CLINICAL-EPIDEMIOLOGICAL FEATURES AND OUTCOME OF GENERALIZED FORMS OF MENINGOCOCCAL INFECTION IN CHILDREN

Abstract

The objective of the research was to study clinical and epidemiological features and outcomes of generalized forms of meningococcal infection in children from Krasnoyarsk and Krasnoyarsk Territory during the period from 2012 to 2016. Materials and methods. A retrospective analysis of 57 medical records of hospital patients with generalized forms of meningococcal infection was carried out in the infectious and resuscitative departments of the Krasnoyarsk Clinical Hospital No. 1 from 2012 to 2016, including 12 protocols of pathologoanatomical studies of the deceased patients and 45 medical cards of ambulatory patients – convalescents of the disease from 2012 to 2016. Results. The epidemic situation for meningococcal infection in Krasnoyarsk Territory from 2012 to 2016 is characterized by signs of inter-epidemic period. Children of the first 3 years of life are in the group of high risk for the development of GFMI, which accounts for 74% of the total number of cases of children aged 14. There are signs of meningococcal infection « aging » – in the age structure the number of children in the first year of life decreased, while the proportion of children aged 4 – 7 and 7 – 14 increased compared to previous decades. There is a tendency to a decrease in the proportion of the combined forms with an increase in the frequency of « pure » meningococcemia. In recent years there has been an « atypical » course of generalized forms of the disease, when classical hemorrhagic necrotic rashes appear only on the 3rd – 4th day of the disease. In convalescents who underwent a combined form of MI and « pure » meningitis severe residual effects leading patients to disability are possible to develop. Conclusion. The use of polyvalent conjugated vaccines in potential risk groups will allow us to reduce the morbidity and mortality from generalized forms of meningococcal infection, including younger children.
