Abstract

Background: Validated and reliable instruments to measure disease severity are needed to substantiate the benefit of therapies for infantile hemangioma. Two purpose-made systems have been described: the Hemangioma Activity Score (HAS) and the Hemangioma Severity Scale (HSS). Objective: We sought to compare the HAS with the HSS in terms of ease of use, accuracy, and outcome in infants treated with oral propranolol. Methods: A prospective study of 54 infants with infantile hemangioma was conducted from October 2009 to December 2012. Propranolol was initiated at 0.5 mg/kg/d and increased to 2 mg/kg/d on day 3. The HAS and the HSS were applied independently by 2 observers. Results: Intraclass correlation coefficients of the HAS and HSS between the observers was comparable but HSS scores often remained the same upon improvement of the infantile hemangioma and therefore did not reflect disease severity. HAS decreased over time, with a dramatic drop in the first week reflecting an immediate therapeutic response. Limitations: This is a single-institution study and there may have been some selection bias in the patients who were referred for treatment. Conclusions: This study suggests that the HAS is preferable to the HSS in evaluating infantile hemangioma response to treatment.
