Received: 28 June 2012; in revised form: 14 July 2012 / Accepted: 16 July 2012 / Published: 27 July 2012 Abstract: Autophagy is a ubiquitous eukaryotic process that also occurs in trypanosomatid parasites, protist organisms belonging to the supergroup Excavata, distinct from the supergroup Opistokontha that includes mammals and fungi. Half of the known yeast and mammalian AuTophaGy (ATG) proteins were detected in trypanosomatids, although with low sequence conservation. Trypanosomatids such as Trypanosoma brucei, Trypanosoma cruzi and Leishmania spp. are responsible for serious tropical diseases in humans. The parasites are transmitted by insects and, consequently, have a complicated life cycle during which they undergo dramatic morphological and metabolic transformations to adapt to the different environments.

The objective of meetings of the PAAT Committee is, on the basis of technical and scientific advice forwarded from the Advisory Group Co-ordinators and the Liaison Officers, to provide the focus for collaborative efforts to alleviate trypanosomiasis in Africa. Discussions at the current meeting were largely devoted to matters arising from the meeting of the PAAT Advisory Group Co-ordinators convened in Harare, Zimbabwe, October 1998 (see TTIQ, 21 (4)). Progress since the last meeting was reviewed. This included: ISCTRC representation on the Programme Committee and increased donor involvement; considerable progress on the development of the information systems for both animal and human trypanosomiasis (both the prototype PAAT-IS for animal trypanosomiasis and the CD-ROM-based information system developed by WHO for the human disease were demonstrated and the need for cross-linkages between the two was stressed); evaluation of the socio-economic impact of trypanosomiasis and the identification of priority control strategies; development of position papers on technical and policy aspects of the PAAT following open discussion via e-mail (that on drug resistance having been published as the first in the new PAAT Technical and Scientific Series); production and distribution of a glossy brochure announcing PAAT; and initiation of a quarterly PAAT Newsletter.

  • The Trypanosomiases
    SEMINAR Seminar The trypanosomiases Michael P Barrett, Richard J S Burchmore, August Stich, Julio O Lazzari, Alberto Carlos Frasch, Juan José Cazzulo, Sanjeev Krishna The trypanosomiases consist of a group of important animal and human diseases caused by parasitic protozoa of the genus Trypanosoma. In sub-Saharan Africa, the final decade of the 20th century witnessed an alarming resurgence in sleeping sickness (human African trypanosomiasis). In South and Central America, Chagas’ disease (American trypanosomiasis) remains one of the most prevalent infectious diseases. Arthropod vectors transmit African and American trypanosomiases, and disease containment through insect control programmes is an achievable goal. Chemotherapy is available for both diseases, but existing drugs are far from ideal. The trypanosomes are some of the earliest diverging members of the Eukaryotae and share several biochemical peculiarities that have stimulated research into new drug targets. However, differences in the ways in which trypanosome species interact with their hosts have frustrated efforts to design drugs effective against both species. Growth in recognition of these neglected diseases might result in progress towards control through increased funding for drug development and vector elimination. Parasitic protozoa infect hundreds of millions of people similarities and discrepancies in their biology, the diseases every year and are collectively some of the most important they cause, and approaches to their treatment and control. causes of human misery. The protozoan order Kineto- plastida includes the genus Trypanosoma, species that cause The parasites and their vectors some of the most neglected human diseases. Superficially, there are many similarities between There are many species of trypanosome, and the group trypanosome species and the diseases they cause (table).

  • Sleeping Sickness)
    NEUROLOGICAL PROGRESS The Continuing Problem of Human African Trypanosomiasis (Sleeping Sickness) Peter G. E. Kennedy, MD, PhD, DSc Human African trypanosomiasis, also known as sleeping sickness, is a neglected disease, and it continues to pose a major threat to 60 million people in 36 countries in sub-Saharan Africa. Transmitted by the bite of the tsetse fly, the disease is caused by protozoan parasites of the genus Trypanosoma and comes in two types: East African human African trypanosomiasis caused by Trypanosoma brucei rhodesiense and the West African form caused by Trypanosoma brucei gambiense. There is an early or hemo- lymphatic stage and a late or encephalitic stage, when the parasites cross the blood–brain barrier to invade the central nervous system. Two critical current issues are disease staging and drug therapy, especially for late-stage disease. Lumbar puncture to analyze cerebrospinal fluid will remain the only method of disease staging until reliable noninvasive methods are developed, but there is no widespread consensus as to what exactly defines biologically central nervous system disease or what specific cerebro- spinal fluid findings should justify drug therapy for late-stage involvement. All four main drugs used for human African trypano- somiasis are toxic, and melarsoprol, the only drug that is effective for both types of central nervous system disease, is so toxic that it kills 5% of patients who receive it. Eflornithine, alone or combined with nifurtimox, is being used increasingly as first-line therapy for gambiense disease. There is a pressing need for an effective, safe oral drug for both stages of the disease, but this will require a significant increase in investment for new drug discovery from Western governments and the pharmaceutical industry.
