ABSTRACT

Introduction: Diarrheal diseases are a relevant cause of infant morbidity and mortality and constitute a substantial public health problem in the pediatric population of developing countries. This clinical picture is among the first five causes of death in Latin America and represents a high percentage of pediatric consultations in the health services of that region. Acute diarrhea is a frequent pathology in childhood, however, a proportion of cases continues over time producing prolonged and persistent diarrhea. These episodes have been related to growth disorders, nutritional deficiencies and increased susceptibility to infections. Objective: To detect the etiological agents of acute, prolonged, and persistent diarrhea in the pediatric population that is attended at the «Doctor Debilio Blanco Villegas» Hospital in Tandil, Argentina, during 2016-2017. Material and methods: The study design was observational, descriptive, prospective and cross-sectional. The enteric pathogens investigated were bacteria, viruses and protozoa, using a combination of standard microbiological diagnostic techniques. Shiga toxins were detected by molecular methods. Results: The frequency of infectious diarrhea was 40% (77/190) and the etiological agents were EPEC, Shigella spp, Salmonella enterica, STEC (stx2), Rotavirus, Giardia intestinalis, Cryptosporidium spp and Blastocystis spp. The frequency of prolonged and persistent diarrhea reached 23% and the pathogens found were EPEC, Shigella spp, S. enterica, Cryptosporidium spp and Blastocystis spp. Conclusions: the presence of enteric pathogens was observed in four out of ten children with diarrhea and the etiological agents EPEC and Shigella spp they accounted for 70% of the cases. The information presented in this study serves as a baseline for establishing the frequencies of acute, prolonged and persistent diarrhea; and provides local and regional evidence for future research.
