Effects of Highly Diluted Drugs on Experimental Infection with : Systematic Review.

To investigate, through a systematic review, the effects of the use of highly diluted drugs in the treatment of experimental infection with . The authors searched for scientific publications in the databases PubMed, Web of Science, SCOPUS, LILACS, and the Google Scholar search system, from 2000 to 2018, following the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statement. According to the criteria established, a total of 22 studies were included. The study took place at the State University of Maringá, Maringá, PR, Brazil. Male mice () or rats (). Highly diluted drugs. The parameters evaluated in the studies were parasitological, clinical, immunological, histopathological and hematological. The studies demonstrated that the effects of highly diluted drugs are related to their dynamizations, treatment regimen, and host susceptibility to infection, and depend on the initial information transmitted to the treated organism, making this information the "model" of how the treated organism will react. Regardless of the mechanism of action, these drugs provide a decrease in inflammation, which is one of the central phenomena of the pathogenesis of infection. This systematic review brings out the importance of the infection model as a reliable and valid model for studying different effects produced by highly diluted drugs. Considering the findings and in a broader perspective, this study contributes to considering these drugs as a possible way of dealing with "treatment" in general, presents the need to reexamine the biochemical model and develop a model for the effect of high dilutions in general, as well as for the treatment of parasitic infections.
