Rasmussens encephalitis, also known as chronic focal encephalitis (CFE), is a rare inflammatory neurological disease, characterized by frequent and severe seizures, loss of motor skills and speech, hemiparesis (weakness on one side of the body), encephalitis (inflammation of the brain), and dementia. The illness affects a single cerebral hemisphere and generally occurs in children under the age of 15. The condition mostly affects children, with an average age of 6 years. However, one in ten people with the condition develops it in adulthood. There are two main stages, sometimes preceded by a prodromal stage of a few months. In the acute stage, lasting four to eight months, the inflammation is active and the symptoms become progressively worse. These include weakness of one side of the body (hemiparesis), loss of vision for one side of the visual field (hemianopia), and cognitive difficulties (affecting learning, memory or language, for example). Epileptic ...
Cerebral toxoplasmosis is one of the most frequently encountered opportunistic infections in the course of AIDS. The mortality (death) rate is estimated to be greater than 50 percent. Pyrimethamine is a drug that appears promising for the primary prevention of cerebral toxoplasmosis in HIV-infected patients.. AMENDED: 04-04-91 On the first day of therapy, a loading dose is given. After the first day, patients take pyrimethamine or placebo 3 times a week. Patients also take leucovorin calcium orally three times weekly. Enrollment occurs over approximately 12 months. All patients are followed on study until a common study close-out date and final analysis of the study. It is anticipated that this common close-out will occur when the mean duration of time on study therapy will be 3 years (approximately in January, 1994).. ORIGINAL design: On the first day of treatment, patients receive a loading dose of pyrimethamine or placebo, plus of ...
Toxoplasmic encephalitis (encephalitis caused by Toxoplasma gondii) is the most frequent cause of focal central nervous system infection in patients with AIDS. If untreated, the encephalitis is fatal. At present, it is standard practice to give a combination of pyrimethamine and sulfadiazine to treat toxoplasmic encephalitis. The high frequency of sulfonamide-induced toxicity in AIDS patients often makes completion of a full course of therapy difficult. There is some information that high doses of parenteral (such as by injection) clindamycin used with pyrimethamine may be as effective as pyrimethamine plus sulfadiazine in the management of the acute phase of toxoplasmic encephalitis in patients with AIDS. Administration of parenteral clindamycin for prolonged periods of time, however, is costly, requires ...

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a well-defined autoimmune disorder. Hashimotos encephalopathy (HE) is a still controversial entity, lacking definite diagnostic criteria. We described a 14-year-old-girl presenting with a clinical picture consistent with the diagnosis of anti-NMDAR encephalitis, confirmed by NMDAR antibody testing. Four years earlier, she had presented a similar episode of acute encephalopathy diagnosed as HE. Anti-NMDAR encephalitis and HE share similar clinical features so that the differential diagnosis can be difficult if specific antibodies are not tested. The correct diagnosis of anti-NMDAR encephalitis is crucial to plan the appropriate management and follow-up, namely in term of oncological screening, since it can be paraneoplastic in origin. We suggest to re-evaluate the clinical history of all subjects with previous HE diagnosis in order to evaluate the possible diagnosis of anti-NMDAR ...

Anti-epileptic drugs are frequently helpful but usually do not entirely control seizures. Recent studies have shown some success with treatments that suppress or modulate the immune system, in particular those that use corticosteroids, intravenous immunoglobulin, or tacrolimus. Surgery to control seizures may be recommended, particularly in children where recovery potential is high. Some centers suggest early surgery for RE as a way to treat the seizures and to take advantage of developmental neuroplasticy, where different parts of the brain learn new connections following injury or trauma. Surgical procedures, such as functional hemispherectomy (surgery to remove the part of the hemisphere where the seizures start) and functional hemispherotomy (surgically severing all connections between the right and left halves of the brain), may reduce the frequency of seizures and also improve behavior and cognitive abilities. ...

In the years following the initial reports of AIDS in 1981, it was estimated that between 3% and 25% of AIDS patients in the United States would ultimately develop Toxoplasma encephalitis (1). Differences in the incidence of CNS toxoplasmosis reflected differences in the background rate of the parasitic infection among the population. The institution of primary prophylaxis, namely, the administration of antitoxoplasmosis therapy in the face of profound immunosuppression, has resulted in a significant decline in frequency of CNS toxoplasmosis. Following the introduction of highly active antiretroviral therapy (HAART), there has been a further decline in opportunistic infections associated with HIV infection; however, the data regarding the effect of HAART on CNS toxoplasmosis remain controversial. Some investigators have noted as much as a fourfold decline in the clinical recognition of the disease and a similar decline in its presence at autopsy. Others have not found a statistically ...
Brain infections such as meningitis and encephalitis are highly debilitating diseases, and an accurate diagnostic is essential to give patients the best treatment available. For cryptococcal meningitis, clinical trials focus on prevention, for an early diagnosis, and novel ways to use existing treatments or repurpose old drugs.
Today is World Encephalitis Day - the global awareness day for people who have been affected by encephalitis. Founded by The Encephalitis Society in 2014, the day has subsequently helped to raise awareness among millions of people. This year the society is aiming to shine a light on this devastating condition which affects 500,000 people each year by illuminating iconic landmarks, local buildings and homes across the globe. While we are unable to light up our own offices, we are proud to help spread the word about encephalitis.. Encephalitis is an inflammation of the brain. The inflammation is caused either by an infection invading the brain (infectious); or through the immune system attacking the brain in error (post-infectious or autoimmune Encephalitis). Some types of encephalitis are spread by mosquitoes (such as Japanese encephalitis), ticks (such as tick-borne ...
A case of Toxoplasma encephalitis is described in a patient who had received much immunosuppressive therapy for Hodgkins disease. Such cases have been reported in immune suppressed patients outside the United Kingdom, but a search of the literature has not revealed any previous reports from this country. Since Toxoplasma gondii is a frequent pathogen and states of immune suppression are becoming more common, further cases, can be expected. Recognition of the clinical and pathological features is important because the condition can be treated.. ...

The X-linked hyper-immunoglobulin M syndrome (XHIGM) is an uncommon primary combined immunodeficiency disease caused by CD40L gene mutations. A delayed or missed diagnosis of XHIGM is common and concerning, owing to atypical immunoglobulin profile and phenotype of some patients, low recognition, and limited knowledge of clinicians on XHIGM in some underdeveloped areas. Opportunistic infections are a prominent clinical feature of XHIGM. However, toxoplasma encephalitis occurs sporadically and is extremely rare in patients with XHIGM.

We report a case of retinal toxoplasmosis that occurred in a patient with acquired immunodeficiency syndrome who had a previous diagnosis of cerebral toxoplasmosis, despite the patient having had a robust immune response to highly active antiretroviral therapy. Clinical decisions about whether to discontinue secondary prophylaxis for opportunistic infections continue to be challenging. ...
The patient was taken by neurosurgery service to the operating room where a biopsy was taken, which was positive for Toxoplasmosis gondii. The patient was then found to be positive for the human immunodeficiency virus (HIV) with subsequent testing. While in the intensive care unit the patient required mannitol, steroids, and hypertonic saline for cerebral edema, and his neurologic status improved with treatment. The patient was treated for cerebral toxoplasmosis, subsequent Pneumocystis carini pneumonia, oral thrush, and was started on highly active anti-retroviral therapy (HAART).. Toxoplasmosis gondii is an opportunistic intracellular pathogen that has long been recognized as the most frequent cause of brain lesions in acquired immune deficiency syndrome (AIDS) patients.1,2 Seroprevalence of Toxoplasmosis gondii is estimated at 22.5% within the United States (U.S.) and may be higher within the general populous in Europe and tropical countries.3,4 Infection with Toxoplasmosis gondii in ...
Three patients, one male and 2 women, aged 55 years old, respectively 41 and 42 year-old, all 3 diagnosed concomitantly with HIV infection (as very late presenters) and cerebral toxoplasmosis, with a CD4 count of 6, 6 and 7/cmm respectively, viral loads (VL) of 254,000, 57,000 and 156,000 copies/mL respectively, and CSF viral load below the plasmatic VL in all 3 cases. We recorded minimal abnormalities of CSF analysis regarding the number of cells and biochemical exams; all had positive PCR for Toxoplasma gondii in the CSF and positive serology (IgG). All 3 had intracerebral lesions (abscesses) and all were biopsied at the neurosurgery department for diagnostic purpose before knowing their HIV-positive status. They received high doses of oral trimethoprim/sulfamethoxazole (T/S) for toxoplasmosis and antiretroviral therapy in the first 2 weeks after the diagnosis. They repeated cerebral imagery (MRI) after 3 weeks of T/S and had no regression of the size of lesions (although with the decreasing ...
This study analyzed the synthesis of Interferon gamma (IFN-γ), Tumor Necrosis Factor alpha (TNF-α), and Interleukin 10 (IL-10) in chronically infected patients which developed the symptomatic disease as cerebral or ocular toxoplasmosis. Blood from 61 individuals were divided into four groups: Cerebral toxoplasmosis/AIDS patients (CT/AIDS group) (n = 15), ocular toxoplasmosis patients (OT group) (n = 23), chronic toxoplasmosis individuals (CHR group) (n = 13) and healthy individuals (HI group) (n = 10). OT, CHR, and HI groups were human immunodeficiency virus (HIV) seronegative. The diagnosis was made by laboratorial (PCR and ELISA) and clinical subjects. For cytokine determination, peripheral blood mononuclear cells (PBMC) of each patient were isolated and stimulated in vitro with T. gondii antigen. IFN-γ, TNF-α, and IL-10 activities were determined by ELISA. Patients from CT/AIDS and OT groups had low levels of IFN-γ when were compared with those from CHR group. These data suggest the low ...
World Encephalitis Day is held on February 22 each year and is designed to raise awareness of encephalitis, an inflammation of the brain. The global awareness day was created by The Encephalitis Society, a UK registered charity, and announced in October 2013. The inaugural World Encephalitis Day operated under the tagline, "Make Today your First," and highlighted the fact that many people would hear about encephalitis for the first time in a hospital waiting room. Supporters were encouraged to share information on encephalitis to raise awareness globally. One of those supporters was Simon Hattenstone, a survivor of encephalitis and journalist with The Guardian, who wrote: "Encephalitis is such a cruel disease because it is often misdiagnosed - even today. And that delay in diagnosis can have fatal consequences." The Society teamed up with the Institute of Infection and ...
Symptomatic forms of toxoplasmosis are a serious public health problem and occur in around 10-20% of the infected people. Aiming to improve the molecular diagnosis of symptomatic toxoplasmosis in Brazilian patients, this study evaluated the performance of real time PCR testing two primer sets (B1 and REP-529) in detecting Toxoplasma gondii DNA. The methodology was assayed in 807 clinical samples with known clinical diagnosis, ELISA, and conventional PCR results in a 9-year period. All samples were from patients with clinical suspicion of several features of toxoplasmosis. According to the minimum detection limit curve (in CT), REP-529 had greater sensitivity to detect T. gondii DNA than B1. Both primer sets were retrospectively evaluated using 515 DNA from different clinical samples. The 122 patients without toxoplasmosis provided high specificity (REP-529, 99.2% and B1, 100%). From the 393 samples with positive ELISA, 146 had clinical diagnosis of toxoplasmosis and positive conventional PCR. ...
Worldwide, approximately 2 billion people are chronically infected with Toxoplasma gondii with largely yet unknown consequences. Patients with autism spectrum disorders (ASD) similarly as mice with chronic toxoplasmosis have persistent neuroinflammation, hypercytokinemia with hypermetabolism associated with enhanced lipid peroxidation, and extreme changes in the weight resulting in obesity or wasting. Data presented in this review suggest that environmental triggering factors such as pregnancy, viral/bacterial infections, vaccinations, medications, and other substances caused reactivation of latent cerebral toxoplasmosis because of changes in intensity of latent central nervous system T. gondii infection/inflammation and finally resulted in development of ASD. Examples of such environmental factors together with their respective biomarker abnormalities are: pregnancy (increased NO, IL-1 beta, TNF-alpha, IL-6, IL-10, prolactin: decreased IFN-gamma, IL-12), neuroborreliosis (increased IL-1 beta, ...

Toxoplasmosis is a relatively uncommon infectious complication after transplant. Seropositive heart transplant recipients or heart transplant recipients who receive toxoplasmosis seropositive hearts generally receive lifelong prophylaxis. A review of SOTs done in Spain identified 22 cases of toxoplasmosis. Although the majority of these were heart transplant recipients, kidney and liver transplant patients also developed the disease. Most of this was primary infection rather than reactivation. Being seronegative for toxoplasmosis prior to transplant was an independent risk factor for developing toxoplasmosis. This study provides new insights about toxoplasmosis in organ transplant recipients.. ...

1 the world mourned the death of Knut the polar bear, who had stolen the hearts of everyone who had visited the Berlin Zoo or who had followed his high profile career of modeling alongside celebrities like Leonardo DiCaprio. In 2012, Sussanah Calahan released her memoir Brain on Fire: My Month of Madness, which chronicled her struggle with NMDA receptor mediated-encephalitis. It was soon discovered that the same disease that Sussanah Calahan wrote about was the very disease that resulted in the death of Knut the bear. In this blog we will discuss what encephalitis is, and more specifically what NMDA receptor mediated encephalitis is. What is encephalitis?. Very simply put, encephalitis is a sudden onset inflammation of the brain or regions of the brain. While relatively rare, the incidence of the disease varies throughout the world, with approximately 7.4 new cases of acute encephalitis per 100,000 per year ...
Encephalitis is inflammation of the brain. It is usually caused by a viral infection. Examples of viral infections that can cause encephalitis include herpes simplex virus (the virus that causes cold sores and genital herpes), varicella zoster virus (the chickenpox virus), mumps virus, measles virus and flu viruses. Most cases of encephalitis are caused by the virus directly infecting the brain. However, sometimes encephalitis can develop if your immune system tries to fight off a virus and, at the same time, attacks the nerves in your brain in error. This is known as post-infectious or autoimmune encephalitis. What is the difference between encephalitis and meningitis?. Meningitis is an inflammation of the lining that covers the brain and spinal cord (the meninges). It is usually caused by a bacterial or viral infection. Sometimes you can have both encephalitis and meningitis at the same ...
Background. Well-documented outbreaks of human toxoplasmosis infection are infrequently reported. Here, we describe a community outbreak of multivisceral toxoplasmosis that occurred in Patam, a Surinamese village near the French Guianan border.. Methods. From the end of December 2003 through the middle of January 2004, 5 adult patients in Patam, including 2 pregnant women, were initially hospitalized for multivisceral toxoplasmosis. A French-Surinamese epidemiological investigation was conducted in the village; inquiries and clinical examinations were performed, and blood and environmental samples were obtained. For all serologically confirmed cases of toxoplasmosis, molecular analysis and mouse inoculations were performed for diagnosis and genetic characterization of Toxoplasma gondii.. Results. The hospitalized patients, who did not have any immunodeficiencies, presented with an infectious disease with multivisceral involvement. Serological examination confirmed acute toxoplasmosis. One adult ...
DIAGNOSIS: TOXOPLASMOSIS. DISCUSSION:. The immunohistochemical study was positive for Toxoplasma gondii demonstrating positive staining for the bradyzoites within the cysts and pseudo-cysts as well as individual tachyzoites in the necrotic tissue. Histopathological diagnosis of toxoplasmosis could be difficult due to the fact that cysts are difficult to recognize. These cysts may resemble those seen in other infections such as Leishmania donovani, Trypanosoma cruzi, Sarcocystis, Besnoitia and so on (1) Immunohistochemical stains now reveal the true nature of the microorganism, although electron microscopy can be used. Toxoplasmosis is a common CNS infection in AIDS patients (2,3). The characteristic lesion is a necrotizing acute abscess (1). Toxoplasmosis is well known as an intrauterine infection with devastating consequences but it is far more rare in settings outside of these. Although reported in post-transplanted patients, there have been virtually no reports of CNS toxoplasmosis in ...
NIH Rare Diseases : 50 ocular toxoplasmosis is an infection in the eye caused by the parasite, toxoplasm a gondii. toxoplasmosis is the most common cause of eye inflammation in the world. toxoplamosis can be acquired or present at birth (congenital), having crossed the placenta from a newly infected mother to her fetus. most humans acquire toxoplasmosis by eating raw or undercooked meat, vegetables or milk products, or by coming into contact with infected cat litterbox or sandboxes. in humans, the infection usually causes no symptoms, and resolves without treatment in a few months. in individuals with compromised immune systems, toxoplasm a gondii can reactivate to cause disease. reactivation of a congenital infection was traditionally thought to be the most common cause of ocular toxoplasmosis, but an acquired infection is now considered to be more common. a toxoplasmosis infection that affects the eye usually attacks the retina and initially resolves without symptoms. however, the inactive ...

The protozoan parasite Toxoplasma gondii (T. gondii) is an important zoonotic pathogen, which has the ability to infect all warm blooded mammals including humans, with approximately one third of the human population predicted to be infected. Transmission of the parasite to the foetus during pregnancy can result in miscarriage, however, a child infected during pregnancy may go on to develop clinical symptoms such as retinochoroiditis (ocular toxoplasmosis), hydrocephalus or learning difficulties in later life. Post-natally acquired infection in humans is generally asymptomatic, however, individuals who are immunocompromised may develop ocular toxoplasmosis or toxoplasmic encephalitis. T. gondii type II is reported to be the predominant genotype in Europe and the United States, but currently very little information exists about the prevalence and genotypes present within Great Britain. Consumption of T. gondii tissue cysts from raw or undercooked meat is a main source of ...

Toxoplasmosis is a well-known opportunistic pathogen among AIDS and immunocompromised patients including solid organ transplant recipients. It can be presented as a life threatening disease with high morbidity and mortality among these patients. Immunosuppressive treatments could reactivate latent tissue cysts and turning solid organ transplant recipients into active toxoplasmosis (11-15).. Toxoplasmosis has also been recognized as a potential donor-to-host transmission infection after solid organ transplantation mainly from seropositive heart transplant donors to seronegative recipients, as the myocardium is one of the sites were cysts of toxoplasma gondii are located (16-18).. Toxoplasmosis transmitted from the seropositive donor to seronegative recipients has also been described after liver and renal transplantation. However compare to heart transplant patients, it is much more infrequent (16). It has been reported in 57% of heart recipients, 20% of liver recipients and less than 1% in ...
We report on apparent temporal progression of probable sources of infection and transmission routes for global human toxoplasmosis outbreaks as described in published articles. We searched the Scientific Electronic Library Online, Web of Science, PubMed, and Scopus databases for articles on Toxoplasma, toxoplasmosis, and outbreaks. We found that transmission routes for Toxoplasma gondii varied by decade. In the 1960s and 1990s, toxoplasmosis outbreaks mainly occurred through ingestion of cysts in meat and meat derivatives; in the 1980s, through milk contaminated with tachyzoites; in 2000, due to the presence of oocysts in water, sand, and soil; and in 2010, due to oocysts in raw fruits and vegetables. Our study suggests a possible change in the epidemiology of reported toxoplasmosis outbreaks. Because of this change, we suggest that greater attention be paid to the disinfection of vegetables, as well as to the quality of water used for drinking and irrigation.
Encephalitis is a devastating condition whose impact upon people should not be underestimated. It robs people of abilities most of us take for granted, it leaves people without their loved ones, and even in those families where the person affected survives the person they once knew can be dramatically changed. Life After Encephalitis provides a unique insight into the experiences of those affected by encephalitis, sharing the rich, perceptive, and often powerful, narratives of survivors and family members. It shows how listening to patient and family narratives can help us to understand how they make sense of what has happened to them, and also help professionals better understand and engage with them in practice. The book will also be useful for considering narratives associated with brain injuries from other causes, for example traumatic brain injury. Life After Encephalitis will appeal to a wide range of professionals working in ...
Toxoplasmosis is a zoonotic disease with severe manifestations in HIV-positive human patients. In 1978 the overall sero-prevalence of toxoplasmosis in human patients in South Africa was found to be 20%. Toxoplasmosis in immunocompromised patients is known to be a cause of sometimes fatal complications, such as encephalomyelitis and ocular lesions. According to the literature, mutton infected with the cysts of Toxoplasma gondii is an important route of transmission to humans who ingest under-cooked meat, or eat with unwashed hands after working with meat. There is no data on the sero-prevalence in sheep in South Africa, although this is available for most other countries, including Zimbabwe. The aim of this study was to estimate the sero-prevalence of T.gondii in sheep in South Africa and to discuss the zoonotic aspects related to the prevalence of toxoplasmosis in humans. Three-stage cluster sampling was done where five different provinces randomly chosen from all the provinces in South Africa ...

A 57-year-old man with a prior episode of lymphatic toxoplasmosis presented with signs of anterior panhypopituitarism, which was confirmed by standard endocrinologic evaluation. The diagnosis of central nervous system toxoplasmosis was established by brain biopsy after nondiagnostic serologic and radiographic studies. At autopsy, the anterior pituitary was necrotic, with Toxoplasma abscesses in neighboring brain structures. Clinical and laboratory data met the criteria for the acquired immune deficiency syndrome. Although this is the first reported case of toxoplasmosis presenting as panhypopituitarism, future cases may be identified since central nervous system toxoplasmosis is being recognized more frequently in patients with immunodeficiency.
Toxoplasmosis is an infectious disease caused by the intracellular parasite Toxoplasma gondii that affects about one third of the worlds population. The diagnosis of this disease is carried out by parasite isolation and host antibodies detection. However, the diagnosis presents problems in regard to test sensitivity and specificity. Currently, the most effective T. gondii treatment is a combination of pyrimethamine and sulfadiazine, although both drugs are toxic to the host. In addition to the problems that compromise the effective diagnosis and treatment of toxoplasmosis, there are no reports or indications of any vaccine capable of fully protecting against this infection. Nanomaterials, smaller than 1000 nm, are currently being investigated as an alternative tool in the management of T. gondii infection. This article reviews how recent nanotechnology advances indicate the utility of nanomaterials in toxoplasmosis diagnosis, treatment, and ...
Toxoplasmosis is caused by the parasite Toxoplasma gondii. The infection can cause serious health problems in people with compromised immune systems. Women who become infected just before or during pregnancy may pass the parasite on to their unborn child, resulting in miscarriage, stillbirth, or an abnormally small or large head. Infection can also lead to vision loss, mental disability, seizures or other health problems later in life for the child.. Cats are most often associated with the parasite, but many other species of animals and birds also serve as hosts. The parasite also is found in people worldwide. Common symptoms of toxoplasmosis include swollen lymph nodes and flu-like symptoms.. Toxoplasmosis is considered to be a leading cause of death attributed to foodborne illness, according to the Centers for Disease Control and Prevention. More than 60 million people in the United States may be infected with Toxoplasma gondii. The parasite may be transmitted to people when they eat raw, ...
Toxoplasmosis, a neglected tropical disease caused by the protozoan parasite Toxoplasma gondii, occurs throughout the world. Human T. gondii infection is asymptomatic in 80% of the population; however, the infection is life-threatening and causes substantial neurologic damage in immunocompromised patients such as HIV-infected persons. The major purpose of this study was to investigate the seroprevalence of T. gondii infection in subjects infected with HIV/AIDS in eastern China. Our findings showed 9.7% prevalence of anti-T. gondii IgG antibody in HIV/AIDS patients, which was higher than in intravenous drug users (2.2%) and healthy controls (4.7%), while no significant difference was observed in the seroprevalence of anti-Toxoplasma IgM antibody among all participants (P,0.05). Among all HIV/AIDS patients, 15 men (7.7%) and 10 women (15.9%) were positive for anti-T. gondii IgG antibody; however, no significant difference was detected in the seroprevalence of anti-Toxoplasma IgG antibody between ...

Congenital toxoplasmosis continues to be a public health threat. Even existing guidelines, publicly known, its implementation and lack of appropriate interpretation of serological tests in pregnancy is often observed. This leds to failure in opportunities for positive and known interventions to decrease the fetal risk due to Toxoplasma gondii infection. We reported herein a case series, with variable neurological and systemic compromise (respiratory distress, hepatosplenomegaly, enterocolitis, brain calcifications, thrombocytopenia, ascites, shock), even fatal, calling for awareness about the fact that despite the Zika epidemics in 2015-2016 in Brazil, Colombia and other countries, precisely toxoplasmosis, is a differential diagnosis still prevalent in these territories, that can leds to severe consequences, with neurological disability and risk of ocular damage, even lately ...
Available drugs to treat toxoplasmosis have limitations in efficacy and can cause serious adverse effects. Moreover, toxoplasmosis is now recognized as a leading cause of foodborne illness in the United States (Scallan et al, 2011). Since a Toxoplasma vaccine for use in humans is not currently available, new classes of drugs, preferably directed against novel targets, are needed. Here we report that the benzoxaborole AN3661 inhibits Toxoplasma growth in vitro and, when orally administered to mice, is not only effective against otherwise lethal infections but also enables protective immunity against subsequent Toxoplasma infections. Genetic evidence reported herein supports the conclusion that AN3661 acts via the inhibition of a novel target of T. gondii, TgCPSF3, which is homologous to the endonuclease subunit (CPSF‐73) within the human CPSF complex that cleaves 3′‐mRNAs (Ryan et al, 2004; Mandel et al, 2006).. In another study, it is shown that AN3661 is also active against the human ...

BACKGROUND: Toxoplasmosis-related hospitalizations often occur in persons with human immunodeficiency virus (HIV) infection and other causes of immunosuppression.\n\nMETHODS: Using the National Inpatient Sample (NIS) from the Healthcare Cost and Utilization Project, we examined trends in toxoplasmosis-related hospitalizations by HIV infection status from 1993 through 2008, and rates by sex and race or ethnicity in 2008. The NIS is designed to represent a 20% sample of US community hospitals and currently includes information on up to 8 million discharges per year from ∼1000 hospitals. We used International Classification of Diseases, Ninth Revision, Clinical Modification codes 130-130.9 for toxoplasmosis and 042-044/795.8/795.71/V08 for HIV infection.\n\nRESULTS: Estimated HIV-associated toxoplasmosis hospitalizations increased from 9395 in 1993 to 10583 in 1995 (P = .0002), then dropped to 3643 in 2001 (P , .0001), with similar levels thereafter. The rate of HIV-associated toxoplasmosis ...

According to a press release issued on Wednesday, Turing Pharmaceuticals will be pushing several new drug candidates for toxoplasmosis into preclinical development. The company says the small molecular compounds are a result of Turings toxoplasmosis research efforts, with the drug candidates reportedly offering improved potency and specificity over currently-available treatments, in animal models.. Turing reports that it has started safety studies for the compounds in support of an eventual filing of an Investigational New Drug Application (IND), as part of the US Food and Drug Administrations (FDA) drug approval process. According to a statement, the company anticipates that clinical trials for the experimental drugs will begin in the second half of 2017.. "Theres a definitive need for new and improved therapies against toxoplasmosis," said Dr. Eliseo Salinas, Turings President of R&D. "Current therapies target a protein family that is required by both the parasite and its human host. ...

While the importance of Tregs in limiting T cell responses during the generation of an effector immune response to pathogens has been shown, the exact mechanisms by which Tregs limit immunopathogenic T cell responses during chronic inflammation of the brain remain unknown. We find that Tregs are recruited to the brain during toxoplasmic encephalitis, where a strong effector T cell response is necessary to limit replication of reactivated parasite. Inducible T cell costimulator (ICOS) has been shown to be both critical for developing optimal effector T cell responses to pathogens, as well as necessary for Treg survival in a homeostatic state. However, the role of ICOS signaling during the maintenance of long-term immune responses to chronic inflammation remains poorly understood. We find that Tregs recruited to the CNS during chronic infection express higher levels of ICOS than effector T cells, and that blocking ICOS signaling during chronic infection unexpectedly leads to ...
TY - JOUR. T1 - Effects of Cold Stress on Spleen Cell Proliferation and Cytokine Production during Chronic Toxoplasma gondii Infection. AU - Aviles, Hernan. AU - Johnson, Mary T.. AU - Monroy, Fernando P. PY - 2004. Y1 - 2004. N2 - Background: Cell-mediated immunity is critical for controlling infection and preventing reactivation during the chronic phase of Toxoplasma gondii infection. In people suffering from AIDS, T. gondii is one of the major opportunistic infectious agents. Mechanisms regulating rapid development of clinical signs in previously asymptomatic patients remain unclear; however, cofactors such as stress are suspected to play a role in the susceptibility to opportunistic infections. Objective: This study examined the role of cold stress (CS) in splenocyte function during chronic T. gondii infection. Methods: Control mice and mice previously infected orally with T. gondii were subjected to CS during the chronic phase (CSchr), i.e. 90 days after infection, and in vitro cell ...
Background: P35 and P22 Toxoplasma gondii proteins are recognized by specific IgG at the early infection stage, making them ideal for acute toxoplasmosis pregnancy control. Both proteins have been studied to discriminate between acute and chronic toxoplasmosis. However, results were hardly comparable because different protein obtainment procedures led to different antigens, the referencepanels used were not optimally typified, and avidity tests were either not performed or narrowly examined. Methods: We bioinformatically predicted P35 andP22 regions with the highest density of epitopes, and expressed them in pET32/BL21DE3 alternative expression system, obtaining the soluble proteins rP35a and rP22a. We assessed their diagnostic performance using pregnant woman serum samples typified as: not infected, NI (IgG−, IgM−), typical-chronic, TC (IgM−, IgG+), presumably acute, A (IgG+, IgM+, low-avidity IgG), and recentlychronic, RC (IgG+, IgM+, high-avidity IgG ...

Toxoplasmosis is an infection caused by the parasite Toxoplasma gondii. Although many people may have toxoplasma infection, very few have symptoms. This is because the immune system usually keeps the parasite from causing illness. Babies who become infected before birth can be born with serious mental or physical problems. Toxoplasmosis often causes flu-like symptoms, swollen lymph glands, or muscle aches and pains that last for a few days to several weeks. Mothers can be tested to determine if they have developed an antibody to the illness. Fetal testing may include ultrasound, and testing of amniotic fluid or cord blood. Treatment may include antibiotics. ...
Toxoplasmosis is the major parasitic disease affecting sheep. It is important for veterinary medicine, animal science and public health since it causes reproductive and economic losses in the herd, as well as damaging human health due to consumption of contaminated meat and milk, which can facilitate zoonotic transmission. Detection of Toxoplasma gondii in ovine milk and lack of data in the literature describing differentiation between acute and chronic disease for this species stimulated the elaboration of the present research project. To achieve the aim of this study, the animals were allocated to two groups of 20 ewes each, of which group 1 was composed of animals with positive serology and group 2 with negative serology. Acute and chronic stages of the disease were differentiated by modified direct agglutination test (MAT), in which antigens were fixed with formalin (MAT-AF) and methanol (MAT-AM). The parasite was detected in milk by polymerase chain reaction (PCR), and the molecular ...
Toxoplasmosis is a parasitic infection that may cause flu-like symptoms. The organism that causes toxoplasmosis - Toxoplasma gondii - is one of the worlds most common parasites. Anyone can become infected with toxoplasmosis. The parasite is found throughout the world. Toxoplasma gondii (T. gondii) is a single-celled parasitic organism that can infect most animals and birds. But because it reproduces sexually only in cats, wild and domestic felines are the parasites ultimate host.. Most people affected never develop signs and symptoms. But for infants born to infected mothers and for people with compromised immune systems, toxoplasmosis can cause extremely serious complications.. If youre generally healthy, you probably wont need any treatment for toxoplasmosis. If youre pregnant or have lowered immunity, certain medications can help reduce the infections severity. The best approach, though, is prevention.. Continue reading Toxoplasmosis →. ...
OGENDI, Edwin et al. Questionnaire Survey on the Occurrence of Risk factors for Toxoplasma gondii infection amongst Farmers in Thika District, Kenya. J. S. Afr. Vet. Assoc. [online]. 2013, vol.84, n.1, pp.00-00. ISSN 2224-9435.. A survey was conducted to determine the occurrence of risk factors for Toxoplasma gondii infection amongst farmers in Thika District, Kenya. Interviews were conducted in a total of 385 households using a structured questionnaire. The water consumed at household level originated from taps (74.3%), rivers or streams (15.1%), wells (5.4%) and boreholes (5.2%). A number of households (46.8%) consumed water without boiling or applying any form of treatment. All respondents washed vegetables before cooking, whilst 99.0% washed fruits before eating. Boiled milk was preferred by 99.5% of the farmers. The majority (85.2%) consumed beef more often, whilst 1.6% consumed pork. The majority (98.7%) consumed thoroughly cooked meat. Meat was preserved by 17% of farmers. Only four ...
The famous drawing here is by Louis Wain, an English cat artist who in his later years developed schizophrenia, which some think may have been due to toxoplasmosis caused by his prolonged exposure to cats. A recent study [1] from Walter Reed Army Institute of Research and Johns Hopkins Childrens Center, suggests that Toxoplasmosis, an infection with the Toxoplasma gondii parasite, carried by cats and farm animals, may in fact, raise the risk of a person developing schizophrenia.. Published in the January issue of the American Journal of Psychiatry, the study finds that of 180 subjects diagnosed with schizophrenia, 7 percent had been infected with toxoplasma prior to their diagnosis, as compared with 5 percent among the 532 healthy recruits.. People exposed to toxoplasma had a 24 percent higher risk of developing schizophrenia. The difference, while seemingly small, is important, researchers say, because the ability to explain even a small portion of the 2 million cases of schizophrenia in the ...

Definitive diagnosis requires cytological or histological detection of T. gondii tachyzoites in effusions, BAL fluid, CSF, aqueous humour or tissues. Sensitivity is low and increased by use of immunofluorescent/immunohistological methods, and specificity is high. In a study of 100 cases of toxoplasmosis confirmed histologically at autopsy, definitive antemortem diagnosis was made in 4% of cases only.5 Since T. gondii DNA can be amplified from blood, aqueous humour and CSF of healthy cats with latent infections, PCR assays are more useful to confirm the identity of tachyzoites/tissue cysts detected in clinical specimens. Oocyst shedding in cats can be detected by centrifugal faecal flotation using Sheathers sugar solution or zinc sulfate. Alternatively, T. gondii DNA can be detected in faeces by PCR.. Treatment. Clindamycin 12.5 mg/kg PO or IV q 12 h, or trimethoprim sulphonamide 15 mg/kg PO q 12 h, or azithromycin 10 mg/kg PO q 24 h for a minimum of 4 weeks. Pyrimethamine ...
The aim of this study was to evaluate the potential diagnostic usefulness of the full-length recombinant Toxoplasma gondii MAG1 protein by determining the levels of specific IgM and IgG antibodies in mouse and human sera obtained from individuals with acute and chronic toxoplasmosis. The obtained results revealed that IgG antibodies against MAG1 are a sensitive and specific marker of T. gondii infection since the protein was recognized by both mouse and human sera, 100% and 94.3%, respectively, rendering the full-length rMAG1 a prospective alternative for the polyvalent native antigen (TLA).. Keywords: Toxoplasma gondii, diagnostics of toxoplasmosis, ELISA, MAG1 antigen. Clinical diagnosis of Toxoplasma gondii infection, one of the most common parasitic zoonoses worldwide, relies primarily on a two-step procedure involving detection of specific antibodies (mostly IgM and IgG) and consecutive estimation of IgG avidity to distinguish between acute and chronic invasion in individuals with ...
Toxoplasmosis is caused by Toxoplasma gondii, a protozoan parasite. It can be transmitted to humans in several ways: by eating undercooked, contaminated meat or foods that have been cross-contaminated during storage or preparation; direct or indirect contact with an infected animal, particularly cats; congenital transmission from an infected mother to her unborn child; and, rarely, via contact with infected blood or transplanted organs. Healthy individuals who become infected may not have any symptoms. However, toxoplasmosis can result in serious illness and retinal lesions.

Toxoplasmosis is a cosmopolitan parasitic zoonosis, infecting human and other warm-blooded animals worldwide. This disease has economic importance in regard to animal reproduction, and it leads to abortions and neonatal complications in humans. This study was carried out to determine the seroprevalence of Toxoplasma gondii in sheep, cattle, cats and human in Inaruwa and surrounding areas of Sunsari district, Nepal. Altogether 336 blood samples, of which 50 from sheep, 92 from cattle, 44 from cats and 150 from human were collected and tested immediately using lateral fl ow chromatographic immunoassay (Toxo IgG/IgM Combo Rapid test®). Associated biometric information such as age, sex, pregnancy status, occupation, association with cat was recorded and analyzed to determine the association of risk factors with the disease. Data were analyzed using R 3.2.2 (The R foundation for Statistical Computing, 2015). Seroprevalence of toxoplasmosis was detected 12.00% (95% CI: 4.53- 24.31%) in sheep, 8.70% ...
Summary A new drug, Endochin, is reported which possesses activity against experimental toxoplasmosis. Of the sulfa derivatives tested, sulfadiazine and Promin proved to have comparable or greater effect on the infection than Endochin. Other drugs selected for their activity against the exoerythrocytic stages of malaria and which proved to be ineffective in toxoplasmosis included a sulfanilanilide (SN 187), a metanilamide (SN 11,437), a naphthoquinone (SN 8557), an 8-amino-quinoline (SN 13,276), a biguanide (SN 12,837), and an acridone (DR 15,575). Treatment combining sulfadiazine and Endochin was no more efficacious than treatment with either drug by itself.

Abstract: Purpose: To investigate whether recurrence rates of ocular toxoplasmosis are higher during pregnancy among women of childbearing age.Design: Retrospective longitudinal cohort study.Methods: We reviewed medical records of all women seen at a university eye clinic (Utrecht, Netherlands) during episodes of active toxoplasmic retinochoroiditis that occurred while the women were of childbearing age (16-42 years). Each woman was sent a questionnaire requesting information regarding all pregnancies and episodes of ocular toxoplasmosis, whether or not episodes were observed at the eye clinic. Conditional fixed-effects Poisson regression was used to model incident rate ratios of recurrence during pregnant versus non-pregnant intervals, adjusted (Read more...) Full Story →. ...
If a pregnant woman has passed the study were positive results of analyzes, toxoplasmosis can have irreparable effects on the unborn child.It should be noted that the possibility of complications is reduced in proportion to the duration of pregnancy.. If the woman was infected in the first trimester of pregnancy, there is a big risk to the fetus.In this case, the consequences could be a delay of mental or physical disabilities, congenital blindness, of the pathology of organs such as the lungs, liver, spleen.In more severe cases found fetal death or spontaneous miscarriage.Many doctors recommend abortion in case the first trimester positive results of analyzes.. Toxoplasmosis is detected in the second trimester, it carries less of a threat and more likely to be infected.However, there remains the risk of congenital heart defects, kidney problems or developmental delays.Upon receipt of positive test results in this period the doctor chooses most expectant management.This involves a thorough ...

A test to help determine whether a pregnant woman or a person with swollen lymph nodes has a recent Toxoplasma gondii infection has been cleared by the U.S. Food and Drug Administration.. The VIDAS TOXO IgG Avidity assay, manufactured by bioMérieux Inc. of Hazelwood, Mo, can be used to rule out an infection within the last four months, the FDA said in a news release.. Toxoplasmosis, caused by the parasite Toxoplasma gondii, is considered a leading cause of death attributed to foodborne illness, according to the Centers for Disease Control and Prevention. More than 60 million people in the United States may be infected with Toxoplasma gondii. The parasite may be transmitted to people when they eat raw, undercooked or contaminated meat or come in contact with infected cat feces or litter.. The infection can cause serious health problems in people with compromised immune systems. Women who become infected just before or during pregnancy may pass the parasite on to their unborn child, resulting in ...
We report here the results of our experience with the use of PCR for the identification of T. gondii in blood and aqueous humor samples from patients with and without ocular toxoplasmosis. Currently, the clinical diagnosis of ocular toxoplasmosis is based on the observation of a necrotizing lesion on the fundus, response to treatment, and serologic determination. However, in cases of atypical retinitis or when the fundus is hidden by vitreal inflammation, establishment of a diagnosis by ophthalmological examination alone can be difficult. In such cases the aqueous humor analysis may be used as a diagnostic tool for confirmation of ocular toxoplasmosis. Determination of intraocular production of antitoxoplasmic antibodies has been performed previously, but the results obtained had erratic values (2, 21). PCR has mostly been used to detect T. gondii in different biological samples (4, 9, 12, 14,19). Aqueous humor samples from patients with ocular toxoplasmosis have also been ...
Background A few studies investigated the relationship between toxoplasmosis and mental disorders, such as obsessive compulsive disorder (OCD). However, the specific nature of the association between Toxoplasma gondii (T. gondii) infection and OCD is not yet clear. The aim of this study was to collect information on the relationship between OCD and toxoplasmosis and assess whether patients with toxoplasmosis are prone to OCD. Methods For the purpose of this study, 6 major electronic databases and the Internet search engine Google Scholar were searched for the published articles up to July 30(th), 2018 with no restriction of language. The inverse variance method and the random effect model were used to combine the data. The values of odds ratio (OR) were estimated at 95% confidence interval (CI). Results A total of 9 case-control and 3 cross-sectional studies were included in our systematic review. However, 11 of these 12 articles were entered into the meta-analysis containing 9873 participants, ...

Toxoplasma gondii can infect almost all warm-blood animals including human beings. The high incidence and severe damage that can be caused by T. gondii infection clearly indicates the need for the development of a vaccine. T. gondii elongation factor 1-alpha (TgEF-1α) plays an important role in pathogenesis and host cell invasion for this parasite. The aim of this study was to evaluate the immune protective efficacy of a DNA vaccine encoding TgEF-1α gene against acute T. gondii infection in mice. A DNA vaccine (pVAX-EF-1α) encoding T. gondii EF-1a (TgEF-1α) gene was constructed and its immune response and protective efficacy against lethal challenge in BALB/c mice were evaluated. Mice inoculated with the pVAX-EF-1α vaccine had a high level of specific anti-T. gondii antibodies and produced high levels of IFN-gamma, interleukin (IL)-4, and IL-17. The expression levels of MHC-I and MHC-II molecules as well as the percentages of both CD4+ and CD8+ T cells in mice vaccinated with pVAX-EF-1α were
Toxoplasmosis, a disease of cats and other mammalian species, is caused by a parasitic protozoan, Toxoplasma gondii. Most cats show no clinical signs of infection with Toxoplasma. Occasionally, however, clinical disease toxoplasmosis occurs, kittens and young adult cats being more often affected than older animals. Lethargy, depression, loss of appetite, and fever are typical early nonspecific signs. Pneumonia, manifested by respiratory distress of gradually increasing severity, is the outstanding sign in many cats. VetPCR TOXO Detection Kit is the direct detection of Toxoplasma gondii on the basis of a genetic database, so it can diagnose very fast and accurately. It can amplify only specific gene using the PCR (Polymerase Chain Reaction) method, and take only 3hours for detection. Therefore, it is a very fast accurate and reliable technique.
Brain cyst is the most common lesion seen on a brain tomography of a patient who was admitted with any complaint; coincidentally. A brain cyst is usually benign and has been present in the patients brain since childhood. Among these benign cysts, the most common is the arachnoid cyst. These gaps filled with cerebrospinal fluid (CSF) are usually present from birth, and sometimes they can develop later on due to a trauma or infection such as meningitis.. Very rarely when they cause epilepsy or disrupt the function in the adjacent brain area; they need to be treated with a shunt operation or endoscopic procedure, as if they were a hydrocephalus case. Those who do not lead to any complaints are monitored by neurosurgeons at certain time intervals for the possibility of a change in temperament. If they grow over time or if they cause some important problems on the patients nervous system, surgery is performed. Of course, it is also very important that the patient always informs the physicians about ...
Cats can be treated with a 5-7 day course of sulphamezathine. Antimicrobials such as spiramycin, clindamycin sulphonamides, diphenylsulphones and pyrimenthamine have been shown to be effective against trophozoites and can be used against acute and chronic toxoplasmosis. In humans, the treatment of choice is pyrimethamine plus either trisulphapyrimidines or sulfadiazine. Folic acid is given to avoid the haematological effects of pyrimethamine-induced folate deficiency. Childrens play areas should be protected from cat and dog faeces. Pregnant women should take measures to prevent infection by avoiding contact with cat faeces and avoid working in soil or gardens that could be contaminated by cats, etc. and by thoroughly cooking meat. Hands should be washed after handling raw meat and before eating or touching the face. Vaccines are under development for both humans and animals. ...
Summary Toxoplasma-methylene-blue dye-test variation. Five serum samples from 20 subjects were tested for dye-test titer, the samples being drawn over a period of 16 days. This was repeated in another 20 subjects, each of whom was given one skintest dose of toxoplasmin before beginning the serum-withdrawal series. In both series the dye-test titers remained remarkably constant for each individual, and did not change after the preceding injection of toxoplasmin. This work also established the repeatability of the serologic dye-test determination. Chemotherapy of toxoplasmosis. Several antimalarial drugs were tested for effectiveness in prolonging the life of mice after infection with a highly lethal dose of Toxoplasma (RH strain). Oral or subcutaneous drug administrations were employed. None of these (Plaquenil, Aralen, and Primaquine) showed any effect. Various sulfonamide compounds, both alone and in combination with pyrimethamine, were tested as drug cures. The most effective combinations ...
There are multiple, rim-enhancing lesions within the brain parenchyma, the largest of which is centered in the region of the left caudate head. The rim of enhancement is thin in all instances, and somewhat faint. There is substantial vasogenic edema associated with each lesion, with mild mass effect upon the more anterior portion of the left lateral ventricle. There is mild cerebral atrophy.. In CNS infection by Toxoplasmosis, multiple ring-enhancing lesions are typically present, of varying size, with accompanying vasogenic edema. Nodular lesion enhancement may also be seen. In the background of HIV, cerebral atrophy is typically present. Lesions most commonly are located in the cerebral hemispheres and deep gray nuclei. The degree of enhancement of the lesions may be poor, reflecting the immune status of the patient.. ...

Toxoplasma gondii (T. gondii) and Plasmodium spp. cause toxoplasmosis and malaria respectively. Malaria affects 200 million people worldwide and kills almost half a million people every year. The biggest toll is on children of sub-Saharan Africa who suffer from deadly complications such as cerebral malaria. Toxoplasmosis poses serious risk in fetuses if contracted during pregnancy and T. gondii infection may lead to chorioretinitis or encephalitis in immunocompromised individuals. Toxoplasmosis is also a veterinarian issue with a major economical impact for the sheep industry ...
The findings suggest that toxoplasmosis, an infection from the parasite Toxoplasma gondii, may alter peoples brain chemistry to cause long-term behaviour problems. Cats are known to pass the parasite on to human by shedding its eggs in their faeces. People can become infected by not washing their hands after cleaning a cats litter tray, and then unintentionally ingesting the eggs. Around a third of people in the UK will become infected at some point in their lives - with cat owners at particularly high risk. Toxoplasmosis has also been linked with schizophrenia, bipolar disorder, impulsivity and suicidal behavior in earlier studies. The new study, published in the Journal of Clinical Psychiatry, looked at 358 adult participants. Researcher found that 22 percent of the people with IED tested positive for toxoplasmosis exposure, compared with only 9 percent of those without IED ...
PLX-4720 variation in four geographical regions ranging from as low as 8.8% to as high as 37.3%. The overall IgM positivity rate was 1.43%, indicating that an estimated 56,737C176,882 children per year are born in India having a possible risk of congenital toxoplasmosis. Author Summary Toxoplasmosis is definitely a protozoan parasitic disease generally transmitted and propagated by pet cats as family household pets. Infection acquired during pregnancy can lead to congenital abnormalities in the fetus, still birth or intrauterine death. Seroprevalence and incidence of toxoplasmosis in Indian ladies of child bearing age offers remained a contentious issue. Different laboratories have used different patient recruitment criteria, methods and variable results, making these data unreliable. There is no published pan-India seroprevalence study. Hence, a seroprevalence study was PLX-4720 undertaken comprising 1464 ladies of reproductive age representing four unique geographical regions of India. This ...
A human with an acute Toxoplasma infection experiences varying degrees of illness: fever, swollen lymph nodes, muscle stiffness, joint pain, swollen liver and/or spleen (manifested as a sore upper abdomen). These symptoms may be so mild as to go unnoticed. Illness lasts 1 to 12 weeks and is often dismissed as a bad cold or mononucleosis.However, if the person infected is a pregnant woman, the Toxoplasma organism may cross the placenta. The amount of damage done depends on the stage of pregnancy at the time of infection. Infection in mid-pregnancy may result in a child with varying degrees of blindness (due to an inflamed retina, the most common result of congenital infection) and/or various severe neurological conditions including hydrocephalus or microcephaly. Sometimes problems are not evident at birth and show up later in life. The problems described above occur when a woman, who happens to be pregnant, is infected with Toxoplasma for the first time. Only the new stages of infection cause ...
An opportunistic illness requires impairment of host defenses, which may manifest on account of genetic defects (which include Long-term granulomatous illness), exposure to antimicrobial drugs or immunosuppressive chemical compounds (as might manifest adhering to poisoning or cancer chemotherapy), exposure to ionizing radiation, or because of an infectious ailment with immunosuppressive action (these types of as with measles, malaria or HIV disease). Principal pathogens may also induce more serious ailment in a host with frustrated resistance than would normally come about within an immunosufficient host.[nine ...
