Insights
Cardiac complications are common in children with human immunodeficiency virus (HIV) infection. This study found frequent echocardiographic abnormalities, including pericardial effusion and pulmonary hypertension, in Thai children with HIV.
Area of Science:
- Pediatrics
- Cardiology
- Infectious Diseases
Background:
- Cardiac complications significantly impact morbidity and mortality in children with human immunodeficiency virus (HIV) infection.
- Limited data exists on cardiac manifestations in HIV-infected children from developing nations.
Purpose of the Study:
- To assess clinical and echocardiographic findings in Thai children with HIV.
- To identify clinical predictors of left ventricular dysfunction and pulmonary hypertension in this population.
Main Methods:
- Retrospective review of medical records for 27 perinatally HIV-infected infants with cardiovascular issues.
- Data collected between 1995 and 2000 at a tertiary care hospital.
- Analysis included clinical signs, symptoms, and echocardiographic results.
Main Results:
- All patients presented with dyspnea; common symptoms included edema (44%) and finger clubbing (41%).
- Echocardiographic findings revealed high rates of pericardial effusion (44%), right ventricular dilatation (44%), and pulmonary hypertension (41%).
- Left ventricular dysfunction (37%) and dilatation (33%) were also observed. No correlation found between left ventricular dysfunction and HIV classification, age, nutrition, or symptoms.
Conclusions:
- HIV-infected children in Thailand exhibit significant cardiac abnormalities, including pulmonary hypertension and pericardial effusion.
- Left ventricular dysfunction in these children is not predicted by clinical factors or HIV disease stage.
Abstract:
Cardiac complications contribute significantly to morbidity and mortality in HIV-infected children. There have been few reports of cardiac manifestations in HIV-infected children in developing countries. The aims of this study were to evaluate the clinical manifestations and echocardiographic findings in Thai children with HIV infection and determine the clinical predictors of left ventricular dysfunction and pulmonary hypertension. We retrospectively reviewed the medical records of 27 infants infected with HIV perinatally who presented with cardiovascular problems at a tertiary care hospital between 1995 and 2000. The mean age at initial cardiac evaluation was 36 months (range 8-65). Signs and symptoms included dyspnoea in all cases, oedema in 12 (44%), finger clubbing in 11 (41%), cyanosis in 6 (22%) and S(3) gallop in 8 (30%). Echocardiographic abnormalities included pericardial effusion in 12 (44 %), right ventricular dilatation in 12 (44%), pulmonary hypertension in 11 (41%), diminished left ventricular fractional shortening in 10 (37%), left ventricular dilatation in 9 (33%) and combined ventricular dilatation in 2 (7%). Left ventricular dysfunction did not correlate with HIV CDC classification, age, nutritional status or clinical signs and symptoms.
