International perspectives, progress, and future challenges of paediatric HIV infection

Area of Science:

• Pediatric Infectious Diseases
• Global Health
• Immunology

Background:

• Paediatric HIV infection presents a significant global health challenge, with high daily new infections.
• Mother-to-child transmission rates are low in developed countries (<2%) but high in developing countries (25-40%).
• Access to interventions remains critically low (5-10%) for women in resource-limited settings.

Purpose of the Study:

• To highlight the clinical and immunological features specific to paediatric HIV infection.
• To address the challenges in providing universal access to effective interventions for children globally.
• To emphasize the need for equitable access to antiretroviral therapy for children with HIV.

Main Methods:

• Review of clinical and immunological data specific to paediatric HIV.
• Analysis of global disparities in intervention access and transmission rates.
• Examination of the impact of antiretroviral therapy on childhood HIV progression.

Main Results:

• Untreated paediatric HIV progresses rapidly, with high mortality (>50% by 2 years) in resource-poor settings.
• Antiretroviral therapy can alter the natural history of paediatric HIV, similar to adults.
• Significant gaps exist in the accessibility of life-saving therapies for children worldwide.

Conclusions:

• Urgent global efforts are needed to bridge the gap in access to paediatric HIV interventions.
• Addressing the specific clinical and immunological needs of children is paramount.
• Achieving universal access to antiretroviral therapy is essential to reduce childhood HIV mortality and disease progression.
