Chagas Disease in Pregnant Women from Endemic Regions Attending the Hospital General de Mexico, Mexico City.

ABSTRACT: Trypanosoma cruzi infection leads to Chagas disease (CD), a neglected tropical infection of significant public health importance in South and Central America and other, non-endemic, countries. Pregnant women and their children are of particular importance to screen as T. cruzi can be transmitted vertically. The objective of this study was to screen for T. cruzi infection among pregnant women from endemic areas seen at the Hospital General de Mexico for prenatal care, so that they and their children may be quickly connected to CD treatment. Pregnant women were recruited through the hospital prenatal clinic and screened for T. cruzi infection using a series of serological and molecular tests. Of 150 screened patients, mean age 26.8 (SD 6.4), 30 (20.0%) were positive by at least one diagnostic test. Of these, only nine (6%) were positive as determined by PCR. Diagnosis of chronic CD is difficult in endemic places like Mexico due to the limitations of current commercially available diagnostic tests. Further evaluation of diagnostic performance of various assays could improve current CD diagnostic algorithms and proper care management in these regions. Genetic variability in the parasite may also play a role in the differing assay performances seen in this study, and this may be a valuable avenue of further research.

Project description:BackgroundOn an absolute basis, Argentina is the country with the largest affected population with Chagas Disease (ChD). This constitutes a significant public health issue. As a consequence of Argentina's migratory patterns, there has been a significant increase of affected population in urban centers. An innovative project for early diagnosis and timely treatment of ChD was designed for Municipal Primary Care Facilities of La Plata City, a non- endemic area, in line with a proposal from the Pan-American Health Organization. The project was a public -private intervention. The objectives of this study were to demonstrate the feasibility of the primary healthcare level for early diagnosis and timely treatment of ChD; to design and implement a tailor made program and to innovate in a public-private association.MethodsThe healthcare barriers for early diagnosis and timely treatment for the population with ChD of La Plata were analyzed. The four dimensions described by Peters et al. (Ann N Y Acad Sci 1136:161-71, 2008) were used. The baseline was measured during a previous pilot project and the same items were evaluated at the end of 2017. The model from Damschroder et al. (Implement Sci 4:50, 2009) was used during the implementation process.ResultsWith all the information gathered during this investigation, a "patient-centered" model was designed. During the program, 17,894 people were serologically tested for ChD, 1,394 were positive and 1,035 were treated. Additionally, 3,750 children from 46 public schools were evaluated for risk factors of ChD.ConclusionsThis project showed the feasibility of the primary healthcare level for early diagnosis and timely treatment of ChD. Tailor made programs and public-private associations should be considered for vulnerable populations in emerging economies in order to enhance efforts and obtain better results. This program may be replicated in other countries of Latin America were Chagas is a main public health issue and, with the corresponding adaptations, for other neglected diseases as well.
