Pediatric Enhanced Surveillance Study

Completed

• Conditions: Acquired Immune Deficiency Syndrome (AIDS); Human Immunodeficiency Virus (HIV)

• Registration Number: NCT02043769
• Lead Sponsor: Columbia University

Brief Summary

The Pediatric Enhanced Surveillance Study is a three part study of HIV-infected infants and children in South Africa to examine, clinical, immunologic, virologic, metabolic, psychosocial and behavioral outcomes. This study has two parts: (1) comprehensive de-identified records review of all HIV-infected children enrolled in at the pediatric Wellness and ART clinics at the five study sites; and (2) a prospective cohort surveillance study with active consented enrollment with 12-24 months of follow-up. As part of the prospective cohort, the study will aim to collect outcomes on children lost to follow-up, including causes of death through review of death certificates in the clinical chart and through verbal autopsy reports. The study will provide insights into overall outcomes for the larger pediatric patient populations in the province and South Africa. This work is designed in collaboration with the provincial health authorities of the Eastern Cape Department of Health (EC), The International Center for acquired immune deficiency syndrome (AIDS) Care and Treatment Programs (ICAP) South Africa and Center of Disease Control (CDC)-South Africa in support of the South African National ART Program for Children and aims to collect and analyze accurate, relevant and useful information that will be available on children seen at facilities. For the prospective cohort study, we will aim to enroll 400 children newly initiated on ART at 5 health facilities in the Eastern Cape of South Africa who will be actively followed for up to 24 months.

Detailed Description

South Africa is one of the countries hardest hit by the HIV/AIDS epidemic. There are more than 5 million people living with HIV in South Africa, including 280,000 children under the age of 15. Most HIV positive children acquire infection through mother-to-child transmission; in South Africa 29.3% of pregnant women attending antenatal services are HIV-infected. Furthermore, it is estimated that HIV is the cause of 35% of all deaths in children under five in South Africa. The South African government began a national rollout of HIV treatment for adults and children in 2003. As of 2007, an estimated 32,060 children under the age of 15 were receiving antiretroviral therapy (roughly 30% of those in need). There is an urgent need to obtain more comprehensive, in-depth, profiles of children enrolled in HIV care with a focus on documenting outcomes, particularly timing and causes of death, reasons for loss to follow-up, timing and frequency of treatment failure, adverse events, metabolic complications and psychosocial aspects of HIV disease.

Primary Outcome Measures

Name	Time	Method
Proportion of children alive and in care at 12 and 24 months after treatment initiation	Up to 24 months	We will measure the proportion of children alive and in care at 12 and 24 months after treatment initiation amount prospective cohort participants through routine clinical and study visits.

Secondary Outcome Measures

Name	Time	Method
Proportion of the children enrolled in human immunodeficiency virus (HIV) care and treatment services	Up to 24 months	We will describe the proportion of the children enrolled in HIV care and treatment services at the study facilities who start treatment and are retained in care for 6, 12, 24, 36 and 48 months by reviewing clinical records at each facility.
Proportion of children with documented deaths	Up to 24 months	We will describe proportion of children with documented deaths and causes of deaths and time to death (from enrollment) by reviewing clinical records of participants.
Proportion of children lost to follow-up	Up to 24 months	We will describe the proportion of children lost to follow-up after enrollment in care and in those starting treatment by reviewing clinical records of study participants.
Proportion of children on antiretroviral therapy (ART) with diminished CD4 (cluster of differentiation 4) counts	Up to 24 months	We will measure the proportion of children, aged 2 to 5 years, on ART with CD4% \<10% at 12, 24\* months after treatment initiation and children older than 5 years on ART with CD4 count of \< 100 at 12, 24 months after treatment initiation. These outcomes will be measured in participants of the prospective cohort who will give additional blood samples during routine clinical care.
Proportion of children on antiretroviral therapy (ART) progressing to WHO Stage 4 disease	Up to 24 months	We will measure the proportion of children on ART progressing to WHO Stage 4 disease at 12 and 24 months after treatment initiation in the prospective cohort.
Proportion of children who are virologically suppressed	Up to 24 months	We will measure the proportion of children who are virologically suppressed (\< 400 copies/mL, per South African National Guidelines) at 12 and 24\* months after treatment initiation in the prospective cohort through routine clinical and study visits.
