From the Guidelines
For a 15-month-old child weighing 21 kg with acute HIV infection, the recommended antiretroviral therapy regimen should be initiated as soon as possible, considering the child's age and weight, and ideally consisting of a combination of antiretroviral agents, although the provided evidence does not specify the exact regimen for this age and weight group. Given the child's age, the guidelines from 1 suggest that antiretroviral therapy should be initiated in all HIV-infected infants as soon as a confirmed diagnosis is established, regardless of clinical or immunologic status or viral load, but these guidelines are from 1998 and do not provide specific recommendations for a 15-month-old child weighing 21 kg. However, considering the principles of treating HIV infection, the goal is to suppress viral replication, preserve immune function, reduce inflammation, and prevent disease progression. Key considerations in choosing an antiretroviral regimen include the potential for adverse effects, the likelihood of adherence, and the resistance profile. In clinical practice, for a child of this age and weight, a regimen consisting of two nucleoside reverse transcriptase inhibitors (NRTIs) plus an integrase strand transfer inhibitor (INSTI) could be considered, but the exact dosing would need to be determined based on the most current and relevant guidelines, which are not provided here. Regular monitoring with viral load testing, CD4 count monitoring, assessment of growth and development, and screening for potential drug side effects would be essential, along with adherence support for the caregiver. It's crucial to consult the most recent guidelines and expert opinion for the specific treatment of a 15-month-old child with acute HIV infection, as the provided evidence from 1 does not directly address this scenario.

From the Research
Antiretroviral Therapy (ART) Regimen for a 15-month-old Child
- The recommended ART regimen for a 15-month-old child weighing 21 kg with acute Human Immunodeficiency Virus (HIV) infection is not explicitly stated in the provided studies.
- However, the studies suggest that co-trimoxazole prophylaxis is an effective intervention in preventing opportunistic infections in HIV-infected children 2, 3, 4, 5.
- A study published in 2006 found that co-trimoxazole prophylaxis reduced mortality by 33% in HIV-infected children in Zambia 2.
- Another study published in 2007 discussed the potential operational benefits and favorable recommendations by WHO, UNAIDS, and UNICEF for the use of co-trimoxazole prophylaxis in HIV-exposed and HIV-infected children 3.
- A study published in 2014 found that continuing co-trimoxazole prophylaxis after 96 weeks of ART was beneficial in reducing hospitalizations for malaria and infections not related to malaria in HIV-infected children in Africa 5.
- A study published in 2006 investigated the oral trimethoprim-sulphamethoxazole levels in stable HIV-infected children and found that therapeutic concentrations of trimethoprim for treatment of Pneumocystis jiroveci pneumonia can be attained with an oral loading dose of 20 mg/kg and sustained with a second dose at 6 hours of either 5 mg or 10 mg/kg 6.
Co-trimoxazole Prophylaxis
- Co-trimoxazole prophylaxis is recommended for HIV-infected children to prevent opportunistic infections such as Pneumocystis jiroveci pneumonia (PCP) 2, 3, 4, 5.
- The dosage of co-trimoxazole prophylaxis is typically based on the child's age rather than body weight 4.
- A study published in 2015 found that the majority of children who were initiated with co-trimoxazole prophylaxis did not experience significant opportunistic infections, and the drug was well tolerated 4.
ART Regimen
- The provided studies do not specifically address the recommended ART regimen for a 15-month-old child weighing 21 kg with acute HIV infection.
- However, the studies suggest that co-trimoxazole prophylaxis is an important component of the management of HIV-infected children, particularly in resource-limited settings 2, 3, 4, 5.
