Insights
Twelve HIV-positive children born to HIV-seropositive mothers were studied. Four (33.3%) developed the disease, with transmission via blood transfusion, highlighting risks in pediatric HIV.
Area of Science:
- Pediatric Infectious Diseases
- Virology
- Immunology
Context:
- Mother-to-child transmission of HIV remains a global health concern.
- Limited data exists on the long-term outcomes of HIV-seropositive children.
- Understanding transmission routes is crucial for prevention strategies.
Purpose:
- To investigate the clinical outcomes and transmission routes in a cohort of HIV-seropositive children.
- To evaluate the effectiveness of diagnostic testing in early identification of pediatric HIV.
- To monitor disease progression in vertically infected infants.
Summary:
- Twelve HIV-seropositive children born to HIV-seropositive mothers were monitored.
- Four children (33.3%) developed symptomatic HIV disease.
- Blood transfusion was identified as the transmission route in these cases.
- Diagnostic confirmation involved Polymerase Chain Reaction (PCR), ELISA, and Western Blot at multiple time points (3, 6, 9, 18, and 36 months).
Impact:
- This study highlights a significant disease progression rate in a small cohort of vertically infected children.
- Identifies blood transfusion as a potential, albeit uncommon, route of HIV transmission in infants.
- Emphasizes the importance of rigorous diagnostic follow-up for early HIV detection and management in children.
Abstract:
Up to this moment, 25 children have been born from mothers seropositive to HIV. Of these, only 12 who are seropositive have been studied. Four of these children had developed the disease (33.3%), and the route of transmission was a blood transfusion. From the moment they were born, these children had been followed up monthly at the out-patient service and the polymerase chain reaction test, as well as ELISA and western blot is performed at 3, 6, and 9 months of age. Also, the same test are performed at 18 and 36 months of age for diagnostic confirmation in order to know whether they are virus carriers.
