Plain English Summary

Background and study aims
Many children with perinatal HIV are now surviving to adolescence because of increased access to antiretroviral therapy (ART). Despite effective ART, non-AIDS-defining illnesses including cardiac (heart) disease have been described in both adults and children. Many children with perinatal HIV in Sub-Saharan Africa (SSA) start ART much later than children with HIV in high-income countries (aged 7.9 years vs 0.9 years, respectively) and are likely to have more HIV-related cardiac damage. Researchers have previously reported a high prevalence of cardiac abnormalities based on echocardiography examination and commonly left heart abnormalities. The causes of cardiac disease in HIV remain poorly understood but chronic inflammation due to HIV and/or other co-infections that may occur is believed to be one of the main drivers. Cardiac magnetic resonance (CMR) is unique in identifying tissue characteristics including scarring and inflammation, helping to understand underlying disease processes. In addition it enables more accurate structural and functional assessment of the heart. The aims of this study are to assess the structure, function and tissue characteristics of the heart using CMR. Biomarkers of scarring and inflammation will also be measured to help understand the causes of cardiac disease in children with perinatal HIV.

Who can participate?
Adolescents aged between 10 to 19 years with perinatal HIV and those without HIV

What does the study involve?
Two groups of adolescents will be enrolled (with and without HIV). Clinical and other medical history will be collected using questionnaires. Assessments including height, weight, blood pressure and blood tests will be performed (HIV group: CD4 count, HIV viral load, full blood count and serum creatinine). For adolescents without HIV, only full blood count and serum creatinine tests will be performed. All participants will be examined using CMR and blood samples will be collected to test for biomarkers of inflammation and scarring.

What are the possible benefits and risks of participating?
Adolescents without HIV will benefit from screening for HIV and those who test HIV-positive will be referred to the HIV clinic for onward care. All test results will be made available to the participant’s physician to assist with care. Participants diagnosed with cardiac disease will be referred for cardiac services for further management. All participants will benefit by finding out how well their heart is working.
Risks to participants may include CMR contrast negative reactions. During CMR, participants will receive a contrast agent as part of the examination. The contrast may cause a mild headache, rash and very rarely a more severe allergic reaction. These severe reactions generally respond very well to standard emergency drug treatment. Participants may experience anxiety while awaiting the results of tests done. To reduce the anxiety, they will be assured of referral for continued care should the results be abnormal.

Where is the study run from?
Sally Mugabe Central Hospital (Zimbabwe)

Study acronymCORD
Study hypothesisThe main aims of this study are to assess myocardial disease using cardiac magnetic resonance imaging in adolescents with perinatal HIV and established on antiretroviral therapy (ART). Secondly, this study seeks to understand the role of inflammation and fibrosis in the pathophysiological process of HIV-associated cardiac dysfunction.

ConditionMyocardial disease in adolescents with perinatal HIV and receiving antiretroviral therapy (ART)
InterventionElectronic clinic data and patient-held records will be used to confirm clinical and ART history. A clinical questionnaire will be administered by the research nurse to record demographic, prior medical history (previous illnesses and treatment history other than ART) and other exposures to risk factors for cardiac disease (tobacco smoking and drug history). Participants will undergo clinical assessment including anthropometry, heart rate, blood pressure, respiratory rate, pulse oximetry and New York Heart Association (NYHA) functional score. Participants without HIV will be screened for HIV prior to enrolment using an oral mucosal test.

CD4 count will be measured using a point of care Alere PIMA analyser. Blood samples will be collected from all participants for HIV viral load, Full blood count, serum creatinine, cytomegalovirus DNA and biomarkers tests. Biomarkers for myocardial stress and injury, fibrosis and systemic inflammation will be measured using bead multi-analyte assays (Luminex).

A standardized 12-lead electrocardiogram (ECG) and transthoracic echocardiography will be performed. Criteria for cardiac measurements will be based on the American Society of Echocardiography (ASE)/European Association of Cardiovascular Imaging (EACVI). A cardiac magnetic resonance imaging scan will be performed using a standard protocol including cine imaging using steady-state free precession with breath-hold for quantification of cardiac volumes and mass. Gadolinium-based contrast will be injected into the participants to assess late gadolinium-enhancement (LGE) for the presence, location and extent of focal fibrosis and parametric mapping (T1 and T2) for diffuse disease. All measured parameters will be adjusted to body surface area. Extracellular volume will be estimated from pre- and post-contrast T1 mapping and haematocrit.
