Insights
Hepatic steatosis (fatty liver) is common in children with human immunodeficiency virus (HIV) infection. This condition is non-specific and does not impact disease management, making ultrasonography a reliable screening tool.
Area of Science:
- Pediatrics
- Hepatology
- Infectious Diseases
Background:
- Human immunodeficiency virus (HIV) infection can affect multiple organ systems.
- Hepatic abnormalities are a known complication in HIV-infected individuals.
- The prevalence and impact of hepatic steatosis in pediatric HIV are not well-defined.
Purpose of the Study:
- To investigate the prevalence of morphologic hepatic abnormalities in HIV-infected children.
- To evaluate the utility of ultrasonography in detecting hepatic steatosis in this population.
- To determine the association between hepatic steatosis and HIV infection stage.
Main Methods:
- Cross-sectional study involving 30 HIV-infected children.
- Abdominal ultrasonography performed in 27 children to assess liver structure.
- Liver histology performed in 11 children for confirmation of steatosis.
- Patients categorized based on HIV infection stage (N, A, B, C).
Main Results:
- Abnormal liver structure, consistent with hepatic steatosis, was detected in 85% of children via ultrasonography.
- Histological examination confirmed steatosis in 91% of biopsied children, with 70% previously suspected by ultrasound.
- Steatosis was observed across all stages of HIV infection, with a higher prevalence in category C.
Conclusions:
- Hepatic steatosis is a common finding in HIV-infected children.
- Ultrasonography is a sensitive, accurate, and non-invasive method for screening hepatic steatosis.
- The presence of steatosis in this cohort appears non-specific and does not influence disease management.
Abstract:
Thirty HIV-infected children were cross-sectionally examined for morphologic hepatic abnormalities, using ultrasonography or histology. Abdominal ultrasonography was performed in 27 children. The liver structure was normal in four patients, one of whom had moderate symptoms of the HIV infection and three of them severe symptoms. Abnormal liver structure, compatible with hepatic steatosis, was found in 23 (85%) patients. Five of them were in an early stage of the HIV infection (category N or A), three patients were ranked in category B and 15 patients in category C. Histological examination of the liver was performed in 11 children and steatosis was documented in ten (91%). In seven (70%) of these ten children steatosis had been suspected by ultrasonography. In conclusion, steatosis is common in HIV-infected children. It is non-specific and has no impact on disease, diagnostic evaluation or management. Conclusion Ultrasonography is a sensitive, accurate, non-invasive screening tool. It is more reliable than liver function tests.
