  • Neglected Parasitic Infections in the United States Toxoplasmosis
    Neglected Parasitic Infections in the United States Toxoplasmosis Toxoplasmosis is a preventable disease caused by the parasite Toxoplasma gondii. An infected individual can experience fever, malaise, and swollen lymph nodes, but can also show no signs or symptoms. A small number of infected persons may experience eye disease, and infection during pregnancy can lead to miscarriage or severe disease in the newborn, including developmental delays, blindness, and epilepsy. Once infected with T. gondii, people are generally infected for life. As a result, infected individuals with weakened immune systems—such as in the case of advanced HIV disease, during cancer treatment, or after organ transplant—can experience disease reactivation, which can result in severe illness or even death. In persons with advanced HIV disease, inflammation of the brain (encephalitis) due to toxoplasmosis is common unless long-term preventive medication is taken. Researchers have also found an association of T. gondii infection with the risk for mental illness, though this requires further study. Although T. gondii can infect most warm-blooded animals, cats are the only host that shed an environmentally resistant form of the organism (oocyst) in their feces. Once a person or another warm-blooded animal ingests the parasite, it becomes infectious and travels through the wall of the intestine. Then the parasite is carried by blood to other tissues including the muscles and central nervous system. Humans can be infected several ways, including: • Eating raw or undercooked meat containing the parasite in tissue cysts (usually pork, lamb, goat, or wild game meat, although beef and field-raised chickens have been implicated in studies).

However, toxoplasmosis can be severe and even fatal in immunocompromised patients and fetuses. Available treatment options are limited, so there is a strong impetus to develop novel therapeutics. This review focuses on the role of oxidative stress in the pathophysiology and treatment of T. gondii infection. Chemical compounds that modify redox status can reduce the parasite viability and thus be potential anti-Toxoplasma drugs. On the other hand, oxidative stress caused by the activation of the inflammatory response may have some deleterious consequences in host cells. In this respect, the potential use of natural antioxidants Citation: Szewczyk-Golec, K.; is worth considering, including melatonin and some vitamins, as possible novel anti-Toxoplasma Pawłowska, M.; Wesołowski, R.; therapeutics. Results of in vitro and animal studies are promising. However, supplementation with Wróblewski, M.; Mila-Kierzenkowska, some antioxidants was found to promote the increase in parasitemia, and the disease was then C.

Gale1,2, Andrew N. Berrett1, Bruce Brown1, Lance D. Erickson3 and Dawson W. Hedges1,2 1 Department of Psychology, Brigham Young University, Provo, Utah, USA; 2 The Neuroscience Center, Brigham Young University, Provo, Utah, USA; 3 Department of Sociology, Brigham Young University, Provo, Utah, USA Abstract: Changes in behaviour and cognition have been associated with latent infection from the apicomplexan protozoan Toxoplas- ma gondii (Nicolle et Manceaux, 1908) in both animal and human studies. Further, neuropsychiatric disorders such as schizophrenia have also been associated with latent toxoplasmosis. Previously, we found no association between T. gondii immunoglobulin G anti- body (IgG) seropositivity and depression in human adults between the ages of 20 and 39 years (n = 1 846) in a sample representative of the United States collected by the Centers for Disease Control as part of a National Health and Nutrition Examination Survey (NHANES) from three datasets collected between 1999–2004. In the present study, we used NHANES data collected between 2009 and 2012 that included subjects aged 20 to 80 years (n = 5 487) and used the Patient Health Questionnaire 9 (PHQ-9) to assess depres- sion with the overall aim of testing the stability of the results of the prior study. In the current study, the seroprevalence of T. gondii was 13%. The percentage of subjects reporting clinical levels of depression assessed with the PHQ-9 was 8%.

T. gondii can lead to serious diseases in immuno-compromised patients such as HIV/AIDS patients. In most cases, central nervous system involvement can lead to encephalitis, which is one of the most important reasons for death among patients with HIV due to reactivation of tissue cysts that remained latent after the primary infection. This study was conducted to assess the sero burden of Toxoplasma gondii infection and identify associated risk factors among HIV infected individuals in Armed Forces Referral and Teaching Hospital, Addis Ababa, Ethiopia. Methods: A cross-sectional study was conducted from March to May 2016. After getting an informed consent a pretested questionnaire was used to gather socio-demographic information and data on factors predisposing to T.

Several antiviral drugs are approved to treat HCMV infections. However, resistant HCMV mutants can arise in patients receiving long-term therapy. Additionally, side effects and the risk to cause birth defects limit the use of currently approved antivirals against HCMV. Therefore, the identification of new drug targets is of clinical relevance. Recent work identified DNA-damage binding protein 1 (DDB1) and the family of the cellular cullin (Cul) RING ubiquitin (Ub) ligases (CRLs) as host-derived factors that are relevant for the replication of human and mouse cytomegaloviruses. The first-in-class CRL inhibitory compound Pevonedistat (also called MLN4924) is currently under investigation as an anti-tumor drug in several clinical trials. Cytomegaloviruses exploit CRLs to regulate the abundance of viral proteins, and to induce the proteasomal degradation of host restriction factors involved in innate and intrinsic immunity. Accordingly, pharmacological blockade of CRL activity diminishes viral replication in cell culture.
