CLINICAL AND LABORATORY FEATURES OF ACUTE VIRAL GASTROENTERITIS IN ADULTS, RESIDENTS OF NOVOSIBIRSK

The aim of this study was to determine the frequency and the clinical and laboratory features of acute viral gastroenteritis in adult patients the residents of Novosibirsk. Materials and methods: A total of 363 patients aged 16 to 82 years hospitalized with a diagnosis of “acute gastroenteritis” in the winter-spring season 2016 and with no evidence of immunosuppression were examined. In addition to generally accepted diagnostic techniques faeces were investigated using polymerase chain reaction for the detection and differentiation group A and C rotaviruses (HRVA and HRVC), II norovirus genogroup II (HNoV GII) and astroviruses (HAstV) with applying the original set of specific primers. Results: Viral etiology has been set at 19,6% of patients with acute gastroenteritis. Noroviruses were predominant (10,2%), the proportion of rotavirus was 7,7%, astroviruses - 1,7%. The proportion of viral gastroenteritis was higher in the winter months and decreased in spring months. The moderate form of the disease dominated (99.4%). No significant differences in clinical symptoms, blood count and coprogram parameters were revealed in patients with different etiology of viral gastroenteritis, except the higher frequency of lymphocytosis in norovirus infection (p < 0,05). Conclusion: Set frequency of viral gastroenteritis in adults, no significant differences in the clinical picture of viral gastroenteritis of various etiologies determine the necessity of elaboration and introduction into clinical practice of universal test systems for the detection of common viral pathogens.
