[Prognostic factors in HIV seropositive children by materno-fetal transmission]
Insights
Pediatric HIV infection, transmitted from mother to child, often presents with enlarged lymph nodes and spleen. Immune deficiency and specific antibody profiles correlate with poor prognosis in children.
Area of Science:
- Pediatrics
- Immunology
- Infectious Diseases
Background:
- Maternal-fetal transmission is a significant route for pediatric HIV infection.
- Early identification of immunological markers is crucial for managing HIV in children.
Purpose of the Study:
- To investigate the immunological status and clinical manifestations of HIV-seropositive children.
- To establish the relationship between clinical symptoms, immunological markers, and prognosis in pediatric HIV cases.
Main Methods:
- Survey of 94 HIV-seropositive children diagnosed between 1983 and 1988.
- Assessment of immunological parameters including OKT4 lymphocyte counts and antigen-induced proliferative responses.
- Correlation of clinical symptoms (lymphadenopathy, hepatosplenomegaly, opportunistic infections) with immunological data and survival.
Main Results:
- 98% of cases exhibited lymphadenopathy and/or hepatosplenomegaly.
- Opportunistic infections, neurological issues, and lymphoid interstitial pneumonitis occurred in 28%, 16%, and 15% of cases, respectively.
- Low OKT4 counts (<500/mm3) and negative antigen responses were observed in 24% and 44% of cases, correlating with poorer survival.
Conclusions:
- Clinical symptoms like lymphadenopathy are highly prevalent in pediatric HIV.
- Immunological markers, particularly OKT4 cell counts and antigen response, are critical indicators of disease severity and prognosis.
- Evaluating immunological deficiency and infectious complications is essential for managing pediatric HIV.
Abstract:
Ninety-four cases with HIV seropositive children who were found in the Hospital Necker Enfants Malades in France from April 1983 till September 1988 due to materno-fetal transmission were surveyed for immunological studies as well as the relationship between clinical symptoms and the prognosis. Lymphoadenopathy and/or hepatosplenomegaly were found in 98% of the total cases. Opportunistic infections, severe neurological problems and LIP were found in 28%, 16% and 15%, respectively. At the first laboratory examination, cases showing under 500/mm3 of OKT4 lymphocytes and with negative antigen-induced proliferative responses were observed in 24% and 44% of the cases, respectively. Negative serological profiles of antibodies to P18 and P25 HIV antigens appeared to show low values of OKT4 lymphocytes and abnormal responses to antigens. The survival cases with these findings were minimum. These data indicate that it is very much worth, while to estimate the degree of immunological deficiency and infectious complications.
