Insights
Chile
Area of Science:
- Pediatric Infectious Diseases
- Epidemiology
- Public Health
Background:
- The study examines the cohort of children with HIV/AIDS in Chile from 1987 to 2014.
- It assesses the impact of the Protocol for Prevention of Vertical Transmission (PPVT) on HIV infection rates.
Purpose of the Study:
- To analyze the trends in pediatric HIV/AIDS detection and outcomes in Chile.
- To evaluate the effectiveness of the PPVT in reducing vertical HIV transmission.
Main Methods:
- Retrospective analysis of a pediatric HIV/AIDS cohort data from 1987 to 2014.
- Evaluation of the impact of antiretroviral therapy (ARVT) and PPVT on clinical and immunological parameters.
Main Results:
- Improved early detection of HIV in children, though many are still diagnosed via symptoms.
- Antiretroviral therapy (ARVT) significantly improved child health, survival, and quality of life, reducing opportunistic infections and mortality.
- The PPVT drastically reduced vertical HIV transmission from over 35% to under 2%, enabling uninfected second-generation births.
Conclusions:
- While PPVT has been highly effective, ongoing detection of HIV-infected children indicates persistent gaps in the healthcare system.
- Continued efforts are needed to strengthen HIV prevention and early detection strategies in pediatric populations.
Abstract:
The present document describes the Cohort of HIV/AIDS children detected in Chile from 1987 to August 2014 and the effectiveness of the Protocol for Prevention of Vertical Transmission (PPVT) of HIV infection. Of the 375 HIV infected children enrolled since 1987 to August 2014, 245 of them are still in pediatric control. From the analysis of the Cohort is inferred that: a) it has observed an improvement in the detection of the HIV infected child, in number and precocious time; b) the majority of these children continue to be detected by clinic symptoms and signs (mainly unspecific and infectious manifestations); c) the ARVT use has meant a clinic and immunologic improvement with diminution of the infections, principally opportunistic infections, with a better life quality, a prolongation of survival and a diminution of lethality; d) as more survival has been produced, cancer has begun to be detected, a very infrequent complication observed in them before the ARVT use. The PPVT started in 1995, and was reinforced in 2005 with the "Joint Norm of HIV and Syphilis Vertical Transmission Prevention" (MINSAL), both have meant a diminution of the HIV vertical transmission from > 35% (before 1995) to < 2% nowadays in the mother-child binomial; also have permitted a second generation of HIV exposed children born without infection. In spite this PPVT, still HIV infected child continue to be detected which imply failures in some points of the health system.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
