Insights
Chile
Area of Science:
- Pediatrics
- Infectious Diseases
- Public Health
Background:
- Human Immunodeficiency Virus (HIV) emerged as a significant global health challenge.
- The Pediatric HIV/AIDS Committee of the Chilean Pediatric Society has played a crucial role since the first pediatric HIV case in Chile.
- Promoting screening and referral for HIV-exposed and infected children is vital.
Purpose of the Study:
- To disseminate the experience of the Chilean Pediatric HIV/AIDS Committee.
- To review the history and outcomes of the Pediatric HIV/AIDS Care Program in Chile.
- To analyze data on pediatric HIV cases and the impact of interventions.
Main Methods:
- Analysis of national and international literature.
- Review of presentations from Committee Congresses/Workshops.
- Examination of patient data from 1987-2014 (Cohort 1 and Cohort 2).
Main Results:
- The Preventive Vertical Transmission Program (PPTV) for HIV has reduced vertical transmission rates from over 35% to under 2%.
- Antiretroviral therapy (ART) has led to significant clinical, immunological, and virological improvements.
- Prolonged survival has been achieved in children with HIV.
Conclusions:
- Chile is nearing the goal of eradicating vertical HIV transmission.
- The PPTV and ART have been highly effective in managing pediatric HIV.
- The Chilean Pediatric HIV/AIDS Committee's experience offers valuable insights into HIV care.
Abstract:
HIV has been the major infection of the late 20th century. This review has the objective of dissemina ting the experience of the Pediatric HIV/AIDS Committee of the Chilean Pediatric Society since the detection of the first HIV-infected child in Chile and promoting the screening and referral of new- borns/children exposed to HIV and those infected with HIV. Updated data from the national and fo reign literature, presentations in Congresses/Workshops held by the Pediatric HIV/AIDS Committee, and experiences of its members are analyzed. It is presented the history of the Pediatric HIV/AIDS Care Program in screening, diagnosis, treatment, and follow-up since its inception in 1990. The data on patients detected from 1987 to 2008 by the Committee (Cohort 1) and those obtained by e-mail from patients detected from 1987 to 2014 (Cohort 2) are presented. The analysis of these cohorts led to the conclusion that with the application of the Preventive Vertical Transmission Program (PPTV) for HIV, the vertical transmission of this virus has decreased from >35% prior to 1995 to <2% at present, and that clinical, immunological and virological improvement with prolonged survival has been obtained with the use of ART. Finally, we discuss the achievements obtained by comparing the results with those of the current literature, showing that Chile is on the brink of achieving the goal of eradicating the vertical transmission of HIV.
