Rešić A, Benco Kordić N, Obuljen J, Bašković M. Importance of Determining Vascular Endothelial Growth Factor Serum Levels in Children with Infantile Hemangioma. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1914. [PMID: 38003963 PMCID: PMC10673278 DOI: 10.3390/medicina59111914] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 09/10/2023] [Accepted: 10/27/2023] [Indexed: 11/26/2023]
Abstract
Background and Objectives: A potential role of vascular endothelial growth factor (VEGF) in the pathophysiology of infantile hemangiomas (IH) is thought to be plausible. The primary objective of this study was to investigate the importance of determining VEGF serum levels at various stages of IH growth in children. Materials and Methods: A nested case-control study was conducted. For the purposes of the researched target group, samples of fifty (N = 50) children with IH without associated diseases at different stages of hemangioma growth (proliferative and involutional stages) were used. The control group consisted of one hundred (N = 100) healthy children comparable in terms of age and sex, in whom the existence of IH and vascular malformations was ruled out via clinical examination. An immunoassay (ELISA) was used to determine VEGF serum levels in hemangioma growth's proliferation and involution phases. Results: A comparison of serum levels of VEGF in the phases of proliferation and involution in the group of patients with IH did not show a statistically significant difference (p = 0.171). The control group had significantly higher serum VEGF levels than the patient group in both the proliferation phase (p = 0.009) and the involution phase (p = 0.019). In the proliferation phase, a multivariate regression model explained 15% of the variance in the dependent variable, without significant predictor variables, while in the involution phase, it explained 21% of the variance in the dependent variable, and the history of invasive prenatal procedures stood out as a significant predictor variable positively associated with serum VEGF levels (beta coefficient = 0.33; p = 0.043). Conclusions: Although IH is thought to be the result of the dysregulation of angiogenesis and vasculogenesis under the influence of angiogenic factors, especially VEGF, this study did not demonstrate that VEGF serum levels in the proliferation phase of hemangioma growth were higher than those in the involution phase, or in relation to the control group.

Abstract
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.

Abstract
Local angiogenesis accompanies inflammation in psoriasis-affected skin. To determine the serum concentrations of selected pro- and anti-angiogenic factors and their interrelationships in patients with plaque psoriasis. The study included 41 men diagnosed with psoriasis, aged 43.5 ± 11.7 years. The Psoriasis Area and Severity Index score was 23.4 ± 5.2 points. The control group consisted of 38 healthy, age-matched men. The levels of pro-angiogenic cytokines and angiogenesis inhibitors, including fibroblast growth factor 1 (FGF-1), vascular endothelial growth factor A (VEGF-A), endostatin, and angiostatin, were determined from the serum of patients and controls using enzyme-linked immunosorbent assays. Compared with controls, patients with psoriasis had a significantly lower concentration of FGF-1 (P = .01) but higher concentrations of endostatin (P = .04) and angiostatin (P = .02). The concentration of VEGF-A was also higher in patients with psoriasis but not significantly (P = .25). The concentration of C-reactive protein (CRP) was significantly higher among patients with psoriasis than controls (P < .0001). Among controls, CRP concentrations did not correlate significantly with the concentrations of FGF-1, VEGF-A, endostatin, or angiostatin. Among patients with psoriasis, CRP concentrations correlated moderately with the concentrations of VEGF-A (r = .35; P = .02) and angiostatin (r = .31; P = .04). The concentration of VEGF-A correlated positively with PASI (r = .05; P = .0009) and BSA values (r = .39; P = .01). Psoriasis is associated with an altered systemic balance between pro-angiogenic and anti-angiogenic factors. The increase in serum angiogenesis inhibitors may be associated with unfavorable changes in the development of coronary collateral circulation. However, the clinical significance of this has not yet been established.

Abstract
Background: Infantile hemangioma is the most common tumor of infancy. Currently, propranolol is a preferred drug for treating hemangioma. The exact mechanism of action of propranolol is not known. In this study, we attempted to assess whether propranolol has any effect on vascular endothelial growth factor (VEGF) and tissue inhibitor of metalloproteinase-2 (TIMP-2) over a period of time, and if it is there, how long it affects it. Materials and Methods: Propranolol was administered in the dosage of 2–3 mg/kg. The first serum sample was collected before starting the propranolol treatment. Thereafter, samples were collected at monthly intervals up to a total of six samples. The samples were assessed for TIMP-2 and VEGF using enzyme-linked immunosorbent assay kit. Results: The duration of this study was from June 2016 to November 2017. The total number of patients in this study was 15. Thirteen patients responded to treatment. The mean age of patients was 7.1 months. The mean value of baseline VEGF was 0.234 ± 0.059 and that of TIMP-2 was 1.338 ± 0.679. As compared to baseline value, the P value was statistically not significant in any of sequential values. In category-wise analysis, apart from statistically significant value in the 6th month in excellent category and good response category in the 1st month, all other values did not reveal any significant change in VEGF analysis. The analysis of TIMP-2 revealed a significant change in the levels from Sample 2 to Sample 6 in the excellent response group; however, the levels did not show a specific trend either increasing or decreasing. Conclusion: Despite its beneficial action in regression of hemangioma, the exact mechanism is yet to be identified. The exact duration of treatment needs further evaluation.

Abstract
Hemangioma is a common benign tumor affecting infants. In this study, we prepared sodium morrhuate immunoliposomes through encapsulation of sodium morrhuate with liposomes coupled with an anti-VEGFR2/KDR antibody and examined its effect on the biology of human hemangioma endothelial cells (HECs). It was found that compared to the liposomal sodium morrhuate group, treatment with sodium morrhuate immunoliposomes facilitated cell detachment and apoptotic death. Confocal microscopy analysis revealed that sodium morrhuate immunoliposomes had a higher binding activity to HECs than liposomal sodium morrhuate. Apoptosis analysis further demonstrated that treatment with liposomal sodium morrhuate or sodium morrhuate immunoliposomes significantly induced apoptosis in HECs, compared to the control group. Western blot analysis revealed an induction of caspase-3 and caspase-9 levels and reduction of caspase-8 and Bcl-2 levels in HECs treated with liposomal sodium morrhuate or sodium morrhuate immunoliposomes. Taken together, these results indicate that sodium morrhuate immunoliposomes have an increased capacity to target HECs and promote mitochondrial apoptosis. Therefore, sodium morrhuate immunoliposomes may represent a promising agent in the treatment of hemangiomas.

Abstract
Background The aim of this study was to investigate the developmental mechanisms of infantile hemangioma (IH) from the microRNA level. Material/Methods A total of 63 biological specimens of IH were obtained from the First Affiliated Hospital of Jinzhou Medical University and we assessed related miRNAs. Magnetic bead sorting, endocytosis test, canalization assay, and immunofluorescence detection were performed. The IH-derived cells were transfected with related factors and then we assessed the apoptosis and invasion. Results The contents of MiR-455, miR-206, and miR-29a in the proliferative period group (PP) were lower than in the complete regression period group (CR) (P<0.05), and the content of miR-29a in the regression period group (RP) was lower than in the group CR (P<0.05). The post-sorting proliferation capacity was faster than in human umbilical vein endothelial cells, and IH-derived vascular endothelial cells (VECs) exhibited faster canalization ability. The cells transfected with miR-29a exhibited obvious apoptosis 48 h later, the cells transfected with miR-206 exhibited significantly reduced proliferation capacity as well as apoptosis 48 h later, and the invasion capacity was decreased 24 h after transfection. Conclusions miR-29a, miR-206, and miR-455 are differently expressed in different periods of IH, and may participate in regulating multiple functions during the progression of IH.

Abstract
Few preliminary reports studied the utility of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) for differentiation between infantile hemangiomas (IHs) and vascular malformations. The aim of this study was to investigate the role of serum VEGF and bFGF levels in differentiating IHs from vascular malformations and identifying the stage and clinical course of IHs. Serum levels of VEGF and bFGF were assessed in 60 infants and children with various cutaneous vascular anomalies defined in 3 groups: proliferating IHs (n = 25), involuting IHs (n = 23), and vascular malformations (n = 12), in comparison with their levels in 40 healthy matched control. Serum levels of VEGF and bFGF were significantly elevated in all groups as compared to control ( P < .001, respectively). Both proliferating and involuting IHs had comparable levels of both markers ( P > .05, respectively) that were significantly higher in comparison with vascular malformations ( P < .05, respectively). Significantly lower VEGF levels were found in IHs that had regressed spontaneously (n = 11) compared to those regressed by treatment (n = 37), ( P < .05); meanwhile, bFGF showed no significant difference between both groups ( P > .05). Using receiver operating characteristic curves, a combined use of VGEF and bFGF yielded a sensitivity of 85.42% and a specificity of 100% for differentiating IHs from vascular malformations. Serum VEGF and/or bFGF levels are increased in cutaneous vascular anomalies and can differentiate IHs from vascular malformations. None of these markers could help in identifying the stage of IHs. Low VEGF is associated with spontaneous regression of IHs.

Abstract
Propranolol, 2 mg/kg/day, is effective in the treatment of infantile hemangioma. We report the response to propranolol in infants with hemangioma at a dose of 1 mg/kg/day. Sixteen infants with newly diagnosed infantile hemangioma were given propranolol at a dose titrated from 0.5 mg/kg/day then increased to 1 or 2 mg/kg/day based on response to treatment until the lesions showed clinical stability for 3 consecutive months. Five out of 16 patients (31.2%) responded to propranolol at 1 mg/kg/day, while the remainder required 2 mg/kg/day for response. Vascular endothelial growth factor significantly decreased after treatment (median, 117.8 pg/mL; range, 35.3-468.7 pg/mL vs 59.2 pg/mL; range, 26.3-133.0 pg/mL; P = 0.016). Therefore, we recommend initiating treatment at 0.5 mg/kg/day for 2 days, then 1 mg/kg/day for 1 month. If the hemangioma has not decreased in size by 1 month follow up, the dose is subsequently increased to 2 mg/kg/day.

Abstract
Infantile hemangiomas as frequent infancy tumors have been a controversial issue of medical scientists worldwide. Their clinical aspects are various and their physiopathology is yet to be fully understood. Numerous publications outline the characteristics, causes, evolution possibilities and therapeutic approaches. Deciding whether to treat or not is the main question of this kind of pathology. Hemangiomas that have complications or can cause irreversible damage need therapy. This is a brief review of up-to-date information regarding the presentation of infantile hemangiomas and target-therapies.

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.

Abstract
The circulatory system is one of the first systems that develops during embryogenesis. Angiogenesis describes the formation of blood vessels as a part of the circulatory system and is essential for organ growth in embryogenesis as well as repair in adulthood. A dysregulation of vessel growth contributes to the pathogenesis of many disorders. Thus, an imbalance between pro- and antiangiogenic factors could be observed in infantile hemangioma (IH). IH is the most common benign tumor during infancy, which appears during the first month of life. These vascular tumors are characterized by rapid proliferation and subsequently slower involution. Most IHs regress spontaneously, but in some cases they cause disfigurement and systemic complications, which requires immediate treatment. Recently, a therapeutic effect of propranolol on IH has been demonstrated. Hence, this non-selective β-blocker became the first-line therapy for IH. Over the last years, our understanding of the underlying mechanisms of IH has been improved and possible mechanisms of action of propranolol in IH have postulated. Previous studies revealed that gap junction proteins, the connexins (Cx), might also play a role in the pathogenesis of IH. Therefore, affecting gap junctional intercellular communication is suggested as a novel therapeutic target of propranolol in IH. In this review we summarize the current knowledge of the molecular processes, leading to IH and provide new insights of how Cxs might be involved in the development of these vascular tumors.

Abstract
Despite multiple previous studies in the field of vascular anomalies, the mechanism(s) leading to their development, progression and maintenance has remained unclear. In this study, we have characterized the expression levels of vascular endothelial growth factors and their receptors in 33 human vascular anomalies. Analysis with quantitative real-time PCR and gene-specific assays showed higher expression of neuropilin-2 (NRP2) and VEGF-receptor-3 (VEGFR-3) mRNAs in vascular malformations (VascM) as compared to infantile hemangiomas (Hem). In addition, the expression levels of PlGF and VEGF-C mRNA were significantly higher in venous VascM when compared to the other VascM and Hem. Higher expression of NRP2 and VEGFR-3 were confirmed by immunohistochemistry. To further study the importance of NRP2 and VEGFR-3, endothelial cell (EC) cultures were established from vascular anomalies. It was found that NRP2 and VEGFR-3 mRNA levels were significantly higher in some of the VascM ECs as compared to human umbilical vein ECs which were used as control cells in the study. Furthermore, adenoviral delivery of soluble decoy NRP2 prevented the proliferation of ECs isolated from most of the vascular anomalies. Our findings suggest that NRP2 functions as a factor maintaining the pathological vascular network in these anomalies. Thus, NRP2 could become a potential therapeutic target for the diagnosis and treatment of vascular anomalies.

Abstract
Infantile hemangiomas (IH) are the most common eyelid and orbital tumors of childhood. Although they are considered benign lesions that have a generally self-limited course, in the periocular region, they have the potential to cause amblyopia, strabismus, and severe disfigurement. The decision for treatment can be a source of anxiety for patients, parents, and physicians alike. There are numerous treatment modalities, including emerging therapies that may make treatment safer and more effective than ever before. This review discusses our current understanding of this disease, its management, and future therapies.

Abstract
Infantile haemangioma therapy has long been a wait-and-see policy. Since recent development of laser and light therapy, pulsed dye laser has been successfully used for treating superficial haemangiomas. Few studies have been published about treatment with intense pulsed light (IPL) to assess the risk/benefit of IPL in the treatment of infantile haemangiomas during their early proliferative phase. In the present retrospective cohort study, we retrieved data about a series of 14 Caucasian children (median age: 4.8 months) with infantile haemangiomas treated with Photoderm Vasculight flash lamp. All patients experienced a rapid regression of the haemangiomas after 3 treatments on average. Few adverse events were noted, including ulceration and crusts. No residual scarring and cosmetic damages were noticed. Fast growing haemangiomas should be treated with light therapy as soon as possible. This technology is safe, efficient, inducing regression, and preventing any further functional and aesthetic complications. The benefit-risk ratio favours the treatment of most types of haemangiomas which are out of the scope of betablocker administration.

Abstract
A hallmark of infantile hemangioma, the most common tumor of infancy, is its dramatic growth after birth, by diffuse proliferation of immature endothelial cells, followed by spontaneous regression. The growth and involution of infantile hemangioma is quite different from other vascular anomalies, which do not regress and can occur at any time during life. Some hemangioma lesions can be extremely disfiguring and destructive to normal tissue and may even be life-threatening. Unfortunately, existing therapeutic approaches have limited success and significant adverse effects of some treatment modalities limit their use. Better understanding of the pathogenesis of hemangioma will enable the development of better therapeutic strategies. Here, we review recent studies and new hypotheses on the pathogenesis of the tumor. Detailed mechanisms of activated vascular endothelial growth factor signaling in tumor cells, identification of their origin and characterization of multipotent stem cells that can give rise to infantile hemangioma are shedding new light on this intriguing vascular tumor.

Abstract
Infantile haemangiomas (IH) are the most common benign tumours of infancy. Although most IH are innocuous and 85-90% regress spontaneously, some may become life- or function-threatening and require immediate treatment. Previous standard therapeutic options include physical measures (laser surgery, cryosurgery) and systemic corticosteroids, in severe cases also vincristine, alpha-interferon or cyclophosphamide, all bearing the risk of serious side-effects. Oral propranolol is a very recent therapeutic option for complicated IH with impressive efficacy and generally good tolerance. The effects of propranolol on IH were discovered by chance, and very little is known about its mechanisms of action in IH. Here we present a summary of current knowledge of how propranolol interferes with endothelial cells, vascular tone, angiogenesis and apoptosis. Early, intermediate and long-term effects of propranolol on IH can be attributed to three different pharmacological targets. Early effects (brightening of the haemangioma surface within 1-3 days after start of therapy) are attributable to vasoconstriction due to decreased release of nitric oxide. Intermediate effects are due to the blocking of proangiogenic signals (vascular endothelial growth factor, basic fibroblast growth factor, matrix metalloproteinase 2/9) and result in growth arrest. Long-term effects of propranolol are characterized by induction of apoptosis in proliferating endothelial cells, and result in tumour regression.
