or Chagas disease symptoms.

Current treatment is dependent on two drugs, benznidazole or nifurtimox, both of which are highly effective when therapy is initiated at the onset of infection and during the acute phase of the disease. However, very few patients are diagnosed in the acute stages because many people are asymptomatic when first infected, or because the patients do not have access to proper diagnosis and treatment.. The efficacy of both drugs for many patients with chronic Chagas disease diminishes the longer a person has been infected. Available drug treatments have a high level of toxicity and cause side effects severe enough to require interruption of treatment in some patients. Thus, the benefits of medication in preventing or delaying the development of Chagas disease has to be weighed against the long duration of treatment (up to two months) and relatively high rates of adverse reactions that occur in up to 40 percent of treated patients. Additionally, there is currently no available drug intervention for ...

Trypanosoma cruzi is the etiologic agent of Chagas disease. The contributions of parasite and immune system for disease pathogenesis remain unresolved and controversial. The possibility that Chagas disease was an autoimmune progression triggered by T. cruzi infection led some to question the benefit of treating chronically T. cruzi-infected persons with drugs. Furthermore, it provided the rationale for not investing in research aimed at a vaccine which might carry a risk of inducing autoimmunity or exacerbating inflammation. This viewpoint was adopted by cash-strapped health systems in the developing economies where the disease is endemic and has been repeatedly challenged by researchers and clinicians in recent years and there is now a considerable body of evidence and broad consensus that parasite persistence is requisite for pathogenesis and that antiparasitic immunity can be protective against T. cruzi pathogenesis without eliciting autoimmune pathology. Thus, treatment of chronically ...

Chagas disease: Chagas disease, infection with the flagellate protozoan Trypanosoma cruzi.

strain were analyzed, during acute and chronic infection, by means of histological, histochemical, morphometric and electron microscopic techniques. No evidences of destructive changes were apparent. Histochemical demonstration for acetylcholinesterase and catecholamines did not reveal differences in the amount and distribution of intracardiac nerves, in mice with acute and chronic Chagas myocarditis or in non-infected controls. Mild, probably reversible ultrastructural neural changes were occasionally present, especially during acute myocarditis. Intrinsic nerves appeared as the least involved cardiac structure during the course of experimental Chagas disease in mice ...

The etiological treatment of Chagas disease is recommended for all patients with acute or recent chronic infection, but controversies remain regarding the benefit of chemotherapy and interpretations of the parasitological cure after etiological treatment. This study compares the laboratory and clinical evaluations of Chagas disease patients who were diagnosed 13 years earlier. Fifty-eight Chagas disease patients (29 treated with benznidazole and 29 untreated) were matched at the time of treatment based on several variables. Conventional serology revealed the absence of seroconversion in all patients. However, lower serological titres were verified in the treated group, primarily among patients who had the indeterminate form of the disease. Haemoculture performed 13 years after the intervention was positive for 6.9% and 27.6% of the treated and untreated patients, respectively. Polymerase chain reaction tests were positive for 44.8% and 13.8% of the treated and untreated patients, respectively. ...

A specific test is necessary for the diagnosis of Chagas disease. The test detects the presence of the infection through analysis of a blood sample. Anyone who suspects that they may have Chagas disease should ask their doctor to order this test.. Patients who test positive for the infection should have a cardiac check-up. This is done using radiography, an electrocardiogram and occasionally an echocardiogram. Depending on whether or not the patient reports digestive symptoms, the doctor will decide if a digestive tract assessment is needed.. To find out whether you should be tested for Chagas infection, we recommend you take the following test.. ...

The only existing preventive measure against American trypanosomosis, or Chagas disease, is the control of the transmitting insect, which has only been effective in a few South American regions. Currently, there is no vaccine available to prevent this disease. Here, we present the clinical and cardiac levels of protection induced by expression to Trypanosoma cruzi genes encoding the Tc SP and Tc SSP4 proteins in the canine model. Physical examination, diagnostic chagasic serology, and serial electrocardiograms were performed before and after immunization, as well as after experimental infection. We found that immunization with recombinant plasmids prevented hyperthermia in the acute phase of experimental infection and produced lymphadenomegaly as an immunological response against the parasite and additionally prevented heart rate elevation (tachycardia) in the acute and/or chronic stages of infection. Immunization with T. cruzi genes encoding the Tc SP and Tc SSP4 antigens diminished the quality and

Researchers have shown that the Trypanosoma cruzi agent of Chagas disease invades host embryo cells and spreads its mitochondrial DNA (kDNA) minicircles into the hosts genome. Dr. Antonio Teixeira and associates at the University of Brasília, Brazil, inoculated virulent typanosomes in fertile chicken eggs and documented the heritability and fixation of the kDNA mutations in the chicks and their progeny. The results show that kDNA-mutated chickens undergo genotype alterations, developing an inflammatory heart condition similar to Chagas disease in humans.

During remission, the parasite may remain undetectable in the blood for long periods, then return to detectable levels periodically, often triggered by stress or immune system challenge. In humans, reactivation of Chagas disease in patients infected with the human immunodeficiency virus (HIV) has been reported since the early 1990s. The clinical manifestations of reactivated Chagas disease are severe central nervous system (CNS) alterations and cardiomyopathy. Trypomastigotes of T. cruzi, observed by direct microscopic examination of blood smears, characterize the acute phase of infection and confirm Chagas disease reactivation.. Traditional laboratory diagnosis of T. cruzi relies on blood smear observation or serological detection. Unfortunately, these methods lack sensitivity and specificity. PCR ...

Background: This study investigates morphofunctional adaptations of the heart stroma and parenchyma in rats that are chronically infected with Trypanosoma cruzi. Methods: Four-month-old male Wistar rats were randomized into control (n=14) and infected (n=14) groups. Infected animals were inoculated with T. cruzi Y strain. After 9 weeks, the animals were euthanized, and the right atrium (RA) and left ventricle (LV) were removed for biochemical, stereological, and cardiomyocyte mechanical analyses. Results: Infected animals presented cardiomyocyte atrophy and myocardial fibrosis. For these animals, the total volume, length, surface area, and cross-sectional area of cardiomyocytes were significantly reduced, and the total interstitial and collagen volumes were significantly increased in the RA and LV compared to the controls. The total volume and length of blood vessels were significantly increased in the LV, and the total blood vessel surface area was significantly higher in the RA of infected ...

Abstract: Trypanosoma cruzi trans sialidase (TcTS) has been identified as a potential therapeutic target for treatment of Chagas disease.

Researchers have discovered how the parasite Trypanosoma cruzi, which causes Chagas disease, prolongs its survival in infected cells. A protein on the parasite activates the enzyme Akt, which blocks cell death signals, preventing cell destruction and parasite elimination. Chagas disease affects some 8 to 11 million people throughout Latin America and even the United States.

Chagas disease is the single most common cause of congestive heart failure and sudden death in the world. The devastating parasitic infection affects millions of people throughout Central and South America. But as global travel increases, its becoming a greater threat in the United States and Europe as well.
