Background: Chagas' disease is an endemic tropical affliction found from southern United States to Argentina. The acute phase of this disease is difficult to study in man because the symptoms are non-specific and most cases require no medical assistance. Experimental models have been developed for sequential studies, and intense parasitism in all organs and tissues, including the pancreas, have been detected in the acute phase.
Purpose: To evaluate the involvement of the pancreas in acute experimental Chagas' disease in a mouse model by histopathological characterization.
Casuistic And Methods: Ten BALBc mice, about 20 g, injected i.p. with 100 000 forms of the Y strain of Trypanosoma cruzi were used. The animals were sacrificed after 14 days of infection. Fragments of pancreas were processed by conventional paraffin embedding and hematoxylin-eosin staining.
Results: Ruptured pseudocysts and release of parasites to the extracellular medium caused by necrosis of acinar and duct cells and foci of fat were the most striking histopathological features of acute Chagasic pancreatitis.
Conclusion: Parasitism is the main cause of acute pancreatitis in Chagas' disease.

Discovery of a Potent Triazole-Based Reversible Targeted Covalent Inhibitor of Cruzipain.

Cruzipain (CZP) is an essential cysteine protease of , the etiological agent of Chagas disease, and a promising druggable target. To date, no CZP inhibitors have reached clinical use, with research efforts mostly hampered by insufficient potency, limited target selectivity or lack of bioactivity translation from the isolated enzyme to the parasite in cellular environments. In this study, we report the design of , a 1,2,3-triazole-based targeted covalent inhibitor with nanomolar potency (IC = 28 nM) and null inhibition of human cathepsin L.

Background: Endemic in more than 20 countries, Chagas disease affects 6.3 million people worldwide, leading to 28,000 new infections and 7700 deaths each year. Previous meta-analyses on antiparasitic treatment need updates to encompass recent studies and to assess key clinically meaningful endpoints.

Eco-epidemiological Survey of Trypanosoma cruzi in Dogs from Mendoza, Argentina.

Urban domestic dog populations can provide important clues about the eco-epidemiological characteristics of Trypanosoma cruzi, the causative agent of Chagas disease (ChD). Given the limited data on ChD from the Metropolitan Area of Mendoza, Argentina, a seroprevalence survey of 327 dogs across an urban-rural gradient was conducted between April 2018 and May 2019. Seropositive cases were analyzed considering host, social, and environmental factors, subtypes (DTUs), and bloodstream parasite load.

Background: Determining esophageal and colon involvement in patients with Chagas disease occurs through invasive and uncomfortable examinations, which in most cases are not performed. The objective of this study was to assess the involvement of anti-M2-pyruvate kinase (M2-PK) autoantibodies in the development of digestive alterations and/or in the diagnosis of the digestive form of human Chagas disease.
Methods: The total IgG and isotype (IgG1, IgG2, IgG3, IgG4) production was quantified using the antigen of Trypanosoma cruzi and the human M2-PK recombinant protein via the ELISA technique.
