Onchocerciasis News and Research

RSS

Onchocerciasis is a parasitic disease caused by the filarial worm Onchocerca volvulus. It is transmitted through the bites of infected blackflies of Simulium species, which carry immature larval forms of the parasite from human to human. In the human body, the larvae form nodules in the subcutaneous tissue, where they mature to adult worms. After mating, the female adult worm can release up to 1000 microfilariae a day. These move through the body, and when they die they cause a variety of conditions, including blindness, skin rashes, lesions, intense itching and skin depigmentation. Onchocerciasis is endemic in more than 25 nations located in a broad band across the central part of Africa. Small endemic foci are also present in the Arabian Peninsula (Yemen) and in the Americas (Brazil, Colombia, Ecuador, Guatemala, southern Mexico, and Venezuela).

Heartworm medication Ivermectin prevents malaria transmission in Africa

A cheap, common heartworm medication that is already being used to fight other parasites in Africa could also dramatically interrupt transmission of malaria, potentially providing an inexpensive tool to fight a disease that kills almost 800,000 people each year, according to a new study published in the July edition of the American Journal of Tropical Medicine and Hygiene.

Merck proposes to initiate Phase II proof-of-concept clinical study of posaconazole for chronic Chagas disease

Merck today announced plans to initiate a Phase II investigational proof-of-concept clinical study to evaluate its oral antifungal agent posaconazole for the treatment of chronic Chagas disease. Chagas disease results from infection with the parasite Trypanosoma cruzi that is spread by biting insects. The disease is estimated to affect approximately eight million people in Latin America, of whom approximately 30-40 percent will develop serious cardiac disease, digestive disease, or both as a result of this infection.
