Propranolol Monotherapy in Multifocal/Diffuse Infantile Hepatic Hemangiomas in Indian Children: A Case Series.

INTRODUCTION

Infantile hepatic hemangioma (IHH) is the most common benign liver tumor in children, and multifocal and diffuse tumors often become life-threatening, necessitating therapy. Propranolol is now considered the first choice of therapy with ample data in Caucasian children. We present a series of nine Indian children with multifocal (n = 5) and diffuse (n = 4) IHH treated with propranolol monotherapy.

METHODS

This was a retrospective clinical data-based single-center study. Propranolol was used at a median dose of 3.2 mg/kg/day (range 3-3.3 mg/kg/day) for a median duration of 12 months (range 6-32 months).

RESULTS

The presentations of IHH (either in isolation or combination) were hypothyroidism in six patients (diagnosed by elevated serum TSH levels), heart failure in three (diagnosed based on clinical and echocardiographic features), and imaging evidence of macrovascular shunting in two patients. A good response to propranolol monotherapy (with a median dose of 3.2 mg/kg/day for a median duration of 12 months) was observed in eight patients, with a poor response in one. One patient experienced recurrence but responded adequately to propranolol retreatment.

CONCLUSIONS

Our data reiterate the excellent response (88.9% responded) and safety profile with propranolol monotherapy in complicated IHH and strengthen the data in Asian (Indian) children. It includes the maximum proportion of complicated IHH treated with propranolol in East and South Asia, and the largest series from India.
