Etiological characteristics of infectious diarrhea in children in Cheboksary in 2017

Keywords: diarrhea, children, incidence, age, acute enteric infections

Despite introduction of modern clinical recommendations for diagnosing and treating diseases of the gastrointestinal tract into medical practice, as well as strict monitoring of compliance with sanitary rules and norms of prevention at preschool and school institutions, the incidence of acute enteric infections (AEI) among children remains high. According to the Federal Service on Customers' Rights Protection and Human Well-being Surveillance of the Chuvash Republic, the incidence rate of AEI of diagnosed etiology per 100 thousand children under the age of 17 years in 2015 was 768,2 cases, and in 2017 it was already 811,2, that of unknown etiology – 1741,0 and 2025,3 cases, respectively. The purpose of this study is to examine the contribution of various pathogens into the overall structure of sporadic AEI incidence among children of Cheboksary, as well as to assess differences in the prevalence of pathogens depending on the age of the sick and the season. The study included 2272 children with diarrhea syndrome who were admitted for treatment to the infectious in-patient department of Cheboksary Municipal Children's Hospital № 2 in 2015–2017. The diagnosis was confirmed in 1181 patients, which made 52%. These patients were divided into four groups: the 1st group included 331 children under the age of 1 year, the 2nd – 536 children aged from 1 to 3 years, the 3rd – 234 children aged from 3 up to 7 years, the 4th – 80 children of school age. The standard examination algorithm included bacteriological studies of feces for pathogenic and opportunistic microorganisms, campylobacteriae, enzyme-linked immunoassay of the feces for detecting Rota-, Nora-, Astrovirus antigens, enteroviruses, polymerase chain reaction for detecting RNA viruses in feces, serological tests for the detection of specific antibodies to pathogens in the serum and scatoscopy. In all age groups, diarrhea of viral etiology prevailed. Among verified bacterial pathogens, Salmanellae, Escherichiae and opportunistic microorganisms were found more often than others. It was established that the incidence of viral diarrhea was higher in winter-spring period, and bacterial – in summer period.
