Serum Brain Natriuretic Peptide Levels and Pulmonary Hypertension in Pediatric Sickle Cell Patients

Akron Children's Hospital21 enrolled

Overview

The purpose of this study is 1. To determine if Brain natriuretic peptide levels correlates with elevated tricuspid regurgitation flow velocity levels in pediatric patients with sickle cell disease 2. To determine the role of age, gender, steady state hemoglobin and disease type on Brain natriuretic peptide levels and pulmonary hypertension

Pulmonary hypertension is recognized as a significant cause of morbidity and mortality in patients with sickle cell disease. Doppler echocardiography is a recommended noninvasive screening tool for sickle cell disease patients with pulmonary hypertension. Brain natriuretic peptide levels have been found to be a possible serum screening marker. This research will offer the opportunity to determine if there is any possible relationship between magnitude of BNP concentration and degree of TRV, if it can be used as a screening test in SCD pediatric patients with PHT and form the basis for a future multicenter study

Outcomes

Primary Outcomes

Correlation of Brain Natriuretic Peptide (BNP) levels to elevated Tricuspid Regurgitation Flow Velocity (TRV)

Subjects will be asked to participate in the study by allowing a review of their echocardiographic findings. In addition, they will be asked for a 1 ml blood sample during routine annual follow ups for BNP levels to be drawn.
