Abstract :

Chagas disease burdens millions of people in Latin America (22% congenital) and threatens those in Southern States and California as an emerging disease in USA Trypanosoma Cruzi (T. Cruzi) is important cause of gastrointestinal and cardiovascular disease. It is transmitted by Triatoma vector, congenital and sexual or via blood transfusion. Acute infectious inflammatory disease is accompanied by a chronic asymptomatic stage; however, 20% to 40% of infected individuals ultimately develop chronic cardiomyopathy and megacolon due to immunosuppression or aging. Center for Disease Control (CDC) reports Chagas as a hidden public health risk with over 300,000 people living in U.S.A borders (>30,000 in Los Angeles) to be infected with T. cruzi. Amongst 2000 cardiac surgeries in Houston, TX 0.05% cases and 2.7% of Hispanic patients were found to be infected mostly due to contaminated blood transfusion. In Brazil about 5% of HIV patients had a coinfection with T. Cruzi. Chagas coinfection in AIDS/HIV patients manifests as central nervous system involvement which is detected mostly after death. Toxoplasmosis is another opportunistic organism with an estimated 1.5 billion people globally predicted to be infected. Toxoplasmosis is one of the most important congenital disorders, inflammatory syndromes as well as foodborne illnesses and hospitalization. Toxoplasma is transmitted by contaminated food and animal products (cysts form), water, fruits, vegetables (oocysts), maternally or sexually acquired through semen (tachyzoites). Toxoplasmosis is also a neglected disease of poverty and prominent in rural areas. Similar to T. Cruzi, Toxoplasma causes a complex immune-inflammatory reaction in vital organs with the surge of chemokines and cytokines. Subsequent acute phase, the organisms lodge in cyst forms predominantly in muscles and CNS awaiting reactivation due to immunosuppression or AIDS/HIV. Toxoplasma infects all nucleated cells with a specific tropism for central nervous system and a mind altering, psycho-behavior and fatal attraction. Toxoplasma impairs neurons responsible for instinct defensive and judgment behaviors adjacent to limbic regions of sexual desire. Pregnant mom with newly acquired acute or reactivated toxoplasmosis transmits organism via placenta to her fetus with grave life threatening consequences. Current available therapies are inefficient or have severe side effects in congenital and chronic toxoplasmosis. There is an urgent need for safe and effective therapeutic modalities against toxoplasmosis as well as possible effective vaccines to eliminate the infectious agents in definitive host. This presentation will include some of the speaker��?s investigations in the field as well as transmission, immunomodulation, and pathogenesis of Chagas and toxoplasmosis; to discuss current available treatments in practice, and to explore experimental therapies for potential future clinical trials.
