Doppler echocardiographic evaluation of pulmonary arterial pressure in children with allergic rhinitis.

Abstract：

:In children, persistent upper airway obstruction may lead to increased pulmonary arterial pressure (PAP). Allergic rhinitis (AR) is one of the frequent cause of persisting upper airway obstruction by nasal blockage in childhood. Regular use of nasal topical corticosteroids are effective in reducing nasal blockage and obstruction. However, whether symptomatic children with AR have increased PAP and curative effect of topical steroids are not known. The aims of this study were to clarify whether children having active symptoms of AR have increased PAP and to investigate the curative effect of reducing nasal obstruction by topical corticosteroids. Twenty-three children, aged between 5 and 16, diagnosed as AR, consisted of 17 seasonal AR (SAR) and seven perennial AR (PAR), were included in the study. Nineteen age and sex matched healthy children were received as controls. PAP was measured by using Doppler echocardiography in all subjects and symptom scores of AR were recorded in rhinitis group. After first evaluation, nasal steroid, budesonid, was given to rhinitis group for three months. Mean systolic PAP was 33.4+/-3.1 for children with AR mmHg and 23.6+/-4.3 mmHg for the control group. The difference was statistically significant (P<0.05). Mean systolic PAP of children with PAR was significantly higher than children with SAR (P<0.05). In rhinitis group, mean PAP decreased significantly after relief of upper airway obstruction by nasal corticosteroid therapy to normal level of 24.9+/-3.6 mmHg (P<0.05). Our results showed that children with AR may have significantly higher PAP than healthy subjects and decreased to normal levels after relieving nasal blockage by nasal corticosteroids. Nevertheless, Doppler echocardiography is a safe, non-invasive and practical tool for cardiac investigation of children with AR. Therefore, in symptomatic period, evaluation of PAP of children with AR by using Doppler echocardiography may be useful in the planning and following of their therapy.
