Abstract
BACKGROUND: Renin-angiotensin system components have been demonstrated in the biology of infantile hemangioma (IH). Captopril, an angiotensin-converting enzyme inhibitor, is proposed as a therapeutic alternative to oral propranolol. OBJECTIVES: We sought to compare the benefit of propranolol and captopril in the treatment of IH, and to assess angiotensin-converting enzyme gene polymorphism in patients with IH and in control subjects. METHODS:Thirty patients with IH and 35 healthy control subjects were enrolled in this study. Patients were randomly assigned to treatment with either propranolol or captopril. Assessment was done clinically and by measurement of serum vascular endothelial growth factor and angiotensin II in patients and control subjects. Angiotensin-converting enzyme gene polymorphism was also studied. RESULTS: Clinical improvement was significantly better and faster in the patients treated with propranolol. Both groups showed reduced vascular endothelial growth factor and angiotensin II levels posttreatment, with a significantly higher percentage reduction in the propranolol-treated group. Cardiac side effects were reported only in the captopril-treated group. Baseline vascular endothelial growth factor level was significantly higher, and baseline angiotensin II level was significantly lower, in patients than control subjects. LIMITATIONS: We studied a relatively small number of patients and control subjects. CONCLUSION:Propranolol shows greater benefit than captopril in the treatment of IH.
