[State of cellular and humoral immunity in children infected with human immunodeficiency virus]
Insights
Human immunodeficiency virus (HIV) infection in children causes severe immune system depression early on. This immune deficiency, marked by low T helper lymphocytes and high immune complexes, increases opportunistic infection risk.
Area of Science:
- Immunology
- Pediatrics
- Infectious Diseases
Background:
- Human immunodeficiency virus (HIV) infection impacts children globally.
- Understanding immune system alterations in pediatric HIV is crucial for early intervention.
- Previous research highlights immune dysfunction in HIV, but early-stage pediatric data requires further investigation.
Purpose of the Study:
- To investigate cellular and humoral immunity in children with HIV.
- To compare immunological parameters between HIV-infected children and healthy controls.
- To identify early immunological markers of disease progression in pediatric HIV.
Main Methods:
- Examined cellular and humoral immunity in 32 children with HIV.
- Included comparative analysis with 6 healthy children and 11 children with other diseases.
- Assessed T lymphocyte subsets (T helper, T suppressor) and circulating immune complexes.
Main Results:
- Revealed a significant decrease in absolute T helper lymphocyte count.
- Observed a reduced T helper/T suppressor cell ratio.
- Detected elevated levels of circulating immune complexes.
- Demonstrated severe immunodepression in early stages of HIV infection in children.
Conclusions:
- Early-stage pediatric HIV infection is characterized by profound immunodepression.
- Alterations in immunological parameters, including T cell counts and immune complexes, are significant.
- These immunological changes likely contribute to the development of opportunistic infections in children with HIV.
Abstract:
Cellular and humoral immunity was examined in 32 children infected with human immunodeficiency virus, living in the Kalmyk ASSR. For comparison purposes, examinations were also made of 6 healthy children and 11 children afflicted with different diseases, living in the same republic. A dramatic lowering of the absolute content of T helper lymphocytes, an appreciable decrease of the T helper/T suppressor ratio associated with the high level of circulating immune complexes were revealed. In children infected with human immunodeficiency virus, grave immunodepression occurred at the early stages of the pathological process. The authors describe the totality of alterations in the immunological parameters, which may give rise to the generalized forms of opportunistic diseases in children infected with human immunodeficiency virus.
