Use Of Propranolol For Treatment Research Articles

Propranolol for infantile haemangiomas: experience from a tertiary center.

Aim:Infantile haemangiomas are the most common tumor of infancy. We report the use of propranolol for treatment of problematic and complicated haemangiomas.Patients and Methods:Propranolol was given to 52 children with mean age of 18.2 months at onset of treatment. After clinical and electrocardiographic evaluations, propranolol was administered with a starting dose of 2 mg/kg per day, given in 3 divided doses. Monthly follow up was done, response to oral propranolol therapy and any complications of therapy were recorded. Response to propranolol was classified as Complete Response, Excellent Response, Partial Response and Non Responder.Results:Total 49 patients showed significant improvement after propranolol therapy out of which 4 patients were complete responder, 30 patients (56.7%) were excellent responders; 15 patients (28.8%) were partial responders. 3 patients (5.7%) had growth of haemangiomas despite propranolol therapy and were classified as non-responder. Side effect like hypotension, rashes, gastroesophageal reflux was reported by 3 patients. In our study mean duration of treatment was 6.5 months. At the end of treatment propranolol was stopped by with gradual tapering of dose over a period of 2 weeks.Conclusion:Propranolol administered orally at 2 mg/kg per day has rapid effective therapeutic effect in treatment of ulcerated haemangiomas and it appears to be a valuable and effective treatment option for infantile haemangiomas beyond the proliferative phase, and esthetically disfiguring haemangiomas.

Use of propranolol for treatment of infantile haemangiomas in an outpatient setting

Propranolol has recently emerged as an effective drug treatment for infantile haemangiomas. The side effect profile of the drug and the safety of administering propranolol in outpatient settings in this age group remain uncertain. We report our experience with 200 infants and children prescribed propranolol to treat infantile haemangiomas, including 37 patients considered to have a poor response to treatment. Patients were prescribed propranolol (1 mg/kg/dose bd) as outpatients at the Vascular Anomalies Service at the Royal Children's Hospital, Melbourne. The median age at commencement was 4 months (range 5 days-7 years). Twenty patients were older than 12 months at commencement. The median duration of treatment was 8 months. About 80% of treated haemangiomas were on the face. Approximately 50% of patients were considered to have an excellent response, 30% to have a good response and 20% to have a poor response. All segmental facial haemangiomas responded well. In contrast, 25% of focal facial haemangiomas responded poorly. Sleep disturbance was the most common side effect. Gross motor abnormalities including delayed walking were observed in 13 patients. Propranolol appears to be an effective treatment for infantile haemangiomas, particularly large segmental facial lesions. A poor response was seen in 20% of patients. Treatment has been provided in an outpatient setting without major complications and with excellent parental compliance. The side effect profile appears to be favourable, but further follow-up is required to identify unexpected long-term side effects.

Use of propranolol for treatment of hemangiomas in PHACE syndrome

We report the case of a 29-week preterm infant with PHACE (posterior fossa malformations, hemangionas, arterial anomalies, cardiac anomalies, eye anomalies) syndrome. PHACE syndrome is a neurocutaneous disorder with large facial segmental hemangionas associated with anomalies of the brain, eye, heart and aorta. The hemangiomas in our patient were problematic, distorting the airway and interfering with respirations to the point of requiring mechanical ventilation. Consultation with several different centers with medical expertize in treatment of congenital hemangiomas revealed different views on the best management strategy. In this infant, the hemangiomas progressed with failure to involute despite currently recommended therapy including corticosteroids and vincristine. Therefore, the infant was treated with propranolol and had significant regression of the hemangiomas. The use of propranolol for the treatment of infantile hemangiomas is reviewed.

Status of Propranolol for Treatment of Infantile Hemangioma and Description of a Randomized Clinical Trial

Our primary objective was to review the current use of propranolol for treatment of infantile hemangioma (IH), specifically regarding 1) the age at initiation of therapy, 2) the method of initiation, 3) the use of other adjuvant therapy, 4) the duration of therapy and relapse rate, 5) the adverse events, and 6) the outcome. Our secondary objective was to describe a randomized, controlled, single-blinded trial comparing propranolol to prednisolone for treatment of IH. Ovid Medline and PubMed searches were completed for the MeSH keywords "propranolol" and "hemangioma." Forty-nine English-language articles were published between June 2008 and September 2010, and 28 of these reported data from a total of 213 patients. Only 6 studies treated more than 10 patients, and these were selected for review in detail (154 patients). The treatment was initiated during infancy in 92.9% of patients (mean, 4.5 months). Sixty-five percent of patients were treated with 2 mg/kg per day, and 25.3% with 3 mg/kg per day. Patients were monitored overnight at initiation of treatment in 3 series (59 patients), for 4 to 6 hours as outpatients in 2 series (62 patients), and initially as inpatients but later as outpatients in 1 series (32 patients). Propranolol was used as sole therapy in about two thirds of patients (103 patients). Treatment was ongoing in 46% of patients at the time of publication. The average treatment duration in the remaining patients was 5.1 months. Rebound growth occurred in 21% of patients after a mean of 4.3 months of therapy. Adverse events occurred in 18.1% of patients and included hypotension in 6, somnolence in 6, wheezing in 4, insomnia, agitation, and/or nightmares in 6, cool hands or night sweats in 2, gastroesophageal reflux in 3, and psoriasis-like rash in 1. All authors reported a favorable outcome with propranolol, but the definition of efficacy was not standardized. Propranolol is an attractive alternative to other treatments for IH. Despite apparent widespread use of this medication, the data are limited, and prospective studies are lacking for this indication. The relatively high rate of adverse effects supports the need for careful monitoring of patients on this therapy. Fastidious reporting of adverse events and objective evaluation of early and late outcomes are necessary to improve our understanding of the use of propranolol for this indication.
