We report the first case series of children in Mexico living with symptomatic Chagas disease causing chronic myocardopathy. The findings suggest that children with Chagas disease may develop symptomatic chronic myocardopathy earlier than previously recognized. Our findings emphasize the importance of longitudinal cardiologic follow-up of all children identified with acute Chagas disease.In a cohort of 826 children from the state of Queretaro in Mexico, 11 were identified with positive serology (ELISA and IFI) for Chagas and were tested for electrocardiogram alterations and symptoms and signs. Four children had ECG alterations with 3 of these reporting signs and symptoms associated with the chronic phase of Chagas disease (27%; 95% CI: 6%-61%). The most common chronic symptom was chest pain, with one child also reporting dyspnea and tachycardia.

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.

Background: Nurses provide essential care for symptomatic chronic Chagas disease carriers, caused by Trypanosoma cruzi, offering crucial support, symptom management, medication administration, and monitoring to enhance their health-related quality of life.
Objective: To increase healthcare professionals' awareness of the critical role played by high-quality care in the management of patients with chronic Chagas disease.
Methods: This scoping review employed the PRISMA-ScR method as a framework for article selection.
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.
