1. Evaluation of functionality in children aged 4-6 years presenting congenital toxoplasmosis and retinochoroiditis
Resumo Introdução: No Brasil, a toxoplasmose congênita (TC) é a principal causa de deficiência visual na infância. É causa de retinocoroidite, que pode levar à cegueira. Minas Gerais apresenta prevalência de um neonato com TC para cada 770 nascidos vivos. Objetivo: Avaliar funcionalidade visual e tarefas do autocuidado de crianças com TC classifi

2. Serum levels of neurotrophic factors in active toxoplasmic retinochoroiditis
Abstract Toxoplasmic retinochoroiditis (TR) is the most common identifiable cause of posterior uveitis in Brazil. Response to treatment and clinical presentation may vary significantly. We assessed serum levels of brain-derived neurotrophic factor (BDNF), glial cell line-derived neurotrophic factor (GDNF), nerve growth factor (NGF), neurotrophin (NT)-3, and

3. The performance of four molecular methods for the laboratory diagnosis of congenital toxoplasmosis in amniotic fluid samples
Introduction Toxoplasmosis may be life-threatening in fetuses and in immune-deficient patients. Conventional laboratory diagnosis of toxoplasmosis is based on the presence of IgM and IgG anti-Toxoplasma gondii antibodies; however, molecular techniques have emerged as alternative tools due to their increased sensitivity. The aim of this study was to compare

4. Increased serum levels of soluble tumor necrosis factor receptor-2 (sTNFR2) in patients with active toxoplasmic retinochoroiditis
This study aimed to investigate the serum levels of the cytokine TNF-α and its soluble receptors (sTNFR1 and sTNFR2) in patients with toxoplasmosis retinochoroidits (TR) and controls. 37 patients with TR and 30 subjects with positive serology for toxoplasmosis but without history and signs of uveitis were included in this study. Serum concentrations of TNF-

5. Risk factors for Toxoplasma gondii infection and development of toxoplasmic retinochoroiditis. / Fatores de risco para infecção por Toxoplasma gondii e desenvolvimento da retinocoroidite toxoplásmica.
Toxoplasma gondii (T. gondii) infecta os seres humanos dentre outras vias, pelo trato gastrintestinal, local de expressão dos antígenos ABO por meio de interações epistáticas entre os genes ABO, Secretor e Lewis. A retinocoroidite toxoplásmica (RT), doença resultante desta infecção, é considerada a principal causa de uveíte posterior. Objetivo: Av

6. Disseminated toxoplasmosis in an immunocompetent patient from Peruvian Amazon
We report a case of severe toxoplasmosis in an immunocompetent patient, characterized by pneumonia, retinochoroiditis, hepatitis and myositis. Diagnosis was confirmed by serology, T. gondii in thick blood smear and presence of bradyzoites in muscle biopsy. Treatment with pyrimethamine plus sulfadoxine was successful but visual acuity and hip extension were p

7. Candidate gene analysis of ocular toxoplasmosis in Brazil: evidence for a role for toll-like receptor 9 (TLR9)
Toxoplasma gondii infection is an important mediator of ocular disease in Brazil more frequently than reported from elsewhere. Infection and pathology are characterized by a strong proinflammatory response which in mice is triggered by interaction of the parasite with the toll-like receptor (TLR)/MyD88 pathway. A powerful way to identify the role of TLRs in

8. The IFN-³+874T/A gene polymorphism is associated with retinochoroiditis toxoplasmosis susceptibility
Toxoplasmosis is a worldwide zoonosis that generally produces an asymptomatic infection. In some cases, however, toxoplasmosis infection can lead to ocular damage. The immune system has a crucial role in both the course of the infection and in the evolution of toxoplasmosis disease. In particular, IFN-³ plays an important role in resistance to toxoplasmosis

9. Ocular toxoplasmosis: the influence of patient age
The influence of patient age on various features of ocular toxoplasmosis has been a subject of study for many years. The age at which Toxoplasma gondii infection occurs in different populations is related to socioeconomic factors and studies suggest that ocular toxoplasmosis is a more severe disease at the extremes of age. The prevalence of ocular involvemen

10. Acute acquired toxoplasmosis: clinical-laboratorial aspects and ophthalmologic evaluation in a cohort of immunocompetent patients
Most cases of acute acquired toxoplasmosis (AAT) are oligosymptomatic and self-limited. Therefore, these infections rarely indicate treatment. Prospective studies of AAT patients are rare in the medical literature. The frequency of systemic manifestations has not been sufficiently studied. In order to search for risks factors for systemic and ocular involvem

11. Treating ocular toxoplasmosis: current evidence
The current treatment of ocular toxoplasmosis is controversial. The mainstay of treatment has been pyrimethamine and sulphonamides with or without systemic corticosteroids, but the actual evidence that antibiotics have a beneficial effect in recurrent toxoplasmic retinochoroiditis is unsupported by randomised placebo controlled trials. Thus far there have on

12. DinÃmica da IgA secretora especÃfica na lÃgrima empacientes portadores de uveÃte posterior ativa presumivelmente por Toxoplasma gondii durante o primeiro trimestre da doenÃa
Toxoplasma gondii (T.gondii) is the main cause of posterior uveitis and toxoplasmic retinochoroiditis is considered the most common infection of the retina. Serological tests are important tools for the diagnosis of toxoplasmosis, but in ocular toxoplasmosis, usually there is no correlation between levels of serum antibodies and eye symptoms in the patient.
