Pediatric HIV-1 disease in a Kampala Hospital
Insights
Pediatric HIV-1 infection, primarily perinatal, significantly increased mortality in Ugandan children under two. WHO AIDS symptoms were unreliable indicators in this vulnerable population.
Area of Science:
- Pediatric infectious diseases
- Epidemiology of Human Immunodeficiency Virus (HIV)
- Global child health in resource-limited settings
Background:
- HIV-1 infection posed a significant threat to pediatric populations in developing countries during the late 20th century.
- Understanding the transmission, clinical presentation, and outcomes of pediatric HIV-1 is crucial for effective public health interventions.
- Limited data existed on the specific impact of HIV-1 on children in Uganda during the initial years of the epidemic.
Purpose of the Study:
- To retrospectively analyze the characteristics and outcomes of pediatric HIV-1 infection in Ugandan children.
- To evaluate the effectiveness of the World Health Organization (WHO) clinical case definition for pediatric Acquired Immunodeficiency Syndrome (AIDS).
- To compare the prevalence of common childhood illnesses, such as malaria and measles, in HIV-1 positive versus HIV-1 negative children.
Main Methods:
- Retrospective analysis of pediatric patient data screened for HIV-1 infection.
- Study conducted between 1985 and 1989 at a major mission hospital in Kampala, Uganda.
- Inclusion criteria focused on symptomatic HIV-1 infection and comparison groups.
Main Results:
- Symptomatic HIV-1 infection was predominantly acquired perinatally, with 87% diagnosed in children under two years old.
- The mortality rate for pediatric inpatients with symptomatic HIV-1 infection was 40%, compared to 12% for all pediatric inpatients.
- WHO clinical case definition symptoms for pediatric AIDS showed low sensitivity, specificity, and positive predictive value; no difference in malaria or measles prevalence was observed between HIV-1 positive and negative children.
Conclusions:
- Perinatal HIV-1 transmission was a major driver of pediatric symptomatic infection and mortality in Uganda during this period.
- The WHO clinical case definition for pediatric AIDS was not a reliable diagnostic tool in this setting.
- Co-infections like malaria and measles did not differ in prevalence, suggesting HIV-1 was the primary driver of severe outcomes.
Abstract:
Data of pediatric patients screened for HIV-1 infection between 1985 and 1989 were studied retrospectively in one of the major mission hospitals of Kampala (Uganda). Symptomatic HIV-1 infection was mainly acquired perinatally and was diagnosed in 87 per cent in children under 2 years of age. The mortality rate was 40 per cent in pediatric in-patients with symptomatic HIV-1 infection as compared to 12 per cent in overall pediatric inpatients. Symptoms included in the WHO clinical case definition for pediatric AIDS were mainly insensitive, unspecific and demonstrated a low positive predictive value. There was no difference in the prevalence of malaria and measles between HIV-1 positive and HIV-1 negative children.
