Epidemiology of hepatitis C virus infections in children
Insights
Hepatitis C virus (HCV) infections in children were primarily iatrogenic, often linked to past hospitalizations even without invasive procedures. Familial exposure played a minor role in transmission.
Area of Science:
- Pediatric Hepatology
- Infectious Diseases Epidemiology
- Viral Hepatitis Research
Background:
- Analysis of epidemiological data for pediatric Hepatitis C virus (HCV) infections.
- Focus on children diagnosed and treated at a Hepatology Outpatient Clinic between 1996 and 1999.
Purpose of the Study:
- To investigate the epidemiological characteristics of HCV infections in children.
- To identify and analyze risk factors associated with HCV transmission in pediatric patients.
Main Methods:
- Study included 62 children with confirmed anti-HCV antibodies and/or HCV-RNA.
- Utilized ELISA for antibody detection and RT-PCR for viral RNA.
- Risk factor analysis based on comprehensive questionnaires.
Main Results:
- HCV infection was iatrogenic in 88.7% of cases.
- Hospitalization and associated procedures were primary risk factors, including blood transfusions (24.19%) and surgical procedures (22.58%).
- Even non-invasive hospital treatments posed a risk (19.35%), with familial exposure in only 4.84%.
Conclusions:
- The majority of pediatric HCV infections in this cohort were iatrogenic.
- Hospitalization, irrespective of invasiveness, is a significant risk factor for HCV.
- Familial transmission of HCV is of secondary importance compared to healthcare-associated exposures.
Background:
Epidemiological analysis of hepatitis C virus infections in children diagnosed and treated in the Hepatology Outpatient Clinic in Bytom between 1996 and 1999.
Material And Methods:
The study comprised 62 children with detected serum presence of anti-HCV antibodies (ELISA method) and/or HCV-RNA (RT-PCR method). Risk factors for the infection were thoroughly analysed on the base of questionnaires.
Results:
It was established that in 55 (88.7%) children high probability of infection existed in connection with past hospitalization and applied diagnostic and therapeutic procedures, such as: transfusion of blood and its preparations (24.19%), surgical procedures (22.58%), hospital treatment without invasive procedures and blood transfusions (19.35%). Familial exposure was a risk factor in 4.84% of cases, while in 6.45% of cases there were no burdens in the history.
Conclusions:
1. In the evaluated group of children HCV infection was iatrogenic in character in majority of cases. 2. Hospitalization, even without invasive procedures, may be an important risk factor for HCV infection. 3. Familial exposure seems to be of secondary importance in transmission of HCV infection.
