Insights

Rotavirus gastroenteritis (RVGE) remains a significant cause of severe acute gastroenteritis (AGE) hospitalizations in Italian children under six. Despite rotavirus vaccination recommendations, RVGE continues to burden pediatric healthcare systems.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Public Health

Background:

  • Acute gastroenteritis (AGE) severity is etiologically linked, with Rotavirus (RV) causing most severe cases.
  • The World Health Organization recommended RV vaccination in 2009, but European adoption has been limited.
  • Rotavirus gastroenteritis (RVGE) represents a substantial global public health concern in pediatric populations.

Purpose of the Study:

  • To estimate the proportion and hospitalization rates of RVGE among children under six in Italy.
  • To analyze trends in RVGE hospitalizations between 2005 and 2012 using national data.
  • To assess the ongoing impact of Rotavirus on pediatric hospital admissions in Italy.

Main Methods:

  • Retrospective analysis of 334,982 hospital discharge forms from Italian hospitals (2005-2012).
  • Identification of 79,344 hospitalizations associated with Rotavirus (RVGE).
  • Calculation of hospitalization rates (HR) for RVGE, considering primary (PD) and secondary (SD) diagnoses.

Main Results:

  • An average hospitalization rate of 146/100,000 children for RVGE (PD) and 150/100,000 (SD).
  • RVGE hospitalizations in SD surpassed PD from 2008 onwards.
  • The highest proportion of RVGE hospitalizations (33.67%) occurred in children aged two years or younger.

Conclusions:

  • Rotavirus continues to be a significant cause of pediatric hospitalizations in Italy, despite available vaccination.
  • Analysis of national hospital discharge data, including secondary diagnoses, is crucial for understanding RVGE burden.
  • The findings underscore the need for continued surveillance and potential reinforcement of rotavirus vaccination strategies in Europe.
