Summary
Two agricultural workers in Brazil had persistent mucosal leishmaniasis caused by Leishmania (Viannia) braziliensis. Their extensive upper respiratory symptoms did not improve with standard or experimental treatments, highlighting treatment challenges.
Area of Science:
- Tropical medicine
- Parasitology
- Infectious diseases
Background:
- Mucosal leishmaniasis is a significant public health concern in Brazil.
- Leishmania (Viannia) braziliensis is a primary cause of leishmaniasis in South America.
- Treatment resistance is a growing challenge in managing leishmaniasis.
Observation:
- The study followed two male agricultural workers from Bahia State, Brazil.
- Both patients presented with severe upper respiratory mucosal leishmaniasis.
- The condition was unresponsive to multiple conventional and experimental therapies.
Findings:
- Long-term clinical follow-up revealed persistent disease activity.
- Lack of therapeutic response was observed despite various treatment regimens.
- The cases underscore the difficulties in treating certain forms of leishmaniasis.
Implications:
- These findings highlight the need for novel therapeutic strategies for drug-resistant leishmaniasis.
- Further research into the pathogenesis of Leishmania (Viannia) braziliensis is warranted.
- Improved diagnostic and treatment protocols are crucial for patient outcomes in endemic regions.

01:30Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
01:21Antiprotozoal Agents
Leishmaniasis is a widespread parasitic disease caused by several Leishmania species. It affects millions of people each year and remains a major public health problem in endemic regions. First-line treatment relies on pentavalent antimonials, including meglumine antimoniate and sodium stibogluconate. Even so, how these drugs work has not been fully clear, especially their interaction with parasite-specific biochemical pathways. One key target is trypanothione reductase (TR), an enzyme that...
