Résumé :

Background: Cardiac involvement in children with human immunodeficiency virus (HIV) infection is a well-known entity and occurs clinically more often in patients with advanced acquired immunodeficiency syndrome (AIDS). Autonomic dysfunction is less known, especially in children. Hypothesis: The aim of this study was to asses the prevalence of cardiovascular abnormalities in a pediatric population with HIV. We also aimed to evaluate whether autonomic involvement occurs in the same population and is dependent on echocardiographic abnormalities. Methods: The occurrence of echocardiographic abnormalities was evaluated in 22 children with HIV infection, and five noninvasive tests were performed to evaluate the presence of autonomic dysfunction. Results: We found cardiac lesions in four children (18%), consisting of pericardial effusion in three children, wall motion abnormalities in three children, and acute aortic endocarditis in one child. All cardiac abnormalities were found at Stage C by Center for Disease Control (CDC) revised classification. We also found left ventricular filling pattern abnormalities consisting of E-wave maximal velocity decrease and prolonged deceleration time compatible with diastolic dysfunction. One of the five autonomic tests (Valsalva maneuver) was significantly altered, even in patients without abnormal echocardiography, suggesting mild autonomic dysfunction. Conclusion: The study demonstrated a high prevalence of cardiac lesions in children with HIV infection and indicated the presence of autonomic dysfunction even when there are no echocardiographically detected abnormalities.
