Insights
Oral propranolol is a rapid and effective treatment for infantile hemangiomas in children. This medication demonstrated consistent efficacy across various patient demographics and hemangioma types with minimal side effects.
Area of Science:
- Pediatric Dermatology
- Pharmacology
- Vascular Anomalies
Background:
- Infantile hemangiomas (IH) are common benign vascular tumors in infants.
- Limited treatment options exist, with propranolol emerging as a promising therapy.
- Multicenter studies are crucial to validate propranolol's efficacy and safety in IH.
Purpose of the Study:
- To evaluate the efficacy and adverse effects of oral propranolol in treating infantile hemangiomas.
- To assess the treatment response across different patient and hemangioma characteristics.
- To determine the optimal dosage and duration for propranolol therapy in IH.
Main Methods:
- Retrospective analysis of 71 infants treated with oral propranolol (1 mg/kg every 12 hours) for at least 12 weeks.
- Photographic assessment of hemangioma severity using a standardized 10-point scale by five independent observers.
- Statistical analysis to determine treatment efficacy at various time points and across subgroups.
Main Results:
- Propranolol showed rapid and significant efficacy in reducing infantile hemangioma severity by 4 weeks (p < 0.001), with continued improvement up to 32 weeks.
- Treatment response was consistent regardless of infant's sex, age, hemangioma type (segmental/nonsegmental), location, ulceration, or depth.
- Adverse effects were minimal, with agitated sleep reported in only 10 of 71 patients.
Conclusions:
- Oral propranolol (2 mg/kg/day) is a well-tolerated and effective treatment for infantile hemangiomas.
- The drug's efficacy is not influenced by various clinical factors, suggesting broad applicability.
- Further prospective studies are warranted to establish the definitive role of propranolol in infantile hemangioma management.
Abstract:
Propranolol has been used successfully in a limited number of children with infantile hemangiomas. This multicenter retrospective study describes the efficacy and adverse effects of propranolol in infantile hemangioma. Seventy-one infants with infantile hemangiomas were treated with oral propranolol, 1 mg/kg/12 hours, for at least 12 weeks. A photograph based severity scoring assessment was performed by five observers to evaluate efficacy, utilizing a scoring system of 10 as the original infantile hemangioma before treatment and 0 as completely normal skin. The mean of the five independent measurements was used in the analysis. Propranolol was a rapid and effective treatment for infantile hemangiomas at 4 weeks (p < 0.001), at 8 weeks (p < 0.001 compared to the 4 wks value), at 12 weeks (p < 0.05 compared to the 8 wks value), and thereafter up to 32 weeks (p < 0.01 compared to the 16 wks value). The response of infantile hemangiomas to propranolol was similar regardless of sex, age at onset of treatment, type of involvement (segmental and nonsegmental), facial segments affected, special locations (eyelid, nasal tip, and parotid region), ulceration, and depth of infantile hemangiomas. Very few side effects were reported; mainly agitated sleep in 10 of 71 patients. In the series of patients in this study, oral propranolol 2 mg/kg/day was a well-tolerated and effective treatment for infantile hemangiomas. Prospective studies are needed to establish the exact role of propranolol in the treatment of infantile hemangiomas.
