Metanálisis sobre resultados de estudios coproparasitarios en el contexto latinoamericano

ABSTRACT A meta-analysis of published data on endoparasites in Latin American countries was carried out in the present study. They continue to be a public health problem and are therefore used to indicate the hygienic-sanitary and socioeconomic level of the populations. Parasitosis mainly affects children, triggering structural and cognitive alterations. The research is a retrospective documentary study, where primary and secondary sources were consulted, and 120 scientific documents were obtained, 101 of which were selected because they met the inclusion criteria, and 68 were selected for the elaboration of results extracted from documents registered in different databases such as Scopus, Pubmed, Elsevier, etc. The most frequent species reported were recorded from the analysis of the coproparasitic studies obtained, data on diagnostic techniques, the parasitic prevalence of protozoa, and helminths. Finally, the results were related to the altitude and temperature of the study areas. It was concluded that the diagnosis of coproparasites is generally made by direct examination because it is simple, specific, and economical; the best-known concentration techniques are Kato-Katz, Ritchie, and Willis, but they are little used. The highest parasite prevalence reached 98.39% and was recorded in a rural region of Riobamba canton, Chimborazo, Ecuador. Most studies show a higher prevalence of protozoa than helminths, with Blastocystis spp. Being the most frequent parasite among the pathogenic protozoa, Giardia duodenalis and Entamoeba histolytica stand out; among the most reported non-pathogens are Entamoeba coli and Endolimax nana. The most prevalent helminth in rural areas of low altitude was Ascaris lumbricoides, while in urban areas, it was Trichuris trichiura. In high altitude Andean areas, Hymenolepis nana is predominant. Populations in rural and marginal urban areas are the most affected by enteroparasites, prevailing in low altitude and higher temperature localities such as the coast and the jungle. In higher altitude areas, geohelminth prevalences are negligible due to climatic conditions. It is recommended to continue the research with data unique to Ecuador because there are no bibliometric analyses on intestinal parasites in our country.
