Abstract

Objective

The present study aims to identify the role of inflammatory markers such as C-reactive protein, interleukin-6, and fractalkine in CHD-associated pulmonary hypertension in children.

Methods

This is a prospective review of 37 children with CHD-related pulmonary hypertension, 21 children with congenital heart defects, and 22 healthy children.

Results

Serum C-reactive protein and interleukin-6 levels were significantly higher in the children with CHD-related pulmonary hypertension (respectively, p=0.049 and 0.026). Serum C-reactive protein concentrations correlated negatively with ejection fraction (r=−0.609, p=0.001) and fractional shortening (r=−0.452, p=0.007) in the pulmonary hypertension group. Serum fractalkine concentrations correlated negatively with ejection fraction (r=−0.522, p=0.002) and fractional shortening (r=−0.395, p=0.021) in the children with pulmonary hypertension. Serum interleukin-6 concentrations also correlated negatively with Qs (r=−0.572, p=0.021), positively with Rs (r=0.774, p=0.001), and positively with pulmonary wedge pressure (r=0.796, p=0.006) in the pulmonary hypertension group. A cut-off value of 2.2 IU/L for C-reactive protein was able to predict pulmonary hypertension with 77.5% sensitivity and 77.5% specificity. When the cut-off point for interleukin-6 concentration was 57.5 pg/ml, pulmonary hypertension could be predicted with 80% sensitivity and 75% specificity.

Conclusion

Inflammation is associated with the pathophysiology of pulmonary hypertension. The inflammatory markers C-reactive protein and interleukin-6 may have a role in the clinical evaluation of paediatric pulmonary hypertension related to CHDs.
