Insights
Oral propranolol treatment for infantile hemangioma (IH) significantly reduces serum vascular endothelial growth factor (VEGF) levels, particularly within the first month. This finding offers insight into the therapeutic mechanism of propranolol for IH.
Area of Science:
- Vascular Biology
- Pediatric Dermatology
- Pharmacology
Background:
- Infantile hemangioma (IH) is a common pediatric vascular tumor.
- Oral propranolol is the established first-line treatment for IH.
- The precise mechanism by which propranolol treats IH is not fully understood.
Purpose of the Study:
- To investigate the impact of oral propranolol on serum vascular endothelial growth factor (VEGF) levels in patients with infantile hemangioma.
- To explore the relationship between VEGF levels, lesion size, and treatment response.
Main Methods:
- A cohort of 22 patients with infantile hemangioma receiving propranolol therapy was studied.
- Serum VEGF levels were measured using enzyme-linked immunosorbent assay at baseline, 1 month, and 3 months post-treatment.
- Correlation analysis was performed between VEGF levels, lesion size, and patient age.
Main Results:
- Serum VEGF concentrations were significantly higher in patients with proliferative hemangiomas compared to venous malformations and healthy controls.
- A significant decrease of 21.6% in serum VEGF levels was observed after 1 month of propranolol treatment (p = 0.003).
- VEGF levels showed a significant positive correlation with infantile hemangioma lesion size (R = 0.43, p = 0.046).
Conclusions:
- Oral propranolol treatment leads to a reduction in serum VEGF levels in patients with infantile hemangioma.
- The observed decrease in VEGF may contribute to the therapeutic efficacy of propranolol in IH.
- Serum VEGF levels are positively correlated with lesion size in infantile hemangioma.
Abstract:
Oral propranolol is the first-line therapy for infantile hemangioma (IH), but its mechanism of action remains unclear. The aim of this study was to evaluate the change in serum vascular endothelial growth factor (VEGF) levels in patients with IH who underwent propranolol treatment. The study included 22 patients with IH receiving propranolol treatment. At three time points-before treatment and 1 and 3 months after treatment-blood samples were examined by enzyme-linked immunosorbent assay for serum VEGF expression. The mean serum VEGF concentration in children with proliferative hemangiomas was 395.0 ± 176.7 pg/mL, approximately twice as high as in patients with venous malformations (mean 170.7 pg/mL) and in healthy controls (204.8 pg/mL, p = 0.006). After 1 month of propranolol treatment, the level had fallen 21.6% (p = 0.003), although the downward trend was less obvious after 3 months of treatment (18.0%, p = 0.63). VEGF expression correlated significantly with the lesion size (correlation coefficient [R] = 0.43, p = 0.046), whereas no correlation was observed with age (R = 0.13, p = 0.56). Serum VEGF levels were higher in patients with IH and fell after 1 month of oral propranolol treatment. Similar results, although less pronounced, were found after 3 months of treatment. Lesion volume and serum level of VEGF were significantly correlated.
