Insights
Viral load monitoring in children with HIV on antiretroviral treatment showed a decrease in viral load and an increase in CD4/CD8 counts over three years. This method aids in assessing treatment response and predicting disease progression.
Area of Science:
- Pediatric Infectious Diseases
- Virology
- Immunology
Context:
- Human Immunodeficiency Virus (HIV) infection in children requires ongoing monitoring.
- Antiretroviral therapy (ART) is crucial for managing pediatric HIV.
- Viral load quantification is essential for therapeutic decision-making.
Purpose:
- To evaluate the effectiveness of viral load monitoring in pediatric HIV patients undergoing ART.
- To assess changes in viral load and lymphocyte subpopulations over time.
- To determine the utility of viral load as a prognostic and therapeutic assessment tool.
Summary:
- Fifty pediatric patients (1-12 years) with HIV were monitored for viral load every six months over three years using the AMPLICOR HIV-1 Monitor assay.
- Results indicated a decrease in viral load and an increase in CD4 and CD8 lymphocyte counts.
- No significant correlation was found between lymphocyte subpopulation counts and viral load levels.
Impact:
- Viral load measurement is confirmed as an effective method for quantifying plasma HIV-RNA.
- This quantification aids in defining patient status, predicting clinical outcomes, and evaluating ART efficacy.
- Regular viral load monitoring supports personalized treatment strategies in pediatric HIV management.
Background:
Viral load in pediatric patients with HIV infections can help to make therapeutic decisions to modify the evolution of the disease.
Aim:
To evaluate viral load in positive HIV children with antiretroviral treatment.
Material And Methods:
Viral load was measured every six months during three years in fifty pediatric patients chosen randomly in aged 1 to 12 years, using the Test Monitor HIV-1 AMPLICOR, version 1.5.
Results:
During the three years follow up, there was an increase in CD4 and CD8 lymphocyte count and decrease in the viral load. However, there was no significant relationship between lymphocyte subpopulation counts and viral loads.
Conclusions:
Viral load demonstrated to be an appropriate method to quantify plasma HIV-RNA. This tool can help to define the condition of a particular patient to predict clinical course of the disease and to assess the response to the treatment.
