Trial summary

Rheumatic heart disease remains a major challenge in low and middle income countries. Early detection of clinically silent valvular lesions by screening echocardiography allows timely implementation of secondary antibiotic prevention, and may prevent progression of disease to severe valvular damage and heart failure.

About this study

Rheumatic heart disease remains a major challenge in low and middle income countries. Early detection of clinically silent valvular lesions by screening echocardiography allows timely implementation of secondary antibiotic prevention, and may prevent progression of disease to severe valvular damage and heart failure. The objective of the study is to assess the prevalence of rheumatic heart disease among schoolchildren in Arequipa, Peru. Subsequently, the investigators will evaluate progression of disease in children with early stages of subclinical rheumatic heart disease.

The investigators will perform a population-based observational survey for rheumatic heart disease using portable echocardiography among schoolchildren aged 5 to 16 years from randomly selected public and private schools. Rheumatic heart disease will be documented both according to the modified World Health Organization definition and the echocardiographic criteria suggested by the World Heart Federation.

Background

Rheumatic fever complicated by rheumatic heart disease continues to be a major contributor to morbidity and premature death in low- and middle-income countries where it accounts for up to a quarter of a million deaths every year. Rheumatic fever results from an autoimmune response to groups A streptococcal pharyngitis and may progress to rheumatic heart disease with cumulative exposure. Data on prevalence of rheumatic heart disease in Latin America is scarce and ranges from 1.3/1000 as assessed by cardiac auscultation to 4.1/1000 as assessed by echocardiography.

Secondary antibiotic prevention and inclusion of patients with rheumatic heart disease in a registry with close follow-up has been demonstrated to reduce the cardiovascular sequelae associated with disease progression.

The natural course of early, clinically silent stages of rheumatic heart disease is largely unknown. Disease regression has been reported in up to one third of children with early morphological valvular changes consistent with rheumatic heart disease.

Objective

The objective of the study is to assess the prevalence of rheumatic heart disease among schoolchildren in Arequipa, Peru. Subsequently, the investigators will investigate progression of disease in children with early stages of subclinical rheumatic heart disease.

Methods

The investigators will perform a population-based observational survey for rheumatic heart disease using portable echocardiography among schoolchildren aged 5 to 16 years from randomly selected public and private schools. Rheumatic heart disease will be documented both according to the modified World Health Organization definition and the echocardiographic criteria suggested by the World Heart Federation. Children diagnosed with rheumatic heart disease will be started on secondary antibiotic prevention and included into a prospective registry with longitudinal follow-up.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Apr 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Peru, Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Rheumatic heart disease according to WHO and WHF criteria (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02353663, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Apr 2016.
