Insights
Hepatitis C virus (HCV) infection incidence in hospitalized children was 3.7%. Most infections were linked to prior hospitalizations and invasive procedures, suggesting iatrogenic transmission.
Area of Science:
- Pediatric Gastroenterology
- Infectious Diseases
- Hepatology
Background:
- Hepatitis C virus (HCV) poses a significant public health concern.
- Understanding HCV transmission routes in pediatric populations is crucial for prevention.
Purpose of the Study:
- To estimate the incidence of HCV infection among hospitalized children.
- To identify risk factors associated with HCV infection in this demographic.
Main Methods:
- Retrospective analysis of 1263 pediatric patients' data from July 1995 to March 1998.
- HCV antibody testing using enzyme immunoassay, confirmed by Lia Tek HCV or PCR HCV RNA.
- Review of patient history for hospitalizations, surgeries, blood transfusions, and invasive procedures.
Main Results:
- HCV infection was diagnosed in 3.7% (47 out of 1263) of the children studied.
- 96.2% of seropositive children had a history of hospitalization.
- 73.2% of infected children underwent procedures disrupting tissue continuity during previous hospitalizations, suggesting parenteral transmission.
Conclusions:
- Routine serological screening for HCV infection is recommended for frequently hospitalized children.
- Iatrogenic transmission is the likely source of HCV infection in the majority of seropositive pediatric patients.
Aim:
The aim of the study was the estimation of the incidence of HCV infection and the analysis of risk factors for the infection in hospitalized children.
Material And Methods:
Retrospective analysis of the data of 1263 patients treated in hospital wards of Chair and Department of Gastroenterology and Paediatric Diseases from July 1995 to March 1998; all the patients had hepatitis C virus antibodies determined. Hepatitis C virus antibodies were assessed with the use of enzyme immunoassay. All the positive results were confirmed by means of Lia Tek HCV or PCR HCV RNA method. History data regarding frequency of previous hospitalizations, operations, blood transfusions and invasive diagnostic procedures patients had undergone were included in analysis.
Results:
HCV infection was diagnosed in 47 children which accounted for 3.7% of the group enrolled in the study. The majority, that is 96.2% of seropositive children had the history of hospitalization, while 73.2% of them underwent intervention procedures disrupting tissue continuity during previous hospitalizations. Physical examination analysis indicates that all the patients with antibodies against HCV could have acquired the infection through parenteral transmission. The data indicating another route of transmission were not obtained (e.g. familial transmission).
Conclusions:
1. Serological tests for HCV infection should be performed on routine basis in frequently hospitalized children. 2. HCV infection resulting from iatrogenic transmission can be suspected in the majority of seropositive children.
