INTRODUCTION: Infantile hemangioma (IH) is a common benign tumor in infants. While most cases exhibit a self-limiting nature, some require medical treatment to avoid complications. Propranolol is the first-line therapy for IH, it has a high success rate, and is safe to use. Unfortunately, some patients might experience rebound growth after propranolol discontinuation. Currently, it is unclear which factors predict this phenomenon. This study aimed to identify factors affecting the rebound growth of IH after propranolol cessation. We also aimed to identify predictors for an excellent response to oral propranolol.
METHODS: We performed a retrospective cohort study using clinical data from all patients referred to our clinic with IH and placed on systemic oral propranolol between January 2009 to December 2023 in the dermatology outpatient clinic of Rambam Healthcare Campus.
RESULTS: Out of a total of 552 patients with IH, 301 received oral propranolol for at least 6 months. A relapse phenomenon was observed in 38 (12.6%) patients. We found a significant association between limb involvement and the least likelihood of hemangioma rebound (p < 0.001). An excellent response to oral propranolol was observed in 57.8% of patients. Younger age at initiation of oral propranolol was associated with an excellent response (p = 0.015). Also, IHs located on the limbs (67) showed a higher rate of excellent response to oral propranolol compared to other anatomical sites (p = 0.02). Interestingly, patients who were treated with a dose of 2 mg/kg/day were associated with excellent response to treatment (p = 0.007).
CONCLUSIONS: IHs located on the limbs demonstrated less rebound growth and a better treatment response. When oral propranolol was initiated earlier or when the target dose was 2 mg/kg/day, there was a higher rate of excellent response to treatment.
