AIDS in two African children--one with fibrosarcoma of the liver
Insights
This study details acquired immune deficiency syndrome (AIDS) in two Black African children, highlighting its occurrence in those without transfusions or high-risk family members. It also notes the association between pediatric AIDS and cancer, with specific immune cell behavior observed.
Area of Science:
- Pediatric Immunology
- Infectious Diseases
- Oncology
Background:
- Acquired immune deficiency syndrome (AIDS) can present in children without typical risk factors.
- The co-occurrence of AIDS and malignancy in pediatric cases requires further investigation.
Observation:
- Two Black African girls developed AIDS: one presented with early-onset interstitial pneumonitis, and the other developed a liver fibrosarcoma.
- Maternal immune dysregulation was noted in the first patient's family.
- In the second patient, specific immune cells (OKT8 positive cells) exhibited T-killer precursor activity in vitro.
Findings:
- AIDS can affect Black African children, even without a history of transfusion or high-risk family contacts.
- A link between pediatric AIDS and cancer is demonstrated in these cases.
- In vitro analysis revealed cytotoxic suppressor lymphocytes acting as T-killer cell precursors.
Implications:
- These cases expand the understanding of AIDS presentation in diverse pediatric populations.
- The findings underscore the importance of considering AIDS in children with unexplained immune deficiencies and malignancies.
- Further research into immune cell dynamics in pediatric AIDS-associated cancers is warranted.
Abstract:
We report here on two black African girls who developed an acquired immune deficiency syndrome (AIDS). The first patient was a premature girl born to healthy parents. She suffered from interstitial pneumonitis during the first week of life and died of it at the age of 6 months. Her mother, although asymptomatic, had polyclonal hypergammaglobulinaemia, a reversed T-helper/T-suppressor ratio and a decreased lymphocyte response to mitogens. The second patient had the first symptoms at the age of 6 years, developed a primitive malignant fibrosarcoma of the liver at 8 years old and died 1 year later. AIDS can affect black African children who have not been transfused and whose family members are not considered as at a high risk for this disease. In children, AIDS and cancer can be associated. In the second patient, cytotoxic suppressor lymphocytes (OKT8 positive cells) were shown to behave in vitro as precursors of T-killer cells.
