Abstract
The aim of this review was to identify anti-inflammatory and antioxidant therapeutic agents and their effects on patients with chagasic myocarditis. A systematic review of the MEDLINE, EMBASE, WEB OF SCIENCE, SCOPUS, LILACS and CENTRAL databases (Cochrane Library) was carried out without language restrictions. The descriptors used were: ‘Chagas cardiomyopathy’, ‘treatment’, ‘Chagas disease’, ‘anti-inflammatory agents’, ‘Trypanosoma cruzi’ and ‘antioxidants’. A total of 4,138 articles was identified, six of which were selected for data extraction. Of these, four were related to antioxidant therapy with vitamins C and E supplementation, and two using anti-inflammatory therapy. The studies were carried out in Brazil and were published between 2002 and 2017. Antioxidant therapy with vitamin C and E supplementation increases the activity of antioxidant enzymes and reduces the oxidative markers. There is no conclusive data to support the use of vitamin supplementation and anti-inflammatory therapy in the treatment of chagasic cardiomyopathy. However, the studies indicate the possibility of vitamin supplementation as a new approach to the treatment of Chagas disease. Antioxidant therapy was proven to be a viable alternative for attenuating the oxidative damage caused by chronic chagasic cardiopathy, leading to a better prognosis for patients.
