The leading cause of acute gastroenteritis (AGE) in children is rotavirus. In different countries, different rotavirus genotypes prevail and are associated with different severity of disease.
The purpose of our study was to identify the distribution of rotavirus genotypes in Kyiv, Ukraine, and to determine the correlation between the genotypes and course of disease.
Materials and methods. 978 children under 5 years of age were examined with АGE symptoms and not vaccinated against rotavirus. Determination of rotavirus antigen and genotype were performed using the immunoenzymatic assay and real-time RT-PCR.
We assessed the demographics, clinical manifestations of AGE, the Vesikari scale AGE severity.
Results. The G4P[8] genotype prevailed in Ukraine during 2014-2018. The G1P[8] was the second most common. G9P8 was the third, the fourth place was shared by G2P[4] and G3P[8]. Fever, as a manifestation, was more pronounced in G1P[8] and G3P[9].
The highest number of vomiting episodes per day occurred in the G1P[8] and G4P[8]-related cases.
Maximum of diarrhea episodes per day was observed in genotypes G1P[8], G3P[8], G4P[8] and G9P[8].
Mucus and blood in stool were found in genotypes G3P[8] (1/33.33 %), G4P[8] – blood (1/2.27 %).
The children with genotypes G1P[8] and G4P[8] had catarrhal symptoms.
More cases of moderate and severe dehydration, occurred in the G4P[8].
The Vesikari scale analysis showed that only G1P[8] led to mild cases(3.57 %). The most widespread genotypes, G1P[8] and G4P[8], led to a moderate illness in 14.29 % and 13.56 % cases, respectively, and to a severe illness in 82.14 % and 86.44 % cases, respectively.
Conclusions. G4P[8] was associated with the most severe disease due to more frequent and prolonged vomiting, febrile fever and bloody diarrhea. G1P[8] and G4P[8] were associated with catarrh.
