How people affected by Chagas disease have struggled with their negligence: history, associative movement and World Chagas Disease Day.

It is well documented that Chagas disease (CD) can pose a public health problem to countries. As one of the World Health Organization Neglected Tropical Diseases undoubtedly calls for comprehensive healthcare, transcending a restricted biomedical approach. After more than a century since their discovery, in 1909, people affected by CD are still frequently marginalised and/or neglected.

Mapping the morbidity and mortality of Chagas disease in an endemic area in Brazil.

Chagas disease is among the 21 neglected diseases according to the World Health Organization. This study aimed to investigate the morbidity and mortality distribution of Chagas disease for identifying areas with greater prevalences and deaths of the disease in Northeast Brazil. A population-based ecological study was performed from 2016 to 2018 using data on acute Chagas disease patients from the Disease Notification Information System, chronic cases from the Chagas Disease and the referral Heart Failure Outpatient Clinic in Pernambuco, and Chagas disease-related mortality from the Mortality Information System.

Influence of Angiotensin-converting Enzyme Insertion/Deletion Gene Polymorphism in Progression of Chagas Heart Disease.

Introduction: Chagas disease (CD) is a neglected disease caused by the parasite Trypanosoma cruzi. One-third of infected patients will develop the cardiac form, which may progress to heart failure (HF). However, the factors that determine disease progression remain unclear.

Single nucleotide polymorphisms of cytokine-related genes and association with clinical outcome in a Chagas disease case-control study from Brazil.

Background: The severity of chronic chagasic cardiomyopathy (CCC), the most frequent clinical outcome of Chagas disease (CD), has been associated with cytokine-enriched heart tissue inflammation, and high serum levels of transforming growth factor (TGFβ), interferon-gamma (IFNγ), and tumour necrosis factor (TNF). Conversely, increased interleukin (IL)-10 serum concentrations have been associated with asymptomatic CD. Cytokines and cytokine-related gene polymorphisms may control cytokine expression and have been proposed to contribute to CCC outcomes.

Genetic Polymorphism at Is Associated With Protection in Chagas' Heart Disease: Antagonistic Participation of CCR1 and CCR5 Cells in Chronic Chagasic Cardiomyopathy.

Chronic cardiomyopathy is the main clinical manifestation of Chagas disease (CD), a disease caused by infection. A hallmark of chronic chagasic cardiomyopathy (CCC) is a fibrogenic inflammation mainly composed of CD8 and CD4 T cells and macrophages. CC-chemokine ligands and receptors have been proposed to drive cell migration toward the heart tissue of CD patients.
