Early detection of HIV infection among Kenyan infants using a reverse transcriptase activity assay

Area of Science:

• Pediatrics
• Infectious Diseases
• Virology

Background:

• Early diagnosis of Human Immunodeficiency Virus (HIV) in infants is crucial for timely treatment and improved outcomes.
• Existing diagnostic methods have limitations in early detection, particularly in resource-limited settings.

Purpose of the Study:

• To evaluate the utility of the Cavidi reverse transcriptase (RT) assay for early diagnosis of HIV infection in Kenyan infants.
• To compare the performance of the RT assay with DNA polymerase chain reaction (PCR) and antibody testing.

Main Methods:

• A cohort of 200 HIV-exposed Kenyan infants were enrolled.
• Infants were tested for HIV using DNA PCR and Cavidi RT assays at birth and at 6, 12, 24, and 48 weeks.
• HIV antibody testing was performed after 18 months of age.

Main Results:

• Eleven (5.5%) infants were diagnosed with HIV infection.
• In six infants, a positive RT assay result preceded a positive DNA PCR result.
• The RT assay demonstrated potential for earlier detection of HIV in infants.

Conclusions:

• The Cavidi RT assay shows promise for facilitating earlier HIV diagnosis in infants.
• Earlier diagnosis through RT assay can lead to prompt initiation of antiretroviral therapy.
• Further research is warranted to confirm the efficacy and cost-effectiveness of RT assay in diverse settings.
