<h4>Background</h4>Propranolol has become the first-line treatment for complicated Infantile Hemangioma (IH), showing so far a good risk-benefit profile.<h4>Case presentation</h4>We report the case of a toddler, on propranolol, who suffered cardiac arrest during an acute viral infection. She had a neurally-mediated syncope that progressed to asystole, probably because of concurrent factors as dehydration, beta-blocking and probably individual susceptibility to vaso-vagal phenomena. In fact a sig ...[more]

Project description:Infantile hemangiomas (IHs) are common neoplasms composed of proliferating endothelial-like cells. Despite the relative frequency of IH and the potential severity of complications, there are currently no uniform guidelines for treatment. Although propranolol has rapidly been adopted, there is significant uncertainty and divergence of opinion regarding safety monitoring, dose escalation, and its use in PHACE syndrome (PHACE = posterior fossa, hemangioma, arterial lesions, cardiac abnormalities, eye abnormalities; a cutaneous neurovascular syndrome characterized by large, segmental hemangiomas of the head and neck along with congenital anomalies of the brain, heart, eyes and/or chest wall). A consensus conference was held on December 9, 2011. The multidisciplinary team reviewed existing data on the pharmacologic properties of propranolol and all published reports pertaining to the use of propranolol in pediatric patients. Workgroups were assigned specific topics to propose protocols on the following subjects: contraindications, special populations, pretreatment evaluation, dose escalation, and monitoring. Consensus protocols were recorded during the meeting and refined after the meeting. When appropriate, protocol clarifications and revision were made and agreed upon by the group via teleconference. Because of the absence of high-quality clinical research data, evidence-based recommendations are not possible at present. However, the team agreed on a number of recommendations that arose from a review of existing evidence, including when to treat complicated IH; contraindications and pretreatment evaluation protocols; propranolol use in PHACE syndrome; formulation, target dose, and frequency of propranolol; initiation of propranolol in infants; cardiovascular monitoring; ongoing monitoring; and prevention of hypoglycemia. Where there was considerable controversy, the more conservative approach was selected. We acknowledge that the recommendations are conservative in nature and anticipate that they will be revised as more data are made available.

Project description:The purpose of this study was to compare long-term neurocognitive functioning (working memory, processing speed, and attention) between children who had been treated with either propranolol or atenolol for infantile hemangioma during infancy. All eligible children (n = 158) aged 6 years or older and treated with propranolol or atenolol as infants were invited to participate in this two-center cross-sectional study. The primary outcome was the Wechsler Intelligence Scale for Children-V Cognitive Proficiency Index (CPI), a measure of working memory, processing speed, and attention. Secondary outcomes were general intelligence, auditory, visuospatial, and narrative memory, as well as executive functioning and sleep. A total of 105 children, of whom 36 had been treated with propranolol (age 6.0-11.8 years, follow-up time 1.6-9.7 years, 19% male) and 69 had been treated with atenolol (age 6.9-9.7 years, follow-up time 4.5-8.4 years, 19% male), were analyzed. The CPI and other neurocognitive outcomes did not differ between the propranolol and atenolol groups and were in line with general population test norms. Post hoc analyses revealed lower CPI scores for males, both compared to participating females (10.3 IQ points, medium effect size) and compared to matched test norms (12.4 IQ points, medium effect size).Conclusions Long-term neurocognitive functioning did not differ between children treated with propranolol and those treated with atenolol for IH. Overall, propranolol and atenolol appear to be safe treatments for IH regarding long-term neurocognitive functioning. The substantially lower CPI scores in males warrant further investigation.Trial registration Netherlands Trial Register, NL7703 https://www.trialregister.nl/trial/7703 What is Known: • Infants with infantile hemangioma are effectively treated with propranolol or atenolol. • Parents and professionals are concerned about long-term neurocognitive effects.What is new• No long-term (≥ 6 years) differences in neurocognitive functioning were found between children treated with propranolol or atenolol. • Males treated with beta-blockers had substantially lower IQ scores than treated females and males from the general population, which is a matter of concern and should be considered when evaluating the risk/benefit ratio in less severe forms of infantile hemangioma.

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 hemangiomas (IHs) are non-malignant, largely cutaneous vascular tumors affecting approximately 5-10% of children to varying degrees. During the first year of life, these tumors are strongly proliferative, reaching an average size ranging from 2 to 20 cm. These lesions subsequently stabilize, undergo a spontaneous slow involution and are fully regressed by 5 to 10 years of age. Systemic treatment of infants with the non-selective β-adrenergic receptor blocker, propranolol, has demonstrated remarkable efficacy in reducing the size and appearance of IHs. However, the mechanism by which this occurs is largely unknown. In this study, we sought to understand the molecular mechanisms underlying the effectiveness of β blocker treatment in IHs. Our data reveal that propranolol treatment of IH endothelial cells, as well as a panel of normal primary endothelial cells, blocks endothelial cell proliferation, migration, and formation of the actin cytoskeleton coincident with alterations in vascular endothelial growth factor receptor-2 (VEGFR-2), p38 and cofilin signaling. Moreover, propranolol induces major alterations in the protein levels of key cyclins and cyclin-dependent kinase inhibitors, and modulates global gene expression patterns with a particular affect on genes involved in lipid/sterol metabolism, cell cycle regulation, angiogenesis and ubiquitination. Interestingly, the effects of propranolol were endothelial cell-type independent, affecting the properties of IH endothelial cells at similar levels to that observed in neonatal dermal microvascular and coronary artery endothelial cells. This data suggests that while propranolol markedly inhibits hemangioma and normal endothelial cell function, its lack of endothelial cell specificity hints that the efficacy of this drug in the treatment of IHs may be more complex than simply blockage of endothelial function as previously believed.

Project description:BackgroundInfants with infantile hemangioma (IH) have been effectively treated with propranolol or atenolol. Concerns were raised about the mental health of these children at school age, due to central nervous system effects of propranolol and visible nature of IH.ObjectiveThis study aimed to compare the mental health at school age of children treated with propranolol to children treated with atenolol for IHs and their parents.MethodsThis two-centered cross-sectional study included children aged ≥6 years and treated with either propranolol or atenolol for IH during infancy. Children's outcomes were performance-based affect recognition (Dutch version of the Developmental Neuropsychological Assessment-II [NEPSY-II-NL]), parent-reported emotional and behavioral functioning (Child Behavioral Checklist [CBCL]), and health-related quality of life (KIDSCREEN-27). Parents' outcome was parenting stress (Parenting Stress Questionnaire [OBVL]).ResultsData of 105 children (36 propranolol, 69 atenolol; 6.0-11.8 years) were analyzed. Mental health outcomes did not differ between both β-blocker groups. Although overall functioning was in line with norms, children presented specific problems concerning affect recognition, parent-reported attention, and social quality of life. Parents showed increased physical symptoms, depressive symptoms, and parent-child relationship problems.ConclusionNo difference in mental health at school age was found between children treated with propranolol or atenolol for IH. Although few overall mental health problems were found, specific problems require follow-up. Follow-up of children should be directed toward affect recognition, attention, and social functioning in daily life. Problems reported by parents could be ameliorated by mental health support during and after their infant's β-blocker treatment.

Project description:PurposeInfantile hemangiomas (IH) are the most common benign vascular tumors of infancy. Ocular complications due to orbital IH include strabismal, deprivational, or anisometropic astigmatism, and visual loss secondary to amblyopia.ObservationsWe report a case of a two-month-old female infant with a severe deep orbital IH. The diagnosis was established by clinical examination and magnetic resonance imaging (MRI). The patient was treated with oral propranolol for six months. Complete tumor regression was observed clinically and by MRI following the treatment. The patient showed no adverse effects or tumor recurrence at the 14-month follow-up.Conclusions and importanceDespite its benign nature, periorbital IH requires a rapid diagnosis and prompt treatment to prevent vision loss, particularly in infants. Our case confirms that oral propranolol may be regarded as a safe drug for periorbital IH with an excellent outcome.

Project description:OBJECTIVE:Infantile hemangiomas (IHs) are the most common benign vascular neoplasms of infancy, characterized by a rapid growth phase followed by a spontaneous involution, or triggered by propranolol treatment by poorly understood mechanisms. LIN28/let-7 axis plays a central role in the regulation of stem cell self-renewal and tumorigenesis. However, the role of LIN28B/let-7 signaling in IH pathogenesis has not yet been elucidated. APPROACH AND RESULTS:LIN28B is highly expressed in proliferative IH and is less expressed in involuted and in propranolol-treated IH samples as measured by immunofluorescence staining and quantitative RT-PCR. Small RNA sequencing analysis of IH samples revealed a decrease in microRNAs that target LIN28B, including let-7, and an increase in microRNAs in the mir-498(46) cistron. Overexpression of LIN28B in HEK293 cells induced the expression of miR-516b in the mir-498(46) cistron. Propranolol treatment of induced pluripotent stem cells, which express mir-498(46) endogenously, reduced the expression of both LIN28B and mir-498(46) and increased the expression of let-7. Furthermore, propranolol treatment reduced the proliferation of induced pluripotent stem cells and induced epithelial-mesenchymal transition. CONCLUSIONS:This work uncovers the role of the LIN28B/let-7 switch in IH pathogenesis and provides a novel mechanism by which propranolol induces IH involution. Furthermore, it provides therapeutic implications for cancers in which the LIN28/let-7 pathway is imbalanced.

Project description:This study aimed to characterize the population pharmacokinetics and exposure-response relationship of propranolol (Hemangiol® Syrup for Pediatric) in infants with infantile hemangioma. Using nonlinear mixed-effects modeling with 63 pooled sets of plasma concentration-time data from 32 Japanese patients aged 35-150 days, we described the disposition of propranolol adequately by a 1-compartment model with first-order absorption. The estimated population mean apparent clearance and apparent central volume of distribution were 9.34 L/h and 146 L, respectively. Body weight and postnatal age influenced the population pharmacokinetic model. The clinical end points-success (complete or nearly complete resolution of the target hemangioma) and failure-at weeks 12 and 24 were characterized by logistic regression using the area under the concentration-time curve (AUC), estimated from the final population pharmacokinetic model, as an exposure predictor. The logistic regression showed that a higher AUC was associated with a higher probability of successful treatment. At each exposure level, probability of successful treatment was correlated with gestational age and treatment duration. Model-predicted probabilities of successful treatment were consistent with actual results in the clinical trial. Simulations using several dosing regimens indicated that oral propranolol at 3 mg/kg per day was effective and would be appropriate for treating Japanese infants. These simulation results can support optimization of dosing regimens, such as selecting amounts, treatment durations, and dosing intervals, for clinical use.

Project description:Background Propranolol is a first-line clinical drug for infantile haemangiomas (IH) therapy. Nevertheless, resistance to propranolol is observed in some patients with IH. Circular RNAs (circRNAs) has been increasingly reported to act as a pivotal regulator in tumor progression. However, the underlying mechanism of circRNAs in IH remains unclear. Methods Quantitative real-time polymerase chain reaction was performed to detect Circ_0000915, miR-890 and RNF187 expression. Protein levels were determined using western blot. CCK-8 assay was used to measure cell proliferation. Caspase-3 activity assay and flow cytometry were conducted to determine cell apoptosis. Luciferase reporter assay was carried out to assess the interaction between miR-890 and Circ_0000915 or RNF187. Chromatin immunoprecipitation assay was performed to detect the interaction between STAT3 and Circ_0000915 promoter. Biotin pull-down assay was used to detect the direct interaction between miR-890 and Circ_0000915. In vivo experiments were performed to measure tumor formation. Results Here, we discovered depletion of Circ_0000915 increased propranolol sensitivity of haemangioma derived stem cells (HemSCs) both in vitro and in vivo, whereas forced expression of Circ_0000915 exhibited opposite effects. Mechanistically, Circ_0000915, transcriptionally induced by IL-6/STAT3 pathway, competed with RNF187 for the biding site in miR-890, led to upregulation of RNF187 by acting as a miR-890 “sponge”. Furthermore, silence of miR-890 reversed increased propranolol sensitivity of HemSCs due to Circ_0000915 ablation. Moreover, increased Circ_0000915 and RNF187 levels were observed in IH tissues and positively associated with propranolol resistance, miR-890 exhibited an inverse expression pattern. Conclusion We thereby uncover the activation of IL-6/STAT3/Circ_0000915/miR-890/RNF187 axis in propranolol resistance of IH, and provide therapeutic implications for patients of IH with propranolol resistance.

Project description:Infantile hemangioma (IH) with concurrent cleft lip and palate is a rare case. Surgical management is often considered as the best management for infantile hemangioma with concurrent cleft lip and palate. However, considering the functionality aspect and aesthetic appearance, a plastic surgeon can also consider non-surgical management without interrupting the surgical timeline for the cleft lip and palate. This case report aimed to describe the role of oral propranolol and oral methylprednisolone for infantile hemangioma with concurrent cleft lip and palate alongside the surgical management for cleft lip and palate. A 2-month-old presented with complaints of swelling in her right upper nose and cheek along with cleft lip and palate. She was treated with oral propranolol and oral methylprednisolone. Labioplasty was performed when she was three months old. Palatoplasty and nasorraphy were done when she was one year old. A significant reduction of the hemangioma was seen and the corrective procedures showed a good result. The use of propranolol and methylprednisolone for infantile hemangioma in our patient shows a good result even when combined with labioplasty, palatoplasty, and nasorraphy for cleft lip and palate. The management of infantile hemangioma with concurrent cleft lip and palate using oral propranolol and oral methylprednisolone shows a good result with no side effects and can be elaborated with labioplasty, palatoplasty, and nasorraphy, and will not interrupt the cleft lip and palate surgical timeline.
