[Current etiological structure of acute viral hepatitis in children].

The etiological structure of viral hepatitides (VH) was defined in 345 children admitted to the clinic during one year with a diagnosis of acute viral hepatitis. It was established on the basis of clinico-laboratory studies and identification of serological markers of viral hepatitides A, B and delta. It has been demonstrated that in the structure of viral hepatitides in children living in Moscow, VHA accounts for 83.1%, acute VHB for 11.1%, HBV and HDV coinfection for 2.6%, and VH non A non B for 1.7%. In children of the first year of life, acute hepatitis was etiologically related to HBV-infection or to HBV and HDV coinfection. In a negligible part of the patients, VHA was diagnosed in the presence of chronic HBV-infection (1.2%) or exacerbation of chronic hepatitis B (0.3%). These data should be taken into consideration in planning and carrying out diagnostic, treatment and prophylactic measures aimed at solving VH problem in childhood.
