What is the drug of choice for African trypanosomiasis?
Pentamidine, the recommended drug for first stage T. b. gambiense infection, is available in the United States.
What is the difference between African trypanosomiasis and American trypanosomiasis?
African trypanosomiasis, or sleeping sickness, is caused by Trypanosoma brucei parasites in sub-Saharan Africa and is transmitted by the tsetse fly? (Glossina). American trypanosomiasis, or Chagas disease, is caused by Trypanosoma cruzi parasites in Latin America and is transmitted by the triatomine or ‘kissing’ bug.
Is there a vaccine for Chagas disease?
Currently, there is no vaccine to prevent Chagas disease and chemotherapy is the only alternative for curing infected individuals. The success of treatment depends on stage of the disease, age of the patient and biochemical characteristics of the parasite strain (WHO, 2017).
Can trypanosomiasis be treated?
The acute phase of trypanosomiasis (Chagas disease) is treated with nifurtimox or benznidazole. Cases of congenital Chagas disease have been successfully treated with either drug. A single case of successful treatment of an adult with posaconazole (after failure of therapy with benznidazole) has been reported.
What is the pathophysiology of African trypanosomiasis?
Human African trypanosomiasis is a disease that evolves through clinically distinct stages, with a lethal outcome if left untreated. The first symptoms begin at the site of the tsetse fly’s bite after a minimum of five days. This local skin reaction is called a trypanosomal chancre.
What drugs are used to treat African trypanosomiasis?
The range of drugs that are used against human African trypanosomiasis is limited (box (boxB1).B1). Only one of them is less than 40 years old. Until recently melarsoprol, a compound containing arsenic, was the only treatment readily available for stage 2 disease, but it is associated with 4% to 12% mortality.
How is trypanosomiasis diagnosed and treated?
Diagnosis and treatment of the disease is complex and requires specifically skilled staff. Human African trypanosomiasis, also known as sleeping sickness, is a vector-borne parasitic disease. It is caused by infection with protozoan parasites belonging to the genus Trypanosoma.
How is trypanosomiasis transmitted from mother to child?
The disease is mostly transmitted through the bite of an infected tsetse fly but there are other ways in which people are infected: Mother-to-child infection: the trypanosome can cross the placenta and infect the fetus.
