Project description:BackgroundInfantile hemangioma (IH) is the most common benign tumor in children. However, few studies have reported the clinical features of segmental IH. We aimed to determine the clinical characteristics of segmental IH and to identify features that may aid clinicians in managing segmental IH.MethodsIn the cross-sectional prospective study approved by the Ethics Committee of the hospital, children diagnosed with IH were recruited, and information including patient demographics, IH morphology and anatomical location, complications and treatments were recorded and analyzed.ResultsIn total, 153 patients with segmental IH and 1375 patients with nonsegmental IH were enrolled in this study. The average age on the day of the first visit in patients with segmental IH was 3.63±3.23 months. In 69 patients (45.10%), segmental IH was diagnosed at birth. Most segmental IHs (49.67%) occurred in the limbs, while only 22.04% of nonsegmental IHs occurred in the extremities (P<0.001). Thirteen patients (8.50%) with segmental IH had ulceration. Compared with patients with nonsegmental IHs, patients with segmental IHs were more likely to be treated with oral drugs (P<0.001).ConclusionSegmental IHs mainly occur in the extremities and are frequently diagnosed at birth. Segmental IHs are usually accompanied by ulceration, which are more commonly seen in the neck and perineal/perianal/genital areas than nonsegmental IHs. Oral propranolol is prescribed more often in patients with segmental IH than in those with nonsegmental IH.

Project description:Infantile hemangioma (IH) is the most common infantile tumor, affecting 5-10% of newborns. Propranolol, a nonselective β-adrenergic receptor (ADRB) antagonist, is currently the first-line treatment for severe IH; however, both its mechanism of action and its main cellular target remain poorly understood. Since betablockers can antagonize the effect of natural ADRB agonists, we postulated that the catecholamine produced in situ in IH may have a role in the propranolol response. By quantifying catecholamines in the IH tissues, we found a higher amount of noradrenaline (NA) in untreated proliferative IHs than in involuted IHs or propranolol-treated IHs. We further found that the first three enzymes of the catecholamine biosynthesis pathway are expressed by IH cells and that their levels are reduced in propranolol-treated tumors. To study the role of NA in the pathophysiology of IH and its response to propranolol, we performed an in vitro angiogenesis assay in which IH-derived endothelial cells, pericytes and/or telocytes were incorporated. The results showed that the total tube formation is sensitive to propranolol only when exogenous NA is added in the three-cell model. We conclude that the IH's sensitivity to propranolol depends on crosstalk between the endothelial cells, pericytes and telocytes in the context of a high local amount of local NA.

Project description:Surgical specimens from children with infantile hemangioma or lymphatic malformations, as well as healthy appearing adjacent skin, were analyzed by microarray analysis of microRNA expression. Unsupervised hierarchical clustering was performed to identify microRNAs that were differentially expressed in IH compared to lymphatic malformations and skin 19 patients who underwent surgical excision of either a lymphatic malformation or infantile hemangioma were used in the study. 5 patients have multiple samples on the array and these duplicates are from different regions of the excised tissue or separate lesions as indicated. Tissue was snap frozen in liquid nitrogen and used for RNA extraction

Project description:Infantile hemangiomas are common vascular tumors with a specific natural history. The proliferation and regression mechanism of infantile hemangiomas may be related to the multilineage differentiation ability of hemangioma stem cells, but the specific mechanism is not well elucidated. KIAA1429 is an N6 -methyladenosine methylation-related protein that can also exert its role in a methylation-independent manner. This study aims to explore the function of KIAA1429 in infantile hemangiomas. qRT-PCR, western blotting, and immunostaining were performed to verify the expression of KIAA1429. The endothelial and fibroblast-like phenotypes of hemangioma endothelial cells were detected after KIAA1429 knockdown and overexpression. The stemness properties of hemangioma endothelial cells and the underlying mechanism of KIAA1429 in hemangiomas were also investigated. Nude mouse models of infantile hemangiomas were conducted to ascertain the effects of KIAA1429 in vivo. The results showed that KIAA1429 was highly expressed in infantile hemangiomas, particularly in involuting hemangiomas. In vitro experiments confirmed that KIAA1429 inhibited the endothelial phenotype, enhanced the differentiation ability, and promoted the fibroblast-like phenotype of hemangioma endothelial cells by inducing endothelial cell transition to facultative stem cells. However, the effect of KIAA1429 on the potential target was shown to be independent of N6 -methyladenosine methylation modification. Mouse models further revealed that KIAA1429 could inhibit the proliferation and promote the regression of hemangiomas. In conclusion, this study found that KIAA1429 played an important role in the regression of infantile hemangiomas by enhancing the stemness of hemangioma endothelial cells and could be a potential treatment target for infantile hemangiomas.

Project description:BackgroundIn view of the high incidence of infantile hemangioma (IH) in infants and young children, a comprehensive and reasonable evaluation scale for referral is urgently needed. This study compared the influence of the Hemangioma Severity Scale (HSS) and the Infantile Hemangioma Referral Score (IHReS) on treatment decisions for infantile hemangioma patients.ObjectiveWe aimed to establish a reliable and effective evaluation method for referral.MethodsThis was a prospective study to determine whether treatment was needed for IH patients after evaluation with the HSS and IHReS.ResultsA total of 266 consecutive referred IH patients were evaluated for the risk of IH, and the treatment rate was 80.8%. The area under the curve (AUC) of the subject receiver operating characteristic curve (ROC) of treatment decision making after referral by the HSS was 0.703 (95% CI: 0.634-0.772), and after referral by the IHReS was 0.892 (95% CI: 0.824-0.960).LimitationsThis was a single-center study.ConclusionsFor decisions regarding the treatment of IH patients, the IHReS has a higher efficiency and sensitivity than the HSS. However, the specificity of the IHReS is lower than that of the HSS.

Project description:Vessel proliferation underlies a number of serious pathological conditions. Infantile Hemangioma (IH) is a low-aggressive vascular tumor, interesting as an in vivo model of spontaneous tumor regression. Identifying mechanisms underlying IH spontaneous regression may then help to elucidate vessel-growth control, strongly deregulated in other serious conditions such as sarcoma, melanoma, diabetic retinopathy. The present study was aimed at identifying early regression indicators within hematological parameters. Thirty-four blood samples were collected from IH diagnosed babies (20-months median age), spontaneously regressing with age. Nineteen serum standard blood-tests were carried out using diagnostic reagents; in addition, serum-expression of 27 cytokine/chemokines was measured. Samples were divided in three age-groups, namely ≤ 12, 13 to 24 and >24 months-age, respectively. Red-cells count, Hemoglobin, Hematocrit, Neutrophils, Lymphocytes, MCP-1 and MIP-1beta were significantly different in the three age-groups, according to one-way ANOVA analysis. The same parameters showed a significant Pearson-correlation with age, supporting the direct link of age with IH-regression. ROC analysis showed that red-cells count, Hemoglobin, Hematocrit, MCP-1 and MIP-1beta levels significantly discriminate IH in the proliferating-phase from IH in the regressing-phase. Such data indicate for the first time that standard hematological tests and cytokine serum-expression values may effectively discriminate proliferating- from regressing-IH, unrevealing early regression signs, and demonstrate that standard blood-tests may have novel unsuspected diagnostic/prognostic relevance in altered vessel-growth conditions.

Project description:Infantile hemangioma is a common tumor of infancy. Although most hemangiomas spontaneously regress, treatment is indicated based on complications, risk to organ development and function, and disfigurement. The serendipitous discovery of propranolol, a non-selective β-adrenergic receptor blocker, as an effective means to regress hemangiomas has made this a first-line therapy for hemangioma patients. Propranolol has shown remarkable response rates. There are, however, some adverse effects, which include changes in sleep, acrocyanosis, hypotension, and hypoglycemia. Over the last few years, researchers have focused on understanding the mechanisms by which propranolol causes hemangioma regression. This has entailed study of cultured vascular endothelial cells including endothelial cells isolated from hemangioma patients. In this article, we review recent studies offering potential mechanisms of how various cell types found in hemangioma may respond to propranolol.

Project description:Infantile hemangioma (IH) was one of the most common vascular tumors during childhood. Long non coding RNAs (lncRNAs) play great roles in angiogenesis; the involvement of lncRNAs in hemangioma remains unknown. We aim to investigate the differential expression of lncRNA between hemangioma and the adjacent normal tissues, with a view to studying the biological function of lncRNAs and their involvement in the pathogenesis of hemangioma. The differential lncRNAs expression profiles of hemangioma were established by lncRNA microarray. Bioinformatic analyses were applied for further study of these differentially expressed lncRNAs. A total of 2116 differentially expressed lncRNAs were identified, among these lncRNAs, 1259 were up-regulated and 857 were down-regulated more than two-fold.
