Aim: HIV infection in children is an important clinical and pathologic entity, which embraces many forms of presentation and can involve multiple organs and systems. This study aimed at identifying the main forms of cardiovascular involvement in HIV-infected children with horizontally transmitted disease and describing them with the aid of ultrasound and histopathological examinations.
Results: We recorded cardiovascular anomalies in 79 (67.52%) patients out of the 117 comprised in the study population, and noted the following prevalence distribution: systolic dysfunction in 49 (41.88%) patients, left ventricular hypertrophy (LVH) in 30 (25.6%) patients, right ventricular hypertrophy (RVH) in 15 (12.82%) patients, and dilated cardiomyopathy (DCM) in 22 (18.8%) patients. We also carried out post-mortem histopathological examinations in five patients, and observed the main modification incurred by the disease.
Conclusions: Cardiac involvement during HIV infection differs significantly in different mechanisms of virus transmission, and the horizontal transmission of HIV yields a lower prevalence of this type of pathology. The general diagnostic picture can be significantly improved by adding histopathological examination to the ultrasonographic method of investigation.
