Propranolol vs. steroids in the treatment of infantile hemangiomas: A meta-analysis

Historical and contemporary management of infantile hemangiomas: a single-center experience

Objective: This study explores the 22-year evolution of Infantile Hemangiomas (IHs) treatment strategies at a single-center hospital, aiming to establish an individualized IHs management protocol. Methods: Retrospective review of IHs infants 2000-2022 at the Department of Plastic Surgery, Jiangxi Provincial Children's Hospital. Results: In our study of 27,513 IHs cases, 72.2% were female, with the median age at first hospital visit being 25 days. The majority of cases had localized and superficial lesions primarily on the head, face, and neck (67.5%). Ulceration rates fell from 21.1% to 12.6% with the introduction of propranolol. Management strategies have shifted over time, with the proportion of cases undergoing expectant management dropping from 32.9% to 12.4%. Since 2008, 26.1% of patients were treated with oral propranolol, largely replacing corticosteroids. Topical β-blockers have been used in 12.1% of cases, leading to a reduction in local injection therapy from 20.8% to 13.2%. Laser therapy, introduced in 2016, has been used in 13.8% of cases, while surgical excision has dropped from 25.0% to 8.5% due to alternative treatment options. Combination therapy was used in 8.8% of cases post-2015, indicating a rising trend. Drawing from the evolution of IHs management strategies, an individualized protocol for the management of IHs was successfully established. Conclusion: Treatment for IHs has evolved over recent decades, with less invasive medical interventions increasingly replacing more invasive methods. Furthermore, a personalized treatment protocol established in this study could boost the cure rate of IHs while minimizing potential side effects and complications.

Can Propranolol Affect Platelet Indices in Infantile Hemangioma?

INTRODUCTION

Propranolol, a nonselective beta-blocker used in the medical treatment of infantile Hemangioma (IH), has been shown to decrease the levels of vascular endothelial growth factor and reduce angiogenesis with its antiproliferative and antiangiogenetic effects.

MATERIALS AND METHODS

It has been reported that the storage, transport, and secretion of vascular endothelial growth factor (VEGF) are associated with platelet volume indices (PVI). We aimed to investigate the effect of propranolol on PVI in IH patients. Propranolol treatment was started on 22 IH patients. Platelets, mean platelet volume (MPV), platelet distribution width (PDW), and plateletcrit values in the follow-ups at months 0, 1, and 2 were compared between 22 patients who received treatment and 25 patients who did not.

RESULTS

While a statistically significant difference between months 0, 1, and 2 in PDW and MPV values was detected in the treated group, it was not detected in the untreated group. Taking into consideration that VEGF levels were higher at the beginning of the treatment in the pathophysiology of the disease, it was thought that the decrease in VEGF levels by propranolol may have led to a decrease in MPV and PDW levels in the treatment group.

CONCLUSION

Consequently, in IH cases, propranolol response follow-up can be evaluated with PVIs, especially MPV and PDW, and it may facilitate clinicians' monitoring of the disease after propranolol administration.

Safety of oral propranolol for neonates with problematic infantile hemangioma: a retrospective study in an Asian population

Although the efficacy of propranolol in the treatment of infantile hemangioma (IH) has been well established, clinical data on the safety and tolerability of propranolol in neonates are still lacking. In this work, clinical data of 112 neonates with IH were analyzed retrospectively. All of the patients were evaluated in the hospital at the beginning of the treatment and later in outpatient settings during the treatment. Each time, the following monitoring methods were applied: physical examination, ultrasound echocardiography (UCG), electrocardiography (ECG), blood pressure (BP), heart rate (HR), and basic laboratory tests including blood glucose (BG), liver function, blood potassium, thyroid function. There was a significant reduction in BP and HR at the initiation of treatment. The incidences of bradycardia and hypoglycemia were observed to be increased with the prolong duration of treatment, but not prolonged PR interval. During the course of the therapy, the risk of hyperkalemia and hypothyroidism was reached maximum at the 2 months and 3 months, respectively. Physical growth index including average height, weight and head circumference was not influenced by the treatment. The observed adverse effects were majority mild and only 3 patients needed to rest for 7 days due to severe diarrhea before restarting treatment. This study demonstrated that propranolol is safe and well-tolerated by properly selected young infants with IH. No serious adverse events were observed.

Intralesional steroid in the era of propranolol for infantile hemangioma-Do we need it?

INTRODUCTION

Despite its effectivity, there are reports of poor response to propranolol in the treatment of infantile hemangioma (IH). The literature is limited to the type of IH that fails to respond to propranolol. This study was conducted to analyze which types of hemangiomas respond poorly to propranolol and the effects of intralesional triamcinolone (IL TMC) in them.

MATERIAL AND METHODS

In this prospective cohort study, IH was classified as superficial, deep, and mixed. The clinical details were recorded. Propranolol was started in the patients at a dose of 1 mg/kg/day and increased to 2-3 mg/kg/day. The response to the treatment was evaluated as excellent, good, poor, and no response. IL TMC was given in the non-responding group at a dose of 1-2 mg/kg at one-month interval for a total of six doses after stopping propranolol.

RESULTS

Ninety-six patients (median age, 7 months; M/F = 2:1) were treated. Superficial hemangioma was present in 40 (41.7%), deep in 10 (10.4%), and mixed in 46 (47.9%) patients. The response was statistically better if initiated within four months of age. It was not influenced by the sex, number, site, or size. The response was statistically better in superficial hemangioma. IL TMC was administered in the 16 patients. The response was good or excellent in 10 patients.

CONCLUSION

Propranolol will be used as a first-line drug for IH. All superficial IHs are likely to respond. There will be a possibility of non-responding mixed or deep IH. Use of IL TMC seems reasonable for IH not responding to propranolol.

Celecoxib induces adipogenic differentiation of hemangioma‑derived mesenchymal stem cells through the PPAR‑γ pathway in vitro and in vivo

Infantile hemangioma (IH) is a benign tumor that produces a permanent scar or a mass of fibro-fatty tissue after involution in 40-80% of cases. Celecoxib is an inhibitor of cyclooxygenase-2 (COX-2), and can inhibit angiogenesis and fibrosis. The present study aimed to clarify whether celecoxib is able to induce tumor regression with minimal side effects. For that purpose, the regulation of celecoxib in the involution of IH was investigated in an IH model. Hemangioma-derived mesenchymal stem cells (Hem-MSCs) were isolated from proliferating specimens, and an IH model was established by injecting these cells into nude mice. Celecoxib was administered in vitro and in vivo. Oil Red O staining and reverse transcription-quantitative-PCR were used to detect the adipogenic differentiation of Hem-MSCs. Histologic analysis and immunohistochemical staining of the tumor xenografts were performed to investigate the pathological evolution of the tumor. The results showed that celecoxib inhibited the proliferation and induced the adipogenic differentiation of Hem-MSCs in vitro. In vivo, adipocytes were only present in the celecoxib group at week 4, while a larger number of fibroblasts and collagenous fibers could be observed in the basic fibroblast growth factor group. Therefore, celecoxib may be a potential agent used for IH treatment by inducing adipogenesis and inhibiting fibroblast formation.

Infantile Hemangioma Treated with Oral Propranolol: Case Presentation

Infantile hemangiomas (IHs) are the most common vascular tumors in childhood. We report the use of propranolol to treat the growth phase of IHs. Propranolol was given to a 6-month-old infant who presented with a 4-cm sharply demarcated hemangioma on his left gluteal region. After relevant evaluation, propranolol was prescribed with a starting dose of 1 mg/kg/day, given in 3 divided doses. Vital signs were monitored during the first 6 hours of treatment. In the absence of side effects, treatment was continued at home with 2 mg/kg/day for six months, and the child was reevaluated after 7 days of treatment and then monthly. After one month, effects on color and growth were noted. Complete healing occurred in less than 6 months. Side effects and relapse were not reported. Propranolol administered orally at 2 mg/kg/day was successful, leading to near resolution of the patient’s hemangioma.
