Effect of Oral Garlic on Arterial Oxygen Pressure in Children with Hepatopulmonary Syndrome

Abstract

Background: To study the effect of oral garlic on arterial oxygen pressure in children with hepatopulmonary syndrome.

Materials and Methods: Garlic powder in a capsule form was given to 15 children with hepatopulmonary syndrome (confirmed by contrast echocardiography) at the dosage of 1 g/1.73 m2 per day. Patients were evaluated clinically and by arterial blood gas every four weeks.

Results: The garlic capsule was administered to 15 patients with hepatopulmonary syndrome. There were 10 boys and 5 girls with a mean age of 9.4 ± 3.9 years. The underlying problems were biliary tract atresia (4 patients), autoimmune hepatitis (4 patients), cryptogenic cirrhosis (4 patients) and presinusoidal portal hypertension (3 patients). Eight patients (53.3%) showed an increase of 10 mmHg in their mean arterial oxygen pressure. The baseline PaO2 was 65.6 ± 12.1 mmHg in the responder group and 47.1 ± 11.2 mmHg in non-responder group. At the end of treatment the mean PaO2 in responders and non-responders was 92.2 ± 7.75 mmHg and 47.5 ± 11.87 mmHg, respectively (P ‹ 0.01).

Conclusions: Garlic may increase oxygenation and improve dyspnea in children with hepatopulmonary syndrome.
