Treatment with propranolol for infantile hemangioma in 13 Taiwanese newborns and young infants

Safety assessment of propranolol for infantile hemangioma: a study in an Asian population

OBJECTIVE

To evaluate the safety of initiating and maintaining propranolol therapy for infantile hemangioma (IH) and the safety of different doses.

METHODS

The retrospective analysis included 336 consecutive cases of infants with IH treated between January 2016 and October 2017. The patients were assessed in the hospital at the initiation of the therapy and later in outpatient settings during the therapy. The monitoring included blood pressure (BP), heart rate (HR), blood glucose, hepatic and renal function, myocardial enzymes and serum lipids. Cardiac examinations in the outpatient follow-up included electrocardiography, ultrasound echocardiography, height, weight and head circumference.

RESULTS

Propranolol decreased BP and HR at the initiation of treatment. The incidences of sinus bradycardia and hypoglycemia increased with the time of administration. Mean height, weight and head circumference were not affected during the treatment. The incidence of PR prolongation was 0%-5.7%. The effect of propranolol on the cardiovascular system, metabolism and physical development was not affected by its dose.

CONCLUSION

Oral propranolol is a safe treatment for IH. Serious side effects were not observed. Attention should be paid to the side effects during clinical treatment.

Oral Propranolol in Infantile Hemangiomas: Analysis of Factors that Affect the Outcome

Aim

The primary treatment for the subset of infantile hemangiomas (IHs) which develops complication is pharmacological intervention, and propranolol has become a popular choice. Here, we evaluated the efficacy and safety of propranolol in a clinical cohort of IHs and analyzed clinical characteristics associated with a good outcome.

Materials and Methods

We retrospectively reviewed a total of 52 IHs patients, between ages 1 and 48 months (median age: 7.5 months), who were treated with oral propranolol, with dose ranging from 2 to 3 mg/kg/day. Efficacy was evaluated using mean percentage reduction, visual analog scale (VAS), and parental satisfaction levels at week 2 and months 1, 2, 6, and 12. The adverse effects were noted and responses after 6 months were graded. Statistical analyses of the outcome were also performed for the responses with regard to age at propranolol initiation, site of lesion, and mean duration of treatment.

Results

A therapeutic response with at least 50% mean percentage reduction in size was noted in 84.6% at the end of 6 months. VAS score and parental satisfaction levels correlated well with mean percentage reduction (63.7 ± 15.6) at 6 months. Patients aged <6 months and those with cephalic lesions exhibited a greater therapeutic response rate with shorter overall mean duration of the treatment.

Conclusions

Oral propranolol at 2-3 mg/kg/day dosing has shown to be effective and safe for IHs in pediatric age group. Intervention in the early proliferative phase, with especially, the cephalic lesions result in better resolution rates with shorter duration of overall treatment.

Effects of systemic propranolol treatment on physical growth of patients with infantile hemangiomas

Propranolol has been widely used in the treatment of infantile hemangiomas since 2008. This study aimed to investigate complications of systemic propranolol therapy for infantile hemangiomas, especially its effect on infants' physical growth. In this study, propranolol was given at a dose of 2 mg/kg per day. Abnormal symptoms and growth parameters were recorded in detail during the therapy. Follow-up visits were arranged to continue at least through the age of 2 years. A total of 76 patients with complete growth parameters were enrolled into the study. Complications of propranolol were minor, and mainly included sleeping disorders, diarrhea, decrease in fasting glucose, bronchial hyperactivity and hyperkalemia. Four (5.26%) patients' growth curve dropped off more than 20 percentiles during therapy and half of them returned to normal after withdrawal of the medications. None of them suffered from underweight, wasting or stunning when medication was stopped. Systemic propranolol was proved to be a safe treatment for problematic infantile hemangiomas and did not affect the physical growth.

Safety of Oral Propranolol for the Treatment of Infantile Hemangioma: A Systematic Review

BACKGROUND AND OBJECTIVES

Given the widespread use of propranolol in infantile hemangioma (IH) it was considered essential to perform a systematic review of its safety. The objectives of this review were to evaluate the safety profile of oral propranolol in the treatment of IH.

METHODS

We searched Embase and Medline databases (2007-July 2014) and unpublished data from the manufacturer of Hemangiol/Hemangeol (marketed pediatric formulation of oral propranolol; Pierre Fabre Dermatologie, Lavaur, France). Selected studies included ≥10 patients treated with oral propranolol for IH and that either reported ≥1 adverse event or effect (AE) or planned to capture AEs. Data capture was standardized and extracted study design, demographic characteristics, IH characteristics, intervention, and safety outcomes. AEs were assigned a system organ class and preferred term.

RESULTS

A total of 83 of 398 identified literature records met the inclusion criteria, covering 3766 propranolol-treated patients. The manufacturer's data for 3 pooled clinical trials (435 propranolol-treated patients) and 1 Compassionate Use Program (1661 patients) were included. AE data were reported for 1945 of 5862 propranolol-treated patients. The most frequently reported AEs included a range of sleep disturbances, peripheral coldness, and agitation. The most serious AEs (atrioventricular block, bradycardia, hypotension, bronchospasm/bronchial hyperreactivity, and hypoglycemia-related seizures) were managed by decreasing doses or temporary/permanent discontinuation of propranolol. Limitations included the variety of included study designs; monitoring, collection, and reporting of AE data; small sample sizes for some articles; and the wide scope of review.

CONCLUSIONS

Oral propranolol is well tolerated if appropriate pretreatment assessments and within-treatment monitoring are performed to exclude patients with contraindications and to minimize serious side effects during treatment.

Propranolol in the Treatment of Infantile Hemangiomas: A Meta-Analysis in Chinese Patients

A meta-analysis was conducted to evaluate the efficacy of propranolol in the treatment of infantile hemangiomas (IHs) in Chinese infants. A statistically significant difference was found between infants treated using propranolol and those treated using corticosteroids (p < 0.001). The total effect pooled from 26 single-arm studies using meta-analysis of propranolol on IHs in Chinese infants was 93% (95% confidence interval 0.88, 0.96).

Increased apoptosis and secretion of tryptase by mast cells in infantile haemangioma treated with propranolol

Propranolol is increasingly used to treat problematic infantile haemangioma (IH), although its molecular mechanisms remain unclear. A key feature of propranolol therapy is the decreased deposition of fibrofatty residuum compared with spontaneously involuting IH. This study investigated the molecular consequences of propranolol treatment for IH in vivo.Immunohistochemical and terminal deoxynucleotidyl transferase dUTP nick end labelling (TUNEL) staining was performed on five age matched patients with proliferative IH. Two patients (A and B) were undergoing propranolol treatment at the time of surgical resection.Propranolol treatment increased apoptosis, and induced mast cells to degranulate and secrete tryptase into the interstitium. The microvessels of patient A were immature [weak von Willibrand Factor (vWF), and strong osteoprotegerin (OPG) staining], comparable to untreated proliferative IH, while those of patient B were mature (strong vWF staining, and no OPG staining). The perivascular CD90 mesenchymal stem cell population was preserved in both propranolol treated patients.Using rarely obtained biopsies from IH patients treated with propranolol, we show increased apoptosis by propranolol for the first time in vivo. We also suggest that mast cells, through secreted proteases, may contribute to the decreased fibrofatty residuum seen with propranolol treatment.

Propranolol in treatment of huge and complicated infantile hemangiomas in egyptian children

Background. Infantile hemangiomas (IHs) are the most common benign tumours of infancy. Propranolol has recently been reported to be a highly effective treatment for IHs. This study aimed to evaluate the efficacy and side effects of propranolol for treatment of complicated cases of IHs. Patients and Methods. This prospective clinical study included 30 children with huge or complicated IHs; their ages ranged from 2 months to 1 year. They were treated by oral propranolol. Treatment outcomes were clinically evaluated. Results. Superficial cutaneous hemangiomas began to respond to propranolol therapy within one to two weeks after the onset of treatment. The mean treatment period that was needed for the occurrence of complete resolution was 9.4 months. Treatment with propranolol was well tolerated and had few side effects. No rebound growth of the tumors was noted when propranolol dosing stopped except in one case. Conclusion. Propranolol is a promising treatment for IHs without obvious side effects. However, further studies with longer follow-up periods are needed.

Treatment of periorbital infantile haemangiomas: a systematic literature review on propranolol or steroids

AIM

The aim of this study was to compare the efficacy and safety of propranolol versus corticosteroids for the treatment of periorbital infantile haemangiomas (IHs).

METHODS

A literature review using PubMed, Ovid Medline, EBSCO, Springer, Web of Knowledge, Cochrane Library, CNKI and associated references before 2 March 2013 was conducted. The main outcomes were distribution of locations, response rate, rebound growth rate, spherical and cylinder power before and after treatment, amblyopia rate and adverse events.

RESULTS

Thirty-one studies including 425 patients met the inclusion criteria. A total of 70.6% of patients were female, 89.6% of the periorbital IHs were located in the upper or lower eyelid area. The most common administration routes involved oral propranolol and intralesional injection of corticosteroids. The mean response rate was 94.0% for propranolol and 82.3% for corticosteroid (P = 0.001). The rebound growth rate was 13.9% for propranolol and 12.0% for steroids (P = 0.71). Astigmatism was reduced in both propranolol and steroid studies (P < 0.0001, P < 0.0001), but a significant reduction in spherical power was only demonstrated in propranolol studies (P = 0.005). A total of 31.1% of patients treated with corticosteroids developed post-operative amblyopia compared with 16.7% of patients treated with propranolol (P = 0.04). Oral propranolol seemed to induce more temporary adverse events than intralesional corticosteroids administration (24.0% vs. 9.6%, P = 0.006).

CONCLUSION

Propranolol may represent an effective therapy for periorbital IHs compared with the use of corticosteroids; however, further randomised control studies are needed to compare adverse events.

Beta-blockers versus corticosteroids in the treatment of infantile hemangioma: an evidence-based systematic review

BACKGROUND

The efficacy and safety of beta-blockers versus corticosteroids in the treatment of infantile hemangiomas (IHs) is controversial. This study aimed to summarize evidence described in the literature and to assess the quality of studies involving beta-blockers and corticosteroids for the treatment of cutaneous IHs.

METHODS

Comparative studies were collected from 15 online electronic databases, including OVID Medline, PubMed, ISI Web of Science, CENTRAL, CNKI, ChiCTR, JPCTR, CTRIndia, IranCTR, SLCTR, ISRCTRN, NLCTR, GCTR, ANCTR, ClinicalTrial. gov, and associated references. Studies without a control group were excluded, and the remaining studies were assessed by two reviewers independently using the Downs & Black scale for reported quality. The main areas assessed in the included studies were volume changes, overall improvement in appearance, eye function, and adverse events.

RESULTS

Ten comparative studies were included with a total of 419 children. A meta-analysis was not performed due to the considerable heterogeneity across studies. Some evidence showed that beta-blockers are superior to steroids in reducing volume and improving the overall appearance of IHs, such as lightening of the color and flattening of the surface. Conclusions regarding improved eye function and adverse events were divided, and no consensus has been reached on the superiority of one treatment over another. No episodes of severe-onset asthma, hypotension, or bradycardia occurred in the beta-blocker treatment due to the rigorous exclusion of patients with contraindications.

CONCLUSIONS

Available studies indicate that beta-blockers are an alternative option to corticosteroids for IH treatment with respect to volume shrinkage and improvement in appearance. No evidence has shown a significant difference in improved eye function and adverse events between beta-blockers and corticosteroids in the treatment of IH; indeed, there is a lack of well-designed, high-quality randomized control trials.

Propranolol in use for treatment of complex infant hemangiomas: literature review regarding current guidelines for preassessment and standards of care before initiation of therapy

In 2008, the positive effects of propranolol on infantile hemangiomas (IH) have been discovered serendipitously by Léauté-Labrèze and her coworkers. Since then, propranolol has been in use in allday clinical practice worldwide for treatment of IH. It even caused some kind of paradigm shift in the overall management of these lesions, though propranolol is still not FDA approved, respectively, in “off-label” use for this indication in the majority of institutions. Thus, the aim of this communication is to evaluate the literature for current evidence regarding guidelines for preassessment and standards of care before initiation of therapy.

Preliminary experience on treatment of infantile hemangioma with low-dose propranolol in China

We aimed to assess the efficacy and safety of low-dose propranolol for treatment of infantile hemangiomas (IHs) in China. Our prospective study included data from 89 patients with IH, aged 1-12 months. Plasma renin activity, angiotensin II, and aldosterone were measured before initiation of propranolol therapy. Patients were administered propranolol (0.75-1 mg/kg/day) under close observation. The volume, texture, and color of lesions were used to evaluate efficacy. Safety endpoints included heart rate, systolic and diastolic blood pressures, alanine transaminase, aspartate transaminase, thyroid function tests, and fasting blood glucose. Adverse effects were recorded. Mean plasma angiotensin II concentration in patients with IH was higher than that in age-matched healthy children, whereas mean plasma renin activity was lower. Mean aldosterone level was higher at 1-3 months but lower at 4-12 months, than values reported previously. After propranolol therapy for 6 months, IH regression was classed as grade IV in 44 patients (49.4 %), grade III in 21 patients (23.6 %), and grade II in 24 patients (27.0 %); none were grade I. Mild adverse effects, including diarrhea, restless sleep, nausea, cold extremities, and hypoglycemia, occurred in 12 patients (13.5 %). Slight decreases in heart rate and blood pressure occurred in all patients (p < 0.05). The IHs of four patients (4.5 %) relapsed after treatment cessation at 4-5 months.

CONCLUSION

Low-dose propranolol is effective and safe for Chinese children with IH, and larger-scale studies are merited. Mechanisms underlying IH pathogenesis, and possible involvement of the renin-angiotensin-aldosterone system, deserve study.

Efficacy of topical brimonidine-timolol for haemangioma of infancy and perils of off-label prescribing

We report three patients with superficial haemangiomas treated topically with Combigan ophthalmic solution (brimonidine 0.2%-timolol 0.5%), a combination selective α-2-adrenergic agonist and non-selective β-blocker Food and Drug Administration-approved for use in glaucoma. Topical brimonidine 0.2%-timolol 0.5% therapy improved the appearance of haemangiomas in all the cases. Two patients did not experience any adverse effects. One patient had hypothermic episodes which were initially thought to be because of brimonidine 0.2%-timolol 0.5% therapy. However, an episode occurred a few weeks after discontinuation and brimonidine 0.2%-timolol 0.5% therapy was ruled out as a cause. Despite the benefit, off-label use of brimonidine 0.2%-timolol 0.5% therapy served as a pitfall in the evaluation of an unusual constellation of worrisome symptoms. In conclusion, brimonidine 0.2%-timolol 0.5% therapy is a promising alternative in the topical treatment of haemangiomas. It may have synergistic effects and increased efficacy by targeting haemangiomas via two mechanisms (α-agonism and β-inhibition), but the risk of unforeseen adverse effects must always be considered when prescribing off-label treatment, especially in infants.

Propranolol and infantile hemangiomas four years later: a systematic review

To systematically review the literature evaluating efficacy and adverse events of propranolol treatment for infantile hemangiomas, we searched the MEDLINE and Cochrane databases for all studies examining the response of infantile hemangiomas (IHs) to propranolol published between June 12, 2008, and June 15, 2012. Forty-one studies with 1,264 patients were included; 74% of patients were female and approximately 30% had received other treatments before propranolol. Propranolol was initiated at a mean age of 6.6 months at a mean dose of 2.1 mg/kg/day and for a mean treatment duration of 6.4 months. The response rate for patients with IHs treated with propranolol was 98% (range 82%-100%), with response rate defined as any improvement with propranolol. Treatment response rates were comparable for studies evaluating IHs at specific sites, such as periorbital IHs. Studies that followed patients after treatment completion reported IH rebound growth in 17% of patients. There were 371 adverse events reported in 1,189 patients. The most common adverse events were changes in sleep (n = 136) and acrocyanosis (n = 61). Serious adverse events were rare, with reports of symptomatic hypotension in five patients, hypoglycemia in four, and symptomatic bradycardia in one. This systematic review of 1,264 patients treated with propranolol for IHs showed a high rate of efficacy and a low rate of serious adverse events.
